Environmental Matters Like other companies participating in similar lines of business, some of our subsidiaries are identified as a “potentially responsible party” under the federal Comprehensive Environmental Response, Compensation and Liability Act and similar local environmental statutes or are participating in the cost of certain clean-up efforts or other remedial actions relating to environmental matters. Our share of such costs to date, however, has not been material and management believes that these environmental proceedings will not have a material adverse effect on our consolidated financial condition or results of operations. See “Item 1 — Business — Environmental Matters,” in this Annual Report on Form 10-K. As permitted by Securities and Exchange Commission Rules and given the size of our operations, we have elected to adopt a quantitative disclosure threshold for environmental proceedings of $1.0 million. As of the date of this filing, we are not aware of any matters that exceed this threshold and meet the definition for disclosure.
