11. Debt and Credit Agreements

Short-Term Borrowings

We meet our short-term liquidity requirements primarily through the issuance of commercial paper. We may use our credit facility for general corporate purposes, including meeting short-term funding requirements and the issuance of letters of credit.

Credit Agreements

In June 2024, we amended our existing $3.5 billion revolving credit facility (RCF), to increase the available aggregate commitment to $4.5 billion and extend the maturity date from January 2027 to June 2029. The RCF may be drawn down in the form of loans and/or to support commercial paper and letters of credit issuances.

The RCF fixed facility fee rate is 0.175% and borrowings under the RCF bear interest at a rate based upon either the Daily Simple SOFR rate or a Term SOFR rate, plus an adder based upon our credit ratings. The adders for the Daily Simple SOFR based borrowings and Term SOFR borrowings are 7.5 basis points and 107.5 basis points, respectively. The letters of credit bear interest at a rate of 1.075%.

If we were to lose our investment grade credit rating, the maximum adders for Daily Simple SOFR rate borrowings and Term SOFR rate borrowings would be 100 basis points and 200 basis points, respectively. The credit agreements also require us to pay facility fees based upon the aggregate commitments. The fees vary depending upon our credit rating.

As of June 30, 2024 and December 31, 2023, we had the following aggregate bank commitments, credit facility borrowings and available capacity under our respective credit facilities:

(a)Our commercial paper program is supported by the revolving credit agreement. In order to maintain our commercial paper program in the amounts indicated above, we must have a credit facility in place, at least equal to the amount of our commercial paper program. As of June 30, 2024 and December 31, 2023, the maximum program size of our commercial paper program was $4.5 billion and $3.5 billion, respectively. We do not issue commercial paper in an aggregate amount exceeding the then available capacity under our credit facility. The weighted average interest rate on commercial paper borrowings was 5.57% and 5.66% as of June 30, 2024 and December 31, 2023, respectively.

(b)In March 2024, we initiated a new bilateral credit agreement for $200 million, with no maturity date. In May 2024, we initiated a new bilateral credit agreement for $150 million, with no maturity date. In June 2024, a bilateral credit agreement initiated in November 2019 was extended for an additionaltwo years to June 2026.

(c)The maximum amount of the bank commitment is not to exceed $971 million. The aggregate available capacity of the facility is subject to market fluctuations based on the value of U.S. Treasury Securities which determines the amount of collateral held in the trust. We may post additional collateral to borrow up to the maximum bank commitment. As of June 30, 2024 and December 31, 2023, without posting additional collateral, the actual availability of facility, prior to outstanding letters of credit was $908 million and $911 million, respectively.
