The arrest of Carlos Ghosn, chairman of Nissan and a board member at Mitsubishi, has also thrown into question the future of the two companies' global alliance with French automaker Renault. But analysts say that's not likely.
Ghosn was arrested Monday amid allegations of financial misconduct, sending shares of the Japanese automakers on a downward spiral on Tuesday.
Nissan said in a statement Monday that "over many years," Ghosn and board director, Greg Kelly, had been under-reporting compensation amounts to the Tokyo Stock Exchange securities report. According to Reuters, Japanese media said Ghosn had reported about 10 billion yen ($88.9 million) of annual compensation as about 5 billion yen for several years.
Nissan Chief Executive Hiroto Saikawa, said at a Monday press conference that both men had been arrested and he was planning to propose to the board on Thursday to remove them from their roles. Mitsubishi also said that it would seek to remove Ghosn, who sits on its board of directors, from his current position at the company.
