Singapore Exchange Limited (SGX) is an investment holding company located in Singapore and provides different services related to securities and derivatives trading and others. SGX is a member of the World Federation of Exchanges and the Asian and Oceanian Stock Exchanges Federation.
The companies listed on SGX belong to one of two groups: the companies listed on the SGX Mainboard and the companies listed on SGX SESDAQ. In order to be listed on the mainboard, a company has to fulfill some requirements set forth by SGX, while a listing on SESDAQ is not tied to the fulfillment of any additional conditions. SESDAQ was replaced on 26 November 2007 by the SGX Catalist after an extensive study of other market models and a public consultation in May 2007. (The word "Catalist" is an amalgamation of the words "Catalyst" and "List", to reflect the idea that the Catalist board could be used as a catalyst to propel growth upon listing. Catalist differs from SESDAQ primarily in its use of a sponsor system to determine a prospective company's suitability to list and as a corporate advisor to advise on listing and corporate governance issues.)
