The inception date of the Class A and Class C shares was 3-31-08. Performance shown for Class C shares prior to its inception reflects the performance of the Investor Class shares, adjusted to reflect the higher expenses applicable to Class C shares. Performance shown for Class A shares prior to its inception reflects the performance of the Investor Class shares and includes the higher expenses applicable to the Investor Class shares. If these expenses had not been included, returns would be higher.

Please note, Morningstar provides an extended performance rating for some mutual funds in its universe. Share classes that don't have a one-, three-, five-, or 10-year performance history may receive a hypothetical Morningstar Rating based on the oldest surviving share class of the fund. Morningstar computes the fund's 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 with 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), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each 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. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) Past performance is no guarantee of future results.
