1. Computation of retirement allowance where member has elected to pay the entire additional cost: A member who has elected to contribute pursuant to this section and who has made the contributions required by this section shall be entitled to retire on or after his completion of twenty-five years of service as an officer or member of any such fire department, police force or police department, or upon the attainment of age sixty with less than twenty-five years of such service, by filing an application therefor in a manner similar to that provided in section three hundred seventy of this article. He thereupon shall receive, upon retirement, a retirement allowance which shall not exceed one-half of his final average salary. Such retirement allowance shall consist of:
(a) An annuity which shall be the actuarial equivalent of his accumulated contributions at the time of his retirement, and(b) A pension which is the actuarial equivalent of the reserve-for-increased-take-home-pay to which he may then be entitled, if any, and(c) A pension of one-one hundredth of his final average salary for each year of service as an officer or member of any such fire department, police force or police department, and(d) An additional pension of one-one hundred fortieth of his final average salary for each year of member service for which he otherwise shall be entitled to credit and which was earned by him since he last become a member, and(e) If he has had one or more years of service as a member, an additional pension which shall be equal to one-fiftieth of his final average salary for each year of prior service as an officer or member of any such fire department, police force or police department, plus one-seventieth of his final average salary for each year of prior service to which he otherwise shall be entitled to credit.(f) Upon completion of twenty-five years service, an additional pension, if required, of such amount as shall be necessary to increase the total amount of the benefits provided herein to one-half of his final average salary. The pension provided by this sub-paragraph shall be payable only if a member retires from service on or before the last day of the calendar month next succeeding the calendar month in which he attains age sixty-two. Provided, however, that in the case of any member who attained the age of sixty-two on or before July first, nineteen hundred sixty-six, to be eligible for additional pension credit under this sub-paragraph, his service shall be terminated and he shall retire on or before December thirty-first, nineteen hundred sixty-seven. For the purpose only of determining the amount of the pension provided in this paragraph, the annuity shall be computed as it would be if it were not reduced by the actuarial equivalent of any outstanding loan, and if it were not increased by the actuarial equivalent of any additional contributions, and if it were not reduced by reason of the member's election to decrease his annuity contributions to the retirement system in order to apply the amount of such reduction in payment of his contributions for old-age and survivors insurance coverage.2. Computation of retirement allowance where employer has elected to pay all or part of the additional cost: A member who has elected to contribute pursuant to this section and who has made the contributions required by this section, and whose employer has by appropriate action elected to pay all or part of the additional cost of the benefits provided by this section, shall be entitled to retire on or after his completion of twenty-five years of service as an officer or member of any such fire department, police force or police department, or upon the attainment of age sixty with less than twenty-five years of such service, by filing an application therefor in a manner similar to that provided in section three hundred seventy of this article. He thereupon shall receive, upon retirement, a retirement allowance which shall not exceed one-half of his final average salary. Such retirement allowance shall consist of:
(a) An annuity which shall be the actuarial equivalent of his accumulated contributions at the time of his retirement, and(b) A pension which the actuarial equivalent of the reserve-for-increased-take-home-pay to which he may then be entitled, if any, and(c) A pension for each year of service as an officer or member of any such fire department, police force or police department, rendered on and after the effective date of the employer's election under this section, computed pursuant to the one of the following four formulae which is appropriate: (1) If his employer elected to pay twenty-five per centum of the additional cost on account of such service rendered on and after the effective date of such election, such pension shall be six-seven hundredths (6/700) of his final average salary for each year of such service after such date, or(2) If his employer elected to pay fifty per centum of the additional cost on account of such service rendered on and after the effective date of such election, such pension shall be one-one hundredth (1/100) of his final average salary for each year of such service after such date, or(3) If his employer elected to pay seventy-five per centum of the additional cost on account of such service rendered on and after the effective date of such election, such pension shall be eight-seven hundredths (8/700) of his final average salary for each year of such service after such date, or(4) If his employer elected to pay one hundred per centum of the additional cost on account of such service rendered on and after the effective date of such election, such pension shall be nine-seven hundredths (9/700) of his final average salary for each year of such service after such date, and(d) An additional pension for such service, exclusive of prior service, rendered before the effective date of the employer's initial election under this section, of one-fiftieth of his final average salary for each year of such service, minus a sum equal to the annuity provided out of the normal contributions, with accumulated interest thereon, made by the member during such period and minus a sum which is the actuarial equivalent of the reduction in his contributions pursuant to the provisions of section three hundred seventy-a of this article, if any, during such period, with regular interest thereon, and(e) An additional pension of one-one hundred fortieth of his final average salary for each year of member service for which he otherwise shall be entitled to credit and which was earned by him since he last became a member, and(f) If he has had one or more years of service as a member, an additional pension which shall be equal to one-fiftieth of his final average salary for each year of such service, which is credited as prior service, plus one-seventieth of his final average salary for each year of prior service for which he otherwise shall be entitled to credit.(g) Upon completion of twenty-five years service, an additional pension, if required, of such amount as shall be necessary to increase the total amount of the benefits provided herein to one-half of his final average salary. The pension provided by this sub-paragraph shall be payable only if a member retires from service on or before the last day of the calendar month next succeeding the calendar month in which he attains age sixty-two. Provided, however, that in the case of any member who attained the age of sixty-two before or within one month after his employer first elected to assume all or part of the additional cost of service as provided by paragraph two of subdivision d of this section, to be eligible for additional pension credit under this sub-paragraph, his service shall be terminated and he shall retire within three months after his employer so elects or on or before December thirty-first, nineteen hundred sixty-eight, whichever shall last occur. For the purpose only of determining the amount of the pension provided in this paragraph, the annuity shall be computed as it would be if it were not reduced by the actuarial equivalent of any outstanding loan, and if it were not increased by the actuarial equivalent of any additional contributions, and if it were not reduced by reason of the member's election to decrease his annuity contributions to the retirement system in order to apply the amount of said reduction in payment of his contributions for old-age and survivors insurance coverage.
