The Euronext Single Order Book (SOB) will commence trading on Wednesday 14th January 2009. This initiative is working in parallel with the Euroclear Settlement of Euronext-zone Securities (ESES). The SOB will result in one single trading line for all listed securities, including those listed currently on more than one Euronext markets.
SOB introduces the concept of a Market of Reference (MoR) for each security within the Euronext markets of Amsterdam, Brussels & Paris. In the case of securities with a multiple listing within these markets, trading will take place on a single trading line, the designated MoR.
Additionally, the concept of CSD of Reference (CSDofR) is being introduced to indicate the place of settlement in relation to the ESES initiative.
The current SEDOL allocation rules permit a SEDOL to be allocated for place of listing or, in the absence of listing, place of trade. In order to reflect the single trading line, only the SEDOL code relating to the MoR will be retained. SEDOL codes that reflect other listings within the Euronext markets of Amsterdam, Brussels & Paris will be made inactive on the 14th January 2009.
Where the scenario exists that the country of the MoR differs from the country of the CSDoR, and a SEDOL already exists for each country, both SEDOL codes will be kept, one reflecting the MoR the other reflecting the CSDoR. As the current SEDOL allocation rules do not include place of settlement, this exception will remain until further consultation regarding SEDOL for country of settlement can be arranged.
SEDOL codes for the MoR for multiple listed securities, and those SEDOL codes which will be made inactive on the 14th January 2009 are available on the attached file SEDOL codes for SOB securities.xls. This data is based on a provisional list published by Euronext dated 27th November 2008. The final list will only be available at launch and the website will be updated accordingly.
If you require any further information, or would like to attend a working group for SEDOL related matters in Q1 and have not notified us already, please contact Emma Harding (0207 797 4156).
