7. Current Liabilities

Current Portion of Long-Term Debt

The current portion of long-term debt consists of $500 million of 5.40% senior unsecured notes due on March 15, 2012, less the unamortized discount. Because their contractual maturities are now within one year, we transferred these notes from long-term liabilities to current liabilities during the third quarter of fiscal 2011. See Note 8, “Long-Term Obligations — Long-Term Debt,” for more information.

Unsecured Revolving Credit Facility

On March 22, 2007 we entered into an agreement with certain institutional lenders for a $500 million unsecured revolving credit facility that will expire on March 22, 2012. Advances under the credit facility will accrue interest at rates that are equal to, at our election, either Citibank’s base rate or the London InterBank Offered Rate (LIBOR) plus a margin that ranges from 0.18% to 0.575% based on our senior debt credit ratings. The applicable interest rate will be increased by 0.05% for any period in which the total principal amount of advances and letters of credit under the credit facility exceeds $250 million. The agreement includes covenants that require us to maintain a ratio of total debt to annual earnings before interest, taxes, depreciation and amortization (EBITDA) of not greater than 3.25 to 1.00 and a ratio of annual EBITDA to interest payable of not less than 3.00 to 1.00. We were in compliance with these covenants at April 30, 2011. We may use amounts borrowed under this credit facility for general corporate purposes or for future acquisitions or expansion of our business. To date we have not borrowed under this credit facility.
