All statements, other than statements of historical facts, included in this annual report that address activities, events or developments which we expect or anticipate will or may occur in the future are hereby identified as forward-looking statements for the purpose of the safe harbor provided by Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. The words such as “believe,” “intend,” “expect,” “anticipate,” “project,” “estimate,” “predict,” “plan” and similar expressions are also intended to identify forward-looking statements. These forward-looking statements address, among others, such issues as:

• amount and nature of future development;

• future prices of and demand for our products;

• future earnings and cash flow;

• capital expansion programs;

• fluctuations in crude oil and natural gas prices;

• fluctuations in prices of our products;

• failures or delays in achieving production from development projects;

• potential acquisitions and other business opportunities;

• continued availability of capital and financing;

• general economic, market and business conditions, including volatility in interest rates, changes in foreign exchange rates and volatility in commodity markets; and

• other risks and factors beyond our control.

Consequently, all of the forward-looking statements made in this annual report are qualified by these cautionary statements and readers are cautioned not to place undue reliance on these forward-looking statements. These forward-looking statements should be considered in light of the various important factors set forth above and elsewhere in this annual report, including the risks set forth in “Item 3. Key Information – Risk Factors.”. In addition, we cannot assure you that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected effect on us or our business or operations.

D. Risk Factors.

An investment in our ADSs involves significant risks. The risks and uncertainties described below are not the only ones we face. You should consider carefully all of the information in this annual report, including the risks and uncertainties described below and our consolidated financial statements and related notes, before making an investment in our ADSs. Any of the following risks could have a material adverse effect on our business, financial condition and results of operations. In any such case, the market price of our ADSs could decline, and you may lose all or part of your investment.

Our operations may be adversely affected by the cyclical nature of the petroleum and petrochemical markets and by the volatility of prices of crude oil and petrochemical products.

Most of our revenues are attributable to the sale of refined oil and petrochemical products, which have historically been cyclical and sensitive to the availability and price of raw materials and general economic conditions. Markets for many of our products are sensitive to changes in industry capacity and output levels, changes in regional and global economic conditions, the price and availability of substitute products and changes in consumer demand, which from time to time have had a significant impact on our product prices in the regional and global markets. Due to the decrease in tariff charges, the removal of other restrictions on importation and the Chinese government’s gradual relaxation of its control of the allocation of products and pricing, many of our products have become increasingly vulnerable to the cyclical nature of regional and global petroleum and petrochemical markets, which may adversely affect our operations.

We consume large amounts of crude oil to manufacture our products of which more than 95% is typically imported. In 2017, crude oil costs accounted for RMB32.90 billion, or 45.45% of our annual cost of sales. As a result, changes in crude oil prices can affect our profitability. In recent years, due to various reasons, the price of crude oil has fluctuated significantly. We cannot rule out the possibility of the occurrence of certain global emergencies which might disrupt our crude oil supply. We expect that the volatility and uncertainty of the prices of crude oil and petrochemical products will continue, and that increasing crude oil prices and declines in prices of petrochemical products may adversely affect our business and results of operations and financial condition.

3

Some of our major products are subject to government price controls, and we are not able to pass on all cost increases from rising crude oil prices through higher product prices.

We consume large amounts of crude oil to manufacture our products of which more than 95% is typically imported. We attempt to mitigate the effect of increased costs due to rising crude oil prices. However, our ability to pass on these increased costs to our customers is dependent on market conditions and government regulations. Given that the increase of the sales prices of our products may lag behind the increase of crude oil costs, we may fail to completely cover the increased costs by increasing our sales prices, particularly where government regulations restrict the prices of certain of our fuel products. In particular, gasoline, diesel and jet fuel, and liquefied petroleum gas are subject to government price controls at present. In 2015, 2016 and 2017 approximately 40.81%, 36.40% and 40.90% of our net sales were from such products subject to price controls. Although the current price-setting mechanism for refined petroleum products in China allows the Chinese government to adjust price in the PRC market when the average international crude oil price fluctuates beyond certain levels within a certain time period (see Item 4. Information on the Company – B. Business Overview – Product Pricing), the Chinese government still retains discretion as to whether or when to adjust the prices of the refined oil products. The Chinese government generally exercises certain price control over refined oil products once international crude oil prices experience a sustained rise or become significantly volatile. For instance, some of our fuel products are required to be sold to designated distributors (such as the subsidiaries of Sinopec Corp.). Because we cannot freely sell our fuel products to take advantage of opportunities for higher prices, we may not be able to fully cover increases in crude oil prices by increasing the sale prices of our products, which has had and will possibly continue to have a material adverse effect on our financial condition, results of operations and cash flows.

Our development and operation plans have significant capital expenditure and financing requirements, which are subject to a number of risks and uncertainties.

The petrochemical business is a capital intensive business. Our ability to maintain and increase our revenues, net income and cash flows depends upon continued capital spending. Our current business strategy contemplates capital expenditure for 2018 of approximately RMB1.2 billion (U.S.$184.4 million), which will be provided through financing activities and use of our own capital. Our actual capital expenditures may vary significantly from these planned amounts, subject to our ability to generate sufficient cash flows from operations, investments and other factors that may be beyond our control. In addition, there can be no assurance as to whether, or at what cost, our capital projects will be completed or the success of these projects if completed.

As of March 31, 2018, we had an aggregate outstanding indebtedness of approximately RMB1,065.2 million (U.S.$163.7 million). Most of our borrowings are with state-controlled banks in China and structured as short term debt obligations with payment due in one year or less. These banks have generally been willing to provide new short term loans while we pay off existing loans. Sinopec Corp., our controlling shareholder, did not provide any guarantee or credit support for our debt for the year ended December 31, 2017 and for the three months ended March 31, 2018.

Our ability to obtain external financing in the future and our ability to make timely repayments of our debt obligations are subject to a variety of uncertainties, including: our future results of operations, financial condition and cash flows; the condition of the economy in China and the condition of markets for our products; the cost of financing and the condition of financial markets; the issuance of relevant government approvals and other project risks associated with the development of infrastructure in China; and the continuing willingness of banks to provide new loans as we pay down existing debt.

While we anticipate that we will rely less on borrowings to finance capital expenditures and operations, our business, results of operations and financial condition could be adversely affected if we fail to obtain sufficient funding for our operations or development plans.

Our business operations may be adversely affected by present or future environmental regulations.

We are subject to extensive environmental protection laws and regulations in China. These laws and regulations permit:

• the imposition of pollution charge for the discharge of waste substances;

• the levy of payments and fines for damages for serious environmental offenses;

• the government to close down or suspend any facility which has caused or may cause environmental damages and require it to correct or stop operations causing environmental damages; and

• litigations and liabilities arising from pollutions and damages to the environment and public interests.

4

Our production operations produce substantial amounts of waste materials (i.e., waste water, waste gas and waste residue). In addition, our production and operations require environmental related permits that are subject to renewal, modification and revocation. We were subject to various administrative penalties for violations of the relevant PRC environmental laws and regulations in the past years. See Item 4. Information of the Company – B. Business Overview – Environmental Protection. We have established a system to treat waste materials to prevent and reduce pollution. The Chinese government (including the local governments), however, has moved, and may move further, toward the adoption of more regulations and more stringent environmental standards. Chinese national or local authorities may also apply more rigorous enforcement of such regulations which would require us to incur additional expenditures on environmental matters.

If the Chinese government changes current regulations that allow us to make payments in foreign currencies, we may be unable to obtain the foreign currency necessary for our business.

The Renminbi currently is not a freely convertible currency. We receive most of our revenue in Renminbi. A portion of our Renminbi revenue must be converted into other currencies to meet our foreign currency needs, which include, among other things:

• debt service costs on foreign currency-denominated debt;

• purchases of imported equipment;

• payment of any cash dividends declared in respect of the H shares and the ADSs; and

• import of crude oil and other materials.

Under existing foreign exchange regulations in China, we may undertake current account foreign exchange transactions, including the payment of dividends, without prior approval from the State Administration of Foreign Exchange (“SAFE”) by producing commercial documents evidencing the foreign exchange transactions, provided that they are processed through Chinese banks licensed to engage in foreign exchange transactions. Foreign exchange transactions under the capital account (international revenues and expenditures that increase or decrease debt or equity, including principal payments in respect of foreign currency-denominated obligations) continue to be subject to limitations and require the prior approval of the SAFE. These limitations could affect our ability to obtain foreign exchange through debt financing, or to make capital expenditures in foreign currency. The Chinese government has stated publicly that it intends to eventually make the Renminbi freely convertible in the future. However, we cannot predict whether the PRC government will continue its existing foreign exchange policy and when the PRC government will allow free conversion of Renminbi.

If the Chinese government restricts our ability to make payments in foreign currency, we may be unable to obtain the foreign currency necessary for our business. In that case, our business may be materially adversely affected, and we may default on our obligations.

Change of currency policy and fluctuation of Renminbi might adversely affect our business and operating results.

The exchange rate between the Renminbi and the U.S. Dollar or other foreign currencies might fluctuate and be affected by the change in China’s political and economic conditions and China’s foreign exchange policies. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the RMB to the U.S. dollar, and the RMB appreciated more than 20% against the U.S. dollar over the following three years. However, the People’s Bank of China, or the PBOC, regularly intervenes in the foreign exchange market to limit fluctuations in RMB exchange rates and achieve policy goals. During the period between July 2008 and June 2010, the exchange rate between the RMB and the U.S. dollar had been stable and traded within a narrow range. However, the RMB fluctuated significantly during that period against other freely traded currencies, in tandem with the U.S. dollar. Since June 2010, the RMB has started to slowly appreciate against the U.S. dollar, though there have been periods when the U.S. dollar has appreciated against the RMB. On August 11, 2015, the PBOC allowed the RMB to depreciate by approximately 2% against the U.S. dollar. During 2016, the RMB depreciated by over 6.83% against the U.S. dollar. During 2017, the RMB appreciated by over 6.16% against the U.S. dollar. It is difficult to predict how long such appreciation of RMB against the U.S. dollar may last and when and how the relationship between the RMB and the U.S. dollar may change again. There remains significant international pressure on the PRC government to adopt a flexible currency policy.

A portion of our cash and cash equivalents is denominated in foreign currencies (mainly the U.S. Dollar). As of December 31, 2017, our bank deposits denominated in foreign currencies were equivalent to RMB247.5 million. The appreciation in the value of Renminbi against foreign currencies (including the U.S. Dollar) may cause a decrease in the Renminbi value of our cash and cash equivalents that are denominated in foreign currencies. In addition, the appreciation of Renminbi may harm the exports of our downstream manufacturers, thus adversely affecting the market demand for our products.

Although most of our revenue is denominated in Renminbi, most of our purchase of crude oil and some equipment and repayments of certain borrowings are made in foreign currencies. Any depreciation of the Renminbi would increase our cost and adversely affect our capacity of making profits. In addition, any depreciation of the Renminbi could adversely affect the value of the dividends of our H shares and ADSs, which we declare in Renminbi and pay in foreign currencies.

We are controlled by Sinopec Corp., whose interests may not be aligned with yours.

As of March 31, 2018, Sinopec Corp. owned 50.44% of our shares. Accordingly, it has voting and management control over us, and its interests may be different from the interests of our other shareholders. Subject to our Articles of Association and applicable laws and regulations, Sinopec Corp. will be in a position to cause us to declare dividends, determine the outcome of corporate actions requiring shareholder approval or effect corporate transactions without the approval of the holders of the H shares and ADSs. Any such increase in our dividend payout would reduce funds available for reinvestment in our business and any such actions or transactions could adversely affect us or our minority shareholders. Sinopec Corp. may also experience changes in its own business strategy and policies. Although we are not currently aware of any specific changes, they could, in turn, lead Sinopec Corp. to change its policies or practices toward us in ways that we cannot predict, with corresponding unpredictable consequences for our business. Additionally, Sinopec Corp. may leverage its controlling shareholder position to influence our decisions with regard to the manufacturing and operation, allocation of financial resources and appointment and removal of senior management members, which could adversely affect us or our minority shareholders.

We have also engaged from time to time and will continue to engage in a variety of transactions with Sinopec Corp., Sinopec Group, the controlling company of Sinopec Corp., and their various subsidiaries or affiliates which provide a number of services to us, including the supply of raw materials, product distribution and sales agency, project design and installment service, petrochemical industry related insurance and financial services. We also sell oil and petrochemical products to Sinopec Corp. and its affiliates. Our transactions with these companies are governed by a Mutual Product Supply and Sales Services Framework Agreement with Sinopec Corp. and a Comprehensive Services Framework Agreement with Sinopec Group, the terms of which were negotiated on an arm’s length basis. See Item 7. Major Shareholders and Related Party Transactions – B. Related Party Transactions. Our business and results of operations could be adversely affected if Sinopec Corp. or Sinopec Group refuses to engage in such transactions or if it seeks to amend the contracts between the parties in a way adverse to us. In addition, Sinopec Corp. has interests in businesses which compete or are likely to compete, either directly or indirectly, with our businesses. Because Sinopec Corp. is our controlling shareholder and its interests may conflict with our own interests, Sinopec Corp. may take actions that favor itself over our interests.

Our operations are exposed to risks relating to operating hazards and production safety and we have limited insurance coverage for resulting losses.

Our operations involve the handling and storage of explosives and other hazardous articles. In addition, our operations involve the use of heavy machinery, which involves inherent risks that cannot be entirely eliminated through our preventive efforts. As a result, we may encounter fires, explosions and other unexpected incidents during our operations, which may cause personal injuries or death, property damage, environmental damage, interruption of operations and reputational damages to us. Each of such incidents could have a material adverse impact on our financial condition and results of operations.

We maintain a package of insurance coverage plan through Sinopec Group on our property, facilities and inventory. In addition, we maintain insurance policies for such assets as the engineering construction projects and products in transit with third-party commercial insurance companies. We carry a third party liability insurance with a coverage capped at RMB50 million in 2018 to cover claims, subject to deductibles, in respect of personal injury, property or environmental damage arising from accidents on our property or relating to our operations other than on our transportation vehicles. Our insurance coverage may not be sufficient to cover all the financial losses caused by operating hazards. Resulting losses required to be compensated or otherwise paid for by us due to such operating hazards that are not fully insured against may have a material adverse effect on our financial condition and results of operations.

Our business may be limited or adversely affected by government regulations.

The Chinese central and local governments continue to exercise a certain degree of control over the petrochemical industry in China by, among other things:

• mandating distribution channels for our fuel products;

• setting the allocations and pricing of certain resources, products and services;

• assessing taxes and fees payable;

• setting import and export quotas and procedures; and

• setting safety, environmental and quality standards.

As a result, we may face significant constraints on our flexibility and ability to expand our business operations or to maximize our profitability. In the past, we have benefited from favorable regulatory policies that have, for example, reduced the competition we face from illegal imports of petroleum products. Existing policies that favor our industry may change in the future and our business could be adversely affected by any such changes.

Our development plans may require regulatory approval.

We are currently engaged in a number of construction and expansion projects. Most of our projects are subject to governmental review and approval. The timing and cost of completion of these projects will depend on numerous factors, including approvals from relevant government authorities and general economic conditions in China.

6

While in general we attempt to obtain governmental approval as far in advance as practicable, we are unable to predict the timing and outcome of these governmental reviews and approvals. If any of our important projects required for our future growth are not approved, or not approved on a timely basis, our results of operations and financial condition could be adversely affected.

We could face increasing competition in China.

Our principal market, Eastern China, which is comprised of Shanghai, Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi and Fujian, has enjoyed stronger economic growth and a higher demand for petrochemical products than other regions of China. As a result, we believe that our competitors will try to expand their sales and build up their distribution networks in our principal market. We believe this will have an adverse impact on the production and sale of our major products. Moreover, Chinese private enterprises have gradually overcome technological and funding barriers to extend their business from the downstream processing sector to the upstream petrochemical field. These enterprises have advantages in many areas such as flexibility in operation costs, preferential policy treatments and regional presence, and may use these advantages to compete with us in our target market.

We face increasing foreign competition in our lines of business.

China joined the WTO on December 11, 2001 and had committed to eliminate some tariff and non-tariff barriers to foreign competition in the domestic petrochemical industry that benefited us in the past. In particular, China:

• has reduced tariffs on imported petrochemicals products that compete with ours;

• increased levels of permitted foreign investment in the domestic petrochemicals industry, allowing foreign investors to own 100% of a domestic petrochemicals company from December 11, 2004;

• has gradually relaxed restrictions on the import of crude oil by non-state-owned companies;

• has granted foreign-owned companies the right to import petrochemical products; and

• has permitted foreign-owned companies to distribute and market fuel products in both retail and wholesale markets in China.

As a result of these measures, we face increasing competition from foreign companies and imports. In addition, competition for our products has increased, as many overseas companies have switched their focus to sales in China. Furthermore, tariff reductions could reduce our profit margins or otherwise negatively impact our revenue from certain products, including a small number of significant products. The Chinese government may also reduce the tariffs imposed on production equipment that we may import in the future.

Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business and results of operations.

Substantially all of our operations are conducted in China. Accordingly, our business, prospects, financial condition and results of operations may be influenced to a significant degree by political, economic and social conditions in China generally and by continued economic growth in China as a whole.

The Chinese economy differs from the economies of most developed countries in many respects, including the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over China’s economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, and providing preferential treatment to particular industries or companies.

While the Chinese economy has experienced significant growth over the past decades, growth has been uneven, both geographically and among various sectors of the economy. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. 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. In addition, the Chinese government has implemented in the past certain measures, including interest rate increases, to control the pace of economic growth. These measures may cause decreased economic activity in China, and since 2012, China’s economic growth has slowed down. Any prolonged slowdown in the Chinese economy may reduce the demand for our products and services and materially and adversely affect our business and results of operations.

Interpretation and enforcement of Chinese laws and regulations is uncertain.

The Chinese legal system is based on statutory law. Under this system, prior court decisions may be cited as persuasive authority, but do not have the binding effect of precedents. Since 1979, the Chinese government has been developing a comprehensive system of commercial laws and considerable progress has been made in the promulgation of laws and regulations dealing with economic matters, such as corporate organization and governance, foreign investment, commerce, taxation and trade. Because these laws, regulations and legal requirements are relatively new or otherwise undeveloped and not all accessible to the public and because prior court decisions have little precedential value, the interpretation and enforcement of these laws, regulations and legal requirements involve greater uncertainty than in other jurisdictions.

Cyber attacks and security breaches may threaten the integrity of our intellectual property and other sensitive information and disrupt our business operations, which could adversely affect our reputation, business and financial position.

We face global cybersecurity threats, which may range from uncoordinated individual attempts to sophisticated and targeted measures directed at us. Cyber attacks and security breaches may include, but are not limited to, attempts to access information, computer viruses, denial of service and other electronic security breaches.

Although we have not experienced any material cybersecurity incidents in the past, we cannot assure you that we will not experience them in the future. Due to the evolving nature of cybersecurity threats, the scope and impact of any future incident cannot be predicted. While we continually work to safeguard our systems and mitigate potential risks, there is no assurance that such actions will be sufficient to prevent cyber attacks or security breaches that manipulate or improperly use our systems or networks, compromise confidential or otherwise protected information, destroy or corrupt data, or otherwise disrupt our operations. The occurrence of such events could negatively impact our reputation and our competitive position and could result in litigation with third parties, regulatory action, loss of business, potential liability and increased remediation costs, any of which could have an adverse effect on our financial condition and results of operations.

You may not enjoy shareholders’ protections that you would be entitled to in other jurisdictions.

As most of our business is conducted in China, our operations are governed principally by the laws of China. Despite the continuing improvement of the PRC Company Law and Securities Law, Chinese legal provisions for the protection of shareholders’ rights and access to information are different from those applicable to companies formed in the United States, Hong Kong, the United Moreover, there are significant differences between our corporate governance practices and those of U.S. issuers listed on the NYSE, as further described under “Item 16 G. Corporate Governance.” Kingdom and other developed countries or regions. You may not enjoy shareholders’ protections under Chinese law that you would be entitled to in other jurisdictions.

Our Articles of Association require you to submit your disputes with us and other persons defined by our Articles of Association regarding the Company’s affairs to arbitration. You will have no legal right to a court proceeding with respect to such disputes.

Our Articles of Association require holders of our H shares or ADSs having a claim against, or a dispute with, us, our directors, supervisors, executive officers or a holder of our domestic shares relating to any rights or obligations conferred or imposed by our Articles of Association, the PRC Company Law or other relevant Chinese laws or regulations relating to our affairs, to submit such claim or dispute to arbitration with the China International Economic and Trade Arbitration Commission or to the Hong Kong International Arbitration Center. Our Articles of Association further provide that any arbitration decisions with respect to such disputes or claims shall be final and binding on all parties. As a result, you will have no legal right to a court proceeding with respect to such disputes.

Our auditor, like other independent registered public accounting firms operating in China, is not permitted to be subject to inspection by Public Company Accounting Oversight Board and, as such, investors may be deprived of the benefits of such inspection.

Our independent registered public accounting firm that issues the audit reports included in our annual reports filed with the SEC, as an auditor of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board (United States), or PCAOB, is required by the laws of the United States to undergo regular inspections by PCAOB to assess its compliance with the applicable professional standards. Because our auditor is located in China, a jurisdiction where PCAOB is currently unable to conduct inspections without the approval of the PRC authorities, our auditor, like other independent registered public accounting firms operating in China, is currently not inspected by PCAOB.

Inspections of other firms that PCAOB has conducted outside of China have identified deficiencies in those firms’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. The inability of PCAOB to conduct inspections of independent registered public accounting firms operating in China makes it more difficult to regularly evaluate the effectiveness of our auditor’s audit procedures or quality control procedures. As a result, investors may be deprived of the benefits of PCAOB.

Proceedings instituted recently by the SEC against the Big Four PRC-based accounting firms, including our independent registered public accounting firm, could result in our financial statements being determined to not be in compliance with the requirements of the Exchange Act.

In December 2012, the SEC brought administrative proceedings against the Big Four accounting firms, including our independent registered public accounting firm, in China, alleging that they had refused to produce audit work papers and other documents related to certain other China-based companies under investigation by the SEC for potential accounting fraud. On January 22, 2014, an initial administrative law decision, or Initial Decision, was issued, censuring these accounting firms and suspending four of the five firms from practicing before the SEC for a period of six months. The accounting firms filed a petition for review of the Initial Decision to the SEC. On February 6, 2015, the Big Four China-based accounting firms 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 required the firms to follow detailed procedures and to seek to provide the SEC with access to Chinese firms’ audit documents via the China Securities Regulatory Commission (the “CSRC”). If future document productions fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. While we cannot predict if the SEC will further review the four China-based accounting firms’ compliance with specified criteria or if the results of such a review would result in the SEC imposing penalties such as suspensions or restarting the administrative proceedings, if the accounting firms are subject to additional remedial measures, our ability to file our financial statements in compliance with SEC requirements could be impacted. A determination that we have not timely filed financial statements in compliance with SEC requirements could ultimately lead to the delisting of our ADSs from the New York Stock Exchange or the termination of the registration of our H shares under the Securities Exchange Act of 1934, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

We may be or become a passive foreign investment company, which could result in adverse U.S. federal income tax consequences to U.S. investors.

Generally, if, for any taxable year, at least 75% of our gross income is passive income, or at least 50% of the value of our assets is attributable to assets that produce passive income or are held for the production of passive income, we would be characterized as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes. We do not expect to be a PFIC for our current taxable year. However, since PFIC status depends on the composition of our income and the composition and value of our assets from time to time, there can be no assurance that we will not be considered a PFIC for any taxable year. If we are characterized as a PFIC, U.S. investors may suffer adverse tax consequences, including increased U.S. tax liabilities and reporting requirements. For further discussion of the adverse U.S. federal income tax consequences of our possible classification as a PFIC, see Item 10. Additional Information – E. Taxation – U.S. Taxation.

We have in the past sourced a small portion of crude oil from Iran that may be targeted by economic sanctions under relevant U.S. laws, and if such activities are determined by the U.S. governmental authorities as sanctionable activities, we could be sanctioned or otherwise penalized.

The United States has adopted a number of measures since 1996 that provide for the possible imposition of sanctions against non-U.S. companies engaged in certain activities in and with Iran in the energy and other sectors, including Executive Orders 13622 (effective July 31, 2012 and revoked January 16, 2016), 13628 (effective October 9, 2012), and 13645 (effective July 1, 2013 and revoked January 16, 2016), the Iran Threat Reduction and Syria Human Rights Act of 2012 (“ITRSHRA”) enacted August 10, 2012 and the Iran Freedom and Counter-Proliferation Act (“IFCA”) enacted January 2, 2013. The sanctionable activities include certain investments, the provision of goods, services, technology, or support that could contribute to the development of petroleum and petrochemical resources or the production of refined petroleum products in Iran, the exportation of refined petroleum products to Iran, the transportation of crude oil from Iran, or the engagement in a significant transaction for the purchase or acquisition of petroleum or petroleum products from Iran, and the engagement in transactions with certain Iranian specially designated nationals and blocked persons (“SDNs”) as identified and published by U.S. Department of the Treasury’s Office of Foreign Assets Control, or OFAC, the agency primarily responsible for administering U.S. sanctions and embargoes.

We have sourced a small portion of our crude oil from Iran in the past through Sinopec Corp., our current controlling shareholder, and independent third parties, and we may continue to purchase crude oil from Iran. In addition, Sinopec Corp. and Sinopec Group, the controlling shareholder of Sinopec Corp., have engaged in operations in or purchasing crude oil sourced from Iran and may continue to do so in the future. We have no control over the activities of Sinopec Group or Sinopec Corp. in connection with any activities that they may conduct in Iran.

9

If our purchases of crude oil from Iran and transactions related thereto are determined to be sanctionable activities by the U.S. President and/or the relevant U.S. governmental authorities, we may be subject to five or more of the twelve sanctions options available under the Iran Sanctions Act of 1996 (as amended) (“ISA”) and the ITRSHRA, which include restrictions on bank financing, outright blocking of the Company’s property within U.S. jurisdiction, under the control of U.S. persons anywhere in the world, and prohibition of U.S. persons from investing or purchasing a significant amount of equity or debt instruments of the Company. Similar sanctions may also be imposed under the Executive Orders cited above, the IFCA, and other U.S. laws. In addition, many states in the United States have adopted legislation requiring state pension funds to divest themselves of securities in any company with active business operations in Iran. We cannot assure that we or any of our affiliates will not be sanctioned by the U.S. President and/or the relevant U.S. governmental authorities in light of the activities by us or our affiliates in Iran. The imposition of any such sanctions on us or our affiliates will have a negative impact on our business, reputation or stock price. In addition, purchase of crude oil by Sinopec Corp. subsidiaries that supply us with raw materials may from time to time be sourced from National Iranian Oil Company. This entity has been identified by the U.S. government as an SDN and sanctioned under various laws, including for assisting the government of Iran to avoid sanction and for engaging in activities related to nuclear proliferation. Under Executive Order 13645, the U.S. President can sanction non-U.S. companies that prior to January 16, 2016, had engaged in transactions with SDNs such as the National Iranian Oil Company. To the extent we indirectly (or directly) purchase raw materials from this entity, we risk potential U.S. government sanctions. Even absent any U.S. government sanctions, we risk adverse publicity in the world markets, which may impair our reputation and business.

Sinopec Group, the controlling shareholder of Sinopec Corp. which is our current controlling shareholder, or its affiliates’ current or future activities in certain countries are the subject of economic sanctions under relevant U.S. laws and could result in negative media and investor attention to us and possible imposition of sanctions on Sinopec Group, which could materially and adversely affect our shareholders.

Sinopec Group undertakes, from time to time and without our involvement, overseas investments and operations in the oil and gas industry, including the exploration and production of oil and gas, refining and Liquefied Natural Gas, or LNG, projects. Sinopec Group’s overseas asset portfolio includes oil and gas development projects in Iran, Sudan and Syria, countries subject to U.S. sanctions and embargoes. We cannot predict the interpretation or implementation of government policy at the U.S. federal, state or local levels with respect to any current or future activities by Sinopec Group or its affiliates in countries or with individuals or entities that are the subject of U.S. sanctions. Similarly, we cannot predict whether U.S. sanctions will be further tightened, or the impact that such actions may have on Sinopec Group. It is possible that the United States could subject Sinopec Group to sanctions due to these activities. Certain U.S. state and local governments and colleges have restrictions on the investment of public funds or endowment funds, respectively, in companies that are members of corporate groups with activities in certain countries that are the subject of U.S. sanctions. These investors may not wish to invest, and may divest their investment, in us because of our relationship with Sinopec Group and its investments and activities in those U.S. government sanctioned countries. It is possible that, as a result of activities by Sinopec Group or its affiliates in countries that are the subject of U.S. sanctions, we may be subject to negative media or investor attention, which may distract management, consume internal resources and affect investors’ perception of our company.

Further, the ISA authorizes the imposition of sanctions on companies that engage in certain activities in and with Iran, especially in Iran’s energy sector. It is possible that Sinopec Group or its affiliates engage in activities that are targeted for sanction purposes by the ISA or other U.S. laws. If the U.S. President determines that Sinopec Group or one of its affiliates in fact engaged in the targeted activities, he would be required under the ISA to impose on Sinopec Group or its affiliates at least five sanctions from among twelve sanctions options available under the ISA, which range from restrictions on U.S. exports or bank financing to outright blocking of Sinopec Group or its affiliate’s property within the U.S. or in the possession or control of U.S. persons anywhere in the world. In addition, the IFCA requires the U.S. President to block the property of persons and entities within U.S. jurisdiction or control of U.S. persons if he determines that, among other things, such persons or entities are engaged in certain transactions involving the energy, shipping or shipbuilding sectors of Iran or with certain SDNs. It also requires the U.S. President to impose five or more sanctions under the ISA on a person that he determines has knowingly, on or after July 1, 2013, sold, supplied or transferred to or from Iran precious metals or certain other materials (including graphite, aluminum, steel, coal and certain software) if used for specified purposes. If the U.S. President determines that Sinopec Group, or an entity it owns or controls, prior to January 16, 2016,had engaged in any such activities and if the most extreme sanction under the ISA or other U.S. sanctions laws, blocking, were applied to Sinopec Group’s property, including controlled subsidiaries, Sinopec Group could be prohibited from engaging in business activities in the United States or with U.S. individuals or entities, and U.S. transactions in our securities and distributions to U.S. individuals and entities with respect to our securities could also be prohibited.

In addition, pursuant to the IFCA, Executive Order 13645 and other U.S. laws, the U.S. government can sanction financial institutions anywhere in the world that engage in certain Iran related transactions. Such sanctions include prohibiting the financial institution from opening, or imposing strict conditions on maintaining, a correspondent or payable through account in the United States. The potential for financial institutions to be sanctioned for Iran related activities may impact our ability to engage in financial transactions related to Iran transactions. Although many of the sanctions discussed above were terminated on January 16, 2016 pursuant to the commitments of the United States under Joint Comprehensive Plan of Action, such termination would not affect sanctionable activities occurring prior to that date.

The trading prices of our ADSs and H Shares have been volatile and may continue to be volatile regardless of our operating performance.

The trading prices of our ADSs and H Shares have been and may continue to be subject to wide fluctuations. The market price for our ADSs may continue to be volatile and subject to wide fluctuations in response to factors including the following:

• actual or anticipated fluctuations in our quarterly results of operations;

• changes in financial estimates by securities research analysts;

• conditions in petroleum and petrochemical markets;

• changes in the operating performance or market valuations of other petroleum and petrochemical companies;

• announcements by us or our competitors of new products, acquisitions, strategic partnerships, joint ventures or capital commitments;

• fluctuations of exchange rates between RMB and the U.S. dollar; and

• general economic or political conditions in China or elsewhere in the world.

In addition, the stock market in general, and the market prices for companies with operations in China in particular, have experienced volatility that often has been unrelated to the operating performance of such companies. The securities of some China-based companies that have listed their securities in the United States have experienced significant volatility since their initial public offerings in recent years, including, in some cases, substantial declines in the trading prices of their securities. The trading performances of these companies’ securities after their offerings may affect the attitudes of investors towards Chinese companies listed in the United States in general, which consequently may impact the trading performance of our ADSs, regardless of our actual operating performance. In addition, any negative news or perceptions about inadequate corporate governance practices or fraudulent accounting, corporate structure or other matters of other Chinese companies may also negatively affect the attitudes of investors towards Chinese companies in general, including us, regardless of whether we have engaged in any inappropriate activities. In particular, the global financial crisis and the ensuing economic recessions in many countries have contributed and may continue to contribute to extreme volatility in the global stock markets. These broad market and industry fluctuations may adversely affect the market price of our ADSs.

ITEM 4. INFORMATION ON THE COMPANY.

A. History and Development of the Company

General Information

We were established in the People’s Republic of China as a joint stock limited company under the PRC Company Law on June 29, 1993 as Shanghai Petrochemical Company Limited. On October 12, 2000, we changed our name to Sinopec Shanghai Petrochemical Company Limited. Our registered office is at No. 48 Jinyi Road, Jinshan District, Shanghai, China 200540. Our telephone number there is (86-21) 5794-1941.

Our Predecessor

Our predecessor, Shanghai Petrochemical Complex (the “Complex”), was founded in 1972 as one of the first large scale Chinese petrochemical enterprises using advanced imported technology and equipment. Prior to June 29, 1993, the Complex was wholly-owned by Sinopec Group, at the time a ministerial level enterprise (before its restructuring in 1998, “Sinopec”). The Complex’s location was chosen because of accessibility by water and land transportation to Shanghai, a major industrial city of China, and the availability of reclaimable land. The Complex was initially under the administration of the Ministry of Textile Industry and in 1983 was placed under the administration of Sinopec.

Construction Projects

The Complex and we, as its successor, have completed six major stages of construction. The first stage of construction (1972-1976) included reclamation of land and the installation of 18 production units. The second stage of construction (1980-1986) increased the Complex’s capacity for processing crude oil and doubled its capacity for synthetic fiber production. The third stage of construction (1987-1992) primarily consisted of the installation of a 300,000 ton Rated Capacity ethylene unit, an additional crude oil refining unit and other units for the production of petrochemical products. The third stage of construction completed our transition from a synthetic fiber producer to a highly integrated producer of a wide variety of petrochemical products. The fourth stage of construction (2000-2002) mainly included the 700,000 ton Ethylene Expansion Project and Coal-Fired Power Plant Expansion Project. The fifth stage of construction (2003-2009) was mainly designed to optimize our structure and realize sustainable development, and mainly included 3,300,000t/a diesel hydrogenation unit, 1,200,000t/a delayed coking unit and other projects implemented for removing “bottlenecks” in refinery, the building of new 600,000t/a PX hydrocarbon complex unit, 150,000t/a C5 segregation unit, 380,000t/a ethane unit, etc.

11

The Company commenced the sixth stage of construction in 2010 (the “Phase 6 Project”) and completed the project in December 2012. The key component of the Phase 6 Project was the refinery revamping and expansion project. The Phase 6 Project also included the technology development and fine chemicals projects. The purpose of the Phase 6 Project was to improve the Company’s overall industrial structure, core competitiveness and the capability of maintaining sustainable developments. The Phase 6 Project was focused on the objective to achieve intensive utilization of natural resources and the build-up of a complete set of facilities, in accordance with the fundamental industrial model of integrating oil refining and petrochemical production. Through this project, the Company further enhanced its oil refining process and strengthened and expanded the Company’s core businesses while continuing to explore the development of fine chemicals and products with high value added.

Over the past four decades, the Company has built up an infrastructure system to support its production needs. The Company has its own facilities to supply water, electricity, steam and other utilities and to treat waste water, as well as ocean and inland waterway wharfs and railroad and road transportation facilities.

Our Initial Public Offering and Listing

We were established as a subsidiary of Sinopec on June 29, 1993. In preparation for our initial public offering of ordinary shares, all assets and liabilities of the Complex were transferred either to us or to Sinopec Shanghai Jinshan Industrial Company (“JI”), a separate subsidiary of Sinopec. The Complex’s non-core businesses and assets, such as housing, stores, schools, transportation and medical services, were transferred to JI. The Complex’s core business and assets were transferred to us. The Complex then ceased to exist as a legal entity. In 1998, Sinopec was restructured into a limited liability company under the name of China Petrochemical Corporation (“Sinopec Group”). On February 25, 2000, Sinopec Group transferred its interest in us to its subsidiary, Sinopec Corp. In 1997, JI was restructured and its subsidiaries were either transferred to Sinopec or Shanghai Jinshan District. Sinopec Group now provides community services to us that were formerly provided by JI.

Our H Shares commenced listing on the HKSE on July 26, 1993. Our ADSs, each representing 100 H Shares, are listed on the New York Stock Exchange (“NYSE”). Our domestic shares are listed on the Shanghai Stock Exchange. We were the first Chinese joint stock limited company to have securities concurrently traded in Hong Kong, the United States and China. On November 8, 1993, our domestic shares were included in the Shanghai Stock Exchange Stock Index.

Domestic Share Reform

Pursuant to regulations issued by the CSRC, we were required to obtain shareholder approval for and implement certain share reform. As a result of such share reform, all non-publicly tradable domestic shares of the Company would be converted into publicly tradable domestic shares and may be sold publicly on the Shanghai Stock Exchange subject to any applicable lock-up period.

In connection with the share reform, the Distribution Proposal regarding 2013 Interim Distribution of Cash Dividend and the Conversion of Capital Fund and Surplus Reserve into Shares of the Company (“Proposal”) was approved at the Company’s 2013 First Extraordinary General Meeting, 2013 First A Shareholders Class Meeting and 2013 First H Shareholders Class Meeting held on October 22, 2013. According to the Proposal, based on the Company’s total share capital of 7,200,000,000 shares as of June 30, 2013, RMB2,421 million of the capital surplus of the Company from its share premium account was used to fund the issue of 3.36 new bonus shares with respect to every 10 issued and outstanding shares, the surplus reserve was used to fund the issue of 1.64 new bonus shares with respect to every 10 issued and outstanding shares, and an interim cash dividend of RMB0.50 (tax included) for every 10 issued and outstanding shares was distributed to all shareholders.

In addition, Sinopec Corp. undertakes under the Proposal that it shall not, within 12 months from the date on which Sinopec Corp. becomes entitled to trade, deal in or transfer its non-publicly tradable shares of the Company in the market (meaning the first trading day after the implementation of the Proposal), trade such shares in the market. Also, after the expiration of the aforesaid 12-month term, the amount of existing non-publicly tradable shares to be disposed of by Sinopec Corp. through trading on the stock exchange shall not represent more than 5% of the total number of our shares held by Sinopec Corp. within the next 12 months, and not more than 10% within the next 24 months.

Immediately upon completion of the conversion of capital surplus and surplus reserve into new shares of the Company, the total number of domestic shares of the Company reached, as of December 4, 2013, 7,305,000,000, and the total amount of H Shares of the Company reached 3,495,000,000. Therefore, the Company’s total share capital consists of 10,800,000,000 shares. Sinopec Corp., being the controlling shareholder of the Company, holds 5,460,000,000 domestic shares, representing 50.56% of the total share capital of the Company.

The share certificates of new H Shares issued in connection with the share reform were dispatched and the cash dividend was paid to the holders of H Shares on December 4, 2013. The dealings in the new H Shares commenced on December 5, 2013.

Production Processes

The key component of the vertically integrated production facility of the Company is the ethylene facility producing ethylene and propylene and aromatics facility mainly producing paraxylene and benzene. Ethylene is the main raw material for the production of polyethylene and ethylene glycol, while ethylene glycol and PTA polymerization produces polyester. Propylene is the main raw material for the production of acrylics and polypropylene. The above-mentioned products all use crude oil as raw material and are processed through a series of petrochemical facilities. The chart below illustrates in brief the production processes of the Company.

19

20

Intermediate Petrochemicals

Ethylene – Ethylene is either directly processed into polypropylene resins or processed into other intermediate petrochemicals. The most important of these is MEG. MEG is a key ingredient in polyester. It is produced by oxidizing ethylene in the ethylene oxide /ethylene glycol unit. Ethylene is also used to produce vinyl acetate which is processed into PVA.

Propylene – Propylene is either processed directly into polypropylene resins or is further processed into other intermediate petrochemicals such as acrylonitrile, acetonitrile, hydroxyl acetonitrile and sodium cyanide. Acrylonitrile is used in producing acrylics.

Vacuum gas oil – VGO is passed through the hydrocracker, and the resulting heavy naphtha is fed into the aromatics plants to produce PX and benzene. PX is processed into PTA, one of the principal raw materials in producing polyester.

Resins and Plastics and Synthetic Fibers

We process our intermediate petrochemical products into five kinds of synthetic fiber raw materials: (1) polyester, (2) acrylonitrile, (3) polypropylene, (4) polyethylene, and (5) PVA. Each of these five products has its own production line or lines. We further process polyester and acrylonitrile into various types of synthetic fibers.

Polyester – MEG and PTA are fed into a polymerization unit which produces polyester chips and polyester melt. Both chips and melt are used as raw materials in the production of polyester staple and filaments. Some chips are also sold to third parties.

Polyester staple fiber is a multi-strand fiber cut into short lengths which can be spun into fabric on its own or blended with cotton, wool or flax to produce textiles. Polyester filaments are a class of more highly processed polyester materials which have been drawn and oriented to produce a long thread-like fiber.

Acrylonitrile – We produce polyacrylonitrile by feeding acrylonitrile into a polymerization unit. By passing the polyacrylonitrile through the fiber unit, acrylic fiber and acrylic staple fiber are produced, including cotton and wool type staple fibers. Wool acrylic staple fiber can be processed into acrylic wool strips.

Polypropylene – We produce polypropylene resins by feeding propylene into a polymerization unit. Our fiber grade polypropylene resin is the main ingredient for polypropylene fiber production.

Polyethylene – We have three sets of units producing polypropylene, two of which produce low-density polyethylene (“LDPE”) using the kettle type process, and the other unit produces all density polypropylene products using the Borstar bimodal process.

PVA – PVA granules are produced from vinyl acetate, derived from ethylene.

Raw Materials

In 2017, we continued to strengthen our advantages in refining and chemical integration and leverage the strong adaptability of our refining plants to process more high-sulfur crude oil; we used a Process Industry Modeling System to determine the cost performance of crude oil to further improve the cost control of crude oil purchases; and the total volume of the top ten main types of oil purchased in the whole year of 2017 accounted for 100% of the total purchase of crude oil, and as a result of the increased concentration, the overall cost of crude oil we purchased reduced.

To enhance the overall profitability, we optimized our ethylene cracking stocks, adjusted and improved our natural gas and fuel gas structure, optimized our hydrogen system, reduced the emission and increased the efficiency of flare gas, increased the outputs of gasoline and aviation kerosene, and optimized naphtha, residual oil and wax oil processing lines. By reducing the output of paraxylene, we increased our supply of high-octane gasoline blending components to produce more gasoline. By substituting aviation kerosene hydrogenation for diesel hydrogenation and upgrading the quality of 3.3 million tons of diesel through hydrogenation, we further optimized the structure of our finished oil products, achieving a diesel to gasoline ratio of 1.22:1 for 2017. We strengthened our tracking of the margin contribution of our units, and continuously carried out daily profitability measurement for each product so as to promptly detect changes in profitability, quickly adjust the load and running schedule of our production units and afford priority to the production of products with high profitability and market demand.

Crude Oil

Crude oil is our primary raw material and the most significant raw material we purchase from outside sources. In 2017, crude oil accounted for approximately 45.45% of our total cost of sales. Accordingly, the supply and price of crude oil are key factors in determining our profitability.

21

Supply and Transportation – All crude oil required by us, whether from domestic or foreign sources, is purchased through the channels of Sinopec Corp. as an agent. During 2017, we did not experience any significant problems in obtaining sufficient crude oil to meet our production needs.

Sinopec Group is responsible for preparing an annual plan on demand and supply for crude oil and petroleum products that forms the basis of the Chinese government’s annual “balancing plan” which effectively dictates our planned volume of crude oil processing in each year. Likewise, under the “balancing plan,” some of our petroleum products are designated for sale to the subsidiaries of Sinopec Group or other designated customers at market prices and we must consult Sinopec Group to sell elsewhere.

We have received confirmation from Sinopec Corp. that it will purchase on our behalf 14.35 million tons of imported crude oil in 2018. Sinopec Corp. has further confirmed that, subject to China’s national crude oil policy and our actual production needs, it will continue to purchase on our behalf sufficient quantities and appropriate types of crude oil, including domestic offshore and imported crude oil, to satisfy our anticipated annual needs. We anticipate that we will fully utilize our supply of crude oil in 2018. We believe that the mix of crude oil feedstock currently available is satisfactory for our 2018 production capacity and targets. Additionally, as part of China’s commitment at its accession into WTO, certain non-state-owned enterprises have been granted an increasing amount of quota to import crude oil. Although we do not expect to obtain crude oil through this channel in the foreseeable future due to the current crude oil supply system, this may provide us with an alternative source of crude oil supply.

Crude Oil Mix – Our refining equipment is designed to process certain grades of crude oil. Therefore, the origin and quality of the crude oil available can be important to our business. We believe that as we have been significantly increasing usage of imported crude oil, we will continue to be able to obtain from the market such imported crude oil that is compatible with our refining equipment. The overall mix of foreign versus domestic crude oil we process in 2018 will depend on a variety of factors, including the amount of future supply of domestic offshore crude oil and the availability, price, quality, processing profitability and compatibility with our refining capabilities of imported crude oil. Provided there are no significant modifications to the existing channels of crude oil supply, we believe that sufficient supplies of crude oil will be available on the domestic or international markets for our 2018 production capacity and goals.

In 2017, our crude oil was sourced as follows:

Domestic offshore crude oil	0.97	%
Imported crude oil	99.03	%
Total:	100.00	%

We expect that we will continue to rely principally on foreign sources for our crude oil supply. However, we believe that we will be able to maintain our processing efficiency through technological adjustments of our equipment and quality control and that increased use of imported oil will not materially adversely impact our business and results of operations.

Foreign and domestic offshore crude oil is supplied by tanker and pipeline to our oil terminal wharf and oil storage tank. See Item 4.D. Property, Plants and Equipment -Wharfs.

In the past, we have not experienced disruption in our crude oil supply. We have on-site crude oil storage tanks at Chenshan wharf capable of storing approximately 300,000 cubic meters of crude oil, primarily to provide crude oil to our No. 2 atmosphere vacuum distillation facility. This crude oil storage can provide us with approximately a 2-week supply of crude oil. The crude oil for our No. 3 atmosphere vacuum distillation facility is mainly supplied from the Ningbo-Shanghai-Nanjing oil pipeline. Due to our ability to obtain crude oil from multiple sources, we are able to meet our normal requirements for crude oil.

Pricing – The price of domestic crude oil shall apply the market –adjusted rate and the imported crude oil is generally sold to us at prevailing international market prices. The average cost of imported crude oil and domestic offshore crude oil in 2017 was RMB2,577.75 (U.S.$ 396.19) per ton and RMB2,969.06 (U.S.$456.34) per ton, respectively. In 2017, we processed 14.24 million tons of imported crude oil and 0.12 million tons of domestic offshore crude oil (including 1.61 million tons of crude oil processed on a sub-contract basis).

Until March 2001 the Chinese government implemented a unified pricing system for crude oil. Each month, the National Development and Reform Commission (“NDRC”) established an indicative price for each grade of domestic onshore crude oil based on comparable international market prices, inclusive of any duties that would have been imposed had the oil been imported. The actual price for domestic onshore oil would be such indicative price plus a surcharge. This surcharge was determined by China National Petroleum Corporation and Sinopec Group to reflect any transportation and other miscellaneous costs that would have been incurred in having the oil delivered to various refineries. Beginning March 2001, NDRC ceased publishing an indicative price. Instead, the indicative price for domestic onshore oil has been calculated and determined directly by China National Petroleum Corporation and Sinopec Group based on the principles and methods formerly applied by NDRC.

22

On January 13, 2016, NDRC issued the Circular on Several Issues on Further Improving the Pricing Mechanism of Refined Oil (Fa Gai Jia Ge [2016] No. 64) to adjust the existing refined oil pricing mechanism, which include, among other things, (i) setting a price floor of U.S.$40 for the downward adjustment of the crude refined oil. When the international crude oil price drops to U.S.$40 per barrel or below, i.e., the adjustment price floor, the refined oil price in China shall no longer be adjusted downwards; and (ii) creating a reserve for risks associated with the adjustment and control of oil prices. When the international crude oil price drops to U.S.$40 per barrel or below, all unadjusted amount shall be allocated to the reserve abovementioned for use for the purpose of energy saving or reduction of emission, improving the oil quality and securing a safe supply of oil.

We purchase crude oil through Sinopec Corp. and its affiliates from the sources selected and in the quantities confirmed by the Company at market prices. On this basis, we believe that changes in crude oil prices should not have a material effect on our competitiveness with other domestic producers. Nevertheless, any increase in the price of crude oil could have an adverse impact on our profitability to the extent that we are unable to pass cost increases on to our customers.

In 2017, the world economy had shown strong recovery with accelerated growth of developed economies and overall growth rally of emerging and developing economies. Price of global commodity had steadily risen and international trade had picked up growth. In 2017, the average West Texas Intermediate crude oil price on the U.S. mercantile exchanges was U.S.$50.92/barrel, representing an increase of 17.44% from U.S.$ 43.36/barrel in 2016. In 2017, the average price of Brent crude oil on the London Intercontinental Exchange was U.S.$54.79/barrel, representing an increase of 22.99% from U.S.$ 44.55/barrel in 2016; and in 2017, the average price of crude oil in Dubai was U.S.$53.45/barrel, representing a decrease of 27.47% from U.S.$ 41.93/barrel in 2016.

For the year ended December 31, 2017 we processed a total of 14.4 million tons of crude oil (including 1.6 million tons of crude oil processed on a sub-contract basis), representing a slight increase of 50,000 tons, or 0.35%, over the previous year. Of the crude oil we processed in 2017, domestic offshore oil accounted for 0.12 million tons and imported crude oil accounted for 14.24 million tons. After the launching of the refinery revamping and expansion project as part of Phase 6 Project in 2012, we enhanced the adaptability of the crude oil and significantly improved the ability to process the relatively low-cost high-sulfur crude oil in 2017. The average unit cost of crude oil processed (by us) in 2017 was RMB2,581.35/ton (RMB1,979.58 /ton in 2016), representing an increase of 30.40% over the previous year. Our total cost of crude oil processed reached RMB32.90 billion in 2017, representing an increase of 41.89% as compared to RMB23.19 billion in 2016, which represented 45.45% of the total cost of sales.

Coal

Most of the coal used for electricity generation is purchased through a unified system of procurement by Sinopec Corp., and the rest is purchased directly by us from mines. Coal is transported by rail from the mines to Qinhuangdao port and shipped by barge to Jinshanwei where it is delivered to the plant via a wharf and conveyer system. Our cost is primarily dependent on coal price and transportation charges. Although coal may be purchased from alternative sources, railroad transportation must be obtained by allocation from the Chinese government on a monthly basis.

We expect that our total requirement for coal to generate electricity in 2018 will be approximately 2.00 million tons. In 2017, we consumed approximately 1.98 million tons of coal, a decrease from 2016 of 2.01 million tons.

Other Raw Materials

We produce most of the raw materials used as feedstock for our operations. If any of these raw materials, other than ethylene, becomes unavailable from internal production, we believe that there are sufficient alternative sources at reasonable prices and the unavailability of raw materials from internal sources will not have a significant effect on our operations and profitability.

We purchase some ancillary raw materials from outside sources. These raw materials include natural gas, MX, methanol, ammonia, sodium hydroxide, sulfur, acetone, acrylonitrile, PTA, propylene and a variety of catalytic agents. In 2017, the total cost of these materials accounted for approximately 12.67% of our total cost of sales. We do not expect any difficulties in obtaining a supply of any of these ancillary raw materials in amounts sufficient to meet our needs in the foreseeable future.

Sales and Marketing

Distribution

The distribution of our fuel products is subject to government regulations. We are required to sell certain refined products to the subsidiaries of Sinopec Group or customers designated by Sinopec Group. Since the second half of 2005, Sinopec Group has executed reforms to its system of selling petrochemical products and implemented what it refers to as a “Five Consolidations” strategy featuring “consolidated marketing strategy, consolidated promotion, consolidated logistics optimization, consolidated sales and consolidated branding.” As a result, the sales of our major petrochemical products are now conducted in a consolidated manner by sales agents designated by Sinopec Group. However, we have the autonomy to decide on the distribution method of our other products in accordance with market conditions. The products we sold in 2017 that were subject to planned distribution by Sinopec Group, sales by agents and sales based on our own discretion accounted for 55.04%, 36.74% and 8.22%, respectively, of the total products we sold.

23

We generally sell our products to larger trading companies and industrial users with whom we have long-standing relationships, including Sinopec Group or customers designated by Sinopec Group. We believe that the transition to sales of major petrochemical products by agents designated by Sinopec Group will increase our distribution efficiency, reduce horizontal competition and enhance our overall bargaining power, by allowing us to benefit from Sinopec Group’s extensive and highly specialized sales network. It will also allow us to focus more of our resources on reducing production costs and enhancing our technical support.

We use long term contracts to sell most of our products. We did not experience significant write-offs or defaults on our accounts receivable or other trading accounts in 2017. In general we managed to maintain a stable correlation between production and sales in 2017.

Product breakdown

Synthetic Fibers – In 2017, 31.2% of our synthetic fiber products were purchased by provincial and municipal government trading companies that act as intermediaries between us and end-users. No single customer accounted for more than 20% of our sales of synthetic fibers in 2017.

Product Pricing

Most of our products are permitted to be sold at market prices. However, four types of petroleum products (gasoline, diesel and jet fuel, and liquefied petroleum gas) that we sell are subject to varying degrees of government pricing control and are, accordingly, sold at prices set by the Chinese government, which may sometimes be below our costs. In 2015, 2016 and 2017, approximately 40.81%, 53.49% and 57.75% of our net sales, respectively, were from products subject to price controls. Price controls may apply to these products in various ways. Such price controls are sometimes applied exclusively to our products, exclusively to our competitors’ products or sometimes applied to neither our products nor our competitors’ products. The Chinese government has adopted changes to the pricing mechanism for domestic refined oil to be indirectly aligned with international crude oil prices in a controlled manner through use of certain formula(s).

For products that are not subject to price controls, we set our prices with reference to prices in the major Chinese chemical commodities markets in Shanghai and other parts of China. We also monitor pricing developments in major international commodities markets, particularly in Southeast Asia. In most cases, we revise product prices each month, or more frequently during periods of price volatility. Due to our economies of scale, brand recognition and high quality of products, we believe that we can continue to price our products competitively.

Competition

We compete principally in the Chinese domestic market where 94.9% of our products in volume were sold in 2017. In addition, we believe the limitation in transportation infrastructure in China and the difficulties involved in transporting petrochemical products force petrochemical companies in China, including us, to compete primarily on a regional basis. In 2017, 92.7% of our net sales were made to customers in Eastern China.

Our Competitive Advantages

We believe our primary competitive advantages are quality of product, pricing, brand recognition, geographic location and vertical integration. We have received many prizes and awards from both central and local government authorities for high product quality. Furthermore, our location on the outskirts of the densely populated and highly industrialized Shanghai area places us in close proximity to many of our customers. This location also gives us convenient access to ocean transport and inland waterways, which results in a competitive advantage in terms of transportation cost and reliability and punctuality of product delivery.

We believe that our vertical integration in business model represents a significant competitive advantage over non-integrated competitors in China, both in terms of reliability in delivery and price. For most downstream products, our vertical integration results in significant savings on transportation and storage costs which would be incurred by less vertically integrated facilities.

The Domestic Competitive Environment

Prior to 1993, because distribution and pricing of our products were determined in accordance with the state plan, we did not operate in a competitive environment. With the liberalization of control over pricing and product allocation by the Chinese government, competition in the domestic market has been gradually increasing. At the same time, Chinese private enterprises have gradually overcome technological and funding barriers to extend their business from the downstream processing sector to the upstream petrochemical field. These enterprises have advantages in many areas such as flexibility in operation costs, preferential policy treatment and regional presence, and may use these advantages to compete with us in markets for our products.

Foreign Competition and the World Trade Organization

China joined the WTO on December 11, 2001. As part of its membership commitments, China agreed to eliminate certain tariff and non-tariff barriers to foreign competition in the domestic petrochemical industry that benefited us in the past. In accordance with its WTO commitments, China:

• has reduced tariffs on imported petrochemicals products that compete with ours;

• increased levels of permitted foreign investment in the domestic petrochemicals industry, allowing foreign investors to own 100% of a domestic petrochemicals company from December 11, 2004;

• has gradually relaxed restrictions on the import of crude oil by non-state owned companies;

• has granted foreign-owned companies the right to import petrochemical products; and

• has permitted foreign-owned companies to distribute and market fuel products in both retail and wholesale markets in China.

25

As a result of these measures, we are facing increasing competition from foreign companies and imports. On the other hand, we think that China’s WTO entry and increasing foreign investments in China have contributed and will continue to contribute to the growth of investment and business in China, resulting in an increase in sales opportunities for us.

Our Competitive Position

In the following discussion, internal consumption of resins and intermediate petrochemicals produced by integrated manufacturers in the production of downstream products are treated as sales.

Synthetic Fibers

In 2017, we had an approximate 0.44% share of total domestic polyester and acrylic consumption while imports had an approximate 1.18% share.

26

Intermediate Petrochemicals

In 2017, we were one of the largest sellers of intermediate petrochemicals in China, holding an approximate 3.24% share of total domestic consumption, while imports had an approximate 26.68% share of domestic consumption. Ethylene glycol, paraxylene, benzene and butadiene are our major intermediate petrochemical products. In 2017, we were a major producer of ethylene glycol, paraxylene and benzene in China. The following table summarizes the competitive position of our principal intermediate petrochemicals according to domestic sales in 2017.

Product	Our share of domestic consumption			Our competitive ranking		Location of principal domestic competitor	Principal Domestic competitor’s Share of consumption			Imports’ share of consumption

Petroleum Products

In 2017, we had an approximate 2.38% share of total domestic petroleum products market while imports had an approximate 6.09% share. Although we have one of the largest refining capabilities in China, we use most of our refining capacity to produce feedstock for our own downstream processing of petrochemical products.

27

The domestic markets for each of our major petroleum products are geographically concentrated because these markets tend to be highly localized with individual producers controlling a large share of the markets in their locality. In 2017, we sold approximately 92.68% of our petroleum products in Eastern China.

Investments

We established SECCO, a Sino-foreign equity joint venture, in late 2001 with BP and Sinopec Corp., primarily to build and operate a 900,000 ton Rated Capacity ethylene petrochemical manufacturing facility. SECCO completed construction and commenced its manufacturing operations in 2005. In 2009, SECCO had expanded the capacity of certain facilities to 1,090,000 tons of ethylene per annum. We own 20% of the equity interest of SECCO, while BP and Sinopec Corp. own 50% and 30% interests in SECCO, respectively. In October 2017, BP transferred its 50% equity interests in SECCO to a subsidiary of Sinopec Corp., Sinopec Shanghai Gaoqiao Petrochemical Co., Ltd.. As a result of equity transfer, we, Sinopec Corp. and Sinopec Shanghai Gaoqiao Petrochemical Co., Ltd. own 20%, 30% and 50% interests in SECCO, respectively, and SECCO was converted into a PRC domestic company. The registered capital of SECCO is RMB7,800,811,272.00, all of which had been fully contributed by the shareholders in accordance with their equity percentages in SECCO as of October 18, 2017.

In 2017, SECCO achieved a sales revenue of RMB29.18 billion (U.S.$4.48 billion), representing an increase of 22.67% from its sales revenue of RMB23.78 billion (U.S.$3.43 billion) in 2016. SECCO produced 1.25 million tons of ethylene in 2017, representing a slight decrease of 0.02 million tons over the previous year. SECCO had a net profit of RMB5.2 billion (U.S.$799.23 million) in 2017 , representing an increase of RMB1.4 billion (U.S.$218.40 million), or 38.13% over the previous year. The net profit was primarily because SECCO’s production facilities were operated safely and stably in 2017 and realized a high production/sale ratio.

Environmental Protection

We are subject to national and local environmental protection regulations, which currently impose a graduated schedule of fees for the discharge of waste substances, require the payment of fines for pollution and provide for the forced closure of any facility that fails to comply with orders requiring it to cease or cure certain environmentally damaging practices. We have established environmental protection systems which consist of pollution control facilities to treat certain of our waste materials and to safeguard against accidents. Because of the nature of our business, however, we store a significant amount of waste substances in the plants and discharge them into the environment after making such waste substances meet the discharge standards. During 2017, we were assessed a total of RMB109.3 million (U.S.$16.8 million) in fees for discharges of waste substances.

We were subject to various administrative penalties for its violations of the relevant PRC environmental laws and regulations in the past three years. In 2017, we were subject to 19 administrative penalties for violations of the relevant PRC environmental laws and regulations, with fines in a total of RMB3.3 million and ranging from RMB35,000 to RMB650,000.

We believe our environmental protection facilities and systems are adequate for the existing national and local environmental protection regulations. In 2017, we continued to carry out various energy-saving and emissions reduction measures in accordance with the relevant domestic energy conservation and emissions reduction requirements, and achieved all energy-saving and emissions reduction goals set by the Chinese government during the year.

During 2017, the Company’s overall level of energy consumption per RMB10,000 of product value was 0.769 ton of standard coal, decreased by 1.03% from the previous year. As compared with 2016, the total volume of chemical oxygen demand discharged was decreased 4.06%, while that of ammonia nitrogen, sulfur dioxide, nitrogen oxides and volatile organic compounds declined by 1.97%, 22.97%, 17.66% and 16.87%, respectively. At the same time, the compliance rate of waste water and waste gas emissions reached 100%, and all hazardous waste was disposed of properly at 100%. The average heat efficiency of heaters increased 0.14% to 92.54% due to the load reduction.

Insurance

We currently participate in a package of insurance coverage plan through Sinopec Group as its controlled subsidiary, which, as of December 31, 2017, was approximately RMB42.4 billion (U.S.$6.5 billion) on our property and facilities and approximately RMB1.9 billion (U.S.$0.29 billion) on our inventory. In addition, we maintain insurance policies for such assets as engineering construction projects and products in transit with third-party’s commercial insurance company. The Sinopec Group insurance coverage is compulsory and applies to all enterprises controlled by Sinopec Group, pursuant to guidelines of Sinopec Group which may not be legally enforceable against Sinopec Group. Thus, there are uncertainties under Chinese law as to what percentage insurance claims we may demand against Sinopec Group.

We carry a third party liability insurance with a coverage capped at RMB50 million to cover claims, subject to deductibles, in respect of personal injury, property or environmental damage arising from accidents on our property or relating to our operations other than on our transportation vehicles. We have not had a third party liability claim filed against us during the last five years. Since business interruption insurance is not customary in China, we do not carry such insurance.

28

Cyber Security

With respect to our internal internet policies on cybersecurity, we have established an information safety management system and issued internal regulations on cybersecurity, internal hardware and data safety systems and we are gradually implementing measures relating to the office environment information safety management, information system access control, protection from any malicious software, and internal review and audit of information safety risks, in order to prevent loss of information due to cybersecurity incidents, network outages or hardware incidents. In 2017, we did not experience any material cybersecurity incidents or related losses.

Government Regulations

Following the development of several major oil fields and a growth in demand for petroleum and petrochemical products in China in the early 1970s, the Chinese government organized petroleum refining and petrochemical production and processing plants into large complexes that would permit integrated production of petroleum products, intermediate petrochemicals, resins and plastics, and synthetic fibers.

Although the Chinese government is liberalizing its control over the petroleum and petrochemical industries in China, significant government regulations that limit the business strategies available to us remain. Central government agencies and their local or provincial level counterparts do not own or directly control our production plants. However, they exercise significant control over the petrochemical industry in areas such as pricing, production quotas, quality standards, allocation of raw materials and finished products, allocation of foreign exchange and Renminbi loans for capital construction projects. The Chinese government’s intentions with respect to the development objectives and policies for the petrochemical industry are stated as part of the Five Year Plans for National Economic and Social Development formulated every five years. These plans at both the national and Shanghai municipality level have identified the petrochemical industry as a “development industry.”

Historically, we were supervised by Sinopec, a ministry-level enterprise under the direct supervision of the State Council, China’s highest administrative body. As a result of a governmental restructuring in 1998, we became subject to the administration of the State Bureau of Petroleum and Chemical Industry. After its functions were terminated in March 2001, we became subject to the administration of the State Economic and Trade Commission. The State Economic and Trade Commission was dissolved in March 2003 and its function in directing the reform and management of state-owned enterprises was assumed by the State-owned Assets Supervision and Administration Commission, its function in industry planning and policy making was assumed by NDRC, and its functions in administering domestic trade, coordinating and implementing import and export plans of critical industrial products and raw materials were assumed by the Ministry of Commerce. Since then, we have been subject to the industrial oversight of these three governmental agencies at the national level.

As part of this restructuring, Sinopec was also restructured in July 1998. The succeeding entity, Sinopec Group, was authorized to conduct petrochemical business and to control the exploration of crude oil and natural gas and crude oil refining, mainly in the southern and eastern regions of China. China Petroleum and Natural Gas Corporation, another major state-owned petrochemical company, was also restructured, renamed China National Petroleum Corporation and authorized to conduct the same type of business, mainly in the northern and western regions of China. On December 31, 1999, Sinopec Group completed a reorganization pursuant to which certain of its core oil and gas and chemical operations and businesses and related assets and liabilities were transferred to its subsidiary, Sinopec Corp., currently our controlling shareholder.

Business Operations Relating to Iran and other U.S. Sanctioned Countries

In 2017, we sourced a small amount of crude oil from Iran through a wholly-owned subsidiary of Sinopec Corp., our controlling shareholder, and such amount represented 3.56% of our total purchase volume of crude oil. Details of the purchase volume and purchase expenses are provided below:

	Volume (thousand tons)		% of total		Amount (RMB billion)		% of total
Iran		452.68		3.56		1.12		3.39
Others		12,268.79		96.44		31.94		96.61
Total		12,721.47		100.00		33.06		100.00

29

In addition, based on feedback to our inquiries to Sinopec Group, the controlling shareholder of Sinopec Corp., Sinopec Group, directly or indirectly, engaged in a small amount of business activities in Iran such as providing engineering support and designs. Sales revenue from these business activities accounted for 0.00001% of Sinopec Group’s total unaudited sales revenue in 2017. Sinopec Corp. engaged in a small amount of trading activities with an Iranian company with net profit of approximately U.S.$2.32 million in 2017.

We have no performance obligations under any contract to continue to purchase crude oil sourced from Iran in 2018.

Our polyester units use technology from Kanebo Corporation of Japan and E.I. Dupont DeNemours & Co. Inc. of the United States. The polyester staple units use technology from Teijin of Japan and Jima of Germany as well as Chinese technology. The polyester filament units use technology from Murata Manufacturing Company Limited and Teijin Corporation of Japan, Barmag AG of Germany and E.I. Dupont DeNemours & Co. Inc.. We produce polyethylene in three units; two LDPE units which use technology from Mitsubishi Petrochemical Corporation of Japan and BASF LDPE of Germany; and one high-density polypropylene unit uses the Borstar bimodal polyethylene technology from Northern European Chemical Engineering Company.

The acrylic fiber units were built domestically, based on a design of equipment which had been imported into China in the 1960s and that we substantially improved. In 1996, we acquired two additional acrylic fiber units which use technology from the Kawasaki Corporation of Japan. We produce polypropylene in three identical units using technology from Himont Corporation of Italy. The PVA unit uses technology acquired from Kuraray Corporation of Japan.

Power Facilities

Our electricity requirements are currently supplied by our own 425 megawatt coal-fired power plant and petroleum coke power plant. These power plants are designed to provide sufficient power supply needed by our facilities. We are connected to the Eastern China electricity grid, which provides a back-up source of power in case of a shortfall in our self-generated power supply.

Other Facilities

We also have facilities to produce industrial water, steam, hydrogen, oxygen and nitrogen which we use in our production facilities.

Maintenance

We engage in production stoppages for facility maintenance and repairs and implement our routine monthly maintenance and repair plans according to the needs of our production facilities, our requirements for product quality, and our commitment to security and environmental protection. The technicians in our facility management department have responsibility for the daily management of maintenance and repair work. We also outsource facility maintenance and repair projects to qualified contractors.

In 2017, we continued to place emphasis on QHSE by implementing a QHSE responsibility system at each level to strengthen the safety supervision at our operations and construction sites and to improve the QHSE-related performance appraisal. We believe these efforts have resulted in continued improvement in our safety and environmental protection practices. We did not encounter serious accidents involving production safety, environmental pollution or occupational poisoning in 2017. Among the 83 major indicators that measure technical and economic capacity, 41 exceeded those of the previous year while 17 reached advanced levels in our industry.

Transportation-Related Fixtures

Crude oil, our principal raw material, is transported by pipeline and oil tanker to a crude oil terminal wharf and storage tanks. Our products leave the factory by water, rail, road and pipeline. In 2017, approximately 88.7% of our products by sales volume were collected by customers from our premises, and we delivered the balance. Our major ethylene customer is supplied via a pipeline. Some of the products collected by customers were also transported using our facilities.

Wharfs

We own one chemical wharf at Jinshan with five berths of 2,000, 5,000, 8,000, 10,000 and 25,000 tons. We also own a connecting pipeline capable of loading up to approximately 1.4 million tons of chemical products annually onto ocean-going barges and ships. In 2017, products representing 26.6% of total sales volume were shipped from the wharf. We also have a facility to load ships and barges which use the region’s inland waterways. In 2017, products representing 1.5% of total sales volume were shipped from these facilities. We believe that we have a competitive advantage because a greater proportion of our products are shipped by water as opposed to rail and truck, which is subject to capacity constraints on China’s rail and highway networks. Additionally, we own facilities for receiving crude oil and coal at docks that we own and transporting such materials by pipeline or conveyor to our production facilities.

33

Rail

We own a railroad loading depot with an annual capacity of 500,000 tons. The depot provides access via a spur line to the national Chinese railway system. In 2017, products representing 0.24% of total sales volume were transported from the factory by rail. Our ability to transport products by rail is limited because of China’s overburdened railway system, the allocation of use of which remains strictly controlled by the Chinese government.

34

Capital Expansion Program

We have planned or started a number of other principal capital expansion projects. In 2015, 2016 and 2017, we invested RMB0.7 billion, RMB0.8 billion and RMB1.4 billion, respectively, in capital expansion projects. We expect that total investment in the projects described below will be approximately RMB1.2 billion in 2018.

Refining Capacity Expansion

In 2016, we launched No. 2 Diesel Hydrogenation Unit Reconstruction and Diesel Quality Upgrading Project so as to further improve the quality of oil product and perfect oil product structure. In 2017, we launched gasoline upgrade project involving an alkylation plant with a capacity of 300,000 tons/year, which is anticipated to complete in 2019.

Expansion of New and Existing Downstream Petrochemical Products

As a large-scale integrated petrochemical enterprise, we produce a wide range of intermediate and downstream petrochemical products. In order to adapt to the changes in the world’s energy market and the development trends in the oil and chemical products market in China, we will seek to further integrate the existing refining, olefin and aromatic processing chains, and further develop our chemical business.

To take advantage of our specialty in producing acrylics fiber and to improve our industrial structure and upgrade certain products, we plan to construct a carbon fiber project with a capacity of 1,500 tons/year. Sinopec Corp. approved the basic design for this project in December 2010; pile foundation construction was commenced in December 2010; civil engineering was commenced in February 2011 and one series of facilities under phase I were launched for trial operation in 2012. The construction of the second phase of the project was commenced in December 2017.

35

Upgrading Environmental Protection Facilities Projects

To enhance our capacity for sustainable development and response to the government requirements of environmental protection, we intend to increase our capital expenditures on a series of environmental projects, mainly including transformation project for “ultra clean discharge” work in cogeneration unit, transformation of No. 2 olefin cracking burner, environmental protection project for airtight decoking at delayed coking unit 2#, transformation project for the obscuration of burning storage areas of our thermoelectricity department. There projects are anticipated to finish in 2018.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS.

General

You should read the following discussion and analysis in conjunction with our audited financial statements and our selected financial data, in each case, together with the accompanying notes included elsewhere in this annual report. Our audited financial statements have been prepared in accordance with IFRS, as issued by the International Accounting Standards Board.

Critical Accounting Policies

The following discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements. The preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during 2017. Our financial condition and results of operations are sensitive to accounting methods, assumptions and estimates that underlie the preparation of our financial statements. We based our assumptions and estimates on historical experience and on various other assumptions that we believe to be reasonable and which form the basis for making judgments about matters that are not readily apparent from other sources. On an on-going basis, our management evaluates its estimates. Actual results may differ from those estimates as facts, circumstances and conditions change.

Our principal accounting policies are set forth in Note 2 to our consolidated financial statements. The selection of critical accounting policies, the judgments and other uncertainties affecting application of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors to be considered when reviewing our financial statements. We believe the following critical accounting policies involve the most significant judgments and estimates used in the preparation of our financial statements.

Impairments for long-lived assets

Assets that have an indefinite useful life must be tested annually for impairment. Long term assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. In determining the value in use, expected cash flows generated by the asset or the cash-generating unit are discounted to their present value. We use all readily available information in determining an amount that is a reasonable approximation of recoverable amount, including estimates based on reasonable and supportable assumptions and projections of sale volume, selling price and amount of operating costs. During the years ended December 31, 2015, 2016 and 2017, we recognized impairment charges on property, plant and equipment and other long-term assets of RMB50 million, RMB254.2 million and RMB118.2 million, respectively.

Depreciation

Property, plant and equipment are depreciated on a straight-line basis over the estimated useful lives of the assets, after taking into account the estimated residual value. We review the estimated useful lives of the assets annually in order to determine the amount of depreciation expense to be recorded during any reporting period. The useful lives are based on our historical experience with similar assets, taking into account anticipated technological changes. The depreciation expense for future periods is adjusted if there are significant changes from previous estimates. There were no significant changes in these estimates during the years ended December 31, 2015, 2016 and 2017.

Inventory management

At the beginning of every year, the management team determines the appropriate levels of inventories to maintain on the basis of annual production and operating plans, financial budgets and market conditions. Every six months, the management team conducts an inventory status analysis in conjunction with its supply, production, marketing, financial and other departments and develops a plan for keeping inventories at an appropriate level.

36

Management assesses the realizability of our inventories based on the estimates of the net realizable value of the inventories at the end of each reporting period. Net realizable value represents the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale. We base the estimates on all available information, including the current market prices of the finished goods and raw materials and historical operating costs. Any excess of the cost over the net realizable value of each item of inventories is recognized as a provision for diminution in the value of inventories. If the actual selling prices were to be lower or the costs of completion were to be higher than the estimates, the actual allowance for diminution in value of inventories could be higher than estimated. In addition, management periodically reviews inventory aging information to assess if any obsolete inventories are required to be written down at the period end. Based on our assessments, we recorded write-down of inventories of RMB45 million, RMB76 million and RMB60 million, respectively, for the years ended December 31, 2015, 2016 and 2017. Barring unforeseeable changes that may occur to the current economic environment in either China or worldwide, our management does not anticipate encountering major difficulties with our attempt to realize by the end of 2018 the bulk of our inventories as of December 31, 2017 after deducting for diminution in values.

Recognition of deferred tax assets

There are many transactions and events for which the ultimate tax determination is uncertain during the ordinary course of business. Significant judgment is required from us in determining the provision for income taxes in each of these jurisdictions. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

Deferred tax assets are recognized in respect of temporary deductible differences and the carry forward of unused tax losses. We recognize deferred tax assets only to the extent that it is probable that future taxable profit will be available against the assets which can be realized or utilized. At the end of each reporting period, we assess whether previously unrecognized deferred tax assets should be recognized. The Company recognizes a previously unrecognized deferred tax asset to the extent that it is probable that future taxable profit will allow the deferred tax asset to be utilized. In addition, we assess the carrying amount of deferred tax assets that are recognized at the end of each reporting period. The Company reduces the carrying amount of a deferred tax asset to the extent that it is no longer probable that sufficient taxable profit will be available for the deferred tax asset to be utilized.

In making the assessment of whether it is probable the Company will realize or utilize the deferred tax assets, we primarily rely on the generation of future taxable income to support the recognition of deferred tax assets. In order to fully utilize the deferred tax assets recognized at December 31, 2017, the Company would need to generate future taxable income of at least RMB477 million.

We believe that it is probable that the Company will generate sufficient taxable income before the unused tax losses expire. Favorable factors include the enlargement of crude oil refinery capacity of the Company and the new pricing mechanism in the PRC for setting gasoline and diesel prices to more closely track crude oil costs. Uncertainties which could affect the estimated taxable income include various factors such as the volatility of international crude oil prices and the cyclical nature of the petroleum and petrochemical industry. Upon changes in facts and circumstances, management may conclude that deferred tax assets may not be realizable in future periods, resulting in a future reduction in the carrying amount of a deferred tax asset.

Government Policies

The impact of government economic, fiscal, and monetary policies can materially affect our financial condition, results of operations, and cash flows (see Item 3. Key Information - D. Risk Factors).

In particular, we consume large amounts of crude oil to manufacture our products of which more than 95% is typically imported. We attempt to mitigate the effect of increased costs due to rising crude oil prices. However, our ability to pass on these increased costs to our customers is dependent on government regulations, among other factors. Given that the increase of the sales prices of our products can lag behind the increase of crude oil costs, we sometimes fail to completely cover the increased costs by increasing our sales prices, particularly where government regulations restrict the prices of certain of our fuel products such as gasoline, diesel and jet fuel, and liquefied petroleum gas. In 2015, 2016 and 2017, approximately 43.33%, 32.52% and 35.25% of our net sales were from such products subject to price controls. Although the current price-setting mechanism for refined petroleum products in China allows the Chinese government to adjust price in the PRC market when the average international crude oil price fluctuates beyond certain levels within a certain time period (see Item 4. Information on the Company – B. Business Overview – Product Pricing), the Chinese government still retains discretion as to whether or when to adjust the prices of the refined oil products. The Chinese government generally exercises certain price control over refined oil products once international crude oil prices experience a sustained rise or become significantly volatile. Moreover, the Chinese government controls the distribution of many fuel products in China. For instance, some of our fuel products are required to be sold to designated distributors (such as the subsidiaries of Sinopec Corp.). Because we cannot freely sell our fuel products to take advantage of opportunities for higher prices, we may not be able to fully cover increases in crude oil prices by increases in the sale prices of our products, which has had and will continue to have a material adverse effect on our financial condition, results of operations and cash flows.

37

In addition, the exchange rates between the Renminbi and the U.S. Dollar or other foreign currencies are affected by Chinese government policies. In particular, the value of the Renminbi is only permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. The Chinese government continues to receive significant international pressure to liberalize its currency policy. Most of our revenue is denominated in Renminbi, and most of our purchase of crude oil and some equipment and repayment of certain borrowings are made in foreign currencies. Historically, the trend for appreciation of the Renminbi was helpful to us since our imported crude oil purchases constitute such a large portion of our total costs. However, the recent depreciation of the Renminbi increased our costs and affected our capacity of making profits. In addition, any depreciation of the Renminbi could adversely affect the value of the dividends of our H shares and ADSs, which we pay in foreign currencies. Further appreciation in the value of Renminbi against foreign currencies (including the U.S. Dollar) may cause a decrease in the value of our cash and cash equivalents that are denominated in foreign currencies.

A. Results of Operations

In 2017, the world economy had shown strong recovery with accelerated growth of developed economies and overall growth rally of emerging and developing economies. Price of global commodity had steadily risen and international trade had picked up growth. The world economy has grown at a higher rate than in 2016. China had pushed forward supply-side structural reform to continue to release economic vitality, power and potential, which achieved national economy in stable state with good momentum and annual GDP (gross domestic product) growth of 6.9% that was better than expectation. China’s petrochemical industry was operated in stable trend with good momentum with basically steady production, overall stable market demands, risen product price and improved industrial efficiency.

In 2017, centered on overall efficiency and profits of the Company, we made great efforts to seize the favorable market situation and actively carried out safety and environmental protection, optimizing operation, market development and cost reduction, which achieved good results in production and operation and created a high level of economic benefits in history.

39

Year ended December 31, 2017 compared with year ended December 31, 2016

Net sales

In 2017, our net sales amounted to RMB79,218.3 million, increased by 20.14 % compared with 2016. The increase was primarily due to the increase in weighted average sales price of our petroleum and petrochemical products, among which, the weighted average prices (exclude tax) of our synthetic fibers, resins and plastics, intermediate petrochemical products and petroleum products increased by 26.60%, 10.85%, 20.97% and 18.39% over the previous year, respectively. The total volume of our products was 12.6 million tons in 2017, representing an increase of 7.7% over the previous year. Our production/sale ratio was 99.80 %, and the trade receivables recovery rate was 100 %. Our total amount of sales from export was RMB13.85 billion, increased by 16.33 % compared with 2016.

(i) Synthetic fibers

In 2017, our net sales for synthetic fibers amounted to RMB2,005.3 million, representing an increase of 8.07% compared to RMB1,855.5 million in 2016. The increase was primarily due to the increase in price of synthetic fibers, driven by the increase in cost of raw materials. The continued sluggish downstream demand and under-performing initiatives in raw material procurement yet led to a drop in sales volume. Sales volume for synthetic fibers fell by 14.60% compared with the previous year, while weighted average sales price rose 26.60%. In particular, the weighted average sales price of acrylic fiber, the main product of our synthetic fibers, increased by 17.13%, and the weighted average sales price of polyester fiber increased by 21.75% over the previous year. Sales of acrylic fiber and polyester fiber accounted for 83.52% and 8.57% of the total sales of synthetic fibers, respectively.

The net sales of synthetic fiber products accounted for 2.5% of the total net sales in 2017, representing a decrease of 0.3% as compared to the previous year.

(ii) Resins and plastics

The net sales of resins and plastics amounted to RMB10,218.4 million in 2017, representing an increase of 4.30% as compared to RMB9,797.6 million in 2016. The increase in net sales was mainly attributable to the increase in unit price of resin and plastics, driven by the increase in the costs of raw materials. Due to the lower demand in the downstream market, the sales volume of resins and plastics decreased 5.91% as compared to the previous year, while the weighted average sales price rose by 10.84%. In particular, the weighted average sales price of polyethylene, polypropylene and polyester pellet increased by 11.58%, 7.61% and 15.52%, respectively. Sales of polyethylene, polypropylene and polyester pellet accounted for 32.58%, 33.97% and 19.90% of the total sales of resins and plastics, respectively.

The net sales of resins and plastics accounted for 12.9% of total net sales in 2017, representing a decrease of 2.0% as compared to the previous year.

(iii) Intermediate petrochemicals

The net sales of intermediate petrochemical products amounted to RMB10,070.2 million in 2017, representing an increase of 14.08% as compared to RMB8,827.6 million in 2016. This was mainly due to the increase in unit price of intermediate petrochemical products resulted from the increase in costs of raw materials. The weighted average sales price increased 20.97% as compared to the previous year. The sales volume decreased 5.7% as compared to the previous year due to the decreased downstream demand. The two factors together drove an increase in net sales. Sales of paraxylene, butadiene, ethylene oxide, benzene and glycol accounted for 23.04%, 9.48%, 11.41%, 17.51% and 17.75% of the total sales of intermediate petrochemical products, respectively.

The net sales of intermediate petrochemicals accounted for 12.7% of the total net sales in 2017, representing a decrease of 0.7% as compared to the previous year.

(iv) Petroleum products

The net sales of petroleum products amounted to RMB32,400.6 million in 2017, representing an increase of 34.99% as compared to RMB24,002.6 million in 2016, which was mainly attributable to the increase in prices of refined oil in China driven by the increase in the global crude oil unit price. The weighted average sales price of major products increased by 18.39%, while sales volume increased by 14.02% as compared to the previous year.

The net sales of petroleum products accounted for 40.9% of the total net sales in 2017, representing an increase of 4.5% as compared to the previous year.

40

(v) Trading of petrochemical products

The net sales of the trading of petroleum products amounted to RMB23,697.3 million in 2017, representing an increase of 15.12% as compared to RMB20,585.4 million in 2016.

The net sales of others accounted for 1.1% of our total net sales in 2017, representing a decrease of 0.2% as compared to the previous year.

Cost of sales and operating expenses

Our cost of sales and operating expenses are comprised of cost of sales, selling and administrative expenses, other operating income, other operating expenses and other gains/(losses)-net.

Our cost of sales and operating expenses increased from RMB59,158.6 million in 2016 to RMB72,816.4 million in 2017. Our cost of sales and operating expenses of synthetic fibers, resins and plastics, intermediate petrochemicals, petroleum products, trading of petrochemical products and others were RMB2,480.6 million, RMB8,862.5 million, RMB7,864.1 million, RMB29,280.6 million, RMB23,636.7 million and RMB691.9 million, representing increases of 0.66%, 8.61%, 12.06%, 45.03%, 15.11%, and a decrease of 12.73% as compared to the previous year, respectively as compared to the previous year, respectively. Such increases were primarily due to the increase in cost of raw materials driven by the growth in world crude oil unit price, which substantially increased the cost of sales.

• Cost of sales

Our cost of sales amounted to RMB72,398.3 million in 2017, increased by 23.27% from RMB58,731.7 million in 2016. Cost of sales accounted for 91.39% of net sales for 2017. The increase in cost of sales was primarily due to the increase in crude oil price in 2017.

• Selling and administrative expenses

Our selling and administrative expenses amounted to RMB535.3 million in 2017, representing a decrease of 1.98% as compared to RMB546.1 million in the previous year, mainly due to termination of overhead charge of the riverway from April 2017, resulting in a decrease in administrative expenses.

• Other operating income

Our other operating income amounted to RMB119.0 million in 2017, representing a decrease of 39.69% as compared to RMB197.3 million in the previous year. The significant decrease in other operating income was because the headquarter of the Company did not receive additional refunds of local education fees in Jinshan District, resulting in a decrease of RMB80 million compared with 2016 in government subsidy that was included in other business income.

Net financing income/costs

Our net financing costs were RMB207.3 million in 2017, representing an increase of RMB123.6 million as compared to the net financing costs of RMB83.7 million in the previous year. The increase was mainly due to a significant increase in our bank deposits during 2017, which in turn drove an increase of RMB131.1 million in interest income. In addition, interest expenses increased from RMB53.6 million in 2016 to RMB61.0 million in 2017.

42

Profit before income tax

Our profit before taxation was RMB7,852.9 million in 2017, representing an increase of RMB74.6 million, or 1.0% as compared to the profit before taxation of RMB7,778.3 million in the previous year.

Income tax

Our income tax expenses amounted to RMB1,698.7 million in 2017, representing a decrease of RMB98.1 million as compared to RMB1,796.8 million in the previous year. The decrease was primarily attributable to the tax impact of tax-free investment income generated by us amounted to RMB307.5 million, which increased by RMB81.7million from RMB225.8 million in the previous year. As a result, the income tax payable by the Company for the current period decreased accordingly.

In accordance with the PRC Enterprise Income Tax Law (amended) which took effect from 1 January 2008, the income tax rate of the Company in 2017 was 25% (2016:25%). However, the effective rate for income tax was 21.63% in 2017, compared to 23.10% in 2016. The relatively low effective income tax rate in 2017 was mainly because that share profit of investments accounted for using the equity method amounted to RMB1,243.7 million in 2017, representing an increase of RMB329.6 million as compared to RMB916.8 million in 2016.

Net income

Our net income was RMB6,154.2 million in 2017, representing an increase of RMB172.7 million, or 80.7%, as compared to RMB5,981.5 million in 2016.

B. Liquidity and Capital Resources.

We strive to always have sufficient liquidity to meet our liabilities when due, preparing for both normal and stressed conditions, without incurring unacceptable losses or risking damage to our reputation.

Our primary sources of funding have been cash provided by our operating activities and short term and long term borrowings. Our primary uses of cash have been for cost of sales, other operating expenses and capital expenditures. We prepare monthly cash flow budgets to ensure that we will always have sufficient liquidity to meet our financial obligations as they become due. We arrange and negotiate financing with financial institutions and maintain a certain level of standby credit facilities to reduce liquidity risk. We believe that our current cash on hand, expected cash flows from operations and available standby credit facilities from financial institutions will be sufficient to meet our working capital requirements and repay our short term borrowings and obligations when they become due. In addition, we will continue to optimize our fund raising strategy from short and long term perspectives to take advantage of low interest rates by issuing corporate bonds or debts with low financing costs.

Borrowings and banking facilities

Due to the Company’s net profit position and the reduced capital expenditure, the Company managed to maintain the balance of cash and cash equivalents at a prudent level with a decrease in the amount of borrowings in 2017. Our total borrowings at the end of 2017 amounted to RMB606.2 million, representing an increase of RMB39.8 million as compared to RMB546.4 million at the end of the previous year. We have generally been able to arrange short term loans with several PRC financial institutions as and when needed. The debt obligations as of December 31, 2016 and 2017 were as follows.

	Year Ended December 31,
Debt instruments	2016		2017
	(RMB million)
Short term bank loans (1)		546.4		606.2
Short term loans from a related party (2)		—		—
Long term bank loans (1)		—		—
		546.4		606.2

(1) As of December 31, 2017, no borrowings were secured by the way of property, plant and equipment. We obtained a credit rating of AAA for financing loans, assessed by Shanghai Huajie Credit Rating & Investors Service Co., Ltd., a credit rating agency authorized by the Shanghai Branch of the People’s Bank of China. As of December 31, 2017, the current assets exceeded current liabilities by RMB8,943.8 million. The liquidity of the Company is primarily dependent on the ability to maintain adequate cash inflow from operations, the renewal of its short-term bank loans and on its ability to obtain adequate external financing to support its working capital and meet its debt obligation when they become due. As of December 31, 2017, we had standby credit facilities of RMB21,296.0 million, within which the maturity dates of unused facility amounting to RMB20,273.5 million will be after 31 December 2018. We assessed that all the facilities could be renewed upon their expiration dates. We have carried out a detailed review of the cash flow forecast for the 12 months ending December 31, 2018. Based on such forecast, we believe that we will be able to renew these facilities when they expire based on our well-established relationships with various lenders and adequate sources of liquidity exist to fund our working capital and capital expenditure requirements.

(2) We borrowed short term loans from a subsidiary of Sinopec Group, Sinopec Finance Company Limited, on terms no less favorable to us than terms available from the other commercial banks in China. We have entered into the Comprehensive Services Framework Agreement with Sinopec Group so as to obtain financial services from Sinopec Finance Company Limited for the three years ending December 31, 2017, 2018 and 2019.

Our ability to renew our short term borrowings and obtain additional external financing in the future and the cost of such financing are subject to a variety of uncertainties, including:

• the cost of financing and the condition of financial markets;

• our future operating performance, financial condition and cash flows; and

• potential changes in monetary policy of the Chinese government with respect to bank interest rates and lending practices.

If we fail to rollover, extend or refinance our short term borrowings as necessary in a timely manner, we may be unable to meet our obligations in connection with debt servicing, trade and bills payable and/or other liabilities when they become due. See also Item 3. Key Information – D. Risk Factors—Our development and operation plans have significant capital expenditure and financing requirements, which are subject to a number of risks and uncertainties.

In light of our good credit standing and various financing channels, we believe that we will not experience any difficulty in obtaining sufficient financing for our operations.

We managed to maintain our gearing ratio at a safe level by enhancing controls over both liabilities (including borrowings) and financing risks. We generally do not experience any seasonality in borrowings. However, due to the nature of the capital expenditures plan, long term bank loans can be arranged in advance of expenditures while short term borrowings are used to meet operational needs. The terms of our existing borrowings do not restrict our ability to pay dividends on our shares.

Gearing ratio

As of December 31, 2017, our gearing ratio was 27.71%, while as of December 31, 2016, our gearing ratio was 26.34%. The ratio is calculated using this formula: total liabilities divided by total assets.

48

Capital expenditure

In 2017, our capital expenditure amounted to RMB1,417.0 million, representing an increase of 71.97% as compared to RMB824 million in capital expenditure in 2016. Major projects include the following:

Major Project	Total amount of  project investment RMB million		Amount of  project Investment in 2017 RMB million		Project progress as  of December 31, 2017
Gasoline upgrade project involving an alkylation plant with a capacity of 300,000 tons/year		483		8		Preliminary design
Shanghai Petrochemical’s renovation project involving cogeneration units meeting emission standards		289		174		Under Construction
Shanghai Petrochemical’s project involving third circuit’s incoming power lines with a supply capacity of 220KV		241		113		Under Construction
Renovation project involving low nitrogen combustion in olefin cracking furnace No. 2		121		80		Under Construction
Thermoelectric Department’s rectification project involving an airtight fuel storage yard		100		76		Under Construction
Thermoelectric Department’s renovation project involving furnaces Nos. 3 and 4 meeting emission standards		99		30		Under Construction

Our capital expenditure for 2018 is estimated at approximately RMB1.2 billion.

Proposed Dividend Distribution

A dividend for the year ended December 31, 2017 of RMB0.3 per share (including tax), based on 10,823,813,500 shares outstanding, amounted to a total dividend of RMB3,247,144,000, was proposed by the Board of Directors on March 20, 2018. The proposal remains to be approved at our 2017 Annual General Meeting.

C. Research and Development, Patents and Licenses, etc.

We have a number of technology development units, including the Petrochemical Research Institute, the Plastics Research Institute, the Polyester Fiber Research Institute, the Acrylic Fiber Research Institute and the Environmental Protection Research Institute. These units are charged with various research and development tasks with respect to new technology, new products, new production processes and equipment and environmental protection. Our research and development expenditures in 2015, 2016 and 2017 were RMB87.6 million, RMB102.1 million and RMB36.7 million, respectively. The decrease in research and development expenditures in 2017 was mainly due to the completion of a research and development project on carbon fiber in the first half of 2017.

We are not, in any material aspect, dependent on any patents, licenses, industrial, commercial or financial contracts, or new production processes.

D. Trend Information

In 2018, the world economy is expected to continue its recovery momentum, but the contributions from the conventional industries to economic growth would weaken and the effect of commodity price rises would subside as well. With the economic recovery, the pace of normalization of monetary policies in various countries around the world is expected to be accelerated and the risk resistance capability of the financial markets would be further strengthened. In particular, the implementation of the tax reform policy in the US would compel other countries to cut taxes. This will reduce the burden on enterprises, enhance the vitality of enterprises and boost global economic growth. It is estimated that developed economies would see growth accelerating generally, while emerging and developing economies would remain as the major force behind world economic growth in 2018.

China’s economy has shifted from a phase of speedy growth to a phase of high-quality development. Its economic growth is now at a critical period of transforming development model, optimizing economic structure and changing growth momentum. In 2018, China is expected to continue to maintain the general keynote of work which is to make progress while ensuring stability; continue with the supply-side structural reform as the main direction; and make overall plans for carrying out various tasks to maintain growth, boost reforms, readjust the structure, improve people’s livelihood and prevent risks. China’s economy is anticipated to remain stable with good development momentum.

In 2018, oil demand is expected to further grow as the world economy continues to recover, while OPEC is expected to continue to implement the agreement to limit production. However, the rebound in oil prices is expected to stimulate further rise of U.S. crude oil output, thus impeding the rise of oil prices. Moreover, the trend of the U.S. dollar and the geopolitical situation would continue to impact the oil price trend to a certain extent. The petroleum market is anticipated to be able to strike a balance between supply and demand in 2018, while the average crude oil price is expected to go up further.

As the escalating global economy is expected to fuel an increasing demand for petrochemical products, the global petrochemical industry is expected to remain stable with a rise trend in 2018. Since the supply-side reform is proceeding and the growth in downstream demand remains stable in China, the petrochemical industry is expected to continue to see structural improvement to the supply and demand. However, since there is no fundamental change in the imbalance between the supply-side structural surplus and the structural shortage in the domestic refined oil market and petrochemicals market, the expansion of the scale of domestic large private refining and petrochemical enterprises and the recovery of coal chemical production capacity would further intensify market competition in the future. China’s “Belt and Road” initiative and Sinopec’s plan for the construction of a petrochemical industrial base in Shanghai would also bring about a new round of development opportunities for the Company.

E. Off-balance Sheet Arrangements

As of December 31, 2017, we had no contingent liabilities in respect of guarantees issued to banks in favor of our associated companies and other unlisted investments (December 31, 2016: nil). Other than our capital commitments disclosed in Note 32 in our consolidated financial statements included in Item 18. Financial Statements, we do not have any other off-balance sheet arrangements.

D. Employees.

As of December 31, 2017, we had 10,361 employees.

The following table shows the approximate number of employees we had at the end of the last three years by the principal business function they performed:

Approximately 52.49% of our work force are graduates with a tertiary degree or higher. In addition, we offer our employees opportunities for education and training based upon our development plans and requirements and the individual performance of each employee.

61

A system of labor contracts has been adopted in our Company. The contract system imposes discipline, provides incentives to adopt better work habits and gives us greater management control over our work force. We believe that by linking remuneration to productivity, the contract system has also improved employee morale. As of December 31, 2017, almost all of the work force was employed pursuant to labor contracts which specify the employee’s position, responsibilities, remuneration and grounds for termination. The contracts generally have short terms of one to five years and may be renewed with the agreement of both parties. The remaining personnel are employed for an indefinite term.

We have a labor union that protects employees’ rights, aims to assist in the fulfillment of our economic objectives, encourages employee participation in management decisions and assists in mediating disputes between us and union members. We have not been subject to any strikes or other labor disturbances which have interfered with our operations, and we believe that our relations with our employees are good.

Total remuneration of our employees includes salary and bonuses. Employees also receive certain benefits in terms of housing, education and health services that we subsidize, and other miscellaneous subsidies. In 2017, we incurred RMB2,462.2 million in employment costs.

In compliance with Shanghai regulations, we and our employees participate in a defined contribution government pension scheme under which all employees upon retirement are entitled to receive pensions. In order to safeguard and properly enhance the living level of retired employees and improve the medium and long term incentive system, the company established an enterprise annuity plan. According to the plan, to the extent that the employees volunteer for the related payments and have been with the Company for one year or more, such employees are entitled to participate in the enterprise annuity plan. We will make payments to match the payments made by the employees after giving considerations to our profitability, the employee’s work responsibilities, contributions, and treatments post retirement based on the principle of universal benefits. We have 17,854 retired employees under the above retirement insurance plans.

In addition to the pension benefits, pursuant to the relevant laws and regulations of the PRC, we and our employees participate in defined social security contributions for employees, such as a housing fund, basic medical insurance, supplementary medical insurance, unemployment insurance, injury insurance and maternity insurance.

Share Option Incentive Scheme

We adopted a share option incentive scheme on December 23, 2014, pursuant to which our directors, senior management members and key business personnel may be granted options to purchase our A shares. Under the share option incentive scheme, the total number of underlying shares to be granted shall neither exceed 10% of the total share capital of the Company nor exceed 10% of the total A-share capital of the Company.

The exercisable period for the share options shall be three years, commencing from the expiry of the two-year period after the grant date, and the vesting period for each grant under the scheme shall be no less than two years. The exercise price of a share under initial grant will be determined by our Board of Directors at its discretion, which shall not be lower than the highest of: (1) the closing price of the A shares of the Company on the trading day immediately before the date of announcement on the summary of the draft scheme, which was RMB3.29 per share; (2) the average closing price of the A shares of the Company for the 30 trading days immediately before the date of announcement on the summary of the draft scheme, which was RMB3.27 per share; and (3) RMB4.20 per share.

B. Related Party Transactions.

Intercompany service agreements and business-related dealings

During 2016, pursuant to the Mutual Product Supply and Sales Service Framework Agreement entered into by the Company and Sinopec Corp., we purchased raw materials from, and sold petroleum products and petrochemicals as well as leased properties to, Sinopec Corp. and its associates, and Sinopec Corp. and its associates acted as sales agents for our petrochemical products. Under the Comprehensive Services Framework Agreement entered into by the Company and Sinopec Group, we accepted construction and installation, engineering design, insurance agency and financial services relating to the petrochemical industry provided by Sinopec Group and its associates. The relevant connected transactions were conducted in accordance with the terms of the Mutual Product Supply and Sales Services Framework Agreement and the Comprehensive Services Framework Agreement. The current Mutual Product Supply and Sales Service Framework Agreement and Comprehensive Services Framework Agreement were renewed with Sinopec Corp. and Sinopec Group respectively upon approval and authorization at our 2016 Extraordinary General Meeting held on October 18, 2016. At the 2016 Extraordinary General Meeting, our shareholders also approved certain caps on the annual transaction values of certain ongoing continuing connected transactions for the years ending December 31, 2017, 2018 and 2019. The transaction amounts of the relevant connected transactions in 2017 did not exceed such caps.

The purchases by us of crude oil and related materials from, and sales of petroleum products by us to, Sinopec Corp. and its associates were conducted in accordance with the State’s relevant policy and applicable State tariffs or State guidance prices. As long as the State does not lift its control over purchases of crude oil, sales of petroleum products and pricing thereof, such connected transactions will continue to occur. We sell petrochemicals to Sinopec Corp. and its associates and Sinopec Corp. and its associates act as agents for the sales of petrochemicals in order to reduce our inventories, expand their trading, distribution and sales networks and improve our bargaining power with our customers. We lease part of the properties to Sinopec Corp. and its associates in consideration of their good financial background and credit standing. We accept construction and installation, engineering design, insurance agency and financial services relating to the petrochemical industry from Sinopec Group and its associates in order to secure steady and reliable services at reasonable prices.

The prices of the continuing connected (i.e., related-party) transactions conducted between the Company and Sinopec Group, Sinopec Corp. and its associates are determined by the parties involved after consultation pursuant to (1) the fixed price of the state; or (2) the guiding price of the state; or (3) market prices, and the conclusion of agreements for the connected transactions are in compliance with the needs of the Company’s production and operation. Therefore the above continuing connected transactions do not cause a material impact on the Company’s independence.

66

The table below sets forth certain relevant information regarding our continuing connected transactions with Sinopec Corp. and Sinopec Group under the Mutual Product Supply and Sales Services Framework Agreement and the Comprehensive Services Framework Agreement in 2017.

On December 5, 2016, the Company entered into an asset leasing agreement (the “Lease Agreement”) with Baishawan branch of Sinopec Petroleum Reserve Company Limited (the “Baishawan Branch”), a wholly-owned subsidiary of Sinopec Group. Pursuant to the Lease Agreement, the Company rents the oil tanks and ancillary facilities from the Baishawan Branch at an annual rent up to RMB53,960,000 (exclusive of VAT), with the leasing period from 1 January 2016 to 31 December 2018. The Lease Agreement was considered and approved at the 16th meeting of the eighth session of the Board on 24 November 2016. In 2017, the Company incurred leasing cost of RMB53,960,000.

On April 27, 2017, the Company considered and approved at the 19th meeting of the Eighth Session of the Board to give up its pre-emptive rights in acquiring the 50% equity interests in SECCO held by BP. Sinopec Corp. intended to acquire the above equity interests through its subsidiary, Sinopec Shanghai Gaoqiao Petrochemical Co., Ltd..

Equity joint venture

Late in 2001, we established SECCO, a Sino-foreign equity joint venture, together with BP and Sinopec Corp. We own 20% interest in SECCO, while BP and Sinopec Corp. own 50% and 30% interests in SECCO, respectively. SECCO was established to build and operate a 900,000 ton Rated Capacity ethylene petrochemical manufacturing facility to manufacture and market ethylene, polyethylene, styrene, polystyrene, propylene, acrylonitrile, polypropylene, butadiene, aromatics and by-products; provide related after-sales services and technical advice with respect to such petrochemical products and by products; and engage in polymers application development. SECCO completed construction in 2005. SECCO’s total initial registered capital was U.S.$901,440,964, of which we provided the Renminbi equivalent of U.S.$180,287,952.

67

To fund SECCO’s new acrylonitrile plant project with a capacity of 260,000 tons/year, its new ethylene plant with a new supercharger, its new butadiene plant with a capacity of 90,000 tons/year, and its utility facilities upgrading project, in 2013, the shareholders of SECCO agreed to increase the registered capital of SECCO by U.S.$150,085,618 according to their respective shares in the equity interests in SECCO.

In October 2017, BP transferred its 50% equity interests in SECCO to a subsidiary of Sinopec Corp., Sinopec Shanghai Gaoqiao Petrochemical Co., Ltd.. As a result of equity transfer, we, Sinopec Corp. and Sinopec Shanghai Gaoqiao Petrochemical Co., Ltd. own 20%, 30% and 50% interests in SECCO, respectively, and SECCO was converted into a PRC domestic company. The registered capital of SECCO is RMB7,800,811,272.00, all of which had been fully contributed by the shareholders in accordance with their equity percentages in SECCO as of October 18, 2017..

HKSE connected transactions rules

We are required by HKSE listing rules to obtain advance shareholder approval for certain transactions with related parties such as Sinopec Group, Sinopec Corp., or its associates. We comply with such HKSE listing rules by obtaining advance shareholder approval at least every three years for the renewal of our framework agreements (e.g., the Mutual Product Supply and Sales Services Framework Agreement and the Comprehensive Services Framework Agreement) with Sinopec Corp. and Sinopec Group for setting maximum aggregated annual values spent on the supply of products and services under these agreements. The independent non-executive directors will need to confirm each year, upon reviewing our continuing connected transaction, that these transactions are conducted in the ordinary and usual course of our business, on normal commercial terms and in accordance with the terms of these agreements.

We are not aware of any litigation or arbitration proceedings in which any of our directors, any member of our senior management or any of our affiliates is an adverse party or has a material adverse interest.

Dividend Policy

Our Board of Directors may propose dividend distributions subject to the approval of the shareholders. The Articles of Association also provide that, the aggregate profits distributed in cash in the recent three years shall not be less than 30% of the average annual distributable profits within such three-year period.

The Articles of Association require that cash dividends and other distributions in respect of H shares be declared in Renminbi and paid by us in Hong Kong dollars while cash dividends and other distributions in respect of our domestic shares be paid in Renminbi. If we record no profit for the year, we may not distribute dividends in such year.

We expect to continue to pay dividends, although there can be no assurance as to the particular amounts that might be paid from year to year. Payment of future dividends will depend upon our revenue, financial condition, future earnings and other factors. See Item 5. Operating and Financial Review and Prospects and Item 3.

B. Memorandum and Articles of Association.

We are a joint stock limited company established in accordance with the PRC Company Law and certain other laws and regulations of the PRC. We are registered with the Shanghai Administration of Industry and Commerce with business license number 91310000132212291W.

The following is a summary based upon provisions of our Articles of Association as currently in effect, the PRC Company Law (1993) (as amended) and other selected laws and regulations applicable to us. You should refer to the text of the Articles of Association and to the texts of applicable laws and regulations for further information.

Our Articles of Association provide, at article 12, that our purpose is:

• to build and operate a diversified industrial company which will be one of the world’s leading petrochemical companies;

• to promote the development of the petrochemical industry in China through the production of a broad variety of outstanding products; and

• to practice advanced, scientific management and apply flexible business principles, and to develop overseas markets for our products so that we and our shareholders receive reasonable economic benefits.

Our scope of business is limited to matters approved by Chinese authorities. Article 13 provides that our primary business scope includes:

Refining crude oil, petroleum products, petrochemical products, synthetic fibers and monomers, plastic products, raw materials for knitting and textile products, preparation of catalysts and recover waste catalysts, power, heat, water and gas supply, water treatment, railway cargo loading and unloading, inland water transport, wharf operation, warehousing, design, research and development, technology development, transfer, consultancy and other services, property management, lease of self-owned premises, internal staff training, design and fabrication of various advertisements, release of advertisements on self-owned media and quality technology services (administrative license should be obtained when required). We may adjust these subject to approval by governmental authorities.

The following discussion primarily concerns our shares and the rights of our shareholders. Holders of our ADSs will not be treated as our shareholders and will be required to surrender their ADSs for cancellation and withdrawal from the depositary facility in which the H shares are held in order to exercise shareholder rights in respect of H shares.

Domestic shares and overseas-listed foreign invested H shares are both ordinary shares in our share capital. Domestic shares are shares we issue to domestic Chinese investors for subscription in Renminbi, while H shares are shares we issue for subscription in other currencies to investors from Hong Kong, Macau, Taiwan and outside of China.

Sources of Shareholders’ Rights

China’s legal system is based on written statutes and is a system in which decided legal cases have little precedent value. China’s legal system is similar to civil law systems in this regard. In 1979, China began the process of developing its legal system by undertaking to promulgate a comprehensive system of laws. In December 1993, the Standing Committee of the 8th National People’s Congress adopted the PRC Company Law. Although the PRC Company Law is expected to serve as the core of a body of regulatory measures, which will impose a uniform standard of corporate behavior on companies and their directors and shareholders, only a limited portion of this body of regulatory measures has so far been promulgated.

Currently, the primary sources of shareholder rights are the Articles of Association, the PRC Company Law and the HKSE listing rules, which, among other things, impose standards of conduct, fairness and disclosure on us, our directors and our controlling shareholder. To facilitate the offering and listing of shares of Chinese companies overseas, and to regulate the behavior of companies whose shares are listed overseas, the former State Council Securities Committee and the former State Commission for Restructuring the Economic System issued the Mandatory Provisions for articles of association of Companies Listing Overseas on August 27, 1994. These provisions have been incorporated into our Articles of Association and any amendment to those provisions will only become effective after approval by the companies approval department authorized by the State.

In addition, upon the listing of and for so long as the H shares are listed on the HKSE, we will be subject to those relevant ordinances, rules and regulations applicable to companies listed on the HKSE, the Securities and Futures Ordinance and the Codes on Takeovers and Mergers and Share Repurchases.

Unless otherwise specified, all rights, obligations and protections discussed below derive from our Articles of Association and/or the PRC Company Law.

71

Enforceability of Shareholders’ Rights

There has not been any public disclosure in relation to the enforcement by holders of H shares of their rights under the charter documents of joint stock limited companies or the PRC Company Law or in the application or interpretation of the Chinese or Hong Kong regulatory provisions applicable to Chinese joint stock limited companies.

In most states of the United States, shareholders may sue a corporation “derivatively.” A derivative suit involves the commencement by a shareholder of a corporate cause of action against persons who have allegedly wronged the corporation, where the corporation itself has failed to enforce the claims directly. This would include suits against corporate officers, directors, or the controlling shareholder. This type of action is brought based upon a primary right of the corporation, but is asserted by a shareholder on behalf of the corporation. In accordance with the PRC Company Law, if a company incurs losses due to the violation of any provision of laws, administrative regulations or the company’s articles of association by any of its directors, supervisors and officers during his/her discharge of duties entrusted by the company, or due to any other person’s infringement of the company’s legal rights or interests, the shareholders of the company may take legal action before a court under the PRC Company Law.

Our Articles of Association provide that all differences or claims

• between a holder of H shares and us;

• between a holder of H shares and any of our directors, supervisors, manager or other senior officers; or

• between a holder of H shares and a holder of domestic shares,

involving any right or obligation provided in the Articles of Association, the PRC Company Law or any other relevant law or administrative regulation which concerns our affairs must, with certain exceptions, be referred to arbitration at either the China International Economic and Trade Arbitration Commission in China or the Hong Kong International Arbitration Center. Our Articles of Association also provide that the arbitration will be final and conclusive. On June 21, 1999, an arrangement was made between Hong Kong and China for the summary mutual enforcement of each other’s arbitration awards in a manner consistent with the United Nations Convention on the Recognition and Enforcement of Foreign Arbitral Awards and practices that occurred before the handover of Hong Kong to China. This arrangement was approved by the Supreme Court of China and the Hong Kong Legislative Council, and became effective on February 1, 2000.

All of our directors and officers reside outside the United States (principally in China) and substantially all of our assets and of those persons are located outside the United States. Therefore, you may not be able to effect service of process within the United States against any of those persons. In addition, China does not have treaties providing for the reciprocal recognition and enforcement of judgments of courts within the United States or most other countries that are members of the Organization for Economic Cooperation and Development. This means that administrative actions brought by regulatory authorities such as the Securities and Exchange Commission, and other actions which result in foreign court judgments could only be enforced in China if the judgments or rulings do not violate the basic principles of the law of China or the sovereignty, security and social public interest of the society of China, as determined by a People’s Court of China which has jurisdiction for recognition and enforcement of judgments. We have been advised by our Chinese counsel, Haiwen & Partners, that there is doubt as to the enforceability in China of any actions to enforce judgments of United States courts arising out of or based on the ownership of our H shares or ADSs, including judgments arising out of or based on the civil liability provisions of United States federal or state securities laws.

Restrictions on Transferability and the Share Register

All fully paid up H shares will be freely transferable in accordance with the Articles of Association unless otherwise prescribed by law and/or administrative regulations. Under current laws and regulations, H shares may be traded only among investors who are not Chinese persons, and may not be sold to Chinese investors. Consequences under Chinese law of a purported transfer of H shares to Chinese investors are unclear.

As provided in our Articles of Association, we may refuse to register a transfer of H shares without providing any reason unless:

• all relevant transfer fees and stamp duties are paid;

• the instrument of transfer is accompanied by the share certificates to which it relates and any other evidence reasonably required by our board to prove the transferor’s right to make the transfer;

• there are no more than four joint holders as transferees; and

• the H shares are free from any lien of ours.

Additionally, no transfers of shares may be registered within the 30 days prior to a shareholders’ general meeting or within five days before we decide on the distribution of dividends.

72

We are required to keep a register of our shareholders which shall be comprised of various parts, including one part which is to be maintained in Hong Kong in relation to H shares listed on the HKSE. Shareholders have the right to inspect the share register. For a reasonable fee, shareholders may copy any part of the share register, obtain background information regarding our directors, supervisors, manager and other senior officers, minutes of shareholder general meetings and reports regarding our share capital and any share repurchases in the prior year.

Dividends

Upon approval by ordinary resolution at a shareholders’ meeting, our Board of Directors may propose dividend distribution at any time. The Articles of Association permits dividends issued in the form of cash or shares. Special resolution of the shareholders’ general meeting is required for dividends issued in the form of shares.

Dividends may only be distributed, however, after allowance has been made for:

• recovery of losses, if any;

• allocations to the statutory common reserve fund; and

• allocations to a discretionary common reserve fund.

The Articles of Association require us to appoint on behalf of the holders of H shares a receiving agent which is registered as a trust corporation under the Trustee Ordinance of Hong Kong to receive dividends we declare in respect of the H shares on behalf of the H shareholders. The Articles of Association require that cash dividends and other distributions in respect of H shares be declared in Renminbi and paid by us in Hong Kong dollars while cash dividends and other distributions of the domestic shares shall be paid in Renminbi.

If we record no profit for the year, we may not normally distribute dividends for the year.

Dividend payments may be subject to Chinese withholding tax. See Item 10. Additional Information – E. Taxation.

Voting Rights and Shareholders’ Meetings

Our Board of Directors must convene a shareholders’ annual general meeting once every year within six months from the end of the preceding financial year. Our board must convene an extraordinary general meeting within two months of the occurrence of any one of the following events:

• where the number of directors is less than five as required by the PRC Company Law or two-thirds of the number specified in our Articles of Association;

• where our unrecovered losses reach one-third of the total amount of our share capital;

• where shareholder(s) holding 10% or more of our issued and outstanding voting shares request(s) in writing; or

• whenever our board deems necessary or our Supervisory Committee so requests.

Meetings of a special class of shareholders must be called in specified situations when the rights of the holders of that class of shares may be varied or abrogated, as discussed below. The Board of Directors, the Supervisory Committee, and shareholders individually or collectively holding 3% or more of our total voting shares are entitled to make written proposals to a shareholders’ meeting. Shareholders individually or collectively holding more than 3% of our total shares may submit written interim proposals to the convener of a shareholders’ meeting ten days before the meeting.

All shareholders’ meetings must be convened by our board by notice given to shareholders by personal service, mail or announcement in the newspaper not less than 45 days before the meeting. Based on the written replies we receive 20 days before a shareholders’ meeting, we will calculate the number of voting shares represented by shareholders who have indicated that they intend to attend the meeting. We can convene the shareholders’ general meeting if the number of voting shares represented by those shareholders is more than one-half of our total voting shares. Otherwise, we shall, within five days, inform the shareholders again of the motions to be considered and the date and venue of the meeting by way of public announcement. After the announcement is made, the shareholders’ meeting may be convened. Our accidental omission to give notice of a meeting to, or the non-receipt of notice of a meeting by, a shareholder will not invalidate the proceedings at that shareholders’ meeting. However, an extraordinary shareholders meeting cannot conduct any business not contained in the notice of meeting.

Shareholders at meetings have the power, among other things, to decide on our operational policies and investment plans, to approve or reject our proposed annual budget, approve our profit distribution plans, an increase or decrease in share capital, the issuance of debentures, our merger or liquidation and any amendment to our Articles of Association. Shareholders also have the right to review any proposals by a shareholder owning 3% or more of our shares.

73

In general, holders of H shares and domestic shares vote together as a single class at all meetings and on all matters. However, the rights of a class of shareholders may not be varied or abrogated, unless approved by both a special resolution of all shareholders at a general shareholders’ meeting and by a special resolution of shareholders of that class of shares at a separate meeting. Our Articles of Association specify, without limitation, that the following amendments would be deemed to be a variation or abrogation of the rights of a class of shareholders:

• increasing or decreasing the number of shares of a class or of a class having voting or distribution rights or privileges equal or superior to that class;

• removing or reducing rights to receive dividends in a particular currency;

• creating shares with voting or distribution rights superior to shares of that class;

• restricting or adding restrictions to the transfer of ownership of shares of that class;

• allotting and issuing rights to subscribe for, or to convert into, shares of that class or another class;

• increasing the rights or privileges of any other class; or

• modifying the provision of our Articles of Association that specifies which amendments would be deemed a variation or abrogation of the rights of a class of shareholder.

For votes on any of these matters, or any other matter that would vary or abrogate the rights of the domestic shares or H shares, the holders of domestic shares and H shares are deemed to be separate classes and vote separately. However, “Interested Shareholders” are not entitled to vote at class meetings. The meaning of “Interested Shareholder” depends on the proposal to be voted on at the class meeting:

• If the proposal is for us to repurchase our shares either from all shareholders proportionately or by purchasing share on a stock exchange, an “Interested Shareholder” is our controlling shareholder;

• If the proposal is for us to repurchase our shares from a shareholder by a private contract, an “Interested Shareholder” is the shareholder whose shares would be repurchased;

• If the proposal is for our restructuring, an “Interested Shareholder” is any shareholder that has an interest in the restructuring different from the other shareholders of the class or who bears a burden under the proposed restructuring that is less than proportionate to his shareholdings of the class.

Our Articles of Association specifically provide that an issue of up to 20% of domestic and H shares would not be a variation or abrogation of the rights of domestic shareholders or H shareholders, therefore, separate approval of the domestic shareholders or H Shareholders would not be required.

Each share is entitled to one vote on all matters submitted to a vote of our shareholders at all shareholders’ meetings, except for meetings of a special class of shareholders where only holders of shares of the affected class are entitled to vote on the basis of one vote per share of the affected class.

Shareholders are entitled to attend and vote at meetings either in person or by proxy. Proxy authorization forms must be in writing and deposited at our company’s principal offices, or at such other place specified in the notice of shareholders meeting not less than 24 hours before the time that such meeting will be held or the time appointed for passing upon the relevant resolutions. If a proxy authorization form is signed by a third party on behalf of the relevant shareholder, then such proxy authorization form must be accompanied by the signature authorization letter or other such document authorizing such third party to sign on behalf of the shareholder.

Except for those actions discussed below, which require supermajority votes, or special resolutions, resolutions of the shareholders are passed by a simple majority of the voting shares held by shareholders who are present in person or by proxy. Special resolutions must be passed by more than two-thirds of the voting rights represented by shareholders who are present in person or by proxy.

The following decisions must be adopted by special resolution:

• an increase or reduction of our share capital or the issue of shares of any class, warrants and other similar securities;

• the issue of our debentures;

• our division, merger, dissolution and liquidation;

• amendments to our Articles of Association;

• significant acquisition or disposal of material assets or provision of guarantees conducted within the period of one year with a value exceeding 30% of our latest audited total assets;

• share incentive schemes; and

74

• any other matters considered by the shareholders in a general meeting and which they have resolved by way of an ordinary resolution to be material and should be adopted by special resolution.

All other actions taken by the shareholders, including the appointment and removal of our directors and independent auditors and the declaration of normal dividend payments, will be decided by an ordinary resolution of the shareholders.

Our listing agreement with the HKSE provides that we may not permit amendments to certain sections of our Articles of Association that are subject to the Mandatory Provisions. These sections include provisions relating to (i) varying the rights of existing classes of shares, (ii) voting rights, (iii) our ability to purchase our own shares, (iv) rights of minority shareholders and (v) procedures on liquidation. In addition, certain amendments to the Articles of Association require the approval and assent of Chinese authorities.

Board of Directors

Our Articles of Association authorize up to 12 directors. Directors are elected by shareholders at a general meeting for a three year term from among candidates nominated by the Board of Directors or by shareholders holding 3% or more of our shares (Independent Directors may be nominated by shareholders each holding 1% or more of our shares). Because our directors do not serve staggered terms, the entire Board of Directors will stand for election, and could be replaced, every three years. Our directors are not required to hold any shares in us, and there is no age limit requirement for the retirement or non- retirement of our directors.

In addition to obligations imposed by laws, administrative regulations or the listing rules of the stock exchanges on which our shares are listed, the Articles of Association place on each of our directors, supervisors, manager and any other senior officers a duty to each shareholder, in the exercise of our functions and powers entrusted to them:

• not to cause us to exceed the scope of business stipulated in our business license;

• to act honestly in what he considers our best interests;

• not to expropriate our assets in any way, including (without limitation) usurpation of opportunities which may benefit us; and

• not to expropriate the individual rights of shareholders, including (without limitation) rights to distributions and voting rights, except according to a restructuring which has been submitted to the shareholders for their approval in accordance with the Articles of Association.

Our Articles of Association further place on each of our directors, supervisors, manager and other senior officers:

• a duty, in the exercise of their powers and discharge of their duties, to exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances;

• a fiduciary obligation, in the discharge of his duties, not to place himself or herself in a position where his or her interests may conflict with his or her duty to us; and

• a duty not to cause a person or an organization related or connected to him or her in specified relationships to do what they are prohibited from doing.

We pay all expenses that our directors incur for their services as directors. Directors also receive compensation for their services under service contracts that are negotiated by the Board of Directors and approved by the shareholders.

Subject to the stipulations of relevant laws and regulations, the shareholders in a general meeting may by ordinary resolution remove any director before the expiration of his term of office. Except for the restrictions placed on the controlling shareholder, discussed below, our shareholders in general meeting have the power to relieve a director or supervisor from liability for specific breaches of duty.

Cumulative voting is required for a meeting of shareholders held for the election of two or more of our directors or supervisors as long as more than 30% of our outstanding shares are held by a single shareholder. Cumulative voting allows shareholders to cast a number of votes for a candidate equal to the number of shares held multiplied by the number of directors being elected at the shareholders’ meeting. If a shareholder attempts to cast more votes than he is entitled to under this system, all of the shareholder’s votes will be invalid and will be deemed an abstention.

More than one third of our directors of board must be independent from our shareholders and not hold any office with us (each, “Independent Director”). At least one Independent Director must be an accounting professional and all Independent Directors must possess a basic knowledge of the operations of a listed company and be familiar with relevant laws and rules and have at least five years working experience in law, economics or other area required for the fulfillment of responsibilities as an Independent Director. Independent Directors may not serve for terms exceeding six years. In addition, there are specific persons who are disqualified from acting as Independent Director. These include:

75

• immediate family members of persons who work for us or our associated entities;

• persons or their immediate family who hold one percent or more of our shares or are among our ten largest shareholders;

• any persons that satisfied the foregoing conditions within the past one year;

• persons providing financial, legal, consultation or other services to us or our associated entities;

• persons who already serve as Independent Director for five other listed companies; and

• anyone identified by the CSRC as unsuitable for serving as an Independent Director.

If the resignation of an Independent Director would cause our Board of Directors to have less than one third Independent Directors, the resignation will only become effective after a new Independent Director has been appointed.

Our Board will be required to meet at least four times each year. Directors who miss two consecutive Board meetings without appointing an alternate director to attend on their behalf will be proposed for removal at the next shareholders’ meeting, provided that Independent Directors may miss three consecutive meetings in person before being proposed for removal.

Directors may not vote on any matter in which he has a material interest, nor will he be counted for purposes of forming a quorum on such a matter.

Board resolutions are passed by a simple majority of the Directors except for the following matters which require the consent of more than two thirds of the Directors:

• proposals for our financial policies;

• the increase or reduction of our registered capital;

• the issue of securities of any kind and their listing;

• any repurchase of our shares;

• significant acquisitions or disposals;

• our merger, division or dissolution; and

• any amendment to our Articles of Association.

Our Board of Directors or Supervisory Committee may nominate candidates for our Board of Directors and Supervisory Committee. In addition, shareholders holding one percent or more of our shares have the right to nominate candidates for Independent Director or Independent Supervisor and shareholders holding three percent or more of our shares have the right to nominate other candidates for Director or Supervisor. For candidates for Director, the nominator and candidates will be responsible for providing truthful and complete information about the candidate for disclosure. Candidates for Independent Director must publicly declare that there does not exist any relationship between himself and us that may influence his independent, objective judgment. The CSRC may veto any candidate for Independent Director.

Any material connected transactions are subject to prior approval by our Independent Directors. Connected transactions are those defined by the HKSE and by Chinese rules and regulations, but would generally include transactions with any of the following:

• any company that, directly or indirectly, controls us or is under common control with us;

• any shareholders owning 5% or more of our shares;

• our directors, supervisors and other senior management;

• any of our key technical personnel or key technology suppliers; and

• any close relative or associate of any of the above.

Our Independent Directors can also propose to the Board of Directors the appointment or removal of our auditors, the convening of a Board meeting, independently appoint external auditors, solicit votes from shareholders and report circumstances directly to shareholders, Chinese securities regulatory authorities or other government departments. Two or more may request that the Board convene an extraordinary meeting of shareholders.

Our Independent Directors will have to express their opinion on specified matters to the Board or to the shareholders at a shareholders’ meeting, either by a single unanimous statement or individually. These matters are:

• the nomination, removal and remuneration of directors or senior management;

• any major loans or financial transactions with our shareholders or related enterprises and whether we have taken adequate steps to ensure repayment;

76

• matters that the Independent Director believes may harm the rights and interests of minority shareholders; and

• any other matter that they are required to opine on by applicable law or rules.

These opinions must be expressed as either, agree, qualified agreement, opposition or unable to form an opinion. All but agreement must also be accompanied by a supporting explanation. If public disclosure of the matter is required, we must also disclose the opinions of our Independent Directors.

Any Independent Director may engage independent institutions to provide independent opinions as the basis of their decision. We must arrange the engagement and bear any costs.

Supervisory Committee

The Supervisory Committee is responsible for supervising our directors and senior officers and preventing them from abusing their positions and powers or infringing upon the rights and interests of our company or those of our shareholders and employees. The Supervisory Committee has no power over the decisions or actions of our directors or officers except for requesting the directors or officers to correct any acts that are harmful to our interests. The Supervisory Committee is composed of seven members appointed for a three year term. It has the right to:

• attend the meetings of our Board of Directors;

• inspect our financial affairs;

• supervise and evaluate the conduct of our directors, general manager and other senior officers in order to determine whether they violate any laws, regulations or the Articles of Association in performing their duties;

• require our directors, general manager or other senior officers to correct any act harmful to our interests and those of our shareholders and employees;

• verify financial reports, accounting reports, business reports, profit distribution plans and other financial information proposed to be tabled at the shareholders’ general meeting, and entrust registered accountants and practicing accountants to re-review such documents upon its discovery of any problems;

• require the Board of Directors to convene an extraordinary general meeting of shareholders;

• represent us in negotiations with directors or in initiating legal proceedings against a director on our company’s behalf;

• conduct investigation into any identified irregularities in our operations, and where necessary, to engage accountants, legal advisers or other professionals to assist in the investigation; and

• any other matters authorized by the Articles of Association.

One third of our Supervisory Committee members must be employee representatives appointed by our employees. The remaining members are appointed by the shareholders in a general meeting, provided that our directors, general manager and senior officers are not eligible to serve as supervisors. The Supervisory Committee must meet at least four times a year. Decisions of the Supervisory Committee can be passed by the consents of over two thirds of all the supervisors. We will pay all reasonable expenses incurred by the Supervisory Committee in appointing professional advisors, such as lawyers, accountants or auditors.

Liquidation Rights

In the event of our liquidation, payment of borrowings out of our remaining assets will be made in the order of priority prescribed by applicable laws and regulations. After payment of borrowings, we will distribute the remaining property to shareholders according to the class and proportion of their shareholdings. For this purpose, the H shares will rank equally with the domestic shares.

Obligation of Shareholders

Shareholders are not obligated to make any further contributions to our share capital other than as agreed by the subscriber of the relevant shares on subscription. This provision means that holders of ADSs will also not be obligated to make further contributions to our share capital.

Duration

We are organized as a stock limited company of indefinite duration.

Increase in Share Capital

The Articles of Association require that approval by a resolution of the shareholders be obtained prior to issuing new shares. New issues of shares must also be approved by the relevant Chinese authorities.

77

Reduction of Share Capital and Purchase by Us of Our Shares

We may reduce our registered share capital only upon obtaining the approval of the shareholders and, when applicable, relevant Chinese authorities. Repurchases may be made either by way of a general offer to all shareholders in proportion to their shareholdings, by purchasing our shares on a stock exchange or by an off-market contract with shareholders.

Restrictions on Large or Controlling Shareholders

Our Articles of Association provide that, in addition to any obligation imposed by laws and administrative regulations or required by the listing rules of the stock exchanges on which our shares are listed, a controlling shareholder cannot exercise voting rights in a manner prejudicial to the interests of the shareholders generally or of some part of the shareholders:

• to relieve a director or supervisor from his or her duty to act honestly in our best interest;

• to approve the expropriation by a director or supervisor (for his or her own benefit or for the benefit of another person) of our assets in any way, including, without limitation, opportunities which may benefit us; or

• to approve the expropriation by a director or supervisor (for his or her own benefit or for the benefit of another person) of the individual rights of other shareholders, including, without limitation, rights to distributions and voting rights (but not according to a restructuring of our company which has been submitted for approval by the shareholders in a general meeting in accordance with our Articles of Association).

A controlling shareholder, however, will not be precluded by our Articles of Association or any laws and administrative regulations or the listing rules of the stock exchanges on which our shares are listed from voting on these matters.

A controlling shareholder is defined by our Articles of Association as any person who, acting alone or together with others:

• has the power to elect more than one-half of the Board of Directors;

• has the power to exercise, or to control the exercise of, 30% or more of our voting rights;

• holds 30% or more of our issued and outstanding shares; or

• has de facto control of us in any other way.

Minutes, Accounts and Annual Report

Our shareholders may inspect copies of the minutes of the shareholders’ general meetings during our business hours free of charge. Shareholders are also entitled to receive copies of these minutes within seven days of receipt of the reasonable charges we may require.

Our fiscal year is the calendar year ending December 31. Each fiscal year, we must mail our financial report to shareholders not less than 21 days before the date of the shareholders’ annual general meeting. These and any interim financial statements must be prepared in accordance with Chinese accounting standards and, for so long as H shares are listed on the HKSE, must also be prepared in accordance with or reconciled to either Hong Kong accounting standards or international accounting standards. The financial statements must be approved by an ordinary resolution of the shareholders at the annual general meeting.

Independent auditors are appointed each year by the shareholders at the annual meeting.

C. Material Contracts.

We have not entered into any material contracts in the last two years other than in the ordinary course of business and other than those described in Item 4. Information on the Company or elsewhere in this annual report on Form 20-F.

D. Exchange Controls.

Our Articles of Association require that cash dividends on our H Shares be declared in Renminbi and paid in HK dollars. The Articles of Association further stipulate that unless otherwise provided in law and administrative regulations, such dividends must be converted to HK dollars at a rate equal to the average of the closing exchange rates for HK dollars as announced by the Chinese Foreign Exchange Trading Center for the calendar week preceding the date on which the dividends are declared.

78

The Renminbi currently is not a freely convertible currency. The SAFE, under supervision of the People’s Bank of China (“PBOC”) controls the conversion of Renminbi into foreign currency. Chinese governmental policies were introduced in 1996 to reduce restrictions on the convertibility of Renminbi into foreign currency for current account items. In recent years, the Chinese government has gradually simplified and improved the foreign exchange administration policies in relation to capital items, such as the cancellation of foreign exchange registration and approval for domestic and overseas foreign direct investment. However, foreign exchange control over the capital items is not completely abolished. The limitations on foreign exchange could affect our ability to obtain foreign exchange through borrowings or equity financing, or to obtain foreign exchange for capital expenditures.

On July 21, 2005, the Chinese government changed its policy of pegging the Renminbi to the U.S. dollar. Under the new policy, the Renminbi is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. Since the adoption of this new policy, the value of the Renminbi has fluctuated daily within a narrow band, but overall has appreciated against the U.S. dollar. Nevertheless, the Chinese government continues to receive significant international pressure to further liberalize its currency policy which could result in a further and more significant appreciation in the value of the Renminbi against the U.S. dollar. The value of the Renminbi appreciated by 6.16% against the U.S. dollar in the year 2017.

While the impact of the foregoing developments is not entirely clear, it appears that the trend in the Chinese government’s foreign exchange policy is toward easier convertibility of the Renminbi.

The holders of the ADSs will receive the HK dollar dividend payments in U.S. Dollars at conversion rates related to market rates and subject to fees as set forth in our Deposit Agreement with The Bank of New York Mellon, as Depositary. The HK dollar is currently linked to and trades within a narrow band against the U.S. dollar at a rate that does not deviate significantly from HK$7.80 = U.S.$1.00. The Hong Kong government has stated its intention to maintain such link, although there can be no guarantee that such link will be maintained.

E. Taxation

PRC Taxation

The following is a summary of those taxes, including withholding provisions, to which United States security holders are subject under existing Chinese laws and regulations. The summary is subject to changes in Chinese law, including changes that could have retroactive effect. The summary does not take into account or discuss the tax laws of any country other than China, nor does it take into account the individual circumstances of a security holder. This summary does not purport to be a complete technical analysis or an examination of all potential tax effects under such laws and regulations.

Tax on Dividends

For an Individual Investor

According to the Individual Income Tax Law of the People’s Republic of China, as amended on June 30, 2011 (the “Individual Income Tax Law”) dividends paid by Chinese companies to individual investors are subject to Chinese withholding tax at a flat rate of 20%. As for a foreign individual investor that neither has a domicile nor resides in China, or that has no domicile and has resided in China for no more than one year, the dividends received by such an investor in China are generally subject to a withholding tax at a flat rate of 20% under the individual income tax law, subject to exemption or reduction by an applicable income tax treaty. According to the State Administration of Taxation’s tax treatments with regard to the dividends of H shares paid by onshore non-foreign invested enterprises listed on HKEx, we will withhold and pay the individual income tax at the tax rate of 10% for individual shareholders who are residents of Hong Kong, Macau, or countries which have entered into tax treaties with mainland China, which provide for a 10% dividends tax rate, and we will temporarily withhold and pay the individual income tax at the tax rate of 10% for individual shareholders who are residents of countries which have entered into tax treaties with mainland China, which provide for a less than 10% dividends tax rate. Shareholders of H Shares may directly or through our Company apply to the in-charge tax authority for the preferential treatments provided by the relevant tax treaties. Upon the approval by the in-charge tax authority, the excessive amount being paid will be refunded. For individual shareholders who are residents of countries which have entered into tax treaties with mainland China providing for a more than 10% but less than 20% dividends tax rate, we will withhold and pay the individual income tax at the specific tax rate required therein. We will withhold and pay the individual income tax at the dividends tax rate of 20% for individual shareholders who are residents of countries which have not entered into any forms of tax treaties with mainland China or in circumstances other than above described.

79

For a Corporation

According to the Enterprise Income Tax Law of the People’s Republic of China (“Enterprise Income Tax Law”) and its implementation rules, effective January 1, 2008, dividends by Chinese resident enterprises to non-resident enterprises are ordinarily subject to a Chinese withholding tax levied at a flat rate of 10%. For purposes of the Enterprise Income Tax Law, a “Chinese resident enterprise” is an enterprise which is either (i) set up in China in accordance with PRC laws or (ii) set up in accordance with the laws of a foreign country (region) but whose actual administrative headquarters is in China. For purposes of the Enterprise Income Tax Law, a “non-resident enterprise” is an enterprise which is set up in accordance with the laws of a foreign country (region) and whose actual administrative headquarters is located outside China but which has either (i) set up a legal presence in China or (ii) has income originating from China despite not having formally set up a legal presence in China. The State Administration of Taxation issued a Circular on Issues Relating to the Withholding of Enterprise Income Tax for Dividends Distributed by Resident Enterprises in China to Non-resident Enterprises Holding H-shares of the Enterprises (Guo Shui Han [2008] No. 897) on November 6, 2008, which further clarifies that Chinese resident enterprises should, in distributing dividends for 2008 or any year hereafter to non-resident enterprises holding H-shares of the Chinese resident enterprise, withhold enterprise income tax for such dividends at a tax rate of 10%. After receiving dividends, non-resident enterprises holding H-shares of any Chinese resident enterprise can, on their own or through an agent, file an application to the relevant taxation authorities for such dividends to be covered by any applicable tax treaty (or other arrangement). The relevant taxation authorities should, upon reviewing and verifying the application and supporting materials to be correct, refund the difference between the tax levied and the tax payable calculated at a tax rate specified by the applicable tax treaty (or other arrangement).

Capital Gains Tax

For an Individual Investor

So far as we are aware, in practice, capital gains derived by a foreign individual investor from the sale of overseas-listed shares are temporarily exempted from individual income tax.

For a Corporation

According to the Enterprise Income Tax Law and its implementation rules, a non-resident enterprise is subject to a 10% withholding tax for capital gains derived from the disposal of overseas-listed shares unless such payment is exempted or deducted pursuant to applicable double taxation treaties or otherwise. According to the Circular issued by the State Administration of Taxation on Issues regarding Income Tax Payable by Foreign Invested Enterprises, Foreign Enterprises and Individuals for Capital Gains Derived from the Disposal of Shares (Equity Interests) and Dividends (Guoshuifa [1993] No. 45), capital gains derived by a non-resident enterprise from the disposal of overseas-listed shares are temporarily exempted from withholding tax in China. However, this circular has been revoked in 2011. Therefore, technically, PRC withholding tax should be applied to non-resident enterprises on capital gains derived from the disposal of overseas-listed shares unless it is tax exempted under the applicable double tax treaty. So far as we are aware, practically, there is no consistent enforcement of the collection of such withholding tax in China at current stage. However, we are aware of cases where the PRC tax authorities try to levy PRC withholding tax when they became aware of the disposal of the overseas-listed shares that the profits from the disposal of shares are derived from China.

Tax Treaties

China has an income tax treaty with the United States that currently limits the rate of Chinese withholding tax to 10% for dividends paid to individuals and corporations that qualify for treaty benefits. However, this treaty does not offer reduced tax rates for capital gains.

However, if certain conditions under the double tax treaty are satisfied (e.g., the shareholding in H-shares is less than 25% and the H-share company is not ‘land rich’), the capital gains may be exempted from the 10% PRC withholding tax.

Stamp Tax

While no express exemption exists for the imposition of Chinese stamp tax on transfers of Overseas Shares pursuant to the Provisional Regulations of the People’s Republic of China Concerning Stamp Tax effective on July 1, 1989, we are not aware of any circumstance under which Chinese stamp tax has actually been imposed on the transfer of Overseas Shares.

Estate or Gift Tax

China does not currently impose any estate or gift tax.

U.S. Taxation

The following is a summary of the material U.S. federal income tax consequences of the ownership and disposition of H Shares or ADSs to U.S. Holders (as defined below). The following discussion is not exhaustive of all possible tax considerations. This summary is based upon the Internal Revenue Code of 1986, as amended (the “Code”), regulations promulgated under the Code by the U.S. Treasury Department (including proposed and temporary regulations), rulings, current administrative interpretations and official pronouncements of the Internal Revenue Service (“IRS”), and judicial decisions, all as currently available and all of which are subject to differing interpretations or to change, possibly with retroactive effect. Such change could materially and adversely affect the tax consequences described below. No assurance can be given that the IRS will not assert, or that a court will not sustain, a position contrary to any of the tax consequences described below.

80

This discussion does not address state, local, or foreign tax consequences, or the net investment income tax consequences, of the ownership and disposition of H Shares or ADSs. (See “PRC Taxation” above).

This summary is for general information only and does not address all aspects of U.S. federal income taxation that may be important to a particular holder in light of its investment or tax circumstances or to holders subject to special tax rules, such as: banks; financial institutions; insurance companies; dealers in stocks, securities, or currencies; entities treated as partnerships for U.S. federal income taxes or partners therein; traders in securities that elect to use a mark-to-market method of accounting for their securities holdings; tax-exempt organizations; real estate investment trusts; regulated investment companies; qualified retirement plans, individual retirement accounts, and other tax-deferred accounts; expatriates of the United States; individuals subject to the alternative minimum tax; persons holding H Shares or ADSs as part of a straddle, hedge, conversion transaction, or other integrated transaction; persons who acquired H Shares or ADSs pursuant to the exercise of any employee stock option or otherwise as compensation for services; persons actually or constructively holding 10% or more of the voting power or value of our stock; U.S. Holders (as defined below) whose functional currency is other than the U.S. dollar; and persons holding our H Shares or ADSs in connection with a trade or business conducted outside the United States.

This discussion is not a comprehensive description of all of the U.S. federal tax consequences that may be relevant with respect to the ownership and disposition of H Shares or ADSs. We urge you to consult your own tax advisor regarding your particular circumstances and the U.S. federal income and estate tax consequences to you of owning and disposing of H Shares or ADSs, as well as any tax consequences arising under the laws of any state, local, or foreign or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws.

This summary is directed solely to U.S. Holders (defined below) who hold their H Shares or ADSs as capital assets within the meaning of Section 1221 of the Code, which generally means as property held for investment. For purposes of this discussion, the term “U.S. Holder” means a beneficial owner of H Shares or ADSs that is any of the following:

• a citizen or resident of the United States or someone treated as a U.S. citizen or resident for U.S. federal income tax purposes;

• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia; or

• a trust or estate, the income of which is subject to U.S. federal income taxation regardless of its source.

ADSs

As it relates to the ADSs, this discussion is based in part upon the representations of the depositary and the assumption that each obligation in the Deposit Agreement and any related agreement will be performed in accordance with its terms.

Generally, a holder of ADSs will be treated as the owner of the underlying H Shares represented by those ADSs for U.S. federal income tax purposes. Accordingly, no gain or loss will be recognized if the holder exchanges ADSs for the underlying H Shares represented by those ADSs. The holder’s adjusted tax basis in the H Shares will be the same as the adjusted tax basis of the ADSs surrendered in exchange therefor, and the holding period for the H Shares will include the holding period for the surrendered ADSs.

TAXATION OF U.S. HOLDERS

The discussion in “Distributions on H Shares or ADSs” and “Dispositions of H Shares or ADSs” below assumes that we will not be treated as a PFIC for U.S. federal income tax purposes. For a discussion of the rules that apply if we are treated as a PFIC, see the discussion in “Passive Foreign Investment Company” below.

Distributions on H Shares or ADSs

General. Subject to the discussion in “Passive Foreign Investment Company” below, if you actually or constructively receive a distribution on H Shares or ADSs, you must include the distribution in gross income as a taxable dividend on the date of your (or in the case of ADSs, the depositary’s) receipt of the distribution, but only to the extent of our current or accumulated earnings and profits, as calculated under U.S. federal income tax principles. Such amount must be included without reduction for any foreign taxes withheld. Dividends paid by us will not be eligible for the dividends received deduction allowed to corporations with respect to dividends received from certain domestic corporations. Dividends paid by us may or may not be eligible for preferential rates applicable to qualified dividend income, as described below.

To the extent a distribution exceeds our current and accumulated earnings and profits, it will be treated first as a non-taxable return of capital to the extent of your adjusted tax basis in the H Shares or ADSs, and thereafter as capital gain. Preferential tax rates for long term capital gain may be applicable to non-corporate U.S. Holders.

We do not intend to calculate our earnings and profits under U.S. federal income tax principles. Therefore, you should expect that a distribution generally will be reported as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above.

81

Qualified Dividend Income. With respect to non-corporate U.S. Holders (i.e., individuals, trusts, and estates), dividends that are treated as qualified dividend income (“QDI”) are taxable at a maximum tax rate of 20%. Among other requirements, dividends generally will be treated as QDI if either (i) our H Shares or ADSs are readily tradable on an established securities market in the United States, or (ii) we are eligible for the benefits of a comprehensive income tax treaty with the United States which includes an information exchange program and which is determined to be satisfactory by the U.S. Treasury. It is expected that our ADSs will be “readily tradable” as a result of being listed on the NYSE.

In addition, for dividends to be treated as QDI, we must not be a PFIC (as discussed below) for either the taxable year in which the dividend was paid or the preceding taxable year. We do not believe that we were a PFIC for the preceding taxable year or will be a PFIC for the current taxable year. However, please see the discussion under “Passive Foreign Investment Company” below. Additionally, in order to qualify for QDI treatment, you generally must have held the H Shares or ADSs for more than 60 days during the 121-day period beginning 60 days prior to the ex-dividend date. However, your holding period will be reduced for any period during which the risk of loss is diminished.

Moreover, a dividend will not be treated as QDI to the extent you are under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property. Since the QDI rules are complex, you should consult your own tax advisor regarding the availability of the preferential tax rates for dividends paid on H Shares or ADSs.

Foreign Currency Distributions. A dividend paid in foreign currency (e.g., Hong Kong dollars or Chinese Renminbi) must be included in your income as a U.S. dollar amount based on the exchange rate in effect on the date such dividend is received, regardless of whether the payment is in fact converted to U.S. Dollars. If the dividend is converted to U.S. Dollars on the date of receipt, you generally will not recognize a foreign currency gain or loss. However, if you convert the foreign currency to U.S. Dollars on a later date, you must include in income any gain or loss resulting from any exchange rate fluctuations. The gain or loss will be equal to the difference between (i) the U.S. dollar value of the amount you included in income when the dividend was received and (ii) the amount that you receive on the conversion of the foreign currency to U.S. Dollars. Such gain or loss generally will be ordinary income or loss and U.S. source for U.S. foreign tax credit purposes.

Foreign Tax Credits. Subject to certain conditions and limitations, any foreign taxes paid on or withheld from distributions from us and not refundable to you may be credited against your U.S. federal income tax liability or, alternatively, may be deducted from your taxable income. This election is made on a year-by-year basis and applies to all foreign taxes paid by you or withheld from you that year.

Distributions will constitute foreign source income for foreign tax credit limitation purposes. The foreign tax credit limitation is calculated separately with respect to specific classes of income. For this purpose, distributions characterized as dividends distributed by us generally will constitute “passive category income” or, in the case of certain U.S. Holders, “general category income.” Special limitations may apply if a dividend is treated as QDI (as defined above).

Since the rules governing foreign tax credits are complex, you should consult your own tax advisor regarding the availability of foreign tax credits in your particular circumstances.

Dispositions of H Shares or ADSs

Subject to the discussion in “Passive Foreign Investment Company” below, you generally will recognize taxable gain or loss realized on the sale or other taxable disposition of H Shares or ADSs equal to the difference between the U.S. dollar value of (i) the amount realized on the disposition (i.e., the amount of cash plus the fair market value of any property received), and (ii) your adjusted tax basis in the H Shares or ADSs. Such gain or loss will be a capital gain or loss. Capital gain from the sale or other taxable disposition of H Shares or ADSs held by certain non-corporate U.S. Holders will be taxed at preferential rates if such H Shares or ADSs have been held for more than one year and certain other requirements are met. The deductibility of capital losses is subject to limitations. Any gain or loss recognized generally will be treated as gain or loss from sources within the United States for U.S. foreign tax credit limitation purposes.

You should consult your own tax advisor regarding the U.S. federal income tax consequences if you receive currency other than U.S. Dollars upon the disposition of H Shares or ADSs.

Passive Foreign Investment Company

We generally will be a PFIC under Section 1297 of the Code if, for a taxable year, either (a) 75% or more of our gross income for such taxable year is passive income (the “income test”) or (b) 50% or more of the average percentage, generally determined by fair market value, of our assets during such taxable year either produce passive income or are held for the production of passive income (the “asset test”). “Passive income” includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.

82

Certain “look through” rules apply for purposes of the income and asset tests described above. If we own, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, we generally will be treated as if we (a) held directly a proportionate share of the other corporation’s assets, and (b) received directly a proportionate share of the other corporation’s income. In addition, passive income does not include any interest, dividends, rents, or royalties that are received or accrued by us from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to income of such related person that is not passive income.

Under the income and asset tests, whether or not we are a PFIC will be determined annually based upon the composition of our income and the composition and valuation of our assets, all of which are subject to change. In determining that we are not a PFIC, we are relying on a current valuation of our assets including goodwill, not reflected in our financial statements, and our projection of our income for the current year. We determine the value of our assets in large part by reference to the market value of our ordinary shares at the end of each quarter. We believe this valuation approach is reasonable. However, if the IRS successfully challenged our valuation of our assets, or if the market price of our ordinary shares were to fluctuate, it could result in our classification as a PFIC.

We do not believe that we are currently a PFIC. However, because the PFIC determination is highly fact intensive and made at the end of each taxable year, there can be no assurance that we will not be a PFIC for the current or any future taxable year or that the IRS will not challenge our determination concerning our PFIC status.

If we are a PFIC for any taxable year during which a U.S. Holder holds H Shares or ADSs, we generally will continue to be treated as a PFIC with respect to such holder for all succeeding years during which such holder holds H Shares or ADSs, regardless of whether we continue to meet the income or asset test. If we are classified as a PFIC, U.S. Holders could be subject to additional taxes and a special interest charge in respect of gain recognized on the sale or other disposition of such holder’s H Shares or ADSs and upon the receipt of “excess distributions” (as defined in the Code). In addition, no distribution that U.S. Holders receive from us would qualify for taxation at the preferential rate discussed in “—Distributions on H Shares or ADSs” above, if we were a PFIC for the taxable year of such distribution or for the preceding taxable year. Moreover, U.S. Holders may be required to file annual tax returns (including on Form 8621) containing such information as the U.S. Treasury requires.

Information reporting regarding specified foreign financial assets

Certain U.S. Holders who are individuals (and under proposed regulations, certain entities) may be required to report information relating to an interest in our H Shares or ADSs, subject to certain exceptions (including an exception for shares held in accounts maintained by U.S. financial institutions). U.S. Holders are urged to consult their tax advisors regarding their information reporting obligations, if any, with respect to their ownership and disposition of our H Shares or ADSs. In the event a U.S. Holder does not file such required reports, the statute of limitations on the assessment and collection of U.S. federal income taxes of such U.S. holder for the related tax year will not close before such report is filed.

If you are a U.S. Holder, you are urged to consult with your own tax advisor regarding the application of the specified foreign financial assets information reporting requirements and related statute of limitations tolling provisions with respect to our H Shares and ADSs.

Information Reporting and Backup Withholding

Generally, information reporting requirements will apply to distributions on H Shares or ADSs or proceeds from the disposition of H Shares or ADSs paid within the United States (and, in certain cases, outside the United States) to a U.S. Holder unless such U.S. Holder is an exempt recipient, such as a corporation. Furthermore, backup withholding (currently at 24%) may apply to such amounts unless such U.S. Holder (i) is an exempt recipient that, if required, establishes its right to an exemption, or (ii) provides its taxpayer identification number, certifies that it is not currently subject to backup withholding, and complies with other applicable requirements.

A U.S. Holder may generally avoid backup withholding by furnishing a properly completed IRS Form W-9.

Backup withholding is not an additional tax. Rather, amounts withheld under the backup withholding rules may be credited against your U.S. federal income tax liability. Furthermore, you may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS and furnishing any required information in a timely manner.

H. Documents on Display.

We are subject to the periodic reporting and other informational requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Under the Exchange Act, we are required to file reports and other information with the Securities and Exchange Commission. Specifically, we are required to file annually a Form 20-F no later than four months after the close of each fiscal year, which is December 31 of each year. Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the public reference facilities maintained by the Securities and Exchange Commission at 100 F Street, N.E., Washington, D.C. 20549.

The SEC also maintains a Web site at www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGAR system. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and officers, directors and principal shareholders are exempt from the reporting and short- swing profit recovery provisions contained in Section 16 of the Exchange Act.

I. Subsidiary Information.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our market risk exposures primarily consist of fluctuations in oil and gas prices, exchange rates and interest rates.

Commodity Price Risk

We are exposed to commodity price risk related to price volatility of crude oil and refined oil products. We had no program of commodity price hedging activities and did not engage in any such activities in 2016 or 2017. See Item 3. Key Information – D. Risk Factors – Our operations may be adversely affected by the cyclical nature of the petroleum and petrochemical market and by the volatility of prices of crude oil and petrochemical products.

Interest Rate Risk

We are subject to risk resulting from fluctuations in interest rates. Our borrowings are fixed and variable rate bank and other borrowings, with original maturities ranging from 1 to 5 years. Accordingly, fluctuations in interest rates can lead to significant fluctuations in the fair value of such debt instruments. We had no program of interest rate hedging activities and did not engage in any such activities in 2016 or 2017.

The following table provides information, by maturity date, regarding our interest rate sensitive financial instruments, which consist of fixed and variable rate short term and long term debt obligations, as of December 31, 2017 and 2016.

D. American Depositary Shares.

In connection with our ADR program, a holder of our ADSs may have to pay, either directly or indirectly, certain fees and charges, as described in Item 12.D.3. In addition, we receive fees and other direct and indirect payments from The Bank of New York Mellon that are related to our ADS as described in Item 12.D.4.

86

12.D.3 Fees and Charges that a holder of our ADSs May Have to Pay

The Bank of New York Mellon collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Bank of New York Mellon also collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Bank of New York Mellon may collect its annual fee for depositary services by deductions from cash distributions.

Persons depositing or withdrawing shares must pay:	For:
$5.00 (or less) per 100 ADSs (or portion of 100 ADSs)	Issuance and withdrawal of ADSs, including issuances resulting from a distribution of shares or rights or other property
A fee equivalent to the fee that would be payable if securities distributed to you had been shares and the shares had been deposited for issuance of ADSs	Distribution of securities distributed to holders of deposited securities which are distributed by The Bank of New York Mellon to ADS registered holders
A fee of $.05 (or less) per ADS (or portion thereof)	Any cash distribution made pursuant to the Deposit Agreement
Registration or transfer fees	Transfer and registration of shares on our share register to or from the name of the depositary or its agent when you deposit or withdraw shares
Expenses of The Bank of New York Mellon	Cable, telex and facsimile transmissions (when expressly provided in the Deposit Agreement); Converting foreign currency to U.S. Dollars

PART II

ITEM 13. DEFAULTS, DIVIDEND ARREARAGES AND DELINQUENCIES.

None.

ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS.

On May 11, 2011, we entered into an Amended and Restated Deposit Agreement with The Bank of New York Mellon, as Depositary (the “ Restated Deposit Agreement”), and updated the form of American Depositary Receipt (the “ADR”) evidencing the ADSs issued under the terms of the Restated Deposit Agreement. The Restated Deposit Agreement restates our original Deposit Agreement with The Bank of New York (the predecessor of The Bank of New York Mellon), dated as of July 23, 1993 (as amended, the “1993 Deposit Agreement”), in its entirety.

We and The Bank of New York Mellon entered into the Restated Deposit Agreement to modify the ADSs voting process and to bring our arrangements with The Bank of New York Mellon in line with the current customary market practice regarding depositary arrangements.

By the Restated Deposit Agreement, subject to the Depositary’s obligation to notify the owner of ADSs of any meeting of holders of our shares or other deposited securities, and subject further to certain exceptions as provided therein, to the extent that no instructions are received by the Depositary from an owner of ADSs on or before the date established by the Depositary, the Depositary may deem instructions by the owner of the ADS have been given to give a discretionary proxy to a person designated by us to exercise voting rights in the meeting of holders of our shares or other deposited securities.

In addition, the Restated Deposit Agreement amends the 1993 Deposit Agreement, among other things, to (i) provide the American Depositary Shares may be uncertificated securities or certificated securities evidenced by ADRs, and (ii) change the fees and charges of the Depositary, see Item 12D.3 Fees and Charges that a holder of our ADSs May Have to Pay.

The foregoing descriptions of the Restated Deposit Agreement and the ADR do not purport to be complete and are qualified in their entirety by reference to the complete Restated Deposit Agreement and ADR which are incorporated herein by reference to Exhibit 2 and the forms filed on Form F-6 (File number 033-65616) on May 4, 2011.

ITEM 15. CONTROLS AND PROCEDURES.

(a). Disclosure Controls And Procedures.

The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. These rules refer to the controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files under the Exchange Act is recorded, processed, summarized and reported within required time periods. This includes controls and procedures designed to ensure that information required to be disclosed is accumulated and communicated to our management, including our principal executive officer or officers and principal financial officer or officers, to allow timely decisions regarding required disclosure.

We maintain a written policy adopted by our Board of Directors that governs the collection, coordination and disclosure of information to our shareholders, the public and to governmental and other regulatory bodies. All such disclosures are coordinated by the Secretary to our Board of Directors and subject to execution by either the Chairman of our Board of Directors or, for disclosures by our Supervisory Committee, the Chairman of the Supervisory Committee. Under the policy, all material issues must be disclosed and our disclosures must be true, accurate, complete and timely without any false or misleading statements. Each of our departments and subsidiaries has their own supplemental policies which may be both written and unwritten.

88

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) as of the end of the fiscal year covered by this annual report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the fiscal year covered by this annual report, our disclosure controls and procedures were effective to ensure that information required to be disclosed in the reports we file under the Exchange Act is accumulated and communicated to the management to allow timely decisions to be made regarding required disclosures, and is recorded, processed, summarized and reported as and when required.

(b). Management’s Report on Internal Control over Financial Reporting.

Our management is accountable for establishing and maintaining effective internal control over financial reporting (as defined in Rules 13a-15(f) of the Securities Exchange Act of 1934). The 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.

Because of its inherent limitations, internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives and 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 ineffective because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting based upon the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) as of December 31, 2017. Based on that evaluation, our management has concluded that our internal control over financial reporting was effective as of December 31, 2017 based on these criteria.

PricewaterhouseCoopers Zhong Tian LLP (“PwC”), an independent registered public accounting firm, has audited the consolidated financial statements included in this annual report on Form 20-F and, as part of the audit, has issued a report, included herein, on the effectiveness of our internal control over financial reporting.

(c). Report of Independent Registered Public Accounting Firm.

Our independent auditors have issued an audit report on the effectiveness of our internal control over financial reporting. This report appears on page F-2.

(d). Changes in Internal Control over Financial Reporting.

For the year ended December 31, 2017, there have been no changes to our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.

ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT.

Our Board of Directors has determined that Ms. Li Yuanqin who is currently serving on our audit committee, is an audit committee financial expert and is an Independent Director (under the standards set forth in the NYSE rules and Rule 10A-3 of the Exchange Act).

ITEM 16B. CODE OF ETHICS.

Sinopec Group Company, the controlling shareholder of Sinopec Corp., adopted a Staff Code in 2014 to provide disciplines and requirements for its staff’s conducts, including legal and ethical matters as well as the sensitivities involved in reporting illegal and unethical matters. The Staff Code covers such areas as health, safety and environment, conflict of interests, anti-corruption, protection and proper use of our assets and properties, as well as reporting requirements. The Staff Code also applies to all directors, officers and employees of each subsidiary of Sinopec Group Company, including us. We have provided all our directors and senior officers with a copy of the Staff Code and required them to comply with in it order to ensure our operations are proper and lawful. We have posted the Staff Code on the following website: http://www.sinopec.com/listco/en/Resource/Pdf/ygsz2014b.pdf.

ITEM 16G. CORPORATE GOVERNANCE.

Set forth below is a summary of the significant differences between the corporate governance rules of the NYSE and those of the People’s Republic of China for listed companies:

	NYSE Corporate Governance Rules	The Company’s Corporate Governance Practices (which conform with the corporate governance rules for companies organized and listed in the People’s Republic of China)
Director Independence	A listed company must have a majority of independent directors on its board of directors. The board of directors needs to affirmatively determine that the director has no material relationship with the listed company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company). In addition, a director must meet certain standards to be deemed independent.	It is required in China that no less than 1/3rd of the board members of any listed company must be independent directors, and the listed company must set forth specific requirements for the qualification and election of independent directors in compliance with PRC laws. For example, an independent director shall not hold any other position in the listed company other than being a director and shall not be influenced by the main shareholders or the controlling persons of the listed company, or by any other entities or persons with whom the listed company has a significant relationship. The Company has complied with the relevant Chinese corporate governance rules and has implemented internal rules governing the independence and responsibilities of independent directors. The Company determines the independence of independent directors every year.
	The non-management directors of each listed company must meet at regularly scheduled executive sessions without management.	No similar requirements.
Nominating/Corporate Governance Committee	Listed companies must have a nominating/corporate governance committee composed entirely of independent directors.	The board of directors can establish a nominating committee if the shareholders pass resolutions to establish such a committee. A majority of the directors on the committee shall be independent directors, who shall act as the convener. The board of directors, which formulates relevant written guidelines with respect to the nomination of directors, has established a nominating committee with a majority of the members being independent directors.

91

	The nominating/corporate governance committee must have a written charter that addresses: (i) the committee’s purpose and responsibilities - which, at minimum, must be to: identify individuals qualified to become board members, consistent with criteria approved by the board, and to select, or to recommend that the board select, the director nominees for the next annual meeting of shareholders; develop and recommend to the board a set of corporate governance guidelines applicable to the corporation; and oversee the evaluation of the board and management; and (ii) an annual performance evaluation of the committee.	Relevant responsibilities of the nominating committee are similar to those stipulated by the NYSE rules, but the main responsibilities do not include the research and recommendation of corporate governance guidelines, the supervision of the evaluation of the board of directors and management, or the annual evaluation of the committee.
Compensation Committee	Listed companies must have a compensation committee composed entirely of independent directors.	The board of directors can establish a compensation and assessment committee if the shareholders pass resolutions to establish such a committee. A majority of the directors on the committee shall be independent directors, who shall act as the convener.
	The purposes and responsibilities of the compensation committee stated in its charter must include: (1) reviewing and approving the corporate goals and objectives associated the with the CEO’s compensation, evaluate the performance of the CEO in fulfilling these goals and objectives, and, either as a committee or together with the other independent directors (as directed by the board), determine and approve the CEO’s compensation level based on such evaluation; (2) making recommendations to the board with respect to non-CEO executive officer compensation, and incentive-compensation and equity-based plans that are subject to board approval; and (3) producing a committee report on executive compensation as required by the SEC to be included in the annual proxy statement or annual report filed with the SEC. The charter must also include the requirement for an annual performance evaluation of the compensation committee.	The responsibilities of the compensation and assessment committee include: (1) reviewing the standards for the evaluation of directors and management, evaluate directors and management and report the results of such evaluation to the board of directors; and (2) reviewing compensation policies and benefit plans for directors and executive officers. Unlike the NYSE rules, the PRC rules do not require the committee to produce a report on the executive compensation or make an annual performance evaluation of the committee. In addition, the compensation committee evaluates and reviews the compensation of directors as well as executive officers. The board of directors of the Company has established a compensation evaluation committee with a majority of the members being independent directors who act as the convener, and the committee has established a written charter complying with the domestic corporate governance rules.

92

Audit Committee	Listed companies must have an audit committee that satisfies the requirements of Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). It must have a minimum of three members, and all audit committee members must satisfy the requirements for independence set forth in Section 303A.02 of the NYSE Corporate Governance Rules and , in the absence of an applicable exemption, Rule 10A-3b(1) of the Exchange Act. The written charter of the audit committee must specify that the purpose of the audit committee is to assist the board oversight of the integrity of financial statements, the company’s compliance with legal and regulatory requirements, the qualifications and independence of the independent auditors, the performance of the listed company’s internal audit function and independent auditors. The written charter must also require the audit committee to prepare an audit committee report as required by the SEC to be included in the listed company’s annual proxy statement as well as an annual performance evaluation of the audit committee. The written charter must also address the duties and responsibilities of the audit committee as required under Section 303A.07 of the NYSE Corporate Governance Rules.	The board of directors of a listed company can, through the resolution of the shareholders’ meeting, establish an audit committee composed entirely of directors, of which the independent directors are the majority and act as the convener, and, at minimum, one independent director is an accounting professional. The purpose, authority and responsibilities of the audit committee are similar to those stipulated by the NYSE rules, but according to customary practices in China, the Company is not required to make an annual performance evaluation of the audit committee, and the audit committee is not required to prepare an audit report to be included in the Company’s annual proxy statement. The board of directors of the Company has established an audit committee that satisfies Rule 10A-3 under the Securities Exchange Act of 1934, as amended and relevant domestic requirements. The audit committee has a written charter.
Strategy Committee	N/A	The board of directors of a listed company can, through the resolution of the shareholders’ meeting, establish a strategy committee composed entirely of directors. We formed a strategy committee on June 15, 2017. The key responsibility of the Strategy Committee is to conduct researches and give recommendations to the Board on major investment decisions, projects and major issues that affect our development, and monitor our long-term development strategic plan.
	Each listed company must maintain an internal audit function to provide management and the audit committee with ongoing assessments of the listed company’s risk management processes and system of internal controls.	China has a similar regulatory provision, and the Company has an internal audit department.

Equity Compensation	Shareholders must be given the opportunity to vote on all equity compensation plans and material revisions thereto, except for employment inducement awards, certain grants, plans and amendments in the context of mergers and acquisitions, and certain specific types of plans as described under Section 303A.08 of the NYSE Corporate Governance Rules.	The relevant regulations of China require the board of directors propose plans on the amount and types of director compensation for the shareholders’ meeting to approve. The compensation plan of executive officers shall be approved by the board and announced at the shareholders’ meeting and disclosed to the public upon the approval of the board of directors.
Corporate Governance Guidelines	Listed companies must adopt and disclose corporate governance guidelines involving director qualification standards, director responsibilities, director compensation, director access to management and, as necessary and appropriate, independent advisors, director orientation and continuing education and management succession. The board should conduct a self-evaluation at least annually to determine whether it and its committees are functioning effectively. A listed company must make its corporate governance guidelines available on or through its website.	The CSRC has issued the Corporate Governance Rules, prescribing detailed guidelines on directors of the listed companies, including director selection, the structure of the board of directors and director performance evaluation. The Company has complied with the above mentioned rules.
Code of Ethics for Directors, Officers and Employees	Listed companies must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers. Each listed company may determine its own policies, but all listed companies should address the most important topics, including, among others, conflicts of interest, corporate opportunities, confidentiality, fair dealing, protection and proper use of listed company assets, compliance with laws, rules and regulations (including insider trading laws), and encouraging the reporting of any illegal or unethical behavior.	There is no such requirement for a code for ethics in China. As the directors and officers of the Company have all signed a Director Service Agreement, however, they are bound by their fiduciary duties to the Company. In addition, the directors and officers must perform their legal duties in accordance with the PRC Company Law, relevant requirements of CSRC and Mandatory Provisions to the Charter of Companies Listed Overseas.
	Each listed company CEO must certify to the NYSE each year that he or she is not aware of any violation by the company of NYSE corporate governance listing standards and he or she must promptly notify the NYSE in writing of any non-compliance with any applicable provisions of Section 303A.	No similar requirements.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Sinopec Shanghai Petrochemical Company Limited

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Sinopec Shanghai Petrochemical Company Limited and its subsidiaries (the “Company”) as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2017, 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, 2017, 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, 2017 and 2016, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2017 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, 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 Report on Internal Control over Financial Reporting appearing under Item 15. Our responsibility is to express opinions on the 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.

F - 2

Basis for Opinions (continued)

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.

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.

Sinopec Shanghai Petrochemical Company Limited

Notes to the Consolidated Financial Statements

For the year ended 31 December 2017

1 General information

Sinopec Shanghai Petrochemical Company Limited (“the Company”), formerly Shanghai Petrochemical Company Limited, was established in the People’s Republic of China (“the PRC”) on 29 June 1993 as a joint stock limited company to hold the assets and liabilities of the production divisions and certain other units of Shanghai Petrochemical Complex (“SPC”), a state-owned enterprise. The Company was under the direct supervision of China Petrochemical Corporation (“Sinopec Group”) at that time.

The Company completed its initial public offerings in 1993. Its shares were listed on the Stock Exchange of Hong Kong Limited (“H shares”) and the New York Stock Exchange in the form of American Depositary Shares (“ADS”) on 26 July 1993, and were also listed on the Shanghai Stock Exchange (“ordinary A shares”) on 8 November 1993.

Sinopec Group completed its reorganisation on 25 February 2000. After the reorganisation, China Petroleum & Chemical Corporation (“Sinopec Corp.”) was established. As part of the reorganisation, Sinopec Group transferred its 4,000,000,000 of the Company’s state-owned legal shares, which represented 55.56 percent of the issued share capital of the Company, to Sinopec Corp.

The Company changed its name to Sinopec Shanghai Petrochemical Company Limited on 12 October 2000, and Sinopec Corp. was the largest shareholder of the Company.

Pursuant to the “Approval on matters relating to the Share Segregation Reform of Sinopec Shanghai Petrochemical Company Limited” issued by the State-owned Assets Supervision and Administration Commission of the State Council (State Owned Property [2013] No.443), a General Meeting of A share shareholders was held on 8 July 2013 and passed the resolution of “Share Segregation Reform of Sinopec Shanghai Petrochemical Company Limited (Amendment)” (“the Share Segregation Reform Resolution”) which was published by the Company on Shanghai Stock Exchange (“SSE”) website on 20 June 2013.

According to the Share Segregation Reform Resolution, the controlling shareholder of the Company, Sinopec Corp., offered shareholders of circulating A shares 5 shares for every 10 circulating A shares they held on 16 August 2013, aggregating 360,000,000 A shares, for the purpose of obtaining the listing rights of its non-circulating shares in the A Shares market. From 20 August 2013 (“the circulation date”), all the Company’s non-circulating A shares have been granted circulating rights on Shanghai Stock Exchange (“SSE”). As part of the restricted conditions, Sinopec Corp. committed that all the 3,640,000,000 A shares held were not allowed to be traded on SSE or transferred within 12 months from the circulation date (“the restriction period”). After the restriction period, Sinopec Corp. can only sell no more than 5 and 10 percent of its total shares within 12 and 24 months, respectively. The former 150,000,000 non-circulating A shares held by social legal persons were also prohibited to be traded on SSE or transferred within 12 months from the circulation date. Meanwhile, Sinopec Corp. also committed in the Share Segregation Reform Resolution that a scheme of converting surplus to share capital (no less than 4 shares for every 10 shares) will be proposed on the board of directors and shareholders meetings within 6 months after the circulation date.

The 15th meeting of the 7th term of Board of Directors was held on 28 August 2013 and the Company proposed and passed a resolution regarding interim cash dividend for the first half of 2013 and the conversion of share premium and surplus reserve to share capital. The resolution included a distribution of 5 shares and a cash dividend distribution of RMB 0.5 (tax included) for every 10 shares based on the 7,200,000 thousands ordinary shares as at 30 June 2013. Among the 5 shares distributed, 3.36 shares were converted from share premium of RMB 2,420,841 thousands and 1.64 shares were converted from surplus reserves of RMB 1,179,159 thousands. The resolution were approved by the extraordinary general meeting of shareholders, A share class shareholders meeting and H share class shareholders meeting on 22 October 2013, respectively.

The first tranche of the Share Option Incentive Scheme was exercised on 29 August 2017, and the Company received cash payment of RMB 54,580 thousands from 199 grantees. As a result, ordinary A shares of 14,177 thousands were registered on 27 September 2017.

As at 31 December 2017, total shares of the Company were 10,814,177 thousands (31 December 2016: 10,800,000 thousands).

Notes to the Consolidated Financial Statements

For the year ended 31 December 2017

1 General information (continued)

The Company and its subsidiaries (“the Group”) are principally engaged in processing crude oil into synthetic fibres, resins and plastics, intermediate petrochemicals and petroleum products.

These consolidated financial statements are presented in thousands of Renminbi Yuan (RMB), unless otherwise stated. These financial statements have been approved for issue by the Board of Directors on 27 April 2018.

2 Summary of significant accounting policies

The principal accounting policies applied in the preparation of these consolidated financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

2.1 Basis of preparation

The consolidated financial statements of the Group have been prepared in accordance with all applicable International Financial Reporting Standards (“IFRS”) as issued by International Accounting Standards Board (“IASB”). The consolidated financial statements have been prepared under the historical cost convention, as modified by the revaluation of financial assets and financial liabilities at fair value through profit or loss, which are carried at fair value.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 4.

2.1.1 Changes in accounting policy and disclosures

(a) New and amended standards adopted by the Group

The following new and amended standards and interpretations are effective for the financial year beginning on 1 January 2017. None of them has a material impact on the Group.

Amendments to IAS 7, ‘Statement of cash flows’

Amendments to IAS 12, ‘Income taxes’

Amendment to IFRS 12, ‘Disclosure of interest in other entities’

There are no other amended standards or interpretations that are effective for the first time for this annual period that could be expected to have a material impact on the Group.

(b) New standards and interpretations not yet adopted

Certain new accounting standards and interpretations have been published that are not mandatory for 31 December 2017 reporting periods and have not been early adopted by the Group. The Group’s assessment of the impact of these new standards and interpretations is set out below.

IFRS 9, ‘Financial instruments’, addresses the classification, measurement and derecognition of financial assets and financial liabilities. The complete version of IFRS 9 was issued in July 2014. It replaces the whole of IAS 39. IFRS 9 introduces a new model for the recognition of impairment losses – the expected credit losses (ECL) model, which constitutes a change from the incurred losses model in IAS 39. IFRS 9 applies to all hedging relationships, with the exception of portfolio fair value hedges of interest rate risk. The new guidance better aligns hedge accounting with the risk management activities of an entity and provides relief from the more “rule-based” approach of IAS 39. IFRS 9 is effective for annual periods beginning on or after 1 January 2018 and the Group will apply the new rules retrospectively from 1 January 2018, with the practical expedients permitted under the standard. It is not expected to have any significant impact on the consolidated financial statement of the Group.

2 Summary of significant accounting policies (continued)

2.1 Basis of preparation (continued)

2.1.1 Changes in accounting policy and disclosures (continued)

(b) New standards and interpretations not yet adopted (continued)

IFRS 15, ‘Revenue from contracts with customers’, establishes a comprehensive framework for determining when to recognize revenue and how much revenue to recognise through a 5-step approach. IFRS 15 provides specific guidance on capitalisation of contract cost and licence arrangements. It also includes a cohesive set of disclosure requirements about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. The core principle is that a company should recognise revenue to depict the transfer of promised goods or services to the customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. IFRS 15 replaces the previous revenue standards: IAS 18 ‘Revenue’ and IAS 11 ‘Construction Contracts’ and the related Interpretations on revenue recognition: IFRIC 13 ‘Customer Loyalty Programmes’, IFRIC 15 ‘Agreements for the Construction of Real Estate’, IFRIC 18 ‘Transfers of Assets from Customers’ and SIC-31 ‘Revenue—Barter Transactions Involving Advertising Services’. IFRS 15 is effective for annual reporting periods beginning on or after 1 January 2018.

The application of HKFRS 15 may further result in the identification of separate performance obligations in relation to shipping service derived from oversea trading sales of the Group which could affect the timing of the recognition of revenue, from point in time to overtime going forward. The standard permits either a full retrospective or a modified retrospective approach for the adoption. Mandatory for financial years commencing on or after 1 January 2018. The Group intends to adopt the standard using the modified retrospective approach which means that the cumulative impact of the adoption will be recognised in retained earnings as of 1 January 2018 and that comparatives will not be restated.

IFRS 16, ‘Leases’, provides updated guidance on the definition of leases, and the guidance on the combination and separation of contracts. Under IFRS 16, a contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. IFRS 16 requires lessees to recognise lease liability reflecting future lease payments and a ‘right-of-use-asset’ for almost all lease contracts, with an exemption for certain short-term leases and leases of low value assets. The lessors accounting stays almost the same as under IAS 17 ‘Leases’. IFRS 16 is effective for annual reporting periods beginning on or after 1 January 2019.

The standard will affect primarily the accounting for the Group’s operating leases when the Group is as the leasee in those leases. As at the reporting date, the Group has non-cancellable operating lease commitments, as disclosed in Note 33(b). The Group is still evaluating the effects of the new standard on the other lease commitments with the lease term greater than one year and intends to apply the simplified transition approach and will not restate comparative amounts for the year prior to first adoption. At this stage, the Group does not intend to adopt the standard before its effective date.

There are no other standards that are not yet effective and that would be expected to have a material impact on the Group in the current or future reporting periods and on foreseeable future transactions.

2 Summary of significant accounting policies (continued)

2.2 Subsidiaries

2.2.1 Consolidation

A subsidiary is an entity (including a structured 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. Subsidiaries are consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

(a) Business combinations

The Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair values of the assets transferred, the liabilities incurred to the former owners of the acquiree and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date.

The Group recognises any non-controlling interest in the acquiree on an acquisition-by-acquisition basis. Non-controlling interests in the acquiree that are present ownership interests and entitle their holders to a proportionate share of the entity’s net assets in the event of liquidation are measured at either fair value or the present ownership interests’ proportionate share in the recognised amounts of the acquiree’s identifiable net assets. All other components of non-controlling interests are measured at their acquisition date fair value, unless another measurement basis is required by IFRS.

Acquisition-related costs are expensed as incurred.

If the business combination is achieved in stages, the acquisition date carrying value of the acquirer’s previously held equity interest in the acquiree is re-measured to fair value at the acquisition date; any gains or losses arising from such re-measurement are recognized in profit or loss.

Any contingent consideration to be transferred by the Group is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration that is deemed to be an asset or liability is recognized in accordance with IAS 39 in profit or loss. Contingent consideration that is classified as equity is not remeasured, and its subsequent settlement is accounted for within equity.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired, is recorded as goodwill. If the total consideration transferred, non-controlling interest recognized and previously held interest measured is less than the fair value of the identifiable net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

Intra-Group 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. When necessary, amounts reported by subsidiaries have been adjusted to conform with the Group’s accounting policies.

(b) Changes in ownership interests in subsidiaries without change of control

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions – that is, as transactions with the owners of the subsidiary in their capacity as owners. The difference between fair value of any consideration paid and the relevant share acquired of the carrying amount of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

For the year ended 31 December 2017

2 Summary of significant accounting policies (continued)

2.2 Subsidiaries (continued)

2.2.1 Consolidation (continued)

(c) Disposal of subsidiaries

When the Group ceases to have control, any retained interest in the entity is re-measured to its fair value at the date when control is lost, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequent accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Group had directly disposed of the related assets or liabilities. It means the amounts previously recognized in other comprehensive income are reclassified to profit or loss or transferred to another category of equity as specified by applicable IFRSs.

2.2.2 Separate financial statements

Investments in subsidiaries are accounted for at cost less impairment. Cost includes direct attributable costs of investment. The results of subsidiaries are accounted for by the Company on the basis of dividend received and receivable.

Impairment testing of the investments in subsidiaries is required upon receiving a dividend from these investments if the dividend exceeds the total comprehensive income of the subsidiary in the period the dividend is declared or if the carrying amount of the investment in the separate financial statements exceeds the carrying amount in the consolidated financial statements of the investee’s net assets including goodwill.

Investments in joint ventures and associates are accounted for using the equity method of accounting.

2.3 Associates

An associate is an entity over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting. Under the equity method, the investment is initially recognized at cost, and the carrying amount is increased or decreased to recognize the investor’s share of the profit or loss of the investee after the date of acquisition. The Group’s investments in associates include goodwill identified on acquisition. Upon the acquisition of the ownership interest in an associate, any difference between the cost of the associate and the Group’s share of the net fair value of the associate’s identifiable assets and liabilities is accounted for as goodwill.

If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income is reclassified to profit or loss where appropriate.

The Group’s share of post-acquisition profit or loss is recognized in the income statement, and its share of post-acquisition movements in other comprehensive income is recognized in other comprehensive income with a corresponding adjustment to the carrying amount of the investment. When the Group’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Group does not recognize further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.

The Group determines at each reporting date whether there is any objective evidence that the investment in the associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognizes the amount adjacent to “share of profit of investments accounted for using the equity method” in the income statement.

For the year ended 31 December 2017

2 Summary of significant accounting policies (continued)

2.3 Associates (continued)

Profits and losses resulting from upstream and downstream transactions between the Group and its associates are recognized in the Group’s financial statements only to the extent of unrelated investor’s interests in the associates. Unrealized losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.

Gain or losses on dilution of equity interest in associates are recognised in the income statement.

2.4 Joint arrangements

The Group has applied IFRS 11 to all joint arrangements. Under IFRS 11, investments in joint arrangements are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Group has assessed the nature of its joint arrangements and determined them to be joint ventures. Joint ventures are accounted for using the equity method.

Under the equity method of accounting, interests in joint ventures are 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’s investments in joint ventures include goodwill identified on acquisition. Upon the acquisition of the ownership interest in a joint venture, any difference between the cost of the joint venture and the Group’s share of the net fair value of the joint venture’s identifiable assets and liabilities is accounted for as goodwill. When the Group’s share of losses in a joint venture equals or exceeds its interests in the joint ventures, including any other unsecured receivables, the Group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the joint ventures.

Unrealized gains on transactions between the Group and its joint ventures are eliminated to the extent of the Group’s interest in the joint ventures. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of the joint ventures have been changed where necessary to ensure consistency with the policies adopted by the Group.

2.5 Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Board of Directors that makes strategic decisions.

2.6 Foreign currency translation

(a) Functional and presentation currency

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in RMB, which is the Company’s functional and the Group’s presentation currency.

2 Summary of significant accounting policies (continued)

2.6 Foreign currency translation (continued)

(b) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except when deferred in other comprehensive income as qualifying cash flow hedges and qualifying net investment hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the income statement within “finance income or expenses”. All other foreign exchange gains and losses are presented in the income statement within “Other gains/(losses) – net”.

2.7 Property, plant and equipment

Property, plant and equipment is stated at historical cost less depreciation and impairment losses. Historical cost includes expenditure that is directly attributable to the acquisition of the items.

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. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.

Depreciation on property, plant and equipment is calculated using the straight-line method to allocate their cost to their residual values over their estimated useful lives, as follows:

Buildings	12-40 years
Plant and machinery	12-20 years
Vehicles and other equipment	4-20 years

The assets’ residual values and 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 (Note 2.11).

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized within “Other gains/(losses) – net” in the income statement.

2.8 Construction in progress

Construction in progress represents buildings, various plant and equipment under construction and pending installation, and is stated at cost less government grants that compensate the Company for the cost of construction, and impairment losses. Cost comprises direct costs of construction as well as interest charges, and foreign exchange differences on related borrowed funds to the extent that they are regarded as an adjustment to interest charges, during the period of construction. Construction in progress is transferred to property, plant and equipment when the asset is substantially ready for its intended use. No depreciation is provided in respect of construction in progress.

2.9 Investment properties

Investment properties are properties which are owned or held under a leasehold interest either to earn rental income and/or for capital appreciation.

Investment properties are stated in the balance sheet at cost less accumulated depreciation and impairment losses (Note 2.11). Depreciation is provided over their estimated useful lives on a straight-line basis, after taking into account their estimated residual values. Estimated useful lives of the Group’s investment properties are 30-40 years.

2.10 Lease prepayments and other assets

Lease prepayments and other assets mainly represent prepayments for land use rights and catalysts used in production. These assets are carried at cost less accumulated amortisation and impairment losses. Lease prepayments and other assets are amortised on a straight-line basis over the respective periods of the rights and the estimated useful lives of the catalysts, as follows:

Land use rights	30-50 years
Patents	10-28 years
Catalyst	2-5 years

2.11 Impairment of non-financial assets

Intangible assets that have an indefinite useful life or intangible assets not ready to use are not subject to amortisation and are tested annually for impairment. Assets that are subject to amortisation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at each reporting date.

2.12 Financial assets

2.12.1 Classification

The Group classifies its financial assets in the following categories: at fair value through profit or loss, loans and receivables and available for sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition.

(a) Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets held for trading. A financial asset is classified in this category if acquired principally for the purpose of selling in the short term. Derivatives are also categorised as held for trading unless they are designated as hedges. Assets in this category are classified as current assets if expected to be settled within 12 months; otherwise, they are classified as non-current.

(b) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for the amounts that are settled or expected to be settled more than 12 months after the end of the reporting period. These are classified as non-current assets. The Group’s loans and receivables comprise “trade receivables, bills receivable and other receivables” and “cash and cash equivalents” in the balance sheet (Note 2.17 and 2.18).

(c) Available-for-sale financial assets

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless the investment matures or management intends to dispose of it within 12 months of the end of the reporting period.

2.12.2 Recognition and measurement

Regular way purchases and sales of financial assets are recognized on the trade-date – the date on which the Group commits to purchase or sell the asset. Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets and financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are subsequently carried at amortised cost using the effective interest method.

Gains or losses arising from changes in the fair value of the “financial liabilities at fair value through profit or loss” category are presented in the income statement within “Other gains/(losses) – net” in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognised in the income statement as part of “other income” when the Group’s right to receive payments is established.

Changes in the fair value of monetary and non-monetary securities classified as available for sale are recognised in “other comprehensive income”.

When securities classified as available for sale are sold or impaired, the accumulated fair value adjustments recognized in equity are included in the income statement as “gains and losses from investment securities”.

Interest on available-for-sale securities calculated using the effective interest method is recognized in the income statement as part of “other income”. Dividends on available-for-sale equity instruments are recognized in the income statement as part of other income when the Group’s right to receive payments is established.

2.13 Offsetting financial instruments

Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the company or the counterparty.

2.14 Impairment of financial assets

(a) Assets carried at amortised cost

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or group of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a “loss event”) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated.

Evidence of impairment may include indications that the receivables or a group of receivables is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganisation, and where observable data indicate that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.

For loans and receivables category, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is reduced and the amount of the loss is recognized in the consolidated income statement. If a loan has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instrument’s fair value using an observable market price.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the consolidated income statement.

(b) Financial assets classified as available for sale

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired.

For debt securities, if any such evidence exists, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in profit or loss – is reclassified from equity and recognised in profit or loss. If, in a subsequent period, the fair value of a debt instrument classified as available for sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognised in profit or loss, the impairment loss is reversed through the consolidated income statement.

For equity investments, a significant or prolonged decline in the fair value of the security below its cost is also evidence that the assets are impaired. If any such evidence exists, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in profit or loss – is reclassified from equity and recognised in profit or loss. Impairment losses recognised in the consolidated income statement on equity instruments are not reversed through the consolidated income statement.

2 Summary of significant accounting policies (continued)

2.15 Derivative financial instruments

Derivative financial instruments of the Group are foreign exchange forward contracts, which are not designated as hedges.

Derivative financial instruments are initially recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value.

Fair values are obtained from quoted market prices in active markets, including recent market transactions, and through the use of valuation techniques, including discounted cash flow models and options pricing models, as appropriate. All derivatives are carried as assets when fair value is positive and as liabilities when fair value is negative.

The best evidence of the fair value of a derivative at initial recognition is the transaction price (i.e., the fair value of the consideration given or received) unless the fair value of that instrument is evidenced by comparison with other observable current market transactions in the same instrument or based on a valuation technique whose variables include only data from observable markets. When such evidence exists, the Group recognizes profits (losses) on that day.

2.16 Inventories

Inventories are stated at the lower of cost and net realisable value. Cost is determined using the weighted average cost method. The cost of finished goods and work in progress comprises raw materials, direct labour, other direct costs and related production overheads (based on normal operating capacity). It excludes borrowing costs. Net realisable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

2.17 Trade receivables, bills receivable and other receivables

Trade receivables and bills receivable are amounts due from customers for merchandise sold or services performed in the ordinary course of business. If collection of trade receivables, bills receivable and other receivables is expected in one year or less (or in the normal operating cycle of the business if longer), they are classified as current assets. If not, they are presented as non-current assets.

Trade receivables, bills receivable and other receivables are recognized initially at fair value plus transaction costs and subsequently measured at amortised cost using the effective interest method, less allowance for impairment. See Note 2.12.2 for further information about the Group’s accounting for receivables and Note 2.14 for a description of the Group’s impairment policies.

2.18 Cash and cash equivalents

In the consolidated statement of cash flows, cash and cash equivalents include cash in hand, deposits held at call with banks, other short-term highly liquid investments with original maturities of three months or less, and bank overdrafts. In the Group’s balance sheet, bank overdrafts are shown within borrowings in current liabilities.

2.19 Share capital

Ordinary shares are classified as equity.

Incremental costs directly attributable to the issue of new shares are shown in equity as a deduction, net of tax, from the proceeds.

2.20 Safety production fund

Under China’s law and regulation, the Group is required to accrue safety production fund at a certain percentage of the sales of dangerous goods. The fund is earmarked for improving the safety of production. The fund is accrued from retained earnings to other reserves and converted back to retained earnings when used.

2.21 Trade payables and other payables

Trade payables and other payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Trade payables and other payables are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Trade payables and other payables are recognized initially at fair value plus transaction costs and subsequently measured at amortised cost using the effective interest method.

2.22 Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortised cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method.

Fees paid on the establishment of loan facilities are recognized as transaction costs of the loan to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down occurs. To the extent there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalised as a pre-payment for liquidity services and amortised over the period of the facility to which it relates.

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the end of the reporting period.

2.23 Borrowing costs

General and specific 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.

Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalisation.

All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

Borrowing costs include interest expense, finance charges in respect of exchange differences arising from foreign currency borrowings to the extent that they are regarded as an adjustment to interest costs. The exchange gains and losses that are an adjustment to interest costs include the interest rate differential between borrowing costs that would be incurred if the entity had borrowed funds in its functional currency, and the borrowing costs actually incurred on foreign currency borrowings.

2.24 Current and deferred income tax

The tax expense for the period comprises current and deferred tax. Tax is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

(a) 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 countries where the Company’s subsidiaries, associates and joint ventures 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. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

(b) 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, the 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 utilised.

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 liability 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 recognised.

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 utilised.

(c) Offsetting

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.

2.25 Employee benefits

(a) Pension obligations

The PRC employees of the Group are covered by various PRC government-sponsored defined-contribution pension plans under which the employees are entitled to a monthly pension based on certain formulas. The relevant government agencies are responsible for the pension liability to these employees when they retire. The Group contributes on a monthly basis to these pension plans for the employees which are determined at a certain percentage of their salaries. Under these plans, the Group has no obligation for post-retirement benefits beyond the contribution made. Contributions to these plans are expensed as incurred and contributions paid to the defined contribution pension plans for a staff are not available to reduce the Group’s future obligations to such defined-contribution pension plans even if the staff leaves the Group.

(b) Termination benefits

Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Group recognizes termination benefits at the earlier of the following dates: when Group demonstrably commits itself to terminate employment or to provide benefits as a result of voluntary redundancy by having a detailed formal plan which is without realistic possibility of withdrawal. Benefits falling due more than 12 months after the end of the reporting period are discounted to their present value.

2.26 Share-based payment

(a) Equity-settled share-based payment transactions

The Group operates a number of equity-settled, share-based compensation plans, under which the entity receives services from employees as consideration for equity instruments (options) of the Group. The fair value of the employee services received in exchange for the grant of the options is recognised as an expense. The total amount to be expensed is determined by reference to the fair value of the options granted：

• including any market performance conditions such as an entity’s share price;

• excluding the impact of any service and non-market performance vesting conditions such as profitability, sales growth targets and remaining an employee of the entity over a specified time period; and

• including the impact of any non-vesting conditions such as the requirement for employees to save or holding shares for a specified period of time.

At the end of each reporting period, the Group revises its estimates of the number of options that are expected to vest based on the non-marketing performance and service conditions. It recognises the impact of the revision to original estimates, if any, in the income statement, with a corresponding adjustment to equity.

In addition, in some circumstances employees may provide services in advance of the grant date and therefore the grant date fair value is estimated for the purposes of recognising the expense during the period between service commencement period and grant date.

When the options are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs are credited to share capital.

(b) Share-based payment transactions among Group entities

The grant by the Company of options over its equity instruments to the employees of subsidiary undertakings in the Group is treated as a capital contribution. The fair value of employee services received, measured by reference to the grant date fair value, is recognised over the vesting period as an increase to investment in subsidiary undertakings, with a corresponding credit to equity in the parent entity accounts.

2.27 Provisions

Provisions for environmental restoration, restructuring costs and legal claims are recognised 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. Restructuring provisions comprise lease termination penalties and employee termination payments. Provisions are not recognised for future operating losses.

Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognized even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognized as interest expense.

2.28 Revenue recognition

Revenue is measured at the fair value of the consideration received or receivable, and represents amounts receivable for goods supplied, stated net of discounts, returns and value added taxes. 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. The Group bases its estimates of return on historical results, taking into consideration the type of customers, the type of transactions and the specifics of each arrangement.

(a) Sales of petroleum and chemical products

Revenues associated with the sale of petroleum and chemical products are recognized in the income statement when the significant risks and rewards of ownership have been transferred to the buyer. Revenue excludes value added tax and is after deduction of any trade discounts and returns. No revenue is recognized if there are significant uncertainties regarding recovery of the consideration due to the possible return of goods, or when the amount of revenue and the costs incurred or to be incurred in respect of the transaction cannot be measured reliably.

(b) Pipeline transportation services

Revenues associated with pipeline transportation services are recognized by reference to the stage of completion (that is, when the services are rendered) of the transaction at the end of the reporting period and when the outcome of the transaction can be estimated reliably. The outcome of the transaction can be estimated reliably when the amount of revenue, the costs incurred and the stage of completion can be measured reliably and it is probable that the economic benefits associated with the transaction will flow to the Group.

(c) Rental income

Rental income from investment property is recognized in the income statement on a straight-line basis over the term of the lease.

2.29 Interest income

Interest income is recognized using the effective interest method. When a loan and receivable is impaired, the Group reduces the carrying amount to its recoverable amount, being the estimated future cash flow discounted at the original effective interest rate of the instrument, and continues unwinding the discount as interest income. Interest income on impaired loans and receivables is recognized using the original effective interest rate.

2.30 Dividend income

Dividend income is recognized when the right to receive payment is established.

2.31 Government grants

Grants from the government are recognised at their fair value where there is a reasonable assurance that the grant will be received and the Group will comply with all attached conditions.

Government grants relating to costs are deferred and recognised in the income statement over the period necessary to match them with the costs that they are intended to compensate.

Grants that compensate the Group for the cost of an asset are deducted from the carrying amount of the asset and consequently are effectively recognized in the income statement over the useful life of the asset by way of reduced depreciation expense.

2.32 Leases

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 (net of any incentives received from the lessor) are charged to the income statement on a straight-line basis over the period of the lease.

2.33 Dividend distribution

Dividend distribution to the Company’s shareholders is recognized as a liability in the Group’s financial statements in the period in which the dividends are approved by the Company’s shareholders.

2.34 Research and development costs

Research and development costs comprise all costs that are directly attributable to research and development activities or that can be allocated on a reasonable basis to such activities. Research and development costs are recognized as intangible assets when the following criteria are met:

• it is technically feasible to complete the research and development project so that it will be available for use or sale;

• management intends to complete the research and development project, and use or sell it;

• it can be demonstrated how the research and development project will generate economic benefits;

• there are adequate technical, financial and other resources to complete the development and the ability to use or sell the research and development project; and

• the expenditure attributable to the research and development project during its development phase can be reliably measured.

Other research and development expenditure that do not meet these criteria are recognized as an expense as incurred. Research and development costs previously recognized as an expense are not recognized as an asset in a subsequent period.

3 Financial risk management

3.1 Financial risk factors

The Group’s activities exposed it to a variety of financial risks: market risk (including currency risk, fair value interest rate risk, cash flow interest rate risk and commodity price risk), credit risk and liquidity risk. The Group’s overall risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the Group’s financial performance.

(a) Market risk

(i) Foreign exchange risk

The Group’s major operational activities are carried out in Mainland China and a majority of the transactions are denominated in RMB. Nevertheless the Group is exposed to foreign exchange risk arising from the recognised assets and liabilities (mainly trade payables), and future transactions denominated in foreign currencies, primarily with respect to USD. The Group’s finance department at its headquarter is responsible for monitoring the amount of assets and liabilities, and transactions denominated in foreign currencies to minimise the foreign exchange risk. During the year ended 31 December 2017, the Group did not enter into any forward foreign exchange contracts apart from a subsidiary, China Jinshan Associated Trading Corporation, which uses forward foreign exchange contracts to mitigate its exposure to foreign exchange risk. The forward contracts China Jinshan Associated Trading Corporation used are not designed as hedging instrument (2016: the Group did not enter into any forward foreign exchange contracts).

As at 31 December 2017, if the foreign currencies had weakened/strengthened by 5% against RMB with all other variables held constant, the Group’s net profit for the year would have been RMB 25,101 thousands increased/decreased as a result of foreign exchange gains/losses on translation of foreign currencies denominated trade payables (31 December 2016: RMB 23,139 thousands, 31 December 2015: RMB 3,605 thousands).

(ii) Cash flow and fair value interest rate risk

The Group’s interest rate risk arises from short-term interest bearing borrowings. Borrowings obtained at variable rates expose the Group to cash flow interest rate risk. Borrowings obtained at fixed rates expose the Group to fair value interest rate risk. The Group determines the relative proportions of its fixed rate and floating rate contracts depending on the prevailing market conditions. As at 31 December 2017, the Group’s short-term interest bearing borrowings denominated with floating rates amounted to RMB 606,157 thousands, which represented 100% of total borrowing balance (31 December 2016: RMB 46,432 thousands, representing 7% of total borrowing balance).

The Group’s finance department at its headquarter continuously monitors the interest rate position of the Group. Increases in interest rates will increase the cost of new borrowing and the interest expenses with respect to the Group’s outstanding floating rate borrowings, and therefore could have a material adverse effect on the Group’s financial position. The Group makes adjustments timely with reference to the latest market conditions and may enter into interest rate swap agreements to mitigate its exposure to interest rate risk. During the year ended 31 December 2017 and 2016, the Group did not enter into any interest rate swap agreements.

As at 31 December 2017, if interest rates on the floating rate borrowings had risen/fallen by 50 basis points while all other variables had been held constant, the Group’s net profit would have decreased/increased by approximately RMB 2,273 thousands (31 December 2016: RMB 174 thousands), mainly as a result of higher/lower interest expense on floating rate borrowings.

(iii) Commodity price risk

The Group principally engages in processing crude oil into synthetic fibres, resins and plastics, intermediate petrochemicals and petroleum products. The selling price of petroleum products is periodically adjusted by government department based on the market price adjustment mechanism, and generally in connection with the crude oil price. The selling prices of synthetic fibres, resins and plastics and intermediate petrochemicals are market prices. The Group didn’t have any derivative financial instrument such as commodity futures and swaps, therefore the fluctuation of crude oil price could have significant impact on the Group.

3 Financial risk management (continued)

3.1 Financial risk factors (continued)

(b) Credit risk

Credit risk is managed on group basis. It mainly arises from cash at bank, time deposit, trade receivables, other receivables, bills receivable, etc.

The Group expects that there is no significant credit risk associated with cash at bank since they are deposited at state-owned banks and other medium or large size listed banks. Management does not expect that there will be any significant losses from non-performance by these counterparties.

In addition, the Group has policies to limit the credit exposure on trade receivables, other receivables, bills receivable and time deposits. The Group assesses the credit quality of and sets credit limits on its customers by taking into account their financial position, the availability of guarantee from third parties, their credit history and other factors such as current market conditions. The credit history of the customers is regularly monitored by the Group. In respect of customers with a poor credit history, the Group will use written payment reminders, or shorten or cancel credit periods, to ensure the overall credit risk of the Group is limited to a controllable extent.

(c) Liquidity risk

Cash flow forecast is performed by the operating entities of the Group and aggregated by Group finance. Group finance monitors rolling forecasts of the Group’s liquidity requirements to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn committed borrowing facilities from major financial institution so that the Group does not breach borrowing limits or covenants on any of its borrowing facilities to meet the short-term and long-term liquidity requirements.

The liquidity of the Group is primarily dependent on its ability to maintain adequate cash inflow from operations, the renewal of its short-term bank loans and its ability to obtain adequate external financing to support its working capital and meet its debt obligation when they become due. As at 31 December 2017, the Group had credit facilities with several PRC financial institutions which provided the Group to borrow up or to guarantee the issuance of the bills of lading to RMB 21,296,000 thousands, within which amounted to RMB 20,273,466 thousands were unused. The maturity dates of the unused facility amounted to RMB 6,710,000 thousands will be after 31 December 2018 as disclosed in Note 27. Management assessed that all the facilities could be renewed upon the expiration dates.

Surplus cash held by the operating entities over and above balance required for working capital management are transferred to the Group treasury. As at 31 December 2017, the Group held cash and cash equivalents of RMB 7,504,266 thousands (31 December 2016: RMB 5,440,623 thousands) (Note 22) and trade receivables of RMB 386,480 thousands (31 December 2016: RMB 414,944 thousands) (Note 21), that are expected to readily generate cash inflows for managing liquidity risk.

The table below analyses the Group’s financial liabilities into relevant maturity groupings based on the remaining period at the balance sheet date to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

3.2 Capital management

The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

Consistent with others in the industry, the Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings (including “current and non-current borrowings” as shown in the consolidated balance sheet) less cash and cash equivalents. Total capital is calculated as “equity” as shown in the consolidated balance sheet plus net debt.

As cash and cash equivalents exceed total borrowings, which was resulted primarily from the significantly improved profitability and the early repayment of some bank loans before its maturity, there was no net debt as at 31 December 2017 and 2016.

3.3 Fair value estimation

The table below analyses the Group’s financial instruments carried at fair value as at 31 December 2017 by level of the inputs to valuation techniques used to measure fair value. Such inputs are categorised into three levels within a fair value hierarchy as follows:

• The fair value of financial instruments traded in active markets (such as publicly traded derivatives, and trading and available-for-sale securities) is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the group is the current bid price. These instruments are included in level 1.

• The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined using valuation techniques which maximise the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.

• If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3. This is the case for unlisted equity securities.

Recurring fair value measurements As at 31 December 2017	Notes	Level 1 RMB’000		Level 2 RMB’000		Level 3 RMB’000		Total RMB’000
Financial assets
Time deposits with financial institutions			—		2,000,000		—		2,000,000
Total financial assets			—		2,000,000		—		2,000,000
Financial liabilities
Foreign exchange contracts			—		1,516		—		1,516
Total financial liabilities			—		1,516		—		1,516

There were no transfers among level 3 during the year ended 31 December 2017.

Financial assets and financial liabilities not measured at fair value mainly represent bills receivable, trade receivables and other receivables, trade and other payables (except for the staff salaries and welfare payables and taxes payables) and borrowings. As at 31 December 2017, these financial assets are expected to be collected in one year or less and these financial liabilities are due within one year or less. As a result, the carrying amounts of these financial assets and liabilities not measured at fair value are a reasonable approximation of their fair value.

According to the offsetting master arrangements entered into in October 2014 between the Company and its related party, Shanghai Secco Petrochemical Company Limited (“Shanghai Secco”) and in December 2016 between the Company and its related party, BOC-SPC Gases Company Limited (“BOC”), the relevant financial assets and liabilities of each operating agreement between the Company and Shanghai Secco and those between the Company and BOC, are settled on a net basis as at 31 December 2016. No such agreement or offset settlement was identified as at 31 December 2017.

4 Critical accounting estimates and assumptions

Estimates and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.

4 Critical accounting estimates and assumptions (continued)

(a) Net realisable value (“NRV”) of inventories

The NRV is determined based on the estimated selling prices less the estimated costs to completion, if relevant, other costs necessary to make the sale, and the related taxes. Determination of estimated selling prices requires significant management judgement, taking into consideration of historical selling prices and future market trend. If the actual selling prices were to be lower or the costs of completion were to be higher than estimated, the actual allowance for diminution in value of inventories could be higher than the estimate.

(b) Impairments for non-financial assets

In determining the value in use, expected cash flows generated by the non-financial assets or the cash-generating unit are discounted to their present value. Management uses all readily available information in determining an amount that is a reasonable approximation of recoverable amount, including estimates based on reasonable and supportable assumptions and projections of sale volume, selling price and amount of operating costs.

(c) Useful life and residual value of property, plant and equipment

Property, plant and equipment, are depreciated on a straight-line basis over the estimated useful lives of the assets, after taking into account the estimated residual value. Management reviews the estimated useful lives of the assets annually in order to determine the amount of depreciation expense to be recorded during any reporting period. The useful lives are based on the Group’s historical experience with similar assets, taking into account anticipated technological changes. The depreciation expense for future periods is adjusted if there are significant changes from previous estimates.

(d) Recognition of deferred tax assets

There are many transactions and events for which the ultimate tax determination is uncertain during the ordinary course of business. Significant judgment is required from the Group in determining the provision for income taxes. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

Deferred tax assets are recognised in respect of temporary deductible differences and the carryforward of unused tax losses. Management recognises deferred tax assets only to the extent that it is probable that future taxable profit will be available against the assets which can be realised or utilised. At the end of each reporting period, management assesses whether previously unrecognised deferred tax assets should be recognized. The Group recognises a previously unrecognised deferred tax asset to the extent that it is probable that future taxable profit will allow the deferred tax asset to be utilised. In addition, management assesses the carrying amount of deferred tax assets that are recognised at the end of each reporting period. The Group reduces the carrying amount of a deferred tax asset to the extent that it is no longer probable that sufficient taxable profit will be available for the deferred tax asset to be utilised.

In making the assessment of whether it is probable the Group will realize or utilise the deferred tax assets, management primarily relies on the generation of future taxable income to support the recognition of deferred tax assets. In order to fully utilize the deferred tax assets recognized at 31 December 2017, the Group would need to generate future taxable income of at least RMB 477 million. Based on estimated forecast and historical experience, management believes that it is probable that the Group will generate sufficient taxable income to utilize the deferred tax assets.

5 Segment information

The Group manages its business by divisions, which are organized by business lines. In view of the fact that the Company and its subsidiaries operate mainly in the PRC, no geographical segment information is presented.

In a manner consistent with the way in which information is reported internally to the Group’s chief operating decision maker, Board of Directors, for the purposes of resource allocation and performance assessment, the Group has identified the following five reportable segments. No operating segments have been aggregated to form the following reportable segments.

Segment results, assets and liabilities include items directly attributable to a segment as well as those that can be allocated on a reasonable basis. Unallocated items mainly comprise investments accounted for using the equity method, deferred income tax assets, cash and cash equivalents,time deposits,entrusted lending and incomes relating to these assets (such as share of profit of investments accounted for using equity method and interest income) and borrowings and interest expenses.

The Group principally operates in five operating segments: synthetic fibres, resins and plastics, intermediate petrochemicals, petroleum products and trading of petrochemical products. Synthetic fibres, resins and plastics, intermediate petrochemicals and petroleum products are produced through intermediate steps from the principal raw material of crude oil. The specific products of each segment are as follows:

(i) The synthetic fibres segment produces primarily polyester, acrylic fibres and carbon fibres, which are mainly used in the textile and apparel industries.

(ii) The resins and plastics segment produces primarily polyester chips, polyethylene resins, polypropylene resins and PVA granules. The polyester chips are used to produce polyester fibres, coating and containers. Polyethylene resins and plastics are used to produce insulated cable, mulching films and moulded products such as housewares and toys. Polypropylene resins are used for films, sheets and moulded products such as housewares, toys, consumer electronics and automobile parts.

(iii) The intermediate petrochemicals segment primarily produces p-xylene, benzene and ethylene oxide. The intermediate petrochemicals produced by the Group are both served as raw materials in the production of other petrochemicals, resins, plastics and synthetic fibres, and sold to external customers.

(iv) The petroleum products segment is equipped with crude oil refinery facilities used to produce qualified refined gasoline, fuel, diesel oil, heavy oil and liquefied petroleum gas, and provide raw materials for the Group’s downstream petrochemical processing facilities.

(v) The trading of petrochemical products segment is primarily engaged in importing and exporting of petrochemical products. The products are sourced from international and domestic suppliers.

(vi) Other operating segments represent the operating segments which do not meet the quantitative threshold for determining reportable segments. These include investment property leasing, service provision and a variety of other commercial activities.

12 Income tax (continued)

The Group recognizes deferred tax assets only to the extent that it is probable that future taxable income will be available against which the assets can be utilised. Based on the level of historical taxable income and projections for future taxable income over the periods which the deferred tax assets will be utilised, management believes that it is probable the Group will realize the benefits of these temporary differences for which deferred tax assets have been recognized.

(iii) Deferred tax assets not recognized

As at 31 December 2017, certain subsidiaries of the Company did not recognise the deferred tax assets in respect of the impairment losses on property, plant and equipment amounting to RMB 486,592 thousands and provision for inventories amounting to RMB 47,582 thousands (31 December 2016: RMB 456,623 thousands and RMB 46,190 thousands respectively), because it was not probable that the related tax benefit would be realized.

As at 31 December 2017, certain subsidiaries of the Company did not recognize the deferred tax assets of RMB 607,753 thousands (31 December 2016: RMB 432,634 thousands) in respect of unused tax losses carried forward for PRC income tax purpose because it was not probable that the related tax benefit would be realized.

13 Earnings per share

(a) Basic

Basic earnings per share is calculated by dividing the profit attributable to owners of the Company by the weighted average number of ordinary shares in issue during the year.

	2015		2016		2017
	RMB’000		RMB’000		RMB’000
Net profit attributable to owners of the Company		3,274,308		5,968,466		6,143,222
Weighted average number of ordinary shares in issue(thousands of shares)		10,800,000		10,800,000		10,803,690
Basic earnings per share(RMB per share)		RMB 0.303		RMB 0.553		RMB 0.569
Basic earnings per ADS(RMB per ADS)		RMB 30.318		RMB 55.264		RMB 56.862

(b) Diluted

Diluted earnings per share is calculated by adjusting the weighted average number of ordinary shares outstanding to assume conversion of all dilutive potential ordinary shares.

The Company has dilutive potential ordinary shares from share options. The number of shares that would have been issued assuming the exercise of the share options less the number of shares that could have been issued at fair value (determined as the average market price per the Company’s A share for year ended 31 December 2017) for the same total proceeds is the number of shares issued for no consideration. The resulting number of shares issued for no consideration is included in the weighted average number of ordinary shares as the denominator for calculating diluted earnings per share.

The calculation of the diluted earnings per share for year ended 31 December 2015,2016 and 2017 was shown as:

	2015		2016		2017
	RMB’000		RMB’000		RMB’000

26 Share-based payments

Pursuant to the resolution of the fifth meeting of the eighth session of the Board of Directors of the Company on 6 January 2015, the proposal regarding the list of participants and the number of share options under the share option incentive scheme was approved.

According to the Company’s share option incentive scheme, the grant date of share options was 6 January 2015, and there were a total of 38,760 thousand share options granted to 214 participants (0.359% of the total ordinary share capital issued). Each share option has a right to purchase an ordinary A share listed in PRC on vesting date at the exercise price under vesting conditions. The options were divided by three tranches of 40%, 30% and 30% of the total share options granted, respectively. Each tranche had independent vesting conditions relevant to year 2015, 2016 and 2017, respectively, which were listed as following:

• weighted average rate of return on equity of the Group should be no less than 9% for 2015, 9.5% for 2016 and 10% for 2017 in respect to the three tranche;

• for each year of 2015, 2016 and 2017, the compound annual growth rate in net profit based on the net profit of 2013 should achieve 5%;

• for each year of 2015, 2016 and 2017, proportion of the main business revenue in the total revenue should be no less than 99%;

• for each year of 2015, 2016 and 2017, each of the above three conditions should be no lower than the 75% level of peer companies; and

• achieving the target budget set by the Sinopec Corp. in 2015, 2016 and 2017, respectively.

The participant should serve the Group at the required position from the grant date. Exercisable amount of each tranche depended on the time for which the participant served the Group during each year of 2015, 2016 and 2017. Upon the fulfilment of relevant vesting conditions, the share options of each tranche shall become exercisable at its exercisable date.

The fair value of the employee services received in exchange for the grant of this equity-settled, share-based compensation plan is recognised as an expense on a straight-line basis over the vesting period of each tranche. The total amount to be expensed is determined by reference to the fair value of the options granted excluding the impact of any service and non-market performance vesting conditions. When the options are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs are credited to share capital and share premium.

As at the grand date, the exercise price of each option was RMB 4.2. During the vesting period, the exercise price would be adjusted according to the declaration of dividends or any changes of total shares. As at 31 December 2017, the outstanding share options of each tranche, their exercisable date and exercise price are as follows.

General information [abstract]

General information

1 General information

Sinopec Shanghai Petrochemical Company Limited (“the Company”), formerly Shanghai Petrochemical Company Limited, was established in the People’s Republic of China (“the PRC”) on 29 June 1993 as a joint stock limited company to hold the assets and liabilities of the production divisions and certain other units of Shanghai Petrochemical Complex (“SPC”), a state-owned enterprise. The Company was under the direct supervision of China Petrochemical Corporation (“Sinopec Group”) at that time.

The Company completed its initial public offerings in 1993. Its shares were listed on the Stock Exchange of Hong Kong Limited (“H shares”) and the New York Stock Exchange in the form of American Depositary Shares (“ADS”) on 26 July 1993, and were also listed on the Shanghai Stock Exchange (“ordinary A shares”) on 8 November 1993.

Sinopec Group completed its reorganisation on 25 February 2000. After the reorganisation, China Petroleum & Chemical Corporation (“Sinopec Corp.”) was established. As part of the reorganisation, Sinopec Group transferred its 4,000,000,000 of the Company’s state-owned legal shares, which represented 55.56 percent of the issued share capital of the Company, to Sinopec Corp.

The Company changed its name to Sinopec Shanghai Petrochemical Company Limited on 12 October 2000, and Sinopec Corp. was the largest shareholder of the Company.

Pursuant to the “Approval on matters relating to the Share Segregation Reform of Sinopec Shanghai Petrochemical Company Limited” issued by the State-owned Assets Supervision and Administration Commission of the State Council (State Owned Property [2013] No.443), a General Meeting of A share shareholders was held on 8 July 2013 and passed the resolution of “Share Segregation Reform of Sinopec Shanghai Petrochemical Company Limited (Amendment)” (“the Share Segregation Reform Resolution”) which was published by the Company on Shanghai Stock Exchange (“SSE”) website on 20 June 2013.

According to the Share Segregation Reform Resolution, the controlling shareholder of the Company, Sinopec Corp., offered shareholders of circulating A shares 5 shares for every 10 circulating A shares they held on 16 August 2013, aggregating 360,000,000 A shares, for the purpose of obtaining the listing rights of its non-circulating shares in the A Shares market. From 20 August 2013 (“the circulation date”), all the Company’s non-circulating A shares have been granted circulating rights on Shanghai Stock Exchange (“SSE”). As part of the restricted conditions, Sinopec Corp. committed that all the 3,640,000,000 A shares held were not allowed to be traded on SSE or transferred within 12 months from the circulation date (“the restriction period”). After the restriction period, Sinopec Corp. can only sell no more than 5 and 10 percent of its total shares within 12 and 24 months, respectively. The former 150,000,000 non-circulating A shares held by social legal persons were also prohibited to be traded on SSE or transferred within 12 months from the circulation date. Meanwhile, Sinopec Corp. also committed in the Share Segregation Reform Resolution that a scheme of converting surplus to share capital (no less than 4 shares for every 10 shares) will be proposed on the board of directors and shareholders meetings within 6 months after the circulation date.

The 15th meeting of the 7th term of Board of Directors was held on 28 August 2013 and the Company proposed and passed a resolution regarding interim cash dividend for the first half of 2013 and the conversion of share premium and surplus reserve to share capital. The resolution included a distribution of 5 shares and a cash dividend distribution of RMB 0.5 (tax included) for every 10 shares based on the 7,200,000 thousands ordinary shares as at 30 June 2013. Among the 5 shares distributed, 3.36 shares were converted from share premium of RMB 2,420,841 thousands and 1.64 shares were converted from surplus reserves of RMB 1,179,159 thousands. The resolution were approved by the extraordinary general meeting of shareholders, A share class shareholders meeting and H share class shareholders meeting on 22 October 2013, respectively.

The first tranche of the Share Option Incentive Scheme was exercised on 29 August 2017, and the Company received cash payment of RMB 54,580 thousands from 199 grantees. As a result, ordinary A shares of 14,177 thousands were registered on 27 September 2017.

As at 31 December 2017, total shares of the Company were 10,814,177 thousands (31 December 2016: 10,800,000 thousands).

The Company and its subsidiaries (“the Group”) are principally engaged in processing crude oil into synthetic fibres, resins and plastics, intermediate petrochemicals and petroleum products.

These consolidated financial statements are presented in thousands of Renminbi Yuan (RMB), unless otherwise stated. These financial statements have been approved for issue by the Board of Directors on 27 April 2018.

Summary of Significant Accounting Policies

Summary of significant accounting policies [abstract]

Summary of significant accounting policies

2 Summary of significant accounting policies

The principal accounting policies applied in the preparation of these consolidated financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

2.1 Basis of preparation

The consolidated financial statements of the Group have been prepared in accordance with all applicable International Financial Reporting Standards (“IFRS”) as issued by International Accounting Standards Board (“IASB”). The consolidated financial statements have been prepared under the historical cost convention, as modified by the revaluation of financial assets and financial liabilities at fair value through profit or loss, which are carried at fair value.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 4.

2.1.1 Changes in accounting policy and disclosures

(a) New and amended standards adopted by the Group

The following new and amended standards and interpretations are effective for the financial year beginning on 1 January 2017. None of them has a material impact on the Group.

Amendments to IAS 7, ‘Statement of cash flows’

Amendments to IAS 12, ‘Income taxes’

Amendment to IFRS 12, ‘Disclosure of interest in other entities’

There are no other amended standards or interpretations that are effective for the first time for this annual period that could be expected to have a material impact on the Group.

(b) New standards and interpretations not yet adopted

Certain new accounting standards and interpretations have been published that are not mandatory for 31 December 2017 reporting periods and have not been early adopted by the Group. The Group’s assessment of the impact of these new standards and interpretations is set out below.

IFRS 9, ‘Financial instruments’, addresses the classification, measurement and derecognition of financial assets and financial liabilities. The complete version of IFRS 9 was issued in July 2014. It replaces the whole of IAS 39. IFRS 9 introduces a new model for the recognition of impairment losses – the expected credit losses (ECL) model, which constitutes a change from the incurred losses model in IAS 39. IFRS 9 applies to all hedging relationships, with the exception of portfolio fair value hedges of interest rate risk. The new guidance better aligns hedge accounting with the risk management activities of an entity and provides relief from the more “rule-based” approach of IAS 39. IFRS 9 is effective for annual periods beginning on or after 1 January 2018 and the Group will apply the new rules retrospectively from 1 January 2018, with the practical expedients permitted under the standard. It is not expected to have any significant impact on the consolidated financial statement of the Group.

IFRS 15, ‘Revenue from contracts with customers’, establishes a comprehensive framework for determining when to recognize revenue and how much revenue to recognise through a 5-step approach. IFRS 15 provides specific guidance on capitalisation of contract cost and licence arrangements. It also includes a cohesive set of disclosure requirements about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. The core principle is that a company should recognise revenue to depict the transfer of promised goods or services to the customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. IFRS 15 replaces the previous revenue standards: IAS 18 ‘Revenue’ and IAS 11 ‘Construction Contracts’ and the related Interpretations on revenue recognition: IFRIC 13 ‘Customer Loyalty Programmes’, IFRIC 15 ‘Agreements for the Construction of Real Estate’, IFRIC 18 ‘Transfers of Assets from Customers’ and SIC-31 ‘Revenue—Barter Transactions Involving Advertising Services’. IFRS 15 is effective for annual reporting periods beginning on or after 1 January 2018.

The application of HKFRS 15 may further result in the identification of separate performance obligations in relation to shipping service derived from oversea trading sales of the Group which could affect the timing of the recognition of revenue, from point in time to overtime going forward. The standard permits either a full retrospective or a modified retrospective approach for the adoption. Mandatory for financial years commencing on or after 1 January 2018. The Group intends to adopt the standard using the modified retrospective approach which means that the cumulative impact of the adoption will be recognised in retained earnings as of 1 January 2018 and that comparatives will not be restated.

IFRS 16, ‘Leases’, provides updated guidance on the definition of leases, and the guidance on the combination and separation of contracts. Under IFRS 16, a contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. IFRS 16 requires lessees to recognise lease liability reflecting future lease payments and a ‘right-of-use-asset’ for almost all lease contracts, with an exemption for certain short-term leases and leases of low value assets. The lessors accounting stays almost the same as under IAS 17 ‘Leases’. IFRS 16 is effective for annual reporting periods beginning on or after 1 January 2019.

The standard will affect primarily the accounting for the Group’s operating leases when the Group is as the leasee in those leases. As at the reporting date, the Group has non-cancellable operating lease commitments, as disclosed in Note 33(b). The Group is still evaluating the effects of the new standard on the other lease commitments with the lease term greater than one year and intends to apply the simplified transition approach and will not restate comparative amounts for the year prior to first adoption. At this stage, the Group does not intend to adopt the standard before its effective date.

There are no other standards that are not yet effective and that would be expected to have a material impact on the Group in the current or future reporting periods and on foreseeable future transactions.

2.2 Subsidiaries

2.2.1 Consolidation

A subsidiary is an entity (including a structured 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. Subsidiaries are consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

(a) Business combinations

The Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair values of the assets transferred, the liabilities incurred to the former owners of the acquiree and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date.

The Group recognises any non-controlling interest in the acquiree on an acquisition-by-acquisition basis. Non-controlling interests in the acquiree that are present ownership interests and entitle their holders to a proportionate share of the entity’s net assets in the event of liquidation are measured at either fair value or the present ownership interests’ proportionate share in the recognised amounts of the acquiree’s identifiable net assets. All other components of non-controlling interests are measured at their acquisition date fair value, unless another measurement basis is required by IFRS.

Acquisition-related costs are expensed as incurred.

If the business combination is achieved in stages, the acquisition date carrying value of the acquirer’s previously held equity interest in the acquiree is re-measured to fair value at the acquisition date; any gains or losses arising from such re-measurement are recognized in profit or loss.

Any contingent consideration to be transferred by the Group is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration that is deemed to be an asset or liability is recognized in accordance with IAS 39 in profit or loss. Contingent consideration that is classified as equity is not remeasured, and its subsequent settlement is accounted for within equity.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired, is recorded as goodwill. If the total consideration transferred, non-controlling interest recognized and previously held interest measured is less than the fair value of the identifiable net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

Intra-Group 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. When necessary, amounts reported by subsidiaries have been adjusted to conform with the Group’s accounting policies.

(b) Changes in ownership interests in subsidiaries without change of control

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions – that is, as transactions with the owners of the subsidiary in their capacity as owners. The difference between fair value of any consideration paid and the relevant share acquired of the carrying amount of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

(c) Disposal of subsidiaries

When the Group ceases to have control, any retained interest in the entity is re-measured to its fair value at the date when control is lost, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequent accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Group had directly disposed of the related assets or liabilities. It means the amounts previously recognized in other comprehensive income are reclassified to profit or loss or transferred to another category of equity as specified by applicable IFRSs.

2.2.2 Separate financial statements

Investments in subsidiaries are accounted for at cost less impairment. Cost includes direct attributable costs of investment. The results of subsidiaries are accounted for by the Company on the basis of dividend received and receivable.

Impairment testing of the investments in subsidiaries is required upon receiving a dividend from these investments if the dividend exceeds the total comprehensive income of the subsidiary in the period the dividend is declared or if the carrying amount of the investment in the separate financial statements exceeds the carrying amount in the consolidated financial statements of the investee’s net assets including goodwill.

Investments in joint ventures and associates are accounted for using the equity method of accounting.

2.3 Associates

An associate is an entity over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting. Under the equity method, the investment is initially recognized at cost, and the carrying amount is increased or decreased to recognize the investor’s share of the profit or loss of the investee after the date of acquisition. The Group’s investments in associates include goodwill identified on acquisition. Upon the acquisition of the ownership interest in an associate, any difference between the cost of the associate and the Group’s share of the net fair value of the associate’s identifiable assets and liabilities is accounted for as goodwill.

If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income is reclassified to profit or loss where appropriate.

The Group’s share of post-acquisition profit or loss is recognized in the income statement, and its share of post-acquisition movements in other comprehensive income is recognized in other comprehensive income with a corresponding adjustment to the carrying amount of the investment. When the Group’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Group does not recognize further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.

The Group determines at each reporting date whether there is any objective evidence that the investment in the associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognizes the amount adjacent to “share of profit of investments accounted for using the equity method” in the income statement.

Profits and losses resulting from upstream and downstream transactions between the Group and its associates are recognized in the Group’s financial statements only to the extent of unrelated investor’s interests in the associates. Unrealized losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.

Gain or losses on dilution of equity interest in associates are recognised in the income statement.

2.4 Joint arrangements

The Group has applied IFRS 11 to all joint arrangements. Under IFRS 11, investments in joint arrangements are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Group has assessed the nature of its joint arrangements and determined them to be joint ventures. Joint ventures are accounted for using the equity method.

Under the equity method of accounting, interests in joint ventures are 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’s investments in joint ventures include goodwill identified on acquisition. Upon the acquisition of the ownership interest in a joint venture, any difference between the cost of the joint venture and the Group’s share of the net fair value of the joint venture’s identifiable assets and liabilities is accounted for as goodwill. When the Group’s share of losses in a joint venture equals or exceeds its interests in the joint ventures, including any other unsecured receivables, the Group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the joint ventures.

Unrealized gains on transactions between the Group and its joint ventures are eliminated to the extent of the Group’s interest in the joint ventures. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of the joint ventures have been changed where necessary to ensure consistency with the policies adopted by the Group.

2.5 Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Board of Directors that makes strategic decisions.

2.6 Foreign currency translation

(a) Functional and presentation currency

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in RMB, which is the Company’s functional and the Group’s presentation currency.

(b) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except when deferred in other comprehensive income as qualifying cash flow hedges and qualifying net investment hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the income statement within “finance income or expenses”. All other foreign exchange gains and losses are presented in the income statement within “Other gains/(losses) – net”.

2.7 Property, plant and equipment

Property, plant and equipment is stated at historical cost less depreciation and impairment losses. Historical cost includes expenditure that is directly attributable to the acquisition of the items.

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. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.

Depreciation on property, plant and equipment is calculated using the straight-line method to allocate their cost to their residual values over their estimated useful lives, as follows:

Buildings	12-40 years
Plant and machinery	12-20 years
Vehicles and other equipment	4-20 years

The assets’ residual values and 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 (Note 2.11).

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized within “Other gains/(losses) – net” in the income statement.

2.8 Construction in progress

Construction in progress represents buildings, various plant and equipment under construction and pending installation, and is stated at cost less government grants that compensate the Company for the cost of construction, and impairment losses. Cost comprises direct costs of construction as well as interest charges, and foreign exchange differences on related borrowed funds to the extent that they are regarded as an adjustment to interest charges, during the period of construction. Construction in progress is transferred to property, plant and equipment when the asset is substantially ready for its intended use. No depreciation is provided in respect of construction in progress.

2.9 Investment properties

Investment properties are properties which are owned or held under a leasehold interest either to earn rental income and/or for capital appreciation.

Investment properties are stated in the balance sheet at cost less accumulated depreciation and impairment losses (Note 2.11). Depreciation is provided over their estimated useful lives on a straight-line basis, after taking into account their estimated residual values. Estimated useful lives of the Group’s investment properties are 30-40 years.

2.10 Lease prepayments and other assets

Lease prepayments and other assets mainly represent prepayments for land use rights and catalysts used in production. These assets are carried at cost less accumulated amortisation and impairment losses. Lease prepayments and other assets are amortised on a straight-line basis over the respective periods of the rights and the estimated useful lives of the catalysts, as follows:

Land use rights	30-50 years
Patents	10-28 years
Catalyst	2-5 years

2.11 Impairment of non-financial assets

Intangible assets that have an indefinite useful life or intangible assets not ready to use are not subject to amortisation and are tested annually for impairment. Assets that are subject to amortisation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at each reporting date.

2.12 Financial assets

2.12.1 Classification

The Group classifies its financial assets in the following categories: at fair value through profit or loss, loans and receivables and available for sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition.

(a) Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets held for trading. A financial asset is classified in this category if acquired principally for the purpose of selling in the short term. Derivatives are also categorised as held for trading unless they are designated as hedges. Assets in this category are classified as current assets if expected to be settled within 12 months; otherwise, they are classified as non-current.

(b) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for the amounts that are settled or expected to be settled more than 12 months after the end of the reporting period. These are classified as non-current assets. The Group’s loans and receivables comprise “trade receivables, bills receivable and other receivables” and “cash and cash equivalents” in the balance sheet (Note 2.17 and 2.18).

(c) Available-for-sale financial assets

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless the investment matures or management intends to dispose of it within 12 months of the end of the reporting period.

2.12.2 Recognition and measurement

Regular way purchases and sales of financial assets are recognized on the trade-date – the date on which the Group commits to purchase or sell the asset. Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets and financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are subsequently carried at amortised cost using the effective interest method.

Gains or losses arising from changes in the fair value of the “financial liabilities at fair value through profit or loss” category are presented in the income statement within “Other gains/(losses) – net” in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognised in the income statement as part of “other income” when the Group’s right to receive payments is established.

Changes in the fair value of monetary and non-monetary securities classified as available for sale are recognised in “other comprehensive income”.

When securities classified as available for sale are sold or impaired, the accumulated fair value adjustments recognized in equity are included in the income statement as “gains and losses from investment securities”.

Interest on available-for-sale securities calculated using the effective interest method is recognized in the income statement as part of “other income”. Dividends on available-for-sale equity instruments are recognized in the income statement as part of other income when the Group’s right to receive payments is established.

2.13 Offsetting financial instruments

Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the company or the counterparty.

2.14 Impairment of financial assets

(a) Assets carried at amortised cost

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or group of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a “loss event”) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated.

Evidence of impairment may include indications that the receivables or a group of receivables is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganisation, and where observable data indicate that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.

For loans and receivables category, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is reduced and the amount of the loss is recognized in the consolidated income statement. If a loan has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instrument’s fair value using an observable market price.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the consolidated income statement.

(b) Financial assets classified as available for sale

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired.

For debt securities, if any such evidence exists, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in profit or loss – is reclassified from equity and recognised in profit or loss. If, in a subsequent period, the fair value of a debt instrument classified as available for sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognised in profit or loss, the impairment loss is reversed through the consolidated income statement.

For equity investments, a significant or prolonged decline in the fair value of the security below its cost is also evidence that the assets are impaired. If any such evidence exists, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in profit or loss – is reclassified from equity and recognised in profit or loss. Impairment losses recognised in the consolidated income statement on equity instruments are not reversed through the consolidated income statement.

2.15 Derivative financial instruments

Derivative financial instruments of the Group are foreign exchange forward contracts, which are not designated as hedges.

Derivative financial instruments are initially recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value.

Fair values are obtained from quoted market prices in active markets, including recent market transactions, and through the use of valuation techniques, including discounted cash flow models and options pricing models, as appropriate. All derivatives are carried as assets when fair value is positive and as liabilities when fair value is negative.

The best evidence of the fair value of a derivative at initial recognition is the transaction price (i.e., the fair value of the consideration given or received) unless the fair value of that instrument is evidenced by comparison with other observable current market transactions in the same instrument or based on a valuation technique whose variables include only data from observable markets. When such evidence exists, the Group recognizes profits (losses) on that day.

2.16 Inventories

Inventories are stated at the lower of cost and net realisable value. Cost is determined using the weighted average cost method. The cost of finished goods and work in progress comprises raw materials, direct labour, other direct costs and related production overheads (based on normal operating capacity). It excludes borrowing costs. Net realisable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

2.17 Trade receivables, bills receivable and other receivables

Trade receivables and bills receivable are amounts due from customers for merchandise sold or services performed in the ordinary course of business. If collection of trade receivables, bills receivable and other receivables is expected in one year or less (or in the normal operating cycle of the business if longer), they are classified as current assets. If not, they are presented as non-current assets.

Trade receivables, bills receivable and other receivables are recognized initially at fair value plus transaction costs and subsequently measured at amortised cost using the effective interest method, less allowance for impairment. See Note 2.12.2 for further information about the Group’s accounting for receivables and Note 2.14 for a description of the Group’s impairment policies.

2.18 Cash and cash equivalents

In the consolidated statement of cash flows, cash and cash equivalents include cash in hand, deposits held at call with banks, other short-term highly liquid investments with original maturities of three months or less, and bank overdrafts. In the Group’s balance sheet, bank overdrafts are shown within borrowings in current liabilities.

2.19 Share capital

Ordinary shares are classified as equity.

Incremental costs directly attributable to the issue of new shares are shown in equity as a deduction, net of tax, from the proceeds.

2.20 Safety production fund

Under China’s law and regulation, the Group is required to accrue safety production fund at a certain percentage of the sales of dangerous goods. The fund is earmarked for improving the safety of production. The fund is accrued from retained earnings to other reserves and converted back to retained earnings when used.

2.21 Trade payables and other payables

Trade payables and other payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Trade payables and other payables are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Trade payables and other payables are recognized initially at fair value plus transaction costs and subsequently measured at amortised cost using the effective interest method.

2.22 Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortised cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method.

Fees paid on the establishment of loan facilities are recognized as transaction costs of the loan to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down occurs. To the extent there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalised as a pre-payment for liquidity services and amortised over the period of the facility to which it relates.

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the end of the reporting period.

2.23 Borrowing costs

General and specific 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.

Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalisation.

All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

Borrowing costs include interest expense, finance charges in respect of exchange differences arising from foreign currency borrowings to the extent that they are regarded as an adjustment to interest costs. The exchange gains and losses that are an adjustment to interest costs include the interest rate differential between borrowing costs that would be incurred if the entity had borrowed funds in its functional currency, and the borrowing costs actually incurred on foreign currency borrowings.

2.24 Current and deferred income tax

The tax expense for the period comprises current and deferred tax. Tax is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

(a) 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 countries where the Company’s subsidiaries, associates and joint ventures 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. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

(b) 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, the 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 utilised.

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 liability 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 recognised.

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 utilised.

(c) Offsetting

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.

2.25 Employee benefits

(a) Pension obligations

The PRC employees of the Group are covered by various PRC government-sponsored defined-contribution pension plans under which the employees are entitled to a monthly pension based on certain formulas. The relevant government agencies are responsible for the pension liability to these employees when they retire. The Group contributes on a monthly basis to these pension plans for the employees which are determined at a certain percentage of their salaries. Under these plans, the Group has no obligation for post-retirement benefits beyond the contribution made. Contributions to these plans are expensed as incurred and contributions paid to the defined contribution pension plans for a staff are not available to reduce the Group’s future obligations to such defined-contribution pension plans even if the staff leaves the Group.

(b) Termination benefits

Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Group recognizes termination benefits at the earlier of the following dates: when Group demonstrably commits itself to terminate employment or to provide benefits as a result of voluntary redundancy by having a detailed formal plan which is without realistic possibility of withdrawal. Benefits falling due more than 12 months after the end of the reporting period are discounted to their present value.

2.26 Share-based payment

(a) Equity-settled share-based payment transactions

The Group operates a number of equity-settled, share-based compensation plans, under which the entity receives services from employees as consideration for equity instruments (options) of the Group. The fair value of the employee services received in exchange for the grant of the options is recognised as an expense. The total amount to be expensed is determined by reference to the fair value of the options granted：

• including any market performance conditions such as an entity’s share price;

• excluding the impact of any service and non-market performance vesting conditions such as profitability, sales growth targets and remaining an employee of the entity over a specified time period; and

• including the impact of any non-vesting conditions such as the requirement for employees to save or holding shares for a specified period of time.

At the end of each reporting period, the Group revises its estimates of the number of options that are expected to vest based on the non-marketing performance and service conditions. It recognises the impact of the revision to original estimates, if any, in the income statement, with a corresponding adjustment to equity.

In addition, in some circumstances employees may provide services in advance of the grant date and therefore the grant date fair value is estimated for the purposes of recognising the expense during the period between service commencement period and grant date.

When the options are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs are credited to share capital.

(b) Share-based payment transactions among Group entities

The grant by the Company of options over its equity instruments to the employees of subsidiary undertakings in the Group is treated as a capital contribution. The fair value of employee services received, measured by reference to the grant date fair value, is recognised over the vesting period as an increase to investment in subsidiary undertakings, with a corresponding credit to equity in the parent entity accounts.

2.27 Provisions

Provisions for environmental restoration, restructuring costs and legal claims are recognised 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. Restructuring provisions comprise lease termination penalties and employee termination payments. Provisions are not recognised for future operating losses.

Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognized even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognized as interest expense.

2.28 Revenue recognition

Revenue is measured at the fair value of the consideration received or receivable, and represents amounts receivable for goods supplied, stated net of discounts, returns and value added taxes. 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. The Group bases its estimates of return on historical results, taking into consideration the type of customers, the type of transactions and the specifics of each arrangement.

(a) Sales of petroleum and chemical products

Revenues associated with the sale of petroleum and chemical products are recognized in the income statement when the significant risks and rewards of ownership have been transferred to the buyer. Revenue excludes value added tax and is after deduction of any trade discounts and returns. No revenue is recognized if there are significant uncertainties regarding recovery of the consideration due to the possible return of goods, or when the amount of revenue and the costs incurred or to be incurred in respect of the transaction cannot be measured reliably.

(b) Pipeline transportation services

Revenues associated with pipeline transportation services are recognized by reference to the stage of completion (that is, when the services are rendered) of the transaction at the end of the reporting period and when the outcome of the transaction can be estimated reliably. The outcome of the transaction can be estimated reliably when the amount of revenue, the costs incurred and the stage of completion can be measured reliably and it is probable that the economic benefits associated with the transaction will flow to the Group.

(c) Rental income

Rental income from investment property is recognized in the income statement on a straight-line basis over the term of the lease.

2.29 Interest income

Interest income is recognized using the effective interest method. When a loan and receivable is impaired, the Group reduces the carrying amount to its recoverable amount, being the estimated future cash flow discounted at the original effective interest rate of the instrument, and continues unwinding the discount as interest income. Interest income on impaired loans and receivables is recognized using the original effective interest rate.

2.30 Dividend income

Dividend income is recognized when the right to receive payment is established.

2.31 Government grants

Grants from the government are recognised at their fair value where there is a reasonable assurance that the grant will be received and the Group will comply with all attached conditions.

Government grants relating to costs are deferred and recognised in the income statement over the period necessary to match them with the costs that they are intended to compensate.

Grants that compensate the Group for the cost of an asset are deducted from the carrying amount of the asset and consequently are effectively recognized in the income statement over the useful life of the asset by way of reduced depreciation expense.

2.32 Leases

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 (net of any incentives received from the lessor) are charged to the income statement on a straight-line basis over the period of the lease.

2.33 Dividend distribution

Dividend distribution to the Company’s shareholders is recognized as a liability in the Group’s financial statements in the period in which the dividends are approved by the Company’s shareholders.

2.34 Research and development costs

Research and development costs comprise all costs that are directly attributable to research and development activities or that can be allocated on a reasonable basis to such activities. Research and development costs are recognized as intangible assets when the following criteria are met:

• it is technically feasible to complete the research and development project so that it will be available for use or sale;

• management intends to complete the research and development project, and use or sell it;

• it can be demonstrated how the research and development project will generate economic benefits;

• there are adequate technical, financial and other resources to complete the development and the ability to use or sell the research and development project; and

• the expenditure attributable to the research and development project during its development phase can be reliably measured.

Other research and development expenditure that do not meet these criteria are recognized as an expense as incurred. Research and development costs previously recognized as an expense are not recognized as an asset in a subsequent period.

2.35 Related parties

(i) A person, or a close member of that person’s family, is related to the Group if that person:

(1) has control or joint control over the Group;

(2) has significant influence over the Group; or

(3) is a member of the key management personnel of the Group or the Group’s parent.

(ii) An entity is related to the Group if any of the following conditions applies:

Financial Risk Management

12 Months Ended

Financial risk management [abstract]

Financial risk management

3 Financial risk management

3.1 Financial risk factors

The Group’s activities exposed it to a variety of financial risks: market risk (including currency risk, fair value interest rate risk, cash flow interest rate risk and commodity price risk), credit risk and liquidity risk. The Group’s overall risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the Group’s financial performance.

(a) Market risk

(i) Foreign exchange risk

The Group’s major operational activities are carried out in Mainland China and a majority of the transactions are denominated in RMB. Nevertheless the Group is exposed to foreign exchange risk arising from the recognised assets and liabilities (mainly trade payables), and future transactions denominated in foreign currencies, primarily with respect to USD. The Group’s finance department at its headquarter is responsible for monitoring the amount of assets and liabilities, and transactions denominated in foreign currencies to minimise the foreign exchange risk. During the year ended 31 December 2017, the Group did not enter into any forward foreign exchange contracts apart from a subsidiary, China Jinshan Associated Trading Corporation, which uses forward foreign exchange contracts to mitigate its exposure to foreign exchange risk. The forward contracts China Jinshan Associated Trading Corporation used are not designed as hedging instrument (2016: the Group did not enter into any forward foreign exchange contracts).

As at 31 December 2017, if the foreign currencies had weakened/strengthened by 5% against RMB with all other variables held constant, the Group’s net profit for the year would have been RMB 25,101 thousands increased/decreased as a result of foreign exchange gains/losses on translation of foreign currencies denominated trade payables (31 December 2016: RMB 23,139 thousands, 31 December 2015: RMB 3,605 thousands).

(ii) Cash flow and fair value interest rate risk

The Group’s interest rate risk arises from short-term interest bearing borrowings. Borrowings obtained at variable rates expose the Group to cash flow interest rate risk. Borrowings obtained at fixed rates expose the Group to fair value interest rate risk. The Group determines the relative proportions of its fixed rate and floating rate contracts depending on the prevailing market conditions. As at 31 December 2017, the Group’s short-term interest bearing borrowings denominated with floating rates amounted to RMB 606,157 thousands, which represented 100% of total borrowing balance (31 December 2016: RMB 46,432 thousands, representing 7% of total borrowing balance).

The Group’s finance department at its headquarter continuously monitors the interest rate position of the Group. Increases in interest rates will increase the cost of new borrowing and the interest expenses with respect to the Group’s outstanding floating rate borrowings, and therefore could have a material adverse effect on the Group’s financial position. The Group makes adjustments timely with reference to the latest market conditions and may enter into interest rate swap agreements to mitigate its exposure to interest rate risk. During the year ended 31 December 2017 and 2016, the Group did not enter into any interest rate swap agreements.

As at 31 December 2017, if interest rates on the floating rate borrowings had risen/fallen by 50 basis points while all other variables had been held constant, the Group’s net profit would have decreased/increased by approximately RMB 2,273 thousands (31 December 2016: RMB 174 thousands), mainly as a result of higher/lower interest expense on floating rate borrowings.

(iii) Commodity price risk

The Group principally engages in processing crude oil into synthetic fibres, resins and plastics, intermediate petrochemicals and petroleum products. The selling price of petroleum products is periodically adjusted by government department based on the market price adjustment mechanism, and generally in connection with the crude oil price. The selling prices of synthetic fibres, resins and plastics and intermediate petrochemicals are market prices. The Group didn’t have any derivative financial instrument such as commodity futures and swaps, therefore the fluctuation of crude oil price could have significant impact on the Group.

(b) Credit risk

Credit risk is managed on group basis. It mainly arises from cash at bank, time deposit, trade receivables, other receivables, bills receivable, etc.

The Group expects that there is no significant credit risk associated with cash at bank since they are deposited at state-owned banks and other medium or large size listed banks. Management does not expect that there will be any significant losses from non-performance by these counterparties.

In addition, the Group has policies to limit the credit exposure on trade receivables, other receivables, bills receivable and time deposits. The Group assesses the credit quality of and sets credit limits on its customers by taking into account their financial position, the availability of guarantee from third parties, their credit history and other factors such as current market conditions. The credit history of the customers is regularly monitored by the Group. In respect of customers with a poor credit history, the Group will use written payment reminders, or shorten or cancel credit periods, to ensure the overall credit risk of the Group is limited to a controllable extent.

(c) Liquidity risk

Cash flow forecast is performed by the operating entities of the Group and aggregated by Group finance. Group finance monitors rolling forecasts of the Group’s liquidity requirements to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn committed borrowing facilities from major financial institution so that the Group does not breach borrowing limits or covenants on any of its borrowing facilities to meet the short-term and long-term liquidity requirements.

The liquidity of the Group is primarily dependent on its ability to maintain adequate cash inflow from operations, the renewal of its short-term bank loans and its ability to obtain adequate external financing to support its working capital and meet its debt obligation when they become due. As at 31 December 2017, the Group had credit facilities with several PRC financial institutions which provided the Group to borrow up or to guarantee the issuance of the bills of lading to RMB 21,296,000 thousands, within which amounted to RMB 20,273,466 thousands were unused. The maturity dates of the unused facility amounted to RMB 6,710,000 thousands will be after 31 December 2018 as disclosed in Note 27. Management assessed that all the facilities could be renewed upon the expiration dates.

Surplus cash held by the operating entities over and above balance required for working capital management are transferred to the Group treasury. As at 31 December 2017, the Group held cash and cash equivalents of RMB 7,504,266 thousands (31 December 2016: RMB 5,440,623 thousands) (Note 22) and trade receivables of RMB 386,480 thousands (31 December 2016: RMB 414,944 thousands) (Note 21), that are expected to readily generate cash inflows for managing liquidity risk.

The table below analyses the Group’s financial liabilities into relevant maturity groupings based on the remaining period at the balance sheet date to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

	Less than 1 year RMB’000		Between 1 and 2 years RMB’000		Between 2 and 5 years RMB’000		Over 5 years RMB’000		Total RMB’000

3.2 Capital management

The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

Consistent with others in the industry, the Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings (including “current and non-current borrowings” as shown in the consolidated balance sheet) less cash and cash equivalents. Total capital is calculated as “equity” as shown in the consolidated balance sheet plus net debt.

As cash and cash equivalents exceed total borrowings, which was resulted primarily from the significantly improved profitability and the early repayment of some bank loans before its maturity, there was no net debt as at 31 December 2017 and 2016.

3.3 Fair value estimation

The table below analyses the Group’s financial instruments carried at fair value as at 31 December 2017 by level of the inputs to valuation techniques used to measure fair value. Such inputs are categorised into three levels within a fair value hierarchy as follows:

• The fair value of financial instruments traded in active markets (such as publicly traded derivatives, and trading and available-for-sale securities) is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the group is the current bid price. These instruments are included in level 1.

• The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined using valuation techniques which maximise the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.

• If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3. This is the case for unlisted equity securities.

Recurring fair value measurements As at 31 December 2017	Notes	Level 1 RMB’000		Level 2 RMB’000		Level 3 RMB’000		Total RMB’000
Financial assets
Time deposits with financial institutions			—		2,000,000		—		2,000,000
Total financial assets			—		2,000,000		—		2,000,000
Financial liabilities
Foreign exchange contracts			—		1,516		—		1,516
Total financial liabilities			—		1,516		—		1,516

There were no transfers among level 3 during the year ended 31 December 2017.

Financial assets and financial liabilities not measured at fair value mainly represent bills receivable, trade receivables and other receivables, trade and other payables (except for the staff salaries and welfare payables and taxes payables) and borrowings. As at 31 December 2017, these financial assets are expected to be collected in one year or less and these financial liabilities are due within one year or less. As a result, the carrying amounts of these financial assets and liabilities not measured at fair value are a reasonable approximation of their fair value.

3.4 Offsetting financial assets and financial liabilities

(a) Financial assets

	As at 31 December 2016 RMB’000
Gross amount of recognised amounts due from related parties		1,403,442
Gross amount of recognised amounts due to related parties set off in the balance sheet		(112,823	)
Net amounts of amounts due from related parties presented in the balance sheet		1,290,619

(b) Financial liabilities

	As at 31 December 2016 RMB’000
Gross amount of recognised amounts due to related parties		3,157,127
Gross amount of recognised amounts due from related parties set off in the balance sheet		(112,823	)
Net amounts of amounts due to related parties presented in the balance sheet		3,044,304

According to the offsetting master arrangements entered into in October 2014 between the Company and its related party, Shanghai Secco Petrochemical Company Limited (“Shanghai Secco”) and in December 2016 between the Company and its related party, BOC-SPC Gases Company Limited (“BOC”), the relevant financial assets and liabilities of each operating agreement between the Company and Shanghai Secco and those between the Company and BOC, are settled on a net basis as at 31 December 2016. No such agreement or offset settlement was identified as at 31 December 2017.

Critical accounting estimates and assumptions

4 Critical accounting estimates and assumptions

Estimates and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.

(a) Net realisable value (“NRV”) of inventories

The NRV is determined based on the estimated selling prices less the estimated costs to completion, if relevant, other costs necessary to make the sale, and the related taxes. Determination of estimated selling prices requires significant management judgement, taking into consideration of historical selling prices and future market trend. If the actual selling prices were to be lower or the costs of completion were to be higher than estimated, the actual allowance for diminution in value of inventories could be higher than the estimate.

(b) Impairments for non-financial assets

In determining the value in use, expected cash flows generated by the non-financial assets or the cash-generating unit are discounted to their present value. Management uses all readily available information in determining an amount that is a reasonable approximation of recoverable amount, including estimates based on reasonable and supportable assumptions and projections of sale volume, selling price and amount of operating costs.

(c) Useful life and residual value of property, plant and equipment

Property, plant and equipment, are depreciated on a straight-line basis over the estimated useful lives of the assets, after taking into account the estimated residual value. Management reviews the estimated useful lives of the assets annually in order to determine the amount of depreciation expense to be recorded during any reporting period. The useful lives are based on the Group’s historical experience with similar assets, taking into account anticipated technological changes. The depreciation expense for future periods is adjusted if there are significant changes from previous estimates.

(d) Recognition of deferred tax assets

There are many transactions and events for which the ultimate tax determination is uncertain during the ordinary course of business. Significant judgment is required from the Group in determining the provision for income taxes. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

Deferred tax assets are recognised in respect of temporary deductible differences and the carryforward of unused tax losses. Management recognises deferred tax assets only to the extent that it is probable that future taxable profit will be available against the assets which can be realised or utilised. At the end of each reporting period, management assesses whether previously unrecognised deferred tax assets should be recognized. The Group recognises a previously unrecognised deferred tax asset to the extent that it is probable that future taxable profit will allow the deferred tax asset to be utilised. In addition, management assesses the carrying amount of deferred tax assets that are recognised at the end of each reporting period. The Group reduces the carrying amount of a deferred tax asset to the extent that it is no longer probable that sufficient taxable profit will be available for the deferred tax asset to be utilised.

In making the assessment of whether it is probable the Group will realize or utilise the deferred tax assets, management primarily relies on the generation of future taxable income to support the recognition of deferred tax assets. In order to fully utilize the deferred tax assets recognized at 31 December 2017, the Group would need to generate future taxable income of at least RMB 477 million. Based on estimated forecast and historical experience, management believes that it is probable that the Group will generate sufficient taxable income to utilize the deferred tax assets.

Segment information [abstract]

Segment information

5 Segment information

The Group manages its business by divisions, which are organized by business lines. In view of the fact that the Company and its subsidiaries operate mainly in the PRC, no geographical segment information is presented.

In a manner consistent with the way in which information is reported internally to the Group’s chief operating decision maker, Board of Directors, for the purposes of resource allocation and performance assessment, the Group has identified the following five reportable segments. No operating segments have been aggregated to form the following reportable segments.

Segment results, assets and liabilities include items directly attributable to a segment as well as those that can be allocated on a reasonable basis. Unallocated items mainly comprise investments accounted for using the equity method, deferred income tax assets, cash and cash equivalents,time deposits,entrusted lending and incomes relating to these assets (such as share of profit of investments accounted for using equity method and interest income) and borrowings and interest expenses.

The Group principally operates in five operating segments: synthetic fibres, resins and plastics, intermediate petrochemicals, petroleum products and trading of petrochemical products. Synthetic fibres, resins and plastics, intermediate petrochemicals and petroleum products are produced through intermediate steps from the principal raw material of crude oil. The specific products of each segment are as follows:

(i) The synthetic fibres segment produces primarily polyester, acrylic fibres and carbon fibres, which are mainly used in the textile and apparel industries.

(ii) The resins and plastics segment produces primarily polyester chips, polyethylene resins, polypropylene resins and PVA granules. The polyester chips are used to produce polyester fibres, coating and containers. Polyethylene resins and plastics are used to produce insulated cable, mulching films and moulded products such as housewares and toys. Polypropylene resins are used for films, sheets and moulded products such as housewares, toys, consumer electronics and automobile parts.

(iii) The intermediate petrochemicals segment primarily produces p-xylene, benzene and ethylene oxide. The intermediate petrochemicals produced by the Group are both served as raw materials in the production of other petrochemicals, resins, plastics and synthetic fibres, and sold to external customers.

(iv) The petroleum products segment is equipped with crude oil refinery facilities used to produce qualified refined gasoline, fuel, diesel oil, heavy oil and liquefied petroleum gas, and provide raw materials for the Group’s downstream petrochemical processing facilities.

(v) The trading of petrochemical products segment is primarily engaged in importing and exporting of petrochemical products. The products are sourced from international and domestic suppliers.

(vi) Other operating segments represent the operating segments which do not meet the quantitative threshold for determining reportable segments. These include investment property leasing, service provision and a variety of other commercial activities.

The Group recognizes deferred tax assets only to the extent that it is probable that future taxable income will be available against which the assets can be utilised. Based on the level of historical taxable income and projections for future taxable income over the periods which the deferred tax assets will be utilised, management believes that it is probable the Group will realize the benefits of these temporary differences for which deferred tax assets have been recognized.

(b) Diluted

Diluted earnings per share is calculated by adjusting the weighted average number of ordinary shares outstanding to assume conversion of all dilutive potential ordinary shares.

The Company has dilutive potential ordinary shares from share options. The number of shares that would have been issued assuming the exercise of the share options less the number of shares that could have been issued at fair value (determined as the average market price per the Company’s A share for year ended 31 December 2017) for the same total proceeds is the number of shares issued for no consideration. The resulting number of shares issued for no consideration is included in the weighted average number of ordinary shares as the denominator for calculating diluted earnings per share.

The calculation of the diluted earnings per share for year ended 31 December 2015,2016 and 2017 was shown as:

	2015		2016		2017

26 Share-based payments

Pursuant to the resolution of the fifth meeting of the eighth session of the Board of Directors of the Company on 6 January 2015, the proposal regarding the list of participants and the number of share options under the share option incentive scheme was approved.

According to the Company’s share option incentive scheme, the grant date of share options was 6 January 2015, and there were a total of 38,760 thousand share options granted to 214 participants (0.359% of the total ordinary share capital issued). Each share option has a right to purchase an ordinary A share listed in PRC on vesting date at the exercise price under vesting conditions. The options were divided by three tranches of 40%, 30% and 30% of the total share options granted, respectively. Each tranche had independent vesting conditions relevant to year 2015, 2016 and 2017, respectively, which were listed as following:

• weighted average rate of return on equity of the Group should be no less than 9% for 2015, 9.5% for 2016 and 10% for 2017 in respect to the three tranche;

• for each year of 2015, 2016 and 2017, the compound annual growth rate in net profit based on the net profit of 2013 should achieve 5%;

• for each year of 2015, 2016 and 2017, proportion of the main business revenue in the total revenue should be no less than 99%;

• for each year of 2015, 2016 and 2017, each of the above three conditions should be no lower than the 75% level of peer companies; and

• achieving the target budget set by the Sinopec Corp. in 2015, 2016 and 2017, respectively.

The participant should serve the Group at the required position from the grant date. Exercisable amount of each tranche depended on the time for which the participant served the Group during each year of 2015, 2016 and 2017. Upon the fulfilment of relevant vesting conditions, the share options of each tranche shall become exercisable at its exercisable date.

The fair value of the employee services received in exchange for the grant of this equity-settled, share-based compensation plan is recognised as an expense on a straight-line basis over the vesting period of each tranche. The total amount to be expensed is determined by reference to the fair value of the options granted excluding the impact of any service and non-market performance vesting conditions. When the options are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs are credited to share capital and share premium.

As at the grand date, the exercise price of each option was RMB 4.2. During the vesting period, the exercise price would be adjusted according to the declaration of dividends or any changes of total shares. As at 31 December 2017, the outstanding share options of each tranche, their exercisable date and exercise price are as follows. These outstanding share options will expire in twelve months after each exercisable date.

Tranche	Exercisable date	Exercise price (per share in RMB)		Outstanding share options
1	6 January 2017		3.85		—
2	6 January 2018		3.85		9,552,250
3	6 January 2019		3.85		9,552,250

The total fair value of share options at the grant date was RMB 65,412 thousands, which has been valued by an external valuation expert using Black-Scholes valuation model with the support from an external valuation expert.

The significant inputs into the model were as follows:

	Granting date
Spot share price	RMB	4.51
Exercise price	RMB	4.20
Expected volatility		41.20%
Maturity (years)		5.00
Risk-free interest rate		3.39%~3.67%
Dividend yield		1.00%

The first tranche of the Share Option Incentive Scheme was exercised on 29 August 2017, and the Company received cash payment of RMB 54,580 thousands from 199 grantees, out of which, RMB 14,177 thousands were in share capital (Note 24) and RMB 40,403 thousands were in reserve as share premium (Note 25).

Share option expenses of RMB 11,276 thousands have been recognised in “Selling and administrative expenses” of the Consolidated Income Statement for the year ended 31 December 2017 (2016: RMB 18,004 thousands, 2015: RMB 22,702 thousands).

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2017

Summary of significant accounting policies [abstract]

Basis of preparation

2.1 Basis of preparation

The consolidated financial statements of the Group have been prepared in accordance with all applicable International Financial Reporting Standards (“IFRS”) as issued by International Accounting Standards Board (“IASB”). The consolidated financial statements have been prepared under the historical cost convention, as modified by the revaluation of financial assets and financial liabilities at fair value through profit or loss, which are carried at fair value.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 4.

2.1.1 Changes in accounting policy and disclosures

(a) New and amended standards adopted by the Group

The following new and amended standards and interpretations are effective for the financial year beginning on 1 January 2017. None of them has a material impact on the Group.

Amendments to IAS 7, ‘Statement of cash flows’

Amendments to IAS 12, ‘Income taxes’

Amendment to IFRS 12, ‘Disclosure of interest in other entities’

There are no other amended standards or interpretations that are effective for the first time for this annual period that could be expected to have a material impact on the Group.

(b) New standards and interpretations not yet adopted

Certain new accounting standards and interpretations have been published that are not mandatory for 31 December 2017 reporting periods and have not been early adopted by the Group. The Group’s assessment of the impact of these new standards and interpretations is set out below.

IFRS 9, ‘Financial instruments’, addresses the classification, measurement and derecognition of financial assets and financial liabilities. The complete version of IFRS 9 was issued in July 2014. It replaces the whole of IAS 39. IFRS 9 introduces a new model for the recognition of impairment losses – the expected credit losses (ECL) model, which constitutes a change from the incurred losses model in IAS 39. IFRS 9 applies to all hedging relationships, with the exception of portfolio fair value hedges of interest rate risk. The new guidance better aligns hedge accounting with the risk management activities of an entity and provides relief from the more “rule-based” approach of IAS 39. IFRS 9 is effective for annual periods beginning on or after 1 January 2018 and the Group will apply the new rules retrospectively from 1 January 2018, with the practical expedients permitted under the standard. It is not expected to have any significant impact on the consolidated financial statement of the Group.

IFRS 15, ‘Revenue from contracts with customers’, establishes a comprehensive framework for determining when to recognize revenue and how much revenue to recognise through a 5-step approach. IFRS 15 provides specific guidance on capitalisation of contract cost and licence arrangements. It also includes a cohesive set of disclosure requirements about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts with customers. The core principle is that a company should recognise revenue to depict the transfer of promised goods or services to the customer in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. IFRS 15 replaces the previous revenue standards: IAS 18 ‘Revenue’ and IAS 11 ‘Construction Contracts’ and the related Interpretations on revenue recognition: IFRIC 13 ‘Customer Loyalty Programmes’, IFRIC 15 ‘Agreements for the Construction of Real Estate’, IFRIC 18 ‘Transfers of Assets from Customers’ and SIC-31 ‘Revenue—Barter Transactions Involving Advertising Services’. IFRS 15 is effective for annual reporting periods beginning on or after 1 January 2018.

The application of HKFRS 15 may further result in the identification of separate performance obligations in relation to shipping service derived from oversea trading sales of the Group which could affect the timing of the recognition of revenue, from point in time to overtime going forward. The standard permits either a full retrospective or a modified retrospective approach for the adoption. Mandatory for financial years commencing on or after 1 January 2018. The Group intends to adopt the standard using the modified retrospective approach which means that the cumulative impact of the adoption will be recognised in retained earnings as of 1 January 2018 and that comparatives will not be restated.

IFRS 16, ‘Leases’, provides updated guidance on the definition of leases, and the guidance on the combination and separation of contracts. Under IFRS 16, a contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. IFRS 16 requires lessees to recognise lease liability reflecting future lease payments and a ‘right-of-use-asset’ for almost all lease contracts, with an exemption for certain short-term leases and leases of low value assets. The lessors accounting stays almost the same as under IAS 17 ‘Leases’. IFRS 16 is effective for annual reporting periods beginning on or after 1 January 2019.

The standard will affect primarily the accounting for the Group’s operating leases when the Group is as the leasee in those leases. As at the reporting date, the Group has non-cancellable operating lease commitments, as disclosed in Note 33(b). The Group is still evaluating the effects of the new standard on the other lease commitments with the lease term greater than one year and intends to apply the simplified transition approach and will not restate comparative amounts for the year prior to first adoption. At this stage, the Group does not intend to adopt the standard before its effective date.

There are no other standards that are not yet effective and that would be expected to have a material impact on the Group in the current or future reporting periods and on foreseeable future transactions.

Subsidiaries

2.2 Subsidiaries

2.2.1 Consolidation

A subsidiary is an entity (including a structured 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. Subsidiaries are consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

(a) Business combinations

The Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair values of the assets transferred, the liabilities incurred to the former owners of the acquiree and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date.

The Group recognises any non-controlling interest in the acquiree on an acquisition-by-acquisition basis. Non-controlling interests in the acquiree that are present ownership interests and entitle their holders to a proportionate share of the entity’s net assets in the event of liquidation are measured at either fair value or the present ownership interests’ proportionate share in the recognised amounts of the acquiree’s identifiable net assets. All other components of non-controlling interests are measured at their acquisition date fair value, unless another measurement basis is required by IFRS.

Acquisition-related costs are expensed as incurred.

If the business combination is achieved in stages, the acquisition date carrying value of the acquirer’s previously held equity interest in the acquiree is re-measured to fair value at the acquisition date; any gains or losses arising from such re-measurement are recognized in profit or loss.

Any contingent consideration to be transferred by the Group is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration that is deemed to be an asset or liability is recognized in accordance with IAS 39 in profit or loss. Contingent consideration that is classified as equity is not remeasured, and its subsequent settlement is accounted for within equity.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired, is recorded as goodwill. If the total consideration transferred, non-controlling interest recognized and previously held interest measured is less than the fair value of the identifiable net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

Intra-Group 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. When necessary, amounts reported by subsidiaries have been adjusted to conform with the Group’s accounting policies.

(b) Changes in ownership interests in subsidiaries without change of control

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions – that is, as transactions with the owners of the subsidiary in their capacity as owners. The difference between fair value of any consideration paid and the relevant share acquired of the carrying amount of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

(c) Disposal of subsidiaries

When the Group ceases to have control, any retained interest in the entity is re-measured to its fair value at the date when control is lost, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequent accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Group had directly disposed of the related assets or liabilities. It means the amounts previously recognized in other comprehensive income are reclassified to profit or loss or transferred to another category of equity as specified by applicable IFRSs.

2.2.2 Separate financial statements

Investments in subsidiaries are accounted for at cost less impairment. Cost includes direct attributable costs of investment. The results of subsidiaries are accounted for by the Company on the basis of dividend received and receivable.

Impairment testing of the investments in subsidiaries is required upon receiving a dividend from these investments if the dividend exceeds the total comprehensive income of the subsidiary in the period the dividend is declared or if the carrying amount of the investment in the separate financial statements exceeds the carrying amount in the consolidated financial statements of the investee’s net assets including goodwill.

Investments in joint ventures and associates are accounted for using the equity method of accounting.

Associates

2.3 Associates

An associate is an entity over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting. Under the equity method, the investment is initially recognized at cost, and the carrying amount is increased or decreased to recognize the investor’s share of the profit or loss of the investee after the date of acquisition. The Group’s investments in associates include goodwill identified on acquisition. Upon the acquisition of the ownership interest in an associate, any difference between the cost of the associate and the Group’s share of the net fair value of the associate’s identifiable assets and liabilities is accounted for as goodwill.

If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income is reclassified to profit or loss where appropriate.

The Group’s share of post-acquisition profit or loss is recognized in the income statement, and its share of post-acquisition movements in other comprehensive income is recognized in other comprehensive income with a corresponding adjustment to the carrying amount of the investment. When the Group’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Group does not recognize further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.

The Group determines at each reporting date whether there is any objective evidence that the investment in the associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognizes the amount adjacent to “share of profit of investments accounted for using the equity method” in the income statement.

Profits and losses resulting from upstream and downstream transactions between the Group and its associates are recognized in the Group’s financial statements only to the extent of unrelated investor’s interests in the associates. Unrealized losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.

Gain or losses on dilution of equity interest in associates are recognised in the income statement.

Joint arrangements

2.4 Joint arrangements

The Group has applied IFRS 11 to all joint arrangements. Under IFRS 11, investments in joint arrangements are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Group has assessed the nature of its joint arrangements and determined them to be joint ventures. Joint ventures are accounted for using the equity method.

Under the equity method of accounting, interests in joint ventures are 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’s investments in joint ventures include goodwill identified on acquisition. Upon the acquisition of the ownership interest in a joint venture, any difference between the cost of the joint venture and the Group’s share of the net fair value of the joint venture’s identifiable assets and liabilities is accounted for as goodwill. When the Group’s share of losses in a joint venture equals or exceeds its interests in the joint ventures, including any other unsecured receivables, the Group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the joint ventures.

Unrealized gains on transactions between the Group and its joint ventures are eliminated to the extent of the Group’s interest in the joint ventures. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of the joint ventures have been changed where necessary to ensure consistency with the policies adopted by the Group.

Segment reporting

2.5 Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Board of Directors that makes strategic decisions.

Foreign currency translation

2.6 Foreign currency translation

(a) Functional and presentation currency

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in RMB, which is the Company’s functional and the Group’s presentation currency.

(b) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except when deferred in other comprehensive income as qualifying cash flow hedges and qualifying net investment hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the income statement within “finance income or expenses”. All other foreign exchange gains and losses are presented in the income statement within “Other gains/(losses) – net”.

Property, plant and equipment

2.7 Property, plant and equipment

Property, plant and equipment is stated at historical cost less depreciation and impairment losses. Historical cost includes expenditure that is directly attributable to the acquisition of the items.

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. The carrying amount of the replaced part is derecognized. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.

Depreciation on property, plant and equipment is calculated using the straight-line method to allocate their cost to their residual values over their estimated useful lives, as follows:

Buildings	12-40 years
Plant and machinery	12-20 years
Vehicles and other equipment	4-20 years

The assets’ residual values and 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 (Note 2.11).

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized within “Other gains/(losses) – net” in the income statement.

Construction in progress

2.8 Construction in progress

Construction in progress represents buildings, various plant and equipment under construction and pending installation, and is stated at cost less government grants that compensate the Company for the cost of construction, and impairment losses. Cost comprises direct costs of construction as well as interest charges, and foreign exchange differences on related borrowed funds to the extent that they are regarded as an adjustment to interest charges, during the period of construction. Construction in progress is transferred to property, plant and equipment when the asset is substantially ready for its intended use. No depreciation is provided in respect of construction in progress.

Investment properties

2.9 Investment properties

Investment properties are properties which are owned or held under a leasehold interest either to earn rental income and/or for capital appreciation.

Investment properties are stated in the balance sheet at cost less accumulated depreciation and impairment losses (Note 2.11). Depreciation is provided over their estimated useful lives on a straight-line basis, after taking into account their estimated residual values. Estimated useful lives of the Group’s investment properties are 30-40 years.

Lease prepayments and other assets

2.10 Lease prepayments and other assets

Lease prepayments and other assets mainly represent prepayments for land use rights and catalysts used in production. These assets are carried at cost less accumulated amortisation and impairment losses. Lease prepayments and other assets are amortised on a straight-line basis over the respective periods of the rights and the estimated useful lives of the catalysts, as follows:

Land use rights	30-50 years
Patents	10-28 years
Catalyst	2-5 years

Impairment of non-financial assets

2.11 Impairment of non-financial assets

Intangible assets that have an indefinite useful life or intangible assets not ready to use are not subject to amortisation and are tested annually for impairment. Assets that are subject to amortisation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at each reporting date.

Financial assets

2.12 Financial assets

2.12.1 Classification

The Group classifies its financial assets in the following categories: at fair value through profit or loss, loans and receivables and available for sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition.

(a) Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets held for trading. A financial asset is classified in this category if acquired principally for the purpose of selling in the short term. Derivatives are also categorised as held for trading unless they are designated as hedges. Assets in this category are classified as current assets if expected to be settled within 12 months; otherwise, they are classified as non-current.

(b) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for the amounts that are settled or expected to be settled more than 12 months after the end of the reporting period. These are classified as non-current assets. The Group’s loans and receivables comprise “trade receivables, bills receivable and other receivables” and “cash and cash equivalents” in the balance sheet (Note 2.17 and 2.18).

(c) Available-for-sale financial assets

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless the investment matures or management intends to dispose of it within 12 months of the end of the reporting period.

2.12.2 Recognition and measurement

Regular way purchases and sales of financial assets are recognized on the trade-date – the date on which the Group commits to purchase or sell the asset. Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets and financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are subsequently carried at amortised cost using the effective interest method.

Gains or losses arising from changes in the fair value of the “financial liabilities at fair value through profit or loss” category are presented in the income statement within “Other gains/(losses) – net” in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognised in the income statement as part of “other income” when the Group’s right to receive payments is established.

Changes in the fair value of monetary and non-monetary securities classified as available for sale are recognised in “other comprehensive income”.

When securities classified as available for sale are sold or impaired, the accumulated fair value adjustments recognized in equity are included in the income statement as “gains and losses from investment securities”.

Interest on available-for-sale securities calculated using the effective interest method is recognized in the income statement as part of “other income”. Dividends on available-for-sale equity instruments are recognized in the income statement as part of other income when the Group’s right to receive payments is established.

Offsetting financial instruments

2.13 Offsetting financial instruments

Financial assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the asset and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the company or the counterparty.

Impairment of financial assets

2.14 Impairment of financial assets

(a) Assets carried at amortised cost

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or group of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a “loss event”) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated.

Evidence of impairment may include indications that the receivables or a group of receivables is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganisation, and where observable data indicate that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.

For loans and receivables category, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is reduced and the amount of the loss is recognized in the consolidated income statement. If a loan has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instrument’s fair value using an observable market price.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the consolidated income statement.

(b) Financial assets classified as available for sale

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired.

For debt securities, if any such evidence exists, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in profit or loss – is reclassified from equity and recognised in profit or loss. If, in a subsequent period, the fair value of a debt instrument classified as available for sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognised in profit or loss, the impairment loss is reversed through the consolidated income statement.

For equity investments, a significant or prolonged decline in the fair value of the security below its cost is also evidence that the assets are impaired. If any such evidence exists, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in profit or loss – is reclassified from equity and recognised in profit or loss. Impairment losses recognised in the consolidated income statement on equity instruments are not reversed through the consolidated income statement.

Derivative financial instruments

2.15 Derivative financial instruments

Derivative financial instruments of the Group are foreign exchange forward contracts, which are not designated as hedges.

Derivative financial instruments are initially recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value.

Fair values are obtained from quoted market prices in active markets, including recent market transactions, and through the use of valuation techniques, including discounted cash flow models and options pricing models, as appropriate. All derivatives are carried as assets when fair value is positive and as liabilities when fair value is negative.

The best evidence of the fair value of a derivative at initial recognition is the transaction price (i.e., the fair value of the consideration given or received) unless the fair value of that instrument is evidenced by comparison with other observable current market transactions in the same instrument or based on a valuation technique whose variables include only data from observable markets. When such evidence exists, the Group recognizes profits (losses) on that day.

Inventories

2.16 Inventories

Inventories are stated at the lower of cost and net realisable value. Cost is determined using the weighted average cost method. The cost of finished goods and work in progress comprises raw materials, direct labour, other direct costs and related production overheads (based on normal operating capacity). It excludes borrowing costs. Net realisable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses.

Trade receivables, bills receivable and other receivables

2.17 Trade receivables, bills receivable and other receivables

Trade receivables and bills receivable are amounts due from customers for merchandise sold or services performed in the ordinary course of business. If collection of trade receivables, bills receivable and other receivables is expected in one year or less (or in the normal operating cycle of the business if longer), they are classified as current assets. If not, they are presented as non-current assets.

Trade receivables, bills receivable and other receivables are recognized initially at fair value plus transaction costs and subsequently measured at amortised cost using the effective interest method, less allowance for impairment. See Note 2.12.2 for further information about the Group’s accounting for receivables and Note 2.14 for a description of the Group’s impairment policies.

Cash and cash equivalents

2.18 Cash and cash equivalents

In the consolidated statement of cash flows, cash and cash equivalents include cash in hand, deposits held at call with banks, other short-term highly liquid investments with original maturities of three months or less, and bank overdrafts. In the Group’s balance sheet, bank overdrafts are shown within borrowings in current liabilities.

Share capital

2.19 Share capital

Ordinary shares are classified as equity.

Incremental costs directly attributable to the issue of new shares are shown in equity as a deduction, net of tax, from the proceeds.

Safety production fund

2.20 Safety production fund

Under China’s law and regulation, the Group is required to accrue safety production fund at a certain percentage of the sales of dangerous goods. The fund is earmarked for improving the safety of production. The fund is accrued from retained earnings to other reserves and converted back to retained earnings when used.

Trade payables and other payables

2.21 Trade payables and other payables

Trade payables and other payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Trade payables and other payables are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Trade payables and other payables are recognized initially at fair value plus transaction costs and subsequently measured at amortised cost using the effective interest method.

Borrowings

2.22 Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortised cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method.

Fees paid on the establishment of loan facilities are recognized as transaction costs of the loan to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down occurs. To the extent there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalised as a pre-payment for liquidity services and amortised over the period of the facility to which it relates.

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the end of the reporting period.

Borrowing costs

2.23 Borrowing costs

General and specific 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.

Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalisation.

All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

Borrowing costs include interest expense, finance charges in respect of exchange differences arising from foreign currency borrowings to the extent that they are regarded as an adjustment to interest costs. The exchange gains and losses that are an adjustment to interest costs include the interest rate differential between borrowing costs that would be incurred if the entity had borrowed funds in its functional currency, and the borrowing costs actually incurred on foreign currency borrowings.

Current and deferred income tax

2.24 Current and deferred income tax

The tax expense for the period comprises current and deferred tax. Tax is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

(a) 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 countries where the Company’s subsidiaries, associates and joint ventures 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. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

(b) 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, the 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 utilised.

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 liability 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 recognised.

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 utilised.

(c) Offsetting

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.

Employee benefits

2.25 Employee benefits

(a) Pension obligations

The PRC employees of the Group are covered by various PRC government-sponsored defined-contribution pension plans under which the employees are entitled to a monthly pension based on certain formulas. The relevant government agencies are responsible for the pension liability to these employees when they retire. The Group contributes on a monthly basis to these pension plans for the employees which are determined at a certain percentage of their salaries. Under these plans, the Group has no obligation for post-retirement benefits beyond the contribution made. Contributions to these plans are expensed as incurred and contributions paid to the defined contribution pension plans for a staff are not available to reduce the Group’s future obligations to such defined-contribution pension plans even if the staff leaves the Group.

(b) Termination benefits

Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Group recognizes termination benefits at the earlier of the following dates: when Group demonstrably commits itself to terminate employment or to provide benefits as a result of voluntary redundancy by having a detailed formal plan which is without realistic possibility of withdrawal. Benefits falling due more than 12 months after the end of the reporting period are discounted to their present value.

Share-based payment

2.26 Share-based payment

(a) Equity-settled share-based payment transactions

The Group operates a number of equity-settled, share-based compensation plans, under which the entity receives services from employees as consideration for equity instruments (options) of the Group. The fair value of the employee services received in exchange for the grant of the options is recognised as an expense. The total amount to be expensed is determined by reference to the fair value of the options granted：

• including any market performance conditions such as an entity’s share price;

• excluding the impact of any service and non-market performance vesting conditions such as profitability, sales growth targets and remaining an employee of the entity over a specified time period; and

• including the impact of any non-vesting conditions such as the requirement for employees to save or holding shares for a specified period of time.

At the end of each reporting period, the Group revises its estimates of the number of options that are expected to vest based on the non-marketing performance and service conditions. It recognises the impact of the revision to original estimates, if any, in the income statement, with a corresponding adjustment to equity.

In addition, in some circumstances employees may provide services in advance of the grant date and therefore the grant date fair value is estimated for the purposes of recognising the expense during the period between service commencement period and grant date.

When the options are exercised, the Company issues new shares. The proceeds received net of any directly attributable transaction costs are credited to share capital.

(b) Share-based payment transactions among Group entities

The grant by the Company of options over its equity instruments to the employees of subsidiary undertakings in the Group is treated as a capital contribution. The fair value of employee services received, measured by reference to the grant date fair value, is recognised over the vesting period as an increase to investment in subsidiary undertakings, with a corresponding credit to equity in the parent entity accounts.

Provisions

2.27 Provisions

Provisions for environmental restoration, restructuring costs and legal claims are recognised 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. Restructuring provisions comprise lease termination penalties and employee termination payments. Provisions are not recognised for future operating losses.

Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognized even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognized as interest expense.

Revenue recognition

2.28 Revenue recognition

Revenue is measured at the fair value of the consideration received or receivable, and represents amounts receivable for goods supplied, stated net of discounts, returns and value added taxes. 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. The Group bases its estimates of return on historical results, taking into consideration the type of customers, the type of transactions and the specifics of each arrangement.

(a) Sales of petroleum and chemical products

Revenues associated with the sale of petroleum and chemical products are recognized in the income statement when the significant risks and rewards of ownership have been transferred to the buyer. Revenue excludes value added tax and is after deduction of any trade discounts and returns. No revenue is recognized if there are significant uncertainties regarding recovery of the consideration due to the possible return of goods, or when the amount of revenue and the costs incurred or to be incurred in respect of the transaction cannot be measured reliably.

(b) Pipeline transportation services

Revenues associated with pipeline transportation services are recognized by reference to the stage of completion (that is, when the services are rendered) of the transaction at the end of the reporting period and when the outcome of the transaction can be estimated reliably. The outcome of the transaction can be estimated reliably when the amount of revenue, the costs incurred and the stage of completion can be measured reliably and it is probable that the economic benefits associated with the transaction will flow to the Group.

(c) Rental income

Rental income from investment property is recognized in the income statement on a straight-line basis over the term of the lease.

Interest income

2.29 Interest income

Interest income is recognized using the effective interest method. When a loan and receivable is impaired, the Group reduces the carrying amount to its recoverable amount, being the estimated future cash flow discounted at the original effective interest rate of the instrument, and continues unwinding the discount as interest income. Interest income on impaired loans and receivables is recognized using the original effective interest rate.

Dividend income

2.30 Dividend income

Dividend income is recognized when the right to receive payment is established.

Government grants

2.31 Government grants

Grants from the government are recognised at their fair value where there is a reasonable assurance that the grant will be received and the Group will comply with all attached conditions.

Government grants relating to costs are deferred and recognised in the income statement over the period necessary to match them with the costs that they are intended to compensate.

Grants that compensate the Group for the cost of an asset are deducted from the carrying amount of the asset and consequently are effectively recognized in the income statement over the useful life of the asset by way of reduced depreciation expense.

Leases

2.32 Leases

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 (net of any incentives received from the lessor) are charged to the income statement on a straight-line basis over the period of the lease.

Dividend distribution

2.33 Dividend distribution

Dividend distribution to the Company’s shareholders is recognized as a liability in the Group’s financial statements in the period in which the dividends are approved by the Company’s shareholders.

Research and development costs

2.34 Research and development costs

Research and development costs comprise all costs that are directly attributable to research and development activities or that can be allocated on a reasonable basis to such activities. Research and development costs are recognized as intangible assets when the following criteria are met:

• it is technically feasible to complete the research and development project so that it will be available for use or sale;

• management intends to complete the research and development project, and use or sell it;

• it can be demonstrated how the research and development project will generate economic benefits;

• there are adequate technical, financial and other resources to complete the development and the ability to use or sell the research and development project; and

• the expenditure attributable to the research and development project during its development phase can be reliably measured.

Other research and development expenditure that do not meet these criteria are recognized as an expense as incurred. Research and development costs previously recognized as an expense are not recognized as an asset in a subsequent period.
