PJSC LUKOIL MANAGEMENT S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

PJSC LUKOIL MANAGEMENT S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS for the three months ended 31 March 2018 and 2017 and 31 December 2017

The following report contains a discussion and analysis of the financial position of PJSC LUKOIL at 31 March 2018 and the results of its operations for the three months ended 31 March 2018 and 2017 and 31 December 2017, as well as significant factors that may affect its future performance. It should be read in conjunction with our International Financial Reporting Standards ( IFRS ) condensed interim consolidated financial statements for the respective periods. References to LUKOIL, the Company, the Group, we or us are references to PJSC LUKOIL and its subsidiaries and equity affiliates. All ruble amounts are in millions of Russian rubles ( RUB ), unless otherwise indicated. Income and expenses of our foreign subsidiaries were translated to rubles at rates which approximate actual rates at the date of the transaction. Tonnes of crude oil and natural gas liquids produced were translated into barrels using conversion rates characterizing the density of crude oil from each of our oilfields and the actual density of liquids produced at our gas processing plants. Hydrocarbon extraction expenses per barrel were calculated using these actual production volumes. Other operational indicators expressed in barrels were translated into barrels using an average conversion rate of 7.33 barrels per tonne. Translations of cubic meters to cubic feet were made at the rate of 35.31 cubic feet per cubic meter. Translations of barrels of crude oil into barrels of oil equivalent ( BOE ) were made at the rate of 1 barrel per BOE and of cubic feet at the rate of 6 thousand cubic feet per BOE. This report includes forward-looking statements words such as believes, anticipates, expects, estimates, intends, plans, etc. that reflect management s current estimates and beliefs, but are not guarantees of future results. 2

Business overview The primary activities of LUKOIL and its subsidiaries are hydrocarbon exploration, production, refining, marketing and distribution. LUKOIL is one of the world s largest publicly traded vertically integrated energy companies. Our proved reserves under SEC standards amounted to 16.0 billion BOE at 1 January 2018 and comprised of 12.1 billion barrels of crude oil and 23.6 trillion cubic feet of gas. Most of our reserves are conventional. We undertake exploration for, and production of, crude oil and natural gas in Russia and internationally. In Russia, our major oil producing regions are Western Siberia, Timan-Pechora, Ural and Volga region. Our international upstream segment includes stakes in PSA s and other projects in Kazakhstan, Azerbaijan, Uzbekistan, Romania, Iraq, Egypt, Ghana, Norway, Cameroon, Nigeria and Mexico. Our daily hydrocarbon production in the first quarter of 2018 amounted to 2.3 million BOE, with liquid hydrocarbons representing approximately 77% of our overall production volumes. LUKOIL has geographically diversified downstream assets portfolio primarily in Russia and Europe. Our downstream operations include crude oil refining, petrochemical and transport operations, marketing and trading of crude oil, natural gas and refined products, power generation, transportation and sales of electricity, heat and related services. We own and operate four refineries located in European Russia and three refineries located outside Russia in Bulgaria, Romania, and Italy. Moreover, we have a 45% interest in the Zeeland refinery in the Netherlands. We also own two petrochemical plants in Russia and have petrochemical capacities at our refineries in Bulgaria and Italy. Along with our own production of refined products we refine crude oil at third party refineries depending on market conditions and other factors. Our refinery throughput in the first quarter of 2018 amounted to 1.3 million barrels per day, and we produced 0.3 million tonnes of petrochemicals. We market our own and third-party crude oil and refined products through our wholesale and retail channels in Russia, Europe, South-East Asia, Central and North America and other regions. We own petrol stations in 18 countries. Most of our retail networks are located close to our refineries. Our retail sales in the first quarter of 2018 amounted to 3.4 million tonnes of refined products. We are involved in production, distribution and marketing of electrical energy and heat both in Russia and internationally. In the first quarter of 2018, our total output of electrical energy was 5.3 billion kwh. Our operations and finance activities are coordinated from our headquarters in Moscow. We divide our operations into three main business segments: Exploration and production, Refining, marketing and distribution, and Corporate and other. 4

(2) Cash flow from operating activities less capital expenditures. Our results were positively impacted by an increase in share of high-margin projects in crude oil production structure, growth in gas production volumes in Russia and Uzbekistan, better product slate at our refineries, a decrease in transportation, operating, selling, general and administrative expenses and an increase in international hydrocarbon prices. Among the negative factors were lower benchmark refining margins, decrease in positive export duty lag effect, strengthening of the ruble to the US dollar, as well as external limitations of our liquids production in Russia due to the OPEC agreement and higher excise tax and mineral extraction tax rates in Russia. Our profit was positively impacted by a decrease in net monetary position in foreign currencies and negatively impacted by increased depreciation, depletion and amortization. As a result, in the first quarter of 2018, profit attributable to LUKOIL shareholders amounted to 109 billion RUB, a decrease of 9.5% to the fourth quarter of 2017 and an increase of 75.0% to the first quarter of 2017. Our EBITDA amounted to 220 billion RUB, a decrease of 1.9% to the fourth quarter of 2017, and an increase of 5.7% to the first quarter of 2017. Our free cash flow decreased by 27.4 billion RUB, or by 37.3%, compared to the fourth quarter of 2017 and increased by 44.6 billion RUB compared to the first quarter of 2017. Our free cash flow was positively impacted by lower capital expenditures and negatively affected by changes in working capital. The Group s average daily hydrocarbon production in the first quarter of 2018 increased by 0.2% compared to the fourth quarter of 2017, and by 3.4% compared to the first quarter of 2017, driven primarily by growth in gas production volumes due to commissioning of new facilities at our projects in Uzbekistan. Planned increase in production from V.Filanovsky and Pyakyakhinskoe fields, commissioned in 2016, continued. In the first quarter of 2018, throughput at own refineries decreased by 4.8% compared to the fourth quarter of 2017, and by 0.5% compared to the first quarter of 2017 due to maintenance works. At the same time, we achieved further improvement in refined product slate due to modernization of our refining capacities in Russia and feedstock optimization. 5

Changes in Group structure In December 2016, the Company entered into a contract with a company of the Otkrytie Holding group to sell the Group s 100% interest in JSC Arkhangelskgeoldobycha ( AGD ), a company developing the diamond field named after V.P. Grib located in Arkhangelsk region of Russia. The transaction in the amount of Russian ruble equivalent of $1.45 billion was completed on 24 May 2017 after all necessary governmental approvals were received. As a result the Group recognized profit before income tax in the amount of 48 billion RUB that is included in Other income (expenses) in the consolidated statement of profit or loss and other comprehensive income (profit after income tax 38 billion RUB). In February 2017, the Group completed the sale of wholly owned subsidiary LUKOIL Chemical B.V., which owns Karpatneftekhim petrochemical plant located in the Ivano-Frankovsk area of Ukraine. 6

Main macroeconomic factors affecting our results of operations International crude oil and refined products prices The price at which we sell crude oil and refined products is the primary driver of the Group s revenues. The dynamics of our realized prices on international markets generally matches the dynamics of commonly used spot benchmarks such as Brent crude oil price, however our average prices are usually different from such benchmarks due to different delivery terms, quality mix, as well as specifics of regional markets in case of petroleum product sales. In the first quarter of 2018, the price for Brent crude oil fluctuated between $61 and $71 per barrel, reached its maximum of $70.7 in early January and its minimum of $61.5 in early February. Average price expressed in US dollars increased by 8.7% compared to the fourth quarter of 2017 and by 24.4% compared to the first quarter of 2017. Nevertheless, as a result of the ruble appreciation, the prices expressed in rubles increased less significantly. The following tables show the average crude oil and refined product prices.

Domestic crude oil and refined products prices Most of the crude oil in Russia is produced and then refined or exported by vertically integrated oil companies. As a result, there is no liquid spot market for crude oil in Russia and no publicly available spot price benchmark. Domestic prices may deviate significantly from export netbacks and they also vary between different regions of Russia driven by supply demand balance on regional markets. Domestic prices for refined products correlate to some extent with export netbacks, but are also materially affected by supply demand balance on regional markets. 7

The table below represents average domestic wholesale prices for refined products for the respective periods.

Changes in ruble exchange rate and inflation A substantial part of our revenue is either denominated in US dollars or euro or is correlated to some extent with US dollar crude oil prices, while most of our costs are settled in Russian rubles. Therefore, a devaluation of the ruble against the US dollar and euro generally causes our revenues to increase in ruble terms, and vice versa. Ruble inflation also affects the results of our operations. The following table provides data on inflation in Russia and change in the ruble-dollar and the ruble-euro exchange rates. Ruble inflation (CPI), %... 0.8 0.8 0.8 1.0 Ruble to US dollar exchange rate Average for the period... 56.9 58.4 56.9 58.8 At the beginning of the period... 57.6 58.0 57.6 60.7 At the end of the period... 57.3 57.6 57.3 56.4 Ruble to euro exchange rate Average for the period... 69.9 68.8 69.9 62.6 At the beginning of the period... 68.9 68.4 68.9 63.8 At the end of the period... 70.6 68.9 70.6 60.6 Source: CBR, Federal State Statistics Service. Taxation Between 2015 and 2017, the Russian Government implemented the tax manoeuvre in the oil industry which involved reduction of export duty rate and increase in the crude oil extraction tax and excise tax rates. Changes that became effective from January 2017 had a positive impact on our upstream margins and a negative impact on our refining and marketing margins, while overall impact of tax changes on our financial results wasn t significant. The following tables represent average enacted rates for taxes specific to the oil industry in Russia for the respective periods.

The methods to determine the rates for such taxes are presented below. Crude oil extraction tax rate is changed monthly. Crude oil extraction tax is payable in rubles for metric tonnes extracted and is calculated according to the formula below: Exchange Rate Rate = Base Rate (Price 15) Incentive + Fixed Factor, 261 where Price is a Urals blend price in US dollars per barrel and Exchange Rate is an average ruble exchange rate to US dollar during the period. The Base Rates and Fixed Factors (where applicable) are presented below: 2021 and 2017 2018 2019 2020 further (rubles) Base Rate... 919 919 919 919 919 Fixed Factor... 306 357 428 428 0 There are different types of tax incentives on the mineral extraction tax on crude oil applied to our fields and deposits: A special reducing coefficient is applied to the standard tax rate depending on location, depletion, type of reserves, size and complexity of a particular field. This type of incentive with different coefficients is applied to our highly depleted fields (more than 80% depletion), our Yu. Korchagin field located in the Caspian offshore, the Permian layers of our Usinskoye field in Timan-Pechora producing high-viscous crude oil, our Pyakyakhinskoye field located in the Yamal-Nenets Autonomous region of Western Siberia, a number of fields in the Nenets Autonomous region, as well as to our new small-sized fields (recoverable reserves less than 5 million tonnes) and fields and deposits with low permeability like V.N. Vinogradov field and Tyumen deposits; 9

A fixed tax rate of 15% of the international Urals price is applied to our V. Filanovsky field, located in the Caspian offshore; A zero tax rate is applied to our Yaregskoye field producing extra-viscous crude oil, as well as to particular unconventional deposits. Some of the mineral extraction tax incentives are limited in time or by cumulative oil production volumes. The table on the p. 9 illustrates the impact of crude oil extraction tax incentives on taxation of crude oil production from our different fields and deposits at $50 per barrel Urals price. Natural gas extraction tax rate is calculated using a special formula depending on average wholesale natural gas price in Russia, the share of gas production in particular taxpayer s total hydrocarbon production, regional location and complexity of particular gas field. Associated petroleum gas and reinjected natural gas are subject to zero extraction tax rate. Crude oil export duty rate is denominated in US dollars per tonne of crude oil exported and is calculated on a progressive scale according to the table below. International Urals price Less than, or equal to, $109.5 per tonne ($15 per barrel) Above $109.5 but less than, or equal to, $146.0 per tonne ($20 per barrel) Above $146.0 but less than, or equal to, $182.5 per tonne ($25 per barrel) Above $182.5 per tonne ($25 per barrel) Export duty rate $0 per tonne 35% of the difference between the actual price and $109.5 per tonne (or $0.35 per barrel per each $1 increase in crude oil price over $15 per barrel) $12.78 per tonne plus 45% of the difference between the actual price and $146 per tonne (or $1.75 plus $0.45 per barrel per each $1 increase in crude oil price over $20 per barrel) $29.2 per tonne plus 30% of the difference between the actual price and $182.5 per tonne (or $4 plus $0.3 per barrel per each $1 increase in crude oil price over $25 per barrel) The export duty rate changes every month with the rate for the next month being based on average Urals price for the period from the 15 th day of the previous month to the 14 th day of the current month. This calculation methodology results in the so-called export duty lag effect, when export duty rate lags the oil price changes, which may result in sizeable impact on our financial results in the periods of high oil price volatility. The table below illustrates the impact of the export duty lag effect on the Urals price net of taxes.

(2) Translated to rubles using average exchange rate for the period. Crude oil produced at some of our fields is subject to special export duty rates calculated according to specified formulas, which are lower than standard rates. A reduced rate is applied to crude oil produced at our Yaregskoye field producing extra-viscous crude oil and our Yu. Korchagin field in the Caspian offshore. A zero rate applies to crude oil of our V. Filanovsky field also located in the Caspian offshore. The table on p. 9 illustrates the impact of crude oil export duty incentives on taxation of export of crude oil produced from our different fields and deposits at $50 per barrel Urals price. 10

Export duty rates on refined products are calculated by multiplying the current crude oil export duty rate by a coefficient according to the table below. 2017 and further Multiplier for: Light and middle distillates... 0.30 Diesel fuel... 0.30 Gasolines... 0.30 Straight-run gasoline... 0.55 Fuel oil... 1.00 Crude oil and refined products exported from Russia are subject to two steps of customs declaration and duty payments: temporary and complete. A temporary declaration is submitted based on preliminary exports volumes and the duty is paid in rubles translated from US dollars at the date of the temporary declaration. A complete declaration is submitted after receiving the actual data on the exported volumes, but no later than six months after the date of the temporary declaration. The final amount of the export duty is adjusted depending on the actual volumes, the ruble-us dollar exchange rate at the date of the complete declaration (except for pipeline deliveries for which the exchange rate at the temporary declaration date is used) and the export duty rate. If temporary and complete declarations are submitted in different reporting periods, the final amount of the export duty is adjusted in the period of submission of the complete declaration. The high volatility of the ruble-dollar exchange rates may lead to significant adjustments. For the purposes of the IFRS consolidated financial statements, data from temporary declarations at the reporting period end is translated to rubles from US dollars using the period-end exchange rate. Crude oil and refined products exported to member countries of the Customs Union in the Eurasian Economic Union of Russia, Belarus, Kazakhstan, Armenia and the Kyrgyz Republic (Customs Union) are not subject to export duties. Excise taxes on refined products. The responsibility to pay excises on refined products in Russia is imposed on refined product producers (except for straight-run gasoline). Only domestic sales volumes are subject to excises. In other countries where the Group operates, excise taxes are paid either by producers or retailers depending on the local legislation. Excise rates on motor fuels in Russia are tied to the ecological class of fuel. Excise tax rates for the periods considered are listed below.

Income tax. The federal income tax rate in Russia is 3.0% and the regional income tax rate may vary between 12.5% and 17.0%. The Company and its Russian subsidiaries file income tax returns in Russia. A number of Group companies in Russia are paying income tax as a consolidated taxpayers group ( CTG ). This allows taxpayers to offset taxable losses generated by certain participants of a CTG against taxable profits of other participants of the CTG. The Group s foreign operations are subject to taxes at the tax rates applicable to the jurisdictions in which they operate. Transportation tariffs on crude oil, natural gas and refined products in Russia Many of our production assets are located relatively far from our customers. As a result, transportation tariffs are an important factor affecting our profitability. Сrude oil produced at our fields in Russia is transported to refineries and exported primarily through the trunk oil pipeline system of the state-owned company, Transneft. In some cases, crude oil is also transportated via railway infrastructure of the state-owned company, Russian Railways. Refined products produced at our Russian refineries are transported primarily by railway (Russian Railways) and the pipeline system of Transnefteproduct, a subsidiary of Transneft. Gas that is not sold at the wellhead is transported through the Unified Gas Supply System owned and operated by Gazprom. Transneft, Russian Railways and Gazprom are state-controlled natural transportation infrastructure monopolies and their tariffs are regulated by the Federal Antimonopoly Service of Russia and set in rubles. The following table sets forth the changes in the average tariffs charged by the state-controlled transportation service providers in Russia. 1 st quarter of 2018 to 4 th quarter of 2017 1 st quarter of 2018 to 1 st quarter of 2017 Transneft Crude oil... 4.0% 4.2% Russian Railways Crude oil and refined products... 5.3% 5.3% 12

Segments highlights Our operations are divided into three main business segments: Exploration and Production which includes our exploration, development and production operations related to crude oil and gas. These activities are primarily located within Russia, with additional activities in Azerbaijan, Kazakhstan, Uzbekistan, the Middle East, Northern and Western Africa, Norway, Romania and Mexico. Refining, Marketing and Distribution which includes refining, petrochemical and transport operations, marketing and trading of crude oil, natural gas and refined products, generation, transportation and sales of electricity, heat and related services. Corporate and other which includes operations related to our headquarters (which coordinates the operations of Group companies), finance activities, and certain other activities, that are not primary to the Group. Each of our segments is dependent on the others, with a portion of the revenues of one segment being a part of the costs of the others. In particular, our Refining, Marketing and Distribution segment purchases crude oil from our Exploration and Production segment. As a result of certain factors considered in the Domestic crude oil and refined products prices section on p. 7, benchmark crude oil market prices in Russia cannot be determined with certainty. Therefore, the prices set for inter-segment purchases of crude oil reflect a combination of market factors, primarily international crude oil market prices, transportation costs, regional market conditions, the cost of crude oil refining and other factors. We present the financial data for each segment in Note 28 Segment information to our consolidated financial statements. Exploration and production The following table summarizes key figures on our Exploration and production segment: EBITDA... 171,918 172,961 171,918 127,777 - in Russia... 144,657 149,816 144,657 112,059 - outside Russia (1)... 27,261 23,145 27,261 15,718 Hydrocarbon extraction expenses... 50,670 54,794 50,670 49,867 - in Russia... 42,857 46,311 42,857 42,952 - outside Russia and Iraq... 4,238 4,989 4,238 2,593 - in Iraq... 3,575 3,494 3,575 4,322 (ruble per BOE) Hydrocarbon extraction expenses (excluding Iraq)... 235 251 235 237 - in Russia... 244 257 244 243 - outside Russia and Iraq... 176 205 176 167 (US dollar per BOE) Hydrocarbon extraction expenses (excluding Iraq)... 4.14 4.30 4.14 4.02 - in Russia... 4.28 4.41 4.28 4.13 - outside Russia and Iraq... 3.09 3.51 3.09 2.84 (1) Including EBITDA of the West Qurna-2 project in the amounts of 5,735 million RUB in the first quarter of 2018, and 2,943 million RUB and 4,603 million RUB in the first and fourth quarters of 2017, respectively. Our upstream EBITDA decreased by 0.6%, compared to the fourth quarter of 2017, and increased by 34.5%, compared to the first quarter of 2017. Our upstream EBITDA in Russia decreased compared to the fourth quarter of 2017 despite higher hydrocarbon prices due to lower positive export duty lag effect and the ruble appreciation to the US dollar, and increased compared to the first quarter of 2017 as a result of higher hydrocarbon prices and increase in production from our high-margin fields. Outside Russia, our EBITDA increased significantly compared to both the fourth and the first quarters of 2017 due to higher hydrocarbon prices, increase in gas production and increased EBITDA of the West Qurna-2 project. 13

Our main oil producing region is Western Siberia where we produced 44.3% of our crude oil in the first quarter of 2018 (44.7% in the fourth quarter of 2017, 46.5% in the first quarter of 2017). Compared to the fourth quarter of 2017, daily liquids production in Russia didn t change significantly. The decrease in our production volumes compared to the first quarter of 2017, was mainly driven by a temporary external limitation due to an agreement of OPEC and some of the non-opec countries, including Russia, to cut production from October 2016 levels in order to stabilize the global crude oil market. We limited production in our traditional regions (Western Siberia, Timan-Pechora, Ural) by closing least-productive wells, wells with high water cut and high lifting costs. We also decreased a number of workover operations. At the same time we continued increasing production at the V. Filanovsky and Pyakyakhinskoye fields and other high-margin fields, which have a major positive impact on our financial results due to high quality reserve base and tax incentives. In the first quarter of 2018, we produced 1,365 thousand tonnes of crude oil at the V. Filanovsky field and 388 thousand tonnes of liquids at the Pyakyakhinskoye field, an increase by 54% and 12%, respectively, compared to the first quarter of 2017. Active development of the Yaregskoye field and the Permian layers of our Usinskoye field in Timan-Pechora led to the increase in the high-viscous crude oil production by 45% compared to the first quarter of 2017. 15

Gas production (excluding flaring, reinjected gas and gas used in production of natural gas liquids) by major regions is presented in the table below. (millions of cubic meters) Western Siberia... 3,318 3,356 3,318 3,193 Timan-Pechora... 515 538 515 551 Ural region... 229 240 229 258 Volga region... 404 414 404 297 Other in Russia... 7 8 7 8 Gas produced in Russia... 4,473 4,556 4,473 4,307 Gas produced outside Russia... 3,343 3,413 3,343 1,924 Total gas produced by consolidated subsidiaries... 7,816 7,969 7,816 6,231 Our share in gas produced by equity affiliates: in Russia... 23 25 23 23 outside Russia... 160 199 160 205 Total gas produced... 7,999 8,193 7,999 6,459 Our major gas production region is Western Siberia (Bolshekhetskaya depression), where the major part of gas is produced from the Nakhodkinskoe field, which has been developed since 2005. In January 2017, we started gas production from our second field in Bolshekhetskaya depression, the Pyakyakhinskoye field, which substantially contributed to our overall gas production in Russia that increased by 3.9%, compared to the first quarter of 2017. Gas production from Pyakyakhinskoe field amounted to 932 million cubic meters. Our daily international gas production (including our share in affiliates production) increased by 64.5%, compared to the first quarter of 2017, as a result of commissioning of new gas treatment facilities within Gissar and Kandym projects in Uzbekistan. Compared to the fourth quarter of 2017, our daily gas production both in Russia and internationally didn t change significantly. West Qurna-2 project The West Qurna-2 field in Iraq is one of the largest crude oil fields discovered in the world, with initial estimated recoverable oil reserves of 12.9 billion barrels (1.8 billion tonnes). Service agreement for the West Qurna-2 field development and production was signed on 31 January 2010. Currently, the parties of the project are Iraq s state-owned South Oil Company and a consortium of contractors, consisting of a Group company (75% interest) and Iraq s state-owned North Oil Company (25% interest). The Group launched the Mishrif Early Oil stage on the field and reached the production of 120 thousand barrels per day in March 2014. According to the service agreement, starting from the second quarter of 2014, we receive cost compensation. The total term of the contract is 25 years. In May 2018, a Group company and Iraqi party signed a development plan of West Qurna-2 field, according to which, the oil production of 480 thousand barrels per day will be reached in 2020 and 800 thousand barrels per day is expected in 2025. Accounting for the cost compensation within the West Qurna-2 project in our consolidated statement of financial position and consolidated statement of profit or loss and other comprehensive income is as follows. Capital expenditures are recognized in Property, plant and equipment. Extraction expenses are recognized in Operating expenses in respect of all the volume of crude oil production at the field regardless of the volume of compensation crude oil the Group is eligible for. As the compensation revenue is recognized, capitalized costs are amortized. There are two steps of revenue recognition: The Iraqi party, on a quarterly basis, approves invoice for cost recovery and remuneration fee for which the Group is eligible in the reporting period. Amount of the invoice depends on crude oil production volumes during the period and amount of costs claimed for reimbursement. Approved invoice amount and remuneration fee for the reporting quarter are recognized in crude oil sales revenue. 16

Based on the approved invoices, the Iraqi party arranges schedule of crude oil shipments against its liability for cost compensation and remuneration. As this crude oil is actually shipped, its cost is recognized at current market price in Cost of purchased crude oil, gas and products. Further, revenue from sales of this crude oil, or products from its refining, is recognized in Sales. Unsold crude oil and refined products are recognized in Inventories. The following table summarizes data on capital and operating costs incurred, compensation crude oil received, costs yet unrecovered and remuneration fee. Сosts incurred (1) Remuneration fee Crude oil received Crude oil to be received (millions of US dollars) Cumulative at 31 December 2017... 8,072 303 7,842 533 Change in the first quarter of 2018... 112 28 121 19 Income tax (2)...

In February-June 2017, due to a so-called performance factor that represents a ratio of actual production volumes to target production volumes according to the provisions of the service contract, our per barrel remuneration fee was approximately three times lower. The parties agreed not to apply the performance factor from the third quarter of 2017. Refining, marketing and distribution The following table summarizes key figures on our Refining, marketing and distribution segment: EBITDA... 46,849 49,009 46,849 70,527 - in Russia... 42,299 39,267 42,299 37,847 - outside Russia... 4,550 9,742 4,550 32,680 Refining expenses at the Group refineries... 22,019 23,050 22,019 21,011 - in Russia... 9,538 11,182 9,538 10,149 - outside Russia... 12,481 11,868 12,481 10,862 (ruble per tonne) Refining expenses at the Group refineries... 1,366 1,333 1,366 1,297 - in Russia... 895 1,003 895 966 - outside Russia... 2,287 1,930 2,287 1,909 (US dollar per tonne) Refining expenses at the Group refineries... 24.02 22.82 24.02 22.05 - in Russia... 15.74 17.18 15.74 16.42 - outside Russia... 40.20 33.04 40.20 32.44 In the first quarter of 2018, our Refining, marketing and distribution EBITDA was 4.4% lower than in the fourth quarter of 2017 and 33.6% lower than in the first quarter of 2017. In Russia, our downstream EBITDA increased by 7.7% compared to the fourth quarter of 2017. Lower profitability of Russian refineries as a result of the negative inventory effect and lower benchmark refining margins was offset by improved performance of our petrochemical and power generation businesses, better product slate and lower expenses at our refineries, as well as improved performance of our priority sales channels. Compared to the first quarter of 2017, our downstream EBITDA in Russia increased by 11.8% due to better product slate at our refineries, higher throughput volumes and decrease in refining expenses, as well as the expansion of our priority sales channels. Compared to the fourth quarter of 2017, our downstream EBITDA outside Russia decreased as a result of lower benchmark refining margins and maintenance works at our refineries. The year-on-year dynamic of our downstream EBITDA outside Russia was mainly defined by accounting specifics of our trading operations that resulted in material gains in the first quarter of 2017. 18

The total volume of refined products produced by the Group decreased by 7.5%, compared to the fourth quarter of 2017, and by 1.0%, compared to the first quarter of 2017. Compared to the fourth quarter of 2017, production at our refineries in Russia decreased by 4.2% as a result of the maintenance works. Compared to the first quarter of 2017, production increased by 1.6%, mainly due to higher utilization rates at our refinery in Volgograd. In Russia, we continued improving our refined product slate through higher utilization rates of our newly-launched conversion facilities and crosssupplies of own dark products to catalytic cracking units at our refineries in Nizhny Novgorod and Volgograd and to coking unit in Perm. As a result, the share of gasoline and diesel fuel in our total production volumes increased by 5.6 p.p. compared to the first quarter of 2017 and the share of fuel oil and vacuum gasoil decreased by 6.6 p.p. At our international refineries, production declined as a result of maintenance works. Due to the change in price environment, the volume of crude oil processed decreased, while the volume of refined product processed increased. In the periods considered, we processed our crude oil at third party refineries in Belarus, Kazakhstan and Canada. In 2016, a Group company entered into a tolling agreement with a Canadian refinery. In the first quarter of 2018, attributable refined products output amounted to 1.6 million tonnes (1.3 million tonnes and 1.7 million tonnes in the first and the fourth quarters of 2017, respectively). The agreement is valid through 2019. 19

Marketing and trading In addition to our production, we purchase crude oil in Russia and on international markets. In Russia, we primarily purchase crude oil from affiliated producing companies and other producers. Then we either refine or export purchased crude oil. Crude oil purchased on international markets is used for trading activities, for supplying our international refineries or for processing at third party refineries. In Russia, we purchase refined products on occasion, primarily to manage supply chain bottlenecks. Refined products purchases outside Russia are either traded or supplied to our international refineries. We undertake trading operations on international markets through our 100% subsidiary LITASCO. We use traditional physical volumes hedging techniques to hedge our trading operations to secure trading margin. The following table shows the volumes of crude oil purchases by the Group during the periods considered.
