Customer List Impairment Charges

In the fourth quarter of 2015, the Company recognized a $0.2 million non-cash, intangible asset impairment charge related to certain customer lists acquired in prior year business combinations in the EMEA segment. Due to the global realignment discussed in Note 6, the Company evaluated the affected markets and identified certain customer lists for which undiscounted projected cash flows of the customers in those markets did not exceed the recorded book value of the customer lists. As such, the Company recorded an impairment charge of $0.2 million to reduce the customer lists to their respective fair values.

In the fourth quarter of 2014, the Company recognized a $2.7 million non-cash, intangible asset impairment charge related to certain customer lists acquired in prior year business combinations. Due to the loss of specific customers included in the lists, the undiscounted projected cash flows from those customers did not exceed the recorded book value of the customer lists as of December 31, 2014. As such, the Company recorded an impairment charge of $2.7 million to reduce the customer lists to their respective fair values. Of the total charge, $2.4 million related to customer lists in the North America segment, and $0.3 million related to customers lists in the EMEA segment.
