Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation — The unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries prepared in conformity with GAAP. All intercompany balances and transactions have been eliminated in consolidation and certain immaterial prior year amounts have been reclassified consistent with current year presentation. All amounts are in millions, except share and per share amounts and are approximate due to rounding.
Use of Estimates	Use of Estimates — The preparation of 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 revenues and expenses during the reporting period. Actual results could differ from these estimates and such differences could be material.
Foreign Currency	Foreign Currency — The nature of business activities involves the management of various financial and market risks, including those related to changes in foreign currency exchange rates. The functional currency of our operating subsidiaries outside the U.S. is the applicable local currency. For those operations, assets and liabilities are translated into U.S. dollars at period-end exchange rates and revenues and expenses are translated into U.S. dollars using average monthly exchange rates.
Emerging Growth Company	Emerging Growth Company (“EGC”) — Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”) exempts EGCs from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act of 1933, as amended, registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an EGC, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company, which is neither an EGC nor an EGC which has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used. As of June 30, 2021, our aggregate worldwide market value of voting and non-voting common equity held by non-affiliates exceeded $700 million. As we meet all other applicable criteria in the Securities Exchange Act of 1934, as amended, we anticipate that we will lose EGC status and become a large accelerated filer as of December 31, 2021.
Recently Adopted Accounting Standards and Recently Issued Accounting Standards	Recently Adopted Accounting Standards — On January 1, 2021, we adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC 842”), which requires an entity to recognize a right-of-use asset and lease liability for all leases with terms of more than twelve months and recognize expense over the lease term. We elected to transition to ASC 842 using the modified retrospective method. Prior period amounts are not adjusted and continue to be reported in accordance with historic accounting under previous lease guidance, ASC Topic 840, Leases (“ASC 840”). We elected to use the package of practical expedients permitted under the transition guidance. We did not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases, or (iii) initial direct costs for any existing leases. For lease agreements that include lease and non-lease components, we elected to use the practical expedient on all leases entered into or modified after January 1, 2021 to combine lease and non-lease components for all classes of assets. Additionally, we elected to not record on the balance sheet leases with a term of twelve months or less. Adopting ASC 842 did not result in a material impact to our financial statements and disclosures. Refer to Note 12, “Leases” for further detail. Recently Issued Accounting Standards — In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which amends the FASB’s guidance on the impairment of financial instruments. ASU 2016-13 adds to GAAP an impairment model (known as the “current expected credit loss model”) that is based on expected losses rather than incurred losses. ASU 2016-13 was originally effective for annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years. We will adopt ASU 2016-13 on January 1, 2022. We are currently evaluating the impact that this new guidance will have on our financial position, results of operations, cash flows and related disclosures.
