Section 13-646. Computation of supplemental pensions

1. Subject to the
  filing of verified applications for such  payments  by  person  entitled
  thereto,  the  monthly supplemental pension to be paid to a city retired
  employee shall be computed by
    (a) Multiplying by forty (or forty-three  and  two-fifths  in  a  case
  where  a  retired employee may receive a maximum retirement allowance or
  pension, computed without optional modification, of thirteen hundred two
  dollars) the number of years not  exceeding  thirty,  of  allowable  and
  credited  service on which his or her retirement allowance or pension is
  based,
    (b) subtracting therefrom the amount of his or her  annual  retirement
  allowance or pension, computed without optional modification, and
    (c) dividing the result so obtained by twelve.
    2.  In  no event shall the monthly supplemental pension paid to a city
  retired employee exceed
    (a) twenty-five dollars, or thirty-three dollars and  fifty  cents  in
  any  case  where  the maximum under paragraph (b) of this subdivision is
  one hundred eight dollars and fifty cents, or
    (b) an amount which when added to an amount equal  to  one-twelfth  of
  his  or  her  annual  retirement  allowance or pension, computed without
  optional modification, exceeds the sum of one hundred  dollars,  or  one
  hundred eight dollars and fifty cents.
    (1)  in  the  case  of  a retired employee who attained age sixty-five
  before April first, nineteen hundred fifty-six or who attains  such  age
  on  or  after  such  date,  beginning with April first, nineteen hundred
  fifty-six or with the first of the month following the date such retired
  employee attains the age of sixty-five years;
    (2) in the case of a retired female person who attained age  sixty-two
  before April first, nineteen hundred fifty-seven or who attains such age
  on  or  after  such  date,  beginning with April first, nineteen hundred
  fifty-seven or with the first of  the  month  following  the  date  such
  retired employee attains the age of sixty-two years; and
    (3)  in  the case of a person retired for disability, either before or
  after attaining age fifty, who attained such  age  before  April  first,
  nineteen  hundred  fifty-seven, or who attains such age on or after such
  date, beginning with April first, nineteen hundred fifty-seven, or  with
  the  first of the month following the date such retired employee attains
  the age of fifty years.
    3. For the purposes of this section,  in  determining  the  number  of
  years  of allowable and credited service, a major fraction or decimal of
  a year shall be counted as a full year.
    4. If any salary or time adjustment is pending then  the  supplemental
  pension  payments  to  be  received  by a city retired employee shall be
  regarded as payments on account of any increase in pension or retirement
  allowance to which such city retired employee  may  become  entitled  by
  reason  of  such  salary  or time adjustment, and may be offset from any
  increased pension payment or retired allowance which may become  payable
  to such city retired employee by reason of such adjustment.
    5. Notwithstanding any other provision of this article.
    (a)  any  person who was retired prior to July first, nineteen hundred
  sixty and who as a result  of  such  retirement  receives  a  retirement
  allowance or pension from the New York city teachers' retirement system,

  fifty-six, or who attains such age on or after  such  date  and  who  is
  receiving  or  is entitled to receive a supplemental pension pursuant to
  this article on or after such date shall, beginning with  the  month  of
  April, nineteen hundred fifty-six, if he or she is then sixty-five years
  of  age  or  beginning  with the month thereafter during which he or she

  amount  which  when  added to his or her monthly retirement allowance or
  pension, computed without optional modification, shall be equal  to  one
  hundred eight dollars fifty cents;
    (b)  in  the  case of any female person meeting such requirements, who
