The Fund is managed through a duration-neutral, risk-controlled approach with a strong emphasis on the long-term perspective. The primary investment objective of the Fund is to seek current income that is substantially exempt from federal income tax. A secondary objective is to seek total return with relatively low volatility of principal. The Fund invests in municipal securities issued by governmental authorities throughout the United States and its territories. The Fund primarily purchases general obligation and pre-refunded bonds issued for any purpose as well as certain revenue bonds.
Performance data quoted represents past performance. Past performance does not guarantee future results. Investment return and principal value of an investment in the fund will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. The funds' current performance may be lower or higher than the performance data quoted.
Because the Fund may invest more than 25% of its total assets in municipal obligations issued by entities located in the same state or the interest on which is paid solely from revenues of similar projects, changes in economic, business or political conditions relating to a particular state or types of projects may have a disproportionate impact on the Fund. A bond's market value may be affected significantly by changes in interest rates – generally, when interest rates rise, the bond's market value declines and when interest rates decline, its market value rises ("interest rate risk").
