(a) The board of education of a city school district of a city having a population of one hundred thousand or more shall have power to establish a retirement system for all civil employees permanently employed by said board other than superintendents and teachers who may now be retired under the provisions of other retirement laws. In any such city in which there is a bureau of compulsory education, school census, and child welfare established under the provisions of this chapter, all persons, except for attendance teachers and specially certificated attendance officers who are first employed by a board of education of a city having a population of one million or more, beginning on the first day of September, nineteen hundred sixty-eight, and further except for the director of attendance, assistant director of attendance, chief attendance officer, division supervising attendance officer, and district supervising attendance officer, supervisors of school social workers, who were first employed by a board of education of a city having a population of one million or more, beginning on the first day of September nineteen hundred sixty-nine, of which such a bureau of compulsory education, school census, and child welfare consists shall be members of the retirement system created in accordance with the provisions of this section, provided that any such person who on May fourth, nineteen hundred twenty-six, was a member of another retirement system in such city may continue such membership so long as he or she holds an office or position in such bureau. Transfer of membership of any such persons from another retirement system to a retirement system as herein provided shall be made in accordance with the provisions of § 59 of the civil service law. The board of education of such city shall adopt appropriate rules and regulations for the government, management and control of the retirement of said employees; except that in regard to the actions of the governing board of a retirement system governed by such rules and regulations, the concurrence of one employee representative and one non-employee representative shall be necessary for an act of such board, and there shall be no fewer than two employee representatives of such board. Before they become effective such rules and regulations must be approved by the board of estimate, or the board of estimate and apportionment in a city having such body, and in a city not having such body by the common council or such other officers or bodies as have the management and control of financial affairs similar to that exercised by such board of estimate or board of estimate and apportionment. The board of estimate or the board of estimate and apportionment in a city having such body, and in other cities the officers or bodies performing the functions similar to those of a board of estimate or a board of estimate and apportionment shall appropriate annually the sum necessary to pay the expenses of the administration of this section, except that in the city of New York such appropriations shall be made pursuant to chapter six of the New York city charter, and also to pay such pensions to the employees herein described as they shall be entitled to receive annually under the rules and regulations prescribed by the board of education and approved by the said board of estimate or board of estimate and apportionment or other authorities.

(b) (1) The rules and regulations prescribed by the board of education and approved by the board of estimate or the board of estimate and apportionment or other authorities named herein shall provide for the annual payment of a pension which shall be a per centum of the average annual personal compensation of an employee for the five years of service immediately preceding his retirement, except as otherwise provided in subparagraph two of this paragraph (b).

(2) Such rules and regulations so prescribed and approved with respect to any such retirement system established in the city school district of a city having a population of one million or more may provide for the annual payment of a pension which shall be a per centum of the compensation of an employee during any period designated in such rules and regulations; provided, however, that such period shall in no event be less than one year or more than five years.

2. In a city having a population of one million or more and having a teachers' retirement board, changes, alterations, amendments or modifications in the rules and regulations established for the administration of this section shall be adopted as follows:

The board of education of said city may adopt and shall submit such changes, alterations, amendments or modifications, hereinafter in this subdivision referred to as changes, to said teachers' retirement board for approval. Said teachers' retirement board shall within thirty days after the submission to it of such changes transmit to said board of education a statement in writing setting forth which of such changes it approves and which it disapproves, if any, and the reasons for such disapproval. If said teachers' retirement board shall approve of all of such changes, then such changes shall immediately become effective and in full force and operation.

If said teachers' retirement board shall disapprove of all or any of such changes and if said board of education and said teachers' retirement board within thirty days thereafter shall fail to agree upon changes in place of the changes so disapproved, then the changes shall be submitted by said board of education within ten days after the lapse of said thirty days to the commissioner of education who shall have full power to approve, alter or modify the changes disapproved by said teachers' retirement board, and the action of the commissioner of education shall be final, and thereupon the changes approved by said teachers' retirement board and the changes as approved, altered or modified by the commissioner of education shall immediately become effective and in full force and operation.

Should said teachers' retirement board fail either to approve or to disapprove all or any of such changes submitted to it as herein provided, then such changes not approved or not disapproved shall at the expiration of the thirty days immediately following their submission to said teachers' retirement board be deemed to have been approved by said teachers' retirement board and such changes shall immediately become effective and in full force and operation.

Said teachers' retirement board and the trustees of any variable annuity funds created by said rules and regulations may negotiate an agreement whereby said variable annuity funds are commonly invested with the variable annuity funds of said teachers' retirement board. In such event, final authority for investing such funds shall rest with the teachers' retirement board for the period of such agreement. Such agreement shall be for a period not to exceed five years but may be renewed.

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 § 243 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. No contribution or payment to the contingent reserve fund of the retirement system shall be made under the provisions of paragraph f of subdivision three of section eight of the rules and regulations in the nineteen hundred seventy-seven–nineteen hundred seventy-eight fiscal year of the city or in any subsequent city fiscal year. The provisions of such paragraph f shall cease to be effective on July first, nineteen hundred seventy-seven.

(ii) (A) The revised unfunded accrued liability contribution shall be an amount determined as prescribed in sub-items (B), (C), (D), (E), (F), (G), (H), (I) and (J) of this item.

(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.

(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 11 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.

(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.

(vi) The period of time within which any such person entitled to a recomputation may file a new selection of mode of benefit as provided for in items (iii) and (iv) of this subparagraph shall be sixty days after the date of issuance set forth in such letter mailed to such person pursuant to item (v) of this subparagraph; provided, however, that if, pursuant to the request of such person, a later letter setting forth benefits information in relation to a new selection of a mode of benefit is mailed to such person by the retirement system, such period of time for filing a new selection of mode of benefit shall be thirty days after the date of issuance set forth in such later letter.

(vii) Upon the filing of a new selection of mode of benefit pursuant to this subparagraph 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.

(viii) No new selection of mode of benefit filed pursuant to the preceding items of this subparagraph 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 age or 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 discontinued sanitation 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.

(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.

(2) the terms "member," "Tier I member" and "Tier II member" shall have the meanings set forth in subparagraphs one, four and five, respectively, of subparagraph (b) of subdivision seventeen of this section.

(b) the following terms, as used in this subdivision, shall have the following meanings, unless a different meaning is plainly required by the context:

(1) "Basic rate of contribution as a Tier I or Tier II member." (i) Subject to the provisions of clauses (ii) and (iii) of this subparagraph one, the term "basic rate of contribution as a Tier I or Tier II member" shall mean the proportion of the earnable compensation of a Tier I member or Tier II member required by the provisions of subparagraph (i) of paragraph f of subdivision one of § 8 of the rules and regulations and any other applicable provisions of the rules and regulations or law to be deducted from the personal compensation of such member as his or her member contributions, exclusive of any increase in such contributions resulting from an election by such member pursuant to law to effect such an increase, or any decrease in such contributions on account of any program for increased-take-home-pay or pursuant to subdivision one of § 138-b of the retirement and social security law (relating to election to decrease member contributions by contributions due on account of social security coverage).

(ii) In any case where it is provided in the rules and regulations that the deduction from a member's compensation on account of member contributions required to be made by a Tier I member or Tier II member shall not be in excess of fifteen per centum unless the member so elects, and such member makes such election, any per centum of such deduction in excess of fifteen per centum with respect to such member shall not be included in such member's basic rate of contribution as a Tier I or Tier II member.

(iii) In any case where a Tier I member or Tier II member who is a fifty-five-year-increase-service-fraction member (as defined in subdivision thirty-one of section two of the rules and regulations) has elected or elects, pursuant to paragraph g of subdivision one of section eight of the rules and regulations, to contribute to the retirement system at a rate one per centum less than such member's normal rate of contribution, such member's basic rate of contribution as a Tier I or Tier II member, during any period wherein such election is in effect, shall be one per centum less than such member's normal rate of contribution as a fifty-five-year-increased-service-fraction member. In any case where any such member elects pursuant to such paragraph g to discontinue such reduction, such election to discontinue shall not be deemed, for the purposes of subparagraph four of this paragraph (b) to be an election to increase member contributions above the level prescribed by the member's basic rate of contribution as a Tier I or Tier II member, and upon such discontinuance, such member's basic rate of contribution as a Tier I or Tier II member shall be his or her normal rate of contribution as a fifty-five-year-increased-service-fraction member.

(2) "Contributing Tier I or Tier II member." With respect to any payroll period as to which the status of a Tier I member or Tier II member as to required member contributions is to be determined, the term "contributing Tier I or Tier II member" shall mean any Tier I member or Tier II member other than any Tier I member or Tier II member who is not required to contribute during such payroll period because of his or her then currently effective election, pursuant to subparagraph f of paragraph one of section eight of the rules and regulations, not to contribute.

(3) "Employer responsible for pick up." The public employer by which a Tier I member or Tier II member is employed.

(4) "Tier I or Tier II member contributions eligible for pick up by the employer." (i) With respect to any payroll period for a contributing Tier I or Tier II member (as defined in subparagraph two of this paragraph (b)), the amount of member contributions which, in the absence of a pick up program applicable to such member pursuant to this subdivision, would be required by law to be deducted, on account of such member's basic rate of contribution as a Tier I or Tier II member (as defined in subparagraph one of this paragraph), from the personal compensation of such member for such payroll period, after (A) giving effect to any reduction in such contributions required under any program for increased-take-home-pay or pursuant to subdivision one of § 138-b of the retirement and social security law and (B) excluding any deductions from such compensation (or redeposits, restorations or payments) on account of (1) loans or withdrawal of excess contributions or (2) any election by any such member, pursuant to any applicable provision of the rules and regulations, to increase his or her member contributions above the level prescribed by his or her basic rate of contribution as a Tier I or Tier II member or (3) any other cause not attributable to the member's basis rate of contribution as a Tier I or Tier II member after reduction in such rate, if any, as described in item (A) of this clause (i).

(ii) If no deductions on account of any such member's basic rate of contribution as a Tier I or Tier II member are required by the rules and regulations to be made from the personal compensation of such member for any payroll period, such member shall not have, for such payroll period, any Tier I or Tier II member contributions eligible for pick up by the employer. The amount of Tier I or Tier II member contributions eligible for pick up by the employer of any Tier I member or Tier II member for any payroll period shall be determined solely on the basis of personal compensation paid to such member for such payroll period by his or her public employer. A Tier I member or Tier II member shall not have any Tier I or Tier II member contributions eligible for pick up by the employer with respect to any payroll period for which he or she is not paid personal compensation by his or her public employer.

(5) "Starting date for pickup." The first day of the first whole payroll period commencing after the date which is sixty days after the internal revenue service shall have issued a ruling that member contributions picked up pursuant to this subdivision are not includible as gross income for federal income tax purposes until distributed or made available.

(c) Notwithstanding any other provision of the law to the contrary, on and after the starting date for pick up, the employer responsible for pick up shall pick up and pay into the annuity savings fund (subject to the provisions of subparagraph four of paragraph (f) of this subdivision) the Tier I or Tier II member contributions eligible for pick up by the employer which each Tier I member and Tier II member would otherwise be required to make on and after such starting date.

(c-1) Notwithstanding any other provision of law to the contrary, the employer responsible for pick up shall, in the case of a member who is a participant in the age fifty-five improved benefit retirement program (as defined in paragraph ten of subdivision a of § 445-d of the retirement and social security law), pick up and pay to the retirement system all additional member contributions which otherwise would be required to be deducted from such member's compensation pursuant to paragraph three of subdivision d of such section four hundred forty-five-d, and shall effect such pick up on each and every payroll of such participant for each and every payroll period with respect to which such paragraph three otherwise would require such deductions.

(c-2) Notwithstanding any other provision of law to the contrary, the employer responsible for pick up shall, in the case of a member who is a participant in the age fifty-five retirement program (as defined in paragraph ten of subdivision a of § 445-i of the retirement and social security law), pick up and pay to the retirement system all additional member contributions which otherwise would be required to be deducted from such member's compensation pursuant to paragraph three of subdivision d of § 445-i of the retirement and social security law, and shall effect such pick up on each and every payroll of such participant for each and every payroll period with respect to which such paragraph three otherwise would require such deductions.

(d) An amount equal to the amount of such picked up contributions shall be deducted by the employer responsible for pick up from the personal compensation of such member (as such compensation would be in the absence of a pick up program applicable to him or her hereunder) and shall not be paid to such member. Such deduction shall be effected by means of subtraction from such member's current personal compensation (as so defined), or offset against future pay increases, or a combination of such methods.

(e) (1) * The member contributions and additional member contributions picked up pursuant to this subdivision for any Tier I member or Tier II member shall be paid by the employer responsible for pick up in lieu of an equal amount of the member contributions and additional member contributions otherwise required to be paid by such member under the provisions of the rules and regulations or the retirement and social security law, and shall be deemed to be and treated as employer contributions pursuant to sub§ of the United States internal revenue code, as amended, for the purposes, under federal law, for which such subsection h so classifies such picked up contributions.

* (3) Employer pick-up of contributions in respect of previous service or military service. Notwithstanding any other provision of law, any member eligible to purchase credit for previous service with a public employer pursuant to this § of the retirement and social security law, may elect to purchase any or all of such service by executing a periodic payroll deduction agreement where and to the extent such elections are permitted by the retirement system by rule or regulation. Such agreement shall set forth the amount of previous service or military service being purchased, the estimated total cost of such service credit, and the number of payroll periods in which such periodic payments shall be made. Such agreement shall be irrevocable, shall not be subject to amendment or modification in any manner, and shall expire only upon completion of payroll deductions required therein. Notwithstanding the foregoing, any member who has entered into such a payroll deduction agreement and who terminates employment prior to the completion of the payments required therein shall be credited with any service as to which such member shall have paid the contributions required under the terms of the agreement.
