⁽¹⁾ Computed using average shares outstanding.

⁽²⁾ Returns are historical and are calculated by determining the percentage change in net asset value or market value with all distributions reinvested. Distributions are assumed to be reinvested at prices obtained under the Fund’s dividend reinvestment plan.

⁽³⁾ Includes a reduction by the investment adviser of a portion of its adviser fee due to the Fund’s investment in the Liquidity Fund (equal to less than 0.005% of average daily net assets for the years ended September 30, 2024, 2023 and 2022).

⁽⁴⁾ Amount is less than $0.0005.

⁽⁵⁾ Total returns do not reflect amounts reimbursed and/or waived by the adviser and certain of its affiliates, if applicable. Net expenses are net of all reductions and represent the net expenses paid by the Fund.
