Commitments and Contingencies

Raw Material Commitments

The Company’s primary raw materials are aluminum and steel coil. Because changes in aluminum and steel prices are generally passed through to customers, increases or decreases in aluminum and steel prices generally cause corresponding increases and decreases in reported net sales, causing fluctuations in reported revenues that are unrelated to the level of business activity. However, if the Company is unable to pass through aluminum and steel price increases to customers in the future, its business and results of operations could be materially adversely affected. Although the Company believes there is sufficient supply in the marketplace to competitively source all of its aluminum and steel needs without reliance on any particular supplier, any major disruption in the supply and/or price of aluminum and steel could have a material adverse effect on the Company’s business and financial condition.

To ensure a margin on specific customer orders, the Company may commit to purchase aluminum ingot or coil at a fixed market price for future delivery. These contracts are for normal purchases and sales, and therefore, are not required to be accounted for as derivatives.

Litigation

The Company is currently party to legal proceedings that have arisen in the ordinary course of business. The Company has and will continue to vigorously defend itself in these matters. It is the opinion of the Company’s management, based upon information available at this time, that the expected outcome of all matters to which the Company is currently a party would not reasonably be expected to have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

Environmental Matters

The Company’s operations are subject to U.S., Canadian, and European federal, state, and local environmental laws and regulations, including those concerning the management of pollution and hazardous substances.

In connection with the acquisition of the Company from Alumax Inc. (which was acquired by Aluminum Company of America in May 1998, and hereafter referred to as Alumax) on September 25, 1996, the Company was indemnified by Alumax for substantially all of its costs, if any, related to specifically identified environmental matters arising prior to the closing date of the acquisition during the period of time it was owned directly or indirectly by Alumax. Such indemnification includes costs that may ultimately be incurred to contribute to the remediation of eleven specified existing National Priorities List (NPL) sites for which the Company had been named a potentially responsible party under the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as of the closing date of the acquisition from Alumax, as well as certain potential costs for nine sites to which the Company may have sent waste for disposal. The Company does not believe that it has any significant probable liability for environmental claims. Further, the Company believes it to be unlikely that the Company would be required to bear environmental costs in excess of its pro rata share of such costs as a potentially responsible party at any site. Any receivable for recoveries under the indemnification would be recorded separately from the corresponding liability when the environmental claim and related recovery is determined to be probable. In addition, the Company establishes reserves for remedial measures required from time to time at its facilities. Management believes that the reasonably probable outcomes of these matters will not be material. The Company’s reserves, expenditures, and expenses for all environmental exposures were not significant as of any of the dates or for any of the periods presented.
