Market Level SEDOL Allocation
In February 2008 the London Stock Exchange published the Market Level SEDOL Allocation paper proposing the allocation of Market Level SEDOL codes to complement the existing Country Level SEDOL codes. In addition, we proposed changing our allocation rules for multi-lateral trading facilities (MTFs) and multiple currencies listed on the same market.
The results of our proposal are published in the Market Level SEDOL Allocation Response and Next Steps paper. In summary, despite strong support for the theory of the proposal, the implementation of the additional level of identifier granularity would require more time to analyse the impact on legacy systems and internal processes. Therefore, we will not proceed with our proposal to begin allocation in September this year.
However, among the respondents who were enthusiastic there is a desire to keep market level SEDOL codes on the agenda. In addition, feedback indicated a requirement for more two-way dialogue between our reference data team and customers, and more clarity on both our existing policies and future strategies. To this end, we propose hosting a regular Reference Data workshop for all interested parties to discuss the issues raised through this consultation, and other potential future developments. If you would like to part in this initiative, please contact us with your contact details and any additional topics you would like included in the agenda.
