But looming in the background is the fresh threat of a civil suit from Nissan and partner Mitsubishi. Nissan owns a controlling stake in Mitsubishi as part of the three-party auto alliance, and both companies jettisoned Ghosn as chairman after his arrest.
Nissan is conducting an internal investigation of possible misconduct linked to Ghosn. As the picture comes into focus, Nissan intends to seek redress, according to people familiar with the matter.
"After things are ironed out, we are going to claim damages," one person said.
People familiar with Nissan's probe claim the company has evidence of widespread financial misconduct by Ghosn. The accusations focus on issues such as payments for yacht club memberships, home renovations and surreptitious salaries, which Nissan claims violated company procedures.
Headlining the claims is the accusation that Ghosn received about €7.82 million ($8.9 million) in allegedly improper compensation last year from a Netherlands subsidiary jointly owned by Nissan and Mitsubishi.
That finding was an outgrowth of a joint investigation by Mitsubishi and Nissan. Mitsubishi CEO Osamu Masuko outlined the charges publicly Friday, Jan. 18, in Tokyo, saying that his company was consulting with Nissan, their lawyers and prosecutors about next steps.
They are weighing possible civil or criminal charges, a Mitsubishi lawyer said.
Nissan issued a separate news release concurring with the findings.
The entity in question, Nissan-Mitsubishi, or NMBV, was established as a 50-50 venture to reward employees at both companies who find synergies by giving them a share of the savings. But Nissan and Mitsubishi claim that Ghosn used the entity to authorize large payouts to himself.
The $8.9 million, which included a signing bonus and a salary, was allegedly paid without knowledge or the required consultation of the unit's other board members, Masuko and Nissan CEO Hiroto Saikawa. Neither of those men received any payment from NMBV, Nissan said.
