Mar. 31, 2021
Income Tax Disclosure [Abstract]
Income Tax [Text Block]	Income Taxes The effective tax rate was 13.8% for the three months ended March 31, 2021, compared to (10.6)% in 2020. The effective tax rate for the three months ended March 31, 2021 was impacted by the tax effect of the equity consideration included in the Aggregate Stock Consideration subject to vesting conditions, and discrete income tax items related to excess tax benefits from the vesting of our annual restricted stock award grants and stock option exercises, and the release of domestic and foreign tax valuation allowances. The effective tax rate for the three months ended March 31, 2020 was primarily impacted as a result of the tax benefit of net operating loss carrybacks at a 35% tax rate that became available as a result of the Coronavirus Aid, Relief, and Economic Security Act, enacted on March 27, 2020 (the “CARES Act”).
