Aktiengesellschaft

Aktiengesellschaft (German pronunciation: [ˈʔakt͡si̯ənɡəˌzɛlʃaft]; abbreviated AG pronounced [ʔaːˈgeː]) is a German word for a corporation limited by share ownership (i.e. is owned by its shareholders) and may be traded on a . The term is used in Germany, Austria, Switzerland, South Tyrol and for companies incorporated in the German-speaking region of Belgium. It is also used in Luxembourg (French pronunciation: ​[aktjɛ̃ʒøzɛlʃaf]), though the French-language equivalent, Société Anonyme, is more common.

The German word Aktiengesellschaft is a compound noun made up of two elements: Aktien meaning shares, and Gesellschaft in this context meaning corporation. An approximate English transliteration can therefore be dictated as "share corporation". In German the use of the term Aktie for share is restricted to Aktiengesellschaften. Shares in other types of German companies are called Anteile rather than Aktien.

In Germany and Austria, the legal basis of the AG is the German Aktiengesetz (abbr. AktG) or the Austrian Aktiengesetz (abbr. AktG). The German commercial law (§ 19 Handelsgesetzbuch) requires all corporations to specify their legal form in their name which tells the public their limitation of liability, all German (required by § 4 Aktiengesetz) and Austrian stock corporations include Aktiengesellschaft or AG as part of their name, frequently as a suffix.
