Short-term Debt, Terms		The Company has a commercial paper program whereby it may from time to time issue short-term promissory notes in an aggregate amount of up to $700 million at any one time. Amounts available under the program may be borrowed, repaid, and re-borrowed from time to time. The maturities on the notes will vary, but may not exceed 365 days from the date of issuance. The notes will bear interest rates, if interest bearing, or will be sold at a discount from their face amounts.
