An assessment of a subaccount’s excess return over a risk-free rate (the return of the 90-day Treasury bill) after adjusting for all applicable fees, in comparison to similar subaccounts. In each Morningstar Category, the top 10% of subaccounts 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 subbacount. Subaccounts with less than three years of performance history are not rated.
