Forward-looking Statement and Additional Information This presentation contains historical information and forward-looking statements within the meaning of the federal securities laws. As a general matter, forward-looking statements are those focused upon future plans, objectives or performance as opposed to historical items and include statements of anticipated events or trends and expectations and beliefs relating to matters not historical in nature. Such forward- looking statements involve known and unknown risks and are subject to uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control. These uncertainties and factors could cause our actual results to differ materially from those matters expressed in or implied by such forward-looking statements. We do not undertake any obligation to update any forward-looking statements to reflect the impact of circumstances or events that may arise after the date of such forward-looking statements. We believe that the following factors, among others, could affect our future performance and cause actual results to differ materially from those expressed or implied by forward-looking statements made in this presentation: business conditions in the plastics, transportation, marine and commercial product industries; federal and state regulations (including engine emission regulations); general economic, social and political environments in the countries in which we operate; safety and security conditions in Mexico; dependence upon two major customers as the primary source of our sales revenues; our efforts to expand our customer base; the actions of competitors, customers, and suppliers; failure of our suppliers to perform their obligations; the availability of raw materials; inflationary pressures; new technologies; regulatory matters; labor relations; our loss or inability to attract and retain key personnel; federal, state and local environmental laws and regulations; the availability of capital; our ability to provide on-time delivery to customers, which may require additional shipping expenses to ensure on- time delivery or otherwise result in late fees; risk of cancellation or rescheduling of orders; management’s decision to pursue new products or businesses which involve additional costs, risks or capital expenditures; and other risks identified from time-to-time in our public documents on file with the Securities and Exchange Commission (“SEC”), including those described in our Annual Report on Form 10-K for the year ended December 31, 2012 as well as our other filings with the SEC. This presentation includes references to earnings before interest, taxes, depreciation and amortization (“EBITDA”), which is a non-GAAP financial measure. EBITDA is reconciled to net income, its most directly comparable GAAP measure, in the financial table included in the Appendix to this presentation. We believe that this additional information and the reconciliation we provide may be useful to help evaluate our operations. This information supplements our results as reported in accordance with GAAP and should not be viewed in isolation from, or as a substitute for, our GAAP-results.
