ENERSIS

ANNOUNCES CONSOLIDATED RESULTS

FOR THE PERIOD ENDED ON MARCH 31, 2013

Highlights for the Period

Ø The negative variation upon the Operating Income is mainly attributable to the drought in Brazil, which has forced distribution Companies to absorb higher energy purchase costs. Part of this over cost is in the process of being reimbursed through tariff revision processes. Taking away this effect, the Operating Results would have been in line with those as of March 31, 2012.

Ø Operating revenues decreased 10.3%, reaching Ch$ 1,456,669 million primarily as a consequence of lower energy sales revenues in distribution business due to lower tariffs in Coelce and Chilectra. On the other hand, demand for electricity showed a growth level lower than expected, as a consequence, among other reasons, of less calendar days, more holidays and more stable temperatures. All of them non permanent changes variables. Demand for electricity, in every country, was as follows:

·        Peru                   5.5%
·        Chile                  2.2%
·        Colombia           1.4%
·        Brazil                 0.3%
·        Argentina          -1.1%

Ø Physical sales in distribution increased 371 GWh, or 2.0%, while in generation, physical sales decreased 443 GWh, equivalent to 2.8%.

Ø Another factor that helps to understand the variation of the revenues is the effect in generation of lower average energy sale price and the drop on energy sold, that partially offset the addition of almost 410 thousand new customers among the distribution companies.

Ø Procurement and Services costs decreased 12.9%, reaching Ch$ 800,589 million, as a consequence of lower energy purchases costs of Ch$ 36,263 million,
lower transportation cost of Ch$ 26,192 million, and lower fuel consumption cost of Ch$ 16,680 million. This positive reduction in operating costs is mainly explained by the operation of Bocamina II, and was partially offset by:

o The drought affecting Brazil, which pushed up the energy prices, and the fact that until now part of the incremental energy purchase costs has not been recognized in the distribution companies tariffs.

o Salaries in Edesur were increased by government mandate in an 18% retroactively to January 2013, increasing in a significant way operating costs.

Ø The Company’s EBITDA amounted to Ch$ 434,041 million during this quarter, 11.5% lower when compared to the same period in 2012. Good performance in generation business partially offset the negative operational behavior in distribution business.

3M 2013

Ø Financial result was a Ch$ 57,491 million loss, 32.0% better than first quarter 2012. This improved result is mainly explained by higher financial revenues of Ch$ 8,566 million and lower financial costs of Ch$ 7,612 million.

Ø Due to the above mentioned variations, Net Income before taxes reached Ch$ 277,600 million, equivalent to a 5.7% reduction.

Ø Taxes increased by Ch$ 18,939 million, mainly due to increases in taxes explained mainly.

o Enersis by Ch$ 7,282 million, due to higher tax expenses as a result of lower deferred tax of shares issued in the capital increase of Ch$ 3,640 million and Ch$ 3,156 million because of Swap variation.

o Endesa Chile of Ch$ 13,383 million, due to higher tax expense as a result of lower deferred tax due to reduction in tax loss of Ch$ 6,589 million, conversion effect of Ch$ 3,680 million and Ch$ 2,867 related to fixed asset variation.

Ø This higher tax expenses explains the decrease of 15,4% in net income.

Ø The diversified portfolio of Enersis Group allowed us to maintain a well balanced contribution to our EBITDA by business segment,

• Distribution: 46%

• Generation and Transmission: 54%

Generation and Transmission Business

Ø Operating revenues decreased 7.4%, reaching Ch$ 575,608 million, due to lower physical sales and lower average energy sale price expressed in Chilean pesos.

Ø Procurement and services costs decreased 15.6% to Ch$ 285,883 million as result of a reduction in all of its lines, mainly in energy purchases costs of Ch$ 17,634 million, fuel consumption costs of Ch$ 16,677 million and transportation expenses of Ch$ 16,242 million.

Ø EBITDA amounted to Ch$ 236,136 million, equivalent to a reduction of 4.4%.

Ø Consolidated electricity generation decreased by 0.1% to 13,983 GWh, mainly explained by Argentina, Peru and Colombia, partially offset by increases in Chile and Brazil.

Ø Consolidated physical sales decreased 2.8% to 15,640 GWh, mainly because of Argentina, Peru, Brazil and Chile, partially offset by Colombia.

EBITDA in the Generation business, by country, was as follows:

In Chile, EBITDA increased by Ch$ 6,209 million, mainly due to:

Ø Lower energy purchases cost of Ch$ 38,941 million due to higher thermal generation as a result of the start up of Bocamina II operations, added to lower fuel consumption costs of Ch$ 14,344 million and lower transportation cost of Ch$ 14,059 million.

Ø This was partially offset by lower energy sale revenues of Ch$ 52,867 million due to lower average energy sale prices and lower physical sales as a result of reduced contracts indexed to marginal cost and the expiration of some contracts with non regulated customers.

PRESS RELEASE
3M 2013

In Argentina, EBITDA decreased by Ch$ 353 million due to:

Ø Lower operation revenues of Ch$ 4,601 million, as a consequence of a reduction in the average energy sale prices expressed in Chilean peso terms and lower physical sales due to a reduction in hydro generation as a result of lower reservoir levels.

Ø This was partially offset by lower fuel consumption cost of Ch$ 3,443 million because of lower thermal generation.

In Colombia, EBITDA grew by Ch$ 6,655 million, mostly in connection with,

Ø Increase in operating revenues of Ch$ 18,065 million explained by 11.0% increase in the average energy sale price in Chilean peso terms, in line with a higher market price in Colombia, and 2.6% increase in physical sales due to higher demand.

Ø This was partially offset by higher energy purchases costs of Ch$ 14,715 million mainly due to a lower hydro availability.

In Peru, EBITDA remained very similar to the one recored on the same period last year, with an increase of Ch$ 299 million due to:

Ø Lower procurement and service cost of Ch$ 4,259 million mainly explained by lower fuel consumption as a result of the better hydro availability.

Ø Lower other operating costs of Ch$ 1,148 million.

Ø The latter was partially offset by a Ch$ 5,159 million reduction in operating revenues of Ch$ 5,159 million due to lower average energy sale price in Chilean peso terms and lower physical sales.

In Brazil, EBITDA decreased by Ch$ 4,186 million basically because of:

Ø Higher procurement and services costs of Ch$ 10,942 million, mainly explained by higher energy purchases costs of Ch$ 7,247 million, both, in Central Fortaleza and Cachoeira Dourada.

Ø Higher fuel consumption cost of Ch$ 5,431 million, also explained by higher generation in Endesa Fortaleza.

Ø This was partially offset by higher energy sale revenues of Ch$ 7,559 million, due to higher thermal generation in Fortaleza, that offset the lower hydro availability in Cachoeira Dourada.

Distribution Business

Consolidated figures for the distribution businesses are detailed as follows:

Ø Operating revenues reduced by 11.8% compared to the first quarter 2012, reaching Ch$ 1,018,042 million. This is explained mainly by the tariff revision process in Coelce and Chilectra which resulted in tariff reductions.

Ø Procurement and service costs reached Ch$ 654,946 million, 11.0% lower than in first quarter 2012. This is mainly explained by reductions in energy purchases cost, other procurement and service cost and transportation cost.

Ø Energy sales by customers’ segment for each of our distribution companies were the following:

EBITDA in the Distribution business, by country, was as follows:

In Chile, EBITDA decreased by Ch$ 1,026 million, mainly attributable to:

Ø Lower energy sales revenues due to lower average energy sale price, explained by the tariff revision process in Chilectra since November 2012.

Ø The above was partially offset by a 2.8% increase in physical sales, as a result of higher economic activity, and higher other operating revenues.

In Argentina, EBITDA decreased by Ch$ 13,212 million, mostly explained by:

Ø Increase of Ch$ 8,423 million in personnel expenses, due to salary increases because of union agreements.

Ø Increase of Ch$ 3,716 million in other fixed operating costs because of higher costs in inputs and services hired to make some repairs to the grid.

In Peru, EBITDA remained almost the same, reaching Ch$ 22,490 million, equivalent to 0.2% decrease, basically as consequence of:

Ø Reduction in other operating revenues of Ch$ 1,381 million and higher energy purchase cost of Ch$2,647 million.

Ø This was partially offset by an increase of Ch$ 3,246 million in energy sales revenues, due to higher physical sales and higher average energy sale price expressed in Chilean peso terms.

Financial Summary

Pg. 4

PRESS RELEASE
3M 2013

Ø Average nominal interest rate decreased from 9.7% down to 8.0%, mainly explained by a lower inflation rate in Chile and better rate conditions in the countries where we operate.

Ø Liquidity, a key consideration in our financial management, continues to be in a very solid position, as shown below on a consolidated basis for Enersis,

· Cash and cash equivalents US$ 3,055 million

· Committed credit lines available US$ 697 million

· Non-committed credit lines available US$ 1,065 million

Ø Hedge and protection: In order to mitigate exchange rate and interest rate risks, Enersis has established strict internal rules to protect our cash flows and balance sheet from fluctuations in these variables.

· Our exchange rate policy is based on cash flows and we strive to maintain a balance between US dollar indexed flows, and assets and liabilities in such currencies. In addition to this policy, we have contracted cross currency swaps for a total amount of US$ 1,490 million and forwards for US$ 479 million as of March 31, 2013.

· In order to reduce financial results volatility due to changes in market interest rates, we seek to maintain an adequate balance in our debt structure. Thus, as of March 31, 2013, we have contracted interest rate swaps (from variable to fixed rates) for US$ 460 million.

Market Summary

Ø During the period from April 2012 to March 2013, the Chilean Stock Exchange’s index for the most important 40 shares, “IPSA”, showed a decrease of -5.1%. The markets where the Company operates recorded mixed performance, as follows:

This change is mainly attributable to the impact of the capital increase announced on July 25, 2012, as well as because of a still global economic scenario, especially in the European zone and also due to the drought affecting Chile for the last three consecutive years.

Ø On the other hand, Enersis` ADS value decreased -4.7% reaching a price of US$19.2, while its share price in the Madrid Stock Exchange decreased 0.7% reaching €$0.30 as of March 31, 2013.

Net Financial Income

The Company’s net financial income as of March 31, 2013 totaled a loss of Ch$ 57,492 million, 32.0% lower than in the forst quarter 2012. The latter is mainly explained by:

Higher financial revenues by Ch$ 8,566 million, as a consequence of the actualization in Brazil of unamortized assets at the end of the concession in Ampla and Coelce in Brazil to new replacement value depreciated by Ch$ 19,308 million, partially offset by lower revenues by cash deposits of Ch$ 4.365 million, lower revenues by juditial deposits reversal in Brazil of Ch$ 2,748 million, lower revenues by financing and conventions of Ch$ 768 million and lower extraordinary financial revenue by ESSALUD received in 2012 in Edelnor of Ch$ 1,500 million.

Lower financial expenses of Ch$ 7,612 million as a result of a decrease in financial costs of loans and bonds of Ch$ 5,527 million and the lower contingencies actualization of Ch$ 5,749 million. This was partially offset by higher contingencies actualization of Ch$ 3,600 million and higher expenses for derivatives valuation of Ch$ 563 million.

Lower adjustment units expenses of Ch$ 5,757 million due to the effect of the UF¹ change mainly over UF denominated debt in some companies in Chile. This as a result of the 2012 period where the UF increased its value by 0.1% compared with the 1.1% increase during same period last year.

Lower exchange rate expense of Ch$ 5,150 million, mainly explained by revenues due to exchange rate variation in cash and cash equivalent of Ch$ 4,790 million and in debtors and other accounts receivable in US dollars of Ch$ 2,206 million and losses in liabilities of Ch$ 1,846 million.

Sale of Assets

Net income from sales of assets presented a positive variation of Ch$ 2,453 million, due to the benefit obtained from the sale of a transmission line of Ch$ 2,532 million.

This was partially offset by decreases in Coelce of Ch$ 9,202 million, San Isidro of Ch$ 2,353 million, Edegel of Ch$ 1,913 million and Endesa Fortaleza of Ch$ 997 million.

v Increase in trade and other account receivables by Ch$ 60,101 million, explained by increases in Ampla of Ch$ 52,690 million due to account receivables related to incremental cost in energy purchase, in Enersis of Ch$28,323 million, related to accounts receivables of the stock auction from March 28, 2013, in Emgesa of Ch$ 12,821 million due to higher billing, in Coelce of Ch$ 8,893 million, mainly due to account receivables related to incremental cost in energy purchase, in Edelnor of Ch$ 8,822 million due to higher customer billing, and to increases due to the incorporation in the consolidated financial statements of the companies included in Enersis’ capital increase operation which include balances in Dock Sud of Ch$ 24,210 million, and Caboblanco of Ch$ 3,462 million. Tha latter was partially offset by reductions in Endesa Chile of Ch$ 74,291 million due to Bocamina II insurance’s payment and lower billing in this period, and reduction in Pehuenche of Ch$ 9,271 million.

v Increase in current taxes assets by Ch$ 32,695 million due to increases in Endesa Chile of Ch$ 8,394 million due to higher provisional taxes payments and value added tax (VAT) credit pending to apply, in Ampla of Ch$ 8,155 million due to VAT credit pendant to apply, in San Isidro of Ch$ 1,728 million, in Endesa Fortaleza of Ch$ 1,198 million due to higher tax payments and to the incorporation in the consolidated financial statements of the companies included in Enersis’ capital increase operation which include balances in Cemsa of Ch$ 7,452 million, Dock Sud of Ch$ 3,513 million and Caboblanco of Ch$ 3,497 million.

v Increase in non-tangible assets other than goodwill of Ch$ 19,317 million, mainly explained by new investments of Ch$ 32,525 million, by convertion effect of Ch$ 4,826 million and by the incorporation of the new companies in Enersis consolidation of Ch$ 2,875 million. This was partially offset by reduction of Ch$ 18,721 million for period amortization and for retirements or disposal of Ch$ 885 million.

v This was partially offset by:

v Decrease in property, plant and equipment of Ch$ 36,339 million mainly explained by decrease by conversion effect, due to the different currencies used by the Company of Ch$ 154,515 million, to amortization of the period of Ch$ 83,255 million and disposal of Ch$ 3,245 million, partially offset by new investments of Ch$ 90,305 million and the incorporation of the companies included in Enersis’ capital increase operation of Ch$ 114,175 million.

Book Value and Economic Value of Assets

Regarding the more important assets, the following should be mentioned:

Properties, Plants and Equipment are valued at their purchase cost, net of the corresponding accumulated depreciation and impairment loss Properties, Plants and Equipment, net of their residual value, if applicable, are linearly depreciated by distributing the cost of their different elements along the estimated years of useful life, which is the period that the companies expect to use them. The useful life is reviewed regularly.

The goodwill value generated by consolidation represents the acquisition cost surplus on the Group’s stake in terms of the reasonable value of assets and liabilities, including the identifiable contingent liabilities of a subsidiary at the time of acquisition. Goodwill is not amortized. Instead, at the closing of each accounting period an assessment is made of whether any impairment has occurred during the period that could reduce its recoverable value to an amount below the registered net cost, proceeding in this event to make a timely impairment adjustment (See Note 3.e to the Consolidated Financial Statements).

Throughout the fiscal year and in particular at the date of closing, an assessment is made as to any indication of possible loss due to the impairment of any asset. In the event of any such indication, an estimate of the recoverable sum of said asset is made to determine, if applicable, the depreciated amount. If this involves identifiable assets that do not originate independent cash flows, the recoverability of the Cash Generating Unit that the asset belongs to is estimated, understanding as such the smaller group of identifiable assets that generate independent cash incomes.

Assets expressed in foreign currency are expressed at the prevalent exchange rate at the closing of the period.

Notes and accounts receivable from related companies are classified according to their short and long term maturities. These operations are adjusted according to prevalent market equity conditions.

In summary, assets are valued according to the International Financial Reporting Standards, whose criteria are expressed in Note 3 of the Consolidated Financial Statements.

Ø Current liabilities increased by Ch$ 456,113 million, equivalent to 19.4%, mainly due to:

v Increase of other current financial liabilities of Ch$ 371,287 million, due to increases in Enersis of Ch$ 298,907 million due to transfer of debt to short-term, in Codensa of Ch$ 40,665 million due to to transfer to short-term, in Ampla of Ch$ 7,356 million due to higher debt level, in Coelce of Ch$ 4,417 million to transfer to short-term and accrual of interest, added to the effect of the incorporation in the consolidated financial statements of the companies included in Enersis’ capital increase operation which include balances in Dock Sud of Ch$ 44,153 million, Cabo Blanco of Ch$ 3,811 million and Generalima of Ch$ 3,323 million.

v Increase in trade and other current payables of Ch$ 129,625 million mainly due to increases in dividends payments of Ch$ 136,339 million, increase payments to suppliers of Ch$ 43,617 million and other accounts payables of Ch$41,364 million. This was partially offset by decreases in goods and services account payables of Ch$ 86,446 million and in fuel and gas suppliers of Ch$ 3,431 million

Partially offset by:

v Decrease in accounts payable to related companies of Ch$ 26,976 million mainly due to dividend payment to Endesa Latinoamérica of Ch$ 27,409 million, reduction in account payable to Cemsa of Ch$ 27,831 million due to its incorporation in Enersis’ perimeter, and lower gas purchase to GNL Quintero of Ch$ 18,622 million. This was partially offset by the increase in loans with Endesa Latinoamérica due to the incorporation of Dock Sud to Enersis of Ch$ 46,719 million.

v Decrease of other current non financial liabilities of Ch$ 13,358 million mainly due to decline in Edelnor of Ch$ 11,640 million due to long term transfer of the deferred revenues related to the electric train works.

Ø Non-Current liabilities decreased by Ch$ 392,134 million, equivalent to 9,9%, mainly explained by:

v Decrease in other non-current financial liabilities (borrowings and derivatives) of Ch$ 410,464 million, mainly in Enersis of Ch$ 300,529 million, due to transfer to the short-term of US$ denominated bond and and swap derivative, in Codensa of Ch$ 75,254 million due to transfer to the short-term and conversion effect, in Emgesa of Ch$ 45,170 million due to transfer to the short-term and conversion effect, in Edegel of Ch$13,610 million due to transfer to the short-term, in Endesa Chile of Ch$ 6,273 million due to conversion effect, in Chocón of $3,791 million due to transfer to the short-term and conversion effect and in Endesa Costanera of Ch$ 1,759 million due to transfer to the short-term. This was partially offset by the incorporation of Cabo Blanco of Ch$ 35,962 million.

v Increase in other non-current non-financial liabilities of Ch$ 14,888 million mainly due to increases in Edelnor of Ch$ 12,701 million due to transfer to long-term of the anticipated revenues related to the electric train works and to the incorporation of Dock Sud in Enersis’ perimeter of Ch$ 5,013 million.

Equity increased by Ch$ 1,049,308 million when compared to the same period of 2012:

v The equity attributable to shareholders of the Company increased by Ch$ 2,021,844 million, explained mainly to the increase in issued capital of Ch$ 2,844,398 million, to the net income of the period discounting the minimum dividend of Ch 58,970 million, partially offset by negative reserves of Ch$ 881,523 million, highlighting the effect on reserves of the difference between the book value and the value of the assets contributed in the capital increase operation of Ch$ 855,970 million, conversion differences in the period of Ch$ 18,493 million, capital increase expenses of Ch 13,100 million net from the incremental price obtained in the shares auction and positive hedge reserves of Ch$ 5,628 million.

v Non-controlling interest decreased by Ch$ 972,537 million, explained mainly by the reduction of minority part due to the contribution in kind of the capital increase operation of Ch$ 1,033,247 million, partially offset by the comprehensive result of the period of Ch$ 60,710 million.

The liquidity ratio as of March 31, 2013 was 1.20 times, showing a 22.4% increase compared to March 31, 2012. This reflects the cash received by the capital increase operation ended on March 28, 2013 which leaves the company in an excellent liquidity position.

The leverage ratio is 0.79 times as of March 31, 2013, reducing by 12.2% compared to March 31, 2012, which is a consequence of the equity increase due to the capital increase operation.

The financial expenses coverage shows an increase of 0.13 times, equivalent to 3.4%, moving from 3.82 times as of March 31, 2012 to 3.95 times as of March 31, 2013. This is the result of the decrease in the company’s financial cost in this period and the decrease in EBITDA.

The profitability indicator, operating income over operating revenues, fell 2.4% to 22.3% as of March 31, 2013.

On the other hand, the annualized return on equity of the shareholders of the Company is 7.3%, with a 24.7% drop compared to March 31, 2012 when it was 9.8%. This was a consequence of the increase in shareholder’s equity due to the capital increase operaion, whose benefits will be register starting April 2013.

The annualized return on assets moved from 6.9% as of March 31, 2012 to 6.2% in March 31, 2013 as a result of the increase of the company’s assets mainly due to the capital increase operation, and to the lower result obtained this period.

The Main Risks associated to the activities of the Enersis Group

Commercial and Regulatory Risk

The Group’s activities are subject to a broad range of governmental standards and environmental regulations. Any modification of such standards and regulations may affect the Group’s activities, economic situation and operating results.

The Group’s distribution activity is subject to a wide range of rules regarding tariffs and other issues that govern their activities in each of the countries where it operates and which could modify distribution subsidiaries operating results.

The Group’s generation activity is subject to existing hydrological and weather conditions in the geographic zones in which the Group’s hydroelectric generating plants are located. Commercial policies have been planned in order to moderate the possible impact of changes in these variables.

Group’s activities are subject to certain environmental regulation which Enersis fulfills constantly. Modifications applied on such regulations may affect the operations, economic condition or the results of these operations.

Enersis and its operating subsidiaries are subject to environmental regulations which, among other things, require the company to conduct environmental impact studies for future projects, obtaining permits, licenses and other authorizations and the fulfillment of all requirements of those licenses, permits and norms. As any other regulated company, Enersis cannot guarantee:

· The approval from regulators of environmental impact studies.

· That public opposition may not cause delays or modifications to any proposed project and

Pg. 24

PRESS RELEASE
3M 2013

· That laws or regulations may not change or be interpreted in a manner that could adversely affect the operations or the plans for companies in which Enersis or its subsidiaries hold investments.

The group’s commercial activity has been planned to moderate possible impacts resulting from changes in hydrological conditions.

Enersis group’s operations include hydroelectric generation and therefore depend on the hydrological conditions at any time in the broad geographical zones where its hydroelectric generation installations are located. If hydrological conditions produce droughts or other conditions that negatively affect hydroelectric generation, the results could be adversely affected. Enersis has therefore defined as an essential part of its commercial policy not to contract 100% of its total capacity. The electricity business is also affected by atmospheric conditions like average temperatures which govern consumption. The different weather conditions can produce differences in the margin obtained by the business.

Financial situation and the results from operations could be adversely affected if risk exposure weren’t efficiently managed in regards to interest rates, prices of commodities, and exchange rates.

Interest Rate Risk

Interest rate variations modify the fair value of those assets and liabilities that accrue a fixed interest rate, as well as the future flows of assets and liabilities pegged to a variable interest rate.

In compliance with our current interest rate hedging policy, the portion of fixed and/or hedged debt to the total net debt was 76% as of March 31, 2013 on a consolidated basis.

Depending on the Group’s estimates and debt structure objectives, hedging transactions take place hiring derivatives that mitigate these risks. Instruments currently used to accomplish the policy, are interest rate swaps.

The structure of Enersis’ financial debt sort by fixed, protected and variable interest rate, and after derivatives, is as follows:

Net Position:

	Mar. 31 2013	Dic. 31 2012
	%	%
Fixed Interest Rate	76%	60%
Variable Interest Rate	24%	40%
Total	100%	100%

Exchange Rate Risk

The exchange rate risks are mainly related to the following transactions:

Foreign currency debts raised by the Group
Payments for the acquisition of projects related materials to be made on international markets.
Group‘s’ incomes directly linked to the evolution of the dollar, and
Cash flows from our foreign subsidiaries exposed to exchange rate fluctuations.

Pg. 25

PRESS RELEASE
3M 2013

In order to mitigate exchange rate risks, Enersis’ exchange rate hedging policy is based on cash flows and it strives to maintain a balance between dollar indexed flows and the asset and liability levels in such currency. Cross currency swaps and exchange rate forwards are the instruments currently used in compliance with this policy. Likewise, the policy looks to refinance debts in each company’s functional currency.

Commodities Risk

Enersis is exposed to price fluctuation risk on some commodities, basically through

Fuel purchases for the electricity generation and also,
Energy transactions in the local markets.

In order to reduce risks in extreme drought conditions, the company has designed a trading policy that defines sales commitment levels consistent with its generating plants’ firm energy in a dry year, including risk mitigation clauses in some unregulated clients’ contracts.

In view of the operative conditions by the electricity generation market in Chile has experienced, like extreme drought and rising oil prices, the company has decided to hire a derivative to place a cap on the Brent price for consumption. As of March 31, 2013 there are no outstanding coverage instruments and instruments taken in the past have been specific and for no considerable monetary amounts. Market and operative conditions will be constantly analyzed to adjust the volume hedged or take new hedges for the following months.

Liquidity Risk

In engaging committed long term credit facilities and short term financial investments the Group maintains a consistent liquidity policy, for the amounts required to support projected needs for the period, contingent with the situation and the expectations in the debt and capital markets.

As of March 31, 2013, the Enersis Group held liquidity in the amount of Ch$ 1,443,735,890 million in Cash and Cash Equivalent and Ch$ 288,427,000 million in committed long term credit lines. As of March 31st, 2012, the Enersis Group held liquidity in the amount of Ch$ 815,832,061 million in Cash and Cash Equivalent and Ch$ 240,680,000 million in committed long term credit lines.

Credit Risk

Credit risk in accounts receivable, originating from trading activities, has been historically very limited given that the short term collection conditions with customers doesn’t allow them to individually accumulate significant amounts. Additionally, in the case of the so-called “unregulated customers” of our electricity generation and distribution business, a formal procedure is applied to control the credit risk, using a systematic evaluation of our counterparties, index definition and credit risk factors by virtue of which the contracts are approved or additional guarantee requirements are defined.

Furthermore, in our electricity generating business, in the event of non-payment, some countries allow power supply cut-offs, and in almost all contracts a lack of payment is established as cause for contract termination. For this purpose, credit risks are constantly monitored and the maximum amounts exposed to payment risks are measured, which are limited.

Pg. 26

PRESS RELEASE
3M 2013

In turn, in our electricity distribution business, the energy supply cut-off is a power held by our companies in case of default by our customers, applied in accordance with the applicable regulation in each country, enabling the credit risk evaluation and control process, which is also limited.

Surplus cash flow investments are placed in prime national and foreign financial entities (with an investment grade equivalent risk rating) with limits established for each entity.

In the selection of banks for investment, the Group considers those that hold two investment grade classifications, according to the three main international rating agencies (Moody’s, S&P and Fitch Ratings).

Positions are backed up by treasury bonds from the country of operations and instruments issued by the most reputable banks, favoring, wherever possible, the first ones.

Derivatives are engaged with highly solvent entities; about 80% of operations are conducted with entities that hold an A- or higher rating.

Risk Measurement

The Enersis Group measures the Value at Risk (VaR) of its debt and financial derivatives positions in order to guarantee that the risk taken by the company remains consistent with the risk exposure defined by Management, thus restricting the volatility of its financial results.

The positions portfolio used in the calculations of the current Value at Risk is comprised of debt and financial derivatives.

The calculated Value at Risk represents the possible value loss of the aforementioned positions portfolio over one day time horizon with 95% of confidence.

The volatility of the risk variables that affect the value of the positions portfolio has been studied, including:

The U.S. dollar Libor interest rate.
The usual banking local indexes for debts, taking into account the different currencies our companies operate under, and
The exchange rates of the different currencies involved in the calculation.

The calculation of VaR is based on generating possible future scenarios (at one day) of market values (both spot and term) for the risk variables, using Bootstrapping methodology. The number of scenarios generated ensures compliance with the simulation convergence criteria. A matrix of volatilities and correlations between the various risk variables calculated based on the historical values of the logarithmic price return, has been applied to simulate the future price scenario.

Once the price scenarios have been obtained, the fair value of the portfolio is calculated using such scenarios, obtaining a distribution of possible values at one day. The one-day 95% confidence VaR number is calculated as the 5% percentile of the potential increases in the fair value of the portfolio in one day.

The various debt positions and financial derivatives included in the calculation have been valued consistently using the financial capital calculation methodology reported to Management.

3M 2013

Taking in consideration the above mentioned hypotheses, the breakdown for VaR in every mentioned type of positions is the following:

Financial Positions	Dec. 31 2013	Dec. 31 2012
Financial Positions	Th Ch$	Th Ch$
Interest Rate	15,678,476	15,933,808
Exchange Rate	3,687,593	2,346,380
Correlation	(697,519)	(468,249)
Total	18,668,550	17,811,939

Other Risks

A portion of Enersis and Endesa Chile’s debt is subject to cross default provisions. If certain defaults in debt of certain specific subsidiaries are not remedied within specified grace periods, a cross default could affect Endesa Chile and Enersis, and under certain scenarios, debts at the holding company level could be accelerated.

Nonpayment – after any applicable grace period – of the debts of Enersis and Endesa Chile, and in the case of Enersis, its subsidiaries Endesa Chile and Chilectra, with an individual principal amount outstanding in excess of US$ 50 million (or its equivalent in other currencies), and with a missed payment also in excess of US$ 50 million, could give rise to a cross default of several bank revolving debt facilities at the Endesa Chile and Enersis levels. Furthermore, some of these debt facilities are also subject to cross acceleration provisions in the event of a default in other debt of the companies mentioned above, for reasons other than payment default, for events such as bankruptcy, insolvency proceedings, and materially adverse governmental or legal actions, in all cases for amounts in excess of US$ 50 million.

Similarly, nonpayment – after any given applicable grace period - of the debts of Enersis and Endesa Chile or any of their Chilean subsidiaries, in single indebtedness in default with a principal in excess of US$ 30 million, could potentially give rise to a cross default of Enersis and Endesa Chile Yankee bonds.

Finally, in the case of local bonds of Enersis and Endesa Chile, prepayment is triggered only as a result of a default of the Issuer.

There are no clauses in the credit agreements by which changes in the corporate or debt classification of these companies from risk rating agencies could trigger prepayments

ARGENTINA

GENERATION

In Argentina, the operating income for the period amounted to Ch$ 1,837million, representing an increase of Ch$ 1,632 when compared to the first quarter 2012. This is primarily explained by lower procurement and service costs of Ch$ 3,872 million, mainly due to a 9.2% reduction in fuel consumption costs. The foregoing was partially offset by a Ch$ 4,601 million reduction in operating revenues, mainly explained by a decrease of 14.3% in energy sales revenues.

EBITDA from operations in Argentina amounted to Ch$ 6,980 million, 3.6% lower when compared to that recorded in 1Q 2012

Endesa Costanera

Endesa Costanera’s operating income increased by Ch$ 3,928 million, showing a lower negative result of Ch$ 2,156 million in the first quarter of 2013. This is mainly explained by a 9.2% reduction in fuel consumption cost, partially offset by a Ch$ 5,226, or 11.2% reduction in energy sales revenues.

Physical sales reached 2,230 GWh, 6.8% lower than in the same quarter of 2012.

The net effect of translating the financial statements from Argentine pesos to Chilean pesos in both periods led to a 16.3% decrease in Chilean pesos in March 2013, when compared to March 2012.

El Chocón

El Chocón’s operating income reached Ch$ 3,306 million, a 38.2% decrease when compared to the first quarter of 2013. This result is mainly explained by a 19.9% decline in energy sales revenues, due to a 14.6% reduction in average energy sale price, partially offset by lower procurement and service costs of 25.8% mainly due to lower energy purchases of 23.2%.

Physical sales decreased 14.8%, reaching 574 GWh.

The net effect of translating the financial statements from Argentine pesos to Chilean pesos in both periods led to a 16.3% decrease in Chilean peso term in March 2013, when compared to March 2012.

Distribution

Edesur

Our distribution subsidiary Edesur, showed a Ch$ 12,913 million drop in operating income, amounting Ch$ 22,114 million. The negative evolution of the company results is explained by higher operating costs derived from the country’s inflation rate, without the corresponding tariff increases. Increases in tariffs have not occurred due to delays by the Argentine Government in complying with certain obligations contained in Edesur’s agreement with the Argentine Government. This non-compliance primarily consists of failure to observe the cost monitoring mechanism (MMC, in its Spanish acronym) set forth in the agreement, which requires recognition of tariff adjustments every six months and the performance of an overall tariff revision (RTI, in its Spanish acronym). These delays have impacted negatively Edesur’s financial results.

Operating revenues decreased by Ch$ 6,463 million, 7,6% lower compared to same period last year. This is mainly explained by the decrease in energy sales revenues by Ch$ 5.417 million. The latter was partially offset by a Ch$ 4,151 million decrease in energy purchases.

Physical sales decreased by 3.0% reaching 4,398 GWh. The energy losses in this period were 10.6%, 0.1 p/p higher than 1Q 2012, and the number of customers increased by 34 thousand new customers, exceeding 2.4 million.

The net effect of translating the financial statements from Argentine pesos to Chilean pesos in both periods led to a 16.3% decrease in Chilean peso terms in March 2013, when compared to March 2012.

In Brazil, the operating income of our subsidiaries amounted to Ch$ 35,872 million, 9.8% lower than in same period of last year, when operating results amounted to Ch$ 39,770 million.

Cachoeira Dourada

The operating income of Cachoeira Dourada was Ch$ 18,036 million, 10.2% lower than March 2012. This is mainly explained by lower energy sales revenues of Ch$ 1,489 million, equivalent to 4.4% decrease, and an increase of 109.1% in energy purchases costs, due to an increase of 158.4% in average energy purchase price. This was partially offset by decreases of 26.0% and 23.4% in transportation costs and other operating cost respectively.

Physical sales showed a decrease of 14.2%, reaching 923 Gwh in the period.

The effect of converting these financial statements from Brazilian reals to Chilean pesos in both periods was a 14.5% reduction in Chilean peso terms in March 2013 when compared to March 2012.

Transmission

CIEN

Our transmission subsidiary, CIEN, showed a decrease in operating income of Ch$ 1,408 million, reaching Ch$ 8,490 million . This is explained by a decrease of 9.8% in energy sales revenues, partially offset by decreases of 16.3% and 9.7% in energy purchases costs and other operating costs respectively.

The effect of converting these financial statements from Brazilian reals to Chilean pesos in both periods was a 14.5% reduction in Chilean peso term in March 2013 when compared to March 2012.

Distribution

In Brazil, the operating income of our distribution subsidiaries amounted to Ch$ 66,332 million, which is 31.5% lower than that obtained in the first quarter of 2012.

Ampla

Ampla’s operating income amounted to Ch$ 45,048 million, which compared to same period in previous year represents a decrease of 4.2%. Operating revenues decreased by Ch$48,995 million, mainly due to lower energy sales revenues of Ch$ 47,766 million. This was partially offset by a Ch$ 39,767 million reduction in procurement and services costs, explained by Ch$ 26,905 million lower other procurement and services costs and a Ch$ 11,732 million reduction in energy purchases cost.

Physical sales grew by 2.9%, reaching 2,891 GWh. Energy losses increased by 0.5 p.p., from 19.4% to 19.9%. The number of Ampla’s customers increased by 81 thousand, thus exceeding 2.7 million customers.

The effect of converting these financial statements from Brazilian reals to Chilean pesos in both periods was a 14.5% reduction in Chilean peso term in March 2013 when compared to March 2012.

Chilean Operations

Operating income in Chile increased a 4.0% reaching Ch$ 33,833 million, while EBITDA increased by 10.1% totaling Ch$ 57,416 million as of March 2013. These better results in Chilean business were a consequence of lower energy purchases costs of Ch$ 38,941 million due to higher thermal generation due to Bocamina II plant commissioning (+683 GWh), lower fuel costs of Ch$ 14,346 million due to higher coal generation and lower LNG price, coupled with lower transportation costs of Ch$ 14,059 million.

The latter was partially offset by lower operating revenues of Ch$ 62,884 million because of a reduction of 19.6% in the average energy sale price related to less contracts indexed to a lower marginal cost. Additionally, physical sales decreased by 1.1% as a result of the end of some contracts with unregulatedcustomers customers. Finally, we booked higher payroll expenses of Ch$ 4,879 million due to a staff increase and inflation salaries readjustment.

Emgesa

The operating income of our generation subsidiary in Colombia amounted to Ch$ 83,839 million in this period, increasing by Ch$ 5,747 million or by the equivalent of 7.4% compared to first quarter 2012. This is mainly explained by a 13.5% increase in energy sales revenues, partially offset by higher energy purchases costs of Ch$ 14,715 million.

Physical energy sales grew by 2.6% reaching 3.833,0 GWh revisar and EBITDA in Emgesa grew by 7.6% in the period, reaching Ch$ 93,754 million

The net effect of translating the financial statements from Colombian pesos to Chilean pesos in both periods was negative, resulting in a 2.9% decline in Chilean peso term in March 2013, when compared to March 2012.

Edelnor

Our subsidiary Edelnor registered an operating income of Ch$ 16,413 million, 2.1% lower than in same period last year. This was mainly explained by an increase of 3.9% in procurement and services costs, due to a Ch$ 2,647 million increase in energy purchases cost, and a reduction of Ch$ 1,381 million, or 33.8%, in other operating revenues. The latter was partially offset by an increase of Ch$ 3,246 million in energy sales revenues.

Energy losses showed a reduction of 0.1 p/p when compared to the first quarter 2012,, reaching 8.1% in the current period. The number of customers expanded by 65 thousand, exceeding 1.2 million customers.

The net effect of translating the financial statements from Peruvian sol to Chilean peso in both periods resulted in a 0.7% increase in Chilean pesos in March 2013, when compared to March 2012.
