		Press Release For immediate release
		Invesco Closed-End Funds Announce Approval of Plan to Redeem Auction Rate Preferred Shares at Par and Approval of Fund Redomestications and Mergers
		CONTACT: Ivy McLemore 713-214-1904 ivy.mclemore@invesco.com

HOUSTON, November 30, 2011 — Invesco Advisers, Inc. today announced that the Boards of Trustees (the “Redeeming Funds’ Board”) of the Invesco tax-exempt closed-end funds (the “Redeeming Funds”) have approved a plan to redeem all of the Redeeming Funds’ outstanding auction rate preferred shares (“ARPS”) at their respective liquidation preferences (sometimes referred to as “at par”), together with accrued and unpaid dividends, if any, to the redemption date. These redemptions, which will total approximately $583,750,000 (excluding dividends), are anticipated to be funded with proceeds received from the issuance of Variable Rate Munifund Term Preferred Shares (“VMTPS”) and Tender Option Bonds (“TOBs”). VMTPS are a variable rate form of preferred stock with a mandatory redemption date.

Invesco is currently in active negotiations with various banks regarding the prospective issuance of VMTPS and TOBs. The timing of each Redeeming Fund’s replacement of ARPS with VMTPS and TOBs may vary and is subject to a number of factors, including, but not limited to, the negotiation of definitive agreements, changes in interest rates and other market conditions, the willingness of buyers to purchase VMTPS and TOBs, the eligibility of collateral held by the Redeeming Funds and the availability of attractive credit ratings, any of which may delay or prevent redemption of a Redeeming Fund’s ARPS. Invesco and the Redeeming Funds’ Board currently are targeting the redemptions to occur in the first half of 2012. However, definitive agreements regarding these transactions have not yet been entered into and there can be no assurance that all or any portion of any Redeeming Fund’s ARPS will be redeemed. Accordingly, the Redeeming Funds’ Board will determine, based on the facts and circumstances applicable to each Redeeming Fund at any particular time, when redemption of each Redeeming Fund’s ARPS will occur.

Invesco will keep market participants and shareholders informed of material developments in the Redeeming Funds’ progress to redeem ARPS via press releases and on Invesco’s website at www.invesco.com/portal/site/us/news.

The Boards also considered the impact of the mergers on the fee levels of the funds and approved adjustments to certain funds’ contractual fee levels, subject to shareholder approval, to further rationalize fees across the Invesco complex and against competitors’ fee levels. Shareholder meeting dates, voting information and other details regarding the proposed fund redomestications and mergers will be included in subsequent communications and on Invesco’s website at www.invesco.com/portal/site/us/news.

The proposed redomestications and mergers remain subject to certain conditions, including approval by shareholders of the funds and customary closing conditions. Each fund participating in a redomestication or a merger will file a definitive proxy statement with the Securities and Exchange Commission (the “SEC”). These proxy statements will also include prospectuses for the funds listed above as surviving funds. 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 redomestications and the mergers, 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 2012. 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 2500, Houston, TX 77046 or via phone to 800 959 4246.

Each fund also files annual and semi-annual 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 securities nor a solicitation of any proxy.
