(1) Upon completion of twenty years of such service and upon retirement, each such member shall receive a pension which, together with an annuity, if any, which shall be the actuarial equivalent of his accumulated contributions at the time of his retirement and an additional pension which is the actuarial equivalent of the reserve-for-increased-take-home-pay to which he may then be entitled, if any, shall be sufficient to provide him with a retirement allowance equal to one-half of his final average salary.

(2) Upon attainment of age sixty-two and upon retirement without completion of twenty years of such service, each such member shall receive a pension which together with an annuity, if any, which shall be the actuarial equivalent of his accumulated contributions at the time of his retirement and an additional pension which is the actuarial equivalent of the reserve-for-increased-take-home-pay to which he may then be entitled, if any, shall be sufficient to provide him with a retirement allowance equal to one-fortieth of his final average salary for each year of creditable service in such fire department or police force or department. Every such member shall also be entitled to an additional pension equal to the pension for any creditable service rendered while not an employee of such fire department or police force or department as provided under paragraphs three and four of subdivision a of section three hundred seventy-five of this article. This latter pension shall not increase the total allowance to more than one-half of his final average salary. For the purpose only of determining the amount of the pension provided in this subdivision e, 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. f. The increased pensions to such members, as provided by this section, shall be paid from additional contributions made by the participating employer on account of such members. The actuary of the retirement system shall compute the additional contribution required for each member who elects to receive the special benefits provided under this section. Such additional contributions shall be computed on the basis of contributions during the prospective service of such member which will cover the liability of the retirement system for such extra pensions. Upon approval of the comptroller, such additional contributions shall be certified by him to the fiscal officer of the participating employer. The amount thereof shall be included in the annual appropriation of the participating employer for its fire department and police force or department. Such amount shall be paid on the warrant of the fiscal officer of the participating employer to the pension accumulation fund of the retirement system. g. In computing the twenty years of completed service of a member of a police department or fire department, full credit shall be given for military service as defined in subdivisions twenty-nine-a and thirty of section three hundred two of this chapter. In addition, full credit shall be given and full allowance shall be made for prior service in a fire department or police force or department, other than the force or department in which he is a member at the time of retirement, if his employer elects to assume the cost of such prior fire or police service as hereinafter provided. The member's employer, however, by appropriate action, may (a) in its initial action under this section, elect to assume all of the additional cost on account of service as an officer or member of any such department or force rendered to such employer prior to the effective date of such election and (b) in any subsequent action, as hereafter provided in this paragraph, elect to assume all of the additional cost on account of previous service as an officer or member of any such other department or force and, in addition may in its initial action under this section, elect to assume any multiple of twenty-five per centum of such additional cost on account of such service for such current employer rendered on and after the effective date of such initial election. Any subsequent election changing the percentage of additional cost assumed by an employer shall apply only to service rendered for such employer on and after the effective date of such subsequent election. The employer shall pay the additional cost so assumed by any such election by means of annual contributions which shall be determined by the actuary and paid by the employer in the same manner as the contributions required under section three hundred twenty-three of this article. An employer, which in its initial action elected to assume all of the additional cost on account of service only as an officer or member of its police or fire department rendered prior to the effective date of such election may elect to assume all of the additional cost, including the cost of the necessary actuarial reevaluation on account of previous service rendered as an officer or member of any such organized fire department or organized police force or department of any county, city, town, village, fire district, police district, or participating employer other than such employer. h. Upon retirement of any member pursuant to this section, any additional amounts credited to the member's annuity savings account pursuant to subdivision b of section three hundred thirty of this article shall be treated as excess contributions and shall be used to provide an annuity in addition to the annuity prescribed by this section. Any other amounts credited to the member's annuity savings account, except the amounts contributed or required to be contributed under this section and except such amounts as are required to produce the retirement allowance provided by subdivision e of this section, may at the option of the member at the time of retirement be withdrawn or used to provide an annuity in addition to the annuity prescribed by this section. i.
