CERTAIN TERMS AND CONVENTIONS

Celulosa Arauco y Constitución S.A. is a corporation (sociedad anónima) organized under the laws of the Republic of Chile, and subject to certain rules applicable to Chilean public corporations (sociedades anónimas abiertas). Except where otherwise specified or the context otherwise requires, when we refer to the “Company,” “Arauco” or “we,” in this annual report, we mean Celulosa Arauco y Constitución S.A. and its consolidated subsidiaries. When we refer to “Chile,” we mean the Republic of Chile; when we refer to “Argentina,” we mean the Argentine Republic; when we refer to “Brazil,” we mean the Federative Republic of Brazil; when we refer to “the U.S.,” “U.S.A.,” or “the United States,” we mean the United States of America; and when we refer to “Uruguay,” we mean the Oriental Republic of Uruguay. All references to “tons” or “tonnes” are to metric tons (1,000 kilograms), which equal 2,204.7 pounds. One “hectare” equals 10,000 square meters or 2.471 acres. Discrepancies in any table between totals and the sums of the amounts listed are due to rounding.

Unless otherwise specified, all references to “$”, “U.S.$”, “U.S. dollars” or “dollars” are to United States dollars; references to “Chilean pesos” or “Ch$” are to Chilean pesos; references to “Argentine pesos” or “AR$” are to Argentine pesos; references to “Brazilian reals” or “R$” are to Brazilian reals; references to “€” or “euro” are to the euro, the single European currency established pursuant to the European Economic and Monetary Union; and references to “UF” are to Unidades de Fomento. The UF is a unit of account that is linked to, and adjusted daily to reflect changes in, the Chilean consumer price index reported by the Chilean National Institute of Statistics (Instituto Nacional de Estadísticas). As of December 31, 2012, one UF equaled U.S.$47.59 and Ch$22,840.75.

PRESENTATION OF FINANCIAL DATA

This report includes the audited consolidated financial statements of Arauco and our subsidiaries as of December 31, 2012 and 2011 and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2012, 2011 and 2010 (collectively, the “audited consolidated financial statements” or “financial statements”).

For your convenience, this annual report contains certain translations of Chilean peso amounts into U.S. dollars at specified rates. Unless otherwise indicated, the U.S. dollar equivalent for information in Chilean pesos is based on the observed exchange rate reported by Banco Central de Chile, the Central Bank of Chile, which we refer to as the “Central Bank of Chile” or the “Central Bank.” The Federal Reserve Bank of New York does not report a noon buying rate for Chilean pesos. On December 31, 2012, the observed exchange rate for Chilean pesos was Ch$479.96 to U.S.$1.00, and on April 29, 2013, the observed exchange rate was Ch$472.05 to U.S.$1.00. You should not construe these translations as representations that the Chilean peso amounts actually represent such dollar amounts or could be converted into U.S. dollars at the rates indicated or at any other rate. See “Exchange Rates.” Unless otherwise specified, references to the devaluation or the appreciation of the Chilean peso against the U.S dollar are in nominal terms (without adjusting for inflation) based on the observed exchange rates published by the Central Bank of Chile for the relevant period.

(2) Biological assets refer to our forests and long-standing trees.

(3) Includes capital expenditures in respect of property, plant and equipment and biological assets accrued for the period. Excludes acquisition of companies.

(4) Adjusted EBITDA is calculated by adding “fair value cost of timber harvested,” “exchange rate differences” and deducting “gain from changes in fair value of biological assets” to EBITDA. “Fair value cost of timber harvested” is a non-cash expense included in our cost of sales (as a component of raw materials) that represents the fair value of the wood harvested and sold from our own plantations, which is commonly excluded from the non-generally accepted accounting principles (non-GAAP) measures used by analysts to compare participants in our industry as it is a non-cash item (purchases of wood from third parties are cash expenses that are not included in “fair value cost of timber harvested”). “Gain from changes in fair value of biological assets” is a gain that does not represent a cash flow. We believe that Adjusted EBITDA provides investors with a useful supplemental indicator of the performance of our core business because (i) it cancels out the effects of fair value that are independent of the cost efficiency of our operating facilities and (ii) it excludes the effect of exchange rate differences, which are mainly derived from our debt instruments, and the effect of local costs as our functional currency is the U.S. dollar.

In evaluating the performance of Arauco, we believe that each of these non-GAAP financial measures should be considered together with and should not be considered in isolation, or as a substitute for, the analysis of our results as reported under IFRS. Some of the limitations of our non-GAAP financial measures are that EBIT, EBITDA and Adjusted EBITDA do not reflect: (i) our cash expenditures, or future requirements, for capital expenditures or contractual commitments; (ii) changes in, or cash requirements for, working capital needs; (iii) the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our outstanding debt.

Because all companies do not calculate EBIT, EBITDA or Adjusted EBITDA in the same manner, such measures as calculated by us may differ from such measures calculated by other companies. We compensate for these limitations by using EBIT, EBITDA and Adjusted EBITDA as supplemental measures of our performance and by relying primarily on our financial statements that have been prepared in accordance with IFRS.

The following table presents, for the periods indicated, the reconciliation of EBIT, EBITDA and Adjusted EBITDA to net income. Since the filing date of our annual report on Form 20-F for the year ended December 31, 2010, we have revised the methodology that we use to calculate our non-GAAP financial measures. Although we believe that the methodology used to calculate the non-GAAP financial measures included in our filings on Form 20-F prior to April 30, 2012 was compliant with the requirements of Form 20-F, we believe that the revised methodology provides readers of our annual report with an improved understanding of our operational performance from a core business perspective. However, as a result of the modifications to our calculation methodology, the reconciliation table set forth below and certain amounts included therein are not directly comparable to those included in filings prior to April 30, 2012.

(5) Average debt is calculated as the average between the beginning and the end of the applicable year.

(6) Total debt is calculated as the sum of other current financial liabilities and other non-current financial liabilities, less hedging instruments.

(7) Capitalization is calculated as total debt, including accrued interest, plus equity attributable to the parent company.

(8) For purposes of computing the ratio of earnings to fixed charges, earnings consist of income before income taxes plus fixed charges. Fixed charges consist of interest expense (including capitalized interest) and amortization of any discount and issuance costs related to our offerings of debt securities.

(9) Working capital is calculated by subtracting current liabilities from current assets.

FORWARD-LOOKING STATEMENTS

This annual report on Form 20-F contains words such as “believe,” “expect,” “anticipate” and similar expressions that identify forward-looking statements, which reflect our views about future events and financial performance. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. Such statements constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the United States Private Securities Litigation Reform Act of 1995, as amended.

Forward-looking statements involve inherent risks and uncertainties. These forward-looking statements are based on current plans, estimates and projections; therefore, readers should not place undue reliance on them. Actual results could differ materially from those projected in such forward-looking statements because of various factors that may be beyond our control, including but not limited to our ability to service our debt, fund our working capital requirements, comply with financial covenants in certain of our debt instruments, fund and implement our capital expenditure programs and maintain our relationships with customers, as well as a change in control, the effects on us from competition, future demand for forestry, panels and wood products in the Chilean, Argentine, Brazilian, Uruguayan, and North American export markets, international prices for forestry and wood products, the condition of our forests, possible shortages of energy, including electricity, the state of the Chilean and world economies and manufacturing industries, the relative value of the Chilean peso compared to other currencies, inflation, increases in interest rates, the effects of earthquakes, floods, tsunamis or other catastrophic events and changes in our regulatory environment, including our ability to comply with new or stricter environmental regulations and to resolve environmental liabilities. Forward-looking statements in this annual report speak only as of their dates, and we do not undertake any obligation to update or revise any of them, whether as a result of new information, future events or otherwise.

RISK FACTORS

We are subject to various changing economic, political, social and competitive conditions, particularly in our principal markets. Any of the following risks, if they actually occur, could materially and adversely affect our business, financial condition, results of operations and cash flows.

Risks Relating to Us and the Forestry Industry

Fluctuations in market price for our products could adversely affect our financial condition, results of operations and cash flows.

Prices for many of the products we sell can fluctuate significantly. The price of commodities such as pulp, panels and sawn timber has a high correlation with international prices. Consequently, the prices that we are able to charge for these products are highly dependent on prevailing international prices. Historically, such prices have been subject to substantial variation. For example, during the period from January 1, 2010 to December 31, 2012, the average price for Norscan bleached softwood kraft market pulp (pulp produced in Canada and Northern Europe sold to manufacturers of paper products delivered in Northern Europe, or NBSK), which is the benchmark for softwood bleached pulp, ranged from a low of U.S.$762.18 per tonne in September 2012 to a high of U.S.$1,023.1 per tonne in June 2011. During the last quarter of 2008 and the first quarter of 2009 there was a very rapid and significant reduction in the international prices of the products we sell and commodity prices in general as a result of the global financial crisis. In the second half of 2009, the international prices of the products we sell and commodity prices in general increased up to pre-financial crisis levels and continued at high levels in 2010 and the first half of 2011. In the second half of 2011, pulp prices started to decline. During 2012, prices for bleached hardwood kraft pulp increased steadily, but did not reach the 2011 average price. In 2012, the average price for NBSK continued to decline until September, increasing during the fourth quarter. The continuation of severe global economic conditions may continue to exert downward pressure on commodity prices, including the international prices of the products we sell, which could result in material and adverse declines in our revenues, results of operations and financial condition. We have no control over the factors that cause prices to change which include, among others:

• worldwide demand (which may be affected by a number of factors, including economic or political conditions in Asia, Latin America, North America and Europe);

• prevailing world prices, which historically have been subject to significant fluctuations over relatively short periods of time, depending on worldwide demand;

• world production capacity;

• the business strategies adopted by major integrated forestry, pulp and paper producers and other major producers; and

• the availability of substitutes.

In addition, the prices of many of the products we sell are correlated to some extent, and historical fluctuations in the price of one product have usually been accompanied by similar fluctuations in the prices of other products. If the price of one or more of the products that we sell were to decline significantly from current levels, it could have a material adverse effect on our revenues, results of operations and financial condition.

Worldwide competition in the markets for our products could adversely affect our business, financial condition, results of operations and cash flows.

We experience substantial worldwide competition in each of our geographical markets and in each of our product lines. Several of our competitors are larger than we are and have greater financial and other resources, which they could use to take steps that could materially and adversely affect our financial and competitive position. The pulp industry is sensitive to changes in industry capacity and producer inventories, as well as to cyclical changes in the world’s economies, all of which may significantly affect selling prices and, thereby, our profitability. One or more of these factors could materially and adversely affect our business, financial condition, results of operations and cash flows.

Global economic developments, and particularly economic developments in the Asian, European and U.S. economies, could have an adverse effect on the demand for our products, our financial condition, results of operations and cash flows.

The global economy, and in particular global industrial production, is the primary driver of demand for pulp, paper and wood products. Global industrial production dropped during the second half of 2008 and first half of 2009 due to the financial crisis and global economic conditions, resulting in a significant and widespread contraction in demand for pulp, paper and wood products. A continued decrease in the level of activity in either the domestic or the international markets within which we operate could adversely affect the demand and the price of our products and thus our cash flows and operational and financial results. Due to this downturn in global industrial production, our pulp segment experienced significant price declines in the last quarter of 2008 and the first quarter of 2009, which severely affected our results. In addition, the significant downturn in the home-building industry in the United States and Europe resulted in increased inventories of available new homes, significant declines in home prices, loss of home-equity values and loss of consumer confidence and demand. As a result of these events, our plywood and panel sales were adversely affected, continuing a downward trend both in volume and price across all markets. Our medium-density fiberboard molding sales also experienced a sharp decline in volume mainly due to the lower activity in the United States and Canadian construction markets. Our wood products segment, which is also highly dependent on the strength of the home-building industry, experienced decreases in its prices of and demand for its products. The decrease in demand of sawn timber products due primarily to the credit crisis and continued downturn in the real estate market in the United States resulted in our decision to close five sawmills in 2008 and 2009. These deteriorated market conditions also led us to close our Bossetti sawmill in Argentina in 2010.

Since late 2009, high levels of sovereign debt and insufficient public sector revenues have resulted in a European sovereign debt crisis. As of the date of this annual report, credit rating agencies have downgraded the credit ratings of many of the Eurozone governments, including Greece, Spain, Italy, Portugal and France, among others. During 2011 and the first quarter of 2012, the deepening of this crisis has caused a general economic downturn in Europe, which has negatively affected the banking and credit systems, employment and production. As a result, demand and prices for pulp and wood products have declined in the European market.

Export sales of our sawn timber products to Asia accounted for 35.8% of our sales revenue in 2012 compared to 38.6% in 2011 and 36.3% in 2010 and export sales of our wood products to North America accounted for 38.8% of our sales revenue in 2012 compared to 36.7% in 2011 and 39.7% in 2010. Our business, financial condition, results of operations and cash flows could be materially and adversely affected if the economic conditions in Asia, Europe, the United States and elsewhere abroad deteriorate, and if we are unable to reallocate our sawn timber and other products to other markets on equally beneficial terms, which could require us to recognize additional impairment charges.

We depend on free international trade as well as economic and other conditions in our principal export markets.

In 2012, export sales, defined as sales out of the country where our goods were produced, accounted for 66.1% of our total sales revenues. During this period, 47.8% of our export sales were to customers in Asia, 21.7% to customers in North America, 15.3% to customers in Europe, 9.9% to customers in Central and South America and 5.4% to customers in other countries. As a result, our results of operations and cash flows depend, to a significant degree, on economic, political and regulatory conditions in our principal export markets. Our ability to compete effectively in our export markets could be materially and adversely affected by a number of factors beyond our control, including deterioration in macroeconomic conditions, exchange rate volatility, government subsidies, and the imposition of increased tariffs or other trade barriers. If our ability to sell our products competitively in one or more of our principal export markets were impaired by any of these developments, it might be difficult to re-allocate our products to other markets on equally favorable terms and our business, financial condition, results of operations and cash flows might be adversely affected.

We are located in a seismic area that exposes our property in Chile to the risk of earthquakes and tsunamis, and we experienced significant business disruption and losses as a result of the February 27, 2010 earthquake.

Our properties in Chile are located in a seismic area that exposes our facilities, plants, equipment and inventories to the risk of earthquakes and even subsequent tsunamis in some areas. A significant earthquake or other catastrophic event could severely affect our ability to meet our production targets, satisfy customer demand and could require us to make unplanned capital expenditures, resulting in lower sales and having a material adverse effect on our financial results.

On February 27, 2010, an earthquake measured at a magnitude of 8.8 on the Richter scale, followed by a tsunami that affected the coast, occurred in the South-Central Region of Chile, an area where we maintain a substantial portion of our Chilean industrial operations. Immediately after the earthquake, all of our production units applied their contingency plans, which involved shutting down operations and evaluating the damage caused to each facility by the earthquake. As a result of the earthquake and the subsequent tsunami, our Mutrún sawmill was destroyed. The Mutrún sawmill represented 6% of our sawn timber production capacity in Chile.

The suspension of our operations in Chile resulted in significant asset impairment charges due to earthquake-related damage to property and inventories as well as a significant decrease in our sales volumes due to plant closures which had an adverse effect on our results of operations and cash flows. Our insurance policies provided coverage for damages to our property, plant, equipment and inventories and for business interruption caused by such damages up to an aggregate amount of U.S.$650 million, with a deductible of U.S.$3 million for property damage and a deductible of 21 days for business interruption. On November 15, 2011, we and the insurers accepted the final report of the insurance adjusters. In accordance with such final report, as of December 31, 2012, we received a total recovery of U.S.$532.0 million. We cannot assure you that we will not experience other suspensions or interruptions or unexpected damage to our property as a result of other earthquakes, aftershocks, tsunamis, any related repair and maintenance or other consequences associated with such events, any of which could have a material and adverse effect on our revenue, results of operations and financial condition.

The costs to comply with, and to address liabilities arising under, environmental laws and regulations could adversely affect our business, financial condition, results of operations and cash flows.

In each country where we have operations, we are subject to a wide range of national and local environmental laws and regulations concerning, among other matters, the preparation of environmental impact assessments for our projects, the protection of the environment and human health, the generation, storage, handling and disposal of waste, the discharge of pollutants and the remediation of contamination. As a forest products manufacturer, we generate air and water emissions and solid and hazardous wastes. These emissions and waste disposals are subject to limits or controls prescribed by law or by our operating permits, and we may be required to install or upgrade our pollution control equipment in order to meet these legal requirements. We have made, and expect to continue to make, expenditures to maintain compliance with environmental laws. Notwithstanding our policy to strictly comply with all requirements established by applicable environmental laws, any failure to comply with such environmental laws may result in civil, administrative or criminal fines or sanctions, claims for environmental damages, remediation obligations, the revocation of environmental authorizations or the temporary or permanent closure of facilities. Environmental regulations in Chile and other countries in which we operate have become increasingly stringent in recent years (for example, in connection with the approval and development of new projects), and this trend is likely to continue. Future changes in environmental laws, or in the application, interpretation or enforcement of those laws, including new or stricter requirements related to harvesting activities, air and water emissions and/or climate change regulations, could result in substantially increased capital, operating or compliance costs, impose conditions that restrict or limit our operations or otherwise adversely affect our business, financial condition, results of operations and cash flows. These changes could also limit the availability of our funds for other purposes, which could adversely affect our business, financial condition, results of operations and cash flows.

We have been subject to a number of environmental administrative and judicial proceedings in Chile, including proceedings related to the Valdivia Mill (2004-2005), the Arauco Mill (2004), the Nueva Aldea Complex (2004-2005) and the Licancel Mill (2007). As a result of these proceedings, we have been subject to monetary fines as well as sanctions, including orders to suspend or limit our operations. In the United States, our Moncure mill is

9

subject to an administrative proceeding by the North Carolina Department of Environment and Natural Resources. As of the date of this annual report, we are negotiating a settlement that may include a monetary fine and a requirement to replace certain emissions control equipment. Additional proceedings, enforcement actions or claims related to compliance with environmental requirements or alleged environmental damages may also be brought against us in the future. Any such proceedings or claims may have an adverse effect on our business, financial condition, results of operations and cash flows. See “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry—Environmental concerns led to the temporary suspension of our operations at the Valdivia Mill in 2005 and at the Licancel Mill in 2007, which adversely affected, and in the future may continue to adversely affect, our business, financial condition, results of operations and cash flows”.

Environmental concerns led to the temporary suspension of our operations at the Valdivia Mill in 2005 and at the Licancel Mill in 2007, which adversely affected, and in the future may continue to adversely affect, our business, financial condition, results of operations and cash flows.

Valdivia Mill

Our operations at the Valdivia Mill, an industrial development in the Province of Valdivia, have been subject to environmental scrutiny by Chilean environmental regulators and the Chilean public since the mill began its operations in 2004. A variety of concerns and claims have been raised regarding the mill’s potential environmental impacts in the area. Primarily, it has been alleged that the mill’s operations impacted the habitat of the nearby Carlos Anwandter Nature Sanctuary and contributed to the migration and death of black-neck swans living in the area. In connection with an environmental administrative proceeding, environmental regulators required us to temporarily suspend operations at the Valdivia Mill for approximately one month in January 2005.

In June 2005, we again suspended operations at the Valdivia Mill until certain technical and legal conditions could be clarified with the applicable regulatory authorities. We estimate this suspension resulted in a loss of sales of approximately U.S.$1.0 million per day and a loss of profits of approximately U.S.$250,000 per day. Pursuant to the decision of our board of directors, based on certain clarifications provided by the Environmental Regional Commission (Comisión Regional del Medio Ambiente), or COREMA, of the Tenth Region of Chile, the mill resumed operations in August 2005, after 64 days of suspended operations, at 80% of its authorized production capacity. In order to achieve the full production capacity authorized by applicable permits, the mill had to fulfill certain new requirements established by the COREMA. In January 2008, the COREMA authorized the Valdivia Mill to return to its annual authorized production capacity of 550,000 tonnes. The mill gradually increased its production over a four-month period starting in March 2008 and reached full capacity in June 2008.

In June 2007, we were required to submit to the COREMA of the Tenth Region of Chile an environmental impact study for the implementation of substantial technological improvements on the quality of the effluents generated by the Valdivia Mill. In June 2008, the COREMA approved that environmental impact study subject to certain conditions that, in our opinion, adversely affected the feasibility of the project. For such reason, we filed an appeal before the Directive Council (Consejo Directivo) of the National Environmental Commission (Comisión Nacional del Medio Ambiente), or CONAMA, challenging the conditions imposed by the COREMA. Our administrative appeal was partially accepted by the CONAMA, which upheld some of the conditions that we believed would adversely affect the feasibility of the project. Consequently, in September 2009, we presented another appeal in the relevant court. On December 5, 2012, the Environmental Evaluation Service of the Tenth Region of Chile authorized certain changes to the project based on the implementation of certain technological improvements. On November 9, 2012, we withdrew our appeal. The court approved the withdrawal on November 29, 2012.

Until October 2007, our Valdivia Mill was under the jurisdiction of the COREMA of the Tenth Region of Chile, but due to a change in legislation creating two new administrative regions in Chile, our Valdivia Mill became subject to the jurisdiction of the COREMA of the Fourteenth Region of Chile. In February 2009, as previously required by the COREMA of the Tenth Region of Chile, we submitted to the COREMA of the Fourteenth Region of Chile an environmental impact study for the construction of a pipeline to discharge the Valdivia Mill’s wastewater in the Pacific Ocean near Punta Maiquillahue, complying with the requirement that such wastewater be discharged in a body of water other than the Cruces River, the Carlos Anwandter Nature Sanctuary or their respective sources. In February 2010, through Exempt Resolution No. 27/2010, the COREMA approved this environmental impact

10

study subject to additional conditions, certain of which we challenged before the Directive Council primarily because they would have prohibited the discharge of wastewater into the Cruces River under any circumstance, including emergencies. On October 23, 2012, the Committee of Ministers passed Exempt Resolution No. 1052, which upheld in part our appeal in permitting the discharge into the Cruces River upon the occurrence of certain contingencies that may affect the normal functioning of the conduction system and/or outfall, including bombings or sabotage, natural disasters, or accidents caused by third parties. On March 29, 2010, two Chilean individuals filed a reclamation action (recurso de participación ciudadana) before the COREMA of the Fourteenth Region of Chile, challenging Exempt Resolution No. 27/2010. As of the date of this annual report, the Committee of Ministers has not issued a resolution concerning this action.

Resolution of our proceeding with the CONAMA regarding the resolutions that approved the environmental impact study of the pipeline, as well as the construction and operation of the pipeline, are each subject to many environmental, regulatory, engineering and political uncertainties. As a result, we cannot provide any assurances that the project will be finally approved as requested or completed. If either the request for the necessary permits for the construction of the pipeline is rejected, or the installation of the pipeline is delayed for reasons attributable to us, we may face sanctions that include warnings, fines or the revocation of the Valdivia Mill’s environmental permit for operation. Alternatively, if any rejection or delays are attributable to reasons beyond our control, we believe that the environmental authorities should extend the applicable deadlines. However, we can provide no assurances that any deadline extensions would be granted, even if we comply with all the requirements that may be set forth by those authorities. See “Item 4. Information on the Company—Description of Business—Pulp—Pulp mills—Chile—Valdivia Mill” and “Item 8. Financial Information—Legal Proceedings.”

The suspension of operations at the Valdivia Mill in 2005 adversely affected our business, financial condition, results of operations and cash flows. Any future suspension of operations at the Valdivia Mill or at any other of our significant operating plants can be expected to have similar adverse effects. We offer no assurance that the Valdivia Mill, or our other mills, will be able to operate without further interruption. See “Item 8. Financial Information—Legal Proceedings.”

Licancel Mill

In June 2007, our operations at the Licancel Mill, a pulp mill located in the Seventh Region of Chile, became subject to environmental scrutiny by Chilean environmental regulators and the public due to the death of fish in the Mataquito River, approximately 15 kilometers downstream of the mill. As a result, in June 2007 Chilean authorities, including certain public health authorities and the Superintendencia de Servicios Sanitarios (Sanitary Services Superintendency), required that we suspend activities at the Licancel Mill and that we suspend any further discharges into the river. In 2007, we invested U.S.$8 million in a new effluent treatment system for the Licancel Mill, and the mill resumed operations during January 2008. On September 7, 2007, the National Defense Council instituted a civil lawsuit seeking reparations, damages and indemnification from us for environmental harm allegedly caused by the Licancel Mill. The National Defense Council agreed to terminate this lawsuit pursuant to an agreement with Arauco dated January 29, 2010. Nevertheless, we can offer no assurance that the Licancel Mill will be able to operate without further interruptions. Any future suspension of operations at the Licancel Mill would adversely affect our business, financial condition, results of operations and cash flows. We estimate that the suspension of operations at the Licancel Mill resulted in a total loss of profits of U.S.$24 million.

We are subject to legal proceedings related to our mills which could adversely affect our business, financial condition, results of operations and cash flows.

In April 2005, the National Defense Council (Consejo de Defensa del Estado), the Chilean national agency that institutes legal proceedings on behalf of the Chilean government, instituted a civil lawsuit seeking reparations, damages and indemnification from us for environmental harm allegedly caused by the effluent discharges from our Valdivia Mill. The National Defense Council has not quantified the damages it is seeking in connection with the Valdivia Mill lawsuit.

The Valdivia Mill lawsuit remains under review by the court as of the date of this annual report. If the result of the Valdivia Mill lawsuit is unfavorable to us, we may be required to invest a significant amount of funds and/or take other actions to repair any environmental harm a court determines we have caused, which could materially and adversely affect our business, financial condition, results of operations and cash flows. We cannot predict the outcome or impact of this lawsuit or when it may be resolved.

11

Since the end of 2004, we have been subject to various criminal proceedings relating to alleged violations of several environmental laws in Chile, each of which has been either terminated or abandoned by the prosecutor (decisión de no perseverar) as of the date of this annual report. See “Item 8. Financial Information—Legal Proceedings.” The commencement of similar criminal proceedings against Arauco at any time in the future could adversely affect some of our mills. We can neither predict the likelihood that we will face such similar proceedings in the future, nor the likely outcome or impact of any such proceedings.

We are also subject to certain other civil and administrative proceedings relating to our mills. We cannot assure you that, as a result of such proceedings, our mills will be able to operate without interruption. Any such interruption, or unexpected costs to resolve such proceedings, could have a material and adverse effect on our business, financial condition, results of operations and cash flows.

We are subject to a substantial tax claim in Argentina.

On December 14, 2007, the Administración Federal de Ingresos Públicos (“AFIP”), Argentina’s internal revenue service, notified our Argentine subsidiary, Alto Paraná S.A. (“Alto Paraná”), of a claim for unpaid taxes for fiscal years 2002, 2003 and 2004 in the aggregate amount of AR$418 million (or approximately U.S.$105 million) including principal, interest and penalties accrued through such date, arising from a dispute regarding certain income tax deductions (related to debt issued by Alto Paraná in 2001 and repaid in 2007) taken by Alto Paraná and rejected by the AFIP. On February 8, 2010, the Tribunal Fiscal de la Nación, Argentina’s tax court, issued an administrative ruling requiring that Alto Paraná pay the AFIP’s claim in full.

Alto Paraná appealed this administrative ruling to the Court of Appeals, in addition to filing an injunctive action requesting that the court stay Alto Paraná’s payment obligation until resolution of its pending appeal. On May 13, 2010, the Court of Appeals granted an injunction of Alto Paraná’s payment obligation in exchange for the posting of a surety bond in the amount of AR$633.6 million (or approximately U.S.$129 million). On December 28, 2012, the Court of Appeals dismissed Alto Paraná’s appeal. Alto Paraná appealed this decision before the Argentine Supreme Court of Justice (“Supreme Court”). The appeal, once conceded, will suspend the execution of the decision ruled by the Court of Appeals.

We have not established any reserve in respect of this contingency and can offer no assurance that the Supreme Court will issue a ruling favorable to us. If the Supreme Court upholds the decision of the Court of Appeals, Alto Paraná will be required to satisfy the above-mentioned claim, an outcome that would have an adverse effect on our financial condition and results of operations. For more information regarding this claim or any other substantial tax claim in Argentina, see “Item 8. Financial Information—Legal Proceedings—Tax Litigation in Argentina.”

Our ability to access local and international credit or capital markets may be restricted at a time when we need financing, which could have a material adverse effect on our flexibility to react to changing economic and business conditions.

As of December 31, 2012, we had approximately U.S.$4,400.5 million of outstanding indebtedness. See “Management’s discussion and analysis of financial condition and results of operations—Liquidity and capital resources—Contractual obligations.” In light of the current economic environment, we may be unable to access, or we may be restricted in accessing, credit and capital markets to satisfy our financing needs, or we may not be able to refinance our existing indebtedness on terms that are favorable to us or at all. If we are unable to refinance our indebtedness as it becomes due, or if we refinance such indebtedness on terms that are not favorable to us, our business, results of operations and financial condition could be materially and adversely affected.

12

Material disruptions at any of our manufacturing, mills processing or remanufacturing facilities could negatively impact our financial results.

A material disruption at any of our manufacturing, processing or remanufacturing facilities could prevent us from satisfying customer demand for our products, meeting our production targets and/or require us to make unplanned capital expenditures, resulting in lower sales, which would have a negative effect on our financial results. Our Chilean facilities are located in a region known for seismic activity that exposes our facilities in Chile to the risk of earthquakes and in some areas, to subsequent tsunamis. In addition, our facilities (or any of our machines within an otherwise operational facility) could cease operations unexpectedly due to a number of events, including:

• unscheduled maintenance outages;

• prolonged power failures;

• an equipment failure;

• fires, floods, hurricanes or other adverse weather;

• disruptions in the transportation infrastructure, including roads, bridges, railroad tracks and tunnels;

• a chemical spill or release;

• explosion of a boiler;

• the effect of a drought or reduced rainfall on its water supply;

• labor difficulties;

• terrorism or threats of terrorism;

• domestic and international laws and regulations applicable to our Company and our business partners, including joint venture partners, around the world; and

• other operating problems.

Disease or fire could affect our forests and manufacturing processes and, in turn, adversely affect our business, financial condition, results of operations and cash flows.

Our operations are subject to various risks affecting our forests and manufacturing facilities, including disease and fire. Although to date certain pests and diseases afflicting radiata or taeda pine plantations in other parts of the world have not significantly affected the forestry industries in Chile, Argentina, Brazil and Uruguay, these pests or diseases do migrate and may significantly affect the forestries industries in Chile, Argentina, Brazil or Uruguay in the future. Similarly, forest fires are always a risk, particularly during low rainfall conditions. We do not maintain insurance against pests, diseases or, in certain areas, fires that could affect our forests, and as a result our business, financial condition, results of operations and cash flows could be adversely affected if any of these risks were realized.

Commencing on December 31, 2011, wildfires, exacerbated by high temperatures and strong winds, broke out in the Eighth Region of Chile. As a result, the fires destroyed our Nueva Aldea plywood mill and approximately 8,200 hectares of our forest plantations. The affected forest plantations represent approximately 0.8% of our total forest plantations. Our Nueva Aldea plywood mill, which represented a cash investment of approximately U.S.$110 million, had an annual production capacity of 450,000 cubic meters, representing approximately 14.2% of our total panel production capacity. Although the plywood mill at Nueva Aldea and our forest plantations are insured, our insurance is subject to deductibles and caps, including a 15-day deductible relating to our business interruption insurance for the Nueva Aldea plywood mill.

13

Climate change may negatively affect our business, financial condition, results of operations and cash flows.

A growing number of scientists, environmentalists, international organizations, regulators and other commentators maintain that global climate change has contributed, and will continue to contribute, to the increasing unpredictability, frequency and severity of natural disasters (including, but not limited to, hurricanes, droughts, tornadoes, freezes, other storms and fires) in certain parts of the world. As a result, a number of legal and regulatory measures as well as social initiatives have been introduced in numerous countries in an effort to reduce carbon dioxide and other greenhouse gas emissions, which some argue to be substantial contributors to global climate change. Such reductions in greenhouse gas emissions could result in increased energy, transportation and raw material costs and may require us to make additional investments in facilities and equipment. In addition, our plantations are located in regions which have ideal climatic conditions for a short growing cycle. Any climate changes that negatively affect such favorable climate conditions in central or southern Chile or in any region in which we benefit from favorable climate conditions could adversely affect the growth rate and quality of our plantations, or our production costs. Although we cannot predict the impact of changing global climate conditions, if any, nor can we predict the impact of legal, regulatory and social responses to concerns about global climate change, any such occurrences may negatively affect our business, financial condition, results of operations and cash flows.

Our operations could be adversely affected by labor disputes.

Approximately 19.3% of our employees in Chile, 46.9% of our employees in Argentina, 10.7% of our employees in Brazil and none of our employees in the United States or Canada were unionized as of December 31, 2012. In the past, certain work slowdowns, stoppages and other labor-related disruptions have adversely affected our operations.

In Chile we experienced (i) a four-day work stoppage in July 2012 at our Horcones Panel Mill located in Arauco, during which production resumed partially after the second day, (ii) a 10-day work stoppage in November 2009 at our Constitución, Arauco, Nueva Aldea, Horcones and Trupán-Cholguán complexes, (iii) a three-day work stoppage in September 2009 at our Constitución, Valdivia, Arauco, Nueva Aldea, Horcones and Trupán-Cholguán complexes and (iv) a six-day work stoppage in May 2007 at our Horcones complex (which includes the Arauco pulp mill, a panel plant and two sawmills), each of which was caused by the employees of our third party forestry contractors at each of the respective facilities.

Our Argentinean operations did not experience any work stoppages in 2012. However in 2011 and 2010 we experienced (i) a 3-day stoppage at Alto Paraná’s chemical mill in March 2011, as a result of a strike by the chemical union and (ii) a 4-day stoppage at Alto Paraná’s pulp mill in September 2010, as a result of a strike by the pulp union, but these strikes were limited to two hours per shift and did not materially affect operations. In January 2008, Alto Paraná’s chemical mill in Argentina experienced three days of work stoppage, but these strikes were limited to two hours per shift and did not materially affect operations. In addition, in January and February 2007, we experienced (i) a 12-day stoppage at our Zárate mill due to a dispute arising between the local chemical and timber unions with regard to the representation of their workers at the mill and (ii) a six-day suspension of operations at the Alto Paraná’s pulp mill as a result of a strike by a group of approximately 150 power saw operators.

Our Brazilian operations have not experienced any work stoppages in the last five years.

In September 2011, we experienced a 12-day work stoppage of construction at our Montes del Plata joint venture in Uruguay.

Our Canadian and American operations have not experienced any work stoppages in 2012.

Our principal collective-bargaining agreements in Chile are scheduled to expire during 2013, 2014 and 2015. We cannot assure you that a work slowdown, or a work stoppage or strike, will not occur prior to or upon the expiration of our labor agreements, and we are unable to estimate the adverse effect of any such work slowdown, stoppage or strike on our sales.

14

In addition, we depend to a significant extent on employees of contractors to which we outsource a wide range of services including management of certain of our plantations and transportation of raw materials and products. On July 1, 2012, we commenced the process of insourcing the operation of 13 sawn timber industrial facilities, which had previously been managed by third-party companies. In the process, we hired 2,900 employees of these third-party companies. As of December 31, 2012, we had contracts with approximately 1,087 contractors, who employed approximately 27,031 employees. Under Chilean and Brazilian labor legislation, we are secondarily liable for the payment of labor and the social security obligations owed to employees of our contractors. In Chile, in the event that we do not exercise the rights granted to us by the labor laws regarding the supervision of our contractors in their compliance of their labor and social security obligations, then our responsibility is elevated from secondary to joint and several, thus enabling an employee of a contractor to bring a claim relating to these obligations against both the contractor and to us, as the party hiring such contractor, although the contractor would remain primarily liable for such obligations. Generally, we are also responsible for the health and safety conditions of the contractors’ workers and are obligated to ensure that the contractors comply with all obligations related to such conditions while such workers are performing activities for us within our corporate purpose.

In Argentina, substantially similar joint liability rules apply to a principal and its contractors. In addition, a new national rural labor law, Law 26,727, promulgated on December 28, 2011 but which became fully operational after publication of certain relevant regulations, permits contractor employees under forestry contracts to bring actions directly against the principal to whom the employees’ services are being provided, instead of requiring them to bring actions against the contractor. For work or services related to the ordinary production process of a principal, the law provides that an employment relationship exists between the principal and the employee of the contractor. As a result of the foregoing, we may be affected by future strikes, work slowdowns, stoppages or other labor-related developments in the various countries in which we operate, including such developments attributable to employees of contractors performing outsourced services, and such strikes, slowdowns, stoppages or other developments could have a material adverse effect on our business, financial condition, results of operations or prospects.

Risks Relating to Chile

Adverse changes in Chile’s political and economic conditions could directly impact our business and the market price of our securities.

As of December 31, 2012, 73.6% of our property, plant and equipment and forest assets were directly owned by the Company and our Chilean subsidiaries, and in 2012, 73.3% of our revenues were attributable to our Chilean operations. Accordingly, our business, financial condition, results of operations and cash flows depend, to a considerable extent, upon economic conditions in Chile. Future changes in the Chilean economy could adversely affect our business, financial condition, results of operations and cash flows and may impair our ability to proceed with our strategic plan of business. In addition, such changes may impact the market price of our securities.

The Chilean government has exercised and continues to exercise a substantial influence over many aspects of the economy. We have no control over and cannot predict how government intervention and policies will affect the Chilean economy or, directly and indirectly, our operations and revenues. Our operations and financial condition and the market price of our securities may be adversely affected by changes in policies involving exchange controls, taxation and other matters.

Chile has different corporate disclosure standards from those with which you may be familiar in the United States, and Chile’s securities laws may not afford you the same protections as U.S. securities laws.

The securities disclosure requirements applicable to certain foreign private issuers differ from those applicable to issuers domiciled in the United States in some important respects. Accordingly, the information about us available to you will not be the same as the information disclosed by a U.S. company required to file reports with the U.S. Securities and Exchange Commission.

In addition, although Chilean law imposes restrictions on insider trading and price manipulation, applicable Chilean securities laws and regulations are different from those in the United States, and some investors protections available in the United States may not be available in the same form, or at all, in Chile.

Inflation in Chile may disrupt our business and have an adverse effect on our business, results of operations, financial condition and cash flows.

Chile has experienced high rates of inflation in the past. The annual rates of inflation (as measured by changes in the consumer price index and as reported by the Chilean National Institute of Statistics) in 2008, 2009, 2010, 2011 and 2012 were 7.1%, -1.4%, 3.0%, 4.4% and 1.5% respectively. High levels of inflation in Chile could adversely affect the Chilean economy and have a material adverse effect on our revenues, results of operations, financial condition and cash flows. Changes in the rate of inflation in Chile could continue in the future. Due to the competitive pressures we face in each of our product lines, we may not be able to increase prices in lock-step with inflation, which could materially and adversely affect our revenues, results of operations, financial and cash flows.

Currency fluctuations may have a negative effect on our financial results.

The Chilean peso has been subject to depreciations and appreciations in the past and may be subject to significant fluctuations in the future. We transact a significant portion of our business in U.S. dollars, and the U.S. dollar is the currency of the primary economic environment in which we operate. A significant portion of our operating costs, however, are denominated in Chilean pesos. An increase in the Chilean peso/U.S. dollar exchange rate increases our Chilean peso-denominated costs.

In addition, as an international company operating in Chile and several other countries, we transact a portion of our business and have assets and liabilities in Chilean pesos and other non-U.S. dollar currencies, such as the Argentine peso, the Uruguayan peso, the Brazilian real, the Colombian peso, Mexican peso and the Canadian dollar, among others. To the extent that the Chilean peso depreciates against the U.S. dollar, our domestic sales revenues may be adversely affected when expressed in U.S. dollars. The same effects may occur for our domestic sales in Argentina, Brazil and Canada for revenues related to products sold in each of the respective local currencies. As a result, fluctuations in the exchange rates of such foreign currencies to the U.S. dollar may have a material adverse effect on our business, results of operations, financial condition and cash flows.

Risks Relating to Argentina

The economic conditions in Argentina may adversely affect our financial condition, results of operations and cash flows.

As of December 31, 2012, 10.4% of our property, plant and equipment and forest assets were owned by our Argentinean subsidiaries, and in 2012, 11.1% of our revenues were attributable to our Argentine operations. The financial condition and results of our Argentine operations, including the ability of our Argentine subsidiary Alto Paraná to raise capital, depend, to a certain extent, upon economic conditions prevailing in Argentina. See “Item 4. Information on the Company—Description of Business—History.”

From 1998 to 2002, the Argentine economy experienced an economic recession marked by reduced levels of consumption and investment and an elevated unemployment rate. The Argentine gross domestic product, or GDP, decreased by 0.8% in 2000, 4.0% in 2001 and 10.9% in 2002. Since 2003, the Argentine GDP increased by 8.8% in 2003, 9.0% in 2004, 9.2% in 2005, 8.5% in 2006, 8.7% in 2007 and 6.8% in 2008. Although in 2009, Argentina’s GDP growth slowed to 0.9% as a result of the global financial crisis, in 2010 it increased to 9.2%, in 2011 it decreased to 8.9%, and in 2012 it decreased to 1.9%. Depending on the future development of the economy of Argentina, over which we have no control, our business, financial condition, results of operations and cash flows could be adversely affected.

In addition, there are many aspects of the Argentine economy that could adversely affect our operations, including, among others, inflation, interest rates, foreign exchange controls and taxes. We have no control over and cannot predict how the Argentine economy could affect our operations and revenues in Argentina.

16

Changes in the Argentine economy may impair the ability of Alto Paraná, our Argentine subsidiary, to meet its obligations and transfer money abroad.

We guarantee a portion of Alto Paraná’s debt. We may be required to fulfill our obligation under our guarantees if Alto Paraná’s ability to transfer funds abroad to service such debt is restricted. For a description of Alto Paraná’s debt which we guarantee see “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources.”

Since 2001, there have been a number of monetary and currency exchange control measures implemented in Argentina, which have included the obligation to repatriate foreign currency earned abroad and tight restrictions on transferring funds abroad, with certain exceptions for authorized transactions. Although current restrictions have not materially affected Alto Paraná’s business, financial condition, results of operations and cash flows, including its ability to service its debt, if in the future such payments are restricted, such restriction would be an obstacle to Alto Paraná’s ability to transfer money abroad, which may negatively affect its financial condition, results of operations and cash flows.

Risks Relating to Brazil

Economic conditions in Brazil may have a direct impact on our business, financial condition, results of operations and cash flows.

As of December 31, 2012, 11.8% of our property, plant and equipment and forest assets were owned by our Brazilian subsidiaries, and in 2012, 9.8% of our revenues were attributable to our Brazilian operations.

During the first quarter of 2005, we acquired all of the shares of capital stock of LD Forest Products S.A. and of Placas do Paraná S.A., or Placas do Paraná, in Brazil, as well as 50% of the shares of capital stock of Dynea Brasil S.A., or Dynea Brasil, in Brazil. In April 2010, our subsidiary Arauco do Brasil S.A. acquired the other 50% of the shares of Dynea Brasil. As a result of this acquisition, we own 100% of the shares of Dynea Brasil.

In September 2007, our subsidiaries Placas do Paraná S.A. and Arauco Florestal S.A. entered into an agreement for the joint ownership of land with Stora Enso Oyj, or Stora Enso, a Finnish-Swedish multinational corporation. Pursuant to the agreement, we acquired 80% of the shares in Stora Enso Arapoti Empreendimentos Agrícolas S.A., now Arauco Florestal Arapoti S.A., which owns 50,000 hectares of land, including 25,000 hectares of pine and 5,000 hectares of eucalyptus plantations; 20% of the shares remain in Stora Enso Arapoti Indústria de Papel S.A., which owns a paper mill with an annual production capacity of 205,000 tons of light weight coated paper; and 100% of the shares of Stora Enso Arapoti Serraria Ltda., which owns a sawmill with an annual production capacity of 150,000 cubic meters per year. In August 2009, we acquired, through our Brazilian subsidiary Placas do Paraná, Tafisa Brasil S.A., or Tafisa Brasil, which has a panel production facility located in the city of Pien, Brazil, with an annual total installed capacity of 725,000 cubic meters, and which includes two production lines producing medium density fiberboard (MDF) and one production line producing particleboard. The facility also has added-value lines to produce products for the construction and furniture industries.

On November 17, 2011, Centaurus Holdings S.A., a Brazilian company that is 51% owned by Klabin S.A. and 49% by our subsidiary Arauco Forest Brasil S.A., acquired the quotas of Florestal Vale do Corisco Ltda., which has 107,000 hectares of land in the Brazilian state of Paraná. The total purchase price for the proposed transaction was U.S.$473.5 million, of which we paid 49%. We received antitrust approval of this transaction from Brazilian authorities on July 18, 2012.

As a result of the foregoing, to a certain extent, our business, financial condition, results of operations and cash flows will be dependent on economic conditions in Brazil.

The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy. Brazilian political and economic conditions have a direct impact on our business.

The Brazilian government has intervened in the Brazilian economy and, occasionally, has made drastic changes in policy and regulations. The Brazilian government’s actions to control inflation and other policies and

17

regulations have often involved, among other measures, wage and price controls, currency devaluations, capital controls and limits on imports. The business, financial condition, results of operations and cash flows of our Brazilian subsidiaries may be adversely affected by such matters, changes in policy or regulation involving tariffs and exchange controls, as well as by factors such as:

• currency fluctuations;

• real estate ownership restrictions;

• inflation;

• social instability;

• price instability;

• interest rates;

• liquidity of domestic capital and lending markets;

• tax policy; and

• other political, diplomatic, social and economic developments in or affecting Brazil.

The Brazilian government’s actions have had and may continue to have a material effect on private sector entities, including our operations in Brazil. We have no control over and cannot predict how government intervention and policies will affect the Brazilian economy or, directly and indirectly, our operations and revenues.

Inflation and efforts by the Brazilian government to combat inflation may contribute significantly to economic uncertainty in Brazil and could harm the business of our Brazilian subsidiaries.

Brazil has, in the past, experienced high rates of inflation. More recently, Brazil’s rates of inflation were 5.9% in 2008, 4.3% in 2009, 5.9% in 2010, 6.5% in 2011 and 5.8% in 2012, as measured by the Brazilian consumer price index (Índice de Preços ao Consumidor-Amplo). In the past, inflation, governmental measures to combat inflation and public speculation about possible future actions have had significant negative effects on the Brazilian economy. Certain future measures, if taken by the Brazilian government, including interest rate increases, intervention in the foreign exchange market and actions to adjust or fix the value of the real may trigger increases in inflation, and consequently, have adverse economic impacts on the business, financial condition, results of operations and cash flows of our Brazilian subsidiaries could suffer.

Fluctuations in the value of Brazil’s currency against the value of the U.S. dollar may result in uncertainty in the Brazilian economy and the Brazilian securities market, which may adversely affect the financial condition, results of operations and cash flows of our recently acquired Brazilian subsidiaries.

The Brazilian real has historically suffered frequent devaluation. In the past, the Brazilian government has implemented various economic plans and exchange rate policies, including sudden devaluations, periodic mini-devaluations during which the frequency of adjustments has ranged from daily to monthly, floating exchange rate systems, exchange controls and dual exchange rate markets. Although over long periods, depreciation of the real generally is correlated with the differential in the inflation rate in Brazil versus the inflation rate in the United States, depreciation over shorter periods has resulted in significant fluctuations in the exchange rate between the real and the U.S. dollar and other currencies.

For example, the real depreciated by 11.2% against the U.S. dollar in 2011, and depreciated by 8.2% in 2012. The exchange rate between the real and the U.S. dollar may continue to fluctuate and may rise or decline substantially from current levels.

18

Devaluation of the Brazilian real and currency instability may adversely affect our results of operation and financial condition in terms of U.S. dollars and could adversely affect the ability of our Brazilian subsidiaries to meet their foreign currency obligations in the future and could result in a monetary loss relating to these obligations.

Risks Relating to Uruguay

Economic conditions in Uruguay, and/or the failure of our Montes del Plata joint venture and its affiliates to service their debt, may have a direct impact on our financial condition, results of operations and cash flows.

We have made significant investments in Uruguay and we may make additional investments in Uruguay in the future. As a result, our financial condition and results of operations may consequently depend, to a certain extent, on political and economic conditions in Uruguay. Certain future actions by the Uruguayan government, including, among others, actions with respect to inflation, interest rates, foreign exchange controls and taxes, could have a material adverse effect on our operations in Uruguay.

In September 2009, we executed a series of agreements, pursuant to which we and Stora Enso agreed to combine our respective assets in Uruguay in a 50%-50% joint venture. As a consequence of this transaction, we and Stora Enso equally own and control all assets that we and Stora Enso previously owned in Uruguay, which includes approximately 74,000 hectares previously owned by Stora Enso (including 17,300 hectares which are already planted with forests) and approximately 39,000 hectares previously owned by us (of which 27,400 are already planted with forests).

In addition, in October 2009, we and Stora Enso acquired in equal parts the Uruguayan subsidiaries of the Spanish company Grupo Empresarial ENCE, or “ENCE”. The principal assets of these companies consist of approximately 130,000 hectares of land, of which approximately 73,000 have forestry plantations, approximately 6,000 hectares under agreements with third parties and one industrial site, certain environmental permits for the construction of a pulp mill, a river terminal and one nursery. We own and operate these acquired assets jointly with Stora Enso as part of our Montes del Plata joint venture. The aggregate value of the assets acquired as a result of this transaction was U.S.$335 million, of which we paid 50% (or approximately U.S.$167.5 million).

On January 18, 2011, Arauco and Stora Enso agreed to carry out the construction of a state of the art pulp mill with an annual guaranteed capacity of 1.3 million tons, a port and a power producing unit based on renewable sources, all located in Punta Pereira, department of Colonia, Uruguay. The total estimated investment is U.S.$2,000.0 million.

The project is being financed approximately 40% by Arauco and Stora Enso on an equal basis, pursuant to their Montes del Plata joint venture, and 60% by long-term debt financing. The debt financing, incurred on September 29, 2011, includes a loan agreement among Celulosa y Energía Punta Pereira S.A. and Zona Franca Punta Pereira S.A., each an Uruguayan affiliate of the Montes del Plata joint venture, and Banco Interamericano de Desarrollo, known as the “IDB Facility Agreement,” of up to U.S.$454,000,000, and an export credit agency agreement, known as the “Finnvera Guaranteed Facility Agreement” of up to U.S.$900,000,000. Arauco agreed to guarantee 50% of this debt. As of December 31, 2012, U.S.$1,111.9 million of an aggregate maximum available amount of U.S.$1,354.0 million was outstanding under both facilities. If Celulosa y Energía Punta Pereira or Zona Franca Punta Pereira default under any or both of these facilities, we may be required to make a payment on their behalf or to assume on our balance sheet the portion of their debt that we guarantee, an outcome that may materially adversely affect us. For more information regarding these guarantees, see “Item 5. Operating and Financial Review and Prospects—Off-Balance Sheet Arrangements.”

Risks Relating to the United States

Economic conditions in the United States may have a direct impact on our business, financial condition, results of operations and cash flows.

As of December 31, 2012, 0.9% of our property, plant and equipment and forest assets were owned by our U.S. subsidiaries, and in 2012, 2.7% of our revenues were attributable to our U.S. operations.

On December 29, 2011, Arauco Panels USA, one of our U.S. subsidiaries, entered into an asset purchase agreement to acquire an industrial facility in Moncure, North Carolina. The facility includes medium-density fiberboard (MDF) and high-density fiberboard (HDF) production lines with annual production capacity of up to 330,000 cubic meters, a particleboard production line with annual production capacity of up to 270,000 cubic meters and two melamine product production lines. On June 7, 2012, we entered into a share purchase agreement to acquire 100% of the shares of Flakeboard Company Limited (“Flakeboard”), a Canadian company, for a total purchase price of U.S.$242.5 million. In addition to two panel mills in Canada, Flakeboard owns and operates five

19

panel mills in the U.S. with an aggregate annual production capacity of MDF panels of 699,000 cubic meters, an annual production capacity of 938,000 cubic meters of PB, and an annual production capacity of 264,000 cubic meters of melamine. The acquisition of Flakeboard was completed in September 2012.

As a result of the foregoing, to a certain extent, our business, financial condition, results of operations and cash flows will be dependent on economic conditions in the United States.

Risks Relating to Canada

Economic conditions in Canada may have a direct impact on our business, financial condition, results of operations and cash flows.

As of December 31, 2012, 3.3% of our property, plant and equipment and forest assets were owned by our Canadian subsidiaries, and in 2012, 3.1% of our revenues were attributable to our Canadian operations.

As a result of our acquisition of Flakeboard, in addition to the abovementioned five panel mills in the U.S., we own and operate two panel mills in Canada with an aggregate annual production capacity 470,000 cubic meters of MDF panels, an annual production capacity of 216,000 cubic meters of PB, and an annual production capacity of 370,000 cubic meters of melamine.

As a result of the foregoing, to a certain extent, our business, financial condition, results of operations and cash flows will be dependent on economic conditions in Canada.

Risks Relating to Other Markets

Our business, earnings and prospects may be adversely affected by developments in other countries that are beyond our control.

Our business, financial condition, results of operations and cash flows depend, to a large extent, on the level of economic activity, government and foreign exchange policies and political and economic developments in our principal export markets. 94.4% of our total pulp sales in 2011 and 93.3% in 2012, as well as 54.9% in 2011 and 49.2% in 2012 of our total sales of forestry, wood and panel products were attributable to exports, principally to customers in Asia, the Americas and Western Europe. Our business, earnings and prospects, as well as our financial condition, results of operations, cash flows and the market price of our securities, may be materially and adversely affected by developments in these export markets relating to inflation, interest rates, currency fluctuations, protectionism, government subsidies, price and wage controls, exchange control regulations, taxation, expropriation, social instability or other political, economic or diplomatic developments. For example, certain target countries to which we export may impose buying restrictions in our industry, which may adversely affect our sales. We have no control over these conditions and developments which could adversely affect us and our business, financial condition, results of operations and cash flows or the price or market of our securities.

Developments in other emerging and developed markets may adversely affect the market price of our securities and our ability to raise additional financing.

Our financial condition and the market price of our securities may be adversely affected by declines in the international financial markets and world economic conditions. Chilean securities markets are, to varying degrees, influenced by general economic, political, social and market conditions in other emerging and developed market countries, especially those in the United States, Europe, China and Latin America. Although economic conditions are different in each country, investors’ reactions to developments in one country can affect the securities markets and the securities of issuers in other countries, including Chile. Negative developments in the international financial markets in the future could adversely affect the market price of our securities and impair our ability to raise additional capital.

Since late 2009, high levels of sovereign debt and insufficient public sector revenues have resulted in a European sovereign debt crisis. As of the date of this annual report, credit rating agencies have downgraded the credit ratings of many of the Eurozone governments, including Greece, Spain, Italy, Portugal and France, among

20

others. During 2012 and the first quarter of 2013, the deepening of this crisis has caused a general economic downturn in Europe, which has negatively affected the banking and credit systems, employment and production. As a result, we may face difficulties in obtaining loans or we may incur higher debt servicing costs in connection with loans obtained from European financial institutions.

Risks Relating to Our Securities

The non-payment of funds by our subsidiaries could have a material and adverse effect on our business, financial condition, results of operations and ability to service our debt, including our securities

Our cash flow and our ability to service debt is dependent, in part, on the cash flow and earnings of our subsidiaries and the payment of funds by those subsidiaries to us, in the form of loans, interest, dividends or otherwise. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due under the terms of our securities or to make any funds available for such purpose. Furthermore, claims of creditors of our subsidiaries, including trade creditors, will have priority over our creditors, including holders of our securities, with respect to the assets and cash flow of the subsidiaries. Our right to receive assets of any of our subsidiaries upon their liquidation or reorganization (and the consequent right of the holders of our securities to participate in those assets) will be effectively subordinated to the claims of that subsidiary’s creditors.

Changes in Chilean tax laws could lead us to redeem our securities

Under current Chilean law and regulations, payments of interest made from Chile to holders of debt securities who are neither residents nor domiciled or organized in Chile for purposes of Chilean taxation will, generally, be subject to Chilean withholding tax at a rate of 4.0%. Subject to certain exceptions, we will pay additional amounts (as described in “Item 10. Additional Information—Taxation”) so that the net amounts received by the holder of the notes (including additional amounts) after such Chilean withholding tax will equal the amounts that would have been received in respect of the notes in the absence of such Chilean withholding tax. In the event of certain changes in Chilean tax laws requiring that we pay additional amounts that are in excess of the additional amounts that we would owe if payments of interest on our securities were subject only to a 4.0% withholding tax, we will have the right to redeem our securities.

Credit rating downgrades below investment grade could have a material and adverse effect on our business, financial condition, results of operations and ability to service our debt, including our securities

Credit rating agencies could downgrade our ratings either due to factors specific to us, a prolonged cyclical downturn in the forestry industry or macroeconomic trends (such as global or regional recessions) and trends in credit and capital markets more generally. Any decline in our credit rating would increase our cost of borrowing and may significantly harm our financial condition, results of operations and profitability, including our ability to refinance our existing indebtedness.

In October 2012, citing soft pulp prices and our increased leverage due to the Flakeboard acquisition and the construction of our Montes del Plata pulp plant in Uruguay, Fitch Ratings (“Fitch”) downgraded our foreign and local currency Issuer Default Ratings (IDF) to “BBB” from “BBB+”, in addition to downgrading our national scale rating from “AA (cl)” to “AA- (cl)”. Fitch also downgraded the foreign currency IDR of Alto Paraná S.A., one of our Argentine subsidiaries, to “BBB” from “BBB+”. The unsecured debt issued by Alto Paraná and us was also downgraded to “BBB” and “AA- (cl)”, respectively, from “BBB+” and “AA”. On February 6, 2013, Feller Rate, a Chilean subsidiary of S&P, lowered our national scale rating to AA- from AA, citing the adoption of an aggressive financial policy combined with a cycle of low prices and increased costs of raw materials. On March 7, 2013, Moody’s Investors Service (“Moody’s”) downgraded our senior unsecured ratings to Baa3 from Baa2 with a negative outlook, citing deterioration in our performance coupled with significant increase in debt that resulted in significant increase in leverage. Additionally, Moody’s downgraded the rated notes of Alto Paraná S.A. to Baa3 from Baa2. On March 27, 2013, Standard & Poor’s Ratings Services (“S&P”) lowered its rating on us from “BBB” to “BBB-”, citing high debt, our recent acquisitions, and soft pulp prices and rising operating costs. It considered our financial risk profile to be “intermediate” due to expectations of improved leverage. We cannot assure you that we will not be subject to further credit rating downgrades. Credit rating downgrades below investment grade could have a material and adverse effect on our business, financial condition, results of operations and ability to service our debt, including our securities.

Item 4. Information on the Company

DESCRIPTION OF BUSINESS

We believe that, as of December 31, 2012, we were one of Latin America’s largest forest plantation owner, and that we are Chile’s largest exporter of forestry and wood products in terms of sales revenue. We have industrial operations in Chile, Argentina, Brazil, the United States and Canada. As of December 31, 2012, we had approximately 1.0 million hectares of plantations in Chile, Argentina, Brazil and Uruguay. During 2012, we harvested 49,939 million cubic meters of sawlogs and pulplogs and sold 8.7 million cubic meters of wood products, including sawn timber (green and kiln-dried lumber), remanufactured wood products and panels (plywood, medium density fiber board, or MDF, particle board, or PBO, and high density fiber board, or HB). During 2012, we sold 2,928.8 thousand tonnes of pulp in the form of hardwood beached pulp, softwood bleached pulp, softwood unbleached pulp and fluff.

Based on information published by Resource Information Systems, Inc., an independent research company for the pulp and paper industry, as of December 31, 2012, we were one of the world’s largest producers of bleached and unbleached softwood kraft market pulp in terms of production capacity, with an estimated 7.6% share of the total world production capacity of bleached softwood kraft market pulp and a 19.1% share of the total world production capacity of softwood kraft market unbleached pulp. “Market pulp” is pulp sold to manufacturers of paper products, as opposed to pulp produced by an integrated paper producer for use in its paper production facilities. “Kraft pulp” is pulp produced using a chemical process.

Based on information published by Resource Information Systems, Inc., we were also one of the world’s lowest-cost producers of softwood kraft market pulp. We believe that we are able to produce our products at a lower cost than our competitors because of the high growth rate and short harvest cycle of radiata and taeda pine compared to other commercial softwoods, the advanced genetic and silviculture techniques we apply in our forest management, our modern mill facilities and, in the case of Chile, the proximity of our operations to Pacific coast ports.

History

Celulosa Arauco y Constitución S.A. is a corporation (sociedad anónima) organized under the laws of Chile and subject to certain rules applicable to Chilean public corporations (sociedades anónimas abiertas). Our principal executive offices are located at Avenida El Golf 150, 14^th Floor, Las Condes, Santiago, Chile, and our telephone number is +56-2-2461-7200.

We were formed on September 14, 1979 in a merger between Industrias de Celulosa Arauco S.A., or Industrias Arauco, and Celulosa Constitución S.A., or Celulosa Constitución. Our two predecessor companies were created in the late 1960s and early 1970s by Corporación de Fomento de la Producción, or Corfo, a Chilean government development corporation, to develop forest resources, improve soil quality in former farming areas and promote employment. As part of the Chilean government’s privatization program, Corfo sold Industrias Arauco to Compañía de Petróleos de Chile S.A., or Copec, in 1977 and Celulosa Constitución to Copec in 1979. In October 2003, Copec transferred all of its gasoline- and fuel-related business assets to a new subsidiary, and changed its legal name to Empresas Copec S.A., or Empresas Copec. See “Item 7. Major Shareholders and Related Party Transactions—Major Shareholders.”

In 1996, we acquired Alto Paraná S.A., an Argentine company, which, at that time, owned plantations and other land in Argentina and manufactured and sold bleached softwood kraft pulp. With this acquisition, we expanded our market opportunities outside of Chile.

In 2000, we acquired 98% of the shares of Forestal Cholguán S.A., or Cholguán, and 50% of Trupán S.A., or Trupán, which permitted us to enter the MDF and HB markets, and in 2002, we began operations at two new MDF mills, one in Chile and one in Argentina.

22

In 2005, we expanded our presence in Chile, Argentina and Brazil through a series of acquisitions that increased our land holdings and the production capacity of various sectors of our business.

On June 30, 2006, through our subsidiaries Aserraderos Arauco S.A., Forestal Celco S.A., Bosques Arauco S.A. and Forestal Valdivia S.A., we acquired the forestry assets of Cementos Bío-Bío S.A. The acquisition represented an investment of U.S.$133.3 million. The acquired assets consisted of 21,000 hectares of pine plantations, one sawmill with an annual production capacity of approximately 250,000 cubic meters per year and a remanufacturing facility.

On September 27, 2007 we entered into an agreement for the joint ownership of land in Brazil with Stora Enso Oyj, a Finnish-Swedish multinational corporation. Pursuant to the agreement, we acquired 80% of the shares in Stora Enso Arapoti Empreendimentos Agrícolas S.A., now Arauco Florestal Arapoti S.A., which owns 50,000 hectares of land, including 25,000 hectares of pine and 5,000 hectares of eucalyptus plantations; 20% of the shares in Stora Enso Arapoti Indústria de Papel S.A., which owns a paper mill with an annual production capacity of 205,000 tons of light weight coated paper; and 100% of the shares of Stora Enso Arapoti Serraria Ltda., which owns a sawmill with an annual production capacity of 150,000 cubic meters per year. This alliance required an investment of U.S.$208.4 million, which was financed with our resources and commercial bank loans.

On May 17, 2009, our subsidiary Inversiones Arauco Internacional Limitada (previously known as Arauco Internacional S.A.), or “Arauco Internacional”, and a subsidiary of Stora Enso Oyj agreed through a joint venture partnership to acquire the Uruguayan subsidiaries of ENCE, which acquisition was completed on October 16, 2009. The companies acquired by the joint venture partnership were Eufores S.A., Celulosa y Energía Punta Pereira S.A. and Zona Franca Punta Pereira S.A. The main assets of these subsidiaries included 130,000 hectares of land, of which 73,000 have forestry plantations, 6,000 hectares under agreements with third parties, an industrial site, the necessary environmental permits for the construction of a pulp mill, a river terminal, a chip producing mill and a nursery. The agreed value of these assets, pursuant to the aforementioned transaction, was U.S.$335 million, of which Arauco paid 50% (or U.S.$167.5 million). See “Item 5. Operating and Financial Review and Prospects—Results of Operations”.

On August 26, 2009, our subsidiary Placas do Paraná S.A. acquired 100% of the shares of Tafisa Brasil, by means of a share purchase agreement executed among SCS Beheer, B.V., Tafiber – Tableros de Fibras Ibéricos, S.L. (each of which is a subsidiary of Sonae Indústria, SGPS, S.A.) and Placas do Paraná S.A. Pursuant to the transaction, we paid a purchase price of U.S.$227 million, of which U.S.$165.2 million was allocated to pay the value of the shares of Tafisa Brasil, with the balance corresponding to liabilities that the acquired company maintained. The primary asset of Tafisa Brasil (which has been renamed “Arauco do Brasil S.A.”) is a panel production facility located in the city of Pien, Brazil, which is in the state of Paraná. The facility has an annual total installed capacity of 640,000 cubic meters, which includes three production lines: two lines producing MDF and one line producing particleboard. The facility also has added-value lines to produce products for the construction and furniture industries.

On September 27, 2009, Arauco and its subsidiary Arauco Internacional, executed a series of joint venture agreements with Stora Enso, pursuant to which Stora Enso Amsterdam B.V. agreed to transfer ownership of 100% of the shares of Stora Enso Uruguay S.A. to Forestal Cono Sur. As a consequence of this transaction, Arauco and Stora Enso equally control all assets that both companies own in Uruguay, which includes 74,000 hectares owned by Stora Enso (including 17,300 hectares which are already planted with forests) and 39,000 hectares owned by Arauco (of which 27,400 are already planted with forests). These assets, and those that we acquired from ENCE in October of 2009, have helped to secure a strategic basis to consider the construction of the Montes del Plata pulp mill in Uruguay.

In April 2010, our subsidiary Arauco do Brasil S.A. acquired 50% of the shares of Dynea Brasil S.A. from Dynea AS for U.S.$15 million. As a result of this acquisition, we now own 100% of the shares of Dynea Brasil S.A. Dynea Brasil S.A. was absorbed by Arauco do Brasil S.A. in May 2010.

On January 18, 2011 Arauco and Stora Enso agreed to carry out the construction of a state of the art pulp mill with an annual guaranteed capacity of 1.3 million tons, a port and a power producing unit based on renewable sources, all located in Punta Pereira, department of Colonia, Uruguay. The total estimated investment is

On November 17, 2011, Centaurus Holdings S.A., a Brazilian company that is 51% owned by Klabin S.A. and 49% by our subsidiary Arauco Forest Brasil S.A., acquired the shares of Florestal Vale do Corisco Ltda., which has 107,000 hectares of land in the Brazilian state of Paraná. The total purchase price for the proposed transaction was U.S.$473.5 million, of which we paid 49%. We received antitrust approval for this project from Brazilian authorities on July 18, 2012.

On December 20, 2011, Alto Paraná acquired 100% of the shares of Greenagro S.A. (“Greenagro”), a company duly incorporated under the laws of Argentina, for a total purchase price of U.S.$10.7 million. Greenagro is engaged in forestry activities in the area of Isla Victoria, province of Entre Ríos, Argentina. As of the date of this annual report, the closing of the acquisition remains subject to antitrust review in Argentina by the National Commission for the Defense of Competition (Comisión Nacional de Defensa de la Competencia).

On December 29, 2011, Arauco Panels USA, one of our U.S. subsidiaries, entered into an asset purchase agreement to acquire an industrial facility in Moncure, North Carolina for U.S.$56 million plus approximately U.S.$6 million in respect of working capital, subject to adjustment based on actual working capital at closing. The facility includes medium-density fiberboard (MDF) and high-density fiberboard (HDF) production lines with annual production capacity of up to 330,000 cubic meters, a particleboard production line with annual production capacity of up to 270,000 cubic meters and two melamine product production lines. This transaction was closed in January 2012.

On June 7, 2012, we signed a share purchase agreement to acquire 100% of the shares of Flakeboard Company Limited (“Flakeboard”), a Canadian company, for a total purchase price of U.S.$242.5 million. Flakeboard is a key North American producer of wood paneling for furniture. It owns and operates seven panel mills in Canada and the U.S. with an aggregate annual production capacity of 1.2 million cubic meters of MDF panels, an annual production capacity of 1.2 million cubic meters of PB, and an annual production capacity of 634,000 cubic meters of melamine. This transaction closed in September 2012.

Forestry Activity

Radiata pine grows at the fastest rates within a narrow band of latitude and under certain climatic conditions. One of Chile’s main advantages in the forestry products industry lies in the short growing cycle of its radiata pine plantations. The faster growth rate of radiata pine trees in Chile allows harvesting of pulplogs and sawlogs 16 to 18 years after planting and of high quality sawlogs 25 years after planting. For most temperate softwood forests in the Northern Hemisphere this range is 18 to 45 years for pulplogs and 50 to 150 years for high quality sawn timber. Consequently, the Chilean forestry industry is a relatively low cost producer, since a Chilean producer generally requires less time and a smaller area to produce the same volume of pine as its North American or European competitors, who face lower forest growth rates and higher transportation and investment costs as a result of the larger tracts of forests necessary to produce equivalent yields of softwood. Accordingly, since the mid-1970s, we have focused our forest management toward the application of advanced genetic and silviculture techniques to increase productivity and the quality of our plantations.

Eucalyptus, which we began planting in 1989, grows well in the forest regions of Chile. Once planted, eucalyptus trees require no further forest management (other than fire control and reduction of weeds) until harvest. The average harvest cycle of eucalyptus plantations is approximately 12 years. Once harvested, Eucalyptus can be replanted or regrown.

26

Throughout our history, we have demonstrated a continued commitment to the improvement of our forest management policies. In particular, we have adopted environmentally sensitive policies towards our holdings of native forests, which are protected and preserved in their entirety. Our products come from our established plantations only; we do not sell any products derived from our native forests. We conduct our forestry operations in accordance with current legislative and environmental sustainability standards. Certain of our subsidiaries have received various environmental certifications as of the date of this annual report, which include, but are not limited to the following:

• Sustainable Forest Management Certification: the Chilean certification of sustainable forest management, as determined since 2004 by the PEFC (Program for the Endorsement of Forest Certifications Schemes). PEFC is an international non-profit, non-governmental organization dedicated to promoting sustainable forest management;

• Forest Stewardship Council (FSC) Certification: a forest management certification aimed at promoting forest management that is environmentally responsible, socially beneficial and economically viable for the world’s forests. FSC is a non-profit organization devoted to encouraging the responsible management of the world’s forests;

• Chain of Custody Certification: a certification granted by the PEFC and designed to ensure that certified raw materials are used in finished product;

• Chain of Custody and Controlled Wood Certification: a certification from the FSC that is designed to ensure traceability of certified and uncertified wood from the forest to the finished product;

• Environmental Management System ISO 14001: a certification issued by the International Standards Organization (ISO), awarded to organizations that comply with environmental legislation, monitor significant environmental impacts, prevent pollution and maintain a continuing program of environmental improvement. ISO is an international non-profit, non-governmental organization dedicated to developing international business standards;

• Occupational Health and Safety Assessment Series (OHSAS) 18001: a certification awarded for the effective management of conditions and factors that may adversely affect the work environment of employees, temporary workers, contractors and other persons who are in the workplace.

Forest Plantations

As of December 31, 2012, our planted forests consisted of 75.8% radiata, taeda and elliottii pine and 22.4% of mainly eucalyptus. Radiata and taeda pine have a rapid growth rate and a short harvest cycle compared to other commercial softwoods. Radiata and taeda pine are sufficiently versatile for both the production of forestry and wood products and the production of long fiber pulp for sale to manufacturers of paper and packaging.

We seek to manage our forestry resources in a way that ensures that the annual growth of our forest is equal to or greater than the volume of resources harvested each year. In 2012, Arauco planted a total of 77,021 hectares and harvested a total of 49,939 hectares in Chile, Argentina, Brazil and Uruguay (these amounts include, with respect to Brazil, 100% of the plantations owned by companies controlled by Arauco, and with respect to Uruguay, 50% of the plantations owned in Uruguay by us through the Montes del Plata joint venture). We believe that our annual harvests and plantations long-term sustainable equilibrium are approximately 67.2 thousand hectares (including 100% of the plantations owned by the Montes del Plata joint venture, and, with respect to plantations owned by Brazil, 100% of Forestal Arapotí, 100% of Arauco Forest Brasil and 100% of Mahal-owned plantations).

Our planted radiata pine forests are located in central and southern Chile, and most are located in close proximity to our major production facilities and to port facilities. As of December 31, 2012, our aggregate radiata pine holdings comprised 41% of all Chilean radiata pine plantations, making us the country’s largest radiata pine plantation owner according to the Chilean Forestry Institute. As of December 31, 2012, we owned approximately 1.1 million hectares of land in Chile, of which 736.6 thousand hectares are forest plantations.

27

As of December 31, 2012, we owned approximately 263,400 hectares of forest and other land in Argentina, approximately 145,100 hectares of forest and other land in Brazil and approximately 135,000 hectares of forest and other land that the Montes del Plata joint venture owns in Uruguay. Of the total land we own in these three countries, approximately 171,100 hectares of land is planted with taeda pine and elliotti pine, a species of softwood that has a growth rate similar to that of radiata pine. The balance includes plantations of other species of trees, land to be planted, protected areas and natural forests.

The following table sets forth the number of hectares and types of uses of our land holdings and rights, as of December 31, 2012.

Also includes 54,945 hectares for which we have the right to harvest but do not own, of which 42,763 hectares are in Chile, 11,877 hectares are in Uruguay and 305 hectares are in Argentina.

Land Acquisition and Afforestation

Our total land assets have increased from fewer than 170,000 hectares in 1980 to 1,658,751 hectares as of December 31, 2012. That number does not include 15,752 hectares of land owned by Forestal Río Grande S.A., of which 2,564 hectares consists of plantations. In the five years ending December 31, 2012, we purchased 208,787 hectares of land, of which 45,076 hectares were purchased in Chile, 5,553 in Argentina, 74,778 in Brazil and 83,381 in Uruguay. For more information regarding our material land acquisitions, see “—History” herein.

We expect to acquire additional land if we are presented with the possibility to do so at a desired price or location. There can be no assurance that we would be able to acquire land at the desired price or location.

We plan to continue our policy of supplementing our pulplog production with purchases from domestic third parties. We believe that this policy is economically efficient, given the significant quantities of pulplog available from third parties and our increasing proportion of sawlogs yielded from our plantations. We believe that the aggregate of our existing plantations, land currently held by us that we intend to afforest and the third-party purchases we make in the ordinary course of our business will be sufficient to satisfy our anticipated future demand for sawlogs and pulplogs.

28

Forest Management

For our pine plantations, our forestry management activities seek to increase sawlogs through advanced genetic techniques, planting and site preparation procedures, thinning and pruning. Managed forests can produce trees of larger diameter and, if pruned, a higher proportion of clear wood, which generally commands a higher price than knotted wood. Although some land is not suitable for the production of pruned logs, as of December 31, 2012, over 64% of our pine forests in Chile were designed for clear wood production.

For our eucalyptus plantations, our forestry management activities seek to increase the amount of fiber production per hectare through advanced genetic techniques and planting and site preparation procedures. Eucalyptus is more expensive to plant than pine; however, after planting, eucalyptus requires minimal forest management, yields more fiber per hectare and has a shorter growth cycle and greater wood density than pine, resulting in a greater amount of pulp production per hectare.

As of December 31, 2012, we had 16 nurseries in Chile, Argentina, Brazil and Uruguay, in which we grow seedlings using seeds and using cuttings from genetically selected trees. To achieve higher quality trees and an increased growth rate, we apply strict selection criteria to the trees from which seedlings are produced. We then plant the seedlings manually. Depending upon the species of tree to be planted and the nutrient and physical characteristics of the soil, we may also undertake a certain amount of ground preparation before planting. Our other principal forest activities are thinning, pruning and harvesting.

Thinning, or culling inferior trees from the plantation, occurs in the following two stages:

• Thinning to waste. Thinning to waste occurs after four to six years and results in an average reduction of the number of trees per hectare from 1,250 to approximately 700. Thinning to waste is conducted once or twice per year on up to 500 hectares of our plantations.

• Commercial thinning. Thinned trees are used in pulp production or, depending on the quality of the particular land, as sawlogs. Commercial thinning occurs at eight to 12 years and results in an average reduction of the number of trees per hectare from 700 to approximately 450. Commercial thinning is conducted once or twice per year.

This high level of thinning benefits Arauco for the following reasons:

• the cost of planting is relatively low,

• the higher number of young trees provide each other with natural protection from the elements, and

• the high degree of selection that thinning makes possible leaves only the highest quality trees to be harvested.

Pruning involves removing branches, the source of knots, which are the main defect in sawn timber. Pruning results in a high-quality clearwood sawlog of 5.3 meters from each tree, and is conducted three times:

• when trees are five to nine years old,

• one year later, when trees are six to ten years old, and

• one year later, when trees are seven to eleven years old.

Our eucalyptus plantations are neither thinned nor pruned.

Harvesting timber involves felling trees, removing branches from the logs, cutting the logs into appropriate sections and loading the logs onto trucks for transport to sawmills, panel mills or pulp mills. We use the lower section of the radiata pine, comprising the first 7 to 12 meters, in sawmills and plywood mills. We use the mid-

29

section of the radiata pine, comprising, on average, the next 8 to 13 meters, in either sawmills or pulp mills, depending on the diameter and quality of the pine. We use the top section of the tree for pulp, MDF and medium-density particleboard (MDP) production.

We monitor product demand and our current inventory levels, and we match harvests from sections of our plantations that will provide the optimal yield given our product requirements. This process involves the use of sophisticated operations research models and close communication between our different operating areas to ensure that the correct amounts of timber of the required characteristics are supplied. We replant as soon as practicable after harvesting, with an average period between harvesting and replanting of one year.

The following table illustrates, on a hectare basis, the extent of our thinning, pruning and harvesting activities in Chile during the periods indicated.

	Year ended December 31,
	2010		2011		2012
			(in hectares)
Thinning		11,570		12,992		12,097
Pruning		27,335		23,330		19,298
Harvesting		30,158		33,955		36,781

We manage our forest activities, but we hire independent contractors to perform the bulk of our operations, including planting, maintenance, thinning, pruning, harvesting, transportation and access road construction. As of December 31, 2012, we had arrangements with more than 308 independent contractors that employed over 13,870 workers in Chile. Many of these contractors have long-standing relationships with us, but we award many contracts based on competitive bids. We believe that our arrangements with independent contractors provide greater flexibility and efficiency than performing these activities directly.

Our plantations are interspersed with native forest and farmland, and, as a result, they are naturally protected against the spread of certain diseases. In addition, our subsidiary Investigaciones Forestales Bioforest S.A., or “Bioforest”, has developed strategies to protect our forests from pests and diseases. During the last five years, radiata pine plantations have been affected by two health problems in particular: 1) the sirex noctilio, a wasp which attacks stressed trees, has caused a natural selection for thinning and 2) the disease produced by phytophthora pinifolia has reduced the growth rate of certain trees. To mitigate the effects of the sirex noctilio, Bioforest has implemented a biological control program under which it has released into the affected forests natural enemies of the sirex noctilio, including the nematode, the beddingia siricidicola and the parasitoid ibalia leucospoide. To control the spread of phytophthora pinifolia, Bioforest has begun a genetic program to make our trees more tolerant to this disease and has also begun dispersing in our forests a fertilizer that further promotes resistance. For more information regarding certain risks to our forests presented by disease, see “Item 3. Key Information—Risk Factors—Disease or fire could affect our forests and manufacturing processes and, in turn, adversely affect our business, financial condition, results of operation and cash flows.”

We operate an extensive fire control organization that interacts with the fire control organizations of other forestry companies to ensure that any fire damage to our forests is minimal. The operation consists primarily of a system of spotter towers, manned 24 hours a day during the summer months, from which spotters report the direction of any fire observed to a central command post, where the fire’s exact location is determined and an appropriate ground and/or aerial response is formulated. The focus of this operation is to detect and control fires in less than 10 minutes in order to prevent fires from spreading. Over the last five years, this system has limited fire damage to our forests to an average of 0.3% of the plantations per year. Nevertheless, in January 2012, a fire affecting the Eighth Region of Chile destroyed approximately 8,200 hectares of our forest plantations and our Nueva Aldea plywood mill. See “Item 3. Key Information—Risk factors–Risks Relating to Us and the Forestry Industry— Disease or fire could affect our forests and manufacturing processes and, in turn, adversely affect our business, financial conditions, results of operations and cash flows.”

Forest Production

We harvested 18.9 million cubic meters of logs during the year ended December 31, 2012, consisting of 9.4 million cubic meters of sawlogs, 6.6 million cubic meters of pine pulplogs and 2.9 million cubic meters of eucalyptus pulplogs and other logs. We did not export any pulplogs during 2012 because substantially all of the pulplogs from our forests were used in our pulp or panel mills. During 2012, our sawmills and panel mills used 6.0 million cubic meters of sawlogs, and no sawlogs were exported. We also sold 2.3 million cubic meters of sawlogs to unaffiliated domestic sawmills during 2012.

A log merchandising facility located at the same site as our Horcones I and Horcones II sawmills optimizes, cuts and classifies wood destined for our plywood facility, sawmills or pulp mills with an annual processing capacity of 1.7 million cubic meters of logs per year. The Nueva Aldea Complex also includes a log merchandising facility, with an annual processing capacity of 2.6 million cubic meters of logs per year.

Pulp

We believe that we were Chile’s largest producer of bleached and unbleached softwood market pulp in terms of production in 2012. For the year ended December 31, 2012, pulp sales were U.S.$1,856.5 million, representing 43.4% of our total sales revenue for the period.

Pulp obtained from wood fibers is mainly used in the manufacture of printing and writing paper, hygienic and sanitary paper, board and packaging. Whether a specific kind of pulp is suitable for a particular end use depends not only on the type of wood but also on the process used to transform the wood into pulp. Pulp made from softwoods, such as radiata pine, has long fibers and is used to provide strength to paper products. Hardwood bleached pulp is used primarily for printing and writing papers and for tissue. Unbleached pulp is used primarily for linerboard (a packaging material). Pulp made from hardwoods, such as eucalyptus, has short fibers and is used in combination with long fiber in manufacturing paper products.

We use a chemical process, known as the kraft process, in our pulp mills in Chile and Argentina. The raw wood is in the form of pulplogs and chips, which are used in the production process to produce pulp. The pulplogs are first debarked and chipped. The chips are then screened, mixed and cooked with chemicals to separate the bulk of the lignin from the wood fibers. After the material is screened and washed, it is then passed to high-density tanks. For bleached pulp, the next step is a five-stage bleaching process using chemicals, primarily chlorine dioxide. At all of our pulp mills, the bleaching process is preceded by an oxygen delignification stage. Then, the fibers are subjected to a final stage where a sheet is formed and subsequently dried and baled for transport to customers. The lignin and bark produced during this process is used as fuel in the boilers to produce steam, providing heat and generating electricity for the mill. Our bleached pulp is bleached to a 90+ brightness level, as measured by the ISO test procedure, which is one of the industry’s measurement methods.

Pulp Mills

As of December 31, 2012, we owned and operated five pulp mills in Chile and one in Argentina, with an aggregate installed annual production capacity of approximately 3.2 million tonnes. Our six pulp mills produced 2.5 million tonnes of bleached pulp and 0.4 million tonnes of unbleached pulp in 2012.

All of our pulp mills in Chile, except for the Nueva Aldea Mill and the Licancel Mill, are certified under ISO 9001:2000 and ISO14001:2004. The Nueva Aldea Mill and the Licancel Mill were certified under ISO 9001:2008 and ISO 14001:2004 in February 2010. The Alto Paraná Mill in Argentina is certified under ISO 9001:2000 and ISO14001:2004. No seasonal factors affect plant utilization, and the pulp mills generally run at full capacity throughout the year, with eight to ten days of maintenance normally scheduled every 12 months.

⁽¹⁾ Operations at the Licancel Mill were temporarily suspended for approximately six months from June 2007 until January 2008.

⁽²⁾ During 2009, the Licancel Mill produced unbleached pulp for a three-month period. During 2010, the Licancel Mill produced unbleached pulp for a nine–month period. During 2011, the Licancel Mill produced unbleached pulp for a seven–month period.

The following is a description of each of our pulp mills in Chile and Argentina.

Chile

Arauco I. Arauco I, which started-up in 1972, is located at the Arauco Mill in the heart of a group of our radiata pine plantations in the Eighth Region of Chile. Arauco I produces elementary chlorine-free pulp, which does not use chlorine gas. Elementary chlorine-free pulp is also produced by most of our competitors in each of the world’s major pulp producing regions. The installed annual production capacity of Arauco I is approximately 290,000 tonnes of eucalyptus and pine bleached kraft pulp.

Arauco II. Also located at the Arauco Mill, Arauco II was completed in 1991. Arauco II’s pulping process is generally the same as that of Arauco I, but it includes technological improvements in its production process and environmental design. Arauco II is also equipped to produce elementary chlorine-free pulp. The installed annual production capacity of Arauco II is approximately 500,000 tonnes of pine bleached kraft pulp.

As a consequence of the earthquake that occurred in Chile on February 27, 2010, the operations of Arauco II were temporarily suspended until February 2, 2011, when it resumed its operations.

Constitución Mill. The Constitución Mill is located in the heart of a group of our radiata pine forests in the Seventh Region of Chile. As of December 31, 2012, the Constitución Mill was the largest unbleached softwood market pulp mill in the world, with an installed annual production capacity of approximately 355,000 tonnes. In February 2006, the COREMA of the Seventh Region of Chile approved an environmental impact study for the construction of a new pipeline for the Constitución Mill, which commenced operations in February 2007. The unbleached pulp produced in this mill does not use any chlorine in its production process.

32

Licancel Mill. We acquired the Licancel Mill in September 1999. It is located in Licantén, which is 250 kilometers south of Santiago. The mill has an installed annual production capacity of approximately 145,000 tonnes of eucalyptus kraft pulp and pine bleached and unbleached kraft pulp. The Licancel Mill is equipped to produce elementary chlorine-free pulp.

In June 2007, our operations at the Licancel Mill became subject to an environmental review by Chilean environmental regulators and the public in connection with the death of fish in the Mataquito River, approximately 15 kilometers downstream of the mill. As a result, Chilean authorities, including the health authorities and the Superintendencia de Servicios Sanitarios (Sanitary Services Superintendency), required that we suspend activities at the Licancel Mill and that we suspend any further discharge into the river. We estimate that the suspension of operations at the Licancel Mill resulted in a total loss of profits of U.S.$24 million. Any future suspension of operations at the Licancel Mill may adversely affect our business, financial condition, results of operations and cash flows. See “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry—Environmental concerns led to the temporary suspension of our operations at the Valdivia Mill in 2005 and at the Licancel Mill in 2007, which adversely affected, and in the future may continue to adversely affect, our business, financial condition, results of operations and cash flows and “Item 8. Financial Information- Legal Proceedings.”

Valdivia Mill. The Valdivia Mill commenced operations in February 2004. The Valdivia Mill is located in Fourteenth Region of Chile (which was previously part of the Tenth Region of Chile), an area with significant radiata pine and eucalyptus plantations. The Valdivia Mill has an installed potential annual production capacity of approximately 550,000 tonnes of bleached pulp, consisting of softwood pulp and eucalyptus pulp. The Valdivia Mill is equipped to produce elementary chlorine-free pulp.

The Valdivia Mill has been subject to legal and administrative proceedings by the Chilean environmental regulators. Primarily, it has been alleged that the Valdivia Mill’s operations impacted the nearby Carlos Anwandter Nature Sanctuary and contributed to the migration and death of black-neck swans in an area downstream from the mill on the Cruces River. For a discussion of the administrative and litigation proceedings in which we have been involved as a result of our operations at the Valdivia Mill, see “Item 8. Financial Information—Legal Proceedings.”

Nueva Aldea Mill. Located in the Eighth Region of Chile, this mill was completed in 2006 and currently has a production capacity of 1,027,000 tonnes per year, half of which is for the production of pine bleached kraft pulp and the other half of which is for the production of eucalyptus bleached kraft pulp. The Nueva Aldea Mill is equipped to produce elementary chlorine-free pulp.

On February 20, 2006, the COREMA of the Eighth Region of Chile approved the environmental impact study for the construction and operation of the Nueva Aldea Mill Pipeline, which permits the mill to discharge certain liquid effluents into the ocean. The Nueva Aldea Mill pipeline’s startup and commissioning period (of 6 months) commenced in the first quarter of 2010. However, as result of damages to the pipeline caused by the earthquake that occurred in Chile on February 27, 2010, we needed to temporarily suspend our use of the pipeline and discharge the effluents of the Nueva Aldea Mill in the same place in which the mill’s wastewater was discharged prior to the opening of the pipeline. On July 31, 2010, our repairs to the damaged pipeline were completed and the startup and commissioning period was restarted. Since January 31, 2011, the pipeline has been fully operational.

On February 9, 2009, COREMA approved our request to increase the Nueva Aldea Mill’s production to 20% above the previously authorized level, which was 856,000 tonnes per year. The COREMA determined that it was not necessary for us to present an environmental impact study in connection with our request for increased production. On October 7, 2009 we presented an environmental impact declaration requesting an additional increase in the production capacity of the Nueva Aldea Mill from 1,027,000 tonnes to 1,200,000 tonnes per year. The COREMA approved this request on February 4, 2010. As of the date of this annual report, plans to carry out this increase in production capacity are underway.

Argentina

Alto Paraná Mill. Alto Paraná’s softwood pulp mill is located in the Province of Misiones, a region whose soil and climate are favorable for the rapid growth of pine trees. The Alto Paraná Mill is the only bleached softwood

33

kraft market pulp facility in Argentina. The mill has an installed annual production capacity of 350,000 tonnes of pulp, of which 50% is bleached softwood pulp for paper use, currently representing almost all of the total bleached softwood pulp production capacity in Argentina, and 50% is fluff pulp.

Uruguay

Montes del Plata Joint Venture. In January 2011, we and Stora Enso agreed to commence construction of a new pulp mill with an annual capacity of approximately 1.3 million tonnes, a port and a power generation facility based on renewable resources, all located in Punta Pereira, department of Colonia, Uruguay. The total estimated investment is U.S.$2,000.0 million. After securing the necessary permits, we broke ground in May 2011 to begin construction. In September 2011, two of our Uruguayan joint venture companies entered into two credit facilities to finance the construction of the proposed project. For more information regarding these credit facilities, see “Item 3. Key Information—Risk Factors—Risks Relating to Uruguay—Economic conditions in Uruguay may have a direct impact on our financial condition and results of operations.”

As of December 2012, we were approximately 78.4% complete with construction. We currently anticipate initiating operations in the third quarter of 2013.

Production Costs

Based on information published by Resource Information Systems, Inc., our cash costs for softwood pulp production are lower than the average costs of market pulp producers in Canada, the United States and Scandinavia, particularly with respect to timber and energy costs. While our modern facilities result in depreciation exceeding some of such Northern Hemisphere producers, our costs are still lower than the average costs of our Northern Hemisphere competitors, on a total delivered cost basis. The following table compares our costs for the production of bleached softwood kraft market pulp to the average cost of market pulp producers in selected regions in the Northern Hemisphere for the year ended December 31, 2012.

Sales

The total production of bleached kraft market pulp in the global market during the year ended December 31, 2012 was 55.7 million tonnes. Based on information published by Resource Information Systems, Inc., we believe that our production represented 5.5% of this market in 2012. During the year ended December 31, 2012, we sold 94.4 % of our bleached pulp in our export markets, principally to customers in Asia and Western Europe.

34

Integrated manufacturers dominate the world production of unbleached softwood pulp, which leaves non-integrated companies that sell market pulp, like us, with only a small percentage of total production. “Market pulp” is pulp sold to manufacturers of paper products, as opposed to pulp produced by an integrated paper producer for use in its paper production facilities. With a total world production of unbleached softwood kraft pulp of 2.5 million tonnes for 2012, according to Resource Information Systems, Inc., our Company was the world’s largest single producer of unbleached softwood market pulp, with 14.2% of the total market in 2012. During the year ended December 31, 2012, 87.3% of our total unbleached market pulp sales consisted of export sales. While for the last five years Asia has been our principal export market for unbleached market pulp, we continually seek niche markets for our products in Western Europe and the United States.

The following table sets forth, by region, the sales volumes of bleached and unbleached pulp for the years indicated.

While there are many grades and varieties, pulp is a commodity that is marketed primarily on the basis of price and service. In marketing our pulp, we seek to establish long-term relationships with non-integrated end users of pulp by providing a competitively priced, high-quality, consistent product and excellent service. The quality of our pulp derives from the high standards of production that we maintain at our mills and our use of a single species of tree, in contrast to pulp producers in some of the world’s major softwood pulp producing regions that mix different species, depending on availability and seasonality. Our bleached pulp is marketed under the brand names “Arauco” and “Alto Paraná,” and our unbleached pulp is marketed under the brand name “Celco.”

Prices for bleached softwood kraft market pulp produced from radiata pine normally fluctuate depending on prevailing world prices, which historically have been cyclical. The fluctuations generally depend on worldwide demand, world production capacity, business strategies adopted by major forestry, pulp and paper producers, the availability of substitutes and the relative strength of the U.S. dollar. See “Item 5. Operating and Financial Review and Prospects—Management’s Discussion and Analysis of Financial Conditions, Results of Operations and Cash Flows—Overview” and “—Pulp Prices.”

In accordance with customary pulp market practice, we do not have long-term sales contracts with our customers (except for in a few limited cases); rather we maintain long-standing relationships with our customers with whom we periodically reach agreements on specific volumes and prices. We have a diversified customer base located throughout the world and totaling, as of December 31, 2012, more than 424 customers. As of December 31, 2012, we employed 14 sales agents to represent us in more than 40 countries. We manage this worldwide sales network from our headquarters in Chile.

Panels

Our panel products consist of plywood and fiberboard panels. For the year ended December 31, 2012, sales of panels were U.S.$1,320.5 million, representing 30.8% of our total sales revenues.

Exports, which include sales to countries other than the countries in which the goods are produced, accounted for 36.0% of our total sales revenues of panels for the year ended December 31, 2012. We sell panels primarily to customers in North America, Europe, Brazil, Chile, Argentina and other countries in Latin America.

The following table sets forth, by category, our panel sales to unaffiliated third parties for each of the years indicated.

	(in thousands of cubic meters)
Total Panels		2,353		2,630		3,032		3,222		3,555

As of December 31, 2012, we owned and operated three panel mills in Chile, two in Argentina, two in Brazil, six in the United States and two in Canada, with an aggregate installed annual production capacity of approximately 5,743,000 cubic meters. Two recent acquisitions expanded our North American manufacturing presence. In December 2011, Arauco Panels USA, one of our U.S. subsidiaries, entered into an asset purchase agreement to acquire an industrial facility in Moncure, North Carolina for U.S.$56 million plus approximately U.S.$6 million in working capital, subject to adjustment based on actual working capital at closing. In June 2012, we entered into a share purchase agreement to acquire five panel mills in the United States, located in Albany, Oregon; two in Bennettsville, South Carolina; Eugene, Oregon; and Malvern, Arkansas, and two panel mills in Canada, located in St. Stephen, New Brunswick and Sault Ste. Marie, Ontario for a total purchase price of U.S.$242.5 million.

The following table sets forth, by category, our wood products sales to unaffiliated third parties for each of the periods indicated:

	Year ended December 31,
	2008		2009		2010		2011		2012
	(in thousands of cubic meters)
Sawn timber		2,522		1,952		2,098		2,181		2,100
Remanufactured wood products		348		279		316		363		413

Aserraderos Arauco S.A. was established in 1993 to centralize management and control production in our sawmill and remanufacturing operations.

As of December 31, 2012, we had nine sawmills in operation, eight in Chile and one in Argentina, with an aggregate installed annual production capacity of approximately 2.8 million cubic meters of lumber. We operate our sawmills in coordination with our forestry and sales operations, since our sawn timber is generally produced in accordance with customer specifications. All of our sawmills are located near our pine plantations. As of December 31, 2012, we also own five remanufacturing facilities, four in Chile and one in Argentina, that reprocess sawn timber into remanufactured wood products, such as moldings, jams and pre-cut pieces that end users require for doors, furniture and door and window frames. These facilities produced 347,910 cubic meters of remanufactured wood products in 2012.

38

During 2008, the decrease in demand of sawn timber products, due primarily to the credit crisis and the continued downturn in the real estate market in the United States, resulted in our decision to close the following facilities (indicating the date of closure and the annual lumber production capacity of each facility):

• the Arapoti sawmill (closed on March 31, 2008 with an annual production capacity of 250,000 cubic meters),

• the Lomas Coloradas sawmill (closed on August 9, 2008 with an annual production capacity of 250,000 cubic meters),

• the Coronel sawmill (closed on November 17, 2008 with an annual production capacity of 150,000 cubic meters, which was sold in June, 2010), and

• the Coelemu sawmill (closed on December 30, 2008 with an annual production capacity of 80,000 cubic meters).

In November 2009 production at the Horcones II sawmill was suspended. However, due to favorable market conditions and in order to restore jobs in a region that was seriously affected by the earthquake that occurred in Chile on February 27, 2010, Horcones II sawmill resumed operations in June 2010 with an annual production capacity of 225,000 cubic meters.

On July 1, 2012, we commenced the process of insourcing the operation of 13 sawn timber industrial facilities, which had previously been managed by third-party companies. In the process, we incorporated 2,900 people into the Arauco workforce.

The following is a brief description of our sawmills and remanufacturing facilities and their production capacity, as of December 31, 2012.

Forestry Products

Our forestry products are sawlogs, pulplogs, posts and chips. As a result of our forest management policies and the increasing maturity of our plantations, our plantations are yielding increasing volumes of forestry products, particularly clear wood. As the volume of clear wood has grown, we have broadened our range of forestry products. For the year ended December 31, 2012, sales of forestry products were U.S.$149.9 million, representing 3.5% of our sales revenues for such year.

The following table sets forth, by category, forestry product sales to unaffiliated third parties for each of the years indicated.

Sustainable Development

We utilize renewable fuels such as forest biomass residue in power plants that cogenerate the steam and electricity required for our manufacturing operations, thus contributing to reduce greenhouse emissions. Biomass co-generation allows for a high thermal efficiency, approaching 80% in some cases. In addition to meeting our own energy needs, we generate a significant amount of surplus power, which we deliver to the Chilean power grid (Sistema Interconectado Central, or SIC), which distributes electrical power throughout the Central and Southern Regions of Chile.

As of December 31, 2012, we had registered five electricity co-generation power plants as projects of the Clean Development Mechanism (CDM) within the Kyoto Protocol. Three of them were registered during 2006—Trupán, Nueva Aldea (first phase) and Nueva Aldea (second phase)—, a fourth one was registered in 2009, the Valdivia biomass power plant, and the fifth one was registered in January 2011, the Horcones power plant expansion project. Each of these power plants generates electricity through forestry biomass (meaning forestry and wood

industrial sub-products, including the woodpulp by-product called “black liquor”), which is a renewable carbon-neutral fuel that allows the facilities to significantly decrease their reliance on the more fossil-fuel intensive grid electricity.

In connection with the CDM, we have issued to date a total (net) amount of 1,702,984 Certificates Emission Reductions (CERs or “carbon credits”) over the last 6 years, and we were the first Chilean forestry company to issue CERs through the CDM of the Kyoto Protocol. Of the total amount issued, we have sold 1,070,787 CERs. The following table presents the total amount of CERs issued and sold by Arauco for each of the years indicated:

	Year ended December 31,
	2007		2008		2009		2010		2011		2012
CERs issued (net, after commission paid to United Nations Framework Convention on Climate Change)		482,129		255,592		333,067		0		0		632,197
CERs sold		482,129		255,592		333,067		0		0		0

During the first half of 2012, we started the Viñales biomass power plant, which is located alongside the Viñales sawmill in the Seventh Region of Chile. The plant includes a biomass-fueled power boiler with capacity to produce 210 tons of steam per hour and a 41 Megawatt co-generating steam turbine. The plant began operations on May 17, 2012, attaining its maximum production capacity of 41 Megawatts on August 29, 2012.

During January 2013, the biomass cogeneration power plant associated with the Punta Pereira pulp mill facility in Uruguay was successfully registered as a CDM project activity. This constitutes the eleventh CDM project activity to be registered in Uruguay to date. Once in operation, this facility will generate an average of 124,000 CERs throughout its first 7-year crediting period.

During the second half of 2011, we completed the second Carbon Footprint calculation for Arauco’s 2010 greenhouse emissions. This excercise corresponds to Arauco’s strategy of assessing the impact of its industrial operations, in particular with respect to climate change. The Company believes these calculations will be a valuable input in the process of establishing a carbon management policy in the future.

Competition

We experience substantial worldwide competition in each of our geographical markets and in each of our product lines.

Pulp

In general, our competitors in the pulp market vary depending on the geographical region and variety of pulp involved. CMPC Celulosa S.A. and Fibria Cellulose S.A. are our main competitors in most geographical regions. While Fibria produces hardwood pulp only, CMPC produces both softwood and hardwood pulp. In Asia, we also face competition from Canadian, Brazilian, Russian and Indonesian producers. In Europe, we also face competition from Brazilian, Scandinavian and American producers. Our main competitors with respect to unbleached softwood pulp are from Canada and Russia.

Panels

Arauco’s principal competitors in the plywood markets are located in the United States, Finland and Russia. In some regions, Arauco also competes with hardwood plywood produced in China, Africa and other regions of the world.

Arauco’s main competitors in the MDF market are: in Latin America, Duratex S.A., Masisa S.A. and other large South American producers; in North America, local producers such as Roseburg Forest Products Co.; in Asia, producers from Malaysia and China, and in the Middle East, European producers.

41

For sales of PBO, in the Latin American market we compete with Duratex S.A., Masisa S.A., Berneck S.A. and Fibraplac S.A. In North America we mainly compete with Roseburg Forest Products Co. Temple Inland, Kaycan and Sonae.

Wood Products

For remanufactured wood products, our main competitors are located in Chile, Brazil, and the United States. For sawn timber, our main competitors are located in Europe, New Zealand, Canada, and Chile. We believe that our operating efficiencies, competitive logistics costs, ability to serve customers with multiple specifications, geographical presence in thirty eight countries and the versatility of our radiata and taeda pine allow us to compete effectively in the world market for wood products.

Transportation, Storage and Distribution

To remain competitive worldwide, we ship our products to various distribution centers around the world from which final delivery to the customer is made. Historically, we and other Chilean forestry products producers have coordinated our transportation requirements to achieve larger lots to fill specially designed forestry products ships and thus obtain competitive freight rates.

The following are the principal Chilean ports that we use, each of which are operational as of the date of this annual report:

• Coronel. A private port located between Concepción and the Arauco Mill, which we constructed as a member of a consortium with five other companies and in which we have an equity interest of 50%. We shipped 31% of our aggregate export volume through this port in 2012;

• Lirquén. A private port in Concepción in which we have an equity interest of 20.2% and through which we shipped 29% of our aggregate export volume during 2012; and

• San Vicente. State-owned port near the city of Concepción through which we shipped 40% of our aggregate export volume during 2012.

The ports we use in Chile are approximately 60 kilometers from the Arauco Mill, 310 kilometers from the Constitución Mill, 370 kilometers from the Licancel Mill, 70 kilometers from the Nueva Aldea Mill, and 430 kilometers from the Valdivia Mill. We do not own pulp storage warehouses in any of these ports.

We ship pulp to various ports in Europe, North and South America and Asia and, as is customary in the pulp industry, we store some stock in those ports. We use 12 foreign ports that have warehouse facilities available, and standard storage terms provide that we are entitled to a certain period of storage free of charge. We seek to ensure that we do not exceed the free storage period for each shipment. As of December 31, 2012, we had approximately 74,000 air dry tonnes of pulp in storage in warehouses at foreign ports.

We believe that our shipping costs are comparable to those of our international competitors, notwithstanding Chile’s greater distance from Europe, because of the proximity of our plantations and mills to the Pacific coast and the economies of scale we achieve through the volume of our exports.

In Argentina, timely and competitively priced delivery of finished products to our customers is an important factor in our ability to compete effectively, and we ship most orders either by truck or railway almost immediately after they are produced.

In Brazil, our efficient distribution system, which delivers finished products to almost two thousand customers in over 450 cities, many of which are separated by long distances, is a key component to our competitiveness.

42

In North America, products sourced from our Chilean operations are shipped into 12 major ports of entry and are dispatched to more than 2,800 locations in the U.S. and Canada. Flakeboard’s seven plants service over 450 customers throughout North America, in addition to exporting products to the Caribbean, Central America and the Middle East.

Description of Property

Our principal properties consist of land and production plants and facilities, the majority of which are located in Chile. As of December 31, 2012, we owned 1,115,237 hectares of land in Chile, of which 736,637 hectares are forest plantations, and 580,485 hectares of land in Argentina, Brazil and Uruguay, of which 302,565 consist of forest plantations. In addition, as of December 31, 2012, we owned and operated various plants and facilities, including five pulp mills, three panel mills, eight sawmills and four remanufacturing facilities in Chile; one pulp mill, one sawmill, one MDF mill, one PBO mill, one chemical plant and one remanufacturing facility in Argentina; one MDF mill and one MDF-PBO mill in Brazil; two PBO mills, three MDF mills and one MDF-PBO mill in the United States; and one MDF mill and one PBO-MDF mill in Canada. Future expansion plans will depend on global market conditions. Arauco does not currently have near-term expansion plans. For information regarding environmental risks associated with our use of our properties, see “Item 3. Key Information—Risk Factors—Risks Relating to US and the Forestry Industry.”

Insurance

Consistent with industry practice, we maintain fire insurance coverage for all our Chilean forest holdings and nurseries but do not insure against pests or disease. Depending on the age of the trees affected, our insurance covers timber loss, either at replacement cost or commercial value. In Argentina we maintain fire insurance for 11,983 hectares of timber assets located in Delta del Paraná, near Buenos Aires. For the rest of our Argentine operations we do not maintain fire insurance for our timber assets because we believe that the risk of damage from fire is low because Argentina receives significant amounts of rainfall, particularly during the summer months. We do not carry fire insurance for our forests in Brazil because the risk of damage from fire does not justify the costs of carrying insurance.

We also carry insurance, consistent with industry practice, covering our production plants, facilities and equipment. This insurance provides coverage, in the event of fire, explosion, machinery breakdown or natural disasters, including earthquakes and tsunamis. The insurance covers up to an amount of U.S.$650 million per loss, which includes physical damage and business interruption of up to 12 months (or 18 months in the case of a boiler explosion in our pulp mills). The deductibles for physical damage are U.S.$3 million for damages caused by earthquakes and tsunamis, with a deductible of 2% of the insured amount for each location subject to a cap of U.S.$25 million. Deductibles for business interruption are 30 days for all losses, 45 days for machinery breakdown and 60 days for machinery breakdown of turbines. We also have an annual self-insurance retention of U.S.$20 million, with a U.S.$10 million maximum per event. All of our insurance policies covering our production plants, facilities and equipment in Chile and Argentina are carried by the RSA group, Mapfre S.A. and Ace Group.

As described in more detail in “Item 3. Key Information—Risk Factors—We are located in a seismic area that exposes our property in Chile to the risk of earthquakes, and we experienced significant business disruption and losses as a result of the February 27, 2010 earthquake,” we suffered significant earthquake-related damage to property and inventories as well as a significant decrease in our sales volumes due to the February 27, 2010 earthquake in Chile. On November 15, 2011, we and the insurers accepted the final report of the insurance adjusters. In accordance with such final report, as of December 31, 2012, we received a total recovery of U.S.$532 million.

As described in more detail in “Item 3. Key Information—Risk factors–Disease or fire could affect our forests and manufacturing processes and, in turn, adversely affect our business, financial conditions, results of operations and cash flows,” our Nueva Aldea Complex suffered significant fire-related damage to our plywood mill and forests due to wildfires that affected the Eighth Region of Chile. Our insurance covered the losses related to our forest plantations. We paid a U.S.$1.0 million deductible for business interruption and property damage at our Nueva Aldea plywood mill. On December 11, 2012, we and the insurers accepted the final report of the insurance adjusters. In accordance with such final report, as of December 31, 2012, we received a total recovery of U.S.$143.0 million, net of U.S.$110.0 million in advance payments that we had already received. With respect to our inventory, which was covered under a different policy, and we received during 2012 a total recovery of U.S.$22.0 million.

43

The forestry insurance for plantations located in Chile is carried by the RSA Group and Penta Security Compañía de Seguros S.A. Our insurance policies for some plantations located in Delta del Paraná, Argentina, are carried by Federación Patronal. Our MDF and particleboard mills in Brazil are insured by Itaú XL Seguros Corporativos and Allianz Seguros S.A., and these policies cover fire, explosions, electrical damage, equipment damage and loss of profit. For more information regarding the risks for which we insure our property, see “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry.”

CAPITAL EXPENDITURES

To utilize our increasing volume of forest production, we have added to, expanded and modernized our processing facilities. For the year ending December 31, 2013, we have planned capital expenditures of U.S.$498.5 million, which principally include U.S.$309.2 million in maintenance of our existing mills, U.S.$72.0 million in capital contributions to the Montes del Plata joint venture in Uruguay and U.S.$117.3 million in maintenance and acquisition of biological assets.

On January 18, 2011 Arauco and Stora Enso agreed to carry out the construction of a state of the art pulp mill with an annual guaranteed capacity of 1.3 million tons, a port and a power producing unit based on renewable sources, all located in Punta Pereira, department of Colonia, Uruguay. The total estimated investment is U.S.$2,000.0 million. For more information regarding the ongoing construction of the pulp mill in Uruguay, see “Item 3. Key Information—Risk Factors—Risks Relating to Uruguay—Risks relating to Uruguay—Economic conditions in Uruguay may have a direct impact on our financial condition and results of operations.”

For the year ended December 31, 2012, our aggregate capital expenditures were U.S.$628.6 million, consisting primarily of U.S.$506.0 million in internal projects and U.S.$122.6 million in acquisition of biological assets.

For the year ended December 31, 2011, our aggregate capital expenditures were U.S.$748.3 million, consisting primarily of U.S.$602.4 million in internal projects and U.S.$145.9 million in acquisition of biological assets.

For the year ended December 31, 2010, our aggregate capital expenditures were U.S.$595.5 million, consisting primarily of U.S.$483.2 million in internal projects and U.S.$112.3 million in acquisition of biological assets.

GOVERNMENT REGULATION

Environmental Regulation

In each country where we have operations, we are subject to numerous national and local environmental laws, regulations, decrees and municipal ordinances concerning, among other things, health, the handling and disposal of solid and hazardous waste, discharges into the air, soil and water and other environmental impacts. Some of these laws require us to conduct environmental impact studies of future projects or activities (or major modifications thereto). Under these laws, our operations may be subject to specific approvals, consents and regulatory requirements, and emissions and discharges may be required to meet specific standards and limitations. We have made and will continue to make substantial expenditures to comply with such environmental laws, regulations, decrees and ordinances.

Chile

The Chilean legislation to which we are subject includes the Chilean Environmental Law (Ley Sobre Bases Generales del Medio Ambiente) and related regulations. The Chilean Environmental Law created the National Environmental Commission (Comisión Nacional del Medio Ambiente), or CONAMA, which includes under its organization the various Regional Environmental Commissions (the COREMAs). As discussed below, these institutions were replaced in 2010 by the Ministry of Environment, the Service of Environmental Evaluation and the Evaluation Commissions (Comisiones de Evaluación) and a new Superintendency of Environment.

44

The Ministry of the Environment is under the direct supervision of the President of Chile and it is responsible for, among other things, creating and/or proposing environmental public policies and environmental regulations. The Service of Environmental Evaluation and the Evaluation Commissions administer the Environmental Impact Evaluation System (“SEIA”) and evaluate environmental impact studies or declarations of environmental impact. Under the Chilean Environmental Law, we are required to conduct environmental impact studies or declarations of environmental impact of any future projects or activities (or their significant modifications) that may affect the environment. These and other regulations also establish procedures for private citizens to object to the plans or studies submitted by project owners.

Governmental agencies may participate in the oversight of the implementation of projects in accordance with their environmental impact studies or declarations of environmental impact. Under the Chilean Environmental Law and other regulations, affected private citizens, public agencies and local authorities can sue to enforce environmental compliance. Enforcement remedies include temporary or permanent closure of facilities and fines. The application of these environmental laws and remedies may adversely affect the manner in which we seek to implement our business strategy and our ability to realize our strategy.

On January 26, 2010, Law No. 20,417 was published in the Official Gazette. This new law replaced the former CONAMA and COREMA with a new set of public institutions: the Ministry of the Environment (aimed at developing national environmental policy), the Service of Environmental Evaluation (in charge of administering the environmental assessment system) and the Superintendency of Environment (in charge of supervising and auditing environmental compliance). On October 1, 2010, the Ministry of the Environment, the Service of Environmental Evaluation and the Evaluation Commissions began operating under their full legal authority. In addition, on June 28, 2012, Law No. 20,600 was published in the Official Gazette. This law established three environmental tribunals whose purpose is to resolve environmental conflicts. Each tribunal presides over a defined territorial jurisdiction. The Second Environmental Tribunal became operational on December 28, 2012. The First and Third Environmental Tribunals will become operational 12 months after the date on which Law No. 20,600 was published. When the Second Tribunal became operational, the provisions of Law No. 20,417 entered into full force, allowing the Superintendency of Environment to exercise its full legal powers. The Superintendency has issued numerous resolutions, instructions and requirements with respect to officials and supervised parties.

We recently faced, and continue to face, certain environmental proceedings in connection with certain of our pulp mills. For a description of these proceedings, see “Item 8. Financial Information Legal Proceedings.”

Argentina

Our operations in Argentina are subject to Argentine environmental legislation, including regulation by municipal, provincial and federal governmental authorities.

Argentine environmental legislation includes the requirement that water used or recovered in the production process has to be chemically, biologically and thermally treated before being returned to public waters, such as the Paraná River. In addition, all gaseous emissions must be scrubbed to ensure satisfactory levels of waste particle recovery and odor removal. Regular testing of river water and air quality is used to monitor the ultimate impact of the mill on the environment.

We believe that we are currently in material compliance with all applicable local and national environmental regulations governing our operations in Argentina.

Brazil

Our Brazilian operations are subject to environmental legislation, including municipal, regional and federal governmental laws, regulations and licensing requirements. Law No. 6,938 establishes strict liability for environmental damage, mechanisms for enforcement of environmental standards and licensing requirements for activities that are damaging or potentially damaging to the environment. A violation of environmental laws and regulations may result in:

• fines,

45

• partial or total suspension of activities,

• forfeiture or restriction of tax incentives or benefits, or

• forfeiture or suspension of participation in credit lines with official credit establishments.

As a result, we may become liable for environmental damages caused by management of our materials, including damages caused during the transportation, treatment and disposal of our industrial waste, even where third parties manage such activities on our behalf.

Law No. 9,605 provides that individuals or entities whose conduct or activities cause harm to the environment are subject to criminal and administrative sanctions and are liable for any costs to repair the damages resulting from such harm. For individuals who commit environmental crimes, criminal sanctions range from fines to imprisonment; for legal entities, criminal sanctions may include fines, partial or total suspension of activities, restrictions on participation in government contracts and, in cases of bad faith, dissolution. In addition, Law No. 9,605 also establishes that the corporate structure of a company may be disregarded if the structure impedes the recovery for harm caused to the environment. We are not aware of any successful assertion of claims against shareholders under this provision of Law No. 9,605.

We believe we are currently in material compliance with all applicable local and national environmental regulations governing our operations in Brazil.

Uruguay

The activities of the Montes del Plata joint venture in Uruguay are subject to Uruguayan national and municipal environmental regulations. The principal environmental authorization required to carry out such project’s current activities is the environmental authorization, or AAP, regulated by the Environmental Impact Assessment Act, Law Nº 16.466, and its regulatory decree Nº 349/005. The AAP is granted by the National Environmental Bureau, or DINAMA, which pertains to Ministry of Housing, Land Use Management and Environment, or MVOTMA. In order to obtain this authorization, an applicant must submit a complete report regarding all aspects of the proposed works including a classification of the same by a competent professional in one of the three categories, A, B or C. If the proposed project is classified as B or C, a comprehensive environmental impact assessment (which includes all aspects of the project, including water and noise, among others) is required and in some cases a public hearing may be required. Once the AAP is granted, the interested party is required to perform the project in accordance with the terms and conditions of such authorization.

For certain activities (including construction of an industrial plant) listed in Article 2 of Decree 349/005, a Viability Location Report, or “VAL”, is required. This report must include a notification to the municipal government where the project is to be located (“Intendencia”) and the delivery of information similar to that required for the AAP. This process contemplates a period for the public of summary information that is available. The Intendencia involved in any such project may submit its findings to the DINAMA for consideration. The VAL, if needed, must be obtained prior to the AAP. The relevant companies that comprise our Montes del Plata joint venture have already obtained the AAP and the VAL. We believe that the Montes del Plata project is currently in material compliance with applicable local and national environmental regulations in Uruguay.

United States and Canada

Our North American operations are subject to U.S. and Canadian environmental legislation, including federal, provincial, state and local laws and regulations. Such laws and regulations govern the use, storage, handling, generation, treatment, emission, release, discharge and disposal of certain hazardous materials and wastes,

46

the remediation of contaminated soil and groundwater, plant and wildlife protection, landfill sites and the health and safety of employees. For example, under the Clean Air Act, the United States Environmental Protection Agency (“EPA”) has established Maximum Achievable Control Technology (“MACT”) environmental regulations that establish emission standards for point sources of pollution, such as process vents and equipment leaks. In addition, some of our operations require environmental permits and controls to prevent and reduce air and water pollution. Our failure to comply with applicable environmental, health and safety requirements, including permits related thereto, may result in:

• fines,

• enforcement actions or other sanctions, such as judicial orders enjoining or curtailing operations or requiring corrective measures,

• loss of operating permits,

• required installation of pollution control equipment, or

• remedial actions.

In addition, we may become liable under third-party claims for personal injury and property damage due to contamination at our mills, even where the activity that caused such contamination occurred before we owned the mills.

We believe we are currently in material compliance with all applicable local and national environmental regulations governing our operations in the United States and Canada.

Forestry, Land-Use and Land Ownership Regulations

Chile

The management and exploitation of forests in Chile is regulated by the Forests Law of 1931, as amended, and Decree-Law No. 701 of 1974, as amended. The Forests Law and Decree-Law No. 701 impose a variety of restrictions on the management and exploitation of forests. Forestry activities, including thinning, on land that is designated as preferably suited for forests or that has natural or planted forests, are subject to management plans that require the approval of the Corporación Nacional Forestal, or “CONAF” (National Forest Service). In addition, the Forests Law and Decree-Law No. 701 impose certain standards for the prevention of forest fires, as well as fines for the harvesting or destruction of trees and shrubs in violation of the terms of a forest management plan. We believe that we are in material compliance with the Forests Law and Decree-Law No. 701.

Law No. 20,283, published in the Official Gazette on July 30, 2008, provides for the management and conservation of native tree forests and forest development. Its purposes are the protection, recovery and improvement of native forests in order to guarantee both forest sustainability and environmental policy. This law established a fund for the conservation and sustainable management of native forests. According to this law, owners of native forests are able to exploit them so long as they have a “management plan” approved by the CONAF. Depending on the owner’s approved plan, as well as other factors, the subsidy provided by the fund may vary between U.S.$200 and U.S.$400 per hectare. The law also prohibits the harvesting of native trees in certain areas and under certain conditions. In compliance with applicable regulations, we have adopted environmentally sensitive policies towards our holdings of native forests, which are protected and preserved in their entirety. Our products come from established plantations only; we do not sell any products derived from our native forests. Arauco’s forestry operations adhere to our international control systems, which are all in accordance with current legislative and environmental sustainability standards. We believe that we are in material compliance with Law No. 20,283. See “Item 4. Description of Business—Forestry Activity.”

47

Argentina

The management and exploitation of forests in Argentina is regulated by National Law 13,273, National Law 25,080, and National Law 26,432, National Decree 710, Provincial Law No. 854, Provincial Law No. 3,426 and other regulations promulgated thereunder, which collectively constitute the regulatory framework. The regulatory framework imposes a variety of restrictions on the management and exploitation of forests in Argentina. The regulatory framework regulates the replanting of land after harvesting.

On December 28, 2011, National Law 26,737 was promulgated, which established limitations on the ability of foreigners to purchase rural land in Argentina. This law provides that foreigners cannot acquire more than 15% of all rural land in the country, and that no foreigner can, individually, hold more than 30% of said 15%. For the purposes of the National Law 26,737, rural land is all land located outside the urban area.

We believe that our Argentine operations are in material compliance with the regulatory framework.

Brazil

Environmental laws and regulations relating to the management and exploitation of forests and the protection of Brazilian plant and wildlife govern our Brazilian forestry operations. Under this regulatory framework Brazilian authorities establish forest preservation areas and regulate replanting of forests after harvesting.

There are currently certain Brazilian legal restrictions on the acquisition of rural properties by foreign companies or by Brazilian companies controlled by foreign persons. Those restrictions are contained in Federal Law No. 5,709/1971 and in the recent Opinion issued by the Office of the General Counsel to the Federal Government in August, 2010.

We believe that our Brazilian operations are in material compliance with the regulatory framework.

Uruguay

The management and exploitation of forests in Uruguay is regulated primarily by Law 15,939, which has declared forestry activity as an area of national interest. This law classifies forests into three categories: protectors, yield and general, and provides certain tax and financial benefits related to forests classified as protectors and yield. In order to obtain such classification, interested parties have to submit a forestry plan report before the General Forestry Bureau. This law also establishes certain conservation restrictions and controls for each category of forest.

Additionally, forest activity is subject to environmental and soil care regulations. According to Law 16.466 and decree 349/005, plantations of more than 100 hectares need prior environmental authorization. Law Nº 15.239 also provides certain measures that must be adopted to reduce erosion and degradation of the soil or to restore soil when necessary.

We believe that the forestry operations of the Montes del Plata joint venture are in material compliance with the applicable regulatory framework.

Item 5. Operating and Financial Review and Prospects

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION, RESULTS OF OPERATIONS AND CASH FLOWS

The following discussion is based on and should be read in conjunction with our audited consolidated financial statements and the notes thereto, included elsewhere in this annual report. Our consolidated financial statements are prepared in U.S. dollars in accordance with IFRS.

48

Overview

We derive our sales revenue from the sale of bleached and unbleached pulp, panels, wood products such as sawn timber and remanufactured wood products, and forestry products such as sawlogs and pulplogs. Export sales constituted 71.5% of our total sales revenue for the year ended December 31, 2011, and 66.1% of our total sales revenue for the year ended December 31, 2012. Sales of pulp constitute the single largest component of our sales revenue. As with many commodities, pulp is subject to significant cyclical price fluctuations determined by global supply and demand. Accordingly, our sales revenue is subject to cyclical fluctuations. World prices for panels, wood products and forestry products, which are generally viewed as commodities, also fluctuate significantly. Although prices tend to have the most significant effect on our results of operations, sales volume and product mix, production costs and exchange rate fluctuations also can have a substantial impact on our results.

Our business, results of operations and cash flows depend, to a large extent, on the level of economic activity, on government and foreign exchange policies and on political and economic developments in our principal export markets. In 2012, we exported our products to Asia, to North, Central and South America, to Europe and, to a lesser extent, to Africa and the Middle East. In 2011 and 2012, 94.4% and 93.3%, respectively, of our total pulp sales were attributable to exports, and 54.9% and 49.1%, respectively, of our total panels, wood products and forestry product sales were attributable to exports. Our business, earnings and prospects may be materially and adversely affected by developments in these export markets with respect to inflation, interest rates, currency fluctuations, protectionism, government subsidies, price and wage controls, exchange control regulations, taxation, expropriation or social instability, as well as by political, economic or diplomatic developments.

As of December 31, 2012, 73.6% of our property, plant, equipment and forest assets were directly owned by the Company and our Chilean subsidiaries, 10.4% by our Argentinean subsidiaries, 11.8% by our Brazilian subsidiaries, 4.2% by our U.S. and Canadian subsidiaries. In 2012, 73.3% of our consolidated sales revenue was derived from our operations in Chile, 11.1% of our consolidated sales revenue was derived from our operations in Argentina, 9.8% of our consolidated sales revenue was derived from our operations in Brazil, and 5.8% of our consolidated sales revenue was derived from our operations in the United States and Canada. Accordingly, our financial condition, results of operations and cash flows depend, to a significant degree, upon economic conditions in Chile, Argentina, Brazil, the United States and Canada.

Effects of February 27, 2010 Earthquake in Chile

On February 27, 2010, an earthquake measured at a magnitude of 8.8 on the Richter scale, followed by a tsunami, occurred off the coast of the South-Central Region of Chile, an area where we maintain a substantial portion of our industrial operations in Chile. Immediately after the earthquake, all of our production units applied their contingency plans which involved shutting down operations and evaluating the damage caused to each facility by the earthquake. Our operations that had been affected by the earthquake and tsunami reopened gradually in connection with our repair efforts and the improvement of external factors, such as infrastructure conditions, road connectivity, power supply and public safety concerns. As of December 31, 2012, all of our operations have reopened and were operating at full operational capacity except for our Mutrún Sawmill, which was destroyed and will not be reopened. The Mutrún sawmill represented approximately 6% of our sawn timber production capacity in Chile.

The following table sets forth the number of days that each of our facilities in Chile was closed due to the earthquake in Chile.

The suspension of our operations in Chile resulted in significant asset impairment charges due to earthquake-related damage to property and inventories as well as a significant decrease in our sales volumes due to plant closures, which had an adverse effect on our results of operations and cash flows. Our insurance policies provide coverage for damages to our property, plant, equipment and inventories and for business interruption caused by such damages up to an aggregate amount of U.S.$650 million, with a deductible of U.S.$3 million for property damage and a deductible of 21 days for business interruption. On November 15, 2011, we and the insurers accepted the final report of the insurance adjusters. In accordance with such final report, as of December 31, 2012, we received a total recovery of U.S.$532.0 million. See “Item 4. Information on the Company—Description of our Business—Insurance.”

Effects of January 2012 Wildfires

Commencing on December 31, 2011, wildfires, exacerbated by high temperatures and strong winds, broke out in the Eighth Region of Chile. As a result, the fires destroyed our Nueva Aldea plywood mill and approximately 8,200 hectares of our forest plantations. The affected forest plantations represented approximately 0.8% of our total forest plantations. Our Nueva Aldea plywood mill, which represented a cash investment of approximately U.S.$110 million, had an annual production capacity of 450,000 cubic meters, representing approximately 14.2% of our total panel production capacity at that time. Although the plywood mill at Nueva Aldea and our forest plantations were insured, our insurance was subject to deductibles and caps, including a 15-day deductible relating to our business interruption insurance for the Nueva Aldea plywood mill. See “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry—Disease or fire could affect our forests and manufacturing processes and, in turn, adversely affect our business, financial condition, results of operations and cash flows.”

Economic Indicators in Chile, Argentina, Brazil, Uruguay, the United States and Canada

Chile

The Chilean GDP increased by 5.6% in real terms during 2012, compared to a growth rate of 5.9% in 2011 and 5.8% in 2010. See “Item 3. Key Information—Risk factors—Risks relating to Chile.”

50

Argentina

From late 1998 to 2002, the Argentine economy went through an economic recession marked by reduced levels of consumption and investment and an elevated unemployment rate. Argentine GDP decreased by 0.8% in 2000, 4.0% in 2001 and 10.9% in 2002. In December 2001, amid public demonstrations and the resignation of the Argentine president, Argentina declared a suspension on payment of its foreign debt. In early 2002, the government released the Argentine peso from its one-to-one peg to the U.S. dollar and allowed the exchange rate to float, resulting in a 49.6% devaluation of the Argentine peso from January 1, 2002 to December 31, 2002. From 2003 to 2008, economic indicators showed signs of recovery, and the Argentine GDP increased by 8.8% in 2003, 9.0% in 2004, 9.2% in 2005, 8.5% in 2006, 8.7% in 2007 and 6.8% in 2008. Due to the global financial crisis, Argentina’s GDP grew by only 0.9% in 2009. In 2010, Argentina’s GDP growth rose to 9.2%, and in 2011and 2012 it grew at rates of 8.9% and 1.9%, respectively. The future economic, social and political developments in Argentina, over which we have no control, could impair our and Alto Paraná’s business, financial condition or results of operations. See “Item 3. Key Information—Risk factors—Risks relating to Argentina.”

Brazil

Brazil’s GDP increased by 0.9% in real terms during 2012, compared to growth rates of 2.7% in 2011 and 7.5% in 2010. In 2010, the real appreciated against the dollar by 4.5% and in 2011 and 2012 the real depreciated against the dollar by 11.2% and 8.2%, respectively. See “Item 3. Key Information—Risk factors—Risks relating to Brazil.”

Uruguay

Uruguay GDP increased by 3.9% in real terms during 2012, compared to growth rates of 5.7% in 2011 and 8.9% in 2010. In 2010 and 2011, the Uruguayan peso depreciated against the dollar by 1.8% and 1.3%, respectively, and in 2012 the Uruguayan peso appreciated against the dollar by 3.8%. See “Item 3. Key Information—Risk factors—Risks Relating to Uruguay.”

United States

The United States GDP increased by 2.2% in real terms during 2012, compared to growth rates of 1.8% in 2011 and 2.6% in 2010. See “Item 3. Key Information—Risk factors—Risks Relating to the United States.”

Canada

Canada’s GDP increased by 3.0% in real terms during 2012, compared to a growth rates of 5.5% in 2011 and 6.0% in 2010. In 2010, the Canadian dollar appreciated against the U.S. dollar by 5.2%, in 2011 the Canadian dollar depreciated against the U.S. dollar by 2.1% and in 2012 the Canadian dollar appreciated against the U.S. dollar by 2.0%. See “Item 3. Key Information—Risk factors—Risks relating to Canada.”

Exchange Rate Fluctuations

The Chilean peso has been subject to devaluation in the past and could be subject to significant fluctuations in the future. During 2012, the value of the Chilean peso relative to the U.S. dollar increased 7.6% in nominal terms and 6.0% in real terms, based on the observed exchange rates on December 31, 2011 and December 31, 2012. The observed exchange rate on April 29, 2013 was Ch$472.05 to U.S.$1.00. For information regarding historical rates of exchange in Chile from January 1, 2008, see “Item 3. Key Information—Exchange Rates.”

Prices

We generally price our exports in U.S. dollars, whereas our domestic sales in Chile are priced in Chilean pesos; domestic sales in Brazil are priced in reals and domestic sales in Argentina are priced in Argentine pesos except for pulp sales, which are priced in U.S. dollars. To the extent that the Chilean peso depreciates against the U.S. dollar, our domestic sales revenues may be adversely affected when expressed in U.S. dollars. The same effects may occur for our domestic sales in Argentina and Brazil for products sold in each of the respective local currencies. The effect of exchange rate fluctuations is partially offset by the fact that certain of our operating expenses are denominated in U.S. dollars (such as our freight costs and selling expenses in the form of

51

commissions paid to our sales agents abroad) and a significant part of our indebtedness is denominated in U.S. dollars. As of December 31, 2012, our U.S. dollar-denominated indebtedness was U.S.$3,322.7 million. In addition, as the U.S. dollar appreciates against the local currency in any of our export markets, we must from time to time price our sales in that local currency to compete effectively.

During the last quarter of 2008, the prices of our products decreased substantially as a result of the global financial crisis. Prices began to show a slight recovery during the second quarter of 2009. The recovery in the pulp market was confirmed during the fourth quarter of 2009 and the year 2010, during which time pulp prices grew strongly, reaching near pre-crisis levels and continued at high levels during the first half of 2011. In the second half of 2011, pulp prices started to decline, reaching their lowest point at the end of the year. During the first half of 2012, pulp prices increased slightly, remaining generally stable during the second half of 2012. For additional discussion regarding recent movements in the price of pulp, see “Item 5. Operating and Financial Review and Prospects—Trend Information.”

However, future developments in the Chilean, Argentine, Brazilian, Uruguayan, Canadian and American economies may impair our ability to proceed with our strategic plan, including with respect to pricing. For additional discussion regarding the risks we face in each of the aforementioned markets, see “Item 3. Key Information—Risk Factors—Risks Relating to Chile,” “—Risks Relating to Argentina,” “—Risks Relating to Brazil,” “—Risks Relating to Uruguay,” “—Risks Relating to Canada” and “—Risks Relating to United States.”

In recent years, our sales revenue has been affected by price level volatility in the export market. The prices for each of our pulp, panels, wood and forestry products depend on the markets in which they are sold. While prices are generally similar for a given product on a global basis, regionalized market conditions affect prices in markets such as Asia, Europe and the United States.

Pulp Prices

Overview

Historically, world pulp prices have been subject to significant fluctuations over relatively short periods of time. Pulp prices mainly depend on worldwide demand, world production capacity, worldwide pulp and paper inventory levels and availability of substitutes, and in general terms, are directly related to global economic growth. All of these factors are beyond our control.

Prices for bleached grades of hardwood pulp, including eucalyptus, generally follow the same cyclical pattern as prices for Norscan Bleached Softwood Kraft market pulp, or NBSK, which is the benchmark for softwood bleached pulp. However, the latter historically has had higher prices mainly due to lower global supply. Moreover, during the last five years, the majority of the added global pulp production capacity has been dedicated to the production of hardwood pulp, particularly eucalyptus pulp.

Prices for unbleached softwood market pulp also follow cyclical patterns related to worldwide demand, stock levels and supply. Unbleached softwood market pulp represents about 3.9% of the total wood pulp market. The majority of such pulp is sold in Asia, and its price does not necessarily follow the cycle of prices for NBSK or Bleached Eucalyptus Kraft Pulp (“BEKP”).

During 2012, annual average pulp prices for all grades decreased with respect to 2011, which was mainly explained by lower demand from developed countries, and increased supply, especially from integrated European producers that added their own pulp production to the spot market. For additional discussion regarding recent movements in the price of pulp, see “Item 5. Operating and Financial Review and Prospects—Trend Information.”

Price of NBSK

The market price for NBSK was U.S.$641.51 as of December 31, 2008, a 26.2% decrease as compared to December 31, 2007. The market price of U.S.$798.77 per ton recorded as of December 31, 2009 represented an increase of 24.5% as compared to December 31, 2008. The market price for NBSK was U.S.$948.92 per ton as of December 31, 2010, an 18.8% increase as compared to December 31, 2009. The market price for NBSK was U.S.$833.71 per ton as of December 31, 2011, a 12.1% decrease as compared to December 31, 2010. The market price for NBSK was U.S.$809.6 per ton as of December 31, 2012, a 2.9% decrease as compared to December 31, 2011.

Price of BEKP

As of December 31, 2008, the market price for BEKP was U.S.$584.54, which represented a 24.6% decrease as compared to December 31, 2007. The market price for BEKP as of December 31, 2009 reached U.S.$700.00, which represented a 19.8% increase of over the price as of December 31, 2008. The market price for BEKP was U.S.$849.21 per ton as of December 31, 2010, a 21.3% increase as compared to December 31, 2009. The market price for BEKP was U.S.$651.86 per ton as of December 31, 2011, a 23.2% decrease as compared to December 31, 2010. The market price for BEKP was U.S.$775.94 per ton as of December 31, 2012, a 19% increase as compared to December 31, 2011.

Price of UKP

The market price for unbleached kraftwood pulp, or UKP, as of December 31, 2008 was U.S.$455.76, per tonne which represented a decrease of 23.8% as compared to December 31, 2007. The market price for UKP as of December 31, 2009 was U.S.$603.65 per tonne, which represented a 32.4% increase over the price as of December 31, 2008. The market price for UKP was U.S.$751.85 per tonne as of December 31, 2010, a 24.6% increase as compared to December 31, 2009. The market price for UKP was U.S.$603.65 per tonne as of December 31, 2011, a 18.9% decrease as compared to December 31, 2010. The market price for UKP was U.S.$600.3 per tonne as of December 31, 2012, a 1.6% decrease as compared to December 31, 2011.

Forestry, Wood Product and Panels Prices

Over the last five years, the average prices for our forestry, wood products and panels have fluctuated significantly, reflecting the effect on demand of global economic developments.

The slowdown in the global growth markets during 2008 negatively affected the demand for timber in all markets. The construction sector declined in the United States. In particular, the construction of houses declined to a rate of approximately 550,000 houses per year by December 2008, which negatively compares with the 2 million homes built in the United States during 2006. This decline negatively affected the sales volume and prices of wood and moldings, which reached their lowest levels during the last quarter of 2008. During most of 2008, there was a consistent demand for panels, which resulted in an increase in price in most of the products produced by Arauco. During the latter part of 2008, however, demand lowered, which negatively affected sales volume and prices of plywood and MDF in most markets, especially in the United States and Europe.

The fiscal year 2009 was challenging for the panels business due to low demand and a weak dollar. However, Arauco was able to sell all panels production without any plant shutdown despite the decline in demand. This was due to Arauco’s geographic diversification, with sales in over forty countries, and to Arauco’s broad product portfolio.

During 2010, average sales prices in our wood products segment increased as compared with 2009, mainly due to higher average sales prices of green sawn timber in the Asian market and remanufactured products in United States. Regarding our panel segment, in 2010 our sales in U.S. dollars increased by 33.5%, representing an increase of 15.3% in our average sales as compared to 2009. Average sales prices of plywood, which was the most negatively impacted product line in terms of margin erosion during 2009, increased during 2010, especially in Latin America, Europe and United States. Average sales prices of MDF, HB and MDF moldings also increased during 2010.

Although the construction and real estate market in the U.S. continued to underperform historical averages during 2011, there was a slight trend of recovery as compared with 2009 and 2010. This recovery was reflected in increased demand for wood products and price increases. In Latin America the demand for our sawn timber and panels products remained positive, which resulted in increases in sales revenue of 18.0% and 15.6%, respectively. Our sawn timber products increased in sales volume and average price by 3.9% and 9.3%, respectively. Sales revenue from our remanufactured products increased 32.4% as a consequence of a 15.1% increase in sales volume and a 15.1% in average prices. Average prices of our panels products increased 8.8%, and total sales volume increased 6.3%.

During 2012, average sales prices in our wood products segment increased as compared to 2011, mainly due to a 6.7% increase in average sales prices of sawn timber. In 2012, sales in our panel segment increased by 3.7% as compared to 2011. This increase is mainly due to a 10.4% increase in sales volume, which is partially explained by the acquisition of the Moncure mill and Flakeboard in 2012.

Prices for our panel, forestry and wood products may decline in the future. Our results of operations may be materially adversely affected if the prices of our products were to decline from current levels.

Costs

Our major costs of sales are the following:

• the cost of timber,

• costs related to harvesting (forestry works),

• maintenance costs,

54

• chemical costs,

• the cost of sawmill processing,

• depreciation, and

• energy and fuel costs.

Our major administrative and selling expenses are wages and salaries, traffic, shipping and freight costs, insurance expenses and commissions.

Our property, plant and equipment are depreciated on a straight-line basis over the remaining useful lives of the underlying assets. However, the amount of such depreciation that relates to our fixed production assets, such as pulp mills and sawmills, is allocated to finished goods held as inventories and accumulates until charged to cost of sales when the finished goods are sold. Forests and land are not depreciated. For additional information relating to the accounting treatement of our biological assets, see “—Critical Accounting Policies—Biological Assets.”

Selling expenses consist primarily of per ton fees we pay to our selling agents. Traffic, shipping and freight costs are the outbound logistics costs of carrying the product to the client’s destination.

During 2009, cost of sales decreased by 7.7% as a result of lower sawn timber sales volume as well as lower unit costs of wood, chemicals and energy, reflecting Arauco’s stringent cost management and favorable market conditions for raw materials.

Cost of sales increased 5.8% during 2010, mainly due to higher cost of sales of our forestry operations and an increase in other raw materials and indirect costs, partially offset by lower maintenance costs.

During 2011, cost of sales increased 26.6% as a result of increased sales volumes among all of our business segments and increases in the unitary costs of our main products. In particular, our costs of sale per ton of our bleached softwood pulp, bleached hardwood pulp and unbleached softwood pulp increased 10.7%, 21.7% and 15.5%, respectively, as compared to 2010. In 2011, our cost of sales measured as a percentage of total revenues represented 65.9%, as compared to 60.4% in 2010.

Cost of sales increased 9.2% during 2012 as a result of increased sales volume in all of our business segments and increases in the unitary costs of our main products. Compared to 2011, our costs of sales per ton increased 8.7% for bleached softwood pulp, increased 7.2% for bleached hardwood pulp, and increased 19.1% for unbleached softwood pulp. In 2012, our cost of sales measured as a percentage of total revenues was 73.6%, as compared to 65.9% in 2011.

Critical Accounting Policies

A summary of our significant accounting policies is included in Note 1 to our audited consolidated financial statements, which are included in this annual report. The preparation of consolidated financial statements in accordance with IFRS requires management to make subjective estimates and assumptions that affect the amounts reported. Estimates are based on historical experience and various other assumptions that are believed to be reasonable, though actual results and timing could differ from the estimates. Management believes that the accounting policies below take into account those matters that require the exercise of judgment, but acknowledge that different judgments could result in substantially different results. The most critical accounting policies and estimates are described below.

Property, Plant and Equipment

Property, plant and equipment are stated at cost and are depreciated using the straight-line method based on the estimated useful lives of the assets. The amount of such depreciation that related to our fixed production assets, such as pulp mills and sawmills, is allocated to finished goods held as inventories and accumulates until charged to cost of sales when the finished goods are sold. Forests and lands are not depreciated.

55

In estimating the useful lives we have primarily relied upon actual experience with the same or similar types of equipment and recommendations from the manufacturers. Useful lives are based on the estimated amount of years an asset will be productive and are revised periodically to recognize potential impacts caused by new technologies, changes to maintenance procedures, changes in utilization of the equipment, and changing market prices of new and used equipment of the same or similar types.

Property, plant and equipment assets are evaluated for possible impairment. Factors that would indicate potential impairment may include, but are not limited to, significant decreases in the market value of a long-lived asset, a significant change in a long-lived asset’s physical condition and operating or cash flow losses associated with the use of a long-lived asset. This process requires our estimate of future cash flows generated by each asset or group of assets. For any instance where this evaluation process indicates impairment, the appropriate asset’s carrying values are written down to net realizable value and the amount of the write-down is charged against the results of continuing operations.

Expenditures that substantially improve and/or increase the useful life of facilities and equipment are capitalized. Other maintenance or repair costs are charged to income as they are incurred.

Fair Value of Financial Instruments

The Company recognizes certain financial assets and liabilities on its statement of financial position at fair value, which is the value that the Company estimates would be attributable to such asset or liability in an arms-length transaction. As of the date of the initial recognition, the management of the Company classifies its financial assets at fair value through (i) income or (ii) collectible credits and accounts, depending on the purpose for which the financial assets were acquired.

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. Arauco uses its judgment to select a variety of methods and make assumptions that are mainly based on market conditions existing at each balance sheet date.

The doubtful provision of trade receivables is established when there is evidence that Arauco will not receive payments under the original terms of sale. Provisions are made when the client is a party to a bankruptcy court agreement or cessation of payments, or when Arauco has exhausted all levels of recovery of debt in a reasonable time. See Note 23 to our consolidated financial statements.

Biological Assets

IAS 41 requires that biological assets, such as standing trees, are shown on the statement of financial position at fair value. Our forests are thus accounted for at fair value less estimated point-of sale costs at harvest, considering that the fair value of these assets can be measured reliably.

The recovery of forest plantations is based on discounted cash flow models, which means that the fair value of biological assets is calculated using cash flows from continuing operations on the basis of sustainable forest management plans and considering the potential growth of forests. This recovery is performed on the basis of each forest stand identified and for each type of tree species.

These discounted cash flows require estimates in growth, harvest, sales prices and costs. It is therefore important that management make appropriate estimates of future levels and trends for sales and costs, as well as administers regular surveys of the forests to establish the volumes of wood available for harvesting and their current growth rates. The principal considerations used to calculate the valuation of forest plantations are presented in Note 20 to our audited consolidated financial statements.

56

Lawsuits and Contingencies

Arauco and its subsidiaries are subject to certain ongoing lawsuits, the future effects of which need to be estimated by the management of the Company in collaboration with its legal advisors. Arauco evaluates the reports of its legal advisors and make appropriate contingency estimates in each statement of financial position based on such reports. Arauco also makes contingency estimates and/or adjustments to prior contingency estimates upon the occurrence of material changes to the nature or underlying facts of such lawsuits. See “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry—We are subject to legal proceedings related to our mills which could adversely affect our business, financial condition, results of operations and cash flows.” and “Item 8. Financial Information—Legal Proceedings.”

Year Ended December 31, 2011 Compared to Year Ended December 31, 2012

Revenue

Revenue decreased 2.2% from U.S.$4,374 million in 2011 to U.S.$4,280 million in 2012, primarily as a result of:

• a 9.9% decrease in revenue from pulp; and

• a 4.8% decrease in revenue from forestry products; partially offset by

• a 4.7% increase in revenue from wood products; and

• a 3.7% increase in revenue from panels.

Pulp

Revenue from bleached and unbleached pulp decreased 9.9% from U.S.$2,060.8 million in 2011 to U.S.$1,856.5 million in 2012, reflecting a 14.6% decrease in average prices, partially offset by a 5.5% increase in sales volume. Sales of bleached pulp decreased 10.8% due to a 14.9% decrease in average prices, partially offset by a 4.9% increase in sales volume. Revenue from unbleached pulp decreased 4.9% due to a 13.1% decrease in average prices, partially offset by a 9.5% increase in sales volume.

Panels

Revenue from panels increased 3.7% from U.S.$1,273.7 million in 2011 to U.S.$1,320.5 million in 2012. This increase in revenues was primarily due to a 10.4% increase in sales volume, partially offset by a 6.1% decrease in average prices. During 2012, we experienced an increase in sales volume due to the acquisition of the Moncure mill and Flakeboard.

Wood products

Revenue from sawn timber and remanufactured wood products increased 4.7% from U.S.$731.6 million in 2011 to U.S.$766.2 million in 2012, primarily as a result of a 6.1% increase in average prices, partially offset by a 1.2% decrease in sales volume. Sawn timber sales revenue increased 2.7% from U.S.$526.8 million to U.S.$541.2 million due to a 6.7% increase in average prices, partially offset by a a 3.7% decrease in sales volume. Remanufactured products sales revenue increased 13.2% from U.S.$198.3 million to U.S.$224.5 million due to a 13.6% increase in sales volume, partially offset by a 0.3% decrease in average prices. The North American markets in particular experienced a strong demand for value-added wood products.

Forestry products

Revenue from forestry products decreased 4.8% from U.S.$157.5 million in 2011 to U.S.$149.9 million in 2012. This decrease was primarily the result of a 30.0% decrease in the sales revenue of pulplogs, partially offset by a 14.5% increase in the sales revenue of sawlogs.

Other revenue

Revenue from other sources, consisting principally of sales of energy and chemicals, increased 24.1% from U.S.$150.9 million in 2011 to U.S.$187.2 million in 2012. This was primarily the result of a U.S.$38.5 million increase in our energy sales.

59

Cost of sales

Cost of sales increased 9.2% from U.S.$2,882.5 million in 2011 to U.S.$3,148.5 million in 2012, primarily as a result of an increase in the sales volumes of our pulp and panels business segments and an increase in unitary costs of our forestry and wood products. In particular, as compared to 2011 the cost of timber increased by 12.5%, or U.S.$79.8 million, our indirect costs increased by 69.8% or US.$67.2 million and our chemical costs increased by 13.9% or U.S.$46.6 million. We have also experienced an increase in costs in our pulp business. In particular, our cost of sales per ton of BKPR and EKPR increased 9.3% and 7.2%, respectively, and our cost of sales per ton of UKPR increased 19.1%, as compared to 2011.

Gross profit

Our gross profit decreased from 34.1% for 2011 to 26.4% for 2012, primarily as a result of a 9.2% increase in cost of sales, and a 2.2% decrease in sales revenue.

Other income

Other income decreased 17.8% from U.S.$475.0 million in 2011 to U.S.$390.5 million in 2012, mainly as a result of lower net proceeds from insurance payments. In 2011 we recorded a gain of U.S.$194.0 million due to the insurance payments related to the February 2010 earthquake. In 2012 we recorded a gain of U.S.$89.0 million in insurance payments mainly related to the Nueva Aldea fire in January 2012 and the turbo generator stoppage in the Valdivia mill. The decrease in other income was partially offset by a net increase of U.S.$20.1 million in gains of non-core real estate assets in 2012.

Distribution costs

Distribution costs decreased 5.4% from U.S.$477.6 million in 2011 to U.S.$451.8 million in 2012, primarily due to a 3.6% or U.S.$15.7 million decrease in shipping and freight total costs and partially offset by a 5.5% increase in volume sales of pulp and a 10.4% increase in volume sales of panels. As a percentage of revenue, distribution costs decreased from 10.9% to 10.6% in 2012.

Administrative expenses

Administrative expenses increased 14.1% from U.S.$415.5 million in 2011 to U.S.$474.0 million in 2012, primarily as a result of an increase in wages and salaries, insurance and other administrative expenses of U.S.$34.1 million, U.S.$13.9 million and U.S.$25.4 million respectively. This increase is mainly attributable to an increase in our rate of hiring. As a percentage of revenue, administrative expenses increased from 9.5% in 2011 to 11.1% in 2012.

Finance costs

Finance costs increased 19.0% from U.S.$196.4 million in 2011 to U.S.$233.7 million in 2012. This increase was mainly due to prepayment accounting charges of U.S.$22.1 million incurred by Flakeboard and an increase of interest expenses of U.S.$9.9 million related to our other financial instruments, mainly forwards and swaps.

Exchange rate differences

We recorded a 29.2% decrease in exchange rate difference losses from U.S.$26.6 million in 2011 to U.S.$18.9 million in 2012, primarily as a result of foreign exchange losses attributable to money market investments, deposits and accounts receivables denominated in currencies which appreciated against the U.S. dollar, partially offset by payables liabilities denominated in currencies that appreciated against the U.S. dollar, including the Chilean peso, real and euro, among others.

60

Income tax

We recorded an income tax expense of U.S.$152.5 million in 2011 compared to U.S.$171.2 million in 2012. This increase is mainly explained by an extraordinary charge of approximately U.S.$129.0 million explained by a net increase in deferred tax liabilities as a consequence of Law No. 20,630, which was published on September 27, 2012. Among various changes to the Chilean tax code, the application of this law increased the corporate tax rate for Chilean corporations to 20% from 18.5%, effective for taxes payable during fiscal year 2013, including income earned during 2012. In addition, we had a lower deferred tax income relating to origination and reversal of temporary differences of U.S.$0.7 million in 2012 compared to U.S.$45.6 million in 2011. This decrease was partially offset by a lower current income tax expense of U.S.$65.6 million in 2012 compared to U.S.$242.9 million in 2011.

Net income

Net income in 2012 decreased 77.4% from U.S.$620.8 million in 2011 to U.S.$140.5 million in 2012, primarily as a result of a 2.2% decrease in our revenue, a 9.2% increase in our cost of sales, a 14.1% increase in our administrative expenses and distribution costs, as discussed above, an extraordinary charge in income tax expenses of U.S.$129.0 million and a decrease in net proceeds from insurance payments from U.S.$194.0 million in 2011 to U.S.$89.0 million in 2012, as discussed above.

Year Ended December 31, 2010 Compared to Year Ended December 31, 2011

Revenue

Revenue increased 16.1% from U.S.$3,767.4 million in 2010 to U.S.$4,374.5 million in 2011, primarily as a result of:

• a 15.6% increase in revenue from panels;

• a 16.0% increase in revenue from pulp;

• a 18.0% increase in revenue from wood products; and

• a 4.9% increase in revenue from forestry products.

Pulp

Revenue from bleached and unbleached pulp increased 16.0% from U.S.$1,777.1 million in 2010 to U.S.$2,060.8 million in 2011, reflecting a 18.4% increase in sales volume, partially offset by a 2.1% decrease in average prices. Sales of bleached pulp increased 15.0% due to a 18.8% increase in sales volume, partially offset by a 3.2% decrease in average prices. Revenue from unbleached pulp increased 21.9% due to a 16.13% increase in sales volume and a 5.0% increase in average prices.

When comparing to 2010, the increase in revenues in 2011 was primarily driven by increased sales volume as a result of the interruption of operations at our Chilean pulp mills in March, April and May, 2010 as a result of the earthquake that hit the South-Central Region of Chile on February 27, 2010.

Panels

Revenue from panels increased 15.6% from U.S.$1,101.6 million in 2010 to U.S.$1,273.7 million in 2011. This increase in revenues was primarily due to an 8.8% increase in average prices and a 6.3% increase in sales volume.

Our plywood sales volume increased in 2011 primarily because our plants were running at full capacity as compared to 2010, during which we experienced the interruption of our operations in Chile as a result of the earthquake of February 27, 2010. In addition, we experienced an increase in sales volume in Europe and Asia, primarily as a result of increased demand in those markets, which increase contributed to substantial price recoveries.

61

On the other hand, the U.S. market also experienced a strong increase in sales volume; however, price levels remained stable. In 2011, our average prices increased primarily as a result of higher demand for our products during 2011 compared to 2010, when prices for plywood, medium-density fiberboard, particleboard and hardboard deteriorated due to a decrease in global demand for these products.

Wood products

Revenue from sawn timber and remanufactured wood products increased 18.0% from U.S.$620.1 million in 2010 to U.S.$731.6 million in 2011, primarily as a result of a 11.9% increase in average prices and a 5.4% increase in sales volume. Sawn timber sales revenue increased 13.6% from U.S.$463.8 million to U.S.$526.8 million due to a 9.3% increase in average prices and a 3.9% increase in sales volume. Remanufactured products sales revenue increased 32.5% from U.S.$149.7 million to U.S.$198.3 million due to a 15.1% increase in average prices and a 14.9% increase in sales volume. During 2011, we continued to experience strong demand for our wood products in most markets, especially in Asia. Consequently, sales prices increased in China, Korea, Japan and Taiwan.

Forestry products

Revenue from forestry products increased 4.9% from U.S.$150.2 million in 2010 to U.S.$157.5 million in 2011. This increase was primarily the result of an 82.7% increase in the sales revenue of pulplogs, mainly due to higher sales volume, when compared with 2010.

Demand for our forestry products increased in 2011 as a result of the recovery from the global financial crisis and an increase in worldwide construction, which triggered a significant increase in demand for pulplogs, sawlogs, chips and posts.

Other revenue

Revenue from other sources, consisting principally of sales of energy and chemicals, increased 27.4% from U.S.$118.4 million in 2010 to U.S.$150.9 million in 2011. This increase is explained by higher sales of energy of U.S.$12.2 million and an increase in sales of chemicals by U.S.$13.3 million.

Cost of sales

Cost of sales increased 26.6% from U.S.$2,276.4 million in 2010 to U.S.$2,882.5 million in 2011, primarily as a result of an increase in the sales volumes of each of our business segments and increased unitary costs of our main products. In particular, our costs of sale per ton of BKPR, EKPR and UKPR have increased 10.7%, 21.7% and 15.5%, respectively, as compared to 2010. These increases have been driven primarily by increases in the cost of wood (which increased by 15.3% during 2011 as compared to 2010) and chemicals (which increased by 38.9% during 2011 as compared to 2010) and a 10.9% increase in the average Chilean peso/U.S. dollar exchange rate from Ch$468.01 per U.S.$1.00 during 2010 to Ch$519.20 per U.S.$1,00 in 2011.

Gross profit

Our gross profit decreased from 39.6% for 2010 to 34.1% for 2011 primarily as a result of a 26.6% increase in cost of sales, partially offset by a 16.1% increase in sales revenue.

Other income

Other income increased 25.5% from U.S.$378.5 million in 2010 to U.S.$475.0 million in 2011, mainly as a result of a net gain of U.S.$192.9 million attributable to the business interruption insurance claims related to the February 27, 2010 earthquake net of asset write-offs and operational expenses of stopped mill and a U.S.$8.4 million increase in the fair value of our biological assets, which was primarily the result of increases in the market prices of our products.

62

Distribution costs

Distribution costs for all markets increased 25.1% from U.S.$381.9 million in 2010 to U.S.$477.6 million in 2011, primarily as a result of an increase in shipping and freight total costs. The increase in shipping and freight costs was mainly explained by an 18.4% increase in the sales volume of pulp, a 6.3% increase in the sales volume of panels and a 5.4% increase in the sales volume sawn timber.

Administrative expenses

Administrative expenses increased 28.3% from U.S.$323.9 million in 2010 to U.S.$415.5 million in 2011, primarily as a result of an increase in wages and salaries, insurance and other administrative expenses of U.S.$14.3 million, U.S.$10.9 million and U.S.$26.4 million respectively. As a percentage of revenue, administrative expenses increased from 8.6% in 2010 to 9.5% in 2011.

Finance costs

Finance costs decreased 5.4% from U.S.$207.5 million in 2010 to U.S.$196.4 million in 2011. This decrease is explained primarily by a decrease in the average interest rate applicable to our long-term debt.

Exchange rate differences

We recorded an increase in exchange rate difference losses of 63.6% from U.S.$16.3 million in 2010 U.S.$26.6 million in 2011, primarily as a result of foreign exchange losses attributable to money market investments, deposits and accounts receivables denominated in currencies which depreciated against the U.S. dollar, partially offset by foreign exchange gains attributable to our financial debt denominated in currencies that depreciated against the U.S. dollar, including the Chilean peso, real and euro, among others.

Income tax

We recorded an income tax expense of U.S.$198.0 million in 2010 compared to tax expenses of U.S.$152.5 million in 2011. This decrease was principally attributable to lower income before taxes in 2011 compared to 2010. Our effective tax rate decreased from 22.0% in 2010 to 19.7% in 2011, mainly due to an increase in the proportion of profits earned by our Chilean subsidiaries, which have a lower tax rate than each of our foreign subsidiaries.

Net income

Net income in 2011 decreased 11.4% from U.S.$700.7 million in 2010 to U.S.$620.8 million in 2011, primarily as a result of the increases in our cost of sales, administrative expenses and distribution costs as discussed above.

Liquidity and Capital Resources

Our primary sources of liquidity are funds from operations, domestic and international borrowings from commercial and investment banks and debt offerings in the domestic and international capital markets.

Arauco has a liquidity policy, approved by the board of directors, that maintains conservative criteria regarding Arauco’s liquidity management. Using a combination of different variables, we define scenarios, each of which has independent criteria for defining a minimum liquidity level.

We also have access to two committed credit facility lines amounting to an aggregate of approximately U.S.$320 million. The first line has an available amount of UF 1,700,000, or approximately U.S.$ 80.9 million. The second line has a maximum available amount of U.S.$ 240.0 million.

63

Cash Flow from Operating Activities

Our net cash flow provided by operating activities was U.S.$458.5 million in 2012 and U.S.$982.2 million in 2011. This decrease was principally due to a U.S.$329.7 million increase in payments for goods and services, a decrease of U.S.$137.7 million in receipts from premiums and claims, annuities and other policy benefits and a U.S.$91.7 million increase in payments to and on behalf of employees, partially offset by an increase of U.S.$98.2 million in receipts from sales of goods and rendering of services.

Our net cash flow provided by operating activities was U.S.$982.2 million in 2011 and U.S.$1,137.3 million in 2010. The decrease of net cash provided by operating activities in 2011 as compared to 2010 was principally due to a U.S.$656.5 million increase in payments for goods and services and a U.S.$149.6 million increase in income tax paid, partially offset by an increase of U.S.$622.4 million in our collection of sales revenue. The increase in both payments for goods and services and collection of sales revenue is mainly explained by higher sales volume during year 2011 as a consequence of the earthquake of February 27, 2010 that interrupted most of our operations in Chile during that year.

Cash Flow Used in Investing Activities

Our net cash used in investing activities was U.S.$1,027.0 million in 2012 and U.S.$1,208.9 million in 2011. This decrease was principally due to a 94.4% or U.S.$228.8 million decrease in capital contributions to non-controlling entities (primarily due to our 2011 acquisition of Florestal Vale do Corisco Ltda.) and a 69.7% or U.S.$139.2 million decrease in loans to related companies (primarily Montes del Plata), partially offset by an increase in capital contributions to subsidiaries or other business in the amount of U.S.$190.9 million mainly due to the Moncure mill and Flakeboard acquisitions.

Our net cash used in investing activities was U.S.$1,208.9 million in 2011 and U.S.$669.4 million in 2010. This increase was principally due to capital contributions in the amount of U.S.$242.4 million that we made to the Montes del Plata joint venture and the acquisition of Florestal Vale do Corisco Ltda. by Centaurus Holdings S.A. (a Brazilian company in which we own 49% of the capital stock), for which we paid U.S.$232 million of the purchase price.

Cash Flow from Financing Activities

Our net cash obtained from financing activities was U.S.$648.1 million in 2012 compared to the U.S.$481.2 million used in 2011. This variation is mainly due to a U.S.$1,122.8 million increase in proceeds from loans, primarily related to our 2012 issuance of U.S.$942.8 million in long term financing. In addition, in 2012 we experienced a U.S.$94.7 million decrease in the payment of dividends.

Our net cash used in financing activities was U.S.$481.2 million in 2011 compared to U.S.$33.9 million obtained from financing activities in 2010. This variation is mainly due to a U.S.$267.2 million increase in payments of principal and interest on our debt and a U.S.$132.7 million increase in the payment of dividends.

We believe that cash flow generated by operations, cash balances, borrowings from commercial banks and debt offerings in the domestic and international capital markets will be sufficient to meet our working capital, debt service and capital expenditure requirements for the foreseeable future. See “Item 4—Information on the Company—Capital Expenditures.”

64

Contractual Obligations

In accordance with customary practice in the pulp industry, we generally do not have long-term sales contracts with our customers; rather, we maintain relationships with our customers, with whom we reach agreements from time to time on specific volumes and prices.

The following table sets forth certain contractual obligations as of December 31, 2012, and the period in which the contractual obligations come due.

			Payments Due by Period
	Less than 1 year		1-3 years		3-5 years		More than 5 years		Total

(1) Includes estimated interest payments related to long-term debt obligations based on market values as of December 31, 2012.

(2) Forestal Río Grande S.A. is a special purpose entity, which we control but do not own. As a result, we include the financial information of Forestal Río Grande S.A. in our financial statements, including its long term debt obligations.

(3) Excludes contracts entered into with independent contractors to perform operations on our behalf. Our payment obligations under such contracts are not pre-determined, but rather depend on the performance of certain variables. Accordingly, we cannot quantify our contractual obligations under such contracts.

Investment Activities

During 2012, our principal investment activities were as follows:

• On December 29, 2011, we entered into an asset purchase agreement to acquire a panel industrial facility in Moncure, North Carolina. This transaction closed in January 2012 for U.S.$62.7 million.

• On June 7, 2012, we entered into a share purchase agreement to acquire 100% of the shares of Flakeboard Company Limited, a Canadian company that operates seven panel production facilities in Canada and the United States. This transaction closed in September 2012 for a total purchase price of U.S.$242.5 million.

65

Financing Activities

During 2012, our principal financing activities were as follows:

• On January 11, 2012, we issued U.S.$500 million aggregate principal amount of 4.75% bonds due in 2022 in the international capital markets. On June 13, 2012, we initiated an offer to exchange those outstanding bonds for an equal principal amount of 4.75% SEC-registered notes. The exchange notes had terms substantially identical to the outstanding notes, except with respect to transfer restrictions, registration rights and certain rights to additional interest that were applicable only to the unregistered bonds.

• On April 26, 2012 we issued UF5 million aggregate principal amount of bonds in the Chilean market, which was the equivalent of approximately U.S.$238 million. The bonds were issued with a yield of 3.88%, with a maturity of 21 years and a grace period of 10 years.

• In October 2012, we entered into a three-year revolving committed liquidity facility with Corpbanca S.A. that has a maximum available amount of UF 1,700,000, or approximately U.S.$80.9 million. As of April 2013, this line has not been used.

• On November 1, 2012, Flakeboard Company Limited, one of our U.S. subsidiaries, entered into a U.S.$150 million unsecured loan agreement with Export Development Canada, J.P. Morgan Securities LLC and Mizuho Corporate Bank, LTD. The loan is guaranteed by Arauco and has a five-year term with a three-year grace period.

• In November 2012, we entered into a three-year revolving committed facility with J.P. Morgan Securities LLC, Banco Estado de Chile, New York Branch, Deutsche Bank Securities Inc. and HSBC Securities Inc. USA that has a maximum available amount of U.S.$240 million. As of April 2013, this line has not been used.

As of December 31, 2012, our short-term bank debt was U.S.$413.3 million of which 88.1% was U.S. dollar-denominated. As of December 31, 2012, our total long-term bank debt (including the current portion of such debt) was U.S.$508.4 million of which 92.7% was U.S. dollar-denominated. In addition, as of December 31, 2012, we guarantee obligations of U.S.$555.9 million related to Montes del Plata, U.S.$270.0 million related to Alto Paraná and U.S.$150 million related to Flakeboard. As of December 31, 2012, we also had total capital markets borrowings (including the current portion of such debt) of U.S.$3,417.8 million, 72.8% of which was U.S. dollar-denominated. As of December 31, 2012, the weighted average maturity of our long-term debt was 6.3 years. The interest rate on our variable rate debt is determined principally by reference to the London inter-bank offered rate (LIBOR), and as of December 31, 2012, the average interest rate for our U.S. dollar floating rate debt over nine-month LIBOR was 1.45%. As of December 31, 2012, the average interest rate for our U.S. dollar fixed rate debt was 5.21%. These average rates do not reflect the effect of swap agreements and subsequent unwinds effective as of December 31, 2012.

The instruments and agreements governing our bank loans and local bonds set limits on our incurrence of debt and liabilities through the use of financial covenants. The principal financial covenants contained in the bank loan agreements are as follows:

• Our debt to equity ratio must not exceed 1.2:1; and

• Our interest coverage ratio must not be less than 2:1.

The principal financial covenant contained in the local bond agreements is:

• Our debt to equity ratio must not exceed 1.2:1.

We were in compliance with all bank loans and bonds covenants as of December 31, 2012.

66

OFF-BALANCE SHEET ARRANGEMENTS

In addition to the debt that is reflected on our balance sheet, we guarantee 50% of the following debt of Celulosa y Energía Punta Pereira and Zona Franca Punta Pereira, each a Uruguayan affiliate of our Montes del Plata joint venture:

• the IDB Facility Agreement, which has a maximum available amount of U.S.$454,000,000; and

• the Finnvera Guaranteed Facility Agreement which has a maximum available amount of up to U.S.$900,000,000.

For more information, see “Item 3. Key Information—Risk Factors—Risks Relating to Uruguay—Economic conditions in Uruguay may have a direct impact on our financial condition, results of operations and cash flows” and Note 23 to our audited consolidated financial statements.

As of December 31, 2012, U.S.$1,111.9 million of an aggregate maximum available amount of U.S.$ 1,354.0 million was outstanding under both facilities, of which outstanding amount we guarantee 50%. The guarantees were issued to enhance the credit worthiness of the borrowing entities in order to allow such entities to obtain, under more favorable conditions, the financing necessary for the construction of a pulp mill and port terminal in Punta Pereira, Uruguay, which we expect to positively contribute to the financial condition and results of operations of our Montes del Plata joint venture. For more information regarding the status of the construction of the mill, see “Item 4. Information on the Company—Pulp—Pulp mills—Uruguay”. If Celulosa y Energía Punta Pereira or Zona Franca Punta Pereira default under any or both of these facilities, we may be required to make a payment on their behalf or to assume on our balance sheet the portion of their debt that we guarantee, an outcome that could materially adversely affect our financial expenses, net income, ability to raise additional debt and credit ratings.

TREASURY MANAGEMENT

We manage the treasury activities of all of our Chilean subsidiaries on a centralized basis. Our Chilean subsidiaries borrow from or lend money to us in accordance with their daily cash requirements or surplus, maintaining their cash balance close to zero. Our policy is not to allow our Chilean subsidiaries to invest in financial instruments and other transactions. We make decisions regarding short-term loans, short-term investments, currency transactions and other transactions on a consolidated basis. Treasury activities are governed by our cash and deposits policy, which is approved by the board of directors. The main principles of our cash and deposits policy are as follows:

• investments must be in fixed income instruments;

• we do not invest in stocks;

• investments must be in instruments from the Central Bank of Chile or from reputable financial institutions; and

• transactions must be carried out only with banks or bank subsidiaries.

Our Argentine, Brazilian, Canadian and U.S. subsidiaries manage their treasury activities independently from us. Their activities are governed by cash and deposit policies that are approved by our Chief Financial Officer. These policies are based on the same principles underlying our cash and deposits policy.

HEDGING

We periodically review our exposure to risks arising from fluctuations in foreign exchange rates and interest rates and make a determination, on a case-by-case basis, at our senior management level whether or not to hedge such risks. As a result, from time to time we enter into currency and interest rate swaps with respect to a portion of our borrowings. See Note 23 to our audited consolidated financial statements.

Interest Rate Swap Agreements

The Bío Bío Investment Fund, with which we entered into certain agreements pursuant to which we became the administrator and exclusive buyer of the forestry assets acquired from Forestal Bío Bío S.A., entered into an interest rate swap agreement, in an initial notional amount of U.S.$240 million with amortizations during the life of the swap in the same amount and dates of the amortizations of the credit agreement the Bío Bío Investment Fund obtained on October 6, 2006, with interest rate settled quarterly and with a final maturity in October 2013. The net effect of this interest rate swap agreement is that the Bío Bío Investment Fund pays fixed interest rate at a rate of 5.256% and receives a floating rate at 3 months LIBOR. In January 2007, the Bío Bío Investment Fund transferred all of its assets and financial debt to Forestal Río Grande S.A.

The aggregate fair value of our currency swap agreements as of December 31, 2012 represented an asset of U.S.$47.6 million and as of December 31, 2011 represented a liability of U.S.$0.2 million.

These cross currency swap agreements allow us to address uncertainties regarding exchange rates. Through these agreements, we receive cash flows in UF, which allow us to comply with the terms of our outstanding bonds and pay fixed amounts in dollars, the currency in which a significant amount of our assets are denominated.

We have also analyzed our exposure to risks associated with fluctuations in the prices of commodities, including pulp, but have, thus far, not entered into any material hedging transactions with respect to such risks.

RESEARCH AND DEVELOPMENT

We spent U.S.$2.2 million in 2012, U.S.$3.5 million in 2011 and U.S.$3.1 million in 2010 on research and development. We conduct our principal research and development programs through our subsidiary, Investigaciones Forestales Bioforest S.A., which concentrates its efforts on applying and implementing advanced technologies to the specific characteristics of our forests and mills.

We are continuously researching and attempting to develop different strains of long-fiber pine trees to improve their quality and to shorten their average harvest cycle. Additionally, we maintain close relations with certain international research institutes, equipment suppliers and the scientific and engineering communities that participate in our industry.

TREND INFORMATION

World pulp prices for hardwood and softwood increased during the first quarter of 2013. As of March 31, 2013, the northern bleached softwood kraft pulp index has increased 3.8% as compared to December 31, 2012, reaching U.S.$840.75 per tonne, and the bleached hardwood kraft pulp index has increased 3.6% as compared to December 31, 2012, reaching U.S.$803.50 per tonne. New hardwood pulp capacity has entered the market, but this influx of supply has had little impact on price. The main driver of the first quarter price increase was strong demand from Asia, particularly from China.

The European pulp market has not yet recovered from 2012’s depressed market. Unstable financial markets have translated into a lack of paper demand; and lower paper productions levels have reduced demand for pulp. Furthermore, certain European integrated paper producers have cut paper production while continuing to produce pulp, mainly long-fiber pine pulp (the most commonly used pulp grade in Europe), which has increased pulp supply in European and Asian markets and crowded out foreign producers.

The real estate and construction sectors in the United States have shown significant improvement during the fourth quarter of 2012 and the opening months of 2013. The housing starts index reached 917,000 units in February 2013, a 39.6% increase as compared to the 657,000 unit per year reached in December 2011. During the first few months of 2013, we have experienced strong demand and price increases for MDF and MDF moldings in the North American market. In Latin America, we have experienced increasing demand and prices for our panel products, and we expect demand and prices to continue to rise for the remainder of 2013.

Under Chilean and Brazilian labor legislation, we are secondarily liable for the payment of labor and the social security obligations owed to employees of our contractors. In Chile, in the event that we do not exercise the rights granted to us by the labor laws regarding the supervision of our contractors in their compliance of their labor and social security obligations, then our responsibility is elevated from secondary to joint and several, thus enabling an employee of a contractor to bring a claim relating to these obligations against both the contractor and to us, as the party hiring such contractor, although the contractor would remain primarily liable for such obligations. Furthermore, as a general rule, we are also responsible for some of the health and safety conditions of the contractors’ workers, and we are obligated to supervise the compliance by our contractors with all obligations related to such conditions while such workers are performing activities for us within our corporate purpose.

In Argentina, substantially similar joint liability rules apply to a principal and its contractors. In addition, a new national rural labor law, Law 26,727, promulgated on December 28, 2011 but which became fully operational in March 2013 after publication of certain relevant regulations, permits contractor employees under forestry contracts to bring actions directly against the principal to whom the employees’ services are being provided, instead of requiring them to bring actions against the contractor. For work or services related to the ordinary production process of a principal, the law provides that an employment relationship exists between the principal and the employee of the contractor.

19.3% of our employees in Chile, 46.9% of our employees in Argentina, 10.7% of our employees in Brazil and none of our employees in the United States or Canada were unionized as of December 31, 2012. We negotiate collective bargaining agreements of two, three or four years’ duration with unionized employees.

We have stable employee relations in Chile, Argentina, Brazil, the United States and Canada. Our Chilean operations have not experienced any work stoppages in the last five years other than (i) a four-day work stoppage in July 2012 at our Horcones Panel Mill located in Arauco, during which production resumed partially after the second day, (ii) a ten-day work stoppage in November 2009 at our Constitución pulp mill, our Trupán-Cholguán panel mill,

75

and our Nueva Aldea and Horcones complexes, (iii) a three-day work stoppage in September 2009 at our Constitución and Valdivia pulp mills, our Trupán-Cholguán panel mill, and our Nueva Aldea and Horcones complexes; and (iv) a six-day work stoppage in May 2007 at our Horcones complex (which includes the Arauco pulp mill, a panel plant and two sawmills), each of which was caused by the employees of our third party forestry contractors at each of the respective facilities.

Our Argentinean operations have not experienced any work stoppages in 2012. However, we experienced (i) a 3-day stoppage at Alto Paraná’s chemical mill in March 2011, as a result of a strike by the chemical union and (ii) a 4-day stoppage at Alto Paraná’s pulp mill in September 2010, as a result of a strike by the pulp union, but these strikes were limited to two hours per shift and did not materially affect operations. In January 2008, Alto Paraná’s chemical mill in Argentina experienced a three-day work stoppage, but these strikes were limited to two hours per shift and did not materially affect operations. In addition, in January and February 2007, we experienced (i) a 12-day stoppage at our Zárate mill due to a dispute arising between the local chemical and timber unions with regard to the representation of their workers at the mill and (ii) a six-day suspension of operations at the Alto Paraná’s pulp mill as a result of a strike by a group of approximately 150 power saw operators.

For information regarding strikes and work stoppages occurred in the last five years at our Argentinean subsidiary, see “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry—Our operations could be adversely affected by labor disputes.”

Our Brazilian operations have not experienced any work stoppages in the last five years.

In September 2011, we experienced a 12-day work stoppage of construction at our Montes del Plata joint venture in Uruguay.

During the last year, there have been no strikes or other material work stoppages at our U.S. and Canadian subsidiaries.

Item 7. Major Shareholders and Related Party Transactions

MAJOR SHAREHOLDERS

Our only outstanding voting securities are shares of common stock of a single series, without nominal (par) value. The following table sets forth certain information concerning ownership of our common stock, as of April 30, 2013, with respect to each shareholder known by us to own more than 5% of the outstanding shares of our common stock and all of our directors and executive officers, as a group.

	Number of Shares Owned		Percentage Ownership
Empresas Copec		113,127,605		99.98
Directors and executive officers of the Company, as a group		—		—

Through its ownership of our Common Stock, Empresas Copec currently has voting control over us.

Empresas Copec is a Chilean public company listed on the Santiago Stock Exchange, the Valparaíso Stock Exchange and the Chilean Electronic Stock Exchange. It is a holding company, the principal interests of which are in Arauco, gasoline distribution, electricity, gas distribution and fishing. Before October 1, 2003, Empresas Copec’s legal name was Compañía de Petróleos de Chile S.A. As of that date, Compañía de Petróleos de Chile S.A. transferred all its gasoline- and fuel-related business assets to a new subsidiary, Compañía de Petróleos de Chile COPEC S.A., which we call COPEC, and changed its legal name to Empresas Copec S.A. In May 2005, AntarChile purchased 3.1 million shares of COPEC, increasing its ownership to 60.4% of Empresas Copec. As of December 31, 2011, AntarChile owned 60.8% of Empresas Copec.

Through its ownership in Empresas Copec, AntarChile beneficially owned 60.8% of our shares as of December 31, 2012. As of April 30, 2013, AntarChile beneficially owns 60.8% of our shares. Inversiones Angelini y Compañía Limitada (“Inversiones Angelini”) in turn owns 63.4% of AntarChile’s shares, and certain other related investors own an additional 10.96% of AntarChile. Inversiones Angelini and such other investors are defined herein as the “Angelini Group.”

The principal equity owners of interest in Inversiones Angelini are Mrs. María Noseda Zambra with 10.9%, Mr. Roberto Angelini Rossi directly and indirectly with 22.4%, and Mrs. Patricia Angelini Rossi directly and indirectly with 18.8%.

As of December 31, 2012 and April 30, 2013, the Angelini Group controlled Arauco through the ownership structure described above.

RELATED PARTY TRANSACTIONS

We engage in a variety of transactions in the ordinary course of business with related parties. Related parties include, among others, directors, officers and affiliates of the Company. The new Title XVI, or “Title XVI”, of the Chilean Companies Act, which was included by Law Nº 20,382 published in the Official Gazette on October 20, 2009, amended among others, articles 44 and 89 of the Chilean Companies Act, establishing the applicable norms for transactions with related parties by and among public corporations and their subsidiaries. Title XVI requires that our transactions with related parties contribute to the company’s interest and be on a market basis or on terms similar to those prevailing in the market. In addition, Title XVI provides that related party transactions must be approved by an informed majority of the disinterested members of the board of directors. If a majority of the disinterested directors abstains from voting on a particular transaction, the transaction must be approved by a unanimous vote of the non-abstaining disinterested directors or by a two-thirds of the shares with voting rights. Resolutions approving any such transactions must be reported to our shareholders at the next annual shareholders’ meeting.

77

Notwithstanding the above, in accordance with Article 147 of the Chilean Companies Act, our Board has resolved that the following transactions with related parties do not need to follow the procedure set forth in the previous paragraph: (i) transactions which do not involve material amounts; (ii) transactions with affiliates in which we control 95% or more of the equity; and (iii) transactions that are considered by our Board to be performed in the ordinary course of our business in accordance with our general policy of customary dealings, which was approved by our Board on December 29, 2009 and is available to shareholders at our main office and is published on our website, at www.arauco.cl.

Article 146 of the Chilean Companies Act defines related party transactions as negotiations, acts, contracts or transactions between the company and any other person or entity that involve the following:

• directors or officers of a corporation (or their respective spouses and certain other relatives) acting on their own;

• directors or officers of a corporation who have a direct or indirect ownership interest of at least 10% of the equity shares of the other company or are also directors or officers of such other company;

• persons who have been in the last 18 months previous to the transaction, directors or officers of the corporation; and

• “related persons” of the corporation, as defined in article 100 of the Chilean Securities Markets Law.

Article 100 of the Chilean Securities Markets Law establishes that the following are “related persons” to a company: (i) the entities of the corporate group (grupo empresarial) to which such company belongs; (ii) the entities that are either parent company, subsidiary, owners of at least 10% of the equity of a company or other companies in which the company owns at least 10%; (iii) directors or officers of the company (or their respective spouses and certain other relatives); (iv) any person who, individually or with other persons under a voting agreement can designate at least one member of the management of the company or control at least 10% of the capital of such company; and (v) any other person who is indicated as such by the Chilean Superintendencia de Valores y Seguros, in accordance with certain parameters established by the above-mentioned Article 100.

Our transactions with affiliates include the following:

• We purchase goods and services that may also be provided by other suppliers. Among the most significant are our fuel purchases from COPEC, a subsidiary of Empresas Copec, our majority shareholder; and

• We purchase port services from our 20.3% affiliates Puertos y Logística S.A. (formerly Puerto de Lirquén S.A.) and Puerto Lirquén S.A. (formerly Portuaria Sur de Chile S.A.), and our 50.0% affiliate Compañía Puerto de Coronel S.A.;

• We purchase from EKA Chile, a chlorate sodium supplier, which is 50% controlled by Arauco, and we provide EKA Chile with electricity; and

• We obtain legal services from Portaluppi, Guzmán y Bezanilla, a law firm of which two of our directors, José Tomás Guzmán and Manuel Bezanilla, are partners.

Financial information concerning transactions with affiliates is included in Note 13 to our audited consolidated financial statements.

Item 8. Financial Information

See “Item 17—Financial Statements.”

EXPORT SALES

Export sales constituted 66.1% of our sales revenue for the year ended December 31, 2012. Our total export sales revenue for 2012 was U.S.$2,829.4 million. Our principal overseas markets are Asia, North America and Western Europe. See “Item 4. Information on the Company—Description of Business—Domestic and Export Sales.”

LEGAL PROCEEDINGS

From time to time, we have been subject to environmental proceedings related to allegations by the Chilean environmental regulators and private parties. We are also subject to certain other legal proceedings arising from the ordinary course of our business. For more information regarding the environmental proceedings and other legal proceedings arising from the ordinary course of business, see Note 18 to our audited consolidated financial statements.

Since the end of 2004, we have been subject to various criminal proceedings relating to alleged violations of several environmental laws in Chile, each of which has been either terminated or abandoned by the prosecutor (decisión de no perseverar) as of the date of this annual report. For instance, on October 18, 2010, in a public hearing held before the San José de la Mariquina’s Criminal Court, the prosecutor in charge of the investigation announced its decision to terminate the investigation due to a lack of information or evidence that could support any theory of criminal liability. Such decision has not been challenged.

While Chilean law in general provides that only individuals can be convicted in criminal actions, Chilean Law Nº 20,393, which was published in the Official Gazette on December 2, 2009, provides an exception to this general rule, under which criminal responsibility of legal entities can be established for criminal offenses related to the financing of terrorism, asset laundering or bribery. We do not have knowledge of any fact that could result in such criminal responsibility for the Company.

Valdivia Mill

Our operations at the Valdivia Mill have been subject to continued environmental scrutiny by Chilean environmental regulators and the Chilean public since the mill began its operations in 2004. There have been allegations of a causal connection between the migration and death of black-neck swans and the operations at the Valdivia mill, and in a study dated April 18, 2005, researchers at the Austral University in Valdivia concluded that wastewater discharges from the Valdivia Mill had significantly altered the quality of the Cruces River. The study also concluded that the effluent discharges were a significant contributing factor in the death or migration of a large population of the black-necked swans in the Carlos Anwandter Nature Sanctuary downstream from the Valdivia Mill. In April 2005, the National Defense Council instituted an action seeking reparations, damages and indemnification from us for environmental harm allegedly caused by the discharges from the Valdivia Mill. In response, we have argued to the court that this action should be rejected, as several studies have demonstrated that there is no relationship between the alleged damages and the operation of the Valdivia Mill. The Valdivia Mill lawsuit remains under review by the court as of the date of this annual report. If the result of the Valdivia Mill lawsuit is unfavorable to us, we may be required to invest a significant amount of funds and/or take other actions to repair any environmental harm a court determines we have caused, which could materially and adversely affect our business, financial condition, results of operations and cash flows. We cannot predict the outcome or impact of this lawsuit or when it may be resolved.

In June 2005, we suspended operations at the Valdivia Mill until certain technical and legal conditions could be clarified with the applicable regulatory authorities. We estimate this suspension resulted in a loss of sales of approximately U.S.$1.0 million per day and a loss of profits of approximately U.S.$250,000 per day. Pursuant to the decision of our board of directors, based on certain clarifications provided by the Environmental Regional Commission (Comisión Regional del Medio Ambiente), or COREMA, of the Tenth Region of Chile, the mill

79

resumed operations in August 2005, after 64 days of suspended operations, at 80% of its authorized production capacity. In order to achieve the full production capacity authorized by applicable permits, the mill had to fulfill certain new requirements established by the COREMA. On January 18, 2008, the COREMA authorized the Valdivia Mill to return to its annual authorized production capacity of 550,000 metric tons. The mill gradually increased its production over a four-month period starting in March 2008 and reached full capacity in June 2008. The suspension of operations at the Valdivia Mill adversely affected our business, financial condition, results of operations and cash flows. Any future suspension of operations at the Valdivia Mill or at any other of our significant operating plants can be expected to have similar adverse effects. We offer no assurance that the Valdivia Mill will be able to operate without further interruption. See “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry—Environmental concerns led to the temporary suspension of our operations at the Valdivia Mill in 2005 and at the Licancel Mill in 2007, which adversely affected, and in the future may continue to adversely affect, our business, financial condition, results of operations and cash flows” and “Item 4. Information on the Company—Description of Business—Pulp—Pulp mills—Chile—Valdivia Mill.”

In June 2007, we submitted to the COREMA of the Tenth Region of Chile an environmental impact study for the implementation of substantial technological improvements on the quality of the effluents generated by the Valdivia Mill. On June 30, 2008, the COREMA approved that environmental impact study. However, the approval was subject to certain conditions that, in our opinion, adversely affected the feasibility of the project. For such reason, we filed an appeal (recurso de reclamación) before the Directive Council (Consejo Directivo) of the Environmental National Commission (Comisión Nacional del Medio Ambiente), or CONAMA, challenging the conditions imposed by the COREMA. Our appeal was partially accepted by the CONAMA, which upheld some of the conditions that we believed would adversely affect the feasibility of the project. Consequently, on September 17, 2009, we presented another appeal before the ordinary courts of justice. On December 5, 2012, the Environmental Evaluation Service of the Tenth Region of Chile authorized certain changes to the project based on the implementation of certain technological improvements. On November 9, 2012, we withdrew our appeal. The court approved the withdrawal on November 29, 2012.

Until October 2007, our Valdivia Mill was under the jurisdiction of the COREMA of the Tenth Region of Chile, but due to a change in legislation creating two new administrative regions in Chile, our Valdivia Mill became subject to the jurisdiction of the COREMA of the Fourteenth Region of Chile. In February 2009, as previously required by the COREMA of the Tenth Region of Chile, we submitted to the COREMA of the Fourteenth Region of Chile an environmental impact study for the construction of a pipeline to discharge the Valdivia Mill’s wastewater in the Pacific Ocean near Punta Maiquillahue, complying with the requirement that such wastewater be discharged in a body of water other than the Cruces River, the Carlos Anwandter Nature Sanctuary or their respective sources. In February 2010, through Exempt Resolution No. 27/2010, the COREMA approved this environmental impact study subject to additional conditions, certain of which we challenged before the Directive Council primarily because they would have prohibited the discharge of wastewater into the Cruces River under any circumstance, including emergencies. On October 23, 2012, the Committee of Ministers passed Exempt Resolution No. 1052, which upheld in part our appeal in permitting the discharge into the Cruces River upon the occurrence of certain contingencies that may affect the normal functioning of the conduction system and/or outfall, including bombings or sabotage, natural disasters, or accidents caused by third parties. On March 29, 2010, two Chilean individuals filed a reclamation action (recurso de participación ciudadana) before the COREMA of the Fourteenth Region of Chile, challenging Exempt Resolution No. 27/2010. As of the date of this annual report, the Committee of Ministers has not issued a resolution concerning this action.

As stated in the environmental impact study, the construction of this pipeline will commence once (i) the COREMA (or the relevant environmental authority under the Chilean Environmental Law) approves the environmental impact study in its final form, and (ii) all necessary permits for the construction of the pipeline have been issued by the competent authorities. In the environmental impact study, we estimated that the construction of the pipeline will take 24 months. Once the construction of the pipeline has been completed, we will conduct a 6-month trial phase of the pipeline and will then begin normal operations.

Resolution of our proceeding with the CONAMA regarding the resolution that approved the environmental impact studies of the pipeline project, as well as the construction and operation of the pipeline, are each subject to many environmental, regulatory, engineering and political uncertainties. As a result, we cannot provide any assurances that the project will be finally approved as requested or completed. If either the request for the necessary

80

permits for the construction of the pipeline is rejected, or the installation of the pipeline is delayed for reasons attributable to us, we may face sanctions that include warnings, fines or the revocation of the Valdivia Mill’s environmental permit for operation. Alternatively, if any rejection or delays are attributable to reasons beyond our control, we believe that the environmental authorities should extend the applicable deadlines. However, we can provide no assurances that any deadline extensions would be granted, even if we comply with all the requirements that may be set forth by those authorities. See “Item 3. Key Information—Risk Factors—Risks Relating to Us and the Forestry Industry—Environmental concerns led to the temporary suspension of our operations at the Valdivia Mill in 2005 and at the Licancel Mill in 2007, which adversely affected, and in the future may continue to adversely affect, our business, financial condition, results of operations and cash flows” and “Item 4. Information on the Company—Description of Business—Pulp—Pulp mills—Chile—Valdivia Mill.”

Licancel Mill

In June 2007, our operations at the Licancel Mill, a pulp mill located in the Seventh Region of Chile, became subject to environmental scrutiny by Chilean environmental regulators and the public. On June 5, 2007, in connection with the death of fish in the Mataquito River, approximately 15 kilometers downstream of the mill, we suspended our operations in the Licancel Mill as a preventive measure. In addition, Chilean authorities, including the health authorities and the Superintendencia de Servicios Sanitarios (Sanitary Services Superintendency), required that we suspend activities at the Licancel Mill and that we suspend any further discharges into the river. On June 18, 2007, as a result of a pipe leakage in the effluent treatment system currently in place at the Licancel Mill, an estimated 50 cubic meters of effluents reached the Mataquito River. On that same date, we decided to close the mill indefinitely and informed the Sanitary Services Superintendency of the incident. On October 3, 2007, we requested to the health authority (Autoridad Sanitaria) of the Seventh Region of Chile that it remove the suspension of activities at the Licancel Mill. On October 22, 2007, the health authority of the Seventh Region of Chile removed the suspension and imposed certain conditions relating to our activities in the mill consisting primarily of the implementation of certain emergency detection and control programs and systems, with which we have complied. Furthermore, on November 12, 2007 the Sanitary Services Superintendency removed the suspension regarding the release of discharges by the Licancel Mill. The mill resumed operations during January 2008, using the new effluent treatment system in which we invested U.S.$8 million during 2007.

On September 7, 2007, the National Defense Council instituted a civil lawsuit seeking reparations, damages and indemnification from us for environmental harm allegedly caused by the Licancel Mill. Although the National Defense Council agreed to terminate this lawsuit pursuant to an agreement with us dated January 29, 2010, several other proceedings have been commenced as a result of the event at the Licancel Mill, including for loss of income arising from the death of fish at the Mataquito River.

Tax Litigation in Argentina

On December 14, 2007, the Administración Federal de Ingresos Públicos (AFIP), Argentina’s internal revenue service, notified our Argentine subsidiary, Alto Paraná S.A., of a claim for unpaid taxes for fiscal years 2002, 2003 and 2004 in the aggregate amount of AR$418 million (or approximately U.S.$105 million) (including principal, interest and penalties accrued through such date), arising from a dispute regarding certain income tax deductions (related to debt issued by Alto Paraná in 2001 and repaid in 2007) taken by Alto Paraná and rejected by the AFIP. On February 8, 2010, the Tribunal Fiscal de la Nación (Argentina’s tax court) issued an unfavorable administrative ruling requiring that Alto Paraná pay the AFIP’s claim in full.

Alto Paraná appealed this unfavorable administrative ruling to the Court of Appeals and also filed an injunctive action requesting that the court stay Alto Paraná’s payment obligation until resolution of its pending appeal. On May 13, 2010, the Court of Appeals granted an injunction of Alto Paraná’s payment obligation in exchange for the posting of a surety bond in the amount of AR$633.6 million (or approximately U.S.$129 million). On December 28, 2012, the Court of Appeals dismissed Alto Paraná’s appeal. Alto Paraná appealed this decision before the Argentine Supreme Court of Justice (“Supreme Court”). The appeal, once conceded, will suspend the execution of the decision ruled by the Court of Appeals.

We have not established any reserve in respect of this contingency and can offer no assurance that the Supreme Court will issue a ruling favorable to us. If the Supreme Court upholds the decision of the Court of Appeals, Alto Paraná will be required to satisfy the above-mentioned claim, an outcome that would have an adverse effect on our financial condition and results of operations.

Tax Litigation in Chile

On August 25, 2005, the Chilean Servicio de Impuestos Internos (the “Chilean IRS”) issued tax calculations No. 184 and No. 185 of 2005 objecting to certain capital reduction transactions effected by Arauco on April 16, 2001 and October 31, 2001, and furthermore, requested reimbursement from the Company for amounts returned to it in respect of certain claimed tax losses. On November 7, 2005, the Company requested a Review of the Supervision Action (Revisión de la Actuación Fiscalizadora, or “RAF”), which is an administrative review of the tax action brought by the Chilean IRS, and subsidiarily, a claim was filed against the above-mentioned tax calculations No. 184 and 185 of 2005. The RAF was resolved on January 9, 2009 by the Chilean IRS, which resolution, however, only partially sustained the Company’s request. In response, the Company filed an additional complaint with regard to the portion of the RAF that was not granted by the administrative review. As of the date of this annual report, the investigation in respect of this complaint is pending.

The Company believes that its position in respect of this complaint is supported by solid legal arguments and that there is a reasonable likelihood that this matter will result in a favorable outcome for the Company. However, if this result does not occur, it is possible that an obligation will arise for the amount specified, which was Ch$3,362,265,453, plus any accrued interest as of the payment date.

Tax Litigation in Brazil

On November 8, 2012, Brazilian Tax Authorities issued an Infraction Notice against one of our Brazilian subsidiaries, Arauco do Brasil S.A., for alleged unpaid taxes purportedly due by such company for the years 2006 to 2010 in the aggregate amount of R$172 million (approximately US$85 million). In particular, the Tax Authorities (i) objected to the deductibility of certain payments made and expenses incurred (including premium amortization, interest and legal expenses) by Arauco do Brasil between 2005 and 2010 and (ii) alleged that Arauco do Brasil made certain underpayments in respect of the Brazilian Corporate Income Tax (“IRPJ”) and the Brazilian Social Contribution on Net Profits (“CSL”) during 2010. Currently, the aggregate amount of the claims asserted in the Infraction Notice, plus interest, correspond to R$177 million (approximately US$88 million).

On December 11, 2012, Arauco do Brasil filed an objection to cancel the Infraction Notice before the Judgment Office of the Brazilian Revenue Service, first administrative level. As of the date of this annual report, judgment in respect of this objection remains pending. The Company believes that its objection to the Infraction Notice is supported by solid legal arguments and that there is a reasonable likelihood that this matter will result in a favorable outcome for the Company. However, if this result does not occur, it is possible that an obligation will arise for the amount specified, plus any accrued interest and penalties as of the payment date.

DIVIDEND POLICY

Chilean law currently requires that, unless otherwise decided by the unanimous vote of our issued and subscribed shares eligible to vote, public corporations distribute a cash dividend in an amount equal to at least 30% of the corporation’s consolidated net income for each year on the basis of IFRS, unless and except to the extent the corporation has unabsorbed losses from prior years. In April 2002, our shareholders approved the current dividend policy, setting the cash dividend at 40% of our consolidated net income for each year which was determined on a Chilean GAAP basis through the year ended December 31, 2008, and as of January 1, 2009, is now determined on an IFRS basis. In accordance with IFRS, the determination of the dividend amount is based on the effective realized profit net of any relevant variations in the value of unrealized assets and liabilities.

On April 27, 2010, our shareholders approved a final dividend of U.S.$0.5016 per share for 2009, which was distributed on May 11, 2010. In the aggregate, dividends distributed equaled 40% of our consolidated net income for 2009 as determined on an IFRS basis. On November 23, 2010, our board of directors approved an interim dividend of U.S.$0.7557 per share, which was distributed on December 15, 2010 and charged to net income. On April 26, 2011 our shareholders approved a final dividend of U.S.$1.6152 per share for 2010, which was distributed on May 11, 2011. Dividends distributed equaled 40% of our consolidated net income for 2010 as determined on an IFRS basis. On November 22, 2011, our board of directors approved an interim dividend of U.S.$0.78 (rounded) per share, which was distributed on December 14, 2011 and charged to net income. On April 24, 2012 our shareholders approved a final dividend of U.S.$1.4278819 per share for 2011, which was distributed on May 9, 2012. Dividends distributed equaled 40% of our consolidated net income for 2012 as determined on an IFRS basis. On November 28, 2012, our board of directors approved an interim dividend of U.S.$ 0.15308 per share, wich was distributed on December 12, 2012.

Although the board of directors has no current plans to recommend changes in our dividend policy, the policy has been changed in the past and no assurance can be given that the policy will not be changed in the future, due to changes in Chilean law, capital requirements, operating results or other factors.

Item 9. The Offer and Listing

Neither our stock nor our SEC-registered securities are listed on any stock exchange or other regulated market.

Trading in our securities takes place primarily in the over-the-counter market. Accordingly, we are unable to obtain reliable information on such trading.

Item 10. Additional Information

ARTICLES OF INCORPORATION AND BY-LAWS

When we refer to the “Company,” “Arauco” or “we,” in this description of the articles of incorporation and by-laws, we mean Celulosa Arauco y Constitución S.A.

Organization and Registration

We are a corporation (sociedad anónima) organized in Chile under the laws of Chile, subject to certain rules applicable to Chilean public corporations (sociedades anónima abiertas) and registered on August 18, 1971, by resolution 300-S of the Chilean Securities Commission and recorded in the Santiago Commercial Register of 1971 on page 6433 under entry number 2994 and on page 6431 under entry number 2993. Notice was published in the Official Gazette on September 4, 1971.

Objects and Purposes

Our purpose, as stated in our by-laws (estatutos), includes the manufacture of forestry products, the management of forestry lands and other activities.

Capital

In 2002, our by-laws were amended such that our capital is denominated in U.S. dollars. In 2002, we and two of our subsidiaries, Aserraderos Arauco and Paneles Arauco, received authorization from the Chilean IRS to prepare our audited consolidated financial statements in U.S. dollars, beginning January 1, 2002. In January 1, 2003, our subsidiaries Forestal Arauco, Bosques Arauco, Forestal Valdivia, Forestal Celco and Cholguán obtained the same permission from the Chilean IRS. The same permission from the Chilean IRS was obtained by our subsidiary Inversiones Arauco Internacional Ltda. in January 2003, by our subsidiary Forestal Los Lagos in January 2005 and by our subsidiaries Arauco Bioenergía S.A. and Servicios Logísticos Arauco S.A in January 2008.

Directors

Pursuant to our by-laws, our board of directors is composed of nine members elected by a general meeting of our shareholders. Our directors are not required to be shareholders. Our by-laws state that the amount of compensation to be received by the directors for their directorial services shall be fixed by the general shareholders’ meeting. Directors may be compensated for any non-directorial services rendered to us at levels of compensation comparable with compensation commonly paid for these services, compensation which is compatible with the directors’ compensation fixed by the general shareholders’ meeting. The by-laws also state that our board of directors has all of the authorities of administration and disposal that Chilean law or the by-laws do not confer upon the general shareholders’ meeting. The board of directors has the right to act on our behalf without the need for a special power of attorney, even in cases where a power of attorney is required by law. In particular, the by-laws provide that the board of directors is empowered to encumber our assets, real and personal property with mortgages, easements or pledges regardless of the value of such property or the amount of the respective encumbrances and to borrow money paying interest, with or without a guaranty for the loan.

Our by-laws provide that we may enter into acts or contracts in which one or more directors are interested only if the interested director’s interest is made known to the board, the acts or contracts are approved by the board and the terms of the act or contract conform to those prevailing in the market. In addition, board resolutions approving interested director transactions must be reported by the chair of the meeting at the first general shareholders’ meeting following the approval of the interested director transaction.

See “Item 6. Directors, Senior Management and Employees” for further information about our board of directors.

83

Shareholders

Our share capital consists of ordinary shares of no par value issued in registered form. Record holders of shares are registered in our share register. Any transfer of shares must be noted in our share register.

Voting Rights

Each share of our stock entitles the holder to one vote at any meeting of shareholders. Resolutions may be taken upon a vote of an absolute majority of the voting shares present or represented. Any resolution relating to amendments to our by-laws must be approved by an absolute majority of the voting shares issued. Resolutions with regard to the following matters, among others, require the affirmative vote of two-thirds of the voting shares issued:

• transformation, including division or merger with another company;

• advanced dissolution;

• change of corporate domicile;

• reduction in our equity capital;

• approval and appraisal of non-cash capital contributions;

• reduction in the number of members of the board of directors;

• the disposal of 50% or more of our assets, whether or not such disposal also includes any of our liabilities; the disposal of 50% or more of the assets of one our subsidiaries, provided that such subsidiary represents at least 20% of our assets; and any disposal of shares by the company that causes us to lose control of a subsidiary that represents at least 20% of our assets; and

• changes to the way in which corporate benefits will be distributed.

According to our by-laws, holders of our shares also have the right to vote at the general shareholders’ meeting for the election of directors. Shareholders or their representatives may accumulate their votes in favor of one candidate or distribute them among various candidates. A vote on the election of directors may be omitted if an election is proposed by acclamation and none of the shareholders present or represented opposes the motion. The board of directors may also be dismissed by a regular or special general shareholders’ meeting, though the shareholders may only vote to dismiss the board as a whole.

Changes to Shareholders’ Rights

To change the rights of holders of our shares or create a new series of our shares, we must amend our by-laws. Any reduction in the number of our shares requires a two-thirds majority vote of all holders of our shares under Chilean law. Chilean law also requires that public corporations distribute a cash dividend in an amount equal to at least 30% of the corporation’s consolidated net income for each year (on an IFRS basis), unless otherwise decided by a unanimous vote of the corporation’s issued and subscribed shares eligible to vote. Any changes to the way in which corporate benefits are distributed must be approved by a two-thirds majority of all holders of the corporation’s shares.

Shareholders’ Meetings

Our by-laws provide that the board of directors shall call general shareholders’ meetings. Notice of general shareholders’ meetings must be made by a prominent notice published at least three times, on different days, in the newspaper of one of our corporate domiciles, as determined by a general shareholders’ meeting, or in the absence of a determination, in the Official Gazette.

84

A shareholder must be registered in our share register as of the meeting date to be entitled to participate and vote at any shareholders’ meeting. In addition, other persons may represent shareholders at general meetings. Powers of attorney must be given in writing and must be granted with respect to all of the shares the shareholder is entitled to vote as of the date five days before the general shareholders’ meeting.

General shareholders’ meetings may be regular or special meetings. Regular shareholders’ meetings are held once a year within the first four months of the year. Among other things, the regular general shareholders’ meeting appoints independent external auditors to examine our accounts, inventory, balance sheet and other financial results. The by-laws provide that the following matters are to be considered at regular shareholders’ meetings:

• the review of our results of operations and external auditors’ reports and the approval or rejection of our annual report, our balance sheet and financial statements;

• the distribution of profits of each financial period and the distribution of our dividends;

• the election or dismissal of the members of the board of directors; and

• any matter of corporate interest that is not transacted at a special general shareholders’ meeting.

Special shareholders’ meetings may be held at any time required by corporate needs to consider any matter that the law or our by-laws require to be considered at a general shareholders’ meeting. Our by-laws require the meeting notice to disclose any matters to be discussed at a special shareholders’ meeting. According to the by-laws, the following matters must be considered at special shareholders’ meetings:

• dissolution;

• transformation, merger or division and the amendment of our by-laws;

• the issue of bonds or debentures convertible into shares;

• the disposal of 50% or more of our assets, whether or not such disposal also includes any of our liabilities; the disposal of 50% or more of the assets of one our subsidiaries, provided that such subsidiary represents at least 20% of our assets; and any disposal of shares by the company that causes us to lose control of a subsidiary that represents at least 20% of our assets; and

• the grant of real or personal guarantees to secure obligations of third parties, unless they are subsidiaries, in which case the approval of the board of directors will be sufficient.

Any other matters within the competence of general shareholders’ meetings may be considered at special shareholders’ meetings.

Any act of a general shareholders’ meeting relating to our dissolution, transformation, merger or division, the amendment of our by-laws, any disposal of 50% or more of our assets or the issue of bonds convertible into shares or convertible debentures must be held before a notary public, who must certify that the minutes of such meeting are the true expression of what occurred and was resolved at such meeting.

Allocation of Net Income and Distribution of Dividends

Our by-laws provide that the shareholders at a general shareholders’ meeting shall determine the annual distribution of our net profits for each financial period, within the limitations prescribed by law. The shareholders shall also set the date on which any distribution shall be paid, within the time limits prescribed by law. Chilean law prescribes that distributions shall be paid within 30 days of the general shareholders’ meeting at which such distribution was determined.

85

In accordance with Chilean law, in the event of liquidation, capital can be distributed to the shareholders only after the rights of the creditors have been secured or debts owed to creditors have been paid. Our by-laws provide that a general shareholders’ meeting will appoint one or more liquidators to carry out the liquidation and to call shareholders’ meetings, as required under Chilean law.

Regulation of and Restrictions on Foreign Investors

There are no limitations on the rights to hold securities, including rights of non-resident or foreign shareholders to hold or exercise voting rights on securities.

Disclosure of Shareholder Ownership

We register certain information about our shareholders in our shareholder registry. We are required to disclose this information to the Chilean Securities Commission on a quarterly basis.

Rights of Shareholders

Our by-laws provide that, in the case of a dispute between shareholders or between shareholders and management, the parties will submit their dispute to a mixed arbitrator, who may determine the procedural rules to be used in the arbitration but must issue a final judgment in accordance with Chilean law. Subject to limited exceptions, the arbitrator’s judgment shall not be subject to appeal. The parties shall appoint the arbitrator by mutual agreement and if no agreement is reached, an arbitrator will be appointed by the civil court system from among present and former associate justices of the Supreme Court of Justice of Chile.

EXCHANGE CONTROLS

The Central Bank is responsible for, among other things, monetary policies and exchange controls in Chile. Prior to 1989, Chilean law permitted the purchase and sale of foreign currency only in cases explicitly authorized by the Central Bank. Law No. 18,840, the Organic Law of the Central Bank of Chile (Ley Orgánica Constitucional del Banco Central de Chile), or the Central Bank Act, enacted in 1989, liberalized the rules that govern the ability to buy and sell foreign currency.

The Central Bank Act empowers the Central Bank to determine which types of foreign exchange operations must be carried out in the Formal Exchange Market rather than the Informal Exchange Market (Mercado Cambiario Informal). The Central Bank has ruled that certain foreign exchange transactions, including those attendant to foreign investments and bond issuances, may be effected only in the Formal Exchange Market. The Central Bank may also impose restrictions on foreign exchange operations that are conducted or are required to be conducted in the Formal Exchange Market. These restrictions may include the requirement of prior authorization from the Central Bank, the imposition of reserve requirements and the limitation of foreign exchange operations that may be conducted by the entities that participate in the Formal Exchange Market.

The Formal Exchange Market consists of banks and other entities authorized by the Central Bank to participate in such Formal Exchange Market. On April 16, 2001, the Central Bank agreed that, effective April 19, 2001, the prior foreign exchange restrictions would be eliminated and a new Compendium of Foreign Exchange Regulations (Compendio de Normas de Cambios Internacionales) would be applied.

The main objective of this change was to facilitate capital movements from and into Chile and to encourage foreign investment.

The following specific restrictions were eliminated:

• a reserve requirement with the Central Bank for a period of one year;

• the requirement for prior approval by the Central Bank for certain operations, such as repatriation of investments and payments to foreign creditors;

86

• the mandatory return of foreign currencies to Chile; and

• the mandatory conversion of foreign currencies into Chilean pesos.

Under the amended regulations, only the following limitations are applicable to these operations:

• the Central Bank must be provided with information related to certain operations, such as foreign investments and foreign credits; and

• certain operations, such as money transfers to and from Chile related to foreign investments and foreign credits, must be conducted within the Formal Exchange Market.

International Issue of Bonds

Before April 19, 2001, any international issue of bonds was subject to approval by the Central Bank after submission of an application to the Central Bank through a bank or other participant in the Formal Exchange Market. Absent the Central Bank’s authorization, issuers were unable to offer bonds outside of Chile. On April 19, 2001, the Central Bank issued new foreign exchange regulations, effective as of March 1, 2002, that were included in the new Chapters XIV and VIII of the Compendium, applicable to bond issues made either from Chile or through an agency abroad. It must be noted however, that all debt issues made before the new regulations remain subject to the regulations existing at the time of their issue.

Debt Securities Issued Directly By Us

In accordance with the regulations issued by the Central Bank, which are included in the new Chapter XIV of the Compendium, any international issue of bonds in an aggregate amount exceeding U.S.$1,000,000 must be registered and dated by the Central Bank or by a bank or other entity authorized by the Central Bank to participate in the Formal Exchange Market before the proceeds from the issuance can be remitted to Chile and received by the issuer or simultaneously with the remittance into Chile of such proceeds. The issuer must submit forms regarding the offering to the registering entity or directly to the Central Bank, along with a letter of instructions indicating whether it prefers to receive the proceeds in Chilean pesos or in a foreign currency. If presented through a Formal Exchange Market entity, such entity must, in turn, verify that the forms submitted by the issuer are in accordance with the documentation relating to the issue and inform the Central Bank of the operation no later than 11:00 a.m. on the banking business day following the date on which the proceeds of the issue are transferred to the issuer.

If the issuer opts to receive the proceeds of the issue outside of Chile, it must report this to the Central Bank directly or through a Formal Exchange Market entity during the first ten calendar days of the month following the one in which the proceeds were received.

Chapter XIV of the Compendium also states that proceeds from the issue, as well as payment of capital and interest relating to the issue, must be received and sent from and through the Formal Exchange Market, but purchases of U.S. dollars in connection with payments on debt securities issued directly by us can be made either in the Formal or in the Informal Exchange Market. There can be no assurance, however, that we will be able to purchase U.S. dollars in the Informal Exchange Market or in the Formal Exchange Market at the time or in the amounts required to pay debt service related to any such debt securities. There can also be no assurance that further Central Bank regulations or legislative changes to the current foreign exchange control regime in Chile would not restrict or prevent our purchase of U.S. dollars to make payments under our securities.

In the case of debt securities issued directly by us before the effectiveness of the new regulations, the registration of the debt securities with the Central Bank grants us access to the Formal Exchange Market for the purchase of U.S. dollars necessary to make payments in respect of those securities but requires that payments on such debt securities shall be made only with U.S. dollars purchased in the Formal Exchange Market.

We will also be required to inform the Central Bank quarterly of the outstanding amounts due under our securities and from time to time of any information that has been previously filed.

87

The regulations of Chapter XIV of the Compendium do not make any reference to the one-year mandatory deposit in the Central Bank that was previously required by Chapter XIV. However, the Central Bank is authorized, under the Central Bank Act, to impose such a requirement.

Debt Securities Issued Through Our Panamanian Agency

In December 1996, we established a registered agency in Panama. We may from time to time issue debt securities directly or through our Panamanian agency depending on, among other factors, whether or not we expect to bring the proceeds thereof into Chile. In such cases, the proceeds of such issuance of the notes may be brought into Chile or held abroad. In either case, however, in accordance with Chapter VIII of the Compendium, we were required to inform the Central Bank of the issuance of international bonds through our Panamanian agency during the first ten calendar days of the month following the one in which the disbursement of funds to the agency was produced, and provide the schedule of payments of the notes. On December 27, 2007, the requirement to provide such information to the Central Bank was eliminated. We will no longer be required to inform the Central Bank of future issuances of bonds made through our Panamanian agency.

Purchases of U.S. dollars in connection with payments on debt securities issued through our Panamanian agency, whether before or after April 19, 2001, can be made either in the Formal Exchange Market or in the Informal Exchange Market. Although we were required to inform the Central Bank of the issuance of debt securities through our Panamanian agency, such communication to the Central Bank did not give us access to the Formal Exchange Market for the purchase of U.S. dollars necessary to make payments in respect of those debt securities.

There can be no assurance that we will be able to purchase U.S. dollars in the Informal Exchange Market or in the Formal Exchange Market at the time or in the amounts required to pay debt service related to any such debt securities. There can also be no assurance that further Central Bank regulations or legislative changes to the current foreign exchange control regime in Chile and will not restrict or prevent our purchase of U.S. dollars to make payments under our securities from Chile.

TAXATION

General

The following summary contains a description of the principal Chilean and United States federal income tax consequences of the purchase, ownership and disposition of our securities, but it does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to purchase our securities. This summary does not describe any tax consequences arising under the laws of any state, locality or taxing jurisdiction other than the United States and Chile.

This summary is based on the tax laws of Chile and the United States as in effect on the date of this Form 20-F, as well as regulations, rulings and decisions of Chile and the United States available on or before such date and now in effect. All of the foregoing is subject to change, and any changes could apply retroactively and could affect the continued validity of this summary.

Prospective purchasers of our securities should consult their own tax advisors as to the Chilean, United States or other tax consequences of the purchase, ownership and disposition of our securities, including, in particular, the application to their particular situations of the tax considerations discussed below, as well as the application of state, local, foreign or other tax laws.

Chile and the United States have executed an income and capital tax treaty for the avoidance of double taxation and the prevention of fiscal evasion, but this treaty is not in effect, and its effectiveness is contingent upon ratification in the United States Senate and by the Chilean Congress. At this time it is not clear when the United States Senate and the Chilean Congress will consider ratification, and therefore the effective date of the treaty is uncertain.

88

Chilean Taxation

The following is a general summary of the principal consequences under Chilean tax law, as currently in effect, of an investment in our securities made by a foreign holder. Foreign holder means either:

• in the case of an individual, a person who neither is a resident nor is domiciled in Chile. For Chilean tax purposes, an individual is domiciled in Chile if such individual has his or her principal place of business in Chile. The individual will be considered as a resident if she or he stays in Chile for more than six months in one calendar year or a total of more than six months in two consecutive fiscal years; or

• in the case of a legal entity, a legal entity that is not organized under the laws of Chile, unless our securities are assigned to a branch or a permanent establishment of such entity in Chile.

Under Chile’s income tax law, our payments of interest made from Chile in respect of our securities to a foreign holder will generally be subject to a Chilean withholding tax assessed at a rate of 4.0% (the “Chilean Interest Withholding Tax”).

We have agreed, subject to specific exceptions and limitations, to pay to the foreign holders of notes additional amounts in respect of the Chilean Interest Withholding Tax in order to ensure that the interest amount the foreign holder receives is net of Chilean Interest Withholding Tax. If we pay additional amounts in respect of the Chilean Interest Withholding Tax, any tax refunds in respect of these amounts will be for the benefit of the company. In the event that certain changes in Chilean tax laws require us to pay additional interest amounts in respect of the Chilean Interest Withholding Tax at a rate in excess of 4.0%, we have the right to redeem our securities.

Under existing Chilean law and regulations, a foreign holder will not be subject to any Chilean taxes in respect of payments of principal that we make with respect to our securities. Our payments with respect to our securities of amounts not considered principal or interest may be subject to a Chilean withholding tax of up to 35%.

The Chilean Income Tax Law provides that a foreign holder is subject to income tax on his Chilean source income. For this purpose, Chilean source income means earnings from activities developed in Chile or goods located in the country. According to the Chilean Income Tax Law, the source of interest income corresponds to the residence country of the debtor. Under these rules, the capital gain realized on the sale or other disposition by a foreign holder of our securities generally will not be subject to withholding taxes on capital gains, provided that the sale or disposition occurs outside of Chile.

A foreign holder will not be liable for gift, inheritance or similar taxes with respect to its holdings unless the securities held by a foreign holder:

• are located in Chile at the time of such foreign holder’s death, or

• are located outside of Chile, but were purchased or acquired with funds derived from Chilean source income.

A foreign holder should not be liable for Chilean stamp, registration or similar taxes.

The issue of our securities directly by us was subject to the Chilean stamp tax, which we paid. The issue of our securities through our Panamanian Branch was not subject to a stamp tax.

United States Taxation

This summary of certain United States federal income tax considerations deals principally with United States Holders that acquired our securities as part of the initial offering of our securities, hold our securities as capital assets and whose functional currency is the United States dollar. It does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular investor, and generally does not

89

address the tax treatment of United States Holders that may be subject to special tax rules, such as banks, financial institutions, tax-exempt entities, regulated investment companies, real estate investment trusts, insurance companies, partnerships and partners therein, dealers in securities or currencies, traders in securities electing to mark to market, certain short-term holders of our securities, persons that will hold our securities as a position in a “straddle” or conversion transaction, or as part of a “synthetic security” or other integrated financial transaction, persons that own (or are deemed to own for United States tax purposes) 10% or more of our voting stock or persons that are not United States Holders. United States Holders should be aware that the U.S. federal income tax consequences of holding our securities may be materially different for investors described in the previous sentence, including as a result of certain laws applicable to investors with short holding periods or that engage in hedging transactions.

As used under this section “United States Taxation,” the term “United States Holder” means a beneficial owner of a Note that is a citizen or resident of the United States or a United States domestic corporation or that otherwise is subject to United States federal income taxation on a net income basis in respect of our securities.

Taxation of Interest and Additional Amounts

A United States Holder will treat the gross amount of interest and Additional Amounts (i.e., without reduction for Chilean Interest Withholding Tax, determined utilizing the 4.0% Chilean Interest Withholding Tax rate applicable to all United States Holders of our securities) as ordinary interest income in respect of our securities at the time that such payments are accrued or are received, in accordance with the United States Holder’s method of tax accounting. Any Chilean Interest Withholding Tax paid will be treated as foreign income taxes eligible for credit against such United States Holder’s United States federal income tax liability, subject to generally applicable limitations and conditions, or, at the election of such United States Holder, for deduction in computing such United States Holder’s taxable income. Interest and Additional Amounts will constitute income from sources outside the United States for foreign tax credit purposes. Such income generally will constitute “passive category income.” Foreign tax credits will not be allowed for withholding taxes imposed in respect of certain short-term or hedged positions in securities and may not be allowed for withholding taxes imposed in respect of arrangements in which a United States Holder’s expected economic profit is insubstantial. United States Holders should consult their own advisors concerning the implications of these rules in light of their particular circumstances.

The calculation of foreign tax credits and, in the case of a United States Holder that elects to deduct foreign taxes, the availability of deductions, involves the application of rules that depend on a United States Holder’s particular circumstances. United States Holders should consult their own tax advisors regarding the availability of foreign tax credits and the treatment of Additional Amounts.

A Holder of our securities that is, with respect to the United States, a foreign corporation or a nonresident alien individual (a “Non-U.S. Holder”) generally will not be subject to United States federal income or withholding tax on interest income or Additional Amounts earned in respect of our securities, unless such income is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States.

Taxation of Dispositions

A United States Holder will generally recognize gain or loss on the sale, exchange or other disposition of a security in an amount equal to the difference between the amount realized on the sale, exchange or other disposition and the tax basis in the security. If Chilean income tax is withheld on the sale, exchange or other disposition of our securities, the amount realized by a U.S. holder will include the gross amount of the proceeds of that sale, exchange or other disposition before deduction of the Chilean income tax. A United States Holder’s tax basis in a security will generally equal its cost. Gain or loss realized by a United States Holder on the sale, redemption or other disposition of our securities generally will be treated as capital gain or loss and such gain or loss will be long-term capital gain or loss if at the time of the disposition, our securities have been held for more than one year. The net amount of long-term capital gain realized by a United States Holder that is an individual is generally taxed at a reduced rate. Gain, if any, realized by a United States Holder generally will be treated as U.S. source income for U.S. foreign tax credit purposes. Consequently, in the case of gain from the disposition of securities that is subject to Chilean income tax, a United States Holder may not be able to benefit from the foreign tax credit for that Chilean income tax, unless the United States Holder can apply the credit against U.S. federal income tax payable on other income from foreign sources. Alternatively, the United States Holder may generally elect to take a deduction for the Chilean income tax paid. The rules governing foreign tax credits are complex and a United States Holder should consult its own tax advisor regarding the availability of foreign tax credits under its particular circumstances.

90

A Non-U.S. Holder of our securities will not be subject to United States federal income or withholding tax on gain realized on the sale or other disposition of our securities unless (i) such gain is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States or (ii) in the case of gain realized by an individual Non-U.S. Holder, the Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met.

Backup Withholding and Information Reporting

Payments of principal, premium, if any, and interest on our securities and payment of the proceeds of any disposition of our securities made to certain United States Holders may be subject to U.S. information reporting requirements. In addition, certain United States Holders may be subject to a U.S. backup withholding tax in respect of such payments if they do not provide their taxpayer identification numbers to the payor or otherwise establish an exemption. Non-U.S. Holders generally are exempt from these withholding and reporting requirements, but may be required to comply with applicable certification and identification procedures to establish their eligibility for such an exemption.

Item 11. Quantitative and Qualitative Disclosures About Market Risk

The following discussion about our risk management activities includes forward-looking statements that involve risk and uncertainties. Actual results could differ materially from those projected in such forward-looking statements.

We are exposed to market risk from changes in interest rates and currency exchange rates. Our board of directors approves our policies that address these risks. From time to time, we assess our exposure and monitor opportunities to manage these risks, including entering into derivative contracts. For information on the currency and interest rate swaps into which we enter with respect to a portion of our borrowings, see “Item 5. Operating and Financial Review and Prospects—Hedging” and Note 23 to our audited consolidated financial statements. In the normal course of business, we also face risks that are either non-financial or non-quantifiable. Such risks principally include country risk, credit risk and legal risk and are not represented in the tables below.

Interest Rate Risk

Interest rate risk exists principally with respect to our indebtedness that bears interest at floating rates. As of December 31, 2012, we had outstanding U.S.$4,324.7 million of indebtedness, excluding accrued interest and discounts and costs of issuance, of which 87.4% bore interest at fixed interest rates and 12.6% bore interest at floating rates of interest. These average rates do not reflect the effect of swap agreements. 76.4% of our indebtedness was denominated in U.S. dollars as of that date. The interest rate on our variable rate debt is determined principally by reference to LIBOR.

91

The following table summarizes our debt obligations, as of December 31, 2012. These obligations are sensitive to changes in interest rates. The table presents the aggregate principal amount of each category of indebtedness maturing in each year, at the weighted average interest rate for each category of indebtedness. Average interest rates for liabilities are calculated based on the prevailing interest rate for each loan as of December 31, 2012.

Foreign Currency Risk

Our principal exchange rate risk involves changes in the value of the Chilean peso and, to a lesser extent, the Brazilian real, the Argentine peso and the euro relative to the dollar. We estimate that a majority of our consolidated costs and expenses are denominated in dollars. As of December 31, 2012:

• 67% of our accounts receivable were denominated in U.S. dollars and 18% in Chilean pesos;

• 82% of our cash and short-term investments were denominated in U.S. dollars, 6% were denominated in Chilean pesos and 0% in euros;

• a significant portion of our indebtedness was denominated in U.S. dollars; and

• a significant portion of our consolidated total assets was denominated in U.S. dollars.

Substantially all of our foreign currency-denominated revenues, costs and expenses, receivables and indebtedness are denominated in U.S. dollars. As of December 31, 2012, 73.4% of our long-term debt was denominated in U.S. dollars. Accordingly, variations in the value of the Chilean peso relative to the U.S. dollar will not have a significant effect on the cost in U.S. dollars of our foreign debt service obligations.

Commodity Risk

Prices for pulp and forestry and wood products can fluctuate significantly, and our sales revenue is highly sensitive to fluctuations in such prices. For a more detailed discussion and sensitivity analysis relating to the risks arising from changes in the market price of pulp, which is our primary commodity risk, see Note 23 to our audited consolidated financial statements. As of December 31, 2012, we were not party to any commodity hedging arrangements.

Item 13. Defaults, Dividend Arrearages and Delinquencies

None.

Item 14. Material Modifications to the Rights of Security Holders and Use of Proceeds

None.

Item 15. Controls and Procedures

(a) Disclosure controls and procedures. We carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Senior Vice-President Comptroller, of the effectiveness of the design and operation of our disclosure controls and procedures, as of December 31, 2012 There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Senior Vice-President Comptroller concluded that the disclosure controls and procedures, as of December 31, 2012, were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the U.S. Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Senior Vice-President Comptroller, as appropriate to allow timely decisions regarding required disclosure.

(b) Management’s annual report on internal controls and procedures. Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Under the supervision and with the participation of our management, including our Chief Executive Officer and Senior Vice-President Comptroller, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS. Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Based on our evaluation under the framework in Internal Control—Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2012.

(c) Attestation Report of the registered public accounting firm. Not applicable.

(d) Changes in internal controls over financial reporting. There has been no change in our internal control over financial reporting during 2012 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 16A. Audit Committee Financial Expert

We do not have an audit committee. Accordingly, certain rules under the U.S. federal securities laws that would otherwise apply to the audit committee apply to our board of directors as a whole. We believe that the members of our board of directors have sufficient financial and other experience to perform their responsibilities under these rules. Our board of directors has determined that Timothy C. Purcell qualifies as an “audit committee financial expert” within the meaning of Item 16A of Form 20-F and is independent as that term is defined in Rule 10A-3 under the Exchange Act. For a description of Mr. Purcell’s professional experience, see “Item 6. Directors, Senior Management and Employees—Directors and Executive Officers.”

Item 16B. Code of Ethics

We have adopted a code of ethics, as defined in Item 16B of Form 20-F under the Securities Exchange Act of 1934, as amended. Our code of ethics applies to all of our employees, including, but not limited to, our Chief Executive Officer, Chief Financial Officer and Senior Vice-President Comptroller. We will provide any person without charge, upon request, a copy of such code of ethics. Requests for a copy of the code of ethics may be made to Celulosa Arauco y Constitución S.A., El Golf 150, 14^th Floor, Santiago, Chile, Attn: Gianfranco Truffello, tel. (011-562) 2461-7200, fax (011-562) 2461-7541. Our code of ethics is also published on our website at www.arauco.cl. If we amend the provisions of our code of ethics that apply to our Chief Executive Officer, Chief Financial Officer and Senior Vice-President Comptroller, or if we grant any waiver of such provisions, we will disclose the amendment or waiver in our annual report on Form 20-F.

Item 16C. Principal Accountant Fees and Services

Audit Committee Approval Policies and Procedures

Our board of directors has established pre-approval policies and procedures for the engagement of our independent auditors. Pursuant to our pre-approval policy, our board of directors has pre-approved a list of services that our independent auditors are allowed to provide to us or our subsidiaries.

Additionally, our board of directors expressly approves, on a case-by-case basis, any engagement of our independent auditors for audit and non-audit services that are not included on the pre-approved list.

All services described in each of paragraphs (b) through (d) of this Item were approved by the board of directors pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Item 16D. Exemptions from the Listing Standards for Audit Committees

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers

Item 16F. Change in Registrant’s Certifying Accountant

On April 3, 2012, the Board of Directors resolved to propose a change to the Company’s independent registered public accounting firm at the General Shareholders’ Meeting held on April 24, 2012. On such date, our shareholders approved the Board of Directors’ proposal to nominate Deloitte as the new independent registered public accounting firm for the Company, and the Company discharged PWC. PWC served as the independent registered public accounting firm for the Company for the 2011 and 2010 fiscal years, in each case pursuant to the terms of an annual engagement letter.

None of the audit reports of PWC relating to the Company’s consolidated financial statements as of and for the years ended December 31, 2011 and 2010 contained any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal years ended December 31, 2011 and December 31, 2010, and the subsequent interim period through April 3, 2012, there were no disagreements with PWC, on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PWC would have caused PWC to make reference thereto in their reports on the Company’s consolidated financial statements for such periods.

95

During the Company’s fiscal years ended December 31, 2011 and December 31, 2010, and the subsequent interim period through April 3, 2012, there were no reportable events (as defined in Item 16F(a)(1)(v) of Form 20-F).

The Company has provided PWC with a copy of this Form 20-F prior to its filing with the Securities and Exchange Commission (“SEC”). The Company requested that PWC furnish the Company with a letter addressed to the SEC stating whether or not it agrees with the above statements, as required by Item 16F(a)(3) of Form 20-F. Such letter is filed as Exhibit 15.1.

During the Company’s fiscal years ended December 31, 2011 and December 31, 2010 and any subsequent interim periods prior to the Company’s engagement of Deloitte, neither the Company nor anyone acting on its behalf has consulted Deloitte on any of the matters or events set forth in Item 16F(a)(2)(i) and Item 16F(a)(2)(ii) of Form 20-F.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Celulosa Arauco y Constitución S.A.

We have audited the accompanying consolidated statements of financial position of Celulosa Arauco y Constitución S.A. and subsidiaries (the “Company”) as of December 31, 2012, and the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for the year then ended. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Celulosa Arauco y Constitución S.A. and subsidiaries as of December 31, 2012, and the results of their operations and their cash flows for the year then ended in conformity with International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (“IASB”).

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

F-7

Period covered by the Financial Statements

As of December 31, 2012 and 2011 and for the years ended December 31, 2012, 2011 and 2010

Date of Approval of Financial Statements

These consolidated financial statements were authorized and approved for issue by the Board of Directors of the Company (the “Board”) at the Extraordinary Session N° 482 held on March 8, 2013.

Functional and Presentation Currency

Arauco and most of its subsidiaries has determined the U.S. Dollar as its functional currency since majority of its revenues from sales of its products are from exports, while its costs of sales are to a large extent related or index to the U.S. Dollar.

For the pulp operating segment, most of the sales are exports, and the costs are related mainly to plantation costs, which are settled in U.S. Dollars.

For the sawmill, panel and forestry operating segments, although total sales include a mix of domestic and exports sales, the prices for the products are established in U.S. Dollars, as is also the case for the cost structure of the related raw materials.

In relation to cost of sales, although the costs of labor and services are generally billed and paid in local currency, these costs are not as significant as the costs of raw materials, which are driven mainly by global markets and therefore, influenced mostly by the U.S. Dollar.

The presentation currency of the consolidated financial statements is the U.S. dollar.

Figures on these consolidated financial statements are presented in thousands of U.S. dollar (ThUS$).

Additional Information Relevant to the Understanding of the Financial Statements

The company Fondo de Inversión Bío Bío and its subsidiary Forestal Río Grande S.A. meet the requirements for classification as Special Purpose Entities. These entities are in substance controlled by Arauco, which is indicated, by the existence of exclusive contracts with Arauco for wood supply, future purchases of land and forest administration. Consequently, the financial statements of these companies are included in the consolidated financial statements of Arauco.

Compliance and adoption of IFRS

The accompanying consolidated financial statements of Arauco presents in all material respects its financial position, its results of operations and its cash flows in accordance with IFRS as issued by the IASB.

This presentation is required to give a faithful representation of the effects of transactions, as well as other events and conditions, according to the definitions and criteria established within the conceptual framework of IFRS for the recognition of assets, liabilities, income and expenses.

F-8

Summary of significant accounting policies

The accompanying consolidated financial statements as of December 31, 2012 were prepared in accordance with Arauco’s accounting policies, which have been consistently applied to all periods presented in these consolidated financial statements.

a) Basis for Presentation of financial statements

The accompanying consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and they represent the integral, explicit and unreserved adoption of IFRS.

The consolidated financial statements have been prepared on the historical cost basis except for biological assets, and certain financial assets and financial liabilities (including derivative instruments) that are measured at fair value.

b) Critical accounting estimates and judgments

The preparation of consolidated financial statements in accordance with IFRS requires management to make estimates and assumptions that affect the carrying amounts reported. The estimates are based on historical experience and various other assumptions that are considered to be reasonable. Actual results may differ from these estimates. Management believes that the accounting policies below are the critical judgments that have the most significant effect on the amounts recognized in the consolidated financial statements.

- Property, Plant and Equipment

In a business acquisition, management values the acquired property, plant and equipment and their useful lives in consultation with a third party expert.

The carrying amounts of property, plant and equipment are reviewed whenever events or changes in circumstances indicate that the carrying amount of an asset may be impaired. The recoverable amount of an asset is the higher of fair value less costs to sell and its value in use, with an impairment loss recognized whenever the carrying amount exceeds the recoverable amount. The value in use is calculated using a discounted cash flow model, which is most sensitive to the discount rate as well as the expected future cash inflows.

A sensitivity analysis related to the estimated useful lives is disclosed in Note 7.

- Fair Value of Financial Instruments

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. Arauco uses its judgment to select a variety of methods and makes assumptions that are mainly based on market conditions existing at each reporting date.

Detailed financial information about the fair value of financial instruments and sensitivity analysis are presented in Note 23.

F-9

-Biological Assets

The recovery of forest plantations is based on discounted cash flow models which mean that the fair value of biological assets is calculated using cash flows from continuing operations on a discounted basis, on our sustainable forest management plans and the estimated growth of forests.

These discounted cash flows require estimates in growth, harvest, sales prices and costs. It is therefore important that management make appropriate estimates of future levels and trends for sales and costs, as well as conduct regular surveys of the forests to establish the volumes of wood available for harvesting and their current growth rates. The main considerations used to measure forest plantations are presented in Note 20, including a sensitivity analysis.

-Impairment of goodwill

Determining whether goodwill is impaired requires an estimation of the value in use of the cash-generating units to which goodwill has been allocated. The value in use calculation requires the directors to estimate the future cash flows expected to arise from the cash-generating unit and suitable discount rate in order to calculate present value.

-Employee benefits

The cost of defined employee benefits for termination of employment, as well as the present value of the obligation is determined using actuarial valuations. The actuarial valuations involve making assumptions about discount rates, staff turnover, future salary increases and mortality rates.

- Litigations and Contingencies

Arauco and its subsidiaries are subject to certain litigations. Future effects on Arauco’s financial condition resulting from these litigations are estimated by management, in collaboration with its legal advisors. Arauco recognizes provisions on each statement of financial position date and/or upon each substantial modification to an underlying claim of any such litigations. For description of current litigations see Note 18.

c) Consolidation

The consolidated financial statements include all entities over which Arauco has the power to govern the financial and operating policies, which is presumed to exist when Arauco holds more than one half of the voting rights of an entity so as to obtain benefits from its activities. Subsidiaries (including special purpose entities) are consolidated from the date on which control is transferred to the group and up to the date that control ceases.

A special purpose entity (“SPE”), is an organization that is established for a specific purpose or limited duration. Often these SPE, serve as intermediary organizations. In substance, the activities of the SPE are being conducted on behalf of Arauco according to its specific business needs so that it obtains benefits from the SPE’s operation. An SPE shall be consolidated when the substance of the relationship between the consolidated entity and the SPE indicates that it is controlled by that entity.

All intercompany transactions and unrealized gains and losses from subsidiaries and special purpose entities have been fully eliminated from consolidation and non-controlling interests is presented in the consolidated statement of financial position within equity, separately from the equity of the owners of the parent.

F-10

The consolidated financial statements as of December 31, 2012 and 2011 include the assets, liabilities, income and expenses of the subsidiaries shown in Note 13 and those of the Fondo de Inversión Bío Bío, and its subsidiary Forestal Río Grande S.A., both of which are Special Purpose Entities.

Certain consolidated subsidiaries have Brazilian Real and Chilean Pesos as, their functional currencies. For consolidation purposes, the financial statements of those subsidiaries have been prepared in accordance with IFRS and translated into the presentation currency as indicated in Note 1 (e) (ii).

Accounting policies for subsidiaries are adjusted if necessary to ensure consistency with the accounting policies applied by Arauco.

d) Segments

Arauco has defined its operating segments according to its business areas, based on the products and services sold to its customers. This definition is consistent with the management, resource allocation and performance assessment made by key personnel responsible for making relevant decisions related to the Company’s operation. The Chief Operating Decision Maker (CODM) is the Chief Executive Officer who is responsible for making these decisions and it is supported by the Corporate Managing Directors of each segment.

In line with the above, the Company established operating segments according to the following business units:

• Pulp

• Panels

• Sawn Timber

• Forestry

Refer to Note 24 for detailed financial information by operating segment.

e) Functional currency

(i) Functional currency

All items in the financial statements of Arauco and each of its subsidiaries, associates and jointly controlled entities are measured using the currency of the primary economic environment in which each entity operates (the functional currency). The consolidated financial statements are presented in U.S. dollars, which is Arauco’s functional and presentation currency.

(ii) Translation to the presentation currency of Arauco

For the purposes of presenting consolidated financial statements, the assets and liabilities of Arauco’s foreign operations are translation into U.S. dollars using exchange rates prevailing at the end of each reporting period. Income and expense items are translated at the average exchange rates for the period, unless exchange rates fluctuate significantly during that period, in which case the exchange rates at the dates of the transactions are used. Exchange differences arising, if any, are recognized in other comprehensive income and accumulated in equity.

F-11

On the disposal of a foreign operation, all of the exchange differences accumulated in equity in respect of that operation attributable to the owners of the parent are reclassified to profit or loss. In addition, in relation to a partial disposal of a subsidiary that does not result in Arauco losing control over the subsidiary, the proportionate share of accumulated exchange differences are re-attributed to non-controlling interests and are not recognized in profit or loss. For partial disposals of associates or jointly controlled entities that do not result in Arauco losing significant influence or joint control, the proportionate share of the accumulated exchange differences is reclassified to profit or loss.

Goodwill and fair value adjustments on identifiable assets and liabilities acquired arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and translated at the exchange rate prevailing at the end of each reporting period. Exchange difference arising are recognized in other comprehensive income and accumulated in equity.

(iii) Foreign Currency Transactions

Transactions in foreign currencies are recognized at the exchange rates prevailing at the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are retranslated at the rates prevailing at that date. Non-monetary items carried at fair value that are denominated in foreign currencies are retranslated at the rates prevailing at the date when the fair value was determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated.

Exchange differences on monetary items are recognized in profit or loss in the periods in which they arise except for exchange differences on transactions entered into in order to hedge certain foreign currency risks.

f) Cash and cash equivalents

Cash and cash equivalents include cash-in-hand, deposits held on demand at banks and other short term highly liquid investments with an original maturity of less than three months and which are subject to an insignificant risk of changes in value.

g) Financial Instruments

(i) Financial assets and liabilities measured at fair value through profit or loss

Financial assets measured at fair value through profit or loss are financial assets held for trading. A financial asset is classified in this category if it is acquired principally for the purpose of selling it in the short term.

Derivatives are also classified as held for trading unless they are designated and effective as hedging instruments. Assets in this category are classified as current assets and the obligation for these instruments is presented under other financial liabilities within the statement of financial position.

Regular purchases and sales of financial assets are recognized on the trade date, which is the date on which Arauco commits itself to purchase or sell the asset.

The financial assets and liabilities measured at fair value through profit or loss are initially recognized at fair value and transaction costs are expensed in the statement of income. They are subsequently measured at fair value with any gains or losses from changes in fair value recognized in profit or loss.

F-12

Interest Rate and Currency Swaps: Swaps are measured using the discounted cash flow method at a discount rate consistent with the risk of the operation.

Foreign Exchange Forwards: These instruments are initially recognized at fair value at the date on which the contract is entered into and are subsequently remeasured at fair value. Forwards are recognized as assets when fair value is positive and, as liabilities when fair value is negative.

The fair value of foreign exchange forward contracts is calculated by reference to current forward exchange rates for contracts with similar maturities.

The fair value of interest rate forward contracts is calculated by reference to the difference of the existing interest rates between the interest rate contractually agreed and the market interest rate at the end of each reporting period.

Mutual Funds: They are highly liquid instruments that are sold in the short term and are carried at their net asset value at the end of each period.

(ii) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and receivables are classified as current assets, except for those with maturities more than 12 months after the reporting period, which are classified as non-current assets. Loans and receivables include trade and other receivables.

Loans and receivables are initially recognized at fair value and subsequently are measured at amortized cost using the effective interest rate method, less any impairment.

Repurchase Agreements: These are recognized at their initial investment cost plus accrued interest at the end of each reporting period. These contracts have maturities of less than 30 days.

(iii) Financial liabilities measured at amortized cost

Bank borrowings, debt issued (bonds) and financial liabilities of a similar nature are initially recognized at fair value. Transactions costs are included in the carrying amount of the liabilities and are amortized over the lives of the liabilities using the effective interest rate method).

In subsequent periods, they are measured at amortized cost and any difference between the proceeds (net of transaction costs) received, and the redemption value is recognized in profit or loss statement over the life of the debt using the effective interest rate method.

Financial liabilities are classified as current liabilities unless the Company has an unconditional right to defer settlement for at least twelve months after the reporting period.

The fair value of bank borrowings is determined using discounted cash flow techniques using rates consistent with the risk associated with bank borrowings of similar nature, while bonds are measured at their quoted market price.

F-13

(iv) Trade and other payables

These instruments are initially recognized at fair value and subsequently are measured at amortized cost using the effective interest rate method.

(v) Hedging instruments

The effective portion of changes in the fair value of derivatives that are designated and qualify as hedging instruments in cash flow hedges is recognized in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the statement of income within other income or other expenses, respectively.

When a hedging instrument expires or is settled, or when it ceases to qualify for hedge accounting, any cumulative gain or loss recognized in equity remains in equity until the forecasted transaction occurs, when the transaction occurs it is reclassified to profit or loss. When a forecasted transaction is no longer expected to occur, the cumulative gain or loss recognized in equity is immediately reclassified to profit or loss.

The fair value of hedging instruments are measured using internal model including discounted cash flow techniques that use a discount rate consistent with the operational risk using internal valuation methodology and market information from providers of recognized reputation.

h) Inventories

Inventories are stated at the lower of cost and net realizable value. Cost is determined using the weighted average cost method.

The cost of finished goods and products in process includes the cost of raw materials, direct labor, other direct costs and general overhead expenses, excluding interest expenses.

Initial costs of harvested wood are determined at fair value less cost of sale at the point of harvest.

Biological assets are transferred to inventories when forests are harvested.

Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

When market conditions result in the production costs of a product exceeding its net realizable value, the inventories are write-down to its net realizable value. This write-down also includes obsolescence amounts resulting from slow moving inventories and technical obsolescence.

Spare parts that will be consumed in a period of less than twelve months, are presented in inventories and recognized as an expense when they are consumed.

i) Non-current assets held for sale

Non-current assets held for sale are measured at the lower of their previous carrying value and fair value less costs to sell. Assets are classified as held for sale when their carrying value will be recovered principally through a sale transaction that is highly probable and the non-current asset is available for immediate sale in its present condition. Management must be committed to a plan to sell the asset, and an active program to locate a buyer and complete the plan must have been initiated. In addition, the sale should be expected to

F-14

qualify for recognition as a completed sale within one year from the date of classification, except for the existence of events or circumstances (beyond the entity’s control) that may extend the period to complete the sale beyond one year.

Non-current assets classified as held for sale are not depreciated.

j) Business Combinations

Arauco applies the acquisition method to account for a business combination. This method, requires to identify the acquirer, determine the acquisition date, recognize and measure the identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree; and recognize and measure goodwill or a gain from a bargain purchase. Identifiable assets acquired and liabilities assumed and any contingent liabilities in a business combination are initially measured at fair value at the acquisition date.

Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree, and the fair value of the acquirer’s previously held equity interest in the acquiree (if any) over the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. If the total of consideration transferred, non-controlling interest recognized and previously held interest measured is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For purposes of impairment testing, goodwill in a business combination is allocated as of the acquisition date to the cash generating unit of the group or groups of cash generating units expected to benefit from the synergies of the combination irrespective of whether other assets or liabilities of the acquire are allocated to those units or groups of units.

Acquisition-related costs are accounted for as expenses when they are incurred, except for costs to issue debt or equity securities which are recognized in accordance with IAS 32 and IAS 39.

Non-controlling interests that are present ownership interests and entitle their holders to a proportionate share of the entity’s net assets in the event of liquidation may be initially measured either at fair value or at the present ownership instruments’ proportionate share in the recognized amounts of the acquire’s identifiable net assets. The choice is made on a transaction-by-transaction basis.

Arauco measures the fair value of the acquired company in the business combination on a step by step basis, recognizing the effects of variation in the income statement.

If the initial accounting for a business combination is not completed by the end of the reporting period in which the combination occurs, Arauco reports provisional amounts for the items for which the accounting is incomplete. During the measurement period (no more than one year), these provisional amounts are retrospectively adjusted, or additional assets or liabilities are recognized to reflect new information about facts and circumstances that existed at the acquisition date, if known, would have affected the amounts recognized at that date.

k) Investments in associates and joint ventures

Associates are entities over which Arauco exercises significant influence, generally when it holds between 20% and 50% of the voting rights, but not control.

F-15

Joint venture is defined as an entity over which there is joint control, which exists only when the decisions about strategic of activities, both financial and operational, require the unanimous consent of the parties sharing control.

Investments in associates and joint ventures are accounted for using the equity method and are initially recognized at cost. Their carrying amount is increased or decreased to recognize Arauco’s share of the profit or loss and other comprehensive income (exchange differences on translation to the reporting currency) of the associate or joint venture. Dividends received are recognized by deducting the carrying amount of the investment. Arauco’s investment in associates includes goodwill (net of any accumulated impairment loss).

If the total of consideration transferred, non-controlling interest recognized and previously held interest measured is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the income statement.

These investments are presented in the consolidated statement of financial position in the line item “Investments accounted for using equity method”.

If Arauco’s share of losses of an associate or joint venture equals or exceeds its interest in the associate or joint venture, Arauco discontinues recognizing its share of further losses. After Arauco’s carrying value in the investee is reduced to zero, additional losses are provided for, and a liability is recognized, only to the extent that Arauco has incurred legal or constructive obligations or made payments on behalf of the associate or joint venture. If the associate or joint venture subsequently reports profits, Arauco resumes recognizing its share of those profits only after its share of the profits equals the share of losses not recognized.

l) Intangible assets

After initial recognition, intangible assets are with finite useful lives carried at cost less any accumulated amortization and impairment losses.

Amortization of an intangible asset with a finite useful life is allocated on a systematic basis over the asset’s useful life. Amortization begins when the asset is available for use, i.e. when it is in the location and condition necessary for it to be capable of operating in the manner intended by management

(i) Computer Software

Computer software licenses are capitalized in terms of the costs incurred to acquire them and make them compatible with existing software. These costs are amortized over the estimated useful lives.

(ii) Water Rights, Easements and Other Rights

This item includes water-rights, easements and other acquired rights recognized at historical cost which have indefinite useful lives as there is no foreseeable limit to the period over which these assets are expected to generate net cash inflows. These rights are not amortized, but are tested for impairment at least annually, or when there is any indication that the assets might be impaired.

m) Goodwill

Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree, and the fair value of the acquirer’s

F-16

previously held equity interest in the acquiree (if any) over the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. Goodwill is not amortized but is tested for impairment on annual basis.

Goodwill recognized for the acquisition of the subsidiary Arauco do Brasil S.A. whose functional currency is the Brazilian real, is translated into U.S. dollars at the closing exchange rate. At the date of these financial statements, the only change in the carrying amount of goodwill is related to the net exchange rate differences on translation.

n) Property, Plant and Equipment

Property, plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. The cost includes expenditures that are directly attributable to the acquisition of the assets.

Subsequent costs, such as improvements and replacement of components, are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to Arauco and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized from property, plant and equipment. All other repairs and maintenance costs are expensed in the period in which they are incurred.

Arauco capitalizes borrowing costs that are directly attributable to the acquisition, construction or production of qualifying assets as part of the cost of those assets, until the assets are ready for their intended use (see Note 12).

Depreciation is calculated by components using the straight-line method.

The useful lives of the items of property, plant and equipment is estimated according to the expected use of the assets.

The residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period.

o) Leases

Leases of assets in which Arauco substantially holds all the risks and rewards of ownership are classified as finance leases. Finance leases are initially recognized at the lower of the fair value at the inception of the lease of the leased property and the present value of the minimum lease payments.

When assets are leased under a finance lease, the present value of lease payments are recognized as financial account receivables. Finance income, which is the difference between the gross receivable and the present value of such amount, is recognized as the interest rate of return.

Leases in which substantially all risks and rewards are not transferred to the lessee are classified as operating leases. Payments under operating leases (net of any incentives received from the lessor) are recognized as an expense on a straight-line basis over the lease term.

p) Biological Assets

IAS 41 requires that biological assets, such as standing trees, are measured at fair value in the statement of financial position. Plantations forestry are accounted for at fair value less costs to sell, based on the presumption that fair values of these assets can be measured reliably.

F-17

The measurement of plantations forestry is based on discounted cash flow models whereby the fair value of the biological assets is determined using estimated future cash flows from continuing operations calculated using our sustainable forest management plans and including the estimated growth of the forests. This valuation is performed on the basis of each identifiable farm block and for each type of tree.

The measurement of new plantations forestry made during the current year, is made at cost, which corresponds to the fair value at that date. After twelve months, the valuation methodology used is that explained in the preceding paragraph.

Biological assets shown as current assets correspond to those plantations forestry that will be harvested in the short term.

Biological growth and changes in fair value of plantations forestry are recognized in line item other income included in profit from operating activities in the statement of income.

The Company holds fire insurance policies for its plantations forestry, which together with company resources and efficient protection measures for these plantations assets allow financial and operational risks to be minimized.

q) Income taxes and Deferred taxes

The tax liabilities are recognized in the financial statements based on the determination of taxable income for the year and calculated using the tax rates in force in the countries where Arauco operates.

Deferred income tax is recognized using the balance sheet liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted by the end of the reporting period and that are expected to apply when the related deferred tax asset is realized or the deferred income tax liability is settled.

The goodwill arising on business combinations not give rise to deferred tax.

The deferred tax assets are generally recognized for all deductible temporary differences to the extent that it is probable that future taxable profit will be available against which those deductible temporary differences can be utilized.

r) Provisions

Provisions are recognized when the Company has a present obligation, legal or constructive, as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period.

s) Revenue recognition

Revenues are recognized when Arauco has transferred the risks and rewards of ownership to the buyer and Arauco retains neither continuing managerial involvement to the degree

F-18

usually associated with ownership nor effective control over the goods sold. This means that generally revenues are recorded upon delivery of goods to customers in accordance with the agreed terms of delivery.

(i) Revenue recognition from the Sale of Goods

Revenue from the sale of goods is recognized when Arauco has transferred to the buyer the significant risks and rewards of ownership of the goods, when the amount of revenue can be reliably measured, when Arauco does not retain any managerial involvement over the goods sold and when it is probable that the economic benefits associated with the transaction will flow to Arauco and the costs incurred in respect of the transaction can be measured reliably.

Sales are recognized in terms of the price agreed to in the sales contract, less any volume discounts and estimated product returns at the date of the sale. Volume discounts are evaluated in terms of estimated annual purchases. There is no significant financing component given that receivables from sales are collected within a short period, which is in line with market practices.

(ii) Revenue recognition from Rendering of Services

When the outcome of a transaction involving the rendering of services can be estimated reliably revenue associated with the transaction is recognized by reference to the stage of completion of the transaction at the date of the reporting period, and when it is probable that the economic benefits associated with the transaction will flow to the Arauco.

Arauco, mainly provides power supply which are traded in the spot market of the Sistema Interconectado Central (Interconnected Central System). According to current regulations, the prices on that market called “Marginal Costs” are calculated by the Centro de Despacho Económico de Carga del Sistema Interconectado Central (CDEC-SIC) (Load Economical Dispatch Center of the Interconnected Central System) and are generally recognized in the period in which the services are rendered.

Electrical power is generated as a by-product of the pulp process and is a complementary business to it, which is firstly supplied to the group’s subsidiaries and any surplus is sold to the interconnected central system.

Arauco provides other non-core services such as port services and pest control whose revenues are derived from fixed price service contracts, generally recognized during the period of the service contract on a straight-line basis over the term of the contract.

Revenues from operating segments mentioned in Note 24 are measured in accordance with the policies indicated in the preceding paragraphs.

Revenues from inter-segment sales (which are made at market prices) are eliminated in the consolidated financial statements.

t) Minimum dividend

Article No. 79 of the Chilean Corporations Law states that, unless otherwise unanimously agreed by the shareholders, corporations must distributed annually at least 30% of net income for the current year as cash dividend to shareholders determined in proportion to their shares or in the proportion established in the by-laws for preferred shares, if any, except where necessary to absorb accumulated losses from prior years.

F-19

The General Shareholders’ Meeting of Arauco agreed to distribute annual dividends at 40% of net distributable income, including an interim dividend to be distributed at year end. Dividends payable are recognized as a liability in the financial statements in the period when they are declared and approved by the Arauco’s shareholders or when arises the corresponding present obligation based on existing legislation or distribution policies established by the Shareholders’ Meeting.

The interim and final dividends are recorded in equity upon their approval by the Company’s Board of Directors and the shareholders.

Dividends payable are presented in the line item “other current non financial liabilities”.

Dividends paid are not deductible for income tax purposes.

u) Impairment

Non-financial Assets

The recoverable amount of property, plant and equipment and other assets with finite useful lives are measured whenever there is any indication that the assets have suffered an impairment loss. Among the indications to consider as evidence of impairment are significant declines in the assets’ market value, significant adverse changes in the technological environment, obsolescence or physical damages of assets and changes in the manner in which the asset is used or expected to be used). Arauco evaluates at the end of each reporting period whether there is any evidence of the indications above mentioned.

For this evaluation, assets are grouped at the lowest level of group of assets that generates cash flows independently.

Goodwill and intangible assets with indefinite useful life are tested annually for impairment or whenever circumstances indicate it. The recoverable amount of an intangible asset is the higher of its fair value less costs of disposal and its value in use. An impairment loss is recognized whenever the carrying amount exceeds the recoverable amount.

A cash-generating unit to which goodwill has been allocated is tested for impairment annually, or more frequently when there is an indication that the unit may be impaired. If the recoverable amount of the cash-generating unit is less than its carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro rata based on the carrying amount of each asset in the unit. Any impairment loss for goodwill is recognized directly in profit or loss. An impairment loss recognized for goodwill is not reversed in subsequent periods.

A previously recognized impairment loss is reversed if, and only if, there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. Impairment losses are reversed so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset in prior years. An impairment loss recognized for goodwill is not reversed in subsequent periods.

For the purposes of assessing impairment losses, assets are grouped at the lowest level for which there is identifiable cash flows separately for each cash-generating unit. Non-financial assets, other than goodwill, which had suffered an impairment loss, are reviewed at the end of each reporting period whether there is any indication that an impairment loss previously recognized may no longer exists or have decreased.

F-20

“Cash-generating units” are the smallest identifiable groups of those cash inflows that are largely independent of the cash inflow from other assets or groups of assets.

Goodwill is allocated to cash-generating units for impairment testing purposes. The allocation is made between cash-generating units or groups of cash generating units expected to benefit from the synergies of the combination.

Financial Assets

At the end of each reporting period, an evaluation is performed in order to identify whether there is any objective evidence that a financial asset or a group of financial assets may have been impaired. Financial assets are impaired only when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of a financial asset, the estimated future cash flows of the financial asset have been affected. Impairment losses are recognized in the consolidated statement of income.

The allowance for doubtful accounts is established when there is objective evidence that Arauco will not receive payments under the original sale terms. Allowance is made when the customer is a party to a bankruptcy court agreement or cessation of payments, and are written-off when Arauco has exhausted all levels of recovery of the receivable in a reasonable time.

The allowance for doubtful accounts is measured as the difference between the carrying amount of receivables and the present value of estimated future cash flows. The carrying amount of the receivable is reduced through the use of the allowance. If the impairment loss decreases in later periods, it is reversed either directly or by adjusting the provision for doubtful accounts, with effect in profit or loss.

v) Employee Benefits

Arauco has severance payment obligations arising from voluntary termination of employment. These are paid to certain employees that have been employed by the company for more than five years in accordance with conditions established within collective or individual employment contracts.

This is an estimate of the years of service-based severance payments to be recognized as a future termination payment liability, in accordance with contracts between Arauco and its employees and pursuant to actuarial valuation criteria for this type of liability. These obligations are considered a defined benefit plan.

The main factors considered for calculating the actuarial value of severance payments obligation for years of service are the employee turnover, salary increases and life expectancy of the workers included in this benefit.

Actuarial gains and losses are recognized in profit or loss in the year they are incurred.

These obligations are treated as post-employment benefits.

w) Employee Vacations

Arauco recognizes the expense for employee vacation according to labor legislation in each country on an accrual basis.

This obligation is presented in the line item “Trade and Other payables” in the consolidated statement of financial position.

In order to recognize inventories at net realizable value, at December 31, 2012, a reversal of an obsolescence allowance was recorded in the amount of ThU.S.$4,749 (the provision increased by ThU.S.$2,957 as of December 31, 2011), and an increased provision was recorded in both years for damaged inventory, ThU.S.$20,834 and ThU.S.$313 as of December 31, 2012 and 2011, respectively as result of the fire occurred in January 2012 affecting a panels plant in Complejo Forestal e Industrial Nueva Aldea.

The allowance of obsolescence is calculated based on the conditions of sale of products and age of inventory (inventory turnover).

No inventories have been pledged as security for liabilities at the end of each reporting period.

Agricultural Products

Agricultural Products are mainly forestry products that are intended for sale in the normal course of our operations and are measured at fair value less costs to sell at the point of harvest at the end of each reporting period Agricultural products are classified as raw materials within the line item inventories.

NOTE 4. CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash on hand, bank checking account balances, time deposits, repurchase agreements and mutual funds. They are short-term highly liquid investments that are readily convertible to known amounts of cash, and are subject to an insignificant risk of changes in value.

The investment objective of time deposits and repurchase agreements is to maximize in the short-term the amounts of cash surpluses. These instruments are permitted under Arauco’s Investment Policy, which allows investing in fixed income securities. These instruments have a maturity of less than three months from the date of acquisition.

Arauco invests in local and international mutual funds in order to maximize the returns of cash surpluses denominated in Chilean Pesos or in foreign currencies such as U.S. Dollars or Euros. These instruments are permitted under Arauco’s Investment Policy.

As of the date of these consolidated financial statements, there are no amounts of cash and cash equivalents with restrictions on use.

NOTE 5. ACCOUNTING POLICIES, CHANGES IN ACCOUNTING ESTIMATES AND ERRORS

Changes in Accounting Policies

The accounting policies have been developed in accordance with the effective IFRS as of December 31, 2012 and have been consistently applied to all periods presented in these consolidated financial statements.

Changes in Estimates and Accounting Policies

The financial statements as of December 31, 2012 do not show changes in accounting policies compared to the last year.

Errors

The financial statements as of December 31 2011 have been revised to reflect the effects of the following error corrections:

a) The recognition of certain lease contracts as finance leases that were previously accounted for as operating, as a result, the line items “property, plant and equipment” and “other non-current liabilities” increase of ThU.S.$69,806 as of December 31, 2011 (ThU.S.$38,874 as of January 1, 2011).

For purposes of Income statements, this item operation was initially classified as rental expense within cost of sales, and is now classified as “depreciation expense” within cost of sales situation that does not modify the presentation on purpose of increase of “Property, plant and equipment”. This revision had no impact on the statement of cash flows.

b) The presentation of hedging derivative contracts were recorded net of derivative asset and derivative liability, involved an increase of ThU.S.$24,650 as of December 31, 2011 in the line items Other non-current financial assets and other non-current liabilities. As of January 1, 2011, the Group did not enter into any hedging derivative contracts, thus no reclassification was required.

F-30

The effects of the corrections are not material, and over the total assets and liabilities as of December 31, 2011 and January 1, 2011, were as follows:

	Previously reported
	balances		Adjustment		As revised
	to 12-31-2011		filing		to 12-31-2011
	ThU.S.$		ThU.S.$		ThU.S.$
Total assets		12,457,722		94,456		12,552,178
Total liabilities		5,427,572		94,456		5,522,028

Total liabilities		5,665,757		38,874		5,704,631

These error corrections had neither effect in profit or loss nor in equity.

c) A revision was also in the presentation of port services from Cost of sales to Distribution costs in the amount of ThU.S.$ 27,499 at December 31, 2011 (ThU.S.$ 21,745 at January 1, 2011).

The above effects are not significant and do not alter the profit or loss.

NOTE 6. TAXES

The tax rates applicable in the countries in which Arauco operates are 20% in Chile, 35% in Argentina, 34% in Brazil and 34% in United States (federal tax).

On July 30, 2010, Law No. 20,455 for National Reconstruction Financing was published in the Chilean Official Gazette (Diario Oficial de Chile). One of the most important changes under the law was the temporary increase in tax rates to 20% and 18.5% during fiscal years 2011 and 2012, respectively, to ease back to a tax rate of 17% in fiscal year 2013.

On September 27, 2012, Law N° 20,630 was enacted in Chile, and among other changes, it increases the tax rate to a permanent 20%, effective beginning on tax year 2012. The change in the tax rate in 2012 affected the measurement of the tax consequences of temporary differences that are expected to reverse in the corresponding tax years.

The effect on the results of operations for the year ended December 31, 2012 due to the change in tax rate was an expense of ThU.S.$128,981, which was mainly the result of the expected reversal of temporary differences associated with property, plant, equipment and biological assets.

F-31

Deferred Tax Assets

The following table sets forth the deferred tax assets as of December 31, 2012 and 2011:

	12-31-2012		12-31-2011
Deferred Tax Assets	ThU.S.$		ThU.S.$
Deferred tax Assets relating to Provisions		4,752		7,878
Deferred tax Assets relating to accrued liabilities		6,385		4,766
Deferred tax Assets relating to Post-Employment benefits		9,341		6,625
Deferred tax Assets relating to Property, Plant and equipment		10,822		11,545
Deferred tax Assets relating to Financial Instruments		297		789
Deferred tax Assets relating to tax losses carryforwards		90,327		71,870

Deferred tax assets relating to provisions for income		4,477		4,064
Deferred tax assets relating to provision for doubtful accounts		3,602		4,458
Deferred tax assets relating to other deductible temporary differences		19,958		15,108
Total deferred tax assets		161,739		135,890

As of December 31, 2012, certain of Arauco’s subsidiaries have carryforwards tax losses of ThU.S.$ 342,044 (ThU.S.$ 343,311 as of December 31, 2011) which are mainly generated due to operational and financial losses. Arauco believes that it is probable that future taxable profits will be available in the subsidiaries against which the unused tax losses will be utilized.

Deferred Tax Liabilities

The following table sets for the deferred tax liabilities as of December 31, 2012 and 2011:

	12-31-2012		12-31-2011
Deferred Tax Liabilities	ThU.S.$		ThU.S.$
Deferred tax liabilities relating to property, Plant and equipment		736,530		747,450
Deferred tax liabilities relating to financial instruments		14,218		3,723
Deferred tax liabilities relating to biological assets		531,801		426,250
Deferred tax liabilities relating to inventory		16,517		14,509
Deferred tax liabilities due to prepaid expenses		55,294		41,487
Deferred tax liabilities relating to other taxable temporary differences		41,294		22,814
Total deferred tax liabilities		1,395,654		1,256,233

The effect of changes in deferred tax liabilities related to cash flow hedges corresponds to a credit of ThU.S.$4,823 as of December 31, 2012 (credit of ThU.S.$932 as of December 31, 2011), which is presented deducting the reserve of cash flow hedges in the statement of changes in equity.

The deferred tax assets and liabilities expected to be recovered and settled in less than twelve months amounts to ThU.S.$23,638 and ThU.S.$126,410, respectively.

Arauco does not offset deferred tax assets and deferred tax liabilities since there is no legal enforceable right to offset amounts recognized in these items that relate to different tax jurisdictions.

Description of Property, Plant and Equipment Pledged as Security for Liabilities

In October 2006, Forestal Río Grande S.A, a subsidiary of Fondo de Inversión Bío Bío (Arauco’s special purpose entity), executed in favor of JPMorgan Chase Bank N.A. and Arauco, respectively, first and second degree mortgages, which prohibited the sale of any property owned by Fondo de Inversión Bío Bío in order to secure its obligations.

In September 2007, Forestal Río Grande S.A acquired a real estate in Yungay, located in Chile’s Eighth Region, for which the company executed a first and second degree mortgage in favor of JPMorgan and Arauco, respectively, which prohibited the sale and encumber such property.

The Group made the initial accounting for the acquisition of the Flakeboard based on provisional amounts. The provisional amounts of assets acquired and liabilities assumed might be adjusted during the measurement period (which shall not exceed one year from the acquisition date) to reflect new information obtained about facts and circumstances existing as of the acquisition date and, if known, would have affected the measurement of the amounts recognized as of that date.

NOTE 16. INTERESTS IN JOINT VENTURES

Investments and contributions made

In March 2012 Arauco do Brasil S.A. (a subsidiary) made a capital contribution to Unilin Arauco Pisos Ltda. ( formerly Arauco Pisos Laminados S.A.) in the form of assets for a total of ThR$24,990 (ThU.S.$12,235) for the flooring line of the Pien location (Paraná Brasil), no gain or loss was recognized on this contribution. In April 2012, Arauco sold a 50% interest of Unilin Arauco Pisos Ltda. to Mohwak Unilin International B.V. for ThR$12,500 (ThU.S.$6,120 at December 31, 2012), becoming a joint venture. The sale price for this transaction was equivalent to its carrying amount, thus had no effect on profit or loss. This company is engaged in manufacturing, processing, industrialization and selling of wood laminate floors.

As of December 31, 2012, Arauco, through its subsidiary Arauco Holanda Cooperatief U.A, made capital contributions for a total of ThU.S.$145,977 (ThU.S.$177,397 as of December 31, 2011) to two Uruguayan joint ventures, Celulosa y Energía Punta Pereira S.A. and Zona Franca Punta Pereira S.A., with Arauco holding 50% ownership interest in the joint venture. This transaction had no effect on results.

Celulosa y Energia Punta Pereira S.A. and Zona Franca Punta Pereira S.A. are both involved in the project known as “Montes del Plata”, which purpose is to build a cutting edge cellulose production plant, with a capacity of 1.3 million tons per year, a port and an energy generation unit utilizing renewable resources, which will be located at the town of Punta Pereira, Province of Colonia, Uruguay.

At the date of these financial statements, Arauco has committed contribution to Montes del Plata for ThU.S.$66,094.

Investments in Uruguay

The main assets acquired from former owner Grupo Empresarial Ence (Spanish company) during the year 2009 are: 130,000 hectares of land of which 73,000 hectares are forestry plantations; 6,000 hectares under agreements with third parties; one industrial site, the necessary environmental permits for the construction of a pulp mill; a river terminal; one chip producing mill, and one forest nursery.

All these assets were added to the land and plantations that Stora Enso and Arauco already control through a joint venture in Uruguay. With these additions, the joint venture currently maintains ownership interest in forestry area of approximately 270 thousand hectares of land, of which 156 thousand hectares are planted.

Investments in Uruguay are joint ventures because of existing contracts that stipulate that both Arauco and Stora Enso maintain joint control of such investments, each holding a 50% stake.

Furthermore, Arauco holds a 50% in Eka Chile S.A. (“Eka”), a company that sells sodium chlorate to cellulose plants in Chile. A contractual agreement in effect between Arauco and Eka has permitted Arauco and Eka to initiate certain joint venture activities.

NOTE 17. IMPAIRMENT OF ASSETS

Effects from the economic crisis

Since the beginning of 2009, the complicated market condition affected the Bosseti sawmill operation located in Argentina and the Company decided to shut it down in December 2010 and to adapt its operational structure to the reality of the business, converting the operation and using its land and buildings as a logistics center. As of December 31, 2010, the Company recognized ThU.S.$2,000 in impairment losses to machinery and equipment, which at December 31, 2012, after impairment loss, have a carrying value of ThU.S.$1,000 (ThU.S.$1,600 as of December 31, 2011). At the end of the reporting period, some machinery and equipment were sold, others were moved to sawmill located in Piray and the remaining machinery and equipment are being organized and prepared for subsequent sale.

The recoverable amount of the permanently closed facilities was determined based on estimates of the sale proceeds and residual value, making the corresponding provision in the event that the recoverable amount is less than the carrying amount. These estimates were made by both external and internal evaluators.

Effects of forestry fire

The amount of the existing provision is referred to assets that are in the process of repair and / or replacement, process that was mostly concluded at the end of year 2011.

Goodwill

Goodwill is allocated to the groups of cash-generating units that are expected to benefit from the synergies of the combination. The goodwill generated by the investment in Arauco do Brasil S.A. (formerly Tafisa) was allocated to the Pien panel segment plant. The recoverable amount of the cash-generating unit was determined based on calculations of its value in use. For this calculation we used the expected future cash flows based on the operational plan approved by the management for 10-year period, applying a discount rate of 10%, which does not exceed the long-term average growth rate for the panel segment in Brazil. As of December 31, 2012 this goodwill amounted to ThU.S.$ 51,649 (ThU.S.$ 56,267 as of December 31, 2011) for a total of goodwill of ThU.S 58,645. The change in the balance of goodwill from Brasil is due only to the exchange difference on translation. Therefore, there has been no impairment losses recognized for the years ended December 31, 2012, 2011 and 2010.

NOTE 18. PROVISIONS, CONTINGENT ASSETS AND CONTINGENT LIABILITIES

Lawsuits or other Legal Proceedings

The contingent liabilities that Arauco deems appropriate to disclose are as follows:

Celulosa Arauco y Constitucion S.A.

1.On April 27, 2005, the National Defense Council (Consejo de Defensa del Estado) filed a civil lawsuit against Celulosa Arauco y Constitucion S.A. for reparation of environmental harm and indemnification, caused by the Valdivia Mill Plant, before the First Civil Court of Valdivia (Primer Juzgado Civil de Valdivia) (Rol 746-2005).

The Company filed its response, arguing that it is not responsible for the environmental damages and therefore that the indemnification payments as well as the alleged reparation, are inadmissible. Currently, expert reports have already been submitted, most of which were against the Company’s position. On September 5, 2011, observations regarding the experts’ reports were presented. The inspection of the court was held on 13^th, 14^th and 15^th of March 2012. The National Defense Council requested the Court to certify the expiration of the term to provide evidence. On September 11, 2012, the Court ordered the total re-foliation of the case file. On September 12, 2012, the Court rejected the National Defense Council’s request to hold the judgment hearing. On January 10, 2013, the ruling was notified to the parties for the purposes they may deem fit. On January 15, 2013, the Company requested a term in order to exercise the rights arising from the re-foliation. The cause is pending.

2.On August 25, 2005, the Chilean Servicio de Impuestos Internos (the “Chilean IRS”) issued tax calculations No. 184 and No. 185 of 2005, objecting to certain capital reduction transactions effected by Arauco on April 16, 2011 and October 31, 2001, and furthermore, requested reimbursement from the Company for amounts returned to it in respect of certain claimed tax losses. On November 7, 2005, the Company requested a Review of the Supervision Action (Revisión de la Actuación Fiscalizadora, or “RAF”), which is an administrative review of the tax action brought by the Chilean IRS, and filed a claim disputing the abovementioned tax calculations No. 184 and 185 of 2005. The RAF was resolved on January 9, 2009 by the Chilean IRS, which resolution, however, only partially sustained the Company’s request. In response, the Company filed an additional complaint with regard to the portion of the RAF that was not granted by the administrative review. On February 19, 2010, the Court acknowledged receipt of the Company’s request. Subsequently, the tax authority issued a report and the Company commented on such report. As of the date of issuance of these financial statements, the investigation in respect of this complaint is pending.

Considering that the position of the Company is supported by solid legal arguments, there is a reasonable likelihood of a favorable outcome for the Company.

3. On September 22, 2011 Celulosa Arauco y Constitucion S.A. was notified of a civil claim for compensation of prejudice for an alleged tort liability, filed by twelve fishermen of the Mataquito river before the Court of First Instance, Guarantee and Family of Licantén under Docket number 73-2011, arising out of the dead fish allegedly found in the Mataquito river on September 5, 2007 caused by the Licancel Plant. The plaintiffs seek to be compensated for alleged damages that they have suffered from the aforementioned event, including lost profits, harm and suffering and an alleged contractual liability. The reconsideration appeal filed by the Company against the evidentiary ruling is still pending.

F-61

4. On December 20, 2012, the Company was notified of the civil damages claim in summary proceedings, lodged by a group of settlers in the La Concepción sector, near to the Nueva Aldea Plant, the settlers are claiming compensation for alleged environmental damages that affected their quality of life. The claim demands monetary and non-monetary damages. The purported damages refer to atmospheric emissions, pollution in streams, risks related with truck transit and forest fire risks.

On December 27, 2012, the Company requested and obtained from the Court that the lawsuit be treated as ordinary and not summary proceedings. The term for answering the claim is still pending.

Alto Paraná S.A.

1.(i)On October 8, 2007, the Federal Administration of Public Income (Administración Federal de Ingresos Públicos) (“AFIP”) initiated an ex oficio proceeding against the Company’s Argentine affiliate Alto Paraná S.A. (“APSA”) questioning whether APSA erred in deducting from its income tax liability certain expenses, interest payments and exchange rate differences generated by Private Negotiable Obligations which were issued by APSA in 2001 and paid in 2007.

On November 20, 2007, APSA submitted a counterclaim to the claims presented by AFIP, completely rejecting all of AFIP’s allegations and asserting legal arguments that justify its actions in the determination of its tax burden.

On December 14, 2007, AFIP notified APSA that its counterclaim had been dismissed, thus issuing an ex-oficio ruling and ordering the payment, within 15 working days, of the calculated income tax difference for the 2002, 2003 and 2004 fiscal years of $417,908,207 argentine pesos including capital (ThU.S.$ 85,070 at December 31, 2012), compensatory interest, and fines for omission.

On February 11, 2008, APSA appealed the aforementioned ruling before the National Tax Court (Tribunal Fiscal de la Nación) (“TFN”).

On February 8, 2010, APSA was notified of TFN’s ruling, which confirmed the ruling issued by AFIP, with court expenses, based on arguments different from those that justified AFIP’s ex-oficio decision. This decision by the TFN extinguished the administrative process. As a result, the Company’s only remaining option was to pursue a remedy before the Contentious Administrative Matters Federal Appeals Court (Cámara de Apelaciones en lo Contencioso Administrativo Federal) (“CACAF”) and, subsequently, the National Supreme Court of Justice (Corte Suprema de Justicia de la Nación).

On February 15, 2010, APSA appealed before the CACAF, making all necessary submissions with the purpose of attaining a revocation of the contested decision. APSA paid litigation fees (tasa de justicia) in the amount of $5,886,053 Argentine Pesos (ThU.S.$1,196 at December 31, 2012).

On March 18, 2010, the CACAF, issued a court decree in which it ordered the AFIP to refrain from requesting the blocking of preventive interim relief measures, administratively demanding payment, issuing debt invoices, or initiating judicial collection actions, including seizure of property and other enforcement measures, against APSA until CACAF reaches a decision on APSA’s request for an injunction.

On May 13, 2010 the CACAF decided to grant the injunction requested by APSA, ordering to suspend the enforcement of the AFIP resolution until the final decision on this matter. This injunction was granted by the CACAF subject to the granting of a corresponding bond. On

F-62

May 19, 2010, APSA filed with the Appeal Court a surety policy issued by Zurich Argentina Cía. de Seguros S.A. On May 20, 2010, the CACAF asked APSA to specify the areas covered by the suretyship insurance. On May 28, 2010 APSA complied with this request and attached Endorsement No. 1 of the surety policy in favor of the CACAF – Trial Chamber I – in the amount of $ 633,616,741 Argentine pesos (equivalent to ThU.S.$128,981 as of December 31, 2012), which includes initial capital, plus adjustments and interests to the date of the bond. On June 2, 2010 the CACAF accepted this surety filed by APSA and sent notice to AFIP of the injunction granted. On June 4, 2010 the AFIP was notified of the ruling dated May 13, 2010, which is final since June 22, 2010.

On February 01, 2013, APSA received notice of the decision dated December 28, 2012, whereby the I Chamber of Appeals rejected the appeal lodged by the Company, confirming the ex officio determination of the AFIP, and imposed the judicial fees for both instances as per their generation, since there was contradictory case law. The Company appealed this decision before the Supreme Court of the Nation via the various procedural remedies available at law. On February 4, 2013, the Company filed an ordinary appeal against the Chamber’s decision and on February 19, 2013, it also filed an extraordinary appeal against the same judgment, both before the Supreme Court of the Nation.

The reasoning of the Chamber of Appeals’ decision did not modify the opinion of our external counsel in that the Company acted in accordance with law when deducting the interest, expenses and exchange differences in the indebtedness challenged by the State, and they still hold that there are good possibilities for the decision to be quashed, rendering without effect AFIP’s ex officio determination. For this reason, we have not made debt provisions in any of the fiscal years during which said negotiable obligations were in effect.

(ii)Within the course of this case’s proceedings, and particularly regarding payment of the litigation fees (tasa de justicia) before the TFN, on July 18, 2008, the Examining Officer ordered APSA to pay $ 10,447,705 Argentine Pesos (ThU.S.$2,124 at December 31, 2012) as payment of Tasa de Actuación (Litigation Fee) before the TFN. On August 14 2008, APSA filed a petition with the court requesting that this order be reconsidered, or in the alternative, rejected on the grounds that the requested amount was unreasonable. APSA provided evidence that it had paid $ 1,634,914 Argentine Pesos (ThU.S.$332 at December 31, 2012), considering that this was the actual amount due, pursuant to Law, for the Tasa de Actuación (Litigation Fee). On April 13, 2010, the First Courtroom of the CACAF denied APSA’s appeal. On April 26, 2011 APSA filed an ordinary appeal against the latter decree before the Supreme Court of the Justice, which was granted on February, 3, 2011. On June 23, 2011 the brief with the ordinary appeal was filed before the Supreme Court. On July, 14, 2011 the AFIP answered the petition of this brief. On May 8th, 2012, the Supreme Court ruled that the ordinary remedy was wrongly admitted, since the appealed sentence was not a final ruling. The case file was returned to Chamber I of the National Appeals Court of Adversarial Administrative Matters. On June 15th, 2012, APSA requested that the case be suspended until the substantial issues of the case were resolved, a request which was rejected by the CACAF on June 25th, 2012. On July 2, 2012, APSA filed a motion to reconsider, requesting that such ruling be rendered ineffective and the extraordinary proceeding be suspended until the substantial issues of the case were ruled on, also expressing that it still maintained its interest in the extraordinary remedy that was submitted. On August 21, 2012, APSA filed a presentation which expressed its interest to maintain the extraordinary appeal. Based on their analysis of the grounds underlying the appeal, APSA’s counsel has an optimistic view of the case.

2. On November 28, 2008, Alto Paraná S.A. (APSA) was notified of Resolution 212 issued by the Argentine Central Bank (BCRA) on November 19, 2008, by which the BCRA ordered Indictment No. 3991 questioning the timely liquidation of certain foreign currency.

F-63

With respect to APSA’s export proceeds. APSA responded to the charges in a timely and correct manner. Currently, the report is in Nº 8 Economic Criminal Court, 16 Secretariat.

As of the date of these consolidated financial statements and considering the preliminary state of proceedings, Alto Paraná S.A. (APSA) legal advisors are not in a position to estimate the outcome. Therefore, with the understanding that there are no legal grounds for the charges, no provision has been made for this claim. At the closing date there are no other contingencies that might significantly affect the Company’s financial, economic or operational conditions.

NOTE 20. BIOLOGICAL ASSETS

Biological assets comprise of plantations forestry, of mainly radiata and taeda pine, and to a lower extent of eucalyptus. The plantations are located in Chile, Argentina, and Brazil, with a total surface of 1.6 million hectares, out of which 961 thousand hectares are used for forestry planting, 391 thousand hectares are native forest, 148 thousand hectares are used for other purposes and 60 thousand hectares not yet planted.

As of December 31, 2012, the production volume of logs totaled 18.7 million cubic meters (18.4 million cubic meters as of December 31, 2011).

The main considerations in determining the fair value of biological assets include the following:

• Arauco uses the discounted expected future cash flows of its forest plantations, which are based on a harvest projection date for all existing plantations.

• Current plantations forestry are current expectations total volume does not decrease, with a minimum equal to the current supply demand.

• Future plantations are not considered.

• The harvest of plantations forestry supplies raw material for all other products that Arauco produces and sells. By directly controlling the development of forests that will be processed, Arauco ensures to itself, high quality timber for each of its products.

• Expected cash flows are determined in terms of harvest and expected sale of forestry products, associated with the demand from the Company’s owned industrial centers and sales to third parties at market prices. Sales margin is also considered in the valuation of the different products that are harvested in the forest. Any changes in the fair value of the plantations are recognized in profit or loss in the line item other income within the statement of income. Changes in fair value of biological assets were ThUS$231,763, ThUS$229,889 and ThUS$221,501, for the years ended December 31, 2012, 2011 and 2010, respectively. As a result of measuring biological assets at its fair value a higher cost of sales of ThUS$239,403, ThUS$253,019 and ThUS$200,320 was recognized for the years ended December 31, 2012, 2011 and 2010 resulting from the difference between the cost of wood at fair value versus actual cost incurred.

• Plantations forestry are harvested according to the needs of Arauco’s production plants.

• The discount rates used are 8% in Chile, 12% in Argentina and 8% in Brazil.

• It is expected that prices of harvested timber are constant in real terms based on market prices.

• Cost expectations with respect to the lifetime of the forests are constant based on estimated costs included in the projections made by Arauco.

• The average crop age by species and country is:

	Chile		Argentina		Brazil
Pine		24		15		15
Eucalyptus		12		10		7

F-70

The following table sets forth changes in fair value of biological assets considering variations in significant assumptions considered in calculating the fair value of the assets:

		ThU.S.$
Discount rate	0.5		(121,373	)
	-0.5		128,185
Margins (%)	10		404,854
	-10		(404,854	)

Differences in valuation of biological assets, in the discount rate and in the margins are recognized in the Statement of Income under line items “other income” and “other expenses”, as appropriate.

Plantations forestry classified as current Biological assets are those to be harvested and sold within twelve months after the reporting period.

The Company has contracted fire insurance policies for its plantations forestry, which in conjunction with company resources and efficient protection measures for these forestry assets allow financial and operational risks to be minimized.

Uruguay

Arauco owns biological assets in Uruguay through a joint venture with Stora Enso, which is accounted for in these consolidated financial statements under the equity method (see Note 16).

As of December 31, 2012, Arauco’s investment in Uruguay represented a total of 135 thousand hectares, out of which 78 thousand hectares are allocated to plantations, 6 thousand hectares to native forest, 45 thousand hectares for other uses, and 6 thousand hectares for planting.

Detail of Biological Assets Pledged as Security

There is no forestry plantations pledged as security, except for those owned by Forestal Río Grande S.A. (affiliate of Fondo de Inversiones Bio Bio, a special purpose entity). In October 2006, Forestal Río Grande S.A. has pledged its forestry plantations with prohibition to sell and encumber them to secure its liabilities with JPMorgan and Arauco.

As of December 31, 2012, the fair value of these forests was ThU.S.$2,394 (ThU.S.$9,322 as of December 31, 2011).

Detail of Biological Assets with Restricted Ownership

As of the date of these consolidated financial statements, there are no biological assets with restricted ownership.

No significant government grants have been received.

NOTE 21. ENVIRONMENT

Environment Management

For Arauco, sustainability means management strategy. This strategy incorporates values, commitments and standards, that together with the adoption of best practices as well as the use of the latest available technologies, seek to continuously improve the Company’s environmental management. It is the environmental department and each of its specialists that ensure these guidelines are met and are put in to practice in everyday company operations.

All of Arauco’s production units have certified environmental management systems, which reinforce the Company’s commitment to environmental performance and ensure the traceability of all raw materials used.

Arauco uses several supplies in its productive processes such as wood, chemical products, and water, etc., which in turn produce liquid and gas emissions. As a way to make the Company’s environmental management more efficient, significant progress has been made to reduce consumption and emissions.

Environmental investments have been made related to the control of atmospheric emissions, process improvements, water and waste management, as well as effluent treatment, in order to improve the environmental performance of all of Arauco’s business units.

F-77

Valuation techniques and assumptions applied for the purpose of measuring fair value

The carrying amount of trade and other receivables, trade and others payables, accounts payables related parties, cash and cash equivalents, and other financial assets and liabilities approximate their fair value due to the short-term nature of such instruments, and, in the case of trade and other receivables, due to the fact that any loss resulting from its recoverability is already reflected in the provision for impairment losses.

The fair value of non-derivative financial assets and financial liabilities that are not traded in active markets is an estimated through the use of discounted cash flows that are calculated over market variables that are observable at the date of the financial statements.

The fair values of bonds issued were determined with reference to quoted market prices as they have standard terms and conditions and traded on an active liquid market.

The fair value of bank borrowings were determined based on discounted cash flow analysis, applying the corresponding discount yield curves to the remaining term to maturity.

The following table sets forth the current portion of the non-current bank borrowings and debt issued as of December 31, 2012 and 2011

Swaps hedging Bonds Serie H

Hedged Item

In March 2009, Arauco issued Bonds Serie H for total of U.F. 2,000,000 at an annual interest rate of 2.25% payable semi-annually (in March and September of each year). In order to mitigate the risk of variability of cash flows from changes in the exchange rate, Arauco entered into two cross-currency swaps that fully hedge the total amount of the bond issued:

Hedging instrument

Contract 1: Arauco receives semi-annual interest (in March and September of each year) based on a notional amount of 1,000,000 UF at a 2.25% annual interest rate, and pays semi-annual interest (in March and September of each year) based on a notional amount of US$ 35.7 million (equivalent to 1,000,000 UF at the exchange rate at the date of the contract) at an annual interest rate of 4.99%. The swap matures on March 1, 2014. The fair value of the swap was ThU.S.$9,726 as of December 31, 2012.

Hedging Strategy

Considering that Arauco has a high percentage of assets denominated in U.S. Dollars (its functional currency), it is exposed to the risk of exchange rate as it has bonds issued denominated in U.F. (Chilean inflation-indexed, peso-denominated monetary unit). The objective of entering into cross currency swaps is to hedge the variability in cash flows for the U.F. exchange rate, exchanging the cash flows from the bonds issued denominated in U.F., with cash flows in U.S. Dollar at a fixed exchange rate determined at inception of the cross currency swaps.

Loans and receivables are measured at amortized cost using the effective interest rate method and are tested for impairment. Financial assets that are classified as loans and receivables are: cash and cash-equivalents, time deposits, repurchase agreements, trade and other current/non-current receivables, and account receivables from related parties.

The investment objective of time deposits and repurchase agreements is to maximize in the short-term the amounts of cash surpluses. These instruments are authorized by Arauco’s Investment Policy, which allows investing in fixed income securities. These instruments have a maturity of less than three months from the date of acquisition.

Trades and Other Receivables: These represent enforceable rights for Arauco resulting from the normal course of the business.

Other Receivables: These correspond to receivables from sales, services or loans that are not considered within the normal course of the business.

The provision for doubtful accounts is presented as a deduction of trade and other receivables. The provision for doubtful accounts is established when there is objective evidence that Arauco will not receive payments under the original sale terms. Provisions are made when the customer is a party to a bankruptcy court agreement or cessation of payments, and are written-off when Arauco has exhausted all levels of recovery of debt in a reasonable time.

Accounts receivable from related parties: Represent enforceable rights for Arauco generated in the ordinary course of business, calling it normal to the line of business, activity or purpose of the operation and financing, in which Arauco owns a non-controlling interest in the ownership of the counterparty.

Fair Value Hierarchy

The assets and liabilities measured at fair value in the consolidated statements of financial position as of December 31, 2012 and 2011 have been measured based on the valuation methodologies provided in IAS 39. The methodologies applied for each financial instrument are classified according to their hierarchy as follows:

• Level 1: Quoted prices (unadjusted) in active markets for identical assets and liabilities.

• Level 2: Inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level 3: Inputs for the assets or liabilities that are not based on observable market data (unobservable inputs).

Risk Management

Arauco’s financial instruments are exposed to various financial risks: credit risk, liquidity risk and market risk (including exchange rate risks, interest rate risks and price risks). Arauco’s overall risk management program focuses on uncertainty in financial markets and to minimize potential adverse effects on Arauco’s financial profitability.

Arauco’s financial risk management is overseen by the Financial Department. This department identifies, assesses and hedges financial risks in close collaboration with Arauco’s operational units.

Credit Risk

Description

Credit risk refers to financial uncertainty at different periods of time relating to the fulfillment of obligations subscribed to by counterparties, at the time of exercising the contract rights to receive cash or other financial assets on behalf of Arauco.

Explanation of Credit Risk Exposure and How This Risk Arises

Arauco’s exposure to credit risk is directly related to each of its customer’s individual abilities to fulfill their contractual commitments, reflected in trade receivables. Furthermore, credit risk also arises for time deposits, repurchase agreements and mutual funds.

As a policy for its trade receivables, Arauco entered into insurance policies for open account sales. The insurance policies are used to cover export sales from Arauco, Aserraderos Arauco S.A., Paneles Arauco S.A., Forestal Arauco S.A., and Alto Paraná S.A. as well as domestic sales of Arauco Distribución S.A., Arauco México S.A. de C.V., Arauco Wood Inc., Arauco Colombia S.A., Arauco Perú S.A., Arauco Panels USA LLC, Flakeboard Co Ltd., Flakeboard America Ltd. and Alto Paraná S.A. (and subsidiaries). Arauco contracts its insurance policies with Continental Credit Insurance Company (rated AA- by credit agencies as Humphreys and Fitch Ratings on April 04, 2012). Until November 30, 2012, Arauco do Brasil (and subsidiaries) insured its. Domestic credit sales with Euler Hermes Insurance Company and beginning on December 1, 2012, insurance policies all credit sales in the Arauco Group are insured with the Continental Credit Insurance Company. The insurance policies cover 90% of the amount invoice with no deductible.

In order to secure a credit line or an advanced payment to a supplier approved by the Credit Committee, Arauco gives several types of guarantees, such as mortgages, pledges, standby letters of credit, certificate of deposits, checks, promissory notes, mutual loans or any other guarantee that may be requested pursuant to each country’s legislation. The procedure to issue a guarantees is established in the Arauco’s Guarantee Policy, which has the purpose to control the accounting, maturity and valuation of such guarantees.

As of December 31, 2012, the total amount of guarantees given was U.S.$ 137,91 millions, which is summarized in the following table.

F-91

Guarantees Arauco Group
Guarantees Debtors	70,092,532.13		50.8	%

-Mortgage	8	%
-Pledge	1	%
Total Guarantees	137.906.814,60		100	%

At the end of each reporting period, the Company’s maximum credit risk exposure is limited to the carrying amount of the recognized trade receivables less the amounts receivable insured by credit insurance companies and the guarantees received by Arauco.

For the year ended December 31, 2012, Arauco’s consolidated revenues from sales were ThU.S.$ 4,280,302 out of which 65,29% correspond to credit sales, 25.63% to sales with letters of credit, and 9.08 % to other classes of sales.

The customer with the largest open account outstanding did not exceed 2.81% of total.

Arauco has made no refinancing or renegotiations with its customers.

The receivables covered by credit insurance and collateral were 98.54%, therefore, Arauco’s credit risk exposure of its portfolio is 1.46%.

Explanation of Risk Management Objectives, Policies and Processes, and Measurement Methods

The Credit and Collections Department, which reports to the Financial Department, is responsible for minimizing receivables credit risk and supervising past due accounts. It is also responsible for the approval or rejection of credit limits for all sales. The standards and procedures governing the control and risk management of credit sales are set forth the Company’s Credit Policy.

For customer credit line approval and/or modification, all Arauco group companies must follow an established procedure. All Credit requests are entered into a Credit Evaluation model (EVARIE) where all available information is analyzed, including the credit line given by the credit insurance company. Subsequently, credit requests are approved or rejected by the internal committee of each company within the Arauco group considering the maximum amount authorized by the Credit Policy Department. If the credit line exceeds the maximum established amount, it is subsequently analyzed by the Corporate Committee. Credit lines are renewed on a yearly basis.

Sales with letters of credit are mainly to Asia and the Middle East. Credit assessments of the issuing banks are performed periodically, in order to obtain domestic and international credit ratings made by the principal credit rating agencies, and of their financial position over the past five years. Depending on this evaluation, it is decided whether the issuing bank is approved or confirmation of the letter of credit is requested.

All sales are controlled by a credit verification system that has set parameters to block orders from customers who have accumulated past due amounts of a defined percentage of the debt and/or customers who at the time of product delivery have exceeded their credit limit or whose credit limit has expired.

The following table sets forth the age of trade receivables as of December 31, 2012 and 2011

The amount recovered through possession of collateral, credit insurance reimbursements or any other credit enhancement during the year ended December 31, 2012 was ThU.S.$ 4,896, which represents 49,19% of the total impaired financial assets.

Explanation of any changes to risk exposure or changes in objectives, processes and policies regarding previous years’ risk management

In March 2009, Arauco implemented a Guarantee Policy in order to control accounting, valuation and expiration dates of collaterals received.

In December 2012, Arauco updated its Corporate Credit Policy.

Regarding the credit risk of time deposits, repurchase agreements and mutual funds, Arauco has in place a policy that minimizes the risk through guidelines for management of cash flow surpluses in low-risk institutions.

Currently there is a policy for provisions for doubtful accounts receivable under IFRS for all the Arauco group companies.

Investment Policy:

Arauco has an Investment Policy which identifies and limits the financial instruments and the entities that Arauco and its subsidiaries are authorized to invest in.

The company’s Treasury Department is centralized with operations in Chile. The Head Office is responsible for carrying out investments, cash flow surplus investments, and short and long term debt subscriptions. Exceptions to this rule are specific investments made through other companies where authorization is required from the Chief Financial Officer.

For financial instruments, the only permitted investments are fixed income investments and instruments with adequate liquidity. Each instrument has defined classifications and limits, depending on duration and type of issuer.

Regarding to intermediaries (such as banks, securities brokers and broker/dealers of mutual funds), a scoring methodology is used to determining the relative degree of risk of each intermediary based on their financial position and assigning score points that result in a credit risk rating to each intermediary. Arauco uses this scoring system to determine its investment limits for each intermediary.

The required information to evaluate the various criteria are obtained from published financial statements from the banks under evaluation and from the credit risk ratings of short and long term debt securities obtained from rating agencies authorized by the Superintendency of Banks and Financial Institutions (Fitch Ratings Chile, Humphreys and Feller Rate).

F-95

The criteria evaluated are: Capital and Reserves, Current Ratio, Return on equity, Net Income to Operating income Ratio, Debt to Equity Ratio and the Credit Risk rating of each entity.

Any necessary exceptions regarding investment limits in each particular instrument or entity must have the authorization from Arauco’s Chief Financial Officer.

Liquidity Risk

Description

This risk corresponds to Arauco’s ability to fulfill its financial obligations upon maturity.

Explanation of Liquidity Risk Exposure and How This Risk Arises

Arauco’s exposure to liquidity risk is mainly from its obligations to bondholders, banks and financial institutions, creditors and other payables. Liquidity risk may arise if Arauco is unable to meet the net cash flow requirements, which sustain its operations under both normal and exceptional circumstances.

Explanation of Objectives, Policies and Processes for Risk Management, and Measurement Methods

The Financial Management Department monitors on an ongoing basis the Company’s cash flow forecasts based on short and long term forecasts and available financing alternatives. In order to manage the risk level of financial assets, Arauco follows its investment policy.

F-96

The following tables details Arauco’s liquidity analysis for its financial liabilities as of December 31, 2012 and 2011. The tables have been drawn up based on the contractual undiscounted cash outflows and their remaining contractual maturities:

Type of Risk: Market Risk – Exchange Rate

Description

Market risk arises from the probability of being affected by losses from fluctuations in currencies exchange rates in which assets and liabilities are denominated, in a functional currency other than the functional currency of Arauco.

Explanation of Currency Risk Exposure and How This Risk Arises

Arauco is exposed to the foreign currency risk from currency fluctuations arising from sales, purchases and obligations undertaken in foreign currencies, such as the Chilean Peso, Euro, Brazilian Real or other foreign currencies. In the case of significant exchange rate variations, the Chilean Peso is the currency that represents the main currency risk. See note 11 for details assets and liabilities classified by currency.

Explanation of Risk Management Objectives, Policies and Processes, and Measurement Methods

Arauco performs sensitivity analyses to measure the currency risk over the EBITDA and Net Income.

Sensitivity analysis considers a variation of +/- 10% of the exchange rate over the Chilean Peso. This fluctuation range is considered possible given current market conditions at the closing date. With all other variables at a constant rate, a U.S. Dollar exchange rate variation of +/- 10% in relation to the Chilean Peso would mean an EBITDA an annual variation of +/- 0.06% (equivalent to ThU.S.$573), on the income after tax and +/- 3.64% (equivalent to ThU.S.$9,675) and 0.08% on equity (equivalent to ThU.S.$5,805).

The main financial instrument subject to the risk in exchange rate corresponds to domestic bonds issued denominated in UF and that are not hedged with cross currency swaps described in the hedge accounting disclosures.

	December 2012		December 2011
Bonds Issued in UF (P Series) (*)		3,000,000		—

Additionally, a sensitivity analysis is carried out assuming a variation of +/- 10% in the closing exchange rate on the Brazilian real, which is considered a possible range of fluctuation given the market conditions at the closing date. With all the other variables constant, a variation of +/- 10% in the exchange rate of the dollar on the Brazilian real would mean a variation on the net income after tax +/- 0.42% (equivalent to ThU.S.$555) and a change on the equity of +/- 0.42% (equivalent to ThU.S.$555).

Market Risk – Interest rate risk

Description

Interest rate risk refers to the sensitivity of the value of financial assets and liabilities in terms of interest rate fluctuations.

Explanation of Interest Rate Risk Exposure and How This Risk Arise

Arauco is exposed to risks due to interest rate fluctuations for bonds issued, bank borrowings and financial instruments that bear interest at a variable rate.

Explanation of Risk Management Objectives, Policies and Processes, and Measurement Methods

Arauco completes its risk analysis by reviewing its exposure to changes in interest rates. As of December 31, 2012, 12.4% of the Company’s bonds and bank loans bear interest at variable rates. A change of +/- 10% interest, rate is considered a possible range of fluctuation. Such market conditions would affect the income after tax at rate of +/- 4.02% (equivalent to ThU.S.$ 10,643) and +/- 0.09% (equivalent to ThU.S.$ 6,386) on equity.

Market Risk – Price of Pulp Risks

Description

Pulp prices are determined by world and regional market conditions. Prices fluctuate based on demand, production capacity, commercial strategies adopted by large-scale forestry companies, pulp and paper producers and by the availability of substitutes.

Explanation of Price Risk Exposure and How This Risk Arises

Pulp prices are reflected in revenue from sales and directly affect the net income for the period.

As of December 31, 2012, revenue due to pulp sales accounted for 43.4% of total sales. Pulp prices are fixed on a monthly basis in accordance with the market. Forward contracts or other financial instruments are not used for pulp sales.

Explanation of Risk Management Objectives, Policies and Processes, and Measurement Methods

This risk is approached in different ways. Arauco has a team of specialists who perform periodic market and competition analyses, providing tools to analyze and evaluate trends and adjust forecasts. Similarly, Arauco performs price financial sensitivity analysis in order to take the necessary safeguards to confront different scenarios in the best possible manner.

Sensitivity analysis considers a variation of +/- 10% in the average pulp price, a possible fluctuation range given current market conditions at the date of the closing balance. With all other variables constant, a variation of +/- 10% in the average pulp price would mean an EBITDA annual variation of +/- 15.90% (equivalent to ThU.S.$191 ), on the income after tax and +/- 33,63% (equivalent to ThU.S.$ 140) and +/- 1.17% (equivalent to U.S.$ 84 million) on equity.

NOTE 26. DISTRIBUTABLE NET INCOME AND EARNINGS PER SHARE

Distributable net income

As a general policy, the Board of Directors of Arauco agreed that the net income to be distributed as dividend is determined based on realized gains/(losses), net of any relevant variations in the value of unrealized assets and liabilities, which are excluded from the calculation of net income during the period such changes are made.

As a result of the foregoing, for purposes of determining the distributable net income of the Company, which is the same considered for calculating the minimum dividend required and additional dividend, the following unrealized gains/losses are excluded from the net income for the year:

1) Unrealized gains/losses relating to the fair value recorded for forestry assets under IAS 41, adding them back to net income when they are realized through sale or disposed of by other means.

2) Those generated through the acquisition of entities. These results will be added back to net income when they are realized through sale.

3) The deferred taxes associated with the amounts described in 1) and 2) above are also excluded.

F-108

The following table details the adjustments made for the determination of distributable net income as of December 31, 2012, 2011 and 2010 in order to determine the provision of 40% of the distributable net income for each year:
