During the six months ended June 30, 2022, the Company sold $226 million of debt securities with an average yield of 0.16%, which were subsequently reinvested in $220 million of debt securities with an average yield of 1.86%. The Company used specific identification to reclassify the unrealized loss in other comprehensive income to a realized loss, as shown in the consolidated statements of comprehensive income. There were no sales of debt securities and therefore no proceeds from sales or realized securities gains or losses on available for sale debt securities for the six months ended June 30, 2021. Realized gains/losses on debt and equity securities are reported as securities transactions within the noninterest income section of the consolidated statement of comprehensive income. The following table summarizes debt securities with unrealized losses, segregated by the duration of the unrealized loss, at June 30, 2022 and December 31, 2021 respectively:

The Company has the ability and intent to hold the debt securities classified as held for investment until they mature, at which time the Company will receive full value for the debt securities. Furthermore, as of June 30, 2022 and December 31, 2021, the Company also had the ability and intent to hold the debt securities classified as available for sale for a period of time sufficient for a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying debt securities were purchased. The fair value of those debt securities having unrealized losses is expected to recover as the securities approach their maturity date or repricing date, or if market yields for such investments decline. The Company has no intent or requirement to sell before the recovery of the unrealized loss; therefore, no impairment loss was realized in the Company’s consolidated statement of comprehensive income.
