The King County Investment Pool invests cash reserves for all County agencies and approximately 100 special districts and other public entities such as fire, school, sewer and water districts and other public authorities. It is one of the largest investment pools in the State, with an average asset balance of nearly $5 billion. On average, County agencies comprise 40 percent of the pool and outside districts 60 percent.

The Executive Finance Committee (EFC) establishes County investment policies and oversees the investment portfolio to ensure that specific investments comply with both those investment policies and State law. The Pool is only allowed to invest in certain types of highly-rated securities, including certificates of deposit, U.S. treasury obligations, federal agency obligations, municipal obligations, repurchase agreements and commercial paper.

February Gross Pool Earnings Rate: 2.08%
