Beginning January 1, 2016, the $800 ($1,000 for portions of the annuity based on service as a noncovered employee) referred in item (2) of this subsection (d) shall be increased on each January 1 by the annual unadjusted percentage increase (but not less than zero) in the consumer price index-u for the 12 months ending with the preceding September; these adjustments shall be cumulative and compounded. 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 dollar amount resulting from each annual adjustment shall be determined by the Public Pension Division of the Department of Insurance and made available to the System by November 1 of each year.
This subsection (d) is applicable without regard to whether the person is in service on or after the effective date of this amendatory Act of the 98th General Assembly.
