Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Significant Accounting Policies The Company's significant accounting policies are discussed in the "Notes to Consolidated Financial Statements, Note 2. Summary of Significant Accounting Policies" in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2021. There have been no significant changes to these policies that have had a material impact on the Company's condensed consolidated financial statements and related notes, except as noted below. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-06, Debt—Debt with Conversion and Other Options (ASC 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (ASC 815-40). The FASB issued this ASU to simplify the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity's own equity. This ASU removes the separation models for convertible debt with a cash conversion feature and convertible instruments with a beneficial conversion feature. Convertible instruments that continue to be subject to separation models are (1) those with conversion options that are required to be accounted for as bifurcated derivatives and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. The ASU also requires the if-converted method to be applied for all convertible instruments when calculating earnings per share. For public business entities, these amendments are effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020. The Company adopted ASU 2020-06 effective January 1, 2022 using the modified retrospective method and therefore financial information for periods before January 1, 2022 were not impacted. Upon adoption of ASU 2020-06, the Company is no longer recording the conversion feature of its 0.75% Convertible Senior Notes due 2025 (the 2025 Notes) and its 0.00% Convertible Senior Notes due 2026 (the 2026 Notes and together with the 2025 Notes, the Notes) in equity. Instead, the Company combined the previously separated equity component with the liability component, which together is now classified as debt, thereby eliminating the subsequent amortization of the debt discount as interest expense. Similarly, the portion of issuance costs previously allocated to equity was reclassified to debt and amortized as interest expense. Adoption of ASU 2020-06 resulted in an increase in the carrying value of the Notes by approximately $288.9 million, of which $4.4 million is classified as a current portion of convertible senior notes, net, to reflect the full principal amount of the Notes outstanding, net of unamortized debt discount and issuance costs, a decrease in additional paid-in capital of approximately $318.8 million and temporary equity, convertible senior notes of approximately $4.4 million to remove the equity component separately recorded for the conversion option associated with the Notes and its allocated issuance costs, and a cumulative-effect adjustment of approximately $34.3 million to the beginning balance of accumulated deficit as of January 1, 2022. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC Topic 606, Revenue from Contracts with Customers. Historically, such assets and liabilities are recognized by the acquirer at fair value in accordance with Topic 805.The ASU is effective for interim and annual periods beginning after December 15, 2022, on a prospective basis, with early adoption permitted. The Company early adopted this standard effective January 1, 2022, and such adoption did not have a material impact on its condensed consolidated financial statements.
