Associated Press, New York, hired Vanguard to replace ADP Retirement Services as record keeper for its $100 million 401(k) plan and will now move to daily valuation, said Jessica Bruce, benefits administrator. Vanguard also will administer the plan, which had been administered internally. Fee issues brought about the change, Ms. Bruce said. ADP officials did not return phone calls by press time. AP also has a $203 million defined benefit plan.
