Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION AND CONSOLIDATION The Company's fiscal year ends on March 31 of each calendar year. Each reference to a fiscal year in these notes to the condensed consolidated financial statements refers to the fiscal year ended March 31 of the calendar year indicated (for example, fiscal 2020 refers to the fiscal year ending March 31, 2020). The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on substantially the same basis as our annual consolidated financial statements for the fiscal year ended March 31, 2019 with the exception of new lease accounting guidance discussed in the recently adopted accounting principles section below. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the SEC, regarding interim financial reporting. In the opinion of the Company's management, these interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of our financial position, results of operations, and cash flows for the periods presented. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. The March 31, 2019 year-end condensed consolidated balance sheet data in this document were derived from audited consolidated financial statements and does not include all of the disclosures required by GAAP. These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended March 31, 2019 and notes thereto included in the Company's fiscal 2019 Annual Report on Form 10-K. The results of operations and cash flows for the interim periods included in these condensed consolidated financial statements are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. USE OF ESTIMATES The preparation of the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to bad debts, returns reserve for expected cancellations, fair value of and/or potential impairment of goodwill and intangible assets, capitalization of internally developed software, benefit period for deferred commissions, stock-based compensation, discount rate used to calculate operating lease liabilities, income and sales tax liabilities, convertible senior notes fair value, litigation, and other contingencies. The Company bases its estimates on known facts and circumstances, historical experience, and various other assumptions. Actual results could differ from those estimates under different assumptions or conditions. RECLASSIFICATIONS AND OTHER CHANGES Certain prior year amounts in the statements of cash flows have been reclassified to conform with current year presentation. SIGNIFICANT ACCOUNTING POLICIES The significant accounting policies used in preparation of these condensed consolidated financial statements are disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2019 filed with the SEC on May 21, 2019, and there have been no changes to the Company's significant accounting policies during the three and nine months ended December 31, 2019 except for the accounting policies described below that were updated as a result of adopting Accounting Standards Update ("ASU") 2016-02, Leases. All amounts and disclosures set forth herein are in compliance with this standard. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS Effective April 1, 2019, the Company adopted ASU No. 2016-02 (“ASU 2016-02”), Leases using the modified retrospective transition approach utilizing the effective date as the date of initial application. ASU 2016-02 establishes a new lease accounting model for leases, which requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet, but lease expense will be recognized on the income statement in a manner similar to previous requirements. Prior years presented have not been adjusted for ASU 2016-02 and continue to be reported in accordance with our historical accounting policy. The new standard provides a number of optional practical expedients in transition. The Company has elected certain practical expedients permitted under the new lease standard, which among other things, allows the carryforward of the historical lease classification. As a result, there was no impact to opening retained earnings. The new standard also provides a practical expedient for an entity’s ongoing accounting. The Company has elected such practical expedient to not separate lease and non-lease components for all leases. It also made an accounting policy election to not recognize right-of-use assets and lease liabilities on the balance sheet for leases with a term of 12 months or less and will recognize lease payments as an expense on a straight-line basis over the lease term. The adoption of the new lease standard resulted in the recognition of right-of-use assets and lease liabilities of approximately $20.0 million and $21.4 million, respectively, for existing operating leases. The Company does not have significant finance lease right-of-use assets or liabilities. The adoption of the new lease standard did not have a material impact on the Company's accumulated deficit as of April 1, 2019. For additional information on leases and the impact of the new lease standard, refer to Note 7. RECENT ACCOUNTING PRONOUNCEMENTS In December 2019, the Financial Accounting Standards Board (the "FASB") issued ASU 2019-02, Income Taxes (Topic 740), which enhances and simplifies various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, and interim-period accounting for enacted changes in tax law. The amendment will be effective for public companies with fiscal years beginning after December 15, 2020, which is fiscal 2022 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements. In November 2019, the FASB issued ASU 2019-08, Compensation - Stock Compensation (Topic 718). The amendment requires that an entity measure and classify share-based payment awards granted to a customer by applying the guidance in Topic 718. The amount recorded as a reduction of the transaction price is required to be measured on the basis of the grant-date fair value of the share-based payment award in accordance with Topic 718. The amendments in this update are effective for fiscal years beginning after December 15, 2019, which is fiscal 2021 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which makes modifications to disclosure requirements on fair value measurements. The amendment is effective for public companies with fiscal years beginning after December 15, 2019, which is fiscal 2021 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal Use Software (Subtopic 350-40), which reduces complexity for the accounting for costs of implementing a cloud computing service arrangement. The amendment is effective for public companies with fiscal years beginning after December 15, 2019, which is fiscal 2021 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements. In June 2016, the FASB issued ASU 2016‑13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets. The new model uses a forward‑looking expected loss method, which will generally result in earlier recognition of allowances for losses. In November 2018, the FASB issued ASU 2018‑19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which clarifies that receivables arising from operating leases are not within the scope of Topic 326, Financial Instruments—Credit Losses. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which clarifies treatment of certain credit losses. In May 2019, the FASB issued ASU 2019-05, Financial Instruments — Credit Losses (Topic 326): Targeted Transition Relief, which permits an entity, upon adoption of ASU 2016-13, to irrevocably elect the fair value option (on an instrument-by-instrument basis) for eligible financial assets measured at amortized cost basis. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which included various narrow-scope improvements and clarifications. In November 2019, FASB issued ASU No. 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). These ASUs are effective for annual and interim periods beginning after December 15, 2019, which is fiscal 2021 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.
