The Company has two reporting units, Energy Chemistry Technologies and Consumer and Industrial Chemistry Technologies, which had existing goodwill balances at December 31, 2017. 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. No impairments of goodwill were recognized in the Consumer and Industrial Chemistry Technologies reporting unit during the three and nine months ended September 30, 2018. During the three and nine months ended September 30, 2017, no impairments of goodwill were recognized.
