Quality control and ethical
				 
				requirements
				
					We apply the provisions of the regulation of the National Council of Statutory Auditors with regard 
					to internal quality control in the wording of International Standard on Quality Control 1 and accordingly 
					maintain a comprehensive system of quality control including documented policies and procedures 
					regarding compliance with ethical requirements, professional standards and applicable legal and 
					regulatory requirements.
				
				
					We comply with the independence and other ethical requirements of the International Code of Ethics 
					for Professional Accountants (including International Independence Standards) issued by the 
					International Ethics Standards Board for Accountants
					 
					as adopted by resolution of the National Council 
					of Statutory Auditors, which is founded on fundamental principles of integrity, objectivity, professional 
					competence and due care, confidentiality and professional behaviour.
				
				
					Summary of the work performed
				
				
					Our
					 
					planned
					 
					and
					 
					performed
					 
					procedures
					 
					were
					 
					aimed
					 
					at
					 
					obtaining
					 
					reasonable
					 
					assurance
					 
					whether 
					the
					 
					consolidated
					 
					financial
					 
					statements
					 
					in
					 
					the
					 
					ESEF
					 
					format
					 
					were
					 
					marked-up,
					 
					in
					 
					all
					 
					material
					 
					respects, 
					in compliance with the applicable requirements. Our procedures included in particular:
				
				
					•
					obtaining an understanding of the process of preparation  of the consolidated financial statements 
					in the ESEF format, including the process of selection and application  by the Group of the XBRL 
					tags and ensuring the compliance with the ESEF Regulation, including  understanding 
					the mechanism of the internal control system related to this process;
				
				
					•
					reconciliation, on a selected sample,  of the marked-up information contained in the consolidated 
					financial statements in the ESEF format to the audited consolidated financial statements;
				
				
					•
					evaluating of compliance with the technical standards regarding the specification of a single 
					electronic reporting format, including the use of XHTML;
				
				
					•
					evaluating the completeness of marking up the consolidated financial statements in the ESEF 
					format using the iXBRL tags;
				
				
					•
					evaluating the appropriateness of the
					 
					use of XBRL tags selected from the taxonomy defined 
					in the ESEF Regulation and whether the extension markups were used appropriately where 
					no suitable element in taxonomy defined in the ESEF Regulation has been identified; 
				
				
					•
					evaluating the appropriateness of anchoring of the extension elements to the ESEF taxonomy 
					from the ESEF regulation;
				
				
					We believe that the evidence we have obtained is sufficient and appropriate to provide a basis 
					for our conclusion.
				
				
					Conclusion
				
				
					In our opinion, based on the procedures performed, the consolidated financial statements in the ESEF 
					format were marked-up, in all material respects, in compliance with the requirements of the ESEF 
					Regulation.
