  1. Revenue does not include the consumption tax.
  2. JNFL has not created a consolidated financial statement, so the transition of major management indices related to the consolidated fiscal year is not included.
  3. Information regarding the share of profits(losses) of investments accounted for using the equity method has been omitted since the importance of the associated companies are not significant in terms of earnings standards and earned surplus standards.
  4. Information on diluted net income per share is not included because there are no dilutive shares.
  5. JNFL's shares are not listed, so the price-earnings ratio is not included.
