For purposes of the maturity table, mortgage-backed securities, which are not due at a single maturity date, have been allocated over maturity groupings based on the weighted-average contractual maturities of underlying collateral. The mortgage-backed securities generally mature earlier than their weighted-average contractual maturities because of principal prepayments. The following tables reflect gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, as of September 30, 2021 and December 31, 2020. There were no investments held-to-maturity in an unrealized loss position as of September 30, 2021.

Management evaluates securities for other-than-temporary impairment no less frequently than quarterly and more frequently when economic or market concerns warrant such evaluation. Consideration is given to: (i) the length of time and the extent to which fair value has been less than cost; (ii) the financial condition and near-term prospects of the issuer; (iii) whether the Company intends to sell the securities; and (iv) whether it is more likely than not that the Company will be required to sell the securities before recovery of their amortized cost bases. As of September 30, 2021, 11 debt securities had been in a loss position for more than 12 months, and six debt securities had been in a loss position for less than 12 months. As of December 31, 2020, nine debt securities had been in a loss position for more than 12 months, and 11 debt securities had been in a loss position for less than 12 months. As of both September 30, 2021 and December 31, 2020, the losses for all securities were considered to be a direct result of the effect that the prevailing interest rate environment had on the value of debt securities and were not related to the creditworthiness of the issuers. There was a substantial decrease in interest rates during the year ended December 31, 2020, including a 150-basis point reduction in the federal funds rate in March 2020. This resulted in significant increases in the fair value of debt securities and a corresponding decline in the number of securities in a loss position during 2020 and the nine months ended September 30, 2021. Most of the securities in an unrealized loss position as of both September 30, 2021 and December 31, 2020 were residential or commercial mortgage-backed securities that are either direct obligations of the U.S. government or government-sponsored entities and, accordingly, have little associated credit risk. Further, the Company has the current intent and ability to retain its investments in the issuers for a period of time that management believes to be sufficient to allow for any anticipated recovery in fair value. Therefore, the Company did not recognize any other-than-temporary impairments as of September 30, 2021 or December 31, 2020. Investment securities with a carrying value of $56.9 million and $72.9 million as of September 30, 2021 and December 31, 2020, respectively, were pledged to secure public deposits and for other purposes.
