Debt and Financing Activities [Abstract]
Debt and Financing Activities	6. Debt and Financing Activities Accounts Receivable Sales Facility In May 2011, we renewed our existing accounts receivable sales facility (the “Facility”) for a one year period under terms substantially similar to those previously in place. The committed balance of this Facility is $1.35 billion, although from time-to-time, the available amount of the Facility may be less than $1.35 billion based on accounts receivable concentration limits and other eligibility requirements. The renewed Facility will expire in May 2012. At June 30, 2011 and March 31, 2011, there were no securitized accounts receivable balances or secured borrowings outstanding under the Facility. Additionally, there were no sales of interests to third-party purchaser groups in the quarters ended June 30, 2011 or 2010. The Facility contains requirements relating to the performance of the accounts receivable and covenants relating to the Company. If we do not comply with these covenants, our ability to use the Facility may be suspended and repayment of any outstanding balances under the Facility may be required. At June 30, 2011 and March 31, 2011, we were in compliance with all covenants. Revolving Credit Facility We have a syndicated $1.3 billion five-year senior unsecured revolving credit facility, which expires in June 2012. Borrowings under this credit facility bear interest based upon either a Prime rate or the London Interbank Offered Rate. There were no borrowings under this facility during the first quarters of 2012 and 2011. As of June 30, 2011 and March 31, 2011, there were no amounts outstanding under this facility.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
