Actual maturities may differ for certain debt securities that may be called by the issuer prior to the contractual maturity. Actual maturities usually differ from contractual maturities on agency MBS because the mortgages underlying the securities may be prepaid, usually without any penalties. Therefore, these agency MBS are shown separately and are not included in the contractual maturity categories in the above maturity summary.

The Company evaluates all investment securities on a quarterly basis, and more frequently when economic conditions warrant, to determine if an OTTI exists. A security is considered impaired if the fair value is lower than its amortized cost basis at the report date. If impaired, management then assesses whether the unrealized loss is OTT.

An unrealized loss on a debt security is generally deemed to be OTT and a credit loss is deemed to exist if the present value of the expected future cash flows is less than the amortized cost basis of the debt security. The credit loss component of OTTI write-down is recorded, net of tax effect, through net income as a component of net OTTI losses in the consolidated statement of income, while the remaining portion of the impairment loss is recognized in OCI, provided the Company does not intend to sell the underlying debt security and it is "more likely than not" that the Company will not have to sell the debt security prior to recovery. Declines in the fair values of individual equity securities that are deemed by management to be OTT are reflected in noninterest income when identified.

Management considers the following factors in determining whether OTTI exists and the period over which the security is expected to recover:


•	The length of time, and extent to which, the fair value has been less than the amortized cost;


•	Adverse conditions specifically related to the security, industry, or geographic area;


•	The historical and implied volatility of the fair value of the security;


•	The payment structure of the debt security and the likelihood of the issuer being able to make payments that may increase in the future;


•	Failure of the issuer of the security to make scheduled interest or principal payments;


•	Any changes to the rating of the security by a rating agency;


•	Recoveries or additional declines in fair value subsequent to the balance sheet date; and


•	The nature of the issuer, including whether it is a private company, public entity or government-sponsored enterprise, and the existence or likelihood of any government or third party guaranty.

The Company has the ability to hold the investment securities that had unrealized losses at June 30, 2017 for the foreseeable future and no declines were deemed by management to be OTT.
