        (2) Such gain or loss shall be treated in the manner prescribed by the

      during the period beginning on July first, nineteen  hundred  sixty-nine
      and  ending on June thirtieth, nineteen hundred seventy-eight, the first
      of such installments shall be credited  in  favor  of  such  responsible
      public  employer in the second city fiscal year succeeding that in which

      one-half per centum shall be used.
        (5)  With respect to each present value computed pursuant to paragraph
      four of this subdivision c, there shall be computed a  number  of  equal
      annual  installments  of  credit  in  favor  of  the  responsible public

      uncredited  installments  referred  to  in  such paragraph four, and the
      aggregate of which computed installments, on the basis of crediting  the
    
      first  of  such  installments to such responsible public employer in the
      city's nineteen hundred eighty--nineteen hundred eighty-one fiscal  year
      and one of such installments in each subsequent fiscal year until all of
      such  installments are so credited, shall be the actuarial equivalent of
      such present value referred to in such paragraph four. For  the  purpose
      of  making  such computation, an interest rate of seven and one-half per
      centum per annum shall be used.
        (6) (a) One of such installments computed pursuant to  paragraph  five
      of  this  subdivision  c  shall be credited in favor of such responsible
      public employer in each of the city's nineteen hundred  eighty--nineteen

      eighty-two fiscal years.
        (b) (i) In each city fiscal year occurring during the period beginning
      on July first, nineteen hundred eighty-two and ending on June thirtieth,

      responsible  public  employer an installment computed in accordance with
      items (ii) and (iii) of this subparagraph (b).
        (ii) With respect to each present value computed pursuant to paragraph
      four of  this  subdivision  c,  there  shall  be  computed  as  of  June
      thirtieth,  nineteen hundred eighty-two, using an interest rate of seven
      and one-half per centum per annum,  the  present  value  of  the  annual
      installments  of  credit  in  favor  of  the responsible public employer
      determined in accordance with paragraph five of this subdivision  c  and
      allocated to fiscal years subsequent to June thirtieth, nineteen hundred
      eighty-two.
        (iii)  The  annual  installments  to be credited, for 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, in respect of each present value  computed  in  accordance
      with  item  (ii) of this subparagraph (b) shall be an amount which, when
      credited  in  equal  annual  installments  commencing  with  the  city's
      nineteen  hundred  eighty-two--nineteen hundred eighty-three fiscal year
      and continuing for the number of fiscal years equal  to  the  number  of
      installments  used  in  computing  such  present  value,  would  be  the
      actuarial equivalent, as of June thirtieth, nineteen hundred  eighty-two
      on  the basis of eight per centum interest per annum, of an amount equal
      to such present value.
        (iv) (A) As used in this item (iv),  the  term  "remaining  uncredited
      installments  as  of  July  first,  nineteen hundred eighty-eight" shall
      mean, in relation to any gain referred  to  in  paragraph  two  of  this
      subdivision   c,  the  number  of  installments,  if  any,  obtained  by
      subtracting eight installments from the number of installments  computed
      pursuant  to  paragraph  five  of this subdivision c in relation to such
      gain.
        (B) There shall be computed, as of June  thirtieth,  nineteen  hundred
      eighty-eight,  using an interest rate of eight per centum per annum, the
      present value of the remaining uncredited installments as of July first,
      nineteen hundred eighty-eight, if any, with respect  to  any  such  gain
      referred to in paragraph two of this subdivision.
        (C)  The  annual installments to be credited with respect to such gain
      in each city fiscal year occurring during the period beginning  on  July
      first,  nineteen  hundred eighty-eight and ending with the last day of a
      number of fiscal years equal  to  the  number  of  remaining  uncredited
      installments  as  of  July  first,  nineteen  hundred  eighty-eight with
      respect to such gain, shall be an amount which, when credited  in  equal
      annual   installments,  commencing  with  the  city's  nineteen  hundred
      eighty-eight--nineteen hundred eighty-nine fiscal  year  and  continuing
      during  each  fiscal year of the period above mentioned in this sub-item
    
      (C), shall be the actuarial equivalent, as of June  thirtieth,  nineteen
      hundred  eighty-eight  on  the basis of eight and one-quarter per centum
      interest per annum, of such present value computed pursuant to  sub-item
      (B) of this item (iv).
        (7)  (a)  If  any  such  gain  referred  to  in  paragraph one of this
      subdivision c was realized in the city's nineteen hundred seventy-nine--
      nineteen hundred eighty fiscal year, the  amount  of  such  gain  shall,
      beginning  with the nineteen hundred eighty--nineteen hundred eighty-one
      fiscal year, be credited in favor of such responsible public employer in
      twenty successive equal annual installments  determined  in  the  manner
      provided for by subparagraphs (b), (c) and (d) of this paragraph seven.
        (b)   The   first  and  second  annual  installments  referred  to  in
      subparagraph (a) of this paragraph seven shall be determined so that  if
      they  were  the  first and second of twenty equal annual installments of
      the amount of such gain, the present value of such twenty  equal  annual
      installments,  computed  at  an  interest rate of seven and one-half per
      centum per annum, would be equal to the amount of such gain.
        (c) The next six annual installments required to be credited under the
      provisions  of  subparagraph  (a)  of  this  paragraph  seven  shall  be
      determined  so  as to be equal and so that the present value of such six
      equal annual installments,  computed  as  of  June  thirtieth,  nineteen
      hundred  eighty-two at an interest rate of eight per centum per annum as
      if they were part of a remainder of eighteen equal  annual  installments
      so  computed,  shall  be equal to the present value, computed as of such
      June thirtieth at an interest rate of seven and one-half per centum  per
      annum,  of  the  corresponding  next  six  of  the  twenty  equal annual
      installments computed pursuant to the provisions of subparagraph (b)  of
      this paragraph seven.
        (d)  The  remaining twelve annual installments required to be credited
      under the provisions of subparagraph (a) of this paragraph  seven  shall
      be  determined  so  as to be equal and so that the present value of such
      twelve  equal  annual  installments,  computed  as  of  June  thirtieth,
      nineteen   hundred  eighty-eight  at  an  interest  rate  of  eight  and
      one-quarter per centum per annum, shall be equal to the  present  value,
      computed  as  of  such  June  thirtieth at an interest rate of eight per
      centum per annum, of such last twelve equal annual installments.
        d. (1) If any such sale  occurring  in  the  city's  nineteen  hundred

      fiscal year up to and  including  the  nineteen  hundred  seventy-nine--
      nineteen  hundred  eighty fiscal year results in a loss, the responsible

      hundred  seventy fiscal year or in any subsequent city fiscal year up to

      seventy-nine  fiscal  year,  there shall be computed twenty equal annual
      installments of payment on account of such loss, the aggregate of  which
      installments,  if one of such installments were paid by such responsible
      public employer to the contingent reserve fund in  each  of  the  twenty
      city  fiscal years commencing with the second fiscal year succeeding the
      fiscal year  in  which  such  loss  occurred,  would  be  the  actuarial
      equivalent  of  the  amount of such loss. For the purpose of making such
      computation with respect to losses which occurred prior to  July  first,
      nineteen  hundred  seventy-five, an interest rate of four per centum per
      annum shall be used and for the purpose of making such computation  with
    
      respect  to  losses  which  occurred during the period beginning on July
      first, nineteen hundred  seventy-five  and  ending  on  June  thirtieth,

      subdivision d which was sustained in  any  city  fiscal  year  occurring
      during  the  period beginning on July first, nineteen hundred sixty-nine
      and ending on June thirtieth, nineteen  hundred  seventy-eight,  one  of
      such  installments  shall be paid by such responsible public employer to
      the contingent reserve fund of such retirement system in the second city
      fiscal year succeeding that in which such loss  was  sustained  and  one
      such installment shall be so paid by such responsible public employer in
      each  succeeding  fiscal  year  to  and  including  the nineteen hundred
      seventy-nine--nineteen hundred eighty fiscal year.
        (4) With  respect  to  each  loss  to  which  paragraph  two  of  this
      subdivision  d applies, there shall be computed the present value, as of
      June thirtieth, nineteen hundred eighty, of the annual  installments  of
      such  loss  remaining  unpaid  by such responsible public employer as of
      such June thirtieth. For the purpose  of  making  such  calculation,  an
      interest rate of five and one-half per centum per annum shall be used.
        (5)  With respect to each present value computed pursuant to paragraph
      four of this subdivision d, there shall be computed a  number  of  equal
      annual  installments  of  loss  to  be  paid  by such responsible public
      employer to the contingent reserve fund, which number  shall  equal  one
      less  than  the  number of the unpaid installments of such loss to which
      such  present  value  relates,  and  the  aggregate  of  which  computed
      installments,  on the basis of payment of the first of such installments
      by such responsible public  employer  in  the  city's  nineteen  hundred
      eighty--nineteen   hundred  eighty-one  fiscal  year  and  one  of  such
      installments  in  each  subsequent  fiscal  year  until  all   of   such
      installments are paid, shall be the actuarial equivalent of such present
      value.  For  the purpose of making such computation, an interest rate of
      seven and one-half per centum per annum shall be used.
        (6) (a) Such  responsible  public  employer  shall  pay  one  of  such
      installments  computed  pursuant to paragraph five of this subdivision d
      to the contingent reserve fund of such retirement system in each of  the

        (b)  (i)  Such  responsible  public employer, in 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,
      shall pay an installment computed in  accordance  with  items  (ii)  and
      (iii) of this subparagraph (b).
        (ii) With respect to each present value computed pursuant to paragraph
      four  of  this  subdivision  d,  there  shall  be  computed  as  of June
      thirtieth, nineteen hundred eighty-two, using an interest rate of  seven
      and  one-half  per  centum  per  annum,  the present value of the annual
      installments of loss determined in accordance  with  paragraph  five  of
      this  subdivision  d  and  allocated  to fiscal years subsequent to June
      thirtieth, nineteen hundred eighty-two.
        (iii) The annual installments of loss required  to  be  paid  by  such
      responsible  public employer, for 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, in respect of
      each present value  computed  in  accordance  with  item  (ii)  of  this
      subparagraph  (b)  shall  be  the  applicable  installments of an amount
      which, if paid in equal annual installments commencing with  the  city's
      nineteen  hundred  eighty-two--nineteen hundred eighty-three fiscal year
    
      and continuing for the number of fiscal years equal  to  the  number  of
      installments  used  in  computing  such  present  value,  would  be  the
      actuarial equivalent, as of June thirtieth, nineteen hundred  eighty-two
      on  the basis of eight per centum interest per annum, of an amount equal
      to such present value.
        (iv) (A) As used  in  this  item  (iv),  the  term  "remaining  unpaid
      installments  as  of  July  first,  nineteen hundred eighty-eight" shall

      subtracting eight installments from the number of installments  computed
      pursuant  to  paragraph  five  of this subdivision d in relation to such
      loss.
        (B) There shall be computed, as of June  thirtieth,  nineteen  hundred
      eighty-eight,  using an interest rate of eight per centum per annum, the
      present value of the remaining unpaid installments  as  of  July  first,
      nineteen  hundred  eighty-eight,  if  any, with respect to any such loss
      referred to in paragraph two of this subdivision.
        (C) The annual installments to be paid with respect to  such  loss  in
      each  city  fiscal  year  occurring  during the period beginning on July

      number  of  fiscal  years  equal  to  the  number  of  remaining  unpaid
      installments as  of  July  first,  nineteen  hundred  eighty-eight  with
      respect  to  such  loss,  shall  be  an amount which, when paid in equal
      annual  installments,  commencing  with  the  city's  nineteen   hundred
      eighty-eight--nineteen  hundred  eighty-nine  fiscal year and continuing
      during each fiscal year of the period above mentioned in  this  sub-item

      the  amount  of such loss, the present value of such twenty equal annual
      installments, computed at an interest rate of  seven  and  one-half  per
      centum per annum, would be equal to the amount of such loss.
        (c)  The  next  six  annual installments required to be paid under the

      determined  so  as  to  be  equal  and so that the present value of such
    
      twelve  equal  annual  installments,  computed  as  of  June  thirtieth,
      nineteen   hundred  eighty-eight  at  an  interest  rate  of  eight  and
      one-quarter per centum per annum, shall be equal to the  present  value,
      computed  as  of  such  June  thirtieth at an interest rate of eight per
      centum per annum, of such last twelve equal annual installments.
        e. (1) In the case of sales occurring in the city's  nineteen  hundred
      eighty--nineteen  hundred  eighty-one  fiscal  year or in any subsequent
      fiscal year ending before July first, nineteen hundred eighty-eight, the
      retirement system making such sales shall,  with  respect  to  any  such
      fiscal  year  above  specified  in  this  paragraph,  provide credit for
      realized gains and amortization of realized losses for each  responsible
      public  employer pursuant to the applicable provisions of paragraphs two
      and three of this subdivision e.
        (2) For each fiscal year to which paragraph one of this subdivision  e
      applies,  there  shall  be calculated for each retirement system the net
      amount of aggregate gains and aggregate losses produced by sales in such
      fiscal year and such net  amount  shall  be  transferred  to  a  special
      account  in the retirement system to be known as the "deferred charge on
      account of security sales". Such net amount for each  such  fiscal  year
      shall  be  amortized  within  such  account, commencing with such fiscal
      year, over the average maturity, rounded to the  nearest  year,  of  all
      securities  (excluding  securities  maturing  in  less  than  one  year)
      acquired in such fiscal  year  or  sold  in  such  fiscal  year  by  the
      retirement systems, whichever is less.
        (3)  The amount to be amortized in each fiscal year over the period of
      average maturity referred to in paragraph  two  of  this  subdivision  e
      shall  be  computed on a scientific basis, (a) using a reinvestment rate
      of seven and one-half per centum per annum with respect to any such  net
      amount computed for the city's nineteen hundred eighty--nineteen hundred
      eighty-one  fiscal  year, and (b) using a reinvestment rate of eight per
      centum per annum with respect to any such net amount  computed  for  any
      city  fiscal  year  occurring during the period beginning on July first,
      nineteen hundred eighty-one  and  ending  on  June  thirtieth,  nineteen
      hundred  eighty-four and (c) in the case of any such net amount computed
      for any city fiscal year occurring thereafter, using a reinvestment rate
      equivalent to that prescribed by the legislature as the rate to be  used
      for  the  purpose of any actuarial valuation, determination or appraisal
      made in determining the employer contributions to be paid by responsible
      public employers to the  contingent  reserve  fund  of  such  retirement
      system  in  the city fiscal year next succeeding that for which such net
      amount was computed.
        4. Any account constituting a deferred charge on account  of  security
      sales (whether a positive or negative quantity) which, in the absence of
      the  enactment  of a chapter of the laws of nineteen hundred eighty-nine
      which added this paragraph, would exist with respect to  any  retirement
      system  as  of  July  first,  nineteen  hundred  eighty-eight,  shall be
      cancelled and terminated as of such July first, and shall not be applied
      in  the  determination  of  the  normal  contribution   or   any   other
      contribution   payable  by  any  responsible  public  employer  to  such
      retirement system with respect to any fiscal year beginning on or  after
      such July first.
        e-1.  (1)  In  the case of sales by any retirement system occurring in
      any fiscal year of the city beginning on or after July  first,  nineteen
      hundred eighty-eight:
        (i)  any  gain  resulting from any such sale shall not be directly and
      separately credited against contributions otherwise required to be  made
      by  the  responsible  public  employer  or  employers to such retirement
      system; and
    
        (ii) any loss resulting from any such sale shall not be  directly  and
      separately   charged   as   additional  contributions  payable  to  such
      retirement system by the responsible public employer or employers; and
        (iii)  the  effects  of  such  gains  or  losses  shall be actuarially
      reflected  in  the  valuations  made  for  the  purpose  of  determining
      contributions payable to such retirement system.
        (2)  In  relation  to determination of the normal contribution for any
      fiscal  year  beginning  on  or  after  July  first,  nineteen   hundred
      eighty-eight, the provisions of sub-item (C) of item (i) of subparagraph
      (b) of paragraph two of subdivision b of section 13-127 of the code, and
      sub-item  (D)  of  item  (i)  of  subparagraph  (i)  of paragraph two of
      subdivision b of section 13-228 of the code, and sub-item  (E)  of  item
      (i)  of  subparagraph  (b)  of paragraph two of subdivision b of section
      13-331 of the code, and item (iii) of subparagraph (a) of paragraph  two
      of  subdivision  b  of section 13-527 of the code, or paragraph three of
      sub-item (A) of item (ii) of  subparagraph  four  of  paragraph  (c)  of
      subdivision  sixteen  of section twenty-five hundred seventy-five of the
      education law (relating to the actuarial treatment of certain losses  on
      sales  of  fixed-income  securities  in  the determination of the normal
      contribution) shall not be deemed to refer to or include  any  gains  or
      losses  on  any  such  sales  occurring  in  any fiscal year of the city
      beginning on or after July first, nineteen hundred eighty-eight.
        f. The provisions  of  section  one  hundred  seventy-seven-b  of  the
      retirement  and  social  security  law shall be inapplicable to any sale
      described in subdivisions b and e-1 of this section.
        g. Nothing contained in this section shall be construed as  applicable
      to  any  sale  of  securities constituting an investment made with funds
      which are a  part  of  a  variable  annuity  program  in  the  teachers'
      retirement  system  or  the  board of education retirement system of the
      city.
        h. (1) For the purpose of determining the balance sheet  liability  of
      any  retirement  system  as  of  June thirtieth, nineteen hundred eighty
      pursuant to  the  provisions  of  the  retirement  system  act  of  such
      retirement    system   governing   such   determination,   the   "annual
      contribution, for  balance  sheet  liability  purposes,  on  account  of
      amortization  of losses on dispositions of certain securities within the
      meaning of this section", as referred to in such provisions, shall be  a
      hypothetical  amount  computed  pursuant to the provisions of paragraphs
      two to four, inclusive, of this subdivision g.
        (2) With respect to each city fiscal year (the "subject fiscal  year")
      occurring  during  the  period beginning on July first, nineteen hundred
      seventy-four and ending on  June  thirtieth,  nineteen  hundred  eighty,
      there shall be determined the amount by which:
        (i)  The  total  of the annual installments of losses which, under the
      provisions of this section as in effect prior to  July  first,  nineteen
      hundred eighty, was or would have been payable by the responsible public
      employer  in  the  second city fiscal year succeeding the subject fiscal
      year, exceeds
        (ii) The total of the installments of gain required by such provisions
      of this section as they are in effect to be credited to the  responsible
      public employer in such second fiscal year.
        (3)  (i) There shall be computed the discounted value of the amount of
      such excess as of  January  first  of  the  subject  fiscal  year,  such
      discounting  being  calculated  on  the basis of the applicable interest
      rate prescribed in subparagraph (ii)  of  this  paragraph  three  and  a
      discount  period  of  two  years  extending  retroactively from December
      thirty-first of such second fiscal year succeeding  the  subject  fiscal
      year to January first of the subject fiscal year.
    
        (ii)  With  respect  to  the  nineteen  hundred seventy-four--nineteen
      hundred seventy-five subject fiscal year, the rate  of  interest  to  be
      used in calculating such discounted value shall be five and one-half per
      centum  per  annum  for  the  period  beginning  on July first, nineteen
      hundred  seventy-five  and  ending  on  December  thirty-first, nineteen
      hundred seventy-six and  four  per  centum  per  annum  for  the  period
      beginning  on January first, nineteen hundred seventy-five and ending on
      June thirtieth, nineteen hundred  seventy-five.  With  respect  to  each
      subject fiscal year occurring during the period beginning on July first,
      nineteen  hundred  seventy-five  and  ending on June thirtieth, nineteen
      hundred eighty, the rate of interest used in calculating such discounted
      value shall be five and one-half per centum per annum.
        (4) The amount of such discounted value, as so computed  with  respect
      to  each  subject  fiscal  year,  shall  be the annual contribution, for
      balance sheet liability purposes, on account of amortization  of  losses
      on  dispositions  of  certain  securities  within  the  meaning  of this
      section, which annual contribution is deemed to have been hypothetically
      payable in such subject fiscal year.
