SEDOL Allocation for Multiple Trading Currencies 02/11/09

07/09/2009

On Tuesday 12 May the London Stock Exchange hosted the first SEDOL Masterfile Technical Workshop. Following this we have continued our consultation visiting several organisations to gain a greater understanding of the use of SEDOL through all areas of the business in relation to the trade lifecycle.

Throughout the consultation process the separate elements of the Market level SEDOL consultation paper received mixed feedback. At this point we have decided not to proceed with Market level SEDOL allocation due to market impact. Additionally, we feel it is unnecessary to move forward with separate SEDOL allocation for MTFs.

The remaining element of the consultation paper, allocation of separate SEDOL codes for multiple trading currencies on a single platform, received the majority of positive feedback. This proposal has been identified as meeting a business need, as well as streamlining the SEDOL allocation rules.

Under the current allocation rules, separate SEDOL codes for multiple trading currencies on a single platform are limited to Exchange Traded Funds (ETFs) trading on the London Stock Exchange (the Exchange). The existing process uses SEDOL to distinguish the different trading currency while the ISIN remains the same on each, example below:

SEDOL           DESCRIPTION                                                      ISIN                                      OPOL

B59M1R5       CAC'40' 2X SHORT FD SHS EUR(EUR)          IE00B4QNHF45                   XAMS

B4QNHF4      CAC'40' 2X SHORT FD SHS EUR(EUR)          IE00B4QNHF45                   XLON

B54TDX1       CAC'40' 2X SHORT FD SHS EUR(GBP)          IE00B4QNHF45                   XLON

As there is already a precedence for SEDOL codes allocated against multiple currencies for the Exchange's ETFs, implementation of this rule across affected markets will have minimal impact on users. An effective date for implementation has been scheduled for 2nd November 2009. A list will be published closer to the date detailing the affected instruments.
