(1)The stated rates on our fixed-rate property debt are between 2.4% to 5.7%.

(2)During the second quarter of 2022, we hedged $830 million of our floating rate debt through placement of floating to fixed rate swaps, which have been designated as cash flow hedges. These hedges lock $830 million of floating rate debt at an all in cost of 4.2%.

(3)The term loans bear interest at a 1-month Term Secured Overnight Financing Rate (“SOFR”) plus 1.00% and a SOFR adjustment of 10 basis points, based on our current credit rating. As of December 31, 2022, the weighted-average interest rate for our term loans, which is fixed via interest rate swaps beginning with the second quarter of 2022, was 4.1%. The term loans mature on the following schedule: $150 million mature on December 15, 2023, with two one-year extension options; $300 million mature on December 15, 2024, with a one-year extension option; $150 million mature on December 15, 2025; and $200 million mature on April 14, 2026.

(4)On May 2, 2022, we exercised the accordion feature on our revolving credit facility, increasing the revolving credit facility by $400 million to $1.0 billion. As of December 31, 2022, we had capacity to borrow up to $526.9 million under our revolving credit facility after consideration of undrawn letters of credit. The revolving credit facility bears interest at a 1-month Term SOFR plus 0.89%, based on our current credit rating, and a SOFR adjustment of 10 basis points. As of December 31, 2022, the weighted-average interest rate for our revolving credit facility was 5.3%.

(5)During the second quarter of 2022, we issued three tranches of guaranteed, senior unsecured notes, totaling $400 million. As of December 31, 2022, the weighted-average interest rate for senior unsecured notes was 4.3%.

Subsequent to December 31, 2022, and on a leverage neutral basis, AIR borrowed $320 million using 10-year fixed rate financing, bearing interest at 4.9%. Proceeds were used to refinance a floating rate loan and reduce borrowings by $230 million on our revolving credit facility. This transaction reduced floating rate debt not subject to interest rate caps or swaps to 4%, or

$150 million, and increased our weighted-average maturity by nine months. After this transaction, AIR has no debt maturing before the second quarter of 2025.

As of December 31, 2022, our fixed-rate property debt was secured by 23 apartment communities that had an aggregate net book value of $2.0 billion and our variable-rate property debt was secured by one apartment community that had an aggregate net book value of $171.0 million. Principal and interest on fixed-rate property debt are generally payable monthly or in monthly interest-only payments with balloon payments due at maturity. Principal and interest on variable-rate property debt are generally payable in monthly installments with balloon payments due at maturity.
