Debt Disclosure [Abstract]
Line of Credit	LINE OF CREDIT On November 30, 2010, we entered into a five-year syndicated credit agreement pursuant to which we obtained an unsecured revolving credit facility (the “Facility”). This credit agreement, as amended from time to time, is referred to as the “Credit Agreement.” The aggregate amount of the Credit Agreement is $800.0 million, and the current maturity date of the Facility is December 11, 2018. At our option, we may increase the size of the Facility to $1.0 billion at any time prior to the expiration date (subject to receipt of commitments for the increased amount from existing and new lenders). Borrowings under the Facility bear interest at a rate equal to an applicable margin plus, at our option, either a (i) eurodollar rate (generally LIBOR) or (ii) base rate determined by reference to the highest of (1) the federal funds rate plus 0.50%, (2) the prime rate published by Bank of America, N.A. from time to time, and (3) the eurodollar rate plus 1.00%. The applicable margin is a percentage per annum varying from zero to 0.75% for base rate loans and 1.00% to 1.75% for eurodollar loans, based upon our leverage ratio. We also pay a commitment fee, based on the leverage ratio, payable quarterly in arrears, ranging from 0.200% to 0.275% on the average daily unused portion of the Facility. For purposes of this calculation, irrevocable standby letters of credit, which are issued primarily in conjunction with our insurance programs, and cash borrowings are included as outstanding under the Facility. The Credit Agreement contains certain leverage and financial covenants that require us to maintain a maximum leverage ratio of 3.25 to 1.0 at the end of each fiscal quarter (except as described below), a minimum fixed charge coverage ratio of 1.50 to 1.0 at any time, and a consolidated net worth in an amount not less than the sum of (i) $570.0 million, (ii) 50% of our consolidated net income (with no deduction for net loss), and (iii) 100% of our aggregate increases in stockholders’ equity, beginning on November 30, 2010. In the event of a material acquisition, as defined in the Credit Agreement, we may elect to increase the leverage ratio to 3.50 to 1.0 for a total of four fiscal quarters. On September 2, 2015, we entered into an amendment to our Credit Agreement to update the definition of Consolidated EBITDA that is used in the calculation of certain leverage and financial covenants. The revised definition of Consolidated EBITDA provides addbacks for: (i) restructuring and related charges arising out of our 2020 Vision, (ii) adjustments with respect to insurance liabilities for periods prior to 2015, and (iii) costs arising from the consolidation of locations, subject to the limitation that the aggregate amount of all addbacks does not exceed $75.0 million. In addition, the amendment permits us to dispose of certain assets and to repurchase our common stock without regard to a cap so long as certain leverage tests are met. As of October 31, 2015, we were in compliance with these covenants. If an event of default occurs under the Credit Agreement, including certain cross-defaults, insolvency, change in control, or violation of specific covenants, the lenders can terminate or suspend our access to the Facility, declare all amounts outstanding under the Facility (including all accrued interest and unpaid fees) to be immediately due and payable, and require that we cash collateralize the outstanding standby letters of credit obligations. The Facility is available for working capital, the issuance of up to $300.0 million for standby letters of credit, the issuance of up to $50.0 million in swing line advances, the financing of capital expenditures, and other general corporate purposes, including acquisitions and investments in subsidiaries, subject to certain limitations, where applicable, as set forth in the Credit Agreement. At October 31, 2015, the total outstanding amounts under the Facility in the form of cash borrowings and standby letters of credit were $158.0 million and $112.9 million, respectively. At October 31, 2014, the total outstanding amounts under the Facility in the form of cash borrowings and standby letters of credit were $319.8 million and $114.9 million, respectively. At October 31, 2015 and 2014, we had up to $529.1 million and $365.3 million borrowing capacity, respectively, under the Facility, the availability of which was subject to, and limited by, compliance with the covenants described above. Interest Rate Swaps During 2013, we entered into a series of interest rate swap agreements with effective start dates of March 18, 2013 and April 11, 2013, totaling an underlying aggregate notional amount of $155.0 million, pursuant to which we receive variable interest payments based on LIBOR and pay fixed interest on such amounts, at rates ranging from 0.44% to 0.47%. These interest rate swap agreements will mature between March 18, 2016 and April 11, 2016 and are intended to hedge the interest rate risk associated with our floating-rate, LIBOR-based borrowings under our Facility. The swaps were designated and accounted for as cash flow hedges from inception. We recognize all interest rate swaps on the accompanying consolidated balance sheets at fair value. The fair values of the interest rate swaps are estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates using observable benchmarks for LIBOR forward rates at the end of the period. See Note 7, “Fair Value of Financial Instruments,” for more information. Each of the swap derivatives is designated as a cash flow hedge, and the effective portion of the derivative’s mark-to-market gain or loss is initially reported as a component of AOCL and subsequently reclassified into earnings when the hedged transactions occur and affect earnings. The ineffective portion of the gain or loss is reported in earnings immediately. Interest payables and receivables under the swap agreements are accrued and recorded as adjustments to interest expense. At October 31, 2015 and 2014, the amounts recorded in AOCL were $0.1 million ($0.1 million, net of taxes) and $0.2 million ($0.1 million, net of taxes), respectively. At October 31, 2015, the amount expected to be reclassified from AOCL to earnings during the next twelve months was $0.1 million

Interest Rate Swaps

During 2013, we entered into a series of interest rate swap agreements with effective start dates of March 18, 2013 and April 11, 2013, totaling an underlying aggregate notional amount of $155.0 million, pursuant to which we receive variable interest payments based on LIBOR and pay fixed interest on such amounts, at rates ranging from 0.44% to 0.47%.
