Acquisitions Acquisition of Sierra Monitor Corporation On May 20, 2019, we acquired 100% of the common stock in Sierra Monitor Corporation ("SMC") in an all-cash transaction valued at $33.2 million , net of cash acquired. Additionally, we converted outstanding stock options and restricted stock units into MSA stock options and restricted stock units which resulted in additional goodwill of approximately $0.9 million based on the fair value of the awards identified as transaction consideration. Based in Milpitas, California, in the heart of Silicon Valley, SMC is a leading provider of fixed gas and flame detection instruments and Industrial Internet of Things solutions that connect and help protect high-value infrastructure assets. The acquisition enables MSA to accelerate its strategy to enhance worker safety and accountability through the use of cloud technology and wireless connectivity; a key focus of the Company's recently established Safety io TM subsidiary. MSA launched Safety io in 2018, primarily to leverage the capabilities of its portable gas detection portfolio as it relates to cloud connectivity. The transaction was funded through borrowings on our unsecured senior revolving credit facility. SMC operating results are included in our unaudited condensed consolidated financial statements from the acquisition date as part of the Americas reportable segment. The acquisition qualifies as a business combination and will be accounted for using the acquisition method of accounting. The following table summarizes the fair values of the SMC assets acquired and liabilities assumed at the date of acquisition: (In millions) May 20, 2019 Current assets (including cash of $2.1 million) $ 10.5 Property, plant and equipment and other noncurrent assets 1.3 Customer relationships 9.6 Acquired technology 1.4 Goodwill 19.8 Total assets acquired 42.6 Total liabilities assumed 6.4 Net assets acquired $ 36.2 The amounts in the table above are subject to change upon completion of the valuation of the assets acquired and liabilities assumed. This valuation is expected to be completed by mid-2020. Assets acquired and liabilities assumed in connection with the acquisition have been recorded at their fair values. Fair values were determined by management, based, in part on an independent valuation performed by a third party valuation specialist. The valuation methods used to determine the fair value of intangible assets included the relief from royalty method for technology related intangible assets; the excess earnings approach for customer relationships using customer inputs and contributory charges; and the cost method for assembled workforce which is included in goodwill. A number of significant assumptions and estimates were involved in the application of these valuation methods, including sales volumes and prices, royalty rates, costs to produce, tax rates, capital spending, discount rates, and working capital changes. Cash flow forecasts were generally based on SMC pre-acquisition forecasts coupled with estimated MSA sales synergies. Identifiable intangible assets with finite lives are subject to amortization over their estimated useful lives. The customer relationships acquired in the SMC transaction will be amortized over a period of 10 years and the technology will be amortized over 5 years . Estimated future amortization expense related to the identifiable intangible assets is approximately $0.6 million for the remainder of 2019, $1.2 million in each of the next four years 2020 through 2023 and $5.3 million thereafter. The step up to fair value of acquired inventory as part of the purchase price allocation totaled $1.6 million which will be amortized over six months . Goodwill is calculated as the excess of the purchase price over the fair value of net assets acquired and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Among the factors that contributed to a purchase price in excess of the fair value of the net tangible and intangible assets acquired were the acquisition of an assembled workforce, the expected synergies and other benefits that we believe will result from combining the operations of SMC with our operations. Goodwill of $19.8 million related to the SMC acquisition has been recorded in the Americas reportable segment and is non-deductible for tax purposes. Our results for the six months ended June 30, 2019, include strategic transaction costs of approximately $2 million , including costs related to the acquisition of SMC. Our results for the six months ended June 30, 2018, include an immaterial amount of strategic transaction costs. These costs are reported in selling, general and administrative expenses. The operating results of the SMC acquisition have been included in our unaudited condensed consolidated financial statements from the acquisition date through June 30, 2019. Our results for the six months ended June 30, 2019, include SMC sales and net loss of $2.6 million and $1.5 million , respectively.
