Over 30 years of retirement, Dunigan would collect as much as $1.75 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Dunigan received $36,869 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Dunigan will have already received $74,844 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
