The Global Legal Entity Identifier Foundation (GLEIF) is an international non-profit organization established in June 2014 by the Financial Stability Board. Its mission is to ensure the operational integrity of the Global Legal Entity Identifier (LEI) System, which provides unique identification for legal entities involved in financial transactions. GLEIF is overseen by the LEI Regulatory Oversight Committee, ensuring transparency and integrity in the global financial market. GLEIF manages a network of partners to deliver reliable data for legal entity identification. It operates under a Master Agreement with LEI issuing organizations, detailing service standards. GLEIF publishes monthly performance reports and LEI data, offering insights into issuance metrics. While GLEIF does not issue LEIs directly, it plays a crucial role in maintaining the LEI system, which supports financial institutions and corporations in achieving regulatory compliance and enhancing market transparency.
