We completed our annual evaluation of the carrying values of our goodwill and other indefinite-lived intangible assets as of November 1, 2017 and determined that the carrying values of each of our reporting units were less than their respective fair values and therefore, no impairment was required.

Other intangible assets consisted of the following:

Total amortization expense in 2017, 2016 and 2015 related to other intangible assets was $3.3 million, $3.4 million and $4.6 million, respectively.

In November 2017, we completed the acquisition of WSG, and in August 2016, we completed the acquisition of Pragmatic, which resulted in additions to amortizable intangible assets of $27.1 million and $1.7 million, respectively. See Note 2 for further discussion.

Estimated future amortization expense for the years ended December 31 is as follows:



(In thousands)	2018		2019		2020		2021		2022		Thereafter		Total
