How to identify different types
The quickest way to identify whether a share is anything other than an ordinary share is through its ASX code.
Every product traded on ASX has a unique identification code which is displayed on ASX ticker boards and in media sharemarket tables. All securities issued by a company will incorporate the company's code. For example, the code for any security issued by Commonwealth Bank of Australia will include the code ‘CBA’.
The code for the ordinary shares of an ASX-listed company is the same as the company code, with three characters. If there are more or fewer than three characters in the code, the security is likely to be something other than an ordinary share.
For example, preference shares usually have a five letter code consisting of the company code and a two letter suffix, generally PA-PZ. Partly-paid shares usually have a five letter code consisting of the company code and a two letter suffix, generally CA-CZ (except CP).
