Suicide note mentions insurer's ex-chairman

The former chairman of Zurich Insurance was mentioned in a note the company's finance chief left before his death earlier this week.

"The board sees it as its prime responsibility to look into the question as to whether there was undue pressure placed on our CFO," he said.

Wauthier, who was 53 and married with two children, had been CFO at the global insurer since October 2011. He was found dead at his home in Switzerland on Monday.

Wauthier's death is the second to rock Switzerland's corporate world in as many months. Carsten Schloter, CEO of SwisscomSCMWY, was found dead in late July in a case police also assumed was suicide.
