Gross Unrealized Losses and Fair Value The fair values and gross unrealized losses on securities at March 31, 2021 and December 31, 2020, respectively, segregated by those securities that have been in an unrealized loss position for less than 12 months and 12 months or longer, are presented below.

On a quarterly basis, the Company assesses each security for credit impairment. For debt securities, the Company evaluates, where necessary, whether credit impairment exists by comparing the present value of the expected cash flows to the securities’ amortized cost basis. In determining whether a loss is temporary, the Company considers all relevant information including: ● the length of time and the extent to which the fair value has been less than the amortized cost basis; ● adverse conditions specifically related to the security, an industry, or a geographic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset-backed debt security, in the financial condition of the underlying loan obligors, including changes in technology or the discontinuance of a segment of the business that may affect the future earnings potential of the issuer or underlying loan obligors of the security or changes in the quality of the credit enhancement); ● the historical and implied volatility of the fair value of the security; ● the payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future; ● failure of the issuer of the security to make scheduled interest or principal payments; ● any changes to the rating of the security by a rating agency; and ● recoveries or additional declines in fair value subsequent to the balance sheet date. Agency obligations The unrealized losses associated with agency obligations were primarily driven by declines in interest rates and not due to the credit quality of the securities. These securities were issued by U.S. government agencies or government-sponsored entities and did not have any credit losses given the explicit government guarantee or other government support. Agency mortgage-backed securities (“MBS”) The unrealized losses associated with agency MBS were primarily driven by changes in interest rates and not due to the credit quality of the securities. These securities were issued by U.S. government agencies or government-sponsored entities and did not have any credit losses given the explicit government guarantee or other government support. Securities of U.S. states and political subdivisions The unrealized losses associated with securities of U.S. states and political subdivisions were primarily driven by declines in interest rates and were not due to the credit quality of the securities. Some of these securities are guaranteed by a bond insurer, but management did not rely on the guarantee in making its investment decision. These securities will continue to be monitored as part of the Company’s quarterly impairment analysis, but are expected to perform even if the rating agencies reduce the credit rating of the bond insurers. As a result, the Company expects to recover the entire amortized cost basis of these securities. The carrying values of the Company’s investment securities could decline in the future if the financial condition of an issuer deteriorates and the Company determines it is probable that it will not recover the entire amortized cost basis for the security. As a result, there is a risk that other-than-temporary impairment charges may occur in the future. Other-Than-Temporarily Impaired Securities Credit-impaired debt securities are debt securities where the Company has written down the amortized cost basis of a security for other-than-temporary impairment and the credit component of the loss is recognized in earnings. At March 31, 2021 and December 31, 2020, the Company had no credit-impaired debt securities and there were no additions or reductions in the credit loss component of credit-impaired debt securities during the quarters ended March 31, 2021 and 2020, respectively.
