NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM

FINANCIAL STATEMENTS

(in millions of Argentine Pesos (“$”) – unless otherwise stated)

NOTE 2:(Continuation)

Power capacity availability is determined independently of the reservoir level, the contributions made, or the expenses incurred. Furthermore, in the case of pumping hydroelectric power plants, the following is considered to calculate availability: i) the operation as turbine at all hours within the period, and ii) the availability as pump at off-peak hours every day and on non-business days.

The base remuneration is determined by the actual power capacity plus that under programmed and/or agreed maintenance:

Technology/Scale	Base Price (U$S/MW- month)
Medium HI Capacity > 120 ≤ 300 MW	3,000
Small HI Capacity > 50 ≤ 120 MW	4,500
Large Pumped HI Capacity > 120 ≤ 300 MW	2,000

Similarly to the provisions of Resolution No. 22/16, in the case of hydroelectric power plants maintaining control structures on river courses and not having an associated power plant, a 1.20 factor will be applied to the plant at the headwaters.

The additional remuneration applies to power plants of any scale for their actual availability and based on the applicable period:

Type of Power Plant	Period	Additional Price (U$S/MW- month)
Conventional	May 17 – Oct. 17	500
Conventional	Nov. 17 onwards	1,000
Pumped	May 17 – Oct. 17	-
Pumped	Nov. 17 onwards	500

As from November 2017, the allocation and collection of 50% of the additional remuneration will be conditional upon the generator: i) taking out insurance, to CAMMESA’s satisfaction, to cover for major incidents on critical equipment; and ii) the progressive updating of the plant's control systems pursuant to an investment plan to be submitted based on criteria to be defined by the SEE.

Other Technologies

The remuneration is made up of a base price and an additional price associated with the availability of the installed equipment with an operating permanence longer than 12 months as from the beginning of the Summer Seasonal Programming.

2.1.1.3 Additional Remuneration for Efficiency

The Resolution keeps in force the additional remuneration for efficiency created by Resolution No. 482/15.

2.1.1.4 Additional Remuneration for Low-Use Thermal Generators

The Resolution provides for an additional remuneration for low-use thermal generators having frequent startups based on the monthly generated energy for a price of U$S 2.6/MWh multiplied by the usage/startup factor.

The usage factor is based on the Rated Power Use Factor recorded during the last rolling year, which will have a 0.5 value for thermal units with a usage factor lower than 30% and a 1.0 value for units with a usage factor lower than 15%. In all other cases, the factor will equal 0.0.

The startup factor is established based on startups recorded during the last rolling year for issues associated with the economic dispatch made by CAMMESA. It will have a 0.0 value for units with up to 74 startups, a 0.1 value for units recording between 75 and 149 startups, and a 0.2 value for units recording more than 150 startups. In all other cases, the factor will equal 0.

2.1.1.5 Repayment of Overhaul Financing (applicable to thermal and hydroelectric generators)

The Resolution abrogates the Maintenance Remuneration and provides that, as regards the repayment of outstanding loans applicable to thermal and hydroelectric generators, credits already accrued and/or committed to the cancellation of such maintenance works will be applied first. The balance will be repaid by discounting U$S 1/MWh for the energy generated until the total cancellation of the financing.

2.1.2. Recategorization of hydroelectric power plants of subsidiary HINISA:

On April 10, 2017, the SEE provided for the recategorization of the Nihuil I, Nihuil II and Nihuil III plants as small-scale plants for the application of the effective remuneration scheme. Thus, the SEE rectified the incorrect categorization initially assigned to these plants in line with the repeated claims lodged by the Company since April 25, 2013.

Pursuant to the terms of the SEE's instruction to CAMMESA, the recategorization is effective as from April 2017.

The impact of this recategorization represents a 50% increase in the base remuneration for power capacity, which thus rises from U$S 3,000 - month to U$S 4,500 -month.

2.1.3. Signature of the WEM Supply Agreement SE Resolution No. 2207/07

On July 14, 2017, CTLL entered into with CAMMESA the WEM Supply Agreement under SE Resolution No. 220/07 for the new 105 MW high-efficiency gas turbine, retroactively as of July 15, 2016, date on which it was commissioned for service, committing a 79.35 MW, which represents 75.6%, of the turbine's power capacity. The remaining 24.4% capacity will continue to be compensated under SEE Resolution No. 19/2017.

The economic impact of the new remuneration for CTLL amounted to $ 378 million,which is recognized in the Statement of Comprehensive Income under Revenues from sales as of September 30, 2017.

2.1.4. Resolution No. 281/17 - MAT Renewable Electric Power Regime

2.1.5.3 Co-generation and Closing of Combined Cycles

Pursuant to SEE Resolution No. 420/2017, SEE Resolution No. 287/17 was published, which opened a call for bids to all parties interested in developing projects for co-generation and the closing of combined cycles over existing equipment, without limit to the power capacity to be installed. The projects should have low specific consumption (lower than 1,680 kcal/kWh with natural gas and 1,820 kcal/kWh with alternative liquid fuels).

It is a condition that the new capacity should not exceed the existing electric power transmission capacity; otherwise, the cost of the necessary extensions will be assumed by the Bidder.

Awarded projects will be remunerated under a Wholesale Demand Agreement and will have a payment priority equivalent to the recognition of fuel costs by the WEM for a term of 15 years. The remuneration will be made up of the available power capacity price, plus variable non-fuel cost for the delivered power, plus fuel cost (if offered), less penalties and fuel surpluses. Power capacity surpluses are remunerated pursuant to SEE Resolution No. 19-E/17. Thedemand contracts payment priority will be the same than that applicable to the coverage of fuel generation costs.

Within this framework, 19 projects for the closing of combined cycles for a total capacity of 1,884 MW and 21 co-generation projects for a total capacity of 2,713 MW were filed.

The Company and its subsidiaries have submitted offers for the execution of three projects: i) a co-generation project at the Puerto General San Martín plant; ii) the closing of CTLL’s combined cycle; and iii) the closing of Genelba Plus’ combined cycle.

Through Resolution No. 820-E/17, the SEE awarded only three co-generation projects (not including the one filed by the Company) for a power capacity of 506 MW, and called the remaining offerors with qualifying offers to improve their offers.

Through Resolution No. 926-E/17, the SEE awarded the projects to be executed following the request to improve offers for a total capacity of 1,304 MW set forth in SEE Resolution No. 820-E/17.

Genelba Plus’ closing to combined cycle, which will add an incremental capacity of 383 MW to the Genelba power plant’s current facilities, is among the nine selected projects.

The project consists of the installation of a new gas turbine and a steam turbine, as well as other enhancement works over the current Genelba Plus gas turbine, which altogether will complete the second combined cycle at Genelba, with a total gross power of 552 MW. The Project’s investment budget is estimated to be approximately U$S 360 million, and the consortium of Siemens and Techint will be responsible for the supply of the equipment, as well as for the construction and commissioning of the Project on a turnkey basis. Its commissioning at open cycle is expected for the second quarter of 2019, and as closed cycle for the second quarter of 2020.

With this expansion, Genelba, which is located in Marcos Paz, Province of Buenos Aires, will have two combined cycles and reach an installed capacity of 1.2 GW. Currently, Genelba generates electric power with a 674 MW combined cycle and a 169 MW Genelba Plus gas turbine, where the Project will be conducted.

2.2 Distribution

2.2.1.Tariff Structure Review

On January 31, 2017, the ENRE issued Resolution No. 63/17, pursuant to which it determined the definitive Electricity Rate Schedules, the review of costs, the required quality levels, and all the other rights and obligations that are to be applied and complied with by Edenor as from February 1, 2017. The above-mentioned regulation was adapted by the ENRE by means of the issuance of Resolutions Nos. 81/17, 82/17, and 92/17, and Note No. 124,898.

The aforementioned resolution states that the ENRE, as instructed by the MEyM, shall limit the increase in the VAD resulting from the RTI process and applicable as from February 1, 2017, to a maximum of 42%, as compared to the VAD in effect at the date of issuance of the aforementioned resolution, with the remaining value of the new VAD being applied in two stages, the first of them in November 2017 and the last one in February 2018.

In addition to that which has been previously mentioned, the ENRE shall recognize and allow Edenor to bill the VAD difference arising as a consequence of the gradual application of the tariff increase recognized in the RTI in 48 installments as from February 1, 2018, which will be incorporated into the VAD’s value resulting as of that date.

Moreover, the aforementioned regulation sets forth the procedure for determining the mechanism for monitoring the variation of Edenor’s Own Distribution Costs (CPD), whose “trigger clause” will be applicable when the variation recorded in the six-month period being controlled exceeds 5%. In this regard, in August 2017, having the condition for the trigger clause to apply been met, Edenor requested that it be allowed to apply the variation recorded in the CPD in the first January–June 2017 six-month control period, which amounted to 11.63%.

Finally, ENRE Resolution No. 329/17 determines the procedure to be applied for the billing of the deferred income, setting that those amounts will be adjusted as of February 2018 applying for such purpose the Methodology for the Redetermination of the Company’s Recognized Own Distribution Costs, set forth in caption c2) of Sub-Appendix II to ENRE Resolution No. 63/17, and billed in 48 installments as from February 1, 2018.

As of September 30, 2017, the amount arising from such deferred income and not recognized by Edenor in these condensed interim financial statements amounts approximately to $ 4.2 billion.

2.2.2.Penalties

In addition to that which has been mentioned in Note 2.3 to the financial statements as of December 31, 2016, the following is worth pointing out:

2.2.2.1. ENRE Note No. 125,248 dated March 29, 2017

It sets the new penalty determination and adjustment mechanisms in relation to the control procedures, the service quality assessment methodologies, and the penalty system applicable as from February 1, 2017 for the 2017 – 2021 period set by ENRE Resolution No. 63/17, providing for the following:

i) Penalty values shall be determined on the basis of the kWh value, the average electricity rate, the cost of energy not supplied or other economic parameter at the value in effect at the first day of the control period or the value in effect at the date of the penalizable event for penalties arising from specific events.

ii) For all the events that occurred during the transition period (the period between the signing of the Adjustment Agreement and the effective date of the RTI) for which a penalty has not been imposed, penalties shall be adjusted by the consumer price index (IPC) used by the Argentine Central Bank (BCRA) to produce the multilateral real exchange rate index (ITCRM) for the month prior to the end of the control period or that for the month prior to the date of occurrence of the penalizable event for penalties arising from specific events, until the date on which the penalty is imposed. This mechanism is also applicable to the concepts penalized after April 15, 2016 (ENRE Note No. 120,151) and until the effective date of the RTI. This adjustment will be part of the penalty principal amount.

iii) Unpaid penalties will accrue interest at the Banco de la Nación Argentina lending rate for thirty-day discount transactions from the date of the resolution to the date of actual payment, as interest on late payment. In the case of penalties relating to Customer service, the calculated amount shall be increased by 50%.

iv) Penalties subsequent to February 1, 2017 will be valued at the kWh value or the cost of energy not supplied of the first day of the control period or of the day of occurrence of the penalizable event for penalties arising from specific events. Those concepts will not be adjusted by the IPC, applying the interest on late payment established in iii) above. Moreover, an additional fine equivalent to twice the amount of the penalty will be determined if payment is not made in due time and manner.

The impact of these new penalty determination and adjustment mechanisms has been quantified by Edenor and recognized as of September 30, 2017 (Note 22).

In accordance with the provisions of Sub-Appendix XVI to ENRE Resolution No. 63/17, Edenor is required to submit in a term of 60 calendar days the calculation of global indicators, interruptions for which force majeure had been alleged, the calculation of individual indicators, and will determine the related discounts, crediting the amounts thereof within 10 business days. In turn, the ENRE will examine the information submitted by Edenor, and in the event that the crediting of such discounts were not verified will impose a fine, payable to the Treasury, equivalent to twice the value that should have been recorded. At the date of these condensed interim financial statements, Edenor has submitted the aforementioned information relating to the six-month period ended August 31, 2017.

2.2.2.2 Penalty Adjustment

In different resolutions concerning penalties relating to the Quality of the Commercial and Technical Service, the Regulatory Entity has provided for the application of increases and adjustments, applying for such purpose a criterion different from the one applied by Edenor.

In this regard, Edenor does not know the formula used for obtaining such increase; therefore, it challenged the aforementioned resolutions requesting the suspension of their effects, which are not included within the amount of the provision for penalties recognized as of September 30, 2017.

2.2.3.Framework agreement

The approval of the extension of the Framework Agreement until September 30, 2017 was signed on August 3, 2017. The signing of the aforementioned agreement represents the recognition of revenue in favor of the Company relating to the distribution of electricity to low-income areas and shantytowns for the January 1, 2015 - September 30, 2017 period for an amount of $ 268.1 million.

In this regard, on October 23, 2017, the Company received a payment from the Federal Government for $ 122.6 million.

2.2.4Regulatory framework of Edenor – Law on electricity dependent patients

On May 17, 2017, Law No. 27,351 was passed, which guarantees the permanent and free of charge supply of electricity to those individuals who qualify as dependent on power for reasons of health and require medical equipment necessary to avoid risks in their lives or health. The law states that the account holder of the service or someone who lives with him/her (a cohabitant) that is registered as “Electricity dependent for reasons of health” will be exempt from the payment of any and all connection fees and will benefit from a special free of charge tariff treatment in the electric power supply service under national jurisdiction, which consists in the recognition of the entire amount of the power bill.

On July 26, 2017, the ENRE issued Resolution No. 292, stating that those discounts are to be made as from the effective date of the aforementioned law, and instructing CAMMESA to implement those discounts in its billing to distribution companies.The amounts paid by customers for the bills covered by this Resolution will be made available in the stipulated time limits.

According to Executive Order 740 of the PEN, dated September 20, 2017, the MEyEM will be the Authority of Application of Law No. 27,351, whereas the Ministry of Health will be responsible for determining the conditions necessary to be met for registration with the “Registry of Electricity Dependent for Reasons of Health” and will issue the clarifying and supplementary regulations for the application thereof.

On September 25, 2017, the National Ministry of Health issued Resolution No. 1538-E/17, which creates the Registry of Electricity Dependent for Reasons of Health (RECS), within the orbit of the National Ministry of Health, operating under the authority of the Undersecretariat for the Management of Health Care Services.

At the date of issuance of these condensed interim financial statements no further regulations have been issued concerning Law No. 27,351.

2.3 Gas transportation

On March 30, 2017, TGS and the Federal Government executed a new transitory agreement (the “2017 Transitory Agreement”). In this sense, ENARGAS issued Resolution No. I-4362 approving: (i) the RTI and the new tariff chart applicable to TGS; (ii) a Five-Year Investment Plan (April 2017 through March 2022) to be conducted by TGS; and (iii) a non-automatic mechanism for bi-annual updates in natural gas transportation tariffsand investment commitments. For the calculation of the adjustmentwill contemplate the evolution of the Wholesale Price Index published by the INDEC.

As regards the tariff scheme, the MEyM issued Resolution No. 74-E/2017 setting a limitation on the tariff increase resulting from the RTI process, which will be applied in three stages. The first stage will be effective as from April 1, 2017 and involves a 64.2% tariff increase. The remaining tariff increases will be granted as from December 1, 2017 (40% of the total increase) and April 1, 2018 (30% of the total increase).

2.4 Energy transportation

Pursuant to Resolution No. 524/16, which establishes the program applicable to the RTI process for Electric Power Transmission during 2016, on January 31, 2017, the ENRE issued Resolutions No. 66/17 and No. 73/17, which established, among others, the following provisions: (i) the tariffs in force for the 2017/2021 five-year period, and (ii) these resolutions provide for an investment plan for the 2017/2021 five-year period in the amounts of $3,336 million and $2,251 million for Transener and Transba, respectively.

Furthermore, the ENRE established the mechanism for adjusting the remuneration, the service quality system and the applicable penalties, the reward system and the investment plan to be executed by both companies during such period.

Due to the differences among the several tariff proposals submitted under the Full Tariff Review process initiated by the ENRE, on April 7 and 21, 2017, Transener and Transba, respectively, filed a Motion for Reconsideration and Appeal against ENRE Resolutions No. 66/2017, 84/2017, 139/2017, 73/2017, 88/2017 and 138/2017, whereby the ENRE approved the tariff system applicable to Transener and Transba, respectively, for the 2017/2021 period.

On October 31, 2017, ENRE Resolutions No. 516/2017 and 517/17 were notified, whereby the ENRE partially upheld the motions for reconsideration filed against ENRE Resolutions No. 66/17 and 73/17 by Transener and Transba S.A., respectively.

Furthermore, these resolutions provide for a new tariff scheme applicable to Transener and Transba S.A. retroactively to February 2017. The Company is currently analyzing them to evaluate their impact on such companies.

2.5 Refining and distribution

During 2017, the Company continued working in line with the provisions of Resolution No. 5/16 of the Secretary of Hydrocarbon Resources regarding fuel specifications.

As regards the quality of diesel oil, the Company is conducting a bidding process for the execution of the investments necessary for the construction and startup of a hydrotreating unit, which is expected to be operative in 2020, so that fuels should match the quality requirements set forth by Resolution No. 5/16.

This progress was duly informed to the authorities, thus meeting the provisions of Resolution No. 5/16 on the presentation of adequacy plans and investment programs necessary to meet fuel specifications.

As regards pump prices, during the nine-month period ended September 30, 2017, the Company has made adjustments pursuant to the Producers and Refiners Agreement promoted by the MEyM, which was adhered to by the Company and the main companies in this sector. The MEyM has informed of the suspension of the “Agreement for the Transition to International Prices” applicable to pump prices and to the cost of crude oil as a raw material effective as from October 1, 2017. Going forward, pump prices and the domestic price for crude oil barrels to be used as raw material for refining will be determined based on the domestic market rules.

The agreement had established a gradual convergence path for the domestic price of crude oil until achieving parity with international markets in 2017, as well as a price adjustment mechanism for the pump prices of refined products.

2.6 Oil and Gas Exploration and Production

2.6.1. Program for the Encouragement of Investments in the Development of Unconventional Natural Gas Production

On March 6, 2017 MEyM Resolution No. 46-E/2017 was published, which created the Program for the Encouragement of Investments in the Development of Natural Gas Production from Unconventional Reservoirs (the “Program”) seeking to encourage investments for the production of natural gas through unconventional methods in the Neuquén basin and effective until December 31, 2021.

To join this program, an investment plan should be submitted for concessions located in the Neuquén basin producing unconventional natural gas; the program consists of the payment of a compensation to be determined on a monthly basis by multiplying the sold gas volume from the covered concessions by the difference between its minimum price and its actual price (the average volume billed by each company in the domestic market). The minimum price is U$S 7.50 per million BTU for the year 2018, and it will be later decreased by U$S 0.50 per million BTU per year until reaching U$S 6.00 per million BTU for the year 2021. The company may collect compensations under this program as from the month following the submission of the application to join the program or the month of January, 2018, whichever is later, and until December 2021, both dates inclusive. Compensations assessed as indicated above will be payable as follows: 88% to the companies joining the program, and the remaining 12% to the province where the concession covered by the program is located. Compensations will be assessed in U.S. dollars but will be payable in Argentine pesos at the exchange rate for sales operations of Banco de la Nación Argentina effective on the last business day of the month corresponding to the production subject to compensation.

NOTE 2:(Continuation)

On November 2, 2017 MEyM Resolution No. 419/2017 was published in the Official Gazette. This resolution amends Resolution No. 46-E/2017 and divides concessions according to whether their initial unconventional production is higher or lower than 500,000 m3/d (monthly average for the July 2016-June 2017 period); in the case of concessions with a production higher than 500,000 m3/d, production is discounted for the payment of the compensation. The market average price is informed by the enforcement authority as the market weighted average, and covered concessions should have a 500,000 m3/d minimum average annual production by December 31, 2019.

The Company is currently analyzing several projects to submit under this call.

2.6.2. Natural Gas Price

On February 16, 2017 MEyM Resolution No. 29-E/2017 was published, which called for a Public Hearing to analyze new Transportation System Entry Point (PIST) prices for natural gas and propane gas for the distribution of undiluted propane gas through grids that would be valid for six-month periods as from April 1, 2017, in line with the gradual reduction of subsidies established by MEyM Resolution No. 212/16.

On March 30, 2017, after the conduct of the public hearing, the MEyM issued Resolution No.74-E/2017 establishing new PIST prices, which represented an improvement in the Company’s sales revenues.

2.6.3. Investment Agreement with YPF for the “Rincón del Mangrullo” Area

On August 1, 2017, YPF entered into an Agreement with the Province of Neuquén for the awarding of an unconventional exploitation concession in the Rincón del Mangrullo area, which will have to be approved by a provincial executive order.

The main commitments of the Agreement are as follows:

- A 35-year extension of the exploitation concession,

- A commitment to pay a bond, a corporate social responsibility contribution and the stamp tax for a total amount of U$S 20 million, and

- An investment commitment of U$S 150 million aiming to further the development of the Mulichinco formation (tight gas) and to explore the potential of the Lajas and Vaca Muerta formations.

Although PEPASA will participate in this new unconventional concession in Rincón del Mangrullo jointly with YPF, its investment commitment will amount to 30% of the total amount agreed upon between YPF and the Province of Neuquén as PEPASA’s Agreement with YPF does not include the Vaca Muerta formation.

2.6.4 MEyM Resolution No. 80-E/2017 – Acquisition of Natural Gas for the Sale of CNG.

On April 5, 2017, MEyM Resolution No. 80-E/2017 was published in the BO, which provides that, effective as from May 1, 2017, users acquiring natural gas for the sale of CNG will have the option of purchasing it either from distribution service providers in their distribution area or directly from natural gas producers or suppliers.

NOTE 2:(Continuation)

The Resolution provides that users electing to purchase natural gas directly from producers or suppliers should comply with the proportions assigned to each of the basins included in the area distributor’s tariff schemes, as well as with the applicable retained gas percentages.

In this line, users choosing to modify their purchase modality may not change it for a term of 12 months as from the exercise of such option.

Furthermore, if the user does not state its intention to modify its natural gas purchase option, it will be deemed that it has chosen to keep acquiring the whole service from the natural gas distribution service provider of its distribution area.

This resolution allows the Company to sell its natural gas production directly to CNG stations.

2.6.5. ENARGAS Resolution No. 4502/17 – Proceeding for Dispatch Administration.

On June 17, 2017, ENARGAS Resolution No. 4502/17 was published in the BO This Resolution approved the Procedure for Dispatch Administration by the Emergency Executive Committee (the “CEE”) and mainly provides for the following guidelines:

i) An emergency may be declared by carriers, distribution service providers or ENARGAS when it is considered that the priority demand is at stake;

ii) The carriers and/or ENARGAS will summon all CEE participants, including the loader which, based on the geographic area, may influence the resolution of the situation, as well as suppliers and direct users consuming more than 500,000 m3/day;

iii) In case the CEE fails to agree on how to distribute the supply to satisfy the unmet priority demand, ENARGAS will make a determination taking into consideration each producer’s available quantities minus the amounts it has already committed to meet another priority demand, with a progressive allocation until matching the proportional quota of each producer in the unmet priority demand.

iv) The information on the offer and demand will be provided by carriers and ENARGAS;

v) Decisions by a CEE will be binding on all participants in the gas industry;

vi) Carriers and distribution service providers will be responsible for the follow-up, control and compensation of imbalances; and

vii) Although the goal is that imbalances should tend to zero, tolerance bands are allowable, but loaders may not accumulate negative imbalances surpassing such tolerance bands.

Future decisions by this emergency committee may affect the Company’s sales revenues.

NOTE 4: ACCOUNTING POLICIES

The accounting policies applied in these unaudited condensed interim financial statements are consistent with those used in the financial statements for the last fiscal year prepared under IFRSs, which ended on December 31, 2016.

On June 2, 2017, the Company entered into cash settlement stock-based compensation agreements with its main executives officers based on market value of shares’ appreciation.

This compensation is recorded pursuant to the guidelines of IFRS 2. The fair value of the services received is measured through the estimation of the appreciation of the share using the Black-Scholes-Merton financial valuation model.

The fair value of the amount payable for the compensation agreements is accrued and recognized as an expense, with the resulting increase in liabilities. The liability is revalued on each balance sheet date. Any change in the fair value of the liability is recognized in profit or loss.

In Note 36 to the condensed interim financial statements the conditions of the compensation agreements, payment conditions and the main variables considered in the valuation model are detailed.

At the time of issuance of its next annual financial statements, the Company will apply the standards effective during fiscal year 2017 indicated in Note 4.2. to the Financial Statements as of December 31, 2016 (IAS 7: “Statement of Cash Flows” and IAS 12: “Income Taxes”). The Company estimates that these modifications will have no impact on the Company’s operating results or financial situation, but will only involve new disclosures.

As of September 30, 2016, the IASB has issued the following standards and interpretations:

IFRS 17 "Insurance contracts"

In May 2017, the IASB issued IFRS 17 that replaces IFRS 4, which was brought in as an interim standard in 2004 establishing the dispensation to carry on accounting for insurance contracts using national accounting standards, resulting in a multitude of different approaches. IFRS 17 establishes the principles for recognition, measurement, presentation and disclosure related to insurance contracts and shall by applied for annual reporting periods beginning on or after January 1, 2021, permitting early application for entities that apply IFRS 9 and IFRS 15.

The Company is analyzing the impact of the application of IFRS 17, however, it estimates that the application of IFRS 17 will not have an impact on the results of operations or financial position of the Company.

NOTE 4:(Continuation)

IFRIC 23 "Uncertainty over Income Tax Treatments"

In June 2017, the IASB issued IFRIC 23 clarifying how to apply IAS 12 when there is uncertainty over income tax treatments to determine income tax. According to the interpretation, an entity shall reflect the effect of the uncertain tax treatment by using the method that better predicts the resolution of the uncertainty, either through the most likely amount method or the expected value method. Additionally, an entity shall assume that the taxation authority will examine the amounts and has full knowledge of all related information in assessing an uncertain tax treatment in the determination of income tax. The interpretation shall apply for annual reporting periods beginning on or after January 1, 2019, permitting early application.

The Company is analyzing the impact of the application of IFRIC 23, however, it estimates that the application of IFRIC 23 will not have material impact on the results of operations or the financial situation of the Company.

Accounting Standards issued by the IASB applicable to fiscal years beginning on or after January 1, 2017

IFRS 15 “Revenue from Contracts with Customers”

This standard was issued in May 2014 and, in September 2015, its effective date was postponed to January 1, 2018. This standard establishes the principles applicable to the recognition of earnings and imposes information requirements on the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The basic principle implies the recognition of earnings involving the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is completing the analysis of the impact of its application, and expects to provide an estimate of such impact on the issuance of the financial statements as of December 31, 2017.

IFRS 9 “Financial Instruments”

This standard was amended in July 2014. The new version supersedes all previous versions of IFRS 9 and is effective for periods starting as from January 1, 2018. This version adds a new depreciation model based on expected losses and some minor modifications to the classification and measurement of financial assets. The Company has adopted the first phase of IFRS 9 as of the transition date and is finishing the analysis of the impact of the application of the modifications and remaining phases, and expects to provide an estimate of such impact on the issuance of the financial statements as of December 31, 2017.

No significant changes have arisen in risk management policies since last year.

NOTE 7: INVESTMENTS IN SUBSIDIARIES

Merger of Subsidiaries

The following corporate reorganizations seek to derive important benefits for the Group, as they will allow for a higher operating efficiency, an optimized use of available resources, the leveraging of technical, administrative and financial structures, and the implementation of converging policies, strategies and goals. Furthermore, the high complementarity between the participating companies will be leveraged, thus reducing costs resulting from the duplication and overlapping of operating and administrative structures.

The merger's effective datedetailed belowwas fixed on January 1, 2017, as from which date the transfer to the acquiring companies of the whole net worth of the acquired companies became effective, all the rights and obligations, assets and liabilities of the acquired companies thus being incorporated into the acquiring companies' net worth, all of which subject to the corresponding corporate approvals under the applicable law, the approval by the ENREin the corresponding caseand the registration with the Public Registry of Commerce of the merger and the dissolution without liquidation of the acquired companies.

These reorganizations were implemented by means of a merger through absorption process, whereby the acquired companies will be dissolved without going into liquidation, subject to the provisions of the prior merger through absorption commitment, and sections 82 through 87 of theLey General de Sociedades No. 19,550 (Argentine Business Companies Law, or “BCL”) and its amending provisions, the CNV provisions, the BCBA Listing Rules and other provisions, the IGJ provisions and all other applicable legal and regulatory provisions in force.

Corporate reorganizations correspond to business combinations between companies under common control, and therefore there is no effect in these unaudited consolidated condensed interim financial statements.

7.1.CTLL, EASA and IEASA

On December 7 and 22, 2016, the Board of Directors of CTLL, EASA and IEASA resolved to initiate all necessary tasks and procedures for the merger through absorption among CTLL, as absorbing company, and EASA and IEASA, as absorbed companies.

As part of the analysis of this reorganization and in order for the process to be feasible, EASA's management concluded that it was necessary that the debt EASA held with holders of Class A and B Discount Corporate Bonds issued on July 19, 2006 and maturing in 2021 be capitalized.

On March 27, 2017, EASA's Extraordinary General Meeting of Shareholders approved the capitalization of the totalof the negotiable obligations mentioned above. The capitalization was accepted by PISA in its capacity as sole holder.

On May 18, 2017, the Extraordinary Meetings of Shareholders of the involved companies resolved to call for an adjournment in the merger approval discussions, subject to the ENRE’s approval, which were later resumed on June 16, 2017, although deferring the consideration of the merger as the authorization.

By Board Resolution No. 347 passed on August 11, 2017, the ENRE resolved, by a majority of votes, to reject the request for authorization submitted by CTLL. CTLL has appealed this Resolution before the SEE timely and in due form as it considers that it does not conform to law.

As at the issuance of these Condensed Interim Consolidated Financial Statements, the SEE has not issued a decision in this respect. Should the required approvals fail to be obtained, the Company will have to roll back the effects of the merger and, in accordance with this change of scenario, it may have to derecognize assets for deferred taxes recognized during this period.

7.2.PACOSA and WEBSA

On December 7, 2016, the Boards of Directors of PACOSA and WEBSA resolved to begin all necessary tasks and procedures for the merger through absorption between PACOSA, as absorbing company, and WEBSA as absorbed company.

Pursuant to the prior merger commitment approved by PACOSA and WEBSA's Boards of Directors on March 7, 2017, each WEBSA shareholder will receive, as consideration for each share it held before the merger, 3.305882 ordinary shares of PACOSA with a face value of $1 each, and each granting the right to one vote.

As a result of the above-mentioned exchange ratio, PACOSA will issue 13,310,739 common shares in book-entry form with a face value of $1 each, and each granting the right to one vote and, after the merger through absorption is effected, PACOSA’s capital stock will consist of 33,010,739 common shares.

NOTE 28: EARNING (LOSS) PER SHARE

a) Basic

Basic earnings (loss) per share are calculated by dividing the result attributable to the Company’s equity interest holders by the weighted average of outstanding common shares during the period.

b) Diluted

Diluted earnings (loss) per share are calculated by adjusting the weighted average of outstanding common shares to reflect the conversion of all dilutive potential common shares.

Potential common shares will be deemed dilutive only when their conversion into common shares may reduce the earnings per share or increase losses per share of the continuing business. Potential common shares will be deemed anti-dilutive when their conversion into common shares may result in an increase in the earnings per share or a decrease in the losses per share of the continuing operations.

The calculation of diluted earnings (loss) per share does not entail a conversion, the exercise or another issuance of shares which may have an dilutive or anti-dilutive effect on the results per share whereby as of September 30, 2016, the diluted earnings per share is equal to basic. As of September 30, 2017, the Company does not hold any significant potential dilutive shares, therefore there are no differences with the basic earnings (loss) per share.

NOTE 33: ECONOMIC AND FINANCIAL SITUATION OF DISTRIBUTION SEGMENT

The measures adopted by the Federal Government, aimed at resolving the electricity rate situation of the electric power sector during 2016, together with the application of the RTI as from February 1, 2017 are making it possible to gradually restore Edenor’s economic and financial equation; therefore, Edenor’s Board of Directors is optimistic that the new electricity rates will result in Edenor’s operating once again under a regulatory framework with clear and precise rules, which will make it possible to not only cover the operation costs, afford the investment plans and meet debt interest payments, but also deal with the impact of the different variables that affect Edenor’s business.

As of September 30, 2017, Edenor’s comprehensive income for the nine-month period amounts to $ 678 million – profit-, whereas the working capital totals $ 4.1 billion – deficit-, which includes the amount owed to CAMMESA for $ 4.4 billion (principal plus interest accrued as of September 30, 2017).

Edenor’s equity and negative working capital reflect the deteriorated financial and cash position Edenor still has as a consequence of both the Federal Government’s delay in the compliance with certain obligations under the Adjustment Agreement and the constant increase in operating costs in prior fiscal years, which Edenor absorbed in order to comply with the execution of the investment plan and the carrying out of the essential operation and maintenance works necessary to maintain the provision of the public service object of the concession in a satisfactory manner in terms of quality and safety.

Despite the previously described progress achieved with regard to the completion of the RTI process, at the date of issuance of these condensed interim financial statements, the definitive treatment to be given, by the MEyM, to all the issues resulting from the non-compliance with the Adjustment Agreement, including the remaining balances and other effects caused by the partial measures adopted, has yet to be defined.

These issues, among other, are the following:

i) the treatment to be given to the funds received from the Federal Government through the loans for consumption (mutuums) agreements entered into with CAMMESA for the fulfillment of the Extraordinary Investment Plan, granted to cover the insufficiency of the FOCEDE’s funds;

ii) the conditions for the settlement of the balance outstanding with CAMMESA at the date of issuance of SEE Resolution No. 32/15;

iii) the treatment to be given to the Penalties and Discounts determined by the ENRE, whose payment/crediting is pending.

In this regard, on April 26, 2017 Edenor was notified that the MEyM had provided that, once the RTI process is completed, the SEE -with the participation of the Under-Secretariat for Tariff Policy Coordination- and the ENRE, shall determine in a term of 120 days whether any pending obligations exist until the effective date of the electricity rate schedules resulting from the RTI and in connection with the Adjustment Agreement entered into on February 13, 2006. In such a case, the treatment to be given to those obligations shall also be determined. Edenor has submitted the information requested by the MEyM in the framework of this requirement. At the date of issuance of these condensed interim financial statements such situation is still pending resolution.

NOTE 34: DISCONTINUATION OF THE ARBITRATION PROCEEDING BEFORE THE ICSID

On March 28, 2017 the Secretariat of the World Bank’s International Centre for Settlement of Investment Disputes ("ICSID") took note of the discontinuance of the arbitration proceeding brought by EDF International and EASA in August 2003 regarding the breach of Edenor's concession agreement as a result of the passing of Public Emergency and Exchange Rate Regime Reform Act No. 25,561. The claimants' waiver was a condition of Edenor's Contract Renegotiation Memorandum of Understanding which had to be met after the issuance of the tariff scheme resulting from the Full Tariff Review, which was implemented through ENRE Resolution No. 63/2017 dated February 1, 2017 and is effective as from such date.

NOTE 35: REGULARIZATION REGIME (MORATORIUM)

Between the 29 and the 31 of March 2017, the Company adhered to the regularization regime (moratorium) provided for Law No. 27,260 in relation to certain tax claims and provisions. The Company related liabilities were mainly attributable to contingencies identified in Petrobras’s acquisition process including interpretation differences with the Argentine tax authority regarding i) the time of recording well abandonment expenses for income tax purposes, ii) the exemption from the Tax on Personal Assets as Substitute Taxpayer for the shareholder PPSL; iii) the Tariff heading used by the Company for certain exported products; and iv) inaccurate customs regarding the importation of a turbine supplied by Siemens Germany, including certain spare parts that had not been required nor declared by the Company. In relation to the last matter described before, the Company entered into an agreement with Siemens pursuant to which Pampa will receive the reimbursement of related incurred costs. As of December 31, 2016, the carrying amount of the matters that were included in the moratorium amounted to $ 1,332 million and $ 668 million disclosed as provisions and tax payables, respectively.

As the adhesion to the regularization regime established benefits of releasing tax fines and reducing compensatory interests, the Company has recorded on March 31, 2017 a net gain after income tax effects of $335 million, which in turn, generated the payment of approximately $171 million to Petrobras Brazil as contingent consideration payable in accordance to the share purchase agreement for the acquisition of Petrobras.On April 18, 2017, the Company paid this obligation.

The plan was ratified and approved by the ordinary and extraordinary shareholders’ meeting held on April 18, 2017.

At the date of issuance of these condensed interim financial statements, Edenor awarded a total of 1,618,332 shares to executive directors and managers as additional remuneration for their performance in special processes developed during fiscal year 2016.

(in millions of Argentine Pesos (“$”) – unless otherwise stated)

NOTE 36:(Continuation)

In accordance with international practices, the purpose of these agreements is to efficiently align the Senior Management’s interests with those of the Company and its shareholders, creating value for them only inasmuch as value is generated for shareholders, that is, if the Company’s market value increases.

Under these agreements, the Senior Management will be entitled to a fixed compensation and an annual, variable and contingent long-term compensation related to the Company’s annual market value appreciation, with a cap on the Company’s operating income

With the purpose of avoiding duplication, any analogous compensation that the Senior Management had received from any of the Company’s subsidiaries, will be deducted from the compensation amount in proportion to the Company’s interests in such subsidiaries.

As of September 30, 2017, the Company recognized in its Statement of Comprehensive Income $ 155 million as the cost of such compensation indicated, offsetting entries $ 145 million in Other Payables and $ 10 millionin Equity.

NOTE 37: CORPORATE REORGANIZATION

2016 Reorganization

Following the acquisition of Petrobras Argentina, Pampa Energía started a corporate reorganization plan with the purpose of simplifying and maximizing the efficiency of the Company’s structure. The proposed reorganizations will allow the Company to derive significant operative and economic advantages, including, but not limited to, those associated with a higher operating efficiency; an optimized use of available resources, and the streamlining of technical, administrative and financial structures.

In this line, the Company, as absorbing company, party of the first part, and Petrobras Argentina S.A., Petrobras Energia Internacional S.A. and Albares Renovables Argentina S.A., as absorbed companies, parties of the second part, the Shareholders’ meetings executed the Final Merger Agreement at the beginning of this year. As of the issuance of these financial statements, the merger is pending registration with the Public Registry, to which effect the Company is filing all applicable presentations with the corresponding bodies.

2017 Reorganization:

On June 26, 2017, the Board of Directors instructed the Company’s Management to start the proceedings allowing to evaluate the benefits of a merger through absorption process between the Company, as absorbing company, and certain companies of the group, as absorbed companies.

(in millions of Argentine Pesos (“$”) – unless otherwise stated)

NOTE 37:(Continuation)

On September 22, 2017, the Company’s Board of Directors informed that the companies which will take part in these merger will be the Company, as absorbing company, and BLL, CTG, CTLL, EG3 Red, INDISA, INNISA, IPB, PPII, Transelec and PEPASA, as absorbed companies, in line with the tax neutrality terms set forth by Section 77 and following ones of the Income Tax Act. Furthermore, it determined that the merger would become effective on October 1, 2017, date as from which the transfer of the absorbed companies’ equity to the absorbing company will become effective and, therefore, all their rights and obligations, assets and liabilities will become incorporated into the absorbing company’s equity, all of which subject to the corresponding corporate approvals under the applicable law and the registration with the Public Registry of Commerce of the merger and the dissolution without liquidation of the absorbed companies.

Except for PEPASA, CTG, INNISA and INDISA, which have a non-controlling interest, there will no exchange ratio for the other companies subject-matter of the merger as the Company directly and/or indirectly holds 100% of the capital stock of such companies.

Lastly, since PEPASA and the Company’s assets are subject to the public offering system and listed in ByMA, the Board of Directors decided to propose to the Shareholders’ Meeting an exchange ratio based on the volume-weighted average price of the Company and PEPASA’s shares traded over the last six months, determined retroactively as from the Board meeting’s date, with a resulting exchange ratio of 2,2699 common shares in book-entry form with a face value of $ 1 each and each granting the right to one vote for each PEPASA common share in book-entry form with a face value of $ 1 and granting the right to one vote.

This merger will entail important benefits for the Company and all its corporate group, as it will allow for enhanced operating efficiency; an optimized use of available resources; the leveraging of technical, administrative and financial structures; and the implementation of converging policies, strategies and goals. Furthermore, the high complementarity between the participating companies will be leveraged, thus reducing costs resulting from the duplication and overlapping of operating and administrative structures.

The Absorbing Company and the Absorbed Companies are currently performing the necessary procedures before the applicable entities in order to obtain the authorizations, registrations and recordings necessary for the Absorbing Company to operate as the continuing company in the merger. Notwithstanding that, in view of the need to request and obtain a large number of authorizations, registrations and recordings which must be granted by several national, provincial and municipal entities and the impossibility to obtain such approvals on a simultaneous basis, some absorbed companies will exceptionally continue operating and performing certain activities on behalf and at the expense of the Absorbing Company with the sole purpose of not hindering their course of business until all authorizations, registrations and recordings are finally obtained.

Edenor - MEyM Resolution No. 840-E/17

On October 4, 2017, by means of Resolution No. 840-E/17, the MEyM recognized in favor of Edenor an amount of $ 323 million for the works carried out prior to the ending of the FOCEDE, requiring as a condition for such recognition to take place that Edenor notify both the Energy Secretariat and the ENRE of its decision to not only abandon any and all administrative and/or judicial claims filed, but also waive its right to any other future claim against the Federal Government, the MEyM, the SEE, the ENRE and/or CAMMESA based on the FOCEDE trust.

In this regard, on October 9, 2017, Edenor expressed that it had no administrative or judicial claims against such institutions on the aforementioned ground, and that the recourse (“recurso directo”) filed in 2015 against ENRE’s Resolution No. 356/14, pursuant to which a fine had been imposed on the Company due to the non-application of the FOCEDE’s remaining funds in due time, was not considered within the scope of such requirement.

On October 31, 2017, MEyM Resolution No. 415-E/2017 was published in the BO, which modifies the procedure to determine the purchase price for corn- or sugarcane-based bioethanol to be blended with gasoline for automotive use. This modification results in a decrease in the purchase costs of bioethanol, a raw material which should make up 12% of the volume of gasoline for automotive use sold in the Argentine territory.

Therefore, on November 4, 2017, Pampa accompanied the measure adopted by the major market players by reducing suggested gasoline prices at gas stations, thus transferring this cost reduction to end consumers, except in the Provinces of Chubut and Santa Cruz.

These interim financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any materialmodifications that should be made to the accompanying unaudited consolidated condensed interim financial statements for them to be in conformity with International Accounting Standard 34 “Interim Financial Reporting”, as issued by the International Accounting Standard Board.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidatedstatement of financial position as of December 31, 2016, and the related consolidated statements of comprehensive income (loss), changes in equity and of cash flows for the year then ended (not presented herein), and in our report dated April 26, 2017, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidatedstatement of financial position as of December 31, 2016, is fairly stated, in all material respects, in relation to the consolidatedstatement of financial position from which it has been derived.
