Update: Invesco Funds Shareholder Votes Still Needed

Since completing its acquisition of Morgan Stanley Investment Management’s retail mutual fund business, including Van Kampen Investments, Invesco has sought shareholder approval of a number of agreements and plans of reorganization that, if approved, will result in a consolidated mutual fund line-up. Invesco believes this change will enhance their offering and better enable Invesco to deliver strong, consistent investment results over the long term.

At the shareholder meetings held on April 1^st and 14^th, sixty-five funds have received the votes necessary to proceed with their proposed reorganization. The following five funds had their shareholder meetings adjourned to May 11^th to allow time for continued voting.

Target Fund	Acquiring Fund
Invesco Value Fund	Invesco Van Kampen Comstock Fund
Invesco Dividend Growth Securities Fund	Invesco Diversified Dividend Fund
Invesco Technology Sector Fund	Invesco Technology Fund
Invesco Global Dividend Growth Securities Fund	Invesco Global Core Equity Fund
Invesco Global Advantage Fund	Invesco Global Growth Fund

Please encourage your clients who are shareholders in the above funds to vote in the current proxy campaign if they have not done so already.
