The changes made to this subsection (a) by this amendatory Act of the 91st General Assembly apply to all pensions that become payable under this subsection on or after January 1, 1999. All pensions payable under this subsection that began on or after January 1, 1999 and before the effective date of this amendatory Act shall be recalculated, and the amount of the increase accruing for that period shall be payable to the pensioner in a lump sum.
A police officer who retires or is separated from service having at least 8 years but less than 20 years of creditable service, who is not mandatorily retired due to age by operation of law, and who does not apply for a refund of contributions at his or her last separation from police service, shall receive a pension upon attaining age 60 equal to 2.5% of the salary attached to the rank held by the police officer on the police force for one year immediately prior to retirement or, beginning July 1, 1987 for persons terminating service on or after that date, the salary attached to the rank held on the last day of service or for one year prior to the last day, whichever is greater, for each year of creditable service.
In order to be eligible for a pension under this subsection (c), the police officer must have at least 8 years of creditable service in a second police pension fund under this Article and be receiving a pension under subsection (a) or (b) of this Section from that second fund. The police officer need not be in service on or after the effective date of this amendatory Act of 1997.
A police officer age 55 or more who has 10 or more years of service in that capacity shall be entitled at his option to receive a monthly pension for his service as a police officer computed by multiplying 2.5% for each year of such service by his or her final average salary.
The pension of a police officer who is retiring after attaining age 50 with 10 or more years of creditable service shall be reduced by one-half of 1% for each month that the police officer's age is under age 55.
The maximum pension under this subsection (d) shall be 75% of final average salary.
For the purposes of this subsection (d), "final average salary" means the greater of: (i) the average monthly salary obtained by dividing the total salary of the police officer during the 48 consecutive months of service within the last 60 months of service in which the total salary was the highest by the number of months of service in that period; or (ii) the average monthly salary obtained by dividing the total salary of the police officer during the 96 consecutive months of service within the last 120 months of service in which the total salary was the highest by the number of months of service in that period.
Beginning on January 1, 2011, for all purposes under this Code (including without limitation the calculation of benefits and employee contributions), the annual salary based on the plan year of a member or participant to whom this Section applies 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) 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.
Nothing in this amendatory Act of the 101st General Assembly shall cause or otherwise result in any retroactive adjustment of any employee contributions.
