To whom it may concern

Dear Sir

I sincerely apologize for causing all of you a great nuisance and worry by a problem of our inappropriate accounting.
For Nippon Carbide Industries Co., Inc. which was a parent company today (on March 9), there was a notice of chomotome of publication measures and the improvement report from the Tokyo Stock Exchange.

I will hope that I have understanding and your guidance and encouragement as I carry out preventive measures against recurrences with a parent company and will make every possible effort for thorough compliance and recovery of the trust in future.
