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 unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP), and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. The condensed consolidated balance sheet as of January 31, 2020 was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended January 31, 2020 , included in the Company’s Annual Report on Form 10-K, filed with the SEC. The condensed consolidated financial statements include the results of PagerDuty, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation. In the opinion of management, the information contained herein reflects all adjustments necessary for a fair presentation of the Company’s results of operations, financial position, cash flows, and statements of stockholders’ equity. The results of operations for the three months ended April 30, 2020 are not necessarily indicative of the results to be expected for the full year ending January 31, 2021 or for any other interim period, or for any future year. The Company’s fiscal year ends on January 31. References to fiscal 2021 , for example, refer to the fiscal year ended January 31, 2021 . Reclassification Certain reclassifications of prior period amounts have been made in the Company’s condensed consolidated statements of cash flows to conform to the current period presentation. The Company reclassified the bad debt expense line item to the other line item on the accompanying consolidated statements of cash flows. These reclassifications had no effect on the reported results of operations. 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, and the incremental borrowing rate for lease liabilities, 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 quarter, 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 condensed 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.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies 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. One customer accounted for 10% of the total accounts receivable balance as of April 30, 2020 . No single customer accounted for more than 10% of the total accounts receivable balance as of January 31, 2020 . No single customer represented 10% or more of revenue for the three months ended April 30, 2020 or 2019 . Segment Information The Company manages 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. See Note 13, “Geographic Information” for information regarding the Company's long-lived assets and revenue by geography. Significant Accounting Policies There have been no significant changes to our significant accounting policies as compared to those described in our Annual Report on Form 10-K for the fiscal year ended January 31, 2020 , other than as set forth below. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at the invoiced amount, net of allowance for doubtful accounts. The allowance 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 April 30, 2020 , our 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 $1.5 million and $0.8 million as of April 30, 2020 and January 31, 2020 . Recently Adopted Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases, (Topic 842) (ASU 2016-02) , 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 condensed consolidated balance sheets as of February 1, 2020. The adoption of this guidance did not affect our condensed consolidated statements of operations or our condensed consolidated statements of cash flows. See 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 condensed consolidated financial statements. 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. We adopted this standard in the first quarter of 2020. The adoption did not have an effect on our 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 condensed consolidated financial statements.

When evaluating investments for impairment, we review factors such as length of time and extent to which fair value has been below cost basis, the financial condition of the issuer and any changes thereto, and our intent to sell, or whether it is more likely than not we will be required to sell, the investment before recovery of the investment’s amortized cost. No impairment loss has been recorded on the securities included in the tables above, as we believe that any decrease in fair value of these securities is temporary and we expect to recover at least up to the initial cost of the investment for these securities. We have not recorded an allowance for credit losses, as we believe 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 Measurements

Fair Value Measurements	3 Months Ended
	Apr. 30, 2020
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 April 30, 2020 Level 1 Level 2 Level 3 Total (in thousands) Money market funds $ 120,395 $ — $ — $ 120,395 U.S. Treasury securities — 27,094 — 27,094 Commercial paper 550 11,914 — 12,464 Corporate debt securities — 167,344 — 167,344 U.S. Government agency securities — 5,000 — 5,000 Total $ 120,945 $ 211,352 $ — $ 332,297 Included in cash equivalents $ 120,945 Included in investments $ 211,352 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 generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company considers all highly liquid investments purchased with a remaining maturity of three months or less to be cash equivalents. As of April 30, 2020 and January 31, 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.

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 our leases do not provide an implicit rate, we use our 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. Our operating leases typically include non-lease components such as common-area maintenance costs. We have 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 our condensed consolidated balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term. The following tables present information about leases on our condensed consolidated balance sheet.

Equity [Abstract]
Common Stock and Stockholders' Equity	Common Stock and Stockholders’ Equity Redeemable Convertible Preferred Stock Immediately prior to the completion of the IPO in April 2019, all shares of redeemable convertible preferred stock then outstanding were converted into 41,273,345 shares of common stock on a one -to-one basis and then immediately reclassified into common stock. 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 April 30, 2020 and January 31, 2020 , respectively, the Company was authorized to grant up to 17,556,493 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 April 30, 2020 and January 31, 2020 , there were 13,831,235 shares and 11,841,156 shares available for future issuance under the Stock Plans, respectively. Shares of common stock reserved for future issuance are as follows: April 30, 2020 Outstanding stock options and unvested RSUs outstanding 16,779,058 Available for future stock option and RSU grants 13,831,235 Available for ESPP 2,417,141 Total common stock reserved at April 30, 2020 33,027,434 Stock Option Activity Stock option activity is as follows: Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (in thousands) Outstanding at January 31, 2020 14,498,045 $ 7.37 7.8 years $ 231,300 Granted 140,270 $ 15.89 Exercised (730,363 ) $ 2.55 Canceled (540,609 ) $ 10.54 Outstanding at April 30, 2020 13,367,343 $ 7.59 7.6 years $ 180,717 Vested as of April 30, 2020 7,421,194 $ 4.72 6.9 years $ 121,656 The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options on the date of grant. 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: Three Months Ended April 30, 2020 2019 Expected dividend yield — — Expected volatility 43.3 % 42.4% - 42.8% Expected term (years) 6.1 5.5 - 6.9 Risk-free interest rate 0.46% - 0.47% 2.32% - 2.48% Stock options granted during the three months ended April 30, 2020 and 2019 had a weighted average grant date fair value of $6.61 and $10.58 per share, respectively. The aggregate intrinsic value of stock options exercised during the three months ended April 30, 2020 and 2019 was $11.5 million and $19.9 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 April 30, 2020 , there was approximately $41.3 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 3.1 years . Restricted Stock Units A summary of the Company’s RSU activity and related information is as follow: Number of RSUs Weighted Average Grant Date Fair Value Per Share Outstanding at January 31, 2020 1,114,911 $ 28.10 Granted 2,326,489 $ 15.89 Vested, net of shares withheld for employee payroll taxes (3,039 ) $ 24.88 Canceled (26,646 ) $ 28.45 Outstanding at April 30, 2020 3,411,715 $ 19.78 The Company uses the fair value of RSUs based on the fair value of the underlying shares on the date of grant. The Company accounts for forfeitures as they occur. As of April 30, 2020 , there was $62.7 million of unrecognized stock-based compensation expense related to unvested RSUs, which is expected to be recognized over a weighted average period of 3.7 years based on vesting under the award service conditions. Employee Stock Purchase Plan In April 2019, the Board adopted and approved the 2019 Employee Stock Purchase Plan (ESPP), 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, 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. During the three months ended April 30, 2020 and 2019 , the Company recognized $1.6 million and $0.4 million of stock-based compensation expense related to ESPP, respectively. During the three months ended April 30, 2020 , the Company withheld $1.9 million in contributions from employees. No contributions were withheld on behalf of employees for a future purchase during the three months ended April 30, 2019 due to the timing of payroll deductions. There were no purchases for the three months ended April 30, 2020 and 2019 related to the ESPP. Stock-Based Compensation Stock-based compensation expense included in the Company’s condensed consolidated statements of operations is as follows: Three Months Ended April 30, 2020 2019 (in thousands) Cost of revenue $ 344 $ 143 Research and development 2,183 860 Sales and marketing 2,285 1,464 General and administrative 3,496 2,345 Total $ 8,308 $ 4,812

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's provision for income taxes for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period. The Company's quarterly tax provision, and estimate of its annual effective tax rate, is subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income (or loss) relates, changes in how the Company does business, and tax law developments. The Company's estimated effective tax rate for the year differs from the U.S. statutory rate of 21% as a result of our U.S. losses for which no benefit will be realized, as well as our foreign operations which are subject to tax rates that differ from those in the U.S. The Company recorded an income tax expense of $0.2 million and $0.2 million for the three months ended April 30, 2020 and 2019

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP), and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. The condensed consolidated balance sheet as of January 31, 2020 was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended January 31, 2020 , included in the Company’s Annual Report on Form 10-K, filed with the SEC. The condensed consolidated financial statements include the results of PagerDuty, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation. In the opinion of management, the information contained herein reflects all adjustments necessary for a fair presentation of the Company’s results of operations, financial position, cash flows, and statements of stockholders’ equity. The results of operations for the three months ended April 30, 2020 are not necessarily indicative of the results to be expected for the full year ending January 31, 2021 or for any other interim period, or for any future year. The Company’s fiscal year ends on January 31. References to fiscal 2021 , for example, refer to the fiscal year ended January 31, 2021 .
Reclassification	Reclassification Certain reclassifications of prior period amounts have been made in the Company’s condensed consolidated statements of cash flows to conform to the current period presentation. The Company reclassified the bad debt expense line item to the other line item on the accompanying consolidated statements of cash flows. These reclassifications had no effect on the reported results of operations.
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, and the incremental borrowing rate for lease liabilities, 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.
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.

Recently Adopted/Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases, (Topic 842) (ASU 2016-02) , 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 condensed consolidated balance sheets as of February 1, 2020. The adoption of this guidance did not affect our condensed consolidated statements of operations or our condensed consolidated statements of cash flows. See 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 condensed consolidated financial statements. 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. We adopted this standard in the first quarter of 2020. The adoption did not have an effect on our 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 condensed 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.
Operating 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 our leases do not provide an implicit rate, we use our 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. Our operating leases typically include non-lease components such as common-area maintenance costs. We have 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 our condensed consolidated balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term.
