A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as:
A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duty according to the publicly declared incorporation, or published policy. When a company closes, it may need to be liquidated to avoid further legal obligations.
Companies may associate and collectively register themselves as new companies; the resulting entities are often known as corporate groups.

Meanings and definitions

One can define a company as an "artificial person", invisible, intangible, created by or under law, with a discrete legal personality, perpetual succession, and a common seal. Except for some senior positions, companies remain unaffected by the death, insanity, or insolvency of an individual member.


The English word company has its origins in the Old French term compagnie, meaning a "society, friendship, intimacy; body of soldiers", which came from the Late Latin word companio, first attested in the Lex Salica as a calque of the Germanic expression gahlaibo, related to Old High German galeipo and to Gothic gahlaiba.

Semantics and usage

By 1303, the word referred to trade guilds. Usage of the term company to mean "business association" was first recorded in 1553,
and the abbreviation "co." dates from 1769.

Less common types of companies are:
When "Ltd" is placed after the company's name, it signifies a limited company, and "PLC" indicates that its shares are widely held.
In the legal context, the owners of a company are normally referred to as the "members". In a company limited or unlimited by shares, this will be the shareholders. In a company limited by guarantee, this will be the guarantors. Some offshore jurisdictions have created special forms of offshore company in a bid to attract business for their jurisdictions. Examples include "segregated portfolio companies" and restricted purpose companies.
There are, however, many, many sub-categories of types of company that can be formed in various jurisdictions in the world.
Companies are also sometimes distinguished for legal and regulatory purposes between public companies and private companies. Public companies are companies whose shares can be publicly traded, often on a stock exchange which imposes listing requirements/Listing Rules as to the issued shares, the trading of shares and future issue of shares to help bolster the reputation of the exchange or particular market of an exchange. Private companies do not have publicly traded shares, and often contain restrictions on transfers of shares. In some jurisdictions, private companies have maximum numbers of shareholders.
A parent company is a company that owns enough voting stock in another firm to control management and operations by influencing or electing its board of directors; the second company being deemed as a subsidiary of the parent company. The definition of a parent company differs by jurisdiction, with the definition normally being defined by way of laws dealing with companies in that jurisdiction.
