The Central States Pension Fund is a "defined benefit plan." Under a defined benefit plan, eligible participants receive a benefit at retirement. The benefit is calculated by a set formula, based on your contribution level, your age and your length of participation in the Fund.
To become a participant of the Pension Fund you need either 20 weeks or 75 days or 600 hours of employer contributions submitted to the Fund on your behalf in a 12-month period.
In general, once you have participated in the Pension Fund for five years you are a Vested Participant and have earned the right to receive a monthly benefit upon retirement at age 65. If you left the Fund before 1999 you need 10 years.
