(3)In order for a third country market to be considered equivalent to a regulated market within the meaning of Directive 2004/39/EC, the substantive outcome of the applicable legally binding requirements and supervisory and enforcement arrangements should be equivalent to Union requirements in respect of the regulatory objectives they achieve. The purpose of this equivalence assessment is therefore to verify that the legally binding requirements which apply to approved exchanges in Singapore are equivalent to the requirements laid down in Title III of Directive 2004/39/EC, and that those markets are subject to effective supervision and enforcement on an ongoing basis. Markets which are approved exchanges on the date of adoption of this Decision should be therefore identified as markets considered equivalent to a regulated market within the meaning of Directive 2004/39/EC.
