Securitiesheld-to-maturity decreased to $3,703,000 on September 30, 2018 from $5,713,000 on December 31, 2017.

Financial’s investment in Federal Home Loan Bank of Atlanta (FHLBA) stock totaled $564,000 at September 30, 2018 and $607,000 at December 31, 2017, a decrease of $43,000. This decrease is attributable to the FHLBA’s redemption of stock as a result of the repayment of a $10,000,000 advance earlier this year. FHLBA stock is generally viewed as a long-term investment and because there is no market for the stock other than other Federal Home Loan Banks or member institutions, FHLBA stock is viewed as a restricted security. Therefore, when evaluating FHLBA stock for impairment, its value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value.
Liquidity and Capital
At September 30, 2018, Financial, on a consolidated basis, had liquid assets of $102,797,000 in the form of cash, interest-bearing and noninterest-bearing deposits with banks, andavailable-for-sale investments. Of this amount, approximately $16,611,000 (representing current book value) of theavailable-for-sale securities are pledged as collateral with $8,169,000 pledged as security for public deposits, and $8,442,000 pledged as security on a line of credit the Bank may draw on from time to time to meet liquidity needs. This line of credit currently has a zero balance. Management believes that liquid assets were adequate at Septmeber 30, 2018. Management anticipates that additional liquidity will be provided by the growth in deposit accounts and loan repayments at the Bank. In addition, if additional liquidity is needed, the Bank has the ability to purchase federal funds on the open market, borrow from the FHLBA using loans or investments within the Bank’s portfolio as collateral, and to borrow from the Federal Reserve Bank’s discount window.
Management is not aware of any trends, events or uncertainties that are reasonably likely to have a material negative impact on Financial’s short-term or long-term liquidity. Based in part on recent loan growth, the Bank is monitoring liquidity to ensure it is able to fund future loans.
