Management is responsible for the preparation and presentation of the condensed interim financial separate statements in accordance with the requirements of International Accounting Standards 34 Interim Financial Reporting, announced in the form of European Commission regulations.

Our responsibility is to form a conclusion on the condensed interim separate financial statements based on our review.

Scope of Review

We performed the review in accordance with National Standard on Review Engagements 2410 in the wording of International Standard on Review Engagements 2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity", adopted in a resolution passed by the National Council of Certified Auditors.

A review of financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, applying analytical and other review procedures.

A review is substantially less in scope than an audit conducted in accordance with National Standards on Auditing in the wording of International Standards on Auditing. In consequence, a review is not sufficient to obtain assurance that all significant matters that might be identified in an audit, have been identified. Accordingly, we do not express an audit opinion on the accompanying condensed interim separate financial statements.
