Goodwill And Intangible Assets Disclosure [Abstract] |
Purification Solutions Goodwill and Long-Lived Assets Impairment Charges | E. Purification Solutions Goodwill and Long-Lived Assets Impairment Charges During the second quarter of fiscal 2018, the Company recorded impairment charges relating to the goodwill and long-lived assets of the Purification Solutions reporting unit, and an associated deferred tax benefit, in the Consolidated Statement of Operations as follows:
|  | Three Months Ended March 31, 2018 |
|  | (In millions) |
Purification Solutions goodwill impairment charge |  | $ | 92 |
Purification Solutions long-lived assets impairment charge |  |  | 162 |
Provision (benefit) for income taxes |  |  | (30 | )
Impairment charges, after tax |  | $ | 224 |
In the second quarter of fiscal 2018, the Purification Solutions reporting unit experienced further share losses, lower customer demand and declining prices in the mercury removal and North America powdered activated carbon applications, which led the Company to reassess its previous estimates for expected growth in volumes, prices and margins in the reporting unit. The forecasted demand and profit margins in mercury removal applications were lowered reflecting further unit closures at coal-fired utility plants, lower usage levels of activated carbon and lower plant utilization levels for coal-fired utilities, as well as lower pricing due to industry overcapacity, among other factors. While development programs continue to progress, growth estimates in other environmental and specialty applications were also lowered, reflecting heightened competition and updated timelines to commercialize certain new products. Due to these revised forecasts, the Company performed the quantitative goodwill impairment test and determined that the estimated fair value of the Purification Solutions reporting unit was lower than the reporting unit's carrying value, resulting in a goodwill impairment charge of $92 million. In determining the fair value of the Purification Solutions reporting unit, the Company used an income approach (a discounted cash flow analysis) which incorporated significant estimates and assumptions related to future periods, including growth rates in environmental and specialty applications and pricing assumptions of activated carbon, among others. In addition, an estimate of the reporting unit’s weighted average cost of capital (“WACC”) was used to discount future estimated cash flows to their present value. The WACC was based upon externally available data considering market participants’ cost of equity and debt, optimal capital structure and risk factors specific to the Purification Solutions reporting unit. Prior to determining the goodwill impairment charge, the Company considered whether the assets of the reporting unit were recoverable. As a result of this assessment, the Company recorded an inventory reserve adjustment of $13 million and impairments to long lived assets of $162 million. The adjustment to inventory carrying value was determined based on reassessments of volumes, pricing, and margins described above and was recorded in Cost of sales in the Consolidated Statements of Operations. The impairment analysis to assess if definite-lived intangible assets and property, plant and equipment were recoverable was based on the estimated undiscounted cash flows of the reporting unit, and these cash flows were not sufficient to recover the carrying value of the long-lived assets over their remaining useful lives. Accordingly, the Company recorded impairment charges of $64 million and $98 million, to its definite-lived intangible assets and property, plant and equipment, respectively, in the quarter ended March 31, 2018 based on the lower of the carrying amount or fair value of the long-lived assets. The Company used the income approach to determine the fair value of the definite-lived intangible assets and the cost approach to determine the fair value of its property, plant and equipment. Cabot will continue to monitor for events or changes in business circumstances that may indicate that the remaining carrying value of the asset group may not be recoverable. The Company recorded a tax benefit related to the impairment charges of $30 million in the second quarter of fiscal 2018 which was subsequently reduced by $2 million in the third quarter of fiscal 2018 due to finalization of the impairment charges by tax jurisdiction.
