10. DEBT

The annualized weighted average cost of debt for the six months ended March 31, 2026 and 2025, inclusive of the fee on the undrawn commitment and amendment costs on the Truist Credit Facility and amortized upfront fees on 2026 Notes, 2026 Notes-2 and 2029 Notes, was 6.3% and 6.1%, respectively. As of March 31, 2026, in accordance with the 1940 Act, with certain limited exceptions, we are only allowed to borrow amounts such that we are in compliance with a 150% asset coverage ratio after such borrowing.

On February 5, 2019, our stockholders 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, or "SBCAA") as approved by our board of directors on November 13, 2018. As a result, the asset coverage requirement applicable to us 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. As of March 31, 2026 and September 30, 2025, our asset coverage ratio, as computed in accordance with the 1940 Act, was 175% and 163%, respectively.
