⁽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 Trust’s dividend reinvestment plan.

⁽³⁾ The total return based on net asset value reflects the impact of the tender and repurchase by the Trust of a portion of its APS at 92% of the per share liquidation preference. Absent this transaction, the total return based on net asset value would have been 6.94%.

⁽⁴⁾ The total return based on net asset value reflects the impact of the tender and repurchase by the Trust of a portion of its APS at 95% of the per share liquidation preference. Absent this transaction, the total return based on net asset value would have been 10.95%.

⁽⁵⁾ Ratios do not reflect the effect of dividend payments to preferred shareholders.

⁽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⁾ Interest and fee expense relates to the notes payable incurred to partially redeem the Trust’s APS.

⁽⁸⁾ Includes a reduction by the investment adviser of a portion of its adviser fee due to the Trust’s investment in the Morgan Stanley Institutional Liquidity Funds – Government Portfolio (equal to less than 0.005% of average daily net assets for the years ended October 31, 2023 and 2022).

⁽⁹⁾ Calculated by subtracting the Trust’s total liabilities (not including the notes payable and preferred shares) from the Trust’s total assets, and dividing the result by the notes payable balance in thousands.

⁽¹⁰⁾ Calculated by subtracting the Trust’s total liabilities (not including the notes payable and preferred shares) from the Trust’s total assets, dividing the result by the sum of the value of the notes payable and liquidation value of preferred shares, and multiplying the result by the liquidation value of one preferred share. Such amount equates to 301%, 272%, 306%, 266%, 282%, 290%, 290%, 286%, 256% and 265% at October 31, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015 and 2014, respectively.

⁽¹¹⁾ Plus accumulated and unpaid dividends.
