California CLASS Investment Options

What is California CLASS?

The California Cooperative Liquid Assets Securities System (California CLASS) is a joint exercise of powers entity authorized under Section 6509.7, California Government Code. California CLASS is a pooled investment option that was created via a joint exercise of powers agreement by and among California public agencies. California CLASS provides California public agencies with a convenient method for investing in high-quality, short- to medium-term securities carefully selected to optimize interest earnings while prioritizing safety and liquidity. The California CLASS Prime and Enhanced Cash funds offer public agencies the opportunity to strengthen and diversify their cash management programs in accordance with the safety, liquidity, and yield hierarchy that governs the investment of public funds.

California CLASS strives to minimize risk by managing its portfolios in a manner that prioritizes principal preservation and only invests in securities that are permitted pursuant to the laws of the state of California and the  California CLASS Investment Policies.

The management of California CLASS is under the direction of a Board of Trustees comprised of eligible Participants of the program. The Board of Trustees has appointed Public Trust Advisors, LLC to serve as the Investment Advisor and Administrator of the program and has appointed U.S. Bank as the Custodian.
