In a limited company, the liability of members or subscribers of the company is limited to what they have invested or guaranteed to the company. Limited companies may be limited by shares or by guarantee. The former may be further divided in public companies and private companies. Who may become a member of a private limited company is restricted by law and by the company's rules. In contrast, anyone may buy shares in a public limited company.
Limited companies can be found in most countries, although the detailed rules governing them vary widely.
