Gross Operating Revenue increased 12.9% to R$ 780.5 million in 2Q11 and 38.0% when
compared with 2Q10 due in large part to the increase of 122.6% in construction revenues,
of 38.0% in revenues from operations and maintenance and 3.6% from financial revenues
in the past 12 months.

Deductions from Operating Revenue increased 6.3% in the quarter and 43.9% in the past
12 months, reaching R$ 89.7 million in 2Q11 against R$ 84.6 million in 1Q11 and R$ 62.3
million in 2Q10, due to the increase verified in the last 12 months of 22.3% in regulatory
charges due principally to an increase in CCC –Fuel Consumption Account combined with
64.3% tax on revenue reflecting growth in operating revenue.

9. Costs of the Operating Services and
Operational Expenses
Major changes:
Construction together with operation and maintenance costs posted an
increase of 40.4% relative to the first quarter of 2011 and 60.7% against the
same period in 2010, totaling R$ 358.9 million in 2Q11 against R$ 255.7
million in 1Q11 and the R$ 223.3 million in 2Q10.
This variation arises largely from the increase of 174% in expenditures with
materials, reflecting the progress made in work at Serra do Japi and
IEMadeira in addition to upgrading and expansion work at CTEEP in the past
12 months.
Other operating expenses refer mainly to the loss arising from the fair
revaluation of assets when the acquisition of control of IEMG, the amount of
R$ 28.5 million and amortization of goodwill of the amount of R$ 14.4 million.
