As provided by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the Registrant cautions that statements in this Form 12b-25 relating to matters that are not historical facts including, but not limited to, statements found in Part III - "Narrative" and this Part IV - "Other Information," are forward-looking statements that represent management's belief and assumptions based on currently available information. Forward-looking statements can be identified by the use of words such as "believes," "intends," "may," "should," "could," "anticipates," "expected," or comparable terminology, or by discussions of strategies or trends. Although the Registrant believes the expectations reflected in such forward-looking statements are reasonable, it cannot give any assurances that these expectations will prove to be correct. Such statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such forward-looking statements. While it is not possible to identify all factors, the Registrant continues to face many risks and uncertainties. Among the factors that could cause actual future results to differ materially are the risks and uncertainties discussed in this filing and those described from time to time in the Registrant's other filings with the Securities and Exchange Commission including, but not limited to: o Future supply and demand for the Company's products, o The extent of the dependence of certain of the Company's businesses on certain market sectors, o The cyclicality of certain of the Company's businesses, o The impact of certain long-term contracts on certain of the Company's businesses, o Customer inventory levels, o Changes in raw material and other operating costs, o The possibility of labor disruptions, o General global economic and political conditions, o Competitive products and substitute products, o Customer and competitor strategies, o The impact of pricing and production decisions, o Competitive technology positions, o The introduction of trade barriers, o Fluctuations in currency exchange rates, o Operating interruptions, o The ability to implement headcount reductions in certain operations in a cost effective manner within the constraints of non-U.S. governmental regulations, and the timing and amount of any such cost savings realized, o The ability of the Company to renew or refinance credit facilities, o Uncertainties associated with new product development, o The ultimate outcome of income tax audits, tax settlement initiatives or other tax matters, o The ultimate ability to utilize income tax attributes, the benefit of which has been recognized under the "more-likely-than-not" recognition criteria, o The ultimate ability to timely complete the assessment of the Company's internal control over financial reporting, o Environmental matters, o Government laws and regulations and possible changes therein, o The ultimate resolution of pending litigation, and o Possible future litigation. Should one or more of these risks materialize (or the consequences of such a development worsen), or should the underlying assumptions prove incorrect, actual results could differ materially from those forecasted or expected. The Registrant disclaims any intention or obligation to update or revise any forward-looking statement whether as a result of changes in information, future events or otherwise.
