OTHER MATTERS	OTHER MATTERS We are a party to various claims, complaints and proceedings arising in the ordinary course of our continuing business operations including, but not limited to, those relating to commercial and employment claims, environmental matters, risk management matters (e.g., vehicle liability, workers’ compensation, etc.) and administrative assessments primarily associated with operating taxes. We have established loss provisions for matters in which losses are probable and can be reasonably estimated. For matters from continuing operations, we believe that the resolution of these claims, complaints and legal proceedings will not have a material effect on our consolidated financial statements. Our estimates regarding potential losses and materiality are based on our judgment and assessment of the claims utilizing currently available information. Although we will continue to reassess our reserves and estimates based on future developments, our objective assessment of the legal merits of such claims may not always be predictive of the outcome and actual results may vary from our current estimates.
