Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. In accordance with ASC 350, Intangibles – Goodwill and Other, goodwill is not amortized, but instead is tested for impairment annually, or more frequently if circumstances indicate a possible impairment may exist. Absent any interim indicators of impairment, the Company tests for goodwill impairment as of the first day of the fourth fiscal quarter of each year.

The fair value estimates used in the goodwill impairment analysis require significant judgment. The fair value estimates were based on assumptions management believes to be reasonable, but that are inherently uncertain, including estimates of future revenue and operating margins and assumptions about the overall economic climate and the competitive environment for the business.

The Company most recently recognized an impairment of a portion of its goodwill in the North America reportable segment as of December 31, 2018, as outlined below. The Company further considered indicators for impairment at June 30, 2019 given the significant level of goodwill remaining in the reportable segment as well as the recent impairment test. The fair value determination of the reporting unit primarily relies on management judgments around timing of generating revenue from recent new customer wins as well as timing of benefits expected to be received from the significant restructuring actions currently underway (see Note 6). If assumptions surrounding either of these factors change, then a future impairment charge may occur.

2018 Goodwill Impairment Charges

During the quarter ended September 30, 2018, the Company changed its segments and re-evaluated its reporting units. This change required an interim impairment assessment of goodwill. The Company determined an enterprise value for its North America, EMEA and LATAM reporting units that considered both discounted cash flow and guideline public company methods. The Company further compared the enterprise value of each reporting unit to its respective carrying value. The enterprise value for North America exceeded its carrying value, which indicated that there was no impairment, whereas enterprise values for the EMEA and LATAM reporting units were less than their respective carrying values, and as a result the Company recognized $20.8 million and $7.1 million goodwill impairment charges, respectively.

As of December 31, 2018, the Company performed an interim impairment assessment due to a triggering event caused by a sustained decrease in the Company's stock price. The Company determined an enterprise value for its North America reporting unit that considered both the discounted cash flow and guideline public company methods. The Company further compared the enterprise value of the reporting unit to its carrying value. The enterprise value for the North America reporting unit was less than its carrying value and resulted in a $18.4 million non-cash goodwill impairment charge. No tax benefit was recognized on such charge, and this charge had no impact on the Company's cash flows or compliance with debt covenants.

Prior to this 2018 activity, the Company previously recorded gross and accumulated impairment losses of $75.4 million resulting from prior period goodwill impairment tests.
