NOTE 2  BUSINESS COMBINATIONS On December 31, 2018 , the Company completed its acquisition (the Acquisition) of EMD Millipore Corporations flow cytometry portfolio for $75 million , consisting of approximately $69.9 million paid under a Share and Asset Purchase Agreement (the Purchase Agreement) and approximately $5.1 million in committed inventory purchases, both of which are subject to adjustment. The Company financed the acquisition with cash on hand. Luminex acquired 100% of the shares and equity of Amnis Corporation, a Washington Corporation (Amnis), a wholly owned subsidiary of EMD Millipore Corporation, a Massachusetts corporation (itself an affiliate of Merck KgaA), and certain other assets owned by other affiliates of Merck KgaA (MilliporeSigma). The Acquisition expands Luminexs existing offering of flow-based detection systems, which is centered around its innovative xMAP  multiplexing technology, with more than 15,000 xMAP systems sold worldwide. MilliporeSigmas flow cytometry portfolio includes Amnis, a family of imaging flow cytometry products for cell-based analysis, as well as their Guava and Muse portfolio of products, which are economical systems based on microcapillary technologies. The purchase price was in excess of the fair value of the net assets acquired and, as a result, the Company recorded goodwill. A portion of the goodwill is deductible for tax purposes. The Company recorded approximately $2.7 million of acquisition-related costs during fiscal 2018. The impact of the Acquisition on our liquidity is more fully described under Liquidity and Capital Resources. The following table summarizes the preliminary estimated fair values of assets acquired and liabilities assumed in connection with the Acquisition at December 31, 2018 (in thousands): Net tangible assets assumed as of December 31, 2018 $ 8,181 Intangible assets subject to amortization 33,500 Deferred tax liabilities (4,433 ) Goodwill 32,646 Total purchase price $ 69,894 The Company is in the process of obtaining third-party valuations of certain intangible assets, performing a reconciliation of the assets and liabilities purchased with EMD Millipore Corporation and finalizing the calculations of the deferred tax assets and liabilities related to the Acquisition; thus the provisional measurement of net tangible assets assumed, intangible assets, deferred tax assets and liabilities and goodwill are subject to change. If information that existed prior to December 31, 2018 becomes available which would indicate adjustments are required to the purchase price allocation, such adjustments will be included in the purchase price allocations retrospectively through revisions to the net tangible assets assumed, fair values of the intangible assets, deferred tax assets and liabilities and resulting goodwill recorded. Unaudited Pro forma Financial Information The fourth quarter 2018 results of operations of business acquired in connection with the Acquisition are not included in our consolidated statements of comprehensive income for the three and twelve months ended December 31, 2018 as the Acquisition closed on December 31, 2018, but the financial position of the Acquisition is included in our consolidated balance sheet as of December 31, 2018. The unaudited pro forma financial information set forth below assumes that the Acquisition had been completed at the beginning of 2017 and includes the effect of estimated amortization of acquired identifiable intangible assets, removal of Acquisition costs and the impact of preliminary estimated purchase accounting adjustments, tax and inventory valuation adjustments.
