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 founded in 2007 and incorporated in Delaware on February 20, 2008 . The Company is a software-as-a-service provider of digital intelligence products that allow users to monitor software and infrastructure performance and measure end-user activities across desktop and mobile devices with applications deployed in the 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, 2017, as filed with the SEC on May 18, 2017 (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, 2018. The condensed consolidated balance sheet as of March 31, 2017 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 September 30, 2017 . One customer represented 12% of the Company’s accounts receivable balance as of March 31, 2017 . There were no customers that individually exceeded 10% of the Company’s revenue during the three and six months ended September 30, 2017 or 2016 . Short-term Investments —Short-term investments consist of commercial paper, certificates of deposit, U.S. treasury securities, U.S. agency securities, and corporate debt securities 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 as 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). The Company did not identify any investments as other-than-temporarily impaired as of September 30, 2017 and March 31, 2017 . 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 a 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 September 30, 2017 . 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 September 30, 2017 , the Company has not had 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 ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance provides principles for recognizing revenue to which an entity expects to be entitled for the transfer of promised goods or services to customers. The new guidance will be effective for the Company in its fiscal year beginning April 1, 2018. The guidance may be applied retrospectively to each prior period presented (full retrospective method), or with the cumulative effect recognized as of the date of initial adoption (modified retrospective method). The Company currently intends to adopt Topic 606 using the modified retrospective approach in the first quarter of fiscal year 2019. As the Company continues to assess the new standard along with industry trends and internal progress, the Company may adjust its implementation plan accordingly. The Company anticipates that the significant impacts of adopting Topic 606 will include the deferral of incremental commission costs of obtaining contracts and additional disclosure requirements. Currently, the Company records commissions as sales and marketing expenses as incurred. Under the new standard, the Company will capitalize incremental commissions related to initial contracts over the expected period of benefit. The Company has not yet concluded the amortization period of these capitalized costs, which will affect the classification and magnitude of the deferred costs at each reporting period. The Company will continue to quantify the effects of adopting Topic 606 on its condensed consolidated financial statements, including the impact on its revenue as well as the changes discussed above. 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 Company adopted this standard in the first quarter of fiscal year 2018. Upon adoption, the Company recognized all of the previously unrecognized excess tax benefits related to stock awards using the modified retrospective transition method. These excess tax benefits, recognized upon adoption, were recorded as a deferred tax asset, which was then fully offset by the U.S. federal and state deferred tax asset valuation allowance resulting in no impact to the accumulated deficit. Without the valuation allowance, the Company’s deferred tax asset would have increased by $39.5 million . All future excess tax benefits resulting from the settlement of stock awards will be recorded to the income tax provision. 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 will be 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 May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements. The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. The new guidance will be effective for the Company in its fiscal year beginning April 1, 2018. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements.

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 2027 . 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 September 30, 2017 and March 31, 2017 , $8.8 million and $9.2 million was recorded as deferred rent, respectively. Rent expense, net of sublease income, for operating leases was $2.7 million and $2.5 million for the three months ended September 30, 2017 and 2016 , respectively, and $5.3 million and $4.9 million for the six months ended September 30, 2017 and 2016 , respectively. Future minimum lease payments under non-cancelable operating leases as of September 30, 2017 were as follows (in thousands): Fiscal Years Ending March 31, Operating Leases 2018 (remaining 6 months) $ 5,648 2019 11,775 2020 12,972 2021 9,856 2022 8,321 Thereafter 22,280 Total minimum future lease payments $ 70,852 Purchase Commitments —As of September 30, 2017 and March 31, 2017 , the Company had purchase commitments of $25.7 million and $29.9 million , respectively, primarily related to hosting 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 September 30, 2017 . 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 September 30, 2017 . 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.

Equity [Abstract]
Common Stock and Stockholders' Equity	Common Stock and Stockholders’ Equity Employee Stock Purchase Plan —The Company’s board of directors adopted, and the Company’s stockholders approved, the Company’s 2014 Employee Stock Purchase Plan (the “ESPP”), which became effective in December 2014. 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 each of the three and six months ended September 30, 2017 , 101,493 shares of common stock were purchased under the ESPP. For each of the three and six months ended September 30, 2016 , 118,658 shares of common stock were purchased under the ESPP. Stock-based compensation expense recognized related to the ESPP was $0.6 million and $0.4 million for the three months ended September 30, 2017 and 2016 , respectively, and $1 million and $0.9 million for the six months ended September 30, 2017 and 2016 , respectively. As of September 30, 2017 , there were 2,046,251 shares available for issuance under the ESPP. 2008 Equity Incentive Plan —The Company’s board of directors adopted, and the Company’s stockholders approved, 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 automatically increases 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 September 30, 2017 , there were 9,889,781 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 provision of $0.2 million and an income tax benefit $0.1 million for the three months ended September 30, 2017 and 2016 , respectively, and an income tax provision of $0.4 million and $0.1 million for the six months ended September 30, 2017 and 2016 , respectively, related to foreign income taxes and state minimum taxes. Based on the available objective evidence during the three and six months ended September 30, 2017 , the Company believes it is more likely than not that the tax benefits of the U.S. losses incurred during the three and six months ended September 30, 2017 may not be realized. Accordingly, the Company did not record the tax benefits of U.S. losses incurred during the three and six months ended September 30, 2017 . 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 six months ended September 30, 2017 and 2016 , all potential common shares were determined to be anti-dilutive, resulting in basic and diluted net loss per share being equal. The following table sets forth the computation of net loss per share, basic and diluted (in thousands, except per share amounts): Three Months Ended September 30, Six Months Ended September 30, 2017 2016 2017 2016 Numerator: Net loss $ (14,691 ) $ (14,130 ) $ (30,625 ) $ (32,201 ) Denominator: Weighted average shares used to compute net loss per share, basic and diluted 54,699 51,328 54,201 50,779 Net loss per share—basic and diluted $ (0.27 ) $ (0.28 ) $ (0.57 ) $ (0.63 ) 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 September 30, 2017 2016 Options to purchase common stock 3,594 5,491 Restricted stock units 2,180 2,159 Common stock reserved for issuance in connection with acquisition 43 90 ESPP shares 41 36 5,858 7,776

Description of Business and Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Description of Business	Description of Business —New Relic, Inc. (the “Company” or “New Relic”) was founded in 2007 and incorporated in Delaware on February 20, 2008 . The Company is a software-as-a-service provider of digital intelligence products that allow users to monitor software and infrastructure performance and measure end-user activities across desktop and mobile devices with applications deployed in the 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, 2017, as filed with the SEC on May 18, 2017 (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, 2018. The condensed consolidated balance sheet as of March 31, 2017 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 September 30, 2017 . One customer represented 12% of the Company’s accounts receivable balance as of March 31, 2017 . There were no customers that individually exceeded 10% of the Company’s revenue during the three and six months ended September 30, 2017 or 2016 .
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 debt securities 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 as 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). The Company did not identify any investments as other-than-temporarily impaired as of September 30, 2017 and March 31, 2017 .
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 a 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 September 30, 2017 .
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 September 30, 2017 , the Company has not had 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 ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance provides principles for recognizing revenue to which an entity expects to be entitled for the transfer of promised goods or services to customers. The new guidance will be effective for the Company in its fiscal year beginning April 1, 2018. The guidance may be applied retrospectively to each prior period presented (full retrospective method), or with the cumulative effect recognized as of the date of initial adoption (modified retrospective method). The Company currently intends to adopt Topic 606 using the modified retrospective approach in the first quarter of fiscal year 2019. As the Company continues to assess the new standard along with industry trends and internal progress, the Company may adjust its implementation plan accordingly. The Company anticipates that the significant impacts of adopting Topic 606 will include the deferral of incremental commission costs of obtaining contracts and additional disclosure requirements. Currently, the Company records commissions as sales and marketing expenses as incurred. Under the new standard, the Company will capitalize incremental commissions related to initial contracts over the expected period of benefit. The Company has not yet concluded the amortization period of these capitalized costs, which will affect the classification and magnitude of the deferred costs at each reporting period. The Company will continue to quantify the effects of adopting Topic 606 on its condensed consolidated financial statements, including the impact on its revenue as well as the changes discussed above. 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 Company adopted this standard in the first quarter of fiscal year 2018. Upon adoption, the Company recognized all of the previously unrecognized excess tax benefits related to stock awards using the modified retrospective transition method. These excess tax benefits, recognized upon adoption, were recorded as a deferred tax asset, which was then fully offset by the U.S. federal and state deferred tax asset valuation allowance resulting in no impact to the accumulated deficit. Without the valuation allowance, the Company’s deferred tax asset would have increased by $39.5 million . All future excess tax benefits resulting from the settlement of stock awards will be recorded to the income tax provision. 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 will be 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 May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements. The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. The new guidance will be effective for the Company in its fiscal year beginning April 1, 2018. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements.
