On December 30, 2009, in connection with the acquisition of Anika S.r.l., the Company purchased various intangible assets. In 2015, the Company recorded an impairment charge totaling $0.7 million to write-off in-process research and development that was recorded in connection with its acquisition of Anika S.r.l. Subsequent to an evaluation in the fourth quarter of the ongoing research and development efforts surrounding the Hemostatic Patch IPR&D project, the Company determined it would discontinue further development efforts needed to commercialize this technology. As a result of this decision, an impairment charge was recorded. These amounts are included in research and development expenses on the Company’s consolidated statements of operations. The Company performed an annual assessment of IPR&D intangible assets as of November 30, 2017. Based upon that assessment, for the fiscal year 2017 there were no events or changes in circumstances that would result in a change in the carrying value of IPR&D. Total amortization expense was $1.0 million, $1.1 million, and $1.1 million for the years ended December 31, 2017, 2016, and 2015, respectively. Amortization expense on intangible assets is expected to be approximately $1.0 million in 2018, $1.0 million annually through 2021, and approximately $3.1 million in aggregate thereafter.
