Over 30 years of retirement, Lau would collect as much as $470,574, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Lau received $9,891 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 1 years of retirement, Lau will have already received $9,891 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
