Over 30 years of retirement, Osborne would collect as much as $2.51 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Osborne received $52,787 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Osborne will have already received $163,160 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
