All of the Company's marketable securities are due within one year or less. The Company did not realize any gains or losses recognized on the sale of marketable securities during the years ended December 31, 2024 and 2023, and, as a result, the Company did not reclassify any amounts out of accumulated comprehensive loss.

As of December 31, 2024, the Company's debt security portfolio did not have any securities that were in an unrealized loss position. As of December 31, 2023, the Company's debt security portfolio consisted of one security that was in an unrealized loss position and had an aggregate fair value of $5.0 million. There were no securities in an unrealized loss position for greater than 12 months as of December 31, 2024 and 2023. The unrealized losses on the Company's marketable securities as of December 31, 2023 were caused by market interest rate increases.

The Company has the intent and ability to hold securities with unrealized losses until recovery. As a result, the Company did not record any charges for credit-related impairments for any debt securities in its portfolio during the years ended December 31, 2024, 2023 and 2022.
