Other Post-Employment Benefits (OPEB) refer to the benefits, other than pension distributions, that some employers provide to retirees. These benefits can include life insurance, health insurance, and deferred compensation. In California, OPEB is the method by which the State of California, as the employer, and its employees jointly prefund health benefits that current active employees will receive as state retirees. All employees in positions that are eligible for health benefits, whether or not currently enrolled, prefund OPEB, and the state prefunds a matching contribution. OPEB contributions are deposited in the California Employers Benefit Trust (CERBT), which is an Internal Revenue Code, Section 115 Trust fund dedicated to prefunding OPEB for all eligible California public agencies, with the State of California being one of the participating employers. OPEB contributions are deducted from the total pensionable compensation of each pay period. The deduction is between 1% to 4% of an employees pay based on the bargaining unit, with matching employer contributions. Retired state employees do not prefund OPEB.
