Gross unrealized losses on available for sale securities included fifty-four (54) and eighty (80) debt securities at December 31, 2017 and December 31, 2016, respectively. The Company evaluates securities for other-than-temporary impairment on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. The Company’s mortgage-backed securities are issued by U.S. government agencies, which guarantee payments to investors regardless of the status of the underlying mortgages. Consideration is given to the length of time and the amount of an unrealized loss, the financial condition of the issuer, and the intent and ability of the Company to retain its investment in the issuer long enough to allow for an anticipated recovery in fair value. The fair value of a security reflects its liquidity as compared to similar instruments, current market rates on similar instruments, and the creditworthiness of the issuer. Absent any change in the liquidity of a security or the creditworthiness of the issuer, prices will decline as market rates rise and vice-versa. The primary cause of the unrealized losses at December 31, 2017 and December 31, 2016 was changes in market interest rates. Since the losses can be primarily attributed to changes in market interest rates and not expected cash flows or an issuer’s financial condition, the unrealized losses are deemed to be temporary and management does not intend to sell and it is unlikely that management will be required to sell the securities prior to their anticipated recovery. The Company monitors the financial condition of these issuers continuously and will record other-than-temporary impairment if the recovery of value is unlikely.

The Company’s securities are exposed to various risks, such as interest rate, market, currency and credit risks. Due to the level of risk associated with certain securities and the level of uncertainty related to changes in the value of securities, it is at least reasonably possible that changes in risks in the near term would materially affect securities reported in the financial statements. In addition, recent economic uncertainty and market events have led to unprecedented volatility in currency, commodity, credit and equity markets culminating in failures of some banking and financial services firms and government intervention to solidify others. These events underscore the level of investment risk associated with the current economic environment, and accordingly the level of risk in the Company’s securities.

Securities having a carrying value of $2.6 million at December 31, 2017 were pledged for various purposes required by law.
