I hope this is of some use.
According to last week's flight international, Airbus ownership is as follows:-
Through ownership of EADS:-
French Government 12%
Spanish Government 5%
Lagardere publishing 12%
Hamburg (city of?) 1.5%
Publicly Traded 24%
That totals the 80% owned by EADS
BAE SYSTEMS owns the other 20%
Interestingly the German government and UK government have no ownership.
I hope this serves as a reference in future discussions, and avoids any misunderstandings as to "Who owns Airbus".
