Investments increased 10% to R$225 million. - Financial results declined due to a 5% decrease in revenues from tariff adjustments, and higher energy costs. EBITDA decreased 83% to R$108 million and net income declined 96% to R$14 million. - The company restructured debts, increasing average maturity to 7.2 years and reducing average costs. Covenants were also made more flexible considering regulatory assets/liabilities and IFRS changes.

.
(economic effect: +4.45%), with average combined effect of -3.25%

2

3. MP 579: Context
 AES Eletropaulo is not covered by MP 579 rules and has a concession valid until 2028
Goal
Opportunities
 Aims to reduce tariffs by 20% (Residential: 16.2% and industrial from 20% to 28%), as from February
2013, through:
- Decreasing sector charges (RGR, CCC e CDE): - 7%
- Renewal of Generation and Transmission Concessions: - 13%
 Marginal benefits in collection and potential decrease in delinquency, since energy costs will be reduced
 Increase in energy consumption, as a potential result of the drop in tariffs
Exchange rate variation of the price of energy purchased from Itaipu will no longer be suportted by
distribution companies, but by Eletrobras
Risks
 Financial impact between tariff adjustments of hydrological risks due to the allocation of energy quotas

4. Tariff review: discussions with Aneel
Discussion
Arguments
 Shielded RAB was approved by Aneel in 2003

Shielded RAB
Aneel excluded R$ 728 million from
shielded RAB, due to the decrease in
the amount of cables between the
accounting records and the shielded
RAB, between cycles
and was confirmed in 2007, considering a global
consistency criteria
 If the exclusion of the amount of cables is
maintained, an addition of R$ 660 million of
assets in operation (2003 BRR) should be
considered

Investments

Losses
Aneel did not recognize a R$ 427 million
investment performed in the incremental
period on Minor Components to Main
Equipments (“COM”) and Additional
Costs (“CA”)
Aneel changed the benchmark company
proposed in the Public Hearing,
modifying the regulatory losses from
0.49% to 1%
 Adequacy of the regulatory standards applied by
Aneel for the valuation of real costs incurred in
execution of works and recorded in accounting
books
 Benchmark company is an outlier
 Regulatory losses shall be restored to the
previous number of 0.49%

and growth potential are merely forecasts based on the

performance as well as the electric sector and international
market, and they are therefore subject to changes.
