Other-Than-Temporary-Impairment

Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Investment securities are generally evaluated for OTTI under FASB Accounting Standards Codification (“ASC”) 320, Investments – Debt and Equity Securities. Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, whether the market decline was affected by macroeconomic conditions and whether the Company 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. In analyzing an issuer’s financial condition, the Company may consider whether the securities are issued by the federal government or its agencies, or U.S. government sponsored enterprises, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. 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 an entity 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. 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, 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. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income or loss. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

As of March 31, 2017, the Company’s security portfolio consisted of 511 securities, 178 of which were in an unrealized loss position. The majority of the unrealized losses on the Company’s securities are related to its holdings of mortgage-backed securities, collateralized mortgage obligations, state and political subdivision securities, and Small Business Administration securities as discussed below.

Unrealized losses on debt securities issued by state and political subdivisions have not been recognized into income. These securities have maintained their investment grade ratings and management does not have the intent and does not expect to be required to sell these securities before their anticipated recovery. The fair value is expected to recover as the securities approach their maturity date.

All of the Company’s holdings of collateralized mortgage obligations and residential mortgage-backed securities were issued by U.S. government-sponsored entities. Unrealized losses on these securities have not been recognized into income. Because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, the issues are guaranteed by the issuing entity which the U.S. government has affirmed its commitment to support, and because the Company does not have the intent to sell these residential mortgage-backed securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be OTTI.

Management does not believe any unrealized losses on Small Business Administration securities represent an OTTI. The securities are issued and backed by the full faith and credit of the U.S. government and the Company does not have the intent and does not anticipate that it will be required to sell these securities before their anticipated recovery. The fair value of these securities is expected to recover as they approach their maturity.
