     The accompanying unaudited condensed consolidated financial statements have been prepared by management in accordance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2004. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial information for the periods indicated, have been included. The results for the three-month period ended April 3, 2005 are not necessarily indicative of the results that may be expected for the year ending December 31, 2005.

     Property, Plant and Equipment

     Property, plant and equipment are recorded at cost. Significant improvements are capitalized, while maintenance and repair expenditures are charged to operations as incurred. The Company capitalizes interest cost as a component of construction in progress. In general, the straight-line method of depreciation is used for financial reporting purposes and accelerated methods are used for U.S. and certain foreign tax reporting purposes. The annual rates of depreciation are 3% - 6.67% for buildings, 6.67% - 12.5% for machinery and equipment, 8% - 12.5% for furniture and fixtures and 12.5% - 25% for computer equipment and software-related assets.

     Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management's estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual obligation to purchase products made using those assets. The Company's sales of precipitated calcium carbonate ("PCC") are predominantly pursuant to long-term contracts, initially ten years in length, with paper mills at which the Company operates satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. The Company also continues to supply PCC at three locations at which the PCC contract has expired and one location, representing one unit of PCC production, at which the host mill has provided notice to the Company of its plans to cancel the PCC supply contract upon its expiration in 2006. Failure of a PCC customer to renew an agreement or continue to purchase PCC from a Company facility could result in an impairment of assets charge or accelerated depreciation at such facility.

     Depletion of mineral reserves is determined on a unit-of-extraction basis for financial reporting purposes and on a percentage depletion basis for tax purposes.

     Mining costs associated with waste gravel and rock removal in excess of the expected average life of mine stripping ratio are deferred. These costs are charged to production on a unit-of-production basis when the ratio of waste to ore mined is less than the average life of mine stripping ratio.

     In December 2004, the FASB issued SFAS No. 123-R, "Share-Based Payments." This statement replaces Statement No. 123 and supercedes APB Opinion 25 covering a wide range of share-based compensation arrangements including share options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans. It will require companies to recognize the compensation costs relating to share-based payments to their employees in their financial statements. This statement will be effective for fiscal years beginning after June 15, 2005. The Company is in the process of analyzing the impact this new pronouncement will

have on its operations. In the interim, the Company will continue its proforma disclosure as required under SFAS No. 148, "Accounting for Stock-Based Compensation."

     The fair value of stock-based awards to employees was calculated using the Black-Scholes option-pricing model, modified for dividends, with the following weighted average assumptions:

     Pro forma net income and earnings per share reflecting compensation cost for the fair value of stock options were as follows:

     Basic earnings per share are based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share are based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all dilutive potential common shares outstanding. The following table sets forth the computation of basic and diluted earnings per share:
