Reasons for the above Revisions At the second quarter of FY 2005, overseas sales exceeded our previous forecast and that resulted in increases in both sales and profits. In addition, due to an increase in dividend income from our subsidiaries, etc., we predict that an ordinary income and current net income will exceed our previous forecast. We therefore revise the earnings forecast as above. * Cautionary Statement with Respect to Forward-Looking Statements This document contains "forward-looking statements" that are based on Advantest's current expectations, estimates and projections.
