Home  Corporate Governance
AES Tietê adopts the best corporate governance practices and directs its efforts towards
increasing the Company’s sustainability, emphasizing transparency and respect in its actions and
communication with all stakeholders; environmental respect and insertion within the community;
and consistent economic growth of the Company in order to assure fair compensation
for its shareholders.

Although the Company has not adhered to any of the standards of corporate governance practice of
the São Paulo Stock Exchange (BOVESPA), 27% of the members of its Board of Directors are
independent representatives, what has become the requirement of Bovespa for companies that
participate in Level 2. This initiative is in line with the AES Group’s corporate strategy
throughout the world.

As part of a U.S. corporation with shares listed on the New York Stock Exchange, in 2005 AES Tietê
standardized internal processes and controls in order to comply with the requirements of the
Sarbanes-Oxley Act that apply to the AES Corporation.
Board of Directors
The Board of Directors is made up of 11 members, of whom seven represent the controlling
shareholder, one represents BNDES, one represents the employees and two are independent members.
Board members have a unified term of three years.
Management Committee
The Company has a permanent management committee containing six members –
three representatives of AES and three representing BNDES. It is up to the Committee to offer
technical support and advice to the Board of the Directors and Executive Management.
The Committee’s duties are:
(i) to analyze the proposal of the Annual Business Plan;
(ii) to examine proposals for capital expenditures plans for expansion, replacement and
improvements of the installations, planning and budget related to operations and maintenance;
(iii) to monitor the evolution of performance indicators;
(iv) to verify that services are being adequately provided in compliance with the
regulatory requirements; and
(v) to monitor the execution of the Annual Business Plan, as well as examining all the questions
involving strategic matter and any material technical-operational, judicial, administrative,
economic-financial, environmental and social issues considered relevant.
Fiscal Council
It is made up to five members of which three are representatives of the BNDES and two members
are appointed by minority shareholders.
External Audit
Ernst & Young Auditores Independentes has been the independent auditor of AES Tietê since 2004,
in compliance with the requirement of rotating the independent auditor every five years.
During the year, the auditors were not hired for any complementary services or consultancy
other than exclusively audit of the Company’s accounts.
Investor Relations
In order to guarantee total transparency of its relations with investors and a perfectly equitable
disclosure of information, since 2004 the Company has implemented a Policy for the Disclosure of
Relevant Information that was approved by the Board of Directors and is in compliance with the
directives of the Brazilian Securities and Exchange Commission (CVM). The Investor Relations
department interacts with investors and analysts and has the mission of moving the Company
into close relationship with the market. In order to facilitate the access of these professionals to our
information, the IR department conduct organized four conference calls during 2005 to present and
disclose its quarter results, held a number of meetings with analysts and investors during different
events and put on a public meeting at the Brazilian Association of Security Analysts (ABAMEC-RJ).
Through the work carried out by this department and due to the greater liquidity of its shares
at Bovespa, the number of financial institutions that regularly cover the Company’s stock rose
from 3 at the end of 2004 to 10 at the end of 2005.
