Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate for the three months ended March 31, 2021 (Successor) and March 31, 2020 (Predecessor) was 9.4% and 5.6%, respectively. The effective tax rates for the three months ended March 31, 2021 and 2020 were lower than the statutory federal rate of 21% as a result of the Company’s valuation allowance, which was initially recorded against substantially all of the Company’s net deferred tax assets as of March 31, 2020 and was maintained as of March 31, 2021. Valuation allowance. The Company’s valuation allowance as of March 31, 2021 was $570.3 million, which increased $4.9 million from $565.4 million as of December 31, 2020. The Company concluded it is more likely than not that some or all of the benefits from its deferred tax assets will not be realized, and as such, recorded a valuation allowance on these assets. Management assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax assets. A significant piece of objective negative evidence evaluated is the cumulative loss incurred over recent years, excluding the impact of the voluntary restructuring under Chapter 11 of the Bankruptcy Code in 2020. Such objective negative evidence limits the ability to consider other subjective positive evidence. The amount of the deferred tax asset considered realizable could be adjusted if estimates of future taxable income are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as future growth. As such, the Company will continue to assess the valuation allowance on an ongoing basis.
