Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items. The Company’s effective tax rate is expressed as income tax benefit as a percentage of loss before income taxes. In the period September 1 through September 30, 2017 (Successor), the Company recorded income tax expense of $286 on pre-tax loss from continuing operations of $535, for an effective tax rate of (53.5)%. In the three months ended September 30, 2018 (Successor), the Company recorded income tax benefit of $2,068 on pre-tax loss of $8,723, for an effective tax rate of 23.7%. In the period July 1, 2017 through August 31, 2017 (Predecessor), the Company recorded income tax benefit of $1,395 on pre-tax income of $70,828, for an effective tax rate of (2.0)%. In the nine months ended September 30, 2018 (Successor), the Company recorded income tax benefit of $4,026 on pre-tax loss of $24,335, for an effective tax rate of 16.5%. In the period January 1, 2017 through August 31, 2017 (Predecessor), the Company recorded income tax benefit of $1,387 on pre-tax income of $34,803, for an effective tax rate of (4.0)%. On December 22, 2017, the U.S. enacted significant changes to the U.S. tax law following the passage and signing of H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (the “Tax Act”) (previously known as “The Tax Cuts and Jobs Act”). The Tax Act included significant changes to existing tax law, including, but not limited to, a permanent reduction to the U.S. federal corporate income tax rate from 35% to 21%, effective January 1, 2018. On December 22, 2017, the Securities Exchange Commission ("SEC") issued Staff Accounting Bulletin 118, "SAB 118", which expresses views of the SEC regarding ASC Topic 740, "Income Taxes" ("ASC 740"), in the reporting period that includes the enactment date of the Tax Act. Subsequent to the issuance of SAB 118, in March 2018, the FASB issued ASU 2018-05 "Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin 118," which formally amended ASC 740 for the guidance previously provided by SAB 118. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record and provisional estimate in the financial statements. Given the complexity of the Tax Act and anticipated guidance from the U.S. treasury about implementing the Tax Act, the Company’s analysis and accounting for the tax effects of the enactment of the Tax Act is preliminary. The Company has made provisional estimates in accordance with SAB 118 but has not fully completed its analysis and calculation of foreign earnings subject to the transition tax or its analysis of certain other aspects of the Tax Act that could result in adjustments to the remeasurement of deferred tax balances. Upon completion of the analysis in 2018, these estimates may be adjusted through income tax benefit or expense in the Consolidated Statements of Operations and Comprehensive (Loss) Income. No adjustments to these provisional estimates were made in either the three or nine months ended September 30, 2018 (Successor). The Company expects to finalize its accounting for the tax effects of the Tax Act in the fourth quarter of 2018. The Tax Act subjects a U.S. shareholder to tax on Global Intangible Low-Taxed Income (“GILTI”) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, "Accounting for Global Intangible Low-Taxed Income", states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. Given the complexity of the GILTI provisions, the Company is still evaluating the effects of the GILTI provisions and have not yet determined our accounting policy. At September 30, 2018 (Successor), because the Company is still evaluating the GILTI provisions and its analysis of future taxable income that is subject to GILTI, the Company has included GILTI related to current year operations only in its estimated annual effective tax rate and has not provided additional GILTI on deferred items. Accordingly, in both the three months ended September 30, 2018 (Successor) and the nine months ended September 30, 2018 (Successor), the Company's income tax provision reflects i) the current year impacts of the Tax Act on the estimated annual effective tax rate and ii) discrete items, if any, resulting directly from the enactment of the Tax Act based on information available, prepared, or analyzed (including computations) in reasonable detail. There were no material discrete impacts from the enactment of the Tax Act in either the three months ended September 30, 2018 (Successor) or nine months ended September 30, 2018 (Successor). The most significant factors impacting the effective tax rate in the three and nine months ended September 30, 2018 (Successor) were the impact of the U.S. federal corporate tax rate reduction in connection with the enactment of the Tax Act on the estimated annual effective tax rate, the foreign rate differential, and the release of valuation allowances in jurisdictions that have become profitable.
