Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation TriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, is a global manufacturer and distributor of products for commercial, industrial and consumer markets. The Company is principally engaged in the following reportable segments with diverse products and market channels: Packaging, Energy, Aerospace, Engineered Components, Cequent Asia Pacific Europe Africa ("Cequent APEA") and Cequent Americas. See Note 10, "Segment Information," for further information on each of the Company's reportable segments. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries and, in the opinion of management, contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. Results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying consolidated financial statements and notes thereto should be read in conjunction with the Company's 2014 Annual Report on Form 10-K. On December 8, 2014, the Company announced that its Board of Directors had approved a plan to pursue a separation of its Cequent businesses through a spin-off, creating a new independent publicly traded company, Horizon Global Corporation("Horizon"). The transaction is expected to be tax-free to shareholders and is targeted to be completed by mid 2015, subject to certain conditions including, among others, approval of the Company's Board of Directors, declaration of the effectiveness of the registration statement on Form S-1 by the SEC and receipt of an opinion from counsel regarding the tax free nature of the spin-off. One time transaction costs in connection with the separation of the two companies, including dedicated internal and third party amounts, are expected to be approximately $30 million.
