The value of a company will be determined by the trust of its stakeholders and such trust can only be gained when the firm's top executives take the initiative for information disclosure, Masahiro Sakane, chairman of Komatsu Ltd., told the Dec. 19 symposium.

Communication holds the key to better cooperation among divisions within a company, which contrary to the widespread view is poor at many Japanese firms, Sakane said in his keynote speech titled, "Management reform at Komatsu and communication."

Sakane defined corporate value as "the aggregate degree of trust a company receives from society and its stakeholders," including shareholders, clients, investors, sales agents and employees.
