Income Tax Disclosure [Abstract]
Income Taxes	Note 7. Income Taxes On March 27, 2020, Congress enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) to provide certain taxpayer relief as a result of the COVID-19 pandemic. The CARES Act included several favorable provisions that impacted income taxes, primarily the modified rules on the deductibility of business interest expense for 2019 and 2020, a five-year carryback period for net operating losses generated after 2017 and before 2021, and the acceleration of refundable alternative minimum tax credits. We evaluate our estimated annual effective income tax rate based on current and forecasted business results and enacted tax laws on a quarterly basis and apply this tax rate to our ordinary income or loss to calculate our estimated tax liability or benefit. Our income taxes are based on an estimated statutory rate of approximately 25% in 2020 and 2019. Our effective tax rate for the Predecessor period ended September 18, 2020 differed from our estimated statutory rate, primarily due to the numerous tax impacts related to the emergence from the Chapter 11 Restructuring, including the reduction of tax attributes from the exclusion of cancellation of debt income according to Section 108 of the U.S. Internal Revenue Code, and the establishment of a valuation allowance of our federal and state deferred tax assets existing after fresh start accounting. For the Successor period ended September 30, 2020, our effective tax rate differed from our estimated statutory rate as a result of a valuation allowance applied to our federal and state deferred tax assets.
