Earnings Release 4Q16 1. Main Events in the Period Copel’s EBITDA came to R$254.3 million in 4Q16, 78.4% lower than the R$1,175.6 million recorded in 4Q15 when R$410.6 million in non-recurring events that positively impacted the result of that period. This performance in 4Q16 was negatively impacted by (a) for the recording of R$603.7 million in provisions, mainly due to the recognition of loss of generation assets, (b) increase of 23,6% from the electricity purchase, the result of the lower Generation Scaling Factor (GSF), and (c) the fall of 2.0% in the grid market of Copel Distribuição. In 4Q16, Copel recorded a negative result of R$109.8 million compared to net income of R$402.1 million, in 4Q15. More details in the item 2. Impairment of assets of the generation segment The Company reviewed the recoverable value of its assets through the application of impairment tests. For this purpose, the value in use (discounted cash flow) criterion was used, which resulted in the recording of R$567.1 million in provisions for losses. The assets that most accounted for impairment were: the Cutia Wind Farm Complex, HPP Baixo Iguaçu, UTE Araucária and TPP Figueira. Among the assumptions used for the tests, the most relevant to the result are the discount rate update, the increase in the CAPEX of the projects and the scenario of low probability of dispatch to UTE Araucária in 2017. More details in the item 4.1. Compagas’ results After reviewing scenarios and the prospect of gas consumption for the next few years, the Compagas made an adjustment of R$89.6 million refers to the impairment of the Ship-or-Pay credit to be offset related to the gas purchase agreement entered into with Petrobras.
