A free translation from Portuguese into English of Independent Auditor’s Report on Individual and Consolidated Financial Statements prepared in Brazilian currency in accordance with accounting practices adopted in Brazil and International Financial Standards (IFRS), issued by International Accounting Standards - IASB.

Independent auditor’s report on individual and consolidated financial statements To the Shareholders, Board of Directors and Officers of

Duratex S.A São Paulo - SP Opinion We have audited the individual and consolidated financial statements of Duratex S.A. (“Company”), identified as Company and Consolidated, respectively, which comprise the statement of financial position as at December 31, 2017 and the related statements of profit or loss, of comprehensive income (loss), of changes in equity, and cash flows for the year then ended, and notes to the financial statements, including a summary of significant accounting practices. In our opinion, the accompanying financial statements referred to above present fairly, in all material respects, the individual and consolidated financial position of the Company as at December 31, 2017, its individual and consolidated financial performance and its individual and consolidated cash flows for the year then ended, in accordance with accounting practices adopted in Brazil and international financial reporting standards (IFRS) issued by the International Accounting Standards Board (IASB). Basis for opinion We conducted our audit in accordance with Brazilian and International Standards on Auditing. Our responsibilities, under those standards, are further described in the “Auditor’s responsibilities for the audit of individual and consolidated financial statements" section of our report. We are independent of the Company and its subsidiaries and comply with the relevant ethical principles set forth in the Code of Professional Ethics for Accountants and the professional standards issued by the Brazil’s National Association of State Boards of Accountancy (CFC) and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to support our opinion. Key audit matters Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current year. These matters were selected in the context of our audit of the overall individual and consolidated financial statement, and in forming our opinion thereon and, accordingly, we do not express a separate opinion on these matters. .

2

For each matter below, a description of how our audit has addressed the matter, including any comments on the results of our procedures, is disclosed in the context of the financial statement taken as a whole. We have fulfilled the responsibilities described in the “Auditor’s responsibilities for the audit of individual and consolidated financial statements” section, including those relating to these key audit matters. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement in the financial statements. The results of our procedures, including those performed to address the matters below, provide the basis for our audit opinion on the Company’s financial statements. Measurement of the fair value of biological assets The Company accounts for its forests, named biological assets, in Noncurrent assets, which are measured at fair value. At December 31, 2017, the fair value of these assets, recognized in the Company’s and its subsidiaries’ consolidated noncurrent assets amounted to R$1,698,855 thousand. The estimated fair value of biological assets was determined taking into consideration a number of assumptions, such as: forest growth rate, interest rates for cash flows discounts, estimated productivity and price of standing wood. This matter is disclosed in Notes 2, 3 and 15 to the individual and consolidated financial statements. This matter was considered a key audit matter due to the significance of the values of Company assets in connection with the usual uncertainties of this type of estimate and the judgment necessary which should be exercised by management when determining the assumptions of calculations of the fair value of the assets. How our audit addressed the matter: Our audit procedures included, among others, the use of subject matter experts to assist us in evaluating the assumptions and methodology used by Company, particularly those relating to the estimated forest growth rate, interest rates for cash flows discounts, estimated productivity and price of standing wood. We also evaluated the appropriateness of Company disclosures on the most sensitive key assumptions in the measurement of the fair value of the biological assets included in Notes 2, 3 and 15 to the financial statements. Based on the result of the audit procedures on the audit of the fair value of biological assets, which is consistent with the management evaluation, we considered that the criteria and assumptions used in management measurement of the fair value of biological assets, as well as the disclosures included in Notes 2, 3 and 15 are appropriate in the context of the overall financial statements.

Estimated realization of deferred taxes At December 31, 2017 the balance of deferred income and social contribution tax assets, recorded by the Company and its subsidiaries amounted to R$ 230,089 thousand (individual) and R$ 313.146 thousand (consolidated), which are disclosed in Notes 2 and 11 to the individual and consolidated financial statements, together with the information that Company management considers this estimate to involve the need of a critical accounting judgment related to the accounting recognition of these assets and their future recoverability. This item was considered a key audit matter, since the estimated recoverability of these taxes is complex and involves the use of a number of assumptions to estimate such amount and the related year in which such deferred taxes will be recovered in the ordinary course of the Company’s and its subsidiaries’ operations. These estimates rely on the studies of future profitability projection prepared by management, which includes forecasts of future market and business conditions regarding the business environment in which Company and its subsidiaries operate, which will allow recovering these deferred taxes in the coming years. How our audit addressed the matter: Our audit procedures included, among others, the review of projected future profitability prepared by management; the consistency of projected future profitability prepared by management when compared to the historical data related to prior year estimates. Furthermore, we engaged subject matter experts to assist us with the assumptions and methodology used by the Company and its subsidiaries when preparing these future profitability estimates. We also evaluated the fairness of Company disclosures of the estimated realization of deferred taxes in Notes 2 and 11 to financial statements. Based on the result of the audit procedures on the estimated recoverability of deferred taxes, which is consistent with the management evaluation, we considered that the criteria and assumptions used in management estimation of recoverability of deferred taxes, as well as the disclosures included in the Notes 2 and 11 are appropriate in the context of the overall financial statements. Recoverability of intangible assets - Goodwill In accordance with the accounting practices adopted in Brazil and international financial reporting standards, the Company is required to annually perform a test of recoverability of the amounts recorded as indefinite life intangible assets, including goodwill. At December 31, 2017 the goodwill balance was R$254,798 thousand and R$ 358,861 thousand, individual and consolidated respectively, as disclosed in Notes 2, 3, 16 and 17 to individual and consolidated financial statements. This item was considered a key audit matter, as the evaluation of the recoverability of these intangible assets is complex and involves a high degree of subjectivity, based on various assumptions such as: determination of cash generating units, discount rates, percentage of growth and profitability of the Company’s and its subsidiaries’ business for a number of future years. Such assumptions may be significantly affected by market conditions or future economic scenarios in Brazil, which cannot yet be estimated accurately.

How our audit addressed the matter: Our audit procedures included, among others, the involvement of subject matter experts to assist us with evaluating the assumptions and methodologies used by the Company and its subsidiaries, especially those relating to future sales, growth rate, rate used in discounted cash flows, and profit margin of all cash generating units. We also evaluated the fairness of Company disclosures of key assumptions which are more sensitive when testing the recoverability of intangible assets (goodwill), included in Notes 2, 3, 16 and 17 to financial statements. Based on the result of the audit procedures on the recoverability of intangible assets (goodwill), which is consistent with the management evaluation, we considered that the criteria and assumptions used in management estimation of recoverability of intangible assets (goodwill), as well as the disclosures included in the Notes 2, 3, 16 and 17 are appropriate in the context of the overall financial statements. Other matters Statements of value added The individual and consolidated statements of value added for the year ended December 31, 2017, prepared under Company management responsibility, the presentation of which is required as supplementary information under IFRS, have been subject to audit procedures in conjunction with the audit of the Company’s financial statements. In order to form our opinion, we analyzed whether these statements are reconciled to the financial statements and accounting records, as applicable, and whether their form and content meet the criteria defined in Accounting Pronouncement CPC 09 - Statements of Value Added. In our opinion, these statements of value added were fairly prepared, in all material respects, in accordance with the criteria defined in referred to Accounting Pronouncement and are consistent with the overall individual and consolidated financial statements. Other information accompanying the individual and consolidated financial statements and independent auditor’s report Company management is responsible for other information included in the Management Report. Our opinion on the individual and consolidated financial statements does not encompass the Management Report; accordingly, we do not express any form of audit conclusion thereon. In connection with the individual and consolidated financial statements, we are responsible for reading the Management Report and, in so doing, considering whether such report presents significant inconsistency with the financial statements or with our knowledge obtained in the audit, or otherwise seems to present material misstatements. If, based on the work performed, we conclude that the Management Report presents material misstatements, we are required to communicate such fact. We have nothing to report in this regard.

Responsibilities of management and of those charged with governance for the individual and consolidated financial statements Management is responsible for the preparation and fair presentation of these individual and consolidated financial statements in accordance with accounting practices adopted in Brazil and international financial reporting standards issued by the International Accounting Standards Board (IASB), and for such internal control as Management determines is necessary to enable the preparation of financial statements that are free of material misstatement, whether due to fraud or error. In preparing the individual and consolidated financial statements, management is responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company and its subsidiaries or to cease operations, or has no realistic alternative but to do so. Those charged with governance of Company and subsidiaries are responsible for overseeing the financial reporting process, which comprise the executive board of the Company and of its subsidiaries, the Audit and Risk Management Committee and the Board of Directors. Auditor’s responsibilities for the audit of individual and consolidated financial statements Our objectives are to obtain reasonable assurance about whether the individual and consolidated financial statements as a whole are free of material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Brazilian and International standards on auditing will always detect material misstatements when they exist. Misstatements can arise from fraud or error and are considered material if they could, individually or as a whole, reasonably be expected to influence the economic decisions of users made on the basis of these financial statements. As part of the audit conducted in accordance with Brazilian and International standards on auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

Identify and assess risks of material misstatements of the individual and consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than one resulting from error, as fraud may involve override of internal controls, collusion, forgery, intentional omissions or misrepresentations.

Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of internal control of the Company and its subsidiaries.

Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

Conclude on the appropriateness of management's use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast substantial doubt as to the ability of the Company and its subsidiaries to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the individual and consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company and its subsidiaries to cease to continue as a going concern.

Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the individual and consolidated financial statements represent the corresponding transactions and events in a manner that achieves fair presentation.

Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the group to express an opinion on the individual and consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provided those charged with governance with a statement that we have complied with relevant ethical requirements, including those regarding independence, and communicated with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we are required to determine those matters that were of most significance in the audit of the individual and consolidated financial statements of the current period and are therefore the key audit matters. We are required to describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

MANAGEMENT REPORT 2017 MARKET AND BUSINESS SCENARIO The fourth quarter of 2017 has brought the consolidation of economic recovery in Brazil, reflecting positively on our operations. Inflation below the target’s lower band, along with the downward path of interest rates and the return of credit and consumption have provided the necessary foundations for the recovery of activity in the Wood and Deca divisions. One of the propellers behind the return of activity in our business has been the recovery of demand, driven mainly by an increase in consumption by part of Brazilian families which, after undergoing a tough period of deleveraging, have now started to take credit once again. The Brazilian Institute for Geography and Statistics (IBGE) has registered a net increase of 9.8% in the consumption of furniture and electric appliances up to November, after two consecutive downturns in 2015 and 2016. In the wood panel segment, the Brazilian Institute of Trees (Instituto Brasileiro de Árvores - IBÁ) has registered an increase in domestic demand of 13% in the fourth quarter and 4% in the year. The demand in the foreign market has increased 21% in the year and 6% in the quarter. The demand for wood panels has grown 6% in the year when considering both internal and foreign markets. The Brazilian Institute of Construction Materials (Associação Brasileira da Indústria de Materiais de Construção - ABRAMAT), which is responsible for measuring evolution in the construction sector, points towards a fall in revenues of 4% in the year, in line with their projections, and a decrease of 5.7% in employment within the industry. The institute estimates a discreet growth of 1.5% in 2018, which is in line with our assumption of gradual recovery in demand. The Brazilian economy is expected to stabilize in 2018, and GDP to grow at 2.66%, according to the average of estimates in the FOCUS report published by the Central Bank on 01/26/2017. We remain cautiously optimistic with the recovery of our sectors of activity which have been negatively impacted by the politic and economic crises of the past few years. STRATEGIC MANAGEMENT & INVESTMENT Total investments totaled BRL 82.6 million within the last three months of the year, of which BRL 39.0 million have been directed to forest OPEX and BRL 43.6 million to factory maintenance and projects. In 2017, investments have represented BRL 365.9 million, below our original estimate of BRL 420 million. This result illustrates Duratex’s commitment to maximizing cash generation and financial deleveraging. The results of recently acquired Ceusa, a reference in the ceramic tiles industry, have been consolidated into Duratex in October, after CADE’s- Conselho Administrativo de Defesa Econômica approval. As previously disclosed, Ceusa was acquired for BRL 280.0 million (before the debt acquisition and variance in working capital) and marked the Duratex’s entrance into the ceramic tiles industry, thus complimenting the Company’s solution portfolio. We expect to integrate operations, thus further leveraging the businesses’ returns, in 2018. One of the highlights of 2017 was the consolidation of the Duratex Management System (Sistema de Gestão Duratex – SGD), encompassing all of the company’s efforts in terms of gains in efficiency, productivity, cost management and asset returns. An office with a dedicated team was created specifically for the management and dissemination of this project, besides the structuring of a methodology to measure progress. These initiatives, with the objective of offsetting the slow economic recovery, closed the year with a saving of BRL 76 million. The result reflects the Company’s commitment and discipline to a more effective cost and expenses management. The Company has reached an important landmark in its journey towards cultural transformation, where all leaderships have been capacitated and dissemination for 100% of the Company. It has been two years since we embarked on this transformation, and one can already take notice of a more rejuvenated and innovative company, ever committed to the return of its operations. In addition, we completed the assessment of Great

3

Place to Work’s, and were recognized for our good environment for employees, in their opinion. Regarding the next periods, the commitment and accountability of everyone, especially the leadership, is going to be fundamental in encouraging the development of teams in terms of performance and behavior, thus ensuring Duratex’s prominence in its sectors of activity and as an employer. We have disclosed on January 31, 2018, as a subsequent event, the disposal of installations and equipment dedicated to the production of Thin Wood Fiber Boards (hardboard) located in the city of Botucatu. The evolution of the wood panel market in Brazil, and the decision to resume activities in the Itapetininga unit, has made these lines, which are directed mainly towards exports, small within Duratex’s portfolio of solutions. This product has therefore lost relevance within the Company’s strategy. The transaction refers to the swap of installation and equipment for a production farm located in the city of Capão Bonito, in the State of São Paulo, strategically closer to our unit in Itapetininga, at the base amount of BRL 60 million. The remaining lines of Thick and Thin Wood Fiber Board (MDF and HDF) continue to be operated as usual by Duratex. As legally required, this operation is being forwarded to CADE and will be finalized as soon as approval is received. The management of these lines remain with Duratex in the regular production standards for the time being. Being the search for higher returns and greater efficiency central objective in our strategy, we have announced on February 5th, 2018, the sale of land and forests located in the the state of São Paulo to Suzano Papel e Celulose. The evolution of forest management and technology within the last six decades has allowed the Duratex to increase its productivity, and therefore, to hold a volume of land and forests that exceeds the current and projected needs of its wood panel factories. Duratex has opted for the sale of such exceeding assets. The transaction foresees the sale of land and forests in the the central region of the state of São Paulo, and is structured in two parts, being: (i) Acquisition of about 9,500 (nine thousand and five hundred) hectares of rural property and forests assets in the total value of BRL 308.1 million. (ii) Exclusive option for Suzano to purchase an additional 20,000 (twenty thousand) hectares of land and forests assets in the total amount of BRL 749.4 million, to be exercised until 07/02/2018. This operation is subject to the conditions usual to this type of transaction and to approval by the Conselho Administrativo de Defesa Econômica - CADE. The values received will be directed towards the significant reduction of net debt, thus reducing financial costs and positioning the company at a strategic level of competitiveness. These movements take place in the direction of increasing productivity, efficiency and of improving the use of our assets and reduce financing costs, and thus contribute to a higher return on operations. DIVIDENDS Duratex’s dividend policy requires a minimum dividend distribution of 30% of the adjusted net earnings. According to the proposal addressed by the Board, it was considered BRL 60.8 million as dividends, as interest on equity, equivalent to BRL 0.08826330461 per share. CONSOLIDATED FINANCIAL HIGHLIGHTS

Several initiatives were successfully implemented throughout the year, including price increases, and commercial and product development actions aimed at stimulating demand and improving the mix, along with efforts in cost reduction, as previously stated. As registered by IBÁ, the positive scenario in demand propelled the volume of wood panels marketed, which, along with the normalization of market share, lead to an expedition of 671.7 thousand m³. This quarter registered the best expedition of the year, 5.2% above 2016. We have noticed a slight deterioration of the mix in this quarter, due to the fact that most of the growth in volume was concentrated in the standard lines that have a smaller added value. This deterioration was offset by a more efficient cost dilution, a consequence of operational leveraging. The result was a fourth quarter EBITDA of BRL 157.4 million, and a margin of 22.7%, in line with the results registered in the previous quarter. Efforts related to cost reduction and gains in efficiency within the scope of the SGD will continue to be our focus in 2018. We have the opportunity to rearrange the mix of our production by exploring our logistic system and the competitive advantage of each of our five wood panel production units. We are taking measures to stimulate the demand for wood panels and the fidelity of clients, by offering high quality services while maintaining prices at levels that benefit the return of our operations.

Deca Division

(1) EBITDA (Earnings Before Interest,Taxes, Depreciation and Amortization): Measure of operational performance

according to Instruction CVM527/12. (2) Extraordinary Events: 3Q16: (i) devolution of excess from the private pension plan (-) BRL 4,443 K; (ii)Non-recurring

employee restitutions (+) BRL 7,579 K.

The civil construction materials industry registered a quarter of mild contraction, and we now begin to glimpse at a discreet growth of the sector in 2018. Despite this challenging scenario, Deca presented a growth of 2.4% in volumes in comparison to 2016. Net revenue was positively affected in the quarter by the incorporation of the results of the recently-acquired Ceusa, which recorded an expedition of 531.5 thousand m² in the quarter. When excluding this effect, Deca’s net revenue presented an increase of 8.8% in comparison to the same period of 2016. We have noticed a positive expansion in Deca’s sales this year, reflecting the strength and recognition of the brand and quality of portfolio products that are instrumental in the development of our activities in this difficult moment. We have also noticed a mild deterioration of mix of sold products, which is natural due to the seasonality of Deca’s products that show a lighter participation of finished products. This effect is mainly due to the smaller expedition of electric shower heads due to the higher temperatures this time of the year. The gross margin, however, increased from 28.2% to 27.4%, mainly a consequence of the incorporation of Ceusa into the results. Additionally, there were planned stops within Deca’s production units. These stops resulted in a negative impact of approximately BRL 10 million in the costs of the division. The investments in advertising and promotions were intensified during the last months of the year, due mainly to efforts in the positioning of the brand and more aggressive competition. In addition to this effect, there was an increase in freight costs and larger administrative expenses resulting from adjustments made throughout the second semester. With regards to Ceusa, there was the recognition of BRL 25.4 million as revenue resulting from the adhesion to the REFIS PERT program. This amount was accounted as other operational results, and had a positive impact on Deca this quarter.

As a result, Deca’s Adjusted and Recurring EBITDA was BRL 71.5 million and BRL 257.9 million in the year, respectively, with a margin of 17.5%. The annual result presented an evolution of 46% in comparison to 2016. This improvement is a reflection of all the adjustments made in this division, even in a period of crisis. Considering the slow and gradual recovery of the sector, we continue to focus on the differentiated positioning of the division, brought forth by the brands Deca, Hydra, and the recently-acquired Ceusa, along with the emphasis on relationships with clients, consumers and specifiers, allied with consistent cost-management, as the main proponents of results in 2018. CAPITAL MARKETS AND CORPORATE GOVERNANCE Duratex closed 2017 with a Market Cap of BRL 6,341.6 million, based on a closing share price of BRL 9.20. There were 459.4 thousand trades in DTEX3 at the B3 spot market within the fourth quarter. This represents a trading volume equivalent to BRL 1,639.9 million, or a daily trading volume of BRL 27.8 million. In 2017, there were 1,330.5 thousand trades in at the B3 sport market, which represented a financial volume of BRL 4,372.0 million or a daily average trading volume of BRL 17.8 million. Our shares are listed on the Novo Mercado sections of B3 which brings together companies with the highest standards of corporate governance. We also have a differentiated dividend policy, with the distribution of 30% of adjusted net earnings to shareholders, while also adhering to the Abrasca Code for Self-Regulation and Good Practices for Listed Companies. SOCIAL AND ENVIRONMENTAL RESPONSIBILITY There was an increase in our headcount once Ceusa was incorporated into Duratex. We closed 2017 with 11,400 employees. It is worth mentioning that, despite the increase in headcount, the amount dedicated to employee remuneration varied with less intensity in 2017, thus reflecting our efforts in adjusting processes and capturing cost cuts in the Duratex Management system (SGD).

The measurement of the non-controlling interest is determined for each acquisition realized. The excess of the consideration transferred and the acquisition date fair value of any previous equity interest in the acquire over the fair value of the group’s share of the identifiable net assets acquired is recorded as goodwill. If the acquisition cost is less than the fair value of the net assets of the acquired subsidiary, the difference is recognized directly in the statement of income as gain. Intercompany transactions between consolidated companies, as well as the balances and unrealized gains and losses in relation to those transactions, were eliminated. When required, the subsidiaries' accounting policies were adjusted to ensure consistency with the accounting policies of the Company. (c) Transactions and participation of non-controlling They are registered as identical manner to operations with stockholders of the Group. For acquisitions of non-controlling ownership interests, the difference between any consideration paid and the acquired portion of the parent company’s net assets are recorded in stockholders’ equity (on capital transactions with partners), as well as gains or losses on sales to non-controlling stockholders. (d) Investment in jointly controlled entity (joint operation) Duratex Florestal Ltda. subsidiary of Duratex S.A., which holds 99,99% of its capital and Usina Caeté S.A. have partnership agreement to jointly control the Caetex Florestal S.A., a joint operation created for the formation of eucalyptus forests in northeastern of Brazil. This association will mature in 39 years and each partner has a 50% share of the voting capital of Caetex Florestal S.A. 2.2.2 – New accounting standards, amendments and interpretations They were issued by the International Accounting Standards Board (IASB) but were not effective until on December 31, 2017 for early adoption in Brasil. The Company and its subsidiaries not adopted these changes in the preparation of these financial statements. The Group is obligate to adopt CPC 48/ IFRS 9 Financial Instruments and CPC 47/ IFRS 15 Revenues from contracts with customers beginning from January 1st, 2018. The Group have already valuated the estimated impact that the initial application from CPC 48/ IFRS 9 (a) and CPC 47/ IFRS 15 (b) will have in its consolidated financial statements. The estimated impact of adoption of these standards on equity from the Group on January 1st, 2018 is based in valuations realized until the issue date of these financial statements. The new accounting policies are subject


19

to changes until the Group presents its first financial statements that include the initial application date. Estimated impact of adoption of CPC 48/ IFRS 9 and CPC 47/ IFRS 15 The total estimated adjust (net of tax) in the initial balance from stockholders’ equity of the Group on January 1st, 2018 is R$ 4,215. The mainly components of the estimated adjust are as follows: (a) A reduction in retained earnings of R$ 1,654 (net of taxes), due to losses by decrease to the

recoverable value of trade accounts receivable. (b) A reduction in retained earnings of R$ 2,561 (net of taxes), due to recognition of deductions

from sales by bonus given to the customers by achievement of volumes from purchase of products.

(a) CPC 48/ IFRS 9 Financial Instruments In July 2014, the IASB issued the final version of IFRS 9 - Financial Instruments, which replaces IAS 39 – Financial Instruments: Recognition and Measurement and all early versions of IFRS 9. The IFRS 9 gather three aspects of the project of accounting financial instruments: classification and measurement, reduction to the recoverable value of asset and accounting of hedge. The IFRS 9 is in force for annual periods beginning from January 1st, 2018, being allowed its early application. Except in the accounting of hedge, it is necessary the retrospective application; however, the supply of comparatives information is not compulsory. The Group will adopt the new standard in the effective date required and do not submit again the comparatives information. In 2017, the Group realizes a detailed valuation of impact of the three aspects of IFRS 9. In general, the Group doesn’t predict any significate impact in the balance sheet and statement of changes in stockholders’ equity, except by the effect from application of the requirements of reduction of recoverable value of IFRS 9. The Group expects an increase of provision for losses, resulting in a negative impact on stockholders’ equity, in according to described below: (a1) Classification and measurement The Group does not expect significant impacts in its balance sheet or stockholders’ equity in the application of classification and measurement requirements of IFRS 9. Loans, as well as, trade accounts receivable are maintained for capture contractual cash flow and should generate cash flow representing just payments of principal and interests. The Group analyses the contractual characteristics of cash flow from these instruments and conclude that they meet the criteria of amortized cost measurement in accordance to IFRS 9. Therefore, do not necessary the reclassification for these instruments. (a2) Reduction to the recoverable value The IFRS 9 require that the Group record the expected credit losses in all its debt titles, loans and trade accounts receivable. The Group will apply the simplified approach and will record expected losses during all life in trade accounts receivable. The Group determines that due to the nature not guaranteed from its receivables, the provision for losses will increase in R$ 2,506, with correspondent reduction of the deferred fiscal liability in the amount of R$ 852.


20

(a3) Accounting of hedge Once IFRS 9 does not change the general principles as the entity record effectives hedges, the requirements application of hedge from IFRS 9 won’t have significates impacts in the financial statements from the Group. In resume, expects that the impact of adoption of IFRS 9 be the follow:

Asset

Accounts receivable from customers (2,506)

Deferred income tax and social contribution 852

Stockholders' equity

Retained earnings (1,654) (b) CPC 47/ IFRS 15 Revenue from contracts with clients The IFRS 15 was issued in May 2014, changed in April 2016 and establishes a model of five steps for accounting of revenues from contracts with clients. In accordance to IFRS 15, the revenue is recognized by a value that reflects the counterpart that an entity expects to have rights in return of transfer of goods or services for a client. The new standard will replaces all current requirements of recognition of revenue in accordance to IFRS. The complete retrospective application or the modified retrospective application will be required for annual periods beginning from January 1st, 2018. The Group will apply the new standard in the current date required based on the complete retrospective method. Sale of goods For contracts with clients that in generally expects that the sale of products be the only obligation of execution, the adoption of IFRS 15 shouldn’t have impact and in the revenue and in the result from the Group. The Group expects that the revenue recognition occurs in the moment that the control of goods is transferred for the client, generally by delivery of goods. The reduction in retained earnings of R$ 2,561 (net of taxes) due to recognition of deduction from sales by bonus given to the clients by achievement of estimative of volumes from purchase of products. In resume, expects that the impact of adoption of IFRS 15 be the follow:

Asset

Deferred income tax and social contribution 1,319

Liability

Accounts payable 3,880

Stockholders' equity

Retained earnings (2,561) IFRS 16 - Leases, which replaces IAS 17, unifying the accounting treatment of operating and finance leases for the model similar to financial leasing with impact on fixed asset and financial liability. This standard will effective in January 1st, 2019 and the Company is evaluating the content and the possible impacts of the adoption of this pronouncement.


21

There are no other standards and interpretations issued and not yet adopted that, in Management's opinion, have a significant impact on the results or stockholders’ equity disclosed by the Company. 2.3 – Presentation of segmented information Segmented information is presented consistently with the main operating decision maker. The main operating decision maker, responsible for allocating funds and evaluating the performance of operating segments, is the Company's Board of Directors, which is in charge of the Group's strategic decision making, with the support of the Supervisory Board. 2.4 – Foreign currency translation (a) Functional currency and presentation currency The items included in the financial statements of each of the companies are measured using the main currency of the economic environment in which the respective company operates (“the functional currency”). The individual and consolidated financial statements are presented in Brazilian Reais, which is the Company’s functional and also presentation currency of financial statements.

(b) Transactions and balances Transactions in foreign currencies are converted into the functional currency using the exchange rates prevailing on the transaction or evaluation dates in the event that the items are remeasured. Exchange gains and losses arising from the settlement of those transactions and from the conversion at period-end exchange rates of monetary assets and liabilities in foreign currencies are recognized in the statement of income as financial income or expenses, except when they are recorded directly in stockholders' equity and considered to be a hedge of net investments. (c) Companies of the group with different functional currencies The net income and financial position of the subsidiaries located abroad (none of which operate in hyperinflationary economy), whose functional currency is different from the presentation currency (Brazilian Reais), are converted into the presentation currency as follow:

assets and liabilities are translated at the exchange rate on the balance sheet date;

income and expenses are translated at the average exchange rate for the month in which they are recorded;

all resulting exchange-related differences are recognized in stockholders' equity as “accumulated conversion adjustments” and are recognized in the net income when the investments are realized;

goodwill and fair value adjustments resulting from the acquisition of a foreign entity are recognized as assets and liabilities of the foreign entity and translated at the closing exchange rate. 2.5 – Cash and cash equivalents Cash and cash equivalents include cash, bank deposits and other short-term highly liquid investments with original maturities of three months or less, and subject to an insignificant risk of changes in value.


22

2.6 – Financial assets 2.6.1 – Classification The classification of financial assets is determined by Management when they are initially recognized, and depends on the purpose for which they were acquired. The financial assets are classified into two categories: (a) Financial assets measured at fair value through profit or loss A financial asset is classified in this category if it was acquired, mainly, for short-term sale purposes and it is booked as current assets. Derivatives are also categorized as held for trading, unless they have been designated as hedging instruments. (b) Loans and receivables Loans and receivables are non-derivative financial assets with fixed or determinable payments which are not quoted in an active market. They are included in current assets, except for those maturing at least 12 months after the balance sheet issue date, which are classified as non-current assets. Loans and receivables represent accounts receivable from clients, other accounts receivable and cash and cash equivalents, except for short-term investments. 2.6.2 – Recognition and measurement Purchases and sales of financial assets are recognized on the trading date, which is the date when the Company and its subsidiaries commit to buy or sell the asset. Loans and receivables are recorded at amortized cost using the effective interest rate method. Financial assets classified at fair value through profit or loss is initially recognized at their fair value, and transaction costs are charged to the statement of income. Financial assets are written off when the rights to receive cash flow from the investments have been realized or transferred, and, in the latter case, as long as the Company and its subsidiaries have transferred significantly all of the risks and benefits of ownership. Financial assets measured at fair value through profit or loss is subsequently recorded at fair value. Gains or losses resulting from fluctuations in the fair values of financial assets measured at fair value through profit or loss are presented in the statement of income in the year in which they occur. The fair values of publicly quoted assets and liabilities are based on their current purchase prices. If the market of a financial asset (for securities not listed in a stock exchange) is not active, the Company establishes fair value by using valuation techniques. These techniques include the use of transactions with third parties, reference to other substantially similar instruments, analysis of discounted cash flow models and option pricing models making the maximum use of information generated by the market and the least possible use of information generated by the Management of the Company.


23

2.6.3 – Offsetting of financial instruments Financial assets and liabilities can be reported at their net amounts in the balance sheet only when there is a legal right to offset the amounts recognized and there is intent to settle them on a net basis, or to realize the asset and settle the liability simultaneously. 2.6.4 – Impairment of financial assets At the end of each reporting year, the Company and its subsidiaries evaluates whether there is objective evidence that a financial asset or group of financial assets has been impaired. An asset or group of financial assets is deemed to be impaired, and impairment losses are incurred, only if there is objective evidence of impairment as a result of one or more events occurring after the initial recognition of the assets (a “loss event”) and that event (or events) of impairment have an impact on the estimated future cash flow from the financial asset or group of financial assets which can be reliably estimated. The criteria used by the Company and its subsidiaries to determine whether there is objective evidence of an impairment loss include:

relevant financial difficult of the issuer or debtor;

a breach of contract, such as a default or delay in the payment of interest or principal;

the disappearance of an active market for that financial asset due to financial difficulties, or

observable data indicating a measurable reduction in the estimated future cash flow from a financial asset portfolio since the initial recognition of those assets, even if the decrease cannot yet be allocated to the individual financial assets in the portfolio, including:

a) adverse changes in the payment situation of the portfolio's borrowers; b) national or local economic conditions correlating with adverse changes in the payment

situation of the portfolio's borrowers; c) national or local economic conditions correlating with defaults on the portfolio's assets. The Company and its subsidiaries first evaluate whether there is objective evidence of impairment. The loss amount by impairment is measured as the difference between the book value of the assets and the present value of estimated future cash flow (excluding future credit losses not yet incurred) discounted based on the original interest rates of the financial assets. The book value of the assets is reduced and the amount of the loss is recognized in the statement of income. If a loan or investment maintained until maturity date has a variable interest rate, the discount rate utilized to measure the impairment loss is the current effective interest rate determined in accordance with the contract. For practical purposes, the Company and its subsidiaries can measure the impairment based on the fair value of the instrument, utilizing an observable market price. If, in a subsequent period, the value of the impairment loss decreases and the decrease can be objectively related to an event that has occurred after the impairment has been recognized, (such as an improvement in the debtor's credit classification), the reversal of the previously recognized impairment loss is recognized in the statement of income. 2.7 – Derivative financial instruments and hedging activities Derivatives are initially recognized at fair value on the date when the derivative agreement is entered into, and are subsequently, remeasured at fair value through the results. Derivatives are contracted as a form of financial risk management, and the Company’s policy is not to enter into leveraged derivative transactions.


24

Although the Company does not have a hedge accounting policy, it has designated certain debts at fair value through profit or loss, because of the existence of derivative financial assets directly related to loans, as a means of avoiding the recognition of gains and losses in different periods. 2.8 – Trade accounts receivable Trade accounts receivable are recorded and maintained at the nominal value of the titles obtained from sales of products, plus exchange variations, when applicable. Trade accounts receivable mainly relate to short-term operations, and are therefore not discounted to their present value, because no represents significant adjustments on the financial statements. The estimated loss with impairment in the accounts receivable is made based on the analysis of the risk of realization of the credit receivables, at an amount considered sufficient by Management to cover potential losses on the realization of these assets. 2.9 – Inventory Inventory is stated at the average purchase or production cost, not exceeding the replacement cost or realizable amount, between two, the lower. Imports in transit are stated at the cost of each import. The cost of finished goods and work in progress comprises the cost of raw materials, direct labor, other direct costs and related direct production costs (based on normal capacity). The net realizable value is the estimated selling price in the normal course of business, less the estimated costs of conclusion and the estimated costs necessary to make the sale. 2.10 – Intangible assets The account group that comprise the intangible assets are as follows: Goodwill Goodwill is represented by the positive difference between the amount paid and or payable for the acquisition of a business and the net fair value of the assets and liabilities of the acquired subsidiary in a business combination. Goodwill is not amortized in the accounting and only will be written off by sale or by impairment, through annual test to identify whether there is any need to record of losses. This goodwill is realized (amortized) for tax purposes, having base the current law, being that the corresponding income tax and social contribution is constituted. Goodwill is allocated to Cash Generating Units (UGCs) for impairment. The allocation is made for the Cash Generating Unit or for the group of Cash Generating Units that should to benefit from the business combination on which the goodwill arose. Trademarks and patents Separately acquired trademarks and licenses are initially stated at historical cost. Trademarks and licenses acquired during a business combination are recognized at their fair value on the acquisition date. Contractual relationships with customers – customer portfolio Customer relationships acquired just in a business combination are recognized at fair value on the acquisition date. Customer relationships have finite useful lives and therefore are amortized. Amortization is calculated using the straight line method over the expected useful life of the customer relationship.


25

Softwares Acquired software licenses are recorded as capital expenditure at the amount of the costs incurred to acquire the software and prepare it for use. The cost is amortized over the estimated useful life of the software. 2.11 – Property, plant and equipment Items of property, plant and equipment are stated at their cost of acquisition, formation or construction, including financing costs related to the acquisition of assets that require some time to get done, net of accumulated depreciation calculated by straight line method, and taking into consideration the estimated economically useful lives of the respective assets and, which are reviewed at the end of each year. Subsequent costs are included in a book value of asset, or are recognized as a separate asset, as applicable, only when it is likely that the future economic benefits associated to the item and that the cost can be measured with security. The book values of replaced items and parts are written off. All other repair and maintenance costs are recorded against results for the year in the period of occurrence. The value of property, plant and equipment is reduced to its recoverable amount if the book value exceeds the estimated recoverable amount. Gains and losses on disposals are determined by comparing the results with the book value and are recognized in "other operating income (losses), net". 2.12 – Impairment of non-financial assets Assets which have an indeterminate useful life, such as Goodwill, are not subject to amortization and are tested annually for impairment. The assets subject to depreciation or amortization are tested whenever there is objective evidence (events or changes of circumstances) that the book value may not be recoverable. For this purpose, the companies take into consideration the effects arising from obsolescence, demand, competition and other economic factors. For impairment testing purposes, assets are grouped at the lowest level for which there is separately identifiable cash flow (Cash Generating Unit - UGCs). 2.13 – Biological assets Forest reserves are recognized at their fair value, less the estimated selling costs at harvest time, as described in Note 15. For immature plantations (up to one year old), the cost is considered to approximate at the fair value. Gains or losses arise from the recognition of biological assets at their fair value, less selling costs, are recognized in the statement of income. The depletion appropriated to the results is made by the formation costs portion and the fair value adjustments portion. The effect of the variation in the fair value of a biological asset is presented in a separate account in the statement of income. 2.14 – Loans and financing Borrowing is initially recognized at its fair value when funds are received, net of transaction costs, and subsequently stated at amortized cost, in other words, with the addition of charges and interest proportional interests to the incurred period (calculated on a pro rata basis), using the effective interest rate method, except for those which has derivative instruments of protection, which will be valuated at fair value.


26

Borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset, i.e. an asset that requires a substantial period of time to be done for its use or sale, are capitalized as part of the cost of the asset when it is probable that will result in future economic benefits to the entity which can be reliably measured. Other borrowing costs are recognized as expenses in the year in which they are incurred. 2.15 – Accounts payable to suppliers and provisions Suppliers Accounts payable to suppliers are obligations to pay for goods or services that were purchased in the ordinary course of business, and are classified as current liabilities if payment is due in the period as at one year. Otherwise, the accounts payable are presented as non-current liabilities. Accounts payable are initially recognized at their nominal value, which is equivalent to the fair value, and, subsequently, measured at amortized cost using the effective interest rate method. Provisions Provisions are recognized when there is a present legal or no formalized as result from past events, and which being probable the necessity of disbursement of funds will be required to settle the obligation, and the amount can be reliably estimated. Provisions are not recognized to the future operating losses. Provisions are measured at the present value of the expenses that should be necessary to settle the obligation, and reflecting the risks specific to the obligation. 2.16 – Current and deferred income tax and social contributions The income tax and social contributions are calculated based on the net income for the year before constitution of income tax and social contribution, adjusted by inclusions and exclusions in accordance to current tax legislation. Deferred income tax and social contributions are recognized on temporary differences between the tax basis of assets and liabilities and their book values in the financial statements. In practice, on accounting profit inclusions of expenses and exclusion of revenue, both are temporary no taxable, generate records of credit or debit of deferred tax. These taxes are recognized in the statement of income, except for the proportion related to items directly recognized in stockholders’ equity. In this case, the tax is also recorded in stockholders’ equity. Current income tax and social contributions are presented in liabilities on a net basis when there are amounts payable or in assets when the amount paid in advance exceeds the total owed at the reporting date. Assets and liabilities deferred taxes are presented net, if exists the legal right or contractual to offset the fiscal asset against fiscal liability, and the deferred tax are related to the same taxable entity and subject to the same taxable authority. Deferred taxes and contributions are recognized only if their offsetting against future taxable income is probable. 2.17 – Employee benefits (a) Pension and health plans The Company and some of its subsidiaries offer to all of their employees a defined contribution plan managed by Fundação Itaúsa Industrial. The regulations of the plan establish that the


27

sponsoring companies will make a contribution ranging from 50% to 100% of the amount contributed by the employees. The Company previously offered a defined benefit plan to its employees, but this plan is being phased out, with enrollment not permitted for new participants. In relation to the defined contribution plan, the Company and its subsidiaries have no further additional of payment obligations after the contributions are made. The contributions are recognized as employee benefit expenses when they are due. Contributions made in advance are recognized as an asset to the extent that these contributions lead to an effective reduction in future payments. The Company offers both contributory plans, currently with co-participation, as contributories plans (Tubarão – SC unit) to its employees and their dependents, through 13 health care providers, totaling 29,394 lives (actives, dismissed, retired and dependents) characterizing the obligation of extension to coverage for dismissed and retired persons according to Law 9,656/98. (b) Share-based compensation The Company offers to its executives a compensation plan based on stock options, according to which it receives their services from executives as consideration for the stock options granted. The fair value of stock options granted, is recognized as an expense, with a corresponding entry to stockholders’ equity during the year in which the executives render the services and acquire the right to exercise the stock options. The fair value of the options granted is calculated at the grant date of the options, and at each balance sheet, the Company revises its estimates of the quantity of shares it expects to issue, based on the vesting conditions. (c) Profit sharing The Company and its subsidiaries compensate their employees through profit sharing if established performance targets are met in the year. This remuneration is recognized as a liability and an expense in the operating results when the employee fulfils the established performance conditions. 2.18 – Capital The common shares are classified in stockholders’ equity. Incremental costs directly attributable to the issue of new shares or options are presented in stockholders’ equity as a deduction from the funds obtained, net of taxes. The amount paid for the acquisition of treasury shares, including any directly additional attributable costs, is deducted from the equity attributable to the stockholders until the shares are cancelled, sold or utilized in the stock option plan. 2.19 – Revenue recognition Revenue represents the fair value of the consideration received or receivable for the sale of products in the normal course of the activities of the Company and its subsidiaries. Revenue is stated net of taxes, returns, discounts or rebates granted, as well as the elimination of intercompany sales, and is recognized when its amount can be reliably measured, and when it is probable that future economic benefits will be obtained by the Company and specific criteria, detailed below, for each of the relevant activities have been met.


28

(a) Sales of goods Sales revenue is recognized on the delivery of the products, as well as by the transfer of the risks and benefits to the buyer. (b) Financial income Financial income is recognized in accordance with the elapsed period, using the effective interest rate method. When a loss (impairment) is identified on a financial instrument, the Company and its subsidiaries reduce the book value to its recoverable value, which corresponds to the estimated future cash flow, discounted at the original effective contractual interest rate of the instrument. 2.20 - Variation in the fair value of biological assets They are recognized by the valuation of the expected volumes at harvest point, by the current market prices based on the volume estimates. 2.21 – Leases The Company has lease contracts on land utilized for forestry activities. In these contracts, the risks and rights of ownership are retained by the lessor, and the leases are therefore classified as operating leases. The costs incurred in operating lease agreements are recorded as part of the cost of formation of biological assets, using the straight line method, over the contractual period. 2.22 – Distribution of dividends and interests on capital The distribution of dividends or interests on capital to Company stockholders is recognized as a liability in the financial statements at the end of each year, or on interim dates, as determined by the Supervisory Board. The balance is calculated based on the minimum dividend established in the Company's bylaws, net of the amounts approved and paid during the year. Note 3 – Critical accounting judgments and estimates During the preparation of the financial statements, accounting judgments, estimates and assumptions are utilized to record the amounts of certain assets, liabilities and other transactions. The definition of estimates and accounting judgments adopted by Management were based on the information available on the date, involving experience of past events and forecasts of future events. The financial statements includes several estimates, as: the useful lives of property plant and equipment, realization of deferred tax credits, impairment in the trade accounts receivable, inventory losses, the evaluation of the fair value of biological assets, and provision for contingencies, impairment testing of goodwill, pension plan and health benefits and others. The main estimates and assumptions that entail a substantial risk with probability to causes adjustments in the book values of assets and liabilities are presented below: a) Risk of variations in the fair value of biological assets The Group used several estimates to evaluate its forestry reserves in accordance with the methodology established by CPC 29/IAS 41 – “Biological asset and agriculture product”. These estimates were based on market references, and are subject to scenarios changes which could impact the financial statements. Specifically, a 5% reduction in standing wood market prices would result in a reduction in the fair value of biological assets in order to R$ 55.7 million, net of tax effects. If the discount rate used were increased by 0.5%, this would result in a reduction in the fair value of biological assets of about R$ 11.6 million, net of tax effects.


29

b) Estimated impairment of goodwill The Company and its subsidiaries test the goodwill on annual basis or if there is an indication any time possible impairment of goodwill in accordance with accounting policy presented in the notes 2.10 and 2.12. The balance can be impacted by changes in the economic and market scenario. c) Pension plan and health benefits The current value of assets/ liabilities related to pension plans and health depends on a number of factors that are determined using actuarial calculations. These calculations involve a series of assumptions, including the discount rate and current market conditions. Any changes in these assumptions will affect the corresponding book values. d) Provision for contingencies The Group constitute provision for tax, labor, civil and social security contingencies, based on valuation of probability of loss that are made by legal advisors from the Company, the amounts are updated and believe that the constituted provisions as at closing date are sufficient for cover eventual losses with lawsuits and administrative in progress. e) Fair value of financial instruments When the fair value from financial assets and liabilities presented in the balance sheet cannot be obtained of market assets, are determined utilizing valuation techniques, including cash flow discounted method. The data for these methods is based in those practiced in the market, when it possible, however, when this does not viable, a determined level of judgement is required for establishes the fair value. The judgment includes considerations on used data, for example, risk of liquidity, risk of credit and volatility. Changes in the assumptions on these factors could affect the fair value presented of the financial statements. Note 4 – Financial risk management 4.1 Financial risk factors The Company and its subsidiaries are exposed to market risk in relation to fluctuations of interest, exchange rates and credit. So, the risk manage follows the policies approved by Board of Directors, including monitoring by Audit and Management of Risk Committee. The Company and its subsidiaries have procedures to manage these situations and can use hedging instruments to reduce the impact of the risks. These procedures include monitoring the level of exposure to each market risk, in addition to establish limits for the respective decision-making. All hedging transactions entered into by the Group are intended to protect its debts and investments. The Group does not utilize any leveraged financial derivatives. Market risk (I) Exchange rate risk: Exchange rate risk corresponds to a reduction in the value of the Group's assets or an increase in its liabilities due to changes in exchange rates. The Company and its subsidiaries have indebtedness policy that establishes the maximum amount in foreign currency to which it is exposed to exchange rate variations.


30

In line with the risk management procedures, the objective is to minimize the foreign exchange exposure of the Company and its subsidiaries, hedging mechanisms are maintained, in order to mitigate, in large part, the foreign exchange exposure. (II) Derivatives: In terms of derivative instruments, there are no verifications, monthly settlements or margin calls are made, and the contracts are settled upon maturity and recorded at fair value, considering the market conditions for terms and interest rates. The outstanding contracts as at December 31, 2017 were as follow: a) US$ vs. Interbank deposit certificate (CDI) swap agreements The Company has four agreements of this nature, whose aggregate notional amount is US$ 181,300,000, and varying maturities up to August 16, 2019, with an asset (purchase) position in US Dollars and a liability (sale) position in CDI. The Company made these agreements in order to change its debts denominated in US Dollars into debts indexed to the CDI. b) Fixed rate vs. Interbank deposit certificate (CDI) swap agreements The Company has two agreements with an aggregate amount of R$ 20,000, maturing through January 12, 2018, consisting of an asset position at a fixed rate and a liability position at a percentage of the CDI. The Company contracted these operations with the purpose of change the debits with fixed interests rates in debts indexed to CDI. c) Non Deliverable Forward (NDF) agreement

The Company has one agreement of this nature, whose contracted amount totalizes US$ 31,000,000 maturing through January 31, 2018 and position sold in US Dollars.

The Company contracted these agreements in order to reset the foreign exchange exposure on the contracted date (December 27, 2017). In this transaction the contracted is settled at their respective maturity, considering the difference between the exchange rate to term (NDF) and exchange rate in the end of the period (Ptax). d) Calculation of the fair value of positions The fair value of the financial instruments was calculated utilizing the estimated present value of both liability and asset positions, where the difference between the two represents the market value of the Swap.

(a) Credit Risk The Company policy of sales are directly associated to the level of credit risk that are willing to accept in the course of its business. The diversification of its portfolio of receivables, selection of its customers, as well as monitoring of the sales financing terms and individual limits are procedures adopted in order to minimize defaults or losses on the realization of accounts receivable. In relation to temporary cash investments and all other investments, the Group follows the policy of working only with blue-chip institutions and not concentrating its investments on any one economic group. (b) Liquidity risk The Company and its subsidiaries have a indebtedness policy which defines the limits and parameters for debt, and the minimum funds which should be maintained, the latter being the higher of the following values: an amount equivalent to 60 days of consolidated net revenue of the last quarter or the amount of the debt servicing expenses plus dividends and/or interest on capital forecast for the following six months. The control of liquidity position occurs daily through of cash flow monitoring.

4.3 Fair value estimates It is assumed that the book values of trade account receivable and accounts payable to suppliers, less the provision for loss (impairment), are close to their fair values. The fair value of the financial liabilities for disclosure purposes is estimated by discounting of the future contractual cash flow by current market interest rate which is available for the Company and its subsidiaries for similar financial instruments. The Company and its subsidiaries apply CPC 40-R1/ IFRS 7 “Financial instruments: disclosures” for financial instruments measured on balance sheet at fair value, which requires the disclosure of the measurement criteria used. As the Company has only Level 2 derivatives, it uses the following valuation techniques: • The fair value of the interest rate “swap” is calculated based on the present value of the estimated future cash flow based on the yield curves adopted by the market; • The fair values foreign currency forward contracts are determined based on future exchange rates at the balance sheet dates, with the resulting amounts discounted to their present values. The consolidated financial instruments (by category/level) are presented below:

Note 15 – Biological assets (forest reserves) Through its subsidiaries Duratex Florestal Ltda. and Duratex S.A. (new name of Tablemac S.A.), as well as, its jointly controlled, Caetex Florestal S.A., eucalyptus and pine forest reserves, which are primarily utilized as raw materials for producing wood panels, floors and complementarily for sale to third parties. The reserves guarantee supplies to the factories, and also protect the Company against the risk of future wood price increases. Operating in a sustainable way and integrated with the manufacturing facilities, these reserves, together with a supply network, provide the Company with a high degree of self-sufficiency in terms of wood supplies. As at December 31, 2017 the Group had roughly 179,600 hectares, of planted areas (December 31, 2016: 176,700 hectares) that are cultivated in the States of São Paulo, Minas Gerais, Rio Grande do Sul, Alagoas and in Colombia. a) Fair value estimate The fair value is calculated based on an estimate of the volume of wood ready for harvesting, at the current prices for standing wood, exception for: the Eucalyptus forests until one year old, and Pinus until 4 years old, which are stated at cost, because the values approximates to the fair value. Biological assets are measured at fair value, less selling costs at the time of harvesting. Fair value is determined by valuing the estimated ready-to-harvest volumes at current market prices, based on volume estimates. The assumptions utilized were: i. Discounted cash flow – the estimated volume of ready-to-harvest wood, considering current market prices, net of costs to be incurred and the capital costs of the lands (brought to their present value) by the discount rate of 5.7% p.a. as at December 31, 2017. The discount rate used in cash flow corresponds to the weighted average cost of the Company, which is reviewed annually by the Management. ii. Prices – the cubic meter prices in R$ are obtained from market price surveys disclosed by specialized firms in regions and similar products to the Group, in addition to prices obtained from third party transactions, also in active markets. iii. Differentiation - the volumes harvested were categorized and valued according to: specie, (a) pinus and eucalyptus, (b) region, (c) destination: sawmill and processing. iv. Volume – the estimated volumes to be harvested (in the sixth year for eucalyptus and in the twelfth year for pine) based on the projected average productivity for each region and specie. Average productivity may vary based on age, rotation, climatic conditions, quality of seedlings,


45

fires, and other natural risks. For mature forests are utilized the current volumes of wood. The estimates of volume are corroborate for rotating physical inventory realized for technical specialists from the second year of a forest's life, and its effects incorporated into the financial statements. v. Regularity - expectations regarding to future wood prices and volumes are reviewed at least every quarter, or when the rotational physical inventory is concluded. b) Composition of balance The biological assets balance is made up of the cost of forest formation and adjustments to fair value, as shown below:

12/31/2017 12/31/2016

Formation cost of biological assets 1,044,450 966,180

The average price on December 31, 2017 was R$ 43.24/ m³ (on December 31, 2016 was R$ 43.32/ m³). Price increases lead to an increase in the fair value of forests. At each 5% of variation in price, the impact on the fair value of forests would be in order of R$ 84,342. In relation to the discount rate, was used 5.7% p.a. on December 31, 2017. Increases in the rate lead to a drop in the fair value of the forest. Each 0.5% p.a. the variation in the rate would affect the fair value in approximately R$ 17,643.

The period explicit of projection used was 10 years, because of in the 5 years early of projection the unit does not reach the full operation level of its current capacity prejudicing the calculation of perpetuity. The adoption of this period, in according to the Management opinion, allows a better representation of results and cash flow of the company in the long term and reflects the specific characteristics of the business. The cash flow was discounted for the rate of 10.35% p.a. on December 31, 2017 (12.32% p.a. in 2016) and the perpetuity was calculated using the last year of explicit period and considering a growth rate of 2.0% p.a..

Main variables used in the calculation of value in use For the calculation of value in use of cash generating units of Panels, Ceramic, Metals and showers follow variables were used:

Gross margin

Discount rates

Growth rates used in perpetuity Gross Margins The gross margins were projected considering a recovery of prices and volumes align with historical results and in gains forecasted with dilution of fixed costs due to reduction of idleness in the factories. This growth represents an average percent of 1.2% p.a. in panels, 0.8% p.a. for ceramics, 0.5% p.a. for metals and 0.6% p.a. for showers.


49

Discount rate The discount rate represents the evaluation of current risks of the Company and was calculated by the Weighted Average Cost of Capital (WACC) methodology that considers the financing debits components and own capital used by the Company to finance its activities. The cost of own capital of Duratex was calculated by the method CAPM (Capital Asset Pricing Model) that considers the specific risk of the business through beta. This calculation is revised annually. An increase in the perception of specific risk (beta), market risk, country risk or of financing cost could result in an increase of discount rate. A rate increase of 1.3 p.p. could reduce the value in use by cash flow for the limit level to the fair value in analyzed UGCs. Growth rate used in perpetually The growth rate used to calculate perpetually in the cash flow after the explicit period was 2.0% p.a.. The Company believes that this percent is suitable to the average growth of the sector, as well as to be a projected inflation target by several central banks in abroad.
