Benefits Fact Sheet

Investments Fact Sheet


ACERA was established by the Alameda County Board of Supervisors under Ordinance No. 446, dated October 21, 1947.  On January 1, 1948, ACERA became operative to provide retirement, disability, and death benefits to the General and Safety members employed by Alameda County.

Defined Benefit Plan

ACERA’s plan is a defined benefit pension plan, qualified under Section 401(a) of the Internal Revenue Code.  Funding of a defined benefit pension plan is based on a cost sharing principle through employee and employer contributions rates, which are determined annually upon recommendation by the plan’s actuary.  Therefore, retirement benefits are determined by a formula and not on an individual’s account balance.

Plan Administration

ACERA’s Board of Retirement is responsible for establishing policies governing the administration of the retirement plan and managing the investments of the system’s assets. The Board has nine members and two alternate members. The Alameda County Board of Supervisors appoints four members and six are elected by ACERA’s membership. The County Treasurer is an ex-officio member.

The Board of Retirement oversees the Chief Executive Officer and staff in the performance of their duties in accordance with the County Employees Retirement Law of 1937, ACERA’s by-laws, and Board policies.


ACERA is a separate public entity governed by the provisions of the County Employees Retirement Law of 1937 (CERL), Title 3, Division 4, Chapter 3, commencing with Section 31450 of the California Government Code and case law applicable to public employee pension plans. The CERL, as amended, beginning at California Government Code Section 31450, et seq., is a body of law enacted to govern retirement benefits for certain public employees. The CERL governs retirement systems for county and district employees in those counties adopting its provisions pursuant to Cal. Gov. Code §31500. Twenty California counties operate retirement systems under the provisions of the 1937 Act, which sets forth the policies and regulations governing the actions of these county retirement systems.
