Asset coverage ratio, Description On October 17, 2025, the Company’s board of trustees approved the application of the modified asset coverage requirements set forth in Section 61(a)(2) of the 1940 Act, as amended by the Consolidated Appropriations Act of 2018 (which includes the Small Business Credit Availability Act). As a result, the asset coverage requirement applicable to the Company for senior securities was reduced from 200% (i.e., $1 of debt outstanding for each $1 of equity) to 150% (i.e., $2 of debt outstanding for each $1 of equity), subject to compliance with certain disclosure requirements.
