All funds are closed-end investment companies. PHD, PHT, MHI and MAV trade on the New York Stock Exchange (NYSE). HNW trades on the NYSE MKT. Pioneer Investment Management, Inc. is each fund’s investment adviser.

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. Shareholders should not draw any conclusions about a fund’s investment performance based on a fund’s current distributions. 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.
