The investment seeks to achieve as high a total return over time as is considered consistent with prudent investment risk, preservation of capital and recognition of the fund's current asset allocation.
The fund is a "fund of funds". It allocates its assets among underlying funds according to an asset allocation strategy that becomes increasingly conservative until it reaches approximately 50% in equity and similar funds and 50% in fixed income funds, including money market funds, in 2055, and approximately 35% in equity and similar funds and 65% in fixed income funds, including money market funds, approximately fifteen years after that (2070).
