NOTES TO THE SEPARATE
FINANCIAL STATEMENTS

Notes to the Separate Financial Statements

ACCOUNTING PRINCIPLES AND VALUATION CRITERIA
Content and Format of the Financial Statements

Dear Shareholders:

We submit for your approval the separate financial statements of Edison Spa at December 31, 2009,
which consist of a balance sheet, an income statement, a statement of cash flows, a statement of
changes in shareholders’ equity and the accompanying notes.
The financial statements were prepared in accordance with the International Financial Reporting
Standards (IFRS) issued by the International Financial Accounting Standards Board (IASB), as published
in the Official Journal of the European Union (OJEU).

In particular, with effect from January 1, 2009, some international accounting principles have been
amended. However, none of these amendments had a material impact on the financial statements of
Edison Spa. Specifically:

• IAS 23 revised, which no longer allows the alternative treatment with regard to the capitalization of
borrowing costs (method used by Edison Spa until December 31, 2008). As a result, starting on
January 1, 2009, borrowing costs directly attributable to the acquisition, construction or production
of an asset must be capitalized when a significant period of time is required before the asset can
be ready for its intended use or for sale. At December 31, 2009 the impact on the Edison Spa
financial statements equal to 63 millions euros, is not material.
• IAS 1 revised, which introduces new disclosure requirements provided by means of a schedule
showing “Other Components of the Comprehensive Income Statement.” This schedule, which
supplements the income statement, lists the result components provisionally recognized in equity,
such as the change in the cash flow hedge reserve and the result from available-for-sale financial
assets. Previously, information about any changes in these components could only be gleaned by
analyzing the respective equity reserves.
• IFRS 8 “Operating Segments,” which replaces IAS 14 “Segment Reporting.” The required disclosure has
been expanded to include an analysis of the products and services supplied by the enterprise and, if
applicable, about major customers. This principle is not applicable to the separate financial statements.
• Revision of IFRS 2 “Share-based Payments,” which introduces changes regarding a plan’s vesting
period conditions and the accounting treatment of cancellations.
• Certain amendments to IAS 39 and IFRS 7, mainly concerning fair value measurement and liquidity
disclosures.
• IFRIC 13 “Customer Loyalty Programs” and IFRIC 14 “The Limit on a Defined Benefit Plan Asset,
Minimum Funding Requirements and their Interaction.”

Information about international accounting principles applicable in subsequent years is provided in the
Consolidated Financial Statement.

The publication of these separate financial statements was authorized by the Board of Directors on
February 8, 2010.

The separate financial statements were audited by PricewaterhouseCoopers in accordance with a three-
year assignment (from 2005 to 2008) it received from the Shareholders’ Meeting of April 19, 2005.
On April 5, 2008, the assignment awarded to the abovementioned Independent Auditors was extended
up to the approval of the financial statements at December 31, 2010.
Unless otherwise stated, the amounts that appear in the Notes to the Separate Financial Statements
are in thousands of euros.



Presentation Formats of the Financial Statements
The presentation formats chosen by Edison Spa for its financial statements incorporate the changes
required by the adoption of “IAS 1 Revised.” They have the following characteristics:

• In the Balance Sheet assets and liabilities are analyzed by maturity. Current and non-current items,
which are due within or after 12 months from the balance sheet date, respectively, are shown
separately.
• The Income Statement is a step-by-step income statement.
• The Other Components of the Comprehensive Income Statement list the result components
provisionally recognized in equity.
• The Statement of Cash Flows shows the cash flows in accordance with the indirect method, as
allowed by IAS 7.
• The Statement of Changes in Shareholders’ Equity included in the separate financial
statements shows separately the flows from cash flow hedge transactions and available-for-sale
investments.



Valuation Criteria

Property, Plant and Equipment and Investment Property
Property, plant and equipment used in the production process are classified as “Property, plant and equipment.”
Land and buildings that are not used in the production process are classified as “Investment property.”
In the financial statements, these assets are shown at purchase or production cost, or at their conveyance
value, including any attributable incidental costs and direct costs deemed necessary to make them
operable, net of any capital grants.
Individual components of a facility that have different useful lives are recognized separately, so that
each component may be depreciated at a rate consistent with its useful life. Under this principle, the
value of a building and the value of the land over which it has been erected are recognized separately
and only the building is depreciated.
Any costs that the Group expects to incur in the decommissioning of industrial sites are recognized as
an amortizable asset component. The value at which these costs are recognized is equal to the present
value of the costs that the Group expects to incur in the future.
Scheduled maintenance costs are charged in full to income in the year they are incurred.
Costs incurred for major maintenance that is performed at regular intervals are added to the respective
assets and are written off over the remaining useful lives of the assets.
The estimated realizable value that the Group expects to recover at the end of an asset’s useful life is
not depreciated. Property, plant and equipment is depreciated each year on a straight-line basis at rates
based on technical and financial estimates of the assets’ remaining useful lives.

The range of depreciation rates applied is shown below:

Electric Power Hydrocarbons Corporate
min. max min. max min. max
Buildings 4.0% 11.1% - 15.6% - 2.0%
Plant and machinery 4.0% 20.0% 1.7% 40.2% 5.3% 25.6%
Manifacturing and distribution equipment 5.0% 10.0% 17.5% 35.0% 5.0% 25.0%
Other assets 6.0% 20.0% 6.0% 25.0% 6.0% 20.0%
Investment property - - - - 2.0% 2.4%

Items of property, plant and equipment appurtenant to hydrocarbon production concessions and the costs
incurred to close well, abandon the site and decommission or remove equipment are recognized as assets
and depreciated in accordance with the UOP method, which is also used to amortize the underlying concessions.
Accordingly, depreciation is computed on the value determined by the ratio between the quantities produced
during the year and the estimated remaining available reserves at the beginning of the year.
The depreciation method applied to thermoelectric power plants that sell energy under the CIP 6/92
rate schedule, which is based on the economic benefits produced, follows a step-down process, with
straight line depreciation for each of the periods. This method reflects the differences between the
amounts charged under the CIP 6/92 rate schedule for the 8-year incentivized period and the following
7-year contract period and the market terms applicable after the CIP 6/92 contract expires.
The depreciation of assets transferable free of charge is taken on a straight-line basis over the remaining
term of the respective contracts or their estimated useful lives, whichever is less.
Assets acquired through financial leases must be booked under property, plant and equipment, with an
offsetting entry of equal amount made to loans payable. The liability is gradually eliminated in accordance
with the principal repayment schedule of the respective lease agreement. The value of the asset is
depreciated on a straight-line basis, based on technical and financial estimates of its useful life.
Upon initial adoption of the IAS/IFRS principles, the Company used fair value as deemed cost. As a
result, accumulated depreciation and amortization and the provision for writedowns booked through
January 1, 2004 were derecognized. The accumulated depreciation and amortization and the provision



for writedowns discussed in the notes to the financial statements refer exclusively to depreciation,
amortization and writedowns that accumulated after January 1, 2004.
If there are indications of a decline in value, assets are subjected to an impairment test in the manner
described below under Impairment of Assets. When the reasons for a writedown no longer apply, the
asset’s cost is reinstated.
Beginning on January 1, 2009, borrowing costs directly attributable to the acquisition, construction or
production of an asset must be capitalized when a significant period of time is required before the asset
can be ready for its intended use or for sale. Until December 31, 2008, borrowing costs were not capitalized.

Goodwill
Goodwill acquired for consideration, which for transition purposes had been recognized at the same
amount as in the statutory financial statements at December 31, 2003, and other intangible assets with
indefinite useful lives are not amortized on a straight-line basis, but the recoverability of the carrying
amounts is checked annually (impairment test) for each Cash Generating Unit (CGU) or group of CGUs
to which assets with indefinite lives can be reasonably allocated. The impairment test is described below
in the section entitled Impairment of Assets. When the reasons for a writedown no longer apply, the
asset’s cost is not reinstated.
The decision to take the conservative approach of using for the transition to the IAS/IFRS principles
on January 1, 2004 the same values as those used in the statutory financial statements prepared in
accordance with Italian accounting principles is justified by the uncertainty that currently exists with
respect to the accounting treatment that should be applied to these assets in the separate financial
statements prepared in accordance with the IAS/IFRS principles.

Hydrocarbon Concessions and Other Intangible Assets
Only identifiable assets that are controlled by the Company and are capable of producing future benefits
can be identified as intangible assets. Intangibles are recorded at purchase or internal production cost,
including incidentals, in accordance with the same criteria used for property, plant and equipment.
Development costs can be capitalized, provided they can be identified reliably and it can be demonstrated
that the asset is capable of producing future economic benefits.
Intangible assets with finite useful lives are amortized on a straight-line basis over their useful lives,
starting when they are available for use.
The costs incurred to acquire mineral leases or extend the duration of existing permits are recognized
as intangible assets. If an exploration project is later abandoned, the residual cost is charged immediately
to income.
Exploration costs and costs incurred in connection with geological surveys, exploratory testing, geological
and geophysical mapping and exploratory drilling are recognized as intangible assets but their full
amount is amortized in the year they are incurred.
Development costs related to successful mineral wells and production costs incurred to build facilities
to extract and store hydrocarbons are recognized as property, plant and equipment, depending on the
type of asset, and are depreciated in accordance with the unit-of-product (UOP) method.
The costs incurred to close mineral wells, clear the well areas and dismantle or remove structures are
recognized as assets and amortized in accordance with the UOP method.
Exploration and production activities in which Edison is the operator or the venturer are recorded only
for the own interest in the activities and/or operations.
Hydrocarbon production concessions are amortized in accordance with the unit-of-product method.
The amortization rate is computed on the value determined by the ratio between the quantities produced
during the fiscal year and the estimated remaining available reserves at the beginning of the fiscal year,
taking into account any significant change to reserves that occurred during the fiscal year. In addition,
a test is conducted each year to make sure that the carrying amounts of these assets are not greater
than their realizable value computed by discounting future cash flows, which are estimated based on
future production programs and market values.

2009 Annual Report I 11


Environmental Securities (Emissions Rights and Green Certificates)
Edison Spa secures a supply of environmental securities (emissions rights and green certificates) to
meet its own requirements in the exercise of its industrial activities (so-called “own use”).
Specifically, other intangible assets can include emissions rights and green certificates, which are
recognized at the cost incurred to acquire them if the rights or certificates carried by the Company on
the balance sheet date exceed its requirements of such instruments, based on the emissions released
during the year, for the emissions rights, or the production generated, for the green certificates. Emissions
rights and green certificates allocated free of charge are recognized at a zero carrying value. Since
these assets are designed for instantaneous use, they are tested for impairment and cannot be amortized.
Their recoverable value is their value in use or their market value, whichever is greater. On the other
hand, if, on the balance sheet date, the value of the actual emissions is greater than the value of the
allocated emissions, including any purchased emissions, a special provision for risks is set aside to cover
the difference. Any emissions rights and certificates that are turned back each year, based on the volume
of polluting emissions released into the atmosphere each year or the production generated, will be
deleted using any reserves for risks set aside the previous year.

Equity Investments in Subsidiaries and Affiliated Companies
Subsidiaries are companies with respect to which Edison has the power independently to make strategic
corporate decisions for the purpose of obtaining the resulting benefits. As a rule, control is presumed
to exist when the controlling company holds, directly or indirectly, more than half of the votes that can
be cast at an Ordinary Shareholders’ Meeting, also counting the so-called “potential votes” (i.e., votes
conveyed by convertible instruments).
Affiliated companies are companies with respect to which Edison exercises a significant influence over
the process of making strategic corporate decisions, even though it does not have control, when the
so-called “potential votes” (i.e., votes conveyed by convertible instruments) are counted. A significant
influence is presumed to exist when the controlling company holds, directly or indirectly, more than 20%
of the votes that can be cast at an Ordinary Shareholders’ Meeting.
Equity investments in subsidiaries and affiliated companies are valued at cost, written down to reflect
any distributions of share capital or equity reserves or any impairment losses discovered as a result of
an impairment test. If the reasons that justified the writedown cease to apply in subsequent years, the
original cost is reinstated.

Impairment of Assets
IAS 36 requires that an entity test its property, plant and equipment and intangible assets for impairment
when there are indications that an impairment has occurred.
In the case of goodwill and other assets with indefinite lives or assets that are not available for use, the
impairment test must be conducted annually.
The recoverability of a carrying amount is tested by comparing it against an asset’s fair value, less cost
to sell, when there is an active market, or its value in use, whichever is greater.
As a rule, value in use is the present value of future cash flows expected to be derived from an asset
or a CGU and from its disposal at the end of its useful life.
CGUs, which have been identified in a way that is consistent with the Edison’s organizational and
business structure, are homogeneous groups of assets that generate cash inflows independently, through
the continued use of the assets included in each group.

Translation of Items Denominated in Foreign Currencies
Transactions in foreign currencies are translated into euros at the exchange rate in force on the transaction
date. At the end of the year, cash assets and liabilities are translated at the exchange rates in force on
the balance sheet date. Any resulting foreign exchange translation differences are recognized in earnings.
Non-cash assets and liabilities denominated in foreign currencies are valued at cost and translated at
the exchange rates in force on the transaction date.



Financial Instruments
Financial instruments include equity investments (other than investments in subsidiaries and affiliate
companies) that the Company plans to sell, such as trading investments and available-for-sale investments.
They also include long-term loans and receivables, trade receivables and other receivables generated
by the Company, and current financial assets, such as cash and cash equivalents. Cash and cash
equivalents include bank and postal deposit accounts, readily marketable securities purchased as
temporary investments of cash and loans receivable due within three months. This item also includes
loans payable, trade and other payables, other financial liabilities and derivatives.
Financial assets and liabilities are recognized in the accounting records at fair value when the Company
acquires the contractual rights and obligations conveyed by the underlying financial instrument.
The initial amount at which financial instruments are recognized should include the directly attributable
transaction costs incurred upon purchase or the issuance costs that are included in the initial valuation
of all those assets and liabilities that can be classified as financial instruments. Subsequent measurements
will depend on the type of instrument, as follows:
• With the exception of derivatives, assets held for trading are valued at fair value, and any resulting
gains or losses are recognized in the income statement. This class of assets consists mainly of
trading securities.
• Provided they are not derivatives and equity investments, other financial assets and liabilities with
fixed or determinable payments and fixed maturities are valued at their amortized cost.
Purchasing/Selling costs (e.g., issue premiums or discounts, the costs incurred to secure loans, etc.)
are posted directly as adjustments to the face value of the corresponding asset or liability. Financial
income and expense are computed in accordance with the effective interest rate method. The value
of financial assets is assessed on a regular basis to determine if there is any objective evidence that
their value may have been impaired. More specifically, the valuation of receivables takes into account
the solvency of creditors and the level of credit risk, which is indicative of individual debtors’ ability to
pay. Any losses are recognized in the income statement for the corresponding period. This category
includes long-term loans and receivables, trade receivables and other receivables generated by the
Company, as well as loans payable, trade and other payables and other financial liabilities.
• Available-for-sale assets are valued at fair value and any resulting gains or losses are recognized
in equity until disposal, when they are transferred to the income statement. Losses that result from
measurement at fair value are recognized directly in earnings when there is objective evidence that
the value of a financial asset has been impaired, even though the asset has not been sold. Equity
investments in companies that are not publicly traded, the fair value of which cannot be measured
reliably, are valued at cost less impairment losses, but the original cost can be reinstated in
subsequent years if the reasons for the writedowns are no longer applicable. This category also
includes equity investments representing an interest of less than 20%.
• Derivatives are recognized at their fair value. Changes in fair value are recognized in earnings when
a derivative does not qualify as a hedging instrument because of the type of instrument or because
the Company elects not to perform the effectiveness test. Derivatives can be classified as hedges
when the relationship between the derivative and the hedged item is formally documented and the
effectiveness of the hedge, which must be tested periodically, is high pursuant to IAS 39. When
derivatives hedge the risk of fluctuations in the cash flow of the hedged items (cash flow hedge),
the effective portion of any change in the fair value of the derivatives is recognized directly in equity,
while the ineffective portion is recognized directly in earnings. The amounts recognized in equity are
transferred to the income statement in conjunction with the gains or losses generated by the
hedged item. When derivatives hedge the risk of changes in the fair value of the hedged items (fair
value hedge), any changes in the fair value of the derivatives are reflected directly in earnings. The
carrying value of the hedged items is adjusted accordingly, to reflect changes in fair value
associated with the hedged risk.
Financial assets are derecognized when they no longer convey the right to receive the related cash
flows and substantially all of the risks and benefits conveyed by the ownership of the assets have been



transferred or when an asset is deemed to be totally non-recoverable after all necessary recovery
procedures have been carried out.
Financial liabilities are removed from the balance sheet when the corresponding contractual obligations
have been satisfied.
The fair value of financial instruments that are traded on an active market is based on their market price
on the date of the financial statements. The fair value of financial instruments that are not traded on
an active market is determined using appropriate valuation techniques.

Inventories
Inventories are valued at the lesser of purchase or production cost, including incidental expenses, or
estimated realizable value, based on market conditions. Cost is determined primarily by the FIFO method.

Employee Benefits
The provision for employee severance indemnities and the provision for pensions are computed
on an actuarial basis. The value of benefits due to employees who have become vested during the year
is charged to income under labor costs. The theoretical finance charge that the Company would incur
if it were to borrow in the marketplace an amount equal to the provision for employee severance
indemnities is posted to financial income (expense). Actuarial gains and losses that arise from changes
in the actuarial assumptions used are reflected in the income statement, taking into account the average
working lives of the employees.
Specifically, in accordance with Budget Law No. 296 of December 27, 2006, only the liability for the
vested employee severance benefits that remained at the Company was valued for IAS 19 purposes,
since the portion applicable to future vesting benefits is being paid to separate entities (supplemental
pension funds or INPS funds). As a result of these payments, the Company has no further obligations
with regard to the work that employees will perform in the future (defined-contribution plans).
Stock option plans are valued at the time the options are awarded by determining the fair value of
the option rights issued. This value, net of any subscription costs, is allocated over the plan’s vesting
period. The corresponding cost is recognized in earnings, with an offsetting entry posted to an equity
reserve (equity settled payments).

Provision for Risks and Charges
Provision for risks and charges are established exclusively to fund reliable estimate of current
obligations that arise from past events. These obligations can be legal or contractual in nature or can
be the result of representations or actions of the Company that create valid expectations in the relevant
counterparties that the Company will be responsible for complying or will assume the responsibility of
causing others to comply with an obligation (implied obligations). If the time value of money is significant
the net present value of the provision is recorded in the financial statement.

Recognition of Revenues and Expenses
Revenues and income and costs and expenses are reflected in the financial statements net of
returns, discounts, allowances, bonuses and any taxes directly related to the sale of products or the
provision of services. Sales revenues are recognized when title to the goods passes to the buyer. As a
rule, this occurs when the goods are delivered or shipped. The cost of materials used includes the costs
incurred for green certificates and emissions rights attributable to the year. Financial income and expense
is recognized when accrued. Dividends are recognized when the shareholders are awarded the rights
to collect them, which generally occurs in the year when the disbursing investee company holds a
Shareholders’ Meeting that approves a distribution of earnings or reserves.

Income Taxes
Income taxes for the fiscal year are determined on the basis of its taxable income, computed in
accordance with the tax rates and laws that have been enacted or substantively enacted by the balance



sheet date and taking into account any applicable exemptions or available tax credits.
Deferred-tax assets and liabilities are computed on the temporary differences between the values
attributed to assets and liabilities for statutory and tax purposes, using the tax rates that are expected
to be in force when the temporary differences are reversed. Deferred-tax assets are recognized only
when their future recovery is reasonably certain. Otherwise, their value is written down. The valuation
of deferred-tax assets must be carried out taking into account future tax liabilities, as projected in
approved Company industrial plans. When gains and losses are recognized directly in equity, the
corresponding deferred-tax assets or liabilities must also be reflected under shareholders’ equity.

Use of Estimated Values
The preparation of the financial statements and the related notes requires the use of estimates and
assumptions both in the measurement of certain assets and liabilities and in the valuation of contingent
assets and liabilities. The actual results that arise upon the occurrence of the relevant events could thus
differ from these estimates.
The estimates and assumptions used are revised on an ongoing basis, and the impact of any such
revision is immediately recognized in profit or loss. The use of estimates is particularly significant for
the following items:
• Amortization of intangible assets with a finite useful life and impairment tests of property, plant and
equipment, goodwill and other intangible assets. The process of determining depreciation and
amortization expense entails reviewing periodically the remaining useful lives of assets, the available
hydrocarbon reserves, the decommissioning/shut down costs and the assets’ recoverable value.
Information about the impairment test is provided in the section of these Notes entitled “Impairment
Test Applied to the Value of Goodwill, Property, Plant and Equipment and Other Intangibles,” which
includes a description of the methods and assumptions used.
• Valuation of derivatives and financial instruments in general. Information about valuation criteria was
provided earlier in this section of these Notes to the Financial Statements, while quantitative
disclosures may be found elsewhere in these Notes to the Financial Statements, which supplement
and accompany the financial statements. The methods applied to determine the fair value of and the
risks inherent in energy commodities traded by the Companies, foreign exchange rates and interest
rates are described in the “Risk Management” section of these Notes to the Financial Statements.
• Measurement of certain sales revenues, in particular referring to CIP 6/92 agreement, the provisions
for risks and charges, the allowances for doubtful accounts and other provisions for writedowns,
employee benefits and income taxes. In these cases, the estimates used are the best estimates
possible, based on currently available information.



FINANCIAL RISK MANAGEMENT
As required by IFRS 7, the paragraphs that follow provide information about the nature of risks concerning
Edison Spa, the Group’s Parent Company. Information about the policies and principles adopted to
manage these risks and the methods applied to measure at fair value the financial derivatives held by
Edison Spa is provided in the Consolidated Financial Statements.

Commodity Price Risk and Exchange Rates Risk Related to Commodity
Transactions
Edison Spa is affected by the risk of fluctuations in the prices of all of the energy commodities that it
handles (electric power, natural gas, coal, petroleum products and environmental securities) because
they have an impact on the revenues and costs of its production, storage and buying and selling activities.
These fluctuations affect the Company both directly and indirectly through indexing mechanisms
contained in pricing formulas. Moreover, because some of the abovementioned commodity prices are
quoted in U.S. dollars, Edison Spa is also exposed to the resulting exchange rate risk.

Insofar as the derivatives held by the Group’s Parent Company that were outstanding at December 31,
2009 are concerned, the maximum negative variance in the fair value of financial instruments expected,
over the time horizon of the current year, with a 97.5% probability, compared with the fair value determined
at December 31, 2009, is 89.1 million euros (205 million euros at December 31, 2008), as shown in
the table below:

(in millions of euros) 12/31/2009 12/31/2008
Level of Expected Level of Expected
probability negative variance probability negative variance
in fair value in fair value
Edison Spa 97.5% 89.1 97.5% 205.0

In other words, compared with the fair value determined for the financial contracts outstanding at
December 31, 2009, the probability of a negative variance greater than 89.1 million euros by the end
of 2010 is limited to 2.5% of the scenarios.
The decrease compared with the level measured at December 31, 2008 is due primarily to a reduction
in the total volume of financial contracts outstanding, as well as to different monthly profiles of the
contracts.

Foreign Exchange Risk not Related to Commodity Risk
With the exception of the issues reviewed above in the paragraph that discusses the commodity risk,
Edison Spa does not have a significant exposure to currency risks.

Interest Rate Risk
Edison Spa is exposed to fluctuations in interest rates primarily because they affect its debt service
costs. The Group’s main interest rate exposure is to the Euribor.

without with % with without with % with
derivatives derivatives derivatives derivatives derivatives derivatives
- fixed rate portion 1,401 551 13% 702 911 36%
- variable rate portion 2,697 3,547 87% 1,798 1,589 64%

(*) For the composition of gross borrowings see also the table in the “Liquidity Risk” section of this Report.



As shown by the breakdown in the preceding table, at December 31, 2009, Edison’s exposure to the
risk of changes in interest rates was equivalent to about 87% of its total gross exposure (64% at
December 31, 2008). The remaining 13% at fixed rates (36% at December 31, 2008), is the combined
result of borrowings originally structured with a fixed rate and derivatives executed to hedge bank
borrowings or bonds payable that are contractually indexed to a variable rate.

Most derivate transactions refer to the following bond issues, which constitute the most stable source
of financing (for the main characteristics of the outstanding bond issues, see the table provided later
in this Report in the following section entitled “Default Risk and Debt Covenants”):
• the interest rate on a portion (350 million euros) of a 700-million-euro bond issue, that matures in
December 2010, was changed from a 5.125% fixed rate to a variable rate;
• the fixed interest rate (4.25%) on a portion (500 million euros) of a new 700-million-euro bond
issue floated in July 2009 was changed to a variable interest rate, using interest swaps that are
accounted for in accordance with the fair value hedge method;
• the transactions that hedged 500 million euros in bonds, maturing in July 2011, by converting to a
fixed rate the interest rate on 200 million euros and applying to the remaining 300 million euros a
structure that prevented the contractual interest rate from rising above 3.95% were closed out on
July 20, 2009.

The table below provides a sensitivity analysis that shows the impact on the income statement
(P&L) and shareholders’ equity (S/E) of a hypothetical shift of the forward curve of plus or minus
50 basis points compared with the rates actually applied in 2009 and provides a comparison with
the previous year.

Credit Risk
The credit risk represents Edison’s exposure to potential losses that could be incurred if a commercial
or financial counterpart fails to meet its obligations. This risk arises primarily from economic/financial
factors (i.e., that the counterpart defaults on its obligations), as well as from factors that are
technical/commercial or administrative/legal in nature (disputes over the type/quantity of goods supplied,
the interpretation of contractual clauses, supporting invoices, etc.).
In addition, during the year, Edison executed transaction assigning receivables without recourse on a
revolving and spot basis for a total amount of 1.235 million of euros. At december 31, 2009, the risk
of recourse that still existed on these transactions was not material.

The table that follows shows an overview of gross trade receivables, the corresponding allowance for
doubtful accounts and the guarantees that the Group holds to secure its receivables. The decrease in
receivables outstanding at December 31, 2009, compared with the balance a year earlier, is largely due
to changed conditions in the international scenario, which caused a reduction in fuel prices, with an
attendant decrease in revenue amounts.

Trade receivables 976 1,617

Receivables 9 to 12 months in arrears 2 6
Receivables more than 12 months in arrears 41 10

Trade receivables that are delinquent on the balance sheet date are offset by corresponding allowances.

Liquidity Risk
The liquidity risk represents the risk that the Company may not have access to sufficient financial
resources to meet its financial and commercial obligations in accordance with agreed terms and
maturities. The table that follows provides a worst-case scenario - showing undiscounted nominal
future cash flows, both for principal and accrued interest, required for financial liabilities, including
trade accounts payable and interest rate derivatives - in which assets (cash and cash equivalents,
trade receivables, etc.) are not taken into account and financing facilities are treated as if repayable
on demand, in the case of revocable lines of credit, or on the first due date when repayment can be
demanded, in other cases.

(*) Guarantees are shown based on the remaining contractual maturity. They refer to commercial transactions related to operating activity.

The Company’s strategic objective is to minimize the impact of financial debt maturities by maintaining
access to existing credit lines and adequate liquidity and implementing on a timely basis negotiations
for the funding of maturing financing facilities. As for the composition of the short-term financial debt,
810 million euros of which is due within a year, offset by 567 million euros in liquid assets, the main
component (736 million euros) is represented by Edison Spa bonds (5.125% fixed interest rate) with
a face value of 700 million euros issued in 2003. In any case, at December 31, 2009, Edison had access
to unused committed lines of credit amounting to 850 million euros, provided by a standby credit line
of 1,500 million euros that expires in 2013. A total of 650 million euros has been drawn against this
credit line, which is shown under financial debt due after one year in the table above.

At the end of May 2009 Edison Spa signed a three-year agreement for a 600-million-euro loan with
a pool of Italian and international banks, which is structured as a non-syndicated facility provided on a
club-deal basis. This facility, which consists of Senior Unsecured Term Loan, is repayable in a lump sum
in May 2012 and accrues interest at a rate indexed to the Euribor.

The table below provides a breakdown by maturity of Edison’s gross borrowings at December 31, 2009.
However, the amounts shown are not accurately indicative of the exposure to the liquidity risk in that
they do not reflect expected nominal cash flow, using instead amortized cost valuations and the fair
value of derivatives, or the amounts at which financial liabilities were recognized in the accounting
records at December 31, 2009.



Lastly, the 650 million euros drawn against the 1,500-million-euro standby facility is shown in the table
below based on the maturity of the underlying facility (April 2013), considering it a part of medium/long-
term funding sources, based also on the funding requirements of the industrial plan.

Default Risk and Debt Covenants
This type of risk arises from the possibility that loan agreements or bond indentures to which Edison
Spa is a party may contain provisions that, if certain events were to occur, would empower the lenders,
be they banks or bondholders, to demand that the borrower repay immediately the loaned amounts,
which, consequently, would create a liquidity risk (see the “Liquidity Risk” section above).
Three issues of debt securities (Euro Medium-term Notes), for a total face value of 1,900 million euros,
are outstanding (see table below, in millions of euros):

Stock Exch. annual

In addition, Edison Spa is a party to non-syndicated loan agreements with a total face value of 229
million euros and syndicated loan agreements with a total face value of 2,100 million euro. A balance
of 850 million euros was unused at December 31, 2009.
Generally, consistent with international practice for financial transactions of this type, these agreements
provide the lenders with the right to demand the payment of the indebtedness and terminate their
relationship with the borrower whenever the borrower is declared insolvent and/or is a party to bankruptcy
proceedings (such as receivership or composition with creditors) or is undergoing liquidation or another
procedure with similar effects.
Specifically, the bond indentures, consistent with market practices, include a series of standard clauses
that, in the event of non-performance, require that the issuer immediately redeem the bonds. The main
clauses of this type are: (i) negative pledge clauses, by virtue of which the borrower undertakes to refrain
to provide Company assets as collateral beyond a specific amount; and (ii) cross default/cross acceleration
clauses, which establish an obligation to immediately repay the bonds in the event of material failures
to perform obligations that arise from or are generated by other loan agreements that affect a significant
portion of the indebtedness owed by the Company.
As for credit line agreements and bilateral or syndicated loan agreements to which Edison is a party, it
is important to note that the agreement for a syndicated credit line of 1,500 million euros provided to
Edison sets forth, among other clauses, Edison’s obligation to comply with certain commitments, which
include making sure that the lender banks are being afforded a treatment equal to the one offered
under other unsecured loan agreements, as well as restrictions on Edison’s ability to provide collateral
to new lenders (negative pledge clause).



Similar commitment are included in the loan agreement for the 600-million-euro facility provided to
Edison, in May 2009, by a pool of Italian and international banks on a Club Deal basis. In this case, in
addition to the obligations and restrictions mentioned above, the loan agreement also sets forth
requirements concerning compliance with financial ratios (financial covenants). Specifically, the ratio of
EBITDA to financial expense and the ratio of net financial debt to EBITDA must be neither higher nor
lower, respectively, than predetermined thresholds. The threshold levels were determined conservatively,
based on the Group’s industrial plan.

At present, the Company is not aware of any situation that would cause it to be in default or in violation
of any of the abovementioned covenants.



Analysis of Forward Transactions and Derivatives
Whenever possible, the Company uses hedge accounting to recognize derivative contracts executed
to hedge the risk of fluctuations in the prices of energy commodities and in the relevant foreign exchange
parities, as well as the risk of interest rate volatility, as it applies to its indebtedness, provided the
corresponding transactions comply with the requirements of IAS 39.

Derivatives transactions can be classified as follows:
1) Transactions that qualify as hedges in accordance with IAS 39: This category includes cash
flow hedges and fair value hedges. More specifically:
a. In the case of Cash Flow Hedges (CFH), realized results are either included in EBITDA, for
commodity transactions, or recognized as financial income or expense, for financial transactions.
The effective portion of the expected value is reflected in a special reserve of shareholders’
equity and the changes that occurred in this reserve during the year are analyzed in the
disclosures about “Other Components of the Comprehensive Income Statement.” The ineffective
portion is recognized in profit or loss.
b. In the case of Fair Value Hedges (FVH), which at this point refer only to a portion of the
fixed-rate bonds issued in July 2009, both the fair value of the derivatives (expected value)
and the realized result are recognized in profit or loss.

2) Transactions that do not qualify as hedges in accordance with IAS 39, which are used to manage
interest rate and foreign exchange risks on energy commodities. For all hedging transactions that
comply with internal risk policies and procedures, realized results and expected value are either
included in EBITDA, if they refer to activities related to the industrial portfolio, or recognized as
financial income or expense, in the case of financial transactions.

Fair Value Hierarchy according to IFRS 7
IFRS 7 identifies a fair value hierarchy to rank the reliability of inputs used in a valuation approach of
fair value.
The IFRS 7 ranking is based on the following hierarchy:

• Level 1: Determination of fair value based on quoted prices (unadjusted) for identical assets or
liabilities in active markets. There were no instruments ranked Level 1 at December 31, 2009.
• Level 2: Determination of fair value based on inputs other than the quoted prices of Level 1 but
which are directly or indirectly observable. This category includes instruments with which the
Company operates in over-the-counter markets that are insufficiently liquid or do not generate
binding market quotes on a continuing basis. It also includes instruments with which Edison
operates in markets ranked at “Level 1” the fair value of which is determined by models with
unobservable input or market-based input (e.g., swaps based on futures markets, the valuation of
which depends on futures prices, the interest rate and the remaining days to delivery).
• Level 3: Determination of fair value based on valuation models with inputs not based on observable
market data (unobservable inputs). There were no instruments ranked Level 3 at December 31, 2009.

The ranking of financial instruments can entail significant subjective judgment. However, as required
by IFRS 7, Edison uses prices quoted in active markets, when available, as the best estimate of the fair
value of all derivatives.



Instruments Outstanding at December 31, 2009
The tables that follow provide an illustration of the information listed below:
• Fair value rank applied;
• Derivatives that were outstanding, classified by maturity;
• The value at which these contracts are reflected on the balance sheet, which is their fair value.
• The pro rata share of the fair value referred to above that was recognized on the income statement
from the date of execution.

The difference, if any, between the value on the balance sheet and the fair value recognized on the
income statement is the fair value of contracts that qualify as cash flow hedges, which, in accordance
with the reference accounting principles, is posted directly to equity reserves.

Classes of Financial Instruments
The table provided below, which lists the types of financial instruments recognized in the financial
statements showing the valuation criteria applied and, in the case of financial instruments measured at
fair value, whether gains or losses were recognized in earnings or in equity, completes the disclosures
required by IFRS 7. The last column in the table shows, if applicable, the fair value of financial instruments
at December 31, 2009.
Edison has chosen not to adopt the value option and, consequently, as the table shows, neither borrowings
nor bonds were restated at fair value.

The total value of these assets includes “Construction in progress and advances” totaling 135,843,000
euros, attributable mainly to the repowering of some power plants (38,696,000 euros), and the development
of some hydrocarbon fields (about 56,064,000 euros).

Additions include the following:
• 133,648,000 euros invested by the electric power operations in projects to repower the
Marghera Azotati thermoelectric power plant (46,276,000 euros), the Bussi thermoelectric power
plant (12,981,000 euros) and some hydroelectric power plants (23,526,000 euros).
• 68,762,000 euros invested by the hydrocarbons operations mainly in connection with the finance
lease for the Leonis ship, a floating storage, acquired for the Vega field supporting the hydrocarbon
operations.

Disposals refer mainly to the sale of components from thermoelectric and hydroelectric power plants,
which generated total proceeds of about 12,441,000 euros.

Depreciation totaled 323,289,000 euros, for a decrease of 53,207,000 euros compared with 2008,
due mainly to the conveyance of business operations, consisting of five thermoelectric power plants
and 10 hydroelectric power plants, in 2008. In 2009, the residual value of some hydroelectric power
plants was restated with a positive effect of 13.865.000 euros. More detailed information about these
transactions is provided in the note to the corresponding income statement item.

Writedowns include charges of 7,382,000 euros to write down the carrying amount of two thermoelectric
power plants, 6,187,000 euros to restate the value of some gas fields and 1,500,000 euros to write
down some land that is currently the subject of expropriation proceedings.



The net carrying amount of property, plant and equipment also includes:
• Assets transferable at no cost valued at 127,057,000 euros (155,350,000 euros at December
31, 2008), attributable mainly to Edison’s hydroelectric operations, which hold directly 24
concessions (the same as at December 31, 2008).
A breakdown is as follows:

• Assets acquired under finance leases, which at December 31, 2009 referred exclusively to the
Leonis ship, acquired for the Vega field were recognized in accordance with the IAS 17 (revised)
method. The remaining financial liability under this lease was 30,733,000 euros.

3. Goodwill
Goodwill totaled 2,632,320,000 euros. The residual value of goodwill is an intangible asset with an
indefinite useful life. As such, it cannot be amortized in regular installments but must be tested for
impairment at least once a year. The method applied to determine the value of goodwill is consistent
with the criteria for allocation by business operations, which are set forth in the definition of cash
generating units provided in the Notes to the Consolidated Financial Statements.
An impairment test of goodwill showed that no writedowns were required.



4. Hydrocarbon Concessions
Concessions for the production of hydrocarbons include 47 hydrocarbon production leases in Italy. The
decrease of 18,804,000 euros compared with December 31, 2008 is the result of the amortization for
the period. The table below shows the balance in this account and the changes that occurred in 2009:

Balance at 12/31/2008 (A) 212,643
Changes in 2009:

(*) The amortization and the remaining life of mineral deposits is computed as a ratio of the quantity extracted to the available reserve.

5. Other Intangible Assets
The balance of 20,742,000 euros refers to patents, licenses and similar rights consisting mainly of
software licenses (16,713,000 euros) and work in progress (3,510,000 euros). Disposals refer mainly
to the divestment of an exclusivity right that generated proceeds of 959,000 euros.

Impairment Test Applied to the Value of Goodwill, Property, Plant and Equipment
and Other Intangibles
Because goodwill is an intangible asset with an indefinite useful life and, therefore, cannot be amortized
in regular installments, IAS 36 requires that its value be tested for impairment at least once a year. Since
goodwill does not generate cash flow independently and cannot be sold separately, IAS 36 requires a
test of the value that can be recovered on a residual basis. This is accomplished by determining the
cash flows generated by the complex of assets that constitute the business or businesses to which
goodwill is attributable (the cash generating unit or units - CGUs).
In 2009, the carrying amount of two thermoelectric power plants was written down by 7,400,000 euros to
reflect their recoverable value, in addition to other writedowns already mentioned referring to some gas fields
(6,187,000 euros) and some land (1,500,000 euros).

6. Investments in Associates and Available-for-sale Investments
The balance of 2,011,838,000 euros includes 880,194,000 euros in investments in subsidiaries and
1,131,644,000 euros in investments in joint ventures and affiliated companies. Available-for-sale
investments were valued at 302,988,000 euros. They include 286,444,000 euros for a 10% interest
in Terminale GNL, the company that owns the offshore regasification terminal near Porto Viro.

Abu Qir concession, in January, for 1,011 million euros.

Derivatives
This item refers in its entirety to the measurement at fair value of derivatives outstanding at December
31, 2008, which hedged interest rate and foreign exchange risks.
A comprehensive overview of the impact of derivatives is provided in a separate disclosure included
in the “Risk Management” section of this Report.

• Cash and cash equivalents, which totaled 567,253,000 euros, consist of short-term deposits in
bank and postal accounts and other readily available assets. The increase compared with the
beginning of the year is chiefly the result of working capital management strategies.

11. Assets held for sale
This account had a zero balance at December 31, 2009.



Liabilities and Shareholders’ Equity

12. Shareholders’ Equity
Edison’s shareholders’ equity amounted to 7,128,801,000 euros, for a net increase of 359.381,000
euros compared with December 31, 2008. This improvement is the result of the profit earned in 2009
(423.258,000 euros) and a positive change of 201,717,000 euros in the Reserve for cash flow hedge
transactions, offset in part by the distribution of dividends totaling 267,903,000 euros (equal to a dividend
of 0.05 euros per common share and 0.08 euros per savings share).

The main component of Other reserves is a reserve of 467,109,000 euros established in connection
with the adjustment to fair value as the deemed cost of property, plant and equipment upon transition
to the IFRSs.

The capital stock of Edison Spa consisted of shares with a par value of 1 euro each, regular ranking
for dividends. A breakdown is as follows:

Share class Number of shares Millions of euros
Common shares 5,181,108,251 5,181
Savings shares 110,592,420 111
Total 5,292

The table below shows the changes that occurred in the Reserve for cash flow hedge transactions
related to the adoption of IAS 32 and IAS 39 to value derivatives, most of which were executed to hedge
price and exchange rate risks related to energy commodities.

Reserve at December 31, 2009 49,601 (18,799) 30,802

The following changes occurred in the Reserve for available-for-sale investments:

- Changes in 2009 2,309 - 2,309
Reserve at December 31, 2009 (1,901) - (1,901)

13. Provision for Employee Severance Indemnities and Provisions
for Pensions
These provisions, which amounted to 29,560,000 euros, reflect the accrued severance indemnities and
other benefits owed to employees at December 31, 2009. A valuation in accordance with the criteria
of IAS 19 was performed only for the liability corresponding to the provision for employee severance
indemnities that is still held by the Company.

The economic and financial parameters used for valuation purposes are listed below:
- Technical annual discount rate 4.60%
- Annual inflation rate 2.00%



The table below shows the changes that occurred in 2009:

Balance at 12/31/2008 (A) 30,982
Changes in 2009:
- Utilizations (-) (1,839)
- Service costs (+) -
- Actuarial (gains) losses (+/-) (1,008)
- Financial expense (+) 1,425
Balance at 12/31/2009 (A+B) 29,560

14. Provision for Deferred Taxes
The balance of 301,868,000 euros, which is net of offsettable deferred-tax assets, reflects mainly the
deferred-tax liability from the use during transition to the IFRSs of fair value as the deemed cost of
property, plant and equipment.

As explained in detail later in this Report, in the note on Income taxes, the change in deferred-tax
liabilities reflects the increase of one percentage point in the rate of the “Robin Hood Tax.”

Since these provisions met the requirements of IAS 12, they were offset against the Deferred-tax assets
account. The table below shows a breakdown of these provisions:

Deferred-tax liabilities:
- Differences in the valuation of property, plant and equipment 304,953 350,928 (45,975)
- Adoption of the standard on finance leases (IAS 17) 28,305 28,183 122
- Adoption of the standard on financial instruments (IAS 39)
with impact on:
- the income statement - - -
- shareholders' equity 18,799 - 18,799
- Other deferred taxes 416 3,475 (3,059)
Total deferred-tax liabilities (A) 352,473 382,586 (30,113)

Deferred-tax assets available for offsetting purposes:
- Taxed provisions for risks 49,230 38,840 10,390
- Adoption of the standard on financial instruments (IAS 39)
with impact on:
- the income statement 592 2,222 (1,630)
- shareholders' equity - 99,924 (99,924)
- Other prepaid taxes 783 631 152
Total deferred-tax assets (B) 50,605 141,617 (91,012)
Total provision for deferred taxes (A-B) 301,868 240,969 60,899

Insofar as the recognition of deferred-tax assets is concerned, they were valued in accordance with
realistic assumptions that they would be realized and the tax benefits would be recovered within the
limited time horizon covered by the industrial plans approved by the Company. Accordingly, only a portion
of the amount of the theoretical prepaid taxes computed on the reserves for risks was used for valuation
purposes.



15. Provisions for Risks and Charges
The provisions for risks and charges, which were established to cover contingent liabilities, increased
to 689,389,0000 euros, or 12,137,000 euros more than at December 31, 2008, as a result of the
changes listed in the table that follows:

(in thousands of euros) 12/31/2008 Additions Utilizations Other changes 12/31/2009
and reclassif.
- Disputed tax items 54,364 2,137 (779) - 55,722

- Other risks and charges 90,919 12,861 (36,746) - 67,034
Total provisions for risks and charges 677,252 66,072 (53,695) (240) 689,389

More specifically:
• The main components of additions concern financial expense on decommissioning provisions
(12,746,000 euros), and additions to provisions for environmental, legal and tax related risks
(22,055,000 euros).
• Utilizations reflect primarily disbursements to settle a dispute with UBS concerning the savings
shareholders (29,000,000 euros) and to purchase green certificates (6,797,000 euros) and CO2
emissions rights (2,720,000 euros).

More detailed information about the entries that resulted in the current composition of the provisions
for risks and charges is provided in the section of the Notes to the Consolidated Financial Statements
entitled “Status of the Main Legal and Tax Disputes Pending at December 31, 2009.”

16. Bonds
The balance of 1,198,771,000 euros represents the non-current portion of the bonds issued, valued at
amortized cost.
The table below shows the balance outstanding at December 31, 2009 and indicates the fair value of
each bond issue:

Total Edison Spa 1,900,000 1,198,771 720,626 1,948,147

In July 2009, within the framework of a Euro Medium-term Loan Program of up to 2 billion euros, the
Company issued 700 million euros in five-year bonds, sold exclusively to qualified investors. The bonds,
which are traded on the Luxembourg Securities Exchange, have a minimum denomination of 50,000
euros, mature on July 22, 2014, carry a coupon of 4.25% and were offered at a 99.841 issue price.
The effective gross yield to maturity is 4.286%, which represents a yield 145 basis points higher than
the reference rate (five-year mid-swap rate).



17. Long-term Borrowings and Other Financial Liabilities
A breakdown of these liabilities is as follows:

Due to banks 1,446,654 273,114 1,173,540
Due to other lenders 29,311 1,087 28,224
Total at 12/31/2009 1,475,965 274,201 1,201,764

The increase compared with December 31, 2008 is due mainly to:
• The utilization of committed credit lines to provide the Edison International Spa subsidiary with the
resources needed to cover a payment of 1,011 million euros for the acquisition of the Abu Qir
concession, in Egypt;
• In May 2009, the signing of a three-year loan agreement for a 600-million-euro facility provided by
a pool of international banks. This facility, which is repayable in a lump sum in May 2012, accrues
interest at an interest rate indexed to the Euribor plus a spread consistent with the best market
terms currently available.

The amount due to other lenders includes the long-term portion of the liability under the lease for the
new Leonis ship (28,442,000 euros), which was commissioned in the fourth quarter of 2009.

18. Other Liabilities
The balance of 22,343,000 euros reflects the suspension of the gain earned by Edison Spa on the sale
of a 51% interest in Dolomiti Edison Energy in 2008, while agreements providing both parties with put
and call options are in effect.

19. Current Liabilities
A breakdown of current liabilities, which amounted to 2,470,879,000 euros, is provided below:

Bonds 720,626 9,000 711,626
Short-term financial debt 702,632 1,017,969 (315,337)
Trade payables 758,937 1,224,607 (465,670)

Other liabilities 270,949 543,774 (272,825)
Total current liabilities 2,470,879 2,811,457 (340,578)

The main current liability accounts are reviewed below:
• Bonds include the full amount of a bond issue maturing on December 10, 2010 (701,549,000
euros) and the value of accrued interest at December 31, 2009, which also reflects the effects of
the valuation of this item at amortized cost.

• Short-term financial debt includes 472,711,000 euros owed to subsidiaries and affiliated
companies; 199,082,000 euros in liabilities toward factors; 27,349,000 euros due to banks;
1,195,000 euros arising from the measurement at fair value of interest rates and currency
derivatives; and 2,295,000 euros for the short-term portion of the liabilities under finance leases.

Hydrocarbons operations 436,671 752,059 (315,388)
Corporate activities 21,950 22,446 (496)
Total trade payables 758,937 1,224,607 (465,670)

Trade payables reflect mainly purchases of electric power, natural gas and other utilities, as well as
services related to plant maintenance.
The decrease in trade payables is due for the most part to a reduction in the quantities of natural gas
purchased as a result of lower in demand in the market served by the Company.
• Current taxes payable reflect the liability for the 6.5% corporate income tax (IRES) surcharge
introduced by Decree Law No. 112 of June 25, 2008 (the so-called “Robin Hood Tax”), as amended
by Law No. 99 of July 23, 2009, amounting to 11,309,000 euros. The balance of 6,426,000 euros
represents the liability for the regional tax (IRAP), net of estimated payments made.

Net Financial Debt
At December 31, 2009, net financial debt totaled 1,188,118,000 euros, or 345,418,000 euros less
than the 1,533,536,000 euros owed at December 31, 2008. This improvement is mainly the net result
of the following items:

Decreases:
• 1.138 million euros from the operating cash flow from continuing operations;
• 323 million euros from the collection of dividends from subsidiaries;

Increases:
• 268 million euros for dividend payments;
• 217 million euros for additions to property, plant and equipment;
• 172 million euros for new equity investments, including the contributions provided in 2009 to cover
losses;
• 120 million euros for tax payments;
• 49 million euros for borrowing costs.

Consistent with the practice followed at the end of 2008, the table below provides a simplified breakdown

NOTES TO THE INCOME STATEMENT
The net profit earned by Edison Spa in 2009 grew to 423 million euros, or 49 million euros more than
the 374 million euros reported at December 31, 2008.

EBITDA totaled 647 million euros. The decrease of 30 million euros (-4,4%), compared with the 676
million euros earned in 2008, is the net result of the following factors:

• A decrease of 147 million euros (-41,2%) reported by the hydrocarbon operations, due mainly
due a reduction in unit sales caused by sharply lower prices of benchmark oil commodities and by
a contraction in national demand for natural gas, offset only in part by a reduction in the average
price paid for natural gas;
• an increase of 126 million euros (+30,2%) reported by the electric power operations resulting
from the lower costs paid for natural gas and a greater utilization of the hydroelectric power plants.

In the case of the hydrocarbons operations, EBITDA were reduced by charges for foreign exchange
and commodity hedges amounting to 134 million euros, compared with 2008.

The difference in reported net profit compared with the previous year reflects the combined effect of
the following factors:
• A decrease of 61 million euros in depreciation and amortization caused by the change in scope of
operations that resulted from the divestment of some hydroelectric power plants in 2008.
• A decrease of 16 million euros in net financial expense made possible mainly by a reduction in the
average borrowing rate.
• A rise of 33 million euros in currency translation losses, referred both to commercial transactions
and to transactions hedging fluctuations in the U.S. dollar exchange rate.
• A decrease of 41 million euros in net income from equity investments. Specifically, the positive
effect on the year-over-year comparison of an increase of 52 million euros in dividends reported in
2009 was more than offset by the 92 million euro gains on the sale of equity investments
recognized in 2008.
• A decrease of 59 million euros in income tax expense, despite an increase of one percentage point in
the corporate income tax surcharge (the Robin Hood Tax). This decrease is due mainly to the fact that
in 2008, following the introduction of the Robin Hood Tax (5.5% in 2008), the deferred-tax amounts
recognized at that time were adjusted accordingly, with a negative effect of 53 million euros.



21. Sales Revenues
A breakdown by type of the Company’s sales revenues, which were booked mainly in Italy, is provided
below:

Total 5,007,395 5,927,329 (919,934) (15.5%)

In April 2009, following the outcome of an action filed before the Regional Administrative Court
challenging Resolution No. 154/08, which defined the avoided-fuel-cost rate component, the AEEG
issued on a provisional basis Resolution No. 50/09, which determines the estimated rates that should
be charged in monthly billing to the Electrical Services Manager. Absent explicit statutory guidance, the
Company estimated the avoided-fuel-cost rate component for 2008 and 2009 taking into account the
findings of illegality set forth in the Regional Administrative Court’s decision.

The revenue shortfall that occurred in both business segments is analyzed below:

• The main reason for the 26.1% decrease in sales revenues reported by the electric power
operations is a drop in unit sales, caused both by a reduction in demand for electric power and by
the divestment of some thermoelectric and hydroelectric power plants in 2008.
Electric power revenues also reflect the positive impact of Resolution No. 77/08 (84 million euros),
which defined the criteria for the reimbursement of costs incurred by companies with CIP 6/92
power plants to comply with emissions rights requirements.
• In the case of the hydrocarbons operations, the 2.6% decrease in revenues is due to a reduction
in unit sales caused by lower demand for natural gas.
Revenues from services provided refer mainly to the coordination support provided by Edison to the
other Group companies and to engineering services.

Out of period income reflects the portion attributable to previous years (17,036,000 euros) of the
positive impact produced by AEEG Resolutions No. 30/09 and No. 80/08, which provided for the
reimbursement of costs incurred to purchase green certificates; the derecognition of costs accrued in
previous years (11,374,000 euros); the proceeds generated from the redefinition of contractual stipulations
with a partner (10,000,000 euros); and positive differences on provisions recognized in connection with
Resolution No. 248/06 (2,991,000 euros). In 2008, out of period income included the positive effect
of AEEG Resolutions No. 77/08 and No. 80/08 concerning CO2 emissions certificates and green
certificates.

Insurance settlements refer mainly to accidents that occurred in previous years at two thermoelectric
power plants.

Utilizations of provisions for risks include 2,382,000 euros for the reversal in earnings of provisions
established in connection with the sale of some industrial properties.

Total 4,462,674 5,511,465 (1,048,791) (19.0%)

The decrease in costs for CO2 emissions rights reflects both the drop in the level of emissions
generated that resulted from a decrease in production volumes and a reduction in the unit cost paid to
purchase the certificates.

The sharp increase shown for commodity derivatives is consistent with the price and foreign exchange
trends for the hedged commodities, as discussed in the Risk Management section of this Report.

Additions to provisions for risks refer mainly to costs that the Company expects to incur in future
years for environmental remediation projects at some decommissioned industrial sites.

The main components of sundry charges are out of period charges (10,208,000 euros), advertising
expenses (7,088,000 euros) incurred mainly for corporate communications, corporate expenses (6,474,000
euros), losses on disposals of property, plant and equipment (7,680,000 euros) and indirect taxes and
fees (5,708,000 euros).

Breakdown of Raw Materials and Services Used by Type of Business
Electric power operations 583,233 1,047,112 (463,879) (44.3%)

24. Labor Costs
Labor costs totaled 136,557,000 euros, or 2,422,000 euros less than in 2008 (138,979,000 euros).

At December 31, 2009, the Company had 1,735 employees, 38 more than at the end of 2008. The
table below provides a breakdown by category of the Company’s staff:

(Employee category) 01/01/2009 Added to Removed Change of 12/31/2009 Average

25. EBITDA

(in thousands of euros) 2009 as a % of sales 2008 as a % of sales 2008-2009
EBITDA revenues EBITDA revenues % change
Electric power operations 540,693 22.4% 415,123 12.7% 30.2%
Hydrocarbons operations 208,922 8.1% 355,535 13.5% (41.2%)
Corporate activities (103,103) n.m. (94,634) n.m. 8.9%
Total 646,512 12.9% 676,024 11.4% (4.4%)

The decrease in EBITDA is basically the net result of the following contrasting factors:
Negative factors:
• Lower unit sales both by the electric power operations and by the hydrocarbons operations;
• Charges related to financial derivatives hedging foreign exchange and commodity price fluctuations
(134,042,000 euros);
• The change in scope of operations that resulted from the conveyance of assets to Co Energy Power,
Dolomiti Edison Energy and Hydros in 2009.

Positive factors:
• An increase of the operating margins of the electric power operations resulting from the lower
prices paid for the main components of the cost of production and a greater utilization of the
hydroelectric power plants;
• The positive impact produced by AEEG Resolutions No. 30/09 and No. 80/08 (17,036,000 euros),
which provided for the reimbursement of costs incurred in previous years to purchase green
certificates;
• The positive impact of Resolution No. 77/08 (84,100,000 euros), which defined the criteria for the
reimbursement of costs incurred by companies with CIP 6/92 power plants to comply with
emissions rights requirements.



26. Depreciation, Amortization and Writedowns
A breakdown of this item is as follows:

Depreciation of property, plant and equipment 323,289 376,496 (53,207) (14,1%)
Depreciation of investment property 120 96 24 25,0%
Amortization of hydrocarbon concessions 18,804 21,577 (2,773) (12,9%)
Amortization of other intangible assets 11,027 15,962 (4,935) (30,9%)

Writedown of property, plant and equipment 15,069 45,890 (30,821) n.m.
Writedown of other intangible assets 18 - 18 n.m.
Reversal of writedown of prop., plant and equip. - (14,581) 14,581 n.m.
Total for Edison Spa 368,327 445,440 (77,113) (17,3%)

Breakdown by Business Segment
An analysis of the main changes that occurred compared with 2008 is provided below:

Electric power operations 290,430 351,505 (61,075) (17.4%)
Hydrocarbons operations 68,301 84,231 (15,930) (18.9%)
Corporate activities 9,596 9,704 (108) (1.1%)
Total for Edison Spa 368,327 445,440 (77,113) (17.3%)

• The decrease shown for the electric power operations is due to the adjustment of the residual
value of some thermoelectric and hydroelectric power plant in addition to the following factors:
- The conveyance, in 2008, to Dolomiti Edison Energy and Hydros Srl of 10 hydroelectric power
plants in the provinces of Trent and Bolzano (22,288,000 euros);
- End of depreciation of equipment replaced at a thermoelectric power plant (14,504,000 euros);
- Expiration of the CIP 6/92 contract for a thermoelectric power plant (12,108,000 euros).

Amortization of other intangible assets refers to patents, trademarks and similar rights (8,115,000
euros) and hydrocarbon exploration costs (2,912,000 euros).

The net writedowns, for 15,087,000 euros are substantially due to impairment test; additional
information about the impairment test is provided in the section of these Notes entitled “Impairment
Test Applied to the Value of Goodwill, Property, Plant and Equipment and Other Intangibles”.



27. Net Financial Income (Expense)
Net financial expense amounted to 49,166,000 euros, for a net increase of 16,599,000 euros compared
with 2008. This increase reflects the combined effect of these two contrasting factors:
• A negative change of 33,058,000 euros in the result from foreign exchange transactions related
both to commercial transactions and derivative transactions executed to hedge the risk of
fluctuations in foreign exchange rates;
• A reduction of 16,459,000 euros in net financial expense due mainly to the effect of lower interest
rates in 2009.

A breakdown of the components of financial income and expense is as follows:

(in thousands of euros) 2009 2008 Change

More specifically:
• Information about other transactions involving financial derivatives is provided in a separate
disclosure elsewhere in this Report;
• Interest paid to other lenders includes the charges incurred for transactions to factor receivables
without recourse;
• Other financial expense includes 1.425.000 euros in accrued interest on employee severance
indemnities, computed in accordance with IAS 19 (1.658.000 at December 31, 2008);
• Commercial transactions generated foreign exchange translation losses of 6,796,000 euros.

Foreign exchange translation gains and losses also included derivative transactions executed to
hedge foreign exchange risks on purchases of commodities. These transactions generated a net loss
of 8,879,000 euros in 2009.

29. Other Income (Expense), Net
Net other expense of 9,286,000 euros is the result of nonrecurring items that are not related directly
to the core businesses operations. The main items included in this account are:
• Income of 16,529,000 euros, of which 8,000,000 euros from settlements with several insurance
companies of claims and 4,000,000 euros in compensation for breech of contractual guarantees in
connection with the acquisition of EDF Energia Italia;
• Expense of 25,815,000 euros, the main components of which are 12,647,000 euros in expenses
related to litigation and tax disputes, 8,303,000 euros for adjustments to some provisions for risks.

30. Income Taxes
A breakdown of income taxes and a comparison with the data for 2008 is provided below:

Current taxes 166,392 113,776 52,616
Net deferred-tax liabilities (assets) (57,824) 53,395 (111,219)
Income taxes attributable to previous years (2,333) (2,010) (323)
Total 106,235 165,161 (58,926)

The total tax liability at December 31, 2009 reflects the impact of an increase of one percentage
point in the corporate income tax surcharge (the so-called Robin Hood Tax) introduced by Law No.
99 of July 23, 2009, which had a negative impact of 11,760,000 euros, including 7,495,000 euros
in deferred-tax liabilities. At December 31, 2008, the restatements of deferred-tax assets and liabilities
required by the introduction of the Robin Hood Tax resulted in a charge of 52,568,000 euros.

Current taxes include 144,000,000 euros for corporate income taxes (4,235,000 euros attributable
to the surcharge increase), 23,800,000 euros for regional taxes and a benefit of about 1,241,000 euros
generated by filing a consolidated income tax return.

The effective tax rate for the period was 19%. The difference compared with the nominal tax rate of
37.9% is the net result of the positive effect of the participation exemption on dividends, partially offset
by the abovementioned increase of the “Robin Hood Tax”.



The table that follows provides a breakdown of deferred-tax liabilities and assets and shows the
changes that occurred in the first half of 2009:

(in thousands of euros) 12/31/2008 Additions Utilizations Restatement for new rates 12/31/2009

31. Profit (Loss) from Discontinued Operations
This account had a zero balance at December 31, 2009, as against a net profit of 9,927,000 euros a year
earlier, generated by the sale of the business operations consisting of five thermoelectric power plants
operating under CIP 6/92 contracts and of Termica Boffalora and Termica Celano (the “Disposal Group”).

Guarantees Provided
The balance of 1,402,842,000 euros, which is determined based on the undiscounted amount of the
contingent commitment on the balance sheet date, is virtually the same as at the end of 2008.
Guarantees provided included the following:
• 402,211,000 euros in guarantees provided by Edison Spa to the Milan tax office on behalf of
subsidiaries for offsetting VAT credits and those provided to subsidiaries in connection with the
intra-Group assignment of tax credits.
• 50,000,000 euros pursuant to the Tolling and Power Purchasing Agreements, according to which
Edison is responsible for the commercial obligations undertaken by its Edison Trading Spa
subsidiary toward Edipower.
• Guaranteed provided by the Group’s Parent Company on its own behalf and on behalf of
subsidiaries and affiliated companies to secure the performance of contractual obligations account
for the balance.

Collateral Provided
Collateral provided, which totaled 1,159,514,000 euros, or 4,761,000 euros less than at December 31,
2008, represents the value of the assets or rights provided as collateral on the balance sheet date. This
item includes collateral provided for liabilities carried on the balance sheet, such as a pledge on Edipower
shares (1,066 million euros) provided to a pool of banks to secure a loan. Encumbrances provided to
secure other loans (62,804,000 euros) account for the remaining balance.

Other Commitments and Risks
This item, which totaled 638 million euros, reflects primarily commitments undertaken to complete
investment projects under construction.

In particular:

• the following contracts were signed for 97 million euros to address the deficit in CO2 emission
quotas:
- Emission Reductions Purchase Agreements (ERPAs) for the purchase of Certified Emission
Reduction certificates (CERs) in China within 2012.
- A Management Agreement with EDF Trading (EDF Carbon Fund) involving the purchase for a
fixed price of Certified Emission Reduction/Emission Reduction Units within 2013.
- An agreement with Natsource to join the Natsource Carbon Asset Pool, a fund established to
purchase CO2 emissions reduction credits generated by Clean Development Mechanism/Joint
Implementation projects within 2013
• The company have entered into the contracts for the importation of natural gas, which contain the
take-or-pay clauses that obligate the buyer to pay for any shortage between the stipulated maximum
quantities and the quantity actually used (unless the shortage is due to causes not provided for in the
contract), with the option for the buyer to make up, at certain conditions, the paid but unused volume
over the life of the contract. In particular at the end of year, a balance of 29 million euros is included



in advances to suppliers and 53 million euros not yet paid are recognized as a commitment. Gas
delivery profiles and the economic recoverability are periodically updated during the year.

Unrecognized Commitments and Risks
Significant commitments and risks not included in the amounts listed above are reviewed below:

1) The hydrocarbons operations have entered into long term contracts for the importation of natural
gas with Russia, Libya, Norway, Algeria and Qatar (which supply contract went into effect in 2009),
that provide total supplies, at full capacity, of 15.8 billion cubic meters of natural gas a year. The
duration of these contracts ranges between 2 and 25 years.
Concerning the gas natural import for next years, a contract to import natural gas from Algeria
(Protocolle d’accord) has been signed with Sonatrach in November 2006 that calls for the supply
of 2 billion cubic meters of natural gas a year through the new pipeline linking Algeria with Sardinia
and Tuscany that will be built by Galsi. The implementation of this agreement is subject to the
construction of the pipeline, which is currently in the project development phase.
The contract concerning Terminale GNL Adriatico Srl went into effect in the second half of 2009
and for which Edison, while owning just 10% of the infrastructure, will have access to about 80%
of the terminal’s gasification capacity, includes the following conditions:
• For all shareholders, the obligation not to transfer their equity interest until 36 months have
passed from the startup of the terminal, but, in any case, not later than July 1, 2011 (lockup
clause).
• For the two majority shareholders, the right to buy the 10% interest held by Edison if the supply
contract with RasGas should be cancelled for reasons for which Edison is responsible (call
option). The price for the sale of shares, if the call option is exercised, will be determined based
on the sum of the capital contributions provided until the options are exercised.

2) In the electric power operations:
• Edison granted to Cartiere Burgo Spa a “call option” to purchase a 51% interest in Gever. This
option is exercisable when the contract under which Gever supplies Cartiere Burgo with electric
power and steam expires (in 2017) at a price equal to the corresponding pro rata interest in the
company’s shareholders’ equity.
• Edison granted to Petrobras an option to buy its interest in Ibiritermo, exercisable in 2022 when
the lease expires.
• Agreements executed in connection with the sale of a 51% interest in Dolomiti Edison Energy Srl
provide Edison with a call option, which may be exercised only if the hydroelectric concessions
have not been extended by March 31, 2018.
• Edison Spa and Akarport Sa extended to June 30, 2010 the Preliminary Agreement that sets forth
the obligations of both parties with regard to the handling of coal and coal-based products at a
new power plant in Greece. Under the terms of the Preliminary Agreement, if Edison cancels the
agreement before June 30, 2010 after obtaining the Power Generation License and the
Installation License, Edison will be required to pay Akarport compensation in the amount of 50,000
euros. If by June 30, 2010 Edison communicates in a Confirmation Letter its unchallengeable
decision to build the facility and subsequently decides to abandon the project, the Agreement will
be cancelled and Edison will incur penalties of up to 20 million euros.

As part of the agreements among the shareholders of RCS Mediagroup who are members of the
Blocking and Consultation Syndicate, any Participant who, in response to a tender offer, wishes to exit
the Syndicate will be required to sell the syndicated shares to the other Participants. The buyers will
have the right, but not the obligation, to buy the shares that are being offered in proportion to the
percentage of the shares they contributed to the Syndicate.

Tax Status
B: Reserves the taxation of which has been suspended and which, if utilized, would be included in the
Company’s taxable income.
C: Reserves the taxation of which has been suspended that are part of share capital. If the share
capital is reduced upon a shareholder distribution, these reserves would become taxable.
D: Portion of shareholders’ equity restricted pursuant to Section 469 of Law No. 266/2005 (so-called
realignment), which, if utilized, would be included in the Company’s taxable income, increased by a 12%
substitute tax, with the concurrent earning of a 12% tax credit (equal to the substitute tax paid).
E: Reserves that, if distributed, would not be included in the taxable income of the shareholders.

Utilization Options
1: Capital increase.
2: Replenishment of losses.
3: Distribution to shareholders.

A breakdown according to tax status is provided below:

• The reserves for government grants, with B status, include the following:
- former Edison - grants under Article 55 3,770
- former Edison Gas - Law No. 488/92 15,055



• The reserves the taxation of which has been suspended that are part of share capital, with C status,
include the following
- No. 576 of 12/1/75 (old Edison form. Montedison) 31,064
- No. 72 of 3/19/83 (old Edison form. Montedison) 15,283
- No. 576 of 12/1/75 (former Finagro) 1,331
- No. 72 of 3/19/83 (former Montedison) 8,561
- No. 72 of 3/19/83 (former Silos di Genova Spa) 186
- No. 576 of 12/1/75 (former Calcemento) 976
- No. 72 of 3/19/83 (former Calcemento) 4,722
- 413 of 12/30/91 (former Sondel) 2,976
- No. 413 of 12/30/91 (former Edison) 118,911

Any taxes that may be due (counting also the 6.5% corporate income tax surcharge) on the reserves
listed above would amount to 7.1 million euros for those of Item B, 65.3 million euros for those of Item
C and 170 million euros (net of tax credit) for those of Item D.

As for the negative income components that are not reflected in the income statement, which until
2008 could be deducted by listing them on a separate schedule annexed to the income tax return, the
provision of the tax code require that a corresponding amount of the unrestricted reserves and retained
earnings should be maintained on the Company’s financial statements and, if the abovementioned
amount is distributed, it would be included in the Company’s taxable income.

As a result of non-accounting depreciation and amortization taken in 2006 and 2007 and the derecognition
in 2004 of entries booked for tax purposes but which had no relevance for statutory reporting purposes,
non-accounting deductions still available totaled about 223 million euros. Deferred taxes totaling about
76 million euros were recognized in connection with these entries.

Therefore, should the Company choose to distribute earnings or reserves, it must have residual qualified
reserves, as defined in Article 109 of the Uniform Tax Code, totaling 147 million euros. If the Company
lacks or has insufficient qualified reserves, any uncovered portion of the distribution, increased by the
applicable deferred taxes, would become part of the Company’s taxable income.

Lastly, the reform of the corporate income tax system, which went into effect on January 1, 2004,
introduced the overriding presumption that the profit for the year and the portion of reserves other than
share capital reserves that has not been set aside in a suspended taxation status will be distributed,
irrespective of the motions approved by the Shareholder’s Meeting (Article 47 of the Uniform Tax Code).

A) Intercompany Transactions
Transactions between Edison Spa and its subsidiaries and affiliated companies and its controlling
company consist primarily of:
• Commercial transactions involving the buying and selling of electric power and natural gas, green
certificates and CO2 emissions rights.
• Transactions involving the provision of services (technical, organizational and general) by
headquarters staff.
• Financial transactions involving lending and current account facilities established within the
framework of the Group’s centralized cash management system.
• Transactions required to file a consolidated VAT return for the Group (so-called VAT Pool).

With the exception of transactions related to the VAT Pool and the consolidated corporate income tax
return, which are executed pursuant to law, all of the transactions listed above are governed by contracts
with conditions that are consistent with market terms, i.e., the terms that would be applied by two
independent parties.
In the area of commercial transactions, the Group’s Parent Company, Edison Spa, sells natural gas and
electric power to Edison Trading Spa and Edison Energia Spa, respectively, under special contracts that,
taking into account the specific functions of the two buyer companies within the Group, provide the
seller with adequate coverage of its fixed and variable costs. In addition, the rate earned on transactions
involving intra-Group current accounts is the Deposit Rate, while the rate paid is the Marginal Refinance
Rate, both of which are determined by the European Central Bank.

Consolidated VAT Return - Edison Spa files a consolidated VAT return (so-called VAT Pool) that
includes those companies of the Edison Group that meet the requirements of Article 73, Section 3, of
Presidential Decree No. 633/72, as amended, and of the Ministerial Decree dated December 13, 1979.
Under the consolidated return system, Group companies transfer to Edison Spa, either monthly or
quarterly, VAT payable and receivable positions in order to allow Edison Spa to offset these positions
and pay only the resulting debit balance, if any. The Group VAT return for December 2009 shows that
the Group had a net credit toward the tax administration of about 16,428,000 euros.

Consolidated Corporate Income Tax (IRES) Return - In June 2009, Transalpina di Energia Srl, the
Group’s controlling company, renewed the option of filing a consolidated income tax return for three
years from 2009 to 2011. Bilateral agreements, with the same provisions for all companies, governing
the relationships arising between the controlling company and the companies included in the consolidated
tax return were executed on the same occasion.
Group companies that engage in the exploration for and production of hydrocarbons and in the production
and distribution of electric power are subject to the 6.5% corporate income tax (IRES) surcharge and
are required to pay this surcharge directly, even if they are included in the consolidated IRES return. In
2009, the IRES surcharge was raised from 5.5% to 6.5%, pursuant to a provision of Law No. 99 of
July, 23 2009.

B. Transactions with Other Related Parties
In 2009, Edison Spa engaged in a number of commercial and financial transactions with some of its
current shareholders and/or companies controlled by them. An overview of these transactions, which
were carried out in the normal course of business based on contractual terms mutually agreed upon
by the parties and consistent with regular market practices, is provided below.

1. Commercial Transactions
As shown in the summary schedule, these transactions refer mainly to revenues generated by sales of
natural gas, electric power and transmission services and the rebilling of maintenance costs.



2. Financial Transactions
The main financial transactions executed by Edison Spa in which its shareholder banks played a significant
role are reviewed below:
• Banca Popolare di Milano provided Edison with an 70-million-euro revocable line of credit that
accrues interest at market rates. At December 31, 2009, 37.4 million euros in sureties had been
drawn against this credit line, which, however, had not been used for short-term borrowings and
current account overdrafts.
• In 2004, Mediobanca provided Edison Spa with 120 million euros in financing against EIB funds,
which has been partially repaid in accordance with the amortization plan. At December 31, 2009,
the outstanding balance was about 104 million euros.

3. Other Transactions
In May 2009, further to the acquisition in 2006 of the entire share capital of EDF Energia Italia (later
merged by absorption into Edison Energia) from EDF International and, in subsequent years, the filing
by Edison of compensation claims for breaches of the contractual guarantees provided by the seller,
the parties reached a settlement pursuant to which EDF International paid Edison 4 million euros.

Significant Nonrecurring Events and Transactions
The following significant nonrecurring transactions were executed in 2009:
• Financing facility in the amount of 1,011 million euros provided to the Edison International Spa
subsidiary to fund the acquisition of the Abu Qir hydrocarbon concession, north of Alexandria, In Egypt.
• Purchase for 25 million euros of an 80% interest in AMG Gas Srl, a company that distributes
natural gas to customers in the Palermo area.
• Acquisition of control of Sistemi di Energia.

Transactions Resulting from Atypical and/or Unusual Activities
As required by CONSOB Communication No. DEM/6064293 of July 28, 2006, Edison Spa declares
that in 2009 it did not execute atypical and/or unusual transactions, as defined in the abovementioned
Communication.

Treasury Shares
At December 31, 2009, the Company did not own any treasury shares.
