To which company are the machines and territories sold too, and who owns the majority stake of the "spin" out company?

I have heard that so often, that this or that technology is faded out in the car industry, and in reality, that just ment, the factory is carefully dissasembled, shipped to some 2nd world or 3rd world country, reassembled and buisness just continus or more often then not, actually expands. Fridges, diesel cars, you name it.
