Article 28 4.

The audit report shall be signed and dated by the statutory auditor. Where an audit firm carries out the statutory audit, the audit report shall bear the signature of at least the statutory auditor(s) carrying out the statutory audit on behalf of the audit firm. Where more than one statutory auditor or audit firm have been simultaneously engaged, the audit report shall be signed by all statutory auditors or at least by the statutory auditors carrying out the statutory audit on behalf of every audit firm. In exceptional circumstances Member States may provide that such signature(s) need not be disclosed to the public if such disclosure could lead to an imminent and significant threat to the personal security of any person.
