Update on OMX’ 24 percent ownership in EDX London

EDX London Ltd, jointly owned by London Stock Exchange and OMX (76 and 24 percent respectively), offers trading and clearing in Scandinavian equity derivatives as well as over-the-counter equity derivatives services in London. During the period April-September 2005, EDX London traded a total of 10.1 million (9.2) contracts, mainly relating to Scandinavian equity derivatives. Although development of services for the over-the-counter equity derivatives market continued during the period, this service does not justify further investment. It is therefore today being announced in London Stock Exchange’s Interim Report for April-September that an exceptional impairment loss has been recognized in EDX London. The total impairment in EDX London amounts of GBP 22 m, principally in respect of the impairment of goodwill. OMX owns 24 percent of EDX London, which is treated in OMX’ accounts as an associated company. With reference to the contracts from the divestment of OM London Exchange’s business to EDX London in 2003, it is too early to estimate the total net income effect on OMX of EDX London in 2005.
