Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2021, the Company's effective tax rate was 69%. The Company reported a tax benefit on an overall pretax loss, with foreign entities reporting losses of $0.6 million. The effective tax rate for the three months ended March 31, 2021, was positively impacted by excess tax benefits on stock-based compensation. For the three months ended March 31, 2020, the Company's effective tax rate was 31%. The Company reported a tax benefit on overall pretax loss, with foreign entities reporting losses of $14.4 million. The effective tax rate for the three months ended March 31, 2020, was positively impacted by excess tax benefits on stock-based compensation and state income tax benefits on a domestic loss. The Company’s effective tax rate could fluctuate on a quarterly basis due to the occurrence of significant and unusual or infrequent items, such as vesting of stock-based compensation or foreign currency gains and losses. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. As of March 31, 2021, and December 31, 2020, the amount of unrecognized tax benefits for uncertain tax positions was $24.7 million and $24.3 million, respectively, excluding related liabilities for interest and penalties of $1.2 million as of March 31, 2021, and December 31, 2020. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $3.6 million, due to the settlement of various audits and the expiration of statutes of limitation.
