(a) Any person receiving a retirement annuity under this Article who retires having attained age 60, or who retires before age 60 having at least 35 years of creditable service, or who retires on or after January 1, 2001 at an age which, when added to the number of years of his or her creditable service, equals at least 85, shall, on January 1 next following the first full year of retirement, have the amount of the then fixed and payable monthly retirement annuity increased 3%. Any person receiving a retirement annuity under this Article who retires before attainment of age 60 and with less than (i) 35 years of creditable service if retirement is before January 1, 2001, or (ii) the number of years of creditable service which, when added to the member's age, would equal 85, if retirement is on or after January 1, 2001, shall have the amount of the fixed and payable retirement annuity increased by 3% on the January 1 occurring on or next following (1) attainment of age 60, or (2) the first anniversary of retirement, whichever occurs later. However, for persons who receive the alternative retirement annuity under Section 14-110, references in this subsection (a) to attainment of age 60 shall be deemed to refer to attainment of age 55. For a person receiving early retirement incentives under Section 14-108.3 whose retirement annuity began after January 1, 1992 pursuant to an extension granted under subsection (e) of that Section, the first anniversary of retirement shall be deemed to be January 1, 1993. For a person who retires on or after June 28, 2001 and on or before October 1, 2001, and whose retirement annuity is calculated, in whole or in part, under Section 14-110 or subsection (g) or (h) of Section 14-108, the first anniversary of retirement shall be deemed to be January 1, 2002. On each January 1 following the date of the initial increase under this subsection, the employee's monthly retirement annuity shall be increased by an additional 3%.
Beginning January 1, 1990, all automatic annual increases payable under this Section shall be calculated as a percentage of the total annuity payable at the time of the increase, including previous increases granted under this Article.
