Deutsche Börse AG celebrated its 25 anniversary on the trading floor of the Frankfurt Stock Exchange on Monday. Numerous clients, regulators, former executive board and supervisory board members as well as employees joined the bell-ringing ceremony to honour this anniversary. On 11 December 1992, the former owners of the three independent companies – Frankfurter Wertpapierbörse AG, DTB Deutsche Terminbörse GmbH and Deutsche Kassenverein AG – opted to merge their businesses. The merger became effective on 1 January 1993, marking the foundation of Deutsche Börse AG. This created an integrated market infrastructure provider in Frankfurt and in Germany for the first time.
