BACKGROUND:
Government Code Section 53646 requires the County Treasurer to prepare quarterly reports to the Board of Supervisors describing County investments including type, par value, cost, and market value. Attached please find the report covering the period October 1, 2025 through December 31, 2025.
As of December 31, 2025, the par value, cost, and market value of Contra Costa County Investment Pool were $7,300,695,569.24, $7,265,567,373.75, and $7,271,643,974.72 respectively. The weighted yield to maturity was 3.84% and the weighted average days to maturity were 285 days.
As of December 31, 2025, the Treasurer’s investment portfolio was in compliance with Government Code 53600 et. seq., and with the Treasurer’s current investment policy. It had no securities lending, reverse repurchase agreements or derivative. Historical activities combined with future cash flow projections indicate that the County should have sufficient liquidity to meet its cash flow needs for the next six months.
