(2) The limitation of the maximum retirement allowance provided in subsection 
(a) of this section shall not be applicable to increases under this subsection.
      (c) Each retired member of fund B shall have his allowance increased to the 
amount which would be payable based on his annual rate of pay for the three highest-paid years of service.
      (d) For purposes of determining eligibility for retirement benefits for part-time 
employees under this section, a member's part-time service shall be payable to a 
member whose service consists solely of part-time service without variation in the 
number of hours worked during all periods of his municipal service, such member's 
service shall be treated as full-time service. For purposes of computing the retirement 
benefit payable to a member whose service consists of part-time and full-time service 
or whose service consists of part-time service rendered in different proportions to 
a full-time schedule, such member's years of service and average salary shall be 
proportionately adjusted to produce a retirement benefit equivalent to that payable if 
his service had been rendered at an unvarying rate. As used in this subsection, "part-time service" means service by a member who customarily works less than a full-time schedule but no less than twenty hours per week.
      (e) On and after January 1, 2002, the following formula shall be used for the 
purpose of calculating the monthly allowance of each member covered by the Old 
Age and Survivors Insurance System on the first of the month after such member 
becomes eligible for Social Security or until such member qualifies for a Social 
Security disability award, if earlier: One-twelfth of one and one-half per cent of such 
member's final average pay up to the breakpoint for the year in which such member 
separated from service plus two per cent of such member's final average pay in 
excess of the breakpoint for the year in which such member separated from service, 
multiplied by such member's years of retirement credit and fractions thereof. Such 
allowance shall be reduced in recognition of any optional form of retirement income 
elected in accordance with section 7-439g. For the purposes of this subsection, 
"breakpoint" has the same meaning as "year's breakpoint" in subsection (a) of section 
5-192f.
