Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and intangible assets | Note 7 – Goodwill and intangible assets Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in business combinations accounted for under the purchase method of accounting. The Company performed the annual goodwill impairment assessment using a qualitative approach to determine whether it is more likely than not that the fair value of goodwill is less than its carrying value. In performing the qualitative assessment, we identify and consider the significance of relevant key factors, events, and circumstances that affect the fair value of our goodwill. These factors include external factors such as macroeconomic, industry, and market conditions, as well as entity-specific factors, such as our actual and planned financial performance. If the results of the qualitative assessment conclude that it is not more likely than not that the fair value of goodwill exceeds its carrying value, additional quantitative impairment testing is performed. The impairment test was performed at the operating segment level as the acquired businesses have been fully integrated into our existing structure. Based on the results of the impairment assessment performed, we concluded that it is more likely than not that the fair value of our goodwill significantly exceeds the carrying value. At December 31, 2016 the Company had $0.9 million of goodwill, of which $0.4 million is attributable to the acquisition of Polar Technologies, LLC and $0.4 million is attributable to the acquisition of a supplier of refrigerants and compressed gases. Please see Note 12 for further details. The Company’s other intangible assets consist of the following:

The amortization of intangible assets for the years ended December 31, 2016, 2015, and 2014 were $0.5 million, $0.5 million and $0.1 million respectively.
