Over 30 years of retirement, O'Brien would collect as much as $1.15 million, according to a projection by Local Government Information Services (LGIS), which publishes Rockford Sun.
The projection assumes O'Brien received $24,130 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, O'Brien will have already received $100,952 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
