For the three and nine months ended September 30, 2026 and 2025, realized gains and losses on marketable debt securities were immaterial. As of September 30, 2026 and December 31, 2025, the accrued interest receivable related to the Company's marketable debt securities was $2.8 million and $1.3 million, respectively, and was recorded in prepaid expenses and other current assets on the Consolidated Balance Sheets.

The Company reviews the available-for-sale marketable debt securities for declines in fair value below the cost basis each quarter. For any security whose fair value is below its amortized cost basis, the Company first evaluates whether it intends to sell the impaired security, or will otherwise be more likely than not required to sell the security before recovery. If either are true, the amortized cost basis of the security is written down to its fair value at the reporting date. If neither circumstance holds true, the Company assesses whether any portion of the unrealized loss is a result of a credit loss. Any amount deemed to be attributable to credit loss is recognized in the income statement, with the amount of the loss limited to the difference between fair value and amortized cost and recorded as an allowance for credit losses. The portion of the unrealized loss related to factors other than credit losses is recognized in other comprehensive income (loss).

The following is a summary of available-for-sale marketable debt securities in an unrealized loss position with no credit losses aggregated by investment category and length of time those individual securities have been in a continuous unrealized loss position reported as of September 30, 2026 (in thousands):

As of September 30, 2026 and December 31, 2025, the amortized cost of the available-for-sale marketable debt securities in an unrealized loss position was $347.5 million and $140.9 million, respectively.

As of September 30, 2026 and December 31, 2025, the Company does not intend to sell these investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis. The increase in unrealized losses for the nine months ended September 30, 2026 was primarily due to fluctuations in short-term interest rates. The Company does not believe the unrealized losses incurred during the period are due to credit-related factors. The credit ratings of the securities held remain of the highest quality. Moreover, the Company continues to receive payments of interest and principal as they become due, and our expectation is that those payments will continue to be received timely. Factors unknown to us at this time may cause actual results to differ and require adjustments to the Company’s estimates and assumptions in the future.
