(12)It is important to ensure high-quality statutory audits within the Union. All statutory audits should therefore be carried out on the basis of the international auditing standards adopted by the Commission. As international auditing standards are designed to be usable for entities of all sizes, of all types and in all jurisdictions, the competent authorities in Member States should take into account the scale and complexity of the business of small undertakings when assessing the scope of application of international auditing standards. Any provision or measure adopted by a Member State in this regard should not result in statutory auditors or audit firms being unable to carry out statutory audits in compliance with the international auditing standards. Member States should be allowed to impose additional national audit procedures or requirements only if they stem from specific national legal requirements relating to the scope of the statutory audit of annual or consolidated financial statements, meaning that those requirements have not been covered by the adopted international auditing standards, or if they add to the credibility and quality of annual financial statements and consolidated financial statements. The Commission should continue to be involved in the monitoring of the content of the international auditing standards and the process for their adoption by the International Federation of Accountants (IFAC).
