2. Basis of preparation

(a) Statement of compliance

These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRSs”).

(b) Basis of measurement

The consolidated ‍financial statements are prepared on the historical cost basis except for measurement of available-for-sale investments at fair value and certain other items when IFRS requires accounting treatment other than historical cost accounting (refer to Note 4).

(c) Functional and presentation currency

The national currency of the Russian Federation is the Russian Rouble (“RUB”), which is the functional currency of Group entities and the currency in which these consolidated ‍financial statements are presented. The only Group entity with other functional currency is GNC-Alfa, incorporated in Armenia. The functional currency of this entity is Armenian Dram (“AMD”). All financial information presented in RUB has been rounded to the nearest million, unless otherwise stated.

(d) Use of estimates and judgements

The preparation of financial statements in conformity with IFRSs requires management to make judgements, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimates are revised and in any future periods affected.

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below:

Changes in Estimate of Useful Lives

The Group assesses the remaining useful lives of items of property, plant and equipment at least at each financial year-end and, if expectations differ from previous estimates, the changes are accounted for as a change in an accounting estimate in accordance with IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors.

Fair Values of Associates

The Group is required to recognize the fair value of associates at the acquisition date, which involves estimates. Such estimates are based on valuation techniques, which require considerable judgement in forecasting future cash flows and developing other assumptions.

Share-based employee benefits

The Group measures cost of share-based employee benefit by reference to the fair value of equity instruments granted. This requires judgment in estimating future volatility of basis asset which is determined using historical data on market price of the shares. Future volatility may differ significantly from that estimated.

Employee Benefits

The Group uses actuarial valuation methods for measurement of the present value of defined employee benefit obligations and related current service cost. This involves the use of demographic assumptions about the future characteristics of current employees who are eligible for benefits (mortality, both during and after employment, rates of employee turnover, etc.) as well as financial assumptions (discount rate, future salary and benefit levels, etc.).


The Group makes allowances for doubtful accounts receivable. Significant judgment is used to estimate doubtful accounts. In estimating doubtful accounts historical and anticipated customer performance are considered. Changes in the economy, industry, or specific customer conditions may require adjustments to the allowance for doubtful accounts recorded in the consolidated financial statements.

Impairment of non-current assets

Each asset or cash generating unit is evaluated at the end of every reporting period to determine whether there are any indications of impairment. If any such indication exists, a formal estimate of the recoverable amount is performed and an impairment loss recognised to the extent that carrying amount exceeds the recoverable amount. For goodwill and intangible assets that have indefinite lives or that are not yet available for use, recoverable amount is estimated at each reporting date.

This requires an estimation of the value in use of the cash-generating units. Estimating of value in use requires the Group to make significant judgement concerning expected future cash flows and discount rates applicable. Expected future cash flows of cash-generating unit are typically based on approved budgets for next financial years and strategic plan for the period from second till fifth years. Cash flows beyond five–year periods are extrapolated using industry growth rate. Discount rates are determined based on historical information of cost of debt and equity of a respective cash-generating unit. Any future changes in the aforementioned assumptions could have significant impact on value in use.


The Group exercises considerable judgment in measuring and recognizing provisions and the exposure to contingent liabilities related to pending litigation or other outstanding claims subject to negotiated settlement, mediation, arbitration or government regulation, as well as other contingent liabilities. Judgment is necessary in assessing the likelihood that a pending claim will succeed, or a liability will arise, and to quantify the possible range of the final settlement. Because of the inherent uncertainties in this evaluation process, actual losses may be different from the originally estimated provision. These estimates are subject to change as new information becomes available. Revisions to the estimates may significantly affect future operating results.
