Beginning January 1, 2023 and each year thereafter, the retirement allowance of each beneficiary of the System who is in receipt of a retirement allowance and who meets the eligibility criteria set forth in this section shall be adjusted by the amount described in subsection (d) of this section. In no event shall a beneficiary receive a negative adjustment to the beneficiary's retirement allowance.(b) Calculation of net percentage increase.(1) Consumer Price Index; maximum and minimum amounts. Prior to October 1 of each year, a determination shall be made of any increase or decrease, to the nearest one-tenth of a percent, in the Consumer Price Index for the month ending on June 30 of that year to the average of said index for the month ending on June 30 of the previous year. Any increase or decrease in the Consumer Price Index shall be subject to adjustment so as to remain within the following maximum and minimum amounts:(A) For Group A members, the maximum amount of any increase or decrease used to determine the net percentage increase shall be five percent.(B) For Group C members who are first eligible for normal retirement or unreduced early retirement on or before June 30, 2022, or who are vested deferred members as of June 30, 2022, the maximum amount of any increase or decrease used to determine the net percentage increase shall be five percent.(C) For Group C members who are first eligible for normal retirement or unreduced early retirement on or after July 1, 2022, the maximum amount of any increase or decrease used to determine the net percentage increase shall be four percent.(D) For Group D members, the maximum amount of any increase or decrease used to determine the net percentage increase shall be five percent.(E) For Group F and Group G members who are first eligible for normal retirement or unreduced early retirement on or before June 30, 2022, or who are vested deferred members as of June 30, 2022, the maximum amount of any increase or decrease used to determine the net percentage increase shall be five percent. In the event that there is an increase or decrease of less than one percent, the net percentage increase shall be assigned a value of one percent and shall not be subject to further adjustment pursuant to subsection (d) of this section.(F) For Group F and Group G members who are first eligible for normal retirement or unreduced early retirement on or after July 1, 2022, the maximum amount of any increase or decrease used to determine the net percentage increase shall be four percent.(2) Consumer Price Index; decreases. In the event of a decrease in the Consumer Price Index, there shall be no adjustment to retirement allowances for the subsequent year beginning January 1; provided, however, that:(A) such decrease shall be applied as an offset against the first subsequent year's increase of the Consumer Price Index, up to the full amount of such increase; and(B) to the extent that such decrease is greater than such subsequent year's increase, such decrease shall be offset in the same manner against two or more years of such increases, for up to but not exceeding five subsequent years of such increases, until fully offset.(3) Consumer Price Index; increases. In the event of an increase in the Consumer Price Index, and provided there remains an increase following the application of any offset as in subdivision (2) of this subsection, that amount shall be identified as the net percentage increase and used to determine the members' postretirement adjustment as described herein.(c) Eligibility for postretirement adjustment.
