Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate was (6.6)% (a tax benefit of $1.6 million on the pretax book income of $24.0 million) for the three months ended March 31, 2021, as compared to 23.2% for the three months ended March 31, 2020. The effective tax rate for the three months ended March 31, 2021 was lower than the rate of the prior year period primarily due to the recognition of excess tax benefits on stock-based compensation. The total gross unrecognized tax benefit as of March 31, 2021 and December 31, 2020 was $2.5 million and $2.2 million, respectively, excluding interest, penalties and related tax benefits. The Company estimates the unrecognized tax benefit as of March 31, 2021 may decrease over the upcoming 12 months by an amount up to $0.8 million related to settlements with taxing authorities and expiring statutes of limitations. For the remaining liability, due to the uncertainties related to these tax matters, the Company is unable to make a reasonable estimate as to when cash settlement with a taxing authority will occur. As of March 31, 2021, accrued interest was $0.9 million and accrued penalties were less than $0.1 million, excluding any related income tax benefits. As of December 31, 2020, accrued interest was $0.9 million and accrued penalties were less than $0.1 million, excluding any related income tax benefits. The Company recognizes interest accrued related to unrecognized tax benefits and penalties as a component of its income tax provision recognized in its Consolidated Statements of Comprehensive Income. The Company files federal income tax returns and the Company or one of its subsidiaries file income tax returns in various state and international jurisdictions. With few exceptions, the Company is no longer subject to federal tax examinations by tax authorities for years before 2017 and state or non-United States tax examinations by tax authorities for years before 2011. The Company believes that adequate reserves have been provided related to all matters contained in the tax periods open to examination. On March 11, 2021, the American Rescue Plan Act of 2021 (“ARP Act”) was enacted in response to the COVID-19 pandemic. The Company is continuing to evaluate the impact of the ARP Act, but at present does not expect the ARP Act would result in a material impact to our income tax benefit or provision.
