Los Angeles City Deferred Compensation Plan rehired Mercer as investment consultant, said Steven Montagna, executive director, in an email.
The $9 billion 457 plan's board issued an RFP in April because Mercer's contract was due to expire on Dec. 31.
The board approved rehiring Mercer at its Dec. 21 meeting, Mr. Montagna said.
Callan and RVK were the other finalists.
