U.S. Committed Credit Facilities

On 26 March 2026, we amended our existing 364-day $500 revolving credit agreement to extend its maturity date from 26 March 2026 to 25 March 2027. The amendment also provides that if we elect to convert the facility into a term loan, the maturity date of the term loan would be 25 March 2028. Fees incurred in connection with the amendment were not material.

We also maintain a five-year $3.0 billion revolving credit agreement that matures on 31 March 2029. Both the 364-day agreement and the five-year agreement are syndicated committed facilities that provide a source of liquidity and support our commercial paper program through the availability of senior unsecured debt to us and certain of our subsidiaries. No borrowings were outstanding under either of the agreements as of 31 March 2026 or 30 September 2025.

Repayments

During the first quarter of fiscal year 2026, we repaid at maturity $550.0 aggregate principal amount of our 1.50% senior notes due October 2025, plus accumulated and unpaid interest through the maturity date.
