The useful lives assigned to finite‑lived intangible assets included consideration of factors such as the Company’s past and expected experience related to customer retention rates, the remaining legal or contractual life of the underlying arrangement that resulted in the recognition of the intangible asset and the Company’s expected use of the intangible asset.

In its determination of these intangible assets as indefinite‑lived, the Company considered such factors as its expected future use of the intangible asset, legal, regulatory, technological and competitive factors that may impact the useful life or value of the intangible asset and the expected costs to maintain the value of the intangible asset. The Company expects that these intangible assets will maintain their value indefinitely. Accordingly, these assets are not amortized.    
The Company’s trade names were tested for impairment in the third quarter of 2017. The values of each trade name was determined using the relief-from-royalty method. Based on this evaluation, no trade names were determined to be impaired.

(4) GOODWILL AND INTANGIBLE ASSETS (Continued)
The Company’s annual impairment test of goodwill was performed during the third quarter of 2017, using the discounted cash flow method. As a result of that testing, the Company determined that its goodwill was not impaired, as the valuation of the reporting units exceeded their respective carrying values. The Company's offshore and other complex steel structures reporting unit with $14,645 of goodwill, is the reporting unit with the smallest cushion between its estimated fair value and its carrying value. Sales and profitability amounts for the first nine months of 2017 approximated the amounts in the 2016 annual impairment model. The 2017 model assumes continued expansion into other highly engineered steel product offerings, such as utility support structures, where the reporting unit completed profitable projects in the past. The Company will continue to monitor the outlook for wind energy in Europe and oil and natural gas prices, which will affect the sales demand assumptions in the five year model for this reporting unit. If demand for off and onshore structures for wind energy changes significantly, the Company will perform an interim impairment test for goodwill. The Company also tracks changes in the global economy that could impact future operating results of any of its reporting units.
