(27)The ultimate objective of cooperation on audit oversight with Brazil, Dubai International Financial Centre, Guernsey, Indonesia, the Isle of Man, Jersey, Malaysia, South Africa, South Korea, Taiwan and Thailand is to reach mutual reliance on each other's oversight systems. In that way, transfers of audit working papers or other documents held by statutory auditors or audit firms and of inspection or investigation reports should become the exception. Mutual reliance would be based on the equivalence of auditor oversight systems of the Union and of the third country or territory concerned.
