Usage of XBRL in TD-net
Reference format of Earning Digest

• XBRL is used for inputting numerical data such as
  Earning Digests, Corrections, etc.
• If data are input into special disclosure
  software provided by TSE, both XBRL format and
  PDF format (disclosure material) data will be
  produced at the same time.
• Numerical data are accumulated as XBRL format in
  database

Future Challenges

• (Technical Issues)
• Improvement of the input form.
• How TSE will be involved in the reform of
  taxonomy.
• (System Issues)
• Scope of data and information which should be
  produced in XBRL format.
• Adopting XBRL format to legal disclosure in Japan.
