(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) Interest and fee expense relates to the liability for floating rate notes issued in conjunction with residual interest bond transactions. (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 94.5% of the per share liquidation preference. Absent this transaction, the total return based on net asset value would have been 2.93%. (5) Ratios do not reflect the effect of dividend payments to APS shareholders, if any. (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 liability for floating rate notes issued in conjunction with residual interest bond transactions and/or iMTP shares issued to redeem a portion of the Trust’s APS. (8) As of November 30, 2018, the Trust had no APS and iMTP shares outstanding. (9) Preferred shares represent iMTP shares and APS as of November 30, 2017 and 2016 and APS as of November 30, 2015. (10) Calculated by subtracting the Trust’s total liabilities (not including the preferred shares) from the Trust’s total assets, and dividing the result by the number of preferred shares outstanding. (11) Plus accumulated and unpaid dividends. † Ratios based on net assets applicable to common shares plus preferred shares (iMTP and APS, as applicable) are presented below. Ratios do not reflect the effect of dividend payments to APS shareholders and exclude the effect of custody fee credits, if any.
