Accounting Policies [Abstract]
Basis of Preparation and Summary of Significant Accounting Policies	Note 2. Basis of Preparation and Summary of Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial reporting and in accordance with Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete financial statements. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 that has been filed with the Securities and Exchange Commission (“SEC”). In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments that are necessary for a fair presentation of results for the interim periods presented. The results of operations for any interim period may not be indicative of results for the full fiscal year or any other subsequent period. There have been no changes in the Company’s significant accounting policies for the three and nine months ended December 31, 2018 as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 that has been filed with the SEC. New Accounting Pronouncements Adopted Effective April 1, 2018, the Company adopted the Financial Accounting Standards Board (“FASB”) standard update ASU 2014-09, “Revenue from Contracts with Customers,” (“Topic 606”) which provides a principles-based, five-step approach to measure and recognize revenue from contracts with customers. The adoption of this guidance did not have a material impact on the Company’s consolidated statement of operations, cash flows, and balance sheet as of the adoption date or for the three or nine months ended December 31, 2018. Additional information and disclosures required by this new standard are contained in “Note 4. Revenue Recognition,” to the Company’s consolidated financial statements. Effective April 1, 2018, the Company adopted the FASB standard update ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” which requires certain financial assets to be measured at fair value with changes in fair value recognized in the statement of operations. The adoption of this guidance did not have a material impact on the Company’s consolidated statement of operations, cash flows, and balance sheet as of the adoption date or for the three or nine months ended December 31, 2018. Additional information and disclosures required by this new standard are contained in “Note 5. Cash Equivalents, Marketable Securities, and Fair Value Measurements,” to the Company’s consolidated financial statements. On June 20, 2018, the FASB issued ASU 2018-07, “Compensation – Stock Compensation (“Topic 718”): Improvements to Nonemployee Share-Based Payment Accounting,” which simplifies the accounting for share-based payments granted to nonemployees for goods and services. ASU 2018-07 eliminated the previous guidance for accounting for share-based payments to nonemployees and expanded Topic 718 to include share-based payments transactions to nonemployees. ASU 2018-07 is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The adoption of ASU 2018-07 requires a modified retrospective transition approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year. The Company early adopted ASU 2018-07 on June 20, 2018. The adoption of this guidance did not have a material impact on the Company’s consolidated statements of operations, cash flows, and balance sheet as of the adoption date or for the three or nine months ended December 31, 2018. Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases.” The new guidance significantly impacts lessee accounting and financial statement disclosures. Specifically, this guidance requires lessees to identify arrangements that should be accounted for as leases. Under this guidance, for lease arrangements exceeding a one year term, a right-of-use asset and lease obligation is recorded by the lessee for all leases on the balance sheet, whether operating or financing, while the statement of operations includes lease expense for operating leases and amortization and interest expense for financing leases. The lease obligation amount recorded on the balance sheet at the date of adoption of this guidance must be calculated using the applicable incremental borrowing rate at the date of adoption. Leases with a term of one year or less will be accounted for similar to existing guidance for operating leases. The Company is currently in the process of evaluating its lease arrangements to determine the impact of ASU 2016-02 on its consolidated financial statements as well as updating processes and controls in order to adopt the new standard. This evaluation includes a review of the Company’s existing leasing arrangements on its facilities. In addition, the evaluation includes a review of the Company’s existing contracts with its suppliers and vendors to determine if these agreements contain an embedded lease. The Company currently expects that its lease commitments will be recognized as operating lease liabilities and right-of-use assets upon adoption, which will increase total assets and total liabilities that the Company reports on its consolidated balance sheet. ASU 2016-02 must be adopted using a modified retrospective approach for all leases existing at, or entered into after the date of initial adoption, with an option to elect to use certain transition relief. ASU 2016-02 will become effective for the Company on April 1, 2019.
