AIM Investments announced today that the Boards of Trustees of the applicable funds have approved the following name changes, effective Feb. 28, 2007: AIM International Bond Fund to AIM International Total Return Fund AIM Enhanced Short Bond Fund to AIM LIBOR Alpha Fund Both name changes better reflect the funds� investment focus of outperforming their benchmarks � the Lehman Brothers Global Aggregate ex-U.S. Index (unhedged) for the AIM International Bond Fund and the three-month U.S. dollar LIBOR for the AIM Enhanced Short Bond Fund � through an analysis of a variety of alpha sources (specific factors affecting the return on investments relative to the benchmark), including, among others, high-yield and emerging-market risk, country risk and currency risk. Important Information about Investing in AIM International Bond Fund and AIM Enhanced Short Bond Fund Foreign securities have additional risks, including exchange rate changes, political and economic developments, the relative lack of information about these companies and the potential lack of strict financial and accounting controls and standards. The funds may use enhanced investment techniques such as leverage and derivatives. Leveraging entails special risks such as magnifying changes in the value of the portfolio�s securities. Derivatives are subject to counterparty risk � the risk that the other party will not complete the transaction with the fund. The prices of securities in the funds may decline in response to market risks, changes in interest rates, effective maturities and credit ratings of those securities. The funds may invest in asset-backed or mortgage-backed securities which may lose value if they are called or prepaid. Investing in higher-yielding, lower-rated corporate bonds (commonly known as �junk bonds�) has a greater risk of price fluctuation and loss of principal and income than government securities, such as Treasury bills, notes and bonds. Treasuries are guaranteed by the government for repayment of principal and interest if held to maturity. Fund shares are not insured, and their value and yield will vary with market conditions. Investors should carefully assess the risk associated with investing in these funds. The funds may buy or sell currencies other than the U.S. dollar and use derivatives involving foreign currencies in order to capitalize on anticipated changes in exchange rates.
