Other‑Than‑Temporary‑Impairment

Management evaluates securities for OTTI at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI model. Investment securities are generally evaluated for OTTI under ASC 320.

In determining OTTI under ASC 320, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near‑term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other‑than‑temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time.

When OTTI occurs, the amount of the OTTI recognized in earnings depends on whether the Company intends to sell the security or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, less any current period credit loss. If an entity intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, less any current period credit loss, the OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current period loss, the OTTI shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment.

As of December 31, 2017, the Company’s security portfolio consisted of 1,019 securities, 162 of which were in an unrealized loss position. Unrealized losses on state and municipal securities of $442 have not been recognized into income because management has the ability to hold for a period of time sufficient to allow for any anticipated recovery in fair value and it is unlikely that management will be required to sell the securities before their anticipated recovery. The decline in value is primarily attributable to changes in interest rates. The fair value of these debt securities is expected to recover as the securities approach their maturity date.

At December 31, 2017, all of the mortgage‑backed securities held by the Company were issued by U.S. government‑sponsored entities and agencies, primarily Fannie Mae and Freddie Mac, institutions which the government has affirmed its commitment to support. Because the decline in fair value of approximately $3,792 is attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these mortgage‑backed securities and it is unlikely that it will be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other‑than‑temporarily impaired at December 31, 2017.

The Company’s collateralized mortgage obligation securities portfolio includes agency collateralized mortgage obligations which were issued by U.S. government-sponsored entities and agencies. The government has affirmed its commitment to support. These securities with an unrealized loss had a market value of $236,787 and unrealized losses of approximately $3,450 at December 31, 2017. The Company monitors to ensure it has adequate credit support and as of December 31, 2017, the Company believes there is no OTTI and does not have the intent to sell these securities and it is unlikely that it will be required to sell the securities before their anticipated recovery. All securities are investment grade.
