​ The Company’s financial assets consist mainly of cash equivalents and marketable securities and are classified as Level 2 within the valuation hierarchy. The Company values its marketable securities utilizing independent pricing services which normally derive security prices from recently reported trades for identical or similar securities, making adjustments based on significant observable transactions. At each balance sheet date, observable market inputs may include trade information, broker or dealer quotes, bids, offers or a combination of these data sources. Contingent consideration liabilities measured at fair value using Level 3 inputs were $0.0 million as of December 31, 2024 and December 31, 2023. The valuation technique used to measure fair value of the Company’s Level 3 liabilities, which consist of contingent consideration related to the acquisition of Kolltan Pharmaceuticals, Inc. (“Kolltan”) in 2016, is primarily an income approach. The significant unobservable inputs used in the fair value measurement of the contingent consideration are estimates including probability of success, discount rates and amount of time until the conditions of the milestone payment are met. During the year ended December 31, 2022, the Company recorded a $6.9 million gain on fair value remeasurement of contingent consideration primarily due to the Company’s decision to deprioritize the CDX-1140 program. The assumptions related to determining the value of contingent consideration include a significant amount of judgment, and any changes in the underlying estimates could have a material impact on the amount of contingent consideration adjustment recorded in any given period. The Company did not have any transfers of assets or liabilities between the fair value measurement classifications during the years ended December 31, 2024 and 2023.
