The concept of a corporation is distinct from a proprietorship or partnership business. Firstly, the owners or shareholders of the company run limited risk. When a corporation fails, a shareholder loses nothing beyond the face value of his shares. A partner or a proprietor, instead, is required to make good the business losses with personal funds. Secondly, in a corporation the ownership and the management are separate.

The shareholders are the owners who provide the capital but the management rests with the directors who are the agents of the shareholders. Shareholder risk should not be confused with business risk. Restricting the shareholder risk merely means passing on the excess risk to lenders, suppliers, managers, employees, government and society.
Thus, every participant – be it shareholder, lender, supplier – has stakes in the company. The principles of equity demand that a risk-taker should be rewarded. Hence, a corporation needs to be governed by practices that are ethical and rewarding to all its participants. Hence, sound corporate governance assumes relevance and validity.
