Business and Summary of Significant Accounting Policies	12 Months Ended
Business and Summary of Significant Accounting Policies	Jul. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Summary of Significant Accounting Policies	Business and Summary of Significant Accounting Policies Description of the Business Zscaler, Inc. ("Zscaler," the "Company," "we," "us," or "our") is a cloud security company that developed a platform incorporating core security functionalities needed to enable fast and secure access to cloud resources based on identity, context and organization’s policies. Our solution is a purpose-built, multi-tenant, distributed cloud platform that incorporates the security functionality needed to enable users, applications, and devices to safely and efficiently utilize authorized applications and services based on an organization’s business policies. We deliver our solutions using a software-as-a-service ("SaaS") business model and sell subscriptions to customers to access our cloud platform, together with related support services. We were incorporated in Delaware in September 2007 and conduct business worldwide, with presence in North America, Europe and Asia. Our headquarters are in San Jose, California. Fiscal Year Our fiscal year ends on July 31. References to fiscal 2022, for example, refer to our fiscal year ended July 31, 2022. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries and have been prepared in conformity with generally accepted accounting principles in the United States ("GAAP"). All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of revenue recognition, deferred revenue, deferred contract acquisition costs, capitalized internal-use software development costs, valuation of acquired intangible assets, period of benefit generated from our deferred contract acquisition costs, allowance for doubtful accounts, valuation of common stock options and stock-based awards, useful lives of property and equipment, useful lives of acquired intangible assets, recoverability of goodwill, valuation of deferred tax assets and liabilities, loss contingencies related to litigation, fair value and effective interest rate of convertible senior notes and the discount rate used for operating leases. Management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Actual results could differ significantly from these estimates, and such differences may be material to the consolidated financial statements. Due to uncertainty in the macroeconomic environment, including effects of COVID-19 and inflation, there is ongoing disruption in the global economy and financial markets. We are not aware of any specific event or circumstances that would require an update to our estimates, judgments or assumptions or a revision to the carrying value of our assets or liabilities as of the date of issuance of these consolidated financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained. Foreign Currency The functional currency of our foreign subsidiaries is the U.S. dollar. Accordingly, monetary assets and liabilities of our foreign subsidiaries are re-measured into U.S. dollars at the exchange rates in effect at the reporting date, non-monetary assets and liabilities are re-measured at historical rates, revenue and expenses are re-measured at average exchange rates in effect during each reporting period. Foreign currency transaction gains and losses are recorded in other income (expense), net in the consolidated statements of operations. Foreign currency remeasurement gains and losses and foreign currency transaction gains and losses are not significant to the consolidated financial statements. Concentration of Risks We generate revenue primarily from sale of subscriptions to access our cloud platform, together with related support services. Our sales team, along with our channel partner network of global telecommunications service providers, system integrators and value-added resellers (collectively "channel partners"), sells our services worldwide to organizations of all sizes. Due to the nature of our services and the terms and conditions of our contracts with our channel partners, our business could be affected unfavorably if we are not able to continue our relationships with them. Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments and accounts receivable. Although we deposit our cash with multiple financial institutions, the deposits, at times, may exceed federally insured limits. Cash equivalents and short-term investments consist of highly liquid investments in money market funds, U.S. treasury, U.S. agency securities and corporate debt securities, which are invested through financial institutions in the United States. We grant credit to our customers in the normal course of business. We monitor the financial condition of our customers to reduce credit risk. Refer to Note 2, Revenue Recognition, for information regarding customers with concentration of 10% or more of the total balance of accounts receivable, net. Segment Information We operate as one reportable and operating segment. Our chief operating decision maker is our chief executive officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources. Revenue Recognition In accordance with Accounting Standards Codification ("ASC") Topic 606, Revenue From Contracts With Customers ("ASC 606"), revenue is recognized when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration that we expect to be entitled to receive in exchange for these services. To achieve the core principle of this standard, we apply the following five steps: 1) Identify the contract with a customer We consider the terms and conditions of the contracts and our customary business practices in identifying our contracts under ASC 606. We determine we have a contract with a customer when the contract is approved, we can identify each party’s rights regarding the services to be transferred, we can identify the payment terms for the services, we have determined the customer has the ability and intent to pay and the contract has commercial substance. We apply 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 and financial information pertaining to the customer. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the service either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the services is separately identifiable from other promises in the contract. Our performance obligations consist of (i) our subscription and support services and (ii) professional and other services. 3) Determine the transaction price The transaction price is determined based on the consideration to which we expect to be entitled in exchange for transferring services to the customer. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of our contracts contain a significant financing component. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price ("SSP"). 5) Recognize revenue when or as we satisfy a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised service to a customer. Revenue is recognized when control of the services is transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those services. We generate all our revenue from contracts with customers and apply judgment in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition. Subscription and Support Revenue We generate revenue primarily from sales of subscriptions to access our cloud platform, together with related support services to our customers. Arrangements with customers do not provide the customer with the right to take possession of our software operating our cloud platform at any time. Instead, customers are granted continuous access to our cloud platform over the contractual period. A time-elapsed output method is used to measure progress because we transfer control evenly over the contractual period. Accordingly, the fixed consideration related to subscription and support revenue is generally recognized on a straight-line basis over the contract term beginning on the date that our service is made available to the customer. The typical subscription and support term is one to three years. Most of our contracts are non-cancelable over the contractual term. Customers typically have the right to terminate their contracts for cause if we fail to perform in accordance with the contractual terms. Some of our customers have the option to purchase additional subscription and support services at a stated price. These options generally do not provide a material right as they are priced at our SSP. Professional and Other Services Revenue Professional and other services revenue consists of fees associated with providing deployment advisory services that educate and assist our customers on the best use of our solutions, as well as advise customers on best practices as they deploy our solution. These services are distinct from subscription and support services. Professional services do not result in significant customization of the subscription service. Revenue from professional services provided on a time and materials basis is recognized as the services are performed. Total professional and other services revenue has historically not been material. Contracts with Multiple Performance Obligations Most of our contracts with customers contain multiple promised services consisting of: (i) our subscription and support services and (ii) professional and other services that are distinct and accounted for separately. The transaction price is allocated to the separate performance obligations on a relative SSP basis. We determine SSP based on our overall pricing objectives, taking into consideration the type of subscription and support services and professional and other services, the geographical region of the customer and the number of users. Variable Consideration Revenue from sales is recorded at the net sales price, which is the transaction price, and includes estimates of variable consideration. The amount of variable consideration that is included in the transaction price is constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue will not occur when the uncertainty is resolved. If our services do not meet certain service level commitments, our customers are entitled to receive service credits, and in certain cases, refunds, each representing a form of variable consideration. We have historically not experienced any significant incidents affecting the defined levels of reliability and performance as required by our subscription contracts. Accordingly, estimated refunds related to these agreements were not material to the periods presented. We provide rebates and other credits within our contracts with certain customers, which are estimated based on the value expected to be earned or claimed on the related sales transaction. Overall, the transaction price is reduced to reflect our estimate of the amount of consideration to which we are entitled based on the terms of the contract. Estimated rebates and other credits were not material during the periods presented. Accounts Receivable and Allowance Accounts receivable are recorded at the invoiced amount and are non-interest bearing. Accounts receivable are stated at their net realizable value, net of an allowance for doubtful accounts. We have a well-established collections history from our customers. Credit is extended to customers based on an evaluation of their financial condition and other factors. In determining the necessary allowance for doubtful accounts, we estimate the lifetime expected credit losses against the existing accounts receivable balance. Our estimate is based on certain factors including historical loss rates, current economic conditions, reasonable and supportable forecasts and customer-specific circumstances. The allowance for doubtful accounts has historically not been material. There were no material write-offs recognized in the periods presented. Accordingly, the movements in the allowance for doubtful accounts were not material for any of the periods presented. We do not have any off-balance-sheet credit exposure related to our customers. Cash Equivalents and Short-Term Investments We classify all highly liquid investments purchased with an original maturity of 90 days or less from the date of purchase as cash equivalents and all highly liquid investments with original maturities beyond 90 days at the time of purchase as short-term investments. Our cash equivalents and short-term investments consist of highly liquid investments in money market funds, U.S. treasury securities, U.S. government agency securities and corporate debt securities. We classify our investments as available-for-sale investments and present them within current assets since these investments represent funds available for current operations and we have the ability and intent, if necessary, to liquidate any of these investments in order to meet our liquidity needs or to grow our business, including for potential business acquisitions or other strategic transactions. Our investments are carried at fair value, with unrealized gains and losses unrelated to credit loss factors reported in accumulated other comprehensive income (loss) ("AOCI"). Our investments are reviewed periodically when there is a decline in a security’s fair value below the amortized cost basis. We consider our intent to sell and whether it is more likely than not that we will be required to sell the securities before the recovery of its cost basis. If either of these criteria are triggered, the amortized cost basis of the debt security is written down to fair value through other income (expense), net. If neither criteria is met, we evaluate whether the decline in fair value below the amortized cost basis is related to credit-related factors or other factors such as interest rate fluctuations. The factors considered in this analysis include the extent the fair value is less than the amortized cost basis, whether there were changes to the rating of the security by a ratings agency, whether the issuer has failed to make scheduled interest payments and other adverse conditions as applicable. Credit-related impairment losses, limited by the amount that the fair value is less than the amortized cost basis, are recorded through an allowance for credit losses in other income (expense), net. For purposes of identifying and measuring credit-related impairments, our policy is to exclude the applicable accrued interest from both the fair value and amortized cost basis of the related debt security. Accrued interest receivable, net of the allowance for credit losses, if any, is recorded to prepaid expenses and other current assets. There were no credit-related impairments recognized on our investments during the periods presented. Interest income, amortization (accretion) of investments purchased at a premium (discount) and realized gains and losses are included in interest income in the consolidated statements of operations. We use the specific identification method to determine the cost in calculating realized gains and losses upon the sale of these investments. Strategic Investments Our strategic investments consist of non-marketable equity investments of privately held companies. Investments in non-marketable equity investments of privately held companies without readily determinable fair values are measured using the measurement alternative, as we have less than 20% ownership and do not have the ability to exercise significant influence over their operations. The carrying amount of non-marketable equity investments is adjusted based on observable price changes from orderly transactions for identical or similar investments of the same issuer and by impairments, when events or circumstances indicate a decline in value has occurred. Non-marketable equity investments that have been remeasured during the period due to an observable event or impairment are classified within Level 3 in the fair value hierarchy because we estimate the value based on valuation methods which may include a combination of the observable transaction price at the transaction date and other unobservable inputs including volatility, rights, and obligations of the investments we hold. Our strategic investments are included within other noncurrent assets in the consolidated balance sheets and adjustments to their carrying amounts are recorded in other income (expense), net in the consolidated statements of operations. There were no material events or circumstances impacting the carrying amount of our strategic investments during the periods presented. Fair Value of Financial Instruments Our financial instruments consist of cash equivalents, short-term investments, accounts receivable, accounts payable, accrued liabilities and convertible senior notes. Cash equivalents and short-term investments are recorded at fair value. 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 recorded at fair value on a recurring basis in the consolidated balance sheets, consisting of cash equivalents and short-term investments, are categorized in accordance with the fair value hierarchy based upon the level of judgment associated with the inputs used to measure their fair values. Convertible senior notes are carried at the initially allocated liability value less unamortized debt discount and issuance costs on the consolidated balance sheets, and the fair value of the convertible senior notes is presented at each reporting period for disclosure purposes only. Property and Equipment Property and equipment, net are stated at historical cost net of accumulated depreciation. Property and equipment, excluding leasehold improvements, are depreciated using the straight-line method over the estimated useful lives of the respective assets, generally ranging from three to five years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the respective assets or the lease term. Expenditures for maintenance and repairs are expensed as incurred and significant improvements and betterments that substantially enhance the life of an asset are capitalized. Capitalized Internal-Use Software Development Costs We capitalize certain costs incurred during the application development stage in connection with software development for our cloud security platform. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Capitalized costs are recorded as part of property and equipment in the consolidated balance sheets. Maintenance and training costs are expensed as incurred. Capitalized internal-use software is amortized on a straight-line basis over its estimated useful life, which is generally three years, and is recorded as cost of revenue in the consolidated statements of operations. Capitalization of development costs, inclusive of stock-based compensation, of software for internal-use in fiscal 2022, fiscal 2021 and fiscal 2020 was $32.7 million, $16.5 million and $13.2 million, respectively. Amortization expense of capitalized software for internal-use in fiscal 2022, fiscal 2021 and fiscal 2020 was $13.0 million, $5.9 million and $1.4 million, respectively. Business Combinations We account for our business combinations using the acquisition method of accounting, which requires, among other things, allocation of the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed at their estimated fair values on the acquisition date. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, we make estimates and assumptions, especially with respect to intangible assets. Our estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, we may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill if new information is obtained related to facts and circumstances that existed as of the acquisition date. After the measurement period, any subsequent adjustments are reflected in the consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred. Goodwill and Other Long-Lived Assets, including Acquired Intangible Assets Goodwill represents the excess of the fair value of purchase consideration in a business combination over the fair value of net tangible and intangible assets acquired. Goodwill amounts are not amortized, but rather tested for impairment at least annually or more often if circumstances indicate that the carrying value may not be recoverable. There was no impairment of goodwill during any of the periods presented. Acquired intangible assets consist of identifiable intangible assets, including developed technology and customer relationships, resulting from business combinations. Acquired finite-lived intangible assets are initially recorded at fair value and are amortized on a straight-line basis over their estimated useful lives. Amortization expense of developed technology and customer relationships is recorded primarily within cost of revenues and sales and marketing expenses, respectively, in the consolidated statements of operations. Long-lived assets, such as property and equipment and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. We measure the recoverability of these assets by comparing the carrying amounts to the future undiscounted cash flows that these assets are expected to generate. If the total of the future undiscounted cash flows are less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the asset exceeds the fair value. In fiscal 2022, there were no asset impairments. In fiscal 2021, we recognized asset impairments of $0.4 million in general and administrative expenses in the consolidated statement of operations related primarily to the abandonment of a leased facility and relocation of our corporate headquarters. Derivative Instruments We enter into foreign currency forward contracts, a portion of which we designate as cash flow hedges, in order to manage the volatility of cash flows that relate to our cost of revenues and operating expenses denominated in foreign currencies. Gains or losses related to our cash flow hedges are recorded as a component of AOCI on the consolidated statements of stockholders' equity until the forecasted transaction occurs in earnings. When the forecasted transaction occurs, the related gains and losses are reclassified into earnings within the financial statement line item associated with the underlying hedged transaction. If the underlying hedged transaction does not occur, or it becomes probable that the hedged transaction will not occur, the cumulative unrealized gain or loss is reclassified immediately from AOCI into earnings within the financial statement line item associated with the underlying hedged transaction. We measure hedge effectiveness using regression analysis at hedge inception and periodically thereafter. We include time value in our effectiveness assessment. We recognize changes in the fair value of non-designated derivative instruments within other income (expense), net in the consolidated statements of operations in the same period that the fair value measurement occurs. All of our derivative instruments are measured at fair value. We have elected to present the derivative assets and derivative liabilities on a gross basis on the consolidated balance sheets. Derivative instruments are classified in the consolidated statements of cash flows as cash from operating activities, which reflect the classification of the underlying hedged transactions. Operating Leases We enter into operating lease arrangements for real estate assets related to office space and co-location assets related to space and racks at data center facilities. We determine if an arrangement contains a lease at its inception by assessing whether there is an identified asset and whether the arrangement conveys the right to control the use of the identified asset in exchange for consideration. Operating leases related balances are included in "operating lease right-of-use assets," "operating lease liabilities," and "operating lease liabilities, noncurrent" in the consolidated balance sheets. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make payments arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments consist of the fixed payments under the arrangement. The operating lease liabilities are adjusted for any unpaid lease incentives, such as tenant improvement allowances. Variable costs, such as maintenance and utilities based on actual usage, are not included in the measurement of right-to-use assets and lease liabilities but are expensed when the event determining the amount of variable consideration to be paid occurs. As the implicit rate of our leases is not determinable, we use an incremental borrowing rate ("IBR") based on the information available at the lease commencement date in determining the present value of lease payments. The lease expense is recognized on a straight-line basis over the lease term. We generally use the base, non-cancelable lease term when recognizing the right-of-use assets and lease liabilities, unless it is reasonably certain that a renewal or termination option will be exercised. We account for lease components and non-lease components as a single lease component. Leases with a term of twelve months or less are not recognized on the consolidated balance sheets. We recognize lease expense for these leases on a straight-line basis over the term of the lease. Stock-Based Compensation Compensation expense related to stock-based awards granted to employees and non-employees is calculated based on the fair value of stock-based awards on the date of grant. We recognize stock-based compensation expense over an award’s requisite service period based on the award’s fair value. Stock-based compensation for common stock options is recognized based on the fair value of the awards granted, determined using the Black-Scholes option pricing model. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period, generally four years. Stock-based compensation for purchase rights granted under the employee stock purchase plan is based on the fair value of the number of awards estimated at the beginning of the offering period, as determined using the Black-Scholes option pricing model. Stock-based compensation expense is recognized following the straight-line attribution method over the offering period. Stock-based compensation for restricted stock units is measured based on the market closing price of our common stock on the grant date. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period, generally four years. Stock-based compensation for performance stock awards (“PSAs”), which have the same grant date and service inception date, is based on the probable number of shares to be attained and the market closing price of our common stock at the grant date. For PSAs where the service inception date of the awards precedes the grant date, stock-based compensation expense is recognized based on the number of PSAs for which it is probable that the performance condition will be met, using the accelerated attribution method and the market closing price of our common stock at each reporting date up to the grant date. The number of these PSAs for which it is probable that the performance condition will be met is determined using management’s best estimate at the end of each reporting period. At the completion of the performance period for these PSAs, any earned PSAs are granted upon approval of the compensation committee of our board of directors. Convertible Senior Notes In accounting for the issuance of the convertible senior notes, we separated the convertible senior notes into liability and equity components. The carrying amounts of the liability component was calculated by measuring the fair value of similar liabilities that do not have associated convertible features. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the convertible senior notes as a whole. This difference represents the debt discount that is amortized to interest expense over the respective terms of the convertible senior notes using the effective interest rate method. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the related debt issuance costs, we allocated the total amount incurred to the liability and equity components of the convertible senior notes based on their relative values. Issuance costs attributable to the liability component are being amortized to interest expense over the contractual term of the convertible senior notes. The issuance costs attributable to the equity component were netted against the equity component representing the conversion option in additional paid-in capital. To the extent that we receive the convertible senior notes conversion requests prior to their maturity, a portion of the equity component is classified as temporary equity, which is measured as the difference between the principal and net carrying amount of the convertible senior notes requested for conversion. Upon settlement of the conversion requests, the difference between the fair value and the amortized book value of the liability component of the convertible senior notes requested for conversion is recorded as a gain or loss on early note conversion. The fair value of the convertible senior notes is measured based on a similar liability that does not have an associated convertible feature based on the remaining term of the convertible senior notes. Research and Development Our research and development expenses support our efforts to add new features to our existing offerings and to ensure the reliability, availability and scalability of our solutions. Our cloud platform is software-driven, and our research and development teams employ software engineers in the design and the related development, testing, certification and support of our solutions. Accordingly, the majority of our research and development expenses result from employee-related costs, including salaries, bonuses, benefits, stock-based compensation and costs associated with technology tools used by our engineers. Advertising Expenses Advertising expenses are charged to sales and marketing expenses in the consolidated statements of operations as incurred. We recognized advertising expense of $22.1 million, $11.8 million and $11.8 million in fiscal 2022, fiscal 2021 and fiscal 2020, respectively. Warranties and Indemnification Our cloud platform is generally warranted to be free of defects under normal use and to perform substantially in accordance with the subscription agreement. Additionally, our contracts generally include provisions for indemnifying customers and channel partners against liabilities if our services infringe or misappropriate a third party’s intellectual property rights. Costs and liabilities incurred as a result of warranties and indemnification obligations were not material during the periods presented. Legal Contingencies We may be subject to legal proceedings and litigation arising from time to time. We record a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. We periodically evaluate developments in our legal matters that could affect the amount of liability that we accrue, if any, and adjust, as appropriate. Until the final resolution of any such matter for which we may be required to record a liability, there may be a loss exposure in excess of the liability recorded and such amount could be significant. We expense legal fees as incurred. Income Taxes We account for income taxes using the asset and liability method. Deferred income taxes are recognized by applying the enacted statutory tax rates applicable to future years to differences between the carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and tax credit carryforwards. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance to amounts that are more likely than not to be realized. We recognize tax benefits from uncertain tax positions only if we believe that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Comprehensive Loss Comprehensive loss is comprised of the net loss and other comprehensive income (loss). Our other comprehensive income (loss) includes unrealized gains and losses on available-for-sale securities and unrealized gains and losses and realized gains and losses reclassified into net loss on cash flow hedges, as reflected in the consolidated statements of comprehensive loss. Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted earnings per share adjusts basic earnings per share for all potentially dilutive common stock equivalents outstanding during the period. Potentially dilutive securities consist primarily of stock options, shares subject to repurchase from early exercised stock options, share purchase rights under the employee stock purchase plan, unvested restricted stock units ("RSUs"), unvested performance stock awards ("PSAs"), unvested common stock and shares related to convertible senior notes. Since we have reported net losses for all periods presented, we have excluded all potentially dilutive securities from the calculation of the diluted net loss per share, as their effect is antidilutive. Accordingly, basic and diluted net loss per share is the same for all periods presented. Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU No. 2019-12, Income Taxes (Topic 740) ("ASU 2019-12"): Simplifying the Accounting for Income Taxes. The new standard eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences related to changes in ownership of equity method investments and foreign subsidiaries. The guidance also simplifies aspects of accounting for franchise taxes and enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. For public business entities, it is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. We early adopted this standard in the second quarter of fiscal 2020 and it did not have a material impact to the consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities to require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of operations. We adopted this standard in the first quarter of fiscal 2021 and it did not have a material impact to the consolidated financial statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805) on Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This standard requires contract assets and contract liabilities from contracts with customers that are acquired in a business combination to be recognized and measured as if the acquirer had originated the original contract. Previously, acquired contract assets and liabilities were measured at fair value. This standard is effective for us in the first quarter of fiscal 2024, though early adoption is permitted. We early adopted this standard in the first quarter of fiscal 2022 and it did not have a material impact to the consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) ("ASU 2020-06"). This standard removes the separation model for convertible debt with a cash conversion feature and convertible instruments with a beneficial conversion feature. Such convertible debt will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. We adopted this standard effective on August 1, 2022, the beginning of fiscal 2023, using the modified retrospective method. This standard will result in our convertible senior notes being accounted for as a single unit of debt and we will no longer be required to record the conversion feature in equity. This will further eliminate the need for amortization of the debt discount as interest expense and the portion of the issuance costs initially allocated to equity will be classified to debt and amortized as interest expense. As of August 1, 2022, the adoption of this new standard resulted in an increase of $169.9 million to the carrying amount of the convertible senior notes, a decrease of $273.7 million to additional paid-in capital and a cumulative-effect adjustment of $103.8 million to accumulated deficit.

Significant Customers

No single customer accounted for 10% or more of the total revenue or the total balance of accounts receivable, net in the periods presented.

Contract Balances

Contract liabilities consist of deferred revenue and include payments received in advance of performance under the contract. Such amounts are recognized as revenue over the contractual period. Deferred revenue, including current and noncurrent balances as of July 31, 2022 and July 31, 2021 was $1,021.1 million and $630.6 million, respectively. In fiscal 2022, fiscal 2021 and fiscal 2020 we recognized revenue of $570.3 million, $335.5 million and $220.9 million, respectively, that was included in the corresponding contract liability balance at the beginning of the related fiscal year.

We receive payments from customers based upon contractual billing schedules and accounts receivable are recorded when the right to consideration becomes unconditional. Payment terms on invoiced amounts are typically 30 days but may be up to 90 days for some of our channel partners. Contract assets include amounts related to our contractual right to consideration for both completed and partially completed performance obligations that may not have been invoiced and such amounts have historically not been material.

Remaining Performance Obligations

The typical subscription and support term is one to three years. Most of our subscription and support contracts are non-cancelable over the contractual term. However, customers typically have the right to terminate their contracts for cause, if we fail to perform. As of July 31, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was $2,607.2 million. We expect to recognize 49% of the transaction price over the next 12 months and 96% of the transaction price over the next three years, with the remainder recognized thereafter.

Costs to Obtain and Fulfill a Contract

We capitalize sales commission and associated payroll taxes paid to internal sales personnel that are incremental to the acquisition of channel partner and direct customer contracts. These costs are recorded as deferred contract acquisition costs in the consolidated balance sheets. We determine whether costs should be deferred based on our sales compensation plans, if the commissions are in fact incremental and would not have occurred absent the customer contract.

Sales commissions for renewal of a contract are not considered commensurate with the commissions paid for the acquisition of the initial contract given the substantive difference in commission rates in proportion to their respective contract values. 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 over the contractual term of the renewals. Amortization of deferred contract acquisition costs is recognized on a straight-line basis commensurate with the pattern of revenue recognition and included in sales and marketing expense in the consolidated statements of operations.

We determine the period of benefit for commissions paid for the acquisition of the initial contract by taking into consideration the expected subscription term and expected renewals of our customer contracts, the duration of our relationships with our customers, customer retention data, our technology development lifecycle and other factors. We periodically review 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. We did not recognize any impairment losses of deferred contract acquisition costs during the periods presented.

The activity of the deferred contract acquisition costs consisted of the following:


	Year Ended July 31,
	2022		2021		2020

	(in thousands)
Beginning balance	$	207,030	$	109,915	$	69,785
Capitalization of contract acquisition costs	158,503		137,673		65,052
Amortization of deferred contract acquisition costs	(68,531)		(40,558)		(24,922)
Ending balance	$	297,002	$	207,030	$	109,915

The outstanding balance of the deferred contract acquisition costs consisted of the following:


	July 31,
	2022		2021

	(in thousands)
Deferred contract acquisition costs	$	86,210	$	57,373
Deferred contract acquisition costs, noncurrent	210,792		149,657
Total deferred contract acquisition costs	$	297,002	$	207,030

Sales commissions accrued but not paid as of July 31, 2022 and 2021, totaled $47.2 million and $46.7 million, respectively, which are included within accrued compensation in the consolidated balance sheets.

We review the individual securities that have unrealized losses in our short-term investment portfolio on a regular basis. We evaluate, among others, whether we have the intention to sell any of these investments and whether it is not more likely than not that we will be required to sell any of them before recovery of the amortized cost basis. Neither of these criteria were met in any period presented. We additionally evaluate whether the decline in fair value of the corporate debt securities below its amortized cost basis is related to credit losses or other factors. Based on this evaluation, we determined that unrealized losses of the above securities were primarily attributable to changes in interest rates and non credit-related factors. Accordingly, we determined that an allowance for credit losses was unnecessary for our short-term investments as of July 31, 2022 and 2021.

We recorded $1.3 million and $3.9 million of accrued interest receivable within prepaid expenses and other current assets in the consolidated balance sheets as of July 31, 2022 and 2021, respectively.

Strategic Investments

Our strategic investments consist primarily of non-marketable equity securities of privately held companies which do not have a readily determinable fair value. These investments are primarily accounted for under the cost method as we have less than 20% ownership and do not have the ability to exercise significant influence over their operations. The carrying amount

of our strategic investments was $5.1 million as of July 31, 2022 and 2021, and is included within other noncurrent assets in the consolidated balance sheets. There were no material events or circumstances impacting the carrying amount of our strategic investments during the periods presented.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair value is defined as the exchange price that would be received from sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize 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. Three levels of inputs may be used to measure fair value:

•Level I - Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities;

•Level II - Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments; and

•Level III - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs are based on our own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation.

Our money market funds are classified within Level I due to the highly liquid nature of these assets and have quoted prices in active markets. Certain of our investments in available-for-sale securities (i.e., U.S. treasury securities, U.S. government agency securities and corporate debt securities), as well as our assets and liabilities arising from our foreign currency forward contracts, are classified within Level II. The fair value of our Level II financial assets and liabilities is determined by using inputs based on non-binding market consensus prices that are primarily corroborated by observable market data or quoted market prices for similar instruments, for substantially the full term of the financial assets and liabilities.

Assets and liabilities that are measured at fair value on a recurring basis consisted of the following as of July 31, 2022:


			Level I		Level II		Level III

Business Combination and Asset Acquisition [Abstract]

Business Combinations

ShiftRight, Inc.

On June 17, 2022, we completed the acquisition of ShiftRight, Inc. (“ShiftRight”), an early-stage technology company incorporated in the United States. We plan to integrate this company’s technology into our cloud platform. Pursuant to the terms of the purchase agreement, the aggregate purchase price was approximately $25.6 million in cash. Additionally, certain of ShiftRight's employees who became our employees are entitled to receive deferred merger consideration payable in the form of shares of our authorized common stock and restricted stock units. These awards are subject to time-based vesting and will be recognized as stock-based compensation expense during the post-combination period. In connection with this acquisition, we completed a valuation of the acquired intangible assets as of June 17, 2022. The purchase price allocation resulted in the recognition of $18.7 million of goodwill and $7.1 million of developed technology. The developed technology was valued using a replacement cost approach, which is based on the cost of a market participant to reconstruct a substitute asset of comparable utility. Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired and is primarily attributable to the acquired workforce and expected operating synergies. Goodwill is not expected to be deductible for income tax purposes. We incurred approximately $0.7 million of acquisition related costs, which were recorded as general and administrative expenses in fiscal 2022.

The acquisition qualified as a stock transaction for tax purposes. As a result, we recognized a deferred tax liability of approximately $0.7 million, generated primarily from the difference between the tax basis and fair value of the acquired developed technology, which increased goodwill by the same amount. As we had a full valuation allowance as of July 31, 2022, we recorded an income tax benefit for the same amount as a result of the reduction of the valuation allowance due to establishment of the deferred tax liability in the consolidated statement of operations in fiscal 2022.

The allocation of the purchase price consideration consisted of the following:

Smokescreen Technologies Private Limited

On June 1, 2021, we completed the acquisition of Smokescreen Technologies Private Limited (“Smokescreen”), a technology company incorporated in India. Smokescreen developed an active defense and deception technology, which has been integrated into our cloud platform, further building upon our ability to detect sophisticated, highly targeted attacks, ransomware and lateral movement attempts.

Pursuant to the terms of the stock purchase agreement, the aggregate purchase price was approximately $11.7 million in cash. In connection with this acquisition, we completed a valuation of the acquired intangible assets as of June 1, 2021, in order to allocate the purchase price consideration. The purchase price allocation resulted in the recognition of $5.7 million of goodwill, $5.6 million of developed technology and $2.1 million of customer relationships. The developed technology was valued using a replacement cost approach, which is based on the cost of a market participant to reconstruct a substitute asset of comparable utility. The customer relationships were also valued using the replacement cost approach, which is based on the cost a market participant would incur to generate the acquired portfolio of customers. Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired and is primarily attributable to the acquired workforce and expected operating synergies. Both goodwill and acquired intangible assets will be fully deductible for income tax purposes. We incurred approximately $0.5 million of acquisition related costs, which were recorded as general and administrative expenses in fiscal 2021.

The acquisition qualified as a stock transaction for tax purposes. As a result, we recognized a deferred tax liability of approximately $1.6 million, generated primarily from the difference between the tax basis and fair value of the acquired developed technology, which increased goodwill by the same amount.

In November 2021, we completed a business acquisition for a total purchase price consideration of $2.1 million, consisting of $0.4 million paid in cash at closing and the issuance of shares of our common stock with an aggregate fair value of $1.7 million at closing. Additionally, certain former employees of the acquired company who became our employees are entitled to receive additional consideration in the form of shares of our common stock subject to future employment services. These awards will be recognized as stock-based compensation expense during the post-combination period. Based on the valuation of the acquired intangible assets, the purchase price allocation resulted in the recognition of $1.6 million of developed technology and $0.8 million of goodwill. The developed technology will be amortized over its economic useful life of five years. Goodwill is not expected to be deductible for income tax purposes.

The acquisition qualified as a stock transaction for tax purposes. As a result, we recognized a deferred tax liability for approximately $0.4 million, generated primarily from the difference between the tax basis and fair value of the acquired developed technology, which increased goodwill by the same amount. As we had a full valuation allowance as of July 31, 2022, we recorded an income tax benefit for the same amount as a result of the reduction of the valuation allowance due to the establishment of the deferred tax liability in the consolidated statement of operations in fiscal 2022.

Pro forma financial information

The pro forma financial information from the above business acquisitions, assuming the acquisition had occurred as of the beginning of the fiscal year prior to the fiscal year of the acquisition, as well as revenue and earnings generated during the current fiscal year, were not material for disclosure purposes.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

We implemented a foreign currency risk management program during the fiscal 2021. As a global business, we are exposed to foreign currency exchange rate risk. Substantially all of our revenue is transacted in U.S. dollars; however, a portion of our cost of revenue and operating expenditures are incurred outside of the United States and are denominated in foreign currencies, making them subject to fluctuations in foreign currency exchange rates. In order to mitigate the impact of foreign currency fluctuations on our future cash flows and earnings, we enter into foreign currency forward contracts, which we designate as cash flow hedges. All cash flow hedges were considered effective during fiscal 2022 and fiscal 2021.

We also use foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. The outstanding non-designated derivative instruments are carried at fair value with the change in fair value recorded in other income (expense), net in the consolidated statement of operations in the same period as the changes in fair value from the remeasurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. These foreign exchange contracts typically have maturities of approximately one to four months. Changes in the fair value of these derivatives were not material for fiscal 2022 and fiscal 2021.

As of July 31, 2022 and July 31, 2021, the total notional amount of our outstanding foreign currency forward contracts was $293.4 million and $118.9 million, respectively, for designated foreign currency forward contracts and $126.4 million and $28.2 million, respectively, for non-designated foreign currency forward contracts. The maximum length of time over which forecasted foreign currency denominated operating expenses are hedged is 18 months. Substantially all of the unrealized gains and losses related to our cash flow hedges are expected to be released into earnings over the next 12 months. Refer to Note 4, Fair Value Measurements, for the fair value of our derivative instruments as reported on the consolidated balance sheet as of July 31, 2022 and July 31, 2021.

During the fiscal 2021, the unrealized gains and losses related to our cash flow hedges that were recognized in AOCI and the gains and losses reclassified into the consolidated statement of operations were not material. During fiscal 2022 and fiscal 2021, changes in the fair value of our non-designated derivative instruments recorded in other income (expense), net within the consolidated statement of operations were not material.

During the fiscal 2022, the loss recognized in AOCI related to our cash flow hedges was $20.1 million.

The following table presents information about losses related to our cash flow hedges reclassified from AOCI into the consolidated statement of operations for fiscal 2022:


	Amount

Classification:
Cost of revenue	$	617
Sales and marketing	520
Research and development	284

Total	$	7,013

Our derivative contracts expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the underlying contracts. We mitigate this credit risk by transacting with major financial institutions with high credit ratings and standards. We periodically assess the creditworthiness of our counterparties to ensure they continue to meet our credit quality requirements. We also enter into master netting arrangements, which permit net settlement of transactions with the same counterparty. The potential impact of these rights of set-off associated with our derivative instruments was not material as of July 31, 2022 and July 31, 2021. We are not required to pledge, and are not entitled to receive, cash collateral related to these derivative instruments. We do not enter into derivative contracts for trading or speculative purposes.

Convertible Senior Notes

Debt Disclosure [Abstract]

Convertible Senior Notes

On June 25, 2020, we issued $1,150.0 million in aggregate principal amount of 0.125% Convertible Senior Notes due 2025 (the “Notes”), including the exercise in full by the initial purchasers of the Notes of their option to purchase an additional $150.0 million principal amount of the Notes. The Notes are unsecured obligations and bear interest at a rate of 0.125% per year and interest is payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2021. The Notes mature on July 1, 2025, unless earlier converted, redeemed or repurchased. The total net proceeds from the offering, after deducting initial purchase discounts and other debt issuance costs, was $1,130.5 million.

The Notes do not contain any financial covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or any of our subsidiaries.

The following table presents details of the Notes:

Initial Conversion Rate per $1,000 Principal

Notes

The Notes are convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding April 1, 2025, only under the following circumstances:

•During any fiscal quarter commencing after the fiscal quarter ending on October 31, 2020 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price of the Notes on each applicable trading day;

•During the five-business day period after any five consecutive trading day period (the “measurement period”) in

which the trading price per $1,000 principal amount of the Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate of the Notes on each such trading day;

•If we call any or all of the Notes for redemption, the Notes called for redemption (or, at our election all Notes) may be submitted for conversion at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or

•upon the occurrence of specified corporate events as set forth within the indenture governing the Notes.

On or after April 1, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert, all or any portion of their Notes at any time, in multiples of $1,000 principal amount, at their option regardless of the foregoing circumstances. Upon conversion, we will satisfy the conversion obligation by paying or delivering, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. It is our current intent to settle the principal amount of the Notes in cash.

During the three months ended July 31, 2022, the conditions allowing holders of the Notes to convert were not met. Since we have the election of repaying the Notes in cash, shares of our common stock, or a combination of both, we have classified the Notes as a noncurrent liability in the consolidated balance sheet as of July 31, 2022 and July 31, 2021. Conversion notices received through fiscal 2022 have not been material. No conversion notices were received in fiscal 2021 and fiscal 2020.

We may not redeem the Notes prior to July 5, 2023. On or after July 5, 2023, and prior to the 21st scheduled trading day immediately preceding the maturity date, we may redeem for cash all or any portion of the Notes, at our option, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Notes. If we redeem less than all the outstanding Notes, and only Notes called for redemption may be converted in connection with such partial redemption, at least $100.0 million aggregate principal amount of Notes must be outstanding and not subject to such partial redemption as of the relevant redemption notice date.

In the event of a corporate event that constitutes a “fundamental change" (as defined in the indenture governing the Notes), holders of the Notes will have the right, at their option to require us to repurchase for cash all or any portion of the Notes upon the occurrence of a fundamental change, at a purchase price equal to 100% of the principal amount of the Notes plus any accrued and unpaid interest, up to but excluding, the date of such repurchase. In addition, following certain corporate events that occur prior to the maturity date, or if we issue a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or notice of redemption, as the case may be.

In accounting for the issuance of the Notes and the related transaction costs, we separated the Notes into liability and equity components. The carrying amount of the liability component was initially calculated by measuring the fair value of similar liabilities that do not have associated convertible features utilizing the interest rate of 5.75%. The carrying amount of the equity component representing the conversion option was $278.5 million and was determined by deducting the fair value of the liability component from the par value of the Notes. This difference represents the debt discount that is amortized to interest expense over the term of the Notes using the effective interest rate method. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification.

Total issuance costs of $19.5 million related to the Notes were allocated between liability, totaling $14.8 million, and equity, totaling $4.7 million, in the same proportion as the allocation of the total proceeds to the liability and equity components. Issuance costs attributable to the liability component are being amortized to interest expense over the term of the Notes. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the contractual term of the Notes at an effective interest rate of 6.03%. The issuance costs attributable to the equity component were netted against additional paid-in capital. The amount recorded for the equity component of the Notes was $273.4 million, net of allocated issuance costs of $4.7 million and deferred tax impact of $0.4 million.

The net carrying amount of the liability component of the Notes consisted of the following:

Amortization of debt issuance costs	2,783		2,621		247
Total	$	56,579	$	53,364	$	5,025

The total fair value of the Notes was $1,418.5 million and $1,931.7 million as of July 31, 2022 and 2021, respectively. The fair value was determined based on the closing trading price per $1,000 of the Notes as of the last day of trading for the period. We consider the fair value of the Notes as of July 31, 2022 and 2021 to be a Level II measurement as they are not actively traded. The fair value of the Notes is primarily affected by the trading price of our common stock and market interest rates.

Capped Calls

In connection with the pricing of the Notes, we entered into capped call transactions with the option counterparties (the "Capped Calls"). The Capped Calls each have an initial strike price of $150.80 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Notes. The Capped Calls have an initial cap price of $246.76 per share, subject to certain adjustments. The Capped Calls are generally expected to reduce potential dilution to our common stock upon any conversion of the Notes and/or offset any cash payments we are required to make in excess of the principal amount of the converted Notes, as the case may be, with such reduction and/or offset subject to a cap. The Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting us, including merger events, tender offers and the announcement of such events. In addition, the Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings and hedging disruptions. For accounting purposes, the Capped Calls are

separate transactions, and not part of the terms of the Notes. As the Capped Calls qualify for a scope exception from derivative accounting for instruments that are both indexed to the issuer's own stock and classified in stockholder's equity in the consolidated balance sheet, the premium of $145.2 million paid for the purchase of the Capped Calls was recorded as a reduction to additional paid-in capital and will not be remeasured. We have not exercised any Capped Call options during any of the periods presented.

Legal Matters

Symantec Litigation

On December 12, 2016 and April 18, 2017, Symantec Corporation ("Symantec") filed two separate complaints in the U.S. District Court for the District of Delaware, alleging that "Zscaler's cloud security platform" infringed multiple U.S. patents held by Symantec (the "Symantec Cases"). The complaints in the Symantec Cases sought compensatory damages, injunctions, enhanced damages and attorney fees. In July and August 2017, the Symantec Cases were transferred to the U.S. District Court for the Northern District of California. On November 4, 2019, Broadcom, Inc. ("Broadcom") announced the completion of its acquisition of certain assets and assumption of certain liabilities of Symantec's enterprise security business, including all rights, titles, and interests in the patents asserted in the Symantec Cases.

On January 12, 2020, we entered into a settlement and patent license agreement with CA, Inc., a Broadcom affiliate, pursuant to which the Symantec Cases were dismissed with prejudice effective as of January 13, 2020. In connection with the settlement, we made a payment of $15.0 million to Broadcom, and Broadcom provided us with patent licenses, a release and a covenant not to sue. We determined that there was no material future economic benefit from the acquired Broadcom license and accordingly, we recorded an expense of $15.0 million within general and administrative expenses in the consolidated statement of operations in fiscal 2020.

Other Litigation and Claims

We are a party to various litigation matters from time to time and subject to claims that arise in the ordinary course of business, including patent, commercial, product liability, employment, class action, whistleblower and other litigation and claims, as well as governmental and other regulatory investigations and proceedings. In addition, third parties may from time to time assert claims against us in the form of letters and other communications. There is no pending or threatened legal proceeding to which we are a party that, in our opinion, is likely to have a material adverse effect on our future financial results or operations; however, the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. The expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change and could adversely affect our results of operations.

Stock-Based Compensation

12 Months Ended

Jul. 31, 2022

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

Equity Incentive Plans

We adopted the Fiscal Year 2018 Equity Incentive Plan (the "2018 Plan") in fiscal 2018 and the 2007 Stock Plan (the "2007 Plan") in fiscal 2008, collectively referred to as the "Plans." Equity incentive awards which may be granted to eligible participants under the Plans include restricted stock units, restricted stock, stock options, nonstatutory stock options, stock appreciation rights, performance units and performance shares. With the establishment of the 2018 Plan, we no longer grant stock-based awards under the 2007 Plan and any shares underlying stock options that expire or terminate or are forfeited or repurchased by us under the 2007 Plan are automatically transferred to the 2018 Plan.

As of July 31, 2022, a total of 38.6 million shares of common stock have been reserved for the issuance of equity awards under the 2018 Plan, of which 26.1 million shares were available for grant. The number of shares of common stock available

for issuance under the 2018 Plan also includes an annual increase on the first day of each fiscal year pursuant to its automatic annual increase provision.

Stock Options

The stock option activity consisted of the following for fiscal 2022:


		Outstanding Stock Options	Weighted-Average Exercise Price	Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value

	(in thousands, except per share amounts)
Balance as of July 31, 2021		2,597	$10.37	3.2	$	585,829
Exercised		(905)	$7.68		$	230,068
Canceled, forfeited or expired		(19)	$10.70
Balance as of July 31, 2022		1,673	$11.81	2.5	$	240,286
Exercisable and expected to vest as of July 31, 2021		1,777	$8.53	2.9	$	404,151
Exercisable and expected to vest as of July 31, 2022		1,501	$10.78	2.4	$	216,539

The aggregate intrinsic value of the options exercised represents the difference between the fair value of our common stock on the date of exercise and their exercise price. The total intrinsic value of options exercised for fiscal 2022, fiscal 2021 and fiscal 2020 was $230.1 million, $421.8 million and $242.4 million, respectively. The weighted-average grant-date fair value per share of awards granted for fiscal 2020 was $22.76.

We estimated the fair value of stock options using the Black-Scholes option pricing model with the following assumptions:


									Year Ended July 31(1)
									2020
Expected term (in years)									6.1
Expected stock price volatility									46.1%
Risk-free interest rate									1.7%
Dividend yield									0.0%

(1) There were no stock options granted during fiscal 2022 and fiscal 2021.

Restricted Stock Units and Performance Stock Awards

The 2018 Plan allows for the grant of RSUs. Generally, RSUs are subject to a four-year vesting period, with 25% of the shares vesting approximately one year from the vesting commencing date and quarterly thereafter over the remaining vesting term.

The 2018 Plan allows for the grant of PSAs. The right to earn the PSAs is subject to achievement of the defined performance metrics and continuous employment service. The performance metrics are defined and approved by the compensation committee of our board of directors or by our senior management for certain types of awards. Generally, earned PSAs are subject to additional time-based vesting.

As of July 31, 2022, there were 0.1 million outstanding PSAs for which the performance metrics have not been defined as of such date. Accordingly, such awards are not considered granted for accounting purposes as of July 31, 2022 and have been excluded from the below table.

The activity of RSUs and PSAs consisted of the following for fiscal 2022:


	Underlying Shares	Weighted-Average Grant Date Fair Value	Aggregate Intrinsic Value

	(in thousands, except per share data)
Balance as of July 31, 2021	7,763	$100.84	$	1,831,376
Granted	3,260	$233.92
Vested	(2,994)	$101.59	$	694,853
Canceled or forfeited	(641)	$124.79
Balance as of July 31, 2022	7,388	$157.17	$	1,145,526

Employee Stock Purchase Plan

We adopted the Fiscal Year 2018 Employee Stock Purchase Plan (the "ESPP") in the third quarter of fiscal 2018. As of July 31, 2022, a total of 7.4 million shares of common stock have been reserved for issuance under the ESPP, out of which 3.9 million shares were available for grant. The number of shares reserved includes an annual increase on the first day of each fiscal year pursuant to its automatic annual increase provision. The ESPP provides for consecutive offering periods that will typically have a duration of approximately 24 months in length and is comprised of four purchase periods of approximately six months in length. The offering periods are scheduled to start on the first trading day on or after June 15 and December 15 of each year. During fiscal 2022, fiscal 2021 and fiscal 2020, employees purchased approximately 0.3 million, 0.3 million and 0.8 million shares of common stock, respectively, under the ESPP at an average purchase price of $108.61, $75.92 and $18.76, respectively, with proceeds of $34.6 million, $25.7 million and $15.3 million, respectively.

ESPP employee payroll contributions accrued as of July 31, 2022 and 2021, was $4.7 million and $5.2 million, respectively, and are included within accrued compensation in the consolidated balance sheets. Payroll contributions accrued as of July 31, 2022 will be used to purchase shares at the end of the current ESPP purchase period ending on December 15, 2022. Payroll contributions ultimately used to purchase shares are reclassified to stockholders' equity on the purchase date.

In June 2022, certain outstanding ESPP offering periods were reset and automatically rolled over into a new ESPP offering period that started on June 15, 2022. The reset was accounted for as a modification, which resulted in an incremental stock-based compensation of $8.7 million, which will be recognized over the remaining term of the modified ESPP offering periods, ranging from approximately 6 months to 18 months.

The fair value of the purchase right for the ESPP was estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions:


	Year Ended July 31,
	2022	2021	2020
Expected term (in years)	0.5 - 2.0	0.5 - 2.0	0.5 - 2.0
Expected stock price volatility	44.1% - 79.4%	46.2% - 67.4%	53.6% - 73.6%
Risk-free interest rate	0.1% - 3.2%	0.1% - 0.2%	0.2% - 1.7%
Dividend yield	0.0%	0.0%	0.0%

Deferred Merger Consideration

In connection with certain business acquisitions, as further described in Note 6, Business Combinations, certain former employees who became our employees are entitled to receive a deferred merger consideration payable in shares of our authorized common stock and RSUs. In connection with the business acquisitions completed in fiscal 2022, we issued a total of 0.1 million unvested shares of our common stock as consideration to certain key employees. The number of unvested shares of common stock issued in connection with business acquisitions in fiscal 2021 and fiscal 2020 was not material. These equity awards are subject to time-based vesting. The fair value of these awards upon the acquisition date of the respective acquisitions totaled approximately $17.0 million, $10.1 million and $9.3 million in fiscal 2022, fiscal 2021 and fiscal 2020, respectively. The fair value of these awards is being recognized as stock-based compensation expense on a straight-line basis over the vesting period within research and development expenses in the consolidated statements of operations.

Stock-based Compensation Expense

The components of stock-based compensation expense recognized in the consolidated statements of operations consisted of the following:


	Year Ended July 31,
	2022		2021		2020

	(in thousands)
Cost of revenue	$	23,847	$	14,036	$	7,318
Sales and marketing	191,091		133,115		66,539
Research and development	118,299		67,803		30,173
General and administrative	76,325		43,581		17,365
Total	$	409,562	$	258,535	$	121,395

As of July 31, 2022, the unrecognized stock-based compensation cost related to outstanding equity-based awards, including awards for which the service inception date has been met but the grant date has not been met, was $1,030.7 million, which we expect to be amortized over a weighted-average period of 2.6 years.

During fiscal 2022, fiscal 2021 and fiscal 2020, we capitalized $11.5 million, $6.3 million and $4.4 million, respectively, of stock-based compensation associated with the development of software for internal-use.

Other	0.1		—		(1.0)
Effective tax rate	(1.7)	%	(1.9)	%	(2.1)	%

Our estimated effective tax rate for the periods presented differs from the U.S. statutory rate primarily due to our foreign earnings which are taxed at different rates than the U.S. statutory rate, as well as the benefit of stock compensation deductions, offset by the impact of the valuation allowance we maintain against our U.S. federal and state deferred tax assets.

During fiscal 2022 and fiscal 2020, we recognized an income tax benefit of $1.0 million and $1.1 million, respectively, as a result of a release in our valuation allowance on deferred tax assets due to deferred taxes recorded as part of the acquisition accounting of business combinations. During fiscal 2021, we did not recognize income tax benefits from business combinations. Refer to Note 6, Business Combinations, for further information. During fiscal 2022, we recognized an income tax benefit of $1.5 million for the refund of withholding taxes related to prior fiscal periods.

The following table presents the tax effects of temporary differences that give rise to significant portions of our deferred tax assets and liabilities:


	July 31,
	2022		2021

	(in thousands)
Deferred tax assets:
Net operating losses carryovers	$	487,298	$	341,777
Accruals and reserves	11,104		7,769
Deferred revenue	69,511		33,028
Tax credits carryovers	68,272		42,225
Stock-based compensation	22,314		21,849
Operating lease liabilities	16,964		10,505
Other	7,759		2,015
Gross deferred tax assets	683,222		459,168
Less: Valuation allowance	(553,916)		(345,756)
Total deferred tax assets	$	129,306	$	113,412

Deferred tax liabilities:
Intangible assets	$	(6,319)	$	(6,341)
Deferred contract acquisition costs	(67,512)		(46,709)
Convertible senior notes	(39,515)		(50,593)
Operating lease right-of-use assets	(15,739)		(9,069)
Total deferred tax liabilities	$	(129,085)	$	(112,712)

Net deferred tax assets	$	221	$	700

A deferred tax liability has not been recognized on the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries that are indefinitely reinvested outside the U.S. Income taxes are generally incurred upon a repatriation of assets, a sale, or a liquidation of the subsidiary. The excess of the amount for financial reporting over the tax basis in the investments in foreign subsidiaries, as well as the unrecognized deferred tax liability, are not material for the periods presented.

The following table presents the change in the valuation allowance:


	Year ended July 31,
	2022		2021		2020

	(in thousands)
Balance as of the beginning of the period	$	345,756	$	130,236	$	103,732
Change during the period	208,160		215,520		26,504
Balance as of the end of the period	$	553,916	$	345,756	$	130,236

The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods. We regularly assess the ability to realize our deferred tax assets and establish a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. We weigh all available positive and negative evidence, including our earnings history and results of recent operations, scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. Due to the weight of objectively verifiable negative evidence, including our history of losses, we believe that it is more likely than not that our U.S. federal and, state deferred tax assets will not be realized as of July 31, 2022 and 2021, and as such, we have maintained a full valuation allowance against such deferred tax assets. Due to the weight of objectively verifiable negative evidence, our U.K. deferred tax assets are more likely than not to be realized in the future and a full valuation allowance was recorded and has been maintained as of July 31, 2022 and 2021.

The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as our projections for growth. In the event we determine that we will be able to realize all or part of our net deferred tax assets in the future, the valuation allowance against our deferred tax assets will be reversed in the period in which we make such determination. The release of a valuation allowance may cause greater volatility in the effective tax rate in the periods in which the valuation allowance is released. The valuation allowance against our U.S. federal, state and U.K. deferred tax assets increased by $208.2 million, $215.5 million and $26.5 million in fiscal 2022, fiscal 2021 and fiscal 2020, respectively. The increase in the valuation allowance in fiscal 2022, fiscal 2021 and fiscal 2020 was related to tax losses for which insufficient positive evidence exists to support their realizability.

As of July 31, 2022 and 2021, we have net operating loss carryforwards for U.S. federal income tax purposes of $2,016.3 million and $1,421.0 million, respectively, which are available to offset future federal taxable income. Beginning in 2027, $177.7 million of the federal net operating losses will begin to expire. The remaining $1,838.6 million of the federal net operating losses will carry forward indefinitely. As of July 31, 2022 and 2021, we have net operating loss carryforwards for state income tax purposes of $700.0 million and $396.3 million, respectively. Beginning in 2024, $532.3 million of state net operating losses will begin to expire at different periods. The remaining $167.7 million of state net operating losses will carry forward indefinitely. As of July 31, 2022 and 2021, we had foreign net operating loss carryforward of $67.8 million and $54.6 million, respectively, all of which will be carried forward indefinitely.

As of July 31, 2022, we had federal and California research and development tax credit carryforwards of approximately $56.2 million and $41.8 million, respectively. If not utilized, the federal credit carryforwards will begin expiring at different periods beginning in 2033. The California credit will be carried forward indefinitely.

Federal and state tax laws impose restrictions on the utilization of net operating loss and research and development tax credit carryforwards in the event of a change in our ownership as defined by the Internal Revenue Code, Sections 382 and 383. Under Section 382 and 383 of the Code, substantial changes in our ownership and the ownership of acquired companies may limit the amount of net operating loss and research and development tax credit carryforwards that are available to offset

taxable income. The annual limitation would not automatically result in the loss of net operating loss or research and development tax credit carryforwards but may limit the amount available in any given future period.

We are subject to income taxes in the U.S. and various foreign jurisdictions. As of July 31, 2022, all years are open for examination and may become subject to examination in the future. Significant judgment is required in evaluating our tax positions and determining our income tax expense for the fiscal year. During the ordinary course of business, there are transactions and calculations for which the ultimate tax determination is uncertain. Our estimate of the potential outcome of any tax position is subject to management’s assessment of relevant risks, facts and circumstances existing at that time. These unrecognized tax benefits are established when we believe that certain positions might be challenged despite the belief that our tax return positions are fully supportable. We recognize interest and penalties associated with our unrecognized tax benefits as a component of our income tax expense. For the periods presented, we did not have material interest or penalties associated with the unrecognized tax benefits in the consolidated financial statements.

We had $29.7 million of gross unrecognized tax benefits as of July 31, 2022, none of which would affect our effective tax rate if recognized due to our U.S. valuation allowance. The gross unrecognized tax benefits relate to income tax positions which, if recognized, would be in the form of additional deferred tax assets that would be offset by a valuation allowance. As of July 31, 2022, we do not believe that our estimates, as otherwise provided for, on such tax positions will significantly increase or decrease within the next twelve months.

The changes in our gross unrecognized tax benefits consisted of the following:


	Amount
	(in thousands)
Balance as of July 31, 2020	$	10,509
Gross decrease for tax positions of prior fiscal years	(581)
Gross increase for tax positions of current fiscal years	8,573
Balance as of July 31, 2021	18,501
Gross increase for tax positions of prior fiscal years	1,129
Gross increase for tax positions of current fiscal year	10,069
Balance as of July 31, 2022	$	29,699

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Net Loss Per Share

12 Months Ended

Jul. 31, 2022

Earnings Per Share [Abstract]

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. The diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, our stock options, shares subject to repurchase from early exercised stock options, share purchase rights under the employee stock purchase plan, unvested RSUs, unvested PSAs, unvested common stock and shares related to the Notes are considered to be potential common stock equivalents.

Since we have reported net losses for all periods presented, we have excluded all potentially dilutive securities from the calculation of the diluted net loss per share as their effect is antidilutive and accordingly, basic and diluted net loss per share is the same for all periods presented.

The following table sets forth the computation of basic and diluted net loss per share:

	2022		2021		2020

	(in thousands, except per share data)
Net loss	$	(390,278)	$	(262,029)	$	(115,116)
Weighted-average shares used in computing net loss per share, basic and diluted	140,895		135,654		129,323
Net loss per share, basic and diluted	$	(2.77)	$	(1.93)	$	(0.89)

The following table summarizes the outstanding potentially dilutive securities that were excluded from the computation of diluted net loss per share because the impact of including them would have been antidilutive:


	July 31,
	2022	2021	2020

	(in thousands)

Unvested RSUs and shares of common stock	6,769	7,440	8,088
Stock options	1,673	2,597	5,175
Unvested PSAs(1)	832	562	723
Share purchase rights under the ESPP	850	344	568
Notes(2)	7,626	7,626	—
Total	17,750	18,569	14,554

(1) The number of unvested PSAs is estimated at 100% of the target number of shares granted and excludes unvested PSAs for which performance conditions have not been established as of July 31, 2022, as they are not considered outstanding for accounting purposes. Refer to Note 13, Stock-Based Compensation, for further information.

(2) The shares underlying the conversion option in the Notes were not considered in the calculation of diluted net loss per share as the effect would have been antidilutive. Based on the initial conversion price, the entire outstanding principal amount of the Notes as of July 31, 2022 would have been convertible into approximately 7.6 million shares of our common stock, which is reflected in the above table. As we expect to settle the principal amount of the Notes in cash, only the amount by which the conversion value exceeds the aggregate principal amount of the Notes (the "conversion spread") is considered in the diluted earnings per share computation under the treasury stock method. The conversion spread has a dilutive impact on diluted net income per share when the average market price of our common stock for a given reporting period exceeds the initial conversion price of $150.80 per share for the Notes. Conversion notices received through July 31, 2022, have not been material. In connection with the issuance of the Notes, we entered into Capped Calls, which will not be included in the computation of the number of diluted shares outstanding, as their effect would be antidilutive. The Capped Calls are expected to partially offset the potential dilution to our common stock upon any conversion of the Notes.

Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jul. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fiscal Year	Fiscal Year Our fiscal year ends on July 31. References to fiscal 2022, for example, refer to our fiscal year ended July 31, 2022.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries and have been prepared in conformity with generally accepted accounting principles in the United States ("GAAP"). All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of revenue recognition, deferred revenue, deferred contract acquisition costs, capitalized internal-use software development costs, valuation of acquired intangible assets, period of benefit generated from our deferred contract acquisition costs, allowance for doubtful accounts, valuation of common stock options and stock-based awards, useful lives of property and equipment, useful lives of acquired intangible assets, recoverability of goodwill, valuation of deferred tax assets and liabilities, loss contingencies related to litigation, fair value and effective interest rate of convertible senior notes and the discount rate used for operating leases. Management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Actual results could differ significantly from these estimates, and such differences may be material to the consolidated financial statements. Due to uncertainty in the macroeconomic environment, including effects of COVID-19 and inflation, there is ongoing disruption in the global economy and financial markets. We are not aware of any specific event or circumstances that would require an update to our estimates, judgments or assumptions or a revision to the carrying value of our assets or liabilities as of the date of issuance of these consolidated financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained.
Foreign Currency	Foreign Currency The functional currency of our foreign subsidiaries is the U.S. dollar. Accordingly, monetary assets and liabilities of our foreign subsidiaries are re-measured into U.S. dollars at the exchange rates in effect at the reporting date, non-monetary assets and liabilities are re-measured at historical rates, revenue and expenses are re-measured at average exchange rates in effect during each reporting period. Foreign currency transaction gains and losses are recorded in other income (expense), net in the consolidated statements of operations. Foreign currency remeasurement gains and losses and foreign currency transaction gains and losses are not significant to the consolidated financial statements.
Concentration of Risks	Concentration of Risks We generate revenue primarily from sale of subscriptions to access our cloud platform, together with related support services. Our sales team, along with our channel partner network of global telecommunications service providers, system integrators and value-added resellers (collectively "channel partners"), sells our services worldwide to organizations of all sizes. Due to the nature of our services and the terms and conditions of our contracts with our channel partners, our business could be affected unfavorably if we are not able to continue our relationships with them. Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments and accounts receivable. Although we deposit our cash with multiple financial institutions, the deposits, at times, may exceed federally insured limits. Cash equivalents and short-term investments consist of highly liquid investments in money market funds, U.S. treasury, U.S. agency securities and corporate debt securities, which are invested through financial institutions in the United States. We grant credit to our customers in the normal course of business. We monitor the financial condition of our customers to reduce credit risk. Refer to Note 2, Revenue Recognition, for information regarding customers with concentration of 10% or more of the total balance of accounts receivable, net.
Segment Information	Segment Information We operate as one reportable and operating segment. Our chief operating decision maker is our chief executive officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.
Revenue Recognition	Revenue Recognition In accordance with Accounting Standards Codification ("ASC") Topic 606, Revenue From Contracts With Customers ("ASC 606"), revenue is recognized when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration that we expect to be entitled to receive in exchange for these services. To achieve the core principle of this standard, we apply the following five steps: 1) Identify the contract with a customer We consider the terms and conditions of the contracts and our customary business practices in identifying our contracts under ASC 606. We determine we have a contract with a customer when the contract is approved, we can identify each party’s rights regarding the services to be transferred, we can identify the payment terms for the services, we have determined the customer has the ability and intent to pay and the contract has commercial substance. We apply 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 and financial information pertaining to the customer. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the service either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the services is separately identifiable from other promises in the contract. Our performance obligations consist of (i) our subscription and support services and (ii) professional and other services. 3) Determine the transaction price The transaction price is determined based on the consideration to which we expect to be entitled in exchange for transferring services to the customer. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of our contracts contain a significant financing component. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price ("SSP"). 5) Recognize revenue when or as we satisfy a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised service to a customer. Revenue is recognized when control of the services is transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those services. We generate all our revenue from contracts with customers and apply judgment in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition. Subscription and Support Revenue We generate revenue primarily from sales of subscriptions to access our cloud platform, together with related support services to our customers. Arrangements with customers do not provide the customer with the right to take possession of our software operating our cloud platform at any time. Instead, customers are granted continuous access to our cloud platform over the contractual period. A time-elapsed output method is used to measure progress because we transfer control evenly over the contractual period. Accordingly, the fixed consideration related to subscription and support revenue is generally recognized on a straight-line basis over the contract term beginning on the date that our service is made available to the customer. The typical subscription and support term is one to three years. Most of our contracts are non-cancelable over the contractual term. Customers typically have the right to terminate their contracts for cause if we fail to perform in accordance with the contractual terms. Some of our customers have the option to purchase additional subscription and support services at a stated price. These options generally do not provide a material right as they are priced at our SSP. Professional and Other Services Revenue Professional and other services revenue consists of fees associated with providing deployment advisory services that educate and assist our customers on the best use of our solutions, as well as advise customers on best practices as they deploy our solution. These services are distinct from subscription and support services. Professional services do not result in significant customization of the subscription service. Revenue from professional services provided on a time and materials basis is recognized as the services are performed. Total professional and other services revenue has historically not been material. Contracts with Multiple Performance Obligations Most of our contracts with customers contain multiple promised services consisting of: (i) our subscription and support services and (ii) professional and other services that are distinct and accounted for separately. The transaction price is allocated to the separate performance obligations on a relative SSP basis. We determine SSP based on our overall pricing objectives, taking into consideration the type of subscription and support services and professional and other services, the geographical region of the customer and the number of users. Variable Consideration Revenue from sales is recorded at the net sales price, which is the transaction price, and includes estimates of variable consideration. The amount of variable consideration that is included in the transaction price is constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue will not occur when the uncertainty is resolved. If our services do not meet certain service level commitments, our customers are entitled to receive service credits, and in certain cases, refunds, each representing a form of variable consideration. We have historically not experienced any significant incidents affecting the defined levels of reliability and performance as required by our subscription contracts. Accordingly, estimated refunds related to these agreements were not material to the periods presented. We provide rebates and other credits within our contracts with certain customers, which are estimated based on the value expected to be earned or claimed on the related sales transaction. Overall, the transaction price is reduced to reflect our estimate of the amount of consideration to which we are entitled based on the terms of the contract. Estimated rebates and other credits were not material during the periods presented.
Accounts Receivable and Allowance	Accounts Receivable and Allowance Accounts receivable are recorded at the invoiced amount and are non-interest bearing. Accounts receivable are stated at their net realizable value, net of an allowance for doubtful accounts. We have a well-established collections history from our customers. Credit is extended to customers based on an evaluation of their financial condition and other factors. In determining the necessary allowance for doubtful accounts, we estimate the lifetime expected credit losses against the existing accounts receivable balance. Our estimate is based on certain factors including historical loss rates, current economic conditions, reasonable and supportable forecasts and customer-specific circumstances. The allowance for doubtful accounts has historically not been material. There were no material write-offs recognized in the periods presented. Accordingly, the movements in the allowance for doubtful accounts were not material for any of the periods presented. We do not have any off-balance-sheet credit exposure related to our customers.
Cash Equivalents	We classify all highly liquid investments purchased with an original maturity of 90 days or less from the date of purchase as cash equivalents and all highly liquid investments with original maturities beyond 90 days at the time of purchase as short-term investments. Our cash equivalents and short-term investments consist of highly liquid investments in money market funds, U.S. treasury securities, U.S. government agency securities and corporate debt securities.
Short-Term Investments	We classify our investments as available-for-sale investments and present them within current assets since these investments represent funds available for current operations and we have the ability and intent, if necessary, to liquidate any of these investments in order to meet our liquidity needs or to grow our business, including for potential business acquisitions or other strategic transactions. Our investments are carried at fair value, with unrealized gains and losses unrelated to credit loss factors reported in accumulated other comprehensive income (loss) ("AOCI"). Our investments are reviewed periodically when there is a decline in a security’s fair value below the amortized cost basis. We consider our intent to sell and whether it is more likely than not that we will be required to sell the securities before the recovery of its cost basis. If either of these criteria are triggered, the amortized cost basis of the debt security is written down to fair value through other income (expense), net. If neither criteria is met, we evaluate whether the decline in fair value below the amortized cost basis is related to credit-related factors or other factors such as interest rate fluctuations. The factors considered in this analysis include the extent the fair value is less than the amortized cost basis, whether there were changes to the rating of the security by a ratings agency, whether the issuer has failed to make scheduled interest payments and other adverse conditions as applicable. Credit-related impairment losses, limited by the amount that the fair value is less than the amortized cost basis, are recorded through an allowance for credit losses in other income (expense), net. For purposes of identifying and measuring credit-related impairments, our policy is to exclude the applicable accrued interest from both the fair value and amortized cost basis of the related debt security. Accrued interest receivable, net of the allowance for credit losses, if any, is recorded to prepaid expenses and other current assets. There were no credit-related impairments recognized on our investments during the periods presented. Interest income, amortization (accretion) of investments purchased at a premium (discount) and realized gains and losses are included in interest income in the consolidated statements of operations. We use the specific identification method to determine the cost in calculating realized gains and losses upon the sale of these investments.
Strategic Investments	Strategic Investments Our strategic investments consist of non-marketable equity investments of privately held companies. Investments in non-marketable equity investments of privately held companies without readily determinable fair values are measured using the measurement alternative, as we have less than 20% ownership and do not have the ability to exercise significant influence over their operations. The carrying amount of non-marketable equity investments is adjusted based on observable price changes from orderly transactions for identical or similar investments of the same issuer and by impairments, when events or circumstances indicate a decline in value has occurred. Non-marketable equity investments that have been remeasured during the period due to an observable event or impairment are classified within Level 3 in the fair value hierarchy because we estimate the value based on valuation methods which may include a combination of the observable transaction price at the transaction date and other unobservable inputs including volatility, rights, and obligations of the investments we hold. Our strategic investments are included within other noncurrent assets in the consolidated balance sheets and adjustments to their carrying amounts are recorded in other income (expense), net in the consolidated statements of operations. There were no material events or circumstances impacting the carrying amount of our strategic investments during the periods presented.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Our financial instruments consist of cash equivalents, short-term investments, accounts receivable, accounts payable, accrued liabilities and convertible senior notes. Cash equivalents and short-term investments are recorded at fair value. 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 recorded at fair value on a recurring basis in the consolidated balance sheets, consisting of cash equivalents and short-term investments, are categorized in accordance with the fair value hierarchy based upon the level of judgment associated with the inputs used to measure their fair values. Convertible senior notes are carried at the initially allocated liability value less unamortized debt discount and issuance costs on the consolidated balance sheets, and the fair value of the convertible senior notes is presented at each reporting period for disclosure purposes only.
Property and Equipment	Property and Equipment Property and equipment, net are stated at historical cost net of accumulated depreciation. Property and equipment, excluding leasehold improvements, are depreciated using the straight-line method over the estimated useful lives of the respective assets, generally ranging from three to five years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the respective assets or the lease term. Expenditures for maintenance and repairs are expensed as incurred and significant improvements and betterments that substantially enhance the life of an asset are capitalized.
Capitalized Internal-Use Software Development Costs	Capitalized Internal-Use Software Development CostsWe capitalize certain costs incurred during the application development stage in connection with software development for our cloud security platform. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Capitalized costs are recorded as part of property and equipment in the consolidated balance sheets. Maintenance and training costs are expensed as incurred. Capitalized internal-use software is amortized on a straight-line basis over its estimated useful life, which is generally three years, and is recorded as cost of revenue in the consolidated statements of operations.
Business Combinations	Business Combinations We account for our business combinations using the acquisition method of accounting, which requires, among other things, allocation of the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed at their estimated fair values on the acquisition date. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, we make estimates and assumptions, especially with respect to intangible assets. Our estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, we may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill if new information is obtained related to facts and circumstances that existed as of the acquisition date. After the measurement period, any subsequent adjustments are reflected in the consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred.
Goodwill and Intangible Assets	Goodwill represents the excess of the fair value of purchase consideration in a business combination over the fair value of net tangible and intangible assets acquired. Goodwill amounts are not amortized, but rather tested for impairment at least annually or more often if circumstances indicate that the carrying value may not be recoverable. There was no impairment of goodwill during any of the periods presented. Acquired intangible assets consist of identifiable intangible assets, including developed technology and customer relationships, resulting from business combinations. Acquired finite-lived intangible assets are initially recorded at fair value and are amortized on a straight-line basis over their estimated useful lives. Amortization expense of developed technology and customer relationships is recorded primarily within cost of revenues and sales and marketing expenses, respectively, in the consolidated statements of operations.
Impairment of Long-Lived Assets	Long-lived assets, such as property and equipment and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. We measure the recoverability of these assets by comparing the carrying amounts to the future undiscounted cash flows that these assets are expected to generate. If the total of the future undiscounted cash flows are less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the asset exceeds the fair value.
Derivative Instruments	Derivative Instruments We enter into foreign currency forward contracts, a portion of which we designate as cash flow hedges, in order to manage the volatility of cash flows that relate to our cost of revenues and operating expenses denominated in foreign currencies. Gains or losses related to our cash flow hedges are recorded as a component of AOCI on the consolidated statements of stockholders' equity until the forecasted transaction occurs in earnings. When the forecasted transaction occurs, the related gains and losses are reclassified into earnings within the financial statement line item associated with the underlying hedged transaction. If the underlying hedged transaction does not occur, or it becomes probable that the hedged transaction will not occur, the cumulative unrealized gain or loss is reclassified immediately from AOCI into earnings within the financial statement line item associated with the underlying hedged transaction. We measure hedge effectiveness using regression analysis at hedge inception and periodically thereafter. We include time value in our effectiveness assessment. We recognize changes in the fair value of non-designated derivative instruments within other income (expense), net in the consolidated statements of operations in the same period that the fair value measurement occurs. All of our derivative instruments are measured at fair value. We have elected to present the derivative assets and derivative liabilities on a gross basis on the consolidated balance sheets. Derivative instruments are classified in the consolidated statements of cash flows as cash from operating activities, which reflect the classification of the underlying hedged transactions.
Operating Leases	Operating Leases We enter into operating lease arrangements for real estate assets related to office space and co-location assets related to space and racks at data center facilities. We determine if an arrangement contains a lease at its inception by assessing whether there is an identified asset and whether the arrangement conveys the right to control the use of the identified asset in exchange for consideration. Operating leases related balances are included in "operating lease right-of-use assets," "operating lease liabilities," and "operating lease liabilities, noncurrent" in the consolidated balance sheets. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make payments arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments consist of the fixed payments under the arrangement. The operating lease liabilities are adjusted for any unpaid lease incentives, such as tenant improvement allowances. Variable costs, such as maintenance and utilities based on actual usage, are not included in the measurement of right-to-use assets and lease liabilities but are expensed when the event determining the amount of variable consideration to be paid occurs. As the implicit rate of our leases is not determinable, we use an incremental borrowing rate ("IBR") based on the information available at the lease commencement date in determining the present value of lease payments. The lease expense is recognized on a straight-line basis over the lease term. We generally use the base, non-cancelable lease term when recognizing the right-of-use assets and lease liabilities, unless it is reasonably certain that a renewal or termination option will be exercised. We account for lease components and non-lease components as a single lease component. Leases with a term of twelve months or less are not recognized on the consolidated balance sheets. We recognize lease expense for these leases on a straight-line basis over the term of the lease.
Stock-Based Compensation	Stock-Based Compensation Compensation expense related to stock-based awards granted to employees and non-employees is calculated based on the fair value of stock-based awards on the date of grant. We recognize stock-based compensation expense over an award’s requisite service period based on the award’s fair value. Stock-based compensation for common stock options is recognized based on the fair value of the awards granted, determined using the Black-Scholes option pricing model. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period, generally four years. Stock-based compensation for purchase rights granted under the employee stock purchase plan is based on the fair value of the number of awards estimated at the beginning of the offering period, as determined using the Black-Scholes option pricing model. Stock-based compensation expense is recognized following the straight-line attribution method over the offering period. Stock-based compensation for restricted stock units is measured based on the market closing price of our common stock on the grant date. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period, generally four years. Stock-based compensation for performance stock awards (“PSAs”), which have the same grant date and service inception date, is based on the probable number of shares to be attained and the market closing price of our common stock at the grant date. For PSAs where the service inception date of the awards precedes the grant date, stock-based compensation expense is recognized based on the number of PSAs for which it is probable that the performance condition will be met, using the accelerated attribution method and the market closing price of our common stock at each reporting date up to the grant date. The number of these PSAs for which it is probable that the performance condition will be met is determined using management’s best estimate at the end of each reporting period. At the completion of the performance period for these PSAs, any earned PSAs are granted upon approval of the compensation committee of our board of directors.
Convertible Senior Notes	Convertible Senior Notes In accounting for the issuance of the convertible senior notes, we separated the convertible senior notes into liability and equity components. The carrying amounts of the liability component was calculated by measuring the fair value of similar liabilities that do not have associated convertible features. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the convertible senior notes as a whole. This difference represents the debt discount that is amortized to interest expense over the respective terms of the convertible senior notes using the effective interest rate method. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the related debt issuance costs, we allocated the total amount incurred to the liability and equity components of the convertible senior notes based on their relative values. Issuance costs attributable to the liability component are being amortized to interest expense over the contractual term of the convertible senior notes. The issuance costs attributable to the equity component were netted against the equity component representing the conversion option in additional paid-in capital. To the extent that we receive the convertible senior notes conversion requests prior to their maturity, a portion of the equity component is classified as temporary equity, which is measured as the difference between the principal and net carrying amount of the convertible senior notes requested for conversion. Upon settlement of the conversion requests, the difference between the fair value and the amortized book value of the liability component of the convertible senior notes requested for conversion is recorded as a gain or loss on early note conversion. The fair value of the convertible senior notes is measured based on a similar liability that does not have an associated convertible feature based on the remaining term of the convertible senior notes.
Research and Development	Research and Development Our research and development expenses support our efforts to add new features to our existing offerings and to ensure the reliability, availability and scalability of our solutions. Our cloud platform is software-driven, and our research and development teams employ software engineers in the design and the related development, testing, certification and support of our solutions. Accordingly, the majority of our research and development expenses result from employee-related costs, including salaries, bonuses, benefits, stock-based compensation and costs associated with technology tools used by our engineers.
Advertising Expenses	Advertising ExpensesAdvertising expenses are charged to sales and marketing expenses in the consolidated statements of operations as incurred.
Warranties and Indemnification	Warranties and Indemnification Our cloud platform is generally warranted to be free of defects under normal use and to perform substantially in accordance with the subscription agreement. Additionally, our contracts generally include provisions for indemnifying customers and channel partners against liabilities if our services infringe or misappropriate a third party’s intellectual property rights. Costs and liabilities incurred as a result of warranties and indemnification obligations were not material during the periods presented.
Legal Contingencies	Legal Contingencies We may be subject to legal proceedings and litigation arising from time to time. We record a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. We periodically evaluate developments in our legal matters that could affect the amount of liability that we accrue, if any, and adjust, as appropriate. Until the final resolution of any such matter for which we may be required to record a liability, there may be a loss exposure in excess of the liability recorded and such amount could be significant. We expense legal fees as incurred.
Income Taxes	Income Taxes We account for income taxes using the asset and liability method. Deferred income taxes are recognized by applying the enacted statutory tax rates applicable to future years to differences between the carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and tax credit carryforwards. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance to amounts that are more likely than not to be realized. We recognize tax benefits from uncertain tax positions only if we believe that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement.
Comprehensive Loss	Comprehensive Loss Comprehensive loss is comprised of the net loss and other comprehensive income (loss). Our other comprehensive income (loss) includes unrealized gains and losses on available-for-sale securities and unrealized gains and losses and realized gains and losses reclassified into net loss on cash flow hedges, as reflected in the consolidated statements of comprehensive loss.
Net Loss Per Share	Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted earnings per share adjusts basic earnings per share for all potentially dilutive common stock equivalents outstanding during the period. Potentially dilutive securities consist primarily of stock options, shares subject to repurchase from early exercised stock options, share purchase rights under the employee stock purchase plan, unvested restricted stock units ("RSUs"), unvested performance stock awards ("PSAs"), unvested common stock and shares related to convertible senior notes. Since we have reported net losses for all periods presented, we have excluded all potentially dilutive securities from the calculation of the diluted net loss per share, as their effect is antidilutive. Accordingly, basic and diluted net loss per share is the same for all periods presented.
Recently Adopted Accounting Pronouncements; Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU No. 2019-12, Income Taxes (Topic 740) ("ASU 2019-12"): Simplifying the Accounting for Income Taxes. The new standard eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences related to changes in ownership of equity method investments and foreign subsidiaries. The guidance also simplifies aspects of accounting for franchise taxes and enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. For public business entities, it is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. We early adopted this standard in the second quarter of fiscal 2020 and it did not have a material impact to the consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities to require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of operations. We adopted this standard in the first quarter of fiscal 2021 and it did not have a material impact to the consolidated financial statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805) on Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This standard requires contract assets and contract liabilities from contracts with customers that are acquired in a business combination to be recognized and measured as if the acquirer had originated the original contract. Previously, acquired contract assets and liabilities were measured at fair value. This standard is effective for us in the first quarter of fiscal 2024, though early adoption is permitted. We early adopted this standard in the first quarter of fiscal 2022 and it did not have a material impact to the consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) ("ASU 2020-06"). This standard removes the separation model for convertible debt with a cash conversion feature and convertible instruments with a beneficial conversion feature. Such convertible debt will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The update also requires the if-converted method to be used for convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. We adopted this standard effective on August 1, 2022, the beginning of fiscal 2023, using the modified retrospective method. This standard will result in our convertible senior notes being accounted for as a single unit of debt and we will no longer be required to record the conversion feature in equity. This will further eliminate the need for amortization of the debt discount as interest expense and the portion of the issuance costs initially allocated to equity will be classified to debt and amortized as interest expense. As of August 1, 2022, the adoption of this new standard resulted in an increase of $169.9 million to the carrying amount of the convertible senior notes, a decrease of $273.7 million to additional paid-in capital and a cumulative-effect adjustment of $103.8 million to accumulated deficit.
