Despite equipment trouble at smelting facilities in Indonesia, growth in the North American
Cement Business and ongoing yen depreciation drove operating profit higher. Ordinary income
declined slightly on weak mining profits. Net income increased substantially mainly due to a gainon sales of shares of an affiliate.

Comparison
with previousforecast(Billions of yen)

Factoring in lower sales of cement and cemented carbide products in the Chinese
market in addition to decrease in the assumed copper price, operating profit andordinary income were revised lower. On the other hand, net income remains
unchanged due to a decrease in corporate income taxes and other factors. (The fullyear dividend forecast remains unchanged at ¥10 per share.)
