Nissan Motor Co’s shares fell more than six percent on Tuesday as Chairman Carlos Ghosn’s arrest a day earlier sent shockwaves through the business world and threw into doubt the future of Japan’s No.2 automaker and its global alliance.
Nissan said on Monday an internal investigation triggered by a tip-off from a whistleblower had revealed that Ghosn engaged in wrongdoing including personal use of company money and under-reporting for years how much he was earning. He was arrested and would be fired from Nissan’s board this week, it said.
Ghosn is also chairman and chief executive of Nissan’s French partner, Renault, and chairman of Japan’s Mitsubishi Motors Corp, the third partner in the alliance.
Ousting Ghosn will pose questions about an alliance that he personally shaped and had pledged to consolidate with a deeper tie-up, before eventually stepping back from its operational leadership.
It also brings into focus the future of Nissan – the biggest partner in the alliance – at a time it is seeing falling profits due to weak U.S. sales and is facing heightened competition from rivals who are investing heavily in new growth areas like internet connected cars and self-driving vehicles.
Ghosn’s alleged improprieties also raise questions over governance at the alliance in which the three partners’ boards are all chaired by a single executive.
Speaking at a late-night news conference on Monday, Nissan CEO Hiroto Saikawa conceded that too much power had been concentrated on Ghosn, and that the implications of his stewardship of both Renault and Nissan had gone unquestioned since 2005.
Prosecutors said in a statement that Ghosn and Representative Director Greg Kelly conspired to understate Ghosn’s compensation over five years starting in fiscal 2010 as being about half of the actual 9.998 billion yen ($88.9 million).
Ghosn joined Nissan in 1999 and became its CEO in 2001. He remained in that post until last year and had received 9.2 million euros ($10.53 million) in pay for the final year as CEO.
“By under-reporting his corporate salary, he basically deprived Nissan’s shareholders of opportunities to judge if the amount of his salary was appropriate,” Toru Ibayashi, executive director of Wealth Management at UBS Securities Japan, said of Nissan’s allegations.
Japanese public broadcaster NHK reported Nissan paid billions of yen for the purchase and renovation of homes for Ghosn in Rio de Janeiro, Beirut, Paris and Amsterdam, citing unnamed sources.
The properties had no business purpose and were not listed as benefits in filings to the Tokyo bourse, NHK said. CEO Saikawa declined on Monday to discuss specifics on Ghosn’s personal use of company money.
Nissan spent 2 billion yen on homes for Ghosn in Rio and Beirut via a Dutch subsidiary, with Kelly overseeing the transaction, the Nikkei newspaper reported, citing unnamed sources.
There has been no comment from Ghosn or Kelly on the allegations and Reuters could not contact them for comment.
In a sign of the broader political fallout, Hitoshi Kawaguchi, Nissan senior vice president handling government relations, met with Japan’s top government spokesman on Tuesday, telling media he had requested good relations between Japan and France be maintained.
The Asahi newspaper cited unnamed sources as saying a company employee gave prosecutors information on Ghosn in return for lighter treatment, the second instance of a plea deal in Japan – a system introduced in June.
Nissan shares fell to a two-year low of 940 yen and were later trading down five percent at 955 yen.

Shares of Mitsubishi, which also said on Monday it would remove Ghosn as its chairman, slid by about 6 percent. Renault shares lost 8.4 percent on Monday.
Ghosn’s downfall was unlikely to lead to a sharp fall in car sales, capping the downside for Nissan shares, said Fujio Ando, adviser at Chibagin Securities.
“The fact that the case came to light because of a whistleblower is also positive on the whole, in terms of corporate governance. If this had been revealed by outsiders, that would have been a different story,” he said.
