Over 30 years of retirement, Pemberton would collect as much as $2.68 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Pemberton received $56,313 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 5 years of retirement, Pemberton will have already received $298,971 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
