[3] Generally, the interest rate on floating interest rate investments is at benchmark rate plus spread, subject to an interest rate floor. The borrower has an option to choose the benchmark rate, such as the Secured Overnight Financing Rate including adjustment, if any (“S”) or the U.S. Prime Rate (“P”). The spread may change based on the type of rate used. The terms in the Consolidated Schedule of Investments disclose the actual interest rate in effect as of the reporting period. S loans are typically indexed to 30-day, 90-day or 180-day rates (1M, 3M or 6M, respectively) at the borrower’s option. As of June 30, 2026, rates for 1M S, 3M S and 6M S are 3.65%, 3.73%, and 3.85%, respectively. As of June 30, 2026, the P was 6.75%. For investments with multiple reference rates or alternate base rates, the interest rate shown is the weighted average interest rate in effect at June 30, 2026.
