Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The computation of the provision for (benefit from) income taxes for interim periods is determined by applying the estimated annual effective tax rate to year-to-date earnings from recurring operations and adjusting for discrete tax items recorded in the period. The Company's ability to estimate the geographic mix of earnings is impacted by the relatively high-growth nature of the business, fluctuations of business operations by country, and implementation of tax planning strategies. The Company recorded an income tax benefit of $0.8 million and $0.3 million for the three months ended March 31, 2021 and 2020, respectively. The income tax benefit in the three months ended March 31, 2021 was primarily related to the excess tax benefits from stock-based compensation deductions in the United Kingdom, offset by withholding taxes in the U.S. and income tax expense from profitable foreign jurisdictions. In determining the need for a valuation allowance, the Company weighs both positive and negative evidence in the various jurisdictions in which it operates to determine whether it is more likely than not that its deferred tax assets are realizable. Accordingly, there is no valuation allowance in the foreign jurisdictions. A full valuation allowance has been established in the U.S. and no deferred tax assets and related tax benefits have been recognized in the condensed consolidated financial statements.
