Dorset County Council, Dorchester, England, is searching for an actuary for its L817 million ($1.26 billion) pension scheme, said Nick Bucklin, council investment manager.
Incumbent Watson Wyatt Worldwide was asked to rebid, he said.
"We decided it was about time we reviewed our arrangements; Watson Wyatt has been with us for a long time, and we thought it's best practice to go to re-tender," he said.
