Bank Credit Facility

The Company has a $380 million senior unsecured revolving credit facility with an uncommitted accordion feature that could increase the size of the facility to $570 million, subject to certain conditions and availability of additional bank commitments. 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 revolving credit commitment. 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, 2020, there were no borrowings outstanding and $31.6 million of letters of credit issued under the revolving credit facility, resulting in available capacity of $348.4 million. There were no borrowings or repayments under the facility during the nine months ended June 30, 2020.

In October 2019, the revolving credit facility was amended to extend its maturity date to October 2, 2022. The maturity date may be extended by up to one year on up to two additional occasions, subject to the approval of lenders holding a majority of the commitments.

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, 2020, the Company was in compliance with all of the covenants, limitations and restrictions of its revolving credit facility.

Senior Notes

In February 2020, the Company issued $300 million principal amount of 5.0% senior notes pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (Securities Act). The notes mature March 1, 2028 with interest payable semi-annually and represent senior unsecured obligations that rank equally in right of payment to all existing and future senior unsecured indebtedness. The notes may be redeemed prior to maturity, subject to certain limitations and premiums defined in the indenture agreement. On or after March 1, 2023, the notes may be redeemed at 102.5% of their principal amount plus any accrued and unpaid interest. In accordance with the indenture, the redemption price decreases annually thereafter and the notes can be redeemed at par on or after March 1, 2026 through maturity. The notes are guaranteed by each of the Company's subsidiaries to the extent such subsidiaries guarantee the Company's revolving credit facility. The annual effective interest rate of the notes after giving effect to the amortization of financing costs is 5.2%. The Company also has $350 million principal amount of 8.0% senior notes due 2024 outstanding.

In March 2020, the Company repaid $118.9 million principal amount of its 3.75% convertible senior notes in cash at maturity.

The indentures governing the senior notes require that, upon the occurrence of both a change of control and a rating decline (each as defined in the indentures), the Company offer to purchase the notes at 101% of their principal amount. 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 the notes equal to the excess net cash proceeds at a purchase price of 100% of their principal amount. The indentures 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. At June 30, 2020, 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, 2020.
