Over 30 years of retirement, O'Brien would collect as much as $1.21 million, according to a projection by Local Government Information Services (LGIS), which publishes DuPage Policy Journal.
The projection assumes O'Brien received $25,344 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, O'Brien will have already received $106,029 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
