Morningstar Ratings

Unless otherwise indicated, ratings shown below are Class A as of Apr 30, 2012

PAST PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS.

For each U.S domicile 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. The Overall Morningstar Rating™ for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metrics. Rating shown above is for Class A unless otherwise indicated and subject to change monthly. Other share classes may have different performance characteristics.
