The notes are fully and unconditionally guaranteed by the Company. Interest on the notes is payable semi-annually. The terms of the unsecured notes include certain financial covenants that require the Operating Partnership to limit the amount of total debt and secured debt as a percentage of total asset value, as defined. In addition, the Operating Partnership must maintain a minimum ratio of unencumbered asset value to unsecured debt, as well as a minimum interest coverage level. As of June 30, 2020, the Company was in compliance with all such covenants.

In February 2019, the Company exercised the option under the existing credit agreement to increase the capacity of the unsecured revolving credit facility from $700 million to $1.0 billion. It may be expanded by up to an additional $200 million upon the satisfaction of certain conditions. The maturity date of the revolving credit facility is March 2022.

The unsecured revolving credit facility bears interest at a variable rate, at the Company’s option, based upon a base rate of one-, two-, three- or six-month LIBOR, plus, in each case, a spread based upon the Company’s investment grade rating from either Moody’s Investor Services, Inc. or Standard & Poor’s Rating Group. Additionally, the Company is required to pay a facility fee of 0.20% per annum on the $1.0 billion revolving credit facility. As of June 30, 2020, the revolving credit facility bore interest at a weighted average annual rate of 1.38% (0.18% + 1.00% spread + 0.20% facility fee), and availability under the revolving credit facility totaled $813.5 million.

The terms of the unsecured credit facility include certain restrictions and covenants, which limit, among other items, the incurrence of additional indebtedness and liens. The facility contains customary affirmative and negative covenants and also contains financial covenants that, among other things, require the Company to maintain certain maximum leverage ratios and minimum ratios of “EBITDA” (earnings before interest, taxes, depreciation and amortization) to fixed charges. The financial covenants also include a minimum asset value requirement, a maximum secured debt ratio, and a minimum unsecured debt service coverage ratio. As of June 30, 2020, the Company was in compliance with all such covenants.

The Company is currently party to an Unsecured Term Loan Credit Agreement (the “Term Loan Facility”) totaling $200 million which matures in June 2022. The agreement has an accordion feature that allows the Company to expand the amount by up to an additional $100 million, subject to the satisfaction of certain conditions. In November and December 2019, the Company entered into two interest rate swap contracts to hedge the variable rate cash flows associated with the LIBOR-based interest payments on the Term Loan Facility. The weighted average annual rate on the Term Loan Facility was 2.54% (1.44% + 1.10% spread) at June 30, 2020. The terms of the Term Loan Facility include certain restrictions and covenants consistent with those of the unsecured revolving credit facility discussed above. As of June 30, 2020, the Company was in compliance with all such covenants.
