Some statistics about distribution of shareholding:
Europe, without Germany 20.7%
Shareholders exceeding 5 % total 17.6%
Deutsche Bank AG 10.4%
Emirate of Kuwait 7.2%
Free Float 82.4%
Institutional Investors 54.4%
Private Investors (1.8 million) 28.0%
I don't think there are a lot of "high up executives" as shareholders,
though it is correct to state that only a minority of the shares are held in
the USA. I don't know who holds the 17.6% of shares not quoted.
It won't surprise you to know that the Kuwaiti government shareholding
sometimes gets controversial...
