(1)    Balances are increased by $6.3 million and $5.3 million for fair value adjustments due to changes in benchmark interest rates related to these notes as of June 30, 2025 and December 31, 2024, respectively. See Note 7. "Derivative Financial Instruments and Hedging Activities," for further discussion.
(2)     The 2029 Notes have an effective annual interest rate of approximately 3.84% through June 2026, which includes the effect of a settled forward interest rate swap, and approximately 3.28% thereafter, for an all-in average effective rate of approximately 3.67%.
(3) Balances are decreased by unamortized debt discounts, debt issuance costs, and fair market value adjustments, net of $10.6 million and $13.3 million as of June 30, 2025 and December 31, 2024, respectively.
We have a $1.2 billion unsecured revolving credit facility which matures in August 2026, with two options to extend the facility at our election for two consecutive six-month periods and to expand the facility up to three times by up to an additional $500 million upon satisfaction of certain conditions. The interest rate on our unsecured revolving credit facility is based upon, at our option, (a) the daily or the one-, three-, or six-month Secured Overnight Financing Rate ("SOFR") plus, in each case, a spread based on our credit rating, or (b) a base rate equal to the higher of: (i) the Federal Funds Rate plus 0.50%, (ii) Bank of America, N.A.'s prime rate, (iii) Term SOFR plus 1.0%, and (iv) 1.0%. Advances under our unsecured revolving credit facility may be priced at the scheduled rates, or we may enter into bid rate loans with participating banks at rates below the scheduled rates. These bid rate loans have terms of 180 days or less and may not exceed the lesser of $600 million or the remaining amount available under our unsecured revolving credit facility. Our unsecured revolving credit facility is subject to customary financial covenants and limitations. We believe we are in compliance with all such financial covenants and limitations as of June 30, 2025 and through the date of this filing.
Our unsecured revolving credit facility provides us with the ability to issue up to $50 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our unsecured revolving credit facility, it does reduce the amount available. At June 30, 2025, we had no outstanding letters of credit issued under our unsecured revolving credit facility and had approximately $1.2 billion available under our unsecured revolving credit facility.
In February 2025, we established a commercial paper program under which we may issue short-term, unsecured commercial paper notes (the "Notes") under the exemption from registration contained in Section (4)(a) of the Securities Act of 1933, as amended. Amounts available under the commercial paper program may be borrowed, repaid, and reborrowed from time to time, with the aggregate face or principal amount of the Notes outstanding under the commercial paper program at any
time not to exceed $600 million. The Notes will have maturities of up to 397 days from the date of issue. The Notes will rank at least equal in priority to all of the Company's other unsecured and unsubordinated indebtedness. The net proceeds of the issuances of the Notes are expected to be used for general corporate purposes, which may include property acquisitions and development in the ordinary course of business, capital expenditures, and working capital. We currently plan to use our unsecured revolving credit facility as a liquidity backstop for borrowings under the commercial paper program. The commercial paper issued during the six months ended June 30, 2025 had original maturities of less than 30 days.
We had outstanding floating rate debt of approximately $1.1 billion and $721.2 million at June 30, 2025 and December 31, 2024, respectively, which includes senior unsecured notes payable due in 2026 which have been converted to floating rate debt through the issuance of an interest rate swap. The weighted average interest rate on our outstanding floating rate debt was approximately 5.1% and 5.6% as of June 30, 2025 and December 31, 2024, respectively.
Our indebtedness had a weighted average maturity of approximately 5.1 years at June 30, 2025. The table below is a summary of the maturity dates of our outstanding debt and principal amortizations, and the weighted average interest rates on such debt, at June 30, 2025:
