Regulations of the Board of Governors of the Federal Reserve System require that the Bank maintain minimum reserve balances either on hand or on deposit with the Federal Reserve Bank of San Francisco ("FRB") based on a percentage of deposits. The amounts of such balances as of March 31, 2018 and 2017 were $1.7 million and $2.5 million, respectively, which were in compliance with the minimum reserve requirements.
