The Morningstar Rating™ for funds, or "star rating", is calculated for managed products with at least a 3-year history. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance (not including the effects of sales charges, loads and redemption fees if applicable), placing more emphasis on downward variations and rewarding consistent performance. Managed products; including open-end mutual funds, closed-end funds and exchange-traded funds; are considered a single population for comparative purposes. 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. © Morningstar, Inc.

LIPPER CLASSIFICATION Intermediate Municipal Debt Funds

Lipper Category returns and rankings are calculated by Lipper Inc., a Reuters Company, which is a nationally recognized organization that compares the performance of mutual funds with similar investment objectives. The Category returns represent the average performance of included funds, while rankings compare an individual fund's returns to those of the other funds in its category. Both are based on total return performance, with capital gains and dividends reinvested, with annual operating expenses deducted, but without including front or back-end sales charges. Rankings begin with the actual share class inception. Rankings are relative to a peer group and do not necessarily mean that the fund had high total returns. Rankings do not reflect sales loads
