CY2020	us-gaap	Prior Period Reclassification Adjustment Description PriorPeriodReclassificationAdjustmentDescription	ReclassificationsCertain prior period amounts have been reclassified to conform to the 2020 presentation. In the first quarter of 2020, in connection with a reorganization of the Company’s management structure after the Separation and emergence from the Chapter 11 cases, the Company reevaluated the classification of certain expenses to determine whether such expenses should be included within Direct operating expenses, Selling, general & administrative (“SG&A”) expenses or Corporate expenses. As a result, certain expenses were reclassified from Corporate expenses to Direct operating or SG&A expenses. In addition, certain expenses were reclassified from SG&A expenses to Direct operating expenses. The reclassifications had no impact on the Company's Operating Income (Loss) or Net Income (Loss). Accordingly, the Company recast the corresponding amounts in the prior period to conform to the current expense classifications. The corresponding current and prior period segment disclosures were recast to reflect the current expense classifications.
