(i) Notwithstanding the succeeding provisions of this item or the provisions of item (i-A), (ii), (iii) or (iv) of this subparagraph, for fiscal year two thousand eleven--two thousand twelve, and for each fiscal year thereafter, the amount of the normal contribution payable to the contingent reserve fund shall be determined pursuant to the provisions of item (v) of this subparagraph. Upon the basis of the latest mortality and other tables authorized by the applicable provisions of the rules and regulations and regular interest, the actuary shall determine, as of June thirtieth, nineteen hundred eighty and as of each succeeding June thirtieth, the amount of the total liability for all benefits provided in the rules and regulations, in articles eleven and fourteen of the retirement and social security law and in any other law prescribing benefits payable by the retirement system on account of all members and beneficiaries, excluding the liability on account of future increased-take-home-pay contributions, if any, and the liability for benefits attributable to the annuity savings fund and to the variable annuity savings fund, provided, however, that in determining such total liability as of June thirtieth, nineteen hundred ninety-five and as of each succeeding June thirtieth, the actuary shall include (A) the liability on account of future increased-take-home-pay contributions, if any, (B) the liability on account of future public employer obligations under the provisions of subdivision twenty of section two hundred forty-three of the military law, to pay in behalf of members qualifying for such benefit, member contributions with respect to certain periods of the military service of such members and (C) the liability for benefits attributable to the annuity savings fund and to the variable annuity savings fund, and provided further that in determining such total liability as of June thirtieth, nineteen hundred ninety-nine and as of each succeeding June thirtieth, the actuary shall include any other liability, as determined by the actuary, for benefits attributable to the variable annuity programs, and provided further that in determining such total liability as of June thirtieth, two thousand and as of each succeeding June thirtieth, the actuary shall include the amount, if any, as estimated by the actuary, of the total liability of the retirement system on account of payments which the retirement system may be required to make to any other fund without a corresponding offset in the liabilities of the retirement system.

(i-A) Notwithstanding any other provision of law to the contrary, for the purpose of calculating the amount of the normal contribution annually due from the board of education to the contingent reserve fund pursuant to item (iv) of this subparagraph in fiscal year two thousand five--two thousand six, and in each fiscal year thereafter, both the total liability of the retirement system, as calculated by the actuary in accordance with item (i) of this subparagraph, and the normal rate of contribution, as calculated by the actuary in accordance with items (ii) and (iii) of this subparagraph, shall be determined as of June thirtieth of the second fiscal year preceding the fiscal year in which the normal contribution is payable, provided, however, that (A) the actuary shall use for such calculations the mortality and other tables that are applicable at the time he or she performs such calculations; (B) the total funds on hand, as determined by the actuary pursuant to clause five of sub-item (A) of item (ii) of this subparagraph, shall be adjusted by adding to such amount the present value of all employer contributions required to be paid into the contingent reserve fund in the fiscal year next preceding the fiscal year in which the normal contribution is payable, as determined by the actuary; and (C) the present value of the prospective future salaries of all members, as computed by the actuary for the purposes of sub-item (C) of item (ii) of this subparagraph, shall be reduced by the present value of the salaries expected to be paid to all members in the fiscal year next preceding the fiscal year in which the normal contribution is payable, as determined by the actuary.

(ii) The normal rate of contribution shall be the rate per centum obtained:

(A) by adding together:

(1) (a) the amount obtained by adding together the present value of all required future revised unfunded accrued liability contributions and the present value of all required future payments of the nineteen hundred eighty unfunded accrued liability adjustment, determined pursuant to subparagraph six of this paragraph, if such adjustment is a charge; or

(b) the remainder obtained by subtracting from the present value of all required future revised unfunded accrued liability contributions, the present value of all future installments of the nineteen hundred eighty unfunded accrued liability adjustment required to be credited, if such nineteen hundred eighty adjustment is a credit;

(c) minus (whether (a) or (b) immediately preceding is applicable) the sum of the present value of all future installments of the nineteen hundred eighty-two unfunded accrued liability adjustment and the present value of all future installments of the nineteen hundred eighty-five unfunded accrued liability adjustment; and

(2) the present value of all required future balance sheet liability contributions, plus, in the case of the determination of the normal contribution payable in fiscal year nineteen hundred eighty--nineteen hundred eighty-one, the present value, as of June thirtieth, nineteen hundred eighty, of the payment of interest on the balance sheet liability as required by item (v) of subparagraph two of this paragraph (c); and

(3) the present value of all required future payments, pursuant to subdivision six of section seven of the rules and regulations, of installments of losses in excess of installments of gains on dispositions of securities within the meaning of such subdivision; and

(4) in the case of the determination of the normal contribution payable in each fiscal year commencing with fiscal year nineteen hundred ninety-five--nineteen hundred ninety-six, the present value of future member contributions of all members; and

(5) the total funds on hand, including the amount of any unpaid money appropriated pursuant to section nine of the rules and regulations and, in the case of the determination of the normal contribution payable in each fiscal year commencing with fiscal year nineteen hundred ninety-five--nineteen hundred ninety-six, including the amount in the annuity savings fund and in the variable annuity savings fund; and

(6) the present value of all other future installments of accrued liability contributions to the retirement system required by the applicable provisions of section 13-638.2 of the administrative code of the city of New York which are not covered by the preceding paragraphs of this subitem (A); and

(B) by subtracting from the amount of the total liability determined pursuant to item (i) of this subparagraph the sum resulting from the addition prescribed by sub-item (A) of this item; and

(C) by dividing the remainder resulting from the applicable subtraction prescribed by sub-item (B) of this item by one per centum of the present value of the prospective future salaries of all members, as computed by the actuary on the basis of the latest mortality and service tables adopted pursuant to subdivision two of section five of the rules and regulations, and on the basis of regular interest.

(iii) The normal rate of contribution determined by the actuary shall not be less than zero, shall be certified by the actuary after a valuation and shall continue in force until the next succeeding valuation and certification. The actuary shall make a valuation, as of June thirtieth of each year, of the assets and liabilities of the various funds created by the rules and regulations.

(iv)(A) The amount of the normal contribution annually due from the board of education to the contingent reserve fund in each city fiscal year, commencing with the nineteen hundred eighty--nineteen hundred eighty-one fiscal year and ending with the two thousand four--two thousand five fiscal year, shall be the amount obtained by multiplying the normal rate of contribution, as determined by the actuary as of June thirtieth next preceding such fiscal year, by the aggregate annual salaries of the members on such June thirtieth next preceding such fiscal year in which such amount is due and shall be payable in such fiscal year next following such June thirtieth, together with such regular interest thereon which may be due, if any, as calculated by the actuary.

(B) The amount of the normal contribution annually due from the board of education to the contingent reserve fund in each city fiscal year, commencing with the two thousand five--two thousand six fiscal year, shall be the amount obtained by multiplying the normal rate of contribution, as determined by the actuary as of the second June thirtieth preceding the fiscal year in which the normal contribution is payable, in accordance with the provisions of items (i-A), (ii) and (iii) of this subparagraph, by the aggregate amount of the salaries expected to be paid to the members during the fiscal year in which the normal contribution is payable, as determined by the actuary, and such normal contribution shall be payable in the second fiscal year following the June thirtieth as of which the normal rate of contribution is determined, together with such regular interest thereon which may be due, if any, as calculated by the actuary.

(C) In the case of the normal contribution payable in the nineteen hundred eighty--nineteen hundred eighty-one fiscal year and in any subsequent fiscal year, the term "regular interest," as used in this item (iv) shall mean regular interest as defined by the applicable provisions of subparagraph three or subparagraph four of paragraph (b) of this subdivision.

(v) (A) Notwithstanding the preceding items of this subparagraph or any other provision of law to the contrary, the normal contribution payable to the contingent reserve fund in fiscal year two thousand eleven--two thousand twelve, and in each fiscal year thereafter, shall be the entry age normal contribution, as determined by the actuary pursuant to this item in a manner consistent with the entry age actuarial cost method. The actuary shall determine the entry age normal contribution for each such fiscal year as of June thirtieth of the second fiscal year preceding the fiscal year in which such normal contribution is payable, based on the latest mortality and other tables applicable at the time he or she performs such calculations, and the valuation rate of interest as provided for the retirement system in paragraph two of subdivision b of section 13-638.2 of the administrative code of the city of New York.

(B) In calculating the entry age normal contribution payable in any such fiscal year pursuant to this item, the actuary, in his or her discretion, may make certain adjustments in the calculation methodology, provided that such adjustments are generally accepted as consistent with the entry age actuarial cost method, and are designed, in general, to fund, on a level basis over the working lifetimes of members from their ages at entry, the actuarial present value of benefits to which such members are expected to become entitled, as determined by the actuary. Such generally accepted adjustments in the calculation methodology, in the discretion of the actuary, may include, but are not limited to, the calculation of the entry age normal contribution (1) on an individual member basis by calculating the amount of the entry age normal contribution attributable to each individual member, and then adding together such individual member amounts, (2) on an aggregate basis for all members or (3) on any combination of an individual member basis and an aggregate basis which is consistent with the entry age actuarial cost method, and the preceding provisions of this sub-item.

(C) For each such fiscal year, the actuary, in his or her discretion, shall determine, in accordance with the provisions of sub-item (B) of this item, the methodology for calculating the entry age normal contribution payable for that particular fiscal year.

(D) The methodology determined by the actuary in accordance with sub-item (C) of this item may provide for the actuary to calculate the entry age normal contribution on an individual member basis by (1) multiplying the entry age normal contribution rate for each individual member, as determined by the actuary, by the salary expected to be paid to that member during the fiscal year in which such normal contribution is payable, and (2) calculating the sum of the individual entry age normal contributions attributable to all such members. The actuary, in his or her discretion, may make any adjustments to such methodology for determining the entry age normal contribution on an individual basis which he or she deems appropriate, and which are consistent with the provisions of sub-item (B) of this item.

(E) In the alternative, the methodology determined by the actuary in accordance with sub-item (C) of this item may provide for the actuary to calculate the entry age normal contribution on an aggregate basis by multiplying the entry age normal contribution rate for all members in the aggregate, as determined by the actuary, by the aggregate amount of the salaries expected to be paid to all members during the fiscal year in which the normal contribution is payable. The actuary, in his or her discretion, may make any adjustments to such methodology for determining the entry age normal contribution on an aggregate basis which he or she deems appropriate, and which are consistent with the provisions of sub-item (B) of this item.

(F) In the alternative, the methodology determined by the actuary in accordance with sub-item (C) of this item may provide for the calculation of the entry age normal contribution on any other basis which the actuary deems appropriate, and which is consistent with the entry age actuarial cost method and the provisions of sub-item (B) of this item.

(G) (1) Where the methodology determined by the actuary in accordance with sub-item (C) of this item requires the determination of an entry age normal contribution rate for each individual member in order to calculate the entry age normal contribution for each individual member, the actuary shall determine such rate for each such member in accordance with the entry age actuarial cost method, and such rate, as determined by the actuary for each such member, shall be consistent with a method designed, in general, to fund, on a level basis over the working lifetime of that particular member from his or her age at entry, the actuarial present value of benefits to which such member is expected to become entitled, as determined by the actuary.

(2) Where the methodology determined by the actuary in accordance with sub-item (C) of this item requires the determination of an entry age normal contribution rate for all members in the aggregate in order to calculate the entry age normal contribution for all members in the aggregate, the actuary shall determine such rate in accordance with the entry age actuarial cost method, and such rate, as determined by the actuary, shall be consistent with a method designed, in general, to fund, on a level basis over the working lifetimes of members from their ages at entry, the actuarial present value of benefits to which such members are expected to become entitled, as determined by the actuary.

(5) Unfunded accrued liability contributions.--(i) The original unfunded accrued liability contribution shall be an amount which, if paid to the contingent reserve fund in forty equal annual installments, commencing with payment of a first installment in the city's nineteen hundred seventy-seven--nineteen hundred seventy-eight fiscal year, would be the actuarial equivalent, on the basis of five and one-half percentum interest and the actuarial tables in effect as of July first, nineteen hundred seventy-seven, of the difference between (A) the accrued liability (excluding the liability for benefits attributable to the annuity savings fund and the variable annuity savings fund) on June thirtieth, nineteen hundred seventy-five and (B) the total funds on hand, excluding the amount in the annuity savings fund and the variable annuity savings fund, but including the amount of any unpaid moneys appropriated pursuant to section nine of the rules and regulations.

The provisions of such paragraph f shall cease to be effective on July first, nineteen hundred seventy-seven.

(B) To the amount of the difference constituting the unfunded accrued liability as of June thirtieth, nineteen hundred seventy-five heretofore determined pursuant to the provisions of this subparagraph, as in effect on July first, nineteen hundred seventy-seven, there shall be added interest thereon at the rate of five and one-half per centum per annum for the period from July first, nineteen hundred seventy-five to June thirtieth, nineteen hundred eighty.

(C) There shall be computed, in the manner provided in sub-item (D) of this item, the discounted value of each of the installments of the unfunded accrued liability contribution which, in the absence of the enactment of chapter nine hundred fifty-seven of the laws of nineteen hundred eighty-one, were payable or would have been payable in the city's nineteen hundred seventy-seven--nineteen hundred seventy-eight, nineteen hundred seventy-eight--nineteen hundred seventy-nine, nineteen hundred seventy-nine--nineteen hundred eighty, nineteen hundred eighty--nineteen hundred eighty-one and nineteen hundred eighty-one--nineteen hundred eighty-two fiscal years.

(D) Such discounted value of each such installment referred to in sub-item (C) of this item shall be computed as of January first of the city's second fiscal year preceding the fiscal year in which such installment was payable or would have been payable and on the basis of five and one-half per centum interest per annum on the amount of such installment.

(E) There shall be computed with respect to such discounted value of each such installment, interest thereon from January first of such second fiscal year preceding the fiscal year in which such installment was or would have been payable to June thirtieth, nineteen hundred eighty at the rate of five and one-half per centum per annum.

(F) The discounted values of all of such installments with respect to such fiscal years, computed as provided for in sub-items (C) and (D) of this item, together with interest on each such installment as provided for in sub-item (E) of this item, shall be added together.

(G) From the sum computed pursuant to sub-item (B) of this item, the sum computed pursuant to sub-item (F) of this item shall be subtracted.

(H) With respect to each city fiscal year occurring during the period beginning on July first, nineteen hundred eighty and ending on June thirtieth, nineteen hundred eighty-two, the revised unfunded accrued liability contribution shall be the annual installment, applicable to such fiscal year, of an amount which, if paid to the contingent reserve fund in thirty-five equal annual installments, commencing with payment of a first installment in the city's nineteen hundred eighty--nineteen hundred eighty-one fiscal year, would be the actuarial equivalent, on the basis of seven and one-half per centum interest per annum, of the remainder computed pursuant to sub-item (G) of this item.

(I) With respect to each city fiscal year occurring during the period beginning on July first, nineteen hundred eighty-two and ending on June thirtieth, nineteen hundred eighty-eight, the revised unfunded accrued liability contribution shall be the annual installment, applicable to such fiscal year, of an amount which, if paid to the contingent reserve fund in thirty-three equal annual installments, commencing with payment of a first installment in the city's nineteen hundred eighty-two--nineteen hundred eighty-three fiscal year, would be the actuarial equivalent, on the basis of eight per centum interest per annum, of the present value, as of June thirtieth, nineteen hundred eighty-two on the basis of seven and one-half per centum interest per annum, of those installments of the unfunded accrued liability contribution computed pursuant to sub-item (H) of this item (ii), which installments are hypothetically allocated by such sub-item (H) to designated city fiscal years succeeding June thirtieth, nineteen hundred eighty-two.

(J) With respect to each city fiscal year occurring during the period beginning on July first, nineteen hundred eighty-eight and ending on June thirtieth, two thousand fifteen, the revised unfunded accrued liability contribution shall be the annual installment, applicable to such fiscal year, of an amount which, when paid to the contingent reserve fund in twenty-seven equal annual installments, commencing with payment of a first installment in the city's nineteen hundred eighty-eight--nineteen hundred eighty-nine fiscal year, shall be the actuarial equivalent, on the basis of eight and one-quarter per centum interest per annum, of the present value, as of June thirtieth, nineteen hundred eighty-eight on the basis of eight per centum interest per annum, of those installments of the unfunded accrued liability contribution computed pursuant to sub-item (I) of this item (ii), which installments are hypothetically allocated by such sub-item (I) to designated city fiscal years succeeding June thirtieth, nineteen hundred eighty-eight.

(6) (i) The nineteen hundred eighty unfunded accrued liability adjustment shall be an amount determined as prescribed in items (ii), (iii), (iv) and (v) of this subparagraph.

(ii) (A) Upon the basis of the actuarial tables in effect as of June thirtieth, nineteen hundred eighty for valuation purposes and interest at the rate of seven and one-half per centum per annum, there shall be determined, as of June thirtieth, nineteen hundred eighty, the amount of the total liability for all benefits provided in the rules and regulations, in articles eleven and fourteen of the retirement and social security law and in any other law prescribing benefits payable by the retirement system on account of all members and beneficiaries, excluding the liability on account of future increased-take-home pay contributions, if any, and the liability for benefits attributable to the annuity savings fund and to the variable annuity savings fund.

In the event that any such extension is directed by a resolution of the retirement board adopted prior to the date of enactment of this subparagraph nineteen, such extension, upon the enactment of this subparagraph, shall be valid and effective as of the date of adoption of such resolution in the same manner and to the same extent as if such enactment had occurred before such date of adoption.

(ii) Where an actuarial equivalent benefit is required by retirement board resolution to be determined for any seven percent member for actuarial equivalent benefit purposes through the use of the modified Option 1 pension computation formula (as defined in subparagraph thirteen of paragraph (b) of this subdivision), the actuarial interest assumptions used in making such determination shall be as prescribed in such formula.

(iii) Where it is provided by board resolution that a portion of an actuarial equivalent benefit shall be determined for any seven percent member for actuarial equivalent benefit purposes on the basis of gender-neutral mortality tables, and that the remainder of such benefit shall be determined on the basis of mortality tables which are not gender-neutral, regular interest at the rate of seven per centum per annum, compounded annually, shall be used as the actuarial interest assumption for determining the portion of such benefit required by such resolution to be determined on the basis of gender-neutral mortality tables and such rate of regular interest shall not apply to the determination of the remainder of such benefit.

(2) Notwithstanding that the process of determining whether a member is a seven percent member for actuarial equivalent benefit purposes may include, for the purpose of ascertaining the highest applicable benefit, alternative hypothetical benefit calculations utilizing a rate of regular interest other than such rate of seven per centum, nothing contained in paragraph (c) of this subdivision or in subparagraph one of this paragraph shall be construed as requiring that in the determination of any actuarial equivalent benefit (other than a variable annuity program benefit) payable to or on account of any member who is not a seven percent member for actuarial equivalent benefit purposes, any rate of interest be used other than regular interest, as prescribed by the applicable provisions of subdivision fifteen of section two of the rules and regulations.

(e) The provisions of subparagraph one of paragraph (d) of this subdivision shall not apply to any person who, prior to August first, nineteen hundred eighty-three, retired as a member of the retirement system for age or service or superannuation or for ordinary or accident disability and who was such a retiree immediately prior to such August first; provided, however, that where any such retiree retired pursuant to subdivision two of section ten of the rules and regulations or retired for ordinary or accident disability, and such retiree re-entered or re-enters education service and on or after July thirty-first, nineteen hundred eighty-three, was or is restored to membership in the retirement system, the provisions of such subparagraph one, from and after such date of restoration to membership, shall apply to such restored member with respect to determination of any actuarial equivalent benefit which is both (1) a benefit to which he or she became or becomes entitled upon his or her subsequent retirement or subsequent discontinuance of service so as to qualify for benefits, and (2) a benefit which is not a continuation, without change, of a benefit which had previously become payable to him or her by reason of his or her prior retirement; provided further that nothing contained in the preceding provisions of this paragraph shall be construed as making subparagraph one of such paragraph (d) applicable to any such member who was not or is not a seven percent member for actuarial equivalent benefit purposes at such time of subsequent retirement or subsequent discontinuance of service.

(f) (1) Subject to the provisions of subparagraph two of this paragraph, the provisions of subparagraph one of paragraph (d) of this subdivision shall not apply to any Tier I or Tier II member who, (A) prior to August first, nineteen hundred eighty-three discontinued service under such circumstances that such member became a discontinued member and acquired a vested right to receive a retirement allowance pursuant to section thirty-two of the rules and regulations (and, in the case of a Tier II member, article eleven of the retirement and social security law), and (B) was such a discontinued member immediately prior to such August first.

(2) If such a discontinued member returned or returns to education service and on or after July thirty-first, nineteen hundred eighty-three and before payability of his or her retirement allowance as such member began or begins, again became or becomes an active member pursuant to the applicable provisions of such section thirty-two, the provision of subparagraph one of such paragraph (d) shall apply to him or her on and after the date of such resumption of active membership; provided that nothing contained in the preceding provisions of this subparagraph shall be construed as making the provisions of subparagraph one of such paragraph (d) applicable to any such member who was not or is not a seven percent member for actuarial equivalent benefit purposes at the time of subsequent retirement or subsequent discontinuance of service so as to qualify for benefits.

(3) Subject to the provisions of subparagraph four of this paragraph, the provisions of subparagraph one of paragraph (d) of this subdivision shall not apply to any Tier III or Tier IV member who, (i) prior to August first, nineteen hundred eighty-three, terminated employment under such circumstances that such member became a Tier III member entitled to a vested benefit or a Tier IV member entitled to vested benefit and (ii) had such status immediately prior to such August first.

(4) If a member who became entitled to a vested benefit as described in subparagraph three of this paragraph returned or returns to education-service and, on or after July thirty-first, nineteen hundred eighty-three and before payability of his or her vested benefit began or begins, resumed or resumes status as an active member of the retirement system, the provisions of subparagraph one of paragraph (d) of this subdivision shall apply to him or her on and after the date of such resumption of active membership, providing that nothing contained in the preceding provisions of this subparagraph shall be construed as making the provisions of subparagraph one of such paragraph (d) applicable to any such member who was not or is not a seven percent member for actuarial equivalent benefit purposes at the time of subsequent retirement or of subsequent discontinuance of service so as to qualify for benefits.

(g)(1) Subject to the provisions of subparagraph two of this paragraph and to the provisions of paragraph (i) of this subdivision, the selection of mode of benefit (as defined in subparagraph fourteen of paragraph (b) of this subdivision) which, prior to the termination date of eligibility for option re-selection (as defined in subparagraph nineteen of paragraph (b) of this subdivision), a person entitled to a recomputation of benefits (as defined in subparagraph sixteen of such paragraph (b)) made or makes in relation to the retirement allowance (or any component thereof) which became or becomes payable to him or her prior to such termination date of eligibility for option re-selection, shall be the selection of mode of benefit applicable to the recomputed retirement allowance (or any corresponding component thereof) to which he or she is entitled under the best-of-three-computations method or the gender-neutral computations method, and any such person entitled to a recomputation of benefits pursuant to the best-of-three-computations method or the gender-neutral computations method shall not be entitled to make any change in such selection of mode of benefit.

(2) (i) Notwithstanding the provisions of subparagraph one of this paragraph, a person entitled to a recomputation of benefits shall be entitled, to the extent and in the manner prescribed in the succeeding items of this subparagraph, to change the original selection of mode of benefit applicable to the retirement allowance (or any component thereof) which became or becomes payable to him or her prior to the termination date of eligibility for option re-selection.

(ii) In any case where the original selection of mode of benefit of a person entitled to a recomputation of benefits was a selection of a joint and survivor option (as defined in subparagraph seventeen of paragraph (b) of this subdivision), no change from such original selection of a joint and survivor option may be made under this subparagraph to any other selection of mode of benefit if the designated beneficiary selected with respect to such joint and survivor option by such person entitled to a recomputation is not alive at the time of filing of the form whereby such person entitled to a recomputation seeks to change, pursuant to this subparagraph, his or her original selection of such joint and survivor option.

(iii) Except for a change of selection of mode of benefit prohibited by item (ii) of this subparagraph, any original selection of mode of benefit may be changed pursuant to this subparagraph to another selection of mode of benefit, provided all of the conditions set forth in items (iv), (vi) and (viii) of this subparagraph are met.

(iv) Subject to the provisions of items (vii) and (viii) of this subparagraph, a person entitled to a recomputation of benefits may, pursuant to this subparagraph, effect any such permissible change of his or her original selection of mode of benefit by executing, acknowledging and filing with the retirement system, within the applicable period of time prescribed by item (vi) of this subparagraph, a new selection of mode of benefit. If the original selection of mode of benefit of the person filing such new selection was a selection of a joint and survivor option, such new selection shall be void and of no effect unless (a) the designated beneficiary named in such original selection of a joint and survivor option signs and acknowledges, in the form for such new selection of mode of benefit, a consent to such changed selection of mode of benefit, and (b) such original designated beneficiary is alive on the date of filing of such new selection.

(v) The retirement system shall mail to each person entitled to a recomputation of benefits a letter showing amounts of benefits, as recomputed for such person under the best-of-three-computations method or the gender-neutral computations method, for modes of benefit other than joint and survivor options, together with a statement advising such person that upon request, the amounts of recomputed benefits under joint and survivor options will be provided.

(iii) the death, on or after such August first, of a member: the rate of interest used to determine such variable annuity program benefit shall be that prescribed by section forty-four of the rules and regulations.

(ii) that the benefit payable, upon the death of the member making such election, to his or her beneficiary or estate shall be the difference between such Option 1 initial reserve and the total of the payments of such pension component received by or payable to such member for the period prior to his or her death; and

(iii) that where any member subject to the modified Option 1 pension computation formula retired before the effective date of the retirement board resolution adopted pursuant to subparagraph one of this paragraph, and where the first payment on account of the retirement allowance of any discontinued member subject to such formula was made before the effective date of such resolution, such retiree or discontinued member, within such period of time after such effective date and in accordance with such procedures as are prescibed in such resolution, may elect the method of Option 1 benefit determination set forth in items (i) and (ii) of this subparagraph.

(e) Notwithstanding any other provision of law to the contrary, the rules and regulations adopted pursuant to this section shall be deemed to be amended to provide that if a retiree or vestee who: (1) has met the criteria of paragraph (d) of this subdivision and retired on a service or disability retirement, would have met the criteria if not already retired on an accidental disability, or was separated from service with a vested right to deferred payability of a retirement allowance; and (2) has not been retired for more than twenty-five years; and (3) dies from a qualifying World Trade Center condition, as defined in section two of the retirement and social security law, as determined by the applicable head of the retirement system or applicable medical board, then unless the contrary be proven by competent evidence, such retiree or vestee shall be deemed to have died as a natural and proximate result of an accident sustained in the performance of duty and not as a result of willful negligence on his or her part. Such retiree's or vestee's eligible beneficiary, as set forth in title twenty-one of the rules and regulation, shall be entitled to an accidental death benefit as provided by title twenty-one of the rules and regulations, however, for the purposes of determining the salary base upon which the accidental death benefit is calculated, the retiree or vestee shall be deemed to have died on the date of his or her retirement or separation from service with vested rights. Upon the retiree's or vestee's death, the eligible beneficiary shall make a written application to the head of the retirement system within the time for filing an application for an accidental death benefit as set forth in title twenty-one of the rules and regulations requesting conversion of such retiree's service, vested right or disability retirement benefit to an accidental death benefit. At the time of such conversion, the eligible beneficiary shall relinquish all rights to the prospective benefits payable under the service or disability retirement benefit, or vested right to such benefit, including any post-retirement death benefits, since the retiree's or vestee's death. If the eligible beneficiary is not the only beneficiary receiving or entitled to receive a benefit under the service or disability retirement benefit (including, but not limited to, post-retirement death benefits or benefits paid or payable pursuant to the retiree's option selection), or that will be eligible under the vested right the accidental death benefit payments to the eligible beneficiary will be reduced by any amounts paid or payable to any other beneficiary.

Such member's eligible beneficiary, as set forth in title twenty-one of the rules and regulations shall be entitled to an accidental death benefit provided he or she makes written application to the head of the retirement system as set forth in title twenty-one of the rules and regulations.
