Public

A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are private enterprises in the private sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and therefore have associations and formal designations that are distinct and separate within the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kingdom, it is usually a public limited company (PLC). In France, it is a société anonyme (SA). In Germany, it is an Aktiengesellschaft (AG). While the general idea of a public company may be similar, the differences between types are meaningful and are at the core of international law disputes with regard to industry and trade.
