​ All of the securities with unrealized losses in the portfolio have modest duration risk, low credit risk, and minimal losses when compared to total amortized cost. The unrealized losses on debt securities that exist are the result of market changes in interest rates since original purchase and are not related to credit concerns. Because the Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized cost bases, which may be at maturity for debt securities, the Company considers the unrealized losses to be temporary. There were seven available-for-sale securities in an unrealized loss position at December 31, 2020, of which four were mortgage-backed and three were U.S. Government agencies. There were four held-to-maturity securities in an unrealized loss position at December 31, 2020, of which two were U.S. Government agency bonds, one corporate bond and one mortgage-backed security. The following table provides information on the amortized cost and estimated fair values of investment securities by maturity date at December 31, 2020. ​
