*1:Figures are rounded off to the nearest million yen.
*2:Komatsu used statements instead of numeral figures to describe the “Avoidance benefits of environmental risks” and the “Contribution to profits.” The company will further develop concepts and ways to understand effects in these categories. The sales amounts of businesses for content presented in “Contributions to profits” in FY2012 are as follows:

- Mobile recycling equipment business:
3.1 billion yen
- Engine business:
142.7 billion yen
(Total for intra-Group sales from the Engine Business Division)

Effects on Society *1

Environmental impact reduction effects Tangible benefits
- Environmental impact reduction resulting from on-site recycling methods
