Morningstar return is an assessment of the fund's excess return over a risk-free rate (the return of the 90-day Treasury bill) in comparison to similar funds, with an emphasis on downward variation. Therefore, if two funds have precisely the same return, the one with greater variations in its return is given the larger risk score. In each Morningstar Category, the top 10% of funds earn a High Morningstar Return, the next 22.5% Above Average, the middle 35% Average, the next 22.5% Below Average, and the bottom 10% Low. Morningstar Return is measured for up to three time periods (three-, five-, and 10-years). These separate measures are then weighted and averaged to produce an overall measure for the fund. Funds with less than three years of performance history are not rated.
