Realized gains or losses have not been significant and are included in other income, net, in the condensed statements of operations and comprehensive loss. Unrealized losses as of September 30, 2025 and December 31, 2024 were not material. All of the short-term available-for-sale securities held as of September 30, 2025 and December 31, 2024 had contractual maturities of less than one year. We determined that none of our available-for-sale securities were other-than-temporarily impaired as of September 30, 2025 and December 31, 2024, and no investment was in a continuous unrealized loss position for more than one year. Therefore, we believe that it is more likely than not that the investments will be held until maturity or a forecasted recovery of fair value. Based on our procedures under the expected credit loss model, including an assessment of unrealized losses in our portfolio, we concluded that any unrealized losses on our marketable securities were not attributable to credit and, therefore, we have not recorded an allowance for credit losses for these securities as of September 30, 2025 and December 31, 2024.
