The Company has a $2,250,000,000 revolving variable rate unsecured credit facility with a syndicate of banks (the "Credit Facility") which matures in September 2026. The interest rate that would be applicable to borrowings under the Credit Facility was 5.92% at June 30, 2023 and was composed of (i) the Secured Overnight Financing Rate ("SOFR") plus (ii) the current borrowing spread to SOFR of 0.825% per annum, which consisted of a 0.10% SOFR adjustment plus 0.725% per annum, assuming a daily SOFR borrowing rate. The borrowing spread to SOFR can vary from SOFR plus 0.65% to SOFR plus 1.40% based upon the rating of the Company's unsecured and unsubordinated long-term indebtedness. There is also an annual facility commitment fee of 0.125% of the borrowing capacity under the facility, which can vary from 0.10% to 0.30% based upon the rating of the Company's unsecured and unsubordinated long-term indebtedness. The Credit Facility contains a sustainability-linked pricing component which provides for interest rate margin and commitment fee reductions or increases by meeting or missing targets related to environmental sustainability, specifically greenhouse gas emission reductions, with the adjustment determined annually beginning in July 2023.

The availability on the Company's Credit Facility as of June 30, 2023 and December 31, 2022, respectively, was as follows (dollars in thousands):

(1)In addition, the Company had $51,832 and $48,740 outstanding in additional letters of credit unrelated to the Credit Facility as of June 30, 2023 and December 31, 2022, respectively.

The Company has an unsecured commercial paper note program (the “Commercial Paper Program”) with the maximum aggregate face or principal amount outstanding at any one time not to exceed $500,000,000. The Commercial Paper Program is backstopped by the Company's commitment to maintain available borrowing capacity under the Credit Facility in an amount equal to actual borrowings under the Commercial Paper Program.

During the six months ended June 30, 2023, the Company repaid $250,000,000 principal amount of its 2.85% unsecured notes at its maturity.

In the aggregate, secured notes payable mature at various dates from March 2027 through July 2066, and are secured by certain apartment communities (with a net carrying value of $1,166,698,000, excluding communities classified as held for sale, as of June 30, 2023).
