The Global Legal Entity Identifier System (GLEIS) is being established by the ROC to provide a greater view of systemic risk and improve analytics of global positions and transactions. The GLEIS requires financial entities to register for a LEI with a Local Operating Unit (LOU) creating a unique and unambiguous way to identify legal entities.

London Stock Exchange was sponsored by the FCA to be a Pre-LOU in June 2013, and commenced allocation of International Entity Identifiers (IEI) from August 2013. Following demonstration of its ability to meet the Principles and Recommendations set out by the ROC IEIs are now globally accepted for cross border regulatory reporting purposes under both Dodd Frank and EMIR. Firms that would like their Pre-LEI to be managed by the London Stock Exchange can now arrange to port their code over.

Mark Husler, Head of Product Management, Information Services, London Stock Exchange Group, stated:
"The LEI is an important initiative to help create transparency in the market place. The ROCs endorsement of London Stock Exchange means that firms can now use International Entity Identifier to satisfy all of their global regulatory reporting requirements, such as EMIR, Dodd-frank and others. Through our UnaVista platform the industry can request their own Pre-LEI for each of their entities and access a consolidated file of all Pre-LEIs through our UnaVista platform."
