Legal and Environmental Matters [Abstract] |
Legal and Environmental Matters | LEGAL AND ENVIRONMENTAL MATTERS Certain environmental matters and legal proceedings are discussed below. Environmental Matters LP maintains a reserve for undiscounted estimated environmental loss contingencies. This reserve is primarily for estimated future costs of remediation of hazardous or toxic substances at numerous sites currently or previously owned by the Company. LP’s estimates of its environmental loss contingencies are based on various assumptions and judgments, the specific nature of which varies in light of the particular facts and circumstances surrounding each environmental loss contingency. These estimates typically reflect assumptions and judgments as to the probable nature, magnitude and timing of required investigation, remediation and/or monitoring activities and the probable cost of these activities, and in some cases reflect assumptions and judgments as to the obligation or willingness and ability of third parties to bear a proportionate or allocated share of the cost of these activities. Due to the numerous uncertainties and variables associated with these assumptions and judgments, and the effects of changes in governmental regulation and environmental technologies, both the precision and reliability of the resulting estimates of the related contingencies are subject to substantial uncertainties. LP regularly monitors its estimated exposure to environmental loss contingencies and, as additional information becomes known, may change its estimates significantly. However, no estimate of the range of any such change can be made at this time. Other Proceedings LP and its subsidiaries are parties to other legal proceedings. Based on the information currently available, management believes that the resolution of such proceedings will not have a material adverse effect on the financial position, results of operations, cash flows or liquidity of LP.
