Income Tax Disclosure [Text Block]	12. INCOME TAXES On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits net operating loss (“NOL”) carrybacks to offset up to 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019 and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The Company’s effective tax rate was 8.5% and 24.6% for the three months ended March 31, 2020 and 2019, respectively. The decrease in the effective tax rate was primarily related to a $7.0 million income tax benefit attributable to the NOL carryback provision of the CARES Act, a $4.2 million increase in income tax benefits attributable to equity-based compensation awards and a $1.1 million decrease in income tax expenses attributable to state effective tax rate changes.
