At September 30, 2010, the Company has accrued approximately $4,300 as probable costs and it is reasonably possible that additional losses could range up to $12,900 for these matters. For certain matters, the Company is unable to estimate possible losses. The Company believes that damages or settlements, if any, recovered by plaintiffs in such claims or actions will not have a material adverse effect on the Company's results of operations, financial position or cash flows.   The Company enters into agreements for the provision of services to water and wastewater facilities for the United States military, municipalities and other customers. The Company's military services agreements expire between 2051 and 2060 and have remaining performance commitments as measured by estimated remaining contract revenue of $2,104,000 at September 30, 2010. The Company's Operations and Maintenance agreements with municipalities and other customers expire between 2010 and 2048 and have remaining performance commitments as measured by estimated remaining contract revenue of $1,243,000 at September 30, 2010. Some of the Company's long-term contracts to operate and maintain a municipality's, federal government's or other party's water or wastewater treatment and delivery facilities include responsibility for certain major maintenance for some of those facilities, in exchange for an annual fee. Unless specifically required to perform certain maintenance activities, the maintenance costs are recognized when the maintenance is performed. </div> Note 9: Commitments and Contingencies The Company is also routinely involved in legal actions incident to the normal conduct of its business.
