This report contains certain forward-looking statements in particular under the section "Outlook" regarding capital expenditures, development and management of oil and gas resources, dividends, allocation of future cash flow from operations, future operating performance, gearing, targets of production and sale growth, new markets, and the progress and timing of projects. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that will or may occur in the future. Actual results may differ from those expressed in such statements, depending on a variety of factors, including the timing of bringing new fields on stream; management’s ability in carrying out industrial plans and in succeeding in commercial transactions; future levels of industry product supply; demand and pricing; operational problems; general economic conditions; political stability and economic growth in relevant areas of the world; changes in laws and governmental regulations; development and use of new technology; changes in public expectations and other changes in business conditions; the actions of competitors and other factors discussed elsewhere in this document.
Due to the seasonality in demand for natural gas and certain refined products and the changes in a number of external factors affecting Eni’s operations, such as prices and margins of hydrocarbons and refined products, Eni’s results of operations and changes in net borrowings for the first half of the year cannot be extrapolated for the full year.

"Eni" means the parent company Eni SpA and its consolidated subsidiaries.

Financial highlights - Net profit attributable to Eni’s shareholders for the first half of 2011 amounted to euro 3.8 billion. Adjusted operating and net profit amounted to euro 9.1 billion and euro 3.6 billion, respectively, increasing by 7.6% and 4.2% from the first half of 2010. The main driver was the strong operating performance of the Exploration & Production segment (up 21%) driven by a strong oil price environment, partly offset by the impact associated with a lowered Libyan output and the appreciation of the euro vs. the US dollar. Also the Engineering & Construction segment posted higher profit due to improved performance. These positives were offset by a weak performance of the downstream gas and refining businesses. The Gas & Power Division’s and the Group performance did not take into account the possible benefit associated with ongoing renegotiations of the Company’s long-term gas purchase contracts which may become effective earlier than the end of June 2011. - Net cash generated by operating activities amounted to euro 8.6 billion and was used to fund growth and exploration expenditure for euro 6.62 billion, payment of the balance dividend for the fiscal year 2010 to Eni’s shareholders and to non-controlling interest by consolidated entities (for a total amount of euro 2.21 billion). As a result, net borrowings as of June 30, 2011, amounted to euro 25,978 million, representing a slight decrease of euro 141 million from December 31, 2010. Ratio of net borrowings to shareholders’ equity including non-controlling interest – leverage – was 0.47 at June 30, 2011, unchanged from December 31, 2010. - Capital expenditure amounting to euro 6.62 million mainly related to development and exploratory activities of which 96% outside Italy; upgrading of the fleet used in the Engineering & Construction Division; development and upgrading of Eni’s natural gas transport network in Italy. - In light of the financial results achieved for the first half of 2011 and management’s expectations for the full-year results, the interim dividend proposal to the Board of Directors on September 8, 2011, will amount to euro 0.52 per share (euro 0.50 per share in 2010). The interim dividend is payable on September 22, 2011, being September 19, 2011, the ex dividend date. Operational highlights - Eni reported liquids and gas production of 1,586 kboe/d in the first half of 2011, down by 12% from the first half of 2010, driven by the loss of Eni’s output in Libya. Net of lower entitlements in the Company’s PSAs due to higher oil prices and of the above mentioned loss of Libyan output, production for the first half decreased by 1%, mainly due to planned facility downtime. Production decline at mature fields was absorbed by continuing production ramp up in Norway, Egypt and Iraq. |  | - In line with production plans, new fields were started up in the period: Capparuccia (Eni’s interest 77.8%) in Italy, Libondo (Eni’s interest 35%) offshore Congo, Nikaitchuq (Eni operator with a 100% interest) offshore Alaska and Appaloosa (Eni’s interest 100%) in the Gulf of Mexico. - Exploration yielded positive results adding 415 mmbbl to Eni’s resource base. Main results were achieved in Venezuela with the Perla 4 and 5 appraisal wells in Block Cardon IV (Eni’s interest 50%), Angola, in the West Hub project in the rich Block 15/06 (Eni operator with a 35% interest), Norway, with the Skrugard oil and gas discovery to be readily put in production in the PL 532 (Eni’s interest 30%), with initial recoverable reserves of approximately 250 mmbbl. Other successes were achieved in the Gulf of Mexico, Ghana, the United Kingdom, Egypt, Pakistan and Indonesia. - Sales of natural gas amounted to 53.33 bcm, increasing by 7.3% from the first half of 2010 due to a better performance recorded on European and domestic markets. Sales volumes in Italy posted an 11.4% increase due to clients additions and higher offtakes in the power generation, wholesalers and industrial segments leading to a significant increase in the market share. Sales in European markets increased by 18.7% with main increases recorded in Turkey, France, UK/Northern Europe, Germany/Austria and the Iberian Peninsula. Update on Libyan situation All of Eni’s producing facilities came to halt including export through the GreenStream import pipeline, with the sole exception of the Wafa field where it is supporting local production of electricity. Plants and pipelines were put into safety status and no damage has been reported. Eni is technically able to resume the gas output at a level similar to the pre-crisis flows in 2010 once the situation has returned to normal. Since March 2011, Eni has evacuated all its personnel and suspended ongoing exploration and development activities. Eni’s production in Libya is currently flowing at a rate of approximately 50 kboe/d, down from the expected level of 280 kboe/d for the year. As of June 30, 2011, Eni’s net capital employed in Libya amounted to $2.04 billion ($2.5 billion as of December 31, 2010), including a 50% interest in GreenStream BV. Portfolio developments - In January 2011 Eni and PetroChina signed a Memorandum of Understanding to promote joint projects in conventional and non conventional hydrocarbon plays in China and outside China. A similar agreement has been signed on July 2011 with Sinopec. - In April 2011, Eni signed a cooperation agreement with Sonatrach to explore for and develop unconventional hydrocarbons, particularly shale gas plays in Algeria.

Eni Interim Consolidated Report / Operating review

Oil and gas production

Eni reported oil and gas production of 1,586 kboe/d for the first half of 2011, down 214 kboe/d or 11.9% from the first half of 2010. The magnitude of this reduction was the result of the shutdown of activities at all Eni’s producing sites in Libya and the closure of the GreenStream pipeline transporting gas from Libya to Italy, with the sole exception of the Wafa field which has been flowing at a level of approximately 50 kboe/d net to Eni with the full supply supporting local production of electricity. |  | Performance was also negatively impacted by lower entitlements in the Company’s PSAs due to higher oil prices with an overall effect of approximately 30 kbbl/d compared to the first half of 2010, in addition to the above mentioned loss of Libyan output amounting to approximately 170 kboe/d. Net of those effects, production decreased by 1 percentage point in the first half of 2011, mainly due to planned facility downtime, mainly in Italy. Production decline at mature fields was absorbed by continuing production ramp-up in Norway, Egypt and Iraq.

First oil is expected in 2013 at an initial rate of 75 kbbl/d, targeting a long-term production plateau of 240 kbbl/d to be reached in 2018. The project provides the construction of a refinery with a capacity of 350 kbbl/day that will allow also the treatment of intermediate streams from other PDVSA facilities. Eni and PDVSA are evaluating the possibility to anticipate to 2012 the early production phase by means of synergies with existing PDVSA facilities for transporting an initial production up to 10 kbbl/d. In 2011, upstream (treatment plants and pipelines) and downstream (refinery) engineering contracts will be awarded as well as drilling contracts. It is anticipated that approximately 10 wells will be drilled by the end of 2011. Eni agreed to finance part of PDVSA’s development costs for the anticipated production phase up to $1.5 billion. In addition, Eni will secure a tranche of the Junin 5 bonus and an additional financing to PDVSA for a total of $500 million to fund the construction of a power station in the Guira peninsula, confirming its commitment to sustainable development. Pre-development and appraisal activities were performed at the Perla gas field, located in the Cardon IV Block (Eni’s interest 50%) in the Gulf of Venezuela. The results of Perla 4 and 5 appraisal wells exceeded the initial resource estimation to approximately 16,000 bcf. The development plan provides for a production target of approximately 300 mmcf/d in 2013. The early production phase includes the utilization of the already successfully drilled wells and the installation of four production platforms. The development of Perla is currently planned to continue with the full field phase to reach a plateau production of 1,200 mmcf/d. Project sanction is expected by the end of 2011. Phase I of Corocoro producing field (Eni’s interest 26%) moved forward with the transport and installation of Central Production Facility to increase capacity at approximately 45 kboe/d. Australia and Oceania Australia In May 2011, Eni signed an agreement with MEO Australia Limited to farm-in the Heron and Blackwood gas discoveries in permit NT/P-68, located in the Timor Sea. Eni will acquire a 50% stake and operatorship in the first gas discovery by financing exploration activities relating to the drilling of two appraisal wells. Eni was granted an option to earn a 50% stake in Blackwood discovery by drilling one appraisal well in the area and performing seismic surveys. The agreement also provides an option to acquire an additional 25% in both the discoveries by financing the development plan required to reach a Final Investment Decision (FID). Development plan of Kitan oil field (Eni operator with a 40% interest) progressed. Start-up is expected at the end of 2011 with an initial production of 15 kbbl/d.

Sales of natural gas Sales of natural gas (including Eni’s own consumption, Eni’s share of sales made by equity-accounted entities and upstream sales in Europe and the Gulf of Mexico) for the first half of 2011 were 53.33 bcm registering an increase of 3.63 bcm, up 7.3% from the first half of 2010. Sales in Italy were 19.09 bcm increasing by 1.95 bcm from the first half 2010 (up 11.4%) due to higher spot sales (up 1.04 bcm), higher off-takes and positive effects of marketing initiatives aimed at boosting the client base and market share in main business segments (power generation up 0.76 bcm; industries up 0.65 bcm; wholesalers up 0.50 bcm). Sales to residentials registered a decrease due to lower |  | seasonal consumption (down 0.46 bcm). Sales to shippers which import gas to Italy decreased by 2.94 bcm (down 55%). This was due to reduced of takes and lower availability of Libyan gas resulting from the closure of the GreenStream importing pipeline. Sales in the European market increased by 4.33 bcm (or 18.7%) to 27.46 bcm reflecting growth achieved in key markets, except for Belgium, due to stronger competitive pressures and lower seasonal gas sales (down 0.78 bcm). Main increases were recorded in Turkey (up 1.82 bcm), France (up 1.12 bcm), Germany/Austria (up 0.67 bcm), UK/Northern Europe (up 0.64 bcm), and the Iberian peninsula (up 0.42 bcm).

Divestment of international pipelines As part of the agreement signed with the European Commission for the divestment of Eni’s interests in the German TENP, the Swiss Transitgas and the Austrian TAG gas transport pipelines, |  | interconnected with the Italian transport system, on June 10, 2011, Eni entered a purchase agreement with Italian Cassa Depositi e Prestiti SpA ("CDP") for the sale of its whole interest in Trans Austria Gasleitung GmbH representing 89% of outstanding shares, which give right to 94% of the entity’s earnings. Trans Austria Gasleitung GmbH is the company which owns the transport rights for the Austrian section of the pipeline that connects Russia to Italy. The divestment, subject to approval of the European Commission, provides for the payment of euro 483 million, plus the reimbursement of a shareholder loan granted by Eni to the company equal to euro 192 million. These amounts will be subject to review at the closing date as per market practice. The parties have also agreed upon earn-out mechanisms linked to the occurrence of certain events. The transaction, once finalized, will leave unaffected the ship-or-pay contract signed by Eni with TAG. Procedures are progressing for the divestment of Eni’s interest in the other two gas transport pipelines, the German TENP and the Swiss Transitgas. Capital expenditure In the first half of 2011, capital expenditure in the Gas & Power segment totaled euro 725 million and mainly related to: (i) developing and upgrading Eni’s transport network in Italy (euro 374 million); (ii) developing and upgrading Eni’s distribution network in Italy (euro 152 million); (iii) developing and upgrading Eni’s storage capacity in Italy (euro 131 million).

Refining

In the first half of 2011, refining throughputs on own account in Italy and outside Italy were 15.77 mmtonnes, down 1.10 mmtonnes from the first half of 2010, or 6.5%. Volumes processed in Italy (down by approximately 970 ktonnes, or 6.8%) registered a decline from the same period of 2010 reflecting lower volumes at the Livorno, Gela and Venezia refineries due to planned facility downtimes and lower capacity utilization in response to a weak market environment. These negatives were partly offset by the higher volumes processed at the Sannazzaro, Milazzo and Taranto refineries reflecting the optimization of refining cycles and fewer downtimes. |  | Volumes processes outside Italy declined by 130 ktonnes, or down 5.1%, mainly in Germany and, at a lower extent, in the Czech Republic due to shrinking consumption. Total throughputs at wholly-owned refineries (11.22 mmtonnes) declined by 1.18 mmtonnes, down 9.5%, from the first half of 2010, resulting in a 78% utilization rate as a consequence of negative market trends. Approximately 23% of volumes of processed crude were supplied by Eni’s Exploration & Production segment (16.8% in the first half of 2010) corresponding to a higher volume of approximately 760 ktonnes or 6.2%.

Eni Interim Consolidated Report / Operating review

Retail sales in Italy In the first half of 2011, retail sales in Italy (4.08 mmtonnes) decreased from the first half of 2010 (down by approximately 100 ktonnes, or 2.4%). These reductions were mainly due to lower consumption of gasoline and, to a lesser extent, of gasoil, in particular relating to sales on motorways which were negatively impacted by the current decline in motor freight. Average throughput of gasoline and gasoil (1,068 kliters) declined by approximately 62 kliters from the first half of 2010. Eni’s retail market share for the first half of 2011 was 30.1% down 0.2 percentage points from the corresponding period of 2010 (30.3%). As of June 30, 2011, Eni’s retail network in Italy consisted of 4,644 units, an increase of 102 units from December 31, 2010 (4,542 service stations), resulting from the positive balance of acquisitions/releases of lease concessions (98 units), the opening of new service stations (11 units), which were partially offset by the closing of low throughput service stations (7 units). In February 2010, to substitute the promotional campaign "You&Agip", Eni launched the new fidelity program "you&eni" which will last for 3 years until January 31, 2013. As of June 30, 2011, the number of cards used by customers amounted to approximately 5.8 million. The average number of cards active each month was approximately 2.6 million. Volumes of fuel marketed under this initiative represented about 40% of overall volumes marketed on Eni’s network. Retail sales in the Rest of Europe In the first half of 2011, retail sales of refined products marketed in the rest of Europe (1.46 mmtonnes) increased by 1.4% from the same period of 2010, in particular in Austria due to the purchase of a service station network finalized in 2010. This increase was offset by declines mainly recorded in Germany, France, Hungary and Slovenia. At June 30, 2011, Eni’s retail network in the rest of Europe consisted of 1,612 units, a decrease of 13 units from December 31, 2010 (1,625 service stations). The network evolution was as follows: (i) 14 low |  | throughput service stations were closed; (ii) negative balance of acquisitions/releases of lease concessions (7 units) with negative changes in Austria and Switzerland; (iii) purchased 4 service stations; (iv) opening of 4 new service stations. Average throughput (1,111 kliters) declined from the first half of 2010 (1,175 kliters) by approximately 64 kliters. Wholesale sales and other sales In the first half of 2011, sales volumes on wholesale markets in Italy (4.41 mmtonnes) slightly increased from the first half of 2010 (up by approximately 40 mmtonnes, or 0.9%), mainly reflecting higher sales of jet fuel, bitumen and coke, offset in part by lower sales of gasoil, bunkering and fuel oil, due to lower demand. Supplies of feedstock to the petrochemical industry (approximately 850 ktonnes) decreased slightly by approximately 30 ktonnes due to declining industrial demand. Sales on wholesale markets in the rest of Europe (1.78 ktonnes) decreased from the first half of 2010 mainly due to lower sales in the Czech Republic, Germany and Slovenia, offset in part by increased sales in Austria. Other sales (8.58 mmtonnes) decreased by 1.16 mmtonnes, or 11.9%, mainly due to lower volumes sold to other oil companies. Capital expenditure In the first half of 2011, capital expenditure in the Refining & Marketing segment amounted to euro 316 million and regarded mainly: (i) refining, supply and logistics in Italy and outside Italy (euro 249 million), with projects designed to improve the conversion rate and flexibility of refineries, in particular at Sannazzaro plant, as well as expenditures on health, safety and environmental upgrades; (ii) building, upgrading and rebranding of service stations in Italy and in the Rest of Europe (euro 61 million). Expenditures on health, safety and the environment amounted to euro 41 million.

Sales - production - prices In the first half of 2011 sales of petrochemical products (2,170 ktonnes) decreased by 307 ktonnes (or 12.4%) from the first half of 2010 due to a steep decrease in demand negatively impacted by expectations for a reduction of prices of petrochemical commodities as well as lower product availability due to planned facility downtimes, in particular in the second quarter of 2011. Petrochemical production (3,348 ktonnes) decreased by 401 ktonnes from the first half of 2010, or 10.7%, with reductions both in basic petrochemicals and polymers (mainly in polyethylene, with increases on styrene and elastomers) due to the above mentioned lower demand and planned facility downtimes in the Italian sites of Priolo, Porto Marghera and Mantova, the |  | slow restart of the Dunkerque plant after the planned facility downtimes as well as the closure of the Feuly plant. Nominal production capacity was slightly higher than the first half of 2010 due to the realization of a new polyethylene production line in the Dunkerque site. The average plant utilization rate, calculated on nominal capacity, decreased from 76% to 66% as a result of lower volumes produced. Average unit prices increased by 27% from the first half of 2010. Steep increases were registered in the average prices of olefins and aromatics (up 25%) driven by an improved scenario with relevant increases in virgin naphtha, as well as polymers, in particular elastomers (up 35%) driven by higher demand.

Business Trends Basic petrochemicals Basic petrochemical revenues (euro 1,670 million) increased by euro 187 million (up 12.6%) from the first half of 2010 in all the main business segments due to the steep increase in average unit prices (olefins/aromatics up 25% and intermediates up 16%) notwithstanding a decrease of sales volumes (down 13% on average). Main decreases were registered in the sales volumes of olefins and aromatics due to product unavailability as a result of planned facility downtimes in the Priolo and Porto Marghera plants. In addition intermediates sales volumes decreased due to unavailability of raw material and planned facility downtimes in the Mantova plant. Basic petrochemical production (2,207 ktonnes) decreased by 329 ktonnes from the first six months of 2010 (down 13%) due to lower sales/demand of monomers and the above mentioned planned facility downtimes. Polymers Polymers revenues (euro 1,779 million) increased by euro 183 million from the first half of 2010 (up 11.5%) due to average unit prices increasing by 23% for styrenic polymers, 35% for elastomers and 27% for polyethylene. Sales volumes decreased on average by 12% negatively influenced by lower sales of polyethylene (down 18%) due to the delay in the restart of Dunkerque production line and lower demand relating to expectations for a reduction of prices of petrochemical commodities on the marketplace. In addition in the first half of 2011 were registered also lower sales volumes of styrenic polymers (down 7%) and stable sales of elastomers. Polymers production (1,140 ktonnes) decreased by 72 ktonnes from the first half of 2010 (down 6%) mainly due to lower production volumes of polyethylene (down 14%), partly offset |  | by the volumes increases of styrene and elastomers (up 2% and 9%, respectively). Lower production volumes of polyethylene were mainly related to the above mentioned delays in the Dunkerque plant. Portfolio developments Bio-based chemical In June 2011, through its subsidiary Polimeri Europa, Eni signed a cooperation agreement with Novamont SpA to convert Eni’s Porto Torres chemical plant into an innovative bio-based chemical complex to produce bioplastics and other bio-based petrochemical products (bio-lubricants and bio-additives) for which significant growth is expected in the medium-long term. The project will be supported by an integrated supply chain and raw materials of vegetable origin. Novamont will contribute its technologies and skills in the bio-plastics and bio-based chemical sector. Eni will contribute to the joint entity the Porto Torres plant, infrastructure and professional staff as well as its industry and technical-engineering and commercial know-how in the petrochemical sector. In addition, Eni foresees to build a biomass power plant and to carry out a number of projects for environmental restoration and clean-up activities. Eni plans to make capital expenditure totaling approximately euro 1.2 billion in the 2011-2016 period to execute the above mentioned projects directly or through the joint entity. Capital expenditure In the first half of 2011 capital expenditure amounted to euro 115 million (euro 71 million in the first half of 2010) and mainly related upkeeping (euro 34 million), energy recovery (euro 30 million), plant upgrades (euro 25 million) and environmental regulation compliance (euro 20 million).

Net profit Net profit attributable to Eni’s shareholders for the first half of 2011 amounted to euro 3,801 million, down euro 245 million from the first half of 2010, or 6.1%, due to a higher share of profit attributable to non-controlling interest (up euro 346 million), higher income taxes (down euro 468 million) with an increased Group’s tax rate (up by approximately two percentage points). Those negatives |  | were partly offset by an improved operating performance (up by 3.2%) mainly in the Exploration & Production Division reflecting higher oil prices, as well as lowered net finance and exchange rate expenses (up euro 224 million) reflecting a positive change in fair value evaluation of certain commodity derivatives which did not meet the formal criteria for hedge accounting.

Eni Interim Consolidated Report / Financial review and other information

In the first half of 2011, special charges of the operating profit included: (i) impairment charges of mineral assets in the Exploration & Production segment (euro 141 million), as certain gas properties in USA were impaired due to negative reserve revisions and a reduced outlook for gas prices, as well as certain capital expenditures incurred in the period made for safety reasons in the Refining & Marketing and Petrochemical Division plants were written off as they related to assets totally impaired in previous reporting periods (euro 108 million); (ii) a risk provision amounting to euro 69 million regarding an antitrust proceeding in the European sector of elastomers |  | following a decision of the European Court of Justice; (iii) negative fair value evaluation of certain commodity derivatives which did not meet the formal criteria for hedge accounting provided by IAS 39 (euro 160 million); (iv) environmental provisions and provisions for redundancy incentives (euro 42 million and euro 34 million, respectively). Special gains of the period mainly related to gains on disposal of marginal assets in the Exploration & Production Division (euro 28 million). Non-operating special items include an adjustment in deferred tax liabilities for the Exploration & Production activities in the United Kingdom (euro 27 million) relating to increased supplementary charges on Continental Shelf properties.

The breakdown of adjusted net profit by Division is shown in the table below:

(a) |  | This item concerned mainly intragroup sales of commodities, services and capital goods recorded in the assets of the purchasing business segment as of end of the period.

In the first half of 2011, the Group adjusted net profit was determined by increased adjusted net profit recorded by Eni’s Divisions: - Exploration & Production (up euro 833 million or 31%) reflecting an improved operating performance (up euro 1,386 million or 21.1%) driven by higher hydrocarbon realizations in dollars (oil up 42.2% and gas up 6.7%) reflecting an improved trading environment, partly offset by the impact associated with a lowered Libyan output and the appreciation of the euro vs. the US dollar (up 5.6%, for an overall impact of approximately euro 270 million); - Engineering & Construction (up euro 66 million or 14%) reflecting an improved operating performance (up euro 88 million or 13.9%) driven by revenue gains and higher profitability of works executed in the onshore and offshore construction businesses; - Petrochemicals reduced adjusted net loss (from euro -66 million to euro -28 million) benefiting from a good operating performance (up euro 28 million or 40%) due to higher product margins, in particular of olefins. These increases were offset in part by the decline in adjusted net profit recorded by the following segments: - Gas & Power (down euro 474 million or 32.1%). The result was |  | negatively affected by a severe contraction in the performance of the Marketing business which suffered a loss of euro 95 million as compared to a profit of euro 665 million in the first half of 2010. The Marketing business was affected by sharply lower gas margins both in Italy and Europe dragged down by strong competitive pressure and oversupply. Also the performance was impacted by sales losses to shippers which import Libyan gas due to unavailability of the raw material, lower seasonal sales and scenario effects as well as lower margins on power generation. The lower results of the Marketing business were partly offset by the better operating performance of the Regulated Businesses in Italy (up by euro 43 million or 4.2%) and the increased result of the International Transport business (up by euro 30 million or 13.8%). The adjusted net profit of the Division does not take into account the possible effect of ongoing renegotiations of long-term contracts which may become effective earlier than the end of June 2011; - Refining & Marketing (down euro 127 million, from euro -49 million in the first half of 2010 to euro -176 million in the first half of 2011) reflecting a weak refining scenario, whose effects were partly offset by continuing optimization and efficiency efforts as well as a steady performance in the marketing business.

In the first half of 2011, Eni’s net sales from operations (euro 53,375 million) increased by euro 5,669 million from the same period of the previous year (or up 11.9%) primarily reflecting higher realizations on oil, products and natural gas in dollar terms. Revenues generated by the Exploration & Production Division (euro 14,252 million) decreased by euro 317 million (or down by 2.2%), due to decreased production in Libya partly offset by higher realizations in dollar terms (oil up 42.2%; natural gas up 6.7%). Eni’s average liquid realizations decreased by 1.50 $/bbl to 101.89 $/bbl due to the settlement of certain commodity derivatives relating to the sale of 4.5 mmbbl in the first half of 2011 (for further details see the disclosure on adjusted net profit of the Exploration & Production Division). Revenues generated by the Gas & Power Division (euro 16,849 million) increased by euro 2,181 million (or 14.9%) mainly due to higher prices |  | and higher volumes sold by consolidated subsidiaries (up 11%). Revenues generated by the Refining & Marketing Division (euro 24,821 million) increased by euro 4,566 million (or up 22.5%) mainly reflecting higher average selling prices in dollars of refined products which were up on average by 30-40% from the first half of 2010 driven by an improved trading environment. Revenues generated by the Petrochemical Division (euro 3,544 million) increased by euro 370 million (up 11.7%) due to an average 27% price increase partly offset by a decline in volumes sold (down 12%, in particular polyethylene). Revenues generated by the Engineering & Construction business (euro 5,705 million) increased by euro 697 million, or 13.9%, from the first half of 2010, as a result of increased activities in the onshore and offshore construction businesses.

Purchases, services and other costs (euro 37,965 million) increased by euro 5,499 million (up 16.9%) due to higher supply costs of purchased oil, gas and petrochemical feedstocks reflecting trends in trading environment. Purchases, services and other costs include special charges for an overall amount of euro 123 million mainly referring to a loss provision of |  | euro 69 million related to an antitrust proceeding in the area of elastomers based on a recent decision of the European Court of Justice described in detail in the paragraph "Guarantees, commitments and risks - Legal proceedings" in the Notes to the interim consolidated financial statements. In the first half of 2010, special charges of euro 97 million regarded environmental and other risk provisions. Payroll and related costs (euro 2,262 million) increased by euro 63 million, or 2.9%, mainly due to higher unit labor cost in Italy

and outside Italy, and the increase in the average number of employees outside Italy (following higher activity levels in the Engineering & Construction business). These increases |  | were partly offset by a reduction in the average number of employees in Italy and lower provision for redundancy incentives.

The increase recorded in the Engineering & Construction business (up euro 47 million) was due to vessels and rigs fleet brought into operation. |  | Impairment charges of euro 257 million mainly regarded impairment of oil&gas assets in the Exploration & Production segment due to downward reserve revisions and a lowered outlook for gas prices, as well as investments made in the period on assets fully impaired in previous reporting periods in the Refining & Marketing and Petrochemical segments (details can be found in the item "Tangible assets" in the Notes to the interim consolidated financial statements).

In the first half of 2011, Eni’s adjusted operating profit amounted to euro 9,102 million, an increase of euro 643 million from the corresponding period of 2010 (up 7.6%). Adjusted operating profit is calculated by excluding an inventory holding profit of euro 909 million and special charges of euro 563 million. The increase was mainly due to an improved operating performance recorded by the following Divisions: - Exploration & Production (up euro 1,386 million, or 21.1%) driven by higher oil and gas realizations (oil up 42.2% and natural gas up 6.7%), partly offset by the impact associated with a lower Libyan output and the appreciation of the euro vs. the US dollar (down approximately euro 270 million); - Engineering & Construction (up euro 88 million or 13.9%) driven by revenue gains and higher profitability of works executed; - Petrochemicals with a 40% improvement in reducing operating loss (up euro 28 million) due to higher product margins, in particular olefins. |  | These increases were partly offset by lower operating profit reported by the: - Gas & Power Division, down euro 687 million, or 36.2%, from the first half of 2010. The main driver of this reduction was a poor lower performance of the Marketing activity (down euro 760 million) as a result of sharply lower gas margins dragged down by strong competitive pressure and oversupply, in addition to sale losses to shippers which import Libyan gas due to unavailability of the raw material, lower seasonal sales as well lower margins on power generation. Adjusted results of the Gas & Power business do not take into account the possible effects of the renegotiation of long-term contracts which may become effective earlier than end of June 2011. These negatives were partly offset by the better operating performance of the Regulated Businesses in Italy and the increased result of the International Transport business; - Refining & Marketing Division with widening adjusted operating losses (down euro 144 million, or 98.6%) driven by a weak refining scenario, whose effects were partially offset by continuing optimization and efficiency efforts as well as a steady performance in the marketing business.

In the first half of 2011, net finance expense decreased by euro 224 million to euro 377 million from the corresponding period of 2010, mainly due to a positive change in the fair value evaluation through profit and loss of certain derivative instruments on exchange rates (from a euro 249 million charge to a euro 192 million |  | income) net of negative exchange differences (down euro 238 million). These instruments did not meet all formal criteria to be designated as hedges under IFRS. Finance charges on finance debt increased reflecting higher interest rates on euro-denominated loans (up 0.4 percentage points the Euribor rate).

Net income from investments
The table below sets forth the breakdown of net income from investments by Division:

|  | 408 |  | 220 |  | 105 |  | 9 |  | (21 | ) |  | 721

In the first half of 2011, net income from investments amounted to euro 721 million and related to: (i) Eni’s share of profit of entities accounted for with the equity method (euro 282 million), mainly in the Gas & Power and Refining & Marketing Divisions; (ii) dividends received by entities accounted for at cost (euro 437 million), mainly |  | relating to Nigeria LNG Ltd. In the first half of 2010, gains on disposal of assets (euro 143 million) were recorded that related to the sale of Eni’s interests in GreenStream (euro 93 million), including the revaluation of the remaining stake and the sale of Eni’s interest in the Belgian company DistriRe SA (euro 47 million).

55.4 |  |  |  | 52.7 |  | 54.5 |  | 1.8 |

In the first half of 2011, income taxes were euro 5,333 million, up euro 468 million, or 9.6%, mainly reflecting higher income taxes currently payable by subsidiaries in the Exploration & Production Division operating outside Italy due to higher taxable profit. Reported tax rate increased by 1.8 percentage points due to certain tax items unrelated to the group profit for the period, namely tax charges on intercompany dividends and a non-deductible special charge on an antitrust proceeding, and the higher taxable profit recorded by subsidiaries in the Exploration & Production Division |  | operating outside Italy, subject to higher tax rate than the statutory Italian tax rate (37.9% for companies operating in the energy industry). Adjusted tax rate, calculated as ratio of income taxes to net profit before taxes on an adjusted basis, was 54.4% (54.9% in the first half of 2010). Non-controlling interest In the first half of 2011, non-controlling interest’s share of profit was euro 658 million and mainly related to Snam Rete Gas SpA (euro 282 million) and Saipem SpA (euro 380 million).

42.2% and natural gas 6.7%), partly offset by the impact associated with a lowered Libyan output and the appreciation of the euro vs. the US dollar (up 5.6%, down approximately euro 270 million). Special charges excluded from the adjusted operating profit of the first half of 2011 amounted to euro 147 million and mainly concerned impairment gas properties in the USA and re-measurement losses recorded on fair value evaluation of the ineffective portion of certain cash flow hedges, partly offset by gains from the divestment of non-strategic assets. Eni’s average oil realizations increased by 42.2% driven by a favorable market environment (Brent crude price increased by 43.9%). |  | In the first half of 2011, Eni’s average liquids realizations decreased by 1.50 $/bbl due to the settlement of certain commodity derivatives relating to the sale of 4.5 mmbbl in the first half of 2011. This was part of a derivative transaction the Company entered into to hedge exposure to variability in future cash flows expected from the sale of a portion of the Company’s proved reserves for an original amount of approximately 125.7 mmbbl in the 2008-2011 period. As of June 30, 2011, the residual amount of that hedging transaction was 4.5 mmbbl. Eni’s average gas realizations increased by 6.7% due to time lags in oil-linked pricing formulae and weak spot prices in some areas, in particular the USA.

business (down euro 760 million). This was partly offset by a better performance of the Regulated businesses in Italy and International transport (overall up euro 73 million). Results of the Marketing business do not take into account the possible effects of the renegotiation of long-term contracts which may become effective earlier than end of June 2011, but is affected by gains on non-hedging commodity derivatives amounting to euro 111 million which could be associated with future sales of gas and electricity, while the first half of 2010 did not take into account of derivative gains amounting to euro 82 million recognized in previous reporting periods, which could be associated with the sale of gas and electricity occurred in the period. As those derivatives did not meet the formal criteria to be designated as hedges under IFRS, the Company was barred from applying hedge accounting and thus gains and losses associated with those derivatives cannot be brought forward to the reporting periods when the associated sales occur. However, in assessing the underlying performance of the Marketing business, management calculates the EBITDA pro-forma adjusted which represents those derivatives as being hedges with associated gains and losses recognized in the reporting period when the relevant sales occur. Management believes that disclosing this measure is helpful in assisting investors to understand these particular business trends (see below). The EBITDA pro-forma adjusted also includes Eni’s share of results of entities which are equity-accounted for statutory reporting purposes and confirms the size of the decline of the business reflecting underlying business trends. Special items excluded from adjusted operating profit amounted to net charges of euro 168 million, mainly relating to negative fair value evaluation of certain commodity derivatives (euro 154 million) in the Marketing business which did not meet the formal criteria for hedge accounting provided by IAS 39. Adjusted net profit for the first half of 2011 was euro 1,002 million, down by euro 474 million from the first half of 2010, or 32.1%. The decline was caused by a lowered operating performance partly offset by higher results reported by costs accounted entities. Marketing In the first half of 2011, the Marketing business reported sharply |  | lower results due to an adjusted operating loss of euro 95 million from a profit of euro 665 million registered in the first half of 2010. Marketing results were negatively impacted by: (i) weaker margins on gas sales registered in Italy and European markets, due to increasing competitive pressures, a prevailing oversupply in the marketplace as well as weak demand trends which negatively impacted selling prices; (ii) lower margins on power generation sales; (iii) reduced sales of Libyan gas to shippers to Italy; (iv) lower seasonal gas sales and unfavorable scenario effects. These negatives trends were partly offset by higher gas sales achieved by consolidated subsidiaries in European target markets and in Italy (overall up by 14.8%). Performance for the first half also included income of euro 51 million recorded on fair value evaluation of certain commodity derivatives the Company entered into to manage economic margins as provided by the new business model of the Marketing activity. Regulated businesses in Italy In the first half of 2011, these businesses reported an adjusted operating profit of euro 1,057 million, up euro 43 million from the corresponding period of 2010, or 4.2%, due to a positive performance in all activities. In particular, despite a decline in transported volumes due to declining demand in Italy, the Transport business increased its operating performance by 1.4% (up euro 9 million) due in particular to the profitability of new investments and efficiency improvement actions. These drivers positively affected also results of the Distribution business (up euro 25 million or 10.6%), also benefiting from increases in tariff components approved by the Authority for Electricity and gas. The Storage business recorded adjusted operating profit of euro 143 million, increasing from the first half of 2010 (euro 134 million). International Transport This business reported an adjusted operating profit of euro 247 million representing an increase of euro 30 million, or 13.8%, from the first half of 2010, mainly due to improved profitability offset in part by the shutdown of the GreenStream pipeline.

impact associated with certain derivatives instruments as detailed below. This performance indicator includes the adjusted EBITDA of Eni’s wholly owned subsidiaries and Eni’s share of adjusted EBITDA generated by certain associates which are accounted for under the equity method for IFRS purposes. Snam Rete Gas’ EBITDA is included according to Eni’s share of equity (55.54% as of June 30, 2011, which takes into account the amount of own shares held in treasury by the subsidiary itself) although this Company is fully consolidated when preparing consolidated financial statements in accordance with IFRS, due to its listed company status. Italgas SpA and Stoccaggi Gas Italia SpA results are also included according to the same share of equity as Snam Rete Gas, due to the restructuring which involved Eni’s regulated business in the Italian gas sector. The parent company Eni SpA, divested the entire share capital of the two subsidiaries to Snam Rete Gas. In order to calculate the EBITDA pro-forma adjusted, the adjusted operating profit of the Marketing business has been modified to take into |  | account the impact of the settlement of certain commodity and exchange rate derivatives that do not meet the formal criteria to be classified as hedges under the IFRS. These are entered into by the Company in respect of certain amounts of gas and electricity that the Company expects to supply at fixed prices during future periods. The impact of those derivatives has been allocated to the EBITDA pro-forma adjusted relating to the reporting periods during which those supplies at fixed prices are recognized. Management believes that the EBITDA pro-forma adjusted is an important alternative measure to assess the performance of Eni’s Gas & Power Division, taking into account evidence that this Division is comparable to European utilities in the gas and power generation sector. This measure is provided in order to assist investors and financial analysts in assessing the Divisional performance of Eni Gas & Power, as compared to its European peers, as EBITDA is widely used as the main performance indicator for utilities. The EBITDA pro-forma adjusted is a non-GAAP measure under IFRS.

(a) |  | Excluding special items.

In the first half of 2011 the Refining & Marketing business reported an adjusted operating loss amounting to euro 290 million, down euro 144 million, or 98.6% from the same period of 2010, driven by sharply lower losses of the refining business. This poor performance reflected continuing unprofitable refining margins due to high costs for oil feedstock which were only partially transferred to product prices pressured by weak demand and oversupply. In addition, performance for the period was hit by rising costs for plant utilities which are indexed to the cost of crude oil, as well as the depreciation of the US dollar vs. euro. Those negatives were mitigated by an improved profitability of Eni’s complex refineries helped by widening price |  | differentials between sweet and sour crudes, higher pricing premiums for gasoline and gasoil compared to fuel oil as well efficiency improvements and optimization of refinery cycles. Marketing activities showed a good performance despite the sudden increases in feedstock prices especially in the first months of the year that could not be fully transferred to final users. Special charges excluded from adjusted operating loss amounted to euro 71 million in the first half of 2011 and mainly related to, impairment of capital expenditures on assets impaired in previous reporting periods, environmental provisions and provisions for redundancy incentives.

NON-GAAP measures
Reconciliation of reported operating profit and
reported net profit to results on an adjusted basis

Management evaluates Group and business performance on the basis of adjusted operating profit and adjusted net profit, which are arrived at by excluding inventory holding gains or losses and special items. Furthermore, finance charges on finance debt, interest income, gains or losses deriving from the evaluation of certain derivative financial instruments at fair value through profit or loss (as they do not meet the formal criteria to be assessed as hedges under IFRS, excluding commodity derivatives), and exchange rate differences are all excluded when determining adjusted net profit of each business segment. The taxation effect of the items excluded from adjusted operating or net profit is determined based on the specific rate of taxes applicable to each of them. The Italian statutory tax rate is applied to finance charges and income (34% is applied to charges recorded by companies in the energy sector, whilst a tax rate of 27.5% is applied to all other companies). Adjusted operating profit and adjusted net profit are non-GAAP financial measures under either IFRS, or US GAAP. Management includes them in order to facilitate a comparison of base business performance across periods and allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models. In addition, management uses segmental adjusted net profit when calculating Return On Average Capital Employed (ROACE) by each business segment. The following is a description of items that are excluded from the calculation of adjusted results. Inventory holding gain or loss is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted average cost method of inventory accounting. Special items include certain significant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non-recurring items under |  | such circumstances; or (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past periods or are likely to occur in future ones. As provided for in Decision No. 15519 of July 27, 2006, of the Italian market regulator (CONSOB), non-recurring material income or charges are to be clearly reported in the management’s discussion and include gains and losses on re-measurement at fair value of certain commodity derivatives, which do not meet formal criteria to the classified as hedges under IFRS, including the ineffective portion of cash flow hedges. Finance charge or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. In addition, gains or losses on the fair value evaluation of the aforementioned derivative financial instruments, excluding commodity derivatives, and exchange rate differences are excluded from the adjusted net profit of business segments. Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment-operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charge pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of the asset retirement obligations in the Exploration & Production Division). Finance charges or interest income and related taxation effects excluded from the adjusted net profit of the business segments are allocated on the aggregate Corporate and financial companies. For a reconciliation of adjusted operating profit and adjusted net profit to reported operating profit and reported net profit see tables below.

Summarized Group Balance Sheet

The summarized group balance sheet aggregates the amount of assets and liabilities derived from the statutory balance sheet in accordance with functional criteria which consider the enterprise conventionally divided into the three fundamental areas focusing on resource investments, operations and financing. Management believes that this summarized group balance sheet is useful information in assisting investors to |  | assess Eni’s capital structure and to analyze its sources of funds and investments in fixed assets and working capital. Management uses the summarized group balance sheet to calculate key ratios such as return on capital employed (ROACE) and the proportion of net borrowings to shareholders’ equity (leverage) intended to evaluate whether Eni’s financing structure is sound and well-balanced.

The appreciation of the euro versus the US dollar as of June 30, 2011 from December 31, 2010 (the EUR/USD exchange rate was 1.445 as of June 30, 2011, as compared to 1.336 as of December 31, 2010, up by 8%) reduced net capital employed, net equity and net borrowings by euro 2,766 million, euro 2,374 million and euro 392 million, respectively, due to exchange rate translation differences. The decrease in net equity coupled with dividend payment were absorbed by net profit for the period and the slight decrease in the level of net borrowings, resulting in the Group leverage to be unchanged at 0.47 as of June 30, 2011 compared to the level as of December 31, 2010. Net capital employed at June 30, 2011 amounted to euro 81,682 million, with a euro 165 million decline from December 31, 2010. |  | Fixed assets amounted to euro 87,118 million, representing a decrease of euro 345 million from December 31, 2010, reflecting negative exchange rate translation differences, partly offset by the positive balance of capital expenditure incurred in the period (euro 6,615 million) and depreciation, depletion, amortization and impairment charges (euro 4,278 million). Net working capital amounted to a negative euro 4,781 million, representing a slight increase of euro 282 million from the closing balance as of December 31, 2010. This was due to increased current and non current other assets and liabilities (up euro 1,106 million) mainly reflecting payment of payables in respect of the Company’s gas suppliers outstanding as of end of 2010 due to the take-or-pay position accrued in 2010 (euro 170 million) and a

higher balance of receivables and payables from joint-venture partners and dividend receivables for entities accounted at cost in the Exploration & Production Division (for a total amount of approximately euro 300 million). This increase was partly offset by higher tax payables and net provisions for deferred tax liabilities accrued in the quarter (down euro 1,069 million). The reduction of trade receivables of euro 1,944 million was absorbed by a similar amount relating to the reduction of trade payables (euro 1,818 million). |  | Net assets held for sale including related liabilities (euro 409 million) mainly related to the following assets: the subsidiary Gas Brasiliano Distribuidora SA which divestment was closed by end of July 2011, the associate TAG GmbH, which is in the final stage of the divestment process as preliminary agreements have already been signed with third parties, and Eni’s subsidiaries and associates engaged in gas transport in Germany and Switzerland for which divestment plans have been progressing in accordance with Eni’s commitments with the European Commission.

Return On Average Capital Employed (ROACE)

Return on Average Capital Employed for the Group, on an adjusted basis is the return on the Group average capital invested, calculated as ratio of net adjusted profit before minority interests, plus net finance charges on net borrowings net of the related tax effect, to net average capital employed. The tax rate applied on finance charges is the Italian statutory tax rate of 34%. The capital invested, as of the period end, used |  | for the calculation of net average capital invested is obtained by deducting inventory gains or losses in the period, net of the related tax effect. ROACE by Division is determined as ratio of adjusted net profit to net average capital invested pertaining to each Division and rectifying the net capital invested as of period-end, from net inventory gains or losses (after applying the Division specific tax rate).

Leverage and net borrowings

Leverage is a measure used by management to assess the Company’s level of indebtedness. It is calculated as a ratio of net borrowings – which is calculated by excluding cash and cash equivalents and certain very liquid assets from financial debt to shareholders’ equity, including minority interest. Management |  | periodically reviews leverage in order to assess the soundness and efficiency of the Group balance sheet in terms of optimal mix between net borrowings and net equity, and to carry out benchmark analysis with industry standards.

Summarized Group cash flow statement and change in net borrowings

Eni’s summarized group cash flow statement derives from the statutory statement of cash flows. It enables investors to understand the link existing between changes in cash and cash equivalents (deriving from the statutory cash flows statement) and in net borrowings (deriving from the summarized cash flow statement) that occurred from the beginning of the period to the end of period. The measure enabling such a link is represented by the free cash flow which is the cash in excess of capital expenditure needs. Starting from free cash flow it is possible to determine either: (i) changes in cash |  | and cash equivalents for the period by adding/deducting cash flows relating to financing debts/receivables (issuance/repayment of debt and receivables related to financing activities), shareholders’ equity (dividends paid, net repurchase of own shares, capital issuance) and the effect of changes in consolidation and of exchange rate differences; (ii) changes in net borrowings for the period by adding/deducting cash flows relating to shareholders’ equity and the effect of changes in consolidation and of exchange rate differences. The free cash flow is a non-GAAP measure of financial performance.

Eni Interim Consolidated Report / Financial review and other information

In the first half of 2011, net cash provided by operating activities amounted to euro 8,596 million. Proceeds from divestments amounted to euro 103 million. Those cash inflows were used to fund cash outflows relating to capital expenditure totaling euro 6,615 million and dividend payments amounting to euro 2,208 million (which included payment of the balance of dividend 2010 to Eni’s shareholders amounting to euro 1,811 million and the remaining amount to minorities, particularly Saipem and Snam Rete Gas) and helped pay down finance debt |  | (down by euro 141 million from December 31, 2010). Cash flow from operating activities of the first half was negatively affected from lower cash inflow of euro 99 million associated with transferring trade receivables due beyond December 31, 2010, to factoring institutions amounting to euro 1,279 million in the fourth quarter of 2010, while the current half benefited from transferring euro 1,180 million of trade receivables due beyond June 30, 2011, to same institutions.

Risk factors and uncertainties

Foreword The main risks that the Company is facing and actively monitoring and managing are: (i) the market risk deriving from exposure to fluctuations in interest rates, foreign currency exchange rates and commodity prices; (ii) the credit risk deriving from the possible default of a counterparty; (iii) the liquidity risk deriving from the risk that suitable sources of funding for the Group’s operations may not be available; (iv) the Country risk in the upstream business; (v) the operational risk; (vi) risks associated with the current trends in the gas market and the possible evolution of regulations in the Italian gas market; (vii) the specific risks deriving from exploration and production activities. Financial risks are managed in respect of guidelines defined by the parent company, targeting to align and coordinate Group companies’ policies on financial risks ("Eni Guidelines on Management and Control of Financial Risks"). In the course of 2011, the Company has been implementing its new pricing and risk management strategies for actively managing economic margins, particularly with regard to the Gas & Power division due to a radically-changed competitive environment (see "Risks and uncertainties associated with the competitive environment in the European natural gas market" below). Market risk Market risk is the possibility that changes in currency exchange rates, interest rates or commodity prices will adversely affect the value of the Group’s financial assets, liabilities or expected future cash flows. The Company actively manages market risk in accordance with a set of policies and guidelines that provide a centralized model of handling finance, treasury and risk management operations based on the Company’s departments of operational finance: the parent company’s (Eni SpA) finance department, Eni Coordination Center, Eni Finance USA and Banque Eni, which is subject to certain bank regulatory restrictions preventing the Group’s exposure to concentrations of credit risk, and Eni Trading & Shipping, that is in charge to execute certain activities relating to commodity derivatives. In particular, Eni SpA and Eni Coordination Center manage subsidiaries’ financing requirements in and outside Italy, respectively, covering funding requirements and using available surpluses. All transactions concerning currencies and derivative financial contracts are managed by the parent company as well as the activity of negotiating emission trading certificates. The commodity risk is managed by each business unit with Eni Trading & Shipping executing the negotiation of hedging derivatives. Eni uses derivative financial instruments (derivatives) in order to minimize exposure to market risks related to changes in exchange |  | rates and interest rates and to manage exposure to commodity prices fluctuations. Eni does not enter into derivative transactions on interest rates or exchange rates on a speculative basis. Commodity derivatives are entered into with the aim of: a) hedging certain underlying commodity prices set in contractual arrangements with third parties. Hedging derivatives can be entered also to hedge highly probable future transactions; b) effectively managing the economic margin (positioning). It consists in entering purchase/sale commodity contracts in both commodity and financial markets aiming at altering the risk profile associated to a portfolio of physical assets of each business unit in order to improve margins associated to those assets in case of favorable trends in the commodity pricing environment; c) arbitrage. It consists in entering purchase/sale commodity contracts in both commodity and financial markets, targeting the possibility to earn a profit (or reducing the logistical costs associated to owned assets) leveraging on price differences in the marketplace; d) proprietary trading. It consists in entering purchase/sale commodity contracts in both commodity and financial markets, targeting to earn an uncertain profit, should certain expectations fulfill about a favorable trend in the commodity pricing environment. The framework defined by Eni’s policies and guidelines prescribes that measurement and control of market risk be performed on the basis of maximum tolerable levels of risk exposure defined in terms of limits of stop loss, which expresses the maximum tolerable amount of losses associated with a certain portfolio of assets over a pre-defined time horizon, or in accordance with value-at-risk techniques. Those techniques make a statistical assessment of the market risk on the Group’s activity, i.e., potential gain or loss in fair values, due to changes in market conditions taking account of the correlation existing among changes in fair value of existing instruments. Eni’s finance departments define maximum tolerable levels of risk exposure to changes in interest rates and foreign currency exchange rates in terms of value-at-risk, pooling Group companies risk positions. Eni’s calculation and measurement techniques for interest rate and foreign currency exchange rate risks are in accordance with established banking standards, as established by the Basel Committee for bank activities surveillance. Tolerable levels of risk are based on a conservative approach, considering the industrial nature of the company. Eni’s guidelines prescribe that Eni Group companies minimize such kinds of market risks by transferring risk exposure to the parent company finance department. With regard to the commodity risk, Eni’s policies and guidelines define rules to manage this risk aiming at optimizing core activities

and pursuing preset targets of margin stability and performance. The maximum tolerable level of risk exposure is defined in terms of value-at-risk and stop loss in connection with exposure deriving from commercial activities as well as exposure deriving from proprietary trading executed by the subsidiary Eni Trading & Shipping. Internal mandates to manage the commodity risk provide for a mechanism of allocation of the Group maximum tolerable risk level to each business unit within this framework, Eni Trading & Shipping, in addition to managing risk exposure associated with its own commercial activity ad proprietary trading, pools Group companies requests for negotiating commodity derivatives, ensuring execution services to Group companies. The strategic risk is the economic risk which is intrinsic to each business unit. Exposure to that kind of risk does not undergo any systematic hedging or managing activities due to a strategic decision made by the Company, except for extraordinary business or market conditions. Therefore, internal risk policies and guideline do not foresee any mandate to manage, or any maximum tolerable level of risk exposure. To date, exposure to the strategic risk is associated with plans for commercial development of proved and unproved oil and gas reserves, long-term gas supply contracts for the portion not balanced by in-place or highly probable sale contracts, refining margins and minimum compulsory stock. Any hedging activity of the strategic risk is the sole responsibility of Eni’s top management, due to the extraordinary conditions that may lead to such a decision. This kind of transaction is not subject to specific risk limits due to nature; however it is subject to monitoring and assessment activities. The three different market risks, whose management and control have been summarized above, are described below. Exchange rate risk Exchange rate risk derives from the fact that Eni’s operations are conducted in currencies other than the euro (mainly the US dollar). Revenues and expenses denominated in foreign currencies may be significantly affected by exchange rates fluctuations due to conversion differences on single transactions arising from the time lag existing between execution and definition of relevant contractual terms (economic risk) and conversion of foreign currency-denominated trade and financing payables and receivables (transactional risk). Exchange rate fluctuations affect the Group’s reported results and net equity as financial statements of subsidiaries denominated in currencies other than the euro are translated from their functional currency into euro. Generally, an appreciation of the US dollar versus the euro has a positive impact on Eni’s results of operations, and vice-versa. Eni’s foreign exchange risk management policy is to minimize economic and transactional exposures arising from foreign currency movements. Eni does not undertake any hedging activity for risks deriving from the translation of foreign currency denominated profits or assets and liabilities of subsidiaries which prepare financial statements in a currency other than the euro, except for single transactions to be evaluated on a case-by-case basis. Effective management of exchange rate risk is performed within Eni’s central finance departments which pools Group companies positions, hedging the Group net exposure through the use of certain derivatives, such as currency swaps, forwards and options. Such derivatives are |  | evaluated at fair value on the basis of market prices provided by specialized info-providers. Changes in fair value of those derivatives are normally recognized through profit and loss as they do not meet the formal criteria to be recognized as hedges in accordance with IAS 39. The VaR techniques are based on variance/covariance simulation models and are used to monitor the risk exposure arising from possible future changes in market values over a 24-hour period within a 99% confidence level and a 20-day holding period. Interest rate risk Changes in interest rates affect the market value of financial assets and liabilities of the company and the level of finance charges. Eni’s interest rate risk management policy is to minimize risk with the aim to achieve financial structure objectives defined and approved in the management’s finance plans. Borrowing requirements of Group companies are pooled by the Group’s central finance department in order to manage net positions and the funding of portfolio developments consistently with management’s plans while maintaining a level of risk exposure within prescribed limits. Eni enters into interest rate derivative transactions, in particular interest rate swaps, to effectively manage the balance between fixed and floating rate debt. Such derivatives are evaluated at fair value on the basis of market prices provided from specialized sources. Changes in fair value of those derivatives are normally recognized through the profit and loss account as they do not meet the formal criteria to be accounted for under the hedge accounting method in accordance with IAS 39. Value at risk deriving from interest rate exposure is measured daily on the basis of a variance/covariance model, with a 99% confidence level and a 20-day holding period. Commodity risk Eni’s results of operations are affected by changes in the prices of commodities. A decrease in oil and gas prices generally has a negative impact on Eni’s results of operations and vice-versa. Eni manages exposure to commodity price risk arising in normal trading and commercial activities in view of achieving stable margins. In order to accomplish this, Eni uses derivatives traded on the organized markets of ICE and NYMEX (futures) and derivatives traded over the counter (swaps, forward, contracts for differences and options) with the underlying commodities being crude oil, refined products or electricity. Such derivatives are evaluated at fair value on the basis of market prices provided from specialized sources or, absent market prices, on the basis of estimates provided by brokers or suitable evaluation techniques. Changes in fair value of those derivatives are normally recognized through the profit and loss account as they do not meet the formal criteria to be recognized as hedges in accordance with IAS 39. Value at risk deriving from commodity exposure is measured daily on the basis of a historical simulation technique, with a 95% confidence level and a one-day holding period. The following table shows amounts in terms of value at risk, recorded in the first half of 2011 (compared with full year 2010) relating to interest rate and exchange rate risks in the first section, and commodity risk in the second section. VaR values are stated in US dollars, the currency most widely used in oil products markets.

Credit risk Credit risk is the potential exposure of the Group to losses in case counterparties fail to perform or pay amounts due. The Group manages differently credit risk depending on whether credit risk arises from exposure to financial counterparties or to customers relating to outstanding receivables. Individual business units and Eni’s corporate financial units and Eniadfin are responsible for managing credit risk arising in the normal course of the business. The Group has established formal credit systems and processes to ensure that before trading with a new counterpart can start, its creditworthiness is assessed. Also credit litigation and receivable collection activities are assessed. Eni’s corporate units define directions and methods for quantifying and controlling customer’s reliability. With regard to risk arising from financial counterparties, Eni has established guidelines prior to entering into cash management and derivative contracts to assess the counterparty’s financial soundness and rating in view of optimizing the risk profile of financial activities while pursuing operational targets. Maximum limits of risk exposure are set in terms of maximum amounts of credit exposures for categories of counterparties as defined by the Company’s Board of Directors taking into account the credit ratings provided by primary credit rating agencies on the marketplace. Credit risk arising from financial counterparties is managed by the Group central finance departments, including Eni’s subsidiary Eni Trading & Shipping which specifically engages in commodity derivatives transactions and by Group companies and Divisions, only in the case of physical transactions with financial counterparties consistently with the Group centralized finance model. Eligible financial counterparties are closely monitored to check exposures against limits assigned to each counterparty on a daily basis. Exceptional market conditions have forced the Group to adopt contingency plans and under certain circumstances to suspend eligibility to be a Group financial counterparty. Actions implemented also have been intended to limit concentrations of credit risk by maximizing counterparty diversification and turnover. Counterparties have also been selected on more stringent criteria, particularly in |  | transactions on derivatives instruments and with maturity longer than a three-month period. Liquidity risk Liquidity risk is the risk that suitable sources of funding for the Group may not be available, or the Group is unable to sell its assets on the marketplace in order to meet short-term finance requirements and to settle obligations. Such a situation would negatively impact Group results as it would result in the Company incurring higher borrowing expenses to meet its obligations or under the worst of conditions the inability of the Company to continue as a going concern. As part of its financial planning process, Eni manages the liquidity risk by targeting such a capital structure as to allow the Company to maintain a level of liquidity adequate to the Group’s needs, optimizing the opportunity cost of maintaining liquidity reserves also achieving an efficient balance in terms of maturity and composition of finance debt. The Group capital structure is set according to the Company’s industrial targets and within the limits established by the Company’s Board of Directors who are responsible for prescribing the maximum ratio of debt to total equity and minimum ratio of medium and long-term debt to total debt as well as fixed rate medium and long-term debt to total medium and long-term debt. In spite of ongoing tough credit market conditions resulting in higher spreads to borrowers, the Company has succeeded in maintaining access to a wide range of funding at competitive rates through the capital markets and banks. The actions implemented have enabled the Group to maintain access to the credit market particularly via the issue of commercial paper also targeting to increase the flexibility of funding facilities. The above-mentioned actions aimed at ensuring availability of suitable sources of funding to fulfill short-term commitments and due obligations also preserving the necessary financial flexibility to support the Group’s development plans. In doing so, the Group has pursued an efficient balance of finance debt in terms of maturity and composition leveraging on the structure of its lines of credit, particularly the committed ones. At present, the

Group believes it has access to sufficient funding and has also both committed and uncommitted borrowing facilities to meet currently foreseeable borrowing requirements. As of June 30, 2011, Eni maintained short-term committed and uncommitted unused borrowing facilities of euro 13,162 million, of which euro 4,141 million were committed, and long-term committed unused borrowing facilities of euro 1,501 million. These facilities bore interest rates that reflected prevailing market conditions. Fees charged for unused facilities were immaterial. Eni has in place a program for the issuance of Euro Medium Term Notes up to euro 15 billion, of which about euro 10,393 million were drawn as of June 30, 2011. |  | The Group has credit ratings of A+ and A-1 respectively for long and short-term debt assigned by Standard & Poor’s, outlook stable. The credit rating assigned by Moody’s is Aa3 and P-1, respectively for long and short-term debt. The long-term rate assigned by Moody’s has been placed on review for possible downgrade. The tables below summarize the Group main contractual obligations (undiscounted) for finance debt repayments, including expected payments for interest charges, and trade and other payables maturities outstanding at year end.

The Group has in place a number of contractual obligations arising in the normal course of the business. To meet these commitments, the Group will have to make payments to third parties. The Company’s main obligations pertain to take-or-pay clauses contained in the Company’s gas supply contracts or shipping arrangements, whereby the Company obligations consist of off-taking minimum quantities of product or service or, in case of failure, paying the |  | corresponding cash amount that entitles the Company the right to off-take the product or the service in future years. Future obligations in connection with these contracts were calculated by applying the forecasted prices of energy or services included in the four-year business plan approved by the Company’s Board of Directors.

Country risk Substantial portions of Eni’s hydrocarbons reserves are located in Countries outside the EU and North America, certain of which may be politically or economically less stable than EU or North America. At December 31, 2010, approximately 80% of Eni’s proved hydrocarbons reserves were located in such Countries. Similarly, a substantial portion of Eni’s natural gas supplies comes from Countries outside the EU and North America. In 2010, approximately 60% of Eni’s domestic supply of natural gas came from such Countries. Developments in the political framework, economic crisis, social unrest can compromise temporarily or permanently Eni’s ability to operate or to economically operate in such Countries, and to have access to oil and gas reserves, as proved by recent events in North Africa, where Eni was forced to halt productions at a number of oil and gas fields in Libya and shut down the GreenStream import pipeline. Further risks associated with activities in those Countries are represented by: (i) lack of well-established and reliable legal systems and uncertainties surrounding |  | enforcement of contractual rights; (ii) unfavorable developments in laws and regulations leading to expropriation of Eni’s titles and mineral assets, changes in unilateral contractual clauses reducing the value of Eni’s assets; (iii) restrictions on exploration, production, imports and exports; (iv) tax or royalty increases; (v) civil and social unrest leading to sabotages, acts of violence and incidents. While the occurrence of these events is unpredictable, it is possible that they can have a material adverse impact on Eni’s financial condition and results of operations. Eni periodically monitors political, social and economic risks of approximately 60 Countries where it has invested, or, with regard to upstream projects evaluation, where Eni is planning to invest in order to assess returns of single projects based also on the evaluation of each Country’s risk profile. Country risk is mitigated in accordance with guidelines on risk management defined in the procedure "Project risk assessment and management". In the most recent years, unfavorable developments in the regulatory framework, mainly regarding tax issues, have been implemented or announced also in EU Countries and in North America.

Eni Interim Consolidated Report / Financial review and other information

In recent months, several North African and Middle Eastern oil producing Countries have experienced and continue to experience an extreme level of political instability that has resulted in changes in governments, unrest and violence and consequential economic disruptions. As of end of 2010, approximately 30% of the Company’s proved oil&gas reserves was located in North Africa. Further material changes are likely but largely unpredictable. Such instability is affecting, in particular, Libya. In 2010, approximately 15% of Eni’s production originated from Libya and a material amount of Eni’s proved reserves were located in Libya. Due to the outbreak of political unrest and conflict in the Country, all of Eni’s producing facilities came to a halt including export through the GreenStream gas pipeline, with the sole exception of the Wafa field where it is supporting local production of electricity. Plants and pipelines were put into safety status and no damage has been reported. Eni is technically able to resume the gas output at a level similar to the pre-crisis flows once the situation has returned to normal. Since March 2011 Eni has evacuated all the personnel and suspended ongoing exploration and development activities. Eni’s production in Libya is currently flowing at a rate of 50 kboe/d, down from the expected level of 280 kboe/d for the year. Assuming the actual production level in Libya for the remainder of 2011, management forecasts a 10 percentage points reduction in the expected Company’s production plateau for the full year at a constant pricing scenario compared to the production level achieved in 2010. As of June 30, 2011, Eni’s net capital employed in Libya amounted to $2.04 billion ($2.5 billion as of December 31, 2010), including a 50% interest in GreenStream BV. An impairment review was performed on Eni’s properties in Libya and management concluded that there was no need for impairment charges also factoring in the assessment a period of disruption much longer than management’s internal forecast. Due to the ongoing conflict and the limitations deriving from the requirement for Eni to comply with international sanctions against Libya, Eni formally notified the Libyan counterparty the occurrence of force majeure events in April 2011. Under such circumstances, the parties are discussing the necessary actions to mitigate the consequences of force majeure, as required by contractual arrangements currently in force between Eni and its Libyan counterparty. Should the parties fail to agree upon mitigation actions and should force majeure last more than two years from notification, the petroleum contracts between Eni and its Libyan partner will terminate unless otherwise agreed. Eni has been pursuing and will continue to pursue all necessary and possible steps to safeguard its investments in Libya. Operational risk Eni’s business activities are subject to a broad range of laws and regulations in force in Countries in which it operates, specific rules concerning oil and gas activities as well as acquisition of a license before exploratory drilling may commence. The Company has incurred and will continue incurring in the future substantial amounts of expenses to comply with applicable regulations in the matter of HSE. In addition, the Company may incur environmental liabilities as a result of past or future contaminations and the associated needs to clean-up and restore |  | polluted areas. Breach of Environmental, Health and Safety laws exposes employees to criminal and civil liabilities and in the case of violation of certain rules regarding safety on the workplace also companies can be liable as provided for by a general EU rule on businesses liability due to negligent or willful conduct on part of their employees as adopted in Italy with Law Decree No. 231/2001. Implementing the provisions of the Community Law of 2009 (Article No. 19 of June 4, 2010, No. 96) in 2011 was extended the civil responsibility related to the environmental matter crimes. In 2010, as concerns the protection of health and safety in the workplace, there were not significant updates of the Italian relevant legislation. In Europe, the Parliament started the revision of the Seveso Directive, with the main objective to align the documentation of the Seveso II directive to the CLP regulation (Classification Labelling and Packaging of dangerous substances and mixtures). Environmental laws impose restrictions on the types, quantities and concentration of various substances that can be released into the environment and on discharges to surface and subsurface water. In 2010, the procedure for approval of the IED directive (Industrial Emissions Directive) on industrial emission (Directive 75/2010) was terminated. The adoption of the IED directive will have a significant impact on the IPPC installation, in particular on the older Eni plants. Last year, the new system for the traceability and discharge of waste (SISTRI) adopted in 2009 produced relevant impact on Eni’s operations and organization. The new system aims at real time monitoring the route of waste from production up to its disposal/recycling, also prosecuting any unlawful act. The SISTRI system will be fully operational by September 2011, and will substitute all paper documents on waste management as these items will all be available to relevant authorities in real time. Eni also upholds various voluntary initiatives to implement industrial best practices. As part of the Carbon Disclosure Project involving management of water resources, Eni endorsed the CDP Water Disclosure initiative for the year 2010. That initiative aimed at assessing strategies, management plans and governance of major world companies for a sustainable use of water. Industrial sites located in stressed areas and the related risks have also been included in the disclosure reported to the Dow Jones Sustainability Index. As concerns the habitat, the respect of biodiversity and the protection of biosystem services are crucial requirements when exploring for, drilling and producing oil and gas. In Italy, the concept of protection of biodiversity has been stressed in the National Strategy on Biodiversity, in force from October 2010, which acts as a tool for integrating biodiversity in national policies, stressing the need for maintaining and protecting its conservation and sustainable use. Eni has adopted HSE guidelines, a Model of Management System and new policies (issued on April 2011) for protecting Eni’s employees, the populations involved in its activity, contractors and clients, and the environment and being in compliance with local and international rules and regulations. Eni’s guidelines prescribe the adoption of international best practices in setting internal principles, standards and solutions.

Eni Interim Consolidated Report / Financial review and other information

The ongoing process for identifying, evaluating and managing HSE operations in each phase of the business activity is performed through the adoption of procedures and effective pollution management systems tailored to the peculiarities of each business and industrial site and on steady enhancement of plants and process. The integrated management system of health, safety and environmental matters is supported by the adoption of Eni’s Model of HSE operations in all the Divisions and companies of the Eni Group. This is a procedure based on an annual cycle of planning, implementation, control, review of results and definition of new objectives. The model is directed towards the prevention of risks, the systematic monitoring and control of HSE performance, in a continuous improvement cycle. Eni is targeting to achieve total certification of its plants (in particular OHSAS 18001 and ISO 140001). The plan for the completion of the site with significant HSE risk certification is expected to be concluded within 2013. The system for monitoring HSE risks is based on the monitoring of HSE indicators at quarterly, semi-annual and annual intervals and on an audit plan performed on all the industrial sites consisting of: - technical audits aimed at verifying the existence of adequate management systems, their proper application, adequacy, consistency and compliance with Eni’s HSE management model, Ethical Code and Model 231; - audits for the confirmation/renewal of certification performed annually by external certifying entities; - control of compliance with existing HSE regulations; - specific audits on relevant issues (e.g. following events/accidents/reported failures). Coding activities and procedures on operating phases allow reducing the human component in the plant risk management. Accidents which occurred in the past few years in the industry drive Eni to pay greater attention to process safety and asset integrity, also by means of activities aimed at increasing the awareness of middle management and a widespread dissemination of assessment tools and process audit plans. Operating emergencies that may have an adverse impact on assets, people and the environment are managed by the business units at each industrial site. Those units manage the HSE risk in a systematic way that involves having emergency response plans in place with a number of corrective actions to be taken that might possibly minimize any damage to people or the environment in the event of an incident. In the case of extraordinary events, Divisions/entities are assisted by the Eni Unit of Crisis to deal with the emergency through a team which has the necessary training and skills to coordinate in a timely and efficient manner resources and facilities. In addition to the Company’s system for monitoring, managing and responding to HSE risks and issues which has been adopted by all Group subsidiaries, Eni has entered into insurance arrangements through its shareholding in the OIL insurance Ltd and with other insurance partners in order to limit possible economic impacts associated with damages to both third parties and the environment occurring in case of both onshore and offshore incidents. Covered liabilities vary depending on nature and type of |  | circumstances; however underlying amounts represent significant shares of the plafond granted by insuring companies. In particular, in the case of oil spills and other environmental damage, current insurance policies cover costs of cleaning-up and remediating polluted sites, damage to third parties and containment of physical damage up to $1.1 billion for offshore events and $1.5 billion for onshore plants (refineries). These are complemented by insurance policies that cover owners, operators and renters of vessels with the following maximum amounts: $1 billion for the fleet owned by the subsidiary LNG Shipping in the Gas & Power segment and FPSOs used by the Exploration & Production segment for developing offshore fields; $500 million for time charters. Following the incident at the Macondo well in the Gulf of Mexico the US Government and other governments have adopted or are likely to adopt more stringent regulations targeting safety and reliable oil and gas operations in the US and elsewhere, particularly relating to environmental and health and safety protection controls and oversight of drilling operations, as well as access to new production areas. Italian authorities have passed legislation with Law Decree No. 128 on June 29, 2010, that would introduce certain restrictions to activities for exploring and producing hydrocarbons; however titles for conducting oil and gas operation would not be affected by that. Eni and other operators in the industry have commenced discussions with the Italian Ministry for Economic Development and the Ministry for the Environment to clarify uncertainties in correctly interpreting and applying the new regulations. After the above-mentioned discussions, some additional prescriptions were adopted allowing the operators to perform hydrocarbon extraction even in the presence of a number of restrictions (such as adoption of black boxes on certain drilling rigs and "well control" mandatory certifications for drilling personnel). On October 7, 2010, the European Parliament approved a resolution on this issue and rejected a proposed moratorium on new oil platforms until global adoption of uniformly more stringent environmental protection laws. Consequently, in the March 16, 2011-May 11, 2011 period the European Commission performed the Public consultation titled "Improving offshore safety in Europe". Consequently, the interested parties, including operators, were requested to express an evaluation on the applicable existing legislation referred to the offshore platforms. Adoption of stricter regulation both at national and European or international level and expected evolution in industrial practices could trigger cost increases to comply with new HSE standards which the Company might adopt either on a mandatory or voluntary basis. Also our exploration and development plans to produce hydrocarbons reserves and drilling programs could be affected by changing HSE regulations and industrial practices. Lastly, the Company expects that production royalties and income taxes in the oil&gas industry will likely trend higher than in previous years. At the beginning of 2011, drilling activities in the Gulf of Mexico restarted after the end of the moratorium period following Macondo accident. Activities of the year could slow down as a result of the more rigid authorization process for the permits concessions. In order to achieve the highest security standards of our

operations in the Gulf of Mexico, Eni entered a consortium led by Helix that worked at the containment of the oil spill at the Macondo well. The Helix Fast Response System (HFRS) performs certain activities associated with underwater containment of erupting wells, evacuation of hydrocarbon on the sea surface, storage and transport to the coastline. Risks and uncertainties associated with the competitive environment in the European natural gas market Management expects that conditions will remain unfavorable in the gas competitive environment in Europe over the next few years due to current oversupply on the marketplace, weak demand and high competitive pressure. Management forecasts that the gas market will remain depressed until 2012 under a best case scenario. Those trends will negatively affect profitability of Eni’s Marketing activity that reported adjusted operating losses of euro 95 million in the first half of 2011 compared to operating profit of euro 665 million reported in the first half of 2010. In the three-year period 2007-2009 under normal business condition, the Gas & Power Marketing activity contributed approximately 10% of the Group consolidated adjusted operating profit. The Company forecasts that the gas market will find a better balance in the medium/long-term supported by secular growth trends in gas demand driven by economic development and the higher environmental compatibility of gas over other fossil fuels in the production of electricity through the CCGT technology. The ongoing changes in the energetic policies of the Euro-zone as a result of the nuclear accident at the Fukushima plant in Japan could accelerate recovery in gas consumption. In addition, the fiscal policies of the Member states could affect the composition of the energetic mix through the introduction of penalties on the use of the most inefficient and dirtiest sources in energy production. Examples of these trends are a proposal for an European directive to enact a carbon tax to be levied on those sectors which do not participate the ETS mechanism as well as a proposal in the UK to enact certain fiscal adjustments to put a floor at the price of carbon dioxide emissions. The impact of above-mentioned measures on the competitiveness of gas in relation to other energy sources will however depend on the specific conditions of each market. Those dynamics will be partly absorbed by the increasing use of renewable sources in the meeting of energy requirements. Looking forward and taking into account the above-mentioned trends, management estimates that long-term demand growth will achieve an annual average rate of 1.7% and 1% in Italy and Europe respectively, until 2020. Over the short-term, management forecasts a soft patch as a result of uncertainties in the economic recovery and, particularly in Italy, a weak situation in the power generation segment. Gas availability remains abundant as large investments to upgrade import pipelines to Europe have come online from Russia, Algeria and Libya in recent years and large availability of LNG on a worldwide scale has found an outlet at the European continental hubs driving the development of very liquid spot gas markets. The latter was driven by the ramp-up of important upstream projects which added an approximate 65 bcm of liquefaction capacity in the three-year period 2008-2010, coupled with commercial development |  | of non-conventional gas resources in the United States which have reduced the Country’s dependence on LNG imports. Furthermore, in the near future it is expected the start-up of new infrastructures in various European entry points which will add approximately 50-60 bcm of new import capacity (particularly the Medgaz pipeline connecting Algeria to the Iberian Peninsula, the Nord Stream pipeline connecting Russia to Germany through the Baltic Sea as well as new LNG facilities) and further 27 bcm with the second line of the Nord Stream later. Also counter flow expenditures will favor exchanges among European Countries. The pressure on the offer side will be partly offset by the progressive decline of the domestic production in the European area; the probable postponement of new projects for the development of gas reserves by upstream operators; the increase of power demand in Asia also owing to the expected replacement of nuclear production with gas-fired power facilities in Japan; the uncertainties on the resumption of gas exportation through the GreenStream pipeline from Libya. Ongoing imbalances between demand and supply, increasing competitive pressures and higher liquidity at the continental hubs have pressured Eni’s profitability on gas sales in Europe as prices at European hubs, which have become the prevailing reference price for sales arrangements in Europe, have fallen below the oil-linked cost of gas supplies which is provided by the Company’s long-term purchase contracts (de-coupling). Management expects that the de-coupling will continue affecting gas unit margin over the remainder of the year and in 2012 at least. In Italy ongoing competitive pressures have eroded the Company’s unit margins and the market share. Management expects that gas margins will remain weak in Italy over the remainder of 2011 and the next couple of years, while trends in the loss of market share have reversed in the first half of 2011 as the Company has regained share in the majority of its market segments due to a good volume performance (up by 11.4% compared to the first half of 2010). Those negative trends are expected to influence returns and cash flow of the Company’s Marketing activity for the remainder of 2011 and in 2012, while the recovery will materialize in 2013 for the Italian activity. Also future results will be affected by the Company having to deal with the financial obligations deriving from its take-or-pay, long-term gas supply contracts (see next risk factor). Eni has been implementing initiatives to counteract the negative effects of the depressed marketplace. Management intends to renegotiate better economic terms within the Company’s long-term gas purchase contracts, so as to restore the competitiveness of the Company’s cost position in the current difficult market environment. The renegotiation of revised contractual terms, including any price revisions and contractual flexibility, is established by such contractual clauses whereby parties are held to bring the contract back to the economic equilibrium in case of significant changes in the market environment, like the ones that have been occurring from the second half of 2008. Negotiations are ongoing with all the Company’s main gas suppliers. In addition to contract renegotiation, management is pursuing the initiatives which are described below: - maximizing gas sales volumes leveraging on the multiple presence in a number of markets, market knowledge, consolidating market leadership in Europe and marketing policies

aimed at increasing Eni’s market share in Europe; - regaining market share in the Italian market and preserving marketing margins leveraging on the commercial strength and capabilities of the Company, selecting the customer portfolio and implementing marketing actions to retain clients by proposing new pricing offers and schemes and improving service quality; - reducing the cost-to-serve, marketing and general and business support expenses; - monitoring and effectively managing working capital requirements. In addition, the Company has fully adopted a new pricing and risk management strategy whereby the Company intends to more effectively manage the economic margins and optimize the value of assets (gas supply contracts, customer base, and market position). Actions that will be implemented or have been implemented as of recently include: (i) ensuring the balance between supply and sale programs over periods of up to four years and monthly schedules of needs and physical flows; (ii) effectively managing flexibilities associated with the portfolio of long-term gas supply contracts and other assets available to the Company in the gas value chain, also leveraging on entering arbitrage contracts so as to unlock value from the Company’s access to storage capacities and transport rights and other assets; (iii) effectively managing the commodity risk and the volume risk leveraging on entering market position in order to capture possible favorable trends in market prices, within limits set by internal policies and guidelines that define the maximum tolerable level of market risk. Taking into account the Company’s expectations about future developments in the gas scenario and ongoing industrial initiatives, management updated results and associated cash flow projections for the two CGUs which are comprised in the Company’s gas Marketing business (the European CGU and the Italian CGU). The updated values in use of both CGUs were in line with the financial projections of the 2010 Annual Report, thus confirming recoverability of the carrying amounts of the assets of the above-mentioned CGUs. Projections of future results and cash flows have been made considering the economic and financial effects of renegotiating the main Eni gas long-term supply contracts. There is no assurance about the final outcome of planned renegotiations. Should the outcome fall short of management’s expectations and absent a solid recovery in the gas market, management believes that such a development could negatively affect the Company’s future returns and cash flows in its gas business with further possible consequences on the recoverability of the carrying amounts of the asset of the two CGU. Current negative trends in the gas scenario may impair the Company’s ability to fulfill its minimum off-take obligations in connection with its take-or-pay, long-term gas supply contracts In order to secure long-term access to gas availability, particularly with a view of supplying the Italian gas market, Eni has signed a number of long-term gas supply contracts with key producing Countries that supply the European gas markets. These contracts have been ensuring approximately 80 bcm of gas availability from 2010 (including the Distrigas portfolio of supplies and excluding |  | Eni’s subsidiaries and affiliates gas supply) with a residual life of approximately 18 years and a pricing mechanism indexed to the price of crude oil and its derivatives (gasoil, fuel oil, etc). The contracts provide take-or-pay clauses whereby the Company is required to collect minimum pre-determined volumes of gas in each year of the contractual term or, in case of failure, to pay the whole price, or a fraction of that price, applied to uncollected volumes up to the minimum contractual quantity. The take-or-pay clause entitles the Company to collect pre-paid volumes of gas in later years during the period of contract execution. Amounts of cash pre-payments and time schedules for collecting pre-paid gas vary from contract to contract. Generally speaking, cash pre-payments are calculated on the basis of the energy prices current in the year of non-fulfillment with the balance due in the year when the gas is actually collected. Amounts of pre-payments range from 10 to 100 percent of the full price. The right to collect pre-paid gas expires within a ten-year term in some contracts or remains in place until contract expiration in other arrangements. In addition, rights to collect pre-paid gas in future years can be exercised provided that the Company has fulfilled its minimum take obligation in a given year and within the limit of the maximum annual quantity that can be collected in each contractual year. In this case, Eni will pay the residual price calculating it as the percentage that complements 100%, based on the arithmetical average of monthly base prices current in the year of the off-take. Similar considerations apply to ship-or-pay contractual obligations. In case Eni fails to off-take the contractual minimum amounts, it will be exposed to a price risk, because the purchase price Eni will ultimately be required to pay is based on prices prevailing after the date on which the off-take obligation arose. In addition, Eni is subject to the risk of not being able to dispose of pre-paid volumes. Management believes that the current outlook for tepid gas demand growth and large gas availability on the marketplace, the possible evolution of sector-specific regulation, as well as the de-coupling between trends in gas prices indexed to oil vs. gas benchmark prices at spot markets, represent risk factors to the Company’s ability to fulfill its minimum take obligations associated with its long-term supply contracts. Up to date, Eni incurred the take-or-pay clause as the Company collected lower volumes than its minimum take obligations in each of those years accumulating deferred costs for an amount of euro 1.71 billion and paying the associated cash advances. The carrying amounts of those pre-paid volumes of gas correspond to the cost incurred which is lower than the net realizable value as of June 30, 2011. Considering ongoing market trends and the Company’s outlook for its sales volumes for the full year 2011 seen improving over 2010 (see the "Outlook" section below), management believes that it is likely that in 2011 Eni will fail to fulfill its minimum take obligations provided by contractual terms thus triggering the take-or-pay clause for significant volumes, although the size of the issue will be lower than in 2010. The effects of the take-or-pay clause on the 2011 accounts and eventually on the Company’s net financial position will be recognized at the end of the contractual year of collection (the thermal year ending September 30 or the calendar year as the case may be). Looking forward, management believes that based on its current assessment of the gas scenario the Company will fail to fulfill its minimum off-take obligations for the next two to three years, albeit at a lower pace in comparison with the peak-values registered in 2010.

Eni Interim Consolidated Report / Financial review and other information

The Company’s long-term ability to recover those pre-paid volumes within contractual terms and fulfill minimum take obligations in future years will depend on a number of factors, including the possible evolution of the gas environment and the competitiveness of Eni’s cost position, while on a positive note ongoing Libyan tensions and the shut down of the GreenStream pipeline may possibly help Eni counteract those negative trends as the Company could be able to replace supplies from Libya with gas from its large portfolio of supplies. That latter trend will evolve depending on how long such tensions will last, which for the time being cannot be foreseen. Considering the Company’s expectations about future trends in the gas environment in Europe and internal sales plans and unit margin projections for the next four-year period and subsequent years, management believes that in the long-term the Company will recover volumes of gas which have been pre-paid in the years 2009 and 2010 due to the take-or-pay clause and also possible new volumes associated with the contractual clause due to the uncertainties and weak conditions in the gas market over the next few years. Even if financing associated with cash advances is factored in, the net present value associated with those long-term purchase contracts discounted at the weighted average cost of capital for the Gas & Power segment still remains a positive and consequently those contracts do not fall within the category of the onerous contract provided by IAS 37. The economical and financial projections related to the take-or-pay contracts incorporate the management’s assumption to renegotiate better economic terms within such contracts. Should the outcome of those renegotiations fall short of management’s expectations and absent a solid recovery in the fundamentals of the gas sector, management believes that future results of operations and cash flows of the Company’s gas business will be negatively affected. Risks associated with sector-specific regulations in Italy Material aspects regarding the Italian gas sector regulations are legal limits on the market share of each operator in Italy, regulated access to infrastructures (transport backbones, storage fields, distribution networks and LNG terminals), and the functional and decisional unbundling of undertakings owning and managing gas infrastructures within vertically-integrated group companies. Also the Italian Authority for Electricity and Gas is entrusted with certain powers in the matters of setting tariffs for transport, distribution, storage and re-gasification services, as well as in approving specific codes for each regulated activity, monitoring natural gas prices and setting pricing mechanisms for supplies to users which are entitled to be safeguarded in accordance with applicable regulations. In fact, those clients which mainly include households and residential customers have right to obtain gas from their suppliers at a regulated tariff set by the Authority. In 2011, new legislation went effective which implemented a mechanism of market shares as per Legislative Decree No. 130 of August 13, 2010, titled "New measures to improve competitiveness in the natural gas market and to ensure the transfer of economic benefits to final customers". This legislation replaced the previous system of antitrust threshold defined by Legislative Decree No. 164 of May 23, 2000. The new decree introduces a 40% ceiling to the wholesale market share of each Italian gas operator. This ceiling can be raised to 55.9% in case an operator commits itself to building new storage |  | capacity in Italy for a total of 4 bcm within five years from enactment of the decree. The new capacity is to be allocated to industrial and power generation customers. In case of violation of the mandatory thresholds, an operator is obliged to execute gas release measures at regulated prices. Eni plans to build new storage capacity and, in the meantime, intends to adopt measures and bear the associated expenses to make 50% of that planned capacity available to requesting customers. Eni believes that this new gas regulation will increase the competitiveness of the wholesale natural gas market in Italy. On June 1, 2011, the Italian Council of Ministers approved a Legislative Decree intended to enact European Directive 2009/72 EC, 2009/73/EC, and 2008/92/EC (Third Gas Directive) into Italian legislation. The Decree establishes the adoption of the functional unbundling, the so-called Independent Transmission Operator (ITO) model for the main Italian gas transport operator which is an Eni subsidiary (Snam Rete Gas). On the basis of the enacted legislative decree, Eni could retain control of Snam Rete Gas by ensuring the decisional and functional independence of its subsidiary. Eni already complies with the regime of functional unbundling for Snam Rete Gas as set by Decision No. 11/07 and updated by Resolution No. 253/07 of the Authority for Electricity and Gas. The adoption of ITO model into Italian legislation allows Eni to avoid the risk of proprietary separation of the 52.54%-owned subsidiary (as of December 31, 2010). In 2010, consolidated financial statements, Snam Rete Gas accounted for approximately 13% of the Group’s total assets, 2% of the Group’s total revenues and 12% of the Group’s operating profits. However, based on Law 290/2003, Italian vertically-integrated gas companies are still prohibited from retaining a shareholding in excess of 20% in undertakings which manage and own large pieces of the national transport network, including Snam Rete Gas. The deadline to comply with this provision, which the original law had fixed on December 31, 2008, is due 24 months after the promulgation of a specific Decree of the President of the Council of Ministers which is intended to set terms and conditions for the divestment. The decree has yet to be enacted. At the actual stage the Company is unable to forecast any possible evolution on the matter. Authority decision in the field of determination of the economic conditions of supply to residential customers could limit the capacity of the operators to transfer increases in the cost of the raw material to the final price. The Authority has established a mechanism for updating tariffs by indexing them to a preset basket of hydrocarbons. Also a floor has been established in the form of a fixed amount that applies only at certain low level of international prices of hydrocarbons. Clients who are eligible to the tariff mechanism set by the Authority are those residential clients who did not opt for choosing a supplier at the opening of the market (including those who consume less than 200,000 cm per year and residential buildings). The above-mentioned Legislative Decree No. 130/2010 enlarged this category by including all customers consuming less than 50,000 cm per year and certain public services (for example hospitals and other assistance facilities). In its latest intervention on this issue, the Authority for Electricity and Gas with Resolution ARG/gas 89/10 amended the current mechanism that is used to update tariffs in supplies to residential users. Following this Resolution, the Authority resolved to provide, for the thermal year October 1, 2010

Eni Interim Consolidated Report / Financial review and other information

-September 30, 2011, a fixed reduction of 7.5% of the raw material cost component in the final price of supplies to residential users. In addition with Resolution ARG/gas 77/11, the AEEG provided for the thermal year October 1, 2011-September 30, 2012 a reduction of 6.5% of the raw material cost component. (Eni is currently evaluating the possible impact of the latter resolution and the appeals against ARG/gas 89/10). These resolutions will negatively affect Eni’s results of operations and cash flows for the 2010-2012 thermal years, considering the negative impact on unit margins in sales to residential customers. Administrative appeals against the Authority’s resolution, which have been filed by many operators including Eni, might possibly impact that matter. Also certain provisions of law may limit the Company’s ability to set commercial margins. Specifically, Law Decree No. 112 of June 2008 forbids energy companies to pass to prices to final customers the higher income taxes incurred in connection with a supplemental tax rate of 6.5 percentage points introduced by the same decree on energy companies with a yearly turnover in excess of euro 25 million like Eni. The current regulation of access to the Italian gas transport network was set by Decision No. 137/2002 of the Authority for Electricity and Gas. This resolution establishes priority criteria for transport capacity entitlements at points where the Italian transport network connects with international import pipelines (the so-called entry points to the Italian transport system). Specifically, operators that are party to take-or-pay purchase contracts, as in the case of Eni, are entitled to a priority in allocating available transport capacity within the limit of average daily contractual volumes. Gas volumes exceeding average daily contractual volumes are not entitled to any priority and, in case of congestion at any entry points, they are entitled available capacity on a proportionate basis together with all pending requests for capacity entitlements. The ability of Eni to collect gas volumes exceeding average daily volumes as provided by its take-or-pay purchase contracts represents an important operational flexibility that the Company uses to satisfy demand peaks. In planning its commercial flows, the Company normally assumes to fully utilize its contractual flexibility and to obtain the necessary capacity entitlements at the entry points to the national transport network. Eni believes that Decision No. 137/2002 is in contrast with the rationale of the European regulatory framework on the gas market as provided in European Directive 2003/55/EC. Based on that belief, the Company has opened an administrative procedure to repeal Decision No. 137/2002 before an administrative court which has recently confirmed in part Eni’s position. An upper grade court also confirmed the Company’s position. Specifically, the Court stated that the purchase of contractual flexibility is an obligation on part of the importer, which responds to a collective interest. According to the Court, there is no reasonable motivation whereby volumes corresponding to such contractual flexibility should not be granted priority in the access to the network, also in case congestion occurs. At the moment, however, no case of congestion occurred at entry points to the Italian transport infrastructure so as to impair Eni’s marketing plans. As of recently, the Italian administrative authorities released a number of resolutions intended to increase competition in the natural gas market in Italy: - in 2010, a national trading platform was implemented where gas importers must trade volumes of gas corresponding to a legal obligation on part of Italian importers and producers. Under those provisions, importers from extra-EU Countries are |  | required to supply a set percentage of imported volumes in a given thermal year and to trade them at the national trading platform on a spot basis. Permission to import gas from extra-EU Countries is granted to gas operators upon fulfillment of that obligation. Also royalties in-kind owed to the Italian State on gas production are to be traded on that trading platform. The new trading platform is expected to develop a spot market for natural gas in Italy; - a number of administrative provisions relating the so-called gas release measures have been enacted in an effort by Italian administrative authorities to boost the level of competition and liquidity of the Italian gas market. Those measures have strongly affected Eni’s marketing activity in Italy. It is worth mentioning that the Legislative Decree No. 130/2010 intended to increase competitiveness in the gas market, provides a mechanism of gas release for a maximum of 4 bcm in the two subsequent thermal years in case of Eni failure to comply with the mandatory ceiling on the market share; - the Italian Authority for Electricity and Gas plans to commence a spot market to balance daily flows of supply and demand based on the relative competitiveness of individual bids. The start-up date will likely fall in December 2011. Gas operators will bear the pricing risk associated with such a market. Measures aimed at increasing competitiveness in the Italian gas market represent risk factors and uncertainties to Eni’s gas business. Management believes that any developments in that matter may negatively affect the Company’s expected results of operations and cash flow in its gas business. Specific risks associated with the exploration and production of oil and natural gas Exploration and production of oil and natural gas requires high levels of capital expenditure and entails particular economic risks. It is subject to natural hazards and other uncertainties including those relating to the physical characteristics of oil or natural gas fields. Exploratory activity involves numerous risks including the risk of dry holes or failure to find commercial quantities of hydrocarbons. Developing and marketing hydrocarbons reserves typically requires several years after a discovery is made. This is because a development project involves an array of complex and lengthy activities, including appraising a discovery in order to evaluate its commerciality, sanctioning a development project and building and commissioning relating facilities. As a consequence, rates of return of such long lead-time projects are exposed to the volatility of oil and gas prices and the risk of an increase in developing and lifting costs, resulting in lower rates of return. This set of circumstances is particularly important to those projects intended to develop reserves located in deep waters and harsh environments, where the majority of Eni’s planned and ongoing projects is located. As events occurred in 2010 in the Gulf of Mexico have shown, exploration and production carries certain inherent risks, especially deep water drilling. Accidents at a single well can lead to loss of life, environmental damage and consequently potential economic losses that could have a material and adverse effect on the business, results of operation and prospects of the Group.

Eni Interim Consolidated Report / Financial review and other information

Risks associated with the cyclicality of the oil and gas sector Eni’s results of operations and cash flow, specifically E&P Division, depend heavily on trends in oil and gas prices. Generally speaking, an increase in oil prices positively impact Eni’s consolidated operating result; vice-versa in case of a decline in oil prices. The same applies to gas prices. In the first half of 2011, oil prices averaged $111.16 a barrel, representing an increase of 44% from a year earlier driving up the operating result. That trend reflected the global economic recovery that boosted raw materials prices in addition to the impact of ongoing Libyan political instability and tensions. In the same period, upstream gas realizations increased by 7%. Volatile oil prices impact the performance of the Company’s business units in different ways. Also, trends in oil prices are a key variable in preparing the Company’s investment plans. The Company’s main capital projects to develop reserves normally require lengthy and complex activities for assessing all technical and commercial aspects and developing and marketing the reserves. As a consequence, return rates of such projects are exposed to the volatility of oil and gas prices which may be substantially lower with respect to prices assumed when the investment decision was made, resulting in lower rates of return. The Company, like other players in the industry, assesses its oil&gas projects based on long-term scenarios for oil prices, which reflect management’s best assumptions about the underlying fundamentals of global demand and supply. This support the expected project profitability in the downward phases of oil&gas cycle. Volatile oil prices represent an uncertainty factor in view of achieving the Company’s operating targets of production growth and reserve replacement due to the relevant amount of Production Sharing Agreements in Eni’s portfolio. Under such contracts, the Company is entitled to receive a portion of the production, the sale of which should cover expenditures incurred and earn the Company a share of profit. Accordingly, the higher the reference prices for crude oil used to determine production and reserves entitlements, the lower the number of barrels to cover the same dollar amounts hence the amounts of booked production and reserves; and vice-versa. For the current year, the Company estimates that production entitlements in its PSAs would decrease on average by approximately 1,000 bbl/d for a $1 increase in oil prices compared to Eni’s assumptions for oil prices at 70 $/bbl that have been used in the Company’s 2011-2014 four year plan. However, this sensitivity analysis only applies to small deviations from the 70 $/bbl scenario and the impact on Eni’s production may increase more than proportionally as the deviation increases. This sensitivity may change in the future. This sensitivity analysis relates to the existing Eni portfolio and might vary in the future. In the Gas & Power segment, rising oil prices represent a risk to the segment profitability as gas supplies are mainly indexed to the cost of oil and certain refined products, while selling prices particularly outside Italy are increasingly linked to certain market benchmarks quoted at continental hubs. In the current trading environment, spot prices at those hubs are particularly depressed due to oversupply conditions. In addition, the Italian Authority for Electricity and Gas may limit the ability of the Company to pass cost increases onto selling prices in supplies to residential customers and small businesses as the Authority regulates the indexation mechanism |  | of the raw material cost in selling formulae to those customers. (For further details see Gas & Power specific-sector risks discussed above). The Refining & Marketing and the Petrochemical Divisions are also exposed to movements in oil prices and the speed at which the prices of refined products and petrochemical products adjust to reflect changes in the cost of oil-based feedstock. Normally, a time lag occurs between movements in oil prices and those of refined and petrochemical products. As a consequence, in a period of rapidly escalating feedstock costs, margins on refined and petrochemical products are negatively affected in the short-term. In the first half of 2011, the Refining & Marketing segment recorded wider adjusted operating loss than a year ago due to unprofitable refining margins as high costs of oil-based feedstock were only partially transferred to product prices pressured by weak demand, high inventories and excess capacity. In addition, increased oil prices triggered higher costs of energy utilities which are typically indexed to it. The impact of those trends was partially mitigated by widening price differentials between sweet vs. sour crudes and improving spreads of valuable distillates compared to heating oil which helped improve margins on complex throughputs. In addition, to cope with volatile, unprofitable refining margins, management implemented initiatives to boost efficiency and capture margin improvements by optimizing refinery cycles. Looking forward, management expects that the refining scenario will remain weak as underlying fundamentals are unlikely to change in the short-term due to weak industry-specific fundamentals. In the first quarter of 2011, rapidly escalating supply costs have also affected marketing margins in the Company’s retail business in Italy as prices at the pump adjusted to rising crude costs with time lags. However, effective marketing initiatives helped the Company’s margins in the second quarter and looking forward management expects sales volumes to receive a boost from the driving season. In addition to volatile oil-based feedstock costs, Eni’s petrochemical operations are exposed to the cyclicality of demand due to the commoditized nature of Eni’s product portfolio and underlying weaknesses in the industry plagued by low-entry barriers, excess capacity and intense competitive pressures. However, the global economic recovery and a good performance of certain niche products, in particular elastomers, have been supporting an improved performance of Eni’s petrochemicals operations from 2010 with the first half results showing a 40% gain in reducing the adjusted loss from the year-earlier period. In the remainder of 2011 management expects that it is likely that higher costs of oil-based feedstock will squeeze product margins in spite of good signs of demand stability. The Engineering & Construction segment is exposed to the volatility of the oil cycle considering that oil companies tend to reduce capital expenditures and reschedule exploration and development projects during a downturn. This business unit has managed through the years to progressively reduce its exposure to the more volatile segments of the industry leveraging on higher portfolio diversification and a strong competitive position in the segment of projects in frontier areas that are traditionally less exposed to the cyclical nature of this market. The entry into operations of new distinctive assets in 2010 and 2011 coupled with the size and quality of the backlog and the strong operating performance in terms of project executions, underpin expectations for further significant strengthening of Saipem’s competitive position in the medium-term, ensuring a good level of result stability.

Eni Interim Consolidated Report / Financial review and other information

Outlook

Management expects that the global economic recovery will continue to progress at a modest pace during the year 2011. Nonetheless, the 2011 outlook is also characterized by a certain degree of uncertainty and volatility in light of ongoing macroeconomic and geopolitical developments, particularly the evolution of the Libyan crisis. Eni forecasts an upward trend for Brent crude oil prices also supported by healthier global oil demand. For its short-term economic and financial projections, Eni assumes an average Brent price of 115 $/bbl for the full year 2011. Management expects that the European gas market will remain weak as sluggish demand growth is insufficient to absorb current oversupplies and ongoing competitive pressures undermine gas operators’ profitability. Refining margins are expected to remain at unprofitable levels due to weak underlying fundamentals (sluggish demand and excess capacity) and high feedstock costs. Against this backdrop, management expectations about the main trends in the Company’s businesses for 2011 are disclosed below. - Production of liquids and natural gas: is forecast to decline from 2010 (1.815 million boe/d was the actual level in 2010 at 80 $/bbl) at the Company’s pricing scenario of 115 $/bbl for the full year. The decline is expected as a result of volume losses in Libya following the shutdown of almost all of the Company’s production facilities. Better production performance at the Company’s assets elsewhere in the world will help partly offset the impact associated with rising crude oil prices on PSAs entitlements. Assuming the actual production level at 50 kboe/d in Libya for the remainder of 2011, management forecasts a 10 percentage points reduction in the expected production plateau for the full year at a constant pricing scenario. Management has been implementing its plans to target production growth in the Company’s assets by ramping up fields that were started in 2010, starting up new fields in the USA, Australia, Egypt, Italy and Algeria, as well as executing production optimizations in particular in Nigeria, Norway, Egypt, Angola and the United Kingdom; - Worldwide gas sales: are expected to grow from 2010 (in 2010 actual sales amounted to 97.06 bcm), in spite of sales losses to certain Italian importers due to lower availability of gas from Libya. Management plans to drive volume growth in Italy, leveraging clients additions in the power generation, industrial and wholesale segments, as well as regaining significant market share, and capitalizing on organic growth in key |  | European markets. Considering mounting competitive pressure in the gas market, the achievement of the planned volume targets will be underpinned by strengthening the Company’s leadership on the European market; marketing actions intended to strengthen the customer base in the domestic market and renegotiating the Company’s long-term gas purchase contracts. The cash flow impact associated with lower sales to Italian shippers will be offset by expected lower cash outflows associated with the Company’s take-or-pay gas purchase contracts as the Company is planning to meet lower availability of Libyan gas with gas from other sources in its portfolio; - Regulated businesses in Italy: will benefit from the pre-set regulatory return on new capital expenditure and continuing efficiency actions; - Refining throughputs on Eni’s account: are expected to slightly decline compared to 2010 (actual throughputs in 2010 were 34.8 mmtonnes). The decline is mainly expected at the Venice refinery due to difficulties in supplying Libyan crude oil. Higher volumes are expected to be processed at the Sannazzaro and Taranto refineries and optimization of refinery cycles, as well as efficiency actions are expected to be implemented in response to a negative trading environment; - Retail sales of refined products in Italy and the rest of Europe: are expected to be slightly lower than in 2010 (11.73 mmtonnes in 2010) against the backdrop of weaker demand. Management plans to counteract that negative trend by leveraging selective pricing and marketing initiatives, developing the "non-oil" business and service upgrade; - The Engineering & Construction business: confirms solid results due to increasing turnover and a robust order backlog. In 2011, management plans to make capital expenditure broadly in line with 2010 (euro 13.87 billion was invested in 2010) mainly directed to developing giant fields and starting production at new important fields in the Exploration & Production Division, refinery upgrading related in particular to the realization of the EST project, completing the program of enhancing Saipem’s fleet of vessels and rigs, and upgrading the natural gas transport infrastructures. Assuming a Brent price of 115 $/barrel and the planned divestment of certain assets, management forecasts that the ratio of net borrowings to total equity (leverage) at year-end will be lower than in 2010.

The glossary of oil and gas terms is available on Eni’s web page at the address eni.com. Below is a selection of the most frequently used terms. Financial terms - Dividend Yield Measures the return on a share based on dividends for the year. Calculated as the ratio of dividends per share of the year and the average reference price of shares in the last month of the year. Generally, companies tend to keep a constant dividend yield, as shareholders compare this indicator with the yield of other shares or other financial instruments (e.g. bonds). - Leverage Is a measure of a company’s debt, calculated as the ratio between net financial debt and shareholders’ equity, including minority interests. - ROACE Return On Average Capital Employed Is the return on average capital invested, calculated as the ratio between net income before minority interests, plus net financial charges on net financial debt, less the related tax effect and net average capital employed. Oil and natural gas activities - Average reserve life index Ratio between the amount of reserves at the end of the year and total production for the year. - Barrel Volume unit corresponding to 159 liters. A barrel of oil corresponds to about 0.137 metric tons. - Boe (Barrel of Oil Equivalent) Is used as a standard unit measure for oil and natural gas. The latter is converted from 5,550 standard cubic feet of gas per barrel of oil equivalent. - Carbon Capture and Storage (CCS) Technique of CO2 capture and storage through an integrated process that involves: (i) capture of CO2 associated with large combustion plants, power generation plants, industrial point sources, as well as natural gas fields; (ii) transport to the storage sites, generally via pipeline; and (iii) sequestration in geological sites on land or under the sea floor. - Concession contracts Contracts currently applied mainly in Western Countries regulating relationships between States and oil companies with regards to hydrocarbon exploration and production. The company holding the mining concession has |  | an exclusive on mining activities and for this reason it acquires a right on hydrocarbons extracted, against the payment of royalties to the State on production and taxes on oil revenues. - Condensates These are light hydrocarbons produced along with gas, that condense to a liquid state at normal temperature and pressure for surface production facilities. - Contingent resources Amounts of oil and gas estimated at a given date that are potentially recoverable by means of development projects that are not considered commercially recoverable due to one or more contingency. - Conversion Refinery process allowing the transformation of heavy fractions into lighter fractions. Conversion processes are cracking, visbreaking, coking, the gasification of refinery residues, etc. The ration of overall treatment capacity of these plants and that of primary crude fractioning plants is the conversion rate of a refinery. Flexible refineries have higher rates and higher profitability. - Deep waters Waters deeper than 200 meters. - Development Drilling and other post-exploration activities aimed at the production of oil and gas. - Elastomers (or Rubber) Polymers, either natural or synthetic, which, unlike plastic, when stress is applied, return, to a certain degree, to their original shape, once the stress ceases to be applied. The main synthetic elastomers are polybutadiene (BR), styrene-butadiene rubber (SBR), ethylenepropylene rubber (EPR), thermoplastic rubber (TPR) and nitrylic rubber (NBR). - Enhanced recovery Techniques used to increase or stretch over time the production of wells. - EPC (Engineering, Procurement, Construction) A contract typical of onshore construction of large plants in which the contractor supplies engineering, procurement and construction of the plant. The contract is defined "turnkey" when the plant is supplied for start-up. - EPIC (Engineering, Procurement, Installation, Commissioning) A contract typical of offshore construction of complex projects (such as the installation of production platforms or FPSO systems) in which the global or main contractor, usually a company or a consortium of companies, supplies engineering, procurement, construction of plant and infrastructure, transport to the site and all preparatory activities for the start-up of plants.

- Exploration Oil and natural gas exploration that includes land surveys, geological and geophysical studies, seismic data gathering and analysis, and well drilling. - FPSO vessel Floating, Production, Storage and Offloading system made up of a large capacity oil tanker including a large hydrocarbon treatment plant. This system, moored at the bow in order to maintain a geostationary position, is in fact a temporary fixed platform linking the underwater wellheads to the treatment, storage and offloading systems onboard by means of risers from the seabed. - Green House Gases (GHG) Gases in the atmosphere, transparent to solar radiation, can consistently trap infrared radiation emitted by the earth’s surface, atmosphere and clouds. The six relevant greenhouse gases covered by the Kyoto Protocol are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6). GHGs absorb and emit radiation at specific wavelengths within the range of infrared radiation determining the so called greenhouse phenomenon and the related increase of earth’s average temperature. - Infilling wells Infilling wells are wells drilled in a producing area in order to improve the recovery of hydrocarbons from the field and to maintain and/or increase production levels. - LNG Liquefied Natural Gas obtained through the cooling of natural gas to minus 160 °C at normal pressure. The gas is liquefied to allow transportation from the place of extraction to the sites at which it is transformed and consumed. One ton of LNG corresponds to 1,400 cubic meters of gas. - LPG Liquefied Petroleum Gas, a mix of light petroleum fractions, gaseous at normal pressure and easily liquefied at room temperature through limited compression. - Mineral Potential (Potentially recoverable hydrocarbon volumes) Estimated recoverable volumes which cannot be defined as reserves due to a number of reasons, such as the temporary lack of viable markets, a possible commercial recovery dependent on the development of new technologies, or for their location in accumulations yet to be developed or where evaluation of known accumulations is still at an early stage. - Mineral Storage Volumes of natural gas required for allowing optimal operation of natural gas fields in Italy for technical and economic reasons. - Modulation Storage Volumes of natural gas required for meeting hourly, daily and seasonal swings of demand. - Natural gas liquids Liquid or liquefied hydrocarbons recovered from natural gas through separation equipment or natural gas treatment plants. Propane, normal-butane and isobutane, isopentane and pentane plus, that used to be defined natural gasoline, are natural gas liquids. |  | - Network Code A code containing norms and regulations for access to, management and operation of natural gas pipelines. - Offshore/Onshore The term offshore indicates a portion of open sea and, by induction, the activities carried out in such area, while onshore refers to land operations. - Olefins (or Alkenes) Hydrocarbons that are particularly active chemically, used for this reason as raw materials in the synthesis of intermediate products and of polymers. - Over/Underlifting Agreements stipulated between partners regulate the right of each to its share in the production of a set period of time. Amounts different from the agreed ones determine temporary over/underlifting situations. - Possible reserves Possible reserves are those additional reserves that are less certain to be recovered than probable reserves. - Probable reserves Probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered. - Production Sharing Agreement Contract in use in non OECD Countries, regulating relationships between States and oil companies with regard to the exploration and production of hydrocarbons. The mining concession is assigned to the national oil company jointly with the foreign oil company who has exclusive right to perform exploration, development and production activities and can enter agreements with other local or international entities. In this type of contract the national oil company assigns to the international contractor the task of performing exploration and production with the contractor’s equipment and financial resources. Exploration risks are borne by the contractor and production is divided into two portions: "Cost Oil" is used to recover costs borne by the contractor, "Profit Oil" is divided between contractor and national company according to variable schemes and represents the profit deriving from exploration and production. Further terms and conditions may vary from one Country to the other. - Proved reserves Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from know reservoirs, and under existing economic conditions. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. - Reserves Quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that will exist, the legal right to produce or a revenue interest in the production, installed means of delivering

oil and gas or related substances to market, and all permits and financing required to implement the project. Reserves can be: (i) developed reserves quantities of oil and gas anticipated to be through installed extraction equipment and infrastructure operational at the time of the reserves estimate; (ii) undeveloped reserves: oil and gas expected to be recovered from new wells, facilities and operating methods. - Reserve replacement ratio Measure of the reserves produced replaced by proved reserves. Indicates the company’s ability to add new reserves through exploration and purchase of property. A rate higher than 100% indicates that more reserves were added than produced in the period. The ratio should be averaged on a three-year period in order to reduce the distortion deriving from the purchase of proved property, the revision of previous estimates, enhanced recovery, improvement in recovery rates and changes in the value of reserves – in PSAs – due to changes in international oil prices. Management also calculates this ratio by excluding the effect of the purchase of proved property in order to better assess the underlying performance of the Company’s operations. - Ship or pay Clause included in natural gas transportation contracts according to which the customer for which the transportation is carried out is bound to pay for the transportation of the gas also in case the gas is not transported. - Strategic Storage Volumes of natural gas required for covering lack or reduction of supplies from extra-European sources or crises in the natural gas system. - Swap In the gas sector, the term is referred to a buy/sell contract between some counterparties and is generally aimed to the optimization of transport costs and respective commitments in purchasing and supplying. |  | - Take-or-pay Clause included in natural gas purchase contracts according to which the purchaser is bound to pay the contractual price or a fraction of such price for a minimum quantity of the gas set in the contract also in case it is not collected by the customer. The customer has the option of collecting the gas paid and not delivered at a price equal to the residual fraction of the price set in the contract in subsequent contract years. - Upstream/Downstream The term upstream refers to all hydrocarbon exploration and production activities. The term downstream includes all activities inherent to the oil sector that are downstream of exploration and production activities. - Volatile organic compound (VOC) Fluid or vapor chemical compounds capable to evaporating easily at room temperature. Over 300 compounds fall in this category. Of these, most relevant are: aliphatic hydrocarbons, terpenes, aromatic hydrocarbons, halogenated hydrocarbons, alcohols, esters, ketones and aldehydes. - Wholesale sales Domestic sales of refined products to wholesalers/distributors (mainly gasoil), public administrations and end consumers, such as industrial plants, power stations (fuel oil), airlines (jet fuel), transport companies, big buildings and households. They do not include distribution through the service station network, marine bunkering, sales to oil and petrochemical companies, importers and international organizations. - Workover Intervention on a well for performing significant maintenance and substitution of basic equipment for the collection and transport to the surface of liquids contained in a field.

Eni Condensed consolidated interim financial statements / Notes to financial statements

Notes to the condensed consolidated interim financial statements 1 Basis of presentation The Condensed Consolidated Interim Financial Statements of Eni Group have been prepared in accordance with IAS 34 "Interim Financial Reporting". The statements are the same adopted in the Annual Report 2010. The Condensed Consolidated Interim Financial Statements have been prepared in accordance with the same principles of consolidation and measurement criteria described in the Annual Report 2010. The report includes selected explanatory notes. Related party disclosures have been prepared according to the provisions of IAS 24 "Related Party Disclosures", effective starting from 2011, that enhance the definition of related party and the disclosure to be reported. Income taxes have been calculated based on the estimated taxable profit. Tax payables and receivables have been measured at the amount expected to be paid to/recovered from tax authorities, applying tax laws that have been enacted or substantively enacted at the end of the period and using tax rates estimated on an annual basis. The Condensed Consolidated Interim Financial Statements at June 30, 2011, were approved by Eni’s Board of Directors on July 28, 2011. A limited review has been carried out by the independent auditor Reconta Ernst & Young SpA; a limited review is substantially less in scope than an audit performed in accordance with generally accepted auditing standards. Amounts in the financial statements and in the notes are expressed in millions of euros (euro million). 2 Use of accounting estimates For a description of the accounting estimates used see the Annual Report 2010. 3 Recent accounting principles As regards the recent accounting principles, in addition to those indicated in the Annual Report 2010, the main pronouncements issued by IASB and not yet been endorsed by European Union are indicated hereinafter. On May 12, 2011, IASB issued IFRS 10 "Consolidated Financial Statements" and the revised IAS 27 "Separate Financial Statements" which respectively state principles for presentation and preparation of consolidated and separate financial statements. IFRS 10 provisions provide, interalia, a new definition of control to be consistently applied to all entities (included vehicles). According to this definition, an entity controls an investee when it is exposed, or has rights, to its |  | (positive and negative) returns and has the ability to affect those returns through its power over the investee. The standard provides some indicators to be considered assessing control which include, interalia, potential voting rights, protective rights, the presence of agency relationships and franchise agreements. Furthermore, the new provisions acknowledge the existence of control even if the investor holds less than majority of voting rights due to shareholding dispersion or passive attitude of other shareholders. IFRS 10 and revised IAS 27 shall be applied for annual periods beginning on or after January 1, 2013. On May 12, 2011, IASB issued IFRS 11 "Joint Arrangements" and the revised IAS 28 "Investments in Associates and Joint Ventures". Depending on the rights and obligations of the parties arising from the arrangement, IFRS 11 classifies joint arrangements into two types – joint operations and joint ventures – and states the required accounting treatment. With reference to joint ventures, the new provisions require to account for them using the equity method, eliminating proportionate consolidation. The revised IAS 28 defines, interalia, the accounting treatment to adopt in case of the disposal of an interest, or a portion of an interest, in a joint venture or an associate. IFRS 11 and revised IAS 28 shall be applied for annual periods beginning on or after January 1, 2013. On May 12, 2011, IASB issued IFRS 12 "Disclosure of Interests in Other Entities" that indicate the disclosure to provide in consolidated financial statements regarding subsidiaries, joint arrangements, associates and unconsolidated structured entities. IFRS 12 shall be applied for annual periods beginning on or after January 1, 2013. On May 12, 2011, IASB issued IFRS 13 "Fair Value Measurement" in order to define a framework for fair value measurements and disclosures. Fair value is defined as the price that would be received to sell an asset (or paid to transfer a liability) in an orderly transaction between market participants. IFRS 13 shall be applied for annual periods beginning on or after January 1, 2013. On June 16, 2011 IASB issued Amendments to IAS 1 "Presentation of Items of Other Comprehensive Income" which require, interalia, entities to group together, within other comprehensive income, items which may be reclassified to profit and loss account on the basis of provisions of applicable IFRSs (reclassification adjustments). The amendments shall be applied for annual periods beginning on or after July 1, 2012 (for Eni: 2013 financial statements). On June 16, 2011, IASB issued the revised IAS 19 "Employee Benefits" that requires, interalia, to recognize actuarial gains and losses in other comprehensive income, eliminating the possibility to adopt the corridor method. Actuarial gains and losses recognized in other comprehensive income will not be recycled through profit or loss account in subsequent periods. The new provisions require, interalia, additional disclosures with reference to defined benefit plans. The revised IAS 19 shall be applied for annual periods beginning on or after January 1, 2013. Eni is currently reviewing these principles to determine the likely impact on the Group’s results.

7 Other current assets

Other current assets were as follows:

(euro million) |  | Dec. 31, 2010 |  | June 30, 2011

Fair value of non-hedging derivatives |  | 596 |  | 764
Fair value of trading derivatives |  | 30 |  | 104
Fair value of cash flow hedge derivatives |  | 210 |  | 21
Other current assets |  | 514 |  | 469
|  | 1,350 |  | 1,358

Fair value of derivatives is determined using market quotations provided by primary info-provider, or in the absence of market information, appropriate valuation methods used on the marketplace.
Fair values of non-hedging derivatives of euro 764 million (euro 596 million at December 31, 2010) consisted of derivatives that do not meet the formal criteria to be designated as hedges under IFRS because they were entered into in order to manage the net business exposures in foreign currency exchange rates, interest rates or commodity prices. Therefore, such derivatives were not related to specific trade or financing transactions.
Fair value of trading derivatives of euro 104 million (euro 30 million at December 31, 2010) related to derivatives entered by the Gas & Power segment consistently with the new risk management model for an active managing of margins.
Fair value of cash flow hedge derivatives of euro 21 million (euro 210 million at December 31, 2010) pertained for euro 20 million (euro 210 million at December 31, 2010) to the Gas & Power segment. These derivatives were entered into to hedge the commodity risk in order to minimize the variability in future cash flows on highly probable future sale transactions or on already contracted sales due to different movements in commodity prices as sales prices can be influenced by spot prices quoted on continental hubs, whereas purchase costs are indexed to the price of oil and products. A similar scheme applies to exchange rate hedging derivatives. The effects of the evaluation at fair value of cash flow hedge derivatives are given in Note 23 – Shareholders’ equity and Note 27 – Operating expenses.

Property, plant and equipment |  | 139,612 |  | 72,208 |  | 67,404 |  | 5,871 |  | (3,160 | ) |  | (264 | ) |  | (100 | ) |  | (2,684 | ) |  | 95 |  | 67,162 |  | 140,073 |  | 72,911

Capital expenditures of euro 5,871 million (euro 6,415 million in the first half of 2010) essentially related to the Exploration & Production segment for euro 4,195 million (euro 4,629 million in the first half of 2010), the Engineering & Construction segment for euro 549 million (euro 789 million in the first half of 2010), the Gas & Power segment for euro 536 million (euro 524 million in the first half of 2010) and the Refining & Marketing segment for euro 314 million (euro 265 million in the first half of 2010).
The break-down by segment of impairments amounting to euro 264 million (euro 79 million in the first half of 2010) and the associated tax effect is provided below:

(euro million) | First half 2010 |  | First half 2011

Impairment |  |  |  |
- Exploration & Production |  | 29 |  | 141
- Refining & Marketing |  | 33 |  | 37
- Petrochemicals |  | 9 |  | 70
- Other segments |  | 8 |  | 16
|  | 79 |  | 264

- Other segments |  | 6 |  | 15
|  | 51 |  | 177

In assessing whether impairment is required, the carrying value of an asset, item of property, plant and equipment, is compared with its recoverable amount. The recoverable amount is the higher of the asset’s fair value less costs to sell and value in use. Given the nature of Eni’s activities, information on fair value of an asset is usually difficult to obtain unless negotiations with potential purchasers are in place. Therefore, the recoverability is checked by using the value in use which is calculated by discounting estimated cash flows arising from the use of the asset. The valuation is carried out for individual asset or for the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets (cash generating unit). During the first half of 2011, the composition of Group’s cash generating units has remained unchanged from the Annual Report 2010 (see the Annual Report 2010, Note 14). The recoverable amount is calculated by discounting the estimated cash flows deriving from the use of the CGU and, if significant and reasonably determinable, the cash flows deriving from its disposal at the end of its useful life. Recoverable amounts of the CGUs in the regulated businesses of gas transportation, distribution, storage and re-gasification equal their respective net borrowings recognized by Regulatory Authority, considering that the operating cost structure borne is recognized in the tariff regime set by Regulatory Authority (Regulatory Asset Base - RAB).
Cash flows are determined on the basis of the best information available at the moment of the assessment deriving:

(i) |  | for the first four years of the projection, from the Company’s four-year plan adopted by the top management for the valuation of assets’ value in use in the preparation of Annual Report 2010 and subsequent available reviews for the preparation of this interim report which provides information on expected oil and gas production volumes, sales volumes, capital expenditures, operating costs and margins and industrial and marketing set-up, as well as trends on the main macroeconomic variables, including inflation, nominal interest rates and exchange rates;
(ii) |  | beyond the four-year plan horizon, from the management’s assumptions for long-term trends in the main macroeconomic variables (inflation rates, oil

|  | prices, etc.) and from the cash flow projections based on the following factors: (a) for the oil&gas CGUs the residual life of the reserves and associated projections of operating costs and development expenditures; (b) for the CGUs of the Refining & Marketing segment, the economical and technical life of the plants and associated projections of operating costs, expenditures to support plant efficiency and refining and marketing margins; (c) for the CGUs of the Petrochemical segment, the economical and technical life of the plants and associated projections of expenditures to support plant efficiency, and normalized operating results plus depreciation; (d) for the CGUs of the gas market and the Engineering & Construction segment, the perpetuity method of the last-year-plan by using a nominal growth rate ranging from 0% to 2%; and (e) for the regulated businesses of gas transportation, distribution, storage and regasification, a terminal value equal to the regulatory asset base of the last-year-plan; and
(iii) |  | for the commodity prices, from the forward prices prevailing in the marketplace as of the balance sheet date for the first four years of the cash flow projections and the long-term price assumptions adopted by the Company’s management for strategic planning purposes for the following years.

Value-in-use is determined by discounting post-tax cash flows at the rate which corresponds for the Exploration & Production, Refining & Marketing and Petrochemical segments to the Company’s weighted average cost of capital net of the risk factor attributable to Saipem and to the G&P segment on an exclusive basis, which is subjected to autonomous assessment, and adjusted to consider risks specific to each Country of activity (adjusted post-tax WACC). Adjusted WACC used for impairment purposes in the 2011 Interim Consolidated Financial Report have ranged from 8% to 13% and have been consistent with those used for the impairment test of the Annual Report 2010. Post-tax cash flows and discount rates were adopted as they resulted in an assessment that substantially equal to a pre-tax assessment.
In the Exploration & Production segment asset impairments charges amounted to euro 141 million which primarily related to gas properties located in USA as a result of a changed price environment for commodities and downward reserve revisions. In the case of a single property impaired by a significant amount, the post-tax discount rate was 8% that equaled a pre-tax rate of 11.5%. In the Refining & Marketing and the Petrochemicals segment, the Company recorded small impairment charges of certain health, safety and environment projects that were written-off because they related to assets completely impaired in the previous reporting periods and for which is confirmed the lack of earning prospects.
In relation to assets held in Libya, all of Eni’s producing facilities came to halt including export through the GreenStream gas pipeline, with the sole exception of the Wafa field where it is supporting local production of electricity. Plants and pipelines were put into safety status and no damage has been reported. Eni is technically able to resume the gas output at a level similar to the pre-crisis flows in 2010 once the situation has returned to normal. Since March 2011 Eni has evacuated all its personnel and suspended ongoing exploration and development activities. Eni’s production in Libya is currently flowing at a rate of approximately 50 kboe/d down from the expected level of 280 kboe/d for the year. The result of the impairment test on Libyan assets confirmed the recoverability of the carrying amount even when considering a period of activity suspension much longer than current management’s expectations.
Due to the ongoing conflict and the limitations deriving from the requirement for Eni to comply with international sanctions against Libya, Eni formally notified the Libyan counterparty the occurrence of force majeure events in April 2011. Under such circumstances, the parties are discussing the necessary actions to mitigate the consequences of force majeure as required by contractual arrangements currently in force between Eni and its Libyan counterparty. Should the parties fail to agree upon mitigation actions and should force majeure last more than 2 years from notification, the petroleum contracts between Eni and its Libyan partner will terminate unless otherwise agreed. Eni has been pursuing and will continue to pursue all the necessary and possible actions to safeguard its investments in Libya.
Foreign currency translation differences of euro 2,684 million were primarily related to translation of entities accounts denominated in US dollar (euro 2,621 million).
Change in the scope of consolidation amounting to euro 100 million related to the loss of control of Petromar Lda.
Other changes of euro 95 million comprised the initial recognition and change in the estimated amount of the costs for dismantling and restoring sites for euro 73 million, which included an increase of euro 224 million referring to the Exploration & Production segment, partially offset by a decrease of euro 151 million referring to Stoccaggi Gas Italia SpA following a timing revision, prospectively starting from January 1, 2010, of the future expenditures for dismantling and restoring of gas storage sites that increased the settlement of such obligation by 20 years (corresponding to the length of possible extensions).
Such calculation method is in accordance with the cost-covering remuneration in the tariff regime set by the Authority for Electricity and Gas.
The following is a description of unproved mineral interests, included in tangible assets in progress and advances:

9 Intangible assets

Intangible assets were as follows:

(euro million) |  | Gross value at Dec. 31, 2010 |  | Provisions for amortization and impairments at Dec. 31, 2010 |  | Net value at Dec. 31, 2010 |  | Investments |  | Amortization |  | Impairments |  | Currency translation differences |  | Other changes |  | Net value at June 30, 2011 |  | Gross value at June 30, 2011 |  | Provisions for amortization and impairments at June 30, 2011

Intangible assets with finite useful lives |  | 15,024 |  | 8,027 |  | 6,997 |  | 744 |  | (864 | ) |  | (1 | ) |  | (53 | ) |  | (89 | ) |  | 6,734 |  | 15,391 |  | 8,657
Intangible assets with indefinite useful lives |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Goodwill |  |  |  |  |  | 4,175 |  |  |  |  |  |  |  |  |  | (18 | ) |  |  |  |  | 4,157 |  |  |  |
|  |  |  |  |  | 11,172 |  | 744 |  | (864 | ) |  | (1 | ) |  | (71 | ) |  | (89 | ) |  | 10,891 |  |  |  |

Capital expenditures of euro 744 million (euro 692 million in the first half of 2010) included exploration drilling expenditures of the Exploration & Production segment which were fully amortized as incurred for euro 469 million (euro 513 million in the first half of 2010). Amortization of euro 864 million (euro 898 million in the first half of 2010) included the amortization of license acquisition costs for euro 107 million (euro 117 million in the first half of 2010).
The carrying amount of goodwill at the end of the period was euro 4,157 million (euro 4,175 million at December 31, 2010). The break-down by operating segment is as follows:

(euro million) |  | Dec. 31, 2010 |  | June 30, 2011

Exploration & Production |  | 262 |  | 243
Gas & Power |  | 3,000 |  | 2,999
Refining & Marketing |  | 164 |  | 166
Engineering & Construction |  | 749 |  | 749
|  | 4,175 |  | 4,157

Goodwill acquired through business combinations has been allocated to the cash generating units ("CGUs") that are expected to benefit from the synergies of the acquisition. The CGUs of the Gas & Power segment are represented by such commercial business units whose cash flows are interdependent and therefore benefit from acquisition synergies. The recoverable amounts of the CGUs are determined by discounting the future cash flows deriving from the continuing use of the CGUs and, if significant and reasonably determinable, the cash flows deriving from its disposal at the end of their useful lives. Recoverable amounts of the CGUs in the regulated businesses of gas transportation, distribution, storage and re-gasification equal their respective regulatory asset base, considering that the operating cost structure borne is recognized in the tariff regime set by Regulatory Authority (Regulatory Asset Base - RAB).
Cash flows are determined on the basis of the best information available at the moment of the assessment deriving:

(i) |  | for the first four years of the projection, from the Company’s four-year plan adopted by the top management for the valuation of assets’ value in use in the preparation of Annual Report 2010 and subsequent available reviews for the preparation of this interim report which provides information on expected oil and gas production volumes, sales volumes, capital expenditures, operating costs and margins and industrial and marketing set-up, as well as trends on the main macroeconomic variables, including inflation, nominal interest rates and exchange rates;
(ii) |  | beyond the four-year plan horizon, from the management’s assumptions for long-term trends in the main macroeconomic variables (inflation rates, oil prices, etc.) and from the cash flow projections based on the following factors: (a) for the oil&gas CGUs the residual life of the reserves and associated projections of operating costs and development expenditures; (b) for the CGUs of the Refining & Marketing segment, the economical and technical life of the plants and associated projections of operating costs, expenditures to support plant efficiency and refining and marketing margins; (c) for the CGUs of the gas market and the Engineering & Construction segment, the perpetuity method of the last-year-plan by using a nominal growth rate ranging from 0% to 2%; and (d) for the regulated businesses of gas transportation, distribution, storage and regasification, a terminal value equal to the regulatory asset base of the last-year-plan; and
(iii) |  | for the commodity prices, from the forward prices prevailing in the marketplace as of the balance sheet date for the first four years of the cash flow projections and the long-term price assumptions adopted by the Company’s management for strategic planning purposes for the following years.

Value-in-use is determined by discounting post-tax cash flows at the rate which corresponds: (i) for the Exploration & Production, Refining & Marketing and Petrochemical segments to the Company’s weighted average cost of capital net of the risk factor attributable to Saipem and to the G&P segment on an exclusive basis, which is subjected to autonomous assessment, and adjusted to consider risks specific to each Country of activity (adjusted post-tax WACC). Adjusted WACC used for impairment purposes in the 2011 Interim Consolidated Financial Report have ranged from 8% to 13% and have been consistent with those used for the impairment test of the Annual Report 2010; (ii) the impairment test rate for the Gas & Power segment was estimated on the basis of a sample of comparable companies in the utility industry. The impairment test rate for the Engineering & Construction segment was derived from market data. Rates used in the Gas & Power segment were adjusted to take into consideration risks specific to each Country of activity, while rates used in the Engineering & Construction segment did not reflect any Country risks as most of the company assets are not permanently located in a specific Country. Adjusted WACC used for impairment purposes in the 2011 Interim Consolidated Financial Report have ranged

from 7% to 8% for the Gas & Power segment and amounted to 9% for the Engineering & Construction segment and have been consistent with those used for the impairment test of the Annual Report 2010; (iii) for the regulated activities in the Italian natural gas sector, the discount rates were assumed to be equal to the rates of return defined by the Italian Authority for Electricity and Gas. Post-tax cash flows and discount rates were adopted as they resulted in an assessment that substantially approximated a pre-tax assessment.
Goodwill has been allocated to the following CGUs:

Gas & Power segment

(euro million) |  | Dec. 31, 2010 |  | June 30, 2011

Domestic gas market |  | 767 |  | 767
Foreign gas market |  | 1,918 |  | 1,917
- of which European market |  | 1,722 |  | 1,722
Domestic natural gas transportation network |  | 305 |  | 305
Other |  | 10 |  | 10
|  | 3,000 |  | 2,999

Goodwill allocated to the CGU domestic market primarily pertained to goodwill recognized upon the buy-out of Italgas SpA minorities in 2003 through a public offering (euro 706 million). The relevant CGU is engaged in supplying gas to residential customers and small businesses.
Goodwill allocated to the CGU European market pertained to goodwill recognized upon allocating the purchase price of the Distrigas business combination in 2009. The CGU comprises Distrigas marketing activities and those activities managed directly or indirectly by the Gas & Power Division of the parent company Eni SpA, which includes marketing activities in North-West Europe including France, Germany, Benelux, the UK, Switzerland and Austria. Those business units jointly benefited from the business combination synergies.
The impairment review confirmed the recoverability of the carrying amount of both CGUs, domestic market and the European market. The key assumptions adopted for assessing the value-in-use of both the CGUs Italian market and European market included marketing margins, forecast sales volumes, the discount rate and the growth rates adopted to determine the terminal value. The determination of the value-in-use is based on the economic and financial projections of the four year plan used in the assessments made on the occasion of the 2010 financial statements which have been updated in view of the impairment review of the interim report as of June 30, 2011, to take into account continuing weak market conditions caused by oversupply, sluggish demand and rising competitive pressures. These trends will negatively affect future results of operations and cash flows of Eni’s gas business in the second half of 2011 and in 2012. In particular, the CGU European market will be negatively affected by the reduction in unit margins as a result of unprofitable differentials between oil-linked gas purchase costs provided in Eni’s long-term gas supply contracts and spot prices recorded at European hubs, which have become a prevailing reference benchmark for selling prices, and by reduced sales opportunity. Starting from 2013, management forecasts a recovery in the gas market as it projects increased unit margins and a robust growth in gas sales. In respect of the four-year plan adopted in the preparation of the Annual Report 2010, management updated the economic and financial projections for this interim report as follows: (i) volumes reduction by 1% on average in the 2011-2014 four year period; (ii) improved commercial unit margins from 2013; (iii) zero setting of the perpetuity growth rate (previously 1.6%); (iv) discount rate unchanged. These assumptions lead to a value-in-use of the European market CGU which substantially equals its carrying amount, including the allocated goodwill. Therefore, any downward revision of each of those parameters would trigger an impairment risk. Future cash flows of the CGU European market are estimated based on the economical and financial effects of the renegotiations of the Eni’s main gas supply contracts. Should the outcome of those renegotiations fall short of management’s expectations and absent a solid recovery in fundamentals of the gas sector, future results of operations and cash flows of the Company’s gas business could be negatively affected, with further consequences in terms of recoverability of the carrying amounts of the CGU European market. The terminal value of the CGUs European market and domestic market was estimated based on the perpetuity method of the last year of the plan assuming a long-term nominal growth rate equal to zero. Value in use of the CGU European market was assessed by discounting the associated post-tax cash flows at a post-tax rate of 7.5% that corresponds to the pre-tax rate of 10.3% (7.5% and 9.3%, respectively in the Annual Report 2010). Value in use of the CGU Italian market was assessed by discounting the associated post-tax cash flows at a post-tax rate of 7% that corresponds to the pre-tax rate of 11.7% (the same rates used in the Annual Report 2010).
The excess of the recoverable amount of the CGU domestic gas market over its carrying amount including the allocated portion of goodwill (headroom) amounting to euro 485 million would be reduced to zero under each of the following alternative hypothesis: (i) a decrease of 38% on average in the projected commercial margins; (ii) a decrease of 38% on average in the projected sales volumes; (iii) an increase of 4.7 percentage points in the discount rate; and (iv) a negative nominal growth rate of 6.4%. The recoverable amount of the CGU domestic gas market and the relevant sensitivity analysis were calculated solely on the basis of retail margins, thus excluding wholesale and business client margins (industrial, thermoelectric and others).
Goodwill allocated to the domestic natural gas transportation network CGU was recognized alongside the repurchase of own shares by Snam Rete Gas SpA and equals the difference between the purchase cost over the carrying amount of the corresponding share of net equity. The recoverable amount of the CGU is assessed based on its Regulatory Asset Base (RAB) as recognized by the Italian Authority for Electricity and Gas and is higher than its carrying amount, including the allocated goodwill. Management believes that no reasonably possible change in the assumptions adopted would cause the headroom of the CGU to be reduced to zero.

Engineering & Construction segment

(euro million) |  | Dec. 31, 2010 |  | June 30, 2011

Offshore constructions |  | 415 |  | 415
Onshore constructions |  | 318 |  | 318
Other |  | 16 |  | 16
|  | 749 |  | 749

The segment goodwill of euro 749 million was mainly recognized following the acquisition of Bouygues Offshore SA, now Saipem SA (euro 710 million) and allocated to the CGUs offshore and onshore.
The key assumptions adopted for assessing the recoverable amounts of the CGUs which related to operating results, the discount rate and the growth rates adopted to determine the terminal value. These assumptions, based on the four-year-plan approved by the Company’s top management and other indicators were unchanged as of the preparation of this interim report in respect of those used for the test in 2010. Therefore, the estimation of the recoverable amounts of the Offshore and Onshore construction CGUs, that exceed their carrying amounts including the relevant goodwill, and the zero setting hypothesis confirm those used in the Annual Report 2010.
The Exploration & Production and the Refining & Marketing segments tested their goodwill, yielding the following results: (i) in the Exploration & Production segment with goodwill amounting to euro 243 million, management believes that there are no reasonably possible changes in the pricing environment and production/cost profiles that would cause the headroom of the relevant CGUs to be reduced to zero. Goodwill mainly refers to the portion of the purchase price that was not allocated to proved or unproved mineral interests of the business combinations Lasmo, Burren Energy (Congo) and First Calgary (Algeria); and (ii) in the Refining & Marketing segment goodwill amounted to euro 166 million and referred to retail networks acquired in Czech Republic, Hungary and Slovakia in the 2008 for euro 68 million and in Austria in the 2010 for euro 76 million. The assumptions adopted for assessing the recoverable amounts of these CGUs are substantially aligned to those determined in the Annual Report 2010.

The reimbursement of the receivable is provided for in three annual installments starting from the date of the production beginning.
Fair value of derivatives is determined using market quotations provided by primary info-provider, or in the absence of market information, appropriate valuation methods generally accepted in the marketplace.
Fair values of non-hedging derivatives of euro 505 million (euro 392 million at December 31, 2010) consisted of derivatives that do not meet the formal criteria to be designated as hedges under IFRS because they were entered into in order to manage the net business exposures in foreign currency exchange rates, interest rates and commodity prices. Therefore, such derivatives were not related to specific trade or financing transactions.
Fair value of trading derivatives of euro 103 million (euro 28 million at December 31, 2010) related to derivatives entered by the Gas & Power segment consistently with the new risk management model for an active managing of margins.
Fair value of the cash flow hedge derivatives of euro 2 million (euro 102 million at December 31, 2010) referred to the Gas & Power segment. The effects of the evaluation at fair value of cash flow hedge derivatives are given in Note 23 – Shareholders’ equity and Note 27 – Operating expenses.
Other asset of euro 1,887 million (euro 1,624 million at December 31, 2010) comprised prepayments amounting to euro 1,711 million (euro 1,436 million at December 31, 2010) that were made to gas suppliers upon triggering the take-or-pay clause provided by the relevant long-term arrangement. The increase of euro 275 million related to the balance finally accounted only during the 2011 of the take-or-pay volumes for the 2010. In accordance to those arrangements, the Company is contractually required to off-take minimum annual quantities of gas, or in case of failure is held to pay the whole price or a fraction for the uncollected volumes up to the minimum annual quantity. The Company is entitled to collect the pre-paid volumes in future years alongside the contract execution and for its entire duration or a shorter term as the case may be. The carrying amounts of those deferred costs, which are substantially equivalent to a receivable in-kind, are stated at the purchase cost or the net realizable value, whichever is lower. Prior-years impairment losses are reversed up to the purchase cost, whenever market conditions indicate that impairment no longer exits or may have decreased. In future years, management plans to recover the prepaid volumes by regaining market share and expanding its sales volumes in the European gas market leveraging on strengthening the Company’s market leadership and consolidating its customer base in the Italian market through effective marketing actions in both the retail market and the industrial and thermoelectric sector. Those action plans coupled with perspectives of steady long-term demand growth until 2020 will enable the Company to absorb volumes pre-paid during the market downturn. The industrial and financial forecasts for the next four-year plan of the gas business and beyond took into consideration management’s assumptions to renegotiate better economic terms within the Company’s long-term gas purchase contracts, so as to restore the competitiveness of the Company’s cost position in the current depressed scenario for the gas sector. The renegotiation of revised contractual terms, including any price revisions and contractual flexibility, is established by such contractual clauses whereby parties are held to bring the contract back to the economic equilibrium in case of significant changes in the market environment, like the ones that have occurred since the second half 2008. Renegotiations involving all the Company’s main suppliers of gas are progressing. Should the outcome of those renegotiations fall short of management’s expectations and absent a solid recovery in fundamentals of the gas sector, management believes that future results of operations and cash flows of the Company’s gas business will be negatively affected.

Long-term debt, including the current portion of long-term debt, was as follows:

(euro million) |  | Dec. 31, 2010 |  | June 30, 2011
i | i |  | i |

i | i | Long-term portion | i | Short-term portion | i | Total | i | Long-term portion | i | Short-term portion | i | Total

|  | 20,305 |  | 963 |  | 21,268 |  | 22,021 |  | 1,216 |  | 23,237

Long-term debt, including the current portion of long-term debt, of euro 23,237 million (euro 21,268 million at December 31, 2010) increased by euro 1,969 million.
The increase was essentially due to the balance of repayments (euro 1,057 million) and new proceeds (euro 3,050 million), partially offset by a decrease of euro 89 million for currency translation differences and translation differences arising on debt denominated in foreign currency taken on by euro-reporting subsidiaries.
Eni entered into long-term borrowing facilities with the European Investment Bank which were subject to the maintenance of certain performance indicators based on Eni’s consolidated financial statements or the maintenance of a minimum level of credit rating. According to the agreements, should the Company fail to comply with maintenance of a minimum credit rating, new guarantees would be provided to be agreed upon with the European Investment Bank. At December 31, 2010 and June 30, 2011, the amount of short and long-term debt subject to restrictive covenants was euro 1,685 million and euro 1,875 million, respectively. A possible non-compliance with those covenants would be immaterial to the Company’s ability to finance its operations. As of the balance sheet date, Eni was in compliance with those covenants.
Bonds of euro 13,355 million consisted of bonds issued within the Euro Medium Term Notes Program for a total of euro 10,547 million and other bonds for a total of euro 2,208 million.

Eni Condensed consolidated interim financial statements / Notes to financial statements

Provision for environmental risks of euro 3,058 million included a provision accrued in 2010 of euro 1,109 million in relation to a proposal filed by the Company to the Ministry of the Environment, Land and Sea on January 26, 2011, to enter into a global transaction on certain environmental issues as per Article 2 of Law Decree 208/2008 (see page 93 of Eni’s Annual Report 2010). Pursuant to the above mentioned legislation, the competent technical offices, in particular the Institute for Environmental Protection and Research (ISPRA) and the Evaluator Commission for investment supporting planning and management of environmental activities (COVIS), are reviewing the proposal.
Additions to provision for legal and other proceedings of euro 108 million comprised an adjustment amounting to euro 69 million following a sentence recently issued by the Court of Justice of the European Community in connection with an antitrust proceeding in the European sector of rubbers.

Fair value of non-hedging derivatives of euro 481 million (euro 328 million at December 31, 2010) referred to derivative contracts that do not meet the formal criteria to be designated as hedges under IFRS because they were entered into in order to manage the net business exposures in foreign currency exchange rates, interest rates and commodity prices.

Fair value of trading derivatives of euro 58 million (euro 16 million at December 31, 2010) related to derivatives entered by the Gas & Power segment consistently with the new risk management model for an active managing of margins.
Fair value of cash flow hedge derivatives amounted to euro 2 million (euro 157 million at December 31, 2010) pertained to the Gas & Power segment.
These derivatives were designated to hedge surpluses or deficits of gas to achieve a proper balance in gas portfolio. The effects of the evaluation at the fair value of cash flow hedge derivatives are given in Note 23 – Shareholders’ equity and Note 27 – Operating expenses.
Other liabilities of euro 1,963 million (euro 1,586 million at December 31, 2010) included advances received from Suez following the long-term supplying of natural gas and electricity of euro 1,099 million (euro 1,353 million at December 31, 2010) and advances received from gas customers who off-took lower quantities of gas than the contractual minimum quantity as provided by the relevant long-term sale arrangement, thus triggering the take-or-pay clause (euro 296 million).

Fair value of financial instruments
Information on the fair value of financial instruments is reported in the relevant notes.
The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique.

(a) |  | Level 1: quoted prices (unadjusted) in active markets for identical financial assets or liabilities;
(b) |  | Level 2: measurements based on the basis of inputs, other than quoted prices above, which, for assets and liabilities that have to be measured, can be observable directly (e.g. prices) or indirectly (e.g. deriving from prices);
(c) |  | Level 3: inputs not based on observable market data.

Financial instruments measured at fair value in the balance sheet as of at June 30, 2011, were classified as follows: (i) level 1, "Other financial assets held for trading or available for sale" and "Non-hedging derivatives – Future"; and (ii) level 2, derivative instruments different from "Future" included in "Other current assets", "Other non-current assets", "Other current liabilities" and "Other non-current liabilities". During the first half of 2011, no transfers were done between the different hierarchy levels of fair value.
More information about the amount of financial instruments valued at fair value are provided in Note 4 – Other financial assets held for trading or available for sale, Note 7 – Other current assets, Note 13 – Other non-current assets, Note 17 – Other current liabilities and Note 21 – Other non-current liabilities.

Unless otherwise indicated below, no provisions have been made for these legal proceedings as Eni believes that negative outcomes are not probable or because the amount of the provision cannot be estimated reliably.

1. Environment

Criminal proceeding

(i) |  | Eni SpA – Fatal accident Truck Center Molfetta – Prosecuting body: Public Prosecutor of Trani. On March 3, 2008, in the Municipality of Molfetta a fatal accident occurred that caused the death of four workers deputed to the cleaning of a tank car owned by the company FS Logistica, part of the Italian Railways Group. The tank was used for the transportation of liquid sulphur produced by Eni in the Refinery of Taranto and destined to the client company Nuova Solmine. Consequently, a criminal action commenced against certain employees of FS Logistica and of its broker "La Cinque Biotrans" and, under the provisions of Legislative Decree No. 231/2001, against the two above mentioned companies and the company responsible for the clean-up of the tank car – Truck Center. On October 26, 2009, the First Degree Court concluded that both the above mentioned persons and the three companies were guilty. Additionally, the documentation related to the trial was forwarded to the Public Prosecutor of Trani in order to ascertain the eventual responsibilities of Eni and Nuova Solmine employees in relation to the fatal accident and also to the Public Prosecutors of Taranto and Grosseto (competent for Nuova Solmine) in order to ascertain eventual irregularities in the procedures of handling and transporting liquid sulfur. Following the sentence, the Public Prosecutor of Trani commenced an investigation against a number of employees of Nuova Solmine and an employee of Eni’s Refining & Marketing Division, responsible for marketing liquefied sulphur. On April 14, 2010, the Judge for the Preliminary Hearings notified the Eni’s employee a request of extension of the preliminary investigations. On May 11, 2010, Eni SpA, eight employees of the company and a former employee were notified of closing of the investigation that objected the manslaughter, grievous bodily harm and illegal disposal of waste materials. A number of defendants filled defensive memoranda. The Public Prosecutor has removed three defendants and transmitted evidence to the Judge for preliminary investigations requesting to dismiss the proceeding. The Judge for preliminary investigation accepted the above mentioned request.
|  | In the hearing for the positions not dismissed of February 23, 2011, the Judge scheduled the hearing for the eventual admittance as plaintiffs of the Puglia Region, the Municipality of Molfetta and a relative of one of the victims (notwithstanding these counterparts haven’t been identified as parts potentially injured by the alleged crime by the Public Prosecutor).

|  | In the hearing of April 19, 2011, the Judge admitted as plaintiffs against the above mentioned persons all the parts, excluding the relative of one of the victims, whose position have been declared inadmissible lacking of cause of action.
|  | The Judge declared inadmissible all the requests in acting as plaintiff against Eni, under the provisions of Legislative Decree No. 231/2001 and of recent case law.
|  | The plaintiffs claimed the identification as civil responsible of Eni SpA and the persons that stand in trial on the proceeding. This request was accepted by the judge.
|  | Eni SpA and its indicted employees requested to stand a summary procedure. The request was accepted by the Judge at the preliminary hearing held July 22, 2011. The Judge scheduled the hearings of the summary procedure on November 2 and 18, 2011 and January 13, 2012. The Judge also resolved to deny that Eni be liable for civil responsibility at the summary procedure.

(ii) |  | Syndial SpA – Proceeding about the industrial site of Crotone. In 2010, the Public Prosecutor of Crotone started an inquiry about a landfill site located in the municipal area. The landfill site was taken over by Eni’s subsidiary in 1991 following the divestment of an industrial complex by Montedison. The landfill site had been filled with industrial waste from Montedison activities till 1989 and then no more waste was discharged there. Eni’s subsidiary started a plan to put on safety the landfill site. On May 3, 2011, the Public Prosecutor notified certain persons, including a number of managers of Eni’s subsidiaries, who took over the ownership of the landfill site in the course of the years that criminal investigations have commenced. The Public Prosecutor has charged the investigated persons with the alleged crimes of environmental disaster and poisoning of substances used in the food chain due to the circumstance that the landfill site was partially located under the seabed. In addition the Public Prosecutor has claimed the alleged crime of omitted clean-up of the area. The Public Prosecutor requested the performance of probationary evidence. The defending counsel filed memoranda claiming that Eni’s managers were non involved in the handling of the landfill site. Investigations are ongoing.
(iii) |  | Eni SpA – Industrial site of Praia a Mare. Based on complaints filed by certain offended persons, the Public Prosecutor of Paola started an enquiry about alleged diseases related to tumors which those persons contracted on the workplace. Those persons were employees at an industrial complex owned by a Group subsidiary many years ago. On the basis of the findings of independent appraisal reports, in the course of 2009 the Public Prosecutor resolved that a number of ex-manager of that industrial complex would stand trial. In the preliminary hearing held in November 2010, 189 persons entered the trial as plaintiff; while 107 persons were declared as having been offended by the alleged crime. The plaintiffs have requested that both Eni and Marzotto would bear civil liability. However, compensation for damages suffered by the offended persons has yet to be determined. Upon conclusion of the preliminary hearing, the Public Prosecutor resolved that all defendants would stand trial for culpable manslaughter, culpable injuries, environmental disaster and negligent conduct about safety measures on the workplace. The trial commenced on June 24, 2011. The next hearing is scheduled October 7, 2011.
(iv) |  | Syndial SpA – Porto Torres – Prosecuting body: Public Prosecutor of Sassari. In March 2009, the Public Prosecutor of Sassari (Sardinia) resolved to commence a criminal trial against a number of executive officers and managing directors of companies engaging in petrochemicals operations at the site of Porto Torres, including the manager responsible for plant operations of the Company’s fully-owned subsidiary Syndial. The charge involves environmental damage and poisoning of water and crops. In the preliminary hearing on July 17, 2009, the Province of Sassari, the Association Anpana (animal preservation) and the company Fratelli Polese Snc, situated in the industrial site, have been acting as plaintiffs. None of these parties claimed the identification of the civil responsible and the damage quantification that will be asked in a second step. The defense counsel of Syndial requested further time for the recognition of the proceeding plaintiffs and the verification of their right to institute proceedings. The defense counsel of Syndial filed a number of exceptions on the admissibility in acting as plaintiffs of the claimants; the Judge addressed the question in a hearing in February 2010. In this hearing the Judge, based on the exceptions issued by Syndial on the lack of connection between the action as plaintiff and the charge, denied that the claimants would act as plaintiff with regard to the serious pathologies related to the existence of poisoning agents in the marine fauna of the industrial port of Porto Torres; the Judge admitted as plaintiffs the Municipality of Sassari, the Environmental Association Anpana and the company Fratelli Polese Snc. The Judge also resolved that Syndial SpA, Polimeri Europa SpA, Ineos Vinyls and Sasol Italy SpA would bear civil liability. Then, the Judge based on the conclusions of the Public Prosecutor and memoranda filed by the defending counsels resolved that all defendants would stand trial before a jurisdictional body of the Italian criminal law which is charged with judging the most serious crimes. The hearing is scheduled on December 16, 2011.

In particular the homes and offices of an employee of Eni Zubair and a manager of Saipem were searched by the authorities. The accusation is of criminal conspiracy and corruption in relation with the activity of Eni Zubair in Iraq and of Saipem in the "Jurassic" project in Kuwait. The Public Prosecutor of Milan has associated Eni Zubair, Eni and Saipem with the accusations as a result of the alleged illicit actions of their employees, who have also been described as non loyal employees of Eni Group. The Eni Zubair employee resigned and the company, accepting the resignation, reserved the right to take action against the individual to defend its interests. Notwithstanding that the Eni group companies are associated with these accusations, Eni SpA and Saipem SpA also received, at the same time the search warrant was issued, a notification pursuant to the Legislative Decree No. 231/2001. While the minuting of the seizure, Eni SpA asserted the company had no involvement as all activities in Iraq are carried out by its subsidiary Eni Zubair.

4. Tax Proceedings

Eni SpA and Eni Adfin SpA

The Tax Authorities have denied certain cost deductions and assessed a greater value for the going concern transferred to Eni Insurance Ltd in 2007. The total claim amounted to euro 148.5 millions for taxes, penalties and interests. According to the guarantee issued in 2008, related to the sale of Padana Assicurazioni shares to Helvetia SV AG, this additional tax burden is to be charged to the seller companies: Eni SpA for 26.75% and its subsidiary Eni Adfin SpA for 73.25%. In July 2011, the two companies defined a transaction for the assessments related to fiscal years 2006 and 2007. The amount that will be paid as fine was accrued in a risk provision in the 2010 consolidated financial statements, with a not significant increase of the above mentioned provision performed subsequently. The definition of the transaction related to fiscal year 2005 is ongoing and the company considers adequate the related risk provision accrued.

Derivative financial instruments consisted of the following:

(euro million) |  | First half 2010 |  | First half 2011

Derivatives on exchange rate |  | (249 | ) |  | 192
Derivatives on interest rate |  | (87 | ) |  | 33
Derivatives on commodities |  | 5 |  |  |
|  | (331 | ) |  | 225

Net gain from derivatives of euro 225 million (net loss of euro 331 million in the first half of 2010) was primarily due to the recognition in the profit and loss account of the change in the fair value of those derivatives which cannot be recognized according to hedge accounting under IFRS as they were entered into for amounts equal to the net exposure to exchange rate risk and interest rate risk, and as such, they cannot be referred to specific trade or financing transactions. The lack of these formal requirements to qualify these derivatives as hedging instruments under IFRS also entailed the recognition in profit or loss of negative currency translation differences on assets and liabilities denominated in currencies other than functional currency, as this effect cannot be offset by changes in the fair value of the related instruments.

(euro million) |  | First half 2010 |  | First half 2011

Eni signs Memorandum with the Libyan NTC

Benghazi, August 29, 2011 – Eni and the Libyan National Transitional Council (NTC), which is recognized by Italy and the international community as a legitimate representative of the Libyan people, today signed a Memorandum that strengthens cooperation in Libya between the parties.

Under the terms of the Memorandum, Eni and NTC are committed to creating the conditions for a rapid and complete recovery of Eni's activities in Libya and to doing all that is necessary to restart operations on the Greenstream pipeline, bringing gas from the Libyan coast to Italy.

Furthermore, with reference to the joint declaration signed on May 31, 2011 by the Italian government and NTC, Eni has engaged in providing a first supply of refined petroleum products to NTC to contribute to the basic and most urgent needs of the Libyan population. Eni will also provide technical assistance to assess the state of facilities and energy infrastructure in Libya and to define the type and extent of operations required to safely restart activities.

Eni has been active in Libya since 1959 and is the largest foreign player in terms of hydrocarbon production. The Memorandum signed today represents, in this delicate time for Libya, confirmation of the robust relationship between Eni ans NTC, who are evaluating various possible forms of cooperation in order to ensure the timely resumption of operations in the oil & gas sector and to enhance the country's natural resources to benefit the Libyan people and in respect of the existing contract. Eni also provides NTC with humanitarian aids by supplying medical equipments.
