These standards require that we plan and perform procedures to obtain reasonable assurance
whether the consolidated financial statements in the ESEF format were marked up, in all material
respects, in compliance with the specified criteria.
Reasonable assurance is a high level of assurance, but it does not guarantee that the engagement
performed in accordance with KSUA 3001PL and, where relevant, in accordance with KSUA 3000 (R)
will always detect the material misstatement (significant non-compliance with the requirements).
The selection of the procedures depends on the auditor's judgement, including the auditor's
assessment of the risk of material misstatements, whether due to fraud or error. In performing the
assessments of this risk, the auditor shall consider the internal control related to the preparation of the
consolidated financial statements in the ESEF format in order to plan appropriate procedures to
provide the auditor with sufficient evidence appropriate to the circumstances. The assessment of the
functioning of the internal control system was not carried out in order to express an opinion on the
effectiveness of its operation.
Quality management and ethical
requirements
We apply the National Standard on Quality Control 1 in the wording of the International Standard on
Quality Management (PL) 1 – “Quality Management for Firms that Perform Audits or Reviews of
Financial Statements, or Other Assurance or Related Services Engagements” as issued by the
International Auditing and Assurance Standards Board and adopted by the resolution of the Council of
the
Polish Agency for Audit Oversight
(“NSQC 1”). In accordance with the requirements of NSQC 1,
we operate a system of quality management including documented policies or procedures regarding
compliance with ethical requirements, professional standards and applicable legal and regulatory
requirements.
When performing the engagement, we have complied with the independence and other ethical
requirements in the Code of ethics. The Code of ethics is founded on fundamental principles of
integrity, objectivity, professional competence and due care, confidentiality and professional
behaviour. We also complied with other independence and ethical requirements that apply to this
assurance engagement in Poland.
