NOTE 15 – COMMITMENTS AND CONTINGENCIES

Purchase Commitments

When market conditions warrant, the Company may enter into purchase commitments to secure the supply of certain commodities used in the manufacturing process of its products, such as aluminum, electricity, natural gas, and other raw materials. Prices under the Company’s aluminum contracts are based on a market index and regional premiums for processing, transportation, and alloy components, which are adjusted quarterly for purchases in the ensuing quarter. Certain purchase agreements include volume commitments; however, any excess commitments are generally negotiated with suppliers, and those that have occurred in the past have been carried over to future periods.

Contingencies

The Company is party to various legal and environmental proceedings incidental to its business. Certain claims, suits and complaints arising in the ordinary course of business have been filed or are pending against the Company. Based on facts now known, except as provided below, it believes all such matters are adequately provided for, covered by insurance, are without merit and/or involve such amounts that would not materially adversely affect the consolidated results of operations, cash flows or financial position.
