(4)Following such assessments, it appears that Australia, Canada, China, Croatia, Japan, Singapore, South Africa, South Korea and Switzerland have public oversight, quality assurance, investigation and penalty systems for auditors and audit entities that operate under similar rules to those set out in Articles 29, 30 and 32 of Directive 2006/43/EC. Therefore, it is appropriate to consider the public oversight, quality assurance, investigation and penalty systems for auditors and audit entities of those third countries as equivalent to the public oversight, quality assurance, investigation and penalty systems for auditors and audit firms of the Member States.
