A PLC, or Public Limited Company, is a type of business structure in which shares can be bought and sold by the public on a stock exchange. This allows the company to raise capital from a wide range of investors. PLCs are required to meet specific regulatory standards and disclose financial information to ensure transparency for shareholders. In a PLC, shareholders have limited liability, meaning they are only responsible for the company's debts up to the amount they invested. This structure is common in many countries and is often used by larger companies seeking to expand their operations and market presence.
