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, fee waivers, 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. For funds with loads, the Morningstar rating on a load-waived basis is provided, when available. Load-waived ratings do not include any front- or back-end sales loads and are intended for investors that have access to such purchase terms. Funds with loads are waived for plans administered by ICMA-RC. Past performance is no guarantee of future results.
