Corporate Disclosure
The objective of the Corporate Disclosure Study Group is to promote the quality and fairness of corporate disclosure from the viewpoint of securities analysts. To achieve this goal, the Group has implemented a corporate disclosure evaluation and award system since 1995. The Group, comprising representatives from 20 sub-groups (18 industries, emerging markets, and disclosure to individual investors), formulates corporate disclosure review criteria (score sheets) for each industry / area specific features. The criteria attach greater importance to voluntary and positive disclosure rather than mandatory disclosure.
