(3) Based upon the net assets attributable to the common shares as of August 29, 2025, after giving effect to the anticipated net proceeds of this offering. Assumes the Fund sells 6,004,804 common shares at an offering price of $12.49 (the last reported sale price per common share of the Fund on the NYSE as of August 29, 2025). The price per common share may be greater or less than the price assumed herein, depending on the market price of the common shares at the time of any sale. There is no guarantee that there will be any sales of common sha

res

pursuant to this prospectus supplement and the accompanying prospectus. The number of common shares actually sold pursuant to this prospectus supplement and the accompanying prospectus may be less than as assumed herein.

(4) The Adviser will receive a monthly management fee at an annual rate of 1.10% of the average daily value of the Fund’s Managed Assets. “Managed Assets” means the total assets of the Fund (including any assets attributable to borrowings for investment purposes) minus the sum of the Fund’s accrued liabilities (other than liabilities representing borrowings for investment purposes). Consequently, since the Fund has borrowings outstanding, the management fee as a percentage of net assets attributable to common shares is higher than if the Fund did not utilize leverage.

(5) Assumes the use of leverage through a credit facility and mandatory redeemable preferred stock (“MRPS”) representing 27.3% of Managed Assets at an annual interest rate expense to the Fund of 3.9%, which is based on the weighted average interest rate currently applicable under the Fund’s existing credit facility as of August 29, 2025, and the dividends payable on the MRPS at an annual dividend rate equal to 3.81%. The Fund may use other forms of leverage, which may be subject to different interest expenses than those estimated above. The extent of the Fund’s assets attributable to leverage following an offering, and the actual amount of interest expense borne by the Fund will vary over time (perhaps significantly) in accordance with the level of the Fund’s use of leverage and variations in market interest rates.

(6) The “Other Expenses” shown in the table above and related footnotes are based upon estimated expenses for the current fiscal year assuming completion of the proposed issuances.

Purpose of Fee Table , Note [Text Block]

The following tables are intended to assist you in understanding the various costs and expenses directly or indirectly associated with investing in our common shares as a percentage of net assets attributable to common shares. Amounts are for the current fiscal year after giving effect to anticipated net proceeds of the offering, assuming that the Fund incurs the estimated offering expenses.

Other Expenses, Note [Text Block]

The “Other Expenses” shown in the table above and related footnotes are based upon estimated expenses for the current fiscal year assuming completion of the proposed issuances.

Management Fee not based on Net Assets, Note [Text Block]

The Adviser will receive a monthly management fee at an annual rate of 1.10% of the average daily value of the Fund’s Managed Assets. “Managed Assets” means the total assets of the Fund (including any assets attributable to borrowings for investment purposes) minus the sum of the Fund’s accrued liabilities (other than liabilities representing borrowings for investment purposes). Consequently, since the Fund has borrowings outstanding, the management fee as a percentage of net assets attributable to common shares is higher than if the Fund did not utilize leverage.
