CY2021	us-gaap	Prior Period Reclassification Adjustment Description PriorPeriodReclassificationAdjustmentDescription	Elimination of International Lag ReportingHistorically our consolidated financial statements which have a year-end of December 31, reflected results of subsidiaries outside of North America on a one-month lag with a year-end of November 30. Effective January 1, 2021, we eliminated the one-month reporting lag for our subsidiaries outside of North America and aligned the year-end for all subsidiaries to December 31. The elimination of this reporting lag represented a change in accounting principle, which the Company believes to be preferable as it provides investors with the most current information. This change in accounting policy was applied retrospectively to all periods since February 8, 2019 ("Successor periods") after the Take-Private Transaction. The Consolidated Balance Sheet as of December 31, 2020, the Consolidated Statement of Operations and Comprehensive Income (Loss), the Consolidated Statements of Cash Flows and the Consolidated Statements of Stockholder Equity (Deficit) for the year ended December 31, 2020 and the period from January 1, 2019 to December 31, 2019 (Successor) have been recast to reflect this change in accounting policy.Where appropriate, we have reclassified certain prior year amounts to conform to the current year presentation
