Redeemable long-term obligations consist primarily of tax-exempt variable-rate put bonds that are included as current liabilities because they become redeemable at the option of the bondholders during the year following the balance sheet date.

The company periodically enters into interest rate swaps on a portion of its short-term debt. See Note 7 for information concerning the company's debt-related derivative activities.

At December 31, 2007, the company had $4,950 of committed credit facilities with banks worldwide, which permit the company to refinance short-term obligations on a long-term basis. The facilities support the company's commercial paper borrowings. Interest on borrowings under the terms of specific agreements may be based on the London Interbank Offered Rate or bank prime rate. No amounts were outstanding under these credit agreements during 2007 or at year-end.

At December 31, 2007 and 2006, the company classified $4,382 and $4,450, respectively, of short-term debt as long-term. Settlement of these obligations is not expected to require the use of working capital in 2008, as the company has both the intent and the ability to refinance this debt on a long-term basis.
