(1)

Represents per share net investment income for the period, based upon weighted average shares outstanding.

(2)

Net realized and unrealized gains/(losses) include rounding adjustments to reconcile change in net asset value per share.

(3)

Management monitors available taxable earnings, including net investment income and realized capital gains, to determine if a tax return of capital may occur for the year. To the extent the Company’s taxable earnings fall below the total amount of the Company’s distributions for that fiscal year, a portion of those distributions may be deemed a tax return of capital to the Company’s stockholders. The ultimate tax character of the Company’s earnings cannot be determined until tax returns are prepared after the end of the fiscal year. The amounts and sources of distributions reported are only estimates (based on an average of the reported tax character historically) and are not being provided for U.S. tax reporting purposes. For each of the three-month periods ended June 30, 2026 and 2025, distributions were $0.105 per share and are presented as $0.11 per share due to rounding.

(4)

Total return based on market value equals the increase or decrease of ending market value over beginning market value, plus distributions, divided by the beginning market value, assuming distribution reinvestment prices obtained under the Company’s distribution reinvestment plan. Total return is not annualized.

(5)

Total return based on net asset value equals the increase or decrease of ending net asset value over beginning net asset value, plus distributions, divided by the beginning net asset value. Total return is not annualized.

(6)

Annualized and adjusted for one-time excise tax reversals in the current quarter.

(7)

Portfolio turnover rate is calculated using the lesser of the year-to-date investment sales and debt repayments or year-to-date investment purchases over the average of the total investments at fair value.
