Business Combinations [Abstract]
Acquisitions	Acquisitions In January 2012, the Company purchased all of the shares of S&P Clever, for $58.1 million, subject to post-closing adjustments. S&P Clever manufactures and sells engineered materials to repair, strengthen and restore concrete, masonry and asphalt and has operations in Switzerland, Germany, Portugal, Poland, The Netherlands and Austria. Payments under the purchase agreement included cash payments of $57.5 million and contingent consideration of $0.6 million payable over a three-year period if sales goals are met. As a result of the acquisition, the Company has increased its presence in the infrastructure, commercial and industrial construction markets in Europe. The Company’s measurement of assets acquired and liabilities assumed included cash and cash equivalents of $6.8 million, other current assets of $10.8 million, non-current assets of $53.4 million, current liabilities of $12.6 million and non-current liabilities of $0.2 million. Included in non-current assets was goodwill of $19.3 million, which was assigned to the Europe segment and is not deductible for tax purposes, intangible assets of $20.5 million, the amortization of which is not deductible for tax purposes, and long-lived intangibles of $4.8 million related to IPR&D assets, which will be amortized when the Company markets the product for sale. The IPR&D assets at the time of acquisition were entering a field testing phase and were focused on new forms of strengthening structures. The weighted-average amortization period for the intangible assets is 9.8 years. In March 2012, the Company purchased substantially all of the assets of CarbonWrap Solutions, L.L.C. (“CarbonWrap”) for $5.5 million, subject to post-closing adjustments. CarbonWrap develops fiber-reinforced polymer products primarily for infrastructure and transportation projects. Payments under the purchase agreement totaled $5.3 million in cash and contingent consideration of $0.2 million paid on resolution of specified post-closing contingencies to the principal officer of CarbonWrap, who, on closing, was employed by the Company. The Company’s measurement included goodwill of $3.5 million, which was assigned to the North American segment and is deductible for tax purposes, and intangible assets of $1.7 million, which is subject to tax-deductible amortization. Net tangible assets consisting of accounts receivable, inventory, equipment and prepaid expenses accounted for the balance of the purchase price. In December 2013, the Company sold the CarbonWrap product line for $3.8 million and realized a gain of $1.4 million. See note 1 - Sale of Product Line. In December 2012, the Company completed a transaction with Keymark Enterprises LLC (“Keymark”). In 2011, the Company had purchased various software assets from Keymark and had engaged Keymark to perform certain software development for the Company, for which the Company had agreed to compensate Keymark at rates equal to a multiple of Keymark’s costs. In the transaction, the Company paid Keymark $9.1 million, hired thirty-nine Keymark employees to perform the development work that Keymark had previously been engaged to perform and purchased from Keymark various assets needed for that work. This transaction also included termination of the 2011 software development agreement and the Company is now entitled to certain software license revenue that was previously received by Keymark. The Company’s measurement of the assets acquired included goodwill of $5.9 million, which was assigned to the North American segment and is deductible for tax purposes, and intangibles of $3.0 million, which is subject to tax-deductible amortization. Equipment and prepaid expenses accounted for the balance of the purchase. The weighted-average amortization period for the intangible assets is 4.9 years. In February 2013, the Company purchased certain assets relating to the ShearBrace product line of Weyerhaeuser NR Company (“Weyerhaeuser”), a Washington corporation, for $5.3 million in cash. The ShearBrace is a line of pre-fabricated shearwalls that complement the Company’s Strong-Wall shearwall, and is sold throughout North America. The Company’s measurement of assets acquired included goodwill of $2.6 million, which was assigned to the North American segment, and intangible assets of $1.9 million, both of which are subject to tax-deductible amortization. Net tangible assets consisting of inventory and equipment accounted for the balance of the purchase price. The weighted-average amortization period for the intangible assets is 13.4 years. In November 2013, the Company purchased certain assets related to a connector product line from Bierbach GmbH & Co. KG (“Bierbach”), a Germany corporation, for $1.2 million in cash and a contingent liability of $0.8 million. Bierbach manufactured and sold a line of connectors, primarily in Germany. The Company’s measurement of assets acquired included goodwill of $0.5 million, which was assigned to the Europe segment, and intangible assets of $0.6 million, both of which are subject to tax-deductible amortization. Net tangible assets consisting of inventory and tool and dies accounted for the balance of the purchase price. At the end of 2014, the Company reduced the fair value of the contingent consideration liability from $0.8 million to $0.2 million due to a failure to retain Bierbach's historical customers and increased competition, which resulted in a $0.5 million gain that was reported in general and administrative expenses in the Consolidated Statements of Operations. The goodwill associated with Bierbach was fully impaired during 2014. (See Note 1 "Operations and Summary of Significant Accounting Policies - Goodwill Impairment Testing"). The weighted-average amortization period for the intangible assets is 9.7 years. Under the business combinations topic of the FASB ASC, the Company accounted for these acquisitions as business combinations and ascribed acquisition-date fair values to the acquired assets and assumed liabilities. Fair value of intangible assets was based on Level 3 inputs. The results of operations of the businesses acquired in 2013 are included in the Company’s consolidated results of operations since the date of the acquisition. Results of operations of acquired businesses for 2013 and for periods prior to 2013 were not material to the Company on an individual or aggregate basis, and accordingly, pro forma results of operations have not been presented.
