The ﬁrst type is one which generally desires to raise capital from the public. It includes all those companies whose shares are listed on the Singapore Exchange Limited (SGX), either on the main board or the secondary board known as Catalist. A company with more than 50 shareholders is a public company even if its shares are not listed on the SGX.
The other type of public company is the company limited by guarantee. Commonly used for the purpose of charity or to serve other national or public interests.
