Mortgage-backed securities are typically issued with stated principal amounts and are backed by pools of mortgages that have loans with varying maturities. The characteristics of the underlying pool of mortgages, such as prepayment risk, are passed on to the certificate holder. Accordingly, the term of mortgage-backed securities approximates the term of the underlying mortgages and can vary significantly due to prepayments.

The amortized cost and estimated fair value of securities available for sale at June 30,2022, by contractual maturity, are shown below.

There were 23 investments in an unrealized loss position at June 30, 2022, and two investments in an unrealized loss position at December 31, 2021. The Company does not consider any securities to be other-than-temporarily impaired. In estimating other-than-temporary impairment losses, the Company considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near term prospects of the issuer, (iii) that the Company does not intend to sell these securities, and (iv) it is more likely than not that the Company will not be required to sell before a period of time sufficient to allow for any anticipated recovery in fair value. The Company has reviewed the ratings of the issuers and has not identified any issues related to the ultimate repayment of principal because of credit concerns on these securities.

There were no securities pledged as collateral as of June 30, 2022 and December 31, 2021.
