 (from Ch. 108 1/2, par. 15-111)Sec. 15-111. Earnings.(a) "Earnings": Subject to Section 15-111.5, an amount paid for personal services equal to the sum of  the basic compensation plus extra compensation for summer teaching,  overtime or other extra service.  For periods for which an employee receives  service credit under subsection (c) of Section 15-113.1 or Section 15-113.2,  earnings are equal to the basic compensation on which contributions are  paid by the employee during such periods.  Compensation for employment which is  irregular, intermittent and temporary shall not be considered earnings, unless  the participant is also receiving earnings from the employer as an employee  under Section 15-107.With respect to transition pay paid by the University of Illinois to a  person who was a participating employee employed in the fire department of  the University of Illinois's Champaign-Urbana campus immediately prior to  the elimination of that fire department:(1) "Earnings" includes transition pay paid to the     employee on or after the effective date of this amendatory Act of the 91st General Assembly.(2) "Earnings" includes transition pay paid to the     employee before the effective date of this amendatory Act of the 91st General Assembly only if (i) employee contributions under Section 15-157 have been withheld from that transition pay or (ii) the employee pays to the System before January 1, 2001 an amount representing employee contributions under Section 15-157 on that transition pay.  Employee contributions under item (ii) may be paid in a lump sum, by withholding from additional transition pay accruing before January 1, 2001, or in any other manner approved by the System.  Upon payment of the employee contributions on transition pay, the corresponding employer contributions become an obligation of the State.(b) For a Tier 2 member, the annual earnings shall not exceed $106,800; however, that amount shall annually thereafter be increased by the lesser of (i) 3% of that amount, including all previous adjustments, or (ii) 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, including all previous adjustments.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. 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 retirement systems and pension funds by November 1 of each year.(c) With each submission of payroll information in the manner prescribed by the System, the  employer shall certify that the payroll information is correct and complies with all applicable  State and federal laws.(Source: P.A. 98-92, eff. 7-16-13; 99-897, eff. 1-1-17.)
