IDC-008/2015 To BM&FBOVESPA S.A. - Bolsa de Valores, Mercadorias e Futuros Superintendence of Companies’ Follow-up At. Sr. Nelson Barroso Ortega São Paulo (SP) Ref.: Clarification on broadcasted news by newspaper Valor Econômico from July 3rd 2015 Dear Sirs, In response to your questions presented in the above Official Letter, follow the requested clarification: (i) in March 2014, Duratex announced the investment in the wood panel plant operation at Triângulo Mineiro. However, in the 4th quarter 2014 Management Report, the Company informed that this investment was under revision, due to the deterioration of the economic scenario. Since the Company has enough capacity to meet current demand, the beginning of this new plant construction will depend on the recovery of internal market growth. Even if the market resume the growth observed in the last years, there will be no necessity to increase capacity for the next 3 years; (ii) regarding our Strategic Plan, it is under revision, considering the economic scenario. The growth goals are maintained and will be adjusted to the economy’s behavior, keeping in mind that the investment described at item (i) is a relevant part of this strategy; and (iii) as reported in our 1st quarter 2015 Management Report, the Company together with Falconi Consultancy has started, in November 2014 the Duratex Management System with focus in reducing the costs with several internal actions. This action plan estimates to enable the reffered saving accumulated in 3 years, but will also depend on the economy performance in the next years. We remain available for any further clarification.
