  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". We will give further consideration to the interpretation and the understanding of efficiency. The sales amounts of businesses for content presented in "Contributions to profits" in FY2018 are as follows:
    Mobile recycling equipment business

    2.3 billion yen

    Engine business

    199.7 billion yen
    (Total for intra-Group sales from the Engine Business Division)

Effects on Society *1

Environmental impact reduction effects
