Incentive and Deferred Compensation Plans	Incentive and Deferred Compensation Plans Annual Incentive Plan. In June 2013, the Compensation Committee of the Company’s Board approved an annual incentive plan effective June 2013 for all employees and discontinued the Company’s then existing cash bonus program with final payments under the program of approximately $10.9 million made in July 2013. For certain members of management, the annual incentive plan incorporates objective performance criteria, individual performance goals and competitive target award levels for the 2015 performance year with payout percentages ranging from 0% to 200% of specified target levels based on actual performance. As of December 31, 2015 and 2014, the Company had accrued approximately $21.6 million and $21.1 million, respectively, for the annual incentive for all employees, including an accrual for an annual incentive for specified members of management based on actual performance compared to target levels specified in the annual incentive plan. The annual incentive plan was replaced in January 2016 by the Company’s newly-implemented performance incentive plan. See Note 22. Deferred Compensation Plans. The Company maintains a 401(k) retirement plan for its employees. Under the Plan, eligible employees may elect to defer a portion of their earnings up to the maximum allowed by regulations promulgated by the Internal Revenue Service (“IRS”). The Company made matching contributions to the plan through cash purchases of Company stock equal to 100% on the first 10% employee deferred wages for the years ended December 31, 2015 and 2014 and 100% on the first 15% of employee deferred wages for the year ended December 31, 2013. Retirement plan expense for the years ended December 31, 2015, 2014 and 2013 was approximately $7.9 million, $8.7 million and $11.0 million, respectively. The Company maintains a non-qualified deferred compensation plan that allows eligible highly compensated employees to elect to defer income exceeding the IRS annual limitations on qualified 401(k) retirement plans. The Company made matching contributions on non-qualified contributions up to a maximum of 10% of employee compensation for the years ended December 31, 2015 and 2014 and 15% of employee compensation for the year ended December 31, 2013. For the years ended December 31, 2015, 2014 and 2013, employer contributions of cash purchases of Company stock were approximately $2.9 million, $2.0 million and $2.7 million, respectively. Any assets placed in trust by the Company to fund future obligations of the Company’s non-qualified deferred compensation plan are subject to the claims of creditors in the event of insolvency or bankruptcy, and participants are general creditors of the Company as to their own deferred compensation in, and the Company’s contributions to, the plan.

The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.
