Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES |
5. | COMMITMENTS AND CONTINGENCIES
Environmental Matters We are involved, together with several other companies, in an environmental cleanup in the Village of Hartford, Illinois (the Village) and the adjacent shutdown refinery site, which we acquired as part of an acquisition in 2005. We have been conducting initial mitigation and cleanup with other companies pursuant to an administrative order issued by the U.S. Environmental Protection Agency (EPA). The U.S. EPA is seeking further cleanup obligations from us and other potentially responsible parties (PRPs) for the Village. In parallel with the Village cleanup, we are in litigation with the Illinois EPA and other PRPs relating to the remediation of the shutdown refinery site. In each of these matters, we have various defenses and rights for contribution from the other responsible parties. We have accrued for our own expected contribution obligations. However, because of the unpredictable nature of these cleanups and the methodology for allocation of liabilities, it is reasonably possible that we could incur a loss in a range of $0 to $200 million in excess of the amount of our accrual to ultimately resolve these matters. Factors underlying this estimated range are expected to change from time to time, and actual results may vary significantly from this estimate. Litigation Matters We are party to claims and legal proceedings arising in the ordinary course of business. We have not recorded a loss contingency liability with respect to some of these matters because we have determined that it is remote that a loss has been incurred. For other matters, we have recorded a loss contingency liability where we have determined that it is probable that a loss has been incurred and that the loss is reasonably estimable. These loss contingency liabilities are not material to our financial position. We re-evaluate and update our loss contingency liabilities as matters progress over time, and we believe that any changes to the recorded liabilities will not be material to our financial position, results of operations, or liquidity.
