Nissan Motor Co. paid about $100,000 (about 11.3 million yen) a year to the older sister of Chairman Carlos Ghosn although she did nothing for the company, the automaker said Nov. 22.

The payments to the sister, based on a contract for advisory work, began in 2002, a year after Ghosn took on the concurrent roles of chief executive officer and president at Nissan, company officials said, citing the results of an in-house investigation.

Nissan sources said that in total, Ghosn’s older sister received close to $1.7 million from the Japanese automaker.

“Although we have paid the amounts, I have also been informed that there were no actual results of her work,” a Nissan executive said Nov. 22.

Nissan officials began their investigation into questionable use of funds by Ghosn after a whistle-blower tipped them off. In the course of the investigation, officials said they realized the company was paying Ghosn’s older sister for doing nothing.

Ghosn was arrested on Nov. 19 on suspicion of under-reporting his income in Nissan’s annual securities reports over a five-year period.

Later on the day of the arrest, Nissan President Hiroto Saikawa held a news conference and gave three broad areas of questionable acts by Ghosn: under-reporting his executive salary; using investment funds for personal expenditures; and suspect spending of company expenses.
