Ikea trust is more of a shell game to keep the family in charge while avoiding tax and general scrutiny and liability.

In Denmark it is not too uncommon for the larger companies, JP/Politikens Hus which publishes two of the largest Danish newspapers is trust owned. Novo Nordisk and Mærsk which are the two largest danish companies are trust owned as well.

And Bosch.

Edit: Scratch that. Bosch is owned by a foundation.

The Ikea Trust is for the benefit of the family that controls it.
