The Company tests goodwill for impairment annually as of December 31 and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount, as discussed in further detail in Note 2.
 
The Company performed goodwill impairment testing using the quantitative approach for all reporting units that had goodwill at December 31, 2017 and 2016, and no impairments were recorded.
