Such member's rate of contribution pursuant to this section shall be appropriately reduced pursuant to section seventy-a of this article for such period of time as his employer contributes pursuant to such section toward pensions-providing-for-increased-take-home-pay provided, however, that such member may by written notice duly acknowledged and filed with the comptroller, make an election to waive such reduction as provided by subdivision j of section twenty-one of this article. One year or more after the filing thereof, a member may withdraw any such election by written notice duly acknowledged and filed with the comptroller.
Only for the purpose of determining the amount of the pension provided in this subdivision, 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 or contributions pursuant to waiver under subdivision j of section twenty-one of this article, and if it were not reduced by reason of the members 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.
