We are exposed to certain market risks, of which one of the most significant is a change in interest rates. Our future earnings, cash flows and fair values relevant to financial instruments are dependent upon prevalent market interest rates. Our primary market risk results from our indebtedness, which bears interest at fixed and variable rates. The fair values of our debt obligations are affected by changes in the market interest rates. Unless we have entered into interest rate swaps or other derivatives to fix the interest rates, increases in interest rates can result in increased interest expense under our 2025 Credit Facility, 2024 Unsecured Term Loan, Commercial Paper Program, 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. We manage our market risk by matching long-term leases with long-term, fixed-rate, non-recourse debt of similar duration. We continue to follow a conservative strategy of generally pre-leasing development projects on a long-term basis to creditworthy clients in order to achieve the most favorable construction and permanent financing terms.
As of June 30, 2026, 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 approximately $2.3 billion of outstanding indebtedness bore interest at variable rates, including approximately $800.0 million of unsecured term loans, $750.0 million of borrowings under the Commercial Paper Program, and approximately $800.0 million of secured debt. However, we have entered into interest rate swaps with notional amounts aggregating $600.0 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). Therefore, as of June 30, 2026, we effectively had approximately $1.7 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, 2026.
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, 2026, the weighted-average stated interest rate on the fixed rate debt stated above was 3.73% per annum. At June 30, 2026, the weighted-average stated interest rate on our variable rate debt, including the effect of the interest rate swaps, was 4.85% per annum. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $5.9 million and $11.8 million for the three and six months ended June 30, 2026, respectively.

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.
