The final determination of the tax attributes for dividends each year are made after the close of

the tax year. The final tax attributes for 2026 dividends are currently expected to include a

combination of ordinary taxable income and qualified dividends and may include capital gains

and return of capital.

The Fund maintains a dividend reinvestment plan (the “DRIP”) which provides for the

reinvestment of dividends on behalf of its registered stockholders who hold their shares with the

Fund’s transfer agent and registrar or certain brokerage firms that have elected to participate in

the DRIP. Under the DRIP, if the Fund declares a dividend, registered stockholders who have not

“opted out” of the DRIP at least ten days prior to the next dividend payment date will have their

dividend automatically reinvested into additional shares of the Fund’s common stock.
