Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company's quarterly tax provision and estimates of its annual effective tax rate are estimates due to several factors, including changes in pre-tax income (or loss), the mix of jurisdictions to which such income relates, discrete items (such as excess tax benefits from stock-based compensation) in the period offset with our valuation allowance. The (benefit from) income taxes was $(9.9) million and $(0.1) million for the three months ended September 30, 2021 and 2020, respectively. The $9.8 million decrease in tax expense resulted primarily from $11.7 million related to a pre-tax loss in jurisdictions where we expect to realize a tax benefit in the future, offset by an increase in tax expense of $1.9 million from profitable foreign jurisdictions. For the nine months ended September 30, 2021 and 2020, the (benefit from) provision for income taxes was $(7.7) million and $3.9 million, respectively. The $11.6 million benefit in tax expense resulted primarily from $11.7 million related to a pre-tax loss in a foreign jurisdiction where we expect to realize a tax benefit in the future
