Contingencies [Abstract] |
Contingencies | 4. Contingencies The Company is party to various legal proceedings and claims related to its normal business operations. In the opinion of management, the Company has substantial and meritorious defenses for these claims and proceedings in which it is a defendant, and believes these matters will be ultimately resolved without a material adverse effect on the consolidated financial position, results of operations or liquidity of the Company. The aggregate provision for losses related to contingencies arising in the ordinary course of business was not material to operating results for any year presented. During the fourth quarter of 2010, the Company was contacted by the State of Illinois regarding potential ground contamination at our plant in Wheeling, Illinois. The Company signed up with a voluntary remediation program in Illinois and has engaged an environmental clean-up company to perform testing and develop a remediation plan, if needed. No estimate for the cost of remediation was available when this Form 10-K was filed with the SEC. Approximately 37% of the total workforce is subject to negotiated union contracts, and approximately 15% of the total workforce is covered by such agreements that expire during 2012.
