Performance of a $10,000 Investment (as of September 30, 2025) This graph shows the change in value of a hypothetical investment of $10,000 in the Fund for the periods indicated. For comparison, the same investment is shown in the indicated index. Returns represent past performance. Total investment return at NAV is based on changes in the NAV of Fund shares and assumes reinvestment of dividends and distributions, if any, at market prices pursuant to the dividend reinvestment program sponsored by the Fund’s transfer agent. All return data at NAV includes fees charged to the Fund, which are listed in the Fund’s Statement of Operations under “Expenses.” Total investment return at market value is based on changes in the market price at which the Fund’s shares traded on the NYSE during the period and assumes reinvestment of dividends and distributions, if any, at market prices pursuant to the dividend reinvestment program sponsored by the Fund’s transfer agent. The Fund’s total investment return is based on the reported NAV as of the financial reporting period end date of September 30, 2025. Because the Fund’s shares trade in the stock market based on investor demand, the Fund may trade at a price higher or lower than its NAV. Therefore, returns are calculated based on both market price and NAV. Past performance is no guarantee of future results. The performance information provided does not reflect the deduction of taxes that a shareholder would pay on distributions received from the Fund or the sale of Fund shares. The current performance of the Fund may be lower or higher than the figures shown. The Fund’s yield, return, market price and NAV will fluctuate.
