Breakdown of Costs and Expenses - Consolidated
 Material: Decline of 33.4%, due to the reduction in
the use and optimization of costs of materials for
maintenance and repair.

insourcing of some activities and a reduction in
services rendered due to renewal of agreements.

was contingency expenses mainly due to:

R$ 13.1 million in 2Q15, CTEEP being co-
defendant in actions against delinquent
and/or insolvent companies providing
outsourced labor to the Company;

Equity Income - Consolidated
 Madeira: reduction of R$4.9 MM in 2Q15 relative to
2Q14, due to (i) increase in financial expenses from
a debenture issue; and (ii) the impact from the
adoption of the RTT in 2015 with the revision of the
SUDAM benefit through an Income Tax reduction.
 Garanhuns: growth of R$2.0 MM in 2T15
compared to 2Q14 due to the increase in the
financial assets forecasted for the realization of
amounts required for construction and indemnity.
 IENNE: the negative result in 2Q14 reflects
principally the impact of the first periodical tariff
revision under Ratifying Resolution 1.540 of June
2013, which reduced the subsidiary’s RAP by 8.9%
for the 2013/2014 cycle.
