German tycoon Adolf Merckle commits suicide

The passionate skiier and mountain climber assembled a business conglomerate with about 100,000 employees and 30 billion euros ($40.45 billion) in annual sales.

His family controls a number of German companies including cement maker HeidelbergCement and generic drug company Ratiopharm.

But the empire was rocked last year by wrong-way bets made on shares in Volkswagen after a surprise stakeholding announcement from Porsche sent the VW share price rocketing as short sellers scrambled to cover their positions.

Banking sources had told Reuters the family lost hundreds of millions of euros on investments, with about 400 million euros lost on Volkswagen shares alone.

Since then the family has been in talks for weeks with banks to renegotiate loans. Banking sources said on Tuesday his death was not expected to affect loan agreements with the family.

Shares in HeidelbergCement fell as much as 12.5 percent following the news of Merckle's death and ended the day down 6.2 percent at 31.25 euros.

"Some investors are afraid that there will be no one to lead negotiations during this sensitive situation for the company," one trader in Frankfurt said.

Psychologists and other mental health experts have said suicide rates could creep up as a result of the financial crisis.

Last month Frenchman Thierry Magon de la Villehuchet, 65, a co-founder of money manager Access International, was found dead in a New York office building, reportedly distraught over losing up to $1.4 billion in client money to Bernard Madoff's alleged fraud. He slit his wrists with box cutters.
