This document discusses the differences between private and public companies under business law. It notes that private companies are restricted in their ability to offer shares to the public, must have a minimum of 1 member and maximum of 50 members, have less stringent financial disclosure requirements, and more flexibility in share transfers and management compared to public companies. Public companies on the other hand can offer shares to the general public through a stock exchange listing, must have a minimum of 3 members, are subject to more regulatory requirements around financial disclosure, share transfers, and management structures. The key differences between the two center around ownership, capital raising activities, and transparency requirements.
