Municipal Bond Fund

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").

Bloomberg Municipal Bond Index is a broad market performance benchmark for the tax-exempt bond market, the bonds included in this index must have a minimum credit rating of at least Baa.

Time periods greater than one year are annualized.

The Morningstar Rating™ for funds, or "star rating", is calculated for managed products with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The Morningstar Rating does not include any adjustment for sales loads. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its 3-, 5-, and 10-year (if applicable) Morningstar Rating metrics. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent 3-year period actually has the greatest impact because it is included in all three rating periods.
