Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Description of Business —New Relic, Inc. (the “Company” or “New Relic”) was incorporated in Delaware on February 20, 2008 . The Company is a software-as-a-service provider of digital intelligence products which allow users to monitor software and infrastructure performance and measure end user activities across desktop and mobile devices with applications deployed in a cloud or in a data center. New Relic’s digital intelligence products and platform capabilities enable software developers, IT operations, and business users to better understand their digital business. 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, 2016, as filed with the SEC on May 26, 2016 (the “Annual Report”). There have been no changes to the Company’s significant accounting policies described in the Annual Report that have had a material impact on its condensed consolidated financial statements and related notes. 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 and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2017. The condensed consolidated balance sheet as of March 31, 2016 included herein was derived from the audited financial statements as of that date. Use of Estimates —The preparation of the Company’s condensed 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 condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates. Concentration of Risk —There were no customers that represented more than 10% of the Company’s accounts receivable balance as of December 31, 2016 or March 31, 2016 . There were no customers that individually exceeded 10% of the Company’s revenue during the three and nine months ended December 31, 2016 or 2015 . Short-term Investments —Short-term investments consist of commercial paper, certificates of deposit, U.S. treasury securities, U.S. agency securities, and corporate notes and bonds and are classified as available-for-sale securities. The Company has classified its investments as current based on the nature of the investments and their availability for use in current operations. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of accumulated other comprehensive income, while realized gains and losses are reported within the statement of operations. The Company reviews its debt securities classified as short-term investments on a regular basis to evaluate whether or not any security has experienced an other-than-temporary decline in fair value. The Company considers factors such as the length of time and extent to which the market value has been less than the cost, the financial position and near-term prospects of the issuer, and the Company’s intent to sell, or whether it is more likely than not the Company will be required to sell the investment before recovery of the investment’s amortized-cost basis. If the Company determines that an other-than-temporary decline exists in one of these securities, the respective investment would be written down to fair value. For debt securities, the portion of the write-down related to credit loss would be recognized to other income, net in the condensed consolidated statement of operations. Any portion not related to credit loss would be included in accumulated other comprehensive income (loss). There were no impairments considered other-than-temporary as of December 31, 2016 and March 31, 2016 . Business Combinations —The Company recognizes identifiable assets acquired and liabilities assumed at their acquisition date fair value. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that the Company identifies adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statements of operations. There has been no such adjustment as of December 31, 2016 . Goodwill —Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets. Goodwill is evaluated for impairment annually in the third quarter of the Company’s fiscal year, 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 that could affect the value of goodwill or a significant decrease in expected cash flows. Since inception through December 31, 2016 , the Company did not have any goodwill impairment. Intangible Assets —Intangible assets consist of identifiable intangible assets, primarily developed technology, resulting from the Company’s acquisitions. Acquired intangible assets are recorded at cost, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives. Recent Accounting Pronouncements —In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The guidance allows for the use of either the full or modified retrospective transition method, and the standard will be effective for the Company in its fiscal year beginning April 1, 2018; early adoption is permitted for the fiscal year beginning April 1, 2017. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements, as well as which transition method the Company intends to use. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which requires lessees to put most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. ASU 2016-02 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 new standard will be effective for the Company in the fiscal year beginning April 1, 2019; early adoption is permitted. The amendments require a modified retrospective approach with optional practical expedients. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements. In March 2016, the FASB Issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The updated guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The update to the standard is effective for the Company in the fiscal year beginning April 1, 2017. The Company is currently evaluating the effect the standard will have on its condensed consolidated financial statements. 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 updated guidance requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statement of income. The update to the standard is effective for the Company in the fiscal year beginning April 1, 2020; early adoption is permitted in the fiscal year beginning April 1, 2019. The Company is currently evaluating the effect the standard will have on its condensed consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents in the statements of cash flows. This standard is effective for the Company in the fiscal year beginning April 1, 2018; early adoption is permitted. Adoption will be applied on a retrospective basis to all periods presented. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements.

Business Combinations [Abstract]
Business Combination	Business Combination In October 2015, the Company completed the acquisition of Opsmatic, Inc. (“Opsmatic”), a provider of live-state server configuration monitoring across dynamic cloud infrastructure, pursuant to which the Company acquired all of the capital stock of Opsmatic for $5.5 million in cash, up to 161,116 shares of the Company’s common stock, a portion of which are subject to forfeiture in the event of certain indemnification claims by the Company, and 12,008 restricted stock units (“RSUs”) with fair values of $39.15 per share, resulting in an aggregate purchase price of $12.3 million . Of the total purchase price, $2.5 million was allocated to acquired technology and an immaterial amount to net assets acquired, with the excess $9.8 million of the purchase price over the fair value of net tangible and intangible assets acquired recorded as goodwill. The Opsmatic technology complements the Company’s existing server and infrastructure monitoring capabilities. The acquisition has been accounted for as a business combination under the acquisition method. Goodwill generated from the acquisition is attributable to expected synergies from future growth and potential future monetization opportunities, and is not deductible for tax purposes. Pro forma revenue and results of operations have not been presented because the historical results of Opsmatic were not material to the Company’s condensed consolidated financial statements in any period presented. The acquisition also included an obligation to issue up to 98,115 shares of the Company's common stock, with an aggregate grant date fair value of $3.8 million , to certain employees of Opsmatic, contingent upon their continuous employment with the Company. As such, compensation expense is being recorded on a straight-line basis over the requisite service period of 30 months . As of December 31, 2016 , 69,291 of these shares were issued, 35,913 of which were subject to repurchase by the Company.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases —The Company leases office space under non-cancelable operating lease agreements, which expire from 2017 through 2023 . Deferred Rent —Certain of the Company’s operating leases contain rent holidays, allowances, and rent escalation provisions. For these leases, the Company recognizes the related rental expense on a straight-line basis over the life of the lease from the date the Company takes possession of the office and records the difference between amounts charged to operations and amounts paid as deferred rent. These rent holidays, allowances, and rent escalations are considered in determining the straight-line expense to be recorded over the lease term. As of December 31, 2016 and March 31, 2016 , $9.4 million and $5.1 million was recorded as deferred rent, respectively. Rent expense, net of sublease income, for operating leases was $2.4 million and $1.7 million for the three months ended December 31, 2016 and 2015 , respectively, and $7.3 million and $4.7 million for the nine months ended December 31, 2016 and 2015 , respectively. Future minimum lease payments under non-cancelable operating leases as of December 31, 2016 were as follows (in thousands): Years Ending March 31, Operating Leases 2017 (remaining 3 months) $ 2,558 2018 10,252 2019 10,446 2020 10,736 2021 7,606 Thereafter 15,681 Total minimum future lease payments $ 57,279 Purchase Commitments —As of December 31, 2016 and March 31, 2016 , the Company had purchase commitments of $24.9 million and $11.9 million , respectively, for specific contractual services. Legal Proceedings —From time to time, the Company may become involved in various legal proceedings in the ordinary course of its business, and may be subject to third-party infringement claims. On November 5, 2012, CA, Inc. filed suit against the Company in the United States District Court, Eastern District of New York for alleged patent infringement. CA, Inc.’s complaint against the Company claims that certain aspects of the Company’s products infringe certain patents held by CA, Inc. Discovery is complete in the case, and the court has ruled on summary judgment motions filed by both parties. A trial date has not been set as of December 31, 2016 . The Company cannot at this time predict the likely outcome of this proceeding or estimate the amount or range of loss or possible loss that may arise from it. The Company has not accrued any loss related to the outcome of this case as of December 31, 2016 . In the normal course of business, the Company may agree to indemnify third parties with whom it enters into contractual relationships, including customers, lessors, and parties to other transactions with the Company, with respect to certain matters. The Company has agreed, under certain conditions, to hold these third parties harmless against specified losses, such as those arising from a breach of representations or covenants, other third-party claims that the Company’s products when used for their intended purposes infringe the intellectual property rights of such other third parties, or other claims made against certain parties. To date, the Company has not incurred any costs as a result of such obligations and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements. In addition, the Company indemnifies its officers, directors, and certain key employees while they are serving in good faith in their respective capacities. The Company does not currently believe there is a reasonable possibility that a loss may have been incurred under these indemnification obligations. To date, there have been no claims under any such indemnification provisions.

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 will automatically increase 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. The first offering period under the ESPP commenced on August 15, 2015. For each of the three months ended December 31, 2016 and 2015 , no shares of common stock were purchased under the ESPP. For the nine months ended December 31, 2016 , 118,658 shares of common stock were purchased under the ESPP. For the nine months ended December 31, 2015 , no shares of common stock were purchased under the ESPP. Stock-based compensation expense recognized related to the ESPP was $0.5 million and $0.3 million for the three months ended December 31, 2016 and 2015 , respectively, and $1.4 million and $0.5 million for the nine months ended December 31, 2016 and 2015 , respectively. As of December 31, 2016 , there were 1,741,172 shares available for issuance under the ESPP. 2008 Equity Incentive Plan —The Company’s board of directors adopted the 2008 Equity Incentive Plan (the “2008 Plan”) in February 2008. The 2008 Plan was terminated in connection with the Company’s initial public offering (“IPO”), and accordingly, no shares are available for future issuance under this plan. The 2008 Plan continues to govern outstanding awards granted thereunder. 2014 Equity Incentive Plan —The Company’s board of directors adopted, and the Company’s stockholders approved, the Company’s 2014 Equity Incentive Plan (the “2014 Plan”), which became effective in December 2014. The 2014 Plan serves as the successor to the Company’s 2008 Plan. The 2014 Plan initially reserved and authorized the issuance of 5,000,000 shares of the Company’s common stock. 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. The 2014 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each April 1, beginning on April 1, 2015, by 5% of the outstanding number of shares 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. As of December 31, 2016 , there were 8,084,490 shares available for issuance under the 2014 Plan.

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 expected to be reinvested indefinitely. The Company recorded an income tax benefit of $37,000 and an income tax provision of $0.1 million for the three months ended December 31, 2016 and 2015 , respectively, and an income tax provision of $23,000 and $0.2 million for the nine months ended December 31, 2016 and 2015 , respectively, related to foreign income taxes and state minimum taxes. Based on the available objective evidence during the three and nine months ended December 31, 2016 , the Company believes it is more likely than not that the tax benefits of the U.S. losses incurred during the three and nine months ended December 31, 2016 may not be realized. Accordingly, the Company recorded a full valuation allowance against the tax benefits of the U.S. losses incurred during the three and nine months ended December 31, 2016 . The primary difference between the effective tax rate and the local statutory tax rate relates to the valuation allowance on the Company’s U.S. losses, foreign tax rate differences, and amortization of a deferred charge associated with the intercompany transfer of intellectual property from prior periods.

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per Share Basic 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 common 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, 2016 and 2015 , all potential common shares were determined to be anti-dilutive. 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, 2016 2015 2016 2015 Numerator: Net loss $ (13,883 ) $ (18,355 ) $ (46,084 ) $ (48,293 ) Denominator: Weighted average shares used to compute net loss per share, basic and diluted 52,328 48,953 51,297 48,001 Net loss per share—basic and diluted $ (0.27 ) $ (0.37 ) $ (0.90 ) $ (1.01 ) 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, 2016 2015 Options to purchase common stock 4,931 7,577 Common stock reserved for issuance in connection with acquisition 43 90 Restricted stock units 2,080 1,501 ESPP shares 104 67 7,158 9,235

Description of Business and Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Description of Business	Description of Business —New Relic, Inc. (the “Company” or “New Relic”) was incorporated in Delaware on February 20, 2008 . The Company is a software-as-a-service provider of digital intelligence products which allow users to monitor software and infrastructure performance and measure end user activities across desktop and mobile devices with applications deployed in a cloud or in a data center. New Relic’s digital intelligence products and platform capabilities enable software developers, IT operations, and business users to better understand their digital business.
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, 2016, as filed with the SEC on May 26, 2016 (the “Annual Report”). There have been no changes to the Company’s significant accounting policies described in the Annual Report that have had a material impact on its condensed consolidated financial statements and related notes. 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 and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2017. The condensed consolidated balance sheet as of March 31, 2016 included herein was derived from the audited financial statements as of that date.
Use of Estimates	Use of Estimates —The preparation of the Company’s condensed 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 condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates.
Concentration of Risk	Concentration of Risk —There were no customers that represented more than 10% of the Company’s accounts receivable balance as of December 31, 2016 or March 31, 2016 . There were no customers that individually exceeded 10% of the Company’s revenue during the three and nine months ended December 31, 2016 or 2015 .
Short-term Investments	Short-term Investments —Short-term investments consist of commercial paper, certificates of deposit, U.S. treasury securities, U.S. agency securities, and corporate notes and bonds and are classified as available-for-sale securities. The Company has classified its investments as current based on the nature of the investments and their availability for use in current operations. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of accumulated other comprehensive income, while realized gains and losses are reported within the statement of operations. The Company reviews its debt securities classified as short-term investments on a regular basis to evaluate whether or not any security has experienced an other-than-temporary decline in fair value. The Company considers factors such as the length of time and extent to which the market value has been less than the cost, the financial position and near-term prospects of the issuer, and the Company’s intent to sell, or whether it is more likely than not the Company will be required to sell the investment before recovery of the investment’s amortized-cost basis. If the Company determines that an other-than-temporary decline exists in one of these securities, the respective investment would be written down to fair value. For debt securities, the portion of the write-down related to credit loss would be recognized to other income, net in the condensed consolidated statement of operations. Any portion not related to credit loss would be included in accumulated other comprehensive income (loss). There were no impairments considered other-than-temporary as of December 31, 2016 and March 31, 2016 .
Business Combinations	Business Combinations —The Company recognizes identifiable assets acquired and liabilities assumed at their acquisition date fair value. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that the Company identifies adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statements of operations. There has been no such adjustment as of December 31, 2016 .
Goodwill	Goodwill —Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets. Goodwill is evaluated for impairment annually in the third quarter of the Company’s fiscal year, 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 that could affect the value of goodwill or a significant decrease in expected cash flows. Since inception through December 31, 2016 , the Company did not have any goodwill impairment.
Intangible Assets	Intangible Assets —Intangible assets consist of identifiable intangible assets, primarily developed technology, resulting from the Company’s acquisitions. Acquired intangible assets are recorded at cost, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives.
Recent Accounting Pronouncements	Recent Accounting Pronouncements —In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The guidance allows for the use of either the full or modified retrospective transition method, and the standard will be effective for the Company in its fiscal year beginning April 1, 2018; early adoption is permitted for the fiscal year beginning April 1, 2017. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements, as well as which transition method the Company intends to use. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which requires lessees to put most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. ASU 2016-02 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 new standard will be effective for the Company in the fiscal year beginning April 1, 2019; early adoption is permitted. The amendments require a modified retrospective approach with optional practical expedients. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements. In March 2016, the FASB Issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The updated guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The update to the standard is effective for the Company in the fiscal year beginning April 1, 2017. The Company is currently evaluating the effect the standard will have on its condensed consolidated financial statements. 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 updated guidance requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statement of income. The update to the standard is effective for the Company in the fiscal year beginning April 1, 2020; early adoption is permitted in the fiscal year beginning April 1, 2019. The Company is currently evaluating the effect the standard will have on its condensed consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents in the statements of cash flows. This standard is effective for the Company in the fiscal year beginning April 1, 2018; early adoption is permitted. Adoption will be applied on a retrospective basis to all periods presented. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements
