Line of Credit Facility [Abstract]
Line of Credit Facility	7. Line of Credit Facility On November 30, 2010, the Company terminated its then-existing $450.0 million syndicated line of credit and replaced it with a $650.0 million five-year syndicated line of credit that is scheduled to expire on November 30, 2015 (the “Facility”), with the option to increase the size of the Facility to $850.0 million at any time prior to the expiration (subject to receipt of commitments for the increased amount from existing and new lenders). The Facility is available for working capital, the issuance of standby letters of credit, the financing of capital expenditures, and other general corporate purposes, including acquisitions. The Facility includes covenants limiting liens, dispositions, fundamental changes, investments, indebtedness, and certain transactions and payments. In addition, the Facility also requires that the Company maintain the following three financial covenants, which are described in Note 16, “Subsequent Events,” to the Consolidated Financial Statements set forth in the Company’s Annual Report on Form 10-K for 2010: (1) a fixed charge coverage ratio; (2) a leverage ratio; and (3) a consolidated net worth test. The Company was in compliance with all covenants as of April 30, 2011. As of April 30, 2011, the total outstanding amount under the Facility in the form of cash borrowings was $396.0 million. Available credit under the line of credit was up to $146.9 million at April 30, 2011. The Company’s ability to draw down available amounts under its line of credit is subject to compliance with the covenants described above. Interest Rate Swaps On February 19, 2009, the Company entered into a two-year interest rate swap agreement with an underlying notional amount of $100.0 million, pursuant to which the Company received variable interest payments based on LIBOR and paid fixed interest at a rate of 1.47%. This interest rate swap expired on February 19, 2011. During the life of this interest rate swap, the critical terms of the swap matched the terms of the debt, which resulted in no hedge ineffectiveness. On October 19, 2010, the Company entered into a three-year forward starting interest rate swap agreement with an underlying notional amount of $25.0 million, pursuant to which the Company receives variable interest payments based on LIBOR and pays fixed interest at a rate of 0.89%. The effective date of this hedge was February 24, 2011. This swap is intended to hedge the interest risk associated with the Company’s forecasted floating-rate, LIBOR-based debt. As of April 30, 2011, the critical terms of the swap matched the terms of the debt, resulting in no hedge ineffectiveness. On an ongoing basis (no less than once each quarter), the Company assesses whether its LIBOR-based interest payments are probable of being paid during the life of the hedging relationship. The Company also assesses the counterparty credit risk, including credit ratings and potential non-performance of the counterparty, when determining the fair value of the swap. As of April 30, 2011, the fair value of the remaining interest rate swap was $0.2 million, which was included in other investments and long-term receivables on the accompanying condensed consolidated balance sheet. The effective portion of this cash flow hedge is recorded within accumulated other comprehensive loss and reclassified into interest expense in the same period during which the hedged transactions affect earnings. Any ineffective portion of the hedge is recorded immediately to interest expense. No ineffectiveness existed at April 30, 2011. The amount included in accumulated other comprehensive loss is $0.2 million ($0.1 million, net of taxes) at April 30, 2011.
