OTHER-THAN-TEMPORARILY IMPAIRED SECURITIES

Management assesses whether the Company intends to sell or it is more-likely-than-not that the Company will be required to sell a security before recovery of its amortized cost basis less any current-period credit losses. For debt securities that are considered other-than-temporarily impaired and that the Company does not intend to sell and will not be required to sell prior to recovery of the amortized cost basis, the Company separates the amount of the impairment into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the security's amortized cost basis and the present value of its expected future cash flows. The remaining difference between the security's fair value and the present value of expected future cash flows is due to factors that are not credit related, which are recognized in other comprehensive income.

The present value of expected future cash flows is determined using the best-estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best-estimate cash flows vary depending on the type of security. The asset-backed securities cash flow estimates are based on bond specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds, and structural support, including subordination and guarantees.

The Company has a process in place to identify debt securities that could potentially have a credit or interest-rate related impairment that is other-than-temporary. This process involves monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts, and cash flow projections as indicators of credit issues. On a quarterly basis, management reviews all securities to determine whether an other-than-temporary decline in value exists and whether losses should be recognized. Management considers relevant facts and circumstances in evaluating whether a credit or interest-rate related impairment of a security is other-than-temporary. Relevant facts and circumstances considered include: (a) the extent and length of time the fair value has been below cost; (b) the reasons for the decline in value; (c) the financial position and access to capital of the issuer, including the current and future impact of any specific events; and (d) for fixed maturity securities, the Company's intent to sell a security or whether it is more-likely-than-not the Company will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity, and for equity securities, the Company's ability and intent to hold the security for a period of time that allows for the recovery in value.

The Company has not recorded impairment charges through income on securities for the three or six months ended June 30, 2017 or the year ended December 31, 2016.

Certain investments within the Company's portfolio had unrealized losses at June 30, 2017 and December 31, 2016, as shown in the tables above. The unrealized losses were caused by increases in market interest rates. Because the Company does not intend to sell the investments and management believes it is unlikely that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider the investments to be other-than-temporarily impaired at June 30, 2017 or December 31, 2016.

Restricted Securities

The restricted security category is comprised of stock in the Federal Home Loan Bank of Atlanta (FHLB) and the Federal Reserve Bank (FRB). These stocks are classified as restricted securities because their ownership is restricted to certain types of entities and the securities lack a market. Therefore, FHLB and FRB stock is carried at cost and evaluated for impairment. When evaluating these stocks for impairment, their value is determined based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. Restricted stock is viewed as a long-term investment and management believes that the Company has the ability and the intent to hold this stock until its value is recovered.
