Final answer:
Nestlé's two stock types were bearer and registered shares, with restrictions historically placed on foreigners regarding share ownership.
Step-by-step explanation:
The Nestlé Corporation, a prominent Swiss multinational corporation, historically issued two types of common stock: bearer shares and registered shares. In the case of Nestlé's stock structure, bearer shares were physical certificates that conferred ownership to whoever held the physical paper, while registered shares were recorded and tracked by the company, listing the owner's name and other pertinent details.
Regarding ownership by non-Swiss nationals, it used to be the case that foreigners were limited in what type of shares they could hold due to regulatory considerations, often restricted to registered shares.
