Types of shares
These may be ordinary shares, which confer upon the shareholder the right to vote at a General Shareholders' Meeting and to receive dividends in accordance with the company's profit distribution policy. This is the most common type. Or they may be preferred shares, if they also confer some additional privilege that gives them priority over ordinary shareholders; mainly, a greater share in the distribution of profits or in the liquidation share. Sometimes this privilege involves the loss of other rights, such as voting rights.
They may be registered, depending on their issue, if they are linked to the holder's name as it appears in the company's shareholder registers. Typically companies in the banking and utilities sectors. They can also be bearer shares if they aren't associated with a name and so don't specify who owns them.
Those with voting rights have the right to attend the Company's General Meetings based on their voting rights. Most listed shares are eligible to vote. However, some shares do not give such a right in exchange for another economic benefit, such as a preference over the preferred dividend or a liquidation share. There may be companies that issue both types.
The authorised ones, according to their amount outstanding, are those issued in line with the company's Bylaws; those outstanding are those in the hands of investors; treasury shares are those repurchased by the company and which remain with it; while issued shares refers to those put into circulation, being the sum of those outstanding and treasury shares.
Lastly, gold shares grant a number of special rights that give the holder greater power over the company. This type is issued for example in privatisation processes.
