Independence andethics

We are independent of the Company in accordance with the International Federation of Accountants' Code of Ethics for Professional Accountants ("the IFAC Code") as adopted by resolutions of the National Council of Statutory

Auditors and other ethical requirements that are relevant to our audit of the financial statements

Our audit approach

in Poland. We have fulfilled our other ethical responsibilities in accordance with these requirements and the IFAC's Code. During the audit, the key registered auditor and the registered audit firm remained independent of the Company in accordance with the independence requirements set out in the Act on Registered Auditors and in the EU Regulation.

As part of designing our audit, we determined materiality and assessed the risks of material misstatement in the financial statements. In particular, we considered where the Company's Management Board made subjective judgements; for example, in respect of significant accounting estimates that involved making assumptions and considering future events that are inherently uncertain. We also addressed the risk of management override ofinternal controls, including among other matters, consideration of whether there was evidence of bias that represented a risk of material misstatement due to fraud.

Materiality

The scope of our audit was influenced by the adopted materiality level. Our audit was designed to obtain reasonable assurance that the financial statements as a whole are free from material misstatement. Misstatements may arise due to fraud or error.

They are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including the overall materiality for

the financial statements as a whole. These thresholds,together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually and in aggregate on the financial statements as a whole.

The concept of materiality is used by the registered auditor both in planning and conducting an audit, as well as in assessing the effect of the misstatements identified during the audit and the unadjusted misstatements (if any), on the financial statements, and also when forming the registered auditor's report. Therefore, all opinions, assertions and statements contained in the registered auditor's report have been made taking into consideration the quantitative and qualitative materiality levels determined in accordance with the audit standards and the registered auditor's professional judgement.

Overall materiality	PLN 23.650 thousand (PLN 21.930 thousand in 2016)
Basis for determination	1% of the Company's total revenues
Rationale for the materiality benchmark applied	We have adopted total revenues as the basis for determining materiality because, in our opinion, it is an indicator commonly used by the users of financial statements to evaluate the Company's operations and is a generally adopted benchmark, especially for entities with significant level of external debt. We adopted the materiality threshold at 1% because based on our professional judgement it is within the quantitative materiality thresholds acceptable by the auditing standards.

We agreed with the Company's Audit Committee that we would report to them of misstatements identified during our audit of the financial statements above PLN 2.365 thousand, as well as any misstatements below that amount, that in our view, warranted reporting for qualitative reasons.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period. They include the most significant identified risks of material misstatements, including the identified risks of material misstatement resulting from fraud.

These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon. We summarized our response to these risks and, when deemed appropriate, presented the most important observations relating to these risks. We do not provide a separate opinion on these matters.

Key audit matter How our audit addressed the key audit matter

Recoverability of a deferred income tax asset and the existence of an inherent uncertainty over income tax settlements

As at the balance sheet date, the Company recognized a deferred tax asset of PLN 57 million, including PLN 48 million in respect of tax losses carried forward. The above amounts are material to the financial statements. The deferred income tax asset is described in Note 4.3 to the financial statements.

As at the balance sheet date, the Company was undergoing control proceedings. The subject of the proceeding is to assess the fairness of the declared tax bases as well as the correctness of the calculation and payment of the corporate income tax for 2013. The status of the inspection is described in Note 9.2 to the financial statements.

We paid special attention to the analysis of the correctness of the recognition of the deferred income tax asset due to the fact that it involves the need for material assumptions and judgements to be made by the Management Board. These relate to, in particular, the determination of the tax bases of the individual assets and liabilities, the assessment of the period and manner of their settlement, the probability that future taxable profits will arise, from which it will be possible to deduct tax benefits, among other things, in the face of the control proceedings in progress. As disclosed in Note 4.3, in assessing the recoverability of the deferred tax asset and the inherent uncertainty over income tax,the Management Board took into account the General Anti-Abuse Regulation. Changes in the assumptions made by the Management Board may lead to the recognition of deferred tax asset balances which differ significantly.

Bearing in mind the inherent risk of uncertainty over the material estimates made by the Management Board, we have concluded that this is a key matter for our audit.

Our audit procedures covered, in particular:

• gaining an understanding of and assessing the process of identification oftemporary differences and the calculation of deferred income tax assets;
• engaging PwC tax experts in analysing tax rulings and correspondence with the tax authorities and in assessing the tax implications of the material transactions to which the Company was a party and their effect on the recognition of deferred income tax assets and provisions for tax risks;
• discussing with the Management Board making a critical assessment of: (a)the assumptions and the estimates made by the Management Board with respect to the recoverability ofthe recognized deferred income tax assets, including the tax losses for the previous years; and (b)the Management Board's comprehensive analysis of the tax position of the Company with respect to the identification and assessment oftransactions and operations which might potentially be subject to the GAAR provisions, and their effect on deferred tax, the tax bases of assets and the provision for tax risk;
• reviewing the disclosures presented in the financial statements with respect to significant estimates and judgements relating to the recognized deferred tax asset and tax risks arising from the provisions of the General Anti-Abuse Regulation.

As a result of the procedures performed, based on the collected audit documentation, we did not find it necessary to make any material adjustments concerning the recognition and disclosures with respect to the income tax asset in the financial statement.

Fair value measurement of derivative instruments

The Company is a party to transactions in derivative instruments based on the volatility of interest rates, exchange rates. The derivative instruments are described in Note 8.2 to the financial statements.

In accordance with the Company's accounting policies, derivative instruments are measured at fair value at each balance sheet date. Determining the fair value of derivative instruments is an area which requires a material estimate of the Management Board because, due to there being no active market, it requires making assumptions about movements in interest rates, exchange rates in the future, and it involves using an instrument valuation model which is appropriate in a givensituation.

Bearing in mind the inherent risk of uncertainty over the material estimates made by the Management Board, we have concluded that this is a key matter for our audit.

Our audit procedures covered, in particular:

• gaining an understanding of and assessing the process of measuring derivative instruments, including the adopted methodology and the sources of market data and unobservable parameters;
• verifying the key parameters ofthe derivative instruments in comparison to external data, independent of the Company;
• using PwC in-house valuation specialists to perform independent fair value measurements of the derivative instruments;
• comparing the fair values calculated by the Management Board to the fair values calculated by us;
• assessing the differences in the fair value measurements of the derivative instruments between our valuations and the valuations prepared by the Management Board. In certain cases, we achieved results which differed from those calculated by the Company's management. However, in our opinion these differences are within an acceptable range in the light of taking into account the estimates relating to future interest rates, exchange rates in the valuation.

Based on the procedures performed, we concluded that the valuations fall within the expected range, and the disclosures in the financial statements as being in compliance with the requirements ofthe standards.

Responsibility of the Management and Supervisory Board for the financial statements

The Management Board of the Company is responsible for the preparation, based on the properly maintained books of account of annual financial statements that give a true and fair view of the Company's financial position and results of operations, in accordance with the International Financial Reporting Standards as adopted by the European Union,the adopted accounting policies, the applicable laws and the Company's Articles of Association, and for such internal control as the Management Board determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the

Company's Management Board is responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Management Board either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

The Company's Management Board and members of its Supervisory Board are obliged to ensure that the financial statements comply with the requirements specified in the Accounting Act. Members of the Supervisory Board are responsible for overseeing the financial reporting process.

Auditor's responsibility for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Auditing Standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in aggregate, they could reasonably be expected to influence economic decisions of users taken on the basis of these financial statements.

The scope of the audit does not cover an assurance on the Company's future profitability or the efficiency and effectiveness of the Company's Management Board conducting its affairs, now or in future.

As part of an audit in accordance with the Auditing Standards, we exercise professional judgement and maintain professional scepticism throughout the audit. We also:

• identify and assess the risks of material misstatement ofthe financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentionalomissions,misrepresentations, or the override of internal control;
• obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control;
• evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Company's Management Board.
• conclude on the appropriateness of the Company's Management Board's use of the

going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the Company to cease to continue as a going concern;

evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements representthe underlying transactions and events in a manner that achieves fair presentation.

We communicate with the Audit Committee regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide the Audit Committee with a statement that we have complied with relevant ethical requirements regardingindependence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, relatedsafeguards.

From the matters communicated to the Audit Committee, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor's report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.
