Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill Disclosure	Electronic Chemicals (“EC”) During the first quarter of 2023, while the criteria had not been met to classify the reporting unit as held for sale, the Company was exploring market interest in a potential sale of the EC reporting unit within what is now the Materials Solutions segment (the segment resulting from combining our prior Advanced Planarization Solutions and the Specialty Chemicals and Engineered Materials segments). In connection with the sale process, management determined that certain impairment indicators were present and evaluated intangible assets, long-lived assets and goodwill for impairment in connection with the quarter ending April 1, 2023. Long-lived assets, including finite-lived intangible assets The Company compared the estimated undiscounted future cash flows generated by the asset group to the carrying amount of the asset group for the reporting unit and determined that the undiscounted cash flows were expected to exceed the carrying value on a held and used basis, therefore no impairment was recorded on the long-lived asset or finite-lived intangible assets. The Company considered if the triggering event would cause a potential change to the useful life of the assets and determined no modification to the useful life of the assets was necessary. Goodwill The Company compared the reporting unit’s fair value to its carrying amount, including goodwill, as of April 1, 2023. As the reporting unit’s carrying amount, including goodwill, exceeded its fair value, the Company determined the goodwill was impaired and recorded an impairment of $88.9 million during the three months ended April 1, 2023 and an incremental impairment charge of $15.9 million was recorded as a result of certain purchase price adjustments during the three months ended September 30, 2023. The impairment is classified as goodwill impairment in the Company's consolidated statement of operations. The goodwill impairment is not tax deductible. The fair value of the reporting unit was determined using a market-based approach, which was aligned to the expected selling price. We consider this a Level 3 measurement in the fair value hierarchy. Following the end of our third quarter of fiscal year 2023, on October 2, 2023, we completed the sale of the EC reporting unit, which reported into the Materials Solutions segment. For more information, see Note 5. Other Business During the fourth quarter of 2023, the Company began the process to sell a small, industrial specialty chemicals business that reports within the MS segment. The related assets and liabilities of the business were classified as held-for-sale in the Company’s consolidated balance sheet at December 31, 2023. In connection with the sale process, management determined that certain impairment indicators were present and evaluated goodwill, intangible assets, and long-lived assets for impairment in connection with the quarter ending December 31, 2023. Goodwill The Company compared the reporting unit’s fair value to its carrying value, including goodwill, as of December 31, 2023. As the reporting unit’s carrying amount, including goodwill, exceeded its fair value, the Company determined the goodwill was impaired and recorded an impairment of $10.4 million during the year ended December 31, 2023. The impairment is classified as goodwill impairment in the Company’s consolidated statement of operations. The goodwill impairment is not deductible for tax purposes. The fair value of the reporting unit was determined using a market and income-based approach. We consider this a Level 3 measurement in the fair value hierarchy. Long-lived assets, including finite-lived intangible assets The Company compared the estimated undiscounted future cash flows generated by the asset group to the carrying amount of the asset group for the reporting unit and determined that the undiscounted cash flows did not exceed the carrying value. The Company next compared the reporting unit’s fair value to its carrying amount. As the reporting unit’s carrying amount exceeded its fair value, the Company determined long-lived assets were impaired and recorded an impairment of $30.5 million during the year ended December 31, 2023. The impairment is classified as Selling, general and administrative expense in the Company's consolidated statement of operations. The fair value of the reporting unit was determined using a market-based approach. We consider this a Level 3 measurement in the fair value hierarchy.
