Decision-Making Body

These are items the company does not state in this document. We do not leave them blank, nor fill them in from other sources or by inference.

The reasons the company gives

The company's own explanation, not something inferred from the numbers.

Because sales and cost of sales had been recorded from fictitious circular transactions for which no advertising orders had been placed by advertisers, the Company corrected its prior-period financial results and, at the request of the Tokyo Stock Exchange, reported the circumstances and improvement measures. The Company identified insufficient knowledge of and sensitivity to risks in the advertising agency business, excessive reliance on individual employees, and inadequate subsidiary management, credit management and internal audits as causes of the issue.
