The closing market price and NAV are based on data as of May 2, 2016. The Market Price Distribution Rate is calculated by dividing the latest declared monthly distribution per share (annualized) by the market price. The NAV Distribution Rate is calculated by dividing the latest declared monthly distribution per share (annualized) by the NAV per share.

*PHT’s May distribution of $0.0850 per share represents a $0.0100 per share decrease from the previous monthly distribution of $0.0950 per share. The lower distribution rate is due to several factors, including but not limited to, certain fiscal year-end tax adjustments, the impact of foreign exchange, the impact of deleveraging related to the decline in the high yield sector in the first quarter of 2016 and the continued replacement of portfolio securities that are called or mature with instruments having lower yields. This distribution change was made to better align the fund’s distribution rate to its current and projected level of earnings.

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.
