Goodwill and Intangible Assets Disclosure [Abstract]

The Company has no reporting units which have a goodwill balance at December 31, 2019.

Goodwill is tested for impairment annually in the fourth quarter, or more frequently if circumstances indicate a potential impairment. During the fourth quarter of 2017, the Company adopted ASU 2017-04, which eliminates Step 2 from the goodwill impairment test. If the carrying amount exceeds the reporting unit’s fair value, the Company will recognize an impairment charge for the excess amount.

During the second quarter of 2018, the Company recognized a goodwill impairment charge of $37.2 million in the Energy Chemistry Technologies (“ECT”) reporting unit, which resulted from sustained under-performance and lower expectations related to the reporting unit. As a result of these factors, a qualitative analysis, and additional risks associated with the business, the Company concluded that sufficient indicators existed to require an interim quantitative assessment

of goodwill for that reporting unit as of June 30, 2018. The fair value of the reporting unit was estimated based on an analysis of the present value of future discounted cash flows. The significant estimates used in the discounted cash flows model included the Company’s weighted average cost of capital, projected cash flows and the long-term rate of growth. The assumptions were based on the actual historical performance of the reporting unit and took into account a recent weakening of operating results in an improving market environment. The excess of the reporting unit’s carrying value over the estimated fair value was recorded as the goodwill impairment charge during the three months ended June 30, 2018 and represented all of the ECT reporting unit’s goodwill.
