The issued notes pay interest semi-annually and carry a negative pledge. Term credit facility During the nine months ended September 30, 2025, the Company entered into, and fully repaid, a U.S. $500 million unsecured non-revolving term credit facility (the "term facility"). The Company presents draws and repayments on its term facility in the Interim Consolidated Statements of Cash Flows on a net basis. Credit facility Effective August 20, 2025, the Company amended its revolving credit facility agreement (the "facility") to extend the maturity dates of its five-year U.S. $1.1 billion facility and two-year U.S. $1.1 billion facility to June 25, 2030 and June 25, 2027, respectively. As at September 30, 2025, the facility was undrawn. As at December 31, 2024, the Company had U.S. $200 million ($288 million) drawn from the two-year U.S. $1.1 billion facility, which was subsequently repaid in full during the first quarter of 2025. The Company presents draws and repayments on the facility in the Interim Consolidated Statements of Cash Flows on a net basis. Commercial paper program The Company has a commercial paper program, under which it may issue up to a maximum aggregate principal amount of U.S. $1.5 billion in the form of unsecured promissory notes. This commercial paper program is backed by the U.S. $2.2 billion facility. As at September 30, 2025, the Company had total commercial paper borrowings outstanding of U.S. $1,138 million ($1,584 million) recognized in "Long-term debt maturing within one year" on the Company's Interim Consolidated Balance Sheets (December 31, 2024 - U.S. $1,102 million ($1,586 million)). The weighted-average interest rate on these borrowings as at September 30, 2025 was 4.43% (December 31, 2024 - 4.75%). The Company presents issuances and repayments of commercial paper, all of which have a maturity of less than 90 days, in the Interim Consolidated Statements of Cash Flows on a net basis.
