Intangible assets and in-process research and development [Abstract] |
Intangible assets, in-process research and development | 8. Intangible assets, in-process research and development and goodwill As of October 1, 2016, the Company performed a qualitative assessment of goodwill associated with the Therapeutics and Vaccines reporting unit, Contract Manufacturing reporting unit, and the Medical Devices reporting unit. The Company completed its annual impairment assessments for its IPR&D assets and goodwill as of October 1, 2015 and determined that the fair value of the Company's IPR&D assets and reporting units was significantly in excess of carrying value. As of October 1, 2015, the Company performed a qualitative assessment of goodwill associated with the Therapeutics and Vaccines reporting unit, Contract Manufacturing reporting unit, and the Medical Devices reporting unit. Intangible assets consisted of the following:

For the years ended December 31, 2016, 2015 and 2014, the Company recorded amortization expense of $6.9 million, $7.4 million and $7.0 million, respectively, for intangible assets, which has been recorded in operating expenses, specifically selling, general and administrative and cost of product sales and contract manufacturing. As of December 31, 2016, the weighted average amortization period remaining for intangible assets is 75 months. Future amortization expense as of December 31, 2016 is as follows:
(in thousands) |  |  |

In September 2015, the Company received data for the leading molecule in the EV-035 series of molecules, GC-072, that indicated a potential toxicity issue. The Company considered this information an indicator of impairment of the related EV-035 series of molecules IPR&D asset, and completed an impairment assessment of this asset. Based on this assessment, the Company recorded a non-cash impairment charge of $9.8 million, which is included in the Company's statement of operations as research and development expense. The remaining carrying value of the EV-035 series of molecules IPR&D asset was $0.7 million as of December 31, 2015. This remaining amount was impaired during the year ended December 31, 2016 based upon delays in the development time line. The impairment assessment was performed using the income approach which discounts expected future cash flows to present value. The projected cash flows for the EV-035 series of molecules were based on key assumptions including: estimates of revenues and operating profits considering its stage of development, the time and resources needed to complete the development and approval of the product candidate, the life of the potential commercialized product and associated risks, including the inherent difficulties and uncertainties in developing a product candidate, such as obtaining marketing approval from the FDA and other regulatory agencies, and risks related to the viability of and potential for alternative treatments in any future target markets. As a result of the impairment of the EV-035 series of molecules IPR&D asset, the Company also performed an interim goodwill qualitative impairment assessment of the Vaccines and Therapeutics reporting unit, which contained $22.0 million of the goodwill reported on the Company's consolidated balance sheets as of September 30, 2015. Based on the assessment, the Company concluded that the goodwill was not impaired.
