Debt and Financing Activities

Long-Term Debt

Our long-term debt includes both U.S. dollar and foreign currency denominated borrowings. At June 30, 2018 and March 31, 2018, $7,719 million and $7,880 million of total debt were outstanding, of which $1,127 million and $1,129 million were included under the caption “Current portion of long-term debt” within our condensed consolidated balance sheets.

Revolving Credit Facilities

We have a syndicated $3.5 billionfive-year senior unsecured revolving credit facility (the “Global Facility”), which has a $3.15 billion aggregate sublimit of availability in Canadian dollars, British pound sterling and Euros. The Global Facility matures on October 22, 2020. Borrowings under the Global Facility bear interest based upon the London Interbank Offered Rate, Canadian Dealer Offered Rate for credit extensions denominated in Canadian Dollars, a prime rate, or alternative overnight rates as applicable, plus agreed margins. 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 June 30, 2018, we were in compliance with all covenants. There were no borrowings outstanding under this facility during the first quarters of 2019 and 2018 and as of June 30, 2018 and March 31, 2018.

We also maintain bilateral credit lines primarily denominated in Euros with a total committed and uncommitted balance of $217 million as of June 30, 2018. Borrowings and repayments were not material during the first quarters of 2019 and 2018 and amounts outstanding under these credit lines were not material as of June 30, 2018 and March 31, 2018.

Commercial Paper

We maintain a commercial paper program to support our working capital requirements and for other general corporate purposes. Under the program, the Company can issue up to $3.5 billion in outstanding notes. During the first quarter of 2019, we borrowed $9.0 billion and repaid $7.0 billion under the program. Borrowings and repayments were not material during the first quarter of 2018. At June 30, 2018, there were $2.0 billion of commercial paper notes outstanding with a weighted average interest rate of 2.43%. At March 31, 2018, there were no commercial paper notes outstanding.
