NOTE 9:

Environmental

Consistent with our accounting policy for environmental remediation costs, we expensed $0.1 million for the three months ended June 30, 2011 and 2010 and $0.1 million and $1.5 million for the six months ended June 30, 2011 and 2010, respectively, for environmental remediation obligations. The accrued environmental liability reflected in our consolidated balance sheets was $23.4 million and $26.2 million at June 30, 2011 and December 31, 2010, respectively, of which $17.8 million and $20.4 million, respectively, were classified as other long-term liabilities. Costs of future expenditures for environmental remediation that are expected to be incurred over the next several years are not discounted to their present value.
