From the article:
Mr. Kaufmann, a German citizen who lives in Salzburg, Austria, is discreet about his finances. People close to him estimate he is worth hundreds of millions of euros and peg his investment in Leica at more than €60 million.
Makes me think of a movie a once saw:
"You're right, I did lose a million dollars last year. I expect to lose a million dollars this year. I expect to lose a million dollars *next* year. You know, Mr. Thatcher, at the rate of a million dollars a year, I'll have to close this place in... 60 years."
