This press release contains forward-looking statements that involve risks and uncertainties within the meaning of the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those expected as a result of a variety of factors, such as: (i) the volatility of resin pricing, (ii) the ability of the Company to pass through raw material cost increases to its customers, (iii) maintaining a stable level of housing starts, telecommunications infrastructure spending, consumer confidence and general construction trends, (iv) the continued availability and reasonable terms of bank financing and (v) any adverse change in the recovery trend of the country's general economic condition affecting the markets for the Company's products. Because forward-looking statements are based on a number of beliefs, estimates and assumptions by management that could ultimately prove to be inaccurate, there is no assurance that any forward-looking statement will prove to be accurate.
