Computation of normal retirement allowances; return of accumulated contributions

The monthly amount of the retirement allowance for any member of MERS Plan A Tier 2 shall consist of an amount equal to three percent of the member's final compensation multiplied by his years of creditable service. In addition: (1) Any city marshal or deputy city marshal shall receive an additional regular retirement benefit computed as follows: the monthly average of the seventy-two highest consecutive or joined months of supplemental marshals' earnings on which contributions were paid to the retirement system multiplied by the number of years contributions were paid to the retirement system on supplemental marshals' earnings multiplied by three percent for all service as a city marshal or deputy city marshal. Should the period for which contributions are paid to the retirement system for supplemental marshals' earnings be less than seventy-two months, then the actual period on which contributions were paid shall be used to determine average supplemental marshals' earnings used to compute this benefit. (2) Should a retired member die without having received in retirement benefits an amount equal to his accumulated contributions standing to his credit at the date of his retirement, and leave no eligible survivors, any balance remaining to his credit shall be paid to his designated beneficiary or, if none, his estate.
