Deferred retirement means you are leaving your contributions and
  interest on deposit with MercedCERA until you begin receiving a
  pension in the future. This option is only available if you are
  fully vested with at least five years of retirement service
  credit or reach age 70.
  As a deferred member, you may receive your retirement allowance
  any time that you are eligible to retire. In order to apply for
  retirement, contact the MercedCERA office when you are eligible
  or want to receive benefits. 
  Deferred members may cancel their deferred retirement and
  withdraw any accumulated contributions prior to receiving a
  retirement allowance, unless you have established reciprocity
  with an eligible public agency.
