As of
December 31, 2018,
the Company performed an evaluation for an equity security with a fair value below cost to determine if the unrealized loss was other-than-temporary. This evaluation considers a number of factors including, but
not
limited to, the length of time and extent to which the fair value has been less than cost, the financial condition and near term prospects of the issuer and the Company’s ability and intent to hold the security until fair value recovers. The assessment of the ability and intent to hold this security to recovery focuses on liquidity needs, asset/liability management objectives and security portfolio objectives. Based on the result of the evaluation, the Company concluded that as of
December 31, 2018,
the unrealized loss related to an equity security it owns was temporary.
