Business Combination Disclosure [Text Block]

On June 30, 2016, Grace acquired the assets of BASF's polyolefin catalysts business for total consideration of $248.7 million, including an estimated $3.3 million holdback liability. The business will be included in the Specialty Catalysts operating segment of the Catalysts Technologies reportable segment. The acquisition purchase price has been preliminarily allocated to the tangible and identifiable intangible assets acquired based on their estimated fair values at the acquisition date in accordance with ASC 805 "Business Combinations." The excess of the purchase price over the fair value of the tangible and intangible assets acquired was recorded as goodwill. The goodwill recognized is attributable to the expected growth and operating synergies that Grace expects to realize from this acquisition. Goodwill generated from the acquisition will be deductible for income tax purposes over a period of 15 years. Due to the timing of the acquisition closing, Grace has not had adequate time to finalize the purchase price allocation. Adjustments to the allocation, if applicable, will be recorded in the 2016 third quarter.
