| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation The 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. |
| Fiscal Year | Fiscal Year The Company’s fiscal year ends on April 30. References to fiscal 2021, for example, refer to the fiscal year ended April 30, 2021. |
| Use of Estimates and Judgments | Use of Estimates and Judgments The preparation of the 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 credit losses, valuation of stock-based compensation, fair value of ordinary shares in periods prior to the Company’s initial public offering, 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. In March 2020, the World Health Organization declared the 2019 novel Coronavirus Disease (“COVID-19”) a pandemic. The pandemic is expected to result in a global slowdown of economic activity that is likely to decrease demand for a broad variety of goods and services, including from the Company’s customers, while also disrupting sales channels and marketing activities for an unknown period of time. The full extent to which COVID-19 may impact the Company’s financial condition or results of operations is uncertain. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, judgments or revise the carrying value of the Company’s assets or liabilities. These estimates may change, as new events occur and additional information is obtained, |
| Foreign Currency | Foreign Currency The reporting currency of the Company is the U.S. dollar. The Company determines the functional currency of each subsidiary in accordance with ASC 830, Foreign Currency Matters, based on the currency of the primary economic environment in which each subsidiary operates. Items included in the financial statements of such subsidiaries are measured using that functional currency. The Company periodically re-assesses its operations to determine if previous conclusions are still valid. Changes in functional currencies are applied prospectively if the operations encounter a significant and permanent change. For the subsidiaries where the U.S. dollar is the functional currency, foreign currency denominated monetary assets and liabilities are re-measured into U.S. dollars at current exchange rates and foreign currency denominated nonmonetary assets and liabilities are re-measured into U.S. dollars at historical exchange rates. Gains or losses from foreign currency re-measurement and settlements are included in other income (expense), net in the consolidated statement of operations. For the years ended April 30, 2021, 2020 and 2019, the Company recognized a re-measurement gain of $7.7 million, and re-measurement loss of $2.2 million and $0.2 million, respectively. For subsidiaries where the functional currency is other than the U.S. dollar, the Company uses the period-end exchange rates to translate assets and liabilities, the average monthly exchange rates to translate revenue and expenses, and historical exchange rates to translate shareholders’ equity (deficit), into U.S. dollars. The Company records translation gains and losses in accumulated other comprehensive loss as a component of shareholders’ equity in the consolidated balance sheet. |
| Comprehensive Loss | Comprehensive Loss The Company’s comprehensive loss includes net loss and unrealized gains and losses on foreign currency translation adjustments. |
| Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments, including money market funds with an original maturity of three months or less at the date of purchase, to be cash equivalents. The carrying amount of the Company’s cash equivalents approximates fair value, due to the short maturities of these instruments. Restricted cash represents cash on deposit with financial institutions in support of letters of credit in favor of certain landlords for non-cancelable lease agreements. Cash, cash equivalents, and restricted cash as reported in the Company’s consolidated statements of cash flows includes the aggregate amounts of cash and cash equivalents and the restricted cash as shown on the consolidated balance sheet. Cash, cash equivalents, and restricted cash as reported in the Company’s consolidated statements of cash flows consists of the following (in thousands): As of April 30, 2021 2020 Cash and cash equivalents $ 400,814 $ 297,081 Restricted cash 2,894 2,308 Cash, cash equivalents and restricted cash $ 403,708 $ 299,389 |
| Short-Term Investments | Short-Term InvestmentsInvestments with an original maturity of three months or less at the date of purchase are considered cash equivalents, while all other investments are classified as short-term or long-term based on the nature of the investments, their maturities, and their availability for use in current operations. The Company determines the appropriate classification of its investments at the time of purchase and reevaluates such designation at each balance sheet date. Bank deposits with original maturities greater than three months but less than twelve months and are classified as short-term investments within current assets in the consolidated balance sheet. |
| Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company’s financial instruments consist of cash equivalents, accounts receivable, accounts payable, and accrued liabilities. Cash equivalents are stated at amortized cost, which approximates fair value at the balance sheet dates, due to the short period of time to maturity. Accounts receivable, accounts payable and accrued liabilities are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date. Assets and liabilities recorded at fair value on a recurring basis in the consolidated balance sheet consisting primarily of cash equivalents are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company measures its financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value: • Level 1: Observable inputs, such as unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2: Observable inputs, other than Level 1 prices, such as quoted prices in active markets for similar assets and liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying values of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their respective fair values due to the short period of time to maturity, receipt or payment. |
| Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash, cash equivalents, restricted cash, short-term investments, and accounts receivable. The primary focus of the Company’s investment strategy is to preserve capital and meet liquidity requirements. The Company maintains its cash accounts with financial institutions where, at times, deposits exceed federal insurance limits. The Company invests its excess cash in highly-rated money market funds and in short-term investments. The Company extends credit to customers in the normal course of business. The Company performs credit analyses and monitors the financial health of its customers to reduce credit risk. Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Management performs ongoing credit evaluations of customers and maintains allowances for potential credit losses on customers’ accounts when deemed necessary. No customer represented 10% or more of net accounts receivable as of April 30, 2021, and one customer represented 10% of net accounts receivable as of April 30, 2020. No customer accounted for more than 10% of the Company’s total revenue for the years ended April 30, 2021, 2020 and 2019. |
| Accounts Receivable, Unbilled Accounts Receivable and Allowance for Credit Losses | Accounts Receivable, Unbilled Accounts Receivable and Allowance for Credit Losses Accounts receivable primarily consists of amounts billed currently due from customers. The Company’s accounts receivable are subject to collection risk. Gross accounts receivable are reduced for this risk by an allowance for credit losses. This allowance is for estimated losses resulting from the inability of the Company’s customers to make required payments. The Company determines the need for an allowance for credit losses based upon various factors, including past collection experience, credit quality of the customer, age of the receivable balance, and current economic conditions, as well as specific circumstances arising with individual customers. Accounts receivables are written off against the allowance when management determines a balance is uncollectible and the Company no longer actively pursues collection of the receivable. The Company does not typically offer right of refund in its contracts. The allowance for credit losses reflects the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio. As of April 30, 2021 and 2020, the allowance for credit losses was $2.3 million and $1.2 million, respectively. Activity related to the Company’s allowance for credit losses was as follows (in thousands): Year ended April 30, 2021 2020 2019 Beginning balance $ 1,247 $ 1,411 $ 776 Cumulative-effect adjustment from adoption of ASU 2016-13 (367) — — Bad debt expense 5,095 193 1,105 Accounts written off (3,631) (357) (470) Ending balance $ 2,344 $ 1,247 $ 1,411 Unbilled accounts receivable represents amounts for which the Company has recognized revenue, pursuant to the Company’s revenue recognition policy, for fulfilled obligations, but not yet billed. The unbilled accounts receivable balance was $5.2 million and $2.6 million as of April 30, 2021 and 2020, respectively. |
| Capitalized Software Development and Implementation Costs | Capitalized Software Development and Implementation Costs Software development costs for software to be sold, leased, or otherwise marketed are expensed as incurred until the establishment of technological feasibility, at which time those costs are capitalized until the product is available for general release to customers and amortized over the estimated life of the product. Technological feasibility is established upon the completion of a working prototype that has been certified as having no critical bugs and is a release candidate. To date, costs to develop software that is marketed externally have not been capitalized as the current software development process is essentially completed concurrently with the establishment of technological feasibility. As such, all related software development costs are expensed as incurred and included in research and development expense in the consolidated statement of operations. Costs related to software acquired, developed, or modified solely to meet the Company’s internal requirements, with no substantive plans to market such software at the time of development and costs related to the development of web-based product are capitalized during the application development stage. Costs incurred during the preliminary planning and evaluation stage of the project and during the post implementation operational stage are expensed as incurred. Costs incurred during the application development stage of the project are capitalized. No costs were capitalized during the years ended April 30, 2021 and 2020. The Company also capitalizes qualifying implementation costs incurred in a hosting arrangement that is a service contract based on the existing guidance for internally developed software. In accordance with the guidance, (i) capitalized implementation costs are classified in the same balance sheet line item as the amounts prepaid for the related hosting arrangement; (ii) amortization of capitalized implementation costs are presented in the same income statement line item as the service fees for the related hosting arrangement; and (iii) cash flows related to capitalized implementation costs are presented within the same category of cash flow activity as the cash flows for the related hosting arrangement (i.e. operating activity). The Company tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The Company amortizes capitalized implementation costs over the expected life of the service contract. The Company capitalized $0.3 million in implementation costs for software hosting arrangements during the fiscal year ended April 30, 2021. No such costs were capitalized during the fiscal year ended April 30, 2020. No amortization expense related to capitalized implementation costs was recorded during the fiscal years ended April 30, 2021, 2020 and 2019, respectively as the underlying implementation activities were not complete. |
| Property and Equipment | Property and Equipment Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the financial statements and any resulting gain or loss is reflected within the consolidated statement of operations. There was no material gain or loss incurred as a result of retirement or sale in the periods presented. Repair and maintenance costs are expensed as incurred. |
| 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. |
| Acquisitions | Acquisitions The Company has completed a number of acquisitions of other businesses in the past and may acquire additional businesses or technologies in the future. The results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of acquisition. The Company allocates the purchase price, which is the sum of the consideration provided and may consist of cash, equity or a combination of the two, in a business combination to the identifiable assets and liabilities of the acquired business at their acquisition date fair values. The excess of the purchase price over the amount allocated to the identifiable assets and liabilities, if any, is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates, including the selection of valuation methodologies, estimates of future revenue and cash flows, discount rates and selection of comparable companies. When the Company issues stock-based or cash awards to an acquired company’s shareholders, the Company evaluates whether the awards are consideration or compensation for post-acquisition services. The evaluation includes, among other things, whether the vesting of the awards is contingent on the continued employment of the acquired company’s shareholders beyond the acquisition date. If continued employment is required for vesting, the awards are treated as compensation for post- acquisition services and recognized as expense over the requisite service period. To date, the assets acquired and liabilities assumed in the Company’s business combinations have primarily consisted of goodwill and finite-lived intangible assets, consisting primarily of developed technologies, in-process research & development, customer relationships and trade names. The estimated fair values and useful lives of identifiable intangible assets are based on many factors, including estimates and assumptions of future operating performance and cash flows of the acquired business, the nature of the business acquired, and the specific characteristics of the identified intangible assets. The estimates and assumptions used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including market conditions, technological developments, economic conditions and competition. In connection with determination of fair values, the Company may engage independent appraisal firms to assist with the valuation of intangible and certain tangible assets acquired and certain assumed obligations. Acquisition-related transaction costs incurred by the Company are not included as a component of consideration transferred, but are accounted for as an operating expense in the period in which the costs are incurred. |
| Goodwill | Goodwill Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations accounted for using the acquisition method for accounting and is not amortized. The Company tests goodwill for impairment at least annually, in the fourth quarter of each year, or more frequently if events or changes in circumstances indicate that this asset may be impaired. For the purposes of impairment testing, the Company has determined that it has one operating segment and one reporting unit. The Company’s test of goodwill impairment starts with a qualitative assessment to determine whether it is necessary to perform a quantitative goodwill impairment test. If qualitative factors indicate that the fair value of the reporting unit is more likely than not less than its carrying amount, then a quantitative goodwill impairment test is performed. For the quantitative analysis, the Company compares the fair value of its reporting unit to its carrying value. If the estimated fair value exceeds book value, goodwill is considered not to be impaired and no additional steps are necessary. However, if the fair value |
| Acquired Intangible Assets | Acquired Intangible Assets Acquired amortizable intangible assets are amortized on a straight-line basis over the estimated useful lives of the assets. Useful life Developed technology 4-5 Customer relationships 4 Trade names 4 |
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company evaluates the recoverability of long-lived assets, including property and equipment and amortizable acquired intangible assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be fully recoverable. Such events and changes may include: significant changes in performance relative to expected operating results, significant changes in asset use, significant negative industry or economic trends, and changes in the Company’s business strategy. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value. The Company determined that there were no events or changes in circumstances that indicated that its long-lived assets were impaired during the years ended April 30, 2021, 2020 and 2019. In addition to the recoverability assessment, the Company periodically reviews the remaining estimated useful lives of property and equipment and amortizable intangible assets. If the estimated useful life assumption for any asset is changed, the remaining unamortized balance would be depreciated or amortized over the revised estimated useful life, on a prospective basis. |
| Deferred Offering Costs | Deferred Offering CostsDeferred offering costs were capitalized and consisted of fees and expenses incurred in connection with the sale of the Company’s ordinary shares in its IPO, including the legal, accounting, printing and other IPO-related costs. Upon consummation of the IPO in October 2018, $0.2 million of previously deferred offering costs along with additional offering costs of $5.5 million were reclassified to shareholders’ equity and recorded against the proceeds from the offering. |
| Revenue Recognition | Revenue Recognition The Company generates revenue primarily from the sale of self-managed subscriptions (which include licenses for proprietary features, support, and maintenance) and from the sale of SaaS subscriptions. The Company also generates revenue from professional services, which consist of consulting and training. Under ASC Topic 606, Revenue from Contracts with Customers, the Company recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company’s contracts include varying terms and conditions, and identifying and evaluating the impact of these terms and conditions on revenue recognition requires significant judgment. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the Company performs the following steps: (i) identification of the contract with a customer; The Company contracts with its customers through order forms, which in some cases are governed by master sales agreements. The Company determines that it has a contract with a customer when the order form has been approved, each party’s rights regarding the products or services to be transferred can be identified, the payment terms for the services can be identified, the Company has determined the customer has the ability and intent to pay and the contract has commercial substance. The Company applies judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit, reputation and financial or other information pertaining to the customer. At contract inception the Company evaluates whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. The Company has concluded that its contracts with customers do not contain warranties that give rise to a separate performance obligation. (ii) identification of the performance obligations in the contract; Performance obligations promised in a contract are identified based on the products and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the products or services either on their own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the products and services is separately identifiable from other promises in the contract. The Company’s self-managed subscriptions include both license providing the right to use proprietary features in its software, as well as an obligation to provide support (on both open source and proprietary features) and maintenance. The Company’s SaaS products provide access to hosted software as well as support, which the Company considers to be a single performance obligation. Services-related performance obligations relate to the provision of consulting and training services. These services are distinct from subscriptions and do not result in significant customization of the software. (iii) determination of the transaction price; The transaction price is the total amount of consideration we expect to be entitled to in exchange for the subscriptions and services in a contract. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component. (iv) allocation of the transaction price to the performance obligations; and If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. For contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation based on a relative standalone selling price (‘SSP”). The SSP is determined based on the prices at which we separately sell these products assuming the majority of these fall within a pricing range. In instances where SSP is not directly observable, such as when we do not sell the software license separately, we derive the SSP using information that may include market conditions and other observable and unobservable inputs which can require significant judgment. There is typically more than one SSP for individual products and services due to the stratification of those products and services by quantity, term of the subscription, sales channel and other circumstances. If one of the performance obligations is outside of the SSP range, the Company allocates the transaction price considering the midpoint of the SSP range. The Company also considers if there are any additional material rights inherent in a contract, and if so, the Company allocates a portion of the transaction price to such rights based on a relative SSP. (v) recognition of revenue when the Company satisfies each performance obligation; Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised product or service to the customer. The Company’s self-managed subscriptions include both upfront revenue recognition when the license is delivered as well as revenue recognized ratably over the contract period for support and maintenance based on the stand-ready nature of these subscription elements. Revenue on the Company’s SaaS products is recognized ratably over the contract period as the Company satisfies the performance obligation. Professional services comprise consulting services as well as public and private training. Consulting services are generally time-based arrangements. Revenue from professional services is recognized as these services are performed. The Company generates sales directly through its sales team and through its channel partners. Sales to channel partners are made at a discount and revenues are recorded at this discounted price once all the revenue recognition criteria above are met. To the extent that the Company offers rebates, incentives or joint marketing funds to such channel partners, recorded revenues are reduced by this amount. Channel partners generally receive an order from an end-customer prior to placing an order with the Company. Payment from channel partners is not contingent on the partner’s collection from end-customers. |
| Contract Balances | Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers. 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. Contract liabilities consist of deferred revenue which is recognized over the contractual period. |
| 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. During the fiscal year ended April 30, 2020, the Company updated its sales commissions plan by incorporating different commission rates for contracts with new customers and incremental sales to existing customers, 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 contracts with new customers and incremental sales to existing customers given the substantive difference in commission rates in proportion to their respective contract values. Effective May 1, 2019, commissions paid for contracts with new customers and incremental sales to existing customers are amortized over an estimated period of benefit of five years while commissions paid for renewal contracts are amortized based on the pattern of the associated revenue recognition over the related contractual renewal period for the pool of renewal contracts. The Company determines the period of benefit for commissions paid for contracts with new customers and incremental sales to existing customers by taking into consideration its initial estimated customer life and the technological life of its software and related significant features. Commissions paid on professional services are typically amortized in accordance with the associated revenue as the commissions paid on new and renewal professional services are commensurate with each other. 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. |
| Cost of Revenue | Cost of Revenue Cost of revenue consists primarily of costs related to providing subscription and professional services to the Company’s customers, including personnel costs (salaries, bonuses and benefits, and stock-based compensation) and related expenses for customer support and services personnel, as well as cloud infrastructure costs, third-party expenses, depreciation of fixed assets, amortization associated with acquired intangible assets, and allocated overhead. |
| Research and Development | Research and Development Research and development costs are expensed as incurred and consist primarily of personnel costs, including salaries, bonuses and benefits, and stock-based compensation. Research and development costs also include depreciation and allocated overhead. |
| Advertising | Advertising Advertising costs are charged to operations as incurred or the first time the advertising takes place, based on the nature of the advertising, and include direct marketing, events, public relations, sales collateral materials and partner programs. Advertising costs were $16.7 million, $7.7 million and $6.5 million for the years ended April 30, 2021, 2020 and 2019 respectively. Advertising costs are recorded in sales and marketing expense in the consolidated statement of operations. |
| Stock-Based Compensation | Stock-Based Compensation Compensation expense related to stock awards issued to employees, including stock options, restricted stock awards (“RSAs”), and restricted stock units (“RSUs”) is measured at the fair value on the date of the grant and recognized over the requisite service period. The fair value of stock options is estimated on the date of the grant using the Black-Scholes option-pricing model. The fair value of RSAs and RSUs is estimated on the date of the grant based on the fair value of the Company’s underlying ordinary shares. Compensation expense for stock options and RSUs is recognized on a straight-line basis over the requisite service period. Compensation expense for RSAs is amortized on a graded basis over the requisite service period as long as the underlying performance condition is probable to occur. RSAs issued included a performance condition in the form of a specified liquidity event. The liquidity event condition was satisfied upon the effectiveness of the Company’s registration statement on Form S-1 (“IPO registration statement”), on October 4, 2018. On that date, the Company recorded a cumulative stock-based compensation expense of $1.7 million using the accelerated attribution method for all RSAs, for which the service condition had been fully satisfied as of October 4, 2018. The remaining unrecognized stock-based compensation expense |
| Net Loss per Share Attributable to Ordinary Shareholders | Net Loss per Share Attributable to Ordinary Shareholders The Company calculates basic net loss per share by dividing the net loss by the weighted-average number of ordinary shares outstanding during the period, less shares subject to repurchase. Diluted net loss per share is computed by giving effect to all potentially dilutive ordinary share equivalents outstanding for the period, including stock options and restricted stock units. Prior to the completion of the IPO in October 2018, the Company calculated basic and diluted net loss per share attributable to ordinary shareholders in conformity with the two-class method required for companies with participating securities. The Company considered all series of redeemable convertible preference shares and early exercised stock options to be participating securities as the holders were entitled to receive non-cumulative dividends on a pari passu basis in the event that a dividend was paid on ordinary shares. Under the two-class method, the net loss attributable to ordinary shareholders was not allocated to the redeemable convertible preference shares and early exercised stock options as the holders of redeemable convertible preference shares and early exercised stock options did not have a contractual obligation to share in losses. Under the two-class method, basic net loss per share attributable to ordinary shareholders was calculated by dividing the net loss by the weighted-average number of ordinary shares outstanding during the period, less shares subject to repurchase. Diluted net loss per share attributable to ordinary shareholders was computed by giving effect to all potentially dilutive ordinary shares outstanding for the period. For purposes of this calculation, redeemable convertible preference shares, stock options to acquire ordinary shares, contingently issuable shares, and early exercised stock options were considered potentially dilutive ordinary shares, but had been excluded from the calculation of diluted net loss per share attributable to ordinary shareholders as their effect was antidilutive. Upon completion of the IPO, all shares of redeemable convertible preference shares then outstanding were automatically converted into an equivalent number of shares of ordinary shares on a one-to-one basis and their carrying amount reclassified into shareholders’ deficit. As of April 30, 2021, the Company did not have any redeemable convertible preference shares issued and outstanding. |
| Treasury Shares | Treasury Shares Ordinary shares of the Company that are repurchased are recorded as treasury shares at cost and are included as a component of shareholders’ equity. |
| Segments | Segments Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”). The Company’s Chief Executive Officer is its CODM. The Company’s CODM reviews financial information presented on a consolidated basis for the purposes of making operating decisions, allocating resources and evaluating financial performance. As such, the Company has determined that it operates in one operating and one reportable segment. The Company presents financial information about its operating segment and geographical areas in Note 15 to the consolidated financial statements. |
| Income Taxes | Income Taxes The Company is subject to income taxes in the Netherlands and numerous foreign jurisdictions. These foreign jurisdictions may have different statutory rates than the Netherlands. The Company records a provision for income taxes for the anticipated tax consequences of the reported results of operations using the asset and liability method. Under this method, the Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and the tax basis of assets and liabilities, as well as for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. The Company records a valuation allowance to reduce its deferred tax assets to the net amount that it believes is more likely than not to be realized. The calculation of the Company’s tax obligations involves dealing with uncertainties in the application of complex tax laws and regulations. ASC 740, Income Taxes, provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. The Company has assessed its income tax positions and recorded tax benefits for all years subject to examination, based upon the Company’s evaluation of the facts, circumstances and information available at each period end. For those tax positions where the Company has determined there is a greater than fifty percent likelihood that a tax benefit will be sustained, the Company has recorded the largest amount of tax benefit that may potentially be realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is determined there is less than fifty percent likelihood that a tax benefit will be sustained, no tax benefit has been recognized. Although the Company believes that it has adequately reserved for its uncertain tax positions, the Company can provide no assurance that the final tax outcome of these matters will not be materially different. As the Company expands internationally, it will face increased complexity, and the Company’s unrecognized tax benefits may increase in the future. The Company makes adjustments to its reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made. |
| 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 April 30, 2021, the Company had $3.2 million of customer deposits included in accrued expenses and other liabilities. As of April 30, 2020, the Company had $2.6 million of customer deposits included in accrued expenses and other liabilities, and $8.5 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 Credit Losses: In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , and has since issued various amendments including ASU No. 2018-19, ASU No. 2019-4, and ASU No. 2019-5. The standard and related amendments modify the accounting for credit losses for most financial assets and requires an entity to utilize a new impairment model known as current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized costs basis of the financial asset, presents the amount expected to be collected on the financial asset. Additionally, ASU No. 2016-13 amends the current available-for-sale security impairment model for debt securities held for investment. The new model requires an estimate of expected credit losses when the fair value is below the amortized cost of the asset. The credit-related impairment (and subsequent recoveries) are recognized as an allowance on the balance sheet with a corresponding adjustment to the income statement. Non-credit related losses will continue to be recognized through OCI. This guidance also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company adopted ASU No. 2016-13 on May 1, 2020. The Company’s adoption of this ASU resulted in a $0.4 million reduction to accumulated deficit. Goodwill Impairment : In January 2017, the FASB issued ASU No. 2017-4, Intangibles— Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The standard will simplify the measurement of goodwill impairment 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 Company adopted ASU No. 2017-4 on May 1, 2020. The Company's adoption of this ASU did not have a material impact on the Company's consolidated financial statements. Fair Value Measurements : In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) , which modifies, removes and adds certain disclosure requirements on fair value measurements based on the FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements . 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 Company adopted ASU No. 2018-13 on May 1, 2020. The Company's adoption of this ASU did not have a material impact on the Company's consolidated financial statements. Intangible Assets : In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns 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 Company adopted ASU No. 2018-15 on May 1, 2020 and applied it prospectively to implementation costs incurred after the date of adoption. The Company’s adoption of this ASU had no material impact on the Company’s consolidated financial statements. New Accounting Pronouncements Not Yet Adopted Income Taxes: In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , eliminating certain exceptions to the general principles in ASC 740 related to intra-period tax allocation, deferred tax liability and general methodology for calculating income taxes. Additionally, the ASU makes other changes for matters such as franchise taxes that are partially based on income, transactions with a government that result in a step up in the tax basis of goodwill, separate financial statements of legal entities that are not subject to tax, and enacted changes in tax laws in interim periods. The new guidance becomes effective for the Company for the fiscal year ending April 30, 2022. Early adoption is permitted. The Company does not expect the adoption of the new accounting standard to have a material impact on its consolidated financial statements. Equity Awards: In May 2021, the FASB issued ASU No. 2021-4, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options |
| Reclassification | Reclassification In connection with the preparation of the Company’s consolidated financial statements for the year ended April 30, 2021, the Company identified an immaterial misclassification in the prior year balance sheet, which understated short term deferred revenue and overstated long term deferred revenue by $11.6 million as of April 30, 2020. The Company has corrected for this immaterial misclassification in the accompanying consolidated balance sheet by revising the April 30, 2020 deferred revenue balances. This change in classification has no effect on previously reported cash flows in the condensed consolidated statement of cash flows and has no effect on previously reported consolidated statements of operations for any period. |
