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 & Defense, Engineered Components, Cequent Asia Pacific Europe Africa ("Cequent APEA") and Cequent Americas. The Company renamed its former "Cequent Asia Pacific" reportable segment "Cequent APEA" effective in the second quarter of 2013 following the Company's recent acquisitions to more appropriately reflect the expanding geography covered by the businesses in this reportable segment. See Note 14, "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 2012 Annual Report on Form 10-K.
