case, the doctrine of a veil of incorporation does not apply. Less common types of companies are: Most corporations by letters patent are corporations sole and not companies as the term is commonly understood today. Charter corporations these were the only types of companies before the passing of modern companies legislation. Now they are relatively rare, except for very old companies that still survive (of which there are still many, particularly many British banks), or modern societies that fulfill a quasi-regulatory function (for example, the Bank of England is a corporation formed by a modern charter). Statutory companies: Relatively rare today, certain companies have been formed by a private statute passed in the relevant jurisdiction. Note that "Ltd after the company's name signifies limited company, and PLC (public limited company) indicates that its shares are widely held."

In a company limited or unlimited by shares (formed or incorporated with a share capital), this will be the shareholders. In a company limited by guarantee, this will be the guarantors. Some offshore jurisdictions have created special forms of offshore company in a bid to attract business for their jurisdictions.

Private companies do not have publicly traded shares, and often contain restrictions on transfers of shares. In some jurisdictions, private companies have maximum numbers of shareholders.
