Business Combinations [Abstract]
Business Acquisition and Investments in Affiliates	Note 10 — Business Acquisition and Investments in Affiliates In the second quarter of 2016, we acquired a 10.3% interest in Oxford Performance Materials (“OPM”) for $15.0 million. OPM produces thermoplastic, carbon fiber reinforced 3D printed parts primarily for Commercial Aerospace and Space and Defense applications. In addition, if OPM achieves certain milestones within an 18 month period or at Hexcel’s discretion, the Company will invest an additional $10 million, increasing its investment in OPM to 16.1%. We account for this investment using the cost method. We also issued an 8% convertible secured promissory note to Luminati Aerospace LLC (“Luminati”), in the amount of $10 million. Luminati is an aerospace technology company focusing on research, development, testing, and manufacturing of next generation solar-electric unmanned aerial vehicles, or UAVs. The note matures in 2023 and the principal and interest are convertible to a 17.2% interest in Luminati. The note will convert upon Luminati achieving certain milestones or at Hexcel’s discretion. On January 5, 2016 the Company acquired the remaining 50% of Formax (UK) Limited (“Formax”) for $12 million of which $8.6 million was paid on closing and the remaining will be paid in installments over the next four years. The Company previously acquired a 50% interest in the privately-owned company in December 2014. Located in Leicester, U.K., Formax is a leading manufacturer of composite reinforcements, specializing in the production of lightweight carbon multi-axials and highly engineered glass fiber and aramid fiber fabrics. The total purchase price, net of cash acquired and including the 50% interest acquired in December 2014, was $22 million and the assumption of long-term debt of $8.2 million. The step acquisition was accounted for under the acquisition method of accounting with the Company treated as the acquiring entity. Accordingly, the consideration paid by the Company to complete the acquisition has been recorded to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of acquisition. The Company engaged a third party to assist with the valuation of assets including property plant and equipment and intangible assets. The fair value of the property, plant and equipment was based upon the assessed value of the land, which was determined to approximate fair value, as well as the income approach in determining the fair value of building improvements and equipment. The carrying values for current assets and liabilities were deemed to approximate their fair values due to the short-term nature of these assets and liabilities. The excess of the purchase price over the estimated fair value of the net assets acquired, including identifiable intangible assets, of $10.2 million was allocated to goodwill. The goodwill recognized is attributable to expected revenue synergies generated by the integration of our products and technologies with those of Formax, costs synergies resulting from the consolidation or elimination of certain functions, and intangible assets that do not qualify for separate recognition, such as the assembled workforce of Formax.
