⁽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⁾

Total expenses 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.

⁽⁴⁾

Includes a reduction by the investment adviser of a portion of its adviser fee due to the Fund’s investment in the Morgan Stanley Institutional Liquidity Funds -Government Portfolio (equal to less than 0.005% of average daily net assets for the year ended October 31, 2025, 2024, 2023 and 2022).

⁽⁵⁾

Calculated by subtracting the Fund’s total liabilities (not including the borrowings payable/notes payable) from the Fund’s total assets, and dividing the result by the borrowings payable/notes payable balance in thousands.

⁽⁶⁾

Excludes the effect of custody fee credits, if any, of less than 0.005%. Effective September 1, 2015, custody fee credits, which were earned on cash deposit balances, were discontinued by the custodian.

⁽⁷⁾

Net investment income per share includes special dividends which amounted to $0.230 per share for the year ended October 31, 2016. Excluding special dividends, the ratio of net investment income to average daily net assets would have been 2.65% for the year ended October 31, 2016.
