[1] Net investment income/(loss) based on total weighted average common stock outstanding equals $2.51 and $1.86 per share for the nine months ended June 30, 2026 and 2025, respectively.
[2] The amount shown at this caption is the balancing amount derived from the other figures in the schedule. The amount shown at this caption for a share outstanding throughout the period may not agree with the repurchase of common stock because of the timing of repurchase of the Company’s shares.
[3] Total return is historical and assumes changes in share price, reinvestments of all dividends and distributions at prices obtained under the Company’s dividend reinvestment plan, and no sales charge for the period. Calculation is not annualized.
[4] Total return is historical and assumes changes in NAV, reinvestments of all dividends at prices obtained under the Company’s dividend reinvestment plan, and no sales charges for the period. Calculation is not annualized.
[5] Ratios are annualized during interim periods.
[6] Total amount of each class of senior securities outstanding at the end of the period excluding debt issuance costs.
[7] Represents the impact of the non-recurring fees as a percentage of total investment income.
[8] Based on daily weighted average carrying value of debt outstanding during the period.
[9] Asset coverage per unit is the ratio of the carrying value of our total consolidated assets, less all liabilities and indebtedness not represented by senior securities, to the aggregate amount of senior securities representing indebtedness. Asset coverage per unit is expressed in terms of dollar amounts per $1,000 of indebtedness. As of June 30, 2026, the Company’s asset coverage was 207.0% after giving effect to leverage and therefore the Company’s asset coverage was above 200%, the minimum asset coverage requirement under the 1940 Act presently applicable to the Company.
