Environmental Liabilities

When Avalon concludes that it is probable that a liability has been incurred with respect to a site, a provision is made in Avalon’s financial statements for Avalon’s best estimate of the liability based on management’s judgment and experience, information available from regulatory agencies, and the number, financial resources and relative degree of responsibility of other potentially responsible parties who are jointly and severally liable for remediation of that site, as well as, the typical allocation of costs among such parties. If a range of possible outcomes is estimated and no amount within the range appears to be a better estimate than any other, Avalon provides for the minimum amount within the range, in accordance with generally accepted accounting principles. The liability is recognized on an undiscounted basis. Avalon’s estimates are revised, as deemed necessary, as additional information becomes known. Although Avalon is not currently aware of any environmental liability, there can be no assurance that in the future an environmental liability will not occur.
