The main features of public limited companies include:

1. Limited Liability: Shareholders' liability is limited to the amount they have invested in the company. Their personal assets are not at risk for the company's debts or obligations.
2. Capital and Shareholders: PLCs have a large number of shareholders, and they raise capital by issuing shares to the public. This capital can be used for expansion, investment, or other business activities.
3. Publicly Traded: PLCs list their shares on one or more stock exchanges, allowing the shares to be bought and sold by the general public. This provides liquidity to the shareholders as they can sell their shares at any time on the open market.
4. Regulatory Requirements: PLCs are subject to more stringent regulatory requirements than private companies, including financial reporting, disclosure, and corporate governance standards. These regulations aim to protect the interests of shareholders and the public.
5. Corporate Governance: PLCs typically have a board of directors responsible for making strategic decisions and overseeing the company's management. There are also statutory requirements for holding general meetings where shareholders can vote on important matters.
