Commitments and Contingencies
Note 15 — Commitments and Contingencies
Litigation
     We are involved in various legal proceedings that arise from time to time in the ordinary course of doing business and believe that adequate reserves have been established for any probable losses. We do not believe that the outcome of any of these proceedings should have a significant adverse effect on our financial position, long-term results of operations or cash flows. It is possible; however, that charges related to these matters could be significant to our results or cash flows in any one accounting period.
Environmental
     Environmental remediation liabilities arise from time to time in the ordinary course of doing business, and we believe we have established adequate reserves for any probable losses. We own 288 acres near Antioch, California, portions of which were sites of a former Temple-Inland paper manufacturing operation that are in remediation. We estimate the cost to complete remediation activities will be approximately $1,940,000, which is included in other accrued expenses and will likely be paid in 2011 or 2012. Our estimate requires us to make assumptions regarding the scope of required remediation, the effectiveness of planned remediation activities, and approvals by regulatory authorities. Our estimate is subject to revision as new information becomes available.
