Independent auditor's report

To the Shareholders and Board of Directorsof Rosneft Oil Company

Opinion

We have audited the consolidated financial statements of Public Joint Stock Company Rosneft Oil Company and its subsidiaries (hereinafter collectively referred to as the "Company"), which comprise the consolidated balance sheet as at December 31, 2017, and the consolidated statement of profit or loss, consolidated statement of other comprehensive income, consolidated statement of changes in shareholder's equity and consolidated statement of cash flows for the year then ended, and notes to the consolidated financial statements, including a summary of significant accounting policies.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as at December 31, 2017, and its consolidated financial performance and its consolidated cash flows for the year then ended in accordance with International Financial Reporting Standards (IFRSs).

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (ISAs). Our responsibilities under those standards are further described in the Auditor's responsibilities for the audit of the consolidated financial statements section of our report. We are independent of the Company in accordance with the International Ethics Standards Board for Accountants' Code of Ethics for Professional Accountants (IESBA Code) together with the ethical requirements that are relevant to our audit of the consolidated financial statements in the Russian Federation, and we have fulfilled our other ethical responsibilities in accordance with these requirements and the IESBA Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key audit matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. For each matter below, our description of how our audit addressed the matter is provided in that context.

We have fulfilled the responsibilities described in the Auditor's responsibilities for the audit of the consolidated financial statements section of our report, including in relation to these matters. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the consolidated financial statements. The results of our audit procedures, including the procedures performed to address the matters below, provide the basis for our audit opinion on the accompanying consolidated financial statements.

Other matter

The information accompanying the consolidated financial statements which has been disclosed as Supplementary oil and gas disclosure on page 87 is presented for purposes of additional analysis and is not within the scope of IFRS. Such information has not been subjected to the auditing procedures applied in our audit of the consolidated financial statements and, accordingly, we do not express an opinion on it.

Other information included in the Management's discussion and analysis of financial condition and results of operations and Annual report

Other information comprises the Management's discussion and analysis of financial condition and results of operations for 2017 (but does not include the consolidated financial statements and our auditor's report thereon), which we obtained prior to the date of this auditor's report, and the 2017 Annual report, which is expected to be made available to us after that date. Management is responsible for the other information.

Our opinion on the consolidated financial statements does not cover the other information and we do not and will not express any form of assurance conclusion thereon.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information identified above and, in doing so, consider whether the other information is materially inconsistent with the consolidated financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed on the other information obtained prior to the date of the auditor's report, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

Responsibilities of management and the Audit Committee of the Board of Directors for the consolidated financial statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with IFRSs, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management 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 management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

The Audit Committee of the Board of Directors are responsible for overseeing the Company's financial reporting process.

Auditor's responsibilities for the audit of the consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the consolidated 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 ISAs will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with ISAs, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the consolidated 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, intentional omissions, 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 management.

• Conclude on the appropriateness of management'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 consolidated 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 consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

• Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

We communicate with the Audit Committee of the Board of Directors 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 of the Board of Directors with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with the Audit Committee of the Board of Directors, we determine those matters that were of most significance in the audit of the consolidated 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.

The partner in charge of the audit resulting in this independent auditor's report is Konstantin I. Petrov.

1. General

Public Joint Stock Company ("PJSC") Rosneft Oil Company ("Rosneft") and its subsidiaries (collectively, the "Company") are principally engaged in exploration, development, production and sale of crude oil and gas and refining, transportation and sale of petroleum products in the Russian Federation and in certain international markets.

Rosneft State Enterprise was incorporated as an open joint stock company on December 7, 1995. All assets and liabilities previously managed by Rosneft State Enterprise were transferred to the Company at their book value effective on that date together with ownership rights to other privatized oil and gas companies belonging to the Government of the Russian Federation (the "State"). The transfer of assets and liabilities was made in accordance with Russian Government Resolution No. 971 dated September 29, 1995, On the Transformation of Rosneft State Enterprise into Open Joint Stock Company "Oil Company Rosneft". These transfers involved the reorganization of assets under the common control of the State and, accordingly, were accounted for at their book value. In 2005, the State contributed the shares of Rosneft to the share capital of JSC ROSNEFTEGAS. As of December 31, 2005, 100% of the shares of Rosneft less one share were owned by JSC ROSNEFTEGAS and one share was owned by the Russian Federation Federal Agency for the Management of Federal Property. Subsequently, JSC ROSNEFTEGAS's ownership interest decreased through the additional issue of shares during Rosneft's Initial Public Offering ("IPO") in Russia, an issue of Global Depository Receipts ("GDR") for shares on the London Stock Exchange and the share swap completed during the merger of Rosneft and certain subsidiaries in 2006. In March 2013 in the course of the acquisition of TNK-BP Limited and TNK Industrial Holdings Limited, its subsidiary (collectively with their subsidiaries, "TNK-BP"), JSC ROSNEFTEGAS sold 5.66% of Rosneft shares to BP plc. ("BP"). In December 2016 JSC ROSNEFTEGAS signed an agreement to sell 19.5% of Rosneft shares to a consortium of foreign investors. As of December 31, 2017 JSC ROSNEFTEGAS's ownership interest in Rosneft amounted to 50% plus one share.

Under Russian legislation, natural resources, including oil, gas, precious metals and minerals and other commercial minerals situated in the territory of the Russian Federation, are the property of the State until they are extracted. Law of the Russian Federation No. 2395-1, On Subsurface Resources, regulates relations arising in connection with the geological study, use and protection of subsurface resources in the territory of the Russian Federation. Pursuant to the law, subsurface resources may be developed only on the basis of a license. A license is issued by the regional governmental body and contains information on the site to be developed and the period of activity, as well as financial and other conditions. The Company holds licenses issued by competent authorities for the geological study, exploration and development of oil and gas blocks, fields, and shelf in areas where its subsidiaries are located.

The Company is subject to export quotas set by the Russian Federation State Pipeline Commission to allow equal access to the limited capacity of the oil pipeline system owned and operated by PJSC AK Transneft. The Company exports certain quantities of crude oil through bypassing the PJSC AK Transneft system thus achieving higher export capacity. The remaining production is processed at the Company's and third parties' refineries for further sale on domestic and international markets.

2. Basis of preparation

These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, including all International Financial Reporting Standards ("IFRS") and Interpretations issued by the International Accounting Standards Board ("IASB") and effective in the reporting period, and are fully compliant therewith.

These consolidated financial statements have been prepared on a historical cost basis, except certain financial assets and liabilities measured at fair value (Note 37).

Rosneft and its subsidiaries maintain their books and records in accordance with statutory accounting and taxation principles and practices applicable in respective jurisdictions. These consolidated financial statements were derived from the Company's statutory books and records.

The Company's consolidated financial statements are presented in billions of Russian rubles ("RUB"), unless otherwise indicated.

The consolidated financial statements were approved and authorized for issue by the Chief Executive Officer of the Company on March 19, 2018.

Subsequent events have been evaluated through March 19, 2018, the date these consolidated financial statements were issued.

3. Significant accounting policies

The accompanying consolidated financial statements differ from the financial statements issued for statutory purposes in that they reflect certain adjustments, not recorded in the Company's statutory books, which are appropriate for presenting the financial position, results of operations and cash flows in accordance with IFRS. The principal adjustments relate to: (1) recognition of certain expenses; (2) valuation and depreciation of property, plant and equipment; (3) deferred income taxes; (4) valuation allowances for unrecoverable assets; (5) accounting for the time value of money; (6) accounting for investments in oil and gas property and conveyances; (7) consolidation principles; (8) recognition and disclosure of guarantees, contingencies, commitments and certain assets and liabilities; (9) business combinations and goodwill; (10) accounting for derivative instruments; (11) purchase price allocation to the identifiable assets acquired and the liabilities assumed.

The consolidated financial statements include the accounts of majority-owned, controlled subsidiaries and special-purpose entities where the Company holds a beneficial interest. All significant intercompany transactions and balances have been eliminated. The equity method is used to account for investments in associates in which the Company has the ability to exert significant influence over the associates' operating and financial policies. Investments in entities where the Company holds the majority of shares, but does not exercise control, are also accounted for using the equity method. Investments in other companies are accounted for at fair value or cost adjusted for impairment, if any.

Business combinations, goodwill and other intangible assets

Acquisitions by the Company of controlling interests in third parties (or interest in their charter capital) are accounted for using the acquisition method.

The date of acquisition is the date when effective control over the acquiree passes to the Company.

3. Significant accounting policies (continued)

Business combinations, goodwill and other intangible assets (continued)

The cost of an acquisition is measured as an aggregate of the consideration transferred, measured at acquisition date fair value, and the amount of any non-controlling interest in the acquiree. For each business combination, the Company elects whether it measures the non-controlling interest in the acquiree either at fair value or at the proportionate share of the acquiree's identifiable net assets. Acquisition costs incurred are expensed and included in administrative expenses.

Any contingent consideration to be transferred by the acquirer is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration which is deemed to be an asset or a liability should be recognized within profit or loss for the period if they do not represent measurement-period adjustments. If the contingent consideration is classified as equity, it should not be re-measured.

Goodwill is initially measured at cost being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling interests over the fair value of net identifiable assets acquired and liabilities assumed. If the aggregate of the consideration transferred and the amount of non-controlling interest is lower than the fair value of the net assets of the subsidiary acquired and liabilities assumed, the difference is recognized in profit or loss for the period.

Associates

Investments in associates are accounted for using the equity method unless they are classified as non-current assets held for sale. Under this method, the carrying value of investments in associates is initially recognized at the acquisition cost.

The carrying value of investments in associates is increased or decreased by the Company's reported share in the profit or loss and other comprehensive income of the investee after the acquisition date. The Company's share in the profit or loss and other comprehensive income of an associate is recognized in the Company's consolidated statement of profit or loss or in the consolidated statement of other comprehensive income, respectively. Dividends paid by the associate are accounted for as a reduction of the carrying value of investments.

The Company's net investments in associates include the carrying value of the investments in these associates as well as other long-term investments that are, in substance, investments in associates, such as loans. If the share in losses exceeds the carrying value of the investments in associates and the value of other long-term investments related to investments in these associates, the Company ceases to recognize its share in losses when the carrying value reaches zero. Any additional losses are provided for and liabilities are recognized only to the extent that the Company has legal or constructive obligations or has made payments on behalf of the associate.

If the associate subsequently makes profits, the Company resumes recognizing its share in these profits only after its share of the profits equals the share of losses not recognized.

The carrying value of investments in associates is tested for impairment by reconciling its recoverable amount (the higher of its value in use and fair value less costs to sell) to its carrying value, whenever impairment indicators are identified.

3. Significant accounting policies (continued)

Joint arrangements

The Company participates in joint arrangements either in the form of joint ventures or joint operations.

A joint venture implies that the parties that have joint control of the arrangement have rights to the net assets of the arrangement. A joint venture involves establishing a legal entity where the Company and other participants have respective equity interests. Equity interests in joint ventures are accounted for under the equity method.

The Company's share in net profit or loss and in other comprehensive income of joint ventures is recognized in the consolidated statement of profit or loss and in the consolidated statement of other comprehensive income, respectively, from the date when joint control commences until the date when joint control ceases. A joint operation implies that the parties that have joint control of the arrangement have rights to the assets, and obligations for the liabilities, relating to the arrangement. In relation to its interest in a joint operation the Company recognizes its assets, including its share of any assets held jointly, its liabilities, including its share of any liabilities incurred jointly, its revenue from the sale of its share of the output arising from the joint operation, its share of the revenue from the sale of the output by the joint operation, and expenses, including its share of any expenses incurred jointly.

Cash and cash equivalents

Cash represents cash on hand, in the Company's bank accounts, in transit and interest bearing deposits which can be effectively withdrawn at any time without prior notice or any penalties reducing the principal amount of the deposit. Cash equivalents are highly liquid, short-term investments that are readily convertible to known amounts of cash and have original maturities of three months or less from their date of purchase. They are carried at cost plus accrued interest, which approximates fair value. Restricted cash is presented separately in the consolidated balance sheet if its amount is significant.

Financial assets

The Company recognizes financial assets in its balance sheet when, and only when, it becomes a party to the contractual provisions of the financial instrument. When financial assets are recognized initially, they are measured at fair value, which is usually the price of the transaction, i.e. the fair value of consideration paid or received.

When financial assets are recognized initially, they are classified as one of the following, as appropriate: (1) financial assets at fair value through profit or loss, (2) loans issued and accounts receivable, (3) financial assets held to maturity, or (4) financial assets available for sale.

Financial assets at fair value through profit or loss include financial assets held for trading and financial assets designated as financial assets at fair value through profit or loss at initial recognition. Financial assets held for trading are those which are acquired principally for the purpose of sale or repurchase in the near future or are part of a portfolio of identifiable financial instruments that have been commonly managed and for which there is evidence of a recent pattern of actual short-term profit taking, or which are derivative instruments (unless the derivative instrument is defined as an effective hedging instrument). Financial assets at fair value through profit or loss are classified in the consolidated balance sheet as current assets and changes in the fair value are recognized in the consolidated statement of profit or loss as Finance income or Finance expenses.

3. Significant accounting policies (continued)

Financial assets (continued)

All derivative instruments are recorded in the consolidated balance sheet at fair value in either current financial assets, non-current financial assets, current liabilities related to derivative instruments, or non-current liabilities related to derivative instruments. The recognition and classification of a gain or loss that results from recognition of an adjustment of a derivative instrument at fair value depends on the purpose for issuing or holding the derivative instrument. Gains and losses from derivatives that are not accounted for as hedges under International Accounting Standard ("IAS") 39 Financial Instruments: Recognition and Measurement are recognized immediately in the profit or loss for the period.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Subsequent to initial recognition, the fair value of financial assets at fair value that are quoted in an active market is defined as bid prices for assets and ask prices for issued liabilities as of the measurement date.

If no active market exists for financial assets, the Company measures the fair value using the following methods:

· analysis of recent transactions with peer instruments between independent parties;

· current fair value of similar financial instruments;

· discounting future cash flows.

The discount rate reflects the minimum return on investment an investor is willing to accept before starting an alternative project, given its risk and the opportunity cost of forgoing other projects.

Loans issued and accounts receivable include non-derivative financial instruments with fixed or determinable payments that are not quoted in an active market, not classified as financial assets held for trading and have not been designated as at fair value through profit or loss or available for sale. If the Company cannot recover all of its initial investment in the financial asset due to reasons other than deterioration of its quality, the financial asset is not included in this category. After initial recognition, loans issued and accounts receivable are measured at amortized cost using the effective interest rate method ("EIR"), less impairment losses. The EIR amortization is included in Finance income in the consolidated statement of profit or loss. The losses arising from impairment or gains from impairment reversals are recognized in the consolidated statement of profit or loss.

The Company does not classify financial assets as held to maturity if, during either the current financial year or the two preceding financial years, the Company has sold, transferred or exercised a put option on more than an insignificant (in relation to the total) amount of such investments before maturity, unless: (1) the financial asset was close enough to maturity or the call date so that changes in the market rate of interest did not have a significant effect on the financial asset's fair value; (2) after substantially all of the financial asset's original principal had been collected through scheduled payments or prepayments; or (3) due to an isolated non-recurring event that was beyond the Company's control and could not have been reasonably anticipated by the Company.

Dividends and interest income are recognized in the consolidated statement of profit or loss on an accrual basis. The amount of accrued interest income is calculated using the effective interest rate.

All other financial assets not included in the other categories are designated as financial assets available for sale. Specifically, the shares of other companies not included in the first category are designated as available for sale. In addition, the Company may include any financial asset in this category at the initial recognition.

3. Significant accounting policies (continued)

Financial liabilities

The Company recognizes financial liabilities on its balance sheet when, and only when, it becomes a party to the contractual provisions of the financial instrument. When financial liabilities are recognized initially, they are measured at fair value, which is usually the price of the transaction, i.e. the fair value of consideration paid or received.

When financial liabilities are recognized initially, they are classified as one of the following:

· financial liabilities at fair value through profit or loss;

· other financial liabilities.

Financial liabilities at fair value through profit or loss are financial liabilities held for trading unless such liabilities are linked to the delivery of unquoted equity instruments.

At the initial recognition, the Company may include in this category any financial liability, except for equity instruments that are not quoted in an active market and whose fair value cannot be reliably measured. After initial recognition, however, the liability cannot be reclassified.

Financial liabilities not classified as financial liabilities at fair value through profit or loss are designated as other financial liabilities. Other financial liabilities include, inter alia, trade and other accounts payable, and loans and borrowings payable.

Subsequent to initial recognition, financial liabilities at fair value through profit or loss are measured at fair value, with changes in fair value recognized in profit or loss in the consolidated statement of profit or loss. Other financial liabilities are carried at amortized cost.

The Company writes off a financial liability (or part of a financial liability) from its balance sheet when, and only when, it is extinguished - i.e. when the obligation specified in the contract is discharged, cancelled or expires. The difference between the carrying value of a financial liability (or a part of a financial liability) extinguished or transferred to another party and the redemption value, including any transferred non-monetary assets and assumed liabilities, is recognized in profit or loss. Any previously recognized components of other comprehensive income pertaining to this financial liability are also included in the financial result and are recognized as gains and losses for the period.

Certain prior period indicators have been reclassified to conform to the current year presentation. In particular, due to significant increase in the operating activities of subsidiary banks of the Company and the need for reliable and consistent reporting in the consolidated financial statements, the presentation of cash flows from the operating activities of subsidiary banks was revised. Such activities are now included within operating activities of the Consolidated Statement of Cash Flows. Further, the operating assets of the subsidiary banks, including short-term interbank deposits placed, were reclassified to Accounts Receivable, operating liabilities, including interbank loans, customer deposits, promissory notes and REPO obligations reclassified from Loans and borrowings and other financial liabilities to Accounts payable and accrued liabilities.

Earnings per share

Basic earnings per share is calculated by dividing net earnings attributable to common shares by the weighted average number of common shares outstanding during the corresponding period. In the absence of any securities-to-shares conversion transactions, the amount of basic earnings per share stated in these consolidated financial statements is equal to the amount of diluted earnings per share.

3. Significant accounting policies (continued)

Inventories

Inventories consisting primarily of crude oil, petroleum products, petrochemicals and materials and supplies are accounted for at the weighted average cost unless net realizable value is less than cost. Materials that are used in production are not written down below cost if the finished products into which they will be incorporated are expected to be sold above cost.

Repurchase and resale agreements

Securities sold under repurchase agreements ("REPO") and securities purchased under agreements to resell ("reverse REPO") generally do not constitute a sale of the underlying securities for accounting purposes, and so are treated as collateralized financing transactions. Interest paid or received on all REPO and reverse REPO transactions is recorded in Finance expense or Finance income, respectively, at the contractually specified rate using the effective interest method.

Exploration and production assets

Exploration and production assets include exploration and evaluation assets, mineral rights and oil and gas properties (development assets and production assets).

Exploration and evaluation costs

The Company recognizes exploration and evaluation costs using the successful efforts method as permitted by IFRS 6 Exploration for and Evaluation of Mineral Resources. Under this method, costs related to exploration and evaluation (license acquisition costs, exploration and appraisal drilling) are temporarily capitalized in cost centers by field (well) until the drilling program results in the discovery of economically feasible oil and gas reserves.

The length of time necessary for this determination depends on the specific technical or economic difficulties in assessing the recoverability of the reserves. If a determination is made that the well did not encounter oil and gas in economically viable quantities, the well costs are expensed to Exploration expenses in the consolidated statement of profit or loss.

Exploration and evaluation costs, except for costs associated with seismic, topographical, geological, and geophysical surveys, are initially capitalized as exploration and evaluation assets. Exploration and evaluation assets are recognized at cost less impairment, if any, as property, plant and equipment until the existence (or absence) of commercial reserves has been established. The initial cost of exploration and evaluation assets acquired through a business combination is formed as a result of purchase price allocation. The cost allocation to mineral rights to proved properties and mineral rights to unproved properties is performed based on the respective oil and gas reserves information. Exploration and evaluation assets are subject to technical, commercial and management review as well as review for indicators of impairment at least once a year. This is to confirm the continued intent to develop or otherwise extract value from the discovery. When indicators of impairment are present, an impairment test is performed.

If, subsequently, commercial reserves are discovered, the carrying value, less losses from impairment of the respective exploration and evaluation assets, is classified as oil and gas properties (development assets). However, if no commercial reserves are discovered, such costs are expensed after exploration and evaluation activities have been completed.

3. Significant accounting policies (continued)

Development and production

Oil and gas properties (development assets) are accounted for on a field-by-field basis and represent (1) capitalized costs to develop discovered commercial reserves and to put fields into production, and (2) exploration and evaluation costs incurred to discover commercial reserves reclassified from exploration and evaluation assets to oil and gas properties (development assets) following the discovery of commercial reserves.

The cost of oil and gas properties (development assets) also includes the expenditures to acquire such assets, directly identifiable overhead expenses, capitalized financing costs and related asset retirement (decommissioning) obligation costs. Oil and gas properties (development assets) are generally recognized as construction in progress.

Following the commencement of commercial production, oil and gas properties (development assets) are reclassified as oil and gas properties (production assets).

Other property, plant and equipment

Other property, plant and equipment is stated at historical cost as of the acquisition date, except for property, plant and equipment acquired prior to January 1, 2009, which is stated at deemed cost, net of accumulated depreciation and impairment. The cost of maintenance, repairs, and the replacement of minor items of property is charged to operating expenses. Renewals and betterments of assets are capitalized.

Upon the sale or retirement of property, plant and equipment, the cost and related accumulated depreciation are eliminated from the accounts. Any resulting gains or losses are included in profit or loss.

Depreciation, depletion and amortization

Oil and gas properties are depleted using the unit-of-production method on a field-by-field basis starting from the commencement of commercial production.

In applying the unit-of-production method to mineral licenses, the depletion rate is based on total proved reserves. In applying the unit-of-production method to producing wells and the related oil and gas infrastructure, the depletion rate is based on proved developed reserves.

Other property, plant and equipment are depreciated using the straight-line method over their estimated useful lives from the time they are ready for use, except for catalysts which are amortized using the unit-of-production method.

Components of other property, plant and equipment and their respective estimated useful lives are as follows:

Land generally has an indefinite useful life and is therefore not depreciated.

Land leasehold rights are amortized on a straight-line basis over their expected useful life, which averages 20 years.

3. Significant accounting policies (continued)

Construction grants

The Company recognizes construction grants from local governments when there is a reasonable assurance that the Company will comply with the conditions attached and that the grant will be received. The construction grants are accounted for as a reduction of the cost of the asset for which the grant is received.

Impairment of non-current assets

The Company assesses at each balance sheet date whether there is any indication that an asset or cash-generating unit may be impaired. If any such indication exists, the Company estimates the recoverable amount of the asset or cash-generating unit.

In assessing whether there is any indication that an asset may be impaired, the Company considers internal and external sources of information. It considers at least the following:

External sources of information:

· during the period, an asset's market value has declined significantly more than would be expected as a result of the passage of time or normal use;

· significant changes with an adverse effect on the Company have taken place during the period, or will take place in the near future, in the technological, market, economic or legal environment in which the Company operates or in the market to which an asset is dedicated;

· market interest rates or other market rates of return on investments have increased during the period, and those increases are likely to affect the discount rate used in calculating an asset's value in use and decrease the asset's recoverable amount materially;

· the carrying amount of the net assets of the Company is more than its market capitalization.

Internal sources of information:

· evidence is available of obsolescence or physical damage of an asset;

· significant changes with an adverse effect on the Company have taken place during the period, or are expected to take place in the near future, in the extent to which, or manner in which, an asset is used or is expected to be used (e.g., the asset becoming idle, or the useful life of an asset is reassessed as finite rather than indefinite);

· information on dividends from a subsidiary, joint venture or associate;

· evidence is available from internal reporting that indicates that the economic performance of an asset is, or will be, worse than expected. Such evidence includes the existence of:

· cash flows on acquiring the asset, or subsequent cash needs for operating or maintaining it, that are significantly higher than those originally budgeted;

· actual net cash flows or operating profit or loss flowing from the asset that are significantly worse than those budgeted;

· a significant decline in budgeted net cash flows or operating profit, or a significant increase in budgeted losses, flowing from the asset;

· operating losses or net cash outflows for the asset, when current period amounts are aggregated with budgeted amounts for the future.

3. Significant accounting policies (continued)

Impairment of non-current assets (continued)

The following factors indicate that exploration and evaluation assets may be impaired:

· the period for which the Company has the right to explore in the specific area has expired during the period or will expire in the near future, and is not expected to be renewed;

· substantive expenditure on further exploration for and evaluation of mineral resources in the specific area is neither budgeted nor planned;

· exploration for and evaluation of mineral resources in the specific area have not led to the discovery of commercially viable quantities of mineral resources and the Company has decided to discontinue such activities in the specific area;

· sufficient data exist to indicate that, although a development in the specific area is likely to proceed, the carrying amount of the exploration and evaluation asset is unlikely to be recovered in full from successful development or by sale.

The recoverable amount of an asset or a cash-generating unit is the higher of:

· the value in use of an asset (cash-generating unit); and

· the fair value of an asset (cash-generating unit) less costs to sell.

If the asset does not generate cash inflows that are largely independent of those from other assets, its recoverable amount is determined for the asset's cash-generating unit.

The Company initially measures the value in use of a cash-generating unit. When the carrying amount of a cash-generating unit is greater than its value in use, the Company measures the unit's fair value for the purpose of measuring the recoverable amount. When the fair value is less than the carrying value an impairment loss is recognized.

Value in use is determined by discounting the estimated value of the future cash inflows expected to be derived from the asset or cash-generating unit, including cash inflows from its sale. The value of the future cash inflows from a cash-generating unit is determined based on the forecast approved by management of the business unit to which the unit in question pertains.

Impairment of financial assets

At each balance sheet date the Company analyzes whether there is objective evidence of impairment for all categories of financial assets, except those recorded at fair value through profit or loss. A financial asset or a group of financial assets is deemed to be impaired if there is objective evidence of impairment as a result of one or more events that has occurred since the initial recognition of the asset (an incurred 'loss event') and that loss event has an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated. Evidence of impairment may include (but is not limited to) indications that debtors or a group of debtors are experiencing financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization and observable data indicating that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.

3. Significant accounting policies (continued)

Capitalized interest

Interest expense on borrowed funds used for capital construction projects and the acquisition of property, plant and equipment is capitalized provided that the interest expense could have been avoided if the Company had not made capital investments. Interest is capitalized only during the period when construction activities are actually in progress and until the resulting properties are put into operation.

Capitalized borrowing costs include exchange differences arising from foreign currency borrowings to the extent that they are regarded as an adjustment to interest costs.

Leasing agreements

Leases, which transfer to the Company substantially all the risks and benefits incidental to ownership of the asset, are classified as financial leases and are capitalized at the commencement of the lease at the fair value of the leased property or, if lower, at the present value of the minimum lease payments. Lease payments are apportioned between the finance expenses and reduction of the lease liability in order to achieve a constant rate of interest on the remaining balance of the liabilities. Finance expenses are charged directly to the consolidated statement of profit or loss.

Leased property, plant and equipment are accounted for using the same policies applied to the Company's own assets. In determining the useful life of a leased item of property, plant and equipment, consideration is given to the probability of the title being transferred to the lessee at the end of the lease term.

If there is no reasonable certainty that the lessee will obtain ownership by the end of the lease term, the asset shall be fully depreciated over the shorter of the lease term and its useful life. Where such certainty exists, the asset is depreciated over its useful life.

Leases where the lessor retains substantially all the risks and benefits of ownership of the asset are classified as operating leases. Operating lease payments are recognized as an expense in the consolidated statement of profit or loss on a straight-line basis over the lease term.

Asset retirement (decommissioning) obligations

The Company has asset retirement (decommissioning) obligations associated with its core business activities. The nature of the assets and potential obligations are as follows:

The Company's exploration, development and production activities involve the use of wells, related equipment and operating sites, oil gathering and treatment facilities, tank farms and in-field pipelines. Generally, licenses and other regulatory acts require that such assets be decommissioned upon the completion of production. According to these requirements, the Company is obliged to decommission wells, dismantle equipment, restore the sites and perform other related activities. The Company's estimates of these obligations are based on current regulatory or license requirements, as well as actual dismantling and other related costs. These liabilities are measured by the Company using the present value of the estimated future costs of decommissioning of these assets. The discount rate is reviewed at each reporting date and reflects current market assessments of the time value of money and the risks specific to the liability.

3. Significant accounting policies (continued)

Asset retirement (decommissioning) obligations (continued)

In accordance with IFRS Interpretations Committee ("IFRIC") Interpretation 1 Changes in Existing Decommissioning, Restoration and Similar Liabilities, the provision is reviewed at each balance sheet date as follows:

· upon changes in the estimates of future cash flows (e.g., the costs of and timeframe for abandoning one well) or the discount rate, changes in the amount of the liability are included in the cost of the item of property, plant, and equipment, whereby such cost may not be negative and may not exceed the recoverable value of the item of property, plant, and equipment;

· any changes in the liability due to its nearing maturity (change in the discount) are recognized in Finance expenses.

The Company's refining and distribution activities involve refining operations, marine and other distribution terminals, and retail sales. The Company's refining operations consist of major petrochemical operations and industrial complexes. Legal or contractual asset retirement (decommissioning) obligations related to petrochemical, oil refining and distribution activities are not recognized due to the limited history of such activities in these segments, the lack of clear legal requirements as to the recognition of obligations, as well as the fact that decommissioning periods for such assets are not determinable.

Because of the reasons described above, the fair value of an asset retirement (decommissioning) obligation in the refining and distribution segment cannot be reasonably estimated.

Due to continuous changes in the Russian regulatory and legal environment, there could be future changes to the requirements and contingencies associated with the retirement of long-lived assets.

Income tax

Since 2012 Russian tax legislation has allowed income taxes to be calculated on a consolidated basis. The main subsidiaries of the Company were therefore combined into a consolidated group of taxpayers (Note 40). For subsidiaries which are not included in the consolidated group of taxpayers, income tax is calculated on an individual subsidiary basis. Deferred income tax assets and liabilities are recognized in the accompanying consolidated financial statements in the amount determined by the Company in accordance with IAS 12 Income Taxes.

Deferred tax is provided using the liability method on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.

A deferred tax liability is recognized for all taxable temporary differences, except to the extent that the deferred tax liability arises from:

· the initial recognition of goodwill;

· the initial recognition of an asset or liability in a transaction which:

· is not a business combination; and

· affects neither accounting profit, nor taxable profit;

· investments in subsidiaries when the Company is able to control the timing of the reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future.

3. Significant accounting policies (continued)

Income tax (continued)

A prior period tax loss planned to be used to reduce the current or future amount of income tax is recognized as a deferred tax asset.

A deferred tax asset is recognized only to the extent that it is probable that taxable profit will be available against which the deductible temporary differences can be utilized, unless the deferred tax asset arises from the initial recognition of an asset or liability in a transaction that:

· is not a business combination; and

· at the time of the transaction, affects neither accounting profit nor taxable profit (tax loss).

The Company recognizes deferred tax assets for all deductible temporary differences arising from investments in subsidiaries and associates, and interests in joint ventures, to the extent that the following two conditions are met:

· the temporary difference will reverse in the foreseeable future; and

· taxable profit will be available against which the temporary difference can be utilized.

Deferred tax assets and liabilities shall be measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period.

The measurement of deferred tax assets and liabilities reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the taxation authority of the same jurisdiction and the Company intends to settle its current tax assets and liabilities on a net basis.

The carrying amount of a deferred tax asset is reviewed at each balance sheet date.

The Company reduces the carrying amount of a deferred tax asset to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized.

Deferred tax assets and liabilities are classified as Non-current Deferred tax assets and Non-current Deferred tax liabilities, respectively.

Deferred tax assets and liabilities are not discounted.

Recognition of revenues

Revenues are recognized when risks and rewards pass to the customer, which usually occurs when the title passes to the customer, provided that the contract price is fixed or determinable and collectability of the receivable is reasonably assured. Specifically, domestic sales of crude oil and gas, as well as petroleum products and materials are usually recognized when title passes. For export sales, title generally passes at the border of the Russian Federation and the Company covers transportation expenses (except freight), duties and taxes on those sales (Note 10). Revenue is measured at the fair value of the consideration received or receivable taking into account the amount of any trade discounts, volume rebates and reimbursable taxes.

Sales of support services are recognized as services are performed provided that the service price can be determined and no significant uncertainties regarding the receipt of revenues exist.

3. Significant accounting policies (continued)

Transportation expenses

Transportation expenses recognized in the consolidated statement of profit or loss represent all expenses incurred by the Company to transport crude oil for refining and to end customers, and to deliver petroleum products from refineries to end customers (these may include pipeline tariffs and any additional railroad transportation costs, handling costs, port fees, sea freight and other costs).

Refinery maintenance costs

The Company recognizes the costs of overhauls and preventive maintenance performed with respect to oil refining assets as expenses when incurred.

Environmental liabilities

Expenditures that relate to an existing condition caused by past operations, and do not have a future economic benefit, are expensed. Liabilities for these expenditures are recorded when environmental assessments or clean-ups are probable and the costs can be reasonably estimated.

Accounting for contingencies

Certain conditions may exist as of the date of these consolidated financial statements which may further result in a loss to the Company, but which will only be resolved when one or more future events occur or fail to occur. The Company's management makes an assessment of such contingent liabilities which is based on assumptions and is a matter of opinion. In assessing loss contingencies relating to legal or tax proceedings that involve the Company or unasserted claims that may result in such proceedings, the Company, after consultation with legal or tax advisors, evaluates the perceived merits of any legal or tax proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein.

If the assessment of a contingency indicates that it is probable that a loss will be incurred and the amount of the liability can be estimated, then the estimated liability is accrued in the Company's consolidated financial statements. If the assessment indicates that a potentially material loss contingency is not probable, but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, would be disclosed.

Loss contingencies considered remote are generally not disclosed unless they involve financial guarantees, in which case the nature of the guarantee would be disclosed. However, in some instances in which disclosure is not otherwise required, the Company may disclose contingent liabilities or other uncertainties of an unusual nature which, in the judgment of management after consultation with its legal or tax counsel, may be of interest to shareholders or others.

Taxes collected from customers and remitted to governmental authorities

Refundable taxes (excise and value-added tax ("VAT")) are deducted from revenues. Other taxes and duties are not deducted from revenues and are recognized as expenses in Taxes other than income tax in the consolidated statement of profit or loss.

VAT and excise receivable and payable are recognized as Prepayments and other current assets and Other tax liabilities in the consolidated balance sheet, respectively.

3. Significant accounting policies (continued)

Functional and presentation currency

The consolidated financial statements are presented in Russian rubles, which is the functional currency of Rosneft Oil Company and all of its subsidiaries operating in the Russian Federation. The functional currency of the foreign subsidiaries is generally the U.S. dollar.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of these transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year-end exchange rates are recognized in the profit or loss for the period.

Foreign exchange gains and losses resulting from the translation of monetary assets and liabilities designated as foreign currency cash flow hedging instruments are recognized within other comprehensive income and reclassified to profit or loss in the period when the hedged item affects profit or loss.

Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined.

The Company's subsidiaries

The results and financial position of all of the Company's subsidiaries, joint ventures and associates that have a functional currency which is different from the presentation currency are translated into the presentation currency as follows:

· assets and liabilities for each balance sheet presented are translated at the closing rate at that reporting date;

· income and expenses for each statement of profit or loss and each statement of other comprehensive income are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the dates of the transactions); and

· all resulting exchange differences are recognized as a separate component of other comprehensive income.

Prepayment on oil and petroleum products supply agreements

In the course of business the Company enters into long-term oil supply contracts. The contract terms may require the buyer to make a prepayment.

The Company considers long-term oil supply contracts to be regular-way sale contracts entered into and continued to be held for the purpose of the receipt or delivery of non-financial items in accordance with the Company's expected purchase, sale or usage requirements. Regular-way sale contracts are exempted from the scope of IAS 32 Financial Instruments: Presentation and IAS 39 Financial Instruments: Recognition and Measurement.

3. Significant accounting policies (continued)

Prepayment on oil and petroleum products supply agreements (continued)

Conditions for meeting the definition of a regular-way sale are not met if either of the following applies:

· the ability to settle net in cash or another financial instrument, or by exchanging financial instruments, is not explicit in the terms of the contract, but the Company has a practice of settling similar contracts net in cash or via another financial instrument or by exchanging financial instruments (whether with the counterparty, by entering into offsetting contracts or by selling the contract before its exercise or lapse);

· for similar contracts, the Company has a practice of taking delivery of the underlying goods and selling them within a short period after delivery for the purpose of generating a profit from short-term fluctuations in price or from a dealer's margin.

Prepayments for the delivery of goods or respective deferred revenue are accounted for as non-financial liabilities because the outflow of economic benefits associated with them is the delivery of goods and services rather than a contractual obligation to pay cash or another financial asset.

Changes in accounting policies and disclosures

The accounting policies adopted are consistent with those of the previous financial year except for the adoption of new standards and interpretations effective as of January 1, 2017. 

The following amendments were applied for the first time in 2017:

· Disclosure Initiative - amendments to IAS 7 Statement of Cash Flows. The amendments require companies to provide a reconciliation of financing cash flows in the statement of cash flows to the opening and closing balances of liabilities arising from financing activities (except for equity balances) in the statement of financial position. The above mentioned reconciliation is presented in Note 31 "Loans and borrowings and other financial liabilities".

· Deferred Tax Assets for Unrealised Losses - amendments to IAS 12 Income Taxes. These amendments clarify how to account for deferred tax assets related to debt instruments measured at fair value.

Application of these amendments had no significant impact on the Company's financial position or results of operations.

Certain prior period balances have been reclassified to conform to the current year presentation.

4. Significant accounting judgments, estimates and assumptions

The preparation of consolidated financial statements requires management to make a number of accounting estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities. The actual results, however, could differ from those estimates.

4. Significant accounting judgments, estimates and assumptions (continued)

The most significant accounting estimates and assumptions used by the Company's management in preparing the consolidated financial statements include:

· estimation of oil and gas reserves;

· estimation of rights to, recoverability and useful lives of non-current assets;

· impairment of goodwill (Note 25 "Intangible assets and goodwill");

· allowances for doubtful accounts receivable and obsolete and slow-moving inventories (Note 21 "Accounts receivable" and Note 22 "Inventories");

· assessment of asset retirement (decommissioning) obligations (Note 3 "Significant accounting policies", section: "Asset retirement (decommissioning) obligations", and Note 32 "Provisions");

· assessment of legal and tax contingencies, recognition and disclosure of contingent liabilities (Note 40 "Contingencies");

· assessment of deferred income tax assets and liabilities (Note 3 "Significant accounting policies", section: "Income tax", and Note 16 "Income tax");

· assessment of environmental remediation obligations (Note 32 "Provisions" and Note 40 "Contingencies");

· fair value measurements (Note 37 "Fair value of financial instruments");

· assessment of the Company's ability to renew operating leases and to enter into new lease agreements;

· purchase price allocation to the identifiable assets acquired and the liabilities assumed (Note 7 "Acquisition of subsidiaries and shares in joint operations").

Significant estimates and assumptions affecting the reported amounts are those used in determining the economic recoverability of reserves.

Such estimates and assumptions may change over time when new information becomes available, e.g.:

· more detailed information on reserves was obtained (either as a result of more detailed engineering calculations or additional exploration drilling activities);

· supplemental activities to enhance oil recovery were conducted;

· changes were made in economic estimates and assumptions (e.g. a change in pricing factors).

5. New and amended standards and interpretations issued but not yet effective

In May 2014, the IASB issued IFRS 15 Revenue from Contracts with Customers. IFRS 15 establishes a single framework for revenue recognition and contains requirements for related disclosures. The new standard replaces IAS 18 Revenue, IAS 11 Construction Contracts, and the related interpretations on Revenue recognition. The standard is effective for annual periods beginning on or after January 1, 2018. In April 2016, the IASB issued amendments to IFRS 15, which have the same effective date as the new standard: January 1, 2018. As a result of the analysis performed by the Company, the conclusion was made that there will be no significant impact of the standard on the consolidated financial statements.

5. New and amended standards and interpretations issued but not yet effective (continued)

In July 2014, the IASB issued the final version of IFRS 9 Financial Instruments. The final version of IFRS 9 replaces IAS 39 Financial Instruments: Recognition and Measurement, and all previous versions of IFRS 9. IFRS 9 brings together the requirements for the classification and measurement, impairment and hedge accounting of financial instruments. In respect of impairment, IFRS 9 replaces the "incurred loss" model used in IAS 39 with a new "expected credit loss" model that will require a more timely recognition of expected credit losses. The standard is effective for annual periods beginning on or after January 1, 2018. In October 2017, the IASB issued amendments to IFRS 9 effective on January 1, 2019.

The Company is currently assessing the impact of the standard on the opening balance of retained earnings as of January 1, 2018 as a result of the shift from the "incurred loss" impairment model to "expected credit loss" model, аs well as the change in classification for certain significant financial assets of the Company - from the "amortized cost" category to the "fair value through profit or loss" category.

In September 2014, the IASB issued amendments to IFRS 10 Consolidated Financial Statements and IAS 28 Investments in Associates and Joint Ventures entitled Sale or Contribution of Assets between an Investor and its Associate or Joint Venture. These narrow scope amendments clarify that a full gain or loss is recognized when a transaction involves a business (whether it is housed in a subsidiary or not), and a partial gain or loss is recognized when a transaction involves assets that do not constitute a business. The IASB has postponed the date by when the entities must change these aspects of accounting for transactions between investors and equity accounted investees. Application of the amendments, initially planned for annual periods beginning on or after January 1, 2016, has been deferred. The Company does not expect the amendments to have a material impact on the consolidated financial statements, as their requirements are already incorporated in the accounting policy of the Company.

In January 2016, the IASB issued IFRS 16 Leases. IFRS 16 eliminates the classification of leases as either operating leases or finance leases and establishes a single lessee accounting model. The most significant effect of the new requirements for the lessee will be an increase in lease assets and financial liabilities. The new standard replaces the previous leases standard, IAS 17 Leases, and the related interpretations. The standard is effective for annual periods beginning on or after January 1, 2019, with earlier application permitted for companies that also apply IFRS 15 Revenue from Contracts with Customers. The Company is currently assessing the impact of the standard on the consolidated financial statements.

In June 2016, the IASB issued amendments to IFRS 2 Share-based Payment entitled Classification and Measurement of Share-based Payment Transactions. The amendments provide requirements for the accounting for the effects of vesting and non-vesting conditions on the measurement of cash-settled share-based payments; share-based payment transactions with a net settlement feature for withholding tax obligations; a modification to the terms and conditions of a share-based payment that changes the classification of the transaction from cash-settled to equity-settled. The amendments are effective for annual periods beginning on or after January 1, 2018, with earlier application permitted. The Company does not expect the amendments to have a material impact on the consolidated financial statements.

In September 2016, the IASB issued amendments to IFRS 4 Insurance Contracts entitled Applying IFRS 9 Financial Instruments with IFRS 4 Insurance Contracts. The amendments address concerns arising from implementing the new financial instruments Standard, IFRS 9, before implementing the replacement Standard that the Board is developing for IFRS 4. The amendments introduce two approaches, which should reconcile the timing of the application of the two new standards. Under the first approach, the amendments become effective on the date of first-time adoption of IFRS 9; under the second, the amendments become effective for annual periods beginning on or after January 1, 2018. The Company does not expect the amendments to have a material impact on the consolidated financial statements.

5. New and amended standards and interpretations issued but not yet effective (continued)

In December 2016, the IASB issued IFRIC 22 Interpretation entitled Foreign Currency Transactions and Advance Consideration. The IFRIC addresses how to determine the date of the transaction for the purpose of determining the exchange rate to use on initial recognition of the related asset, expense or income (or part of it) on the derecognition of a non-monetary asset or non-monetary liability arising from the payment or receipt of advance consideration in a foreign currency. IFRIC 22 is effective for annual periods beginning on or after January 1, 2018, with earlier application permitted. The Company does not expect the amendments to have a material impact on the consolidated financial statements as their requirements are already incorporated in the accounting policy of the Company.

In December 2016, the IASB issued amendments to IAS 40 Investment Property entitled Transfers of Investment Property. The amendments clarify the requirements for transfers to, or from, investment property. The amendments are effective for annual periods beginning on or after January 1, 2018, with earlier application permitted. The Company does not expect the amendments to have a material impact on the consolidated financial statements.

In May 2017, the IASB issued IFRS 17 Insurance Contracts. IFRS 17 establishes a single framework for the accounting for insurance contracts and contains requirements for related disclosures. The new standard replaces IFRS 4 Insurance Contracts. The standard is effective for annual periods beginning on or after January 1, 2021. The Company does not expect the standard to have a material impact on the consolidated financial statements.

In June 2017, the IASB issued IFRIC 23 Interpretation entitled Uncertainty over Income Tax Treatments. The IFRIC clarifies that for the purposes of calculating current and deferred tax, companies should use a tax treatment of uncertainties, which will probably to be accepted by the tax authorities. IFRIC 23 is effective for annual periods beginning on or after January 1, 2019. The Company does not expect the amendments to have a material impact on the consolidated financial statements.

In October 2017, the IASB issued amendments to IAS 28 Investments in Associates and Joint Ventures. These amendments clarify that the companies should apply IFRS 9 Financial Instruments, including impairment requirements, for the long-term investments in associates and joint ventures, which are accounted for otherwise than using the equity method, including long-term loans given to associates and joint ventures. The amendments are effective for annual periods beginning on or after January 1, 2019, with earlier application permitted. The impact of the amendments was assessed within the assessment of the impact of IFRS 9 Financial Instruments (see above).

6. Capital and financial risk management

Capital management

The Company's capital management objectives are to ensure its ability to continue as a going concern and to optimize the cost of capital in order to enhance value to shareholders. Total capital employed and financial liabilities less liquid financial assets are non-IFRS measure.

The Company's management performs a regular assessment of the financial liabilities less liquid financial assets to capital employed ratio to ensure it meets the Company's requirements to fulfil the Company's commitments and to retain strong financial stability.

6. Capital and financial risk management (continued)

Capital management (continued)

The Company's employed capital is calculated as the sum of equity attributable to equity holders of Rosneft: share capital, reserves, retained earnings and non-controlling interests; financial liabilities, which include long and short-term loans and borrowings, other financial liabilities, as reported in the consolidated balance sheet, less liquid financial assets, including cash and cash equivalents, other short-term financial assets and certain long-term deposits. The Company's financial liabilities less liquid financial assets to capital employed ratio was as follows:

Financial risk management

In the normal course of business the Company is exposed to the following financial risks: market risk (including foreign currency risk, interest rate risk and commodity price risk), credit risk and liquidity risk. The Company has introduced a risk management system and developed a number of procedures to measure, assess and monitor risks and select the relevant risk management techniques.

The Company has developed, documented and approved the relevant policies pertaining to market, credit and liquidity risks and the use of derivative financial instruments.

Foreign currency risk

The Company undertakes transactions denominated in foreign currencies and is exposed to foreign exchange risk arising from various currency exposures, primarily with respect to the U.S. dollar and euro. Foreign exchange risk arises from assets, liabilities, commercial transactions and financing denominated in foreign currencies.

The carrying values of monetary assets and liabilities denominated in foreign currencies are presented in the table below:

The Company seeks to identify and manage foreign exchange rate risk in a comprehensive manner, including an integrated analysis of natural economic hedges, in order to benefit from the correlation between income and expenses. The Company chooses the currency in which to hold cash, such as the Russian ruble, U.S. dollar or other currency for short-term risk management purposes.

The long-term risk management strategy of the Company may involve the use of derivative or non-derivative financial instruments in order to minimize foreign exchange rate risk exposure.

6. Capital and financial risk management (continued)

Cash flow hedging of the Company's future exports

The Company designated certain U.S. dollar denominated borrowings as a hedge of the expected highly probable U.S. dollar denominated export revenue stream in accordance with IAS 39 Financial Instruments: Recognition and Measurement.

A portion of future monthly export revenues expected to be received in U.S. dollars was designated as a hedged item. The nominal amounts of the hedged item and the hedging instruments were equal. To the extent that a change in the foreign currency rate impacts the fair value of the hedging instrument, the effects are recognized in other comprehensive income or loss and then reclassified to profit or loss in the same period in which the hedged item affects the profit or loss.

The Company's foreign currency risk management strategy is to hedge future export revenue in the amount of the net monetary position in U.S. dollars. The Company aligns the hedged nominal amount to the net monetary position in U.S. dollars on a periodical basis.

Changes in the nominal hedging amount during 2017 are presented in the table below:

The impact of foreign exchange cash flow hedges recognized in other comprehensive income is set out below:

6. Capital and financial risk management (continued)

Cash flow hedging of the Company's future exports (continued)

The schedule of the expected reclassification of the accumulated foreign exchange loss from other comprehensive income to profit or loss, as of December 31, 2017, is presented below:

The expected reclassification is calculated using the Central Bank of Russia ("CBR") exchange rate as of December 31, 2017 and may be different using actual exchange rates in the future.

Analysis of sensitivity of financial instruments to foreign exchange risk

The level of currency risk is assessed on a monthly basis using sensitivity analysis and is maintained within the limits adopted in line with the Company's policy. The table below summarizes the impact on the Company's income before income tax and equity of the depreciation/(appreciation) of the Russian ruble against the U.S. dollar and euro.

Interest rate risk

Loans and borrowings raised at variable interest rates expose the Company to interest rate risk arising from the possible movement of variable elements of the overall interest rate.

As of December 31, 2017, the Company's variable rate liabilities totaled RUB 1,543 billion (net of interest payable). The Company analyzes its interest rate exposure, including by performing scenario analysis to measure the impact of an interest rate shift on annual income before income tax.

The table below summarizes the impact of a potential increase or decrease in interest rates on the Company's profit before tax, as applied to the variable element of interest rates on loans and borrowings. The increase/decrease is based on management estimates of potential interest rate movements.

The sensitivity analysis is limited to variable rate loans and borrowings and is conducted with all other variables held constant. The analysis is prepared with the assumption that the amount of variable rate liability outstanding at the balance sheet date was outstanding for the whole year. The interest rate on variable rate loans and borrowings will effectively change throughout the year in response to fluctuations in market interest rates.

6. Capital and financial risk management (continued)

Interest rate risk (continued)

The impact measured through the sensitivity analysis does not take into account other potential changes in economic conditions that may accompany the relevant changes in market interest rates.

Credit risk

The Company controls its own exposure to credit risk. All external customers and their financial guarantors, other than related parties, undergo a creditworthiness check (including sellers of goods and services who act on a prepayment basis). The Company performs an ongoing assessment and monitoring of the financial position and the risk of default. In the event of a default by the parties on their respective obligations under the financial guarantee contracts, the Company's exposure to credit risk will be limited to the corresponding contract amounts. As of December 31, 2017, management assessed such risk as remote.

In addition, as part of its cash management and credit risk function, the Company regularly evaluates the creditworthiness of financial and banking institutions where it deposits cash and performs trade finance operations. The Company primarily has banking relationships with the Russian subsidiaries of large international banking institutions and certain large Russian banks. The Company's exposure to credit risk is limited to the carrying value of financial assets recognized on the consolidated balance sheet.

Liquidity risk

The Company has mature liquidity risk management processes covering short-term, mid-term and long-term funding. Liquidity risk is controlled through maintaining sufficient reserves and the adequate amount of committed credit facilities and loan funds. Management regularly monitors projected and actual cash flow information, analyzes the repayment schedules of the existing financial assets and liabilities, including upcoming un-accrued interest payments, and performs annual detailed budgeting procedures.

The contractual maturities of the Company's financial liabilities are presented below:

Liquidity risk (continued)

As of December 31, 2017, the Company's current liabilities exceeded its currents assets. Management believes that the Group's current cash on hand, expected cash flows from operations and available standby credit facilities from financial institutions will be sufficient to meet the Company's working capital requirements and repay its short-term debts and obligations when they become due. In 2017, the Company was attracting other short-term borrowings under repurchasing agreement operations, using the favorable market conditions. As a result, the amount of short-term liabilities increased while an adequate level of liquidity risk was maintained.
