Deferred Compensation Plan [Abstract]
Deferred Compensation Plan	Deferred Compensation Plan On March 10, 2010, in connection with the Company's purchase of $28.5 million principal amount of its outstanding senior subordinated debt, the Company established the Restricted Debt Unit Plan (the “RDU Plan”), an unfunded nonqualified deferred compensation plan. The total number of RDUs that can be granted under the RDU Plan is 28,500. As of June 30, 2013, 26,549 RDUs were outstanding. RDUs that are outstanding vest daily on a pro rata basis over the three-year period from January 1, 2012 (or, if later, the date of hire or the date of a subsequent RDU grant) through December 31, 2014. The total amount of compensation available to be paid under the RDU Plan is based on two components, a principal component and an interest component. Participants have no rights to the underlying debt. The principal component credits the RDU Plan with an amount equal to the $28.5 million face value of the Company's Senior Subordinated Notes (the “Debt Pool”). Payment of the principal component of the RDU Plan is expected to be made on October 12, 2017, unless accelerated due to a sale of the Company. By December 31, 2014, amounts accrued under the RDU Plan are expected to equal the present value of the principal component, plus any accrued unpaid interest thereon. The interest component credits the RDU Plan with amounts equal to the interest that would have been earned on the Debt Pool from March 10, 2010 through maturity on October 12, 2017 as discussed below. Interest amounts for 2010 and 2011 were deferred until 2012, and thereafter, interest amounts were paid to participants semi-annually on the interest payment due dates. Payments totaling $1.7 million were made to participants under the RDU Plan in April 2013 in connection with the semi-annual interest payment due. As described in Note 13, the Company used a portion of the IPO proceeds together with incremental borrowings to redeem $324.0 million of the total Senior Subordinated Notes outstanding on August 1, 2013. In accordance with the terms of the RDU Plan, upon redemption of Senior Subordinated Notes, the RDUs cease to accrue the related interest component credits. The Company expects to give participants the opportunity to share on a pro rata basis in cash retention pools that will be payable to participants who satisfy certain retention requirements. The aggregate amount of the retention pools will be determined based on the amount of interest component credits that would have been allocated to the RDU Plan if the Senior Subordinated Notes remained outstanding through maturity. The Company expects to record a pre-tax charge of $7.5 million in the third quarter of 2013 for payment of the first cash retention pool. Including this charge, unrecognized compensation expense as of June 30, 2013 of approximately $21 million is expected to be recognized through 2014 and approximately $7 million in 2015 through 2017. Payments under the RDU Plan may be impacted if certain significant events occur or circumstances change that would impact the financial condition or structure of the Company. Compensation expense of $2.2 million and $2.1 million related to the RDU Plan was recognized for the three months ended June 30, 2013 and 2012, respectively, and $4.3 million and $4.2 million for the six months ended June 30, 2013 and 2012, respectively. At June 30, 2013 and December 31, 2012, the Company had $18.1 million and $15.5 million of liabilities related to the RDU Plan recorded on the consolidated balance sheets, respectively.

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.
