1 Class A shares incepted on 4-11-05. Performance shown prior to the inception of Class A reflects the performance of the Investor Class shares adjusted to reflect Class A sales charges and expenses, as applicable.
2 Please note, Morningstar provides an extended performance rating for some mutual funds in its universe. Share classes that don’t have a 1, 3-, 5-, or 10-year performance history may receive a hypothetical Morningstar Rating based on the oldest surviving share class of the fund. Morningstar computes the funds’ new return stream by appending an adjusted return history of the oldest share class and the extended performance rating is determined by comparing the adjusted-historical returns to the current open-end mutual fund universe. For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees, unless otherwise indicated), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive five stars, the next 22.5% receive four stars, the next 35% receive three stars, the next 22.5% receive two stars, and the bottom 10% receive one star. (Each share class is counted as a fraction of one fund within this scale and is rated separately, which may cause slight variations in the distribution percentages.) Past performance is no guarantee of future results.
3 The Lipper General & Insured Municipal Debt Funds Average is an average of funds that invest at least 65% of their assets in municipal debt issues in the top four credit ratings. The total return of the Lipper Average does not include the effect of sales charges. You cannot invest directly in a Lipper Average.
4 The Barclays Municipal Bond Index is an unmanaged index composed of long-term tax-exempt bonds with a minimum credit rating of Baa. You cannot invest directly in an index.
5 The daily factor is the interest factor that generates the dividend on a daily basis.
6 The 7-day current yield is an annualized net yield that describes the annualized income earned over a 7-day period. The 30-day current yield is an annualized net yield that describes the annualized income earned over a 30-day period. The current yield calculations assume that the income earned on the principal is not reinvested in the fund. The 7-day effective yield is annualized net yield that describes the amount one is expected to earn over a 1-year period assuming that dividends are reinvested at the average rate of the last 7-days. The 30-day effective yield is an annualized yield that describes the amount that would be earned over a 1-year period if dividends were reinvested at the average rate of the last 30 days.
7 The 7-day current unsubsidized yield does not reflect the effect of any fee or expense waivers made by the Fund's manager.
8 The 30-day SEC yield is calculated with a standardized formula mandated by the SEC. The formula is based on maximum offering price per share and includes the effect of any fee waivers. Without waivers, yields would be reduced. The 30-day unsubsidized SEC yield does not reflect waivers in effect. A fund's actual distribution rate will differ from the SEC yield and any income distributions from the fund may be higher or lower than the SEC yield.
