Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company calculates its interim income tax provision in accordance with ASC Topics 270, Interim Reporting, and 740, Income Taxes. At the end of each interim period, the Company makes an estimate of the annual U.S. domestic and foreign jurisdictions’ expected effective tax rates and applies these rates to its respective year to date taxable income or loss. The computation of the estimated effective tax rates at each interim period requires certain estimates and assumptions including, but not limited to, the expected operating income for the fiscal year, projections of the proportion of income (or loss) earned and taxed in the U.S. and foreign tax jurisdictions, along with permanent differences, and the likelihood of deferred tax asset utilization. The Company’s estimates and assumptions may change as new events occur, additional information is obtained, or as the tax environment changes. Should facts and circumstances change during a period causing a material change to the estimated effective income tax rate, a cumulative adjustment will be recorded. The income tax provisions for the three months ended September 30, 2021 and 2020 were based on the estimated annual effective income tax rates adjusted for discrete items occurring during the periods presented. For the three months ended September 30, 2021 and 2020, the Company recognized an aggregate consolidated income tax expense of $4,223 and $10,705, respectively, for U.S. domestic and foreign income taxes. For the three months ended September 30, 2021 and 2020, the Company recorded a discrete tax benefit of $6,724 and $3,826, respectively, associated with stock‑based compensation. The effective income tax rate was (9.3)% on Loss before income taxes of $45,241 for the three months ended September 30, 2021, as compared to the effective income tax rate of 62.5% on Income before income taxes of $17,130 for the three months ended September 30, 2020. For the three months ended September 30, 2021, the Company recognized a compensation charge of $90,721 to Deferred compensation plan expenses to record its reallocated deferred compensation plan liabilities at fair value (see Note 12). The effective income tax rate of (9.3)% for the three months ended September 30, 2021 was primarily due to the loss before income taxes resulting from this compensation charge, combined with a significant reduction in associated tax benefits due to officer compensation limitation provisions relating to this charge. The effective income tax rate of 62.5% for the three months ended September 30, 2020 was primarily due to officer compensation limitation provisions resulting from the Company’s IPO, which went effective during the three months ended September 30, 2020, and the non‑deductibility of expenses associated with the Company’s IPO, partially offset by discrete windfall tax benefits from stock‑based compensation. The income tax provisions for the nine months ended September 30, 2021 and 2020 were based on the estimated annual effective income tax rates adjusted for discrete items occurring during the periods presented. For the nine months ended September 30, 2021 and 2020, the Company recognized an aggregate consolidated income tax (benefit) expense of $(6,165) and $22,145, respectively, for U.S. domestic and foreign income taxes. For the nine months ended September 30, 2021 and 2020, the Company recorded a discrete tax benefit of $55,102 and $10,511, respectively, associated with stock‑based compensation. The effective income tax rate of (12.7)% on Income before income taxes of $48,562 for the nine months ended September 30, 2021 was lower than the effective income tax rate of 22.6% on Income before income taxes of $98,181 for the nine months ended September 30, 2020 primarily due to discrete windfall tax benefits from stock‑based compensation, partially offset by the impact from officer compensation limitation provisions.
