In 2017, a goodwill impairment test was performed by management with the assistance of a third-party valuation firm. As of December 31, 2017, it was concluded that the fair value of each of our reporting units exceeded their carrying values, and accordingly, no goodwill impairment was required.

Changes in the net carrying value amount of goodwill were as follows:



	Total
Goodwill as of December 31, 2015	$	33,865
Increase from acquisitions	27,879
Goodwill as of December 31, 2016	61,744
Increase from acquisition	9,313
