Mimecast Limited (Mimecast Jersey) is a public limited company organized under the laws of the Bailiwick of Jersey on July 28, 2015. On November 4, 2015, Mimecast Jersey changed its corporate structure whereby it became the holding company of Mimecast Limited (Mimecast UK), a private limited company incorporated in 2003 under the laws of England and Wales, and its wholly-owned subsidiaries by way of a share-for-share exchange in which the shareholders of Mimecast UK exchanged their shares in Mimecast UK for an identical number of shares of the same class in Mimecast Jersey. Upon the exchange, the historical consolidated financial statements of Mimecast UK became the historical consolidated financial statements of Mimecast Jersey.

Mimecast Jersey and its subsidiaries (together the Group, the Company, Mimecast or we) is headquartered in London, England. The principal activity of the Group is the provision of email management services. Mimecast delivers a software-as-a-service (SaaS) enterprise email management service for archiving, continuity, and security, web security and awareness training. By unifying disparate and fragmented email environments into one holistic solution from the cloud, Mimecast minimizes risk and reduces cost and complexity while providing total end-to-end control of email. Mimecast’s proprietary software platform provides a single system to address key email management issues. Mimecast operates principally in Europe, North America, Africa, and Australia.

The Company is subject to a number of risks and uncertainties common to companies in similar industries and stages of development including, but not limited to, rapid technological changes, competition from substitute products and services from larger companies, customer concentration, management of international activities, protection of proprietary rights, patent litigation, and dependence on key individuals.

The accompanying interim condensed consolidated financial statements are unaudited. These financial statements and notes should be read in conjunction with the audited consolidated financial statements for the year ended March 31, 2018 and related notes, together with management’s discussion and analysis of financial condition and results of operations, contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on May 29, 2018.

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (GAAP) have been condensed or omitted. In the opinion of management, the unaudited condensed consolidated financial statements and notes have been prepared on the same basis as the audited consolidated financial statements for the year ended March 31, 2018 contained in the Company’s Annual Report on Form 10-K and include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position as of September 30, 2018, and for the three and six months ended September 30, 2018 and 2017. These interim periods are not necessarily indicative of the results to be expected for any other interim period or the full year.

The Company reclassified $0.1 million of provision for doubtful accounts to accounts receivable within its condensed consolidated statements of cash flows for the six months ended September 30, 2017 in this quarterly report on Form 10-Q to conform to current period presentation. This had no impact on the Company’s previously reported results of operations or its balance sheets.

The accompanying condensed consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the condensed consolidated financial statements. As of September 30, 2018, the Company’s significant accounting policies and estimates, which are detailed in the Company’s Annual Report on Form 10-K, have not changed, except as discussed below.

Effective April 1, 2018, the Company adopted the requirements of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09 or ASC 606) under the modified retrospective method of transition, which was applied to all customer contracts that were not completed on the effective date of ASC 606. The Company implemented internal controls and key system functionality to enable the preparation of financial information on adoption. The adoption of ASC 606 resulted in changes to the Company’s accounting policies for revenue recognition previously recognized under ASC 605, Revenue Recognition (Legacy GAAP), as detailed below.

Under ASC 606 the Company recognizes revenue upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. To achieve the core principle of ASC 606, the Company performs the following steps:

The Company derives its revenue from two sources: (1) subscription revenues, which are comprised of subscription fees from customers accessing the Company’s cloud services and from customers purchasing additional support beyond the standard support that is included in the basic subscription fees; and (2) related professional services and other revenue, which consists primarily of certain performance obligations related to set-up, ingestion, consulting and training fees.

In the three and six months ended September 30, 2018 and 2017, subscription revenue made up the substantial majority of the Company’s revenue and professional services and other revenue made up less than 5% of the Company’s revenue.

The Company’s subscription arrangements provide customers the right to access the Company’s hosted software applications. Customers do not have the right to take possession of the Company’s software during the hosting arrangement.

The Company sells its products and services directly through the Company’s sales force and also indirectly through third-party resellers. In accordance with the provisions of ASC 606, the Company has considered certain factors in determining whether the end-user or the third-party reseller is the customer in arrangements involving resellers. The Company concluded that in the majority of transactions with resellers, the reseller is the customer. In these arrangements, the Company considered that it is the reseller, and not the Company, that has the relationship with the end-user. Specifically, the reseller has the ability to set pricing with the end-user and the credit risk with the end-user is borne by the reseller. Further, the reseller is not obligated to report its transaction price with the end-user to the Company, and in the majority of transactions, the Company is unable to determine the amount paid by the end-user customer to the reseller in these transactions. As a result of such considerations, revenue for these transactions is presented in the accompanying condensed consolidated statements of operations based upon the amount billed to the reseller. For transactions where we have determined that the end-user is the ultimate customer, revenue is presented in the accompanying condensed consolidated statements of operations based on the transaction price with the end-user.

The Company recognizes subscription and support revenue ratably over the term of the contract, typically one year in duration, beginning on the date the customer is provided access to the Company’s service. For performance obligations related to set-up and ingestion, including implementation assistance and data migration services, respectively, the Company recognizes revenue using output measures of performance that reflect the transfer of promised services to the customer consistent with progress to completion. The Company recognizes revenue on training, consulting, and other professional services contracts using output measures of performance as services are completed. Training, consulting, and other professional services are considered separate performance obligations.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. The Company primarily bills and collects payments from customers for its services in advance on a monthly and annual basis.

In some instances, the Company receives non-refundable upfront payments for activities that do not constitute a promise to transfer a service and therefore are considered administrative tasks, not separate performance obligations. The upfront payments are evaluated to determine whether a material right to a discount upon renewal of the subscription exists. When the Company concludes a material right does not exist, the Company recognizes revenue related to the upfront payment over the initial contract term. When the Company concludes a material right does exist, the Company recognizes revenue related to the upfront payment, under the look-through method, over the estimated customer benefit period, which has been determined to be six years.

All of the Company’s performance obligations, and associated revenue, are generally transferred to customers over time, with the exception of training, consulting and other professional services, which are generally transferred to the customer at a point in time.

Some of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. The Company determines the standalone selling prices based on the Company’s overall pricing objectives, taking into consideration market conditions and other factors, including the value of the Company’s contracts, the products sold, customer demographics, the Company’s sales channel, and the number and size of users within the Company’s contracts.

Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from subscription and other services described above and is recognized as the revenue recognition criteria are met. Deferred revenue that is expected to be recognized during the succeeding twelve-month period is recorded as current deferred revenue and the remaining portion is recorded as non-current in the accompanying condensed consolidated balance sheets.

As part of the Company’s adoption of ASC 606, the Company capitalizes incremental costs of obtaining revenue contracts, which primarily consist of commissions paid to its sales representatives. The Company amortizes these commissions over six years on a systematic basis, consistent with the pattern of transfer of the goods or services to which the asset relates. Six years represents the estimated benefit period of the customer relationship taking into account factors such as peer estimates of technology lives and customer lives as well as the Company's own historical data. No commissions are paid related to contract renewals. The current and noncurrent portions of deferred commissions are included in deferred contract costs, net, and deferred contract costs, net of current portion, respectively, in the accompanying condensed consolidated balance sheets. Amortization of capitalized costs to obtain revenue contracts is included in sales and marketing expense in the accompanying condensed consolidated statements of operations.

The adoption of ASC 606 resulted in a decrease to deferred revenue of $6.0 million and an increase of $23.8 million in deferred contract costs as of April 1, 2018. The Company recorded the deferred tax impact associated with the cumulative-effect adjustment of adopting ASC 606 to accumulated deficit with an equal and offsetting adjustment to the Company’s valuation allowance. The decrease to deferred revenue upon adoption was primarily due to a change in the accounting treatment for certain upfront fees that were accounted for as a single unit of account under Legacy GAAP and are accounted for as separate performance obligations under ASC 606. The increase in deferred contract costs was the result of the capitalization of certain commissions that were determined to be incremental costs of obtaining a contract. Under Legacy GAAP, the Company expensed all commission costs as incurred.

As a result of the adoption of ASC 606, the Company’s accumulated deficit decreased by $29.9 million as of April 1, 2018, which was the net cumulative impact associated with the capitalization of sales commissions and the adjustment to deferred revenue.

The cumulative effect of the changes made to the Company’s April 1, 2018 balance sheet for the adoption of ASC 606 were as follows:

	Balance as of March 31, 2018			Adjustments Due to Adoption of ASC 606			Balance as of April 1, 2018
Assets
Deferred contract costs, net	$	—		$	5,494		$	5,494
Deferred contract costs, net of current portion		—			18,339			18,339
Liabilities
Deferred revenue		123,057			(517	)		122,540

Shareholders' equity
Accumulated deficit		(106,507	)		29,876			(76,631	)

In accordance with the requirements of ASC 606, the disclosure for the quantitative effect and the significant changes between the reported results under ASC 606 and those that would have been reported under Legacy GAAP on our unaudited condensed consolidated income statement and balance sheet was as follows:

	As of September 30, 2018

Accumulated deficit		(82,160	)		(117,943	)		35,783

Revenue recognized during the three and six months ended September 30, 2018 from amounts included in deferred revenue at the beginning of the period was approximately $53.4 million and $84.5 million, respectively. Revenue recognized during the three and six months ended September 30, 2018 from performance obligations satisfied or partially satisfied in previous periods was not material.

Contracted revenue as of September 30, 2018 that has not yet been recognized (“contracted not recognized”) was $74.0 million, which includes deferred revenue and non-cancellable amounts that will be invoiced and recognized as revenue in future periods and excludes contracts with an original expected length of one year or less. The Company expects 51% of contracted and not recognized revenue to be recognized over the next twelve months, 45% in years two and three, with the remaining balance recognized thereafter.

The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period.

Significant estimates relied upon in preparing these condensed consolidated financial statements include revenue recognition, variable consideration, valuation at fair value of assets acquired or sold, including intangibles, goodwill, tangible assets, and liabilities assumed, amortization periods, expected future cash flows used to evaluate the recoverability of long-lived assets, contingent liabilities, construction financing lease obligations, restructuring liabilities, expensing and capitalization of research and development costs for internal-use software, the determination of the fair value of share-based awards issued, the average period of benefit associated with costs capitalized to obtain revenue contracts and the recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. Changes in estimates are recorded in the period in which they become known.

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. The Company has evaluated all subsequent events and determined that there are no material recognized or unrecognized subsequent events requiring disclosure.

The Company has no off-balance sheet risk, such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of cash and cash equivalents, investments and accounts receivable. The Company maintains its cash, cash equivalents and investments with major financial institutions of high-credit quality. Although the Company deposits its cash with multiple financial institutions, its deposits, at times, may exceed federally insured limits.

Credit risk with respect to accounts receivable is dispersed due to our large number of customers. The Company’s accounts receivable are derived from revenue earned from customers primarily located in the United States, the United Kingdom and South Africa. The Company generally does not require its customers to provide collateral or other security to support accounts receivable. Credit losses historically have not been significant and the Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable. As of September 30, 2018 and March 31, 2018, no individual customer represented more than 10% of the Company’s accounts receivable. During the three and six months ended September 30, 2018 and 2017, no individual customer represented more than 10% of the Company’s revenue.

As of September 30, 2018, the Company’s investments consisted primarily of investment-grade fixed income corporate debt securities with maturities ranging from less than one month to five months and non-U.S. government securities with maturities in approximately one month. We diversify our investment portfolio by investing in multiple types of investment-grade securities and attempt to mitigate a risk of loss by using a third-party investment manager.

The Company considers all highly liquid instruments purchased with an original maturity date of 90 days or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks, amounts held in interest-bearing money market funds and investments with maturities of 90 days or less from the date of purchase. Cash equivalents are carried at cost, which approximates their fair market value. Investments not classified as cash equivalents are presented as either short-term or long-term investments based on both their stated maturities as well as the time period the Company intends to hold such securities. The Company determines the appropriate classification of investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company adjusts the cost of investments for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion in interest income.

The Company has classified all of its investments as of September 30, 2018, as available-for-sale pursuant to Accounting Standard Codification (ASC) 320, Investments – Debt and Equity Securities. The Company records available-for-sale securities at fair value, with unrealized gains and losses included in accumulated other comprehensive loss in shareholders’ equity. The Company includes interest and dividends on securities classified as available-for-sale in interest income. Realized gains and losses are recorded in the condensed consolidated statements of operations and comprehensive loss based on the specific-identification method. There were no realized gains or losses on investments for the three and six months ended September 30, 2018 and 2017.

The Company reviews investments for other-than-temporary impairment whenever the fair value of an investment is less than its amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. Other-than-temporary impairments of investments are recognized in the condensed consolidated statements of operations if the Company has experienced a credit loss, has the intent to sell the investment, or if it is more likely than not that the Company will be required to sell the investment before recovery of the amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, compliance with the Company’s investment policy, the severity and the duration of the impairment and changes in value subsequent to the end of the period. As of September 30, 2018, the aggregate fair value of investments held by the Company in an unrealized loss position for less than twelve months was $13.5 million. As of September 30, 2018, the Company determined that no other-than-temporary impairments were required to be recognized in the condensed consolidated statements of operations.

The following is a summary of cash, cash equivalents and investments as of September 30, 2018 and March 31, 2018:

The Company’s financial instruments include cash, cash equivalents, accounts receivable, investments, accounts payable, accrued expenses and borrowings under the Company’s long-term debt arrangements. The carrying amount of the Company’s long-term debt arrangements approximates its fair values due to the interest rates the Company believes it could obtain for borrowings with similar terms. The Company’s investments are classified as available-for-sale and reported at fair value in accordance with the market approach utilizing quoted prices that were directly or indirectly observable. The carrying amount of the remainder of the Company’s financial instruments approximated their fair values as of September 30, 2018 and March 31, 2018, due to the short-term nature of those instruments.

The Company has evaluated the estimated fair value of financial instruments using available market information. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts.

Fair values determined using “Level 1 inputs” utilize unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access. Fair values determined using “Level 2 Inputs” utilize quoted prices that are directly or indirectly observable. Fair values determined using “Level 3 inputs” utilize unobservable inputs for determining fair values of assets or liabilities that reflect an entity's own assumptions in pricing assets or liabilities. As of September 30, 2018 and March 31, 2018, the Company did not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3).

The Company measures eligible assets and liabilities at fair value, with changes in value recognized in earnings. Fair value treatment may be elected either upon initial recognition of an eligible asset or liability or, for an existing asset or liability, if an event triggers a new basis of accounting. The Company did not elect to remeasure any of its existing financial assets or liabilities, and did not elect the fair value option for any financial assets and liabilities transacted in the three and six months ended September 30, 2018 and 2017.

The following table summarizes financial assets measured and recorded at fair value on a recurring basis in the accompanying condensed consolidated balance sheets as of September 30, 2018 and March 31, 2018, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

Costs incurred to develop software applications used in the Company’s SaaS platform consist of certain direct costs of materials and services incurred in developing or obtaining internal-use computer software, and payroll and payroll-related costs for employees who are directly associated with, and who devote time to, the project. These costs generally consist of internal labor during configuration, coding, and testing activities. Research and development costs incurred during the preliminary project stage or costs incurred for data conversion activities, training, maintenance and general and administrative or overhead costs are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized until the application is substantially complete and ready for its intended use. Qualified costs incurred during the operating stage of the Company’s software applications relating to upgrades and enhancements are capitalized to the extent it is probable that they will result in added functionality, while costs incurred for maintenance of, and minor upgrades and enhancements to, internal-use software are expensed as incurred. During the three and six months ended September 30, 2018 and 2017, the Company believes the substantial majority of its development efforts were either in the preliminary project stage of development or in the operation stage (post-implementation), and accordingly, no costs have been capitalized during these periods. These costs are included in the accompanying condensed consolidated statements of operations as research and development expense.

The Company evaluates its accounting for fees paid in cloud computing arrangements (CCA) including determining whether the CCA includes a license to internal-use software. If the CCA includes a software license, the Company accounts for the software license as an intangible asset. Acquired software licenses are recognized and measured at cost, which includes the present value of the license obligation if the license is to be paid for over time. If the CCA does not include a software license, the Company accounts for the arrangement as a service contract (hosting arrangement) and hosting costs are generally expensed as incurred.

Upon adoption of ASU 2018-15, the Company evaluates upfront costs including implementation, set-up or other costs (collectively, implementation costs) for hosting arrangements under the internal-use software framework. Costs related to preliminary project activities and post implementation activities are expensed as incurred, whereas costs incurred in the development stage are generally capitalized. Capitalized implementation costs are amortized on a straight-line basis over the expected term of the hosting arrangement, which includes consideration of the noncancellable contractual term and reasonably certain renewals. During the three and six months ended September 30, 2018, the Company capitalized $0.9 million of implementation costs related to hosting arrangements that were incurred during the application development stage. These capitalized implementation costs will be amortized over the expected term of the arrangement determined to be four years through sales and marketing expense within the condensed consolidated statements of operations.

The Company calculates basic and diluted net loss per ordinary share by dividing net loss by the weighted-average number of ordinary shares outstanding during the period. The Company has excluded other potentially dilutive shares, which include outstanding options to purchase ordinary shares and unvested restricted share units, from the weighted-average number of ordinary shares outstanding as their inclusion in the computation for all periods would be anti-dilutive due to net losses incurred.

The following potentially dilutive ordinary share equivalents have been excluded from the calculation of diluted weighted-average shares outstanding as their effect would have been anti-dilutive for the periods presented (in thousands):

As of September 30, 2018, the Company has four share-based compensation plans and an employee share purchase plan. Prior to the Company’s initial public offering (IPO) in November 2015, the Company granted share-based awards under three share option plans, which were the Mimecast Limited 2007 Key Employee Share Option Plan (the 2007 Plan), the Mimecast Limited 2010 EMI Share Option Scheme (the 2010 Plan), and the Mimecast Limited Approved Share Option Plan (the Approved Plan) (the 2007 Plan, the 2010 Plan and the Approved Plan, collectively, the Historical Plans). Upon the closing of the IPO, the Mimecast Limited 2015 Share Option and Incentive Plan (the 2015 Plan) and the 2015 Employee Share Purchase Plan (the ESPP) became effective.

The fair value of each share option issued under the 2015 Plan was estimated using the Black-Scholes option-pricing model that used the following weighted-average assumptions:

The weighted-average per share fair value of options granted to employees during the six months ended September 30, 2018 and 2017 was $16.28 and $10.58, respectively. As of September 30, 2018, the number of options and awards available for future grant under the 2015 Plan was 6,387,854.

Share option activity under the 2015 Plan and the Historical Plans for the six months ended September 30, 2018 was as follows:

	Number of Awards			Weighted Average Exercise Price (2)		Weighted Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands) (1)
Outstanding as of March 31, 2018		6,229,860		$	13.78		7.40	$	134,859
Options granted		2,142,948		$	36.75
Options exercised		(1,011,211	)	$	7.69
Options forfeited and cancelled		(197,757	)	$	21.49
Outstanding as of September 30, 2018		7,163,840		$	21.29		7.89	$	147,726
Exercisable as of September 30, 2018		2,176,150		$	10.30		6.05	$	68,721

The total intrinsic value of options exercised was $34.8 million for the six months ended September 30, 2018. Total cash proceeds from option exercises was $7.8 million for the six months ended September 30, 2018.

As of September 30, 2018, there was approximately $51.8 million of unrecognized share-based compensation related to unvested share options, which is expected to be recognized over a weighted-average period of 3.05 years.

Initially, a total of 1.1 million shares of the Company's ordinary shares were reserved for future issuance under the ESPP. This number is subject to change in the event of a share split, share dividend or other change in capitalization. The ESPP may be terminated or amended by the board of directors at any time.

The ESPP permits eligible employees to purchase shares by authorizing payroll deductions from 1% to 10% of his or her eligible compensation during each six month offering period, which starts on the first business day in January and July each year. Unless an employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to purchase shares on the last day of the offering period at a price equal to 85% of the fair market value of the shares on the first business day or last business day of the offering period, whichever is lower. In the three and six months ended September 30, 2018, the Company recognized $0.3 million and $0.5 million of share-based compensation expense under the ESPP.

As of September 30, 2018, there were 1.0 million shares of the Company's ordinary shares available for future issuance under the ESPP.

The Company grants RSUs to its Non-Employee Directors and its employees. Non-Employee Directors receive an initial RSU grant upon joining the BOD that vests over three years and an annual grant each year thereafter that vests fully on the one-year anniversary of the grant date. RSUs granted to Company employees vest in four equal annual installments.

RSU activity under the 2015 Plan for the six months ended September 30, 2018 was as follows:

As of September 30, 2018, there was approximately $13.8 million of unrecognized share-based compensation expense related to unvested RSUs, which is expected to be recognized over a weighted-average period of 3.38 years.

Share-based compensation expense recognized under the 2015 Plan, Historical Plans and ESPP in the accompanying condensed consolidated statements of operations was as follows:

	Three months ended September 30,				Six months ended September 30,
	2018		2017		2018		2017
Cost of revenue	$	420	$	236	$	824	$	442
Research and development		1,571		601		2,901		1,283
Sales and marketing		1,965		1,122		3,796		2,070
General and administrative		2,153		951		3,769		1,761
Total share-based compensation expense	$	6,109	$	2,910	$	11,290	$	5,556

In certain situations, the board of directors has approved modifications to employee share option agreements, including acceleration of vesting or the removal of exercise restrictions for share options for which the service-based vesting has been satisfied which resulted in additional share-based compensation expense. The total modification expense included in the table above for the three months ended September 30, 2018 and 2017 was $0.4 million and $0.1 million, respectively. The total modification expense included in the table above for the six months ended September 30, 2018 and 2017 was $0.6 million and $0.4 million, respectively. As of September 30, 2018, the Company had unrecognized compensation of $2.5 million related to modified share-based awards that will be recognized over a remaining requisite service period of 0.5 years.

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions, other events, and circumstances from non-owner sources. Comprehensive loss consists of net loss and other comprehensive income (loss), which includes certain changes in equity that are excluded from net loss. Specifically, cumulative foreign currency translation adjustments and unrealized gains and losses on investments are included in accumulated other comprehensive loss. As of September 30, 2018 and March 31, 2018, accumulated other comprehensive loss is presented separately on the condensed consolidated balance sheets and consists of cumulative foreign currency translation adjustments and unrealized gains and losses on investments.

On July 31, 2018, the Company entered into a share purchase agreement (the Purchase Agreement) pursuant to which it acquired Solebit LABS Ltd. (Solebit), a company organized under the laws of the State of Israel, that provides security software. Solebit’s technology enhances security for the Company’s customers and adds to its ability to detect and prevent cyber-attacks, zero day threats and malware across email and the web in real time. This acquisition further enhances the Company’s cyber resilience platform architecture.

Prior to the closing of the acquisition, the Company held an ownership interest in Solebit of approximately 1.5%. Upon completion of the acquisition, the Company recognized a gain of $0.3 million recorded in foreign exchange expense and other, net within the condensed consolidated statement of operations for the remeasurement of its previously held ownership interest to fair value, which was $0.8 million.

The total preliminary purchase price of $96.5 million included cash payments of approximately $96.1 million, inclusive of $8.8 million in purchase price held in escrow. The escrow is being held in respect of claims for indemnification for one year from the purchase date. The preliminary amounts due from sellers of $0.5 million includes working capital adjustments and certain preliminary one-year indemnification period purchase price adjustments identified by the Company. The preliminary purchase price, cash payments and purchase price allocation are subject to finalization of amounts due from the seller for the one-year indemnification period adjustments and potential working capital adjustments. The Company expects to finalize the purchase price within the required one-year measurement period.

The acquisition of Solebit has been accounted for as a business combination and, in accordance with ASC 805, Business Combinations, the Company has recorded the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. The following table summarizes the preliminary purchase price allocation recorded in the quarter ended September 30, 2018 (in thousands):

Preliminary purchase consideration:
Total cash paid, net of acquired cash	$	85,733
Cash and cash equivalents acquired		10,410
Preliminary amounts due from sellers		(492	)
Fair value of previously held asset		828
Total preliminary purchase price consideration	$	96,479

Fair value of assets acquired and liabilities assumed:
Cash and cash equivalents	$	10,410
Prepaid expenses and other current assets		75
Intangible assets		16,964
Goodwill		74,395
Total assets acquired		101,844
Accounts payable		(18	)
Accrued expenses and other current liabilities		(2,335	)
Deferred revenue		(663	)
Other non-current liabilities		(2,349	)
Total fair value of assets acquired and liabilities assumed	$	96,479

In the three and six months ended September 30, 2018, acquisition-related expenses were $0.6 million and $1.0 million, respectively. Acquisition-related expenses have been included primarily in general and administrative expenses in the condensed consolidated statements of operations. The operating results of Solebit are included in the condensed consolidated statements of operations beginning on the acquisition date.

The significant intangible assets identified in the preliminary purchase price allocation discussed above include developed technology and customer relationships, which are amortized over their respective useful lives on a straight-line basis when the pattern in which their economic benefits will be consumed cannot be reliably determined. To value the developed technology asset, the Company utilized the income approach, specifically a discounted cash-flow method known as the multi-period excess earnings method. Customer relationships represent the underlying relationships with certain customers to provide ongoing services for products sold. The Company utilized the income approach, specifically the distribution method, a subset of the excess-earnings method to value the customer relationships.

A portion of the purchase price has been allocated to intangible assets and goodwill, respectively, and is reflected in the tables above. The fair value of the assets acquired and liabilities assumed is less than the purchase price, resulting in the recognition of goodwill. The goodwill reflects the value of the synergies we expect to realize and the assembled workforce and is not deductible for tax purposes. The purchase price has been allocated to the tangible and intangible assets acquired and liabilities assumed based upon the respective estimates of fair value as of the date of the acquisition, which remains preliminary, and using assumptions that the Company’s management believes are reasonable given the information then available. The final allocation of the purchase price may differ materially from the information presented in these condensed consolidated financial statements. Any changes to the preliminary estimates of the fair value of the assets acquired and liabilities assumed during the measurement period will be recorded as adjustments to those assets and liabilities and residual amounts will be allocated to goodwill.

The following table presents the estimated fair values and useful lives of the identifiable intangible assets acquired:

The following unaudited pro forma information presents the condensed combined results of operations of the Company and Solebit for the three and six months ended September 30, 2018 and 2017, as if the acquisition of Solebit had been completed on April 1, 2017. These pro forma condensed consolidated financial results have been prepared for comparative purposes only and include certain adjustments that reflect pro forma results of operations such as fair value adjustments (step-downs) for deferred revenue, increased amortization for the fair value of acquired intangible assets and adjustments to eliminate transaction costs incurred by the Company and Solebit.

The unaudited pro forma results do not reflect any operating efficiencies or potential cost savings which may result from the consolidation of the operations of the Company and Solebit. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of the results of operations that actually would have been achieved had the acquisition occurred as of April 1, 2017, nor are they intended to represent or be indicative of future results of operations (in thousands, except per share amounts):

On July 9, 2018, the Company acquired ATAATA, Inc. (Ataata), a privately-owned company based in the United States, for cash consideration of approximately $25.1 million, net of cash acquired of $1.9 million. Ataata is a cyber security training and awareness platform designed to reduce human error in the workplace and help enable organizations to become more secure by changing the security culture of their employees. The acquisition will allow customers to measure cyber risk training effectiveness by converting behavior observations into actionable risk metrics for security professionals. The addition of security awareness training and risk scoring and analysis strengthens the Company’s cyber resilience for email capabilities.

The acquisition of Ataata has been accounted for as a business combination and, in accordance with ASC 805, Business Combinations, the Company has recorded the assets acquired and liabilities assumed at their respective fair values as of the acquisition date.

The preliminary purchase price allocation primarily consisted of $1.5 million of identifiable intangible assets and approximately $22.6 million of goodwill that is not deductible for tax purposes. The identifiable intangible assets primarily include developed technology of $1.4 million and customer relationships of $0.1 million, with estimated useful lives of ten and six years, respectively. The goodwill balance is primarily attributed to the expanded market opportunities when combining Ataata's awareness training technology with the Company’s other offerings. The preliminary purchase price and allocations are subject to finalization of amounts due from the seller inclusive of certain working capital and one-year indemnification period adjustments.

In the three and six months ended September 30, 2018, acquisition-related expenses were $0.1 million and $0.5 million, respectively. Acquisition-related expenses have been included primarily in general and administrative expenses in the condensed consolidated statements of operations. The operating results of Ataata are included in the condensed consolidated statements of operations beginning on the acquisition date.

The Company has not presented pro forma results of operations for the Ataata acquisition because it is not material to the Company's condensed consolidated results of operations, financial position, or cash flows.

The Company recorded amortization expense of $1.2 million and $2.0 million for the three and six months ended September 30, 2018. Amortization relating to developed technology and capitalized software was recorded within cost of revenue and amortization of customer relationships and trade names was recorded within sales and marketing expenses.

Future estimated amortization expense of intangible assets as of September 30, 2018, is as follows:

On July 23, 2018, the Company entered into a credit agreement (the Credit Agreement) with certain lenders, and JPMorgan Chase Bank, N.A., as administrative agent (the Administrative Agent), which provided the Company with a $100.0 million senior secured term loan and a $50.0 million senior secured revolving credit facility (collectively, the Credit Facility). The proceeds of the

Credit Facility, net of $2.3 million of debt issuance costs, are available to fund working capital and for other corporate purposes, including to finance permitted acquisitions and investments. Interest under the Credit Facility accrues at a rate between LIBOR plus 1.375% and LIBOR plus 1.875%, based on the Company’s ratio of indebtedness to earnings before interest, taxes, depreciation, amortization and certain other adjustments (Consolidated EBITDA). Based on this ratio, the current interest rate as of September 30, 2018 under the Credit Facility is LIBOR plus 1.625%. The term of the Credit Facility is five years, maturing on July 23, 2023. At the time the Company entered into the Credit Agreement, there was no outstanding debt.

The Credit Agreement has financial covenants that require the Company to maintain a Consolidated Secured Leverage Ratio (as defined in the Credit Agreement), commencing on September 30, 2018, of not more than 3.00 to 1.00 for the four consecutive fiscal quarter period ending on the last day of each fiscal quarter (the Reference Period), with a step-up to 3.50 to 1.00 for any four-quarter period in which the Company consummates a permitted acquisition having an aggregate purchase price in excess of $25,000,000. The Company must also maintain a Consolidated Interest Expense Ratio (as defined in the Credit Agreement) of 3.00 to 1.00 commencing on September 30, 2018 and for each Reference Period thereafter. The Company was in compliance with all covenants as of September 30, 2018.

The Company allocated debt issuance costs on a pro-rata basis between the senior secured term loan and senior secured revolving credit facility. The debt issuance costs on the senior secured term loan are recorded as a reduction of debt and are amortized and recognized as additional interest expense over the life of the debt instrument using the effective interest method. The debt issuance costs on the senior secured revolving credit facility are recorded in other assets and are amortized and recognized as additional interest expense over the life of the senior secured revolving credit facility on a straight-line basis. As of September 30, 2018, the balance of debt issuance costs recorded as a reduction of debt was $1.4 million and the balance of debt issuance costs recorded in other assets was $0.7 million.

All obligations under the Credit Agreement are unconditionally guaranteed by all of the Company’s material direct and indirect subsidiaries organized under the laws of the United States, the United Kingdom, the Bailiwick of Jersey, and other jurisdictions agreed to by the Company and the Administrative Agent, with certain exceptions. These guarantees are secured by substantially all of the present and future property and assets of the guarantors, with certain exclusions.

As of September 30, 2018, the Company had $99.4 million outstanding on the senior secured term loan and had no outstanding borrowings under the senior secured revolving credit facility. Total availability under the senior secured revolving credit facility is reduced by outstanding letters of credit of $3.9 million. As of September 30, 2018, total availability under the senior secured revolving credit facility was $46.1 million. Future minimum principal payment obligations under the senior secured term loan are as follows:

The Company has entered into various capital lease arrangements for computer equipment with non-cancelable terms through January 2022. As of September 30, 2018, future minimum commitments for capital leases were as follows:

The Company leases certain facilities under build-to-suit leases whereby the Company is deemed to be the owner of the building during the construction period for accounting purposes. For build-to-suit leases, the Company recorded certain estimated construction costs incurred and reported to it by the landlord for the buildings as an asset and corresponding construction financing lease obligation on the condensed consolidated balance sheets. Since the Company’s unit of account is related only to its portion of the buildings, the Company determined that it does not have land leases and has not recorded rent expense attributable to the land. Any incremental costs incurred directly by the Company are also capitalized. In each reporting period, the landlord estimates and reports to the Company construction costs incurred to date for the buildings and the Company records its portion using allocation estimates. The Company periodically meets with the landlord and its construction manager to review these estimates and observe construction progress before recording such amounts.

The construction of the Company’s Lexington, MA – U.S. headquarters was substantially completed during the quarter ended March 31, 2018, and because the Company concluded it had a collateralized letter of credit of $1.3 million, the Company did not meet the sale-leaseback criteria for derecognition of the building asset and liability. As a result, the Company continues to be the deemed owner of the building and will treat the lease as a financing obligation and depreciate the asset in accordance with the Company’s accounting policy.

The monthly rent payments made to the lessor under the lease agreement are recorded in the Company’s financial statements as principal and interest on the financing obligation. For the three and six months ended September 30, 2018, interest expense on lease financing obligations was $0.5 million and $0.9 million, respectively. As of September 30, 2018, the future estimated commitments related to the financing obligations were $38.5 million and $10.2 million for principal and interest, respectively, through January 31, 2028.

In January 2018, the Company entered into an Agreement for Lease (AFL) for its new U.K. headquarters located in London, England (UK Building). The AFL was entered into around the time the landlord had commenced a construction project to refurbish the UK Building and includes terms and conditions that are in effect during the construction project. Additionally, the AFL includes Leases in Agreed Form (Leases) to be executed upon completion of the construction project, which is expected in or around February 2019. Under the terms of the AFL and Leases, the Company will initially lease approximately 113,000 square feet of space for 56.50 British pounds per square foot per year over an initial noncancelable term of 10 years after initial occupancy, which is expected in the Company’s third fiscal quarter of 2020. The Company determined that it will account for the AFL as a build-to-suit lease as of March 31, 2018.

As of September 30, 2018, Property and equipment, net, includes $40.6 million related to the UK Building and construction costs for the UK Building. The construction financing lease obligation related to the UK Building was $39.7 million and was incurred by the landlord only and no cash was paid to the landlord by us related to the UK Building since lease inception.

Once the landlord completes the construction of the UK Building, the Company will evaluate the AFL and Leases in order to determine whether or not the AFL and Leases meet the criteria for “sale-leaseback” treatment. If the AFL and Leases meet the “sale-leaseback” criteria, the Company will remove the asset and the related liability from its condensed consolidated balance sheet and treat the Leases as either an operating or a capital lease based on the Company’s assessment of the accounting guidance. If the Company continues to be the deemed owner, the Company will treat the AFL and Leases as a financing obligation and will depreciate the asset in accordance with the Company’s accounting policy.

The Company, from time to time, may be party to litigation arising in the ordinary course of its business. The Company was not subject to any material legal proceedings during the three and six months ended September 30, 2018 and 2017, and, to the best of its knowledge, no material legal proceedings are currently pending or threatened.

The Company typically enters into indemnification agreements with customers in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses suffered or incurred as a result of claims of intellectual property infringement. These indemnification agreements are provisions of the applicable customer agreement. Based on when clients first sign an agreement for the Company’s service, the maximum potential amount of future payments the Company could be required to make under certain of these indemnification agreements is unlimited. Based on historical experience and information known as of September 30, 2018 and March 31, 2018, the Company has not incurred any costs for the above guarantees and indemnities.

In certain circumstances, the Company warrants that its services will perform in all material respects in accordance with its standard published specification documentation in effect at the time of delivery of the services to the customer for the term of the agreement. To date, the Company has not incurred significant expense under its warranties and, as a result, the Company believes the estimated fair value of these agreements is immaterial.

The Company allocates, for the purpose of geographic data reporting, its revenue based upon the location of the contracting subsidiary. Total revenue by geographic area was as follows:

	Three months ended September 30,				Six months ended September 30,
	2018		2017		2018		2017
Revenue:
United States	$	41,135	$	31,076	$	79,068	$	60,268
United Kingdom		25,114		19,635		49,670		37,502
South Africa		11,014		9,393		22,636		18,174
Other		4,906		2,962		9,199		5,280
Total revenue	$	82,169	$	63,066	$	160,573	$	121,224

The provision for income taxes for the three months ended September 30, 2018 and 2017 was $0.6 million and $0.4 million, respectively, on the loss before income taxes of $(1.4) million and $(0.9) million, respectively. The provision for income taxes for the six months ended September 30, 2018 and 2017 was $1.5 million and $0.9 million, respectively, on the loss before income taxes of $(4.0) million and $(2.4) million, respectively. The provision for income taxes for the three and six months ended September 30, 2018 was primarily attributable to the tax provision provided on the earnings in the Company’s South African entity, partially offset by the tax benefit provided on the loss in the Company’s Israel entity. In addition, during the three months ended September 30, 2018, the Company recorded a discrete tax benefit of $0.4 million for the release of a portion of the Company’s pre-existing U.S. valuation allowance as a result of the Ataata business combination. The provision for income taxes for the three and six months ended September 30, 2017 was primarily attributable to earnings in the Company’s U.S. and South African entities offset by $3.0 million and $4.2 million, respectively in excess tax benefits resulting from share option exercises by employees.

In assessing the Company’s ability to realize its net deferred tax assets, the Company considered various factors including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations to determine whether it is more likely than not that some portion or all of its net deferred tax assets will not be realized. Based upon these factors, the Company has determined that the uncertainty regarding the realization of these assets is sufficient to warrant the need for a full valuation allowance against its net deferred tax assets as of September 30, 2018.

As of September 30, 2018 and March 31, 2018, the Company had liabilities for uncertain tax positions of $6.0 million and $6.2 million, respectively, none of which, if recognized, would impact the Company’s effective tax rate. Interest and penalty charges, if any, related to uncertain tax positions would be classified as income tax expense in the accompanying condensed consolidated statements of operations. As of September 30, 2018 and March 31, 2018, accrued interest or penalties related to uncertain tax positions are immaterial.

During the third quarter of fiscal 2018, the Tax Cuts and Jobs Act (the Act) was enacted in the United States. Additionally, during the third quarter of fiscal 2018, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of US GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. The Company did not adjust any of its provisional estimates during the three months ended September 30, 2018. The Company will continue to refine its calculations as additional analysis is completed during the measurement period. In addition, the Company’s estimates may also be affected as the Company gains a more thorough understanding of changes to the tax law resulting from the passage of the Act. The Company anticipates completing its assessment of the impact of the Act during the third quarter 2019.

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) or other standard setting bodies and adopted by the Company as of the specified effective date.

On April 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606. The core principle of ASU 2014-09 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under legacy GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. See Note 1 for the impact of the adoption on revenue recognition and accounting for costs to obtain a contract.

On April 1, 2018 the Company adopted ASU No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). ASU 2016-01 requires equity investments that do not result in consolidation and are not accounted under the equity method to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to

measure the liability at fair value in accordance with the fair value option for financial instruments; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the financial statements; clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets; and modifies certain fair value disclosure requirements. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements.

On April 1, 2018 the Company adopted ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15). ASU 2016-15 is intended to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows and to eliminate the diversity in practice related to such classifications. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements.

On April 1, 2018 the Company adopted ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (ASU 2016-16). The purpose of ASU 2016-16 is to simplify the income tax accounting of an intra-entity transfer of an asset other than inventory and to record its effect when the transfer occurs. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements.

On April 1, 2018 the Company adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18). ASU 2016-18 requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. The adoption of this standard had no impact on the Company’s condensed consolidated financial statements.

On April 1, 2018 the Company adopted ASU 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of a Business (ASU 2017-01). The amendment changes the definition of a business to assist entities in evaluating when a set of transferred assets and activities constitutes a business. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements.

On April 1, 2018 the Company adopted ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting (ASU 2017-09). This guidance clarifies when companies would apply modification accounting to changes to the terms or conditions of a share-based payment award. The guidance narrows the definition of a modification. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements.

On July 1, 2018, the Company adopted ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-24): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract (ASU 2018-15) on a prospective basis. ASU 2018-15 requires a customer in a cloud computing arrangement that is a service contract (hosting arrangement) to follow the internal use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. See Note 8 for the impact of the adoption.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02). ASU 2016-02 requires a lessee to recognize most leases on the balance sheet but recognize expenses on the income statement in a manner similar to current practice. The update states that a lessee will recognize a lease liability for the obligation to make lease payments and a right-of-use asset for the right to use the underlying assets for the lease term. This ASU is effective for annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The Company intends to adopt ASU 2016-02 on April 1, 2019 utilizing the modified retrospective transition method. The Company is currently in the process of evaluating the impact of ASU 2016-02 on its consolidated financial statements, but expects that it will have a material impact on the Company’s consolidated financial statements, primarily the consolidated balance sheets and related disclosures.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The amendment changes the impairment model for most financial assets and certain other instruments. Entities will be required to use an expected loss model that will result in the earlier recognition of allowances for losses for trade and other receivables, held-to-maturity debt securities, loans, and other instruments. For available-for-sale debt securities with unrealized losses, the losses will be recognized as allowances rather than as reductions in the amortized cost of the securities. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted. The Company is currently in the process of evaluating the impact and timing of adoption of the ASU 2016-13 on its condensed consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment (ASU 2017-04). The standard eliminates the second step in the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill. The standard is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently in the process of evaluating the impact and timing of adoption of the ASU 2017-04 on its condensed consolidated financial statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of our operations should be read in conjunction with the (1) unaudited condensed consolidated financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q and (2) the audited consolidated financial statements and notes thereto and management’s discussion and analysis of financial condition and results of operations for the fiscal year ended March 31, 2018, included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission, or the SEC, on May 29, 2018. This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, or the “Exchange Act.” These statements are often identified by the use of words such as “may,” “will,” “expect,” “believe,” “anticipate,” “intend,” “could,” “estimate,” or “continue,” and similar expressions or variations. Such forward-looking statements are subject to risks, uncertainties and other factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified herein, and those discussed in the section titled “Risk Factors” in this Quarterly Report on Form 10-Q and set forth in our other SEC filings, including our Annual Report on Form 10-K filed with the SEC on May 29, 2018. We disclaim any obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

We are a leading global provider of next generation cloud security and risk management services for corporate information and email. Our fully-integrated suite of proprietary cloud services protects customers of all sizes from the significant business and data security risks to which their email system exposes them. We protect customers from today’s rapidly changing threat landscape where email has become a powerful attack vector and data leak concern. We also mitigate the significant business disruption that email failure or downtime causes. In addition, our archiving services secure, store and manage critical corporate communications and information to address growing compliance, regulatory and e-discovery requirements and enable customers to use this increasing archive of information to improve employee productivity.

We operate our business on a software-as-a-service, or SaaS, model with renewable annual subscriptions. Customers enter into annual and multi-year contracts to utilize various components of our services. Our subscription fee includes the use of the selected service and technical support. We believe our technology, subscription-based model, and customer support have led to our high revenue retention rate, which has helped us drive our strong revenue growth. We have historically experienced significant revenue growth from our existing customer base as they renew our services and purchase additional products.

We market and sell our services to organizations of all sizes across a broad range of industries. As of September 30, 2018, we provided our services to approximately 32,200 customers and protected millions of their employees across the world. We generate sales through our network of channel partners as well as through our direct sales force. Our growth and future success depends on our ability to expand our customer base and to sell additional services to our existing customers.

In the six months ended September 30, 2018, we generated 51% of our revenue outside of the United States, with 31% generated from the United Kingdom, 14% from South Africa and 6% from the rest of the world. Our most significant growth market is the United States. We also believe that there is significant opportunity in our other existing markets. We intend to make significant investments in sales and marketing to continue expanding our customer base in our target markets.

We were founded in 2003 with a mission to make email safer and better, and to transform the way organizations protect, store and access their email and corporate information. Our first service, Mimecast Email Security, which we launched in late 2003, was quickly followed by Mimecast Email Continuity. In 2004, we added Mimecast Enterprise Information Archiving. These three services generate a large proportion of our revenue today. In 2006, we started the development of our proprietary cloud architecture, which we refer to as Mime | OS™. We believed early on that investing in the development of our own cloud operating system was a strategic requirement that would enable us to integrate and scale our services. Mimecast Large File Send was released in 2013 and was followed by Mimecast Targeted Threat Protection in 2014, our advanced persistent threat protection service. In 2014, we also released comprehensive risk mitigation technologies specifically for Microsoft Office 365®, and in 2015, we released Mimecast Secure Messaging. In 2016 and 2017, we announced the newest aspects of our Targeted Threat Protection service, Impersonation Protect and Internal Email Protect, respectively. Additionally, in 2017, we acquired technology from iSheriff, Inc. to provide our customers additional real-time email threat intelligence and detection expertise complementing our existing portfolio of email security, continuity and archiving solutions. In fiscal 2018, we announced Sync & Recover, a service to enable fast mailbox recovery in the event omnipresent attackers are successful in penetrating an organization. In fiscal 2019, Mimecast opened an early adopter program for new web security services that provide an easy to deploy and use DNS solution alongside Mimecast’s core email offering. With the acquisition of ATAATA, Inc., or Ataata, and Solebit LABS, Ltd., or Solebit, Mimecast entered the security awareness training market and added leading threat detection technology.

We believe that the growth of our business and our future success are dependent upon a number of key factors, including the following:

Acquisition of new customers. We employ a sales strategy that focuses on acquiring new customers through our direct sales force and network of channel partners, and selling additional products to existing customers. Acquiring new customers is a key element of our continued success, growth opportunity and future revenue. We have invested in and intend to continue to invest in our direct sales force and channel partners. During the twelve months ended September 30, 2018, our customer base increased by approximately 4,000 organizations.

Further penetration of existing customers. Our direct sales force, together with our channel partners and dedicated customer experience team, seek to generate additional revenue from our existing customers by adding more employees and selling additional services. We continue to believe a significant opportunity exists for us to sell additional services to current customers as they experience the benefits of our services and we address additional business use cases.

Investment in growth. We are expanding our operations, increasing our headcount and developing software to both enhance our current offerings and build new features. We expect our total operating expenses to increase, particularly as we continue to expand our sales operations, marketing activities and research and development team. We intend to continue to invest in our sales, marketing and customer experience organizations to drive additional revenue and support the growth of our customer base. Investments we make in our sales and marketing and research and development organizations will occur in advance of experiencing any benefits from such investments. For the year ending March 31, 2019, we plan to continue increasing the size of our sales force and to invest in the development of additional marketing content. We have increased and plan to continue to increase the size of our research and development team.

Currency fluctuations. We conduct business in the United States and in other countries in North America, the United Kingdom and other countries in Europe, South Africa and other countries in Africa, and also Australia. As a result, we are exposed to risks associated with fluctuations in currency exchange rates, particularly between the U.S. dollar, the British pound and the South African rand. In the six months ended September 30, 2018, 51% of our revenue was denominated in U.S. dollars, 29% in British pounds, 14% in South African rand and 6% in other currencies. Given that our functional currency and the functional currency of our subsidiaries is the local currency of each entity but our reporting currency is the U.S. dollar, devaluations of the British pound, South African rand and other currencies relative to the U.S. dollar impacts our profitability.

In addition to traditional financial metrics, such as revenue and revenue growth trends, we monitor several other key performance indicators to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies. The key performance indicators that we monitor are as follows:

	Three months ended September 30,						Six Months Ended September 30,
	2018			2017			2018			2017
	(dollars in thousands)
Revenue constant currency growth rate (1)		32	%		41	%		32	%		42	%
Revenue retention rate		110	%		111	%		110	%		111	%
Total customers (2)		32,200			28,200			32,200			28,200
Gross profit percentage		73	%		74	%		73	%		74	%
Adjusted EBITDA (1)	$	12,312		$	6,652		$	22,270		$	11,796

Revenue constant currency growth rate. We believe revenue constant currency growth rate is a key indicator of our operating results. We calculate revenue constant currency growth rate by translating revenue from entities reporting in foreign currencies into U.S. dollars using the comparable foreign currency exchange rates from the prior fiscal period. For further explanation of the uses and limitations of this measure and a reconciliation of our revenue constant currency growth rate to revenue, as reported, the most directly comparable U.S. GAAP measure, please see “—Reconciliation of Non-GAAP Financial Measures” below. As our total revenue grows, we expect our constant currency growth rate will decline as the incremental growth from period to period is expected to represent a smaller percentage of total revenue as compared to the prior period.

Revenue retention rate. We believe that our ability to retain customers is an indicator of the stability of our revenue base and the long-term value of our customer relationships. Our revenue retention rate is driven by our customer renewals and upsells. We calculate our revenue retention rate by annualizing constant currency revenue recorded on the last day of the measurement period for only those customers in place throughout the entire measurement period. We include add-on, or upsell, revenue from additional employees and services purchased by existing customers. We divide the result by revenue on a constant currency basis on the first day of the measurement period for all customers in place at the beginning of the measurement period. The measurement period is the trailing twelve months. The revenue on a constant currency basis is based on the average exchange rates in effect during the respective period. We expect our revenue retention rate in fiscal 2019 periods to remain relatively consistent with fiscal 2018 periods.

Total customers. We believe the total number of customers is a key indicator of our financial success and future revenue potential. We define a customer as an entity with an active subscription contract as of the measurement date. A customer is typically a parent company or, in a few cases, a significant subsidiary that works with us directly. We expect to continue to grow our customer base through the addition of new customers in each of our markets.

Gross profit percentage. Gross profit percentage is calculated as gross profit divided by revenue. Our gross profit percentage has been relatively consistent over the past three years, however, it has fluctuated on a quarterly basis due to timing of the addition of hardware and employees to serve our growing customer base. More recently, gross profit has also included amortization of intangible assets related to acquired businesses. Gross profit fluctuates due to timing of the addition of hardware and employees to serve our growing customer base. We provide our services in each of the regions in which we operate. Costs related to supporting and hosting our product offerings and delivering our services are incurred in the region in which the related revenue is recognized. As a result, our gross profit percentage in actual terms is consistent with gross profit on a constant currency basis.

Adjusted EBITDA. We believe that Adjusted EBITDA is a key indicator of our operating results. We define Adjusted EBITDA as net (loss) income, adjusted to exclude: depreciation, amortization, disposals and impairments of long-lived assets, acquisition-related gains and expenses, share-based compensation expense, restructuring expense, interest income and interest expense, the provision for income taxes and foreign exchange (expense) income. Adjusted EBITDA also includes rent paid in the period related to locations that are accounted for as build-to-suit facilities. For further explanation of the uses and limitations of this measure and a reconciliation of our Adjusted EBITDA to the most directly comparable U.S. GAAP measure, net (loss) income, please see “—Reconciliation of Non-GAAP Financial Measures” below. We expect that our Adjusted EBITDA will continue to increase; however, we expect that our operating expenses will also increase in absolute dollars as we focus on expanding our sales and marketing teams and growing our research and development capabilities.

In order to determine how our business performed exclusive of the effect of foreign currency fluctuations, we compare the percentage change in our revenue from one period to another using a constant currency. To determine the revenue constant currency growth rate for the fiscal periods below, revenue from entities reporting in foreign currencies was translated into U.S. dollars using the comparable prior period’s foreign currency exchange rates. For example, the average rates in effect for the three months ended September 30, 2017 were used to convert revenue for the three months ended September 30, 2018 and the revenue for the comparable prior period ended September 30, 2017, rather than the actual exchange rates in effect during the respective period. Revenue constant currency growth rate is a non-GAAP financial measure. A reconciliation of this non-GAAP measure to its most directly comparable U.S. GAAP measure for the respective periods can be found in the table below:

	Three months ended September 30,						Six months ended September 30,
	2018			2017			2018			2017
	(dollars in thousands)
Reconciliation of Revenue Constant Currency Growth Rate:
Revenue, as reported	$	82,169		$	63,066		$	160,573		$	121,224
Revenue year-over-year growth rate, as reported		30	%		42	%		32	%		41	%
Estimated impact of foreign currency fluctuations		2	%		(1	)%		—	%		1	%
Revenue constant currency growth rate		32	%		41	%		32	%		42	%

The impact of foreign exchange rates is highly variable and difficult to predict. We use revenue constant currency growth rate to show the impact from foreign exchange rates on the current period revenue growth rate compared to the prior period revenue growth rate using the prior period’s foreign exchange rates. In order to properly understand the underlying business trends and performance of our ongoing operations, we believe that investors may find it useful to consider the impact of excluding changes in foreign exchange rates from our revenue growth rate.

We believe that presenting this non-GAAP financial measure in this Quarterly Report on Form 10-Q provides investors greater transparency to the information used by our management for financial and operational decision-making and allows investors to see our results “through the eyes” of management. We also believe that providing this information better enables our investors to understand our operating performance and evaluate the methodology used by management to evaluate and measure such performance.

However, this non-GAAP measure should not be considered in isolation or as a substitute for our financial results prepared in accordance with U.S. GAAP. For example, revenue constant currency growth rates, by their nature, exclude the impact of foreign exchange, which may have a material impact on U.S. GAAP revenue. Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.

Adjusted EBITDA is a non-GAAP financial measure that we define as net (loss) income, adjusted to exclude: depreciation, amortization, disposals and impairments of long-lived assets, acquisition-related gains and expenses, share-based compensation expense, restructuring expense, interest income and interest expense, the provision for income taxes and foreign exchange (expense) income. Adjusted EBITDA also includes rent paid in the period related to locations that are accounted for as build-to-suit facilities.

We believe that Adjusted EBITDA provides investors and other users of our financial information consistency and comparability with our past financial performance, facilitates period-to-period comparisons of operations and facilitates comparisons with our peer companies, many of which use a similar non-GAAP financial measure to supplement their U.S. GAAP results.

We use Adjusted EBITDA in conjunction with traditional U.S. GAAP operating performance measures as part of our overall assessment of our performance, for planning purposes, including the preparation of our annual operating budget, to evaluate the effectiveness of our business strategies, to communicate with our board of directors concerning our financial performance and for establishing incentive compensation metrics for executives and other senior employees.

We do not place undue reliance on Adjusted EBITDA as a measure of operating performance. This non-GAAP measure should not be considered as a substitute for other measures of financial performance reported in accordance with U.S. GAAP. There are limitations to using a non-GAAP financial measure, including that other companies may calculate this measure differently than we do, that it does not reflect our capital expenditures or future requirements for capital expenditures and that it does not reflect changes in, or cash requirements for, our working capital.

The discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates, assumptions and judgments that can have a significant impact on the reported amounts of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of our financial statements. We base our estimates, assumptions and judgments on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. On a regular basis, we evaluate our estimates, assumptions and judgments and make changes accordingly.

We believe that the estimates, assumptions and judgments involved in revenue recognition, deferred revenue, share-based compensation and accounting for income taxes have the greatest potential impact on our consolidated financial statements, and consider these to be our critical accounting policies. Historically, our estimates, assumptions and judgments relative to our critical accounting policies have not differed materially from actual results. For further information on our critical and other significant accounting policies, see the notes to the condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K filed with the SEC on May 29, 2018. See Note 1 to the unaudited condensed consolidated financial statements of this Quarterly Report on Form 10-Q for changes to our significant accounting policies since the year ended March 31, 2018.

See Note 18 to the unaudited condensed consolidated financial statements of this Quarterly Report on Form 10-Q.

We generate substantially all of our revenue from subscription fees paid by customers accessing our cloud services and by customers purchasing additional support beyond the standard support that is included in our basic subscription fees. A small portion of our revenue consists of related professional services and other revenue, which consists primarily of performance obligations related to set-up, ingestion and training fees.

We generally license our services on a price per employee basis under annual contracts. In some instances, we receive upfront payments which are determined to be material rights to a discount upon renewal. In these instances, we recognize revenue related to the upfront payment over the estimated customer benefit period, which has been determined to be six years.

We serve approximately 32,200 customers in multiple industries, and our revenue is not concentrated with any single customer or industry. For the three and six months ended September 30, 2018 and 2017, no single customer accounted for more than 1% of our revenue, and our largest ten customers accounted for less than 10% of our revenue in aggregate.

Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met.

We recognize revenue ratably on a straight-line basis over the subscription term, which begins when we have given the customer access to our SaaS solutions. Our subscription contracts are typically one year in duration and do not contain refund-type provisions.

Our professional services contracts are recognized based on out-put measures of performance.

Cost of revenue primarily consists of expenses related to supporting and hosting our product offerings and delivering our professional services. These costs consist primarily of personnel and related costs including salaries, benefits, bonuses and share-based compensation expense related to the management of our data centers, our customer support team and our professional services team. In addition to these expenses, we incur third-party service provider costs such as data center and networking expenses, allocated overhead costs, depreciation expense and amortization expense related to intangible assets. We allocate overhead costs, such as rent and facility costs, information technology costs and employee benefit costs to all departments based on headcount. As such, general overhead expenses are reflected in cost of revenue and each operating expense category.

We expect our cost of revenue to increase in absolute dollars due to expenditures related to the purchase of hardware, expansion and support of our data center operations and customer support teams. We also expect that cost of revenue as a percentage of revenue will decrease over time as we are able to achieve economies of scale in our business, although it may fluctuate from period to period depending on the timing of significant expenditures. To the extent that our customer base grows, we intend to continue to invest additional resources in expanding the delivery capability of our products and other services. The timing of these additional expenses could affect our cost of revenue, both in terms of absolute dollars and as a percentage of revenue in any particular quarterly or annual period.

Research and development expenses consist primarily of personnel and related costs, including salaries, benefits, bonuses, share-based compensation expense, costs of server usage by our developers and allocated overhead costs. We expense all research and development costs as they are incurred. We have focused our efforts on developing new versions of our SaaS technology with expanded features. Our technology is constantly being refined and, as such, we do not capitalize development costs. We believe that continued investment in our technology is important for our future growth. As a result, we expect research and development expenses to increase in absolute dollars as we make further substantial investments in developing our Mime | OS™ platform, improving our existing services and creating new features and products. Research and development expenses as a percentage of total revenue may fluctuate on a quarterly basis but we expect it to increase in the coming fiscal year as a result of the expected investments noted above.

Sales and marketing expenses consist primarily of personnel and related costs, including salaries, benefits, bonuses, commissions and share-based compensation expense. In addition to these expenses, we incur costs related to marketing and promotional events, online marketing, product marketing and allocated overhead costs. We expense all costs as they are incurred, excluding sales commissions identified as incremental costs to obtain a contract, which are capitalized and amortized over the life of our customers, which we estimate to be six years. Sales and marketing expenses increased in the three and six months ended September 30, 2018 as we continued to expand our sales and marketing efforts globally, and particularly in the United States. We expect that our sales and marketing expenses will continue to increase substantially in the year ending March 31, 2019. New sales personnel require training and may take several months or more to achieve productivity; as such, the costs we incur in connection with the hiring of new sales personnel in a given period are not typically offset by increased revenue in that period and may not result in new revenue if these sales personnel fail to become productive. We expect to increase our investment in sales and marketing as we add new services, which will increase these expenses in absolute dollars. Over the long term, we believe that sales and marketing expenses as a percentage of revenue will decrease, but will vary depending upon the mix of revenue from new and existing customers, as well as changes in the productivity of our sales and marketing programs.

General and administrative expenses consist primarily of personnel and related expenses for executive, legal, finance, information technology and human resources functions, including salaries, benefits, incentive compensation and share-based compensation expense, in addition to the costs associated with professional fees, insurance premiums, other corporate expenses and allocated overhead costs. We expect general and administrative expenses to increase in absolute dollars as we continue to incur additional personnel and professional services costs in order to support business growth as well as meeting the compliance requirements of operating as a public company, including those costs incurred in connection with Section 404 of the Sarbanes-Oxley Act, costs associated with the loss of our status as a foreign private issuer, and costs associated with acquisitions, funding transactions, the adoption of new accounting standards, including Accounting Standards Codification (ASC) 606, Revenue Recognition, and Accounting Standards Update (ASU) 2016-02, Leases, among others. Over the long term, we believe that general and administrative expenses as a percentage of revenue will decrease.

Interest income includes interest income earned on our cash, cash equivalents and investments balances. We expect interest income to vary each reporting period depending on our average cash, cash equivalents and investments balances during the period and market interest rates.

Interest expense consists primarily of interest expense associated with our construction financing lease obligations, capital leases and our long-term debt. We expect interest expense to increase in fiscal 2019 primarily due to the Credit Facility entered into in July 2018.

Foreign exchange expense and other, net consists primarily of foreign exchange fluctuations related to short-term intercompany accounts and foreign currency exchange gains and losses related to transactions denominated in currencies other than the functional currency for each of our subsidiaries. We expect our foreign currency exchange gains and losses to continue to fluctuate in the future as foreign currency exchange rates change, however, we expect foreign currency exchange gains and losses could be less significant in the fiscal year ending March 31, 2019 as compared to the fiscal year ended March 31, 2018 due to the capitalization and repayment of certain intercompany balances during fiscal 2018.

We operate in several tax jurisdictions and are subject to taxes in each country or jurisdiction in which we conduct business. We account for income taxes in accordance with the asset and liability method. Under this method, deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases for assets and liabilities using statutory rates. In addition, this method requires a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Our provision for income taxes for the three and six months ended September 30, 2018 is primarily attributable to the tax provision provided on the earnings in the Company’s South African entity, partially offset by the tax benefit provided on the loss in our Israeli entity. In addition, during the three months ended September 30, 2018, we recorded a discrete tax benefit of $0.4 million for the release of a portion of our pre-existing U.S. valuation allowance as a result of the Ataata business combination. The provision for income taxes for the three and six months ended September 30, 2017 is primarily attributable to earnings in our U.S. and South African entities offset by $3.0 million and $4.2 million, respectively, in excess tax benefits resulting from share option exercises by employees.

We have operations in jurisdictions other than the United States and generate revenue and incur expenditures in currencies other than the U.S. dollar. The following information shows the effect on certain components of our condensed consolidated statements of operations data for each of the periods indicated below based on a 10% increase or decrease in foreign currency exchange rates assuming that all foreign currency exchange rates move in the same direction at the same time:

	Three months ended September 30,				Six months ended September 30,

Revenue increased $19.1 million in the three months ended September 30, 2018 compared to the three months ended September 30, 2017. The increase in revenue was primarily attributable to increases in new customers, including approximately 4,000 new customers added since September 30, 2017, a full quarter of revenue related to new customers added during the first quarter of fiscal 2018, and additional revenue from customers that existed as of September 30, 2017. Revenue for the three months ended September 30, 2018 compared to the three months ended September 30, 2017 was negatively impacted by approximately $1.2 million primarily as a result of the strengthening of the U.S. dollar relative to the South African rand and British pound.

Cost of revenue increased $5.4 million in the three months ended September 30, 2018 compared to the three months ended September 30, 2017, which was primarily attributable to increases in personnel-related costs of $1.6 million, depreciation expense of $0.9 million, amortization of intangibles of $0.9 million, information technology and facilities costs of $0.8 million, professional services costs of $0.5 million and data center costs of $0.2 million. Cost of revenue for the three months ended September 30, 2018 compared to the three months ended September 30, 2017 was positively impacted by approximately $0.3 million primarily as a result of the strengthening of the U.S. dollar relative to the South African rand. Personnel-related costs increased primarily as a result of salaries and benefits associated with increased headcount, depreciation expense increased primarily as a result of increased capital expenditures in support of our expanding infrastructure, the increase in amortization of intangibles is primarily as a result of amortization of capitalized software, the increase in information technology and facility costs is primarily a result of increased headcount, professional services costs increased primarily due to data extraction vendor costs and data center costs increased primarily as a result of the increase in our customer base.

As a result of changes in foreign exchange rates, gross profit decreased in absolute dollars by approximately $0.9 million for the three months ended September 30, 2018 compared to the three months ended September 30, 2017. Excluding the impact of changes in foreign currency exchange rates, gross profit as a percentage of revenue remained consistent as costs related to supporting and hosting our product offerings and delivering our services are primarily incurred in the region in which the related revenue is recognized.

Research and development expenses increased $5.9 million in the three months ended September 30, 2018 compared to the three months ended September 30, 2017, which was primarily attributable to increases in personnel-related costs of $3.7 million, share-based compensation expense of $1.0 million and information technology and facilities costs of $0.4 million. Personnel-related costs increased primarily as a result of salaries and benefits associated with increased headcount. Share-based compensation expense increased primarily as a result of share option grants since the prior year. Information technology and facility costs increased primarily as a result of increased headcount.

Sales and marketing expenses increased $4.6 million in the three months ended September 30, 2018 compared to the three months ended September 30, 2017, which was primarily attributable to increases in personnel-related costs of $1.6 million, information technology and facilities costs of $1.4 million, professional services costs of $1.0 million, share-based compensation expense of $0.8 million. Total sales and marketing expenses for the three months ended September 30, 2018 compared to the three months ended September 30, 2017 were positively impacted by approximately $0.4 million primarily as a result of the strengthening of the U.S. dollar relative to the South African rand. Personnel-related costs increased primarily as a result of salaries and benefits associated with increased headcount. Information technology and facility costs increased primarily as a result of increased headcount. Professional services costs increased primarily due to consulting fees. Share-based compensation expense increased primarily as a result of share option grants since the prior year.

General and administrative expenses increased $3.8 million in the three months ended September 30, 2018 compared to the three months ended September 30, 2017, which was primarily attributable to increases in personnel-related costs of $1.7 million, share-based compensation of $0.9 million, professional services of $0.8 million and information technology and facilities costs of $0.5 million. Personnel-related costs increased primarily as a result of salaries and benefits associated with increased headcount. Share-based compensation expense increased primarily as a result of share option grants since the prior year. Professional services increased primarily due to acquisition-related costs.

In the second quarter of fiscal 2019, we recorded a revision to restructuring expense of $0.2 million related to the exit of our Watertown, Massachusetts corporate office space, which occurred in the fourth quarter of fiscal 2018.

Other income (expense) increased $0.1 million in the three months ended September 30, 2018 compared to the three months ended September 30, 2017, which was primarily attributable to an increase of $1.5 million in interest expense primarily due to interest expense associated with our construction financing lease obligations and senior secured term loan, partially offset by a decrease in foreign exchange expense of $0.6 million, sublease income of $0.3 million, gain on previously held asset related to the Solebit acquisition of $0.3 million and an increase in interest income on investments of $0.2 million.

The provision for income taxes increased by $0.2 million in the three months ended September 30, 2018 compared to the three months ended September 30, 2017. The increase in the provision for income taxes is primarily attributable to increased earnings in our South African entity, partially offset by the tax benefit provided on the loss in our Israeli entity and the discrete release in valuation allowance against a portion of our pre-existing U.S. deferred tax assets as a result of the Ataata business combination.

Revenue increased $39.4 million in the six months ended September 30, 2018 compared to the six months ended September 30, 2017. The increase in revenue was primarily attributable to increases in new customers, including approximately 4,000 new customers added since September 30, 2017, a full period of revenue related to new customers added during the first six months of fiscal 2018, and additional revenue from customers that existed as of September 30, 2017. Revenue for the six months ended September 30, 2018 compared to the six months ended September 30, 2017 was positively impacted by approximately $1.0 million primarily as a result of the weakening of the U.S. dollar relative to the British pound.

Cost of revenue increased $11.1 million in the six months ended September 30, 2018 compared to the six months ended September 30, 2017, which was primarily attributable to increases in personnel-related costs of $3.3 million, depreciation expense of $2.2 million, the increase in information technology and facilities costs of $1.7 million, amortization of intangibles of $1.6 million, professional services costs of $0.9 million and data center costs of $0.7 million. Cost of revenue for the six months ended September 30, 2018 compared to the six months ended September 30, 2017 was negatively impacted by approximately $0.3 million primarily as a result of the weakening of the U.S. dollar relative to the British pound.

The provision for income taxes increased by $0.6 million in the six months ended September 30, 2018 compared to the six months ended September 30, 2017. The increase in the provision for income taxes is primarily attributable to increased earnings in our South African entity, partially offset by the tax benefit provided on the loss in our Israeli entity and the discrete release in valuation allowance against a portion of our pre-existing U.S. deferred tax assets as a result of the Ataata business combination.

Our principal sources of liquidity are cash and cash equivalents, investments and accounts receivable. The following table shows net cash provided by operating activities, net cash (used in) provided by investing activities, and net cash provided by financing activities for the six months ended September 30, 2018 and 2017:

In November 2015, we raised net proceeds of $68.3 million in our initial public offering, or IPO. Prior to our IPO, we financed our operations primarily through private placements of equity and borrowings from our primary bank lender. In the years ended March 31, 2018 and 2017, we incurred operating losses of $7.0 million and $10.4 million, respectively. While we expect to generate an operating loss in the year ending March 31, 2019, we expect to continue to generate positive cash flows from operating activities. In the year ending March 31, 2019, we plan to continue to invest in the development and expansion of our Mime | OS™ platform to improve on our existing solutions and to provide more products and capabilities to our customers. We will also continue to invest in sales and marketing activities aimed at obtaining new customers and selling more services to our existing customers. Investments in capital expenditures in the year ended March 31, 2018 were $34.5 million of which $24.5 million related to the expansion of our grid architecture. With the exception of the $3.8 million we invested in the development of our German data centers, we expect that this level of investment will be consistent in the year ending March 31, 2019.

As of September 30, 2018 and March 31, 2018, we had cash, cash equivalents and investments of $144.4 million and $137.2 million, respectively. Based on our current operating plan, we believe that our current cash and cash equivalents, investments and operating cash flows will be sufficient to fund our operations for at least the next twelve months. Our future capital requirements may vary materially from those planned and will depend on certain factors, such as, our growth and our operating results. If we require additional capital resources to grow our business or to acquire complementary technologies and businesses in the future, we may seek to sell additional equity or raise funds through debt financing or other sources. We may also seek to invest in or acquire complementary businesses, applications or technologies, any of which could also require us to seek additional equity or debt financing. We cannot provide assurance that additional financing will be available at all or on terms favorable to us. We had no material commitments for capital expenditures as of September 30, 2018 or March 31, 2018.

On July 23, 2018, we entered into a credit agreement, or the Credit Agreement, by and among us, certain of our subsidiaries, as guarantors, certain financial institutions, as lenders, and JPMorgan Chase Bank, N.A., as administrative agent, or the Administrative Agent. The Credit Agreement provides us with a $100.0 million senior secured term loan, and a $50.0 million senior secured revolving credit facility, or collectively, the Credit Facility, which shall be available to fund working capital and for other corporate purposes, including to finance permitted acquisitions and investments. Interest under the Credit Facility accrues at a rate between LIBOR plus 1.375% and LIBOR plus 1.875%, based on the Company’s ratio of indebtedness to earnings before interest, taxes, depreciation, amortization and certain other adjustments, or Consolidated EBITDA. Based on this ratio, the current interest rate at September 30, 2018 under the Credit Facility is LIBOR plus 1.625%. The term of the Credit Facility is five years, maturing on July 23, 2023. At the time we entered into the Credit Agreement, we had no existing debt.

The Credit Facility has financial covenants that require us to maintain a Consolidated Secured Leverage Ratio, commencing on September 30, 2018, of not more than 3.00 to 1.00 for the four consecutive fiscal quarter period ending on the last day of each fiscal quarter, or the Reference Period, with a step-up to 3.50 to 1.00 for any four-quarter period in which we consummate a permitted acquisition having an aggregate purchase price in excess of $25.0 million. We must also maintain a Consolidated Interest Expense Ratio of 3.00 to 1.00 commencing on September 30, 2018 and for each Reference Period thereafter. For purposes of the covenants, “Consolidated Secured Leverage Ratio” generally refers to the ratio of Consolidated Funded Debt that is secured by a lien on assets of us or our subsidiaries to Consolidated EBITDA. “Consolidated Funded Debt” generally refers to borrowed money, debt instruments, capital leases, deferred purchase price of property or services (excluding accounts payable in the ordinary course of business), and earn outs that are due and payable. “Consolidated Interest Expense Ratio” generally refers to the ratio of Consolidated EBITDA to cash interest expense with respect to indebtedness, with certain exclusions. The Company was in compliance with all covenants as of September 30, 2018 and believes it is reasonably expected to be in compliance over next 12 months.

The Credit Agreement contains customary affirmative covenants for transactions of this type and other affirmative covenants agreed to by the parties, including, among others, the provision of annual and quarterly financial statements and compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters. The Credit Agreement contains customary negative covenants, including, among others, restrictions on the incurrence of certain indebtedness, granting of liens, making investments and acquisitions, merger and consolidations, paying dividends, entering into affiliate transactions and asset sales. The Credit Agreement also provides for a number of customary events of default, including, among others, payment, bankruptcy, covenant, representation and warranty, change of control and judgment defaults.

All obligations under the Credit Agreement are unconditionally guaranteed by all of our material direct and indirect subsidiaries organized under the laws of the United States, the United Kingdom, the Bailiwick of Jersey, and other jurisdictions agreed to us and the Administrative Agent, with certain exceptions. These guarantees are secured by substantially all of the present and future property and assets of the guarantors, with certain exclusions.

For the six months ended September 30, 2018, cash provided by operating activities was $29.1 million. The primary factors affecting our operating cash flows during the period were our net loss of $5.5 million, adjusted for non-cash items of $14.3 million for depreciation and amortization of our property, equipment and intangible assets, $11.3 million of share-based compensation expense and $2.9 million in amortization of deferred contract costs. The primary drivers of the changes in operating assets and liabilities were $6.6 million increase in deferred revenue, a $3.3 million decrease in prepaid expenses, a $3.0 million increase in accounts payable and other current assets and a $2.5 million decrease in accounts receivable, partially offset by a $7.8 million increase in deferred contract costs.

For the six months ended September 30, 2017, cash provided by operating activities was $19.0 million. The primary factors affecting our operating cash flows during the period were our net loss of $3.2 million, adjusted for non-cash items of $7.9 million for depreciation and amortization of our property, equipment and intangible assets, $5.6 million of share-based compensation expense and $0.8 million in unrealized foreign currency losses on foreign denominated transactions, primarily intercompany balances. The primary drivers of the changes in operating assets and liabilities were a $7.4 million increase in deferred revenue, a $1.5 million increase in accounts payable and a $1.0 million increase in accrued expenses and other liabilities, partially offset by a $1.8 million increase in prepaid expenses and other current assets.

Cash used in investing activities of $91.2 million for the six months ended September 30, 2018 consisted of $108.9 million in payments for acquisitions, $15.8 million in purchases of property, equipment and capitalized software and $7.0 million in purchases of investments, partially offset by $40.5 million in maturities of investments. Cash provided by investing activities of $0.6 million for the six months ended September 30, 2017 consisted of $24.5 million in purchases of investments and $13.4 million in purchases of property, equipment and capitalized software partially offset by $38.5 million in maturities of investments.

Our capital expenditures in each period were primarily associated with computer equipment and software purchased in support of our expanding infrastructure. Additionally, in the six months ended September 30, 2018, we had purchases of $0.7 million in leasehold improvements and office equipment related to the fit-out of our new facilities.

Cash provided by financing activities of $105.1 million for the six months ended September 30, 2018 was due to proceeds from issuance of debt of $97.7 million and issuance of ordinary shares of $9.2 million partially offset by payments on construction financing lease obligations of $0.8 million, payments on debt of $0.6 million and payments on capital lease obligations of $0.4 million.

Cash provided by financing activities of $5.2 million for the six months ended September 30, 2017 was due to proceeds from exercises of share options of $6.4 million partially offset by payments on debt of $1.1 million and payments on capital lease obligations of $0.2 million.

As of September 30, 2018, we had net operating loss carryforwards in the U.K., U.S. federal and state, Australia, Germany and Israel. U.S. federal net operating losses generated through the fiscal year ending March 31, 2017 expire at various dates through 2037 while U.S. federal net operating losses generating after March 31, 2017 do not expire. The U.S. state net operating loss carryforwards expire at various dates through 2038. Net operating loss carryforwards in the U.K., Australia, Germany and Israel do not expire. As of September 30, 2018, we had a U.K. income tax credit carryforward that does not expire. As of September 30, 2018, we had Israel income tax credits that expire in 2024 and 2025.

In assessing our ability to realize our net deferred tax assets, we considered various factors including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations, to determine whether it is more likely than not that some portion or all of our net deferred tax assets will not be realized. Based upon these factors, we have determined that the uncertainty regarding the realization of these assets is sufficient to warrant the need for a full valuation allowance against our net deferred tax assets.

Up to and including the six months ended September 30, 2018, we have not had any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As a result, we are not exposed to related financing, liquidity, market or credit risks that could arise if we had engaged in those types of arrangements.

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency rates, although we also have some exposure due to potential changes in inflation or interest rates. We do not hold financial instruments for trading purposes.

Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the British pound and South African rand. Percentage of revenue and expenses in foreign currency is as follows:

Percentages of revenue and expenses denominated in foreign currency are as follows:

As of September 30, 2018 and March 31, 2018, we had $33.0 million and $35.3 million, respectively, of receivables denominated in currencies other than the U.S. dollar. We also maintain cash accounts denominated in currencies other than the local currency, which exposes us to foreign exchange rate movements. As of September 30, 2018 and March 31, 2018, we had $19.7 million and $20.4 million, respectively, of cash denominated in currencies other than the U.S. dollar. As of September 30, 2018, cash denominated in British pounds and South African rand was $8.6 million and $7.3 million, respectively. As of March 31, 2018, cash denominated in British pounds and South African rand was $6.0 million and $10.7 million, respectively.

In addition, although our foreign subsidiaries have intercompany accounts that are eliminated upon consolidation, these accounts expose us to foreign currency exchange rate fluctuations. Exchange rate fluctuations on short-term intercompany accounts are recorded in our condensed consolidated statements of operations under “foreign exchange expense and other, net.”

Currently, our largest foreign currency exposures are the British pound and South African rand. Relative to foreign currency exposures existing at September 30, 2018, significant movements in foreign currency exchange rates may expose us to significant losses in earnings or cash flows or significantly diminish the fair value of our foreign currency financial instruments. For the six months ended September 30, 2018, we estimate that a 10% unfavorable movement in foreign currency exchange rates against the U.S. dollar would have decreased revenue by $7.9 million, decreased expenses by $7.8 million and would have increased our loss from operations by $0.1 million. For the six months ended September 30, 2017, we estimate that a 10% unfavorable movement in foreign currency exchange rates against the U.S. dollar would have decreased revenue by $5.9 million, decreased expenses by $5.8 million and would have increased our loss from operations by $0.1 million. The estimates used assume that all currencies move in the same direction at the same time and the ratio of non-U.S. dollar denominated revenue and expenses to U.S. dollar denominated revenue and expenses does not change from current levels. All of the potential changes noted above are based on sensitivity analyses performed on our financial results as of September 30, 2018 and 2017.

Inflationary factors, such as increases in our operating expenses, may adversely affect our results of operations, as our customers typically purchase services from us on a subscription basis over a period of time. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, an increase in the rate of inflation in the future may have an adverse effect on our levels of operating expenses as a percentage of revenue if we are unable to increase the prices for our subscription-based services to keep pace with these increased expenses.

We are exposed to market risk related to changes in interest rates. Our investments primarily consist of short-term investments and money market funds. As of September 30, 2018 and March 31, 2018, we had cash, cash equivalents and investments of $144.4 million and $137.2 million, respectively. The carrying amount of our cash equivalents reasonably approximates fair value, due to the short maturities of these investments. The primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs and the fiduciary control of cash and investments. We do not enter into investments for trading or speculative purposes. Our investments are exposed to market risk due to a fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. Due to the short-term nature of our investment portfolio, we believe only dramatic fluctuations in interest rates would have a material effect on our investments. We do not believe that an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio. As such we do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates.

We entered into the Credit Agreement in July 2018. The Credit Agreement provides us with a $100,000,000 senior secured term loan, and a $50,000,000 senior secured revolving credit facility. Interest under the Credit Facility accrues at a rate between LIBOR plus 1.375% and LIBOR plus 1.875%. We estimate that a 100 basis point increase in the LIBOR rate would result in approximately $1.0 million of additional interest expense over the ensuing twelve-month period under the Credit Facility.

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2018. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act means 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 or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2018, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended September 30, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

From time to time, we may be involved in legal proceedings and subject to claims in the ordinary course of business. Although the results of these proceedings and claims cannot be predicted with certainty, we do not believe the ultimate cost to resolve these matters would individually, or taken together, have a material adverse effect on our business, operating results, cash flows or financial condition. Regardless of the outcome, such proceedings can have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained.

If we are unable to attract new customers and retain existing customers, our business and results of operations will be affected adversely.

To succeed, we must continue to attract new customers and retain existing customers who desire to use our security, continuity and archiving offerings. Acquiring new customers is a key element of our continued success, growth opportunity and future revenue. We will continue to invest in a direct sales force combined with a focused channel strategy designed to serve the various requirements of small, mid-market and large enterprises and to bring new customers onto our cloud architecture. Any failures by us to execute in these areas will negatively impact our business. The rate at which new and existing customers purchase our products depends on a number of factors, including those outside of our control. For example, in the fiscal year ended March 31, 2017, we benefited from the decision by Intel Corporation to end-of-life its McAfee MX Logic email protection product. Our future success also depends on retaining our current customers at acceptable retention levels. Our retention rates may decline or fluctuate as a result of a number of factors, some of which may be outside our control, including competition, customers’ budgeting and spending priorities, and overall general economic conditions. If our customers do not renew their subscriptions for our products and services, our revenue would decline and our business would suffer. In future periods, our total customers and revenue could decline or grow more slowly than we expect

If we are unable to sell additional services and features to our existing customers, our future revenue and operating results will be harmed.

A significant portion of our revenue growth is generated from sales of additional services and features to existing customers. Our future success depends, in part, on our ability to continue to sell such additional services and features to our existing customers. We devote significant efforts to developing, marketing and selling additional services and features and associated support services to existing customers and rely on these efforts for a portion of our revenue. These efforts require a significant investment in building and maintaining customer relationships, as well as significant research and development efforts in order to provide upgrades and launch new services and features. The rate at which our existing customers purchase additional services and features depends on a number of factors, including the perceived need for additional security, continuity and archiving, the efficacy of our current services, the perceived utility of our new offerings, our customers’ IT budgets and general economic conditions. If our efforts to sell additional services and features to our customers are not successful, our future revenues and operating results will be harmed.

Failure to effectively expand our sales and marketing capabilities could harm our ability to acquire new customers and achieve broader market acceptance of our services.

Acquiring new customers and expanding sales to existing customers will depend to a significant extent on our ability to expand our sales and marketing operations. We generate approximately one-third of our revenue from direct sales and we expect to continue to rely on our sales force to obtain new customers and grow revenue from our existing customer base. We expect to expand our sales force in all of our regions and we face a number of challenges in achieving our hiring goals. For instance, there is significant competition for sales personnel with the sales skills and technical knowledge that we require. In addition, training and integrating a large number of sales and marketing personnel in a short period of time requires the allocation of significant internal resources. Our ability to achieve projected growth in revenue in the future will depend, in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel. We invest significant time and resources in training new sales personnel to understand our solutions and growth strategy. In general, new hires require significant training and substantial experience before becoming productive. Our recent hires and planned hires may not become as productive as we require, and we may be unable to hire or retain sufficient numbers of qualified individuals in the future in the markets where we currently operate or where we seek to conduct business. Our growth may be materially and adversely impacted if the efforts to expand our sales and marketing capabilities are not successful or if they do not generate a sufficient increase in revenue.

Our business depends substantially on customers renewing their subscriptions with us. A decline in our customer renewals would harm our future operating results.

In order for us to maintain or improve our operating results, it is important that our customers renew their subscriptions with us when the existing subscription term expires. Although the majority of our customer contracts include auto-renew provisions, our customers have no obligation to renew their subscriptions upon expiration, and we cannot provide assurance that customers will renew subscriptions at the same or higher level of service, if at all. For each of the fiscal periods ended September 30, 2018, 2017 and 2016, our customer retention rate has been consistently greater than 90%] We calculate customer retention rate as the percentage of paying customers on the last day of the relevant period in the prior year who remain paying customers on the last day of the relevant period in the current year. The rate of customer renewals may decline or fluctuate as a result of a number of factors, including our customers’ satisfaction or dissatisfaction with our solutions, the effectiveness of our customer support services, our pricing, the prices of competing products or services, mergers and acquisitions affecting our customer base, or reductions in our customers’ spending levels. If our customers do not renew their subscriptions, or renew on less favorable terms, our revenue may decline, and we may not realize improved operating results from our customer base.

The markets in which we participate are highly competitive, with several large established competitors, and our failure to compete successfully would make it difficult for us to add and retain customers and would reduce or impede the growth of our business.

Our market is large, highly competitive, fragmented and subject to rapidly evolving technology, shifting customer needs and frequent introductions of new products and services. We currently compete with companies that offer products that target email and data security, continuity and archiving, as well as large providers such as Google Inc. and Microsoft Corporation, which offer functions and tools as part of their core mailbox services that may be, or be perceived to be, similar to ours. Our current and potential future competitors include: Barracuda Networks, Inc., Google, Microsoft Exchange Online Protection, Proofpoint, Inc., Symantec Corporation, Agari Data, Inc. and Cisco Systems Inc., in security; Dell EMC, Microsoft Office® 365®, Veritas Technologies LLC and Barracuda in archiving; and KnowBe4, Inc., Cofense Inc., and Wombat Security, a division of Proofpoint, in security awareness training. We expect competition to increase in the future from both existing competitors and new companies that may enter our markets. Additionally, some potential customers, particularly large enterprises, may elect to develop their own internal products. If two or more of our competitors were to merge or partner with one another, the change in the competitive landscape could reduce our ability to compete effectively. Our continued success and growth depends on our ability to out-perform our competitors at the individual service level as well as increasing demand for a unified service infrastructure. We cannot guarantee that we will out-perform our competitors at the product level or that the demand for a unified service technology will increase.

Some of our current competitors have, and our future competitors may have, certain competitive advantages such as greater name recognition, longer operating history, larger market share, larger existing user base and greater financial, technical and other resources. Some competitors may be able to devote greater resources to the development, promotion and sale of their products and services than we can to ours, which could allow them to respond more quickly than we can to new technologies and changes in customer needs. We cannot assure you that our competitors will not offer or develop products or services that are superior to ours or achieve greater market acceptance.

Data security and integrity are critically important to our business, and breaches of our information and technology networks and unauthorized access to a customer’s data could harm our business and operating results.

We have experienced, and will continue to experience, cyberattacks and other malicious internet-based activity, which continue to increase in sophistication, frequency and magnitude. Because our services involve the storage of large amounts of our customers’ sensitive and proprietary information, solutions to protect that information from cyberattacks and other threats, data security and integrity are critically important to our business. Despite all of our efforts to protect this information, we cannot provide assurance that systems that access our services and databases will not be compromised or disrupted, whether as a result of criminal conduct, distributed denial of service, or DDoS, attacks, such as the one we experienced in September 2015, or other advanced persistent attacks by malicious actors, including hackers, state-backed hackers and cybercriminals, breaches due to employee error or malfeasance, or other disruptions during the process of upgrading or replacing computer software or hardware, power outages, computer viruses, telecommunication or utility failures or natural disasters or other catastrophic events. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. Though it is difficult to determine what harm may directly result from any specific interruption or breach, unauthorized access to or disclosure of confidential information, disruption, including DDoS attacks, or the perception that the confidential information of our customers is not secure, any of these events could result in a material loss of business, substantial legal liability or significant harm to our reputation. Further, any mandatory regulatory disclosures regarding a security breach, unauthorized access to or disclosure of confidential information often lead to widespread negative publicity, which may cause our customers to lose confidence in the effectiveness of our data security measures.

We must continually monitor and develop our information technology networks and infrastructure to prevent, detect, address and mitigate the risk of unauthorized access and expend significant resources to respond to threats to security. However, despite our efforts, we may fail to identify these new and complex methods of attack, or fail to invest sufficient resources in security measures. In addition, as we increase our customer base and our brand becomes more widely known and recognized, we may become a more attractive target for malicious third parties. Any breach of our security measures as a result of third-party action, employee negligence and/or error, malfeasance, defects or otherwise that compromises the confidentiality, integrity or availability of our data or our customers’ data could result in:

Any of these events could materially adversely impact our business and results of operations.

Data privacy concerns, evolving regulations of cloud computing, cross-border data transfer restrictions and other domestic or foreign laws and regulations may limit the use and adoption of, or require modification of, our products and services, which could limit our ability to attract new customers or support existing customers thus reducing our revenues, harming our operating results and adversely affecting our business.

Laws and regulations related to the provision of services on the Internet are increasing, as federal, state and foreign governments continue to adopt new laws and regulations addressing data privacy and the collection, processing, storage and use of personal information. For example, in the United States, these include laws and regulations promulgated under the authority of the Federal Trade Commission, the Electronic Communications Privacy Act, the Computer Fraud and Abuse Act, the Health Insurance Portability and Accountability Act of 1996, or HIPAA, the Graham-Leach-Bliley Act of 1999, or Gramm-Leach-Bliley, and state breach notification and data privacy laws, as well as regulator enforcement positions and expectations reflected in federal and state regulatory actions, settlements, consent decrees and guidance documents. Internationally, virtually every jurisdiction in which we operate has established its own data security and privacy legal frameworks with which we, or our customers, must comply, including the European Union Data Protection Directive 95/46/EC, or the Directive, established in the European Union, or EU, and local EU Member State legislation implementing the Directive, such as the Data Protection Act in the United Kingdom. Most recently, the EU adopted the EU General Data Protection Regulation, or GDPR, which became effective on May 25, 2018 and replaced the Directive. The GDPR applies to any company established in the European Union as well as to those outside the European Union if they collect and use personal data in connection with the offering of goods or services to individuals in the European Union or the monitoring of their behavior. The GDPR enhances data protection obligations for processors and controllers of personal data, including, for example, expanded disclosures about how personal information is to be used, limitations on retention of information, mandatory data breach notification requirements and onerous new obligations on services providers. Under the GDPR, fines of up to 20,000,000 Euros or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher, may be imposed. Given the breadth and depth of changes in data protection obligations, complying with its requirements has caused us to expend significant resources and such expenditures are likely to continue into the near future as we respond to new interpretations and enforcement actions that may follow the effective date of the regulation and as we continue to negotiate data processing agreements with our customers and business partners.

To facilitate and legitimize the transfer of both customer and personnel data from the European Union to the United States, in the past we have relied on the EU-U.S. Safe Harbor Framework, which required U.S.-based companies to provide assurance that they were adhering to relevant European standards for data protection. On October 6, 2015, the Court of Justice of the European Union invalidated the EU-U.S. Safe Harbor Framework. On February 2, 2016, the U.S. and European Union announced agreement on a new framework for transatlantic data flows entitled the EU-U.S. Privacy Shield and we self-certified under the EU-US Privacy Shield framework in March 2018. However, the Privacy Shield continues to be subject to legal challenges and, as a result, there is some uncertainty regarding its future validity and our ability to rely on it for European to US data transfers. If the Privacy Shield is ultimately invalidated, we will be required to identify and implement alternative solutions to ensure that we are in compliance with European data transfer requirements. If we fail to comply fully with European privacy laws, European Union data protection authorities might impose upon us a number of different sanctions, including fines and restrictions on transfers.

Privacy and data protections laws and regulations are subject to new and differing interpretations and there may be significant inconsistency in laws and regulations among the jurisdictions in which we operate or offer our SaaS solutions. Legal and other regulatory requirements could restrict our ability to store and process data as part of our SaaS solutions, or, in some cases, impact our ability to offer our SaaS products in certain jurisdictions. Such laws may also impact our customers' ability to deploy certain of our solutions globally, to the extent they utilize our products for storing personal information that they store and process. In addition, in many cases these privacy laws apply not only to transfers of information to third parties, but also within an enterprise, including our company or our customers. Additionally, if third parties that we work with, violate applicable laws or our policies, such violations may also put our customers’ information at risk and could in turn have an adverse effect on our business. The costs of compliance with, and other burdens imposed by, data privacy laws, regulations and standards may require resources to create new products or modify existing products, could lead to us being subject to significant fines, penalties or liabilities for noncompliance, and may slow the pace at which we close sales transactions, any of which could harm our business.

If we are unable to effectively increase sales of our services to large enterprises while mitigating the risks associated with serving such customers, our business, financial position and results of operations may suffer.

As we seek to increase our sales to large enterprise customers, we may face longer sales cycles, more complex customer requirements, unfavorable contractual terms, substantial upfront sales costs and less predictability in completing some of our sales than we do with smaller customers. In addition, our ability to successfully sell our services to large enterprises is dependent on us attracting and retaining sales personnel with experience in selling to large organizations. Also, because security breaches of larger, more high-profile enterprises are likely to be heavily publicized, there is increased reputational risk associated with serving such customers. If we are unable to increase sales of our services to large enterprise customers while mitigating the risks associated with serving such customers, our business, financial position and results of operations may suffer.

If we are unable to maintain successful relationships with our channel partners, our ability to acquire new customers could be adversely affected.

In order to grow our business, we anticipate that we will continue to depend on our relationships with our channel partners who we rely on, in addition to our direct sales force, to sell and support our services. In our fiscal period ended September 30, 2018, while no individual channel partner accounted for 10% or more of our sales, in the aggregate, our channel partners accounted for 71% of our sales. We expect that sales to channel partners will continue to account for a substantial portion of our revenue for the foreseeable future. We utilize channel partners to efficiently increase the scale of our marketing and sales efforts, increasing our market penetration to customers which we otherwise might not reach on our own. Our ability to achieve revenue growth in the future will depend, in part, on our success in maintaining successful relationships with our channel partners.

Our agreements with our channel partners are generally non-exclusive, meaning our channel partners may offer customers competitive services from different companies. If our channel partners do not effectively market and sell our services, choose to use greater efforts to market and sell their own products or services or those of others, or fail to meet the needs of our customers, our ability to grow our business, sell our services and maintain our reputation may be adversely affected. Our agreements with our channel partners generally allow them to terminate their agreements for any reason upon 90 days’ notice. The loss of key channel partners, our possible inability to replace them, or the failure to recruit additional channel partners could materially adversely affect our results of operations. If we are unable to maintain our relationships with these channel partners, our business, results of operations, financial condition or cash flows could be adversely affected.

We provide service level commitments under our subscription agreements and service disruptions could obligate us to provide refunds and we could face subscription terminations, which could adversely affect our revenue.

Our subscription agreements with customers provide certain service level commitments. If we are unable to meet the stated service level commitments or suffer extended periods of downtime that exceed the periods allowed under our customer agreements, we could be required to pay refunds or face subscription terminations, either of which could significantly impact our revenue.

To date, we have suffered two significant service disruptions. The first occurred in 2013 and was a result of an equipment failure. Many of our customers in the United Kingdom experienced service disruptions for several hours. We also experienced a service disruption in September 2015 as a result of an external network DDoS attack. Customers using our Secure Email Gateway service in the United States experienced downtime related to the delivery and receipt of external emails for several hours. The scope of the incident was limited to network traffic and no customer data was lost or compromised. As a result of the service disruption, we voluntarily provided service credits to affected customers in the year ended March 31, 2016, totaling approximately $0.4 million. While we have undertaken substantial remedial efforts to prevent future incidents like these, we cannot guarantee that future attacks or service disruptions will not occur. Any future attacks or service disruptions could adversely affect our reputation, our relationships with our existing customers and our ability to attract new customers, all of which would impact our future revenue and operating results.

We have acquired, and may acquire in the future, other businesses, products or technologies, which could require significant management attention, disrupt our business, dilute shareholder value and adversely affect our results of operations.

As part of our business growth strategy and in order to remain competitive, we may acquire, or make investments in, complementary companies, products or technologies. For example, in fiscal 2017, we acquired substantially all of the business of iSheriff, Inc., a cloud security provider, and in fiscal 2018, we acquired machine learning-based malware detection technology. In July 2018, we acquired Ataata, a security awareness training provider, and Solebit, an Israeli-based developer of security software. Notwithstanding these recent acquisitions, our acquisition experience to date remains limited, and as a result, our ability as an organization to acquire and integrate other companies, products or technologies, particularly when the acquired entities are located in geographies where we have not previously done business, such as Israel, in a successful manner is unproven. We may not be able to find suitable acquisition targets, and we may not be able to complete such acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by our customers, analysts and investors. In addition, if we are unsuccessful at integrating such acquisitions or the technologies associated with such acquisitions, our revenue and results of operations could be adversely affected. In addition, while we will make significant efforts to address any information technology security issues with respect to any acquisitions, we may still inherit such risks when we integrate the acquired products, technology and systems. Any integration process may require significant time and resources, and we may not be able to manage the process successfully. We may not successfully evaluate or utilize the acquired technology or personnel, or accurately forecast the financial impact of an acquired business, including accounting charges. We may have to pay cash, incur debt, or issue equity securities to pay for any such acquisitions, each of which could adversely affect our financial condition or the value of our ordinary shares. The sale of equity or issuance of debt to finance any such acquisitions could result in dilution to our shareholders. The incurrence of indebtedness would result in increased fixed obligations and could also include covenants or other restrictions that would impede our ability to manage our operations. See The terms of our Credit Facility require us to comply with certain financial covenants and impose restrictions on our business and operations, which creates default risks and reduces our flexibility below.

If we are not able to provide successful updates, enhancements and features to our technology to, among other things, keep up with emerging cyber-threats and customer needs, our business could be adversely affected.

Our industry is marked by rapid technological developments and demand for new and enhanced services and features to meet the evolving IT needs of organizations. In particular, cyber-threats are becoming increasingly sophisticated and responsive to the new security measures designed to thwart them. If we fail to identify and respond to new and increasingly complex methods of attack and update our products to detect or prevent such threats, our business and reputation will suffer. The success of any new enhancements, features or services that we introduce depends on several factors, including the timely completion, introduction and market acceptance of such enhancements, features or services. We may not be successful in either developing these modifications and enhancements or in bringing them to market in a timely fashion. Furthermore, modifications to existing technologies will increase our research and development expenses. If we are unable to successfully enhance our existing services to meet customer requirements, increase adoption and usage of our services, or develop new services, enhancements and features, our business and operating results will be harmed.

Because we recognize revenue from subscriptions for our services over the term of the agreement, downturns or upturns in new business may not be immediately reflected in our operating results and may be difficult to discern.

We generally recognize subscription revenue from customers ratably on a straight-line basis over the terms of their subscription agreements, which are typically one year in duration. As a result, most of the revenue we report in each quarter is derived from the recognition of deferred revenue relating to subscription agreements entered into during the previous fiscal year or quarter. Consequently, a decline in new or renewed subscriptions with yearly terms in any one quarter may have a small impact on our operating revenue results for that quarter. However, such decline will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in sales and market acceptance of our services, and potential changes in our pricing policies, rate of expansion or retention rate may not be fully reflected in our operating results until future periods. Shifts in the mix of annual versus monthly subscription billings may also make it difficult to assess our business. We may also be unable to reduce our cost structure in line with a significant deterioration in sales. In addition, a significant majority of our costs are expensed as incurred, while revenue is recognized over the life of the agreement with our customer. As a result, increased growth in the number of our customers could continue to result in our recognition of more costs than revenue in the earlier periods of the terms of our agreements. Our subscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as revenue from new customers is recognized over the applicable subscription term.

We have incurred losses in the past, and we may not be able to achieve or sustain profitability for the foreseeable future.

We have incurred losses in each period since our inception in 2003 up through our fiscal year ended March 31, 2018, with the exception of our fiscal year ended March 31, 2015 in which we generated net income of $0.3 million. In our six month periods ended September 30, 2018 and 2017, we incurred a net loss of $5.5 million and $3.2 million, respectively. As of September 30, 2018, we had an accumulated deficit of $82.2 million. We have been growing rapidly, and, as we do so, we incur significant sales and marketing, support and other related expenses. Our ability to achieve and sustain profitability will depend in significant part on our obtaining new customers, expanding our existing customer relationships and ensuring that our expenses, including our sales and marketing expenses and the cost of supporting new customers, does not exceed our revenue. We also expect to make significant expenditures and investments in research and development to expand and improve our services and technical infrastructure. In addition, as a public company, we expect to continue to incur significant legal, accounting and other expenses that we did not incur prior to our initial public offering in November 2015. These increased expenditures may make it harder for us to achieve and maintain profitability and we cannot predict when we will achieve sustained profitability, if at all. We also may incur losses in the future for a number of other unforeseen reasons. Accordingly, we may not be able to maintain profitability, once achieved, and we may incur losses in the foreseeable future.

We are subject to a number of risks associated with global sales and operations.

We operate a global business with offices located in the United States, the United Kingdom, South Africa, Australia and Germany as well as several other locations. In the fiscal period ended September 30, 2018, we generated 49% of our revenue from the United States, 31% from the United Kingdom, 14% from South Africa and 6% from the rest of the world. As a result, our sales and operations are subject to a number of risks and additional costs, including the following:

For example, in June 2016, the United Kingdom held a referendum in which a majority of voters approved an exit from the European Union, or Brexit, and in March 2017, the United Kingdom formally notified the European Union of its intention to withdraw from the European Union. A two-year period has now commenced during which the United Kingdom and the European Union will negotiate the future terms of the United Kingdom's relationship with the European Union, including, among other things, the terms of trade between the United Kingdom and the European Union. Brexit may affect our results of operations in a number of ways, including increasing currency exchange risk, generating instability in the global financial markets or negatively impacting the economies of the United Kingdom or Europe. In addition, because of our significant presence in the United Kingdom, it is possible that Brexit may require us to restructure some or all of our operations. The long-term effects of Brexit will depend in part on any agreements the United Kingdom makes to retain access to markets in the European Union following the withdrawal from the European Union. In addition, we expect that Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the United Kingdom determines which European Union laws to replicate or replace.

The factors discussed above and other factors could harm our ability to generate future global revenue and, consequently, materially impact our business, results of operations and financial condition.

Our functional currency and that of our subsidiaries is the local currency of each entity and our reporting currency is the U.S. dollar. In our six-month period ended September 30, 2018, 51% of our revenue was denominated in U.S. dollars, 29% in British pounds, 14% in South African rand and 6% in other currencies. Given that our functional currency and that of our subsidiaries is the local currency of each entity, but our reporting currency is the U.S. dollar, fluctuations in currency exchange rates between the U.S. dollar, the British pound, the South African rand and the Australian dollar could materially and adversely affect our business. There may be instances in which costs and revenue will not be matched with respect to currency denomination. We estimate that a 10% increase or decrease in the value of the British pound against the U.S. dollar would have increased or decreased our loss from operations by approximately $1.0 million in our fiscal period ended September 30, 2018 and that a 10% increase or decrease in the value of the South African rand against the U.S. dollar would have decreased or increased our loss from operations by approximately $1.4 million in our six month period ended September 30, 2018. To date, we have not entered into any currency hedging contracts. As a result, to the extent we continue our expansion on a global basis, we expect that increasing portions of our revenue, cost of revenue, assets and liabilities will be subject to fluctuations in currency valuations. We may experience economic loss and a negative impact on earnings or net assets solely as a result of currency exchange rate fluctuations.

Brexit may continue to have a significant impact on currency exchange rates and the global and European economy generally. The outcome of the referendum caused volatility in global stock markets and foreign currency exchange rate fluctuations, including the strengthening of the U.S. dollar against the British pound and the euro, which may continue or worsen as the outcome of the negotiations between the United Kingdom and the European Union becomes clear.

We are dependent on the continued services and performance of our two founders, the loss of either of whom could adversely affect our business.

Our future performance depends upon contributions from our senior management team and, in particular, our two founders, Peter Bauer, our Chairman and Chief Executive Officer, and Neil Murray, our Chief Technology Officer. If our senior management team, including any new hires that we may make, fails to work together effectively and to execute on our plans and strategies on a timely basis, our business could be harmed. The loss of one or more of our executive officers or key employees could have an adverse effect on our business. The loss of services of either Mr. Bauer or Mr. Murray could significantly delay or prevent the achievement of our development and strategic objectives.

We depend on highly skilled personnel to grow and operate our business, and if we are unable to hire, retain and motivate qualified personnel, we may not be able to grow effectively.

Our success depends largely upon our continued ability to identify, hire, develop, motivate and retain highly skilled personnel, including senior management, engineers, software developers, sales representatives and customer support representatives. Our growth strategy also depends, in part, on our ability to continue to attract and retain highly skilled personnel. Identifying, recruiting, training and integrating qualified individuals requires significant time, expense and attention of management. Competition for these personnel is intense, especially for engineers experienced in designing and developing software and software as a service, or SaaS, applications, and for experienced sales professionals. We have, from time to time experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may assert that these employees or we have breached their legal obligations, resulting in a diversion of our time and resources. In addition, prospective and existing employees often consider the value of the equity awards they receive in connection with their employment. If the actual or perceived value of our equity awards declines, or experiences significant volatility, it may adversely affect our ability to recruit and retain key employees. If we are not able to effectively recruit and retain qualified employees, our ability to achieve our strategic objectives will be adversely impacted, and our business will be harmed.

Any serious disruptions in our services caused by defects in our software or otherwise may cause us to lose revenue and market acceptance.

Our customers use our services for the most critical aspects of their business, and any disruptions to our services or other performance problems with our services, however caused, could hurt our brand and reputation and may damage our customers’ businesses. We provide regular updates, which may contain undetected errors when first introduced or released. In the past, we have discovered software errors, failures, vulnerabilities and bugs in our services after they have been released and new errors in our existing services may be detected in the future. Real or perceived errors, failures, system delays, interruptions, disruptions or bugs could result in negative publicity, loss of or delay in market acceptance of our services, loss of competitive position, delay of payment to us, lower renewal rates, or claims by customers for losses sustained by them. In such an event, we may be required, or may choose, for customer relations or other reasons, to expend additional resources in order to mitigate or correct the problem. We seek to cap the liability to which we are exposed in the event of losses or harm to our customers, but we cannot be certain that we will obtain these caps or that these caps, if obtained, will be enforced in all instances. We carry insurance; however, the amount of such insurance may be insufficient to compensate us for any losses that may result from claims arising from defects or disruptions in our services. As a result, we could lose future sales and our reputation and our brand could be harmed.

If the prices we charge for our services are unacceptable to our customers, our operating results will be harmed.

As the market for our services matures, or as new or existing competitors introduce new products or services that compete with ours, we may experience pricing pressure and be unable to renew our agreements with existing customers or attract new customers at prices that are consistent with our pricing model and operating budget. If this were to occur, it is possible that we would have to change our pricing model or reduce our prices, which could harm our revenue, gross margin and operating results. Pricing decisions may also impact the mix of adoption among our subscription plans and negatively impact our overall revenue. Moreover, large enterprises, which may account for a larger portion of our business in the future, may demand substantial price concessions. If we are, for any reason, required to reduce our prices, our revenue, gross margin, profitability, financial position and cash flow may be adversely affected.

Our research and development efforts may not produce new services or enhancements to existing services that result in significant revenue or other benefits in the near future, if at all.

We invested 17%, 13% and 12% of our revenue in research and development in the six month periods ended September 30, 2018, 2017 and 2016, respectively. We expect to continue to dedicate significant financial and other resources to our research and development efforts in order to maintain our competitive position. However, investing in research and development personnel, developing new services and enhancing existing services is expensive and time-consuming, and there is no assurance that such activities will result in significant new marketable services, enhancements to existing services, design improvements, cost savings, revenue or other expected benefits. If we spend significant time and effort on research and development and are unable to generate an adequate return on our investment, our business and results of operations may be materially and adversely affected.

We employ third-party licensed software for use in or with our services, and the inability to maintain these licenses or errors in the software we license could result in increased costs, or reduced service levels, which would adversely affect our business.

Our services incorporate and rely on certain third-party software obtained under licenses from other companies. We anticipate that we will continue to rely on such third-party software and development tools in the future. Although we believe that there are commercially reasonable alternatives to the third-party software we currently license, this may not always be the case, or it may be difficult or costly to replace. In addition, integration of the software used in our services with new third-party software may require significant work and require substantial investment of our time and resources and delays in the release of our services until equivalent technology is either developed by us, or, if available, is identified, obtained and integrated, which could harm our business. A licensor may have difficulties keeping up with technological changes or may stop supporting the software or other intellectual property that it licensed to us. Also, to the extent that our services depend upon the successful operation of third-party software in conjunction with our software, any undetected errors or defects in this third-party software could prevent the deployment or impair the functionality of our services, delay new services introductions, result in a failure of our services, and injure our reputation. Our use of additional or alternative third-party software would require us to enter into additional license agreements with third parties on terms that may not be favorable to us.

If the market for SaaS business software applications develops more slowly than we expect or declines, our business would be adversely affected.

The expansion of the SaaS business applications market depends on a number of factors, including the cost, performance and perceived value associated with SaaS, as well as the ability of SaaS providers to address data security and privacy concerns. Additionally, government agencies have adopted, or may adopt, laws and regulations regarding the collection and use of personal information obtained from consumers and other individuals, or seek to access information on our platform, either of which may reduce the overall demand for our platform. If we or other SaaS providers experience data security incidents, loss of customer data, disruptions in delivery, or other problems, the market for SaaS business applications, including our services, may be negatively affected.

Natural disasters, power loss, telecommunications failures and similar events could cause interruptions or performance problems associated with our information and technology infrastructure that could impair the delivery of our services and harm our business.

We currently store our customers’ information within twelve third-party data center hosting facilities located in twelve locations around the world. As part of our current disaster recovery arrangements, our production environment and all of our customers’ data is currently replicated in near real-time in a facility located in a different location. We cannot provide assurance that the measures we have taken to eliminate single points of failure will be effective to prevent or minimize interruptions to our operations. Our facilities are vulnerable to interruption or damage from a number of sources, many of which are beyond our control, including floods, fires, power loss, telecommunications failures and similar events. They may also be subject to break-ins, sabotage, intentional acts of vandalism and similar misconduct. Any damage to, or failure of, our systems generally could result in interruptions in our service. Interruptions in our service may reduce our revenue, cause customers to terminate their subscriptions and adversely affect our renewal rate and our ability to attract new customers. Our business and reputation will also be harmed if our existing and potential customers believe our service is unreliable. The occurrence of a natural disaster, an act of terrorism, a decision to close the facilities without adequate notice or other unanticipated problems at these facilities could result in lengthy interruptions in our service. Even with the disaster recovery arrangements, our service could be interrupted. As we continue to add data centers and add capacity in our existing data centers, we may move or transfer our data and our customers’ data. Any unsuccessful data transfers may impair the delivery of our service. Further, as we continue to grow and scale our business to meet the needs of our customers, additional burdens may be placed on our hosting facilities.

We are a multinational organization faced with increasingly complex tax issues in many jurisdictions, and we could be obligated to pay additional taxes in various jurisdictions.

As a multinational organization, we may be subject to taxation in several jurisdictions around the world with increasingly complex tax laws, the application of which can be uncertain. The amount of taxes we pay in these jurisdictions could increase substantially as a result of changes in the applicable tax principles, including increased tax rates, new tax laws or revised interpretations of existing tax laws and precedents, which could have a material adverse effect on our liquidity and results of operations. In addition, the authorities in these jurisdictions could review our tax returns and impose additional tax, interest and penalties, and the authorities could claim that various withholding requirements apply to us or our subsidiaries or assert that benefits of tax treaties are not available to us or our subsidiaries. Furthermore, one or more jurisdictions in which we do not believe we are currently subject to tax payment, withholding, or filing requirements, could assert that we are subject to such requirements. Any of these claims or assertions could have a material impact on us and the results of our operations.

We are subject to governmental export controls and funds dealings restrictions that could impair our ability to compete in certain international markets and subject us to liability if we are not in full compliance with applicable laws.

Our software and services may be subject to export controls and we may also be subject to restrictions or prohibitions on transactions with, or on dealing in funds transfers to/from, certain embargoed jurisdictions and sanctioned persons and entities, pursuant to the U.K. Export Control Organisation’s restrictions, the U.K. Treasury’s restrictions, the EU Council Regulations, the United States Department of Commerce’s Export Administration Regulations, the economic and trade sanctions regulations administered by the United States Treasury Department’s Office of Foreign Assets Controls and United States Department of State, and similar laws that may apply in other jurisdictions in which we operate or sell or distribute our services. Export control and economic sanctions laws include prohibitions on the sale or supply of certain products and services to certain embargoed or sanctioned countries, regions, governments, persons and entities, as well as restrictions or prohibitions on dealing in funds to/from those countries, regions, governments, persons and entities. In addition, various countries regulate the import of certain encryption items and technology through import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our services or could limit our customers’ ability to implement our services in those countries.

The exportation, re-exportation, and importation of our software and services, including by our channel partners, must comply with applicable laws or else we may be adversely affected, through reputational harm, government investigations, penalties, and/or a denial or curtailment of our ability to export our services. Although we take precautions to prevent our services from being provided in violation of such laws, our services may have been in the past, and could in the future be, provided in violation of such laws.

If we are found to be in violation of U.S. sanctions or export control laws, it could result in substantial fines and penalties for us and for the individuals working for us, including civil penalties of up to $250,000 or twice the value of the transaction, whichever is greater, per violation, and in the event of conviction for a criminal violation, fines of up to $1 million and possible incarceration for responsible employees and managers for willful and knowing violations. Under the terms of applicable regulations, each instance in which a company provides goods or services may be considered a separate violation. If we are found to be in violation of U.K. sanctions or export controls, it could also result in unlimited fines for us and responsible employees and managers, as well as imprisonment of up to two years for responsible employees and managers.

Changes in our software or services, or changes in export, sanctions or import laws, may delay the introduction and sale of our services in international markets, prevent our customers with international operations from deploying our software or services or, in some cases, prevent the export or import of our software or services to certain countries, regions, governments, persons or entities altogether, which could adversely affect our business, financial condition and operating results.

Our quarterly results may fluctuate for a variety of reasons and may not fully reflect the underlying performance of our business.

Our quarterly operating results, including the levels of our revenue, gross margin, profitability, cash flow and deferred revenue, may vary significantly in the future, and period-to-period comparisons of our operating results may not be meaningful. Accordingly, the results of any one quarter should not be relied upon as an indication of future performance. Our quarterly financial results may fluctuate as a result of a variety of factors, many of which are outside of our control and, as a result, may not fully reflect the underlying performance of our business. Fluctuations in quarterly results may negatively impact the value of our ordinary shares. Factors that may cause fluctuations in our quarterly financial results include, but are not limited to:

The terms of our Credit Facility require us to comply with certain financial covenants and impose restrictions on our business and operations, which creates default risks and reduces our flexibility.

In July 2018, we, together with certain of our subsidiaries as guarantors, entered into a Credit Agreement with certain financial institutions, as lenders, and the Administrative Agent. The Credit Agreement provides us with a $100,000,000 senior secured term loan, and a $50,000,000 senior secured revolving credit facility. The Credit Agreement requires compliance with significant financial and non-financial covenants, including affirmative covenants relating to the provision of annual and quarterly financial statements and compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters and negative covenants, including, among others, restrictions on the incurrence of certain indebtedness, granting of liens, making investments and acquisitions, merger and consolidations, paying dividends, entering into affiliate transactions and asset sales. The Credit Agreement also provides for a number of events of default, including, among others, payment, bankruptcy, covenant, representation and warranty, change of control and judgment defaults.

As a result of the negative covenants, we may be restricted from engaging in business or operating activities that may otherwise improve our business or from financing future operations or capital needs. Failure to comply with the covenants, including the financial covenants, if not cured or waived, could result in an event of default that could trigger acceleration of our indebtedness, which would require us to repay all amounts owing under our Credit Facility and could have a material adverse impact on our business. We cannot be certain that our future operating results will be sufficient to ensure compliance with the financial covenants in our Credit Agreement or to remedy any defaults. In addition, in the event of any event of default and related acceleration, we may not have or be able to obtain sufficient funds to make any accelerated payments.

If we need to raise additional capital to expand our operations and invest in new technologies in the future and cannot raise it on acceptable terms or at all, our ability to compete successfully may be harmed.

We believe that our existing cash and cash equivalents together with available capacity under our Credit Facility will be sufficient to meet our anticipated cash requirements for at least the next twelve months. However, unforeseen circumstances may arise which may mean that we may need to raise additional funds, and we may not be able to obtain additional debt or equity financing on favorable terms, if at all, or because of restrictions in our Credit Facility. If we raise additional equity financing, our security holders may experience significant dilution of their ownership interests and the value of our ordinary shares could decline. If we engage in additional debt financing, we may be required to accept terms that are more restrictive than the terms currently applicable to us under the Credit Facility. If we need additional capital and cannot raise it on acceptable terms, if at all, we may not be able to, among other things:

Our inability to do any of the foregoing could reduce our ability to compete successfully and harm our results of operations.

Any failure to protect our intellectual property rights could impair our ability to protect our proprietary technology and our brand.

Our success and ability to compete depend in part on our intellectual property. We primarily rely on copyright, trade secret and trademark laws, trade secret protection and confidentiality or license agreements with our employees, customers, partners and others to protect our intellectual property rights. However, the steps we take to protect our intellectual property rights may be inadequate. As of September 30, 2018, we have 14 patents issued and 18 patent applications pending in the United States. We also have 5 patents issued and 2 patent applications pending for examination in non-U.S. jurisdictions. We may not be able to obtain any further patents, and our pending applications may not result in the issuance of patents. We have issued patents and pending patent applications outside the United States, and we may have to expend significant resources to obtain additional patents as we expand our international operations due to the cost of monitoring and protecting our rights across multiple jurisdictions.

In order to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Failure to adequately enforce our intellectual property rights could also result in the impairment or loss of those rights. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. Patent, copyright, trademark and trade secret laws offer us only limited protection and the laws of many of the countries in which we sell our services do not protect proprietary rights to the same extent as the United States and Europe. Accordingly, defense of our trademarks and proprietary technology may become an increasingly important issue as we continue to expand our operations and solution development into countries that provide a lower level of intellectual property protection than the United States or Europe. Policing unauthorized use of our intellectual property and technology is difficult and the steps we take may not prevent misappropriation of the intellectual property or technology on which we rely. For example, in the event of inadvertent or malicious disclosure of our proprietary technology, trade secret laws may no longer afford protection to our intellectual property rights in the areas not otherwise covered by patents or copyrights. Accordingly, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Our failure to secure, protect and enforce our intellectual property rights could materially adversely affect our brand and our business.

We may elect to initiate litigation in the future to enforce or protect our proprietary rights or to determine the validity and scope of the rights of others. That litigation may not be ultimately successful and could result in substantial costs to us, the reduction or loss in intellectual property protection for our technology, the diversion of our management’s attention and harm to our reputation, any of which could materially and adversely affect our business and results of operations.

We may be sued by third parties for alleged infringement of their proprietary rights.

There is considerable patent and other intellectual property development activity in our industry. Our success depends, in part, on our not infringing upon the intellectual property rights of others. Our competitors, as well as a number of other entities, including non-practicing entities, which are entities that have no operating business but exist purely as collectors of patents, and individuals, may own or claim to own intellectual property relating to our industry.

From time to time, certain third parties have claimed that we are infringing upon their intellectual property rights. In the future, we may be found to be infringing upon such rights. We closely monitor all such claims and none of the claims by the third parties have resulted in litigation, but legal actions by such parties are still possible. In addition, we cannot assure you that actions by other third parties alleging infringement by us of third-party patents or other intellectual property will not be asserted or prosecuted against us. In the future, others may claim that our services and underlying technology infringe or violate their intellectual property rights. We may also be unaware of the intellectual property rights that others may claim cover some or all of our technology or services. Any claims or litigation could cause us to incur significant expenses and, if successfully asserted against us, could require that we pay substantial damages or ongoing royalty payments, prevent us from offering our services, or require that we comply with other unfavorable terms. Under all of our sales contracts, we are obligated to indemnify our customers and channel partners against third-party infringement claims, and we may also be obligated to pay substantial settlement costs, including royalty payments, in connection with any such claim or litigation and to obtain licenses, modify services or refund fees, any of which could be costly. Even if we were to prevail in such a dispute, any litigation regarding intellectual property could be costly and time-consuming and divert the attention of our management and key personnel from our business operations.

Confidentiality arrangements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information.

We have devoted substantial resources to the development of our technology, business operations and business plans. In order to protect our trade secrets and proprietary information, we rely in significant part on confidentiality arrangements with our employees, licensees, independent contractors, advisers, channel partners, resellers and customers. These arrangements may not be effective to prevent disclosure of confidential information, including trade secrets, and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, if others independently discover trade secrets and proprietary information, we would not be able to assert trade secret rights against such parties. Effective trade secret protection may not be available in every country in which our services are available or where we have employees or independent contractors. The loss of trade secret protection could make it easier for third parties to compete with our solutions by copying functionality. In addition, any changes in, or unexpected interpretations of, the trade secret and employment laws in any country in which we operate may compromise our ability to enforce our trade secret and intellectual property rights. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

We may be subject to damages resulting from claims that our employees or contractors have wrongfully used or disclosed alleged trade secrets of their former employers or other parties.

We could in the future be subject to claims that employees or contractors, or we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of our competitors or other parties. Litigation may be necessary to defend against these claims. If we fail in defending against such claims, a court could order us to pay substantial damages and prohibit us from using technologies or features that are essential to our solutions, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of these parties. In addition, we may lose valuable intellectual property rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to develop, market and support potential solutions or enhancements, which could severely harm our business. Even if we are successful in defending against these claims, such litigation could result in substantial costs and be a distraction to management.

The use of open source software in our offerings may expose us to additional risks and harm our intellectual property.

Open source software is typically freely accessible, usable and modifiable. Certain open source software licenses require a user who intends to distribute the open source software as a component of the user’s software to disclose publicly part or all of the source code to the user’s software. In addition, certain open source software licenses require the user of such software to make any derivative works of the open source code available to others on unfavorable terms or at no cost. This can subject previously proprietary software to open source license terms.

We monitor and control our use of open source software in an effort to avoid unanticipated conditions or restrictions on our ability to successfully commercialize our products and solutions and believe that our compliance with the obligations under the various applicable licenses has mitigated the risks that we have triggered any such conditions or restrictions. However, such use may have inadvertently occurred in the development and offering of our products and solutions. Additionally, if a third-party software provider has incorporated certain types of open source software into software that we have licensed from such third-party, we could be subject to the obligations and requirements of the applicable open source software licenses. This could harm our intellectual property position and have a material adverse effect on our business, results of operations and financial condition.

The terms of many open source software licenses have not been interpreted by U.S. or foreign courts, and there is a risk that those licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to successfully commercialize our products and solutions. For example, certain open source software licenses may be interpreted to require that we offer our products or solutions that use the open source software for no cost; that we make available the source code for modifications or derivative works we create based upon, incorporating or using the open source software (or that we grant third parties the right to decompile, disassemble, reverse engineer, or otherwise derive such source code); that we license such modifications or derivative works under the terms of the particular open source license; or that otherwise impose limitations, restrictions or conditions on our ability to use, license, host, or distribute our products and solutions in a manner that limits our ability to successfully commercialize our products.

We could, therefore, be subject to claims alleging that we have not complied with the restrictions or limitations of the applicable open source software license terms or that our use of open source software infringes the intellectual property rights of a third-party. In that event, we could incur significant legal expenses, be subject to significant damages, be enjoined from further sale and distribution of our products or solutions that use the open source software, be required to pay a license fee, be forced to reengineer our products and solutions, or be required to comply with the foregoing conditions of the open source software licenses (including the release of the source code to our proprietary software), any of which could adversely affect our business. Even if these claims do not result in litigation or are resolved in our favor or without significant cash settlements, the time and resources necessary to resolve them could harm our business, results of operations, financial condition and reputation.

Additionally, the use of open source software can lead to greater risks than the use of third-party commercial software, as open source software does not come with warranties or other contractual protections regarding indemnification, infringement claims or the quality of the code.

The market price of our ordinary shares may decline. In addition, the market price of our ordinary shares could be highly volatile and may fluctuate substantially as a result of many factors, many of which we cannot control, including:

In addition, the stock markets have experienced extreme price and volume fluctuations. Broad market and industry factors may materially harm the market price of our ordinary shares, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted against that company. If we were involved in any similar litigation we could incur substantial costs and our management’s attention and resources could be diverted.

If securities or industry analysts cease to publish research or publish inaccurate or unfavorable research about our business, our share price and trading volume could decline.

The trading market for our ordinary shares depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who covers us downgrades our shares or publishes inaccurate or unfavorable research about our business, our share price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our shares could decrease, which could cause our share price and trading volume to decline.

We do not expect to pay dividends and investors should not buy our ordinary shares expecting to receive dividends.

We do not anticipate that we will declare or pay any dividends in the foreseeable future, and our ability to do so may be constrained by restrictions in future debt arrangements, if any, and by Jersey law. Consequently, investors will only realize an economic gain on their investment in our ordinary shares if the price appreciates. Investors should not purchase our ordinary shares expecting to receive cash dividends. Since we do not pay dividends, and if we are not successful in sustaining an orderly trading market for our shares, investors may not have any manner to liquidate or receive any payment on their investment. Therefore, our failure to pay dividends may cause investors to not see any return on your investment even if we are successful in our business operations. In addition, because we do not pay dividends we may have trouble raising additional funds which could affect our ability to expand our business operations.

The market price of our ordinary shares could be negatively affected by future sales of our ordinary shares.

Sales by us or our shareholders of a substantial number of ordinary shares in the public market, or the perception that these sales might occur, could cause the market price of our ordinary shares to decline or could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity securities.

We have filed with the SEC a Registration Statement on Form F-3, commonly referred to as a “shelf registration,” that permits us to sell in a registered offering up to $50 million of our securities at our discretion. The shelf registration was declared effective by the SEC in March 2017. While we have no current plans to conduct an offering of securities under the shelf registration statement, our plans could change at any time. In addition, the shelf registration statement also covers the registration of ordinary shares held by certain of our existing shareholders. By agreement, these shareholders are entitled to demand that we register their shares under the Securities Act of 1933, as amended, or the Securities Act, for resale into the public markets and they could exercise their rights by requiring that we initiate an offering under the shelf registration statement.

In addition to our current shareholders’ registration rights and our existing shelf registration statement, as of September 30, 2018, we had outstanding options and unvested restricted share units to purchase 7,582,641 shares under our equity incentive plans and had an additional 6,387,854 shares available for future grant.

As a result of the loss of our foreign private issuer status, we are now required to comply with the Exchange Act’s domestic reporting regime, which will cause us to incur significant legal, accounting and other expenses.

As of September 30, 2017, we determined that we no longer qualify as a “foreign private issuer” as such term is defined in Rule 405 under the Securities Act, which means that we are required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers as of April 1, 2018. As of April 1, 2018, we have been required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We have been required to make changes in our corporate governance practices in accordance with various SEC and NASDAQ rules. In addition, our officers and directors are no longer exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchase and sales of our securities. As a result of such compliance, the regulatory and compliance costs to us under U.S. securities laws may be significantly higher than the cost we would incur as a foreign private issuer and therefore, we expect that the loss of foreign private issuer status will increase our legal and financial compliance costs and would make some activities highly time consuming and costly.

We must maintain proper and effective internal controls over financial reporting and any failure to maintain the adequacy of these internal controls may adversely affect investor confidence in our company and, as a result, the value of our ordinary shares.

We are required, pursuant to Section 404 of the Sarbanes-Oxley Act and the related rules adopted by the SEC, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting on an annual basis. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal controls are effective.

In addition, our independent registered public accounting firm must attest to the effectiveness of our internal control over financial reporting under Section 404. Our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. We may not be able to remediate any future material weaknesses, or to complete our evaluation, testing and any required remediation in a timely fashion. We are also required to disclose significant changes made in our internal control procedures on a quarterly basis. Our compliance with Section 404 will require that we incur substantial accounting expense and expend significant management efforts.

Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition or results of operations. If we are unable to assert that our internal control over financial reporting is effective or our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls when it is required to issue such opinion, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our ordinary shares could decline, and we could be subject to sanctions or investigations by NASDAQ, the SEC or other regulatory authorities.

Changes in U.S. tax laws could have a material adverse effect on our business, cash flow, results of operations or financial conditions.

The Tax Cuts and Jobs Act of 2017, which has been passed by the U.S. Congress and signed by the President, contains many significant changes to the U.S. federal income tax laws, the consequences of which have not yet been fully determined. Changes in corporate tax rates, the realizability of the net deferred tax assets relating to our U.S. subsidiary, and the deductibility of expenses contained in the Tax Cuts and Jobs Act or other tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges in the current or future taxable years, and could increase our future U.S. tax expense. The foregoing items could have a material adverse effect on our business, cash flow, results of operations or financial conditions.

A change in our tax residence could have a negative effect on our future profitability.

Although we are organized under the laws of the Bailiwick of Jersey, our affairs are, and are intended to continue to be, managed and controlled in the United Kingdom for tax purposes and therefore we are resident in the United Kingdom for U.K. and Jersey tax purposes. It is possible that in the future, whether as a result of a change in law or the practice of any relevant tax authority or as a result of any change in the conduct of our affairs or for any other reason, we could become, or be regarded as having become, a resident in a jurisdiction other than the United Kingdom. If we cease to be a U.K. tax resident, we may be subject to a charge to U.K. corporation tax on chargeable gains on our assets and to unexpected tax charges in other jurisdictions on our income. Similarly, if the tax residency of any of our subsidiaries were to change from their current jurisdiction for any of the reasons listed above, we may be subject to a charge to local capital gains tax on the assets.

Taxing authorities could reallocate our taxable income among our subsidiaries, which could increase our consolidated tax liability.

We conduct operations world-wide through subsidiaries in various tax jurisdictions pursuant to transfer pricing arrangements between our company and its subsidiaries. If two or more affiliated companies are located in different countries, the tax laws or regulations of each country generally will require that transfer prices be the same as those between unrelated companies dealing at arm’s length and that appropriate documentation is maintained to support the transfer pricing. While we believe that we operate in compliance with applicable transfer pricing laws and intend to continue to do so, our transfer pricing procedures are not binding on applicable tax authorities. If tax authorities in any of these countries were to successfully challenge our transfer prices as not reflecting arms’ length transactions, they could require us to adjust our transfer prices and thereby reallocate our income to reflect these revised transfer prices, which could result in a higher tax liability to us. In addition, if the country from which the income is reallocated does not agree with the reallocation, both countries could tax the same income, resulting in double taxation. If tax authorities were to allocate income to a higher tax jurisdiction, subject our income to double taxation or assess interest and penalties, it would increase our consolidated tax liability, which could adversely affect our financial condition, results of operations and cash flows. Double taxation should be mitigated in these circumstances where the affiliated parties that are subject to the transfer pricing adjustments are able to benefit from any applicable double taxation agreement.

Our ability to use our net operating loss or tax credit carry forwards may be subject to limitation.

As of September 30, 2018, we had net operating loss carryforwards in the U.K., U.S. federal and state, Australia, Germany and Israel. U.S. federal net operating losses generated through the fiscal year ending March 31, 2017 expire at various dates through 2037 while U.S. federal net operating losses generating after March 31, 2017 do not expire. The U.S. state net operating loss carryforwards expire at various dates through 2038. Net operating loss carryforwards in the U.K., Australia, Germany and Israel do not expire. As of September 30, 2018, we had a UK income tax credit carryforward that does not expire. As of September 30, 2018, we had Israel income tax credits that expire in 2024 and 2025.

Each jurisdiction in which we operate may have its own limitations on our ability to utilize net operating loss or tax credit carryforwards generated in that jurisdiction that may increase our U.K. and/or foreign income tax liability.

Under Section 382 of the U.S. Internal Revenue Code, if a corporation undergoes an ownership change, the corporation’s ability to use its pre-change net operating loss carryforwards to offset its post-change income and taxes may be limited. In general, an ownership change occurs if there is a 50 percent cumulative change in ownership of the Company over a rolling three-year period. Similar rules may apply under U.S. state tax laws. The Company believes that it has experienced an ownership change in the past and may experience ownership changes in the future resulting from future transactions in our share capital, some of which may be outside the Company’s control. The Company’s ability to utilize its net operating loss carryforwards or other tax attributes to offset U.S. federal and state taxable income in the future may be subject to future limitations.

U.S. holders of our ordinary shares could be subject to material adverse tax consequences if we are considered a Passive Foreign Investment Company, or PFIC, for U.S. federal income tax purposes.

We do not believe that we were a PFIC for U.S. federal income tax purposes during the tax year ending March 31, 2018 and do not expect to be a PFIC for U.S. federal income tax purposes in the tax year. We also do not expect to become a PFIC in the foreseeable future, but the possible status as a PFIC must be determined annually and therefore may be subject to change. If we are at any time treated as a PFIC, such treatment could result in a reduction in the after-tax return to U.S. holders of our ordinary shares and may cause a reduction in the value of such shares. Furthermore, if we are at any time treated as a PFIC, U.S. holders of our ordinary shares could be subject to greater U.S. income tax liability than might otherwise apply, imposition of U.S. income tax in advance of when tax would otherwise apply and detailed tax filing requirements that would not otherwise apply. For U.S. federal income tax purposes, “U.S. holders” include individuals and various entities. A corporation is classified as a PFIC for any taxable year in which (i) at least 75% of its gross income is passive income or (ii) at least 50% of the average quarterly value of all its total gross assets is attributable to assets that produce or are held for the production of passive income. For this purpose, passive income includes certain dividends, interest, royalties and rents that are not derived in the active conduct of a trade or business. The PFIC rules are complex and a U.S. holder of our ordinary shares is urged to consult its own tax advisors regarding the possible application of the PFIC rules to it in its particular circumstances.

Certain of our directors and executive officers are not residents of the United States, and all or a substantial portion of the assets of such persons are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon such persons or to enforce against them judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the United States.

There is also a doubt as to the enforceability in England and Wales and Jersey, whether by original actions or by seeking to enforce judgments of U.S. courts, of claims based on the federal securities laws of the United States. In addition, punitive damages in actions brought in the United States or elsewhere may be unenforceable in England and Wales and Jersey.

The rights afforded to shareholders are governed by Jersey law. Not all rights available to shareholders under English law or U.S. law will be available to shareholders.

The rights afforded to shareholders will be governed by Jersey law and by our Articles of Association, and these rights differ in certain respects from the rights of shareholders in typical English companies and U.S. corporations. In particular, Jersey law significantly limits the circumstances under which shareholders of companies may bring derivative actions and, in most cases, only the corporation may be the proper claimant or plaintiff for the purposes of maintaining proceedings in respect of any wrongful act committed against it. Neither an individual nor any group of shareholders has any right of action in such circumstances. In addition, Jersey law does not afford appraisal rights to dissenting shareholders in the form typically available to shareholders of a U.S. corporation.

The exhibits required by Item 601 of Regulation S-K are listed in the Exhibit List on the following page.
