Any sheriff's law enforcement employee who has 20 or more years of service in that capacity and who terminates service prior to January 1, 1988 shall be entitled at his option to receive a monthly retirement annuity for his service as a sheriff's law enforcement employee computed by multiplying 2% for each year of such service up to 10 years, 2 1/4% for each year of such service above 10 years and up to 20 years, and 2 1/2% for each year of such service above 20 years, by his annual final rate of earnings and dividing by 12.
Any sheriff's law enforcement employee who has 20 or more years of service in that capacity and who terminates service on or after January 1, 1988 and before July 1, 2004 shall be entitled at his option to receive a monthly retirement annuity for his service as a sheriff's law enforcement employee computed by multiplying 2.5% for each year of such service up to 20 years, 2% for each year of such service above 20 years and up to 30 years, and 1% for each year of such service above 30 years, by his annual final rate of earnings and dividing by 12.
Any sheriff's law enforcement employee who has 20 or more years of service in that capacity and who terminates service on or after July 1, 2004 shall be entitled at his or her option to receive a monthly retirement annuity for service as a sheriff's law enforcement employee computed by multiplying 2.5% for each year of such service by his annual final rate of earnings and dividing by 12.
If a sheriff's law enforcement employee has service in any other capacity, his retirement annuity for service as a sheriff's law enforcement employee may be computed under this Section and the retirement annuity for his other service under Section 7-142.
In no case shall the total monthly retirement annuity for persons who retire before July 1, 2004 exceed 75% of the monthly final rate of earnings. In no case shall the total monthly retirement annuity for persons who retire on or after July 1, 2004 exceed 80% of the monthly final rate of earnings.
A sheriff's law enforcement employee 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 retirement annuity for his or her service as a sheriff's law enforcement employee computed by multiplying 2.5% for each year of such service by his or her final rate of earnings.
The retirement annuity of a sheriff's law enforcement employee 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 sheriff's law enforcement employee's age is under age 55.
The maximum retirement annuity under this subsection (f) shall be 75% of final rate of earnings.
For the purposes of this subsection (f), "final rate of earnings" means the average monthly earnings obtained by dividing the total salary of the sheriff's law enforcement employee during the 96 consecutive months of service within the last 120 months of service in which the total earnings was the highest by the number of months of service in that period.
Notwithstanding any other provision of this Article, beginning on January 1, 2011, for all purposes under this Code (including without limitation the calculation of benefits and employee contributions), the annual earnings of a sheriff's law enforcement employee to whom this Section applies shall not include overtime and 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.
