What this changes in practice

An SA is a capital company whose organisation provides for specific rules relating to shares, governing bodies and decisions. It may meet certain financing and governance needs, but entails requirements that should be compared with those of other forms. The articles of association, powers of representation and control arrangements must be read together. The SA designation alone does not indicate a company’s financial standing or regulated status.
