Classification of Companies
There are 4 different types of businesses that can be registered:
- Companies limited by shares : Members are usually shareholders and their liability is limited to the nominal (nominal capital is defined as the capital with which the company was incorporated) value of their shares plus any unpaid amount on their shares.
- Companies limited by guarantee : The difference with these companies is that members can place a guarantee on the company which may only be enforced on the winding up of the company and is not an asset of the company which may be charged during its life. These companies have no share capital unlike companies limited by shares.
Often non-profit companies and charities use this method.
- Unlimited liability companies : The unlimited liability company was the original form of registered company under the 1844 UK Act. It is defined in Australia in the corporations act as a company whose members have no limit placed on their individual liability to contribute to the debts of the company.
- No liability companies : In Australia, companies may only be registered as no liability where:
- the company has share capital
- the company’s constitution states that its sole objects are mining purposes
- the company has no contractual right under its constitution to recover calls made on its shares from a shareholder who fails to pay them s112(2)
