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 March 31, 2014, 28,500 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. Participants have no rights to the underlying debt. The total amount of compensation available to be paid under the RDU Plan was initially to be based on two components, a principal component and an interest component. The principal component credits the RDU Plan with a notional amount equal to the $28.5 million face value of the Senior Subordinated Notes (the "Debt Pool"), together with certain redemption premium equivalents as noted below. 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, except 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. 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 connection with the IPO and the partial redemption of the Senior Subordinated Notes, the Company amended the RDU Plan to increase the retentive value of the plan. In accordance with the original terms of the RDU Plan, the principal component of the RDUs converted to a cash-denominated pool upon the redemption of the Senior Subordinated Notes. In addition, the Company added $1.4 million to the principal component in the year ended December 31, 2013 as redemption premium equivalents in accordance with the terms of the RDU plan. Under the terms of the amended RDU Plan, upon the partial redemption of outstanding Senior Subordinated Notes, the RDUs ceased to accrue the proportionate related interest component credits. The amended RDU Plan provides participants the opportunity to share on a pro rata basis in cash retention pools payable to participants who satisfy certain retention requirements. The aggregate amount of the retention pools was determined to be $15.0 million based upon the amount of interest component credits that would have been allocated to the RDU Plan if the Senior Subordinated Notes had remained outstanding from August 1, 2013 through maturity. The Company recorded a pre-tax charge of $7.5 million in the year ended December 31, 2013 for payment of the first cash retention pool. The second cash retention pool payment is expected to be made to participants who remain employed through December 31, 2015 in the first quarter of 2016. Participants continue to accrue an interest component credit for the proportionate amount of Senior Subordinated Notes still outstanding, payable on the aforementioned semi-annual due dates; such payments, however, will be deducted from the second retention pool payment amount of $7.5 million. Unrecognized compensation expense as of March 31, 2014 of approximately $7 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 March 31, 2014 and 2013, respectively. At March 31, 2014 and December 31, 2013, the Company had $24.1 million and $21.8 million of liabilities related to the RDU Plan recorded on the consolidated balance sheets, respectively. 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.

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.
