* The corporation investigated its own chairman (and CEO of its larger alliance), based on a whistleblower's report.
* A corporate chairman/CEO was arrested by the government, and the accusation is not massive fraud but under-reporting his own compensation and making personal use of corporate assets.
* A chair/CEO of a global corporation wanted $8.5 million in salary, and that was considered too much (this was a response from European stakeholders too). He took less.
Perhaps some people with experience in Japanese business can provide context for what we are seeing.
EDIT: Corrected Ghosn's title
EDIT2: Corrected the allegations by the government. I had been reading the NY Times article, not the one linked above.
