Intangible assets related to our acquisitions are recorded at their fair value at the acquisition date. The change in intangible assets during 2016 is primarily due to the acquisition of BearWare, MK Data, and Oz described in Note 3 to these consolidated financial statements. The balance of the change in intangible assets is due to foreign currency translation and amortization.

Intangible assets with a finite life are amortized into income over their useful lives. Amortization expense for existing intangible assets is expected to be $133.6 million over the following periods: $26.1 million for 2017, $21.3 million for 2018, $19.3 million for 2019, $18.6 million for 2020, $15.2 million for 2021 and $33.1 million thereafter. Expected future amortization expense is subject to fluctuations in foreign exchange rates and assumes no future adjustments to acquired intangible assets.
