About the Awards for Excellence in Corporate Disclosure by SAAJ

The awards have been presented annually since fiscal 1995 with the aim of promoting and improving corporate information disclosure. The 2026 awards mark the 32nd edition. SAAJ’s Corporate Disclosure Study Group evaluates the quality, volume, and timing of corporate disclosure based on the following five criteria:

  • Attitude of management toward IR activities, the function of the IR department, and the company’s fundamental approach to IR activities
  • Disclosure through briefing sessions, interviews, presentation materials, and other channels
  • Fair disclosure
  • Disclosure of ESG-related information
  • Voluntary disclosure tailored to circumstances in the relevant industry

The awards evaluate the quality, volume, and timing of corporate information disclosure, including ESG-related information, as well as companies’ approaches to IR. They do not directly assess the relative merits of companies’ environmental performance.
