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 on impaired securities other than the corporate preferred stock are the result of changes in interest rates. The unrealized losses reported for the corporate preferred stock at
March 31, 2019
relates to a single trust preferred security that was issued by the holding company of a small community bank. As of
March 31, 2019
all payments were current on the trust preferred security and the issuer’s subsidiary bank was considered to be “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
March 31, 2019
as the Company does
not
intend to sell 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. 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.
