For available-for-sale debt securities in an unrealized loss position, the Company does not intend to sell these securities and it is more likely than not that the Company will hold these securities until maturity or a recovery of the cost basis. The Company determined that the decline in fair value of these securities was not due to credit-related factors, and no allowance for expected credit losses was recorded as of December 31, 2025 and 2024. Realized gains and losses were not material for the years ended December 31, 2025, 2024, and 2023.
