The statement added that Mr. Ghosn had “acted at all times with the full authority of the board and its shareholders, and his paramount goal was achieving value for Nissan’s shareholders.”
Nissan created the panel in December as an independent group tasked with delivering recommendations for improving the company’s organization and oversight. Three of its seven members serve as the board’s independent directors, including two who were appointed last summer, before Mr. Ghosn’s arrest but after the behavior described in the prosecutor’s charges against him and Mr. Kelly.
The other four members were experts on Japanese corporate governance, a former judge, and a onetime head of Japan’s largest business association.
The report revealed details of Nissan’s internal investigation into Mr. Ghosn and Mr. Kelly, including the claim that an unspecified individual had falsified corporate documents in an effort to conceal the details of Mr. Ghosn’s compensation.
While conceding that Nissan’s current chief executive, Hiroto Saikawa, a board member, had signed off on at least some of Mr. Ghosn’s compensation, the report argued that Mr. Ghosn’s machinations had made it impossible for the board to exert proper oversight of his behavior.
The report said that until the appointment of the two new independent directors, typical board meetings chaired by Mr. Ghosn had lasted no longer than 20 minutes, “creating an atmosphere where it was not possible to ask questions about or give opinions on the agenda at the meetings.”
The committee emphasized at a news conference after the report’s release that it was not making any legal judgment but said it had found “facts sufficient to suspect violations of laws and regulations.”
