A company is an entity that has a separate legal existence from its owners. The owners of the company are known as members or shareholders. Its legal status gives a company the same rights as a natural person which means that a company can incur debt, sue and be sued. Companies are managed by company officers who are called directors and company secretaries.
The most common type of company structure is a proprietary limited company (which has the words 'Pty Ltd' after the name). This type of company does not sell its shares to the public and has limited liability.
