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.
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.
