Some of the Silicon Valley dealings by Mr. Ghosn’s son, Anthony Ghosn, and the Oman connection have emerged previously in the criminal case. The younger Mr. Ghosn, who resides in the U.S., hasn’t been charged with wrongdoing.
People at both Nissan and Renault, as well as those close to Mr. Ghosn, said they see the Oman-related charge as the most serious one against him.
In March 2015, the Ghosns set up in Delaware an investment vehicle called Shogun Investments, which Mr. Ghosn described as a fund that would invest in Silicon Valley startups. Mr. Ghosn was majority owner while his son, Anthony, held a stake, according to people familiar with the matter. The younger Mr. Ghosn, who was about to graduate from Stanford University, was working at the time as chief of staff for Silicon Valley venture capitalist Joe Lonsdale, providing the elder Mr. Ghosn a close-up view of the tech investment world. The lofty returns had stunned him, according to one of the people.
