1. Present employee and future entrant with 20 or more years of service-age and service annuity provided from the total sum accumulated to his credit from employee contributions and city contributions for such annuity, and, in addition in the case of a present employee, prior service annuity from the total sum accumulated to his credit for such annuity.

2. Present employee and future entrant with 10 or more but less than 20 years of service-age and service annuity provided from the total sum accumulated to his credit for such annuities from employee contributions plus 1/10 of the city contributions for each year of service after the first 10 years and in addition, in the case of a present employee, 1/10 of the total sum accumulated to his credit for prior service annuity under “The 1935 Act”  1 and this Article, for each year of service after the first 10 years.

Any such annuity shall be computed as though the employee were age 55 when granted regardless of his actual age at the time of application for annuity. An employee shall not be entitled to annuity for any period between the date he attained age 55 and the date of application for annuity.
