The Company had no realized gains or losses recognized on the sale or maturity of marketable securities during the three and six months ended June 30, 2026 and 2025. To date, the Company has not recognized any allowances for credit losses or impairments in relation to its available-for-sale marketable securities as these marketable securities are comprised of high credit quality, investment grade securities that the Company does not intend or expect to be required to sell prior to their anticipated recovery, and any decline in fair value of these securities is attributable to factors other than credit losses. All marketable securities with unrealized losses presented in the previous tables have been in a continuous unrealized loss position for less than 12 months or the loss is not material. The Company determined credit losses related to marketable securities were immaterial for the three and six months ended June 30, 2026 and 2025.
