We review our investment portfolio on a quarterly basis for indications of impairment. This review includes analyzing the length of time and the extent to which the fair value has been lower than the cost, the market liquidity for the investment, the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer, and our intent and ability to hold the investment for a period of time sufficient to recover the temporary loss.
 
The unrealized losses reported for corporate preferred stock over twelve months at September 30, 2016 relates to a single trust preferred security that was issued by the holding company of a small community bank. Typical of most trust preferred issuances, the issuer has the ability to defer interest payments for up to five years with interest payable on the deferred balance. In September 2014, the issuer paid all previously deferred interest that was due and all payments were current as of September 30, 2014. Since January 2015, the issuer has deferred its scheduled interest payment as allowed by the terms of the security agreement. The issuer’s subsidiary bank has incurred operating losses in the past due to increased provisions for loan losses but has generated a modest amount of net income over the past twelve months and continues to meet the regulatory requirements to be considered “well capitalized” based on its most recent regulatory filing. Based on a review of the issuer, it was determined that the trust preferred security was not other-than-temporarily impaired at September 30, 2016. The Company does not intend to sell the trust preferred security and has the intent and ability to hold it for a period of time sufficient to recover the temporary loss. Management believes that the Company will receive all principal and interest payments contractually due on the security and that the decrease in the market value is primarily due to a lack of liquidity in the market for trust preferred securities and the deferral of interest by the issuer. Management will continue to monitor the credit risk of the issuer and may be required to recognize other-than-temporary impairment charges on this security in future periods.
