Annual Meetings for Five of Pioneer Investments' Closed-End Funds To Be Held on September 22, 2008

BOSTON--(Business Wire)--
Pioneer Investment Management, Inc. announced today that the
annual shareholder meetings for Pioneer Diversified High Income Trust
(AMEX: HNW), Pioneer Floating Rate Trust (NYSE: PHD), Pioneer High
Income Trust (NYSE: PHT), Pioneer Municipal High Income Trust (NYSE:
MHI), and Pioneer Municipal High Income Advantage Trust (NYSE: MAV)
will be held on September 22, 2008. With respect to each fund,
shareholders of record as of the close of business on July 9, 2008
will be entitled to vote at the meeting. The only matter to be acted
upon at each meeting is the election of trustees.

These funds are closed-end investment companies. Pioneer
Investment Management, Inc. is each fund's investment adviser.

Closed-end funds, unlike open-end funds, are not continuously
offered. There is a one-time public offering and once issued, 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.
