Taxable-Equivalent Distribution Rate is computed using the maximum federal tax rate.

(a) At this time HNW believes that a portion of its distributions may include a return of capital in addition to net investment income and long-term capital gains. A return of capital is not a distribution of income or capital gains from the fund, does not necessarily reflect the fund's investment performance, and should not be considered "yield" or "income." Further information on the composition of the distribution will be made available on the payment date and will be available at pioneerinvestments.com. The final determination of tax characteristics of the fund’s distributions will occur after the end of the year, at which time it will be reported to shareholders.

The funds are closed-end investment companies. Three of these funds trade on the New York Stock Exchange (NYSE) under the following symbols: MHI, MAV, and PHD. HNW trades on the NYSE Amex. Pioneer Investment Management, Inc. is each fund’s investment adviser.

Keep in mind, dividends are not guaranteed. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and once issued, common shares of closed-end funds are bought and sold in the open market through a stock exchange and frequently trade at prices lower than their net asset value. Net Asset Value (NAV) is total assets less total liabilities divided by the number of common shares outstanding. For performance data on Pioneer's closed-end funds, please call 800-225-6292 or visit our closed-end pricing page.
