Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business PagerDuty, Inc. was incorporated under the laws of the state of Delaware in May 2010. PagerDuty acts as the central nervous system for the digital enterprise. PagerDuty harnesses digital signals from virtually any software-enabled system or device, combines it with human response data and orchestrates teams to take the right actions in real time. The Company’s products help organizations improve operations, accelerate innovation, increase revenue, mitigate security risk, and deliver a great customer experience. As used herein, “PagerDuty”, “we”, “our”, “the Company” and similar terms include PagerDuty, Inc., unless the context indicates otherwise. Initial Public Offering On April 15, 2019, the Company completed its initial public offering (“IPO”), pursuant to which the Company issued and sold 9,860,500 shares of common stock, inclusive of the over-allotment option, at a public offering price of $24.00 per share. The Company received net proceeds of $213.7 million, after deducting underwriters' discounts and commissions of $16.6 million and other issuance costs of $6.4 million. Immediately prior to the closing of the Company’s IPO, all shares of the redeemable convertible preferred stock automatically converted into 41,273,345 shares of common stock. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the consolidated accounts of PagerDuty. All intercompany balances and transactions have been eliminated upon consolidation. The Company’s fiscal year ends on January 31. References to fiscal 2021, for example, refer to the fiscal year ended January 31, 2021. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make, on an ongoing basis, estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. The Company’s most significant estimates and judgments involve the valuation of the Company’s stock-based awards, including the determination of fair value of common stock (prior to the closing of the IPO) and the fair value of the employee stock purchase plan (“ESPP”) expense, period of benefit for amortizing deferred contract costs, the determination of the allowance for doubtful accounts, the provision for income taxes, including the related valuation allowance and any uncertain tax positions, fair value of the liability and equity components of the Convertible Senior Notes (the “Notes”), fair value of acquired assets and assumed liabilities, impairment of goodwill and intangible assets, the incremental borrowing rate for lease liabilities, and estimates related to our revenue recognition, such as the assessment of performance obligations in our revenue arrangements and the fair value assigned to each performance obligation, among others. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. In December 2019, the novel coronavirus and resulting disease (“COVID-19”) was reported and in March 2020 the World Health Organization declared it a pandemic. The extent of the impact of COVID-19 on our operational and financial performance will depend on certain developments, including the duration and spread of the outbreak, impact on our customers and our sales cycles, and impact on our employees, as discussed in more detail in the Overview section of our Management’s Discussion and Analysis. During the fiscal year ended January 31, 2021, this uncertainty resulted in a higher level of judgment related to our estimates and assumptions related to the estimate of credit losses for accounts receivable. As of the date of issuance of the financial statements, we are not aware of any specific event or circumstance that would require us to update our estimates, judgments, or revise the carrying value of our assets or liabilities. These estimates may change as new events occur and additional information is obtained and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to our financial statements. Stock Split In May 2018, the Company effected a two-for-one stock split of the Company’s redeemable convertible preferred stock and common stock effective May 3, 2018. All redeemable convertible preferred stock and common stock share and per-share amounts for the periods presented in these financial statements have been retroactively adjusted for the stock split as if such stock split occurred on the first day of the periods presented.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Segment Information The Company manages its operations and allocates resources as one operating segment. The Company’s chief operating decision maker (“CODM”) is its chief executive officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, and allocating resources. Refer to Note 14, “Geographic Information” for information regarding the Company's long-lived assets and revenue by geography. Revenue Recognition The Company generates revenue primarily from cloud-hosted subscription fees with the majority of its revenue from such arrangements. The Company also generates an immaterial amount of revenue from term license software subscription fees. Revenue is recognized when control of these services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The Company accounts for revenue contracts with customers by applying the requirements of Topic 606, which includes the following steps: • Identification of the contract, or contracts, with a customer. • Identification of the performance obligations in the contract. • Determination of the transaction price. • Allocation of the transaction price to the performance obligations in the contract. • Recognition of revenue when, or as, the Company satisfies a performance obligation Cloud-hosted software subscriptions The Company’s cloud-hosted software subscriptions allow customers to use its cloud-hosted software over the contract period without taking possession of the software. The Company’s cloud-hosted software subscription agreements generally have monthly or annual contractual terms. Revenue related to our cloud-hosted software subscriptions is recognized ratably over the related contractual term beginning on the date that the Company’s platform is made available to a customer. Access to the platform represents a series of distinct services as the Company continually provides access to, and fulfills its obligation to, the end customer over the subscription term. The series of distinct services represents a single performance obligation that is satisfied over time. The Company recognizes revenue ratably because the customer receives and consumes the benefits of the platform throughout the contract period. Term license software subscriptions The Company’s term license software subscriptions provide both an obligation to provide access to its on-premise software, which includes both open source and proprietary features, as well as an obligation to provide support and maintenance. The Company’s term license software subscription agreements generally have annual contractual terms. The Company accounts for the license to the software and support as two separate performance obligations. As the open source software is publicly available at no cost to the customer, the Company has determined that there is no value to be assigned to the open source software in the term license software subscription arrangements. The proprietary software license represents a promise to provide a license to use functional intellectual property that is recognized at a point in time on the date access to the software is made available to the customer and the term license software subscription period has begun. The Company has concluded the support is a stand-ready performance obligation that consists of a series of distinct services that are satisfied ratably over time as the services are provided. The Company uses a time-based output method to measure progress because efforts are expended evenly throughout the period given the nature of the promise is a stand-ready service. The Company recognizes support revenue ratably, typically beginning on the start of the contractual term of the arrangement. In order to determine the stand-alone selling price, the Company conducts a periodic analysis that requires judgment and considers multiple factors that are reasonably available and maximizes the use of observable inputs that may vary over time depending upon the unique facts and circumstances related to each performance obligation. To have observable inputs, the Company requires that a substantial majority of the stand-alone selling prices for a product offering fall within a pricing range. The Company believes that this analysis results in an estimate that approximates the price that would be charged for the product offerings if they were sold separately. The Company’s cloud-hosted and term-license software subscription arrangements are generally non-cancellable and do not contain refund provisions. The Company bills for monthly cloud-hosted and term-license software subscriptions on a monthly basis and annually in advance for arrangements with terms of one year or more. The price of the cloud-hosted and term-license software subscriptions is generally fixed at contract inception and therefore, the Company’s contracts do not contain a significant amount of variable consideration. As a result, the amount of revenue recognized in the periods presented from performance obligations satisfied (or partially satisfied) in previous periods due to changes in the transaction price was not material. The Company’s revenue excludes sales and other indirect taxes. Accounts Receivable and Related Allowance Accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based upon historical loss patterns, the age of each past due invoice, and an evaluation of the potential risk of loss associated with delinquent accounts. The allowance also reflects current market conditions and reasonable and supportable forecasts of future economic conditions. As of January 31, 2021, the allowance reflects considerations related to the COVID-19 pandemic and may increase in future periods as we ascertain future impacts to our customers and business. The allowance for doubtful accounts was $1.2 million and $0.8 million as of January 31, 2021 and January 31, 2020. Activity related to the Company’s allowance for doubtful accounts was as follows: Amount (in thousands) Balance as of January 31, 2019 $ 2,360 Charged to bad debt expense 11 Write-offs, net of recoveries (1,561) Balance as of January 31, 2020 $ 810 Charged to bad debt expense 1,188 Write-offs, net of recoveries (810) Balance as of January 31, 2021 $ 1,188 Deferred Revenue The Company records contract liabilities to deferred revenue when amounts are invoiced in advance of performance. Deferred revenue consists of the unearned portion of customer billings. The Company’s payment terms generally provide for payment within 30 days of the invoice date. Amounts anticipated to be recognized within one year of the balance sheet date are recorded as deferred revenue, current; the remaining portion is recorded as deferred revenue, non-current in the consolidated balance sheets. The Company applied the practical expedient in Topic 606 and did not evaluate contracts of one year or less for the existence of a significant financing component. For contracts with terms of more than a year, the Company has determined its contracts generally do not include a significant financing component as these all relate to contracts that are billed annually in advance. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s cloud- hosted software subscription, not to receive financing from its customers or to provide customers with financing. Deferred Contract Costs Deferred contract costs consist of sales commissions earned by the Company’s sales force which are considered incremental and recoverable costs of obtaining a contract with a customer. The Company determined that sales commissions that are related to contract renewals are not commensurate with commissions earned on the initial contract. Accordingly, sales commissions for initial contracts are deferred and then amortized on a straight-line basis over a period of benefit that the Company has determined to be four years. The Company determined the period of benefit by taking into consideration its customer contracts, technology, and other factors. Amounts anticipated to be recognized within one year of the balance sheet date are recorded as deferred contract costs, current; the remaining portion is recorded as deferred contract costs, noncurrent in the consolidated balance sheets. Deferred contract costs are periodically reviewed for impairment. Amortization of deferred contract costs is included in sales and marketing expense in the consolidated statements of operations. Deferred contract costs on the Company’s consolidated balance sheets were $31.6 million and $25.7 million as of January 31, 2021 and 2020, respectively. Amortization expense was $11.0 million, $7.8 million, and $4.5 million for the fiscal years ended January 31, 2021, 2020, and 2019, respectively. There was no impairment loss in relation to the costs capitalized for the periods presented. The following table represents a rollforward of the Company’s deferred contract costs: Amount (in thousands) Balance as of January 31, 2019 $ 17,472 Additions to deferred contract costs 15,996 Amortization of deferred contract costs (7,780) Balance as of January 31, 2020 $ 25,688 Additions to deferred contract costs 16,876 Amortization of deferred contract costs (10,977) Balance as of January 31, 2021 $ 31,587 Concentrations of Risk and Significant Customers The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, held-to-maturity investments, available-for-sale investments, and accounts receivable. All of the Company’s cash and cash equivalents and investments are invested in money market funds, United States (“U.S.”) Treasury securities, commercial paper, corporate debt securities, or U.S. Government agency securities that management believes to be of high credit quality. No single customer accounted for more than 10% of the total accounts receivable balance as of January 31, 2021 or 2020. No single customer represented 10% or more of revenue for the fiscal years ended January 31, 2021, 2020, or 2019. Cost of Revenue Cost of revenue primarily consists of expenses related to providing the Company’s cloud- hosted software subscription to customers, including personnel expenses for operations and global support, payments to our third-party cloud infrastructure providers for hosting the Company’s software, payment processing fees, amortization of capitalized internal-use software costs, amortization of acquired developed technology, and allocated overhead costs for facilities, information technology, and other allocated overhead costs. Foreign Currency Remeasurement The functional currency of the Company’s international subsidiaries is the United States dollar. Accordingly, monetary balance sheet accounts are remeasured using exchange rates in effect at the balance sheet dates and non-monetary items are remeasured at historical exchange rates. Revenue and expenses are remeasured at the average exchange rates for the period. Foreign currency transaction gains and losses are included in other income, net and were not material for the fiscal years ended January 31, 2021, 2020, or 2019. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, highly liquid investments with original maturities of three months or less from the date of purchase, and money market funds. Investments The Company’s investments are classified as available-for-sale and held-to-maturity and consist of highly liquid investments, primarily U.S. Treasury securities, commercial paper, corporate debt securities, and U.S. Government agency securities. The Company determines the appropriate classification of its investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company periodically evaluates its short-term investments to assess whether those with unrealized loss positions are impaired. The Company considers various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value is less than the Company’s cost basis, and the financial condition and near-term prospects of the investee. If the Company determines that the investment is impaired, an impairment loss is recognized in earnings equal to the difference between the investment’s amortized cost and fair value at such date. Realized gains and losses are reported in other income, net, in the consolidated statements of operations. No impairment charges have been recognized to date. Held-to-maturity The Company’s held-to-maturity investments consist of investments with maturities over three months from the date of purchase and less than 12 months from the date of the balance sheet and are classified as short-term. The Company has the ability and positive intent to hold these investments to maturity. Held-to-maturity investments are carried at amortized cost, which approximates fair value. Available-for-sale The Company classifies its available-for-sale investments, including those with stated maturities beyond twelve months, as short-term based on their highly liquid nature and because they represent the investment of cash that is available for current operations. In addition, the Company may sell these investments at any time for use in its current operations or for other purposes, even prior to maturity. The Company's available-for-sale investments are recorded at fair market value each reporting period. Unrealized gains and losses on these available-for-sale investments are reported as a separate component of accumulated other comprehensive income in the accompanying consolidated balance sheet until realized. Related Party Transactions Certain members of the Company’s Board of Directors serve as directors of, or are executive officers of, and in some cases are investors in, companies that are customers or vendors of the Company. The Company recognized revenues from the sales of its product to a related party of $1.1 million and $1.0 million in the fiscal years ended January 31, 2021, and 2020, respectively, and billings of $1.1 million in the fiscal year ended January 31, 2021 . Additionally, the Company recognized $1.2 million in expenses related to purchases and had $1.1 million in cash disbursements to these companies during the year ended January 31, 2021. Other related party transactions were not material for the fiscal years ended January 31, 2021, 2020, or 2019. Property and Equipment, Net Property and equipment, net, are stated at cost less accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the respective assets, which is generally three Property and equipment is reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If property and equipment are considered impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. If the estimated useful life assumption is reduced for any asset, the remaining unamortized balance would be amortized or depreciated over the revised estimated useful life. Research and Development Expense Research and development expenses consist primarily of personnel costs for the Company’s engineering, product, and design teams. Additionally, research and development expenses include contractor fees, depreciation of equipment used in research and development activities, acquisition-related expenses, and allocated overhead costs. Research and development costs are expensed as incurred. Internal-Use Software Costs The Company evaluates costs related to the development of its platform and certain projects for internal use incurred during the application development stage. Costs related to preliminary project activities and post-implementation activities are expensed as incurred and costs related to the application development stage are capitalized. Internal-use software is amortized on a straight-line basis over its estimated useful life of three years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The Company capitalized $1.0 million during the fiscal year ended January 31, 2021. No internal-use software costs were capitalized during the fiscal years ended January 31, 2020 or 2019. Business Combinations The Company applies the acquisition method of accounting for business combinations. Under this method of accounting, all assets acquired and liabilities assumed are recorded at their respective fair values at the date of the acquisition. The purchase consideration is allocated to the net tangible and identifiable intangible assets. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions. These estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. Goodwill, Acquired Intangible Assets, and Impairment of Long-Lived Assets Goodwill. Goodwill represents the excess purchase consideration of an acquired business over the fair value of the net tangible and identifiable intangible assets. Goodwill is evaluated for impairment annually in the fourth quarter, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate or a significant decrease in expected cash flows. No impairment charges were recorded during the fiscal years ended January 31, 2021, 2020, or 2019. Acquired Intangible Assets. Acquired intangible assets consist of identifiable intangible assets, primarily developed technology and customer relationships, resulting from the Company’s business acquisition. Intangible assets are recorded at fair value on the date of acquisition and amortized over their estimated useful lives. Impairment of Long-Lived Assets. The carrying amounts of the Company’s long-lived assets, including property and equipment, lease right-of-use assets, capitalized internal-use software, and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful lives are shorter than originally estimated. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If long-lived assets are considered impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. If the Company reduces the estimated useful life assumption for any asset, the remaining unamortized balance would be amortized or depreciated over the revised estimated useful life. Convertible Senior Notes The Notes are accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Subtopic 470-20, Debt with Conversion and Other Options . Pursuant to ASC Subtopic 470-20, issuers of certain convertible debt instruments, such as the Notes, that have a net settlement feature and may be settled wholly or partially in cash upon conversion are required to separately account for the liability (debt) and equity (conversion option) components of the instrument. The carrying amount of the liability component of the instrument is computed by estimating the fair value of a similar liability without the conversion option using a market-based approach. The amount of the equity component is then calculated by deducting the fair value of the liability component from the principal amount of the instrument. The difference between the principal amount and the liability component represents a debt discount that is amortized to interest expense over the respective term of the Notes using the effective interest rate method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the Notes, the allocation of issuance costs incurred between the liability and equity components was based on their relative values. Advertising Costs Advertising costs are expensed as incurred and are included in sales and marketing expense. Advertising costs were $10.1 million, $5.1 million, and $5.1 million for the years ended January 31, 2021, 2020, and 2019, respectively. Stock-Based Compensation The Company recognizes compensation expense for all stock-based payment awards, including stock options and restricted stock units (“RSUs”), based on the estimated fair value of the award on the grant date. The Company estimates the fair value of stock options issued to employees on the date of grant using the Black-Scholes option pricing model, which is impacted by the estimated fair value of the Company’s common stock, as well as certain assumptions including the expected volatility over the term of the option awards, the expected term of the awards, risk-free interest rates and the expected dividend yield. Assumptions and estimates used in the determination of the fair value of stock options are as follows: Expected volatility —Expected volatility is a measure of the amount by which the stock price is expected to fluctuate. Since the Company does not have sufficient trading history for its common stock, it estimates the expected volatility of its stock options by taking the average historical volatility of a group of comparable publicly traded companies over a period equal to the expected life of the options. Expected term —The Company determines the expected term based on the average period the stock options are expected to remain outstanding, generally calculated as the midpoint of the stock options’ vesting term and contractual expiration period, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior. Risk-free rate —The Company uses the U.S. Treasury yield for its risk-free interest rate that corresponds with the expected term. Expected dividend yield —The Company utilizes a dividend yield of zero, as it does not currently issue dividends and does not expect to in the future. Fair value of common stock Prior to the IPO, in accordance with the American Institute of Certified Public Accountants Accounting and Valuation Guide, Valuation of Privately-Held Company Equity Securities Issued as Compensation , the Company’s board of directors exercised reasonable judgment and considered numerous objective and subjective factors to determine the best estimate of fair value of the Company’s common stock, including but not limited to contemporaneous valuations of our common stock performed by independent third-party specialists; the prices, rights, preferences, and privileges of redeemable convertible preferred stock relative to those of common stock; the prices at which the Company sold shares of its common stock to third-party investors and in secondary transactions in arm’s-length transactions; the Company’s operating and financial performance; and additional relevant economic information. The Company estimates the fair value of RSUs at our stock price on the grant date. The Company estimates the fair value of shares to be issued under the ESPP on the first day of the offering period using the Black-Scholes valuation model, which is impacted by the estimated fair value of the Company’s common stock, as well as certain assumptions including the expected volatility over the term of the offering period, the expected term of the awards, risk-free interest rates and the expected dividend yield. Assumptions used in the determination of the fair value of the ESPP are the same as those used in the determination of the fair value of our stock options. The Company recognizes compensation expense for employee stock-based payment awards on a straight-line basis over the period during which an award recipient is required to provide services in exchange for the award (generally the vesting period of the award). The Company accounts for forfeitures as they occur. The fair value of each non-employee stock option is estimated at the date of grant using the Black-Scholes option pricing model and is not remeasured over the vesting term. Assumptions used in valuing non-employee stock options are generally consistent with those used for employee stock options with the exception that the expected term is over the contractual life. Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, the Company recognizes deferred income tax assets and liabilities for the expected future consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as for net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. The Company recognizes the deferred income tax effects of a change in tax rates in the period of enactment. The Company records a valuation allowance to reduce its deferred tax assets to the net amount that it believes is more likely than not to be realized. The Company considers all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing tax planning strategies in assessing the need for a valuation allowance. Realization of its deferred tax assets is dependent primarily upon future U.S. taxable income. The Company recognizes income tax benefits from uncertain tax positions only if it believes that it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such uncertain tax positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Although the Company believes that it has adequately reserved for its uncertain tax positions (including net interest and penalties), it can provide no assurance that the final tax outcome of these matters will not be materially different. The Company makes adjustments to these reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made and could have a material impact on its financial position, results of operations, and cash flows. Net Loss Per Common Share Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period giving effect to all potentially dilutive securities to the extent they are dilutive. The dilutive effect of potentially dilutive securities is reflected in diluted net loss per share by application of the treasury stock method. Basic and diluted net loss per common share were the same for each period presented as the inclusion of all potential common shares outstanding would have been anti-dilutive. Recently Issued Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2020-06, Debt—Debt with Conversion Options (“Subtopic 470-20”) and Derivatives and Hedging—Contracts in Entity’s Own Equity (“Subtopic 815-40”) (“ASU 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity's own equity. ASU 2020-06 also improves and amends the related Earnings Per Share guidance for both Subtopics. The ASU is part of the FASB's simplification initiative, which aims to reduce unnecessary complexity in U.S. GAAP. ASU 2020-06 will be effective for annual reporting periods beginning after December 15, 2021. Early adoption is permitted, but not before annual reporting periods beginning after December 15, 2020. The Company will early adopt this ASU using the modified retrospective method beginning February 1, 2021. While the adoption remains in progress, the Company expects that the adoption will result in a decrease to our accumulated deficit as of February 1, 2021 related to the interest expense from the amortization of the debt discount. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (“Topic 842”) (“ASU 2016-0”2) , which would require lessees to recognize most leases on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The Company adopted the standard using the optional alternative method on a prospective basis with an effective date as of the beginning of the Company’s fiscal year, February 1, 2020, and applied it to the operating leases that existed on that date. Prior year comparative financial information was not recast under the new standard and continues to be presented under ASC 840. The Company elected to utilize the package of practical expedients available for expired or existing contracts which allowed the Company to carryforward historical assessments of (a) whether contracts are or contain leases, (b) lease classification, and (c) initial direct costs. The Company elected to apply the short-term lease exception for all leases. Under the short-term lease exception, the Company will not recognize right-of-use assets or lease liabilities for leases that, at the acquisition date, have a remaining lease term of 12 months or less. As a result of implementing this guidance, the Company recognized a net operating right-of-use asset of $29.1 million and a $35.9 million operating lease liability in its consolidated balance sheets as of February 1, 2020. The adoption of this guidance did not affect the Company’s consolidated statements of operations or consolidated statements of cash flows. Refer to Note 7, “Leases” for further information. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments—Credit Losses (“Topic 326”) Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. This guidance also requires new disclosures for financial assets measured at amortized cost, loans, and available-for-sale debt securities. The Company adopted the standard as of the beginning of the Company’s fiscal year, February 1, 2020. The adoption of this guidance did not have a material impact to the co

No impairment loss has been recorded on the securities included in the tables above, as the Company believes that any decrease in fair value of these securities is temporary and the Company expects to recover at least up to the initial cost of the investment for these securities. The Company has not recorded an allowance for credit losses, as the Company believes any such losses would be immaterial based on the high-grade credit rating for each of our marketable securities as of the end of each period.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures its financial assets and liabilities at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value, as follows: Level 1—Valuations based on observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2—Valuations based on inputs that are directly or indirectly observable in the marketplace. Level 3—Valuations based on unobservable inputs that are supported by little or no market activity. The following table presents information about the Company’s financial assets that are required to be measured or disclosed at fair value using the above input categories: As of January 31, 2021 Level 1 Level 2 Level 3 Total (in thousands) Money market funds $ 139,870 $ — $ — $ 139,870 U.S. Treasury securities 14,988 45,026 — 60,014 Commercial paper — 34,598 — 34,598 Corporate debt securities — 141,488 — 141,488 Total $ 154,858 $ 221,112 $ — $ 375,970 Included in cash equivalents $ 154,858 Included in investments $ 221,112 As of January 31, 2020 Level 1 Level 2 Level 3 Total (in thousands) Money market funds $ 118,899 $ — $ — $ 118,899 U.S. Treasury securities 2,994 34,003 — 36,997 Commercial paper — 26,117 — 26,117 Corporate debt securities — 162,282 — 162,282 U.S. Government agency securities — 4,973 — 4,973 Total $ 121,893 $ 227,375 $ — $ 349,268 Included in cash equivalents $ 121,893 Included in investments $ 227,375 The Company’s assets that are measured by management at fair value on a recurring basis are classified within Level 1 or Level 2 of the fair value hierarchy. The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. As of January 31, 2021 and 2020, the Company’s Level 2 securities were priced by pricing vendors. These pricing vendors utilize observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs like market transactions involving identical or comparable securities. The carrying amounts of certain financial instruments, including cash held in banks, accounts receivable, and accounts payable approximate fair value due to their short-term maturities and are excluded from the fair value table above. Convertible Senior Notes As of January 31, 2021, the estimated fair value of the Notes was approximately $409.8 million. The fair value was determined based on the quoted price for the Notes in an inactive market on the last trading day of the reporting period and is considered as Level 2 in the fair value hierarchy.

Business Combinations	Business Combinations On October 1, 2020, the Company completed the acquisition of Rundeck Inc. (“Rundeck”), a leading provider of DevOps automation for enterprise. The acquisition of Rundeck strengthens the Company’s product and will enable the Company’s customers to resolve incidents faster, therefore reducing costs and protecting the customer experience. The Company acquired Rundeck for purchase consideration of $95.5 million in a combination of cash and common stock. The total purchase price consisted of the following: (in thousands) Cash paid or payable to common and preferred stockholders, warrant holders, and vested option holders (1) $ 51,741 Fair value of common stock transferred 34,002 Fair value of assumed options and restricted stock attributable to pre-combination service (2) 4,934 Fair value of future cash payments to common stockholders attributable to pre-combination service 4,808 Total purchase consideration $ 95,485 (1) Includes $0.2 million of payments related to a business acquisition, accrued but not yet paid. (2) The restricted shares are considered to be legally issued and outstanding on the date of issuance. The fair value of the stock and options recognized as purchase consideration was determined using the closing price of the Company’s common stock on the acquisition date. In addition to the purchase consideration, a portion of cash and stock for certain Rundeck key personnel attributable to post-combination services is subject to vest over two years from the closing of the acquisition, subject to on-going employee services and achievement of certain performance conditions as follow: • $3.7 million in future cash payments beginning in the fourth quarter of fiscal year 2021, which the Company will recognize within research and development over the vesting period of two years. • $3.3 million related to the fair value of restricted stock issued that will vest beginning from the acquisition date, which the Company will recognize as stock-based compensation expense over the vesting period of two years. The restricted shares are considered to be legally issued and outstanding on the date of issuance. • In connection with the acquisition, the Company incurred transaction costs of $1.8 million within the general and administrative line of the Consolidated Statements of Operations. The acquisition was accounted for as a business combination and the total purchase consideration was allocated to the net tangible and intangible assets and liabilities based on their fair values on the acquisition date and the excess was recorded as goodwill. The values assigned to the assets acquired and liabilities assumed are based on preliminary estimates of fair value available as of the date of this Annual Report on Form 10-K and may be adjusted during the measurement period of up to 12 months from the date of acquisition as further information becomes available. Any changes in the fair values of the assets acquired and liabilities assumed during the measurement period may result in adjustments to good will. As of January 31, 2021, the primary area that remains preliminary relates to the valuation of certain tax-related items. The following table presents the preliminary purchase consideration allocation recorded in the Company’s consolidated balance sheet as of the acquisition date: (in thousands) Cash and cash equivalents $ 1,925 Accounts receivable and other assets 1,879 Intangible assets 27,800 Goodwill 72,126 Accounts payable and other liabilities (548) Deferred revenue (2,680) Deferred tax liabilities, net (5,017) Total purchase consideration $ 95,485 The goodwill was primarily attributed to the value of synergies created with the Company’s current and future offerings. Goodwill is not deductible for income tax purposes. In connection with the acquisition, the Company recognized a net deferred tax liability for approximately $5.0 million, generated primarily from the difference between the tax basis and fair value of the acquired intangible assets, which increased goodwill. As the Company has a full valuation allowance as of January 31, 2021, the Company recorded an income tax benefit for this net deferred tax liability in the consolidated statement of operations for the year ended January 31, 2021. Refer to Note 13, "Income Taxes" , for further information. The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of acquisition: Fair Value Useful Life (in thousands) (in years) Customer relationships $ 21,800 10 Developed technology $ 5,600 5 Trademarks $ 400 2 The acquired intangible assets are primarily related to the Rundeck product and domain knowledge around customer data developed by Rundeck, and term license software subscription contracts with customers.

Leases [Abstract]
Leases	Leases Operating Leases The Company has entered into various non-cancellable operating leases for its office spaces with lease periods expiring between fiscal 2022 and fiscal 2029. The operating lease agreements generally provide for rental payments on a graduated basis and for options to renew, which could increase future minimum lease payments if exercised. Lease right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease right-of-use assets also include any lease payments made and exclude lease incentives such as tenant improvement allowances. The operating leases typically include non-lease components such as common-area maintenance costs. The Company has elected to include non-lease components with lease payments for the purpose of calculating lease right-of-use assets and liabilities, to the extent that they are fixed. Non-lease components that are not fixed are expensed as incurred as variable lease payments. Leases with a term of one year or less are not recognized on the consolidated balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The following tables present information about leases on the consolidated balance sheet. As of January 31, 2021 (in thousands) Assets Lease right-of-use assets $ 24,691 Liabilities Lease liabilities 5,262 Lease liabilities, non-current 26,542 As of January 31, 2021, the weighted average remaining lease term was 5.7 years and the weighted average discount rate used to determine the net present value of the lease liabilities was 3.7%.

Debt Disclosure [Abstract]
Debt and Financing Arrangements	Debt and Financing Arrangements Convertible Senior Notes On June 25, 2020, the Company issued $287.5 million in aggregate principal amount of the Notes in a private offering pursuant to an Indenture dated June 25, 2020 (the “Indenture”). The total net proceeds from the debt offering, after deducting initial purchaser discounts and debt issuance costs, paid or payable by the Company, were $278.2 million. The Notes are senior, unsecured obligations of the Company and will accrue interest payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2021, at a rate of 1.25% per year. The Notes will mature on July 1, 2025, unless such notes are converted, redeemed or repurchased earlier. The Notes are convertible into cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election in the manner and subject to the terms and conditions provided in the Indenture. Holders of the Notes may convert all or any portion of their Notes at their option at any time prior to the close of business on 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 the Company’s 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 on each applicable trading day; • During the five business day period after any ten consecutive trading day period (the measurement period) in which the “trading price” (as defined in the Indenture) per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; • If the Company calls such Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or • Upon the occurrence of specified corporate events, as noted in the Indenture. On or after April 1, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the Notes may convert all or any portion of their Notes at any time, regardless of the foregoing circumstances. The conversion rate will initially be 24.9507 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $40.08 per share of common stock. The conversion rate is subject to adjustment under certain circumstances in accordance with the terms of the Indenture, but will not be adjusted for accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such a fundamental change, as defined in the Indenture. The Company may not redeem the Notes prior to July 6, 2023. The Company may redeem for cash all or any portion of the Notes, at its option, on a redemption date occurring on or after July 6, 2023 and prior to the 41st scheduled trading day immediately preceding the maturity date, if the last reported sale price of the common stock has been at least 130% of the conversion price for the Notes 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 the Company provides notice of redemption at a redemption price equal to 100% of the principal amount to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Notes. If the Company undergoes a fundamental change (as defined in the Indenture), holders may require the Company to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding Notes may declare the entire principal of all the Notes plus accrued and unpaid interest to be immediately due and payable. In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated using a discount rate of 7.30%, which was determined by measuring the fair value of a similar debt instrument that does not have an associated conversion feature. The carrying amount of the equity component representing the conversion option was $70.8 million and was determined by deducting the fair value of the liability component from the par value of the Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification, and the equity component was recorded in additional paid-in-capital in the accompanying consolidated balance sheet. The excess of the principal amount of the liability component over its carrying amount, or the debt discount, is amortized to interest expense at an annual effective interest rate of 7.88% over the contractual terms of the Notes. The interest rate was based on the interest rate of similar liabilities at the time of issuance that did not have associated convertible features. The debt component is classified as a long-term liability as of January 31, 2021. In accounting for the issuance costs related to the Notes, the Company allocated the total amount incurred to the liability and equity components of the Notes based on their relative values. Issuance costs attributable to the liability component were $7.0 million and will be amortized to interest expense using the effective interest method over the contractual term of the Notes. Issuance costs attributable to the equity component were $2.3 million and were netted with the equity component in additional paid-in capital. The net carrying amount of the liability component of the Notes is as follows: As of January 31, 2021 (in thousands) Principal $ 287,500 Less: unamortized debt discount (63,664) Less: unamortized issuance costs (6,308) Net carrying amount $ 217,528 The net carrying amount of the equity component of the Notes is as follows: As of January 31, 2021 (in thousands) Proceeds allocated to the conversion options (debt discount) $ 70,768 Less: issuance costs (2,290) Carrying amount of the equity component $ 68,478 Interest expense recognized related to the Notes is as follows: Year Ended January 31, 2021 (in thousands) Contractual interest expense $ 2,157 Amortization of debt discount 7,104 Amortization of debt issuance costs 704 Total interest expense related to the Notes $ 9,965 Capped Call Transactions In connection with the offering of the Notes, the Company entered into privately negotiated capped call transactions (the “Capped Calls”) with certain financial institution counterparties (the “Option Counterparties”). The Capped Calls are generally intended to reduce or offset the potential dilution to the common stock upon any conversion of the Notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. For accounting purposes, the Capped Calls are separate transactions, and not part of the terms of the Notes. The Capped Calls are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $35.7 million incurred to purchase the Capped Calls were recorded as a reduction to additional paid-in capital in the accompanying consolidated balance sheet. The Capped Calls each have an initial strike price of approximately $40.08 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 $61.66 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, approximately 7.2 million shares of our common stock. The Capped Calls are subject to automatic exercise over a 40 trading day period commencing on May 2, 2025, subject to earlier termination under certain circumstances.

Equity Incentive Plans The Company has two equity incentive plans: the 2010 Stock Plan (the “2010 Plan”) and the 2019 Equity Incentive Plan (the “2019 Plan”, collectively the “Stock Plans”). Upon completion of the Company’s IPO in April 2019, the Company ceased granting awards under the 2010 Plan, and all shares that remained available for future issuance under the 2010 Plan at that time were transferred to the 2019 Plan. The 2019 Plan superseded and replaced the 2010 Plan. As of January 31, 2021 and January 31, 2020, respectively, the Company was authorized to grant up to 18,059,506 shares and 13,126,301 shares of common stock under the Stock Plans. In March 2019, the Company granted 3,041,000 stock options to existing employees with 50 percent of these options vesting over four years from the grant date and 50 percent vesting over five years from the grant date. The Company currently uses authorized and unissued shares to satisfy stock award exercises. As of January 31, 2021 and January 31, 2020, there were 13,060,282 shares and 11,841,156 shares available for future issuance under the Stock Plans, respectively.

The Company accounts for forfeitures as they occur. The following assumptions were used to calculate the fair value of employee stock option grants made during the periods: Year Ended January 31, 2021 2020 2019 Expected dividend yield — — — Expected volatility 43% - 44.1% 41.7% - 42.8% 40.1% - 43.2% Expected term (years) 3.7 - 6.1 5.5 - 6.9 5.4 - 6.8 Risk-free interest rate 0.20% - 0.52% 1.39% - 2.48% 2.53% - 3.04% Stock options granted during the fiscal years ended January 31, 2021, 2020, and 2019 had a weighted average grant date fair value of $15.16, $11.07, and $4.87 per share, respectively. The aggregate intrinsic value of stock options exercised during the fiscal years ended January 31, 2021, 2020, and 2019 was $72.1 million, $61.7 million, and $10.5 million, respectively. The intrinsic value for options exercised is the difference between the market value of the stock and the exercise price of the stock option at the date of exercise. As of January 31, 2021, there was approximately $32.3 million of total unrecognized compensation cost related to unvested stock options granted under the Stock Plans, which will be recognized over a weighted average period of 2.6 years.

The Company accounts for forfeitures as they occur. As of January 31, 2021, there was $86.9 million of unrecognized stock-based compensation expense related to unvested RSUs, which is expected to be recognized over a weighted average period of 3.3 years based on vesting under the award service conditions. In connection with the acquisition of Rundeck, the Company agreed to grant RSUs to Rundeck employees who joined the Company upon the effective date of the acquisition, with a value totaling approximately $14.6 million. The amount will be ratably recognized as stock-based compensation over the requisite service period of four years. Employee Stock Purchase Plan In April 2019, the Board adopted and approved the 2019 Employee Stock Purchase Plan, which became effective on April 11, 2019. The ESPP initially reserved and authorized the issuance of up to a total of 1,850,000 shares of common stock to participating employees. Pursuant to the terms of the ESPP, the number of shares reserved under the ESPP increased by 777,916 shares on February 1, 2020. The ESPP generally provides for 24-month offering periods beginning June 15 and December 15 of each year, with each offering period consisting of four six-month purchase periods, except for the initial offering period which began on April 11, 2019 and ended on December 13, 2019. On each purchase date, eligible employees will purchase the shares at a price per share equal to 85% of the lesser of (1) the fair market value of the Company’s stock as of the beginning of the offering period or (2) the fair market value of the Company’s stock on the purchase date, as defined in the ESPP. The following assumptions were used to calculate the fair value of shares to be granted under the ESPP during the periods: Year Ended January 31, 2021 2020 Expected dividend yield — — Expected volatility 39.2% - 61.6% 39.2% - 48.4% Expected term (years) 0.5 - 2.1 0.5 - 2.1 Risk-free interest rate 0.08% - 2.39% 1.53% - 2.43% During the fiscal years ended January 31, 2021 and 2020, the Company recognized $5.3 million and $5.1 million of stock-based compensation expense related to the ESPP, respectively, and withheld $6.2 million and $5.5 million in contributions from employees, respectively.

In June 2018, as part of this initiative, the Company issued to the Tides Foundation a warrant to purchase up to 648,092 shares of the Company’s common stock, exercisable at a price of $0.01 per share. The common stock warrant was automatically net exercised for 647,822 shares of common stock upon the closing of the IPO. The Company recognized $6.2 million of non-cash charitable contribution expense during the fiscal year ended January 31, 2019 and this amount is included within stock-based compensation expense in general and administrative expense in the accompanying consolidated statement of operations. Stock-Based Compensation Stock-based compensation expense included in the Company’s consolidated statements of operations is as follows: Year Ended January 31, 2021 2020 2019 (in thousands) Cost of revenue $ 1,702 $ 1,018 $ 282 Research and development 11,095 5,566 8,171 Sales and marketing (1) 14,733 8,924 3,982 General and administrative (2) 15,701 11,697 12,860 Total $ 43,231 $ 27,205 $ 25,295 (1) Stock-based compensation expense includes a one-time stock-based compensation expense of $3.1 million related to the modification of certain stock option awards in the fiscal year ended January 31, 2021.

Income Taxes	Income Taxes The components of loss before income taxes are as follows: Year Ended January 31, 2021 2020 2019 (in thousands) Domestic $ (77,956) $ (53,485) $ (39,863) Foreign 5,147 3,821 (177) Loss before (benefit from) provision for income taxes $ (72,809) $ (49,664) $ (40,040) The components of the (benefit from) provision for income taxes are as follows: Year Ended January 31, 2021 2020 2019 (in thousands) Current Federal $ — $ — $ — State (41) 126 26 Foreign 452 25 135 Total current tax expense $ 411 $ 151 $ 161 Deferred Federal $ (4,038) $ — $ (3) State (977) (1) — Foreign 698 525 543 Total deferred tax (benefit) expense $ (4,317) $ 524 $ 540 (Benefit from) provision for income taxes $ (3,906) $ 675 $ 701 A reconciliation of the Company’s recorded (benefit from) provision for income taxes to the amount of taxes computed at the U.S. statutory rate is as follows: Year Ended January 31, 2021 2020 2019 (in thousands) Income taxes computed at U.S. federal statutory rate $ (15,291) $ (10,429) $ (8,408) State taxes, net of federal benefit (5,012) (4,901) (1,326) Permanent differences 733 308 220 Stock-based compensation (8,557) (3,739) 1,077 Foreign rate differential (4) (239) 34 Uncertain tax positions 73 (14) 680 Tax credits (846) (3,271) — Change in valuation allowance 25,076 25,390 8,085 Charitable contributions — (1,960) — Other (78) (470) 339 (Benefit from) provision for income taxes $ (3,906) $ 675 $ 701 In fiscal 2021, the decrease to the Company's income tax provision relative to prior periods was primarily due to a reduction in the valuation allowance from the increase in the deferred tax liability associated with the acquired intangible assets from the acquisition of Rundeck, resulting in a $5.0 million deferred tax benefit. Deferred income taxes arise from temporary differences between the carrying values of assets and liabilities for financial reporting purposes and income tax reporting purposes, as well as operating losses and tax credit carryforwards. Significant components of the Company’s deferred tax assets and liabilities are as follows: As of January 31, 2021 2020 (in thousands) Deferred tax assets: Net operating losses $ 59,125 $ 36,412 Allowances and accruals 6,597 2,437 Stock-based compensation 7,990 5,523 Charitable contributions 3,988 3,989 Tax credits 6,631 5,349 Lease liabilities 8,096 — Other 677 2,075 Gross deferred tax assets $ 93,104 $ 55,785 Less: valuation allowance (57,944) (50,086) Net deferred tax assets $ 35,160 $ 5,699 Deferred tax liabilities: Convertible senior notes $ (15,450) $ — Deferred commissions (8,026) (6,519) Intangible assets (6,908) — Lease assets (6,274) — Other (277) (256) Gross deferred tax liabilities $ (36,935) $ (6,775) Net deferred tax liabilities $ (1,775) $ (1,076) The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods. The Company regularly assesses the ability to realize its deferred tax assets and establishes a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. The Company weighs all available positive and negative evidence, including its 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 its history of losses in the United States, the Company believes that it is more likely than not that its U.S. federal and state deferred tax assets will not be realized. Accordingly, the Company has recorded a full valuation allowance on such deferred tax assets. The valuation allowance against its various deferred tax assets increased by $7.9 million and $25.4 million during the fiscal years ended January 31, 2021 and 2020, respectively. As of January 31, 2021, the Company had federal net operating loss carryforwards in the amount of $234.3 million. Beginning in 2030, $56.3 million of the federal net operating losses will begin to expire. The remaining $178.0 million will carry forward indefinitely. As of January 31, 2021, the Company had state and foreign net operating loss carryforwards in the amount of $9.3 million, and $1.5 million, respectively, which begin to expire in 2031. Utilization of the Company’s net operating loss may be subject to annual limitations due to the ownership change limitations provided by section 382 of the Internal Revenue Code and similar state provisions. The Company’s net operating loss carryforwards could expire before utilization if subject to annual limitations. As of January 31, 2021, the Company had federal, California, and Canadian research and development credit carryforwards of $6.5 million, $4.6 million, and $0.4 million, respectively. The federal research and development credits will begin to expire in 2031, the California research and development credits have no expiration, and the Canadian research and development credits will begin to expire in 2037. The following table summarizes the activity related to the Company’s unrecognized tax benefits: Year Ended January 31, 2021 2020 2019 (in thousands) Balance at beginning of period $ 4,043 $ 6,644 $ 4,385 Additions related to prior years 29 71 — Reductions related to prior years (8) (3,515) (19) Additions related to current year 591 843 2,278 Additions related to acquired positions 363 — — Balance at end of period $ 5,018 $ 4,043 $ 6,644 All of the Company’s tax years remain open for examination by U.S. federal and state tax authorities. The non-U.S. tax returns remain open for examination for the years 2016 and onwards. Due to its U.S. federal and state valuation allowance, $1.0 million, $1.1 million, and $1.0 million of unrecognized tax benefits as of January 31, 2021, 2020, and 2019, respectively, would affect the effective tax rate if recognized. The Company recognizes interest and penalties related to unrecognized tax benefits as provision for income taxes. The Company has accrued an immaterial amount of interest and penalties associated with its unrecognized tax benefits noted above as of January 31, 2021, 2020, and 2019, respectively. The Company does not anticipate the total amounts of unrecognized tax benefits will significantly decrease in the next 12 months. U.S. income tax has not been recognized on the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries that is indefinitely reinvested outside the United States. As a result of the Tax Act, the tax impact of future distributions of foreign earnings would generally be limited to withholding tax from local jurisdictions. The amount of the deferred tax liability on the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries is not material.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the consolidated accounts of PagerDuty. All intercompany balances and transactions have been eliminated upon consolidation. The Company’s fiscal year ends on January 31. References to fiscal 2021, for example, refer to the fiscal year ended January 31, 2021.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make, on an ongoing basis, estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. The Company’s most significant estimates and judgments involve the valuation of the Company’s stock-based awards, including the determination of fair value of common stock (prior to the closing of the IPO) and the fair value of the employee stock purchase plan (“ESPP”) expense, period of benefit for amortizing deferred contract costs, the determination of the allowance for doubtful accounts, the provision for income taxes, including the related valuation allowance and any uncertain tax positions, fair value of the liability and equity components of the Convertible Senior Notes (the “Notes”), fair value of acquired assets and assumed liabilities, impairment of goodwill and intangible assets, the incremental borrowing rate for lease liabilities, and estimates related to our revenue recognition, such as the assessment of performance obligations in our revenue arrangements and the fair value assigned to each performance obligation, among others. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. In December 2019, the novel coronavirus and resulting disease (“COVID-19”) was reported and in March 2020 the World Health Organization declared it a pandemic. The extent of the impact of COVID-19 on our operational and financial performance will depend on certain developments, including the duration and spread of the outbreak, impact on our customers and our sales cycles, and impact on our employees, as discussed in more detail in the Overview section of our Management’s Discussion and Analysis. During the fiscal year ended January 31, 2021, this uncertainty resulted in a higher level of judgment related to our estimates and assumptions related to the estimate of credit losses for accounts receivable. As of the date of issuance of the financial statements, we are not
Segment Information	Segment Information The Company manages its operations and allocates resources as one operating segment. The Company’s chief operating decision maker (“CODM”) is its 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, Deferred Revenue, Deferred Contract Costs, and Cost of Revenue	Revenue Recognition The Company generates revenue primarily from cloud-hosted subscription fees with the majority of its revenue from such arrangements. The Company also generates an immaterial amount of revenue from term license software subscription fees. Revenue is recognized when control of these services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The Company accounts for revenue contracts with customers by applying the requirements of Topic 606, which includes the following steps: • Identification of the contract, or contracts, with a customer. • Identification of the performance obligations in the contract. • Determination of the transaction price. • Allocation of the transaction price to the performance obligations in the contract. • Recognition of revenue when, or as, the Company satisfies a performance obligation Cloud-hosted software subscriptions The Company’s cloud-hosted software subscriptions allow customers to use its cloud-hosted software over the contract period without taking possession of the software. The Company’s cloud-hosted software subscription agreements generally have monthly or annual contractual terms. Revenue related to our cloud-hosted software subscriptions is recognized ratably over the related contractual term beginning on the date that the Company’s platform is made available to a customer. Access to the platform represents a series of distinct services as the Company continually provides access to, and fulfills its obligation to, the end customer over the subscription term. The series of distinct services represents a single performance obligation that is satisfied over time. The Company recognizes revenue ratably because the customer receives and consumes the benefits of the platform throughout the contract period. Term license software subscriptions The Company’s term license software subscriptions provide both an obligation to provide access to its on-premise software, which includes both open source and proprietary features, as well as an obligation to provide support and maintenance. The Company’s term license software subscription agreements generally have annual contractual terms. The Company accounts for the license to the software and support as two separate performance obligations. As the open source software is publicly available at no cost to the customer, the Company has determined that there is no value to be assigned to the open source software in the term license software subscription arrangements. The proprietary software license represents a promise to provide a license to use functional intellectual property that is recognized at a point in time on the date access to the software is made available to the customer and the term license software subscription period has begun. The Company has concluded the support is a stand-ready performance obligation that consists of a series of distinct services that are satisfied ratably over time as the services are provided. The Company uses a time-based output method to measure progress because efforts are expended evenly throughout the period given the nature of the promise is a stand-ready service. The Company recognizes support revenue ratably, typically beginning on the start of the contractual term of the arrangement. In order to determine the stand-alone selling price, the Company conducts a periodic analysis that requires judgment and considers multiple factors that are reasonably available and maximizes the use of observable inputs that may vary over time depending upon the unique facts and circumstances related to each performance obligation. To have observable inputs, the Company requires that a substantial majority of the stand-alone selling prices for a product offering fall within a pricing range. The Company believes that this analysis results in an estimate that approximates the price that would be charged for the product offerings if they were sold separately. The Company’s cloud-hosted and term-license software subscription arrangements are generally non-cancellable and do not contain refund provisions. The Company bills for monthly cloud-hosted and term-license software subscriptions on a monthly basis and annually in advance for arrangements with terms of one year or more. The price of the cloud-hosted and term-license software subscriptions is generally fixed at contract inception and therefore, the Company’s contracts do not contain a significant amount of variable consideration. As a result, the amount of revenue recognized in the periods presented from performance obligations satisfied (or partially satisfied) in previous periods due to changes in the transaction price was not material. The Company’s revenue excludes sales and other indirect taxes. The Company records contract liabilities to deferred revenue when amounts are invoiced in advance of performance. Deferred revenue consists of the unearned portion of customer billings. The Company’s payment terms generally provide for payment within 30 days of the invoice date. Amounts anticipated to be recognized within one year of the balance sheet date are recorded as deferred revenue, current; the remaining portion is recorded as deferred revenue, non-current in the consolidated balance sheets. The Company applied the practical expedient in Topic 606 and did not evaluate contracts of one year or less for the existence of a significant financing component. For contracts with terms of more than a year, the Company has determined its contracts generally do not include a significant financing component as these all relate to contracts that are billed annually in advance. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s cloud- hosted software subscription, not to receive financing from its customers or to provide customers with financing. Deferred Contract Costs Deferred contract costs consist of sales commissions earned by the Company’s sales force which are considered incremental and recoverable costs of obtaining a contract with a customer. The Company determined that sales commissions that are related to contract renewals are not commensurate with commissions earned on the initial contract. Accordingly, sales commissions for initial contracts are deferred and then amortized on a straight-line basis over a period of benefit that the Company has determined to be four years. The Company determined the period of benefit by taking into consideration its customer contracts, technology, and other factors. Amounts anticipated to be recognized within one year of the balance sheet date are recorded as deferred contract costs, current; the remaining portion is recorded as deferred contract costs, noncurrent in the consolidated balance sheets. Deferred contract costs are periodically reviewed for impairment. Amortization of deferred contract costs is included in sales and marketing expense in the consolidated statements of operations.
Accounts Receivable and Related Allowance	Accounts Receivable and Related AllowanceAccounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based upon historical loss patterns, the age of each past due invoice, and an evaluation of the potential risk of loss associated with delinquent accounts. The allowance also reflects current market conditions and reasonable and supportable forecasts of future economic conditions. As of January 31, 2021, the allowance reflects considerations related to the COVID-19 pandemic and may increase in future periods as we ascertain future impacts to our customers and business.
Concentrations of Risk and Significant Customers	Concentrations of Risk and Significant Customers The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, held-to-maturity investments, available-for-sale investments, and accounts receivable. All of the Company’s cash and cash equivalents and investments are invested in money market funds, United States (“U.S.”) Treasury securities, commercial paper, corporate debt securities, or U.S. Government agency securities that management believes to be of high credit quality.
Foreign Currency Remeasurement	Foreign Currency RemeasurementThe functional currency of the Company’s international subsidiaries is the United States dollar. Accordingly, monetary balance sheet accounts are remeasured using exchange rates in effect at the balance sheet dates and non-monetary items are remeasured at historical exchange rates. Revenue and expenses are remeasured at the average exchange rates for the period.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents consist of cash on hand, highly liquid investments with original maturities of three months or less from the date of purchase, and money market funds.
Investments	Investments The Company’s investments are classified as available-for-sale and held-to-maturity and consist of highly liquid investments, primarily U.S. Treasury securities, commercial paper, corporate debt securities, and U.S. Government agency securities. The Company determines the appropriate classification of its investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company periodically evaluates its short-term investments to assess whether those with unrealized loss positions are impaired. The Company considers various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value is less than the Company’s cost basis, and the financial condition and near-term prospects of the investee. If the Company determines that the investment is impaired, an impairment loss is recognized in earnings equal to the difference between the investment’s amortized cost and fair value at such date. Realized gains and losses are reported in other income, net, in the consolidated statements of operations. No impairment charges have been recognized to date. Held-to-maturity The Company’s held-to-maturity investments consist of investments with maturities over three months from the date of purchase and less than 12 months from the date of the balance sheet and are classified as short-term. The Company has the ability and positive intent to hold these investments to maturity. Held-to-maturity investments are carried at amortized cost, which approximates fair value. Available-for-sale
Property and Equipment, Net	Property and Equipment, Net Property and equipment, net, are stated at cost less accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the respective assets, which is generally three
Research and Development Expense	Research and Development Expense Research and development expenses consist primarily of personnel costs for the Company’s engineering, product, and design teams. Additionally, research and development expenses include contractor fees, depreciation of equipment used in research and development activities, acquisition-related expenses, and allocated overhead costs. Research and development costs are expensed as incurred.
Internal-Use Software Costs	Internal-Use Software CostsThe Company evaluates costs related to the development of its platform and certain projects for internal use incurred during the application development stage. Costs related to preliminary project activities and post-implementation activities are expensed as incurred and costs related to the application development stage are capitalized. Internal-use software is amortized on a straight-line basis over its estimated useful life of three years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
Business Combinations	Business Combinations The Company applies the acquisition method of accounting for business combinations. Under this method of accounting, all assets acquired and liabilities assumed are recorded at their respective fair values at the date of the acquisition. The purchase consideration is allocated to the net tangible and identifiable intangible assets. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions. These estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable.
Goodwill and Acquired Intangible Assets	Goodwill. Goodwill represents the excess purchase consideration of an acquired business over the fair value of the net tangible and identifiable intangible assets. Goodwill is evaluated for impairment annually in the fourth quarter, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate or a significant decrease in expected cash flows. No impairment charges were recorded during the fiscal years ended January 31, 2021, 2020, or 2019. Acquired Intangible Assets. Acquired intangible assets consist of identifiable intangible assets, primarily developed technology and customer relationships, resulting from the Company’s business acquisition. Intangible assets are recorded at fair value on the date of acquisition and amortized over their estimated useful lives.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets. The carrying amounts of the Company’s long-lived assets, including property and equipment, lease right-of-use assets, capitalized internal-use software, and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful lives are shorter than originally estimated. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If long-lived assets are considered impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. If the Company reduces the estimated useful life assumption for any asset, the remaining unamortized balance would be amortized or depreciated over the revised estimated useful life.
Convertible Senior Notes	Convertible Senior Notes The Notes are accounted for in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Subtopic 470-20, Debt with Conversion and Other Options . Pursuant to ASC Subtopic 470-20, issuers of certain convertible debt instruments, such as the Notes, that have a net settlement feature and may be settled wholly or partially in cash upon conversion are required to separately account for the liability (debt) and equity (conversion option) components of the instrument. The carrying amount of the liability component of the instrument is computed by estimating the fair value of a similar liability without the conversion option using a market-based approach. The amount of the equity component is then calculated by deducting the fair value of the liability component from the principal amount of the instrument. The difference between the principal amount and the liability component represents a debt discount that is amortized to interest expense over the respective term of the Notes using the effective interest rate method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the issuance costs related to the Notes, the allocation of issuance costs incurred between the liability and equity components was based on their relative values.
Advertising Costs	Advertising CostsAdvertising costs are expensed as incurred and are included in sales and marketing expense.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for all stock-based payment awards, including stock options and restricted stock units (“RSUs”), based on the estimated fair value of the award on the grant date. The Company estimates the fair value of stock options issued to employees on the date of grant using the Black-Scholes option pricing model, which is impacted by the estimated fair value of the Company’s common stock, as well as certain assumptions including the expected volatility over the term of the option awards, the expected term of the awards, risk-free interest rates and the expected dividend yield. Assumptions and estimates used in the determination of the fair value of stock options are as follows: Expected volatility —Expected volatility is a measure of the amount by which the stock price is expected to fluctuate. Since the Company does not have sufficient trading history for its common stock, it estimates the expected volatility of its stock options by taking the average historical volatility of a group of comparable publicly traded companies over a period equal to the expected life of the options. Expected term —The Company determines the expected term based on the average period the stock options are expected to remain outstanding, generally calculated as the midpoint of the stock options’ vesting term and contractual expiration period, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior. Risk-free rate —The Company uses the U.S. Treasury yield for its risk-free interest rate that corresponds with the expected term. Expected dividend yield —The Company utilizes a dividend yield of zero, as it does not currently issue dividends and does not expect to in the future. Fair value of common stock Prior to the IPO, in accordance with the American Institute of Certified Public Accountants Accounting and Valuation Guide, Valuation of Privately-Held Company Equity Securities Issued as Compensation , the Company’s board of directors exercised reasonable judgment and considered numerous objective and subjective factors to determine the best estimate of fair value of the Company’s common stock, including but not limited to contemporaneous valuations of our common stock performed by independent third-party specialists; the prices, rights, preferences, and privileges of redeemable convertible preferred stock relative to those of common stock; the prices at which the Company sold shares of its common stock to third-party investors and in secondary transactions in arm’s-length transactions; the Company’s operating and financial performance; and additional relevant economic information. The Company estimates the fair value of RSUs at our stock price on the grant date. The Company estimates the fair value of shares to be issued under the ESPP on the first day of the offering period using the Black-Scholes valuation model, which is impacted by the estimated fair value of the Company’s common stock, as well as certain assumptions including the expected volatility over the term of the offering period, the expected term of the awards, risk-free interest rates and the expected dividend yield. Assumptions used in the determination of the fair value of the ESPP are the same as those used in the determination of the fair value of our stock options. The Company recognizes compensation expense for employee stock-based payment awards on a straight-line basis over the period during which an award recipient is required to provide services in exchange for the award (generally the vesting period of the award). The Company accounts for forfeitures as they occur. The fair value of each non-employee stock option is estimated at the date of grant using the Black-Scholes option pricing model and is not remeasured over the vesting term. Assumptions used in valuing non-employee stock options are generally consistent with those used for employee stock options with the exception that the expected term is over the contractual life.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, the Company recognizes deferred income tax assets and liabilities for the expected future consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as for net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. The Company recognizes the deferred income tax effects of a change in tax rates in the period of enactment. The Company records a valuation allowance to reduce its deferred tax assets to the net amount that it believes is more likely than not to be realized. The Company considers all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing tax planning strategies in assessing the need for a valuation allowance. Realization of its deferred tax assets is dependent primarily upon future U.S. taxable income.
Net Loss Per Common Share	Net Loss Per Common Share Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period giving effect to all potentially dilutive securities to the extent they are dilutive. The dilutive effect of potentially dilutive securities is reflected in diluted net loss per share by application of the treasury stock method. Basic and diluted net loss per common share were the same for each period presented as the inclusion of all potential common shares outstanding would have been anti-dilutive.
Recently Issued/Adopted Accounting Pronouncements	Recently Issued Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2020-06, Debt—Debt with Conversion Options (“Subtopic 470-20”) and Derivatives and Hedging—Contracts in Entity’s Own Equity (“Subtopic 815-40”) (“ASU 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity's own equity. ASU 2020-06 also improves and amends the related Earnings Per Share guidance for both Subtopics. The ASU is part of the FASB's simplification initiative, which aims to reduce unnecessary complexity in U.S. GAAP. ASU 2020-06 will be effective for annual reporting periods beginning after December 15, 2021. Early adoption is permitted, but not before annual reporting periods beginning after December 15, 2020. The Company will early adopt this ASU using the modified retrospective method beginning February 1, 2021. While the adoption remains in progress, the Company expects that the adoption will result in a decrease to our accumulated deficit as of February 1, 2021 related to the interest expense from the amortization of the debt discount. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (“Topic 842”) (“ASU 2016-0”2) , which would require lessees to recognize most leases on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to current practice. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The Company adopted the standard using the optional alternative method on a prospective basis with an effective date as of the beginning of the Company’s fiscal year, February 1, 2020, and applied it to the operating leases that existed on that date. Prior year comparative financial information was not recast under the new standard and continues to be presented under ASC 840. The Company elected to utilize the package of practical expedients available for expired or existing contracts which allowed the Company to carryforward historical assessments of (a) whether contracts are or contain leases, (b) lease classification, and (c) initial direct costs. The Company elected to apply the short-term lease exception for all leases. Under the short-term lease exception, the Company will not recognize right-of-use assets or lease liabilities for leases that, at the acquisition date, have a remaining lease term of 12 months or less. As a result of implementing this guidance, the Company recognized a net operating right-of-use asset of $29.1 million and a $35.9 million operating lease liability in its consolidated balance sheets as of February 1, 2020. The adoption of this guidance did not affect the Company’s consolidated statements of operations or consolidated statements of cash flows. Refer to Note 7, “Leases” for further information. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments—Credit Losses (“Topic 326”) Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. This guidance also requires new disclosures for financial assets measured at amortized cost, loans, and available-for-sale debt securities. The Company adopted the standard as of the beginning of the Company’s fiscal year, February 1, 2020. The adoption of this guidance did not have a material impact to the consolidated financial statements. In connection with the adoption, for purposes of identifying and measuring impairment, the policy election was made to exclude accrued interest from both the fair value and amortized cost basis of our available-for sale debt securities. Such accrued interest is recorded in prepaid expenses and other current assets. In January 2017, the FASB released Accounting Standards Update No. 2017-04, Intangibles— Goodwill and Other (“Topic 350”) (ASU 207-04”), which simplifies the subsequent measurement of goodwill, eliminating Step 2 from the goodwill impairment test. Previously, under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments of ASU 2017-04, an entity performs its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and an impairment charge would be recognized for any amount by which the carrying amount exceeds the reporting unit’s fair value.. The amendments in this update were effective for an entity’s annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or fiscal year 2021 for the Company. The Company performs their impairment test on goodwill in the fourth quarter of each fiscal year. In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (“Topic 820”) (“ASU 2018-13”), which modifies the disclosure requirements for fair value measurements for certain types of investments. The Company adopted this standard in the first quarter of fiscal year 2020. The adoption did not have an effect on the consolidated financial statements. In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (“Topic 740”): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which is intends to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for the Company beginning in fiscal 2022, although early adoption is permitted. The Company early adopted the standard as of the beginning of the Company’s fiscal year, February 1, 2020. The adoption of this guidance did not have a material impact to the consolidated financial statements.
Fair Value Measurements	The Company measures its financial assets and liabilities at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value, as follows: Level 1—Valuations based on observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2—Valuations based on inputs that are directly or indirectly observable in the marketplace. Level 3—Valuations based on unobservable inputs that are supported by little or no market activity.
