There are three main kinds of shares that can be issued by companies: 1. Equity shares represent ownership in the company and have voting rights but no fixed dividend. Dividends are paid after preference shares. 2. Preference shares have a fixed dividend rate and priority over equity shares in dividend payments and capital repayment if the company is liquidated. They typically lack voting rights. 3. Deferred shares are the most junior shares with dividends and capital repayment only occurring after all other shares. Public companies cannot issue deferred shares.
