    (b) Subsection (a) of this Section is not applicable to an employee receiving a term annuity.
    (c) To help defray the cost of such increases in annuity, there shall be deducted, beginning September 1, 1967, from each payment of salary to a policeman, 1/2 of 1% of each salary payment concurrently with and in addition to the salary deductions otherwise made for annuity purposes.
    The city, in addition to the contributions otherwise made by it for annuity purposes under other provisions of this Article, shall make matching contributions concurrently with such salary deductions.
    Each such 1/2 of 1% deduction from salary and each such contribution by the city of 1/2 of 1% of salary shall be credited to the Automatic Increase Reserve, to be used to defray the cost of the annuity increase provided by this Section. Any balance in such reserve as of the beginning of each calendar year shall be credited with interest at the rate of 3% per annum.
    Such deductions from salary and city contributions shall continue while the policeman is in service.
    The salary deductions provided in this Section are not subject to refund, except to the policeman himself, in any case in which: (i) the policeman withdraws prior to qualification for minimum annuity or Tier 2 monthly retirement annuity and applies for refund, (ii) the policeman applies for an annuity of a type that is not subject to annual increases under this Section, or (iii) a term annuity becomes payable. In such cases, the total of such salary deductions shall be refunded to the policeman, without interest, and charged to the Automatic Increase Reserve.
    (d) Notwithstanding any other provision of this Article, the Tier 2 monthly retirement annuity of a person who first becomes a policeman under this Article on or after the effective date of this amendatory Act of the 97th General Assembly shall be increased on the January 1 occurring either on or after (i) the attainment of age 60 or (ii) the first anniversary of the annuity start date, whichever is later. Each annual increase shall be calculated at 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, whichever is less, of the originally granted retirement annuity. If the annual unadjusted percentage change in the consumer price index-u for a 12-month period ending in September is zero or, when compared with the preceding period, decreases, then the annuity shall not be increased.
    For the purposes of this subsection (d), "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. The new amount resulting from each annual adjustment shall be determined by the Public Pension Division of the Department of Insurance and made available to the boards of the pension funds by November 1 of each year.
