Where to find additional information

Each fund listed above as an Acquiring Fund will file with the Securities and Exchange Commission (the SEC) definitive proxy materials that will include a prospectus for the Acquiring Fund and a proxy statement for each applicable Target Fund. All shareholders are advised to read the definitive proxy statements in their entirety when they become available because they will contain important information regarding the funds, the board’s considerations in recommending the reorganizations, the identity of the participants in the solicitation, and a description of any interest of those persons in the transactions and related matters.

Definitive proxy statements are expected to be mailed to fund shareholders during the first half of 2013. Shareholders may obtain a free copy of the definitive proxy statements when available, along with other documents filed by the funds with the SEC, at the SEC’s website at http://www.sec.gov. In addition, copies of the definitive proxy statements, once available, may be obtained, free of charge, by directing a request to Invesco via mail to 11 Greenway Plaza, Suite 1000, Houston, TX 77046 or via phone to 800 959 4246.

Each fund also files annual and semiannual reports and other information with the SEC. You may read and copy any reports, statements, or other information filed by a fund at the SEC’s public reference room at 100 F Street, N.E., Washington, D.C., 20549. Please call the SEC at 1 800 SEC 0330 for further information on the public reference room. Filings made with the SEC by a fund are also available to the public from commercial document-retrieval services and at the website maintained by the SEC at http://www.sec.gov.

The foregoing is not an offer for sale of any security or a solicitation of any proxy.
