Basis Of Presentation [Abstract] |
Basis Of Presentation | In the opinion of management, the accompanying consolidated financial statements of Tredegar Corporation and its subsidiaries (“Tredegar,” “the Company,” “we,” “us” or “our”) contain all adjustments necessary to state fairly, in all material respects, Tredegar’s consolidated financial position as of September 30, 2017, the consolidated results of operations for the three and nine months ended September 30, 2017 and 2016, the consolidated cash flows for the nine months ended September 30, 2017 and 2016, and the consolidated changes in shareholders’ equity for the nine months ended September 30, 2017. All such adjustments, unless otherwise detailed in the notes to the consolidated interim financial statements, are deemed to be of a normal, recurring nature. The Company operates on a calendar fiscal year except for the Aluminum Extrusions segment, which operates on a 52/53-week fiscal year basis. As such, the fiscal third quarter for 2017 and 2016 for this segment references 13-week periods ended September 24, 2017 and September 25, 2016, respectively. The Company does not believe the impact of reporting the results of this segment as stated above is material to the consolidated financial results. The financial position data as of December 31, 2016 that is included herein was derived from the audited consolidated financial statements provided in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (“2016 Form 10-K”) but does not include all disclosures required by United States generally accepted accounting principles (“GAAP”). These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s 2016 Form 10-K. The results of operations for the three and nine months ended September 30, 2017, are not necessarily indicative of the results to be expected for the full year. Certain prior year balances have been reclassified to conform with current year presentation (see Note 13 for additional detail).
