Pure On April 7, 2017, the Company completed the acquisition of 100% of the outstanding shares of Columbia PhytoTechnology, LLC d/b/a PowderPure ("PowderPure"), a privately-held flavors company with facilities in North America. The acquisition was accounted for under the purchase method. PowderPure was acquired to expand expertise in, and product offerings of, clean label solutions within the Flavors business. The Company paid approximately $54.6 million , including $0.4 million of cash acquired for this acquisition, which was funded from existing resources. Additionally, the Company recorded an accrual of approximately $1.4 million representing the estimate at acquisition of additional contingent consideration payable to the former owners of PowderPure (the maximum earnout payable is $10 million upon satisfaction of certain performance metrics). The purchase price exceeded the preliminary fair value of existing net assets by approximately $48.0 million . The excess was allocated principally to identifiable intangible assets including approximately $27.5 million to proprietary technology, approximately $4.5 million to trade name, approximately $0.8 million to customer relationships, and approximately $15.2 million of goodwill which is deductible for tax purposes. Goodwill is the excess of the purchase price over the fair value of net assets acquired and represents the value the Company expects to achieve from its increased exposure to clean label products within the existing Flavors business. The intangible assets are being amortized over the following estimated useful lives: proprietary technology, 14 years; trade name, 14 years; and customer relationships, 2 years. The purchase price allocation was completed in the first quarter of 2018. No material adjustments have been made to the purchase price allocation since the preliminary valuation performed in the second quarter of 2017. The estimated amount of the contingent consideration payable was adjusted during the first quarter of 2018 and resulted in a decrease
