- Van Kampen Trust for Insured Municipals (NYSE: VIM) (the "Trust") has adopted a change in its policy regarding the credit rating on insurers of municipal securities in which the Trust invests. The Trust's investment objective is to provide investors with a high level of current income exempt from federal income tax, consistent with preservation of capital. The Trust seeks

to achieve its investment objective by investing primarily in insured municipal securities. The Trust is not changing its investment objective or its investment policy of investing in insured municipal securities.

In connection with the unusual recent instability in the marketplace, many of the insurers of municipal securities have experienced ratings downgrades by the ratings agencies that rate such insurers' claims paying ability. This affects many mutual funds that invest in insured municipal securities because many such funds (including the Trust) currently have policies that require such funds to invest substantially all of their assets in municipal securities that are insured at the time of investment by an insurer whose claims paying ability is rated AAA. As a result of the recent downgrades, the Board of Trustees of the Trust has approved a policy change for the Trust to require the Trust to invest at least 80% of its net assets in municipal securities that are insured at the time of purchase by insurers whose claims paying ability is rated A or better by at least one nationally recognized statistical rating organization. The changed policy reflects the current state of the marketplace and reflects that the claims-paying ability of many current insurers may not be upgraded again to AAA in the near future.

Management of the Trust believes that the changed policy allows the Trust to continue to purchase higher quality insured municipal securities, while acknowledging the market price impact and moderately increased credit risk related to these downgrades among insurers. While the market risk and the credit risk of the Trust investing in insured municipal securities generally should be lower than the risks of a fund investing in similar municipal securities that are uninsured, insurance does not eliminate the market risk or credit risk of the securities in the Trust's portfolio. A downgrade of an insurer would generally subject the Trust to potential market value declines and increased credit risk on the municipal securities insured by such insurer.
