Income Tax Disclosure [Text Block] | Note 11 – Income Taxes The Company is subject to income tax in multiple jurisdictions and the use of estimates is required to determine the provision for income taxes. For the three months ended March 31, 2021 and 2020, the Company recorded an income tax provision of $0.2 million and $3.9 million, respectively. The income tax provision is based on the estimated annual effective tax rate for the year applied to pre-tax income. The results for the three months ended March 31, 2021 reflect losses in jurisdictions that are not eligible for tax benefits on account of valuation allowances. The effective income tax rate for the three months ended March 31, 2021 was 6.0 percent compared to 21.8 percent in the same period of the prior year. The effective tax rate decreased by 15.8 percent for the three months ended March 31, 2021 when compared to the same period in 2020, primarily due to an increase in tax benefits from the vesting of restricted stock and the exercise of stock options. The effective income tax rate for the three months ended March 31, 2021 differs from the U.S. federal statutory rate of 21.0 percent due to various factors, including operating in multiple state and foreign jurisdictions and tax credits for which the Company qualifies. The Company had unrecognized tax benefits totaling $4.9 million as of March 31, 2021 and $4.8 million as of December 31, 2020, respectively, all of which, if recognized, would affect the Company’s effective tax rate. The Company recognizes interest and penalties related to income tax matters in income tax expense, and reports the liability in current or long-term income taxes payable as appropriate. On March 11, 2021, the President signed into law the ARP Act, a legislative package which is generally not significant to the Company's current tax footprint; however, the Company will continue to assess the ARP Act on an ongoing basis. Similar tax provisions and other stimulus measures have been granted either before or after March 31, 2021 by certain foreign and U.S. state jurisdictions, which the Company continues to evaluate and apply, if applicable.
