Sedol Allocation

Revised SEDOL Allocation Guidelines – implementation 4^th July 2011

In order to improve timeliness and availability of SEDOL codes, and to provide a more transparent SEDOL allocation service to our customers, the SEDOL Allocation Guidelines have been revised.

Currently, in respect of corporate actions (with the exception of several country specific scenarios) ISIN codes are replaced on existing SEDOL codes on the corporate action effective date. However, from Monday 4^th July 2011, new SEDOL codes will be allocated for all newly allocated ISIN codes.

Introducing this change will remove the current exceptions attached to SEDOL code allocation and will enable SEDOL codes to be issued in advance of the corporate action effective date.

Any ISIN changes that have not been reflected within the SEDOL Masterfile prior to  4^th July will be eligible to have new SEDOL codes issued, regardless of the corporate action date. No retrospective changes will be made to the system for existing SEDOL codes that are showing the correct ISINs.

Please find attached a revised version of the SEDOL Allocation Guidelines for your reference. (file pdf - 18 KB)

Further to the implementation of the SEDOL allocation rules on 25th June 2007, we will be creating an exception for Spanish incorporated entities regarding subdivisions and consolidations.

Where a subdivision or consolidation occurs to a Spanish incorporated entity, and a new ISIN is released, we will be allocating a new SEDOL code. This exception will be effective immediately. Requests for new codes falling under this exception must be directed to smfnewissues@londonstockexchange.com and must not be created by external parties.

This exception is necessary due to a technical issue for Spanish domestic custody & settlement. We do not anticipate any further exceptions to the SEDOL allocation rules.

For specific details please refer to the attached spreadsheet ‘SEDOL Allocation Rules’.
