D.   Risk Factors.

Risks Relating to Our Financial Position and Need for Capital

We may need substantial additional funding for our product development programs and commercialization efforts. If we are unable to raise capital on acceptable terms when needed, we could incur losses and be forced to delay, reduce or eliminate such efforts.

We expect our expenses to increase significantly in connection with our ongoing activities, particularly as we or our collaboration partners advance the clinical development of our eight clinical drug candidates which are currently in active or completed clinical studies in various countries. We will incur significant expenses as we continue research and development and initiate additional clinical trials of, and seek regulatory approval for, these and other future drug candidates. In addition, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution in China for any of our unpartnered drug candidates that may be approved in the future. In particular, the costs that may be required for the manufacture of any drug candidate that receives regulatory approval may be substantial as we may have to modify or increase the production capacity at our current manufacturing facilities or contract with third-party manufacturers. We may also incur expenses as we create additional infrastructure and expand our U.S.-based clinical team to support our operations at our U.S. subsidiary, Hutchison MediPharma International Inc. Accordingly, we may need to obtain substantial funding in connection with our continuing operations through public or private equity offerings, debt financings, collaborations or licensing arrangements or other sources. If we are unable to raise capital when needed or on attractive terms, we could incur losses and be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

Our net cash used in operating activities was $8.9 million, $32.8 million and $80.9 million for the years ended December 31, 2017, 2018 and 2019, respectively. We believe, however, that our expected cash flow from operations, including dividends from our Commercial Platform and milestone and other payments from our collaboration partners, our cash and cash equivalents and short-term investments as well as our unutilized bank facilities as of December 31, 2019, including: (i) the aggregate HK$424.0 million ($54.4 million) revolving credit facilities with The HongKong Shanghai Banking Corporation Limited, or HSBC, (ii) the HK$351.0 million ($45.0 million) revolving credit facility with Bank of America N.A., and (iii) the HK$156.0 million ($20.0 million) revolving credit facility with Deutsche Bank AG, Hong Kong Branch, or Deutsche Bank AG, will enable us to fund our operating expenses, debt service and capital expenditure requirements for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including:

● the number and development requirements of the drug candidates we pursue;

● the scope, progress, timing, results and costs of researching and developing our drug candidates, and conducting pre-clinical and clinical trials;

● the cost, timing and outcome of regulatory review of our drug candidates;

● the cost and timing of commercialization activities, including product manufacturing, marketing, sales and distribution, for our drug candidates for which we receive regulatory approval;

● the amount and timing of any milestone payments from our collaboration partners, with whom we cooperate with respect to the development and potential commercialization of certain of our drug candidates;

● the cash received from commercial sales of drug candidates for which we receive regulatory approval;

● our ability to establish and maintain strategic partnerships, collaboration, licensing or other arrangements and the financial terms of such agreements;

● the cost, timing and outcome of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims;

11

● our headcount growth and associated costs, particularly as we expand our clinical activities in the United States and Europe; and

● the costs of operating as a public company listed in the United States and United Kingdom.

Identifying potential drug candidates and conducting pre-clinical testing and clinical trials is a time-consuming, expensive and uncertain process that may take years to complete, and our commercial revenue, if any, will be derived from sales of products that we do not expect to be commercially available until we receive regulatory approval, if at all. We may never generate the necessary data or results required for certain drug candidates to obtain regulatory approval, and even if approved, they may not achieve commercial success. Accordingly, we will need to continue to rely on financing to achieve our business objectives. Adequate financing may not be available to us on acceptable terms, or at all.

Raising capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to technologies or drug candidates.

We expect to finance our cash needs in part through cash flow from our operations, including dividends from our Commercial Platform, and we may also rely on raising capital through a combination of public or private equity offerings, debt financings and/or license and development agreements with collaboration partners. In addition, we may seek capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that we raise capital through the sale of equity or convertible debt securities, the ownership interest of our shareholders may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect the rights of our existing shareholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions, such as incurring additional debt, making capital expenditures or declaring dividends. Additional debt financing would also result in increased fixed payment obligations.

In addition, if we raise funds through collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or drug candidates or grant licenses on terms that may not be favorable to us. We may also lose control of the development of drug candidates, such as the pace and scope of clinical trials, as a result of such third-party arrangements. If we are unable to raise funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market drug candidates that we would otherwise prefer to develop and market ourselves.

Our existing and any future indebtedness could adversely affect our ability to operate our business.

Our outstanding indebtedness combined with current and future financial obligations and contractual commitments, including any additional indebtedness beyond our current facilities with HSBC, Bank of America N.A. and Deutsche Bank AG could have significant adverse consequences, including:

● requiring us to dedicate a portion of our cash resources to the payment of interest and principal, and prepayment and repayment fees and penalties, thereby reducing money available to fund working capital, capital expenditures, product development and other general corporate purposes;

● increasing our vulnerability to adverse changes in general economic, industry and market conditions;

● subjecting us to restrictive covenants that may reduce our ability to take certain corporate actions or obtain further debt or equity financing;

● limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and

● placing us at a competitive disadvantage compared to our competitors that have less debt or better debt servicing options.

12

We intend to satisfy our current and future debt service obligations with our existing cash and cash equivalents and short-term investments. Nevertheless, we may not have sufficient funds, and may be unable to arrange for financing, to pay the amounts due under our existing debt. Failure to make payments or comply with other covenants under our existing debt instruments could result in an event of default and acceleration of amounts due.

We are subject to liquidity risk with respect to our investments in our joint ventures.

Our interests in our joint ventures are subject to liquidity risk. Such investments are not as liquid as other investment products as there is no cash flow until dividends are declared and received by us even if such joint ventures are profitable. Furthermore, our ability to promptly sell one or more of our interests in our joint ventures in response to changing corporate strategy or economic, financial and investment conditions is limited. The market for such investments can be affected by various factors, such as general economic and market conditions, availability of financing, interest rates and investor demand, many of which are beyond our control. If we determine to sell any of our joint venture investments, we cannot predict if we will be successful or whether any price or other terms offered by a prospective purchaser would be acceptable to us.

Risks Relating to Our Innovation Platform and Development of Our Drug Candidates

Historically, our in-house research and development division, known as our Innovation Platform, has not generated significant profits or has operated at a net loss. Our future profitability is dependent on the successful commercialization of our drug candidates.

To date, fruquintinib is our only drug candidate that has been approval for sale, and it has only been approved for sale for the treatment of third-line metastatic colorectal cancer patients in China. We do not expect to be significantly profitable unless and until we generate substantial royalties from fruquintinib and/or successfully commercialize our other drug candidates. We expect to incur significant sales and marketing costs as we prepare to commercialize our drug candidates.

Successful commercialization of our drug candidates is subject to many risks. Fruquintinib is currently marketed by our partner, Eli Lilly. Under our amended license and collaboration agreement with Eli Lilly, we may be granted promotion and distribution rights to fruquintinib for certain provinces in China in the future. We have never, as an organization, launched or commercialized any of our drug candidates, and there is no guarantee that we will be able to successfully commercialize any of our drug candidates for their approved indications. There are numerous examples of failures to meet expectations of market potential, including by pharmaceutical companies with more experience and resources than us. While we have an established network of medical sales representatives in China operated by our Commercial Platform, we will need to refine and further develop an oncology and immunology-focused sales team in order to successfully commercialize our drug candidates. Even if we are successful in developing our commercial team, there are many factors that could cause the commercialization of fruquintinib or our other drug candidates to be unsuccessful, including a number of factors that are outside our control. In the case of fruquintinib, for example, the third-line metastatic colorectal cancer patient population in China may be smaller than we estimate or physicians may be unwilling to prescribe, or patients are unwilling to take, fruquintinib due to, among other reasons, its pricing. Additionally, any negative development for fruquintinib in clinical development in additional indications, or in regulatory processes in other jurisdictions, may adversely impact the commercial results and potential of fruquintinib in China and globally. Thus, significant uncertainty remains regarding the commercial potential of fruquintinib.

We may not achieve profitability after generating royalties from fruquintinib and/or sales from our other drug candidates, if ever. If the commercialization of fruquintinib and/or our other drug candidates is unsuccessful or perceived as disappointing, our stock price could decline significantly and the long-term success of the product and our company could be harmed.

All of our drug candidates, other than fruquintinib for one indication in China, are still in development. If we are unable to obtain regulatory approval and ultimately commercialize our drug candidates, or if we experience significant delays in doing so, our business will be materially harmed.

All of our drug candidates are still in development, including fruquintinib which has been approved for the treatment of third-line metastatic colorectal cancer patients in China but is still in development in the United States for this indication and in China and the United States for other cancer indications.

13

Although we receive certain payments from our collaboration partners, including upfront payments and payments for achieving certain development, regulatory or commercial milestones, for certain of our drug candidates, our ability to generate revenue from our drug candidates is dependent on their receipt of regulatory approval for and successful commercialization of such products, which may never occur. Each of our drug candidates in development will require additional pre-clinical and/or clinical trials, regulatory approval in multiple jurisdictions, manufacturing supply, substantial investment and significant marketing efforts before we generate any revenue from product sales. The success of our drug candidates will depend on several factors, including the following:

● successful completion of pre-clinical and/or clinical trials;

● successful enrollment in, and completion of, clinical trials;

● receipt of regulatory approvals from applicable regulatory authorities for planned clinical trials, future clinical trials, drug registrations or post-approval trials;

● successful completion of all safety studies required to obtain regulatory approval and/or fulfillment of post-approval requirements in the United States, China and other jurisdictions for our drug candidates;

● adapting our commercial manufacturing capabilities to the specifications for our drug candidates for clinical supply and commercial manufacturing;

● obtaining and maintaining patent and trade secret protection or regulatory exclusivity for our drug candidates;

● launching commercial sales of our drug candidates, if and when approved, whether alone or in collaboration with others;

● acceptance of the drug candidates, if and when approved, by patients, the medical community and third-party payors;

● effectively competing with other therapies;

● obtaining and maintaining healthcare coverage and adequate reimbursement;

● enforcing and defending intellectual property rights and claims; and

● maintaining a continued acceptable safety profile of the drug candidates following approval.

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our drug candidates, which would materially harm our business.

Our primary approach to the discovery and development of drug candidates focuses on the inhibition of kinases, some of which are unproven.

A primary focus of our research and development efforts is on identifying kinase targets for which drug compounds previously developed by others affecting those targets have been unsuccessful due to limited selectivity, off-target toxicity and other problems. We then work to engineer drug candidates which have the potential to have superior efficacy, safety and other features as compared to such prior drug compounds. We also focus on developing drug compounds with the potential to be global best-in-class/next-generation therapies for validated kinase targets.

Even if we are able to develop compounds that successfully target the relevant kinases in pre-clinical studies, we may not succeed in demonstrating safety and efficacy of the drug candidates in clinical trials. Even if we are able to demonstrate safety and efficacy of compounds in certain indications in certain jurisdictions, we may not succeed in demonstrating the same in other indications or same indications in other jurisdictions. As a result, our efforts may not result in the discovery or development of drugs that are commercially viable or are superior to existing drugs or other therapies on the market. While the results of pre-clinical studies, early-stage clinical trials as well as clinical trials in certain indications have suggested that certain of our drug candidates may successfully inhibit kinases and may have significant utility in several cancer indications, potentially in combination with other cancer drugs, chemotherapy and immunotherapies, we have not yet demonstrated efficacy and safety for many of our drug candidates in later stage clinical trials.

14

We may expend our limited resources to pursue a particular drug candidate or indication and fail to capitalize on drug candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we must limit our research programs to specific drug candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other drug candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial drugs or profitable market opportunities. In addition, if we do not accurately evaluate the commercial potential or target market for a particular drug candidate, we may relinquish valuable rights to that drug candidate through collaboration, licensing or other royalty arrangements when it would have been more advantageous for us to retain sole development and commercialization rights to such drug candidate.

We have no history of commercializing our internally developed drugs, which may make it difficult to evaluate our future prospects.

The operations of our Innovation Platform have been limited to developing and securing our technology and undertaking pre-clinical studies and clinical trials of our drug candidates, either independently or with our collaboration partners. We have a limited history of successfully completing development of our drug candidates, obtaining marketing approvals, manufacturing our internally developed drugs at a commercial scale. In addition, we have not yet demonstrated the ability to successfully conduct sales and regulatory activities necessary for successful product commercialization of our drug candidates. While we believe we will be able to successfully leverage our existing Commercial Platform and have begun to build an oncology-focused sales force to launch our drug candidates in China once approved, any predictions about our future success or viability may not be as accurate as they could be if we had an extensive history of successfully developing and commercializing our internally developed drug candidates.

The regulatory approval processes of the U.S. Food and Drug Administration, or FDA, National Medical Products Administration of China, or NMPA, and comparable authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our drug candidates, our ability to generate revenue will be materially impaired.

Our drug candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale, distribution, import and export, are subject to comprehensive regulation by the FDA, NMPA and other regulatory agencies in the United States and China and by comparable authorities in other countries. Securing regulatory approval requires the submission of extensive pre-clinical and clinical data and supporting information to the various regulatory authorities for each therapeutic indication to establish the drug candidate’s safety and efficacy. Securing regulatory approval also requires the submission of information about the drug manufacturing process to, and inspection of manufacturing facilities by, the relevant regulatory authority. Our drug candidates may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude our obtaining regulatory approval or prevent or limit commercial use.

The process of obtaining regulatory approvals in the United States, China and other countries is expensive, may take many years if additional clinical trials are required, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the drug candidates involved. Changes in regulatory approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted New Drug Application, or NDA, pre-market approval or equivalent application types, may cause delays in the approval or rejection of an application. The FDA, NMPA and comparable authorities in other countries have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional pre-clinical, clinical or other studies. Our drug candidates could be delayed in receiving, or fail to receive, regulatory approval for many reasons, including the following:

● the FDA, NMPA or comparable regulatory authorities may disagree with the number, design, size, conduct or implementation of our clinical trials;

● we may be unable to demonstrate to the satisfaction of the FDA, NMPA or comparable regulatory authorities that a drug candidate is safe and effective for its proposed indication;

● the results of clinical trials may not meet the level of statistical significance required by the FDA, NMPA or comparable regulatory authorities for approval;

15

● we may be unable to demonstrate that a drug candidate’s clinical and other benefits outweigh its safety risks;

● the FDA, NMPA or comparable regulatory authorities may disagree with our interpretation of data from pre-clinical studies or clinical trials;

● the data collected from clinical trials of our drug candidates may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory approval in the United States or elsewhere;

● the FDA, NMPA or comparable regulatory authorities may fail to approve the manufacturing processes for our clinical and commercial supplies;

● the approval policies or regulations of the FDA, NMPA or comparable regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval;

● the FDA, NMPA or comparable regulatory authority may prioritize treatments for emerging health crises, such as Covid-19, resulting in delays for our drug candidates;

● the FDA, NMPA or comparable regulatory authorities may restrict the use of our products to a narrow population; and

● our collaboration partners or CROs that are retained to conduct the clinical trials of our drug candidates may take actions that materially and adversely impact the clinical trials.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our drug candidates for fewer or more limited indications than we request, may not approve the price we intend to charge for our drugs, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a drug candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that drug candidate. Any of the foregoing scenarios could materially harm the commercial prospects for our drug candidates.

Furthermore, even though the NMPA has granted approval for fruquintinib for use in third-line metastatic colorectal cancer patients, we are still subject to substantial, ongoing regulatory requirements. See “—Even if we receive regulatory approval for our drug candidates, we are subject to ongoing obligations and continued regulatory review, which may result in significant additional expense.”

If the FDA, NMPA or another regulatory agency revokes its approval of, or if safety, efficacy, manufacturing or supply issues arise with, any therapeutic that we use in combination with our drug candidates, we may be unable to market such drug candidate or may experience significant regulatory delays or supply shortages, and our business could be materially harmed.

We are currently focusing on the clinical development of savolitinib as both a monotherapy and in combination with immunotherapy (Imfinzi), targeted therapies (Tagrisso and Iressa) and chemotherapy (Taxotere). We are also focusing on the clinical development of our drug candidate fruquintinib as both a monotherapy and in combination with immunotherapies (Tyvyt and genolimzumab), chemotherapy (Taxol) and targeted therapies (Iressa). In addition, we are currently focusing on the clinical development of surufatinib (previously named sulfatinib) as a monotherapy and in combination with immunotherapies (Tuoyi and Tyvyt). However, we did not develop and we do not manufacture or sell, Tagrisso, Iressa, Taxotere, Taxol, Imfinzi, Tyvyt, genolimzumab, Tuoyi or any other therapeutic we use in combination with our drug candidates. We may also seek to develop our drug candidates in combination with other therapeutics in the future.

If the FDA, NMPA or another regulatory agency revokes its approval, or does not grant approval, of any of these and other therapeutics we use in combination with our drug candidates, we will not be able to market our drug candidates in combination with such therapeutics. If safety or efficacy issues arise with these or other therapeutics that we seek to combine with our drug candidates in the future, we may experience significant regulatory delays, and we may be required to redesign or terminate the applicable clinical trials. In addition, if manufacturing or other issues result in a supply shortage of these or any other combination therapeutics, we may not be able to complete clinical development of savolitinib, fruquintinib, surufatinib, HMPL-523 and/or another of our drug candidates on our current timeline or at all.

16

Even if one or more of our drug candidates were to receive regulatory approval for use in combination with a therapeutic, we would continue to be subject to the risk that the FDA, NMPA or another regulatory agency could revoke its approval of the combination therapeutic, or that safety, efficacy, manufacturing or supply issues could arise with one of these combination therapeutics. This could result in savolitinib, fruquintinib, surufatinib, HMPL-523 or one of our other products being removed from the market or being less successful commercially.

We face substantial competition, which may result in others discovering, developing or commercializing drugs before or more successfully than we do.

The development and commercialization of new drugs is highly competitive. We face competition with respect to our current drug candidates, and will face competition with respect to any drug candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market drugs or are pursuing the development of therapies in the field of kinase inhibition for cancer and other diseases. Some of these competitive drugs and therapies are based on scientific approaches that are the same as or similar to our approach, and others are based on entirely different approaches. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization. Specifically, there are a large number of companies developing or marketing treatments for cancer and immunological diseases, including many major pharmaceutical and biotechnology companies.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, pre-clinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. Mergers and acquisitions in the pharmaceutical, biotechnology and diagnostic industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any drugs that we or our collaborators may develop. Our competitors also may obtain FDA, NMPA or other regulatory approval for their drugs more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we or our collaborators are able to enter the market. The key competitive factors affecting the success of all of our drug candidates, if approved, are likely to be their efficacy, safety, convenience, price, the level of generic competition and the availability of reimbursement from government and other third-party payors.

Clinical development involves a lengthy and expensive process with an uncertain outcome.

There is a risk of failure for each of our drug candidates. It is difficult to predict when or if any of our drug candidates will prove effective and safe in humans or will receive regulatory approval. Before obtaining regulatory approval from regulatory authorities for the sale of any drug candidate, we or our collaboration partners must complete pre-clinical studies and then conduct extensive clinical trials to demonstrate the safety and efficacy of our drug candidates in humans. Clinical testing is expensive, difficult to design and implement and can take many years to complete. The outcomes of pre-clinical development testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, pre-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their drug candidates performed satisfactorily in pre-clinical studies and clinical trials have nonetheless failed to obtain regulatory approval of their drug candidates. Our current or future clinical trials may not be successful.

Commencing each of our clinical trials is subject to finalizing the trial design based on ongoing discussions with the FDA, NMPA or other regulatory authorities. The FDA, NMPA and other regulatory authorities could change their position on the acceptability of our trial designs or clinical endpoints, which could require us to complete additional clinical trials or impose approval conditions that we do not currently expect. Successful completion of our clinical trials is a prerequisite to submitting an NDA or analogous filing to the FDA, NMPA or other regulatory authorities for each drug candidate and, consequently, the ultimate approval and commercial marketing of our drug candidates. We do not know whether any of our clinical trials will begin or be completed on schedule, if at all.

17

We and our collaboration partners may incur additional costs or experience delays in completing our pre-clinical or clinical trials, or ultimately be unable to complete the development and commercialization of our drug candidates.

We and our collaboration partners, including AstraZeneca and Eli Lilly, may experience delays in completing our pre-clinical or clinical trials, and numerous unforeseen events could arise during, or as a result of, future clinical trials, which could delay or prevent us from receiving regulatory approval, including:

● regulators or institutional review boards, or IRBs, or ethics committees or the China Human Genetic Resources Administration Office may not authorize us or our investigators to commence or conduct a clinical trial at a prospective trial site;

● we may experience delays in reaching, or we may fail to reach, agreement on acceptable terms with prospective trial sites and prospective CROs, who conduct clinical trials on behalf of us and our collaboration partners, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

● clinical trials may produce negative or inconclusive results, and we or our collaboration partners may decide, or regulators may require us or them, to conduct additional clinical trials or we may decide to abandon drug development programs;

● the number of patients required for clinical trials of our drug candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate or participants may drop out of these clinical trials or fail to return for post-treatment follow-up at a higher rate than we anticipate;

● third-party contractors used in our clinical trials may fail to comply with regulatory requirements or meet their contractual obligations in a timely manner, or at all, or may deviate from the clinical trial protocol or drop out of the trial, which may require that we or our collaboration partners add new clinical trial sites or investigators;

● we or our collaboration partners may elect to, or regulators, IRBs or ethics committees may require that we or our investigators, suspend or terminate clinical research for various reasons, including non-compliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks;

● the cost of clinical trials of our drug candidates may be greater than we anticipate;

● the supply or quality of our drug candidates, companion diagnostics, if any, or other materials necessary to conduct clinical trials of our drug candidates may be insufficient or inadequate; and

● our drug candidates may have undesirable side effects or unexpected characteristics, causing us or our investigators, regulators, IRBs or ethics committees to suspend or terminate the trials, or reports may arise from pre-clinical or clinical testing of other cancer therapies that raise safety or efficacy concerns about our drug candidates.

We could encounter regulatory delays if a clinical trial is suspended or terminated by us or our collaboration partners, by, as applicable, the IRBs of the institutions in which such trials are being conducted, by the Data Safety Monitoring Board, which is an independent group of experts that is formed to monitor clinical trials while ongoing, or by the FDA, NMPA or other regulatory authorities. Such authorities may impose a suspension or termination due to a number of factors, including: a failure to conduct the clinical trial in accordance with regulatory requirements or the applicable clinical protocols, inspection of the clinical trial operations or trial site by the FDA, NMPA or other regulatory authorities that results in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Many of the factors that cause a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our drug candidates. Further, the FDA, NMPA or other regulatory authorities may disagree with our clinical trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after it has reviewed and commented on the design for our clinical trials.

18

If we or our collaboration partners are required to conduct additional clinical trials or other testing of our drug candidates beyond those that are currently contemplated, if we or our collaboration partners are unable to successfully complete clinical trials of our drug candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

● be delayed in obtaining regulatory approval for our drug candidates;

● not obtain regulatory approval at all;

● obtain approval for indications or patient populations that are not as broad as intended or desired;

● be subject to post-marketing testing requirements; or

● have the drug removed from the market after obtaining regulatory approval.

Our drug development costs will also increase if we experience delays in testing or regulatory approvals. We do not know whether any of our clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant pre-clinical study or clinical trial delays also could allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our drug candidates and may harm our business and results of operations. Any delays in our clinical development programs may harm our business, financial condition and prospects significantly.

If we or our collaboration partners experience delays or difficulties in the enrollment of patients in clinical trials, the progress of such clinical trials and our receipt of necessary regulatory approvals could be delayed or prevented.

We or our collaboration partners may not be able to initiate or continue clinical trials for our drug candidates if we or our collaboration partners are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA, NMPA or similar regulatory authorities. In particular, we and our collaboration partners have designed many of our clinical trials, and expect to design future trials, to include some patients with the applicable genomic alteration that causes the disease with a view to assessing possible early evidence of potential therapeutic effect. Genomically defined diseases, however, may have relatively low prevalence, and it may be difficult to identify patients with the applicable genomic alteration. In addition, for many of our trials, we focus on enrolling patients who have failed their first or second-line treatments, which limits the total size of the patient population available for such trials. The inability to enroll a sufficient number of patients with the applicable genomic alteration or that meet other applicable criteria for our clinical trials would result in significant delays and could require us or our collaboration partners to abandon one or more clinical trials altogether.

In addition, some of our competitors have ongoing clinical trials for drug candidates that treat the same indications as our drug candidates, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ drug candidates.

Patient enrollment may be affected by other factors including:

● the severity of the disease under investigation;

● the total size and nature of the relevant patient population;

● the design and eligibility criteria for the clinical trial in question;

● the availability of an appropriate genomic screening test/companion diagnostic;

● the perceived risks and benefits of the drug candidate under study;

● the efforts to facilitate timely enrollment in clinical trials;

19

● the patient referral practices of physicians;

● the availability of competing therapies which are undergoing clinical trials;

● the ability to monitor patients adequately during and after treatment; and

● the proximity and availability of clinical trial sites for prospective patients.

Enrollment delays in our clinical trials may result in increased development costs for our drug candidates, which could cause the value of our company to decline and limit our ability to obtain financing.

Our drug candidates may cause undesirable side effects that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following regulatory approval, if any.

Undesirable side effects caused by our drug candidates could cause us or our collaboration partners to interrupt, delay or halt clinical trials or could cause regulatory authorities to interrupt, delay or halt our clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, NMPA or other regulatory authorities. In particular, as is the case with all oncology drugs, it is likely that there may be side effects, for example, hand-foot syndrome, associated with the use of certain of our drug candidates. Results of our trials could reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event, our trials could be suspended or terminated and the FDA, NMPA or comparable regulatory authorities could order us to cease further development of or deny approval of our drug candidates for some or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

Further, our drug candidates could cause undesirable side effects related to off-target toxicity. Many of the currently approved tyrosine kinase inhibitors have been associated with off-target toxicities because they affect multiple kinases. While we believe that the kinase selectivity of our drug candidates has the potential to significantly improve the unfavorable adverse off-target toxicity issues, if patients were to experience off-target toxicity, we may not be able to achieve an effective dosage level, receive approval to market, or achieve the commercial success we anticipate with respect to any of our drug candidates, which could prevent us from ever generating revenue or achieving profitability. Many compounds that initially showed promise in early-stage testing for treating cancer have later been found to cause side effects that prevented further development of the compound.

Clinical trials assess a sample of the potential patient population. With a limited number of patients and duration of exposure, rare and severe side effects of our drug candidates may only be uncovered with a significantly larger number of patients exposed to the drug candidate. If our drug candidates receive regulatory approval and we or others identify undesirable side effects caused by such drug candidates (or any other similar drugs) after such approval, a number of potentially significant negative consequences could result, including:

● regulatory authorities may withdraw or limit their approval of such drug candidates;

● regulatory authorities may require the addition of labeling statements, such as a “boxed” warning or a contra-indication;

● we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

● we may be required to change the way such drug candidates are distributed or administered, conduct additional clinical trials or change the labeling of the drug candidates;

● regulatory authorities may require a Risk Evaluation and Mitigation Strategy, or REMS, plan to mitigate risks, which could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools;

● we may be subject to regulatory investigations and government enforcement actions;

● we may decide to remove such drug candidates from the marketplace;

20

● we could be sued and held liable for injury caused to individuals exposed to or taking our drug candidates; and

● our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the affected drug candidates and could substantially increase the costs of commercializing our drug candidates, if approved, and significantly impact our ability to successfully commercialize our drug candidates and generate revenue.

We and our collaboration partners have conducted and intend to conduct additional clinical trials for certain of our drug candidates at sites outside the United States, and the FDA may not accept data from trials conducted in such locations or may require additional U.S.-based trials.

We and our collaboration partners have conducted, currently are conducting and intend in the future to conduct, clinical trials outside the United States, particularly in China where our Innovation Platform is headquartered as well as in other jurisdictions such as Australia, Canada, South Korea, U.K. and Spain.

Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of these data is subject to certain conditions imposed by the FDA. For example, the clinical trial must be well designed and conducted by qualified investigators in accordance with current good clinical practices, or GCPs, including review and approval by an independent ethics committee and receipt of informed consent from trial patients. The trial population must also adequately represent the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. Generally, the patient population for any clinical trial conducted outside of the United States must be representative of the population for which we intend to seek approval in the United States. In addition, while these clinical trials are subject to applicable local laws, FDA acceptance of the data will be dependent upon its determination that the trials also comply with all applicable U.S. laws and regulations. There can be no assurance that the FDA will accept data from trials conducted outside of the United States. If the FDA does not accept the data from our clinical trials conducted outside the United States, it would likely result in the need for additional clinical trials, which would be costly and time-consuming and delay or permanently halt our ability to develop and market these or other drug candidates in the United States.

In addition, there are risks inherent in conducting clinical trials in jurisdictions outside the United States including:

● regulatory and administrative requirements of the jurisdiction where the trial is conducted that could burden or limit our ability to conduct our clinical trials;

● foreign exchange fluctuations;

● manufacturing, customs, shipment and storage requirements;

● cultural differences in medical practice and clinical research; and

● the risk that patient populations in such trials are not considered representative as compared to patient populations in the United States and other markets.

21

If we are unable to obtain and/or maintain priority review or another expedited registration pathway for our drug candidates, the time and cost we incur to obtain regulatory approvals may increase. Even if we receive such approvals, they may not lead to a faster development, review or approval process.

Under the Opinions on Priority Review and Approval for Encouraging Drug Innovation, the NMPA may grant priority review approval to (i) certain drugs with distinctive clinical value, including innovative drugs not sold within or outside China, (ii) new drugs with clinical treatment advantages for AIDS and other rare diseases, and (iii) drugs which have been concurrently filed with the competent drug approval authorities in the United States or European Union for marketing authorization and passed such authorities’ onsite inspections and are manufactured using the same production line in China. Priority review provides a fast track process for drug registration, and we anticipate that we may seek priority review for certain of our drug candidates.

A failure to obtain and/or maintain priority review or any other form of expedited development, review or approval for our drug candidates would result in a longer time period to commercialization of such drug candidate, could increase the cost of development of such drug candidate and could harm our competitive position in the marketplace. In addition, even if we obtain priority review, there is no guarantee that we will experience a faster review or approval compared to non-accelerated registration pathways or that a drug candidate will ultimately be approved for sale.

Although we have obtained orphan drug designation for surufatinib for the treatment of pancreatic neuroendocrine tumors in the United States, we may not be able to obtain or maintain the benefits associated with orphan drug status, including market exclusivity.

Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is intended to treat a rare disease or condition, which is generally defined as affecting fewer than 200,000 individuals in the United States. We have obtained orphan drug designation from the FDA for surufatinib for the treatment of pancreatic neuroendocrine tumors. Generally, if a drug with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug may be entitled to a seven-year period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same molecule for the same indication for that time period. We can provide no assurance that another drug will not receive marketing approval prior to our product candidates. Orphan drug exclusivity may be lost if the FDA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. In addition, even after a drug is granted orphan exclusivity and approved, the FDA can subsequently approve another drug for the same condition before the expiration of the seven-year exclusivity period if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.

Even if we receive regulatory approval for our drug candidates, we are subject to ongoing obligations and continued regulatory review, which may result in significant additional expense.

If the FDA, NMPA or a comparable regulatory authority approves any of our drug candidates, we will continue to be subject to extensive and ongoing regulatory requirements. For example, even though the NMPA has granted approval of fruquintinib, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for fruquintinib continue to be subject to the NMPA’s oversight. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with current good manufacturing processes.

Any regulatory approvals that we receive for our drug candidates may also be subject to limitations on the approved indicated uses for which the drug may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase IV clinical trials, and surveillance to monitor the safety and efficacy of the drug. In addition, regulatory policies may change or additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our drug candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any regulatory approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.

22

We may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with any of our drugs that receive regulatory approval.

Once a drug is approved by the FDA, NMPA or a comparable regulatory authority for marketing, it is possible that there could be a subsequent discovery of previously unknown problems with the drug, including problems with third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements. If any of the foregoing occurs with respect to our drug products, it may result in, among other things:

● restrictions on the marketing or manufacturing of the drug, withdrawal of the drug from the market, or drug recalls;

● fines, warning letters or holds on clinical trials;

● refusal by the FDA, NMPA or comparable regulatory authority to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of drug license approvals;

● drug seizure or detention, or refusal to permit the import or export of drugs; and

● injunctions or the imposition of civil or criminal penalties.

Any government investigation of alleged violations of law could require us to expend significant time and resources and could generate negative publicity. If we or our collaborators are not able to maintain regulatory compliance, regulatory approval that has been obtained may be lost and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations.

The incidence and prevalence for target patient populations of our drug candidates are based on estimates and third-party sources. If the market opportunities for our drug candidates are smaller than we estimate or if any approval that we obtain is based on a narrower definition of the patient population, our revenue and ability to achieve profitability will be adversely affected, possibly materially.

Periodically, we make estimates regarding the incidence and prevalence of target patient populations for particular diseases based on various third-party sources and internally generated analysis and use such estimates in making decisions regarding our drug development strategy, including determining indications on which to focus in pre-clinical or clinical trials.

These estimates may be inaccurate or based on imprecise data. For example, the total addressable market opportunity will depend on, among other things, their acceptance by the medical community and patient access, drug pricing and reimbursement. The number of patients in the addressable markets may turn out to be lower than expected, patients may not be otherwise amenable to treatment with our drugs, or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business.

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

We are highly dependent on the expertise of the members of our research and development team, as well as the other principal members of our management, including Christian Hogg, our Chief Executive Officer and director, and Weiguo Su, Ph.D., our Chief Scientific Officer and director. Although we have entered into employment agreements with our executive officers, each of them may terminate their employment with us at any time with three months’ prior written notice. We do not maintain “key person” insurance for any of our executives or other employees.

23

Recruiting and retaining qualified management, scientific, clinical, manufacturing and sales and marketing personnel will also be critical to our success. The loss of the services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize drugs. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. Failure to succeed in clinical trials may make it more challenging to recruit and retain qualified scientific personnel.

We have expanded our footprint and operations in the United States, and we intend to expand our international operations further in the future, but we may not achieve the results that we expect.

In early 2018, we opened our first office in the United States. While we have been involved in clinical and non-clinical development in North America and Europe for over a decade, the activities conducted by our new U.S. office will significantly broaden and scale our non-Asian clinical development and international operations. We intend to significantly expand our U.S. clinical team to support our increasing clinical activities in the United States and Europe. Conducting our business in multiple countries subjects us to a variety of risks and complexities that may materially and adversely affect our business, results of operations, financial condition and growth prospects, including, among other things:

● the increased complexity and costs inherent in managing international operations;

● diverse regulatory, financial and legal requirements, and any future changes to such requirements, in one or more countries where we are located or do business;

● country-specific tax, labor and employment laws and regulations;

● applicable trade laws, tariffs, export quotas, custom duties or other trade restrictions and any changes to them;

● challenges inherent in efficiently managing employees in diverse geographies, including the need to adapt systems, policies, benefits and compliance programs to differing labor and other regulations;

● changes in currency rates; and

● regulations relating to data security and the unauthorized use of, or access to, commercial and personal information.

As a result of our growth, our business and corporate structure has become more complex. There can be no assurance that we will effectively manage the increased complexity without experiencing operating inefficiencies or control deficiencies. Significant management time and effort is required to effectively manage the increased complexity of our company, and our failure to successfully do so could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

24

We may be restricted from transferring our scientific data abroad.

On March 17, 2018, the General Office of the State Council promulgated the Measures for the Management of Scientific Data (科學數據管理辦法), or the Scientific Data Measures, which provides a broad definition of scientific data and relevant rules for the management of scientific data. According to the Scientific Data Measures, enterprises in China must seek governmental approval before any scientific data involving a state secret may be transferred abroad or to foreign parties. Further, any researcher conducting research funded at least in part by the Chinese government is required to submit relevant scientific data for management by the entity to which such researcher is affiliated before such data may be published in any foreign academic journal. Given the term state secret is not clearly defined in the Scientific Data Measures, if and to the extent our research and development of drug candidates will be subject to the Scientific Data Measures and any subsequent laws as required by the relevant government authorities, we cannot assure you that we can always obtain relevant approvals for sending scientific data (such as the results of our pre-clinical studies or clinical trials conducted within China) abroad or to our foreign partners in China. If we are unable to obtain necessary approvals in a timely manner, or at all, our research and development of drug candidates may be hindered, which may materially and adversely affect our business, results of operations, financial conditions and prospects. If the relevant government authorities consider the transmission of our scientific data to be in violation of the requirements under the Scientific Data Measures, we may be subject to fines and other administrative penalties imposed by those government authorities.

Risks Relating to Our Commercial Platform and Sales of Our Commercial-stage Drug Candidates

Pharmaceutical companies in China are required to comply with extensive regulations and hold a number of permits and licenses to carry on their business. Our and our joint ventures’ ability to obtain and maintain these regulatory approvals is uncertain, and future government regulation may place additional burdens on the Commercial Platform business.

The pharmaceutical industry in China is subject to extensive government regulation and supervision. The regulatory framework addresses all aspects of operating in the pharmaceutical industry, including approval, production, distribution, advertising, licensing and certification requirements and procedures, periodic renewal and reassessment processes, registration of new drugs and environmental protection. Violation of applicable laws and regulations may materially and adversely affect our business. In order to manufacture and distribute pharmaceutical products in China, we and our joint ventures are required to:

● obtain a pharmaceutical manufacturing permit for each production facility from the relevant food and drug administrative authority;

● obtain a drug registration certificate, which includes a drug approval number, from the NMPA for each drug manufactured by us;

● obtain a pharmaceutical distribution permit from the NMPA; and

● renew the pharmaceutical manufacturing permits, the pharmaceutical distribution permits, drug registration certificates, among other requirements.

If we or our joint ventures are unable to obtain or renew such permits or any other permits or licenses required for our or their operations, we will not be able to engage in the manufacture and distribution of our products and our business may be adversely affected.

The regulatory framework regarding the pharmaceutical industry in China is subject to change and amendment from time to time. Any such change or amendment could materially and adversely impact our business, financial condition and results of operations. The PRC government has introduced various reforms to the Chinese healthcare system in recent years and may continue to do so, with an overall objective to expand basic medical insurance coverage and improve the quality and reliability of healthcare services. The specific regulatory changes under the reform still remain uncertain. The implementing measures to be issued may not be sufficiently effective to achieve the stated goals and, as a result, we may not be able to benefit from such reform to the level we expect, if at all. Moreover, the reform could give rise to regulatory developments, such as more burdensome administrative procedures, which may have an adverse effect on our business and prospects.

For further information regarding government regulation in China and other jurisdictions, see Item 4.B. “Business Overview—Regulation—Government Regulation of Pharmaceutical Product Development and Approval,” “Business Overview—Regulation—Coverage and Reimbursement” and “Business Overview—Regulation—Other Healthcare Laws.”

25

As a significant portion of our Commercial Platform business, which consists of our Prescription Drugs and Consumer Health divisions, is conducted through joint ventures, we are largely dependent on the success of our joint ventures and our receipt of dividends or other payments from our joint ventures for cash to fund our operations.

We are party to joint venture agreements with Shanghai Pharmaceuticals and Guangzhou Baiyunshan, relating to our non-consolidated joint ventures, which together form part of our Commercial Platform business. Our equity in the earnings of these non-consolidated joint ventures was $38.2 million, $38.3 million and $40.6 million for the years ended December 31, 2017, 2018 and 2019, respectively, as recorded in our consolidated financial statements. As such, our results of operations and financial performance have been, and will continue to be, affected by the financial performance of these joint ventures as well as any other equity investees we have or may have in the future. Furthermore, we have consolidated joint ventures with each of Sinopharm and Hain Celestial which accounted for substantially all of our Commercial Platform’s consolidated revenue for the years ended December 31, 2017, 2018 and 2019.

As a result, our ability to fund our operations and pay our expenses or to make future dividend payments, if any, is largely dependent on the earnings of our joint ventures and the payment of those earnings to us in the form of dividends. Payments to us by our joint ventures will be contingent upon our joint ventures’ earnings and other business considerations and may be subject to statutory or contractual restrictions. Each joint venture’s ability to distribute dividends to us is subject to approval by their respective boards of directors, which in the case of Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan are comprised of an equal number of representatives from each party.

Operationally, our joint venture partners have certain responsibilities and/or certain rights to exercise control or influence over operations and decision-making under the joint venture arrangements. Therefore, the success of our joint ventures depends on the efforts and abilities of our joint venture parties to varying degrees. For example, we share the ability to appoint the general manager of our joint venture with Guangzhou Baiyunshan, with each of us having a rotating four-year right, and therefore, our ability to manage the day-to-day operations of this joint venture is more limited. On the other hand, we appoint the general managers of Hutchison Sinopharm and Shanghai Hutchison Pharmaceuticals pursuant to the respective joint venture agreements governing these entities and therefore oversee the day-to-day management of these joint ventures. However, we still rely on our joint venture partners Sinopharm and Shanghai Pharmaceuticals to provide certain distribution and logistics services. See “—Risks Relating to Our Dependence on Third Parties—Joint ventures form an important part of our Commercial Platform business, and our ability to manage and develop the businesses conducted by these joint ventures depends in part on our relationship with our joint venture partners” for more information.

We intend to leverage the know-how and infrastructure of our Commercial Platform’s Prescription Drugs business to commercialize our internally developed drug candidates, but we may not be successful in adapting this business to successfully manufacture, sell and market our drug candidates if and when they are approved, and we may not be able to generate any revenue from such products.

Our Prescription Drugs business is primarily operated by our Shanghai Hutchison Pharmaceuticals and Hutchison Sinopharm joint ventures and currently has a manufacturing, sales and marketing infrastructure in China. We intend to leverage our experience operating our Prescription Drugs business to commercialize certain of our drug candidates in China, if approved. However, to do so, we must adapt our know-how and infrastructure to build a specific oncology and/or immunology focused sales and marketing team. There are risks involved with leveraging the experience from our current Prescription Drugs business. For example, recruiting and/or training a sales force in new oncology and immunology is time consuming and could delay any drug launch. Factors that may inhibit our efforts to commercialize our drug candidates include:

● our inability to recruit and retain adequate numbers of effective sales and marketing personnel;

● the inability of our sales personnel to obtain access to physicians or educate adequate numbers of physicians who then prescribe any future drugs; and

● the lack of complementary drugs to be offered by our sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines.

In such case, our business, results of operations, financial condition and prospects will be materially and adversely affected.

26

Our Commercial Platform faces substantial competition.

Our Commercial Platform’s Prescription Drugs business competes in the pharmaceutical industry in China, which is characterized by a number of established, large pharmaceutical companies, as well as some smaller emerging pharmaceutical companies. Our Prescription Drugs business competes with pharmaceutical companies engaged in the development, production, marketing or sales of prescription drugs, in particular cardiovascular drugs. The identities of the key competitors with respect to our Prescription Drugs business vary by product and, in certain cases, competitors have greater financial resources than us and may elect to focus these resources on developing, importing or in-licensing and marketing products in the PRC that are substitutes for our products and may have broader sales and marketing infrastructure with which to do so. Our Commercial Platform’s Consumer Health business also competes in a highly fragmented market in Asia.

The products sold through our Commercial Platform, which may include our drug candidates if they receive regulatory approval, may compete against products that have lower prices, superior performance, greater ease of administration or other advantages compared to our products. In some circumstances, price competition may drive our competitors to conduct illegal manufacturing processes to lower their manufacturing costs. Increased competition may result in price reductions, reduced margins and loss of market share, whether achieved by either legal or illegal means, any of which could materially and adversely affect our profit margins. We and our joint ventures may not be able to compete effectively against current and future competitors.

If we are not able to maintain and enhance brand recognition of the Commercial Platform’s products to maintain its competitive advantage, our reputation, business and operating results may be harmed.

We believe that market awareness of the products sold through our Commercial Platform, which include our joint ventures’ branded products, such as Baiyunshan and Shang Yao, and the brands of third-party products which are distributed through our joint ventures, has contributed significantly to the success of our Commercial Platform. We also believe that maintaining and enhancing such brands is critical to maintaining our competitive advantage. Although the sales and marketing staff of our Commercial Platform will continue to further promote such brands to remain competitive, they may not be successful. If our joint ventures are unable to further enhance brand recognition and increase awareness of their products, or if they are compelled to incur excessive marketing and promotion expenses in order to maintain brand awareness, our business and results of operations may be materially and adversely affected. Furthermore, our results of operations could be adversely affected if the Baiyunshan and Shang Yao brands, or the brands of any other products, or our reputation, are impaired by certain actions taken by our joint venture partners, distributors, competitors or relevant regulatory authorities.

Reimbursement may not be available for the products currently sold through our Commercial Platform or our drug candidates in China, the United States or other countries, which could diminish our sales or affect our profitability.

The regulations that govern pricing and reimbursement for pharmaceuticals vary widely from country to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after regulatory approval is granted. In some foreign markets, pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. Furthermore, once marketed and sold, government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. Adverse pricing reimbursement levels may hinder market acceptance of products sold by our Commercial Platform or drug candidates.

In China, for example, the Ministry of Human Resources and Social Security of the PRC or provincial or local human resources and social security authorities, together with other government authorities, review the inclusion or removal of drugs from the Medicines Catalogue for the National Basic Medical Insurance, Labor Injury Insurance and Childbirth System in China, or the National Reimbursement Drug List, or provincial or local medical insurance catalogues for the National Medical Insurance Program, and the category under which a drug will be classified, both of which affect the amounts reimbursable to program participants for their purchases of those medicines. These determinations are made based on a number of factors, including price and efficacy. Depending on the category under which a drug is classified in the provincial medicine catalogue, a National Medical Insurance Program participant residing in that province can be reimbursed for the full cost of Category A medicine and for the majority of the cost of a Category B medicine. In some instances, if the price range designated by the local or provincial government decreases, it may adversely affect our business and could reduce our total revenue, and if our revenue falls below production costs, we may stop manufacturing certain products. In November 2019, fruquintinib was added to China’s National Reimbursement Drug List as a Category B medicine.

27

In addition, in order to access certain local or provincial-level markets, our joint ventures are periodically required to enter into competitive bidding processes for She Xiang Bao Xin pills (the best-selling product of our Shanghai Hutchison Pharmaceuticals joint venture), Fu Fang Dan Shen tablets (one of the best-selling products of our Hutchison Baiyunshan joint venture) and other products with a pre-defined price range. The competitive bidding in effect sets price ceilings for those products, thereby limiting our profitability.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs which may affect reimbursement rates of our drug candidates if approved. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or the Affordable Care Act, was passed, which substantially changes the way health care is financed by both governmental and private insurers. The Affordable Care Act, among other things, establishes a new Medicare Part D coverage gap discount program, in which, effective 2019, manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D. In addition, other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted.

Modifications to or repeal of all or certain provisions of the Healthcare Reform Act had been expected based on statements made by President Donald Trump and certain members of Congress. However, we cannot predict the ultimate content, timing or effect of any changes to the Healthcare Reform Act or other federal and state reform efforts. There is no assurance that federal or state health care reform will not adversely affect our future business and financial results. We expect that additional U.S. state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our drug candidates or additional pricing pressures. We expect that the pharmaceutical industry will experience pricing pressures due to the increasing influence of managed care (and related implementation of managed care strategies to control utilization), additional federal and state legislative and regulatory proposals to regulate pricing of drugs, limit coverage of drugs or reduce reimbursement for drugs, public scrutiny and the Trump administration’s agenda to control the price of pharmaceuticals through government negotiations of drug prices in Medicare Part D and importation of cheaper products from abroad.

Moreover, eligibility for reimbursement in the United States does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim U.S. reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by U.S. government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Third-party payors in the United States often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved drugs that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize drugs and our overall financial condition.

Sales of products sold by our Prescription Drugs business rely on the ability to win tender bids for the medicine purchases of hospitals in China.

Our Commercial Platform’s Prescription Drugs business markets to hospitals in China who may make bulk purchases of a medicine only if that medicine is selected under a government-administered tender process. Periodically, a bidding process is organized on a provincial or municipal basis. Whether a drug manufacturer is invited to participate in the tender depends on the level of interest that hospitals have in purchasing this drug. The interest of a hospital in a medicine is evidenced by:

● the inclusion of this medicine on the hospital’s formulary, which establishes the scope of drug physicians at this hospital may prescribe to their patients, and

● the willingness of physicians at this hospital to prescribe a particular drug to their patients.

28

We believe that effective marketing efforts are critical in making and keeping hospitals interested in purchasing the Prescription Drugs sold through our Commercial Platform so that we and our joint ventures are invited to submit the products to the tender. Even if we and our joint ventures are invited to do so, competitors may be able to substantially reduce the price of their products or services. If competitors are able to offer lower prices, our and our joint ventures’ ability to win tender bids during the hospital tender process will be materially affected, and could reduce our total revenue or decrease our profit.

In 2018, China enacted a regulatory reform initiative bidding process in several cities. The initiative is aimed at driving consolidation in the fragmented generic prescription drug market in China. Under this program, major cities bulk-buy certain generic drugs together, forcing companies to bid for contracts and driving down prices. The system expanded nationwide to cover more cities and drugs in 2019. The system may reduce our Commercial Platform’s product portfolio as some of our third-party generic drug partners may fail to win bids.

Counterfeit products in China could negatively impact our revenue, brand reputation, business and results of operations.

Our Commercial Platform’s products are subject to competition from counterfeit products, especially counterfeit pharmaceuticals which are manufactured without proper licenses or approvals and are fraudulently mislabeled with respect to their content and/or manufacturer. Counterfeiters may illegally manufacture and market products under our or our joint venture’s brand names, the brand names of the third-party products we or they sell, or those of our or their competitors. Counterfeit pharmaceuticals are generally sold at lower prices than the authentic products due to their low production costs, and in some cases are very similar in appearance to the authentic products. Counterfeit pharmaceuticals may or may not have the same chemical content as their authentic counterparts. If counterfeit pharmaceuticals illegally sold under our or our joint ventures’ brand names or the brand names of third-party products we or they sell result in adverse side effects to consumers, we or our joint ventures may be associated with any negative publicity resulting from such incidents. In addition, consumers may buy counterfeit pharmaceuticals that are in direct competition with the products sold through our Commercial Platform, which could have an adverse impact on our revenue, business and results of operations. The proliferation of counterfeit pharmaceuticals in China and globally may grow in the future. Any such increase in the sales and production of counterfeit pharmaceuticals in China, or the technological capabilities of the counterfeiters, could negatively impact our revenue, brand reputation, business and results of operations.

Rapid changes in the pharmaceutical industry may render our Commercial Platform’s current products or our drug candidates obsolete.

Future technological improvements by our competitors and continual product developments in the pharmaceutical market may render our and our joint ventures’ existing products, our or their third-party licensed products or our drug candidates obsolete or affect our Commercial Platform’s viability and competitiveness. Therefore, our Commercial Platform’s future success will largely depend on our and our joint ventures’ ability to:

● improve existing products;

● develop innovative drug candidates;

● diversify the product and drug candidate portfolio;

● license diverse third-party products; and

● develop new and competitively priced products which meet the requirements of the constantly changing market.

If we or our joint ventures fail to respond to this environment by improving our Commercial Platform’s existing products, licensing new third-party products or developing new drug candidates in a timely fashion, or if such new or improved products do not achieve adequate market acceptance, our business and profitability may be materially and adversely affected.

29

Our Commercial Platform’s principal products involve the cultivation or sourcing of key raw materials including botanical products, and any quality control or supply failure or price fluctuations could adversely affect our Commercial Platform’s ability to manufacture our products and/or could materially and adversely affect our operating results.

The key raw materials used in the manufacturing process of certain of our Commercial Platform’s principal products are medicinal herbs whose properties are related to the regions and climatic conditions in which they are grown. Access to quality raw materials and products necessary for the manufacture of our Commercial Platform products is not guaranteed. We rely on a combination of materials grown by our or our joint ventures’ entities and materials sourced from third-party growers and suppliers. The availability, quality and prices of these raw materials are dependent on and closely affected by weather conditions and other seasonal factors which have an impact on the yields of the harvests each year. The quality, in some instances, also depends on the operations of third-party growers or suppliers. There is a risk that such growers or suppliers sell or attempt to sell us or our joint ventures raw materials which are not authentic. If there is any supply interruption for an indeterminate period of time, our joint ventures may not be able to identify and obtain alternative supplies that comply with our quality standards in a timely manner. Any supply disruption could adversely affect our ability to satisfy demand for our products, and materially and adversely affect our product sales and operating results. Moreover, any use by us or our joint ventures of unauthentic materials illegally sold to us by third-party growers or suppliers in our or our joint ventures’ products may result in adverse side effects to the consumers, negative publicity, or product liability claims against us or our joint ventures, any of which may materially and adversely affect our operating results.

The prices of necessary raw materials and products may be subject to price fluctuations according to market conditions, and any sudden increases in demand in the case of a widespread illness such as Covid-19, SARS, MERS or avian flu may impact the costs of production. For example, the market price of Sanqi, one of the main natural raw materials in Hutchison Baiyunshan’s Fu Fang Dan Shen tablets, fluctuated significantly between 2009 and 2019. Our Commercial Platform sources Sanqi and other necessary raw materials on a purchase order basis and does not have long-term supply contracts in place so that it can manage inventory levels to reduce its risk to price fluctuations; however, we cannot guarantee that we or our joint ventures will be successful in doing so. Raw material price fluctuations could increase the cost to manufacture our Commercial Platform’s products and adversely affect our operating results.

Adverse publicity associated with our company, our joint ventures or our or their products or third-party licensed products or similar products manufactured by our competitors could have a material adverse effect on our results of operations.

Sales of the Commercial Platform’s products are highly dependent upon market perceptions of the safety and quality of our and our joint ventures’ products and the third-party products we and they distribute. Concerns over the safety of biopharmaceutical products manufactured in China could have an adverse effect on the reputation of our industry and the sale of such products, including products manufactured or distributed by us and our joint ventures.

We could be adversely affected if any of our or our joint ventures’ products, third-party licensed products or any similar products manufactured by other companies prove to be, or are alleged to be, harmful to patients. Any negative publicity associated with severe adverse reactions or other adverse effects resulting from patients’ use or misuse of our and our joint ventures’ products or any similar products manufactured by other companies could also have a material adverse impact on our results of operations. We and our joint ventures have not, to date, experienced any significant quality control or safety problems. If in the future we or our joint ventures become involved in incidents of the type described above, such problems could severely and adversely impact our financial position and reputation.

We are dependent on our joint ventures’ production facilities in Shanghai, Guangzhou and Bozhou, China for the manufacture of our principal Commercial Platform products.

The principal products sold by our Commercial Platform are mainly produced or expected to be produced at our joint ventures’ manufacturing facilities in Shanghai, Guangzhou and Bozhou, China. A significant disruption at those facilities, even on a short-term basis, could impair our joint ventures’ ability to timely produce and ship products, which could have a material adverse effect on our business, financial position and results of operations.

30

Our joint ventures’ manufacturing operations are vulnerable to interruption and damage from natural and other types of disasters, including earthquake, fire, floods, environmental accidents, power loss, communications failures and similar events. If any disaster were to occur, our ability to operate our or our joint ventures’ business at these facilities would be materially impaired. In addition, the nature of our production and research activities could cause significant delays in our programs and make it difficult for us to recover from a disaster. We and our joint ventures maintain insurance for business interruptions to cover some of our potential losses; however, such disasters could still disrupt our operations and thereby result in substantial costs and diversion of resources.

In addition, our and our joint ventures’ production process requires a continuous supply of electricity. We and they have encountered power shortages historically due to restricted power supply to industrial users during summers when the usage of electricity is high and supply is limited or as a result of damage to the electricity supply network. Because the duration of those power shortages was brief, they had no material impact on our or their operations. Interruptions of electricity supply could result in lengthy production shutdowns, increased costs associated with restarting production and the loss of production in progress. Any major suspension or termination of electricity or other unexpected business interruptions could have a material adverse impact on our business, financial condition and results of operations.

Risks Relating to Our Dependence on Third Parties

Disagreements with our current or future collaboration partners, the amendment of any collaboration agreement or the termination of any collaboration arrangement, could cause delays in our product development and materially and adversely affect our business.

Our collaborations, including those with our oncology drug partners AstraZeneca and Eli Lilly, and any future collaborations that we enter into may not be successful. Disagreements between parties to a collaboration arrangement regarding clinical development and commercialization matters can lead to delays in the development process or commercializing the applicable drug candidate and, in some cases, termination of the collaboration arrangement. In addition, we or our partners may seek to amend the terms of one or more our collaboration agreements to adjust, among other things, the respective roles of our company and our collaboration partner as circumstances change. Our interests may not always be aligned with those of our collaboration partners, For instance, we are much smaller than our collaboration partners and because they or their affiliates may sell competing products. This may result in potential conflicts between our collaborators and us on matters that we may not be able to resolve on favorable terms or at all.

Collaborations with pharmaceutical or biotechnology companies and other third parties, including our existing agreements with AstraZeneca and Eli Lilly, are often terminable by the other party for any reason with certain advance notice. Any such termination or expiration would adversely affect us financially and could harm our business reputation. For instance, in the event one of the strategic alliances with a current collaborator is terminated, we may require significant time and resources to secure a new collaboration partner, if we are able to secure such an arrangement at all. As noted in the following risk factor, establishing new collaboration arrangements can be challenging and time-consuming. The loss of existing or future collaboration arrangements would not only delay or potentially terminate the possible development or commercialization of products we may derive from our technologies, but it may also delay or terminate our ability to test specific target candidates.

We rely on our collaborations with third parties for certain of our drug development activities, and, if we are unable to establish new collaborations when desired on commercially attractive terms or at all, we may have to alter our development and commercialization plans.

Certain of our drug development programs and the potential commercialization of certain drug candidates rely on collaborations, such as savolitinib with AstraZeneca and fruquintinib with Eli Lilly. In the future, we may decide to collaborate with additional pharmaceutical and biotechnology companies for the development and potential commercialization of our other drug candidates.

31

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA, NMPA or similar regulatory authorities outside the United States and China, the potential market for the subject drug candidate, the costs and complexities of manufacturing and delivering such drug candidate to patients, the potential of competing drugs, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally. The collaborator may also consider alternative drug candidates or technologies for similar indications that may be available to collaborate on and whether such collaboration could be more attractive than the one with us for our drug candidate. The terms of any additional collaboration or other arrangements that we may establish may not be favorable to us.

We may also be restricted under existing collaboration agreements from entering into future agreements on certain terms with potential collaborators. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

We may not be able to negotiate additional collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of the drug candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our drug candidates or bring them to market and generate drug revenue.

Further development and commercialization of our own drug candidates will depend, in part, on strategic alliances with our collaborators. If our collaborators do not diligently pursue product development efforts, impeding our ability to collect milestone and royalty payments, our progress may be delayed and our revenue may be deferred.

We rely and expect to continue to rely, to some extent, on our collaborators to provide funding in support of our own independent research and pre-clinical and clinical testing. We do not currently possess the financial resources necessary to fully develop and commercialize each of our drug candidates or the resources or capabilities to complete the lengthy regulatory approval processes that may be required for our drug candidates. Therefore, we rely and plan to continue to rely on strategic alliances to financially help us develop and commercialize certain of our drug candidates. As a result, our success depends, in part, on our ability to collect milestone and royalty payments from our existing collaborators, including our oncology drug partners AstraZeneca and Eli Lilly, and potential new collaborators. To the extent our collaborators do not aggressively pursue drug candidates for which we are entitled to such payments or pursue such drug candidates ineffectively, we will fail to realize these significant revenue streams, which could have an adverse effect on our business and future prospects.

If the alliances we currently have with AstraZeneca and Eli Lilly, or future collaborators with whom we may engage, are unable or unwilling to advance our programs, or if they do not diligently pursue product development and product approval, this may slow our progress and delay potential milestone and royalty payments. Any such failure would have an adverse effect on our ability to collect key revenue streams and, for this reason, would adversely impact our business, financial position and prospects. Our collaborators may sub-license or abandon drug candidates or we may have disagreements with our collaborators, which would cause associated product development to slow or cease. There can be no assurance that our current strategic alliances will be successful, and we may require significant time to secure new strategic alliances because we need to effectively market the benefits of our technology to these future alliance partners, which may direct the attention and resources of our research and development personnel and management away from our primary business operations. Further, each strategic alliance arrangement will involve the negotiation of terms that may be unique to each collaborator. These business development efforts may not result in a strategic alliance or may result in unfavorable arrangements.

Under typical collaboration agreements, we would expect to receive revenue for our drug candidates based on achievement of specific development, sales or regulatory approval milestones, as well as royalties based on a percentage of sales of the commercialized products. Achieving these milestones will depend, in part, on the efforts of our partner as well as our own. If we, or any alliance partner, fail to meet specific milestones, then the strategic alliance may be terminated, which could reduce our revenue.

32

The third-party vendors upon whom we rely for the supply of the active pharmaceutical ingredient, drug product and drug substance used in our drug candidates are our sole source of supply, and the loss of any of these suppliers could significantly harm our business.

The active pharmaceutical ingredient, drug product and drug substance used in our drug candidates are supplied to us from third-party vendors. Our ability to successfully develop our drug candidates, and to ultimately supply our commercial drugs in quantities sufficient to meet the market demand, depends in part on our ability to obtain the active pharmaceutical ingredient, drug product and drug substance for these drugs in accordance with regulatory requirements and in sufficient quantities for commercialization and clinical testing. We contract with a single supplier to manufacture and supply us with the active pharmaceutical ingredient for fruquintinib for commercial purposes. In addition, we are in the process of engaging a second supplier of such active pharmaceutical ingredient and have already validated its current good manufacturing practice, or cGMP, production processes. We have not yet entered into any purchase or supply agreement with this second supplier, so we have not determined the pricing or other commercial terms of this relationship. Other than the foregoing, we do not currently have arrangements in place for a contingent or second-source supply of the active pharmaceutical ingredient for fruquintinib or any other active pharmaceutical ingredients, drug product or drug substance used in our drug candidates in the event any of our current suppliers of such active pharmaceutical ingredient, drug product and drug substance cease their operations for any reason, which may lead to an interruption in our production.

For all of our drug candidates, we aim to identify and qualify multiple manufacturers to provide such active pharmaceutical ingredient, drug product and drug substance prior to submission of an NDA to the FDA and/or NMPA. We are not certain, however, that our current suppliers will be able to meet our demand for their products, either because of the nature of our agreements with those suppliers, our limited experience with those suppliers or our relative importance as a customer to those suppliers. It may be difficult for us to assess their ability to timely meet our demand in the future based on past performance. While our suppliers have generally met our demand for their products on a timely basis in the past, they may subordinate our needs in the future to their other customers.

Establishing additional or replacement suppliers for the active pharmaceutical ingredient, drug product and drug substance used in our drug candidates, if required, may not be accomplished quickly. If we are able to find a replacement supplier, such replacement supplier would need to be qualified and may require additional regulatory approval, which could result in further delay. While we seek to maintain adequate inventory of the active pharmaceutical ingredient, drug product and drug substance used in our drug candidates, any interruption or delay in the supply of components or materials, or our inability to obtain such active pharmaceutical ingredient, drug product and drug substance from alternate sources at acceptable prices in a timely manner could impede, delay, limit or prevent our development efforts, which could harm our business, results of operations, financial condition and prospects.

We and our collaborators rely, and expect to continue to rely, on third parties to conduct certain of our clinical trials for our drug candidates. If these third parties do not successfully carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our drug candidates and our business could be harmed.

We do not have the ability to independently conduct large-scale clinical trials. We and our collaboration partners rely, and expect to continue to rely, on medical institutions, clinical investigators, contract laboratories and other third parties, such as CROs, to conduct or otherwise support certain clinical trials for our drug candidates. Nevertheless, we and our collaboration partners (as applicable) will be responsible for ensuring that each clinical trial is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and reliance on CROs will not relieve us of our regulatory responsibilities. For any violations of laws and regulations during the conduct of clinical trials for our drug candidates, we could be subject to warning letters or enforcement action that may include civil penalties up to and including criminal prosecution.

Although we or our collaboration partners design the clinical trials for our drug candidates, CROs conduct most of the clinical trials. As a result, many important aspects of our development programs, including their conduct and timing, are outside of our direct control. Our reliance on third parties to conduct clinical trials results in less control over the management of data developed through clinical trials than would be the case if we were relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties may:

● have staffing difficulties;

● fail to comply with contractual obligations;

● experience regulatory compliance issues;

33

● undergo changes in priorities or become financially distressed; or

● form relationships with other entities, some of which may be our competitors.

These factors may materially and adversely affect the willingness or ability of third parties to conduct our and our collaboration partners’ clinical trials and may subject us or them to unexpected cost increases that are beyond our or their control.

If any of our and our collaboration partners’ relationships with these third-party CROs terminate, we or they may not be able to enter into arrangements with alternative CROs on reasonable terms or at all. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, any clinical trials such CROs are associated with may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully commercialize our drug candidates. As a result, we believe that our financial results and the commercial prospects for our drug candidates in the subject indication would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We, our collaboration partners or our CROs may fail to comply with the regulatory requirements pertaining to clinical trials, which could result in fines, adverse publicity and civil or criminal sanctions.

We, our collaboration partners and our CROs are required to comply with regulations for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial patients are adequately informed of the potential risks of participating in clinical trials and their rights are protected. These regulations are enforced by the FDA, the NMPA and comparable foreign regulatory authorities for any drugs in clinical development. In the United States, the FDA regulates GCP through periodic inspections of clinical trial sponsors, principal investigators and trial sites. If we, our collaboration partners or our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require additional clinical trials before approving the marketing applications for the relevant drug candidate. We cannot assure you that, upon inspection, the FDA or other applicable regulatory authority will determine that any of the future clinical trials for our drug candidates will comply with GCPs. In addition, clinical trials must be conducted with drug candidates produced under applicable manufacturing regulations. Our failure or the failure of our collaboration partners or CROs to comply with these regulations may require us or them to repeat clinical trials, which would delay the regulatory approval process and could also subject us to enforcement action. We are also required to register applicable clinical trials and post certain results of completed clinical trials on a U.S. government-sponsored database, ClinicalTrials.gov, within certain timeframes. Failure to do so can result in fines, adverse publicity and civil sanctions.

Joint ventures form an important part of our Commercial Platform business, and our ability to manage and develop the businesses conducted by these joint ventures depends in part on our relationship with our joint venture partners.

We are party to joint venture agreements with each of Shanghai Pharmaceuticals, Guangzhou Baiyunshan, Sinopharm and Hain Celestial, which together form an important part of our Commercial Platform business. Under these arrangements, our joint venture partners have certain operational responsibilities and/or certain rights to exercise control or influence over operations and decision-making.

34

Our equity interests in these operating companies do not provide us with the ability to control actions which require shareholder approval. In addition, under the joint venture contracts for these entities, the consent of the directors nominated by our joint venture partners is required for the passing of resolutions in relation to certain matters concerning the operations of these companies. As a result, although we participate in the management, and in the case of Hutchison Sinopharm and Shanghai Hutchison Pharmaceuticals nominate the management and run the day-to-day operations, we may not be able to secure the consent of our joint venture partners to pursue activities or strategic objectives that are beneficial to or that facilitate our overall business strategies. With respect to Hutchison Baiyunshan, which is a jointly controlled and managed joint venture where we share the ability to appoint the general manager with our partner Guangzhou Baiyunshan, with each of us having a rotating four-year right, we rely on our relationship with our partner, and our ability to manage the day-to-day operations of this joint venture is more limited. To the extent Guangzhou Baiyunshan does not, for example, diligently perform its responsibilities with respect to any aspect of Hutchison Baiyunshan’s operations, agree with or cooperate in the implementation of any plans we may have for Hutchison Baiyunshan’s business in the future or take steps to ensure that Hutchison Baiyunshan is in compliance with applicable laws and regulations, our business and ability to comply with legal, regulatory and financial reporting requirements which will apply to us as a public company, as well as the results of this joint venture, could be materially and adversely affected. Furthermore, disagreements or disputes which arise between us and our joint venture partners may potentially require legal action to resolve and hinder the smooth operation of our Commercial Platform business or adversely affect our financial condition, results of operations and prospects.

We and our joint ventures rely on our distributors for logistics and distribution services for our Commercial Platform business.

We and our joint ventures rely on distributors to perform certain operational activities, including invoicing, logistics and delivery of the products we and they market to the end customers. Because we and our joint ventures rely on third-party distributors, we have less control than if we handled distribution logistics directly and can be adversely impacted by the actions of our distributors. Any disruption of our distribution network, including failure to renew existing distribution agreements with desired distributors, could negatively affect our ability to effectively sell our products and materially and adversely affect the business, financial condition and results of operations of us and our joint ventures.

There is no assurance that the benefits currently enjoyed by virtue of our association with CK Hutchison will continue to be available.

Historically, we have relied on the reputation and experience of, and support provided by, our founding shareholder, Hutchison Whampoa Limited (a wholly owned subsidiary of CK Hutchison), to advance our joint ventures and collaborations in China and elsewhere. CK Hutchison is a Hong Kong-based, multinational conglomerate with operations in over 50 countries. CK Hutchison is the ultimate parent company of Hutchison Healthcare Holdings Limited, which as of March 1, 2020, owns 48.2% of our total outstanding share capital. We believe that CK Hutchison group’s reputation in China has given us an advantage in negotiating collaborations and obtaining opportunities.

We also benefit from sharing certain services with the CK Hutchison group including, among others, legal and regulatory services, company secretarial support services, tax and internal audit services, shared use of accounting software system and related services, participation in the CK Hutchison group’s pension, medical and insurance plans, participation in the CK Hutchison group’s procurement projects with third-party vendors/suppliers, other staff benefits and staff training services, company functions and activities and operation advisory and support services. We pay a management fee to an affiliate of CK Hutchison for the provision of such services. In each of the years ended December 31, 2017, 2018 and 2019, we paid a management fee of approximately $897,000, $922,000 and $931,000, respectively. In addition, we benefit from the fact that two retail chains affiliated with the CK Hutchison group, PARKnSHOP and Watsons, sell certain of our Commercial Platform products in their stores throughout Hong Kong and in other Asian countries. For the years ended December 31, 2017, 2018 and 2019, sales of our products to members of the CK Hutchison group amounted to $8.5 million, $8.3 million and $7.6 million, respectively.

Our business also depends on certain intellectual property rights licensed to us by the CK Hutchison group. See “—Risks Relating to Intellectual Property—We and our joint ventures are dependent on trademark and other intellectual property rights licensed from others. If we lose our licenses for any of our products, we or our joint ventures may not be able to continue developing such products or may be required to change the way we market such products” for more information on risks associated with such intellectual property licensed to us.

There can be no assurance the CK Hutchison group will continue to provide the same benefits or support that they have provided to our business historically. Such benefit or support may no longer be available to us, in particular, if CK Hutchison’s ownership interest in our company significantly decreases in the future.

35

Other Risks and Risks Relating to Doing Business in China

Product liability claims or lawsuits could cause us or our joint ventures to incur substantial liabilities.

We and our joint ventures face an inherent risk of product liability exposure related to the use of our drug candidates in clinical trials, sales of our or our joint ventures’ products or the products we or they license from third parties through our Commercial Platform. If we and our joint ventures cannot successfully defend against claims that the use of such drug candidates in our clinical trials or any products sold through our Commercial Platform, including fruquintinib and/or any of our drug candidates which receive regulatory approval, caused injuries, we and our joint ventures could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

● decreased demand for products sold through our Commercial Platform;

● significant negative media attention and reputational damage;

● withdrawal of clinical trial participants;

● significant costs to defend the related litigation;

● substantial monetary awards to trial participants or patients;

● loss of revenue; and

● the inability to commercialize any drug candidates that we may develop.

Our principal insurance policies cover product liability for fruquintinib, property loss due to accidents or natural disasters and adverse events in clinical trials. Existing PRC laws and regulations do not require us or our joint ventures to have, nor do we or they, maintain liability insurance to cover product liability claims except with respect to fruquintinib. We and our joint ventures do not have business liability, or in particular, product liability for each of our drug candidates or certain of our or their products except with respect to fruquintinib. Any litigation might result in substantial costs and diversion of resources. While we and our joint ventures maintain liability insurance for certain clinical trials and products, this insurance may not fully cover our potential liabilities. Inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of products that we or our collaborators develop.

36

We and our joint ventures may be exposed to liabilities under the U.S. Foreign Corrupt Practices Act, or FCPA, the Bribery Act 2010 of the United Kingdom, or U.K. Bribery Act, and Chinese anti-corruption laws, and any determination that we have violated these laws could have a material adverse effect on our business or our reputation.

In the day-to-day conduct of our business, we and our joint ventures are in frequent contact with persons who may be considered government officials under applicable anti-corruption, anti-bribery and anti-kickback laws, which include doctors at public hospitals in China and elsewhere. Therefore, we and our joint ventures are subject to risk of violations under the FCPA, the U.K. Bribery Act, and other laws in the countries where we do business. We and our joint ventures have operations, agreements with third parties and we and our joint ventures make most of our sales in China. The PRC also strictly prohibits bribery of government officials. Our and our joint ventures’ activities in China create the risk of unauthorized payments or offers of payments by the directors, employees, representatives, distributors, consultants or agents of our company or our joint ventures, even though they may not always be subject to our control. It is our policy to implement safeguards to discourage these practices by our and our joint ventures’ employees. We have implemented and adopted policies designed by the R&D-based Pharmaceutical Association Committee, an industry association representing approximately 40 global biopharmaceutical companies, to ensure compliance by us and our joint ventures and our and their directors, officers, employees, representatives, distributors, consultants and agents with the anti-corruption laws and regulations. We cannot assure you, however, that our existing safeguards are sufficient or that our or our joint ventures’ directors, officers, employees, representatives, distributors, consultants and agents have not engaged and will not engage in conduct for which we may be held responsible, nor can we assure you that our business partners have not engaged and will not engage in conduct that could materially affect their ability to perform their contractual obligations to us or even result in our being held liable for such conduct. Violations of the FCPA, the U.K. Bribery Act or Chinese anti-corruption laws may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could have a material adverse effect on our business, reputation, financial condition, cash flows and results of operations.

Ensuring that our and our joint ventures’ future business arrangements with third parties comply with applicable laws could also involve substantial costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our or our joint ventures’ operations were found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment and exclusion from government funded healthcare programs, any of which could substantially disrupt our operations. If the physicians, hospitals or other providers or entities with whom we and our joint ventures do business are found not to be in compliance with applicable laws, they may also be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

If we or our joint ventures fail to comply with environmental, health and safety laws and regulations, we or they could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We and our joint ventures are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemical materials. Our operations also produce hazardous waste products. We and our joint ventures are therefore subject to PRC laws and regulations concerning the discharge of waste water, gaseous waste and solid waste during our manufacturing processes. We and our joint ventures are required to establish and maintain facilities to dispose of waste and report the volume of waste to the relevant government authorities, which conduct scheduled or unscheduled inspections of our facilities and treatment of such discharge. We and our joint ventures may not at all times comply fully with environmental regulations. Any violation of these regulations may result in substantial fines, criminal sanctions, revocations of operating permits, shutdown of our facilities and obligation to take corrective measures. We and our joint ventures generally contract with third parties for the disposal of these materials and waste. We and our joint ventures cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from the use of hazardous materials, we and/or our joint ventures could be held liable for any resulting damages, and any liability could exceed our resources. We and/or our joint ventures also could incur significant costs associated with civil or criminal fines and penalties.

37

Although we and our joint ventures maintain workers’ compensation insurance to cover costs and expenses incurred due to on-the-job injuries to our employees and third-party liability insurance for injuries caused by unexpected seepage, pollution or contamination, this insurance may not provide adequate coverage against potential liabilities. Furthermore, the PRC government may take steps towards the adoption of more stringent environmental regulations. Due to the possibility of unanticipated regulatory or other developments, the amount and timing of future environmental expenditures may vary substantially from those currently anticipated. If there is any unanticipated change in the environmental regulations, we and our joint ventures may need to incur substantial capital expenditures to install, replace, upgrade or supplement our equipment or make operational changes to limit any adverse impact or potential adverse impact on the environment in order to comply with new environmental protection laws and regulations. If such costs become prohibitively expensive, we may be forced to cease certain aspects of our or our joint ventures’ business operations.

We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cybersecurity incidents, could harm our ability to operate our business effectively.

We are heavily dependent on critical, complex and interdependent information technology systems, including internet-based systems, to support our business processes. Our information technology system security is continuously reviewed, maintained and upgraded in response to possible security breach incidents. Despite the implementation of these measures, our information technology systems and those of third parties with which we contract are vulnerable to damage from external or internal security incidents, breakdowns, malicious intrusions, cybercrimes, including State-sponsored cybercrimes, malware, misplaced or lost data, programming or human errors or other similar events. System failures, accidents or security breaches could cause interruptions in our operations and could result in inappropriately accessed, tampered with, modified or stolen scientific data or a material disruption of our clinical activities and business operations, in addition to possibly requiring substantial expenditures of resources to remedy. Such event could significantly harm our Innovation Platform’s operations, including resulting in the loss of clinical trial data which could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Such events could also lead to the loss of important information such as trade secrets or other intellectual property and could accelerate the development or manufacturing of competing products by third parties. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and our research and development programs and the development of our drug candidates could be delayed.

The PRC’s economic, political and social conditions, as well as governmental policies, could affect the business environment and financial markets in China, our ability to operate our business, our liquidity and our access to capital.

Substantially all of our and our joint ventures’ business operations are conducted in China. Accordingly, our results of operations, financial condition and prospects are subject to a significant degree to economic, political and legal developments in China. China’s economy differs from the economies of developed countries in many respects, including with respect to the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. While the PRC economy has experienced significant growth in the past 30 years, growth has been uneven across different regions and among various economic sectors of China. The PRC government has implemented various measures to encourage economic development and guide the allocation of resources. Some of these measures benefit the overall PRC economy, but may have a negative effect on us or our joint ventures. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us or our joint ventures. More generally, if the business environment in China deteriorates from the perspective of domestic or international investors, our or our joint ventures’ business in China may also be adversely affected.

38

The recent coronavirus Covid-19 outbreak and other adverse public health developments could materially and adversely affect our business.

In December 2019, an outbreak of a novel strain of coronavirus (Covid-19) was reported in Wuhan, China and has since spread throughout China and to other countries. The outbreak of Covid-19, if it continues to worsen, and other adverse public health developments could materially and adversely affect our business, financial condition and results of operations. Our operations have been, and may continue to be, impacted due to national and regional Chinese government declarations requiring closures, quarantines and travel restrictions. For instance, our clinical studies in China have encountered some limitations to patient visits for screening, treatment and clinical assessment. In addition, our prescription drug sales teams have seen some short-term limitations on conducting normal operations. The extent to which the coronavirus impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus, among others. If the severity and reach of the Covid-19 outbreak increases, there may be significant and material disruptions to normal operations, which may then have a material adverse effect on our operations, operating results and financial condition.

Uncertainties with respect to the PRC legal system and changes in laws, regulations and policies in China could materially and adversely affect us.

We conduct our business primarily through our subsidiaries and joint ventures in China. PRC laws and regulations govern our and their operations in China. Our subsidiaries and joint ventures are generally subject to laws and regulations applicable to foreign investments in China, which may not sufficiently cover all of the aspects of our or their economic activities in China. In particular, some laws, particularly with respect to drug price reimbursement, are relatively new, and because of the limited volume of published judicial decisions and their non-binding nature, the interpretation and enforcement of these laws and regulations are uncertain. Furthermore, recent regulatory reform in the China pharmaceutical industry will limit the number of distributors allowed between a manufacturer and each hospital to one, which may limit the rate of sales growth of Hutchison Sinopharm in future periods. In addition, the implementation of laws and regulations may be in part based on government policies and internal rules that are subject to the interpretation and discretion of different government agencies (some of which are not published on a timely basis or at all) that may have a retroactive effect. As a result, we may not be aware of our, our collaboration partners’ or our joint ventures’ violation of these policies and rules until sometime after the violation. In addition, any litigation in China, regardless of outcome, may be protracted and result in substantial costs and diversion of resources and management attention.

For further information regarding government regulation in China and other jurisdictions, see Item 4.B. “Business Overview—Regulation—Government Regulation of Pharmaceutical Product Development and Approval—PRC Regulation of Pharmaceutical Product Development and Approval,” “Business Overview—Regulation—Coverage and Reimbursement—PRC Coverage and Reimbursement” and “Business Overview—Regulation—Other Healthcare Laws—Other PRC Healthcare Laws.”

Restrictions on currency exchange may limit our ability to receive and use our revenue effectively.

Substantially all of our revenue is denominated in renminbi, which currently is not a freely convertible currency. A portion of our revenue may be converted into other currencies to meet our foreign currency obligations, including, among others, payments of dividends declared, if any, in respect of our ordinary shares or ADSs. Under China’s existing foreign exchange regulations, our subsidiaries and joint ventures are able to pay dividends in foreign currencies or convert renminbi into other currencies for use in operations without prior approval from the PRC State Administration of Foreign Exchange, or the SAFE, by complying with certain procedural requirements. However, we cannot assure you that the PRC government will not take future measures to restrict access to foreign currencies for current account transactions.

39

Our PRC subsidiaries’ and joint ventures’ ability to obtain foreign exchange is subject to significant foreign exchange controls and, in the case of amounts under the capital account, requires the approval of and/or registration with PRC government authorities, including the SAFE. In particular, if we finance our PRC subsidiaries or joint ventures by means of foreign debt from us or other foreign lenders, the amount is not allowed to exceed either the cross-border financing risk weighted balance calculated based on a formula by the PBOC or the difference between the amount of total investment and the amount of the registered capital as acknowledged by the Ministry of Commerce, or MOFCOM, and the SAFE. Further, such loans must be filed with and registered with the SAFE or their local branches and the National Development and Reform Commission (if applicable). If we finance our PRC subsidiaries or joint ventures by means of additional capital contributions, the amount of these capital contributions must first be filed with the relevant government approval authority. These limitations could affect the ability of our PRC subsidiaries and joint ventures to obtain foreign exchange through debt or equity financing.

Our business benefits from certain PRC government tax incentives. The expiration of, changes to, or our PRC subsidiaries/joint ventures failing to continuously meet the criteria for these incentives could have a material adverse effect on our operating results by significantly increasing our tax expenses.

Certain of our PRC subsidiaries and joint ventures have been granted High and New Technology Enterprise, or HNTE, status by the relevant PRC authorities. This status allows the relevant enterprise to enjoy a reduced Enterprise Income Tax, or EIT, rate at 15% on its taxable profits. For the duration of its HNTE grant, the relevant PRC enterprise must continue to meet the relevant HNTE criteria or else the 25% standard EIT rate will be applied from the beginning of the calendar year when the enterprise fails to meet the relevant criteria. We are in the process of renewing for HNTE status which expired at the end of 2019 for certain of our PRC subsidiaries and joint ventures. It is unclear whether the HNTE status and tax incentives under the current policy will continue to be granted after their expiration dates. If the rules for such incentives are amended or the status is not renewed, higher EIT rates may apply resulting in increased tax burden which will impact our business, financial condition, results of operations and growth prospects.

We may be treated as a resident enterprise for PRC Tax purposes under China’s Enterprise Income Tax Law and Implementation Rules, effective as of January 1, 2008, or the EIT Law, and our global income may therefore be subject to PRC income tax.

China’s EIT Law defines the term “de facto management bodies” as “bodies that substantially carry out comprehensive management and control on the business operation, employees, accounts and assets of enterprises.” Under the EIT Law, an enterprise incorporated outside of China whose “de facto management bodies” are located in China is considered a “resident enterprise” and will be subject to a uniform 25% EIT rate on its global income. On April 22, 2009, China’s State Administration of Taxation, or the SAT, in the Notice Regarding the Determination of Chinese-Controlled Offshore-Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies, or Circular 82, further specified certain criteria for the determination of what constitutes “de facto management bodies.” If all of these criteria are met, the relevant foreign enterprise may be regarded to have its “de facto management bodies” located in China and therefore be considered a resident enterprise in China. These criteria include: (i) the enterprise’s day-to-day operational management is primarily exercised in China; (ii) decisions relating to the enterprise’s financial and human resource matters are made or subject to approval by organizations or personnel in China; (iii) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholders’ meeting minutes are located or maintained in China; and (iv) 50% or more of voting board members or senior executives of the enterprise habitually reside in China. Although Circular 82 only applies to foreign enterprises that are majority-owned and controlled by PRC enterprises, not those owned and controlled by foreign enterprises or individuals, the determining criteria set forth in Circular 82 may be adopted by the PRC tax authorities as the test for determining whether the enterprises are PRC tax residents, regardless of whether they are majority-owned and controlled by PRC enterprises.

Except for our PRC subsidiaries and joint ventures incorporated in China, we believe that none of our entities incorporated outside of China is a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities, and uncertainties remain with respect to the interpretation of the term “de facto management body.”

If we are treated as a PRC tax resident, dividends distributed by us to our non-PRC shareholders and ADS holders or any gains realized by non-PRC shareholders and ADS holders from the transfer of our shares or ADSs may be subject to PRC tax.

Under the EIT Law, dividends payable by a PRC enterprise to its foreign investor who is a non-PRC resident enterprise, as well as gains on transfers of shares of a PRC enterprise by such a foreign investor will generally be subject to a 10% withholding tax, unless such non-PRC resident enterprise’s jurisdiction of tax residency has an applicable tax treaty with the PRC that provides for a reduced rate of withholding tax.

40

If the PRC tax authorities determine that we should be considered a PRC resident enterprise for EIT purposes, any dividends payable by us to our non-PRC resident enterprise shareholders or ADS holders, as well as gains realized by such investors from the transfer of our shares or ADSs may be subject to a 10% withholding tax, unless a reduced rate is available under an applicable tax treaty. Furthermore, if we are considered a PRC resident enterprise for EIT purposes, it is unclear whether our non-PRC individual shareholders (including our ADS holders) would be subject to any PRC tax on dividends or gains obtained by such non-PRC individual shareholders. If any PRC tax were to apply to dividends or gains realized by non-PRC individuals, it would generally apply at a rate of up to 20% unless a reduced rate is available under an applicable tax treaty. If dividends payable to our non-PRC resident shareholders, or gains from the transfer of our shares or ADSs by such shareholders are subject to PRC tax, the value of your investment in our shares or ADSs may decline significantly.

There is uncertainty regarding the PRC withholding tax rate that will be applied to distributions from our PRC subsidiaries and joint ventures to their respective Hong Kong immediate holding companies, which could have a negative impact on our business.

The EIT Law provides that a withholding tax at the rate of 10% is applicable to dividends payable by a PRC resident enterprise to investors who are “non-resident enterprises” (i.e., that do not have an establishment or place of business in the PRC or that have such establishment or place of business but the relevant dividend is not effectively connected with the establishment or place of business). However, pursuant to the Arrangement between the Mainland of China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income, or the Arrangement, withholding tax at a reduced rate of 5% may be applicable to dividends payable by PRC resident enterprises to beneficial owners of the dividends that are Hong Kong tax residents if certain requirements are met. There is uncertainty regarding whether the PRC tax authorities will consider us to be eligible to the reduced tax rate. If the Arrangement is deemed not to apply to dividends payable by our PRC subsidiaries and joint ventures to their respective Hong Kong immediate holding companies that are ultimately owned by us, the withholding tax rate applicable to us will be the statutory rate of 10% instead of 5% which may potentially impact our business, financial condition, results of operations and growth prospects.

We may be treated as a resident enterprise for U.K. corporate tax purposes, and our global income may therefore be subject to U.K. corporation tax.

U.K. resident companies are taxable in the United Kingdom on their worldwide profits. A company incorporated outside of the United Kingdom would be regarded as a resident if its central management and control resides in the United Kingdom. The place of central management and control generally means the place where the high-level strategic decisions of a company are made.

We are an investment holding company incorporated in the Cayman Islands and are admitted to trading on the AIM market of the London Stock Exchange. Our central management and control resides in Hong Kong, and therefore we believe that we are not a U.K. resident for corporate tax purposes. However, the tax resident status of a non-resident entity could be challenged by the U.K. tax authorities.

If the U.K. tax authorities determine that we are a U.K. tax resident, our profits will be subject to U.K. Corporation Tax rate at 19%, subject to the potential availability of certain exemptions related to dividend income and capital gains. This may have a material adverse effect on our financial condition and results of operations.

Any failure to comply with PRC regulations regarding our employee equity incentive plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions, which could adversely affect our business, financial condition and results of operations.

In February 2012, the SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly Listed Companies. Based on this regulation, PRC residents who are granted shares or share options by a company listed on an overseas stock market under its employee share option or share incentive plan are required to register with the SAFE or its local counterparts by following certain procedures. We and our employees who are PRC residents and individual beneficial owners who have been granted shares or share options have been subject to these rules due to our listing on the AIM market of the London Stock Exchange and Nasdaq. We have registered the option schemes and the share incentive plan and will continue to assist our employees to register their share options or shares. However, any failure of our PRC individual beneficial owners and holders of share options or shares to comply with the SAFE registration requirements in the future may subject them to fines and legal sanctions and may, in rare instances, limit the ability of our PRC subsidiaries to distribute dividends to us.

41

In addition, the SAT has issued circulars concerning employee share options or restricted shares. Under these circulars, employees working in the PRC who exercise share options, or whose restricted shares vest, will be subject to PRC individual income tax, or IIT. The PRC subsidiaries of an overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold IIT of those employees related to their share options or restricted shares. Although the PRC subsidiaries currently withhold IIT from the PRC employees in connection with their exercise of share options, if they fail to report and pay the tax withheld according to relevant laws, rules and regulations, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities.

We may be involved in litigation, legal disputes, claims or administrative proceedings which could be costly and time-consuming to resolve.

We may become subject, from time to time, to legal proceedings and claims that arise in the ordinary course of business or pursuant to governmental or regulatory enforcement activity. Any litigation or proceeding to which we become a party might result in substantial costs and divert management’s attention and resources. Furthermore, any litigation, legal disputes, claims or administrative proceedings which are initially not of material importance may escalate and become important to us due to a variety of factors, such as changes in the facts and circumstances of the cases, the likelihood of loss, the monetary amount at stake and the parties involved. Our insurance might not cover claims brought against us, provide sufficient payments to financially cover all of the costs to resolve such claims or continue to be available on terms acceptable to us.

Risks Relating to Intellectual Property

If we, our joint ventures or our collaboration partners are unable to protect our or their products and drug candidates through intellectual property rights, our competitors may compete directly against us or them.

Our success depends, in part, on our, our joint venture partners’ and our collaboration partners’ ability to protect our and our joint ventures’ and our collaboration partners’ products and drug candidates from competition by establishing, maintaining and enforcing our or their intellectual property rights. We, our joint ventures and our collaboration partners seek to protect the products and technology that we and they consider commercially important by filing PRC and international patent applications, relying on trade secrets or pharmaceutical regulatory protection or employing a combination of these methods. As of December 31, 2019, we had 208 issued patents, including 22 Chinese patents, 21 U.S. patents and 11 European patents, 137 patent applications pending in the above major market jurisdictions, and five pending Patent Cooperation Treaty, or PCT, patent applications relating to the drug candidates of our Innovation Platform. Our collaboration partner AstraZeneca is responsible for maintaining and enforcing our intellectual property rights in relation to savolitinib. Additionally, our joint ventures collectively had 127 issued patents and 36 patent applications in China and other jurisdictions relating to our Commercial Platform’s products as of December 31, 2019. For more details, see Item 4.B. “Business Overview—Patents and Other Intellectual Property.” Patents may become invalid and patent applications may not be granted for a number of reasons, including known or unknown prior art, deficiencies in the patent application or the lack of originality of the technology. In addition, the PRC and the United States have adopted the “first-to-file” system under which whoever first files an invention patent application will be awarded the patent. Under the first-to-file system, third parties may be granted a patent relating to a technology which we invented. Furthermore, the terms of patents are finite. The patents we hold and patents to be issued from our currently pending patent applications generally have a twenty-year protection period starting from the date of application.

We, our joint ventures and/or our collaboration partners may become involved in patent litigation against third parties to enforce our or their patent rights, to invalidate patents held by such third parties, or to defend against such claims. A court may refuse to stop the other party from using the technology at issue on the grounds that our or our joint ventures’ patents do not cover the third-party technology in question. Further, such third parties could counterclaim that we or our joint ventures infringe their intellectual property or that a patent we, our joint ventures or our collaboration partners have asserted against them is invalid or unenforceable. In patent litigation, defendant counterclaims challenging the validity, enforceability or scope of asserted patents are commonplace. In addition, third parties may initiate legal proceedings against us or our intellectual property to assert such challenges to our intellectual property rights.

42

The outcome of any such proceeding is generally unpredictable. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Patents may be unenforceable if someone connected with prosecution of the patent withheld relevant information or made a misleading statement during prosecution. It is possible that prior art of which we, our joint ventures or our collaboration partners and the patent examiner were unaware during prosecution exists, which could render our or their patents invalid. Moreover, it is also possible that prior art may exist that we, our joint ventures or our collaboration partners are aware of but do not believe is relevant to our or their current or future patents, but that could nevertheless be determined to render our patents invalid. The cost to us or our joint ventures of any patent litigation or similar proceeding could be substantial, and it may consume significant management time. We and our joint ventures do not maintain insurance to cover intellectual property infringement.

An adverse result in any litigation proceeding could put one or more of our or our joint ventures’ patents at risk of being invalidated or interpreted narrowly. If a defendant were to prevail on a legal assertion of invalidity or unenforceability of our patents covering one of our or our joint ventures’ products or our drug candidates, we could lose at least part, and perhaps all, of the patent protection covering such product or drug candidate. Competing drugs may also be sold in other countries in which our or our joint ventures’ patent coverage might not exist or be as strong. If we lose a foreign patent lawsuit, alleging our or our joint ventures’ infringement of a competitor’s patents, we could be prevented from marketing our drugs in one or more foreign countries. Any of these outcomes would have a materially adverse effect on our business.

Intellectual property and confidentiality legal regimes in China may not afford protection to the same extent as in the United States or other countries. Implementation and enforcement of PRC intellectual property laws may be deficient and ineffective. Policing unauthorized use of proprietary technology is difficult and expensive, and we or our joint ventures may need to resort to litigation to enforce or defend patents issued to us or them or to determine the enforceability, scope and validity of our proprietary rights or those of others. The experience and capabilities of PRC courts in handling intellectual property litigation varies, and outcomes are unpredictable. Further, such litigation may require a significant expenditure of cash and may divert management’s attention from our or our joint ventures’ operations, which could harm our business, financial condition and results of operations. An adverse determination in any such litigation could materially impair our or our joint ventures’ intellectual property rights and may harm our business, prospects and reputation.

Developments in patent law could have a negative impact on our business.

From time to time, authorities in the United States, China and other government authorities may change the standards of patentability, and any such changes could have a negative impact on our business.

For example, in the United States, the Leahy-Smith America Invents Act, or the America Invents Act, which was signed into law in 2011, includes a number of significant changes to U.S. patent law. These changes include a transition from a “first-to-invent” system to a “first-to-file” system, changes to the way issued patents are challenged, and changes to the way patent applications are disputed during the examination process. As a result of these changes, patent law in the United States may favor larger and more established companies that have greater resources to devote to patent application filing and prosecution. The U.S. Patent and Trademark Office, or USPTO, has developed new and untested regulations and procedures to govern the full implementation of the America Invents Act, and many of the substantive changes to patent law associated with the America Invents Act, and, in particular, the first-to-file provisions became effective on March 16, 2013. Substantive changes to patent law associated with the America Invents Act may affect our ability to obtain patents, and if obtained, to enforce or defend them. Accordingly, it is not clear what, if any, impact the America Invents Act will have on the cost of prosecuting our or our joint ventures’ patent applications and our or their ability to obtain patents based on our or our joint ventures’ discoveries and to enforce or defend any patents that may issue from our or their patent applications, all of which could have a material adverse effect on our business.

43

If we are unable to maintain the confidentiality of our and our joint ventures’ trade secrets, the business and competitive position of ourselves and our joint ventures may be harmed.

In addition to the protection afforded by patents and the PRC’s State Secret certification, we and our joint ventures rely upon unpatented trade secret protection, unpatented know-how and continuing technological innovation to develop and maintain our competitive position. We seek to protect our and our joint ventures’ proprietary technology and processes, in part, by entering into confidentiality agreements with our and their collaborators, scientific advisors, employees and consultants, and invention assignment agreements with our and their consultants and employees. We and our joint ventures may not be able to prevent the unauthorized disclosure or use of our or their technical know-how or other trade secrets by the parties to these agreements, however, despite the existence generally of confidentiality agreements and other contractual restrictions. If any of the collaborators, scientific advisors, employees and consultants who are parties to these agreements breaches or violates the terms of any of these agreements, we and our joint ventures may not have adequate remedies for any such breach or violation, and we could lose our trade secrets as a result. Enforcing a claim that a third-party illegally obtained and is using our or our joint ventures’ trade secrets, like patent litigation, is expensive and time consuming, and the outcome is unpredictable. In addition, courts in China and other jurisdictions outside the United States are sometimes less prepared or willing to protect trade secrets.

Our and our joint ventures’ trade secrets could otherwise become known or be independently discovered by our or their competitors. For example, competitors could purchase our drugs and attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, design around our protected technology or develop their own competitive technologies that fall outside of our intellectual property rights. If any of our or our joint ventures’ trade secrets were to be lawfully obtained or independently developed by a competitor, we and our joint ventures would have no right to prevent them, or others to whom they communicate it, from using that technology or information to compete against us or our joint ventures. If our or our joint ventures’ trade secrets are unable to adequately protect our business against competitors’ drugs, our competitive position could be adversely affected, as could our business.

We and our joint ventures are dependent on trademark and other intellectual property rights licensed from others. If we lose our licenses for any of our products, we or our joint ventures may not be able to continue developing such products or may be required to change the way we market such products.

We and our joint ventures are parties to licenses that give us or them rights to third-party intellectual property that are necessary or useful for our or our joint ventures’ businesses. In particular, the “Hutchison,” “Chi-Med” and “China-MediTech” brands, among others, have been licensed to us by Hutchison Whampoa Enterprises Limited, an affiliate of our largest shareholder, Hutchison Healthcare Holdings Limited. Hutchison Whampoa Enterprises Limited grants us a royalty-free, worldwide license to such brands. Under the terms of our brand license agreement, Hutchison Whampoa Enterprises Limited has the right to terminate the license if, among other things, we commit a material breach of the agreement, or within any twelve-month period the aggregate direct or indirect shareholding in our company held by CK Hutchison is reduced to less than 40%, 30% or 20%. In addition, the “Baiyunshan” brand, which is a key brand used by Hutchison Baiyunshan on its products, has been licensed to Hutchison Baiyunshan by our joint venture partner, Guangzhou Baiyunshan, for use during the 50-year joint venture period; however, Guangzhou Baiyunshan has the right to terminate the license if its interest in Hutchison Baiyunshan falls below 50%. If any such license is terminated, our or Hutchison Baiyunshan’s business, and our or their positioning in the Chinese market and our financial condition, results of operations and prospects may be materially and adversely affected.

In some cases, our licensors have retained the right to prosecute and defend the intellectual property rights licensed to us or our joint ventures. We depend in part on the ability of our licensors to obtain, maintain and enforce intellectual property protection for such licensed intellectual property. Such licensors may not successfully maintain their intellectual property, may determine not to pursue litigation against other companies that are infringing on such intellectual property, or may pursue litigation less aggressively than we or our joint ventures would. Without protection for the intellectual property we or our joint ventures license, other companies might be able to offer substantially identical products or branding, which could adversely affect our competitive business position and harm our business prospects.

44

If our or our joint ventures’ products or drug candidates infringe the intellectual property rights of third parties, we and they may incur substantial liabilities, and we and they may be unable to sell these products.

Our commercial success depends significantly on our and our joint ventures’ ability to operate without infringing the patents and other proprietary rights of third parties. In the PRC, invention patent applications are generally maintained in confidence until their publication 18 months from the filing date. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the underlying discoveries were made and invention patent applications are filed. Even after reasonable investigation, we may not know with certainty whether any third-party may have filed a patent application without our knowledge while we or our joint ventures are still developing or producing that product. While the success of pending patent applications and applicability of any of them to our or our joint ventures’ programs are uncertain, if asserted against us or them, we could incur substantial costs and we or they may have to:

● obtain licenses, which may not be available on commercially reasonable terms, if at all;

● redesign products or processes to avoid infringement; and

● stop producing products using the patents held by others, which could cause us or them to lose the use of one or more of our or their products.

To date, we and our joint ventures have not received any material claims of infringement by any third parties. If a third-party claims that we or our joint ventures infringe its proprietary rights, any of the following may occur:

● we or our joint ventures may have to defend litigation or administrative proceedings that may be costly whether we or they win or lose, and which could result in a substantial diversion of management resources;

● we or our joint ventures may become liable for substantial damages for past infringement if a court decides that our technology infringes a third-party’s intellectual property rights;

● a court may prohibit us or our joint ventures from producing and selling our or their product(s) without a license from the holder of the intellectual property rights, which may not be available on commercially acceptable terms, if at all; and

● we or our joint ventures may have to reformulate product(s) so that it does not infringe the intellectual property rights of others, which may not be possible or could be very expensive and time consuming.

Any costs incurred in connection with such events or the inability to sell our or our joint ventures’ products may have a material adverse effect on our business and results of operations.

45

We, our joint ventures and our collaboration partners may not be able to effectively enforce our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our or our joint venture’s products or drug candidates in all countries throughout the world would be prohibitively expensive. The requirements for patentability may differ in certain countries, particularly in developing countries. Moreover, our, our joint ventures’ or our collaboration partners’ ability to protect and enforce our or their intellectual property rights may be adversely affected by unforeseen changes in foreign intellectual property laws. Additionally, the patent laws of some foreign countries do not afford intellectual property protection to the same extent as the laws of the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, may not favor the enforcement of patents and other intellectual property rights. This could make it difficult for us or our joint ventures to stop the infringement of our or their patents or the misappropriation of our or their other intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. Consequently, we may not be able to prevent third parties from practicing our or our joint ventures’ inventions throughout the world. Competitors may use our or our joint ventures’ technologies in jurisdictions where we or they have not obtained patent protection to develop their own drugs and, further, may export otherwise infringing drugs to territories where we or our joint ventures have patent protection, if our, our joint ventures’ or our collaboration partners’ ability to enforce our or their patents to stop infringing activities is inadequate. These drugs may compete with our drug candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Proceedings to enforce our or our joint ventures’ patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our or their efforts and resources from other aspects of our and their businesses. While we intend to protect our intellectual property rights in the major markets for our drug candidates, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our drug candidates. Furthermore, as AstraZeneca is responsible for enforcing our intellectual property rights with respect to savolitinib on our behalf, we may be unable to ensure that such rights are enforced or maintained in all jurisdictions. Accordingly, our efforts to protect the intellectual property rights of our drug candidates in such countries may be inadequate.

We and our joint ventures may be subject to damages resulting from claims that we or they, or our or their employees, have wrongfully used or disclosed alleged trade secrets of competitors or are in breach of non-competition or non-solicitation agreements with competitors.

We and our joint ventures could in the future be subject to claims that we or they, or our or their employees, have inadvertently or otherwise used or disclosed alleged trade secrets or other proprietary information of former employers or competitors. Although we try to ensure that our and our joint ventures’ employees and consultants do not improperly use the intellectual property, proprietary information, know-how or trade secrets of others in their work for us or our joint ventures, we or our joint ventures may in the future be subject to claims that we or they caused an employee to breach the terms of his or her non-competition or non-solicitation agreement, or that we, our joint ventures, or these individuals have, inadvertently or otherwise, used or disclosed the alleged trade secrets or other proprietary information of a former employer or competitor. Litigation may be necessary to defend against these claims. Even if we and our joint ventures are successful in defending against these claims, litigation could result in substantial costs and could be a distraction to management. If our or our joint ventures’ defenses to these claims fail, in addition to requiring us and them to pay monetary damages, a court could prohibit us or our joint ventures from using technologies or features that are essential to our or their products or our drug candidates, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former employers. An inability to incorporate such technologies or features would have a material adverse effect on our business, and may prevent us from successfully commercializing our drug candidates. In addition, we or our joint ventures may lose valuable intellectual property rights or personnel as a result of such claims. Moreover, any such litigation or the threat thereof may adversely affect our or our joint ventures’ ability to hire employees or contract with independent sales representatives. A loss of key personnel or their work product could hamper or prevent our ability to commercialize our drug candidates, which would have an adverse effect on our business, results of operations and financial condition.

Risks Relating to Our ADSs

Our largest shareholder owns a significant percentage of our ordinary shares, which may limit the ability of other shareholders to influence corporate matters.

As of March 1, 2020, Hutchison Healthcare Holdings Limited owned approximately 48.2% of our ordinary shares. Accordingly, Hutchison Healthcare Holdings Limited has a significant influence over the outcome of any corporate transaction or other matter submitted to shareholders for approval and the interests of Hutchison Healthcare Holdings Limited may differ from the interests of our other shareholders. Because we are incorporated in the Cayman Islands, certain matters, such as amendments to our Memorandum and Articles of Association, require approval of at least two-thirds of our shareholders by law subject to higher thresholds which we may set in our Articles of Association. Therefore, Hutchison Healthcare Holdings Limited’s approval will be required to achieve any such threshold. In addition, Hutchison Healthcare Holdings Limited has and will continue to have a significant influence over the management and the strategic direction of our company.

Substantial future sales or perceived potential sales of our ADSs, ordinary shares or other equity or equity-linked securities in the public market could cause the price of our ADSs to decline significantly.

Sales of our ADSs, ordinary shares or other equity or equity-linked securities in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline significantly. All of our ordinary shares represented by ADSs are freely transferable by persons other than our affiliates without restriction or additional registration under the Securities Act of 1933, or the Securities Act. The ordinary shares held by our affiliates are also available for sale, subject to volume and other restrictions as applicable under Rules 144 and 701 under the Securities Act, under sales plans adopted pursuant to Rule 10b5-1 or otherwise.

We have filed with the SEC a Registration Statement on Form F-3, commonly referred to as a “shelf registration,” that permits us to sell any number of ADSs in a registered offering at our discretion. Since effectiveness, we have completed registered offerings raising aggregate gross proceeds of approximately $419.6 million under the shelf registration statement. In addition, our largest shareholder has completed registered secondary offerings raising aggregate gross proceeds of approximately $310.4 million for it as selling shareholder under the shelf registration statement. We may decide to conduct future offerings from time to time, and such sales could cause the price of our ADSs to decline significantly.

We may be at a risk of securities litigation.

Historically, securities litigation, particularly class action lawsuits brought in the United States, have often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies have experienced significant share price volatility in recent years. If we were to be sued, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our business, the price of our ADSs could decline.

The trading market for our ADSs will rely in part on the research and reports that industry or financial analysts publish about us or our business. We may not be able to maintain continuous research coverage by industry or financial analysts. If one or more of the analysts covering our business downgrade their evaluations of our stock, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could lose visibility in the market for our stock, which in turn could cause our stock price to decline.

As a foreign private issuer, we are not subject to certain U.S. securities law disclosure requirements that apply to a domestic U.S. issuer, which may limit the information publicly available to our shareholders.

As a foreign private issuer we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act and therefore there may be less publicly available information about us than if we were a U.S. domestic issuer. For example, we are not subject to the proxy rules in the United States and disclosure with respect to our annual general meetings will be governed by the AIM Rules for Companies, or the AIM Rules, and Cayman Islands requirements. In addition, our officers, directors and principal shareholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules thereunder. Therefore, our shareholders may not know on a timely basis when our officers, directors and principal shareholders purchase or sell our ordinary shares or ADSs.

47

As a foreign private issuer, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from Nasdaq corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with corporate governance listing standards.

As a foreign private issuer, we are permitted to take advantage of certain provisions in the Nasdaq listing rules that allow us to follow Cayman Islands law for certain governance matters. Certain corporate governance practices in the Cayman Islands may differ significantly from corporate governance listing standards as, except for general fiduciary duties and duties of care, Cayman Islands law has no corporate governance regime which prescribes specific corporate governance standards. We intend to continue to follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the Nasdaq Global Select Market in respect of the following: (i) the majority independent director requirement under Section 5605(b)(1) of the Nasdaq listing rules, (ii) the requirement under Section 5605(d) of the Nasdaq listing rules that a remuneration committee comprised solely of independent directors governed by a remuneration committee charter oversee executive compensation and (iii) the requirement under Section 5605(e) of the Nasdaq listing rules that director nominees be selected or recommended for selection by either a majority of the independent directors or a nominations committee comprised solely of independent directors. Cayman Islands law does not impose a requirement that our board of directors consist of a majority of independent directors. Nor does Cayman Islands law impose specific requirements on the establishment of a remuneration committee or nominating committee or nominating process. Therefore, our shareholders may be afforded less protection than they otherwise would have under corporate governance listing standards applicable to U.S. domestic issuers. We have voluntarily complied with many of the principles of the U.K. published by the U.K. Financial Reporting Council which guides certain of our other corporate governance practices. See Item 6.C. “Board Practice—U.K. Corporate Governance Code” for more details.

Fluctuations in the value of the renminbi may have a material adverse effect on your investment.

The value of the renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the renminbi to the U.S. dollar, and the renminbi appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted, and the exchange rate between the renminbi and U.S. dollar remained within a narrow band. In June 2010, China’s People’s Bank of China, or PBOC, announced that the PRC government would increase the flexibility of the exchange rate, and thereafter allowed the renminbi to appreciate slowly against the U.S. dollar within the narrow band fixed by the PBOC. However, on August 11, 12 and 13, 2015, the PBOC significantly devalued the renminbi by fixing its price against the U.S. dollar 1.9%, 1.6%, and 1.1% lower than the previous day’s value, respectively. In 2016, the renminbi further depreciated against the U.S. dollar by approximately 7.1%, but in 2017, the renminbi appreciated against the U.S. dollar by 5.9%. In 2018 and 2019, the renminbi again depreciated against the U.S. dollar and ended down by 4.4% and 2.8%, respectively.

Significant revaluation of the renminbi may have a material adverse effect on your investment. For example, to the extent that we need to convert U.S. dollars into renminbi for our operations, appreciation of the renminbi against the U.S. dollar would have an adverse effect on the renminbi amount we would receive from the conversion. Conversely, if we decide to convert our renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the renminbi would have a negative effect on the U.S. dollar amount available to us. Appreciation or depreciation in the value of the renminbi relative to U.S. dollars would affect our financial results reported in U.S. dollar terms regardless of any underlying change in our business or results of operations. In addition, our operating transactions and assets and liabilities in the PRC are mainly denominated in renminbi. Such amounts are translated into U.S. dollars for purpose of preparing our consolidated financial statements, with translation adjustments reflected in accumulated other comprehensive (loss)/income in shareholders’ equity. We recorded a foreign currency translation loss of $6.6 million and $4.3 million for the years ended December 31, 2018 and 2019, respectively, and a foreign currency translation gain of $11.0 million for the year ended December 31, 2017.

Very limited hedging options are available in China to reduce our exposure to exchange rate fluctuations. To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedge our exposure or at all. In addition, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert renminbi into foreign currency.

48

We may in the future lose our foreign private issuer status under U.S. securities laws, which could result in significant additional costs and expenses.

We are a foreign private issuer as defined in the Securities Act, and therefore, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act. The determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter, and, accordingly, the next determination will be made with respect to us on June 30, 2019. We would lose our foreign private issuer status if, for example, more than 50% of our ordinary shares are directly or indirectly held by residents of the United States on June 30, 2020 and we fail to meet additional requirements necessary to maintain our foreign private issuer status. If we lose our foreign private issuer status on this date, we will be required to file with the SEC periodic reports and registration statements on U.S. domestic issuer forms beginning on January 1, 2020, which are more detailed and extensive than the forms available to a foreign private issuer. We will also have to mandatorily comply with U.S. federal proxy requirements, and our officers, directors and principal shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. In addition, we will lose our ability to rely upon exemptions from certain corporate governance requirements under the Nasdaq listing rules. As a U.S.-listed public company, should we lose our foreign private issuer status, we will incur significant additional legal, accounting and other expenses that we would not incur as a foreign private issuer.

We could be adversely affected if satisfactory progress is not made in discussions between the SEC and the U.S. Public Company Accounting Oversight Board, or PCAOB, on the one hand, and Chinese regulators, on the other, regarding improved access to information and audit inspections of accounting firms by the SEC and PCAOB, and certain audit reports incorporated by reference in this prospectus supplement were prepared by auditors who are not so inspected.

In late 2012, the SEC commenced administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, against the Chinese affiliates of the ‘‘big four’’ accounting firms (including our auditors). The Rule 102(e) proceedings initiated by the SEC relate to these firms’ inability to produce documents, including audit work papers, in response to the request of the SEC pursuant to Section 106 of the Sarbanes-Oxley Act, as the auditors located in China are not in a position to lawfully produce documents directly to the SEC because of restrictions under PRC law and specific directives issued by the China Securities Regulatory Commission, or CSRC. The issues raised by the proceedings are not specific to our auditors or to us, but affect all audit firms based in China and all companies listed in the United States with significant operations in China.

In January 2014, the administrative judge reached an initial decision that the Chinese affiliates of the “big four” accounting firms should be barred from practicing before the SEC for six months. Thereafter, the accounting firms filed a petition for review of the initial decision, prompting the SEC Commissioners to review the initial decision, determine whether there had been any violation and, if so, determine the appropriate remedy to be placed on these audit firms. In February 2015, these Chinese affiliates each agreed to a censure and to pay a fine to the SEC to settle the dispute and avoid suspension of their ability to practice before the SEC and audit U.S.-listed companies. The settlement requires the firms to follow detailed procedures and to seek to provide the SEC with access to the Chinese firms’ audit documents via the CSRC. Under the settlement, the underlying proceeding against these Chinese affiliates was deemed dismissed without prejudice for four years after entry of the settlement. The four-year mark occurred on February 6, 2019. We cannot predict if the SEC will further challenge these Chinese affiliates’ compliance with U.S. law in connection with U.S. regulatory requests for audit work papers or if the results of such a challenge would result in the SEC imposing penalties such as suspensions.

In the event that these Chinese affiliates become subject to additional legal challenges by the SEC or PCAOB, depending upon the final outcome, companies listed in the United States with significant operations in China may find it difficult or impossible to retain auditors in respect of their operations in China, which could result in financial statements being determined to not be in compliance with the requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and could result in delisting. Moreover, any negative news about the proceedings against these audit firms may cause investor uncertainty regarding companies listed in the United States with significant operations in China and the market price of our ADSs may be adversely affected. Furthermore, because we have substantial operations within the PRC, our auditor and the auditors of certain of our joint ventures are not currently inspected by the PCAOB. This lack of PCAOB inspections in China prevents the PCAOB from regularly evaluating audits and quality control procedures of any auditors operating in China, including our auditor and the auditors of certain of our joint ventures. As a result, investors may be deprived of the benefits of PCAOB inspections. The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our auditor’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to PCAOB inspections. Investors may lose confidence in our reported financial information and procedures and the quality of our financial statements.

49

In December 2018, the SEC and the PCAOB issued a joint statement on regulatory access to audit and other information internationally that cites the ongoing challenges faced by them in overseeing the financial reporting of companies listed in the United States with operations in China, the absence of satisfactory progress in discussions on these issues with Chinese authorities and the potential for remedial action if significant information barriers persist. If our independent registered public accounting firm was denied, whether temporarily or otherwise, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined to not be in compliance with the requirements of the Exchange Act.

As part of a continued regulatory focus in the United States on access to audit and other information currently protected by national law, in particular China's, in June 2019, a bipartisan group of lawmakers introduced bills in both houses of Congress that would require the SEC to maintain a list of issuers for which the PCAOB is not able to inspect or investigate an auditor report issued by a foreign public accounting firm. The Ensuring Quality Information and Transparency for Abroad-Based Listings on our Exchanges (EQUITABLE) Act prescribes increased disclosure requirements for such issuers and, beginning in 2025, the delisting from national securities exchanges such as Nasdaq of issuers included for three consecutive years on the SEC's list. Enactment of this legislation or other efforts to increase U.S. regulatory access to audit information could cause investor uncertainty for affected issuers, including us, and the market price of our ADSs could be adversely affected. It is unclear if this proposed legislation will be enacted.

We do not currently intend to pay dividends on our securities, and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of the ADSs.

We have never declared or paid any dividends on our ordinary shares. We currently intend to invest our future earnings, if any, to fund our growth. Therefore, you are not likely to receive any dividends on your ADSs at least in the near term, and the success of an investment in ADSs will depend upon any future appreciation in its value. Consequently, investors may need to sell all or part of their holdings of ADSs after price appreciation, which may never occur, to realize any future gains on their investment. There is no guarantee that the ADSs will appreciate in value or even maintain the price at which our shareholders have purchased the ADSs.

The trading  prices for our ADSs may be volatile which could result in substantial losses to you.

The market price of our ADSs has been volatile. From March 17, 2016 to March 1, 2020, the closing sale price of our ADSs ranged from a high of $41.14 to a low of $11.26 per ADS.

The market price for our ADSs is likely to be highly volatile and subject to wide fluctuations in response to factors, including the following:

● announcements of competitive developments;

● regulatory developments affecting us, our customers or our competitors;

● announcements regarding litigation or administrative proceedings involving us;

● actual or anticipated fluctuations in our period-to-period operating results;

● changes in financial estimates by securities research analysts;

● additions or departures of our executive officers;

● release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares or ADSs; and

● sales or perceived sales of additional ordinary shares or ADSs.

In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. For example, in 2019, the exchanges in China experienced a sharp decline as a result of a slowdown in the Chinese economy and trade tensions with the United States. Prolonged global capital markets volatility may affect overall investor sentiment towards our ADSs, which would also negatively affect the trading prices for our ADSs.

50

The dual listing of our ordinary shares and the ADSs may adversely affect the liquidity and value of the ADSs.

Our ordinary shares continue to be listed on the AIM market of the London Stock Exchange. The dual listing of our ordinary shares and the ADSs may dilute the liquidity of these securities in one or both markets and may adversely affect the development of an active trading market for the ADSs in the United States. The price of the ADSs could also be adversely affected by trading in our ordinary shares on the AIM market. Furthermore, our ordinary shares trade on the AIM market of the London Stock Exchange in the form of depository interests, each of which is an electronic book-entry interest representing one of our ordinary shares. However, the ADSs are backed by physical ordinary share certificates, and the depositary for our ADS program is unable to accept depository interests into its custody in order to issue ADSs. As a result, if an ADS holder wishes to cancel its ADSs and instead hold depository interests for trading on the AIM market or vice versa, the issuance and cancellation process may be longer than if the depositary could accept such depository interests.

Although our ordinary shares continue to be listed on the AIM market following our initial public offering in the United States completed in March 2016, we may decide at some point in the future to propose to our ordinary shareholders to delist our ordinary shares from the AIM market, and our ordinary shareholders may approve such delisting. We cannot predict the effect such delisting of our ordinary shares on the AIM market would have on the market price of the ADSs on the Nasdaq Global Select Market.

Fluctuations in the exchange rate between the U.S. dollar and the pound sterling may increase the risk of holding the ADSs.

Our share price is quoted on the AIM market of the London Stock Exchange in pence sterling, while the ADSs will trade on Nasdaq in U.S. dollars. Fluctuations in the exchange rate between the U.S. dollar and the pound sterling may result in temporary differences between the value of the ADSs and the value of our ordinary shares, which may result in heavy trading by investors seeking to exploit such differences. In addition, as a result of fluctuations in the exchange rate between the U.S. dollar and the pound sterling, the U.S. dollar equivalent of the proceeds that a holder of the ADSs would receive upon the sale in the United Kingdom of any shares withdrawn from the depositary and the U.S. dollar equivalent of any cash dividends paid in pound sterling on our shares represented by the ADSs could also decline.

Securities traded on the AIM market of the London Stock Exchange may carry a higher risk than shares traded on other exchanges and may impact the value of your investment.

Our ordinary shares are currently traded on the AIM market of the London Stock Exchange. Investment in equities traded on AIM is perceived by some to carry a higher risk than an investment in equities quoted on exchanges with more stringent listing requirements, such as the New York Stock Exchange or the Nasdaq. This is because the AIM market imposes less stringent ongoing reporting requirements than those other exchanges. You should be aware that the value of our ordinary shares may be influenced by many factors, some of which may be specific to us and some of which may affect AIM-listed companies generally, including the depth and liquidity of the market, our performance, a large or small volume of trading in our ordinary shares, legislative changes and general economic, political or regulatory conditions, and that the prices may be volatile and subject to extensive fluctuations. Therefore, the market price of our ordinary shares underlying the ADSs may not reflect the underlying value of our company.

The depositary for our ADSs gives us a discretionary proxy to vote our ordinary shares underlying your ADSs if you do not vote at shareholders’ meetings, except in limited circumstances, which could adversely affect your interests.

Under the deposit agreement for the ADSs, the depositary gives us a discretionary proxy to vote our ordinary shares underlying your ADSs at shareholders’ meetings if you do not vote, unless:

● we do not wish a discretionary proxy to be given;

● we are aware or should reasonably be aware that there is substantial opposition as to a matter to be voted on at the meeting; or

● a matter to be voted on at the meeting would materially and adversely affect the rights of shareholders.

The effect of this discretionary proxy is that you cannot prevent our ordinary shares underlying your ADSs from being voted, absent the situations described above, and it may make it more difficult for shareholders to influence the management of our company. Holders of our ordinary shares are not subject to this discretionary proxy.

51

Holders of ADSs have fewer rights than shareholders and must act through the depositary to exercise their rights.

Holders of our ADSs do not have the same rights as our shareholders and may only exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Under our memorandum and articles of association, an annual general meeting and any extraordinary general meeting at which the passing of a special resolution is to be considered may be called with not less than 21 clear days’ notice, and all other extraordinary general meetings may be called with not less than 14 clear days’ notice. When a general meeting is convened, you may not receive sufficient notice of a shareholders’ meeting to permit you to withdraw the ordinary shares underlying your ADSs to allow you to vote with respect to any specific matter. If we ask for your instructions, we will give the depositary notice of any such meeting and details concerning the matters to be voted upon at least 30 days in advance of the meeting date and the depositary will send a notice to you about the upcoming vote and will arrange to deliver our voting materials to you. The depositary and its agents, however, may not be able to send voting instructions to you or carry out your voting instructions in a timely manner. We will make all reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but we cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote the ordinary shares underlying your ADSs. Furthermore, the depositary will not be liable for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you request. In addition, in your capacity as an ADS holder, you will not be able to call a shareholders’ meeting.

You may not receive distributions on our ADSs or any value for them if such distribution is illegal or if any required government approval cannot be obtained in order to make such distribution available to you.

Although we do not have any present plan to pay any dividends, the depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on ordinary shares or other deposited securities underlying our ADSs, after deducting its fees and expenses and any applicable taxes and governmental charges. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists of securities whose offering would require registration under the Securities Act but is not so properly registered or distributed under an applicable exemption from registration. The depositary may also determine that it is not reasonably practicable to distribute certain property. In these cases, the depositary may determine not to distribute such property. We have no obligation to register under the U.S. securities laws any offering of ADSs, ordinary shares, rights or other securities received through such distributions. We also have no obligation to take any other action to permit the distribution of ADSs, ordinary shares, rights or anything else to holders of ADSs. This means that you may not receive distributions we make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you. These restrictions may cause a material decline in the value of our ADSs.

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary bank will not make rights available to you unless either both the rights and any related securities are registered under the Securities Act, or the distribution of them to ADS holders is exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. If the depositary does not distribute the rights, it may, under the deposit agreement, either sell them, if possible, or allow them to lapse. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

52

If we are classified as a passive foreign investment company, U.S. investors could be subject to adverse U.S. federal income tax consequences.

The rules governing passive foreign investment companies, or PFICs, can have adverse effects for U.S. investors for U.S. federal income tax purposes. The tests for determining PFIC status for a taxable year depend upon the relative values of certain categories of assets and the relative amounts of certain kinds of income. As discussed in “Taxation—Material U.S. Federal Income Tax Considerations,” we do not believe that we are currently a PFIC. Notwithstanding the foregoing, the determination of whether we are a PFIC depends on particular facts and circumstances (such as the valuation of our assets, including goodwill and other intangible assets) and may also be affected by the application of the PFIC rules, which are subject to differing interpretations. The fair market value of our assets is expected to depend, in part, upon (1) the market price of our ordinary shares and ADSs and (2) the composition of our income and assets, which will be affected by how, and how quickly, we spend any cash that is raised in any financing transaction. In light of the foregoing, no assurance can be provided that we are not currently a PFIC or that we will not become a PFIC in any future taxable year. Furthermore, if we are treated as a PFIC, then one or more of our subsidiaries may also be treated as PFICs.

If we are or become a PFIC, and, if so, if one or more of our subsidiaries are treated as PFICs, U.S. holders of our ordinary shares and ADSs would be subject to adverse U.S. federal income tax consequences, such as ineligibility for any preferential tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional reporting requirements under U.S. federal income tax laws and regulations. Whether U.S. holders of our ordinary shares or ADSs make (or are eligible to make) a timely qualified electing fund, or QEF, election or a mark-to-market election may affect the U.S. federal income tax consequences to U.S. holders with respect to the acquisition, ownership and disposition of our ordinary shares and ADSs and any distributions such U.S. holders may receive. We do not, however, expect to provide the information regarding our income that would be necessary in order for a U.S. holder to make a QEF election if we are classified as a PFIC. Investors should consult their own tax advisors regarding all aspects of the application of the PFIC rules to our ordinary shares and ADSs.

You may have difficulty enforcing judgments obtained against us.

We are a company incorporated under the laws of the Cayman Islands, and substantially all of our assets are located outside the United States. Substantially all of our current operations are conducted in the PRC. In addition, most of our directors and officers are nationals and residents of countries other than the United States. A substantial portion of the assets of these persons are located outside the United States. As a result, it may be difficult for you to effect service of process within the United States upon these persons. It may also be difficult for you to enforce in U.S. courts judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors, all of whom are not residents in the United States and whose assets are located outside the United States. In addition, there is uncertainty as to whether the courts of the Cayman Islands or the PRC would recognize or enforce judgments of U.S. courts against us or such persons predicated upon the civil liability provisions of the securities laws of the United States or any state.

You may be subject to limitations on transfers of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We are a Cayman Islands company. As judicial precedent regarding the rights of shareholders is more limited under Cayman Islands law than under U.S. law or English law, shareholders may have different shareholder rights than they would have under U.S. law or English law and may face difficulties in protecting your interests.

We are an exempted company with limited liability incorporated in the Cayman Islands. Our corporate affairs are governed by our Articles of Association (as may be further amended from time to time), the Companies Law (as amended) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors are to a large extent governed by the common law of the Cayman Islands. This common law is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in England and some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities law than the United States or the United Kingdom. In addition, some states in the United States, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands.

In addition, as a Cayman Islands exempted company, our shareholders have no general rights under Cayman Islands law to inspect corporate records and accounts or to obtain copies of lists of shareholders of these companies with the exception that the shareholders may request a copy of the Articles of Association. Our directors have discretion under our Articles of Association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest. As a Cayman Islands company, we may not have standing to initiate a derivative action in U.S. federal courts or English courts. As a result, you may be limited in your ability to protect your interests if you are harmed in a manner that would otherwise enable you to sue in U.S. federal courts or English courts. In addition, shareholders of Cayman Islands companies may not have standing to initiate a shareholder derivative action in U.S. federal courts or English courts.

Some of our directors and executive officers reside outside of the United States and a substantial portion of their assets are located outside of the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the securities laws of the United States or otherwise. In addition, some of our operating subsidiaries are incorporated in China. To the extent our directors and executive officers reside in China or their assets are located in China, it may not be possible for investors to effect service of process upon us or our management inside China. Even if you are successful in bringing an action, the laws of the Cayman Islands and China may render you unable to enforce a judgment against our assets or the assets of our directors and officers. There is no statutory recognition in the Cayman Islands of judgments obtained in the United States or China, although the courts of the Cayman Islands may generally recognize and enforce by action at common law a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of an English company or a U.S. company.

B.    Business Overview.

Overview

We are an innovative, commercial-stage biopharmaceutical company based in China aiming to become a fully integrated global leader in the discovery, development and commercialization of targeted therapies and immunotherapies for the treatment of cancer and immunological diseases. Our strategy is to leverage the highly specialized expertise of our drug discovery division, known as our Innovation Platform, to develop and expand our drug candidate portfolio for the global market while also building on our first-mover advantage in the development and launch of novel cancer drugs in China. Over the last several years, we believe we have established the key building blocks for achieving this mission:

Global-facing Drug Discovery Platform Generating Multiple Waves of Innovation.

Our Innovation Platform has a comprehensive drug discovery and development operation covering chemistry, biology, pharmacology, toxicology, chemistry and manufacturing controls for clinical and commercial supply, clinical and regulatory and other functions. Focusing on both the global innovation and China oncology markets, our Innovation Platform is led by a team of approximately 500 scientists and staff. Currently, we have eight self-discovered drug candidates in clinical trials, five of which are in global clinical development.

Our drug candidates were developed based on our core research and development philosophy in treating cancer and immunological diseases through multiple modalities and mechanisms. Our first wave of drug candidates, including fruquintinib, surufatinib and savolitinib, are either at or approaching potential submission, approval and launch in major markets. In particular, savolitinib is being developed globally in partnership with AstraZeneca. Encouraging preliminary data from the TATTON study of savolitinib in combination with AstraZeneca's Tagrisso for non-small cell lung cancer patients led to the initiation of a global registration intent trial, known as the SAVANNAH study, in late 2018. Savolitinib is also being studied for the treatment of kidney and gastric cancer.

56

Our second wave of drug candidates, including HMPL-523 and HMPL-689 which focus on B-cell malignancies as well as combination therapies using our first wave drug candidates with programmed cell death protein 1, or PD-1, and programmed death-ligand 1, or PD-L1 inhibitors, are now mostly in proof-of-concept studies and will soon inform registration study decisions. In addition, our Innovation Platform is focusing on the third wave of innovation with a particular emphasis on studying additional combination therapies, developing HMPL-453 and HMPL-306 and furthering our pre-clinical programs for therapies addressing aberrant genetic drivers, inactivated T-cell response and insufficient T-cell response. We further plan to enrich our global pipeline of self-discovered drug candidates by advancing a broad range of early-stage drug candidates, which include biologics addressing novel targets designed for use in combination with our small molecules as well as potentially a broad range of third-party therapies. We expect to further expand our portfolio of drug candidates in oncological and immunological therapeutic areas by pursuing business development opportunities with other biopharmaceutical companies both in China and globally. In addition, we may explore opportunities to acquire rights to complementary drug candidates and/or interests in other biopharmaceutical companies to supplement our in-house research and development capabilities and to enhance our current drug candidate pipeline.

Achieving Clinical Success in China.

In late 2018, our Innovation Platform achieved an important milestone with the commercial launch of our self-discovered and developed drug fruquintinib, sold under the brand name Elunate, for the treatment of metastatic colorectal cancer in China. Fruquintinib is the first ever China-discovered and developed targeted oncology therapy to have received unconditional approval and be subsequently commercialized. This was followed in 2019 by the successful Phase III result and NDA, submission for our second self-discovered and developed oncology drug, surufatinib, for the treatment of non-pancreatic neuroendocrine tumors in China as well as the successful Phase III result for pancreatic neuroendocrine tumors in January 2020. We are now building an in-house oncology sales and marketing team so that we will be able to effectively commercialize surufatinib, which may be launched in China as early as this year. We currently have approximately 140 staff on our China oncology commercial team, and we plan to rapidly expand this team to approximately 300 to 350 staff to support surufatinib's potential launch.

Well-positioned to Capture Market Opportunities in China.

We believe that our long track record of research and development will enable us to take advantage of the significant market opportunities in China, which have been buoyed by the PRC government's recent policy reforms aimed at accelerating domestic innovative drug development and the expansion of access to world-class medicines for the people of China. The PRC government has enacted a series of policies to shorten the review and approval time for innovative drugs that address significant medical needs such as our drug candidate surufatinib, which was granted priority review by the NMPA in December 2019. In addition, national-, city- and provincial-level medical insurance reimbursement has been expanding rapidly, thereby reducing out-of-pocket treatment cost for patients. Beginning this year, Elunate is now included on China's National Reimbursement Drug List, which we believe is likely to give significantly more advanced colorectal cancer patients access to this treatment.

Productive U.S. Clinical Team Driving International Development.

In line with our strategy to expand clinical activities globally, we commenced operation of our U.S. subsidiary, Hutchison MediPharma International Inc. at our new office in New Jersey in early 2018. Our U.S.-based clinical team aims to support our growth strategy outside of China, significantly broadening our international clinical development operations, particularly in the United States, Europe and Japan. This team has demonstrated a productive track record by gaining orphan drug designation for surufatinib from the FDA and initiating global Phase I trials for HMPL-523 and HMPL-689 in 2019, and is planning global Phase III registration studies of fruquintinib and surufatinib, which are expected to be initiated this year.

Innovation Platform—Global Clinical Drug Development

We believe our drug candidates in global development—savolitinib, fruquintinib, surufatinib (previously named sulfatinib), HMPL-523 and HMPL-689—are uniquely selective and/or differentiated and have the potential to be global first-in-class and/or best-in-class therapies.

57

The following table summarizes the status of our global clinical drug portfolio's development as of the date of the filing of this annual report.

Our Global Clinical Development Pipeline

Notes:    Dose finding/safety run-in = Phase I/Ia studies; Proof-of-concept = Phase Ib, Ib/II or II studies; Registration = Phase II, II/III or III registration intent studies; NSCLC = non-small cell lung cancer; RCC = renal cell carcinoma; NHL = Non-Hodgkin's Lymphoma; 1L = first line; 2L = second line; 3L = third line; 4L = fourth line; ref. or refractory = resistant to prior treatment; intol. = intolerant to prior treatment; TKI = tyrosine kinase inhibitor; * Phase II registration intent study subject to regulatory discussions; ** investigator-initiated study; and *** In planning.

Over the next several years, we intend to accelerate development of our global clinical drug portfolio through existing partnerships such as that with AstraZeneca, as well as increasingly through our own expanding clinical and regulatory operations in the United States, Europe and Japan.

● Savolitinib-potential first-in-class selective MET inhibitor in late-stage clinical development as a monotherapy and in combination therapies in global partnership with AstraZeneca

Savolitinib is a potent and selective inhibitor of the mesenchymal epithelial transition factor, or MET, receptor tyrosine kinase, an enzyme which has been shown to function abnormally in many types of solid tumors. We designed savolitinib through chemical structure modification to specifically address kidney toxicity, the primary issue that halted development of several other selective MET inhibitors. In clinical trials to date in over 1,000 patients globally, savolitinib has shown promising signs of clinical efficacy in patients with MET gene alterations in lung cancer, kidney cancer, gastric cancer and prostate cancer with an acceptable safety profile.

58

We are currently testing savolitinib in global partnership with AstraZeneca, both as a monotherapy and in combination with immunotherapy, targeted therapy and chemotherapy drugs. Most notably, we are currently progressing the SAVANNAH study on savolitinib in combination with Tagrisso for treating epidermal growth factor receptor mutation, or EGFRm, non-small cell lung cancer patients who have progressed following first or second-line Tagrisso therapy due to MET amplification. We target to conduct an interim analysis of the SAVANNAH study and begin regulatory discussions in mid-2020, which will guide our registration strategy for this combination therapy.

We also anticipate announcing plans for multiple further clinical studies on savolitinib in the coming months. In addition, we plan to submit the results of our Phase II registration study of savolitinib in patients with MET Exon 14 deletion NSCLC in China, as well as a Phase III study of savolitinib in patients with MET-driven papillary renal cell carcinoma, known as the SAVOIR study, for presentation at an upcoming scientific conference in mid-2020, and we intend to initiate further development of savolitinib for these indications.

Proof-of-concept studies of savolitinib in kidney cancer (as a monotherapy as well as in combination with a PD-L1 inhibitor) and gastric cancer (as a monotherapy as well as in combinations with chemotherapy) have either been presented or are expected to be submitted for publication in peer-reviewed journals or presentation at international scientific conferences in 2020 and, if the results of such studies are positive, they are likely to lead to subsequent clinical development.

● Fruquintinib—potential best-in-class selective VEGFR 1, 2 and 3 inhibitor

Fruquintinib is a highly selective and potent oral inhibitor of vascular endothelial growth factor receptors, known as VEGFR 1, 2 and 3. We believe that fruquintinib has the potential to become the global best-in-class selective small molecule VEGFR 1, 2 and 3 inhibitor for many types of solid tumors, and we are currently studying fruquintinib in colorectal cancer, gastric cancer and lung cancer. Fruquintinib was designed to improve kinase selectivity to minimize off-target toxicities, improve tolerability and provide more consistent target coverage. The tolerability in patients to date, along with fruquintinib's low potential for drug-drug interaction based on preclinical assessment, suggests that it may be highly suitable for combinations with other anti-cancer therapies. Fruquintinib has been approved for the treatment of third-line metastatic colorectal cancer in China.

Building on the data collected from our successful Phase III trial in China, known as the FRESCO study, which supported fruquintinib's approval in China, and the ongoing Phase Ib dose finding study of fruquintinib in the United States, we are planning to initiate a Phase III registration study of fruquintinib in the United States and Europe as a treatment for metastatic colorectal cancer patients during 2020. We also intend to conduct global combination studies of fruquintinib with Tyvyt, a PD-1 monoclonal antibody developed by Innovent Biologics (Suzhou) Co. Ltd., or Innovent, and recently approved for clinical development in both China, where we are currently enrolling a Phase I/II study, and the United States, where a global dose confirmation study is in planning and expected to be initiated in 2020.

Fruquintinib is being commercialized and developed in partnership with Eli Lilly in China. We own all rights to fruquintinib outside of China.

● Surufatinib—unique angio-immuno kinase inhibitor

Surufatinib is an novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with VEGFR and fibroblast growth factor receptor, or FGFR, which both inhibit angiogenesis, and colony stimulating factor-1 receptor, or CSF-1R, which regulates tumor-associated macrophages, promoting the body's immune response against tumor cells. Its unique dual mechanism of action may be very suitable for possible combinations with other immunotherapies. Surufatinib is the first oncology candidate that we have taken unpartnered through NDA submission in China and have expanded development globally ourselves.

59

We have various additional clinical trials of surufatinib ongoing as a single agent in patients with neuroendocrine tumors, biliary tract cancer and soft-tissue sarcoma, as well as in combination with checkpoint inhibitors. The encouraging data from our Phase II and Phase III studies of surufatinib in neuroendocrine tumor patients in China and the ongoing Phase Ib study in the United States of surufatinib in neuroendocrine tumor patients is guiding our planning for a registration study in the United States and Europe. The FDA granted orphan drug designation to surufatinib for the treatment of pancreatic neuroendocrine tumors in November 2019, and we are planning to initiate a Phase III registration study of surufatinib in the United States and Europe as a treatment for neuroendocrine tumor patients in 2020. Similar to fruquintinib, we intend to conduct a combination study of surufatinib with Tuoyi, a PD-1 monoclonal antibody being developed by Shanghai Junshi Biosciences Co. Ltd., or Junshi, in both China, where we are currently enrolling a Phase II study, and the United States, where a Phase Ib/II study is in planning and expected to be initiated in 2020. A combination study with Innovent's Tyvyt is also being planned. We believe surufatinib has potential in a number of other tumor types such as breast cancer with FGFR 1 activation.

We own all rights to surufatinib globally.

● HMPL-523—potential first-in-class selective Syk inhibitor for oncology

HMPL-523 is a novel, highly selective, oral inhibitor targeting the spleen tyrosine kinase, or Syk, for the treatment of hematological cancers and certain chronic immune diseases. Syk is a major component in B-cell receptor signaling and is an established therapeutic target in multiple subtypes of B-cell lymphomas. Because B-cell malignancies are heterogeneous and patients commonly experience relapse despite current therapies, there is a need for new therapies.

We have various clinical trials of HMPL-523 ongoing. Based on extensive Phase I/Ib proof-of-concept clinical data in China and Australia on HMPL-523, we have now opened multiple U.S. and European sites for a Phase I/Ib study with patient enrollment underway, focusing on advanced relapsed or refractory lymphoma.

We own all rights to HMPL-523 globally.

● HMPL-689—potential best-in-class selective PI3Kδ inhibitor

HMPL-689 is a novel, highly selective and potent small molecule inhibitor targeting the isoform PI3Kδ. In preclinical pharmacokinetic studies, HMPL-689's pharmacokinetic properties have been found to be favorable with good oral absorption, moderate tissue distribution and low clearance. HMPL-689 is also expected to have low risk of drug accumulation and drug-drug interaction and is highly potent, particularly at the whole blood level.

We have early-stage clinical trials of HMPL-689 ongoing. Based on extensive Phase I/Ib proof-of-concept clinical data in China and Australia on HMPL-689, we have now opened multiple U.S. and European sites for a Phase I/Ib study with patient enrollment underway, focusing on advanced relapsed or refractory lymphoma.

We own all rights to HMPL-689 globally.

Innovation Platform—China Oncology Drug Development

The Chinese oncology market, which comprises approximately a quarter of the global oncology patient population, represents a substantial and fast-growing market opportunity. Strong market growth is expected to be driven by gradually improving affordability for world-class novel oncology drugs and the PRC government's increasing emphasis on innovation combined with rapidly reforming regulatory infrastructure. We believe our established presence in China, combined with our ability to deliver global-quality innovation, positions us well to address the major unmet medical needs in the China oncology market.

With a deep and risk-balanced drug development pipeline focusing on both novel targets and validated targets, we currently have eight drug candidates in clinical development covering a dozen cancer targets, including fruquintinib which has already launched for its initial indication, as well as savolitinib and surufatinib which are in late-stage development in China. Our other drug candidates are also uniquely selective and/or differentiated and have the potential to be first-in-class or best-in-class oncology therapies in China.

As the first mover to bring a self-discovered and developed innovative targeted cancer treatment to market in China with the launch of Elunate, we believe we are well positioned to take advantage of this significant market opportunity.

60

Driven by our strong expertise in molecular-targeted drugs and commitment to combination therapies of our tyrosine kinase inhibitors with various immunotherapies, we entered into multiple global and China-only collaboration agreements with Innovent, Junshi, and Genor Biopharma Co. Ltd., or Genor, to evaluate the safety, tolerability and efficacy of fruquintinib and surufatinib in combination with various PD-1 inhibitors, which are important additions to our ongoing studies combining savolitinib with AstraZeneca’s PD-L1 inhibitor, Imfinzi.

The following table summarizes the status of our China clinical programs as of the date of the filing of this annual report.

Our China Clinical Development Pipeline

Notes:    Dose finding/safety run-in = Phase I/Ia studies; Proof-of-concept = Phase Ib, Ib/II or II studies; Registration = Phase II, II/III or III registration intent studies; NSCLC = non-small cell lung cancer; NET = neuroendocrine tumors; NHL = non-Hodgkin’s lymphoma; ref. or refractory = resistant to prior treatment; MET+ = MET-amplification; ITP = immune thrombocytopenia; 1L = first line; 2L = second line; 3L = third line; * In planning; and ** Discontinued.

61

● Savolitinib—potential first-in-class selective MET inhibitor in China

We are currently conducting a Phase II registration study in China of savolitinib in non-small cell lung cancer patients with MET Exon 14 mutation/deletion who have failed prior systemic therapy, or are unwilling or unable to receive chemotherapy, which completed enrollment in mid-2019. If the results from this study are positive, we hope this would be sufficient to support an NDA submission in China in early 2020. We believe MET Exon 14 mutation/deletion non-small cell lung cancer in China has the potential to be the first savolitinib indication approved.

● Fruquintinib—commercially launched in colorectal cancer in November 2018

At the end of 2018, our collaboration partner Eli Lilly commenced commercial sales of Elunate, the brand name of fruquintinib, targeting the more than 55,000 metastatic colorectal cancer third-line patients in China each year as of 2018. Starting on January 1, 2020, Elunate was included on China’s National Reimbursement Drug List. Therefore, Elunate is now available in public hospitals throughout China at a reduced price, paving the way to significantly broaden access for advanced colorectal cancer patients and rapidly build penetration in China over the coming years.

In addition to this commercial launch, we have made progress with fruquintinib in partnership with Eli Lilly in various other cancer indications, including the FRUTIGA study in China, a pivotal Phase III study to evaluate the efficacy and safety of fruquintinib in combination with Taxol compared with Taxol monotherapy for second-line treatment of advanced gastric cancer in patients who had failed first-line chemotherapy. We expect to conduct a second interim analysis in mid-2020 and complete enrollment of the study in 2020. We have also completed enrollment of a Phase II study in China of fruquintinib in combination with Iressa in first-line EGFR activating mutation non-small cell lung cancer, from which preliminary data has shown an encouraging efficacy and safety profile. Moreover, in addition to our global collaboration to evaluate the combination of fruquintinib with Innovent’s PD-1 monoclonal antibody Tyvyt, we have entered into a collaboration in China to evaluate the combination of fruquintinib with genolimzumab, a PD-1 monoclonal antibody being developed by Genor.

We believe that fruquintinib is a best-in-class VEGFR 1, 2 and 3 inhibitor and could be considered for development in China in many solid tumor indications in which VEGFR inhibitors have been approved globally. To this end, in 2018, we amended our collaboration agreement with Eli Lilly with respect to fruquintinib, which gives us, among others, all planning, execution and decision-making responsibilities for life cycle indication development of fruquintinib in China.

● Surufatinib—potential first-in-class inhibitor for all neuroendocrine tumors

In June 2019, an interim analysis of our SANET-ep study, a Phase III trial in non-pancreatic neuroendocrine tumor patients in China, confirmed that the trial met its primary endpoint of progression-free survival. As a result, the study was stopped early, and surufatinib’s NDA was granted priority review by the NMPA in December 2019. We are building a new China oncology commercial sales and marketing team in preparation for a potential launch of surufatinib as early as this year. As of the date of the filing of this annual report, we currently have approximately 140 staff on our China oncology commercial team, and we plan to rapidly expand this team to approximately 300 to 350 staff to support surufatinib’s potential launch.

A recent interim analysis of our Phase III study of surufatinib in pancreatic neuroendocrine tumor patients in China confirmed that the trial met its primary endpoint of progression-free survival, with the study’s independent data monitoring committee recommending that the study be stopped early. This positive result, along with that of SANET-ep, positions surufatinib to potentially be approved in the full spectrum of advanced neuroendocrine tumors, regardless of primary organ site, in China. We believe that no other approved targeted therapy can address and treat all subtypes of neuroendocrine tumors. We will now arrange for a pre-NDA meeting with the NMPA to discuss the preparation of the NDA for surufatinib for this indication.

In January 2020, we initiated a Phase II study in China of surufatinib in combination with Tuoyi in patients with advanced solid tumors. This follows the recent completion of the Phase I dose finding study and successful establishment of the Phase II combination dosing regimen for surufatinib and Tuoyi.

Based on encouraging Phase Ib data, a Phase IIb/III study in biliary tract cancer has also begun in China with the first patient dosed in March 2019.

62

● HMPL-523—highly selective Syk inhibitor with potential in hematological cancer and immunological diseases

Data from an extensive Phase I/Ib dose escalation and expansion study (covering more than 150 patients) on HMPL-523 has encouraged us to initiate exploratory studies in China on multiple indolent non-Hodgkin’s lymphoma sub-categories, including chronic lymphocytic leukemia/small lymphocytic lymphoma, follicular lymphoma, marginal zone lymphoma, Waldenstrom’s macroglobulinemia and mantle cell lymphoma. We expect these data to inform registration study decisions in China in 2020.

Furthermore, we have also commenced a Phase I study of HMPL-523 for the treatment of immune thrombocytopenia in China.

● HMPL-689—highly selective PI3Kδ inhibitor with potential in hematological cancer

Our Phase I dose escalation study on HMPL-689 in China had been completed and a recommended Phase II dose was selected. We are now conducting a Phase Ib expansion study in China in multiple sub-categories of indolent non-Hodgkin’s lymphoma. We expect these data to inform registration study decisions in China in 2020.

● HMPL-453—highly selective FGFR 1/2/3 inhibitor with potential in solid tumors

HMPL-453 is a highly selective and potent FGFR 1/2/3 inhibitor. In June 2017, we initiated a Phase I clinical trial of HMPL-453 in China. Enrollment is ongoing, and Phase II studies are expected to be initiated in 2020.

● HMPL-306—highly selective IDH 1 and 2 inhibitor with potential in hematological malignancies, gliomas and solid tumors

In August 2019, the NMPA approved our investigational new drug, or IND, application for HMPL-306, a novel small molecule dual-inhibitor of isocitrate dehydrogenase 1 and 2, or IDH 1 and 2, enzymes. IDH1 and IDH2 mutations have been implicated as drivers of certain hematological malignancies, gliomas and solid tumors, particularly among acute myeloid leukemia patients. We expect to begin Phase I development in mid-2020.

● Epitinib and theliatinib—clinical-stage EGFR inhibitors

We have completed Phase I/Ib studies of both epitinib, an EGFR inhibitor with demonstrated ability to penetrate the blood-brain barrier, and theliatinib, a novel small molecule EGFR inhibitor. We are evaluating further development strategies for epitinib and theliatinib.

Global-facing Discovery Engine

We strive to create differentiated novel oncology and immunology treatments with global potential. These include furthering both small molecule and monoclonal antibody therapies which address aberrant genetic drivers, inactivated T-cell response and insufficient T-cell response. We design drug candidates with profiles that enable them to be used in innovative combinations with other therapies, such as chemotherapy, immunotherapy and other targeted therapy in order to attack disease through multiple modalities and pathways simultaneously. We believe that this approach can significantly improve treatment outcomes for patients.

Commercial Platform

In addition to our Innovation Platform, we have established a profitable Commercial Platform in China. Our Commercial Platform is a large-scale drug marketing and distribution platform covering over 330 cities and towns in China with approximately 3,500 sales personnel as of December 31, 2019.

Built over the past 19 years, it has been focused on two main business areas. First is our Prescription Drugs business, which includes our current and future internally developed drug candidates and our joint ventures Shanghai Hutchison Pharmaceuticals and Hutchison Sinopharm and for which we manage directly and run all day-to-day operations. Second is our Consumer Health business, which mainly sells market-leading, household-name over-the-counter drug products through our non-consolidated joint venture Hutchison Baiyunshan.

63

Our Clinical Pipeline

The following is a summary of the clinical pipeline for our drug candidates, many of which are being investigated against multiple indications.

1.    Savolitinib MET Inhibitor

Savolitinib is a potent and selective inhibitor of MET, an enzyme which has been shown to function abnormally in many types of solid tumors. We designed savolitinib to address human metabolite-related renal toxicity, the primary issue that halted development of several other selective MET inhibitors. In clinical studies to date, savolitinib has shown promising signs of clinical efficacy in patients with MET gene alterations in non-small cell lung cancer, papillary renal cell carcinoma, colorectal cancer, gastric cancer and prostate cancer with an acceptable safety profile. In global partnership with AstraZeneca, savolitinib has been studied in over 1,000 patients to date, both as a monotherapy and in combinations. For more information regarding our partnership with AstraZeneca, see “– Overview of Our Collaborations – AstraZeneca Agreement.”

Mechanism of Action

MET is a signaling pathway that has specific roles in normal mammalian growth and development. However, the MET pathway has also been shown to function abnormally in a range of different cancers, primarily through MET gene amplification, overexpressed and gene mutations. The aberrant activation of MET has been demonstrated to be highly correlated in many cancer indications, including kidney, lung, gastric, colorectal, esophageal and brain cancer. It plays a major role in cancer pathogenesis (i.e., the development of the cancer), including tumor growth, survival, invasion, metastasis, the suppression of cell death as well as tumor angiogenesis.

MET also plays a role in drug resistance in many tumor types. For instance, MET gene amplification has been found in non-small cell lung cancer and colorectal cancer following anti-EGFR treatment, leading to drug resistance. Furthermore, MET dysregulation is considered to play a role in the immunosuppression and pathogenesis of kidney cancer.

Savolitinib Research Background

Selective MET compounds previously discovered by multinational pharmaceutical companies had positive pre-clinical data that supported their high MET selectivity and pharmacokinetic and toxicity profiles, but did not progress very far due to kidney toxicity. The issue appeared to be that certain metabolites of earlier compounds had dramatically reduced solubility and appeared to crystalize in the kidney, resulting in obstructive toxicity. With this understanding, we designed our compound, savolitinib (also known as AZD6094 and HMPL-504, formerly known as volitinib), differently while preserving high MET selective properties. Savolitinib has not shown any renal toxicity to date and does not appear to carry the same metabolite problems as the earlier selective MET compounds.

Savolitinib Pre-clinical Evidence

In pre-clinical trials, savolitinib demonstrated strong in vitro activity against MET, affecting its downstream signaling targets and thus blocking the related cellular functions effectively, including proliferation, migration, invasion, scattering and the secretion of vascular endothelial growth factor, or VEGF, that plays a pivotal role in tumor angiogenesis.

One of our key areas of focus in our pre-clinical trials is to achieve superior selectivity on a number of kinases. A commonly used quantitative measure of selectivity is through comparing enzyme IC₅₀, which represents the concentration of a drug that is required for 50% inhibition of the target kinase in vitro and the plasma concentration required for obtaining 50% of a maximum effect in vivo. High selectivity is achieved with a very low IC₅₀ for the target cells, and a very high IC₅₀ for the healthy cells (approximately 100 times higher than for the target cells). IC₅₀ is measured in nM (nano-mole, a microscopic unit of measurement for the number of small molecules required to deliver the desired inhibitory effect).

In the MET enzymatic assay, savolitinib showed potent activity with IC₅₀ of 5 nM. In a kinase selectivity screening with 274 kinases, savolitinib had potent activity against the MET Y1268T mutant (comparable to the wild-type), weaker activity against other MET mutants and almost no activity against all other kinases. Savolitinib was found to be approximately 1,000 times more potent to MET than the next non-MET kinase. Similarly, in cell-based assays measuring activity against MET phosphorylation, savolitinib demonstrated potent activity in both ligand-independent (gene amplified) and ligand-dependent (overexpressed) cells with IC_50s at low nanomolar levels. In target related tumor cell function assays, savolitinib showed high potency with IC₅₀ of less than 10 nM. This compares favorably to the potency of Xalkori from its independently conducted preclinical studies, which showed Xalkori to be 10 to 40 times less potent than savolitinib with respect to certain ligands. Furthermore, savolitinib demonstrated cytotoxicity only on tumor cells that were MET gene amplified or MET overexpressed. In other cells, inhibition measurements demonstrated that IC₅₀ amounts were over 30,000 nM, which is thousands of times higher than the IC₅₀ on MET tumor cells.

64

The data above suggest that (i) savolitinib has potent activity against tumor cell lines with MET gene amplification in the absence of HGF, indicating that there is HGF-independent MET activation in these cells; (ii) savolitinib has potent activity in tumor cell lines with MET overexpressed, but only in the presence of HGF, indicating HGF-dependent MET activation; and (iii) savolitinib has no activity in tumor cell lines with low MET overexpressed/gene amplification, suggesting that savolitinib has strong kinase selectivity.

Savolitinib Clinical Development

As discussed below, we have tested, and are currently testing, savolitinib in partnership with AstraZeneca in multiple indications, both as a monotherapy and in combination with other targeted therapies.

Non-small Cell Lung Cancer

We have two ongoing studies, which subject to positive clinical outcome, are designed to support NDA submission in non-small cell lung cancer. The table below shows a summary of the clinical trials that we have recently completed and underway for savolitinib in non-small cell lung cancer patients.

Savolitinib Monotherapy

It is estimated that 2-3% of newly diagnosed non-small cell lung cancer patients have a specific genetic mutation, known as MET Exon 14 deletion, where exon 14 of the MET gene is either deleted or not functional, resulting in MET overexpression, which predicts prognosis and is believed to play an important role in tumor growth. This equates to approximately 10,000 new patients per year in China. Current chemotherapies and immunotherapies provide limited efficacy in MET Exon 14 deletion non-small cell lung cancer patients.

Phase II study of savolitinib monotherapy in non-small cell lung cancer patients with MET Exon 14 deletion (Status: completed enrollment; NCT02897479)

We have completed enrollment of a 70-patient Phase II registration-intent study in China of savolitinib as a monotherapy for MET Exon 14 deletion non-small cell lung cancer patients who have progressed following prior systemic therapy, or unable to receive chemotherapy.

At the Chinese Society of Clinical Oncology Annual Meeting in September 2019, we presented interim data on 50 treated patients, of which 36 patients were efficacy evaluable at the time of data cut-off. The overall data were encouraging, with efficacy in line with other selective MET inhibitors and with tolerable safety. Treatment emergent CTC grade 3 or above adverse events with greater than 5% incidence related to savolitinib treatment were peripheral edema (8%), increased aspartate aminotransferase (8%) and increased alanine aminotransferase (6%).

Based on the feedback from our regulatory discussions with the NMPA, we now intend to submit an NDA for this indication in China in early 2020. We also plan to submit the data for an upcoming scientific conference presentation in 2020.

Savolitinib and Tagrisso Combination

In 2015, AstraZeneca received FDA approval for Tagrisso, its drug for the treatment of T790M+ EGFRm+, tyrosine kinase inhibitor-resistant non-small cell lung cancer. A drug with this type of activity is known as a third-generation EGFR inhibitor. In 2018, Tagrisso’s label was expanded to include previously untreated patients with EGFRm+ non-small cell lung cancer. Tagrisso has been established as a new standard of care in the treatment of EGFRm+ non-small cell lung cancer and has now been approved in over 80 countries. Understanding the mechanism of acquired resistance following Tagrisso treatment is a key clinical question to inform the next treatment choice. A portion of EGFRm+ tyrosine kinase inhibitor-resistant patients and a portion of T790M+ EGFRm+ tyrosine kinase inhibitor-resistant patients progress because of MET gene amplification.

At the European Society of Medical Oncology Congress in 2018, AstraZeneca presented the first results on the acquired resistance spectrum detected in patient plasma samples after progression in the first-line (FLAURA) and second-line T790M (AURA3) Phase III studies. MET amplification was among the most frequent mechanisms of acquired resistance to Tagrisso, with 15% of patients in the FLAURA study and 19% of patients in the AURA3 study exhibiting MET amplification after treatment with Tagrisso. Ongoing research with tissue (biopsy) samples will further elucidate the incidence of MET and other mechanisms in the development of resistance to EGFR inhibitors.

Data presented in June 2017 at the American Society of Clinical Oncology by Harvard Medical School and Massachusetts General Hospital Cancer Center showed that about 30% (7/23 patients) of Tagrisso-resistant third-line non-small cell lung cancer patients harbor MET gene amplification based on analysis of tissue samples. This third-line patient population is generally heavily pre-treated and highly complex from a molecular analysis standpoint, with the study showing that more than half of the MET gene amplification patients also harbored additional genetic alterations, including EGFR gene amplification and K-Ras mutations.

As discussed in more detail below, we and AstraZeneca are studying savolitinib in combination with Tagrisso as a treatment choice for patients who have developed a resistance to tyrosine kinase inhibitors (primarily Tagrisso). The acceptance and uptake of Tagrisso indicates that the market potential for savolitinib in Tagrisso resistant, non-small cell lung cancer could be material.

TATTON study: Phase Ib/II expansion studies of savolitinib in combination with Tagrisso in non-small cell lung cancer EGFRm+ inhibitor refractory patients (Status: enrollment complete; NCT02143466)

The TATTON study is a global exploratory Phase I/Ib study in non-small cell lung cancer aiming to recruit patients with MET gene amplification who had progressed after prior treatment with EGFR inhibitors to support a decision on global Phase II/III registration strategy. This followed the completion of TATTON Part A, a Phase I study that established that a savolitinib and Tagrisso combination could be safe and well tolerated and also demonstrated preliminary signs of efficacy. In 11 evaluable patients who were MET positive, the objective response rate (the percentage of patients in the study who show either partial response (tumor measurement reduction of greater than 30%) or complete response) was 55% with a disease control rate of 100%.

As of data cut-off on March 29, 2019, a total of over 220 patients had received the savolitinib plus Tagrisso combination treatment across six TATTON treatment arms, Parts A, B1, B2, B3, C and D. Data for the B and D parts of the study were most recently presented at the European Society for Medical Oncology’s 2019 Asia meeting, and subsequently published in The Lancet Oncology in February 2020. As summarized below, the combination demonstrated an encouraging anti-tumor activity and an acceptable risk-benefit profile, regardless of dose.

First and second-generation EGFRm+ inhibitor refractory patients with acquired resistance driven by MET amplification

As published in The Lancet Oncology, TATTON Part B2 tested patients who were T790M negative with no prior third-generation EGFR tyrosine kinase inhibitor treatment. Of the 51 patients who received treatment, 33 patients had confirmed responses (65% of evaluable patients) with 45 patients experiencing disease control (88% of evaluable patients). The median progression-free survival was 9.0 months (95% confidence interval: 5.5-11.9 months). A 95% confidence interval means that there is a 95% chance that the results will be within the stated range. Pooled CTC grade 3 or above adverse events in part B of the study with greater than 5% incidence independent of causality were increased aspartate aminotransferase (7%), increased neutrophil count (7%), increased alanine aminotransferase (5%), pneumonia (5%) and dyspnea (5%).

66

TATTON Part B3 tested patients who were T790M positive with no prior third-generation EGFR tyrosine kinase inhibitor treatment. Of the 18 patients who received treatment, 12 patients had confirmed responses (67%) with 18 patients experiencing disease control (100%). The median progression-free survival was 11.0 months (95% confidence interval: 4.0 months – not reached). Pooled CTC grade 3 or above adverse events in part B of the study with greater than 5% incidence independent of causality were increased aspartate aminotransferase (7%), increased neutrophil count (7%), increased alanine aminotransferase (5%), pneumonia (5%) and dyspnea (5%).

In late 2017, the TATTON Part D study was initiated to study Tagrisso combined with a lower savolitinib dose (300 mg once daily) in the context of maximizing long-term tolerability of the combination for patients who could be in poor condition and/or on the combination for long periods of time. Of the 36 patients who received treatment, 23 patients had confirmed responses (64%) with 33 patients experiencing disease control (92%). The median progression-free survival was 9.1 months (95% confidence interval: 5.4-12.9 months). CTC grade 3 or above adverse events in Part D of the study with greater than 5% incidence independent of causality were pneumonia (12%), drug hypersensitivity (7%), diarrhea (5%), hypotension (5%) and generalized edema (5%). The TATTON Part D study demonstrated that a lower dose did not impair clinical efficacy, while maintaining a better tolerability profile. The results led to the selection of the 300 mg savolitinib plus 80 mg Tagrisso combination dose as the final regimen for the SAVANNAH study discussed below.

Tagrisso or another experimental third-generation EGFRm tyrosine kinase inhibitor refractory patients with acquired resistance driven by MET amplification

The TATTON Part B1 study enrolled non-small cell lung cancer patients that had progressed after treatment with a third-generation EGFR inhibitor as a result of MET gene amplification acquired resistance. These patients were recruited prior to the April 2018 FDA approval of Tagrisso as a first-line treatment and the January 2019 update to the National Comprehensive Cancer Network guidelines that state that Tagrisso is the preferred first-line treatment for patients with EGFR mutation regardless of pre-treatment T790M mutation status.

As published in The Lancet Oncology, savolitinib in combination with Tagrisso from the TATTON Part B1 study showed promising data. Of the 69 patients that had progressed on Tagrisso monotherapy and harbored MET amplification, there were 21 patients with confirmed responses (30%) with 52 patients experiencing disease control (75%). The median progression-free survival was 5.4 months (95% confidence interval: 4.1-8.0 months).

Overall the combination regimen of savolitinib 300 mg and Tagrisso was tolerable. In Part D of the study, 26% of patients discontinued savolitinib treatment due to adverse events and 14% of patients discontinued treatment for reasons other than adverse events, disease progression or death. Other approved treatments for non-small cell lung cancer such as Zykadia, Cyramza in combination with Taxotere, Keytruda, Opdivo, chemotherapy doublet (platinum and pemetrexed) and Taxotere monotherapy had discontinuations due to adverse events ranging from 10% to 15% and discontinuations due to reasons other than adverse events, disease progression or death ranging from 4% to 26%. CTC grade 3 or above adverse events in Part D of the study with greater than 5% incidence independent of causality were pneumonia (12%), drug hypersensitivity (7%), diarrhea (5%), hypotension (5%) and generalized edema (5%).

SAVANNAH study; Phase II study of savolitinib in combination with Tagrisso in non-small cell lung cancer Tagrisso-refractory EGFRm+ patients (Status: enrolling; NCT03778229)

Based on the encouraging results of the multiple TATTON studies, we and AstraZeneca have initiated a global Phase II study of savolitinib in combination with Tagrisso in EGFRm+ non-small cell lung cancer patients with MET gene amplification who have progressed following first or second-line Tagrisso therapy. The SAVANNAH study is a single-arm study in North and South America, Europe and Asia. Subject to positive clinical outcomes and regulatory interactions, the SAVANNAH study is designed to support potential NDA submission for savolitinib. We target to conduct an interim analysis in mid-2020 and complete enrollment by the end of 2020.

Savolitinib and Iressa Combination

In 2003, AstraZeneca received FDA approval for Iressa, a drug for the treatment of EGFRm+ tyrosine kinase inhibitor-resistant non-small cell lung cancer. Iressa is used in the treatment of patients with advanced EGFRm+ non-small cell lung cancer, and has been approved in over 64 countries. A portion of EGFRm+ tyrosine kinase inhibitor-resistant patients progress because of MET gene amplification. As discussed in more detail below, we and AstraZeneca are studying savolitinib in combination with Iressa as a second- and third-line treatment choice for patients who have developed a resistance to Iressa.

69

Phase Ib study of savolitinib in combination with Iressa in non-small cell lung cancer (second-line) EGFR inhibitor-refractory patients (Status: completed; NCT02374645)

At the 2017 World Conference on Lung Cancer, we presented Phase Ib proof-of-concept data assessing savolitinib (600 mg once daily) in combination with Iressa in patients in China with EGFRm+ advanced non-small cell lung cancer with centrally confirmed MET gene amplification who had progressed following first-generation EGFR inhibitor therapy. Preliminary results showed confirmed partial responses in 12 of 23 T790M− patients (52% objective response rate), as well as confirmed partial responses in two of 23 T790M+ patients (9% objective response rate). The 52% objective response rate in T790M− patients was as expected and similar to that recorded in the TATTON study Part B2 for this target patient population, indicating that for these patients Iressa might be the most cost-efficient combination partner for savolitinib. The low 9% objective response rate in T790M+ patients was also as expected, as Iressa does not effectively address T790M mutants. In terms of safety, the savolitinib plus Iressa combination dose was safe and well tolerated.

Kidney Cancer

The table below shows a summary of the clinical trials that we have recently completed or underway for savolitinib in kidney cancer patients.

Current and Recent Clinical Trials of Savolitinib in Kidney Cancer

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #
Savolitinib and Imfinzi	CALYPSO: Papillary RCC	UK/Spain	II	Interim – Presented at ASCO GU 2020	NCT02819596

Notes:     RCC = renal cell carcinoma; ASCO GU 2020 = the American Society of Clinical Oncology’s 2020 Genitourinary Cancers Symposium; VEGFR-TKI refractory = resistant to prior VEGFR tyrosine kinase inhibitor treatment; and Global = more than two countries.

Papillary renal cell carcinoma is the most common of the non-clear cell renal cell carcinomas representing about 14% of kidney cancer, with approximately half estimated to harbor MET-driven disease. No targeted therapies have been approved specifically for papillary renal cell carcinoma, although modest efficacy in non-clear cell renal cell carcinoma has been reported in sub-group analyses of broader renal cell carcinoma studies of VEGFR (e.g., Sutent) and mammalian target of rapamycin (e.g., Afinitor) tyrosine kinase inhibitors, with objective response rates of <10% and median progression-free survival in first-line setting of four to six months and second-line setting of only one to three months (ESPN study, Tannir N. M. et al.).

During an Australian Phase I study, our investigators noted positive outcomes among papillary renal cell carcinoma patients with a strong correlation to MET gene amplification status. Out of a total of eight papillary renal cell carcinoma patients in our Australia Phase I study who were treated with various doses of savolitinib, three achieved confirmed partial response. A further three of these eight papillary renal cell carcinoma patients achieved stable disease, which means patients without partial response but with a tumor measurement increase of less than 20%. This aggregate objective response rate of 38% was very encouraging for papillary renal cell carcinoma, which has no effective approved treatments. These responses were also durable as demonstrated by a patient who has been on the therapy for over 30 months and had tumor measurement reduction of greater than 85%. Importantly, the level of tumor response among these papillary renal cell carcinoma patients correlated closely with the level of MET gene amplification. The patients with consistent MET gene amplification across the whole tumor responded most to savolitinib, and with those patients with the highest level of MET gene amplification responding most to the treatment.

70

Recent data have emerged to show that papillary renal cell carcinoma responds to immunotherapy such as inhibitors of an immune checkpoint known as PD-1 used by cancer cells to avoid being attacked by the immune system. Preliminary data from the KEYNOTE-427 study (Cohort B) as presented by Merck & Co at the American Society of Clinical Oncology’s 2019 Genitourinary Cancers Symposium showed objective response in treatment naïve papillary renal cell carcinoma patients treated with the PD-1 inhibitor Keytruda was 25%. In the broader kidney cancer setting, combinations of PD-1 or PD-L1, with targeted therapies that demonstrated single agent effect have demonstrated additive benefits.

Savolitinib and Immunotherapy Combinations

Immunotherapy combinations are rapidly changing the treatment landscape in kidney cancer. Immune checkpoints such as PD-L1 are sometimes used by cancer cells to avoid being attacked by the immune system. As such, drugs that target these checkpoints are being developed or marketed as cancer treatments. Imfinzi is an anti-PD-L1 antibody owned by AstraZeneca. Anti-PD-L1 antibodies have been associated with clinical benefits in metastatic renal cell carcinoma, and MET dysregulation has been considered to play an important role in papillary renal cell carcinoma pathogenesis (including in our savolitinib Phase I and Phase II monotherapy studies) and is a mechanism of resistance against kinase inhibitors in clear cell renal cell carcinoma. Moreover, it is believed that the MET signaling pathway has a complex interplay with the immune system, including correlation with PD-L1 expression, immune suppression through angiogenesis and many other facets of the immune system. Our CALYPSO study discussed below aims to explore and potentially confirm this interplay.

CALYPSO study; Phase II study of savolitinib in combination with Imfinzi in both papillary renal cell carcinoma and clear cell renal cell carcinoma patients (status: dose expansion ongoing; NCT02819596)

The CALYPSO study is an investigator-initiated open-label Phase II study of savolitinib in combination with Imfinzi. The study is evaluating the safety and efficacy of the savolitinib and Imfinzi combination in both papillary renal cell carcinoma and clear cell renal cell carcinoma patients at sites in the U.K. and Spain.

Interim results of the papillary renal cell carcinoma cohort of the CALYPSO study were presented at the 2020 American Society of Clinical Oncology’s Genitourinary Cancers Symposium and showed encouraging efficacy across all patients, both MET+ and MET-. The interim CALYPSO data reported an objective response rate of 27% (11/41), while median progression-free survival was 4.9 months (95% confidence interval: 2.5-12.0 months). Median overall survival was 12.3 months (95% confidence interval: 5.8-21.3 months). For the study’s 27 previously untreated patients, the objective response rate was 33% (9/27). Tolerability was consistent with established single agent safety profiles. There were 13 treatment related CTC grade 3 or above adverse events that occurred in more than three patients, with edema (10%), nausea (5%) and transaminitis (5%) being most frequent. We and AstraZeneca continue to explore development of the savolitinib-Imfinzi combination in papillary renal cell carcinoma patients.

Savolitinib Monotherapy

Phase II study of savolitinib monotherapy in papillary renal cell carcinoma (Status: completed; NCT02127710)

In early 2017, we presented the results of our global Phase II study in papillary renal cell carcinoma at the American Society of Clinical Oncology’s Genitourinary Cancers Symposium and subsequently published these results in the Journal of Clinical Oncology. This Phase II study, conducted in the United States, Canada and Europe, was the largest and most comprehensive clinical study in papillary renal cell carcinoma ever conducted. Of 109 patients treated with savolitinib, papillary renal cell carcinoma was MET driven in 44 patients (40%), MET independent in 46 patients (42%) and MET status unknown in 19 patients (17%). The objective response rate based on confirmed partial responses in all patients was 7% (8/109). MET-driven papillary renal cell carcinoma was strongly associated with encouragingly durable response to savolitinib with an objective response rate in the MET-driven group of 18% (8/44) as compared to 0% (0/46) in the MET independent group (p=0.002). P-value is a measure of the probability of obtaining the observed sample results, with a lower value indicating a higher degree of statistical confidence in these studies. Median progression-free survival for patients with MET-driven and MET-independent papillary renal cell carcinoma patients was 6.2 months (95% confidence interval: 4.1-7.0) and 1.4 months (95% confidence interval: 1.4-2.7), respectively (hazard ratio=0.33; 95% confidence interval: 0.20-0.52; p<0.0001). Hazard ratio is the  probability of an event (such as disease progression or death) occurring in the treatment arm divided by the probability of the event occurring in the control arm of a study, with a ratio of less than one indicating a lower probability of an event occurring for patients in the treatment arm. Savolitinib had a disease control rate of 73% in the MET-driven group and 28% in the MET independent group. Savolitinib was well tolerated, with no reported treatment related CTC grade 3 or above adverse events with greater than 5% incidence. Total aggregate savolitinib treatment-related CTC grade 3 or above adverse events occurred in just 19% of patients.

SAVOIR study; Phase III study of savolitinib monotherapy in papillary renal cell carcinoma (Status: enrollment suspended; NCT03091192)

We initiated the SAVOIR study in June 2017. The SAVOIR study was designed to be a global Phase III, open-label, randomized, controlled trial evaluating the efficacy and safety of savolitinib (600 mg once daily) compared with Sutent in patients with MET-driven, unresectable, locally advanced or metastatic papillary renal cell carcinoma. MET status was confirmed by the novel targeted next-generation sequencing assay developed for savolitinib. Patients were randomized in a 1:1 ratio to receive either treatment with savolitinib, or treatment with Sutent. The primary endpoint for efficacy in the SAVOIR study was median progression-free survival, with secondary endpoints of overall survival, objective response rate, duration of response, best percentage change in tumor size, disease control rate, and safety and tolerability. Furthermore, to further understand the role of MET-driven disease in papillary renal cell carcinoma, we conducted a global molecular epidemiology study, which screened, using our companion diagnostic, archived tissue samples from papillary renal cell carcinoma patients to identify MET-driven disease. Historical medical records from these patients were then used to determine if MET-driven disease is predictive of worse outcome, in terms of progression-free survival and overall survival, in papillary renal cell carcinoma patients.

72

In December 2018, SAVOIR enrollment was terminated. Data from the approximately 60 patients randomized in the SAVOIR study prior to termination matured during 2019 and is expected to be presented at an upcoming scientific conference in mid-2020. Based on these data, we and AstraZeneca are actively evaluating the opportunity to restart clinical trials of savolitinib as a monotherapy for the treatment of papillary renal cell carcinoma.

Gastric Cancer

The table below shows a summary of our clinical trials for savolitinib in gastric cancer patients.

Note:     Savolitinib mono = savolitinib monotherapy trial.

Phase II gastric cancer studies have been completed in China and in South Korea. A total of over 1,000 gastric cancer patients had been screened in these studies and those patients with confirmed MET-driven disease were treated.

Phase Ib/II study of savolitinib monotherapy in MET amplified gastric cancer in China (Status: completed; NCT01985555)

Preliminary results of the China study were presented at the 2017 Chinese Society of Clinical Oncology for the efficacy evaluable MET gene amplified patients. Based on confirmed and unconfirmed partial responses, the objective response rate was 43% (3/7) and disease control rate was 86% (6/7), with objective response rate of 14% (3/22) and disease control rate of 41% (9/22) among the overall efficacy evaluable aberrant MET set of patients with MET amplification (n=7) and MET overexpression (n=15). As of data cut-off, the longest duration of treatment was in excess of two years. Savolitinib monotherapy was determined to be safe and well tolerated in patients with advanced gastric cancer. CTC grade 3 or above treatment emergent adverse events with greater than 5% incidence included abnormal hepatic function in 13% (4/31), gastrointestinal bleeding or decreased appetite in 10% (3/31 each), and diarrhea or gastrointestinal perforation in 6% (2/31 each). This China study concluded that savolitinib monotherapy demonstrated promising anti-tumor efficacy in gastric cancer patients with MET gene amplification, and that the potential benefit to these patients warranted further exploration, with enrollment continuing.

VIKTORY Phase II study of savolitinib monotherapy in MET amplified gastric cancer in South Korea (Status: completed; NCT02449551)

The VIKTORY study is a biomarker-based, Phase II umbrella trial in gastric cancer conducted by the Samsung Medical Center in South Korea. Patients were allocated to one of 12 biomarker-driven arms, based on a master screening protocol with tissue-based molecular analyses. Patients that tested positive for MET amplification or overexpression were treated with either savolitinib monotherapy or a combination of savolitinib and Taxotere. A total of 715 gastric cancer patients were successfully sequenced and MET amplification was observed in 3.5% of these patients (25/715). Of the 10 associated clinical trials under the VIKTORY umbrella, the highest objective response rate was observed in the MET amplification arm in patients treated with savolitinib monotherapy, which reported an objective response rate of 50% (10/20, 95% confidence interval: 28.0-71.9) and met pre-specified 6-week progression-free survival rates.

The VIKTORY study investigators have concluded that encouraging clinical efficacy of savolitinib in MET-amplified gastric cancer warrants further study.

VIKTORY Phase II studies of savolitinib in combination with Taxotere in MET amplified or overexpression gastric cancer in South Korea (Status: enrollment directed to savolitinib monotherapy arm; NCT02447406/NCT02447380)

In a Phase I dose-finding trial, 17 patients were enrolled including seven gastric cancer patients, five melanoma patients, three sarcoma patients and two rectal cancer patients. Most of the patients (14/17) were heavily pretreated (third line or greater). The combination therapy demonstrated promising antitumor activity with durable responses in MET amplified gastric cancer patients. One gastric cancer patient with both MET overexpression and MET amplification achieved a durable partial response for 297 days, and another MET amplified gastric cancer patient achieved stable disease for 86 days. While the savolitinib and Taxotere combination was well tolerated, the VIKTORY study investigators decided to stop enrollment in the two combination cohorts in order to direct patients to the savolitinib monotherapy arm of the VIKTORY study as discussed above.

Other exploratory studies

The table below shows a summary of the clinical study that is underway for savolitinib in prostate cancer patients.

Phase II study of savolitinib monotherapy in metastatic castration-resistant prostate cancer (Status: enrolling; NCT03385655)

A Phase II study sponsored by the Canadian Cancer Trials Group is enrolling patients to determine the effect of savolitinib on prostate-specific antigen decline and time to prostate-specific antigen progression. The study will assess the objective response rate as determined by Response Evaluation Criteria in Solid Tumors, or RECIST, revision version 1.1, a set of published rules that define when tumors improve, stay the same or worsen during treatment. It will also evaluate the safety and toxicity profile of savolitinib in metastatic castration-resistant prostate cancer patients and identify potential predictive and prognostic factors. The umbrella study targets to enroll around 500 patients into four treatment arms based on molecular status, with one treatment arm being patients with MET-driven disease receiving savolitinib. High levels of MET overexpression can be prevalent in prostate cancer patients.

Phase II study of savolitinib monotherapy in metastatic colorectal cancer (Status: enrolling; NCT03592641)

This study is sponsored by the National Cancer Institute and targets to screen up to 150 patients in order to enroll approximately 15 patients with MET amplified metastatic colorectal cancer. The primary objective of the study is objective response rate. Secondary objectives include additional measures of clinical efficacy, safety, and tolerability.

Partnership with AstraZeneca

In December 2011, we entered into a global licensing, co-development, and commercialization agreement for savolitinib with AstraZeneca. As noted above, given the complexity of many of the signal transduction pathways and resistance mechanisms in oncology, the industry is increasingly studying combinations of targeted therapies (tyrosine kinase inhibitors, monoclonal antibodies and immunotherapies) and chemotherapy as potentially the best approach to treating this complex and constantly mutating disease. Based on savolitinib showing early clinical benefit as a highly selective MET inhibitor in a number of cancers, in August 2016 we and AstraZeneca amended our global licensing, co-development, and commercialization agreement for savolitinib. We believe that AstraZeneca’s portfolio of proprietary targeted therapies is well suited to be used in combinations with savolitinib, and we are studying combinations with Iressa (EGFRm+), Tagrisso (T790M+) and Imfinzi (PD-L1). These combinations of multiple global first-in-class compounds are difficult to replicate, and we believe represent a significant opportunity for us and AstraZeneca.

2.    Fruquintinib VEGFR 1, 2 and 3 Inhibitor

Fruquintinib (also known as HMPL-013) is a VEGFR inhibitor that we believe is highly differentiated due to its superior kinase selectivity compared to other small molecule VEGFR inhibitors, which can be prone to excessive off-target toxicities. Fruquintinib’s selectivity on VEGFR 1, 2 and 3 results in fewer off-target toxicities, thereby allowing for better target coverage, as well as possible use in combination with other agents such as chemotherapies, targeted therapies and immunotherapies.

We believe these are meaningful points of differentiation compared to other approved small molecule VEGFR inhibitors such as Sutent, Nexavar and Stivarga, and can potentially significantly expand the use and market potential of fruquintinib. Consequently, we believe that fruquintinib has the potential to become the global best-in-class selective small molecule VEGFR inhibitor for many types of solid tumors.

We received full approval for launch of fruquintinib (under the brand name Elunate) in colorectal cancer in September 2018. In partnership with Eli Lilly, we launched fruquintinib in China in late November 2018. Elunate is indicated for the treatment of patients with metastatic colorectal cancer that have been previously treated with fluoropyrimidine, oxaliplatin and irinotecan, including those who have previously received anti-VEGF therapy and/or anti-EGFR therapy (Ras wild type).  We manufacture all commercial supplies of Elunate in our factory in Suzhou. For more information regarding the Elunate product launch, see “—Overview of Elunate Commercial Launch.”

Mechanism of Action

During the development of cancer, tumors at an advanced stage can secrete large amounts of VEGF, a protein ligand, to stimulate formation of excessive vasculature (angiogenesis) around the tumor in order to provide greater blood flow, oxygen, and nutrients to fuel the rapid growth of the tumor. Since essentially all solid tumors require angiogenesis to progress beyond a few millimeters in diameter, antiangiogenesis drugs have demonstrated benefits in a wide variety of tumor types. VEGF and other ligands can bind to three VEGF receptors, VEGFR 1, 2 and 3, each of which has been shown to play a role in angiogenesis. Therefore, inhibition of the VEGF/VEGFR signaling pathway can act to stop the growth of the vasculature around the tumor and thereby starve the tumor of the nutrients and oxygen it needs to grow rapidly.

This therapeutic strategy has been well validated with several first-generation VEGF inhibitors having been approved globally since 2005 and 2006. These include both small molecule multi-kinase inhibitor drugs such as Nexavar and Sutent as well as monoclonal antibodies such as Avastin. The success of these drugs validated VEGFR inhibition as a new class of therapy for the treatment of cancer.

Fruquintinib Pre-clinical Evidence

Pre-clinical trials have demonstrated that fruquintinib is a highly selective VEGFR 1, 2 and 3 inhibitor with high potency and low cell toxicity at the enzymatic and cellular levels. In a kinase selectivity screening, fruquintinib was found to be approximately 250 times more selective to VEGFR 3 than to the next non-VEGFR kinase.

As a result of off-target side effects, existing VEGFR inhibitors are often unable to be dosed high enough to completely inhibit VEGFR, the intended target. In addition, the complex off-target toxicities resulting from inhibition of multiple signaling pathways are often difficult to be managed in clinical practice. Combining such drugs with chemotherapy can lead to severe toxicities that can cause more harm than benefit to patients. To date, the first generation VEGFR tyrosine kinase inhibitors have been rarely used in combination with other therapies, thereby limiting their potential. Because of the potency and selectivity of fruquintinib, we believe that it has the potential to be safely combined with other oncology drugs, which could significantly expand its clinical potential.

Fruquintinib Clinical Trials

Studies in Colorectal Cancer

The table below shows a summary of the clinical trials we have recently completed, are underway or are in planning for fruquintinib in colorectal cancer patients. We have two additional trials in progress for fruquintinib in colorectal cancer in combination with a checkpoint inhibitor as discussed in more detail below under “– Fruquintinib Combinations with Checkpoint Inhibitors.”

FRESCO study; Phase III study of fruquintinib monotherapy in third-line colorectal cancer (Status: completed and product launched in November 2018; NCT02314819)

In 2014, we initiated the FRESCO study, which is a randomized, double-blind, placebo-controlled, multi-center, Phase III pivotal trial in China in patients with locally advanced or metastatic colorectal cancer who have failed at least two prior systemic antineoplastic therapies, including fluoropyrimidine, Eloxatin and Camptosar. No drugs had been approved in third-line colorectal cancer in China with best supportive care being the general standard of care. This study followed a Phase II proof-of-concept trial in third-line colorectal cancer that met its primary endpoint of progression-free survival in 2014.

Enrollment was completed in May 2016, and 519 patients were screened. The intent-to-treat population of 416 patients was randomized at a 2:1 ratio to receive either: 5 mg of fruquintinib orally once daily, on a three-weeks-on/one-week-off cycle, plus best supportive care (278 patients) or placebo plus best supportive care (138 patients). Randomization was stratified for prior anti-VEGF therapy and K-RAS gene status. The trial concluded in January 2017.

In June 2017, we presented the results of the FRESCO study in an oral presentation during the American Society of Clinical Oncology Annual Meeting. Results showed that FRESCO met all primary and secondary endpoints including significant improvements in overall survival and progression-free survival with a manageable safety profile and lower off-target toxicities compared to other targeted therapies.

The primary endpoint of median overall survival was 9.30 months (95% confidence interval: 8.18-10.45 months) in the fruquintinib group versus 6.57 months (95% confidence interval: 5.88-8.11 months) in the placebo group, with a hazard ratio of 0.65 (95% confidence interval: 0.51-0.83; two-sided p<0.001).

77

The secondary endpoint of median progression-free survival was 3.71 months (95% confidence interval: 3.65-4.63 months) in the fruquintinib group versus 1.84 months (95% confidence interval: 1.81-1.84 months) in the placebo group, with a hazard ratio of 0.26 (95% confidence interval: 0.21-0.34; two-sided p<0.001). Significant benefits were also seen in other secondary endpoints. The disease control rate in the fruquintinib group was 62% versus 12% for placebo (p<0.001), while the objective response rate based on confirmed responses was 5% versus 0% for placebo (p=0.012).

While it is difficult to directly evaluate and compare clinical results across separate trials, data from the FRESCO study compare favorably to the data from the CONCUR study, a Phase III study of Stivarga monotherapy in colorectal cancer conducted in Asia, and the CORRECT study, a global Phase III study of Stivarga in colorectal cancer. In particular, in the Chinese patient subgroup of the CONCUR study, Stivarga had a disease control rate of 46% versus 7% in the placebo group. Median progression-free survival was 2.0 months in the Stivarga group versus 1.7 months in the placebo group, and median overall survival was 8.4 months in the Stivarga group versus 6.2 months in the placebo group. In the CORRECT study, Stivarga had a disease control rate of 41% versus 15% in the placebo group. Median progression-free survival was 1.9 months in the Stivarga group versus 1.7 months for the placebo group, and median overall survival was 6.4 months in the Stivarga group versus 5.0 in the placebo group.

In terms of safety, results showed that fruquintinib had a manageable safety profile with lower off-target toxicities compared to other VEGFR tyrosine kinase inhibitors. Of particular interest was that the CTC grade 3 or above hepatotoxicity was similar for the fruquintinib group as compared to the placebo group, which is in contrast to Stivarga which was markedly higher and often difficult to manage in the Chinese patient population in the CONCUR study. Adverse events led to dose interruptions in 69% of patients in the Chinese patient subgroup of the CONCUR study, compared to 35% in the FRESCO study. The most frequently reported fruquintinib-related CTC grade 3 or above adverse events included hypertension (21%), hand-foot skin reaction (11%), proteinuria (3%) and diarrhea (3%), all possibly associated with VEGFR inhibition. No other CTC grade 3 or above adverse events exceeded 2% in the fruquintinib population, including hepatic function adverse events such as elevations in bilirubin (1%), alanine aminotransferase (<1%) or aspartate aminotransferase (<1%).

78

In terms of tolerability, dose interruptions or reductions occurred in only 35% and 24% of patients in the fruquintinib arm, respectively, and only 15% of patients discontinued treatment of fruquintinib due to adverse events versus 6% for placebo. The FRESCO study was published in the Journal of the American Medical Association in June 2018.

Subgroup analysis

In June 2018, a further subgroup analysis of data from the FRESCO Phase III study was presented during the American Society of Clinical Oncology Annual Meeting. This analysis explored possible effects of prior target therapy on the efficacy and safety of fruquintinib by analyzing the subgroups of patients with prior target therapy and those without prior target therapy.

Results showed that the benefits of fruquintinib were generally consistent across all subgroups. Among a total of 278 fruquintinib-treated patients, 111 had received prior target therapy while 55 of the 138 placebo-treated patients had received prior target therapy. In the prior target therapy subgroup, fruquintinib significantly prolonged overall survival and progression-free survival. Median overall survival was 7.69 months for patients treated with fruquintinib and 5.98 months for placebo (hazard ratio = 0.63; p = 0.012). Median progression-free survival was 3.65 months for patients treated with fruquintinib and 1.84 months for placebo (hazard ratio = 0.24; p < 0.001).

Among these 278 patients, the results showed that a subgroup of 84 patients who had received prior anti-VEGF treatment also benefited from fruquintinib. In this subgroup, the median overall survival was 7.20 months for fruquintinib and 5.91 months for placebo (hazard ratio = 0.68; p=0.066) and the median progression-free survival was 3.48 months for fruquintinib and 1.84 months for placebo (hazard ratio = 0.24; p < 0.001).

In the subgroup of 250 patients without prior target therapy, the median overall survival was 10.35 months for 167 patients treated with fruquintinib and 6.93 months for 83 patients treated with placebo (hazard ratio = 0.63; p = 0.003), and the median progression-free survival for patients treated with fruquintinib was 3.81 months versus 1.84 months for placebo (hazard ratio = 0.28; p < 0.001).

Additional data showed that there were no observed cumulative CTC grade 3 or above treatment-emergent adverse events in the subgroup of patients with prior target therapy. The CTC grade 3 or above treatment-emergent adverse event rates of fruquintinib were similar in the subgroups with prior target therapy (61.3%) and without prior target therapy (61.1%). This subgroup analysis is consistent with the previously reported results from the FRESCO study’s intent-to-treat population.

The results of this analysis showed that fruquintinib had clinically meaningful benefits in third-line metastatic colorectal cancer patients regardless of prior target therapy without observed cumulative toxicity.

Quality-adjusted survival analysis

At the 2018 American Society of Clinical Oncology Annual Meeting, an analysis was presented that aimed to compare the quality-adjusted survival between the two arms of the FRESCO study using quality-adjusted time without symptoms or toxicity, or Q-TWiST, methodology and to investigate the Q-TWiST benefit of fruquintinib treatment among subgroups. Q-TWiST is a tool to evaluate relative clinical benefit-risk from a patient’s perspective and has been widely used in oncology treatment assessment. The survival time for each patient was divided into three portions: time with CTC grade 3 or above toxicity before progression, time without symptoms or CTC grade 3 or above toxicity, and time from progression or relapse until death or end of follow-up.

Patients treated with fruquintinib had longer Q-TWiST periods compared to patients treated with placebo. Q-TWiST benefits were observed regardless of prior lines of chemotherapy and prior anti-VEGF or anti-EGFR targeted therapy. The relative improvement of Q-TWiST with fruquintinib represents a clinically important quality-of-life benefit for metastatic colorectal cancer patients.

Supported by data from the successful FRESCO study, we submitted an NDA for fruquintinib in June 2017. Fruquintinib was subsequently awarded priority review status by the NMPA in view of its clinical value in September 2017, and in September 2018, the NMPA approved fruquintinib for the treatment of patients with advanced colorectal cancer and was launched in November 2018. For more information regarding the Elunate product launch, see “—Overview of Elunate Commercial Launch.”

Phase Ib study of fruquintinib monotherapy in metastatic colorectal cancer (Status: enrolling; NCT03251378)

We are conducting a multi-center, open-label, Phase Ib clinical study to evaluate the safety, tolerability and pharmacokinetics of fruquintinib in U.S. patients, which established the U.S. recommended Phase II dose to be 5 mg, the same as that in China.  This dose is being further evaluated in patients with metastatic colorectal cancer.

80

Phase III study of fruquintinib monotherapy in metastatic colorectal cancer (Status: in planning)

We intend to initiate a Phase III registration study, known as the FRESCO2 study, in the United States, Europe and Japan in metastatic colorectal cancer and breast cancer patients. By mid-2020, we expect to have met with regulatory authorities in the United States, Europe and Japan. Subject to regulatory discussions, FRESCO2 is expected to start enrolling patients in mid-2020. Based on our agreement with the FDA, both the FRESCO and FRESCO 2 studies, if positive, will support our NDA application.

Gastric Cancer

Advanced gastric cancer is a major medical need, particularly in Asian populations, with limited treatment options for patients who have failed first-line standard chemotherapy with 5-fluorouracil and platinum doublets. There were approximately 442,300 new cases of gastric cancer in China in 2018. The table below shows a summary of the clinical study we have underway for fruquintinib in gastric cancer patients.

Note:    2L = second line.

FRUTIGA study; Phase III study of fruquintinib in combination with Taxol in gastric cancer (second-line) (Status: first interim analysis reported; NCT03223376)

In October 2017, we initiated the FRUTIGA study, a pivotal Phase III clinical trial of fruquintinib in combination with Taxol for the treatment in advanced gastric or gastroesophageal junction adenocarcinoma patients in China. This randomized, double-blind, placebo-controlled, multi-center trial is being conducted in patients with advanced gastric cancer who have progressed after first-line standard chemotherapy. Over 540 patients are expected to be enrolled in the FRUTIGA study to evaluate the efficacy and safety of fruquintinib combined with paclitaxel compared with paclitaxel monotherapy for second-line treatment of advanced gastric or gastroesophageal junction adenocarcinoma. The trial will enroll patients with disease that has been confirmed through histology or cytology and who did not respond to first-line standard chemotherapy containing platinum and fluorouracil. All subjects will receive fruquintinib or placebo combined with paclitaxel. Patients will be randomized at a 1:1 ratio and stratified according to factors such as stomach versus gastroesophageal junction tumors and ECOG performance status, a scale established by the Eastern Cooperative Oncology Group which determines ability of patient to tolerate therapies in serious illness, specifically for chemotherapy.

The primary efficacy endpoint is overall survival. Secondary efficacy endpoints include progression-free survival, objective response rate, disease control rate, duration of response and quality-of-life score (EORTC QLQ-C30, version 3.0). Biomarkers related to the antitumor activity of fruquintinib will also be explored.

In April 2019, we conducted an interim analysis of the FRUTIGA study for futility. The analysis evaluated progression-free survival and overall survival trends after six months of therapy for the first 100 patients recruited into the study. The independent data monitoring committee recommended to continue the study without changes. We expect to conduct a second interim analysis in mid-2020 and complete enrollment of the study in 2020.

Non-small Cell Lung Cancer

The table below shows a summary of the clinical trials we have recently completed for fruquintinib in non-small cell lung cancer patients.

Phase II study of fruquintinib monotherapy in third-line non-small cell lung cancer (Status: completed; NCT02590965)

In 2014, we initiated a Phase II randomized, double-blind, placebo-controlled, multi-center study of fruquintinib versus placebo among patients with advanced non-squamous non-small cell lung cancer who failed two lines of chemotherapy in China. By early March 2015, enrollment had been completed with a total of 91 patients randomized to 5 mg of fruquintinib orally once per day, on a 3-weeks-on/1-week-off regimen plus best supportive care, or placebo plus best supportive care at a 2:1 ratio.

In 2015, we reported that fruquintinib had clearly met its primary endpoint of superior median progression-free survival versus placebo in this study, and in December 2016, we reported the full data from this study at the 2016 World Conference on Lung Cancer, which showed median progression-free survival of 3.8 months for the fruquintinib group compared with 1.1 months for the placebo group (hazard ratio=0.34; 95% confidence interval: 0.20-0.57; p<0.001), an objective response rate based on confirmed partial responses of 13% for the fruquintinib group compared with 0% for the placebo group (p=0.041), and a 48% increase in disease control rate for the fruquintinib group compared with  the placebo group (p<0.001). All were assessed by blinded independent clinical review. Fruquintinib was well tolerated with the only treatment related CTC grade 3 or above adverse events with greater than 5% incidence being hypertension (8%). The results of the study were published in the April 2018 issue of the Journal of Clinical Oncology.

FALUCA study; Phase III study of fruquintinib monotherapy in third-line non-small cell lung cancer (Status: completed; NCT02691299)

Following a positive Phase II study comparing fruquintinib with placebo in advanced non-squamous non-small cell lung cancer patients who have failed two prior systemic chemotherapies, or third-line non-small cell lung cancer, we initiated a Phase III registration study, the FALUCA study, in late 2015. In February 2018, we completed enrollment of the FALUCA study in China, in which a total of 527 patients were randomized at a 2:1 ratio to receive either 5 mg of fruquintinib orally once daily, on a 3-weeks-on/1-week-off cycle plus best supportive care, or placebo plus best supportive care. In November 2018, we announced that the trial did not meet the primary endpoint to demonstrate a statistically significant increase in overall survival compared to placebo. However, fruquintinib demonstrated a statistically significant improvement in all secondary endpoints including progression-free survival, objective response rate, disease control rate and duration of response as compared to the placebo. The safety profile of the trial was in line with that observed in prior clinical trials.

Full analysis of the study was presented at the 2019 World Conference on Lung Cancer. The investigator concluded that post-progress treatment was a confounding factor and contributed to fruquintinib not showing overall survival benefit despite meeting secondary efficacy endpoints with p-values less than 0.001 such as progression-free survival (3.68 months for fruquintinib vs. 0.99 months for placebo), overall response rate (14% for fruquintinib vs. 1% for placebo) and disease control rate (67% for fruquintinib vs. 25% for placebo). Median overall survival in the fruquintinib patients was 8.74 months vs. 10.38 months for placebo; however, among patients who did not receive subsequent therapy after their disease progressed, which accounted for 71% of the fruquintinib patients and 66% of placebo patients, median overall survival was 7.00 months for fruquintinib and 5.06 months for placebo (hazard ratio = 0.64; p=0.010). Fruquintinib was well tolerated with treatment related CTC grade 3 or above adverse events with greater than 5% incidence being hypertension (21%) and hand-foot syndrome (11%).

Fruquintinib’s unique safety and tolerability profile, resulting from its high kinase selectivity, combined with better flexibility to manage treatment emergent toxicities due to its shorter half-life than monoclonal antibody antiangiogenesis therapies, makes it a suitable potential combination partner for EGFR tyrosine kinase inhibitors.

Phase II study of fruquintinib in combination with Iressa in first-line non-small cell lung cancer (Status: completed; NCT02976116)

We have completed a multi-center, single-arm, open-label, dose-finding Phase II study of fruquintinib in combination with Iressa in China in the first-line setting for patients with advanced or metastatic non-small cell lung cancer with EGFR activating mutations. We enrolled 50 patients in this study with the objective of evaluating the safety and tolerability as well as the efficacy of the combination therapy.

Final results from this Phase II study were presented at European Society for Medical Oncology’s 2019 Asia meeting, reporting promising efficacy with an objective response rate of 72% and median profession-free survival of 14.7 months (95% confidence interval: 12.5-21.2 months).

Fruquintinib exhibited an acceptable safety profile, which we believe results from its high kinase selectivity and versatility of administration. A dose of 4 mg of fruquintinib in combination with 250 mg of Iressa was better tolerated than a 5 mg dose without compromising efficacy. There were 28 (56%) CTC grade 3 or above treatment emergent adverse events, including increased alanine aminotransferase (22%), increased aspartate aminotransferase (10%), proteinuria (8%) and increased r-GT (6%). Serious adverse events occurred in 18% of the patients in the study.

Note:   CRC = colorectal cancer; NSCLC = non-small cell lung cancer; and TBD = to be determined.

In November 2018, we entered into two collaboration agreements to evaluate the safety, tolerability and efficacy of fruquintinib in combination with checkpoint inhibitors. These include a global collaboration with Innovent to evaluate the combination of fruquintinib with Innovent’s Tyvyt, a PD-1 monoclonal antibody approved in China, and a collaboration in China with Genor to evaluate the fruquintinib combination with genolimzumab, a PD-1 monoclonal antibody being developed by Genor. We are now approaching completion of the Phase I dose-finding study in China of fruquintinib in combination with Tyvyt and a U.S. Phase I is in planning. Phase I development of fruquintinib in combination with genolimzumab is also underway.

Fruquintinib Exploratory Development

We are conducting multiple Phase Ib expansion cohorts in the United States to explore fruquintinib in colorectal cancer and breast cancer. In China, Eli Lilly is also preparing to support investigator-initiated studies in multiple solid tumor settings.

Overview of Elunate Commercial Launch

Fruquintinib capsules, sold under the brand name Elunate, were approved for marketing in China by the NMPA in September 2018 and commercially launched in late November 2018. Elunate is for the treatment of patients with metastatic colorectal cancer that have been previously treated with fluoropyrimidine, oxaliplatin and irinotecan, including those who have previously received anti-VEGF therapy and/or anti-EGFR therapy (RAS wild type).

Starting on January 1, 2020, Elunate was included on China’s National Reimbursement Drug List at a 63% discount to its initial retail price, paving the way to significantly broaden access for advanced colorectal cancer patients and rapidly build penetration in China over the coming years.

The revenue we generate from Elunate is comprised of royalty revenue and revenue from the sales of Elunate to Eli Lilly which we manufacture and sell at cost. In 2019, we generated $10.8 million in total revenue from Elunate, of which $2.7 million was royalty revenue and $8.1 million was revenue from sales to Eli Lilly.

Partnership with Eli Lilly

In October 2013, we entered into a license and collaboration agreement with Eli Lilly in order to accelerate and broaden our fruquintinib development program in China. As a result, we were able to quickly expand the clinical development of fruquintinib in three indications with major unmet medical needs in China: colorectal cancer, non-small cell lung cancer and gastric cancer, as discussed above. In December 2018, we amended our license and collaboration agreement with Eli Lilly. This amendment gives us, among other things, all planning, execution and decision making responsibilities for life cycle indication development of fruquintinib in China. It also gives us the promotion and distribution rights for fruquintinib in provinces that represent 30% (or 40% if certain additional criteria are met) of sales of fruquintinib in China upon the achievement of a non-fruquintinib related Eli Lilly commercial action. Support from Eli Lilly has also helped us to establish our own manufacturing (formulation) facility in Suzhou, China, which now produces clinical and commercial supplies of fruquintinib.

3.    Surufatinib VEGFR 1, 2 and 3, FGFR1 and CSF-1R Inhibitor

Surufatinib is an oral small molecule angio-immuno kinase inhibitor targeting VEGFR and FGFR, which both inhibit angiogenesis, and CSF-1R, which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells. Its unique angio-immuno kinase profile seems to support surufatinib could help improve the anti-tumor activity of PD-1 antibodies.

Surufatinib is the first oncology candidate that we have taken through proof-of-concept in China and expanded globally ourselves. Surufatinib is in proof-of-concept clinical trials in the United States, successfully completed two late-stage clinical trials, is in further late-stage clinical trials in China and is expected to start late-stage trials in the United States and Europe as a monotherapy. Furthermore, it is being investigated in combination with PD-1 inhibitors.

Mechanism of Action

Both VEGFR and FGFR signaling pathways can mediate tumor angiogenesis. CSF-1R plays an important role in the functions of macrophages. Recently, the roles in increasing tumor immune evasion of VEGFR, FGFR in regulation of T cells, tumor-associated macrophages and myeloid-derived suppressor cells have been demonstrated. Therefore, blockade of tumor angiogenesis and tumor immune evasion by simultaneously targeting VEGFR 1, 2 and 3, FGFR1 and CSF-1R kinases may represent a promising approach for oncology therapy.

Surufatinib Pre-clinical Evidence

Surufatinib inhibited VEGFR 1, 2, and 3, FGFR1 and CSF-1R kinases with IC₅₀ in a range of 1 nM to 24 nM. It also strongly blocked VEGF-induced VEGFR2 phosphorylation in HEK293 cells and CSF-1R phosphorylation in RAW264.7 cells with an IC₅₀ of 2 nM and 79 nM, respectively. Surufatinib also reduced VEGF- or FGF-stimulated human umbilical vein endothelial cell proliferation with an IC₅₀ < 50 nM. In animal studies, a single oral dose of surufatinib inhibited VEGF-stimulated VEGFR2 phosphorylation in lung tissues of nude mice in an exposure-dependent manner. Furthermore, elevation of FGF23 levels in plasma 24 hours post dosing suggested suppression of FGFR signaling.

Surufatinib demonstrated potent tumor growth inhibition in multiple human xenograft models and decreased cluster of differentiation 31 expression remarkably, suggesting strong inhibition on angiogenesis through VEGFR and FGFR signaling. In a syngeneic murine colon cancer model, surufatinib demonstrated moderate tumor growth inhibition after single-agent treatment. Flow cytometry and immunohistochemistry analysis revealed an increase of certain T cells and a significant reduction in certain tumor-associated macrophages, including CSF-1R mutation positive tumor-associated macrophages in tumor tissue, indicating surufatinib has a strong effect on CSF-1R. Interestingly, a combination of surufatinib with a PD-L1 antibody resulted in enhanced anti-tumor effect. These results suggested that surufatinib has a strong effect in modulating angiogenesis and cancer immunity.

Surufatinib Clinical Trials

We currently have various clinical trials of surufatinib ongoing or expected to begin in the near term in patients with neuroendocrine tumors and biliary tract cancer and in combination with checkpoint inhibitors.

Neuroendocrine tumors

Neuroendocrine tumors begin in the specialized cells of the body’s neuroendocrine system. Cells have traits of both hormone-producing endocrine cells and nerve cells. Neuroendocrine tumors are found throughout the body’s organ system and have complex and fragmented epidemiology with about 40-60% of neuroendocrine tumors originating in the gastrointestinal tract and pancreas, 20-30% in the lung or bronchus, and a further 20%-30% in other organs or unknown origins.

In China, there were about 67,600 newly diagnosed NET patients in 2018 and, while no China prevalence data exists, we believe that there could be over 400,000 patients living with the disease.

Neuroendocrine tumors can be functional, releasing hormones and peptides that cause symptoms like diarrhea and flushing, or non-functional with no symptoms. Early-stage neuroendocrine tumors, which are often functional, can be treated with somatostatin analogue subcutaneous injections, which are approved and reimbursed in China and alleviate symptoms and slow neuroendocrine tumor growth, but have limited tumor reduction efficacy.

86

Advanced neuroendocrine tumors grow more quickly. In China, Sutent is approved in pancreatic NET while Afinitor, an m-TOR inhibitor, is approved in non-functional neuroendocrine tumors in the pancreas, lung and gastrointestinal tract. These approvals, however, cover only about half of advanced neuroendocrine tumor patients.

The table below shows a summary of the clinical trials that we have completed or are in planning for surufatinib in neuroendocrine cancer patients. Our Phase Ib study in planning for the United States and Europe will also include expansion cohorts to explore surufatinib in patients with biliary tract cancer and sarcoma.

SANET-ep study; Phase III study of surufatinib monotherapy in non-pancreatic neuroendocrine tumors (Status: met primary endpoint; NDA granted priority review; NCT02588170)

In 2015, we initiated the SANET-ep study, which is a Phase III study in China in patients with grade 1 and 2 advanced non-pancreatic neuroendocrine tumors. In this study, patients were randomized at a 2:1 ratio to receive either an oral dose of 300 mg of surufatinib or a placebo once daily on a 28-day treatment cycle. The primary endpoint was progression-free survival, with secondary endpoints including objective response rate, disease control rate, time to response, duration of response, overall survival, safety and tolerability.

A 198-patient interim analysis was conducted on SANET-ep in mid-2019, leading the independent data monitoring committee to determine that it had met the pre-defined primary endpoint of progression-free survival and should be stopped early. The positive results of this trial were highlighted in an oral presentation at the 2019 European Society for Medical Oncology Congress. Median progression-free survival per investigator assessment was 9.2 months for patients treated with surufatinib, as compared to 3.8 months for patients in the placebo group (HR 0.334; 95% CI: 0.223, 0.499; p<0.0001). Efficacy was also supported by a blinded independent image review committee assessment. Surufatinib was well-tolerated in this study and the safety profile is consistent with observations in prior clinical studies. CTC grade 3 or above adverse events in this study with greater than 5% incidence were hypertension (36%), proteinuria (19%) and anemia (7%).

In late 2019, the NMPA granted priority review status to the NDA for surufatinib in non-pancreatic neuroendocrine tumors. We believe the benefit of surufatinib as a monotherapy to patients with non-pancreatic neuroendocrine tumors in China could be significant as compared to the minimal treatment alternatives currently available to them.

SANET-p study; Phase III study of surufatinib monotherapy in pancreatic neuroendocrine tumors (Status: met primary endpoint early; NCT02589821)

In 2016, we initiated the SANET-p study, which is a Phase III study in China in patients with low- or intermediate-grade, advanced pancreatic neuroendocrine tumors. In this study, patients are randomized at a 2:1 ratio to receive either an oral dose of 300 mg of surufatinib or a placebo once daily on a 28-day treatment cycle. The primary endpoint is progression-free survival, with secondary endpoints including objective response rate, disease control rate, time to response, duration of response, overall survival, safety and tolerability.

In early 2020, an interim analysis was conducted on SANET-p, leading the independent data monitoring committee to recommend that the study stop early as the pre-defined primary endpoint of progression-free survival had already been met. Following the success of SANET-p, we now plan to arrange a pre-NDA meeting with the NMPA and will prepare for NDA submission in this indication. The results of this study will be submitted for presentation at a scientific conference in mid-2020.  We believe the benefits of surufatinib as a monotherapy to the approximately 23,400 new patients with pancreatic neuroendocrine tumors in China in 2018 could be significant as compared to the treatment alternatives currently available to them.

88

Phase Ib/IIa study of surufatinib monotherapy in second-line pancreatic neuroendocrine tumors (Status: enrolling; NCT02549937)

We are conducting a multi-center, open-label, Phase Ib clinical study to evaluate the safety, tolerability and pharmacokinetics of surufatinib in U.S. patients, which established the U.S. recommended Phase II dose to be 300 mg, the same as that in China. Preliminary data presented at the 2019 European Society for Medical Oncology Congress showed promising anti-tumor activity with an objective response rate of 13.3% and disease control in 73.3% of the 15 heavily treated pancreatic NET patients. Surufatinib was well tolerated with a safety profile consistent with our China studies.

The FDA granted surufatinib orphan drug designation for the treatment of pancreatic neuroendocrine tumors in November 2019. We are now in regulatory consultations in the United States, Europe and Japan to explore potential registration pathway on the basis of the two positive China Phase III studies (SANET-ep and SANET-p). These consultations are expected to be completed in mid-2020. We target to initiate the global clinical studies required to support NDA submission during 2020.

Biliary Tract Cancer

Biliary tract cancer (also known as cholangiocarcinoma) is a heterogeneous group of rare malignancies arising from the biliary tract epithelia. Gemzar, a type of chemotherapy, is the currently approved first-line therapy for biliary tract cancer patients, with median survival of less than 12 months for patients with unresectable or metastatic disease at diagnosis. As a result, this is a major unmet medical need for patients who have progressed on chemotherapy. There is currently no standard of care for these patients. Surufatinib may offer a new targeted treatment option in this tumor type. The table below shows a summary of the clinical studies that we have underway for surufatinib in biliary tract cancer patients.

Note:    Chemotherapy refractory = resistant to prior chemotherapy treatment; BTC = biliary tract cancer.

Phase II/Ib surufatinib monotherapy in chemotherapy refractory biliary tract cancer – China (Status: enrollment complete; NCT02966821)

In early 2017, we began a Phase Ib/II proof-of-concept study in patients with biliary tract cancer and expect to submit the results of this study for publication during 2020. Preliminary efficacy led us to begin the Phase II/III study discussed below.

Phase IIb/III study of surufatinib monotherapy in second line biliary tract cancer (Status: enrollment complete; NCT03873532)

In early 2019, we initiated a registration-intent Phase IIb/III study comparing surufatinib with capecitabine in patients with unresectable or metastatic biliary tract cancer whose disease progressed on first-line chemotherapy. The primary endpoint is overall survival, and we expect to conduct an interim analysis for futility in 2020.

Surufatinib Combinations with Checkpoint Inhibitors

89

In late 2018, we entered into a global collaboration with Junshi to evaluate the combination of surufatinib with Tuoyi. We have completed a Phase I dose-finding study and will submit results for presentation at an upcoming scientific conference. A Phase II study is enrolling patients in a number of solid tumor indications in China, and a Phase Ib/II study is in planning and expected to be initiated in the U.S. in 2020.

In late 2019, we expanded our global collaboration agreement with Innovent to evaluate the safety and efficacy of Tyvyt in combination with surufatinib.

Exploratory development

We are conducting multiple Phase Ib expansion cohorts in the United States to explore the use of surufatinib in biliary tract cancer and soft tissue sarcoma. In China, we intend to support investigator-initiated studies in multiple solid tumor settings.

4.    HMPL-523 Syk Inhibitor

The result of our over six-year program of discovery and pre-clinical work against Syk is HMPL-523, a highly selective Syk inhibitor with a unique pharmacokinetic profile which provides for higher drug exposure in the tissue than on a whole blood level. We designed HMPL-523 intentionally to have high tissue distribution because it is in the tissue that the B-cell activation associated with rheumatoid arthritis and lupus occurs most often. Furthermore, and somewhat counter intuitively, in hematological cancer the vast majority of cancer cells nest in tissue, with a small proportion of cancer cells releasing and circulating in the blood where they cannot survive for long. We assessed that an effective small molecule Syk inhibitor would need to have superior tissue distribution.

However, many pharmaceutical and biotechnology companies had experienced difficulties in developing a safe and efficacious Syk-targeted drug. For example, the development of the Syk inhibitor Tavalisse for rheumatoid arthritis was one such failed program, although clear efficacy was observed in Phase II and Phase III trials. The main problem was off-target toxicities associated with poor kinase selectivity, such as hypertension and severe diarrhea. Therefore, we believe that kinase selectivity is critical to a successful Syk inhibitor. In addition, Tavalisse was designed as a prodrug in order to improve solubility and oral absorption. A prodrug is medication administered in a pharmacologically inactive form which is converted to an active form once absorbed into circulation. The rate of the metabolism required to release the active form can vary from patient to patient, resulting in large variation in active drug exposures that can impact efficacy. We believe HMPL-523 offers important advantages over intravenous monoclonal antibody immune modulators in rheumatoid arthritis in that small molecule compounds clear the system faster, thereby reducing the risk of infections from sustained suppression of the immune system.

Mechanism of Action

Targeting the B-cell signaling pathway is emerging as a potential means to treat both hematological cancer and immunological diseases. Inhibiting PI3Kδ and BTK, two kinases found along the B-cell signaling pathway, has proven to have clinical efficacy in hematological cancers, with three breakthrough therapies having been recently approved by the FDA. Syk is a key kinase upstream to PI3Kδ and BTK within the B-cell signaling pathway and therefore thought to be an important target for modulating B-cell signaling.

The B-cell Signaling Pathway

Notes:    This graphic is a highly simplified representation of the B-cell signaling pathways, which are each composed of a signaling cascade of the multiple kinases indicated in the graphic. Signaling from the B-cell receptor through the cascade, in simple terms, triggers an immune response, including tumor cell activation, proliferation, survival and migration.

Syk, a target for autoimmune diseases

The central role of Syk in signaling processes is not only in cells of immune responses but also in cell types known to be involved in the expression of tissue pathology in autoimmune, inflammatory and allergic diseases. Therefore, interfering with Syk could represent a possible therapeutic approach for treating these disorders. Indeed, several studies have highlighted Syk as a key player in the pathogenesis of a multitude of diseases, including rheumatoid arthritis, systemic lupus erythematosus and multiple sclerosis.

Syk, a target for oncology

In hematological cancer, we believe Syk is a high potential target. In hematopoietic cells, Syk is recruited to the intracellular membrane by activated membrane receptors like B-cell receptors or another receptor called Fc and then binds to the intracellular domain of the receptors. Syk is activated after being phosphorylated by certain kinases and then further induces downstream intracellular signals including B-cell linker, PI3Kδ, BTK and Phospholipase C-y2 to regulate B-cell proliferation, growth, differentiation, homing, survival, maturation, and immune responses. Syk not only involves the regulation of lymphatic cells but also signal transduction of non-lymphatic cells such as mast cells, macrophages, and basophils, resulting in different immunological functions such as degranulation to release immune active substances, leading to immunological reaction and disease. Therefore, regulating B-cell signal pathways through Syk is expected to be effective for treating lymphoma.

91

The high efficacy and successful approvals of both Imbruvica (developed by AbbVie Inc. and approved for use in China), a BTK inhibitor, and Zydelig (developed by Gilead and not approved currently for use in China), a PI3Kδ inhibitor, are evidence that modulation of the B-cell signaling pathway is critical for the effective treatment of B-cell malignancies. Syk is upstream of both BTK and PI3Kδ, and we believe it could deliver the same outcome as Imbruvica and Zydelig, assuming no unintentional toxicities are derived from Syk inhibition. Entospletinib, a Syk inhibitor developed by Gilead, reported promising Phase II study results in late 2015 with a nodal response rate of 65% observed in chronic lymphocytic leukemia and small lymphocytic lymphoma. Nodal response is defined as a greater than 50% decrease from baseline in the sum of lymph node diameters. Gilead has also reported that entospletinib demonstrated a nodal response rate of 44% in an exploratory clinical study in chronic lymphocytic leukemia patients previously treated with Imbruvica and Zydelig, thereby indicating that Syk inhibition has the potential to overcome resistance to Imbruvica and Zydelig. Takeda reported similarly strong signs of efficacy for their TAK-659 Phase I dose escalation study in lymphoma, which was also published in late 2015.

HMPL-523 Research Background

The threshold of safety for a Syk inhibitor in chronic disease is extremely high, with no room for material toxicity. The failure of Tavalisse in a global Phase III registration study in rheumatoid arthritis provided important insights for us in the area of toxicity. While Tavalisse clearly showed patient benefit in rheumatoid arthritis, a critical proof-of-concept for Syk modulation, it also caused high levels of hypertension which is widely believed to be due to the high levels of off-target KDR inhibition. In addition, Tavalisse has also been shown to strongly inhibit the Ret kinase, and in pre-clinical trials it was demonstrated that inhibition of the Ret kinase was associated with developmental and reproductive toxicities.

The requirement for Syk kinase activity in inflammatory responses was first evaluated with Tavalisse, which was co-developed by AstraZeneca/Rigel Pharmaceuticals, Inc. In 2013, AstraZeneca announced results from pivotal Phase III clinical trials that Tavalisse statistically significantly improved ACR20 (a 20% improvement from baseline based on the study criteria) response rates of patients inadequately responding to conventional disease-modifying anti-rheumatic drugs and a single anti-TNFa (a key pro-inflammatory cytokine involved in rheumatoid arthritis pathogenesis) antagonist at 24 weeks, but failed to demonstrate statistical significance in comparison to placebo at 24 weeks. As a result, AstraZeneca decided not to proceed.

Tavalisse was also in trials for B-cell lymphoma and T-cell lymphoma. It demonstrated some clinical efficacy in diffused large B-cell lymphoma patients with an objective response rate of 22%. Entospletinib has features of high potency and good selectivity toward kinases. However, while the Phase II study discussed above showed that it had significant efficacy in patients with chronic lymphocytic leukemia and small lymphocytic lymphoma, its poor solubility and permeability into intestinal epithelial cells resulted in unsatisfactory oral absorption and a great variation of individual drug exposure. In addition, entospletinib shows some inhibition of the CYP3A4, CYP2D6, and CYP1A2 enzymes involved in the metabolism of certain drugs, and therefore their inhibition could increase the risk of drug-to-drug interaction when used in combined therapy.

HMPL-523 Pre-clinical Evidence

The safety profile of HMPL-523 was evaluated in multiple in vitro and in vivo pre-clinical trials under good laboratory practice guidelines and found to be well tolerated following single dose oral administration. Toxic findings were seen in repeat dose animal safety evaluations in rats and dogs at higher doses and found to be reversible. These findings can be readily monitored in the clinical trials and fully recoverable upon drug withdrawal. The starting dose in humans was suggested to be 5 mg. This dose level is approximately 5% of the human equivalent dose extrapolated from the pre-clinical “no observed adverse event levels,” which is below the 10% threshold recommended by FDA guidelines.

HMPL-523 Clinical Trials

As discussed below, we currently have various clinical trials of HMPL-523 ongoing in Australia, the United States, Europe and China as a monotherapy. The table below shows a summary of the clinical trials that we have underway for HMPL-523.

92

Current Clinical Trials of HMPL-523

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #
HMPL‑523 monotherapy	Indolent non-Hodgkin's lymphoma	Australia	Ib	Enrolling	NCT02503033
HMPL‑523 monotherapy	Multiple subtypes of B cell malignancies	China	Ib	Enrolling	NCT02857998
HMPL‑523 monotherapy	Indolent non-Hodgkin's lymphoma	US/EU	I	Enrolling	NCT03779113
HMPL‑523 monotherapy	Immune thrombocytopenia purpura	China	I	Enrolling	NCT03951623

Phase Ib studies of HMPL-523 in indolent non-Hodgkin’s lymphoma and multiple subtypes of B cell malignancies (Status: enrolling; NCT02503033/NCT02857998)

In early 2016, we initiated a Phase I dose escalation study of HMPL-523 in Australia and have completed seven dose cohorts. A Phase I study in China began in early 2017 and has now completed five dose cohorts. In both Australia and China, we have established both efficacious once daily and twice daily dose regimens. Since early 2018, we have been increasing the number of active clinical sites, now totaling 18, in Australia and China to support a large dose expansion program in a broad range of hematological cancers with over 190 patients now enrolled. We expect these Phase I/Ib data to inform registration study decisions in China in 2020.

Phase I study of HMPL-523 in indolent non-Hodgkin’s lymphoma (Status: enrolling; NCT03779113)

Based on extensive proof-of-concept clinical data in China and Australia, we have now initiated a Phase I/Ib study in the United States and Europe. Patient enrollment is underway.

Phase I/Ib study of HMPL-523 in patients with immune thrombocytopenia (Status: enrolling)

In mid-2019, we initiated a Phase I study of HMPL-523 in patients with immune thrombocytopenia purpura. Immune thrombocytopenia purpura is an autoimmune disorder characterized by low platelet count and an increased bleeding risk. Despite availability of several treatments with differing mechanisms of action, a significant proportion of patients develop resistance to treatment and are prone to relapse. In addition, there is a significant population of patients who have limited sensitivity to currently available agents and are in need of a new approach to treatment.

The study is a randomized, double-blinded, placebo-controlled Phase Ib clinical trial investigating the safety, tolerability, pharmacokinetics and preliminary efficacy of HMPL-523 in adult patients with immune thrombocytopenia purpura. The primary endpoint is the number of patients with any adverse event. The secondary endpoints are maximum plasma concentration, area under the concentration-time curve in a selected time interval, and rate of clinical remission at week eighty. The trial is comprised of a dose escalation stage and a dose expansion stage. Approximately 50 to 60 patients are expected to be enrolled.

5.    HMPL-689 PI3Kδ Inhibitor

HMPL-689 is a novel, highly selective and potent small molecule inhibitor targeting the isoform PI3Kδ, a key component in the B-cell receptor signaling pathway. We have designed HMPL-689 with superior PI3Kδ isoform selectivity, in particular to not inhibit PI3K-g (gamma), offering advantages over Zydelig to minimize the risk of serious infection caused by immune suppression. HMPL-689’s strong potency, particularly at the whole blood level, also allows for reduced daily doses to minimize compound related toxicity, such as the high level of liver toxicity observed with the first-generation PI3Kδ inhibitor Zydelig. HMPL-689’s pharmacokinetic properties have been found to be favorable with good oral absorption, moderate tissue distribution and low clearance in pre-clinical pharmacokinetic studies. We also expect that HMPL-689 will have low risk of drug accumulation and drug-to-drug interaction.

Mechanism of Action

Class I phosphatidylinositide-3-kinases, or PI3Ks, are lipid kinases that, through a series of intermediate processes, control the activation of several important signaling proteins including the serine/threonine kinase AKT. In most cells, AKT is a key PI3K effector that regulates cell proliferation, carbohydrate metabolism, cell motility and apoptosis, and other cellular processes.

93

There are multiple sub-families of PI3K kinases, and PI3Kδ is a lipid kinase that, through a series of intermediate processes, controls the activation of several important signaling proteins, including the serine/threonine kinase AKT. In most cells, AKT is a key PI3Kδ affector that regulates cell proliferation, carbohydrate metabolism, cell motility and apoptosis and other cellular processes. Upon an antigen binding to B-cell receptors, PI3Kδ can be activated through the Lyn and Syk signaling cascade.

Aberrant B-cell function has been observed in multiple immunological diseases and B-cell mediated malignancies. Therefore, PI3Kδ is considered to be a promising target for drugs that aim to prevent or treat hematologic cancer, autoimmunity and transplant organ rejection and other related inflammation diseases.

HMPL-689 Pre-clinical Evidence

Compared to other PI3Kδ inhibitors, HMPL-689 shows higher potency and selectivity.

Our Phase I/Ib study of HMPL-689 in China has successfully established a Phase II dose and has now expanded into multiple sub-categories of indolent non-Hodgkin’s lymphoma. We expect these Phase I/Ib data to inform registration study decisions in China in 2020.

Phase I/Ib study of HMPL-689 in patients with Indolent non-Hodgkin’s lymphoma (Status: enrolling; NCT03786926)

In September 2019, we initiated an international Phase I/Ib study of HMPL-689 in patients with relapsed or refractory lymphoma. The international clinical study, with sites in the United States and Europe, is a multi-center, open-label, two-stage study, including dose escalation and expansion, investigating the effects of HMPL-689 administered orally to patients with relapsed or refractory lymphoma. The primary outcome measures are safety and tolerability. Secondary outcomes include pharmacokinetic measurements and preliminary efficacy such as objective response rate.

6.    HMPL-453 FGFR Inhibitor

Mechanism of Action

FGFR belongs to a subfamily of receptor tyrosine kinases. Four different FGFRs (FGFR1-4) and at least 18 ligand FGFs constitute the FGF/FGFR signaling system. Activation of the FGFR pathway through the phosphorylation of various downstream molecules ultimately leads to increased cell proliferation, migration and survival. FGF/FGFR signaling regulates a wide range of basic biological processes, including tissue development, angiogenesis, and tissue regeneration. Given the inherent complexity and critical roles in physiological processes, dysfunction in the FGF/FGFR signaling leads to a number of developmental disorders and is consistently found to be a driving force in cancer. Deregulation of the FGFR can take many forms, including receptor amplification, activating mutations, gene fusions, and receptor isoform switching, and the molecular alterations are found at relatively low frequencies in most tumors. The incidence of FGFR aberrance in various cancer types is listed in the table below.

Common FGFR Alterations in Certain Tumor Types

	Gene amplification	Gene translocation	Gene mutation
FGFR1	Lung squamous (7-15%)	Lung squamous (n/a)	Gastric (4%)
	H&N squamous (10-17%)	Glioblastoma (n/a)	Pilocytic astrocytoma
	Esophageal squamous (9%)	Myeloproliferative	(5-8%)
	Breast (10-15%)	syndrome (n/a)
		Breast (n/a)
FGFR2	Gastric (5-10%)	Intra-hepatic biliary tract	Endometrial (12-14%)
	Breast (5-10%)	cancer (14%)	Lung squamous (5%)
		Breast (n/a)
FGFR3	Bladder (3%)	Bladder (3-6%)	Bladder (60-80% NMIBC;
	Salivary adenoid cystic (n/a)	Lung squamous (3%)	15-20% MIBC)
	Breast (1%)	Glioblastoma (3-7%)	Cervical (5%)
		Myeloma (15-20%)

Notes:    H&N = head and neck; NMIBC = non-muscle invasive bladder cancer; MIBC = muscle invasive bladder cancer; and n/a = data not available.

HMPL-453 Research Background

We noted a growing body of evidence has demonstrated the oncogenic potential of FGFR aberrations in driving tumor growth, promoting angiogenesis, and conferring resistance mechanisms to oncology therapies. Targeting the FGF/FGFR signaling pathway has therefore attracted attention from biopharmaceutical companies and has become an important exploratory target for new anti-tumor target therapies.

Currently, FGFR monoclonal antibodies, FGF ligand traps and small molecule FGFR tyrosine kinase inhibitors are being evaluated in clinical trials and by regulatory authorities for marketing authorization. These recently approved and late stage molecules provided substantial proof-of-concept with regard to anti-tumor efficacy and pharmacodynamic markers of effective FGFR pathway inhibition. In April 2019, Johnson & Johnson received FDA approval for Balversa in the United States for the treatment of bladder cancer in patients who have susceptible FGFR3 or FGFR2 genetic alterations and experienced disease progression during or after at least one line of chemotherapy. Further studies are either in progress or planning. In 2019, Incyte applied for marketing authorization in the United States and Europe for pemigatinib for the treatment of cholangiocarcinoma, with further studies in progress for additional solid tumor indications. Late stage studies are underway for futibatinib (Taiho, a subsidiary of Otuska), derazantinib (Basilea), and BGJ-398 (QED Therapeutics).

The main FGFR on-target toxicities observed to date in these compounds are all mild and manageable, including hyperphosphatemia, nail and mucosal disorder, and reversible retinal pigmented epithelial detachment. However, there are still many challenges in the development of FGFR-directed therapies. Uncertainties include the screening and stratifying of patients who are most likely to benefit from FGFR targeted therapy. Intra-tumor heterogeneity observed in FGFR amplified cancer may compromise the anti-tumor activity. In addition, the low frequency of specific FGFR molecular aberrance in each cancer type may hinder clinical trial enrollment.

95

HMPL-453 Pre-clinical Evidence

HMPL-453 is a potential best-in-class, highly selective and potent, small molecule that targets FGFR 1/2/3 with an IC₅₀ in the low nanomolar range. Its good selectivity was revealed in the screening against 292 kinases. HMPL-453 exhibited strong anti-tumor activity that correlated with target inhibition in tumor models with abnormal FGFR activation.

HMPL-453 has good pharmacokinetic properties characterized by rapid absorption following oral dosing, good bioavailability, moderate tissue distribution and moderate clearance in all pre-clinical animal species. HMPL-453 was found to have little inhibitory effect on major cytochrome P450 enzymes, indicating low likelihood of drug-to-drug interaction issues.

HMPL-453 Clinical Development

The table below shows a summary of the clinical trials that we have recently completed and underway for HMPL-453.

Clinical Trials of HMPL-453

The table below shows a summary of our clinical studies for HMPL-453.

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #
HMPL-453 monotherapy	Solid tumors	China	I	Enrollment completed	NCT03160833
HMPL-453 monotherapy	Advanced malignant mesothelioma	China	II	Initiating	NCT04290325

Phase I HMPL-453 monotherapy in solid tumors–China (Status: enrollment complete; NCT03160833)

In June 2017, we initiated a Phase I clinical trial of HMPL-453 in China. This Phase I study is a multi-center, single-arm, open-label, two-stage study to evaluate safety, tolerability, pharmacokinetics and preliminary efficacy of HMPL-453 monotherapy in patients with solid tumors harboring FGFR genetic alterations. The dose-escalation stage is currently enrolling patients to further evaluate safety, tolerability and pharmacokinetics as well as preliminary anti-tumor efficacy at the recommended Phase II dose. This stage will enroll primarily cancer patients harboring FGFR dysregulated tumors, including those with advanced bladder cancer, advanced cholangiocarcinoma and other solid tumors. For this second stage, the primary endpoint is objective response rate, with secondary endpoints including duration of response, disease control rate, progression-free survival, overall survival and safety.

Phase I HMPL-453 monotherapy in advanced malignant mesothelioma–China (Status: initiating; NCT04290325

We are initiating a single-arm, multi-center, open-label Phase II study, evaluating the efficacy, safety and pharmacokinetics of HMPL-453 in patients with advanced malignant mesothelioma that failed at least one line of systemic therapy.

7.   HMPL-306

HMPL-306 is a novel small molecule dual-inhibitor of IDH1 and 2 enzymes. IDH1 and IDH2 mutations have been implicated as drivers of certain hematological malignancies, gliomas and solid tumors, particularly among acute myeloid leukemia patients. The NMPA has approved our IND application for HMPL-306, and we expect to begin Phase I development in mid-2020.

8.    Epitinib EGFR Inhibitor

Epitinib (also known as HMPL-813) is a potent and highly selective oral EGFR inhibitor designed to optimize brain penetration. A significant portion of patients with non-small cell lung cancer go on to develop brain metastasis. Patients with brain metastasis suffer from poor prognosis and low quality of life with limited treatment options. EGFR inhibitors have revolutionized the treatment of non-small cell lung cancer with EGFR activating mutations. However, approved EGFR inhibitors such as Iressa and Tarceva cannot penetrate the blood-brain barrier effectively, leaving the majority of patients with brain metastasis without an effective targeted therapy.

Our strategy has been to create targeted therapies in the EGFR area that would go beyond the already approved EGFRm+ non-small cell lung cancer patient population to address certain areas of unmet medical needs that represent significant market opportunities, including: (i) brain metastasis and/or primary brain tumors with EGFRm+, which we seek to address with epitinib; and (ii) tumors with EGFR gene amplification or EGFR overexpressed, which we seek to address with theliatinib as discussed below.

96

Epitinib Pre-clinical Evidence

Pre-clinical trials and orthotopic brain tumor models have shown that epitinib demonstrated brain penetration and efficacy superior to that of current globally marketed EGFRm+ inhibitors such as Iressa and Tarceva. In orthotopic brain tumor models, epitinib demonstrated good brain penetration, efficacy and pharmacokinetic properties as well as a favorable safety profile.

Epitinib Clinical Development

The table below shows a summary of the clinical trials that we have recently completed and underway for epitinib.

Clinical Trials of Epitinib

Treatment	Name, Line, Patient Focus	Sites	Phase	Status/Plan	NCT #
Epitinib monotherapy	Glioblastoma	China	Ib/II	Enrolling	NCT03231501
Epitinib monotherapy	EGFR-mutation NSCLC with brain metastasis	China	Ib	Completed	NCT02590952

Note:    NSCLC = non-small cell lung cancer.

Phase Ib/II epitinib monotherapy in glioblastoma (Status: enrolling; NCT03231501)

Glioblastoma is the most aggressive of the gliomas, which are tumors that arise from glial cells or their precursors within the central nervous system. Glioblastoma is classified as grade IV under the World Health Organization grading of central nervous system tumors, and is the most common brain and central nervous system malignancy, accounting for about half of such tumors according to the Cancer Genome Atlas Research Network. The standard of care for treatment is surgery, followed by radiotherapy and chemotherapy. Median survival is approximately 15 months, and the five-year overall survival rate is 6%. There are currently no target therapies approved for glioblastoma.

Epitinib is a highly differentiated EGFR inhibitor designed for optimal blood-brain barrier penetration. EGFR gene amplification has been identified in about half of glioblastoma patients, according to The Cancer Genome Atlas Research Network, and hence is a potential therapeutic target in glioblastoma.

In March 2018, we initiated a Phase Ib/II proof-of-concept study of epitinib in glioblastoma patients with EGFR gene amplification in China. This Phase Ib/II study will be a multi-center, single-arm, open-label study to evaluate the efficacy and safety of epitinib as a monotherapy in patients with EGFR gene amplified, histologically confirmed glioblastoma.

Phase Ib epitinib monotherapy in non-small cell lung cancer, EGFRm+ with brain metastasis–China (Status: completed; NCT02590952)

In this Phase Ib study, a total of 33 non-small cell lung cancer patients were treated. All responses occurred in EGFR tyrosine kinase inhibitor treatment naïve patients resulting in an objective response rate of 62% and in the 11 EGFR tyrosine kinase inhibitor naïve patients who also had measurable brain metastasis (lesion diameter>10 mm per RECIST 1.1) with a 64% objective response rate. Furthermore, when patients with MET gene amplification were excluded, epitinib’s objective response rate increased to 68% in the EGFR tyrosine kinase inhibitor treatment naïve patients and 70% of those patients who also had measurable brain metastasis. Epitinib was well tolerated with treatment related adverse events in the dose expansion stage CTC grade 3 or above with greater than 10% incidence were elevations in alanine transaminase (19%), elevations in gamma-glutamyltransferase (11%), and aspartate transaminase (11%). In late 2016 we presented this encouraging efficacy data at the World Conference on Lung Cancer.

As the market landscape in EGFRm+ non-small cell lung cancer has become substantially more competitive, we have suspended further development in this population.

97

9.    Theliatinib EGFR Inhibitor

Like epitinib, theliatinib (also known as HMPL-309) is a novel small molecule EGFR inhibitor. Tumors with wild-type EGFR activation, for instance, through gene amplification or protein over-expression, are less sensitive to EGFR tyrosine kinase inhibitors such as Iressa and Tarceva due to sub-optimal binding affinity. Theliatinib was designed with strong affinity to the wild-type EGFR kinase and has demonstrated five to ten times the potency than Tarceva in pre-clinical trials. This holds importance because tumors with wild-type EGFR activation have been found to be less sensitive to current EGFR inhibitors and is notable in certain cancer types such as esophageal cancer, where 15-28% have EGFR gene amplification and 50-70% have EGFR overexpressed. As a result, we believe that theliatinib could potentially be more effective than existing EGFR tyrosine kinase inhibitor products and benefit patients with tumor types with a high incidence of wild-type EGFR activation. We currently retain all rights to theliatinib worldwide.

Theliatinib Pre-clinical Evidence

EGFR is overexpressed in a significant proportion of epithelium-derived carcinomas, which are cancers that begin in a tissue that lines the inner or outer surfaces of the body. Theliatinib inhibits the epidermal growth factor-dependent proliferation of cells at nanomolar concentrations. Of most interest is the strong binding affinity to wild-type EGFR enzyme demonstrated by theliatinib. The data indicated that upon withdrawal of the drug, the EGFR phosphorylation rapidly returns to higher levels for Iressa and Tarceva, while EGFR phosphorylation remained low for theliatinib after drug withdrawal, suggesting theliatinib may demonstrate a sustained target occupancy or “slow-off” characteristic due to strong binding.

Theliatinib Clinical Development

In September 2017, new clinical data were presented at the Annual Meeting of the Chinese Society of Clinical Oncology. Results showed that doses up to 500 mg once daily were determined to be safe and well-tolerated, with no dose-limiting toxicities and no clear maximum tolerated dose. Pharmacokinetic exposure increased with dose, with a 300 mg once daily or more considered to be sufficient to inhibit EGFR phosphorylation. Among the 21 patients that received 120 mg to 500 mg once daily, there were only four treatment-emergent adverse events of grade >3: gastrointestinal bleeding, decreased white blood cell count, anemia or decreased platelet count (1/21 = 5% each). There were no incidences of grade >3 rash or diarrhea. Among seven esophageal cancer patients, five had measurable lesions and could be evaluated for response. All five had stable disease. Of the efficacy evaluable patients in the 120 mg to 500 mg cohorts, 44% (8/18) had stable disease after 12 weeks.

Although we observed efficacy, primarily in the form of stable disease or short duration response, we have decided that it does not warrant continued development of theliatinib monotherapy in esophageal cancer at this time. We now plan to look at alternative uses of theliatinib and could consider the potential for use in combinations with immunotherapy.

Overview of Our Collaborations

Collaborations and joint ventures with corporate partners have provided us with significant funding and access to our partners’ scientific, development, regulatory and commercial capabilities. Our current oncology collaborations focus on savolitinib (collaboration with AstraZeneca) and fruquintinib (collaboration with Eli Lilly). Our collaboration partners fund a significant portion of our research and development costs for drug candidates developed in collaboration with them. In addition, we receive upfront payments upon our entry into these collaboration arrangements and upon the achievement of certain development milestones for the relevant drug candidate. We have received upfront payments, equity contributions and milestone payments totaling approximately $158.5 million mainly from our collaborations with AstraZeneca and Eli Lilly as of December 31, 2019. In return, our collaboration partners are entitled to a significant proportion of any future revenue from our drug candidates developed in collaboration with them, as well as a degree of influence over the clinical development process for such drug candidates.

98

AstraZeneca

In December 2011, we entered into an agreement with AstraZeneca under which we granted to AstraZeneca co-exclusive, worldwide rights to develop, and exclusive worldwide rights to manufacture and commercialize savolitinib for all diagnostic, prophylactic and therapeutic uses. We refer to this agreement as the AstraZeneca Agreement. AstraZeneca paid $20.0 million upon execution of the AstraZeneca Agreement and agreed to pay royalties and additional amounts upon the achievement of development and sales milestones. Under the original terms of the AstraZeneca Agreement, we and AstraZeneca agreed to share the development costs for savolitinib in China, with AstraZeneca being responsible for the development costs for savolitinib in the rest of the world. Based on savolitinib showing early clinical benefit as a highly selective MET inhibitor in a number of cancers, in August 2016 we and AstraZeneca amended our global licensing, co-development, and commercialization agreement for savolitinib whereby we agreed to contribute up to $50 million, spread primarily over three years, to the joint development costs of the global pivotal Phase III study in patients with MET-driven papillary renal cell carcinoma. As of December 31, 2019, we had received $24.9 million in milestone payments in addition to approximately $36.1 million in reimbursements for certain development costs. We may potentially receive future clinical development and first sales milestones payments for clinical development and initial sales of savolitinib, plus significant further milestone payments based on sales. AstraZeneca also reimburses us for certain development costs. Subject to approval of savolitinib in papillary renal cell carcinoma, under the amended AstraZeneca Agreement, AstraZeneca is obligated to pay us increased tiered royalties from 14% to 18% annually on all sales made of any product outside of China, which represents a five percentage point increase over the original terms. After total aggregate sales of savolitinib have reached $5 billion, this royalty will step down over a two year period, to an ongoing royalty rate of 10.5% to 14.5%. AstraZeneca is also obligated to pay us a fixed royalty of 30% on all sales made of any product in China.

Development and collaboration under this agreement are overseen by a joint steering committee that is comprised of three of our senior representatives as well as three senior representatives from AstraZeneca. AstraZeneca is responsible for the development of savolitinib and all regulatory matters related to this agreement in all countries and territories other than China, and we are responsible for the development of savolitinib and all regulatory matters related to this agreement in China.

Subject to earlier termination, the AstraZeneca Agreement will continue in full force and effect on a country-by-country basis as long as any collaboration product is being developed or commercialized. The AstraZeneca Agreement is terminable by either party upon a breach that is uncured, upon the occurrence of bankruptcy or insolvency of either party, or by mutual agreement of the parties. The AstraZeneca Agreement may also be terminated by AstraZeneca for convenience with 180 days’ prior written notice. Termination for cause by us or AstraZeneca or for convenience by AstraZeneca will have the effect of, among other things, terminating the applicable licenses granted by us. Termination for convenience by AstraZeneca will have the effect of obligating AstraZeneca to grant to us all of its rights to regulatory approvals and other rights necessary to commercialize savolitinib. Termination by AstraZeneca for convenience will not have the effect of terminating any license granted by AstraZeneca to us.

Eli Lilly

In October 2013, we entered into an agreement with Eli Lilly whereby we granted Eli Lilly an exclusive license to develop, manufacture and commercialize fruquintinib for all uses in China and Hong Kong. In December 2018, following the commercial launch of fruquintinib in China, we and Eli Lilly amended the terms of the original agreement. We refer to this agreement, including the amendments thereto, as the Eli Lilly Agreement.

Eli Lilly paid a $6.5 million upfront fee following the 2013 execution of the Eli Lilly Agreement, and agreed to pay royalties and additional amounts upon the achievement of development and regulatory approval milestones. As of December 31, 2019, Eli Lilly had paid us $37.2 million in milestone payments in addition to approximately $51.3 million in reimbursements for certain development costs.

We could potentially receive future milestone payments for the achievement of development and regulatory approval milestones in China. Additionally, Eli Lilly is obligated to pay us tiered royalties from 15% to 20% annually on sales made of fruquintinib in China and Hong Kong, the rate to be determined based upon the dollar amount of sales made for all products in that year. Upon the first commercial launch of fruquintinib in China in a new life cycle indication, these tiered royalties will increase to 15% to 29% under the terms of our 2018 amendment.

99

Development, collaboration and manufacture of products under this agreement are overseen by a joint steering committee comprised of equal numbers of representatives from each party. Under the terms of our 2018 amendment, we are now responsible for all development activities and costs for fruquintinib in China in new life cycle indications, and we have the liberty to collaborate with third-parties to explore combination therapies of fruquintinib with various immunotherapy agents.

Once development is complete, Eli Lilly is obligated to use commercially reasonable efforts to commercialize products and bears all the costs and expenses incurred in such commercialization efforts until the achievement of a non-fruquintinib related Eli Lilly commercial action. If this milestone is achieved, we will be given promotion and distribution rights for fruquintinib in provinces that represent 30% (or 40% if certain additional criteria are met) of sales of fruquintinib in China.

We are responsible in consultation with Eli Lilly for the supply of, and have the right to supply, all clinical and commercial supplies for fruquintinib pursuant to an agreed strategy for manufacturing. For the term of the Eli Lilly Agreement, such supplies will be provided by us at a transfer price that accounts for our cost of goods sold.

The Eli Lilly Agreement is terminable by either party for breach that is uncured. The Eli Lilly Agreement is also terminable by Eli Lilly for convenience with 120 days’ prior written notice or if there is a major unexpected safety issue with respect to a product. Termination by either us or Eli Lilly for any reason will have the effect of, among other things, terminating the applicable licenses granted by us, and will obligate Eli Lilly to transfer to us all regulatory materials necessary for us to continue development efforts for fruquintinib.

Nestlé Health Science

In November 2012, we entered into a joint venture agreement with Nestlé Health Science to form Nutrition Science Partners. The objective of Nutrition Science Partners was to develop, manufacture and commercialize HMPL-004/HM004-6599, a drug candidate designed to treat ulcerative colitis and Crohn’s Disease, and to identify, develop, manufacture and commercialize products in gastrointestinal indications. In December 2019, we acquired Nestlé Health Science’s 50% shareholding in Nutrition Science Partners for approximately $8.1 million, representing the cash balance at that time. Nutrition Science Partners currently has no operating activity, and we are evaluating development options for HMPL-004/HM004-6599.

Our Commercial Platform

Our Commercial Platform is a large-scale, high-performance drug marketing and distribution platform covering over 330 cities and towns in China with approximately 3,500 sales personnel as of December 31, 2019. Built over the past 19 years, it has been focused on two main business areas—our strategically important Prescription Drugs business and our Consumer Health business.

Prescription Drugs Business

Our Prescription Drugs division is primarily conducted through the following two joint ventures in which we nominate management and run the day-to-day operations:

Shanghai Hutchison Pharmaceuticals

Shanghai Hutchison Pharmaceuticals primarily engages in the manufacture and sale of prescription drug products originally contributed by our joint venture partner, as well as third-party prescription drugs with a focus on cardiovascular medicine. Shanghai Hutchison Pharmaceuticals’ proprietary products are sold under the “Shang Yao” brand, literally meaning “Shanghai pharmaceuticals,” a trademark that has been used for over 40 years in the pharmaceutical retail market, primarily in Eastern China. In early 2019, Shanghai Hutchison Pharmaceuticals was awarded the 2018 State Scientific and Technological Progress Award – Second Prize, which was presented by President Xi Jinping, Premier Li Keqiang and other state leaders of the PRC at the National Science and Technology Awards Ceremony. This award was one of only two such awards given that year to studies in the botanical drug industry.

As of December 31, 2019, Shanghai Hutchison Pharmaceuticals had a commercial team of about 2,300 medical sales representatives allowing for the promotion and scientific detailing of our products not just in hospitals in provincial capitals and medium-sized cities, but also in the majority of county-level hospitals in China. Shanghai Hutchison Pharmaceuticals’ factory holds 74 drug product manufacturing licenses and is operated by about 540 manufacturing staff.

100

Its key product is She Xiang Bao Xin pills, a vasodilator for the long-term treatment of coronary artery and heart disease and for rapid control and prevention of acute angina pectoris, a form of chest pain. There are over one million deaths due to coronary artery disease per year in China. SXBX pill is the third largest botanical prescription drug in this indication in China, with market share in January to October 2019 of 18.0% (2018: 17.0%) nationally and 51.0% (2018: 48.0%) in Shanghai. She Xiang Bao Xin pills’ sales represented 88% of all Shanghai Hutchison Pharmaceuticals sales in 2019.

She Xiang Bao Xin pills were first approved in 1983 and subsequently enjoyed 23 proprietary commercial protections under the prevailing regulatory system in China. In 2005, Shanghai Hutchison Pharmaceuticals was able to attain “Confidential State Secret Technology” status protection, as certified by China's Ministry of Science and Technology and State Secrecy Bureau, which extended proprietary protection in China until late 2016, and it is in the process of renewing this protection. Shanghai Hutchison Pharmaceuticals holds an invention patent in China covering its formulation, which extends proprietary protection through 2029. SXBX pill is one of less than two dozen proprietary prescription drugs represented on China’s National Essential Medicines List, which means that all Chinese state-owned health care institutions are required to carry it. SXBX pill is fully reimbursed in all of China.

Shanghai Hutchison Pharmaceuticals is also the exclusive co-promoter of Merck Serono’s bisoprolol fumarate tablets, sold under the Concor trademark, in nine provinces, markets that contain about 600 million people. Concor was the number two beta-blocker in China in 2019. Shanghai Hutchison Pharmaceuticals's cardiovascular medical sales team provides detailing for Concor alongside its She Xiang Bao Xin pills on a fee-for-service basis.

Shanghai Hutchison Pharmaceuticals manufactures its products at its 78,000 square meter production facility located in Feng Pu district outside the center of Shanghai.

Hutchison Sinopharm

In 2014, we commenced operating Hutchison Sinopharm, a consolidated joint venture in collaboration with Sinopharm. Based in Shanghai, Hutchison Sinopharm focuses on providing logistics services to, and distributing and marketing prescription drugs in China. As of December 31, 2019, Hutchison Sinopharm had a dedicated team of over 200 commercial staff focused on two key areas of operation—a commercial team that markets over 700 third-party prescription drug products directly to over 360 public and private hospitals in the Shanghai region and through a network of 50 distributors to cover all other provinces in China and a second commercial team that markets our Zhi Ling Tong infant nutrition brand in over 8,000 outlets in China.

Since early 2015, Hutchison Sinopharm had been the exclusive marketing agent for Seroquel tablets in China. In June 2018, AstraZeneca sold and licensed its rights to Seroquel to Luye Pharma Group, Ltd., including its rights in China. The terms of our agreement with AstraZeneca were assigned to Luye Pharma Hong Kong Ltd., or Luye HK. In May 2019, we received a notice from Luye HK purporting to terminate our agreement. We believe that Luye HK has no basis for termination and have commenced legal proceedings to enforce our rights under the agreement.

During 2019, we began building an in-house oncology commercial sales and marketing team at Hutchison Sinopharm to support the launch of certain of our innovative oncology drugs, if approved. This team has grown to approximately 140 commercial sales and marketing staff. As we prepare for the potential launch of surufatinib for the treatment of non-pancreatic neuroendocrine tumors in China, we intend to expand this team to approximately 300 to 350 staff by mid-2020.

Consumer Health Business

Our Consumer Health business is a profitable business, focusing primarily on the manufacture, marketing and distribution of over-the-counter pharmaceutical products. Our Consumer Health business is primarily conducted through our non-consolidated joint venture Hutchison Baiyunshan and also includes the operations of our consolidated joint venture, Hutchison Hain Organic, and our consolidated susbidiaries, Hutchison Healthcare and Hutchison Consumer Products.

Hutchison Baiyunshan

Hutchison Baiyunshan’s “Bai Yun Shan” brand is a market-leading household-name, established over 40 years ago and is known by the majority of Chinese consumers. As of December 31, 2019, Hutchison Baiyunshan held 185 registered drug licenses in China, of which 11 are in active production. In addition to about 1,000 manufacturing staff in Guangdong and Anhui provinces, Hutchison Baiyunshan has a commercial team of about 900 sales staff that covers the national retail pharmacy channel in China.

101

Hutchison Baiyunshan’s key products are two generic over-the-counter therapies:

● Fu Fang Dan Shen tablets—generic over-the-counter drugs for the treatment of chest congestion and angina pectoris to promote blood circulation and relieve pain, which represented approximately 22% of the sales of Hutchison Baiyunshan in 2019; and

● Banlangen granules—for the treatment of viral flu, fever, and respiratory tract infections which represented approximately 30% of the sales of Hutchison Baiyunshan in 2019.

Hutchison Baiyunshan's products are mainly manufactured in-house at facilities in Guangzhou, Guangdong province and Bozhou, Anhui province. Third-party contract manufacturers are also used. Hutchison Baiyunshan also operates cultivation sites through its subsidiaries for growing the herbs used in its over-the-counter products in Heilongjiang province in China. In addition, Hutchison Baiyunshan generates revenue by supplying raw materials produced by its cultivation operations to its collaboration partner, Guangzhou Pharmaceuticals.

Hutchison Baiyunshan sells its products directly to regional distributors across China who on-sell to local distributors, hospitals and clinics, pharmacies and other retailers, and employs its own sales representatives at a local level to market its products and promote over-the-counter sales to retailers.

Hutchison Baiyunshan is in the process of negotiating the return of its land use rights for the approximately 30,000 square meter unused plot of land in Guangzhou, which has been listed for sale as part of the Guangzhou municipal government's urban redevelopment scheme plan since 2016. We expect the sale process to be completed in steps over the next 12 months.

Competition

Innovation Platform Competition

The biotechnology and pharmaceutical industries are highly competitive. While we believe that our highly selective drug candidates, experienced development team and chemistry-focused scientific approach provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies. Any drug candidates that we successfully develop and commercialize will compete with existing drugs and/or new drugs that may become available in the future.

102

We compete in the segments of the pharmaceutical, biotechnology and other related markets that address inhibition of kinases in cancer and immunological diseases. There are other companies working to develop targeted therapies in the field of kinase inhibition for cancer and immunological diseases. These companies include divisions of large pharmaceutical companies and biotechnology companies of various sizes. We also compete with pharmaceutical and biotechnology companies that develop and market monoclonal antibodies as targeted therapies for the treatment of cancer and immunological diseases.

Many of our competitors, either alone or with their strategic partners, have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of drug candidates, obtaining regulatory approvals of products and the commercialization of those products. Accordingly, our competitors may be more successful than we may be in obtaining approval for drugs and achieving widespread market acceptance. Our competitors’ drugs may be more effective, or more effectively marketed and sold, than any drug we may commercialize and may render our drug candidates obsolete or non-competitive before we can recover the expenses of developing and commercializing any of our drug candidates. We anticipate that we will face intense and increasing competition as new drugs enter the market and advanced technologies become available.

Below is a summary of existing therapies and therapies currently under development that may become available in the future which may compete with each of our eight clinical-stage drug candidates.

Savolitinib

While there are currently no approved selective MET inhibitors on the market, there are several MET inhibitors currently undergoing regulatory review, or clinical trials for the treatment of renal cell carcinoma, non-small cell lung cancer and gastric cancer such as Cabometyx (cabozantinib) (VEGFR/MET/Ret inhibitor approved for renal cell carcinoma and in development for non-small cell lung cancer), tepotinib (MET inhibitor in development for non-small cell lung cancer), capmatinib (MET inhibitor in development for non-small cell lung cancer NDA filed in the US and Japan for initial indication), telisotuzumab / telisotuzumab vedotin (MET inhibitor in development for non-small cell lung cancer), MP0250 (vascular endothelial growth factor A/HGF inhibitor in development for non-small cell lung cancer), glesatinib (MET and Axl tyrosine kinase inhibitor in development for non-small cell lung cancer), JNJ-61186372 (VEGFR/MET inhibitor in development for non-small cell lung cancer), AMG 337 (MET kinase inhibitor in development for stomach cancer) and glumetinib (MET kinase inhibitor in Phase I development in China). Xalkori (ALK, ROS1 and MET inhibitor marketed for non-small cell lung cancer) is a multi-kinase inhibitor that less selectively inhibits MET. Merestinib (MST1R, FLT3, AXL, MERTK, TEK, ROS1, DDR1/2, MKNK1/2 and MET inhibitor in development for non-small cell lung cancer) is also a multi-kinase inhibitor.

Fruquintinib

Approved VEGF inhibitors on the market for the treatment of colorectal cancer include Avastin (anti-VEGF monoclonal antibody), Cyramza (anti-VEGFR2 monoclonal antibody), Stivarga (VEGFR/TIE2 inhibitor) and Zaltrap (ziv-aflibercept) (VEGF inhibitor).

Furthermore, small molecules, monoclonal antibodies and radiotherapies are being developed for the treatment of neuroendocrine tumors. Compounds undergoing development for neuroendocrine tumors include Inlyta (axitinib, tyrosine kinase inhibitor), Vargatef (nintedanib, a tyrosine kinase inhibitor), milciclib (tyrosine kinase inhibitor) and Zybrestat (fosbretabulin, a microtubule/tubulin inhibitor being studied for thyroid cancer). Cometriq (an additional brand name for cabozantinib) has been marketed for thyroid cancer and is being studied for neuroendocrine tumors. In addition, Avastin is an anti-VEGF monoclonal antibody being studied for neuroendocrine tumors.

HMPL-523 and HMPL-689

There has been extensive research on oral small-molecule Syk inhibitors due to the major unmet medical need in inflammation and oncology. However, many Syk inhibitors have failed in the development stage due to their off-target toxicity as a result of lower kinase selectivity and possibly poor pharmacokinetic properties. The only small molecule drug candidate targeting Syk specifically has been approved to date is Tavalisse for the treatment of chronic immune thrombocytopenia. GS-9876 is a Syk inhibitor currently in clinical studies for Sjogren’s syndrome and lupus. Syk inhibitors currently in clinical studies for hematological cancers include entospletinib, cerdulatinib and mivavotinib.

Zydelig is a PI3Kδ inhibitor that has been approved for the treatment of relapsed follicular lymphoma, small lymphocytic lymphoma as a monotherapy and for the treatment of chronic lymphatic leukemia in combination with Rituxan. Copiktra (duvelisib, PI3K-δ/γ dual inhibitor) has been approved for relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma and follicular lymphoma as a monotherapy. Aliqopa (copanlisib, pan-PI3K inhibitor) also has been approved for relapsed follicular lymphoma as a monotherapy. In addition, several drug candidates that inhibit PI3Kδ are in clinical development for hematological cancers, including umbralisib, parsaclisib, ACP 319, ME-401 and YY-20394.

In addition, Janus tyrosine kinase, or JAK, inhibitors such as Xeljanz (tofacitinib JAK-3 inhibitor, marketed for rheumatoid arthritis and in development for ulcerative colitis, Crohn’s disease and myelofibrosis), Jakafi (ruxolitinib, JAK-1/2 inhibitor, marketed for myelofibrosis and in development for acute myelogenous leukemia), Olumiant (baricitinib, JAK-1/2 inhibitor marketed for rheumatoid arthritis), filgotinib (JAK-1 inhibitor in development for rheumatoid arthritis, ulcerative colitis and Crohn’s disease) and upadacitinib (JAK-1 inhibitor in development for rheumatoid arthritis, Crohn’s disease, ulcerative colitis, atopic dermatitis, psoriatic arthritis and axial SpA); Bruton’s tyrosine kinase, or BTK, inhibitors such as Imbruvica (ibrutinib), Calquence (acalabrutinib), Brukinsa (zanubrutinib) and tirabrutinib are marketed or in development for various hematological cancers; and TNFα inhibitors marketed for rheumatoid arthritis, such as Enbrel, Remicade, Humira and Cimzia, are also expected to be potential competitors of HMPL-523 or HMPL-689, where indicated for hematological cancers, if approved.

HMPL-453

To date, Balversa is the only approved therapy that specifically targets the FGFR signaling pathway, and pemigatinib is being reviewed for marketing authorization. Late stage studies are underway for futibatinib, derazantinib, and BGJ-398. Several small molecule FGFR tyrosine kinase inhibitors are in early clinical trials for solid tumors, including AZD4547, infigratinib, rogaratinib, BLU-554, Debio 1347, E7090, ASP5878, FGF401, PRN1371 and HH185. Similarly, FGFR specific monoclonal antibodies in development include B-701 and LY3076226.

HMPL-306

Tilbsovo (ivosidenib) is an approved therapy that specifically inhibits IDH1 while Idhifa (enasidenib) is an approved therapy that specifically inhibits IDH2. To date, there are no approved therapies that inhibit both IDH1 and IDH2, which could be advantageous in deferring resistance to therapy. A pan-IDH inhibitor, vorasidenib, is currently in late stage development. Other IDH inhibitors in development include BAY1436032, DS-1001b and FT-2102.

104

Epitinib

Although no EGFR tyrosine kinase inhibitors have been specifically approved for non-small cell lung cancer with brain metastasis or primary brain tumor, many have been approved for the treatment of non-small cell lung cancer with EGFR activating mutations, including Gilotrif (EGFR/HER2 inhibitor), Iressa, Tarceva, Conmana, Tagrisso and Vizimpro. Moreover, Tagrisso, tesevatinib (EGFR/HER2/VEGFR inhibitor) and AZD3759 (EGFR inhibitor) are in development for the treatment of non-small cell lung cancer with brain metastasis while Alecensa (alectinib, an ALK inhibitor) has already been approved.

Theliatinib

Approved EGFR inhibitors on the market include Iressa and Tarceva, although these drugs reach insufficient drug concentrations to suppress wild-type EGFR effectively. In addition, monoclonal antibodies, such as Erbitux, which are approved for the treatment of certain EGFR over-expression tumor types, are less effective for EGFR gene amplified patients. Other small molecule therapies currently being studied for the treatment of esophageal tumors include Gilotrif and Conmana.

Commercial Platform Competition

Our Commercial Platform’s Prescription Drugs business competes in the pharmaceutical industry in China, which is highly competitive and is characterized by a number of established, large pharmaceutical companies, as well as some smaller emerging pharmaceutical companies. Our Prescription Drugs business faces competition from other pharmaceutical companies in China engaged in the development, production, marketing or sales of prescription drugs, in particular cardiovascular drugs. The barrier of entry for the PRC pharmaceutical industry primarily relates to regulatory requirements in connection with the production of pharmaceutical products and new product launches.

The identities of the key competitors with respect to our Prescription Drugs business vary by product, and, in certain cases, different competitors that have greater financial resources than us may elect to focus these resources on developing, importing or in-licensing and marketing products in the PRC that are substitutes for our products and may have broader sales and marketing infrastructure with which to do so.

We believe that we compete primarily on the basis of brand recognition, pricing, sales network, promotion activities, product efficacy, safety and reliability. We believe our continued success will depend on our Prescription Drugs business’s capability to: maintain profitability of its core product, She Xiang Bao Xin pills, successfully market and distribute in-licensed products such as Concor, obtain and maintain regulatory approvals, develop drug candidates with market potential, maintain an efficient operational model, apply technologies to production lines, attract and retain talented personnel, maintain high quality standards, and effectively market and promote the products sold by our Prescription Drugs business. Key competitors for She Xiang Bao Xin pills include Tasly Holding (Compound Danshen Dropping Pill) and Shijiazhuang Yiling Pharmaceutical (Tong Xin Luo Capsule).

Our Commercial Platform’s Consumer Health business competes in a highly fragmented market in Asia, particularly in our primary market in China. We believe that our Consumer Health business competes primarily on the basis of brand recognition, pricing, sales network, promotion activities, product safety and reliability. We believe our continued success will depend on our Consumer Health business’s capability to: maintain profitability of its core products, Fu Fang Dan Shen tablets and Banlangen granules, differentiate its products vis-a-vis those of competitors, successfully market and distribute in-licensed products such as Earth’s Best infant formula, maintain an efficient operational model, attract and retain talented personnel, maintain high quality standards, and effectively market and promote the products sold by our Consumer Health business. In China, Fu Fang Dan Shen tablets and Banlangen granules are generic over-the-counter drugs marketed by several manufacturers. Key competitors include Shanghai LeiYunShang Pharmaceutical, Yunnan Baiyao and Beijing Tongrentang in the Fu Fang Dan Shen market, and include Beijing Tongrentang and Guangzhou Xiangxue Pharmaceutical for the Banlangen market.

105

Patents and Other Intellectual Property

Our commercial success depends in part on our ability to obtain and maintain proprietary or intellectual property protection for our Innovation Platform’s drug candidates, our Commercial Platform’s products and other know-how. Our policy is to seek to protect our proprietary and intellectual property position by, among other methods, filing patent applications in various jurisdictions related to our proprietary technology, inventions and improvements that are important to the development and implementation of our business. We also rely on trade secrets, know-how and continuing technological innovation to develop and maintain our proprietary and intellectual property position.

Patents

We and our joint ventures file patent applications directed to our Innovation Platform’s drug candidates and our Commercial Platform’s products in an effort to establish intellectual property positions with regard to new small molecule compounds and/or extracts of natural herbs, their compositions as well as their medical uses in the treatment of diseases. In relation to our Innovation Platform, we also file patent applications directed to crystalline forms, formulations, processes, key intermediates, and secondary uses as clinical trials for our drug candidates evolve. We file such patent applications in major market jurisdictions, including the United States, Europe, Japan and China as well as Argentina, Australia, Brazil, Canada, Chile, India, Indonesia, Israel, Mexico, Malaysia, New Zealand, Peru, the Philippines, Singapore, South Korea, Ukraine and South Africa. We do not currently in-license any patents except to the extent necessary to ensure our drug candidate fruquintinib has freedom to operate as discussed below.

Our Commercial Platform Patents

Prescription Drugs Patents

As of December 31, 2019, our Prescription Drugs joint venture Shanghai Hutchison Pharmaceuticals had 49 issued patents and 13 pending patent applications in China, including patents for its key prescription products described below.

She Xiang Bao Xin Pills.  As of December 31, 2019, Shanghai Hutchison Pharmaceuticals held an invention patent in China directed to the formulation of the She Xiang Bao Xin pill. Under PRC law, invention patents are granted for new technical innovations with respect to products or processes. Invention patents in China have a maximum term of 20 years. This patent will expire in 2029. The “Confidential State Secret Technology” status protection on the She Xiang Bao Xin pill technology held by Shanghai Hutchison Pharmaceuticals, as certified by China’s Ministry of Science and Technology and State Secrecy Bureau, has expired, and as of December 31, 2019, Shanghai Hutchison Pharmaceuticals was in the process of renewing such protection status, and we believe our status remains unchanged during this process.

108

Danning Tablets.  As of December 31, 2019, Shanghai Hutchison Pharmaceuticals also held an invention patent in China directed to the formulation of the Danning tablet. This patent will expire in 2027.

Consumer Health Patents

Many of the products sold by our Consumer Health Products joint venture Hutchison Baiyunshan, including its Banlangen granules and Fu Fang Dan Shen tablets, are generic, over-the-counter products for which Hutchison Baiyunshan does not hold patents. As of December 31, 2019, Hutchison Baiyunshan had 75 issued patents and 23 pending patents in China, two PCT patents and one in Australia.

Patent Term

The term of a patent depends upon the laws of the country in which it is issued. In most jurisdictions, a patent term is 20 years from the earliest filing date of a non-provisional patent application. In the United States, a patent’s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the USPTO in examining and granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier filed patent. The term of a patent that covers a drug or biological product may also be eligible for patent term extension when FDA approval is granted, provided statutory and regulatory requirements are met. In the future, if and when our drug candidates receive approval by the FDA or other regulatory authorities, we expect to apply for patent term extensions on issued patents covering those drugs, depending upon the length of the clinical trials for each drug and other factors. There can be no assurance that any of our pending patent applications will be issued or that we will benefit from any patent term extension.

As with other pharmaceutical companies, our or our joint ventures’ ability to maintain and solidify our proprietary and intellectual property position for our drug candidates or our or their Commercial Platform products and technologies will depend on our or our joint ventures’ success in obtaining effective patent claims and enforcing those claims if granted. However, our or our joint ventures’ pending patent applications and any patent applications that we or they may in the future file or license from third parties may not result in the issuance of patents. We also cannot predict the breadth of claims that may be allowed or enforced in our or our joint ventures’ patents. Any issued patents that we may receive in the future may be challenged, invalidated or circumvented. For example, we cannot be certain of the priority of filing covered by pending third-party patent applications. If third parties prepare and file patent applications in the United States, China or other markets that also claim technology or therapeutics to which we or our joint ventures have rights, we or our joint ventures may have to participate in interference proceedings, which could result in substantial costs to us, even if the eventual outcome is favorable to us, which is highly unpredictable. In addition, because of the extensive time required for clinical development and regulatory review of a drug candidate we may develop, it is possible that, before any of our drug candidates can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby limiting protection such patent would afford the respective product and any competitive advantage such patent may provide.

Trade Secrets

In addition to patents, we and our joint ventures rely upon unpatented trade secrets and know-how and continuing technological innovation to develop and maintain our or their competitive position. We and our joint ventures seek to protect our proprietary information, in part, by executing confidentiality agreements with our collaborators and scientific advisors, and non-competition, non-solicitation, confidentiality, and invention assignment agreements with our employees and consultants. We and our joint ventures have also executed agreements requiring assignment of inventions with selected scientific advisors and collaborators. The confidentiality agreements we and our joint ventures enter into are designed to protect our or our joint ventures’ proprietary information and the agreements or clauses requiring assignment of inventions to us or our joint ventures, as applicable, are designed to grant us or our joint ventures, as applicable, ownership of technologies that are developed through our or their relationship with the respective counterpart. We cannot guarantee, however, that these agreements will afford us or our joint ventures adequate protection of our or their intellectual property and proprietary information rights.

109

Trademarks and Domain Names

We conduct our business using trademarks with various forms of the “Hutchison,” “Chi-Med” and “China-MediTech” brands, as well as domain names incorporating some or all of these trademarks. In April 2006, we entered into a brand license agreement with Hutchison Whampoa Enterprises Limited, an indirect wholly owned subsidiary of CK Hutchison, pursuant to which we have been granted a non-exclusive, non-transferrable, royalty-free right to use such trademarks, domain names and other intellectual property rights owned by the CK Hutchison group in connection with the operation of our business worldwide. See Item 7.B. “Related Party Transactions—Relationship with CK Hutchison—Intellectual property licensed by the CK Hutchison group” for more details.

In addition, our joint ventures seek trademark protection in China for their Commercial Platform products. As of December 31, 2019, our joint ventures Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan owned a total of 271 trademarks in the aggregate related to products sold by them. For example, the name “Shang Yao” is a registered trademark of Shanghai Hutchison Pharmaceuticals in China for certain uses including pharmaceutical preparations. In addition, our joint venture Hutchison Baiyunshan has been granted a royal-free license to use the registered trademark “Bai Yun Shan” for a term equal to its operational period of the joint venture by Guangzhou Baiyunshan.

Raw Materials and Supplies

Raw materials and supplies are ordered based on our or our joint ventures’ respective sales plans and reasonable order forecasts and are generally available from our or our joint ventures’ own cultivation operations and various third-party suppliers in quantities adequate to meet our needs. We typically order raw materials on short-term contract or purchase order basis and do not enter into long-term dedicated capacity or minimum supply arrangements.

For our Innovation Platform, the active pharmaceutical ingredient, drug product and drug substance used in our drug candidates are supplied to us from third-party vendors. Our ability to successfully develop our drug candidates, and to ultimately supply our commercial drugs in quantities sufficient to meet the market demand, depends in part on our ability to obtain the active pharmaceutical ingredient, drug product and drug substance for these drugs in accordance with regulatory requirements and in sufficient quantities for commercialization and clinical testing.

We generally aim to identify and qualify multiple manufacturers to provide such active pharmaceutical ingredient, drug product and drug substance prior to submission of an NDA to the FDA and/or NMPA. We currently contract with a single supplier to manufacture and supply us with the active pharmaceutical ingredient for fruquintinib for commercial purposes. In addition, we are in the process of engaging a second supplier of such active pharmaceutical ingredient and have already validated its cGMP production processes. We have not yet entered into any purchase or supply agreement with this second supplier so we have not determined the pricing or other commercial terms of this relationship, although based on our discussions with this second supplier and our understanding of the market for this type of ingredient generally, we expect that the pricing of this second supplier will be comparable to our existing supplier. We further manage the risk of price fluctuations and supply disruptions of this active pharmaceutical ingredient by purchasing it in bulk quantities as this ingredient has a relatively long shelf life. Other than the foregoing, we do not currently have arrangements in place for a contingent or second-source supply of the active pharmaceutical ingredients, drug product or drug substance used in our drug candidates in the event any of our current suppliers of such active pharmaceutical ingredient, drug product and drug substance cease their operations for any reason, which may lead to an interruption in our production. However, to date, while we have experienced price fluctuations associated with our raw materials, we have not experienced any material disruptions in the supply of this active pharmaceutical ingredient or the other raw materials we and our joint venture partners use. See Item 3.D. “Risk Factors—Our Commercial Platform’s principal products involve the cultivation or sourcing of key raw materials including botanical products, and any quality control or supply failure or price fluctuations could adversely affect our Commercial Platform’s ability to manufacture our products and/or could materially and adversely affect our operating results.”

Regulation

This section sets forth a summary of the most significant rules and regulations affecting our business activities in China and the United States.

111

Government Regulation of Pharmaceutical Product Development and Approval

PRC Regulation of Pharmaceutical Product Development and Approval

Since China’s entry to the World Trade Organization in 2001, the PRC government has made significant efforts to standardize regulations, develop its pharmaceutical regulatory system and strengthen intellectual property protection.

Regulatory Authorities

In the PRC, the NMPA is the authority that monitors and supervises the administration of pharmaceutical products and medical appliances and equipment as well as cosmetics. The NMPA’s predecessor, the State Drug Administration, or the SDA, was established on August 19, 1998 as an organization under the State Council to assume the responsibilities previously handled by the Ministry of Health of the PRC, or the MOH, the State Pharmaceutical Administration Bureau of the PRC and the State Administration of Traditional Chinese Medicine of the PRC. The SDA was replaced by the State Food and Drug Administration, or the SFDA, in March 2003 and was later reorganized into the China Food and Drug Administration, or the CFDA, in March 2013. On March 17, 2018, the First Session of the Thirteenth National People’s Congress approved the State Council Institutional Reform Proposal, according to which the duties of the CFDA were consolidated into the State Administration for Market Regulation, or the SAMR, and the NMPA was established under the management and supervision of the SAMR.

The primary responsibilities of the NMPA include:

● monitoring and supervising the administration of pharmaceutical products, medical appliances and equipment as well as cosmetics in the PRC;

● formulating administrative rules and policies concerning the supervision and administration of cosmetics and the pharmaceutical industry; evaluating, registering and approving of new drugs, generic drugs, imported drugs and traditional Chinese medicine;

● undertaking the standard, registration, quality and post marketing risk management of pharmaceutical products, medical appliances and equipment as well as cosmetics; and

● examining, evaluating and supervising the safety of pharmaceutical products, medical appliances and equipment as well as cosmetics.

The MOH is an authority at the ministerial level under the State Council and is primarily responsible for national public health. Following the establishment of the SFDA in 2003, the MOH was put in charge of the overall administration of the national health in the PRC excluding the pharmaceutical industry. In March 2008, the State Council placed the SFDA under the management and supervision of the MOH. The MOH performs a variety of tasks in relation to the health industry such as establishing social medical institutes and producing professional codes of ethics for public medical personnel. The MOH is also responsible for overseas affairs, such as dealings with overseas companies and governments. In 2013, the MOH and the National Population and Family Planning Commission were integrated into the National Health and Family Planning Commission of the PRC, or the NHFPC. On March 17, 2018, the First Session of the Thirteenth National People’s Congress approved the State Council Institutional Reform Proposal, according to which the responsibilities of NHFPC and certain other governmental authorities are consolidated into the National Health Commission, or the NHC, and the NHFPC shall no longer be reserved. The responsibilities of the NHC include organizing the formulation of national drug policies, the national essential medicine system and the National Essential Medicines List and drafting the administrative rules for the procurement, distribution and use of national essential medicines.

Healthcare System Reform

The PRC government has promulgated several healthcare reform policies and regulations to reform the healthcare system. On March 17, 2009, the Central Committee of the PRC Communist Party and the State Council jointly issued the Guidelines on Strengthening the Reform of Healthcare System. On March 18, 2009, the State Council issued the Implementation Plan for the Recent Priorities of the Healthcare System Reform (2009-2011). On July 22, 2009, the General Office of the State Council issued the Five Main Tasks of Healthcare System Reform in 2009.

112

Highlights of these healthcare reform policies and regulations include the following:

● The overall objective of the reform is to establish a basic healthcare system to cover both urban and rural residents and provide the Chinese people with safe, effective, convenient and affordable healthcare services. The PRC government aims to extend basic medical insurance coverage to at least 90% of the country’s population by 2011 and increase the amount of subsidies on basic medical insurance for urban residents and rural cooperative medical insurance to RMB120 ($17.54) per person per year by 2010. By 2020, a basic healthcare system covering both urban and rural residents should be established.

● The reforms aim to promote orderly market competition and improve the efficiency and quality of the healthcare system to meet the various medical needs of the Chinese population. From 2009, basic public healthcare services such as preventive healthcare, maternal and child healthcare and health education will be provided to urban and rural residents. In the meantime, the reforms also encourage innovations by pharmaceutical companies to eliminate low-quality and duplicative products.

● The five key tasks of the reform from 2009 to 2011 are as follows: (1) to accelerate the formation of a basic medical insurance system, (2) to establish a national essential drug system, (3) to establish a basic healthcare service system, (4) to promote equal access to basic public healthcare services, and (5) to promote the reform of public hospitals.

Drug Administration Laws and Regulations

The PRC Drug Administration Law as promulgated by the Standing Committee of the National People’s Congress in 1984 and the Implementing Measures of the PRC Drug Administration Law as promulgated by the MOH in 1989 have laid down the legal framework for the establishment of pharmaceutical manufacturing enterprises, pharmaceutical trading enterprises and for the administration of pharmaceutical products including the development and manufacturing of new drugs and medicinal preparations by medical institutions. The PRC Drug Administration Law also regulates the packaging, trademarks and the advertisements of pharmaceutical products in the PRC.

Certain revisions to the PRC Drug Administration Law took effect on December 1, 2001. They were formulated to strengthen the supervision and administration of pharmaceutical products, and to ensure the quality of pharmaceutical products and the safety of pharmaceutical products for human use. The revised PRC Drug Administration Law applies to entities and individuals engaged in the development, production, trade, application, supervision and administration of pharmaceutical products. It regulates and prescribes a framework for the administration of pharmaceutical manufacturers, pharmaceutical trading companies, and medicinal preparations of medical institutions and the development, research, manufacturing, distribution, packaging, pricing and advertisements of pharmaceutical products.

The PRC Drug Administration Law was later amended on December 28, 2013 and April 24, 2015 by the Standing Committee of the National People’s Congress. It provides the basic legal framework for the administration of the production and sale of pharmaceutical products in China and covers the manufacturing, distributing, packaging, pricing and advertising of pharmaceutical products.

On August 26, 2019, the Standing Committee of the National People’s Congress promulgated the amended PRC Drug Administration Law, which took effect on December 1, 2019. The amendment brought a series of changes to the drug supervision and administration system, including but not limited to the clarification of the marketing authorization holder system, pursuant to which the marketing authorization holder shall assume responsibilities for non-clinical studies, clinical trials, manufacturing and marketing, post-marketing studies, monitoring, reporting and handling of adverse reactions of the drug. The amendment also stipulated that the PRC supports the innovation of drugs with clinical value and specific or special effects on human diseases, encourages the development of drugs with new therapeutic mechanisms and promotes the technological advancement of such drugs.

According to the PRC Drug Administration Law, no pharmaceutical products may be produced without a pharmaceutical production license. A manufacturer of pharmaceutical products must obtain a pharmaceutical production license from one of NMPA’s provincial level branches in order to commence production of pharmaceuticals. Prior to granting such license, the relevant government authority will inspect the manufacturer’s production facilities, and decide whether the sanitary conditions, quality assurance system, management structure and equipment within the facilities have met the required standards.

The PRC Drug Administration Implementation Regulations promulgated by the State Council took effect on September 15, 2002 and were later amended on February 6, 2016 and March 2, 2019 to provide detailed implementation regulations for the revised PRC Drug Administration Law.

113

Examination and Approval of New Medicines

On July 10, 2007, the NMPA promulgated the Administrative Measures on the Registration of Pharmaceutical Products, or the Registration Measures, which became effective on October 1, 2007. Under the Registration Measures, new medicines generally refer to those medicines that have not yet been marketed in the PRC. In addition, certain marketed medicines may also be treated as new medicines if the type or application method of such medicines has been changed or new therapeutic functions have been added to such medicines. According to the Registration Measures, the approval of new medicines requires the following steps:

● upon completion of the pre-clinical research of the new medicine, application for registration of the new medicine will be submitted to the drug regulatory authorities at the provincial level for review in formalities. If all the formality requirements are met, the drug regulatory authorities at the provincial level will issue a notice of acceptance and conduct site inspections on the research and original data of the new medicine. The drug regulatory authorities at the provincial level will subsequently issue a preliminary opinion and notify a medical examination institute to conduct a sample examination on the new medicine (if the new medicine is a biological product);

● the drug regulatory authorities at the provincial level will then submit their preliminary opinion, inspection report and application materials to the Drug Review Center of the NMPA and notify the applicant of the progress;

● after receiving the application materials, the Drug Review Center of the NMPA will arrange for pharmaceutical, medical or other professionals to conduct a technical review on the application materials and request for supplemental materials and explanations, if necessary. After completion of the technical review, the Drug Review Center of the NMPA will issue an opinion and submit such opinion to the NMPA, along with the application materials;

● after receiving the technical opinion from the Drug Review Center, the NMPA will assess whether or not to grant the approval for conducting the clinical research on the new medicine;

● after obtaining the NMPA’s approval for conducting the clinical research, the applicant may proceed with the relevant clinical research (which is generally conducted in three phases for a new medicine under the Registration Measures) at institutions with appropriate qualification:

● Phase I refers to the preliminary clinical trial for clinical pharmacology and body safety. It is conducted to observe the human body tolerance for new medicine and pharmacokinetics, so as to provide a basis for determining the prescription plan.

● Phase Ib or II refers to the stage of preliminary evaluation of clinical effectiveness. The purpose is to preliminarily evaluate the clinical effectiveness and safety of the medicine used on patients with targeted indication, as well as to provide a basis for determining the Phase III clinical trial research plan and the volume under the prescription plan.

● Phase III is a clinical trial stage to verify the clinical effectiveness. The purpose is to test and determine the clinical effectiveness and safety of the medicine used on patients with targeted indication, to evaluate the benefits and risks thereof and, eventually, to provide sufficient basis for review of the medicine registration application.

● Phase IV refers the stage of surveillance and research after the new medicines is launched. The purpose is to observe the clinical effectiveness and adverse effects of the medicine over a much larger patient population and longer time period than in Phase I to III clinical trials, and evaluate the benefits and risks when it is administered to general or special patient population in larger prescription volume;

● after completion of the relevant clinical research, the applicant shall submit its clinical research report together with the relevant supporting documents to the drug regulatory authorities at the provincial level and shall provide raw materials of the standard products and research result on relevant standard products to the PRC National Institute for the Control of Pharmaceutical and Biological Products;

114

● the drug regulatory authorities at the provincial level will then review the relevant documents in formalities. If all the formality requirements are met, the drug regulatory authorities at the provincial level will issue a notice of acceptance and within five days of notice and start conducting site inspections. The drug regulatory authorities at the provincial level will issue a preliminary opinion and then collect three samples of the new medicine (if the new medicine is not a biological product) and notify the relevant medicine examination institute to review the medicine standards;

● the drug regulatory authorities at the provincial level will then submit their preliminary opinion, inspection report and application materials to the Drug Review Center of the NMPA and notify the applicant of the progress;

● the medical examination institute will review the medicine standards and report its opinion to the Drug Review Center of the NMPA and send a copy of the opinion to the drug regulatory authorities at the provincial level and the applicant;

● after receiving the application materials, the Drug Review Center of the NMPA will arrange for pharmaceutical, medical or other professionals to conduct a technical review on the application materials and request for supplemental materials and explanations, if necessary. After completion of the technical review and if all the requirements are complied with, the Drug Review Center of the NMPA will report so to the Certification Center of the NMPA and notify the applicant that it may apply to the Certification Center of the NMPA for a site inspection;

● the applicant will apply to the Certification Center of the NMPA for a site inspection within six months after receiving the notice from the Drug Review Center of the NMPA;

● the Certification Center of the NMPA will arrange a site inspection on the process of manufacturing samples within thirty days after the application from the applicant to ensure the feasibility of the manufacturing process. The Certification Center of the NMPA will collect a sample (three samples if the new medicine is a biological product) for the medicine examination institute to examine. The Certification Center of the NMPA will prepare an inspection report within 10 days after the site inspection and submit the report to the Drug Review Center of the NMPA;

● the sample(s) shall be manufactured at a GMP-certified workshop. The medicine examination institute will examine the sample(s) under the reviewed medicine standards and prepare a report after completion the examination and submit the report to the Drug Review Center of the NMPA. A copy of the report will be available to the drug regulatory authorities at the provincial level and the applicant;

● the Drug Review Center of the NMPA will form a comprehensive opinion based on the technical opinion previously received, the report onsite inspection and the result of sample examination and submit the comprehensive opinion and the application materials to the NMPA; and

● if all the regulatory requirements are satisfied, the NMPA will grant a new drug certificate and a pharmaceutical approval number (assuming the applicant has a valid Pharmaceutical Manufacturing Permit and the requisite production conditions for the new medicine have been met).

Any applicant who is not satisfied with the NMPA’s decision to deny an application can appeal within 60 days of its receipt of the NMPA’s decision. If the applicant is dissatisfied with the result of the appeal, it may apply for an administrative review with a special committee consisting of senior officials of the NMPA or file an administrative lawsuit with a people’s court in China.

Pursuant to the Registration Measures, chemical drugs are categorized into six different registration classes. Class I New Chemical Drug is a new chemical drug that has never been marketed in China or abroad, including (1) crude drugs made by synthesis or semi-synthesis and the preparations thereof; (2) new effective monomer extracted from natural substances or by fermentation and the preparations thereof; (3) optical isomer obtained from existing drugs by chiral separation or synthesis and the preparations thereof; (4) drug with fewer components derived from marketed multi-component drugs; (5) new combination products; and (6) a preparation already marketed in China but with a newly added indication not yet approved in any country. Different application materials are required for each registration category.

115

In accordance with the Provisions on the Administration of Special Examination and Approval of Registration of New Drugs promulgated by the NMPA, issued and effective on January 7, 2009, an NDA that meets certain requirements as specified below will be handled with priority in the review and approval process, so-called “green-channel” approval. In addition, the applicant is entitled to provide additional materials during the review period besides those requested by the NMPA, and will have access to enhanced communication channels with the NMPA.

Applicants for the registration of the following new drugs are entitled to request priority treatment in review and approval: (i) active ingredients and their preparations extracted from plants, animals and minerals, and newly discovered medical materials and their preparations that have not been sold in the China market, (ii) chemical drugs and their preparations and biological products that have not been approved for sale at its origin country or abroad, (iii) new drugs with obvious clinical treatment advantages for such diseases as AIDS, therioma, and rare diseases, and (iv) new drugs for diseases that have not been treated effectively. Under category (i) or (ii) above, the applicant for drug registration may apply for special examination and approval when applying for the clinical trial of new drugs; under category (iii) or (iv) above, the applicant may only apply for special examination and approval when applying for manufacturing.

In addition, on December 21, 2017, the NMPA released the Opinions on Priority Review and Approval for Encouraging Drug Innovation, which further clarified that a fast track process for drug registration will be available to:

● the following drugs with distinctive clinical value: (1) innovative drugs not sold within or outside China; (2) innovative drug transferred to be manufactured locally in China; (3) drugs using advanced technology, innovative treatment methods, or having distinctive treatment advantages; (4) traditional Chinese medicines (including ethnic medicines) with clear clinical position in treatment of serious diseases; and (5) new drugs listed in national major science and technology projects or national key research and development plans, and recognized by national clinical medicine research centers which conducted clinical trials of such drugs;

● drugs with distinctive clinical advantages for the prevention and treatment of the following diseases: HIV, phthisis, viral hepatitis, orphan diseases, malignant tumors, children’s diseases, and characteristic and prevalent diseases in elders; and

● drugs which have been concurrently filed with the competent drug approval authorities in the United States or European Union for marketing authorization and passed such authorities’ onsite inspections and are manufactured using the same production line in China.

It also specified that fast track status would be given to clinical trial applications for drugs with patent expiry within three years and manufacturing authorization applications for drugs with patent expiry within one year. Concurrent applications for new drug clinical trials which are already approved in the United States or European Union are also eligible for fast track NMPA approval.

Drug Technology Transfer Regulations

On August 19, 2009, the NMPA promulgated the Administrative Regulations for Technology Transfer Registration of Drugs to standardize the registration process of drug technology transfer, which includes application for, and evaluation, examination, approval and monitoring of, drug technology transfer. Drug technology transfer refers to the transfer of drug production technology by the owner to a drug manufacturer and the application for drug registration by the transferee according to the provisions in the new regulations. Drug technology transfer includes new drug technology transfer and drug production technology transfer.

Conditions for the application for new drug technology transfer

Applications for new drug technology transfer may be submitted prior to the expiration date of the monitoring period of the new drugs with respect to:

● drugs with new drug certificates only; or

● drugs with new drug certificates and drug approval numbers.

116

For drugs with new drug certificates only and not yet in the monitoring period, or drug substances with new drug certificates, applications for new drug technology transfer should be submitted prior to the respective expiration date of the monitoring periods for each drug registration category set forth in the new regulations and after the issue date of the new drug certificates.

Conditions for the application of drug production technology transfer

Applications for drug production technology transfer may be submitted if:

● the transferor holds new drug certificates or both new drug certificates and drug approval numbers, and the monitoring period has expired or there is no monitoring period;

● with respect to drugs without new drug certificates, both the transferor and the transferee are legally qualified drug manufacturing enterprises, one of which holds over 50% of the equity interests in the other, or both of which are majority-owned subsidiaries of the same drug manufacturing enterprise;

● with respect to imported drugs with imported drug licenses, the original applicants for the imported drug registration may transfer these drugs to local drug manufacturing enterprises.

Application for, and examination and approval of, drug technology transfer

Applications for drug technology transfer should be submitted to the provincial food and drug administration. If the transferor and the transferee are located in different provinces, the provincial food and drug administration where the transferor is located should provide examination opinions. The provincial food and drug administration where the transferee is located is responsible for examining application materials for technology transfer and organizing inspections on the production facilities of the transferee. Medical examination institutes are responsible for testing three batches of drug samples.

The Drug Review Center of the NMPA should further review the application materials, provide technical evaluation opinions and form a comprehensive evaluation opinion based on the site inspection reports and the testing results of the samples. The NMPA should determine whether to approve the application according to the comprehensive evaluation opinion of the Drug Review Center of the NMPA. An approval letter of supplementary application and a drug approval number will be issued to qualified applications. An approval letter of clinical trials will be issued when necessary. For rejected applications, a notification letter of the examination opinions will be issued with the reasons for rejection.

Permits and Licenses for Manufacturing and Registration of Drugs

Production Licenses

To manufacture pharmaceutical products in the PRC, a pharmaceutical manufacturing enterprise must first obtain a Pharmaceutical Manufacturing Permit issued by the relevant pharmaceutical administrative authorities at the provincial level where the enterprise is located. Among other things, such a permit must set forth the permit number, the name, legal representative and registered address of the enterprise, the site and scope of production, issuing institution, date of issuance and effective period.

Each Pharmaceutical Manufacturing Permit issued to a pharmaceutical manufacturing enterprise is effective for a period of five years. The enterprise is required to apply for renewal of such permit within six months prior to its expiry and will be subject to reassessment by the issuing authorities in accordance with then prevailing legal and regulatory requirements for the purposes of such renewal.

Business Licenses

In addition to a Pharmaceutical Manufacturing permit, the manufacturing enterprise must also obtain a business license from the administrative bureau of industry and commerce at the local level. The name, legal representative and registered address of the enterprise specified in the business license must be identical to that set forth in the Pharmaceutical Manufacturing Permit.

117

Registration of Pharmaceutical Products

All pharmaceutical products that are produced in the PRC must bear a registered number issued by the NMPA, with the exception of Chinese herbs and Chinese herbal medicines in soluble form. The medicine manufacturing enterprises must obtain the medicine registration number before manufacturing any medicine.

GMP Certificates

The Guidelines on Good Manufacturing Practices, as amended in 1998 and 2010, or the Guidelines, took effect on August 1, 1999 and set the basic standards for the manufacture of pharmaceuticals. These Guidelines cover issues such as the production facilities, the qualification of the personnel at the management level, production plant and facilities, documentation, material packaging and labeling, inspection, production management, sales and return of products and customers’ complaints. On October 23, 2003, the NMPA issued the Notice on the Overall Implementation and Supervision of Accreditation of Good Manufacturing Practice Certificates for Pharmaceuticals, which required all pharmaceutical manufacturers to apply for the GMP certificates by June 30, 2004. Those enterprises that failed to obtain the GMP certificates by December 31, 2004 would have their Pharmaceutical Manufacturing Permit revoked by the drug administrative authorities at the provincial level. On October 24, 2007, the NMPA issued Evaluation Standard on Good Manufacturing Practices which became effective on January 1, 2008. On December 1, 2019, the latest amendment of Drug Administration Law abolished GMP certificates.

Marketing Authorization Holder System

In May 2016, the State Council announced the piloting of the “marketing authorization holder” system in ten provinces in China, where the market authorization/drug license holders are no longer required to be the actual manufacturers. The “marketing authorization holder” system will allow for more flexibilities in contract manufacturing arrangements.

Under the authorization of the Standing Committee of the National People’s Congress, the State Council issued the Pilot Plan for the Drug Marketing Authorization Holder Mechanism on May 26, 2016, providing a detailed pilot plan for the marketing authorization holder system in ten provinces in China. Under the marketing authorization holder system, domestic drug research and development institutions and individuals in the pilot regions are eligible to be holders of drug registrations without having to become drug manufacturers. The marketing authorization holders may engage contract manufacturers for manufacturing, provided that the contract manufacturers are licensed and are also located within the pilot regions. Drugs that qualify for the marketing authorization holder system include: (1) new drugs (including biological products for curative uses of Class I, Class VII and biosimilars under the Administration of Drug Registration) approved after the implementation of the marketing authorization holder system; (2) generic drugs approved as Category 3 or 4 drugs under the Reform Plan for Registration Category of Chemical Medicine issued by the NMPA on March 4, 2016; (3) previously approved generics that have passed equivalence assessments against their original drugs; and (4) previously approved drugs whose licenses were held by drug manufacturers originally located within the pilot regions but have moved out of the pilot regions due to corporate mergers or other reasons.

On August 15, 2017, the NMPA issued the Circular on the Matters Relating to Promotion of the Pilot Program for the Drug Marketing Authorization Holder System, clarifying that the marketing authorization holder shall be responsible for managing the whole manufacturing and marketing chain and the whole life cycle of drugs and shall assume full legal liabilities for the non-clinical drug study, clinical trials, manufacturing, marketing and distribution and adverse drug reaction monitoring. The marketing authorization holder is permitted to entrust several drug manufacturers under the drug quality management system established by the marketing authorization holder. The marketing authorization holder shall submit a report of drug manufacturing, marketing, prescription, techniques, pharmacovigilance, quality control measures and certain other matters to the NMPA within 20 working days after the end of each year.

On December 1, 2019, the latest amendment of Drug Administration Law came into effect, marking the success of the pilot work, and the marketing authorization holder system has become a national system. Pursuant to the latest amendment, the legal representative and the key person-in-charge of a drug marketing authorization holder shall be fully responsible for the quality of drugs.

Administrative Protection and Monitoring Periods for New Drugs

According to the Registration Measures, with a view to protecting public health, the NMPA may provide for administrative monitoring periods of up to five years for new drugs approved to be manufactured, to continually monitor the safety of those new drugs.

118

During the monitoring period of a new drug, the NMPA will not approve any other enterprise’s application to manufacture, change the dosage of or import a similar new drug. The only exception is that the NMPA will continue to handle any application if, prior to the commencement of the monitoring period, the NMPA has already approved the applicant’s clinical trial for a similar new drug. If such application conforms to the relevant provisions, the NMPA may approve such applicant to manufacture or import the similar new drug during the remainder of the monitoring period.

The Administrative Measures Governing the Production Quality of Pharmaceutical Products, or the Administrative Measures for Production, provides detailed guidelines on practices governing the production of pharmaceutical products. A manufacturer’s factory must meet certain criteria in the Administrative Measures for Production, which include: institution and staff qualifications, production premises and facilities, equipment, hygiene conditions, production management, quality controls, product operation, maintenance of sales records and manner of handling customer complaints and adverse reaction reports.

Distribution of Pharmaceutical Products

According to the PRC Drug Administration Law and its implementing regulations and the Measures for the Supervision and Administration of Circulation of Pharmaceuticals, a manufacturer of pharmaceutical products in the PRC can only engage in the trading of the pharmaceutical products that the manufacturer has produced itself. In addition, such manufacturer can only sell its products to:

● wholesalers and distributors holding Pharmaceutical Distribution Permits;

● other holders of Pharmaceutical Manufacturing Permits; or

● medical practitioners holding Medical Practice Permits.

A pharmaceutical manufacturer in the PRC is prohibited from selling its products to end-users, or individuals or entities other than holders of Pharmaceutical Distribution Permits, the Pharmaceutical Manufacturing Permits or the Medical Practice Permits.

The granting of a Pharmaceutical Distribution Permit to wholesalers shall be subject to approval of the provincial level drug regulatory authorities, while the granting of a retailer permit shall be subject to the approval of the drug regulatory authorities above the county level. Unless otherwise expressly approved, no pharmaceutical wholesaler may engage in the retail of pharmaceutical products, and neither may pharmaceutical retailers engage in wholesale.

A pharmaceutical distributor shall satisfy the following requirements:

● personnel with pharmaceutical expertise as qualified according to law;

● business site, facilities, warehousing and sanitary environment compatible to the distributed pharmaceutical products;

● quality management system and personnel compatible to the distributed pharmaceutical products; and

● rules and regulations to ensure the quality of the distributed pharmaceutical products.

Operations of pharmaceutical distributors shall be conducted in accordance with the Pharmaceutical Operation Quality Management Rules.

Pharmaceutical distributors must keep true and complete records of any pharmaceutical products purchased, distributed or sold with the generic name of such products, specification, approval code, term, manufacturer, purchasing or selling party, price and date of purchase or sale. A pharmaceutical distributor must keep such record at least until one year after the expiry date of such products and in any case, such record must be kept for no less than three years. Penalties may be imposed for any violation of record-keeping.

Pharmaceutical distributors can only distribute pharmaceutical products obtained from those with a Pharmaceutical Manufacturing Permit and a Pharmaceutical Distribution Permit.

119

On December 26, 2016, the Medical Reform Office of the State Council, the National Health and Family Planning Commission, the NMPA and other five government authorities promulgated the “Two-Invoice System” Opinions, which became effective on the same date. On April 25, 2017, the General Office of the State Council further promulgated the Notice on Issuing the Key Working Tasks for Deepening the Reform of Medicine and Health System in 2017. According to these rules, a two-invoice system is encouraged to be gradually adopted for drug procurement. The two-invoice system generally requires a drug manufacturer to issue only one invoice to its distributor followed by the distributor issuing a second invoice directly to the end customer hospital. Only one distributor is permitted to distribute drug products between the manufacturer and the hospital. The system also encourages manufacturers to sell drug products directly to hospitals. Public medical institutions are required to adopt the two-invoice system, and its full implementation nationwide is targeted for 2018. Pharmaceutical manufacturers and distributors who fail to implement the two-invoice system may be disqualified from attending future bidding events or providing distribution for hospitals and blacklisted for drug procurement practices. These rules aim to consolidate drug distribution and reduce drug prices. The impact on our company is that Shanghai Hutchison Pharmaceuticals was required to restructure its distribution and logistics network and Hutchison Sinopharm began to shift its prior Seroquel distribution model to a fee-for-service model.

Foreign Investment and “State Secret” Technology

The interpretation of certain PRC laws and regulations governing foreign investment and “state secret” technology is uncertain. Depending on the industry sectors, foreign investments are classified as “encouraged”, “restricted” or “prohibited” under the Guidance Catalogue of Industries for Foreign Investment, or the Catalogue, published by the MOFCOM and the NDRC. Under the Catalogue, “manufacturing of modern Chinese medicines with confidential proprietary formula” has been deemed prohibited for any foreign investment. The technology and know-how of the She Xiang Bao Xin pill is classified as “state secret” technology by China’s Ministry of Science and Technology, or the MOST, and the National Administration for the Protection of State Secrets, or NAPSS.

There are currently no PRC laws or regulations or official interpretations, and therefore there can be no assurance, as to whether the use of “state secret” technology constitutes the “manufacturing of Chinese medicines with confidential proprietary formula” under the Catalogue. However, under the Rules on Confidentiality of Science and Technology promulgated by the State Science and Technology Commission (the predecessor of the MOST and the NAPSS) on January 6, 1995, cooperation with foreign parties or establishing joint ventures with foreign parties in respect of state secret technology is expressly allowed, provided that such cooperation has been duly approved by the relevant science and technology authorities. The establishment of Shanghai Hutchison Pharmaceuticals as a sino-foreign joint venture, including the re-registration of licenses for She Xiang Bao Xin pills in its name, was approved by the local counterpart of the MOFCOM and the Shanghai Drug Administration in 2001. Subsequently, the “Confidential State Secret Technology” status protection for She Xiang Bao Xin pills was also granted in 2005 to Shanghai Hutchison Pharmaceuticals as a sino-foreign joint venture by the MOST and NAPSS. Consequently, we believe Shanghai Hutchison Pharmaceuticals is in compliance with all applicable PRC laws and regulations governing foreign investment and “state secret” technology. Moreover, we believe that our other joint ventures and wholly-foreign owned enterprises in the PRC are also in compliance with all applicable PRC laws and regulations governing foreign investment.

U.S. Regulation of Pharmaceutical Product Development and Approval

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and the Public Health Service Act, or PHSA, and their implementing regulations. The process of obtaining approvals and the subsequent compliance with appropriate federal, state and local rules and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. regulatory requirements at any time during the product development process, approval process or after approval may subject an applicant and/or sponsor to a variety of administrative or judicial sanctions, including refusal by FDA to approve pending applications, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters and other types of enforcement correspondence, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by FDA and the U.S. Department of Justice, or DOJ, or other governmental entities. Drugs are also subject to other federal, state and local statutes and regulations.

120

Our drug candidates must be approved by the FDA through the NDA process before they may be legally marketed in the United States. The process required by the FDA before a drug may be marketed in the United States generally involves the following:

● completion of extensive pre-clinical studies, sometimes referred to as pre-clinical laboratory tests, pre-clinical animal studies and formulation studies all performed in compliance with applicable regulations, including the FDA’s good laboratory practice regulations;

● submission to the FDA of an IND application which must become effective before human clinical trials may begin and must be updated annually;

● IRB approval before each clinical trial may be initiated;

● performance of adequate and well-controlled human clinical trials in accordance with study protocols, the applicable GCPs and other clinical trial-related regulations, to establish the safety and efficacy of the proposed drug product for its proposed indication;

● preparation and submission to the FDA of an NDA;

● a determination by the FDA within 60 days of its receipt of an NDA whether the NDA is acceptable for filing; if the FDA determines that the NDA is not sufficiently complete to permit substantive review, it may request additional information and decline to accept the application for filing until the information is provided;

● in-depth review of the NDA by FDA, which may include review by a scientific advisory committee;

● satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the active pharmaceutical ingredient and finished drug product are produced to assess compliance with the FDA’s current good manufacturing practice requirements, or cGMP;

● potential FDA audit of the pre-clinical and/or clinical trial sites that generated the data in support of the NDA;

● payment of user fees and FDA review and approval of the NDA prior to any commercial marketing or sale of the drug in the United States; and

● compliance with any post-approval requirements, such as REMS and post-approval studies required by FDA.

Pre-clinical Studies

The data required to support an NDA is generated in two distinct development stages: pre-clinical and clinical. For new chemical entities, or NCEs, the pre-clinical development stage generally involves synthesizing the active component, developing the formulation and determining the manufacturing process, evaluating purity and stability, as well as carrying out non-human toxicology, pharmacology and drug metabolism studies in the laboratory, which support subsequent clinical testing. The conduct of the pre-clinical tests must comply with federal regulations, including good laboratory practices. The sponsor must submit the results of the pre-clinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. An IND is a request for authorization from the FDA to administer an investigational drug product to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for human trials. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA raises concerns or questions regarding the proposed clinical trials and places the IND on clinical hold within that 30-day time period. In such a case, the IND sponsor must resolve with the FDA any outstanding concerns or questions before the clinical trial can begin. Some long-term pre-clinical testing, such as animal tests of reproductive adverse events and carcinogenicity, may continue after the IND is submitted. The FDA may also impose clinical holds on a drug candidate at any time before or during clinical trials due to safety concerns or non-compliance. Accordingly, submission of an IND does not guarantee the FDA will allow clinical trials to begin, or that, once begun, issues will not arise that could cause the trial to be suspended or terminated.

121

Clinical Studies

The clinical stage of development involves the administration of the drug product to human subjects or patients under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s control, in accordance with GCPs, which include the requirement that, in general, all research subjects provide their informed consent in writing for their participation in any clinical trial. Clinical trials are conducted under written study protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Further, each clinical trial must be reviewed and approved by each institution at which the clinical trial will be conducted. An IRB is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also reviews and approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. There are also requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries. For example, information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health for public dissemination on their ClinicalTrials.gov website.

Clinical trials are generally conducted in three sequential phases that may overlap or be combined, known as Phase I, Phase II and Phase III clinical trials.

● Phase I: In a standard Phase I clinical trial, the drug is initially introduced into a small number of subjects who are initially exposed to a range of doses of the drug candidate. The primary purpose of these clinical trials is to assess the metabolism, pharmacologic action, appropriate dosing, side effect tolerability and safety of the drug.

● Phase Ib: Although Phase I clinical trials are not intended to treat disease or illness, a Phase Ib trial is conducted in patient populations who have been diagnosed with the disease for which the study drug is intended. The patient population typically demonstrates a biomarker, surrogate, or other clinical outcome that can be assessed to show “proof-of-concept.” In a Phase Ib study, proof-of-concept typically confirms a hypothesis that the current prediction of a biomarker, surrogate or other outcome benefit is compatible with the mechanism of action of the study drug.

● Phase I/II: A Phase I and Phase II trial for the same treatment is combined into a single study protocol. The drug is administered first to determine a maximum tolerable dose, and then additional patients are treated in the Phase II portion of the study to further assess safety and/or efficacy.

● Phase II: The drug is administered to a limited patient population to determine dose tolerance and optimal dosage required to produce the desired benefits. At the same time, safety and further pharmacokinetic and pharmacodynamic information is collected, as well as identification of possible adverse effects and safety risks and preliminary evaluation of efficacy.

● Phase III: The drug is administered to an expanded number of patients, generally at multiple sites that are geographically dispersed, in well-controlled clinical trials to generate enough data to demonstrate the efficacy of the drug for its intended use, its safety profile, and to establish the overall benefit/risk profile of the drug and provide an adequate basis for drug approval and labeling of the drug product. Phase III clinical trials may include comparisons with placebo and/or other comparator treatments. The duration of treatment is often extended to mimic the actual use of a drug during marketing. Generally, two adequate and well-controlled Phase III clinical trials are required by the FDA for approval of an NDA. A pivotal study is a clinical study that adequately meets regulatory agency requirements for the evaluation of a drug candidate’s efficacy and safety such that it can be used to justify the approval of the drug. Generally, pivotal studies are also Phase III studies but may be Phase II studies if the trial design provides a well-controlled and reliable assessment of clinical benefit, particularly in situations where there is an unmet medical need. Post-approval trials, sometimes referred to as Phase 4 clinical trials, are conducted after initial regulatory approval, and they are used to collect additional information from the treatment of patients in the intended therapeutic indication or to meet other regulatory requirements. In certain instances, FDA may mandate the performance of Phase 4 clinical trials.

122

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA, and more frequently if serious adverse events occur. Written IND safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events or any finding from tests in laboratory animals that suggests a significant risk to human subjects. The FDA, the IRB, or the clinical trial sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. The FDA will typically inspect one or more clinical sites to assure compliance with GCPs and the integrity of the clinical data submitted. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group provides authorization for whether or not a trial may move forward at designated check points based on access to certain data from the trial. Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the drug as well as finalize a process for manufacturing the drug in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things, cGMPs impose extensive procedural, substantive and recordkeeping requirements to ensure and preserve the long-term stability and quality of the final drug product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life.

NDA Submission and FDA Review Process

Following trial completion, trial results and data are analyzed to assess safety and efficacy. The results of pre-clinical studies and clinical trials are then submitted to the FDA as part of an NDA, along with proposed labeling for the drug, information about the manufacturing process and facilities that will be used to ensure drug quality, results of analytical testing conducted on the chemistry of the drug, and other relevant information. The NDA is a request for approval to market the drug and must contain adequate evidence of safety and efficacy, which is demonstrated by extensive pre-clinical and clinical testing. The application includes both negative or ambiguous results of pre-clinical and clinical trials as well as positive findings. Data may come from company-sponsored clinical trials intended to test the safety and efficacy of a use of a drug, or from a number of alternative sources, including studies initiated by investigators. To support regulatory approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the investigational drug product to the satisfaction of the FDA. Under federal law, the submission of most NDAs is subject to the payment of an application user fees; a waiver of such fees may be obtained under certain limited circumstances. FDA approval of an NDA must be obtained before a drug may be offered for sale in the United States.

In addition, under the Pediatric Research Equity Act of 2003, or PREA, an NDA or supplement to an NDA must contain data to assess the safety and efficacy of the drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the drug is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers.

Under the Prescription Drug User Fee Act, or PDUFA, as amended, each NDA must be accompanied by an application user fee. The FDA adjusts the PDUFA user fees on an annual basis. According to the FDA’s fee schedule, effective through September 30, 2019, the user fee for an application requiring clinical data, such as an NDA, is $2,588,478. PDUFA also imposes a program fee for prescription human drugs $309,915. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs for products designated as orphan drugs, unless the product also includes a non-orphan indication.

The FDA reviews all NDAs submitted before it accepts them for filing and may request additional information rather than accepting an NDA for filing. The FDA conducts a preliminary review of an NDA within 60 days of receipt and informs the sponsor by the 74th day after FDA’s receipt of the submission to determine whether the application is sufficiently complete to permit substantive review. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. Under the goals and policies agreed to by the FDA under PDUFA, the FDA has 10 months from the filing date in which to complete its initial review of a standard NDA and respond to the applicant, and six months from the filing date for a “priority review” NDA. The FDA does not always meet its PDUFA goal dates for standard and priority review NDAs, and the review process is often significantly extended by FDA requests for additional information or clarification.

123

After the NDA submission is accepted for filing, the FDA reviews the NDA to determine, among other things, whether the proposed drug is safe and effective for its intended use, and whether the drug is being manufactured in accordance with cGMP to assure and preserve the drug’s identity, strength, quality and purity. The FDA may refer applications for drugs or drug candidates that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. The FDA may re-analyze the clinical trial data, which can result in extensive discussions between the FDA and us during the review process.

Before approving an NDA, the FDA will conduct a pre-approval inspection of the manufacturing facilities for the new drug to determine whether they comply with cGMPs. The FDA will not approve the drug unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the drug within required specifications. In addition, before approving an NDA, the FDA may also audit data from clinical trials to ensure compliance with GCP requirements. After the FDA evaluates the application, manufacturing process and manufacturing facilities where the drug product and/or its active pharmaceutical ingredient will be produced, it may issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete and the application is not ready for approval. A Complete Response Letter usually describes all of the specific deficiencies in the NDA identified by the FDA. The Complete Response Letter may require additional clinical data and/or an additional pivotal clinical trial(s), and/or other significant, expensive and time-consuming requirements related to clinical trials, pre-clinical studies or manufacturing. If a Complete Response Letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even if such data and information is submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the same data.

If a drug receives regulatory approval, the approval may be limited to specific diseases and dosages or the indications for use may otherwise be limited. Further, the FDA may require that certain contraindications, warnings or precautions be included in the drug labeling or may condition the approval of the NDA on other changes to the proposed labeling, development of adequate controls and specifications, or a commitment to conduct post-market testing or clinical trials and surveillance to monitor the effects of approved drugs. For example, the FDA may require Phase 4 testing which involves clinical trials designed to further assess a drug’s safety and effectiveness and may require testing and surveillance programs to monitor the safety of approved drugs that have been commercialized. The FDA may also place other conditions on approvals including the requirement for a REMS to ensure that the benefits of a drug or biological product outweigh its risks. If the FDA concludes a REMS is needed, the sponsor of the NDA must submit a proposed REMS. The FDA will not approve the NDA without an approved REMS, if required. A REMS could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of drugs. Drug approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following initial marketing.

Section 505(b)(2) NDAs

NDAs for most new drug products are based on two full clinical studies which must contain substantial evidence of the safety and efficacy of the proposed new product. These applications are submitted under Section 505(b)(1) of the FDCA. The FDA is, however, authorized to approve an alternative type of NDA under Section 505(b)(2) of the FDCA, which authorizes FDA to approve an NDA based on safety and effectiveness data that were not developed by the applicant. Section 505(b)(2) allows the applicant to rely, in part, on the FDA’s previous findings of safety and efficacy for a similar product, or published literature. Specifically, Section 505(b)(2) applies to NDAs for a drug for which the investigations relied upon to show that the drug is safe and effective for the intended use “were not conducted by or for the applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom the investigations were conducted.”

Section 505(b)(2) authorizes NDAs filed under Section 505(b)(2) may provide an alternate and potentially more expeditious pathway to FDA approval for new or improved formulations or new uses of previously approved products. If the 505(b)(2) applicant can establish that reliance on the FDA’s previous approval is scientifically appropriate, the applicant may eliminate the need to conduct certain pre-clinical or clinical studies of the new product. The FDA may also require companies to perform additional studies or measurements to support the change from the approved product. The FDA may then approve the new drug candidate for all or some of the label indications for which the referenced product has been approved, as well as for any new indication sought by the Section 505(b)(2) applicant.

124

Abbreviated New Drug Applications for Generic Drugs

In 1984, with passage of the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Act, Congress authorized the FDA to approve generic drugs that are the same as drugs previously approved by the FDA under the NDA provisions of the statute. To obtain approval of a generic drug, an applicant must submit an abbreviated new drug application, or ANDA, to the agency. In support of such applications, a generic manufacturer may rely on the pre-clinical and clinical testing previously conducted for a drug product previously approved under an NDA, known as the reference listed drug, or RLD.

Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to the active ingredients, the route of administration, the dosage form, and the strength of the drug. At the same time, the FDA must also determine that the generic drug is “bioequivalent” to the innovator drug. Under the statute, a generic drug is bioequivalent to a RLD if “the rate and extent of absorption of the drug do not show a significant difference from the rate and extent of absorption of the listed drug.” The Generic Drug User Fee Act (GDUFA), as reauthorized, sets forth performance goals for FDA to review standard ANDA’s within 10 months of their submission, and priority ANDA’s within 8 months of their submission if they satisfy certain requirements.

Upon approval of an ANDA, the FDA indicates that the generic product is “therapeutically equivalent” to the RLD and it assigns a therapeutic equivalence rating to the approved generic drug in its publication “Approved Drug Products with Therapeutic Equivalence Evaluations,” also referred to as the “Orange Book.” Physicians and pharmacists consider an “AB” therapeutic equivalence rating to mean that a generic drug is fully substitutable for the RLD. In addition, by operation of certain state laws and numerous health insurance programs, FDA’s designation of an “AB” rating often results in substitution of the generic drug without the knowledge or consent of either the prescribing physician or patient.

Special FDA Expedited Review and Approval Programs

The FDA has various programs, including Fast Track Designation, accelerated approval, priority review and Breakthrough Therapy Designation, that are intended to expedite or simplify the process for the development and FDA review of drugs that are intended for the treatment of serious or life threatening diseases or conditions and demonstrate the potential to address unmet medical needs. The purpose of these programs is to provide important new drugs to patients earlier than under standard FDA review procedures. While these pathways can reduce the time it takes for the FDA to review an NDA, they do not guarantee that a product will receive FDA approval. In addition, the Right to Try Act of 2018 established a new regulatory pathway to increase access to unapproved, investigational treatments for patients diagnosed with life-threatening diseases or conditions who have exhausted approved treatment options and who are unable to participate in a clinical trial.

Fast Track Designation

To be eligible for a Fast Track Designation, the FDA must determine, based on the request of a sponsor, that a drug is intended to treat a serious or life threatening disease or condition for which there is no effective treatment and demonstrates the potential to address an unmet medical need for the disease or condition. Under the fast track program, the sponsor of a drug candidate may request FDA to designate the product for a specific indication as a fast track product concurrent with or after the filing of the IND for the drug candidate. The FDA must make a fast track designation determination within 60 days after receipt of the sponsor’s request.

In addition to other benefits, such as the ability to use surrogate endpoints and have greater interactions with FDA, FDA may initiate review of sections of a fast track product’s NDA before the application is complete. This rolling review is available if the applicant provides, and FDA approves, a schedule for the submission of the remaining information and the applicant pays applicable user fees. However, FDA’s time period goal for reviewing a fast track application does not begin until the last section of the NDA is submitted. A fast track drug also may be eligible for accelerated approval and priority review. In addition, the fast track designation may be withdrawn by FDA if FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

125

Priority Review

The FDA may give a priority review designation to drugs that offer major advances in treatment, or provide a treatment where no adequate therapy exists. A priority review means that the goal for the FDA to review an application is six months, rather than the standard review of 10 months under current PDUFA guidelines. These 6- and 10-month review periods are measured from the “filing” date rather than the receipt date for NDAs for new molecular entities, which typically adds approximately two months to the timeline for review and decision from the date of submission. Most products that are eligible for Fast Track Designation are also likely to be considered appropriate to receive a priority review.

Breakthrough Therapy Designation

Under the provisions of the new Food and Drug Administration Safety and Innovation Act, or FDASIA, enacted by Congress in 2012, a sponsor can request designation of a drug candidate as a “breakthrough therapy,” typically by the end of the drug’s Phase II trials. A breakthrough therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Drugs designated as breakthrough therapies are also eligible for accelerated approval. For breakthrough therapies, the FDA may take certain actions, such as intensive and early guidance on the drug development program, that are intended to expedite the development and review of an application for approval.

Accelerated Approval

FDASIA also codified and expanded on FDA’s accelerated approval regulations, under which FDA may approve a drug for a serious or life-threatening illness that provides meaningful therapeutic benefit over existing treatments based on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on an intermediate clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. A surrogate endpoint is a marker that does not itself measure clinical benefit but is believed to predict clinical benefit. This determination takes into account the severity, rarity or prevalence of the disease or condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require a sponsor of a drug receiving accelerated approval to perform Phase 4 or post-marketing studies to verify and describe the predicted effect on irreversible morbidity or mortality or other clinical endpoint, and the drug may be subject to accelerated withdrawal procedures. All promotional materials for drug candidates approved under accelerated regulations are subject to prior review by the FDA.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. Furthermore, Fast Track Designation, priority review, accelerated approval and Breakthrough Therapy Designation, do not change the standards for approval and may not ultimately expedite the development or approval process.

Pediatric Trials

Under PREA, an NDA or supplement thereto must contain data that are adequate to assess the safety and effectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. With the enactment of FDASIA, a sponsor who is planning to submit a marketing application for a drug that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration must also submit an initial Pediatric Study Plan, or PSP, within sixty days of an end-of-Phase II meeting or as may be agreed between the sponsor and FDA. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. FDA and the sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from pre-clinical studies, early phase clinical trials, and/or other clinical development programs. The law requires the FDA to send a non-compliance letters to sponsors who do not submit their pediatric assessments as required.

126

Under the Best Pharmaceuticals for Children Act, or BPCA, certain therapeutic candidates may obtain an additional six months of exclusivity if the sponsor submits information requested by the FDA, relating to the use of the active moiety of the product candidate in children. Although the FDA may issue a written request for studies on either approved or unapproved indications, it may only do so where it determines that information relating to that use of a product candidate in a pediatric population, or part of the pediatric population, may produce health benefits in that population.

FDASIA permanently reauthorized PREA and BPCA, modifying some of the requirements under these laws, and established priority review vouchers for rare pediatric diseases.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, FDA may designate a drug product as an “orphan drug” if it is intended to treat a rare disease or condition (generally meaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a drug product available in the United States for treatment of the disease or condition will be recovered from sales of the product). A company must request orphan product designation before submitting an NDA. If the request is granted, FDA will disclose the identity of the therapeutic agent and its potential use. Orphan product designation does not convey any advantage in or shorten the duration of the regulatory review and approval process, but the product will be entitled to orphan product exclusivity, meaning that FDA may not approve any other applications for the same product for the same indication for seven years, except in certain limited circumstances. Competitors may receive approval of different products for the indication for which the orphan product has exclusivity and may obtain approval for the same product but for a different indication. If a drug or drug product designated as an orphan product ultimately receives regulatory approval for an indication broader than what was designated in its orphan product application, it may not be entitled to exclusivity. The 21st Century Cures Act, which became law in December 2016, expanded the types of studies that qualify for orphan drug grants. Orphan drug designation also may qualify an applicant for federal tax credits relating to research and development costs.

Post-Marketing Requirements

Following approval of a new drug, a pharmaceutical company and the approved drug are subject to continuing regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting to the applicable regulatory authorities of adverse experiences with the drug, providing the regulatory authorities with updated safety and efficacy information, drug sampling and distribution requirements, and complying with applicable promotion and advertising requirements.

Prescription drug advertising is subject to federal, state and foreign regulations. In the United States, the FDA regulates prescription drug promotion, including standards for direct-to-consumer advertising, restrictions on promoting drugs for uses or in patient populations that are not described in the drug’s approved labeling (known as “off-label use”), limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may legally prescribe drugs for off-label uses, manufacturers may not market or promote such off-label uses. Prescription drug promotional materials must be submitted to the FDA in conjunction with their first use. Modifications or enhancements to the drug or its labeling or changes of the site of manufacture are often subject to the approval of the FDA and other regulators, which may or may not be received or may result in a lengthy review process. Any distribution of prescription drugs and pharmaceutical samples also must comply with the U.S. Prescription Drug Marketing Act a part of the FDCA.

127

In the United States, once a drug is approved, its manufacture is subject to comprehensive and continuing regulation by the FDA. The FDA regulations require that drugs be manufactured in specific approved facilities and in accordance with cGMP. Applicants may also rely on third parties for the production of clinical and commercial quantities of drugs, and these third parties must operate in accordance with cGMP regulations. cGMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. These regulations also impose certain organizational, procedural and documentation requirements with respect to manufacturing and quality assurance activities. NDA holders using third-party contract manufacturers, laboratories or packagers are responsible for the selection and monitoring of qualified firms, and, in certain circumstances, qualified suppliers to these firms. These firms and, where applicable, their suppliers are subject to inspections by the FDA at any time, and the discovery of violative conditions, including failure to conform to cGMP, could result in enforcement actions that interrupt the operation of any such facilities or the ability to distribute drugs manufactured, processed or tested by them. Discovery of problems with a drug after approval may result in restrictions on a drug, manufacturer, or holder of an approved NDA, including, among other things, recall or withdrawal of the drug from the market, and may require substantial resources to correct.

The FDA also may require post-approval testing, sometimes referred to as Phase 4 testing, risk minimization action plans and post-marketing surveillance to monitor the effects of an approved drug or place conditions on an approval that could restrict the distribution or use of the drug. Discovery of previously unknown problems with a drug or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a drug’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our drugs under development.

Other U.S. Regulatory Matters

Manufacturing, sales, promotion and other activities following drug approval are also subject to regulation by numerous regulatory authorities in addition to the FDA, including, in the United States, the Centers for Medicare & Medicaid Services, other divisions of the Department of Health and Human Services, the Drug Enforcement Administration for controlled substances, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency and state and local governments. In the United States, sales, marketing and scientific/educational programs must also comply with state and federal fraud and abuse laws. Pricing and rebate programs must comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more recent requirements in the Affordable Care Act. If drugs are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. The handling of any controlled substances must comply with the U.S. Controlled Substances Act and Controlled Substances Import and Export Act. Drugs must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, promotion and other activities are also potentially subject to federal and state consumer protection and unfair competition laws.

The distribution of pharmaceutical drugs is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical drugs.

The failure to comply with regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result in criminal prosecution, fines or other penalties, injunctions, recall or seizure of drugs, total or partial suspension of production, denial or withdrawal of product approvals, or refusal to allow a firm to enter into supply contracts, including government contracts. In addition, even if a firm complies with FDA and other requirements, new information regarding the safety or efficacy of a product could lead the FDA to modify or withdraw product approval. Prohibitions or restrictions on sales or withdrawal of future products marketed by us could materially affect our business in an adverse way.

128

Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

U.S. Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of the FDA approval of our drug candidates, some of our U.S. patents may be eligible for limited patent term extension under the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA plus the time between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In 2018, the FDA advanced policies aimed at promoting drug competition and patient access to generic drugs, such as issuing guidance about making complex generic drugs and the circumstances in which approval of a generic product application may be delayed.

Marketing exclusivity provisions under the FDCA can also delay the submission or the approval of certain marketing applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to obtain approval of an NDA for a NCE. A drug is a NCE if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an ANDA, or a 505(b)(2) NDA submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same indication as the original innovator drug or for another indication, where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder. Specifically, the applicant must certify with respect to each relevant patent that: the required patent information has not been filed; the listed patent has expired; the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration, or the listed patent is invalid, unenforceable or will not be infringed by the new product. A certification that the new product will not infringe the already approved product’s listed patents or that such patents are invalid or unenforceable is called a Paragraph IV certification. If the applicant does not challenge the listed patents or indicate that it is not seeking approval of a patented method of use, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days after the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months after the receipt of the Paragraph IV notice, expiration of the patent, or a decision in the infringement case that is favorable to the ANDA applicant. To the extent that the Section 505(b)(2) applicant relies on prior FDA findings of safety and efficacy, the applicant is required to certify to the FDA concerning any patents listed for the previously approved product in the Orange Book to the same extent that an ANDA applicant would.

The FDCA also provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the active agent for the original indication or condition of use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the pre-clinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness. Orphan drug exclusivity, as described above, may offer a seven-year period of marketing exclusivity, except in certain circumstances. Pediatric exclusivity is another type of regulatory market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric trial in accordance with an FDA-issued “Written Request” for such a trial.

Rest of the World Regulation of Pharmaceutical Product Development and Approval

For other countries outside of China and the United States, such as countries in Europe, Latin America or other parts of Asia, the requirements governing the conduct of clinical trials, drug licensing, pricing and reimbursement vary from country to country. In all cases the clinical trials must be conducted in accordance with GCP requirements and the applicable regulatory requirements and ethical principles.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Coverage and Reimbursement

PRC Coverage and Reimbursement

Historically, most of Chinese healthcare costs have been borne by patients out-of-pocket, which has limited the growth of more expensive pharmaceutical products. However, in recent years the number of people covered by government and private insurance has increased. According to the PRC National Bureau of Statistics, as of December 31, 2019, approximately 1.4 billion employees and residents in China were enrolled in the national medical insurance program, representing an increase of 9.8 million from December 31, 2018. The PRC government has announced a plan to give every person in China access to basic healthcare by year 2020.

Reimbursement under the National Medical Insurance Program

The National Medical Insurance Program was adopted pursuant to the Decision of the State Council on the Establishment of the Urban Employee Basic Medical Insurance Program issued by the State Council on December 14, 1998, under which all employers in urban cities are required to enroll their employees in the basic medical insurance program and the insurance premium is jointly contributed by the employers and employees. The State Council promulgated Guiding Opinions of the State Council about the Pilot Urban Resident Basic Medical Insurance on July 10, 2007, under which urban residents of the pilot district, rather than urban employees, may voluntarily join Urban Resident Basic Medical Insurance. The State Council expects the Pilot Urban Resident Basic Medical Insurance to cover the whole nation by 2010.

Participants of the National Medical Insurance Program and their employers, if any, are required to contribute to the payment of insurance premiums on a monthly basis. Program participants are eligible for full or partial reimbursement of the cost of medicines included in the National Reimbursement Drug List. The Notice Regarding the Tentative Measures for the Administration of the Scope of Medical Insurance Coverage for Pharmaceutical Products for Urban Employees, jointly issued by several authorities including the Ministry of Labor and Social Security and the MOF, among others, on May 12, 1999, provides that a pharmaceutical product listed in the National Reimbursement Drug List must be clinically needed, safe, effective, reasonably priced, easy to use, available in sufficient quantity, and must meet the following requirements:

● it is set forth in the Pharmacopoeia of the PRC;

● it meets the standards promulgated by the NMPA; and

● if imported, it is approved by the NMPA for import.

Factors that affect the inclusion of a pharmaceutical product in the National Reimbursement Drug List include whether the product is consumed in large volumes and commonly prescribed for clinical use in the PRC and whether it is considered to be important in meeting the basic healthcare needs of the general public.

The PRC Ministry of Labor and Social Security, together with other government authorities, has the power to determine the medicines included in the National Reimbursement Drug List, which is divided into two parts, Part A and Part B. Provincial governments are required to include all Part A medicines listed on the National Reimbursement Drug List in their provincial National Reimbursement Drug List, but have the discretion to adjust upwards or downwards by no more than 15% from the number of Part B medicines listed in the National Reimbursement Drug List. As a result, the contents of Part B of the provincial National Reimbursement Drug List may differ from region to region in the PRC.

130

Patients purchasing medicines included in Part A of the National Reimbursement Drug List are entitled to reimbursement of the entire amount of the purchase price. Patients purchasing medicines included in Part B of the National Reimbursement Drug List are required to pay a certain percentage of the purchase price and obtain reimbursement for the remainder of the purchase price. The percentage of reimbursement for Part B medicines differs from region to region in the PRC.

The total amount of reimbursement for the cost of medicines, in addition to other medical expenses, for an individual participant under the National Medical Insurance Program in a calendar year is capped at the amounts in such participant’s individual account under such program. The amount in a participant’s account varies, depending on the amount of contributions from the participant and his or her employer.

National Essential Medicines List

On August 18, 2009, MOH and eight other ministries and commissions in the PRC issued the Provisional Measures on the Administration of the National Essential Medicines List, which was later amended in 2015, and the Guidelines on the Implementation of the Establishment of the National Essential Medicines System, which aim to promote essential medicines sold to consumers at fair prices in the PRC and ensure that the general public in the PRC has equal access to the drugs contained in the National Essential Medicines List. MOH promulgated the National Essential Medicines List (Catalog for the Basic Healthcare Institutions) on August 18, 2009, and promulgated the revised National Essential Medicines List on March 13, 2013 and September 30, 2018. According to these regulations, basic healthcare institutions funded by government, which primarily include county-level hospitals, county-level Chinese medicine hospitals, rural clinics and community clinics, shall store up and use drugs listed in the National Essential Medicines List. The drugs listed in National Essential Medicines List shall be purchased by centralized tender process and shall be subject to the price control by the NDRC. Remedial drugs in the National Essential Medicines List are all listed in the National Reimbursement Drug List and the entire amount of the purchase price of such drugs is entitled to reimbursement.

Price Controls

According to the Pharmaceutical Administration Law and the Regulations of Implementation of the Law of the People’s Republic of China on the Administration of Pharmaceuticals, pharmaceutical products are subject to fixed or directive pricing system or to be adjusted by the market. Those pharmaceutical products included in the National Reimbursement Drug List and the National Essential Medicines List and those drugs the production or trading of which are deemed to constitute monopolies, are subject to price controls by the PRC government in the form of fixed retail prices or maximum retail prices. Manufacturers and distributors cannot set the actual retail price for any given price controlled product above the maximum retail price or deviate from the fixed retail price set by the government. The retail prices of pharmaceutical products that are subject to price controls are administered by the NDRC and provincial and regional price control authorities. From time to time, the NDRC publishes and updates a list of pharmaceutical products that are subject to price controls. According to the Notice Regarding Measures on Government Pricing of Pharmaceutical Products issued by NDRC effective on December 25, 2000, maximum retail prices for pharmaceutical products shall be determined based on a variety of factors, including production costs, the profit margins that the relevant government authorities deem reasonable, the product’s type, and quality, as well as the prices of substitute pharmaceutical products.

Further, pursuant to the Notice Regarding Further Improvement of the Order of Market Price of Pharmaceutical Products and Medical Services jointly promulgated by the NDRC, the State Council Legislative Affairs Office and the State Council Office for Rectifying, the MOH, the NMPA, the MOFCOM, the MOF and Ministry of Labor and Social Security on May 19, 2006, the PRC government exercises price control over pharmaceutical products included in the National Reimbursement Drug List and made an overall adjustment of their prices by reducing the retail price of certain overpriced pharmaceutical products and increasing the retail price of certain underpriced pharmaceutical products in demand for clinical use but that have not been produced in large quantities by manufacturers due to their low retail price level. In particular, the retail price charged by hospitals at the county level or above may not exceed 115% of the procurement cost of the relevant pharmaceutical products or 125% for Chinese herbal pieces.

On February 9, 2015, the General Office of the State Council issued the Guiding Opinion on Enhancing Consolidated Procurement of Pharmaceutical Products by Public Hospitals, or the Opinion. The Opinion encourages public hospitals to consolidate their demands and to play a more active role in the procurement of pharmaceutical products. Hospitals are encouraged to directly settle the prices of pharmaceutical products with manufacturers. Consolidated procurement of pharmaceutical products should facilitate hospital reform, reduce patient costs, prevent corrupt conducts, promote fair competition and induce the healthy growth of the pharmaceutical industry. According to the Opinion, provincial tendering processes will continue to be used for the pricing of essential drugs and generic drugs with significant demands, and transparent multi-party price negotiation will be used for some patented drugs and exclusive drugs.

131

On April 26, 2014, the NDRC issued the Notice on Issues concerning Improving the Price Control of Low Price Drugs, or the Low Price Drugs Notice, together with the LPDL. According to the Low Price Drugs Notice, for drugs with relatively low average daily costs within the current government-guided pricing scope (low price drugs), the maximum retail prices set by the government were cancelled. Within the standards of average daily costs, the specific purchase and sale prices are fixed by the producers and operators based on the drug production costs, market supply and demand and market competition. The standards of average daily costs of low price drugs are determined by the NDRC in consideration of the drug production costs, market supply and demand and other factors and based on the current maximum retail prices set by the government (or the national average bid-winning retail prices where the government does not set the maximum retail prices) and the average daily dose calculated according to the package insert. Under the Low Price Drugs Notice, the current standards for the daily cost of low price chemical pharmaceuticals and of low price traditional Chinese medicine pharmaceuticals are less than RMB3.0 ($0.43) per day and RMB5.0 ($0.71) per day respectively.

On May 4, 2015, the NDRC, the National Health and Family Planning Commission, the NMPA, MOFCOM and three other departments issued Opinions on Promoting Drug Pricing Reform. Under these opinions, beginning on June 1, 2015, the restrictions on the prices of the drugs that were subject to government pricing were cancelled except for narcotic drugs and Class I psychotropic drugs which are still subject to maximum factory prices and maximum retail prices set by the NDRC. The medical insurance regulatory authority now has the power to prescribe the standards, procedures, basis and methods of the payment for drugs paid by medical insurance funds. The prices of patented drugs are set through transparent and public negotiation among multiple parties. The prices for blood products not listed in the National Reimbursement Drug List, immunity and prevention drugs that are purchased by the Chinese government in a centralized manner, and AIDS antiviral drugs and contraceptives provided by the Chinese government for free, are set through a tendering process. Except as otherwise mentioned above, the prices for other drugs may be determined by the manufacturers and the operators on their own on the basis of production or operation costs and market supply and demand.

Centralized Procurement and Tenders

The Guiding Opinions concerning the Urban Medical and Health System Reform, promulgated on February 21, 2000, aim to provide medical services with reasonable price and quality to the public through the establishment of an urban medical and health system. One of the measures used to realize this aim is the regulation of the purchasing process of pharmaceutical products by medical institutions. Accordingly, the MOH and other relevant government authorities have promulgated a series of regulations and releases in order to implement the tender requirements.

According to the Notice on Issuing Certain Regulations on the Trial Implementation of Centralized Tender Procurement of Drugs by Medical Institutions promulgated on July 7, 2000 and the Notice on Further Improvement on the Implementation of Centralized Tender Procurement of Drugs by Medical Institutions promulgated on August 8, 2001, medical institutions established by county or higher level government are required to implement centralized tender procurement of drugs.

The MOH promulgated the Working Regulations of Medical Institutions for Procurement of Drugs by Centralized Tender and Price Negotiations (for Trial Implementation), or the Centralized Procurement Regulations, on March 13, 2002, and promulgated Sample Document for Medical Institutions for Procurement of Drugs by Centralized Tender and Price Negotiations (for Trial Implementation), or the Centralized Tender Sample Document in November 2001, as amended in 2010, to implement the tender process requirements and ensure the requirements are followed uniformly throughout the country. The Centralized Tender Regulations and the Centralized Tender Sample Document provide rules for the tender process and negotiations of the prices of drugs, operational procedures, a code of conduct and standards or measures of evaluating bids and negotiating prices. On January 17, 2009, the MOH, the NMPA and other four national departments jointly promulgated the Opinions on Further Regulating Centralized Procurement of Drugs by Medical Institutions. According to the notice, public medical institutions owned by the government at the county level or higher or owned by state-owned enterprises (including state-controlled enterprises) shall purchase pharmaceutical products through centralized procurement. Each provincial government shall formulate its catalogue of drugs subject to centralized procurement. Specifically, the procurement could be achieved through public tendering, online bidding, centralized price negotiations and online competition platform. Except for drugs in the National Essential Medicines List (the procurement of which shall comply with the relevant rules on National Essential Medicines List), certain pharmaceutical products which are under the national government’s special control and traditional Chinese medicines, in principle, all drugs used by public medical institutions shall be covered by the catalogue of drugs subject to centralized procurement. On July 7, 2010, the MOH and six other ministries and commissions jointly promulgated the Working Regulations of Medical Institutions for Centralized Procurement of Drugs to further regulate the centralized procurement of drugs and clarify the code of conduct of the parties in centralized drug procurement.

132

The centralized tender process takes the form of public tender operated and organized by provincial or municipal government agencies. The centralized tender process is in principle conducted once every year in all provinces and cities in China. Drug manufacturing enterprises, in principle, shall bid directly for the centralized tender process. Certain related parties, however, may be engaged to act as bidding agencies for the centralized tender process. Such intermediaries are not permitted to engage in the distribution of drugs and must have no conflict of interest with the organizing government agencies. The bids are assessed by a committee composed of pharmaceutical experts who will be randomly selected from a database of experts approved by the relevant government authorities. The committee members assess the bids based on a number of factors, including but not limited to, bid price, product quality, clinical effectiveness, qualifications and reputation of the manufacturer, and after-sale services. Only pharmaceuticals that have won in the centralized tender process may be purchased by public medical institutions funded by government in the relevant region.

4+7 Quality Consistency Evaluation

On November 15, 2018, China’s Joint Procurement Office published its Paper on Centralized Drug Procurement in “4+7 Cities,” known as the 4+7 Quality Consistency Evaluation process, or 4+7 QCE. The 4+7 QCE initiative is aimed at driving consolidation in the fragmented generic drug market in China. The 4+7 QCE initiative began as a pilot program in 11 cities: Beijing, Tianjin, Shanghai, Chongqing, Shenyang, Dalian, Xiamen, Guangzhou, Shenzhen, Chengdu and Xi’an. Under this pilot program, the public medical institutions in these 11 cities bulk-buy certain generic drugs together, forcing companies to bid for contracts and driving down prices. The 4+7 QCE initiative is expected to gradually expand to cover more cities and drugs over the coming years.

U.S. Coverage and Reimbursement

Successful sales of our products or drug candidates in the U.S. market, if approved, will depend, in part, on the extent to which our drugs will be covered by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. Patients who are provided with prescriptions as part of their medical treatment generally rely on such third-party payors to reimburse all or part of the costs associated with their prescriptions and therefore adequate coverage and reimbursement from such third-party payors are critical to new product success. These third-party payors are increasingly reducing reimbursements for medical drugs and services. Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic drugs. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. Decreases in third-party reimbursement for our drug candidates, if approved, or a decision by a third-party payor to not cover our drug candidates could reduce physician usage of such drugs and have a material adverse effect on our sales, results of operations and financial condition.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, established the Medicare Part D program to provide a voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities that provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Medicare payment for some of the costs of prescription drugs may increase demand for drugs for which we receive regulatory approval. However, any negotiated prices for our drugs covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

The American Recovery and Reinvestment Act of 2009 provides funding for the federal government to compare the effectiveness of different treatments for the same illness. The plan for the research was published in 2012 by the U.S. Department of Health and Human Services, the Agency for Healthcare Research and Quality and the National Institutes for Health, and periodic reports on the status of the research and related expenditures are made to Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors, if third-party payors do not consider a drug to be cost-effective compared to other available therapies, they may not cover such drugs as a benefit under their plans or, if they do, the level of payment may not be sufficient.

133

The Affordable Care Act, enacted in March 2010, has had a significant impact on the health care industry. The Affordable Care Act expanded coverage for the uninsured while at the same time containing overall healthcare costs. With regard to pharmaceutical products, the Affordable Care Act, among other things, addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs, and created a new Medicare Part D coverage gap discount program, in which, beginning in 2019, manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D. The Bipartisan Budget Act of 2018 made certain changes to Medicare Part D coverage, including changing the date when the Medicare Part D coverage gap is eliminated from 2020 to 2019, sunsetting the exclusion of biosimilars from the Medicare Part D coverage gap discount program in 2019 and reallocating responsibility for discounted pricing under the Medicare Part D coverage gap discount program from third-party payors to pharmaceutical companies. In December 2017, Congress also repealed the “individual mandate,” which was an Affordable Care Act requirement that individuals obtain healthcare insurance coverage or face a penalty. This repeal could affect the total number of patients who have coverage from third-party payors that reimburse for use of our products.

On December 14, 2018, a United States District Court judge in Texas ruled that the Affordable Care Act is unconstitutional in its entirety because of Congress’s repeal of the individual mandate. On December 18, 2019, the United States Court of Appeals for the Fifth Circuit affirmed the portion of the district court’s ruling declaring the individual mandate unconstitutional and remanded for the district court to conduct analysis in the first instance on which provisions of the statute are severable from it and thus remain intact. The litigation creates additional uncertainty around the Affordable Care Act’s ultimate fate.

In addition, other legislative and regulatory changes have been proposed and adopted in the United States since the Affordable Care Act was enacted that affect reimbursement for prescription drugs. On August 2, 2011, the Budget Control Act of 2011 among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, started in April 2013, and, due to subsequent legislative amendments, will stay in effect through 2025 unless additional Congressional action is taken. On January 2, 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which among other things, also reduced Medicare payments to several providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

Recent regulations adopted by the Centers for Medicare & Medicaid Services grant Medicare Part B plans authority to apply new cost control measures to steer patients toward lower-priced drug products prior to covering non-preferred, more expensive products. This could potentially have the result of reducing coverage of our products under Medicare Part B.

In addition, other proposed legislative and regulatory changes could affect reimbursement for prescription drugs. In January 2017, the Medicare Prescription Drug Price Negotiation Act was proposed in Congress, which would require the government to negotiate Medicare prescription drug prices with pharmaceutical companies. In October 2017, a similar bill, the Medicare Drug Price Negotiation Act of 2017 was proposed in Congress. In November 2017, the Centers for Medicare & Medicaid Services announced a Final Rule that would adjust the applicable payment rate as necessary for certain separately payable drugs and biologicals acquired under the 340B Program from average sales price plus 6% to average sales price minus 22.5%. Congress and the U.S. administration continue to evaluate other proposals that could affect third-party reimbursement for our drug candidates, if approved. In December 2019, for example, the U.S. Department of Health and Human Services and the FDA issued a proposed rule and draft guidance concerning two new pathways for importing lower-cost drugs into the United States. The proposed rule, if finalized, would allow certain prescription drugs to be imported from Canada. The draft guidance describes procedures for drug manufacturers to facilitate the importation of FDA-approved drugs and biologics manufactured abroad and originally intended for sale in a foreign country into the United States. Additionally, President Trump’s administration has proposed to establish an international pricing index that would tie domestic prices for certain drugs and biologics to the prices in other countries with more aggressive drug price regulation. Such regulatory changes could have the effect of lowering the level of coverage or reimbursement for our products under Medicare Part B.

134

Rest of the World Coverage and Reimbursement

In some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of medicinal drugs for which their national health insurance systems provide reimbursement and to control the prices of medicinal drugs for human use. A member state may approve a specific price for the medicinal drug or it may instead adopt a system of direct or indirect controls on the profitability of our company placing the medicinal drug on the market. Historically, drugs launched in the European Union do not follow price structures of the United States and generally tend to be significantly lower.

Other Healthcare Laws

Other PRC Healthcare Laws

Advertising of Pharmaceutical Products

Pursuant to the Provisions for Drug Advertisement Examination, which were promulgated on March 13, 2007, effective on May 1, 2007 and subsequently amended on December 21, 2018, an enterprise seeking to advertise its drugs must apply for an advertising approval code. The validity term of an advertisement approval number for pharmaceutical drugs is one year. The content of an approved advertisement may not be altered without prior approval. Where any alteration to the advertisement is needed, a new advertisement approval number shall be obtained.

Packaging of Pharmaceutical Products

According to the Measures for The Administration of Pharmaceutical Packaging, effective on September 1, 1988, pharmaceutical packaging must comply with the provisions of the national standard and professional standard. If there are no standards, the enterprise can formulate its own standard after obtaining the approval of the provincial level food and drug administration or bureau of standards. The enterprise shall reapply for the relevant authorities if it needs to change the packaging standard. Drugs without packing must not be sold in PRC (except for drugs needed by the army).

Labor Protection

Under the Labor Law of the PRC, effective on January 1, 1995 and subsequently amended on August 27, 2009 and December 29, 2018, the Labor Contract Law of the PRC, effective on January 1, 2008 and subsequently amended on December 28, 2012, and the Implementing Regulations of the Labor Contract Law of the PRC, effective on September 18, 2008, employers must establish a comprehensive management system to protect the rights of their employees, including a system governing occupational health and safety to provide employees with occupational training to prevent occupational injury, and employers are required to truthfully inform prospective employees of the job description, working conditions, location, occupational hazards and status of safe production as well as remuneration and other conditions as requested by the Labor Contract Law of the PRC.

Pursuant to the Law of Manufacturing Safety of the People’s Republic of China effective on November 1, 2002 and subsequently amended on December 1, 2014, manufacturers must establish a comprehensive management system to ensure manufacturing safety in accordance with applicable laws and regulations. Manufacturers not meeting relevant legal requirements are not permitted to commence their manufacturing activities.

Pursuant to the Administrative Measures Governing the Production Quality of Pharmaceutical Products effective on March 1, 2011, manufacturers of pharmaceutical products are required to establish production safety and labor protection measures in connection with the operation of their manufacturing equipment and manufacturing process.

135

Pursuant to applicable PRC laws, rules and regulations, including the Social Insurance Law which became effective on July 1, 2011 and subsequently amended on December 29, 2018, the Interim Regulations on the Collection and Payment of Social Security Funds which became effective on January 22, 1999 and subsequently amended on March 24, 2019, the Interim Measures concerning the Maternity Insurance which became effective on January 1, 1995 and the Regulations on Work-related Injury Insurance which became effective on January 1, 2004 and were subsequently amended on December 20, 2010, employers are required to contribute, on behalf of their employees, to a number of social security funds, including funds for basic pension insurance, unemployment insurance, basic medical insurance, work-related injury insurance, and maternity insurance. If an employer fails to make social insurance contributions timely and in full, the social insurance collecting authority will order the employer to make up outstanding contributions within the prescribed time period and impose a late payment fee at the rate of 0.05% per day from the date on which the contribution becomes due. If such employer fails to make social insurance registration, the social insurance collecting authority will order the employer to correct within the prescribed time period. The relevant administrative department may impose a fine equivalent to three times the overdue amount and management personnel who are directly responsible can be fined RMB500 ($73.10) to RMB3,000 ($438.60) if the employer fails to correct within the prescribed time period.

Commercial Bribery

Medical production and operation enterprises involved in criminal, investigation or administrative procedure for commercial bribery will be listed in the Adverse Records of Commercial Briberies by provincial health and family planning administrative department. Pursuant to the Provisions on the Establishment of Adverse Records of Commercial Briberies in the Medicine Purchase and Sales Industry enforced on March 1, 2014 by the National Health and Family Planning Commission, if medical production and operation enterprises are listed into the Adverse Records of Commercial Briberies for the first time, their production shall not be purchased by public medical institutions, and medical and health institutions receiving financial subsidies in local province in two years from public of the record, and public medical institutions, and medical and health institutions receiving financial subsidies in other provinces shall lower their rating in bidding or purchasing process. If medical production and operation enterprises are listed into the Adverse Records of Commercial Briberies twice or more times in five years, their production may not be purchased by public medical institutions, and medical and health institutions receiving financial subsidies nationwide in two years from public of the record.

As advised by our PRC legal advisor, from a PRC law perspective, a pharmaceutical company will not be penalized by the relevant PRC government authorities merely by virtue of having contractual relationships with distributors or third-party promoters who are engaged in bribery activities, so long as such pharmaceutical company and its employees are not utilizing the distributors or third-party promoters for the implementation of, or acting in conjunction with them in, the prohibited bribery activities. In addition, a pharmaceutical company is under no legal obligation to monitor the operating activities of its distributors and third-party promoters, and will not be subject to penalties or sanctions by relevant PRC government authorities as a result of failure to monitor their operating activities.

Product Liability

In addition to the strict new drug approval process, certain PRC laws have been promulgated to protect the rights of consumers and to strengthen the control of medical products in the PRC. Under current PRC law, manufacturers and vendors of defective products in the PRC may incur liability for loss and injury caused by such products. Pursuant to the General Principles of the Civil Law of the PRC, or the PRC Civil Law, promulgated on April 12, 1986 and amended on August 27, 2009, a defective product which causes property damage or physical injury to any person may subject the manufacturer or vendor of such product to civil liability for such damage or injury.

On February 22, 1993 the Product Quality Law of the PRC, or the Product Quality Law, was promulgated to supplement the PRC Civil Law aiming to define responsibilities for product quality, to protect the legitimate rights and interests of the end-users and consumers and to strengthen the supervision and control of the quality of products. The Product Quality Law was amended by the Ninth National People’s Congress on July 8, 2000 and was later amended by the Eleventh National People’s Congress on August 27, 2009 and the Thirteenth National People’s Congress on December 29, 2018. Pursuant to the amended Product Quality Law, manufacturers who produce defective products may be subject to civil or criminal liability and have their business licenses revoked.

136

The Law of the PRC on the Protection of the Rights and Interests of Consumers was promulgated on October 13, 1993 and was amended on October 25, 2013 to protect consumers’ rights when they purchase or use goods and accept services. All business operators must comply with this law when they manufacture or sell goods and/or provide services to customers. Under the amendment on October 25, 2013, all business operators shall pay high attention to protect the customers’ privacy which they obtain during the business operation. In addition, in extreme situations, pharmaceutical product manufacturers and operators may be subject to criminal liabilities under applicable laws of the PRC if their goods or services lead to the death or injuries of customers or other third parties.

PRC Tort Law

Under the Tort Law of the PRC which became effective on July 1, 2010, if damages to other persons are caused by defective products that are resulted from the fault of a third party such as the parties providing transportation or warehousing, the producers and the sellers of the products have the right to recover their respective losses from such third parties. If defective products are identified after they have been put into circulation, the producers or the sellers shall take remedial measures such as issuance of warning, recall of products, etc. in a timely manner. The producers or the sellers shall be liable under tort if they cause damages due to their failure to take remedial measures in a timely manner or have not made efforts to take remedial measures, thus causing damages. If the products are produced and sold with known defects, causing deaths or severe damage to the health of others, the infringed party shall have the right to claim respective punitive damages in addition to compensatory damages.

Other PRC National- and Provincial-Level Laws and Regulations

We are subject to changing regulations under many other laws and regulations administered by governmental authorities at the national, provincial and municipal levels, some of which are or may become applicable to our business. Our hospital customers are also subject to a wide variety of laws and regulations that could affect the nature and scope of their relationships with us.

For example, regulations control the confidentiality of patients’ medical information and the circumstances under which patient medical information may be released for inclusion in our databases, or released by us to third parties. These laws and regulations governing both the disclosure and the use of confidential patient medical information may become more restrictive in the future.

We also comply with numerous additional state and local laws relating to matters such as safe working conditions, manufacturing practices, environmental protection and fire hazard control. We believe that we are currently in compliance with these laws and regulations; however, we may be required to incur significant costs to comply with these laws and regulations in the future. Unanticipated changes in existing regulatory requirements or adoption of new requirements could therefore have a material adverse effect on our business, results of operations and financial condition.

Other U.S. Healthcare Laws

We may also be subject to healthcare regulation and enforcement by the U.S. federal government and the states where we may market our drug candidates, if approved. These laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security and physician sunshine laws and regulations.

Anti-Kickback Statute

The federal Anti-Kickback Statute prohibits, among other things, any person from knowingly and willfully offering, soliciting, receiving or providing remuneration, directly or indirectly, to induce either the referral of an individual, for an item or service or the purchasing or ordering of a good or service, for which payment may be made under federal healthcare programs such as the Medicare and Medicaid programs. The majority of states also have anti-kickback laws, which establish similar prohibitions and in some cases may apply to items or services reimbursed by any third-party payor, including commercial insurers. The Anti-Kickback Statute is subject to evolving interpretations. In the past, the government has enforced the Anti-Kickback Statute to reach large settlements with healthcare companies based on sham consulting and other financial arrangements with physicians. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act.

137

False Claims

Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S. government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of the government. Analogous state law equivalents may apply and may be broader in scope than the federal requirements. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the False Claims Act, and the accompanying threat of significant liability, in its investigation and prosecution of pharmaceutical and biotechnology companies throughout the U.S., for example, in connection with the promotion of products for unapproved uses and other sales and marketing practices. The government has obtained multi-million and multi-billion dollar settlements under the False Claims Act in addition to individual criminal convictions under applicable criminal statutes. Given the significant size of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ and manufacturers’ compliance with applicable fraud and abuse laws.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, also created new federal criminal statutes that prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

Payments to Physicians

There has also been a recent trend of increased federal and state regulation of payments made to physicians and other healthcare providers. The Affordable Care Act, among other things, imposes new reporting requirements on drug manufacturers for payments made by them to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 per year (or up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of value or ownership or investment interests that are not timely, accurately and completely reported in an annual submission. Drug manufacturers were required to begin collecting data on August 1, 2013 and submit reports to the government by March 31, 2014 and June 30, 2014, and the 90th day of each subsequent calendar year. Certain states also mandate implementation of compliance programs, impose restrictions on drug manufacturer marketing practices and/or require the tracking and reporting of gifts, compensation and other remuneration to physicians.

Data Privacy and Security

We may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as amended by the Health Information Technology and Clinical Health Act, or HITECH, and their respective implementing regulations, including the final omnibus rule published on January 25, 2013, imposes specified requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates,” defined as independent contractors or agents of covered entities that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of personal health information in certain circumstances, many of which differ from each other in significant ways, thus complicating compliance efforts.

PRC Regulation of Foreign Currency Exchange, Offshore Investment and State-Owned Assets

PRC Foreign Currency Exchange

Foreign currency exchange regulation in China is primarily governed by the following rules:

● Foreign Currency Administration Rules (1996), as last amended on August 5, 2008, or the Exchange Rules; and

138

● Administration Rules of the Settlement, Sale and Payment of Foreign Exchange (1996), or the Administration Rules.

Under the Exchange Rules, the renminbi is convertible for current account items, including the distribution of dividends, interest payments, trade and service-related foreign exchange transactions. Conversion of renminbi for capital account items, such as direct investment, loan, security investment and repatriation of investment, however, is still subject to the SAFE.

Under the Administration Rules, foreign-invested enterprises may only buy, sell and/or remit foreign currencies at those banks authorized to conduct foreign exchange business after providing valid commercial documents and, in the case of capital account item transactions, obtaining approval from the SAFE. Capital investments by foreign-invested enterprises outside of China are also subject to limitations, which include approvals by the MOFCOM, the SAFE and the NDRC.

Pursuant to the Circular on Further Improving and Adjusting the Direct Investment Foreign Exchange Administration Policies, or Circular 59, promulgated by the SAFE on November 19, 2012 and became effective on December 17, 2012, approval is not required for the opening of and payment into foreign exchange accounts under direct investment, for domestic reinvestment with legal income of foreign investors in China. Circular 59 also simplified the capital verification and confirmation formalities for Chinese foreign invested enterprises and the foreign capital and foreign exchange registration formalities required for the foreign investors to acquire the equities of Chinese party and other items. Circular 59 further improved the administration on exchange settlement of foreign exchange capital of Chinese foreign invested enterprises.

Foreign Exchange Registration of Offshore Investment by PRC Residents

In July 2014, the SAFE issued the Notice on Relevant Issues Concerning Foreign Exchange Administration for PRC Residents to Engage in Offshore Investment and Financing and Round Trip Investment via Special Purpose Vehicles, or Circular 37, and its implementation guidelines, which abolishes and supersedes the SAFE’s Circular on Relevant Issues Concerning Foreign Exchange Administration for PRC Residents to Engage in Financing and Round Trip Investment via Overseas Special Purpose Vehicles, or Circular 75. Pursuant to Circular 37 and its implementation guidelines, PRC residents (including PRC institutions and individuals) must register with local branches of the SAFE in connection with their direct or indirect offshore investment in an overseas special purpose vehicle, or SPV, directly established or indirectly controlled by PRC residents for the purposes of offshore investment and financing with their legally owned assets or interests in domestic enterprises, or their legally owned offshore assets or interests. Such PRC residents are also required to amend their registrations with the SAFE when there is a significant change to the SPV, such as changes of the PRC individual resident’s increase or decrease of its capital contribution in the SPV, or any share transfer or exchange, merger, division of the SPV. Failure to comply with the registration procedures set forth in Circular 37 may result in restrictions being imposed on the foreign exchange activities of the relevant onshore company, including the payment of dividends and other distributions to its offshore parent or affiliate, the capital inflow from the offshore entities and settlement of foreign exchange capital, and may also subject relevant onshore company or PRC residents to penalties under PRC foreign exchange administration regulations.

In February 2012, the SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly Listed Companies. Based on this regulation, directors, supervisors, senior management and other employees of domestic subsidiaries or branches of a company listed on an overseas stock market who are PRC citizens or who are non-PRC citizens residing in China for a continuous period of not less than one year, subject to a few exceptions, are required to register with the SAFE or its local counterparts by following certain procedures if they participate in any stock incentive plan of the company listed on an overseas stock market. Foreign exchange income received from the sale of shares or dividends distributed by the overseas listed company may be remitted into a foreign currency account of such PRC citizen or be exchanged into renminbi. Our PRC citizen employees who have been granted share options have been subject to these rules due to our admission to trading on the AIM market of the London Stock Exchange and the listing of our ADSs on Nasdaq.

139

Regulation on Investment in Foreign-invested Enterprises

Pursuant to PRC law, the registered capital of a limited liability company is the total capital contributions subscribed for by all the shareholders as registered with the company registration authority. A foreign-invested enterprise also has a total investment limit that is approved by or filed with the MOFCOM or its local counterpart by reference to both its registered capital and expected investment scale. The difference between the total investment limit and the registered capital of a foreign-invested enterprise or the cross-border financing risk weighted balance calculated based on a formula by the PBOC represents the foreign debt financing quota to which it is entitled (i.e., the maximum amount of debt which the company may borrow from a foreign lender). A foreign-invested enterprise is required to obtain approval from or file with the MOFCOM or its local counterpart for any increases to its total investment limit. In accordance with these regulations, we and our joint venture partners have contributed financing to our PRC subsidiaries and joint ventures in the form of capital contributions up to the registered capital amount and/or in the form of shareholder loans up to the foreign debt quota. According to the financing needs of our PRC subsidiaries and joint ventures, we and our joint venture partners have requested and received approvals from the government authorities for increases to the total investment limit for certain of our PRC subsidiaries and joint ventures from time to time. As a result, these regulations have not had a material impact to date on our ability to finance such entities.

Regulation on Dividend Distribution

The principal regulations governing distribution of dividends paid by wholly foreign-owned enterprises include:

● Company Law of the PRC (1993), as amended in 1999, 2004, 2005, 2013 and 2018;

● Foreign Investment Law of the PRC; and

● Implementation Rules for the Foreign Investment Law.

● Under these laws and regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise in China is required to set aside at least 10.0% of its after-tax profit based on PRC accounting standards each year to its general reserves until the accumulative amount of such reserves reach 50.0% of its registered capital. These reserves are not distributable as cash dividends. The board of directors of a foreign-invested enterprise has the discretion to allocate a portion of its after-tax profits to staff welfare and bonus funds, which may not be distributed to equity owners except in the event of liquidation.

Filings and Approvals Relating to State-Owned Assets

Pursuant to applicable PRC state-owned assets administration laws and regulations, incorporating a joint venture that will have investments of assets that are both state-owned and non-state-owned and investing in an entity that was previously owned by a state-owned enterprise require the performance of an assessment of the relevant state-owned assets and the filing of the assessment results with the competent state-owned assets administration, finance authorities or other regulatory authorities and, if applicable, the receipt of approvals from such authorities.

Our joint venture partners were required to perform a state-owned asset assessment when Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan were incorporated and our joint venture partners contributed state-owned assets, and when we invested in Hutchison Sinopharm, which was previously wholly-owned by Sinopharm, a state-owned enterprise. In all three instances, our joint venture partners have informed us that they have duly filed the relevant state-owned asset assessment results with, and obtained the requisite approvals from, the relevant governmental authorities as required by the foregoing laws and regulations. Accordingly, we believe that such joint ventures are in full compliance with all applicable laws and regulations governing the administration of state-owned assets, although we are currently unable to obtain copies of certain filing and approval documents of our joint venture partners due to their internal confidentiality constraints. We have not received any notice of warning or been subject to any penalty or other disciplinary action from the relevant governmental authorities with respect to the applicable laws and regulations governing the administration of state-owned assets.

A.    Operating Results.

Overview

We are an innovative, commercial-stage biopharmaceutical company based in China aiming to become a fully integrated global leader in the discovery, development and commercialization of targeted therapies and immunotherapies for the treatment of cancer and immunological diseases. We conduct our business through two platforms, namely our Innovation Platform and our Commercial Platform.

Through our Innovation Platform, our team of approximately 500 scientists and staff has created and developed a deep portfolio of eight drug candidates, five of which are in global clinical development. These drug candidates are being developed to treat a wide spectrum of diseases, including solid tumors, hematological malignancies and immunological diseases which we believe may address significant unmet medical needs and represent large commercial opportunities. Many of these drugs have the potential to be first-in-class or best-in-class therapies. Our success in research and development has led to partnerships with leading global pharmaceutical companies, including AstraZeneca and Eli Lilly. We and our collaboration partners have invested over $760 million in our Innovation Platform as of December 31, 2019, with almost all of these funds used for research and development expenses for the development of our drug candidates. Net loss attributable to our company from our Innovation Platform was $51.9 million, $104.4 million and $133.2 million for the years ended December 31, 2017, 2018 and 2019, respectively.

We have also established a profitable commercial infrastructure in China to manufacture, market and distribute prescription drugs (under our Prescription Drugs business) and consumer health products (under our Consumer Health business) which together form our Commercial Platform. Net income attributable to our company generated from our Commercial Platform was $40.0 million, $43.4 million and $47.4 million for the years ended December 31, 2017, 2018 and 2019, respectively. In addition to helping to fund our Innovation Platform, we anticipate that we will be able to utilize the know-how and infrastructure from our Prescription Drugs business to support the launch of products from our Innovation Platform if they are approved by the NMPA for use in China. Our Commercial Platform also includes our Consumer Health business, which is a profitable and cash flow generating business selling primarily over-the-counter pharmaceutical products (through our non-consolidated joint venture Hutchison Baiyunshan) and a range of health-focused consumer products.

Our consolidated revenue was $241.2 million, $214.1 million and $204.9 million for the years ended December 31, 2017, 2018 and 2019, respectively. Net loss attributable to our company was $26.7 million, $74.8 million and $106.0 million for the years ended December 31, 2017, 2018 and 2019 respectively.

Basis of Presentation

Our consolidated statements of operations data presented herein for the years ended December 31, 2019, 2018 and 2017 and our consolidated balance sheet data presented herein as of December 31, 2019 and 2018 have been derived from our audited consolidated financial statements, which were prepared in accordance with U.S. GAAP, and should be read in conjunction with those statements which are included elsewhere in this annual report.

Our Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan joint ventures under our Commercial Platform and our Nutrition Science Partners joint venture under our Innovation Platform (until December 9, 2019 when it was purchased by us and became our consolidated subsidiary) are accounted for under the equity accounting method as non-consolidated entities in our consolidated financial statements, and their consolidated financial statements were prepared in accordance with IFRS as issued by the IASB and audited under auditing standards generally accepted in the U.S. and included elsewhere in this annual report.

We have two strategic business units, our Innovation Platform and our Commercial Platform, that offer different products and services. Our Commercial Platform is further segregated into the two core business areas of Prescription Drugs and Consumer Health. The presentation of financial data for our business units excludes certain unallocated costs attributed to expenses incurred by our corporate head office. For more information on our corporate structure, see Item 4.A. “History and Development of the Company.”

142

Factors Affecting our Results of Operations

Innovation Platform

Research and Development Expenses

We believe our ability to successfully develop innovative drug candidates through our Innovation Platform will be the primary factor affecting our long-term competitiveness, as well as our future growth and development. Creating high quality global first-in-class or best-in-class drug candidates requires a significant investment of resources over a prolonged period of time, and a core part of our strategy is to continue making sustained investments in this area. As a result of this commitment, our pipeline of drug candidates has been steadily advancing and expanding, with eight clinical-stage drug candidates, five of which are in global clinical development. For more information on the nature of the efforts and steps necessary to develop our drug candidates, see Item 4.B. “Business Overview—Our Clinical Pipeline” and “Business Overview—Regulation.”

The drug candidates of our Innovation Platform are still in development, and we have incurred and will continue to incur significant research and development costs for pre-clinical studies and clinical trials. We expect that our research and development expenses will significantly increase in future periods in line with the advancement and expansion of the development of our drug candidates.

Innovation Platform expenses include:

● employee compensation related expenses, including salaries, benefits and equity compensation expense;

● expenses incurred for payments to CROs, investigators and clinical trial sites that conduct our clinical studies;

● the cost of acquiring, developing, and manufacturing clinical study materials;

● facilities, depreciation, and other expenses, which include office leases and other overhead expenses; and

● costs associated with pre-clinical activities and regulatory operations.

Research and development costs incurred by our Innovation Platform totaled $75.5 million, $114.2 million and $138.2 million for the years ended December 31, 2017, 2018 and 2019, respectively, representing approximately 31.3%, 53.3% and 67.4% of our total consolidated revenue for the respective period. These figures do not include payments made by our collaboration partners directly to third parties to help fund the research and development of our drug candidates.

We have historically been able to fund the research and development expenses for our Innovation Platform via a range of sources, including payments received from our collaboration partners, cash flows generated from and dividend payments from our Commercial Platform, the proceeds raised from our initial public offering on the AIM market of the London Stock Exchange, our initial public offering and follow-on offerings on Nasdaq and banks borrowings.

This diversified approach to funding allows us to not depend on any one method of funding for our Innovation Platform, thereby reducing the risk that sufficient financing will be unavailable as we continue to accelerate the development of our drug candidates.

For more information on the research and development expenses incurred for the development of our drug candidates, see “—Key Components of Results of Operations—Cost of Sales and Operating Expenses—Research and Development Expenses.”

Our Ability to Commercialize Our Drug Candidates

Our ability to generate revenue from our drug candidates depends on our ability to successfully complete clinical trials for our drug candidates and obtain regulatory approvals for them in the United States, Europe, China and other major markets.

143

We believe that our risk-balanced strategy of focusing on drug development for novel but relatively well-characterized targets and for validated targets, in combination with our development of multiple drug candidates concurrently and testing them for multiple indications and in combinations with other drugs, enhances the likelihood that our research and development efforts will yield successful drug candidates. Nonetheless, we cannot be certain if any of our drug candidates will receive regulatory approvals. Even if such approvals are granted, we will need to thereafter establish manufacturing supply and engage in extensive marketing prior to generating any revenue from such drugs, and the ultimate commercial success of our drugs will depend on their acceptance by patients, the medical community and third-party payors and their ability to compete effectively with other therapies on the market.

As a first step towards commercialization, we have incurred a total of approximately $12.0 million in capital expenditures between 2013 and 2019 to establish a standard manufacturing (formulation) facility in Suzhou, China, which now produces commercial supplies of Elunate (the brand name for fruquintinib). During 2019, we began building an internal oncology sales team to prepare for the potential launch of surufatinib in China, if approved. However, we have no history of successfully commercializing our internally developed drug candidates, which makes it difficult to evaluate our future prospects.

The competitive environment is also an important factor with the commercial success of our potential global first-in-class products, such as savolitinib and HMPL-523, depending on whether we are able to gain regulatory approvals and quickly bring such products to market ahead of competing drug candidates being developed by other companies.

For our drug candidates where we retain all rights worldwide, which currently include surufatinib, HMPL-523, HMPL-689, epitinib, theliatinib, HMPL-453 and HMPL-306, if they remain unpartnered, we will be able to retain all the profits if any of them are successfully commercialized, though we will need to bear all the costs associated with such drug candidates. Conversely, as discussed below, for our drug candidates which are subject to collaboration partnerships, our collaboration partners provide funding for development of the drug candidates but are entitled to retain a significant portion of any revenue generated by such drug candidates.

Our Collaboration Partnerships

Our results of operations have been, and we expect them to continue to be, affected by our collaborations with third parties for the development and commercialization of certain of our drug candidates. Currently, these include savolitinib (collaboration with AstraZeneca) and fruquintinib (collaboration with Eli Lilly). In addition to providing us with clinical and regulatory support, the payments received from these collaborations have been critical to our ability to develop and quickly advance the pre-clinical and clinical studies of multiple drug candidates concurrently.

In particular, our partners cover a portion of our research and development costs for drug candidates developed in collaboration with them. For example, under our collaboration agreement with AstraZeneca, it is responsible for a significant portion of the development costs for savolitinib. However, in August 2016 we and AstraZeneca amended our collaboration agreement whereby we agreed to contribute additional funding for the research and development of savolitinib in return for a larger share of the upside if and when savolitinib is approved. Under our original collaboration agreement with Eli Lilly, it was responsible for a significant portion of all fruquintinib development costs in China. Under the terms of our December 2018 amendment to this agreement, we are responsible for all development costs for fruquintinib in new life cycle indications. We believe a material portion of such costs will be borne by third-party pharmaceutical companies, such as PD-1 manufacturers Innovent and Genor, with whom we collaborate to develop fruquintinib combination therapies in new life cycle indications.

In addition, under our licensing, co-development and commercialization agreements, we received upfront payments upon our entry into such agreements and milestone payments upon the achievement of certain development, regulatory and commercial milestones payments for our provision of research and development services for the relevant drug candidate as well as royalties and revenue from products sales of Elunate which we manufacture and sell to Eli Lilly at cost. Revenue recognized in our consolidated financial statements from such agreements with AstraZeneca and Eli Lilly totaled $26.3 million, $33.4 million and $26.3 million for the years ended December 31, 2017, 2018 and 2019, respectively. In addition, income from research and development services from both other third parties and related parties totaled $9.7 million, $7.8 million and $0.5 million for the years ended December 31, 2017, 2018 and 2019, respectively.

144

The achievement of milestones for our drug candidates, which is dependent on the outcome of clinical studies, is subject to a high degree of uncertainty and, as a result, we cannot reasonably estimate when we can expect to receive future milestone payments, or at all. For more information on our revenue recognition policies, see “—Critical Accounting Policies and Significant Judgments and Estimates—Revenue recognition—Innovation Platform.” If we are unable to achieve development milestones for our drug candidates or if our partners were to terminate their collaborative agreements with us, payments for research and development services could also be affected.

Our collaboration partners are entitled to a significant proportion of any future revenue from commercialization of our drug candidates developed in collaboration with them, as well as a degree of influence over the clinical development process for such drug candidates. We may not be able to negotiate additional collaborations on a timely basis, on acceptable terms, or at all, which would affect our ability to receive additional upfront, milestone or service payments in the future. For more information regarding our collaboration agreements, see Item 4.B. “Business Overview—Overview of Our Collaborations.”

Commercial Platform

China Government Insurance Reimbursement and Drug Pricing Policies

Revenue of our Commercial Platform is affected by the sales volume and pricing of our current and future internally developed drug candidates, if approved. Eligible participants in the government-sponsored medical insurance programs in China are entitled to reimbursement for varying percentages of the cost for any medicines that are included in applicable reimbursement lists. Factors that affect the inclusion of medicines in China’s National Reimbursement Drug List and any other applicable reimbursement list may include whether the medicine is consumed in large volumes and commonly prescribed for clinical use in China and whether it is considered to be important in meeting the basic healthcare needs of the general public. For more information, see Item 4.B. “Business Overview—Coverage and Reimbursement—PRC Coverage and Reimbursement.” The inclusion of a medicine in the National Reimbursement Drug List or other applicable reimbursement lists can substantially improve the sales volume of the medicine due to the availability of third-party reimbursements; while, on the other hand, subjects it to price controls in the form of fixed retail prices or retail price ceilings, as well as periodical price adjustments by the regulatory authorities. Such price controls, especially downward price adjustments, may negatively affect the retail price of our drug candidates. On balance, we believe that, if priced appropriately, the benefit of the inclusion of our drug candidates in the National Reimbursement Drug List and other applicable reimbursement lists outweighs the cost of such inclusion. Starting on January 1, 2020, Elunate was included on China’s National Reimbursement Drug List at a 63% discount to its initial retail price, paving the way to significantly broaden access for advanced colorectal cancer patients and rapidly build penetration in China in the coming years.

Revenue of our Commercial Platform is affected by the revenue generated by our Prescription Drugs business and our non-consolidated joint venture Hutchison Baiyunshan, part of our Consumer Health business, which is directly affected by the sales volume and pricing of their own-brand prescription and over-the-counter pharmaceutical products as well as third-party pharmaceutical products. The sales volume of the products sold by these businesses is driven in part by the level of Chinese government spending on healthcare and the coverage of Chinese government medical insurance schemes, which is correlated with patient reimbursements for drug purchases, all of which have increased significantly in recent years as part of healthcare reforms in China. The sales volume of pharmaceutical products in China is also influenced by their representation on the National Reimbursement Drug List, which determines eligibility for drug reimbursement, as well as their representation on the National Essential Medicines List, which mandates distribution of drugs in China. Substantially all pharmaceutical products manufactured and sold by Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan in 2019 were capable of being reimbursed under the National Reimbursement Drug List as of December 31, 2019. In addition, among these two joint ventures an aggregate of 46 drugs, of which 11 were in active production as of December 31, 2019, have been included on the National Essential Medicines List. She Xiang Bao Xin pills, Shanghai Hutchison Pharmaceuticals’ top-selling drug, is one of the few proprietary drugs included on the National Essential Medicines List.

The National Reimbursement Drug List and the National Essential Medicines List are subject to revision by the government from time to time, and our results could be materially and adversely affected if any of our products are removed from the National Reimbursement Drug List or the National Essential Medicines List. For more information, see Item 3.D. “Risk Factors—Risks Relating to Our Commercial Platform and Sales of Our Commercial-stage Drug Candidates—Reimbursement may not be available for the products currently sold through our Commercial Platform or our drug candidates in China, the United States or other countries, which could diminish our sales or affect our profitability.”

145

The sale prices of certain pharmaceutical products sold by our Commercial Platform joint ventures are also subject to Chinese government’s price controls. In April 2014, the China National Development and Reform Commission, or the NDRC, announced a new Low Price Drug List, or LPDL, aimed at making certain low-price pharmaceuticals more profitable for manufacturers to produce. The LPDL established caps for the daily cost of chemical pharmaceuticals at less than RMB3.0 ($0.43) per day and of traditional Chinese medicine pharmaceuticals at less than RMB5.0 ($0.71) per day. The LPDL gives manufacturers flexibility to increase prices within the caps and exempts LPDL pharmaceuticals from hospital tenders. As of the end of 2019, Hutchison Baiyunshan’s two top-selling products, Fu Fang Dan Shen tablets and Banlangen, cost consumers RMB1.9 ($0.27) per day and RMB2.2 ($0.31) per day, respectively, and Shanghai Hutchison Pharmaceuticals’ two top-selling products, She Xiang Bao Xin pills and Danning tablets, cost RMB4.4 ($0.63) per day and RMB4.2 ($0.60) per day, respectively, each below the established caps for traditional Chinese medicine pharmaceuticals under the LPDL. As a result, we do not expect the LPDL to exert downward pressure on the pricing of these products unless the government makes significant downward adjustments to the LPDL price caps in the future.

Subject to customer demand, we have the ability to increase the prices for these products under the current LPDL price caps. For example, during 2016 we began to phase in, on a province-by-province basis, a 30% price increase for She Xiang Bao Xin pills from RMB2.7 ($0.38) per day to RMB3.5 ($0.50) per day, and in 2017 and 2018 we further increased the price to RMB4.0 ($0.57) per day to RMB4.4 ($0.63). In addition, the pricing of Shanghai Hutchison Pharmaceuticals’ prescription drugs are influenced by the outcomes of periodic provincial and municipal tender processes organized by the various provincial or municipal government agencies in China. For more information, see Item 4.B. “Business Overview—Coverage and Reimbursement—PRC Coverage and Reimbursement.”

Ability of Prescription Drugs Business to Effectively Market Own Brand and Third Party Drugs

A key component of our Commercial Platform is the extensive marketing network of our Prescription Drugs business operated by our joint ventures Shanghai Hutchison Pharmaceuticals and Hutchison Sinopharm, which includes approximately 2,400 medical sales representatives covering hospitals in over 330 cities and towns in China.  Our results of operations are impacted by the effectiveness of this network, including the ability of Shanghai Hutchison Pharmaceuticals to generate sales of She Xiang Bao Xin pills, which represented approximately 86%, 85% and 88% of its total revenue for the years ended December 31, 2017, 2018 and 2019, respectively.  In addition, in recent years Hutchison Sinopharm has been increasingly focused on providing distribution and commercialization services for prescription drugs licensed from third parties, such as Concor and we are building an oncology sales and marketing team which we plan to utilize for our internally developed drugs for which we have commercialization rights, if approved.  

If the marketing efforts of these joint ventures to doctors and hospitals are not successful, our revenue and profitability may be negatively affected.  Moreover, if we are unsuccessful in marketing any third party drugs, it may adversely affect our ability to enter into commercialization arrangements on acceptable terms, gain rights to market additional third-party drugs or prevent us from expanding the geographic scope of existing arrangements.  We also have no history of commercializing our internally developed drug candidates, which makes it difficult to evaluate our future prospects.

Seasonality

The results of operations of our Commercial Platform are also affected by seasonal factors. Our Commercial Platform typically experiences higher profits in the first half of the year due to the sale cycles of our distributors, whereby they typically increase their inventories at the beginning of each year. In addition, in the second half of each year, our Commercial Platform typically spends more on marketing activities to help reduce such inventory held by distributors. We do not experience material seasonal variations in the results of our Innovation Platform.

Overall Economic Growth and Consumer Spending Patterns

The results of operations and growth of our Consumer Health business depend in part on continuing economic growth and increasing income and health awareness of consumers in Asia. Although economic growth in China has slowed in recent periods, it achieved an annual growth rate in real gross domestic product of approximately 5.8% in 2019 according to the International Monetary Fund. As per capita disposable income has increased, consumer spending has also increased, and consumers in China have tended to be more health conscious and to spend more on organic and natural products for their families’ health and well-being. However, if customer demand for such products does not achieve the levels we expect, whether due to slowing economic conditions, changing consumer tastes or otherwise, the results of operations and growth of our Consumer Health business could be materially and adversely affected.

146

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of operating results and financial condition are based upon our consolidated financial statements. The preparation of consolidated financial statements requires us to estimate the effect of various matters that are inherently uncertain as of the date of the consolidated financial statements. Each of these required estimates varies with regard to the level of judgment involved and its potential impact on our reported financial results. Estimates are deemed critical when a different estimate could have reasonably been used or where changes in the estimates are reasonably likely to occur from period to period, and a different estimate would materially impact our financial position, changes in financial position or results of operations. Our significant accounting policies are discussed under note 3 to our consolidated financial statements included in this annual report. We believe the following critical accounting policies are affected by significant judgments and estimates used in the preparation of our consolidated financial statements and that the judgments and estimates are reasonable.

Revenue recognition—Innovation Platform

Our Innovation Platform reportable segment principally generates revenue from license and collaboration contracts. The license and collaboration contracts generally contain multiple performance obligations including (1) the license to the commercialization rights of a drug compound and (2) the research and development services for each specified treatment indication, which are accounted for separately if they are distinct, i.e. if a product or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer.

The transaction price generally includes fixed and variable consideration in the form of upfront payment, research and development cost reimbursements, contingent milestone payments and sales-based royalties. Contingent milestone payments are not included in the transaction price until it becomes probable that a significant reversal of revenue will not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation is based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. We estimate the standalone selling prices based on the income approach.

Control of the license to the drug compounds transfers at the inception date of the collaboration agreements and consequently, amounts allocated to this performance obligation are generally recognized at a point in time. Conversely, research and development services for each specified indication are performed over time and amounts allocated to these performance obligations are generally recognized over time using cost inputs as a measure of progress. We have determined that research and development expenses provide an appropriate depiction of measure of progress for the research and development services. Changes to estimated cost inputs may result in a cumulative catch-up adjustment.

Revenue recognition from sales of drug products developed from the Innovation Platform follows revenue recognition from sales of goods in the Commercial Platform below.

Revenue recognition—Commercial Platform

Our Commercial Platform reportable segment principally generates revenue from (1) sales of goods, which are the manufacture or purchase and distribution of products including drug products developed from the Innovation Platform and other consumer health products, (2) royalty revenues from license and collaboration contracts and (3) sales of services, which are the provision of sales, distribution and marketing services to pharmaceutical manufacturers. We evaluate whether we are the principal or agent for these contracts, which include prescription drug products and consumer health products. Where we obtain control of the goods for distribution, we are the principal (i.e. recognizes sales of goods on a gross basis). Where we do not obtain control of the goods for distribution, we are the agent (i.e. recognizes provision of services on a net basis). Control is primarily evidenced by taking physical possession and inventory risk of the goods.

Revenue from sales of goods is recognized when the customer takes possession of the goods. We have determined that this occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point of sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Royalty revenues are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

147

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, we recognize revenue from provision of services based on amounts that can be invoiced to the customer.

Share-based Compensation

We recognize share-based compensation expense on share options granted to employees and directors based on their estimated grant date fair value using the polynomial model. Determining the fair value of share options requires the use of highly subjective assumptions. This polynomial pricing model uses various inputs to measure fair value, including estimated market value of our underlying ordinary shares at the grant date, contractual terms, estimated volatility, risk-free interest rate and expected dividend yields. The assumptions in determining the fair value of share options are highly subjective and represent our best estimates, which involve inherent uncertainties and the application of judgment. As a result, if factors change and different assumptions are used, our level of share-based compensation could be materially different in the future.

We recognize share-based compensation expense in the consolidated statements of operations on a graded vesting basis over the requisite service period, and account for forfeitures as they occur.

Impairment of Long-lived Assets

We evaluate the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets.

We evaluate long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Factors that we consider in deciding when to perform an impairment review include significant under-performance of a business or product line in relation to expectations, significant negative industry or economic trends, and significant changes or planned changes in our use of the assets.

If such indicators exist, the first step of the impairment test is performed to assess if the carrying value of the net assets exceeds the undiscounted cash flows of the assets. If yes, the second step of the impairment test is performed in order to determine if the carrying value of the net assets exceeds the fair value. If yes, impairment is recognized for the excess.

Impairment of Goodwill

Goodwill represents the excess of the purchase price plus fair value of non-controlling interests over the fair value of identifiable assets and liabilities acquired. Goodwill is not amortized, but is tested for impairment at the reporting unit level on at least an annual basis or when an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When performing an evaluation of goodwill impairment, we have the option to first assess qualitative factors, such as significant events and changes to expectations and activities that may have occurred since the last impairment evaluation, to determine if it is more likely than not that goodwill might be impaired.

If as a result of the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the quantitative fair value test is performed to determine if the fair value of the reporting unit exceeds its carrying value. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

Our quantitative fair value test uses the income method to estimate a reporting unit's fair value. The income method is based on a discounted future cash flow approach that uses the following assumptions and inputs: revenue, based on assumed growth rates; costs; and discount rates based on a reporting unit's weighted average cost of capital as determined by considering the observable weighted average cost of capital of comparable companies. Our estimates of revenue growth and costs are based on historical data, various internal estimates, and a variety of external sources. These estimates are developed as part of our routine planning process. We test the reasonableness of the inputs and outcomes of our discounted cash flow analysis against available comparable market data. A reporting unit's carrying value represents the assignment of various assets and liabilities, excluding certain assets and liabilities, such as cash and cash equivalents, short-term investments, and debt. We performed the goodwill impairment test and determined that the fair values of the reporting units exceeded their carrying values and considered that impairment was not necessary for any reporting unit.

148

Impairment of Equity Method investments

Our equity method investments represent our investments in our non-consolidated joint ventures. All of these are in non-marketable equity investments. Non-marketable equity investments are inherently risky, and their success depends on their ability to generate revenues, remain profitable, operate efficiently and raise additional funds and other key business factors. The companies could fail or not be able to raise additional funds when needed, or they may receive lower valuations with less favorable investment terms. These events could cause our investments to become impaired. In addition, financial market volatility could negatively affect our ability to realize value in our investments through liquidity events such as initial public offerings, mergers, and private sales.

We consider if our equity method investments are impaired when events or circumstances suggest that their carrying amounts may not be recoverable. An impairment charge would be recognized in earnings for a decline in value that is determined to be other-than-temporary. This is based on our quantitative and qualitative analysis, which includes assessing the severity and duration of the impairment and the likelihood of recovery before disposal. The investments are recorded at fair value only if impairment is recognized. The recognition of impairment and measurement of fair value requires significant judgment and includes a qualitative and quantitative analysis of events or circumstances that impact the fair value of the investment. Qualitative analysis of our investments involves understanding our investee's revenue and earnings trends relative to pre-defined milestones and overall business prospects, the technological feasibility of our investee's products and technologies, the general market conditions in the investee's industry or geographic area including adverse regulatory or economic changes, and the management and governance structure of the investee. We performed the qualitative and quantitative analysis and determined that events or circumstances did not suggest that the carrying amount of each of our equity method investments may not be recoverable and that impairment was not necessary.

Key Components of Results of Operations

Revenue

We derive our consolidated revenue primarily from (i) licensing and collaboration projects conducted by our Innovation Platform, which generates revenue in the form of upfront payments, milestone payments, payments received for providing research and development services for our collaboration projects, as well as sales of services to related parties; (ii) royalties on sales of Elunate; and (iii) the sales of goods and services by our Commercial Platform, which generates revenue from the distribution and marketing of prescription pharmaceutical products by our Prescription Drugs business and consumer health products by our Consumer Health business.

149

The following table sets forth the components of our consolidated revenue for the years indicated, which does not include the revenue from our Commercial Platform’s non-consolidated joint ventures, Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan. Our revenue from research and development projects for related parties is attributable to income for research and development services that we received primarily from Shanghai Hutchison Pharmaceuticals and Nutrition Science Partners, our former non-consolidated joint venture with Nestlé Health Science. Our revenue from sales to related parties is attributable to sales by our Commercial Platform to indirect subsidiaries of CK Hutchison.

Our Prescription Drugs business’s revenue primarily comprises revenue from the commercial services, logistics and distribution business of our consolidated Hutchison Sinopharm joint venture with Sinopharm, a leading distributor of pharmaceutical and healthcare products and a leading supply chain service provider in China. Additionally, in November 2018, we launched commercial sales of Elunate in China. The revenue we generate from Elunate is comprised of royalty revenue and revenue from the sales of Elunate to Eli Lilly which we manufacture and sell at cost. For the year ended December 31, 2019, we generated $10.8 million, of which $2.7 million was royalty revenue and $8.1 million was revenue from sales to Eli Lilly.

150

Hutchison Sinopharm was historically a distributor of AstraZeneca’s quetiapine tablets (under the Seroquel trademark). Under this arrangement, Hutchison Sinopharm managed the distribution and logistics for this drug and Shanghai Hutchison Pharmaceuticals marketed it. Our consolidated revenues originally reflected total gross sales of Seroquel. This began to shift, however, to a fee-for-service model in October 2017 when China started implementing a new regulatory two-invoice system. See Item 4.B “Business Overview—Regulation—Government Regulation of Pharmaceutical Product Development and Approval—PRC Regulation of Pharmaceutical Product Development and Approval—Distribution of Pharmaceutical Products.” In May 2019, our distribution of Seroquel terminated, and Shanghai Hutchison Pharmaceuticals’ medical sales team previously supporting the commercialization of Seroquel are now supporting the sales and marketing of other products.

The revenue of our Prescription Drugs business’s non-consolidated joint venture, Shanghai Hutchison Pharmaceuticals, the accounts of which are prepared in accordance with IFRS as issued by the IASB and whose revenue is not included in our consolidated revenue, was $244.6 million, $275.7 million and $272.1 million for the years ended December 31, 2017, 2018 and 2019, respectively. Shanghai Hutchison Pharmaceuticals is a joint venture with Shanghai Pharmaceuticals, a leading pharmaceuticals company in China, and primarily focuses on the manufacture and sale of prescription pharmaceutical products in China. We and Shanghai Pharmaceuticals each own 50% of this joint venture. We have the right to nominate the general manager and other management of this joint venture and run its day-to-day operations. The effect of Shanghai Hutchison Pharmaceuticals on our consolidated financial results is discussed below under “—Equity in Earnings of Equity Investees.”

Our Consumer Health business’s revenue primarily comprises revenue from sales of organic and natural products by Hutchison Hain Organic, our 50% consolidated joint venture with Hain Celestial, a Nasdaq-listed, natural and organic food and personal care products company. We consolidate the results of this joint venture into our results of operations as we own 50% of its equity and hold an additional casting vote in the event of a deadlock. Our Consumer Health business’s revenue is also comprised of revenue from sales of Zhi Ling Tong infant nutrition and other health supplement products manufactured by Hutchison Healthcare, our wholly owned subsidiary, and distributed through Hutchison Sinopharm, and certain third-party consumer products distributed and marketed by Hutchison Consumer Products, a wholly owned subsidiary.

The revenue of our Consumer Health business’s non-consolidated joint venture, Hutchison Baiyunshan, the accounts of which are prepared in accordance with IFRS as issued by the IASB and whose revenue is not included in our consolidated revenue, was $227.4 million, $215.8 million and $215.4 million for the years ended December 31, 2017, 2018 and 2019, respectively. Hutchison Baiyunshan is a joint venture with Guangzhou Baiyunshan, a leading China-based pharmaceutical company, and primarily focuses on the manufacture and distribution of over-the-counter pharmaceutical products in China. Our interest in Hutchison Baiyunshan is held through an 80%-owned subsidiary of ours, Hutchison BYS (Guangzhou) Holding Limited, which owns 50% of that joint venture, with the other 50% interest held by Guangzhou Baiyunshan. The effect of Hutchison Baiyunshan on our consolidated financial results is discussed under “—Equity in Earnings of Equity Investees.”

In addition to the research and development costs shown above, the table below summarizes the research and development costs and impairment provision incurred by our former non-consolidated Nutrition Science Partners joint venture, primarily in relation to the development of our drug candidate HMPL-004/HM004-6599. The losses incurred by this joint venture during the periods indicated were reflected on our consolidated statements of operations in the equity in earnings of equity investees line item. Nutrition Science Partners did not have any operating activities for the year ended December 31, 2019. On December 9, 2019, we acquired the remaining 50% shareholding in Nutrition Science Partners from our joint venture partner for approximately $8.1 million, representing the cash balance at that time; and, therefore, Nutrition Science Partners will be included in our consolidated group in future periods. The consolidated financial statements of Nutrition Science Partners are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report. For more information on this joint venture, see “—Equity in Earnings of Equity Investees.”

We cannot determine with certainty the duration and completion costs of the current or future pre-clinical or clinical studies of our drug candidates or if, when, or to what extent we will generate revenues from the commercialization and sale of any of our drug candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our drug candidates. The duration, costs, and timing of clinical studies and development of our drug candidates will depend on a variety of factors, including:

● the scope, rate of progress and expense of our ongoing as well as any additional clinical studies and other research and development activities;

● future clinical study results;

● uncertainties in clinical study enrollment rate;

● significant and changing government regulation; and

● the timing and receipt of any regulatory approvals.

A change in the outcome of any of these variables with respect to the development of a drug candidate could mean a significant change in the costs and timing associated with the development of that drug candidate.

For more information on the risks associated with the development of our drug candidates, see Item 3.D. “Risk Factors—Risks Relating to Our Innovation Platform and Development of Our Drug Candidates—All of our drug candidates, other than fruquintinib for one indication in China, are still in development. If we are unable to obtain regulatory approval and ultimately commercialize our drug candidates, or if we experience significant delays in doing so, our business will be materially harmed.”

Equity in Earnings of Equity Investees

We have historically derived a significant portion of our net income from our equity in earnings of equity investees, which was primarily attributable to two of our Commercial Platform’s non-consolidated joint ventures, Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan, partially offset by losses at our Innovation Platform’s former non-consolidated joint venture, Nutrition Science Partners. Our equity in earnings of equity investees (net of tax) contributed by the non-consolidated joint ventures from our Commercial Platform, Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan, was $38.2 million, $38.3 million and $40.6 million for the years ended December 31, 2017, 2018 and 2019, respectively. Equity in earnings of Shanghai Hutchison Pharmaceuticals in the year ended December 31, 2017 included one-time gains of $2.5 million, net of tax, from government subsidies paid to Shanghai Hutchison Pharmaceuticals by the Shanghai government.

154

Our equity in earnings of equity investees (net of tax) contributed by our Innovation Platform was losses of $4.5 million, $19.0 million and income of $0.1 million for the years ended December 31, 2017, 2018 and 2019, respectively. The losses in prior years were primarily attributable to losses at Nutrition Science Partners, which has historically incurred significant losses attributable to research and development expenses, the cost of clinical trials for the drug candidate HMPL-004/HM004-6599 and the full impairment provision of its $30.0 million intangible asset in the year ended December 31, 2018 of which our attributable portion was $15.0 million. On December 9, 2019, we acquired our joint venture partner’s 50% shareholding in Nutrition Science Partners, after which Nutrition Science Partners became our consolidated subsidiary.

Revenue of Shanghai Hutchison Pharmaceuticals and Hutchison Baiyunshan are mainly affected by the sales volume and pricing of their prescription and over-the-counter pharmaceutical products.

The following table shows the revenue of these two Commercial Platform non-consolidated joint ventures for the years indicated. Nutrition Science Partners did not have revenue for any of the years presented. The consolidated financial statements of these joint ventures are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report.

Taxation

Cayman Islands

Hutchison China MediTech Limited is incorporated in the Cayman Islands. The Cayman Islands currently levies no taxes on profits, income, gains or appreciation earned by individuals or corporations. In addition, our payment of dividends, if any, is not subject to withholding tax in the Cayman Islands. For more information, see Item 10.E. “Taxation—Overview of Tax Implications of Various Other Jurisdictions—Cayman Islands Taxation.”

People’s Republic of China

Our subsidiaries and joint ventures incorporated in the PRC are governed by the EIT Law and regulations. Under the EIT Law, the standard EIT rate is 25% on taxable profits as reduced by available tax losses. Tax losses may be carried forward to offset any taxable profits for the following five years (ten years for those with HNTE status, with effective from 1 January 2018). Our subsidiary, Hutchison MediPharma, was granted Technology Advanced Service Enterprise status from January 1, 2010 to December 31, 2018, and has been successful in its application to renew its HNTE status from January 1, 2017 to December 31, 2019. Our non-consolidated joint ventures, Hutchison Baiyunshan and Shanghai Hutchison Pharmaceuticals, have been successful in their respective applications to renew their HNTE status from January 1, 2017 to December 31, 2019. Accordingly, these entities were subject to a preferential EIT rate of 15% for the years ended December 31, 2017, 2018 and 2019. Hutchison MediPharma (Suzhou) Limited, a wholly owned subsidiary of Hutchison MediPharma, has been successful in its application for the HNTE status in 2018 which will last three years from January 1, 2018 to December 31, 2020.

For more information, see Item 10.E. “Taxation—Taxation in the PRC.” Please also see Item. 3 “Key Information—Risk Factors—Other Risks and Risks Relating to Doing Business in China—Our business benefits from certain PRC government tax incentives. The expiration of, changes to, or our PRC subsidiaries/joint ventures failing to continuously meet the criteria for these incentives could have a material adverse effect on our operating results by significantly increasing our tax expenses.”

156

Hong Kong

Hutchison China MediTech Limited and certain of its subsidiaries are subject to Hong Kong Profits Tax laws and regulations. In March 2018, the Hong Kong two-tiered Profits Tax rates regime was signed into law under which the first HK$2.0 million ($0.3 million) of assessable profits of qualifying corporations will be taxed at 8.25%, with the remaining assessable profits taxed at 16.5%. Hong Kong Profits Tax has been provided for at the relevant rates on the estimated assessable profits less estimated available tax losses, if any, of these entities as applicable.

According to the EIT Law, dividends declared after January 1, 2008 and paid by PRC foreign-invested enterprises to their non-PRC parent companies will be subject to PRC withholding tax at 10% unless there is a tax treaty between the PRC and the jurisdiction in which the overseas parent company is a tax resident and which specifically exempts or reduces such withholding tax, and such tax exemption or reduction is approved by the relevant PRC tax authorities. Pursuant to the Arrangement, if the shareholder of the PRC enterprise is a Hong Kong tax resident and directly holds a 25% or more equity interest in the PRC enterprise and is considered to be the beneficial owner of dividends paid by the PRC enterprise, such withholding tax rate may be lowered to 5%, subject to approvals by the relevant PRC tax authorities. For more information, see Item 10.E. “Taxation—Taxation in the PRC” and “Taxation—Overview of Tax Implications of Various Other Jurisdictions—Hong Kong Taxation.”

Year Ended December 31, 2019 Compared to Year Ended December 31, 2018

Revenues

Our revenue decreased by 4.3% from $214.1 million for the year ended December 31, 2018 to $204.9 million for the year ended December 31, 2019, resulting from decreased revenue from our Innovation Platform.

Revenue from our Innovation Platform decreased by 57.4% from $37.6 million for the year ended December 31, 2018 to $16.0 million for the year ended December 31, 2019. The decrease was primarily due to the fact that the prior period included the milestone payment of $13.5 million that we received from Eli Lilly following the approval in September 2018 of Elunate in China for the treatment of metastatic colorectal cancer. The decrease was also due to a $7.0 million reduction in service fees from Nutrition Science Partners.

Revenue from our Commercial Platform increased by 7.0% from $176.5 million for the year ended December 31, 2018 to $188.9 million for the year ended December 31, 2019. The increase was primarily due to an increase in revenue from our Prescription Drugs business. Revenue from our Prescription Drugs business increased by 13.2% from $136.4 million for the year ended December 31, 2018 to $154.5 million for year ended December 31, 2019 primarily due to increased sales by our consolidated joint venture Hutchison Sinopharm, despite the depreciation of the renminbi against the U.S. dollar by approximately 5% between the periods (using the weighted average monthly exchange rate for the periods). The increase was also due to the $7.2 million increase in sales and royalties from the commercial sale of Elunate for the year ended December 31, 2019. Such growth was partially offset by a decrease in Seroquel revenues of $21.9 million after the discontinuation of our distribution of Seroquel in May 2019 due to the purported termination by Luye Pharma Hong Kong Ltd. of our Seroquel distribution agreement with them. See Item 4.B. “Business Overview—Our Commercial Platform—Prescription Drug Business—Hutchison Sinopharm” for further details regarding the current status of our Seroquel marketing and distribution rights.

Revenue from our Consumer Health business decreased by 14.1% from $40.1 million for the year ended December 31, 2018 to $34.4 million for the year ended December 31, 2019, which was primarily attributable to decreased sales of consumer products in Hong Kong.

Our Commercial Platform’s results of operations are affected by seasonality. For more information, see “—Factors Affecting our Results of Operations—Commercial Platform—Seasonality.”

157

Cost of Sales

Our cost of sales increased by 11.3% from $143.9 million for the year ended December 31, 2018 to $160.2 million for the year ended December 31, 2019. This increase was primarily due to higher costs of goods of $23.0 million due to increased sales by our Commercial Platform businesses, offset in part by a decrease in costs of services of $6.7 million due to the aforementioned discontinuation of our distribution of Seroquel. Our cost of sales increased at a higher rate than revenue from our Commercial Platform due to a decreased proportion of sales of higher margin products and services including Seroquel in 2019 compared to 2018. As a result, cost of sales as a percentage of our revenue from our Commercial Platform increased from 81.6% to 84.8% across these periods.

Research and Development Expenses

Our research and development expenses increased by 21.0% from $114.2 million for the year ended December 31, 2018 to $138.2 million for the year ended December 31, 2019, which was primarily attributable to a $14.1 million increase in payments to CROs and other clinical trial related costs and a $10.9 million increase in employee compensation related costs. These increased costs incurred by our Innovation Platform were due to a significant expansion of clinical activities and rapid organizational growth to support such expansion. In particular, this increase was attributable to the expansion of the savolitinib, fruquintinib, surufatinib, HMPL-523 and HMPL-689 development programs. As a result, research and development expenses as a percentage of our revenue increased from 53.3% to 67.4% across these periods.

Selling Expenses

Our selling expenses decreased by 22.6% from $17.7 million for the year ended December 31, 2018 to $13.7 million for the year ended December 31, 2019. This decrease was primarily due to the aforementioned discontinuation of our distribution of Seroquel. Selling expenses as a percentage of our revenue from our Commercial Platform decreased from 10.1% to 7.3% across these periods.

Administrative Expenses

Our administrative expenses increased by 26.9% from $30.9 million for the year ended December 31, 2018 to $39.2 million for the year ended December 31, 2019. This was primarily due to a $5.0 million increase in administrative expenses incurred by our corporate head office for the organizational expansion and increased professional fees associated with equity capital market transactions. There was also an increase of $2.5 million in administrative expenses incurred by our Innovation Platform, which was mainly for increased staff costs to support the expansion of our clinical activities. Administrative expenses as a percentage of our revenue increased from 14.4% to 19.1% across these periods.

Other Income

We had net other income of $6.0 million for the year ended December 31, 2018, compared to net other income of $5.3 million for the year ended December 31, 2019. The decrease was primarily due to a decline in interest income of $1.0 million from lower amounts of cash, cash equivalents and short-term investments.

Income Tax Expense

Our income tax expense decreased by 17.4% from $4.0 million for the year ended December 31, 2018 to $3.3 million for the year ended December 31, 2019 primarily due to a lower level of taxable income generated by our Commercial Platform subsidiaries.

Equity in Earnings of Equity Investees

Our equity in earnings of equity investees, net of tax, increased by 110.5% from $19.3 million for the year ended December 31, 2018 to $40.7 million for the year ended December 31, 2019. This change was primarily due to the fact that Nutrition Science Partners had no operating activity in 2019 and the prior period included the full impairment provision of Nutrition Science Partners’ intangible assets of which our attributable portion was $15.0 million.

158

Shanghai Hutchison Pharmaceuticals

The following table shows a summary of the results of operations of Shanghai Hutchison Pharmaceuticals for the years indicated. The consolidated financial statements of Shanghai Hutchison Pharmaceuticals are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report.

Equity in earnings of equity investee attributable to our company	30,654	11.3	29,884	10.8

Shanghai Hutchison Pharmaceuticals’ revenue decreased by 1.3% from $275.7 million for the year ended December 31, 2018 to $272.1 million for the year ended December 31, 2019, which was primarily due to the depreciation of the renminbi against the U.S. dollar by approximately 4% between the periods (using the weighted average monthly exchange rate for the periods). Additionally, distribution business sales and service revenue decreased by 52.0% from $23.1 million for the year ended December 31, 2018 to $11.1 million for the year ended December 31, 2019, primarily due to the lower provision of services from the aforementioned discontinuation of our distribution of Seroquel. The decrease was offset by an increase in sales of She Xiang Bao Xin pills, a vasodilator used in the treatment of heart conditions. Sales of She Xiang Bao Xin pills increased by 2.7% from $233.1 million for the year ended December 31, 2018 to $239.5 million for the year ended December 31, 2019, primarily due to continued geographical expansion of sales coverage.

Cost of sales decreased by 6.5% from $82.7 million for the year ended December 31, 2018 to $77.3 million for the year ended December 31, 2019, primarily due to decreased cost of goods sold as a result of decreased distribution business sales and service revenue.

Selling expenses during these periods decreased by 1.2% from $112.0 million for the year ended December 31, 2018 to $110.6 million for the year ended December 31, 2019 in line with the decrease in sales.

Administrative expenses increased by 1.6% from $14.5 million for the year ended December 31, 2018 to $14.8 million for the year ended December 31, 2019 due to an increase in general overhead costs incurred.

Taxation charge increased by 17.5% from $9.3 million for the year ended December 31, 2018 to $11.0 million for the year ended December 31, 2019. This was primarily due to the recognition of $0.7 million deferred tax assets on temporary differences in the year ended December 31, 2018, arising from advertising and promotion expenditures incurred prior to 2018.

As a result of the foregoing, profit increased by 2.6% from $59.8 million for the year ended December 31, 2018 to $61.3 million for the year ended December 31, 2019. Our equity in earnings of equity investees contributed by this joint venture was $29.9 million and $30.7 million for the years ended December 31, 2018 and 2019, respectively.

Hutchison Baiyunshan

The following table shows a summary of the results of operations of Hutchison Baiyunshan for the years indicated. The consolidated financial statements of Hutchison Baiyunshan are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report.

Equity in earnings of equity investee attributable to our company	9,899	4.6	8,430	3.9

Hutchison Baiyunshan’s revenue decreased slightly from $215.8 million for the year ended December 31, 2018 to $215.4 million for the year ended December 31, 2019 due to a decrease in sales of Fu Fang Dan Shen due to heightened competitive activity, offset by the increase of sales of Hutchison Baiyunshan’s other products.

Cost of sales decreased by 2.4% from $102.7 million for the year ended December 31, 2018 to $100.3 million for the year ended December 31, 2019 due to the decrease in sales.

Selling expenses increased by 5.0% from $70.5 million for the year ended December 31, 2018 to $74.0 million for the year ended December 31, 2019 due to Hutchison Baiyunshan managing more marketing activities directly for its distributors in order to promote broader awareness and consistent messaging for Hutchison Baiyunshan’s products.

Administrative expenses decreased by 8.4% from $26.0 million for the year ended December 31, 2018 to $23.8 million for the year ended December 31, 2019 due to a decrease in general overhead costs incurred.

Taxation charge decreased by 14.0% from $4.2 million for the year ended December 31, 2018 to $3.6 million for the year ended December 31, 2019. This decline is primarily due to the reversal of deferred tax assets previously recognized of $0.7 million for the year ended December 31, 2018 based on the likelihood of such asset being utilized in the near future.

As a result of the foregoing, profit attributable to equity holders of Hutchison Baiyunshan increased by 17.4% from $16.9 million for the year ended December 31, 2018 to $19.8 million for the year ended December 31, 2019. Our equity in earnings of equity investees contributed by this joint venture was $8.4 million and $9.9 million for the years ended December 31, 2018 and 2019, respectively.

Nutrition Science Partners

The following table shows a summary of the results of operations of Nutrition Science Partners for the period/year indicated. The consolidated financial statements of Nutrition Science Partners are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report.

	Period Ended December 9,		Year Ended December 31,
	2019		2018
	($’000)	%	($’000)	%
Revenue	—	—	—	—
Profit/(loss) for the period/year	199	100.0	(38,198)	100.0
Equity in earnings of equity investee attributable to our company	100	50.0	(19,099)	50.0

Nutrition Science Partners had a loss of $38.2 million for the year ended December 31, 2018, compared to profit of $0.2 million for the period ended December 9, 2019. Nutrition Science Partners had no revenue during these years. The change was primarily due to the fact that Nutrition Science Partners had no operating activity in 2019 and the prior period included the full impairment provision of Nutrition Science Partners’ intangible assets of which our attributable portion was $15.0 million. Our equity in earnings of equity investees contributed by this joint venture was a loss of $19.1 million for the year ended December 31, 2018, compared to income of $0.1 million for the period ended December 9, 2019.

Net Loss

As a result of the foregoing, our net loss increased from $71.3 million for the year ended December 31, 2018 to $103.7 million for the year ended December 31, 2019. Net loss attributable to our company increased from $74.8 million for the year ended December 31, 2018 to $106.0 million for the year ended December 31, 2019.

Segment Operating Loss

Our segment operating loss increased from $66.3 million for the year ended December 31, 2018 to $99.4 million for the year ended December 31, 2019 which was primarily due to an increase in the operating loss of our Innovation Platform from $104.6 million for the year ended December 31, 2018 to $133.3 million for the year ended December 31, 2019. The increase in the operating loss of our Innovation Platform across these periods was primarily due to a significant expansion of our clinical activities and an increase in the number of staff and other organizational growth to support such expansion.

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017

Revenues

Our revenue decreased by 11.2% from $241.2 million for the year ended December 31, 2017 to $214.1 million for the year ended December 31, 2018, resulting from decreased revenue from our Commercial Platform.

Revenue from our Commercial Platform decreased by 14.0% from $205.2 million for the year ended December 31, 2017 to $176.5 million for the year ended December 31, 2018, primarily due to a decrease in revenue from our Prescription Drugs business. Revenue from our Prescription Drugs business decreased by 18.0% from $166.4 million for the year ended December 31, 2017 to $136.4 million for year ended December 31, 2018, primarily due to the implementation of the two-invoice system in China since October 2017. As a result, we started recording the service fees we earn from the distribution of certain third-party drugs instead of recording the gross sales of such products as we had done previously. The impact was offset by the $3.6 million increase in sales and royalties revenue of Elunate following its commercial launch at the end of 2018. Revenue from our Consumer Health business increased by 3.3% from $38.8 million for the year ended December 31, 2017 to $40.1 million for the year ended December 31, 2018, which was primarily attributable to increased sales of the Zhi Ling Tong infant nutrition and other health supplement products.

Revenue from our Innovation Platform increased by 4.6% from $36.0 million for the year ended December 31, 2017 to $37.6 million for the year ended December 31, 2018. The increase was attributable to a higher level of milestone payments that we received from our collaboration partners, including the milestone payment of $13.5 million that we received from Eli Lilly following the approval in September 2018 of fruquintinib for drug registration in China for the treatment of metastatic colorectal cancer patients.

Our Commercial Platform’s results of operations are affected by seasonality. For more information, see “—Factors Affecting our Results of Operations—Commercial Platform—Seasonality.”

Cost of Sales

Our costs of sales decreased by 18.1% from $175.8 million for the year ended December 31, 2017 to $143.9 million for the year ended December 31, 2018. This decrease was in line with the decrease in our Commercial Platform revenue across these periods. Costs of sales as a percentage of our revenue from our Commercial Platform decreased from 85.7% to 81.6% across these periods due to the change to recording more services fees and to selling fewer lower margin third-party drugs.

Research and Development Expenses

Our research and development expenses increased by 51.2% from $75.5 million for the year ended December 31, 2017 to $114.2 million for the year ended December 31, 2018, which was primarily attributable to a $28.4 million increase in payments to CROs and other clinical trial related costs and a $10.5 million increase in employee compensation related costs. These increased costs incurred by our Innovation Platform were due to a significant expansion of clinical activities and rapid organizational growth to support such expansion. In particular, this increase was attributable to the expansion of the surufatinib, HMPL-523 and fruquintinib development programs. As a result, research and development expenses as a percentage of our revenue increased from 31.3% to 53.3% across these periods.

161

Selling Expenses

Our selling expenses decreased by 8.2% from $19.3 million for the year ended December 31, 2017 to $17.7 million for the year ended December 31, 2018. This decrease was primarily driven by a $3.0 million decrease in selling expenses under our Prescription Drugs business as the implementation of the two-invoice system caused us to start recording the costs associated with the service fees we earn from the distribution of certain third-party drugs as costs of sales instead of selling expenses as we had done previously. Selling expenses as a percentage of our revenue from our Commercial Platform increased slightly from 9.4% to 10.1% across these periods primarily due to the decrease in our Commercial Platform revenue.

Administrative Expenses

Our administrative expenses increased by 29.0% from $24.0 million for the year ended December 31, 2017 to $30.9 million for the year ended December 31, 2018. This increase was primarily due to a $3.0 million increase in administrative expenses incurred by our Innovation Platform, which mainly related to the increased staff cost to support the rapid expansion of our clinical activities and increased office expenses as we started to rent a new research and development facility in Shanghai in early 2018. Administrative expenses as a percentage of our revenue increased from 9.9% to 14.4% across these periods.

Other Income/Expenses

We had other expenses of $0.1 million for the year ended December 31, 2017, compared to other income of $6.0 million for the year ended December 31, 2018, primarily due to a higher level of interest income earned from the proceeds received from our follow-on offering in October 2017, which increased from $1.2 million for the year ended December 31, 2017 to $6.0 million for the year ended December 31, 2018. In addition, the increase in other income also resulted from the receipt of a new government grant by Hutchison Sinopharm as well as higher payments to us by the depositary bank which administers our ADS program in the year ended December 31, 2018 due to a higher number of our ADSs issued and eligible for compensation under the program.

Our interest expense decreased from $1.5 million for the year ended December 31, 2017 to $1.0 million for the year ended December 31, 2018, primarily due to a decrease in the guarantee fee payments on bank loans from $0.3 million in the year ended December 31, 2017 to nil in the year ended December 31, 2018.

Income Tax Expense

Our income tax expense increased by 28.7% from $3.1 million for the year ended December 31, 2017 to $4.0 million for the year ended December 31, 2018 primarily due to a higher level of taxable income from our Commercial Platform.

Equity in Earnings of Equity Investees

Our equity in earnings of equity investees, net of tax, decreased by 42.6% from $33.7 million for the year ended December 31, 2017 to $19.3 million for the year ended December 31, 2018. This decrease was primarily due to an increase in net loss at Nutrition Science Partners, our Innovation Platform’s non-consolidated joint venture.

The consolidated financial statements of Shanghai Hutchison Pharmaceuticals are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report.

Equity in earnings of equity investee attributable to our company	29,884	10.8	27,812	11.4

Shanghai Hutchison Pharmaceuticals’ revenue increased by 12.7% from $244.6 million for the year ended December 31, 2017 to $275.7 million for the year ended December 31, 2018, which was primarily due to increased sales of She Xiang Bao Xin pills, a vasodilator used in the treatment of heart conditions. Sales of She Xiang Bao Xin pills grew by 11.4% from $209.2 million for the year ended December 31, 2017 to $233.1 million for the year ended December 31, 2018, primarily due to continued price increases and geographical expansion of sales coverage. Additionally, distribution business sales and service revenue increased by 27.6% from $18.1 million for the year ended December 31, 2017 to $23.1 million for the year ended December 31, 2018, primarily due to the higher provision of services from increased sales of Seroquel.

Cost of sales increased by 20.6% from $68.6 million for the year ended December 31, 2017 to $82.7 million for the year ended December 31, 2018, primarily due to increased cost of goods sold as a result of increased sales of She Xiang Bao Xin pills and distribution business sales and service revenue.

Selling expenses during these periods increased by 7.2% from $104.5 million for the year ended December 31, 2017 to $112.0 million for the year ended December 31, 2018 as a result of increased spending on marketing and promotional activities to support the increase in sales.

Administrative expenses increased by 9.5% from $13.3 million for the year ended December 31, 2017 to $14.5 million for the year ended December 31, 2018 due to an increase in general overhead costs incurred.

Taxation charge decreased by 13.8% from $10.9 million for the year ended December 31, 2017 to $9.3 million for the year ended December 31, 2018, which was due to lower taxable profit primarily resulting from an increase of tax deductible research and development expenses of $0.4 million as well as the recognition of $0.7 million deferred tax assets on temporary differences arising from advertising and promotion expenditures incurred prior to 2018.

As a result of the foregoing, profit increased by 7.5% from $55.6 million for the year ended December 31, 2017 to $59.8 million for the year ended December 31, 2018. Our equity in earnings of equity investees contributed by this joint venture was $27.8 million and $29.9 million for the years ended December 31, 2017 and 2018, respectively.

Hutchison Baiyunshan

The following table shows a summary of the results of operations of Hutchison Baiyunshan for the years indicated. The consolidated financial statements of Hutchison Baiyunshan are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report.

	2018		2017
	($’000)	%	($’000)	%
Revenue	215,838	100.0	227,422	100.0
Cost of sales	(102,701)	(47.6)	(135,964)	(59.8)

Equity in earnings of equity investee attributable to our company	8,430	3.9	10,388	4.6

Hutchison Baiyunshan’s revenue decreased by 5.1% from $227.4 million for the year ended December 31, 2017 to $215.8 million for the year ended December 31, 2018 due to the divestment of one of its subsidiaries in September 2017, which was partially offset by a moderate to severe flu season and the elimination of manufacturing capacity constraints which increased sales of certain of its drug products in 2018.

Cost of sales decreased by 24.5% from $136.0 million for the year ended December 31, 2017 to $102.7 million for the year ended December 31, 2018, primarily due to the divestment of one of its subsidiaries in September 2017.

Selling expenses during these periods increased by 55.8% from $45.3 million for the year ended December 31, 2017 to $70.5 million for the year ended December 31, 2018 due to Hutchison Baiyunshan directly managing more marketing activities for its distributors in order to promote broader awareness and consistent messaging for Hutchison Baiyunshan’s products.

Administrative expenses increased by 5.9% from $24.5 million for the year ended December 31, 2017 to $26.0 million for the year ended December 31, 2018 due to an increase in general overhead costs incurred.

Taxation charge increased by 16.5% from $3.6 million for the year ended December 31, 2017 to $4.2 million for the year ended December 31, 2018 which includes reductions to deferred tax assets of $0.7 million for the year ended December 31, 2018 based on the likelihood of such asset being utilized in the near future.

As a result of the foregoing, profit attributable to equity holders of Hutchison Baiyunshan decreased by 18.8% from $20.8 million for the year ended December 31, 2017 to $16.9 million for the year ended December 31, 2018. Our equity in earnings of equity investees contributed by this joint venture was $10.4 million and $8.4 million for the years ended December 31, 2017 and 2018, respectively.

Nutrition Science Partners

The following table shows a summary of the results of operations of Nutrition Science Partners for the years indicated. The consolidated financial statements of Nutrition Science Partners are prepared in accordance with IFRS as issued by the IASB and are presented separately elsewhere in this annual report.

	Year Ended December 31,

	($’000)	%	($’000)	%
Revenue	—	—	—	—

Equity in earnings of equity investee attributable to our company	(19,099)	50.0	(4,605)	50.0

Nutrition Science Partners had losses of $9.2 million and $38.2 million for the years ended December 31, 2017 and 2018, respectively. Nutrition Science Partners had no revenue during these years. The increase in net loss across these periods was primarily attributable the full impairment provision recorded for its $30.0 million intangible asset related to in-progress research and development projects. Our equity in earnings of equity investees contributed by this joint venture were losses of $4.6 million and $19.1 million for the years ended December 31, 2017 and 2018, respectively.

For more information on the financial results of our non-consolidated joint ventures, see “—Key Components of Results of Operations—Equity in Earnings of Equity Investees.”

Net Loss

As a result of the foregoing, our net loss increased from $23.0 million for the year ended December 31, 2017 to $71.3 million for the year ended December 31, 2018. Net loss attributable to our company increased from $26.7 million for the year ended December 31, 2017 to $74.8 million for the year ended December 31, 2018.

Segment Operating Loss

Our segment operating loss increased from $18.4 million for the year ended December 31, 2017 to $66.3 million for the year ended December 31, 2018, as a result of a significant increase in the operating loss of our Innovation Platform from $52.0 million for the year ended December 31, 2017 to $104.6 million for the year ended December 31, 2018, partially offset by a slight increase in operating profit of our Commercial Platform from $45.1 million for the year ended December 31, 2017 to $49.0 million for the year ended December 31, 2018. The increase in the operating loss of our Innovation Platform across these periods was primarily due to a significant expansion of our clinical activities and an increase in the number of staff and other organizational growth to support such expansion.

B.    Liquidity and Capital Resources.

To date, we have taken a multi-source approach to fund our operations, including through cash flows generated and dividend payments from our Commercial Platform, service and milestone and upfront payments from our Innovation Platform’s collaboration partners, and bank borrowings. Since our founding, we have received various financial support from CK Hutchison in the form of undertakings for bank borrowings, as well as investments from other third parties, proceeds from our listings on the AIM market of the London Stock Exchange in 2006 and the Nasdaq Global Select Market in 2016 and our follow-on offerings in 2017 and 2020.

Our Innovation Platform has historically not generated significant profits or has operated at a net loss, as creating potential global first-in-class or best-in-class drug candidates requires a significant investment of resources over a prolonged period of time. As a result, we anticipate that we may need additional financing for our Innovation Platform in future periods. See Item 3.D. “Risk Factors—Risks Relating to Our Innovation Platform and Development of Our Drug Candidates—Historically, our in house research and development division, known as our Innovation Platform, has not generated significant profits or has operated at a net loss. Our future profitability is dependent on the successful commercialization of our drug candidates.”

165

As of December 31, 2019, we had cash and cash equivalents and short-term investments of $217.2 million and unutilized bank facilities of $119.3 million. Substantially all of our bank deposits are at major financial institutions, which we believe are of high credit quality. As of December 31, 2019, we had $26.8 million in bank loans, all of which was related to a term loan from HSBC. The total weighted average cost of bank borrowings for the year ended December 31, 2019 was 3.30% per annum. For additional information, see “—Loan Facilities.”

Certain of our subsidiaries and non-consolidated joint ventures, including those registered as wholly foreign-owned enterprises in China, are required to set aside at least 10.0% of their after-tax profits to their general reserves until such reserves reach 50.0% of their registered capital. There is no fixed percentage of after-tax profit required to be set aside for the general reserves for our PRC joint ventures. Profit appropriated to the reserve funds for our subsidiaries and non-consolidated joint ventures incorporated in the PRC was approximately $10,000, $15,000 and $51,000 for the years ended December 31, 2017, 2018 and 2019, respectively. In addition, as a result of PRC regulations restricting dividend distributions from such reserve funds and from a company’s registered capital, our PRC subsidiaries are restricted in their ability to transfer a certain amount of their net assets to us as cash dividends, loans or advances. This restricted portion amounted to $0.3 million as of December 31, 2019. Although we do not currently require any such dividends, loans or advances from our PRC subsidiaries to fund our operations, should we require additional sources of liquidity in the future, such restrictions may have a material adverse effect on our liquidity and capital resources. For more information, see Item 4.B. “Business Overview—Regulation—PRC Regulation of Foreign Currency Exchange, Offshore Investment and State-Owned Assets—Regulation on Investment in Foreign invested Enterprises—Regulation on Dividend Distribution.”

In addition, our non-consolidated joint ventures held an aggregate of $62.7 million in cash and cash equivalents and no bank borrowings as of December 31, 2019. These cash and cash equivalents are only accessible by us through dividend payments from these joint ventures. The level of dividends declared by these joint ventures is subject to agreement each year between us and our joint venture partners based on the profitability and working capital needs of the joint ventures. As a result, we cannot guarantee that these joint ventures will continue to pay dividends to us in the future at the same rate we have enjoyed in the past, or at all, which may have a material adverse effect on our liquidity and capital resources. For more information, see Item 3.D. “Risk Factors—Risks Relating to Our Commercial Platform and Sales of Our Commercial-stage Drug Candidates—As a significant portion of our Commercial Platform business, which consists of our Prescription Drugs and Consumer Health divisions, is conducted through joint ventures, we are largely dependent on the success of our joint ventures and our receipt of dividends or other payments from our joint ventures for cash to fund our operations.”

We believe that our current levels of cash and cash equivalents, short-term investments, along with cash flows from operations, dividend payments and unutilized bank borrowings, will be sufficient to meet our anticipated cash needs for at least the next 12 months. However, we may require additional financing in order to fund all of the clinical development efforts at our Innovation Platform that we plan to undertake to accelerate the development of our clinical-stage drug candidates. For more information, see Item 3.D. “Risk Factors—Risks Relating to Our Financial Position and Need for Capital.”

Net Cash used in Operating Activities

Net cash used in operating activities was $32.8 million for the year ended December 31, 2018, compared to net cash used in operating activities of $80.9 million for the year ended December 31, 2019. The net change of $48.1 million was primarily attributable to the increase in net loss of $32.4 million from $71.3 million for the year ended December 31, 2018, which included our company’s $15.0 million share of Nutrition Science Partner’s non-cash impairment provision, to $103.7 million for the year ended December 31, 2019. Additionally, the net change was also a result of a decrease in dividends received from equity investees of $7.1 million from $35.2 million for the year ended December 31, 2018 to $28.1 million for the year ended December 31, 2019. The net change was partially offset by the effects of changes in working capital. In particular, there was a $26.0 million increase in other payables, accruals and advance receipts for the year ended December 31, 2019, as compared to a $16.3 million increase for the year ended December 31, 2018.

Net cash used in operating activities was $8.9 million for the year ended December 31, 2017, compared to net cash used in operating activities of $32.8 million for the year ended December 31, 2018. The net change of $23.9 million was primarily attributable to the increase in net loss of $48.3 million from $23.0 million for the year ended December 31, 2017 to $71.3 million for the year ended December 31, 2018 which included our company’s $15.0 million share of Nutrition Science Partner’s non-cash impairment provision. See Item 4.B. “Business Overview—Overview of Our Collaborations—Nestlé Health Science” for more details relating to this impairment provision. Additionally, the net change was also a result of a decrease in dividends received from equity investees of $20.4 million from $55.6 million for the year ended December 31, 2017 to $35.2 million for the year ended December 31, 2018, which resulted from the relatively high level of dividends received from our non-consolidated joint venture Shanghai Hutchison Pharmaceuticals in the year ended December 31, 2017 following the one-time land compensation that it received from the Shanghai government. The net change was partially offset by the effects of changes in working capital. In particular, there was a $16.3 million increase in other payables, accruals and advance receipts for the year ended December 31, 2018, as compared to $5.2 million increase for the year ended December 31, 2017, and a $1.3 million increase in accounts payable for the year ended December 31, 2018, as compared to a $11.2 million decrease for the year ended December 31, 2017.

Net Cash generated from/(used in) Investing Activities

Net cash generated from investing activities was $43.8 million for the year ended December 31, 2018, compared to net cash generated from investing activities of $119.0 million for the year ended December 31, 2019. The net change of $75.2 million was primarily attributable to net withdrawal of deposits in short-term investments of $58.1 million for the year ended December 31, 2018 compared to the net withdrawal of deposits in short-term investments of $118.9 million for the year ended December 31, 2019. The net change was also attributable to the acquisition of 50% shareholding of Nutrition Science Partners held by our joint venture partner, which resulted in a net cash inflow of $8.7 million.

Net cash used in investing activities was $260.8 million for the year ended December 31, 2017, compared to net cash generated from investing activities of $43.8 million for the year ended December 31, 2018. The net change of $304.6 million was primarily attributable to the net deposits into short-term investments of $248.8 million for the year ended December 31, 2017 compared to net withdrawal of deposits in short-term investments of $58.1 million for the year ended December 31, 2018.

Net Cash (used in)/generated from Financing Activities

Net cash used in financing activities was $8.2 million for the year ended December 31, 2018, compared to net cash used in financing activities of $1.5 million for the year ended December 31, 2019. The net change of $6.7 million was primarily attributable to purchases of ADSs by our company for the settlement of certain equity awards totaling $0.3 million for the year ended December 31, 2019 as compared to $5.5 million for the year ended December 31, 2018, as well as the repayment of a $1.6 million loan to a non-controlling shareholder of a subsidiary in the year ended December 31, 2018.

Net cash generated from financing activities was $273.2 million for the year ended December 31, 2017, compared to net cash used in financing activities of $8.2 million for the year ended December 31, 2018. The net change of $281.4 million was primarily attributable to net proceeds of $292.7 million from the issuance of ordinary shares in the form of ADSs upon our follow-on offering in the Unites States in October 2017, as well as a net repayment of bank borrowings of $16.9 million in the year ended December 31, 2017, as compared to a net repayment of bank borrowings of $3.1 million in the year ended December 31, 2018.

Loan Facilities

In November 2015, our subsidiary Hutchison China MediTech (HK) Limited, or HCM HK, renewed a three-year revolving loan facility with HSBC with an interest rate at the Hong Kong Inter-bank Offered Rate, or HIBOR, plus 1.25% per annum. Upon maturity in November 2018, HCM HK further renewed this revolving loan facility for a further three years to November 2021.

Quantitative and Qualitative Disclosures About Market Risk

Foreign Exchange Risk

Substantially all of our revenue and expenses are denominated in renminbi, and our financial statements are presented in U.S. dollars. We do not believe that we currently have any significant direct foreign exchange risk and have not used any derivative financial instruments to hedge our exposure to such risk. Although, in general, our exposure to foreign exchange risks should be limited, the value of your investment in our ADSs will be affected by the exchange rate between the U.S. dollar and the renminbi because the value of our business is effectively denominated in renminbi, while the ADSs will be traded in U.S. dollars.

The value of the renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in China’s political and economic conditions. The conversion of renminbi into foreign currencies, including U.S. dollars, has been based on rates set by the PBOC. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the renminbi to the U.S. dollar. Under the revised policy, the renminbi is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy resulted in a more than 20% appreciation of the renminbi against the U.S. dollar in the following three years. Between July 2008 and June 2010, this appreciation halted, and the exchange rate between the renminbi and U.S. dollar remained within a narrow band. In June 2010, the PBOC announced that the PRC government would increase the flexibility of the exchange rate, and thereafter allowed the renminbi to appreciate slowly against the U.S. dollar within the narrow band fixed by the PBOC. At various times since then, the PBOC has significantly devalued the renminbi against the U.S. dollar. If we decide to convert renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the renminbi would have a negative effect on the U.S. dollar amounts available to us.

Credit Risk

Substantially all of our bank deposits are in major financial institutions, which we believe are of high credit quality. We limit the amount of credit exposure to any single financial institution. We make periodic assessments of the recoverability of trade and other receivables and amounts due from related parties. Our historical experience in collection of receivables falls within the recorded allowances, and we believe that we have made adequate provision for uncollectible receivables.

170

Interest Rate Risk

We have no significant interest-bearing assets except for bank deposits. Our exposure to changes in interest rates is mainly attributable to our bank borrowings, which bear interest at floating interest rates and expose us to cash flow interest rate risk. We have not used any interest rate swaps to hedge our exposure to interest rate risk. We have performed sensitivity analysis for the effects on our results for the year from changes in interest rates on floating rate borrowings. The sensitivity to interest rates used is based on the market forecasts available at the end of the reporting period and under the economic environments in which we operate, with other variables held constant. According to the analysis, the impact on our net loss of a 1.0% interest rate shift would be a maximum increase/decrease of $0.2 million for the year ended December 31, 2019.

Inflation

In recent years, China has not experienced significant inflation, and thus inflation has not had a material impact on our results of operations. According to the National Bureau of Statistics of China, the Consumer Price Index in China increased by 1.8%, 1.9% and 4.5% in 2017, 2018 and 2019, respectively. Although we have not been materially affected by inflation in the past, we can provide no assurance that we will not be affected in the future by higher rates of inflation in China.

Recently Issued Accounting Standards

In February 2016, the Financial Accounting Standards Board, or FASB, issued ASU 2016-02, Leases (Topic 842), or ASU 2016-02. The core principle of ASU 2016-02 is that a lessee should recognize the assets and liabilities that arise from leases. A lessee should recognize on the balance sheet a liability to make lease payments (the lease liability) and a right of use asset representing its right to use the underlying asset for the lease term. We elected the short-term lease exception to not recognize right-of-use assets and lease liabilities for leases with a term of 12 months or less and will recognize lease expense for such leases generally on a straight line basis over the lease term. ASU 2016-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2018. We adopted the new standard using the optional transition method (from ASU 2018-11, Leases Targeted Improvements) on January 1, 2019. A gross up to the consolidated balance sheet was recognized on the date of adoption of $5.7 million and $6.4 million in right-of-use assets and lease liabilities respectively, primarily related to our various factories and offices under non-cancellable lease agreements that were accounted as operating leases under ASC 840, Leases (Topic 840) as at December 31, 2019. Additionally, we do not expect a significant impact to the consolidated statements of operations after the adoption of ASC 842 as the pattern of expense recognition should not change materially for such operating leases.

In June 2016, the FASB issued ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss, or CECL, methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including accounts receivable and other receivables. We do not expect ASU 2016-13 to have a material impact to the consolidated financial statements.

Other amendments that have been issued by the FASB or other standards setting bodies that do not require adoption until a future date are not expected to have a material impact on our consolidated financial statements upon adoption.

Moreover, each of our executive officers has agreed, for the term of employment with us and for a period of twelve months thereafter, (i) not to undertake or be employed or interested directly or indirectly anywhere in Hong Kong in any activity which is similar to and competitive with our company or associated companies in which the executive officer had been involved in the period of 12 months prior to such termination and (ii) not to solicit for any employees of our company or our joint ventures or orders from any person, firm or company which was at any time during the 12 months prior to termination of such employment a customer or supplier of our company or associated companies.

Employment Agreements with Executive Officers at Hutchison MediPharma

We have also entered into employment agreements with each of our executive officers who are employed directly by Hutchison MediPharma, namely Dr. Weiguo Su, Dr. May Wang and Dr. Zhenping Wu. Under these employment agreements, we engage the executive officer on either an open-ended or a fixed term. Our executive officers receive compensation in the form of salaries, discretionary bonuses, annual leave, statutory maternity leave and nursing leave.

Under the terms of these agreements, we provide labor protection and work conditions that comply with the safety and sanitation requirements stipulated by the relevant PRC laws. The employment agreements prohibit the executive officers from engaging in any conduct and business activities which may compete with the business or interests of Hutchison MediPharma during the term of the executive officer’s employment. These executive officers also enjoy the Hutchison Provident Fund retirement scheme, medical coverage under the Hutchison Group Medical Scheme and personal accident insurance.

We may terminate an executive officer’s employment for cause at any time without notice. Termination for cause may include a serious breach of our internal rules and policies, serious negligence in the executive officer’s performance of his or her duties, an accusation or conviction of a criminal offence, acquisition of another job which materially affects the executive officer’s ability to perform his or her duties for our company and other circumstances stipulated by applicable PRC laws. We may terminate an executive officer’s employment with three months’ prior notice if the executive officer is unable to perform his or her duties (after the expiration of the prescribed medical treatment period) because of an illness or non-work-related injury or the executive officer is incompetent and remains incompetent after training or adjustment of his or her position. The executive officer may voluntarily terminate his or her contract without cause with three months’ prior notice. The executive officer may also terminate the employment agreement immediately for cause, which includes a failure by us to provide labor protection and the work conditions as specified under the employment agreement. In case of termination for any reason, we agree to make any mandatory severance payments required by the relevant PRC labor laws.

Equity Compensation Schemes and Other Benefit Plans

We have two share option schemes. We refer to these collectively as the Chi-Med Option Schemes. Our shareholder adopted the first Chi-Med Option Scheme, or the 2005 Chi-Med Option Scheme, in June 2005, and it was subsequently approved by the shareholders of Hutchison Whampoa Limited, our then majority shareholder, in May 2006 and later amended by our board of directors in March 2007. This share option scheme expired in 2016. In April 2015, our shareholders adopted the second Chi-Med Option Scheme, or the 2015 Chi-Med Option Scheme, which was later approved by the shareholders of CK Hutchison, the ultimate parent of our then majority shareholder, in May 2016.

We also have a long-term incentive scheme which was adopted by our shareholders in April 2015. We refer to this as our LTIP.

In addition, our subsidiary Hutchison MediPharma Holdings has two share option schemes. We refer to these collectively as the Hutchison MediPharma Option Schemes. The first Hutchison MediPharma Option Scheme, or the 2008 Hutchison MediPharma Option Scheme, was adopted in August 2008 upon approval by its shareholder. The 2008 Hutchison MediPharma Option Scheme was thereafter amended by the board of directors of Hutchison MediPharma Holdings in April 2011 and expired in 2014. The second Hutchison MediPharma Option Scheme, or the 2014 Hutchison MediPharma Option Scheme, was adopted in December 2014 upon approval by its shareholders.

Our Chi-Med Option Schemes, our LTIP and the 2014 Hutchison MediPharma Option Scheme each terminate on the tenth anniversary of their adoption. Each may also be terminated by its board of directors at any time. Any termination of the scheme is without prejudice to the awards outstanding at such time. Options are no longer being granted under the 2005 Chi-Med Option Scheme or the 2008 Hutchison MediPharma Option Scheme, but outstanding awards under the 2005 Chi-Med Option Scheme continue to be governed by the terms thereof.

The following describes the material terms of our Chi-Med Option Schemes, our LTIP and the Hutchison MediPharma Option Schemes, or collectively the Schemes.

Awards and Eligible Grantees. The Schemes provide for the award of share options exercisable for ordinary shares of our company (in the case of the Chi-Med Option Schemes) or ordinary shares of Hutchison MediPharma Holdings (in the case of the Hutchison MediPharma Option Schemes) to Eligible Employees (as defined in the Chi-Med Option Schemes) or non-executive directors (excluding any independent non-executive directors under the Chi-Med Option Schemes).

178

Under our LTIP, awards in the form of contingent rights to receive either shares or cash payments may be granted to the directors of our company, directors of our subsidiaries and employees of our company, subsidiaries, affiliates or such other companies as determined by our board of directors in its absolute discretion.

Scheme Administration. Our board of directors has delegated its authority for administering our Chi-Med Option Schemes and our LTIP to our remuneration committee. The board of directors of Hutchison MediPharma Holdings is responsible for administering the Hutchison MediPharma Option Schemes. Each such plan administrator has the authority to, among other things, select participants and determine the amount and terms and conditions of the awards under the applicable Schemes as it deems necessary and proper, subject to the restrictions described in “—Restrictions on Grants” below.

Restrictions on Grants. Under the Chi-Med Option Schemes, grants may not be made to independent non-executive directors. Furthermore, those grants may not be made to any of our employees or directors if such person is also a director, chief executive or substantial shareholder of any of our direct or indirect parent companies which is listed on a stock exchange or any of its associates without approval by the independent non-executive directors of such parent company (excluding any independent non-executive director who is a proposed grantee). In addition, approval by our shareholders and the shareholders of such listed parent company is required if an option grant under the Chi-Med Option Schemes is to be made to a substantial shareholder or independent non-executive director of a listed parent company or any of its associates and, upon exercise of such grant and any other grants made during the prior 12-month period to that shareholder, that individual would receive an amount of our ordinary shares equal or greater than 0.1% of our total outstanding shares or with an aggregate value in excess of HK$5 million (equivalent to $0.6 million as of December 31, 2017). The Hutchison MediPharma Option Schemes do not contain these restrictions.

In addition, options under our Chi-Med Option Schemes and the Hutchison MediPharma Option Schemes may not be granted to any individual if, upon the exercise of such options, the individual would receive an amount of shares when aggregated with all other options granted to such individual under the applicable Scheme in the 12-month period up to and including the grant date, that exceeds 1% of the total shares outstanding of the company granting the award on such date. In the event a grant of share options would exceed 1% of the total number of issued shares of Hutchison MediPharma Holdings, our company must also approve the grant. There are no individual limits under the LTIP.

Under our LTIP, no grant to any director, chief executive or substantial shareholder of our company may be made without the prior approval of our independent non-executive directors (excluding an independent non-executive director who is a proposed grantee).

Vesting. Vesting conditions of options granted under the Schemes are determined by the respective board of directors at the time of grant. Any options granted are normally exercisable to the extent vested within the period specified by the applicable Scheme, which ranges from six to ten years after the date of grant.

Under the Chi-Med Share Option Schemes and the Hutchison MediPharma Option Schemes, if a participant has committed any misconduct or any conduct making such participant’s service terminable for cause, all options (whether vested or unvested) lapse unless the respective board of directors otherwise determines in its absolute discretion. Options may be exercised to the extent vested where a participant’s service ceases due to the participant’s death, serious illness, injury, disability, retirement at the applicable retirement age, or earlier if determined by the participant’s employer, or if a participant’s service ceases for any other reason other than for cause.

Under the LTIP, if a participant’s employment or service with our company or its subsidiaries is terminated for cause or if the participant breaches certain provisions in the LTIP restricting the transfer of awards by grantees and imposing non-competition obligations on grantees, all unvested awards are automatically cancelled. Where a participant’s employment or service ceases for any reason other the reasons listed above (including due to the participant’s resignation, retirement, death or disability or upon the non-renewal of such participant’s employment or service agreement other than for cause), our board of directors may determine at its discretion whether unvested awards shall be deemed vested.

Exercise Price. The exercise price for each share pursuant to the initial options granted under the 2005 Chi-Med Option Scheme was a price determined by our board of directors at the date of grant, and for grants made thereafter, the exercise price was the Market Value of a share at the date of grant (as defined in the Chi-Med Option Schemes). The exercise price for each share pursuant to options granted under our 2008 Hutchison MediPharma Option Scheme was a price determined by the board of directors of Hutchison MediPharma Holdings.

179

The exercise price for each share pursuant to the options granted under the 2015 Chi-Med Option Scheme must be the Market Value of a share at the date of grant (as defined in the Chi-Med Option Schemes). The exercise price for each share pursuant to options granted under the 2014 Hutchison MediPharma Option Scheme will be determined by the boards of directors of Hutchison MediPharma Holdings at the date of grant.

Non-transferability of Awards. Awards may not be transferred except in the case of a participant’s death by the terms of each Scheme.

Takeover or Scheme of Arrangement. In the event of a general or partial offer for the shares of our company (under the Chi-Med Option Schemes) or Hutchison MediPharma Holdings (under the Hutchison MediPharma Option Schemes), whether by way of takeover, offer, share repurchase offer, or scheme of arrangement, the affected company is required to use all reasonable endeavors to procure that such offer is extended to all holders of options granted by such company on the same terms as those applying to shareholders. Both vested and unvested options may be exercised up until (i) the closing date of any such offer, (ii) the record date for entitlements under a scheme of arrangement, or (iii) two business days prior to any general meeting of members convened to consider such offer (under the 2014 Hutchison MediPharma Option Scheme), and will lapse thereafter. Certain options may also be exercised on a voluntary winding up of our company or Hutchison MediPharma Holdings, as the case may be.

Under our LTIP, in the event of a general offer for all the shares of our company, whether by way of takeover or scheme of arrangement, or if our company is to be voluntarily wound up, our board of directors shall determine in its discretion whether outstanding unvested awards will vest and the period within which such awards will vest.

Amendment. The Chi-Med Option Schemes require that amendments of a material nature only be made with the approval of our shareholders. The Hutchison MediPharma Option Schemes may be altered by the board of directors of our company or Hutchison MediPharma Holdings, as the case may be, but any amendments which provide a material advantage to grantees cannot take effect without shareholders’ approval.

Our board of directors may alter the LTIP, but amendments which are of a material nature cannot take effect without shareholders’ approval, unless the changes take effect automatically under the terms of the LTIP.

Authorized Shares. Subject to certain adjustments for share splits, share consolidations and other changes in capitalization, the maximum number of shares that may be issued upon exercise of all options granted may not in the aggregate exceed: (i) 4% of our shares outstanding on the date of adoption of the 2015 Chi-Med Option Scheme or (ii) 5% of the shares of Hutchison MediPharma Holdings outstanding on the date of adoption under the 2014 Hutchison MediPharma Option Scheme. In addition, under our 2015 Chi-Med Option Scheme, our board of directors may “refresh” the 4% scheme limit provided that the total number of shares which may be issued upon exercise of all options to be granted under the Chi-Med Option Schemes shall not exceed 10% of our total shares outstanding on such date. Further, the maximum number of shares that may be issued upon exercise of all options granted and not yet exercised under the 2015 Chi-Med Option Scheme, when combined with options granted and not yet exercised under any other schemes of our company or our subsidiaries must not exceed 10% of our shares outstanding on such date.

Share awards under our LTIP may not exceed 5% of our shares outstanding on the adoption date of the LTIP.

Outstanding Awards

In the year ended December 31, 2019, we granted options to purchase an aggregate of 2,315,000 ordinary shares, representing approximately 0.3% of our outstanding share capital, at a weighted average exercise price of £3.18 ($4.13) per share under the 2015 Chi Med Option Scheme. The options expire 10 years from the date of grant.

As of December 31, 2019, the following options were outstanding:

● options to purchase an aggregate of 1,516,180 ordinary shares, representing approximately 0.2% of our outstanding share capital, at a weighted average exercise price of £0.53 ($0.69) per share under the 2005 Chi Med Option Scheme, and

● options to purchase an aggregate of 17,916,380 ordinary shares, representing approximately 2.7% of the outstanding share capital, at a weighted average exercise price of £3.50 ($4.55) per share under the 2015 Chi Med Option Scheme.

180

In the year ended December 31, 2019, we granted awards under our LTIP to 11 senior managers, executives and directors, giving them a conditional right to receive ordinary shares to be purchased by the third-party trustee up to an aggregate maximum cash amount of $652,020. These awards are related to the achievement of performance targets. These LTIP awards vest after three years, subject to the continued employment of the LTIP holder. In the year ended December 31, 2019, we also granted a non-performance LTIP award of $96,154 to a senior executive, which vests after four years subject to the continued employment of the LTIP holder.

As of December 31, 2019, LTIP awards representing a maximum cash amount of $7,030,705 were outstanding.

C.   Board Practices.

Our board of directors consists of ten directors including four executive directors, two non-executive directors and four independent non-executive directors. Pursuant to a relationship agreement dated April 21, 2006, and amended and restated on June 13, 2019, by and between our company and Hutchison Whampoa (China) Limited, a parent company of Hutchison Healthcare Holdings Limited, or the Relationship Agreement, our board of directors must consist of at least one director who is independent of the CK Hutchison group if Hutchison Whampoa (China) Limited is entitled to cast at least 50% votes eligible to be cast on a poll vote at a general meeting of our company. The Relationship Agreement will continue in effect until our ordinary shares cease to be traded on the AIM market or the CK Hutchison group individually or collectively ceases to hold at least 30% of our shares.

Our directors are subject to a three-year term of office and hold office until such time as they wish to retire and not offer themselves up for re-election, are not re-elected by the shareholders, or are removed from office by special resolution at an annual general meeting of the shareholders. Under our articles of association, a director will be removed from office automatically if, among other things, the director (i) becomes bankrupt or makes any arrangement or composition with his creditors; or (ii) is found to be or becomes of unsound mind. For information regarding the period during which our officers and directors have served in their respective positions, please see Item 6.A. “Directors and Senior Management.”

Board Committees

Our board of directors has established an audit committee, remuneration committee, technical committee and nomination committee.

Audit Committee

Our audit committee consists of Graeme Jack, Paul Carter and Karen Ferrante, with Graeme Jack serving as chairman of the committee. Graeme Jack, Paul Carter and Karen Ferrante each meet the independence requirements under the rules of the Nasdaq Stock Market and under Rule 10A-3 under the Exchange Act. We have determined that Graeme Jack is an “audit committee financial expert” within the meaning of Item 407 of Regulation S-K. All members of our audit committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and the Nasdaq Stock Market.

Although we are a foreign private issuer, we are required to comply with Rule 10A-3 of the Exchange Act, relating to audit committee composition and responsibilities. Rule 10A-3 provides that the audit committee must have direct responsibility for the nomination, compensation and choice of our auditor, as well as control over the performance of their duties, management of complaints made, and selection of consultants. Under Rule 10A-3, if the governing law or documents of a listed issuer require that any such matter be approved by the board of directors or the shareholders of the company, the audit committee’s responsibilities or powers with respect to such matter may instead be advisory. Our articles of association provide that the audit committee may only have an advisory role and appointment of our auditor must be decided by our shareholders at our annual general meeting or at a subsequent extraordinary general meeting in each year.

The audit committee formally meets at least twice a year and otherwise as required. The audit committee’s purpose is to oversee our accounting and financial reporting process and the audit of our financial statements. Our audit committee’s primary duties and responsibilities are to:

● monitor the integrity of our financial statements, our annual and half-year reports and accounts and our announcements of interim or final results;

181

● provide advice, where requested by the board of directors, on whether the annual report and accounts, taken as a whole, are fair, balanced and understandable, and provide the information necessary for shareholders to assess our company’s position and performance, business model and strategy;

● review significant financial reporting issues and the judgments which they contain;

● review, whenever practicable without being inconsistent with any requirement for prompt reporting under applicable listing rules, other statements containing financial information such as significant financial returns to regulators and release of price sensitive information first where board of director approval is required; and

● review and challenge where necessary:

● the consistency of, and any changes to, accounting policies both on a year-on-year basis and across our company;

● the methods used to account for significant or unusual transactions where different approaches are possible;

● whether our company has followed appropriate accounting standards and made appropriate estimates and judgments, taking into account the views of the external auditor;

● the clarity of the disclosure in our financial reports and the context in which statements are made; and

● all material information presented with the financial statements, such as any operating and financial review and any corporate governance statements (insofar as it relates to the audit and risk management).

In relation to our internal controls and risk management systems, our audit committee, among other things:

● reviews the effectiveness of our internal control and risk management systems;

● reviews the policies and procedures for the identification, assessment and reporting of financial and non-financial risks and our management of those risks in accordance with the requirements of the Sarbanes-Oxley Act and other applicable laws, rules and regulations and the applicable requirements of any stock exchange;

● approves the appointment and removal of the head of the internal audit function;

● ensures our internal audit function has adequate standing and resources and is free from management or other restrictions;

● reviews and monitors our executive management’s responsiveness to the findings and recommendations of the internal audit function; and

● reviews with management and our independent auditors the adequacy and effectiveness of our internal control over financial reporting and disclosure controls and procedures.

In relation to our external auditor, our audit committee, among other things:

● recommends the appointment, reappointment or removal of the external auditor and considers any issues relating to their resignation, dismissal, remuneration or terms of engagement, subject to approval by the shareholders;

● considers and monitors the external auditor’s independence, objectivity and effectiveness;

● reviews and monitors the effectiveness of the audit process, considering relevant ethical or professional requirements;

● develops and implements policy on the engagement of the external auditor to provide non-audit services, taking into any relevant ethical guidance; and

182

● pre-approves the external auditors’ annual audit fees and the nature and scope of proposed audit coverage, subject to approval by our shareholders.

The audit committee is authorized to obtain, at our company’s expense, reasonable outside legal or other professional advice on any matters within the scope of its responsibilities.

Remuneration Committee

Our remuneration committee consists of Paul Carter, Graeme Jack and Simon To, with Paul Carter serving as chairman of the committee. The remuneration committee is responsible for considering all material elements of remuneration policy and remuneration and incentives of our executive directors and key employees with reference to independent remuneration research and professional advice. The remuneration committee meets formally at least once each year and otherwise as required and make recommendations to our board of directors on the framework for executive remuneration and on proposals for the granting of share options and other equity incentives. Our board of directors is responsible for implementing these recommendations and agreeing the remuneration packages of individual directors. No director is permitted to participate in discussions or decisions concerning his or her own remuneration.

Technical Committee

Our technical committee consists of Karen Ferrante, Paul Carter, Simon To, Christian Hogg, Weiguo Su and Tony Mok, with Karen Ferrante serving as chairperson of the committee. The technical committee’s responsibility is to consider, from time to time, matters relating to the technical aspects of the research and development activities of our Innovation Platform. It invites such executives as it deems appropriate to participate in meetings from time to time.

Nomination Committee

Our nomination committee consists of all of our directors, with Simon To serving as chairman of the committee. Our nomination committee reviews the structure, size, diversity profile and skills set of the board against its needs and makes recommendations on the composition of the board to achieve our corporate strategy as well as promote shareholder value. It facilitates the board in the conduct of the selection and nomination of directors, makes recommendations to the board on the appointment or reappointment of directors and succession planning for directors. It also assesses director independence having regard to the criteria under the applicable corporate governance code, SEC or stock exchange rules.

U.K. Corporate Governance Code

The U.K. Corporate Governance Code 2018 published by the U.K. Financial Reporting Council, or the 2018 Code, is the primary source of corporate governance standards for all companies with a premium listing on the Official List of the U.K. Financial Conduct Authority, whether incorporated in the United Kingdom or elsewhere, and it is recognized as a best practice for the largest companies by market capitalization on the AIM market of the London Stock Exchange. The 2018 Code is comprised of main and supporting principles of good governance addressing the following areas: (i) board leadership and company purpose; (ii) division of responsibilities; (iii) board composition, succession and evaluation; (iv) audit, risk and internal control; and (v) remuneration. Together with the U.K. Financial Reporting Council’s Guidance on Board Effectiveness (published in July 2018), it also includes detailed recommendations derived from these principles, such as the roles of board chairman and chief executive officer should not be exercised by the same individual and the chairman of the board should ensure that new directors receive a full, formal and tailored induction on joining the board. The 2018 Code applies to accounting periods beginning on or after January 1, 2019. For the year ended December 31, 2019, we have voluntarily complied with many of the principles of the U.K. Corporate Governance Code.

Code of Ethics

Our board of directors has adopted a code of ethics to set standards for our directors, officers and employees as are reasonably necessary to promote (i) honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; (ii) full, fair, accurate, timely and understandable disclosure in the reports and documents that we file or submit to the applicable stock exchanges, and in any other public communications; (iii) compliance with applicable governmental and regulatory laws, rules, codes and regulations; (iv) prompt internal reporting of any violations of the code of ethics; and (v) accountability for adherence to the code of ethics.

183

Code of Ethics for Business Partners

Our board of directors has adopted a code of ethics for our business partners, including our suppliers, vendors, customers, agents, contractors, joint venture partners and representatives. This code of ethics contains general guidelines to promote the standards outlined in our internal code of ethics as described above.

Complaints Procedures

Our board of directors has adopted procedures for the confidential receipt, retention, and treatment of complaints from, or concerns raised by, employees regarding accounting, internal accounting controls and auditing matters as well as illegal or unethical matters. The complaint procedures are reviewed by the audit committee from time to time as warranted to ensure their continuing compliance with applicable laws and listing standards as well as their effectiveness.

Information Security Policy

Our board of directors has adopted an information security policy to define and help communicate the common policies for information confidentiality, integrity and availability to be applied to us and our joint ventures. The purpose of the information security policy is to ensure business continuity by preventing and minimizing the impact of security risks within our company and our joint ventures. Our information security policy applies to all of our and our joint ventures’ business entities across all countries. It applies to the creation, communication, storage, transmission and destruction of all different types of information. It applies to all forms of information, including but not limited to electronic copies, hardcopy, and verbal disclosures whether in person, over the telephone, or by other means.

Code on Dealings in Shares

Our board of directors has adopted a policy on the handling of material inside information, consisting of information which is either “inside information” under the EU Market Abuse Regulation (Regulation (EU) 596/2014), or MAR, or “material non-public information” under U.S. law. This policy, among other things, prohibits any employees, directors, other persons discharging managerial responsibilities or their connected persons dealing in our securities or their derivatives, or those of our collaborators, business partners, suppliers and customers, while in possession of material inside information. Certain members of our senior management or staff, including persons discharging managerial responsibilities, and their connected persons are subject to additional compliance requirements which are outlined in the code (including but not limited to obtaining written pre-clearance from designated members of management prior to any dealing in any such securities is allowed).

Board Diversity Policy

Our board of directors has established a board diversity policy as our board of directors recognizes the benefits of a board of directors that possesses a balance of skills, experience, expertise, independence and knowledge and diversity of perspectives appropriate to the requirements of our businesses.

We maintain that appointment to our board of directors should be based on merit that complements and expands the skills, experience, expertise, independence and knowledge of the board of directors as a whole, taking into account gender, age, professional experience and qualifications, cultural and educational background, and any other factors that our board of directors might consider relevant and applicable from time to time towards achieving a diverse board of directors.

Relationship with CK Hutchison

Letters of awareness with respect to loans

CK Hutchison has provided letters of awareness to certain of our lenders stating that it is aware that loan facilities have been provided to us and that its current intention is that for so long as amounts are outstanding under such loan facilities, it will not reduce its direct or indirect shareholding in our company to below 40% of our issued share capital while such loans are outstanding.

Relationship Agreement with the CK Hutchison group

We entered into a relationship agreement dated April 21, 2006, which was amended and restated on June 13, 2019 with effect from June 3, 2015, with Hutchison Whampoa (China) Limited, which is an indirect wholly owned subsidiary of CK Hutchison, with a view to ensuring that our company is capable of carrying on its business independently of the CK Hutchison group. We refer to this agreement as the Relationship Agreement. The Relationship Agreement provides, among other things, that all transactions between any of us or our joint ventures, on the one hand, and the CK Hutchison group, on the other hand, will be on an arm’s length basis, on normal commercial terms and in a manner consistent with the AIM Rules. The Relationship Agreement further provides that the approval of our board of directors shall be required for any transaction between any of us or our joint ventures, on one hand, and the CK Hutchison group, on the other hand, and that in approving any such transaction, our board of directors must consist of at least one director who is independent of CK Hutchison. Our board of directors must consist of at least one director who is independent of the CK Hutchison group if Hutchison Whampoa (China) Limited is entitled to cast at least 50% votes eligible to be cast on a poll vote at a general meeting of our company, see Item 6.C. “Directors, Senior Management and Employees—Board Practices.” Hutchison Whampoa (China) Limited has also agreed to procure that each member of the Hutchison Whampoa (China) Limited group will not exercise its voting rights and powers so as to amend our memorandum or articles of association in a manner which is inconsistent with the Relationship Agreement. The Relationship Agreement will continue until the first to occur of: (i) our shares ceasing to be traded on the AIM market or (ii) the CK Hutchison group individually or collectively cease to hold or control the exercise of at least 30% or more of the rights to vote at our general meetings.

Products sold to group companies of CK Hutchison

We have entered into agreements with members of the CK Hutchison group, including the retail grocery and pharmacy chains PARKnSHOP and Watsons which are owned and operated by the A.S. Watson Group, an indirect subsidiary of CK Hutchison, in respect of the distribution of certain of our Commercial Platform products. For the year ended December 31, 2019, sales of our products to members of the CK Hutchison group amounted to $7.6 million. In addition, for the year ended December 31, 2019, we paid approximately $0.4 million to members of the CK Hutchison group for the provision of marketing services associated with these products. Our sales to CK Hutchison group companies are made pursuant to purchase orders issued by each purchaser periodically, the terms of which are on an arm’s length basis on normal commercial terms.

See Item 3.D. “Risk Factors—Risks Relating to Our Dependence on Third Parties—There is no assurance that the benefits currently enjoyed by virtue of our association with CK Hutchison will continue to be available” for more information on the risks associated with our relationship with CK Hutchison’s group companies.

Intellectual property licensed by the CK Hutchison group

We conduct our business using trademarks with various forms of the “Hutchison,” “Chi-Med” and “China-MediTech” brands, as well as domain names incorporating some or all of these trademarks. We have entered into a brand license agreement dated April 21, 2006 (as amended and restated on June 13, 2019 with effect from June 3, 2015) with Hutchison Whampoa Enterprises Limited, which is an indirect wholly owned subsidiary of CK Hutchison, pursuant to which we have been granted a non-exclusive, non-transferrable, royalty-free right to use such trademarks, domain names and other intellectual property rights owned by the CK Hutchison group in connection with the operation of our business worldwide. We refer to this amended and restated agreement as the Brand License Agreement. We are also permitted to sub-license such intellectual property rights to our affiliates.

The Brand License Agreement contains provisions on quality control pursuant to which we are obliged to use the brands and related materials in compliance with the brand guidelines, industry best practice and other quality directives issued by Hutchison Whampoa Enterprises Limited from time to time. Under this agreement, we assign all intellectual property rights, including future copyrights in any works incorporating brand-related material or translations thereof, to Hutchison Whampoa Enterprises Limited (subject to any third-party rights).

Hutchison Whampoa Enterprises Limited may terminate the Brand License Agreement (or any sub-license) if, among other things, we commit a material breach of the agreement, or within any twelve-month period aggregate direct or indirect shareholding in our company held by Hutchison Whampoa Limited, our indirect shareholder, is reduced to less than 40%, 30% or 20%. On termination of the Brand License Agreement, we (and any sub-licensees) must immediately cease using the brands and are obliged to withdraw from sale any products bearing the brands; provided that if the agreement is terminated following a change in Hutchison Whampoa Limited’s aggregate direct or indirect shareholding in our company, we will have a six-month transitional period during which we can continue to use the licensed rights. Hutchison Whampoa Limited’s interest in our company is less than 20%, but we do not anticipate that Hutchison Whampoa Enterprises Limited will terminate such license in the foreseeable future.

Hutchison Whampoa Enterprises Limited has also granted a royalty-free license to use the Hutchison name and associated trademarks to Hutchison Baiyunshan. The license has a term equal to the operational period of the joint venture but may be terminated by the licensor if, among other things, Hutchison Baiyunshan is in breach of the terms of the license and fails to remedy that breach after an arbitration award is issued against Hutchison Baiyunshan, the joint venture agreement terminates, or our company’s interest in Hutchison Baiyunshan falls below 50%.

188

Sharing of services with the CK Hutchison group

Pursuant to an amended and restated services agreement dated January 1, 2016 between us and Hutchison Whampoa (China) Limited, an indirect wholly owned subsidiary of CK Hutchison, we share certain services with and receive operational support from the CK Hutchison group including, among others, legal and regulatory services, company secretarial support services, tax and internal audit services, shared use of accounting software system and related services, participation in the CK Hutchison group’s pension, medical and insurance plans, participation in the CK Hutchison group’s procurement projects with third-party vendors/suppliers, other staff benefits and staff training services, company functions and activities and operation advisory and support services. We refer to this amended and restated agreement as the Services Agreement. The Services Agreement replaces our prior services agreement with Hutchison Whampoa (China) Limited, dated April 21, 2006, which had substantially similar terms. We pay a management fee to Hutchison Whampoa (China) Limited for the provision of such services. In addition, we make payments under the Services Agreement to Hutchison Whampoa (China) Limited for our executive offices in Hong Kong. Furthermore, pursuant to the terms of the Services Agreement, Hutchison Whampoa (China) Limited charges us management fees and other costs through Hutchison Healthcare Holdings Limited, its wholly owned subsidiary.

The Services Agreement may be terminated by either party by giving three months’ written notice. Hutchison Whampoa (China) Limited may also immediately terminate if its shareholding in our company falls below 30%. The services provided under the Services Agreement are provided on an arm’s length basis, on normal commercial terms.

Any amount unpaid after 30 days accrues interest at the rate of 1.5% per annum. In the year ended December 31, 2019, we paid a management fee of approximately $0.9 million under the Services Agreement. As of December 31, 2019, we had $0.4 million in unpaid fees outstanding to Hutchison Whampoa (China) Limited.

Relationships with our Joint Ventures

Shanghai Hutchison Pharmaceuticals’ provision of promotion and marketing services to Hutchison Sinopharm. Hutchison Sinopharm entered into an agreement with our non-consolidated joint venture Shanghai Hutchison Pharmaceuticals to provide certain promotion and marketing services within China for Seroquel. Under this agreement, Shanghai Hutchison Pharmaceuticals managed marketing and was paid a service fee for medical sales services, and Hutchison Sinopharm manages distribution and logistics for this product. In May 2019, we received a notice from Luye HK purporting to terminate Shanghai Hutchison Pharmaceuticals’ rights to distribute Seroquel. See Item 4.B. “Business Overview—Our Commercial Platform—Prescription Drug Business—Hutchison Sinopharm” for further details regarding the current status of our Seroquel marketing and distribution rights. Prior to this purported termination, Hutchison Sinopharm paid Shanghai Hutchison Pharmaceuticals $2.7 million in connection with the provision of such services in the year ended December 31, 2019.

Except as otherwise disclosed in this annual report (including the exhibits hereto), we are not currently, and have not been in the last two years, party to any material contract, other than contracts entered into in the ordinary course of our business.

D.    Exchange Controls.

Foreign currency exchange in the PRC is primarily governed by the Foreign Exchange Administration Rules issued by the State Council on January 29, 1996 and effective as of April 1, 1996 (and amended on January 14, 1997 and August 1, 2008) and the Regulations of Settlement, Sale and Payment of Foreign Exchange which came into effect on July 1, 1996.

Under the Foreign Exchange Administration Rules, renminbi is freely convertible for current account items, including the distribution of dividends payments, interest payments, and trade and service-related foreign exchange transactions. Conversion of renminbi for capital account items, such as direct investment, loans, securities investment and repatriation of investment, however, is still generally subject to the approval or verification of the SAFE.

Under the Regulations of Settlement, Sale and Payment of Foreign Exchange, foreign invested enterprises including wholly foreign owned enterprises, may buy, sell or remit foreign currencies only at those banks that are authorized to conduct foreign exchange business after providing such banks with valid commercial supporting documents and, in the case of capital account item transactions, after obtaining approvals from the SAFE. Capital investments by foreign invested enterprises outside the PRC are also subject to limitations, which include approvals by the MOFCOM, the SAFE and the NDRC.

In March 2015, the SAFE released the Circular on Reforming the Management Approach regarding the Foreign Exchange Capital Settlement of Foreign-invested Enterprises, or FIEs, or the Foreign Exchange Capital Settlement Circular, which became effective from June 1, 2015. This circular replaced the SAFE’s previous related circulars, including the Circular on Issues Relating to the Improvement of Business Operation with Respect to the Administration of Foreign Exchange Capital Payment and Settlement of Foreign Invested Enterprises. The Foreign Exchange Capital Settlement Circular clarifies that FIEs may settle a specified proportion of their foreign exchange capital in banks at their discretion, and may choose the timing for such settlement. The proportion of foreign exchange capital to be settled at FIEs’ discretion for the time being is 100% and the SAFE may adjust the proportion in due time based on the situation of international balance of payments. The circular also stipulates that FIEs’ usage of capital and settled foreign exchange capital shall comply with relevant provisions concerning foreign exchange control and be subject to the management of a negative list. The FIEs’ capital and Renminbi capital gained from the settlement of foreign exchange capital may not be directly or indirectly used for expenditure beyond the business scope of the FIEs or as prohibited by laws and regulations of the PRC. Such capital also may not be directly or indirectly used for issuing renminbi entrusted loans except as permitted by the business scope of the FIE, for repaying inter-enterprise borrowings including any third-party advance, or for repaying the bank loans denominated in renminbi that have been sub-lent to a third party.

In addition, the payment of dividends by entities established in the PRC is subject to limitations. Regulations in the PRC currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in the PRC. Each of our PRC subsidiaries and joint ventures that is a domestic company is also required to set aside at least 10.0% of its after-tax profit based on PRC accounting standards each year to its general reserves or statutory capital reserve fund until the accumulative amount of such reserves reach 50.0% of its respective registered capital. These restricted reserves are not distributable as cash dividends. In addition, if any of our PRC subsidiaries or joint ventures incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us.

For more information about foreign exchange control, see Item 3.D. “Risk Factors—Other Risks and Risks Relating to Doing Business in China—Restrictions on currency exchange may limit our ability to receive and use our revenue effectively.”

E.    Taxation

The following is a general summary of certain PRC, Hong Kong, Cayman Islands and U.S. federal income tax consequences relevant to the acquisition, ownership and disposition of our ADSs. The discussion is not intended to be, nor should it be construed as, legal or tax advice to any particular individual. The discussion is based on laws and relevant interpretations thereof in effect as of March 1, 2020, all of which are subject to change or different interpretations, possibly with retroactive effect. The discussion does not address U.S. state or local tax laws, or tax laws of jurisdictions other than the PRC, Hong Kong, the Cayman Islands and the United States. You should consult your own tax advisors with respect to the consequences of acquisition, ownership and disposition of our ADSs and ordinary shares.

Taxation in the PRC

PRC Enterprise Income Tax

Under the EIT Law, which was promulgated on March 16, 2007 and subsequently amended on February 24, 2017 and December 29, 2018, and its implementation rules which became effective on January 1, 2008, the standard tax rate of 25% applies to all enterprises (including FIEs) with exceptions in special situations if relevant criteria are met and subject to the approval of the PRC tax authorities.

An enterprise incorporated outside of the PRC whose “de facto management bodies” are located in the PRC is considered a “resident enterprise” and will be subject to a uniform EIT rate of 25% on its global income. In April 2009, the SAT, in Circular 82, specified certain criteria for the determination of what constitutes “de facto management bodies.” If all of these criteria are met, the relevant foreign enterprise will be deemed to have its “de facto management bodies” located in the PRC and therefore be considered a resident enterprise in the PRC. These criteria include: (a) the enterprise’s day-to-day operational management is primarily exercised in the PRC; (b) decisions relating to the enterprise’s financial and human resource matters are made or subject to approval by organizations or personnel in the PRC; (c) the enterprise’s primary assets, accounting books and records, company seals, and board and shareholders’ meeting minutes are located or maintained in the PRC; and (d) 50% or more of voting board members or senior executives of the enterprise habitually reside in the PRC. In addition, an enterprise established outside the PRC which meets all of the aforesaid requirements is expected to make an application for the classification as a “resident enterprise” and this will ultimately be confirmed by the province-level tax authority. Although Circular 82 only applies to foreign enterprises that are majority-owned and controlled by PRC enterprises, not those owned and controlled by foreign enterprises or individuals, the determining criteria set forth in Circular 82 may be adopted by the PRC tax authorities as the test for determining whether the enterprises are PRC tax residents, regardless of whether they are majority-owned and controlled by PRC enterprises. However, it is not entirely clear how the PRC tax authorities will determine whether a non-PRC entity (that has not already been notified of its status for EIT purposes) will be classified as a “resident enterprise” in practice.

Except for our PRC subsidiaries and joint ventures incorporated in China, we believe that none of our entities incorporated outside of China is a PRC resident enterprise for PRC tax purposes. However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities, and uncertainties remain with respect to the interpretation of the term “de facto management body.”

If a non-PRC enterprise is classified as a “resident enterprise” for EIT purposes, any dividends to be distributed by that enterprise to non-PRC resident shareholders or ADS holders or any gains realized by such investors from the transfer of shares or ADSs may be subject to PRC tax. If the PRC tax authorities determine that we should be considered a PRC resident enterprise for EIT purposes, any dividends payable by us to our non-PRC resident enterprise shareholders or ADS holders, as well as gains realized by such investors from the transfer of our shares or ADSs may be subject to a 10% withholding tax, unless a reduced rate is available under an applicable tax treaty. Furthermore, if we are considered a PRC resident enterprise for EIT purposes, it is unclear whether our non-PRC individual shareholders (including our ADS holders) would be subject to any PRC tax on dividends or gains obtained by such non-PRC individual shareholders. If any PRC tax were to apply to dividends realized by non-PRC individuals, it would generally apply at a rate of up to 20% unless a reduced rate is available under an applicable tax treaty.

192

According to the EIT Law, dividends declared after January 1, 2008 and paid by PRC FIEs to their non-PRC parent companies will be subject to PRC withholding tax at 10% unless there is a tax treaty between the PRC and the jurisdiction in which the overseas parent company is a tax resident and which specifically exempts or reduces such withholding tax, and such tax exemption or reduction is approved by the relevant PRC tax authorities. Pursuant to the Arrangement, if the non-PRC immediate holding company is a Hong Kong tax resident and directly holds a 25% or more equity interest in the PRC enterprise and is considered to be the beneficial owner of dividends paid by the PRC enterprise, such withholding tax rate may be lowered to 5%, subject to approval by the relevant PRC tax authorities in accordance with relevant tax regulations upon the assessment of beneficial ownership.

Value Added Tax

The Interim Regulations of the PRC on VAT, or the VAT Regulations, came into effect on January 1, 2009 (subsequently amended on February 6, 2016 and November 19, 2017). Pursuant to the VAT Regulations, VAT is imposed on the goods sold in or imported into the PRC and on processing, repair and replacement services provided within the PRC.

The MOF, and the SAT jointly promulgated the Circular on Comprehensively Promoting the Pilot Program of the Collection of VAT in Lieu of Business Tax, or the 2016 VAT Circular, on March 23, 2016, which came into effect on May 1, 2016. Pursuant to the 2016 VAT Circular, the sale of services, intangible assets or real property within the PRC (including when either party of a transaction is within the PRC unless in specified situations) is subject to VAT instead of Business Tax, with VAT rates being 6%, 11% or 17% and could be zero for certain specified cross border taxable items/services, in accordance with the relevant regulations. Certain specified technology transfer/development related income are exempt from VAT, subject to approval of relevant tax authorities. According to the Notice of the MOF and the SAT on Adjusting VAT Rates, which was promulgated on April 4, 2018 and became effective on May 1, 2018, the VAT rates are revised to 6%, 10% or 16%. The Public Notice regarding certain Policies for Deepening the VAT Reform was promulgated on March 20, 2019 and became effective on April 1, 2019, whereby VAT rates are further revised to 6%, 9% or 13%.

A Municipal Maintenance Tax, together with Education Surcharge and a Local Education Surcharge, are payable at a rate, in aggregate, of 6% to 12% of the VAT paid.

Overview of Tax Implications of Various Other Jurisdictions

Cayman Islands Taxation

According to our Cayman Islands counsel, Conyers Dill & Pearman, the Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within the jurisdiction of the Cayman Islands. The Cayman Islands is a party to a double tax treaty entered into with the United Kingdom in 2010 but it is otherwise not a party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

Pursuant to the Tax Concessions Law (1999 Revision) of the Cayman Islands, Hutchison China MediTech Limited has obtained an undertaking from the Governor-in-Council: (a) that no law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciations shall apply to us or our operations; and (b) that the aforesaid tax or any tax in the nature of estate duty or inheritance tax shall not be payable on its shares, debentures or other obligations.

The undertaking is for a period of twenty years from January 9, 2001.

Hong Kong Taxation

Profits Tax

Hutchison China MediTech Limited is a Hong Kong tax resident. Hong Kong tax residents are subject to Hong Kong Profits Tax in respect of profits arising in or derived from Hong Kong at the current rate of 16.5% (except portions eligible for the two-tiered profits tax as discussed above). Dividend income earned by a Hong Kong tax resident is generally not subject to Hong Kong Profits Tax.

193

Hong Kong tax on shareholders and ADS holders

No tax is payable in Hong Kong in respect of dividends paid by a Hong Kong tax resident to their shareholders, including our ADS holders.

Hong Kong Profits Tax will not be payable by our shareholders, including our ADS holders (other than shareholders / ADS holders carrying on a trade, profession or business in Hong Kong and holding the shares / ADSs for trading purposes), on any capital gains made on the sale or other disposal of the ADSs. Shareholders, including our ADS holders, should take advice from their own professional advisors as to their particular tax position.

No Hong Kong Stamp Duty is payable by our shareholders, including our ADS holders.

Material U.S. Federal Income Tax Considerations

The following summary, subject to the limitations set forth below, describes the material U.S. federal income tax consequences for a U.S. Holder (as defined below) of the acquisition, ownership and disposition of ordinary shares and ADSs. This discussion is limited to U.S. Holders who hold such ordinary shares or ADSs as capital assets (generally, property held for investment). For purposes of this summary, a “U.S. Holder” is a beneficial owner of an ordinary share or ADS that is for U.S. federal income tax purposes:

● a citizen or individual resident of the United States;

● a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof, or the District of Columbia;

● an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

● a trust if (i) it has a valid election in effect to be treated as a U.S. person for U.S. federal income tax purposes or (ii) a U.S. court can exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions.

Except as explicitly set forth below, this summary does not address aspects of U.S. federal income taxation that may be applicable to U.S. Holders subject to special rules, including:

● banks or other financial institutions;

● insurance companies;

● real estate investment trusts;

● regulated investment companies;

● grantor trusts;

● tax-exempt organizations;

● persons holding our ordinary shares or ADSs through a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) or S corporation;

● dealers or traders in securities, commodities or currencies;

● persons whose functional currency is not the U.S. dollar;

● certain former citizens and former long-term residents of the United States;

194

● persons holding our ordinary shares or ADSs as part of a position in a straddle or as part of a hedging, conversion or integrated transaction for U.S. federal income tax purposes; or

● direct, indirect or constructive owners of 10% or more of our equity (by vote or value).

In addition, this summary does not address the U.S. federal estate and gift tax or the alternative minimum tax consequences of the acquisition, ownership, and disposition of our ordinary shares or ADSs. We have not received nor do we expect to seek a ruling from the U.S. Internal Revenue Service, or the IRS, regarding any matter discussed herein. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of those set forth below. Each prospective investor should consult its own tax advisors with respect to the U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of our ordinary shares and ADSs.

This discussion is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, U.S. Treasury Regulations promulgated thereunder and administrative and judicial interpretations thereof, and the income tax treaty between the PRC and the United States, or the U.S.-PRC Tax Treaty, each as available and in effect on the date hereof, all of which are subject to change or differing interpretations, possibly with retroactive effect, which could affect the tax consequences described herein. In addition, this summary is based, in part, upon representations made by the depositary to us and assumes that the deposit agreement, and all other related agreements, will be performed in accordance with their terms.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our ordinary shares or ADSs, the tax treatment of the partnership and a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Such partner or partnership should consult its own tax advisors as to the U.S. federal income tax consequences of acquiring, owning and disposing of our ordinary shares or ADSs.

PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH REGARD TO THE PARTICULAR TAX CONSEQUENCES APPLICABLE TO THEIR SITUATIONS AS WELL AS THE APPLICATION OF ANY U.S. FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS.

ADSs

A U.S. Holder of ADSs will generally be treated, for U.S. federal income tax purposes, as the owner of the underlying ordinary shares that such ADSs represent. Accordingly, no gain or loss will be recognized if a U.S. Holder exchanges ADSs for the underlying shares represented by those ADSs.

The U.S. Treasury has expressed concern that parties to whom ADSs are released before shares are delivered to the depositary or intermediaries in the chain of ownership between holders and the issuer of the security underlying the ADSs, may be taking actions that are inconsistent with the claiming of foreign tax credits by U.S. Holders of ADSs. These actions would also be inconsistent with the claiming of the reduced rate of tax, described below, applicable to dividends received by certain non-corporate U.S. Holders. Accordingly, the creditability of non-U.S. withholding taxes (if any), and the availability of the reduced tax rate for dividends received by certain non-corporate U.S. Holders, each described below, could be affected by actions taken by such parties or intermediaries. For purposes of the discussion below, we assume that intermediaries in the chain of ownership between the holder of an ADS and us are acting consistently with the claim of U.S. foreign tax credits by U.S. Holders.

195

Taxation of Dividends

As described in “Dividend Policy” above, we do not currently anticipate paying any distributions on our ordinary shares or ADSs in the foreseeable future. However, to the extent there are any distributions made with respect to our ordinary shares or ADSs, and subject to the discussion under “—Passive Foreign Investment Company Considerations” below, the gross amount of any such distribution (including withheld taxes, if any) made out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) will generally be taxable to a U.S. Holder as ordinary dividend income on the date such distribution is actually or constructively received. Distributions in excess of our current and accumulated earnings and profits will be treated as a non-taxable return of capital to the extent of the U.S. Holder’s adjusted tax basis in the ordinary shares or ADSs, as applicable, and thereafter as capital gain. However, because we do not maintain calculations of our earnings and profits in accordance with U.S. federal income tax accounting principles, U.S. Holders should expect to treat distributions paid with respect to our ordinary shares and ADSs as dividends. Dividends paid to corporate U.S. Holders generally will not qualify for the dividends received deduction that may otherwise be allowed under the Code. This discussion assumes that distributions made by us, if any, will be paid in U.S. dollars.

Dividends paid to a non-corporate U.S. Holder by a “qualified foreign corporation” may be subject to reduced rates of U.S. federal income taxation if certain holding period and other requirements are met. A qualified foreign corporation generally includes a foreign corporation (other than a PFIC) if (1) its ordinary shares (or ADSs backed by ordinary shares) are readily tradable on an established securities market in the United States or (2) it is eligible for benefits under a comprehensive U.S. income tax treaty that includes an exchange of information program and which the U.S. Treasury Department has determined is satisfactory for these purposes.

IRS guidance indicates that our ADSs (which are listed on the Nasdaq Global Select Market) are readily tradable for purposes of satisfying the conditions required for these reduced tax rates. We do not expect, however, that our ordinary shares will be listed on an established securities market in the United States and therefore do not believe that any dividends paid on our ordinary shares that are not represented by ADSs currently meet the conditions required for these reduced tax rates. There can be no assurance that our ADSs will be considered readily tradable on an established securities market in subsequent years.

The United States does not have a comprehensive income tax treaty with the Cayman Islands. However, in the event that we were deemed to be a PRC resident enterprise under the EIT Law (see “—Taxation in the PRC” above), although no assurance can be given, we might be considered eligible for the benefits of the U.S.-PRC Tax Treaty for purposes of these rules. U.S. Holders should consult their own tax advisors regarding the availability of the reduced tax rates on dividends paid with respect to our ordinary shares or ADSs in light of their particular circumstances.

Non-corporate U.S. Holders will not be eligible for reduced rates of U.S. federal income taxation on any dividends received from us if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year unless, under certain circumstances, the “deemed sale election” described below under “—Passive Foreign Investment Company Considerations—Status as a PFIC” has been made.

In the event that we were deemed to be a PRC resident enterprise under the EIT Law (see “—Taxation in the PRC” above), U.S. Holders might be subject to PRC withholding taxes on dividends paid by us. In that case, subject to certain conditions and limitations, such PRC withholding tax may be treated as a foreign tax eligible for credit against a U.S. Holder’s U.S. federal income tax liability under the U.S. foreign tax credit rules. For purposes of calculating the U.S. foreign tax credit, dividends paid on our ordinary shares or ADSs, will be treated as income from sources outside the United States and will generally constitute passive category income. If a U.S. Holder is eligible for U.S.-PRC Tax Treaty benefits, any PRC taxes on dividends will not be creditable against such U.S. Holder’s U.S. federal income tax liability to the extent such tax is withheld at a rate exceeding the applicable U.S.-PRC Tax Treaty rate. An eligible U.S. Holder who does not elect to claim a foreign tax credit for PRC tax withheld may instead be eligible to claim a deduction, for U.S. federal income tax purposes, in respect of such withholding but only for the year in which such U.S. Holder elects to do so for all creditable foreign income taxes. The U.S. foreign tax credit rules are complex. U.S. Holders should consult their own tax advisors regarding the foreign tax credit rules in light of their particular circumstances.

196

Taxation of Capital Gains

Subject to the discussion below in “—Passive Foreign Investment Company Considerations,” upon the sale, exchange, or other taxable disposition of our ordinary shares or ADSs, a U.S. Holder generally will recognize gain or loss in an amount equal to the difference between the amount realized on such sale or exchange (determined in the case of sales or exchanges in currencies other than U.S. dollars by reference to the spot exchange rate in effect on the date of the sale or exchange or, if sold or exchanged on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, the spot exchange rate in effect on the settlement date) and the U.S. Holder’s adjusted tax basis in such ordinary shares or ADSs determined in U.S. dollars. A U.S. Holder’s initial tax basis will be the U.S. Holder’s U.S. dollar purchase price for such ordinary shares or ADSs.

Assuming we are not a PFIC and have not been treated as a PFIC during the U.S. Holder’s holding period for its ordinary shares or ADSs, such gain or loss will be capital gain or loss. Under current law, capital gains of non-corporate U.S. Holders derived with respect to capital assets held for more than one year are generally eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Capital gain or loss, if any, recognized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes. U.S. Holders are encouraged to consult their own tax advisors regarding the availability of the U.S. foreign tax credit in consideration of their particular circumstances.

If we were treated as a PRC resident enterprise for EIT Law purposes and PRC tax were imposed on any gain (see “—Taxation in the PRC” above), and if a U.S. Holder is eligible for the benefits of the U.S.-PRC Tax Treaty, the holder may be able to treat such gain as PRC source gain under the treaty for U.S. foreign tax credit purposes. A U.S. Holder will be eligible for U.S.-PRC Tax Treaty benefits if (for purposes of the treaty) such holder is a resident of the United States and satisfies the other requirements specified in the U.S.-PRC Tax Treaty. Because the determination of treaty benefit eligibility is fact-intensive and depends upon a holder’s particular circumstances, U.S. Holders should consult their tax advisors regarding U.S.-PRC Tax Treaty benefit eligibility. U.S. Holders are also encouraged to consult their own tax advisors regarding the tax consequences in the event PRC tax were to be imposed on a disposition of ordinary shares or ADSs, including the availability of the U.S. foreign tax credit and the ability and whether to treat any gain as PRC source gain for the purposes of the U.S. foreign tax credit in consideration of their particular circumstances.

Additional Tax on Net Investment Income

An additional 3.8% tax is imposed on the “net investment income” of certain U.S. citizens and resident aliens, and on the undistributed “net investment income” of certain estates and trusts. Among other items, “net investment income” would generally include dividends on and gains from the sale or other disposition of ordinary shares or ADSs. You should consult your own tax advisor regarding the application of this tax.

Passive Foreign Investment Company Considerations

Status as a PFIC

The rules governing PFICs can result in adverse tax consequences to U.S. Holders. We generally will be classified as a PFIC for U.S. federal income tax purposes if, for any taxable year, either: (1) 75% or more of our gross income consists of certain types of passive income, or (2) the average value (determined on a quarterly basis), of our assets that produce, or are held for the production of, passive income is 50% or more of the value of all of our assets.

Passive income generally includes dividends, interest, rents and royalties (other than certain rents and royalties derived in the active conduct of a trade or business), annuities and gains from assets that produce passive income. If a non-U.S. corporation owns at least 25% by value of the stock of another corporation, the non-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share of the other corporation’s income. Under this rule, we should be deemed to own a proportionate share of the assets and to have received a proportionate share of the income of our principal subsidiaries, including Hutchison Whampoa Guangzhou Baiyunshan Chinese Medicine Company Limited and Shanghai Hutchison Pharmaceuticals Limited, for purposes of the PFIC determination.

Additionally, if we are classified as a PFIC in any taxable year with respect to which a U.S. Holder owns ordinary shares or ADSs, we generally will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding taxable years, regardless of whether we continue to meet the tests described above, unless the U.S. Holder makes the “deemed sale election” described below. Furthermore, if we are treated as a PFIC, then one or more of our subsidiaries may also be treated as PFICs.

197

Based on certain estimates of our gross income and gross assets (which estimates are inherently imprecise) and the nature of our business, we do not believe that we are currently a PFIC. Notwithstanding the foregoing, the determination of whether we are a PFIC is made annually and depends on particular facts and circumstances (such as the valuation of our assets, including goodwill and other intangible assets) and also may be affected by the application of the PFIC rules, which are subject to differing interpretations. The fair market value of our assets is expected to depend, in part, upon (a) the market price of our ADSs, which is likely to fluctuate, and (b) the composition of our income and assets, which will be affected by how, and how quickly, we spend any cash that is raised in any financing transaction. In light of the foregoing, no assurance can be provided that we are not currently a PFIC or that we will not become a PFIC in any future taxable year. Prospective investors should consult their own tax advisors regarding our PFIC status.

U.S. federal income tax treatment of a shareholder of a PFIC

If we are classified as a PFIC for any taxable year during which a U.S. Holder owns ordinary shares or ADSs, the U.S. Holder, absent certain elections (including the mark-to-market and QEF elections described below), generally will be subject to adverse rules (regardless of whether we continue to be classified as a PFIC) with respect to (1) any “excess distributions” (generally, any distributions received by the U.S. Holder on its ordinary shares or ADSs in a taxable year that are greater than 125% of the average annual distributions received by the U.S. Holder in the three preceding taxable years or, if shorter, the U.S. Holder’s holding period) and (2) any gain realized on the sale or other disposition, including a pledge, of such ordinary shares or ADSs.

Under these rules (a) the excess distribution or gain will be allocated ratably over the U.S. Holder’s holding period, (b) the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which we are classified as a PFIC will be taxed as ordinary income and (c) the amount allocated to each other taxable year during the U.S. Holder’s holding period in which we were classified as a PFIC (i) will be subject to tax at the highest rate of tax in effect for the applicable category of taxpayer for that year and (ii) will be subject to an interest charge at a statutory rate with respect to the resulting tax attributable to each such other taxable year. In addition, non-corporate U.S. Holders will not be eligible for reduced rates of taxation on any dividends received from us if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year.

If we are classified as a PFIC, a U.S. Holder will generally be treated as owning a proportionate amount (by value) of stock or shares owned by us in any direct or indirect subsidiaries that are also PFICs and will be subject to similar adverse rules with respect to any distributions we receive from, and dispositions we make of, the stock or shares of such subsidiaries. U.S. Holders are urged to consult their tax advisors about the application of the PFIC rules to any of our subsidiaries.

If we are classified as a PFIC and then cease to be so classified, a U.S. Holder may make an election (a “deemed sale election”) to be treated for U.S. federal income tax purposes as having sold such U.S. Holder’s ordinary shares or ADSs on the last day of our taxable year during which we were a PFIC. A U.S. Holder that makes a deemed sale election would then cease to be treated as owning stock in a PFIC. However, gain recognized as a result of making the deemed sale election would be subject to the adverse rules described above and loss would not be recognized.

PFIC “mark-to-market” election

In certain circumstances, a holder of “marketable stock” of a PFIC can avoid certain of the adverse rules described above by making a timely mark-to-market election with respect to such stock. For purposes of these rules “marketable stock” is stock which is “regularly traded” (traded in greater than de minimis quantities on at least 15 days during each calendar quarter) on a “qualified exchange” or other market within the meaning of applicable U.S. Treasury Regulations. A “qualified exchange” includes a national securities exchange that is registered with the SEC.

198

A U.S. Holder that makes a timely mark-to-market election must include in gross income, as ordinary income, for each taxable year that we are a PFIC an amount equal to the excess, if any, of the fair market value of the U.S. Holder’s ordinary shares or ADSs that are “marketable stock” at the close of the taxable year over the U.S. Holder’s adjusted tax basis in such ordinary shares or ADSs. An electing U.S. Holder may also claim an ordinary loss deduction for the excess, if any, of the U.S. Holder’s adjusted tax basis in such ordinary shares or ADSs over their fair market value at the close of the taxable year, but this deduction is allowable only to the extent of any net mark-to-market gains previously included in income pursuant to the timely mark-to-market election. The adjusted tax basis of a U.S. Holder’s ordinary shares or ADSs with respect to which the timely mark-to-market election applies would be adjusted to reflect amounts included in gross income or allowed as a deduction because of such election. If a U.S. Holder makes an effective mark-to-market election with respect to our ordinary shares or ADSs, gains from an actual sale or other disposition of such ordinary shares or ADSs in a year in which we are a PFIC would be treated as ordinary income, and any losses incurred on such sale or other disposition would be treated as ordinary losses to the extent of any net mark-to-market gains previously included in income.

If we are classified as a PFIC for any taxable year in which a U.S. Holder owns ordinary shares or ADSs but before a timely mark-to-market election is made, the adverse PFIC rules described above will apply to any mark-to-market gain recognized in the year the election is made. Otherwise, a timely mark-to-market election will be effective for the taxable year for which the election is made and all subsequent taxable years unless the ordinary shares or ADSs are no longer regularly traded on a qualified exchange or the IRS consents to the revocation of the election. Our ADSs are listed on the Nasdaq Global Select Market, which is a qualified exchange or other market for purposes of the mark-to-market election. Consequently, if the ADSs continue to be so listed, and are “regularly traded” for purposes of these rules (for which no assurance can be given) we expect that the mark-to-market election would be available to a U.S. Holder with respect to our ADSs.

A mark-to-market election is not permitted for the shares of any of our subsidiaries that are also classified as PFICs. Prospective investors should consult their own tax advisors regarding the availability of, and the procedure for, and the effect of making, a mark-to-market election, and whether making the election would be advisable, including in light of their particular circumstances.

PFIC “QEF” election

In some cases, a shareholder of a PFIC can avoid the interest charge and the other adverse PFIC tax consequences described above by obtaining certain information from the PFIC and by making a timely QEF election to be taxed currently on its share of the PFIC’s undistributed income. We do not, however, expect to provide the information regarding our income that would be necessary in order for a U.S. Holder to make a timely QEF election if we were classified as a PFIC.

PFIC information reporting requirements

If we are classified as a PFIC in any year with respect to a U.S. Holder, such U.S. Holder will be required to file an annual information return on IRS Form 8621 regarding distributions received on, and any gain realized on the disposition of, our ordinary shares and ADSs, and certain U.S. Holders will be required to file an annual information return (also on IRS Form 8621) relating to their ownership interest.

NO ASSURANCE CAN BE GIVEN THAT WE ARE NOT CURRENTLY A PFIC OR THAT WE WILL NOT BECOME A PFIC IN THE FUTURE. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE OPERATION OF THE PFIC RULES AND RELATED REPORTING REQUIREMENTS IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE ADVISABILITY AND EFFECTS OF MAKING ANY ELECTION THAT MAY BE AVAILABLE.

U.S. Backup Withholding and Information Reporting and Filing Requirements

Backup withholding and information reporting requirements may apply to distributions on, and proceeds from the sale or disposition of, ordinary shares and ADSs that are held by U.S. Holders. The payor will be required to withhold tax (currently at a rate of 24%) on such payments made within the United States, or by a U.S. payor or a U.S. intermediary (and certain subsidiaries thereof) to a U.S. Holder, other than an exempt recipient, if the U.S. Holder is not otherwise exempt and:

● the holder fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number;

199

● the holder furnishes an incorrect taxpayer identification number;

● the applicable withholding agent is notified by the IRS that the holder previously failed to properly report payments of interest or dividends; or

● the holder fails to certify under penalties of perjury that the holder has furnished a correct taxpayer identification number and that the IRS has not notified the holder that the holder is subject to backup withholding.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability (if any) or refunded provided the required information is furnished to the IRS in a timely manner. U.S. Holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Certain U.S. Holders of specified foreign financial assets with an aggregate value in excess of the applicable dollar threshold are required to report information relating to their holding of ordinary shares or ADSs, subject to certain exceptions (including an exception for shares held in accounts maintained by certain financial institutions) with their tax returns for each year in which they hold such interests. U.S. Holders should consult their own tax advisors regarding the information reporting obligations that may arise from their acquisition, ownership or disposition of our ordinary shares or ADSs.

THE ABOVE DISCUSSION DOES NOT COVER ALL TAX MATTERS THAT MAY BE OF IMPORTANCE TO A PARTICULAR INVESTOR. PROSPECTIVE INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISORS ABOUT THE TAX CONSEQUENCES OF AN INVESTMENT IN OUR ORDINARY SHARES OR ADSs.

We are subject to the informational requirements of the Exchange Act and are required to file reports and other information with the SEC. Shareholders may access our reports and other information filed with the SEC by viewing them on the SEC’s website, at www.sec.gov. We also make available on our website’s investor relations page, free of charge, our annual report and the text of our reports on Form 6-K, including any amendments to these reports, as well as certain other SEC filings, as soon as reasonably practicable after they are electronically filed with or furnished to the SEC. The address for our investor relations page is www.chi-med.com/investors. The information contained on our website is not incorporated by reference in this annual report.

We are a “foreign private issuer” as such term is defined in Rule 405 under the Securities Act, and are not subject to the same requirements that are imposed upon U.S. domestic issuers by the SEC. Under the Exchange Act, we are subject to reporting obligations that, in certain respects, are less detailed and less frequent than those of U.S. domestic reporting companies. As a result, we do not file the same reports that a U.S. domestic issuer would file with the SEC, although we are required to file or furnish to the SEC the continuous disclosure documents that we are required to file on the AIM market of the London Stock Exchange.

We will furnish Deutsche Bank Trust Company Americas, the depositary of our ADSs, with our annual reports, which will include a review of operation and annual audited consolidated financial statements prepared in conformity with U.S. GAAP, and all notices of shareholders’ meetings and other reports and communications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available to holders of ADSs and, upon our requests, will mail to all record holders of ADSs the information contained in any notice of a shareholders’ meeting received by the depositary from us.

Fees and charges our ADS holders may have to pay

ADS holders will be required to pay the following service fees to Deutsche Bank Trust Company America, the depositary of our ADS program, and certain taxes and governmental charges (in addition to any applicable fees, expenses, taxes and other governmental charges payable on the deposited securities represented by ADSs):

Service	Fees
●     To any person to which ADSs are issued or to any person to which a distribution is made in respect of ADS distributions pursuant to stock dividends or other free distributions of stock, bonus distributions, stock splits or other distributions (except where converted to cash)	Up to $0.05 per ADS issued
●     Cancellation or withdrawal of ADSs, including the case of termination of the deposit agreement	Up to $0.05 per ADS cancelled
●     Distribution of cash dividends	Up to $0.05 per ADS held
●     Distribution of cash entitlements (other than cash dividends) and/or cash proceeds from the sale of rights, securities and other entitlements	Up to $0.05 per ADS held
●     Distribution of ADSs pursuant to exercise of rights	Up to $0.05 per ADS held
●     Depositary services	Up to $0.05 per ADS held on the applicable record date(s) established by the depositary bank (an annual fee)

ADS holders will also be responsible to pay certain fees and expenses incurred by the depositary bank and certain taxes and governmental charges (in addition to any applicable fees, expenses, taxes and other governmental charges payable on the deposited securities represented by any of your ADSs) such as:

● Fees for the transfer and registration of ordinary shares charged by the registrar and transfer agent for the ordinary shares in the Cayman Islands (i.e., upon deposit and withdrawal of ordinary shares).

● Expenses incurred for converting foreign currency into U.S. dollars.

● Expenses for cable, telex and fax transmissions and for delivery of securities.

● Taxes and duties upon the transfer of securities, including any applicable stamp duties, any stock transfer charges or withholding taxes (i.e., when ordinary shares are deposited or withdrawn from deposit).

201

● Fees and expenses incurred in connection with the delivery or servicing of ordinary shares on deposit.

● Fees and expenses incurred in connection with complying with exchange control regulations and other regulatory requirements applicable to ordinary shares, ordinary shares deposited securities, ADSs and ADRs.

● Any applicable fees and penalties thereon.

The depositary fees payable upon the issuance and cancellation of ADSs are typically paid to the depositary bank by the brokers (on behalf of their clients) receiving the newly issued ADSs from the depositary bank and by the brokers (on behalf of their clients) delivering the ADSs to the depositary bank for cancellation. The brokers in turn charge these fees to their clients. Depositary fees payable in connection with distributions of cash or securities to ADS holders and the depositary services fee are charged by the depositary bank to the holders of record of ADSs as of the applicable ADS record date.

The depositary fees payable for cash distributions are generally deducted from the cash being distributed or by selling a portion of distributable property to pay the fees. In the case of distributions other than cash (i.e., share dividends, rights), the depositary bank charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether certificated or uncertificated in direct registration), the depositary bank sends invoices to the applicable record date ADS holders. In the case of ADSs held in brokerage and custodian accounts (via DTC), the depositary bank generally collects its fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding ADSs in their DTC accounts. The brokers and custodians who hold their clients’ ADSs in DTC accounts in turn charge their clients’ accounts the amount of the fees paid to the depositary banks.

In the event of refusal to pay the depositary fees, the depositary bank may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder.

The depositary has agreed to pay certain amounts to us in exchange for its appointment as depositary. We may use these funds towards our expenses relating to the establishment and maintenance of the ADR program, including investor relations expenses, or otherwise as we see fit. In 2018, we did not collect any reimbursements from the depositary for expenses related to the administration and maintenance of the facility.

ITEM 15. CONTROLS AND PROCEDURES

A.    Evaluation of Disclosure Controls and Procedures.

As required by Rule 13a-15 under the Exchange Act, management, including our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Disclosure controls and procedures refer to controls and other procedures designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in our reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding our required disclosure. Based on such evaluation, our management has concluded that, as of December 31, 2019, our disclosure controls and procedures were effective.

B.    Management’s Annual Report on Internal Control over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements in accordance with U.S. GAAP and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of a company’s assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that a company’s receipts and expenditures are being made only in accordance with authorizations of a company’s management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of a company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness of our internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, with the participation of our chief executive officer and chief financial officer, has assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 Framework). Based on this assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2019.

As permitted by Nasdaq, in lieu of the Nasdaq corporate governance rules, but subject to certain exceptions, we may follow the practices of our home country which for the purpose of such rules is the Cayman Islands. Certain corporate governance practices in the Cayman Islands may differ significantly from corporate governance listing standards as, except for general fiduciary duties and duties of care, Cayman Islands law has no corporate governance regime which prescribes specific corporate governance standards. For example, we follow Cayman Islands corporate governance practices in lieu of the corporate governance requirements of the Nasdaq Global Select Market in respect of the following:

(i) the majority independent director requirement under Section 5605(b)(1) of the Nasdaq listing rules,

(ii) the requirement under Section 5605(d) of the Nasdaq listing rules that a remuneration committee comprised solely of independent directors governed by a remuneration committee charter oversee executive compensation, and

(iii) the requirement under Section 5605(e) of the Nasdaq listing rules that director nominees be selected or recommended for selection by either a majority of the independent directors or a nominations committee comprised solely of independent directors.

Cayman Islands law does not impose a requirement that our board of directors consist of a majority of independent directors. Nor does Cayman Islands law impose specific requirements on the establishment of a remuneration committee or nominating committee or nominating process. We voluntarily comply with certain principles of the U.K. Corporate Governance Code. See Item 6.C. “Board Practice—U.K. Corporate Governance Code” for more details.

The consolidated financial statements of Nutrition Science Partners relating to the period ended December 9, 2019 included herein are not the Hong Kong statutory annual financial statements of Nutrition Science Partners for the year ended December 31, 2019.

Nutrition Science Partners’ auditor has separately reported on those financial statements. The auditor’s report was unqualified; did not include a reference to any matters to which the auditor drew attention by way of emphasis without qualifying its report; and did not contain a statement under sections 406(2), 407(2) or (3) of the Hong Kong Companies Ordinance Cap. 622.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Hutchison China MediTech Limited

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Hutchison China MediTech Limited and its subsidiaries (the “Company”) as of December 31, 2019 and 2018, and the related consolidated statements of operations, of comprehensive loss, of changes in shareholders’ equity and of cash flows for each of the three years in the period ended December 31, 2019, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 15 of Form 20-F. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

F-2

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Principal versus agent assessment on revenue recognition

As described in Noted 3 and Note 19 to the consolidated financial statements, net service income arising from the net fee-for-service revenue model in the Company’s Commercial Platform of US$2.6 million was recorded for the year ended December 31, 2019, representing 1.3% of total revenue of the Company. Management assessed the principal versus agent considerations under Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), in particular the control of the goods before delivery to the customers and inventory risk, and concluded that the Company is an agent under the relevant distribution arrangements in certain cities in the People’s Republic of China (the “PRC”).

The principal considerations for our determination that performing procedures relating to the principal versus agent assessment on revenue recognition is a critical audit matter are (i) there was significant judgment by management when determining whether the Company is an agent in the relevant distribution arrangements, which in turn led to a high degree of auditor judgement and effort in performing procedures to evaluate the analysis made by management and (ii) the gross versus net impact to the presentation of the revenue in the consolidated statement of operation is material.

Addressing the matter involved performing procedures and evaluating audit evidence, in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the management’s review process on the assessment on principal versus agent analysis and the quantification of service income recorded in the consolidated statement of operation. The procedures also included, among others, reading the distribution agreements entered with the relevant counterparties, evaluating management’s assessment on the principal versus agent analysis and assessing the appropriateness of the financial statements presentation of revenue.

Assessment on the valuation of Seroquel-related balances

As described in Note 27 to the consolidated financial statements, Luye Pharma Hong Kong Ltd. (“Luye”) issued a notice to the Company during the year purporting to terminate a distribution agreement that granted the Company exclusive commercial rights to Seroquel in the PRC (the “Distribution Agreement”), on the basis of failure to meet a pre-specific target. As disclosed by management, the Company disagreed with this assertion and believed that Luye had no basis for termination. Accordingly, the Company commenced legal proceedings in 2019 in order to compel Luye to comply with its obligations under the Distribution Agreement, or alternatively compensate the Company’s damages. The legal proceedings are still in progress. Management has assessed and concluded that no adjustment is required for all Seroquel-related balances as at December 31, 2019, including accounts receivable, long-term prepayment, accounts payable and other payables of US$1.1 million (asset), US$1.1 million (asset), US$0.9 million (liability) and US$1.1 million (liability), respectively.

The principal considerations for our determination that performing procedures relating to the assessment on the valuation of Seroquel-related balances pursuant to the termination notice from Luye is a critical audit matter are that there was significant judgment by management when determining whether the Company is legally entitled to continue the Seroquel distribution agreement, which in turn led to a high degree of auditor judgment and effort in evaluating management’s assessment associated with the purported termination notice that Luye issued to the Company.

F-3

Addressing the matter involved performing procedures and evaluating audit evidence, in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s assessment on the valuation of Seroquel-related balances, including controls over determining whether the Company is legally entitled to continue the Seroquel distribution agreement, as well as financial statement disclosures. These procedures also included, among others, discussing with management on the latest negotiation and the litigation status; obtaining and evaluating the legal opinion from the external legal counsel and correspondence between the Company and Luye to support assumptions in the assessment; obtaining and evaluating the letters of audit inquiry with external legal counsel; evaluating the competence, capability and objectivity of the external legal counsel; evaluating the reasonableness of management’s assessment regarding whether an unfavorable outcome is reasonably possible or probable and reasonably estimable; performing subsequent event procedures for any newly available information after year end; and evaluating the sufficiency of the Company’s disclosures on this matter.

The Company’s ordinary shares are listed on the AIM market of the London Stock Exchange, and its American depositary shares (“ADS”), each representing five ordinary shares, are traded on the Nasdaq Global Select Market.

Liquidity

As at December 31, 2019, the Group had accumulated losses of US$289,734,000, primarily due to its spending in drug research and development (“Drug R&D”) activities. The Group regularly monitors current and expected liquidity requirements to ensure that it maintains sufficient cash balances and adequate credit facilities to meet its liquidity requirements in the short and long term. As at December 31, 2019, the Group had cash and cash equivalents of US$121,157,000, short-term investments of US$96,011,000 and unutilized bank borrowing facilities of US$119,359,000. Short-term investments comprised of bank deposits maturing over three months. The Group’s operating plan includes the continued receipt of dividends from certain of its equity investees.

Notes:

(a) In November 2019, a subsidiary of the Group transferred its 51% shareholding in HSPL to HMPL. Afterwards, the effective equity interest of the Group in HSPL changed to 50.87% as at December 31, 2019.

(b) HHOL and HHOGZL are regarded as subsidiaries of the Company, as while both shareholders of these subsidiaries have equal representation at their respective boards, in the event of a deadlock, the Group has a casting vote and is therefore able to unilaterally control the financial and operating policies of HHOL and HHOGZL.

(c) As at December 31, 2018, the 50% equity interest in NSPL was held by a 99.75% owned subsidiary of the Group. The effective equity interest of the Group in NSPL was therefore 49.88%. In December 2019, the Group acquired the remaining 50% shareholding in NSPL from the equity investee partner for a consideration of approximately US$8.1 million. Afterwards, the effective equity interest of the Group in NSPL changed to 99.75% as at December 31, 2019.

(d) The 50% equity interest in HBYS is held by an 80% owned subsidiary of the Group. The effective equity interest of the Group in HBYS is therefore 40% for the years presented.

3. Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements reflect the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. Investments in equity investees over which the Group has significant influence are accounted for using the equity method. All inter-company balances and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Additionally, estimates are used in determining items such as useful lives of property, plant and equipment, write-down of inventories, allowance for doubtful accounts, share-based compensation, impairments of long-lived assets, impairment of other intangible asset and goodwill, income tax expenses, tax valuation allowances, revenues and cost accruals from research and development projects. Actual results could differ from those estimates.

Foreign Currency Translation

The Company’s presentation currency is the U.S. dollar (“US$”). The financial statements of the Company and its subsidiaries with a functional currency other than the US$ have been translated into the Company’s presentation currency. All assets and liabilities of the subsidiaries are translated using year-end exchange rates and revenues and expenses are translated at average exchange rates for the year. Translation adjustments are reflected in accumulated other comprehensive (loss)/income in shareholders’ equity.

Net foreign currency exchange gains of US$246,000 and net foreign exchanges losses of US$233,000 and US$316,000 were recorded in other income and other expense in the consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017 respectively.

Cash and Cash Equivalents

The Group considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of cash on hand and bank deposits and are stated at cost, which approximates fair value.

Short-term Investments

Short-term investments include deposits placed with banks with original maturities of more than three months but less than one year.

Concentration of Credit Risk

Financial instruments that potentially expose the Group to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, accounts receivable, other receivables and amounts due from related parties.

The Group places substantially all of its cash and cash equivalents and short-term investments in major financial institutions, which management believes are of high credit quality. The Group has a practice to limit the amount of credit exposure to any particular financial institution.

The Group has no significant concentration of credit risk. The Group has policies in place to ensure that sales are made to customers with an appropriate credit history and the Group performs periodic credit evaluations of its customers. Normally the Group does not require collateral from trade debtors.

F-12

Foreign Currency Risk

The Group’s operating transactions and its assets and liabilities  in the PRC are mainly denominated in Renminbi (“RMB”), which is not freely convertible into foreign currencies. The Group’s cash and cash equivalents denominated in RMB are subject to government controls. The value of the RMB is subject to fluctuations from central government policy changes and international economic and political developments that affect the supply and demand of RMB in the foreign exchange market. In the PRC, certain foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China (the “PBOC”). Remittances in currencies other than RMB by the Group in the PRC must be processed through the PBOC or other PRC foreign exchange regulatory bodies which require certain supporting documentation in order to complete the remittance.

Fair Value of Financial Instruments

The fair value of financial instruments that are measured at fair value is determined according to a fair value hierarchy that prioritizes the inputs and assumptions used, and the valuation techniques used. The three levels of the fair value hierarchy are described as follows:

Level 1	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2	Inputs are quoted prices for similar assets or liabilities in active markets; or quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
Level 3	Inputs are unobservable inputs based on the Group’s assumptions and valuation techniques used to measure assets or liabilities at fair value. The inputs require significant management judgment or estimation.

The assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels.

The fair value of assets and liabilities is established using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, and a fair value hierarchy is established based on the inputs used to measure fair value.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from customers based on their outstanding invoices. Management reviews accounts receivable regularly to determine if any receivable will potentially be uncollectible. Estimates are used to determine the amount of allowance for doubtful accounts necessary to reduce accounts receivable to its estimated net realizable value. The amount of the allowance for doubtful accounts is recognized in the consolidated statements of operations.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. A provision for excess and obsolete inventory will be made based primarily on forecasts of product demand and production requirements. The excess balance determined by this analysis becomes the basis for excess inventory charge and the written-down value of the inventory becomes its cost. Written-down inventory is not written up if market conditions improve.

F-13

Property, Plant and Equipment

Property, plant and equipment consist of buildings, leasehold improvements, plant and equipment, furniture and fixtures, other equipment and motor vehicles. Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets.

Buildings	20 years
Plant and equipment	5-10 years
Furniture and fixtures, other equipment and motor vehicles	4-5 years
Leasehold improvements	Shorter of (a) 5 years or (b) remaining term of lease

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the consolidated statements of operations in the year of disposition. Additions and improvements that extend the useful life of an asset are capitalized. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

The Group evaluates the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets. The Group evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. If such indicators exist, the first step of the impairment test is performed to assess if the carrying value of the net assets exceeds the undiscounted cash flows of the assets. If yes, the second step of the impairment test is performed in order to determine if the carrying value of the net assets exceeds the fair value. If yes, impairment is recognized for the excess.

Leasehold Land

Leasehold land represents fees paid to acquire the right to use the land on which various plants and buildings are situated for a specified period of time from the date the respective right was granted and are stated at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the lease period of 50 years.

Goodwill

Goodwill represents the excess of the purchase price plus fair value of non-controlling interests over the fair value of identifiable assets and liabilities acquired. Goodwill is not amortized, but is tested for impairment at the reporting unit level on at least an annual basis or when an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When performing an evaluation of goodwill impairment, the Group has the option to first assess qualitative factors, such as significant events and changes to expectations and activities that may have occurred since the last impairment evaluation, to determine if it is more likely than not that goodwill might be impaired. If as a result of the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the quantitative fair value test is performed to determine if the fair value of the reporting unit exceeds its carrying value.

Other Intangible Assets

Other intangible assets with finite useful lives are carried at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the estimated useful lives of the assets.

Borrowings

Borrowings are recognized initially at fair value, net of debt issuance costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of debt issuance costs) and the redemption value is recognized in the consolidated statements of operations over the period of the borrowings using the effective interest method.

F-14

Ordinary Shares

The Company’s ordinary shares are stated at par value of US$0.10 per ordinary share. The difference between the consideration received, net of issuance cost, and the par value is recorded in additional paid-in capital.

Treasury Shares

The Group accounts for treasury shares under the cost method. The treasury shares are purchased for the purpose of the LTIP and held by a trustee appointed by the Group (the “Trustee”) prior to vesting.

Share-Based Compensation

Share options

The Group recognizes share-based compensation expense on share options granted to employees and directors based on their estimated grant date fair value using the Polynomial model. This Polynomial pricing model uses various inputs to measure fair value, including estimated market value of the Company’s underlying ordinary shares at the grant date, contractual terms, estimated volatility, risk-free interest rates and expected dividend yields. The Group recognizes share-based compensation expense in the consolidated statements of operations on a graded vesting basis over the requisite service period, and accounts for forfeitures as they occur.

Share options are classified as equity-settled awards. Share-based compensation expense, when recognized, is charged to the consolidated statements of operations with the corresponding entry to additional paid-in capital.

LTIP

The Group recognizes the share-based compensation expense on the LTIP awards based on a fixed or determinable monetary amount on a straight-line basis for each annual tranche awarded over the requisite period. For LTIP awards with performance targets, prior to their determination date, the amount of LTIP awards that is expected to vest takes into consideration the achievement of the performance conditions and the extent to which the performance conditions are likely to be met. Performance conditions vary by awards, including targets for shareholder returns, free cash flows, revenues, net profit after taxes and/or the achievement of clinical and regulatory milestones.

These LTIP awards are classified as liability-settled awards before the determination date (i.e. the date when the achievement of any performance conditions are known), as they settle in a variable number of shares based on a determinable monetary amount, which is determined upon the actual achievement of performance targets. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management’s assessment of the achievement of the performance targets has been assigned to calculate the amount to be recognized as an expense over the requisite period.

After the determination date or if the LTIP awards have no performance conditions, the LTIP awards are classified as equity-settled awards. If the performance target is achieved, the Group will pay the determined monetary amount to the Trustee to purchase ordinary shares of the Company or the equivalent ADS. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no ordinary shares or ADS of the Company will be purchased and the amount previously recorded in the liability will be reversed and included in the consolidated statements of operations.

Defined Contribution Plans

The Group’s subsidiaries in the PRC participate in a government-mandated multi-employer defined contribution plan pursuant to which certain retirement, medical and other welfare benefits are provided to employees. The relevant labor regulations require the Group’s subsidiaries in the PRC to pay the local labor and social welfare authority’s monthly contributions at a stated contribution rate based on the monthly basic compensation of qualified employees. The relevant local labor and social welfare authorities are responsible for meeting all retirement benefits obligations and the Group’s subsidiaries in the PRC have no further commitments beyond their monthly contributions. The contributions to the plan are expensed as incurred.

F-15

The Group also makes payments to other defined contribution plans for the benefit of employees employed by subsidiaries outside the PRC. The defined contribution plans are generally funded by the relevant companies and by payments from employees.

The Group’s contributions to defined contribution plans for the years ended December 31, 2019, 2018 and 2017 amounted to US$3,479,000, US$2,878,000 and US$2,092,000 respectively.

Revenue Recognition

Summary of impact of applying Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (Topic 606) (“ASC 606”)

The Group applied ASC 606 to all contracts at the date of initial application of January 1, 2018. As a result, the Group has changed its accounting policy for revenue recognition as detailed below. The Group applied ASC 606 using the modified retrospective method by recognizing the cumulative effect as an adjustment to opening accumulated losses at January 1, 2018. The comparative information prior to January 1, 2018 has not been adjusted and continues to be reported under ASC 605, Revenue Recognition (Topic 605) (“ASC 605”).

The Group assessed its license and collaboration contracts under ASC 606. Refer to Note 19. As a result of this assessment, the Group recorded an aggregate US$1.1 million deferral of revenue as a cumulative adjustment to opening accumulated losses upon adoption.

For sales of goods and services, the Group applied a portfolio approach to aggregate contracts into portfolios whose performance obligations do not differ materially from each other. In its assessment of each portfolio, the Group assessed the contracts under the new five-step model under ASC 606 and determined there was no significant impact to the timing or amount of revenue recognition under the new guidance.

Under the Group’s previous accounting policy, deferred revenue comprised deferred upfront payments from the Group’s license and collaboration contracts. Under ASC 606, advance payments from customers preceding an entity’s performance are considered contract liabilities; therefore, advance payments from customers from the Group’s Commercial Platform have been reclassified from other payables, accruals and advance receipts to deferred revenue. Expected rebates for sales of goods remain in other payables, accruals and advance receipts.

F-16

The following tables summarize the impact of adopting ASC 606 on the Group’s consolidated financial statements as at and for the year ended December 31, 2018, as compared to the amounts as if applying ASC 605:

Accounting policy—ASC 606

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Group from a customer, are also excluded from revenue. The Group recognizes revenue when it satisfies a performance obligation by transferring control over a good, service or license to a customer.

Nature of goods and services

The following is a description of principal activities, separated by reportable segments, from which the Company generates its revenue:

(i)    Innovation Platform

The Innovation Platform reportable segment principally generates revenue from license and collaboration contracts. The license and collaboration contracts generally contain multiple performance obligations including (1) the license to the commercialization rights of a drug compound and (2) the research and development services for each specified treatment indication, which are accounted for separately if they are distinct, i.e. if a product or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer.

The transaction price generally includes fixed and variable consideration in the form of upfront payment, research and development cost reimbursements, contingent milestone payments and sales-based royalties. Contingent milestone payments are not included in the transaction price until it becomes probable that a significant reversal of revenue will not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation is based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. The Group estimates the standalone selling prices based on the income approach. Control of the license to the drug compounds transfers at the inception date of the collaboration agreements and consequently, amounts allocated to this performance obligation are generally recognized at a point in time. Conversely, research and development services for each specified indication are performed over time and amounts allocated to these performance obligations are generally recognized over time using cost inputs as a measure of progress. The Group has determined that research and development expenses provide an appropriate depiction of measure of progress for the research and development services. Changes to estimated cost inputs may result in a cumulative catch-up adjustment. Royalty revenues are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception, and are included in Commercial Platform revenues.

Deferred revenue is recognized if allocated consideration is received in advance of the Group rendering research and development services. Accounts receivable is recognized based on the terms of the contract and when the Group has an unconditional right to bill the customer, which is generally when research and development services are rendered.

(ii)    Commercial Platform

The Commercial Platform reportable segment principally generates revenue from (1) sales of goods, which are the manufacture or purchase and distribution of products including a prescription drug product developed by the Innovation Platform and other consumer health products, (2) royalty revenues from license and collaboration contracts and (3) sales of services, which are the provision of sales, distribution and marketing services to pharmaceutical manufacturers. The Group evaluates whether it is the principal or agent for these contracts, which include prescription drug products and consumer health products. Where the Group obtains control of the goods for distribution, it is the principal (i.e. recognizes sales of goods on a gross basis). Where the Group does not obtain control of the goods for distribution, it is the agent (i.e. recognizes provision of services on a net basis). Control is primarily evidenced by taking physical possession and inventory risk of the goods.

Revenue from sales of goods is recognized when the customer takes possession of the goods. This usually occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

F-18

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, the Group recognizes revenue from provision of services based on amounts that can be invoiced to the customer.

Deferred revenue is recognized if consideration is received in advance of transferring control of the goods or rendering of services. Accounts receivable is recognized if the Group has an unconditional right to bill the customer, which is generally when the customer takes possession of the goods or services are rendered. Payment terms differ by subsidiary and customer, but generally range from 45 to 180 days from the invoice date.

Prior accounting policy—ASC 605

Sales

Revenue from sales of goods in the Commercial Platform segment are recognized when goods are delivered and title passes to the customer and there are no further obligations to the customer. Recognition of revenue also requires reasonable assurance of collection of sales proceeds and completion of all performance obligations. Sales discounts are issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from sales of services in the Commercial Platform segment are recognized based on amounts that can be invoiced to the customer. The amount that can be invoiced corresponds directly with the value to the customer for performance completed to date.

Revenues from research and development projects

The Group recognizes revenue for the performance of services when each of the following four criteria are met: (i) persuasive evidence of an arrangement exists; (ii) services are rendered; (iii) the sales price is fixed or determinable; and (iv) collectability is reasonably assured.

The Group follows ASC 605-25, Revenue Recognition—Multiple-Element Arrangements and ASC 808, Collaborative Arrangements, if applicable, to determine the recognition of revenue under the Group’s license and collaborative research, development and commercialization agreements. The terms of these agreements generally contain multiple elements, or deliverables, which may include (i) licenses to the Group’s intellectual property, (ii) materials and technology, (iii) clinical supply, and/or (iv) participation in joint research or joint steering committees. The payments the Group may receive under these arrangements typically include one or more of the following: non-refundable, upfront license fees; funding of research and/or development efforts; amounts due upon the achievement of specified milestones; and/or royalties on future product sales.

ASC 605-25 provides guidance relating to the separability of deliverables included in an arrangement into different units of accounting and the allocation of arrangement consideration to the units of accounting. The evaluation of multiple-element arrangements requires management to make judgments about (i) the identification of deliverables, (ii) whether such deliverables are separable from the other aspects of the contractual relationship, (iii) the estimated selling price of each deliverable, and (iv) the expected period of performance for each deliverable.

F-19

To determine the units of accounting under a multiple-element arrangement, management evaluates certain separation criteria, including whether the deliverables have stand-alone value, based on the relevant facts and circumstances for each arrangement. Management then estimates the selling price for each unit of accounting and allocates the arrangement consideration to each unit utilizing the relative selling price method. The Group determines the estimated selling price for deliverables within each agreement using vendor-specific objective evidence (“VSOE”) of selling price, if available, or third party evidence of selling price if VSOE is not available, or the Group’s best estimate of selling price, if neither VSOE nor third party evidence is available. Determining the best estimate of selling price for a deliverable requires significant judgment. The Group typically uses its best estimate of a selling price to estimate the selling price for licenses to development work, since it often does not have VSOE or third party evidence of selling price for these deliverables. In those circumstances where the Group applies its best estimate of selling price to determine the estimated selling price of a license to development work, it considers market conditions as well as entity-specific factors, including those factors contemplated in negotiating the agreements as well as internally developed estimates that include assumptions related to the market opportunity, estimated development costs, probability of success and the time needed to commercialize a product candidate pursuant to the license. In validating its best estimate of selling price, the Group evaluates whether changes in the key assumptions used to determine its best estimate of selling price will have a significant effect on the allocation of arrangement consideration between deliverables. The Group recognizes consideration allocated to an individual element when all other revenue recognition criteria are met for that element.

The allocated consideration for each unit of accounting is recognized over the related obligation period in accordance with the applicable revenue recognition criteria.

If there are deliverables in an arrangement that are not separable from other aspects of the contractual relationship, they are treated as a combined unit of accounting, with the allocated revenue for the combined unit recognized in a manner consistent with the revenue recognition applicable to the final deliverable in the combined unit. Payments received prior to satisfying the relevant revenue recognition criteria are recorded as unearned revenue in the accompanying balance sheets and recognized as revenue when the related revenue recognition criteria are met.

The Group typically receives non-refundable, upfront payments when licensing the Group’s intellectual property, which often occurs in conjunction with a research and development agreement. If management believes that the license to the Group’s intellectual property has stand-alone value, the Group generally recognizes revenue attributed to the license upon delivery provided that there are no future performance requirements for use of the license. When management believes that the license to the Group’s intellectual property does not have stand-alone value, the Group will recognize revenue attributed to the license ratably over the contractual or estimated performance period. For payments payable on achievement of milestones that do not meet all of the conditions to be considered substantive, the Group recognizes a portion of the payment as revenue when the specific milestone is achieved, and the contingency is removed. Other contingent event-based payments for which payment is either contingent solely upon the passage of time or the result of a collaborator’s performance are recognized when earned. The Group’s collaboration and license agreements generally include contingent milestone payments related to specified pre-clinical research and development milestones, clinical development milestones, regulatory milestones and sales-based milestones. Pre-clinical research and development milestones are typically payable upon the selection of a compound candidate for the next stage of research and development. Clinical development milestones are typically payable when a product candidate initiates or advances in clinical trial phases or achieves defined clinical events such as proof-of-concept. Regulatory milestones are typically payable upon submission for marketing approval with regulatory authorities or upon receipt of actual marketing approvals for a compound, approvals for additional indications, or upon the first commercial sale. Sales-based milestones are typically payable when annual sales reach specified levels.

At the inception of each arrangement that includes milestone payments, the Group evaluates whether each milestone is substantive and at risk to both parties on the basis of the contingent nature of the milestone. This evaluation includes an assessment of whether (a) the consideration is commensurate with either (i) the entity’s performance to achieve the milestone or (ii) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone; (b) the consideration relates solely to past performance; and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Group evaluates factors such as the scientific, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required to achieve the respective milestone and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment.

F-20

Research and Development Expenses

Research and development expenses consist primarily of salaries and benefits, share-based compensation, materials and supplies, contracted research, consulting arrangements and other expenses incurred to sustain the Group’s research and development programs. Research and development costs are expensed as incurred.

Government Incentives

Incentives from governments are recognized at their fair values. Government incentives that are received in advance are deferred and recognized in the consolidated statements of operations over the period necessary to match them with the costs that they are intended to compensate. Government incentives in relation to the achievement of stages of research and development projects are recognized in the consolidated statements of operations when amounts have been received and all attached conditions have been met. Non-refundable incentives received without any further obligations or conditions attached are recognized immediately in the consolidated statements of operations.

Leases

Summary of impact of applying ASC 842

The Group applied ASC 842 to its various leases at the date of initial application of January 1, 2019. As a result, the Group has changed its accounting policy for leases as detailed below. The core principle of ASC 842 is that a lessee should recognize the assets and liabilities that arise from leases. Therefore, the Group recognizes in the consolidated balance sheets liabilities to make lease payments (the lease liabilities) and right-of-use assets representing its right to use the underlying assets for their lease terms. The Group applied ASC 842 using the optional transition method by recognizing the cumulative effect as an adjustment to opening accumulated losses as at January 1, 2019. The comparative information prior to January 1, 2019 has not been adjusted and continues to be reported under ASC 840, Leases (“ASC 840”).

The Group assessed lease agreements as at January 1, 2019 under ASC 842, except for short-term leases. The Group elected the short-term lease exception for leases with a term of 12 months or less and recognizes lease expenses for such leases on a straight-line basis over the lease term and does not recognize right-of-use assets or lease liabilities accordingly. As a result of this assessment, the Group recorded an aggregate US$0.7 million in additional lease expenses as a cumulative adjustment to opening accumulated losses upon adoption. Additionally, the Group recognized right-of-use assets and lease liabilities of US$5.7 million and US$6.4 million respectively as at January 1, 2019.

The lease liabilities were measured at the present value of the remaining lease payments, discounted using the lessees’ incremental borrowing rate as at January 1, 2019. The Group’s weighted average incremental borrowing rate applied on January 1, 2019 was 3.97% per annum.

A reconciliation of the Group’s reported operating lease commitments as at December 31, 2018 and the Group’s lease liabilities recognized upon adoption of ASC 842 as at January 1, 2019 is as follows:

	(in US$’000)
Operating lease commitments as at December 31, 2018 (note (a))	8,835
Less: Leases not commenced as at January 1, 2019	(3,676)
Less: Short‑term leases	(5)
Add: Adjustment as a result of the treatment for a termination option (note (b))	1,409
Less: Discount under the lessees’ incremental borrowing rate as at January 1, 2019	(206)
Lease liabilities recognized as at January 1, 2019	6,357

F-21

Notes:

(a) Future aggregate minimum payments under non-cancellable operating leases under ASC 840 were as follows:

	December 31,
	2018
	(in US$’000)
Not later than 1 year	3,026
Between 1 to 2 years	2,735
Between 2 to 3 years	1,056
Between 3 to 4 years	882
Between 4 to 5 years	810
Later than 5 years	326
Total minimum lease payments	8,835

(b) The Group leases its corporate offices in Hong Kong through a support service agreement with an indirect subsidiary of CK Hutchison Holdings Limited (“CK Hutchison”), which is the Company’s indirect major shareholder. The support service agreement may be terminated by giving 3-month advance notice; therefore, there was no lease commitment beyond the 3-month advance notice period as at December 31, 2018. This termination option is not considered probable of exercise for the purposes of applying ASC 842.

The Group recognized right-of-use assets as at January 1, 2019 measured at their carrying amounts as if ASC 842 had been applied since their commencement dates, but discounted using the lessees’ incremental borrowing rate as at January 1, 2019.

Recognized right-of-use assets upon adoption were as follows:

	(in US$’000)
Offices	4,877
Factories	383
Others	487
	5,747

There were no adjustments to net cash generated from/(used in) operating activities, investing activities or financing activities in the consolidated statement of cash flows.

In applying ASC 842 for the first time, the Group has used the following practical expedients permitted by the standard: (i) no reassessment of whether any expired or existing contracts are or contain leases; (ii) no reassessment of the lease classification for any expired or existing leases; (iii) the exclusion of initial direct costs for the measurement of the right-of-use assets at the date of initial application; and (iv) the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

Updated accounting policy—ASC 842

In an operating lease, a lessee obtains control of only the use of the underlying asset, but not the underlying asset itself. An operating lease is recognized as a right-of-use asset with a corresponding liability at the date which the leased asset is available for use by the Group. The Group recognizes an obligation to make lease payments equal to the present value of the lease payments over the lease term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.

F-22

Lease liabilities include the net present value of the following lease payments: (i) fixed payments; (ii) variable lease payments; and (iii) payments of penalties for terminating the lease if the lease term reflects the lessee exercising that option, if any. Lease liabilities exclude the following payments that are generally accounted for separately: (i) non-lease components, such as maintenance and security service fees and value added tax, and (ii) any payments that a lessee makes before the lease commencement date. The lease payments are discounted using the interest rate implicit in the lease or if that rate cannot be determined, the lessee’s incremental borrowing rate being the rate that the lessee would have to pay to borrow the funds in its currency and jurisdiction necessary to obtain an asset of similar value, economic environment and terms and conditions.

An asset representing the right to use the underlying asset during the lease term is recognized that consists of the initial measurement of the operating lease liability, any lease payments made to the lessor at or before the commencement date less any lease incentives received, any initial direct cost incurred by the Group and any restoration costs.

After commencement of the operating lease, the Group recognizes lease expenses on a straight-line basis over the lease term. The right-of-use asset is subsequently measured at cost less accumulated amortization and any impairment provision. The amortization of the right-of-use asset represents the difference between the straight-line lease expense and the accretion of interest on the lease liability each period. The interest amount is used to accrete the lease liability and to amortize the right-of-use asset. There is no amount recorded as interest expense.

Payments associated with short-term leases are recognized as lease expenses on a straight-line basis over the period of the leases.

Subleases of right-of-use assets are accounted for similar to other leases. As an intermediate lessor, the Group separately accounts for the head-lease and sublease unless it is relieved of its primary obligation under the head-lease. Sublease income is recorded on a gross basis separate from the head-lease expenses. If the total remaining lease cost on the head-lease is more than the anticipated sublease income for the lease term, this is an indicator that the carrying amount of the right-of-use asset associated with the head-lease may not be recoverable, and the right-of-use asset will be assessed for impairment.

Prior accounting policy - ASC 840

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the period of the leases.

Total operating lease rentals for factories and offices for the years ended December 31, 2018 and  2017 amounted to US$3,759,000 and US$2,285,000 respectively. Sublease rentals for the years ended December 31, 2018 and 2017 amounted to US$254,000 and US$274,000 respectively.

Interest Income

Interest generated from cash and cash equivalents and short-term investments is recorded over the period earned. It is measured based on the actual amount of interest the Group earns.

Income Taxes

The Group accounts for income taxes under the liability method. Under the liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the income tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of the net deferred income tax asset will not be realized.

The Group accounts for an uncertain tax position in the consolidated financial statements only if it is more likely than not that the position is sustainable based on its technical merits and consideration of the relevant tax authority’s widely understood administrative practices and precedents. If the recognition threshold is met, the Group records the largest amount of  tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement.

The Group recognizes interest and penalties for income taxes, if any, under income tax payable on its consolidated balance sheets and under other expenses in its consolidated statements of operations.

F-23

Comprehensive Loss

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions, and other events and circumstances from non-owner sources, and currently consists of net loss and foreign currency translation (loss)/gain related to the Company’s subsidiaries.

Losses per Share

Basic losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Weighted average number of outstanding ordinary shares in issue excludes treasury shares.

Diluted losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include ordinary shares and treasury shares issuable upon the exercise or settlement of share-based awards issued by the Company using the treasury stock method. The computation of diluted losses per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect.

Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief executive officer who is the Group’s chief operating decision maker. The chief operating decision maker reviews the Group’s internal reporting in order to assess performance and allocate resources and determined that the Group’s reportable segments are as disclosed in Note 25.

Profit Appropriation and Statutory Reserves

The Group’s subsidiaries and equity investees established in the PRC are required to make appropriations to certain non-distributable reserve funds.

In accordance with the relevant laws and regulations established in the PRC, the Company’s subsidiaries registered as wholly-owned foreign enterprise have to make appropriations from their after-tax profits (as determined under generally accepted accounting principles in the PRC (“PRC GAAP”)) to reserve funds including general reserve fund, enterprise expansion fund and staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the company. Appropriations to the enterprise expansion fund and staff bonus and welfare fund are made at the respective company’s discretion. For the Group’s equity investees, the amount of appropriations to these funds are made at the discretion of their respective boards.

In addition, Chinese domestic companies must make appropriations from their after-tax profits as determined under PRC GAAP to non-distributable reserve funds including statutory surplus fund and discretionary surplus fund. The appropriation to the statutory surplus fund must be 10% of the after-tax profits as determined under PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the company. Appropriation to the discretionary surplus fund is made at the respective company’s discretion.

The use of the general reserve fund, enterprise expansion fund, statutory surplus fund and discretionary surplus fund is restricted to the offsetting of losses or increases to the registered capital of the respective company. The staff bonus and welfare fund is a liability in nature and is restricted to fund payments of special bonus to employees and for the collective welfare of employees. All these reserves are not permitted to be transferred to the company as cash dividends, loans or advances, nor can they be distributed except under liquidation.

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including accounts receivable and other receivables. The Group currently does not expect ASU 2016-13 to have a material impact to the Group’s consolidated financial statements.

Amendments that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Group’s consolidated financial statements upon adoption.

4. Fair Value Disclosures

The following table presents the Group’s financial instruments by level within the fair value hierarchy:

	Fair Value Measurement Using
	Level 1	Level 2	Level 3	Total

Notes:

(a) The summarized statement of operations for NSPL for the year ended December 31, 2019 is presented up to December 9, 2019  when NSPL became a subsidiary of the Group. NSPL did not have any operating activities for the year ended December 31, 2019 and primarily incurred research and development expenses and an impairment provision during the years ended December 31, 2018 and 2017.

(b) On November 19, 2018, NSPL’s Board reviewed the progress of its drug candidates. After due consideration of the timeline and further investments required to complete NSPL’s clinical trials and reach the commercialization stage, it decided to explore alternative strategic options to maximize the economic returns from the drug candidates. NSPL performed an annual impairment assessment of the recoverability of the related US$30 million intangible asset by comparing its carrying amount to the higher of the asset’s value-in-use or its fair value less costs to sell. There was no certainty of an available market or that a suitable buyer or partner can be readily identified and accordingly, NSPL recorded a full impairment provision for the year ended December 31, 2018. The Company’s attributable portion was US$15 million.

(c) The main entities within the HBYS and SHPL  groups have been granted the High and New Technology Enterprise (“HNTE”) status. Accordingly, the entities were eligible to use a preferential income tax rate of 15% for the years ended December 31, 2019, 2018 and 2017.

In estimating the fair value of share options granted, the following assumptions were used in the Polynomial model for awards granted in the periods indicated:

	Year Ended December 31,
	2011		2013		2017		2018		2019
Weighted average grant date fair value of share options (in £ per share)		0.18		0.32		1.27		1.67		1.07
Significant inputs into the valuation model (weighted average):
Exercise price (in £ per share)		0.44		0.61		3.11		4.69		3.18
Share price at effective date of grant (in £ per share)		0.43		0.61		3.11		4.66		3.07
Expected volatility (note (a))		46.6%		36.0%		36.3%		37.6%		38.4%
Risk-free interest rate (note (b))		3.13%		3.16%		1.17%		1.46%		0.56%
Contractual life of share options (in years)		10		10		10		10		10
Expected dividend yield (note (c))		0%		0%		0%		0%		0%

Notes:

(a) The Company calculated its expected volatility with reference to the historical volatility prior to the issuances of share options.

(b) The risk-free interest rates used in the Polynomial model are with reference to the sovereign yield of the United Kingdom because the Company’s ordinary shares are currently listed on AIM and denominated in £.

(c) The Company has not declared or paid any dividends and does not currently expect to do so in the foreseeable future, and therefore uses an expected dividend yield of zero in the Polynomial model.

F-35

The Company will issue new shares to satisfy share option exercises. The following table summarizes the Company’s share option exercises:

	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Cash received from share options exercised	251	3,868	380
Total intrinsic value of share options exercised	1,189	9,394	2,290

The Group recognizes compensation expense on a graded vesting approach over the requisite service period. The following table presents share-based compensation expense included in the Group’s consolidated statements of operations:

	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Research and development expenses	6,634	7,280	1,284
Administrative expenses	539	623	—
	7,173	7,903	1,284

As at December 31, 2019, the total unrecognized compensation cost was US$9,229,000, and will be recognized on a graded vesting approach over the weighted average remaining service period of 2.74 years.

(ii)    LTIP

The Company grants awards under the LTIP to participating directors and employees, giving them a conditional right to receive ordinary shares of the Company or the equivalent ADS (collectively the “Awarded Shares”) to be purchased by the Trustee up to a cash amount. Vesting will depend upon continued employment of the award holder with the Group and will otherwise be at the discretion of the Board of Directors of the Company. Additionally, some awards are subject to change based on annual performance targets prior to their determination date.

LTIP awards prior to the determination date

Performance targets vary by award, and may include targets for shareholder returns, free cash flows, revenues, net profit after taxes and the achievement of clinical and regulatory milestones. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management’s assessment on the achievement of the performance target has been assigned to calculate the amount to be recognized as an expense over the requisite period with a corresponding entry to liability.

LTIP awards after the determination date

Upon the determination date, the Company will pay a determined monetary amount, up to the maximum cash amount based on the actual achievement of the performance target specified in the award, to the Trustee to purchase the Awarded Shares. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no Awarded Shares of the Company will be purchased and the amount previously recorded in the liability will be reversed through share-based compensation expense.

F-36

Granted awards under the LTIP are as follows:

	Maximum cash  amount per annum	Covered	Performance target
Grant date	(in US$ millions)	financial years	determination date

October 10, 2019	0.1	note (b)	note (b)

Notes:

(a) The annual performance target determination date is the date of the announcement of the Group’s annual results for the covered financial year and vesting occurs one business day after the publication date of the annual report of the Company for the financial year falling two years after the covered financial year to which the LTIP award relates.

(b) This award does not stipulate performance targets and is subject to a vesting schedule of 25% on each of the first, second, third and fourth anniversaries of the date of grant.

(c) This award did not stipulate performance targets and vested one business day after the publication date of the annual report for the 2017 financial year.

(d) The annual performance target determination date is the date of the announcement of the Group’s annual results for the covered financial year and vesting occurs two business days after the announcement of the Group’s annual results for the financial year falling two years after the covered financial year to which the LTIP award relates.

The Trustee has been set up solely for the purpose of purchasing and holding the Awarded Shares during the vesting period on behalf of the Group using funds provided by the Group. On the determination date, if any, the Company will determine the cash amount, based on the actual achievement of each annual performance target, for the Trustee to purchase the Awarded Shares. The Awarded Shares will then be held by the Trustee until they are vested.

The Trustee’s assets include treasury shares and funds for additional treasury shares, trustee fees and expenses. The number of treasury shares (in the form of ordinary shares or ADS of the Company) held by the Trustee were as follows:

	Number of	Cost
	treasury shares	(in US$’000)
As at January 1, 2017	629,215	2,390
Additions	350,940	1,367

Additions	60,430	346
Vested	(240,150)	(944)
As at December 31, 2019	941,310	6,079

Based on the actual achievement of performance targets for the 2019 financial year, the Group expects to purchase up to US$6,766,000 of treasury shares in 2020.

F-37

For the years ended December 31, 2019, 2018 and 2017, US$262,000, US$692,000 and US$79,000 of the LTIP awards were forfeited respectively.

The following table presents the share-based compensation expenses recognized under the LTIP awards:

	Year Ended December 31,
	2019	2018	2017

Notes:

(a) Sales of goods are recognized at a point-in-time and sales of services are recognized over time. The implementation of the two-invoice system in China over the periods presented resulted in a shift from a gross sales of goods revenue model to a net fee-for-service revenue model in the Group’s Commercial Platform, as the Group does not obtain control of the goods for distribution for relevant transactions and is thus considered an agent under ASC 606. Refer to Note 3.

(b) Goods— Innovative Medicines and royalties relate to revenue from a prescription drug developed by the Innovation Platform and launched into the market. It was represented under the Commercial Platform due to its transition to the commercial stage for segment reporting. Refer to Note 25.

(c) Under ASC 606, relates to the proportionate amount of milestone payment allocated to the license to the commercialization rights of a drug compound transferred at the inception date of the relevant license and collaboration contract. During the year ended December 31, 2018, the Group received a milestone of US$13.5 million, of which US$12.1 million was allocated to licenses and US$1.4 million was allocated to services.

(d) Under ASC 605, relates to milestone payments recognized under the milestone method.

(d) As at January 1, 2019, deferred revenue was US$2.9 million, of which US$2.2 million was recognized during the year ended December 31, 2019.

Innovation Platform

Innovation Platform revenue is mainly from license and collaboration agreements as follows:

License and collaboration agreement with Eli Lilly

On October 8, 2013, the Group entered into a licensing, co-development and commercialization agreement in China with Eli Lilly and Company (“Lilly”) relating to fruquintinib (“Lilly Agreement”), a targeted oncology therapy for the treatment of various types of solid tumors. Under the terms of the Lilly Agreement, the Group is entitled to receive a series of payments up to US$86.5 million, including upfront payments and development and regulatory approval milestones. Fruquintinib was successfully commercialized in China in November 2018, and the Group receives tiered royalties in the range of 15% to 20% on all sales in China. Development costs after the first development milestone are shared between the Group and Lilly.

In December 2018, the Group entered into various amendments to the Lilly Agreement (the “2018 Amendment”). Under the terms of the 2018 Amendment, the Group is entitled to determine and conduct future life cycle indications (“LCI”) development of fruquintinib in China beyond the three initial indications specified in the Lilly Agreement and will be responsible for all associated development costs. In return, the Group will receive additional regulatory approval milestones of US$20 million for each LCI approved, for up to three LCI or US$60 million in aggregate, and will increase tiered royalties to a range of 15% to 29% on all fruquintinib sales in China upon the commercial launch of the first LCI.

F-40

The 2018 Amendment provides the Group rights to promote fruquintinib in provinces that represent 30% of the sales of fruquintinib in China upon the occurrence of certain commercial milestones by Lilly. Such provinces will expand to 40% of the sales of fruquintinib in China subject to additional criteria being met. In return, Lilly will pay the Group service fees for such promotion and marketing services performed. Additionally, Lilly has provided consent, and freedom to operate, for the Group to enter into joint development collaborations with certain third-party pharmaceutical companies to explore combination treatments of fruquintinib and various immunotherapy agents.

Upfront and cumulative milestone payments according to the Lilly Agreement received up to December 31, 2019 are summarized as follows:

	(in US$’000)
Upfront payment	6,500
Development milestone payments achieved	40,000

In addition, the Group signed an option agreement which grants Lilly an exclusive option to expand the fruquintinib rights beyond Hong Kong and China. The option agreement further sets out certain milestone payments and royalty rates that apply in the event the option is exercised on a global basis. The option was determined at the inception of the contract to have minimal value, and in January 2019, Lilly elected not to exercise the option.

The Group adopted ASC 606 on January 1, 2018 and reassessed the Lilly Agreement under the new standard, which resulted in US$0.1 million recognition of previously deferred revenue as a cumulative adjustment to opening accumulated losses as at January 1, 2018, summarized as follows (in US$ millions).

	ASC 605		ASC 606
	December 31,	Opening	January 1,
	2017	Adjustments	2018
Cumulative amounts recognized to accumulated losses from:
Upfront payment (note (a))	5.7	0.5	6.2
Milestone payments (note (b))	23.7	(0.4)	23.3
	29.4	0.1	29.5

Notes:

(a) Upfront payment amounts deferred under ASC 605, but was allocated to the license to fruquintinib transferred at inception under ASC 606, resulting in additional revenue recognition on adoption.

(b) Milestone payments had been fully recognized under ASC 605’s milestone method, but was allocated to the portion of research and development services that had not been performed under ASC 606, resulting in deferral of revenue on adoption.

Under ASC 606, the Group identified the following performance obligations under the Lilly Agreement: (1) the license for the commercialization rights to fruquintinib and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to fruquintinib and the research and development services were 90% and 10% respectively. Control of the license to fruquintinib transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using the prior and estimated future development costs for fruquintinib as a measure of progress. Royalties are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

The Group identified the following performance obligations under the 2018 Amendment: (1) the research and development services for the LCI and (2) the promotion and marketing services. As at December 31, 2019, no regulatory approval milestones were achieved and no promotion and marketing services had commenced.

F-41

Revenue recognized under the Lilly Agreement by transaction price type is as follows:

	ASC 606		ASC 605
	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Research and development cost reimbursements	3,910	9,309	12,145

Note: During the years ended December 31, 2017 and 2018, the Group achieved milestones in relation to the acceptance and approval respectively, of a new drug application by the National Medical Products Administration of China for fruquintinib as a treatment of patients with advanced colorectal cancer.  During the year ended December 31, 2019, no milestones were achieved.

License and collaboration agreement with AstraZeneca

On December 21, 2011 (as amended on August 1, 2016), the Group and AstraZeneca AB (publ) (“AZ”) entered into a global licensing, co-development, and commercialization agreement for savolitinib (“AZ Agreement”), a novel targeted therapy and a highly selective inhibitor of the c-Met receptor tyrosine kinase for the treatment of cancer. Under the terms of the AZ Agreement, the Group is entitled to receive a series of payments up to US$140 million, including upfront payments and development and first-sale milestones. Additionally, the AZ Agreement contains possible significant future commercial sale milestones. Should savolitinib be successfully commercialized outside China, the Group would receive tiered royalties from 9% to 13% on all sales outside of China. Subject to approval of savolitinib in papillary renal cell carcinoma, the Group would receive increased tiered royalties from 14% to 18% on all sales outside of China, and after total aggregate sales of savolitinib have reached US$5 billion, this royalty will step down over a two-year period to an ongoing tiered royalty rate from 10.5% to 14.5%. Should savolitinib be successfully commercialized in China, the Group would receive fixed royalties of 30% based on all sales in China. Development costs for savolitinib in China will be shared between the Group and AZ, with the Group continuing to lead the development in China. AZ will lead and pay for the development of savolitinib for the rest of the world.

Upfront and cumulative milestone payments according to the AZ Agreement received up to December 31, 2019 are summarized as follows:

	(in US$’000)
Upfront payment	20,000
Development milestone payments achieved	25,000

The Group adopted ASC 606 on January 1, 2018 and reassessed the AZ Agreement under the new standard, which resulted in US$1.2 million deferral of previously recognized revenue as a cumulative adjustment to opening accumulated losses as at January 1, 2018, summarized as follows (in US$ millions).

	ASC 605		ASC 606
	December 31,	Opening	January 1,
	2017	Adjustments	2018
Cumulative amounts recognized to accumulated losses from:
Upfront payment (note (a))	19.6	(0.3)	19.3
Milestone payments (note (b))	24.9	(0.9)	24.0
	44.5	(1.2)	43.3

Notes:

(a) Upfront payment amounts allocated to research and development services recognized under ASC 606 differed from ASC 605 due to a different basis in measuring progress on adoption, resulting in deferral of revenue.

(b) Milestone payments had been fully recognized under ASC 605’s milestone method, but was allocated to the portion of research and development services that had not been performed under ASC 606, resulting in deferral of revenue on adoption.

F-42

Under ASC 606, the Group identified the following performance obligations under the AZ Agreement: (1) the license for the commercialization rights to savolitinib and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to savolitinib and the research and development services were 95% and 5% respectively. Control of the license to savolitinib transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using the prior and estimated future development costs for savolitinib as a measure of progress.

Revenue recognized under the AZ Agreement by transaction price type is as follows:

	ASC 606		ASC 605
	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Research and development cost reimbursements	10,883	5,876	3,058

Recognition and amortization of the milestone payments (note)	342	387	4,963
	11,527	6,536	8,087

Note: During the year ended December 31, 2017, the Group achieved a milestone in relation to the Phase III initiation for the secondary indication papillary renal cell carcinoma. During the years ended December 31, 2018 and 2019, no milestones were achieved.

21. Government Incentives

The Group receives government grants from the PRC Government (including the National level and Shanghai Municipal City). Government grants in the Innovation Platform are primarily given in support of Drug R&D activities and are conditional upon i) the Group spending a predetermined amount, regardless of success or failure of the research and development projects and ii) the achievement of certain stages of research and development projects being approved by the relevant PRC government authority. They are refundable to the PRC Government if the conditions, if any, are not met. Government grants in the Commercial Platform are primarily given to promote local initiatives. These government grants may be subject to ongoing reporting and monitoring by the PRC Government over the period of the grant.

Government incentives, which are deferred and recognized in the consolidated statements of operations over the period necessary to match them with the costs that they are intended to compensate, are recognized in other payable, accruals and advance receipts (Note 14) and other non-current liabilities. For the years ended December 31, 2019, 2018 and 2017, the Group received government grants of US$8,742,000, US$1,798,000 and US$1,323,000 respectively.

Deferred income tax	1,609	2,000	1,726
Income tax expense	3,274	3,964	3,080

Notes:

(a) The Company, two subsidiaries incorporated in the British Virgin Islands and its Hong Kong subsidiaries are subject to Hong Kong profits tax. In March 2018, the Hong Kong two-tiered profits tax rates regime was signed into law under which the first HK$2.0 million (US$0.3 million) of assessable profits of qualifying corporations will be taxed at 8.25%, with the remaining assessable profits taxed at 16.5%. Hong Kong profits tax has been provided for at the relevant rates on the estimated assessable profits less estimated available tax losses, if any, of these entities as applicable.

(b) Taxation in the PRC has been provided for at the applicable rate on the estimated assessable profits less estimated available tax losses, if any, in each entity. Under the PRC Enterprise Income Tax Law (the “EIT Law”), the standard enterprise income tax (“EIT”) rate is 25%. In addition, the EIT Law provides for, among others, a preferential tax rate of 15% for companies which qualify as HNTE. HMPL and its wholly-owned subsidiary Hutchison MediPharma (Suzhou) Limited qualify as a HNTE up to December 31, 2019 and 2020 respectively.

Pursuant to the EIT law, a 10% withholding tax is levied on dividends paid by PRC companies to their foreign investors. A lower withholding tax rate of 5% is applicable under the China-HK Tax Arrangement if direct foreign investors with at least 25% equity interest in the PRC companies are Hong Kong tax residents, and meet the conditions or requirements pursuant to the relevant PRC tax regulations regarding beneficial ownership. Since the equity holders of the major subsidiaries and equity investees of the Company are Hong Kong incorporated companies and Hong Kong tax residents, and meet the aforesaid conditions or requirements, the Company has used 5% to provide for deferred tax liabilities on retained earnings which are anticipated to be distributed. As at December 31, 2019 and 2018, the amounts accrued in deferred tax liabilities relating to withholding tax on dividends were determined on the basis that 100% of the distributable reserves of the major subsidiaries and equity investees operating in the PRC will be distributed as dividends.

F-46

(c) The Company’s subsidiary in the U.S. with operations in New Jersey and New York States is subject to U.S. taxes, primarily federal and state taxes, which have been provided for at approximately 21% (federal) and 9% and 16.55% (New Jersey and New York State respectively) on the estimated assessable profit respectively. Certain income receivable by the Company is subject to U.S. withholding tax of 30%. One of the Group’s subsidiaries is subject to Finland corporate tax at 20% on the estimated assessable profits in relation to its permanent establishment in Finland.

The reconciliation of the Group’s reported income tax expense to the theoretical tax amount that would arise using the tax rates of the Company against the Group’s loss before income taxes and equity in earnings of equity investees is as follows:

	Year Ended December 31,
	2019	2018	2017

(ii)    Deferred tax assets and liabilities

The significant components of deferred tax assets and liabilities are as follows:

	December 31,
	2019	2018
	(in US$’000)
Deferred tax assets
Tax losses	68,481	48,046
Others	1,733	1,555
Total deferred tax assets	70,214	49,601
Less: Valuation allowance	(69,399)	(49,021)

The movements in deferred tax assets and liabilities are as follows:

	2019	2018	2017
	(in US’000)
As at January 1	(4,256)	(3,819)	(4,989)

Exchange differences	132	190	(283)
As at December 31	(2,343)	(4,256)	(3,819)

F-47

The deferred tax assets and liabilities are offset when there is a legally enforceable right to set off and when the deferred income taxes relate to the same fiscal authority.

The tax losses can be carried forward against future taxable income and will expire in the following years:

	December 31,
	2019	2018
	(in US$’000)
No expiry date	40,897	52,866
2021	—	9
2022	182	182
2023	—	—
2024	3,716	4,081
2025	35,648	34,319
2026	47,661	48,328
2027	62,794	63,303
2028	106,793	111,753
2029	154,454	—
	452,145	314,841

The Company believes that it is more likely than not that future operations will not generate sufficient taxable income to realize the benefit of the deferred tax assets. The Company’s subsidiaries have had sustained tax losses, which will expire within five years if not utilized in the case of PRC subsidiaries (ten years for HNTEs), and which will not be utilized in the case of Hong Kong subsidiaries as they do not generate taxable profits. Accordingly, a valuation allowance has been recorded against the relevant deferred tax assets arising from the tax losses.

The table below summarizes changes in the deferred tax valuation allowance:

	2019	2018	2017
	(in US$’000)
As at January 1	49,021	31,662	20,145
Charged to consolidated statements of operations	25,498	19,414	11,410
Utilization of previously unrecognized tax losses	(285)	(329)	(387)
Write-off of tax losses	(3,142)	—	(558)
Others	—	(105)	(89)
Exchange differences	(1,693)	(1,621)	1,141
As at December 31	69,399	49,021	31,662

As at December 31, 2019 and 2018, the Group did not have any material unrecognized uncertain tax positions.

(iii)     Income tax payable

	2019	2018	2017
	(in US$’000)
As at January 1	555	979	274
Current tax	1,665	1,964	1,354

Exchange difference	(3)	(9)	8
As at December 31	1,828	555	979

Notes:

(a) The amount for 2019 excludes a non-current withholding tax of US$0.8 million which is included under other non-current liabilities.

(b) The amount for 2019 excludes the PRC EIT of US$0.3 million prepaid by HSPL which is included under other receivables, prepayments and deposits.

F-48

24. Losses per Share

(i)    Basic losses per share

Basic losses per share is calculated by dividing the net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Treasury shares held by the Trustee are excluded from the weighted average number of outstanding ordinary shares in issue for purposes of calculating basic losses per share.

	Year Ended December 31,
	2019	2018	2017
Weighted average number of outstanding ordinary shares in issue	665,683,145	664,263,820	617,171,710
Net loss attributable to the Company (US$’000)	(106,024)	(74,805)	(26,737)
Losses per share attributable to the Company (US$ per share)	(0.16)	(0.11)	(0.04)

(ii)    Diluted losses per share

Diluted losses per share is calculated by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include shares issuable upon the exercise or settlement of share option and LTIP awards issued by the Company using the treasury stock method.

For the years ended December 31, 2019, 2018 and 2017, the share options and LTIP awards issued by the Company were not included in the calculation of diluted losses per share because of their anti-dilutive effect. Therefore, diluted losses per share were equal to basic losses per share for the years ended December 31, 2019, 2018 and 2017.

25. Segment Reporting

The Group determines its operating segments from both business and geographic perspectives as follows:

(i) Innovation Platform (Drug R&D): focuses on discovering and developing for commercialization targeted therapies and immunotherapies for the treatment of cancer and immunological diseases; and

(ii) Commercial Platform: comprises of the manufacture, marketing and distribution of prescription drugs and over-the-counter pharmaceuticals in the PRC as well as consumer health products through Hong Kong. The Commercial Platform is further segregated into two core business areas:

(a) Prescription Drugs: comprises the development, manufacture, distribution, marketing and sale of prescription drugs; and

(b) Consumer Health: comprises the development, manufacture, distribution, marketing and sale of over-the-counter pharmaceuticals and consumer health products.

Innovation Platform and Prescription Drugs businesses under the Commercial Platform are primarily located in the PRC. The locations for Consumer Health business under the Commercial Platform are further segregated into the PRC and Hong Kong.

The performance of the reportable segments is assessed based on segment operating (loss)/profit.

F-49

In the second half of 2019, the Group began including the results from manufacturing and commercializing a prescription drug developed by the Innovation Platform and launched into the market under Prescription Drugs in the Commercial Platform. It has been included in the Commercial Platform due to its transition to the commercial stage and because commercial resources for innovative medicines are built under the Commercial Platform. The segment information below as at and for the year ended December 31, 2018 has been revised so that all segment disclosures are comparable. There was no revision necessary as at and for the year ended December 31, 2017.

27. Litigation

From time to time, the Group may become involved in litigation relating to claims arising from the ordinary course of business. The Group believes that there are currently no claims or actions pending against the Group, the ultimate disposition of which could have a material adverse effect on the Group’s results of operations, financial position or cash flows. However, litigation is subject to inherent uncertainties and the Group’s view of these matters may change in the future. When an unfavorable outcome occurs, there exists the possibility of a material adverse impact on the Group’s financial position and results of operations for the periods in which the unfavorable outcome occurs, and potentially in future periods.

On May 17, 2019, Luye Pharma Hong Kong Ltd. (“Luye”) issued a notice to the Group purporting to terminate a distribution agreement that granted the Group exclusive commercial rights to Seroquel in the PRC for failure to meet a pre-specified target. The Group disagrees with this assertion and believes that Luye have no basis for termination. As a result, the Group commenced legal proceedings in 2019 in order to compel Luye to comply with its obligations under the distribution agreement, or alternatively compensate the Group’s damages. The legal proceedings are still in progress. Accordingly, no adjustment has been made to Seroquel-related balances as at December 31, 2019, including accounts receivable, long-term prepayment, accounts payable and other payables of US$1.1 million, US$1.1 million, US$0.9 million and US$1.1 million respectively.

F-52

28. Restricted Net Assets

Relevant PRC laws and regulations permit payments of dividends by the Company’s subsidiaries in the PRC only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company’s subsidiaries in the PRC are required to make certain appropriations of net after-tax profits or increases in net assets to the statutory surplus fund prior to payment of any dividends. In addition, registered share capital and capital reserve accounts are restricted from withdrawal in the PRC, up to the amount of net assets held in each subsidiary. As a result of these and other restrictions under PRC laws and regulations, the Company’s subsidiaries in the PRC are restricted in their ability to transfer their net assets to the Group in terms of cash dividends, loans or advances, with restricted portions amounting to US$0.3 million and US$7.4 million as at December 31, 2019 and 2018 respectively, which excludes the Company’s subsidiaries with a shareholders’ deficit. Even though the Group currently does not require any such dividends, loans or advances from the PRC subsidiaries, for working capital and other funding purposes, the Group may in the future require additional cash resources from the Company’s subsidiaries in the PRC due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends to make distributions to shareholders.

In addition, the Group has certain investments in equity investees in the PRC, where the Group’s equity in undistributed earnings amounted to US$61.6 million and US$92.2 million as at December 31, 2019 and 2018 respectively.

29. Subsequent Events

The Group evaluated subsequent events through March 3, 2020, which is the date when the consolidated financial statements were issued.

In January 2020, the Company issued 22,000,000 ordinary shares in the form of 4,400,000 ADS for gross proceeds of US$110 million. In February 2020, the Company issued an additional 1,668,315 ordinary shares in the form of 333,663 ADS for gross proceeds of US$8.3 million.

Report of Independent Auditors

To the Board of Directors and Shareholders of Shanghai Hutchison Pharmaceuticals Limited

We have audited the accompanying consolidated financial statements of Shanghai Hutchison Pharmaceuticals Limited and its subsidiaries (the “Company”), which comprise the consolidated statements of financial position as of December 31, 2019 and 2018, and the related consolidated income statements, consolidated statements of comprehensive income, of changes in equity and of cash flows for each of the three years in the period ended December 31, 2019.

Management’s Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on the consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Shanghai Hutchison Pharmaceuticals Limited and its subsidiaries as of December 31, 2019 and 2018, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2019 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Notes to the Consolidated Financial Statements

1. General Information

Shanghai Hutchison Pharmaceuticals Limited (the “Company”) and its subsidiaries (together the “Group”) are principally engaged in manufacturing, selling and distribution of prescription drug products. The Group has manufacturing plants in the People’s Republic of China (the “PRC”) and sells mainly in the PRC.

The Company was incorporated in the PRC on April 30, 2001 as a Chinese-Foreign Equity joint venture. The Company is jointly controlled by Shanghai Hutchison Chinese Medicine (HK) Investment Limited (“SHCM(HK)IL”) and Shanghai Traditional Chinese Medicine Co., Ltd (“SHTCML”).

These consolidated financial statements are presented in United States dollars (“US$”), unless otherwise stated and have been approved for issue by the Company’s Board of Directors on March 3, 2020.

2. Summary of Significant Accounting Policies

The consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) and interpretations issued by the IFRS Interpretations Committee applicable to companies reporting under IFRS. The consolidated financial statements comply with IFRS as issued by the International Accounting Standards Board (“IASB”). These consolidated financial statements have been prepared under the historical cost convention.

During the year, the Group has adopted all of the new and revised standards, amendments and interpretations issued by the IASB that are relevant to the Group’s operations and mandatory for annual periods beginning January 1, 2019, including IFRS 16 Leases as described in Note 2(q) below. The adoption of these new and revised standards, amendments and interpretations did not have any material effects on the Group’s results of operations or financial position, except for the adoption of IFRS 16.

The following standards, amendments and interpretations were in issue but not yet effective for the financial year ended December 31, 2019 and have not been early adopted by the Group:

IAS 1 and IAS 8 (Amendments)(1)	Definition of Material
IFRS 3 (Amendments)(1)	Definition of a Business
IFRS 7, IFRS 9 and IAS 39 (Amendments)(1)	Interest rate benchmark reform
IFRS 17(2)	Insurance Contracts
IFRS 10 and IAS 28 (Amendments)(3)	Sale or Contribution of Assets between an Investor and its Associate or Joint Venture
Conceptual Framework for Financial Reporting(1)	Revised Conceptual Framework for Financial Reporting

(1) Effective for the Group for annual periods beginning on or after January 1, 2020.

(2) Effective for the Group for annual periods beginning on or after January 1, 2021.

(3) Effective date to be determined by the IASB.

The adoption of standards, amendments and interpretations listed above in future periods is not expected to have any material effects on the Group’s results of operations or financial position.

(a)    Basis of Consolidation

The consolidated financial statements of the Group include the financial statements of the Company and its subsidiaries.

The accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

F-61

Intercompany transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset.

(b)    Subsidiaries

Subsidiaries are all entities over which the Group has control. The Group controls an entity when the Group is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. In the consolidated financial statements, subsidiaries are accounted for as described in Note 2(a) above.

Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are de-consolidated from the date that control ceases.

(c)    Foreign Currency Translation

Items included in the financial statements of each of the Group’s companies are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The functional currency of the Company and its subsidiaries is Renminbi (“RMB”) whereas the consolidated financial statements are presented in US$, which is the Company’s presentation currency.

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign currency gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year end exchange rates are generally recognized in the consolidated income statements.

The financial statements of the Company and its subsidiaries are translated into the Company’s presentation currency using the year end rates of exchange for the statements of financial position items and the average rates of exchange for the year for the income statement items. Exchange translation differences are recognized directly in other comprehensive income.

(d)    Property, Plant and Equipment

Property, plant and equipment other than construction in progress are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes the purchase price of the asset and any directly attributable costs of bringing the asset to its working condition and location for its intended use.

Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. All other repairs and maintenance are charged to the consolidated income statements during the financial period in which they are incurred.

Depreciation is calculated using the straight-line method to allocate asset costs less accumulated impairment losses over their estimated useful lives. The principal estimated useful lives are as follows:

Buildings	20 years
Leasehold improvements	Over the unexpired period of the lease or 5 years, whichever is shorter
Plant and equipment	10 years
Furniture and fixtures, other equipment and motor vehicles	5 years

The assets’ useful lives are reviewed and adjusted, if appropriate, at the end of each reporting period. An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount.

Gains and losses on disposals are determined by comparing net sales proceeds with the carrying amount of the relevant assets and are recognized in the consolidated income statements.

F-62

(e)    Construction in Progress

Construction in progress represents buildings, plant and machinery under construction and pending installation and is stated at cost less accumulated impairment losses, if any. Cost includes the costs of construction of buildings and the costs of plant and machinery. No provision for depreciation is made on construction-in-progress until such time as the relevant assets are completed and ready for its intended use. When the assets concerned are brought into use, the costs are transferred to property, plant and equipment and depreciated in accordance with the policy as stated in Note 2(d).

(f)    Other Intangible Asset

The Group’s other intangible asset represents promotion and marketing rights. Other intangible asset has a definite useful life and is carried at historical cost less accumulated amortization and accumulated impairment losses, if any. Amortization is calculated using the straight-line method to allocate its cost over its estimated useful life of ten years.

(g)    Research and Development

Research expenditure is recognized as an expense as incurred. Costs incurred on development projects (relating to the design and testing of new or improved products) are recognized as intangible assets when it is probable that the project will generate future economic benefits by considering its commercial and technological feasibility, and costs can be measured reliably. Other development expenditures are recognized as an expense as incurred. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period. Development costs with a finite useful life that have been capitalized, if any, are amortized on a straight-line basis over the period of expected benefit not exceeding five years. The capitalized development costs are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset exceeds its recoverable amount.

Where the research phase and the development phase of an internal project cannot be clearly distinguished, all expenditure incurred on the project is charged to the consolidated income statements.

(h)    Impairment of Non-Financial Assets

Assets that have an indefinite useful life such as goodwill or intangible assets not ready to use are not subject to amortization and are tested for impairment annually. Assets are reviewed for impairment to determine whether there is any indication that the carrying value of these assets may not be recoverable and have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss, if any. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. Such impairment loss is recognized in the consolidated income statements.

(i)    Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

(j)    Trade and Other Receivables

Trade and other receivables are recognized initially at fair value, which is the amount of consideration that is unconditional. Trade and other receivables solely represent payments of principal and interest, if any, and the Group holds such financial assets with the objective to collect its contractual cash flows. Therefore, the Group measures them subsequently at amortized cost using the effective interest method, less any provision for impairment after the adoption of IFRS 9. The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables have been grouped based on shared credit risk characteristics and the days past due. All other receivables at amortized cost are considered to have low credit risk, and the loss allowance recognized during the period was therefore limited to 12 months expected losses. The amount of the provision is recognized in the consolidated income statements.

F-63

(k)    Cash and Cash Equivalents

In the consolidated statements of cash flows, cash and cash equivalents include cash on hand, bank deposits and other short-term highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, if any.

(l)    Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the consolidated income statements over the period of the borrowings using the effective interest method.

(m)    Financial Liabilities and Equity Instruments

Financial liabilities and equity instruments issued by the Group are classified according to the substance of the contractual arrangements entered into and the definitions of a financial liability and an equity instrument. Financial liabilities (including trade and other payables) are initially measured at fair value, and are subsequently measured at amortized cost, using the effective interest method. An equity instrument is any contract that does not meet the definition of a financial liability and evidences a residual interest in the assets of the Group after deducting all of its liabilities.

Ordinary shares are classified as equity. Incremental costs, net of tax, directly attributable to the issue of new shares are shown in equity as a deduction from the proceeds.

(n)    Current and Deferred Income Tax

(i)    Current income tax

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the country where the Group operates and generates taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

(ii)    Deferred income tax

Inside basis differences

Deferred income tax is recognized, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill and deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. Deferred income tax assets and deferred income tax liabilities are offset when there is a legally enforceable right to set off and when the deferred income taxes related to the same fiscal authority.

Outside basis differences

Deferred income tax liabilities are provided on taxable temporary differences arising from investments in subsidiaries, except for deferred income tax liabilities where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future.

F-64

Deferred income tax assets are recognized on deductible temporary differences arising from investments in subsidiaries, only to the extent that it is probable the temporary difference will reverse in the future and there is sufficient taxable profit available against which the temporary difference can be utilized.

(o)    Employee Benefits

The employees of the Group participate in defined contribution retirement benefit plans managed by the relevant municipal and provincial governments in the PRC. The assets of these plans are held separately from those of the Group. The Group is required to make monthly contributions to the plans calculated as a percentage of the employees’ salaries. The municipal and provincial governments undertake to assume the retirement benefit obligations to all existing and future retired employees under the plans described above. Other than the monthly contributions, the Group has no further obligations for the payment of the retirement and other post-retirement benefits of its employees.

(p)    Provisions

Provisions are recognized when the Group has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount has been reliably estimated. Provisions are not recognized for future operating losses.

(q)    Leases

The IASB has issued IFRS 16, a new standard for leases which replaced IAS 17. The core principle of IFRS 16 is that a lessee should recognize the assets and liabilities that arise from leases. A lessee should recognize on the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term.

The Group has adopted IFRS 16 retrospectively from January 1, 2019, but has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are therefore recognized in the opening balance sheet on January 1, 2019.

Right-of-use assets was measured on transition as if the new rules had always been applied. As a result, the Group has recognized a gross up to the consolidated statement of financial position on the date of adoption of US$1.0 million and US$0.9 million in right-of-use assets and lease liabilities respectively, primarily related to the Group’s various offices under non-cancellable lease agreements that were accounted as operating leases under IAS 17 as at December 31, 2018.

Under IFRS 16

A lease is recognized as a right-of-use asset with a corresponding liability at the date which the leased asset is available for use by the Group. The Group recognizes an obligation to make lease payments equal to the present value of the lease payments over the lease term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.

Lease liabilities include the net present value of the following lease payments: (i) fixed payments; (ii) variable lease payments that depend on an index or a rate; and (iii) payments of penalties for terminating the lease if the lease term reflects the lessee exercising that option, if any. Lease liabilities exclude the following payments that are generally accounted for separately: (i) non-lease components, such as maintenance and security service fees and value added tax, and (ii) any payments that a lessee makes before the lease commencement date. The lease payments are discounted using the interest rate implicit in the lease or if that rate cannot be determined, the lessee’s incremental borrowing rate being the rate that the lessee would have to pay to borrow the funds in its currency and jurisdiction necessary to obtain an asset of similar value, economic environment and terms and conditions.

An asset representing the right to use the underlying asset during the lease term is recognized that consists of the initial measurement of the lease liability, any lease payments made to the lessor at or before the commencement date less any lease incentives received, any initial direct cost incurred by the Group and any restoration costs.

F-65

After commencement of the lease, each lease payment is allocated between lease liability and finance costs. The finance costs are recognized over the lease term so as to produce a constant periodic rate of interest on the remaining balance of the lease liability for each period. The right-of-use asset is depreciated on a straight-line basis over the period of the lease.

Payments associated with short-term leases are recognized as lease expenses on a straight-line basis over the period of the leases.

Leasehold land is accounted under IFRS 16.

The lease liabilities were measured at the present value of the remaining lease payments, discounted using the lessees’ incremental borrowing rate as at January 1, 2019. The Group’s weighted average incremental borrowing rate applied on January 1, 2019 was 4.75% per annum.

A reconciliation of the Group’s reported operating lease commitments as at December 31, 2018 and the Group’s lease liabilities recognized upon adoption of IFRS 16 as at January 1, 2019 is as follows:

	(in US$’000)
Operating lease commitments as at December 31, 2018 (note)	1,241
Less: Leases not commenced as at January 1, 2019	(187)
Less: Short-term leases	(36)
Less: Discount under the lessees’ incremental borrowing rate as at January 1, 2019	(87)
Lease liabilities recognized as at January 1, 2019	931

Note: Future aggregate minimum payments under non-cancellable operating leases under IAS 17 were as follows:

	December 31, 2018
	(in US$’000)
Not later than 1 year	610
Between 1 to 2 years	521
Between 2 to 3 years	98
Between 3 to 4 years	7
Between 4 to 5 years	5
	1,241

The Group recognized right-of-use assets as at January 1, 2019 measured at their carrying amounts as if IFRS 16 had been applied since their commencement dates, but discounted using the lessees’ incremental borrowing rate as at January 1, 2019.

Recognized right-of-use assets upon adoption, excluding leasehold land, were offices of US$1.0 million.

There were no adjustments to net cash generated from/(used in) operating activities, investing activities or financing activities in the consolidated statement of cash flows.

In applying IFRS 16 for the first time, the Group has used the following practical expedients permitted by the standard: (i) no reassessment of whether any expired or existing contracts are or contain leases; (ii) no reassessment of the lease classification for any expired or existing leases; (iii) the exclusion of initial direct costs for the measurement of the right-of-use assets at the date of initial application; and (iv) the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

Under IAS 17

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the consolidated income statements on a straight-line basis over the period of the leases.

Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale. All other borrowing costs are recognized in the consolidated income statements in the period in which they are incurred.

(s)    Government Incentives

Incentives from government are recognized at their fair values where there is a reasonable assurance that the incentives will be received and all attached conditions will be complied with.

Government incentives relating to costs are deferred and recognized in the consolidated income statements over the period necessary to match them with the costs that they are intended to compensate.

Government grants relating to property, plant and equipment are included in other payables, accruals and advance receipts and non-current liabilities as deferred income and credited to the consolidated income statements on a straight-line basis over the expected lives of the related assets.

(t)    Revenue and Income Recognition

Under IFRS 15

The Group applied IFRS 15 to all contracts at the date of initial application of January 1, 2018 using the modified retrospective method. For sales of goods, the Group applied a portfolio approach to aggregate contracts into portfolios whose performance obligations do not differ materially from each other. In its assessment of each portfolio, the Group assessed the contracts under the new five-step model under IFRS 15 and determined there was no significant impact to the timing or amount of revenue recognition under the new guidance. The Group’s accounting policy for revenue recognition subsequent to January 1, 2018 is detailed below.

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Group from a customer, are also excluded from revenue. The Group recognizes revenue when it satisfies a performance obligation by transferring control over a good to a customer.

The Group principally generates revenue from sales of goods. Revenue from sales of goods is recognized when the customer takes possession of the goods. This usually occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, the Group recognizes revenue from provision of services based on amounts that can be invoiced to the customer.

Payments in advance from customers are deferred if consideration is received in advance of transferring control of the goods or rendering of services. Accounts receivable is recognized if the Group has an unconditional right to bill the customer, which is generally when the customer takes possession of the goods or services are rendered. Payment terms differ by subsidiary and customer, but generally range from 45 to 180 days from the invoice date.

Under IAS 18

The Group’s accounting policy for revenue recognition before January 1, 2018 is detailed below.

F-67

Revenue comprises the fair value of the consideration received and receivable for the sales of goods in the ordinary course of the Group’s activities. The Group recognizes revenue when the amount of revenue can be reliably measured; when it is probable that future economic benefits will flow to the entity; and when specific criteria have been met for each of the Group’s activities, as described below.

Revenue is shown net of value-added tax, returns, volume rebates and discounts after eliminating sales within the Group. Revenue and income are recognized as follows:

(i)    Sales of goods

Sales of goods are recognized when a group entity has delivered products to the customer, the customer has accepted the products and collectability of the related receivables is reasonably assured.

(ii)    Sales rebates

Certain sales rebates are provided to customers when their business performance for an agreed period within the year and the whole year meets certain criteria. Sales rebates are recognized in profit or loss based on management’s estimation at each year end.

(iii)    Other service income

Other service income is recognized when services are rendered.

(u)    Interest Income

Interest income is recognized on a time-proportion basis using the effective interest method.

(v)    Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision makers. The Company’s Board of Directors, which is responsible for allocating resources and assessing performance of the operating segments, has been identified as the steering committee that makes strategic decisions.

(w)    General Reserves

In accordance with the laws applicable to Foreign Investment Enterprises established in the PRC, the Company makes appropriations to certain non-distributable reserve funds including the general reserve fund, the enterprise expansion fund and the staff bonus and welfare fund. The amount of appropriations to these funds are made at the discretion of the Company’s Board of Directors.

3. Financial Risk Management

(a)    Financial risk factors

The Group’s activities expose it to a variety of financial risks, including credit risk, cash flow interest rate risk and liquidity risk. The Group does not use any derivative financial instruments for speculative purposes.

(i)    Credit risk

The carrying amounts of cash and cash equivalents, trade receivables (including bills receivables) and other receivables included in the consolidated statements of financial position represent the Group’s maximum exposure to credit risk of the counterparty in relation to its financial assets.

Substantially all of the Group’s cash and cash equivalents are deposited in major financial institutions, which management believes are of high credit quality. The Group has a practice to limit the amount of credit exposure to any financial institution.

Bills receivables are mostly settled by state-owned banks or other reputable banks and therefore the management considers that they will not expose the Group to any significant credit risk.

F-68

The Group has no significant concentrations of credit risk. The Group has policies in place to ensure that the sales of products are made to customers with appropriate credit history and the Group performs periodic credit evaluations of its customers.

Management periodically assesses the recoverability of trade receivables and other receivables. The Group’s historical loss rates are adjusted to reflect current and forward-looking information on specific factors affecting the ability of the customers to settle the receivables, and historical experience collecting receivables falls within the recorded allowances.

(ii)    Cash flow interest rate risk

As at December 31, 2019 and 2018, the Group has no significant interest-bearing assets except for cash and cash equivalents, details of which have been disclosed in Note 10, and no interest-bearing bank borrowings.

(iii)    Liquidity risk

Prudent liquidity management implies maintaining sufficient cash and cash equivalents and the availability of funding when necessary. The Group’s policy is to regularly monitor current and expected liquidity requirements to ensure that it maintains sufficient cash balances and adequate credit facilities to meet its liquidity requirements in the short and long term.

As at December 31, 2019 and 2018, the Group’s current financial liabilities were mainly due for settlement within twelve months and the Group expects to meet all liquidity requirements.

(b)    Capital risk management

The Group’s objectives when managing capital are to safeguard the Group’s ability to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

The Group regularly reviews and manages its capital structure to ensure an optimal balance between higher shareholders’ return that might be possible with higher levels of borrowings and the advantages and security afforded by a sound capital position, and makes adjustments to the capital structure in light of changes in economic conditions.

The Group monitors capital on the basis of the liabilities to assets ratio. This ratio is calculated as total liabilities divided by total assets as shown on the consolidated statements of financial position.

Currently, it is the Group’s strategy to maintain a reasonable liabilities to assets ratio. The liabilities to assets ratio as at December 31, 2019 and 2018 was as follows:

	December 31,
	2019		2018
	(in US$’000)
Total liabilities	85,607		91,266
Total assets	232,345		223,044
Liabilities to assets ratio	36.8	%	40.9	%

(c)    Fair value estimation

The Group does not have any financial assets or liabilities which are carried at fair value. The carrying amounts of the Group’s current financial assets, including cash and cash equivalents, trade and bills receivables and other receivables, and current financial liabilities, including trade payables, other payables and accruals and lease liabilities, approximate their fair values due to their short-term maturities. The carrying amounts of the Group’s financial instruments carried at cost or amortized cost are not materially different from their fair values.

The face values less any estimated credit adjustments for financial assets and liabilities with a maturity of less than one year are assumed to approximate their fair values. The fair value of financial liabilities for disclosure purposes is estimated by discounting the future contractual cash flows at the current market interest rate that is available to the Group for similar financial instruments.

F-69

4. Critical Accounting Estimates and Judgements

Note 2 includes a summary of the significant accounting policies used in the preparation of the consolidated financial statements. The preparation of consolidated financial statements often requires the use of judgements to select specific accounting methods and policies from several acceptable alternatives. Furthermore, significant estimates and assumptions concerning the future may be required in selecting and applying those methods and policies in the consolidated financial statements. The Group bases its estimates and judgements on historical experience and various other assumptions that it believes are reasonable under the circumstances. Actual results may differ from these estimates and judgements under different assumptions or conditions.

The following is a review of the more significant assumptions and estimates, as well as the accounting policies and methods used in the preparation of the consolidated financial statements.

(a)    Sales rebates

Certain sales rebates are provided to customers when their business performance for an agreed period within the year and the whole year meets certain criteria as stipulated in the contracts. Sales rebates are considered variable consideration and the estimate of sales rebates during the year is based on estimated sales transactions for the entire period stipulated and is subject to change based on actual performance and collection status.

(b)    Useful lives of property, plant and equipment

The Group has made substantial investments in property, plant and equipment. Changes in technology or changes in the intended use of these assets may cause the estimated period of use or value of these assets to change.

(c)    Deferred income tax

Deferred tax is recognized using the liability method on temporary differences arising between the tax bases of assets and liabilities against which the deductible temporary differences and the carry forward of unused tax losses and tax credits can be utilized. Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. Where the final outcomes are different from the estimations, such differences will impact the carrying amount of deferred tax in the period in which such determination is made.

5. Revenue and Segment Information

Management has reviewed the Group’s internal reporting in order to assess performance and allocate resources, and has determined that the Group has two reportable operating segments as follows:

—Manufacturing business—manufacture and distribution of drug products

—Distribution business—provision of sales, distribution and marketing services to pharmaceutical manufacturers

The operating segments are strategic business units that offer different products and services. They are managed separately because each business requires different technology and marketing approaches. The performance of each of the reportable segments is assessed based on a measure of operating profit/ (loss).

Management’s Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on the consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Hutchison Whampoa Guangzhou Baiyunshan Chinese Medicine Company Limited and its subsidiaries as of December 31, 2019 and 2018, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2019 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Hutchison Whampoa Guangzhou Baiyunshan Chinese Medicine Company Limited

Notes to the Consolidated Financial Statements

1. General Information

Hutchison Whampoa Guangzhou Baiyunshan Chinese Medicine Company Limited (the “Company”) and its subsidiaries (together the “Group”) are principally engaged in manufacturing, selling and distribution of over-the-counter drug products. The Group has manufacturing plants in the People’s Republic of China (the “PRC”) and sells mainly in the PRC.

The Company was incorporated in the PRC on April 12, 2005 as a Chinese-Foreign Equity joint venture. The Company is jointly controlled by Guangzhou Hutchison Chinese Medicine (HK) Investment Limited (“GZHCMHK”) and Guangzhou Baiyunshan Pharmaceutical Holdings Company Limited (“GBPHCL”).

These consolidated financial statements are presented in United States dollars (“US$”), unless otherwise stated and have been approved for issue by the Company’s Board of Directors on March 3, 2020.

2. Summary of Significant Accounting Policies

The consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) and interpretations issued by the IFRS Interpretations Committee applicable to companies reporting under IFRS. The consolidated financial statements comply with IFRS as issued by the International Accounting Standards Board (“IASB”). These consolidated financial statements have been prepared under the historical cost convention.

During the year, the Group has adopted all of the new and revised standards, amendments and interpretations issued by the IASB that are relevant to the Group’s operations and mandatory for annual periods beginning January 1, 2019, including IFRS 16 Leases as described in Note 2(v) below. The adoption of these new and revised standards, amendments and interpretations did not have any material effects on the Group’s results of operations or financial position, except for the adoption of IFRS 16.

The following standards, amendments and interpretations were in issue but not yet effective for the financial year ended December 31, 2019 and have not been early adopted by the Group:

IAS 1 and IAS 8 (Amendments)(1)	Definition of Material
IFRS 3 (Amendments)(1)	Definition of a Business
IFRS 7, IFRS 9 and IAS 39 (Amendments)(1)	Interest rate benchmark reform
IFRS 17(2)	Insurance Contracts
IFRS 10 and IAS 28 (Amendments)(3)	Sale or Contribution of Assets between an Investor and its Associate or Joint Venture
Conceptual Framework for Financial Reporting(1)	Revised Conceptual Framework for Financial Reporting

(1) Effective for the Group for annual periods beginning on or after January 1, 2020.

(2) Effective for the Group for annual periods beginning on or after January 1, 2021.

(3) Effective date to be determined by the IASB.

The adoption of standards, amendments and interpretations listed above in future periods is not expected to have any material effects on the Group’s results of operations or financial position.

(a)    Basis of Consolidation

The consolidated financial statements of the Group include the financial statements of the Company and its subsidiaries, and also include the Group’s interests in a joint venture and associated companies on the basis set out in Notes 2(d) and 2(e) below.

The accounting policies of subsidiaries, the joint venture and associated companies have been changed where necessary to ensure consistency with the policies adopted by the Group.

F-89

Intercompany transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset.

Non-controlling interests represent the interests of outside shareholders in the operating results and net assets of subsidiaries.

(b)    Subsidiaries

Subsidiaries are all entities over which the Group has control. The Group controls an entity when the Group is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. In the consolidated financial statements, subsidiaries are accounted for as described in Note 2(a) above.

Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are de-consolidated from the date that control ceases.

(c)    Transactions with Non-controlling Interests

Transactions with non-controlling interests that do not result in a loss of control are accounted for as transactions with equity owners of the Group. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

(d)    Joint Arrangements

Investments in joint arrangements are classified either as joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Group has assessed the nature of its joint arrangement and determined it to be a joint venture. The joint venture is accounted for using the equity method.

Under the equity method of accounting, the interest in joint venture is initially recognized at cost and adjusted thereafter to recognize the Group’s share of the post-acquisition profits or losses and movements in other comprehensive income. The Group determines at each reporting date whether there is any objective evidence that the investment in the joint venture is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the joint venture and its carrying value and recognizes the amount in the consolidated income statements.

(e)    Associated Companies

An associate is an entity, other than a subsidiary or a joint venture, in which the Group has a long-term equity interest and over which the Group is in position to exercise significant influence over its management, including participation in the financial and operating policy decisions.

The results and net assets of associates are incorporated in these financial statements using the equity method of accounting, except when the investment is classified as held for sale, in which case it is accounted for under IFRS 5, Non-current assets held for sale and discontinued operations. The total carrying amount of such investments is reduced to recognize any identified impairment loss in the value of individual investments.

(f)    Foreign Currency Translation

Items included in the financial statements of each of the Group’s companies are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The functional currency of the Company and its subsidiaries, joint venture and associated companies is Renminbi (“RMB”) whereas the consolidated financial statements are presented in US$, which is the Company’s presentation currency.

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign currency gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year end exchange rates are generally recognized in the consolidated income statements.

F-90

The financial statements of the Company, subsidiaries, joint venture and associated companies are translated into the Company’s presentation currency using the year end rates of exchange for the statements of financial position items and the average rates of exchange for the year for the income statement items. Exchange translation differences are recognized directly in other comprehensive (loss)/income.

(g)    Property, Plant and Equipment

Property, plant and equipment other than construction in progress are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes the purchase price of the asset and any directly attributable costs of bringing the asset to its working condition and location for its intended use.

Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. All other repairs and maintenance are charged to the consolidated income statements during the financial period in which they are incurred.

Depreciation is calculated using the straight-line method to allocate asset costs less accumulated impairment losses over their estimated useful lives. The principal estimated useful lives are as follows:

Buildings and facilities	10-30 years
Plant and equipment	10 years
Furniture and fixtures, other equipment and motor vehicles	5 years

The assets’ useful lives are reviewed and adjusted, if appropriate, at the end of each reporting period. An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount.

Gains and losses on disposals are determined by comparing net sales proceeds with the carrying amount of the relevant assets and are recognized in the consolidated income statements.

(h)    Construction in Progress

Construction in progress represents buildings, plant and machinery under construction and pending installation and is stated at cost less accumulated impairment losses, if any. Cost includes the costs of construction of buildings and the costs of plant and machinery. No provision for depreciation is made on construction in progress until such time as the relevant assets are completed and ready for its intended use. When the assets concerned are brought into use, the costs are transferred to property, plant and equipment and depreciated in accordance with the policy as stated in Note 2(g).

(i)    Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the Group’s share of the net identifiable assets of the acquired subsidiary/business at the date of acquisition, or the excess of fair value of business over its fair value of the net identifiable assets injected into the Company upon its formation. If the cost of acquisition is less than the fair value of the Group’s share of the net identifiable assets of the acquired subsidiary, the difference is recognized directly in the consolidated income statements.

Goodwill is retained at the carrying amount as a separate asset, and subject to impairment test annually when there are indications that the carrying value may not be recoverable.

The profit or loss on disposal of a subsidiary is calculated by reference to the net assets at the date of disposal including the attributable amount of goodwill.

F-91

(j)    Other Intangible Assets

The Group’s other intangible assets mainly include distribution network and drugs licenses contributed from non-controlling shareholders. Other intangible assets have a definite useful life and are carried at historical cost less accumulated amortization and accumulated impairment losses, if any. Amortization is calculated using the straight-line method to allocate costs over the estimated useful lives of ten years.

(k)    Research and Development

Research expenditure is recognized as an expense as incurred. Costs incurred on development projects (relating to the design and testing of new or improved products) are recognized as intangible assets when it is probable that the project will generate future economic benefits by considering its commercial and technological feasibility, and costs can be measured reliably. Other development expenditures are recognized as an expense as incurred. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period. Development costs with a finite useful life that have been capitalized, if any, are amortized on a straight-line basis over the period of expected benefit not exceeding five years. The capitalized development costs are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset exceeds its recoverable amount.

Where the research phase and the development phase of an internal project cannot be clearly distinguished, all expenditure incurred on the project is charged to the consolidated income statements.

(l)    Impairment of Non-Financial Assets

Assets that have an indefinite useful life such as goodwill or intangible assets not ready to use are not subject to amortization and are tested for impairment annually. Assets are reviewed for impairment to determine whether there is any indication that the carrying value of these assets may not be recoverable and have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss, if any. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. Such impairment loss is recognized in the consolidated income statements.

(m)    Non-current Assets (or Disposal Groups) Classified As Held For Sale

Non-current assets (or disposal groups) are classified as held for sale when their carrying amount is to be recovered principally through a sale transaction and a sale is considered highly probable. The non-current assets (or disposal groups) except for certain assets as explained below, are stated at the lower of carrying amount and fair value less costs to sell. Deferred tax assets, and financial assets (other than investments in subsidiaries and associates), which are classified as held for sale, would continue to be measured in accordance with the policies set out elsewhere in Note 2.

(n)    Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

(o)    Trade and Other Receivables

Trade and other receivables are recognized initially at fair value, which is the amount of consideration that is unconditional. Trade and other receivables solely represent payments of principal and interest, if any, and the Group holds such financial assets with the objective to collect its contractual cash flows. Therefore, the Group measures them subsequently at amortized cost using the effective interest method, less any provision for impairment after the adoption of IFRS 9. The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables have been grouped based on shared credit risk characteristics and the days past due. All other receivables at amortized cost are considered to have low credit risk, and the loss allowance recognized during the period was therefore limited to 12 months expected losses. The amount of the provision is recognized in the consolidated income statements.

F-92

(p)    Cash and Cash Equivalents

In the consolidated statements of cash flows, cash and cash equivalents include cash on hand, bank deposits and other short-term highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value, if any.

(q)    Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the consolidated income statements over the period of the borrowings using the effective interest method.

(r)    Financial Liabilities and Equity Instruments

Financial liabilities and equity instruments issued by the Group are classified according to the substance of the contractual arrangements entered into and the definitions of a financial liability and an equity instrument. Financial liabilities (including trade and other payables) are initially measured at fair value, and are subsequently measured at amortized cost, using the effective interest method. An equity instrument is any contract that does not meet the definition of financial liability and evidences a residual interest in the assets of the Group after deducting all of its liabilities.

Ordinary shares are classified as equity. Incremental costs, net of tax, directly attributable to the issue of new shares are shown in equity as a deduction from the proceeds.

(s)    Current and Deferred Income Tax

(i)    Current income tax

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the country where the Group operates and generates taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

(ii)    Deferred income tax

Inside basis differences

Deferred income tax is recognized, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill and deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. Deferred income tax assets and deferred income tax liabilities are offset when there is a legally enforceable right to set off and when the deferred income taxes related to the same fiscal authority.

F-93

Outside basis differences

Deferred income tax liabilities are provided on taxable temporary differences arising from investments in subsidiaries, associates and joint arrangements, except for deferred income tax liabilities where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future. Generally the Group is unable to control the reversal of the temporary difference for associates. Only when there is an agreement in place that gives the Group the ability to control the reversal of the temporary difference in the foreseeable future, deferred tax liability in relation to taxable temporary differences arising from the associate’s undistributed profits is not recognized.

Deferred income tax assets are recognized on deductible temporary differences arising from investments in subsidiaries, associates and joint arrangements only to the extent that it is probable the temporary difference will reverse in the future and there is sufficient taxable profit available against which the temporary difference can be utilized.

(t)    Employee Benefits

The employees of the Group participate in defined contribution retirement benefit plans managed by the relevant municipal and provincial governments in the PRC. The assets of these plans are held separately from those of the Group. The Group is required to make monthly contributions to the plans, calculated as a percentage of the employees’ salaries. The municipal and provincial governments undertake to assume the retirement benefit obligations to all existing and future retired employees under the plans described above. Other than the monthly contributions, the Group has no further obligations for the payment of the retirement and other post-retirement benefits of its employees.

(u)    Provisions

Provisions are recognized when the Group has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount has been reliably estimated. Provisions are not recognized for future operating losses.

(v)    Leases

The IASB has issued IFRS 16, a new standard for leases which replaced IAS 17. The core principle of IFRS 16 is that a lessee should recognize the assets and liabilities that arise from leases. A lessee should recognize on the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term.

The Group has adopted IFRS 16 retrospectively from January 1, 2019, but has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are therefore recognized in the opening balance sheet on January 1, 2019.

Right-of-use assets was measured on transition as if the new rules had always been applied. As a result, the Group has recognized a gross up to the consolidated statement of financial position on the date of adoption of US$0.6 million and US$0.6 million in right-of-use assets and lease liabilities respectively, primarily related to the Group’s various warehouses under non-cancellable lease agreements that were accounted as operating leases under IAS 17 as at December 31, 2018.

Under IFRS 16

A lease is recognized as a right-of-use asset with a corresponding liability at the date which the leased asset is available for use by the Group. The Group recognizes an obligation to make lease payments equal to the present value of the lease payments over the lease term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.

F-94

Lease liabilities include the net present value of the following lease payments: (i) fixed payments; (ii) variable lease payments that depend on an index or a rate; and (iii) payments of penalties for terminating the lease if the lease term reflects the lessee exercising that option, if any. Lease liabilities exclude the following payments that are generally accounted for separately: (i) non-lease components, such as maintenance and security service fees and value added tax, and (ii) any payments that a lessee makes before the lease commencement date. The lease payments are discounted using the interest rate implicit in the lease or if that rate cannot be determined, the lessee’s incremental borrowing rate being the rate that the lessee would have to pay to borrow the funds in its currency and jurisdiction necessary to obtain an asset of similar value, economic environment and terms and conditions.

An asset representing the right to use the underlying asset during the lease term is recognized that consists of the initial measurement of the lease liability, any lease payments made to the lessor at or before the commencement date less any lease incentives received, any initial direct cost incurred by the Group and any restoration costs.

After commencement of the lease, each lease payment is allocated between lease liability and finance costs. The finance costs are recognized over the lease term so as to produce a constant periodic rate of interest on the remaining balance of the lease liability for each period. The right-of-use asset is depreciated on a straight-line basis over the period of the lease.

Payments associated with short-term leases are recognized as lease expenses on a straight-line basis over the period of the leases.

Leasehold land is accounted under IFRS 16.

The lease liabilities were measured at the present value of the remaining lease payments, discounted using the lessees’ incremental borrowing rate as at January 1, 2019. The Group’s weighted average incremental borrowing rate applied on January 1, 2019 was 4.75% per annum.

A reconciliation of the Group’s reported operating lease commitments as at December 31, 2018 and the Group’s lease liabilities recognized upon adoption of IFRS 16 as at January 1, 2019 is as follows:

	(in US$’000)
Operating lease commitments as at December 31, 2018 (note)	1,232
Less: Short-term leases	(535)
Less: Discount under the lessees’ incremental borrowing rate as at January 1, 2019	(60)
Lease liabilities recognized as at January 1, 2019	637

Note: Future aggregate minimum payments under non-cancellable operating leases under IAS 17 were as follows:

	December 31, 2018
	(in US$’000)
Not later than 1 year	885
Between 1 to 2 years	144
Between 2 to 3 years	151
Between 3 to 4 years	52
	1,232

The Group recognized right-of-use assets as at January 1, 2019 measured at their carrying amounts as if IFRS 16 had been applied since their commencement dates, but discounted using the lessees’ incremental borrowing rate as at January 1, 2019.

Recognized right-of-use assets upon adoption, excluding leasehold land, were warehouses of US$0.6 million.

There were no adjustments to net cash generated from/(used in) operating activities, investing activities or financing activities in the consolidated statement of cash flows.

F-95

In applying IFRS 16 for the first time, the Group has used the following practical expedients permitted by the standard: (i) no reassessment of whether any expired or existing contracts are or contain leases; (ii) no reassessment of the lease classification for any expired or existing leases; (iii) the exclusion of initial direct costs for the measurement of the right-of-use assets at the date of initial application; and (iv) the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

Under IAS 17

Leases that transfer substantially all the rewards and risks of ownership of the assets to the Group, other than legal title, are accounted for as finance leases. At the inception of a finance lease, the cost of the leased asset is capitalized at the present value of the minimum lease payments and recorded together with the obligation, excluding the interest element, to reflect the purchase and financing. Assets held under capitalized finance leases, including prepaid land lease payments under finance leases, are included in property, plant and equipment, and depreciated over the shorter of the lease terms and the estimated useful lives of the assets. The finance costs of such leases are charged to the consolidated income statements so as to provide a constant periodic rate of charge over the lease terms.

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the consolidated income statements on a straight-line basis over the period of the leases.

(w)    Borrowing Costs

Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale. All other borrowing costs are recognized in the consolidated income statements in the period in which they are incurred.

(x)    Government Incentives

Incentives from government are recognized at their fair values where there is a reasonable assurance that the incentives will be received and all attached conditions will be complied with.

Government incentives relating to costs are deferred and recognized in the consolidated income statements over the period necessary to match them with the costs that they are intended to compensate.

Government grants relating to property, plant and equipment are included in other payables, accruals and advance receipts and non-current liabilities as deferred income and credited to the consolidated income statements on a straight-line basis over the expected lives of the related assets.

(y)    Revenue and Income Recognition

Under IFRS 15

The Group applied IFRS 15 to all contracts at the date of initial application of January 1, 2018 using the modified retrospective method. For sales of goods, the Group applied a portfolio approach to aggregate contracts into portfolios whose performance obligations do not differ materially from each other. In its assessment of each portfolio, the Group assessed the contracts under the new five-step model under IFRS 15 and determined there was no significant impact to the timing or amount of revenue recognition under the new guidance. The Group’s accounting policy for revenue recognition subsequent to January 1, 2018 is detailed below.

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Group from a customer, are also excluded from revenue. The Group recognizes revenue when it satisfies a performance obligation by transferring control over a good to a customer.

F-96

The Group principally generates revenue from sales of goods. Revenue from sales of goods is recognized when the customer takes possession of the goods. This usually occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, the Group recognizes revenue from provision of services based on amounts that can be invoiced to the customer.

Payments in advance from customers are deferred if consideration is received in advance of transferring control of the goods or rendering of services. Accounts receivable is recognized if the Group has an unconditional right to bill the customer, which is generally when the customer takes possession of the goods or services are rendered. Payment terms differ by subsidiary and customer, but generally range from 45 to 180 days from the invoice date.

Under IAS 18

The Group’s accounting policy for revenue recognition before January 1, 2018 is detailed below.

Revenue comprises the fair value of the consideration received and receivable for the sales of goods in the ordinary course of the Group’s activities. The Group recognizes revenue when the amount of revenue can be reliably measured; when it is probable that future economic benefits will flow to the entity; and when specific criteria have been met for each of the Group’s activities, as described below.

Revenue is shown net of value-added tax, returns, volume rebates and discounts after eliminating sales within the Group. Revenue and income are recognized as follows:

(i)    Sales of goods

Sales of goods are recognized when a group entity has delivered products to the customer, the customer has accepted the products and collectability of the related receivables is reasonably assured.

(ii)    Sales rebates

Certain sales rebates are provided to customers when their business performance for an agreed period within the year and the whole year meets certain criteria. Sales rebates are recognized in profit or loss based on management’s estimation at each year end.

(iii)    Other service income

Other service income is recognized when services are rendered.

(z)    Interest income

Interest income is recognized on a time-proportion basis using the effective interest method.

(aa)    Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-makers. The Company’s Board of Directors, which is responsible for allocating resources and assessing performance of the operating segments, has been identified as the steering committee that makes strategic decisions.

F-97

(ab)    General Reserves

In accordance with the laws applicable to Foreign Investment Enterprises established in the PRC, the Company makes appropriations to certain non-distributable reserve funds including the general reserve fund, the enterprise expansion fund and the staff bonus and welfare fund. The amount of appropriations to these funds are made at the discretion of the Company’s Board of Directors.

3. Financial Risk Management

(a)    Financial risk factors

The Group’s activities expose it to a variety of financial risks, including credit risk, cash flow interest rate risk and liquidity risk. The Group does not use any derivative financial instruments for speculative purposes.

(i)    Credit risk

The carrying amounts of cash and cash equivalents, trade receivables (including bills receivables) and other receivables included in the consolidated statements of financial position represent the Group’s maximum exposure to credit risk of the counterparty in relation to its financial assets.

Substantially all of the Group’s cash and cash equivalents are deposited in major financial institutions, which management believes are of high credit quality.

Bills receivables are mostly settled by state-owned banks or other reputable banks and therefore the management considers that they will not expose the Group to any significant credit risk.

The Group has no significant concentrations of credit risk. The Group has policies in place to ensure that the sales of products are made to customers with appropriate credit history and the Group performs periodic credit evaluations of its customers.

Management periodically assesses the recoverability of trade receivables and other receivables. The Group’s historical loss rates are adjusted to reflect current and forward-looking information on specific factors affecting the ability of the customers to settle the receivables, and historical experience collecting receivables falls within the recorded allowances.

(ii)    Cash flow interest rate risk

As at December 31, 2019 and 2018, the Group has no significant interest-bearing assets except for cash and cash equivalents, details of which have been disclosed in Note 11, and no interest-bearing bank borrowings.

(iii)    Liquidity risk

Prudent liquidity management implies maintaining sufficient cash and cash equivalents and the availability of funding when necessary. The Group’s policy is to regularly monitor current and expected liquidity requirements to ensure that it maintains sufficient cash balances and adequate credit facilities to meet its liquidity requirements in the short and long term.

As at December 31, 2019 and 2018, the Group’s current financial liabilities were mainly due for settlement within twelve months and the Group expects to meet all liquidity requirements. Additionally, the Group’s financial liabilities include current and non-current dividends payable to shareholders (refer to Note 25(b)), for which shareholders will only require settlement when sufficient cash and cash equivalents are available.

(b)    Capital risk management

The Group’s objectives when managing capital are to safeguard the Group’s ability to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

F-98

The Group regularly reviews and manages its capital structure to ensure an optimal balance between higher shareholders’ return that might be possible with higher levels of borrowings and the advantages and security afforded by a sound capital position, and makes adjustments to the capital structure in light of changes in economic conditions.

The Group monitors capital on the basis of the liabilities to assets ratio. This ratio is calculated as total liabilities divided by total assets as shown on the consolidated statements of financial position.

Currently, it is the Group’s strategy to maintain a reasonable liabilities to assets ratio. The liabilities to assets ratio as at December 31, 2019 and 2018 was as follows:

	December 31,
	2019		2018
	(in US$’000)
Total liabilities (note)	172,741		91,276
Total assets	219,772		216,373
Liabilities to assets ratio	78.6	%	42.2	%

Note: On December 30, 2019, the Company declared dividends to shareholders of US$79.3 million which were not settled as at December 31, 2019.

(c)    Fair value estimation

The Group does not have any financial assets or liabilities which are carried at fair value. The carrying amounts of the Group’s current financial assets, including cash and cash equivalents, trade and bills receivables and other receivables, and current financial liabilities, including trade payables, other payables and accruals, lease liabilities and dividend payable, approximate their fair values due to their short-term maturities. The carrying amounts of the Group’s financial instruments carried at cost or amortized cost are not materially different from their fair values.

The face values less any estimated credit adjustments for financial assets and liabilities with a maturity of less than one year are assumed to approximate their fair values. The fair value of financial liabilities for disclosure purposes is estimated by discounting the future contractual cash flows at the current market interest rate that is available to the Group for similar financial instruments.

4. Critical Accounting Estimates and Judgements

Note 2 includes a summary of the significant accounting policies used in the preparation of the consolidated financial statements. The preparation of consolidated financial statements often requires the use of judgements to select specific accounting methods and policies from several acceptable alternatives. Furthermore, significant estimates and assumptions concerning the future may be required in selecting and applying those methods and policies in the consolidated financial statements. The Group bases its estimates and judgements on historical experience and various other assumptions that it believes are reasonable under the circumstances. Actual results may differ from these estimates and judgements under different assumptions or conditions.

The following is a review of the more significant assumptions and estimates, as well as the accounting policies and methods used in the preparation of the consolidated financial statements.

(a)    Sales rebates

Certain sales rebates are provided to customers when their business performance for the whole year meets certain criteria as stipulated in the contracts. Sales rebates are considered variable consideration and the estimate of sales rebates during the year is based on estimated sales transactions for the entire period stipulated and is subject to change based on actual performance and collection status.

(b)    Useful lives of property, plant and equipment

The Group has made substantial investments in property, plant and equipment. Changes in technology or changes in the intended use of these assets may cause the estimated period of use or value of these assets to change.

F-99

(c)    Impairment of non-financial assets

The Group tests annually whether goodwill has suffered any impairment. Other non-financial assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset exceeds its recoverable amount in accordance with the accounting policy stated in Note 2(l). The recoverable amount of an asset or a cash-generating unit is determined based on the higher of the asset’s or the cash-generating unit’s fair value less costs to disposal and value-in-use. The value-in-use calculation requires the entity to estimate the future cash flows expected to arise from the asset and a suitable discount rate in order to calculate present value, and the growth rate assumptions in the cash flow projections which has been prepared on the basis of management’s assumptions and estimates.

(d)    Deferred income tax

Deferred tax is recognized using the liability method on temporary differences arising between the tax bases of assets and liabilities against which the deductible temporary differences and the carry forward of unused tax losses and tax credits can be utilized. Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. Where the final outcomes are different from the estimations, such differences will impact the carrying amount of deferred tax in the period in which such determination is made.

5. Revenue and Segment Information

Management has reviewed the Group’s internal reporting in order to assess performance and allocate resources, and has determined that the Group has two reportable operating segments as follows:

—Manufacturing business—manufacture and distribution of drug products

—Distribution business—provision of sales, distribution and marketing services to pharmaceutical manufacturers

The operating segments are strategic business units that offer different products and services. They are managed separately because each business requires different technology and marketing approaches. The performance of each of the reportable segments is assessed based on operating profit.

The segment information is as follows:

Revenue from external customers is after elimination of inter-segment sales. The amount eliminated was US$0.7 million for 2019 (2018: US$1.9 million; 2017: US$3.0 million). Sales between segments are carried out at mutually agreed terms. Revenue from external customers is primarily for sales of goods which are recognized at a point in time, except for provision of services which are recognized over time of US$3.1 million in 2019 (2018: US$3.4 million; 2017: US$0.7 million) and included in the manufacturing business operating segment.

Report of Independent Auditors

To the Board of Directors and Shareholders of Nutrition Science Partners Limited

We have audited the accompanying consolidated financial statements of Nutrition Science Partners Limited and its subsidiary (the “Company”), which comprise the consolidated statements of financial position as of December 9, 2019 and December 31, 2018, and the related consolidated income statements, consolidated statements of comprehensive income/(loss), of changes in equity and of cash flows for the period ended December 9, 2019 and each of the two years in the period ended December 31, 2018.

Management’s Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on the consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Nutrition Science Partners Limited and its subsidiary as of December 9, 2019 and December 31, 2018, and the results of their operations and their cash flows for the period ended December 9, 2019 and each of the two years in the period ended December 31, 2018, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Nutrition Science Partners Limited

Notes to the Consolidated Financial Statements

1. General Information

Nutrition Science Partners Limited (the “Company”) and its subsidiary (together, the “Group”) are principally engaged in the research and development of pharmaceutical products. The Company was incorporated in Hong Kong on May 28, 2012 as a limited liability company. The registered office of the Company is located at 48th Floor, Cheung Kong Center, 2 Queen’s Road Central, Hong Kong.

On November 27, 2012, Hutchison MediPharma (Hong Kong) Limited (“HMPHK”), a subsidiary of Hutchison China MediTech Limited (“Chi-Med”, which together with its subsidiaries, hereinafter collectively referred to as the “Chi-Med Group”) and Nestlé Health Science S.A. (“NHS”), a subsidiary of Nestlé S.A. (“Nestlé”), entered into a joint venture agreement (“JV Agreement”). Pursuant to the JV Agreement, Nestlé agreed to contribute cash of US$30 million and the Chi-Med Group agreed to contribute assets and business processes including (i) the global development and commercial rights of a novel, oral therapy drug candidate for Inflammatory Bowel Disease and (ii) the exclusive rights to its extensive botanical library and well-established botanical research and development platform in the field of gastrointestinal disease into the Company. The Company was jointly owned by HMPHK and NHS with 50% equity interest each. On December 9, 2019, HMPHK acquired NHS’ 50% shareholding in the Company from NHS (the “Transaction”) and terminated the JV Agreement. After the Transaction, the Company became a wholly owned subsidiary of HMPHK.

These consolidated financial statements are presented up to the period ended December 9, 2019 when the Company was a non-consolidated affiliate of Chi-Med for their inclusion in Chi-Med’s annual report on Form 20-F for the fiscal year ended December 31, 2019. These consolidated financial statements are presented in United States dollars (“US$”), unless otherwise stated and have been approved for issue by the Company’s Board of Directors (the “Board”) on March 3, 2020.

2. Summary of Significant Accounting Policies

The consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) and interpretations issued by the IFRS Interpretations Committee applicable to companies reporting under IFRS. The consolidated financial statements comply with IFRS as issued by International Accounting Standards Board (“IASB”). These consolidated financial statements have been prepared under the historical cost convention.

During the period, the Group has adopted all of the new and revised standards, amendments and interpretations issued by the IASB that are relevant to the Group’s operations and mandatory for annual periods beginning January 1, 2019. The adoption of these new and revised standards, amendments and interpretations did not have any material effects on the Group’s results of operations or financial position.

The following standards, amendments and interpretations were in issue but not yet effective for the financial year ended December 31, 2019 and have not been early adopted by the Group:

IAS 1 and IAS 8 (Amendments)(1)	Definition of Material
IFRS 3 (Amendments)(1)	Definition of a Business
IFRS 7, IFRS 9 and IAS 39 (Amendments)(1)	Interest rate benchmark reform
IFRS 17(2)	Insurance Contracts
IFRS 10 and IAS 28 (Amendments)(3)	Sale or Contribution of Assets between an Investor and its Associate or Joint Venture
Conceptual Framework for Financial Reporting(1)	Revised Conceptual Framework for Financial Reporting

(1) Effective for the Group for annual periods beginning on or after January 1, 2020.

(2) Effective for the Group for annual periods beginning on or after January 1, 2021.

(3) Effective date to be determined by the IASB.

F-121

The adoption of standards, amendments and interpretations listed above in future periods is not expected to have any material effects on the Group’s results of operations or financial position.

(a)    Basis of Consolidation

The consolidated financial statements of the Group include the financial statements of the Company and its subsidiary. The financial statements of the subsidiary are prepared for the same reporting period as the Company, using consistent accounting policies. The results of the subsidiary are consolidated from the date on which the Group obtained control, and will continue to be consolidated until the date that such control ceases. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation.

(b)    Subsidiary

The subsidiary is an entity over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. In the consolidated financial statements, the subsidiary is accounted for as described in Note 2(a) above.

(c)    Foreign Currency Translation

Items included in the financial statements of each of the Group’s companies are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The functional currency of the Company and its subsidiary as well as the presentation currency of the Group is US$.

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign currency gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year end exchange rates are generally recognized in the income statement.

(d)    Segment Reporting

The Group has one operating segment which conducts research and development activities. All segment assets are located in Hong Kong. The Board has been identified as the Group’s chief operating decision-maker and reviews the consolidated results of the Group for the purposes of resource allocation and performance assessment. Therefore, no additional reportable segment and geographical information has been presented.

(e)    Intangible Assets

Intangible assets acquired separately are measured on initial recognition at cost. The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets with finite lives are subsequently amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least annually. The Group has no intangible assets with indefinite lives.

(f)    Research and Development Costs

All research costs are charged to the consolidated income statements as incurred.

Expenditures incurred on projects to develop new products are capitalized and deferred only when the Group can demonstrate the technical feasibility of completing the intangible asset so that it will be available for use or sale, its intention to complete and its ability to use or sell the asset, how the asset will generate future economic benefits, the availability of resources to complete the project and the ability to measure the expenditure reliably during the development. Product development expenditures which do not meet these criteria are expensed when incurred.

(g)    Cash and Cash Equivalents

In the consolidated statements of cash flows, cash and cash equivalents comprise cash at bank.

F-122

(h)    Provisions

Provisions are recognized when the Group has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated. Provisions are not recognized for future operating losses.

(i)    Income Tax

The current tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the countries where the Company and its subsidiary operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and establish provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

3. Financial Risk Management

(i)   Financial Risk Factors

The Group’s activities expose it to a variety of financial risks, including credit risk and liquidity risk. The Group does not use any derivative financial instruments for speculative purposes.

(a)   Credit Risk

The carrying amounts of cash and cash equivalents included in the consolidated statements of financial position represent the Group’s maximum exposure to credit risk of the counterparty in relation to its financial asset. The Group’s bank balance is maintained with a creditworthy bank with no recent history of default.

(b)    Liquidity Risk

The Group’s objective is to maintain a balance between continuity of funding and flexibility through balances with related parties and shareholders.

As at December 9, 2019 and December 31, 2018, the Group’s current financial liabilities were all contractually due for settlement within twelve months and the Group expects to meet all liquidity requirements.

(ii)    Capital Management

The primary objective of the Group’s capital management is to safeguard the Group’s ability to continue as a going concern.

The Group manages its capital structure and makes adjustments to it in light of changes in economic conditions and the risk characteristics of the underlying assets. To maintain or adjust the capital structure, the Group may issue new shares. The Group is not subject to any externally imposed capital requirements. No changes were made to these objectives, policies or processes for managing capital during the period ended December 9, 2019 and the years ended December 31, 2018 and 2017.

(iii)    Fair Value Estimation

The fair values of the financial asset and liabilities of the Group approximate their carrying amounts largely due to the short term maturities of these instruments.

F-123

4. Critical Accounting Estimates and Judgements

Note 2 includes a summary of the significant accounting policies used in the preparation of the consolidated financial statements. The preparation of the consolidated financial statements often requires the use of judgements to select specific accounting methods and policies from several acceptable alternatives. Furthermore, significant estimates and assumptions concerning the future may be required in selecting and applying those methods and policies in the consolidated financial statements. The Group bases its estimates and judgements on historical experience and various other assumptions that it believes are reasonable under the circumstances. Actual results may differ from these estimates and judgements under different assumptions or conditions.

The following is a review of the more significant assumptions and estimates, as well as the accounting policies and methods used in the preparation of the consolidated financial statements.

(i)    Impairment of intangible asset

The Group tests annually whether an intangible asset not ready for use has incurred any impairment. Assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets exceeds its recoverable amount in accordance with the accounting policy stated in Note 2(e). The recoverable amount of an asset or a cash-generating unit is determined based on the higher of the asset’s or the cash-generating unit’s fair value less costs to sell and value-in-use. The value-in-use calculation requires the entity to estimate the future cash flows expected to arise from the asset and a suitable discount rate in order to calculate present value, and the growth rate assumptions in the cash flow projections which have been prepared on the basis of management’s assumptions and estimates. The fair value less costs to sell for an asset not traded in an active market is determined using valuation techniques (level 3 in the fair value hierarchy).

During the year ended December 31, 2018, the Group recorded a full impairment provision of the intangible asset. Refer to Note 6.

5. Significant Related Party Transactions

(i)    The Group has the following significant transactions during the period/years with related parties which were carried out in the normal course of business at terms equivalent to those that prevail in arm’s length transactions and agreed by the relevant parties:

	Period Ended December 9,	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Service fees charged by a subsidiary of Chi-Med	—	6,973	8,893

On March 25, 2013, Hutchison MediPharma Limited (“HMP”), a subsidiary of Chi-Med, and NHS entered into a research and development collaboration agreement as contemplated by the JV Agreement for the exclusive rights to conduct research to evaluate and develop products from HMP’s extensive botanical library and well established botanical research and development platform in the field of gastrointestinal disease.

On November 19, 2018, the Board decided to put on hold the Company’s research activities pending a strategic review. Refer to Note 6. On December 9, 2019, the collaboration agreement was terminated along with the JV Agreement.

(ii)    Other transaction with related party:

On March 25, 2013, the Company and Nestec Ltd., an affiliate of NHS, entered into an option agreement for the exclusive option to obtain exclusive royalty-bearing licenses to commercialize certain products in certain territories. The exercise price of the option is either fixed or subject to negotiation upon the receipt of the exercise notice, depending on the territories.

The option was never exercised and on December 9, 2019, the option agreement was terminated along with the JV Agreement.

(iii)    Compensation of key management personnel of the Group:

No compensation was paid by the Group to the key management personnel of the Group in respect of their services rendered to the Group during the period ended December 9, 2019 and the years ended December 31, 2018 and 2017.

F-124

6. Impairment Provision

On November 19, 2018, the Board reviewed the progress of its drug candidates. After due consideration of the timeline and further investments required to complete the clinical trials and reach the commercialization stage, it decided to explore alternative strategic options to maximize the economic returns from the drug candidates. The Group has performed an annual impairment assessment of the recoverability of the US$30 million intangible asset by comparing its carrying amount to the higher of the asset’s value-in-use or its fair value less costs to sell. In preparing its assessment, although the Group was in the process of identifying potential buyers or collaboration partners to maximize its economics returns from the drug candidates, there was no certainty of an available market or that a suitable buyer or partner can be readily identified. Accordingly, the Group recorded a full impairment provision during the year ended December 31, 2018. During the period ended December 9, 2019, there were no further developments on the drug candidates that would indicate a reversal of impairment was appropriate.

7. Taxation Charge

No Hong Kong profits tax has been provided as the Group had no assessable profit for the period ended December 9, 2019 and the years ended December 31, 2018 and 2017.

The taxation on the Group’s profit/(loss) before taxation differs from the theoretical account that would arise using the applicable tax rate as follows:

	Period Ended
	December 9,	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Profit/(loss) before taxation	199	(38,198)	(9,210)
Calculated at a taxation rate of 16.5%	33	(6,303)	(1,520)
Net effect of (income not taxable)/expenses not tax deductible	(33)	6,303	1,520
Taxation charge	—	—	—

8. Cash and Cash Equivalents

	December 9,	December 31,
	2019	2018
	(in US$’000)
Cash at bank	16,769	17,320

The carrying amounts of the cash and cash equivalents are denominated in US$.

9. Amounts Due to Related Parties

	December 9,	December 31,
	2019	2018
	(in US$’000)
Subsidiaries of Chi-Med	30	73

The amounts due to related parties are unsecured, interest free and repayable on demand.

Notes:

(a) The summarized statement of operations for NSPL for the year ended December 31, 2019 is presented up to December 9, 2019  when NSPL became a subsidiary of the Group. NSPL did not have any operating activities for the year ended December 31, 2019 and primarily incurred research and development expenses and an impairment provision during the years ended December 31, 2018 and 2017.

(b) On November 19, 2018, NSPL’s Board reviewed the progress of its drug candidates. After due consideration of the timeline and further investments required to complete NSPL’s clinical trials and reach the commercialization stage, it decided to explore alternative strategic options to maximize the economic returns from the drug candidates. NSPL performed an annual impairment assessment of the recoverability of the related US$30 million intangible asset by comparing its carrying amount to the higher of the asset’s value-in-use or its fair value less costs to sell. There was no certainty of an available market or that a suitable buyer or partner can be readily identified and accordingly, NSPL recorded a full impairment provision for the year ended December 31, 2018. The Company’s attributable portion was US$15 million.

(c) The main entities within the HBYS and SHPL  groups have been granted the High and New Technology Enterprise (“HNTE”) status. Accordingly, the entities were eligible to use a preferential income tax rate of 15% for the years ended December 31, 2019, 2018 and 2017.

Based on the Group’s operating plan, the existing cash and cash equivalents, short-term investments and unutilized bank borrowing facilities are considered to be sufficient to meet the cash requirements to fund planned operations and other commitments for at least the next twelve months (the look-forward period used).

18. Share-based Compensation

(i)    Share-based Compensation of the Company

The Company conditionally adopted a share option scheme on June 4, 2005 (as amended on March 21, 2007) and such scheme has a term of 10 years. It expired in 2016 and no further share options can be granted. Another share option scheme was conditionally adopted on April 24, 2015 (the “HCML Share Option Scheme”). Pursuant to the HCML Share Option Scheme, the Board of Directors of the Company may, at its discretion, offer any employees and directors (including Executive and Non-executive Directors but excluding Independent Non-executive Directors) of the Company, holding companies of the Company and any of their subsidiaries or affiliates, and subsidiaries or affiliates of the Company share options to subscribe for shares of the Company.

As at December 31, 2019, the aggregate number of shares issuable under the HCML Share Option Scheme is 23,130,970 ordinary shares and the aggregate number of shares issuable under the prior share option scheme which expired in 2016 is 1,516,180 ordinary shares. Additionally, the number of shares authorized but unissued was 833,093,550 ordinary shares.

Share options granted are generally subject to a four-year vesting schedule, depending on the nature and the purpose of the grant. Share options subject to the four-year vesting schedule, in general, vest 25% upon the first anniversary of the vesting commencement date as defined in the grant letter, and 25% every subsequent year. However, certain share option grants may have a different vesting schedule as approved by the Board of Directors of the Company. No outstanding share options will be exercisable or subject to vesting after the expiry of a maximum of eight to ten years from the date of grant.

A summary of the Company’s share option activity and related information is as follows:

In estimating the fair value of share options granted, the following assumptions were used in the Polynomial model for awards granted in the periods indicated:

	Year Ended December 31,
	2011		2013		2017		2018		2019
Weighted average grant date fair value of share options (in £ per share)		0.18		0.32		1.27		1.67		1.07
Significant inputs into the valuation model (weighted average):
Exercise price (in £ per share)		0.44		0.61		3.11		4.69		3.18
Share price at effective date of grant (in £ per share)		0.43		0.61		3.11		4.66		3.07
Expected volatility (note (a))		46.6%		36.0%		36.3%		37.6%		38.4%
Risk-free interest rate (note (b))		3.13%		3.16%		1.17%		1.46%		0.56%
Contractual life of share options (in years)		10		10		10		10		10
Expected dividend yield (note (c))		0%		0%		0%		0%		0%

Notes:

(a) The Company calculated its expected volatility with reference to the historical volatility prior to the issuances of share options.

(b) The risk-free interest rates used in the Polynomial model are with reference to the sovereign yield of the United Kingdom because the Company’s ordinary shares are currently listed on AIM and denominated in £.

(c) The Company has not declared or paid any dividends and does not currently expect to do so in the foreseeable future, and therefore uses an expected dividend yield of zero in the Polynomial model.

The Company will issue new shares to satisfy share option exercises. The following table summarizes the Company’s share option exercises:

	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Cash received from share options exercised	251	3,868	380
Total intrinsic value of share options exercised	1,189	9,394	2,290

The Group recognizes compensation expense on a graded vesting approach over the requisite service period. The following table presents share-based compensation expense included in the Group’s consolidated statements of operations:

	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Research and development expenses	6,634	7,280	1,284
Administrative expenses	539	623	—
	7,173	7,903	1,284

As at December 31, 2019, the total unrecognized compensation cost was US$9,229,000, and will be recognized on a graded vesting approach over the weighted average remaining service period of 2.74 years.

(ii)    LTIP

The Company grants awards under the LTIP to participating directors and employees, giving them a conditional right to receive ordinary shares of the Company or the equivalent ADS (collectively the “Awarded Shares”) to be purchased by the Trustee up to a cash amount. Vesting will depend upon continued employment of the award holder with the Group and will otherwise be at the discretion of the Board of Directors of the Company. Additionally, some awards are subject to change based on annual performance targets prior to their determination date.

LTIP awards prior to the determination date

Performance targets vary by award, and may include targets for shareholder returns, free cash flows, revenues, net profit after taxes and the achievement of clinical and regulatory milestones. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management’s assessment on the achievement of the performance target has been assigned to calculate the amount to be recognized as an expense over the requisite period with a corresponding entry to liability.

LTIP awards after the determination date

Upon the determination date, the Company will pay a determined monetary amount, up to the maximum cash amount based on the actual achievement of the performance target specified in the award, to the Trustee to purchase the Awarded Shares. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no Awarded Shares of the Company will be purchased and the amount previously recorded in the liability will be reversed through share-based compensation expense.

Granted awards under the LTIP are as follows:

	Maximum cash  amount per annum	Covered	Performance target
Grant date	(in US$ millions)	financial years	determination date
October 19, 2015	1.8	2014 - 2016	note (a)
March 24, 2016	0.3	note (b)	note (b)
March 15, 2017	0.4	note (c)	note (c)
March 15, 2017 and August 2, 2017	6.0	2017 - 2019	note (d)
December 15, 2017	0.5	2018 - 2019	note (d)
August 6, 2018	0.1	2018 - 2019	note (d)
December 14, 2018	1.5	2019	note (d)
August 5, 2019	0.7	2019	note (d)
October 10, 2019	0.1	note (b)	note (b)

Notes:

(a) The annual performance target determination date is the date of the announcement of the Group’s annual results for the covered financial year and vesting occurs one business day after the publication date of the annual report of the Company for the financial year falling two years after the covered financial year to which the LTIP award relates.

(b) This award does not stipulate performance targets and is subject to a vesting schedule of 25% on each of the first, second, third and fourth anniversaries of the date of grant.

(c) This award did not stipulate performance targets and vested one business day after the publication date of the annual report for the 2017 financial year.

(d) The annual performance target determination date is the date of the announcement of the Group’s annual results for the covered financial year and vesting occurs two business days after the announcement of the Group’s annual results for the financial year falling two years after the covered financial year to which the LTIP award relates.

The Trustee has been set up solely for the purpose of purchasing and holding the Awarded Shares during the vesting period on behalf of the Group using funds provided by the Group. On the determination date, if any, the Company will determine the cash amount, based on the actual achievement of each annual performance target, for the Trustee to purchase the Awarded Shares. The Awarded Shares will then be held by the Trustee until they are vested.

The Trustee’s assets include treasury shares and funds for additional treasury shares, trustee fees and expenses. The number of treasury shares (in the form of ordinary shares or ADS of the Company) held by the Trustee were as follows:

	Number of	Cost
	treasury shares	(in US$’000)
As at January 1, 2017	629,215	2,390
Additions	350,940	1,367
Vested	(420,380)	(1,800)
As at December 31, 2017	559,775	1,957
Additions	795,005	5,451
Vested	(233,750)	(731)
As at December 31, 2018	1,121,030	6,677
Additions	60,430	346
Vested	(240,150)	(944)
As at December 31, 2019	941,310	6,079

Based on the actual achievement of performance targets for the 2019 financial year, the Group expects to purchase up to US$6,766,000 of treasury shares in 2020.

For the years ended December 31, 2019, 2018 and 2017, US$262,000, US$692,000 and US$79,000 of the LTIP awards were forfeited respectively.

The following table presents the share-based compensation expenses recognized under the LTIP awards:

	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Research and development expenses	2,640	1,000	1,894

Liability	2,694	764	2,336
Additional paid-in capital	1,725	1,463	1,087
	4,419	2,227	3,423

For the years ended December 31, 2019, 2018 and 2017, US$526,000, US$1,770,000 and US$451,000 were reclassified from liability to additional paid-in capital respectively upon LTIP awards reaching the determination date. As at December 31, 2019 and 2018, US$3,403,000 and US$1,235,000 were recorded as liabilities respectively for LTIP awards prior to the determination date.

As at December 31, 2019, the total unrecognized compensation cost was approximately US$10,808,000, which considers expected performance targets and the amount expected to vest, and will be recognized over the requisite periods.

Notes:

(a) In November 2019, a subsidiary of the Group transferred its 51% shareholding in HSPL to HMPL. Afterwards, the effective equity interest of the Group in HSPL changed to 50.87% as at December 31, 2019.

(b) HHOL and HHOGZL are regarded as subsidiaries of the Company, as while both shareholders of these subsidiaries have equal representation at their respective boards, in the event of a deadlock, the Group has a casting vote and is therefore able to unilaterally control the financial and operating policies of HHOL and HHOGZL.

(c) As at December 31, 2018, the 50% equity interest in NSPL was held by a 99.75% owned subsidiary of the Group. The effective equity interest of the Group in NSPL was therefore 49.88%. In December 2019, the Group acquired the remaining 50% shareholding in NSPL from the equity investee partner for a consideration of approximately US$8.1 million. Afterwards, the effective equity interest of the Group in NSPL changed to 99.75% as at December 31, 2019.

(d) The 50% equity interest in HBYS is held by an 80% owned subsidiary of the Group. The effective equity interest of the Group in HBYS is therefore 40% for the years presented.

Litigation

27. Litigation

From time to time, the Group may become involved in litigation relating to claims arising from the ordinary course of business. The Group believes that there are currently no claims or actions pending against the Group, the ultimate disposition of which could have a material adverse effect on the Group’s results of operations, financial position or cash flows. However, litigation is subject to inherent uncertainties and the Group’s view of these matters may change in the future. When an unfavorable outcome occurs, there exists the possibility of a material adverse impact on the Group’s financial position and results of operations for the periods in which the unfavorable outcome occurs, and potentially in future periods.

On May 17, 2019, Luye Pharma Hong Kong Ltd. (“Luye”) issued a notice to the Group purporting to terminate a distribution agreement that granted the Group exclusive commercial rights to Seroquel in the PRC for failure to meet a pre-specified target. The Group disagrees with this assertion and believes that Luye have no basis for termination. As a result, the Group commenced legal proceedings in 2019 in order to compel Luye to comply with its obligations under the distribution agreement, or alternatively compensate the Group’s damages. The legal proceedings are still in progress. Accordingly, no adjustment has been made to Seroquel-related balances as at December 31, 2019, including accounts receivable, long-term prepayment, accounts payable and other payables of US$1.1 million, US$1.1 million, US$0.9 million and US$1.1 million respectively.

Deferred income tax	1,609	2,000	1,726
Income tax expense	3,274	3,964	3,080

Notes:

(a) The Company, two subsidiaries incorporated in the British Virgin Islands and its Hong Kong subsidiaries are subject to Hong Kong profits tax. In March 2018, the Hong Kong two-tiered profits tax rates regime was signed into law under which the first HK$2.0 million (US$0.3 million) of assessable profits of qualifying corporations will be taxed at 8.25%, with the remaining assessable profits taxed at 16.5%. Hong Kong profits tax has been provided for at the relevant rates on the estimated assessable profits less estimated available tax losses, if any, of these entities as applicable.

(b) Taxation in the PRC has been provided for at the applicable rate on the estimated assessable profits less estimated available tax losses, if any, in each entity. Under the PRC Enterprise Income Tax Law (the “EIT Law”), the standard enterprise income tax (“EIT”) rate is 25%. In addition, the EIT Law provides for, among others, a preferential tax rate of 15% for companies which qualify as HNTE. HMPL and its wholly-owned subsidiary Hutchison MediPharma (Suzhou) Limited qualify as a HNTE up to December 31, 2019 and 2020 respectively.

Pursuant to the EIT law, a 10% withholding tax is levied on dividends paid by PRC companies to their foreign investors. A lower withholding tax rate of 5% is applicable under the China-HK Tax Arrangement if direct foreign investors with at least 25% equity interest in the PRC companies are Hong Kong tax residents, and meet the conditions or requirements pursuant to the relevant PRC tax regulations regarding beneficial ownership. Since the equity holders of the major subsidiaries and equity investees of the Company are Hong Kong incorporated companies and Hong Kong tax residents, and meet the aforesaid conditions or requirements, the Company has used 5% to provide for deferred tax liabilities on retained earnings which are anticipated to be distributed. As at December 31, 2019 and 2018, the amounts accrued in deferred tax liabilities relating to withholding tax on dividends were determined on the basis that 100% of the distributable reserves of the major subsidiaries and equity investees operating in the PRC will be distributed as dividends.

(c) The Company’s subsidiary in the U.S. with operations in New Jersey and New York States is subject to U.S. taxes, primarily federal and state taxes, which have been provided for at approximately 21% (federal) and 9% and 16.55% (New Jersey and New York State respectively) on the estimated assessable profit respectively. Certain income receivable by the Company is subject to U.S. withholding tax of 30%. One of the Group’s subsidiaries is subject to Finland corporate tax at 20% on the estimated assessable profits in relation to its permanent establishment in Finland.

The reconciliation of the Group’s reported income tax expense to the theoretical tax amount that would arise using the tax rates of the Company against the Group’s loss before income taxes and equity in earnings of equity investees is as follows:

	Year Ended December 31,
	2019	2018	2017

(ii)    Deferred tax assets and liabilities

The significant components of deferred tax assets and liabilities are as follows:

	December 31,
	2019	2018
	(in US$’000)
Deferred tax assets
Tax losses	68,481	48,046
Others	1,733	1,555
Total deferred tax assets	70,214	49,601

Deferred tax liabilities
Undistributed earnings from PRC entities	3,081	4,728
Others	77	108
Deferred tax liabilities	3,158	4,836

The movements in deferred tax assets and liabilities are as follows:

	2019	2018	2017
	(in US’000)
As at January 1	(4,256)	(3,819)	(4,989)
Utilization of previously recognized withholding tax on undistributed earnings	3,390	1,373	3,179
(Charged)/Credited to the consolidated statements of operations
Withholding tax on undistributed earnings of PRC entities	(1,894)	(1,983)	(1,980)
Deferred tax on amortization of intangible assets	18	19	18
Deferred tax on provision for assets	267	(36)	236
Exchange differences	132	190	(283)
As at December 31	(2,343)	(4,256)	(3,819)

The deferred tax assets and liabilities are offset when there is a legally enforceable right to set off and when the deferred income taxes relate to the same fiscal authority.

The tax losses can be carried forward against future taxable income and will expire in the following years:

	December 31,
	2019	2018
	(in US$’000)
No expiry date	40,897	52,866
2021	—	9
2022	182	182
2023	—	—
2024	3,716	4,081
2025	35,648	34,319
2026	47,661	48,328
2027	62,794	63,303
2028	106,793	111,753
2029	154,454	—
	452,145	314,841

The Company believes that it is more likely than not that future operations will not generate sufficient taxable income to realize the benefit of the deferred tax assets. The Company’s subsidiaries have had sustained tax losses, which will expire within five years if not utilized in the case of PRC subsidiaries (ten years for HNTEs), and which will not be utilized in the case of Hong Kong subsidiaries as they do not generate taxable profits. Accordingly, a valuation allowance has been recorded against the relevant deferred tax assets arising from the tax losses.

The table below summarizes changes in the deferred tax valuation allowance:

	2019	2018	2017
	(in US$’000)
As at January 1	49,021	31,662	20,145
Charged to consolidated statements of operations	25,498	19,414	11,410
Utilization of previously unrecognized tax losses	(285)	(329)	(387)
Write-off of tax losses	(3,142)	—	(558)
Others	—	(105)	(89)
Exchange differences	(1,693)	(1,621)	1,141
As at December 31	69,399	49,021	31,662

As at December 31, 2019 and 2018, the Group did not have any material unrecognized uncertain tax positions.

(iii)     Income tax payable

	2019	2018	2017
	(in US$’000)
As at January 1	555	979	274
Current tax	1,665	1,964	1,354

Exchange difference	(3)	(9)	8
As at December 31	1,828	555	979

(b) The amount for 2019 excludes the PRC EIT of US$0.3 million prepaid by HSPL which is included under other receivables, prepayments and deposits.

Notes:

(a) Sales of goods are recognized at a point-in-time and sales of services are recognized over time. The implementation of the two-invoice system in China over the periods presented resulted in a shift from a gross sales of goods revenue model to a net fee-for-service revenue model in the Group’s Commercial Platform, as the Group does not obtain control of the goods for distribution for relevant transactions and is thus considered an agent under ASC 606. Refer to Note 3.

(b) Goods— Innovative Medicines and royalties relate to revenue from a prescription drug developed by the Innovation Platform and launched into the market. It was represented under the Commercial Platform due to its transition to the commercial stage for segment reporting. Refer to Note 25.

(c) Under ASC 606, relates to the proportionate amount of milestone payment allocated to the license to the commercialization rights of a drug compound transferred at the inception date of the relevant license and collaboration contract. During the year ended December 31, 2018, the Group received a milestone of US$13.5 million, of which US$12.1 million was allocated to licenses and US$1.4 million was allocated to services.

(d) Under ASC 605, relates to milestone payments recognized under the milestone method.

Notes:

(a) The Company, two subsidiaries incorporated in the British Virgin Islands and its Hong Kong subsidiaries are subject to Hong Kong profits tax. In March 2018, the Hong Kong two-tiered profits tax rates regime was signed into law under which the first HK$2.0 million (US$0.3 million) of assessable profits of qualifying corporations will be taxed at 8.25%, with the remaining assessable profits taxed at 16.5%. Hong Kong profits tax has been provided for at the relevant rates on the estimated assessable profits less estimated available tax losses, if any, of these entities as applicable.

(b) Taxation in the PRC has been provided for at the applicable rate on the estimated assessable profits less estimated available tax losses, if any, in each entity. Under the PRC Enterprise Income Tax Law (the “EIT Law”), the standard enterprise income tax (“EIT”) rate is 25%. In addition, the EIT Law provides for, among others, a preferential tax rate of 15% for companies which qualify as HNTE. HMPL and its wholly-owned subsidiary Hutchison MediPharma (Suzhou) Limited qualify as a HNTE up to December 31, 2019 and 2020 respectively.

Pursuant to the EIT law, a 10% withholding tax is levied on dividends paid by PRC companies to their foreign investors. A lower withholding tax rate of 5% is applicable under the China-HK Tax Arrangement if direct foreign investors with at least 25% equity interest in the PRC companies are Hong Kong tax residents, and meet the conditions or requirements pursuant to the relevant PRC tax regulations regarding beneficial ownership. Since the equity holders of the major subsidiaries and equity investees of the Company are Hong Kong incorporated companies and Hong Kong tax residents, and meet the aforesaid conditions or requirements, the Company has used 5% to provide for deferred tax liabilities on retained earnings which are anticipated to be distributed. As at December 31, 2019 and 2018, the amounts accrued in deferred tax liabilities relating to withholding tax on dividends were determined on the basis that 100% of the distributable reserves of the major subsidiaries and equity investees operating in the PRC will be distributed as dividends.

(c) The Company’s subsidiary in the U.S. with operations in New Jersey and New York States is subject to U.S. taxes, primarily federal and state taxes, which have been provided for at approximately 21% (federal) and 9% and 16.55% (New Jersey and New York State respectively) on the estimated assessable profit respectively. Certain income receivable by the Company is subject to U.S. withholding tax of 30%. One of the Group’s subsidiaries is subject to Finland corporate tax at 20% on the estimated assessable profits in relation to its permanent establishment in Finland.

28. Restricted Net Assets

Relevant PRC laws and regulations permit payments of dividends by the Company’s subsidiaries in the PRC only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company’s subsidiaries in the PRC are required to make certain appropriations of net after-tax profits or increases in net assets to the statutory surplus fund prior to payment of any dividends. In addition, registered share capital and capital reserve accounts are restricted from withdrawal in the PRC, up to the amount of net assets held in each subsidiary. As a result of these and other restrictions under PRC laws and regulations, the Company’s subsidiaries in the PRC are restricted in their ability to transfer their net assets to the Group in terms of cash dividends, loans or advances, with restricted portions amounting to US$0.3 million and US$7.4 million as at December 31, 2019 and 2018 respectively, which excludes the Company’s subsidiaries with a shareholders’ deficit. Even though the Group currently does not require any such dividends, loans or advances from the PRC subsidiaries, for working capital and other funding purposes, the Group may in the future require additional cash resources from the Company’s subsidiaries in the PRC due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends to make distributions to shareholders.

In addition, the Group has certain investments in equity investees in the PRC, where the Group’s equity in undistributed earnings amounted to US$61.6 million and US$92.2 million as at December 31, 2019 and 2018 respectively.

24. Losses per Share

(i)    Basic losses per share

Basic losses per share is calculated by dividing the net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Treasury shares held by the Trustee are excluded from the weighted average number of outstanding ordinary shares in issue for purposes of calculating basic losses per share.

	Year Ended December 31,
	2019	2018	2017
Weighted average number of outstanding ordinary shares in issue	665,683,145	664,263,820	617,171,710
Net loss attributable to the Company (US$’000)	(106,024)	(74,805)	(26,737)
Losses per share attributable to the Company (US$ per share)	(0.16)	(0.11)	(0.04)

(ii)    Diluted losses per share

Diluted losses per share is calculated by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include shares issuable upon the exercise or settlement of share option and LTIP awards issued by the Company using the treasury stock method.

For the years ended December 31, 2019, 2018 and 2017, the share options and LTIP awards issued by the Company were not included in the calculation of diluted losses per share because of their anti-dilutive effect. Therefore, diluted losses per share were equal to basic losses per share for the years ended December 31, 2019, 2018 and 2017.

Notes:

(a) The Company calculated its expected volatility with reference to the historical volatility prior to the issuances of share options.

(b) The risk-free interest rates used in the Polynomial model are with reference to the sovereign yield of the United Kingdom because the Company’s ordinary shares are currently listed on AIM and denominated in £.

(c) The Company has not declared or paid any dividends and does not currently expect to do so in the foreseeable future, and therefore uses an expected dividend yield of zero in the Polynomial model.

Government Incentives

21. Government Incentives

The Group receives government grants from the PRC Government (including the National level and Shanghai Municipal City). Government grants in the Innovation Platform are primarily given in support of Drug R&D activities and are conditional upon i) the Group spending a predetermined amount, regardless of success or failure of the research and development projects and ii) the achievement of certain stages of research and development projects being approved by the relevant PRC government authority. They are refundable to the PRC Government if the conditions, if any, are not met. Government grants in the Commercial Platform are primarily given to promote local initiatives. These government grants may be subject to ongoing reporting and monitoring by the PRC Government over the period of the grant.

Government incentives, which are deferred and recognized in the consolidated statements of operations over the period necessary to match them with the costs that they are intended to compensate, are recognized in other payable, accruals and advance receipts (Note 14) and other non-current liabilities. For the years ended December 31, 2019, 2018 and 2017, the Group received government grants of US$8,742,000, US$1,798,000 and US$1,323,000 respectively.

Notes:

(a) In November 2019, a subsidiary of the Group transferred its 51% shareholding in HSPL to HMPL. Afterwards, the effective equity interest of the Group in HSPL changed to 50.87% as at December 31, 2019.

(b) HHOL and HHOGZL are regarded as subsidiaries of the Company, as while both shareholders of these subsidiaries have equal representation at their respective boards, in the event of a deadlock, the Group has a casting vote and is therefore able to unilaterally control the financial and operating policies of HHOL and HHOGZL.

(c) As at December 31, 2018, the 50% equity interest in NSPL was held by a 99.75% owned subsidiary of the Group. The effective equity interest of the Group in NSPL was therefore 49.88%. In December 2019, the Group acquired the remaining 50% shareholding in NSPL from the equity investee partner for a consideration of approximately US$8.1 million. Afterwards, the effective equity interest of the Group in NSPL changed to 99.75% as at December 31, 2019.

(d) The 50% equity interest in HBYS is held by an 80% owned subsidiary of the Group. The effective equity interest of the Group in HBYS is therefore 40% for the years presented.

Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements reflect the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. Investments in equity investees over which the Group has significant influence are accounted for using the equity method. All inter-company balances and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Additionally, estimates are used in determining items such as useful lives of property, plant and equipment, write-down of inventories, allowance for doubtful accounts, share-based compensation, impairments of long-lived assets, impairment of other intangible asset and goodwill, income tax expenses, tax valuation allowances, revenues and cost accruals from research and development projects. Actual results could differ from those estimates.

Foreign Currency Translation

Foreign Currency Translation

The Company’s presentation currency is the U.S. dollar (“US$”). The financial statements of the Company and its subsidiaries with a functional currency other than the US$ have been translated into the Company’s presentation currency. All assets and liabilities of the subsidiaries are translated using year-end exchange rates and revenues and expenses are translated at average exchange rates for the year. Translation adjustments are reflected in accumulated other comprehensive (loss)/income in shareholders’ equity.

Net foreign currency exchange gains of US$246,000 and net foreign exchanges losses of US$233,000 and US$316,000 were recorded in other income and other expense in the consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017 respectively.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Group considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of cash on hand and bank deposits and are stated at cost, which approximates fair value.

Short-term Investments

Short-term Investments

Short-term investments include deposits placed with banks with original maturities of more than three months but less than one year.

Concentration of Credit Risk

Concentration of Credit Risk

Financial instruments that potentially expose the Group to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, accounts receivable, other receivables and amounts due from related parties.

The Group places substantially all of its cash and cash equivalents and short-term investments in major financial institutions, which management believes are of high credit quality. The Group has a practice to limit the amount of credit exposure to any particular financial institution.

The Group has no significant concentration of credit risk. The Group has policies in place to ensure that sales are made to customers with an appropriate credit history and the Group performs periodic credit evaluations of its customers. Normally the Group does not require collateral from trade debtors.

Foreign Currency Risk

Foreign Currency Risk

The Group’s operating transactions and its assets and liabilities  in the PRC are mainly denominated in Renminbi (“RMB”), which is not freely convertible into foreign currencies. The Group’s cash and cash equivalents denominated in RMB are subject to government controls. The value of the RMB is subject to fluctuations from central government policy changes and international economic and political developments that affect the supply and demand of RMB in the foreign exchange market. In the PRC, certain foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China (the “PBOC”). Remittances in currencies other than RMB by the Group in the PRC must be processed through the PBOC or other PRC foreign exchange regulatory bodies which require certain supporting documentation in order to complete the remittance.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The fair value of financial instruments that are measured at fair value is determined according to a fair value hierarchy that prioritizes the inputs and assumptions used, and the valuation techniques used. The three levels of the fair value hierarchy are described as follows:

Level 1	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2	Inputs are quoted prices for similar assets or liabilities in active markets; or quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
Level 3	Inputs are unobservable inputs based on the Group’s assumptions and valuation techniques used to measure assets or liabilities at fair value. The inputs require significant management judgment or estimation.

The assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels.

The fair value of assets and liabilities is established using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, and a fair value hierarchy is established based on the inputs used to measure fair value.

Accounts Receivable

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from customers based on their outstanding invoices. Management reviews accounts receivable regularly to determine if any receivable will potentially be uncollectible. Estimates are used to determine the amount of allowance for doubtful accounts necessary to reduce accounts receivable to its estimated net realizable value. The amount of the allowance for doubtful accounts is recognized in the consolidated statements of operations.

Inventories

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. A provision for excess and obsolete inventory will be made based primarily on forecasts of product demand and production requirements. The excess balance determined by this analysis becomes the basis for excess inventory charge and the written-down value of the inventory becomes its cost. Written-down inventory is not written up if market conditions improve.

Property, Plant and Equipment

Property, Plant and Equipment

Property, plant and equipment consist of buildings, leasehold improvements, plant and equipment, furniture and fixtures, other equipment and motor vehicles. Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets.

Buildings	20 years
Plant and equipment	5-10 years
Furniture and fixtures, other equipment and motor vehicles	4-5 years
Leasehold improvements	Shorter of (a) 5 years or (b) remaining term of lease

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the consolidated statements of operations in the year of disposition. Additions and improvements that extend the useful life of an asset are capitalized. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

The Group evaluates the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets. The Group evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. If such indicators exist, the first step of the impairment test is performed to assess if the carrying value of the net assets exceeds the undiscounted cash flows of the assets. If yes, the second step of the impairment test is performed in order to determine if the carrying value of the net assets exceeds the fair value. If yes, impairment is recognized for the excess.

Leasehold Land

Leasehold Land

Leasehold land represents fees paid to acquire the right to use the land on which various plants and buildings are situated for a specified period of time from the date the respective right was granted and are stated at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the lease period of 50 years.

Goodwill

Goodwill

Goodwill represents the excess of the purchase price plus fair value of non-controlling interests over the fair value of identifiable assets and liabilities acquired. Goodwill is not amortized, but is tested for impairment at the reporting unit level on at least an annual basis or when an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When performing an evaluation of goodwill impairment, the Group has the option to first assess qualitative factors, such as significant events and changes to expectations and activities that may have occurred since the last impairment evaluation, to determine if it is more likely than not that goodwill might be impaired. If as a result of the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the quantitative fair value test is performed to determine if the fair value of the reporting unit exceeds its carrying value.

Other Intangible Assets

Other Intangible Assets

Other intangible assets with finite useful lives are carried at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the estimated useful lives of the assets.

Borrowings

Borrowings

Borrowings are recognized initially at fair value, net of debt issuance costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of debt issuance costs) and the redemption value is recognized in the consolidated statements of operations over the period of the borrowings using the effective interest method.

Ordinary Shares

Ordinary Shares

The Company’s ordinary shares are stated at par value of US$0.10 per ordinary share. The difference between the consideration received, net of issuance cost, and the par value is recorded in additional paid-in capital.

Treasury Shares

Treasury Shares

The Group accounts for treasury shares under the cost method. The treasury shares are purchased for the purpose of the LTIP and held by a trustee appointed by the Group (the “Trustee”) prior to vesting.

Share-Based Compensation

Share-Based Compensation

Share options

The Group recognizes share-based compensation expense on share options granted to employees and directors based on their estimated grant date fair value using the Polynomial model. This Polynomial pricing model uses various inputs to measure fair value, including estimated market value of the Company’s underlying ordinary shares at the grant date, contractual terms, estimated volatility, risk-free interest rates and expected dividend yields. The Group recognizes share-based compensation expense in the consolidated statements of operations on a graded vesting basis over the requisite service period, and accounts for forfeitures as they occur.

Share options are classified as equity-settled awards. Share-based compensation expense, when recognized, is charged to the consolidated statements of operations with the corresponding entry to additional paid-in capital.

LTIP

The Group recognizes the share-based compensation expense on the LTIP awards based on a fixed or determinable monetary amount on a straight-line basis for each annual tranche awarded over the requisite period. For LTIP awards with performance targets, prior to their determination date, the amount of LTIP awards that is expected to vest takes into consideration the achievement of the performance conditions and the extent to which the performance conditions are likely to be met. Performance conditions vary by awards, including targets for shareholder returns, free cash flows, revenues, net profit after taxes and/or the achievement of clinical and regulatory milestones.

These LTIP awards are classified as liability-settled awards before the determination date (i.e. the date when the achievement of any performance conditions are known), as they settle in a variable number of shares based on a determinable monetary amount, which is determined upon the actual achievement of performance targets. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management’s assessment of the achievement of the performance targets has been assigned to calculate the amount to be recognized as an expense over the requisite period.

After the determination date or if the LTIP awards have no performance conditions, the LTIP awards are classified as equity-settled awards. If the performance target is achieved, the Group will pay the determined monetary amount to the Trustee to purchase ordinary shares of the Company or the equivalent ADS. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no ordinary shares or ADS of the Company will be purchased and the amount previously recorded in the liability will be reversed and included in the consolidated statements of operations.

Defined Contribution Plans

Defined Contribution Plans

The Group’s subsidiaries in the PRC participate in a government-mandated multi-employer defined contribution plan pursuant to which certain retirement, medical and other welfare benefits are provided to employees. The relevant labor regulations require the Group’s subsidiaries in the PRC to pay the local labor and social welfare authority’s monthly contributions at a stated contribution rate based on the monthly basic compensation of qualified employees. The relevant local labor and social welfare authorities are responsible for meeting all retirement benefits obligations and the Group’s subsidiaries in the PRC have no further commitments beyond their monthly contributions. The contributions to the plan are expensed as incurred.

The Group also makes payments to other defined contribution plans for the benefit of employees employed by subsidiaries outside the PRC. The defined contribution plans are generally funded by the relevant companies and by payments from employees.

The Group’s contributions to defined contribution plans for the years ended December 31, 2019, 2018 and 2017 amounted to US$3,479,000, US$2,878,000 and US$2,092,000 respectively.

Revenue Recognition

Revenue Recognition

Summary of impact of applying Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (Topic 606) (“ASC 606”)

The Group applied ASC 606 to all contracts at the date of initial application of January 1, 2018. As a result, the Group has changed its accounting policy for revenue recognition as detailed below. The Group applied ASC 606 using the modified retrospective method by recognizing the cumulative effect as an adjustment to opening accumulated losses at January 1, 2018. The comparative information prior to January 1, 2018 has not been adjusted and continues to be reported under ASC 605, Revenue Recognition (Topic 605) (“ASC 605”).

The Group assessed its license and collaboration contracts under ASC 606. Refer to Note 19. As a result of this assessment, the Group recorded an aggregate US$1.1 million deferral of revenue as a cumulative adjustment to opening accumulated losses upon adoption.

For sales of goods and services, the Group applied a portfolio approach to aggregate contracts into portfolios whose performance obligations do not differ materially from each other. In its assessment of each portfolio, the Group assessed the contracts under the new five-step model under ASC 606 and determined there was no significant impact to the timing or amount of revenue recognition under the new guidance.

Under the Group’s previous accounting policy, deferred revenue comprised deferred upfront payments from the Group’s license and collaboration contracts. Under ASC 606, advance payments from customers preceding an entity’s performance are considered contract liabilities; therefore, advance payments from customers from the Group’s Commercial Platform have been reclassified from other payables, accruals and advance receipts to deferred revenue. Expected rebates for sales of goods remain in other payables, accruals and advance receipts.

The following tables summarize the impact of adopting ASC 606 on the Group’s consolidated financial statements as at and for the year ended December 31, 2018, as compared to the amounts as if applying ASC 605:

Accounting policy—ASC 606

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Group from a customer, are also excluded from revenue. The Group recognizes revenue when it satisfies a performance obligation by transferring control over a good, service or license to a customer.

Nature of goods and services

The following is a description of principal activities, separated by reportable segments, from which the Company generates its revenue:

(i)    Innovation Platform

The Innovation Platform reportable segment principally generates revenue from license and collaboration contracts. The license and collaboration contracts generally contain multiple performance obligations including (1) the license to the commercialization rights of a drug compound and (2) the research and development services for each specified treatment indication, which are accounted for separately if they are distinct, i.e. if a product or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer.

The transaction price generally includes fixed and variable consideration in the form of upfront payment, research and development cost reimbursements, contingent milestone payments and sales-based royalties. Contingent milestone payments are not included in the transaction price until it becomes probable that a significant reversal of revenue will not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation is based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. The Group estimates the standalone selling prices based on the income approach. Control of the license to the drug compounds transfers at the inception date of the collaboration agreements and consequently, amounts allocated to this performance obligation are generally recognized at a point in time. Conversely, research and development services for each specified indication are performed over time and amounts allocated to these performance obligations are generally recognized over time using cost inputs as a measure of progress. The Group has determined that research and development expenses provide an appropriate depiction of measure of progress for the research and development services. Changes to estimated cost inputs may result in a cumulative catch-up adjustment. Royalty revenues are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception, and are included in Commercial Platform revenues.

Deferred revenue is recognized if allocated consideration is received in advance of the Group rendering research and development services. Accounts receivable is recognized based on the terms of the contract and when the Group has an unconditional right to bill the customer, which is generally when research and development services are rendered.

(ii)    Commercial Platform

The Commercial Platform reportable segment principally generates revenue from (1) sales of goods, which are the manufacture or purchase and distribution of products including a prescription drug product developed by the Innovation Platform and other consumer health products, (2) royalty revenues from license and collaboration contracts and (3) sales of services, which are the provision of sales, distribution and marketing services to pharmaceutical manufacturers. The Group evaluates whether it is the principal or agent for these contracts, which include prescription drug products and consumer health products. Where the Group obtains control of the goods for distribution, it is the principal (i.e. recognizes sales of goods on a gross basis). Where the Group does not obtain control of the goods for distribution, it is the agent (i.e. recognizes provision of services on a net basis). Control is primarily evidenced by taking physical possession and inventory risk of the goods.

Revenue from sales of goods is recognized when the customer takes possession of the goods. This usually occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, the Group recognizes revenue from provision of services based on amounts that can be invoiced to the customer.

Deferred revenue is recognized if consideration is received in advance of transferring control of the goods or rendering of services. Accounts receivable is recognized if the Group has an unconditional right to bill the customer, which is generally when the customer takes possession of the goods or services are rendered. Payment terms differ by subsidiary and customer, but generally range from 45 to 180 days from the invoice date.

Prior accounting policy—ASC 605

Sales

Revenue from sales of goods in the Commercial Platform segment are recognized when goods are delivered and title passes to the customer and there are no further obligations to the customer. Recognition of revenue also requires reasonable assurance of collection of sales proceeds and completion of all performance obligations. Sales discounts are issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from sales of services in the Commercial Platform segment are recognized based on amounts that can be invoiced to the customer. The amount that can be invoiced corresponds directly with the value to the customer for performance completed to date.

Revenues from research and development projects

The Group recognizes revenue for the performance of services when each of the following four criteria are met: (i) persuasive evidence of an arrangement exists; (ii) services are rendered; (iii) the sales price is fixed or determinable; and (iv) collectability is reasonably assured.

The Group follows ASC 605-25, Revenue Recognition—Multiple-Element Arrangements and ASC 808, Collaborative Arrangements, if applicable, to determine the recognition of revenue under the Group’s license and collaborative research, development and commercialization agreements. The terms of these agreements generally contain multiple elements, or deliverables, which may include (i) licenses to the Group’s intellectual property, (ii) materials and technology, (iii) clinical supply, and/or (iv) participation in joint research or joint steering committees. The payments the Group may receive under these arrangements typically include one or more of the following: non-refundable, upfront license fees; funding of research and/or development efforts; amounts due upon the achievement of specified milestones; and/or royalties on future product sales.

ASC 605-25 provides guidance relating to the separability of deliverables included in an arrangement into different units of accounting and the allocation of arrangement consideration to the units of accounting. The evaluation of multiple-element arrangements requires management to make judgments about (i) the identification of deliverables, (ii) whether such deliverables are separable from the other aspects of the contractual relationship, (iii) the estimated selling price of each deliverable, and (iv) the expected period of performance for each deliverable.

To determine the units of accounting under a multiple-element arrangement, management evaluates certain separation criteria, including whether the deliverables have stand-alone value, based on the relevant facts and circumstances for each arrangement. Management then estimates the selling price for each unit of accounting and allocates the arrangement consideration to each unit utilizing the relative selling price method. The Group determines the estimated selling price for deliverables within each agreement using vendor-specific objective evidence (“VSOE”) of selling price, if available, or third party evidence of selling price if VSOE is not available, or the Group’s best estimate of selling price, if neither VSOE nor third party evidence is available. Determining the best estimate of selling price for a deliverable requires significant judgment. The Group typically uses its best estimate of a selling price to estimate the selling price for licenses to development work, since it often does not have VSOE or third party evidence of selling price for these deliverables. In those circumstances where the Group applies its best estimate of selling price to determine the estimated selling price of a license to development work, it considers market conditions as well as entity-specific factors, including those factors contemplated in negotiating the agreements as well as internally developed estimates that include assumptions related to the market opportunity, estimated development costs, probability of success and the time needed to commercialize a product candidate pursuant to the license. In validating its best estimate of selling price, the Group evaluates whether changes in the key assumptions used to determine its best estimate of selling price will have a significant effect on the allocation of arrangement consideration between deliverables. The Group recognizes consideration allocated to an individual element when all other revenue recognition criteria are met for that element.

The allocated consideration for each unit of accounting is recognized over the related obligation period in accordance with the applicable revenue recognition criteria.

If there are deliverables in an arrangement that are not separable from other aspects of the contractual relationship, they are treated as a combined unit of accounting, with the allocated revenue for the combined unit recognized in a manner consistent with the revenue recognition applicable to the final deliverable in the combined unit. Payments received prior to satisfying the relevant revenue recognition criteria are recorded as unearned revenue in the accompanying balance sheets and recognized as revenue when the related revenue recognition criteria are met.

The Group typically receives non-refundable, upfront payments when licensing the Group’s intellectual property, which often occurs in conjunction with a research and development agreement. If management believes that the license to the Group’s intellectual property has stand-alone value, the Group generally recognizes revenue attributed to the license upon delivery provided that there are no future performance requirements for use of the license. When management believes that the license to the Group’s intellectual property does not have stand-alone value, the Group will recognize revenue attributed to the license ratably over the contractual or estimated performance period. For payments payable on achievement of milestones that do not meet all of the conditions to be considered substantive, the Group recognizes a portion of the payment as revenue when the specific milestone is achieved, and the contingency is removed. Other contingent event-based payments for which payment is either contingent solely upon the passage of time or the result of a collaborator’s performance are recognized when earned. The Group’s collaboration and license agreements generally include contingent milestone payments related to specified pre-clinical research and development milestones, clinical development milestones, regulatory milestones and sales-based milestones. Pre-clinical research and development milestones are typically payable upon the selection of a compound candidate for the next stage of research and development. Clinical development milestones are typically payable when a product candidate initiates or advances in clinical trial phases or achieves defined clinical events such as proof-of-concept. Regulatory milestones are typically payable upon submission for marketing approval with regulatory authorities or upon receipt of actual marketing approvals for a compound, approvals for additional indications, or upon the first commercial sale. Sales-based milestones are typically payable when annual sales reach specified levels.

At the inception of each arrangement that includes milestone payments, the Group evaluates whether each milestone is substantive and at risk to both parties on the basis of the contingent nature of the milestone. This evaluation includes an assessment of whether (a) the consideration is commensurate with either (i) the entity’s performance to achieve the milestone or (ii) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone; (b) the consideration relates solely to past performance; and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Group evaluates factors such as the scientific, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required to achieve the respective milestone and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment.

Research and Development Expenses

Research and Development Expenses

Research and development expenses consist primarily of salaries and benefits, share-based compensation, materials and supplies, contracted research, consulting arrangements and other expenses incurred to sustain the Group’s research and development programs. Research and development costs are expensed as incurred.

Government Incentives

Government Incentives

Incentives from governments are recognized at their fair values. Government incentives that are received in advance are deferred and recognized in the consolidated statements of operations over the period necessary to match them with the costs that they are intended to compensate. Government incentives in relation to the achievement of stages of research and development projects are recognized in the consolidated statements of operations when amounts have been received and all attached conditions have been met. Non-refundable incentives received without any further obligations or conditions attached are recognized immediately in the consolidated statements of operations.

Leases

Leases

Summary of impact of applying ASC 842

The Group applied ASC 842 to its various leases at the date of initial application of January 1, 2019. As a result, the Group has changed its accounting policy for leases as detailed below. The core principle of ASC 842 is that a lessee should recognize the assets and liabilities that arise from leases. Therefore, the Group recognizes in the consolidated balance sheets liabilities to make lease payments (the lease liabilities) and right-of-use assets representing its right to use the underlying assets for their lease terms. The Group applied ASC 842 using the optional transition method by recognizing the cumulative effect as an adjustment to opening accumulated losses as at January 1, 2019. The comparative information prior to January 1, 2019 has not been adjusted and continues to be reported under ASC 840, Leases (“ASC 840”).

The Group assessed lease agreements as at January 1, 2019 under ASC 842, except for short-term leases. The Group elected the short-term lease exception for leases with a term of 12 months or less and recognizes lease expenses for such leases on a straight-line basis over the lease term and does not recognize right-of-use assets or lease liabilities accordingly. As a result of this assessment, the Group recorded an aggregate US$0.7 million in additional lease expenses as a cumulative adjustment to opening accumulated losses upon adoption. Additionally, the Group recognized right-of-use assets and lease liabilities of US$5.7 million and US$6.4 million respectively as at January 1, 2019.

The lease liabilities were measured at the present value of the remaining lease payments, discounted using the lessees’ incremental borrowing rate as at January 1, 2019. The Group’s weighted average incremental borrowing rate applied on January 1, 2019 was 3.97% per annum.

A reconciliation of the Group’s reported operating lease commitments as at December 31, 2018 and the Group’s lease liabilities recognized upon adoption of ASC 842 as at January 1, 2019 is as follows:

	(in US$’000)
Operating lease commitments as at December 31, 2018 (note (a))	8,835
Less: Leases not commenced as at January 1, 2019	(3,676)
Less: Short‑term leases	(5)
Add: Adjustment as a result of the treatment for a termination option (note (b))	1,409
Less: Discount under the lessees’ incremental borrowing rate as at January 1, 2019	(206)
Lease liabilities recognized as at January 1, 2019	6,357

Notes:

(a) Future aggregate minimum payments under non-cancellable operating leases under ASC 840 were as follows:

	December 31,
	2018
	(in US$’000)
Not later than 1 year	3,026
Between 1 to 2 years	2,735
Between 2 to 3 years	1,056
Between 3 to 4 years	882
Between 4 to 5 years	810
Later than 5 years	326
Total minimum lease payments	8,835

(b) The Group leases its corporate offices in Hong Kong through a support service agreement with an indirect subsidiary of CK Hutchison Holdings Limited (“CK Hutchison”), which is the Company’s indirect major shareholder. The support service agreement may be terminated by giving 3-month advance notice; therefore, there was no lease commitment beyond the 3-month advance notice period as at December 31, 2018. This termination option is not considered probable of exercise for the purposes of applying ASC 842.

The Group recognized right-of-use assets as at January 1, 2019 measured at their carrying amounts as if ASC 842 had been applied since their commencement dates, but discounted using the lessees’ incremental borrowing rate as at January 1, 2019.

Recognized right-of-use assets upon adoption were as follows:

	(in US$’000)
Offices	4,877
Factories	383
Others	487
	5,747

There were no adjustments to net cash generated from/(used in) operating activities, investing activities or financing activities in the consolidated statement of cash flows.

In applying ASC 842 for the first time, the Group has used the following practical expedients permitted by the standard: (i) no reassessment of whether any expired or existing contracts are or contain leases; (ii) no reassessment of the lease classification for any expired or existing leases; (iii) the exclusion of initial direct costs for the measurement of the right-of-use assets at the date of initial application; and (iv) the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

Updated accounting policy—ASC 842

In an operating lease, a lessee obtains control of only the use of the underlying asset, but not the underlying asset itself. An operating lease is recognized as a right-of-use asset with a corresponding liability at the date which the leased asset is available for use by the Group. The Group recognizes an obligation to make lease payments equal to the present value of the lease payments over the lease term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.

Lease liabilities include the net present value of the following lease payments: (i) fixed payments; (ii) variable lease payments; and (iii) payments of penalties for terminating the lease if the lease term reflects the lessee exercising that option, if any. Lease liabilities exclude the following payments that are generally accounted for separately: (i) non-lease components, such as maintenance and security service fees and value added tax, and (ii) any payments that a lessee makes before the lease commencement date. The lease payments are discounted using the interest rate implicit in the lease or if that rate cannot be determined, the lessee’s incremental borrowing rate being the rate that the lessee would have to pay to borrow the funds in its currency and jurisdiction necessary to obtain an asset of similar value, economic environment and terms and conditions.

An asset representing the right to use the underlying asset during the lease term is recognized that consists of the initial measurement of the operating lease liability, any lease payments made to the lessor at or before the commencement date less any lease incentives received, any initial direct cost incurred by the Group and any restoration costs.

After commencement of the operating lease, the Group recognizes lease expenses on a straight-line basis over the lease term. The right-of-use asset is subsequently measured at cost less accumulated amortization and any impairment provision. The amortization of the right-of-use asset represents the difference between the straight-line lease expense and the accretion of interest on the lease liability each period. The interest amount is used to accrete the lease liability and to amortize the right-of-use asset. There is no amount recorded as interest expense.

Payments associated with short-term leases are recognized as lease expenses on a straight-line basis over the period of the leases.

Subleases of right-of-use assets are accounted for similar to other leases. As an intermediate lessor, the Group separately accounts for the head-lease and sublease unless it is relieved of its primary obligation under the head-lease. Sublease income is recorded on a gross basis separate from the head-lease expenses. If the total remaining lease cost on the head-lease is more than the anticipated sublease income for the lease term, this is an indicator that the carrying amount of the right-of-use asset associated with the head-lease may not be recoverable, and the right-of-use asset will be assessed for impairment.

Prior accounting policy - ASC 840

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the period of the leases.

Total operating lease rentals for factories and offices for the years ended December 31, 2018 and  2017 amounted to US$3,759,000 and US$2,285,000 respectively. Sublease rentals for the years ended December 31, 2018 and 2017 amounted to US$254,000 and US$274,000 respectively.

Interest Income

Interest Income

Interest generated from cash and cash equivalents and short-term investments is recorded over the period earned. It is measured based on the actual amount of interest the Group earns.

Income Taxes

Income Taxes

The Group accounts for income taxes under the liability method. Under the liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the income tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of the net deferred income tax asset will not be realized.

The Group accounts for an uncertain tax position in the consolidated financial statements only if it is more likely than not that the position is sustainable based on its technical merits and consideration of the relevant tax authority’s widely understood administrative practices and precedents. If the recognition threshold is met, the Group records the largest amount of  tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement.

The Group recognizes interest and penalties for income taxes, if any, under income tax payable on its consolidated balance sheets and under other expenses in its consolidated statements of operations.

Comprehensive Loss

Comprehensive Loss

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions, and other events and circumstances from non-owner sources, and currently consists of net loss and foreign currency translation (loss)/gain related to the Company’s subsidiaries.

Losses per Share

Losses per Share

Basic losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Weighted average number of outstanding ordinary shares in issue excludes treasury shares.

Diluted losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include ordinary shares and treasury shares issuable upon the exercise or settlement of share-based awards issued by the Company using the treasury stock method. The computation of diluted losses per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect.

Segment Reporting

Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief executive officer who is the Group’s chief operating decision maker. The chief operating decision maker reviews the Group’s internal reporting in order to assess performance and allocate resources and determined that the Group’s reportable segments are as disclosed in Note 25.

Profit Appropriation and Statutory Reserves

Profit Appropriation and Statutory Reserves

The Group’s subsidiaries and equity investees established in the PRC are required to make appropriations to certain non-distributable reserve funds.

In accordance with the relevant laws and regulations established in the PRC, the Company’s subsidiaries registered as wholly-owned foreign enterprise have to make appropriations from their after-tax profits (as determined under generally accepted accounting principles in the PRC (“PRC GAAP”)) to reserve funds including general reserve fund, enterprise expansion fund and staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the company. Appropriations to the enterprise expansion fund and staff bonus and welfare fund are made at the respective company’s discretion. For the Group’s equity investees, the amount of appropriations to these funds are made at the discretion of their respective boards.

In addition, Chinese domestic companies must make appropriations from their after-tax profits as determined under PRC GAAP to non-distributable reserve funds including statutory surplus fund and discretionary surplus fund. The appropriation to the statutory surplus fund must be 10% of the after-tax profits as determined under PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the company. Appropriation to the discretionary surplus fund is made at the respective company’s discretion.

The use of the general reserve fund, enterprise expansion fund, statutory surplus fund and discretionary surplus fund is restricted to the offsetting of losses or increases to the registered capital of the respective company. The staff bonus and welfare fund is a liability in nature and is restricted to fund payments of special bonus to employees and for the collective welfare of employees. All these reserves are not permitted to be transferred to the company as cash dividends, loans or advances, nor can they be distributed except under liquidation.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including accounts receivable and other receivables. The Group currently does not expect ASU 2016-13 to have a material impact to the Group’s consolidated financial statements.

Amendments that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Group’s consolidated financial statements upon adoption.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

3. Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements reflect the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. Investments in equity investees over which the Group has significant influence are accounted for using the equity method. All inter-company balances and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Additionally, estimates are used in determining items such as useful lives of property, plant and equipment, write-down of inventories, allowance for doubtful accounts, share-based compensation, impairments of long-lived assets, impairment of other intangible asset and goodwill, income tax expenses, tax valuation allowances, revenues and cost accruals from research and development projects. Actual results could differ from those estimates.

Foreign Currency Translation

The Company’s presentation currency is the U.S. dollar (“US$”). The financial statements of the Company and its subsidiaries with a functional currency other than the US$ have been translated into the Company’s presentation currency. All assets and liabilities of the subsidiaries are translated using year-end exchange rates and revenues and expenses are translated at average exchange rates for the year. Translation adjustments are reflected in accumulated other comprehensive (loss)/income in shareholders’ equity.

Net foreign currency exchange gains of US$246,000 and net foreign exchanges losses of US$233,000 and US$316,000 were recorded in other income and other expense in the consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017 respectively.

Cash and Cash Equivalents

The Group considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of cash on hand and bank deposits and are stated at cost, which approximates fair value.

Short-term Investments

Short-term investments include deposits placed with banks with original maturities of more than three months but less than one year.

Concentration of Credit Risk

Financial instruments that potentially expose the Group to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, accounts receivable, other receivables and amounts due from related parties.

The Group places substantially all of its cash and cash equivalents and short-term investments in major financial institutions, which management believes are of high credit quality. The Group has a practice to limit the amount of credit exposure to any particular financial institution.

The Group has no significant concentration of credit risk. The Group has policies in place to ensure that sales are made to customers with an appropriate credit history and the Group performs periodic credit evaluations of its customers. Normally the Group does not require collateral from trade debtors.

Foreign Currency Risk

The Group’s operating transactions and its assets and liabilities  in the PRC are mainly denominated in Renminbi (“RMB”), which is not freely convertible into foreign currencies. The Group’s cash and cash equivalents denominated in RMB are subject to government controls. The value of the RMB is subject to fluctuations from central government policy changes and international economic and political developments that affect the supply and demand of RMB in the foreign exchange market. In the PRC, certain foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China (the “PBOC”). Remittances in currencies other than RMB by the Group in the PRC must be processed through the PBOC or other PRC foreign exchange regulatory bodies which require certain supporting documentation in order to complete the remittance.

Fair Value of Financial Instruments

The fair value of financial instruments that are measured at fair value is determined according to a fair value hierarchy that prioritizes the inputs and assumptions used, and the valuation techniques used. The three levels of the fair value hierarchy are described as follows:

Level 1	Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2	Inputs are quoted prices for similar assets or liabilities in active markets; or quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.
Level 3	Inputs are unobservable inputs based on the Group’s assumptions and valuation techniques used to measure assets or liabilities at fair value. The inputs require significant management judgment or estimation.

The assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels.

The fair value of assets and liabilities is established using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, and a fair value hierarchy is established based on the inputs used to measure fair value.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from customers based on their outstanding invoices. Management reviews accounts receivable regularly to determine if any receivable will potentially be uncollectible. Estimates are used to determine the amount of allowance for doubtful accounts necessary to reduce accounts receivable to its estimated net realizable value. The amount of the allowance for doubtful accounts is recognized in the consolidated statements of operations.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. A provision for excess and obsolete inventory will be made based primarily on forecasts of product demand and production requirements. The excess balance determined by this analysis becomes the basis for excess inventory charge and the written-down value of the inventory becomes its cost. Written-down inventory is not written up if market conditions improve.

Property, Plant and Equipment

Property, plant and equipment consist of buildings, leasehold improvements, plant and equipment, furniture and fixtures, other equipment and motor vehicles. Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets.

Buildings	20 years
Plant and equipment	5-10 years
Furniture and fixtures, other equipment and motor vehicles	4-5 years
Leasehold improvements	Shorter of (a) 5 years or (b) remaining term of lease

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the consolidated statements of operations in the year of disposition. Additions and improvements that extend the useful life of an asset are capitalized. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

The Group evaluates the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets. The Group evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. If such indicators exist, the first step of the impairment test is performed to assess if the carrying value of the net assets exceeds the undiscounted cash flows of the assets. If yes, the second step of the impairment test is performed in order to determine if the carrying value of the net assets exceeds the fair value. If yes, impairment is recognized for the excess.

Leasehold Land

Leasehold land represents fees paid to acquire the right to use the land on which various plants and buildings are situated for a specified period of time from the date the respective right was granted and are stated at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the lease period of 50 years.

Goodwill

Goodwill represents the excess of the purchase price plus fair value of non-controlling interests over the fair value of identifiable assets and liabilities acquired. Goodwill is not amortized, but is tested for impairment at the reporting unit level on at least an annual basis or when an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When performing an evaluation of goodwill impairment, the Group has the option to first assess qualitative factors, such as significant events and changes to expectations and activities that may have occurred since the last impairment evaluation, to determine if it is more likely than not that goodwill might be impaired. If as a result of the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the quantitative fair value test is performed to determine if the fair value of the reporting unit exceeds its carrying value.

Other Intangible Assets

Other intangible assets with finite useful lives are carried at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the estimated useful lives of the assets.

Borrowings

Borrowings are recognized initially at fair value, net of debt issuance costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of debt issuance costs) and the redemption value is recognized in the consolidated statements of operations over the period of the borrowings using the effective interest method.

Ordinary Shares

The Company’s ordinary shares are stated at par value of US$0.10 per ordinary share. The difference between the consideration received, net of issuance cost, and the par value is recorded in additional paid-in capital.

Treasury Shares

The Group accounts for treasury shares under the cost method. The treasury shares are purchased for the purpose of the LTIP and held by a trustee appointed by the Group (the “Trustee”) prior to vesting.

Share-Based Compensation

Share options

The Group recognizes share-based compensation expense on share options granted to employees and directors based on their estimated grant date fair value using the Polynomial model. This Polynomial pricing model uses various inputs to measure fair value, including estimated market value of the Company’s underlying ordinary shares at the grant date, contractual terms, estimated volatility, risk-free interest rates and expected dividend yields. The Group recognizes share-based compensation expense in the consolidated statements of operations on a graded vesting basis over the requisite service period, and accounts for forfeitures as they occur.

Share options are classified as equity-settled awards. Share-based compensation expense, when recognized, is charged to the consolidated statements of operations with the corresponding entry to additional paid-in capital.

LTIP

The Group recognizes the share-based compensation expense on the LTIP awards based on a fixed or determinable monetary amount on a straight-line basis for each annual tranche awarded over the requisite period. For LTIP awards with performance targets, prior to their determination date, the amount of LTIP awards that is expected to vest takes into consideration the achievement of the performance conditions and the extent to which the performance conditions are likely to be met. Performance conditions vary by awards, including targets for shareholder returns, free cash flows, revenues, net profit after taxes and/or the achievement of clinical and regulatory milestones.

These LTIP awards are classified as liability-settled awards before the determination date (i.e. the date when the achievement of any performance conditions are known), as they settle in a variable number of shares based on a determinable monetary amount, which is determined upon the actual achievement of performance targets. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management’s assessment of the achievement of the performance targets has been assigned to calculate the amount to be recognized as an expense over the requisite period.

After the determination date or if the LTIP awards have no performance conditions, the LTIP awards are classified as equity-settled awards. If the performance target is achieved, the Group will pay the determined monetary amount to the Trustee to purchase ordinary shares of the Company or the equivalent ADS. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no ordinary shares or ADS of the Company will be purchased and the amount previously recorded in the liability will be reversed and included in the consolidated statements of operations.

Defined Contribution Plans

The Group’s subsidiaries in the PRC participate in a government-mandated multi-employer defined contribution plan pursuant to which certain retirement, medical and other welfare benefits are provided to employees. The relevant labor regulations require the Group’s subsidiaries in the PRC to pay the local labor and social welfare authority’s monthly contributions at a stated contribution rate based on the monthly basic compensation of qualified employees. The relevant local labor and social welfare authorities are responsible for meeting all retirement benefits obligations and the Group’s subsidiaries in the PRC have no further commitments beyond their monthly contributions. The contributions to the plan are expensed as incurred.

The Group also makes payments to other defined contribution plans for the benefit of employees employed by subsidiaries outside the PRC. The defined contribution plans are generally funded by the relevant companies and by payments from employees.

The Group’s contributions to defined contribution plans for the years ended December 31, 2019, 2018 and 2017 amounted to US$3,479,000, US$2,878,000 and US$2,092,000 respectively.

Revenue Recognition

Summary of impact of applying Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (Topic 606) (“ASC 606”)

The Group applied ASC 606 to all contracts at the date of initial application of January 1, 2018. As a result, the Group has changed its accounting policy for revenue recognition as detailed below. The Group applied ASC 606 using the modified retrospective method by recognizing the cumulative effect as an adjustment to opening accumulated losses at January 1, 2018. The comparative information prior to January 1, 2018 has not been adjusted and continues to be reported under ASC 605, Revenue Recognition (Topic 605) (“ASC 605”).

The Group assessed its license and collaboration contracts under ASC 606. Refer to Note 19. As a result of this assessment, the Group recorded an aggregate US$1.1 million deferral of revenue as a cumulative adjustment to opening accumulated losses upon adoption.

For sales of goods and services, the Group applied a portfolio approach to aggregate contracts into portfolios whose performance obligations do not differ materially from each other. In its assessment of each portfolio, the Group assessed the contracts under the new five-step model under ASC 606 and determined there was no significant impact to the timing or amount of revenue recognition under the new guidance.

Under the Group’s previous accounting policy, deferred revenue comprised deferred upfront payments from the Group’s license and collaboration contracts. Under ASC 606, advance payments from customers preceding an entity’s performance are considered contract liabilities; therefore, advance payments from customers from the Group’s Commercial Platform have been reclassified from other payables, accruals and advance receipts to deferred revenue. Expected rebates for sales of goods remain in other payables, accruals and advance receipts.

The following tables summarize the impact of adopting ASC 606 on the Group’s consolidated financial statements as at and for the year ended December 31, 2018, as compared to the amounts as if applying ASC 605:

Accounting policy—ASC 606

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Group from a customer, are also excluded from revenue. The Group recognizes revenue when it satisfies a performance obligation by transferring control over a good, service or license to a customer.

Nature of goods and services

The following is a description of principal activities, separated by reportable segments, from which the Company generates its revenue:

(i)    Innovation Platform

The Innovation Platform reportable segment principally generates revenue from license and collaboration contracts. The license and collaboration contracts generally contain multiple performance obligations including (1) the license to the commercialization rights of a drug compound and (2) the research and development services for each specified treatment indication, which are accounted for separately if they are distinct, i.e. if a product or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer.

The transaction price generally includes fixed and variable consideration in the form of upfront payment, research and development cost reimbursements, contingent milestone payments and sales-based royalties. Contingent milestone payments are not included in the transaction price until it becomes probable that a significant reversal of revenue will not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation is based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. The Group estimates the standalone selling prices based on the income approach. Control of the license to the drug compounds transfers at the inception date of the collaboration agreements and consequently, amounts allocated to this performance obligation are generally recognized at a point in time. Conversely, research and development services for each specified indication are performed over time and amounts allocated to these performance obligations are generally recognized over time using cost inputs as a measure of progress. The Group has determined that research and development expenses provide an appropriate depiction of measure of progress for the research and development services. Changes to estimated cost inputs may result in a cumulative catch-up adjustment. Royalty revenues are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception, and are included in Commercial Platform revenues.

Deferred revenue is recognized if allocated consideration is received in advance of the Group rendering research and development services. Accounts receivable is recognized based on the terms of the contract and when the Group has an unconditional right to bill the customer, which is generally when research and development services are rendered.

(ii)    Commercial Platform

The Commercial Platform reportable segment principally generates revenue from (1) sales of goods, which are the manufacture or purchase and distribution of products including a prescription drug product developed by the Innovation Platform and other consumer health products, (2) royalty revenues from license and collaboration contracts and (3) sales of services, which are the provision of sales, distribution and marketing services to pharmaceutical manufacturers. The Group evaluates whether it is the principal or agent for these contracts, which include prescription drug products and consumer health products. Where the Group obtains control of the goods for distribution, it is the principal (i.e. recognizes sales of goods on a gross basis). Where the Group does not obtain control of the goods for distribution, it is the agent (i.e. recognizes provision of services on a net basis). Control is primarily evidenced by taking physical possession and inventory risk of the goods.

Revenue from sales of goods is recognized when the customer takes possession of the goods. This usually occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, the Group recognizes revenue from provision of services based on amounts that can be invoiced to the customer.

Deferred revenue is recognized if consideration is received in advance of transferring control of the goods or rendering of services. Accounts receivable is recognized if the Group has an unconditional right to bill the customer, which is generally when the customer takes possession of the goods or services are rendered. Payment terms differ by subsidiary and customer, but generally range from 45 to 180 days from the invoice date.

Prior accounting policy—ASC 605

Sales

Revenue from sales of goods in the Commercial Platform segment are recognized when goods are delivered and title passes to the customer and there are no further obligations to the customer. Recognition of revenue also requires reasonable assurance of collection of sales proceeds and completion of all performance obligations. Sales discounts are issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from sales of services in the Commercial Platform segment are recognized based on amounts that can be invoiced to the customer. The amount that can be invoiced corresponds directly with the value to the customer for performance completed to date.

Revenues from research and development projects

The Group recognizes revenue for the performance of services when each of the following four criteria are met: (i) persuasive evidence of an arrangement exists; (ii) services are rendered; (iii) the sales price is fixed or determinable; and (iv) collectability is reasonably assured.

The Group follows ASC 605-25, Revenue Recognition—Multiple-Element Arrangements and ASC 808, Collaborative Arrangements, if applicable, to determine the recognition of revenue under the Group’s license and collaborative research, development and commercialization agreements. The terms of these agreements generally contain multiple elements, or deliverables, which may include (i) licenses to the Group’s intellectual property, (ii) materials and technology, (iii) clinical supply, and/or (iv) participation in joint research or joint steering committees. The payments the Group may receive under these arrangements typically include one or more of the following: non-refundable, upfront license fees; funding of research and/or development efforts; amounts due upon the achievement of specified milestones; and/or royalties on future product sales.

ASC 605-25 provides guidance relating to the separability of deliverables included in an arrangement into different units of accounting and the allocation of arrangement consideration to the units of accounting. The evaluation of multiple-element arrangements requires management to make judgments about (i) the identification of deliverables, (ii) whether such deliverables are separable from the other aspects of the contractual relationship, (iii) the estimated selling price of each deliverable, and (iv) the expected period of performance for each deliverable.

To determine the units of accounting under a multiple-element arrangement, management evaluates certain separation criteria, including whether the deliverables have stand-alone value, based on the relevant facts and circumstances for each arrangement. Management then estimates the selling price for each unit of accounting and allocates the arrangement consideration to each unit utilizing the relative selling price method. The Group determines the estimated selling price for deliverables within each agreement using vendor-specific objective evidence (“VSOE”) of selling price, if available, or third party evidence of selling price if VSOE is not available, or the Group’s best estimate of selling price, if neither VSOE nor third party evidence is available. Determining the best estimate of selling price for a deliverable requires significant judgment. The Group typically uses its best estimate of a selling price to estimate the selling price for licenses to development work, since it often does not have VSOE or third party evidence of selling price for these deliverables. In those circumstances where the Group applies its best estimate of selling price to determine the estimated selling price of a license to development work, it considers market conditions as well as entity-specific factors, including those factors contemplated in negotiating the agreements as well as internally developed estimates that include assumptions related to the market opportunity, estimated development costs, probability of success and the time needed to commercialize a product candidate pursuant to the license. In validating its best estimate of selling price, the Group evaluates whether changes in the key assumptions used to determine its best estimate of selling price will have a significant effect on the allocation of arrangement consideration between deliverables. The Group recognizes consideration allocated to an individual element when all other revenue recognition criteria are met for that element.

The allocated consideration for each unit of accounting is recognized over the related obligation period in accordance with the applicable revenue recognition criteria.

If there are deliverables in an arrangement that are not separable from other aspects of the contractual relationship, they are treated as a combined unit of accounting, with the allocated revenue for the combined unit recognized in a manner consistent with the revenue recognition applicable to the final deliverable in the combined unit. Payments received prior to satisfying the relevant revenue recognition criteria are recorded as unearned revenue in the accompanying balance sheets and recognized as revenue when the related revenue recognition criteria are met.

The Group typically receives non-refundable, upfront payments when licensing the Group’s intellectual property, which often occurs in conjunction with a research and development agreement. If management believes that the license to the Group’s intellectual property has stand-alone value, the Group generally recognizes revenue attributed to the license upon delivery provided that there are no future performance requirements for use of the license. When management believes that the license to the Group’s intellectual property does not have stand-alone value, the Group will recognize revenue attributed to the license ratably over the contractual or estimated performance period. For payments payable on achievement of milestones that do not meet all of the conditions to be considered substantive, the Group recognizes a portion of the payment as revenue when the specific milestone is achieved, and the contingency is removed. Other contingent event-based payments for which payment is either contingent solely upon the passage of time or the result of a collaborator’s performance are recognized when earned. The Group’s collaboration and license agreements generally include contingent milestone payments related to specified pre-clinical research and development milestones, clinical development milestones, regulatory milestones and sales-based milestones. Pre-clinical research and development milestones are typically payable upon the selection of a compound candidate for the next stage of research and development. Clinical development milestones are typically payable when a product candidate initiates or advances in clinical trial phases or achieves defined clinical events such as proof-of-concept. Regulatory milestones are typically payable upon submission for marketing approval with regulatory authorities or upon receipt of actual marketing approvals for a compound, approvals for additional indications, or upon the first commercial sale. Sales-based milestones are typically payable when annual sales reach specified levels.

At the inception of each arrangement that includes milestone payments, the Group evaluates whether each milestone is substantive and at risk to both parties on the basis of the contingent nature of the milestone. This evaluation includes an assessment of whether (a) the consideration is commensurate with either (i) the entity’s performance to achieve the milestone or (ii) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone; (b) the consideration relates solely to past performance; and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Group evaluates factors such as the scientific, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required to achieve the respective milestone and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment.

Research and Development Expenses

Research and development expenses consist primarily of salaries and benefits, share-based compensation, materials and supplies, contracted research, consulting arrangements and other expenses incurred to sustain the Group’s research and development programs. Research and development costs are expensed as incurred.

Government Incentives

Incentives from governments are recognized at their fair values. Government incentives that are received in advance are deferred and recognized in the consolidated statements of operations over the period necessary to match them with the costs that they are intended to compensate. Government incentives in relation to the achievement of stages of research and development projects are recognized in the consolidated statements of operations when amounts have been received and all attached conditions have been met. Non-refundable incentives received without any further obligations or conditions attached are recognized immediately in the consolidated statements of operations.

Leases

Summary of impact of applying ASC 842

The Group applied ASC 842 to its various leases at the date of initial application of January 1, 2019. As a result, the Group has changed its accounting policy for leases as detailed below. The core principle of ASC 842 is that a lessee should recognize the assets and liabilities that arise from leases. Therefore, the Group recognizes in the consolidated balance sheets liabilities to make lease payments (the lease liabilities) and right-of-use assets representing its right to use the underlying assets for their lease terms. The Group applied ASC 842 using the optional transition method by recognizing the cumulative effect as an adjustment to opening accumulated losses as at January 1, 2019. The comparative information prior to January 1, 2019 has not been adjusted and continues to be reported under ASC 840, Leases (“ASC 840”).

The Group assessed lease agreements as at January 1, 2019 under ASC 842, except for short-term leases. The Group elected the short-term lease exception for leases with a term of 12 months or less and recognizes lease expenses for such leases on a straight-line basis over the lease term and does not recognize right-of-use assets or lease liabilities accordingly. As a result of this assessment, the Group recorded an aggregate US$0.7 million in additional lease expenses as a cumulative adjustment to opening accumulated losses upon adoption. Additionally, the Group recognized right-of-use assets and lease liabilities of US$5.7 million and US$6.4 million respectively as at January 1, 2019.

The lease liabilities were measured at the present value of the remaining lease payments, discounted using the lessees’ incremental borrowing rate as at January 1, 2019. The Group’s weighted average incremental borrowing rate applied on January 1, 2019 was 3.97% per annum.

A reconciliation of the Group’s reported operating lease commitments as at December 31, 2018 and the Group’s lease liabilities recognized upon adoption of ASC 842 as at January 1, 2019 is as follows:

	(in US$’000)
Operating lease commitments as at December 31, 2018 (note (a))	8,835
Less: Leases not commenced as at January 1, 2019	(3,676)
Less: Short‑term leases	(5)
Add: Adjustment as a result of the treatment for a termination option (note (b))	1,409
Less: Discount under the lessees’ incremental borrowing rate as at January 1, 2019	(206)
Lease liabilities recognized as at January 1, 2019	6,357

Notes:

(a) Future aggregate minimum payments under non-cancellable operating leases under ASC 840 were as follows:

	December 31,
	2018
	(in US$’000)
Not later than 1 year	3,026
Between 1 to 2 years	2,735
Between 2 to 3 years	1,056
Between 3 to 4 years	882
Between 4 to 5 years	810
Later than 5 years	326
Total minimum lease payments	8,835

(b) The Group leases its corporate offices in Hong Kong through a support service agreement with an indirect subsidiary of CK Hutchison Holdings Limited (“CK Hutchison”), which is the Company’s indirect major shareholder. The support service agreement may be terminated by giving 3-month advance notice; therefore, there was no lease commitment beyond the 3-month advance notice period as at December 31, 2018. This termination option is not considered probable of exercise for the purposes of applying ASC 842.

The Group recognized right-of-use assets as at January 1, 2019 measured at their carrying amounts as if ASC 842 had been applied since their commencement dates, but discounted using the lessees’ incremental borrowing rate as at January 1, 2019.

Recognized right-of-use assets upon adoption were as follows:

	(in US$’000)
Offices	4,877
Factories	383
Others	487
	5,747

There were no adjustments to net cash generated from/(used in) operating activities, investing activities or financing activities in the consolidated statement of cash flows.

In applying ASC 842 for the first time, the Group has used the following practical expedients permitted by the standard: (i) no reassessment of whether any expired or existing contracts are or contain leases; (ii) no reassessment of the lease classification for any expired or existing leases; (iii) the exclusion of initial direct costs for the measurement of the right-of-use assets at the date of initial application; and (iv) the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

Updated accounting policy—ASC 842

In an operating lease, a lessee obtains control of only the use of the underlying asset, but not the underlying asset itself. An operating lease is recognized as a right-of-use asset with a corresponding liability at the date which the leased asset is available for use by the Group. The Group recognizes an obligation to make lease payments equal to the present value of the lease payments over the lease term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.

Lease liabilities include the net present value of the following lease payments: (i) fixed payments; (ii) variable lease payments; and (iii) payments of penalties for terminating the lease if the lease term reflects the lessee exercising that option, if any. Lease liabilities exclude the following payments that are generally accounted for separately: (i) non-lease components, such as maintenance and security service fees and value added tax, and (ii) any payments that a lessee makes before the lease commencement date. The lease payments are discounted using the interest rate implicit in the lease or if that rate cannot be determined, the lessee’s incremental borrowing rate being the rate that the lessee would have to pay to borrow the funds in its currency and jurisdiction necessary to obtain an asset of similar value, economic environment and terms and conditions.

An asset representing the right to use the underlying asset during the lease term is recognized that consists of the initial measurement of the operating lease liability, any lease payments made to the lessor at or before the commencement date less any lease incentives received, any initial direct cost incurred by the Group and any restoration costs.

After commencement of the operating lease, the Group recognizes lease expenses on a straight-line basis over the lease term. The right-of-use asset is subsequently measured at cost less accumulated amortization and any impairment provision. The amortization of the right-of-use asset represents the difference between the straight-line lease expense and the accretion of interest on the lease liability each period. The interest amount is used to accrete the lease liability and to amortize the right-of-use asset. There is no amount recorded as interest expense.

Payments associated with short-term leases are recognized as lease expenses on a straight-line basis over the period of the leases.

Subleases of right-of-use assets are accounted for similar to other leases. As an intermediate lessor, the Group separately accounts for the head-lease and sublease unless it is relieved of its primary obligation under the head-lease. Sublease income is recorded on a gross basis separate from the head-lease expenses. If the total remaining lease cost on the head-lease is more than the anticipated sublease income for the lease term, this is an indicator that the carrying amount of the right-of-use asset associated with the head-lease may not be recoverable, and the right-of-use asset will be assessed for impairment.

Prior accounting policy - ASC 840

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the period of the leases.

Total operating lease rentals for factories and offices for the years ended December 31, 2018 and  2017 amounted to US$3,759,000 and US$2,285,000 respectively. Sublease rentals for the years ended December 31, 2018 and 2017 amounted to US$254,000 and US$274,000 respectively.

Interest Income

Interest generated from cash and cash equivalents and short-term investments is recorded over the period earned. It is measured based on the actual amount of interest the Group earns.

Income Taxes

The Group accounts for income taxes under the liability method. Under the liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the income tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of the net deferred income tax asset will not be realized.

The Group accounts for an uncertain tax position in the consolidated financial statements only if it is more likely than not that the position is sustainable based on its technical merits and consideration of the relevant tax authority’s widely understood administrative practices and precedents. If the recognition threshold is met, the Group records the largest amount of  tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement.

The Group recognizes interest and penalties for income taxes, if any, under income tax payable on its consolidated balance sheets and under other expenses in its consolidated statements of operations.

Comprehensive Loss

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions, and other events and circumstances from non-owner sources, and currently consists of net loss and foreign currency translation (loss)/gain related to the Company’s subsidiaries.

Losses per Share

Basic losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Weighted average number of outstanding ordinary shares in issue excludes treasury shares.

Diluted losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include ordinary shares and treasury shares issuable upon the exercise or settlement of share-based awards issued by the Company using the treasury stock method. The computation of diluted losses per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect.

Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief executive officer who is the Group’s chief operating decision maker. The chief operating decision maker reviews the Group’s internal reporting in order to assess performance and allocate resources and determined that the Group’s reportable segments are as disclosed in Note 25.

Profit Appropriation and Statutory Reserves

The Group’s subsidiaries and equity investees established in the PRC are required to make appropriations to certain non-distributable reserve funds.

In accordance with the relevant laws and regulations established in the PRC, the Company’s subsidiaries registered as wholly-owned foreign enterprise have to make appropriations from their after-tax profits (as determined under generally accepted accounting principles in the PRC (“PRC GAAP”)) to reserve funds including general reserve fund, enterprise expansion fund and staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the company. Appropriations to the enterprise expansion fund and staff bonus and welfare fund are made at the respective company’s discretion. For the Group’s equity investees, the amount of appropriations to these funds are made at the discretion of their respective boards.

In addition, Chinese domestic companies must make appropriations from their after-tax profits as determined under PRC GAAP to non-distributable reserve funds including statutory surplus fund and discretionary surplus fund. The appropriation to the statutory surplus fund must be 10% of the after-tax profits as determined under PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the company. Appropriation to the discretionary surplus fund is made at the respective company’s discretion.

The use of the general reserve fund, enterprise expansion fund, statutory surplus fund and discretionary surplus fund is restricted to the offsetting of losses or increases to the registered capital of the respective company. The staff bonus and welfare fund is a liability in nature and is restricted to fund payments of special bonus to employees and for the collective welfare of employees. All these reserves are not permitted to be transferred to the company as cash dividends, loans or advances, nor can they be distributed except under liquidation.

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including accounts receivable and other receivables. The Group currently does not expect ASU 2016-13 to have a material impact to the Group’s consolidated financial statements.

Amendments that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Group’s consolidated financial statements upon adoption.

Notes:

(a) Sales of goods are recognized at a point-in-time and sales of services are recognized over time. The implementation of the two-invoice system in China over the periods presented resulted in a shift from a gross sales of goods revenue model to a net fee-for-service revenue model in the Group’s Commercial Platform, as the Group does not obtain control of the goods for distribution for relevant transactions and is thus considered an agent under ASC 606. Refer to Note 3.

(b) Goods— Innovative Medicines and royalties relate to revenue from a prescription drug developed by the Innovation Platform and launched into the market. It was represented under the Commercial Platform due to its transition to the commercial stage for segment reporting. Refer to Note 25.

(c) Under ASC 606, relates to the proportionate amount of milestone payment allocated to the license to the commercialization rights of a drug compound transferred at the inception date of the relevant license and collaboration contract. During the year ended December 31, 2018, the Group received a milestone of US$13.5 million, of which US$12.1 million was allocated to licenses and US$1.4 million was allocated to services.

(d) Under ASC 605, relates to milestone payments recognized under the milestone method.

Innovation Platform

Innovation Platform revenue is mainly from license and collaboration agreements as follows:

License and collaboration agreement with Eli Lilly

On October 8, 2013, the Group entered into a licensing, co-development and commercialization agreement in China with Eli Lilly and Company (“Lilly”) relating to fruquintinib (“Lilly Agreement”), a targeted oncology therapy for the treatment of various types of solid tumors. Under the terms of the Lilly Agreement, the Group is entitled to receive a series of payments up to US$86.5 million, including upfront payments and development and regulatory approval milestones. Fruquintinib was successfully commercialized in China in November 2018, and the Group receives tiered royalties in the range of 15% to 20% on all sales in China. Development costs after the first development milestone are shared between the Group and Lilly.

In December 2018, the Group entered into various amendments to the Lilly Agreement (the “2018 Amendment”). Under the terms of the 2018 Amendment, the Group is entitled to determine and conduct future life cycle indications (“LCI”) development of fruquintinib in China beyond the three initial indications specified in the Lilly Agreement and will be responsible for all associated development costs. In return, the Group will receive additional regulatory approval milestones of US$20 million for each LCI approved, for up to three LCI or US$60 million in aggregate, and will increase tiered royalties to a range of 15% to 29% on all fruquintinib sales in China upon the commercial launch of the first LCI.

The 2018 Amendment provides the Group rights to promote fruquintinib in provinces that represent 30% of the sales of fruquintinib in China upon the occurrence of certain commercial milestones by Lilly. Such provinces will expand to 40% of the sales of fruquintinib in China subject to additional criteria being met. In return, Lilly will pay the Group service fees for such promotion and marketing services performed. Additionally, Lilly has provided consent, and freedom to operate, for the Group to enter into joint development collaborations with certain third-party pharmaceutical companies to explore combination treatments of fruquintinib and various immunotherapy agents.

Upfront and cumulative milestone payments according to the Lilly Agreement received up to December 31, 2019 are summarized as follows:

	(in US$’000)
Upfront payment	6,500
Development milestone payments achieved	40,000

In addition, the Group signed an option agreement which grants Lilly an exclusive option to expand the fruquintinib rights beyond Hong Kong and China. The option agreement further sets out certain milestone payments and royalty rates that apply in the event the option is exercised on a global basis. The option was determined at the inception of the contract to have minimal value, and in January 2019, Lilly elected not to exercise the option.

The Group adopted ASC 606 on January 1, 2018 and reassessed the Lilly Agreement under the new standard, which resulted in US$0.1 million recognition of previously deferred revenue as a cumulative adjustment to opening accumulated losses as at January 1, 2018, summarized as follows (in US$ millions).

	ASC 605		ASC 606
	December 31,	Opening	January 1,
	2017	Adjustments	2018
Cumulative amounts recognized to accumulated losses from:
Upfront payment (note (a))	5.7	0.5	6.2
Milestone payments (note (b))	23.7	(0.4)	23.3
	29.4	0.1	29.5

Notes:

(a) Upfront payment amounts deferred under ASC 605, but was allocated to the license to fruquintinib transferred at inception under ASC 606, resulting in additional revenue recognition on adoption.

(b) Milestone payments had been fully recognized under ASC 605’s milestone method, but was allocated to the portion of research and development services that had not been performed under ASC 606, resulting in deferral of revenue on adoption.

Under ASC 606, the Group identified the following performance obligations under the Lilly Agreement: (1) the license for the commercialization rights to fruquintinib and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to fruquintinib and the research and development services were 90% and 10% respectively. Control of the license to fruquintinib transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using the prior and estimated future development costs for fruquintinib as a measure of progress. Royalties are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

The Group identified the following performance obligations under the 2018 Amendment: (1) the research and development services for the LCI and (2) the promotion and marketing services. As at December 31, 2019, no regulatory approval milestones were achieved and no promotion and marketing services had commenced.

Revenue recognized under the Lilly Agreement by transaction price type is as follows:

	ASC 606		ASC 605
	Year Ended December 31,
	2019	2018	2017
	(in US$’000)
Research and development cost reimbursements	3,910	9,309	12,145

Royalties	2,653	261	—
Goods – Innovative Medicines	8,113	3,324	—
	14,771	26,865	18,228

Note: During the years ended December 31, 2017 and 2018, the Group achieved milestones in relation to the acceptance and approval respectively, of a new drug application by the National Medical Products Administration of China for fruquintinib as a treatment of patients with advanced colorectal cancer.  During the year ended December 31, 2019, no milestones were achieved.

License and collaboration agreement with AstraZeneca

On December 21, 2011 (as amended on August 1, 2016), the Group and AstraZeneca AB (publ) (“AZ”) entered into a global licensing, co-development, and commercialization agreement for savolitinib (“AZ Agreement”), a novel targeted therapy and a highly selective inhibitor of the c-Met receptor tyrosine kinase for the treatment of cancer. Under the terms of the AZ Agreement, the Group is entitled to receive a series of payments up to US$140 million, including upfront payments and development and first-sale milestones. Additionally, the AZ Agreement contains possible significant future commercial sale milestones. Should savolitinib be successfully commercialized outside China, the Group would receive tiered royalties from 9% to 13% on all sales outside of China. Subject to approval of savolitinib in papillary renal cell carcinoma, the Group would receive increased tiered royalties from 14% to 18% on all sales outside of China, and after total aggregate sales of savolitinib have reached US$5 billion, this royalty will step down over a two-year period to an ongoing tiered royalty rate from 10.5% to 14.5%. Should savolitinib be successfully commercialized in China, the Group would receive fixed royalties of 30% based on all sales in China. Development costs for savolitinib in China will be shared between the Group and AZ, with the Group continuing to lead the development in China. AZ will lead and pay for the development of savolitinib for the rest of the world.

Upfront and cumulative milestone payments according to the AZ Agreement received up to December 31, 2019 are summarized as follows:

	(in US$’000)
Upfront payment	20,000
Development milestone payments achieved	25,000

The Group adopted ASC 606 on January 1, 2018 and reassessed the AZ Agreement under the new standard, which resulted in US$1.2 million deferral of previously recognized revenue as a cumulative adjustment to opening accumulated losses as at January 1, 2018, summarized as follows (in US$ millions).

	ASC 605		ASC 606
	December 31,	Opening	January 1,
	2017	Adjustments	2018
Cumulative amounts recognized to accumulated losses from:
Upfront payment (note (a))	19.6	(0.3)	19.3
Milestone payments (note (b))	24.9	(0.9)	24.0
	44.5	(1.2)	43.3

Notes:

(a) Upfront payment amounts allocated to research and development services recognized under ASC 606 differed from ASC 605 due to a different basis in measuring progress on adoption, resulting in deferral of revenue.

(b) Milestone payments had been fully recognized under ASC 605’s milestone method, but was allocated to the portion of research and development services that had not been performed under ASC 606, resulting in deferral of revenue on adoption.

Under ASC 606, the Group identified the following performance obligations under the AZ Agreement: (1) the license for the commercialization rights to savolitinib and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to savolitinib and the research and development services were 95% and 5% respectively. Control of the license to savolitinib transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using the prior and estimated future development costs for savolitinib as a measure of progress.

Revenue recognized under the AZ Agreement by transaction price type is as follows:

	ASC 606		ASC 605
	Year Ended December 31,
	2019	2018	2017
	(in US$’000)

Recognition and amortization of the milestone payments (note)	342	387	4,963
	11,527	6,536	8,087

Note: During the year ended December 31, 2017, the Group achieved a milestone in relation to the Phase III initiation for the secondary indication papillary renal cell carcinoma. During the years ended December 31, 2018 and 2019, no milestones were achieved.

25. Segment Reporting

The Group determines its operating segments from both business and geographic perspectives as follows:

(i) Innovation Platform (Drug R&D): focuses on discovering and developing for commercialization targeted therapies and immunotherapies for the treatment of cancer and immunological diseases; and

(ii) Commercial Platform: comprises of the manufacture, marketing and distribution of prescription drugs and over-the-counter pharmaceuticals in the PRC as well as consumer health products through Hong Kong. The Commercial Platform is further segregated into two core business areas:

(a) Prescription Drugs: comprises the development, manufacture, distribution, marketing and sale of prescription drugs; and

(b) Consumer Health: comprises the development, manufacture, distribution, marketing and sale of over-the-counter pharmaceuticals and consumer health products.

Innovation Platform and Prescription Drugs businesses under the Commercial Platform are primarily located in the PRC. The locations for Consumer Health business under the Commercial Platform are further segregated into the PRC and Hong Kong.

The performance of the reportable segments is assessed based on segment operating (loss)/profit.

In the second half of 2019, the Group began including the results from manufacturing and commercializing a prescription drug developed by the Innovation Platform and launched into the market under Prescription Drugs in the Commercial Platform. It has been included in the Commercial Platform due to its transition to the commercial stage and because commercial resources for innovative medicines are built under the Commercial Platform. The segment information below as at and for the year ended December 31, 2018 has been revised so that all segment disclosures are comparable. There was no revision necessary as at and for the year ended December 31, 2017.

Notes:

(a) The summarized statement of operations for NSPL for the year ended December 31, 2019 is presented up to December 9, 2019  when NSPL became a subsidiary of the Group. NSPL did not have any operating activities for the year ended December 31, 2019 and primarily incurred research and development expenses and an impairment provision during the years ended December 31, 2018 and 2017.

(b) On November 19, 2018, NSPL’s Board reviewed the progress of its drug candidates. After due consideration of the timeline and further investments required to complete NSPL’s clinical trials and reach the commercialization stage, it decided to explore alternative strategic options to maximize the economic returns from the drug candidates. NSPL performed an annual impairment assessment of the recoverability of the related US$30 million intangible asset by comparing its carrying amount to the higher of the asset’s value-in-use or its fair value less costs to sell. There was no certainty of an available market or that a suitable buyer or partner can be readily identified and accordingly, NSPL recorded a full impairment provision for the year ended December 31, 2018. The Company’s attributable portion was US$15 million.

(c) The main entities within the HBYS and SHPL  groups have been granted the High and New Technology Enterprise (“HNTE”) status. Accordingly, the entities were eligible to use a preferential income tax rate of 15% for the years ended December 31, 2019, 2018 and 2017.

For the years ended December 31, 2019, 2018 and 2017, other immaterial equity investees had net income of approximately US$95,000, US$236,000 and US$117,000 respectively.
