The latter can then remit part of its profits by paying dividends to its shareholders.The shares of a company must be bought and sold on the stock exchange for a public company or on a private market for a private company. In the event that an enterprise is forced to close its doors, the sum obtained, following the sale of its assets, will be used to pay its debts, taxes and preferred shareholders in the first place, then the balance will be paid to the common shareholders in the order of liquidation.
