All available-for-sale marketable debt securities held as of June 30, 2024 and December 31, 2023 had contractual maturities of less than one year. All of the Company's available-for-sale marketable debt securities in an unrealized loss position as of June 30, 2024 and December 31, 2023 were in a loss position for less than twelve months. Unrealized losses on available-for-sale debt securities as of June 30, 2024 and December 31, 2023 were not significant and were primarily due to
changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Accordingly, no allowance for credit losses related to the Company's available-for-sale debt securities was recorded for any periods presented. 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 bases, which may be at maturity.
