Amortization expense related to all intangible assets in the aggregate was $2.3 million for both the three months ended June 30, 2018 and 2017, and $4.6 million for both the six months ended June 30, 2018 and 2017. We expect amortization of acquired intangible assets to be $4.6 million for the remainder of 2018 and $4.4 million in 2019.

The acquisition of Orad in 2015 resulted in goodwill of $32.6 million as of June 30, 2018 and December 31, 2017.
