apologies for this may be slightly off topic - in what ways can the management of a company discriminate between different classes of shareholders?
Regulations are designed to reduce discrimination between shareholders, eg a shareholder gets one vote for each share, and each shareholder gets access to the same information at the same time via published accounts and other public announcements. However, some management actions may favour certain types of shareholder. Large shareholders may be able to have private meetings with management. Some shareholders will prefer a high dividend policy rather than high capital growth due to their tax position. Shareholders have different appetites for risk, so management actions cannot please everyone. Best wishes Mark
