Supplemental Prospectus (Form 424B3)

(1)  Represents the estimated commission with respect to the Common Shares being sold in this offering.

(2)  Offering expenses payable by the Fund will be deducted from the proceeds, before expenses, to the Fund.

(3)  Shareholders who participate in the Fund's Dividend Reinvestment and Optional Cash Purchase Plan (the "Plan") may be subject to fees on certain transactions. The Plan Agent's (as defined under "Dividend Reinvestment and Optional Cash Purchase Plan" in the accompanying Prospectus) fees for the handling of the reinvestment of dividends will be paid by the Fund; however, participating shareholders will pay a $0.02 per share fee incurred in connection with open-market purchases in connection with the reinvestment of dividends, capital gains distributions and voluntary cash payments made by the participant, which will be deducted from the value of the dividend. For optional share purchases, shareholders will also be charged a $2.50 fee for automatic debits from a checking/savings account, a $5.00 one-time fee for online bank debit and/or $5.00 for check. Shareholders will be subject to $0.12 per share fee and either a $10.00 fee (for batch orders) or $25.00 fee (for market orders) for sales of shares held in a dividend reinvestment account. Per share fees include any applicable brokerage commissions the Plan Agent is required to pay. For more details about the Plan, see "Dividend Reinvestment and Optional Cash Purchase Plan" in the accompanying Prospectus.

(4)  Based upon average net assets attributable to our Common Shares during the six months ended April 30, 2026, after giving effect to the anticipated net proceeds of this offering. Assumes the Fund sells 2,412,141 Common Shares at an offering price of $11.96 (the last reported sale price per Common Share on the NYSE as of April 30, 2026). 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 Shares 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.

(5)  The Adviser receives a monthly fee at an annual rate of 1.00% of the Fund's average daily Managed Assets. The advisory fee percentage calculation assumes the use of leverage by the Fund as discussed in note (6). To derive the annual advisory fee as a percentage of the Fund's net assets (which are the Fund's total assets less all of the Fund's liabilities), the Fund's average Managed Assets for the semi-annual period ended April 30, 2026 (plus the anticipated net proceeds of this offering as described in note (4)), were multiplied by the annual advisory fee rate and then divided by the Fund's average net assets for the same period (plus the anticipated net proceeds of this offering as described in note (4)).

(6)  The percentage in the table is based on average total borrowings of $42,944,000 (the balance outstanding under the Fund's secured, uncommitted line of credit with BNP Paribas as of April 30, 2026, representing approximately 10.4% of the Fund's Managed Assets) and an average interest rate during the six months ended April 30, 2026, of 4.78%. There can be no assurances that the Fund will be able to obtain such level of borrowing (or to maintain its current level of borrowing), that the terms under which the Fund borrows will not change, or that the Fund's use of leverage will be profitable. The Fund currently intends during the next twelve months to maintain a similar proportionate amount of borrowings but may increase such amount to 33 1/3% of the average daily value of the Fund's total assets.

(7)  "Other expenses" include, among others, compensation of the Fund's Independent Trustees equal to 0.02%, which are excluded from the Fund's contractual limitation effective July 1, 2026, as described in note (8).

(8)  The Adviser has contractually agreed to waive fees and/or reimburse expenses in order to limit total operating expenses of the Fund (excluding any leverage costs, taxes, interest, brokerage commissions, compensation of the Fund's Independent Trustees and any non-routine expenses) as a percentage of net assets to 1.40% per annum of the Fund's average daily net assets on an annualized basis. Following approval of the Independent Trustees, on July 1, 2026, the Adviser and the Fund agreed to amend and restate the contractual limitation, such that compensation of the Fund's Independent Trustees is excluded from the expense limitation effective for the period beginning July 1, 2026. Accordingly, the expense information in the table has been restated to reflect current fees. This contractual limitation may not be terminated before October 31, 2027 without the approval of the Independent Trustees. The Fund may repay any such waiver or reimbursement from the Adviser, within three years of the waiver or reimbursement, provided that such repayments do not cause the Fund to exceed (i) the lesser of the applicable expense limitation in the contract at the time the fees were limited or expenses are paid or (ii) the applicable expense limitation in effect at the time the expenses are being recouped by the Adviser.

The purpose of the table above and the example below is to help you understand the fees and expenses that you, as a Common Shareholder, would bear directly or indirectly.

Example

The following example illustrates the expenses you would pay on a $1,000 investment in Common Shares assuming a 5% annual portfolio total return.*

* The example does not include sales load or estimated offering costs. The example should not be considered a representation of future expenses or rate of return and actual Fund expenses may be greater or less than those shown. The example assumes that (i) all dividends and other distributions are reinvested at NAV, and (ii) the percentage amounts listed under "Total annual expenses" above remain the same in the years shown. For more complete descriptions of certain of the Fund's costs and expenses, see "Management of the Fund - Advisory Agreements."
