2 Regulation G The attached charts include Company information that does not conform to generally accepted accounting principles (GAAP). Management believes that an analysis of this data is meaningful to investors because it provides insight with respect to ongoing operating results of the Company and allows investors to better evaluate the financial results of the Company. These measures should not be viewed as an alternative to GAAP measures of performance. Furthermore, these measures may not be consistent with similar measures provided by other companies. This data should be read in conjunction with the Company’s first quarter earnings news release dated April 29, 2013, which has been furnished to the SEC on Form 8-K, and the Company’s Form 10-Q for the quarterly period ended March 31, 2013, which has been filed with the SEC. 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 materially 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.
