General Discussion of Pension and Other Postretirement Benefits [Abstract]
Benefit Plans	BENEFIT PLANS Historically, the Company participated in several multi-employer defined benefit pension plans (“MEPPs”) providing defined benefits to union employees under the terms of collective bargaining agreements. The Company recognized charges related to its withdrawal from the last of these plans of $4.3 million for the year ended March 31, 2012. The Company successfully negotiated its withdrawal from all MEPPs in which it previously participated. The Company has a defined contribution 401(k) plan (the “401(k) plan”) covering substantially all full-time employees. Under the terms of the 401(k) plan, the Company makes matching contributions of up to two percent of participant wages. Amounts expensed under the 401(k) plan for fiscal 2014, 2013 and 2012 were $12.3 million, $11.7 million and $11.1 million, respectively. The Company has a deferred compensation plan that is a non-qualified plan. The deferred compensation plan allows eligible employees and non-employee directors, who elect to participate in the plan, to defer the receipt of taxable compensation. Participants may set aside up to a maximum of 75% of their base salary and up to a maximum of 100% of their bonus compensation or directors’ fees in tax-deferred investments. The Company’s deferred compensation plan liabilities are funded through an irrevocable rabbi trust. The assets of the trust, which consist of open-ended mutual funds, cannot be reached by the Company or its creditors except in the event of the Company’s insolvency or bankruptcy. Assets held in the rabbi trust were $16.4 million and $13.6 million at March 31, 2014 and 2013, respectively, and are included within other non-current assets on the consolidated balance sheets. The Company’s deferred compensation plan liabilities were $16.4 million and $13.6 million at March 31, 2014 and 2013, respectively, and are included within other non-current liabilities on the consolidated balance sheets. Gains or losses on the deferred compensation plan assets are recognized as other income, net, while gains or losses on the deferred compensation plan liabilities are recognized as compensation expense in the consolidated statements of earnings.
