| Forward Looking Statements The foregoing discussion may include forward-looking statements for purposes of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements are based upon specific assumptions and are subject to uncertainties and factors relating to the company's operations and business environment, all of which are difficult to predict and many of which are beyond the control of the company. These uncertainties and factors could cause actual results of the company to differ materially from those expressed or implied in the forward-looking statements contained in the foregoing discussion. Such uncertainties and factors include: the speed and sustainability of price changes in cobalt and nickel; the potential for lower of cost or market write-downs of the carrying value of inventory necessitated by decreases in the market prices of cobalt and nickel; the availability of competitively priced supplies of raw materials, particularly cobalt and nickel; the risk that new or modified internal controls, implemented in response to the 2004 investigation by the audit committee of the Company's board of directors and the Company's examination of its internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act, are not effective and need to be improved; the demand for metal-based specialty chemicals and products in the Company's markets; the effect of fluctuations in currency exchange rates on the Company's international operations; the effect of non- currency risks of investing and conducting operations in foreign countries, including political, social, economic and regulatory factors; the effect of changes in domestic or international tax laws; the outcome of the previously announced SEC Division of Enforcement review of the investigation conducted by the Company's audit committee; the general level of global economic activity and demand for the Company's products; and the completion of the settlement of the shareholder derivative lawsuits filed against certain of the Company's former executives and certain of its current and former directors in a manner that is consistent with the Stipulation and Agreement of Settlement reached with the lead plaintiffs in such lawsuits. |
