This document discusses different ways to classify companies based on their incorporation, liability, number of members, control, and ownership. It outlines that companies can be chartered, statutory, or registered based on how they are incorporated. Based on liability, companies are either limited or unlimited. Private companies have fewer than 50 members, while public companies must have a minimum paid-up capital and are not restricted in the number of members. Holding companies control other subsidiary companies. Government companies have majority ownership by the central or state government, while foreign companies are incorporated outside of India.
