(b) by multiplying such amount computed pursuant to subitem (a) of this item (ii) by a fraction, the numerator of which is the number of years of service for which he or she is credited with respect to such entire period, and the denominator of which is the number of years of service for which he or she would be credited with respect to such entire period if no such sub-periods were included therein.

(7) Upon the filing of a new selection of mode of benefit pursuant to this item (B) by any such person entitled to a recomputation, such new selection shall be irrevocable and such person shall not be entitled to file any other selection of mode of benefit with respect to such retirement allowance (or any component thereof) which became payable to him or her prior to the termination date of eligibility for option re-selection.
(8) No new selection of mode of benefit filed pursuant to the preceding sub-items of this item (B) shall be valid or effective as a change of mode of benefit or for any other purpose unless the person entitled to a recomputation of benefits who files such new selection is alive on the date (hereinafter referred to as the "validating date") three hundred sixty-five days after the date of filing of such new selection of mode of benefit. If such person filing such new selection of mode of benefit is alive on the validating date with respect to such new selection, such new selection shall become valid and effective on such validating date; provided, however, that from and after the effective date of retirement of such person making such valid and effective new selection of mode of benefit (if he or she retired for service or superannuation or for ordinary or accident disability) or from and after the date on which payability of the original benefits of such person began (if he or she was a discontinued member or Tier III member entitled to a vested benefit or Tier IV member entitled to a vested benefit), such new selection of mode of benefit shall supersede such original selection of mode of benefit and shall apply to and govern the amount of benefits payable to such person or to his or her designated beneficiary or estate.
(C) Nothing contained in item (A) or item (B) of this subparagraph (vi) shall be construed as preventing any change in selection of mode of benefit where such change is authorized by section 13-565 of the code.

(viii) Notwithstanding the provisions of subparagraph (i) of this paragraph (g) prescribing a rate of regular interest of seven per centum per annum, compounded annually, for specified members described in such subparagraph (i), the rate of regular interest which shall be applied to fix the rate of interest on any loan to any such member eligible to borrow shall be four per centum per annum, compounded annually.

(c) Solely for the purpose of use as the minuend from which the payments of such pension component to such member are subtracted in order to determine the amount of the Option 1 benefit payable, upon such member's death, to such member's beneficiary or estate by reason of such Option 1 selection in relation to such pension component, the present value of such member's maximum pension, as it was at the time of such member's retirement, shall be deemed to be the greatest of:
(i) such present value determined on the basis of gender-neutral mortality tables and an interest assumption consisting of regular interest of seven per centum per annum, compounded annually; or
(ii) such present value determined on the basis of the female mortality tables and the regular interest applicable to such member in effect immediately prior to the date of enactment (as certified pursuant to section forty-one of the legislative law) of this subdivision fifty-nine; or
(iii) such present value determined on the basis of the male mortality tables and the regular interest applicable to such member in effect immediately prior to the date of enactment of this subdivision.
(d) The pension component payable to such member shall be computed on the basis of gender-neutral mortality tables and an interest assumption consisting of regular interest of seven per centum per annum, compounded annually, so that:
(i) the present value, as it was at the time of such member's retirement, of such component; plus
(ii) the present value, as it was at the time of such member's retirement, of the amount payable to such member's Option 1 beneficiary or estate upon the death of the member as provided for by the applicable provisions of paragraph (e) of this subdivision; shall be equal to the Option 1 initial reserve determined for such pension component with respect to such member pursuant to the provisions of paragraph (b) of this subdivision.
(e) (i) Where such member dies before he or she has received payments on account of such pension component equal to the present value of such member's maximum pension as computed pursuant to paragraph (c) of this subdivision, the Option 1 benefit payable to the beneficiary or estate of such deceased member, by reason of such Option 1 selection in relation to such pension component, shall be the remainder obtained by subtracting from such present value determined pursuant to such paragraph (c) in relation to such pension component, the total of such Option 1 payments on account of such pension component received by or payable to such member for the period prior to his or her death.
(ii) In any case where the Option 1 beneficiary's benefit referred to in subparagraph (i) of this paragraph (e) is payable to such beneficiary in the form of an annuity payable in installments, or in the form of a lesser annuity, with provision that any unexhausted balance of the initial reserve for such lesser annuity shall be paid to a designated beneficiary or to an estate, such annuity or lesser annuity shall be determined to be the greater of the following in relation to the beneficiary entitled to such annuity or lesser annuity:
(A) such annuity or lesser annuity calculated on the basis of gender-neutral mortality tables and an interest assumption consisting of regular interest of seven per centum per annum, compounded annually; or
(B) such annuity or lesser annuity calculated on the basis of the female mortality tables applicable to such an annuity or lesser annuity or lesser annuity, as the case may be, and the regular interest applicable to such member, as such tables and interest were in effect immediately prior to the date of enactment (as certified pursuant to section forty-one of the legislative law) of this subdivision; or
(C) such annuity or lesser annuity calculated on the basis of the male mortality tables applicable to such an annuity or lesser annuity, as the case may be, and the regular interest applicable to such member, as such tables and interest were in effect immediately prior to the date of enactment of this subdivision.
(iii) Any unexhausted balance of an initial reserve payable to a designated beneficiary or to an estate after payment of a lesser annuity as described in subparagraph (ii) of this paragraph shall be the balance of such reserve remaining after there is subtracted from such reserve, the total amount of such lesser annuity payments paid or payable for the period prior to the annuitant's death.
(f) In relation to the Option 1 benefits determined pursuant to the method of computation set forth in this subdivision by reason of discontinuance by a discontinued member, the phrase "time of such member's retirement," as set forth in paragraphs (c) and (d) of this subdivision, shall be deemed, for the purposes of this subdivision, to mean the date of commencement of the retirement allowance of such discontinued member.
60. "Selection of mode of benefit."

(C) such retirement allowance (or portion thereof) determined on the basis of male mortality tables and the regular interest applicable to such member as of a time prescribed in such resolution; and
(ii) if such retirement allowance (or portion thereof) includes a variable annuity program benefit, then the part of such retirement allowance (or portion thereof) other than any variable annuity program benefit is determined in the manner provided for by subparagraph (i) of this paragraph and such variable annuity program benefit (or portion thereof) is the greatest of:
(A) such variable annuity program benefit (or portion thereof) determined on the basis of gender-neutral mortality tables and a uniform rate of interest of four percent, as such rate of interest is provided for in section 13-578 of the code; or
(ii) such variable annuity program benefit (or portion thereof) determined on the basis of female mortality tables and such uniform rate of interest of four percent; or
