401k rpoduct/model

[Guest DU student]

I am writing a grad paper and i read about one of the bigger consulting firms (Milliman i believe) had a option where it tried to act as a db plan as far as the ending balance is guaranteed --i can't remember where i read it or who it was.

fro example, i want $1 million in 25 years. I have $90k begining balance and contribute X each yr, and they allow only a certain percentage invested in equities and i will have my $1 million at NRA.

can anyone point me to the actual description and or website of the firm offering it? I am not looking for any insurance or annuity products.

thanks in advance.
