Richard Riordan, Los Angeles' millionaire former mayor, plunged deeper into the fray over public pensions Friday, announcing he is finalizing language for a ballot initiative that would move newly hired workers into 401(k)-style plans and freeze retirement benefits for existing workers.
Riordan and his advisers said the proposal would save hundreds of millions of dollars a year by 2017, in part by phasing out government pensions as new employees come into the city workforce.
