STATEMENT BY THE PERSONS RESPONSIBLE FOR THE 2011 FIRST-HALF FINANCIAL REPORT 59

STATUTORY AUDITORS' REVIEW REPORT ON THE 2011 HALF-YEAR FINANCIAL INFORMATION 61

1 MANAGEMENT REPORT

The GDF SUEZ Group delivered strong fi rst-half 2011 earnings despite persistently tough market conditions, with exceptionally warm weather both in France and Belgium and a continuing spread between gas and fuel prices amid a volatile, uncertain price environment.

Revenues came in at €45.7 billion, up 7.9% on a reported basis (2.7% on an organic basis) versus fi rst-half 2010. Revenue growth was powered by (i) the Group's strong international expansion, (ii) the consolidation of International Power in February 2011, (iii) sales growth at Global Gas & LNG – particularly for Exploration & Production and LNG businesses – and (iv) a strong performance by SUEZ Environnement.

EBITDA came in at €8.9 billion, a year-on-year increase of 8.2% on a reported basis (decrease of 1.1% on an organic basis). Reported EBITDA growth was driven by the contribution from International Power, the impact of facilities commissioned in all Group businesses – testifying to its successful investment program – as well as growth in environment businesses and an upturn in service businesses. Excluding the impact of weather conditions, EBITDA would have advanced on an organic basis.

Current operating income inched up 0.3% on a reported basis, squeezed by higher depreciation/amortization expenses and charges to provisions resulting from business combinations and facilities commissioned over the period. Current operating income was also affected by a one-off mark-to-market accounting impact related to the recognition of the International Power business combination.

Net income Group share totaled €2.7 billion for fi rst-half 2011. This fi gure was down on fi rst-half 2010, which had been boosted by a number of asset disposals and the remeasurement of previouslyheld interests in entities acquired as part of business combinations.

Cash generated from operations came in 8.0% higher year-on-year, at €8.7 billion, mirroring the increase in EBITDA.

Net debt stood at €40.7 billion at end-June 2011, down €2.1 billion on pro forma net debt at December 31, 2010 (including International Power). The fall in debt came on the back of strong cash fl ow generation and positive currency impacts totaling around €800 million. The net debt fi gure does not take into account the €1.1 billion payment received on July 12, 2011 for the sale of 25% of GRTgaz to the CDC/CNP consortium.

REVENUE AND EARNINGS TRENDS

Revenues for the Group came in at €45.7 billion in fi rst-half 2011, up 7.9% on fi rst-half 2010. On an organic basis (excluding changes in exchange rates and the scope of consolidation), revenues rose 2.7% year-on-year.

Changes in the scope of consolidation had a positive €2,239 million impact.

Additions to the scope of consolidation added €2,864 million to revenues, resulting mainly from the fi rst-time consolidation of International Power, the full consolidation of Agbar by SUEZ Environnement, the reorganization of activities previously carried out by the Group in partnership with Acea in Italy and the fi rsttime consolidation of Utilicom, Pro-Energie and Thion-Ne Varietur in the services segment.
Departures from the scope of consolidation represented €625 million and essentially concerned the sale of Adeslas (Agbar's health business) by SUEZ Environnement.

Changes in exchange rates had a marginal negative €47 million impact.

All of the Group's business lines reported an increase in their revenue contribution on both a reported and organic basis, with the exception of Energy France, hit by a signifi cant fall in sales due mainly to particularly warm weather over the period as well as an unfavorable basis for comparison on the back of cold weather conditions in the fi rst half of 2010.

EBITDA moved up 8.2% to €8.9 billion. Stripping out the impact of changes in exchange rates and the scope of consolidation, EBITDA slipped back 1.1% on an organic basis.

Changes in Group structure had a net positive impact of €754 million on EBITDA.

Additions to the scope of consolidation added €802 million to EBITDA and mainly concerned the transactions described above in Energy Europe & International (including €552 million related to International Power and Hidd Power), SUEZ Environnement and Energy Services.
Departures from the scope of consolidation represented €48 million and concerned primarily the sale of Adeslas in Spain.

Changes in exchange rates had a marginal €7 million positive impact.

EBITDA retreated €89 million, or 1.1%, on an organic basis, without adjusting for weather conditions:

Energy France reported a sharp 18.5% fall in EBITDA on an organic basis, with its electricity sales and production activities signifi cantly impacted by exceptionally warm (sales of natural gas) and dry (poor hydro conditions) weather in the fi rst half;
EBITDA for GDF SUEZ Energy Benelux & Germany was also down on an organic basis, falling 10.4% on the back of narrower electricity margins (lower prices), a negative climatic impact on gas sales, and the non-recurrence of one-off items which had boosted results in fi rst-half 2010 (writeback of provisions for taxes on idle plants);
EBITDA for GDF SUEZ Energy Europe suffered the same trend as described above for GDF SUEZ Energy Benelux & Germany, falling 13.9% in the period due to tough market conditions in Europe (prices, volumes, weather, regulations) and to the nonrecurrence of the one-off items that had boosted fi rst-half 2010 fi gures;
International Power in contrast reported vigorous 25.7% organic EBITDA growth, powered by strong operating results from its businesses in Latin and North America;
Global Gas & LNG reported a return to organic EBITDA growth (up 3.1%), as a good performance from Exploration & Production activities (volume impacts resulting from facilities recently commissioned and positive price impacts on Brent crude) and LNG operations (increase in the re-routing of cargoes) helped offset the adverse impact of gas/oil price spreads as well as the drop in sales to European Key Accounts;
Infrastructures saw EBITDA fall 8.9%. The commissioning of the Fos Cavaou LNG terminal, and a rise in transportation and distribution costs failed to offset the impacts of exceptionally warm weather in the fi rst half of 2011;
Energy Services posted 4.6% EBITDA growth, refl ecting its ability to capitalize on the upside of recovery in certain sectors;
SUEZ Environnement reported robust organic growth in its businesses (EBITDA up 6.9%), spurred by rising volumes and prices for recovered secondary raw materials, vigorous growth for Agbar and advances in its international business excluding cost overruns on the Melbourne project.

Current operating income remained stable year-on-year, at €5.2 billion. Stripping out the impact of changes in exchange rates and the scope of consolidation, current operating income fell 6.3% on an organic basis. Current operating income fell more than EBITDA, due to an increase in depreciation/amortization expenses and charges to provisions as a result of facilities commissioned in the period. The amortization expense comprised in addition a negative €90 million non-recurring mark-to-market accounting impact arising on the consolidation of International Power.

In the six months to June 30, 2011, Energy France contributed revenues of €7,401 million, down 8.5% on the prior-year period. This refl ects:

a positive €8 million impact resulting from changes in the scope of consolidation (impact of second-half 2010 acquisitions in the Housing Services segment);
a negative €1,650 million volume impact, essentially due to the fall in gas sales;
a positive €944 million price effect, refl ecting the impact of the rise in gas prices in April and July 2010;
a positive €10 million impact resulting from miscellaneous items.

Gas sales totaled 131 TWh, a decline of 24%, or 42 TWh, on fi rsthalf 2010. This decline chiefl y refl ects an adverse climatic impact of 30.5 TWh (the fi rst six months of 2011 were particularly warm, whereas the fi rst six months of 2010 had been particularly cold), a contracting market on a constant climatic basis, and, to a lesser extent, the loss of certain customers to other suppliers. At end-June 2011, GDF SUEZ nevertheless continued to hold around 88% of the retail market and some 70% of the business market.

Electricity sales fell to 18.3 TWh from 18.9 TWh in fi rst-half 2010. Growth in the retail portfolio (which now has more than one million customers for a total number of 1,220,000 retail and business customer sites) was offset by poor hydro conditions and a drop in sales on wholesale markets.

Electricity production fell 9%, as very dry weather in spring 2011 more than offset the impact of the development of wind farms and the commissioning of new thermal power plants in 2010.

BUSINESS TRENDS

EBITDA shrank €134 million, mainly on the back of a fall in sales (due to weather and hydro conditions). A tariff shortfall of €73 million was also reported in fi rst-quarter 2011, compared to €58 million in fi rst-half 2010.

Current operating income fell €32 million more than EBITDA, refl ecting higher depreciation and amortization charges relating to the development of production assets.

Price trends

Public distribution tariffs

The table below shows the average change in public distribution tariffs adopted since 2009. Tariffs were stable between July 2010 and March 2011. The sharp rise in gas supply costs led to an increase of €2.45/MWh on April 1, 2011.

2.2.2 GDF SUEZ Energy Benelux & Germany

Revenues for the Energy Benelux & Germany business area came in at €7,130 million for fi rst-half 2011, down 3% on fi rst-half 2010. Excluding the impact of changes in Group structure and, in particular, the proportionate consolidation of Stadtwerke Gera in Germany, revenues fell 2.9% on an organic basis versus fi rst-half 2010.

Electricity sales

Electricity volumes sold fell 11.7% to 57.8 TWh, while revenues dropped €283 million.

In Belgium and Luxembourg, electricity sales edged up €28 million, or 0.8%, despite a sharp 7.0% (2.6 TWh) downturn in volumes.

The decline in volumes was recorded in Belgium on sales to business segments. These shrank by 2.5 TWh following customer attrition representing 1.8 TWh and a fall in consumption.
Sales to retail customers contracted by 2%, or 0.2 TWh, due equally to customer attrition and a fall in consumption.
Sales to the wholesale sector remained virtually stable, up 0.1 TWh.
The impact of these lower volumes was offset by an increase in average prices in all segments except wholesale. Almost half of this rise stemmed from the increase in transportation and distribution tariffs.

Electricity sales in the Netherlands were down €121 million (15.8%) and by 1.4 TWh (12.1%).

The decline in electricity sales was reported chiefl y on:

the wholesale market (down €53 million/0.6 TWh), where losses were driven by lower volumes produced due to declining margins on gas-fi red power plants;
the resellers market, which contracted €51 million (0.8 TWh), due to a fall in the volumes sold to two major resellers.

Average prices for all segments dropped €2.8 per MWh.

Sales of electricity in Germany rose €46 million (7.4%) and by 0.5 TWh (4.9%).

This increase was partly attributable to the proportionate consolidation of Stadtwerke Gera (positive impact of €17.4 million).
A rise in volumes sold principally to new reseller customers accounted for the remainder of the increase. However, the average price on business segments fell €5.1 per MWh.

Outside the Benelux & Germany region, sales were down €245 million (49.4%) and 4.1 TWh (50.8%).

Sales in France on the resellers market retreated €105 million, refl ecting the sharp 1.2 TWh fall in volumes sold to our two largest reseller customers.
Hardly any electricity was sold to the United Kingdom in the period (versus 2.6 TWh sold in fi rst-half 2010).

Gas sales

Revenues from gas sales edged up 0.7%, even though volumes sold fell 5.9 TWh, or 11.2%. The decline in volumes was therefore fully offset by the rise in sales prices.

Different weather conditions in fi rst-half 2011 compared to fi rsthalf 2010 account for the fall in volumes sold. Volumes lost due to milder temperatures were estimated at 6.2 TWh in the six months to June 30, 2011.

Sales price rises were especially signifi cant in Belgium (average prices per MWh up 22.4%, mostly on commodities). This refl ects trends in the gas market and the index mechanisms used for contracts with retail customers and small and mid-sized businesses. However, average prices dipped slightly in Germany and the Netherlands.

EBITDA for the GDF SUEZ Energy Benelux & Germany business area totaled €1,151 million in fi rst-half 2011, a fall of 12.5% on fi rst-half 2010. On an organic basis, EBITDA dropped 10.4% year-on-year.

Changes in the scope of consolidation had a negative €28 million impact on EBITDA.

The net impact of new facilities commissioned was €69 million, relating mainly to the new Flevo plant in the Netherlands and the Knippegroen unit (Sidmar) in Belgium.

Changes in the price of commodities in the region accounted for much of the remainder of the decline. EBITDA was also hit by the non-recurrence of one-off items which had boosted performance in fi rst-half 2010.

Current operating income for the business area came in at €813 million versus €1,065 million in fi rst-half 2010. Besides the decline in EBITDA, current operating income was also hit by higher depreciation and amortization charges as a result of the planned early closure of conventional power plants in Belgium (impact of the newly commissioned Flevo and Sidmar plants).

2.2.3 GDF SUEZ Energy Europe

The GDF SUEZ Energy Europe business area contributed €3,527 million in revenues in fi rst-half 2011, up 6.5% on a reported basis compared with one year earlier.

Changes in exchange rates had a marginal €2 million positive impact in Central and Eastern Europe, while changes in the scope of consolidation added €62 million to revenues as a result of the reorganization early in the year of activities previously carried out by the Group in partnership with Acea in Italy.

Revenues grew €153 million or 5.0% year-on-year on an organic basis, refl ecting:

Southern Europe (up €100 million), which was boosted by development plans resulting in the commissioning of the Héron 2 power plant in Greece in August 2010, and by an increase of 333,000 in the number of customers for its sales operations in Italy. The region also benefi ted from a positive volume impact on virtual capacity purchase contracts in Italy and from a positive price effect on regulated electricity tariffs;
a 1.8 TWh fall in electricity production sold, which drove down revenues in Spain and Portugal by €59 million;
revenues in Central and Eastern Europe, which were up by €112 million on the back of higher tariffs in Hungary and Slovakia and an increase in volumes sold and distributed in Romania and Slovakia (up 1.5 TWh and 0.7 TWh, respectively).

EBITDA for GDF SUEZ Energy Europe came in at €580 million for fi rst-half 2011, down €24 million, or 3.9%, based on reported fi gures. On an organic basis, EBITDA for the business area declined €82 million, or 13.9%, and is analyzed below:

Central and Eastern Europe reported negative organic EBITDA growth of €54 million, due chiefl y to the slowdown in gas sales activities in Slovakia and Romania, hit by the squeeze on supply costs. Electricity production operations contracted in Poland following diffi culties with the local coal supply, and in Hungary further to the fall in volumes of ancillary services;
Italy and Greece saw EBITDA rise €14 million, spurred by the development of sales activities and by the contribution of the Héron 2 power plant in Greece, which offset lower prices and ancillary services;
Spain and Portugal reported negative organic EBITDA growth of €58 million, refl ecting the non-recurrence of one-off indemnities received in fi rst-half 2010 in respect of a power plant under construction, and a signifi cant negative volume impact despite a good performance on ancillary markets (better prices captured).

Current operating income for the business area was down 22.6% on an organic basis, at €353 million in fi rst-half 2011. The downward trend was chiefl y driven by the same factors as those described above for EBITDA.

2.2.4 International Power

* A portion of these costs has not been allocated.

Revenues for International Power totaled €7,601 million, advancing 46% on a reported basis and 12% on an organic basis compared to fi rst-half 2010. In addition to the consolidation of the International Power assets acquired, which had a positive €1.9 billion impact on revenues, sales were fuelled by growth in three business areas – Middle East, Turkey & Africa, Latin America, and UK & Other Europe. Sales growth was driven, in particular, by the commissioning of the Estreito plant in Brazil, the Bahia Las Minas coal conversion project and the Dos Mares plant in Panama, and the Elecgas plant in Portugal.

First-half EBITDA for the segment rose even more sharply than revenues, progressing 72% on a reported basis and 26% organically to reach €2,056 million. The Latin America and North America business areas showed the strongest margin growth.

Current operating income came in at €1,287 million, surging 56% on a reported basis and 28% based on organic fi gures following the recognition at fair value of the International Power assets acquired.

2.2.4.1 International Power – Latin America Area

Revenues for the International Power – Latin America business area totaled €1,843 million for first-half 2011, up 26.7% on a reported basis and 23.2% (or €337 million) on an organic basis compared to first-half 2010.

Revenues include the €53 million impact of changes in the scope of consolidation resulting from the controlling interest acquired in electricity operations in Chile in January 2010 (E.Cl) and in the Mejillones LNG terminal in second-half 2010. Changes in exchange rates accounted for a marginal €1 million negative impact.

Electricity sales were stable, representing 24.4 TWh in the six months to June 30, 2011. This fi gure includes the negative impact resulting from the nationalization of the Corani plant in Bolivia in May 2010. Gas sales climbed 4.0 TWh to 7.6 TWh, due chiefl y to the commissioning of the Mejillones LNG terminal in Chile.

Organic revenue growth results chiefl y from:

Brazil, with higher average sales prices thanks to the combined impact of new contracts replacing contracts expired and of infl ation;
Chile, thanks to the commissioning of the Mejillones LNG terminal in April 2010 as well as higher average sales prices, with E.Cl benefi ting from a rise in the coal index and an increase in volumes sold (new customer);
Panama, which saw average sales prices increase as a result of rising coal prices and the positive impact of the newly commissioned Dos Mares facility.

EBITDA for the business area was €207 million higher at €863 million, representing organic growth of €197 million, or 29.6%:

in Brazil, new contracts negotiated at higher prices, infl ation and a rise in hydro electricity production (following the commissioning of Estreito) drove growth in margins;
in Chile, EBITDA growth refl ected the commissioning of the Mejillones LNG terminal;
in Panama, the Bahia Las Minas plant benefi ted from compensation for the delay in the plant's conversion to coal and from rising margins. EBITDA for the Panama business was also boosted by the fi rst stage in the commissioning process of the Dos Mares run-of-river facility.

Current operating income for the business area came in at €662 million for fi rst-half 2011, up €142 million on an organic basis. The upward trend results from the same factors as those described above for EBITDA.

2.2.4.2 International Power – North America Area

Revenues for the International Power – North America business area came in at €2,355 million for fi rst-half 2011, up €273 million, or 13.1%, year-on-year based on reported fi gures, and €34 million, or 1.7%, on an organic basis. Changes in exchange rates had a negative €102 million impact, resulting from the depreciation in the US dollar. Additions to the scope of consolidation added €341 million to revenues, refl ecting the consolidation of International Power assets.

Sales of electricity totaled 38.1 TWh, up 2.2 TWh on an organic basis. The rise in electricity sales is due chiefl y to a strong performance from the retail business of GDF SUEZ Energy Resources North America, which supplies electricity to commercial and industrial customers. Volumes for these sales jumped 17.5% to 17.0 TWh, while revenues moved up €85.1 million on an organic basis. These increases were partially offset by a fall-off in the Production business, which saw revenues contract €44 million on an organic basis due to mixed price effects on its different markets and volumes sold retreating 0.3 TWh (12.9 TWh in all over the period).

The contribution from natural gas sales slipped 1.4 TWh on an organic basis, to 32.1 TWh. Besides the volume impact, revenues were also hit by a rise in average prices after hedging in the LNG business (1).

First-half EBITDA for the North America business area totaled €487 million, up €186 million based on reported fi gures. Excluding a negative €14 million currency impact (due chiefl y to the depreciation of the US dollar) and positive €112 million impact of changes in the scope of consolidation (consolidation of International Power assets), the business area's organic growth came in at 30.6%, or €88 million.

This stems chiefl y from:

the LNG business (up €58 million), boosted by higher prices following the re-routing of cargoes towards South Korea and Spain, for example;
a strong performance from the retail energy sales business (up €18 million), helped by lower volatility and purchase prices.

Electricity production operations inched up €9 million. This increase refl ects an insurance indemnity collected, a good performance by Astoria I (strong demand and wider spreads) and a rise in electricity produced by wind farms. The increase was partly offset by a fall in hydro production (low rainfall), the end of certain profi table longterm contracts, and the unavailability of some of our power plants.

Current operating income for the business area came in €94 million higher on an organic basis, at €259 million for fi rst-half 2011. The reasons for this increase are the same as those described above for EBITDA.

2.2.4.3 International Power – UK & Other Europe Area

The International Power – UK & Other Europe business area contributed revenues of €1,565 million in fi rst-half 2011, up 132.5% year-on-year on a reported basis. Changes in exchange rates had a positive €2 million impact over the period, while changes in the scope of consolidation added €749 million to the revenue fi gure, resulting mainly from the consolidation of International Power assets within the GDF SUEZ Group at the beginning of the year.

On an organic basis, revenues gained 21.0% on fi rst-half 2010, powered chiefl y by sales activities and particularly the gas segment, with volumes up 1.8 TWh, along with a positive price impact.

EBITDA for the business area was up €232 million based on reported fi gures, to €287 million and down €7 million, or 11.9%, on an organic basis, on the back of a 3.7 TWh fall in electricity volumes produced due to depressed market prices.

The business area's current operating income amounted to €106 million in fi rst-half 2011, down 61.9% on an organic basis. As well as the factors which also affected EBITDA, current operating income was hit by higher depreciation/amortization expenses and charges to provisions.

2.2.4.4 International Power – Middle East, Turkey & Africa Area

The International Power – Middle East, Turkey & Africa business area saw fi rst-half revenues surge 78.4% on a reported basis, up to €578 million in fi rst-half 2011, buoyed by the consolidation of International Power assets and the full consolidation of the Al Hidd power plant in Bahrain. Taking into account the negative €19 million currency impact (stemming chiefl y from changes in the euro/US dollar exchange rate), organic growth came in at €112 million, or 36.8%.

This performance was led mainly by a €50 million rise in electricity sales reported by Baymina, a €20 million increase in gas sales by Izgaz in Turkey and by the operations and maintenance business in Oman.

The business area's electricity sales rose 11.5 TWh to 15.4 TWh, due mainly to changes in the scope of consolidation (consolidation of International Power assets, including the resulting full consolidation of Al Hidd). Sales of natural gas edged up 0.6 TWh to 2.3 TWh.

EBITDA for the business area came in at €153 million for fi rst-half 2011, up €51 million, or 49.5%, on a reported basis. Excluding the impact of changes in the scope of consolidation, organic EBITDA fell 13.1%, or €13 million, due chiefl y to a fall in development fees.

(1) Sales of natural gas including intragroup services came in at 42.7 TWh, up 8.4 TWh on an organic basis.

Current operating income for the fi rst half was down €17 million based on organic fi gures, at €115 million. The reasons for the downturn are the same as those explained above for EBITDA.

2.2.4.5 International Power – Asia

Revenues for the International Power – Asia business area climbed 20.7% to €811 million based on reported fi gures. Including the positive €11 million impact of gains in the Singapore dollar, changes in the scope of consolidation resulting from the consolidation of International Power assets, and the proportionate consolidation of gas distribution assets in Thailand, organic revenue growth came in at 1.1% or €8 million.

The growth performance was driven chiefl y by Thailand (up €19 million) further to the commissioning of the CFB3 coal power plant, despite a 0.3 TWh drop in volumes sold in Singapore.

EBITDA for the business area totaled €165 million for fi rst-half 2011, a rise of €49 million based on reported fi gures. After stripping out the positive €2 million currency impact and the positive €41 million impact of changes in the scope of consolidation, EBITDA edged up €6 million.

In Thailand, the growth momentum provided by Glow's CFB3 unit was offset by adverse weather conditions in Laos.
In Singapore, Senoko reported a €10 million rise in EBITDA in fi rst-half 2011, buoyed by margin growth on sales agreements with industrial customers and market opportunities over the last two months of the period.

Current operating income for the business area came in at €123 million for the six months to June 30, 2011, creeping up 2.5% based on organic fi gures. The reasons for this trend are the same as those described above for EBITDA.

2.2.4.6 International Power – Australia

First-half revenues for the International Power – Australia business area came in at €449 million, refl ecting the contribution of International Power assets. Electricity sales totaled 10.5 TWh.

The business area's contribution to EBITDA (€162 million) and current operating income (€77 million) was derived wholly from new International Power assets, i.e., from changes in Group structure.

2.3 GLOBAL GAS & LNG

In millions of euros	First-half 2011	First-half 2010	% change (reported basis)
BUSINESS LINE REVENUES	11,171	10,714	4.3%
REVENUE CONTRIBUTION TO GROUP	4,868	4,520	7.7%
EBITDA (A)	1,177	1,146	2.7%
Depreciation, amortization and provisions (B)	(571)	(539)
Share-based payment (C)	(2)	(2)
CURRENT OPERATING INCOME = A + B + C	604	605	-0.3%

Total first-half revenues for the Global Gas & LNG business line, including intragroup services, climbed 4.3% year-on-year based on reported fi gures, to €11,171 million.

The contribution of the business line to Group revenues was €4,868 million for fi rst-half 2011, up €348 million (7.7% on a reported basis) compared to first-half 2010.

First-half revenues were largely sustained by growth in Exploration & Production sales, the LNG business, and sales of the Gas Supplies business unit, which offset the decline in sales to European Key Accounts.

The rise in the business line's revenue contribution reflects mainly:

an increase in short-term sales after price hedging, in a market characterized by strong price infl ation (70% rise in average NBP prices, from €13.2/MWh in fi rst-half 2010 to €22.4/MWh in fi rsthalf 2011), with volumes up to 50.6 TWh (1) in the period versus 44.4 TWh one year earlier;
a 7.0 TWh increase in external LNG sales, to 19.4 TWh (21 cargoes) in fi rst-half 2011 versus 12.4 TWh (13.5 cargoes) in fi rst-half 2010, and the impact of spiraling commodity prices;

⁽¹⁾ Including sales to other operators.

⁽²⁾ Including three cargoes sold to a proportionally consolidated (50%) Chilean entity, which corresponds to 1.5 cargoes of external sales.

a contraction of 13.2 TWh in natural gas sales in the European Key Accounts portfolio – down from 86.4 TWh in fi rst-half 2010 to 73.2 TWh in fi rst-half 2011, essentially attributable to lower portfolio volumes in a fi ercely competitive environment;
Exploration & Production revenue growth, spurred mainly by a combination of higher average Brent crude prices (up 32% or €19.1/boe, from €60.3/boe in fi rst-half 2010 to €79.4/boe in fi rst-half 2011) and average NBP prices (up 70% or €9.2/MWh), and by the increase in the total hydrocarbon production (up 4.2 MMboe including a 2.1 MMboe contribution) owing to the commissioning of new oil fi elds in Norway (mainly Gjoa).

EBITDA for the Global Gas & LNG business line totaled €1,177 million for the six months to June 30, 2011 compared to €1,146 million in fi rst-half 2010. This represents a rise of €31 million, or 2.7%, based on reported fi gures. Advances in the Exploration & Production business spurred by the commissioning in late 2010 of the Gjoa and Vega oil fi elds in Norway and by the rise in commodity prices in the period, coupled with an improved performance from the LNG business, offset the adverse impact of gas/oil price spreads in the period and lower sales to European Key Accounts.

Current operating income came in at €604 million, on a par with fi rst-half 2010.

2.4 INFRASTRUCTURES

In millions of euros	First-half 2011	First-half 2010	% change (reported basis)
BUSINESS LINE REVENUES	2,949	3,085	-4.4%
REVENUE CONTRIBUTION TO GROUP	691	587	17.7%
EBITDA (A)	1,669	1,832	-8.9%
Depreciation, amortization and provisions (B)	(582)	(580)
Share-based payment (C)	(2)	(2)
CURRENT OPERATING INCOME = A + B + C	1,086	1,250	-13.2%

Total revenues for the Infrastructures business line including intragroup services came in at €2,949 million, down 4.4% on fi rsthalf 2010 due mainly to milder weather conditions in the period and lower storage capacity sales in France.

The decline in the total revenue fi gure is due to a 38.0 TWh fall in volumes transported by GrDF, refl ecting milder weather conditions than in fi rst-half 2010. The decline was partially offset by:

the start-up of commercial operations at Fos Cavaou, representing 20% of its capacity at April 1, 2010 and 100% as of November 1, 2010;
new transportation rates in France, which were raised 3.9% as of April 1, 2010 and 2.9% as of April 1, 2011;
a 0.8% increase in the rate for accessing distribution infrastructure as from July 1, 2010.

The contribution of the business line to Group revenues was €691 million, 17.7% higher than in the six months to June 30, 2010.

The increase in the contribution reflects:

the growth of transportation, storage and terminalling services on behalf of third parties due to an increasingly deregulated market;
the start-up of commercial operations at the Fos Cavaou LNG terminal.

EBITDA for the Infrastructures business line totaled €1,669 million for the period, down 8.9% on fi rst-half 2010 due chiefl y to the fall in revenues.

Current operating income for the business line came in 13.2% lower year-on-year at €1,086 million, in line with EBITDA trends.

2.5 ENERGY SERVICES

In millions of euros	First-half 2011	First-half 2010	% change (reported basis)
REVENUES	7,087	6,693	5.9%
EBITDA (A)	540	482	12.1%
Depreciation, amortization and provisions (B)	(144)	(144)
Net disbursements under concession contracts/share-based payment (C)*	(19)	(6)
CURRENT OPERATING INCOME = A + B + C	377	332*	13.6%

* Including a non-recurring expense of €15 million relating to the renewal of the Société Monégasque d'Électricité et de Gaz concession.

The Energy Services business line delivered revenues of €7,087 million for the period, up 2.4% on an organic basis compared to first-half 2010.

In France, revenues for service activities (Cofely France) remained stable (down 0.2%, or €3 million, on an organic basis), with the positive impact of commercial development and improving energy prices offsetting adverse weather conditions. Installation and maintenance activities delivered organic growth of 8.9%, or €160 million, thanks to revenue gains totaling 4.6% for Inéo, 14.4% for the Environmental and Refrigeration Engineering area, and 11.4% for Endel.

Belgium and the Netherlands reported organic growth of 3.9% (€30 million) and 8.5% (€44 million), respectively. In Belgium, this trend refl ects a good level of new orders in installation businesses as well as robust commercial development. In the Netherlands, the sales uptrend has picked up pace since the last quarter of 2010, as production began quickly on major new orders, buoying operations in the fi rst few months of 2011.

Tractebel Engineering reported stable organic growth despite further gains in the energy sector, held back by the lack of infrastructure projects and low orders in international subsidiaries, particularly in Europe.

Excluding France and Benelux, organic revenues for the business line declined 4.1% (€27 million) in northern Europe, with advances in Austria and Eastern European countries offsetting a downturn in the UK, Germany and Switzerland. Revenues dropped 7.9%, or €56 million, in southern Europe, driven chiefl y by Italy due to lower volumes of energy sales (adverse weather conditions, drop in fuel sales and early stoppage of a cogeneration plant) and building work, and by Spain, where the number of new projects remains very low. The International Overseas business unit delivered organic revenue growth of 4% (€10 million), buoyed by good rainfall, the ramp-up of production at the Prony Energies plant and the start-up of the Solaris photovoltaic unit in Reunion.

EBITDA for the Energy Services business line came in at €540 million, up 4.6% on an organic basis. This testifi es to its ability to capitalize fully on the recovery in certain sectors, even though the economic climate remains tough for its activities in most European countries.

All of the business areas reported strong organic EBITDA growth except Cofely France, hit by adverse weather conditions.

In France, service activities were affected by adverse weather conditions at the beginning of the year and pressure on margins when renewing contracts. Installation revenues continued to improve, spurred by a sharp rise in activity for most of its businesses.

Business diversifi cation and a strong sales momentum in Belgium helped lift performance despite a decline in Oil & Gas activities. In the Netherlands, the new organization and efforts to optimize overheads drove a recovery in margins and profi tability amid an upturn in sales.

Tractebel Engineering continued to put in an excellent performance, posting profi tability gains amid more stable business levels.

Following the consolidation of Utilicom as of April 1, 2010 and ProEnergie as of October 1, 2010, the International North business unit delivered revenue growth on both a reported and organic basis, lifted by a good performance from Germany, Austria and Eastern European countries.

The International South business unit had to contend with a particularly tough economic climate in Italy and Spain. Italy nevertheless delivered organic EBITDA growth on the back of gains relating to the early withdrawal from a cogeneration contract. Portugal also reported organic EBITDA growth.

BUSINESS TRENDS

EBITDA for the International Overseas business rose sharply on an organic basis, both for the unit's traditional businesses – particularly in New Caledonia – and in businesses in the Pacifi c region recently transferred by Endel.

In line with EBITDA trends, current operating income for the Energy Services business line jumped 6.5% on an organic basis to €377 million from €332 million in fi rst-half 2010.

2.6 SUEZ ENVIRONNEMENT

In millions of euros	First-half 2011	First-half 2010	% change (reported basis)
REVENUES	7,373	6,593	11.8%
EBITDA (A)	1,232	1,042	18.2%
Depreciation, amortization and provisions (B)	(529)	(477)
Net disbursements under concession contracts/share-based payment (C)	(142)	(128)
CURRENT OPERATING INCOME = A + B + C	561	437	28.6%

Revenues for SUEZ Environnement came in at €7,373 million for fi rst-half 2011, up 11.8% on 2010. Based on organic fi gures, revenues climbed 9.2%. All three operating segments contributed to revenue growth. Waste Europe saw revenues improve 10.3%, buoyed by upbeat waste sorting and recycling activities on the back of rising volumes and high raw material prices. The International segment reported 11.7% revenue growth, driven by billings on several major projects in Latin America and Asia (Melbourne), along with robust volume and price momentum across all regions. Revenues for the Water Europe segment rose 4.3%, powered by the dynamic volume/price momentum at Agbar in Chile and by more favorable conditions in France.

EBITDA grew 6.9% year-on-year on an organic basis, to €1,232 million, refl ecting an uptrend in business and the ramp-up of the cost-cutting program and synergies within Water Europe (up 9.5%); favorable price and volume impacts, and to a lesser extent, one-off impacts in Waste Europe (up 9.9%); and a decline in the International business (down 5.7%) due to cost overruns on the Melbourne project, mostly offset by good business levels in water and waste businesses in Asia/Pacifi c and North Africa/Middle East.

Total year-on-year growth in current operating income (up 28.6% versus fi rst-half 2010) was buoyed by the same operating fundamentals as described above for EBITDA, and by a slower rise in depreciation and amortization charges thanks to a tight rein on investments.

The operating performance of the business line for 2011 is presented in SUEZ Environnement's management report.

2.7 OTHER

In millions of euros	First-half 2011	First-half 2010	% change (reported basis)

CURRENT OPERATING INCOME = A + B + C	(184)	(187)	1.9%

OTHER INCOME STATEMENT ITEMS

The €27 million rise in fi rst-half EBITDA for the "Other" business line results primarily from one-off items, since the intrinsic performance of head offi ce divisions remained broadly in line with the performance in fi rst-half 2010.

Current operating income inched up just €3 million, due to the positive one-off impact in fi rst-half 2010 of certain bonus share plans accounted for in accordance with IFRS 2.

3 OTHER INCOME STATEMENT ITEMS

NET INCOME	3,519	4,145	-15.1%
Non-controlling interests	781	581
NET INCOME GROUP SHARE	2,738	3,565	-23.1%

Income from operating activities came in at €5,664 million, representing a decrease on fi rst-half 2010 due mainly to the positive impact of business combinations and other one-off items in 2010.

Changes in the fair value of commodity hedging instruments had a negative €95 million impact on income from operating activities (refl ecting the impact of transactions not eligible for hedge accounting), compared with a negative impact of €48 million in fi rsthalf 2010. This results primarily from a negative price impact on hedges of power and gas sales due to increases in the underlying indices since December 31, 2010.

Income from operating activities was also affected by:

asset impairment losses in the amount of €63 million, with no individual impairment loss being material;
restructuring costs of €51 million, including costs relating to the implementation of the International Power combination and

operating synergies (€19 million) and costs incurred to adapt to the economic environment in the Energy Services business line (€15 million);

• "Changes in scope of consolidation" (gains and losses on the disposal of consolidated equity interests or on the remeasurement of previously-held interests in accordance with the revised IFRS 3) totaling €592 million (€1,216 million in the fi rst half of 2010), primarily refl ecting the €425 million gain attributable to the remeasurement at fair value of the Group's interest in the Flemish inter-municipal companies further to the Group ceasing to exercise signifi cant infl uence over these entities and to the resulting change in consolidation method. It also includes the capital gains on the disposal of a portion of the share capital of the inter-municipal companies in the Walloon region (€83 million) and the disposal of equity interests in Noverco (€28 million);

• other non-recurring items, which totaled €51 million for the fi rst six months of 2011 (€197 million in fi rst-half 2010), and mainly include €39 million in capital gains on the disposal of property rights in the SUEZ Environment business line.

The net fi nancial loss for fi rst-half 2011 totaled €1,075 million, compared to a net loss of €1,070 one year earlier. The rise in net interest expense, resulting from the increase in average net debt compared to the same year-ago period, was offset by the positive changes in the fair value of economic currency and interest rate hedges.

The effective tax rate adjusted for disposal gains and losses came out at 34.1% in the period under review versus 29.8% in the fi rst half of 2010. The increase in the effective tax rate resulted primarily from:

• the increase in the proportion of income generated by Exploration & Production entities whose tax rate exceeds 50%;

the increase in the tax rate from 50% to 62% at end-March 2011 on Exploration & Production activities in the United Kingdom, resulting in a non-recurring deferred tax expense;
the provision set aside at June 30, 2011 in respect of the tax relating to Belgian nuclear activities.

Share in net income of associates advanced €112 million compared to the fi rst half of 2010, chiefl y due to changes in scope of consolidation owing to the fi rst-time consolidation of International Power.

Non-controlling interests in net income totaled €781 million. The €200 million increase in this item refl ects the consolidation of International Power entities.

4 CHANGES IN NET DEBT

At June 30, 2011, net debt stood at €40.7 billion, up €6.8 billion on end-December 2010 (€33.8 billion). Excluding the fi rst-time consolidation of International Power, net debt was down €2.1 billion and will decrease by a further €1.1 billion following receipt on July 12, 2011 of the proceeds from the sale of a stake in GRTgaz to the CDC-CNP consortium.

Changes in net debt over the period break down as follows in millions of euros:

4.1 CASH GENERATED FROM OPERATIONS BEFORE INCOME TAX AND WORKING CAPITAL REQUIREMENTS

Cash generated from operations before income tax and working capital requirements amounted to €8,670 million at June 30, 2011, up 8% on a reported basis compared with June 30, 2010. Growth in this item was in line with growth in EBITDA.

4.2 CHANGE IN WORKING CAPITAL REQUIREMENTS

The change in working capital requirements (WCR) represented a cash outfl ow of €741 million refl ecting the seasonality of the Group's operations. The rise in WCR was slightly higher than in the fi rst half of 2010 (€598 million), however, chiefl y due to greater gas inventories on account of warm weather during the period.

4.3 NET INVESTMENTS

Investments in fi rst-half 2011 totaled €4,199 million and included:

fi nancial investments for €387 million, concerning mainly the balancing contribution relating to the unwinding of cross-holdings with Acea in Italy and Sita Australia's acquisition of shares in WSN;
development expenditure totaling €2,397 million, principally incurred by the Energy Europe & International business line;
maintenance expenditure of €1,415 million.

Disposals in the fi rst half of 2011 represented €1,270 million and essentially related to the disposal of a portion of the Group's shareholdings and share capital reductions in inter-municipal companies (€695 million), the disposal of assets as part of the unwinding of cross-holdings with Acea in Italy (€182 million), and the disposal of equity interests in Noverco in Canada (€197 million).

Capital expenditure breaks down as follows by business line:

4.4 SHARE BUYBACKS AND DIVIDENDS

Total dividends paid in cash by GDF SUEZ SA to its shareholders amounted to €1,490 million. This amount corresponds to the balance of the €1.50 per share dividend paid on May 9, 2011, net of the interim €0.83 per share dividend paid on November 15, 2010 (i.e., €0.67 per share).

Dividends paid by various subsidiaries to non-controlling interests totaled €576 million and primarily comprised dividends in the amount of €226 million paid to non-controlling interests in International Power entities.

The Group also bought back its own shares for an amount of €85 million and increased its share capital by €16 million, chiefl y through an employee share issue.

4.5 NET DEBT AT JUNE 30, 2011

At June 30, 2011, net debt totaled €40,678 million. The gearing ratio came out at 51.6%, compared with a ratio of 48% at end-December 2010.

Including the impact of fi nancial instruments, 46% of net debt is denominated in euros and 24% in US dollars.

Including the impact of fi nancial instruments, 77% of net debt is at fi xed rates.

The average maturity of net debt rose to 10 years, refl ecting bond issues carried out during the period.

At June 30, 2011, the Group had undrawn credit facilities and commercial paper back-up lines totaling €14,910 million.

5 OTHER ITEMS IN THE STATEMENT OF FINANCIAL POSITION

Property, plant and equipment and intangible assets stood at €101.7 billion at June 30, 2011, versus €91.5 billion at December 31, 2010. This €10.2 billion increase stems chiefl y from changes in the scope of consolidation relating to the acquisition of the International Power group and the Acea transaction.

Goodwill climbed €2.4 billion to €30.3 billion at June 30, 2011. This rise was due mainly to the acquisition of the International Power group.

Available-for-sale securities advanced €0.6 billion to €3.8 billion and now include the Group's interest in Flemish inter-municipal companies further to the Group ceasing to exercise signifi cant infl uence over these companies.

Investments in associates totaled €2.6 billion, up €0.6 billion due mainly to the inclusion of International Power associates in the consolidated fi nancial statements, including PT Paiton Energy Company (Indonesia), Tejo Energia (Portugal) and ISAB Energy (Italy).

Total equity amounted to €78.8 billion, up €8.2 billion from December 31, 2010, essentially refl ecting net income for the period (€3.5 billion), dividend payments (€-2.3 billion), translation losses (€1.1 billion) and the impact of changes in the scope of consolidation during the period (€7.7 billion).

Provisions rose €0.4 billion to €14.9 billion. The increase chiefl y results from changes in the scope of consolidation (€0.3 billion) and the impact of unwinding discount adjustments (€0.2 billion), partly offset (€-0.1 billion) by actuarial gains and losses on provisions for pensions and other employee benefi ts.

6 RELATED PARTY TRANSACTIONS

Related party transactions are described in Note 24 to the consolidated fi nancial statements included in the 2010 Reference Document. An update is provided in Note 11 to the condensed interim consolidated fi nancial statements for the six months ended June 30, 2011.

7 DESCRIPTION OF THE MAIN RISKS AND UNCERTAINTIES FOR THE SECOND HALF OF 2011

The Risk Factors section of GDF SUEZ's 2010 Reference Document (Section 5) provides a detailed description of the risk factors to which the Group is exposed. Developments over the period in litigation and the risks arising from fi nancial instruments to which the Group is exposed are respectively set out in Note 10 and Note 8 to the condensed interim consolidated fi nancial statements for the six months ended June 30, 2011.

The Group has not identifi ed any risks or uncertainties other than those described in this document.

8 OUTLOOK

First-half results enable us to confi rm a 2011 Ebitda target between €17 and €17.5 billion(1), before unfavorable weather impact of the fi rst semester and the risk on the French gas retail tariff. At the end of June, the unfavorable weather impact on our domestic markets is estimated at €465 million. The risk of freeze for the gas public distribution tariff in France depends on decisions to come, providing that each 1% shortfall from October 1, 2011 between supply cost and tariff is estimated, based on August forwards, at €40 million.

During the second half, the Group will work actively on its regulatory environment, continue its integration and restructuration, in particular with the creation of a Energy Europe business line, implement its cooperation agreement with CIC, and pursue its portfolio optimization and investments program, with a view to increasing profi tability.

On November 15, 2011, the Group will distribute an interim dividend of €0.83 per share for 2011, identical to the interim dividend paid one year ago. The Board of Directors will recommend the total amount of the dividend to be paid for 2011 at the Shareholders' Meeting on April 23, 2012.

⁽¹⁾ Assuming average weather conditions and no major changes in the regulatory or economic environment. Underlying assumptions for 2011 are: average Brent \$92/bbl; average electricity baseload Belgium €50/MWh; average price of gas at Zeebrugge €23/MWh.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

INFORMATION ON THE GDF SUEZ GROUP

GDF SUEZ SA, the parent company of the GDF SUEZ Group, is a French société anonyme with a Board of Directors that is subject to the provisions of Book II of the French Commercial Code (Code de commerce), as well as all other provisions of French law applicable to commercial companies. GDF SUEZ was incorporated on November 20, 2004 for a period of 99 years.

It is governed by current and future laws and by regulations applicable to sociétés anonymes and its bylaws.

The Group is headquartered at 1 place Samuel de Champlain – 92400 Courbevoie (France).

GDF SUEZ shares are listed on the Paris, Brussels and Luxembourg stock exchanges. The Group is one of the world's leading energy providers, active across the entire energy value chain – upstream and downstream – in both electricity and natural gas. It develops its businesses (energy, energy services and environment) around a responsible growth model in order to meet the challenges of satisfying energy needs, safeguarding supplies, combating climate change and optimizing the use of resources.

On August 9, 2011, the Group's Board of Directors approved and authorized for issue the condensed interim consolidated fi nancial statements of GDF SUEZ and its subsidiaries for the six months ended June 30, 2011.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1.1 Basis of preparation

In accordance with the European Regulation on international accounting standards dated July 19, 2002, the Group's annual consolidated fi nancial statements are prepared in accordance with International Financial Reporting Standards (IFRS) as published by the International Accounting Standards Board (IASB) and endorsed by the European Union (1).

The Group's condensed interim consolidated fi nancial statements for the six months ended June 30, 2011 were prepared in accordance with the provisions of IAS 34 – Interim Financial Reporting, which allows entities to present selected explanatory notes. The condensed interim consolidated fi nancial statements for the six months ended June 30, 2011 do not therefore incorporate all of the notes and disclosures required by IFRS for the annual consolidated fi nancial statements, and accordingly must be read in conjunction with the consolidated fi nancial statements for the year ended December 31, 2010, subject to specifi c provisions relating to the preparation of interim fi nancial information as described hereafter.

1.2 Restatements made to the 2010 consolidated fi nancial statements in accordance with IAS 8

During the six months ended June 30, 2011, an error in the computation of "gas in the meter" receivable accounted for in the Energy – France segment was discovered . This error is due to the use of an incomplete model and certain incorrect calculation parameters. As most of the cumulated impact of this error originated before July 22, 2008 (date of the merger of Gaz de France and Suez) the fair value of assets acquired in this transaction has been restated resulting in the correction of goodwill, the cost of business combination being unchanged. Accordingly, the comparative amounts for the year ended December 31, 2010 related to Goodwill, Trade and other receivables, Deferred Tax Assets, Other liabilities and Equity have been respectively restated for +€366 million, -€833 million, +€240 million, -€137 million and -€91 million. The comparative income statement information related to the six months ended June 2010, the twelve months ended December 31, 2010 and the Energy –France segment key

⁽¹⁾ Available on the European Commission's website: http://ec.europa.eu/internal_market/accounting/index_en.htm.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

indicators have not been restated as this error did not have material impact. Thus, basic and diluted earnings per share have not been restated for the presented periods. 2009 and 2008 income was not materially impacted either.

Appropriate measures were implemented during the six months ended June 30, 2011, to strengthen the reliability of the "gas in the meter" computation model in the Energy – France segment and to reinforce internal control accordingly.

This error by no means modifi ed amounts billed to the 10.1 million customers in France.

1.3 Accounting policies

The accounting policies used to prepare the Group's condensed interim consolidated fi nancial statements for the six months ended June 30, 2011 are consistent with those used to prepare the consolidated fi nancial statements for the year ended December 31, 2010 in accordance with IFRS as published by the IASB and endorsed by the European Union, with the exception of the following items in Note 1.3.1:

1.3.1 IFRS standards, amendments and IFRIC interpretations applicable in 2011

Revised IAS 24 Related Party Disclosures; as authorized by the standard, the Group has elected to early adopt in its consolidated fi nancial statements for the year ended December 31, 2010 provisions regarding exemptions to disclosures by governmentrelated entities. Accordingly, the new defi nition of a related party per the revised standard will be applied in the consolidated fi nancial statements for the year ended December 31, 2011.
Amendment to IAS 32 Classifi cation of Rights Issues: this amendment has no impact on the condensed interim consolidated fi nancial statements ended June 30, 2011.
Improvements to IFRS 2010: among amendments, those related to IAS 34 and IFRS 7 impact fi nancial instruments disclosures as of June 30, 2011. Refer to Notes 7 and 8.
IFRIC 19 Extinguishing Financial Liabilities with Equity Instruments: this interpretation has no impact on the condensed interim consolidated fi nancial statements ended June 30, 2011.
Amendment to IFRIC 14 Prepayments of a Minimum Funding Requirement: this amendment has no signifi cant impact on the condensed interim consolidated fi nancial statements ended June 30, 2011.

1.3.2 IFRS standards effective after 2011 that the Group has elected not to early adopt in 2011

Standards and amendments applicable in 2012

Amendments to IAS 12 Deferred tax: recovery of underlying assets (2)
Amendments to IAS 1 Presentation of Items of Other Comprehensive Income(2)
Amendment to IFRS 7 Disclosures transfers of fi nancial assets(2)

Standards and amendments applicable in 2013

IFRS 9 Financial Instruments: Classifi cation and measurement(2)

IFRS 12 Disclosure of Interests in Other Entities(2)
Amendment to IAS 27 Separate Financial Statements(2)
Amendment to IAS 28 Investments in Associates and joint ventures(2)
IFRS 13 Fair value measurement(2)
Amendments to IAS 19 Employee benefi ts(2)

The impact resulting from the application of these new or revised standards is currently being assessed.

1.4 Use of estimates and judgment

Estimates

The preparation of consolidated fi nancial statements requires the use of estimates and assumptions to determine the value of assets and liabilities, and contingent assets and liabilities at the statement of fi nancial position reporting date, as well as revenues and expenses reported during the period.

Due to uncertainties inherent in the estimation process, the Group regularly revises its estimates in light of currently available information. Final outcomes could differ from those estimates.

The key estimates used in preparing the Group's consolidated fi nancial statements relate mainly to:

measurement of the fair value of assets acquired and liabilities assumed in a business combination;
measurement of the recoverable amount of goodwill, property, plant and equipment and intangible assets;

(2) Not yet endorsed by the European Union.

MAIN CHANGES IN GROUP STRUCTURE

measurement of provisions, particularly for nuclear waste processing and storage, dismantling obligations, disputes, pensions and other employee benefi ts;
fi nancial instruments;
measurement of revenues not yet metered, so called un-metered revenues;
measurement of recognized tax loss carry-forwards.

Detailed information related to the use of estimates is provided in Note 1 to the consolidated fi nancial statements for the year ended December 31, 2010.

Judgment

As well as relying on estimates, Group management also makes judgments to defi ne the appropriate accounting policies to apply to certain activities and transactions, particularly when the effective IFRS standards and interpretations do not specifi cally deal with related accounting issues.

In particular, the Group exercised its judgment in determining the accounting treatment applicable to concession contracts, the classifi cation of arrangements which contain a lease, the recognition of acquisitions of non-controlling interests prior to January 1, 2010 and the identifi cation of electricity and gas purchase and sale "own use" contracts as defi ned by IAS 39.

In accordance with IAS 1, the Group's current and non-current assets and liabilities are shown separately on the consolidated statement of fi nancial position. For most of the Group's activities, the breakdown into current and non-current items is based on when assets are expected to be realized, or liabilities extinguished. Assets expected to be realized or liabilities extinguished within 12 months of the statement of fi nancial position date are classifi ed as current, while all other items are classifi ed as non-current.

1.5 Interim fi nancial reporting

Seasonality of operations

Although the Group's operations are intrinsically subject to seasonal fl uctuations, key performance indicators and income from operating activities are more infl uenced by changes in climatic conditions than by seasonality. Consequently, the interim results for the six months ended June 30, 2011 are not necessarily indicative of those that may be expected for full-year 2011.

Income tax expense

Current and deferred income tax expense for interim periods is calculated at the level of each tax entity by applying the average estimated annual effective tax rate for the current year to income for the period.

Pension benefi t obligations

Pension costs for interim periods are calculated on the basis of the actuarial valuations performed at the end of the prior year. If necessary, these valuations are adjusted to take account of curtailments, settlements or other major non-recurring events during the period. Furthermore, amounts recognized in the statement of fi nancial position in respect of defi ned benefi t plans are adjusted, if necessary, in order to refl ect material changes impacting the yield on investment-grade corporate bonds in the geographic area concerned (the benchmark used to determine the discount rate) and the actual return on plan assets.

NOTE 2 MAIN CHANGES IN GROUP STRUCTURE

2.1 Acquisition of International Power plc

2.1.1 Description of the combination

The acquisition of International Power plc ("International Power") by GDF SUEZ, publicly announced on August 10, 2010, was completed on February 3, 2011.

The main stages of this business combination were as follows:

August 10, 2010: the Boards of GDF SUEZ and International Power entered into a Memorandum of Understanding detailing the main terms and conditions of the proposed combination of International Power and GDF SUEZ Energy International business areas (outside Europe), along with certain assets in the United Kingdom and Turkey (collectively, "GDF SUEZ Energy International");
October 13, 2010: GDF SUEZ, Electrabel and International Power signed the Merger Deed and the other main agreements governing the relationship between GDF SUEZ and the new International Power group following the combination;
December 16, 2010: the general shareholders' meeting of International Power approved the combination with GDF SUEZ Energy International;
February 3, 2011: GDF SUEZ completed the acquisition of International Power, having met all conditions precedent. These included approval from certain regulatory or competition authorities, reorganizational measures concerning the corporate structure and scope of the assets and business contributed, and admission to listing on the Offi cial List of the UK Listing Authority (UKLA) and to trading on the London Stock Exchange's main market of the new International Power shares.

MAIN CHANGES IN GROUP STRUCTURE

The acquisition of International Power took the form of the contribution by GDF SUEZ of GDF SUEZ Energy International to International Power, in exchange for 3,554,347,956 new ordinary International Power shares issued on February 3, 2011.

As part of the contribution and in accordance with the Merger Deed, GDF SUEZ reorganized the corporate structure and scope of the assets and business contributed. GDF SUEZ also made equity contributions of €5,277 million and GBP 1,413 million (€1,659 million) to GDF SUEZ Energy International entities. On February 25, 2011, the entire sum of the GBP 1,413 million (€1,659 million) capital increase was used to fi nance a special dividend of GBP 0.92 per share, which was paid to shareholders – excluding holders of new ordinary shares – listed on the company's share register on February 11, 2011, the record date.

As a result of this combination, GDF SUEZ holds 69.78% of the voting rights of the International Power group.

The combination of International Power and GDF SUEZ Energy International creates a global leader in independent power generation. This will accelerate GDF SUEZ's industrial development and strengthen its international presence in the United States and United Kingdom, as well as in high-growth markets such as the Middle East and Asia.

International Power is fully consolidated in the Group's consolidated fi nancial statements with effect from February 3, 2011.

As part of obtaining regulatory clearance from the European Commission, on May 18, 2011, International Power entered into an agreement with Itochu concerning the sale of its interest in the T-Power project in Belgium. The purpose of the T-Power project is to build and operate a 420 MW combined cycle gas turbine facility.

2.1.2 Fair value of consideration transferred

The fair value of the consideration transferred to acquire 69.78% of International Power was calculated based on the price of International Power shares on February 3, 2011, the date of the business combination. The fair value transferred amounted to €5,130 million, corresponding to the 1,073 million International Power shares acquired (i.e., 69.78% of existing International Power shares prior to the transaction) multiplied by the February 3 share price of GBP 4.08 per share (1 GBP = €1.17).

2.1.3 Impact of the acquisition on the consolidated fi nancial statements

The Group elected to measure non-controlling interests at their fair value. The fair value of the non-controlling interests corresponding to the 30.22% of International Power shares that are not held by the Group, was calculated based on the price of International Power shares on February 3, 2011. Investments held by third parties in subsidiaries acquired from International Power are measured either based on the discounted future cash flow method or the discounted dividend model. For the merchant entities the fair value of plants was determined based on market assumptions available at the acquisition date concerning the price of electricity and fuel, as well as long-term assumptions refl ecting the expected trends in the price of raw materials. For entities with contracted plants, the fair value was calculated based on existing business plans and forecasts at the acquisition date. The discount rates applied were based on the specifi c characteristics of the operating entities concerned.

Prior to the acquisition, GDF SUEZ and International Power held 30% and 40%, respectively, of Middle Eastern entity Hidd Power Company. Hidd Power Company was previously accounted for using the equity method in the consolidated fi nancial statements of GDF SUEZ and International Power. Following the acquisition of International Power, the Group obtained control of Hidd Power Company and in accordance with IFRS 3, remeasured its previouslyheld equity interests at fair value. The negative €5 million impact of this remeasurement and of recycling to income amounts relating to cash fl ow hedges recognized in "Other comprehensive income" is presented under "Changes in scope of consolidation" within income from operating activities.

At June 30, 2011, the accounting for the business combination was provisional. It will be fi nalized during the second half of 2011.

The following table shows the provisional fair values of the identifi able assets and liabilities of International Power at acquisition date:

In millions of euros	Total

Unwinding of the foreign currency derivatives hedging the special dividend	23
Non-controlling interests	3,007
GOODWILL	2,649

MAIN CHANGES IN GROUP STRUCTURE

Goodwill amounting to €2,649 million mainly refl ects expected operating synergies (optimization of central and regional costs and long-term maintenance agreements, reorganization of purchasing and trading activities, etc.), fi nancial synergies (refi nancing certain borrowings to benefi t from the lower fi nancing costs applicable to the new Group) as well as potential for growth and market share.

This acquisition resulted in a €6,330 million increase in equity, of which €6,171 million related to non-controlling interests. The remaining €159 million impact on shareholders' equity refl ects the 30% dilution of the Group's interest in GDF SUEZ Energy International as a result of the acquisition of a 69.78% controlling interest in International Power.

This transaction was completed in February 2011 and had a net negative impact of €421 million on the Group's cash fl ows, which breaks down as:

cash and cash equivalents acquired at the acquisition date: €1,238 million;
payment of a special dividend: €1,659 million.

Acquisition-related costs totaled €64 million, the majority of which were recognized in the second half of 2010.

The contribution of entities acquired from International Power to revenues, current operating income and net income Group share for the six months to June 30, 2011 amounted to €1,784 million, €223 million and €157 million, respectively.

If the acquisition had taken place on January 1, 2011, the contribution to revenues and net income Group share would have been €334 million and €72 million, respectively.

2.2 Entry of a 25% minority shareholder in GRTgaz

On June 27, 2011, the Group and the public consortium composed of CNP Assurances, CDC Infrastructure and Caisse des Dépôts entered into a long-term partnership in natural gas transmission.

Pursuant to the investment agreement, the consortium acquired 25% of the share capital and voting rights of the Group's subsidiary GRTgaz, a natural gas transmission network operator in France, for a consideration of €1,110 million. On July 12, 2011, the Group received this amount through (i) the payment of €810 million for the acquisition of 9,782,609 shares representing 18.2% of the share capital and (ii) the subscription of 3,263,188 shares representing 6.8% of the share capital as part of a €300 million reserved capital increase.

Prior to these transactions, GRTgaz paid GDF SUEZ a special dividend of €805 million. GDF SUEZ remains entitled to the GRTgaz dividend for 2010.

The sale of this minority stake was effective on June 27, 2011, the date on which the investment agreement and the GRTgaz shareholders' agreement were signed and the conditions precedent were met. The Group retains exclusive control of GRTgaz.

As the sale relates to a non-controlling interest, the difference between the selling price and the carrying amount of the interest sold, amounting to €185 million, was recognized in shareholders' equity. At June 30, 2011, the Group recorded the receivable relating to the consideration payable by the consortium within "Trade and other receivables" in the statement of fi nancial position.

2.3 Investment in electricity and gas distribution in Belgium

During the fi rst half of 2011, various transactions were carried out in Flanders and Wallonia concerning the capital of the mixed intermunicipal electricity and gas distribution network operators in which Electrabel, a wholly-owned subsidiary, holds interests.

These transactions are in line with the previous agreements between the Group and the public sector as part of the process of deregulating the energy markets, as well as the intention of the European Union and Belgian legislature to give greater independence to transmission and distribution network operators.

In Flanders, share capital reductions were carried out in June 2011, immediately followed by share capital increases subscribed in full by the public sector. These changes reduced the Group's voting rights at general shareholders' meetings.

Further to these transactions, and given the specifi c context in Flanders, in particular the regional law that requires Electrabel to sell all of its interests in Flemish distribution network operators by 2018, the Group decided to irrevocably waive all representation in the management bodies of Eandis, the sole network operator, and to substantially reduce its voting rights in the decision-making bodies of the mixed inter-municipal companies. The provisions taken regarding governance impacted both Electrabel's representation on the boards of directors as well as its voting rights at general shareholders' meetings.

In view of these transactions, as of June 30, 2011 the Group no longer exercises signifi cant infl uence over the Flemish intermunicipal companies. Accordingly, the equity method is no longer applicable and the corresponding shares are presented under "Available-for-sale securities" in the interim consolidated fi nancial statements for the six months ended June 30, 2011. In accordance with the applicable standards, the residual interest was recognized at fair value. The difference between carrying amount and fair value, in the amount of €425 million, was recognized in the income statement under "Changes in scope of consolidation" within income from operating activities.

In Wallonia, the Group sold 5% of its shares in inter-municipal companies, bringing its interest to 25% at June 30, 2011. This sale resulted in a €83 million capital gain, recognized in "Changes in scope of consolidation".

Share capital reductions were also carried out at the inter-municipal companies in Wallonia during June 2011. As the Group's share of these capital reductions exceeded the carrying amount of the equity investment, the surplus was taken to income and the value of the shares was reduced in full. The positive €49 million impact was recognized in "Share in net income of associates". The recognition of the Group's share in net income from these entities for subsequent periods is suspended until the surplus is cancelled out.

The legal and political context specifi c to inter-municipal companies in the Walloon region did not result in any changes in the governance of these entities, which continue to be accounted for using the equity method in the Group's consolidated fi nancial statements.

2.4 Completion of the agreement with Acea Spa concerning the termination of the partnership between the two groups for energy activities in Italy

The agreement dated December 16, 2010 terminated the partnership and shareholder agreement between the Group and Acea concerning energy activities in Italy. It came into effect during the fi rst quarter of 2011, after having met all conditions precedent.

In 2010, the Acea Electrabel group's activities were jointly controlled by GDF SUEZ and Acea and were therefore consolidated by the proportionate method in the Group's consolidated fi nancial statements.

Pursuant to the overall agreement entered into with Acea concerning the unwinding of cross-holdings, the parties conducted the following transactions:

• the Group acquired Acea's 50% interest in the capital of power production company Tirreno Power for €108 million, thereby raising the Group's interest in Tirreno Power from 35% to 50%. Tirreno Power is jointly held by Energia Italiana and continues to be consolidated using the proportionate method;

the Group acquired control of the trading activities of AceaElectrabel Trading Spa (AET) by acquiring AceaElectrabel's interest in AET for an amount of €20 million. AET is now wholly owned by the Group;
the Group transferred its 40.59% interest in AceaElectrabel Elettricita (AEE), a company that markets gas and power in the municipality of Rome, to Acea through the sale of its interest in AceaElectrabel for €57 million;
following a spinoff operation by AceaElectrabel Produzione Spa (AEP), some of AEP's power production assets (hydroelectric production assets and two other power plants near Rome) were transferred to an entity wholly owned by Acea. In consideration of this transfer of assets amounting to €130 million, the Group acquired control of AEP, of which it now owns the entire share capital (following the spinoff) for a price of €76 million;
the Group acquired pre-emptive rights over the hydroelectric assets transferred to Acea as well as over AEE for an amount of €9 million. Lastly, both groups bought back shareholder loans related to the unwinding transactions, which resulted in a net payment of €25 million to Acea.

This transaction allowed GDF SUEZ to complete the integration of its energy activities in Italy where it now manages the entire energy value chain, from the supply of gas to the sale and distribution of energy.

Following the acquisition of AEP and AET, the Group remeasured its previously-held interests in these entities in accordance with the revised IFRS 3. The net impact of this remeasurement and disposal amounted to a negative €6 million. These impacts are presented under "Changes in scope of consolidation" within income from operating activities.

At June 30, 2011, the accounting for the business combination was provisional. It will be fi nalized during the second half of 2011.

MAIN CHANGES IN GROUP STRUCTURE

The following table shows the carrying amount of identifi able assets and liabilities of AET, AEP and its subsidiaries, and Tirreno Power at June 30, 2011:

cash and cash equivalents acquired/sold at the acquisition date: €(174) million;
net disbursements on acquisitions, sale of shares and loan repayments: €(52) million.

Following the completion of all of the above transactions, the Group recognized a total of €72 million in goodwill.

For the six months ended June 30, 2011, the positive impact of these changes in scope of consolidation on revenues and net income Group share amount to €57 million and €9 million, respectively.

2.5 Other transactions during the fi rst half of 2011

Several other acquisitions and equity transactions took place in the fi rst half of 2011, including the acquisition of controlling interests in WSN Environmental Solutions in Australia and Proenergy Contracting in Germany. The individual and aggregate impacts of these transactions on the consolidated fi nancial statements for the six months ended June 30, 2011 are not material.

INCOME FROM OPERATING ACTIVITIES	5,664	6,114

4.1.1 Mark-to-market on commodity contracts other than trading instruments

In the fi rst half of 2011, this item represents a net loss of €95 million (compared with a net loss of €48 million in the fi rst half of 2010), chiefl y refl ecting:

• changes in the fair value of forward contracts used as economic hedges not eligible for hedge accounting, resulting in a net loss of €114 million compared with a net loss of €66 million in fi rst-half 2010. The loss results mainly from a negative price impact on hedges of power and gas sales due to increases in the underlying indices since December 31, 2010;

• the ineffective portion of cash fl ow hedges in respect of nonfi nancial assets, resulting in a gain of €27 million (versus a gain of €18 million in fi rst-half 2010).

4.1.2 Impairment of property, plant and equipment, intangible assets and fi nancial assets

In millions of euros	June 30, 2011	June 30, 2010

In addition to the annual impairment tests on goodwill and nonamortizable intangible assets carried out in the second half of the year, the Group also tests goodwill, property, plant and equipment and other intangible assets for impairment whenever there is an indication that the asset may be impaired.

4.1.2.1 Impairment of property, plant and equipment and intangible assets (excluding goodwill)

In the fi rst half of 2011, the Group recognized impairment losses on property, plant and equipment and intangible assets (excluding goodwill) in the amount of €45 million, with no individual impairment loss being material. Impairment losses recorded at June 30, 2010 mainly concerned certain assets in Spain within the Energy Europe business area in the amount of €156 million, of which €131 million related to a power generation unit due to its worsening economic context. In addition, the Group recognized impairment losses totaling €48 million against its exploration licenses in Egypt and the Gulf of Mexico, in light of development prospects.

4.1.2.2 Impairment of fi nancial assets

In the fi rst half of 2011, the Group recognized impairment losses on fi nancial assets in the amount of €32 million, with no individual impairment loss being material. At June 30, 2010, the Group recognized impairment losses against its Gas Natural shares in the amount of €46 million based on stock market price at that date.

A breakdown of available-for-sale securities and their values is presented in Note 7, "Financial instruments".

4.1.3 Restructuring costs

Restructuring costs for the fi rst half of 2011 mainly include costs relating to the implementation of the International Power combination and operating synergies (€19 million) and costs incurred to adapt to the economic environment in the Energy Services business line (€15 million).

At June 30, 2010, restructuring costs included costs incurred to adapt to the economic environment in the SUEZ Environnement (€50 million) and Energy Services (€34 million) business lines. This item also included ongoing costs for the streamlining of corporate premises in Brussels (€22 million) and Paris (€8 million).

4.1.4 Changes in scope of consolidation

At June 30, 2011, this item primarily refl ects the €425 million gain attributable to the remeasurement at fair value of the Group's interest in the Flemish inter-municipal companies further to the Group ceasing to exercise signifi cant infl uence over these entities, as described in Note 2, "Main changes in Group structure", and the recognition of the corresponding shares within "Available-for-sale securities". It also includes the capital gains on the disposal of a portion of the share capital of the inter-municipal companies in the Walloon region (€83 million) and the disposal of equity interests in Noverco (€28 million).

At June 30, 2010, this item comprised the capital gains on the disposal of Fluxys (€422 million) and Elia shares (€238 million), and of interests in Société des Eaux de Marseille and Société des Eaux d'Arles in connection with the unwinding of cross-holdings with the Veolia Environnement-Compagnie Générale des Eaux group (€81 million). It also included the impacts of remeasuring the interests previously held (i) in power and transportation assets in Chile (€147 million), (ii) in Lyonnaise des Eaux following the acquisition of controlling interests as part of the unwinding of the cross-holdings with the Veolia Environnement-Compagnie Générale des Eaux group (€120 million), and (iii) in connection with the acquisition of a controlling interest in the Hisusa/Agbar group (€167 million).

4.1.5 Other non-recurring items

At June 30, 2011, this item mainly includes €39 million in capital gains on the disposal of property, plant and equipment in the SUEZ Environment business line.

At June 30, 2010, this item essentially comprised the capital gains on the disposal of shares in VNG by Global Gas & LNG.

NET FINANCIAL INCOME/(LOSS)	(1,613)	538	(1,075)	(1,411)	341	(1,070)

The decrease in the cost of net debt is essentially attributable to positive changes in the fair value of economic currency and interest rate hedges. This impact combined with an increase in gains on cash investments, more than offset the increase in gross interest expense resulting from the increase in average gross debt compared to the fi rst half of 2010 (see Note 7.3, "Net debt").

4.3 Income tax expense

In millions of euros	June 30, 2011	June 30, 2010
Net income (A)	3,519	4,145
Total income tax expense recognized in income for the period (B)	(1,371)	(1,086)
Share in net income of associates (C)	300	188
INCOME BEFORE INCOME TAX EXPENSE AND SHARE IN NET INCOME OF ASSOCIATES (A)-(B)-(C)=(D)	4,590	5,044
EFFECTIVE TAX RATE - (B)/(D)	29.9%	21.5%

The increase in the effective tax rate resulted primarily from:

the increase in the proportion of income generated by Exploration & Production entities whose tax rate exceeds 50%;
the increase in the tax rate from 50% to 62% at end-March 2011 on Exploration & Production activities in the United Kingdom;
the recognition of income tax expense in the fi rst half of 2011 relating to nuclear activities in Belgium;
the signifi cant amount of gains on disposal and on changes in scope of consolidation recognized during the fi rst half of 2010 (which for the most part have no tax impact).

In light of recent parliamentary debates in Belgium relating to the tax rate on nuclear activities, the various positions of the political parties and the failure to implement legislation in relation to agreements to extend the operating life of certain nuclear reactors, the Group estimates that it will have to pay a tax in respect of full-year 2011 in the same amount as in 2010, i.e., €212 million. Income tax expense at June 30, 2011 therefore includes this levy on nuclear activities in Belgium, which was not recognized in the fi rst half of 2010.

Changes in scope of consolidation and other in the fi rst half of the year primarily result from the acquisition of the International Power group and the Acea transaction as described in Note 2, "Main changes in Group structure".

Translation adjustments recorded on the net amount of property, plant and equipment chiefl y relate to translation losses on the US dollar (€988 million), the pound sterling (€218 million), the Chilean peso (€174 million), the Thai baht (€145 million) and the Brazilian real (€66 million), and translation gains on the Australian dollar (€67 million).

The increase in the carrying amount of investments in associates is mainly attributable to the inclusion of International Power associates in the consolidated fi nancial statements. The International Power transaction is described in further detail in Note 2, "Main changes in Group structure".

As indicated in Note 2, "Main changes in Group structure", share capital reductions were carried out at the Flemish and Walloon inter-municipal companies in June 2011. As the Group's share of these capital reductions exceeded the carrying amount of the equity investments in associates, the surplus was taken to income and the value of the shares was reduced in full. As a result a positive impact of €49 million was recognized in "Share in net income of associates". The recognition of the Group's share in the profi t of these associates in future periods will be suspended until the surplus is cancelled out.

Finally, the Group disposed of its interest in Noverco on June 30, 2011.

At June 30, 2011, total unrecognized losses of associates (corresponding to the cumulative amount of losses including other comprehensive income or expense exceeding the carrying amount of the investments in the associates concerned), amounted to €170 million. These unrecognized losses mainly correspond to the negative fair value of financial instruments designated as interest rate hedges ("Other comprehensive income") used in financing constructions of power and desalination plants by associates in the Middle East.

(a) This item corresponds to the revaluation of the interest rate component of debt in a designated fair value hedging relationship. (b) This represents the fair value of debt-related derivatives, irrespective of whether or not they are designated as hedges.

7.3.2 Main events of the period

During the fi rst half of 2011, changes in the scope of consolidation led to a €7,571 million increase in net debt, of which €6,601 million is attributable to the fi rst-time consolidation of the International Power group, €694 million to the full consolidation of Hidd Power Company (previously equity accounted) following the acquisition of International Power, and €174 million to the Acea transaction.

The International Power debt acquired includes three convertible bonds into International Powers shares, as follows:

a USD 229 million (€158 million) bond issue maturing in 2023 and paying interest of 3.75%;
a €230 million bond issue maturing in 2013 and paying interest of 3.25%;
a €700 million bond issue maturing in 2015 and paying interest of 4.75%.

As the bonds were denominated in a currency other than the functional currency of International Power, the conversion options are recognized as derivatives at fair value through income. The fair value at acquisition date of these instruments' debt component amounted to €1,129 million. The fair value of the derivative instruments is recognized in "Derivatives hedging other items" in an amount of €370 million, and is therefore not included in net debt. Changes in the fair value of these derivative instruments in the fi rst half of the year amounted to €25 million, presented in "Other fi nancial income".

Changes in exchange rates resulted in a €801 million decrease in net debt (including €711 million in relation to the US dollar).

The Group performed the following transactions relating to its bond debt during the fi rst half of 2011:

GDF SUEZ SA issued a €300 million 100-year bond maturing in March 2111 and paying interest of 5.95%;
on May 5, 2011, Suez Environnement Company launched a combined intermediated redemption and exchange of its bonds maturing in 2014, issued in 2009 and paying interest of 4.875%. The purpose of this transaction was (i) to refi nance a portion of the bonds maturing in 2014 and (ii) to extend the average maturity of Suez Environnement Company's debt. At the close of the transaction, €338 million in bonds maturing in 2014 had been redeemed and exchanged as part of a €500 million 10-year bond issue paying interest of 4.078%;
the Group redeemed the Belgelec and Tractebel Energia bond issues (€400 million and €339 million, respectively) which expired during the fi rst half of the year.

Lastly, the Group paid off in advance of term the external debt of International Power's North American entities, which amounted to USD 1,125 million at the transaction date. These repayments were made out of available cash and therefore had no impact on net debt.

The sharp rises in forward prices for power and commodities (coal, oil, natural gas in Europe) observed in the fi rst half of 2011 resulted in major changes in the fair value of derivative hedging instruments (economic hedges or designated cash fl ow hedges in accordance with IAS 39) and of derivatives relating to trading activities.

7.4.4 Classifi cation of fi nancial instruments and fair value by level

In fi rst-half 2011, the Group made no signifi cant changes in the classifi cation of fi nancial instruments and did not recognize any material transfers between levels of the fair value hierarchy.

GDF SUEZ mainly uses derivative instruments to manage its exposure to market risks. The Group's risk management policy is described in Note 15 to the consolidated fi nancial statements for the year ended December 31, 2010.

In view of its power generation and international sales activities as well as its fi nancial structure, the activities acquired from International Power are exposed to the following fi nancial risks:

market risk on commodity prices, which includes risks related to changes in prices and volumes, both for portfolio management and trading activities;
currency risk (translation risk and transaction risk), mainly in respect of the US dollar, the pound sterling and the Australian dollar;
interest rate risk related to the fi nancing of power plants;

EUR/USD	+10%	171	(164)
EUR/GBP	+10%	(30)	3

As options contracts are not frequently used, the sensitivity analysis is symmetrical for price increases and decreases.

8.1.1.2 Trading activities

On May 2, 2011, the Group combined the trading activities of Gaselys and Electrabel in Europe into a single dedicated unit, GDF SUEZ Trading. The purpose of this wholly-owned company is to (i) assist Group entities in optimizing their asset portfolios; (ii) create and implement energy price risk management solutions; and (iii) develop its own activities.

The use of Value-at-Risk (VaR) to quantify market risk arising from trading activities provides a transversal measure of risk taking all markets and products into account. VaR represents the maximum potential loss on a portfolio of assets over a specifi ed holding period based on a given confi dence interval.

The Group uses a 1-day holding period and a 99% confi dence interval to calculate VaR.

• counterparty risk;

• liquidity risk.

At June 30, 2011, the International Power group's activities and positions exposed to these different risks were integrated into the GDF SUEZ Group's risk management, monitoring and control procedures which are presented in Chapter 5 "Risk factors" of the 2010 Reference Document. The procedures with respect to exposure to market risk on commodity prices were supplemented by July 1, 2011 with the implementation of a new risk mandate.

Consequently, the exposures and sensitivity analyses presented in the tables below include data relating to International Power.

Value-at-Risk In millions of euros	June 30, 2011	2011 average(a)	2011 maximum(b)	2011 minimum(b)
Trading activities	4	5	10	2

(a) Average daily VaR. (b) Based on month-end highs and lows observed in 2011.

8.1.2 Currency risk

Sensitivity was analyzed based on the Group's net debt position including the impact of interest rate and currency derivatives at the closing date.

For currency risk, sensitivity corresponds to a 10% rise or fall in exchange rates compared to closing rates.

Impact on income

Changes in exchange rates against the euro only affect income via gains and losses on liabilities denominated in a currency other than the functional currency of companies carrying the liabilities on their statements of fi nancial position, and when the liabilities in question do not qualify as net investment hedges. The impact of a uniform increase (or decrease) of 10% in foreign currencies against the euro would ultimately be a gain (or loss) of €152 million.

Impact on equity

For fi nancial liabilities (debt and derivatives) designated as net investment hedges, a uniform adverse change of 10% in foreign currencies against the euro would have a positive impact of €314 million on equity. This impact is countered by the offsetting change in the net investment hedged.

8.1.3 Interest rate risk

Sensitivity was analyzed based on the Group's net debt position (including the impact of interest rate and currency derivatives) at the closing date.

For interest rate risk, sensitivity corresponds to a 1% rise or fall in the yield curve compared with period-end interest rates.

Impact on income

A uniform rise of 1% in short-term interest rates (across all currencies) on the nominal amount of fl oating-rate net debt and the fl oating-rate leg of derivatives, would increase net interest expense by €106 million. A fall of 1% in short-term interest rates would reduce net interest expense by €138 million. The asymmetrical impacts are attributable to the interest rate options portfolio, as well as to the low short-term interest rates (less than 1%) applicable to certain fi nancial assets and liabilities.

In the income statement, a rise of 1% in interest rates (across all currencies) would result in a gain of €194 million attributable to changes in the fair value of derivatives not documented or designated as net investment hedges. However, a fall of 1% in interest rates would generate a loss of €118 million. The asymmetrical impacts are attributable to the interest rate options portfolio.

Impact on equity

A uniform rise or fall of 1% in interest rates (across all currencies) would have a positive or negative impact of €427 million on equity, attributable to changes in the fair value of derivative instruments designated as cash fl ow hedges recognized in the statement of fi nancial position.

8.2 Counterparty risk

The Group is exposed to counterparty risk from customers, suppliers, intermediaries and banks on its operating and fi nancing activities, when such parties are unable to honor their contractual obligations.

8.2.1 Operating activities

Past-due trade and other receivables are analyzed below:

Trade and other			Assets neither Impaired impaired nor Past due assets not impaired at the reporting date assets past due
receivables In millions of euros	0-6 months	6-12 months	More than 1 year	Total	Total	Total	Total
At June 30, 2011	1,438	332	341	2,111	1,585	22,834	26,529

In view of the diversity of its customer portfolio, the Group does not consider that it is exposed to any material concentration of risk in respect of receivables.

In the case of commodity derivatives, counterparty risk arises from positive fair value. Counterparty risk is taken into account when calculating the fair value of these derivative instruments.

	June 30, 2011
Counterparty risk(a) In millions of euros	Investment grade(b)	Total(d)
Gross exposure	8,318	8,844
Net exposure(c)	2,804	3,068
% exposure to investment grade counterparties	91.4%

(a) Excluding positions with a negative fair value.

(b) Investment grade corresponds to transactions with counterparties rated at least BBB- by Standard & Poor's, Baa3 by Moody's, or an equivalent by Dun & Bradstreet. Counterparties are also qualifi ed as investment grade based on publicly available credit ratings, taking into account collateral, letters of credit and parent company guarantees.

(d) The difference between the amount exposed to counterparty risk and the total amount of derivatives hedging commodities under assets results from trade receivables and commodity purchase and sale contracts entered into within the ordinary course of business.

8.2.2 Financing activities

8.2.2.1 Counterparty risk arising from loans and receivables at amortized cost (excluding trade and other receivables)

The balance of outstanding past-due loans and receivables at amortized cost (excluding trade and other receivables) is analyzed below:

Loans and receivables at amortized cost (excluding trade and other receivables) In millions of euros			Past due assets not impaired at the reporting date		Impaired assets	Assets neither impaired nor past due
	0-6 months	6-12 months	More than 1 year	Total	Total	Total	Total
At June 30, 2011	10	8	16	35	413	5,297	5,745

The balance of outstanding loans and receivables carried at amortized cost (excluding trade and other receivables) does not include impairment losses or changes in fair value and in amortized cost, which totaled €(384) million, €(2) million, and €177 million, respectively, at June 30, 2011.

8.2.2.2 Counterparty risk arising from investing activities and the use of derivative fi nancial instruments

The Group is exposed to counterparty risk arising from investments of surplus cash and from the use of derivative fi nancial instruments. In the case of fi nancial instruments at fair value through income, counterparty risk arises on instruments with a positive fair value.

At June 30, 2011, total outstandings exposed to credit risk amounted to €12,995 million.

		June 30, 2011
Counterparty risk arising from investing activities In millions of euros	Total	Investment grade(a)	Unrated(b)	Non-investment grade(b)
Gross exposure	12,995	84%	13%	3%
Net exposure(c)	12,607	83%	14%	3%

(a) Counterparties rated at least BBB- by Standard & Poor's or Baa3 by Moody's.

(b) The bulk of exposure to unrated or non-investment grade counterparties arises within consolidated companies comprising non-controlling interests, or within Group companies operating in emerging countries where cash cannot be pooled and is therefore invested locally.

At June 30, 2011, no single counterparty represented more than 9% of cash investments.

8.3 Liquidity risk

In the context of its operating activities, the Group is exposed to a risk of having insuffi cient liquidity to meet its contractual obligations. Margin calls required in certain commodities market activities are included in the calculation of working capital requirements.

The Group's liquidity is based on maintaining cash and cash equivalents and access to confi rmed credit facilities. These facilities are appropriate for the scale of its operations and for the timing of contractual debt repayments. Confi rmed credit facilities had been granted for a total of €16,462 million at June 30, 2011, of which €1,552 million had been drawn down. 72% of total credit lines and 80% of undrawn facilities are centralized.

At June 30, 2011, bank loans accounted for 41% of outstanding borrowings and debt (excluding bank overdrafts and current accounts), while the remaining debt was raised on capital markets (including €26,340 million in bonds, or 53% of gross debt). Shortterm commercial paper issues represented 6% of gross debt and totaled €3,347 million at June 30, 2011.

Available cash, comprising cash and cash equivalents, fi nancial assets qualifying or designated as at fair value through income, less overdrafts, totaled €10,357 million at June 30, 2011.

8.3.1 Undiscounted contractual payments related to fi nancing activities

At June 30, 2011, undiscounted contractual payments on net debt (excluding the impact of derivatives and amortized cost) break down as follows by maturity:

9.1 GDF SUEZ bonus and performance shares

9.1.1 Performance share plan of January 13, 2011

On January 13, 2011, the Board of Directors approved the allocation of 3,426,186 performance shares to members of the Group's executive and senior management in two tranches:

performance shares vesting on March 14, 2014, subject to a further two-year non-transferability period; and
performance shares vesting on March 14, 2015.

Each tranche is made up of various instruments subject to different conditions:

instruments with a single condition: performance shares subject to an internal performance condition relating to the level of Group EDITDA in 2013;
instruments with two conditions: performance shares subject to an internal performance condition relating to Group EBITDA in 2013, and a market performance condition relating to the change in GDF SUEZ's share price compared to that of the Euro Stoxx Utilities index;
instruments with three conditions: performance shares subject to internal performance conditions relating to Group EBITDA and ROCE in 2013, and a market performance condition relating to the change in GDF SUEZ's share price compared to that of the Euro Stoxx Utilities index.

SHARE-BASED PAYMENT

9.1.2 Fair value of GDF SUEZ performance shares

The fair value of GDF SUEZ performance shares was calculated using the method described in Note 1 to the consolidated fi nancial statements for the year ended December 31, 2010 (section 1.4.14.2). The following assumptions were used to calculate the fair value of the new GDF SUEZ performance share plan awarded in 2011:

	January 2011 plan (GDF SUEZ)
	without performance condition	with external performance condition
Share price at grant date (€/share)	28.2	28.2
Expected dividend rate	5.5%	5.5%
Employee fi nancing costs	5.8%	5.8%
Non-transferability restriction (€/share)	1.0	1.0
Stock market-related performance condition	no	yes
Volatility of GDF SUEZ share		33.1%
Risk-free rate		2.1%
Volatility of the Euro Stoxx Utilities index		23.0%
Correlation between the share price and the index		84.4%
Fair value per share (€/share)*	22.6	12.3

* Weighted average.

An expense of €8 million was recognized with respect to this new plan for the six months ended June 30, 2011.

9.1.3 Bonus share plan of June 22, 2011

In line with the bonus share plans created by the Group since 2007, on June 22, 2011 the Board of Directors decided to implement a worldwide share ownership plan for Group employees with respect to 2011. On that date, the Group awarded all employees bonus shares amounting in total to nearly 4.3 million shares. The vesting period for these shares extends from June 22, 2011 to June 22, 2013. Shares are allocated defi nitively subject to the employee's presence in the Group on April 30, 2013. This plan did not have a material impact on the consolidated fi nancial statements for the six months ended June 30, 2011.

9.2 International Power stock option and performance share plans

International Power modifi ed its performance share plan prior to the date of acquisition by the Group. The 2008, 2009 and 2010 plans were cancelled in advance of their end dates. As compensation, benefi ciaries received a cash payment totaling €24 million paid after the acquisition date, while a liability in the same amount was recognized in International Power's statement of fi nancial position on the acquisition date. No expense was recorded in relation to performance share plans in the Group's income statement for the six months ended June 30, 2011.

In March 2011, International Power awarded 1,647,940 new performance shares to International Power executive and senior management. The amount recognized in the consolidated fi nancial statements for the six months ended June 30, 2011 with respect to this new plan and other International Power share-based payment plans was not material.

LEGAL AND ANTI-TRUST PROCEEDINGS

NOTE 10 LEGAL AND ANTI-TRUST PROCEEDINGS

The legal and arbitration proceedings presented hereafter are recognized as liabilities or are presented for information purposes.

In the normal course of business, the Group is party to a number of legal proceedings with third parties and is subject to antitrust inquiries. These points were described in Note 26 to the consolidated fi nancial statements for the year ended December 31, 2010. Consequently, this note only contains information on key developments in these proceedings, as well as new proceedings which have arisen since January 1, 2011. Provisions recorded in this respect totaled €612 million at June 30, 2011.

10.1 Legal proceedings

10.1.1 Slovak Gas Holding

The dispute between Slovak Gas Holding and the Slovak Republic relates to the legal and regulatory framework recently amended or redefi ned by the Slovak Republic in view of controlling SPP's ability to request price increases to cover gas selling costs. This method of controlling increases in gas prices contained in Slovak law under Lex SPP, was abolished in fi rst-half 2011.

Discussions between the parties are ongoing in a bid to settle the dispute outside of court.

10.1.2 Squeeze-out bid for Electrabel shares

At the hearing before the Court of Cassation on December 13, 2010, the Advocate General contended that the appeal brought by Deminor and others should be dismissed. On June 27, 2011, the Court of Cassation overturned the ruling of the Court of Appeal relating to the plaintiffs' case against GDF SUEZ. The Court of Cassation referred the plaintiffs' case against GDF SUEZ to the Brussels Court of Appeal, with a different composition. As the Court of Appeal is not bound by the grounds of the Court of Cassation's judgment, GDF SUEZ found itself in the same situation as at the hearings in March and April 2008.

Mr. Geenen appealed this decision before the Court of Cassation on June 2, 2010. These proceedings are still ongoing. A date has not yet been set for this case before the Court of Cassation. In view of the position taken by the Court of Cassation in the Deminor case, it is possible that the decision of the Court of Appeal will also be overturned in the near future and that this case will also be referred to the Brussels Court of Appeal, with a different composition.

10.1.3 UnitedWater – Lake DeForest

The claim for punitive damages introduced by the residents against United Water (SUEZ Environnement group) was fi nally dismissed on May 31, 2011. A ruling on the merits of the case is not expected before the end of fi rst-half 2012.

10.1.4 Novergie

On May 23, 2011, the criminal court handed down a fi ne of €250,000 to Novergie Centre Est.

Novergie Centre Est has appealed this decision.

10.1.5 Claims by the Belgian tax authorities

In 2010, the Group challenged the decision of the Belgian tax authorities' Special Tax Inspectorate before the Brussels Court of First Instance. This decision concerns the taxation by the Belgian tax authorities of fi nancial income generated in Luxembourg by the Luxembourg-based cash management branches of Electrabel and SUEZ-Tractebel SA.

An initial ruling on a peripheral question and not on the main issue, was handed down on May 25, 2011 in favor of Electrabel. The tax authorities have not indicated if they will appeal this ruling.

10.1.6 Compagnie du Vent

On November 27, 2007, Castelnou Energia (a subsidiary of Electrabel) acquired a 56.84% stake in Compagnie du Vent, with the original owner SOPER retaining a 43.16% stake. The founder of the company (and owner of SOPER), Jean-Michel Germa remained at the head of Compagnie du Vent. In 2009, GDF SUEZ SA replaced Castelnou Energia as the majority owner and Compagnie du Vent was integrated into the Energy France business line.

On May 27, 2011, at the Shareholders' Meeting of Compagnie du Vent, the Chairman and Chief Executive Offi cer, Jean-Michel Germa was removed and replaced by a senior executive chosen by GDF SUEZ. Jean-Michel Germa has contested this decision calling into question the validity of the Shareholders' Meeting, but by order of the President of the Commercial Court (Tribunal de Commerce) of Montpellier on June 8, 2011, Jean-Michel Germa is prohibited under penalty from using the title of Chairman and Chief Executive Offi cer of Compagnie du Vent and from entering the company's premises. Furthermore, on June 15, 2011, the President of the Commercial Court of Montpellier rejected SOPER's request, confi rming the order dated May 26, 2011 which allowed the Shareholders' Meeting to be held on May 27, 2011. SOPER and Jean-Michel Germa appealed both of these decisions.

Upon the request of GDF SUEZ, on July 13, 2011, the President of the Commercial Court of Montpellier acknowledged the abuse of minority rights by SOPER at the Shareholders' Meeting on July 1, 2010 by refusing to vote on the cooperation agreement for the Deux Côtes project between Compagnie du Vent and GDF SUEZ. He appointed a representative to represent SOPER at a subsequent Shareholders' Meeting on the same subject to vote in the company's name in accordance with the interests of Compagnie du Vent, without impinging on SOPER's interests. This Shareholders' Meeting was held on July 22, 2011 and the resolution was adopted. SOPER has however appealed the order of July 13, 2011. The Court of Appeal examined the case on July 27, 2011 and is due to hand down its judgment on September 8, 2011.

RELATED PARTY TRANSACTIONS

On July 29, 2011, SOPER summoned GDF SUEZ to appear at short notice before the Commercial Court of Paris on September 12, 2011 on the grounds that GDF SUEZ had not respected the agreements entered into between the two parties in November 2007.

The removal of the Chairman and Chief Executive Offi cer has shown that there are signifi cant strategic differences between the two shareholders in terms of wind power development, particularly in relation to the Deux Côtes project. These differences have led Jean-Michel Germa to threaten GDF SUEZ with a claim for compensation of approximately €489 million, which the Group considers to be unfounded.

10.2 Competition and concentration

10.2.1 Inquiry into the water distribution and treatment sector in France

The European Commission set the fi ne for the breach of a seal at €8 million and notifi ed Suez Environnement Company and Lyonnaise des Eaux France on May 24, 2011. This decision was not appealed.

10.2.2 Megal

The European Court has set the date of the hearing for September 21, 2011.

10.2.3 Inquiry on the term of power supply contracts in Belgium

In view of the results of its inquiry, on January 28, 2011 the European Commission decided to close the proceedings.

NOTE 11 RELATED PARTY TRANSACTIONS

Transactions with related parties during the period did not have a material impact on the Group's fi nancial position or results for the six months ended June 30, 2011.

Following the transactions and events that occurred in the fi rst half of the year (see Note 2, "Main changes in Group structure"), Flemish mixed inter-municipal companies and entities in the Acea-Electrabel group, with the exception of Tirreno Power, no longer represent related parties at June 30, 2011.

NOTE 12 SUBSEQUENT EVENTS

None.

We hereby declare that to the best of our knowledge, the condensed interim consolidated fi nancial statements for the six months ended June 31, 2011 have been prepared in accordance with the applicable accounting standards and give a true and fair view of the assets, liabilities, fi nancial position and results of operations of the Company and its subsidiaries, and that the interim management report provides a fair review of the signifi cant events of fi rst-half 2011, their impact on the interim fi nancial statements, the main related party transactions and the main risks and uncertainties to which the Group is exposed for the second half of 2011.

STATUTORY AUDITORS' REVIEW REPORT ON THE 2011 HALF-YEAR FINANCIAL INFORMATION

Period from January 1 to June 30, 2011

Statutory Auditors' Review Report on the fi rst half year fi nancial information

To the Shareholders,

In compliance with the assignment entrusted to us by your annual general meetings and in accordance with the requirements of article L. 451-1-2 of the French Monetary and Financial Code («Code monétaire et fi nancier»), we hereby report to you on :

the review of the accompanying condensed half-year consolidated fi nancial statements of GDF SUEZ, for the period from January 1 to June 30, 2011, and
the verifi cation of the information contained in the half-year management report.

These condensed half-year consolidated fi nancial statements were prepared under the responsibility of GDF SUEZ board of directors. Our role is to express a conclusion on these fi nancial statements based on our review.

1. CONCLUSION ON THE FINANCIAL STATEMENTS

We conducted our review in accordance with professional standards applicable in France. A review of interim fi nancial information consists in making inquiries, primarily of persons responsible for fi nancial and accounting matters, and applying analytical review procedures. A review is substantially less in scope than an audit conducted in accordance with professional standards applicable in France. Consequently, the level of assurance we obtained about whether the condensed half-year consolidated fi nancial statements taken as a whole, are free of material misstatements is moderate, and lower than that obtained in an audit.

Based on our review, nothing has come to our attention that causes us to believe that these condensed half-year consolidated fi nancial statements are not prepared in all material respects in accordance with IAS 34 – IFRS as adopted by the European Union applicable to interim fi nancial information.

2. SPECIFIC VERIFICATION

We have also verifi ed the information provided in the interim management report commenting on the condensed half-year consolidated fi nancial statements that were the object of our review.

We have no matters to report on the fairness and consistency of this information with the condensed half-year consolidated fi nancial statements.
