ISO15022 Corporate Actions Service

The London Stock Exchange launched a new SWIFT ISO15022 Corporate Actions product in August. The product delivers UK corporate actions in near real-time throughout the operational day over the SWIFT network, using the MT564 Corporate Actions Notification messages.


This product has been developed in-line with the UK Corporate Actions and SWIFT Data Vendor market practice guidelines. We are also delighted to announce we were the first Stock Exchange to supply centrally sourced corporate actions in near real-time over SWIFT. This development will help move the UK market closer towards the automation of corporate actions.

We have invested in the technologies to support ISO15022 messages utilising functionality our award winning SEDOL Masterfile™ database provides. However, assisting the industry in the effective processing of corporate actions is not something that just happens over night. This is demonstrated by the fact that the experience that we have in formulating and delivering corporate actions data has been the result of over 20 years of activity in this area.


For further information about our ISO15022 Corporate Actions Service please call our Information Sales helpline on +44 (0)20 7797 3009 (STX 33009) you can email us at infosales@londonstockexchange.com and we will contact you shortly.


SEDOL UK Corporate Action Download

Customers who take the SEDOL Masterfile Data Download product can also take UK Corporate Action (CA) data in a flat file format via the same FTP method. Change files are made available three times a day, starting at 12 noon, and then again at 6pm and midnight GMT. The data is linked to the SEDOL Masterfile thereby enabling SEDOL customers to not only track the changes to the data, but also take the reason for the change to any UK data as a result of a corporate action.
