Notes

Investors should not necessarily draw any conclusions about the funds’ investment performance from the amount of these distributions.

Each fund estimates that a portion of its distribution does not represent income or realized capital gains. Therefore, such portion of its distribution may be a return of capital. A return of capital may occur when some or all of the money invested in the fund is returned to the investor. A return of capital distribution does not necessarily reflect the fund’s investment performance and should not be considered “yield” or “income.”

The amounts and sources of distributions reported under the notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon each fund’s investment experience during the remainder of its respective fiscal year and may be subject to change based on tax regulations. Each fund will provide investors with a Form(s) 1099 for the calendar year that explains how to report these distributions for federal income tax purposes.

The funds are closed-end investment companies. Four of these funds trade on the New York Stock Exchange (NYSE) under the following symbols: MHI, MAV, PHT, and MIO; HNW trades on the NYSEAMER.

Keep in mind, distribution rates are not guaranteed. A fund’s distribution rate may be affected by numerous factors, including changes in actual or projected investment income, the level of undistributed net investment income, if any, and other factors. Closed-end funds, unlike open-end funds, are not continuously offered. 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.
