Intangible Assets and Goodwill
Intangible Assets and Goodwill	(6) Intangible Assets and Goodwill Intangible Assets, Net As a result of the discontinuation of the Glemba program, the Company concluded that the finite-lived intangible asset related to its Amgen Fremont license rights to develop and commercialize Glemba was fully impaired and a non-cash impairment charge of $6.9 million was recorded in the first quarter of 2018. Amortization expense related to this finite-lived intangible asset was $0.0 million and $0.2 million for the three months ended March 31, 2019 and 2018, respectively. At March 31, 2019 and 2018, the Company recorded indefinite-lived intangible assets of $48.7 million. Indefinite-lived intangible assets consist of acquired in-process research and development (“IPR&D”) related to the development of CDX-3379, the anti-KIT program and the TAM program. CDX-3379 is in Phase 2 development. The anti-KIT and TAM programs are in preclinical development. As of March 31, 2019, none of the Company’s IPR&D assets had reached technological feasibility nor did any have alternative future uses. The Company performs an impairment test on IPR&D assets at least annually, or more frequently if events or changes in circumstances indicate that IPR&D assets may be impaired. As a result of the discontinuation of the Glemba program, the Company concluded that the Glemba IPR&D asset was fully impaired and a non-cash impairment charge of $11.8 million was recorded in the first quarter of 2018. Due to the nature of IPR&D projects, the Company may experience future delays or failures to obtain regulatory approvals to conduct clinical trials, failures of such clinical trials or other failures to achieve a commercially viable product, and as a result, may recognize further impairment losses in the future. Goodwill The Company evaluated goodwill for potential impairment due to the discontinuation of the Glemba program. The carrying amount of the Company was compared to the Company’s fair value. The Company’s fair value assessment reflected a number of significant management assumptions and estimates including the Company’s probability forecasts for pipeline assets, income taxes, capital expenditures, market premium and changes in working capital requirements. Changes in these assumptions and/or discount rates could materially impact the Company’s conclusions. Through this assessment, it was determined that the carrying amount of the Company exceeded its fair value by over $91.0 million. As such, the full goodwill asset was considered impaired and a charge of $91.0 million was recorded during the first quarter of 2018.
