Supplemental Information Regarding Company Presentation at S.C. Bernstein Investor Conference on June 1, 2005

Return on Invested Capital (ROIC) is a measure of the return we earn on the capital invested in our businesses. Improving ROIC is a primary objective of our Global Business Plan. Our incentive compensation plans also contain ROIC objectives. We calculate ROIC on a rolling average four quarter basis using reported quarterly financial information. For 2004, ROIC has been calculated from GAAP financial data on as reported basis. The first three quarters of 2004 include the results of the Corporation's fine and technical papers business in consolidated operating profit as previously reported. For the fourth quarter of 2004, the results of these businesses are presented as discontinued operations as a result of their spin off. Therefore, fourth quarter GAAP basis reported consolidated operating profit reflects the results of continuing operations. We calculate ROIC as follows:

Where for each of the most recent four quarters:

A = total reported operating profit for the period

B = total reported nonoperating expense for the period

C = average effective tax rate for the period

D = total reported share of net income of equity companies for the period

E = average total assets for the period

F = average total current liabilities for the period

G = average debt payable within one year for the period
