BlackRock Announces Investment Policy Changes for Certain Insured Municipal Closed-End Funds

BlackRock Advisors, LLC today announced that the Board of Directors/Trustees of each of 20 of its insured closed-end funds (the “Funds”) have approved changes to certain investment policies of the Funds.

Historically, under normal market conditions, each Fund has been required to invest at least 80% of its assets in municipal bonds either (i) insured under an insurance policy purchased by the Fund or (ii) insured under an insurance policy obtained by the issuer of the municipal bond or any other party. In September 2008, the Funds adopted an amended investment policy of seeking to limit their purchase of municipal bonds to those bonds insured by insurance providers with claims-paying abilities rated investment grade or in the three highest ratings categories at time of investment (the “Insurance Policy”).

Following the onset of the credit and liquidity crises, the claims-paying ability rating of most of the municipal bond insurance providers has been lowered by the rating agencies. These downgrades have called into question the long-term viability of the municipal bond insurance market, which has the potential to severely limit the ability of BlackRock Advisors, LLC, the Fund's investment advisor ("BlackRock"), to manage the Funds under the Insurance Policy.

As a result, on September 2, 2010, BlackRock recommended, and the Boards approved, the removal of the Insurance Policy. As a result of this investment policy change, the Funds would not be required to dispose of assets currently held within the Funds. The Funds will maintain, and have no current intention to amend, their investment policy of, under normal market conditions, generally investing in municipal obligations rated investment grade or in the three highest ratings categories, as applicable.

As disclosed in its prospectus, each Fund is required to provide shareholders 60 days notice of a change to the Insured Policy. Accordingly, a notice describing the changes discussed above will be mailed to shareholders of record as of September 2, 2010. Following the prescribed 60-day notice period, BlackRock anticipates that it will gradually reposition the Funds’ portfolios over time, and that during such period, each Fund may continue to hold a substantial portion of its assets in insured municipal bonds. At this time, it is uncertain how long the repositioning may take, and the Funds may continue to be subject to risks associated with investing a substantial portion of their assets in preferred securities until the repositioning is complete. No action is required by shareholders of the Funds in connection with this change.

In connection with this change in non-fundamental policy, each of the Funds will undergo a name change to reflect its new portfolio characteristics. The new names of the Funds will be announced at or prior to the expiration of the 60-day notice period. Each Fund will continue to trade on New York Stock Exchange under its current ticker symbol.
