| (u) | Significant accounting judgments, estimates and assumptions |
The preparation of the consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported carrying amounts of assets and liabilities, and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the amounts of revenues and expenses recognised during the reporting period. Estimates and assumptions are continually evaluated and are based on the Group’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods.
Judgments
In the process of applying the Group’s accounting policies, management has made the following judgments, which have the most significant effect on the amount recognised in the consolidated financial statements.
Capitalization of interest related to the Elga Coal Deposit and Railway Construction
In 2013 and 2014, Elgaugol OOO (“Elgaugol”) and the Russian State Corporation “Bank for Development and Foreign Economic Affairs” (“VEB”) signed credit agreements for financing of the Elga coal project approved by the VEB’s Supervisory Board in September 2013. The use of proceeds under these facilities is limited to the development of the Elga coal project. Borrowing costs under these VEB facilities that are directly attributable to the construction of the Elga coal project are capitalized. Borrowing costs consist of interest including exchange differences arising from revaluation of foreign currency borrowings and other costs that the Group incurs in connection with the debt servicing.
Railway depreciation method
In 2015, the Group commenced to depreciate the railway of the Elga coal deposit using units of production method. In applying the units of production method, depreciation is normally calculated based on produced and delivered tonnes in the period as a percentage of total expected tonnes to be produced and delivered in current and future periods over the Elga coal deposit life cycle. The Group’s analysis has shown that the consumption of the economic benefits of the asset is linked to production and delivery of coal. The Group assesses the total or ultimate railway capacity in tonnes at least at each financial year end and, if expectations differ from previous estimates, the changes will be accounted for as a change in an accounting estimate in accordance with IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors.
DEMP property complex
On June 25, 2016, by the decree of the Council of Ministers of the self-proclaimed People’s Republic of Donetsk, the State Enterprise “Yuzovsky metallurgical plant” was established on the basis of the property complex of the Group’s subsidiary Donetsk Electrometallurgical Plant (“DEMP”). The Group’s ability to manage and control the assets of the DEMP property complex is restricted by this decree. The Group concluded that the assets included in the DEMP’s property complex do not meet the recognition criteria and derecognized these assets in the consolidated financial statements.
The DEMP’s assets were fully impaired based on the results of impairment tests as of January 1, 2014 and December 31, 2014 due to conservation of production since 2013. The loss of control over the assets of nil carrying value has no impact on the financial result for the years ended December 31, 2016 and 2017.
Principal vs agent arrangements
The Group makes significant judgment on gross or net revenue recognition. The Group evaluates the relevant facts and circumstances and takes into consideration the following factors in determining whether to recognize revenue on a gross basis:
| • | The Group has the primary responsibility for providing the goods or services to the customer or for fulfilling the order, for example by being responsible for the acceptability of the products or services ordered or purchased by the customer; |
| • | The Group has inventory risk before or after the customer order, during shipping or on return; |
| • | The Group has latitude in establishing prices, either directly or indirectly, for example by providing additional goods or services; and |
| • | The Group bears the customer’s credit risk for the amount receivable from the customer. |
Otherwise, revenues are reported net when the Group performs as an agent or a broker without assuming the risks and rewards of ownership of goods. The evaluations of these factors, which at times can be contradictory, are subject to significant judgment and subjectivity. In the situation when the Group acts as a supplier and as a buyer with the same counterparty, the Group analyzes the respective purchase and sales agreements to identify whether these transactions were concluded in contemplation with each other and, therefore, should be combined for accounting purposes deferring the revenue recognition to the point when the earnings process has culminated.
Estimates and assumptions
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 described below or in the related accounting policy note. The Group based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market change or circumstances arising beyond the control of the Group.
In particular, the Group has identified a number of areas where significant estimates and assumptions are required. Further information on each of these areas and how they impact the various accounting policies are described with the associated accounting policy note within the related qualitative and quantitative note as described below.
Deferred tax assets and uncertain tax positions
Deferred tax assets are recognised for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilised. Significant management judgment is required to determine the amount of deferred tax assets that can be recognised, based upon the likely timing and the level of future taxable profits and the existence of taxable temporary differences (Note 20). Various factors are considered to assess the probability of the future utilization of deferred tax assets for individual subsidiaries and for the consolidated group of taxpayers, including past operating results, operational plans for not longer than five years as this term is considered reliable and accurate for forecast, same assumptions for operational plans as used for determination of the expected future cash flows from the cash generating units, financial plans based on historical data and expectation built on the debt portfolio, terms of the expiration of tax losses carried forward depending on respective tax legislation, and tax planning strategies based on changes in tax regulation for tax losses offsetting for 2018-2020. If actual results differ from these estimates or if these estimates must be adjusted in future periods, the Group’s financial position, results of operations and cash flows may be affected. In the event that the assessment of future utilization of deferred tax assets must be changed, this effect is recognised in the consolidated statement of profit (loss) and other comprehensive income (loss).
The carrying amount of deferred tax assets is reviewed at each reporting date and is adjusted to reflect the likelihood that the estimated taxable profit and taxable temporary differences will be sufficient to recover the asset in whole or in part.
Impairment of property, plant and equipment and other non-current assets
The Group assesses at each reporting date whether there is any indication that an asset may be impaired. If any such indication exists, the Group makes an estimate of the asset’s recoverable amount. An impairment exists when the carrying value of an asset or CGU exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arm’s length for similar assets or observable market prices less incremental costs for disposing of the asset. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessment of the time value of money and the risks specific to the assets.
Impairment is based on a large number of factors, such as changes in current competitive conditions, expectations of growth in the industry, changes in cost of capital, changes in the future availability of financing, technological obsolescence, and other changes in circumstances that indicate that impairment exists. The determination of the recoverable amount of a cash-generating unit involves the use of estimates by management. Methods used to determine the value in use include discounted cash flow-based methods, which require the Group to make an estimate of the expected future cash flows from the cash-generating unit and also to choose a suitable discount rate in order to calculate the present value of those cash flows. These estimates, including the methodologies used, may have a material impact on the value in use and, ultimately, the amount of any impairment (Note 18).
Impairment of goodwill
The Group determines whether goodwill is impaired at least on an annual basis and when circumstances indicate that the carrying value may be impaired. This requires an estimation of the value in use of the cash generating units to which the goodwill is allocated. Estimating the value in use requires the Group to make an estimate of the expected future cash flows from the cash-generating unit and also to choose a suitable discount rate in order to calculate the present value of those cash flows. More details of the assumptions used in estimating the value in use of the cash-generating units to which goodwill is allocated are provided in Note 18.
Useful lives of items of property, plant and equipment
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. These estimates may have a material impact on the amount of the carrying values of property, plant and equipment and on depreciation expense for the period.
Mineral reserves
Mineral reserves and the associated mine plans are a material factor in the Group’s computation of a depletion charge. Estimation of reserves involves some degree of uncertainty. The uncertainty depends mainly on the amount of reliable geological and engineering data available at the time of the estimate and the interpretation of this data, which also requires use of subjective judgment and development of assumptions. Mine plans are periodically updated which can have a material impact on the depletion charge for the period. More details are provided in Note 3(i).
Fair value of financial instruments
Where the fair value of financial assets and financial liabilities recorded in the consolidated statement of financial position cannot be derived from active markets, their fair value is determined using valuation techniques, including discounted cash flow models and other specific models. The inputs to these models are taken from observable markets where possible, but when these are not available, a degree of judgment is required in establishing fair values. The judgments include considerations of inputs such as dividend yield, terms of redemption, liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments (Note 10).
Provisions
The Group is subject to various legal proceedings, disputes and claims, including regulatory discussions related to the Group’s business, licenses, tax positions and the outcomes are subject to significant uncertainty. Management evaluates, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Unanticipated events or changes in these factors may require the Group to increase or decrease the amount recorded or to be recorded for a matter that has not been previously recorded because it was not considered probable (Note 23).
Pensions and other post-employment benefits
The cost of defined benefit pension plans and other post-employment benefits and the present value of the pension obligation are determined using actuarial valuations. An actuarial valuation involves making various assumptions which may differ from actual developments in the future. These include the determination of the discount rate, future salary increases, mortality rates and future pension increases. Due to the complexity of the valuation, the underlying assumptions and its long-term nature, a defined benefit obligation and other long-term benefit plans are highly sensitive to changes in these assumptions. All assumptions are reviewed at each reporting date. More details are provided in Note 22.
Rehabilitation provisions
The Group reviews rehabilitation provisions at each reporting date and adjusts them to reflect the current best estimate. Rehabilitation provisions are recognised in the period in which they arise and are stated at the best estimate of the present value of estimated future costs. These estimates require extensive judgment about the nature, cost and timing of the work to be completed, and may change with future changes to costs, environmental laws and regulations and remediation practices. Changes in the estimated timing of rehabilitation or changes to the estimated future costs are dealt with prospectively by recognizing an adjustment to the rehabilitation provision and a corresponding adjustment to the asset to which it relates, if the initial estimate was originally recognised as part of an asset measured in accordance with IAS 16 Property, Plant and Equipment (Note 16).
Impairment of financial assets
The Group makes allowances for doubtful receivables to account for estimated losses resulting from the inability of customers to make required payments. When evaluating the adequacy of an allowance for doubtful accounts, management bases its estimates on the current overall economic conditions, the ageing of accounts receivable balances, historical write-off experience, customer creditworthiness and changes in payment terms. Changes in the economy, industry or specific customer conditions may require adjustments to the allowance for doubtful accounts recorded in the consolidated financial statements (Note 13).
Determining net realizable value of inventories
The Group makes write-downs for obsolete and slow-moving raw materials and spare parts. In addition, finished goods of the Group are carried at net realizable value (Note 12). Estimates of net realizable value of finished goods are based on the most reliable evidence available at the time the estimates are made. These estimates take into consideration fluctuations of price or cost directly relating to events occurring subsequent to the end of the reporting period to the extent that such events confirm conditions existing at the end of the period.
