Income Tax Disclosure [Abstract]
Income Tax	Income TaxThe effective income tax rate was 16.6% and (0.5)% for the three months ended September 30, 2021 and 2020 and 3.8% and (0.8)% for the nine months ended September 30, 2021 and 2020. During the current quarter, the tax rate was impacted by a partial release of valuation allowance totaling $3.1 million as a result of acquisitions. The effective tax rate differs from the U.S. federal rate primarily due to the impacts of the valuation allowance placed on the Company’s deferred tax assets and state minimum taxes.
