In 2016, we recorded additions to goodwill and other intangible assets of $14 million and $9 million, respectively, due to an acquisition in 2016 and the revision to the preliminary purchase price allocation of the Anite acquisition. We recorded $4 million of foreign exchange translation impact to other intangible assets in 2016.

In 2015, we recorded additions to goodwill of $327 million related to two businesses including the Anite acquisition discussed in Note 3, "Acquisition of Anite." During the year, we also recorded $246 million of additions to other intangibles related to the same acquisitions. We recorded $3 million of foreign exchange translation impact to other intangibles in 2015.

Amortization of other intangible assets was $43 million in 2016, $15 million in 2015, and $8 million in 2014. Future amortization expense related to existing finite-lived purchased intangible assets is estimated to be $41 million in 2017, $38 million in 2018, $37 million in 2019, $37 million in 2020, $29 million in 2021, and $14 million thereafter.
