we currently have no amounts outstanding under the facility. The facility matures in December 2011, and can be extended for one additional year on both the first and second anniversary date. Based on our current long-term senior unsecured debt ratings of A+ and A2 from Standard and Poor’s Corporation and Moody’s Investor Services, respectively, the interest rate charged on any outstanding borrowings would be the prevailing LIBOR plus 0.15%. The facility fee is 0.05% of the total commitment.

If our long-term debt rating were to decline, the facility fee and interest rate under our committed credit facility would increase. Conversely, if our long-term debt rating were to improve, the facility fee and interest rate would decrease. Changes in our long-term debt rating would not trigger acceleration of maturity of any then outstanding borrowings or any future borrowings under the committed credit facility. Under this committed credit facility, we have agreed to various covenants. These covenants include limits on our disposal of fixed assets and the amount of debt secured by liens we may incur, and set a minimum capitalization ratio. In the event we were to have any borrowings outstanding under this facility, failed to meet any covenant, and were unable to obtain a waiver from a majority of the banks, any borrowings would become immediately due and payable. As of May 31, 2007, we were in full compliance with each of these covenants and believe it is unlikely we will fail to meet any of these covenants in the foreseeable future.

Liquidity is also provided by our commercial paper program, under which there was no amount outstanding at May 31, 2007 or May 31, 2006. We currently have short-term debt ratings of A1 and P1 from Standard and Poor’s Corporation and Moody’s Investor Services, respectively.

We currently believe that cash generated by operations, together with access to external sources of funds as described above, will be sufficient to meet our operating and capital needs in the foreseeable future.

Recently Issued Accounting Standards

In June 2006, the FASB ratified the consensus reached on Emerging Issues Task Force (“EITF”) Issue No. 06-3, “How Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement (That Is, Gross versus Net Presentation)” (“EITF 06-3”). EITF 06-3 requires disclosure of the method of accounting for the applicable assessed taxes and the amount of assessed taxes that are included in revenues if they are accounted for under the gross method. EITF 06-3 was adopted in the fourth quarter ended May 31, 2007; however, since we present revenues net of any taxes collected from customers, no additional disclosures were required.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (“FAS 158”). FAS 158 requires employers to fully recognize the obligations associated with single-employer defined benefit pension, retiree healthcare and other postretirement plans in their financial statements. We adopted the provisions of FAS 158 in the fourth quarter ended May 31, 2007. See Note 12— Benefit
