The fund will invest primarily in investment grade short-term municipal securities. The issuers of these securities may be located in any U.S. state, territory or possession. The fund may also invest a portion of its net assets in certain taxable debt instruments. The fund expects that it will normally maintain an effective maturity of 3 years or less. In selecting investments for purchase and sale, the subadviser tries to manage risk as much as possible. Based on the subadvisers analysis of municipalities, credit risk, market trends and investment cycles, the subadviser attempts to invest more of the funds assets in undervalued municipal securities and less in overvalued municipal securities taking into consideration maturity, sector, credit, state and supply and demand levels. The subadviser also attempts to identify and invest in municipal issuers with improving credit and avoid those with deteriorating credit. The fund invests in securities rated investment grade by at least one nationally recognized statistical rating organization or unrated securities that the subadviser believes are of comparable quality. The subadviser may retain securities if the rating of the security falls below investment grade and the subadviser deems retention of the security to be in the best interests of the fund. In addition, to implement its investment strategy, the fund may buy or sell derivative instruments (such as treasury futures) to use as part of a strategy designed to reduce exposure to other risks, such as interest rate or credit risks.
