The acquisition is complementary to Grace's existing specialty catalysts business and strengthens Grace's commercial relationships, catalysts technology portfolio, and manufacturing network. The acquisition purchase price has been allocated to the tangible and identifiable intangible assets and liabilities 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 purchase price allocation has been finalized, and during the measurement period, Grace recorded adjustments related to deferred taxes, working capital, and intangible assets. The goodwill recognized was $140.6 million and is supported by the expected growth and operating synergies that Grace expects to realize from this acquisition. The full amount of goodwill generated will be deductible for U.S. income tax purposes. The Consolidated Statement of Operations for the three months ended March 31, 2019, includes approximately $25 million of sales attributable to this acquisition. Disclosure of earnings attributable to this acquisition is not practicable due to the integration of operations into Grace’s existing business.
