Nissan Motor's former chairman Carlos Ghosn reportedly received compensation of more than nine million dollars from an affiliated company without the knowledge of other board members.
Sources say an in-house probe by Nissan revealed that Ghosn allegedly received the money in 2018 as compensation from Nissan-Mitsubishi B.V. in Holland.
Nissan President Hiroto Saikawa and Mitsubishi Motors CEO Osamu Masuko are board members of the holding company, but they were reportedly not notified of the payment.
The sources say neither Saikawa nor Masuko received similar payments from the Dutch firm.
They say the in-house probe revealed that one of Renault's nine executives also received unreported compensation from another holding company, Renault-Nissan B.V.
Nissan and Mitsubishi are considering disclosing the findings of the investigation when it is complete.
