(2) If for any month the waiver does not apply to the full retirement allowance due under this chapter, the waiver applies first to all or the necessary portion of prior service pension, then to all or to the necessary portion of current service pension, and then to the necessary portion of annuity.
(3) The waiver may be revoked at any time, but no retirement allowance or other benefit waived for the period of time in which the waiver is in effect shall be paid. The revocation shall be made in writing and filed with the board. If a person dies during the period of time in which the waiver is in effect, the waiver is considered revoked on the date of such death. [Formerly 237.157; 2003 c.733 §54; 2005 c.22 §177]
