NU Online News Service, March 20, 2003, 4:44 p.m. EST – Only 18% of the biggest private U.S. employers put a single firm in charge of actuarial services and administration services for their defined-benefit pension plans, according to a study by Watson Wyatt & Company Holdings Inc., Washington.

Twenty-two percent of the biggest companies hire separate companies to handle administration and actuarial services, and 44% handle some pension services in-house, Watson Wyatt says.

Sixteen percent of the biggest companies do not have to worry about defined-benefit plan administration because they have limited themselves to offering defined-contribution plans.
