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; and when we refer to Uruguay, we mean the Oriental Republic of Uruguay. All references to
tons 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). At December 31, 2011, one UF equaled U.S.$45.61 and Ch$22,294.03.

PRESENTATION OF
FINANCIAL DATA

This report includes the audited consolidated balance sheets of Arauco and our subsidiaries as of
December 31, 2011 and 2010 and the related consolidated statements of income, shareholders equity and cash flows for each of the three years in the period ended December 31, 2011, 2010 and 2009 (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, 2011, the
observed exchange rate for Chilean pesos was Ch$519.20 to U.S.$1.00, and on April 26, 2012, the observed exchange rate was Ch$484.88 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.

SELECTED CONSOLIDATED FINANCIAL DATA

The selected consolidated financial information as of December 31, 2009, 2010 and 2011 and for each of the years
then ended is derived from, should be read in conjunction with, and is qualified in its entirety by reference to, our audited consolidated financial statements which have been prepared in accordance with the International Financial Reporting
Standards or IFRS.

##### Table of Contents



|(1) | Biological assets refer to our forests and long-standing trees.
|--- | ---------------------------------------------------------------

|(2) | Accrued for the period.
|--- | -----------------------

|(3) | Denominated Stumpage in prior filings.
|--- | ----------------------------------------

|(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 non-cash revenue. 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 prior filings on Form 20-F was compliant with applicable law, including the requirements of Form 20-F, we believe that the revised methodology provides
readers of this 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 prior filings.

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, 2009 to December 31, 2011, 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.$577.09 per metric ton in April 2009 to a high of U.S.$ 1,023.1 per metric ton 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. 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. Increased competition 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
has 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 and decrease in demand for sawn timber products resulted in our decision to close five sawmills in 2008 and 2009. Also, the same situation of deteriorated market
conditions led us to close our Bossetti sawmill in Argentina in December 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 wood products to Asia accounted for 38.6% of our sales revenue in 2011 compared to 36.3% in 2010 and 32.1% in 2009 and export sales to North America accounted for 36.7% of our sales revenue in 2011 compared to 39.7% in 2010 and 43.3% in 2009.
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 continue to 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 2011, export sales, defined as sales out of the country where our goods were produced, accounted for 71.5% of our total sales revenues. During this period, 47.0% of our export sales were to customers
in Asia, 19.0% to customers in North America, 17.7% to customers in Europe, 11.8% to customers in Central and South America and 4.5% 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. All of
our operations have since reopened and are currently operating at full operational capacity, except for the Mutrún sawmill, which will not be reopened. 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
July 1, 2010 we received an advance insurance payment of U.S.$100 million, which included compensation for losses caused by physical damage (U.S.$30 million) and downtime (U.S.$70 million). During November 2010, we received an advance insurance
payment of U.S.$185 million, which included compensation for losses caused by physical damage (U.S.$75 million) and downtime (U.S.$110 million). 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, 2011, we received a total recovery of U.S.$532 million, net of U.S.$278 million in advance payments that we had already received. 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. 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 Risk factorsRisks Relating to Us and the forestry industryEnvironmental concerns led
us to temporarily suspend our operations at the Valdivia Mill in 2005 and 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 metric tons. 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. This administrative appeal was partially accepted by the CONAMA, but some of the conditions that we believe adversely affect the feasibility of the project were maintained. As a result, in September
2009, we presented another appeal in the relevant court, and as of the date of this annual report such appeal remains pending.

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.

##### Table of Contents

This environmental impact study was approved by the COREMA in February 2010, but has been partially challenged by us before the Directive Council (Consejo Directivo) primarily because it
included a future prohibition on the discharge of wastewater into the Cruces River under all circumstances, even in the case of certain emergencies. As of the date of this annual report, the Directive Council has not resolved the action presented by
us.

Resolution of our proceeding with the CONAMA or the pending appeals before the Chilean courts regarding the resolutions
that approved the environmental impact studies of the pipeline and the effluent quality improvement projects, 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 projects 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.

##### Table of Contents

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 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.$159 million). We have not established any reserve in respect of this contingency and can offer no assurance
that the Court of Appeals will issue a ruling favorable to us. If the Court of Appeals upholds the decision of the Tribunal Fiscal de la Nación, Alto Paraná will be required to satisfy the above-mentioned claim which 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, 2011, we had approximately U.S.$3,213.3 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.

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;

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 appear 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.$110 million, had an annual production capacity of 450,000 cubic meters, representing approximately 14.2% of our total panel production capacity. Although the plywood mill at Nueva Aldea
and our forest plantations are insured, our insurance is subject to deductibles and caps, including a 15-day deductible relating to our business interruption insurance for the Nueva Aldea plywood mill. We believe that the interruption of our Nueva
Aldea panel mill may result in a loss of profits of approximately U.S.$ 2.0 million during year 2012, net of the insurance coverage we may receive due to this event. We can provide no assurance that we will receive insurance proceeds to
compensate us fully for the losses we have incurred.

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.

##### Table of Contents

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 22.7% of our employees in Chile, 49.2% of our employees in Argentina and 11.3% of our employees in Brazil were unionized at
December 31, 2011. In the past, certain work slowdowns, stoppages and other labor-related disruptions have adversely affected our operations.

In Chile we experienced (i) a 10-day work stoppage in November 2009 at our Constitución, Arauco, Nueva Aldea, Horcones and Trupán-Cholguán complexes, (ii) a three-day work
stoppage in September 2009 at our Constitución, Valdivia, Arauco, Nueva Aldea, Horcones and Trupán-Cholguán complexes and (iii) 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.

In Argentina 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 principal collective-bargaining agreements in
Chile are scheduled to expire in 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.

In addition, we depend to a significant extent on employees of contractors to
which we outsource a wide range of services including operation of certain of our manufacturing facilities and management of certain of our plantations. As of December 31, 2011, we had contracts with approximately 1,002 contractors, who
employed approximately 25,456 employees. Contractors that are not affiliated with us or with each other operate our eight sawmills and five remanufacturing facilities in Chile. Under Chilean labor legislation, we are secondarily liable for the
payment of labor and the social security obligations owed to employees of our contractors. 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 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. 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.

At December 31, 2011, 76.6% of our property, plant and equipment and forest assets were directly owned by the Company and our Chilean
subsidiaries, and in 2011, 76.1% 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 2006, 2007, 2008, 2009, 2010 and 2011 were 2.6%, 7.8%, 7.1%, -1.4%, 3.0% and 4.4% 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 and the Mexican peso, among others.

##### Table of Contents

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. 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.

At December 31, 2011, 10.6% of our property, plant and equipment and forest assets were owned by our Argentinean
subsidiaries, and in 2011, 12.7% 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 rose to 9.2% and in 2011 it slowed to 7.3%. 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.

Changes in 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, the Argentine government has issued various regulations that have resulted a number of monetary and currency exchange control
measures, 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.

At December 31, 2011, 12.8% of our
property, plant and equipment and forest assets were owned by our Brazilian subsidiaries, and in 2011, 11.2% of our revenues were attributable to our Brazilian operations.

##### Table of Contents

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 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%. Antitrust approval of this transaction remains pending as
of the date of this annual report.

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 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 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;

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 4.5% in 2007, 5.9% in 2008, 4.3% in 2009, 5.9% in 2010 and 6.5% in 2011, 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 appreciated by 4.8% against the U.S. dollar in 2010, and depreciated 11.6% during 2011. The exchange rate between the real and the U.S. dollar may continue to fluctuate and may rise
or decline substantially from current levels.

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 may have a direct impact on our financial condition, results of operations and cash flows.

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 hecateres 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).

##### Table of Contents

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.$1,900 million. The project is being financed 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., Zona Franca Punta Pereira S.A., each a 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 a result of these significant recent investments we have made in Uruguay and the significant additional investments we are currently
contemplating, 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.

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. 93.0% of our total pulp sales in 2010 and 94.4% in 2011, as well as 52.4% in 2010 and 54.9% in 2011 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 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, 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.

Item 4. Information on the Company

DESCRIPTION OF BUSINESS

We believe that, as of December 31, 2011, 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 and Brazil. As of December 31, 2011, we had approximately 1.0 million hectares of plantations in Chile, Argentina, Brazil and Uruguay. During 2011, we harvested
18.6 million cubic meters of sawlogs and pulplogs and sold 5.8 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).

Based on information published by Resource Information
Systems, Inc., an independent research company for the pulp and paper industry, at December 31, 2011, 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 6.3% share of the total world production of bleached softwood kraft market pulp and a 14.4% share of the total world production 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, 14thFloor, Las Condes, Santiago,
Chile, and our telephone number is +56-2-461-7200.

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.

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 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.

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 a future pulp mill in Uruguay.

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.

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:

Forest Plantations

At December 31, 2011, our planted forests
consisted of 76.8% radiata, taeda and elliottii pine and 23.2% mainly of 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 2011, Arauco planted a total
of 75,750 hectares and harvested a total of 49,340 hectares in Chile, Argentina, Brazil and Uruguay (these amounts include, with respect to Brazil, 80% of the plantations owned by Arauco do Brasil and with respect to Uruguay, 50% of the plantations
owned in Uruguay by the Montes del Plata joint venture). We believe that our annual harvests and plantations long-term sustainable equilibrium are approximately 67.4 thousand hectares (including the Montes del Plata joint venture).

##### Table of Contents

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. The majority of our radiata pine is less than 16 years old.

At December 31, 2011, 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.At December 31, 2011, we owned approximately 1,111,085 hectares of land in Chile, of which 743,273 hectares are forest plantations.

At December 31, 2011, we owned 257,720 hectares of forest and other land in Argentina, 173,079 hectares of forest and other land in Brazil and 132,663 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 175,829 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, 2011.

Land Acquisition and Afforestation

Our total land assets have increased from fewer than 170,000 hectares in 1980 to 1,674,547 hectares at December 31, 2011. That number does not include 4,251 hectares owned by third parties or the
assets owned by Forestal Río Grande S.A. as to which we have harvesting rights. In the five years ending December 31, 2011, we purchased 264,746 hectares of land, of which 13,631 hectares were purchased in Chile, 21,186 in Argentina,
107,554 in Brazil and 123,366 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.

##### Table of Contents

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.

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, at December 31, 2011, 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, 2011, we had eight 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-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 and MDF 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.

operations, including planting, maintenance, thinning, pruning, harvesting, transportation and access road construction. As of December 31, 2011, we had arrangements with more than 335 independent contractors that employed over 12,519 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 genetically engineering
our trees to be more tolerant to the 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 primarily consists 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. 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 18.6 million cubic meters of logs during the year ended December 31, 2011, consisting of 9.2 million cubic meters of sawlogs, 6.7 million cubic meters of radiata pine
pulplogs and 2.7 million cubic meters of eucalyptus pulplogs and other logs. We did not export any pulplogs during 2011 because substantially all of the pulplogs from our forests were used in our pulp or panel mills. During 2011, our sawmills
and panel mills used 6.15 million cubic meters of sawlogs, and no sawlogs were exported. We also sold 2.4 million cubic meters of sawlogs to unaffiliated domestic sawmills during 2011.

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 2011. For the year ended December 31, 2011, pulp sales were
U.S.$2,060.8 million, representing 54.7% of our total sales revenue for the period.

Pulp obtained from wood fibers is 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 durability and strength to paper products. 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 combined 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 the sheets are formed and subsequently dried and baled for transport to customers. The lignin and bark produced during this process is used to fuel the boilers
that 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

At
December 31, 2011, 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 metric tons. Our six pulp mills produced 2.4 million metric
tons of bleached pulp and 0.4 million metric tons of unbleached pulp in 2011.

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 scheduled every 12 months.

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

Chile

Arauco I.Arauco I, which was completed 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 a significant portion 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 metric tons 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 fundamentally 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 metric tons 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 is 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, 2011, the Constitución Mill was the largest unbleached softwood market pulp mill in the world,
with an installed annual production capacity of approximately 355,000 metric tons. 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 Constitución Mill is equipped to produce elementary chlorine-free pulp.

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 140,000 metric tons 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 environmental scrutiny
by Chilean environmental regulators and the public, which arose 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 discharges 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. Environmental concerns led us to suspend our operations at the Licancel Mill, which adversely affected our business, financial condition, results of operations and cash flows and Item 8. Financial Information-Legal
Proceedings.

Valdivia Mill.We completed construction of the Valdivia Mill during
the first quarter of 2004 and 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 metric tons 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 metric tons 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 wastewaters were discharged prior to our use 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 metric tons 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 1,030,000 metric tons
to 1,200,000 metric tons 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 kraft market pulp facility in Argentina. The mill has an installed annual production capacity of 350,000 tons of pulp, of which
50% is bleached softwood pulp, 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 tons, a port and a
power generation facility based on renewable sources, all located in Punta Pereira, department of Colonia, Uruguay. The total estimated investment is U.S.$1,900 million. After securing the necessary permits, we broke ground in May 2011 to begin
construction. In September 2011, our Uruguayan joint venture companies entered into two credit facilities to finance 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 2011, we were approximately 24.9% complete with construction. We currently anticipate initiating operations in 2013.

Production Costs

Based on information published by Resource Information Systems, Inc., our cash costs for softwood pulp production are significantly 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 significantly 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 costs of market pulp producers in selected regions in the
Northern Hemisphere for the year ended December 31, 2011.

##### Table of Contents

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 metric tons for 2011, according to Resource Information Systems, Inc., our Company was the worlds largest single
producer of unbleached softwood market pulp, with 14.4% of the total market in 2011. During the year ended December 31, 2011, 88.7% 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 consistency of our pulp
derives from our high-quality 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 generally 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 and the availability of substitutes. SeeItem 5.

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, 2011, more than 424 clients. As of December 31, 2011, 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, 2011, sales of panels were U.S.$1,273.7 million, representing 29.1% of our total sales revenues.

Exports, which include sales to countries other than the countries in which the goods are produced, accounted for 45.9% of our total
sales revenues of panels for the year ended December 31, 2011. 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.

Aserraderos Arauco S.A. was established in 1993 to centralize management and control production in our
sawmill and remanufacturing operations. Our sawmills and remanufacturing facilities in Chile are currently operated by independent contractors that are paid sawing service fees calculated on a fixed and variable basis depending on productivity, with
price renegotiations in the event of material changes in costs or productivity. Each of our 12 independent contractors operates exclusively for us and only with respect to one sawmill or remanufacturing facility.

##### Table of Contents

We believe that our arrangements with independent contractors have provided us with greater flexibility and efficiency than performing such activities on our own. We operate our sawmill and
remanufacturing facilities in Argentina.

As of December 31, 2011, 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. Contractors that are not related to us or to each other operate our eight sawmills in Chile. 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, 2011, we also own six remanufacturing facilities, five 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 367 cubic meters of remanufactured wood products in 2011.

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.

The following is a brief description of our sawmills and remanufacturing facilities and their production capacity, as of
December 31, 2011.

production capacity of approximately 65,000 cubic meters of remanufactured wood products.

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, 2011, sales
of forestry products were U.S.$157.5 million, representing 3.6% 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

As part of our efforts to reduce greenhouse gas emissions, we utilize renewable fuels such as our forest biomass for the power plants that cogenerate the steam and electricity required for our
manufacturing operations. 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 energy, 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, 2011, 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 sold 1,070,787 Certificate of Emission Reductions (CERs or carbon credits) to date. With
this issuance, we became the first Chilean forestry company to issue CERs through the CDM of the Kyoto Protocol. The following table presents the total amount of CERs sold by Arauco for each of the years indicated:



|          |  |                         |         |  |      |  |         |      |  |  |         |  |  |      |   |  |  |  |   |

During the second half of 2010, we began operations in the Horcones complex of a new biomass
co-generation power plant unit, which consists of a power boiler with capacity to produce 210 tons of steam per hour and a 31 Megawatt co-generating steam turbine. We expect the expanded power plant in the Horcones Complex to provide approximately
24 Megawatts of surplus power to the SIC. This new biomass power plant unit was successfully registered as a CDM project in January 2011.

In early 2010, we began construction of the Viñales biomass power plant, which is located alongside the Viñales sawmill in the Seventh Region of Chile. The new plant will include a
biomass-fueled power boiler with capacity to produce 210 tons of steam per hour and a 40 Megawatt steam turbine. We expect to complete construction and begin operations by the first half of 2012.

During the second half of 2011, we completed the second Carbon Footprint calculation for the Arauco Groups 2010 greenhouse
emissions. This excercise responds to Araucos strategy of assessing the impact of its industrial operations and, in particular, to Climate Change. The Company believes these calculations will be a valuable input in the process for setting 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.



38



---

##### Table of Contents

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 Flakeboard Company
Limited and Roseburg Forest Products Co.; in Asia, producers from Malaysia and China, and in the Middle East, European producers.

For sales of PBO, we focus on the Latin American market, where we compete with Duratex S.A., Masisa S.A., Berneck S.A. and Fibraplac S.A.

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 30.7% of our aggregate export volume through this port in 2011;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Lirquén. A private port in Concepción in which we have an equity interest of 20.2% and through which we shipped 39.9% of our
aggregate export volume during 2011; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | San Vicente. State-owned port near the city of Concepción through which we shipped 29.2% of our aggregate export volume during 2011.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------

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. At December 31, 2011, we had 121,596 air dry metric tons of pulp in storage in warehouses at foreign ports.

##### Table of Contents

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.

Description of Property

Our principal properties consist of land and production plants and facilities, the majority of which are located in Chile. At
December 31, 2011, we owned 1,111,085 hectares of land in Chile, over 743,273 hectares of which consist of forest plantations, and 563,463 hectares of land in Argentina, Brazil and Uruguay, of which 281,162 consist of forest plantations. In
addition, at December 31, 2011, we owned various plants and facilities, including five pulp mills, three panel mills, eight sawmills and five remanufacturing facilities in Chile; one pulp mill, one sawmill, one MDF mill, one PBO mill, one
chemical plant and one remanufacturing facility in Argentina; and one MDF mill and one MDF-PBO mill in Brazil.

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 7,441 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 disaster, which includes 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, boiler explosions and machinery breakdowns and U.S.$1
million for damages arising from all other contingencies. Deductibles for business interruption are 30 days for boiler explosions, 21 days for earthquakes and 15 days for interruptions caused by all other contingencies. 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 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, 2011, we received a total recovery of U.S.$532 million, net of U.S.$278
million in advance payments that we had already received.

##### Table of Contents

As described in more detail in 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. 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 for our business interruption
insurance relating to the Nueva Aldea plywood mill.

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, 2012, we have planned capital expenditures of U.S.$782 million, which principally include U.S.$263 million in maintenance of our
existing mills, U.S.$303 million in our new panel mill projects and capital contributions for the Montes del Plata joint venture in Uruguay and U.S.$216 million in maintenance 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.$1,900 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, 2011, our aggregate capital expenditures were U.S.$717.3 million, consisting primarily of U.S.$571.5 million in
internal projects and U.S.$145.9 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.

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.



41



---

##### Table of Contents

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.

The Evaluation Commissions and other governmental agencies may also 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). While the Ministry of the Environment and the Service of Environmental Evaluation and the Evaluation Commissions have been operating since
October 1, 2010, the authority to begin operations at the Superintendency of Environment is still pending the passage of certain legislation by the Chilean Congress, currently being reviewed by the Constitutional Court prior to its publication
in the Official Gazette. As a result, the supervision and auditing of Chiles environmental laws is currently the responsibility of the Evaluation Commissions and some other public authorities. Although certain provisions of the Law
N°20,417 are already in force, including minor procedural modifications to the SEIA, others are still subject to the publication of an administrative decree by the President of Chile. This decree is expected to be published and to become
effective during 2012.

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:

| |  |  | 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.

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.

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 22, 2011, National Law 26,737 was enacted, 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.

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.

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 69.9% of our total sales revenue for the year ended December 31, 2010, and 71.5% of our total sales revenue for the year ended December 31, 2011.
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 2011, 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 2010 and 2011, 93.0% and 94.4%, respectively, of our total pulp sales
were attributable to exports, and 52.4% and 54.9%, 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.

At December 31, 2011, 76.6% of our property, plant, equipment and
forest assets were directly owned by the Company and our Chilean subsidiaries, 10.6% by our Argentinean subsidiaries and 12.8% by our Brazilian subsidiaries. In 2011, 76.1% of our consolidated sales revenue was derived from our operations in Chile,
12.7% of our consolidated sales revenue was derived from our operations in Argentina and 11.2% of our consolidated sales revenue was derived from our operations in Brazil. Accordingly, our financial condition, results of operations and cash flows
depend, to a significant degree, upon economic conditions in Chile, Argentina and Brazil.

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, 2011, 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 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, 2011, we received a total recovery of U.S.$532 million, net of
U.S.$278 million in advance payments that we had already received. 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 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. 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 and Brazil

Chile

In 2009,
the Chilean GDP contracted 1.0%, mainly due to the global financial crisis. In 2010 and 2011, Chilean GDP returned to growth rates of 6.1% and 6.0%, respectively. See Risk factorsRisks relating to Chile.

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 Argentinepeso 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 2011
Argentinas GDP growth rose to 7.3%. 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
Risk factorsRisks relating to Argentina.

Brazil

Brazils GDP increased by 2.8% in real terms during 2011, compared to a growth rate of 7.5% in 2010 and a negative growth rate of
0.2% in 2009. In 2009, the real depreciated against the dollar by 25.5%, in 2010, the real appreciated against the dollar by 4.8% and in 2011, the real depreciated against the dollar by 11.6%. See Risk factorsRisks relating to
Brazil.

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 2011, the value of the Chilean peso relative to the U.S. dollar
decreased 9.9% in nominal terms and 8.6% in real terms, based on the observed exchange rates on December 31, 2010 and December 31, 2011. The observed exchange rate on April 26, 2012 was Ch$484.88 to U.S.$1.00. For information regarding
historical rates of exchange in Chile from January 1, 2007, 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 commissions paid to our sales agents abroad) and a significant part of our
indebtedness is denominated in U.S. dollars. As of December 31, 2011, our U.S. dollar-denominated indebtedness was U.S.$2,559.6 billion. 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. For additional discussion regarding recent movements in the price of pulp, seeTrend Information.

However, future developments in the Chilean, Argentine, Brazilian and Uruguayan
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, and Risks Relating to Uruguay.

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.

The following table sets forth, for the periods indicated, average unit sales prices for our products.

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.

##### Table of Contents

Prices for unbleached softwood market pulp also follow cyclical patterns related to
worldwide demand, stock levels and supply. Unbleached softwood market pulp represents about 3.5% 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 2011, pulp prices for all grades decreased with respect to 2010,
which was mainly explained by lower demand from Asia and Europe, 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Trend Information.

Price of NBSK

The market price for NBSK was U.S.$869.30 at December 31, 2007, which represented an increase of 19.1% as compared to
December 31, 2006. The market price for NBSK was U.S.$641.51 at December 31, 2008, a 26.2% decrease as compared to December 31, 2007. The market price of U.S.$798.77 per ton recorded at 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 at 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 at
December 31, 2011, a 12.1% decrease as compared to December 31, 2010.

Price of BEKP

The market price for BEKP at December 31, 2007 reached U.S.$775.20, which represented a 15.4% increase over the price at
December 31, 2006. At 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 at December 31, 2009 reached U.S.$700.00, which
represented a 19.8% increase of over the price at December 31, 2008. The market price for BEKP was U.S.$849.21 per ton at 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 at December 31, 2011, a 23.2% decrease as compared to December 31, 2010.

Price of UKP

The market price for unbleached kraftwood pulp, or UKP, reached U.S.$586.9 per ton at December 31, 2007 reached U.S.$598.5, which
represented a 19.8% increase over the price at December 31, 2006. The market price for UKP at December 31, 2008 dropped to U.S.$455.76, which represented a decrease of 23.8% as compared to December 31, 2007. The market price for UKP
at December 31, 2009 was U.S.$603.65, which represented a 32.4% increase over the price at December 31, 2008. The market price for UKP was U.S.$751.85 per ton at December 31, 2010, a 24.6% increase as compared to December 31,
2009. The market price for UKP was U.S.$603.65 per ton at December 31, 2011, a 18.9% decrease as compared to December 31, 2010.

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.

In 2007, the health of the construction sector was affected by a significant stock of unsold houses, which caused the amount of
construction to fall 30% in the United States as compared to 2006. This negatively affected the sales volume of wood. Prices of moldings and wood continued to decrease. In Europe, consumer trends favoring products with a sustainable forestry
management certification increased demand for the entire range of Araucos panels. In the United States, the strong contraction of the real estate sector adversely affected the sale of MDF moldings. This was offset, however, by the strong
increase in the demand for MDF boards in Latin America. In the case of Araucos plywood panels, demand increased as a result of a decrease in the supply from other manufacturers and by the highly diversified applications of these products
unrelated to the construction sector.

The slowdown in the global growth markets during 2008 continued to affect the demand
for timber in all markets. The construction sector continued to decline 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.

##### Table of Contents

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 sawn timber 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 in 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 has been a slight trend of recovery as compared with 2009 and 2010. This recovery has been 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%.

Prices for our pulp, 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,
| | - |  | ------------------



| |  |  | 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 a additional information relating to the accounting treatement of our biological assets, seeCritical Accounting PoliciesBiological Assets.

##### Table of Contents

Selling expenses consist primarily of per ton fees we paid to our selling agents. Traffic,
shipping and freight costs are the costs of carrying the product to the 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 6.8% 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 66.5%, as compared to 61.0% in 2010.

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.

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 financial assets and liabilities on its balance sheet 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 balance sheet 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.

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 balance sheet 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.

Results of Operations

The following table provides a breakdown of our
financial results of operations and sales volumes as of and for the years ended December 31, 2009, 2010 and 2011. Both the table and the discussion that follows are based on and should be read in conjunction with our audited consolidated
financial statements, including the notes thereto, as of December 31, 2009, 2010 and 2011 included elsewhere herein. The audited consolidated financial statements included herein are prepared in U.S. dollars and in accordance with IFRS.

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 16.3% 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.

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.$2,298.8 million in 2010 to U.S.$2,908.5 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 margin

Our gross margin decreased from 39.0% for 2010 to 33.5% 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 operating income

Other operating 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.

Distribution costs

Distribution costs for all markets increased 25.4% from U.S.$360.2 million in 2010 to U.S.$451.6 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.

##### Table of Contents

Financial costs

Interest expenses 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 63.2% 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 expenses

We had tax expenses 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 profit

Net consolidated profit 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.

Year Ended December 31, 2009
Compared to Year Ended December 31, 2010

Revenue

Revenue increased 21.6% from U.S.$3,097.4 million in 2009 to U.S.$3,767.4 million in 2010, primarily as a result of:



| |  |  | a 33.6% increase in revenue from panels;
| | - |  | ----------------------------------------



| |  |  | a 11.3% increase in revenue from pulp;
| | - |  | --------------------------------------



| |  |  | a 25.7% increase in revenue from wood products; and
| | - |  | ---------------------------------------------------



| |  |  | a 84.1% increase in revenue from forestry products.
| | - |  | ---------------------------------------------------

Pulp

Revenue from bleached and unbleached pulp increased 11.3% from
U.S.$1,596.5 million in 2009 to U.S.$1,777.1 million in 2010, reflecting a 48.1% increase in average prices, partially offset by a 24.8% decrease in sales volume. Sales of bleached pulp increased 9.9% due to a 48.8% increase in average prices,
partially offset by a 26.2% decrease in sales volume. Revenue from unbleached pulp increased 21.2% due to a 44.2% increase in average prices, partially offset by a 16.1% decrease in sales volume.

When comparing to 2009, the increase in revenues in 2010 was primarily driven by higher average pulp prices which reflected a recovery in
global demand for pulp and paper after the global financial crisis that led to a substantial decrease in the prices of our products during the last quarter of 2008 and the first quarter of 2009.

##### Table of Contents

The decrease in pulp sales volume was primarily 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 33.6% from U.S.$824.8 million
in 2009 to U.S.$1,101.6 million in 2010. This increase in revenues was primarily due to a 15.9% increase in average prices and a 15.3% increase in sales volume.

Our sales volume increased in 2010 primarily as a result of our acquisition of Tafisa Brasil in August 2009, which added 640,000 cubic meters of annual production capacity to our panels business,
partially offset by the loss in production caused by the interruption of our operations in Chile due to the February 27, 2010 earthquake.

Our average prices increased in 2010 primarily as a result of higher demand for our products during the year compared to 2009, 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 25.7% from U.S.$493.2 million in 2009 to U.S.$620.1 million in 2010,
primarily as a result of a 16.2% increase in average prices and an 8.2% increase in sales volume. During 2010, our offer for sawn timber products increased largely due to reconstruction efforts in Chile after the February 27, 2010 earthquake.
Also, the real estate and construction markets in the United States showed signs of modest improvement during the year 2010, but still remain at their lowest levels in 50 years. Homebuilding levels in the United States improved in 2010 reaching
approximately an average of 588,000 units per year, compared to an average of 554,000 units per year during 2009. All of these factors described favored demand for our sawn timber and remanufactured wood products, increasing sales volume, partially
offset by the interruption of our sawmills and the permanent closure of our Mutrún mill, after the February 27, 2010 earthquake.

Forestry products

Revenue from forestry products increased 84.1% from U.S.$81.6 million in 2009 to U.S.$150.2 million in 2010. This increase was primarily
the result of increased demand for our pulplogs and chips, revenues of which increased 120.4% and 75.5% respectively, in 2010.

Demand for our forestry products increased in 2010 as a result of the recovery from the global financial crisis, 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 16.9% from U.S.$101.3 million in 2009 to
U.S.$118.4 million in 2010. This increase was primarily the result of an U.S.$8.1 million increase in our sales of energy.

Cost of
sales

Cost of sales increased 6.8% from U.S.$2,152.5 million in 2009 to U.S.$2,298.2 million in 2010, primarily as a
result of higher forestry production costs by 33.2%, from U.S.$353.2 million in 2009 to U.S.$470.3 million in 2010 and an increase in raw materials costs, which increased 74.4%, from U.S.$146.7 million in 2009 to U.S.$255.8 million in 2010,
partially offset by lower maintenance costs which decreased 27.1 %, from U.S.$284.3 in 2009 to U.S.$207.2 in 2010. As of December 31, 2010, average costs of pulp have increased as compared to December 31, 2009. BSKP or bleached
softwood kraft pulp unitary costs increased by 10.5%, BHKP or bleached hardwood kraft pulp unitary costs slightly increased by 1.0% and UKP or unbleached kraft pulp unitary costs were 10.1% higher.

##### Table of Contents

Gross margin

Our gross margin increased from 30.5% for 2009 to 39.0% for 2010, primarily as a result of a 21.6% increase in sales revenue mainly as a result of higher average prices of almost all our products,
partially offset by a 6.8% increase in cost of sales.

Other operating income

Other operating income increased 108.7% from U.S.$181.4 million in 2009 to U.S.$378.5 million in 2010, mainly as a result of a U.S.$66.0
million increase in the fair value of our biological assets due to higher sales margin in 2010 compared to 2009 and a net gain of U.S.$107.7 million attributable to insurance claims related to the February 27, 2010 earthquake.

Distribution costs

Distribution costs for all markets decreased 3.9% from U.S.$374.6 million in 2009 to U.S.$360.2 million in 2010, primarily as a result of
a 9.5% decrease in shipping and freight costs due to a 24.8% reduction in pulp sales volume.

Administrative expenses

Administrative expenses increased 29.9% from U.S.$249.3 million in 2009 to U.S.$323.9 million in 2010, primarily as a
result of a U.S.$50.2 million increase in administrative expenses attributable to our consolidation of the labor costs of Tafisa Brasil, which we acquired and began to consolidate in August 2009. As a percentage of revenue, administrative expenses
increased from 8.0% in 2009 to 8.6% in 2010.

Financial costs

Interest expenses increased 7.0% from U.S.$193.9 million in 2009 to U.S.$207.5 million in 2010. This increase is explained primarily by
higher accrued interests of U.S.$15.0 million, of which U.S.$8.0 million came from our two bond offerings made in September 2010 and a higher negative impact of change in fair value of derivatives of U.S.$5.0 million.

Exchange rate differences

We recorded exchange rate difference gains of U.S.$17.6 million in 2009 compared to exchange rate difference losses of U.S.$16.3 million in 2010, primarily as a result of foreign exchange losses
attributable to our financial debt denominated in currencies that appreciated against the U.S. dollar, partially offset by foreign exchange gains attributable to money market investments, deposits and accounts receivables denominated in such
currencies which appreciated against the U.S. dollar. The exchange rate losses can be explained largely by the depreciation of the U.S. dollar against the Euro and the depreciation of the U.S. dollar against the Chilean peso, which caused a loss of
U.S.$28.4 million in total liabilities, partially offset by a gain of U.S.$12.1 million in total assets.

Income tax expenses

We had tax expenses of U.S.$53.5 million in 2009 compared to tax expenses of U.S.$198.0 million in 2010. This increase
was principally attributable to a higher income before taxes as a result of our 55.1% increase in gross profit in 2010 compared to 2009. Our effective tax rate increased from 14.9% in 2009 to 22.0% in 2010, mainly due to higher profits coming from
our subsidiaries in Argentina and Brazil, which have higher tax rate than our local subsidiaries, and the tax effect of income received from insurance related to the earthquake of February 27, 2010.

##### Table of Contents

On July 31, 2010 Law N. 20.455 for national reconstruction financing was published in
the Chilean Official Gazette (Diario Oficial de Chile). One of the most important changes such law introduced was the increase in the First Category Taxes for revenues received and /or accrued during commercial years 2011 and 2012, with rates of 20%
and 18.5%, respectively.

Net profit

Net consolidated profit in 2010 increased 130.0% from U.S.$304.6 million in 2009 to U.S.$700.7 million in 2010, primarily as a result of higher gross profits in almost all of our business segments due to
improved market conditions, partially offset by exchange rate difference losses and higher income tax expenses.

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.

Cash Flow from Operating
Activities

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.$656.5 million increase in payments for goods and services, partially offset by an increase of U.S.$ 622.4 million in
our collection of sales revenue and a U.S.$149.6 million increase in income tax paid. 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.

Our net cash
flow provided by operating activities was U.S.$1,137.3 million in 2010 and U.S.$751.0 million in 2009. The increase of net cash provided by operating activities in 2010 as compared to 2009 was principally due to an increase of U.S.$308.4 million in
the collection of trade accounts receivable as a result of increasing sales of our products, and an increase of U.S.$292.4 million received from insurance claims mostly related to the earthquake of February 27, 2010. This result was partially
offset by higher payments to suppliers for goods and services by U.S.$91.4 million and an increase of U.S.$72.3 million of payments to and on behalf of employees.

Our net cash flow provided by operating activities was U.S.$751.0 million during the year ended December 31, 2009 and U.S.$769.7 million during the year ended December 31, 2008. The decrease in
net cash provided from operating activities in 2009 as compared to 2008 was principally due to a lower collection of accounts receivable as a result of decreasing sales of our products. The decrease in income was explained by the global financial
crisis.

Cash Flow Used in Investing Activities

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.

Our net cash used in investing activities was U.S.$669.4 million in 2010 and U.S.$717.3 million in 2009. This decrease
was principally due to lower amounts used in business combinations by U.S.$286.5 million, partially offset by higher capital expenditures for property, plant and equipment by U.S.$240.9 million.

Our net cash used in investing activities increased from U.S.$466.7 million during the year ended December 31, 2008 to U.S.$717.3
million during the same period of 2009. This increase is primarily explained by the acquisition of Tafisa Brasil for U.S.$167.0 million in August 2009 and the acquisition of forest assets through a joint venture with Stora Enso for U.S.$167.5
million in October 2009.

Cash Flow from Financing Activities

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.

Our net cash used in financing activities was U.S.$33.9 million in 2010 compared to U.S.$302.4 million obtained from financing activities
in 2009. This decrease was mainly due to lower funds obtained by debt financing of U.S.$356.7 million, partially offset by a lower amount used to repay loan obligations by U.S.$112.4 million.

Our net cash related to financing activities increased from U.S.$378.5 million used in financing activities during the year ended
December 31, 2008 to U.S.$302.4 million provided by financing activities during the year ended December 31, 2009. This increase is mainly due to an increase in our levels of debt. In March 2009, we issued two bond series for approximately
U.S.$142.0 million in the local market and in July 2009 we issued U.S.$500 million in the U.S. market.

In accordance with
customary practice in the pulp industry, we 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.

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.

Contractual Obligations

rate and matures in December 2014.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2011, our short-term bank debt was U.S.$185.8
million of which 93.6% was U.S. dollar-denominated. As of December 31, 2011, our total long-term bank, export credit agency and multilateral lending agency debt (including the current portion of such debt) was U.S.$407.5 million of which 98.2%

the weighted average maturity of our long-term debt was 6.7 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 30, 2011, the average
interest rate for our U.S. dollar floating rate debt over nine-month LIBOR was 1.27%. As of December 30, 2011, the average interest rate for our U.S. dollar fixed rate debt was 5.70%. These average rates do not reflect the effect of swap
agreements and subsequent unwinds effective as of December 30, 2011.

On January 11, 2012, we issued U.S.$500
million aggregate principal amount of 4.75% bonds due in 10 years in the international capital markets.

We were in compliance with all bank loans and bonds covenants as of December 31, 2011.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any material off-balance
sheet arrangements.

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 internationally recognized financial institutions; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | transactions must be carried out only with banks or bank subsidiaries.
| | - |  | ----------------------------------------------------------------------

Our Argentine and Brazilian subsidiaries manage their treasury activities independently from us. Their activities are governed by cash
and deposit policies that are approved by their chief executive officers. 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.

Cross Currency Swap Agreements

We have outstanding the following cross currency swap agreements to hedge our local bonds issued in UF:



| |  |  | A cross currency swap agreement with Banco de Chile for UF 1,000,000. Under this agreement, we receive semi-annual interest based on the notional

The aggregate fair value of our currency swap agreements as of
December 31, 2011 represented a liability of U.S.$0.2 million and as of December 31, 2010 represented an asset of U.S.$53.4 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 the 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.$3.5 million for the year ended December 31, 2011 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 community involved with our industry.

TREND INFORMATION

During the last quarter of 2011, world pulp prices reached its lowest level of the year. The main reasons behind this decline were lower
demand in Europe, oversupply in Asia, credit restrictions in China and general uncertainty in the financial market.

During
October and November of 2011, the Chinese government implemented credit restrictions that had an adverse effect on pulp purchasing activity in China and resulted in rising pulp inventories. In December, the credit restrictions were eased, and as a
result of the improved credit market, and in part driven by an expectation in the market that prices would rise in 2012, Chinese paper producers commenced buying pulp at normal levels. In an effort to unload excess inventory, certain European
integrated paper producers offered large volumes at a discount, and even shifted pulp volumes from Europe to China to satisfy the increasing demand. Prices of such offers were approximately U.S.$20 to U.S.$40 under market price, which was already at
a low price level compared to the annual average. By the end of the year, paper inventories declined and downward pressure over pulp prices eased. Although paper demand was not active, paper producers had a relatively positive quarter due to a
decline in cost of raw materials, especially pulp, which depending on the paper grade, may comprise up to 70% of the total cost of sales. Other Asian countries such as Korea, Taiwan and Japan had stable demand for pulp and paper, and taking
advantage of low pulp prices, producers in these markets recorded increases in margins during the fourth quarter of 2011.

As
of the date of this annual report, the European pulp market continues to be depressed, largely as a result of the European sovereign debt crisis. 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 did not show significant improvement during the fourth quarter of 2011. The housing starts index reached 657,000 units in December 2011, which is still lower than the 10-year historical average. During the fourth quarter of 2011,
prices for our molding and timber products did not vary significantly as compared to the previous quarter.

During the first
quarter of 2012, there have been signs of recovery in international pulp prices. During this period, we saw increases in two major pulp indexes: the bleached hardwood kraft pulp index increased 16.0%, reaching U.S.$752.61 per ton, and the northern
bleached softwood kraft pulp index increased 1.79%, reaching U.S.$843.85 per ton. This was mainly the result of an increase in demand in Asia, especially in China, and an active market in Latin America.

DIRECTORS AND EXECUTIVE OFFICERS

Directors

A board of directors manages our business. Our by-laws
(estatutos) require that the board of directors consist of nine directors. Our directors cannot also be our executives. The entire board is elected every three years and can be re-elected for any number of periods. The current
board was elected in April 2010, and their terms will expire in 2013. The board may appoint replacements to fill any vacancies that occur during periods between elections; however, at the annual shareholders meeting following any such
replacement, an election of the entire board must take place. Scheduled meetings of the board of directors are, generally, held once a month. Extraordinary board meetings are called when summoned by the Chairman or when requested by at least two
directors. We do not have an audit committee or compensation committee.

Our current directors are listed below.

As of December 31, 2011, we had contracts with 1,002 contractors, who employed 25,456 employees.
Contractors that are not affiliated with us or with each other operate our eight sawmills and five remanufacturing facilities in Chile. The 12 independent contractors that operate our Chilean sawmills had 2,652 employees at December 31, 2011.
The independent contractors that operate our Chilean remanufacturing facilities had 1,950 employees at December 31, 2011 and the independent contractor that operates the laminating beams line employed 140 employees at December 31, 2011.

Under Chilean labor legislation, we are secondarily liable for the payment of labor and the social security obligations owed
to employees of our contractors. 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.

22.7% of our employees in Chile, 49.2% of our employees in Argentina and 11.3% of our employees in Brazil were unionized at December 31, 2011. We negotiate collective bargaining agreements of two or
three years duration with unionized employees.

We have stable employee relations in Chile, Argentina and Brazil. Our
Chilean operations have not experienced any work stoppages in the last five years other than (i) a ten-day work stoppage in November 2009 at our Constitución pulp mill, our Trupán-Cholguán panel mill, and our Nueva Aldea
and Horcones complexes, (ii) 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 (iii) 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.

In Argentina 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.

On December 27, 2011, the Agricultural Labor Regime Law 26,727 was enacted in
Argentina. This Law replaces Law 22,248 and its amendments, introducing significant changes in the regulatory framework, such as the creation of the National Registry of Agricultural Workers and Employers (RENATEA) which replaced the former registry
known as RENATRE. Further, this Law provides that the Labor Contract Law (Law 20,744) may also still apply, if consistent with Law 26,727. This new law reinforces the principle of joint responsibility for the payment of labor and the
social security obligations owed to our contractors employees.

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.

During the last five years, there have been no strikes or other material work stoppages at our Brazilian subsidiaries.

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

Empresas Copec is a Chilean public company listed on the Santiago Stock Exchange, the Valparaíso Stock Exchange and

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. At

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.

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.

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. The mill resumed operations in August 2005 at 80% of its authorized production capacity after 64 days of suspended operations. 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 us to temporarily suspend our operations at the
Valdivia Mill, 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

##### Table of Contents

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 the opinion of Arauco, affected the feasibility of the project. For such reason, Arauco 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. Such appeal (recurso de reclamación) was partially accepted by the CONAMA. However, some of the conditions
that affect the feasibility of the project were maintained. As a consequence, on September 17, 2009, we presented another appeal (recurso de reclamación) before the ordinary courts of justice, which appeal has not been resolved as
of the date of this annual report.

On February 19, 2009, 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, that is, in a body of water other than the Cruces River, the Carlos Anwandter Nature
Sanctuary or their sources. The pipeline would transport the wastewaters of the Valdivia mill through an extension of 37 kilometers from the Valdivia mill to Punta Maiquillahue and would finally discharge the wastewater two kilometers inside the
Pacific Ocean. Such environmental impact study was approved with certain conditions by the COREMA by resolution dated February 24, 2010. We have challenged some of these conditions before the Directive Council (Consejo Directivo) of the
CONAMA. As of the date of this annual report, the Directive Council of the CONAMA has not resolved the action presented by us. On March 26, 2010, certain indigenous communities located in San José de la Mariquina filed a constitutional
action (recurso de protección) against the COREMA of the Fourteenth Region of Chile, challenging the resolution that approved our environmental impact study in February 2010. Such action was rejected by the Court of Appeals of
Valdivia. The indigenous communities appealed before the Supreme Court of Chile, which appeal was rejected by such court on October 14, 2010.

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 or the pending appeals before the Chilean courts regarding the resolutions that approved the
environmental impact studies of the pipeline and the effluent quality improvement projects, 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 projects 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 3. Key InformationRisk FactorsRisks Relating to Us and the Forestry IndustryEnvironmental concerns led us to temporarily suspend our operations at the Valdivia Mill, 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.

##### Table of Contents

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.$159 million). We have not established any reserve in respect of this contingency and can offer no assurance that the Court of Appeals will issue a
ruling favorable to us. If the Court of Appeals upholds the decision of the Tribunal Fiscal de la Nación, Alto Paraná will be required to satisfy the above-mentioned claim which 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.

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. For information regarding the differences between Chilean GAAP and IFRS, see note 2 to our audited consolidated financial statements.

On November 27, 2007, our board of directors approved a provisory dividend for U.S.$0.95 per share, which was distributed on December 12, 2007 and charged to net income. On April 22, 2008,
our shareholders approved a final dividend for 2007, which was distributed on May 7, 2008. On November 25, 2008, our board of directors approved a provisory dividend for U.D.$0.89 per share, which was distributed on December 10, 2008
and charged to net income. On April 23, 2009, our shareholders approved a final dividend for 2008, which was distributed on May 7, 2009. In the aggregate, dividends distributed equaled 40% of our consolidated net income for 2008, on a
Chilean GAAP basis. On November 24, 2009, our board of directors approved an interim dividend of U.S.$0.2294 per share, which was distributed on December 11, 2009 and charged to net income. 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 will be distributed on May 9, 2012.
Dividends distributed equaled 40% of our consolidated net income for 2011 as determined on an IFRS basis.

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.

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 Bioernergía 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.

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:

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.

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:

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.

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;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

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.

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.

##### Table of Contents

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.

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
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | 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 will be generally subject to taxes on capital gain.

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
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.

##### Table of Contents

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. 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.

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. From time to time, we assess our exposure and monitor opportunities to manage these risks, including entering into derivative contracts. 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. At December 31, 2011, we had outstanding U.S.$3,200.2 million of indebtedness, excluding accrued interest and discounts and costs of issuance, of which 86.9% bore interest at
fixed interest rates and 13.1% bore interest at floating rates of interest. These average rates do not reflect the effect of swap agreements. 79.7% 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.

The following table summarizes our debt obligations, at
December 31, 2011. 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 at December 31, 2011.

##### Table of Contents

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 generally believe
that our foreign currency exposure is not material to our net income. We estimate that a majority of our consolidated costs and expenses are denominated in dollars. As of December 31, 2011:



| |  |  | 70% of our accounts receivable were denominated in U.S. dollars and 11% in Chilean pesos;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | 62% of our cash and short-term investments were denominated in U.S. dollars, 7% were denominated in Chilean pesos and 18% 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, 2011, 79.3% 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, 2011, we were not party to any commodity hedging arrangements.

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 Chief Accounting Officer concluded that the
disclosure controls and procedures, as of December 31, 2011, 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 Chief Accounting Officer, 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 Comptroller Director, 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, 2011.

(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 2011 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 16F. | Change in Registrants Certifying Accountant
|--------- | --------------------------------------------

On April 3, 2012, the Board of Directors approved to propose to shareholders a change in the Companys independent registered public accounting firm at the General Shareholders Meeting to be
held on April 24, 2012. On such date, the shareholders approved the Board of Directors proposal to nominate Deloitte Auditores y Consultores Ltda. (Deloitte) as the new independent registered public accounting firm for
Celulosa Arauco y Constitución S.A. Pricewaterhouse Coopers (PWC) served as the independent registered public accounting firm for Celulosa Arauco y Constitución S.A. for the 2011 and 2010 fiscal years, in each case pursuant
to the terms of an annual engagement letter. On April 24, 2012, Deloitte was notified by the Company that shareholders had approved appointment of another independent registered public accounting firm for the 2012 fiscal year, and PWC was
discharged from its engagement by the Company.

The audit reports of PWC on the Companys consolidated financial
statements as of and for the years ended December 31, 2011 and 2010 did not contain 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 two most recent fiscal years ended December 31, 2011 and 2010, and the subsequent interim periods through
April 30, 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 PWCs satisfaction, would
have caused PWC to make reference thereto in their reports on the Companys consolidated financial statements for such periods.

During the Companys two most recent fiscal years ended December 31, 2011 and 2010 and the subsequent periods through April 30, 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 PWC to 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.

The Companys Board of Directors, will engage Deloitte as the Companys new
independent registered public accounting firm to audit the Companys consolidated financial statements and internal control over financial reporting for the fiscal year ending December 31, 2012.

During the Companys two most recent fiscal years 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.

Item 16G. Corporate Governance

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Celulosa Arauco y Constitución S.A.

In
our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, comprehensive income, shareholders equity and cash flows present fairly, in all material respects, the financial position of Celulosa
Arauco y Constitución S.A. and its subsidiaries at December 31, 2011 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011 in conformity with
International Financial Reporting Standards as issued by the International Accounting Standards Board. 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. 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 audits to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An audit 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, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Functional and Reporting Currency

Arauco has defined the U.S. Dollar as its functional currency, as most of the Companys operations are a result of exports, and its costs to a large extent are related to or index-linked to the
U.S. Dollar.

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

For the sawmill and panel segments, although total sales include a mix of domestic sales and exports, 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.

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 and depreciation of equipment, which are driven mainly by global conditions and therefore, influenced mostly by the
U.S. Dollar.

The financial information included herein is presented in thousands of U.S. Dollars.

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. qualify as Special Purpose Entities. These entities are considered to be controlled by
Arauco, which is determined, by the fact that they maintain exclusive contracts with Arauco for wood provision, forward purchase of land and forest administration. Consequently, the financial information of these companies is consolidated with the
financial information of the Company and is included in these consolidated financial statements of Arauco.

Compliance and Adoption of IFRS

The accompanying consolidated financial statements of Arauco include the Balance Sheet, Statement of Income, Comprehensive Income
Statement, Statement of Changes in Net Equity and Statement of 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.

Summary of significant accounting policies

The accompanying consolidated financial statements as of December 31, 2011 were prepared in accordance with Araucos accounting policies,
uniformly applied to all items in these consolidated financial statements.



|a) | Basis for Presentation of financial statements
|-- | ----------------------------------------------

The actual Consolidated financial statements have been prepared according to international basis of financial information issued by the International Accounting Standards Board (IASB) and they represent
the integral, explicit and unreserved adoption of the mentioned international standards.

The consolidated financial statements have been
prepared under the historic cost convention, as modified for the revaluation of biological assets, financial assets and financial liabilities (including derivative instruments) at fair value.

There have been some minor reclassifications to prior year financial statements, for presentation purposes.



|b) | Critical accounting estimates and judgments
|-- | -------------------------------------------

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.

- Property,
Plant and Equipment

In a businness acquisition, management prepared the corresponding valuations based on a report issued by a third party
expert.

The carrying amounts of fixed assets 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 estimated as the higher of fair value less the cost to sell and the value in use, with an impairment charge being 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.

Sensitivity analysis associated to the estimated useful lifes are 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 balance sheet date.

Detailed financial information of Fair Value of Financial
Instruments and sensitivity analysis are presented in Note 23.

-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 calculate the valuation of forest plantations are presented in Note 20 including sensitivity analysis.

-Lawsuits and Contingencies

Arauco and
its subsidiaries are subject to certain ongoing lawsuits. Future effects on Araucos financial condition resulting from these lawsuits are estimated by the management of the Company, in collaboration with its legal advisors. Arauco reserves
appropriate contingency estimates on each balance sheet and/or upon each substantial modification to an underlying cause of any such litigation, which decisions are based on the reports of its legal advisors. Detailed lawsuits information is
presented in 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 usually requires holding shares with more than one half of the voting rights. Subsidiaries are fully consolidated from the date on
which control is transferred to the group. They are de-consolidated from the date that control ceases.

The intercompany transactions and
unrealized earnings from subsidiary operations have been eliminated from the consolidated financial statements and non-controlling interest is recognized in the equity balance.

The consolidated financial statements for year ended on December 31, 2011 and 2010, include subsidiary balances shown in Note 13 and balances of the Fondo de Inversión Bío Bío,
and its subsidiary Forestal Río Grande S.A., both of which qualify as Special Purpose Entities.

Certain consolidated subsidiaries
report statutory financial statements in Brazilian Reales and Chilean Pesos, their main functional currencies. For consolidation purposes, they have been translated as indicated in Note 1 (e) (ii).

Accounting policies for subsidiaries will be adjusted if necessary to ensure consistency with the
policies adopted by Arauco. Non-controlling interest is presented as a separate component of equity.

All intercompany transactions, accounts
receivable, accounts payable and intercompany unrealized income are eliminated.



|d) | Segments
|-- | --------

Arauco has defined its
operating segments according to its business areas, which are defined by products and services sold to customers. This 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 Executive Officer and Corporate Managing Directors of each segment are responsible for these decisions.

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



| |  |  | Pulp
| | - |  | ----



| |  |  | Panels
| | - |  | ------



| |  |  | Sawn Timber
| | - |  | -----------



| |  |  | Forestry
| | - |  | --------

Detailed
financial information by segment is presented in Note 24.



|e) | Functional currency
|-- | -------------------

(i) Functional
currency

Araucos entities are measured using the currency of the primary economic environment in which the Company operates (the
functional currency). The consolidated financial statements are presented in U.S. Dollars, which is Araucos functional and presentation currency.

(ii) Group companies

The results and financial position of all the group entities (none of which
has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:



| |  | assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet;
|- |  | -----------------------------------------------------------------------------------------------------------------------------



| |  | income and expenses for each income statement are translated at average exchange rates (unless this average is not a reasonable approximation of the
cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the dates of the transactions); and
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | all resulting exchange differences are recognised in other comprehensive income.
|- |  | --------------------------------------------------------------------------------

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and
translated at the closing rate. Exchange differences arising are recognised in equity.

(iii) Foreign Currency Transactions

Transactions in foreign currencies are recorded at the rate of exchange prevailing on the transaction date. Gains and losses on foreign currency resulting from the settlement of such transactions and from
the conversion at the closing exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except when deferred in other comprehensive income as qualifyng cash flow hedges.



|f) | Cash and cash equivalents
|-- | -------------------------

Cash and cash
equivalents include cash-in-hand, deposits held on call at banks and other liquid investments with an original maturity of less than three months.



|g) | Financial Instruments
|-- | ---------------------

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

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

Derivatives are also classified as acquired for trading unless they are designated as hedges. Assets in this category are classified as current assets
and the obligation for these instruments is presented under Other Financial Liabilities within the Financial Statement.

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

The
financial assets and liabilities carried at fair value through profit or loss are initially recognized at fair value and transaction costs are expensed in the income statement. They are subsequently recorded at fair value with the effect of the
change in value recorded in income.

Swaps: These are valued using the discounted cash flow method at a discount rate consistent with the risk
of the operation.

Forwards: These instruments are initially recognized at fair value at the date on which the contract is entered into and
are subsequently re-measured at fair value. The forwards are recorded as assets when fair value is positive and, as liabilities when fair value is negative.

The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles.

The fair value of forward rate contracts is calculated by reference to differential of the existing interest rates between the rate agreed and the market
interest rate deadlines.

Mutual Funds: Given their nature, they are recognized at fair value at the closing date for the period.

The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles.

(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. They are included in current assets, except for maturities greater
than 12 months from the balance sheet date, which are classified as non-current assets. Loans and receivables include trade receivables and other receivables.

Loans and receivables are initially recorded at fair value and subsequently at amortized cost according to the effective interest rate method. A provision of bad debts is recorded to reflect uncollectable
amounts.

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

Repurchased Agreements: These are valued at the initial cost of the investment plus accrued interest investment
cost of the short term instrument.

(iii) Financial liabilities valued at amortized cost

Loans, bond obligations and liabilities of a similar nature are recognized initially at fair value, net of transaction costs incurred. In subsequent
periods, they are stated at amortized cost and any difference between proceeds (net of transaction costs), and redemption value is recognized in the income statement over the life of the debt according to the effective interest rate method.

Financial obligations are classified as current liabilities unless the Company has an unconditional right to defer settlement for at least 12
months after the balance sheet date.

The fair value estimate of bank obligations is determined using specific valuation techniques using cash
flow discounted at rates consistent with the risk of the operation, while bonds are valued at market price.

(iv) Creditors and other payables

These instruments are initially recorded at fair value and subsequently 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 cash flow hedges is recognized in the Comprehensive Income Statement. The gain or loss relating to the ineffective portion is recognized immediately in
the Income Statement within Other Operating Income by activity or Operating Expenses by activity, respectively.

When a hedging instrument
expires or is sold, or when it ceases to meet the criteria to be recognized through the hedge accounting treatment, any cumulative gain or loss in equity at that time recognized in the Income Statement. When a possible transaction is no longer
expected to occur, the cumulative gain or loss in equity is immediately transferred to the Income Statement.

These financial instruments are measured using the discount cash flow method at a rate consistent with
the operational risk using the information given by each bank as counterparty.



|h) | Inventories
|-- | -----------

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

The cost of finished goods and work in
progress includes the cost of raw materials, direct labor, other direct costs and general manufacturing 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 manufacturing costs of a product exceeding its net realizable value, a valuation allowance is made. This provision
also includes obsolescence amounts resulting from slow moving inventories and technical obsolescence.

Replacement parts that will be consumed
in less than a period of 12 months, are presented in Inventories and record as an expense within the period consumed.



|i) | Assets held for sale
|-- | --------------------

Non-current assets
held for sale are measured at the lower of book and fair value, less costs for sale. Assets are classified in this line when the book value may be recovered through a sale transaction that is highly likely to be carried out. Management must be
committed to a plan to sell the asset and should have initiated an active program to find a buyer and complete the plan. Likewise, management must also expect that the sale will be qualified for full recognition within one year following the date of
its classification, except for the existence of facts or circumstances (beyond the entity control) that extend the period of sale beyond one year.

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



|j) | Business Combinations
|-- | ---------------------

Arauco applies the
purchase method to record a business combination. Acquisition cost is the fair value of assets delivered, of equity instruments issued and of the liabilities incurred or committed at the date of exchange, plus all direct costs attributable to the
acquisition. Identifiable acquired assets and liabilities as well as the contingencies committed to in business combinations are initially recognized at fair value at the date of acquisition, despite minority interest scope. Excess of acquisition
cost over the Fair Value of the Companys share of the identifiable net assets acquired is recorded as goodwill. If this is less than Fair Value of the net assets of the subsidiary acquired, the difference is recognized directly in the
statement of income.

The goodwill in a business combination is initially measured at the cost of the business combination less the interest
of the company in the net fair value of identifiable assets, liabilities and contingent liabilities of the acquisition. 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 without prejudice to whether other assets or liabilities of Arauco are assigned to those units or groups of units.

The transaction costs are treated as expenses when incurred.

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.



|k) | Investments in associates and in joint ventures
|-- | -----------------------------------------------

Associates are entities over which Arauco exercises significant influence but not control, generally holding between 20% and 50% of the voting rights. Investments in associates and in joint ventures are
accounted for using the equity method and are initially recognized at cost. Their book net equity is increased or decreased proportionately in the profit or loss and comprehensive income statement of the period as a result of adjustments of
conversion arising from the financial statement conversion into other currencies. Araucos investment in associates includes goodwill (net of any accumulated impairment loss).

If the cost of acquisition is less than the fair value of the net assets of the associate acquired, the difference is recognized directly in the income statement as Other income (loss).

These investments are presented in the Consolidated Balance Sheet together with Investments in associates and measured by using the equity method.

If any of these investments incurs negative equity as a result of legal or implicit obligations of its associate, or has made payments on
behalf of its associate or joint venture, then it must recognize a liability by reducing the value of the investment to zero until this generates income that would reverse the negative equity previously generated due to the losses. Otherwise, a
liability is not recognized but the investment left at zero equally.



|l) | Intangible assets
|-- | -----------------

After initial
recognition, intangible assets are carried at cost, including any accumulated amortization and impairment losses.

Amortization of an
intangible asset with a finite useful life shall be carried on a systematic basis over the assets useful life. Amortization begins when the asset is available for use, which is when it complies with all the necessary conditions to operate in
the manner foreseen by the Company.

(i) Computer Software

Computer software programs are capitalized in terms of the costs incurred to make them compatible with specific programs. These costs are amortized over the estimated useful lives.

(ii) Rights

This item includes water-rights,
right of way and other acquired rights recognized at historical cost and have an unlimited useful life as the expected cash flow generating period is unpredictable. These rights are not amortized as they are perpetual and will not require renewal,
but are subject to annual impairment tests.

|m) | Goodwill
|-- | --------

The excess of the cost of
acquisition over the fair value of the groups share of the identifiable net assets acquired is recorded as goodwill. Goodwill is not amortized but is tested for impairment on annual basis.

The goodwill recorded in Brazilian subsidiary whose functional currency is the real, is converted to U.S. dollars at the closing exchange rate. At the
date of these financial statements, the currency conversion is the only movement that has the amount of goodwill.



|n) | Property, Plant and Equipment
|-- | -----------------------------

Property,
plant and equipment are stated at historical cost less depreciation and accumulated impairment losses. Historical cost includes expenditures that are directly attributable to the acquisition.

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 the group and the cost of the item can be measured reliably. The value of the replaced part is capitalized as part of the property, plant & equipment, the remaining part which
corresponds to repairs and maintenance are charged to the income statement.

Asset depreciation is calculated by components using the
straight-line method, considering any adjustments for impairment.

The useful life of property, plant and equipment is determined according to
expected use of the assets.

The assets residual values and useful lives are reviewed, and adjusted if appropriate, on an annual basis.



|o) | Leases
|-- | ------

Fixed asset leases in which
Arauco substantially holds all ownership risks and advantages are classified as Financial Leases. Financial leases are capitalized at the leases commencement at the lower of the fair value of the leased property and the present value of the
minimum lease payments.

When assets are leased under finance lease, the present value of lease payments is recognized as a financial account
receivables. Interest income which is the difference between the gross receivable and the present value of such amount is recognized as the capitals financial performance.

Leases in which significant 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
charged to the income statement on a straight-line basis over the period of the lease.



|p) | Biological Assets
|-- | -----------------

IAS 41 requires that
biological assets, such as standing trees, are presented in the Balance Sheet at fair value. The forests are thus accounted for at fair value less estimated point-of sale costs at harvest, assuming that the fair value of these assets can be measured
reliably.

##### Table of Contents

The valuation of forest plantation assets is based on discounted cash flow models whereby the fair value
of the biological assets is calculated using cash flows from continuous operations, which are discounted based on our sustainable forest management plans and the estimated growth of the forests. This valuation is performed on the basis of each
identifiable farm block basis and for each type of tree.

The assessment of new plantations during the current year, is made at the least
economic cost, which corresponds to the fair value to that date. After 12 months, the valuation methodology isi as explained in the previous paragraph.

Forest plantations shown as current assets are those that will be harvested in the short term.

Biological growth and changes in fair value are recognized in the income statement within Other income by activity.

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



|q) | Deferred income tax
|-- | -------------------

Deferred income tax
is recognized using the 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 as of the balance sheet date that are expected to apply when the related deferred income tax asset or the deferred income tax liability is settled.

The deferred income tax assets are recognized to the extent that it is probable that future taxable benefits will be available.



|r) | Provisions
|-- | ----------

Provisions are recognized
when the Company has a current legal or constructive obligation as a result of past events; it is probable that an outflow will be required to settle the obligation; and the amount has been reliably estimated. This amount is quantified and
recognized with the best possible estimate at the end of each period.



|s) | Revenue recognition
|-- | -------------------

Revenues are
recognized after Arauco has transferred the risks and rewards of ownership to the buyer and Arauco retains neither a continuing right to dispose of the goods, nor effective control of those goods; this means that generally revenues are recorded upon
delivery of goods to customers in accordance with agreed terms of delivery.

(i) Policy on Revenue recognition from the Sale
of Goods

Revenue from the sale of goods is recognized when an Arauco entity has transferred to the buyer the significant risks and rewards of
ownership, when the amount of revenue can be reliably measured, when Arauco cannot influence the management of the sold goods and when it is probable that the economic benefits associated with the transaction will flow to the entity.

Sales are recognized in terms of the arranged price stated in the sales contract, net of volume
discounts and estimated refunds 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 for sales are collected within a low average time
period, which is in line with market practices.

(ii) Policy on Revenue recognition from Rendering of Services

Arauco, mainly provides power supply services which are trade in the spot market of the Interconnected Central System. According current laws, the
prices on that market called Marginal Costs are calculated by Load Economical Dispatch Center of the Interconnected Central System (CDEC-SIC). And are generally recognized in the period in which the services are provided.

Electrical energy is generated as a by-product of the pulp process and is a complementary business to it, which at first is supplied to the
groups subsidiaries and the surplus is sold to the central grid.

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

Segment revenues mentioned in Note 24 comply with the conditions indicated above.

Revenues from
inter-segment sales (arising from prices similar to market prices) are eliminated in the consolidated financial statements.



|t) | Minimum dividend
|-- | ----------------

Article No. 79 of
the Private Limited Companies Law of Chile provides that, unless otherwise unanimously agreed or adopted by the shareholders, a dividend must be distributed annually in cash to shareholders in proportion to their shares or in the proportion
established by the statutes for preferred shares, if any, in the amount of at least 30% of net income for the current year, except where necessary to absorb accumulated losses from prior years.

The General Shareholders Meeting of Arauco resolved to maintain annual dividends at 40% of net distributable income, including a provisional
dividend share distribution at year-end. Dividends payable are recognized as a liability in the financial statements in the period they are declared and approved by the Companys shareholders or when configuring the corresponding obligation on
the basis of existing legislation or distribution policies established by the Shareholders Meeting.

The interim and final dividends are
recorded in equity upon their approval by the relevant groups, which include the Companys Board and the shareholders.

The amount of
these dividends is presented in this consolidated financial statement under Other non-current Financial Liabilities.

Dividends are paid only
if profits in society and do not affect taxes.

|u) | Impairment
|-- | ----------

Non-financial Assets

The recoverable amount of property, plant and equipment is measured whenever there is an indication that the asset may have suffered
deterioration of its value. Among the factors to consider as evidence of impairment are the diminution in market value of assets, significant changes in the technological environment, obsolescence or physical impairment of assets and changes in the
way the asset is used or expected to be used (which could involve its disuse). Arauco evaluates at the end of each reporting period whether there is any evidence of the factors above mentioned.

For this evaluation, assets are grouped into the smallest group of assets that generates cash inflows independently.

The goodwill and intangible assets with indefinite useful life are tested annually or whenever circumstances indicate. The recoverable amount of an asset
is estimated as the higher of net selling price and value in use. An impairment loss is recognized whenever the carrying amount exceeds the recoverable amount.

A previously recognized impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount, however, not to an extent higher than the carrying amount that
would have been determined and recognized in prior years. For goodwill, however, a recognized impairment loss is not reversed.

Goodwill is
allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating units or groups of cash-generating units that are expected to benefit from the business combination in which the goodwill
arose.

Cash-generating units are the smallest identifiable groups of assets whose use generates continuous funds largely
independent of those produced by the use of other assets or groups of assets.

Goodwill is allocated to cash-generating units for the purpose
of impairment testing. The distribution is made between cash-generating units or groups of cash generating units expected to benefit from the business combination that resulted in the goodwill.

Financial Assets

At the end of each
period, an evaluation is performed in order to measure the existence of any objective evidence that assets or a group of financial assets have been adversely affected. Impairment effects will be recognized in the Consolidated Income Statement only
if there is objective evidence that one or more events will occur after initial recognition of financial asset impairment and if these events will affect associated future cash flows.

The provision for doubtful trade receivables is established when there is objective 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, and are written-off when Arauco has exhausted all levels of recovery of debt in a reasonable time.

The impairment loss is measured as the difference between the book value of assets and the current value of estimated future cash flows. The asset value will be presented net of the loss recognized
directly in income. If the impairment loss decreases in later periods, it is reversed either directly or by adjusting the provision for doubtful accounts, with effect in income.

|v) | Employee Benefits
|-- | -----------------

The Company has
severance payment obligations for voluntary cessation services. These are paid to certain workers that have more than 5 years seniority within the Company in accordance with conditions established within collective or individual 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.

The main
factors considered for calculating the actuarial value of severance payments 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 income in the year they are incurred.

These obligations are treated as post-employment benefits in accordance with current standards.



|w) | Employee Vacations
|-- | ------------------

Arauco recognizes the
expense for employee vacation on an accrual basis and it is recorded at face value.

This obligation is presented in the Consolidated Balance
Sheet in the line Trade and Other payables.

|IFRS 1 |  | First-time Adoption of International Financial Reporting Standards Issued in December 2010, covers the following topics: i) Exemption for severe hyperinflation: allows companies
whose transition date is after the normalization of its functional currency, valuing assets and liabilities at fair value as deemed cost, ii) Removal of requirements for fixed dates: adapts the fixed date included in IFRS 1 at the transition date
for those operations that involve lower financial assets and liabilities at fair value on initial recognition results. |  | July 01, 2011

Arauco believes that the adoption of standards, amendments and interpretations described above will have no significant
impact on the financial statements of the Company in the period of initial application.

|NOTE 5. | ACCOUNTING POLICIES, CHANGES IN ACCOUNTING ESTIMATES
|------- | ----------------------------------------------------

Changes in Accounting Policies

These policies have been designed in accordance with IFRS
in effect as of December 31, 2011 and applied uniformly to all items presented in these consolidated financial statements.

Changes in
the Treatment of Accounting Policy

The financial statements as of December 31, 2011 do not show changes in accounting policies
compared to the same period last year.



|NOTE 6. | TAXES
|------- | -----

The tax rate applicable to the
major companies in which Arauco participates is 20% in Chile, 35% in Argentina and 34% in Brazil.

On July 30, 2010 Law N. 20,455 for
national reconstruction financing was published in the Chilean Official Gazette (Diario Oficial de Chile). One of the most important changes such law introduced was the increase in the First Category Taxes for revenues received and /or accrued
during commercial years 2011 and 2012, with rates of 20% and 18.5%, respectively.

The effect on the change in tax rates caused an adjustment
to the assets and liabilities accounts for deferred taxes, according to the profile projected for temporary reverse differences, in tax losses benefits and in other events that create differences between book and tax basis of assets and liabilities.

The effect of deferred taxes related to financial hedging instruments corresponds to a credit
(subscription) of ThU.S.$ 932 as of December 31, 2011 (ThU.S.$1,896 as of December 31, 2010), which is presented under Hedge reserves in the Statement of Changes in Net Equity.

From the deferred tax assets and deferred tax liabilities listed in the above tables, approximately ThU.S.$17,635 and ThU.S.$74,689 respectively, will be used in a period of 12 months.

Arauco does not offset deferred tax assets and deferred tax liabilities since there is no legal right to offset amounts recognized in these items that
correspond to different fiscal jurisdictions.

Description of Property, Plant and Equipment Pledged as Guarantee

Regarding Forestal Río Grande S.A, an affiliate of Fondo de Inversión Bío Bío, a special purpose entity, we note that in
October 2006, first and second degree mortgages were executed in favor of JPMorgan Chase Bank N.A. and Arauco, respectively, which prohibited the sale of any property currently belonging to the aforementioned special purpose entity, in order to
ensure fulfillment of payments to Fondo de Inversión Bío Bío.

In September 2007, Forestal Río Grande S.A acquired
real estate in Yungay, located in Chiles Region VIII, for which the company executed a first mortgage with prohibition to sell and encumber in favor of, among others, JPMorgan. Similarly, a second mortgage with prohibition to sell and encumber
was executed in favor of Arauco.

|NOTE 15. | INVESTMENTS IN ASSOCIATES
|-------- | -------------------------

On
December 21, 2011, Arauco made a ThU.S.$ 3,302 contribution of capital to the company Puerto de Lirquen S.A. As a result, at the end of 2011, Arauco held 20.20 % of the capital of such company.

On December 14, 2011, was made a capital contribution of ThU.S.$5,004 to Inversiones Puerto Coronel S.A. This contribution did not change the
percentage of participation in this company.

On November 17, 2011, our subsidiary Arauco Forest Brazil S.A., made a contribution of
ThU.S.$232,916 to the Brazilian company Centaurus Holding S.A., representing an ownership interest of 43.05%. This investment was conducted in conjunction with Klabin S.A., one of the most important companies in the forestry sector located in
Brazil.

In November 2011, Centaurus Holding S.A. acquired 100% of the voting rights of the brazilian company Florestal Vale do Corisco
Ltda., a company that owns 107,000 hectares in the State of Parana. This transaction strengthens the position of Arauco in the forestry sector in Brazil for the development of its industrial operations and ensures the supply of wood of future
projects. Further this transaction had no impact on the results of Arauco.

On March 29, 2011 Novo Oeste Gestao de Ativos Florestais S.A.
was incorporated, receiving a capital contribution from our subsidiary Arauco Forest Brasil S.A. of ThReal$1,225 in exchange for 1,225,000 shares representing 48.9912% of ownership. The corporate purpose of this company is the management of forestry
assets and commercialization of wood.

On February 2, March 12, May 10 and July 9, 2010 capital contributions in
an amount equal to ThU.S.$2,000 each, were made to the associated company Inversiones Puerto Coronel S.A. These contributions of capital do not modify the percentage of participation in this associate.

The information operations have no effect on the consolidated financial statements.

Realized
Investments

In August and December of 2011, the Dutch subsidiary Arauco Holanda Cooperatief U.A. made contributions of ThU.S.$138,904 to
the associated Celulosa y Energía Punta Pereira S.A. (Uruguay), obtaining a 38.09% of participation rate. Result of this contribution, Inversiones Arauco Internacional Ltda. which made contributions of ThU.S.$21,993 in 2011, decreased its
participation to a 11.91%, remaining Arauco Group with 50 % control of the Joint Venture.

This operation have no effect on the
consolidated financial statements.

Investments in Uruguay

The main assets acquired from Ence during the year 2009 are: 130,000 hectares of land (of which 73,000 hectares are forestry plantations and 6,000 hectares are 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 nursery.

All these assets were added to the land and plantations that Stora Enso and Arauco control through a joint venture in Uruguay, which currently maintains forestry equity of approximately 265 thousand
hectares of land, of which 149 thousand hectares are planted.

During 2010, Arauco made contributions to companies in Uruguay amounting
to ThU.S.$39,559. In 2011, Arauco made capital contributions to these companies for a total of ThU.S.$.177,397, in order to carry out the Montes del Plata project having received Stora Ensos commitment to build a state of the art
pulp mill with a guaranteed annual capacity of 1.3 million tons, a dock and a power plant that generates energy from renewable sources in Punta Pereira, an area located in the Colonia department in Uruguay.

The investments in Uruguay mentioned above qualify as joint ventures because of existing contracts that stipulate that both Arauco and Stora Enso
maintain joint control of such investments.

Furthermore, Arauco holds a 50% share in Eka Chile S.A. (Eka), a company that sells
sodium chlorate to cellulose plants in Chile. A contractual agreement in effect between and Arauco and this company has permitted Arauco and Eka to initiate certain joint venture activities.

|NOTE 17. | IMPAIRMENT OF ASSETS
|-------- | --------------------

At the end of this
accounting period, we had the following information:

Effects from the economic crisis

The decrease in demand for sawn timber products due primarily to the credit crisis and the continued downturn in the real estate market in the United
States have led Arauco to decide to permanently close during the fiscal year 2009 and 2008, and during first months of 2010 Arauco had stopped activities of the following sawmills: La Araucana, Escuadrón, Lomas Coloradas, Coronel, Coelemu,
Horcones II, and the remanufacturing plant Lomas Coloradas. All closed facilities are located in Chile.

During May 2010, Horcones II plant
restarted operations and in June 2010 the Plant of Coronel was sold. By the continuing investment in equipments and technologies and more intensive use of our facilities, an important part of the production capacity of the plants have been supplied,
and determined that the closure of Araucana, Escuadron, Aserradero Lomas Coloradas, Coelemu sawmills and Lomas Coloradas remanufacturing plant is considered as permanent. As of the closing date of these Consolidated Financial Statements, the assets
associated with these plants located in Chile are classified as Assets held for sale, as mentioned in Note 22.

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
using its land and buildings as a logistics center. At the end of 2010, the Company registered ThU.S.$2,000 as impairment provision related to machinery and installations which at the end of 2011 have a value of ThU.S.$1,500 (after discounting the
provision). To date, the Company is working on classification and management of these assets to have the approval of the administration for its subsequent sale.

The recoverable value of the permanently closed facilities was determined based on sales estimates and residual value, making the corresponding provision in the event that the recoverable value is less
than the book value. These estimates were made by both external and internal evaluators.

Effects from the earthquake

Immediately after the earthquake that impacted the southern central region of Chile on February 27, 2010, an area in which the Company maintains its
industrial operations, all of our production units applied their contingency plans. This involved shutting down operations and evaluating the damage caused to each facility by the earthquake.

Mutrún sawmill located in Constitución was destroyed by floodwaters. This facility represented a 6% of the Arauco saw timber production capacity in Chile.

Araucos industrial facilities, 34 in Chile, have resumed their activities in the shortest time possible. As of the date of this Financial
Statement, all of its facilities are operating including line II of the Arauco Pulp Mill from February, 2011.

Damages caused by the earthquake were adequately covered by the following insurance policies:



| |  |  | All risk of physical assets and income (loss)
| | - |  | ---------------------------------------------



| |  |  | All transport risk and all inventory losses
| | - |  | -------------------------------------------



| |  |  | Residential Fire
| | - |  | ----------------



| |  |  | All construction risk
| | - |  | ---------------------

These Consolidated Financial Statements reflect the receipt by Arauco of insurance payments in respect of claims for damage that arose from the
earthquake and tsunami occurred on February 27, 2010. In 2011, these payments amounted to U.S.$254 million (U.S.$285 million in 2010). Araucos aggregate recovery was U.S.$539 million as of 31, December 2011 (of which U.S.$211 million
corresponds to physical damages and U.S.$328 million are attributed to the losses arising from the stoppage of activities), which is the total and final compensation to be received by Arauco as settled with the insurance companies.

Related expenses to the damage produced by the earthquake were recognized when the relevant events occurred, but accounts receivable from insurance
companies related to these expenses, in addition to the closure of the plant as a result of the earthquake, were recognized only when there was sufficient supporting documentation and /or at the time of the reception of the cash flows.

Other effects

In December 2011,
particle board (PBO) lines of Curitiba Plant (Brasil) were shut down due to the high cost of maintainance, with the consequential losses that this generated. The company registered ThU.S.$6,088 as impairment provision related to machinery and
equipments.

Cash-Generating Unit with Impaired Assets

Information on Impaired Assets as of December 31, 2011 amounted to ThU.S.$2,000 by closing of Bossseti sawmill located in Argentina, and amounted to ThU.S.$6,088 by closing lines of Curitiba Plant.

At the date of these financial statements has reversed the most of the associated impairment provision of physical damage
of property, plant and equipment product of earthquake and tsunami. The amount of the existing provision is referred to assets that are in the process of repair and / or replacement, the majority concluded at the end of 2011.

Goodwill

Goodwill is allocated to the
groups of cash-generating units that generate such goodwill. The goodwill generated by the investment in Arauco do Brazil (formerly Tafisa) was assigned 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 projected cash flows based on the operational plan approved by the management covering a period of 10 years, 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, 2011 this goodwill amounted to ThU.S.$56,267 (ThU.S.$63,374 at December 31, 2010). The variation is due only to the conversion adjustment to Real,
which is the functional currency for the subsidiaries in Brazil, therefore, there has been no impairment provision.

|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:

1. On October 8, 2007, the Federal Administration of Public Income (Administración
Federal de Ingresos Públicos) (AFIP) initiated an ex oficio procedure against the Company 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 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, which includes the principal amount owed, interest and fines.

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.$1,369 at December 31, 2011).

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 precautionary measures.

On May 13, 2010 the Federal Appeal Court decided to accept the precautionary ruling requested by APSA, ordering to suspend the enforcement of the
AFIP resolution until the final decision on this matter. This precautionary ruling was granted by the Federal Appeal Court subject to the granting of a corresponding bond. On May 19, 2010, APSA filed with the Appeal Court a surety policy issued
by Zurich Argentina Cía. de Seguros S.A. After some precisions made by APSA on the abovementioned policy, on June 2, 2010, the Federal Appeal Court accepted this surety filed by APSA and ordered to notify the precautionary ruling granted
to the AFIP. On June 4, 2010 the AFIP was notified on this precautionary ruling, which is final since June 22, 2010.

In spite of the TFNs ruling, the opinion issued by APSAs external counsel continued to be
that APSA has proceeded in a lawful manner in deducting the amount questioned by the State. External counsel maintains that there is a good chance that the TFNs ruling will be overruled and that the AFIPs ex-oficio decision will be
rendered without effect. Due to the above, no provisions have been recognized for the periods in which the Negotiable Obligations were in force.

(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.$2,430 at December 31, 2011) 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$380 at December 31, 2011), 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 fileds before the Court. On July, 14, 2011 the AFIP answered the petition of this brief. On
October 7, 2011 a brief was presented stating the interest of solving the cause. Based on their analysis of the grounds underlying the appeal, APSAs counsel has an optimistic view of the case.

2. With regard to the Valdivia Mill, on April 27, 2005, the National Defense Council (Consejo de Defensa del Estado) filed a civil lawsuit against
the Company for reparation of environmental harm and indemnification 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 Companys position. On September 5th, 2011, objections were submitted against said expert reports. The Court carried out a personal examination of the site on
March 13, 14 and 15 of 2012. At the same time, ancillary proceedings are still pending in respect of the technical reports filed by the company in support of its objections against the expert reports.

3. With regard to the Nueva Aldea Mill, on December 21, 2007, the Company was notified of nine similar complaints. Eight complaints are
directed against Echeverría Izquierdo Montajes Industriales S.A., as employer, and against Arauco, as jointly responsible, and also against the Company directly. The other complaint is directed against Mr. Leonel Enrique Espinoza
Canales, as employer, against Arauco, as jointly responsible, and also against Arauco directly.

The complaints request that all plaintiffs
(72 plaintiffs in total) be indemnified for the damages that they allegedly suffered as a result of an accident in which three persons working for the contractor Echeverría Izquierdo Montajes Industriales S.A. were allegedly involved. This
contractor was undertaking construction work at the Nueva Aldea Pulp Mill in December 2005.

These three workers allegedly suffered
irradiation from handling certain equipment and materials belonging to a subcontractor of Echeverría Izquierdo Montajes Industriales, S.A. After being notified of these complaints, the Company opposed them on the basis of lack of

jurisdiction, and, answered the principal complaints, arguing that they are invalid for failure to state a claim. The Company also responded to the secondary complaints made directly against the
Company, requesting that they be rejected for lacking any merit. All these demands have been consolidated into a single action, for which a trial is currently underway. On March 23, 2011, Echeverría Izquierdo Montajes Industriales S.A.
terminated all proceedings through out-of-court settlements with the plaintiffs, without acknowledging its liability. As a result, it waived all of its rights against the former as well as the other defendants, Leonel Espinosa Canales and Celulosa
Arauco y Constitución S.A. On March 24, 2011, the settlement was submitted to the court for their approval. On April 27, 2011 the court approved the settlement.

Based on these same events, on November 10, 2009, the Company was notified of a labor complaint, pursuant to a general application procedure initiated by 14 ex-employees of Echeverría
Izquierdo Montajes Industriales S.A. construction company, against the latter as a principal complaint, and against Arauco as jointly responsible, based on emotional distress suffered due to alleged exposure to a radioactive isotope during the
accident that occurred in Planta Nueva Aldea on December 14 and 15, 2005. The Court denied the complaint based on the applicable statute of limitation. This case has been terminated through the abovementioned settlement. To date the withdrawal
es approved and the cause is filed and closed.

Based on these same events, on January 29, 2008, the Company was notified of an action
for damages due to a work accident filed by Mr. Fernando Vargas Llanos, against his former employer Inspección Técnica y Control de Calidad Limitada (ITC), the construction company Echeverría Izquierdo Montajes Industriales
S.A. and against the Company. The complaint requests that Mr. Vargas be indemnified for the damages that he allegedly suffered as a result of the events that took place in December 2005.

Notified of said complaint, the Company opposed it on the basis of lack of jurisdiction, and, answered the principal complaint stating that it should be dismissed for lacking any merit. On July 20,
2009 the Court dismissed the complaint on the grounds that the plaintiff had ceased in his procedural activity for more than six months, which was then challenged by the plaintiff. The Appeals Court subsequently overruled the dismissal, rejecting
the lower courts argument of abandonment. Therefore, the processing of this case, was resumed, and a hearing was set for conciliation and testing on January 25, 2011. The hearing was not held on the mentioned date. The court was on
setting new date and time. This is the only case that continues pending.

4. 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 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.

5. Regarding Licancel plant, on June 22, 2011 the Company was notified by
rogatory letter of a action seeking damages 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 malaquito river on June 5, 2007. The plaintiffs seek to be compensated for alleged damages that they have suffered from the aforementioned event, including lost profits, pain and suffering and an alleged
contractual liability. On January 30, 2011 the plaintiffs requested that was decided statement of evidence. On January 2, 2012, the court provided Documents-auto case pending of issued statement of evidence.

6. On April 14, 2009, Forestal Celco S.A. was notified of a civil lawsuit filed by Mario Felipe Rojas Sepúlveda on behalf of Víctor
Adrián Gavilán Villarroel against Cooperativa Eléctrica de Chillán Limitada and against Forestal Celco S.A. The lawsuit aims to make both companies jointly and severally liable for compensation of alleged material damages
suffered as a result of a fire that occurred on January 12, 2007 on the El Tablón county property, which belongs to Forestal Celco S.A.

On April 30, 2009 Forestal Celco S.A. filed objections pointing to defects in the demand. The plaintiff rectified the defects, and the Company replied to the demand. On March 8, 2011 the Court
issued the legal judgment of first instance rejecting the claim. On March 21, 2011, the plaintiff appealed against the first instance verdict. The case is currently under review by the Chillan Court.

7. On December 1, 2007, Forestal Celco S.A. was notified of a civil lawsuit filed by Marcela Larraín Novoa on behalf of Nimia del Carmen
Alvarez Delgado against Patricia del Carmen Muñoz Zamorano and Forestal Celco S.A. This lawsuit seeks to reclaim an 88% share of the rights to the Loma Angosta property, which has a surface area of 281.89 hectares. This property
was purchased by Forestal Celco S.A. from Patricia del Carmen Muñoz Zamorano in 1994. To date, Patricia del Carmen Muñoz Zamorano has not yet been notified of this action.

As a result on May 18, 2008, the Company filed a motion to correct the claim, which was allowed and accepted by the Court. As of this date, the plaintiff has not corrected the defects of its claim
finding the case pending.

8. On January 26, 2011, Forestal Celco S.A. was notified of a civil claim submitted by Mr. Hans Fritz
Muller Knoop against Cooperativa Eléctrica de Chillán Limitada and Forestal Celco S.A., which seeks that both companies be condemned to pay (jointly and severally) an indemnity for the alleged material damages caused as a result of the
spreading of a fire on January 12th, 2007, in the estate named El Tablon, owned by Forestal Celco S.A.

On March 10,
2011, Forestal Celco S.A. answered the claim. As of December 28, 2011 began the trial period, ending on January 20, 2012, still some experts reports remain pending.

9. On September 26, 2005, in proceedings numbered 48,679-2006 of the Civil Court of Constitución, Forestal Celco S.A. submitted a claim against Forestal Constitución Ltda. and Vitelia
Morán Sepúlveda and other 7 natural persons, with the goal of obtaining a ruling that acknowledges its sole ownership over the Lierecillo estate (1,126 hectares), formed by various property registrations, also seeking that the
defendants be sentenced to jointly and severally pay $20,000,000 as well as a damage compensation for having harvested a portion of the aforementioned estate. On April 23, 2006, Mr. Adolfo Numi Velasco, acting on

behalf of all the aforementioned natural persons, answered the claim requesting its rejection, arguing that his clients are the sole owners of the estate named El Macaco, also
submitting a counterclaim with the purpose of demanding that Forestal Celco S.A. return the El Macaco estate, of 162.7 hectares plus a damage compensation for the resulting damages, loss of profit and moral damage. On June 29, 2009,
a first instance ruling was issued in favor of Forestal Celco S.As claim, only with regards to the declaration of ownership, rejecting all other aspects of that claim as well as the corresponding counterclaim. Currently, the case is being
processed by the Court of Appeals of Talca, under court registration number 267-2002, currently awaiting the conduction of closing arguments and the issuance of a ruling regarding the appeal submitted by the defendant, which also has the condition
of counterclaiming plaintiff.

10. On September 23, 2008, 28 workers submitted a lawsuit against their employer, Gama
Services (which rendered services for Bosques Arauco S.A.subsidiary of Celulosa Arauco y Constitución S.A.), and Bosques Arauco S.A., for an alleged joint and several liability, requesting that the termination of their labor agreements be
declared unjustified, demanding for the full payment of their social security and health benefits as well as the payment of severance for their years of service, dismissal notice, vacations, remunerations and extra hours. Said lawsuit was submitted
before the 5thLabor Court of Santiago, under Docket
number 780-2008, with an undetermined claimed amount.

On January 4, 2011, Bosques Arauco S.A. received the notice of the definitive
first instance ruling against Gama Services, ordering the payment of all claimed compensations, including remuneration and social security and health benefits, until the validation of the dismissal or until the ruling has been executed.
Simultaneously, the ruling joint and severally condemns the Company to pay various compensations including social security payments - that are calculated until the day of the dismissal. The lawsuit is concluded with a second-degree decision
issued in favor of the plaintiffs. As of this date, the credit arising from said decision is still pending liquidation.

11. On
November 17, 2003, Bosques Arauco S.A., an affiliate of Celulosa Arauco y Constitución S.A., was notified of a property restitution claim brought by Ms. Celmira Maria Curin Tromo, whom requested the restitution of certain real
estate, its profits and damages in a Special Indigenous Lawsuit, claiming that she is the sole and exclusive owner of the 5.5 hectares of land, which has allegedly been exploited by Bosques Arauco S.A., in blatant disregard of her property interest.
On June 6, 2008, the first instance decision was issued, denying the claim. The decision was appealed and the Ilustrísima Corte de Apelaciones de Temuco (High Court of Appeals of Temuco) overturned the decision on January 6, 2009,
finding in favor of the plaintiff with regard to every portion of the claim and ordering the restitution of the land, along with all profits and damages caused by Bosques Arauco S.A. to the land, the assessment of which was deferred to the
decisions execution phase.

On October 28, 2009, the plaintiff requested the execution of the ruling with notice to the defendant.
Aside from the restitution of the property and its products, the plaintiff also requested damages for the pain and suffering she had allegedly personally endured. After being notified of the request, Bosques Arauco S.A., in turn, requested that this
request be nullified on the ground that the alleged pain and suffering was not an issue in the judicial proceedings and, hence, that the ruling should not include any such damages.

12. On April 29, 2004, Aserraderos Arauco S.A. was served a breach of contract plus damages claim filed by Ingeniería y
Construcciones Ralco Ltda. This claim was submitted before the 2ndCivil Court of Concepción, Docket number 3218-2003.

The plaintiff argues that the
contracts entered into with sawmill administrators have an effect over Aserradores Arauco S.A.

In this suit, the evidentiary ruling was issued, but it has not yet been notified. There have been no
actions for over a year and it is currently archived.

13. On December 12, 2010, the company Sociedad Forestal
Cholguán S.A. was notified of a boundaries and site fencing claim, submitted by Banfactor Servicios Financieros Limitadas Receiver before the 30thCivil Court of Santiago, file number 12.825-2010, labeled Banfactor Servicios Financieros Limitada and Forestal
Cholguán S.A., which seeks to set the boundaries and site fencing between the neighboring property owned by Forestal Cholguán S.A., named Hacienda Canteras, and a estate named Fundo Roma. An expert determined that
there is not any land adjoining called Fundo Roma, finding Hacienda Canteras perimeter closed and demarcated for many years. Currently, the process is in a fault condition, awaiting that the expert appointed by the Court submits his/her
report. Within the context of these same proceedings, on December, 2010, the Court issued a cautionary injunctive measure prohibiting the execution of acts or agreements regarding the lumber and forest products located within Fundo Roma.
On April 3, 2012, the Court issued a ruling rejecting the claim, and the term for appealing such ruling is still pending. On April 13, 2012, Forestal Cholguán S.A. filed a request to revoke the injunction, request which is still
pending.

14. 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

with respect to APSAs export proceeds. APSA responded to the charges in a timely and correct manner.

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.

At December 31, 2011 and the date of issue of these financial statements there are no changes to
the legal situation of the matters mentioned in the preceding paragraphs and included in the financial statements at December 31, 2010, so that no additional provisions registered at that date.

|NOTE 20. | BIOLOGICAL ASSETS
|-------- | -----------------

Araucos
biological assets are its forestry plantations of mainly radiata and taeda pine and a lesser degree of eucalyptus. The total plantation is distributed in Chile, Argentina, and Brazil, reaching 1.6 million hectares, of which 980 thousand hectares are
used for forestry planting, 405 thousand hectares are native forest, 153 thousand hectares are used for other purposes and 59 thousand hectares will be planted.

As of December 31, 2011 the logs production volume totaled 18.4 million cubic meters (16.6 million cubic meters as of December 31, 2010).

The main considerations in determining the fair value of biological assets include the following:



| |  | Arauco uses the discounted future cash flows of its forest plantations, which are based on a harvest projection date for all existing plantations.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Current forest equity is projected assuming that total volume does not decrease and a minimum demand equal to the current supply demand.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  | Future plantations are not considered.
|- |  | --------------------------------------



| |  | The harvest of forest plantations supplies raw material for all other products that Arauco produces and sells. By directly controlling the development
of forests that will be processed, Arauco is assured of having high quality timber for each of its products.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | 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 value of the plantations, in accordance with the criteria
previously described, are accounted for in the current financial years income statement, pursuant to IAS 41. These changes are presented in the
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Consolidated Statements of Income under Other income by activity, as of December 31, 2011 amounted to ThU.S.$229,889 (ThU.S.$221,501 as of December 31, 2010). Additionally, cost of sales include a higher
cost of ThU.S.$253,019 as of December 31, 2011 (ThU.S.$200,320 as of December 31, 2010) resulting from the difference between the cost of wood at fair value versus actual cost incurred.



| |  | Forests are harvested according to the needs of Araucos production plants.
|- |  | ---------------------------------------------------------------------------



| |  | The discount rates used are: in Chile 8%, in Argentina 12% and in Brazil 10%.
|- |  | -----------------------------------------------------------------------------



| |  | It is assumed 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:

The following chart show changes in the balance of biological assets considering varariations in
significant assumptions considered at calculating the fair value of the assets:



|              |  |  |      |  |         |  |          |  
|------------- |  |  | ---- |  | ------- |  | -------- | -

|Margins       |  |  | 10   |  |         |  | 397,848  |  
|              |  |  | -10  |  |         |  | (397,848 | )

Differences in the valuation of biological assets in the discount rate and the margins are recorded in the Income
Statement under item Other Operating Income and Other Operating Expenses depending on whether this is profit or loss.

Forestry plantations
classified as current assets correspond to those to be harvested within 12 months.

The Company holds fire insurance policies for its forestry
plantations, which together 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 in partnership
with Stora Enso, which are presented in these consolidated financial statements under the equity method (see Note 16).

As of December 31,
2011, Araucos investment in Uruguay represented a total of 133 thousand hectares, of which 74 thousand hectares are allocated to plantations, 7 thousand hectares to native forest, 46 thousand hectares for other uses, and 6 thousand hectares
for planting.

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.

Fix Term Deposits and Repurchased Agreements:The objective of this instrument is to maximize short-term returns
of cash. This instrument is authorized by Araucos Placement Policy, which establishes a mandate that allows investments in fixed income securities. In general, these instruments have a maturity period of less than ninety days.

Trades and Notes Receivable:These represent enforceable rights for Arauco resulting from the normal course of the business, namely, operation
activity or corporate purposes.

Other Debtors: These correspond to receivables from sales, services or loans that are not considered
within the normal course of the business.

Trades receivables are presented at net value, which means that they are presented net of bad debt
estimates. This provision is determined when there is evidence that Arauco will not receive the payments agreed to in the original sales terms. These provisions are carried out when a customer files for and commences legal bankruptcy proceedings or
is in default of payments, or when Arauco has exhausted all debt collection options within a reasonable period. These include telephone calls, e-mails and debt collection letters.

Fair Value Financial Liabilities with Changes in Income and Loss

As of the closing date of the balance sheet, Arauco held a swap exchange rate as a financial liability at fair value with changes in income and loss. This
liability incurred a net decrease of 53%, due to a rate decrease experienced by the economy in the last period. The decline of 100% in forward exchange rate compared to December 2010, is caused by the expiration of these to date of closing of these
staments. Together these two instruments generated a percentage decline of 75% as of December 2011, in financial liabilities at fair value through changes in outcome compared to December 2010.

Fair Value Hierarchy

The assets and liabilities recorded at fair value in the Consolidated Balance Sheet dated December 31, 2011, have been measured based on the methodologies provided in IAS 39. The methodologies
applied for each financial instrument are classified according to their hierarchy as follows:



| |  | Level I: Values or quoted prices in active markets for identical assets and liabilities.
|- |  | ----------------------------------------------------------------------------------------



| |  | Level II: Information (Inputs) from other sources than the quoted values of Level I, but observable in the market for assets and
liabilities either directly (prices) or indirectly (derived from prices).
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Level III: Inputs for assets or liabilities that are not based on observable market data.

Hedging Instruments

Hedging instruments registered as of December 31, 2011 correspond to cash flow hedges. Specifically, at the closing balance date, Arauco recorded rate swaps resulting at fair value for a total of
ThU.S.$185 which is presented in the Consolidated Balance Sheet in Other financial liabilities, non-current and forward of ThU.S.$909, which is presented in the Consolidated Balance Sheet in Other financial liabilities, current. Their effects in the
present period are presented in Equity as Other comprehensive results, net of exchange rate and deferred taxes.

Nature of Risk

Arauco is exposed to variations in cash flows due to exchange rate risk, mainly resulting from having assets in U.S. Dollars and
liabilities in UF (obligations to the public), which causes mismatches that could affect operating results.

Hedging Swaps H Series Bond

Hedging Objective

In March 2009, Arauco placed a bond for 2,000,000 UF on the Chilean
market with an annual 2.25% coupon and semi-annual interest payments (in March and September). This bond is amortized at the end of the period, with a prepayment option from March 1, 2011. The maturity date is March 1, 2014.

In order to avoid exchange rate risk, Arauco made two cross-currency swap contracts listed below:

Hedging Swaps E Series Bond

Hedging Objective

In November 2008 Arauco placed a series E bond for a total UF 1,000,000,
with a coupon of 4.00%, payable semi-annually. To mitigate the risk of exchange rate Arauco performed a cross-currency swap contract, which fully covered the amount of the bond issued:

Contract 1: Arauco receives semi-annual interests (In April and October) based on a notional amount of UF 1,000,000 at a rate of 4.21% annually, and pays semiannual interests (In April and October) based
on a notional amount of U.S.$43.28 million (equivalent to UF 1,000,000 at the closing exchange rate of the contract) at a rate of 3.36%. The market value amounts to ThU.S.$ -245 as of 31 December 2011. This contract expires on October 30,
2014.

Through a test of effectiveness, Arauco can validate that the above-detailed hedging instruments are highly effective within an
acceptable range for the Company to eliminate exchange rate uncertainty for commitments that are subject of such hedging.

Hedging Strategy

Given that Arauco holds a high percentage of assets in U.S. Dollars, the Company needs to reduce its exchange rate risk as it has
obligations in adjustable-rate Pesos. The aim of this swap is to eliminate exchange rate uncertainty, exchanging cash flows from adjustable-rate Pesos obligations generated by the above mentioned bonds, with U.S. Dollar cash flows
(Araucos functional currency) at a fixed exchange rate and determined at the date of the contract execution.

##### Table of Contents

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.

Type of Risk: Credit Risk

Description

Credit risk
refers to financial uncertainty at different time horizons concerning the fulfillment of obligations subscribed to by counterparties, at the time of exercising contract rights to receive cash or other financial assets on behalf of Arauco.

Explanation of Risk Exposure and How These Risks Arise

Araucos exposure to credit risk is directly related to each of its customers individual capacities to fulfill their contractual commitments, reflected in commercial debtor accounts.
Furthermore, credit risk also arises for assets that are in the hands of third parties such as fixed term deposits, agreements and mutual funds.

With regard to trade accounts receivables, as a policy, Arauco holds insurance policies for open account sales. These are intended to cover export sales from the Company, Aserraderos Arauco S.A., Paneles
Arauco S.A. and Forestal Arauco S.A., as well as local sales of Arauco Distribución S.A., Arauco México S.A. de C.V., Arauco Wood Inc., Arauco Colombia S.A., Arauco Perú S.A. and Alto Paraná S.A. (and affiliates). Arauco
works with Continental Credit Insurance Company (AA- Fitch Ratings from January 13, 2011). Arauco do Brasil (Brazil) local sales credits are insured with Euler Hermes Insurance Company. These insurance policies cover 90% of the invoice with no
deductible.

In order to guarantee a credit line or an advanced payment to a supplier approved by the Credit Committee, Arauco holds several
guarantees, such as mortgages, pledges, standby letters of credit, bank guarantee bonds, checks, promissory notes, consumption loans or any other guarantee that may be needed pursuant to each countrys legislation. Debt covered by this type of
guarantee amounted to U.S.$86.91 million in December 2011. The guarantee procedure is regulated by Araucos Guarantee Policy, which controls accounting and reporting, maturity dates and value.

The Companys maximum credit risk exposure is limited to the amortized cost value of the registered trade accounts receivable, at the date of this
report, less the sales percentage insured by aforementioned credit insurance companies and by the guarantees provided to Arauco.

During the
year 2011, Araucos consolidated sales amounted to ThU.S.$4,374,495 that according to the agreed term of sales, 64.26 % correspond to credit sales, 26.81% to sales with letters of credit, and 8.93 % to other classes of sales.

As of December 31, 2011, Araucos Sales Debtors amounted to ThU.S.$639,761 that according to the agreed term of sales, 61.82%
corresponded to credit sales, 32.14% to sales with letters of credit and 6.03% to other classes of sales, distributed among 2,016 clients. The client with the highest open account debt did not exceed 2.27% of total receivables at that date.

The receivables covered by the different insurance and guarantee policies reaches 98.19%, therefore, Araucos exposure portfolio is
1.81%.

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 from Asia and the Middle East. Credit assessments of the issuing banks are
performed periodically, in order to obtain ratings made by the principal risk classification companies of country and world risk rankings, and of their financial position over the last five years. Depending on this evaluation, it is decided whether
the issuing bank is approved or confirmation is requested.

All sales are controlled by a credit verification system that has set parameters
to block orders from clients who have accumulated past due amounts of a defined percentage of the debt and/or clients who at the time of product delivery have exceeded their credit limit or whose credit has expired.

Of the total accounts receivable as of December 31, 2011, 87.67% is current, 7.94% is between 1 and 15 days past due, 1.59% is between 16 and 30
days past due, 0.16% is between 31 and 60 days past due, 0.46% is between 61 and 90 days past due, 0.77 % is between 91 and 180 days past due, being the maximum distribution of credit for Arauco.

Investment Policy:

Arauco has an Investment Policy that which identifies and limits financial instruments and companies in which Arauco and its subsidiaries are authorized to invest in, specifically, Celulosa Arauco y
Constitución S.A.

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.

With regard to financial instruments, the only permitted investments are fixed income investments and instruments with adequate liquidity.
Each instrument has defined classifications and limits, which depend on duration and on the issuer.

With regard to intermediaries (such as
banks, brokers dealers and mutual funds), a methodology is used with the objective of determining the relative risk level of each bank or entitys financial position and debt and asset security using a point system that gives each subject
entity a relative risk ranking. Arauco uses this system to define investment limits.

The required records for evaluation of the various
criteria are obtained from official Financial statements provided by the banks under evaluation and from the classification of in-effect short and long term debt securities, as defined by the controlling entity (the Superintendency of Banks and
Financial Institutions) and used by risk classification companies authorized by the controlling entity, which in this case include Fitch Ratings Chile, Humphreys and Feller Rate.

Evaluated criteria are: Capital and Reserves, Current Ratio, Equity Share in Total Investments in Financial System, Capital Yield, Operational Income Net Profit Ratio, Debt / Capital Ratio and the Risk
Classifications 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.

Type of Risk: Liquidity Risk

Description

This risk corresponds to
Araucos ability to fulfill debt obligations at the time of expiration.

Explanation of Risk Exposure and How These Arise

Araucos exposure to liquidity risk is found mainly in its obligations to the public, banks and financial institutions, creditors and
other payables. These may arise if Arauco is unable to meet 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 constantly monitors the Companys cash flow forecasts based on short and long term forecasts and available financing alternatives. In order to control the risk
level of available financial assets, Arauco follows its investment policy.

Guarantees given

As of the date of these financial statements, Arauco holds about U.S.$15 million as financial assets passed to third parties (beneficiaries), as a direct guarantee. If Arauco does not meet its obligation,
the beneficiaries can seek relief under the warranty.

As of December 31, 2011, the assets covered by an indirect guarantee amounted to
U.S.$999 million. The indirect guarantees are given to protect the obligation assumed by a third party, either a related company or an unrelated company (the buy-back operations that guarantee the obligation of forest service enterprises amounted to
U.S.$52 million, which in the event of default, Arauco can cancel the obligation to obtain the asset exchange contract).

On
September 29, 2011, Arauco signed a Security Agreement under which awarded a joint and not several guarantee limited to 50% of the obligations Uruguayan companies (joint ventures) called Celulosa y Energía Punta Pereira S.A. and Zona
Franca Punta Pereira S.A., under the IDB Facility Agreement by the amount of U.S.$454,000,000 and the Finnevera Guaranteed Facility Agreement in the amount of U.S.$900,000,000. Both loan agreements were signed with the International Development
Bank. Such guarantee is reflected in the table below, under indirect guarantees.

Type of Risk: Market Risk  Exchange Rate

Description

This risk arises from the probability of being affected by losses from
fluctuations in exchange rate in currencies in which assets and liabilities are denominated, in a functional currency different than the one defined by Arauco.

Explanation of Risk Exposures and How these Arise

Arauco is exposed to the risk of U.S. Dollar (functional currency) fluctuations for sales, purchases and obligations in other currencies, such as the
Chilean Peso, Euro, Brazilian Real or others. In the case of significant exchange rate variations, the Chilean Peso is the currency that represents the main risk.

Explanation of Risk Management Objectives, Policies and Processes, and Measurement Methods

Arauco performs sensitivity analyses to measure the effect of this variable on EBITDA and Income.

Sensitivity analysis considers a variation of + / - 10% of the exchange rate as of December 31, 2011 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 + / - 0.01% (equivalent to ThU.S.$102.31), on the income after tax and + / - 1.06% (equivalent to ThU.S.$3,711.27) and 0.04% on equity (equivalent to ThU.S.$3,043.08).

The main financial instruments subject to exchange rate risk are local bonds issued in UF. These are not covered by swaps described in the Hedging chapter.

|--- | -------------------------------------------------------------------------------------------------------------------------------

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 balance sheet 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 + / - 0.11% (equivalent to ThU.S.$ 670) and a change on the heritage of + / - 0.01% (equivalent to ThU.S.$ 670).

Type
of Risk: Market Risk  Interest rate

Description

This risk refers to the sensitivity of the value of financial assets and liabilities in terms of interest rate fluctuations.

Explanation of Risk Exposure and How These Arise

Arauco is exposed to risks due to
interest rate fluctuations for obligations to the public, banks and financial institutions and financial instruments that accrue 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, 2011, 13% 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 + / - 0.32% (equivalent to
ThU.S.$1,103.77) and + / - 0.01% (equivalent to ThU.S.$954.86) on equity.

Type of Risk: Market Risk  Price of Pulp

Description

Pulp price is 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 Risk Exposure and How These Arise

Pulp prices are reflected in operational
sales and directly affect the net income for the period.

As of December 31, 2011, operational income due to pulp sales accounted for
47.2% 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 + / - 17.10% (equivalent to
U.S.$103.92 million), on the income after tax and + / - 11.19% (equivalent to U.S.$54.50 million) and + / - 1.97% (equivalent to U.S.$143.98 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 payment is determined based on the effective realized income, 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 required and additional dividend, the following unrealized results are excluded from the results of the exercise:



|1) | Those relating to the fair value recorded for forestry assets covered by IAS 41, restoring them to the net income at the time of its completion. For these purposes,
this includes the realized portion of such increases in fair value for assets sold or disposed by other means.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2) | Those generated through the acquisition of entities. These results will be restored to the net income at the time of their realization. For this purpose, the results
are realized when acquired entities generate an income after their acquisition or when such entities are sold.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The deferred taxes associated with the amounts described in points 1) and 2) are also excluded.

The following table details adjustments made for the determination of distributable net income as of December 31, 2011 and 2010 corresponding to 40%
of the distributable net income for each period:

3) On
December 31, 2011, a number of forest fires have erupted in the region of Bío Bío. As a result of the high temperatures and strong winds, the forest fires have spread considerably, affecting Araucos forestry affiliates
plantations and, as of early this morning, the Nueva Aldea Industrial Forestry Complex located in the Commune of Ranquil (the Nueva Aldea Complex).

As of today, the blaze has affected about four thousand hectares of Araucos forest plantations.

On the other hand, and as mentioned above, the forest fires reached the Nueva Aldea Complex, materially affecting the panel mill, which has an annual production capacity of 450,000 cubic meters.

The fire has not affected other Nueva Aldea Complex facilities, which include, in addition to the panel mill, a pulp mill, a logging mill, a
saw mill and biomass-based power plants. All possible preventive measures have been taken to prevent the fire from reaching these industrial units, which is why the fire has only affected the panel mill.

As a preventive measure, Arauco has shutdown all industrial facilities of the Nueva Aldea Complex, safeguarding the safety and protection of its workers
from the very beginning. Until now, no casualties have been reported.
