Compensation Related Costs [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Restricted Stock Units (RSUs) The Company’s Stock Incentive Plan provides for the granting of stock options and restricted stock units to executive officers, other key employees and non-management directors. Restricted stock unit awards may be based on performance (performance-based) or on service over a requisite time period (time-based). Performance-based and time-based RSU equity awards represent the contingent right to receive one share of the Company’s common stock per RSU if the vesting conditions and/or performance criteria are satisfied. The RSUs have no dividend or voting rights until vested. In November 2015, a total of 330,000 performance-based RSU equity awards were granted to the Company’s Chairman, its Chief Executive Officer and its Chief Operating Officer. These awards vest at the end of a three-year performance period ending September 30, 2018. The number of units that ultimately vest depends on the Company’s relative position as compared to its peers at the end of the three-year period in achieving certain performance criteria and can range from 0% to 200% of the number of units granted. The performance criteria are total shareholder return; return on investment; selling, general and administrative expense containment; and gross profit. The grant date fair value of these equity awards was $30.81 per unit. Compensation expense related to these grants was $1.3 million and $3.6 million in the three and nine months ended June 30, 2016, respectively, based on the Company’s performance against the peer group, the elapsed portion of the performance period and the grant date fair value of the award. During the nine months ended June 30, 2016, a total of 2.1 million time-based RSUs were granted to the Company’s executive officers, other key employees and non-management directors (collectively, approximately 570 recipients). The weighted average grant date fair value of these equity awards was $23.14 per unit, and they vest annually in equal installments over periods of three to five years. Compensation expense related to these grants was $2.4 million and $6.3 million in the three and nine months ended June 30, 2016, 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.
