RiverSource Life Insurance Company Inc. has introduced a set of investment funds designed for variable annuity and variable universal life insurance customers.

The new Disciplined Asset Allocation Portfolios come with risk targets ranging from conservative to aggressive, according to RiverSource, a unit of Ameriprise Financial Inc., Minneapolis.

RiverSource money managers in Cambridge, Mass., will “re-optimize” the portfolios every month, RiverSource says.

RiverSource will not sell the portfolios with variable annuity contracts with living benefits, or with the company’s old single-premium variable life insurance policies, the company says.
