Country Code Reclassification
30/10/2007
Channel Islands Stock Exchange Country Reclassification
Further to the introduction of a separate country code for the Channel Islands, the country classification of the Channel Islands Stock Exchange is now Guernsey (GG), where previously it was Great Britain (GB).
Historically, securities trading on UK platforms and the Channel Islands Stock Exchange shared the same SEDOL code. However, due to the revised country classifications, UK and Channel Islands are no longer considered to be the same country, and as such will receive separate SEDOL codes.
Attached is a list of all existing securities on SEDOL Masterfile affected by these changes. A new SEDOL will be allocated for the Channel Islands Stock Exchange listing for these securities, and the existing SEDOLs will remain as the GB code.
These changes will be implemented on Friday, 7 December 2007.
Should you have any questions, please contact Jo Rule (0207 797 1103) or Emma Harding (0207 797 4156).

Jersey, Guernsey & Isle of Man - ISIN allocation
Recent changes to ISO 3166 Country Codes elevating the crown dependencies of Jersey, Guernsey and the Isle of Man to the main country code list will have an impact on the allocation of GB ISIN codes.
Currently securities falling under these areas would have an ISIN allocated that begins with GB, however, from the 4th September 2006 new securities that fall under the new country codes, according to ISIN rules, will be allocated an ISIN beginning with either JE for Jersey, GG for Guernsey or IM for Isle of Man.
Existing securities with GB ISINs for Jersey, Guernsey or Isle of Man will remain unchanged.
