"Ltd" stands for "Limited," which is a type of business structure. It indicates that the owners' liability is limited to the amount they invested in the company. This means that if the company faces financial difficulties, the personal assets of the owners are generally protected from creditors. In many countries, including the United Kingdom and Australia, a limited company can be either private or public. A private limited company, often denoted as Pty Ltd or simply Ltd, cannot sell shares to the public, while a public limited company, known as PLC, can. This structure helps attract investors while minimizing personal risk.
