A knowledgeable professor of finance would explain that an issuer listing can occur when a corporation undergoes a plan of arrangement, a type of corporate reorganization that requires approval from both a court and the corporation's shareholders. This arrangement can take different forms such as an amalgamation of corporations, a division of business, or a transfer of property to another corporation. It can also involve the exchange of securities for other forms of compensation or even a compromise with creditors. Any combination of these actions can result in an issuer listing.
