Over 30 years of retirement, Gibbons would collect as much as $407,626, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Gibbons received $8,568 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Gibbons will have already received $35,846 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
