Contractual maturities for mortgage-backed securities are not presented, as expected maturities on mortgage-backed securities may differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without penalties. There were no sales of held-to-maturity securities for the years ended December 31, 2021, 2020 and 2019. At December 31, 2021, and December 31, 2020, debt securities held-to-maturity with a carrying value of $2.1 million and $5.9 million, respectively, were pledged to secure repurchase agreements and deposits. See Note 10 - “Borrowings” for further discussion regarding securities pledged or encumbered for borrowings. At December 31, 2021 and 2020, there were no debt securities held-to-maturity in an unrealized loss position. The Company's held-to-maturity securities are residential mortgage-backed securities issued by Ginnie Mae, Freddie Mac and Fannie Mae, and it is expected that the securities will not be settled at prices less than the amortized cost bases of the securities as such securities are backed by the full faith and credit of and/or guaranteed by the U.S. Government. Accordingly, no allowance for credit losses has been recorded for these securities. The Company has made the accounting policy election to exclude accrued interest receivable on held-to-maturity securities from the estimate of credit losses. Accrued interest receivable associated with held-to-maturity securities totaling $16,000 at December 31, 2021 was reported in accrued interest receivable on the consolidated balance sheet.
