Public Risk Innovation, Solutions, and Management: PRISM





PRISM is a member directed risk sharing pool.

New name, continued commitment

We have spent 40 years as CSAC Excess Insurance Authority, developing effective risk management solutions to help public entities proactively control losses and prepare for property, casualty and employee benefit exposures. As PRISM, we will continue this commitment to Innovation, Solutions, and Management of risk.

Members, staff, and our long term partner Alliant Insurance Services, Inc., have worked together to provide you with access to risk coverage programs that are stable, secure, and flexible.

The History of PRISM

In 1979, 29 California counties formed CSAC Excess Insurance Authority, a Joint Powers Authority, pursuant to Article 1, Chapter 5, Division 7, Title 1, of the California Government Code (Section 6500 et seq.). The sole purpose of this new JPA was to find cost-effective insurance solutions and risk management services for members.

In 2020, the EIA became Public Risk Innovation, Solutions, and Management. PRISM’s successful approach to insurance has been noticed across the state of California. Membership has expanded to include 95% of counties, 70% of cities, as well as educational organizations, special districts, housing authorities, fire districts, and 27 other Joint Powers Authorities. In 2019, the Board of Directors approved expanding outside of California. Growing nationally is one example of the innovative spirit PRISM embodies.


PRISM has been accredited with excellence continuously since 1989 by the California Association of Joint Powers Authority (CAJPA) and was the first JPA in California to receive the Government Finance Officers Association’s Certificate of Excellence in Financial Reporting in 1994. Member involvement has made PRISM one of the largest property, casualty and employee benefit public entity risk pools in the nation and helped to make PRISM a pioneer in the JPA risk management community.
