Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying interim condensed consolidated balance sheet as of October 31, 2019, the interim condensed consolidated statements of operations and of comprehensive loss, interim condensed statements of redeemable convertible preference shares and shareholders’ equity (deficit) for the three and six months ended October 31, 2019 and 2018 and the interim condensed consolidated statements of cash flows for the six months ended October 31, 2019 and 2018, are unaudited. These interim condensed consolidated financial statements have been prepared on a basis consistent with the annual consolidated financial statements and, in the opinion of management, include all adjustments necessary to fairly state the Company’s financial position as of October 31, 2019 and the results of the Company’s operations, its statements of redeemable convertible preference shares and shareholders’ equity (deficit) statements of cash flows for the six months ended October 31, 2019 and 2018 The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the financial statements of the Company and its wholly owned subsidiaries. All intercompany transactions and accounts have been eliminated in consolidation. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Therefore, these unaudited interim condensed consolidated financial statements and accompanying footnotes should be read in conjunction with the Company’s annual consolidated financial statements and related footnotes included in its Annual Report on Form 10-K for the fiscal year ended April 30, 2019 filed with the SEC on June 28, 2019. Fiscal Year The Company’s fiscal year ends on April 30. References to fiscal 2020, for example, refer to the fiscal year ending April 30, 2020. Use of Estimates and Judgments The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Such estimates include, but are not limited to, allocation of revenue between recognized and deferred amounts, deferred contract acquisition costs, allowance for doubtful accounts, valuation of stock-based compensation, fair value of ordinary shares in periods prior to the Company’s initial public offering (“IPO”), fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, whether an arrangement is or contains a lease, the discount rate used for operating leases and valuation allowance for deferred income taxes. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates. Reclassifications Certain prior period amounts in the statement of cash flows have been reclassified in order to conform to the current period presentation. These reclassifications had no effect on the previously reported net loss. Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has irrevocably elected not to avail itself of this exemption from new or revised accounting standards and, therefore, the Company will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. On the last business day of the Company’s second quarter in fiscal 2020, the aggregate market value of the Company’s ordinary shares held by its non-affiliate shareholders exceeded $700 million. As a result, as of April 30, 2020, the Company will be considered a large accelerated filer as defined in Rule 12b-2 under the Securities Exchange Act of 1934, and the Company will cease to be an emerging growth company as defined in the JOBS Act. The Company will no longer be exempt from the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002, as amended, and the Company’s independent registered public accounting firm will evaluate and report on the effectiveness of internal control over financial reporting. Significant Accounting Policies Other than as described below, there have been no changes to the Company’s significant accounting policies described in its Annual Report on Form 10-K that have had a material impact on its consolidated financial statements and related notes. Leases Leases arise from contractual obligations that convey the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company determines whether an arrangement is or contains a lease at inception, based on whether there is an identified asset and whether the Company controls the use of the identified asset throughout the period of use. At the lease commencement date, the Company determines the lease classification between finance and operating and recognizes a right-of-use asset and corresponding lease liability for each lease component. A right-of-use asset represents the Company’s right to use an underlying asset and a lease liability represents the Company’s obligation to make payments during the lease term. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company accounts for lease components and non-lease components as a single lease component. The lease liability is initially measured as the present value of the remaining lease payments over the lease term. The discount rate used to determine the present value is the Company’s incremental borrowing rate unless the interest rate implicit in the lease is readily determinable. The Company estimates its incremental borrowing rate based on the information available at lease commencement date for borrowings with a similar term. The right-of-use asset is initially measured as the present value of the lease payments, adjusted for initial direct costs, prepaid lease payments to lessors and lease incentives. Deferred contract acquisition costs Deferred contract acquisition costs represent costs that are incremental to the acquisition of customer contracts, which consist mainly of sales commissions and associated payroll taxes. The Company determines whether costs should be deferred based on sales compensation plans, if the commissions are in fact incremental and would not have occurred absent the customer contract. Effective May 1, 2019, the Company updated its sales commissions plan by incorporating different commission rates for initial subscription contract sales and subsequent subscription renewals. Subsequent to this change, sales commissions for renewal of a subscription contract are not considered commensurate with the commissions paid for the acquisition of the initial subscription contract given the substantive difference in commission rates in proportion to their respective contract values. Effective May 1, 2019, commissions paid upon the initial acquisition of a contract are amortized over an estimated period of benefit of five years while commissions paid for renewal contracts are amortized . Deferred contract acquisition costs are expensed commensurate with the pattern of revenue recognition as performance obligations are satisfied. Amortization of deferred contract acquisition costs is recognized in sales and marketing expense in the consolidated statement of operations. The Company periodically reviews the carrying amount of deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these deferred costs. Further disclosures with respect to the Company’s deferred contract acquisition costs are also included in Note 6, Balance Sheet Components. Customer Deposits Certain of the Company’s contracts, acquired via the Endgame, Inc. (“Endgame”) acquisition, allow for termination at the customer’s convenience, or the Company may receive prepayments on master sales agreements. In these cases, the Company does not consider a contract to exist past the term in which enforceable rights and obligations exist. Amounts received related to these agreements are classified outside of deferred revenue in the consolidated balance sheet, and these amounts do not represent contract balances. As of October 31, 2019, the Company had $2.7 million of customer deposits included in accrued expenses and other liabilities, and $9.1 million of non-refundable customer deposits included in other liabilities, non-current on the consolidated balance sheet. Recently Adopted Accounting Pronouncements Leases: In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-02, codified as Accounting Standards Codification 842 (“ASC 842”), which requires lessees to record the assets and liabilities arising from all leases, with the exception of short-term leases, on the balance sheet. Under ASC 842, lessees recognize a liability for lease payments and a right-of-use asset. This guidance retains the distinction between finance leases and operating leases and the classification criteria for finance leases remains similar. For finance leases, a lessee recognizes the interest on a lease liability separate from amortization of the right-of-use asset. In addition, repayments of the principal amount are presented within financing activities, and interest payments are presented within operating activities in the statement of cash flows. For operating leases, a lessee recognizes a single lease cost on a straight-line basis and classifies all cash payments within operating activities in the statement of cash flows. The Company adopted the new lease accounting standard effective May 1, 2019 using the additional transition method described in ASU No. 2018-11, Leases – Targeted Improvements • the package of practical expedients which allows for not reassessing (1) whether existing contracts contain leases, (2) the lease classification for existing leases, and (3) whether existing initial direct costs meet the new definition, • the practical expedient in ASC Subtopic 842-10 to not separate non-lease components from lease components and instead account for each separate lease component and non-lease components associated with that lease component as a single lease component by class of the underlying asset, and • not to recognize right-of-use assets and lease liabilities for short-term leases, which have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. The adoption of ASC 842 resulted in recognition of right-of-use assets of $28.1 million, which included the impact of existing deferred rents of $1.0 million, prepaid rent of $0.2 million and lease liabilities of $28.9 million as of May 1, 2019. See Note 8, Leases The adoption of the new lease accounting standard had no impact on cash provided by or used in operating, investing or financing activities in the Company’s condensed consolidated statements of cash flows. The adoption of the new lease accounting standard did not impact the Company’s condensed consolidated statements of operations nor previously reported financial results. New Accounting Pronouncements Not Yet Adopted Credit Losses: In June 2016, the FASB issued ASU No. 2016-13, , and has since issued various amendments including ASU No. 2018-19, ASU No. 2019-04, and ASU No. 2019-05. The standard and related amendments modify the accounting for credit losses for most financial assets and require the use of an expected loss model, replacing the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021, though early adoption is permitted. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements. Goodwill Impairment : In January 2017, the FASB issued ASU No. 2017-04, . The new standard will simplify the measurement of goodwill by eliminating step two of the two-step impairment test. Step two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. The new guidance requires an entity to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021, though early adoption is permitted. The Company does not expect the adoption of the new accounting standard will have a material impact on its consolidated financial statements. Fair Value Measurements: In August 2018, the FASB issued ASU No. 2018-13, , which modifies, removes and adds certain disclosure requirements on fair value measurements based on the FASB Concepts Statement, . The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021 . Early adoption is permitted. The Company does not expect the adoption of the new accounting standard will have a material impact on its consolidated financial statements. Intangible Assets: In August 2018, the FASB issued ASU No. 2018-15, , which align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this ASU. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021, though early adoption is permitted. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements The Company measures financial assets and liabilities that are measured at fair value on a recurring basis at each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table summarizes assets that are measured at fair value on a recurring basis as of October 31, 2019 and April 30, 2019 (in thousands): October 31, 2019 Level 1 Level 2 Level 3 Total Financial Assets: Cash and cash equivalents: Money market funds $ 225,814 $ - $ - $ 225,814 April 30, 2019 Level 1 Level 2 Level 3 Total Financial Assets: Cash and cash equivalents: Money market funds $ 261,864 $ - $ - $ 261,864 Money market funds consist of cash equivalents with remaining maturities of three months or less at the date of purchase. The Company uses quoted prices in active markets for identical assets to determine the fair value of its Level 1 investments in money market funds.

Acquisitions	5. Acquisitions Six Months Ended October 31, 2019 Endgame, Inc. On October 8, 2019, the Company acquired all outstanding shares of Endgame, a security company offering endpoint protection technology, for a total acquisition price of $234.0 million . Elastic paid the purchase price through (i) the issuance of 2,218,694 ordinary shares in respect of Endgame’s outstanding capital stock, warrants, convertible notes, and certain retention awards, (ii) the cash repayment of Endgame’s outstanding indebtedness of $20.4 million, (iii) the assumption of Endgame’s outstanding stock options, (iv) a $0.4 million cash deposit to an expense fund for the fees and expenses of the representative and agent of Endgame securityholders, (v) the cash payment of Endgame’s transaction expenses of $5.9 million, and (vi) the cash payment of . Approximately 11% of the ordinary shares issued, or 235,031 shares, is being held in an indemnity escrow fund for 18 months after the acquisition close date. For purposes of determining the total acquisition price of $234.0 million, the Company used the ordinary share price of $89.3836 which was determined on the basis of the volume weighted average price per share rounded to four decimal places for the twenty (20) consecutive trading days ending with the complete trading day ending five (5) trading days prior to the date upon which the acquisition was consummated. The fair value of the shares transferred as consideration was $84.12 per share and was determined on the basis of the closing stock price of the Company’s ordinary shares on the date of acquisition. The stock options assumed on the acquisition date will continue to vest as the Endgame employees provide services in the post-acquisition period. The fair value of these awards will be recorded as share-based compensation expense over the respective The Company continues to collect information with regards to its estimates and assumptions, including potential liabilities, contingencies, and the allocation of the purchase price. The Company will record adjustments to the fair value of the net assets acquired, liabilities assumed and goodwill within the measurement period, if necessary.

Customer relationships consists of contracts with platform users that purchase Endgame’s products and services that carry distinct value. Trade names represent the Company’s right to the Endgame trade names and associated design, as it exists as of the acquisition closing date. The fair value assigned to developed technology was determined primarily using the multi-period excess earnings model, which estimates the revenue and cash flows derived from the asset and then deducts portions of the cash flow that can be attributed to supporting assets otherwise recognized. The fair value of the Company’s customer relationships was determined using the income approach, which discounts expected future cash flows to present value using estimates and assumptions determined by management. The fair value assigned to trade name was determined using the relief from royalty method, where the owner of the asset realizes a benefit from owning the intangible asset rather than paying a rental or royalty rate for use of the asset. Recognized goodwill of $179.2 million is not deductible for tax purposes and is primarily attributed to planned growth in new markets, synergies arising from the acquisition and the value of the acquired workforce. Net tangible assets and liabilities assumed were valued at their respective carrying amounts as of the acquisition date, as the Company believes that these amounts approximate their current fair values. Endgame has been included in the Company’s consolidated results of operations since the acquisition date. Endgame’s results were immaterial to the Company’s consolidated results for the three months ended October 31, 2019. The following unaudited pro forma condensed consolidated financial information gives effect to the acquisition of Endgame as if it were consummated on May 1, 2018 (the beginning of the comparable prior reporting period), including pro forma adjustments related to the valuation and allocation of the purchase price, primarily amortization of acquired intangible assets and deferred revenue fair value adjustments; share-based compensation expense; alignment of accounting policies; the impact of applying ASC Topic 606, Revenue From Contracts With Customers, Three Months Ended October 31, Six Months Ended October 31, 2019 2018 2019 2018 Revenue $ 105,450 $ 66,808 $ 200,854 $ 127,676 Net loss $ (46,309 ) $ (36,354 ) $ (94,663 ) $ (77,264 ) Non-recurring acquisition costs incurred by the Company of $17.0 million, including a non-cash expense settled in the Company’s ordinary shares for $8.8 million and a related cash payment of withholding taxes of $2.8 million, were charged to general and administrative expenses in the condensed consolidated statement of operations for the six months ended October 31, 2019, and are reflected in the pro forma net loss presented above for the six months ended October 31, 2018. Non-recurring acquisition costs incurred by Endgame of $1.5 million are also reflected in the pro forma net loss presented above for the six months ended October 31, 2018. Six Months Ended October 31, 2018 Lambda Lab Corp. In July 2018, the Company acquired 100% of the share capital of Lambda Lab Corp. (“Lambda Lab”), a privately held company headquartered in the United States. Lambda Lab was a code search company whose product was built on top of Elasticsearch and focused on building semantic understanding of code, exposed through powerful search features. Purchase consideration for the acquisition was $2.0 million in cash. Excluded from the purchase consideration are 134,474 ordinary shares of $2.2 million issued to certain employees of Lambda Lab. These shares are subject to repurchase until the two year anniversary of the close of the acquisition and are contingent upon these employees’ continued employment with the Company. The repurchase option lapses as to fifty percent of the ordinary shares on each anniversary of the close of the acquisition. The Company will record stock-based compensation expense of $2.2 million over the two year vesting term. During both the six months ended October 31, 2018 and 2019, the Company recorded stock-based compensation expense of $0.5 million. As of October 31, 2019, a share repurchase liability, included in accrued expenses was $1.1 million. As of October 31, 2019, the deferred stock-based compensation expense included in prepaid expenses and other current assets was $0.4 million. The following table summarizes the components of the Lambda Lab purchase price and the preliminary allocation of the purchase price at fair value (in thousands): Cash paid $ 1,997 Developed technology $ 1,339 Trade name 15 Goodwill 1,038 Net liabilities acquired (395 ) Total purchase consideration $ 1,997 The amount allocated to developed technology was $1.3 million. The fair value assigned to developed technology was determined primarily using the multi-period excess earnings model, which estimates the revenue and cash flows derived from the asset and then deducts portions of the cash flow that can be attributed to supporting assets otherwise recognized. The acquired developed technology is being amortized on a straight-line basis over four years, which approximates the pattern in which these assets are utilized. Goodwill of $1.0 million, none of which is deductible for tax purposes, was recorded in connection with the Lambda Lab acquisition, which is primarily attributed to synergies arising from the acquisition and the value of the acquired workforce. Acquisition costs of $0.2 million were charged to general and administrative expenses in the consolidated statement of operations for the six months ended October 31, 2018. Lambda Lab has been included in the Company’s consolidated results of operations since the acquisition date. Fair Value of Ordinary Shares Used for Purchase Consideration The fair value of the ordinary shares issued as part of the consideration paid for the above acquisition was determined by the Company’s board of directors based on numerous subjective and objective factors, including, but not limited to, a contemporaneous valuation performed by an independent third-party valuation firm. Because the Company was not publicly traded at the time the acquisition was completed, the Company’s board of directors considered valuations of comparable companies, sales of redeemable convertible preference shares, sales of ordinary shares to unrelated third parties, operating and financial performance, the lack of liquidity of the Company’s ordinary shares, and general and industry-specific economic outlook, among other factors.

For annual contracts, the Company typically invoices customers at the time of entering into the contract. For multi-year agreements, the Company generally invoices customers on an annual basis prior to each anniversary of the contract start date. The Company records unbilled accounts receivable related to revenue recognized in excess of amounts invoiced as the Company has an unconditional right to invoice and receive payment in the future related to those fulfilled obligations. Invoicing customers prior to performance creates a contract liability, deferred revenue, which is recognized in accordance with the Company’s revenue recognition policy. The following table provides information about unbilled accounts receivable, deferred contract acquisition costs and deferred revenue from contracts with customers (in thousands): As of October 31, 2019 As of April 30, 2019 Unbilled accounts receivable, included in accounts receivable, net $ 2,630 $ 1,710 Deferred contract acquisition costs $ 29,234 $ 26,150 Deferred revenue $ 201,331 $ 170,666 Significant changes in the unbilled accounts receivable and the deferred revenue balances were as follows (in thousands): Unbilled Accounts Receivable Six Months Ended October 31, 2019 2018 Beginning balance $ 1,710 $ 1,139 Amounts transferred to accounts receivable from unbilled accounts receivable presented at the beginning of the period (1,710 ) (1,139 ) Additions through acquisition 321 - Revenue recognized during the period in excess of invoices issued 2,309 1,294 Ending balance $ 2,630 $ 1,294 Deferred Revenue Six Months Ended October 31, 2019 2018 Beginning balance $ 170,666 $ 102,561 Increases due to invoices issued, excluding amounts recognized as revenue during the period 135,665 94,830 Increase from acquisition, net of revenue recognized 6,147 - Revenue recognized that was included in deferred revenue balance at beginning of period (111,147 ) (70,112 ) Ending balance $ 201,331 $ 127,279 Deferred Contract Acquisition Costs During the six months ended October 31, 2018 and the fiscal year ending April 30, 2019, sales commissions for renewal of a contract were considered commensurate with the commissions paid for the acquisition of the initial contract given there was no substantive difference in commission rates in proportion to their respective contract values. During the six months ended October 31, 2019, the Company updated its sales commissions plan by incorporating different commission rates for initial subscription contract sales and subsequent subscription renewals. Subsequent to this change, sales commissions for renewal of a subscription contract are not considered commensurate with the commissions paid for the acquisition of the initial subscription contract given the substantive difference in commission rates in proportion to their respective contract values. Accordingly, commissions paid upon the initial acquisition of a contract are now amortized over an estimated period of benefit of five years while commissions paid related to renewal contracts are now amortized . Deferred contract acquisition costs are expensed commensurate with the pattern of revenue recognition as performance obligations are satisfied. Amortization of deferred contract acquisition costs is recognized in sales and marketing expense in the consolidated statement of operations. The Company periodically reviews the carrying amount of deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these deferred costs. The Company did not recognize any impairment of deferred contract acquisition costs during the six months ended October 31, 2019. The following table summarizes the activity of the deferred contract acquisition costs (in thousands): Six Months Ended October 31, 2019 2018 Beginning balance $ 26,150 $ 18,079 Capitalization of contract acquisition costs 17,005 13,637 Amortization of deferred contract acquisition costs (13,921 ) (8,848 ) Ending balance $ 29,234 $ 22,868

Commitments and Contingencies	7. Commitments and Contingencies Hosting Infrastructure Commitments In December 2017, the Company entered into non-cancelable capacity commitments with a hosting infrastructure vendor for a total minimum commitment of $12.5 million in each of the subsequent three years. In December 2018, the agreement was amended to establish total minimum commitments of $17.0 million for calendar year 2019, $20.0 million for calendar year 2020 and $23.0 million for calendar year 2021. As of October 31, 2019, the Company had paid all of the $17.0 million toward the calendar year 2019 commitment. Hosting infrastructure commitments as of October 31, 2019 were as follows (in thousands): Years Ending April 30, 2020 (remaining six months) $ 6,667 2021 21,000 2022 15,333 Total $ 43,000 Letters of Credit The Company had a total of $2.3 million in letters of credit outstanding in favor of certain landlords for office space as of October 31, 2019. Legal Matters From time to time, the Company has become involved in claims and other legal matters arising in the ordinary course of business. The Company investigates these claims as they arise. Although claims are inherently unpredictable, the Company is currently not aware of any matters that, if determined adversely to the Company, would individually or taken together have a material adverse effect on its business, results of operations, financial position or cash flows. The Company accrues estimates for resolution of legal and other contingencies when losses are probable and estimable. Although the results of litigation and claims are inherently unpredictable, the Company believes that there was not at least a reasonable possibility that the Company had incurred a material loss with respect to such loss contingencies, as of October 31, 2019; therefore, the Company has not recorded an accrual for such contingencies. Indemnification The Company enters into indemnification provisions under its agreements with other companies in the ordinary course of business, including business partners, landlords, contractors and parties performing its research and development. Pursuant to these arrangements, the Company agrees to indemnify, hold harmless, and reimburse the indemnified party for certain losses suffered or incurred by the indemnified party as a result of the Company’s activities. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the fair value of these agreements is not material. The Company maintains commercial general liability insurance and product liability insurance to offset certain of the Company’s potential liabilities under these indemnification provisions. In addition, the Company indemnifies its officers, directors and certain key employees while they are serving in good faith in their respective capacities. To date, there have been no claims under any indemnification provisions.

Equity Incentive Plans	10. Equity Incentive Plans I n September 2012, the Company’s board of directors adopted and the Company’s shareholders approved the 2012 Stock Option Plan, which was amended and restated in September 2018 (as amended and restated, the “2012 Plan”). to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to employees, directors and consultants, and to promote the success of the Company’s business ’s board of directors or compensation committee determines the vesting schedule for all equity-based awards. Equity settled RSUs granted to new employees generally vest over a period of four years with 25% vesting on the one-year anniversary of the vesting start date and the remainder vesting semi-annually over the next three years, subject to the grantee’s continued service to the Company. Equity settled RSUs granted to existing employees generally vest semi-annually over a period of four years, subject to the grantee’s continued service to the Company. The Company’s compensation commit The equity awards available for grant for the periods presented were as follows: Six Months Ended October 31, 2019 Available at beginning of period 9,649,123 Awards authorized 3,683,754 Stock options granted (172,031 ) Stock options cancelled 443,367 RSUs granted (474,677 ) RSUs cancelled 58,992 RSAs cancelled 4,585 Available at end of period 13,193,113 Endgame Stock Incentive Plan Assumed in Acquisition In connection with its acquisition of Endgame, the Company assumed all in-the-money stock options issued under Endgame’s Amended and Restated 2010 Stock Incentive Plan that were outstanding on the date of acquisition. The assumed stock options will continue to be outstanding and will be governed by the provisions of their respective plan and are included in the stock option activity table below. Stock Options The following table summarizes stock option activity (in thousands, except share and per share data): Stock options Outstanding Number of Stock Options Outstanding Weighted- Average Exercise Price Remaining Contractual Term (in years) Aggregate Intrinsic Value Balance as of April 30, 2019 22,866,438 $ 11.90 7.98 $ 1,684,106 Stock options granted 172,031 $ 81.39 Stock options assumed in acquisition 245,390 $ 48.99 Stock options exercised (4,470,226 ) $ 8.85 Stock options cancelled (443,674 ) $ 15.08 Balance as of October 31, 2019 18,369,959 $ 13.71 7.56 $ 1,073,648 Exercisable as of October 31, 2019 8,138,191 $ 9.93 6.78 $ 505,284 Stock options exercisable include 493,808 stock options that were unvested as of October 31, 2019. Aggregate intrinsic value represents the difference between the exercise price of the stock options to purchase ordinary shares and the fair value of the Company’s ordinary shares. The weighted-average grant-date fair value per share of stock options granted was $54.20 and $10.69 for the three months ended October 31, 2019 and 2018, respectively and $50.92 and $9.09 for the six months ended October 31, 2019 and 2018, respectively. As of October 31, 2019, the Company had unrecognized stock-based compensation expense of $73.8 million related to unvested stock options that the Company expects to recognize over a weighted-average period of 2.52 years. RSAs I n October 2017, the Company acquired 100% of the share capital of Swiftype, Inc. (“Swiftype”), a privately-held company headquartered in the United States. As part of the transaction, t The performance-based vesting condition related to these awards was deemed probable upon the effectiveness of the Company’s IPO on October 8, 2018. On that date, the Company recorded a cumulative catch-up stock-based compensation expense using the accelerated attribution method for the RSAs that had satisfied the applicable service-based vesting condition on that date with the remaining expense to be recognized over the remaining requisite service period. As of October 31, 2019, the underlying performance-based and service-based vesting conditions were fully satisfied and none of the ordinary shares issued were subject to repurchase by the Company. Stock-based compensation expense related to the RSAs for the three and six month period ended October 31, 2019 was $0.1 million and $0.2 million, respectively. RSUs During the six months ended October 31, 2019, the Company granted 474,677 RSUs at a weighted average grant date fair value of $83.19 per unit, including 1,388 RSUs that are cash settled. Cash settled RSUs will be paid as a cash bonus based on the applicable vesting and payment terms. The cash settled RSUs vest upon the satisfaction of both service-based and performance-based vesting conditions. The service-based vesting condition is generally over four years with 25% vesting on the one-year anniversary of the award and the remainder vesting quarterly over the next 36 months, subject to the grantee’s continued service to the Company. The performance-based vesting condition is defined as (i) a change in control where the consideration paid to the Company’s equity security holders is cash, publicly traded stock, or a combination of both, or (ii) the expiration of any lock-up period of the IPO, subject in each instance to the grantee’s continued service through such date. As a result of the Company’s IPO, the performance-based vesting condition was deemed probable and the Company recorded cumulative stock-based compensation expense related to the cash settled RSUs in October 2018. As of October 31, 2019, the Company had a liability of million related to the cash settled RSUs recorded in accrued compensation and benefits on the condensed consolidated balance sheet.

Basis of Presentation	Basis of Presentation The accompanying interim condensed consolidated balance sheet as of October 31, 2019, the interim condensed consolidated statements of operations and of comprehensive loss, interim condensed statements of redeemable convertible preference shares and shareholders’ equity (deficit) for the three and six months ended October 31, 2019 and 2018 and the interim condensed consolidated statements of cash flows for the six months ended October 31, 2019 and 2018, are unaudited. These interim condensed consolidated financial statements have been prepared on a basis consistent with the annual consolidated financial statements and, in the opinion of management, include all adjustments necessary to fairly state the Company’s financial position as of October 31, 2019 and the results of the Company’s operations, its statements of redeemable convertible preference shares and shareholders’ equity (deficit) statements of cash flows for the six months ended October 31, 2019 and 2018 The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the financial statements of the Company and its wholly owned subsidiaries. All intercompany transactions and accounts have been eliminated in consolidation. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Therefore, these unaudited interim condensed consolidated financial statements and accompanying footnotes should be read in conjunction with the Company’s annual consolidated financial statements and related footnotes included in its Annual Report on Form 10-K for the fiscal year ended April 30, 2019 filed with the SEC on June 28, 2019.
Fiscal Year	Fiscal Year The Company’s fiscal year ends on April 30. References to fiscal 2020, for example, refer to the fiscal year ending April 30, 2020.
Use of Estimates and Judgments	Use of Estimates and Judgments The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Such estimates include, but are not limited to, allocation of revenue between recognized and deferred amounts, deferred contract acquisition costs, allowance for doubtful accounts, valuation of stock-based compensation, fair value of ordinary shares in periods prior to the Company’s initial public offering (“IPO”), fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, whether an arrangement is or contains a lease, the discount rate used for operating leases and valuation allowance for deferred income taxes. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates.
Reclassifications	Reclassifications Certain prior period amounts in the statement of cash flows have been reclassified in order to conform to the current period presentation. These reclassifications had no effect on the previously reported net loss.
Emerging Growth Company Status	Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has irrevocably elected not to avail itself of this exemption from new or revised accounting standards and, therefore, the Company will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. On the last business day of the Company’s second quarter in fiscal 2020, the aggregate market value of the Company’s ordinary shares held by its non-affiliate shareholders exceeded $700 million. As a result, as of April 30, 2020, the Company will be considered a large accelerated filer as defined in Rule 12b-2 under the Securities Exchange Act of 1934, and the Company will cease to be an emerging growth company as defined in the JOBS Act. The Company will no longer be exempt from the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002, as amended, and the Company’s independent registered public accounting firm will evaluate and report on the effectiveness of internal control over financial reporting.
Significant Accounting Policies	Significant Accounting Policies Other than as described below, there have been no changes to the Company’s significant accounting policies described in its Annual Report on Form 10-K that have had a material impact on its consolidated financial statements and related notes.
Leases	Leases Leases arise from contractual obligations that convey the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company determines whether an arrangement is or contains a lease at inception, based on whether there is an identified asset and whether the Company controls the use of the identified asset throughout the period of use. At the lease commencement date, the Company determines the lease classification between finance and operating and recognizes a right-of-use asset and corresponding lease liability for each lease component. A right-of-use asset represents the Company’s right to use an underlying asset and a lease liability represents the Company’s obligation to make payments during the lease term. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company accounts for lease components and non-lease components as a single lease component. The lease liability is initially measured as the present value of the remaining lease payments over the lease term. The discount rate used to determine the present value is the Company’s incremental borrowing rate unless the interest rate implicit in the lease is readily determinable. The Company estimates its incremental borrowing rate based on the information available at lease commencement date for borrowings with a similar term. The right-of-use asset is initially measured as the present value of the lease payments, adjusted for initial direct costs, prepaid lease payments to lessors and lease incentives.
Deferred Contract Acquisition Costs	Deferred contract acquisition costs Deferred contract acquisition costs represent costs that are incremental to the acquisition of customer contracts, which consist mainly of sales commissions and associated payroll taxes. The Company determines whether costs should be deferred based on sales compensation plans, if the commissions are in fact incremental and would not have occurred absent the customer contract. Effective May 1, 2019, the Company updated its sales commissions plan by incorporating different commission rates for initial subscription contract sales and subsequent subscription renewals. Subsequent to this change, sales commissions for renewal of a subscription contract are not considered commensurate with the commissions paid for the acquisition of the initial subscription contract given the substantive difference in commission rates in proportion to their respective contract values. Effective May 1, 2019, commissions paid upon the initial acquisition of a contract are amortized over an estimated period of benefit of five years while commissions paid for renewal contracts are amortized . Deferred contract acquisition costs are expensed commensurate with the pattern of revenue recognition as performance obligations are satisfied. Amortization of deferred contract acquisition costs is recognized in sales and marketing expense in the consolidated statement of operations. The Company periodically reviews the carrying amount of deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these deferred costs. Further disclosures with respect to the Company’s deferred contract acquisition costs are also included in Note 6, Balance Sheet Components.
Customer Deposits	Customer Deposits Certain of the Company’s contracts, acquired via the Endgame, Inc. (“Endgame”) acquisition, allow for termination at the customer’s convenience, or the Company may receive prepayments on master sales agreements. In these cases, the Company does not consider a contract to exist past the term in which enforceable rights and obligations exist. Amounts received related to these agreements are classified outside of deferred revenue in the consolidated balance sheet, and these amounts do not represent contract balances. As of October 31, 2019, the Company had $2.7 million of customer deposits included in accrued expenses and other liabilities, and $9.1 million of non-refundable customer deposits included in other liabilities, non-current on the consolidated balance sheet.
Recently Adopted Accounting Pronouncements and New Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements Leases: In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-02, codified as Accounting Standards Codification 842 (“ASC 842”), which requires lessees to record the assets and liabilities arising from all leases, with the exception of short-term leases, on the balance sheet. Under ASC 842, lessees recognize a liability for lease payments and a right-of-use asset. This guidance retains the distinction between finance leases and operating leases and the classification criteria for finance leases remains similar. For finance leases, a lessee recognizes the interest on a lease liability separate from amortization of the right-of-use asset. In addition, repayments of the principal amount are presented within financing activities, and interest payments are presented within operating activities in the statement of cash flows. For operating leases, a lessee recognizes a single lease cost on a straight-line basis and classifies all cash payments within operating activities in the statement of cash flows. The Company adopted the new lease accounting standard effective May 1, 2019 using the additional transition method described in ASU No. 2018-11, Leases – Targeted Improvements • the package of practical expedients which allows for not reassessing (1) whether existing contracts contain leases, (2) the lease classification for existing leases, and (3) whether existing initial direct costs meet the new definition, • the practical expedient in ASC Subtopic 842-10 to not separate non-lease components from lease components and instead account for each separate lease component and non-lease components associated with that lease component as a single lease component by class of the underlying asset, and • not to recognize right-of-use assets and lease liabilities for short-term leases, which have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. The adoption of ASC 842 resulted in recognition of right-of-use assets of $28.1 million, which included the impact of existing deferred rents of $1.0 million, prepaid rent of $0.2 million and lease liabilities of $28.9 million as of May 1, 2019. See Note 8, Leases The adoption of the new lease accounting standard had no impact on cash provided by or used in operating, investing or financing activities in the Company’s condensed consolidated statements of cash flows. The adoption of the new lease accounting standard did not impact the Company’s condensed consolidated statements of operations nor previously reported financial results. New Accounting Pronouncements Not Yet Adopted Credit Losses: In June 2016, the FASB issued ASU No. 2016-13, , and has since issued various amendments including ASU No. 2018-19, ASU No. 2019-04, and ASU No. 2019-05. The standard and related amendments modify the accounting for credit losses for most financial assets and require the use of an expected loss model, replacing the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021, though early adoption is permitted. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements. Goodwill Impairment : In January 2017, the FASB issued ASU No. 2017-04, . The new standard will simplify the measurement of goodwill by eliminating step two of the two-step impairment test. Step two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. The new guidance requires an entity to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021, though early adoption is permitted. The Company does not expect the adoption of the new accounting standard will have a material impact on its consolidated financial statements. Fair Value Measurements: In August 2018, the FASB issued ASU No. 2018-13, , which modifies, removes and adds certain disclosure requirements on fair value measurements based on the FASB Concepts Statement, . The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021 . Early adoption is permitted. The Company does not expect the adoption of the new accounting standard will have a material impact on its consolidated financial statements. Intangible Assets: In August 2018, the FASB issued ASU No. 2018-15, , which align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this ASU. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2021, though early adoption is permitted. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.
