NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF JUNE 30, 2013 AND COMPARATIVES

(amounts in thousands of pesos, except where expressly stated otherwise)

1.	GENERAL INFORMATION

MetroGAS S.A. (“MetroGAS” or the “Company”) is a sociedad anónima organized under the laws of the Republic of Argentina. The registered office and principal place of business is located at Gregorio Aráoz de Lamadrid 1360 – Ciudad Autónoma de Buenos Aires.

The Company was formed in 1992 and on December 1, 1992 it was registered as a corporation pursuant the laws of the Republic of Argentina under number 11,670, Book 112, Volume A of Sociedades Anónimas. The term of duration of the Company expires on December 1, 2091 and its principal business is the provision of natural gas distribution services.

On November 2, 1994, the Argentine Securities Commission (“CNV”), pursuant to Resolution No. 10,706, authorized to public offering all the Company’s outstanding shares that at such date composed the capital stock. American Depositary Shares (“ADSs”) were issued in the United States and were registered with the Securities and Exchange Commission (“SEC”). The Shares of the Company are listed on BCBA and its ADSs on the New York Stock Exchange (“NYSE”), respectively. On June 17, 2010, the NYSE informed that MetroGAS ADSs had been suspended from trading as a result of the Company´s filing for reorganization proceeding.

MetroGAS’ controlling shareholder is Gas Argentino S.A. (“Gas Argentino”) whose principal business is the investment (see Note 2.1).

MetroGAS controls MetroEnergía S.A. (“MetroEnergía”) whose principal business is the sale of natural gas and/or transport on its own behalf or on account of third parties.

2.	ECONOMIC AND FINANCIAL POSITION AND REGULATORY FRAMEWORK

The changes in the economic conditions of the country and the amendments introduced by the Public Emergency Law towards the end of 2001, have impacted the economic and financial position of the Company affected by the suspension of the original regime of tariffs adjustment, added to the increase in the operating costs to maintain the quality of service. The Company estimates that, if the conditions as of the date of issuance of these financial statements continue, the situation will continue to deteriorate, for this reason, the management has evaluated a variety of measures to mitigate the impact of the current financial situation, including:

escalating the Company claims to Argentine authorities on the approval of tariff increases (including the pass-through of municipal levies);

procuring the strict management of cash-flow and control our expenditures;

requiring additional capital contributions from shareholders;

renegotiating payment conditions with our principal suppliers and the Trust Funds; and

obtaining financing from third parties.

The Company is under a renegotiation process of certain terms of the License with the Argentine Government in order to oppose the negative impact produced by the mentioned circumstances, which situation has not been resolved to the date of these interim financial statements.

In this context, in the fiscal year ended December 31, 2012 the Company registered a significant increase in the operating loss. Likewise, as of June 30, 2013, the Company registered cumulative losses amounting to Ps. 735,292 thousand and the consolidated negative working capital to Ps. 100,440 thousand.

METROGAS S.A.

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF JUNE 30, 2013 AND COMPARATIVES

(amounts in thousands of pesos, except where expressly stated otherwise)

These consolidated financial statements have been prepared using accounting standards applicable to a going concern. As of the date of issuance of these financial statements, it is neither possible to foresee the outcome of the tariff negotiation process nor to determine its final consequences on the Company’s results and operations. The above mentioned circumstances raise substantial doubt about the Company’s ability to continue as a going concern. However, the Company’s consolidated financial statements do not include any adjustments or reclassifications, if any, that might be required from the unsuccessful outcome of the situation described above.

In Note 1 of the attached Annex I which includes information as of December 31, 2012, the aspects related to the economic and financial situation and regulatory framework are described. There follow the significant developments occurred during the six months period ended June 30, 2013:

2.1	Change in Company control

On April 26, 2013, MetroGAS was informed of Resolution ENARGAS No I/2566 D, dated April 19, 2013, whereby ENARGAS approved the purchase by YPF Inversora Energética S.A. of 54.67% of Gas Argentino. Class A shares from BG Inversiones Argentinas S.A. and of 2.73% of MetroENERGÍA S.A. shares from BG Argentina S.A., without prejudice of the involvement of Comisión Nacional de Defensa de la Competencia (National Committee for the Defense of the Competition).

On May 3, 2013, Gas Argentino reported that BG Inversiones Argentinas S.A. had transferred to YPF Inversora Energética S.A. (“YPFIESA”) 46,010,284 ordinary, registered shares with nominal value of $ 1 and one vote per Class A share, representative of 54.67 % of the capital stock of Gas Argentino, owner of 70% of MetroGAS’s shares. Thus, YPF S.A. through YPFIESA obtained 100% of the capital stock and votes of Gas Argentino and it will indirectly have, through Gas Argentino, 70% of the capital stock and votes of MetroGAS (See Note 28 – Subsequent Events).

2.2	MetroGAS Reorganization Proceeding

In compliance with the reorganization proceeding as described in Note 1.1 to the attached Annex I, on January 11, 2013, MetroGAS issued new notes which were delivered in exchange to financial creditors and non-financial creditors who were admitted and declared acceptable as detailed in Note 16.

On February 1 and February 13, 2013, MetroGAS submitted before the intervening Court the documentation evidencing compliance with the debt exchange and the issuance of the new notes in order to obtain the removal of all general inhibitions and the legal declaration of the accomplishment of the proceeding within the terms and conditions of Section 59 of the Argentine Bankruptcy Law.

On March 26, 2013, the MetroGAS Board of Directors decided by a majority of votes to capitalize 100% of the portion subject to capitalization of interest payable on June 30, 2013 and to issue Additional Negotiable Obligations for such capitalization.

Furthermore, the Board also decided to issue New Negotiable Obligations for the new unsecured creditors, as long as their credits have been verified by a ruling in the Reorganization Proceedings.

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF JUNE 30, 2013 AND COMPARATIVES

(amounts in thousands of pesos, except where expressly stated otherwise)

On July 25, 2013, MetroGAS issued:

Negotiable Obligations of Late Verification:

Series A-U: U$S 5,087,459

Negotiable Obligations of Capitalization

Additional Series A-L: U$S 6,756,665

Additional Series A-U: U$S 704,581

2.3	MetroGAS Intervention

On May 31, 2013, ENARGAS published Resolution ENRG I-2,587/13 providing for the termination of the intervention of that entity at MetroGAS. The intervention had been originally established in June 2010 as a consequence of MetroGAS’ Shareholders Reorganization Proceedings.

2.4	Regulatory Framework

2.4.1

Tariff Renegotiation – Charge Resolution ENARGAS 2,407/12

On March 27, 2013, MetroGAS received, from the Execution Committee, the notification of approval of the Consolidation and Expansion Investment Plan submitted on February 1, 2013.

2.5	Incentive Policies

There are various schemes fostered by the National Government to boost the natural gas industry which, although initially have no direct impact on MetroGAS, nor do they impose any obligations on the company, might actually have favorable consequences considering that one of their main objectives is to increase natural gas injections. The various schemes are described below:

2.5.1

“Plan Energía Total” (Total Energy Plan)

Within the framework of this Plan, ENARSA injects certain volumes for CNG filling stations above the volumes injected by producers according to the specific auctions carried out by MEG (Gas Electronic Market). On July 10, 2013, ENARGAS issued Resolution ENRG I-2,621/13 that provided that the regional distributors shall invoice the volumes injected by ENARSA on behalf of the latter together with the billing for the natural gas distribution and transportation service, and shall then render all accounts for the amounts thus invoiced. The Resolution specifically states that the higher costs that the invoicing on behalf of ENARSA generates to Distributors may not be passed through to consumers but they will eventually be covered within the framework of specific agreements that shall be negotiated and agreed between the Distributors and ENARSA resulting from that regulation. The operation in question applies to the volumes injected by ENARSA as from June 2013.

2.5.2

Program to Encourage the Surplus Injection of Natural Gas

Resolution 1/2013 dated January 18, 2013, of the Strategic Planning and Coordination of the National Plan of Hydrocarbon Investments, approved the Program to Encourage the Surplus Injection of Natural Gas with the objective of encouraging gas producers to increase their injections for supplying the internal market through the acknowledgement of higher prices above those effectively charged through the National Government’s compensation system. Via Resolutions 7/2013 and 8/2013 issued by the above mentioned Committee on July 4, 2013 (i) the deadline for adhering to the abovementioned Program, originally set for June 30, 2013, was extended until August 16, 2013, and (ii) a mechanism was approved for making advanced payments to producers of up to 75% of the compensations due to them for their surplus injections of natural gas.

(amounts in thousands of pesos, except where expressly stated otherwise)

2.5.3

Scheme for the Promotion of Investment for Hydrocarbon Exploitation

On July 15, 2013, the Official Gazette published Executive Order PEN 929/13 which provided the creation of a Scheme for the Promotion of Investments for Hydrocarbon Exploitation with the objective, among others, of obtaining the self-supply of hydrocarbons.

The principal items of this new scheme are:

1. Submission of investment projects for over U$S1,000,000,000 in 5 years.

2. As from the fifth year after Project start up, free availability of 20% of hydrocarbons to be marketed in the external market at 0% exportation duties.

3. Free availability of 100% of the currency resulting from such exportation without the obligation of settling them locally provided the previous income of U$S 1,000,000,000 of committed investment has been credited.

4. Price and currency compensation mechanism in the event that, due to a shortage in the local market, exports were suspended, and to ensure producers that (i) their 20% of not exported hydrocarbons would be collected locally in pesos at reference export prices and (ii) they may buy freely available dollars with those pesos.

5. Organization of the “Concession for the Non-Conventional Exploitation of Hydrocarbons” (shale gas, shale oil, tight sands, tight gas, tight oil and/or coal bed methane) for 25 years plus a 10-year extension.

6. The application authority is the Strategic Planning and Coordination Committee of the National Plan of Hydrocarbon Investments, in charge of scheme regulation.

3.	BASIS FOR PRESENTATION AND ADOPTION OF THE INTERNATIONAL FINANCIAL REPORTING STANDARDS (“IFRS”)

3.1	Adoption of the International Financial Reporting Standards

The CNV has set forth, through Resolution No. 562/09 and No. 576/10, the enforcement of Technical Resolution (“TR”) No. 26 and 29 of the Argentine Federation of Professional Councils in Economic Sciences (“FACPCE “) which adopt the International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”) for entities included in the public offer regime of Law No. 17,811 due to their capital stock or to their notes, or those that have applied to be included in said regime.

On January 24, 2012, in order to evaluate the applicability and impact of IFRIC 12 “Service Concession Arrangements” for registrant licensees of the public service of natural gas transport and distribution, as well as, their controlling companies, the CNV issued Resolution 600 extending the enforcement of the IFRS to the fiscal year commencing on January 1, 2013. Afterwards, on December 12, 2012, the CNV issued Resolution 613 establishing reasons and cause on which the licensees of the public service of natural gas transport and distribution and their controlling companies are not included in the scope of the IFRIC12. See “Key Accounting Estimates and Judgments” in Note 3, Annex I.

(amounts in thousands of pesos, except where expressly stated otherwise)

Consequently, the application of the IFRS is compulsory for the Company as from fiscal year commenced on January 1, 2013, being these, the first financial statements for the six months period submitted under these standards. The transition date to the IFRS for the Company as established in the IFRS 1 “First Time Adoption of IFRS” is January 1, 2012.

These condensed consolidated interim financial statements for the six months period ended June 30, 2013 have been prepared under the International Accounting Standard (“IAS”) 34 “Interim Financial Reporting” and the IFRS 1 “First Time Adoption of IFRS”. The condensed consolidated interim financial statements have been prepared pursuant the accounting policies that the Company expects to adopt in its annual consolidated financial statements as of December 31, 2013. The accounting policies are based on the IFRS issued by the IASB and the interpretations issued by the IFRIC which are expected to be applicable as of said date.

The Company financial statements were previously prepared in accordance with the Argentine GAAP. The Argentine GAAP differ in some areas from the IFRS. To prepare these condensed consolidated interim financial statements, the Company has modified certain accounting policies of appraisal and exposure previously applied under the Argentine GAAP to conform the IFRS. The principal accounting policies are described in the following notes.

The comparatives figures and those corresponding to the transition date (January 1, 2012) have been modified to reflect those adjustments. In Note 3.6 there appears an adjustment among the figures of the net worth, related to the consolidated financial statements issued under the Argentine GAAP as of June 30, 2012, as of the transition date (January 1, 2012) and as of the adoption date (December 31, 2012) and of the results and other comprehensive results for the six months period ended June 30, 2012 and for the fiscal year ended December 31, 2012 and the amounts submitted under the IFRS in these condensed consolidated interim financial statements, as well as the effects of the adjustment in the cash flows.

3.2	Filing of These Interim Financial Statements

These condensed consolidated interim financial statements should be read together with the Company annual financial statements as of December 31, 2012 prepared in accordance with the Argentine GAAP. Additionally, in the attached Annex I to these financial statements there appear information under the IFRC as of December 31, 2012 necessary for understanding these condensed consolidated interim financial statements.

These condensed consolidated interim financial statements have been approved by the Board of Directors for issuance on August 14, 2013.

The condensed consolidated interim financial statements for the six months periods ended June 30, 2013 and 2012 have not been audited. The Company estimates that they include all the adjustments necessary to fairly present the results for each period.

3.3	Seasonable Character of the Operations

The sales and profits of the Company are highly influenced by the weather conditions prevailing in Argentina. The natural gas demand and consequently, the MetroGAS sale and profits are considerably higher during the winter months (May to September) due to the volumes of gas sold and to the tariffs mix that affects the sales profit and net margin.

3.4	Application of International Financial Reporting Standards

IFRS 1 allows to the entities that adopt for the first time the standards to consider some sole exemptions and exceptions to the principle of retroactive application of certain IFRS in force. Said exceptions have been foreseen by the IASB to simplify the first application of said rules.

- Optional exemptions adopted by the Company:

Cost attributed to Properties, plant and equipment and Investment properties: the cost of Properties, plant and equipment and Investment properties, restated under the accounting standards in force have been adopted as deemed cost as of the transition date to IFRS, since that cost is similar to the cost or depreciated cost under the IFRS, adjusted to reflect the changes in a general or specific prices index. Likewise, the IFRS establish alternative criteria for the measurement after the initial recognition of each class of property that composes the items of Properties, plant and equipment, foreseeing that the “cost model” or “revaluation model” is to be used. The Management of the Company has elected to continue applying the “cost model” to all classes of property which compose Properties, plant and equipment and Investment properties.

Leasing: The Company determined if the agreements in force as of the date of transition to IFRS included a leasing, as from the consideration of facts and circumstances existing as of said date.

- Mandatory exceptions applicable to the Company:

Estimates: the estimates carried out by the Company under IFRS to the date of transition to IFRS are consistent with the estimates carried out as of the same date under Argentine GAAP.

Derecognition of financial assets and liabilities: the Company, pursuant IFRS 1, applied the IFRS 9 prospectively to the financial liabilities written off as a result of the restructuring of its financial debt carried out on May 12, 2006 as it did not have the necessary information to apply the IFRS 9 upon initial recognition of these transactions.

The following mandatory exceptions provided by IFRS 1 have not been applied as they were not identified significant operations for the Company:

· Hedge accounting

· Non-controlling interests

· Embedded derivatives.

3.5	Major Differences in Valuation Criteria

The main differences we have identified between Argentine GAAP and IFRS are described below:

Inventories

Under IFRS, materials were reclassified to Properties, plant and equipment and valued at the lesser of cost or net realizable value, considering an allowance for obsolescence of materials, if applicable, while under Argentine GAAP they were valued at their replacement cost.

Other Receivables

Under Argentine GAAP the Company had been recognizing as receivables any charges transferable to customers under the regulatory framework established in its License and for which evidence of effective recognition in the past was available, as described in Note 1.3.8 of the Annex attached to the consolidated financial statements. In spite of the fact that the Company has satisfied all necessary requirements for approval, the issuance of a resolution authorizing the effective inclusion of those charges in bills to customers by different governmental agencies has been delayed. In the absence of this resolution and under IAS 18, any payments made may not be taken as receivables for their whole nominal amount until a resolution approving and implementing the relevant transfer will have been issued.

In addition, under Argentine GAAP, the Company has recognized as receivables any deferred income tax asset balances and income tax or minimum presumed income tax credits which are deemed recoverable based on an estimation of future taxable profits. If a company suffers recurrent tax losses, IAS 12 – Income Tax allows only the recognition of deferred income tax assets and income tax credits provided that they may be offset against deferred income tax liabilities.

Tax Effect of IFRS Reconciling Items

This adjustment represents the effect of deferred income tax at a 35% rate on the IFRS reconciling items described above.

The Company has identified major differences regarding the valuation of its subsidiary MetroENERGÍA and has not detected substantial changes between IFRS and Argentine GAAP.

3.6	Required Reconciliations

In accordance with the provisions of FACPCE, TR No. 26 and No. 29, the reconciliation of net worth as determined under Argentine accounting standards and under IFRS as of December 31, 2012 and January 1, 2012, and the reconciliation of comprehensive income for the six-month period ended on June 30, 2012 and the fiscal year ended on December 31, 2012, are included below. In this respect, when preparing these reconciliations, the Company has taken into account those IFRS that it believes will be applicable for the preparation of its financial statements as of December 31, 2013. The items and figures contained in this note are subject to change and may only be considered final when the annual financial statements for the fiscal year when IFRS will be applied for the first time will be prepared. Also, the Company has opted for an early adoption of IFRS 9.

4.	ACCOUNTING POLICIES

The accounting policies adopted for these condensed consolidated interim financial statements are consistent with the policies used to prepare information under IFRS as at December 31, 2012, which are detailed in Annex I attached hereto and based on the IFRS expected to be in effect as of December 31, 2013.

For purposes of accounting for the exchange for new notes under debt restructuring proceedings effected on January 11, 2013, as described in Note 16 on financial debt, the Company has followed the guidelines established in IFRS 9 – Financial Instruments: Recognition and Measurement.

IFRS 9 provides that in the event of an exchange between an existing borrower and lender of debt instruments with substantially different terms, the transaction must be accounted for as an extinguishment of the original financial liability and the consequent recognition of a new financial liability. The difference between the carrying amount of the extinguished financial liability and any amount paid as consideration, which will include any assigned assets other than cash or assumed liability, must be recognized as profit or loss for the fiscal year. The Company believes that the terms of the reorganization debt to be exchanged are substantially different from those of the new notes and has consequently recorded the exchange of debt in accordance with the above guidelines. Also, pursuant to IFRS 9, the new notes have been initially recognized at fair value, net of any incurred transaction costs, and are subsequently measured at amortized cost.

METROGAS S.A.

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF JUNE 30, 2013 AND COMPARATIVES

(amounts in thousands of pesos, except where expressly stated otherwise)

For purposes of initial recognition, the fair value of the new debt issued has been estimated on the basis of discounted cash flows, absent any prices quoted in an active market which may be significant for the amount issued.

5.	KEY ACCOUNTING ESTIMATES AND JUDGMENTS

The preparation of consolidated financial statements as of a specified date requires the Company to make estimates and judgments that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities as of such date, and the reported amount of revenues and expenses during the year. The Company makes estimates in order to be able to calculate at a specified time, for instance, the allowance for doubtful accounts, depreciation, recoverable value of assets, income tax charges and provision for contingencies. Actual future income may differ from the estimates and judgments made as of the date of preparation of these condensed consolidated interim financial statements.

For the preparation of these condensed consolidated interim financial statements, the key judgments made by the Company when applying its accounting policies and the sources of information used for the respective estimates are consistent with those that were applied in the consolidated financial statements for the fiscal year ended on December 31, 2012, which are detailed in Note 3 of Annex I, including additional information as of December 31, 2012.

6.	FINANCIAL RISK MANAGEMENT

The business of the Company exposes the Company to various financial risks: market risk, credit risk and liquidity risk. No significant changes have occurred during the six-month period ended on June 30, 2013 in relation to financial risk factors and management policies with respect thereto. They are detailed in Note 4 of Annex I attached hereto, including information as of December 31, 2012.

7.	SEGMENT REPORTING

The Company operates mainly in the segments of gas distribution, natural gas commercialization, and through MetroENERGÍA, of gas transportation services on its own account and on behalf of or in association with third parties.

The issuance of new notes was approved by a decision of the Issuer Department of the CNV dated December 26, 2012, under the Global Notes Program of MetroGAS, for a nominal value of up to U$S 600 million.

The Company issued the following notes to be delivered in exchange for existing notes:

Series A-L for an amount of U$S 163,003,452

Series B-L for an amount of U$S 122,000,000,

METROGAS S.A.

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF JUNE 30, 2013 AND COMPARATIVES

(amounts in thousands of pesos, except where expressly stated otherwise)

and in exchange for the Company’s non-financial debt

Series A-U for an amount of U$S 16,518,450

Series B-U for an amount of U$S 13,031,550.

Also, on the same date MetroGAS exercised the power contemplated in the petition for reorganization proceedings filed by it and officially approved by the court, in order to capitalize the interest accrued on Class A Notes from January 1, 2011 to December 31, 2012, and pay in cash any interest accrued as from January 1, 2013 to the date of issuance.

As from the date of issue of the new notes, all obligations of the Company under the Existing Notes and Non-Financial Debt were terminated, and any rights, interest and benefits stipulated therein were voided and canceled. Consequently, the Existing Notes and Non-Financial Debt were extinguished and have ceased to be obligations enforceable against the Company.

Exchange under the debt restructuring was accounted for as an extinguishment of debt pursuant to the guidelines established in IFRS 9, as explained in Note 4.

The table below contains a detail of income before taxes incurred upon the restructuring of reorganization debt:

	For the six months period ended
		06.30.13

Includes Ps. 134,335 thousand of capitalized interest on Series A notes.

Principal under the new Class A Notes shall be repaid in full at maturity on December 31, 2018, in one payment. The New Notes shall bear interest at a nominal annual interest rate of 8.875%. Class B New Notes due 2018 shall bear interest solely upon the occurrence of a Triggering Event before the Deadline, and in the absence of any Triggering Event, Class B New Notes shall be automatically canceled and no debt shall be owed by the Company thereunder. Interest shall be paid on a semi-annual basis in arrears on June 30 and December 31 each year, although MetroGAS may elect to capitalize 100% of any interest accrued as from the date of issuance to June 30, 2013, and 50% of any interest accrued as from July 1, 2013 to June 30, 2014.

Pursuant to the terms and conditions of issuance of the New Notes, MetroGAS and any subsidiaries thereof shall be subject to a number of restrictions; among other things, they shall not:

METROGAS S.A.

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF JUNE 30, 2013 AND COMPARATIVES

(amounts in thousands of pesos, except where expressly stated otherwise)

Incur or guarantee any debt;

Make any restricted payments, including any payment of dividends;

Make investments of any kind;

Carry out sale and leaseback transactions;

Carry out transactions with related companies;

Also, the conditions of issuance include a mandatory Redemption provision with Excess cash.

Excess cash mean, for any calculation period of excess cash, the higher amount between the sum resulting from the calculation that starts at EBITDA, is adjusted according to the relevant terms of issue, mainly with the items that affect Company funds which are not part of EBITDA, and the balance of cash funds which, at the close of operations of the last day of such period of calculation of excess cash, are above U$S 10 million.

The above mentioned calculation period is six months, starting on April 1 or October 1 and ending on March 31 or September 30.

Available excess cash are the excess cash for the relevant calculation period minus the cash deficit at the close of operations of the last day of the period, while net available excess cash result from the available excess cash minus net capitalized interest.

The Company shall use the available excess cash to redeem pro rata any Class A Notes, and at any time after the occurrence of a Triggering Event, any outstanding Class B Notes by means of a prepayment of Notes, provided that the Company has not allocated such available amount of net excess cash to make any purchases in the market. Remaining funds after the above mentioned redemptions shall be referred to as net available excess cash.

The Company made the corresponding calculation for the first period finished on March 31, 2013, from which no excess cash resulted.

Additionally, in the ordinary course of business, and considering that MetroGAS operates the gas distribution service within the south and east area of the Great Buenos Aires, including the City of Buenos Aires, MetroGAS’ customer/supplier portfolio includes entities of the private as well as of the national, provincial and municipal sectors. As requested by NIC 24, the main transactions mentioned above include the purchase of gas from ENARSA (operations for the six-month period ended on June 30, 2013 amounted to Ps. 4,514 thousand while the net balance as at that date was Ps. 6,447 thousand).

Furthermore, as explained in Note 1.3.7 of Annex I, MetroGAS must invoice, collect and settle three specific charges, with different appropriations, which is done for the order and account of Nación Fideicomisos S.A. Balances of this operation are stated in Note 19.

Finally, as described in Note 1.3.2 of Annex I, MetroGAS signed with ENARGAS on November 21, 2012 Minutes of Agreement that establish a fixed amount per bill, separated by customer category, which has to be considered as advanced payment for future tariff adjustments provided for in the Temporary Agreement approved by Decree No. 234/09. ENARGAS executed the agreement through Resolution No. 2,407/12 published on November 29, 2012. The Minutes state that amounts thus collected shall be deposited in a specifically dedicated trust fund used for the execution of infrastructure, connections, re-boosting, extensions and/or technological adjustment of gas distribution systems. Therefore, on December 12, 2012 a trust agreement was signed by MetroGAS and Nación Fideicomisos S.A. Balances for these operations are shown in Notes 11 and 19.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

These condensed consolidated interim financial statements must be read in conjunction with Annex I included below. This Annex contains detailed additional information as required under IFRS as of December 31, 2012 and January 1, 2012, which is necessary in order to understand these condensed consolidated interim financial statements and the condensed presentation thereof pursuant to IAS 34.

1.	FINANCIAL CONDITION AND REGULATORY FRAMEWORK

As from December 2001, the Argentine Government adopted a number of measures designed to act in the face of the difficult economic, financial and social conditions prevailing in the country, which entailed a significant change in the economic policies then being applied.

The most salient of those measures included: (1) implementing a floating rate of exchange, which resulted in a significant devaluation of the Argentine peso during the first months of 2002, (ii) the conversion to Argentine pesos of some foreign-exchange denominated assets and liabilities kept within the country, and (iii) the conversion to Argentine pesos of the rates and tariffs of public services.

As part of the above measures, Public Emergency and Foreign-Exchange System Law No. 25,561 (the “Emergency Law”) was enacted on January 9, 2002. This law was subsequently supplemented by other statutes, executive decrees and regulations issued by different governmental agencies. This set of rules involved a substantial change in the terms of MetroGAS License under which the Company had been operating, and in the relationship between the Company and the Argentine Government, as it modified the tariff system established under Law No. 24,076 (the “Gas Law”) and supplementary regulations.

The Argentine Executive has been authorized to renegotiate public service agreements on the basis of the following factors: a) the impact of service rates on economic competitiveness; b) the quality of services and any investment plans contemplated in the relevant agreements; c) users’ interests and service accessibility; d) the safety of any systems involved; and e) the profitability of the companies involved. Note 1.3.2 of this annex describes the rate renegotiation process carried out between the Company and the Argentine Government.

During almost thirteen years the Company has kept its rates frozen. In the process of its License Renegotiation under Public Emergency Law No. 25,561, the Company subscribed a Temporary Agreement with the Unit for the Renegotiation and Analysis of Utility Contracts (UNIREN) on October 1, 2008, which agreement was ratified by the Argentine Executive by Executive Decree No. 234/09 published in the Official Gazette on April 14, 2009. The Temporary Agreement has not been implemented yet; due to rate schedule resulting from such Executive Decree has not been issued. Also, it has not given to MetroGAS the pass through to include in its rates any municipal contribution, tributes and other charges that have a significant, increasing and disproportionate impact on the Company’s generation of cash flow. All rate increases applied to different customer categories that the Company has been forced to include in its invoices, except for the effect of Resolution ENARGAS No. 2,407/12 described below, have not involved any revenues whatsoever, because the Company merely acts as a collection agent for funds that were used to finance a larger capacity of trunk gas pipelines, pay increased natural gas prices to producers and pay gas imports to meet domestic demand. On the other hand, this Distributor has not, during the thirteen years that its rates have remained frozen, received any subsidies from the Argentine Government.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

From 2001 to this date, the Company’s operating costs have suffered an average increase of around 521%.

On November 21, 2012, the Company, similarly to all other gas Distributors with the exception of Litoral Gas, subscribed a Memorandum (the “Memorandum”) with ENARGAS. Pursuant to the ENRG/SD/I 13,352 letter received from ENARGAS on November 29, 2012, this Memorandum is fully effective. Under this Memorandum, it was agreed that a fixed amount, which is different for different customer categories, would be established per invoice. The amounts thus received by Distributors will be deposited into a trust fund created to such an effect, and used for the performance of works relating to infrastructure, connection, power upgrades, expansion and/or technological adaptation of gas distribution network systems, safety, service reliability and network integrity, and also for maintenance and any other related expenses necessary to provide the gas distribution public service, up to the limit of the amounts effectively available to be applied within the service provision area.

Any amounts received by gas distribution License Holders will be received on account of any rate adjustments contemplated in the License renegotiation agreements subscribed in due time. In the case of MetroGAS, this is the Temporary Agreement approved by Executive Decree No. 234/09.

The Company believes that any amounts under the Temporary Agreement 2012 will be insufficient to compensate the imbalance in the financial condition of the Company, and as such they would be sufficient only to cover some expenses that would otherwise have to be financed with Company funds.

Also, in spite of the fact that the Company hired a financial advisor in order to find other options for the refinancing of its debt, the steps taken by the Company in this connection have not been successful because the proposals it received were not consistent with the Company’s actual possibilities. For this reason, the Company was unable to generate sufficient liquid funds to make payments under its financial debt which were due on June 30, 2010, and some trade payables and tax obligations.

On June 17, 2010, for the reasons detailed above, the Board of Directors decided to rely on the protection afforded under these circumstances by Argentine Law No. 24,522, and filed a petition for Reorganization Proceedings on behalf of MetroGAS (see Note 1.1 of this Annex).

On the same date, MetroGAS received notice of ENARGAS Resolution No. I-1.260, pursuant to which a receiver was appointed for the Company (as described also in Note 1.2 of the Annex attached hereto).

Finally, the above circumstances, added to increased operating costs required to maintain service quality, have affected the Company’s financial condition. The Management of the Company believes that if the conditions prevailing as of the date of these financial statements remain unchanged, its situation will continue to deteriorate, and has consequently taken a number of actions designed to mitigate the impact of its current financial condition, including:

Bring claims for rate increases (including the transfer thereto of any municipal taxes) before Argentine authorities;

Make efforts to achieve a strict cash management and expense control;

Demand additional capital contributions from Company shareholders;

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

Renegotiate payment terms with major suppliers and Trusts; and

Obtain funding from third parties.

As of December 31, 2012 the negative results shown by the Company absorbed more than 50% of its capital and reserves. Section 206 of the Argentine Companies Law prescribes a mandatory reduction of capital in the event of an occurrence of these circumstances.

1.1	Reorganization Proceedings

On account of various circumstances that significantly affected the Company’s ability to generate sufficient cash flows in order to meet its obligations as to suppliers and financial creditors, on June 17, 2010 the Board of Directors of MetroGAS filed a petition for reorganization proceedings in National Commercial Court No. 26, Clerk’s Office No. 51, file No. 056,999. A Shareholders’ Meeting of the Company held on August 2, 2010 ratified this decision of the Board of Directors.

After the different procedural steps prescribed by the Argentine Bankruptcy Law had been completed, on February 2, 2012 the Company filed a complete and final proposal for an arrangement with unsecured creditors holding allowed and provisionally admitted claims, which contemplated payment of any allowed and provisionally admitted unsecured claims by means of a delivery, in exchange for and lieu of payment of those claims, of two classes of notes (the “New Notes”) due December 31, 2018.

On May 22, 2012, the Company filed a revised proposal, including certain amendments that involved minor changes in the dates established for the occurrence of certain events (capitalization of interest and determination of Deadline, among others), and suppressed the purchase offer that the issuer was required to make upon the occurrence of a change of control.

On September 6, 2012, the acting court issued an order by which it approved the Company’s arrangement with creditors and declared terminated the reorganization proceedings under the Argentine bankruptcy law. Also, it ordered the creation of the final committee of creditors.

The debt exchange and issuance of the New Notes was implemented by the Company on January 11, 2013 with respect to unsecured creditors holding allowed and provisionally admitted claims.

The New Notes are denominated in U.S. dollars and their respective principal amounts as of the date of issue were determined as follows: (i) a Class A Note, equivalent to 53.2% of the amount of the respective allowed or provisionally admitted unsecured claim, and (ii) a Class B Note, equivalent to 46.8% of the amount of the respective allowed or provisionally admitted claim. Also, two different series were issued within each such Class of New Notes, for the purpose of identifying unsecured claims derived from previously existing notes (Series L) from any other unsecured claims (Series U). Also, the Company offered to pay, on the date of issue of the New Notes, an amount equivalent to any interest that might have accrued on such Class A New Notes referred to above as from January 1, 2011 to the date of issue, at an annual nominal interest rate of 8.875%. Pursuant to the proposal and at the Company’s option, the above interest accrued until December 31, 2012 has been capitalized. The principal of the New Notes will be repaid in full at maturity on December 31, 2018 in one payment. Class A New Notes shall be payable pursuant to its terms as from the date of issue thereof. Class B New Notes shall become payable pursuant to its terms solely as from the date when (a) the maturity of Class A New Notes is accelerated as a result of the occurrence of certain events of default provided under the principal terms and conditions of the New Notes, or (b) holders of not less than 25% of Class A, Series L New Notes have required in writing from Debtor and trustee the acceleration of maturity of Class A New Notes as a result of the occurrence of certain events of default provided under the principal terms and conditions of the New Notes (any of the events referred to under (a) or (b), a “Triggering Event”), provided such Triggering Event occurs: (i) within the first year counted as from the date of issue of the New Notes, or (ii) on or before June 30, 2014, whichever is later (the “Deadline”). In the absence of a Triggering Event occurring on or before the Deadline, then Class B New Notes shall be automatically canceled and no amount shall be owed by the Company thereunder. Any outstanding Class A New Notes shall bear interest on their principal amount at an annual nominal rate of 8.875% from the date of issue to the date of repayment of such Notes; interest shall be calculated and paid pursuant to the terms and conditions of such Class A New Notes. Class B New Notes shall bear interest solely on the principal amount of such Class B New Notes upon the occurrence of a Triggering Event before the Deadline and as from the time of such occurrence. This interest shall also accrue at an 8.875% nominal annual rate from the date of the respective Triggering Event and up to the date of repayment thereof, and be calculated and paid pursuant to the specific terms and conditions of such notes.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

On February 1 and 13, 2013, the Company filed evidence under the reorganization proceedings of its having complied with the exchange and delivery of the New Notes and the capitalization and payment of interest in order to request that the court lift any general restraining orders and issue a judicial declaration of its compliance under the reorganization proceedings pursuant to section 59 in fine of the Argentine Bankruptcy Law.

1.2	Intervention of the Company

Following the Company’s filing to commence a reorganization proceeding (concurso preventivo) on June 17, 2010, MetroGAS was notified of Resolution No. I-1,260 issued by ENARGAS, which provided for the intervention of the Company and appointed Mr. Antonio Gómez, an engineer, as interventor for the next one hundred and twenty days.

Said Resolution stated that the interventor will supervise and control all of the Company’s regular administrative and disposal activities that could have an impact in the gas distribution public service rendered by the Company, which is the core of the License. In addition, it ordered to initiate an integral corporate audit of the Company; and under said audit, to determine and appraise the value of all Company’s assets transferred by the PEN by Decree No. 2.459/92 and those added at a later date.

The intervention of MetroGAS and the appointment of Eng. Antonio Gomez have been successively extended for 120 calendar day-terms under the terms and subject to the conditions of the original ones. The last of these extensions was established by ENARGAS through Resolution No. 2,448/13 dated February 1st, 2013.

1.3	Regulatory Framework

The natural gas distribution system is regulated by the “Gas Act” which, together with Decree No. 1,738/92 issued by the Executive Power, other regulatory decrees, the specific bidding rules (“Pliego”), the Transfer Agreement and the License, establishes the Regulatory Framework for the Company’s business.

The License, the Transfer Agreement and the regulations promulgated pursuant to the Gas Act contain certain requirements regarding the quality of service, capital expenditures, restrictions on transfer and encumbrance of assets, restrictions on cross ownership among gas production, transportation and distribution companies and restrictions on transfers of common stock of MetroGAS.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

The Gas Act and the License establish ENARGAS as the regulatory entity to administer and enforce the Gas Act and the applicable regulations. ENARGAS’ jurisdiction extends to transportation, marketing, storage and distribution of natural gas. Its mandate, as stated in the Gas Act, includes the protection of consumers, the fostering of competition in the supply of and demand for gas, and the encouragement of long-term investments in the gas industry.

Tariffs for gas distribution services were established in the License and are regulated by ENARGAS.

1.3.1

Distribution License

Under the License, MetroGAS is entitled to render the public service of gas distribution for a term of 35 years. The Gas Act provides that MetroGAS may, upon expiration of the original 35-year term, apply to ENARGAS for a renewal of the License for an additional 10-year term. ENARGAS is required at that time to evaluate the Company’s performance and make a recommendation to the Executive Power. MetroGAS is entitled to such extension of its License unless ENARGAS can prove that MetroGAS is not in substantial compliance with all its obligations stated in the Gas Act and applicable regulations and decrees and the License.

At the end of the 35-year or 45-year term, as the case may be, the Gas Act requires that a new competitive bidding be held for said license, in which MetroGAS will have the option, in case it has complied with its obligations, to match the best bid offered to the Argentine Government by any third party.

As a general rule, upon termination of all periods of the License, MetroGAS will be entitled to receive the lower of the value of specified assets of MetroGAS or the proceeds paid by the successful bidder in a new competitive bidding process (Note 1.4.1 to this Annex).

MetroGAS has various obligations under the Gas Act, including the obligation to comply with all reasonable requests for service within its service area. A request for service is not considered reasonable if it would be uneconomic for a distribution company to undertake the requested extension of service. MetroGAS also has the obligation to operate and maintain its facilities in a safe manner. Such obligation may require certain investments for the replacement or improvement of facilities as set forth in the License.

The License details other obligations of MetroGAS, which include the obligation to provide distribution service, to maintain continuous service, to operate the system in a prudent manner, to maintain the distribution network, to carry out a Mandatory Investment program, to keep certain accounting records and to provide periodic reports to ENARGAS.

The License may be revoked by the Argentine Government upon the recommendation of ENARGAS under the following circumstances:

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

Serious and repeated failure by the Company to meet its obligations.

Total or partial interruption of not interruptible service for reasons attributable to the Company of duration in excess of the periods stipulated in the License within a calendar year.

Sale, disposition and transfer of the Company’s Essential Assets or encumbrances thereon without ENARGAS’ prior authorization, unless such encumbrances serve to finance extensions and improvements to the gas pipeline system.

Bankruptcy, dissolution or liquidation of the Company. Therefore, the reorganization proceeding does not affect the normal course of the operations of the Company or, consequently, is a cause of revocation of the Company’s License.

Ceasing and abandoning the provision of the licensed service, attempting to assign or unilaterally transfer the License in full or in part (without ENARGAS’ prior authorization) or giving up the License, other than as permitted therein.

Transfer of the Technical Assistance Agreement or delegation of the functions granted in said Agreement without ENARGAS’ prior authorization, during the first ten years from License granting.

The License stipulates that the Company cannot assume the debts of Gas Argentino or grant loans or encumber assets to secure debt of, or grant any other benefit to creditors of, Gas Argentino.

1.3.2

Tariff Renegotiation

The Public Emergency and Exchange Regime Reform Law No. 25,561 (“Emergency Law”) dated January 7, 2002, modified the legal framework in force for license contracts of public utilities.

The main provisions of the above mentioned Law that have an impact on the License duly granted to MetroGAS by the National Government and that modify express provisions of Law No. 24,076 (the “Gas Act”) are the following: “pesification” of tariffs that were fixed in convertible dollars at the exchange rate specified in the Convertibility Law (Law No. 23,928), the prohibition of tariff adjustments based on any foreign index, thus not allowing the application of the international index specified in the Regulatory Framework (US Producer Price Index-PPI), and the renegotiation of the License granted to the Company in 1992.

In fact, the Emergency Law established the beginning of a renegotiation process of public utility services agreements granted by the National Executive Power without detriment to the requirements that utility services companies must go on complying with all their obligations. The process began in 2002 and the Ministry of Economy and Production (“ME”) was entitled to carry out the renegotiation through the Committee for the Renegotiation of Contracts for Public Works and Services (“CRC”); said Committee was then replaced by the “Unit for the Renegotiation and Analysis of Utility Contracts” (“UNIREN”) by means of Executive Order No. 311 in 2003. The UNIREN was presided jointly by the ME and by the Ministry of Federal Planning, Public Investment and Services (“MPFIPyS”).

The Emergency Law, which was originally to be due in December 2003, was extended several times until December 31, 2013. The terms for renegotiating licenses and public services concessions were also extended.

Although MetroGAS strictly complied with the disclosure of all information required, the renegotiation process is still delayed being not possible for the Company to achieve a final agreement.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

On October 1st, 2008, MetroGAS signed a Temporary Agreement with the UNIREN which was ratified by its Shareholder’s Meeting on October 14, 2008 and approved by the National Executive Power on March 26, 2009 by Decree No. 234 (published in the Official Gazette on April 14, 2009). The mentioned Temporary Agreement establishes a Transitional Tariff Regime as from September 1st, 2008, with a readequacy of prices and tariffs including price variation of gas, transportation and distribution services. The amounts resulting from the increase actually received in distribution tariffs must be deposited by MetroGAS in a specific trust fund created to carry out infrastructure works in the License area. The Temporary Agreement has not been applied yet, due to the fact that rate schedules have not been issued.

On December 29, 2011, MetroGAS filed a complaint to interrupt the status of limitation of damages resulting from the breakdown of the economic financial equation contemplated in the gas distribution License as well as a previous administrative claim for same purposes. Said complaint was amended on February 13, 2013, and, at that time, the claimed amount was stipulated.

On November 21, 2012, the Company, as well as the other gas Distribution Companies, except for one, executed an Agreement (“Agreement”) with ENARGAS, which in accordance with ENARGAS’ letter ENRG/SD/I 13,352 received on November 29, 2012, is in full force and effect. In such Agreement a fixed amount per invoice is agreed, stating a difference by customer category. The amounts collected in respect thereof by the Distribution Companies will be deposited in a trust fund created to this effect and used to carry out infrastructure works, connection works, repowering, expansion and/or technological modification of the systems of gas distribution through network, security, reliability of the service and integrity of the network, as well as maintenance and any other related expense that may be necessary to provide the gas distribution public service, up to the amount of the funds actually available so as to be applied within the service area. On the other hand, gas distribution companies shall obtain the approval of an Execution Committee to be created in the trust fund to implement an Investment Plan of Consolidation and Expansion expressed in physical and monetary terms which guidelines shall be determined in the trust fund agreement to be entered into between the Company and Nación Fideicomisos S.A.

The amounts that gas Licensees shall receive will be taken as a payment on account of the tariff adjustments stated in the License renegotiation agreements executed from time to time, in the specific case of MetroGAS, the Temporary Agreement as approved by Decree No. 234/09. MetroGAS’ collection, as a consequence of implementing the new fixed amounts, would approximately amount to Ps. 190 million annually.

On November 29, 2012 ENARGAS Resolution No. 2,407/12 was published in the Official Gazette, specifying that MPFIPyS Resolution No. 2,000/05 had been complied with. As a consequence ENARGAS authorized Distribution Companies to collect the charge previously mentioned, stating that it should be included in the invoices in accordance with the methodology to be established by the Regulatory Authority.

The Company has been invoicing this new tariff charge since December 3, 2012, and is making the corresponding deposits in the relevant trust accounts.

On December 11, 2012 ENARGAS sent the form of a financial trust fund and private administration contract (“Trust-Fund Contract”) to be entered into by gas Distribution Companies and Nación Fideicomiso S.A. The Trust Fund Contract was executed on December 12, 2012.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

On January 16, 2013 the Operative Manual was executed with ENARGAS in accordance with the form duly sent by the regulatory authority.

The Trust Fund Contract and the Operative Manual provide the general guidelines for the management of the deposited funds. Distribution Companies will have to deposit, on a monthly basis, the amounts collected from customers together with a Sworn Statement which will be filed with ENARGAS and Nación Fideicomisos S.A. In addition, an annual Investment Plan of Consolidation and Expansion will have to be submitted to the Execution Committee for its approval. Upon obtaining approval thereof and of any modifications thereto, and once the Sworn Statement shall have been examined together with the progress of improvement works, the Execution Committee is responsible for approving the funds availability in order that Nación Fideicomisos may make the corresponding payments to suppliers for and on behalf of the Distribution Companies. Further, it is important to point out that the trust fund contract executed by MetroGAS contemplates the possibility of financing by Nación Fideicomiso S.A., provided that all those works that need financing shall have been stated in detail and approved by the Execution Committee. Such works shall be financed only with the Trust Fund Capital and only certain percentage of the collected net fixed amounts may be applied by the Distribution Company.

On February 1, 2013, MetroGAS submitted to ENARGAS the Investment Plan of Consolidation and Expansion for its approval.

1.3.3

Unbundling of Natural Gas

Due to regulatory changes that have been made to the natural gas sector since 2005, the so called “natural gas unbundling” process took place, by which the different categories of customers (except for residential customers and small commercial customers, as well as non-profit civil associations, labor unions, trade associations or mutual benefit associations, health institutions and private or public educational institutions) had to purchase natural gas volumes at the point of entry into the transportation system directly from producers and/or sellers of natural gas, leaving the regional distribution companies limited to exclusively give transportation and or distribution services of natural gas.

Additionally and in the same year, a Mechanism for Assigning Natural Gas to CNG stations was established, by which CNG stations get natural gas by means of a mechanism of periodic assignments of natural gas volumes in the Electronic Gas Market (“EGM”).

In this context, in 2005 MetroENERGÍA was created as a natural gas trading company with the aim of keeping the highest amount of customers possible and count on a proper tool in accordance with the new scenario where the Company had to perform.

MetroENERGIA was authorized by the ENARGAS to act as a natural gas trading company and or gas transportation company, and registered as agent of the EGM.

Actions taken by MetroENERGIA since its formation made it possible to retain most of the industrial and commercial customers duly contemplated in the “unbundling” process of the Company’s area, thus being able to maintain the participation of these categories of customers within MetroGAS’ sales portfolio.

(amounts in thousands of pesos, except where expressly stated otherwise)

1.3.4

Complementary Agreement with Natural Gas Producers

On October 1, 2008, SE Resolution No. 1,070/08 was published, approving the “Complementary Agreement with Natural Gas Producers” which was executed on September 19, 2008. Said Agreement was mainly aimed at restructuring gas prices at well head, segmenting natural gas residential demand, and establishing the natural gas producers’ contribution to the Trust Fund created by Law No. 26,020 to finance the sale of LPG cylinders for residential use at various prices.

In accordance with the Complementary Agreement with Natural Gas Producers, ENARGAS Resolution No. I/409/08, published on September 19, 2008, divided the “R” category of residential customers into 8 subcategories according to their natural gas consumption. Based on this subdivision, an increase on the value of natural gas at the point of entry into the transportation system was determined; however, such increase did not apply to the first three residential sub-categories and to sub-distributors.

As pursuant to the Complementary Agreement with Natural Gas Producers as approved by SE Resolution No. 1,070/08, increases in the price of natural gas had to be fairly allocated to the different components of the user’s final tariff so as to guarantee that the distributors’ equation should remain unaltered after these increases, ENARGAS made the relevant tariff adjustments and issued, in the case of the Company, Resolution No. I/446/08 by which it approved a new tariff scheme reflecting the above mentioned tariff increases effective as from September 1, 2008, (October 1, 2008, in respect of CNG increases). However, the new tariff scheme did not provide for the tariff readjustment of the distribution segment.

Additionally, on December 23, 2008, the Secretariat of Energy published Resolution No. 1,417/08 whereby, and also on the basis of the Complementary Agreement with Natural Gas Producers as approved by SE Resolution No. 1,070/08, it established new natural gas prices at the point of entry into the transportation system.

As a result, ENARGAS issued Resolution No. I/566/08, published on the same day thereof, approving the new tariff scheme to be applied which reflected such new increased prices for natural gas.

1.3.5

Procedure for Gas Applications, Confirmations and Control

On October 4, 2010, ENARGAS Resolution No. 1,410/10 was published in the Official Gazette, which approved new rules named “Procedure for Gas Applications, Confirmations and Control”, which shall be complied with by certain participants of the natural gas industry, including natural gas distribution companies, with an impact on daily natural gas nominations, transportation and distribution. As from October 1, 2010, when such Procedure became effective, MetroGAS has the total daily volume of natural gas necessary to supply its non-interruptible demand.

1.3.6

Total Energy and Gas Plus Plans

The National Government implemented the Total Energy Plan in 2007, which is aimed at guaranteeing the supply of energy resources, both liquid and gas fuels, and at encouraging the replacement of natural gas and or electricity consumption by the use of alternative fuels. As a matter of fact, Resolution No. 459/07 issued by the Ministry of Federal Planning, Public Investment and Services (“MPFIPyS”) created the above mentioned Total Energy Plan which was then ruled by different resolutions that enlarged and extended its enforcement.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

The Total Energy plan includes a propane-air provision plan under the responsibility of ENARSA. In connection with this last matter, ENARGAS Resolution No. I/831/09 was published on August 20, 2009 whereby the new specifications for synthetic natural gas to be injected into the distribution system were established. At present there is a plant injecting gas (propane-air) into MetroGAS’ distribution system operated by ENARSA. MetroGAS is responsible for controlling that all quality measures which are required by ENARGAS to ensure a safe operation are met at all times.

In addition, in 2008 the government launched, through SE Resolution No. 24/08, as amended by SE Resolutions No. 1,031/08 and No. 695/09, the so called “Gas Plus” plan to encourage production of natural gas by virtue of which every new gas volume produced under said plan shall not be considered part of the volumes included in the 2007-2011 Agreement and shall not be subject to its price conditions; however, it cannot be exported and its price has to cover associated costs and generate a reasonable profitability.

1.3.7

Trust Funds

As of the date of issuance of these financial statements, MetroGAS must invoice, collect and settle three specific charges, allocated differently. The Company carries this out on behalf of Nación Fideicomisos S.A. as fiduciary of three different trust fund contracts.

The specific charge I (ruled by Decree No. 180/04 issued by the National Executive Power, and related regulations) and the specific charge II (ruled by Law No. 26,095 and related regulations) are supported by the whole pool of users of the natural gas service other than the residential segment and are applied to the payment of infrastructure works for the expansion of the natural gas system of transportation.

In addition, specific charge III (ruled by Decree No. 2,067/08 issued by the National Executive Power, and related regulations, then included in Law No. 26,095 as stipulated by Law No. 26,784 of the National Administration Budget for 2013) is supported by the same customers that pay the foregoing charges, including in this case most of the subcategories of residential customers, and applied to the payment of the imports of additional natural gas volumes that may be necessary to meet the residential demand.

It is important to point out that none of these three specific charges invoiced and collected by MetroGAS is incorporated to the Company`s assets. On the contrary, once received, the Company is required to deposit them into the trust fund accounts designated from time to time by the Fiduciary, thus ending MetroGAS’ actions in respect thereof.

1.3.8

Municipal Taxes

The regulatory framework in force and duly applicable to the distribution of natural gas contemplates to pass through to tariffs all new taxes or levies or rate increases, applicable since the beginning of operations, on December 29, 1992, and under certain circumstances, the free use of public space for purposes of laying natural gas pipelines.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

As of the date of issuance of these financial statements the Company cannot pass through to its tariffs any payments made in respect thereof to certain municipalities in the Province of Buenos Aires and to the City of Buenos Aires (“CABA”).

The amounts paid but not recognized as a credit by MetroGAS in respect of the Study, Revision and Inspection of Works in Public Spaces Levy of the GCABA and the Right of Occupancy and Public Spaces Levy of the City of Buenos Aires, Esteban Echeverría, Almirante Brown, Ezeiza and Florencio Varela amount to Ps. 63,032 thousand and Ps. 101,259 thousand, respectively, as of December 31, 2012.

1.4.	Obligations and Restrictions Upon Privatization

1.4.1

Restricted Assets

A substantial portion of the assets transferred by “Gas del Estado” are defined in the License as “Essential Assets” for the performance of the relevant licensed service. The Company is thus obliged to identify and maintain any such Essential Assets, and any future improvements, in accordance with certain standards defined in the License.

The Company shall not, for any reason, dispose of, encumber, lease, sublease or lend any Essential Assets for purposes other than rendering the service under the License, without prior authorization of ENARGAS. Any extensions or improvements that the Company may make to the gas distribution system may only be encumbered as security for the loans due after more than one year and used to finance any such extensions or improvements.

Upon expiration of the License, MetroGAS shall transfer to the Argentine Government or its designee all Essential Assets listed in an inventory updated as of such date, free of charges and encumbrances.

As a general rule, upon expiration of the License, the Company will be entitled to collect the lesser of the following two amounts:

a) The value of the Company’s Properties, Plant and Equipment, as determined on the basis of the price paid by Gas Argentino, and the original cost of subsequent investments carried in United States Dollars and adjusted by the PPI, net of accrued depreciation.

b) The proceeds of a new competitive bidding, net of any expenses and taxes paid by the successful bidder.

1.4.2

Restrictions on the Distribution of Profits

The Company is required to keep in effect the authorization to offer the Company’s Common Stock to the public and the relevant authorization for the shares to be listed on Argentine authorized exchange markets for a minimum period of fifteen years as from the respective dates on which such authorizations were granted.

Any voluntary reduction, redemption or distribution of the Company’s equity, other than the payment of dividends, will require the prior authorization of ENARGAS.

2.	ACCOUNTING POLICIES

2.1	Basis of Preparation

2.1.1

Classification of Current and Non-Current Assets and Liabilities

The presentation of the statement of financial condition distinguishes current and non-current assets and liabilities. Current assets and liabilities are assets and liabilities expected to be recovered or canceled within the twelve months following the end of the reporting period.

Current and differed income tax assets and liabilities are presented separately and apart from other assets and liabilities.

2.1.2

Currency of Presentation

The consolidated financial statements are presented in thousands of Argentine pesos. Unless otherwise stated or required by the context, references to “amounts in pesos” or “Ps.” refer to Argentine pesos, and references to “U$S” or “U.S. dollars” refer to U.S. dollars.

2.1.3

Accounting Criteria

The consolidated financial statements have been prepared on the basis of historical cost, except for financial assets and liabilities recognized at fair value through profit or loss.

METROGAS S.A.

(amounts in thousands of pesos, except where expressly stated otherwise)

2.1.4

Cash Flows

The Company presents its cash flows from operating activities by the indirect method. Any interest paid is presented within financing activities. Any interest received is presented within investment activities.

2.1.5

Use of Estimates

Preparation of financial statements as of a specified date requires that the Company make estimates and assessments that affect the amount of recorded assets and liabilities and of contingent assets and liabilities disclosed at such date, as well as expenses and revenues for the fiscal year. Actual future results may differ from the estimates and assessments made at the date of preparation of these financial statements. More complex areas, which require professional judgment or significant assumptions and estimations, are described in Note 3.

2.2	New accounting standards and reviewed standards

As of the date of publication of these financial statements, rules and interpretations or any amendments thereto, as published by IASB and adopted by the FACPCE and the CNV, which are not yet in force because their effective date will occur later than the date of these financial statements and the application thereof by the Company, are described below:

IFRS 7 “Financial Instruments – Disclosures”

In December 2011, the IASB modified IFRS 7 “Financial Instruments – Disclosures”, which is applicable to fiscal years beginning in or ending after January 1, 2013. The amendment of IFRS 7 incorporates information disclosure requirements to assess the effect of compensation agreements, if any. The application of the amendment of IFRS 7 shall bear no impact on the Company’s operations or financial situation, but it will eventually result in additional disclosures.

IFRS 9 “Financial Instruments”

In November 2009 the IASB issued IFRS 9 “Financial Instruments”. This standard includes the first part of a three-phase project designed to replace IAS 39 “Financial instruments: Recognition and measurement”. IFRS 9 prescribes that financial assets must be classified and measured. It requires that financial assets be subsequently measured at “amortized cost” or at “fair value”, depending on the satisfaction of certain conditions. Also, IFRS 9 allows an entity to carry an instrument that would otherwise have been classified in the “at amortized cost” category, as an “at fair value” instrument if such designation eliminates or significantly reduces recognition or measurement inconsistencies.

Equity instruments must be recognized at fair value through profit or loss. However, an entity may irrevocably elect to present all changes in the fair value of any equity instruments not kept available for sale under other comprehensive income. Only dividends received from such investments are reported as profit or loss.

In October 2010, the IASB issued new guidelines under IFRS 9. These guidelines establish criteria to derecognize financial instruments and most requirements for the classification and measurement of financial liabilities currently within the scope of IAS 39. Also, they provide for the accounting of most financial liabilities at amortized cost, with a bifurcation for embedded derivatives. The remaining phases of the project, including impairment of financial instruments and hedge accounting, have not been completed yet.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

IFRS 9 and any supplements thereto will be applied retroactively for fiscal years beginning on or after January 1, 2015. Early adoption is permitted.

IFRS 10 “Consolidated Financial Statements”

On May 12, 2011, the IASB issued IFRS 10 “Consolidated Financial Statements”, which establishes principles for the presentation and preparation of consolidated financial statements when an entity has one or more other entities under its control. IFRS 10 substitutes consolidation requirements established under SIC 12 “Consolidation – Special purpose entities” and IAS 27 “Consolidated and separate financial statements”, and develops the existing principles identifying the concept of control as the determining factor to decide whether an entity should or should not be included in the controlling company’s consolidated financial statements. This standard provides an additional guide to determine control when evaluation is difficult. IFRS 10 is applicable to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

IFRS 11 “Joint Arrangements”

On May 12, 2011, the IASB issued IFRS 11 “Joint Arrangements”, which provides for a more realistic treatment of joint arrangements and focuses on the rights and duties derived therefrom and not on their legal form (as it currently does). IFRS 11 is applicable to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

IFRS 12 “Disclosure of Interests in Other Entities”

On May 12, 2011, the IASB issued IFRS 12 “Disclosure of Interests in Other Entities”. IFRS 12 is a new standard that establishes requirements for the presentation of all forms of interests held in other entities, including subsidiaries, joint arrangements, associates and non-consolidated structured entities. IFRS 12 is applicable to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

IFRS 13 “Fair Value Measurement”

In May 2011 the IASB issued IFRS 13 “Fair Value Measurement”, which is applicable to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

IFRS 13 establishes a single structure for fair value measurement when this is required under other regulations. This IFRS is applicable both to financial and non-financial elements that are measured at fair value.

Fair value is measured as the price that would be received to sell an asset or paid to transfer a liability in an ordinary arm’s-length transaction at the measurement date.

IAS 27 (revised) “Separate Financial Statements”

On May 12, 2011, the IASB issued IAS 27 (revised). The revised standard introduces changes into separate financial statements which arise from the inclusion of modified control criteria under new IAS 10. These changes are applicable to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

(amounts in thousands of pesos, except where expressly stated otherwise)

IAS 28 (revised) “Investments in Associates and Joint Ventures”

On May 12, 2011, the IASB issued IAS 28 (revised). The revised standard includes the requirement that joint ventures, as well as associates, must be accounted for using the equity method after the issuance of IFRS 11. The revised standard is applicable to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

Modifications to IFRS 1: “First-Time Adoption of International Financial Reporting Standards”

On May 17, 2012 the IASB issued a modification of IFRS 1 “First-Time Adoption of International Financial Reporting Standards” as part of its 2009-2001 annual improvement cycle. This amendment makes it clear that an entity may opt for the adoption of IAS 23 “Borrowing Costs” whether as from the transition date or from an earlier date. As from the date when IAS 23 is adopted by an entity, interest costs under the Argentine GAAP will not be reclassified. The amendment will apply to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

IAS 19 “Employee Benefits”

In June 2011, the IASB issued IAS 19 “Employee Benefits”, applicable to fiscal years beginning on or after January 1, 2013. Early adoption is permitted.

The amendment to IAS 19 eliminates the option to differ the recognition of actuarial profits and losses in the measurement of defined benefit plans, which implies that all such differences will be recognized under Other Comprehensive income. The application of this amendment will not have any impact on the results of the Company.

IAS 1 “Presentation of Financial Statements”

In June 2011, the IASB modified IAS 1 “Presentation of Financial Statements”, applicable to fiscal years beginning on or after July 1, 2012. Early adoption is permitted.

Modified IAS 1 improves the presentation of items included in the Statement of Comprehensive income, classifying them by nature and categorizing them into items that upon the satisfaction of the required conditions will be reclassified into the Statement of Comprehensive income for subsequent periods and those that will not be so reclassified.

IAS 32 “Financial Instruments: Presentation”

In December 2011 the IASB amended IAS 32 “Financial Instruments: Presentation”; this modification is applicable to fiscal years beginning on or after January 1, 2014. Earlier adoption is authorized. The amended IAS 32 provides guidance on matters relating to the offsetting of financial assets and liabilities.

The adoption of rules and interpretations or amendments to the rules mentioned in previous paragraphs has had no significant impact on the Company’s financial statements.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

In addition to IFRS 9 “Financial Statements”, IFRS 10 “Consolidated Financial Statements”, IFRS 11 “Joint Agreements” and IFRS 12 “Statement of interests in other companies”, which have been applied in advance since the transition date, the Company has not chosen to apply in advance any other rule or interpretation allowed by IASB.

2.3	Segment Reporting

Segment reporting is presented on a consistent basis with internal information provided to the Chief Operating Decision Maker (CODM). The CODM is responsible for the allocation of resources and establishing the performance of the entity’s operating segments, and has been identified as the body that implements the Company’s strategic decisions.

The Company examines operating segments on a consolidated basis, and therefore provides information thereon in Note 7 to the consolidated financial statements and Note 7 of this Annex.

2.4	Foreign Currency Conversion

2.4.1

Functional Currency and Currency of Presentation

The items included in the Company’s financial statements are measured in the currency of the major economic environment where the entity operates (the “functional currency”), which is the Argentine peso, according to the criterion established IFRS 21. The consolidated financial statements are presented in thousands of Argentine pesos, which is the Company’s currency of presentation.

2.4.2

Foreign-Currency Denominated Transactions and Balances

Transactions in foreign currencies are translated into the functional currency at the rates of exchange prevailing on their respective dates. Any profits and losses from exchange differences derived from each transaction and upon the conversion of foreign-currency denominated monetary assets and liabilities at the end of the fiscal year are recognized as income for the fiscal year.

2.5	Revenue Recognition

Revenues are recognized at fair value of the consideration received or to be received, taking into account the estimated amount of any discounts, bonuses or commercial rebates that may be granted by the Company.

The Company recognizes sales revenues on the basis of gas delivered or liquid and its transportation and distribution, if applicable, to customers, including any estimates of gas amounts delivered but not billed yet at the end of each fiscal year or period. Revenues related to the tariff increases established under Resolution No. 2,407/12 as explained in Note 1.3.2 are recognized at the time they are accrued for billing to customers.

Effectively delivered amounts have been determined on the basis of purchased gas volumes and other data.

Also, MetroGAS, through its subsidiary MetroENERGÍA S.A., acts in certain transactions as a natural gas marketing agent on behalf and for the account of producers and/or third parties and receives a fee that is recognized as a revenue in the consolidated income statement.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

2.6	Properties, Plant and Equipment

As of the transition date, the Company has elected to consider the cost of Properties, plant and equipment as an deemed cost, which is restated in constant currency in accordance with the method used before the adoption of IFRS (Argentine GAAP).

The cost of Properties, plant and equipment balances includes the following:

In respect of assets received at the time the License was granted, the overall transfer value as defined in the Contract of Transfer has been taken for Argentine GAAP purposes as the original value of fixed assets, which arises as the counterpart of any contributions made and any restated transferred liability.

On the basis of a special work conducted by independent experts in 1993, the overall original value referred to in the preceding paragraph has been allocated to the different asset categories included therein, assigning them a useful life equivalent to the remaining years of service as estimated by the Company based on the type of asset, state of repair and any renewal and maintenance plans related thereto.

Any assets acquired after the date when the License was granted have been valued at their purchase cost, except in the case of distribution networks built by third parties (various associations and cooperatives), which were valued, at amounts equivalent to a specified number of cubic meters of gas decided by the ENARGAS determined to compensate to those third parties.

Any subsequent costs (larger maintenance works and reconstruction costs) are included in the value of assets or recognized as a separate asset, as the case may be, only if there is a probability that any future benefits associated with the respective assets will flow to the Company, and the costs involved may be reliably measured and the condition of assets will be improved by the investment with respect to its original condition. Any other maintenance and repair expenses are recognized as income for the fiscal year in which they are incurred.

Any work in progress is valued based on the degree of progress. Works in progress are shown at cost minus any loss from impairment, if applicable. Costs include any expenses attributable to construction, including the cost of any loans capitalized under IFRS, where such expenses are part of the cost incurred for purposes of purchasing, building or producing a piece of Properties, plant and equipment that requires of necessity a considerable period of time until being fit for use. Financial costs cease to be capitalized when the respective asset is substantially completed or suspended, in case the development thereof is in this latter condition. Any costs attributable to activities conducted for the planning, execution and control of investments in Properties, plant and equipment are charged to assets by the Company. Depreciation of these assets begins when they are economically fit for use.

As explained in Note 1.3.1 of this annex, a substantial portion of the assets transferred by Gas del Estado have been defined under the License as “Essential Assets” for the provision of the licensed service and are subject to restrictions and limitations.

Depreciation, based on a principle involving components, is calculated on a straight line basis during the useful life of assets, as detailed below for the major components of Properties, Plant and Equipment:

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

		Estimated useful life
·	Medium and low pressure ducts and networks	42-50
·	High pressure branch lines	45
·	Pressure regulation and measurement stations	25
·	Facilities for consumption measurement	20
·	Other technical facilities	15
·	Information and telecommunications systems	5
·	Buildings and civil constructions	50
·	Machinery, equipment and tools	5-15
·	Vehicles	5-10
·	Furniture and fixtures	10

Land is not subject to depreciation. The residual value and useful life of assets are reviewed and adjusted if applicable, not less frequently that at the end of each fiscal year.

Income from sales of Properties, plant and equipment are accounted for when any significant risks and benefits have been transferred to the purchaser. Income from sales is determined by a comparison of any amounts received, net of direct selling expenses, and the carrying value of the asset, and is recognized under other operating expenses and income in the consolidated statement of comprehensive income.

The Company examines the recoverability of its long term assets annually or upon the occurrence of events or changes in circumstances that may be a possible indication of impairment of those assets with respect to their recoverable value, which is measured as use value at the end of the fiscal year.

Use value is determined on the basis of projected and discounted cash flows with the use of discount rates that reflect the time value of money and any specific risks involved in the assets under consideration.

Cash flows are prepared on the basis of estimates of the future behavior of certain sensitive variables for the determination of recoverable value, including: (i) nature, opportunity and form of tariff increases and recognition of cost adjustments; (ii) projected gas demand; (iii) evolution of costs to be incurred; and (iv) macroeconomic variables such as growth rates, inflation rates, exchange rates, among others.

When the carrying amount of an asset is higher than its estimated recoverable value, the carrying amount thereof is reduced to its recoverable value as described in Note 2.9 to this annex.

Notwithstanding the current economic and financial condition described in Note 1 of this annex, the Company has prepared its projections in the understanding that it will be granted tariff improvements adapted to the prevailing circumstances. The Company, however, is not able to give any assurance that the future behavior of the premises it used to prepare its projections will be in line with its estimates, and consequently those premises may differ significantly from any estimates and assessments made as of the date of preparation of these consolidated financial statements. See Note 3 – Key accounting estimates and judgments in this Annex.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

2.7	Investment Properties

Investment Properties includes certain properties that the Company keeps in order to obtain revenues from long-term rent and also from the appreciation thereof, and which are not currently occupied by the Company for its own operations.

The Company has adopted the cost method for all its investment properties. Therefore, investment properties is recorded at cost, less accumulated depreciation and impairment, if any.

Under the cost method, an investment properties is impaired if its book value exceeds its recoverable value. When the individual components of investment properties have different useful lives, they are separately accounted for and depreciated. Any costs incurred subsequent to initial recognition are included into the carrying amount of the relevant asset or recognized as a separate asset, as it may correspond, only if there is a probability that such costs will generate an economic benefit for the Company in the future and such benefit can be reliably measured. These costs may include the cost of improvement or of replacement of parts which meet capitalization requirements. The carrying amount of any replaced part is derecognized.

Investment property is recorded at cost less any accumulated depreciation and any accumulated impairment loss.

2.8	Impairment test of non-current assets

The Company reviews the book value of its property, plant and equipment and investment properties at the closing date of each fiscal year in order to determine whether there is any indication that such assets may not be recoverable.

The impairment policy for non-current assets is described in Note 3 Key accounting estimates, in this annex.

2.9	Financial Assets

The Company has adopted IFRS 9 as from the transition date, since this accounting principle provides for relevant disclosures of more reliable information so that users may evaluate figures, time and uncertainty of future cash flows.

2.9.1

Classification

The Company classifies financial assets into the following categories: assets which are measured at their fair value and assets which are measured at their amortized cost. This classification depends on whether the financial asset is an investment in a debt or an equity instrument. In order for a financial asset to be measured at amortized cost, the two criteria described below must be met; otherwise financial assets are measured at fair value. IFRS 9 requires that all investments in equity instruments be measured at fair value.

a)	Financial assets at amortized cost

Financial assets are measured at amortized cost if the following conditions are met:

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

the objective of the Company’s business model is to hold the assets to collect the related contractual cash flows; and

ii)

the contractual terms give rise, on specified dates, to cash flows that are solely payments of principal and interest on its outstanding amount.

As of December 31, 2012 and January 1, 2012, the Company’s financial assets measured at their amortized cost are cash and cash equivalents, trade receivables and other receivables.

b)	Financial assets at fair value

If either of the two criteria mentioned above is not met, financial assets are measured at fair value through profit or loss.

As of December 31, 2012 and January 1, 2012, the Company’s financial assets measured at their fair value through profit or loss are mainly mutual funds.

2.9.2

Recognition and Measurement

The regular purchase or sale of financial assets is recognized on the trade date, i.e. the date on which the Company agrees to acquire or sell the asset. Financial assets are derecognized when the rights to receive the cash flows from the investments have expired or been transferred and the Company has transferred substantially all the risks and rewards of the ownership of the assets.

Financial assets are initially recognized at their fair value plus, in the case of financial assets not measured at fair value through profit or loss, transaction costs that are directly attributable to the acquisition thereof.

2.9.3

Impairment of Financial Assets

At the end of each year, the Company assesses whether there is objective evidence that the value of a financial asset or group of financial assets measured at amortized cost is impaired. The value of a financial asset or group of financial assets is impaired, and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a “loss event”), and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated.

Impairment tests may include evidence that the debtors or group of debtors are undergoing significant financial difficulties, have defaulted on interest or principal payments or made them after they had come due, the probability that they will enter bankruptcy or other financial reorganization, and when observable data indicate that there is a measurable decrease in the estimated future cash flows, such as changes in payment terms or in the economic conditions that correlate with defaults.

The amount of the impairment loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The asset’s carrying amount is reduced and the amount of the impairment loss is recognized in the consolidated statement of net comprehensive income. As a practical suggestion, the Company may measure the impairment on the basis of the fair value of an instrument using an observable market price. If in a subsequent period the amount of the impairment loss decreases, and such decrease is objectively related to an event occurring after impairment recognition (such as, for example, an upgrade of the debtor’s credit rating) the previously recognized impairment loss is reversed to the extent of the decrease in the consolidated statement of net comprehensive income.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

2.9.4

Offsetting of Financial Instruments

Financial assets and liabilities are offset, and the net amount reported in the balance sheet, when there is a legally enforceable right to offset the recognized amounts, and there is an intention to settle on a net basis, or realize the asset and settle the liability simultaneously.

2.10	Trade Receivables and Other Receivables

Trade receivables

Any receivables arising from services billed to customers but not collected as well as those arising from services rendered but unbilled at the closing date of each financial year are recognized at fair value and subsequently measured at amortized cost using the effective interest rate method less any impairment. Interest income is recognized applying the effective interest rate, except for such accounts receivable in a short term in case that recognition of the interest is not substantial.

Trade receivables include any services rendered but unbilled at the end of the financial year.

The so called “PURE” receivables correspond to the Gas Rational Use Program, which is a program whereby consumers are encouraged to use less energy by receiving benefits and or penalties in case they exceed a certain level of consumption. Any credit balance in Trade and other receivables correspond to compensations net of additional charges due to excess consumption to be billed.

Trade receivables are recorded net of the allowance for doubtful accounts, which is based on a recoverability analysis made by the Company.

Other receivables

Other receivables are initially recognized at fair value (generally the original billing/settlement amount) and subsequently measured at amortized cost, using the effective interest rate method, and when significant, adjusted by the time value of the money. The Company records a provision for impairment when there is objective evidence that the Company will not be able to collect all the amounts owed to it in accordance with the original terms of the receivables.

2.11	Cash and Cash Equivalents

In the consolidated statement of cash flows, cash and cash equivalents include cash on hand, demand deposits with banks and other short-term highly liquid investments with original maturities of three months or less as from their date of acquisition.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

2.12	Trade Payables and Other Accounts Payable

Trade payables

Trade payables are payment obligations with suppliers for the purchase of goods and services in the ordinary course of business. Trade payables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest rate method.

The line items “Trust Funds” and “Trust Funds Decree No. 2,407” within this account include collected amounts which deposit was pending at the end of each year corresponding to any charges under Note 1.3.7. and 1.3.2 of this annex, respectively.

Other accounts payable

The other liabilities are initially recognized at fair value and subsequently measured at amortized cost using the effective interest rate method.

2.13	Financial Debts

Financial debts are initially recognized at fair value, net of costs incurred in the transaction. Subsequently, they are measured at amortized cost. Any difference between the funds obtained (net of direct costs incurred in the transaction) and the amount to be paid at maturity is recognized in profit or loss during the term of the borrowings using the effective interest rate method.

2.14	Borrowing Costs

Borrowing costs attributable to the acquisition, construction or production of qualifying assets, which are those assets that take a substantial period of time to get ready for their intended use or sale, are capitalized as part of the cost of such assets until such time as they are in condition to be used or sold.

All other borrowing costs are recognized as an expense in the period in which they are incurred.

2.15	Income Tax and Minimum Presumed Income Tax

The income tax expense for the year is comprised of the current tax and the deferred tax. Income tax is recognized in the statement of comprehensive income, except to the extent that the tax relates to items recognized in other comprehensive income or directly in equity, in which case, the income tax is also recognized in other comprehensive income or directly in equity, respectively.

The current income tax charge is calculated on the basis of the tax laws in effect or which are substantially approved as of the end of each year. The Company records provisions on the basis of the amount expected to be paid to tax authorities.

Income tax is recognized applying the deferred tax method, on the temporary differences arising between the tax base of assets and liabilities and their carrying amounts. The deferred tax is determined using the tax rate in effect or substantially approved at the end of each year, and is expected to apply when the deferred tax assets are realized or the deferred tax liabilities are settled.

Deferred tax assets are recorded when the existence of future taxable income against which temporary differences may be offset is possible.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

A deferred tax is determined on temporary differences arising from investments in subsidiaries, except where the Company is able to control the timing of the reversal of the temporary differences and it is probable that the reversal will not occur in the foreseeable future.

Argentine entities are subject to Minimum Presumed Income Tax (“MPIT”). Pursuant to tax laws currently in effect, an entity is required to pay the higher of the income tax or the MPIT. The Company creates a provision for MPIT for each individual entity by applying the current rate of 1% and based on each company’s taxable assets at year-end, as defined under Argentine laws. Should the MPIT exceed the income tax, such excess may be computed as a payment on account of any future income tax payable during a period of 10 years. When the Company believes that it is possible that the MPIT charge will be used as an advance payment of the income tax obligation, the Company records the MPIT as a current or noncurrent receivable, as applicable, under Advance payments in the balance sheet, otherwise it charges the MPIT to profit or loss under “Income tax” in the statement of comprehensive income.

2.16	Salaries and Social Security

Severance payments are made upon termination of employer-employee relationship by decision of the employer before the corresponding retirement date, or upon an employee voluntarily accepting his retirement in change of a compensation payment. The Company recognizes severance payments when it undertakes to terminate the labor relationship by creating a formal program without retirement, or to pay compensation as part of a proposal aimed at encouraging voluntary retirements.

Bonus granted to employees are recorded as a liability and expense due to bonus payments under the terms and according to the standards set forth by the Company for certain managers and officers. A provision is created when the Company is required under the contract or when past practices reflect that the Company is impliedly required to act accordingly.

The Company has no specific contribution plans and does not make any payment based on shares.

2.17	Reorganization Liabilities

The reorganization liabilities include any liabilities subject to the reorganization proceeding filed by the Company on June 17, 2012, as detailed under Note 1.1 of this Annex. Liabilities were valued at their nominal value incorporating, when applicable, financial interest accrued until the date of filing of the reorganization proceeding, on which, according to Article 19 of the Argentine Bankruptcy Law, interest ceased to accrue.

Since the judicial approval of the reorganization proposal, the reorganization debt includes all outstanding verified and admissible debts owed to unsecured and secured creditors.

2.18	Provisions

Provisions are recognized when the Company in respect of a present obligation undertaken by it, whether legal or constructive, arising as a result of a past event, believes that an outflow of resources will be necessary to pay it, and when a reliable estimation can be made in respect thereof.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

The amount recognized as provision is the best estimate of the expenditure required to settle the present obligation, at the end of the reporting period, taking into account the corresponding risks and uncertainties. When a provision is measured using the estimated cash flow to settle the present obligation, the carrying amount represents the present value of such cash flow. This present value is obtained by applying a pre-tax discount rate that reflects market conditions, the time value of money and the specific risks of the obligation.

Provisions have been created and included in liabilities in order to face any contingency which could originate future payment obligations. To estimate their amount and the likelihood of an outflow of resources, the opinion of the Company’s legal advisors has been taken into account.

2.19

Leases

An agreement is or includes a lease depending on the nature of the agreement at the time of its execution, if performance thereof depends on the use of one or more specific assets or if the agreement assigns the right to use the asset.

Those leases in which a significant portion of the risks and benefits deriving from ownership are kept by lessor are classified as operating leases. As of December 31, 2012, the Company has only lease agreements that are classified as operating leases.

As lessee

Operating lease payments are recognized as operating expenses in the statement of comprehensive income on a straight-line basis throughout the term of the lease.

As lessor

Those leases in which the Company does not transfer substantially all the risks and benefits inherent to the ownership of the asset are classified as operating leases.

Operating lease collections are recognized as income in the statement of comprehensive income on a straight-line basis throughout the term of the lease.

2.20	Balances with Related Parties

Receivables and liabilities with related parties are initially recognized at fair value and subsequently measured at amortized cost in accordance with the terms agreed upon by the parties involved.

2.21	Shareholders’ Equity

Items included in shareholders’ equity are valued pursuant to accounting principles in effect on the transition date. Changes in shareholders’ equity have been recorded in accordance with shareholders’ resolutions and legal rules and regulations, and even when any such items would have reflected a difference balance in case IFRS had been applied in the past.

Capital stock and adjustment to capital stock

Capital stock is composed of contributions made by shareholders and represented by shares, and comprises outstanding shares at their par value. Capital stock has been recorded at its nominal value and any adjustment arising from monetary restatements made in accordance with Argentine GAAP on the transition date to the IFRS is recorded under Adjustment to capital stock.

In accordance with Argentine GAAP in force before the implementation of the IFRS, equity items were restated to reflect the effects of changes in currency purchasing power until March 1st, 2003, following the restatement method set forth by Technical Resolution No. 6 issued by the Argentine Federation of Professional Councils in Economic Sciences. As from such date on, and in compliance with Decree No. 664/03 issued by the Argentine Executive Power, the Company discontinued the preparation of financial statements in constant currency.

Legal reserve

In accordance with the provisions of the Argentine Companies Law No. 19,550, the Company has to appropriate to the legal reserve no less than 5% of the sum of net income for the year, prior year adjustments, transfers from other comprehensive income to retained earnings and accumulated losses from previous years, until such reserve reaches 20% of the Capital Stock plus Adjustments to capital stock. As of December 31, 2012 and January 1st, 2012, the legal reserve is fully funded.

2.22	Earnings (Losses) Per Share

Basic earnings (losses) per share are calculated by dividing the gain attributable to the controlling interest of the equity instruments of the company, by the weighted average number of common shares outstanding during the period, excluding treasury stock purchased by the Company.

As of the date of issuance of these consolidated financial statements, MetroGAS has not issued equity instruments which give rise to potential common shares. As a result, the calculation of diluted net loss per share coincides with the calculation of the basic net earnings (loss) per share.

3.	KEY ACCOUNTING ESTIMATES AND JUDGMENTS

Significant accounting policies of the Company are described in Note 2. Not all significant accounting policies require that the Company applies subjective criteria or complex estimates. The following section provides an understanding of the policies that the Company considers critical given their degree of complexity or the criteria or estimates involved in their application and their impact on the consolidated financial statements. Those criteria include forward-looking assumptions or estimates. Actual results may differ from these estimates.

For a better understanding of the manner in which the Company forms its judgments about future events, including the variables and assumptions underlying the estimates, and how sensitive those judgments are in respect of different variables and conditions, comments have been included in relation to each critical accounting policy described below:

Impairment of properties, plant and equipment;

Recognition of revenues and trade receivables;

Provisions;

Deferred income tax and minimum presumed income tax;

Application of IFRIC 12 “Service Concession Arrangements”.

3.1	Impairment of properties, plant and equipment

The Company reviews the book value of its properties, plant and equipment as of the date of closing of each fiscal year in order to detect any indication that such assets may not be recoverable. Also, the Company assesses the book value of its long term assets based on the recovery value thereof from time to time, when any events or change of circumstances indicate that the carrying value of an asset is not recoverable. Indications of impairment to be observed in this analysis include, among others, any existing physical damage to or significant changes in the use of assets, deterioration in the expected level of asset performance or a significant drop in revenues. When an asset ceases to generate cash flows independently from other assets, the Company estimates the recoverable amount of the cash generating unit that the asset belongs to. Given the nature of the Company’s business and the assets that form the infrastructure for the provision of the public service involved in natural gas distribution, a substantial portion of the Company’s individual assets do not generate independent cash flows and consequently MetroGAS believes that the assets included in properties, plant and equipment are one cash generating unit (CGU).

If the recoverable amount of the assets of this CGU is exceeded by their carrying amount, the carrying amount of the respective asset or CGU is reduced to its recoverable amount. Impairment losses are immediately recognized in the statement of comprehensive income.

The recoverable amount is determined on the basis of projected and discounted cash flows, applying discount rates that reflect the time value of money and the specific risks involved in the assets under analysis.

The Company believes that its accounting policy in relation to long term asset impairment is a “critical accounting policy” for the reasons set forth below:

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

The current economic and financial condition of MetroGAS, referred to in Note 1 of this annex, given the current situation about tariffs and cost increases, is highly likely to experience changes from one period to the next as it requires MetroGAS to make certain estimates and assumptions (such as future revenues and cost of revenues) to determine their recoverable amount; and

A recognition or reversion of an impairment or recoverable amount has a significant impact on the assets disclosed in the Company’s consolidated financial statements and results of operations. Estimated future revenues require that the Company form essential judgments, as actual revenues have experienced in the past and are expected to continue experiencing fluctuations, in particular due to the currently pending rate renegotiation process.

3.1.1

Impairment test for the fiscal year ended on December 31, 2012

The Company has identified indicators of impairment and conducted an impairment test on its properties, plant and equipment for the fiscal year ended on December 31, 2012, in accordance with IFRS. On the basis of such test, the carrying amount of properties, plant and equipment items was compared with the current value of the future cash flow to be generated by such assets. This estimation was made using a probability approach. As the estimation of the discounted future cash flow exceeds the carrying amount of such assets, the Company determined that they had not suffered an impairment.

With respect to material estimates used for the conduct of the above tests, and taking into account (i) the nature, opportunity and extension of the rate renegotiation process with the Argentine Government, (ii) the erosion of operating profits resulting from increased operating costs, (iii) an analysis of how current results compare to projections for former periods, (iv) the experience of Gas Natural Fenosa, another gas distribution company acting in the Buenos Aires metropolitan area (the major gas market in Argentina), whose renegotiation agreement was approved by the Argentine Executive on April 10, 2006 (and consequently implemented by ENARGAS on April 9, 2007 and October 10, 2008), and has now begun a review of its overall tariff, and (v) the status of current negotiations between MetroGAS and the Argentine Government, three different scenarios have been contemplated using a probability approach pursuant to which the probable occurrence of each of them was examined. As described below, different assumptions were adopted for each scenario and then a probability of occurrence was assigned to each projected cash flow based on current objective information. In addition, all cash flow projections have been prepared bearing in mind the remaining term of the License, without considering any extension, which does not exceed the residual useful life of Properties, plant and equipment.

The most relevant premises adopted for the preparation of estimated cash flows by the Company are described below:

Rate increases: projections were made by the Company based on an assumption of gradual rate increases from 2013 to 2018 up to rates significantly higher than current peso denominated rates.

ii.

Inflation rate: stable levels have been assumed, consistent with the levels observed at the end of the fiscal year.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

iii.

Exchange rate: a 10% depreciation of the Argentine peso with respect to the U.S. dollars has been assumed.

Significant estimates concerning the different scenarios in relation to cash flows and the probability of occurrence of each of them are summarized below:

Basic scenario: For this cash flow it was assumed that rate levels similar to those currently applied by Gas Natural Fenosa will be reached, and then gradually increased so that the Company’s average historical tariffs will be reached. This cash flow scenario has been assigned a probability of occurrence of 66.5%.

Pessimistic scenario: For this cash flow it was assumed that rate levels only similar to those currently applied by Gas Natural Fenosa will be reached, followed by an integral tariff revision. This cash flow scenario has been assigned a probability of occurrence of 10.0%.

Optimistic scenario: For this cash flow it was assumed that rate levels will have been gradually achieved by 2018, and that those levels will bear to regional tariffs in South America, specially Brazil and Chile, the same proportion as in 2001. This cash flow scenario has been assigned a probability of occurrence of 23.5%.

The probability of occurrence of each cash flow scenario is based on: (a) the recent experience of Gas Natural Fenosa, another gas distribution company acting in the Buenos Aires metropolitan area (the major gas market in Argentina); as mentioned above, this company not only subscribed a renegotiation agreement with the Argentine Government but also had its new tariff approved by ENARGAS, and is now able to bill its distribution services under the new rates; (b) the current regulatory framework, including the Gas Law and above mentioned regulations on gas rates; (c) recent ENARGAS Resolution No. 2,407/12, which established a new charge representing a rate increase of around 54% as from December 2012; and (d) renegotiation agreements signed by all other gas distribution companies, with the exception of the Company and another gas distributor; these agreements enable the parties thereto to begin a full tariff review and establish (i) a semi-annual tariff review in order to adjust rates to the general cost variation index when this index varies by more than 5%, and (ii) a five-year review similar to the five-year review originally established in MetroGAS license.

The impairment test conducted at transition date January 1, 2012, assumed premises similar to those described above, except for the bankruptcy scenario that it contemplated. As of December 31, 2012 that bankruptcy scenario has not been considered on account of the following reasons: (a) approval by creditors of the reorganization proposal under the Company’s reorganization proceedings; (b) approval by the court of the arrangement made with creditors; (c) beginning of an effective rate increase based on ENARGAS Resolution No. 2,407/12 referred to above; and (d) an agreement with YPF for the purchase of Gas Argentino S.A. shares owned by BG; as of December 31, 2012 this company was the controlling shareholder and held a 70% interest.

3.2	Revenue recognition and trade receivables

Revenues are recognized on an accrual basis upon delivery to customers. This includes estimates of delivered gas or liquids amounts not yet billed at the end of each fiscal year, its transportation and distribution, if applicable. Amounts effectively delivered are estimated on the basis of purchased volumes and other historical data. Revenues related to the tariff increases established under Resolution No. 2407/12 as explained en Note 1.3.2 are recognized at the time they are accrued for billing to customers.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

The Company is exposed to bad debt losses. The allowance for doubtful accounts is created on the basis of estimated payments received by the Company. While the Company uses available information to make such estimations, these provisions may possibly have to be adjusted in the future if future economic conditions differ substantially from the assumptions used in their preparation. The relevant charge is shown under selling expenses; no adjustments are made to trade receivables. In order to estimate the allowance for doubtful accounts, the Company permanently assesses the amount and nature of any trade receivables, including the age thereof and users’ financial condition.

3.3	Provisions

The Company has certain contingent liabilities in relation to actual or threatened claims, lawsuits and other proceedings. A liability is accrued by MetroGAS when future costs are likely to be incurred and they may be reasonably estimated. Such accrual is based on MetroGAS estimates made according to available information and on the opinion of legal counsel.

3.4	Deferred income tax and minimum presumed income tax

The Company establishes the accounting charge for the income tax according to the deferred tax method, which considers the effect of temporary differences resulting from the various bases for measuring assets and liabilities under accounting and tax criteria and the tax loss carried forward and unused tax credits which may be deducted from future tax gains, computed at the current tax rate, which at present amounts to 35%.

In addition, the Company determines the Minimum Presumed Income Tax (MPIT) by applying the current rate of 1% of assets to be considered at the close of every fiscal year. This tax is complementary of the income tax obligation. This tax is determined by application of an effective 1% rate on the tax basis of certain assets. The final amount to be paid will be the higher of income tax or minimum presumed income tax. However, if minimum presumed income tax is higher than income tax for any fiscal year, the excess amount may be computed as a payment on account of any excess income tax over minimum presumed income tax that may arise for any of the ten subsequent fiscal years.

The Company evaluates the recoverability of deferred income tax and MPIT taking into account the probability that some or all deferred tax assets or claims may not be realized. For purposes of this evaluation, the Company considers the scheduled reversion of deferred income tax liabilities, projected future tax profits, tax planning strategies and any objective evidence of recovery.

3.5	Application of IFRIC 12 “Service Concession Arrangements”

Interpretation No. 12 “Service Concession Arrangements” (IFRIC 12) establishes some accounting guidelines for private entities that provide public services under a service concession agreement or similar arrangement. IFRIC 12 is applicable to license holders depending, among other things, on the extent to which the grantor controls or regulates the services and any significant residual interest in the assets at the end of the term of the arrangement.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

Considering that IFRIC 12 establishes general guidelines and principles, judgment is required to determine whether it is applicable due to the specific nature of each service concession or license and the complexity inherent in the different notions included in its interpretation.

The Company has examined the nature and terms and conditions currently in effect under its natural gas distribution License and the guidelines established by IFRIC 12. On the basis of such analysis, the Company concluded that its license is outside the scope of IFRIC 12, primarily because of the features of its license renewal, which give a result similar to the possible outcome of a perpetual right for the operation of infrastructure. In this same respect and coincidentally, the CNV issued Resolution No. 613 on December 20, 2012, which sets forth the reasons and grounds on which in its opinion natural gas transportation and distribution services concession holders and their controlling entities are not within the scope of IFRIC 12.

4.	FINANCIAL RISK MANAGEMENT

4.1	Financial Risk Factors

The Company has in place several financial risk management policies that enable it to mitigate its exposure to the market risks involved in its business activity (including risks associated to fluctuations in exchange rates, interest rates and the price of the products sold by it), credit risk and liquidity risk.

4.1.1

Market Risk

a)	Exchange Risk

The Company is primarily exposed to fluctuations in U.S. dollar (U$S) – Argentine peso (Ps.) rate of exchange.

In accordance with the Public Emergency Law, enacted in January 2002, the rates charged by the Company for its natural gas distribution services have been translated to Argentine pesos at a rate of Ps. 1.00 = U$S 1.00, although the peso has been devalued with respect to the U.S. dollar. Most Company revenues are denominated in pesos.

On the other hand, the Company’s U.S. dollar denominated financial debt amounted to U$S 260,733 thousand as of December 31, 2012, and to a nominal U$S 314,553 thousand nominal amount after restructuring.

As of December 31, 2012, the Company’s net monetary liabilities amounted to U$S 255,230 thousand. The Company estimates that after restructuring and considering the accounting value of debts, each 10% increase or decrease of the Argentine peso – U.S. dollar exchange rate would give rise to a Ps. 75 million loss or profit before taxes. This is a hypothetical sensitivity analysis, as the real impact of such fluctuations might differ significantly and change in the course of time.

b)	Interest Rate Risk

MetroGAS has a limited exposure to risks associated with interest rate fluctuations, because 100% of its financial indebtedness bears interest at a fixed rate.

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

On the other hand, the Company seeks to conduct financial transactions with top-level entities; these transactions include demand deposits and mutual fund investments. As of December 31, 2012, current investments in mutual funds and interest-bearing checking accounts amounted to Ps. 110,427 thousand. Such placements of funds bear interest at variable rates.

c)	Price Risk

The Company is not exposed to a commodity price risk in its gas distribution segment because the rates currently charged by MetroGAS to its customers are subject to regulation, and the regulatory framework contemplates a mechanism for the transfer of gas purchase costs to rates.

4.1.2

Credit Risk

Credit risk is the risk that a counterparty will default on its contractual obligations, with a consequent financial loss to the Company. This risk is primarily derived from economic and financial factors, or the possibility of a counterparty’s default or more strictly technical, commercial or administrative factors.

As regards the credit risk involved in trade receivables derived from the Company’s commercial activities, this risk has been historically limited given the short term for collection from customers, which implies that no significant individual amounts are accumulated. The Company has the power to cut supply in case of a customer’s failure to make payment; this tool is used and makes the process of credit risk assessment and control easier.

Allowances for doubtful accounts are recorded (i) for the exact amount of any claims representing an individual risk (risk of bankruptcy, customers involved in legal proceedings against the Company); (ii) for claims other than those described in (i), provisions are recorded for customer segments taking into account the age of claims and historical charges for uncollectible amounts. According to the policy currently in effect, the Company provides for 100% of any unpaid claims overdue for more than one year. Total overdue balances not covered by provisions for bad debts amount to Ps. 26,813 thousand as of December 31, 2012, and to Ps. 52,101 thousand as of January 1, 2012.

The Company has a wide range of customers, including residential, commercial, industrial – small and big – customers and governmental entities.

Also, credit risk affects cash and cash equivalents, and bank and financial entity deposits, the Company do its financial operations in first rate entities.

The Company’s maximum exposure to credit risk as of December 31, 2012, broken down by type of financial instrument, is detailed below:

	Maximum exposure as of
		12.31.12	01.01.12
Cash and cash equivalents		153,208	207,278
Trade receivables and other receivables		262,821	237,729

METROGAS S.A.

ANNEX I – ADDITIONAL INFORMATION AS OF DECEMBER 31, 2012 AND JANUARY 1, 2012

(amounts in thousands of pesos, except where expressly stated otherwise)

As of December 31, 2012, the allowance for doubtful accounts amounts to Ps. 15,447 thousand. This provision represents the best Company’s estimate of losses incurred in relation to trade receivables.

Note 11 of this Annex details the aging of trade and other receivables.

4.1.3

Liquidity Risks

Liquidity risk represents the Company’s inability to meet its short and long-term financial commitments.

At present the Company’s liquidity is one of the main items on which Management’s attention is focused, due to the difficulties that the Company is going through. The absence of rate increases, constantly increasing operating costs and the lack of certainty as to the effective implementation of rate increases are factors that have a direct impact on MetroGAS liquidity.

During 2012, MetroGAS decided to modify the terms of payment for gas producers and no assurance may be given as to when this may be modified in the future. Consequently, as of December 31, 2012 MetroGAS recorded a negative working capital of Ps. 28,440 thousand under IFRS.

MetroGAS continues to encourage negotiations in an attempt to reach an agreement that may contemplate tariff arrangements so as to restore the feasibility of its business. If current circumstances continue, the Company has contemplated a number of actions to be taken in order to mitigate the impact of its financial condition, including to:

Bring claims for rate increases (including the transfer thereto of any municipal taxes) before Argentine authorities;

Make efforts to achieve a strict cash management and expense control;

Demand additional capital contributions from Company shareholders;

Renegotiate payment terms with major suppliers and Trusts Funds; and

Obtain funding from third parties.

In spite of the fact that the Company is already taking some of the actions referred to above, its future remains uncertain.

In the table below the maturities of financial liabilities as of December 31, 2012 are detailed:

	12.31.12

5.1	Determination of Fair Value

IFRS 9 defines the fair value of financial instruments as the amount obtainable from an exchange of a financial asset or from payment of a financial liability in an arm’s length transaction between knowledgeable, willing parties. All financial instruments recognized at fair value are assigned to one of IFRS 7 hierarchical levels, which are three. The initial basis for assignation is the “type of economic investment”. Pursuant to IFRS 7, the valuation methods used to determine fair value must maximize the use of observable data.

Fair-value measurement of MetroGAS financial instruments is classified according to the three levels established by IFRS 7:

- Level 1: Fair value is determined on the basis of observed prices in an active market for identical assets or liabilities that the Company may take as benchmark at the end of the fiscal year. An active market is a market with a high level of trading, and sufficient permanently available information on prices. As an observed price in an active market is the most reliable indicator of fair value, this price, if available, is always to be used.

- Level 2: Fair value is determined on the basis of observable information other than observed prices mentioned in Level 1 for financial asset or liabilities, whether directly (for instance, prices) or indirectly (for instance, derived from prices).

- Level 3: Fair value is determined through unobservable indicators and the company is required to develop its own hypotheses and premises. This is only allowed to the extent no market information is available. Any data included reflect the estimates that a market participant would take into account to set prices. The Company uses the best available information, including in-company data. MetroGAS does not have any financial instruments qualifying as Level 3 instruments.

8.	PROVISIONS

8.1	Turnover Tax (Province of Buenos Aires)

During 1994, the Province of Buenos Aires agreed with the Argentine Government that the Province would not impose turnover taxes on sales of natural gas at a rate in excess of 3.5% of the prices billed for those sales. In spite of the fact that the Province increased such tax rate and instructed MetroGAS to include the rate increase in the bills of the customers and to remit the revenues so collected to the Province, MetroGAS declined to follow those instructions on the basis of the agreement between the Province and the Argentine Government described above.

On December 22, 2005, through Resolution No. 907/05, the Tax Authority of the Province of Buenos Aires notified MetroGas the commencement of a Tax Determination Procedure for the fiscal periods 2001 through March 2003 claiming the payment of the amounts that would have been collected from customers, if the tax rate increase described above had been applied (currently it amounts approximately to Ps. 29 million, including penalties and fines). The Resolution was appealed on January 16, 2006, before the Tax Court of the Province of Buenos Aires.

On September 27, 2006, Ruling No. 112/06 [Fallo Plenario] of the Federal Tax Commission ratified the criterion followed by the Company and declined a motion to reopen the case [recurso de revision] filed by the Province of Buenos Aires on the basis of a case identical to MetroGAS. The Province of Buenos Aires filed an extraordinary appeal against such Ruling before the same Federal Tax Commission for its final resolution by the Argentine Supreme Court of Justice.

The Argentine Supreme Court of Justice granted the extraordinary motion but so far the case is still pending a final decision.

On March 3, 2008, through Resolutions No. 95/08, No. 96/08 and No. 97/08, the Tax Authority of the Province of Buenos Aires notified MetroGAS the Tax Determinations carried out for the fiscal periods January 2004 through October 2005. The claim is based on the increase of the tax rate described above and certain differences with respect to the determination of income and expense ratios. The amount claimed approximately amounts to Ps. 48 million, including penalties and fines. On March 27, 2008, those resolutions were appealed before the Tax Court of the Province of Buenos Aires, and to the date of these financial statements are still pending resolution.

In the event that MetroGAS should be finally compelled to pay for such amounts, the Company will request a reallocation of such tax rate increase to the tariffs paid by customers in compliance with the terms of the License.

At December 31, 2012 and January 1, 2012, the Company maintained a provision of Ps. 24,363 thousand and of Ps. 18,811 thousand, respectively, for any contingencies with respect to differences of determination of the income and expenses ratios.

8.2	Taxes, Rates and Contributions

Through Resolution No. 2,778/03, the ENARGAS decided that MetroGAS had collected excess amounts on account of taxes, rates and contributions from its customers of Ps. 3.8 million and set a fine of Ps. 0.5 million. The Company filed in due time a special appeal (recurso de reconsideración con alzada en subsidio) against ENARGAS Resolution and against the interest rate applied on the fine. As of December, 31, 2012 and January 1, 2012, the total amount demanded by the ENARGAS amounted to Ps. 24,464 thousand and Ps. 23,393 thousand, respectively, including penalties and fines, and recorded the respective provision.

8.3	Government of the City of Buenos Aires’ Fines – Works on Roads and Public Spaces

Law No. 2,634, published on January 25, 2008, and its Regulatory Decree No. 238/08 published on March 28, 2008, created and regulated a new regime for openings and/or breaks works on public spaces and roads within the City of Buenos Aires. The regime specifies the charges to pay for all works on public spaces and establishes that backfilling works have to be made by the Government of the Autonomous City of Buenos Aires, previous payment by those companies authorized to make any such works. Subsequently and effective November 1, 2009, the Government of the Autonomous City of Buenos Aires further modified the procedure to repair sidewalks and established that those companies that have proceeded to break up a public space shall be responsible for the complete repair and backfilling.

The Special Infractions and Misdemeanors Control Agency of the GCABA has imposed penalties on MetroGAS in several cases. The Company is filing the relevant disclaimers before the administrative authorities, and requesting the transfer to a court hearing minor cases to carry out the corresponding defenses at that stage, in order to obtain the declaration of unconstitutionality of the law, the unreasonableness of the infractions imposed and consistently the denial of those penalties. As of December 31, 2012 and January 1, 2012, the Company has created a provision of Ps. 6,290 thousand and Ps. 2,554 thousand, respectively.

8.4	Interpretative Disagreements with Regulatory Authorities

At the date of approval of these financial statements, The Company has several interpretative disagreements with the aforementioned regulatory authorities with respect to various legal issues. As of December 31, 2012 and January 1, 2012, the Company recorded provisions for any such disagreements of Ps. 9,941 thousand and Ps. 10,839 thousand, respectively.

13.	CAPITAL STOCK

As of December 31, 2012, the capital stock of MetroGas amounts to Ps. 569,171 thousand, which is fully subscribed, registered and paid-in:

Classes of shares	Thousands of Ps
Outstanding:
Book-entry common shares, with a par value of Peso one each, and the right to one vote per share:
Class “A”		290,277
Class “B”		221,977
Class “C”		56,917
Capital Stock at 12.31.12		569,171

The most recent capital increase that raised the capital stock to Ps. 569,171 thousand was approved by the General Extraordinary Shareholders’ Meeting held on March 12, 1997. This capital increase was authorized on April 8, 1997 by the CNV and on April 10, 1997 by the Buenos Aires Stock Exchange and was registered with the Public Registry of Commerce on June 17, 1997 under No. 6,244 of Book 121, Volume “A” Sociedades Anónimas.

The capital stock of the Company is composed as follows: 70% is held by the investment company Gas Argentino; 20%, which was originally owned by the Argentine Government, was offered through a public offering as described below and the remaining 10% is subject to the Employee Stock Ownership Plan (the “ESOP”).

In accordance with the Transfer Agreement, the Argentine Government sold 20% of its capital stock in MetroGas through a public offering, represented by 102,506,059 Class “B” shares, which shares are held by private investors.

On November 2, 1994, the CNV through Resolution No. 10,706 authorized the listing of the total number of shares comprising the capital stock of the Company at such date. At the same time, ADSs were issued in the United States of America and registered with the Securities & Exchange Commission (“SEC”). The Company’s shares are traded on the Buenos Aires Stock Exchange (“BCBA”) and the ADSs are traded on the New York Stock Exchange (“NYSE”), respectively. On June 17, 2010, the NYSE informed MetroGAS that the ADSs had been suspended from trading on the NYSE as a result of the announcement of the filing of a petition for the Company’s reorganization proceedings on that date.

On December 31, 2012, the accumulated losses exceeded more than 50% of the capital stock and the legal reserves of the Company. For this reason, MetroGAS fell within the scope of Section 206 of Argentine Companies Law No. 19,550, which stipulates a mandatory capital reduction.

The shareholders’ equity items have been valued in accordance with the Argentine generally accepted accounting principles in force on the transition date. Movements in this account have been accounted for in accordance with the corresponding legal or statutory regulations and the decisions adopted by the shareholders’ meetings, and although said items would have had a different balance in the past if the IFRS had been applied.

13.1 Employee Stock Ownership Plan

National Executive Power Decree No. 1,189/92, which provides for the creation of the Company, establishes that 10% of the capital stock represented by Class “C” shares has to be included in the Employee Stock Ownership Plan (“ESOP”), as required by Law No. 23,696, Chapter III. The transfer of the Class “C” Shares was approved on February 16, 1994 by Executive Order No. 265/94. The Class “C” shares shall be held by a trustee for the benefit of the employees of “Gas del Estado” transferred to MetroGAS, who remain being employed by MetroGAS on July 31, 1993 and who elect to participate in the ESOP.

In addition, the Company’s By-laws provide for the issuance of profit sharing bonds as defined in Section 230 of Law No. 19,550 in favor of all regular employees, distributing 0.5% of the net earnings of each year among the beneficiaries of this program. Accrued amounts will be deductible as expenses in the statement of comprehensive income for each year, in so far as there are appropriated retained earnings.

ESOP participants acquired their shares from the National Government for Ps. 1.10 per share, either paying in cash or applying the dividends on any such shares and a 50% of their profit-sharing bonds to the purchase price. The trustee will maintain the Class “C” shares in custody until they are paid in full.

Once Class “C” shares are fully paid, they may be converted into Class “B” shares at the request of the holders. The decision regarding the conversion of Class “C” shares must be taken by the holders of said Class “C” shares, acting as a single class. So long as the requirements set forth in this plan are not met, neither the By-laws of the Company nor the relevant shareholding percentages may be changed.

On March 6, 2008, the Board of Directors of MetroGAS approved the procedure for the conversion of the Class “C” shares into Class “B” shares requested by the ESOP Executive Committee by the note dated March 3, 2008.

On May 21, 2008, the CNV notified MetroGas that the conversion procedure is subject to the presentation of the National Government Resolution approving the payment of the purchase price balance of the Class “C” shares. The early cancellation was approved by the Ministry of Economy and Production (“ME”) through Resolution No. 252 on August 22, 2008.

On December 30, 2008, the ESOP Executive Committee requested MetroGAS to suspend the conversion procedure presented before the CNV and the BCBA until further notice.

Refers to the creation of a Global Note Program for the issuance of simple non-convertible negotiable obligations approved by the General Extraordinary Shareholders´ Meeting held on December 22, 1998.

Refers to the Global Note Program referred to in point (1) extended for 5 years by the General Extraordinary Shareholders´ Meeting held on October 15, 2004 and subsequently extended for another additional period of 5 years by the General Extraordinary Shareholders´ Meeting held on February 24, 2010.

Notes of this Series will bear an annual interest rate of 8% for the years 2006-2010 and 9% thereafter.

Notes of this Series will bear an annual interest rate of 3% for the year 2006, 4% for the years 2007-2008, 5% for the years 2009-2010, 7% for the years 2011-2012 and 8% thereafter.

Notes of this Series will bear an annual interest rate of 1.8% for the year 2006, 2.8% for the years 2007-2008, 3.8% for the years 2009-2010, 5.8% for the years 2011-2012 and 6.8% for the years 2013-2014.

The principal amortization schedule according to the original terms and conditions of issuance is as follows: 5% on June 30 and December 31, 2010; 10% each June 30 and December 31 thereafter until December 31, 2012 and 12.5% each June 30 and December 31 thereafter until December 31, 2014.

The principal amortization schedule according to the original terms and conditions of issuance is as follows: 16-2/3% on June 30 and December 31, 2012; 16-2/3% each June 30 and December 31 thereafter until December 31, 2014.

Financial income have been accruing until the date of filing of the reorganization proceedings (concurso preventivo), at which time the accrual of interest was suspended according to Section 19 of Argentine Bankruptcy Law.

Filing a petition for Reorganization Proceedings gave rise to an event of default under the Global Note Program of MetroGAS which automatically accelerated the maturity of any outstanding balances on the debt. Nevertheless, commencement of the reorganization proceedings suspends any principal and interest payments on the reorganization debt (including the financial debt) of MetroGAS.

26.	CONTRACTUAL COMMITMENTS

In order to satisfy the demand of natural gas and provide the licensed service efficiently, MetroGAS has entered into various long-term contracts from the commencement of the concession to ensure certain purchasing and transportation capacity of gas.

26.1	Purchases of Gas

The main suppliers of the Company are: YPF, Total Austral, Wintershall Energía, Pan American Energy, and other producers of the Provinces of Tierra del Fuego, Neuquén and Santa Cruz, Argentina.

On June 14, 2007, the Argentine Secretariat of Energy published Resolution No. 599/07 in the Official Bulletin approving the proposal for the “Agreement with Natural Gas Producers 2007-2011”, latter ratified by certain natural gas producers and becoming effective. Basically, the Agreement with Natural Gas Producers 2007-2011 establishes the volumes to be injected at the points of entry to the transportation system by natural gas producers for residential, commercial, industrial, power plants and CNG supply stations customers until December 31, 2011 (although the contractual terms differ depending on the category of consumer) and indicates certain price adjustments payable in installments depending on the type of consumer. The Resolution that approves the Agreement 2007-2011 (Resolution ES No. 599/07) establishes the mechanisms to re-route and inject additional natural gas to satisfy the demand of the domestic market where appropriate in the event of any shortages. In accordance with the Agreement with Natural Gas Producers 2007-2011, producers and distribution companies had to enter into gas purchase and sales agreements reflecting the terms and conditions included therein.

MetroGAS did not enter into any of these agreements at the appropriate time because it understood that the offers received from the producers neither comply with the terms and conditions of the Agreement with Natural Gas Producers 2007-2011, nor would allow MetroGAS to guarantee the supply of natural gas to the Company´s consumers on an uninterruptible basis considering the volumes included in said offers.

As from August 1, 2007, based on the provisions of the Agreement with Natural Gas Producers 2007-2011 and according to several notes issued by the Sub-secretary of fuels and Circulars distributed by the EGM, the volumes set forth under said Agreement became effective as provision arrangements, provided that there are no contracts with gas producers.
