Debt Disclosure [Abstract]
Debt and Financing Activities	Debt and Financing Activities Accounts Receivable Sales Facility In May 2013, we extended our existing accounts receivable sales facility for a six month period under terms substantially similar to those previously in place. In November 2013, we amended the facility to extend the term for an additional year, increased the maximum debt to capital ratio from 56.5% to 65% and added an extended cure period with respect to defaults under the facility relating to Celesio. The committed balance of the 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. On January 13, 2014, the amendment to the extended cure period terminated upon the failure of the 2013 Tender Offers. The increase to the debt to capital ratio remains in effect. In the fourth quarter of fiscal 2014, we amended this facility to revive the extended cure period with respect to defaults relating to Celesio. The amended facility will expire in November 2014. We anticipate renewing the facility before expiration. During the first nine months of 2014, we borrowed and repaid $150 million of short-term borrowings under the facility; and for the first nine months of 2013, we borrowed and repaid $1,125 million and $1,525 million. At December 31, 2013 and March 31, 2013, there were no short-term borrowings and related securitized accounts receivable outstanding under this facility. 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 repayments of any outstanding balances under the facility may be required. At December 31, 2013 and March 31, 2013, 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 September 2016. In November 2013, we amended this facility to increase the maximum debt to capital ratio from 56.5% to 65%, effective upon the Celesio acquisition date, and added an extended cure period with respect to defaults under the credit facility relating to Celesio. On January 13, 2014, the amendment to the Revolving Credit Facility terminated upon the failure of the 2013 Tender Offers. The maximum debt to capital ratio on this facility remained at 56.5% as of December 31, 2013. Borrowings under this facility bear interest based upon either the London Interbank Offered Rate or a prime rate. There were no borrowings under this facility during the first nine months of 2014 and 2013 and as of December 31, 2013 and March 31, 2013, there were no amounts outstanding under this facility. In the fourth quarter of fiscal 2014, we amended this facility to revive the extended cure period with respect to defaults relating to Celesio and the change of the debt to capital ratio from 56.5% to 65%.
