Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies New Relic, Inc. (the “Company” or “New Relic”) was incorporated in Delaware on February 20, 2008, when it converted from a Delaware limited liability company called New Relic Software, LLC, which was formed in Delaware in September 2007. The Company provides a strategic observability platform that enables users to collect, store and analyze vast quantities of telemetry data flowing from applications and infrastructure to monitor, troubleshoot, and optimize their software. Basis of Presentation —These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. 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 consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2020, as filed with the SEC on May 14, 2020 (the “Annual Report”). In the opinion of management, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, stockholders’ equity and cash flows for the interim period, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2021. The condensed consolidated balance sheet as of March 31, 2020 included herein was derived from the audited financial statements as of that date. Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Significant items subject to such estimates and assumptions include the fair value of share-based awards, fair value of purchased intangible assets and goodwill, fair value of debt and equity components related to the 0.5% convertible senior notes due 2023 (the “Notes”), useful lives of purchased intangible assets, unrecognized tax benefits, expected benefit period for deferred commissions, incremental borrowing rate used for operating lease liabilities, and the capitalization and estimated useful life of the Company’s software development costs. These estimates are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from management’s estimates. COVID-19 —The worldwide spread of COVID-19 has resulted in a global slowdown of economic activity that is expected to continue and which is likely to decrease demand for a broad variety of goods and services, while also disrupting sales channels and marketing activities for an unknown period of time until the disease is contained. The Company’s revenue and deferred revenue have been negatively impacted by the slowdown in activity associated with the COVID-19 pandemic for the fiscal year ending March 31, 2021, but at this point, the extent of the impact to the Company’s financial condition or results of operations is uncertain, particularly as the COVID-19 pandemic continues to persist for an extended period of time, and as of the date of issuance of these financial statements, management is not aware of any specific event or circumstance that would require an update to estimates and judgments or revising the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information is obtained, and will be 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 the financial statements. Concentration of Risk —There was no customer that represented more than 10% of the Company’s accounts receivable balance as of December 31, 2020 or March 31, 2020. There was no customer that individually exceeded 10% of the Company’s revenue during the three or nine months ended December 31, 2020 or 2019. Revenue Recognition —The Company generates revenue from subscription-based arrangements and usage-based arrangements that allow customers to access its products and/or platform. The Company determines revenue recognition through 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; and • recognition of revenue, when, or as, the Company satisfies a performance obligation. Revenue from subscription-based arrangements is recognized on a ratable basis over the contractual subscription period of the arrangement beginning when or as control of the promised goods or services is transferred to the customer. Beginning in the second quarter of fiscal 2021, the Company started offering usage-based pricing to its customers. Customers have the option to be charged upon their incurred usage in arrears (“Pay as You Go”), or they may commit to a minimum spend over their contracted period (“Annual Pool of Funds”). Revenue related to Pay as You Go contracts are recognized based on the customers’ actual usage. Revenue related to Annual Pool of Funds contracts are recognized on a ratable basis over the contract period including an estimate of the usage above the minimum commitment. The estimated usage-based revenues are constrained to the amount the Company expects to be entitled to receive in exchange for providing access to its platform. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) . This ASU simplifies the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. This will result in more convertible debt instruments being accounted for as a single liability instrument and more convertible preferred stock being accounted for as a single equity instrument with no separate accounting for embedded conversion features. The ASU also simplifies the diluted earnings per share (“EPS”) calculation in certain areas. This standard will be effective for the Company in the fiscal year beginning April 1, 2022; early adoption is permitted in the fiscal year beginning April 1, 2021. The Company has not yet adopted this new standard and is currently evaluating the effect the standard will have on its condensed consolidated financial statements. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities. The Company adopted this new standard on April 1, 2020. The adoption of this standard did not have a material impact on its condensed consolidated financial statements. Under the new standard, the Company assesses credit losses on accounts receivable by taking into consideration past collection experience, credit quality of the customer, age of the receivable balance, current economic conditions, and forecasts that affect the collectability of the reported amount. With respect to available-for-sale debt securities, the updated guidance requires that credit losses be presented as an allowance rather than as a write-down. Allowance for credit losses is recorded in other income (expense), net on the condensed consolidated statements of operations, limited by the amount that fair value is less than the amortized cost basis. Non-credit related impairment losses are reported as a separate component on the condensed consolidated statements of comprehensive loss. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which eliminates Step 2 from the goodwill impairment test. The Company adopted this standard on April 1, 2020. The adoption of this standard did not have a material impact on its condensed consolidated financial statements or disclosures. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which amends ASC 820, Fair Value Measurement. ASU 2018-13 modifies the In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740)

Business Combinations [Abstract]
Business Combinations	Business Combinations Pixie Labs Inc. On December 22, 2020, the Company acquired all of the equity interests in Pixie Labs Inc. (“Pixie Labs”), a company that provides a next-generation machine intelligence observability solution for developers using Kubernetes. The aggregate purchase price of $107.9 million consisted of approximately $45.6 million in cash (of which $15.0 million is being held in escrow for 12 months after the transaction closing date) and 884,269 shares of the Company’s common stock with an aggregate fair value of approximately $62.4 million. The fair value of the consideration transferred was determined based on a $70.53 per share price of the Company’s common stock. The total purchase price was allocated to the developed technology acquired with an estimated useful life of three years , net assets assumed, and a deferred tax liability related to the developed technology. The excess purchase price was recorded as goodwill, as set forth below. Goodwill generated from the acquisition is attributable to expected synergies from future growth and is not deductible for tax purposes. The following table presents the purchase price allocation related to the acquisition (in thousands): Cash consideration paid $ 45,558 Fair value of common shares 62,367 Total purchase price 107,925 Net assets assumed (4,099) Deferred tax liabilities 115 Developed technology acquired (4,800) Goodwill $ 99,141 The acquisition has been accounted for as a business combination. The direct transaction costs of the acquisition have been accounted for separately from the business combination and expensed as incurred. Total direct transaction costs incurred by the Company were $0.9 million, which were included in general and administrative expenses in the Company’s condensed consolidated statement of operations for the three and nine months ended December 31, 2020 . The Company paid $0.6 million in acquisition-related expenses incurred by Pixie Labs related to Pixie Labs’ advisors which were included as part of the purchase consideration. The business combination did not have a material impact on the condensed consolidated financial statements and therefore historical and proforma disclosures have not been presented. The acquisition also included a holdback arrangement with certain employees of Pixie Labs, totaling approximately 736,469 shares of the Company’s common stock, contingent upon their continued employment with the Company. The fair value of these awards, which are subject to the recipients’ continued service, was $51.9 million and was excluded from the aggregate purchase price. These awards will be recognized as stock-based compensation expense over the remaining vesting period which ranges from 18 months to 37 months. IOpipe, Inc. On October 31, 2019, the Company acquired certain assets of IOpipe, Inc., a company that provides monitoring tools for serverless applications, for $5.1 million in cash. The Company held back approximately $0.9 million from the aggregate purchase price which has been accrued as a liability. Of the total purchase price, $1.5 million was allocated to acquired technology with an estimated useful life of three years with the excess $3.6 million of the purchase price over the fair value of the intangible assets acquired recorded as goodwill. The acquisition has been accounted for as a business combination under the acquisition method. Goodwill and other intangibles generated from the acquisition are attributable to expected synergies from future growth and potential future monetization opportunities, and are deductible for tax purposes. The business combination did not have a material impact on the condensed consolidated financial statements and therefore historical and proforma disclosures have not been presented.

On August 21, 2018, the investors initially contributed approximately $3.6 million (396,000,000 Japanese Yen) in exchange for 40% of the outstanding common stock of New Relic K.K. On August 21, 2019, the Company and Investors additionally contributed approximately $1.5 million (156,000,000 Japanese Yen) and approximately $1.0 million (104,000,000 Japanese Yen), respectively, to subscribe to additional shares. As of December 31, 2020, the Company owned approximately 60% of the outstanding common stock in New Relic K.K. All of the common stock held by the Investors may be callable by the Company or puttable by the Investors upon certain contingent events. Should the call or put option be exercised, the redemption value would be determined based on a prescribed formula derived from the discrete revenues of New Relic K.K. and the Company and may be settled, at the Company’s discretion, with Company stock or cash. As a result of the put right available to the redeemable non-controlling interest holders in the future, the redeemable non-controlling interest in New Relic K.K. is classified outside of permanent equity in the Company’s consolidated balance sheet as of December 31, 2020, and the balance is reported at the greater of the initial carrying amount adjusted for the redeemable non-controlling interest’s share of earnings or losses, or its estimated redemption value. The resulting changes in the estimated redemption amount are recorded within retained earnings or, in the absence of retained earnings, additional paid-in-capital. The estimated redemption value of the call/put option embedded in the redeemable non-controlling interest was $0 at December 31, 2020. The following table summarizes the activity in the redeemable non-controlling interest for the periods indicated below: Nine Months Ended December 31, 2020 2019 Balance, beginning of period $ 1,669 $ 2,733 Investment by redeemable non-controlling interest — 978 Net loss attributable to redeemable non-controlling interest (1,059) (1,437) Balance, end of period $ 610 $ 2,274

Debt Disclosure [Abstract]
0.5% Convertible Senior Notes and Capped Call	0.5% Convertible Senior Notes and Capped Call In May 2018, the Company issued $500.25 million in aggregate principal amount of Notes in a private offering, including an additional $65.25 million aggregate principal amount of such notes pursuant to the exercise in full of the initial purchasers’ over-allotment option. The Notes are the Company’s senior unsecured obligations and bear interest at a fixed rate of 0.5% per annum, payable semi-annually in arrears on May 1 and November 1 of each year, commencing on November 1, 2018. The Notes will mature on May 1, 2023, unless earlier converted or repurchased. Each $1,000 principal amount of the Notes will initially be convertible into 9.02 shares of the Company’s common stock (the “Conversion Option”), which is equivalent to an initial conversion price of approximately $110.81 per share. The Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding November 1, 2022, only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ending on September 30, 2018 (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; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the indenture governing the Notes) 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 our common stock and the conversion rate for the Notes on each such trading day; or (3) upon the occurrence of specified corporate events as set forth in the indenture governing the Notes. On or after November 1, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. Upon conversion, the Company may satisfy its conversion obligation by paying and/or delivering, as the case may be, 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 governing the Notes. The conversion rate is subject to adjustment under certain circumstances in accordance with the terms of the indenture governing the Notes. In addition, following certain corporate events that occur prior to the maturity date, the Company will increase the conversion rate, in certain circumstances, for a holder who elects to convert its Notes in connection with such a corporate event. During the three and nine months ended December 31, 2020, the conditions allowing holders of the Notes to convert have not been met. The Notes were therefore not convertible during the three and nine months ended December 31, 2020 and were classified as long-term debt for such period. In accounting for the transaction, the Notes were separated into liability and equity components. The carrying amount of the liability component was calculated 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 $102.5 million and was determined by deducting the fair value of the liability component from the proceeds received upon issuance of the Notes. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Notes over the liability component (the “Debt Discount”) and the debt issuance costs are amortized to interest expense over the contractual term of the Notes at an effective interest rate of 5.74%. This rate is inclusive of the issuance costs. In accounting for the debt issuance costs of $11.6 million related to the Notes, the Company allocated the total amount incurred to the liability and equity components using the same proportions as the proceeds of the Notes. Issuance costs attributable to the liability component were $9.2 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 $2.4 million and netted with the equity component in additional paid-in capital. The net carrying amount of the liability component of the Notes was as follows (in thousands): December 31, 2020 March 31, 2020 Principal $ 500,250 $ 500,250 Unamortized debt discount (51,607) (66,894) Unamortized issuance costs (4,967) (6,312) Net carrying amount $ 443,676 $ 427,044 Interest expense related to the Notes was as follows (in thousands): Three Months Ended December 31, Nine Months Ended December 31, 2020 2019 2020 2019 Amortization of debt discount $ 5,162 $ 4,901 $ 15,287 $ 14,515 Amortization of issuance costs 460 413 1,345 1,203 Contractual interest expense 625 625 1,876 1,876 Total interest expense $ 6,247 $ 5,939 $ 18,508 $ 17,594 In connection with the offering of the Notes, the Company entered into privately negotiated capped call transactions with certain counterparties (the “Capped Calls”). The Capped Calls each have an initial strike price of approximately $110.81 per share, subject to certain adjustments, which correspond to the initial conversion price of the Notes. The Capped Calls have initial cap prices of $173.82 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, approximately 4.5 million shares of our common stock. Conditions that cause adjustments to the initial strike price of the Capped Calls mirror conditions that result in corresponding adjustments for the Notes. The Capped Calls are generally intended to reduce potential dilution to holders of the Company’s common stock upon any conversion of the Notes and/or offset any cash payments New Relic is required to make in excess of the principal amount of converted Notes, as the case may be, with such reduction and/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. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $63.2 million incurred in connection with the Capped Calls was recorded as a reduction to additional paid-in capital. The net impact related to stockholders’ equity has been included in additional paid-in capital and was a result of the issuance costs of $2.4 million and the purchase of capped calls noted above in the amount of $63.2 million.

Leases [Abstract]
Leases	Leases The Company leases office space under non-cancelable operating leases, which expire from 2021 to 2031. All of its office leases are classified as operating leases with lease expense recognized on a straight-line basis over the lease term. 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 these leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company considers information including, but not limited to, the lease term, the Company's credit rating and interest rates of similar debt instruments with comparable credit ratings. The lease right-of-use assets are also increased by any lease prepayments made and reduced by any lease incentives such as tenant improvement allowances. Options to extend the lease term are included in the lease term when it is reasonably certain that the Company will exercise the extension option. The Company’s operating leases typically include nonlease components such as common-area maintenance costs. The Company has elected to include nonlease components with lease payments for the purpose of calculating lease right-of-use assets and liabilities, to the extent that they are fixed. Nonlease 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 Company’s condensed consolidated balance sheet.

The ESPP initially reserved and authorized the issuance of up to 1,000,000 shares of common stock. The ESPP provides that the number of shares reserved and available for issuance under the ESPP automatically increases each April, beginning on April 1, 2015, by the lesser of 500,000 shares, 1% of the number of the Company’s common stock shares issued and outstanding on the immediately preceding March 31, or such lesser number of shares as determined by the Company’s board of directors. For the nine months ended December 31, 2020, 136,978 shares of common stock were purchased under the ESPP. For the nine months ended December 31, 2019, 117,115 shares of common stock were purchased under the ESPP.

Additionally, shares not issued or subject to outstanding grants under the 2008 Plan upon its termination became available under the 2014 Plan, resulting in a total of 5,184,878 available shares under the 2014 Plan as of the effective date of the 2014 Plan. Pursuant to the terms of the 2014 Plan, any shares subject to outstanding stock options or other stock awards under the 2008 Plan that (i) expire or terminate for any reason prior to exercise or settlement, (ii) are forfeited because of the failure to meet a contingency or condition required to vest such shares or otherwise return to the Company or (iii) are reacquired, withheld (or not issued) to satisfy a tax withholding obligation in connection with an award or to satisfy the purchase price or exercise price of a stock award will become available for issuance pursuant to awards granted under the 2014 Plan.

Revenue from Contract with Customer [Abstract]
Accounts Receivable, Deferred Revenue and Performance Obligations	Contract Acquisition CostsThe Company capitalizes certain contract acquisition costs primarily consisting of commissions. The balances of deferred costs to obtain customer contracts were $65.0 million and $60.2 million as of December 31, 2020 and March 31, 2020, respectively. In the three months ended December 31, 2020 and 2019, amortization from amounts capitalized was $9.7 million and $8.3 million, respectively. In the nine months ended December 31, 2020 and 2019, amortization from amounts capitalized was $28.2 million and $24.0 million, respectively. In the three months ended December 31, 2020 and 2019, amounts expensed as incurred were $4.4 million and $3.6 million, respectively. In the nine months ended December 31, 2020 and 2019, amounts expensed as incurred were $10.6 million and $8.2 million, respectively. The Company had no impairment loss in relation to costs capitalized.Accounts Receivable, Deferred Revenue and Performance Obligations In a response to the COVID-19 pandemic, the Company performed additional procedures to evaluate the creditworthiness of its customers and assess collectability of accounts. Using a current expected credit loss model, the Company determined that, while there may be a delay in collections due to the downturn in economic activity, there has not been a material impact to the risk of credit loss on accounts receivables as of December 31, 2020. The following table presents the changes to the Company’s deferred revenue (in thousands): Three Months Ended December 31, Nine Months Ended December 31, 2020 2019 2020 2019 Deferred revenue, beginning of period $ 275,598 $ 233,215 $ 316,327 $ 271,597 Billings 194,173 156,820 482,083 405,263 Revenue recognized (166,340) (153,028) (494,979) (439,853) Deferred revenue, end of period $ 303,431 $ 237,007 $ 303,431 $ 237,007 For the three and nine months ended December 31, 2020 and 2019, the majority of revenue recognized was from the deferred revenue balances at the beginning of each period. The aggregate unrecognized transaction price of remaining performance obligations as of December 31, 2020 was $648.3 million. The Company expects to recognize more than 91% of the balance as revenue in the 24 months following December 31, 2020 and the remainder thereafter. The aggregate balance of remaining performance obligations represents contracted revenue that has not yet been recognized and does not include contract amounts which are cancellable by the customer and amounts associated with optional renewal periods.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is subject to income tax in the United States as well as other tax jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income tax. The Company does not provide for federal income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are to be reinvested indefinitely. The Company recorded an income tax provision of $0.6 million and $0.9 million for the three months ended December 31, 2020 and 2019, respectively, and an income tax provision of $1.3 million and $1.5 million for the nine months ended December 31, 2020 and 2019, respectively, related to foreign income taxes, research tax credits, and the tax benefit from the acquisition of Pixie Labs related to the partial release of valuation allowance. Based on the available objective evidence during the three and nine months ended December 31, 2020, the Company believes it is more likely than not that the tax benefits of U.S. and Japan losses incurred during the three and nine months ended December 31, 2020 may not be realized. Accordingly, the Company did not record the tax benefits of U.S. and Japan losses incurred during the three and nine months ended December 31, 2020. The primary difference between the effective tax rate and the statutory tax rate relates to the valuation allowance on the U.S. and Japan losses, foreign tax rate differences, generation of research tax credits, and the tax benefit from the acquisition of Pixie Labs.

Net Loss Per Share

Net Loss Per Share	9 Months Ended

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per Share Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of employee share-based awards and warrants. Diluted net loss per share is computed giving effect to all potential dilutive common shares, including common stock issuable upon exercise of stock options and unvested restricted common stock. As the Company had net losses for each of the three and nine months ended December 31, 2020 and 2019, all potential common shares were determined to be anti-dilutive, resulting in basic and diluted net loss per share being equal. Additionally, the 4.5 million shares underlying the conversion option in the Notes were not considered in the calculation of diluted net loss per share as the effect would be anti-dilutive. The Notes were not convertible as of December 31, 2020. The Company expects to settle the principal amount of the Notes in cash and therefore will use the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The following table sets forth the computation of net loss per share, basic and diluted (in thousands, except per share amounts): Three Months Ended December 31, Nine Months Ended December 31, 2020 2019 2020 2019 Numerator: Net loss attributable to New Relic $ (53,626) $ (27,195) $ (130,933) $ (60,978) Denominator: Weighted average shares used to compute net loss per share, basic and diluted 61,209 58,733 60,562 58,352 Net loss attributable to New Relic per share—basic and diluted $ (0.88) $ (0.46) $ (2.16) $ (1.05) The following outstanding options, unvested shares, and ESPP shares were excluded (as common stock equivalents) from the computation of diluted net loss per common share for the periods presented as their effect would have been antidilutive (in thousands): As of December 31, 2020 2019 Options to purchase common stock 3,011 3,043 RSUs and PSUs 4,104 3,250 ESPP shares 144 132 7,259 6,425

Accounting Policies [Abstract]
Description of Business	New Relic, Inc. (the “Company” or “New Relic”) was incorporated in Delaware on February 20, 2008, when it converted from a Delaware limited liability company called New Relic Software, LLC, which was formed in Delaware in September 2007. The Company provides a strategic observability platform that enables users to collect, store and analyze vast quantities of telemetry data flowing from applications and infrastructure to monitor, troubleshoot, and optimize their software.
Basis of Presentation	Basis of Presentation —These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. 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 consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2020, as filed with the SEC on May 14, 2020 (the “Annual Report”). In the opinion of management, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, stockholders’ equity and cash flows for the interim period, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2021. The condensed consolidated balance sheet as of March 31, 2020 included herein was derived from the audited financial statements as of that date.
Use of Estimates and COVID-19	Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Significant items subject to such estimates and assumptions include the fair value of share-based awards, fair value of purchased intangible assets and goodwill, fair value of debt and equity components related to the 0.5% convertible senior notes due 2023 (the “Notes”), useful lives of purchased intangible assets, unrecognized tax benefits, expected benefit period for deferred commissions, incremental borrowing rate used for operating lease liabilities, and the capitalization and estimated useful life of the Company’s software development costs. These estimates are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from management’s estimates. COVID-19 —The worldwide spread of COVID-19 has resulted in a global slowdown of economic activity that is expected to continue and which is likely to decrease demand for a broad variety of goods and services, while also disrupting sales channels and marketing activities for an unknown period of time until the disease is contained. The Company’s revenue and deferred revenue have been negatively impacted by the slowdown in activity associated with the COVID-19 pandemic for the fiscal year ending March 31, 2021, but at this point, the extent of the impact to the Company’s financial condition or results of operations is uncertain, particularly as the COVID-19 pandemic continues to persist for an extended period of time, and as of the date of issuance of these financial statements, management is not aware of any specific event or circumstance that would require an update to estimates and judgments or revising the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information is obtained, and will be 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 the financial statements.
Concentration of Risk	Concentration of Risk —There was no customer that represented more than 10% of the Company’s accounts receivable balance as of December 31, 2020 or March 31, 2020. There was no customer that individually exceeded 10% of the Company’s revenue during the three or nine months ended December 31, 2020 or 2019.
Revenue Recognition	Revenue Recognition —The Company generates revenue from subscription-based arrangements and usage-based arrangements that allow customers to access its products and/or platform. The Company determines revenue recognition through 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; and • recognition of revenue, when, or as, the Company satisfies a performance obligation. Revenue from subscription-based arrangements is recognized on a ratable basis over the contractual subscription period of the arrangement beginning when or as control of the promised goods or services is transferred to the customer. Beginning in the second quarter of fiscal 2021, the Company started offering usage-based pricing to its customers. Customers have the option to be charged upon their incurred usage in arrears (“Pay as You Go”), or they may commit to a minimum spend over their contracted period (“Annual Pool of Funds”). Revenue related to Pay as You Go contracts are recognized based on the customers’ actual usage. Revenue related to Annual Pool of Funds contracts are recognized on a ratable basis over the contract period including an estimate of the usage above the minimum commitment. The estimated usage-based revenues are constrained to the amount the Company expects to be entitled to receive in exchange for providing access to its platform.
Recently Issued Accounting Pronouncements Not Yet Adopted and Recently Adopted Accounting Pronouncements	Recently Issued Accounting Pronouncements Not Yet Adopted In August 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) . This ASU simplifies the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. This will result in more convertible debt instruments being accounted for as a single liability instrument and more convertible preferred stock being accounted for as a single equity instrument with no separate accounting for embedded conversion features. The ASU also simplifies the diluted earnings per share (“EPS”) calculation in certain areas. This standard will be effective for the Company in the fiscal year beginning April 1, 2022; early adoption is permitted in the fiscal year beginning April 1, 2021. The Company has not yet adopted this new standard and is currently evaluating the effect the standard will have on its condensed consolidated financial statements. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities. The Company adopted this new standard on April 1, 2020. The adoption of this standard did not have a material impact on its condensed consolidated financial statements. Under the new standard, the Company assesses credit losses on accounts receivable by taking into consideration past collection experience, credit quality of the customer, age of the receivable balance, current economic conditions, and forecasts that affect the collectability of the reported amount. With respect to available-for-sale debt securities, the updated guidance requires that credit losses be presented as an allowance rather than as a write-down. Allowance for credit losses is recorded in other income (expense), net on the condensed consolidated statements of operations, limited by the amount that fair value is less than the amortized cost basis. Non-credit related impairment losses are reported as a separate component on the condensed consolidated statements of comprehensive loss. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which eliminates Step 2 from the goodwill impairment test. The Company adopted this standard on April 1, 2020. The adoption of this standard did not have a material impact on its condensed consolidated financial statements or disclosures. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which amends ASC 820, Fair Value Measurement. ASU 2018-13 modifies the In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740)
