Commitments and Contingencies

Contingencies. The company is subject to regulations regarding forest, harvest and manufacturing practices and is, from time to time, involved in various legal proceedings, including environmental and regulatory matters, incidental to its business. Reserves have been established for any probable losses.

Unrecorded Contingencies. Management currently believes that resolving other pending legal proceedings against the company, individually or in aggregate, will not have a material adverse impact on our financial position or results of operations. However, these matters are subject to inherent uncertainties and management’s view on these matters may change in the future. Were an unfavorable final outcome in one or multiple legal proceedings to occur, there exists the possibility of a material adverse impact on our financial position and the results of operations for the period in which any unfavorable outcome becomes reasonably estimable.
