| 1 | Market Yield is based on the Fund’s current annualized monthly dividend divided by the Fund’s current market                                                                                                                                         
 price as of the end of the reporting period. Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis. It is                                    
 based on a federal income tax rate of 40.8%. Your actual federal income tax rate may differ from the assumed rate. The Taxable-Equivalent Yield also takes into account the percentage of the Fund’s income generated and paid by the Fund (based on 
 payments made during the previous calendar year) that was not exempt from federal income tax. Separately, if the comparison were instead to investments that generate qualified dividend income, which is taxable at a rate lower than an            
 individual’s ordinary graduated tax rate, the fund’s Taxable-Equivalent Yield would be lower.                                                                                                                                                        |

Each Fund’s distribution policy, which may be changed by the Board, is to make regular monthly cash distributions to holders of its common shares (stated in terms of a fixed cents per common share dividend distribution rate which may be set from time to time). The Fund intends to distribute all or substantially all of its net investment income each year through its regular monthly distribution and to distribute realized capital gains at least annually. In addition, in any monthly period, to maintain its declared per common share distribution amount, the Fund may distribute more or less than its net investment income during the period. In the event the Fund distributes more than its net investment income during any yearly period, such distributions may also include realized gains and/or a return of capital. To the extent that a distribution includes a return of capital the NAV per share may erode. If the Fund’s distribution includes anything other than net investment income, the Fund will provide a notice to shareholders of its best estimate of the distribution sources at that the time of the distribution. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’ 1099-DIVforms after the end of the year.
