Over 30 years of retirement, Isermann would collect as much as $4.18 million, according to a projection by Local Government Information Services (LGIS), which publishes Illinois Valley Times.
The projection assumes Isermann received $87,900 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Isermann will have already received $178,437 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
