Debt Disclosure [Abstract]
Debt and Financing Activities	Debt and Financing Activities Long-Term Debt Our long-term debt includes both U.S. dollar and foreign currency (primarily Euro) denominated borrowings. At December 31, 2015 and March 31, 2015, $8,711 million and $9,709 million of total long-term debt were outstanding, of which $996 million and $1,529 million were included under the caption “Current portion of long-term debt” within the condensed consolidated balance sheets. At March 31, 2015, we had a term loan with an outstanding balance of $89 million (or £60 million). During the first quarter of 2016, we repaid this term loan for $93 million. During the second quarter of 2016, we repaid our $400 million floating rate notes due September 10, 2015 at maturity. During the third quarter of 2016, we repaid our $500 million 0.95% notes due December 4, 2015 at maturity. Revolving Credit Facilities We had a syndicated $1.3 billion five-year senior unsecured revolving credit facility, which was to expire in September 2016. We also had a syndicated €500 million five-year senior unsecured revolving credit facility, which was to expire in February 2018. Both revolving credit facilities were terminated in connection with the execution of a new $3.5 billion revolving credit facility in October 2015, as discussed below. There were no borrowings under these facilities during the first nine months of 2016 and 2015. As of March 31, 2015, there were no amounts outstanding under these facilities. During the third quarter of 2016, we entered into a syndicated $3.5 billion five-year senior unsecured revolving credit facility (the “Global Facility”). The Global Facility has a $3.15 billion aggregate sublimit of availability in Canadian dollars, British pounds sterling and Euros. The remaining terms and conditions of the Global Facility are substantially similar to those previously in place under the $1.3 billion revolving credit facility which was terminated in October 2015. There were no borrowings outstanding under this facility during the third quarter of 2016, and as of December 31, 2015. The Global Facility contains a financial covenant which obligates the Company to maintain a debt to capital ratio of no greater than 65% and other customary investment grade covenants. If we do not comply with these covenants, our ability to use the Global Facility may be suspended and repayment of any outstanding balances under the Global Facility may be required. At December 31, 2015, we were in compliance with all covenants. We also maintain bilateral credit lines primarily denominated in Euros with a total committed and uncommitted balance of $1.1 billion. During the first nine months of 2016 and 2015, we borrowed $631 million and $222 million and repaid $633 million and $181 million under these credit lines primarily related to short-term borrowings. These credit lines have interest rates ranging from 0.18% to 6%. As of December 31, 2015 and March 31, 2015, there were $29 million and $29 million outstanding under these credit lines. Accounts Receivable Facilities In connection with the execution of the Global Facility, we also terminated an accounts receivable sales facility (the “AR Facility”) with a committed balance of $1.35 billion during the third quarter of 2016. There were no borrowings outstanding under the AR Facility during the first nine months of 2016 (prior to the date of termination) and 2015, and as of March 31, 2015. The AR Facility contained requirements relating to the performance of the accounts receivable and covenants relating to the Company. If we did not comply with these covenants, our ability to use the AR Facility would have been suspended and repayment of any outstanding balances under the AR Facility would have been required. At March 31, 2015, we were in compliance with all covenants. We also have accounts receivable factoring facilities (the “Factoring Facilities”) denominated in foreign currencies with a total committed balance of $6 million. During the first nine months of 2016 and 2015, we borrowed $901 million and $2,200 million and repaid $1,037 million and $2,154 million in short-term borrowings under these facilities. At December 31, 2015 and March 31, 2015, there were $6 million and $135 million in secured borrowings outstanding under these facilities. The Factoring Facilities will expire through April 2016. Commercial Paper We maintain a commercial paper program to support our working capital requirements and for other general corporate purposes. In November 2015, we replaced the existing program with a new commercial paper program through which the Company can issue up to $3.5 billion in outstanding notes. We had no outstanding obligations under either program during the nine months ended December 31, 2015 and 2014, and as of December 31, 2015 and March 31, 2015.
