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.) 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. The Thompson Plumb Bond Fund was rated against the following numbers of U.S.-domiciled Short-term Bond funds over the following time periods: 384 funds in the last three years, 318 funds in the last five years, and 168 funds in the last ten years for the period ending 12/31/2009.
