(2)In the case of a company incorporated in the United States whose transferable securities are admitted to trading on a regulated market of a Member State, but which are not admitted to trading in the United States, Member States should ensure that all the audit engagements related to the financial statements of such companies are subject to their systems of public oversight, quality assurance, investigation and penalties. Where such companies are listed in more than one Member State, the Member States concerned should cooperate to ensure that the audit engagement is included in the scope of one of their systems of public oversight, quality assurance, investigation and penalties. Those arrangements should not prevent Member States from establishing cooperative arrangements on quality assurance reviews between their competent authorities and the competent authorities of the United States.
