BASIS OF PRESENTATION AND CONSOLIDATION The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Accordingly, certain information and disclosures normally included in the Company's annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. 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, 2023 and notes thereto included in the Form 10-K. There were no material changes during the three and nine months ended December 31, 2023 to the Company's significant accounting policies as described in the Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company conducts its operations through one reportable segment. In the opinion of the Company's management, these condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the Company's financial position, results of operations and cash flows for the periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending March 31, 2024. The results of operations for the three and nine months ended December 31, 2022 have been reclassified to conform to the Company's current period presentation. During the three months ended December 31, 2022, the Company reclassified $3.7 million impairment of capitalized software from research and development expenses to impairment of long-lived assets. During the nine months ended December 31, 2022, the company reclassified $3.7 million impairment of capitalized software from research and development expenses and $2.4 million impairment of right-of-use assets from general and administrative expenses to impairment of long-lived assets. The prior period reclassifications had no impact on our condensed consolidated balance sheets, statements of comprehensive loss, statements of stockholders' equity and cash flows. USE OF ESTIMATES The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity, disclosure of contingent assets and liabilities at the date of the 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 current expected credit losses, returns reserve for expected cancellations, fair value of and/or potential impairment of goodwill and value and useful life of long-lived assets (including intangible assets and right-of-use assets), capitalized internal-use software costs, benefit period for deferred commissions, stock-based compensation, incremental borrowing 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. Impairment of Long-Lived Assets During the third quarter of fiscal year 2024, in support of the Company's office-home hybrid workforce model, the Company's board of directors authorized the cessation of use of approximately 42% of leased space at the Company’s headquarters at 675 Creekside Way, Campbell, CA (the “Company’s Headquarters”). The Company ceased use of the space on November 2, 2023, and plans to continue to hold this space available for sublease. Additionally, the Company partially ceased use of office space for a certain international lease and does not plan to hold this available for sublease. The Company reviewed the recoverability of the related right-of-use asset and determined the changes in the intended use of these locations represented an impairment indicator, as these events indicated the carrying value of the right-of-use asset may not be recoverable. In connection with partially ceasing use of the Company’s Headquarters and an international office space, the Company recorded impairment charges of $9.9 million and $1.1 million, respectively, as the carrying amount of the right-of-use assets related to the leases exceeded its fair value based on the Company’s estimate of future discounted cash flows under the income approach. The fair value represented a Level 3 measurement and utilized certain unobservable inputs which required significant judgment and estimates, including estimated sublease income, temporary idling periods, discount rates and future cash flows based on the Company’s experience and assessment of existing market conditions. During the three and nine months ended December 31, 2023, the non-cash charge of $11.0 million was recorded as an impairment of long-lived assets on the condensed consolidated statements of operations and consisted of an $11.0 million impairment of operating lease right-of-use assets. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS There were no recent accounting pronouncements that were applicable to the Company adopted during the nine months ended December 31, 2023. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an annual and interim basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact that this guidance will have on the presentation of its condensed consolidated financial statements and accompanying notes. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands disclosures in an entity’s income tax rate reconciliation table and disclosures regarding cash taxes paid both in the U.S. and foreign jurisdictions. The update will be effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact that this guidance will have on the presentation of its condensed consolidated financial statements and accompanying notes.
