Forward-Looking Statements This presentation may contain forward-looking statements that are subject to certain risks and uncertainties that could cause actual results to differ ma terially from those projected in such statements. A major risk is that the Company’s demand is largely derived from the demand for its customers’ products, which subjects the Company to downturns in a customer’s business and unanticipated customer production shutdowns. Other major risks and uncertainties include, but are not limited to, significant increases in raw material costs, customer financial stability, worldwide economic and political conditions, foreign currency fluctuations, future terrorist attacks and other acts of violence. Other factors could also adversely affect us. Therefore, we caution you not to place undue reliance on our forward-looking statements.
