Having developed a comprehensive set of requirements for the legal entity identifier (LEI) system, The Clearing House Association, along with 12 other trade associations, are now looking to identify one or more solution providers who, individually or collectively, can build the LEI system capable of meeting or exceeding the expectations outlined in the May 3 requirements document. To facilitate the identification process, the trade associations are conducting a solicitation of interest exercise and are inviting solution providers who meet the prerequisites to respond to the questions in the document by June 3, 2011.
