The Company performs its annual goodwill and indefinite lived assets impairment testing during the fourth quarter. Based on the results of that test, no impairment was indicated in 2019. The Company will continue to monitor changes in circumstances and test more frequently if those changes indicate that assets might be impaired.

During the year ended December 31, 2018, the Company recorded a non-cash goodwill impairment charge of $82.2 million in the EURAF reporting unit. The goodwill impairment charge resulted from a reduction in the estimated fair value of the reporting unit based on the continued decline in the Company’s equity market capitalization and lower forecasted results in the region.

A considerable amount of management judgment and assumptions are required in performing the impairment tests as it relates to revenue growth rates and projected operating income. While the Company believes the judgments and assumptions are reasonable, different assumptions could change the estimated fair value and, therefore, additional impairment charges could be required. Weakening industry or economic trends, disruptions to our business, unexpected significant changes or planned changes in the use of the assets or in entity structure may adversely impact the assumptions used in the valuations. The Company continually monitors market conditions and determines if any additional interim reviews of goodwill, other intangibles or long-lived assets are warranted. In the event the Company determines that assets are impaired in the future, the Company would recognize a non-cash impairment charge, which could have a material adverse effect on the Company’s Consolidated Balance Sheets and Results of Operations.
