Footnote

1. Source: Morningstar. For each fund with at least a 3-year history, Morningstar calculates a risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of all sales charges), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receives a Morningstar Rating™ of 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 and rated separately.) A fund's overall rating is derived from a weighted average of the performance figures associated with its 3-, 5- and 10- year (if applicable ) rating metrics. Past performance does not guarantee future results. Morningstar Rating™ is for Class A shares only; other classes may have different performance characteristics. ©2006 Morningstar, Inc.
