The BofA Credit Agreement contains customary affirmative and negative covenants for credit facilities of this type, including limitations with respect to indebtedness, liens, investments, mergers and acquisitions, disposition of assets, use of net cash proceeds from the disposition of property, assets and equity issuances, mandatory prepayments, the requirement to have certain subsidiaries provide guarantees, the requirement to pledge our equity interests in certain subsidiaries as collateral, changes in business, certain restricted payments, repurchases and redemptions of our common stock, going concern qualifications to our financial statements, and transactions with affiliates. In addition, the BofA Credit Agreement also restricts our ability to make quarterly dividend distributions that exceed $0.01 per share of our common stock; provided, however, that notwithstanding such restriction, we are permitted to make dividend distributions based on our good faith estimate of projected or estimated taxable income or otherwise as necessary to retain our status as a real estate investment trust, to meet the distribution requirements of Section 857 of the Internal Revenue Code or to eliminate any income or excise taxes to which we would otherwise be subject. The BofA Credit Agreement also contains financial covenants that require us to maintain a minimum tangible net worth, a maximum leverage ratio, a maximum secured leverage ratio, a maximum secured recourse leverage ratio, a minimum fixed charge coverage ratio, a maximum unencumbered leverage ratio, and minimum unsecured interest coverage. We were in compliance with the BofA Term Loan financial covenants as of March 31, 2024.
The BofA Credit Agreement provides for customary events of default with corresponding grace periods, including failure to pay any principal or interest when due, failure to comply with the provisions of the BofA Credit Agreement, certain cross defaults and a change in control (as defined in the BofA Credit Agreement). In the event of a default by us, the administrative agent may, and at the request of the requisite number of lenders shall, declare all obligations under the BofA Credit Agreement immediately due and payable and enforce any and all rights of the lenders or BofA under the BofA Credit Agreement and related documents. For certain events of default related to bankruptcy, insolvency, and receivership, all of our outstanding obligations will become immediately due and payable.
