CalPERS
CalOptima is part of the California Public Employees’ Retirement System (CalPERS). Instead of participating in Social Security, CalOptima employees contribute a percentage of their pre-tax earnings to their CalPERS account. CalOptima also contributes the same percentage of the employee’s regular earnings into this account. This is a defined benefit retirement plan based on the employee’s years of service, final/highest compensation and age at retirement. Regular, full-time employees become vested in the plan after five years of service.
