A large retirement services company is experimenting with a plan administration tool.

The retirement services arm of Great-West Life & Annuity Insurance Company, Greenwood Village, Colo., has decided to test the voluntary 401(k) plan rollover tool from RolloverSystems Inc., Charlotte, N.C., on some clients, RolloverSystems says.

Members of an employer-sponsored retirement plan can use the system to roll plan assets into individual retirement accounts over the telephone or through the Web.
