The Organization of Supreme Audit Institutions of MERCOSUL Countries and Associated (EFSUL), currently composed by SAIs of Argentina, Bolivia, Brazil, Chile, Ecuador, Paraguay, Uruguay and Venezuela, emerged because of the common interest in monitor the resulting acts of the integration of countries by the Treaty of Asunción, signed in 1991, as well as to share information and experiences of the institutions.
