    (Text of Section WITH the changes made by P.A. 98-641, which has been held unconstitutional)
    Sec. 8-137.1. Automatic increases in annuity for certain heretofore retired participants.
    (a) A retired municipal employee who (i) is receiving annuity based on a service credit of 20 or more years regardless of age at retirement or based on a service credit of 15 or more years with retirement at age 55 or over, and (ii) does not qualify for the automatic increases in annuity provided for in Section 8-137 of this Article, and (iii) elects to make a contribution to the Fund at a time and manner prescribed by the Retirement Board, of a sum equal to 1% of the amount of final monthly salary times the number of full years of service on which the annuity was based in those cases where the annuity was computed on the money purchase formula and in those cases in which the annuity was computed under the minimum annuity formula provisions of this Article a sum equal to 1% of the average monthly salary on which the annuity was based times such number of full years of service, shall have his original fixed and payable monthly amount of annuity increased in January of the year following the year in which he attains the age of 65 years, if such age of 65 years is attained in the year 1969 or later, by an amount equal to 1-1/2%, and by an equal additional 1-1/2% in January of each year thereafter. Beginning with January of the year 1972, such increases shall be at the rate of 2% in lieu of the aforesaid specified 1 1/2%, and beginning January of the year 1984 such increases shall be at the rate of 3%. Beginning in January of 1999, such increases shall be at the rate of 3% of the currently payable monthly annuity, including any increases previously granted under this Article.
    Whenever the retired municipal employee receiving annuity has attained the age of 66 or more in 1969, he shall have such annuity increased in January, 1970 by an amount equal to 1-1/2% multiplied by the number equal to the number of months of January elapsing from and including January of the year immediately following the year he attained the age of 65 if retired at or before age 65, or from and including January of the year immediately following the year of retirement if retired at an age greater than 65, to and including January, 1970, and by an equal additional 1-1/2% in January of each year thereafter. Beginning with January of the year 1972, such increases shall be at the rate of 2% in lieu of the aforesaid specified 1 1/2%, and beginning January of the year 1984 such increases shall be at the rate of 3%. Beginning in January of 1999, such increases shall be at the rate of 3% of the currently payable monthly annuity, including any increases previously granted under this Article.
    (b) To defray the annual cost of such increases, the annual interest income of the Fund, accruing from investments held by the Fund, exclusive of gains or losses on sales or exchanges of assets during the year, over and above 4% a year, shall be used to the extent necessary and available to finance the cost of such increases for the following year, and such amount shall be transferred as of the end of each year, beginning with the year 1969, to a Fund account designated as the Supplementary Payment Reserve from the Investment and Interest Reserve set forth in Section 8-221. The sums contributed by annuitants as provided for in this Section shall also be placed in the aforesaid Supplementary Payment Reserve and shall be applied and used for the purposes of such Fund account, together with the aforesaid interest.
    In the event the monies in the Supplementary Payment Reserve in any year arising from: (1) the available interest income as defined hereinbefore and accruing in the preceding year above 4% a year and (2) the contributions by retired persons, as set forth hereinbefore, are insufficient to make the total payments to all persons estimated to be entitled to the annuity increases specified hereinbefore, then (3) any interest earnings over 4% a year beginning with the year 1969 which were not previously used to finance such increases and which were transferred to the Prior Service Annuity Reserve may be used to the extent necessary and available to provide sufficient funds to finance such increases for the current year, and such sums shall be transferred from the Prior Service Annuity Reserve.
    In the event the total monies available in the Supplementary Payment Reserve from the preceding indicated sources are insufficient to make the total payments to all persons entitled to such increases for the year, a proportionate amount computed as the ratio of the monies available to the total of the total payments for that year shall be paid to each person for that year.
    The Fund shall be obligated for the payment of the increases in annuity as provided for in this Section only to the extent that the assets for such purpose, as specified herein, are available.
    (b-5) Notwithstanding any provision of this Section to the contrary:
        (1) Except for persons eligible under subdivision (3)
    
of this subsection for a minimum annual increase, there shall be no annual increase under this Section in years 2017, 2019, and 2025.
        (2) In all other years, beginning January 1, 2015,
    
the Fund shall pay an annual increase to persons eligible to receive one under this Section, in lieu of any other annual increase provided under this Section (but subject to the minimum increase under subdivision (3) of this subsection, if applicable) in an amount equal to the lesser of 3% or one-half the annual unadjusted percentage increase (but not less than zero) in the consumer price index-u for the 12 months ending with the September preceding each November 1 of the person's last annual annuity amount prior to January 1, 2015.
        For the purposes of this Section, "consumer price
    
index-u" means the index published by the Bureau of Labor Statistics of the United States Department of Labor that measures the average change in prices of goods and services purchased by all urban consumers, United States city average, all items, 1982-84 = 100.
        (3) A person is eligible under this subdivision (3)
    
to receive a minimum annual increase in a particular year if: (i) the person is otherwise eligible to receive an annual increase under subdivision (2) of this subsection, and (ii) the annual amount of the annuity payable at the time of the increase, including all increases previously received, is less than $22,000.
        Beginning January 1, 2015, for a person who is
    
eligible under this subdivision (3) to receive a minimum annual increase in the year 2017, 2019, or 2025, the annual increase shall be 1% of the person's last annual annuity amount prior to January 1, 2015.
        Beginning January 1, 2015, for any other year in
    
which a person is eligible under this subdivision (3) to receive a minimum annual increase, the annual increase shall be as specified under subdivision (2), but not less than 1% of the person's last annual annuity amount prior to January 1, 2015.
    For the purposes of Section 1-103.1, this subsection (b-5) is applicable without regard to whether the employee was in active service on or after the effective date of this amendatory Act of the 98th General Assembly. This subsection (b-5) applies to any former employee who on or after the effective date of this amendatory Act of the 98th General Assembly is receiving a retirement annuity and is eligible for an automatic annual increase under this Section.
