As of September 30, 2024 and December 31, 2023, the Company’s cash equivalents consisted of money market funds, which were valued based upon Level 1 inputs. The Company’s marketable securities as of September 30, 2024 consisted of corporate debt, asset-backed debt, foreign government agency debt, and U.S. government and government agency debt securities, which were all valued based upon Level 2 inputs. The Company’s marketable securities as of December 31, 2023 consisted of commercial paper and corporate debt, asset-backed debt, foreign government agency debt, and U.S. government and government agency debt securities, which were all valued based upon Level 2 inputs.

In determining the fair value of its Level 2 investments, the Company relies on quoted prices for identical securities in markets that are not active. These quoted prices are obtained by the Company with the assistance of a third party pricing service based on available trade, bid and other observable market data for identical securities. During the three and nine months ended September 30, 2024 and 2023, there were no transfers into or out of Level 3.

The overall $3.8 million increase in the fair value of the contingent consideration liability during the nine months ended September 30, 2024 was primarily due to changes in estimated sales levels, changes to the probability of success for certain drug candidates, and the passage of time.

As of September 30, 2024 and December 31, 2023, the fair value of the Company’s available-for-sale marketable securities by type of security was as follows:
