(1) Due to the new segment reporting effective in the first quarter of 2017, goodwill allocated to previous reporting units of Region One and Region Three have been aggregated into a single operating segment, Region One. See also Note 14. Business Unit Segment Information for further discussion on certain organizational and executive leadership changes.

The Company tests goodwill at least annually for impairment (the Company has elected to annually test for potential impairment of goodwill on the first day of the fourth quarter) and tests more frequently if indicators are present or changes in circumstances suggest that impairment may exist. The indicators include, among others, declines in sales, earnings or cash flows or the development of a material adverse change in business climate. The Company assesses goodwill for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment, referred to as a component.

Due to a change in the Company’s segment reporting effective in the first quarter of 2017, the goodwill allocated to certain previous reporting units have been aggregated into a single operating segment. See also Note 14. Business Unit Segment Information for further disclosure on the Company’s change in reporting segments effective in the first quarter of 2017.

As a result of the change in internal reporting segment information, the Company completed an interim quantitative impairment analysis (Step One) for goodwill as of January 1, 2017 and concluded that the estimated fair values of each of the Company's reporting units exceeded its carrying amount of net assets assigned to the respective reporting unit as of January 1, 2017 and immediately prior to the reorganization and therefore no further testing was required (Step Two). In conducting the January 1, 2017 goodwill Step One analysis, the Company analyzed actual and projected growth trends of the reporting units, gross margin, operating expenses and Earnings Before Interest, Taxes, Depreciation and Amortization ("EBITDA") (which also includes forecasted five-year income statement and working capital projection, a market-based weighted average cost of capital and terminal values after five years). The Company also assesses critical areas that may impact its business including economic conditions, market related exposures, competition, changes in service offerings and changes in key personnel. As part of the January 1, 2017 goodwill assessment, the Company engaged a third-party to evaluate its reporting units' fair values. No impairment was recorded as a result of the interim goodwill impairment test performed.
