Over 30 years of retirement, Walls would collect as much as $459,253, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Walls received $9,653 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Walls will have already received $40,385 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
