Bank Credit Facility

The Company has a $640 million senior unsecured revolving credit facility with an uncommitted accordion feature that could increase the size of the facility to $1 billion, subject to certain conditions and availability of additional bank commitments. The facility includes bank commitments of $575 million maturing on December 18, 2029 and $65 million maturing on October 28, 2026. The facility also provides for the issuance of letters of credit with a sublimit equal to the greater of $100 million and 50% of the total revolving credit commitments. Borrowings under the revolving credit facility are subject to a borrowing base calculation based on the book value of the Company's real estate assets and unrestricted cash. Letters of credit issued under the facility reduce the available borrowing capacity. At June 30, 2025, there were no borrowings outstanding and $37.2 million of letters of credit issued under the revolving credit facility, resulting in available capacity of $602.8 million.
The revolving credit facility is guaranteed by the Company’s wholly-owned subsidiaries that are not immaterial subsidiaries and have not been designated as unrestricted subsidiaries. The revolving credit facility includes customary affirmative and negative covenants, events of default and financial covenants. The financial covenants require a minimum level of tangible net worth, a minimum level of liquidity and a maximum allowable leverage ratio. These covenants are measured as defined in the credit agreement governing the facility and are reported to the lenders quarterly. A failure to comply with these financial covenants could allow the lending banks to terminate the availability of funds under the revolving credit facility or cause any outstanding borrowings to become due and payable prior to maturity. At June 30, 2025, the Company was in compliance with all of the covenants, limitations and restrictions of its revolving credit facility.

Senior Notes

The Company has outstanding senior notes as described below that were issued pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the "Securities Act"). The notes represent senior unsecured obligations that rank equally in right of payment to all existing and future senior unsecured indebtedness and may be redeemed prior to maturity, subject to certain limitations and premiums defined in the indenture agreements. The notes are guaranteed by each of the Company's subsidiaries to the extent such subsidiaries guarantee the Company's revolving credit facility.

In March 2025, the Company issued $500 million principal amount of 6.5% senior notes due March 15, 2033 (the "2033 notes"), with interest payable semiannually. The annual effective interest rate of the 2033 notes after giving effect to the amortization of financing costs is 6.7%. The net proceeds from this issuance were primarily used to fund the Company's tender offer to purchase any and all of its outstanding $400 million principal amount of 3.85% senior notes due 2026 (the "2026 notes"), of which $329.4 million aggregate principal amount was tendered. The repurchase price of $333.4 million included accrued and unpaid interest of $4.2 million. The Company recognized a $1.1 million loss on extinguishment of debt upon repurchase of the notes.

At any time prior to March 15, 2028, the Company may, on one or more occasions, redeem up to 40% of the aggregate principal amount of the 2033 notes with the net cash proceeds from certain equity offerings at a redemption price of 106.5% of the principal amount of the 2033 notes being redeemed. At any time prior to March 15, 2028, the Company may redeem some or all of the 2033 notes at a redemption price of 100% of the principal amount thereof plus a specified “make whole” premium described in the indenture. The Company also has the option, at any time on or after March 15, 2028 to redeem some or all of the 2033 notes at 103.25% of their principal amount plus any accrued and unpaid interest. In accordance with the indenture, the redemption price decreases annually thereafter and the 2033 notes can be redeemed at par on or after March 15, 2030 through maturity.

The Company's remaining $70.6 million principal amount of 2026 notes mature May 15, 2026 with interest payable semiannually. The 2026 notes can be redeemed at par after May 15, 2025 through maturity. The annual effective interest rate of the 2026 notes after giving effect to the amortization of financing costs is 4.1%.

The Company's $300 million principal amount of 5.0% senior notes (the "2028 notes") mature March 1, 2028 with interest payable semiannually. Until March 1, 2026, the 2028 notes may be redeemed at 100.833% of their principal amount plus any accrued and unpaid interest, and the 2028 notes can be redeemed at par on or after March 1, 2026 through maturity. The annual effective interest rate of the 2028 notes after giving effect to the amortization of financing costs is 5.2%.

The indentures governing the senior notes require that, upon the occurrence of both a change of control and a rating decline (as defined in each indenture), the Company offer to purchase the applicable series of notes at 101% of their principal amount, plus accrued and unpaid interest. Under the indentures governing the 2026 notes and 2028 notes, if the Company or its restricted subsidiaries dispose of assets, under certain circumstances, the Company will be required to either invest the net cash proceeds from such asset sales in its business within a specified period of time, repay certain senior secured debt or debt of its non-guarantor subsidiaries, or make an offer to purchase a principal amount of such notes equal to the excess net cash proceeds at a purchase price of 100% of their principal amount.
The indentures governing the 2026 notes and 2028 notes contain covenants that, among other things, restrict the ability of the Company and its restricted subsidiaries to pay dividends or distributions, repurchase equity, prepay subordinated debt and make certain investments; incur additional debt or issue mandatorily redeemable equity; incur liens on assets; merge or consolidate with another company or sell or otherwise dispose of all or substantially all of the Company’s assets; enter into transactions with affiliates; and allow to exist certain restrictions on the ability of subsidiaries to pay dividends or make other payments. The indenture governing the 2033 notes contains certain covenants that, among other things, restrict the ability of the Company and its restricted subsidiaries to create certain liens on assets; engage in certain sale and leaseback transactions; and merge or consolidate with another company or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the Company’s assets. At June 30, 2025, the Company was in compliance with all of the limitations and restrictions associated with its senior note obligations.

Effective April 30, 2020, the Board of Directors authorized the repurchase of up to $30 million of the Company’s debt securities. The authorization has no expiration date. All of the $30 million authorization was remaining at June 30, 2025.

Other Note Payable

In December 2023, the Company issued a note payable of $9.9 million as part of a transaction to acquire real estate for development. The note is non-recourse and is secured by the underlying real estate, accrues interest at 4.0% per annum and matures in December 2025.
