Nissan Motor Co. Chairman Carlos Ghosn is suspected of having used multiple residences owned by the automaker without reporting that benefit as part of his income, sources familiar with the situation said Tuesday, as details begin to emerge regarding allegations against him over financial misconduct.

The new details — over his use, without charge, of properties in the Netherlands and three other countries — were revealed the day after a dramatic fall from grace by the 64-year-old, who has been a towering figure in the automotive industry.

Tokyo prosecutors believe the costs shouldered by Nissan should have been reported in securities reports as part of the remuneration he received from the company, according to the sources.
