County Treasury Investment Pool Yields

The Treasury Quarterly Yield is the rate, expressed as a percentage, at which the County is currently earning interest on its investments, before deducting the costs of banking services and managing the pool.

The Treasury Apportioned Yield is the rate, expressed as a percentage, at which the County is currently earning interest on its investments, after deducting costs of banking services and managing the pool.

The LAIF Apportioned Yield is the interest rate paid by the State of California on deposits in the State’s investment pool, known as the Local Agency Investment Fund or simply LAIF.  The County uses LAIF’s rate as a benchmark for yield, because both operate in a similar manner and have similar restrictions. LAIF is a much larger fund, with assets of about $70 billion, compared to the County at under $1 billion.
