(6)The Commission has concluded that Australia, Indonesia and South Korea have in place supervisory and regulatory arrangements which comply with a series of operational standards reflecting the essential elements of the Union's supervisory and regulatory arrangements applicable to exchanges. Therefore, it is appropriate to consider the supervisory and regulatory arrangements applied to exchanges located in those third countries as at least equivalent to those applied in the Union for the purposes of Article 107(4) of Regulation (EU) No 575/2013.
