TOKYO (Reuters) - An internal probe at Nissan Motor Co has determined that Chief Executive Hiroto Saikawa and multiple other executives had received excess stock performance-related compensation in violation of company rules, a source said on Thursday.

The source, who has direct knowledge of the matter, said the misconduct was disclosed at a meeting of Nissan’s audit committee a day earlier. Nissan’s board is set to meet later this month and consider disciplinary action, the source said, declining to be identified because the information is not public.
