Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax benefit was $2,607 for the three months ended March 31, 2021 resulting in an effective tax rate of 16.2%. The income tax benefit was $9,510 for the three months ended March 31, 2020 resulting in an effective tax rate of 91.7%. The decrease in the income tax benefit for the three months ended March 31, 2021, as compared to the same period in 2020, is primarily due to the discrete tax benefits recognized under the CARES Act enacted in 2020 and an agreement with the IRS in the first quarter of 2020 on audit adjustments resulting from the U.S. Federal Income Tax audit of the tax years 2015, 2016 and 2017, all of which was recorded during the three months ended March 31, 2020. Benefits from these prior year items did not recur during the three months ended March 31, 2021.
