Item 3. Quantitative and Qualitative Disclosures about Market Risk.

We are exposed to certain market risks, one of the most predominant of which is a change in interest rates. Unless we have entered into interest rate swaps or other derivatives to fix the interest rate, increases in interest rates can result in increased interest expense under our 2021 Credit Facility, 2023 Unsecured Term Loan, unsecured commercial paper, certain mortgage loans and other debt that bears interest at variable rates. Increases in interest rates can also result in increased interest expense when our fixed rate debt matures and needs to be refinanced.

As of June 30, 2024, approximately $13.3 billion of our indebtedness bore interest at fixed rates and therefore the fair value of these instruments is not affected by changes in the market interest rates. The remaining $2.1 billion of outstanding indebtedness bore interest at variable rates, including $700.0 million under the 2023 Unsecured Term Loan, $500.0 million of unsecured commercial paper borrowings and $900.0 million of secured debt. However, we entered into interest rate swaps with notional amounts aggregating $900.0 million for our secured debt, thus fixing the interest rates for all, or a portion of the applicable debt term (See Note 7 to the Consolidated Financial Statements for information pertaining to interest rate swap contracts in place as of June 30, 2024 and their respective fair values). Therefore, as of June 30, 2024, we have $1.2 billion of variable rate debt outstanding.

The following table presents our aggregate debt obligations carrying value, estimated fair value and where applicable, the corresponding weighted-average GAAP interest rates sorted by maturity date as of June 30, 2024.

The table below does not include our unconsolidated joint venture debt. For a discussion concerning our unconsolidated joint venture debt, including interest rate swaps, see Note 5 to the Consolidated Financial Statements and “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Investment in Unconsolidated Joint Ventures - Secured Debt.”

At June 30, 2024, the weighted-average stated interest rates on the fixed rate debt stated above was 3.68% per annum. At June 30, 2024, our outstanding variable rate debt totaled $2.1 billion, of which $900.0 million was subject to interest rate swaps. At June 30, 2024, the weighted-average stated interest rate on our variable rate debt, including the effect of the interest rate swaps, was 4.49% per annum. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $5.3 million and $10.5 million for the three and six months ended June 30, 2024.

Our use of derivative instruments also involves certain additional risks such as counterparty credit risk, the enforceability of hedging contracts and the risk that unanticipated and significant changes in interest rates will cause a significant loss of basis in the contract. We believe that there is a low likelihood that these counterparties will fail to meet their obligations and we minimize our exposure by limiting counterparties to major banks who meet established credit and capital guidelines. There can be no assurance that we will adequately protect against the foregoing risks.

The fair value amounts were determined solely by considering the impact of hypothetical interest rates on our financial instruments. Due to the uncertainty of specific actions, we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure.
