Renault SA has alerted French prosecutors to payments made to a Renault-Nissan business partner in Oman under former Chief Executive Carlos Ghosn, according to three sources.

This follows an internal investigation by the French carmaker after Ghosn’s November arrest in Tokyo for suspected financial misconduct at alliance partner Nissan Motor Co.

Renault has established it paid out millions of euros described as dealer incentives to Omani distributor Suhail Bahwan Automobiles (SBA) over five years from around 2011, said the sources, who were briefed on the findings.

Nissan previously found that its own regional subsidiary made questionable payments of more than $30 million to SBA.

But the information sent to French prosecutors shows that much of the cash was then channeled to a Lebanese company controlled by Ghosn associates, the sources said.

The total sum paid by Renault is in the double-digit millions of dollars, one source said.

“We categorically deny the allegations of potential embezzlement in Oman,” said Ghosn’s French lawyer, Jean-Yves Le Borgnet.

Renault spokesman Frederic Texier declined to comment, while the French financial prosecutor’s office did not respond to requests for comment and SBA could not be reached.

Responding last month to earlier reports about the Nissan payments via SBA, a Ghosn family spokesman said: “The dealer incentive payments were directed by regional heads, not the CEO, and rewarded top performing dealers around the world.”

Ghosn is awaiting trial in Japan on charges that he failed to report around ¥9 billion in Nissan pay he had arranged to receive after retirement. He has also been indicted for transferring personal investment losses to Nissan and steering $14.7 million (¥1.6 billion) in company funds to Saudi businessman Khaled Juffali.

Renault initially sought to avoid being drawn into the investigation initiated by Nissan — which ousted Ghosn as chairman days after his arrest — and for weeks avoided sharing the Japanese partner’s findings with its own board.

But Ghosn was eventually forced out as Renault chairman and CEO in January, when Michelin veteran Jean-Dominique Senard was appointed chairman, and the alliance partners embarked on an independent audit of their joint finances the following month.

Born in Brazil to Lebanese parents, Ghosn, 65, returned to Lebanon as a child and retains a powerful network of friends and associates there. A Beirut house was among several properties around the world that were purchased by Nissan for his use, as the company’s investigation revealed early on.

The joint audit of the Renault-Nissan BV alliance management organization has tallied €1.2 million (¥150 million) in Lebanese donations and other spending of questionable benefit to the carmakers, among preliminary results presented to Renault directors this week, two sources familiar with the matter said.

The audit is examining the use of four corporate jets financed by the Dutch-registered subsidiary and payments of around €170,000 (¥21.2 million) annually to Carlos Abou Jaoude, Ghosn’s personal lawyer in Lebanon, over six years, the sources said. There is no suggestion of any wrongdoing by the lawyer.

In an earlier complaint filed with French prosecutors in February, Renault turned over evidence that the €50,000 (¥6.2 million) rental cost of Ghosn’s Chateau de Versailles wedding in 2016 had been improperly charged to the company.

But the alleged Oman connection may deepen Renault’s exposure to the scandal unearthed by Nissan, which has strained their 20-year-old alliance, and raises questions about governance at the French parent company.

Cash from Ghosn’s own “CEO office” budgets at Renault as well as Nissan moved through the regional sales divisions to SBA and on to a Lebanese intermediary, Good Faith Investments Holding, the three people briefed on the findings said.

From there it flowed on to privately held entities, including a British Virgin Islands-registered vehicle that paid for a $15 million (¥1.7 billion) yacht, they said.

Renault’s findings, delivered to prosecutors late last week, also include evidence suggesting that some of the funds were passed to a California-based company co-founded by Carlos Ghosn’s son, Anthony Ghosn, the sources said.

There was no suggestion of any wrongdoing by Anthony Ghosn or that he knew about the origin of the funds invested in his firm, Shogun Investments LLC. The Ghosn family spokesman, who also represents Anthony, declined to comment.

Carlos Ghosn has not been charged with any offenses in relation to the findings of either carmaker concerning incentive payments to SBA, the Omani partner, the spokesman added.
