PJSC Deloitte & Touche USC 48, 50A, Zhylyanska St. Kyiv 01033 Ukraine Tel.: +38 (044) 490 9000 Fax: +38 (044) 490 9001 www.deloitte.ua PUBLIC JOINT STOCK COMPANY NATIONAL JOINT STOCK COMPANY INDEPENDENT AUDITOR S REPORT To the shareholder of Public Joint Stock Company National Joint Stock Company Naftogaz of Ukraine : We have audited the accompanying consolidated statement of financial position as at 2013 of Public Joint Stock Company National Joint Stock Company Naftogaz of Ukraine (the Company ) and its subsidiaries (collectively, the Group ), and we were engaged to audit the consolidated statement of financial position as at, and the consolidated statements of profit or loss, the consolidated statements of comprehensive income, consolidated statements of changes in equity and the consolidated statements of cash flows of the Group for the years ended 2013 and, and a summary of significant accounting policies and other explanatory information. Management s Responsibility for the Consolidated Financial Statements Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with International Financial Reporting Standards ( IFRS ), 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. Auditor s Responsibility Our responsibility is to express an opinion on the consolidated statement of financial position as at 2013 based on our audit. Because of the matters described in the Basis for Qualified Opinion and Disclaimer of Opinion paragraphs below, we were not able to obtain sufficient and appropriate audit evidence to provide a basis for an audit opinion on the Group s consolidated financial position as at, and the consolidated results of its operations and cash flows of the Group for the years ended 2013 and. We conducted our audit of the consolidated statement of financial position as at 2013 in accordance with International Standards on Auditing. Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated statement of financial position is free from material misstatement. An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated statement of financial position. The procedures selected depend on the auditor s judgment, including the assessment of the risks of material misstatement of the consolidated statement of financial position, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity s preparation and fair presentation of the consolidated statement of financial position 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 entity s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated statement of financial position. Deloitte refers to one or more of Deloitte Touche Tohmatsu Limited, a UK private company limited by guarantee, and its network of member firms, each of which is a legally separate and independent entity.

We believe that the audit evidence we have obtained in our audit is sufficient and appropriate to provide a basis for our qualified audit opinion on the Group s consolidated financial position as at 2013. Basis for Qualified Opinion on the Consolidated Financial Position of the Group as at 2013 and Disclaimer of Opinion on the Consolidated Financial Position of the Group as at, and on the Consolidated Results of its Operations and Cash Flows for the Years Ended 2013 and 1) As discussed in Note 25 to the consolidated financial statements, the Group has adopted the revaluation model for measurement of property, plant and equipment, which requires revaluations to be carried out with sufficient regularity so that the carrying amount of property, plant and equipment as at the reporting date does not differ materially from its fair value. The Group s property, plant and equipment were last independently revalued on 2009. Significant economic developments since that date, including changes in natural gas transportation tariffs and costs, selling prices of the Group s own extracted natural gas, and construction costs provide indications of a possible material change in the fair values of property, plant and equipment. In the absence of a current independent revaluation, we were unable to obtain sufficient and appropriate audit evidence about the impact of these matters on the Group s property, plant and equipment with carrying amounts of UAH 89,526 million and UAH 93,460 million as at 2013 and, respectively, and the related impact on revaluation reserve and deferred tax liabilities as at those dates, the depreciation, depletion and amortization expense and deferred tax expense for the years then ended. As a result of these matters we were unable to determine whether any adjustments to these amounts were necessary. 2) As discussed in Note 25 to the consolidated financial statements, oil and gas assets are depleted using a unit-of-production method in proportion to proved developed hydrocarbon reserves. The Group s hydrocarbon reserves were last independently revalued on 2010. Management has applied judgment in making estimates of hydrocarbon reserves as at 2013 and. In the absence of a current independent revaluation, we were unable to obtain sufficient and appropriate audit evidence about the impact of this matter on the Group s oil and gas assets with carrying amounts of UAH 20,416 million and UAH 20,524 million as at 2013 and, respectively, and the related impact on deferred tax liabilities as at those dates, the depreciation, depletion and amortization expense and deferred tax expense for the years then ended. As a result of these matters we were unable to determine whether any adjustments to these amounts were necessary. 3) As discussed in Note 24 to the consolidated financial statements, in March 2014 the Group lost control over one of its subsidiaries, JSC Chornomornaftogaz, the majority of whose assets are located in the territory of Autonomous republic of Crimea. As at 2013 and the total assets of this subsidiary were UAH 15,744 million and UAH 16,136 million, total liabilities were UAH 14,089 million and UAH 14,322 million, respectively, total revenues were UAH 525 million and UAH 550 million, and total expenses were UAH 1,399 million and UAH 1,219 million for the years then ended, respectively. We were not provided with access to the financial information of this subsidiary. Additionally, we were not able to get access to other assets of the Group located in the territory of Autonomous republic of Crimea amounting to UAH 2,898 million and UAH 2,643 million at 2013 and, respectively. As a result of these matters we were unable to determine whether any adjustments to these amounts were necessary. 4) We were appointed as auditors of the Group after 2013 and thus, did not observe the counting of the physical inventories as at 2013 and. Other than with regard to natural gas, we were unable to satisfy ourselves by alternative means concerning inventory quantities held at 2013 and in the amount of UAH 607 million and UAH 6,115 million, and the related impact of this matter on the consolidated results of operations and opening balance of accumulated deficit for the years ended 2013 and, respectively. As a result of this matter, we were unable to determine whether any adjustments to these amounts were necessary. 3

5) As presented in Note 7 to the consolidated financial statements, the Group has investments in associates and joint ventures which are accounted for using the equity method of accounting. The carrying amounts of investments in joint ventures were UAH 777 million and UAH 606 million as at 2013 and, respectively, and the Group s related share of after tax results of joint ventures in the amount of UAH 329 million and UAH 351 million is included in the net loss for the years then ended, respectively. We were unable to obtain sufficient and appropriate audit evidence about: the expenses incurred by associates and included in the after tax results of associates for the year ended 2013 with the Group share of such expenses amounting to UAH 925 million; and the carrying amount of the Group s investment into joint ventures as at 2013 and, and the Group s share of their after tax results for the years then ended as we were not provided access to the financial information of the joint ventures. As a result of these matters, we were unable to determine whether any adjustments to these amounts were necessary. 6) As discussed in Notes 17, 18 and 25, during the years ended 2013 and, respectively, the Group has incurred expenditures for: The purchase of services and inventories amounting to UAH 1,082 million and UAH 1,983 million, which are included into cost of sales for which the source documents were sequestered and are under investigation by the office of State Prosecutor of Ukraine; Research, development and exploration amounting to UAH 455 million and UAH 2,169 million, which are included into other operating expenses, and the Group made prepayments for above mentioned services of UAH 37 million and UAH 488 million recorded in the consolidated statements of financial position as at 2013 and, respectively, for which the source documents were sequestered and are under investigation by the office of State Prosecutor of Ukraine; The purchase of property, plant and equipment of UAH 4,335 million and UAH 11,097 million; and The purchase of services and inventories included into cost of sales and other operating expenses of UAH 2,927 million and UAH 3,366 million. As stated in Notes indicated above the substance of these expenditures may not reflect the actual legal form of the source documents. We were unable to obtain sufficient and appropriate audit evidence to satisfy ourselves as to the amounts and nature of the above expenditures and their classification in the consolidated financial statements for the years ended 2013 and. As a result, we were unable to determine whether any adjustments to these amounts were necessary. 7) We were unable to obtain sufficient and appropriate audit evidence regarding completeness of revenue recorded in the accompanying consolidated financial statements of the Group on sales of petroleum products to certain customers in the amounts of UAH 2,853 million and UAH 1,734 million for the years ended 2013 and, respectively. As a result of these matters, we were unable to determine whether any adjustments to these amounts were necessary. Disclaimer of Opinion on the Consolidated Financial Position of the Group as at, and the Consolidated Results of its Operations and Cash Flows for the years ended 2013 and Because of the significance of the matters described in the paragraphs 1-7 above, we have not been able to obtain sufficient and appropriate audit evidence to provide a basis for an audit opinion on the consolidated financial position of the Group as at, and the consolidated results of its operations and cash flows for the years ended 2013 and. Accordingly, we do not express an opinion on the consolidated financial position of the Group as at, and the consolidated results of its operations and cash flows for the years ended 2013 and. 4

Qualified Opinion on the Consolidated Financial Position of the Group as at 2013 In our opinion, except for the possible effects of the matters described in the paragraphs 1-6 above, the consolidated statement of financial position present fairly, in all material respects, the consolidated financial position of the Group as at 2013 in accordance with International Financial Reporting Standards. Emphasis of Matter The accompanying consolidated financial statements have been prepared assuming that the Group will continue as a going concern. As discussed in Note 2 and Note 21 to the consolidated financial statements, the Group's negative working capital as at 2013 and amounted to UAH 53,893 million and UAH 33,208 million, respectively, and for the years then ended the Group incurred net losses in the amounts of UAH 17,957 million and UAH 31,466 million, respectively, and there is uncertainty as to the outcome of significant ongoing litigations for the Group. These conditions raise substantial doubt about the Group s ability to continue as a going concern. Management's plans concerning these matters are discussed in Note 2 to the consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Our opinion is not qualified in respect of this matter. We also draw your attention to Note 24 to the consolidated financial statements, which describes significant subsequent events affecting the Group s operations in the territory of Autonomous republic of Crimea and the economical and political uncertainty in Ukraine. The continuing impact of these matters on the business environment in Ukraine and their final resolution are unpredictable and may adversely affect the Ukrainian economy and the operations of the Group. Our opinion is not qualified in respect of this matter. We further draw your attention to Note 3 to the consolidated financial statements, which describes that the accompanying consolidated statement of financial position as at 1 January has been restated. Our opinion is not qualified in respect of this matter. Other Matter The consolidated financial statements of the Group for the year ended 2011 before restatement adjustments as described in Note 3 to the consolidated financial statements, were audited by another auditor whose opinion on those consolidated financial statements dated 12 December expressed a qualified opinion on the following matters: Inability to observe stock-taking as at 2011; Non-recognition of changes in the Group s share of net assets in associate for the years 2011 and 2010, except for dividends accrued; Accounting of investments in some subsidiaries and associates at cost, rather than their consolidation and application of equity method, respectively; Absence of an independent valuation of hydrocarbon reserves of the Group as at 2011 for determination of depreciation of oil and gas assets. 27 February 2015 5

2. OPERATING ENVIRONMENT Emerging markets such as Ukraine are subject to different risks than more developed markets, including economic, political and social, and legal and legislative risks. Laws and regulations affecting businesses in Ukraine continue to change rapidly, tax and regulatory frameworks are subject to varying interpretations. The future economic direction of Ukraine is heavily influenced by the fiscal and monetary policies adopted by the government, together with developments in the legal, regulatory, and political environment. In and 2013, the economy of Ukraine displayed characteristics of being in recession. Since the end of 2013, Ukraine has been in a political and economic turmoil. As a result of a number of protests, the President was dismissed and new Parliament majority coalition was formed. In February 2014 the new Prime Minister and the new Government were appointed. Following the changes in the Government, the Company s management had been changed in April-June 2014, and new Board was formed. The Group is a guaranteed supplier of natural gas in Ukraine, and its ability to adjust prices to the end customers, together with increased prices for the imported gas, is limited, since such prices are regulated at each stage from exploration to end customers by the National Commission for Energy and Public Utilities State Regulation ( NERC, before 27 August 2014 National Committee on Energy Regulation, NCER). The domestic natural gas supply in Ukraine satisfies only one third of the total demand. Consequently, significant level of gas import is required to meet needs of domestic consumption. During -2013 there were no significant fluctuations in purchase and sales prices on the gas market in Ukraine. During and 2013, the Company imported natural gas mainly from JSC Gazprom, the Russian Federation ( Gazprom ), in accordance with the agreement between the Company and Gazprom signed in January 2009 ( Agreement on gas purchase ). The Agreement on gas purchase covers period of supplies for 2009 to 2019 and prescribes formulas for gas prices. The Government of Ukraine controls the Group s operations through its ownership rights in the Company. Such an impact may result in social and economic initiatives that may lead to an adverse effect on the Group s operations. Management is unable to predict a potential impact of such initiatives on the Group s consolidated financial position and its performance. State regulation of the natural gas market in Ukraine State regulation of the natural gas market in Ukraine is performed by the Cabinet of Ministers of Ukraine and by the NERC. State regulation covers both technical and financial aspect of the market functioning. Technical measures relate to effective use of natural gas resources, ensuring secure technical exploitation of the gas transportation system, maintaining correct and safe supply, distribution and consumption of the natural gas. Financial measures mainly relate to the tariff and price setting and to the keeping the correct financial means allocation between the market participants. The Cabinet of Ministers of Ukraine must approve annual forecast of natural gas supply and its distribution. 13

2. OPERATING ENVIRONMENT (Continued) NERC performs regulation of tariffs and prices set at the each stage from production to sales of natural gas, by setting appropriate prices and tariffs and approving procedures of calculating those prices and tariffs. Accordingly, NERC approves the maximum sales price of natural gas for entities financed from the State and local budgets, the maximum sales price of natural gas for industrial customers and other entities (including heat generating entities, producing heat for households), retail sales prices of natural gas for households, tariffs for transportation services via transmission and distribution pipelines within Ukraine, tariffs for distribution and supply of natural gas under the regulated tariffs, tariffs for storage and pumping services. NERC approves procedures of setting sales prices for natural gas for natural gas production entities, sales prices for natural gas for households, and setting transportation, distribution and storage tariffs for natural gas. Additionally, NERC is responsible for protection of the customer rights in the area of tariff setting, security of supplies and quality of services. The following tariffs and prices were set as at 2013 and : 2013 Retail prices for natural gas for households depend on the volume of consumption and availability of gas meters (UAH per cubic meter). Starting from 1 May 2014 increased retail prices for households were set at the level from UAH 1.18 to UAH 4.01 per cubic meter of gas, including VAT, other sales taxes, tariffs for transportation and distribution of natural gas under the regulated tariffs. Maximum purchase price of natural gas for industrial customers, net of VAT, other sales taxes, tariffs for transportation and distribution of natural gas under the regulated tariffs. Starting from 1 April 2014, the maximum purchase price of natural gas for the industrial customers and entities financed from the State and local budgets was increased up to UAH 4,020 per thousand of cubic meters, net of VAT, other sales taxes, tariffs for transportation and distribution of natural gas under the regulated tariffs. From UAH 0.7 to UAH 2.95 per cubic meter UAH 3,459 per thousand of cubic meters From UAH 0.7 to UAH 2.95 per cubic meter UAH 3,509 per thousand of cubic meters Total tariff for storage (storage and pumping services), net of VAT, UAH per thousand of cubic meters per one season of storage. Total tariff for transportation services via transmission and distribution pipelines within Ukraine, net of VAT, UAH per thousand cubic meters. 33 33 295.6 305.6 According to the Law of Ukraine On the natural gas market functioning, the whole volume of natural gas produced in Ukraine by the entities owned 50% and more by the State, should be sold to the households via the Company at regulated prices. If the demand of the households exceeds the production volumes, it is satisfied from the other sources of supply, including imports. Natural gas volumes consumed by households are reported via the gas meters. If no meters are available the sales volume is reported at the average normal consumption rates set by the respective regulations. 14

2. OPERATING ENVIRONMENT (Continued) All customers, except for heat generating companies, settle their debts on natural gas consumed via special purpose bank accounts. The list of banks creating such accounts is approved by the Cabinet of Ministers of Ukraine. According to current procedure, guaranteed natural gas suppliers and distributors of natural gas for all groups of customers, should open special purpose bank accounts to receive payments for natural gas consumed. Amounts accumulated on the special purpose bank accounts are allocated to current accounts of the transmission pipelines operator, distribution pipelines operators, and guaranteed suppliers according to ratios calculated by the guaranteed suppliers and approved by NERC. Balances on the special purpose accounts could not be arrested or blocked. Heat generating companies also open special purpose banks accounts for the settlement of debts for heat supplied. Cash received by heat generating entities on their special purpose bank accounts then allocated, among others, to current bank accounts of the guaranteed suppliers of natural gas according to ratios approved by NERC monthly. The special purpose bank accounts of heat generating companies also could not be blocked or arrested. Compensation of price difference between sales tariffs and price of imported gas and other types of financial support by the State As described above, the Company imports significant amount of natural gas to meet the domestic demand. The price of imported gas is significantly higher than the sales tariff set by NERC and invoiced by the Company to certain groups of domestic customers, namely households and heat generating companies. The negative difference is compensated by the State to the Company, as prescribed by the Resolution of the Cabinet of Ministers of Ukraine No.605 dated 29 April 2006 ( compensation of price difference ). Historically, such compensation of price difference covered 70-75% of the price of imported gas. The timing and legal form of such compensation is not set in the Ukrainian legislation. The actual amount of price difference to be compensated in respective period is approved by the State as an expense in the Law on the State Budget for respective period. The Company calculates the full amount of price difference accumulated during each year and submits it to the Government. However, during the reporting periods and up to the date of these consolidated financial statements there were no documents stating the amount of compensation of price difference due to the Company. The Company recognises income from the compensation actually received on a cash basis. In the Company received UAH 3,900 million of such compensation, recognised as an income. The following information summarises the information on the price difference estimated by the Company for compensation, and financial support from the Government to the Company in -2013 (unaudited): In millions of Ukrainian hryvnias 2013 Estimated price difference for the period 11,723 11,701 Financial support from the State: Compensation of price difference received in cash during the period - 3,900 State treasury bonds received from the Government in exchange for the new share issue during the period 8,000 6,000 Total financial support received from the State 8,000 9,900 15

2. OPERATING ENVIRONMENT (Continued) Estimated price difference is calculated as a difference in fair import prices and NERC sales tariffs of gas sold to heat generating companies for selling to households. As described in Note 21, the Company has requested the Arbitral Tribunal to render an award in relation to the level of the natural gas import prices for 2010-2014. The price actually paid to Gazprom, is higher than the fair price as claimed by the Company. Had the Company calculated the price difference at amounts actually paid to Gazprom, the estimated price difference for 2013 and would be UAH 20,753 million and UAH 18,707 million, respectively. Together with the compensation of price difference, the Company receives financial support from the State in the form of the State treasury bonds received in exchange of new share issue of the Company (Note 13). The funds received are aimed to cover the current liquidity gap of the Company. It could be claimed that the amount of State treasury bonds received by the Company in exchange of the new share issue partially covers compensation of the price difference, however, there is no legal support or documents confirming this statement, and there is no reconciliation act or similar document signed between the Company and the Government of Ukraine, stating the outstanding amount of compensation of the price difference. As a result, the Company has significant accumulated losses and overstated share capital. Going Concern The Group s negative working capital as at 2013 and amounted to UAH 53,893 million and UAH 33,208 million, respectively, for the years then ended the Group incurred net losses in the amounts of UAH 17,957 million and UAH 31,466 million, respectively. Management of the Group believes that it is appropriate to prepare these consolidated financial statements on a going concern basis as the Group and the Government of Ukraine has undertaken several initiatives aimed to improve the financial performance and liquidity of the Group, including, but not limited by the following: Since the beginning of 2014, the Government of Ukraine has undertaken a number of measures aiming to gradually bring the retail gas and heating prices to cost recovery levels based on international gas prices. The Government announced its plans to change energy subsidy system by increasing the direct subsidies to final consumers (mainly households and heating production companies) and reducing the extent of the price regulation. Successful implementation of these plans would significantly reduce the Company s financial deficit in 2015-2016 and completely eliminate it by 2017. The Government of Ukraine and the Group have been undertaking steps to diversify the sources of gas supplies primarily from European companies through Slovakia, Poland and Hungary. In addition, the Group expects that market prices for gas will go down following a substantial reduction of oil prices that occurred in the end of 2014 and onwards. The Government approved the use of funds allocated in the State budget of Ukraine for to compensate Naftogaz of Ukraine for the difference between the purchase price of imported natural gas and its sales price to entities generating and selling heat to the households. According to the approved procedures, the Company received compensation of UAH 3.9 billion in cash in. In, 2013 and 2014 the Government of Ukraine has provided to the Company State treasury bonds amounting to UAH 6 billion, UAH 8 billion and UAH 96.6 billion, respectively, in exchange for the new share issue. Subsequently, the Company registered share capital increase of UAH 6 billion in 2014, and received a temporary share registration certificates for UAH 104.6 billion. The bonds received were sold for cash. Furthermore, the state budget of Ukraine for 2015 includes additional issue of UAH 27.9 billion of State treasury bonds in exchange for the new share issue by the Company. 16

2. OPERATING ENVIRONMENT (Continued) The State budget for included UAH 10.4 billion of heat tariff compensation to the heat generating companies, which then were used to settle debts for natural gas supplied by the Group. Management believes that the combination of above mentioned measures and other measures from the Government of Ukraine will enable the Group to continue as a going concern. These consolidated financial statements do not include any adjustments relating to recoverability and classification of the recorded assets amounts, or to amounts and classification of liabilities that may be necessary if the Group is unable to continue as a going concern. 3. RESTATEMENT OF COMPARATIVE INFORMATION The Group has issued the consolidated financial statements as at and for the year ended 2011 on 12 December. Subsequently to that date, the Group identified errors of prior reporting periods, which had significant effect on the statement of financial position as at 1 January. These errors were corrected retrospectively in these consolidated financial statements as at and for the years ended 2013 and.

3. RESTATEMENT OF COMPARATIVE INFORMATION (Continued) In millions of Ukrainian hryvnias Note 1 January, as reported previously Effect of the restatement and reclassification 1 January, as restated Deferred tax liabilities 13,360 5,625 18,985 Other long-term liabilities - 93 93 Unregistered contributed capital 3.11 4,000 (4,000) - Trade accounts payable 3.10 15,494 863 16,357 Advances received and other current liabilities 13,476 301 13,777 Corporate income tax payable 3.7 262 1,118 1,380 The most individually significant corrections are as follows: 3.1 Investments in associates and joint ventures The Group has an investments in associates PJSC Ukrnafta and PJSC Ukrtatnafta, which were previously accounted for on cost basis in the Group s consolidated financial statements for the year ended 2011. According to IAS 28 Investments in associates (IAS 28), application of equity method of accounting is required for the investments in associates. In order to align the accounting method with the requirements of IAS 28, the Group recalculated the retrospective effect on investments in PJSC Ukrnafta and PJSC Ukrtatnafta according to equity method, retrospectively from the investments initial recognition date. As at 1 January, the restated carrying value of investment in PJSC Ukrnafta and PJSC Ukrtatnafta per equity method comprised UAH 7,984 million and UAH 705 million (cost of investment in PJSC Ukrnafta and PJSC Ukrtatnafta, as reported earlier comprised UAH 4,250 million and UAH 836 million, respectively). 3.2 Technological oil and gas valuation According to the Group s accounting policies, the Group uses the revaluation model to measure items of property, plant and equipment, including technological oil and gas. The value of technological oil and gas as at 1 January was restated due to error, as it was not valued properly in the consolidated financial statements as at and for the year ended 2011. Also, management identified that as at 1 January part of natural gas accounted for as inventories had to be reclassified to technological gas in the amount of UAH 13,081 million. Value of technological oil and gas as at 1 January, including technological gas reclassified from inventories, was calculated with reference to the market prices, and after appropriate correction amounted to UAH 12,012 million and UAH 68,342 million, respectively (carrying amount was reported earlier as: UAH 2,527 million and UAH 18,615 million, respectively). Deferred tax position was also adjusted for the related effect. 18

3. RESTATEMENT OF COMPARATIVE INFORMATION (Continued) 3.3 Concession agreement The Company entered into Concession agreement for exploration and exploitation with the Arab Republic of Egypt and Egyptian General Petroleum Corporation ( EGPC ) on 13 December 2006. The parties established the JV Petrosannan that is accounted by the Group as joint operations. According to this agreement, the Group has a right to recover its exploration, development and other costs from EGPC to the extent of 25% of oil and gas produced by JV Petrosannan. Previously, in the consolidated financial statements for 2011 the Group charged all costs eligible for compensation to profit and loss, and made respective correction as at 1 January. Accordingly, the Group recognised UAH 1,117 million of compensation costs due from EGPC in other non-current assets as at 1 January. 3.4 Obligations on repurchase of State treasury bonds agreement Before 1 January, the Company received State treasury bonds from the Government of Ukraine as contribution to the share capital. These State treasury bonds were sold for cash with buy back obligation. The Group accounted for such operations as respective sale and subsequent purchase of State treasury bonds.

State treasury bonds received from the Government of Ukraine as contribution to share capital in the amount of UAH 4,166 million were accounted as non-current assets in the consolidated financial statements as at 2011. Such assets were reclassified as current within available-for-sale investments as it better reflects correctly their substance and management intent to sell them in short term. Respective reclassification was made as at 1 January. 3.5 Correction of natural gas inventory balance Subsequent to issuing the consolidated financial statements for 2011 management identified a cut off error in cost of gas sold and made respective correction of natural gas inventory balance as at 1 January by UAH 1,947 million. 3.6 Reversal of income and accounts receivable from fines and penalties Previously, the Group accounted for fines and penalties receivable with accrual of respective income upon Court successful decision without taking into account whether realisation of such income is virtually certain.
