#### 28 SEGMENT INFORMATION
28.1 Criteria for identifying operating segments

The Board of Directors and Board of Statutory Executive Officers evaluate the performance of the Company’s business segments through the Adjusted EBITDA. The Company has revised the segment note to present Adjusted EBITDA as its performance measure.

The operating segments defined by the Company’s management are set forth below:

i) Pulp: comprised of the production and sale of hardwood eucalyptus pulp and fluff pulp, mainly to supply the foreign market.

ii) Paper: comprises the production and sale of paper to meet the demands of both the domestic and foreign markets. Consumer goods (tissue) sales are classified under this segment due to their immateriality.

Information related to total assets by reportable segment is not disclosed, as it is not included in the set of information made available to the Company’s management, which makes investment decisions and determines the allocation of resources on a consolidated basis.

In addition, with respect to geographical information related to non-current assets, the Company does not disclose such information, as all property, plant and equipment, biological and intangible assets are substantially in Brazil.
