Commitments and Contingencies | Note 3 – Commitments and Contingencies We are involved in various legal claims and proceedings in the normal course of operations. We believe the outcome of these matters will not have a material adverse effect on our consolidated financial position, results of operations or liquidity. Notes 7, 9, 10, 11, 12, 14, and 15 provide additional information regarding certain of our significant long-term commitments and certain significant contingencies we have provided for in the accompanying consolidated condensed financial statements. Our products are under warranty against defects in material and workmanship for periods ranging from two to five years. We estimate our warranty accrual using historical trends and believe that these trends are the most reliable method by which we can estimate our warranty liability.
