Stock typically takes the form of shares of common stock 
(or voting shares). As a unit of ownership, common stock 
typically carries voting rights that can be exercised in 
corporate decisions. Preferred stock differs from common 
stock in that it typically does not carry voting rights but 
is legally entitled to receive a certain level of dividend 
payments before any dividends can be issued to other 
shareholders.[1][2] Convertible preferred stock is 
preferred stock that includes an option for the holder to 
convert the preferred shares into a fixed number of common 
shares, usually anytime after a predetermined date. Shares 
of such stock are called "convertible preferred shares" 
(or "convertible preference shares" in the UK)

Although there is a great deal of commonality between the 
stocks of different companies, each new equity issue can 
have legal clauses attached to it that make it dynamically 
different from the more general cases. Some shares of 
common stock may be issued without the typical voting 
rights being included, for instance, or some shares may 
have special rights unique to them and issued only to 
certain parties. Note that not all equity shares are the 
same
