Debt and lines of credit Debt and lines of credit
Short-term borrowings
We maintain a line of credit to provide additional liquidity through bank loans and, if necessary, to support commercial paper borrowings. As of June 30, 2025, the aforementioned line of credit was a variable-rate, revolving credit facility from a consortium of investment-grade banks that allows us to borrow up to $1 billion until March 2026. The interest rate on borrowings under this credit facility, if drawn, is indexed to the applicable Term Secured Overnight Financing Rate (Term SOFR). As of June 30, 2025, our credit facility was undrawn, and we had no commercial paper outstanding.
Long-term debt
In May 2025, we issued two series of senior unsecured notes for an aggregate principal amount of $1.20 billion, consisting of $550 million of 4.50% notes due in 2030 and $650 million of 5.10% notes due in 2035. We incurred $6 million of issuance and other related costs. The proceeds of the offering were $1.20 billion, net of the original issuance discounts, which will be used for general corporate purposes.
In March 2025, we retired $750 million of maturing debt.
