3. BUSINESS COMBINATION ? On April 23, 2018, we acquired 100% of the outstanding equity interests of Demilec (USA) Inc. and Demilec Inc. (collectively, Demilec) for approximately $353 million, including working capital adjustments, in an all-cash transaction (Demilec Acquisition), which was funded from our previous $650 million senior secured revolving credit facility (the Prior Credit Facility) and our U.S. accounts receivable securitization program (U.S. A/R Program). Demilec is a leading North American manufacturer and distributor of spray polyurethane foam formulations for residential and commercial applications. The acquired business was integrated into our Polyurethanes segment. Transaction costs charged to expense related to this acquisition were approximately $1 million for the six months ended June 30, 2018. The Demilec Acquisition was aligned with our stated strategy to grow our downstream polyurethanes business and leverage our global platform to expand Demilecs portfolio of spray polyurethane foam formulations into international markets. ? We have accounted for the Demilec Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions): ? ? ? ? ? Fair value of assets acquired and liabilities assumed: ? ? ? Cash paid for the Demilec Acquisition in Q2 2018 ? $ 357 Purchase price adjustment received in Q3 2018 ? ? (4) Net acquisition cost ? $ 353 ? ? ? ?

(16) Accrued liabilities ? ? (3) Deferred income taxes ? ? (22) Other noncurrent liabilities ? ?  Total fair value of net assets acquired ? $ 353 ? As a result of a preliminary valuation of the assets and liabilities, reallocations were made during 2018 in certain property, plant and equipment, intangible asset, goodwill and deferred tax balances. As a result of the finalization of the valuation of the assets and liabilities, additional reallocations were made in 2019 in certain goodwill, other noncurrent liabilities and deferred tax balances. Intangible assets acquired consist primarily of trademarks, trade secrets and customer relationships, all of which are being amortized over 15 years. We have assigned any excess of the acquisition cost of the fair values to goodwill. During the third quarter of 2018, we received $4 million related to the settlement of certain purchase price adjustments. The goodwill recognized is attributable primarily to projected future profitable growth, penetration into downstream markets, and synergies. ?
