Net unrealized gains and losses on available-for-sale debt securities were insignificant in the three and nine months ended September 30, 2026 and 2025. Cumulative unrealized losses on available-for-sale debt securities were insignificant at September 30, 2026 and December 31, 2025. At September 30, 2026, we had no intention to sell the available-for-sale debt securities, and it was unlikely that we would be required to sell the available-for-sale debt securities before recovery of their amortized cost basis. No allowance for credit losses was recorded on available-for-sale debt securities in an unrealized loss position at September 30, 2026 and December 31, 2025.
