Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) whether the Company intends to sell the security or more likely than not will be required to sell the security before its anticipated recovery. At March 31, 2020 and December 31, 2019, management performed an assessment for possible OTTI of the Company’s residential mortgage-backed securities on an issue-by-issue basis, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. The extent of individual analysis applied to each security depended on the size of the Company’s investment, as well as management’s perception of the credit risk associated with each security. Based on the results of the assessment, management believes impairment of these securities, at March 31, 2020 and December 31, 2019, to be temporary.
