Investments

Prior to the final determination of Basel III, investments were recorded as held-to-maturity due to the uncertainty of the capital treatment of available-for-sale investments. Upon the issuance of the final ruling, the Company opted out of the Other Comprehensive Income treatment of available-for-sale investments permitted under Basel III. Due to the change in capital treatment under the final ruling of Basel III, the Company’s purpose of recording investments as held-to-maturity changed; therefore, during the period ended March 31, 2016, the Company reclassified $52.4 million, with unrealized holding gains of $1.8 million, of the remaining held-to-maturity investments into available-for-sale investments.

There were no investment securities held-to-maturity at September 30, 2016.

Investment securities with a carrying value of $97.5 million at September 30, 2016, were pledged to secure public funds, repurchase agreements and potential borrowings at the Federal Reserve discount window.

The Company's investment portfolio includes securities that are in an unrealized loss position as of September 30, 2016, the details of which are included in the following table. Although these securities, if sold at September 30, 2016 would result in a pretax loss of $527 thousand the Company has no intent to sell the applicable securities at such fair values, and maintains the Company has the ability to hold these securities until all principal has been recovered. It is not more likely than not the Company would sell any securities at a loss for liquidity purposes. Declines in the fair values of these securities can be traced to general market conditions which reflect the prospect for the economy as a whole. When determining other-than-temporary impairment on securities, the Company considers such factors as adverse conditions specifically related to a certain security or to specific conditions in an industry or geographic area, the time frame securities have been in an unrealized loss position, the Company’s ability to hold the security for a period of time sufficient to allow for anticipated recovery in value, whether or not the security has been downgraded by a rating agency, and whether or not the financial condition of the security issuer has severely deteriorated. As of September 30, 2016, the Company considers all securities with unrealized loss positions to be temporarily impaired, and consequently, does not believe the Company will sustain any material realized losses as a result of the current temporary decline in market value.
