Incentive and Deferred Compensation Plans	Incentive and Deferred Compensation Plans Annual Incentive Plan. The Annual Incentive Plan ("AIP") incorporates quantitative performance measures, strategic qualitative goals and competitive target award levels for management and employees for the 2018 and 2017 performance years. Potential payout percentages ranged from 0% to 200% of specified target levels based on actual performance. Payment for the 2018 performance year will be made in the first quarter of 2019 based on actual performance as determined by the Board of Directors relative to the targets specified in the plan. As of December 31, 2018, the Company had accrued approximately $6.6 million for the 2018 AIP. Payment of $8.7 million was made in the first quarter of 2018 for the 2017 performance year. Performance Incentive Plan. In January 2016, the Company implemented a performance incentive plan which included long-term incentive awards, and provided for quarterly cash payments at a target percentage to participants based upon corporate performance goals with aggregate annual payout opportunity ranging from 0% to 200%. The first three quarterly cash payments were limited to no greater than target amounts with a cash make up payment in the first quarter of 2017 for actual performance based on the Company’s annual results. Under this plan, the Predecessor Company paid out approximately $17.8 million during the first two quarters of 2016 and the Successor Company paid out approximately $7.1 million during the fourth quarter of 2016 and approximately $15.8 million during the first quarter of 2017. 401(k) Plan. The Company maintains a 401(k) retirement plan for its employees. Under this plan, eligible employees may elect to defer a portion of their earnings up to the maximum allowed by IRS. For the years ended December 31, 2018, and 2017, the Successor 2016 Period and the Predecessor 2016 Period, the Company made matching contributions to the plan equal to 100% on the first 10% of employee deferred wages, excluding incentive compensation, totaling $2.8 million, $3.6 million, $0.9 million and $4.9 million, respectively. The decrease in contributions is due primarily to reductions in force that occurred in 2017 and 2018. Participants in the plan are immediately 100% vested in the discretionary employee contributions and related earnings on those contributions. The Company's matching contributions and related earnings vest based on years of service, with full vesting occurring on the fourth anniversary of employment. Deferred Compensation Plans. The Company maintained a non-qualified deferred compensation plan that allowed eligible highly compensated employees to elect to defer income exceeding the IRS annual limitations on qualified 401(k) retirement plans through December 31, 2016. The Company made insignificant matching contributions on non-qualified contributions for the Successor 2016 Period and the Predecessor 2016 Period. On December 31, 2016, the Successor Company began the process of terminating the non-qualified deferred compensation plan and no employee or employer contributions were made to the plan after that date. In accordance with the plan termination procedures, the $5.1 million of remaining assets in the plan as of December 31, 2017, were fully distributed to participating employees during the first quarter of 2018. These assets were included in other current assets in the consolidated balance sheet at December 31, 2017.
