Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The Company recorded a $53.3 million tax benefit (36.4 percent effective tax rate) compared to a $21.2 million tax provision (23.1 percent effective tax rate) for the three months ended June 30, 2020 and 2019, respectively. The effective tax rate for the three months ended June 30, 2020 differed from the statutory federal income tax rate of 21.0 percent primarily due to the tax accounting impact of the CARES Act which allows the Company to carryback the 2020 net operating loss at the 35.0 percent rate applicable in earlier years. The Company recorded a $151.0 million tax benefit (54.5 percent effective tax rate) compared to a $38.0 million tax provision (23.0 percent effective tax rate) for the six months ended June 30, 2020 and 2019, respectively. The 54.5 percent effective tax rate for the six months ended June 30, 2020 differed from the statutory federal income tax rate of 21.0 percent primarily due to the tax accounting impact of the CARES Act which includes a $39.6 million discrete federal income tax benefit related to the full utilization of 2018 and 2019 net operating losses as well as the ability to carryback the 2020 net operating loss at a 35.0 percent rate applicable in earlier years. The effective tax rate was also impacted by the remeasurement of deferred taxes and state taxes.
