1. ANALYSIS OF FINANCIAL POSITION

a) Interim Statement of Financial Position

The principal components of assets and liabilities at the end of each period are as follows:

Assets	09-30-2021 ThU.S.$		12-31-2020 ThU.S.$		Variation ThU.S.$
Current assets		4,285,748		3,544,325		741,423
Non-current assets		12,691,369		12,483,994		207,375
Total assets		16,977,117		16,028,319		5.92	%

Liabilities	09-30-2021 ThU.S.$		12-31-2020 ThU.S.$		Variation ThU.S.$
Current liabilities		1,860,712		1,097,593		763,119
Non-current liabilities		7,312,525		7,515,091		(202,566	)
Non–parent participation		25,748		30,913		(5,165	)
Net equity attributable to parent company		7,778,132		7,384,722		393,410
Total net equity and liabilities		16,977,117		16,028,319		5.92	%

As of September 30, 2021, total assets increased MU.S.$ 949 compared to December 31, 2020, equivalent to a 5.92% variation. This variation was driven mainly by an increase in property, plants & equipment resulting from the investment in the MAPA project, accounts receivable from sales to national and foreign customers, cash in banks and term deposit, which was partially offset by decreases in current tax assets and biological assets.

In turn, total liabilities increased by MU.S.$ 561 principally due to a determination and registration of dividend provisions (see Note 26)

The main financial and operational indicators related to the Statement of Financial position as of the dates and for the periods indicated below are as follows:

Liquidity ratios	09-30-2021		12-31-2020
Current Liquidity (current assets / current liabilities)		2.30		3.23
Acid ratio ((current assets-inventories, biological assets) / current liabilities)		1.55		2.10

Debt indicators	09-30-2021		12-31-2020
Debt to equity ratio (total liabilities / equity)		1.18		1.16
Short-term debt to total debt (current liabilities / total liabilities)		0.20		0.13
Long-term debt to total debt (non-current liabilities / total liabilities)		0.80		0.87
	09-30-2021		09-30-2020
Financial expenses coverage ratio (earnings before taxes + interest expense / interest expense)		7.75		0.72

Activity ratio	09-30-2021		12-31-2020
Inventory turnover-time (cost of sales / inventories + current biological assets)		2.74		2.68
Inventory turnover-time (excluding biological assets) (Cost of sales /inventory)		3.58		3.46
Inventory permanence-days ((inventories + biological assets) /cost of sales)		131.45		134.30
Inventory permanence-days (excluding biological assets) (inventory / cost of sales)		100.66		104.08

As of September 30, 2021, the short-term debt to total debt ratio represented 20% of total liabilities (13% as of December 31, 2020).

Our financial expenses coverage ratio increased from 0.72 to 7.75, mainly due to the profits before taxes generated for the period ended September 30, 2021, compared to a loss before taxes generated in the same period of 2020.

b) Interim Statement of Profit or Loss

Profit before income tax

We recorded a profit before income tax of approximately MU.S.$ 1,150 compared to a loss of approximately MU.S.$ 57 in the same period of 2020. The variation of MU.S.$ 1,207 is explained by the factors described in the following table:

Item	MU.S.$
Gross margin		1,030
Distribution and Administrative Expenses		(145	)
Other income and expenses		248
Others		74
Net change in profit (loss) before income tax		1,207

The main indicators related to the accounts in our statements of profit or loss and the details of revenues and operation costs are as follows:

Revenues	09-30-2021 ThU.S.$		09-30-2020 ThU.S.$
Pulp		2,047,958		1,513,880
Wood		2,559,203		1,865,991
Other		190		82
Total revenues		4,607,351		3,379,953

On January 1, 2021 we discontinued the reporting of our forestry operations as a business segment, and included those operations as part of the pulp segment. This is in line with Arauco´s current reality and with the way in which the management views the progress of business.

The new segments reported are Pulp and wood products, consistent with Arauco´s focus on end customers. For more information, see Notes 2 and 24 to the Interim Consolidated Financial Statements Report as of September 30, 2021.

2. MAIN SOURCES OF FINANCING

Arauco’s financing needs are mainly covered through the capital markets, with bond issuances and credits obtained from banks and financial institutions serving as the main sources of financing.

For short-term borrowing, Arauco follows a liquidity policy which indicates the amounts and institutions from which it can borrow according to several conditions defined in the policy.

In the case of long-term debt, corporate bond issuances in the local market and also in the international markets are used as sources of new resources.

Another source of long-term financing corresponds to borrowings from banks and financial institutions around the world.

3. MARKET SITUATION

During the third quarter, pulp demand remained stable, with some minor price declines in some markets towards the end of the quarter, due to the low season in the northern hemisphere. Customers in every market, but mainly in Asia, have been affected by the rise in logistics costs, which made them reduce their exports and concentrate in the domestic market. World inventories for both fibers increased between June and August 2021, short fiber increased by 8 days and long fiber by 6 days.

In China, pulp demand started to decline towards the end of the third quarter because mills in all type of industries had to reduce their operating rate or stop their production lines due to the government limiting energy consumption in several provinces in the country. The tissue industry started to improve, with some producers achieving some price increases to their final products. The P&W industry remained relatively stable during the quarter, with some producers trying to implement price increases. Long fiber prices remained steady through the quarter, however, short fiber prices decreased. The spread between the long and short fiber, after decreasing for several quarters, began to increase considerably, reaching US$205 at the end of September 2021.

In Europe, pulp demand continued positively throughout the quarter, price remained unchanged at a high level, which caused the price spread with China to increase towards the end of the quarter. The tissue industry started the quarter weak, however, during the quarter it began to improve in both the At-Home and Away-from-Home segments. The P&W industry remained strong, with very good demand for their products, and producers were able to implement price increases for their final products. By the end of the quarter, some producers in the paper industry started to be affected by high energy prices, and to a lesser extent, high chemical prices.

The dissolving pulp market remained steady, with prices slightly declining due to lower demand. The viscose market, after remaining stable during the first months of the quarter, began to deteriorate due to increases in some of their costs.

Production during the third quarter was higher than Q2, but slightly lower compared to the same period of 2020. During the quarter we had the programmed maintenance stoppage of the Licancel mill, in Chile.

Wood Products Business

Panels

Revenues increased when compared to the second quarter, mainly as a result of a 10.8% increase in average prices. Sales volume increased 2.3%.

During the third quarter, demand continued at high levels. The foregoing is explained by an strong demand for products of home improvement and remodeling. We observed this for most of our products, such as MDF, PB and mouldings.

Sawn timber

During the third quarter sales volume decreased by 2.0% while average prices increased by 14.9%.

During the beginning of the third quarter, we observed strong demand and prices especially for remanufactured wood products. Sawn Timber demand decreased somewhat by mid-quarter, especially in China.

Plywood

Sales volume increased by 6.5% during the third quarter, coupled with an increase in average prices of 9.5%. Higher demand in markets such as Chile, Europe, Oceania and the US, despite some effects arising from logistical issues leading to some shipping delays.

4. ANALYSIS OF INTERIM CASH FLOW

The main components of cash flow in each period are as follows:

	09-30-2021 ThU.S.$			09-30-2020 ThU.S.$
Positive (negative) Cash flow
Net cash flows from operating activities		1,397,646			804,684
Cash flows from (used in) financing activities:
Issuance of shares		200,000			250,000
Obtaining and paying loans and bonds		(249,196	)		(90,122	)
Payment of lease liabilities		(52,600	)		(55,731	)
Dividends paid		(167	)		(394	)
Others		(1,487	)		(8,938	)
Cash flows from (used in) investment activities:
Purchase and sale of property, plant and equipment		(922,003	)		(1,097,274	)
Purchase and sale of biological assets		(132,010	)		(150,200	)
Purchase and sale of intangible assets		(3,382	)		(10,165	)
Additions (disposals), investments in subsidiaries, joint ventures and associates		43,155			(15,252	)
Dividends received		1,454			4,042
Others		(1,633	)		2,236
Positive (negative) net cash flow		279,777			(367,114	)

Our cash flow from operating activities increased to MU.S.$ 1,398 for the current period (compared to the positive balance of MU.S.$ 805 for the same period in 2020), resulting mainly from higher revenue from customer collections and tax refunds available in the current period.

The cash flow from financing activities shows a negative balance of MU.S.$ 103 for the current period (compared to the positive balance of MU.S.$ 95 for the same period in 2020). The decrease is attributable to the increase in financial debts in the previous period compared to the current period.

Regarding the cash flow from investment activities, the balance decreased to MU.S.$ 1,014 (compared to MU.S.$ 1,267 for the same period of 2020), mainly due to lower disbursements made for the purchase of property, plant and equipment and the sale of the participation in the subsidiary Forestal Los Lagos SpA of MU.S.$ 48 in the current period.

5. MARKET RISK ANALYSIS

In respect of the economic risks resulting from interest rate variations, the Company maintains, as of September 30, 2021 a ratio of fixed rate debt to total consolidated debt of approximately 94.2%, which we believe is consistent with industry standards.

Regarding variations in prices of pulp and forestry products, since the risks of price fluctuation are limited/can be managed without hedging, the Company does not participate in futures trading, which allows it to maintain one of the lowest cost structures in the industry, thes risks are bounded.

The Company and most of its subsidiaries maintain their accounting records and prepare their financial statements in U.S. dollars. Most of their revenues (and accordingly accounts receivable) are denominated in U.S. dollars, and most financial liabilities are either denominated in U.S. dollars or are covered by exchange rate swaps. As a result, exposure to exchange rate fluctuations has decreased significantly.

The Interim Consolidated Financial Statements as of September 30, 2021, include a detailed analysis of the risks associated with the business of Arauco (see Note 23).

NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS AS OF SEPTEMBER 30, 2021 AND 2020 AND AS OF DECEMBER 31, 2020

NOTE 1. PRESENTATION OF INTERIM CONSOLIDATED FINANCIAL STATEMENTS

Entity Information

Celulosa Arauco y Constitución S.A. and subsidiaries, (hereafter “Arauco” or the “Company”), tax identification number 93,458,000-1, is a closely held corporation, that was registered in the Securities Registry (the “Registry”) of the Chilean Commission for the Financial Market (“CMF”) as No. 042 on June 14, 1982. Additionally, the Company is registered as a non-accelerated filer in the Securities and Exchange Commission (SEC) of the United States of America.

The Company’s head office address is El Golf Avenue 150, 14^th floor, Las Condes, Santiago, Chile.

Arauco is principally engaged in the production and sale of products related to the forestry and timber industries. Its main operations are focused on business areas of pulp and wood products.

As of September 30, 2021, Arauco is controlled by Empresas Copec S.A., tax identification number 90,690,000-9, which owns 99,978048% of Arauco, and is registered in the Securities Registry as No. 0028. Each of the above mentioned companies is subject to the oversight of the CMF.

Moreover, Empresas Copec S.A. is controlled by the public corporation AntarChile S.A., tax identification number 96,556,310-5, which owns 60,8208% of Empresas Copec S.A. Furthermore, the ultimate shareholders of AntarChile S.A. and, consequently, of Empresas Copec S.A., are Mr. Roberto Angelini Rossi, tax identification number 5,625,652-0, and Mrs. Patricia Angelini Rossi, tax identification number 5,765,170-9.

Functional and Presentation Currency

Arauco and most of its subsidiaries determined the United States (“U.S.”) Dollar as its functional currency since the majority of its revenues from sales of its products are derived from exports denominated in U.S. Dollars, while their costs of sales are to a large extent related or indexed to the U.S. Dollar.

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

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

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

The currency used to finance operations is mainly the U.S. Dollar.

The presentation currency of the consolidated financial statements is the U.S. Dollar. Figures on these interim consolidated financial statements are presented in thousands of U.S. Dollar (ThU.S.$).

Summary of significant accounting policies

a) Basis for preparation of the interim consolidated financial statements

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

The interim consolidated financial statements have been prepared on a historical cost basis, except for biological assets and certain derivative financial instruments which are measured at revalued amounts or fair value at the end of each period as explained in the following significant accounting policies.

b) Critical accounting estimates and judgments

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

- Biological Assets

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 a discounted basis, based on our sustainable forest management plans and the estimated growth of forests.

The measurement of the fair value of the biological assets is determined using a discounted cash flow model. Our cash flow projections include significant judgments and assumptions relating to discount rates, estimated growth of the forests and sales margins. This valuation is performed on the basis of each identifiable farm block and for each type of tree. The main considerations used to calculate the valuation of forest plantations and a sensitivity analysis are presented in Note 20.

- Litigation and Contingencies

Arauco and its subsidiaries are subject to certain litigation proceedings. Future impact on Arauco’s financial condition derived from such litigations is estimated by management, in collaboration with its legal advisors. Arauco applies judgment when interpreting the reports of its legal advisors who provide updated estimates of the legal contingencies at each reporting period and/or at each time a modification is determined to be necessary. For a description of current litigations see Note 18.

c) Consolidation

The interim consolidated financial statements include all entities over which Arauco has the power to direct the relevant financial and operating activities. Subsidiaries are consolidated from the date on which control is obtained and up to the date that control ceases.

Specifically, a company controls an investee or subsidiary if, and only if, they have all of the following:

(a) power over the investee, i.e. the investor has existing rights which give it the ability to direct the relevant activities (the activities that significantly affect the investee’s returns);

(b) exposure or rights to variable returns from involvement with the investee; and

(c) the ability to use power over the investee to affect the amount of the investor’s returns.

When Arauco holds less than the majority of the voting rights in a company in which it participates, it nonetheless has the power over said company - when these voting rights are enough - to grant it in practice the ability to unilaterally direct said company’s relevant activities. Arauco takes into account all facts and circumstances in order to assess if the voting rights in a company in which it participates are enough for granting it the power, including:

a) the size of the investor’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders;

b) potential voting rights held by the investor, other vote holders or other parties;

c) rights arising from other contractual arrangements; and

d) any additional facts and circumstances that indicate the investor has, or does not have, the current ability to direct the relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings.

The Company will reevaluate whether or not it holds control of a company in which participates if the facts and circumstances indicate that changes have occurred in one or more of the three elements of control mentioned above.

Consolidation of an investee shall begin from the date the investor obtains control of the investee and cease when the investor loses control of the investee. An entity includes the income and expenses of an acquired or sold subsidiary in the interim consolidated financial statements from the date it gains control until the date when the entity ceases to control the subsidiary.

The profit or loss of each component of other comprehensive income is attributed to owners of the parent company and the non-controlling interest, as appropriate. Total comprehensive income is attributed to the owners of the parent company and non-controlling interests even if the results of the non-controlling interest have a deficit balance.

If a subsidiary uses accounting policies other than those adopted in the interim consolidated financial statements for transactions and other events in similar circumstances, appropriate adjustments are made to the interim consolidated financial statements of subsidiaries in order to ensure compliance with Arauco’s accounting policies.

All intercompany transactions and unrealized gains and losses from subsidiaries have been fully eliminated from these interim consolidated financial statements and non-controlling interest is presented in the interim consolidated statement of financial position within equity.

The interim consolidated financial statements at the end of this period include the assets, liabilities, income and expenses of the subsidiaries shown in Note 13.

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

A parent company will present non-controlling interests in the interim consolidated statement of financial position within equity, separately from the equity of the owners of the parent company.

d) Segments

Arauco has defined its reportable segments according to its business areas, based on the products and services sold to its customers. This definition is consistent with the management, resource allocation and performance assessment made by key personnel responsible for making relevant decisions related to the Company’s operation. The personnel responsible for making such decisions are the Executive Vice-president and the Chief Executive Officer who are the highest authorities for making decisions and are supported by the Vice-presidents of each segment.

Based on the aforementioned process, the Company has established reportable segments according to the following business units:

• Pulp

• Wood products

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

e) Functional currency

(i) Functional currency

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

(ii) Translation to the presentation currency of Arauco

For the purposes of presenting interim consolidated financial statements, assets and liabilities of Arauco’s operations in a functional currency different from Arauco’s are translated into U.S. dollars using exchange rates prevailing at the end of each reporting period. Income and expense items are translated at the average exchange rates for the period, unless exchange rates fluctuate significantly during that period, in which case the exchange rates at the dates of the transactions are used. Exchange rate differences are recognized in other comprehensive income and accumulated in “Other reserves” within–equity.

(iii) Foreign Currency Transactions

Transactions in currencies other than the functional currency are recognized at the exchange rates prevailing at the dates of the transactions. Profit or loss on transactions in currencies other than the functional currency resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies, are recognized in the interim consolidated statements of profit or loss, except those which are recorded in other comprehensive income and accumulated in equity such as cash flows hedging derivatives.

f) Cash and cash equivalents

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

g) Financial Instruments

Financial assets

Initial classification

Arauco classifies its financial assets into the following categories: fair value through profit or loss and amortized cost.

Arauco does not have financial assets at fair value through other comprehensive income.

The classification is based on the business model used to manage the assets and the characteristics of their contractual cash flows.

Management determines the classification of its financial assets at the time of their initial recognition.

(a) Financial assets at fair value through profit or loss: these instruments are initially measured at fair value. Net income and losses, including any income from interest or dividends, are registered in the profit or loss of the period. Financial assets are classified in the category of financial assets at fair value through profit or loss when they are maintained for negotiation or designated in their initial registration as assets at fair value through profit or loss. A financial asset can be classified in this category if it is acquired mainly for the purposes of being sold in the short-term. Gain or losses of assets held for negotiations are registered in the consolidated statements of Profit or Loss, and the related interest is registered independently as financial income. Derivatives are classified as acquired for negotiation also unless they are designated as hedging instruments.

(b) Assets measured at amortized cost: they are initially registered at the fair value of the transaction, adding or subtracting the transaction costs that are directly attributable to the issuance of the financial asset or financial liability. The financial asset is maintained within a business model, the objective of which is to maintain financial assets to obtain contractual cash flows and the contractual conditions of the asset give rise, on specified dates, to cash flows that are solely payments of principal and interests (“SPPI”) over the amount of the outstanding principal.

Subsequent measurement

Financial instruments are subsequently measured at fair value through profit or loss or amortized cost.

The classification is based on two criteria: i) the Company’s business model for the management of financial instruments, and ii) whether the contractual cash flows related to the financial instruments represent “Solely Payments of Principal and Interests”.

a) Financial assets at fair value through profit or loss: these instruments are subsequently measured at fair value. Net earnings and losses, including income from interests and dividends, are registered as profits or losses for the period. These instruments are held for negotiation and they are mainly acquired to be sold in the short term. Derivatives are also classified as held for negotiation, unless they are registered as hedging instruments. Financial instruments of this type are classified as Other Current and Non-Current Financial Assets. They are subsequently valuated by determining their fair value, registering changes in value in the interim interim consolidated statements of Profit or Loss, in the items of Financial Income or Financial Costs.

b) Financial assets measured at amortized cost: These instruments are subsequently measured at amortized cost minus accumulated amortizations, using the effective interest method and adjusted by loss allowance and volume discounts, in the case of financial assets. Financial income and expenses, foreign exchange income and losses, and impairment are registered in results. Any earnings or losses due to initial or subsequent reductions of the value of the asset are registered in the statement of profit or loss of the period. Loans and receivables are non-derivative financial instruments with fixed or determinable payments not traded in any active market. They are registered at amortized cost, registering accrued conditions directly in profit or loss.

Arauco measures accumulated losses in a quantity equivalent to expected credit losses during the lifelong commitment. Expected credit losses are based on contractual cash flow differences based on the allowance of each contract and the cash flows that Arauco expects. The difference is then discounted based on an approximation of the asset’s original effective interest rate. The asset’s carrying value is reduced as the allowance is used, and the loss is recognized in sales expenses in the interim consolidated statements of profit or loss. When an account receivable cannot be collected, it is regularized against the allowance account for receivables. Subsequent recoveries of previously impaired amounts are recognized as a debit in selling expenses.

Derivative financial instruments are explained in Note 1 h).

Financial liabilities

Arauco classifies its financial liabilities as follows: fair value through profit or loss, derivatives designated as effective hedging instruments and amortized costs.

Management determines the classification of its financial liabilities upon initial recognition. Financial liabilities are derecognized when the obligation is cancelled, settled or expired. When an existing financial liability is replaced with another of the same provider under substantially different terms, or where the terms of an existing liability are substantially amended, such exchange or modification is treated as a write-off of the original liability, with a new liability being recognized, and the difference between the respective carrying amounts is recognized in the interim consolidated statement of profit or loss.

Financial liabilities are initially recognized at fair value, and in the case of loans, they include the costs directly attributable to the transaction. The subsequent measurement of the financial liabilities depends on their classification:

Financial Liabilities at fair value through profit or loss

Financial liabilities are included in the category of financial liabilities at fair value through profit or loss when they are held for trading or originally designated at fair value through profit or loss. Income and losses from liabilities held for trading are recognized in profit or loss. This category includes non-designated derivatives for hedging accounting.

Financial Liabilities at amortized cost

Other financial liabilities are subsequently valued at their amortized cost based on the effective interest rate method. The amortized cost is calculated taking into account any premium or acquisition discount and includes the costs of transactions that are an integral part of the effective interest rate. This category includes Commercial Accounts Payable and Other Accounts Payable, lease liabilities, as well as the loans included in Other Current and Non-Current Financial Liabilities.

h) Derivative financial instruments

(i) Derivative Financial Instruments - The Company enters into a variety of derivative financial instruments to manage its exposure to interest rate and foreign exchange rate risks, including foreign exchange forward contracts, interest rate swaps, currency swaps and zero cost collar contracts. The Company’s policy is to enter into derivatives contracts only for economic hedging purposes and there are no instruments with speculation objectives.

Derivatives are initially recognized at fair value at the date the derivative contracts are entered into and are subsequently re-measured at fair value at the end of each reporting period. The resulting gain or loss is recognized in profit or loss unless the derivative is designated as a hedging instrument and complies with hedge accounting requirements, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

(ii) Embedded derivatives

The Company assesses the existence of embedded derivatives in financial instrument contracts. Derivatives embedded in non-derivative host contracts are treated as separate derivatives when they meet the definition of a derivative, their risks and characteristics are not closely related to those of the host contracts and the contracts are not measured at FVTPL as a whole. Arauco has determined that no embedded derivatives currently exist.

(iii) Hedge accounting

The Company designates certain hedging instruments as either fair value hedges or cash flow hedges.

At the inception of the hedge relationship, the entity documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, Arauco documents whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item attributable to the hedged risk.

-Fair Value Hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

-Cash flow hedges

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income and accumulated under the heading of cash flow hedging reserve. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss, and is included in the Finance costs line item in the interim consolidated statement of profit or loss. Amounts previously recognized in other comprehensive income are reclassified to profit or loss in the periods when the hedged item affects profit or loss, in the same line as the recognized hedged item.

Hedge accounting is discontinued when the Group revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or when it no longer qualifies for hedge accounting. Any gain or loss recognized in other comprehensive income and accumulated in equity at that time remains in equity and is recognized when the forecasted transaction is ultimately recognized in profit or loss. When a forecasted transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

i) Inventories

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

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

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

Biological assets are transferred to inventories when forests are harvested.

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

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

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

j) Non-current assets held for sale

Arauco classifies certain property, plant and equipment, intangible assets, investments in associates and disposal groups (groups of assets to be sold together with their directly associated liabilities) as non-current assets held for sale which as of the date of the interim consolidated statements of financial position are the subject of active sale efforts which are estimated to be highly probable.

These assets or disposal groups are measured at the lower of the carrying amount or the fair value less the costs to sell, and are no longer depreciated or amortized from the time they are classified as non-current assets held for sale.

k) Business Combinations

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

-Deferred tax assets or liabilities, and assets or liabilities related to employee benefit arrangements are recognized and measured in accordance with IAS 12 Income Taxes and IAS 19 respectively;

-liabilities or equity instruments related to share-based payment arrangements of the acquiree or share-based payment arrangements of the Group entered into to replace share-based payment arrangements of the acquiree are measured in accordance with IFRS 3 at the acquisition date; and

-assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations are measured in accordance with such standard.

Acquisition-related costs are accounted for as expenses when they are incurred, except for costs to issue debt or equity securities which are recognized in accordance with IAS 32 and IFRS 9.

A parent will present non-controlling interests in the interim consolidated statement of financial position within equity, separately from the equity of the owners of the parent company.

Changes in the ownership interest of a parent in its subsidiary that do not result in a loss of control are treated as equity transactions. Any difference between the amount by which non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to owners of the parent company. No adjustment is made to the carrying amount of goodwill, neither gains nor losses are recognized in the statement of profit or loss.

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

Arauco measures the fair value of the acquired company in the business combination achieved in each stage (“step acquisition”), recognizing the effects of remeasurement of previously held equity in the acquiree in the interim consolidated statements of profit or loss.

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

Business combinations that are under common control transactions are accounted using as a reference the pooling of interest. Under this method, assets and liabilities related to the transaction carry over the previous carrying values. Any difference between assets and liabilities included in the consolidation and the consideration transferred, is accounted in equity.

l) Investments in associates and joint arrangements

Associates are entities over which Arauco exercises significant influence, but not control. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

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

Investments in joint arrangements are classified as a joint venture or as a joint operation. A joint operation is a joint arrangement in which the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement in which the parties that have joint control of the arrangement (i.e., participants in a joint venture) have rights to the net assets of the arrangement.

Investments in associates and joint ventures are accounted for using the equity method and are initially recognized at cost. Their carrying amount is increased or decreased to recognize the portion corresponding to the statement of profit or loss or to the statement of comprehensive income. Dividends received are recognized by deducting the amount received from the carrying amount of the investment. Arauco’s investment in associates includes goodwill (both net of any accumulated impairment loss).

The investments in joint operations are recognized through consolidation of assets, liabilities and results of operations in relation to Arauco’s ownership percentage.

If the acquisition cost is lower than the fair value of the net assets of the associate acquired, the difference is recognized directly in statement of profit or loss in line Other gains (losses).

Investments in associates and joint ventures are presented in the interim consolidated statement of financial position in the line item “Investments accounted for using equity method”.

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

m) Intangible assets other than goodwill

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

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

(i) Computer Software

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

(ii) Water Rights, Easements and Other Rights

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

(iii) Customers and trade relations with customers

Correspond to the valuation over the time of the established relationship with customers, from the sale of products and services through its sales team. These relations will materialize in sales orders, which generate revenue and cost of sales. The useful life has been determined to be 15 years.

n) Goodwill

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

Goodwill is not amortized but tested for impairment on annual basis.

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 or a group of cash generating units expected to benefit from the synergies of the combination irrespective of whether other assets or liabilities of the acquired company are allocated to those units or group of units.

The goodwill generated on acquisitions of foreign companies, is expressed in the functional currency of such foreign company.

Goodwill recognized in subsidiaries Arauco Canada Ltd. and Arauco do Brasil S.A., generated on subsidiaries acquisitions whose functional currency is different from the functional currency of the parent company and presentation of these financial statements, are translated into U.S. Dollars at the closing exchange rate.

o) Property, Plant and Equipment

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

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

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

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

The useful lives of the items of property, plant and equipment is estimated according to the expected use of the assets. The residual values and useful lives of assets are reviewed and adjusted, if appropriate, annually.

p) Leases

Arauco applies IFRS 16 for recognizing leases in a manner consistent with contracts with similar features and akin circumstances.

At the beginning of a contract, Arauco assesses whether the contract is, or if it contains, a lease. A contract is, or contains, a lease if it transfers the right to control the use of a given asset for a certain period of time, in exchange for consideration.

As of the initial date for recording a lease, Arauco, as lessee, recognizes an asset by the right of use at cost.

The cost of the asset for right of use comprises:

- The amount of the initial measurement of the lease liability. This measurement is at present value of the payments for leases that have not been disbursed as of that date. Payments for leases are discounted using the incremental interest rate for financial loans;

- Payments for leases performed prior to or as of the initiation date, minus the lease incentives that have been received;

- The initial direct costs incurred by the lessee; and

- An estimation of the costs to be incurred by the lessee when dismantling and eliminating the underlying asset, restoring the location where the same is located, or restoring the underlying asset to the condition required under the terms and conditions of the lease, unless such costs are incurred in order to produce inventories. The lessee assumes obligations stemming from such costs either at the commencement date, or as a result of having used the underlying asset during a specific period.

25

Unaudited Interim Consolidated Financial Statements

September 30, 2021

Amounts in thousands of U.S. dollars, except as indicated

After the initial recognition date, Arauco, as lessee, recognizes its asset for right of use by applying the cost model, minus the accumulated depreciation and impairment losses, and adjusted for remeasurement of the liability for lease.

At the beginning, Arauco in the capacity of lessee, recognizes the lease liability at present value of the lease payments that have not been disbursed as of that date. Lease payments are discounted using the incremental interest rate for financial loans.

After the initial recognition date, Arauco, as lessee, recognizes a liability for leases by increasing the book value, so as to reflect the interest over the liability for lease, reducing the amount in order to reflect the payments for leases that have been performed and once again recognizing the book value, so as to reflect the remeasurement and also to reflect the essential fixed payments for leases that have been revised.

Arauco presents the assets by right of use in the Interim Consolidated Statement of Financial Position and are further disclosed in Note 8. Likewise, lease liabilities are presented in the Interim Consolidated Statement of Financial Position and further disclosed in Note 23.

IFRS 16 maintains substantially the accounting requirements of the lessor from IAS 17. Therefore, Arauco has continued to classify its leases as operational or financial, as the case may be.

Income from operating leases in which Arauco is the lessor are recognized on a straight-line basis during the term of the lease. Initial direct costs are added to the book value of the underlying asset and are recognized as expenses during the term of the lease on the same basis as the lease income. Leased assets are included within the statement of financial position, in property, plant and equipment. Arauco did not make adjustments with respect to assets that maintains as a lessor, as a result of IFRS 16 adoption.

When assets are leased under a financial lease, the present value of lease payments are recognized as financial accounts receivable. The difference between the gross receivable and the present value of such amount, is recognized as financial return on capital.

Arauco evaluates the economic nature of the contracts that grant the right to use certain assets, for the purposes of determining the existence of implied leases. In these cases, the Company separates, at the beginning of the contract and based on its relative reasonable values, payments and considerations associated with the lease, from the rest of the elements incorporated into the contract.

q) Biological Assets

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

The measurement of the fair value of the biological assets is determined using a discounted cash flow model. Our cash flow projections include significant judgments and assumptions relating to discount rates, estimated growth of the forests and sales margins. This valuation is performed on the basis of each identifiable farm block and for each type of tree.

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

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

Biological growth and changes in fair value of forestry plantations are recognized in the line item “Other income” in the interim consolidated statements of profit or loss.

r) Income taxes

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

Deferred income tax is recognized using liability method, on the temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated annual accounts. Deferred income tax is determined using tax rates contained in laws adopted as of the date of the financial statements and that are expected to be applicable when the related deferred tax asset is realized, or the deferred income tax liability is settled.

Deferred taxes are recognized in accordance with the standards established in IAS 12 - Income Tax.

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

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

s) Provisions

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

t) Revenue recognition

Revenues are valued at fair value of the consideration received or to be received, derived from them. Arauco analyses and takes under consideration all relevant facts and circumstances to apply the five-step model established under IFRS 15 to customer contracts: (i) identify the contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction price, and (v) recognise revenue. Additionally, Arauco evaluates the incremental costs of obtaining a contract and the costs incurred to comply with a contract. Arauco recognizes revenues when the steps established in IFRS have been satisfactorily complied with.

Accounts receivable are recognized when control over goods or services has been transferred to the customer, because at this point of the time collection is unconditional and the passage of time is only needed to receive payment.

(i) Revenue recognition from the Sale of Goods

Revenue from the sale of goods is recognized when Arauco has transferred to the buyer the significant risks and rewards of ownership of the committed goods, when the amount of revenue can be reliably measured, when Arauco does not retain any managerial involvement over the goods sold and when it is probable that the economic benefits associated with the transaction will flow to Arauco and the costs incurred in respect of the transaction can be measured reliably. Revenue from the sale of goods are recognized when there is no obligation unsatisfied that could affect the customer’s acceptance of the product. The delivery is effective when the products are sent to the specific location, the risks of obsolescence and loss have been transferred to the customer and when Arauco has objective evidence that all acceptance criteria have been satisfied.

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

The structure for recognizing revenue from export sales is based on the 2010 Incoterms, which are the official rules for the interpretation of commercial terms issued by the International Chamber of Commerce.

The main Incoterms used by Arauco are the following:

“CFR (Cost and freight)”, where the company bears all costs including main transportation, until the products arrives at its port of destination. The risk is transferred to the purchaser once the products have been loaded onto the vessel, in the country of origin.

“CIF (Cost Insurance & Freight)”, where the Company organizes and pays for external freight services and some other expenses. Arauco is no longer responsible for the products once they have been delivered to the ocean carrier company.

(ii) Revenue recognition from Rendering of Services

Revenue from the rendering of services is recognized as long as the performance obligation have been satisfied.

Revenue is recognized considering the stage of completion of the transaction at the date of the reporting period, when Arauco has the enforceable right of payment from the rendering of the services.

There is no significant financing component, given that sales are made with a reduced average collection period, which is in line with market practice.

Arauco mainly provides power supply services which are transacted principally in the spot market of the Sistema Eléctrico Nacional (SEN) (“National Electrical System”). According to current regulations, the prices on that market called “Marginal Costs” are calculated by the Coordinador Eléctrico Nacional (CEN) (“National Electrical Coordinator”) and are generally recognized in the period in which the services are rendered.

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

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

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

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

u) Minimum dividend

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

On September 28, 2021, Arauco update the dividend policy of the Company, establishing that in respect of fiscal year 2021, it will be distributed among the shareholders an amount equivalent to the 40% of the cash income for such year capable of being distributed as dividends, excluding from the calculation of such cash income the extraordinary benefits that the Company will obtain, through its subsidiary Forestal Arauco S.A., for the sale of several real estate to Vista Hermosa Inversiones Forestales SpA, a transaction that was informed to the stock market through a Material Fact (Hecho Esencial). For the following fiscal years, it will be distributed to the shareholders an amount equivalent to the 40% of the cash income of each fiscal year, capable of being distributed as dividends. In any event, the Board of Directors will be able to distribute and pay interim dividends to the shareholders, as long as it is projected a year end with positive financial results and the availability of cash of the Company permit it so.

v) Earning per share

Basic earnings per share are calculated by dividing the net profit for the period attributable to the parent company by the weighted average number of ordinary shares outstanding during the period, excluding the average number of shares in the Company held by a subsidiary, if such circumstance exists. Arauco has not performed any type of transaction with a potential dilutive effect that would cause diluted earnings per share to be different from basic earnings per share.

w) Impairment

Non-financial Assets

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

A previously recognized impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount however a reversal of an impairment loss shall not exceed the carrying amount that would have been determined (net of amortization or depreciation) had no impairment loss been recognized for the asset in prior years.

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

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

Goodwill

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

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

Amounts in thousands of U.S. dollars, except as indicated

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

Financial Assets

At the end of each reporting period, an assessment is performed in order to identify whether there is any objective evidence that a financial asset or a group of financial assets may have been impaired.

An allowance for doubtful accounts is established based on a measurement of expected losses using a simplified approach.

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

x) Employee Benefits

Arauco constitutes labor obligations for severance payable in all circumstances for certain of its employees with at least 5 years of work in the Company, based on the terms of the staff’s collective and individual bargaining agreements.

The related provision is an estimate of the years of service to be recognized as a future labor obligation liability, in accordance with contracts between Arauco and its employees and pursuant to actuarial valuation criteria for this type of liability. This post-employment benefit is considered a defined benefit plan.

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

Actuarial gains and losses are recognized in other comprehensive income in the year they are incurred.

These obligations are related to post-employee benefits in accordance with current standards.

y) Employee Vacations

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

This obligation is presented in line item “Trade and other current payables” in the interim consolidated statements of financial position.

a) Standards, interpretations and amendments that are mandatory for the first time for annual periods beginning on January 1, 2021:

Amendments and improvements	Content	Mandatory application for annual periods beginning on or after
IFRS 9, IAS 39, IFRS 7, IFRS 4 y IFRS 16	Reference interest rate reform (IBOR). These amendments provide specific simplifications regarding reference rate reform. The Phase 2 amendments address issues that arise from the implementation of the reforms, including the replacement of one benchmark with an alternative one.	January 1, 2021
IFRS 16	Lease concessions As a result of the coronavirus (COVID-19) pandemic, rent concessions have been granted to lessees. In May 2020, the IASB published an amendment to IFRS 16 that provided an optional practical expedient for lessees from assessing whether a rent concession related to COVID-19 is a lease modification. On 31 March 2021, the IASB published an additional amendment to extend the date of the practical expedient from 30 June 2021 to 30 June 2022. Lessees can elect to account for such rent concessions in the same way as they would if they were not lease modifications. In many cases, this will result in accounting for the concession as variable lease payments in the period(s) in which the event or condition that triggers the reduced payment occurs.	January 1, 2021

The amendments above do not have an impact on Arauco Interim Consolidated Financial Statements during its initial application period.

Arauco estimates that the adoption of the standards, amendments and interpretations described above will not have a significant impact on Arauco’s Consolidated Financial Statements during its initial application period.

NOTE 2. ACCOUNTING POLICIES, CHANGES IN ACCOUNTING ESTIMATES

Changes to accounting policies

On January 1, 2021, we discontinued the reporting of our forestry operations as a business segment, and included those operations as part of the pulp segment. This is in line with Arauco’s current reality and with the way in which the management views the progress of the business. Thus, the new segments are: Pulp and and wood products, which demonstrates Arauco’s focus on its end customers.

The comparative information in the tables in Note 24 Reportable Segments has been restated as of December 31, 2020 and September 30, 2020 due to the merger of the pulp and forestry businesses. This reformulation of the Company’s segments did not produce changes in Arauco’s Consolidated Financial Statements (Statement of Financial Position, Statement of Income, Statement of Comprehensive Income, Statement of Changes in Equity, Statement of Cash Flows and Notes to the statements financial statements, except for the Note 24).

Changes to accounting estimates

As of September 30, 2021, there have been no changes in the methodologies for calculating the accounting estimates with respect to the 2020 financial year.

NOTE 3. DISCLOSURE OF OTHER INFORMATION

NOTE 5. CASH AND CASH EQUIVALENTS

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

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

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

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

The tax rates applicable in the countries in which Arauco operates are 27% in Chile, 35% in Argentina and Mexico, 34% in Brazil, 25% in Uruguay and 21% in the United States (federal tax).

In 2021, Argentinian Republic published in the Official Gazette of Argentina the law No. 27,630, which replaced the fixed rate paid by Argentine companies on their corporate income tax periods starting in 2021. It provides a progressive scale of rates, where a 25% rate will be applied to companies with a net taxable income of up to 5,000,000 Argentine pesos (AR$) (approximately ThU.S.$ 51 as of September 30, 2021), a 30% rate will be applied to companies with a net taxable income ranging between AR$ 5,000,000 and AR$ 50,000,000 (approximately ThU.S.$ 506 as of September 30, 2021), and a 35% rate will be applied to companies with a net taxable incomes surpassing AR$ 50,000,000. This new regulation generated a loss of ThU.S.$ 49,000 in Arauco Argentina S.A. in income tax. The rate applied to Arauco Argentina S.A. in 2020 was 30%.

The depreciation expense for the period ending September 30, 2021 and 2020 is as follows:

	January - September				July - September
	2021		2020		2021		2020
Depreciation for the year	ThU.S.$		ThU.S.$		ThU.S.$		ThU.S.$

Other expenses		372		1,885		153		284
Total		314,881		315,793		101,200		107,371

Depreciation charged to profit or loss statement differs from the movement of the period for Property, Plant and Equipment. This is mainly due to the periodic cost processes in which a portion of the depreciation charge remains in Inventories. Furthermore, this deviation is also affected by the conversion differences corresponding to companies that use a functional currency other than U.S. dollars.

The useful lives of property, plant and equipment are estimated based on the expected use of the assets. The average useful lives by asset class are as follow:

	Years of Useful Life (Average)
Buildings		58
Plant and equipment		30
Information technology equipment		8
Fixtures and fittings		28
Motor vehicles		7
Other property, plant and equipment		14

NOTE 17. IMPAIRMENT OF ASSETS

As a result of current market conditions in the United States generated by the decrease in prices, the impairment tests carried out at the CGU yielded an impairment provision of ThU.S.$ 14,918 relating to Property, Plant and Equipment and spare parts from Inventories corresponding to facilities of wood products in United States. For these calculations we used a discount rate of 8.7%. In the 2021 period, provisions associated with assets sold and recovered were reversed for a total of ThU.S.$ 10,911.

In addition, due to the modernization and expansion project of the Arauco Mill (Proyecto de Modernización y Ampliación de la Planta Arauco, or MAPA Project), as of September 30, 2021, we recorded an impairment provision due to a reduction in the useful lives for the CGU Line 1 of Arauco Mill (Pulp business) in an amount of ThU.S.$ 7,712 (ThU.S.$ 46,577 as of December 31, 2020). For this calculation, we used a discount rate of 6.1%. The Line 1 of the Arauco mill will be permanently shut down upon completion of the MAPA project.

Both impairment provision charges are presented in the consolidated statement of profit or loss under Other expenses and they constitue the main changes in the total CGU impairment provision as shown below:

Goodwill

Goodwill is allocated to the groups of cash-generating units that are expected to benefit from the synergies of the combination.

At the date of these interim consolidated financial statements, the balance of goodwill is ThU.S.$ 58,105 (ThU.S.$ 59,567 on December 31, 2020), as shown below:

Of the total of goodwill, ThU.S.$ 40,791 (ThU.S.$ 40,793 as of December 31, 2020) were generated by the acquisition of “Flakeboard” (currently Arauco Canada Ltd.), a company that, directly and/or through its subsidiaries, possesses and operates 7 panel plants, for which Arauco acquired and paid, on September 24, 2012, the price of ThU.S.$ 242,502 for the 100% interest ownership. The remaining balance of ThU.S.$ 732 corresponds to the acquisition of Prime-Line Inc, on September 1, 2019, for which Arauco North America Inc, a subsidiary of Arauco Canada Ltd. paid ThU.S.$ 18,880 for all the shares of said company.

The recoverable amount for Flakeboard’s cash generating unit was determined based on the calculations of its value in use, and this calculation was made using cash flow projections covering a 7-year term, a period time, which is considered to represent the cyclicality of the business performance, applying a nominal discount rate of 7% which reflects current market assessments for the wood products segment in North America.

The investment in the panel plant in Pien, Brazil generated a goodwill of ThU.S.$ 16,582 (ThU.S.$ 17,357 as of December 31, 2020).

The recoverable amount for the Pien plant’s cash generating unit was determined based on the calculations of its value in use, and this calculation was made using cash flow projections covering a 5-year term based on the operational plan approved by the Administration, applying a 7.4% nominal discount rate that reflects current evaluations for the panel segment in Brazil.

As of September 30, 2021 and as of December 31, 2020, the carrying value of the goodwill of the plants did not exceed their recoverable value, and therefore there was no need to recognize impairment losses.

Sensitivity analysis on discount rate was made and no impairment provision was determined.

NOTE 18. PROVISIONS, CONTINGENT ASSETS AND CONTINGENT LIABILITIES

The contingent liabilities for outstanding litigations are as follows:

Celulosa Arauco y Constitución S.A.

1. On August 25, 2005, the Chilean Servicio de Impuestos Internos (the “Chilean IRS”) issued tax resolutions No. 184 and No. 185 of 2005, and objected certain income tax returns made by Arauco on April 16, 2001 and October 31, 2001, and furthermore, requested the reimbursement of the amounts returned in connection with tax losses, along with the amendment of the FUT (Tax Profits Fund) Registry balance. In consideration to the foregoing, the above mentioned tax resolutions ordered the restitution of the historical amount as of October 31, 2002 of $4,571,664,617 Chilean Pesos (equal to ThU.S.$ 5,631 as of September 30, 2021). 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 above mentioned tax resolutions No. 184 and 185 of 2005. The RAF was resolved on January 9, 2009 by the Chilean IRS, partially sustaining the Company’s request, granting a discount to the total amount of $1,209,399,164 Chilean Pesos (equal to ThU.S.$ 1,490 as of September 30, 2021), resulting in a total disputed amount as of October of 2002 of $3,362,265,453 Chilean Pesos (equal to ThU.S.$ 4,141 as of as of September 30, 2021) plus fines and interests. On February 19, 2010, the Court acknowledged receipt of the Company’s request.

On September 26, 2014, Arauco requested the submission of this claim to the competent jurisdiction of the new Tax and Customs Courts. On October 10, 2014, Arauco’s request was granted. Currently the action is being considered by these new Courts under the Docket No. RUC 14-9-0002087-3. On September 20, 2017, the Court issued its first instance decision confirming the liquidations.

On October 12, 2017, Arauco challenged the decision through an appeal, requesting the Court of Appeals of Santiago to revoke the first instance decision and uphold Arauco’s claim instead. On June 29, 2018, the Court of Appeals of Santiago issued a ruling on appeal, confirming the first instance decision. On July 19, 2018, Arauco lodged a cassation appeal based on formal and substantial flaws before the Supreme Court. (case file 24,758-2018).

On June 21, 2019, Celulosa Arauco y Constitución S.A. filed a claim before the Constitutional Court to declare the legal provision contemplated under section 53, paragraph 3 of the Tax Code unconstitutional and, as a consequence, inapplicable.

On October 29, 2019 the Constitutional Court accepted the claim filed by Celulosa Arauco y Constitución S.A., finding unconstitutional and declaring the inapplicability of section 53, paragraph 3 of the Tax Code in the context of the proceeding “Celulosa Arauco y Constitución S.A. with SII Large taxpayers”, which is in the Supreme Court docket as a result of a cassation appeal (based on form and content) under case file 24,758-2018.

Currently, the case is related in the Supreme Court.

Considering that the Company’s position is based on solid legal grounds, there is a reasonable margin for obtaining a favorable result for the Company and therefore as of as of September 30, 2021, Arauco has not made any provision whatsoever in connection with this contingency.

2. Through Res. Ex. N° 1 issued by the Superintendence of the Environment (“SMA”) on January 8, 2016, notified on January 14, 2016, the SMA formulated 11 charges against the Company, due to alleged breaches of certain Environmental Qualification Resolutions for the Valdivia Plant and of DS No. 90/2000. The 11 charges were classified as follows by the SMA: 1 critical, 5 severe, 5 minor.

On February 12, 2016, the Company submitted its defenses.

On December 15, 2017, the Superintendence of the Environment issued Exempted Resolution No. 1,487, closing the punitive administrative proceeding, absolving the company with regards to one of the charges and convicting for other 10 charges, applying a fine of 7,777 UTA (equal to ThU.S.$ 6,050 as of September 30, 2021). On December 22, 2017, the Company submitted a motion for reconsideration regarding Exempted Resolution No. 1,487, before the SMA, requesting that we be absolved of all infringements, with the exception of the charge specified under number 7 (late submission of the water quality report regarding the Cruces river). On March 23, 2018, the reconsideration appeal lodged by the company was rejected. On April 5, 2018, a judicial claim was submitted before the Third Environmental Court. On November 12, 2018, the case was in agreement, and the Minister Ms. Sibel Villalobos Volpi was appointed to draft the ruling.

On February 11, 2020 the judgment of the Third Environmental Court was notified, which partially accepted the legal claim of the Company, only as to the inadequate severity qualification of one of the charges. On February 28, 2020, both the Company and the SMA submitted cassation appeals based on form and content, to be heard and resolved by the Supreme Court.

Considering that the Company’s position is based on solid legal grounds, there is a reasonable margin for obtaining a favorable result for the Company, and therefore as of September 30, 2021, Arauco has not made any provision whatsoever in connection with this contingency.

Celulosa Arauco y Constitución S.A., Forestal Arauco S.A., Maderas Arauco S.A. and Servicios Logísticos Arauco S.A.

5. On May 11, 2020, Forestal Arauco S.A. was notified of a lawsuit of declaration of mere certainty filed against it by the company “Agrícola, Forestal, Transportes y Inversiones El Quillay SpA”, before the Court of Constitución (Case C-323-2020), in which the plaintiff claims that the property called “Predio que formaba parte de la Hijuela Sur Poniente, de la Hijuela Sur del Fundo Quivolgo” owned by Forestal Arauco S.A. would actually have an area of 498 hectares, and, consequently, that the defendant lacks the right of ownership over a portion of land corresponding to 1,768.20 hectares of said property.

Arauco Argentina S.A.

Pursuant to law No. 25,080, the former Secretary of Agriculture, Livestock, Fishing and Foodstuffs, the enforcement agency referred to in the law approved, by Res. No. 952/2000, the forestry and industrial-forestry projects submitted by Arauco Argentina S.A. In the context of these projects, the Company afforested: 1) 4,777 hectares during 2000, in observance of its committed yearly plan; and 2) 23,012 hectares between 2000 and 2006 as a part of the multi-year afforestation plan. Likewise, a sawmill was built with installed capacity to produce 250,000 m3 of sawn timber per year.

On January 11, 2001, Arauco Argentina S.A. submitted an expansion for the approved industrial-forestry project. The expansion was approved via Res. No. 84/03 issued by the former Secretary of Agriculture, Livestock, Fishing and Foodstuffs. In accordance with the assumed obligations, the Company built a MDF board (panels) plant and afforested 8,089 hectares between 2001 and 2006.

Additionally, the Company has filed yearly forestry plans between years 2007 and 2019 for its local operations in the provinces of Misiones and Buenos Aires.

On March 25, 2019, the Secretary of Agriculture, Livestock and Fishing approved the resolution No. 2019-55-APN-SECAGYP#MPYT, approving the annual forestry plan for 2007. In addition, said organism through the resolution No. 2019-114-APN-SECAGYP#MPYT approved the annual forestry plan for 2009 on June 12, 2019, and through the resolution No. 2019-228-APN-SECAGYP#MPYT approved the annual forestry plan for 2008 on November 29, 2019. For this reason, Arauco Argentina S.A. may compute the exemption in the income tax related to the forest appraisal on the plantations to be harvested from the lands included in those plans as from the 2019 period.

In March 2005, Note No. 145/05 of the Subsecretary of Agriculture, Livestock and Afforestation suspended the benefit that exempted Arauco Argentina S.A. from paying export duties under Law No. 25,080. This measure is currently under discussion by the

Company. On November 8, 2006, the V Chamber of the National Appeals Court for Adversarial Administrative and Federal Matters issued a ruling ordering Arauco Argentina S.A. to continue to enjoy an exemption from paying the exportation duties, in the same manner and scope it had prior to the suspension ordered by Note No. 145/05, if the clearance of merchandise is performed pursuant to the guarantee regime established in article 453, subsection a) of the Customs Code, for the exempted tax obligation. The judicial measure became effective beginning on March of 2007 by collateralization through the granting of bond (caution) policies for each shipment permits exempted from payment of export duty. The company maintains an assignment of funds equivalent to $ 2,160,896,000 Argentine Pesos (ThU.S.$ 21,887 as of September 30, 2021) for guaranteed export duties between 2007-2015, which appears under not current provisions. Additionally, the Company filed a restitution claim for a total amount of ThU.S.$ 6,555, plus interests accrued from the service of the claim, corresponding to export duties between March 2005 and March 2007, as a result of the application of Note 145/05 issued by the Undersecretary of Agriculture, Livestock and Afforestation. The Company’s claim is being heard under case file No. 21830/2006 before the Federal Contentious Administrative Court No. 4. On October 28, 2019, a judgment of first instance was issued in said case, rejecting the claim and imposing the litigation costs on Arauco. Against that judgment, the Company filed an appeal and expressed the corresponding arguments in December 2019. On November 5, 2020, the Chamber of Appeals considered the arguments made by Arauco and determined that a final ruling will be issued in the case.

On the other hand, Arauco Argentina S.A. currently has a guarantee at an amount of $435,952,315 Argentine Pesos (ThU.S.$ 4,416 as of September 30, 2021) in favor of the Secretary of Agriculture, Livestock and Fishing.

Arauco Argentina S.A. believes that it has complied with all of the obligations imposed upon it by the system set forth under Law No. 25.080.

Arauco do Brasil S.A.

The Federal Reserve of Brazil contested the amortization of goodwill resulting from acquisitions of Placas do Paraná, Tafibrás, Tafisa (now, Arauco do Brasil S.A.) y Dynea.

On July 20, 2015, Arauco do Brasil was notified of the first-level administrative ruling which partially upheld the infringement. Against this ruling, a Voluntary Appeal was filed seeking to revoke the Infringement Notice before the Brazilian Administrative Tax Council (Conselho Administrativo de Recursos Fiscais de Brasil or “CARF”), which is the second administrative level.

The CARF’s decision was issued on May 16, 2017 and took into consideration certain arguments presented by the Company regarding the premium but preserving other charges. On September 27, 2018, Arauco do Brasil was notified of the CARF’s decision, for which Arauco do Brasil S.A. filed an appeal for declaration embargoes, to elicit clarifications from the CARF regarding certain points of the decision. On January 25, 2019, the CARF ruled that there were no clarifications or omissions to be made and, consequently, granted a term for filing the last remedy within the administrative realm (“Special Remedy”). This Special Remedy was submitted before the Upper Chamber of Fiscal Remedies of the CARF (CSRF) on February 11, 2019, reiterating the Company’s defense allegations regarding the matters and charges that remained in such process.

On August 28, 2020, the Company was served with an intermediate decision in Grievance of Instrument, issued by CARF that divided the claim into two parts:

(i) One part that remains awaiting the administrative decision in Special Remedy to the CSRF (the issue of the isolated fine of 50% and interests) with the estimated amount of R$ 29,250,417 (equivalent to ThU.S.$ 5,357 as of September 30, 2021) and that amount will be added interests and readjustments as of January 31, 2019 until the administrative discussion is finished.

(ii) Second part that closes the administrative discussion (Comment of the contractual expenses deducted in the purchase of Tafisa; Comment of interests and legal expenses on debts paid in the amnesty program; payment of IRPJ and lower CSLL in the second part of 2010). Regarding this second part, the amount of R$ 31,774,176 (equivalent to ThU.S.$ 5,819 as of September 30, 2021) and to this amount interests and readjustments will be added as of August 28, 2020 until the final decision of the discussion court initiated on September 23, 2019, to continue answering that part of the claim. Thus, we enter with a Tax Debt Cancellation Action and we are introducing a guarantee for the suspension of any collection an to obtain the Certificates of Tax Compliance until the final decision of the trial. Currently we are starting to produce expert evidence in the case.

Considering that the Company’s position is based on solid legal grounds, there is a reasonable margin for obtaining a favorable result for the Company and therefore, as of September 30, 2021, Arauco has not made any provision whatsoever in connection with this contingency.

At the closing date, there are no other contingencies in which the Companies act as obligor, that may significantly affect their financial, economic or operational conditions.

Provisions recorded as of September 30, 2021 as of December 31, 2020 are as follows:

Amounts in thousands of U.S. dollars, except as indicated

NOTE 20. BIOLOGICAL ASSETS

Biological assets comprise forestry plantations, mainly radiata and taeda pine, and to a lesser extent eucalyptus. The plantations are located in Chile, Argentina, Brazil and Uruguay.

As of September 30, 2021 Arauco has a total surface of 1.6 million hectares of which 936 thousand hectares are used for forestry planting, 479 thousand hectares are native forest, 107 thousand hectares are used for other purposes and 72 thousand hectares not yet planted. Lands correspondening to native forest, lands used for other purposes and lans not yet planted are presented in Property, Plants & Equipments, Forest plantations are presented in Biological Assets.

For the period ended September 30, 2021, the production volume of logs totaled 15.4 million m3 (13.7 million m3 as of September 30, 2020).

Measurements of fair value of Arauco’s biological assets are classified as Level 3, due to the fact that inputs are not observable. However, this information reflects the assumptions that market participants would use in pricing the asset, including assumptions about risk.

These unobservable inputs were developed using the best information available and includes internal data from Arauco. These unobservable inputs can be adjusted if the available information indicates that other market participants would use different information or there is something specific in Arauco that is not available to other market participants.

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

• Arauco uses discounted expected future cash flows of its forest plantations, which are based on a harvest projection date for all existing plantations.

• Current forestry plantations are projected based on a net volume that will not decrease, with a minimum growth equivalent to the current supply demand.

• Future plantations are not considered.

• The harvest of forestry plantations supplies raw materials for all other products that Arauco produces and trades. By directly controlling the development of forests that will be processed, Arauco ensures high quality timber for each of its products.

• Expected cash flows are determined in terms of harvest and expected sale of forestry products, associated with the demand from the Company’s own industrial centers and sales to third parties at market prices. Sales margin of the different products that are harvested in the forest is also considered in the valuation. The changes in the value of the plantations pursuant to the criteria defined above are accounted for in the results for the fiscal year, as established in IAS 41. These changes are presented in the Interim Consolidated Statements of Profit or Loss under the line item Other income per function, which as of September 30, 2021 amounted to ThU.S.$ 124,531 (ThU.S.$ 130,004 as of September 30, 2020). The appraisal of biological assets resulted in a greater cost of the lumber sold in comparison to the real incurred cost, which is presented included in the cost of sales which as of September 30, 2021 amounted to ThU.S.$ 160,640 (ThU.S.$ 146,128 as of September 30, 2020).

Unaudited Interim Consolidated Financial Statements

September 30, 2021

Amounts in thousands of U.S. dollars, except as indicated

• Forestry plantations are harvested according to the needs of Arauco’s production plants.

• The discount rates used are 5.5% in Chile, 6.7% Brazil, 16.2% in Argentina and 6.5% in Uruguay.

• It is expected that prices of harvested timber are constant in real terms based on market prices.

• Cost expectations with respect to the lifetime of the forests are constant based on estimated costs included in the projections made by Arauco.

• The average crop age by species and country is:

	Chile		Argentina		Brazil		Uruguay
Pine		24		15		15		—
Eucalyptus		12		10		7		10

The following table sets forth changes in fair value of biological assets considering variations in significant assumptions considered in calculating the fair value of the assets:

		ThU.S.$
Discount rate	0.5		(149,083	)
	-0.5		159,429
Margins (%)	10		442,060
	-10		(442,060	)

The significant unobservable input data used in the measurement of the fair value of biological assets are discount rates and sales margins of the different products that are harvested from the forest. Increases (decreases) in any of these input data considered in isolation would result in a smaller or greater fair value measurement.

The adjustment to fair value of biological assets minus sale costs is recorded in the Interim Consolidated Statements of Profit or Loss, under the line item Other Income or Other Expenses, depending on whether it corresponds to profits or losses.

Forestry plantations classified as current Biological assets are those to be harvested and sold within twelve months after the reporting period.

The Company has contracted fire insurance policies for its forestry plantations, which in conjunction with the Company’s resources, allow risks to be minimized.

As of the date of these Interim Consolidated Financial Statements, there are no committed disbursements for the acquisition of biological assets.

Detail of Biological Assets Pledged as Security

As of September 30, 2021, there are no forestry plantations pledged as security.

NOTE 21. ENVIRONMENTAL MATTERS

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 into practice in everyday company operations.

23.2 Fair Value Hierarchy of Financial Assets and Liabilities

The assets and liabilities measured at fair value in the interim consolidated statements of financial position as of September 30, 2021, have been measured based on the valuation methodologies provided in IFRS 13. The methodologies applied for each financial instrument are classified according to their hierarchy as follows:

• Level 1: Securities or quoted prices in active markets for identical assets and liabilities

• Level 2: Inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level 3: Inputs for the assets or liabilities that are not based on observable market data (unobservable inputs).

Fair Value	September 2021 ThU.S.$		Level 1 ThU.S.$		Level 2 ThU.S.$		Level 3 ThU.S.$

At the closing date of these interim consolidated financial statements, there have been no transfers between the different hierarchy levels.

23.3 Explanation of the valuation of Financial Instruments.

Cash and cash equivalent and accounts receivable

The carrying amount of accounts receivable, cash and cash equivalents (including mutual funds), and other financial assets and liabilities approximate their fair value due to the short-term nature of such instruments.

Derivative financial instruments

Arauco’s current derivatives are valued under the cash flow discount method. These flows are discounted at the rate applicable according to the transaction’s and counterparties’ risk, using an internal methodology based on the information obtained from Bloomberg.

Given thath our cross-currency swaps correspond to future flows in UF, U.S. dollars and Euros, Arauco calculates the current value of such flows by using the UF zero coupon curve, Dollar zero coupon and the Euro zero coupon.

The fair value of the interest rate swap contracts is calculated by reference to the rate differential between the agreed upon rate and the market rate as of the end date of these financial statements.

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

The fair value of zero cost collar contracts is calculated by reference to the price differential between the agreed price range and the market price of the hedge’s object.

The counterparty risk uses the Z-Spread obtained from the curve of the bonds issued by counterparties, and they are deducted from each flow as appropriate.

Financial Liabilities

The fair value of bonds issued was determined with reference to quoted market prices as they have standard terms and conditions.

The fair value of bank borrowings was determined based on discounted cash flow analysis applying the corresponding discount yield curves to the remaining term to maturity.

Disclosures of the fair value of financial liabilities at amortized cost are determined via the use of discounted cash flows, calculated over variables of the observable markets as of the date of informing the interim consolidated financial statements, and correspond to Level 2 of the fair value hierarchy.

The following table shows the compliance with the financial covenants (level of indebtedness, detailed in section 23.9.3), for the bonds issued prior to the year 2015, as required by domestic indentures (Chile):

Arauco applies the simplified approach regarding the expected losses from commercial debtors, which allows for the use of an estimate of expected credit losses over the instrument’s lifespan for all commercial accounts receivable. In order to establish this estimate, the commercial debtors have been grouped in relation to the corresponding risks for sales conditions as well as for tranches, including clients that are up-to-date or in default.

Explanation regarding the Sales Risk with Letters of Credit

The sales with letters of credit mainly occur in markets in Asia and the Middle East. Periodically, a credit assessment is conducted regarding the banks that issue the letters of credit with the purpose of obtaining their score over the basis of risk-qualification ratings, country-specific risk and financial statements. The decision of approving the issuing bank or asking for confirmation of the letter of credit is made in consideration to this assessment.

Explanation of the Sales Risk with Credit Line

Sales on credit are subject to the credit limit for each customer. The approval or rejection of a credit limit for all term sales is conducted by the Corporate Credit Sub-Division, as well as by the Credit and Collections area for North America, Brazil and Argentina, which report to the Corporate Finance Division. The regulations and procedures applicable for the correct control and risk management over the sales on credit are ruled by the Credit Policy.

A procedure that must be applied by all the companies of the Arauco group has been established for the approval and/or modification of client credit lines. Credit line requests are entered to the SAP that analyzes all available information. Afterwards, the same are either approved or rejected in each one of the internal committees of each company belonging to the Arauco group, depending on the maximum amount authorized by the Credit Policy. Lines of credit are renewed during this internal process on a yearly basis.

All sales are automatically controlled by a credit verification system, which has been configured to block any orders from clients who are delinquent in a given percentage of a debt and/or from clients whose line of credit, as of the time of the product’s shipping, has been exceeded or is overdue.

In order to minimize the credit risk for term or Open Account sales, it is Arauco’s policy to take out insurance to cover the export sales of companies Celulosa Arauco y Constitución S.A., Maderas Arauco S.A., Forestal Arauco S.A., Arauco Argentina S.A., and Arauco do Brasil S.A., as well as the domestic sales of Arauco Europe Coöperatief U.A., Arauco Argentina S.A., Araucomex S.A. de C.V., Arauco Industria de México, S.A. de C.V., Arauco Colombia S.A., Arauco Perú S.A., Arauco North America, Inc., Arauco Canada Ltd., Celulosa Arauco y Constitución S.A., Maderas Arauco S.A., Arauco Florestal Arapoti, Arauco Forest Brasil S.A., Arauco do Brasil S.A. and Arauco Industria de Paineis Ltda. Arauco works with credit insurance company Euler Hermes World Agency (Aa3 rating, as per risk rating companies Moody’s and AA by S&P). The company grant a 90% coverage over the amount of each invoice, without deductibles, for registered clients and of 90% for non-registered clients (*).

(*) Non-registered clients are those whose lines are under ThU.S.$ 100 (equivalent currency of their invoicing) of the credit sales for all companies in the Arauco group that have a valid insurance policy. The top lines are from nominated clients.

As another way of minimizing risk and supporting a line of credit approved by the Credit Committee, Arauco holds guarantees such as mortgages, pledges, Standby letters of credit, bank performance bonds, checks, promissory notes, loans or any other that could be required under the laws of each country. The total amount held in guarantees amounts to ThU.S.$ 105,419, effective as of September 30, 2021, as summarized in the following chart. The procedure for guarantees is regulated by Arauco’s Policy on Guarantees, whose purpose is to control their accounting, due date and custody.

The maximum exposure to credit risk is limited to the value at amortized cost of the Debtors’ account for sales registered as of the date of this report, minus the percentage of sales insured by the aforementioned credit insurance companies and the guarantees granted in favor of Arauco.

In summary, the open account debt covered by the various insurance policies and guarantees amounts to 95.5% and, therefore, Arauco’s portfolio exposure amounts to 4.5%.

Unsecured receivables		22,907		4.5	%

(*) Insured Debt is deemed to be the portion of accounts receivable that is covered by a credit company or by guarantees such as standby letters of credit, mortgages, performance bonds, among others

Investment Policy:

Arauco has an Investment Policy which identifies and limits the financial instruments and the entities into which the Arauco companies, in particular Celulosa Arauco y Constitucion S.A., are authorized to invest. 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 apply to short and long-term debt, and will be for specific investments made through other companies where authorization is required from the Chief Financial Officer.

For financial instruments, the only permitted investments are fixed income investments with adequate liquidity. Each instrument has defined classifications and limits, depending on duration and type of issuer.

Regarding intermediaries (such as banks, securities brokers and dealers of mutual funds that are bank affiliates), a scoring methodology is used to determine the relative degree of risk of each intermediary based on their financial position and assign score points that result in a credit risk rating to each intermediary. Arauco uses this scoring system to determine its investment limits for each intermediary.

The required information to evaluate the various criteria are obtained from published financial statements from the banks under evaluation and from the credit risk ratings of short and long-term debt securities obtained from rating agencies authorized by the Superintendence of Banks and Financial Institutions (Fitch Ratings Chile, Humphreys and Feller Rate).

Any necessary exceptions regarding investment limits in each particular instrument or entity must have the authorization from Arauco’s Chief Financial Officer.

23.10.2 Type of Risk: Liquidity Risk

Description

This risk corresponds to Arauco’s ability to fulfill its financial obligations upon maturity.

Explanation of Liquidity Risk Exposure and How This Risk Arises

Arauco’s exposure to liquidity risk is mainly from its obligations to bondholders, banks and financial institutions, creditors and other payables. Liquidity risk may arise if Arauco is unable to meet the net cash flow requirements, which sustain its operations under both normal and exceptional circumstances.

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

The Corporate Financial Management Division monitors on an ongoing basis the Company’s cash flow forecasts based on short and long-term forecasts and available financing alternatives. In order to manage the risk level of financial assets, Arauco follows its investment policy.

The following tables detail Arauco’s liquidity analysis for its financial liabilities as of September 30, 2021 and as of December 31, 2020. The tables have been drawn up based on the contractual undiscounted cash outflows and their remaining contractual maturities.

Unaudited Interim Consolidated Financial Statements

September 30, 2021

Amounts in thousands of U.S. dollars, except as indicated

Regarding the Libor rate and its discontinuity, at the end of September 2021 Arauco maintains 5.69% of its total debt at said rate and it is not estimated that the effect of its elimination will be material. Additionally, Arauco maintains interest rate derivatives for 90% of its Libor rate based debt.

Guarantees

As of the date of these interim consolidated financial statements, Arauco has financial assets of approximately MU.S.$ 48 that have been pledged to third parties (beneficiaries), as direct guarantee. If Arauco does not fulfill its obligations, the guarantors could execute the guarantees.

As of September 30, 2021, the total assets pledged as an indirect guarantee were MU.S.$ 393. In contrast to direct guarantees, indirect guarantees are given to secure obligations assumed by a third party.

On September 29, 2011, Arauco entered into a Security Agreement under which it granted a non-joint guarantee limited to 50% of the obligations of the Uruguayan companies (joint ventures) Celulosa y Energía Punta Pereira S.A. and Zona Franca Punta Pereira S.A., under the IDB Facility Agreement in the amount of up to MU.S.$ 454 and the Finnevera Guaranteed Facility Agreement in the amount of up to MU.S.$ 900. Both loan agreements were signed with the International Development Bank. Such guarantee is included in the table below, under indirect guarantees.

23.10.3 Type of Risk: Market Risk – Exchange Rate

Description

Market risk arises from the probability of being affected by losses from fluctuations in currencies exchange rates in which assets and liabilities are denominated, in a functional currency other than the functional currency of Arauco.

Explanation of Currency Risk Exposure and How This Risk Arises

Arauco is exposed to the foreign currency risk from currency fluctuations arising from sales, purchases and obligations undertaken in foreign currencies, such as the Chilean Peso, Euro, Brazilian Real or other foreign currencies. In the case of significant exchange rate variations, the Chilean Peso is the currency that represents the main currency risk. See Note 11 for details assets and liabilities classified by currency.

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

Arauco performs sensitivity analyses to measure the effect of this variable on equity and net result.

Sensitivity analysis considers a variation of +/- 10% of the exchange rate over the Chilean Peso. This fluctuation range is considered possible given current market conditions as of the date of these financial statements. 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 a change in the net income year after tax +/- 0.8% (equivalent to ThU.S.$ -/+ 6,534), and +/- 0.05% of equity (equivalent to ThU.S.$ -/+ 3,921).

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 as of the date of these financial statements. 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 +/- 0.26% (equivalent to ThU.S.$-/+$ 2,107) and a change on the equity of +/- 1.18% (equivalent to ThU.S. -/+$ 91,948).

23.10.4 Type of Risk: Market Risk – Interest rate risk

Description

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

Explanation of Interest Rate Risk Exposure and How This Risk Arises

Arauco is exposed to risks due to interest rate fluctuations for bonds issued, bank borrowings and financial instruments that bear interest at a variable rate.

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

Arauco completes its risk analysis by reviewing its exposure to changes in interest rates. As of September 30, 2021, 5.8% our financial debt accrues interest at variable rates. A change of +/- 10% in the interest rate is considered a possible range of fluctuation. Such market conditions would affect the income after tax at rate of +/- 0.005% (equivalent to ThU.S.$-/+ 39) and +/- 0.0003% (equivalent to ThU.S.$-/+ 23) on equity.

23.10.5 Type of Risk: Market Risk – Price of Pulp Risks

Description

Pulp prices are determined by world and regional market conditions. Prices fluctuate based on demand, production capacity, commercial strategies adopted by large-scale forestry companies, pulp and paper producers and by the availability of substitutes.

Explanation of Price Risk Exposure and How This Risk Arises

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

As of September 30, 2021, revenue due to pulp sales accounted for 44.4% of total sales. Pulp prices are fixed on a monthly basis in accordance with the market. Forward contracts or other financial instruments are not used for pulp sales.

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

This risk is approached in different ways. Arauco has a team of specialists who perform periodic market and competition analyses, providing tools to analyze and evaluate trends and adjust forecasts. Similarly, Arauco performs price financial sensitivity analysis in order to take the necessary safeguards to confront different scenarios in the best possible manner.

Sensitivity analysis considers a variation of +/- 10% in the average pulp price, a possible fluctuation range given current market conditions at the date of the closing balance. With all other variables constant, a variation of +/- 10% in the average pulp price would mean a variation of +/- 16.9% (equivalent to ThU.S.$-/+ 137,784) on the income for the year after tax and +/- 1.06% (equivalent to ThU.S.$ -/+ 82,671) on equity.

NOTE 26. DISTRIBUTABLE NET PROFIT AND EARNINGS PER SHARE

Distributable net profit

As a general policy, the Board of Directors of Arauco agreed that the net profit to be distributed as dividend is determined based on realized net gains/(losses) of any relevant variations in the value of unrealized assets and liabilities, which are excluded from the calculation of net profit during the period such changes are made.

As a result of the foregoing, for purposes of determining the distributable net profit of the Company, which is the same considered for calculating the minimum dividend required and additional dividend, the following unrealized gains/losses are excluded from the net profit for the year:

NOTE 27. COVID-19

In late December 2019 a notice of pneumonia originating from Wuhan, Hubei province (COVID-19, caused by a novel coronavirus) was reported to the World Health Organization, with cases soon confirmed in multiple provinces in China, as well as in other countries. As of the date of this report, the virus has affected most nations, including Chile, Argentina, Brazil, Uruguay, Mexico, and the United States.

Several measures have been undertaken by governments around the globe, including the use of quarantine, screening at airports and other transport hubs, travel restrictions, suspension of visas, nation-wide lockdowns, closing of public and private institutions, suspension of sport events, restrictions to museums and tourist attractions and extension of holidays, among many others.

In this complex scenario, it is important to highlight that, in March 2020, our industrial activities were declared as essential business by the authorities in most of the countries where we have operations. This has allowed us, as of the date of this report, to maintain the operational continuity in most of our industrial operations, helping to mitigate negative effects on the demand of some of our clients and products. We have implemented health and safety protocols for our workers both in industrial operations and in commercial offices. The measures adopted -such as social distancing, sanitation of the facilities, preventive testing, personnel transportation, home office, among others- are being continuously monitored so that workers have all the necessary protection for the performance of their functions.

Arauco’s commitment is not only with its workers, but also with the communities where we operate. In this regard, we have developed programs aimed at strengthening the capacities of the health system, through massive sanitation and fumigation programs of common spaces in the suburbs where we are present in Chile and delivery of sanitary supplies and essential reagents for 8 thousand diagnostic tests in the Ñuble region. In addition, support has been provided in temperature taking points and sanitary barriers in coordination with authorities; contributuion of hospital equipment and mechanical fans in Curanilahue, Biobío region; support in the implementation of rest areas for hospital personnel and improvements in spaces within hospitals in Chile; and collaborated in research for the development of mechanical fans.

On the other hand, our employees have participated as volunteers to deliver food boxes, as part of the campaign promoted by the CPC to reach the most vulnerable families in the country. This initiative entailed deliverying 5,226 food boxes in 28 communes of Chile, and putting together a network of Arauco Chile seamstresses for the development of reusable masks. Support was also provided, through the Fundación AcercaRedes, to the economy of small producers in Chile and for thereopening of agricultura fairs, applying various sanitation actions and delivering health kits. A network of volunteers was also assembled to support families living in rural areas.

No significant economic impacts have been generated in the operations reflected in Arauco’s financial statements.

All forward-looking statements are based on information available to ARAUCO on the date hereof and ARAUCO does not assume any obligation to update such statements. References herein to “U.S.$” are to United States dollars. Discrepancies in any table between totals and sums of the amounts listed are due to rounding. This report is unaudited. REVENUES US$1,705.1 million ARAUCO’s revenues reached US$1,705.1 million during the third quarter of 2021, a 9.6% increase compared to the US$1,555.6 million obtained during the second quarter of 2021 and a 41.7% increase compared to the third quarter of 2020. NET INCOME US$511.5 million ARAUCO’s net income was US$511.5 million, equivalent to a US$377.6 million or 154.0% increase when compared to the US$201.4 million obtained during the second quarter of 2021, and a US$475.5 million increase compared to the third quarter of 2020. ADJUSTED EBITDA US$922.9 million Adjusted EBITDA reached US$922.9 million, a 69.2% or US$377.6 million increase compared to the US$545.4 million obtained during the second quarter of 2021, and US$632.2 million increase compared to the third quarter of 2020. NET DEBT TO EBITDA 2.00x Net Financial Debt decreased by US$297.0 million or 6.2% compared to the last quarter. Net Financial Debt / LTM Adjusted EBITDA ratio reached 2.00x in this quarter, a decrease compared to 2.97x in the second quarter of 2021 and the 5.43x reached during the third quarter of 2020. CAPEX US$364.5 million CAPEX reached US$364.5 million during this quarter, a US$37.3 decrease when compared to the US$401.8 million from the second quarter of 2021.

3Q 2021 RESULTS Overview ARAUCO´s net income for the third quarter of 2021 was US$511.5 million, an increase of US$310.1 million compared to the second quarter of 2021. This is mainly explained by the closing of the forestry asset sale we announced a few months ago, and also due to a better operational result due to higher average realized prices in our wood products segment, and higher volumes in our pulp segment. This was partially offset by a 14.5% increase in distribution costs. Our Adjusted EBITDA was 69.2% higher than that of the second quarter, reaching US$922.9 million. The Adjusted EBITDA margin increased from 35.1% to 54.1% on a quarterly basis. Net Financial Debt decreased by US$297.0 million or 6.2% compared to the last quarter. Our Net Debt/LTM EBITDA ended up in 2.00x, a decrease when compared to the 2.97x reached during the second quarter of 2021.

3Q 2021 RESULTS Revenues ARAUCO’s revenues reached US$1,705.1 million in the third quarter of 2021, an increase of 9.6% when compared to the previous quarter. This variation is mostly explained by higher revenues in our wood products division, due to an 8.8% increase in average prices. Additionally, revenues for our pulp division increased by 6.9% or US$49.0 million. The following table shows a breakdown of our revenues by business segment: In US$ Million Q3 2021 Q2 2021 QoQ Pulp 760.8 711.9 6.9% Wood Products 944.2 843.6 11.9% Total 1,705.1 1,555.6 9.6% 3Q 2021 Revenue’s breakdown Pulp 44.6% Wood Products 55.4%

3Q 2021 RESULTS Cost of sales Increased by 4.1% or US$36.2 million compared to the second quarter of 2021. This is mostly explained by increases in forestry labor and chemical costs primarily due to the increase in sales volume both in our Pulp and Wood Products segments, partially offset by a decrease in timber costs.

The main significant effects are given by the variation of local currencies in the countries where we have industrial operations, such as the Chilean Peso and the Brazilian Real. Income tax For the third quarter, income tax expenses reached US$169.1 million, US$45.7 million higher than the US$123.4 million of the previous quarter, explained by a better pre-tax result.

3Q 2021 RESULTS Adjusted EBITDA Adjusted EBITDA for the third quarter of 2021 was US$922.9 million, a 69.2% or US$377.6 million increase when compared to the previous quarter. This is mainly explained by the effect on results of the closing of the forestry asset sale announced a few months ago. This effect is contained in our pulp business segment and was of approximately US$229 million. We also saw an increase in our wood products segment Adjusted EBITDA, increasing 33% or US$83.9 million, due mostly to higher average realized prices.

3Q 2021 RESULTS Pulp Business During the third quarter, pulp demand remained stable, with some minor price declines in some markets towards the end of the quarter, due to the low season in the northern hemisphere. Customers in every market, but mainly in Asia, have been affected by the rise in logistics costs, which made them reduce their exports and concentrate in the domestic market. World inventories for both fibers increased between June and August 2021, short fiber increased by 8 days and long fiber by 6 days. Global BCP Shipments China -9.2% Europe 1.2% Other Asia -9.1% USA -2.3% Rest of the World 3.2% Total -4.7% Last 9 months, Jan-Sep 2020 and 2021 BCP stands for Bleached Chemical Pulp. Source: Hawkins Wright. In China, pulp demand started to decline towards the end of the third quarter because mills in all type of industries had to reduce their operating rate or stop their production lines due to the government limiting energy consumption in several provinces in the country. The tissue industry started to improve, with some producers achieving some price increases to their final products. The P&W industry remained relatively stable during the quarter, with some producers trying to implement price increases. Long fiber prices remained steady through the quarter, however, short fiber prices decreased. The spread between the long and short fiber, after decreasing for several quarters, began to increase considerably, reaching US$205 at the end of September 2021. In Europe, pulp demand continued positively throughout the quarter, price remained unchanged at a high level, which caused the price spread with China to increase towards the end of the quarter. The tissue industry started the quarter weak, however, during the quarter it began to improve in both the At-Home and Away-from-Home segments. The P&W industry remained strong, with very good demand for their products, and producers were able to implement price increases for their final products. By the end of the quarter, some producers in the paper industry started to be affected by high energy prices, and to a lesser extent, high chemical prices. The dissolving pulp market remained steady, with prices slightly declining due to lower demand. The viscose market, after remaining stable during the first months of the quarter, began to deteriorate due to increases in some of their costs. Production during the third quarter was higher than Q2, but slightly lower compared to the same period of 2020. During the quarter we had the programmed maintenance stoppage of the Licancel mill, in Chile.

3Q 2021 RESULTS Cash Our cash position was US$1,323.5 million at the end of the third quarter, which translates to a 16.7% increase equivalent to US$189.7 million when compared to the end of the second quarter of 2021. Cash provided by operational activities increased by US$92.7 million mainly due to an increase in receipts of sales of goods, partially offset by income tax paid. Cash used in investment activities decreased US$66.4 million mainly due to a decrease in capital expenditures. Cash provided by financing activities decreased by US$138.7 mainly due to the capital injection of US$200.0 million received during the past quarter.

3Q 2021 RESULTS Third Quarter Subsequent Events and News Agreement for Selling Forestry Assets update As we informed on August, 17, 2021, with a “Material Fact” published via cmfchile.cl, the conditions precedent for the closing of the operation described on that ocassion were met and, consequently, on August 17, 2021, the parties proceeded to execute the sale of 430 properties committed in the master agreement for a price of US $ 343,668,296, plus the corresponding Value Added Tax. Additionally, on the same date, the parties entered into a supply contract and a preferential call option to purchase pulp volume of radiata pine, a fire fighting service contract and a temporary forest property management and operational task management service contract, among others. Finally, it is noted that the parties expect to carry out the sale of the 31 remaining properties to the extent that, for each of them, certain particular conditions are met within the following months, as established in the Master Agreement. The effects on our Income Statement and Adjusted EBITDA of the execution of the sale of such 430 properties are contained in the 3Q results. Studies Towards Evaluating New MDF Line in Mexico On October 29, 2021, we announced that we are beginning an Environmental Impact Assessment in México (“Estudio de Manifestación de Impacto Ambiental or “MIA” as it is known in México) as part of the assessment related to the possibility of building a new production line of MDF in Zitácuaro, a city located close to Ciudad de México (DF) (about 160 kms) where we already operate a 160kt PB mill. The project, which is subject to the approval of the competent authorities and our Board of Directors, would allow us to double our production capacity of MDF in México, thus answering to the increasing demand in the furniture and construction industries. This new MDF line -which contemplates an estimated total investment of US$200 million- would incorporate state-of-the-art operational and environmental technology. Additionally, its supply aims to foster a circular economy model, supporting small forestry producers and safekeeping the ecosystemic values of that environment. If all the necessary precedent conditions are met and we obtain the necessary permits and approvals, we believe we will start construction of the new line, and subsequently start producing during 2024. Redemption of USD Notes due 2022 On October 11, 2021, we redeemed in full the outstanding amount of our 4.75% USD-denominated notes due 2022. This prepayment was done at par value, according to provisions of the Indenture and the terms and conditions of the securities representing such notes which allowed us to redeem at par three months before the final maturity date. This implied paying the outstanding 126,168,000 USD plus the corresponding accrued interest. The rationale for this redemption is related to our strong commitment of managing our debt in accordance with our Investment Grade, and also to the positive market conditions which have allowed us to increase our liquidity.

3Q 2021 RESULTS Third Quarter Subsequent Events and News MAPA Project update MAPA Project overall progress as of the end of October 2021 was 90.0% . Construction work continues, as well as the commissioning and startup of some facilities and equipment. During the quarter, we have enacted campaigns related to a safe commissioning of the equipment within companies currently at work in the Project. We have also increased the scope of action of our “Equipo Previene” (Prevention Team) which is tasked with monitoring and supervising compliance with sanitary protocols and measures for workers of the project, both in public spaces and in local lodging facilities. We recently communicated to clients and the market that we now estimate that the startup of the MAPA Project will take place during March of 2022. This is mainly due to delays in construction. At that point the existing eucalyptus line (Line 1) will be permanently shut down in accordance with the environmental permit. ARAUCO at the COP26 – UN Climate Change Conference in Glasgow In the COP26, we announced our Climate Action Plan (“Plan de Acción Climática”) aimed at reducing our greenhouse gas emissions by 1 million tonnes by 2030. This strategy is based on three main pillars: (i) mitigation based on science, aimed at replacing fossil fuels in our productive processes, (ii) conservation and restoration of ecosystems and (iii) circular economy. This adds to our continuous efforts in these matters, such as our declaration as the first forestry company to be certified as carbon neutral, to our adherence to the “Science Based Targets” (SBTs) and also to the “Race to Zero”. Dividend Policy and Payments With respect to the Material Fact published via cmfchile.cl on September 28th, 2021, we hereby inform that both dividend payments announced on such date were paid by us to our shareholders. On October 25th, 2021, we paid our shareholders a total of US$200 million with respect to the aforementioned extraordinary dividend. After that, on November 5th, 2021, we paid our shareholders a total of US$271 million as an interim dividend with respect to the financial results of the year 2021.
