Over 30 years of retirement, Thomson would collect as much as $901,624, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Thomson received $18,951 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Thomson will have already received $79,286 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
