Public listed companies are those that trade stocks or securities on an exchange (e.g. the ASX). Listed public companies are required to disclose information about their operations and performance, therefore a lot of information is available on the Australian Stock Exchange, the annual reports database and company websites.
Private or proprietary or unlisted companies are not always required by law to disclose information for public inspection, therefore they can be harder to research. Resources to research private companies include some databases, news sources and company websites. In Australia, large unlisted companies are required to lodge financial information for public inspection.
A Subsidiary company is one that is owned by another company. Financial information on a subsidiary is sometimes not available and it is necessary to read the reports of the parent company.
Non-profit organisations can fall into several categories including associations and not-for-profit unlisted public companies. For information on a non-profit organisation, look at the organisation's website and news sources.
