A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.”

The amounts and sources of distributions reported in this Notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

The Fund has declared the May 2025 distribution pursuant to the Fund’s managed distribution plan (the “Plan”). Under the Plan, the Fund makes fixed monthly distributions in the amount of $0.0825 per share, which will continue to be paid monthly until further notice.
