board of trustees shall adopt and regular interest, the actuary of the
retirement system shall determine for each member the proportion of
earnable compensation which, when deducted from each payment of
his prospective compensation earnable prior to his attainment of age
sixty and accumulated at regular interest until his attainment of
such age, shall be computed to provide at that time an annuity equal
to one one-hundred-twentieth of average final compensation for each
year of service as a member at age sixty, and commencing as of July

compensation shall be computed to remain constant. Each member
who has a Group 1, Group 2 or Group 3 member on December 31,

earnable compensation during his last ten years of continuous, honor-
able and faithful service, multiplied by the number of years of service
after December 31, 1960.

to the contributions deducted from compensation as hereinbefore
provided, any member may redeposit in the annuity savings fund by
