Banking and Thrift [Abstract] |
Funds Restrictions and Reserve Balance | Funds Restrictions and Reserve Balance Transfers of funds from the banking subsidiary to the parent company in the form of loans, advances, and cash dividends are restricted by federal and state regulatory authorities. At December 31, 2017, the aggregate amount of unrestricted funds which could be transferred from the banking subsidiary to the parent company, without prior regulatory approval, totaled $4.5 million. The amount of unrestricted funds is generally determined by subtracting the total dividend payments of the Bank from the Bank’s net income for that year, combined with the Bank’s retained net income for the preceding two years. The Bank must maintain a reserve against its deposits in accordance with Regulation D of the Federal Reserve Act. For the final weekly reporting period in the years ended December 31, 2017 and 2016, the aggregate amounts of daily average required balances were approximately $7.4 million and $6.0 million, respectively.
