PRESENTATION OF FINANCIAL INFORMATION 

In this annual report, references to “real,” “reais” or “R$” are to the Brazilian real, the official currency of Brazil.  
All references to “U.S. dollars” or “US$” are to United States dollars.  Solely for the convenience of the reader, we 
have  translated  some  of  the  real  amounts  contained  in  this  annual  report  into  U.S.  dollars  at  a  rate  equal  (unless 
otherwise indicated) to R$2.1380 to US$1.00, the commercial selling rate as of December 31, 2006 as reported by 
the  Central  Bank  of  Brazil,  or  the  Central  Bank.    As  a  result  of  the  recent  fluctuations  in  the  real/U.S.  dollar 
exchange rate, the commercial selling rate may not be indicative of current or future exchange rates.  Therefore, you 
should not read these translations as representations that any such amounts have been, could have been or could be 
converted  into  U.S.  dollars  at  that  or  at  any  other  exchange  rate.    See  “Item 3.A.    Selected  Financial  Data—
Exchange Rates” for information regarding exchange rates allocable to the Brazilian currency since January 1, 2002. 

Our audited  financial  statements  as of  December 31, 2005 and 2006 and  for the years  ended December 31,  2004, 
2005 and 2006 are included in this annual report.  The financial statements as of and for the years ended December 
31,  2004,  2005  and  2006  have  been  audited  by  Deloitte  Touche  Tohmatsu  Auditores  Independentes,  São  Paulo, 
Brazil.  The selected financial data as of December 31, 2002 and 2003 and for the two years ended December 31, 
2003 is derived from our financial statements audited by PricewaterhouseCoopers Auditores Independentes for the 
year  ended  December  31,  2002  and  by  Deloitte  Touche  Tohmatsu  Auditores  Independentes  for  the  year  ended 
December 31, 2003, both included in previously filed annual reports.  

Our audited financial statements are presented in reais and are prepared in accordance with the Brazilian Corporate 
Law Method, which is based on Brazilian Corporate Law (Law No. 6,404/76, as amended), the rules and regulations 
issued  by  the  Brazilian  Securities  Commission  (Comissão  de  Valores  Mobiliários),  or  CVM,  and  the  accounting 
standards  issued  by  the  Brazilian  Institute  of  Independent  Auditors  (Instituto  dos  Auditores  Independentes  do 
Brasil), or IBRACON, hereinafter referred to as the “Brazilian Corporate Law Method.” 

Like other Brazilian companies, we have the option of presenting our primary financial statements on the basis of 
accounting principles established in accordance with the Brazilian Corporate Law Method with a reconciliation to 
generally  accepted  accounting  principles  in  the  United  States  of  America,  or  U.S.  GAAP.    Unless  otherwise 
indicated,  our  financial  statements  and  all  financial  data  included  in  this  annual  report  have  been  prepared  in 
accordance with the Brazilian Corporate Law Method. 

The  Brazilian  Corporate  Law  Method  differs  in  significant  respects  from  U.S.  GAAP.    Note  23  to  our  financial 
statements provides a description of the differences between the Brazilian Corporate Law Method and U.S. GAAP 
as  they  relate  to  our  financial  statements  and  a  reconciliation  from  the  Brazilian  Corporate  Law  Method  to  U.S. 
GAAP, for periods presented therein, of our net income (loss) and shareholders’ equity.  The reconciliation from the 
financial  statements  prepared  in  accordance  with  the  Brazilian  Corporate  Law  Method  to  U.S.  GAAP  includes, 
among  others,  adjustments  for  differences  related  to  the  accounting  for  past  revaluations  of  property,  plant  and 
equipment, historical inflation accounting and accounting for pension and other employee benefits. 

All  information  related  to  liters,  water  and  sewage  volumes,  number  of  employees,  kilometers,  water  and  sewage 
connections, population served, operating productivity, water production rate, sewage lines (in kilometers), savings 
achieved and investments in improvement programs have not been audited. 

Other Information 

We do not have any subsidiaries. 

Some figures in this annual report may not total due to rounding adjustments. 

In  this  annual  report,  unless  the  context  otherwise  requires,  references  to  “we,”  “us,”  “our,”  “Company,”  or 
“Sabesp”  refer  to  Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo—Sabesp.    “Brazil”  refers  to  the 
Federative Republic of Brazil and “State” refers to the State of São Paulo, which is also our controlling shareholder.  

 
 
 
 
 
The phrases “Federal  Government” and  “Brazilian government” refer  to  the  federal government  of the  Federative 
Republic of Brazil and “State government” refers to the state government of the State of São Paulo. 

In this annual report, we refer to the “São Paulo Metropolitan Region,” the area where the Metropolitan Executive 
Office operates, comprising 38 municipalities, including the City of São Paulo.  We refer to the “Regional Systems,” 
the  area  where  the Regional  Systems Executive Ofiice operates, comprising 329  municipalities  in the interior and 
coastline  regions  of  the  State  of  São  Paulo.    As  of  the  date  of  this  annual  report,  we  provide  water  supply  and 
sewage services to a total of 367 of the 645 municipalities in the State of São Paulo. 

References  to  “Water  Coverage  Ratio”  in  this  annual  report  mean  the  ratio  between  the  number  of  residences 
connected to the water supply network, divided by the number of urban residences in a certain area.  References to 
“Sewage  Coverage  Ratio”  mean  the  ratio  between  the  number  of  residences  connected  to  the  sewage  collection 
network, divided by the number of urban residences in a certain area. 

References  to  urban  and  total  population  in  this  annual  report  are  estimated  based  on  a  research  made  by  State 
System Foundation Data Analysis (Fundação Sistema Estadual de Análise de Dados – SEADE): “Projections for the 
State of São Paulo – Population and Residences until 2025” (“Projeções para o Estado de São Paulo – População e 
Domicílios até 2025”).

Includes financial expenses, net. 

(1) 
(2)  The extraordinary item charged to income in the years ended December 31, 2004, 2005 and 2006 relates to the amortization (over a five-
year period) of the actuarial liability recorded on December 31, 2001 upon first time recognition of the defined benefits pension plan.  The 
presentation of the charge as an extraordinary item is consistent with the instructions of the CVM and the Brazilian Corporate Law Method.  
For purposes of U.S. GAAP, the pension expense has been treated as a payroll expense from the first year presented. 

(3)  Short and long-term receivables from shareholders, net represent amounts due from the State for water and sewage services.  See note 6 to 

our financial statements.  

(4)  Based  upon  the  statements  of  cash  flows  for  the  years  ended  December 31,  2006,  2005  and  2004  included  in  note  25  to  our  financial 

statements and the statements of cash flows for the years ended December 31, 2003 and 2002 which are not included in this annual report. 

(5)  The  inclusion  of  Adjusted  EBITDA  information  aims  at  presenting  a  measure  for  our  economic  operating  performance.    Our  Adjusted 
EBITDA means net income before financial expenses, net, income tax and social contribution tax (federal taxes on income), depreciation 
and amortization, non-operating income (expenses) and extraordinary item, net of income tax and social contribution.  Adjusted EBITDA is 
not a measure of financial performance recognized under the Brazilian Corporate Law Method, and should not be considered individually or 
as an alternative for net income, as a measure of operating performance, or alternative for operating cash flows, or as a measure of liquidity.  
Our  definition  of  Adjusted  EBITDA  or  EBITDA  may  not  be  comparable  with  the  definition  of  Adjusted  EBITDA  or  EBITDA  used  by 
other companies.  In our operations, we relate our Adjusted EBITDA to our operating cash flows.  We do not include in the calculation of 
Adjusted  EBITDA  expenses  with  interest,  taxes,  depreciation  and  amortization,  therefore,  our  Adjusted  EBITDA  works  as  a  general 
indicator  of  economic  performance  and  it  is  not  affected  by  debt  restructurings,  interest  rate  fluctuations,  changes  in  tax  burden  or  in 
depreciation and amortization levels.  Consequently, we believe that Adjusted EBITDA works as an adequate tool to regularly compare our 
operating performance.  Additionally, Adjusted EBITDA is used in covenants related to some of our financial commitments.  We believe 
that Adjusted EBITDA allows a better understanding not only of our financial performance but also of our capacity to satisfy our liabilities 
and to raise funds for our capital expenditures and working capital.  Adjusted EBITDA, however, has limitations that prevent it from being 
used as a  measure of our profitability because it does  not take into consideration other costs resulting  from our business or certain other 
costs, which could significantly affect our profits, such as financial expenses, taxes, depreciation, capital expenses and other related charges.  
Adjusted EBITDA calculation presented herein is in accordance with the rules issued by the Brazilian regulatory authorities, which set forth 
the Brazilian Corporate Law Method.  The table below sets forth, for the periods indicated, the reconciliation between our net income with 
Adjusted EBITDA:

Includes  both  physical  and  non-physical  losses.    Water  loss  percentage  represents  the  quotient  of  (a) the  difference  between  (i) the  total 
amount of water produced by us less (ii) the total amount of water invoiced by us to customers minus (iii) the volume of water set out below 
that we exclude from our calculation of water losses, divided by (b) the total amount of water produced.  We exclude from our calculation 
of water losses the following:  (1) water discharged for periodic maintenance of water mains and water storage tanks; (2) water supplied for 
municipal uses such as firefighting; (3) water we consume in our facilities; and (4) estimated water losses associated with water we supply 
to favelas (shantytowns).

Exchange Rates 

Before  March  14,  2005,  there  were  two  principal  legal  foreign  exchange  markets  in  Brazil,  the  commercial  rate 
exchange  market  and  the  floating  rate  exchange  market.    On  March  4,  2005,  the  Brazilian  National  Monetary 
Council (Conselho Monetário Nacional) enacted Resolution No. 3,265, pursuant to which the floating rate market 
and  the  commercial  market  were  unified  under  the  denomination  “exchange  market,”  effective  as  of  March  14, 
2005.  The new regulation allows the purchase and sale of foreign currency and the international transfer of reais by 
any person or legal entity, regardless of the amount, provided, however, the transaction is legal and subject to certain 
regulatory procedures. 

Since  1999,  the  Central  Bank  has  allowed  the  real/U.S.  dollar  exchange  rate  to  float  freely,  and,  since  then,  the 
real/U.S.  dollar  exchange  rate  has  fluctuated  considerably.    Since  the  beginning  of  2001,  the  Brazilian  exchange 
market has been increasingly volatile, and, until early 2003, the value of the real declined relative to the U.S. dollar.  
The real appreciated against the U.S. dollar in 2003, 2004, 2005 and 2006.  As of December 31, 2006, the exchange 
rate for U.S. dollars was R$2.138 per U$1.00.  In the past, the Central Bank has intervened occasionally to control 
unstable  movements  in  foreign  exchange  rates.    We  cannot  predict  whether  the  Central  Bank  or  the  Brazilian 
government will continue to let the real float freely or will intervene in the exchange rate market through the return 
of a currency band system or otherwise.  The real may depreciate or appreciate against the U.S. dollar substantially 
in the future.  For more information on these risks, see “Item 3.D. Risk Factors—Risks Relating to Brazil.” 

The  following  tables  set  forth  the  commercial  selling  rate,  expressed  in  reais  per  U.S.  dollar  (R$/US$),  for  the 
periods indicated.

3.D. Risk Factors 

Risks Relating to Brazil 

The  Brazilian  government  has  exercised,  and  continues  to  exercise,  significant  influence  over  the  Brazilian 
economy.  This involvement, as well as Brazilian political and economic conditions, could adversely affect us and 
the market price of our shares and ADSs. 

The  Brazilian  government  frequently  intervenes  in  the  Brazilian  economy  and  occasionally  makes  significant 
changes  in  policy and regulations.   The  Brazilian government’s  actions to control  inflation and other  policies and 
regulations have often involved, among other measures, increases in interest rates, changes in tax policies, price and 
tariff controls, currency devaluations, capital controls and limits on imports.  Our business, financial condition and 
results of operations, as well as the market price of our shares or ADSs, may be adversely affected by changes in 
public policy at federal, state and  municipal levels with respect to public tariffs and exchange controls, as well as 
other factors, such as: 

• 

• 

• 

• 

• 

• 

• 

• 

the regulatory environment related to our business operations and concession contracts; 

interest rates; 

exchange controls and restrictions, such as those which were briefly imposed in 1989 and 1990; 

currency fluctuations; 

inflation; 

liquidity of the Brazilian capital and lending markets; 

tax and regulatory policies; and 

other political, social and economical developments in or affecting Brazil. 

Uncertainty over whether the Brazilian government will implement changes in policy or regulation affecting these 
or other factors in the future may contribute to economic uncertainty in Brazil and to heightened volatility in the 
Brazilian securities  markets and in the securities issued abroad by Brazilian issuers, which could have  a  material 
adverse effect on us and on our shares and ADSs. 

In October 2006, Brazil held presidential elections and President Luiz Inácio Lula da Silva was reelected.  There can 
be no assurance that the Brazilian government will continue to follow the economic policies that were adopted under 
President  Luiz  Inácio  Lula  da  Silva’s  first  administration,  or  that  any  changes  that  may  be  implemented  to  these 
policies will not have an adverse effect upon us. 

Inflation, and the Brazilian government’s measures to combat inflation, may contribute to economic uncertainty 
in Brazil, adversely affecting us and the market value of our shares or ADSs. 

Brazil  has  in  the  past  experienced  extremely  high  rates  of  inflation.    Inflation  and  the  Brazilian  government’s 
measures to fight inflation have had significant negative effects on the Brazilian economy, contributing to economic 
uncertainty and heightened volatility in the  Brazilian securities  markets.   The Brazilian government’s measures to 

9 

 
 
control inflation have often included maintaining a tight monetary policy with high interest rates, thereby restricting 
the availability of credit and reducing economic growth.  The official interest rate in Brazil, the SELIC, which is the 
interest rate of the Special Clearing and Settlement System (Sistema Especial de Liquidação e Custódia), at the end 
of 2002, 2003, 2004, 2005 and 2006 was 24.90%, 16.32%, 17.74%, 18.00% and 13.19%, respectively.  On June 30, 
2007, the official interest rate in Brazil was 12.00%. 

The annual rate of inflation, as measured by the General Market Price Index (Índice Geral de Preços—Mercado), or 
IGP-M index, has fallen from 9.95% in 2000 to 3.83% in 2006.  However, Brazilian governmental actions, including 
interest rate decreases, intervention in the foreign exchange market and actions to adjust or fix the value of the real, 
may trigger increases in inflation.  If Brazil again experiences high inflation, our costs and expenses may rise, we 
may be unable to increase our tariffs to counter the effects of inflation, and our overall financial performance may be 
adversely  affected.    In  addition,  a  substantial  increase  in  inflation  may  weaken  investor’s  confidence  in  Brazil, 
causing the decline in the market value of our shares or ADSs. 

Additionally, in the event of an increase in inflation, the Brazilian government may choose to raise official interest 
rates.  Increases in interest rates would not only affect our cost of funding, but could also have a material adverse 
effect on us and may also adversely affect the market value of our shares or ADSs. 

Exchange rate instability may adversely affect us and the market price of our shares or ADSs. 

The Brazilian currency has experienced frequent and substantial devaluations in relation to the U.S. dollar and other 
foreign  currencies  during  the  last  decades.    Throughout  this  period,  the  Brazilian  government  has  implemented 
various  economic  plans  and  utilized  a  number  of  exchange  rate  policies,  including  sudden  devaluations,  periodic 
mini-devaluations during which the frequency of adjustments has ranged from daily to monthly, floating exchange 
rate  systems,  exchange  controls  and  dual  exchange  rate  markets.    From  time  to  time,  there  have  been  significant 
fluctuations in the exchange rate between the Brazilian real and the U.S. dollar and other currencies.  For example, 
the real depreciated against the U.S. dollar by 9.3% in 2000, 18.7% in 2001 and 34.3% in 2002.  Although the real 
appreciated 22.3%, 8.8%, 13.4% and 9.5% against the U.S. dollar in 2003, 2004, 2005 and 2006, respectively, no 
assurance  can  be  given  that  the  real  will  not  depreciate  against  the  U.S.  dollar  again.    On  June  30,  2007,  the 
exchange rate was R$1.9262 per US$1.00. 

In the event of a significant devaluation of the real in relation to the U.S. dollar or other currencies, our ability to 
meet  our  foreign  currency-denominated  obligations  could  be  adversely  affected,  particularly  because  our  tariff 
revenue  and  other  sources  of  income  are  based  solely  in  reais.    In  addition,  because  we  have  foreign  currency-
denominated  indebtedness,  any  significant  devaluation  of  the  real  during  a  financial  period  will  increase  our 
financial  expenses  as  a  result  of  foreign  exchange  losses  that  we  must  record.    We  had  total  foreign  currency-
denominated  indebtedness  of  R$1,472.8  million  as  of  December  31,  2006,  and  we  anticipate  that  we  may  incur 
substantial amounts of foreign currency-denominated indebtedness in the future.  Our overall results of operations 
were  positively  affected  by  the  9.5%  appreciation  of  the  real  against  the  U.S.  dollar  in  2006,  which  amounted  to 
R$96,1 million.  We do not currently have any hedging instruments in place to protect us against a devaluation of 
the real in relation to any foreign currency.  A devaluation of the real may adversely affect us and the market price 
of our shares or ADSs.  

Developments and the perception of risk in other countries, especially emerging market countries, may adversely 
affect our financing and the market price of our shares or ADSs. 

The market value of securities of Brazilian issuers is affected to varying degrees by economic and market conditions 
in other countries, including other Latin American and emerging market countries.  Although economic conditions 
in those countries may differ significantly from economic conditions in Brazil, investors’ reactions to developments 
in these other countries may have an adverse effect on the market value of securities of Brazilian issuers.  Crises in 
other emerging countries may diminish investors’ interest in securities of Brazilian issuers, including our securities.  
This could adversely affect the market price of our shares or ADSs and could also make it more difficult for us to 
gain access to the capital markets and finance our operations in the future on acceptable terms, or at all. 

10 

 
 
Risks Relating to our Control by the State of São Paulo 

We are controlled by the State of São Paulo, whose interests may differ from ours or from minority shareholders’ 
interests, and which could have a material adverse effect on us. 

The  State  of  São  Paulo,  through  its  ownership  of  our  common  shares,  has  the  ability  to  determine  our  operating 
policies  and  strategy,  to  authorize  tariff  adjustments,  to  control  the  election  of  a  majority  of  the  members  of  our 
board of directors and to appoint our senior management.  As of December 31, 2006, the State owned 50.3% of our 
outstanding common shares. 

The State has from time to time in the past, and may in the future, through its control of our board of directors, set 
our  tariffs  and  direct  that  we  engage  in  certain  business  activities  and  make  certain  expenditures  that  promote 
political, economic or social goals but that do not necessarily also enhance our business and results of operations.  
See “Item 5.A. Operating and Financial Review and Prospects—Factors Affecting Our Results of Operations.” 

Newly  elected  Governors  of  the  State  typically  make  significant  changes  in  our  board  of  directors  and  senior 
management and, historically, the chairman of our board of directors has been the Secretary of the former Energy, 
Water  Resources  and  Sanitation  Secretariat  of  the  State  (Secretaria  Estadual  de  Energia,  Recursos  Hídricos  e 
Saneamento),  currently  denominated  Sanitation  and  Energy  Secretariat  of  the  State  of  São  Paulo  (Secretaria  de 
Saneamento e Energia do Estado de São Paulo). 

We  have  a  substantial  amount  of  accounts  receivable  owed  to  us  by  the  State  and  some  State  entities,  and  we 
cannot assure you as to when or whether the State will pay us. 

Historically, the State and some State entities have had substantial overdue accounts payable to us relating to (1) the 
provision  of  water  and  sewage  services  and  (2)  State-mandated  special  retirement  and  pension  payments  that  we 
make to some of our former employees for which the State is required to reimburse us.  As of December 31, 2006, 
the  amounts  owed to us by the State  for the provision of  water and  sewage  services totaled R$456.9  million and, 
with respect to payment of pensions on behalf of the State, the State owed us R$774.5 million.  Amounts owed to us 
by the State for water and sewage services and reimbursements for pensions paid may increase in the future.  

We  have  entered  into  agreements  with  the  State  to  settle  these  overdue  amounts  payable  to  us.    For  a  detailed 
discussion of these agreements, see “Item 7.B.  Major Shareholders and Related Party Transactions—Related Party 
Transactions.”  Pursuant to these agreements, the amounts due with respect to  water and sewage services  may be 
settled  through  the  application  of  dividends  payable  to  the  State  by  us  to  the  repayment  of  amounts  owed  to  us.  
Since  the  State  entered  into  these  agreements  in  1997,  we  have  applied  the  dividends  payable  to  the  State  to  the 
repayment of amounts owed to us.  However, the agreements do not require application of all dividends payable to 
the State to the repayment of amounts owed to us.  Furthermore, there can be no assurance as to whether and to what 
extent we will continue to record sufficient profits to pay dividends.   

Pursuant to the agreements, part of the amounts due to us with respect to payments of pensions on behalf of the State 
may be settled through the transfer to us of certain reservoirs in the Alto Tietê system that we use and are owned by 
the  State.    We  are  unable  to  predict  whether  and  when  these  reservoirs  will  be  transferred  to  us  because  a  final 
judicial determination as to the fair value of these reservoirs is still pending and the Public Prosecution Office of the 
State of São Paulo (Ministério Público do Estado de São Paulo) brought a civil public action alleging that a transfer 
to us of ownership of the Alto Tietê system reservoirs is illegal.  See “Item 8.A. Consolidated Statements and other 
Financial Information—Legal Proceedings.” 

We cannot assure you as to when or if the State will pay overdue amounts owed to us.  Due to the State’s history of 
not  making  timely  payments  to  us  in  respect  of  services  and  of  not  reimbursing  us  in  a  timely  manner  for  the 
payments of pensions on behalf of the State, we cannot assure you that the amount of accounts receivable owed to us 
by the State and some State entities will not significantly increase in the future.  In addition, we have not established 
any provisions for any amounts due to us by the State, as we do not expect to incur any significant losses relating to 
these amounts.  If the State does not pay the amount it owes to us, we will be adversely affected. 

11 

 
 
We may be required to acquire reservoirs that we use and that are owned by a State-controlled company, or we 
may be required to pay substantial charges to the owner with respect to our use of these reservoirs. 

In connection with the provision of water services, we use the Billings and Guarapiranga reservoirs that are owned 
by a State-controlled company.  Our right to use these reservoirs is provided for through a grant issued by the State 
Department  of  Water  and  Energy  (Departamento  de  Águas  e  Energia  Elétrica  do  Estado  de  São  Paulo—DAEE).  
The State, through its control of our board of directors, could require us to acquire the Billings and  Guarapiranga 
reservoirs.    As  a  result  of  these  acquisitions,  our  cash  position  and  overall  financial  condition  could  be  adversely 
affected.    In  addition,  since  we  are  not  currently  charged  for  the  use  of  these  reservoirs,  we  are  uncertain  as  to 
whether we will continue to be able to use the reservoirs without paying charges, or what the likely fee scale would 
be,  if  imposed.    We  may  also  be  required  to  pay  additional  maintenance  and  operational  costs  for  our  use  of  the 
Billings  and  Guarapiranga  reservoirs.    If  we  were  required  to  pay  substantial  charges  to  the  owner  or  additional 
maintenance or operational costs for our use of these properties, we could be adversely affected. 

Risks Relating to Our Business 

We  cannot  anticipate  the  effects  that  the  new  legislation  enacted  in  January  2007  will  have  on  the  basic 
sanitation sector in Brazil. 

On January 8, 2007, Law No. 11,445 was enacted to regulate the basic sanitation industry in Brazil.  This law is in 
its  initial  stage  of  implementation  and  we  cannot  anticipate  the  effects  that  it  will  have  on  our  operations  and 
business.  There are several uncertainties related to the new legislation, mainly with respect to the imposition of the 
regulatory authority for the basic sanitation industry and the tariff adjustment formula and structure that will be used 
for new contracts that we will enter into under the new law, which could have a material adverse effect on us.  See 
“Item 4.B. Business Overview—The Basic Sanitation Law.” 

We are exposed to risks associated with the provision of water and sewage services. 

We engage in the provision of water and sewage services, which are essential public services.  In addition to being 
subject to the discretionary power of the State and the Federal Government and several governmental regulations, 
our industry is specifically affected by the following risks:  

• 

• 

• 

• 

we  may  become  subject  to  substantial  water-related  and  sewage-related  charges  imposed  by 
governmental water agencies of the State and of the Federal Government related to the abstraction 
of water from, or dumping of sewage into, water resources controlled by these agencies, which we 
may  not  be  able  to  pass  on  to  our  customers.    See  “Item  4.B.  Business  Overview—Government 
Regulation —Water Usage”; 

in some cases, we are required to continue providing services to certain municipalities to which we 
provide water on a wholesale basis that have overdue amounts owed to us and are not paying us 
on a regular basis and we cannot assure you as to when or whether these municipalities will pay 
us; 

we may be unable to increase our tariffs in line with increases in inflation and operating expenses, 
including taxes, or to increase them in a timely manner, due to political and legal constraints that 
may  hinder  us  from  passing  on  to  our  customers  increases  in  our  cost  structure.    Also,  we  are 
highly  dependent  upon  our  ability  to  timely  set  and  collect  adequate  tariffs  for  our  water  and 
sewage services to fund our capital expenditure program and financing activities and to meet our 
debt service requirements.  For a detailed discussion of the effect of tariff increases, see “Item 5.A. 
Operating  and Financial  Review  and Prospects—Factors  Affecting Our  Results of  Operations—
Effects of Tariff Increases”; 

we  are  exposed  to  droughts  that  may  adversely  affect  our  water  supply  systems,  resulting  in  a 
decrease in the volume of water distributed and billed as well as in the revenue from water supply; 
and 

12 

 
 
• 

we are dependent upon energy to conduct our operations and shortages or rationing of energy may 
prevent us from providing water and sewage services and may also cause material damages to our 
water and sewage systems when we resume operations.  Also, we may not be able to pass on to 
customers significant increases in energy tariffs.  

The occurrence of any of the above may have a material adverse effect on us. 

We  do  not  hold  formal  concessions  to  provide  water  and  sewage  services  to  the  City  of  São  Paulo  and  several 
other municipalities that we serve, and therefore we may not be able to enforce our rights to continue to provide 
services in these municipalities. 

Our operations are concentrated in the City of São Paulo with which we have not entered into a concession contract. 
As  of  December  31,  2006,  the  City  of  São  Paulo  accounted  for  56.8%  of  our  sales  and  services  rendered.    In 
addition, we do not hold formal concessions in 40 other municipalities in the State of São Paulo, particularly in the 
municipality of Santos, in the coastal region, where we operate under a deed of authorization (escritura pública de 
autorização) and that has a significant population of aproximately 426,000 as of December 31, 2006. 

Because we do not hold concessions or formal contract rights to provide services in these municipalities, we may not 
be able to effectively enforce our right to continue to provide services or to be paid for the services we provide.  In 
the  future,  our  rights  in  respect  of  the  City  of  São  Paulo  and  these  other  municipalities  could  be  modified  or 
adversely affected by Brazilian federal, state or local governmental actions, judicial decisions or other factors.  

From time to time, mayors of the City of São Paulo have initiated or proposed discussions with the State regarding 
entering into a formal concession contract with us to provide water and sewage services in the City of São Paulo.  
For  a  detailed  discussion  of  these  initiatives,  see  “Item  4.B.  Business  Overview—Government  Regulation—
Concessions.” 

The new basic sanitation legislation, Law No. 11,445, enacted in January 2007, provides December 31, 2010 as the 
deadline  for  water  and  sewage  services  companies,  such  as  us,  to  regularize  the  provision  of  water  and  sewage 
services to municipalities, in case there is no formal concessions to provide services to municipalities.  We cannot 
anticipate  the  terms  and  conditions  of  these  contracts  and  their  effects  on  the  provision  of  our  services  in  these 
municipalities, particularly with respect to the City of São Paulo. 

Furthermore, we cannot assure you when and if there will be changes to the conditions under which we currently 
provide  water  and  sewage  services  to  these  municipalities  without  holding  formal  concessions  and  we  cannot 
anticipate their effects on the provision of our services in the City of São Paulo and in these other municipalities. 

We may face difficulties to continue to provide water and sewage services in the municipalities we serve and we 
cannot  assure  you  that  these  municipalities  will  continue  to  require  our  provision  of  services  under  the  same 
terms. 

We  provide  water  and  sewage  services  to  367  municipalities  in  the  State  of  São  Paulo,  of  which  324  we  operate 
pursuant  to  concessions  granted  by  the  municipalities.    Substantially  all  of  these  concessions  have  30-year  terms.  
Until  December  31,  2006,  120  of  our  concessions  had  expired,  all  of  which  are  under  negotiation.    In  2007,  53 
concessions will expire.  From 2008 through 2034, 150 concessions will expire.  The remainder of the concessions is 
for an undetermined period of time.  As of December 31, 2006, the book value of our assets in the municipalities 
where  the  concessions  are  under  negotiation  or  will  expire  in  2007  totaled  R$1.9  billion.    For  the  year  ended 
December 31, 2006, the net revenue from sales and services was R$796.0 million with respect to these concessions. 

In case certain municipalities continue to require our provision of water and sewage services, we cannot assure you 
that we will obtain in the new contracts the same terms under which we currently provide services to them because 
the  new  basic  sanitation  law  prevents  us  from  planning,  regulating  and  monitoring  our  services  and  it  requires  a 
more  stringent  control  by  the  municipalities  or  by  the  regulatory  entity  to  be  created  for  the  Brazilian  basic 
sanitation industry.  In case certain municipalities no longer require our provision of water and sewage services, we 

13 

 
 
may adversely affected.  See “Item 4.B. Business Overview—Our Operations” and “Item 4.B. Business Overview—
Government Regulation—Public Consortia Law.”   

We may also face difficulties in continuing to provide water and sewage services to certain municipalities by means 
of new contracts because of an increase in competition and in case we are outbid from a public bidding process.   

Municipalities may terminate our concessions before their expiration and the compensation may be inadequate to 
recover the full value of our investments. 

The  concessions  we  hold  are  subject  to  early  termination  by  the  municipalities  under  certain  circumstances.  
Municipalities  may  terminate  our  concessions  if  we  fail  to  comply  with  our  obligations  under  the  relevant 
concession contract and applicable law, or if the municipality determines, based on authorization by municipal law, 
through an expropriation proceeding, that terminating our concession prior to the contractual expiration date is in the 
public interest.  If any municipality terminates our concession, we are entitled to be indemnified for the unamortized 
portion  of  our  investments,  but  the  compensation  may  not  be  sufficient  for  us  to  recover  the  full  value  of  our 
investments.    Further,  under  the  terms  of  the  Constitution  of  the  State  of  São  Paulo,  we  may  receive  the 
compensation over a term of 25 years.  The early termination by municipalities of any of our concession contracts, 
or our inability to receive adequate compensation for the investments we  made, or if compensation is paid over a 
term of 25 years, would have a material adverse effect on us. 

In 1997, the municipality of Santos enacted a law expropriating our water and sewage systems in Santos.  In 1995, 
the  municipality  of  Diadema  terminated  the  concession  agreement  that  had  been  entered  into  with  us  prior  to  the 
expiration of the agreement.  There are pending legal proceedings discussing both the expropriation carried out by 
the municipality of Santos and early termination by the municipality of Diadema.  We continue to provide water and 
sewage  services  to  Santos  and  sell  water  on  a  wholesale  basis  to  Diadema.    For  further  information  on  these 
lawsuits, see “See “Item 8.A. Consolidated Statements and other Financial Information—Legal Proceedings.” 

We cannot assure you  that other  municipalities  will not  seek  to  terminate  their  concessions before the  contractual 
expiration  date.    Exercise  of  concession  termination  rights  by  substantial  numbers  of  municipalities  could  have  a 
material adverse effect on us. 

Law No. 11,445, the new basic sanitation law, provides that the parties to new contracts have to establish the amount 
of  the  compensation  in  the  agreement  for  the  unamortized  portion  of  the  invesment  in  case  of  termination  of  the 
agreement prior  to  the contractual  expiration date.  In the  event there  is  no  agreement between  the parties  for the 
unamortized portion of the invesment to  be repaid to the service provider in case of termination of the agreement 
prior  to  the  contractual  expiration  date,  the  new  law  determines  a  default  provision,  i.e.,  the  valuation  of  the 
investment by an independent expert based on the economic value or revaluation of the book value of the invesment.  
This default provision of Law No. 11,445 may also be applicable to current concessions but in the absence of mutual 
agreements,  the  calculation  of  the  indemnity  is  based  on  the  terms  and  conditions  of  the  previous  agreement.    In 
addition,  we  cannot  anticipate  the  effects  of  this  law  on  the  amount  of,  and  enforceability  of  the  right  to, 
compensation and how Brazilian courts will enforce the provisions of Law No. 11,445. 

Any failure to obtain new financing may adversely affect our ability to continue our capital expenditure program. 

Our capital expenditure program requires substantial liquidity and capital resources of approximately R$5.87 billion 
in the period from 2007 through 2010, of which we expect to spend R$960.0 million in 2007. 

We  have  funded  in  the  past,  and  we  plan  to  continue  to  fund,  these  expenditures  out  of  funds  generated  by 
operations  and  domestic  and  foreign  currency  borrowings  on  acceptable  terms.    A  significant  portion  of  our 
financing needs have  been  funded  by lenders controlled by  the  Federal  Government.    We also  benefit  from  long-
term financing from international multilateral agencies and development banks at attractive interest rates.  Changes 
in  the  policies  of  the  Federal  Government  regarding  the  financing  of  water  and  sewage  services,  or our  failure  to 
continue to benefit from long-term financing from domestic and international multilateral agencies and development 
banks  at  attractive  interest  rates  may  impair  our  ability  to  meet  our  obligations  or  finance  our  capital  expenditure 
program and could have a material adverse effect on us. 

14 

 
 
As a general rule, financial institutions and other institutions authorized to provide credit by the Central Bank may 
only  provide  loans  to  public  sector  entities,  such  as  us,  up  to  a  certain  percentage  of  the  entities’  shareholders’ 
equity.  Because of these limitations on our ability to obtain credit from domestic financial institutions, our options 
for  raising  funds,  other  than  the  cash  generated  by  our  operations,  consist  principally  of  borrowing  from 
international  financial  institutions  or  development  agencies  and  issuing  debt  securities  in  both  the  domestic  and 
international  capital  markets.    These  legal  limitations  could  adversely  affect  our  ability  to  continue  our  capital 
expenditure program. 

We are also subject to financial covenants limiting our ability to incur additional indebtedness, whether denominated 
in  reais  or  foreign  currency.    Under  these  covenants,  we  would  have  been  able  to  borrow  up  to  an  additional 
R$2,291.6  million  as  of  December  31,  2006.    These  contractual  limitations  may  prevent  us  from  completing  our 
capital expenditure program, which could have a material adverse effect on us. 

Potential costs of environmental compliance and potential environmental liability could have a material adverse 
effect on us. 

Our facilities are subject to extensive Brazilian federal, state and local laws and regulations relating to the protection 
of human health and the environment.  These laws and regulations limit or prohibit emissions or spills of effluents 
and toxic substances, such as raw sewage, produced in connection with our operations.  Current and past disposal 
and  emissions  practices  may  result  in  the  need  for  us  to  clean  up  or  retrofit  our  facilities  at  substantial  costs  and 
could result in substantial liabilities.   

We  could  be  subject  to  civil  public  actions  and  criminal,  administrative  and  other  civil  proceedings  for  non-
compliance  with  environmental  laws  and  regulations,  which  could  expose  us  to  civil  penalties  and  criminal 
sanctions, such as fines, closure orders and significant indemnification obligations.  Since environmental laws and 
their enforcement by Brazilian authorities are becoming more stringent, our capital expenditures and expenses  for 
environmental  compliance  may  increase  substantially.    Expenditures  required  for  compliance  with  environmental 
laws  and  regulations  may  result  in  reductions  in  other  strategic  investments  that  we  have  planned,  which  could 
negatively affect us.    

We  are  a  party  to  a  number  of  civil  public  actions  related  to  environmental  matters,  with  regard  to  which  we  are 
unable  to  calculate  our  estimated  amount  of  potential  liability,  especially  fines,  and  have  not  provisioned  any 
amounts.    In  addition,  due  to  more  stringent  enforcement  of  environmental  laws  by  Brazilian  courts,  we  may  be 
required  to  pay  substantial  fines  and  indemnifications  in  amounts  that  may  vary  widely  from  those  currently 
anticipated.  Any unfavorable judgment in relation to these proceedings or any material unforeseen environmental 
liabilities may have a material adverse effect on us. 

Any substantial monetary judgment against us in legal proceedings may have a material adverse effect on us. 

We are  a party to a number  of legal  proceedings  involving significant  monetary claims.   These  legal  proceedings 
include, among others, tax, labor, condemnation and other proceedings.  A substantial monetary judgment against us 
in  one  or  more  of  these  legal  proceedings  may  have  a  material  adverse  effect  on  us.    Based  on  advice  from  our 
lawyers,  we  have  provisioned  a  total  aggregate  amount  of  R$657.6  million  as  of  December  31,  2006  to  cover 
probable losses related to legal proceedings.  However, this provision does not cover all legal proceedings involving 
monetary  claims  filed  against  us  and  it  may  be  insufficient  to  cover  our  liabilities  related  to  these  claims.    Any 
unfavorable judgment in relation to these proceedings may have an adverse effect on us.  For more information, see 
“Item 8.A. Consolidated Statements and other Financial Information—Legal Proceedings.” 

Because we are not insured for all business-related and environmental-related contingencies, the occurrence of 
any of these events may have a material adverse effect on us. 

We  do  not  have  insurance  coverage  for  business  interruption  risk  or  for  liabilities  arising  from  contamination  or 
other  problems  involving  our  water  supply  to  customers.    In  addition,  we  do  not  have  insurance  coverage  for 
liabilities relating to non-compliance with environmental laws and regulations relating to our sewage services.  As a 
result, any major business interruption or environmental-related liability may have a material adverse effect on us. 

15 

 
 
Risks Relating to our Common Shares and ADSs 

The relative volatility and illiquidity of the Brazilian securities markets may substantially limit your ability to sell 
our common shares underlying the ADSs at the price and time you desire. 

Investing in securities that trade in emerging  markets, such as Brazil, often involves greater risk than investing in 
securities of issuers in the United States, and these investments are generally considered to be more speculative in 
nature.    The  Brazilian  securities  market  is  substantially  smaller,  less  liquid,  more  concentrated  and  can  be  more 
volatile than major securities markets in the United States.  Accordingly, although you are entitled to withdraw the 
common  shares  underlying  the  ADSs  from  the  depositary  at  any  time,  your  ability  to  sell  the  common  shares 
underlying  the  ADSs  at  a  price  and  time  at  which  you  wish  to  do  so  may  be  substantially  limited.    There  is  also 
significantly greater concentration in the Brazilian securities market than in major securities markets in the United 
States.    The  ten  largest  companies  in  terms  of  market  capitalization  represented  approximately  50.4%  of  the 
aggregate market capitalization of the BOVESPA as of December 31, 2006.  The top ten stocks in terms of trading 
volume accounted for approximately 45%, 51% and 46.4% of all shares traded on the BOVESPA in 2004, 2005 and 
2006, respectively. 

Restrictions on the movement of capital out of Brazil may impair the ability of holders to receive dividends and 
distributions on, and the proceeds of any sale of, the common shares underlying our ADSs. 

The Brazilian government may impose temporary restrictions on the conversion of Brazilian currency into foreign 
currencies and on the remittance to foreign investors of the proceeds of their investments in Brazil.  Brazilian law 
permits  the  government  to  impose  these  restrictions  whenever  there  is  a  serious  imbalance  in  Brazil’s  balance  of 
payments or there are reasons to foresee a serious imbalance. 

The Brazilian government imposed remittance restrictions in 1990.  Similar restrictions, if imposed, would impair or 
prevent the conversion of dividends, distributions, or the proceeds from any sale of common shares, as the case may 
be,  from  reais  into  U.S.  dollars  and  the  remittance  of  the  U.S.  dollars  abroad.    We  cannot  assure  you  that  the 
Brazilian government will not take similar measures in the future.  In such a case, the depositary for our ADSs will 
hold the reais it cannot convert for the account of the ADR holders who have not been paid.  The depositary will not 
invest the reais and it will not be liable for the interest. 

Investors who exchange ADSs for common shares may lose their ability to remit foreign currency abroad and to 
obtain Brazilian tax advantages. 

The Brazilian custodian for the common shares underlying our ADSs must obtain a certificate of registration from 
the  Central  Bank  to  be  entitled  to  remit  U.S.  dollars  abroad  for  payments  of  dividends  and  other  distributions 
relating  to  our  common  shares  or  upon  the  disposition  of  our  common  shares.    If  an  ADR  holder  decides  to 
exchange  ADSs  for  the  underlying  common  shares,  this  holder  will  be  entitled  to  continue  to  rely  —  for  five 
business  days  from  the  date  of  exchange  —  on  the  custodian’s  certificate  of  registration.    After  that  period,  the 
holder  may  not  be  able  to  obtain  and  remit  U.S.  dollars  abroad  upon  the  disposition  of  our  common  shares,  or 
distributions  relating  to  our  common  shares,  unless  he  or  she  obtains  his  or  her  own  certificate  of  registration  or 
register  under  Resolution  No. 2,689,  of  January 26,  2000,  of  the  Brazilian  National  Monetary  Council,  which 
entitles registered foreign investors to buy and sell on the Brazilian stock exchanges.  If the holder does not obtain a 
certificate  of  registration  or  register  under  Resolution  No. 2,689,  this  holder  will  generally  be  subject  to  less 
favorable tax treatment on gains with respect to our common shares. 

If  a  holder  attempts  to  obtain  his  or  her  own  certificate  of  registration,  the  holder  may  incur  expenses  or  suffer 
delays in the application process, which could delay his or her ability to receive dividends or distributions relating to 
our common shares or the return of his or her capital in a timely manner.  We cannot assure you that the custodian’s 
certificate  of  registration  or  any  foreign  capital  registration  obtained  by  a  holder  may  not  be  affected  by  future 
legislative changes, or that additional restrictions applicable to the holder, the disposition of the underlying common 
shares or the repatriation of the proceeds from disposition will not be imposed in the future. 

16 

 
 
A  holder  of  common  shares  or  ADSs  may  face  difficulties  in  protecting  his  or  her  interests  as  a  shareholder 
because we are a Brazilian mixed capital company. 

We are a mixed capital company (sociedade de economia mista) organized under the laws of Brazil, and all of our 
directors  and  officers  and  our  controlling  shareholder  reside  in  Brazil.    All  of  our  fixed  assets  and  those  of  these 
other persons are located in Brazil.  As a result, it may not be possible for a holder to effect service of process upon 
us  or  these  other  persons  within  the  United  States  or  other  jurisdictions  outside  Brazil  or  to  enforce  against  us  or 
these other persons judgments obtained in the United States or other jurisdictions outside Brazil.  Because judgments 
of  U.S.  courts  for  civil  liabilities  based  upon  the  U.S.  federal  securities  laws  may  only  be  enforced  in  Brazil  if 
certain requirements are met, a holder may face difficulties in protecting his or her interests in the case of actions by 
our directors, officers or our controlling shareholder than would shareholders of a corporation incorporated in a state 
or other jurisdiction of the United States.  In addition, under Brazilian law, none of our assets which are essential to 
our ability to render public services are subject to seizure or attachment.  Furthermore, the execution of a judgment 
against  our  controlling  shareholder  may  be  delayed  as  payment  of  the  judgment  must  be  made  pursuant  to  the 
State’s budget in a subsequent fiscal year.  None of the public property of our controlling shareholder is subject to 
seizure or attachment, either prior to or after judgment. 

The  protections  afforded  to  minority  shareholders  in  Brazil  are  different  from  those  in  the  United  States  and 
other jurisdictions and may be more difficult to enforce. 

Under Brazilian law, the protections afforded to minority shareholders are different from those in the United States 
and  other  jurisdictions.  In  particular,  the  case  law  with  respect  to  shareholder  disputes  is  less  developed  under 
Brazilian law than under US law and the laws of other jurisdictions and there are different procedural requirements 
for  bringing  shareholder  lawsuits,  such  as  shareholder  derivative  suits.  As  a  result,  in  practice  it  may  be  more 
difficult  for our minority shareholders to enforce their rights against us or our directors or controlling shareholder 
than it would be for shareholders of a non-Brazilian company. 

Actual or anticipated sales of a substantial number of our common shares could decrease the market prices of 
our common shares and ADSs. 

Sales  of  a  substantial  number  of  our  common  shares  —  or  the  anticipation  of  such  sales  —  could  decrease  the 
trading price of our common shares and ADSs.  As of December 31, 2006, we had 28,479,577,827 common shares 
outstanding,  including  14,313,511,867  shares  held  by  the  State.    As  a  consequence  of  the  issuance  of  common 
shares or sales by the State or other existing shareholders, the market price of our common shares and, by extension, 
our ADSs may decrease significantly.  As a result, a holder may not be able to sell his or her securities at or above 
the price he or she paid for them. 

Mandatory arbitration provisions in our by-laws may limit the ability of a holder of our ADSs to enforce liability 
under U.S. securities laws. 

Under our by-laws, any disputes among us, our shareholders and our management with respect to the application of 
Novo Mercado rules, Brazilian Corporate Law and the application of the rules and regulations regarding Brazilian 
capital  markets  will  be  resolved  by  arbitration  conducted  pursuant  to  the  São  Paulo  Stock  Exchange  Arbitration 
Rules in  the  São Paulo Stock Exchange Arbitration Chamber.   Any  disputes among  shareholders, including ADR 
holders, and disputes between us and our shareholders, including ADR holders, will also be submitted to arbitration.  
The State is currently not permitted by law to sell its control shares. As a result, a court in the United States might 
require that a claim brought by an ADR holder predicated upon the U.S. securities laws be submitted to arbitration 
in accordance with our by-laws.  In that event, a purchaser of ADSs would be effectively precluded from pursuing 
remedies under the U.S. securities laws in the U.S. courts. 

A  holder  of  our  common  shares  and  ADSs  might  be  unable  to  exercise  preemptive  rights  and  tag-along  rights 
with respect to the common shares. 

U.S. holders of  common shares and ADSs may not be  able to exercise  the preemptive  rights and tag-along rights 
relating  to  common  shares  unless  a  registration  statement  under  the  U.S.  Securities  Act  of  1933  is  effective  with 

17 

 
 
respect to those rights or an exemption from the registration requirements of the Securities Act is available.  We are 
not  obligated  to  file  a  registration  statement  with  respect  to  our  common  shares  relating  to  these  rights,  and  we 
cannot  assure  you  that  we  will  file  any  such  registration  statement.    Unless  we  file  a  registration  statement  or  an 
exemption from registration is available, an ADR holder may receive only the net proceeds from the sale of his or 
her preemptive rights and tag-along rights or, if these rights cannot be sold, they will lapse and the ADR holder will 
receive no value for them. 

A holder of our ADSs may find it more difficult than a holder of our common shares to exercise his or her voting 
rights at our shareholders’ meetings. 

Holders may exercise voting rights with respect to the common shares represented by our ADSs only in accordance 
with the deposit agreement relating to our ADSs.  There are no provisions under Brazilian law or under our by-laws 
that limit the exercise by ADR holders of their voting rights through the depositary with respect to the underlying 
common shares.  However, there are practical limitations upon the ability of ADR holders to exercise their voting 
rights  due  to  the  additional  procedural  steps  involved  in  communicating  with  these  holders.    For  example,  our 
common  shareholders  will  receive  notice  of  shareholders’  meetings  through  publication  of  a  notice  in  an  official 
government publication in Brazil and will be able to exercise their voting rights by either attending the meeting in 
person  or  voting  by  proxy.    ADR  holders,  by  comparison,  will  not  receive  notice  directly  from  us.    Instead,  in 
accordance with the deposit agreement, we will provide the notice to the depositary, which will, in turn, as soon as 
practicable  thereafter  mail  to  ADR  holders  the  notice  of  the  meeting  and  a  statement  as  to  the  manner  in  which 
instructions may be given by holders, but only if we request the depositary to do so.  To exercise their voting rights, 
ADR holders must then instruct the depositary as to voting the common shares represented by their ADSs.  Due to 
these procedural steps involving the depositary, the process for exercising voting rights may take longer for ADR 
holders  than  for  holders  of  common  shares.    ADSs  for  which  the  depositary  fails  to  receive  timely  voting 
instructions will not be voted at any meeting.

INFORMATION ON THE COMPANY 

4.A. History and Development of the Company 

Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo-SABESP  is  a  sociedade  de  economia  mista,  a  mixed 
capital company with limited liability of unlimited duration, duly organized and operating under Brazilian Corporate 
Law on Setember 6, 1973.  Our principal executive offices are located at Rua Costa Carvalho, 300, 05429-900 São 
Paulo,  SP,  Brazil.    Our  telephone  number  is  (55-11 3388-8000).    Our  agent  for  service  of  process  in  the  United 
States is CT Corporation System, with offices at 111 Eighth Avenue, New York, New York 10011.  As set forth in 
Article 2 of our by-laws, our corporate purpose is to plan, provide and operate basic sanitation services throughout 
the territory of the State of São Paulo, and sell these services and the related benefits that directly or indirectly arise 
in  connection  with  these  services.    Since  March 2006,  we  are  also  authorized  to  provide  these  services  in  all 
Brazilian territory and abroad. 

We believe we are one of the largest water and sewage service providers in the world based on customers in 2005.  
We operate water and sewage systems in the State of São Paulo in which the City of São Paulo, Brazil’s largest city, 
is  located.    According  to  the  Brazilian  Institute  of  Geography  and  Statistics  (Instituto  Brasileiro  de  Geografia  e 
Estatística),  or  IBGE,  the  State  of  São  Paulo  is  Brazil’s  most  populous  state  and  the  state  with  the  highest  gross 
domestic  product,  or  GDP,  in  Brazil.    We  had  net  revenue  from  sales  and  services  of  R$5,527.3 million 
(US$2,585.3 million)  and  net  income  of  R$778.9 million  (US$364.3 million)  for  2006.    We  had  total  assets  of 
R$18,000.0 million (US$8,419.1 million) and shareholders’ equity of R$9,018.5 million (US$4,218.2 million) as of 
December 31, 2006. 

We  provide  water  and  sewage  services  to  a  broad  range  of  residential,  commercial,  industrial  and  governmental 
customers  in  367  of  the  645  municipalities  in  the  State  of  São  Paulo,  including  the  City  of  São  Paulo.    We  also 
supply water on a wholesale basis to six municipalities in the São Paulo Metropolitan Region in which we do not 
operate water systems.  For the year ended December 31, 2006, the São Paulo Metropolitan Region (including the 
municipalities to which we provide water on a wholesale basis) and the Regional Systems accounted for 75.8% and 
24.2% of our gross revenue from sales and services, respectively. 

As of December 31, 2006, we provided water services to approximately 22.7 million people, approximately 59% of 
the urban population of the State of São Paulo, with a universalization of Water Coverage through 61,469 kilometers 
of water pipes and mains to approximately 6.6 million water connections.  As of December 31, 2006, we provided 
sewage  services  to  approximately  18.5 million  people  through  39,126  kilometers  of  sewer  lines  to  approximately 
5.0 million sewage connections.  In addition, we currently sell water on a wholesale basis to six municipalities with 
a total estimated population of approximately 3.2 million. 

The State, our controlling shareholder, is required by our by-laws and State law to own at least one-half plus one of 
our  common  (voting)  shares.    The  State  currently  owns  50.3%  of  our  outstanding  common  shares.    As  a  mixed 
capital company, we are an integral part of the governmental structure of the State.  Our strategy and major policy 
decisions  are  formulated  in  conjunction  with  the  Sanitation  and  Energy  Secretariat  of  the  State  of  São  Paulo 
(Secretaria de Saneamento e Energia do Estado de São Paulo) as part of the overall strategic planning for the State.  
The  majority  of  the  members  of  our  board  of  directors  and  our  board  of  executive  officers  are  nominated  by  the 
State Council for Protection of Capitals of the State (Conselho de Defesa de Capitais do Estado de São Paulo), or 
CODEC, a State agency presided over by the Secretary of the State Treasury and reporting directly to the Governor. 

In addition, our capital expenditure budget is subject to approval by the legislature of the State and is approved in 
conjunction  with  the  budget  of  the  Sanitation  and  Energy  Secretariat  of  the  State  of  São  Paulo  (Secretaria  de 
Saneamento e Energia do Estado de São Paulo) as a whole.  Our financial statements and accounting records are 
subject to review by the State Accounts Tribunal (Tribunal de Contas), as are all accounts of the State. 

OUR STRENGTHS 

We believe that our strong business position and future prospects relate to the following strengths: 

19 

 
 
Well-established business with significant size and scale.  We believe we are one of the largest water and 
sewage  service  providers  in  the  world  based  on  population  served  in  2005.    We  provide  water  services 
directly  and  through  other  public  companies  to  approximately  25.9  million  people  (including  the 
municipalities to which we provide water services on a wholesale basis), having a universalization of Water 
Coverage  as  of  December  31,  2006,  and  sewage  services  to  approximately  18.5 million  people,  having  a 
Sewage Coverage Ratio of 78% as of December 31, 2006.  From 2003 to 2006, our net revenue from sales 
and services has increased by an average of 10.2% per year. 

Operations  in  Brazil’s  most  populous  and  wealthy  state.    The  State  of  São  Paulo,  part  of  the  most 
developed and economically active region of Brazil, is the most populous state in Brazil, with an estimated 
population of 40.8 million as of December 31, 2006.  The City of São Paulo had an estimated population of 
10.8 million as of December 31, 2006, with 19.5 million inhabitants in the São Paulo Metropolitan Region.  
Based on its GDP, the State of São Paulo is the wealthiest state and largest economy in Brazil.  The GDP of 
the  State  of  São  Paulo  was  approximately  R$546.6 billion  in  2004,  representing  approximately  31%  of 
Brazil’s total GDP.  The State of São Paulo generates more revenues from water and sewage services than 
any other Brazilian state.   

High-quality  operations.    We  believe  that  we  adhere  to  high  standards  of  service  and  utilize  the  best 
available  technology  in  the  sanitation  business.    All  of  our  water  quality  laboratories  in  the  São  Paulo 
Metropolitan Region and all of our ten laboratories in the Regional Systems have received ISO 9001/2000 
certification  and  three  in  the  Regional Systems  have received ISO 17025 certification  with respect to the 
quality of our management systems to respond to clients’ needs and the technical ability of our laboratories 
to produce results.  We believe our technology enhances the efficiency and quality of our operations. 

Access to low-cost and diverse sources of financing.  Strong cash flow generation from our operations and 
compliance  with  financial  covenants  place  us  in  a  privileged  position  in  our  industry  to  obtain  low  cost, 
long-term  financing  from  Brazilian  public  banks  and  international  multilateral  agencies  and  development 
banks.  In addition, we are not dependent upon one or few sources of financing.  We benefit from various 
alternatives  of  funding  available  in  the  Brazilian  and  international  markets  for  our  working  capital  needs 
and our capital expenditure programs.   

Strong  corporate  governance  practices.    In  2002,  we  joined  the  Novo  Mercado,  the  highest  corporate 
governance  listing  segment  of  the  São  Paulo  Stock  Exchange  (Bolsa  de  Valores  de  São  Paulo  – 
BOVESPA).    We  are  committed  to  maintaining  certain  corporate  governance  practices  and  disclosure 
requirements  in  addition  to  those  already  required  under  Brazilian  law.    These  corporate  governance 
practices  have  require  us  to  increase  shareholders’  rights  and  to  enhance  the  quality  of  information 
provided to our shareholders. 

Expansion opportunities.  We had a Sewage Coverage Ratio of 78% as of December 31, 2006, and plan to 
increase this level to 84% by 2010 by adding over 791,700 sewage connections.  Since January 1, 1997, we 
have obtained concessions for 32 additional municipalities (representing a total population of 2.2 million).  
In addition, there are municipalities in the State of São Paulo in which we currently do not operate water or 
sewage concessions or to which we currently supply water solely on a wholesale basis, which represent a 
total  population  of  approximately  15.7  million.    Our  strong  presence  in  the  State  and  experience  in 
providing  water  and  sewage  services  place  us  in  a  privileged  position  to  expand  our  Sewage  Coverage 
Ratio in municipalities where we only provide water services and to expand our water and sewage services 
to municipalities where we are not yet operating, not only in the State of São Paulo but also in other states 
of Brazil and abroad. 

OUR STRATEGY  

Our  mission  is  to  make  public  sanitation  services  universally  available  in  the  State  of  São  Paulo  and  to  provide 
quality services in both the national and international markets.  To this end, our strategic objectives are based upon 
the  guiding  principles  of  growth,  quality,  universalization  of  water  services,  social,  economic  and  environmental 
sustainability, as well as our political and institutional relationships.  We seek to implement these guiding principles 
through the following strategies: 

20 

 
 
Continue to reduce operating costs and increase productivity and profitability.  We intend to continue our 
efforts  to  reduce  operating  costs  and  increase  productivity  and  profitability.    To  this  end,  we  plan  to 
improve the management of our assets, as well as continue reducing our total salary and payroll expenses 
by decreasing the number of our employees, automating some of our operations, streamlining operational 
processes,  implementing  integrated  planning  and  further  investing  in  internal  technological  research  and 
development.  We are also continuing our efforts to improve our collection of overdue accounts receivable 
from  municipalities  to  which  we  provide  water  on  a  wholesale  basis,  from  the  State  and  from  other 
governmental  entities.    We  are  actively  pursuing  the  overdue  amounts  and  in  some  cases  exploring 
opportunities to swap these amounts for rights and infrastructure to operate water and sewage systems. 

Ensure  the  quality  and  availability  of  our  services  in  our  existing  service  area.    Our  goal  is  to  maintain 
universal coverage of water services with a high standard of quality and availability.  We intend to continue 
providing  universal  water  services  and  meet  population  growth  by  adding  652,100  water  connections  by 
2010 and to increase our Sewage Coverage Ratio to 84% by 2010.  To ensure the quality and availability of 
our  services,  we  also  intend  to  improve  customer  relations  by  shortening  response  times  for  customer 
installations as well as through a focused public relations program to enhance our image.  In addition, we 
are  also  developing  short,  medium  and  long-term  marketing  strategies,  such  as  client  segmentation  and 
tailor-made solutions for each type of client, which we believe will help us increase our customers’ base. 

Maintain our operating geographic base.  We intend to maintain our operating base through the execution 
of  new  agreements.    To  this  end,  we  are  also  seeking  to  develop  closer  relationships  with  the  municipal 
governments that we serve to increase customer loyalty and thereby increase our revenues.     

Continue to expand our existing service areas and provide our services in other municipalities.  Our goal is 
to  expand  sewage  collection  and  treatment  services.    A  significant  portion  of  our  capital  expenditure 
program, which will require total expenditures of approximately R$5.87 billion between 2007 and 2010, is 
designed  to  achieve  this  goal.    We  also  regularly  explore  the  possibility  of  executing  agreements  for  the 
provision of water and sewage services in municipalities of the State of São Paulo in which we currently 
have no operations or to which we currently supply water solely on a wholesale basis, representing a total 
population  of  approximately  15.7  million.  We  evaluate  possible  expansion  opportunities  in  terms  of 
proximity  to  our  existing  service  areas  to  maximize  return  on  investment  and  improve  our  financial 
performance.  We also intend to study, and take advantage of, opportunities in other Brazilian states and in 
other countries to expand our services and increase our market share. 

Set our tariffs to cover our costs of operations and to provide a return on investment.  Until the definition 
of the entity responsible for establishing tariffs regulations, we intend to continue adjusting our tariffs for 
water and sewage services according to the formula we currently use, which covers our operating costs and 
other  expenses,  accounts  for  inflation,  and  provides  for  return  on  investment.    We  generally  adjust  our 
tariffs once a year, usually in the month of August, for a period of at least 12 months.  We increased our 
tariffs by 9.0% on August 31, 2005 and by 6.71% on August 31, 2006.  To ensure proper adjustment of our 
tariffs and  higher return on  investment, we intend  to  restructure  our tariffs with  values based on costs of 
services for all segments or clients, except for the low-income population, which should be subsidized.   

Continue  to  diversify  sources  of  financing  and  reduce  levels  of  indebtedness.    Our  total  financial 
indebtedness decreased by 5%, from R$6,664.2 million in 2005 to R$6,326.7 million in 2006.  In 2006, we 
raised  funds  in  the  Brazilian  capital  market  through  a  new  funding  instrument  called  Fundo  de 
Investimentos em Direitos Creditórios, or FIDC.  This instrument involves the securitization of receivables, 
and enabled R$250.0 million to be raised at a significantly reduced cost.  As a debt management strategy, 
we  used  part  of  these  funds  for  the  early  redemption  of  higher  cost  indebtedness  in  the  Brazilian  money 
market.  Based  on  our  pre-refinancing  strategy,  we  carried  out  a  tender  offer  to  promote  the  partial 
redemption of  our 12% notes  due 2008,  in the amount of  US$225.0  million, with  funds raised through  a 
new issuance of 7.5% notes due 2016, in the amount of US$140.0 million. 

Improve operating efficiency and reduce water losses.  We seek to reduce both physical water losses and 
non-physical water losses.  We are continuing our efforts to reduce physical water losses through, among 
other things, the replacement and repairing of water mains and pipes and installation of probing and other 

21 

 
 
equipment.  We are continuing our program of strategically locating pressure-regulating valves throughout 
our  water  system,  which  regulate  water  pressure  at  a  variable  rate  corresponding  to  consumption  in  the 
relevant sector.  We are also striving to reduce physical water losses by continuing to shorten the average 
time to detect and repair leaks in our systems.  We intend to reduce non-physical water losses by upgrading 
and  replacing  inaccurate  water  meters  and  through  increased  outsourcing  of  meter  reading  activities  to 
third-party contractors outside the São Paulo Metropolitan Region.  In particular, we are replacing the water 
meters  for  our  industrial  and  commercial  customers,  as  well  as  increasing  the  rate  at  which  we  read  the 
meters for these customers in each case to minimize losses. 

We believe that our overall strategy will enable us to meet the demand for high-quality water and sewage services in 
the State of São Paulo, in other Brazilian states and abroad and, at the same time, bolster our results of operations 
and our financial condition and enhance shareholder value. 

State of São Paulo 

The  State  of  São  Paulo  is  one  of  26  states  that,  together  with  the  Federal  District  of  Brasília,  constitute  the 
Federative Republic of Brazil.  The State of São Paulo is located in the southeastern region of the country, which is, 
according to IBGE, the most developed and economically active region of Brazil, and which includes the States of 
Minas Gerais, Espírito Santo and Rio de Janeiro.  The State of São Paulo lies between the States of Rio de Janeiro 
and  Minas  Gerais to the  north, the State of Paraná to  the  south,  Mato  Grosso do  Sul to the  west  and  the  Atlantic 
Ocean to the east. 

The State of São Paulo occupies 3.0% of Brazil’s land mass and encompasses an area totaling approximately 96,000 
square  miles.    According  to  the  State  of  São  Paulo  Data  System  (Fundação  Sistema  Estadual  de  Análises  de 
Dados—SEADE), the State of São Paulo had an estimated population as of December 31, 2006 of 40.8 million. 

As of December 31, 2006, the City of São Paulo, the State of São Paulo’s capital, had an estimated population of 
10.8 million,  with  19.5 million  inhabitants  in  the  greater  São  Paulo  Metropolitan  Region.    The  São Paulo 
Metropolitan Region encompasses 39 cities and is the second largest metropolitan area in the Americas and among 
the  four  largest  metropolitan  areas  in  the  world,  according  to  the  United  Nations’  World  Urbanization  Prospects, 
2000 Revision.  The São Paulo Metropolitan Region accounted for approximately 48% of the population of the State 
of São Paulo as of December 31, 2006. 

According  to  IBGE,  in  2004  ,  the  most  recent  year  for  which  this  data  is  available,  the  GDP  of  the  State  of  São 
Paulo  was  approximately  R$  546.6   billion,  representing  approximately  31%  of  Brazil’s  total  GDP,  making  it  the 
largest economy of any state in Brazil, based on GDP.  The State of São Paulo is the leading Brazilian state in terms 
of  manufacturing  and  industrial  activity,  also  according  to  IBGE,  with  a  strong  position  in  car  manufacturing, 
pharmaceuticals, computer  production, steel  making  and  plastics, among others, as  well as  the  leading position in 
the banking and financial services industries.  The State of São Paulo is the most important exporting state in Brazil, 
according to the Brazilian  Ministry of Development, Industry and Foreign Trade (Ministério do Desenvolvimento, 
Indústria e Comércio Exterior). 

History 

Until the end of the 19th century, water and sewage services in the State of São Paulo were generally provided by 
private companies.  In 1877, the Province of São Paulo granted a concession for the provision of water and sewage 
services  to  Companhia  Cantareira  de  Água  e  Esgotos.    In  1893,  the  Government  of  the  Province  of  São  Paulo 
assumed responsibility for the provision of water and sewage services from the Companhia Cantareira de Água e 
Esgotos and formed the Office of Water and Sewers (Repartição de Água e Esgotos), a governmental agency.  Since 
that  time,  water  and  sewage  services  in  the  São  Paulo  Metropolitan  Region  have  been  administered  by  the 
government of the State.  Historically, water and sewage services in substantially all other municipalities of the State 
were  administered  by  the  municipalities  directly  either  by  municipal  water  and  sewage  departments  or  through 
autarquias  of  the  municipal  government.    Autarquias  are  relatively  autonomous  public  bodies  with  separate  legal 
standing, assets and revenues, created by law to undertake administration of public services, which are considered to 
be better managed by a decentralized administrative and financial structure. 

22 

 
 
In 1954, in response to  dramatic population growth in the São Paulo Metropolitan Region, the government of the 
State created the Department of Water and Sewers (Departamento de Águas e Esgotos), as an autarquia of the State.  
The Department of Water and Sewers provided water and sewage services to various municipalities in the São Paulo 
Metropolitan Region. 

A major restructuring of the entities providing water and sewage services in the State of São Paulo occurred in 1968 
with  the  creation  of  the  Companhia  Metropolitana  de  Água  de  São  Paulo,  or  COMASP,  which  purpose  was  to 
provide potable water on a wholesale basis for public consumption in the municipalities making up the São Paulo 
Metropolitan Region.  All assets relating to the production of potable water for the São Paulo Metropolitan Region 
previously  owned  by  the  Department  of  Water  and  Sewers  were  transferred  to  COMASP.    In  1970,  the 
Superintendência de Água e Esgoto da Capital, or SAEC, was created by the government of the State to distribute 
water and collect sewage in the City of São Paulo.  All assets previously owned by the Department of Water and 
Sewers in connection with these activities were transferred to SAEC.  Also in 1970, the State created the Companhia 
Metropolitana de Saneamento de São Paulo, or SANESP, to provide sewage treatment services for the São Paulo 
Metropolitan Region.  All assets previously owned by the Department of Water and Sewers in connection with those 
activities were transferred to SANESP.  The Department of Water and Sewers was subsequently closed. 

On June 29, 1973, COMASP, SAEC and SANESP merged to form our company with the purpose of implementing 
the  directives  of  the  Brazilian  government  set  forth  in  the  National  Water  Supply  and  Sanitation  Plan  (Plano 
Nacional  de  Saneamento).    The  National  Water  Supply  and  Sanitation  Plan  was  a  program  sponsored  by  the 
Brazilian  government,  which  financed  capital  investments  in,  and  assisted  in  the  development  of,  state-controlled 
water  and  sewage  companies.    Since  our  formation,  other  State  governmental  and  State-controlled  companies 
involved in water supply and sewage collection and treatment in the State of São Paulo have been merged into us. 

Corporate Organization 

During 2004, we reorganized our corporate management structure.  As a result, we currently have six management 
divisions, each of which is supervised by one of our executive officers. 

The allocation of responsibilities among the executive officers is made by the board of directors, in accordance with 
the  by-laws  and  following  receipt  of  an  initial  proposal  from  the  Chief  Executive  Officer.    The  Chief  Executive 
Officer  is  responsible  for  coordinating  all  management  divisions  in  accordance  with  the  policies  and  directives 
established by our board of directors and board of executive officers, performing the coordination, evaluation and 
control  of  all  functions  related  to  senior  management,  strategic  planning,  corporate  organization,  corporate 
communication,  audit,  ombudsman,  new  businesses  and  concession  negotiation.    The  executive  officers  that  are 
below the Chief Executive Officer are:  

• 

• 

• 

• 

the  Corporate  Management  Officer,  who  is  responsible  for  marketing,  human  resources  and

We  experienced  significant  operational  and  financial  problems  beginning  in  the  mid-1980’s,  which  culminated  in 
1994.  These problems were due, in part, to adverse economic conditions in Brazil prior to implementation of the 
Real Plan in mid-1994, but also to our position as a State-controlled company which financial performance was then 
only a secondary consideration of the State. 

We also had significant and increasing levels of unpaid account receivables from our customers, including the State 
and municipal governments. 

In 1995, we, in conjunction with the administration of the State, initiated a “recovery” program designed to restore 
our business operations and financial condition, including the organizational restructuring, the implementation of the 
initial stages of our strategy and the development of a new “for-profit” orientation. 

We believe that our continuing recovery program and the continuing implementation of our overall strategy have, to 
date,  permitted  a  recovery  in  terms  of  our  business  operations  and  financial  performance,  which  we  expect  to 
provide the basis for our long-term operational and financial development. 

Capital Expenditure Program  

Our capital expenditure program is designed to improve and expand our water and sewage system and to increase 
and protect our water sources in order to meet the growing demand for water and sewage services in the State of São 
Paulo.    Our  capital  expenditure  program  has  four  specific  goals  in  the  municipalities  we  serve:  (1)  to  continue  to 
meet the maximum demand for treated water; (2) to expand the percentage of households connected to our sewage 
system; (3) to increase the treatment of sewage collected; and (4) to increase operating efficiency and reduce water 
losses. 

From 1998 through 2006, our capital expenditure program included capital expenditures totaling R$6.4 billion in the 
aggregate, primarily to build up our infrastructure and for our program to reduce water losses.  We have budgeted 
investments in the amount of approximately R$5.87 billion from 2007 through 2010.  We invested R$678.2 million 
and R$904.9 million in 2005 and 2006, respectively. 

The following table sets forth our planned capital expenditures for water and sewage for the years indicated.

Our capital expenditure program from 2007 through 2010 will continue to focus on achieving our targets by making 
regular  investments  in  and  expanding  our  infrastructure  as  well  as  making  investments  in  our  program  for  the 
reduction of water losses throughout the 367 municipalities that we serve.  The following is a description of four of 
the principal projects in our capital expenditure program. 

Metropolitan Water Program 

Demand  for  our  water  services  has  grown  steadily  over  the  years  in  the  São  Paulo  Metropolitan  Region  and  has 
exceeded  at  times  the  capacities  of  our  water  systems  there.    As  a result,  prior  to  September  1998,  certain  of  our 
customers in this region received water only on certain days of the week.  We refer to this as “rotation.”  In order to 
remedy this situation, we implemented the Metropolitan Water Project to improve regular water supply to the entire 
São  Paulo  Metropolitan  Region.    This  program  was  terminated  in  2000,  but  we  have  maintained  our  investment 
projections  for  the  São  Paulo  Metropolitan  Region.    In  2005  and  2006,  we  invested  R$75.0  million  and  R$53.0 
million, respectively, in this region. 

Tietê Project 

The  Tietê  River  crosses  the  São  Paulo  Metropolitan  Region  and  receives  most  of  the  region’s  run-off  and 
wastewater.    The  environmental  status  of  the  river  reached  a  critical  level  in  1992.    As  a  way  of  reversing  the 
situation,  the  State  of  São  Paulo  created  a  recovery  program  to  save  the  river.    The  Tietê  Project  is  designed  to 
reduce pollution of the Tietê River by installing sewage collection lines along the banks of the Tietê River and its 
tributaries.  These lines collect raw sewage and deliver it to our sewage treatment facilities.  We completed the first 
phase of the program during the years of 1992 and 1998. 

In connection with the first phase of the Tietê Project, in June 1998, we completed construction of three additional 
sewage  treatment  facilities  and  invested  a  total  of  US$900.0 million,  of  which  US$450.0 million  was  financed  by 
the  Inter-American  Development  Bank  and  US$450.0 million  was  funded  by  us.    As  of  December  31,  2006,  we 
owed  US$265.4  million  to  the  Inter-American  Development  Bank  for  the  financing  it  provided.  For  further 
information  on  the  agreement  entered  into  with  the  Inter-American  Development  Bank,  see  “Item  5.B.  Operating 
and  Financial  Review  and  Prospects—Liquidity  and  Capital  Resources—Capital  Sources.”    We  now  provide 
secondary treatment to approximately 58% of the sewage collected in the São Paulo Metropolitan Region.  The five 
principal sewage treatment facilities in the São Paulo Metropolitan Region have an aggregate installed capacity of 
18  cubic  meters  of  sewage  per  second  and  currently  treat  an  aggregate  of  12  cubic  meters  of  sewage  per  second.  
Currently, raw sewage is delivered to our secondary treatment facilities along the Tietê River and the Tamanduateí 
River  before  treated  sewage  is  discharged  into  those  rivers.    We  plan  to  build  additional  collection  lines  to  direct 
more raw sewage to our treatment facilities. 

We are currently in the second phase of the Tietê Project, for which we budgeted for additional capital expenditures 
of approximately US$400.0 million from 2000 through 2007, US$200.0 million of which is financed by the Inter-
American Development Bank.  We have also entered into a loan agreement and an on-lending agreement with the 
Brazilian National Bank for Social and Economic Development (Banco Nacional de Desenvolvimento Econômico e 
Social),  or  BNDES,  for  R$60.0  million  and  R$180.0  million,  respectively,  to  finance  this  second  phase.    Until 
December 31, 2006, we had invested US$336.9 million in this phase of the Tietê Project. 

The main objective of this second phase is the continuity of the expansion and optimization of the sewage systems 
of the São Paulo Metropolitan Region, primarily focusing on actions that allow the destination of a higher volume of 
raw sewage to the sewage treatment facilities that were built in the first phase of the Tietê Project. 

As  part  of  the  second  phase  of  the  Tietê  Project,  we  implemented  the  geographic  information  system  named 
SIGNOS.    SIGNOS  is  a  management  information  system  which  automates  and  integrates  various  business 
processes,  including  project  management,  maintenance,  operations  and  customer  service  and  maps  out  our  entire 
municipal infrastructure in the São Paulo Metropolitan Region.  In addition, this phase included the undertaking of a 
project  aimed  at  evaluating  and  potentially  revising  our  current  tariff  structure  in  order  to  cover  the  systems 
operation and maintenance costs and appropriately remunerate current and future investments.  This project is also 
financed by our loan with the Inter-American Development Bank.  

25 

 
 
Regional Systems Investment Programs 

We  currently  have  a  number  of  projects  in  progress  and  planned  for  the  Regional  Systems,  including  projects 
relating  to  abstraction  of  water  and  collection,  removal  and  final  disposal  of  sewage.    We  spent  R$212.0  million, 
R$222.0 million and R$331.2 million on these projects in 2004, 2005 and 2006, respectively, and we have budgeted 
for additional capital expenditures approximately R$2.4 billion (unaudited) from 2007 through 2010.  

Environmental Recovery Program for the Santos Metropolitan Region 

On August 6, 2004, we entered into a credit agreement with Japan Bank for International Cooperation, or JBIC, for 
the financing of the Environmental Recovery Program for the Santos Metropolitan Region, which was guaranteed 
by  the  Federative  Republic  of  Brazil,  for  a  total  amount  of  R$382.8  million.    For  further  information  on  the 
agreement entered into with the JBIC, see “Item 5.B. Operating and Financial Review and Prospects—Liquidity and 
Capital Resources—Capital Sources.”  The total investment to be made with respect to this project is approximately 
R$1.1  billion  and  the  balance  will  be  our  responsibility.    The  first  disbursements  under  this  agreement  began  in 
August 2005 with the commencement of the management agreement.  We expect that construction works will begin 
in  the  second  quarter  of 2007.   The  main  goals of  this  program are to  improve and expand the water and sewage 
systems in the municipalities comprising the Santos Metropolitan Region. 

Research and Development 

Our  policy  is  to  invest  continually  in  the  modernization  of  equipment  and  in  the  technology  needed  to  identify, 
evaluate  and  improve  our  provision  of  basic  sanitation  services  while  promoting  environmental  protection  and 
maintaining  our  competitiveness  and  profitability.    Our  research  and  development  function  is  divided  into 
committees according to strategy and complexity.  In 2004, 2005 and 2006, we spent R$4.2 million, R$4.7 million 
and  R$4.9  million,  respectively,  on  research  and  development.    We  have  also  partnered  with  several  research 
institutions.   

4.B. Business Overview 

Our Operations 

We  provide  water  and  sewage  services  to  367  municipalities  in  the  State  of  São  Paulo  either  under  concession 
contracts or under another form of legal arrangement.  We also provide water services on a wholesale basis. 

Because  of  the  enactment  of  new  legislation  regarding  basic  sanitation  in  Brazil,  we  currently  operate  under  two 
different  contractual  environments:  (1)  for  the  concession contracts that have already expired,  we  will negotiate  a 
new contract model that follows the terms and conditions of the new legislation, and (2) for the concession contracts 
that  will  expire,  we  will  continue  to  operate  under  the  terms  and  conditions  of  the  previous  concession  contracts, 
except in circumstances where the new legislation is automatically applicable.  For further information on this topic, 
see  “— The Basic Sanitation Law.”  

The new basic sanitation legislation, Law No. 11,445, establishes the date of December 31, 2010 as the deadline for 
water  and  sewage  services  companies,  such  as  us,  to  regularize  the  provision  of  water  and  sewage  services  to 
municipalities, in case there is no formal concessions to provide services to them. 

Concessions 

Under the Brazilian Constitution, the authority to develop public water and sewage systems is shared by the states 
and municipalities, with the municipalities having primary responsibility for providing water and sewage services to 
their residents.  The Constitution of the State of São Paulo provides that the State shall assure the correct operation, 

26 

 
 
 
 
necessary  expansion  and  efficient  administration  of  water  and  sewage  services  in  the  State  of  São  Paulo  by  a 
company under its control. 

Under the terms of the new basic sanitation law, Law No. 11,445, existing concessions will remain in effect until 
payment  of  compensation  is  made  based  on  the  valuation  of  investments.    The  new  law  provides  that  our  new 
concession contracts be planned, overseen and regulated by the municipalities together with the State under a new 
model of associated management that will allow for better control, supervision, transparency and efficiency in the 
provision of public services.  

We  provide  water  and  sewage  services  to  367  municipalities  in  the  State  of  São  Paulo,  of  which  324  we  operate 
pursuant  to  concessions  granted  by  the  municipalities.    Substantially  all  of  these  concessions  have  30-year  terms.  
Until  December  31,  2006,  120  of  our  concessions  had  expired,  all  of  which  are  under  negotiation.    In  2007,  53 
concessions will expire.  From 2008 through 2034, 150 concessions will expire.  The remainder of the concessions is 
for an undetermined period of time.  Some of the expired concession contracts have been extended for a short term 
while we negotiate the terms and conditions of the termination of the previous contract and the terms and conditions 
for the new final contract with each  municipality.  Despite the expiration of the contracts, we continue to provide 
water and sewage services to all municipalities regardless of whether we have entered into contracts with them.   

In  February  2006,  we  created  a  new  internal  division  to  manage  the  renewal  of  expiring  concessions.    The  main 
responsibility of this division, which reports directly to the Chief Executive Officer, is to maintain the existing base 
of municipalities that we operate and formalize contracts under the new model of associated management. 

The current concessions are based on a standard form of contract between us and the relevant municipality.  Each 
contract must receive the prior approval of the legislative council of each municipality.  The principal terms of the 
concession contracts are as follows: 

• 

• 

• 

• 

• 

• 

We assume all responsibility for providing water and sewage services in the municipality. 

We  may  determine  and  collect  the  tariffs  for  our  services  without  prior  authorization  of  the 
municipality. 

The assets comprising the existing  municipal water and sewage systems are transferred from the 
municipality  to  us.    Until  1998,  we  acquired  municipal  concessions  and  the  existing  water  and 
sewage  assets  in  exchange  for  our  common  shares  issued  at  book  value.    Since  1998,  we  have 
acquired concessions and water and sewage assets by paying the municipality an amount equal to 
the present value of 30 years of estimated cash-flows, assuming at least a 12.0% discount factor to 
us, from the concession being acquired.  Payment is made in cash.  

As a  general  rule,  to  date we are exempt  from  municipal  taxes,  and no royalty  is payable to the 
municipality with respect to the concession. 

We are granted rights of way on municipal property for the installation of water pipes and mains 
and sewer lines. 

On termination of the concession, or upon cancellation for any reason, we are required to return 
the  assets  comprising  the  municipality’s  water  and  sewage  system  to  the  municipality  and  the 
municipality  is  required  to  pay  us  the  non-amortized  book  value  of  our  assets  relating  to  the 
concession. 

Under concession contracts executed prior to 1998, we were reimbursed for these assets through payment of either: 

• 

• 

the book value of the assets; or 

the  market  value  of  the  assets  as  determined  by  a  third-party  appraiser  in  accordance  with  the 
terms of the specific contract. 

27 

 
 
Concession  contracts  we  have  entered  into  since  1998  provide  that  after  a  period  of  30  years  from  the 
commencement  of  the  concession,  the  total  value  of  the  concession  and  assets  will  be  amortized  to  zero  on  our 
books  and  we  receive  no  payment  for  the  assets.    If  the  concession  is  terminated  prior  to  the  end  of  the  30-year 
period,  we  are  paid  an  amount  equal  to  the  present  value  of  the  cash-flow  from  the  concession  over  the  years 
remaining  in  the  concession,  using  the  same  assumptions  used  to  determine  the  value  of  the  concession  at  its 
inception (adjusted for inflation). 

Following  the  enactment  of  the  Concessions  Law  (Law  No.  8,987/95)  and  of  the  Consortium  Law  (Law  No. 
11,107/05), the new contracts will adopt the new regime.  This new regime gives municipalities a greater role and 
sets out more clearly the provision of services and the responsibilities of the parties.  Therefore, all new contracts 
acquired  by  us  and  the  new  contracts  to  be  executed  after  the  expiration  of  the  concessions  will  follow  this  new 
contract model.  See “—Government Regulation—Public Consortia Law.” 

Our  new  contract  model  follows  the  provisions  of  the  newly  enacted  Law  No.  11,445.    The  main  contractual 
provisions  are:  joint  execution  of  responsibilities  related  to  planning,  supervision  and  regulation  of  services, 
appointment of regulatory authority of services and periodic disclosure of accounts, among others. 

Municipalities  have  the  inherent  power  under  Brazilian  law  to  terminate  concessions  prior  to  their  contractual 
expiration  dates  for  reasons  of  public  interest.    The  municipalities  of  Diadema  and  Mauá,  two  municipalities  we 
previously  served,  terminated  our  concessions  in  February  1995  and  December  1995,  respectively.    The 
municipality  of  Diadema  terminated  our  concession  after  asserting  that  we  did  not  provide  adequate  water  and 
sewage  services,  while  the  municipality  of  Mauá  did  so  with  our  consent.    However,  we  currently  serve  both 
municipalities through the sale of water on a wholesale basis. 

We  currently  do  not  anticipate  that  other  municipalities  will  seek  to  terminate  concessions  due  to  our  close 
relationship with municipal governments, recent improvements in the water and sewage services we provide and the 
obligation of the municipality to repay us for the return of the concession as described above.  We cannot be certain, 
however, that other municipalities will not seek to terminate their concessions in the future. 

In addition, there is currently ongoing litigation with respect to  municipalities that intend to expropriate our water 
and  sewage  systems  or  to  terminate  concession  contracts  prior  to  paying  us  any  indemnification.    For  example, 
among others, we have pending proceedings with the municipalities of Santos, Sandovalina, Presidente Prudente and 
Itapira.    For  a  detailed  discussion  on  these  proceedings,  see  “Item  8.A.  Financial  Information—Consolidated 
Statements and other Information—Legal Proceedings—Other Legal Proceedings.” 

We are also defendants in legal proceedings initiated by municipalities seeking to require us to exhibit documents 
and information in connection with our concessions.  These legal proceedings involve the municipalities of Guariba, 
Ribeirão  Pires,  Itupeva and  Monte  Mor.   For a  detailed  discussion of  these  proceedings,  see “Item  8.A. Financial 
Information—Consolidated Statements and other Information——Legal Proceedings—Other Legal Proceedings.” 

Operations in the São Paulo Metropolitan Region and in Other Metropolitan Regions 

We do not hold a formal concession to provide water and sewage services to the City of São Paulo, which accounts 
for  56.8%  of  our  revenue,  and  to  40  other  municipalities  in  the  State  of  São  Paulo.    None  of  these  other 
municipalities  has  a  significant  population,  other  than  the  municipality  of  Santos,  which  has  a  population  of 
approximately 426,000.  We believe that we have a vested and exclusive right to provide water and sewage services 
to the City of São Paulo and these other municipalities based, in some cases, upon a deed (escritura pública) and, 
also among other things, based on our ownership of the water and sewage systems serving the City of São Paulo and 
these other municipalities and certain succession rights resulting from the merger that formed us. 

The  new  basic  sanitation  law,  Law  No.  11,445,  provides  that,  in  case  of  termination  of  the  relationship  with  the 
aforementioned municipalities with which we have not entered into a concession contract, an indemnification should 
be paid by the municipalities to us, in amounts to be calculated by studies and appraisals.  

28 

 
 
Wholesale Operations 

We provide wholesale water services to six municipalities, including the municipalities of Diadema and Mauá.  In 
addition,  until  December  2003  we  provided  wholesale  water  services  to  the  municipality  of  São  Bernardo  do 
Campo.  In December 2003, we acquired water and sewage service assets in this municipality through the transfer of 
all  related  assets  from  the  municipality  to  us.    The  amount  paid  for  the  purchase  of  assets  was  estimated  by  an 
economic-financial valuation report in approximately R$415.5 million, which included the liquidation of the water 
wholesale supply accumulated debt totaling approximately R$265.4  million.  The difference between the value of 
the assets and the accumulated debt was paid by us in cash to the municipality.  Accordingly, we started providing 
water and sewage services to the municipality of São Bernardo do Campo beginning in January 2004.   

Execution of Sewage Services Agreements with Municipalities 

We provide wholesale sewage services to the municipalities of Mogi das Cruzes, Santo André, São Caetano e Mauá.  
The  negotiation  of  the  agreement  for  the  provision  of  wholesale  sewage  services  with  the  municipality  of  Santo 
André  had  the  intervention  of  the  Public  Prosecution  Service,  and  in  other  municipalities,  it  was  a  result  of  our 
efforts concerning the environment and the awareness of the municipal public authorities related to environmental 
issues.    Through  these  agreements,  we  started  treating  about  2.2  million  cubic  meters  of  sewage  per  month  from 
these municipalities.  This is an example of our social-environmental responsibility and commitment.  In 2006, the 
revenues from these services were approximately R$1.9 million. 

Description of Our Activities 

We plan, execute, operate and market basic sanitation services and their connected benefits throughout the territory 
of the State of São Paulo. 

Water Operations 

Our  supply  of  water  to  our  customers  generally  involves  abstraction  of  water  from  various  sources,  subsequent 
treatment  and  distribution  to  customers’  premises.    In  2006,  we  produced  approximately  2,886.8  million  cubic 
meters  of  water.    The  São  Paulo  Metropolitan  Region  currently  is,  and  has  historically  been,  our  core  market, 
accounting for approximately 72% of water invoiced by volume in 2006. 

The following table sets forth the volume of water that we produced and invoiced for the periods indicated.

The difference between the volume of water produced and the volume of water invoiced generally represents both 
physical  and  non-physical  water  loss.    See  “—Water  Resources—Water  Distribution.”    In  addition,  we  do  not 
invoice: 

• 

• 

water discharged for periodic maintenance of water mains and water storage tanks; 

water supplied for municipal uses such as firefighting; 

29 

 
 
 
 
 
 
 
 
• 

• 

water consumed in our own facilities; and 

estimated water losses associated with water we supply to favelas (shantytowns). 

The São Paulo Metropolitan Region experiences its highest levels of demand during the summer months when water 
use  increases.    Water  use  generally  decreases  during  the  winter  months.    The  summer  months,  when  demand  is 
highest, coincide with the rainy season, while the winter, when demand for water is lowest, corresponds to the dry 
season  in  the  São  Paulo  Metropolitan  Region.    Demand  within  the  Regional  Systems  will  vary  depending  on  the 
area; while the interior region experiences seasonality in demand similar to the São Paulo Metropolitan Region, the 
demand  in  the  coastal  region  is  chiefly  a  function  of  tourism,  with  the  greatest  demand  occurring  during  the 
Brazilian summer holiday months.

Water Resources 

We can abstract water only to the extent permitted by the State Department of Water and Energy and pursuant to 
authorization contracts entered into with it.  Under some circumstances, depending on the geographic location of the 
relevant river basin or reservoir, the approval of the National Water Agency (Agência Nacional de Águas), or ANA, 
is also required.  We currently abstract substantially all of our water supply from rivers and reservoirs, with a small 
portion being abstracted from groundwater.  Our reservoirs are filled by impounding water from rivers and streams, 
by diverting flow from nearby rivers, or by a combination of these sources. 

In order to supply water to the São Paulo Metropolitan Region, we rely on 20 reservoirs of non-treated water and 
182  reservoirs  of  treated  water,  which  are  located  in  the  areas  under  the  influence  of  the  eight  water  producing 
systems  which  comprise  the  interconnected  water  system  of  the  São  Paulo  Metropolitan  Region.    Resource 
availability, or volume of water available at the source for public distribution in these areas, is 71.7 cubic meters per 
second, due to the conclusion of the barriers of the Alto Tietê system.  Total current capacity, or volume of water 
that can be treated from the interconnected water system of the São Paulo Metropolitan Region, is 67.7 cubic meters 
per second and has been designed to reach 75.2 cubic meters per second in 2009.  Average verified production or 
volume  treated  during  2006  on  the  interconnected  water  system  of  the  São  Paulo  Metropolitan  Region  was  66.2 
cubic meters per second.  The Cantareira, Guarapiranga and Alto Tietê systems, as a whole, supply approximately 
84.1% of the water we produced for the São Paulo Metropolitan Region in 2006. 

The  Cantareira  system  accounts  for  approximately  48.7%  of  the  water  that  we  provided  to  the  São  Paulo 
Metropolitan Region (including the municipalities to which we provide water on a wholesale basis) in 2006, which 
represented 75.8 % of our operating revenue for 2006.  The authorization (outorga) for the Cantareira system to use 
the water in the Piracicaba water basin was renewed on August 6, 2004 for a period of ten years.  

With respect to water usage, federal and state agencies are authorized to collect charges from entities, such as us, for 
the  abstraction  of  water  from,  or  dumping  of  sewage  into,  water  recourses.    Since  February  2004  we  have  been 
incurring expenses in connection with the use of water from the Paraíba do Sul River Basin and since January 2006 
from the Piracicaba, Capivari and Jundiaí River Basin.  Our tariff readjustment formula takes into consideration the 
variation of expenses considered as “non-administrable,” which these expenses fall under.  We expect to continue to 
be able to pass on these expenses to our customers.  However, we are uncertain as to the likely charges that may be 
assessed in connection with the abstraction of water from or the dumping of sewage into other water resources that 
we use, or whether we will be able to continue to pass on the cost of all of these charges to our customers.  For more 
information on water usage regulation, see “—Water Usage.”

We own all of the reservoirs in our production systems other than the Guarapiranga  and Billings reservoirs and a 
portion  of  some  of  the  reservoirs  of  the  Alto  Tietê  system,  which  is  owned  by  other  companies  controlled  by  the 
State.    We  currently  do  not  pay  any  charges  with  respect  to  the  use  of  these  reservoirs.    In  December  2001,  we 
entered  into  an  agreement  with  the  State  whereby  the  State,  among  other  things,  agreed  to  transfer  the  remaining 
reservoirs in the Alto Tietê system to us.  However, the transfer of these reservoirs is currently being disputed and 
we  are  not  certain  whether  this  transfer  will  be  legally  allowed.    See  “Item  8.A.  Financial  Information—
Consolidated Statements and other Information——Legal Proceedings—Other Legal Proceedings.” 

In  the  largest  municipalities  of  the  interior  region,  our  principal  source  of  water  consists  of  surface  water  from 
nearby rivers.  In the smaller municipalities of the interior region, we draw water primarily from wells.  The coastal 
region is provided with water principally by surface water from rivers and mountain springs. 

Statewide, we estimate  that we are able to supply nearly all of the demand for water in all of the  areas where we 
operate, subject to droughts and extraordinary climate events.  In 2004, 2005 and 2006, we were able to  meet the 
demand for water in the São Paulo Metropolitan Region, primarily as a result of our water conservation program, 
reductions in water loss, and the installation of 907,665 new water connections from 2000 through December 2004 
and 158,323 new water connections in 2005 statewide.  In 2006, we installed 156,139 new water connections.  

The interconnected water system of the São Paulo Metropolitan Region services 30 municipalities, of which 24 are 
operated directly by us.  We serve the other six municipalities on a wholesale basis, and the distribution is made by 
other companies or departments related to the relevant municipality.   

In  order  to  reach  the  final  customer,  the  water  is  stored  and  transported  through  a  complex  and  interconnected 
system  comprising  30,535  kilometers  of  water  mains  and  182  reservoirs.    This  water  system  requires  permanent 
operational supervision, engineering inspection, maintenance, quality monitoring and measurement control. 

To ensure the continued provision of regular water supply in the São Paulo Metropolitan Region, we intend to invest 
R$1.2  million  (unaudited)  from  the  years  2007  until  2010  to  increase  our  water  production  and  distribution 
capacities as well as to improve the water supply systems.   

Water Treatment.  We treat all water at our water treatment facilities prior to placing it into our water distribution 
network.    We  operate  197  treatment  facilities,  of  which  the  eight  largest,  located  in  the  São  Paulo  Metropolitan 
Region, account for approximately 72% of all water we produce.  The type of treatment used depends on the nature 
of the source and quality of the untreated water.  Water abstracted from rivers requires extensive treatment, while 
water  drawn  from  groundwater  sources  requires  less  treatment.    All  water  treated  by  us  also  receives  fluoridation 
treatment. 

Water  Distribution.    We  distribute  through  our  own  networks  of  water  pipes  and  mains,  ranging  in  size  from  2.5 
meters to 100  millimeters in  diameter.   Storage tanks  and  pumping  stations regulate  the volume of  water  flowing 

31 

 
 
 
 
 
through the networks to  maintain adequate pressure and continuous water supply.  As of December  31, 2006, our 
water  network  contained  61,469  kilometers  of  water  pipes  and  mains  and  6.6  million  water  connections.    The 
following table sets forth the total number of kilometers of water pipes in our network for the periods indicated.

More  than  90%  of  the  water  pipes  in  our  water  distribution  network  are  made  of  cast  iron  or  polyvinylchloride 
(PVC).  Distribution pipes at customers’ residences typically are made from high-density polyethylene tubing.  Our 
water mains are mostly made of steel, cast iron or concrete. 

As of December 31, 2006, our water distribution pipes and mains included: 

• 

• 

30,535 kilometers in the São Paulo Metropolitan Region; and 

30,934 kilometers in the Regional Systems. 

We have 373 storage tanks in the São Paulo Metropolitan Region with a total capacity of 1.8 million cubic meters, 
and  1,650  storage  tanks  in  the  Regional  Systems.    We  have  122  treated  water  pumping  stations  in  the  São  Paulo 
Metropolitan Region aqueduct system, including stations at treatment facilities, intermediate trunk transfer pumping 
stations and small booster stations serving local areas.   

Water mains that require maintenance are cleaned and relined.  We are typically notified of water main fractures or 
breaks by the public through a toll-free number maintained by us.  We consider the condition of the water pipes and 
mains in the São Paulo Metropolitan Region generally to be adequate.  Due to age, external factors such as traffic, 
the  dense  population  and  commercial  and  industrial  development,  water  pipes  and  mains  in  the  São  Paulo 
Metropolitan  Region  are  somewhat  more  susceptible  to  degradation  than  those  in  the  Regional  Systems.    To 
counteract these effects, we have a maintenance program in place for water pipes and mains that is intended to deal 
with anticipated fractures and clogs due to brittleness and encrustation and to help ensure water quality. 

We  expect  that  new  customers  will  be  responsible  for  covering  part  of  the  costs  of  connecting  to  our  water 
distribution network.  Our water connection policy is to pay for the cost of installation of up to 15 meters of pipe 
from our distribution network to the point of connection, with the remainder paid by the customer.  Thereafter, the 
customer  must  cover  the  costs  of  connecting  to  the  network  from  the  customer’s  residence,  including  costs  of 
purchasing and installing the water meter and related labor costs.  Industrial customers are responsible for the entire 
cost  of  connection.    We  perform  the  installation  of  the  water  meter  and  conduct  periodical  inspections  and 
measurements.  After completion of installation, the customer is responsible for the water meter. 

The following table sets forth projected new water connections for the periods indicated.

Water Losses.  The difference between the amount of water produced and the amount of water invoiced generally 
represents  both  physical  and  non-physical  water  losses.    Water  loss  percentage  represents  the  quotient  of  (1)  the 
difference between (a) the total amount of water produced by us less (b) the total amount of water invoiced by us to 
customers minus (c) the volume of water set out below that we exclude from our calculation of water losses, divided 
by (2) the total amount of water produced by us.  We exclude the following from our calculation of water losses:  (1) 
water discharged for periodic maintenance of water mains and water storage tanks; (2) water supplied for municipal 

32 

 
 
 
 
 
 
 
uses  such  as  firefighting;  (3)  water  we  consume  in  our  facilities;  and  (4)  estimated  water  losses  associated  with 
water we supply to favelas (shantytowns). 

Since 2005, we have established a new method of measuring our water losses, based on worldwide market practice 
for  the  sector.    According  to  this  new  measurement  method,  average  water  losses  are  calculated  by  dividing  (1) 
average annual water loss by (2) the average number of active water connections multiplied by 365.  The result of 
this calculation is the liters of water lost per connection per day. 

Using  this  calculation  method,  as  of  December  31,  2006,  we  experienced  615  liters/connections  per  day  of  water 
losses in the São Paulo Metropolitan Region and 353 liters/connections per day in the Regional Systems, averaging 
511 liters/connections per day.  We plan to reduce water losses in both regions to 450 liters/connections per day for 
the São Paulo Metropolitan Region and 278 liters/connections per day for the Regional Systems, which we expect 
will result in a total reduction to 405 liters/connections per day by 2010.  Using another methodology, we intend to 
reduce  water  losses  from  32.5%  to  24%  in  the  São  Paulo  Metropolitan  Region,  and  from  30%  to  23%  in  the 
Regional Systems.  In 2006, we experienced 31.9% in water losses and we expect to decrease the water losses to 
24% in 2010.     

Our strategy to reduce water loss will be carried out by a two-step process: 

• 

• 

reduction in the level of physical losses, which result mainly from leakage, primarily through the 
replacement and repair of water mains and pipes and installation of probing and other equipment, 
including strategically located pressure-regulating valves; and 

reduction of non-physical losses, which result primarily from the inaccuracy of our water meters 
installed at our customers’ premises and at our water treatment facilities, and from clandestine and 
illegal use, through upgrading and replacing inaccurate water meters and expanding our personnel 
who work on anti-fraud actions. 

We are taking measures to decrease physical losses by reducing response times for fixing leakages to less than 24 
hours  and  by  better  monitoring  non-visible  water  mains  fractures.    Among  other  measures  we  have  adopted  to 
reduce physical water losses are: 

• 

• 

• 

• 

• 

the  introduction  of  technically  advanced  valves  to  regulate  water  pressure  throughout  the  water 
mains to correspond to downstream consumption needs each day.  These valves are programmed 
to  respond  automatically  to  variations  in  demand.    During  peak  usage,  the  flow  of  water  in  the 
pipes  is  at  its  highest  point;  however,  when  demand  decreases,  pressure  builds  up  in  the  water 
mains and the resulting stress on the network can cause significant water loss through cracks and 
an increase in ruptures of the pipes.  The intelligent valves are equipped with probes programmed 
to  feed  data  to  the  valve  to  reduce  or  increase  pressure  to  the  water  mains  as  water  usage 
fluctuates.    As  of  December  31,  2006,  we  had  installed  1,481  valves  at  strategic  points  in  the 
network, with 900 valves installed in the São Paulo Metropolitan Region and 581 in the Regional 
Systems.  We plan to install 168 additional valves through the end of 2007;  

the reconfiguration of interconnected water distribution to permit the distribution of water at lower 
pressure; 

the  implementation  of  routine  operational  leak  detection  surveys  in  high  water  pressure  areas  in 
each case helping to reduce overall water losses; 

the monitoring of and improved accounting with respect to water connections, especially for large 
volume  customers,  regular  checking  on  inactive  customers  and  monitoring  non-residential 
customers that are accounted for as residential customers and, therefore, are billed at a lower rate; 

fighting of fraud with the use of new, more sophisticated water meters that are more accurate and 
less prone to tampering; 

33 

 
 
• 

• 

installation of water meters where none are present; and 

preventive maintenance of existing and newly installed water meters. 

Water  Quality.    We  believe  that  we  supply  high  quality  treated  water  that  is  consistent  with  standards  set  by 
Brazilian law, which requirements are similar to the standards set in the United States and Europe.  Under a Health 
Ministry (Ministério da Saúde) regulation in Brazil, we have significant statutory obligations regarding the quality 
of treated water.  These laws set certain standards that govern water quality.   

In  general,  the  State  of  São  Paulo  has  excellent  quality  water  from  underground  or  superficial  water  sources.  
However, urbanization and disorganized occupation of some areas of the São Paulo Metropolitan Region ended up 
reducing the quantity of water in mains in the southern area of the São Paulo Metropolitan Region and in the coastal 
region.  Currently, we successfully treat this water to make it potable.  We also work to recover the quality of water 
of mains and invest in improvements of our treatment systems to guarantee the quality and availability of water in 
the next years. 

Water quality is monitored in all stages of the distribution process, including at the water sources, water treatment 
facilities and on the distribution network.  We have 15 regional laboratories, one central laboratory, and laboratories 
located in all water treatment facilities that monitor water quality and purity as required by standards set by us and 
as  required  by  law,  which  employ  approximately  300  technicians,  biologists,  engineers  and  chemists.    Our 
laboratories  perform an  average  of 130,000  analyses  per  month on  distributed  water,  with samples  collected  from 
residences.   Our  central  laboratory located  in the City  of  São  Paulo  is responsible  for  organic compound analysis 
using  the  chromatographic  and  spectrometric  methods,  as  well  as  heavy  metals  analysis  by  atomic  absorption 
technique.    All  of  our  laboratories  have  obtained  ISO  9001/2000  certification  and  three  of  the  Regional  Systems 
laboratories  have  obtained  a  ISO  17025  certification  awarded  by  INMETRO  with  respect  to  the  quality  of  our 
management systems and the technical ability of our laboratories to produce results.  Until 2008 we expect that all of 
water and sewage quality control laboratories will have been granted the ISO 17025 certification. 

All  chemical  products  used  for  water  treatment  are  analyzed  and  follow  strict  specifications  set  out  in 
recommendations made by the National Sanitation Foundation, or NSF, and the Brazilian Association of Technical 
Rules  (Associação  Brasileira  de  Normas  Técnicas),  or  ABNT,  to  eliminate  toxic  substances  that  are  harmful  to 
human health. 

Water  Source  Program.    From  time  to  time,  we  face  problems  with  the  proliferation  of  algae,  which  may  cause 
water to have an unpleasant taste and odor.  In order to mitigate this problem, we work on two fronts: (1) fighting 
algae growth at the water resource, resulting in our detection of no significant algae growth in 2006, and (2) using 
advanced treatment processes at the water treatment facilities, which involves the use of powdered activated carbon 
and  oxidation  by  potassium  permanganate.    The  algae  growth  creates  significant  additional  costs  because  of  the 
higher volumes of chemicals used to treat the raw water. 

We  are  planning  to  participate  in  the  Water  Source  Program  (Programa  Mananciais)  together  with  other 
organizations engaged in the promotion of urban development and social inclusion to mitigate the pollution problem 
in all systems of the São Paulo Metropolitan Region.  In this program, we will be responsible for the expansion of 
sewage systems, pre-treatment of streams and development of more sophisticated treatment facilities.  It is expected 
that the execution of this program will initiate in the first semester of 2008 financed by the International Bank for 
Reconstruction  and  Development,  or  World  Bank.    In  addition,  we  also  participate  in  the  Clean-up  Program  of 
Streams  in  the  City  of  São  Paulo  (Programa  de  Despoluição  dos  Córregos  do  Município  de  São  Paulo),  a  joint 
program with the City of São Paulo to clean up 42 important streams in this region. 

We  believe  that  there  are  no  material  instances  where  our  standards  are  not  being  met.    However,  we  cannot  be 
certain that future breaches of these standards will not occur. 

Fluoridation.    As  required  by  Brazilian  law,  we  have  adopted  a  water  fluoridation  program  which  is  designed  to 
assist in the prevention of tooth decay among the population.  Fluoridation primarily consists of adding fluorosilicic 

34 

 
 
acid to water at 0.7 parts per million.  We add fluoride to the water at our treatment facilities prior to its distribution 
into the water supply network. 

Sewage Operations 

We  are  responsible  for  the  collection  and  removal  of  sewage  through  our  sewage  systems  and  for  its  subsequent 
disposal with or without prior treatment.  As of December 31, 2006, we collected approximately 82% and 71% of all 
the  sewage  produced  in  the  municipalities  in  which  we  operate  in  the  São  Paulo  Metropolitan  Region  and  the 
Regional Systems, respectively, accounting for approximately 78% of all the sewage produced in the municipalities 
in which we operated in the State of São Paulo during 2006.   

Sewage  System.    The  function  of  our  sewage  system  is  to  collect,  remove  and  dispose  of  sewage.    As  of 
December 31, 2006, we were responsible for the operation and maintenance of 39,126 kilometers of sewer lines, of 
which approximately 19,845 kilometers are located in the São Paulo Metropolitan Region and 19,281 kilometers are 
located in the Regional Systems. 

The  following  table  sets  forth  the  total  number  of  kilometers  of  sewer  lines  and  the  total  number  of  sewage 
connections in our network for the periods indicated.

Our sewage system comprises a number of systems built at different times and constructed primarily from clay pipes 
and,  more recently, PVC tubing.  Sewage lines larger than 0.5 meters in diameter are primarily made of concrete.  
Our sewage system is generally designed to operate by gravitational flow, although pumping stations are required in 
certain parts of the system to ensure the continuous flow of sewage.  Where pumping stations are required, we use 
sewer lines made of cast iron. 

Industrial  sewage  can  vary  in  nature  and  concentration  of  contaminants.    The  standards  for  disposal  of  industrial 
effluents  are  set  forth  in  Article  19A  of  State  Decree  No.  8,468,  of  September  8,  1976,  as  amended,  and  broadly 
correspond to the standards for such disposal set by the U.S. Environmental Protection Agency.  The basic premise 
of  these  standards  is  that  industrial  effluents  interfere  with  the  natural  biological  process  at  sewage  treatment 
facilities and, therefore, the effluents must be treated so that the final effluent meets the parameters set forth in State 
Decree  No.  8,468.    This  decree  requires  industries  that  produce  industrial  sewage  to  pre-treat  the  sewage  so  that 
levels  of  certain  parameters,  such  as  pH,  temperature,  sediments,  grease,  oil  and  metals,  are  reduced  to 
environmentally  sound  levels  prior  to  release  into  our  sewer  lines.    To  ensure  compliance  with  Article  19A,  we 
periodically analyze sewage produced by each industrial customer to check whether the customer has complied with 
the requirements of the decree.  Although we may take certain actions which include imposing penalties or cutting a 
customer’s connection in the event that customer is continuously not in compliance, we are not responsible for and 
are not obligated to ensure the compliance of our customers with the requirements of this decree. 

Effluents  from  our  sewage  treatment  facilities  (Estações  de  Tratamento  de  Esgotos—ETEs)  must  comply  with 
discharge standards established by federal  and state regulations.  Flow standards are related to the composition of 
effluents  before  being  discharged  into  water  bodies,  while  quality  standards  measure  the  condition  of  the  water 
bodies after the dilution of effluents.  Both flow and quality standards will vary according to the expected use of the 
relevant body of water:  the more important the use of the body of water, the more stringent the standards applicable. 

We consider the condition of the sewer lines in the São Paulo Metropolitan Region generally to be adequate.  Due to 
greater  volume  of  sewage  collected  and  to  higher  population  and  commercial  and  industrial  development,  the 
condition  of  the  sewer  lines  in  the  São  Paulo  Metropolitan  Region  is  somewhat  worse  than  that  of  the  Regional 
Systems.  To counteract the effects of deterioration, we maintain a continuing program for the maintenance of sewer 
lines intended to deal with anticipated fractures arising from obstructions caused by system overloads. 

35 

 
 
 
 
Unlike  the  São  Paulo  Metropolitan  Region,  the  interior  region  does  not  generally  suffer  obstructions  caused  by 
sewage system overload.  The coastal region, however, experiences obstructions in its sewer lines primarily due to 
infiltration  of  sand, especially during  the  rainy  season  in  the  summer months.  In addition, the number of sewage 
connections in the coastal region is significantly lower than in the other regions served by us, with approximately 
51% of all residences in the coastal region currently connected to our sewage network. 

New sewage connections are made on substantially the same basis as connections to water lines:  we assume the cost 
of  installation  for  the  first  15  meters  of  sewer  lines  from  the  sewage  network  to  residential  and  commercial 
customers’  sewage  connections  and  the  customer  is  responsible  for  the  remaining  costs.    Industrial  customers  are 
responsible for the entire cost of extension and connection to the sewage network. 

The following table sets forth projected new sewage connections for the periods indicated.

Sewage Treatment and Disposal.  In 2006, approximately 58% and 73% of the sewage we collected in the São Paulo 
Metropolitan Region and the Regional Systems respectively, or 63% of the sewage we collected in the State of São 
Paulo, was treated at our treatment  facilities and afterwards discharged into receiving  water bodies such as inland 
waters  and  the  Atlantic  Ocean,  in  accordance  with  applicable  legislation.    Our  sewage  treatment  facilities  have  a 
finite capacity.  Flows in excess of this capacity are discharged directly, untreated, to inland waters and the Atlantic 
Ocean.  Currently we operate 438 sewage treatment facilities and eight ocean outfalls.   

The purpose of sewage treatment is to reduce the polluting impact of the incoming sewage in order to comply with 
State Decree No. 8,468, and the Resolution No. 357/05 of the Brazilian National Environment Committee (Conselho 
Nacional do Meio Ambiente), or CONAMA, which stipulates maximum concentrations of certain substances prior to 
discharge  into  the  environment.    Although  the  flow  and  composition  of  sewage  arriving  at  sewage  treatment 
facilities  varies,  on  average  more  than  98%  of  its  content  is  water.    Our  sewage  treatment  relies  essentially  on 
physical  separation  processes  and  on  natural  biological  processes  to  break  down  organic  matter  and  reduce  the 
amount of harmful organisms and chemicals. 

The  primary  treatment  process  is  the  principal  separation  process  for  suspended  solid  material  present  in  raw 
sewage.  The sewage is passed into sedimentation tanks.  Solid matter settles to the bottom of the tanks, is removed 
as sludge and is then passed to the sludge treatment process.  The sewage remaining after this sedimentation process 
is either given activated sludge treatment or may be discharged to receiving waters. 

The activated sludge treatment process, the principal method for secondary treatment of sewage used by us, relies on 
natural bacterial action to break down the organic matter in sewage and, where required, to remove ammonia.  In the 
activated  sludge  treatment  process,  the  sewage  from  primary  treatment  is  passed  into  aeration  tanks  that  are 
continuously  replenished  with  re-circulated  activated  sludge.    The  mixture  in  the  tanks  is  agitated  and  aerated, 
enabling the micro-organisms in the activated sludge to digest organic material contained in the incoming sewage.  
The effluent and activated sludge mixture produced by this process flows over to the final sedimentation stage. 

We operate 44 activated sewage treatment facilities, each of which also contains a primary treatment facility.  The 
five  largest  activated  sewage  treatment  facilities  located  in  the  São  Paulo  Metropolitan  Region  have  treatment 
capacity of approximately 18 cubic meters of sewage per second.   

Sewage  treatment  in  the  Regional  Systems  will  vary  according  to  the  particularities  of  each  area.    In  the  interior 
region,  treatment  consists  largely  of  stabilization  ponds  where  the  organic  matter  is  treated  and  discharged  to 
receiving waters.  There are 354 secondary treatment facilities in the interior region which have treatment capacity 
of approximately 9.7 cubic meters of sewage per second.   

36 

 
 
 
 
 
 
The  majority  of  sewage  collected  in  the  coastal  region  receives  treatment  and  disinfection  and  is  then  discharged 
into rivers and into the Atlantic Ocean.  We have 66 sewage treatment facilities in the coastal region.   

Our  trunk  lines  are  currently  not  sufficiently  extensive  to  transport  all  sewage  collected  by  us  to  our  treatment 
facilities.  As a result, a portion of the sewage collected by us is released untreated into receiving waters, resulting in 
high  levels  of  pollution  in  these  bodies  of  water.    We  are  a  party  to  a  number  of  legal  proceedings  related  to 
environmental matters.  See “Item 8.A. Financial Information—Consolidated Statements and other Information——
Legal  Proceedings.”    In  addition,  our  capital  expenditure  program  includes  projects  to  increase  the  amount  of 
sewage

Requirements.” 

that  we 

treat. 

Sludge Disposal.  Sludge removed from the primary and secondary treatment processes typically contains water and 
a  very  small  proportion  of  solids.    We  use  filter  presses,  belt  presses  and  centrifugation  machines  to  abstract  the 
water from the sludge.  In 2006, we produced approximately 53,789 tons of sludge-dry base, of which 49,387 tons 
were discharged into landfills and the remainder was used for agricultural purposes.  In addition, we are testing new 
technologies for sludge disposal as fertilizer in forest projects, fuel development and concrete manufacturing. 

Customers 

We  currently  operate  water  and  sewage  systems  in  367  of  the  645  municipalities  in  the  State  of  São  Paulo.    In 
addition, we currently sell water on a wholesale bases to six municipalities with a total population of approximately 
3.2  million.    The  following  table  provides  a  breakdown  of  total  revenues  by  geographic  market  for  the  periods 
indicated.

Competition 

We believe there are at least two reasons behind a possible increase in our participation in the domestic sanitation 
market.  There are 273 municipalities in the State of São Paulo that operate their own water and sewage systems and 
that  collectively  have  a  population  of  approximately  12.4  million,  or  approximately  30%  of  the  population  of  the 
State  of  São  Paulo,  excluding  the  population  of  the  municipalities  to  which  we  provide  water  services  on  a 
wholesale basis.  In addition, there are private water companies which provide water and sewage services to a small 
number of municipalities in the State of São Paulo, which may indicate a potential opportunity for the increase of 
our market share. 

In  general, we do not  face  any competition  in  the  municipalities in  which we provide water  and sewage services.  
However,  governments  of  these  municipalities  may  also  compete  with  us,  if  they  resume  the  water  and  sewage 
services that were granted to us and start providing these services directly to the local population.  In this case, the 
municipal governments would be required to indemnify us for the unamortized portion of our investment.  See “—
Our  Operations—Concessions.”    In  the  past,  municipal  governments  have  terminated  our  concessions  contracts 
before the expiration date.  Also, municipal governments have tried to expropriate our assets in an attempt to resume 
the  provision  of  water  and  sewage  services  to  local  populations.    See  “Item  8.A.  Financial  Information—
Consolidated  Statements  and other  Information—Legal  Proceedings.”   We  negotiate  expired  concession contracts 
and  concession  contracts  to  be  expired  with  the  municipalities  in  an  attempt  to  maintain  our  existing  areas  of 
operations. 

37 

 
 
 
 
 
 
 
 
We  face  a  limited  level  of  competition  with  respect  to  the  supply  of  water  to  large  customers.    Several  large 
industrial  customers  located  in  municipalities  served  by  us  use  their  own  wells  to  supply  themselves  with  water.  
This  use  of  private  wells  has  been  increasing  in  recent  years.    We  have  established  new  tariff  schedules  for 
commercial  and  industrial  customers  in  order  to  help  retain  these  customers.    Additionally,  we  already  face 
competition  for  the  disposal  of  non-residential,  commercial  and  industrial  sludge  in  the  São  Paulo  Metropolitan 
Region.  

Billing Procedures 

The  procedure  for  billing  and  payment  of  our  water  and  sewage  services  is  basically  the  same  for  each  customer 
category.  Water and sewage bills are based upon water usage determined by monthly water meter readings.  Larger 
customers, however, have their meters read every 15 days to avoid non-physical losses resulting from faulty water 
meters.  Sewage billing is included as part of the water bill and is based on the water meter reading. 

We deliver all water and sewage bills by hand to our customers,  mainly through independent contractors who are 
also responsible for reading water meters. 

Water and sewage bills can be paid at some banks and other locations in the State of São Paulo.  These funds are 
paid  over  to  us  and  average  service  fees  between  R$0.32  (unaudited)  and  R$1.15  (unaudited)  per  transaction  are 
charged for collection and remittance of these payments.   

Customers must pay their water and sewage bills by the due date if they wish to avoid paying a fine.  We generally 
charge a penalty fee and interest on late bill payments.  In 2004, 2005 and 2006, we received, respectively, payment 
of  94.1%,  90.8%  and  91.5%  of  the  amount  billed  to  our  retail  customers,  and  94.4%,  91.1%  and  92.5%  of  the 
amount  billed  to  those  customers  other  than  State  entities,  within  30  days  after  the  due  date.    With  respect  to 
wholesale  sales,  in  2005  and  2006,  we  received  payment  of  60.6%  and  61.4%,  respectively,  of  the  amount  billed 
within 30 days. 

In  the  São  Paulo  Metropolitan  Region,  we  monitor  water  meter  readings  by  use  of  hand-held  computers  and 
transmitters.    The  system  allows  the  meter  reader  to  input  the  gauge  levels  on  the  meters  into  the  computer  and 
automatically  print  the  bill  for  the  customer.    The  hand-held  computer  tracks  water  consumption  usage  at  each 
metered location and prepares bills based on actual meter readings.  We outsourced this billing system to third-party 
contractors  that  employ  and  train  their  own  meter  readers  whose  training  we  supervise.    We  have  water  meter 
reading  and  printing  by  hand-held  computers  in  some  municipalities  that  we  serve  in  the  Regional  Systems  and 
intend to expand this system in other municipalities we serve. 

Tariffs 

The  new  basic  sanitation  law,  Law  No.  11,445,  does  not  affect  the  terms  and  conditions  with  respect  to  tariff 
adjustments under our existing concessions.  Contracts that are currently in effect will be adjusted according to the 
formula  that  we  have  applied  to  them.    Pursuant  to  Law  No.  11,445,  as  a  general  rule,  the  new  state  regulatory 
authority that will  be created and replace the Commission for the Regulation of Sanitation Service of the State of 
São  Paulo  (Comissão  para  a  Regulação  dos  Serviços  de  Saneamento  Básico  do  Estado  de  São  Paulo),  or 
CORSANPA, will be responsible for setting and adjusting tariffs.  While the new state regulatory authority is not 
created,  the  Sanitation  and  Energy  Secretariat  of  the  State  of  São  Paulo  will  be  temporarily  in  charge  of  these 
responsibilities.   

Until the definition of the entity responsible for establishing tariffs regulations, we intend to continue adjusting our 
tariffs for water and sewage services according to the formula we current1y use, which covers our operating costs 
and other expenses, accounts for inflation, and provides for return on investment.  To ensure proper adjustment of 
our tariffs and higher return on investment, we intend to restructure our tariffs with values based on costs of services 
for all segments or clients, except for the low-income population, which should be subsidized. 

38 

 
 
Tariffs have historically been adjusted once a year and for periods of at least 12 months.  We raised tariffs in June 
2001, in July 2002 and in August 2003.  We increased our tariffs for water and sewage services by 6.8% on August 
29, 2004 and by 9.0% on August 31, 2005.  On August 31, 2006, we increased our tariffs by 6.71%. 

Although we have the power to set our tariffs for water and sewage services, the State of São Paulo, our controlling 
shareholder, through its ownership of our common shares and control of our board of directors, may interfere in our 
tariff  adjustment.    For  example,  we  did  not  increase  tariffs  in  2000  due  to  a  State  policy  for  the  year  of  not 
increasing tariff rates for some public carriers, such as public transportation and water supply services. 

We established a new tariff schedule, effective May 2002, for commercial and industrial customers that consume at 
least  5,000  cubic  meters  of  water  per  month  and  that  enter  into  demand  agreements  with  us  for  at  least  one-year 
terms.  We believe this tariff schedule will help prevent our commercial and industrial customers from switching to 
the use of private wells. 

On  August  29,  2003,  we  developed  and  implemented  a  new  readjustment  formula  for  our  tariffs  to  better  reflect 
changes  in  our  cost  structure.    According  to  this  new  formula,  the  cost  components  of  the  Tariffs  Readjustment 
Index, or IRT, are separated into two parts (“Part A” and “Part B”), where “Part A” encompasses all costs related to 
energy, to water and sewage treatment materials, to federal, state and local taxes, and to financial compensation due 
to use of water resources; and where “Part B” encompasses all other costs and expenses.  The readjustment of “Part 
A” is based on the price variation observed in its components during the preceding 12-month period.   “Part B” is 
adjusted by the IPCA index. 

We establish separate tariff schedules for our services in each of the São Paulo Metropolitan Region and each of the 
interior and coastal regions which comprise our Regional Systems.  Each tariff schedule incorporates regional cross-
subsidies, taking into account the customers’ type and volume of consumption.  Tariffs paid by customers with high 
monthly water consumption rates are higher tariffs than our costs of providing the water service.  We use the excess 
tariff billed to high-volume customers to compensate for the lower tariffs paid by low-volume customers.  Similarly, 
tariffs  for  non-residential  customers are established at levels that  subsidize  residential customers.   In  addition, the 
tariffs for the São Paulo Metropolitan Region generally are higher than tariffs in the interior and coastal regions. 

We divide tariffs  into two categories:  residential and non-residential.  The residential category is subdivided into 
standard  residential,  social  and  favela  (shantytowns).    The  residential  social  tariffs  apply  to  residences  of  low-
income families, residences of persons unemployed for up to 12 months and collective living residences.  The favela 
tariffs  apply  to  residences  in  shantytowns  characterized  by  a  lack  of  urban  infrastructure.  The  latter  two  sub-
categories were instituted to assist lower-income customers by providing lower tariffs for consumption.  The non-
residential category consists of: 

• 

• 

• 

commercial, industrial and public customers; 

“not-for-profit” entities that pay 50% of the prevailing non-residential tariff; and 

government entities that have entered into a water loss reduction agreement with us and pay 75% 
of the prevailing non-residential tariff. 

Sewage  charges  in  each  region  are  fixed  and  are  based  on  the  same  volume  of  water  charged.    In  the  São  Paulo 
Metropolitan Region and the coastal region, the sewage tariffs equal the water tariffs.  In the interior region, sewage 
tariffs  are  approximately  20%  lower  than  water  tariffs.    Wholesale  water  rates  are  the  same  for  all  municipalities 
served.    We  also  make  available  sewage  treatment  services  to  those  municipalities  in  line  with  the  applicable 
contracts and tariffs.  In addition, various industrial customers pay an additional sewage charge, depending on the 
characteristics of the sewage they produce. 

Each category and class of customer pays tariffs according to the volume of water consumed.  The tariff paid by a 
certain  category  and  class  of  customer  increases  progressively  according  to  the  increase  in  the  volume  of  water 
consumed.  The following table sets forth the water and sewage services tariffs by (1) customer category and class 

39 

 
 
and (2) volume of water consumed charged during the years and period stated in the São Paulo Metropolitan Region, 
which accounted for approximately 75.8% of our gross revenue from sales and services in 2006.

In 2006, the average tariff calculated for the Regional Systems was 30% below the average tariff of the São Paulo 
Metropolitan Region. 

During mid-1999 until mid-2001, we did not raise our tariffs, due to a State policy of not increasing tariffs for some 
public services.  In June 2001, we increased our average tariffs by approximately 13.1%, which was broadly in line 
with  the  prevailing  inflation  rates  in  Brazil  since  mid-1999,  and  in  August  2002  we  raised  our  tariffs  by 
approximately  8.2%.    Using  a  new  readjustment  formula  approved  by  our  board  of  directors,  in  August  2003  we

raised our tariffs for water and sewage services by approximately 18.9%, and in August 2004 we raised our tariffs 
for water and sewage services by approximately 6.8%.  

The  application  of  the  formula  in  2005  would  result  in  a  tariff  increase  of  11.12%,  part  of  which  increase  is 
attributable  to  the  increase  in  the  federal  taxes.    Because  this  increase  was  much  higher  than  the  accumulated 
inflation levels for the corresponding period, we decided to adjust the tariff by 9%, effective August 31, 2005.  The 
remaining percentage (1.94%) was deferred to the 2006 tariff adjustment.  On August 31, 2006, we increased our 
tariffs by 6.71%.  In 2004, we initiated certain studies for the restructuring of our tariffs.  These studies include a 
study of our costs, taking into account economic efficiency, future costs of operation and payment capacity of low-
income families.  We have also prepared a marketing strategy for the segmentation of our clients and of the market, 
taking into consideration specific characteristics and commercial potential as well as proposals for improvement of 
our tariff policies. 

We concluded a study on this topic in January 2006 and our board of executive officers created a team to evaluate 
and,  if  needed,  to  update  and  report  the  actions  necessary  for  the  implementation  of  the  recommendations  of  the 
study.  To date, we have not defined the term for these actions and we believe, based on our advisors’ opinion, that 
we  will  implement  the  recommendations  of  the  study  within  four  years.  See  “—Government  Regulation—Tariff 
Regulation of São Paulo” for additional information regarding our tariffs. 

Energy Consumption 

The use of energy is material to our operations, and as a result we are one of the largest users of energy in the State 
of São Paulo, which represents 1,9% of the total energy consumption in the State of São Paulo.  We obtain energy 
primarily from Companhia Energética São Paulo, or CESP, pursuant to a long-term contract expiring in 2012.  To 
date, we have not experienced any major disruptions in energy supply.  Any significant disruption of energy to us 
could have a material adverse effect on our business, financial condition, results of operations or prospects. 

Energy  prices  have  a  significant  impact  on  our  results  of  operations.    An  average  increase  of  17.5%  in  2004 
negatively  affected  our  results  of  operations.    In  2005,  we  migrated  43%  of  our  energy  requirements  to  the  “free 
market” where we can more efficiently negotiate the supply of energy and improve energy efficiency.  See “Item 5. 
Operating and Financial Review and Prospects.” 

Insurance 

We  maintain  insurance  covering,  among  other  things,  fire  or  other  damage  to  our  property,  office  buildings  and 
third-party  liability.    We  also  maintain  insurance  coverage  for  directors’  and  officers’  liability  (D&O  insurance).  
We currently obtain our insurance policies through public bids involving major Brazilian and international insurance 
companies  in  Brazil.    As  of  December  31,  2006,  we  had  paid  a  total  aggregate  amount  of  R$4.78  million  in 
premiums, covering approximately R$667.5 million on assets, third-party liabilities and D&O insurance.  We do not 
have insurance coverage for business interruption risk because we do not believe that the high premiums for such 
insurance  are  justified  by  the  low  risk  of  major  interruption.    In  addition,  we  do  not  have  insurance  coverage  for 
liabilities arising from water contamination or other problems involving our water supply to customers.  We believe 
that we maintain insurance at levels customary in Brazil for the type of business in which we are engaged. 

Environmental Matters 

Our  water  and  sewage  operations  are  subject  to  stringent  Brazilian  federal,  state  and  local  laws  and  regulations 
relating to the prevention and control of the environment’s pollution. 

In  the  State  of  São  Paulo,  the  Environmental  Sanitation  Technology  Company  (Companhia  de  Tecnologia  de 
Saneamento Ambiental), or CETESB, is the governmental agency in charge of the control, supervision and licensing 
of  the activities that  generate  pollution,  pursuant to State Law  No. 997,  dated May 31,  1976,  which sets  forth the 
control of the environment’s pollution.  In particular, the construction and operation of water and sewage treatment 

41 

 
 
 
facilities, as well as the release of effluents and final disposal of the sludge generated as a result of the water and 
sewage treatment processes, must comply with environmental standards established by state and federal legislation, 
such as State Decree No. 8,468, dated September 8, 1976, in addition to the provisions and amendments of the State 
Decree No. 15,425, dated July 23, 1980.  At the federal level, it is important to mention CONAMA Resolution No. 
357, dated March 17, 2005.  

Non-compliance with environmental laws and regulations can lead to the imposition of criminal and administrative 
penalties, in addition to civil liability which may arise as a result of environmental damages.  Pursuant to Federal 
Law No. 9,605, of February 12, 1998, individuals (including but not limited to the directors, officers and managers 
of  legal  entities)  may  be  penalized  with  imprisonment  or  other  restrictions  on  personal  rights  for  violations  of 
environmental rules and regulations, and legal entities may be penalized with fines, restrictions on rights, including, 
among other things, rights to be granted tax benefits and to enter into contracts with public entities, and mandatory 
rendering of services in the public benefit.  At the administrative level, penalties range from warnings and fines to 
partial  or  total  suspension  of  corporate  activities,  and  may  also  include  the  forfeiture  of,  or  restriction  on,  tax 
incentives, and the cancellation or interruption of participation in credit facilities granted by government banks, as 
well as a prohibition on contracting with entities of the public sector. 

Our procedure for constructing and operating water and sewage facilities involves the mandatory compliance with 
environmental  legal  requirements.    Firstly,  for  those  projects  which  have  a  significant  environmental  impact, 
specific  studies  denominated  Studies  of  Environmental  Impact  (Estudos  de  Impacto  Ambiental),  or  EIA.    These 
studies  are  related  to  actions  addressed  to  minimize  the  environmental  impact  of  a  project  and  are  prepared  by 
independent experts – multidisciplinar teams allocated to prepare the Report of Environmental Impact (Relatório de 
Impacto Ambiental), or RIMA, which presents various recommendations that aim at minimizing the environmental 
consequences of a project.  This report is then submitted to governmental authorities for analysis and approval, and 
is subject to a formal process denominated Evaluation of Environmental Impact (Avaliação de Impacto Ambiental), 
or AIA.  After the approval of the project, it undergoes a licensing process to assure that the preventive and control 
measures for the projects are compatible with sustainable development.  The licensing process is composed of three 
phases, which include the following licenses:   

• 

• 

• 

Previous  license  –  granted  at  the  planning  phase,  approving  the  location  and  conception  of  the 
project and attesting to its environmental responsibility.   

Installation  license  –  authorization  of  the  commencement  of  the  construction  and  installation  of 
the  project  upon  the  compliance  of  the  plans,  programs  and  projects  approved,  including  the 
enviromental control measures and other necessary technical requirements. 

Operation license – authorization for the operation of the unit or activity upon full compliance  of 
the technical requirements contained in the installation license.   

In order to obtain the environmental licensing of those undertakings that may provoke a significant environmental 
impact, environmental agencies may impose on us an obligation to establish a nature conservation area.  In order to 
fulfill this obligation, we are required by environmental regulations to spend not less than 0.5% of the total cost of 
the relevant undertaking for that purpose.  We have strongly participated in the protection of water mains to improve 
environmental conditions and preserve water resources of the São Paulo Metropolitan Region, either because of the 
execution  of  construction  projects  to  eliminate  the  disposal  of  raw  sewage  into  bodies  of  water  through  the 
collection and treatment of sewage, or indirectly through several programs of on-going environmental education at 
Sabesp  that  involve  various  sectors  of  the  society,  elementary  and  high  schools,  universities,  associations  of 
neighborhood,  not-for-profit  organizations,  among  others.    It  is  also  our  policy  to  implement  water  conservation 
programs, under several types, in order to minimize the impact of our operations on our water supply, through the 
reuse of effluents of sewage treatment facilities at the site of operation of the facility, or through stimulation of the 
rational use of water by means of specific programs with this goal.   

In the development of our funtions, we directly interact with the environment to attain our principles in order to be 
recognized for our “worldwide standard of excellence in the provision of environmental sanitation services” through 
our commitment to enviromental health, as well as to social and environmental responsibility.  Environmental issues 
are important at different levels, either because of the legislation that is becoming more restrictive, or because of the 

42 

 
 
society  that  is  becoming  more  conscious  and  participating  more  actively  in  solving  these  issues.    In  addition,  the 
market is also becoming more stringent and demanding with respect to the solution of these issues. 

We believe that sustainable development is a means of ensuring not only quality for the environment and people’s 
lives, but also long-term economic-financial sustainability.  In order to strengthen our commitment to environmental 
sustainability,  our  structure  includes  organizational  units  that  are  in  charge  of  environmental  planning  and 
management, environmental control and monitoring, environmental technique and development and water resources 
management.  In the external sphere, we plan to integrate initiatives with state and municipal agencies to work on 
recovering and preservation of water supply resources, and articulation with non-governmental organizations to run 
environmental guidance and education campaigns. 

Government Regulation 

Basic sanitation services in Brazil are subject to an extensive federal, state and local legislation and regulation that, 
among other things, regulates:

General 

Pursuant to Article 23 of the Brazilian Constitution, water and sewage services are the common responsibility of the 
Federal Government, the states and the municipalities. 

Article 216 of the Constitution of the State of São Paulo provides that, by law, the State must provide the conditions 
for efficient management and adequate expansion of water and sewage services rendered by its agencies and State-
controlled  companies  or  any  other  concessionaire  under  its  control.    State  law  authorized  our  formation  to  plan, 
provide  and  operate  water  and  sewage  services  in  the  State  and  also  acknowledged  the  autonomy  of  the 
municipalities. 

43 

 
 
 
Pursuant to Article 175 of the  Brazilian Constitution, the  furnishing of public services, such as water and sewage 
services, is the responsibility of the applicable public authority.  However, any such public authority has the right to 
furnish these services directly or through a concession granted to a third party. 

Law No. 11,107/05 (Consortium Law) and Law No. 11,445/07, the new basic sanitation law, recently enacted by the 
Brazilian  Congress,  have  caused  significant  impacts  in  the  development  of  the  state  sanitation  policy  and  the 
regulatory structuring of the industry.  

Because we are the legal concessionaire  for the State of São Paulo for water supply and sewage services, serving 
approximately  60%  of  the  State’s  population  and  providing  sanitation  services  through  concession  contracts,  we 
notice the impacts of this legislation on the expiration of our contracts in the 1970’s when the Brazilian Sanitation 
Plan (Plano Nacional de Saneamento), or PLANASA, was created. 

Law  No.  11,107/05  has  caused  important  changes  in  the  relationship  among  municipalities,  states  and  public 
sanitation  services  providers,  most  notably  mixed  capital  companies,  such  as  ourselves,  because  of  the 
implementation of the program agreements as a substitute for concession contracts. 

In  addition,  Law  No.  11,445/07  in  its  role  of  general  guideline  for  the  development  of  the  Brazilian  sanitation 
industry, addresses the conditions of validity for the delegation of water supply and sewage services, the exercise of 
ownership  by  the  granting  authority  and  the  regulatory  conditions  for  the  industry.    The  new  basic  sanitation  law 
also  provides  for  a  significant  amendment  to  Article  42  of  the  Concessions  Law  (Law  No.  8,987/95),  which 
establishes  the  termination  of  concessions  prior  to  the  due  expiration  date  and  the  reversibility  conditions  of 
unamortized  assets.    The  amendment  requires  that  the  service  provider  be  compensated  for  unamortized  assets, 
prioritizing an agreement between the parties setting out the criteria for calculation and payments of indemnity.  

The Basic Sanitation Law 

On January 8, 2007, Law No. 11,445 was enacted and it establishes nationwide guidelines for basic sanitation and 
seeks  to  create  solutions  that  are  adequate  for  the  reality  of  each  state  and  municipality,  facilitating  the  technical 
cooperation between the state and municipalities.  In addition, the Federal Government will enact its public policy to 
facilitate access to financing alternatives that are compatible with the costs and terms of the sanitation industry, in 
substitution of the PLANASA model. 

Law No. 11,445 establishes the following principles for basic sanitation public services: universalization, integrality, 
efficiency and economic sustainability, transparency of actions, social control and integration of infrastructure and 
services with the management of water resources.  

This  law  does  not  define  the  ownership  of  the  sanitation  services,  but  establishes  the  minimum  liability  for  the 
exercise  of  ownership,  such  as  the  development  of  the  sanitation  plan,  definition  of  the  person  responsible  for 
regulation and control, establishment of the rights and obligations of the users and of the social control mechanisms. 
It also defines the regionalized performance of the services (i.e., one single provider serves two or more owners, for 
which there may be one plan for the combination of services). 

In addition, the new basic sanitation law defines the guidelines and objectives of the federal basic sanitation policy 
to be observed when securing public funds generated or operated by agencies or entities of the Federal Government, 
and foresees the possibility of having subsidies as an instrument of social policy to ensure access to basic sanitation 
services to everyone, particularly the low-income population. The subsidies may be granted either directly, through 
tariffs or internal, depending on the characteristics of the beneficiaries and on the source of the funds. 

Furthermore,  the  law  also  provides  that  the  sanitation  services  may  be  interrupted  by  the  service  provider,  in  the 
event  of  default  of  payment  of  the  tariffs  by  the  customer,  among  other  reasons,  after  written  notice,  as  long  as 
minimum health requirements are met. 

Finally, the legislation establishes the criteria for the reversal of assets at the time of termination of the agreement 
and with regard to the concessions, such as those that have expired or are effective for an indefinite term, or those 

44 

 
 
 
 
 
 
 
 
 
 
 
that were not formalized by an agreement.  In adittion, the law provides the calculation and value of the indeminity 
that must be calculated by a specialized institution chosen by mutual agreement between the parties. 

In  the  absence  of  mutual  agreement,  the  calculation  of  the  indemnity  is  based  on  the  terms  and  conditions  of  the 
previous  agreement,  or  in  the  absence  thereof,  upon  economic  valuations  or  book  value  revaluation  of  the 
investment.    It  should  also  be  calculated  by  a  specialized  institution  chosen  by  mutual  agreement  between  the 
parties. 

Payment is to be effected in up to four, equal and successive, annual installments, with a guarantee, being the first 
payment payable by no later than the end of the financial year in which the reversal occurs.  

Concessions 

Concessions for providing water and sewage services are formalized by agreements executed between the state or 
municipality, as the case  may be, and a concessionaire to which the performance of these services is granted  in  a 
given municipality or region.  Our concessions normally have a contractual term of up to 30 years, although some of 
our concessions have an indefinite term of effectiveness. However, our concessions in general can be revoked at any 
time if certain standards of quality and safety are not met, or in the event of default of the terms of the concession 
contract.  

A  municipality  that  chooses  to  assume  the  control  of  its  water  and  sewage  services  must  terminate  the  current 
relationship  by  means  of  evaluation  of  the  value  of  the  investments  to  compensate  the  service  provider.  
Subsequently, the municipality will be in charge of rendering services or of conducting a public bidding process to 
grant the concession to potential concessionaires, including agreements with public companies directly.  Although 
the  Constitution  of  the  State  of  São  Paulo  determines  that  the  relevant  municipality  would  have  to  pay  us  for  the 
unamortized book value of the assets related to the concession and assume any correlated debt, with the exclusion of 
any amounts that have been paid to us by the municipality, upon termination or non-renewal of the concession, the 
payment  for  termination  may  not  be  effected  immediately,  and  any  termination  could  negatively  affect  our  cash 
flows, operating results and financial situation. 

The  Federal  Concessions  Law  and  the  State  Concessions  Law  require  that  the  granting  of  a  concession  by  the 
government  be  preceded  by  a  public  bidding  process.  However,  the  Federal  Public  Bidding  Law  provides  that  a 
public bidding process can be waived in certain circumstances, including in the case of services to be provided by a 
public  entity  created  for  such  specific  purpose  on  a  date  prior  to  the  effectiveness  of  this  law,  provided  that  the 
contracted  price  is  compatible  with  what  is  practiced  in  the  market.  Furthermore,  a  provision  of  the  Federal 
Constitution determines waiver of the public bidding requirement in similar situations. Based on this provision, the 
municipalities granted concessions with waiver of public bidding processes to us after the enactment of the Federal 
Constitution.    Currently,  the  new  basic  sanitation  law  provides  that  the  program  agreement  can  be  executed  with 
waiver of a public bidding process. 

Municipal  Law  No.  13,670,  dated  November  25,  2003,  created  the  Municipal  System  for  Regulation  of  Water 
Supply and Sanitary Sewage Services (Sistema Municipal de Regulação dos Serviços de Abastecimento de Água e 
Esgotamento  Sanitário),  providing  for  their  constitution  and  operation  and  also  establishing  the  Municipal 
Sanitation Plan (Plano Municipal de Saneamento). According to this Law, the Mayor of the City of São Paulo has 
powers to grant and monitor formal concessions for water and sewage services in the City of São Paulo. Subsequent 
to Law No. 13,670, the Governor of the State filed a legal action claiming that this law was unconstitutional and, as 
a consequence, the applicability of Law No. 13,670 was suspended.  On April 20, 2005 the court ruled, by majority 
of votes, in favor of the Governor of the State. The City of São Paulo appealed the decision and a final decision is 
still pending to this date. 

Public Consortia Law 

On  April  6,  2005,  the Federal Government  enacted Law  No. 11,107,  which  regulates  Article 241 of  the Brazilian 
Constitution.    This  new  regulation  provides  general  principles  to  be  observed  when  public  consortia  enter  into 
contracts with the Brazilian political divisions and subdivisions (the Federal Government, states, the Federal District 
and municipalities) aiming at the joint management of public services of common interests.   

45 

 
 
 
 
 
 
 
 
 
Federal  Decree  No.  6,017/07,  which  regulated  the  Public  Consortia  Law,  sets  forth  the  manner  in  which  new 
agreements will be entered into.     

On January 13, 2006, the Governor of the State of São Paulo enacted State Decree No. 50,470, which provides for 
the rendering of water and sewage services in the State of São Paulo.  According to this Decree, we may enter into 
agreements with municipalities in connection with the provision of water and sewage services by means of the so-
called program agreements.  In addition, the Decree establishes that we will continue to render services in the areas 
where the concession is granted by the State. 

Based  on  the  aforementioned  statutes,  in  January  2007  we  executed  our  first  program  agreement  with  the 
municipality of Lins, located in the State of São Paulo.   

On June 8, 2006, the State of São Paulo enacted the Decree No. 50,868 creating the Commission for the Regulation 
of  Sanitation  Service  of  the  State  of  São  Paulo  to  provide  the  State  of  São  Paulo  with  a  more  independent 
regulatory ability in relation to sanitation services.  The Commission for the Regulation of Sanitation Service of the 
State of São Paulo is directly subordinated to the Sanitation and Energy Secretariat of the State of São Paulo. 

The  Commission  for  the  Regulation  of  Sanitation  Service  of  the  State  of  São  Paulo’s  responsibilities  include, 
among  others,  (1)  the  regulation  and  inspection  of  basic  sanitation  services  under  the  State  government’s 
responsibility,  including  the  monitoring  of  the  development  of  our  performance  and  the  development  of  dispute 
resolution between Sabesp and Sabesp’s customers, (2) the approval of the agreements entered into between us and 
the  municipalities,  (3)  the  conduction  of  studies  for  the  creation  of  a  regulatory  agency  for  the  basic  sanitation 
industry and the presentation of legal and regulatory measures, if applicable. The Commission for the Regulation of 
Sanitation Service of the State of São Paulo shall also present the terms of the cooperation agreements to be entered 
into  by  the  State  government  and  the  municipalities  to  better  regulate  our  relationship  with  the  communities  to 
which we currently provide services (or to which we are interested in providing services in the future), but where 
the  State government  has  no  granting  authority.   The creation  of the state regulatory  authority  is  currently  under 
analysis. 

Public-Private Partnerships and Growth Acceleration Plan 

The Public-Private Partnership, or PPP, is a form of contract with the public administration used for the concession 
of  services  only  to  private  enterprises,  as  well  as  for  construction  works  coupled  with  the  provision  of  services.  
PPPs are regulated in the State of São Paulo by Law No. 11,688 enacted on May 19, 2004.  PPPs may be used for:  
(1)  implantation,  expansion,  improvement,  reform,  maintenance,  or  management  of  public  infra-structure;  (2) 
provision of public services; and (3) exploitation of public assets and non-material rights belonging to the State.  

Payment  is  conditional  upon  performance.    The  payment  may  be  collected  through:    (1)  fares  paid  by  users;  (2) 
assignment of credits belonging to the Public Administration, except taxes; and (3) transfer of rights related to the 
commercial exploitation of public assets. 

Law  No.11,688  also  authorized  the  creation  of  Companhia  Paulista  de  Parcerias  —  CPP.    CPP  may  grant 
guarantees, enter into insurance contracts, and participate in PPP contracts. 

In  January  2007,  the  President  of  Brazil  announced  a  new  Growth  Acceleration  Plan,  known  as  the  “PAC”,  that 
includes major investments in infrastructure services, including the service provision of water and sewage, housing, 
as well as highways, airports, ports, energy, that would benefit the poor population of Brazil.  The Plan calls for a 
total of R$504,0 billion (unaudited) through 2010 and most part of this amount would be provided by state-owned 
companies and the private sector, while the rest would come from the federal government. 

Public Bidding Procedures 

Pursuant  to  the  Federal  Public  Bidding  Law,  the  public  bid  process  commences  with  publication  by  the  granting 
authority  in  the  federal,  state  or  municipal  official  gazette,  as  the  case  may  be,  and  another  leading  Brazilian 
newspaper, of an announcement that it will carry out a public bidding contest pursuant to provisions set forth in an 
edital (invitation to bid).  The invitation to bid must specify, among other terms: 

46 

 
 
 
 
 
 
• 

• 

• 

• 

• 

• 

the purpose, duration and goals of the bid; 

the participation of bidders, either individually or forming a consortium; 

a  description  of  the  qualifications  required  for  adequate  performance  of  the  services  covered  by 
the bid; 

the deadlines for the submission of bids; 

the criteria used for selection of the winning bidder; and 

a list of the documents required to establish the bidder’s technical, financial and legal capabilities.  
The  invitation  to  bid  is  binding  on  the  granting  authority.    Bidders  may  submit  their  proposals 
either individually or in consortia, as provided for in the invitation to bid. 

After  receiving  proposals,  the  granting  authority  will  evaluate  each  proposal  according  to  the  following  criteria, 
which must have been set forth in the invitation to bid: 

• 

• 

• 

• 

the technical quality of the proposal; 

lowest cost or lowest public service tariff offered; 

a combination of the criteria above; or 

the largest amount offered in consideration for the concession. 

The Edital bid the concession power to its terms. 

The provisions of the State Public Bidding Law parallel the provisions of the Federal Public Bidding Law. 

The Federal and State bidding laws will apply to us in the event that we seek to secure new concessions.  Moreover, 
these bidding laws currently apply to us with respect to obtaining goods and services from third parties for, among 
other things, our business operations or in connection with our capital expenditure program, in each case subject to 
certain exceptions. 

Water Usage 

In July 2000, the National Water Agency, a federal agency under the Ministry of the Environment, was established 
to  develop  the  National  System  for  Water  Resources  Management.    According  to  existing  law,  federal  and  state 
agencies  are  authorized  to  collect  charges  related  to  water  usage  from  entities,  such  as  us,  for  the  abstraction  of 
water  from,  or  dumping  of  sewage  into,  water  resources  controlled  by  these  agencies.    The  charges  collected  by 
these  agencies  will  be  used  to  sponsor  studies,  programs,  projects  and  constructions  provided  for  in  the  Water 
Resources  Plan  (Plano  de  Recursos  Hídricos)  and  for  the  payment  of  expenses  concerning  the  creation  of  the 
Federal System for Water Resources Managing (Sistema Nacional de Gerenciamento de Recursos Hídricos), as well 
as administrative costs regarding the bodies and entities pertaining thereto and they may be loaned or provided as 
grants  or  subsidies  to  governmental  agencies  and  corporations,  including  us,  for  use  in  the  development  and 
maintenance of water resources.   

The legislature of the State and the Federal Government enacted legislation under which we must pay charges to the 
Federal Government, the State or an agency in respect of the use of water from specified sources.  Since February 
2004, we have been incurring expenses in connection with the use of water from the Paraíba do Sul River Basin and 
since January 2006, from the Piracicaba, Capivari and Jundiaí River Basin.   

State law establishes the basic principles governing the development and use of water resources in the State of São 
Paulo in accordance with the State Constitution.  These principles include: 

47 

 
 
• 

• 

• 

• 

• 

• 

• 

rational utilization of water resources, with service to the population identified as having priority; 

optimizing the economic and social benefits resulting from the use of water resources; 

protection of water resources against actions which could compromise current and future use; 

defense against critical hydrographic events which could cause risk to the health and safety of the 
population or economic and social losses; 

development of hydro transportation for economic benefit; 

development of permanent programs of conservation and protection of underground water sources 
against pollution and excessive exploitation; and 

prevention of erosion of land in urban and rural areas, with a view to protecting against physical 
pollution and silting of water resources. 

In order to implement these principles, authorizations granting a right of use are required from the relevant public 
authority for water usage (whether for collection, release of effluents or other otherwise), modification of the regime 
and  modification  of  the  quality  or  the  quantity  of  the  existing  water.    In  the  case  of  rivers  under  the  Federal 
Government’s  domain  (rivers  crossing  more  than  one  state),  the  National  Water  Agency  is  the  public  authority 
which grants the authorization.  With respect to the rivers under a state’s domain, the applicable state authority has 
jurisdiction  to grant the right of use.  In the State of São Paulo, the State Department of Water and  Energy is the 
public  authority  responsible  for  granting  such  authorizations.    According  to  a  report  prepared  in  May  2001,  the 
granting of rights for our water usage should be regulated in 391 of our projects. 

Under state law, implementation of any project that involves the use of surface or underground water requires prior 
authorization or licensing from the competent government authority. 

The  State  Department  of  Water  and  Energy  has,  as  its  objectives,  establishing  (1)  a  policy  for  the  use  of  water 
resources with a view to developing the water business of the State, and (2) plans, studies and projects related to the 
integral  use  of  water  resources,  directly  or  by  means  of  agreements  with  third  parties.    The  State  Department  of 
Water  and  Energy  has  established  the  standards  which  regulate  abstraction  of  water  from  water  resources  in  the 
State of São Paulo. 

On  December  29,  2005,  State  Law  No.12,183  established  the  basis  for  the  fees  charged  by  governmental  water 
agencies in the State of São Paulo for the abstraction of water from the State of São Paulo’s water resources.  The 
fees will be implemented gradually and a specific official register of users of water resources will be created.  The 
proposed fees must be, in each case, approved by a decree from the State Governor, after the consideration by the 
State Department of Water and Energy.  State Law No. 12,183 also established that, until December 2009, the fees 
charged for the use of water resources by public or private water and sewage services providers will correspond to 
50% of the fees charged for the other users of water resources.  Fines applied for the non-payment of the fees may 
vary from 2% of the debt to the suspension of the right of use of the water resources. 

Water Quality 

Administrative Rule No. 518/04, issued by the Ministry of Health of the Federal Government provides the standards 
for drinking water for human consumption in Brazil.  This rule conforms to the U. S. Safe Drinking Water Act and 
the regulations enacted by the U.S. 70 Environmental Protection Agency, establishing rules for sampling and limits 
related to substances that are potentially hazardous to health. 

In compliance with Brazilian law, the physical-chemical, organic and bacteriological analyses carried out for water 
quality control follow the methodologies of the “Standard Methods for Water and Wastewater” (21st edition) of the 
American Water Works Association.  

48 

 
 
Decree  No.  5,440/05  provides  for  the  obligation  to  disclose  the  quality  of  water  to  consumers.    We  have  been 
complying  with  these  regulations  by  publishing  the  relevant  information  in  monthly  bills  and  annual  reports 
delivered to all consumers that we serve. 

Sewage Requirements 

State law sets forth regulations regarding pollution and protection of the environment in the State of São Paulo.  The 
standards  for  disposal  of  industrial  effluents  set  forth  in  this  law  broadly  correspond  to  the  standards  for  such 
disposal set by the U.S. Environmental Protection Agency.  State law generally prohibits the discharge of pollutants 
into water, air or land in the State of São Paulo. 

State law provides that, in areas in which there exists a public sewage system, all effluents of a “polluting source” 
must  be  discharged  to  such  system.    It  is  the  responsibility  of  the  polluting  source  to  connect  itself  to  the  public 
sewage  system.    All  effluents  to  be  discharged  are  required  to  meet  certain  characteristics,  which  allow  such 
effluents to be treated by our treatment facilities and discharged in an environmentally safe manner.  Effluents which 
exceed such characteristics are prohibited from being discharged into the public sewage system.  State law requires 
industries  that  produce  industrial  sewage  to  pre-treat  such  sewage  so  that  maximum  levels  of  certain  parameters, 
such  as  pH,  temperature,  sediment,  grease,  oil  and  metals,  are  reduced  to  environmentally  sound  levels  prior  to 
release into our sewer lines. 

Environmental  Sanitation  Technology  Company  (Companhia  de  Tecnologia  de  Saneamento  Ambiental)  or 
CETESB,  a  State-controlled  company  under  the  jurisdiction  of  the  Secretariat  of  the  Environment  of  the  State,  is 
authorized under State law to monitor discharges of pollutants into the environment and to enforce the requirements 
of State law.  CETESB is responsible for operating Installation and Operation Licenses issued to sewage treatment 
facilities  and  other  pollution  sources.    Although  we  have  not  received  formal  authorization  from  CETESB  to 
discharge raw sewage into waters, we continue to discharge such sewage.  Our capital expenditure program includes 
the Tietê Project, which is designed to reduce the discharge of raw sewage into the Tietê River, a major river in the 
São  Paulo  Metropolitan  Region.    CETESB  participates  in  the  development  of  this  project.    There  can  be  no 
assurance that we will  not be required in the future to obtain specific consents or authorizations for discharges of 
raw sewage. 

The  disposal  of  sludge  must  also  meet  the  requirements  of  State  law.    CETESB  also  regulates  the  discharge  of 
effluents  into  bodies  of  water  under  State  law  and  must  approve  all  of  our  treatment  facilities  without  prejudging 
whether we have complied with standards established by federal legislation. 

State law also stipulates the basis for fees to be charged for discharging effluents into the State of São Paulo’s water 
resources.  Although neither the State nor its agencies currently assesses fees for the discharges, we cannot assure 
you that the fees will not be charged in the future. 

Some municipalities of the State of São Paulo have enacted municipal laws requiring us to charge a fixed fee, and 
not a tariff, for sewage services being provided.  To date, we have not been the subject of the enforcement of these 
laws. 

Tariff Regulation of São Paulo  

The tariffs we set for our services are to some extent subject to Federal and State regulation. 

On  December  16,  1996,  the  Governor  of  the  State  issued  a  decree  which  approved  the  existing  tariff  system  and 
allowed us to continue to set our own tariffs.  We have set our tariffs based on the general objectives of maintaining 
our financial condition and preserving “social equity” in terms of the provision of water and sewage services to the 
population  while providing  a  return on  investment.    The  Governor’s  decree also directs us  to apply  the  following 
criteria in determining our tariffs: 

• 

category of use; 

49 

 
 
• 

• 

• 

• 

• 

• 

capacity of the water meter; 

characteristics of consumption; 

volume consumed; 

fixed and floating costs; 

seasonal variations; and 

social and economic conditions of residential customers. 

In determining tariffs, we may also consider the costs associated with the exploitation of basic sanitation services, 
depreciation,  provision  for  bad  debts,  amortization  of  expenses  and  adequate  remuneration  for  investments.    We 
usually submit new tariffs to the Governor of the State for approval, although we are not required by law to do so.  
We  implemented  a  new  readjustment  formula  designed  to  better  reflect  costs  in  August  2003.    See  “—Business 
Overview—Tariffs.” 

We  maintain  three  different  tariff  schedules,  depending  upon  whether  a  customer  is  located  in  the  São  Paulo 
Metropolitan Region or the interior or coastal regions comprising our Regional Systems.  There are four levels of 
volume  consumed  for  each  category  of  customer,  except  for  the  residential  social  and  favelas  (shantytowns)  that 
present five levels of volume consumed.  Customers are billed on a monthly basis.  We are also authorized to enter 
into  individual  contracts  with  certain  customers,  such  as  municipalities,  to  sell  water  or  sewage  services  on  a 
wholesale basis. 

Our tariff system also establishes criteria for billing and collection of services and for the publicity to be given to 
such criteria and tariffs.  Tariffs are published in the Official Gazette of the State of São Paulo (Diário Oficial do 
Estado de São Paulo). 

We may be subject to a federal law which, in the case of water and sewage services, provided pursuant to certain 
concessions, effectively prohibits tariffs that would produce a return on assets in excess of 12% per annum.  Return 
on  assets  is  calculated  using  operating  income  (before  financial  and  certain  other  expenses)  measured  against 
operational  assets  (property,  plant  and  equipment  and  certain  other  assets),  based  on  our  financial  statements 
prepared  in  accordance  with  the  Brazilian  Corporate  Law  Method.    We  could  be  subject  to  the  above  return  on 
assets limitation in adjusting  tariffs because substantially  all of our concessions were granted during the period in 
which these rate regulations were in effect.  We are not, however, subject to such limitations in setting tariffs under 
our newer concessions.  The above return on assets limitation does not apply to renewals of existing concessions. 

In  addition  to  the  specific  regulation  mentioned  above,  we  are  also  subject  to  general  rules  such  as  periodic 
readjustments established by Law No. 9,069/95 which established, among other things, the Real Plan. 

Governmental Restrictions on Incurrence of Debt 

On  June  30,  1998,  the  Central  Bank  issued  a  resolution  amending  certain  conditions  that  must  be  observed  with 
respect to the external credit operations (i.e., foreign currency borrowings) of states, the Federal District of Brasilia, 
municipalities  and  their  respective  autarquias  (agencies),  foundations  and  non-financial  companies,  including  us.  
This  resolution  provides,  among  other  things,  that,  with  certain  exceptions  applicable  to  the  importation  of  goods 
and services: 

• 

the  proceeds  of  external  credit  operations  must  be  exclusively  used  to  refinance  outstanding 
financial  obligations  of  the  issuer,  with  preference  given  to  those  obligations  that  have  a  higher 
cost and a shorter term, and, until used for such purposes, the proceeds shall remain deposited, as 
directed by the Central Bank, in a pledged account; and 

50 

 
 
• 

the  total  amount  of  the  contractual  obligation  must  be  subject  to  monthly  deposits  in  a  pledged 
account, equal to the total debt service obligation, including principal and interest, divided by the 
number of months that the obligation is to be outstanding. 

The  Central  Bank  resolution  further  provides  that  the  requirements  described  above  do  not  apply  to  financing 
transactions  involving  multilateral  or  official  organizations  such  as  the  World  Bank,  the  Inter-American 
Development Bank or the JBIC.  The Central Bank regulation implementing this resolution provides, among other 
things, that the account referred to in the first bullet point above must be an account opened in a federal financial 
institution, which is to hold such funds until released for the purpose of refinancing outstanding obligations of the 
issuer.    The  Central  Bank  regulation  further  provides  that  the  account  described  in  the  second  bullet  point  above 
must be an escrow account to be opened in a federal financial institution and to secure the payment of principal and 
interest on the external debt. 

Our external credit transactions are also subject to the approval of the National Treasury Secretariat and the Central 
Bank,  which,  after  reviewing  the  financial  terms  and  conditions  of  the  transaction,  will  issue  an  approval  for  the 
closing of the foreign exchange transaction relating to the entry of the funds into Brazil and, following such entry 
and  at  our  request,  an  electronic  certificate  of  registration  through  which  all  scheduled  payments  of  principal, 
interest and expenses will be remitted by us.  The electronic certificate of registration grants the borrower access to 
the market for foreign exchange. 

Finally,  our  external  credit  transactions  are  also  subject  to  the  prior  approval  of  the  Secretariat  of  Finance  of  the 
State. 

Lending Limits of Brazilian Financial Institutions 

The National Monetary Council resolutions limit the amount that Brazilian financial institutions may lend to public 
sector companies, such as us.  Financing of projects which are put up for international bid and any financing in reais 
provided to the Brazilian counterpart of such international bids are excluded from these limits. 

Conselho Estadual de Saneamento—Conesan 

State  law  regulates  the  provision  of  sanitation  services  and  establishes  rules  for  the  planning  of  sanitation-related 
public  works  in  the  State  of  São  Paulo.    The  State  plan  for  public  sanitation  services  must  integrate  institutional, 
technological, financial and administrative resources to ensure that a healthy environment is created for inhabitants 
of the State of São Paulo.  The State plan must also assist in developing and organizing the sanitation sector in the 
State of São Paulo. 

Pursuant to State law, the State’s sanitation policy is implemented by the State Sanitation System (Sistema Estadual 
de Saneamento).  The State Sanitation Fund (Fundo Estadual de Saneamento) collects funds and manages resources 
to fund the programs approved in the sanitation plan. 

The State Sanitation Council (Conselho Estadual de Saneamento) must approve proposals related to the sanitation 
plan and prepare an annual report regarding environmental health issues confronting the State.  The State Sanitation 
Council establishes protocols for the development of investment programs approved by the State Sanitation System 
and resolves disputes related to the State Sanitation System’s implementation of the sanitation plan. 

4.C. Organizational structure 

Not applicable. 

4.D. Property, Plant and Equipment 

Our  principal  properties  consist  of  reservoirs,  water  treatment  facilities,  water  distribution  networks  consisting  of 
water  pipes,  water  mains,  water  connections  and  water  meters,  sewage  treatment  facilities,  and  sewage  collection 
networks  consisting  of  sewer  lines  and  sewage  connections.    As  of  December  31,  2006,  we  owned  197  water 

51 

 
 
treatment  facilities  and  61,469  kilometers  of  water  pipes  and  mains,  446  sewage  treatment  facilities  and  39,126 
kilometers of sewer lines, as well as 16 water quality control laboratories. 

We  own  our  headquarters  building  and  all  other  major  administrative  buildings.    We  have  pledged  some  of  our 
properties  as  collateral  to  the  Federal  Government  in  connection  with  a  long-term  financing  transaction  we  have 
entered into with the World Bank that was guaranteed by the Federal Government.  We have also pledged part of 
our assets in the amount of R$249.0 million as collateral with respect to our indebtedness under the Special Program 
for  Payment  of  Federal  and  Social  Security-Related  Taxes  in  Installments  (Programa  de  Parcelamento  Especial 
para Impostos Federais e Previdenciários), or PAES program, as set forth by Law No. 10,684, dated May 30, 2003.  
Three of our properties in the amount of R$60.5 million were pledged as collateral for the financing granted by the 
International Bank for Reconstruction and Development.   

As of December 31, 2006, the total net book value of our property, plant and equipment was R$14,332.6  million, 
including concession assets acquired (intangible assets).   

All of our material properties are located in the State of São Paulo. 

ITEM 5.  OPERATING AND FINANCIAL REVIEW AND PROSPECTS 

The following management’s discussion and analysis of financial condition and results of operations should be read 
in  conjunction  with  our  audited  financial  statements  included  in  this  annual  report.    This  annual  report  contains 
forward-looking statements that involve risks and uncertainties.  Our actual results may differ materially from those 
discussed  in  the  forward-looking  statements  as  a  result  of  various  factors,  including,  without  limitation,  those  set 
forth in “Risk Factors”. 

The financial statements in this annual report have been prepared in accordance with the Brazilian Corporate Law 
Method, which differs in certain significant respects from U.S. GAAP.  We have included a discussion below of the 
material  differences  between  the  Brazilian  Corporate  Law  Method  and  U.S.  GAAP  related  to  each  critical 
accounting  policy  in  our  audited  financial  statements.    For  additional  information  regarding  other  differences 
between the Brazilian Corporate Law Method and U.S. GAAP, please see note 23 to our financial statements. 

In  the  following  discussion,  references  to  increases  or  decreases  in  any  period  are  made  by  comparison  with  the 
corresponding prior period, except as the context otherwise indicates. 

5.A. Operating and Financial Review and Prospects 

Overview 

We operate water and sewage systems in the State of São Paulo, including in the City of São Paulo, Brazil’s largest 
city, and in more than one-half of the other municipalities in the State of São Paulo.  We also make wholesale sales 
of water to six additional municipalities in which we do not operate water systems.   

The São Paulo Metropolitan Region, which includes the City of São Paulo, is our most important service territory.  
With a population of approximately 19.5 million, the São Paulo Metropolitan Region accounted for approximately 
74.5%,  75.5%  and  75.8%  of  our  gross  revenue  from  sales  and  services  in  2004,  2005  and  2006,  respectively.  
Approximately 71.8% of the property, plant and equipment reflected on our balance sheet as of December 31, 2006 
is located in this region.  In an effort to respond to demand in the São Paulo Metropolitan Region and because the 
region represents the principal opportunity to increase our net revenue from sales and services, we have dedicated a 
major  portion  of  our  capital  expenditure  program  to  expand  the  water  and  sewage  systems  and  to  increase  and 
protect water sources in this region.  Our capital expenditure program is our most significant liquidity and capital 
resource requirement.

Factors Affecting Our Results of Operations 

Our  results  of  operations  and  financial  condition  are  generally  affected  by  our  ability  to  raise  tariffs,  general 
economic  conditions  in  Brazil  and,  in  some  previous  periods,  meteorological  conditions.    In  2004,  results  of 
operations  and  financial  condition  were  also  significantly  affected  by  an  increase  in  bad  debt  expenses  net  of 
recoveries,  increases  in  electricity  costs,  and  increases  in  payments  for  outside  services.    In  2005,  hydrological 
conditions  improved  and  with  the  increase  in  efficiencies  in  our  system,  we  were  able  to  increase  capacity  and 
production.    We  were  therefore  able  to  increase  revenues  reflecting  both  operational  improvement  and  greater 
demand arising from the end of our water usage reduction bonus program.  In 2006, our results of operations and 
financial  condition  were  affected  by  an  increase  in  the  invoiced  volume  of  water  and  sewage,  as  well  as  by  a 
decrease  in  our  financial  expenses,  as  a  result  of  our  strategy  to  actively  manage  our  capital  market  debts. 
Additionally, in 2006, our results of operations and financial condition was negatively affected by the adjustment of 
R$  93.8  million,  as  a  result  of  an  analysis  and  conciliation  procedure  related  to  the  accounting  balance  of  our 
accounts receivable.  See note 5 to our financial statements.  

Effects of Tariff Increases 

Our results of operations and financial condition are highly dependent upon our ability to set and collect adequate 
tariffs for our water and sewage services.  Although we generally have broad power to establish tariffs within our 
service territories, this power is, in practice, subject to limits due to, among other factors, the following: 

• 

• 

• 

political considerations arising from our status as a State-controlled company; 

anti-inflation measures promulgated by the Federal Government from time to time; and 

federal laws that in some circumstances limit to 12.0% per year the return on the assets of some of 
our concessions. 

Tariffs have often failed to keep up with inflation during periods of high inflation in the past.  During the past few 
years, we generally have been able to raise tariffs in line with increases in cost of sales and services and operating 
expenses and to support our liquidity and capital resource requirements.  In 2000, we did not raise tariffs due to the 
State policy for that year of not increasing tariffs for many public services.  In June 2001, however, we increased our 
average  tariff  by  approximately  13.1%,  which  was  broadly  in  line  with  prevailing  inflation  rates  in  Brazil  since 
mid-1999  as  measured  by  the  consumer  price  index,  and  in  August  2002,  we  increased  our  tariffs  by  8.2%.    In 
August 2003, we increased our tariffs for water and sewage services by 18.9%, in August 2004 we raised our tariffs 
for water and sewage services by 6.8% and in August 2005 we raised our tariffs for water and sewage services by 
9.0%.  In August 2006, we increased our tariffs by 6.71%. 

Since  August  2003,  our  tariffs  have  been  determined  using  a  transparent  formula  which  accounts  for  inflation, 
covers  our  operating  costs  and  other  expenses  and  provides  for  a  return  on  investment.    Tariffs  have  historically 
been  adjusted  once  a  year  and  for  periods  of  at  least  12  months.    We  are  currently  evaluating  and  considering  a 
potential revision to our tariff structure in order to improve our return on investment.  We concluded a study on this 
topic in January 2006 and our board of executive officers created a team to evaluate and, if needed, to update and 
report  the  actions  necessary  for  the  implementation  of  the  recommendations  of  the  study.    To  date,  we  have  not 
defined  the  term  for  these  actions  and  we  believe,  based  on  our  advisors’  opinion,  that  we  will  implement  the 
recommendations of the study within four years.  

The  new  basic  sanitation  law,  Law  No.  11,445,  does  not  affect  terms  and  conditions  related  to  tariff  adjustments 
under our existing concessions.  Contracts that are currently in effect will be adjusted according to the formula that 
we have applied to them.  Pursuant to Law No. 11,445, as a general rule, the new state regulatory authority that will 
be created and replace the Commission for the Regulation of Sanitation Service of the State of São Paulo, will be 
responsible for setting and adjusting tariffs.  While the new state regulatory authority is not created, the Sanitation 
and Energy Secretariat of the State of São Paulo will be temporarily in charge of these responsibilities.

Effects of Brazilian Economic Conditions 

As a company with all of its operations in Brazil, our results of operations and financial condition are affected by 
general  economic  conditions  in  Brazil,  particularly  by  currency  exchange  rate  movements,  inflation  rates  and 
interest rate levels.  For example, the general performance of the Brazilian economy affects demand for water and 
sewer  services,  and  inflation  affects  our  costs  and  our  margins.    The  Brazilian  economic  environment  has  been 
characterized by significant variations in economic growth rates. 

General Economic Conditions.  In 2002, several negative economic factors adversely affected consumer confidence 
levels  in  Brazil.    Prior  to  and  subsequent  to  the  presidential  elections  in  November  2002,  there  was  substantial 
uncertainty relating to Brazil’s own political and economic future. 

In 2003, the new administration largely continued the macroeconomic policies of the previous administration.  The 
real  appreciated  by  22.3%  against  the  U.S.  dollar  in  2003  to  R$2.8892  per  US$1.00  as  of  December  31,  2003.  
Inflation for 2003, as measured by the IGP-M, was 8.7%.  However, real gross domestic product decreased by 0.2% 
during  2003  largely  because  the  very  high  interest  rates  that  prevailed  at  the  beginning  of  2003  also  constrained 
economic growth.  The  Brazilian economy showed signs of improvement in the third and fourth quarters of  2003 
that  continued  through  2004.    During  2004  real  gross  domestic  product  grew  by  5.2%,  inflation  was  12.4%  as 
measured by the IGP-M and the real appreciated 8.8% against the U.S. dollar as the real/U.S. dollar exchange rate 
decreased to 2.6544 reais as of December 31, 2004. 

The  principal  events  affecting  the  Brazilian  macroeconomy  in  2005  were  the  corruption  allegations  against 
government  officials  and  Brazilian  house  representatives  of  the  current  president's  support  base,  and  the  Central 
Bank’s efforts to meet the goal of 5.1% annual inflation, which resulted in the maintenance of high levels of interest 
rates, starting from November, the Central Bank has begun a process of reducing the official interest rate in order to 
encourage economic growth. As of December 31, 2005, the official interest rate was 18.00%. 

In  2006,  the  appreciation  trend  continued  and  the  real  appreciated  by  7.5%  against  the  U.S.  dollar  between 
December 31, 2005 and 2006.  Notwithstanding the real’s appreciation, Brazil’s trade surplus was US$46.1 billion.  
The average unemployment rate increased from 8.3% for the year ended December 31, 2005, to 10.0% for the year 
ended December 31, 2006, in the principal metropolitan regions of Brazil, according to IBGE estimates.  In 2006, 
the inflation rate, as measured by the IGP-M, was 3.8%. 

Interest Rates.  Interest rate levels in Brazil are closely linked to exchange rate movements and inflation rates.  High 
domestic interest rates result in increases in our  financial expenses and  also negatively affect our ability to obtain 
financing, on a cost-effective basis, in domestic capital and lending markets.  As a result, we may continue to require 
substantial  amounts  of  foreign  currency-denominated  debt  in  order  to  satisfy  our  liquidity  and  capital  resource 
requirements, which increase our exposure to exchange rate movements as discussed below. 

54 

 
 
 
 
The Central Bank increased the official interest rate to 26.3% on February 19, 2003 and decreased it to 15.8% on 
April 14, 2004.  The Central Bank increased the official interest rate to 17.74% on December 15, 2004.  During the 
first  four  months  of  2005,  the  Central  Bank  continued  to  raise  the  official  interest  rate,  which  reached  19.5%  on 
April 20, 2005.  However, starting from November, the Central Bank has begun a process of reducing the official 
interest rate.  On December 31, 2005, the official interest rate was 18.0%.  In 2006, the Central Bank continued to 
reduce the official interest rate, reaching 13.19%. 

We  have  not  utilized  any  derivative  financial  instruments,  or  any  hedging  instruments  to  mitigate  interest  rate 
fluctuations.    We  do,  however,  continually  monitor  market  interest  rates  in  order  to  evaluate  the  possible  need  to 
refinance our debt. 

Inflation.    Inflation  affects  our  financial  performance  by  increasing  our  costs  of  services  rendered  and  operating 
expenses.  In addition, all of our real-denominated debt is indexed to take into account the effects of inflation.  Most 
of our real-denominated debt provides for inflation-based increases in the respective principal amounts of that debt, 
which  increases  are  determined  by  reference  to  the  daily  government  interest  rate  (Taxa  Referencial-TR)  plus  an 
agreed  margin.  We cannot assure that we  will be able, in  future periods, to increase tariffs to  offset, in full or in 
part, the effects of inflation.

Currency  Exchange  Rates.    We  had  total  foreign  currency-denominated  indebtedness  of  R$1,472.8  million  as  of 
December 31, 2006.  In the event of further significant devaluations of the real in relation to the U.S. dollar or other 
currencies, the cost of servicing our foreign currency-denominated obligations would increase as measured in reais, 
particularly as our tariff and other revenue are based solely in reais.  In addition, any significant devaluation of the 
real will increase our financial expenses as a result of foreign exchange losses that we must record.  For example, 
the  34.3%  devaluation  of  the  real  in  2002  increased  our  financial  expenses  and  negatively  affected  our  overall 
results of operations for that year.  In contrast, in 2003, the real appreciated 22.3% against the U.S. dollar, which 
resulted in a foreign exchange gain of R$540.6 million.  The 8.8% appreciation of the real against the U.S. dollar in 
2004 led to a foreign exchange gain of R$179.7 million.  The 13.4% appreciation of the real against the U.S. dollar 
in 2005 led to a foreign exchange gain of R$312.1 million.  The 9.5% appreciation of the real against the U.S. dollar 
in 2006 led to a foreign exchange gain of R$96.1 million. 

The following table shows the devaluation (appreciation) of the real against the U.S. dollar, the period-end exchange 
rates and average exchange rates for the periods indicated:

At times, we enter into forward exchange transactions and financial funding transactions in reais to mitigate foreign 
currency  exposure.  In  addition,  we  have  monitored,  overseen  and  controlled  our  indebtedness  denominated  in 
foreign  currency,  taking  advantage  of  market  opportunities  to  improve  the  profile  of  our  indebtedness  and  reduce 
our costs.

Effects of Drought 

Brazil experienced a prolonged and severe drought during 2000 and 2001, although historically droughts have not 
impacted  all  of  our  water  supply  systems  equally.    During  this  period,  the  São  Paulo  Metropolitan  Region,  in 
particular, faced its worst drought in 65 years.  As a result, from mid-June to mid-September in 2000, we rationed 
water  in  the  south  of  the  São  Paulo  Metropolitan  Region,  affecting  approximately  3.5  million  people,  or 
approximately  20%  of  the  total  population  of  this  region.    Under  this  rationing,  water  was  made  available  to  our 
customers  for  only  two  out  of  every  three  days.    During  this  period  of  rationing,  we  also  reduced  our  total  water 
production by approximately 8%.  From April 2001 through January 2002, we rationed water in the west of the São 
Paulo  Metropolitan  Region,  affecting  approximately  300,000  people.    Under  this  rationing,  water  was  made 
available to these 300,000 customers for only 40 out of every 78 hours.  Throughout 2003 rain levels were below 
average resulting in a weak replenishment of our reservoirs, particularly in the Cantareira system, the largest water 
supply system in the São Paulo Metropolitan Region.  From October to December 2003, we rationed water on the 
western  part  of  the  São  Paulo  Metropolitan  Region,  served  by  the  Alto  Cotia  system,  affecting  approximately 
450,000 people, or approximately 2% of the region’s population.  Under this rationing, water was available to those 
people for three days, followed by two days of rationing.  During this period our total water production volume was 
reduced by 0.8%.  As a result of the drought, our revenue declined as our volume of water billed decreased, and our 
costs increased because of required expenditures to protect and develop water sources and to preserve water quality.  
The impact that droughts have may vary across our different systems, which may allow us to mitigate the effects of 
any  particular  drought.    The  effects  of  the  drought  continued  to  affect  our  systems  through  2004.    In  order  to 
minimize the effects of this drought we implemented a water usage reduction bonus program.  Due to this program 
and  the  return  to  normal  rainfall  levels  that  occurred  throughout  2004  and  early  2005,  the  conditions  of  our 
reservoirs have improved.  In 2006, the rainfall was sufficient to enable the increase in the volume of water held in 
our reservoirs.  

Effects of the Water Usage Reduction Bonus Program 

In  order  to  encourage  customers  to  use  less  water  in  drought  conditions,  in  2004  we  instituted  a  “bonus”  system, 
rewarding customers who reduced their water consumption by specified amounts.  The “bonus” was shown on each 
customer’s bill as a discount, and was calculated based on the customer’s water usage each month, and applied to 
decrease the amount payable by that customer. 

This water usage reduction program took effect on March 15, 2004 and ended on September 15, 2004, and had the 
following effects: 

• 

• 

• 

customers  reduced  their  overall  water  usage,  leading  to  lower  revenues  from  lower  volumes  of 
water and sewage services; 

we discounted the amounts payable by customers who successfully lowered their water usage; and 

many  customers,  by  reducing  their  water  usage,  shifted  their  households  into  a  lower  tariff 
category. 

Our results for 2004 reflect the impact of these effects, all of which lowered our revenue from March 15, 2004 to 
September  15,  2004,  thus  affecting  bills  sent  out  through  October.    In  2004,  the  volume  of  water  and  sewage 
invoiced  decreased  by  1.4%,  and  our  revenue  from  water  and  sewage  services  provided  to  the  São  Paulo 
Metropolitan Region decreased by R$74.1 million, as a result of our water reduction program.  This reduction was 
offset in part by the positive impact of tariff readjustments. 

Critical Accounting Policies, Practices and Estimates 

Critical  accounting  policies  and  practices  are  those  that  are  both  (1)  important  to  the  portrayal  of  our  financial 
condition and results of operations and (2) require management’s most difficult, subjective or complex judgments, 
often  as  a  result  of  the  need  to  make  estimates  about  the  effect  of  matters  that  are  inherently  uncertain.    As  the 
number  of  variables  and  assumptions  affecting  the  possible  future  resolution  of  the  uncertainties  increase,  those 

56 

 
 
judgments  become  even  more  subjective  and  complex.    In  order  to  provide  an  understanding  about  how  our 
management  forms  its  judgments  about  future  events,  including  the  variables  and  assumptions  underlying  the 
estimates,  and  the  sensitivity  of  those  judgments  to  different  circumstances,  we  have  identified  the  critical 
accounting policies and practices discussed below. 

Our management discussion and analysis of financial condition and results of operations are based upon our primary 
financial  statements,  which  have  been  prepared  in  accordance  with  the  Brazilian  Corporate  Law  Method,  which 
differs in significant respects from U.S. GAAP.  We have included a discussion on material differences between the 
Brazilian  Corporate  Law  Method  and  U.S.  GAAP  related  to  each  critical  accounting  policy  in  our  audited 
financial statements. 

Allowance for Doubtful Accounts 

We record allowance for doubtful accounts in an amount that our management considers sufficient to cover probable 
losses,  based  on  an  analysis  of  customer  accounts  receivable,  taking  into  consideration  the  expected  recovery  in 
different categories of customers.  We record an allowance for doubtful accounts for balances receivable in excess 
of R$5,000 and overdue for more than 360 days, and for balances receivable in excess of R$30,000 and overdue for 
more than 360 days as to which we have commenced judicial collection proceedings.  The amount is thus calculated 
and adjusted when it is in excess or insufficient, based on an aging analysis of receipts and on the expected recovery 
at different categories of customers.  Accounts receivable balances under R$5,000 and overdue for more than 180 
days are written off as a direct charge to income.   

Provisions  for  the  allowance  for  doubtful  accounts  are  included  in  selling  expenses,  net  of  recoveries.    The  net 
charge  to  this  allowance  was  R$37.6  million  in  2003,  R$241.6  million  in  2004  and  R$255.3  million  in  2005.    In 
2006, it was R$411.9 million (excluding the effects of the adjustment of R$93.8 million, as a result of an analysis 
and  conciliation  procedure  related  to  the  accounting  balance  of  our  accounts  receivable,  the  net  charge  to  this 
allowance in 2006 was R$318.2 million).   

Our  methodology  for  determining  the  allowance  for  doubtful  accounts  receivable  requires  significant  estimates, 
considering  a  number  of  factors  including  historical  collection  experience,  current  economic  trends,  estimates  of 
forecast  write-offs,  the  aging  of  the  accounts  receivable  portfolio  and  other  factors.    While  we  believe  that  the 
estimates we use are reasonable, actual results could differ from those estimates. 

In addition, we have substantial assets consisting of amounts owed by the State.  These amounts consist primarily of 
accounts receivable for services, reimbursement for pensions paid and amounts due under our December 2001 and 
March 2004 agreement with the State.  See “Item 7.B. Major Shareholders and Related Party Transactions—Related 
Party Transactions”.  We do not reserve against any of these amounts owed by the State due to the following factors: 

• 

• 

we do not expect to incur losses from these accounts receivable; and 

we entered into agreements in September 1997, December 2001 and March 2004 under which the 
State has committed to settle the outstanding amounts due to us described in these agreements by 
applying dividends declared by us to the remaining balance of the accounts receivable owed by the 
State or its controlled entities. 

As  of  December  31,  2006,  the  amounts  owed  to  us  by  the  State  for  the  provision  of  water  and  sewage  services 
included R$148.8  million which was considered overdue as of February 29, 2004.   As of  December 31, 2006 the 
State  owed  us  an  additional  R$308.0  million  in  accounts  receivable  related  to  the  provision  of  water  and  sewage 
services rendered from February 2004.  With respect to reimbursement for pensions paid on behalf of the State, the 
State owed us R$774.5 million as of December 31, 2006 (R$320.6 million of which was acknowledged by the State 
in  an  agreement  with  us  subject  to  a  further  audit  which  has  not  yet  occurred).    We  have  not  established  any 
provisions for any amounts due to us by the State.   

For  U.S.  GAAP  purposes,  the  amounts  receivable  from  the  State  for  pensions  paid  is  not  recorded  as  accounts 
receivable,  but  rather  is  included  as  part  of  our  estimated  pension  and  other  post-retirement  obligations.    Only 

57 

 
 
amounts effectively reimbursed by the State are presented as additional paid-in capital.  No additional differences 
have been identified between accounting policies for accounts receivable and allowance for doubtful accounts under 
the Brazilian Corporate Law Method and U.S. GAAP. 

Indemnities Receivable 

Indemnities receivable is a long-term asset representing amounts receivable from the Municipalities of Diadema and 
Mauá  as  indemnification  for  the  unilateral  withdrawal  by  those  authorities  of  our  water  and  sewage  service 
concessions in 1995.  As of December 31, 2006 this asset amounted to R$148.8 million.   

Under  our  concession  agreements  we  invested  in  the  construction  of  water  and  sewage  systems  in  these 
municipalities  to  meet  our concession service  commitments.   Upon  the  unilateral  termination of  the  Diadema and 
Mauá  concessions,  our  assets  were  impounded  by  the  municipal  authorities,  which  took  on  the  responsibility  of 
providing water and sewage services in these areas.  At that time, we reclassified our property, plant and equipment 
balances  relating  to  the  impounded  assets  to  long-term  assets  (indemnities  receivable)  and  recorded  impairment 
charges  to  reduce  the  carrying  value  of  the  assets  to  the  estimated  recoverable  amounts  for  which  we  had 
contractually agreed as fair compensation with the relevant authorities. 

Our  rights  to  the  recovery  of  these  amounts  are  being  disputed  by  the  municipalities  and  no  amounts  have  been 
received to date.  Based on the advice of legal counsel, we continue to believe that we have the right to receive such 
amounts  and  we  continue  to  monitor  the  status  of  the  legal  proceedings.    However,  the  ultimate  amounts  to  be 
received, if any, will most likely be subject to a final court decision.  As such, actual amounts received could differ 
from those recorded. 

With  respect  to  Mauá,  a  decision  has  been  issued  by  the  lower  court  requiring  Mauá  to  pay  us  the  amount  of 
R$153.2  million  as  compensation  for  the  loss  of  profits.    For  more  information,  see  “Item  8.A.  Financial 
Information—Consolidated Statements and other Information—Legal Proceedings.”   

No  differences  have  been  identified  between  accounting  policies  on  compensation  for  concession  termination 
adopted under the Brazilian Corporate Law Method and U.S. GAAP. 

Property, Plant and Equipment 

Valuation of Long-Lived Assets.  We review long-lived assets, primarily buildings, water and sewage system assets 
and acquired concession assets to be held and used in our business, for the purpose of determining and measuring 
impairment on a recurring basis or when events or changes in circumstances indicate that the carrying value of an 
asset or group of assets may not be recoverable.  Under the Brazilian Corporate Law Method, we evaluate possible 
impairment  by  determining  whether  projected  future  operating  income  is  sufficient  to  absorb  the  depreciation  or 
amortization of long-lived assets, within the context of the balance sheet as a whole. 

Studies  supporting  the  write-offs  for  obsolescence  and  abandonment  of  projects  are  conducted  in  the  accounting 
period of the write-offs based on undiscounted cash flow projections, and approved by our board of directors.  We 
monitor the carrying value of our property, plant and equipment on an on-going basis and adjust the net book value 
to assure future projected operations will be sufficient to recover the carrying value of the assets.  Depreciation is 
provided using the straight-line method based on the estimated useful lives of the underlying assets.  When possible, 
depreciation  rates  are  adjusted  to  take  account  of  changes  in  estimated  prospective  depreciable  lives  as  assets 
are replaced. 

U.S. GAAP Statement  of Financial Accounting Standards, or SFAS, No. 144, “Accounting  for  the Impairment of 
Long-lived Assets,” requires companies  to  periodically evaluate the carrying value  of  long-lived  assets to be held 
and  used,  and  for  long-lived  assets  to  be  disposed  of,  when  events  and  circumstances  warrant  such  a  review.  
Companies are required to identify the smallest unit, or group, of assets at which cash flows generated by the group 
can be  measured.   The  projected undiscounted cash  flows from each such asset group is  compared to  its  carrying 
value.  For those assets for which the projected cash flows are not sufficient to recover the carrying values, a loss is 
recognized to the extent that the carrying value exceeds the fair market value of the assets. 

58 

 
 
In evaluating impairment of our long-lived assets, we make significant assumptions and estimates regarding matters 
that are inherently uncertain, including projections of future operating income and cash flows, future growth rates, 
and the remaining useful lives of the assets, among others.  In addition, projections are computed over an extended 
period of time, which subjects those assumptions and estimates to an even larger degree of uncertainty.  While we 
believe  that  the  estimates  we  use  are  reasonable,  the  use  of  different  assumptions  could  materially  affect 
our valuations. 

No adjustments have been included in the reconciliation from the Brazilian Corporate Law Method to U.S. GAAP to 
take  account  of  differences  between  the  measurement  criteria,  because  no  impairment  provisions  were  required 
based on our analysis of cash flows.  Losses on the write-off of property, plant and equipment arose primarily from 
adjustments upon withdrawal of concession assets, construction-in-progress projects which were deemed no longer 
to be economically feasible and obsolescence write-offs. 

Depreciation  of  Property,  Plant  and  Equipment.    Depreciation  of  our  property,  plant  and  equipment,  primarily 
buildings, water and sewage service and other assets acquired, is provided using the straight-line method based on 
the estimated useful lives of the underlying assets. 

While  we  believe  that  our  estimates  of  current  remaining  estimated  lives  is  reasonable,  the  use  of  different 
assumptions and estimates and changes in future circumstances, could affect the remaining useful lives of our asset, 
which could have a significant impact on our results of operations in the future. 

Loss Contingencies 

We are  a party to a number  of legal  proceedings  involving significant  monetary claims.   These  legal  proceedings 
include, among others, tax, labor, civil, environmental, condemnation and other proceedings.  For a more detailed 
discussion  of  these  legal  proceedings,  see  note  15  to  our  financial  statements.    We  accrue  for  probable  losses 
resulting  from  these  claims  and  proceedings  when  we  determine  that  the  likelihood  that  a  loss  has  occurred  is 
probable and  the amount  of  such loss can  be  reasonably  estimated.   As such, we are  required to  make  judgments 
regarding future events for which we often seek the advice of legal counsel.  As a result of the significant judgment 
required  in  assessing  and  estimating  these  loss  contingencies,  actual  losses  realized  in  future  periods  could  differ 
significantly from our estimates and could exceed the amounts which we have provisioned. 

No differences have been identified between accounting policies on loss contingencies adopted under the Brazilian 
Corporate Law Method and U.S. GAAP. 

Pension Plans 

Plan  G1.    We  sponsor  a  funded  defined-benefit  pension  and  benefits  fund,  or  Plan  G1,  which  is  operated  and 
administered by SABESPREV—Fundação SABESP de Seguridade Social. 

Under the Brazilian Corporate Law Method, prior to January 1, 2002, we recorded pension expense on an accrual 
basis based on our contributions to the plan.  Effective January 1, 2002, in accordance with the issuance of a new 
accounting  standard,  we  began  accounting  for  our  actuarial  obligation  under  Plan  G1.    As  permitted  under  this 
standard,  we  are  amortizing  the  transition  liability  related  to  the  actuarial  value  of  our  obligation  at  the  date  of 
adoption  of the  new  standard over  a period  of  five  years, which is  recorded in our statements of operations as  an 
extraordinary  item,  net  of  the  related  tax  impacts.    For  2005,  pension  costs  charged  to  income  totaled 
R$65.7 million, of which R$53.2 million (net of tax effects, totaling R$35.1million) was presented as “extraordinary 
item  net  of  income  tax  and  social  contribution.”    The  remaining  R$12.5 million  was  charged  to  cost  of  services 
rendered,  general  and  administrative  expenses  and  selling  expenses.    For  2006,  pension  costs  charged  to  income 
totaled  R$56.0  million,  of  which  R$53.2  million  (net  of  tax  effects  totaling  R$35.1  million)  was  presented  as 
“extraordinary item net of income tax and social contribution.”  The remaining R$2.8 million was charged to cost of 
services  rendered,  general  and  administrative  expenses  and  selling  expenses.    Based  on  independent  actuarial 
reports, as of December 31, 2006, our obligation under Plan G1 was R$321.2 million.  See note 13 to our financial 
statements.   

59 

 
 
Under U.S. GAAP, we had already adopted the provisions of SFAS No. 87, “Employers’ Accounting for Pensions” 
prior to 2002, which requires that we recognize an actuarial liability for pension benefits under Plan G1.  While the 
actuarial assumptions used for U.S. GAAP are the same as those used in determining the actuarial liability under the 
Brazilian Corporate Law Method, pension costs and obligations under U.S. GAAP and the Brazilian Corporate Law 
Method are not the same, mainly due to differences related to the first year of application, the amortization of the 
initial  transition  obligation,  amortization  periods  for  other  actuarial  gains  and  losses,  and  actuarial  calculation 
methods, among others.  After the issuance of SFAS 158 “Employers’ Accounting for Defined Benefit Pension and 
Other Postretirement Plans an amendment of FASB Statements No. 87, 88, 106, and 132(R),” in September 2006, an 
employer  is  required  to  recognize  the  overfunded  or  underfunded  status  of  a  defined  benefit  postretirement  plan 
(other  than  a  multi-employer  plan)  as  an  asset  or  liability  in  its  statement  of  financial  position  and  to  recognize 
changes in that funded status in the year in which the changes occur through comprehensive income of a business 
entity or changes in unrestricted net assets of a not-for-profit organization. This statement also requires an employer 
to  measure  the  funded  status  of  a  plan  as  of  the  date  of  its  year-end  statement  of  financial  position,  with  limited 
exceptions.  See note 23 to our financial statements. 

We  are  currently  evaluating  the  possible  introduction  of  a  defined  contribution  plan  for  new  employees  and 
providing existing employees an option to switch to this new plan from Plan G1.  

Plan G0.  Pursuant to a law enacted by the State, some of its employees who provided service to us prior to May 
1974 and retired as employees of ours acquired a legal right to receive supplemental pension payments (which rights 
are referred to as “Plan G0”).  These amounts are paid by us on behalf of the State and are claimed as reimbursement 
from the State.  As such, no pension expense related to Plan G0 is recorded and no future obligations are recorded 
under the Brazilian Corporate Law Method. 

Consistent with the guidance in SEC Staff Accounting Bulletin Topic 5-T (“SAB No. 5-T”), under U.S. GAAP, we 
recognize the costs and obligations associated with Plan G0 supplemental pension benefits on a “push-down basis,” 
as  we  are  the  recipients  of  the  benefits  of  the  employee  service  for  which  the  supplemental  pension  benefits  are 
made.  The Plan G0 benefit obligation and expenses are accounted for in accordance with SFAS No. 87.  Eventual 
amounts received as reimbursement from the State, if any, are treated as additional paid-in-capital.  As such, Plan 
G0 is considered unfunded for purposes of U.S. GAAP.  See note 23 to our financial statements. 

Assumptions.  Accounting for these pension benefits under the Brazilian Corporate Law Method and U.S. GAAP, 
requires  an  extensive  use  of  assumptions,  including  those  related  to  the  inflation  adjusted  discount  rate,  expected 
return on plan assets, the expected rate of future compensation increases received by our employees, mortality rates, 
and  turnover.    We  review  each  assumption  annually,  with  the  assistance  of  our  actuarial  consultant  who  provides 
guidance in establishing the assumptions.  The assumptions are selected to represent the weighted average expected 
experience over time and may differ in any one year from actual experience due to changes in the capital markets 
and the overall economy, regulatory events, judicial rulings, and higher or lower actual rates of withdrawal, turnover 
or  mortality  among  our  participating  employees.    While  we  believe  that  our  assumptions  used  are  appropriate, 
differences  in  actual  experience  or  changes  in  assumptions  could  affect  the  amount  of  pension  expense  that 
we recognize. 

The present value of our pension obligations was based on a discount rate of 12.32% for 2004, 2005 and 2006.  Our 
pension obligation and expense increases as the discount rate is reduced. 

Our expected return on assets for Plan G1 is determined by evaluating the asset class return expectations with our 
advisors, as well as actual, long-term historical results of our asset returns.  For 2006, we used an expected rate of 
return on assets assumption of 12.06%.  The expected return on assets assumption is based on a targeted allocation 
of  investments in accordance  with the  investment strategies of  the  plans.   We  believe  that  this  targeted  allocation 
will, on average, approximate actual long-term asset allocation. 

Certain Transactions with Controlling Shareholder 

Reimbursement Due from the State.  Reimbursement due from the State for pensions paid represent supplementary 
pensions (Plan G0) that we pay, on behalf of the State, to former employees of the State-owned companies which 
merged to form a company.  These amounts are reimbursed to us by the State, as primary obligor.  However, these 

60 

 
 
amounts have been outstanding for a long period.  We account for these as long-term assets, and we do not reserve 
against such accounts receivable as we expect to recover these amounts and loss is not considered probable. 

Accounts Receivable from the State for Water and Sewage Service Provided.  Certain of these accounts receivable 
have been overdue for a long period and we do not reserve against such accounts receivable as we fully expect to 
recover  these  amounts  and  loss  is  not  considered  probable.    We  have  entered  into  agreements  with  the  state  with 
respect  to  these  accounts  receivable.    For  further  information  on  these  agreements,  see  note  6  to  our  financial 
statements. 

Use of Certain Assets Owned by the State.  We currently use certain reservoirs in the Alto Tietê System and the 
Billings  and  Guarapiranga  reservoirs  which  are  owned  indirectly  by  the  State.    We  currently  do  not  pay  any  fees 
with respect to the use of these reservoirs.  However, we are responsible for maintaining and meeting the operating 
costs of these reservoirs.  If these facilities had not been made available for our use, we would have had to obtain 
water  from  more  distant  sources,  which  would  be  more  costly.    The  State  does  not  incur  operating  costs  on 
our behalf. 

The  arrangement  not  to  pay  any  fees  to  the  State  for  the  use  of  certain  reservoirs  of  the  Alto  Tietê  System  is 
addressed by a number of formal agreements first entered into on March 31, 1992 and on April 24, 1997 and later 
amended  on  March 16,  2000  and  on  November 21,  2001,  respectively.    As  part  of  the  arrangement,  we  agreed  to 
fund  100.0%  of  the  estimated  costs  of  the  1992  agreement  (equal  to  R$27.8 million)  and  75.0%  of  the  1997 
agreement (equal to R$63.4 million) which was already disbursed, and the Government of the State of São Paulo, 
through the State Department of Water and Energy, agreed to fund approximately 25.0% of the estimated costs of 
the  1997  agreement  (equal  to  R$21.1 million),  to  construct  ducts,  tunnels  and  other  facilities  to  interconnect  the 
Tietê  River  with  the  Biritiba  and  Jundiaí  reservoirs  and  other  bodies  of  water  in  exchange  for  our  use  of  the 
reservoirs during a 30-year period.  The amendments to the 1997 agreement increased  our obligations under such 
agreement by R$5.9 million. 

We have the right to draw water and release emissions in the reservoirs in the Alto Tietê system during a 30-year 
period which began in 1997.  We capitalize our expenditures on the facilities we construct.  The project subject to 
the  1992  agreement  was  concluded  and  the  assets  entered  operations  in  1994.    The  project  subject  to  the  1997 
contract became operational in 2002 and is being depreciated on a straight-line basis through 2027. 

The arrangement for use of the Billings and Guarapiranga reservoirs is provided for through a grant issued by the 
Department  of  Water  and  Energy.    We  have  a  right  to  use  these  reservoirs  so  long  as  we  remain  responsible  for 
maintaining and meeting their operating costs.

Year Ended December 31, 2006 Compared to Year Ended December 31, 2005 

Net Revenue from Sales and Services 

Net revenue  from sales and services increased by R$573.9  million, or 11.6%, to R$5,527.3  million in 2006, from 
R$4,953.4 million in 2005. 

Net revenue from sales and services relating to water services in 2006 increased by R$320.8 million, or 11.2%, to 
R$3,177.3 million in 2006, from R$2,856.5 million in 2005.  This increase was principally due to: 

• 

• 

a 2.7% increase in volume of water invoiced in 2006; and 

the effect of the tariff readjustment in 2005 of 9.0%, with a 6.6% impact in 2006, and the tariff 
readjustment in 2006 of 6.7%, with a 1.7% impact in 2006, which altogether had an impact of 8.3%. 

Net  revenue  from  sales  and  services  relating  to  sewage  services  increased  by  R$253.2  million,  or  12.1%,  to 
R$2,350.1 million in 2006, from R$2,096.9 million in 2005.  Volumes of sewage increased by 4.0%, while tariffs 
increased by 9.0%. 

Cost of Sales and Services 

The  cost  of  sales  and  services  increased  by  R$240.4  million,  or  10.1%,  to  R$2,616.8  million  in  2006,  from 
R$2,376.4  million  in  2005.    As  a  percentage  of  net  revenue  from  sales  and  services,  cost  of  sales  and  services 
decreased to 47.3% in 2006 from 48.0% in 2005. 

The increase in overall costs was principally due to the following factors: 

• 

• 

• 

• 

an increase of R$115.5 million, or 13.6%, in payroll expenses and related charges, primarily due to 
annual salary adjustments of 4.63% that came into effect in May 2006.  In addition, the increase was 
due  to  the  provision  of  a  performance-related  bonus,  a  profit  sharing  plan  taking  into  account  an 
adjustment  in  2006  and  the  charges  related  to  payment  of  compensation  in  connection  with  our 
incentive resignation program, totaling an aggregate amount of R$60.2 million.  This increase was 
partially offset by a 2.7% decrease in the number of our employees, or 470 employees, of which 398 
employees  resigned  under  the  incentive  resignation  program.    While  the  number  of  employees 
covered by this line item decreased to 16,978 in 2006 from 17,448 in 2005, productivity increased  
on  a  company-wide  basis  based  on  our  operating  index  of  the  number  of  water  and  sewage 
connections  per  employee,  which  indicated  684  connections  per  employee  in  2006  and  651 
connections per employee in 2005; 

an  increase  of  R$49.4  million,  or  8.6%,  in  depreciation  and  amortization,  principally  due  to  the 
transfer of assets recorded in construction in progress to operating permanent assets, which resulted 
in  higher  depreciation  costs  during  2006.    We  expect  depreciation  costs  to  increase  in  the  next 
periods in the same proportion of the increase in our assets in operation. 

an increase of R$29.0 million, or 9.7%, in outsourced services, principally due to a R$16.2 million 
increase in preventive and corrective maintenance of water and sewage treatment stations and in fees 
related to sludge disposal services, a R$6.8  million in our water loss control program  and a R$6.0 
million in costs related to hiring security companies;  

an  increase  of  R$25.7  million,  or  6.1%,  in  energy  costs,  principally  as  a  consequence  of  (1)  an 
increase in average energy tariffs of 6.7% in the regular energy supply market; the supply of energy 
from this market represented 84% of energy costs incurred by us in 2006; (2) an increase in energy 
consumption due to an increase of 2.7% in water production and of 4.0% in collection and treatment 
of sewage; and (3) a 16.3% increase in average energy tariffs in the “free market,” which represented 
16% of energy costs incurred by us in 2006.  The increase in energy costs was partially mitigated by 

62 

 
 
(1)  the  migration  of  43%  of  our  energy  requirements  to  the  “free  market,”  where  we  can  more 
efficiently negotiate for the supply of energy, which enabled us to save R$4.9 million in energy costs 
in 2006 and also provided us with a R$24.9 million saving with the supply of energy in connection 
with  the  migration  of  43%  of  our  energy  requirements  to  the  “free  market”  in  2006;  (2)  the 
renegotiation  of  energy  supply  agreements  with  municipalities  of  the  São  Paulo  Metropolitan 
Region,  which  enabled  us  to  save  R$0.5  million;  and  (3)  the  ending  of  the  additional  charge  for 
emergency energy capacity in 2005, which enabled us to save R$7.3 million; 

• 

• 

an increase of R$12.5 million, or 11.9%, in materials, principally due to a R$5.6 million increase in 
materials used in the distribution and collections network maintenance, a R$4.6 million increase in 
fuel, expenses in the amount of R$0.9 million related to our obtainment of the International 
Occupational Health and Safety Management System Specification Certification, the OHSAS 18001 
Certification, which is a non-recurrent expense, and a R$1.4 million increase in several other types 
of materials; and 

an increase of R$5.6 million, or 5.7%, in treatment materials, due to a higher volume of treated water 
and collected and treated sewage as a result of the increase in consumption and the increase in the 
price of certain materials.  The average increase in prices of treatment materials was 8.3%, but more 
efficient operating procedures resulted in total costs not increasing to the same extent.  

Gross Profit 

As  a  result  of  the  factors  discussed  above,  gross  profit  in  2006  increased  by  R$333.5  million,  or  12.9%,  to 
R$2,910.5 million in 2006, from R$2,577.0 million in 2005.  As a percentage of net revenue from sales and services, 
gross profit increased to 52.7% in 2006 from 52.0% in 2005. 

Selling Expenses 

Selling  expenses  in  2006  increased  by  R$181.4  million,  or  33.7%,  to  R$719.2  million  in  2006,  from  R$537.8 
million  in  2005.    As  a  percentage  of  net  revenue  from  sales  and  services,  selling  expenses  increased  to  13.0%  in 
2006, from 10.9% in 2005. 

The increase in selling expenses was primarily due to the following factors: 

• 

• 

• 

an  increase  of  R$156.6  million,  or  61.3%,  in  bad  debt  expenses,  net  of  recoveries,  to  R$411.9 
million in 2006 from R$255.3  million in 2005.  Excluding the effects of the adjustment of R$93.8 
million,  which  was  a  result  of  an  analysis  and  conciliation  procedure  related  to  the  accounting 
balance  of  our  accounts  receivable,  the  increase  was  mainly  due  to  the  increase  in  receivables 
following the end of the water usage reduction bonus program in 2004.  For further information on 
our accounts receivable, see note 5 to our financial statements.  The increase was also related to the 
tariff adjustment of 9.0% in August 2005.  

an  increase  of  R$12.3  million,  or  26.3%,  in  general  expenses,  principally  due  to  the  fact  that 
collection tariffs until 2005 were recorded under the line item cost of sales and services and as from 
2006 these expenses started being recorded under the line item selling expenses; and 

an increase of R$16.4  million, or 11.5%, in payroll expenses and related charges, primarily due to 
annual salary adjustments of 4.63% that came into effect in May 2006.  In addition, the increase was 
due  to  the  provision  of  a  performance-related  bonus,  a  profit  sharing  plan  taking  into  account  an 
adjustment  in  2006  and  the  charges  related  to  payment  of  compensation  in  connection  with  our 
incentive resignation program, totaling an aggregate amount of R$10.4 million. 

63 

 
 
 
Administrative Expenses 

Administrative  expenses  for  2006  increased  by  R$37.8  million,  or  10.8%,  to  R$387.4  million  in  2006,  from 
R$349.6 million in 2005.  As a percentage of net revenue from sales and services, administrative expenses decreased 
to 7.0% in 2006, from 7.1% in 2005. 

The increase in administrative expenses primarily reflected: 

• 

• 

• 

an  increase  of  R$30.6  million,  or  34.8%,  in  provisions  for  judicial  proceedings,  resulting  from 
environmental claims as to which losses are probable;  

an increase of R$20.1  million, or 17.9%, in payroll expenses and related charges, primarily due to 
annual salary adjustments of 4.63% that came into effect in May 2006.  In addition, the increase was 
due  to  the  provision  of  a  performance-related  bonus,  a  profit  sharing  plan  taking  into  account  an 
adjustment  in  2006  and  the  charges  related  to  payment  of  compensation  in  connection  with  our 
incentive resignation program, totaling an aggregate amount of R$9.2 million; and 

a decrease of R$14.8 million, or 15.7%, in outsourced services related to a decrease in fees paid to 
external advisers with respect to our debt restructuring in the capital markets.  

Financial Expenses, Net 

Financial  expenses,  net  consist  primarily  of  interest  on  our  indebtedness,  foreign  exchange  losses  (or  gains)  in 
respect  of  our  indebtedness,  offset  partially  by  interest  income  on  cash  and  time  deposits  and  inflation-based 
indexation  accruals,  mainly  relating  to  agreements  entered  into  with  some  customers  to  settle  overdue 
accounts receivable. 

Financial  expenses,  net  in  2006  increased  by  R$116.3  million,  or  26.0%,  to  R$563.3  million  in  2006,  from 
R$447.0 million in 2005.  As a percentage of net revenue from sales and services, financial expenses, net decreased 
to  10.2%  in  2006,  from  9.0%  in  2005.    Financial  expenses  increased  R$127.1  million,  or  22.6%.  The  increase  in 
financial expenses was primarily due to: 

• 

• 

a  decrease  of  R$215.7  million  mainly  in  foreign  exchange  gains,  reflecting  the  effects  of  the 
appreciation of the real against the U.S. dollar.  In 2006, we recorded gains in the amount of R$95.6 
million, resulting from a 9.5% appreciation of the real against the U.S. dollar.  In 2005, we recorded 
gains in the amount of R$311.3 million, resulting from a 13.4% appreciation of the real against the 
U.S. dollar; and 

a  decrease  of  R$10.8  million  in  interest  and  other  charges  related  to  our  real-denominated  debt, 
principally  due  to  (1)  a  R$9.0  million  decrease  in  payment  of  interest  due  to  the  prepayment  of 
debentures with proceeds from our FIDC, which decreased interest rates from 1.1% to 0.7%; (2) new 
issuances of debentures in the end of 2005 and the decrease in payment of interest was reflected in 
our results of 2006. 

The increase in financial expenses, net was partially offset by: 

• 

• 

a decrease of R$79.2 million for monetary adjustments in provisions for judicial proceedings related 
to interest expenses, due to the decrease in amounts provisioned with respect to court deposits; and  

a  decrease  of  R$20.7  million  in  interest  and  other  charges  related  to  our  foreign  currency-
denominated  debt,  principally  due  to  (1)  a  R$42.5  million  decrease  in  payment  of  interest  on 
Eurobonds due to the amortization of the notes due 2005 in July 2005 and the prepayment of part of 
the 12.5% notes due 2008 in November 2006;  we made this prepayment with the proceeds from our 
offering of 7.5% notes due 2016 in the amount of US$140.0 million in November 2006; (2) a R$9.4 
million  in  payment  of  interest  on  the  principal  related  to  the  loan  agreement  entered  into  with  the 

64 

 
 
Inter-American Development Bank and syndicated loans; (3) a R$31.3 million increase in expenses 
with the payment of the premium for note holders who tendered their 12.5% notes due 2008, which 
is a non-recurrent expense. 

Financial income increased by R$10.4 million, or 9.0%, to R$125.9 million in 2006, from R$115.5 million in 2005, 
which was related to interest income from short-term investments. 

As of December 31, 2006, 76.7% of our debt was denominated in reais and 23.3% was denominated in U.S. dollars. 

Income from Operations 

As a result of the factors discussed above, income from operations in 2006 decreased by R$2.0 million, or 0.2%, to 
R$1,240.6 million in 2006, from R$1,242.6 million in 2005. 

Non-Operating Expenses 

Non-operating expenses in 2006 increased by R$25.5 million, or 100.4%, to R$50.9 million, from R$25.4 million in 
2005.  Losses on the disposal of obsolete assets were R$47.8 million in 2006, compared to R$19.1 million in 2005. 

Income Tax and Social Contribution Tax 

Income tax and social contribution tax (including deferred taxes) in 2006 increased by R$59.2 million, or 18.7%, to 
R$375.7  million from R$316.5  million in 2005.  This was primarily due to the increase in taxable income, which 
was R$1,283.5 in 2006, compared to R$1,217.2 million in 2005.  This increase in profits was partially offset by tax 
benefits resulting from the declaration of interest on shareholders’ equity.  This benefit amounted to R$92.1 million 
in  2006,  compared  to  R$118.4  million  in  2005,  over  interest  on  shareholders’  equity  in  the  amounts  of 
R$270.8 million and R$348.2 million, respectively. 

Extraordinary Item 

In  accordance  with  the  requirements  of  the  CVM,  under  CVM  Deliberation  No.  371/2000,  we  have  elected  to 
recognize the actuarial transition liability of R$266.1 million calculated as of December 31, 2001 with respect to our 
defined-benefit  pension  plan  (Plan  G1)  on  a  straight-line  basis  against  earnings  over  the  five-year  period  ending 
December 31, 2006. 

As  permitted,  the  expense  is  recorded  as  an  extraordinary  item  of  R$35.1  million,  net  of  income  tax,  of 
R$18.1 million, for both 2006 and 2005. 

Net Income 

As  a  result  of  the  factors  discussed  above,  net  income  decreased  by  10.0%,  to  R$778.9  million  in  2006,  from 
R$865.6  million  in  2005.    Excluding  the  effects  of  the  adjustment  of  R$93.8  million,  which  was  a  result  of  an 
analysis  and  conciliation  procedure  related  to  the  accounting  balance  of  our  accounts  receivable,  our  net  income 
would  have  increased  by  R$7.0  million.    The  bulk  of  this  increase  derived  from  profits  from  operations,  which 
recorded  a  significant  growth  of  40.3%,  and  the  8.7%  appreciation  of  the  real  contributed  to  the  balance  of  the 
increase. 

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004 

Net Revenue from Sales and Services 

Net revenue  from sales and services increased by R$556.3  million, or 12.7%, to R$4,953.4  million in 2005, from 
R$4,397.1 million in 2004. 

65 

 
 
 
Net revenue from sales and services relating to water services in 2005 increased by R$315.5 million, or 12.4%, to 
R$2,856.5 million in 2005, from R$2,541.0 million in 2004.  This increase was principally due to: 

• 

• 

• 

a 3.9% increase in the volume of water distributed and invoiced in 2005; 

the effect of the tariff readjustment in 2004 of 6.78% and the impact, from August 2005, of a tariff 
increase of 2.38%, which together had an impact of 9.32%; and 

the migration of some households from lower to higher tariff categories due to their increased water 
usage, which accounted for an increase of 1.1% in revenues. 

Net revenue from sales and services relating to sewage services increased by R$240.8 million, or 13%, to R$2,096.9 
million in 2005, from R$1,856.1 million in 2004.  Volumes of sewage increased by 5.0%, while tariffs increased by 
9.0%. 

Cost of Sales and Services 

The cost of sales and services increased by R$123.0 million, or 5.5%, to R$2,376.4 million in 2005, from R$2,253.4 
million  in  2004.    As  a  percentage  of  net  revenue  from  sales  and  services,  cost  of  sales  and  services  decreased  to 
48.0% in 2005 from 51.2% in 2004. 

The increase in overall costs was principally due to the following factors: 

• 

• 

• 

• 

• 

an  increase  of  R$44.9  million,  or  5.6%,  in  payroll  expenses  and  related  charges,  primarily  due  to 
annual  salary  adjustments  of  7.9%  that  came  into  effect  in  May  2005,  partially  offset  by  a  1.6% 
decrease in the number of our employees.  While the number of employees covered by this line item 
decreased to 17,448 in 2005 from 17,735 in 2004, productivity increased on a company-wide basis 
based on our operating index of the number of water and sewage connections per employee, which 
indicated 651 connections per employee in 2005 and 626 connections per employee in 2004; 

an increase of R$37.1 million, or 14.2%, in outsourced services, principally due to a R$17.0 million 
increase  related  to  maintenance  of  domestic  connections,  a  R$10.0 million  increase  in  distribution 
and  collections  network  maintenance,  a  R$3.6  million  increase  for  technical  and  professional  fees 
primarily  related  to  execution  of  the  plan  for  final  sludge  disposal  in  the  Tietê  River  clean-up 
program, and a R$2.5 million increase in costs related to hiring security companies; 

an  increase  of  R$24.4  million,  or  6.1%,  in  energy  costs,  principally  as  a  consequence  of  a  14.1% 
increase  in average  tariffs,  and  an  increase of  2.2%  in energy consumption due  to  increased  water 
production.    This  increase  was  partially  mitigated  by  the  migration  of  43%  of  our  energy 
requirements to the “free market,” where we can more efficiently negotiate for the supply of energy, 
by  the  implementation  of  plans  to  improve  energy  efficiency,  and  by  the  ending  of  the  additional 
charge for emergency energy capacity, which was gradually stepped to zero by the end of 2005; 

an increase of R$20.8 million, or 24.6%, in materials, principally due to an increase of R$8.1 million 
in materials used in the distribution and collections network maintenance, a R$4.4 million increase 
in materials for domestic connection maintenance, an increase of R$2.8 million in fuel expenses and 
a R$1.1 million increase in several other types of materials; and 

an  increase  of  R$7.3  million,  or  8.0%,  in  treatment  materials,  due  to  the  higher  volume  of  water 
treated and an increase in the price of certain materials.  The average increase in prices of treatment 
materials was 11.6%, but more efficient operating procedures resulted in total costs not increasing to 
the  same  extent.    Additionally,  lower  outbreaks  of  algae  efflorescence  resulted  in  less  expenses, 
amounting to R$2.7 million, in costs for coal to treat algae. 

66 

 
 
Gross Profit 

As  a  result  of  the  factors  discussed  above,  gross  profit  in  2005  increased  by  R$433.3  million,  or  20.2%,  to 
R$2,577.0 million in 2005, from R$2,143.7 million in 2004.  As a percentage of net revenue from sales and services, 
gross profit increased to 52.0% in 2005 from 48.8% in 2004. 

Selling Expenses 

Selling expenses in 2005 increased by R$35.3 million, or 7.0%, to R$537.8 million in 2005, from R$502.5 million 
in 2004.  As a percentage of net revenue from sales and services, selling expenses decreased to 10.9% in 2005, from 
11.4% in 2004. 

The increase in selling expenses was primarily due to the following factors: 

• 

• 

• 

an increase of R$15.4 million, or 23.0%, in expenses for outsourced services, principally an increase 
of R$8.7 in fees for professional and technical services in connection  with the study related to the 
implementation of a new tariff policy, as discussed above, an increase in costs for meter reading and 
billing in the amount of R$4.9 million, and a R$1.6 million increase in costs relating to other selling 
expenses; 

an increase of R$13.7 million, or 5.7%, in bad debt expenses, net of recoveries.  Bad debts of R$79.8 
million were partially offset by recoveries of R$66.1 million, resulting from more efficient recovery 
procedures; and 

an  increase  of  R$4.5  million,  or  3.3%,  in  payroll  expenses  and  related  charges  due  to  the  annual 
salary  adjustment  of  7.9%,  as  discussed  above,  the  effect  of  which  was  partially  mitigated  by  a 
reduction in the number of our employees. 

These increases were offset by: 

• 

a  reduction  of  1.6%  in  the  number  of  employees  with  a  commensurate  increase  in  productivity; 
efficiencies adopted in order to reduce electrical costs such as the implementation of an efficiencies 
program and  the  migration of  43%  of our  energy  consumption to the  “free  market,”  where we are 
able to pay less for energy; and more efficient use of water treatment materials. 

Administrative Expenses 

Administrative  expenses  for  2005  increased  by  R$36.0  million,  or  11.5%,  to  R$349.6  million  in  2005,  from 
R$313.6 million  in  2004.    As  a  percentage  of  net  revenue  from  sales  and  services,  administrative  expenses  were 
approximately 7.1% in 2005 and in 2004. 

The increase in administrative expenses primarily reflected: 

• 

• 

• 

• 

an increase of R$27.1 million, or 44.5%, in provisions for judicial proceedings, resulting from new 
claims as to which losses are probable;  

an  increase  of  R$3.6  million,  or  14.2%,  in  tax  expenses,  principally  for  CPMF,  generated  by 
payment of debts in 2005;  

an  increase  of  R$3.1  million,  or  17.9%,  in  depreciation  and  amortization,  principally  related  to 
amortization of newly completed assets coming on line; and 

an increase of R$2.6 million, or 2.4%, in payroll expenses, the effect of which was mitigated in part 
by a reduction in the number of employees. 

67 

 
 
Financial Expenses, Net 

Financial  expenses,  net  consist  primarily  of  interest  on  our  indebtedness,  foreign  exchange  losses  (or  gains)  in 
respect  of  our  indebtedness,  offset  partially  by  interest  income  on  cash  and  time  deposits  and  inflation-based 
indexation  accruals,  mainly  relating  to  agreements  entered  into  with  some  customers  to  settle  overdue 
accounts receivable. 

Financial  expenses,  net  in  2005  decreased  by  R$56.7  million,  or  11.3%,  to  R$447.0  million  in  2005,  from 
R$503.7 million in 2004.  As a percentage of net revenue from sales and services, financial expenses, net decreased 
to 9.0% in 2005, from 11.5% in 2004.  Financial expenses decreased R$79.9 million, or 12.5%. 

The decrease in financial expenses was primarily due to: 

• 

• 

an  increase  of  R$147.7  million  mainly  in  foreign  exchange  gains,  reflecting  the  effects  of  the 
appreciation  of  the  real  against  the  U.S.  dollar.    In  2005,  we  recorded  gains  of  R$312.1  million, 
resulting  from  a  13.4%  appreciation  of  the  real.    In  2004,  we  recorded  gains  of  R$179.7  million, 
resulting  from  a  8.8%  appreciation  of  the  real.    The  amount  of  debt  denominated  in  dollars 
decreased by 32.3%, to US$670 million in 2005, from US$990 million in 2004; and 

a decrease of R$77.1 million in interest and other charges related to foreign currency-denominated 
debt  due  to  the  decrease  of  32.3%  in  the  amount  of  our  U.S.  dollar-denominated  debt  and  to  the 
appreciation of the real against the foreign currency in which our non-real debt is denominated. 

The decrease in financial expenses was offset by: 

• 

• 

• 

an increase of $77.6 million in interest and other charges related to our real-denominated debt due to 
our  6th,  7th,  and  8th  issuances  of  debentures  in  September  2004  and  March  and  June  2005, 
respectively.    As  of  December  31,  2005  and  2004,  the  balance  of  outstanding  debentures  was 
R$2,009.3 million and R$1,254.8 million, respectively; 

an increase of R$38.0 million for monetary adjustments in provisions for judicial proceedings related 
to interest expenses, due to the increase in amounts provisioned with respect to suppliers and final 
consumer claims; and 

an  increase  of  R$33.2  million  for  income  tax  on  remittances  abroad,  due  to  recoveries  on  such 
amounts that were recorded in 2004 and did not recur in 2005. 

Financial  income  decreased  by  R$23.2  million,  or  16.8%,  to  R$114.7  million  in  2005,  from  R$137.9 million  in 
2004, which was related to a decrease of R$26.3 million in income from monetary variations, to R$34.0 million in 
2005, from R$60.3 million in 2004, due to indexation adjustments. 

As of December 31, 2005, 76.4% of our debt was denominated in reais and 23.6% was denominated in U.S. dollars. 

Income from Operations 

As a result of the factors discussed above, income from operations in 2005 increased by R$418.7 million, or 50.8%, 
to R$1,242.6 million in 2005, from R$823.9 million in 2004. 

Non-Operating Expenses 

Non-operating expenses in 2005 decreased by R$8.5 million, or 25.1%, to R$25.4 million, from R$33.9 million in 
2004.  Losses on disposal of obsolete assets were R$19.1 million in 2005, compared to R$34.4 million in 2004. 

68 

 
 
Income Tax and Social Contribution Tax 

Income tax and social contribution tax (including deferred taxes) in 2005 increased by R$74.6 million, or 30.8%, to 
R$316.5  million from R$241.9  million in 2004.  This was primarily due to the increase in taxable income, which 
was R$1,217.2 in 2005, compared to R$790.0 million in 2004.  This increase in profits was partially offset by tax 
benefits resulting from the declaration of interest on shareholders’ equity.  This benefit amounted to R$118.4 million 
in  2005,  compared  to  R$52.0  million  in  2004,  over  interest  on  shareholders’  equity  in  the  amounts  of 
R$348.2 million and R$152.9 million, respectively. 

Extraordinary Item 

In  accordance  with  the  requirements  of  the  CVM,  under  CVM  Deliberation  No.  371/2000,  we  have  elected  to 
recognize the actuarial transition liability of R$266.1 million calculated as of December 31, 2001 with respect to our 
defined-benefit  pension  plan  (Plan  G1)  on  a  straight-line  basis  against  earnings  over  the  five-year  period  ending 
December 31, 2006. 

As  permitted,  the  expense  is  recorded  as  an  extraordinary  item  of  R$35.1  million,  net  of  income  tax,  of 
R$18.1 million, for both 2005 and 2004. 

Net Income 

As  a  result  of  the  factors  discussed  above,  net  income  increased  by  68.8%,  to  R$865.6  million  in  2005,  from 
R$513.0  million  in  2004.    The  bulk  of  this  increase  derived  from  profits  from  operations,  which  recorded  a 
significant growth of 66.2%, and the 11.8% appreciation of the real contributed to the balance of the increase. 

U.S. GAAP RECONCILIATION 

Our net income in accordance with the Brazilian Corporate Law Method was R$513.0 million, R$865.6 million and 
R$778.9 million in 2004, 2005 and 2006, respectively.  Under U.S. GAAP, we would have reported net income of 
R$417.5 million, R$791.2 million and R$622.5 million in 2004, 2005 and 2006.  

Our  shareholders’  equity  in  accordance  with  the  Brazilian  Corporate  Law  Method  totaled  R$7,951.6  million, 
R$8,482.5  million  and  R$9,018.5  million  as  of  December  31,  2004,  2005  and  2006,  respectively.    Under  U.S. 
GAAP,  we  would  have  reported  shareholders’  equity  of  R$6,364.8  million,  R$6,821.4  million  and  R$7,298.2 
million as of December 31, 2004, 2005 and 2006, respectively.  

The principal differences between the Brazilian Corporate Law Method and U.S. GAAP that affect our net income 
in  2004,  2005  and  2006,  as  well  as  shareholders’  equity  as  of  December  31,  2004,  2005  and  2006,  relate  to  the 
treatment of the following items: 

• 

• 

• 

additional  inflation  restatements  and  related  depreciation  which  would  be  mandated  by  U.S. 
GAAP  (but  which  are  not  permitted  under  the  Brazilian  Corporate  Law  Method)  for  1996  and 
1997 in recognition of Brazil’s status as a highly inflationary country in those years; 

revaluations  of  property,  plant  and  equipment  recorded  in  1990  and  1991  under  the  Brazilian 
Corporate Law Method, which would be reversed and partially replaced by supplemental inflation 
restatements  based  upon  a  general  price  index  (IGP-M)  for  periods  prior  to  1990  under  U.S. 
GAAP; 

pension  plan  (Plan  G0)  payments  and  other  employee  benefits  for  former  employees  of  our 
predecessor  companies  which  are  obligations  of  the  State  and  which  are  not  treated  as  our 
expenses under the Brazilian Corporate Law Method, but which would be required to be treated as 
our expense on an actuarial basis under U.S. GAAP; 

69 

 
 
• 

• 

pension  plan  (Plan  G1)  expenses  which,  through  December  31,  2001,  were  recognized  on  an 
accrual basis only to the extent of required contributions for the relevant year or financial period 
under the Brazilian Corporate Law Method, but which would be required to be fully recorded on 
an actuarial basis under U.S. GAAP.  Since January 1, 2002 under the Brazilian Corporate Law 
Method,  recognition  on  an  actuarial  basis  is  required.    There  are  some  differences  as  compared 
with U.S. GAAP, basically regarding the calculation method, amortization period and recognition 
rules, resulting in different pension cost obligation; and 

additional  accounting  items,  including,  among  others,  capitalized  interest,  expensing  of  deferred 
charges, deferral of certain debt issue costs, and related deferred taxes. 

See note 23 to our financial statements for a description of these differences as they relate to us and a reconciliation 
of net income and total shareholders’ equity from the Brazilian Corporate Law Method to U.S. GAAP.  

5.B. Liquidity and Capital Resources 

Capital Sources 

In  order  to  satisfy  our  liquidity  and  capital  requirements,  we  have  primarily  relied  on  cash  provided  by  operating 
activities,  borrowings  from  Brazilian  Federal  and  State  governmental  financial  institutions,  and  financing  from 
multilateral organizations and from domestic and international capital markets.  As of December 31, 2006, we had 
R$328.2  million  of  cash  and  cash  equivalents.    Outstanding  short-term  debt  was  R$852.5  million  as  of 
December 31,  2006,  of  which  R$120.1  million  was  denominated  in  foreign  currency.    Long-term  debt  was 
R$5,474.3 million, of which R$1,352.6 million consisted of foreign currency-denominated obligations.  We believe 
that we have sufficient sources of liquidity and capital to meet our liquidity and capital requirements for the next few 
years, in light of our current financial position and our expected cash generated by operating activities. 

Cash  Provided  by  Operating  Activities.    Cash  provided  by  operating  activities  is,  and  we  anticipate  that  it  will 
continue to be, the single largest source of our liquidity and capital resources in future years and financial periods.  
Our cash generated by operating activities was R$1,441.1 million, R$1,737.6 million and R$2,020.8 million in 2004, 
2005 and 2006. 

We have overdue accounts receivable  from the State and from  the  municipalities to  which we provide water on a 
wholesale  basis.    For  more  information,  see  “Item  7.B.    Major  Shareholders  and  Related  Party  Transactions—
Related Party Transactions.” 

Debt Financing.  As of December 31, 2006, we had R$5,474.3 million in long-term debt outstanding (excluding the 
current portion of long-term debt), of which R$1,352.6 million consisted of foreign currency-denominated long-term 
debt.  We had outstanding short-term debt of approximately R$852.5 million as of December 31, 2006, representing 
the current portion of our long-term debt.   

As  of  December  31,  2006,  approximately  R$120.1  million  of  this  short-term  debt  was  denominated  in  foreign 
currencies.    Substantially  all  of  our  foreign  currency-denominated  debt  of  R$1,472.8  million  as  of  December  31, 
2006 was denominated in U.S. dollars or in baskets of foreign currencies.   

This debt consisted principally of: 

(1)  R$931.9  million  (US$435.9  million)  in  U.S.  dollar  denominated  loans  from  the  Inter-American 
Development  Bank.    Under  these  loans,  payments  of  principal  are  made  in  semi-annual  installments  with  final 
maturity  in  July  2025.    The  principal  amount  is  adjusted  semi-annually  for  the  variation  in  a  basket  of  foreign 
currencies  and  accrues  interest  at  a  rate  varying  from  3.00%  to  7.70%.    We  have  pledged  part  of  our  receivables 
from our sales and services up to the amount due as collateral.  For further information on the terms of these loan 
agreements,  see  “Item  4.A.    History  and  Development  of  the  Company—Capital  Expenditure  Program—Tietê 
Project.” 

70 

 
 
(2) R$209.6  million (US$98.1  million) in aggregate principal amount of our 12% notes due 2008 sold in 
the  international  capital  markets  in  June  2003  and  R$299.3  million  (US$140.0  million)  in  the  aggregate  principal 
amount of our 7.5% notes due 2016 sold to the international capital markets in November 2006. 

(3) R$4.8 million (US$2.2 million) in U.S. dollar loans from the World Bank.  Under the loan agreement, 
amortizations  of  principal  are  made  in  20  semi-annual  installments  every  month  of  April  and  October,  with  final 
maturity in April 2007 (the 20th installment was paid on April 15, 2007).  The principal amount is adjusted semi-
annually  for  the  variation  in  the  basket  of  foreign  currencies  and  accrues  interest  at  a  rate  of  5.15%.    We  have 
granted as collateral some of our properties.  For more information on the properties pledged, see “Item 4.A.  History 
and  Development  of  the  Company—Capital  Expenditure  Program—Tietê  Project”  and  “Item  4.D.    History  and 
Development  of  the  Company—Property,  Plant  and  Equipment.”    For  a  detailed  discussion  on  the  terms  and 
guarantees  of  this  loan  agreement,  see  “Item  7.B.    Major  Shareholders  and  Related  Party  Transactions—Related 
Party Transactions—Government Guarantees on Financing.” 

Our borrowings from multilateral institutions, such as the World Bank and the Inter-American Development Bank, 
have in the past been, and in the future are likely to be, guaranteed by the Government of the State or the Federal 
Government.  We do not pay fees for these guarantees.  Under some of the loan agreements with the Inter-American 
Development Bank, we have granted a guarantee (contra garantia) to the Federal Government.   

Our  outstanding  domestic  debt  was  approximately  R$4,854.0  million  as  of  December  31,  2006  and  consisted 
primarily of real-denominated loans from Federal and State-owned banks, in particular, Banco do Brasil S.A., Caixa 
Econômica  Federal  and  the  Brazilian  National  Bank  for  Economic  and  Social  Development  (Banco  Nacional  de 
Desenvolvimento  Econômico  e  Social),  or  BNDES,  as  well  as  debentures  issued  in  April  2001,  April  2002, 
September 2004 and March and June 2005.   

The following summarizes our principal borrowings from Federal and State-owned banks: 

(1)  In  March  1994,  we  entered  into  a  loan  agreement  with  Banco  do  Brasil  S.A..    Amortizations  of 
principal  amount  are  made  in  240  successive  monthly  installments,  with  final  maturity  in  2014.    The  principal 
amount accrues interest at the daily government interest rate plus 8.50% per annum and monetary adjustment.  

(2)  We  have  entered  into  several  line  of  credit  agreements  with  Caixa  Econômica  Federal,  pursuant  to 
which  amortizations  of  principal  are  made  paid  in  120  or  180  months  in  monthly  installments  after  30  days 
following  a  grace  period,  which  varies  from  14  to  36  months  from  the  date  of  the  first  draw-down.    The  final 
maturity is 2022.  The principal amount accrues interest at a rate varying from 5.00% to 9.50%. 

(3) In August 2002, we entered into a line of credit agreement with BNDES.  The final maturity date will 
be in February 2013.  The principal amount accrues interest at the long-term rate fixed by the Federal Government 
(Taxa  de  Juros de Longo  Prazo),  or TJLP,  limited to 6%, plus  3.00% per annum.   If  the TJLP  exceeds  6%, such 
excess will be added to the principal amount payable at maturity. 

In addition, we entered into a credit agreement on August 6, 2004 with the JBIC for the financing of the 
Environmental  Recovery  Program  for  the  Santos  Metropolitan  Region,  which  was  guaranteed  by  the  Federal 
Government for an aggregate principal amount of ¥21,320 million (R$382.8 million).  The disbursements began in 
January 2006.  As of December 31, 2006, the total amount disbursed was R$11.7 million.  In addition to the amount 
received under the JBIC credit agreement, we intend to invest up to R$355.0  million in this program.  Under this 
financing  agreement,  amortizations  are  made  in  semi-annual  installments  in  August  and  February,  with  final 
maturity 2029.  This obligation is guaranteed by the Federal Government.  For further information on the terms and 
guarantees  of  this  financing  agreement,  see  “Item  7.B.    Major  Shareholders  and  Related  Party  Transactions—
Related  Party  Transactions—Government  Guarantees  of  Financing”  and  “Item  4.A.    History  and  Development  of 
the  Company—Capital  Expenditure  Program—Capital  Expenditure  Program—Environmental  Recovery  Program 
for the Santos Metropolitan Region.”   

In addition, we are currently negotiating with BNDES and Caixa Econômica Federal for additional loans to finance 
portions of our capital expenditure program.

With  respect  to  the  debentures  issued  on  September  17,  2004,  we  filed  a  securities  shelf  program  with  the  CVM 
through  which  we  were  able  to  offer  non-convertible  debentures  in  the  aggregate  amount  of  R$1.5  billion.    We 
issued the total amount available under this shelf program by July 1995.  As part of the program: 

(1)  We  issued  R$600.0  million  in  aggregate  principal  amount  of  debentures  in  September  2004  (our  6th 
issuance), offered in three separate  series.   The debentures  of  the  first, second  and  third series will  mature within 
three,  five and six years after issuance,  respectively.   The debentures of  the  first series in the amount  of R$231.8 
million bear interest at the interbank deposit rate (CDI) plus 1.75% per year, and the debentures of the second series 
in the amount of R$188.3 million, and of the third series, in the amount of R$179.9 million, bear interest at rates of 
IGP-M index plus 11.0% per year. 

(2)  We  also  issued  R$300.0 million  in  aggregate  principal  amount  of  debentures  in  March  2005  (our  7th 
issuance), offered in two series.  The debentures of the first and second series will mature within four and five years, 
respectively, after issuance.  The debentures of the first series, in the total amount of R$200.0 million, bear interest 
at the interbank deposit rate (CDI) plus 1.5% per year, and the debentures of the second series, in the total amount of 
R$100.0 million, bear interest at the rate of IGP-M index plus 10.8% per year. 

(3)  We  also  issued  R$700.0  million  in  aggregate  principal  amount  of  debentures  in  June  2005  (our  8th 
issuance), offered in two series.  The debentures of the first and second series will mature within four and six years, 
respectively, after issuance.  The debentures of the first series, in the total amount of R$350.0 million, bear interest 
at the interbank deposit rate (CDI) plus 1.5% per year, and the debentures of the second series, in the total amount of 
R$350.0 million, bear interest at the rate of IGP-M index plus 10.75% per year. 

All  of  our  real-denominated  debt  is  indexed  to  take  into  account  the  effects  of  inflation.    Most  of  our  real-
denominated  debt  provides  for  inflation-based  increases  in  their  respective  principal  amounts;  the  increases  are 
determined by reference to the daily government interest rate (Taxa Referencial) plus an agreed margin. 

Furthermore, in March  2006,  a securitization  fund  (Fundo  de  Direitos Creditórios)  was created having our  future 
account  receivables  as  its  underlying  assets.    On  March  23,  2006,  the  fund  issued  senior  and  junior  quotas  to 
investors  in  Brazil  with  a  value  per  unit  of  R$500,000.00.    The  senior  quotas  will  be  amortized  in  54  monthly 
installments.  The fund is designed to have a return to investors corresponding to 100% of the interbank deposit rate 
(CDI) variation, plus a fixed interest rate of 0.7% per annum.  We subscribed and paid for and maintain in a deposit 
account 26 junior, or subordinated, quotas of this fund in the total amount of R$13.0 million. 

In March 2006, the fund advanced to us revenues derived from the provision of  water and sewage services in the 
amount of R$250.0 million, representing a portion of the payments due under the underlying receivables during a 
five-year  period.    We  retain  the  right  to  receive  the  balance  of  additional  payments  accounting  for  the  remaining 
portion  of  the  receivables,  provided  that  no  event  of  default  under  the  by-laws  of  the  fund  has  occurred  or  is 
continuing.  Once payments to the fund are made in full, which is expected to happen five years after the creation of 
the fund, we will be entitled to all payments received under the underlying receivables.  The fund manager is Caixa 
Econômica Federal.  See note 10 to our financial statements.  

The  following  table sets  forth information on our outstanding debt  as of  December  31,  2006.   See  note 10  to  our

(1)  UPR  stands  for  Standard  Reference  Unit  (Unidade  Padrão  Referência)  and  is  equal  to  the  daily  government  interest  rate  (Taxa 
Referencial—TR), which was 0,152% per month as of December 31, 2006; CDI stands for Interbank Deposit Rate (Certificado de Depósitos 
Interbancários), which was 13.17% per annum as of December 31, 2006; IGP-M stands for Índice Geral de Preços a Mercado, which was 
3.9% per annum as of December 31, 2006; TJLP stands for Long-term Rate Fixed by the Federal Government on a quarterly basis (Taxa de 
Juros a Longo Prazo), which was 6.8% per annum as of December 31, 2006. 

(2)  Agreements  to  provide  up  to  approximately  R$474.7  million  (unaudited)  in  financing  for  our  capital  expenditure  program  until  final 

maturity.  We have pledged amounts in certain bank accounts as collateral for these loans. 

Financial  Covenants.    We  are  subject  to  financial  covenants  under  the  agreements  evidencing  or  governing  our 
outstanding indebtedness.   

With respect to our indebtedness denominated in U.S. dollars or in baskets of foreign currencies, we are subject to 
financial covenants, including but not limited to those set forth in the loan agreements entered into with the Inter-
American  Development  Bank  and  the  World  Bank.    Each  of  these  agreements  contains,  among  other  provisions, 
limitations on our ability to incur debt.  The indenture relating to the 7.5% notes due 2016 is the most stringent of 
these debt agreements.  This indenture prohibits, subject to some exceptions, the incurrence of additional debt in the 
event that (1) the ratio of Adjusted Total Debt to Adjusted EBITDA (as defined in the related indenture) is greater 
than  3.65x  or  (2) the  Debt  Service  Coverage  Ratio  (as  defined  in  the  indenture)  is  less  than  2.35x.    We  do  not 
believe  that  these  covenants  will  impose  constraints  on  our  ability  to  finance  our  capital  expenditure  program  or, 
more generally, to develop our business and enhance our financial performance.    

In addition, with respect to our outstanding domestic debt, we entered into a financing agreement with the Federal 
Government and Banco do Brasil S.A. and also into several credit agreements with Caixa Econômica Federal that do 
not contain material financial covenants.  Under our credit agreement with BNDES we are required to keep (1) an 
EBITDA/net operational income ratio equal to or higher than 38%, (2) an asset/short-term liability (excluding the 
short term portion of long-term liabilities) ratio higher than 1.0, (3) total connections (water and sewage)/employees 
ratio  equal  to  or  higher  than  520,  (4)  EBITDA/debt  service  equal  to  or  higher  than  1.5  and  (v)  a  shareholders’ 
equity/total debt ratio equal to or higher than 0.8.  

With respect to our debentures, the 4th and the 5th issuances contain no material financial covenants and the 6th, 7th 
and 8th issuances require us to maintain a current debt ratio higher than 1.0:1.0 and an EBITDA/expenditures ratio 
equal to or higher than 1.5:1.0. 

Brazilian  regulations  provide  that  a  state-owned  company,  such  as  us,  must  use  the  proceeds  of  “external  credit 
operations”  (i.e.,  foreign  currency  borrowings),  subject  to  some  exceptions,  exclusively  to  refinance  outstanding 
financial obligations.  Until so used, these proceeds must be deposited as directed by the Central Bank.  The deposit 

73 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
requirement  does  not  apply  in  the  case  of  import  financing  and  financing  transactions  involving  multilateral  and 
official organizations, such as the JBIC, the World Bank and the Inter-American Development Bank. 

Capital Requirements 

We  have,  and  expect  to  continue  to  have,  substantial  liquidity  and  capital  resource  requirements.    These 
requirements include debt-service obligations, capital expenditures to maintain, improve and expand our water and 
sewage systems, payment of pension plan and other employee benefits, including pension plan payments to certain 
of our former employees on behalf of the State, and dividend payments and other distributions to our shareholders, 
including the State. 

Debt-Service and Other Contractual Obligations.  Our debt service obligations and other contractual obligations as 
of December 31, 2006 were as follows:

We believe that we can meet the maturity schedule through a combination of funds generated by operations, the net 
proceeds  of  new  issuances  of  debt  securities  in  the  Brazilian  and  international  capital  markets  and  additional 
borrowings  from  domestic and  foreign  lenders.   Our  borrowings are  not affected by  seasonality.   For information 
concerning the current interest rates borne by our outstanding indebtedness, see note 10 to our financial statements. 

Capital Expenditures.  Historically, our capital expenditures have been  significantly financed with resources from 
international  and  national  multilateral  agencies  and  development  banks.    We  generally  include  in  our  capital 
expenditure program for the following year the amount of investment that was not realized in the previous year.  In 
2003 and 2004, our cash disbursements for purchases of property, plant and equipment under our capital expenditure 
program totaled R$641.3 million and R$670.3 million, respectively.  In 2005, we planned to invest approximately 
R$758.0  million (unaudited) under our capital expenditure program, but effectively invested R$660.4  million. We 
have  budgeted investments  in  the  amount  of  approximately  R$5.87  billion  from  2007  through 2010, of  which  we 
expect to spend R$960.0 million in 2007.  As of December 31, 2006, we had invested R$904.9 million under our 
capital expenditure program.  

Pension  Plan  Payments  and  Employee  Benefits.    We  have  been  making  State-mandated  special  retirement  and 
pension payments to certain former employees who were employed by our predecessor entities prior to May 1974.  
These special payments totaled R$101.7 million in 2006, R$96.4 million in 2005 and R$85.3 million in 2004.  The 
State  is  required  to  reimburse  us  for  these  amounts,  but  has  not  been  paying  us  on  a  timely  basis.    The  State’s 
obligation to us for these amounts is recorded under receivables from shareholder on the balance sheet and totaled 
R$774.5  million  as  of  December  31,  2006.    As  of  December  31,  2004  and  2005  these  receivables  had  reached 
R$576.3  million and R$672.7  million, respectively, and they were classified as non-current assets in our financial 
statements.  The special payments to former employees made by us are not reflected in our statement of operations, 
but nonetheless represent a significant component of our liquidity requirements.  Although we have had discussions 
with the State regarding more timely reimbursement for the special payments to former employees, we cannot assure 
you as to when or whether such payments will be made by the State.  We may continue to be held responsible for 
these  special  payments  to  former  employees,  irrespective  of  whether  the  State  reimburses  us  or  not.    For  further 
information on State-mandated special retirement and pension payments  made by us to certain former employees,

Tax Financing Agreements.  We did not make payments in respect of certain Brazilian federal income tax and social 
contribution  liabilities  during  the  period  from  1991  to  mid-1996  mainly  because  we  were  contesting  certain 
assessments  by  the  federal  tax  authorities  and,  in  the  case  of  1993  and  1994,  because  we  did  not  have  sufficient 
funds  to  meet  all  of  our  then  existing  liquidity  and  capital  resources  requirements.    Under  the  Programa  de 
Recuperacão Fiscal—REFIS tax recovery program, we entered into an agreement with the Brazilian tax authorities 
regarding these tax obligations and have agreed to make payments on them in monthly installments ending in 2005.  
We were also required to pay interest on the unpaid balance of this tax liability.  However, in July 2003, we included 
the  amounts  due  under  the  REFIS  program  in  the  PAES  program,  which  is  an  alternative  payment  plan  for  taxes 
owed.    In  accordance  with  this  settlement  agreement,  we  are  paying  amounts  due,  of  approximately  R$317.0 
million, in 120 monthly installments, from July 2003.  See note 12 to our financial statements.  Payments in respect 
of  this  aggregate  tax  liability  continue  to  constitute  a  liquidity  and  capital  resource  requirement  that  must  be 
satisfied. 

Dividend  Distributions.    We  are  required  by  our  by-laws  to  make  dividend  distributions,  which  can  be  made  as 
payments  of  interest  on  shareholders’  equity  to  our  shareholders  in  an  amount  equal  to  not  less  than  25%  of  the 
amounts available for distribution.  The aggregate amount of distributions we made for 2004, 2005 and 2006 were 
R$152.9 million, R$348.2 million and R$270.8 million, respectively. 

On  April  28,  2005,  our  board  of  directors  approved  the  payment  of  dividends,  in  the  form  of  interest  on 
shareholders’  equity,  in  the  amount  of  R$38.2  million,  to  be  paid  within  60  days  after  our  2006  shareholders’ 
meeting  to  shareholders  of  record  as  of  May  9,  2005.    On  June  23,  2005,  our  board  of  directors  approved  the 
payment of dividends, in the form of interest on shareholders’ equity, in the amount of R$66.8 million, to be paid 
within 60 days after our 2006 shareholders’ meeting to shareholders of record as of July 6, 2005.  On October 20, 
2005, our board of directors approved the payment of dividends, in the form of interest on shareholders’ equity, in 
the  amount  of  R$85.2  million,  to  be  paid  within  60  days  after  our  2006  shareholders’  meeting  to  shareholders  of 
record as of November 3, 2005.  On December 15, 2005, our board of directors approved the payment of dividends 
in the form of interest on shareholders’ equity in the amount of R$158.1 million, to be paid within 60 days of our 
2006  shareholders’  meeting  to  shareholders  of  record  as  of  December  28,  2005.    The  payments  of  interest  on 
shareholders’ equity declared in 2006 began being made on June 29, 2007.  

On  April  20  and  December  14,  2006,  our  board  of  directors  approved  the  payment  of  dividends,  in  the  form  of 
interest on shareholders’ equity, in the amount of R$129.6 million and R$141.2 million, respectively, to be paid on 
June 29, 2007.   

As of December 31, 2006, our dividends payable to the State, due from 2004 through 2005, were in the amount of 
R$260.2 million, with an additional R$136.1 million related to 2006 due beginning in June 2007.  We are currently 
unable  to  determine  the amount, if any,  of the portion of  these  declared  dividends  that  the  State  will  apply to  the 
current and future accounts receivable owed to us by the State or its controlled entities.     

Interest on Shareholders’ Equity 

Brazilian corporations are permitted to distribute dividends in the form of a tax-deductible notional interest expense 
on  shareholders’  equity  in  accordance  with  Law  No.  9,249,  dated  December  26,  1995,  as  amended.    The  rate  at 
which  tax-deductible  interest  may  be  paid  is  limited  to  the  product  of  the  average  TJLP  and  shareholders’  equity 
during the relevant period and cannot exceed the greater of: 

• 

• 

50%  of  net  income  (before  taking  into  account  the  distribution  and  any  deductions  for  income 
taxes and after taking into account any deductions for social contributions on net profits) for the 
period in respect of which the payment is made; and 

50% of retained earnings. 

Distribution  of  interest  on  our  shareholders’  equity  is  a  tax-deductible  expense,  for  both  income  tax  and  social 
contribution purposes.  The amount paid to shareholders as interest on shareholders’ equity, net of any withholding 

75 

 
 
tax, may be included as part of any mandatory dividend.  We are required to pay a mandatory dividend of not less 
than 25% of our net income, subject to some exceptions and adjustments. 

For tax purposes, payments of interest on shareholders’ equity are recognized when the payments are declared, not 
when they are paid, within 60 days of the following general shareholders’ meeting.  In April, May and November 
2003 and January 2004, we declared interest on shareholders’ equity to be paid after our 2004 general shareholders’ 
meeting.  In February and December 2004 and January 2005, we declared interest on shareholders’ equity to be paid 
within  60  days  after  our  2005  general  shareholders’  meeting.    In  April,  June,  October  and  December  2005,  we 
declared interest on shareholders’ equity to be paid within 60 days after our 2006 general shareholders’ meeting.  On 
April 20 and December 14, 2006, we declared interest on shareholders’ equity in the amount of R$129.6 million and 
R$141.2 million, respectively.  The payments of interest on shareholders’ equity declared in 2006 began being made 
on June 29, 2007.  

Interest on shareholders’ equity is recorded as part of, but is immediately reversed under, the financial expenses line 
item in our statement of operations.  The tax deduction relating to distributions of interest on shareholders’ equity is 
reflected  under  the  income  tax  and  social  contribution  line  items  in  our  statement  of  operations.    This  tax  benefit 
consequently contributes positively to net income in our statement of operations.

ITEM 6. 

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES 

6.A. Directors and Senior Management 

Under  our  by-laws  and  Brazilian  Corporate  Law,  we  are  managed  by  our  board  of  directors  (Conselho  de 
Administração),  which  currently  consists  of  ten  directors,  and  a  board  of  executive  officers  (Diretoria),  which 
currently consists of six executive officers.   

As  our  controlling  shareholder,  the  State  has  the  ability  to  control  the  election  of  the  board  of  directors  and, 
therefore, our direction and future operations.  Upon the election of a new Governor and any resulting change in the 
administration  of  the  State,  all  or  some  of  the  members  of  the  board  of  directors,  including  the  chairman,  have 
historically been replaced by designees of the new administration.  The board of directors may in turn replace some 
or all of the executive officers. 

Board of Directors 

Our by-laws provide for a minimum of five and a maximum of 11 directors.  The members of our board of directors 
are  elected  at  a  general  shareholders’  meeting  to  serve  renewable  one-year  terms.    Each  member  of  our  board  of 
directors must be one of our shareholders, under Brazilian Corporate Law, and a resident of Brazil, under our by-
laws.  Pursuant to our by-laws, our employees have the option to elect one member of our board of directors, who 
must  be  an  employee  with  more  than  two  years  of  service  to  us.    Currently,  our  employees  have  not  elected  a 
director.  In addition, pursuant to Brazilian Corporate Law, at least one member of the board of directors of mixed 
capital  companies,  such  as  us,  must  be  appointed  by  the  minority  shareholders.    Finally,  according  to  the  Novo 
Mercado rules, at least 20% of the board of directors must be comprised of independent members. 

The current members of our board of directors were elected in the general shareholders’ meeting held on April 30, 
2007.    The  tenure  of  the  directors  will  end  upon  the  election  of  the  new  members  at  the  general  shareholders’ 
meeting  to  be  held  in  April  2008.    Currently,  we  have  three  directors  considered  independent  under  the  Novo 
Mercado rules. 

77 

 
 
 
 
 
Our board of directors ordinarily meets once a month or when called by a majority of the directors or the chairman.  
Its responsibilities include the establishment of policy and general orientation of our business and the appointment 
and supervision of our executive officers. 

The following are the names, ages, position and brief biographical descriptions of the current members of our board 
of directors:

6.B. Compensation 

Pursuant  to  Brazilian  Corporate  Law,  our  shareholders  are  responsible  for  establishing  the  aggregate  amount  of 
compensation  we  pay  to  the  members  of  our  board  of  directors,  members  of  our  fiscal  council  and  our 
executive officers. 

For the year ended December 31, 2006, the aggregate compensation, including benefits in kind granted, that we paid 
to members of our board of directors and to our executive officers for services in all capacities was approximately 
R$3.1 million.  In addition, in 2006, the executive officers accrued pension benefits of approximately R$0.5 million, 
and we have set aside R$0.5 million with respect to such pension benefits.  The members of our board of directors 
did not receive any such benefits. 

81 

 
 
 
Profit Sharing and Pension Plans 

We  have  established  a  defined-benefit  pension  and  benefits  fund  (Fundação  Sabesp  de  Seguridade  Social),  or 
SABESPREV, to provide our employees with retirement and pension benefits.  This pension plan provides defined-
benefit  payments  to  former  employees  and  their  families.    Both  we  and  our  employees  make  contributions  to  the 
pension  plan.    Our  contributions  include  the  responsibility  assumed  relating  to  service  prior  to  the  constitution  of 
SABESPREV, which is payable up to February 2011.  We made contributions to the pension plan totaling R$10.3 
million in 2004, R$11.3 million in 2005 and R$11.4 million in 2006.  See note 13 to our financial statements. Based 
on independent actuarial reports, as of December 31, 2006, our obligation under this plan was R$321.2 million.  See 
note 13 to our financial statements.  

Since 1996, we have annually negotiated with the unions the profit-sharing plan.  We did not pay any profit-sharing 
amounts to our employees due to State Decree No. 43,794, which prohibited any profit-sharing amounts to be paid 
in 1999 to employees of State-controlled companies, including us.  On April 14, 2000, the State issued Decree No. 
44,836  which  allows  for  the  payment  of  profit-sharing  amounts  on  an  exceptional  basis,  provided  that  specific 
authorizations  are obtained  by  us  from  the  Wages Policy  Commission (Comissão  de  Política  Salarial).   We  have 
obtained  this  authorization  every  year  since  2000  and,  therefore,  paid  profit-sharing  amounts  to  our  employees 
during this period.   

The goals evaluate the business performance in the economic-financial, operating and administrative aspects.  Over 
the  years,  the  programs  have  suffered  some  changes.    In  1996,  1997  and  1998,  the  payment  was  allocated  to  all 
active  employees  with  more  than  six  months  of  service  with  the  company.  As  from  2000,  the  payment  was  then 
allocated to all active employees with more than three months of service with the company.  Up to 2004, the general 
goals  were  established  to  evaluate  Sabesp  as  a  whole,  and  others  goals  were  established  to  evaluate  the  various 
business  units  and  25%  of  the  profit-sharing  payments  were  made  as  each  of  the  company’s  general  goals  were 
accomplished, while the other 75% were effected as each of the various business units fulfilled its goals.  As from 
2005,  all  of  the  goals  established  evaluate  Sabesp  as  a  whole  and  50%  of  the  payment  has  been  effected  as  the 
principal  financial  goal  is  fulfilled,  and  the  other  50%  of  the  payment  has  been  effected  as  each  one  of  the  other 
established goals is fulfilled.  The payments are reduced proportionately if the goals are not fully attained.  Up to 
2006, the payment was effected in a six-month basis.  The program for 2006 was paid on an annual basis. 

We recorded profit-sharing expenses of R$40.3 million in 2004, R$44.3 million in 2005 and R$79.5 million in 2006.  
We believe that the profit-sharing plan has, in the past, contributed to increased employee productivity.  We do not 
have a stock-option plan for our employees. 

6.C. Board Practices 

The members of our board of directors are elected at a general shareholders’ meeting to serve renewable one-year 
terms.  Our board of directors ordinarily  meets once a  month  or when called by a  majority of the directors or the 
chairman.  See “– Board of Directors.”   

Our  board  of  executive  officers  is  composed  of  six  executive  officers  appointed  by  our  board  of  directors  for 
renewable  two-year  terms.    Meetings  of  our  board  of  executive  officers  are  held  weekly  in  the  case  of  ordinary 
meetings  or  when  called  by  the  chief  executive  officer  in  the  case  of  special  or  extraordinary  meetings.    See  “– 
Board of Executive Officers.” 

None  of  our  directors  and  executive  officers  is  party  to  an  employment  contract  providing  for  benefits  upon 
termination of employment, except for those officers who are also our employees, in which case they are granted all 
benefits regularly applicable.   

Fiscal Council (Conselho Fiscal) 

Our Conselho Fiscal, which is established on a permanent basis and generally meets once a month, consists of five 
members  and  five  alternates.    The  current  members  of  our  Conselho  Fiscal  were  elected  in  the  shareholders’ 
meeting  held on April  30, 2007.   Their tenure will  end in 2008.   The primary  responsibility of the  fiscal council, 

82 

 
 
 
which  is  independent  from  management  and  from  the  external  auditors  appointed  by  our  board  of  directors,  is  to 
review our financial statements and report on them to our shareholders. 

The following are the current members and alternate members of our fiscal council:

Audit Committee 

Our  by-laws  provide  for  an  audit  committee  to  be  comprised  of  three  board  members,  who  shall  cumulatively 
comply with the requirements of (1) independence, (2) technical expertise, and (3) availability.  The members may 
be  appointed  simultaneously  as  their  appointment  to  the  board  of  directors,  or  by  later  resolution  of  the  board  of 
directors.   

The audit committee is responsible for assisting and advising the board of directors in its responsibilities to ensure 
the  quality,  transparency  and  integrity  of  the  Company’s  published  financial  information.    To  this  end,  the  audit 
committee  supervises  all  matters  relating  to  accounting,  internal  controls  and  the  internal  and  independent  audit 
functions.  The audit committee and its members have no decision making powers or executive functions. 

The minimum availability required from each member of the audit committee is thirty hours per month.  Since its 
implementation in July 2006, the audit committee has met three times a month on average.  Under our by-laws, the 
members  shall  exercise  their  roles  for  the  same  period  as  their  corresponding  term  of  office,  or  until  otherwise 
resolved by the general shareholders’ meeting or by resolution of the board of directors.   

At a board meeting held on May 10, 2007, the following members of the board of directors were elected to serve on 
our audit committee:

6D. Employees 

As of December 31, 2006, we had 16,978 full-time employees.  In 2006, we had an average of 350 trainees and 584 
apprentices (aprendizes), as defined by Federal Law No. 10,097 of December 19, 2000.   

The following table sets forth the number of our full-time employees by main category of activity and geographic

The  average  tenure  of  our  employees  is  approximately  16  years.  We  also  outsource  certain  services  such  as 
maintenance, delivery of water and sewage bills, meter reading, catering and security.  We believe that our relations 
with our employees are generally satisfactory. 

Approximately  70%  of  all  our  employees  are  members  of  unions.    The  four  main  unions  that  represent  our 
employees  are  the  Sindicato  dos  Trabalhadores  em  Água,  Esgoto  e  Meio  Ambiente  de  São  Paulo—SINTAEMA, 
Sindicato dos Trabalhadores da Região Urbana de Santos, São Vicente, Santos Metropolitan Region, Litoral Sul e 
Vale  Ribeira—SINTIUS,  the  Sindicato  dos  Engenheiros  do  Estado  de  São  Paulo—SEESP  and  the  Sindicato  dos 
Advogados  de  São  Paulo—SASP.  Our  most  recent  collective  bargaining  agreements,  which  became  effective  on 
May  1,  2007  and  will  expire  on  April  30,  2008,  do  not  contemplate  total  job  protection  for  our  employees.  
However, we have a formal understanding with the unions that represent our employees that we would not dismiss 
more than 2.0% of our current employees before April 30, 2008.  We have experienced the following strikes in the 
last  five  years,  none  of  which  interrupted  the  essential  services  that  we  provide:  a  two-day  strike  in  May  2003,  a 
two-day  strike  in  May  2004,  a  two-day  strike  in  June  2005  and  a  one-day  strike  in  May  2006.    We  have  not 
experienced any strike until March 31, 2007.  Under Brazilian law, our non-administrative employees are considered 
“essential employees” and therefore are limited in their right to strike.   

6.E. Share Ownership 

As of June 30, 2007, the members of the board of directors and the executive officers owned an aggregate of 4,808 
common shares.  The members of our board of directors and our executive officers, on an individual basis and as a 
group, beneficially own less than 1% of our common shares.  See “Item 7A. Major Shareholders and Related Party 
Transactions – Major Shareholder” for more information.  As of the same date, none of our directors and executive 
officers owned any stock option plans.   

ITEM 7.  MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS 

7.A. Major Shareholder 

Our  outstanding  share  capital  as  of  June  30,  2007  consisted  of    227,836,623  common  shares,  without  par  value. 
Under our by-laws and the laws of the State of São Paulo, the State is required to own at least one-half plus one of 
our outstanding common shares.  All of our shareholders, including the State, have the same voting rights.

7.B. Related Party Transactions 

Transactions with the State of São Paulo 

We have entered into extensive transactions with the State of São Paulo, which is our controlling shareholder, and 
we expect to continue to do so.  The State of São Paulo is our largest customer, it owns some of the facilities we use 
in our business, it is one of the governmental entities that regulate our business, and it has assisted us in obtaining 
financing on favorable terms. 

Many of our transactions with the State of São Paulo reflect policies of the State that depend on decisions of elected 
officials or public servants and are accordingly subject to change.  Among the practices that could change are those 
described below concerning the application of dividends to offset accounts receivable from the State, the provision 
of State guarantees, and the terms on which we use state-owned reservoir facilities. 

Provision of Services 

We  provide  water  and  sewage  services  to  the  Federal  Government,  the  State  and  municipal  governments  and 
government  entities  in  the  ordinary  course  of  our  business.    Sales  of  water  and  sewage  services  to  the  State, 
including  State  entities,  totaled  approximately  R$321.2  million  for  the  year  ended  December  31,  2006.    Our 
accounts receivable from  the State totaled  R$456.9  million as of December 31, 2006.  In addition, as required by 
law, we invest our cash and cash equivalents with government financial institutions in short-term securities. 

Payment of Pensions 

Pursuant to a law enacted by the State, certain former employees of some state-owned companies which merged to 
form Sabesp, who provided service to us between our inception and 1974, when the law was prospectively repealed, 
acquired a legal right to receive supplemental pension benefit payments which rights are referred to as “Plan G0.”  
These amounts are paid by us, on behalf of the State, and are claimed by us as reimbursements from the State, as 
primary obligor.  In 2006, we made payments to former employees of R$101.7 million in respect of Plan G0.  The 
State did not make any reimbursements in this period.  See note 6 to our financial statements.  The amount owed to 
us by the State for reimbursement of these costs was R$774.5 million as of December 31, 2006.  The State, however, 
has not agreed with this amount.  We have undertaken to conduct a joint inquiry with the State with respect to the 
methodology employed in determining the reimbursement amounts to ensure we reach a mutual agreement. 

Agreements with the State 

In  September  1997,  we  and  the  State  entered  into  a  memorandum  of  understanding  providing  that  we  would,  in 
effect,  apply  dividends  we  declared  that  were  otherwise  payable  to  the  State  to  offset  accounts  receivable  in 
connection with the provision of water and sewage services to the State and its controlled entities.  In 1998, 2000 
and  2001,  we  applied  dividends,  in  the  form  of  interest  on  shareholders’  equity  due  to  the  State  in  respect  of  its 
shareholding  in  us  to  settle  a  portion  of  the  unpaid  accounts  receivable  from  the  State.    In  1999,  we  did  not  pay 
dividends or other distributions to our shareholders. 

On December 11, 2001, we entered into an agreement with the State and the State Department of Water and Energy.  
Pursuant to this agreement, the State acknowledged and agreed, subject to an audit by a State-appointed auditor, to 
pay us amounts it owed to us in respect of: 

• 

• 

water  and  sewage  services  we  provided  to  governmental  agencies,  State-owned  autonomous 
entities and foundations through December 1, 2001; and 

supplemental  retirement  and  pension  benefits  we  paid  from  March  1986  to  November  2001  on 
behalf  of  the  State  to  former  employees  of  the  State-owned  companies  which  merged  to  form 

85 

 
 
 
Sabesp; as we did not reach an agreement regarding these amounts, a joint inquiry has commenced 
in order to ensure agreement between us and the State. 

As a result, a portion of these amounts became a long-term receivable from the State in our financial statements on 
December 31, 2001. 

The  agreement  provided  that  the  State  Department  of  Water  and  Energy  would  transfer  to  us  ownership  of  the 
Taiaçupeba, Jundiaí, Biritiba, Paraitinga and Ponte Nova reservoirs, which make up the Alto Tietê system, and that 
the fair value of these assets would reduce the amounts owed to us by the State. 

Under the December 2001 agreement, in July and August 2002, a State-owned construction company (Companhia 
Paulista de Obras e Serviços), or CPOS, on behalf of the State, and an independent appraisal firm (Engenharia de 
Avaliações),  or  ENGEVAL,  on  our  behalf,  presented  their  valuation  reports  relating  to  the  reservoirs.    Under  the 
agreement,  the  arithmetic  average  of  these  appraisals  is  deemed  the  fair  value  of  the  reservoirs.    The  appraisals 
contained in these reports were in the amounts of R$335.8 million and R$341.2 million, respectively.  Because we 
had already made investments in these reservoirs by then, the arithmetic average of the appraisals submitted to our 
board of  directors by  August 2002, R$300.9  million, was net of  a percentage  corresponding  to  these  investments.  
Our board of directors approved the valuation reports. 

Under the December 2001 agreement, for amounts due in excess of the fair value of the reservoirs, the State is to 
make payments in 114 consecutive  monthly installments, with the first payment to be made upon the latest of (1) 
210  days  after  the  date  of  the  agreement,  (2)  agreement  by  the  parties  on  the  fair  value  of  the  reservoirs  and  (3) 
conclusion  of  the  audit  by  a  State-appointed  auditor  of  amounts  owed.    The  nominal  amount  owed  by  the  State 
would not be indexed to inflation or earn interest if there was a delay in concluding the appraisal of fair value.  The 
installments will be indexed on a monthly basis by the IGP-M index, plus 6.0% per year, starting on the date the first 
installment becomes due. 

On October 29, 2003, the Public Prosecution Office of the State of São Paulo (Ministério Público do Estado de São 
Paulo), on behalf of the people of the State, brought a civil public action in a Trial Court of the State of São Paulo 
(12a Vara da Fazenda Pública do Estado de São Paulo) alleging that a transfer to us of ownership of the Alto Tietê 
system  reservoirs  from  the  State  Department  of  Water  and  Energy  would  be  illegal.    An  injunction  against  the 
transfer of ownership of such reservoirs was granted but was later reversed.  However, in October 2004, the court 
ruled in favor of the Public Prosecution Office of the State of São Paulo, which ruling we believe relates only to the 
illegality of the transfer of the reservoirs.  In response, we filed an appeal which is pending final decision and the 
State successfully filed an action suspending the lower court’s decision until final judgment is reached by the Court 
of Justice of the State of São Paulo.  We are unable to predict whether we will succeed in appealing such decision.  
However, we currently do not expect that an eventual unfavorable decision would have a material adverse effect on 
our business and financial condition.   

The December 2001 agreement also provided that the legal advisors of the State would carry out specific analyses, 
which have commenced, to ensure agreement among the parties as to the methodology employed in determining the 
amount  of  reimbursement  for  pension  benefits  owed  to  us  by  the  State.    Our  management  does  not  expect  these 
analyses to differ significantly from the amounts we have recorded in respect of these amounts.  The commencement 
of payments with respect to pension amounts owed to us by the State has been postponed until these analyses are 
completed,  the  appraisal  report  is  approved  and  the  credit  assignments  relating  to  the  transfer  of  the  reservoirs 
described above are formalized.  In addition, the transfer of these reservoirs is currently being disputed and we are 
not  certain  whether such transfer  will be legally allowed.   Under the December  2001  agreement, the  original  first 
payment was to be made in July 2002.  Based on Official Notice No. 53/2005 of the State Capital Defense Council 
(CODEC), dated March 21, 2005, negotiations are still ongoing between us and the State with a view to restatement 
of  the  debt  for  supplemental  retirement  and  pension  benefits,  under  the  terms  defined  in  the  December  2001 
agreement, including amounts due after November 2001.  These negotiations are expected to be consolidated in a 
second  amendment  to  the  December  2001  agreement.    We  hired  FIPECAFI  to  validate  the  actual  values  to  be 
reimbursed  by  the  State,  provided  by  the  Office  of  the  State  Attorney  General.    See  note  6  to  our  financial 
statements.

At  a  meeting  held  on  January  30,  2002,  our  board  of  directors  unanimously  declared  dividends,  in  the  form  of 
interest on shareholders’ equity, in an aggregate amount of R$489.8 million.  This distribution was paid on June 25, 
2002,  to  shareholders  of  record  as  of  February  7,  2002.    Accordingly,  the  State  was  entitled  to  receive  R$432.7 
million of this distribution and we paid the State R$347.3 million of this amount.  The State applied approximately 
R$202.3 million of the dividend it received to settle current accounts receivable owed by the State or its controlled 
entities.    We  have  withheld  the  remaining  share  of  the  dividend  that  the  State  was  entitled  to  pending  the  State’s 
payment of certain accounts receivable owed to us. 

At a  meeting, our board of directors reviewed our 2002 budget, which incorporated the payment to the State, and 
one  of our  directors voted against  us  making  this  payment.  We  cannot  assure you that  our  minority  shareholders 
will  not  contest  the  payment  of  a  cash  distribution  to  the  State  on  the  grounds  that  it  is  inconsistent  with  the 
September 1997 protocol of understanding. 

On April 29, 2002, our board of directors declared dividends, in the form of interest on shareholders’ equity, in an 
aggregate amount of R$108.2 million, paid in June 2003 to shareholders of record as of June 17, 2002.  The State 
applied the entire amount of this dividend, or R$77.4 million, to accounts receivable owed to us. 

On April 24, May 29, and November 20, 2003, and on January 8, 2004, our board of directors approved the payment 
of  dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  aggregate  amounts  of  R$40.2  million,  R$118.2 
million, R$154.9 million and R$190.8 million, respectively.  These dividends were paid on June 29, 2004. 

On February 26, 2004, December 16, 2004 and January 13, 2005, our board of directors approved the payment of 
dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  the  amount  of  R$39.3  million,  R$85.4  million  and 
R$28.2 million, respectively.  These dividends were paid on June 28, 2005. 

On  April  28,  2005,  our  board  of  directors  approved  the  payment  of  dividends,  in  the  form  of  interest  on 
shareholders’  equity,  in  the  amount  of  R$38.2  million,  to  be  paid  within  60  days  after  our  2006  general 
shareholders’ meeting.  On June 23, 2005, our board of directors approved the payment of dividends, in the form of 
interest  on  shareholders’  equity,  in  the  amount  of  R$66.8  million,  to  be  paid  within  60  days  after  our  2006 
shareholders’  meeting  to  shareholders  of  record  as  of  July  6,  2005.    On  October  20,  2005,  our  board  of  directors 
approved the payment of dividends, in the form of interest on shareholders’ equity, in the amount of R$85.2 million, 
to be paid within 60 days after our 2006 shareholders’ meeting to shareholders of record as of November 3, 2005.  
On  December  15,  2005,  our  board  of  directors  approved  the  payment  of  dividends  in  the  form  of  interest  on 
shareholders’ equity in the amount of R$158.1 million, to be paid within 60 days of our 2006 shareholders’ meeting 
to shareholders of record as of December 28, 2005.  On April 20, and December 14, 2006, our board of directors 
approved  the  payment  of  dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  the  amount  of  R$129.6 
million,  and  R$141.2  million,  respectively,  to  be  paid  within  60  days  after  our  2007  shareholders’  meeting  to 
shareholders of record as of May 3, 2006.  The amount related to the dividends approved in 2006 for the controlling 
shareholder, the State of São Paulo, was R$136.1 million.  The payments of interest on shareholders’ equity declared 
in  2005  began  being  made  on  June  27,  2006.    The  payments  of  interest  on  shareholders’  equity  declared  in  2006 
began being made on June 29, 2007. 

On March 22, 2004, we and the State executed the first amendment to the December 2001 agreement.  Under this 
amendment,  the  State  acknowledged  a  debt  owed  to  us  of  R$581.8  million,  related  to  unpaid  accounts  receivable 
from the State until February 29, 2004, and we acknowledged the aggregate amount of R$518.7 million due to the 
State as dividends in the form of interest on shareholders’ equity.  See note 6 to our financial statements.  

Accordingly, we and the State agreed to set-off each other’s credit up to the limit of R$404.9 million (value adjusted 
up  to  February  2004).    The  remaining  amount  of  R$176.9  million  as  of  February  29,  2004  of  the  State’s 
consolidated  debt  will  be  paid  in  monthly  consecutive  installments  from  May  2005  until  April  2009.    These 
installments will be indexed according to the IPCA index, plus an interest rate of 0.5% per month. 

With the execution of the March 2004 agreement, we were able to reconcile the compensation of part of the values 
owed to us by the State for the use of water and sewage services until February 2004 with values owed to the State 
by us as interest on shareholders’ equity.  The remaining amount of interest on shareholders’ equity owed by us to 
the State, of R$113.8 million was netted against accounts overdue after February 2004. 

87 

 
 
This amendment did not alter the payment terms and conditions related to the supplemental retirement and pension 
benefits we pay on behalf of the State, which remain governed by the terms of the December 2001 agreement itself. 

As  of  December  31,  2006,  the  amounts  owed  to  us  by  the  State  for  the  provision  of  water  and  sewage  services 
included R$148.8 million, which was considered overdue as of February 29, 2004.  As of December 31, 2006 the 
State  owed  us  an  additional  R$308.0  million  in  accounts  receivable  related  to  the  provision  of  water  and  sewage 
services rendered from February 2004.  With respect to reimbursement for pensions paid on behalf of the State, the 
State owed us R$774.5 million as of December 31, 2006 (R$320.6 million of which was acknowledged by the State 
in the December 2001 agreement subject to a further audit).  We expect amounts owed to us by the State for water 
and sewage services and reimbursements for pensions paid to increase in the future.  We have not established any 
provisions for any amounts due to us by the State, because we expect to recover these amounts and net losses are not 
considered probable.   

During 2005, we received payment installments from the State in the amount of R$35.8 million, for the months from 
May to December 2005 and we offset the remaining balance of interest on shareholders’ equity owed by us to the 
State  in  the  amount  of  R$105.5  million  against  the  balance  due  to  us  for  water  and  sewage  services  provided  as 
contemplated in the first amendment to the December 2001 agreement.  

In 2006, we received payment installments from the State in the amount of R$199.4 million.  As of December 31, 
2006, our dividends payable to the State, due from 2004 through 2006, were in the amount of R$396.4 million.  We 
are currently unable to determine the amount, if any, of the portion of these declared dividends that the State will 
apply to the current and future accounts receivable owed to us by the State or its controlled entities.  

Investment of Liquid Assets 

Our cash and cash equivalents invested with State financial institutions in short-term securities amounted to R$288.0 
million as of December 31, 2006. 

Government Guarantees of Financing 

In  some  situations,  the  Federal  Government,  the  State  or  government  agencies  guarantee  our  performance  under 
debt- and project-related agreements. 

On December 17, 1992, the State entered into a loan agreement with the World Bank in the amount of US$119.0 
million.    This  loan  was  guaranteed  by  the  Federal  Government  and  its  proceeds  were  designated  to  finance  the 
environmental clean-up of the Guarapiranga basin.  Pursuant to this agreement, we would receive a loan from the 
State  to  be  used  in  the  expansion  of  the  wastewater  collection  network  and  sewage  treatment  facilities  in  the 
Guarapiranga reservoir.  As a result, on March 12, 1993, we entered into an agreement with the State pursuant to 
which the State transferred to us US$37.0 million of this loan, which loan amount was increased to US$42.5 million 
pursuant to an amendment entered into between the State and us in September of 1999.  We have pledged three of 
our  properties  as  collateral  for  this  financing  in  the  amount  of  R$60.5  million,  according  to  a  valuation  of  the 
properties carried out in November 2005.  As of December 31, 2006 our outstanding debt relating to this loan was 
approximately US$2.2 million. 

The  State  has  also  guaranteed  a  portion  of  our  repayment  obligations  under  loan  agreements  that  we  entered  into 
with  the  Federal  Government  in  1994  through  its  financial  agent,  Banco  do  Brasil  S.A.  which  totaled  R$2,069.8 
million as of December 31, 2006.  The Federal Government has guaranteed, and the State has provided a counter-
guarantee, in respect of the financial agreement we entered into with the Inter-American Development Bank in 2000 
for  the  total  aggregate  amount  of  US$200  million  related  to  the  financing  of  the  Tietê  River  recovery  project  to 
reduce pollution. 

On  August  6,  2004,  we  entered  into  a  credit  agreement  with  the  JBIC  for  the  financing  of  the  Environmental 
Recovery  Program  for  the  Santos  Metropolitan  Region,  which  was  guaranteed  by  the  Federal  Government,  with 
counter-guarantee from the State of São Paulo, for an aggregate principal amount of R$382.8 million.  In addition to 
the amount received under the JBIC credit agreement, we intend to invest up to R$355.1  million in this program.  

88 

 
 
We  are  currently  also  negotiating  with  BNDES  and  Caixa  Econômica  Federal  for  additional  loans  to  finance 
portions of our capital expenditure program. 

Use of State-Owned Reservoir Facilities 

We currently use the Guarapiranga and Billings reservoirs and a portion of some of the reservoirs of the Alto Tietê 
system, which are owned by another company controlled by the State.  We do not pay any fees with respect to the 
use of these reservoirs.  We are, however, responsible for maintaining them and funding their operating costs.  The 
State incurs no operating costs on our behalf.  If these facilities were not available for our use, we would have to 
obtain water from more distant sources, which would be more costly. 

The  arrangement  not  to  pay  any  fees  to  the  State  for  the  use  of  certain  reservoirs  of  the  Alto  Tietê  system  is 
addressed by a number of formal agreements first entered into on March 31, 1992 and on April 24, 1997 and later 
amended on March 16, 2000 and on November 21, 2001.  As part of these arrangements, we agreed to fund 100.0% 
of  the  estimated  costs  of  the  1992  agreement  equal  to  R$27.8  million  and  75.0%  of  the  1997  agreement  equal  to 
R$63.4  million  which  was  already  disbursed,  and  the  Government  of  the  State,  through  the  State  Department  of 
Water and Energy, agreed to fund approximately 25% of the estimated costs of the 1997 agreement equal to R$21.1 
million, to construct ducts, tunnels and other facilities to interconnect the Tietê River with the Biritiba and Jundiaí 
reservoirs  and  with  other  bodies  of  water  in  exchange  for  our  use  of  the  reservoirs  over  a  30-year  period.    The 
amendments to the 1997 agreement increased our obligations under this agreement by R$5.9 million. 

We have the right to draw water from and release emissions into the reservoirs in the Alto Tietê system over a 30-
year period which began in 1997. 

Our use of the Billings and Guarapiranga reservoirs is provided for through a grant issued by the State Department 
of Water and Energy.  We have the right to use these reservoirs as long as we remain responsible for maintaining 
them and funding their operating costs. 

Water Use Incentive Agreements 

We  have  entered  into  agreements  with  public  entities,  including  State  entities  and  municipalities,  that  manage 
approximately 6,000 properties under which we provide these entities with a 25.0% tariff reduction for the water and 
sewage services we provide if such entities implement our program for the rational use of water, which includes a 
reduction  of  at  least  10.0%  in  water  consumption.    These  agreements  are  valid  for  a  period  of  12  months  with 
automatic renewal for equal periods.  Pursuant to the terms  of these agreements, if these entities fail to  make any 
payment  on  a  timely  basis  to  us,  we  have  the  right  to  cancel  the  agreement,  thereby  revoking  the  25.0%  tariff 
reduction. 

Transactions with SABESPREV Pension Fund 

SABESPREV  is  the  funded  defined-benefit  pension  plan  that  we  established  to  provide  our  employees  with 
retirement and pension benefits.  The assets of SABESPREV are independently held, but we nominate the majority 
of directors of SABESPREV.  Both we and our employees make contributions to the pension plan.  We contributed 
R$10.3 million, R$11.3 million and R$11.4 million in 2004, 2005 and 2006.  

On  May  29,  2001,  a  Federal  law  was  enacted  which,  among  other  things,  limits  the  amount  mixed  capital 
companies, like us, may contribute to their pension plans.  Specifically, the ordinary contributions made by us to our 
pension  plans  may  not  exceed  the  contributions  made  by  the  beneficiaries  of  these  plans.    Studies  have  been 
undertaken in order to cure the deficit with respect to the current plan and transform it into a defined contribution 
plan.

Legal Proceedings 

In  the  ordinary  course  of  our  business,  we  are  a  party  to  judicial  and  administrative  proceedings  relating  to  civil, 
environmental, labor and tax matters.  As of December 31, 2006, we estimated that these legal proceedings totaled 
approximately R$2,128.0 million (excluding the amount of R$19.5 milllion related to court deposits).  This amount 
was based on probable and possible losses and on the value attributed to the lawsuit by the plaintiffs in some cases 
and  on  the  economic  value  of  the  lawsuits  in  others.    Out  of  this  total  amount  of  contingencies,  approximately 
R$1,062.6  million  relate  to  tariff-related  legal  proceedings  and  consumers  claims,  approximately  R$367.0  million 
relate  to  contractors  claims,  approximately  R$126.1  million  relate  to  tax  proceedings,  approximately  R$114.9 
million  relate  to  labor  proceedings,  approximately  R$258.4  million  relate  to  civil  public  actions  related  to 
environmental matters and R$218.5 million relate to other civil matters.  On the same date, the provisions for legal 
contingencies totaled R$657.6 million (excluding the amount of R$19.5 million related to court deposits), of which 
approximately  R$273.3  million  relate  to  tariff-related  legal  proceedings  and  consumers  claims,  approximately 
R$168.5 million relate to contractors claims, approximately R$21.2 million relate to tax proceedings, approximately 
R$71.2  million  relate  to  labor  proceedings,  approximately  R$66.0  million  relate  to  civil  public  actions  related  to 
environmental matters and approximately R$76.9 million relate to other civil matters.  

The  difference  between  the  provisioned  amount  and  the  total  amount  of  the  contingencies  derives  from  the 
methodology for establishing our provisions.  This methodology takes into account:  (1) the probability of loss of 
each lawsuit, based on the alleged facts, the claim based on the factual circumstances vis-à-vis the law, as well as 
prevailing precedents in similar cases; and (2) the calculation of the provisioned amounts, which requires significant 
judgment and  in  certain  circumstances, given the nature of  the claim,  we  are unable  to estimate  with  accuracy  its 
exposure. In these cases, we have taken into account the  value attributed to the lawsuits by the plaintiff and legal 
opinions  of  counsel  in  charge  of  each  lawsuit.    Once  the  methodology  is  applied,  as  a  general  rule,  we  make  the 
provisions only for the lawsuits that are considered as probable loss.  

We cannot give any assurances either as to the sufficiency of the provisioned amount to cover the contingencies or 
as to the total amount of potential liabilities that we may incur or penalties that may be imposed.  We may not obtain 
a  favorable  outcome  in  the  administrative  or  court  proceedings  to  which  we  are  a  party.    In  addition,  the  total 
amount of the contingencies, based on the value attributed to the lawsuit by the plaintiff, may not correspond to the 
economic  value of  the  lawsuits,  which  may be  substantially  higher than  the  total amount  of contingencies.   If the 
economic  outcome  of  these  lawsuits  is  higher  than  the  amount  attributed  to  the  lawsuit  by  the  plaintiff  or,  in  the 
event the total amount of our provisions does not suffice to pay the contingencies due, we could incur greater costs 
than  those  that  were  originally  foreseen.    If  these  costs  are  significant,  our  results  of  operations  and  financial 
condition could be negatively affected. 

Civil Public Actions Related to Environmental Matters 

We are a party to civil public actions brought by municipalities that seek cessation of the collection of fees relating 
to  sewage  services,  alleging  that  we  do  not  treat  the  sewage  in  these  municipalities  and  that  we  failed  to  make 
certain investments in sewage treatment facilities as provided in the relevant concession contracts.   

In  addition,  we  are  being  sued  by  the  Public  Prosecution  Office  of  the  State  of  São  Paulo  (Ministério  Público  do 
Estado  de  São  Paulo)  as  well  as  some  non-governmental  organizations  through  a  number  of  environmental  civil 
public actions: (1) aiming to enjoin us from releasing raw sewage into certain local water courses; (2) in some cases 
seeking remedies for environmental damages, which have not yet been specified and evaluated by technical experts 
of the courts; and (3) aiming to require us to install and operate sewage treatment  facilities in those locations.  In 
each  case,  we  are  subject  to  daily  fines  for  noncompliance  therewith.    In  our  response  to  these  lawsuits  we 
emphasize  that  the  installation  and  operation  of  sewage  treatment  facilities  in  those  locations  is  included  in  our 

90 

 
 
business  plan  and  that  the  immediate  cessation  of  the  release  of  raw  sewage  into  the  relevant  local  water  courses 
would  hinder  us  from  collecting  sewage  –  a  primary  necessity  –  in  those  locations,  causing  even  more  damages 
against the environment and public health.  In most of these lawsuits, no final judicial decision has yet been reached 
by  local  judges.    Although  we  are  not  able  to  predict  the  final  outcome  of  these  lawsuits,  we  believe  that  the 
outcome, if unfavorable to us, may have a material adverse effect on us. 

The civil public lawsuits to which we are party include the following: 

(1)  The  Public  Prosecution  Office  of  the  State  of  São  Paulo  has  brought  a  civil  public  action  before  the  São 
Bernardo  do  Campo  Court  (5a.  Vara  Cível  de  São  Bernardo  do  Campo)  seeking  reparation  for  environmental 
damage  caused  by  us  dumping  sludge  from  our  water  treatment  facilities  into  certain  receiving  waters,  the 
immediate  cessation  of  this  practice  and  the  implementation  of  an  environmental  recovery  project.    The  Court  of 
Justice of the State of São Paulo (Tribunal de Justiça do Estado de São Paulo) ruled against us and ordered that we 
stop  dumping  sludge  within  a  year  from  the  date  the  decision  is  considered  final,  or  to  pay  a  daily  penalty  of 
R$10,000, in addition to repair the environmental damage.  This decision is not yet final.  We are currently unable to 
evaluate the extent or cost of any remedy that we may be held responsible for in connection with this matter.  We 
have  not  made  any  provisions  for  this  proceeding.  Our  internal  legal  counsel  considered  the  risk  of  loss  in  this 
lawsuit as probable and we have provisioned the amount of R$141,000 based on the value attributed to the lawsuit 
by the plaintiff. 

(2)  The  Public  Prosecution  Office  of  the  State  of  São  Paulo  brought  a  civil  public  action  against  us  before  the 
Paraguaçu  Paulista  Court  of  Law  (1a.  Vara  de  Paraguaçu  Paulista),  which  seeks  reparation  for  and  cessation  of 
environmental  damage  allegedly  caused  by  the  release  of  raw  sewage  into  the  Alegre  River,  situated  in  the 
municipality of Paraguaçu Paulista.  The court ruled against the Company in the first instance, requiring that we (a) 
cease  the  release  of  raw  sewage  into  the  Alegre  River;  (b)  invest  in  a  water  and  sewage  treatment  facility  in  the 
municipality  of  Paraguaçu  Paulista;  and  (c)  pay  an  administrative  penalty  in  the  amount  of  R$116.9  million  for 
environmental damages (the adjusted amount, as of December 31, 2006, was approximately R$168.9 million).  The 
decision imposes an additional daily penalty on us if we fail to comply with (a) and (b) above.  We have appealed 
this decision. 

On September 21, 2006, the Court of Justice of the State of São Paulo ruled against our appeal.  While we maintain 
our  legal  right  to  appeal  the  decision  issued  by  the  Court  of  Justice  of  the  State  of  São  Paulo,  we  are  currently 
negotiating with the Public Prosecution Office of the State of São Paulo with respect to the terms and conditions of a 
possible settlement agreement, which, if entered into, will result in the effective settlement and termination of this 
legal proceeding.  While the exact amounts payable under any such settlement have not yet been quantified and the 
terms of any such settlement remain subject to further negotiation, our management believes that the total estimated 
disbursements  will be  considerably less than  the aggregate amount  of the administrative penalties required by the 
court’s  decision  as  described  above.    The  first  negotiations  of  the  settlement  agreement  resulted  in  an  estimated 
disbursement  of  R$20.7  million.    In  the  last  quarter  of  2006,  the  scope  of  the  agreement  was  expanded  and  new 
projects were included in the settlement, totaling R$33.6 million, which has been recorded as a provision. 

In the event that we are unable to settle with the Public Prosecution Office of the State of São Paulo under the terms 
currently contemplated, our results of operations may be materially adversely affected. 

(3) Civil public action against us and the municipality of Cotia aiming at the joint and several liabiliaty of Sabesp 
and  this  municipality  with  respect  to:  (a)  the  obligation  to  interrupt  the  disposal  of  sewage  into  the  Cotia  River, 
subject to a daily fine in case of noncompliance; (b) the obligation to submit to previous treatment the sewage before 
dumping  it  into  the  Cotia  River,  subject  to  a  daily  penalty  in  case  of  noncompliance,  and  (c)  the  payment  of 
indemnity for environmental damages caused to the soil, water sources and underground and superficial bodies of 
water that cannot be recovered. The court decided in favor of (a) and (c) above.  The technical expert of the court 
calculated  the  indemnity  in  the  amount  of  R$5.8  million  for  environmental  damages.    This  amount  is  still  under 
discussion  and  depends  on  final  decision  of  the  court.    Our  internal  legal  counsel  evaluated  the  risk  of  loss  as 
probable.  As of December 31, 2006, we recorded a provision in the amount of R$ 5.8 million.   

91 

 
 
 
(4) On February 25, 2003, a request for a preliminary injunction was filed against us, aiming at restricting us from 
disposing  sewage  without  due  treatment,  in  the  municipality  of  Lutécia.    The  injunction  was  granted  in  order  to 
determine that payments for water and sewage services by users be deposited with the court until we have made the 
necessary  investment  in  the  water  and  sewage treatment  facility of the  municipality, in addition  to  paying a  daily 
fine in the amount equivalent to 1,000 minimum salaries (approximately R$350,000) in the event we do not cease to 
discharge raw sewage.  The injunction was suspended at our request until a final ruling is issued.  After submission 
of an expert report, the Public Prosecution Office of the State of São Paulo requested that we be sentenced to pay an 
amount of R$82.8 million (the adjusted amount, as of December 31, 2006, was approximately R$119.6 million) in 
addition  to  the  daily  fines.    We  and  the  Public  Prosecution  Office  of  the  State  of  São  Paulo  are  engaged  in 
negotiations in order to settle this legal proceeding.  We have not made any provisions for this proceeding as the risk 
of loss was evaluated as possible. 

(5) On February 17, 2003, a civil public action was brought against us before the Paraguaçu Paulista Court of Law 
with  respect  to  the  municipality  of  Borá,  related  to  the  obligation  not  to  dump  and  discharge,  under  any 
circumstance, raw sewage in the Borá stream, or in any other municipality, as well as the obligation to invest in the 
water and sewage treatment facility and immediately carry out the necessary construction works for the treatment of 
sewage. A preliminary injunction was not granted by the court of law.  The technical expert of the court calculated 
the amount of R$48.1 million as indemnity for environmental damages.  Our expert contested this amount and no 
judicial decision has been issued yet.  Sabesp carried out the construction works that CETESB requested to adapt the 
sewage treatment to the legislation currently in force.  CETESB issued a temporary operating license on August 25, 
2006, with validity until August 25, 2011.  Our internal legal counsel evaluated the risk of loss as possible. 

(6)  A  civil  public  action  was  brought  against  us  by  the  Coordination  Council  for  the  Civil  Entities  of  Piracicaba 
(Conselho  Coordenador  das  Entidades  Civis  de  Piracicaba)  concerning  the  limits  for  water  collection  from  the 
Piracicaba River and the operation of the Cantareira water distribution system.  The plaintiff requests, among other 
things, a prohibitory injunction in order to restrict the amount of water we collect, the reduction of the Piracicaba 
River’s collection limit and the payment of damages to the riparian cities in order to cover the direct and indirect 
environmental damages caused by the installation and operation of the Cantareira water distribution system.  After 
our  defense,  the  injunction  was  not  granted,  and  this  action  is  now  awaiting  judgment  by  the  lower  court.    This 
proceeding is still at an initial stage and no amount has been determined so far for the alleged damage.  Our internal 
legal counsel evaluated the risk of loss as remote so that we have not made any provisions for this proceeding. 

We are also involved in other environmental lawsuits in municipalities where we operate, arising from the discharge 
of raw sewage, which are considered as possible and probable losses by our legal counsel.  We provisioned amounts 
that  not  always  represent  the  final  amount  to  be  disbursed  as  indemnity  for  the  alleged  damages  because  of  the 
current  phase  of  the  lawsuits  and  the  impossibility  for  our  management  to  estimate  on  a  reasonable  basis  future 
amounts  to  be  disbursed.    As  of  December  31,  2006,  the  total  amount  provisioned  was  R$65,988,  including  the 
provisions described in itens (1), (2) and (3) above. 

Labor Proceedings 

We are a party to numerous lawsuits and administrative proceedings involving SINTAEMA and current and former 
employees. 

On January 9, 1990, SINTAEMA initiated a lawsuit against us, alleging that we had failed to pay certain employee 
benefits and were required to make a penalty payment to SINTAEMA under a then existing collective bargaining 
agreement.  On July 31, 1992, the labor court issued a ruling against us, but did not award damages to SINTAEMA 
at that time.  We and SINTAEMA are currently engaged in negotiations concerning the amount to be paid by us.  
We also filed a writ of mandamus seeking a court decision establishing that the penalty imposed against us, totaling 
approximately R$6.7 million, as of December 31, 2006, is excessive since it exceeds the principal amount by a large 
margin.  Our request was denied by the courts and the lawsuit is now awaiting a final decision at the Superior Labor 
Court (Tribunal Superior do Trabalho).  We currently cannot predict the amount that we will be required to pay to 
SINTAEMA and we have not made any provisions for this proceeding.   

On  October  6,  1989,  SINTAEMA  filed  a  lawsuit  against  us,  asking  for  the  payment  of  salary  differences  arising 
from  additional  payments  due  to  unhealthy  work  conditions  from  September  1987  through  February  1991.    On 

92 

 
 
December  19,  1997,  the  Superior  Labor  Court  issued  a  decision  unfavorable  to  us.    We  appealed  against  this 
decision,  however,  it  was  maintained  by  the  Superior  Labor  Court.    SINTAEMA  started  the  enforcement  of  the 
judicial decision and the valuation report of the technical expert of the court was presented on February 21, 2007 in 
the updated amount of R$28.3  million.  Our internal legal counsel considered the risk of loss as probable and the 
amount was provisioned on December 31, 2006. 

We are defendants in 1,941 labor proceedings and in one civil public action initiated by and on behalf of some of 
our current and former employees relating to certain benefits awarded by Law No. 4,819, dated August 26, 1958.  In 
all cases, we claim that the State, and not us, is responsible for the payments due to the plaintiffs.  As of the date of 
this annual report, we and the State have not agreed on the amounts to be reimbursed.  The civil public action is now 
awaiting decision on the merits.  Some labor and civil proceedings have been ruled upon by the lower courts, but no 
final decision has been issued in any of the legal proceedings as of the date of this annual report.  An injunction was 
granted by a lower court in the civil public action to compel us to pay the benefits awarded by Law No. 4,819 to all 
plaintiffs in that lawsuit.   

As of December 31, 2006, the total amounts involved related to labor proceedings were R$114.9  million for risks 
considered as probable and possible losses.  We had established a provision totaling R$71.2 million with respect to 
potential damages in lawsuits and administrative proceedings involving present and former employees, including the 
lawsuits  described  in  the  preceding  paragraphs,  based  on  calculations  made  by  our  legal  and  human  resources 
departments. 

Tax Proceedings 

We filed a claim in July 1999 to challenge the creation by the municipality of the City of São Paulo of a tax on the 
use of public areas.  The tax would apply to our water and sewage mains and other installations located in public 
areas.  Based on the advice of our internal legal counsel, we believe that this municipal tax is unlawful because it 
was established by a municipal decree instead of a municipal statute.  We are currently disputing the creation of this 
tax  and  any  related  tax  assessment.    On  May  11,  2000,  the  trial  court  of  the  State  of  São  Paulo  (12a.  Vara  da 
Fazenda Pública do Estado de São Paulo) issued a decision upholding this  municipal tax.  We have appealed the 
trial court decision to the Court of Justice of the State of São Paulo.  A recently approved law enacted the tax on the 
use  of  public  areas  in  the  City  of  São  Paulo.    In  April  2004,  we  filed  a  request  for  an  injunction  seeking  the 
suspension  of  the  tax  assessment  by  the  municipality.    The  injunction  was  granted  by  the  lower  court  and  later 
maintained in the decision issued by the lower courts.  The municipality has appealed this decision to the Court of 
Justice  of  the  State  of  São  Paulo  and  the  decision  is  still  pending.    We  currently  cannot  estimate  the  potential 
increase in our expenses if we were required to pay this tax or if any future assessment of this tax is retroactive to 
1999.  To date, we have not established a provision for any potential expense arising from this municipal tax.   

We also took legal action to challenge a City of São Paulo municipal law enacted in December 2002 that revoked 
our blanket exemption from municipal taxes.  As a result of the loss of our exemption from municipal taxes, we may 
be subject to a tax on services charged at a rate of 5.0% on our gross revenue from sewage services.  Our request for 
an  injunction  against  the  municipality  was  granted  by  the  Court  of  Justice  of  the  State  of  São  Paulo,  and  this 
injunction was maintained after the filing of an appeal by the municipality.  However, on May 5, 2005, the lower tax 
court  issued  a  decision  against  us  and  revoked  the  injunction  granted  in  our  favor.    We  appealed  the  decision  to 
maintain  the  effects  of  the  injunction  until  a  trial  decision  in  this  legal  proceeding  is  issued,  but  our  appeal  was 
denied.  To date, despite our efforts to obtain a decision from the Superior Court of Justice to maintain the effects of 
the  injunction  until  a  final  judgment, we have  not  been able  to  revert the lower  tax  court  decision.    We intend to 
challenge the loss of the exemptions  to  the fullest extent  permitted by law.  This  legal action, for which  potential 
expenses  amount  to  approximately  R$70.0  million,  was  assessed  by  our  tax  advisors  as  being  a  possible  loss; 
accordingly, no provision has been recorded.   

In November 2004, we took legal action against the  municipality of Bragança Paulista against the imposition of a 
new  charge  for  the  use  of  public  areas  for  the  installation  of  water  and  sewage  mains  for  the  provision  of  public 
sanitation services.  On February 16, 2005, we were granted an injunction suspending the imposition of this charge 
and  preventing  the  municipality  from  collecting  any  current  or  future  amounts  due  in  respect  of  this  charge  until 
there  is  a  final  decision  on  the  merits.    In  June  2005,  the  lower  court  ruled  in  our  favor  and  the  injunction  was 

93 

 
 
maintained.  The municipality appealed the decision and, as of the date of this annual report, a trial decision was still 
pending.  We have not made any provisions for this proceeding. 

In 2006, the Federal Revenue Service by means of a lawsuit verified the compliance of our fiscal obligations related 
to income and social contribution taxes for 2001, calculating a fiscal credit to the Federal Revenue Service in the 
amount of R$277.0 million.  We filed a response in a timely manner contesting this amount and will appeal against 
the administrative decision by means of an administrative proceeding and a lawsuit.  Based on the opinion of our 
internal legal counsel, approximately 90% of this amount is considered as a remote loss and the remaining 10% as a 
possible loss. 

We  cannot  predict  the  outcome  of  any  of  these  lawsuits  nor  can  we  assure  you  that,  in  the  event  of  an  adverse 
decision, we will be able to pass on to our customers any increase in our deductions from gross revenue, operating 
expenses or other expenses. 

Condemnation Proceedings 

We are party to a significant number of condemnation proceedings arising from the partial or total expropriation or 
use  of  private  property  for  water  mains,  sewer  lines  and  facilities.    Under  Brazilian  law,  the  State  or  the  relevant 
municipality  is  entitled  to  condemn  private  property  to  the  extent  required  for  the  construction,  development  or 
improvement  of  parts  of  water  and  sewage  systems  operated  by  us.    However,  we  are  required  to  provide 
compensation to affected property owners based upon appraised fair market values.  Although we generally provide 
compensation to property owners on the basis of negotiated settlements, we are a party to many lawsuits related to 
compensation awards.  As of December 31, 2006, we estimated that we will be required to make payments totaling 
R$467.0 million with respect to all condemnation matters.  After we make these payments, we will have ownership 
of  the  property,  which  will  be  recorded  as  our  asset.    Therefore,  we  have  not  made  any  provisions  for  these 
proceedings.   

Concession-Related Legal Proceedings 

In  connection  with  discussions  we  had  with  the  municipality  of  Presidente  Prudente,  we  filed  a  claim  against  the 
municipality seeking a court decision determining the continuation of the concession contract that we have entered 
into with that municipality until the indemnification payment owed to us in connection with the return of water and 
sewage  treatment  facility  of  Presidente  Prudente  is  made.    The  lower  court  issued  a  decision  in  our  favor  to  the 
effect  that  we  still  continue  to  provide  services  in  the  municipality  until  the  indemnification  provided  for  in  the 
concession contract is paid to us.   

On March 25, 2004, the Public Attorney’s Office filed a civil action against the municipality of Itapira, its mayor, 
the Municipal House of Representatives and us, claiming that Municipal Law No. 3,593/04 is unconstitutional and 
seeking  termination  of  the  concession  contract  we  entered  into  with  the  municipality  of  Itapira.    Although  an 
injunction was granted, the Court of Justice of the State of São Paulo has stayed the injunction.  On March 23, 2005, 
the House of Representatives of Itapira approved a decree revoking the concession contract.  In addition, Municipal 
Law  No.  3,730/05  was  enacted  revoking  an  earlier  law  which  authorized  the  municipality  to  enter  into  the 
concession contract with us.  The municipality of Itapira has further filed an action against us seeking to repossess 
the assets related to its water and sewage services and has obtained an injunction which was later confirmed by a 
court decision.  We appealed against this ruling but we have not been able to suspend the effects of the decision until 
final judgment.  Accordingly, we are currently not rendering water and sewage services at Itapira.  As of the date of 
this  annual  report,  a  trial  decision  on  this  litigation  was  pending.    We  have  not  made  any  provisions  for  this 
proceeding. 

On October 10, 2003, the municipality of Monte Mor filed a lawsuit against us, seeking the additional issuance and 
delivery of shares by us, as consideration for our concession to render basic water and sewage services.  The lawsuit 
was dismissed without judgment on the merits of the case.  We have not made any provisions for this proceeding. 

The municipality of Sandovalina has brought a legal action against us seeking to (1) obtain the termination of the 
concession entered into with us and (2) obtain remedies for environmental damage and alleged losses caused to the 

94 

 
 
municipality due to our failure to provide sewage treatment, as well as other damage caused to public property.  We 
have  responded  with  a  counterclaim  against  the  municipality  for  payment  of  R$115,000  related  to  the  supply  of 
water from December 1999 through August 2003.  We are also seeking the payment of a contractual indemnification 
based on the early termination of the contract.  We are currently operating the water and sewage treatment facility of 
Sandovalina, and the lawsuit is still in the fact-finding phase.  We have not made any provisions for this proceeding.  

We are also defendants in legal proceedings initiated by municipalities seeking to require us to produce documents 
and  information  in  connection  with  our  concessions.    These  legal  proceedings  include  the  following:    (1)  a 
preliminary proceeding (ação cautelar) started by the municipality of Guariba seeking a court order requiring us to 
produce  documents  in  order  to  inform  an  account  revision  proceeding;  (2)  the  municipality  of  Ribeirão  Pires  has 
proposed  preliminary  proceedings seeking  the production  of documents  to  inspect the  services  which  we  provide; 
(3)  the  municipalities  of  Itupeva  and  Monte  Mor  have  proposed  proceedings  seeking  to  obtain  a  court  order  to 
require us to produce documents and information in order to evaluate the possibility of renewal of our concession 
agreement. 

Tariff-Related Legal Proceedings and Consumers Claims 

We are party to a number of proceedings with the Public Prosecution Office of the State of São Paulo and several 
municipalities which have contested our right to charge a tariff for sewage services provided as opposed to charging 
a fixed fee for these services.  In most of these proceedings, we have received decisions in our favor.  In addition, 
the Superior Court of Justice of Brazil (Superior Tribunal de Justiça) has confirmed the understanding that we have 
the right to charge a tariff for the sewage services we provide. 

Approximately 980  lawsuits have been brought by our commercial customers that claim that their tariff rates should 
be  equal  to  those  of  another  category  of  customers  and,  consequently,  seek  the  reimbursement  of  the  difference 
between the amounts we charged and collected and those tariffs.  We have obtained final decisions both in favor and 
against us in these lawsuits and, as of December 31, 2006, we have established a provision in the amount of R$273.3 
million  with  respect  to  these  lawsuits.    We  cannot  predict,  however,  the  amounts  we  would  have  to  pay  to  these 
customers  if  they  were  to  prevail  in  their  lawsuits,  nor  can  we  provide  assurance  that  new  lawsuits  will  not  be 
brought by other customers on similar grounds. 

The  Association  of  Distinguished  Bars  and  Restaurants  (Associação  de  Bares  e  Restaurantes  Diferenciados—
ABREDI),  has  initiated  several  lawsuits  to  challenge  the  10.0%  penalty  fee  we  charge  on  late  water  and  sewage 
payments.  In several of these cases, lower courts have dismissed the lawsuits based on the lack of standing by the 
plaintiff  to  initiate  such  a  lawsuit.    In  other  cases,  the  lawsuits  were  dismissed  because  a  civil  public  action  with 
respect to the same matter was already being heard at the civil courts of the State of São Paulo.  In this civil public 
action, a decision was granted against us and we appealed against this decision and a final decision is still pending.  
Notwithstanding these legal proceedings, we have reduced to 2.0% the penalty fee we charge on late bill payments 
by all of our customers.   

Contractors’ Claims 

Certain  contractors  have  filed  claims  against  us  alleging  underpayment  of  inflation  indexation  adjustments  and 
monetary losses incurred in connection with introduction of the real.  Based on advice from our legal counsel, as of 
December 31, 2006, we established a provision for these claims in the amount of R$168.5 million to meet probable 
losses arising from unfavorable decisions in these actions. 

Other Legal Proceedings 

We  are  a  party  to  a  series  of  lawsuits  initiated  by  the  municipality  of  Ferraz  de  Vasconcelos  in  1997,  seeking 
payment of penalties in the aggregate amount of R$71.9 million, which we allegedly owe for damages caused during 
construction in the municipality.  Several of these lawsuits have already been rejected by lower courts but are still 
subject to appeal.  We have not made any provisions for these proceedings. 

95 

 
 
In December 1997, the municipality of Santos enacted a law expropriating our water and sewage systems in Santos.  
In  response,  we  filed  an  action  seeking  an  injunction  against  this  expropriation,  which  was  denied  by  the  lower 
court.  This decision was later reversed by the Court of Justice of the State of São Paulo, which issued a preliminary 
order suspending that law.  On August 2, 2002, a decision on this matter was rendered in our favor by a lower court, 
but that decision remains subject to appeal.  Despite the pending lawsuit, we continue to provide water and sewage 
services to Santos.  

We  are  a  party  to  several  administrative  proceedings  with  the  Environmental  Sanitation  Technology  Company 
(Companhia  de  Tecnologia  de  Saneamento  Ambiental)  seeking  the  imposition  of  penalties  for  environmental 
damages  allegedly  caused  by  us  and  other  regulatory  matters.    We  have  not  made  any  provisions  for  these 
proceedings. 

On October 29, 2003, the Public Prosecution Office of the State of São Paulo on behalf of the people of the State of 
São Paulo, brought a civil public action in a trial court of the State of São Paulo (12a. Vara da Fazenda Pública do 
Estado de São Paulo) alleging that a transfer to us of ownership of the Alto Tietê System reservoirs from the State 
Department  of  Water  and  Energy  would  be  illegal.    In  October  2004,  the  court  ruled  in  favor  of  the  Public 
Prosecution  Office  of  the  State  of  São  Paulo,  with  respect  to  the  illegality  of  the  transfer  of  the  reservoirs.    In 
response, we filed an appeal which is pending final decision. 

In December 1996, we filed a claim to collect payment due from the municipality of Diadema.  In December 2005, 
the  Court  of  Justice  of  the  State  of  São  Paulo  ruled  in  our  favor.    This  legal  proceeding  was  followed  by  several 
other related legal proceedings, some of which are currently pending.  A civil public action and an annulment action 
have been decided in our favor.  On October 11, 2006, the municipality of Diadema appealed againts the decision 
and on November 21, 2006 a decision was published allowing us to present our response to the appeal.  We filed our 
response on December 6, 2006. 

We entered into a settlement agreement with the municipality of Mauá at the time the concession was terminated in 
which Mauá agreed to make the payments owed to us in connection with the return of water and sewage treatment 
facilities.  However, to date Mauá has not yet made any payments to us under the settlement agreement.  We filed a 
claim  against  Mauá  in  December  1996  and  a  decision  was  issued  in  February  2005  by  the  lower  court  requiring 
Mauá  to  pay  us  the  amount  of  R$153.2  million.    The  municipality  of  Mauá  and  SAMA–Saneamento  Básico  do 
Município de Mauá appealed this decision.  The appeal is pending final decision by the Court of Justice of the State 
of São Paulo.  On July 4, 2006 the judgement was converted into investigation to clarify the amount related to the 
indemnity.  The technical expert has not yet testified before the court to clarify the value of the indemnity.  Based on 
our internal legal counsel opinion, our management still believes that we have the legal right to receive the amount 
related to the indemnity and we continue to monitor the status of these legal proceedings. 

We  are  a  party  to  a  substantial  number  of  other  legal  proceedings,  in  addition  to  the  lawsuits  and  administrative 
proceedings discussed above, in the normal course of our business.  These legal proceedings include personal injury 
and  property  damage  cases,  environmental  proceedings,  challenges  to  our  ability  to  cease  rendering  water  and 
sewage services upon default by our customers and a range of other  matters.  We have not established provisions 
with respect to these other legal proceedings. 

Dividends and Dividend Policy 

Amounts Available for Distribution 

At  each  annual  shareholders’  meeting,  the  board  of  directors  is  required  to  recommend  how  net  profits  for  the 
preceding  fiscal  year are to be allocated.   For purposes of  Brazilian  Corporate  Law,  net  profits are  defined  as net 
income  after  income  taxes  and  social  contribution  taxes  for  such  fiscal  year,  net  of  any  accumulated  losses  from 
prior  fiscal  years  and  any  amounts  allocated  to  employees’  and  management’s  participation  in  our  profits.    In 
accordance with Brazilian Corporate Law, the amounts available for dividend distribution are the amounts equal to 
our net profits less any amounts allocated from such net profits to: 

• 

the legal reserve; and 

96 

 
 
• 

retained earnings for investment reserve. 

We are required to maintain a legal reserve, to which we must allocate 5% of net profits for each fiscal year until the 
amount for such reserve equals 20% of our paid-in capital.  However, we are not required to make any allocations to 
our  legal  reserve  in  respect  of  any  fiscal  year  in  which  the  aggregate  amount  of  the  legal  reserve  plus  our  other 
established capital reserves exceeds 30% of our capital.  Net losses, if any, may be charged against the legal reserve.  
On  December 31,  2006,  the  balance  of  our  legal  reserve  was  R$254.2 million,  which  was  equal  to  7.6%  of  our 
paid-in capital. 

Brazilian Corporate Law also provides for two discretionary allocations of net profits that are subject to approval by 
the shareholders at the annual meeting.  First, a percentage of net profits may be allocated to a contingency reserve 
for anticipated losses  that are deemed probable  in  future years.   Any amount so allocated in a  prior  year  must  be 
either reversed in the fiscal year in which the loss was anticipated if such loss does not in fact occur, or written off in 
the  event  that  the  anticipated  loss  occurs.    Second,  if  the  mandatorily  distributable  amount  exceeds  the  sum  of 
realized net profits in a given year, such excess may be allocated to an unrealized revenue reserve.  Under Brazilian 
Corporate  Law,  realized  net  profits  is  defined  as  the  amount  of  net  profits  that  exceeds  the  net  positive  result  of 
equity adjustments and profits or revenues from operations with financial results after the end of the next succeeding 
fiscal year. 

Under Brazilian Corporate Law, any company may, as a term in its by-laws, create a discretionary reserve.  By-laws 
which  authorize  the  allocation  of  a  percentage  of  a  company’s  net  income  to  the  discretionary  reserve  must  also 
indicate the purpose, criteria for allocation and maximum amount of the reserve.  We may also allocate a portion of 
our net profits for discretionary appropriations for plan expansion and other capital investment projects, the amount 
of which would be based on a capital budget previously presented by management and approved by shareholders.  
Under Law No. 10,313 of October 3, 2001, capital budgets for more than one year must be revised at each annual 
shareholders’ meeting.  After completion of the relevant capital projects, we may retain the appropriation until the 
shareholders vote to transfer all or a portion of the reserve to capital or retained earnings.  At December 31, 2006, 
we had an investment reserve of R$2,826.4 million. 

The  amounts  available  for  distribution  may  be  further  increased  by  a  reversion  of  the  contingency  reserve  for 
anticipated losses constituted in prior years but not realized.  The amounts available for distribution are determined 
on the basis of financial statements prepared in accordance with the Brazilian Corporate Law Method. 

The legal reserve is subject to approval by the shareholders voting at the annual meeting and may be transferred to 
capital  but  is  not  available  for  the  payment  of  dividends  in  subsequent  years.    Our  calculation  of  net  profits  and 
allocations to reserves for any fiscal year are determined on the basis of financial statements prepared in accordance 
with the Brazilian Corporate Law Method. 

Mandatory Distribution 

Brazilian  Corporate  Law  generally  requires  that  the  by-laws  of  each  Brazilian  corporation  specify  a  minimum 
percentage of the amounts available for distribution by such corporation for each fiscal year that must be distributed 
to shareholders as dividends, also known as the mandatory distributable amount.  Under our by-laws, the mandatory 
distributable  amount  has  been  fixed  at  an  amount  equal  to  not  less  than  25%  of  the  amounts  available  for 
distribution, to the extent amounts are available for distribution. 

The mandatory distribution is based on a percentage of adjusted net income, not lower than 25%, rather than a fixed 
monetary amount per share.  Brazilian Corporate Law, however, permits a publicly held company, such as Sabesp, 
to  suspend  the  mandatory  distribution  of  dividends  if  the  board  of  directors  and  the  conselho  fiscal  report  to  the 
shareholders’ meeting that the distribution would be inadvisable in view of the company’s financial condition.  The 
suspension  is  subject  to  approval  of  holders  of  common  shares.    In  this  case,  the  board  of  directors  must  file  a 
justification  for such suspension with the Brazilian securities commission.  Profits  not distributed by  virtue of the 
suspension mentioned above shall be attributed to a special reserve and, if not absorbed by subsequent losses, must 
be paid as dividends as soon as the financial condition of such company permits such payments.

Payment of Dividends 

We  are  required  by  Brazilian  Corporate  Law  and  by  our  by-laws  to  hold  an  annual  shareholders’  meeting  by  the 
fourth month after the end of each fiscal year at which, among other things, the shareholders have to decide on the 
payment of an annual dividend.  The payment of annual dividends is based on the financial statements prepared for 
the relevant fiscal year.  Under Brazilian Corporate Law, dividends generally are required to be paid within 60 days 
following the date the dividend was declared, unless a shareholders’ resolution sets forth another date of payment, 
which,  in  either  case,  must  occur  prior  to  the  end  of  the  fiscal  year  in  which  the  dividend  was  declared.    A 
shareholder  has  a  three-year  period  from  the  dividend  payment  date  to  claim  dividends  (or  interest  payments  as 
described under “— Record of Dividend Payments and Interest Attributed to Shareholders’ Equity”) in respect of its 
shares,  after  which  the  amount  of  the  unclaimed  dividends  reverts  to  us.    The  depositary  will  set  the  currency 
exchange  date  to  be  used  for  payments  to  ADS  holders  as  soon  as  practicable  upon  receipt  of  those  payments 
from Sabesp. 

Our by-laws do not permit us to pay interim dividends out of preexisting and accumulated profits for the preceding 
fiscal year or semester. 

In general, shareholders who are not residents of Brazil must register with the Central Bank to have dividends, sales 
proceeds or other amounts with respect to their shares eligible to be remitted outside of Brazil.  The common shares 
underlying our ADSs are held in Brazil by Banco Itaú S.A., also known as the custodian, as agent for the depositary, 
which is the registered owner on the records of their registrar for our common shares.  Our current registrar is Banco 
Itaú S.A. The depositary electronically registers the common shares underlying the ADSs with the Central Bank and, 
therefore,  is  able  to  have  dividends,  sales  proceeds  or  other  amounts  with  respect  to  these  shares  eligible  to  be 
remitted outside Brazil.  See “Item 10.D.  Additional Information—Exchange Controls.” 

Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the custodian on behalf 
of  the  depositary,  which  will  then  convert  such  proceeds  into  U.S.  dollars  and  will  cause  such  U.S.  dollars  to  be 
delivered to the depositary for distribution to holders of ADSs.  See “Item 10.D.  Additional Information—Exchange 
Controls.”  Under current Brazilian law, dividends paid to shareholders who are not Brazilian residents, including 
holders of ADSs, will not be subject to Brazilian withholding income tax, except for dividends declared based on 
profits generated prior to December 31, 1995.  See “Item 10.E. Additional Information—Taxation.” 

Record of Dividend Payments and Interest on Shareholders’ Equity 

Brazilian corporations are permitted to distribute dividends in the form of a tax-deductible notional interest expense 
on  shareholders’  equity  in  accordance  with  Law  No.  9,249,  dated  December 26,  1995,  as  amended.    The  rate  at 
which tax-deductible interest may be paid is limited to the product of the average Taxa de Juros de Longo Prazo – 
TJLP (a long-term interest rate published by the Brazilian government) and shareholders’ equity during the relevant 
period and cannot exceed the greater of: 

• 

• 

50%  of  net  income  (before  taking  into  account  such  distribution  and  any  deductions  for  income 
taxes and after taking into account any deductions for social contributions on net profits) for the 
period in respect of which the payment is made; and 

50% of retained earnings.  Any payment of interest on shareholders’ equity to holders of ADSs or 
common  shares,  whether  or  not  they  are  Brazilian  residents,  is  subject  to  Brazilian  withholding 
income tax at the rate of 15% or 25% if the beneficiary is resident in a tax haven.  See “Item 10.E. 
Additional Information—Taxation.”  The amount paid to shareholders as interest on shareholders’ 
equity,  net  of  any  withholding  tax,  may  be  included  as  part  of  any  mandatory  distributable 
amount.  Under Brazilian law, we are obligated to distribute to shareholders an amount sufficient 
to  ensure  that  the  net  amount  received  by  them,  after  payment  by  us  of  applicable  Brazilian 
withholding taxes in respect of the distribution of interest on shareholders’ equity, is at least equal 
to the mandatory distributable amount.  When we distribute interest on shareholders’ equity, and 
that distribution is not accounted for as part of the mandatory distribution, Brazilian withholding 
tax will apply.  All payments to date were accounted for as part of the mandatory distribution.

On  April 28,  June 23,  October 20  and  December 15,  2005,  our  board  of  directors  approved  the  payment  of 
dividends,  in  the  form  of  interest  on  shareholders’  equity,  in  the  amount  of  R$38.2 million,  R$66.8 million, 
R$85.2 million and R$158.1 million respectively, to be paid within 60 days after our 2006 shareholders’ meeting.  
On  April 20  and  December  14,  2006,  our  board  of  directors  approved  the  payment  of  dividends,  in  the  form  of 
interest on shareholders’ equity, in the amount of R$129.6 million and R$141.2 million, respectively.  The payments 
of interest on shareholders’ equity declared in 2006 began being made on June 29, 2007.  

Dividend Policy 

We intend to declare and pay dividends and/or interest on shareholders’ equity, as required by Brazilian Corporate 
Law  and  our  by-laws.    Our  board  of  directors  may  approve  the  distribution  of  interest  on  shareholders’  equity, 
calculated  based  on  our  semiannual  or  quarterly  financial  statements.    The  declaration  of  dividends  is  annual, 
including dividends in excess of the mandatory distribution, and requires approval by the vote of the majority of the 
holders of our common shares.  The amount of any distributions will depend on many factors, such as our results of 
operations,  financial  condition,  cash  requirements,  prospects  and  other  factors  deemed  relevant  by  our  board  of 
directors and shareholders.  Within the context of our tax planning, we may in the future continue determining that it 
is to our benefit to distribute interest on shareholders’ equity. 

8.B. Significant Changes 

We are not aware of any significant changes bearing upon our financial condition since the date of the consolidated 
financial statements included in this annual report.

9.C. Markets 

Trading on the Brazilian Stock Exchanges 

In 2000, the Brazilian stock exchanges were reorganized through the execution of memoranda of understanding by 
the  Brazilian  stock  exchanges.    Pursuant  to  the  memoranda,  all  securities  are  now  traded  only  on  the  São  Paulo 
Stock Exchange, with the exception of electronically traded public debt securities and privatization auctions, which 
are traded on the Rio de Janeiro Stock Exchange.   

If  you  were  to  trade  in  our  common  shares  on  the  São  Paulo  Stock  Exchange,  your  trade  would  settle  in  three 
business  days  after  the  trade  date  without  adjustment  of  the  purchase  price  for  inflation.    The  seller  is  ordinarily 
required to deliver the shares to the exchange on the second business day following the trade date.  Delivery of and 
payment  for  shares  are  made  through  the  facilities  of  the  clearinghouse,  or  Companhia  Brasileira  de 
Liquidação e Custódia. 

The São Paulo Stock Exchange has an electronic trading system that conducts trading from 10:00 a.m. to 5:00 p.m..  
The São  Paulo  Stock  Exchange also permits  trading  from  5:30 p.m. to  7:00  p.m., on  a  differentiated trading  time 
called the “after market”. Trading  on the after  market is  subject to regulatory limits on price volatility and on the 
volume  of  shares  transacted  through  internet  brokers.    There  are  no  specialists  or  officially  recognized  market 
makers for our shares. 

101 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  order  to  better  control  volatility,  the  São  Paulo  Stock  Exchange  adopted  a  “circuit  breaker”  pursuant  to  which 
trading sessions may be suspended for a period of 30 minutes or one hour whenever its main index (the Index of the 
São  Paulo  Stock  Exchange  or  “BOVESPA”)  fall  below  the  limits  of  10%  or  15%,  respectively,  in  relation  to  the 
index registered in the previous trading session. 

The São Paulo Stock Exchange is less liquid than the New York Stock Exchange or other major exchanges in the 
world.  As of December 31, 2006, the aggregate market capitalization of the 394 companies listed on the São Paulo 
Stock Exchange was equivalent to approximately US$722.6 billion and the 10 largest companies listed on the São 
Paulo Stock Exchange represented approximately 51.3% of the total  market capitalization of all  listed companies.  
Although any of the outstanding shares of a listed company may trade on a Brazilian stock exchange, in most cases 
fewer than half of the listed shares are actually available for trading by the public, the remainder being held by small 
groups of controlling persons, by governmental entities or by one principal shareholder.  As of December 31, 2006, 
we  accounted  for  approximately  1%  of  the  market  capitalization  of  all  listed  companies  on  the  São  Paulo 
Stock Exchange. 

Trading  on  Brazilian  stock  exchanges  by  a  holder  not  deemed  to  be  domiciled  in  Brazil  for  Brazilian  tax  and 
regulatory  purposes  (a  “non-Brazilian  holder”)  is  subject  to  certain  limitations  under  Brazilian  foreign  investment 
legislation.    With  limited  exceptions,  non-Brazilian  holders  may  only  trade  on  Brazilian  stock  exchanges  in 
accordance with the requirements of Resolution No. 2,689, of January 26, 2000, of the National Monetary Council.  
Resolution  No. 2,689  requires  that  securities  held  by  non-Brazilian  holders  be  maintained  in  the  custody  of,  or  in 
deposit  accounts  with,  financial  institutions  duly  authorized  by  the  Central  Bank  and  the  Brazilian  securities 
commission.  In addition, Resolution No. 2,689 requires non-Brazilian holders to restrict their securities trading to 
transactions  on  Brazilian  stock  exchanges  or  qualified  over-the-counter  markets.    With  limited  exceptions, 
non-Brazilian  holders  may  not  transfer  the  ownership  of  investments  made  under  Resolution  No. 2,689  to  other 
non-Brazilian holders through a private transaction.  See “Item 10.E Additional Information—Taxation—Brazilian 
Tax Considerations—Taxation of Gains” for a description of certain tax benefits extended to non-Brazilian holders 
who qualify under Resolution No. 2,689. 

Novo Mercado 

Since April 24, 2002, our shares have been listed on the Novo Mercado.  The Novo Mercado is a listing segment 
under  the  São  Paulo  Stock  Exchange  designed  for  the  trading  of  shares  issued  by  companies  that  voluntarily 
undertake  to  abide  by  some  additional  corporate  governance  practices  and  disclosure  requirements  in  addition  to 
those already imposed by Brazilian law.  A company in the Novo Mercado must follow a series of corporate rules 
known  as  “good  practices  of  corporate  governance”.    These  rules  generally  increase  shareholders’  rights  and 
enhance  the  quality  of  information  provided  to  shareholders.    On  April 18,  2002  and  on  June 19,  2006,  our 
shareholders  approved  changes  to  our  by-laws  to  comply  with  the  Novo  Mercado  requirements.    In  addition,  the 
Novo Mercado provides for the creation of a Market Arbitration Chamber for conflicts resolution between investors 
and companies listed in the Novo Mercado. 

In  addition  to  the  obligations  imposed  by  current  Brazilian  law,  a  company  listed  on  the  Novo  Mercado  is 
obligated to: 

• 

• 

• 

• 

• 

• 

issue only voting shares; 

hold public offerings of shares in a manner favoring diversification of the company’s shareholder 
base and broader retail access; 

maintain a minimum free float equal to 25% of the outstanding share capital of the company; 

grant tag along rights for all shareholders in connection with a transfer of control of the company; 

limit the term of all members of the board of directors to two years; 

at least 20% of the members of the board of directors must be independent, as defined under the 
Novo Mercado regulation; 

102 

 
 
• 

• 

• 

• 

prepare annual and  quarterly financial statements, including cash flow statements, in accordance 
with U.S. GAAP or International Accounting Standards; 

disclose  information  on  a  quarterly  basis,  including  insider  share  ownership  and  amount  of  free 
float of shares; 

if  it  elects  to  delist  from  the  Novo  Mercado,  hold  a  tender  offer  by  the  company’s  controlling 
shareholder  (the  minimum  price  of  the  shares  to  be  offered  will  be  determined  by  an  appraisal 
process); and 

make greater disclosure of related party transactions. 

Regulation of Brazilian Securities Markets 

The  Brazilian  securities  markets  are  principally  governed  by  Law  No. 6,385,  of  December 7,  1976,  and  Brazilian 
Corporate  Law,  each  as  amended  and  supplemented,  and  by  regulations  issued  by  the  Brazilian  securities 
commission, which has regulatory authority over the stock exchanges and securities markets generally, the National 
Monetary  Council,  and  by  the  Central  Bank,  which  has  licensing  authority  over  brokerage  firms  and  regulates 
foreign  investment  and  foreign  exchange  transactions.    These  laws  and  regulations,  among  others,  provide  for 
disclosure requirements applicable to issuers of traded securities, protection of minority shareholders and criminal 
penalties  for  insider  trading  and  price  manipulation.    They  also  provide  for  licensing  and  oversight  of  brokerage 
firms  and  governance  of  the  Brazilian  stock  exchanges.    Nevertheless,  the  Brazilian  securities  markets  are  not  as 
highly regulated and supervised as the U.S. securities markets. 

Under  Brazilian  Corporate  Law,  a  company  is  either  public  (companhia  aberta),  such  as  we  are,  or  closely  held 
(companhia fechada).  All public companies, including us, are registered with the Brazilian securities commission 
and are subject to reporting requirements.  A company registered with the Brazilian securities commission may have 
its  securities  traded  on  the  Brazilian  stock  exchanges  or  in  the  Brazilian  over-the-counter  market.    Our  common 
shares  are  listed  and  traded  on  the  São  Paulo  Stock  Exchange  and  may  be  traded  privately  subject  to 
some limitations. 

To  be  listed  on  a  Brazilian  stock  exchange  a  company  must  apply  for  registration  with  the  Brazilian  securities 
commission and the stock exchange where the head office of the company is located. 

We  have  the  option  to  ask  that  trading  in  our  securities  on  the  São  Paulo  Stock  Exchange  be  suspended  in 
anticipation of a material announcement.  Trading may also be suspended on the initiative of the São Paulo Stock 
Exchange or the Brazilian securities commission, among other reasons, based on or due to a belief that a company 
has  provided  inadequate  information  regarding  a  material  event  or  has  provided  inadequate  responses  to  the 
inquiries by the Brazilian securities commission or the São Paulo Stock Exchange. 

The Brazilian over-the-counter market consists of direct trades between individuals in which a financial institution 
registered  with  the  Brazilian  securities  commission  serves  as  intermediary.    No  special  application,  other  than 
registration with the Brazilian securities commission, is necessary for securities of a public company to be traded in 
this  market.    The  Brazilian  securities  commission  requires  that  it  be  given  notice  of  all  trades  carried  out  in  the 
Brazilian over-the-counter market by the respective intermediaries. 

Trading on the São Paulo Stock Exchange by non-residents of Brazil is subject to limitations under Brazilian foreign 
investment and tax legislation.  The Brazilian custodian for the common shares underlying the ADSs must, on behalf 
of the depositary for our ADSs, obtain registration from the Central Bank to remit U.S. dollars abroad for payments 
of dividends, any other cash distributions, or upon the disposition of the shares and sales proceeds thereto.  In the 
event that a holder of ADSs exchanges ADSs for common shares, the holder will be entitled to continue to rely on 
the  custodian’s  registration  for  five  business  days  after  the  exchange.    Thereafter,  the  holder  may  not  be  able  to 
obtain  and  remit  U.S.  dollars  abroad  upon  the  disposition  of  our  common  shares,  or  distributions  relating  to  our 
common shares, unless the holder  obtains  a new registration.   See  “Item 10.D Additional Information—Exchange 
Controls.”

10.B. Memorandum and Articles of Association 

The following is a summary of the material terms of our common shares, including related provisions of our by-laws 
and Brazilian Corporate Law.  This description is qualified by reference to our by-laws and to Brazilian law. 

Corporate Purposes 

We  are  a  mixed  capital  company  duly  organized  under  the  laws  of  Brazil  with  unlimited  duration.    We  have  the 
legal  status  of  a  sociedade  de  economia  mista,  a  mixed  capital  company  with  limited  liability,  operating  under 
Brazilian Corporate Law.  As set forth in Article 2 of our by-laws, our corporate purpose is to plan, execute, operate 
and market basic sanitation services and their connected benefits throughout the territory of the State of São Paulo.  
Since March 2006, we are also authorized to provide such services in all national territory and abroad. 

Description of Common Shares 

General 

Each  common  share  entitles  the  holder  thereof  to  one  vote  at  our  annual  and  special  shareholders’  meetings.  
Brazilian  Corporate  Law  requires  that  all  our  shareholders’  meetings  be  called  by  publication  of  a  notice  in  the 
Diário  Oficial  do  Estado  de  São  Paulo,  the  official  government  publication  of  the  State  of  São  Paulo,  and  in  a 
newspaper  of  general  circulation  in  our  principal  place  of  business,  currently  the  City  of  São  Paulo,  at  least 
fifteen days prior to the meeting.  In addition, the Brazilian Securities Commission may also require the first call for 
a shareholders’ meeting to be up to 30 days before such shareholders’ meeting.  The quorum to hold shareholders’ 
meetings on first call is generally 25% of the shares entitled to vote and on second call the meetings can be held with 
the presence of any number of the shares entitled to vote. 

Under Brazilian Corporate Law, our common shares are entitled to dividends or other distributions made in respect 
of  our  common  shares  in  proportion  to  their  share  of  the  amount  available  for  the  dividend  or  distribution.    See 
“Item 8.A  Financial  Information—Consolidated  Statements  and  Other  Financial  Information—Dividends  and 
Dividend Policy” for a more complete description of payment of dividends and other distributions on our common 
shares.  In addition, upon any liquidation of Sabesp, our common shares are entitled to return of capital in proportion 
to their share of our net worth. 

In  principle,  a  change  in  shareholder  rights  of  shareholders,  such  as  the  reduction  of  the  compulsory  minimum 
dividend, is subject to a favorable vote of the shareholders representing at least one half of our voting shares.  Under 

104 

 
 
 
some circumstances that may result in a change in the rights of shareholders, such as the creation of preferred shares, 
Brazilian Corporate Law requires the approval of a majority of the shareholders who would be adversely affected by 
the  change  present  in  a  special  meeting  called  for  such  reason.    Brazilian  Corporate  Law  specifies  other 
circumstances where the dissenting shareholder may also have appraisal rights. 

According  to  Brazilian  Corporate  Law,  neither  a  company’s  by-laws  nor  actions  taken  at  a  general  meeting  of 
shareholders may deprive a shareholder of some specific rights, such as: 

• 

• 

• 

• 

• 

the right to participate in the distribution of profits; 

the  right  to  participate  equally  and  ratably  in  any  remaining  residual  assets  in  the  event  of 
liquidation of the company; 

the right to supervise the management of the corporate business as specified in Brazilian Corporate 
Law; 

the right to preemptive rights in the event of a subscription of shares, debentures convertible into 
shares or subscription bonuses  (except in some specific circumstances under Brazilian law); and 

the right to withdraw from the company in the cases specified in Brazilian Corporate Law. 

Pursuant to Brazilian Corporate Law and our by-laws, each of our common shares carries the right to one vote at a 
general meeting of shareholders.  Sabesp may not restrain or deny that right without the consent of the holders of a 
majority of the shares affected. 

Neither Brazilian Corporate Law nor our by-laws expressly addresses: 

• 

• 

• 

staggered terms for directors; 

cumulative voting, except as described below; or 

measures that could prevent a takeover attempt. 

However, under the laws of the State of São Paulo and our by-laws, the State is required to own at least a majority of 
our outstanding common shares. 

According to Brazilian Corporate Law, shareholders representing at least one-tenth of the voting capital may request 
that a multiple voting procedure be adopted to entitle each share to as many votes as there are board members and to 
give each shareholder the right to vote cumulatively for only one candidate or to distribute their votes among several 
candidates.  Pursuant to Brazilian Corporate Law, shareholder action must be taken at a shareholders meeting duly 
called and not by written consent. 

Preemptive Rights 

Each of our shareholders has a general preemptive right to subscribe for shares or securities convertible into shares 
in any capital increase, in proportion to its shareholding, except in the event of the grant and exercise of any option 
to acquire shares of our share capital.  A period of at least 30 days following the publication of notice of the issuance 
of shares or securities convertible into shares is allowed for exercise of the right, and the right is negotiable.  Under 
Brazilian Corporate Law, we may amend our by-laws to eliminate preemptive rights or to reduce the exercise period 
in connection with a public offering of shares or an exchange offer made to acquire another company.  Currently our 
by-laws provide our shareholders with preemptive rights with respect to any offering. 

In the event of a capital increase by means of the issuance of new shares, holders of ADSs, or of common shares, 
would, except under circumstances described above, have preemptive rights to subscribe for any class of our newly 
issued shares.  However, an ADS holder may not be able to exercise the preemptive rights relating to the common 

105 

 
 
shares underlying his or her ADSs unless a registration statement under the Securities Act is effective with respect to 
those  rights  or an exemption  from the  registration requirements of  the Securities  Act is  available.   See  “Item 3.D. 
Key  Information—Risk  Factors—Risks  Relating  to  Our  Common  Shares  and  ADSs—A  holder  might  be  unable  to 
exercise preemptive rights and tag-along rights with respect to the common shares.” 

Redemption and Rights of Withdrawal 

Brazilian Corporate Law provides that, under limited circumstances, a shareholder has the right to withdraw his or 
her equity interest from the company and to receive payment for the portion of shareholder’s equity attributable to 
his or  her equity interest.  This  right of withdrawal  may be exercised by dissenting shareholders of  Sabesp in the 
event that at least half of all voting shares outstanding authorize us: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

to create preferred shares; 

to reduce the mandatory distribution of dividends; 

to merge into another company or to consolidate with another company, subject to the conditions 
set forth in Brazilian Corporate Law; 

to participate in a centralized group of companies as defined under Brazilian Corporate Law and 
subject to the conditions set forth therein; 

to change our corporate purpose; 

to split up, subject to the conditions set forth in Brazilian Corporate Law; 

to transform into another type of company; 

to transfer all of our shares to another company or to receive shares of another company in order to 
make  the  company  whose  shares  are  transferred  a  wholly  owned  subsidiary  of  such  company, 
known as incorporação de ações; or 

to  acquire  control  of  another  company  at  a  price  which  exceeds  the  limits  set  forth  in  Brazilian 
Corporate Law. 

The right of withdrawal lapses 30 days after publication of the minutes of the shareholders’ meeting that approved 
the  corporate  actions  described  above.    We  would  be  entitled  to  reconsider  any  action  giving  rise  to  withdrawal 
rights within 10 days following the expiration of such rights if the withdrawal of shares of dissenting shareholders 
would jeopardize our financial stability.  Brazilian Corporate Law allows companies to redeem their shares at their 
economic value, subject to the provisions of their by-laws and certain other requirements.  Our by-laws currently do 
not  provide  that  our  capital  stock  will  be  redeemable  at  its  economic  value  and,  consequently,  any  redemption 
pursuant to Brazilian Corporate Law would be made based on the book value per share, determined on the basis of 
the last balance sheet approved by the shareholders.  However, if a shareholders’ meeting giving rise to redemption 
rights occurred more than 60 days after the date of the last approved balance sheet, a shareholder would be entitled 
to  demand  that  his  or  her  shares  be  valued  on  the  basis  of  a  new  balance  sheet  dated  within  60 days  of  such 
shareholders’ meeting. 

In  addition,  the  rights  of  withdrawal  in  the  third,  fourth  and  eighth  bullet  points  above  may  not  be  exercised  by 
holders of shares if such shares (1) are liquid, defined as being part of the São Paulo Stock Exchange Index or other 
stock  exchange  index  (as  defined  by  the  Brazilian  securities  commission),  and  (2) are  widely  held,  such  that  the 
controlling shareholder or companies it controls have less than 50% of our shares.  Our common shares are included 
on the São Paulo Stock Exchange Index. 

106 

 
 
This right of withdrawal may also be exercised in the event that the entity resulting from a merger, incorporação de 
ações,  as  described  above,  consolidation  or  spin-off  of  a  listed  company  fails  to  become  a  listed  company  within 
120 days of the shareholders’ meeting at which such decision was taken. 

Arbitration 

In connection with our listing with the Novo Mercado, we, our controlling shareholders, directors and officers have 
undertaken to refer to arbitration any and all disputes or controversies arising out of the Novo Mercado rules or any 
other corporate matters.  See “Item 9.C. The Offer and Listing—Markets.”  Under our by-laws, any disputes among 
us,  our  shareholders  and  our  management  with  respect  to  the  application  of  Novo  Mercado  rules,  Brazilian 
Corporate Law, the application of the rules and regulations regarding Brazilian capital markets, will be resolved by 
arbitration  conducted  pursuant  to  the  BOVESPA  Arbitration  Rules  in  the  BOVESPA  Arbitration  Chamber.    Any 
disputes  among  shareholders,  including  holders  of  ADSs,  and  disputes  between  us  and  shareholders,  including 
holders of ADSs, will also be submitted to arbitration. 

Options 

There are currently no outstanding options to purchase any of our common shares. 

Directors’ Powers 

Although our by-laws contain no specific provisions regarding a director or executive officer’s power to vote on a 
proposal,  arrangement or  contract in which  that  director has a  material interest,  under  Brazilian Corporate Law,  a 
director or an executive officer is prohibited from voting in any meeting or with respect to any transaction in which 
that director or executive officer has a conflict of interest with the company and must disclose the nature and extent 
of  the  conflicting  interest  for  transcription  in  the  minutes  of  the  meeting.    In  any  case,  a  director  or  an  executive 
officer may not transact any business with the company, including any borrowing, except on reasonable or fair terms 
and conditions that are identical to the terms and conditions prevailing in the market or offered by third parties. 

Under our by-laws our shareholders are responsible for establishing the compensation we pay to the members of our 
board of directors and the executive officers. 

Pursuant to Brazilian Corporate Law, each member of our board of directors must be a shareholder of Sabesp and, 
pursuant to our by-laws, a resident of Brazil.  Our by-laws do not establish any mandatory retirement age limits. 

See also “Item 6.A. Directors and Senior Management.” 

10.C. Material Contracts 

For a description of the material contracts entered into by Sabesp and the State, see “Item 7. Major Shareholders and 
Related  Party  Transactions—Related  Party  Transactions—Transactions  with  the  State  of  São  Paulo—Agreements 
with the State.” 

10.D. Exchange Controls 

There are no restrictions on ownership of common shares by individuals or legal entities domiciled outside Brazil.  
However,  the  right  to  convert  dividend  payments  and  proceeds  from  the  sale  of  common  shares  into  foreign 
currency  and  to  remit  such  amounts  outside  Brazil  is  subject  to  restrictions  under  foreign  investment  legislation 
which generally requires, among other things, the registration of the relevant investment with the Central Bank. 

Pursuant to Brazilian law, investors may invest in common shares under Resolution 2,689, of January 26, 2000, of 
the National Monetary Council. 

Resolution No. 2,689 allows non-Brazilian investors to invest in almost all financial assets and to engage in almost 
all  transactions  available  in  the  Brazilian  financial  and  capital  markets,  provided  that  some  requirements  are 

107 

 
 
fulfilled.    In  accordance  with  Resolution  No.  2,689,  the  definition  of  non-Brazilian  investor  includes  individuals, 
legal entities, mutual funds and other collective investment entities, domiciled or headquartered outside of Brazil. 

Pursuant to Resolution 2,689, a foreign investor must:  (1) appoint at least one representative in Brazil with powers 
to perform actions relating to the foreign investment; (2) complete the appropriate foreign investor registration form; 
(3) register  as a  foreign  investor with  the  Brazilian securities commission; and (4) register  the  foreign  investment 
with the Central Bank. 

Securities  and  other  financial  assets  held  by  foreign  investors  pursuant  to  Resolution  2,689  must  be  registered  or 
maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or the Brazilian 
securities commission. In addition, securities trading is restricted to transactions carried out in the stock exchanges 
or organized over-the-counter markets licensed by the Brazilian securities commission, except for transfers resulting 
from  a  corporate  reorganization,  occurring  upon  the  death  of  an  investor  by  operation  of  law  or  will  or  as  a 
consequence of the de-listing of the relevant shares from a stock exchange and the cancellation of the registration 
with the Brazilian securities commission. 

Under Resolution No. 2,689, foreign investors registered with the Brazilian securities commission may buy and sell 
shares on the São Paulo Stock Exchange without obtaining a separate certificate of registration for each transaction.  
Investors under these regulations are also generally entitled to favorable tax treatment. 

Annex  V  to  Resolution  No. 1,289,  as  amended,  of  the  National  Monetary  Council,  also  known  as  the  Annex  V 
Regulations,  provides  for  the  issuance  of  depositary  receipts  in  foreign  markets  in  respect  of  shares  of 
Brazilian issuers. 

Following the closing of the sale of our ADSs in May 2002, an electronic certificate of registration was made in the 
name  of  The  Bank  of  New  York,  as  the  depositary,  with  respect  to  such  ADSs  and  will  be  maintained  by  the 
Brazilian  custodian  for  our  common  shares  on  behalf  of  the  depositary.    This  electronic  registration  is  carried  on 
through the Central Bank Information System.  Pursuant to the registration, the custodian and the depositary are able 
to  convert  dividends and other  distributions with  respect to  the  common shares represented by ADSs  into  foreign 
currency  and  remit  the  proceeds  outside  Brazil.    In  the  event  that  a  holder  of  ADSs  exchanges  such  ADSs  for 
common shares, the holder will be entitled to continue to rely on such electronic registration for five business days 
after  the  exchange.    Thereafter,  unless  our  common  shares  are  held  pursuant  to  Resolution  No. 2,689  by  a  duly 
registered investor, or, if not a registered investor under Resolution No. 2,689, a holder of common shares applies 
for and obtains a new certificate of registration from the Central Bank, the holder may not be able to convert into 
foreign currency and remit outside Brazil the proceeds from the disposition of, or distributions with respect to, our 
common  shares,  and  the  holder,  if  not  registered  under  Resolution  No. 2,689,  will  be  subject  to  less  favorable 
Brazilian  tax  treatment  than  a  holder  of  ADSs.    In  addition,  if  the  foreign  investor  resides  in  a  “tax  haven” 
jurisdiction, the investor will be also subject to less favorable tax treatment. 

See “Item 3.D. Key Information—Risk Factors—Risks Relating to Our Common Shares and ADSs—Investors who 
exchange ADSs for common shares may lose their ability to remit foreign currency abroad and to obtain Brazilian 
tax advantages” and “Item 10.E. Taxation—Brazilian Tax Considerations.” 

10.E. Taxation 

This summary contains a description of certain Brazilian and U.S. federal income tax consequences of the purchase, 
ownership and disposition of common shares or ADSs by a holder. 

The summary is based upon the tax laws of Brazil and the federal income tax laws of the United States as in effect 
on  the  date  of  this  annual  report,  which  are  subject  to  change,  possibly  with  retroactive  effect,  and  to  differing 
interpretations.  Holders of common shares or ADSs should consult their own tax advisors as to the Brazilian, U.S. 
or  other  tax  consequences  of  the  purchase,  ownership  and  disposition  of  common  shares  or  ADSs,  including,  in 
particular, the effect of any non-Brazilian, non-U.S., state or local tax laws. 

108 

 
 
Although  there  presently  is  no  income  tax  treaty  between  Brazil  and  the  United  States,  the  tax  authorities  of  the 
two countries have had discussions in the past regarding such a treaty.  No assurance can be given, however, as to if 
or when a treaty will enter into force or how it will affect the U.S. holders of common shares or ADSs. 

Brazilian Tax Considerations 

The  following  discussion  summarizes  the  principal  Brazilian  tax  consequences  of  the  acquisition,  ownership  and 
disposition of common shares or ADSs by a holder that is not domiciled in Brazil for purposes of Brazilian taxation 
(a “non-Brazilian holder”).  It is based on Brazilian law as currently in effect, and, therefore, any change in such law 
may change the consequences described below.  Each non-Brazilian holder should consult his or her own tax adviser 
concerning the Brazilian tax consequences of an investment in common shares or ADSs. 

A  non-Brazilian  holder  of  ADSs  may  withdraw  them  in  exchange  for  common  shares  in  Brazil.    Pursuant  to 
Brazilian law, the non-Brazilian holder may invest in the common shares  under Resolution 2,689, of January 26, 
2000, of the National Monetary Council (“2,689 holder”). 

Taxation of Dividends 

As a result of the tax legislation adopted on December 26, 1995, dividends based on profits generated after January 
1, 1996, including dividends  paid in kind,  payable by us in respect  of common  shares  or ADSs,  are exempt  from 
withholding income tax.  Dividends relating to profits generated prior to January 1, 1996 may be subject to Brazilian 
withholding income tax at varying rates, depending on the year the profits were generated.  

Taxation of Gains 

Gains realized outside Brazil by a non-Brazilian holder on the disposition of ADSs to another non-Brazilian holder 
are not currently subject to Brazilian tax. However, according to Law No. 10,833 of December 2003, or Law No. 
10,833, the disposition of assets located in Brazil by a non-Brazilian holder, whether to other non-Brazilian holder 
or  Brazilian  holders,  may  become  subject  to  taxation  in  Brazil.    Although  we  believe  that  the  ADSs  do  not  fall 
within  the  definition  of  assets  located  in  Brazil  for  the  purposes  of  Law  No.  10,833,  considering  the  general  and 
unclear  scope  of  it  and  the  lack  of  judicial  court  ruling  in  respect  thereto,  we  are  unable  to  predict  whether  such 
understanding will ultimately prevail in the courts of Brazil. 

Thus, the gain on disposition of ADSs by a non-Brazilian holder to a resident in Brazil (or even to a non Brazilian 
resident in case the argument above does not prevail) may be subject to income tax in Brazil according to the rules 
described below for ADSs or the tax rules applicable to common shares, as applicable. 

The withdrawal of ADSs in exchange for common shares is not subject to Brazilian income tax provided that the 
regulatory rules are appropriately observed in respect to the registration of the investment before the Central Bank of 
Brazil.  The deposit of common shares in exchange for ADSs may be subject to Brazilian capital income tax at the 
rate of 15% or 25%, in case the non-Brazilian holder is located in a tax haven, i.e. considered to be places which do 
not  impose  any  income  tax  at  a  maximum  rate  of  less  than  20%  and  those  where  the  internal  legislation  imposes 
restrictions on disclosure of the shareholding composition or the ownership of the investment (“tax haven holder”), 
if the acquisition cost of the common shares is lower than (1) the average price per common share on a Brazilian 
stock exchange on which the greatest number of such shares were sold on the day of deposit, or (2) if no common 
shares  were  sold  on  that  day,  the  average  price  on  the  Brazilian  stock  exchange  on  which  the  greatest  number  of 
common  shares  were  sold  in  the  fifteen  trading  sessions  immediately  preceding  such  deposit.    In  this  case,  the 
difference between the acquisition cost and the average price of the common shares, calculated as above, shall be 
considered a capital gain. 

Gains realized on disposition of common shares, are subject to income tax in Brazil, regardless of whether the sale 
or the disposition is made by the non-Brazilian holder to a resident or person domiciled in Brazil or not, based on the 
fact that the common shares could be considered as assets located in Brazil for purposes of Law No. 10,833. 

109 

 
 
Thus, for purposes of taxation of gains earned in a sale or disposition of common shares carried out on the Brazilian 
stock exchange (which includes the transactions carried out on the organized over-the-counter market): 

• 

• 

are exempt from  income tax when assessed by a 2,689 holder and is not a tax haven holder; and 

are subject to income tax at a rate of 15% in any other case, including gains assessed by a non-
Brazilian holder that (1) is not a 2,689 holder, or (2) is a 2,689 holder but is a tax haven holder. In 
these  cases,  a  withholding  income  tax  of  0.005%  shall  be  applicable  and  can  be  offset  with  the 
eventual income tax due on the capital gain. 

Any  other  gains  assessed  on  the  disposition  of  the  common  shares  that  are  not  carried  out  on  the  Brazilian  stock 
exchange  are  subject  to  income  tax  a  rate  of  15%,  except  for  tax  haven  holder  which,  in  this  case,  is  subject  to 
income tax at a rate of 25%. In case these gains are related to transactions conducted on the Brazilian non-organized 
over-the-counter market with intermediation, the withholding income tax of 0,005% shall also be applicable and can 
be offset with the eventual income tax due on the capital gain. 

In the case of redemption of securities or capital reduction by a Brazilian corporation, such as ourselves, the positive 
difference  between the  amount  effectively received by the non-Brazilian holder and  the corresponding acquisition 
cost  is  treated,  for  tax  purposes,  as  capital  gain  derived  from  disposition  of  common  shares  not  carried  out  on  a 
Brazilian  stock  exchange  market,  and  is  therefore  subject  to  income  tax  at  the  rate  of  15%  or  25%,  as  the  case 
may be. 

Any exercise of preemptive rights relating to the common shares will not be subject to Brazilian income tax.  Any 
gain  on  the  sale  or  assignment  of  preemptive  rights  relating  to  the  common  shares  by  a  non-Brazilian  holder  of 
common shares or ADSs will be subject to Brazilian taxation at the same rate applicable to the sale or disposition of 
common shares. 

There  is  no  assurance  that  the  current  preferential  treatment  for  holders  of  ADSs  and  non-Brazilian  holders  of 
common  shares  under  Resolution  2,689  will  continue  in  the  future  or  that  it  will  not  be  changed  in  the  future.  
Reductions in the rate of tax provided for by Brazil’s tax treaties do not apply to the tax on gains realized on sales or 
exchange of common shares. 

Interest Attributed to Shareholders’ Equity 

Distribution  of  an  interest  on  equity  charge  attributed  to  shareholders’  equity  in  respect  of  the  common  shares  or 
ADSs  as  an  alternative  form  of  payment  to  shareholders,  including  non-Brazilian  holders  of  common  shares  or 
ADSs, is subject to Brazilian withholding income tax at the rate of 15% or 25%, in case of a tax-haven holder.  Such 
payments, subject to certain limitations and requirements, are deductible for Brazilian income tax purposes. 

Other Brazilian Taxes 

There  are  no  Brazilian  inheritance,  gift  or  succession  taxes  applicable  to  the  ownership,  transfer  or  disposition  of 
common shares or ADSs by a non-Brazilian holder, except for gift and inheritance taxes, which are levied by some 
states of Brazil on gifts made or inheritances bestowed by a non-Brazilian holder to individuals or entities resident 
or domiciled within such states in Brazil.  There are no Brazilian stamp, issue, registration, or similar taxes or duties 
payable by a non-Brazilian holder of common shares or ADSs. 

Tax on Bank Account Transaction, or CPMF 

As a general rule, CPMF is imposed on debits to bank accounts at a current rate of 0.38%.  Therefore, transactions 
by the depositary or by holders of common shares which involve the transfer of Brazilian currency through Brazilian 
financial institutions shall be subject to the CPMF tax.  In some cases, transactions involving foreign investors may 
be exempt from CPMF.  Additionally, according to article 4th of Provisory Measure No. 281, dated as of February 
15th, 2006, the CPMF rate is reduced to zero on withdrawals from bank accounts used to buy commons shares in a 
public offering, provided the public offering is registered with the CVM and that the issuer is listed in the Brazilian 

110 

 
 
stock  exchange.  This  Provisory  Measure  is  currently  valid  but  it  must  be  approved  by  the  Congress  before  it 
becomes a law and is signed by the President.  The responsibility for the collection of the CPMF tax is borne by the 
financial institution that carries out the relevant financial transaction. 

In addition, according to section 4 of the Provisory Measure No. 281, dated February 15, 2006, which is currently in 
effect, the CPMF rate is reduced to zero on withdrawals from bank accounts used to buy common shares in a public 
offering, provided that (1) the public offering is registered with the CVM and (2) the issuer is listed on the Brazilian 
stock exchange.  In order for the effects of this Provisory Measure to become permanent, it must be converted into 
law pursuant to the applicable legal procedures. 

Taxation of Foreign Exchange Transactions, or IOF/Câmbio 

IOF/Câmbio  may  be  imposed  on  the conversion  of  Brazilian  currency into  foreign  currency (e.g., for purposes of 
paying  dividends  and  interest)  and  on  the  conversion  of  foreign  currency  into  Brazilian  currency.    Except  under 
specific circumstances, the rate of IOF/Câmbio tax on such conversions is currently 0%, but the Minister of Finance 
has the legal power to increase at any time the rate to a maximum of 25%, but only in relation to future transactions. 

Tax on Bonds and Securities Transactions, or IOF/Títulos 

The IOF/Títulos may be imposed on any transactions involving bonds and securities, including those carried out on 
Brazilian futures and commodities stock exchanges.  As a general rule, the rate of this tax for transactions involving 
common shares or ADSs is currently zero, although the executive branch may increase such rate up to 1.5% per day, 
but only with respect to future transactions. 

United States Tax Considerations 

The summary discussion below is applicable to you only if you are a U.S. holder that is not domiciled in Brazil (or 
domiciled or resident in a tax haven jurisdiction) for purposes of Brazilian taxation and, in the case of a holder of 
common  shares,  that  has  registered  its  investment  in  common  shares  with  the  Central  Bank  as  a  U.S.  dollar 
investment.    A  U.S.  holder  is  a  beneficial  owner  of  a  common  share  or  ADS  that,  for  U.S.  federal  income  tax 
purposes, is: 

• 

• 

• 

• 

a citizen or resident of the United States; 

a  corporation  created  or  organized  in  or  under  the  laws  of  the  United  States  or  any  political 
subdivision of the United States; 

an estate the income of which is subject to United States federal income taxation regardless of its 
source; or 

a trust if it (1) is subject to the primary supervision of a court within the United States and one or 
more  United  States  persons  have  the  authority  to  control  all  substantial  decisions  of  the  trust  or 
(2) has a valid election in effect under applicable United States Treasury regulations to be treated 
as a United States person. 

Except where noted, this summary deals only with common shares or ADSs held as capital assets and does not deal 
with special situations, such as those of banks, dealers in securities or currencies, traders in securities that elect to 
use a mark-to-market method of accounting for their securities holdings, financial institutions, tax-exempt entities, 
insurance companies, real estate investment trusts, regulated investment companies, persons holding common shares 
or ADSs as part of a hedging, integrated, conversion or constructive sale transaction or a straddle, persons liable for 
alternative minimum tax, pass-through entities and investors in a pass-through entity, persons owning 10% or more 
of our voting stock, or persons whose “functional currency” is not the U.S. dollar.  Furthermore, this discussion set 
forth  under  “United  States  Taxation”  is  based  upon  the  provisions  of  the  Internal  Revenue  Code  of  1986,  as 
amended,  or  the  Code,  and  regulations,  rulings  and  judicial  decisions  thereunder  as  of  the  date  hereof,  and  such 
authorities may be repealed, revoked or modified so as to result in United States federal income tax consequences 

111 

 
 
different from those discussed below possibly with retroactive effect.  In addition, such summary is based, in part, 
upon  representations  made  by  the  Depositary  to  us  and  assumes  that  the  deposit  agreement,  and  all  other  related 
agreements, will be performed in accordance with their terms. 

If a partnership holds common shares or ADSs, the tax treatment of a partner will generally depend upon the status 
of the partner and the activities of the partnership.  If you are a partner of a partnership holding common shares or 
ADSs, you should consult your tax advisors. 

ADSs 

In general, for United States federal income tax purposes, U.S. holders of ADSs will be treated as the owners of the 
underlying common shares that are represented by such ADSs.  Deposits or withdrawals of common shares by U.S. 
holders for ADSs will not be subject to United States federal income tax.  However, the United States Treasury has 
expressed  concerns  that  parties  involved  in  transactions  wherein  depositary  shares  are  pre-released may  be  taking 
actions  that  are  inconsistent  with  the  claiming  of  foreign  tax  credits  by  the  holders  of  ADSs.    Accordingly,  the 
analysis of the creditability of Brazilian taxes described herein could be affected by future actions that may be taken 
by the United States Treasury. 

Taxation of Dividends 

The gross amount of distributions paid to you (including amounts withheld by the Brazilian taxing authority, if any, 
and any payments of interest on shareholders’ equity, as described above under “—Brazilian Tax Considerations”) 
will  be  treated  as  dividend  income  to  the  extent  paid  out  of  our  current  or  accumulated  earnings  and  profits,  as 
determined under United States federal income tax principles.  Such income may be included in your gross income 
as ordinary income when actually or constructively received by you, in the case of common shares, or when actually 
or  constructively  received  by  the  Depositary,  in  the  case  of  ADSs.    Such  dividends  will  not  be  eligible  for  the 
dividends  received  deduction  allowed  to  corporations  under  the  Code.    To  the  extent  that  the  amount  of  any 
distribution exceeds our current and accumulated earnings and profits for a taxable year, the distribution will first be 
treated  as  a  tax-free  return  of  capital  to  the  extent  of  the  U.S.  holders  tax  basis  in  the  common  shares  or  ADS, 
causing a reduction in the adjusted basis of our common shares or ADSs (thereby increasing the amount of gain, or 
decreasing the amount of loss, to be recognized on a subsequent disposition of our common shares or ADSs), and 
thereafter, as capital gain recognized on a sale or exchange. 

The  amount  of  any  dividend  paid  in  reais  will  equal  the  U.S.  dollar  value  of  the  reais  received  calculated  by 
reference to the exchange rate in effect on the date the dividend is received by you, in the case of common shares, or 
by the Depositary, in the case of ADSs, regardless of whether the reais are converted into U.S. dollars.  If the reais 
received as a dividend are not converted into U.S. dollars on the date of receipt, you will have a basis in the reais 
equal to their U.S. dollar value on the date of receipt.  Any gain or loss realized on a subsequent conversion or other 
disposition of the reais will be treated as United States source ordinary income or loss. 

Certain dividends received by certain non-corporate U.S. Holders through taxable years beginning on or before 31 
December  2010  are  subject  to  a  reduced  maximum  tax  rate  of  15%  so  long  as  (1)  specified  holding  period 
requirements are met, (2) the U.S. Holder is not under an obligation (whether pursuant to a short sale or otherwise) 
to  make  related  payments  with  respect  to  positions  in  substantially  similar  or  related  property,  (3)  the  company 
paying  the  dividend  is  a  “qualified  foreign  corporation”  and  (4)  the  company  is  not  a  passive  foreign  investment 
company for U.S. federal income tax purposes (a “PFIC”) in the year of distribution or the prior year.  We do not 
believe that we were classified as a PFIC for our prior taxable year nor do we expect to be classified as a PFIC.  We 
generally  will  be  treated  as  a  qualified  foreign  corporation  with  respect  to  our  ADSs  so  long  as  the  ADS  remain 
listed  on  the  New  York  Stock  Exchange.    Based  on  existing  guidance,  it  is  not  entirely  clear  whether  dividends 
received  with  respect  to  the  common  shares  (to  the  extent  not  represented  by  ADSs)  will  be  treated  as  qualified 
dividend  income,  because  the  common  shares  are  not  themselves  listed  on  a  U.S.  exchange.    You  should  consult 
your own advisor about the application of this rate to dividends paid directly on common shares. 

Subject  to  certain  limitations,  Brazilian  withholding  taxes  on  dividends,  if  any,  may  be  treated  as  foreign  taxes 
eligible for credit against a U.S. holder’s United States federal income tax liability.  Alternatively, at a U.S. holder’s 
election if it does not elect to claim a foreign tax credit for any foreign taxes paid during the taxable year, all foreign 

112 

 
 
income  taxes  paid  may  instead  be  deducted  in  computing  such  U.S.  holder’s  taxable  income.    For  purposes  of 
calculating  the  foreign  tax  credit,  dividends  paid  on  our  common  shares  will  be  treated  as  income  from  sources 
outside the United States.  The limitation on foreign taxes eligible for credit is calculated separately with respect to 
specific  classes  of  income.    Special  rules  apply  to  certain  individuals  whose  foreign  source  income  during  the 
taxable  year  consists  entirely  of  “qualified  passive  income”  and  whose  creditable  foreign  taxes  paid  or  accrued 
during the taxable year do not exceed US$300 (US$600 in the case of a joint return).  Further, a U.S. holder that 
(q) has held common shares or ADSs for less than a specific minimum period during which it is not protected from 
risk of loss or (2) is obligated to make payments related to the dividends will not be allowed a foreign tax credit for 
foreign  taxes  imposed  on  dividends  paid  on  common  shares  or  ADSs.    In  addition,  a  U.S.  holder  that  holds  the 
shares  in  certain  arrangements  in  which  the  U.S.  holder’s  expected  economic  profits  are  insubstantial  may  not  be 
allowed a foreign tax credit for such foreign taxes.  The rules governing the  foreign  tax credit are complex.  You 
should  consult  your  tax  advisors  regarding  the  availability  of  the  foreign  tax  credit  under  your  particular 
circumstances. 

Taxation of Capital Gains 

For  United  States  federal  income  tax  purposes,  you  generally  will  recognize  taxable  gain  or  loss  on  any  sale, 
exchange  or  other  disposition  of  a  common  share  or  ADS  in  an  amount  equal  to  the  difference  between  the  U.S. 
dollar value of the amount realized for the common share or ADS and your adjusted tax basis in the common share 
or ADS, determined in U.S. dollars.  Such gain or loss will be capital gain or loss.  The capital gain or loss will be 
long-term capital gain or loss if at the time of sale, exchange or other disposition you have held our common shares 
or ADSs for more than one year.  Capital gains of individuals derived with respect to capital assets held for more 
than one year are eligible for reduced rates of taxation.  The deductibility of capital losses is subject to limitations.  
Any gain or loss recognized by you will generally be treated as United States source gain or loss.  Consequently, a 
U.S.  holder  may  not  be  able  to  use  the  foreign  tax  credit  arising  from  Brazilian  tax  imposed,  if  any,  on  the 
disposition of a common share or ADS unless such credit can be applied (subject to applicable limitations) against 
tax due on other income treated as derived from foreign sources. 

Passive Foreign Investment Company Rules 

Based upon our current and projected income, assets and activities, we do not expect the common shares or ADSs to 
be  considered  shares  of  a  PFIC  for  our  current  fiscal  year  or  for  future  fiscal  years.    However,  because  the 
determination  of  whether  the  common  shares  or  ADSs  constitute  shares  of  a  PFIC  will  be  based  upon  the 
composition of our income and assets, and entities in which we hold at least a 25% interest, from time to time, and 
because there are uncertainties in the application of the relevant rules, there can be no assurance that the common 
shares or ADSs will not be considered shares of a PFIC for any fiscal year.  If the common shares or ADSs were 
shares of a PFIC for any fiscal year, U.S. holders (including certain indirect U.S. holders) may be subject to adverse 
tax consequences, including the possible imposition of an interest charge on gains or “excess distributions” allocable 
to prior years in the U.S. holder’s holding period during which we were determined to be a PFIC.  If we are deemed 
to  be  a  PFIC  for  a  taxable  year,  dividends  on  our  ADSs  would  not  be  “qualified  dividend  income”  subject  to 
preferential rates of U.S. federal income taxation.  U.S. holders should consult their own tax advisors regarding the 
application of the PFIC rules to the common shares or ADSs. 

Information Reporting and Backup Withholding 

In general, information reporting requirements will apply to dividends in respect of our common shares or ADSs or 
the proceeds received on the sale, exchange, or redemption of our ADSs, in each case to the extent treated as being 
paid within the United States (and in certain cases, outside of the United States) to you unless you establish you are 
an  exempt  recipient  (such  as  a  corporation),  and  backup  withholding  may  apply  to  such  amounts  if  you  do  not 
establish you are an exempt recipient and you fail to provide a correct taxpayer identification number.  The amount 
of any backup withholding from a payment to you will be allowed as a refund or credit against your United States 
federal income tax liability provided you timely furnish the required information to the Internal Revenue Service.

maintained  by  the  Commission  and  the  New  York  Stock  Exchange,  you  may  obtain  a  copy  of  the  annual  report, 
upon  written  request  from  the  depositary  for  our  ADSs  at  its  corporate  trust  office  located  at  101  Barclay  Street,

We  also  furnish  to  the  depositary  annual  reports  in  English  including  audited  annual  financial  statements  and 
unaudited  quarterly financial  statements  in  English  for each of  the  first  three  quarters of  the  fiscal year.   We  also 
furnish to the depositary English translations or summaries of all notices of shareholders’ meetings and other reports 
and communications that are made generally available to holders of common shares.  

ITEM 11.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

We  are  exposed  to  various  market  risks—in  particular,  foreign  currency  exchange  rate  risk  and  interest  rate  risk.  
We  are  exposed  to  exchange  rate  risk  because  a  substantial  portion  of  our  financial  expenses  are  denominated  in 
foreign  currencies  (primarily  the  U.S.  dollar),  while  we  generate  all  of  our  net  operating  revenues  in  reais.  
Similarly,  we  are  subject  to  interest  rate  risk  based  upon  changes  in  interest  rates,  which  affect  our  net 
financial expenses.   

Exchange Rate Risk 

As of December 31, 2006 and 2005, approximately R$1,472.8 million and R$1,576.0 million, or 23.3% and 23.7%, 
respectively, of  our debt  obligations  were denominated  in  foreign  currencies (including debt  pegged  to  baskets  of 
foreign  currencies).    The  basket  of  foreign  currency-pegged  debt  consists  primarily  of  our  debt  with  the  Inter-
American  Development  Bank  and  the  World  Bank.    As  a  result,  we  are  exposed  to  exchange  rate  risks  that  may 
adversely  affect  our  financial  condition  and  results  of  operations,  as  well  as  our  ability  to  meet  debt  service 
obligations.  For example, we estimate that the potential loss to us in connection with U.S. dollar-denominated debt 
that would have resulted as of December 31, 2006 and 2005 from each hypothetical instantaneous and unfavorable 
1%  change  in  the  U.S.  dollar  against  the  real  would  have  been  approximately  (unaudited)  R$14.7  million  and 
R$15.8  million,  respectively.    Consistent  with  these  estimates,  a  hypothetical  instantaneous  and  unfavorable  10% 
change  in  this  exchange  rate  would  have  resulted  in  losses  of  approximately  (unaudited)  R$147.3  million  and 
R$157.6 million as of December 31, 2006 and 2005, respectively.  These estimates do not take into account that the 
changes in exchange rates comprising the baskets of  foreign currencies often present variations different  from the 
devaluation of the real in relation to the U.S. dollar. 

The devaluation of the real in relation to the U.S. dollar and with the Inter-American Development Bank and World 
Bank basket of currencies, for the year ended December 31, 2006 were as follows: 

Devaluation (appreciation) of real in relation to:

We have not utilized derivative financial instruments, although at times, we enter into forward exchange transactions 
and financial funding transactions in reais to mitigate foreign currency exposure. 

As of December 31, 2006 and 2005, we had no short-term debt outstanding, other than the current portion of long-
term debt. 

Interest Rate Risk 

As of December 31, 2006 and 2005, approximately R$2,598.8 million, or 53.3%, and R$2,726.7 million, or 53.6%, 
respectively,  of  our  total  debt  outstanding  balance  denominated  in  reais,  was  based  on  variable  rates  of  interest 
based  on  the  Unidade  Padrão  de  Referência—UPR  (Reference  Standard  Unit),  which  is  equal  to  the  Taxa 
Referencial—TR  (daily  government  interest  rate).    In  addition,  on  December  31,  2006  and  2005,  approximately 
R$1,041.4 million, or 21.5%, and R$1,116.4 million, or 21.9%, respectively, of our total debt denominated in reais 
was subject to interest rates based on the Certificado de Depósito Interbancário, or CDI, rate (benchmark interest 
rate set by the Brazilian interbank market on a daily basis).  As of December 31, 2006 and 2005, R$849.4 million 
and  R$901.8 million,  respectively,  of  our  foreign-currency  denominated  debt  was  based  on  the  Inter-American 
Development Bank and the World Bank variable rates of interest, which are determined based on the cost of funding 
of these multilateral organizations in each period. 

As of December 31, 2006 and 2005, we did not have any derivative contracts outstanding which limited exposure to 
changes  in  the  UPR  or  the  CDI  or  in  the  Inter-American  Development  Bank  or  World  Bank  variable  rates.  
However,  we  are  obliged  by  law  to  invest  our  excess  cash  with  financial  institutions  controlled  by  the  Brazilian 
government.    We  invest  these  excess  funds,  which  totaled  R$248.1  million  on  December  31,  2006  and 
R$155.7 million on  December  31, 2005,  mainly in short-term  instruments.   As a result,  our  exposure  to Brazilian 
interest  rate  risk  is  partially  limited  by  our  real-denominated  floating  interest  time  deposits  investments,  which 
generally  earn  the  CDI  rate.    In  addition  to  our  exposure  with  respect  to  existing  indebtedness,  we  may  become 
exposed to interest rate volatility with respect to indebtedness incurred in the future. 

We  estimate  that  we  would  have  suffered  a  loss  over  periods  of  one  year,  respectively,  of  up  to  R$10.5  million 
(unaudited)  and  R$11.2  million  if  a  hypothetical  instantaneous  and  unfavorable  change  of  100  basis  points  in  the 
interest  rates  applicable  to  financial  liabilities  on  December  31,2006  and  2005,  respectively,  had  occurred.  
Consistent with these estimates, a hypothetical instantaneous and unfavorable 10%, or 1000 basis point, change in 
these interest rates would have resulted in losses of approximately R$104.1 million (unaudited) and R$116.6 million 
as  of  December  31,  2006  and  2005,  respectively.    This  sensitivity  analysis  is  based  on  the  assumption  of  an 
unfavorable  100  basis  point  movement  of  the  interest  rates  applicable  to  each  homogeneous  category  of  financial 
liabilities  and  sustained  over  a  period  of  one  year  and  that  such  movement  may  or  may  not  affect  interest  rates 
applicable to any other homogenous category of financial liabilities.  A homogeneous category is defined according 
to the currency in which financial liabilities are denominated and assumes the same interest rate movement within 
each homogeneous category (e.g., U.S. dollars).  As a result, our interest rate risk sensitivity model may overstate 
the  effect  of  interest  rate  fluctuation  on  these  financial  instruments,  as  consistently  unfavorable  movements  of  all 
interest rates are unlikely. 

The tables below provide information about our interest rate-sensitive instruments.  For variable interest rate debt, 
the  rate  presented  is  the  weighted  average  rate  calculated  as  of  December  31,  2006.    For  the  foreign  currency 
denominated obligations these amounts have been converted at the selling rates as of December 31, 2006, and do not 
represent amounts which may actually be payable with respect to such obligations on the dates indicated.

Disclosure  Controls  and  Procedures.    We  maintain  disclosure  controls  and  procedures  (as  defined  in  the  U.S. 
Securities Exchange Act of 1934  under Rule 13a-15(e)) that are designed to ensure that information required to be 
disclosed by us in the reports that we file and submit under the Exchange Act is recorded, processed, summarized 
and  reported  within  the  time  periods  specified  in  Securities  and  Exchange  Commission  rules  and  forms,  and 
accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer 
and  Investor Relations Officer, to allow timely decisions  regarding required disclosures.   Our  management, under 
the  supervision  and  with  the  participation  of  our  Chief  Executive  Officer  and  our  Chief  Financial  Officer  and 
Investor Relations Officer, has evaluated the effectiveness of our disclosure controls and procedures as of December 
31,  2006,  the  end  of  the  period  covered  by  this  annual  report.    Based  on  this  evaluation,  which  included 
consideration  of  the  material  weaknesses  described  below  and  our  inability  to  file  this  annual  report  within  the 
statutory time period, our management, including our Chief Executive Officer and our Chief Financial Officer and 
Investor Relations Officer, has concluded that as of December 31, 2006, our disclosure controls and procedures were 
not effective.   

In  light  of the material weaknesses, we performed additional analysis and other post-closing procedures to ensure 
that  our  financial  statements  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in 
Brazil and in the United States.  Accordingly, we believe that the financial statements included in this annual report 
fairly  present,  in  all  material  respects,  our    financial  position,  results  of  operations  and  cash  flows  for  the  period 
presented. 

Management’s  Annual  Report  on  Internal  Control  over  Financial  Reporting.    Our  management  is  responsible  for 
establishing  and  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the 
effectiveness  of  internal  control  over  financial  reporting  as  defined  in  Rules  13a-15  (f)  under  the  U.S.  Securities 
Exchange Act of 1934. 

The Company’s internal control over financial reporting is a process designed by, or under the supervision of, the 
Company’s Chief Executive Officer and Chief Financial Officer and Investor Relations Officer, and effected by the 
Company’s board of directors, audit committee, management, and other personnel to provide reasonable assurance 
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in 
accordance with generally accepted accounting principles. The Company’s internal control over financial reporting 
includes  those  policies  and  procedures  that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable 
assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance 
with generally accepted accounting principles, and that receipts and expenditures of the Company are being made 
only in accordance with authorizations  of  management and directors of  the  Company; and  (3)  provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s 
assets that could have a material effect on the financial statements. 

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  material 
misstatements  on  a  timely  basis.   Therefore  even  those  systems  determined  to  be  effective  can  provide  only 
reasonable  assurance  with  respect  to  financial  statement  preparation  and  presentation.   Also,  projections  of  any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of 
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Our  management,  under  the  supervision  and  with  the  participation  of  our  Chief  Executive  Officer  and  Chief 
Financial  Officer  and  Investor  Relations  Officer,  assessed  the  effectiveness  of  our  internal  control  over  financial 
reporting  as  of  December  31,  2006,  based  on  the  criteria  established  in  Internal  Control  –  Integrated  Framework 
issued by the Committee of Sponsoring Organizations of the Treadway Commission – COSO.

A  material  weakness  is  a  control  deficiency,  or  a  combination  of  control  deficiencies,  that  results  in  more  than  a 
remote likelihood that a material misstatement of the financial statements will not be prevented or detected.  During 
our  management’s  assessment  of  the  Company’s  internal  control  over  financial  reporting  described  above,  our 
management  identified  the  following  material  weaknesses  in  internal  control  over  financial  reporting  as  of 
December 31, 2006: 

1.  Ineffective  controls  related  to  the  reconciliation  and  monitoring  of  the  balance  of  the  Unidentified 
Collections (Unapplied Cash Receipts) account, included as part of  Customer Accounts Receivable.  As a 
result of this control deficiency, the Company identified the need to adjust the balance of this account in the 
amount of R$93,758 thousand for the year ended December 31, 2006.   

2.  Ineffective  controls  to  ensure  the  timely  and  accurate  transfer  of  amounts  from  the  construction-in-
progress  account  to  the  corresponding  accounts  for  property,  plant  and  equipment,  as  well  as  the  timely 
commencement  of  recorded  depreciation  expense  associated  with  capital  assets  placed  in  service.   This 
control deficiency resulted in audit adjustments to the financial statements for the year ended December 31, 
2006.   

Because of the material weaknesses described above, management concluded that as of December 31, 2006, we did 
not maintain effective internal control over financial reporting based on the criteria established in “Internal Control – 
Integrated Framework” issued by COSO.   

Management’s  assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of 
December  31,  2006  has  been  audited  by  Deloitte  Touche  Tohmatsu  Auditores  Independentes,  the  Company’s 
independent registered public accounting firm, whose report is included herein. 

Changes  in internal  control over  financial reporting.  There have  been  improvements  in  our  internal control  over 
financial reporting as of December 31, 2006.  Our management adjusted the current controls and implemented other 
controls that reinforced our internal control structure and guaranteed a substantial improvement in the effectiveness 
of the financial statements such as the Code of Ethics, the Whistleblowing hotline, the updating of the Procedure for 
the  Establishment  of  Responsibilities,  the  restructuring  of  the  internal  auditing  body,  and  the  reviewing  of 
procedures through the introduction of a system for checking approvals. 

To  address  the  identified  material  weaknesses  noted  above,  subsequent  to  December  31,  2006,  we  have  begun  to 
implement a remediation program, including the establishment of additional controls intended to strengthen internal 
controls over financial reporting in general, and specifically to address the identified material weaknesses. 

Plans to Remediate the Material Weaknesses 

Specifically to address the material weaknesses described above, our management, under the supervision and with 
the participation of our Chief Executive Officer and Chief Financial Officer and Investor Relations Officer, has been 
actively engaged in the implementation of remediation efforts. 

Major initiatives include: 

1. 

to implement more stringent policies and procedures for our processes over accounting reconciliation; 

2. 

3. 

to  perform  an  extensive  study  and  a  reconciliation  of  the  balance  of  the  Unidentified  Collections 
(Unapplied Cash Receipts) account, included as part of Customer Accounts Receivable; 

to introduce a review by an independent department to ensure the timely and accurate transfer of amounts 
from the construction-in-progress account to the corresponding accounts for property, plant and equipment; 

4. 

to automate certain controls that are currently performed manually; 

118 

 
 
5. 

6. 

to  perform  a  month-end  review  and  closing  processes  as  well  as  to  provide  additional  oversight  and 
supervision within the accounting department; 

to  promote  programs  that  provide  ongoing  training  and  professional  education  as  well  as  development 
plans  for  the  accounting  department  and  to  improve  internal  communications  procedures  throughout  the 
company. 

The action plan described above has been submitted and approved by our audit committee.  

All of this work is being conducted by a group designed specifically to address the internal control issues related to 
the  reconciliation  of  the  balance  of  the  Unidentified  Collections  account  and  the  timely  and  accurate  transfer  of 
amounts from the construction-in-progress account to the corresponding accounts for property, plant and equipment. 

Our  management will  review  progress on these activities on a consistent and ongoing  basis  at the  chief executive 
officer level, across the senior management team.  An assessment report will be presented to our audit committee by 
the end of the third quarter of 2007.  Our management also plans to take additional steps to elevate our awareness 
and communications of these important issues through formal channels such as meetings and training. 

Our management believes that these actions will generally strengthen our disclosure controls and procedures, as well 
as  our  internal  control  over  financial  reporting,  and  will  address  the  material  weaknesses  that  we  identified  in  its 
internal control over financial reporting as of December 31, 2006.

REPORT  OF  INDEPENDENT  REGISTERED  PUBLIC  ACCOUNTING  FIRM  ON  INTERNAL 
CONTROL OVER FINANCIAL REPORTING 

To the Shareholders and Management of 
Companhia de Saneamento Básico do Estado de São Paulo - SABESP 

We have audited  management’s assessment, included in the accompanying Management's Report on Internal Control 
over  Financial  Reporting,  that  Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo  -  SABESP  (a  Brazilian 
Corporation  hereinafter  referred  to  as  the  “Company”)  did  not  maintain  effective  internal  control  over  financial 
reporting as of December 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by 
the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  The  Company’s  management  is 
responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness 
of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and 
an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United 
States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether 
effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining 
an  understanding  of  internal  control  over  financial  reporting,  evaluating  management’s  assessment,  testing  and 
evaluating  the  design  and  operating  effectiveness  of  internal  control,  and  performing  such  other  procedures  as  we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions. 

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  by,  or  under  the  supervision  of,  the 
company’s principal executive and principal financial officers, or persons performing similar functions, and effected by 
the  company’s  board  of  directors,  management,  and  other  personnel  to  provide  reasonable  assurance  regarding  the 
reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with 
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions  and  dispositions  of  the  assets  of  the  company;  (2)  provide  reasonable  assurance  that  transactions  are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely 
detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on 
the financial statements. 

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or 
improper  management  override  of  controls,  material  misstatements  due  to  error  or  fraud  may  not  be  prevented  or 
detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial 
reporting  to  future  periods  are  subject  to  the  risk  that  the  controls  may  become  inadequate  because  of  changes  in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

A material weakness is a significant deficiency, or combination of significant deficiencies, that results in more than a 
remote  likelihood  that  a  material  misstatement  of  the  annual  or  interim  financial  statements  will  not  be  prevented  or 
detected. The following material weaknesses have been identified and included in management's assessment: 

Ineffective controls related to the reconciliation and monitoring of the balance of the Unidentified Collections 
(Unapplied Cash Receipts) account, included as part of  Customer Accounts Receivable.  As a result of this 
control  deficiency,  the  Company  identified  the  need  to  adjust  the  balance  of  this  account  in  the  amount  of 
R$93,758 thousand for the year ended December 31, 2006; and    

Ineffective  controls  to  ensure  the  timely  and  accurate  transfer  of  amounts  from  the  construction-in-progress 
account to the corresponding accounts for property, plant and equipment, as well the timely commencement of 
recorded depreciation expense associated with capital assets placed in service. This control deficiency resulted 
in audit adjustments to the annual financial statements for the year ended December 31, 2006. 

These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our 
audit  of  the  balance  sheet  as  of  December  31,  2006,  and  the  related  statements  of  income,  shareholders’  equity  and 
changes in financial position as of and for the year ended December 31, 2006 of the Company, and this report does not 
affect our report on such financial statements. 

F-3 

 
 
 
In our opinion,  management's assessment that the Company did not  maintain effective internal control over  financial 
reporting as of December 31, 2006 is fairly stated, in all material respects, based on the criteria established in Internal 
Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. 
Also  in  our  opinion,  because  of  the  effect  of  the  material  weaknesses  described  above  on  the  achievement  of  the 
objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as 
of  December  31,  2006,  based  on  the  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the 
Committee of Sponsoring Organizations of the Treadway Commission (COSO). 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the financial statements as of and for the year ended December 31, 2006 of the Company and our report dated 
June  29,  2007  expressed  an  unqualified  opinion  on  those  financial  statements,  containing  explanatory  paragraphs 
concerning (1) the Company’s negotiations with the State of São Paulo Government regarding the reimbursement of the 
amounts for supplementary retirement and pension paid by the Company and the future flow of these payments to be 
reimbursed by the State of São Paulo Government; (2) how the Company´s application of accounting practices adopted 
in Brazil vary in certain respects from accounting principles generally accepted in the United States of America; (3) the 
Company’s restatement of restatement of its presentation of cash and cash equivalents as prepared in accordance with 
U.S.  GAAP  for  the  years  ended  December  31,  2005  and  2004;  and  (4)  the  Company’s  adoption  of  Statement  of 
Financial  Accounting  Standards  No.  158,  “Employers’  Accounting  for  Defined  Benefit  Pension  and  Other 
Postretirement Plans – an amendment of FASB Statements No. 87, 88, 106 and 132(R) effective December 31, 2006.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

To the Shareholders and Management of 
Companhia de Saneamento Básico do Estado de São Paulo - SABESP 

We  have  audited  the  accompanying  balance  sheets  of  Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo  - 
SABESP (a Brazilian Corporation hereinafter referred to as the “Company”) as of December 31, 2006 and 2005, and 
the related statements of income, changes in shareholders’ equity and changes in financial position for each of the three 
years  in  the  period  ended  December  31,  2006.  These  financial  statements  are  the  responsibility  of  the  Company’s 
management. Our responsibility is to express an opinion on these financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the 
financial  statements  are  free  of  material  misstatement.  An  audit  also  includes  examining,  on  a  test  basis,  evidence 
supporting  the  amounts  and  disclosures  in  the  financial  statements,  assessing  the  accounting  principles  used  and 
significant  estimates  made  by  management,  as  well  as  evaluating  the  overall  financial  statements  presentation.  We 
believe that our audits provide a reasonable basis for our opinion. 

In our opinion, such financial statements present fairly, in all material respects, the financial position of Companhia de 
Saneamento  Básico  do  Estado  de  São  Paulo  -  SABESP  as  of  December  31,  2006  and  2005,  and  the  results  of  its 
operations, changes in shareholders’ equity and changes in its financial position for each of the three years in the period 
ended December 31, 2006, in conformity with accounting practices adopted in Brazil. 

Accounting  practices  adopted  in  Brazil  vary  in  certain  respects  from  accounting  principles  generally  accepted  in  the 
United States of America. The application of the latter would have affected results of operations for each of the three 
years in the period ended December 31, 2006 and the determination of shareholders’ equity as of December 31, 2006 
and 2005, to the extent summarized in Note 23 to the financial statements. 

Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The 
statements of cash flows for each of the three years in the period ended December 31, 2006 are presented for purposes 
of additional analysis and is not a required part of the basic consolidated financial statements prepared in accordance 
with accounting practices adopted in Brazil. Such information has been subjected to the auditing procedures applied in 
the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the 
basic financial statements taken as a whole. 

As mentioned in Note 6, the Company is negotiating with the State of São Paulo Government the reimbursement of the 
amounts for supplementary retirement and pension paid by the Company and the future flow of these payments to be 
reimbursed by the State of São Paulo Government.  

As  discussed  in  Note  28,  the  Company  has  restated  its  presentation  of  cash  and  cash  equivalents  as  prepared  in 
accordance with U.S. GAAP for the years ended December 31, 2005 and 2004. 

As mentioned in Note 23(i), the Company adopted the provisions of Statement of Financial Accounting Standards No. 
158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans – an amendment of FASB 
Statements No. 87, 88, 106 and 132(R) effective December 31, 2006.   

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006, based on 
the  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission  (COSO)  and  our  report,  dated  June  29,  2007,  expressed  an  unqualified 
opinion  on  management’s  assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting 
and  an  adverse  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  because  of 
material weaknesses.

OPERATIONS 

Companhia de Saneamento Básico do Estado de São Paulo - SABESP (the “Company”) is engaged in the 
operation  of  public  water  and  sewage  systems  in  the  State  of  São  Paulo,  Brazil,  providing  water  and 
sewage  services  to  a  broad  range  of  residential,  commercial,  industrial  and  government  customers.  The 
Company also provides water on a wholesale basis to certain municipalities in the São Paulo Metropolitan 
Region that do not have water production systems.  

With the enactment of Law 12,292 on March 2, 2006 we became authorized to provide water and sewage 
services outside the State of São Paulo, including in other countries, either directly or through national or 
international consortia. We may also have equity participation in other state or mixed-capital companies, 
and establish subsidiaries. 

The Company’s shares are listed on the São Paulo Stock Exchange (“BOVESPA”) in the “New Market” 
segment  since  April,  2002,  and  on  the  New  York  Stock  Exchange  -  NYSE,  in  the  form  of  ADRs 
(American Depositary Receipts) since May, 2002. 

The Company provides water and sewage services in 367 municipalities in the State of São Paulo, nearly 
all of which are through concessions granted by the municipalities, most of them initially contracted for a 
30-years term. The 120 (one hundred twenty) concession contracts that expired until December 31, 2006 
are  in  process  of  negotiation.  In  2007,  53  (fifty  three)  contracts  are  going  to  expire,  150  (one  hundred 
fifty) contracts between 2008 and 2034 and the remaining without determined term. Management expects 
that  the  referred  concessions  will  be  renewed  or  extended,  thus  there  will  not  be  a  discontinuity  of  the 
water supply and sewage collection. The net book value of property, plant and equipment items relating to 
the  municipalities  where  the  concessions  are  under  negotiation  or  will  expire  in  2007  totals  R$  1.94 
billion,  and  the  net  revenue  for  the  year  ended  December  31,  2006  totals  R$  796  million  in  relation  to 
these concessions. 

The Company does not hold a formal concession to provide water and sewage services in the City of São 
Paulo, which accounts for 56,8% of the sales and services rendered. In Santos, a municipality located in 
the Santos Coastal Area, which also has a significant population, the Company operates under a public 
deed  of  authorization,  like  in  some  other  municipalities  in  the  Santos  Coastal  Area  and  in  the  Ribeira 
Valley, where the Company started operating after the merger of companies that formed SABESP.  

On January 5, 2007 Law 11,445 was enacted establishing the regulatory framework of basic sanitation, 
with  the  national  guidelines  and  the  fundamental  principles  to  the  rendering  of  services,  like  the  social 
control,  the  transparency, the  command  integration  of  the  sanitation  infrastructures,  the  management  of 
hydric resources, as well as the command for the articulation of the industry with the public policies of 
urban  and  regional  development,  housing,  combat  and  irradication  of  poverty,  promotion  of  health  and 
environmental  protection,  among  other  related  ones.  The  regulatory  framework  seeks  also  the 
improvement  of  life  quality  with  efficiency  and  the  economic  sustainability,  allowing  the  adoption  of 
gradual and progressive solutions coherent to the user’s payment capacity. 

As benefits to the Company, the law:

need of the Municipalities to present sanitation plans, compatible with the plans of the hydrographic 
basins; and 
Imposes  the  indication  of  the  regulating  entity  and  the  publishing  of  regulatory  rules  that  allow 
more  clarity  and  efficiency  in  the  inspection  of  services,  as  well  as  the  providing  itself, 
safeguarding and compatibilizing the different interests of the customer and the contracting parties. 

In general, the Company does not face  any  competition in the municipalities in which it  provides water 
and sewage services, and management believes that in those municipalities the Company has an exclusive 
right to provide such services. 

All  information  about  the  concession  area,  number  of  municipalities,  volume  of  water  and  sewage  and 
other related data disclosed in this report that do not arise from the accounting and/or financial statements 
are not examined by the independent auditors.

PRESENTATION OF THE FINANCIAL STATEMENTS 

The Company’s statutory financial statements, which are used as the basis for determining income taxes 
and  mandatory  minimum  dividend  calculations,  have  been  prepared  in  accordance  with  accounting 
practices  adopted  in  Brazil,  which  are  based  on  the  Brazilian  Corporate  Law  (Law  No.  6,404/76,  as 
amended), the rules and regulations of the Brazilian Securities Commission ("CVM") and the accounting 
standards issued by the Brazilian Institute of Independent Auditors (“IBRACON”), collectively referred 
to  hereinafter  as  “Corporate  Law”  or  “BR  CL”.  The  financial  statements  prepared  in  accordance  with 
Corporate Law have not been indexed for inflation after 1995. 

(a) 

Inflation accounting under BR CL 

BR CL provided a simplified methodology for accounting for the effects of inflation through 1995. This 
method consisted of restating permanent assets (property, plant and equipment, investments and deferred 
charges) and shareholders’ equity accounts using indices mandated by the Brazilian Federal Government. 
The net effect of these restatements was credited or charged to the statement of income. 

(b) 

Presentation of financial statements 

To  facilitate  an  understanding  of  Brazilian  accounting  practices,  the  presentation  of  the  financial 
statements  has  been  adapted  from  the  financial  statements  filed  for  Brazilian  legal  and  regulatory 
purposes.  In  addition,  certain  terminology  changes  have  been  made  and  the  notes  to  the  financial 
statements  have  been  expanded  to  conform  them  more  closely  to  reporting  practices  prevailing  in  the 
United  States  of  America.  All  amounts  are  presented  in  Brazilian  currency  (“real”  or  “reais”),  unless 
otherwise indicated.

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

These  financial  statements  include  the  modifications  introduced  by  the  following  accounting  normative 
rules:  (i)  Accounting  Rules  and  Procedures  27  (NPC  27  -  Presentation  and  Disclosure),  issued  by  the 
Brazilian  Institute  of  Accountants  -  Ibracon,  on  October  3,  2005,  approved  by  the  CVM  Resolution  n. 
488, on the same date, and (ii) NPC 22 - Provisions, Liabilities, Contingent Liabilities and Assets, issued 
by  Ibracon,  on  October  3,  2005,  approved  by  the  CVM  Resolution  n.  489,  on  the  same  date.  In  the 
financial statements refering to the year ended December 31, 2005, presented for comparative purposes, 
some  reclassifications  have  been  made  in  order  to  conform  them  to  the  mentioned  resolutions,  and  to 
allow users the comparability to the current period. The main changes resulting from the application of 
these resolutions were the following: 

• 
• 
• 

Presentation of the group “Non-Current” in assets and liabilities, 
Presentation of the account “Intangible” classified in the group “Non current assets”, and 
Reclassification of escrow deposits, previously classified in assets, to liabilities, as a reduction of 
the account “provision for contingencies”, where applicable. 

The financial statements for the year ended December 31, 2005 were reclassified for better presentation 
and  comparability  maintenance,  as  well  as  the  respective  impact  to  the  Statement  of  Changes  in 
Financial Position, cash flow and value added statement, when applicable, as described below: 

-  Previoulsy classified as escrow deposits as non-current assets, the amount of R$ 4,069 was classified 
as  a  reduction  of  the  provisions  for  contingencies  in  current  liabilities  and  provision  for 
contingencies in non-current liabilities, in the amounts of R$ 3,037 and R$ 1,032, respectively. 
-  Previously classified as accounts receivable from private customers, the amount of R$ 126,151 was 

reclassified to the account transactions with related parties. 

-  Refundable amounts previously classified as other liabilities, in non-current liabilities, in the amount 

of R$ 73,829 were reclassified to the account other current liabilities as current liabilities. 

-  Taxes  recoverable  in  the  amount  of  R$ 853,  previously  classified  in  other  accounts  receivable  in 

current assets, were reclassified to the account taxes recoverable in current assets. 

-  Services received, previously classified as other current liabilities in current liabilities, in the amount 

of R$ 107,660, were reclassified to the account services received in current liabilities. 

-  Previously  classified  as  costs  of  sales  and  services  provided,  the  amount  of  R$ 14,046  was 

reclassified to administrative expenses. 

-  Previously  classified  as  selling  expenses,  the  amount  of  R$ 32  was  reclassified  to  administrative 

expenses.

SIGNIFICANT ACCOUNTING PRACTICES 

The  Company’s  accounting  practices,  which  are  based  on  the  accrual  concept,  comply  with  the 
Corporate Law but differ in certain significant respects from accounting principles generally accepted in 
the  United  States  of  America  (“US  GAAP”).  See  Note  23  for  further  discussion  of  the  differences 
between BR CL and US GAAP and the reconciliation of shareholders’ equity and net income between 
BR CL and US GAAP. Additional disclosure has been included in the notes to the financial statements 
to comply with the regulations of the U.S. Securities and Exchange Commission (the “SEC”) for foreign 
registrants. 

(a) 

Revenues from sales and services  

Revenues  from  water  and  sewage  services  are  recognized  as  water  is  consumed  or  as  services  are 
provided.  Revenues  from  water  and  sewer  services  rendered,  but  not  billed,  are  recorded  as  unbilled

customer  accounts  receivable  based  on  monthly  estimates,  in  order  to  match  such  revenue  with  costs 
incurred.  

In the fiscal year ended December 31, 2004, revenue was recorded net of customer discounts relating to 
the Program for Consumption Reduction Incentive Program (see Note 19). 

(b) 

Marketing costs 

Marketing  costs  are  generally  recorded  in  administrative  expenses.  Marketing  costs  were  R$ 11,895, 
R$ 17,861  and  R$31,615  for  the  years  ended  on  December  31,  2006,  2005  and  2004,  respectively.  No 
marketing costs were deferred at December 31, 2006, 2005 and 2004.  

(c) 

Financial income and expenses 

Financial income and expense are primarily comprised of interest, monetary and exchange variations on 
loans and financing, contingencies, accounts receivable and financial investments, and are calculated and 
reported on the accrual basis of accounting. 

(d) 

Income tax and social contribution 

Income and social contribution taxes (a federally mandated tax based on income) are accrued on taxable 
results. 

Income tax is calculated at the rate of 15%, plus a 10% surtax, and social contribution at the rate of 9%. 
Those rates are reported on an accrual basis. 

Deferred taxes are calculated based on taxable or dedutible amounts in future years and are recognized to 
the extent that realization is believed to be probable. 

As  permitted  by  the  “CVM”,  the  Company  opted  not  to  recognize  the  deferred  income  and  social 
contribution taxes on the revaluation reserve of property, plant and equipment recorded up to 1991. 

(e) 

Other income and expenses  

Other income and expenses are recorded on an accrual basis. 

(f) 

Cash and cash equivalents 

Cash and cash equivalents comprise primarily bank deposits and financial investments and are carried at 
cost plus accrued interest, if applicable. Financial investments denominated in Reais have a ready market, 
and are  mostly  represented  by Bank Deposit Certificates -  CDB’s in 2006 and by Financial Investment 
Funds - “FIF’s” in 2005 and 2004. The Company is required by law to invest excess cash with financial 
institutions controlled by the State Government (see note 6).  

(g) 

Customer accounts receivable and allowance for doubtful accounts 

Customer accounts receivable generally do not accrue interest or indexation charges or penalties, except 
for refinanced agreements.

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

The Company records an allowance for doubtful accounts for receivable balances in an amount that is 
deemed  by  management  to  be  sufficient  to  cover  probable  losses  in  accounts  receivable,  based  on  an 
aging analysis of receipts, taking into consideration the expected recovery in the different categories of 
customers accounts.  Amounts in excess of R$ 5 and overdue for more than 360 days and in excess of 
R$  30  and  overdue  for  more  than  360  days,  which  are  under  judicial  collection  proceedings,  are 
provisioned. Accounts receivable balances under R$ 5 and overdue more than 180 days are written off 
through a direct charge to income. 

The  Company does not record allowance for  doubtful accounts for any  amounts due to it by the State 
Government or entities controlled by the State Government, since it does not expect to incur in losses 
from such balances. 

(h) 

Inventories 

Inventories of materials used in operations and in the maintenance of the Company’s water and sewage 
systems  are  stated  at  lower  of  average  acquisition  cost  or  realizable  value  and  are  classified  in  current 
assets. Inventories for capital projects are classified under property, plant and equipment and are stated at 
the average acquisition cost. 

(i) 

Other current assets and long-term receivables 

Other  current  assets  and  long-term  receivables  are  stated  at  the  lower  of  acquisition  cost  or  realization 
value, plus accrued interest, when applicable. 

(j) 

Property, plant & equipment 

Property,  plant  and  equipment  are  generally  stated  at  amounts  established  by  independent  technical 
appraisals,  plus  price-level  restatements  from  the  date  of  the  appraisals  to  1995.  Revaluation  increments 
arising  from  revaluing  assets  to  appraised  values  are  recorded  in  the  revaluation  reserve  component  of 
shareholders' equity and subsequently transferred from the reserve to retained earnings as the related assets 
are  depreciated,  sold  or  upon  disposal.  The  price-level  restatement  adjustments  were  based  on  official 
inflation indices published by the federal government. The Company believes that the distortion caused by 
indices  which  understated  the  independently  measured  inflation  rate  have  been  mitigated  by  recording 
revaluation increments. 

The  revaluation  of  property,  plant  and  equipment  items,  carried  out  in  two  separate  stages  in  1990  and 
1991,  was  based  on  an  appraisal  report  issued  by  independent  experts.  The  referred  revaluation  was 
recorded with a corresponding credit to the “Revaluation Reserve” account in Shareholder’s Equity, and is 
realized  through  depreciation,  sale,  and  disposal  of  the  respective  assets,  with  a  corresponding  entry  to 
“Retained Earnings”. 

Contributions  of  property,  plant  and  equipment  by  third  parties  and  from  government  entities  (such  as 
property  owners)  to  allow  the  Company  to  supply  water  and  sewage  services  are  recorded  as  a  capital 
reserve.  

Construction-in-progress is recorded at cost and is primarily related to construction projects under contract 
with  third  parties.  For  long-term  projects,  the  Company  capitalizes  these  projects  once  the  Company’s 
engineering department approves that the project milestones have been achieved and the Company takes 
delivery of the assets.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Depreciation  

Depreciation  of  property,  plant  and  equipment,  is  recorded  using  the  straight-line  method  based  on  the 
estimated useful lives of the underlying assets. The principal depreciation rates are detailed in Note 8.  

Capitalization of interest 

Consistent  with  the  requirements  of  accounting  regulations  for  Brazilian  utility  companies,  up  to  1985, 
interest was capitalized at 12% per annum on construction-in-progress. Interest capitalized which exceeded 
interest  expense  on  loans  obtained  to  finance  construction-in-progress  was  recorded  in  a  capital  reserve 
directly  in  shareholders'  equity.  Up  to  1995,  BR  CL  did  not  require  the  capitalization  of  interest  costs 
incurred  during  the  construction  period  as  part  of  the  cost  of  the  related  property,  plant  and  equipment. 
However, as permitted by the Brazilian Water and Sewage Plan (Plano Nacional de Saneamento Básico - 
PLANASA), the Company capitalized interest on construction in progress through 1988. No interest was 
capitalized from 1989 to 1995.  Interest was again capitalized beginning in 1996, following changes in the 
CVM requirements in 1996.   Beginning in 1999, the Company has capitalized indexation charges on the 
real  -  denominated  loans  and  financing  and  the  foreign  exchange  effects  on  foreign  currency  loans  and 
financing. The Company capitalizes interest incurred on borrowings to the extent that borrowings do not 
exceed construction-in-progress, which is recorded as a reduction of interest expense.  

Interest  capitalized  is  depreciated  with  the  cost  of  the  asset,  once  the  related  asset  becomes  operational. 
Through  December  31,  1998,  but not  thereafter,  such depreciation  of  capitalized  interest  was  deductible 
for purposes of determining taxes on income.  

Repairs and maintenance  

Improvements  to  existing  property  are  capitalized,  while  costs  of  general  maintenance  and  repairs  are 
expensed as incurred. Materials allocated to specific projects are added to construction-in-progress. 

Impairment 

The  Company  reviews  long-lived  assets,  primarily  buildings  and  water  and  sewage  systems,  including 
property, plant and equipment and concession assets,  to be held and used in the business, for the purpose 
of determining and measuring impairment on a recurring basis or when events or changes in circumstances 
indicate  that  the  carrying  value  of  an  asset  or  group  of  assets  may  not  be  recoverable.  The  Company 
assesses  impairment  on  the  basis  of  the  projected  recovery  of  depreciation  charges  through  results  of 
operations. The carrying value of assets or groups of assets is written down to realizable value if and when 
appropriate. 

(k) 

Concessions 

Beginning in 1999, acquisitions of concession assets and concession rights from third parties have been 
accounted for at fair values, as determined in technical appraisal reports. Accordingly, the purchase price, 
plus  direct  costs  of  acquisition,  is  allocated  to  assets  acquired  and  liabilities  assumed  based  upon  their 
estimated  fair  values  at  the  date  of  acquisition.  These  concessions  are  recorded  as  concession  assets 
acquired, included as intangible assets in the balance sheets.

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Concession rights are amortized on a straight-line basis over the estimated future periods to be benefited, 
not to exceed the contractual term of the concession. The straight-line method of depreciation is modified, 
when  applicable,  to  avoid  the  backloading  of  charges  in  later  years  by  estimating  future  disbursement 
commitments to meet the Company’s concession obligations.  

(l) 

Deferred Assets 

Deferred charges are comprised primarily of deferred project costs and technical studies, wich are being 
amortized using the straight-line method over 5 years from the date when benefits start to be generated. 

(m) 

Loans and Financing 

Loans  and  financing  are  adjusted  by  indexation  charges  and  foreign  exchange  variations  and  include 
accruals  for  related  interest  expenses  up  to  closing  date.  Loans  and  financing  denominated  in  foreign 
currencies are translated to reais using the exchange rate in effect at the balance sheet date. The resulting 
foreign currency exchange adjustments are recognized as incurred in financial income (expense), net. 

(n) 

Salaries and payroll charges 

Salaries and other payroll charges, including provisions for vacation pay, 13th salary and complementary 
payments  agreed  upon  through  collective  bargaining  agreements,  added  by  the  corresponding  payroll 
charges, are recorded on an accrual basis. 

(o) 

Provision for Contingencies 

Provisions  for  contingencies  are  recorded  at  the  estimated  amounts  to  cover  potential  losses  related  to 
labor,  tax,  civil,  commercial,  environmental  and  other  claims  and  lawsuits,  at  administrative  and  court 
levels, when such losses are considered probable by the Company’s legal advisors and are estimateable by 
management. 

Provisions for contingencies balances are being disclosed net of the related escrow deposits for 2006 and 
2005. 

(p) 

Environmental costs 

Costs  relating  to  ongoing  environmental  programs  are  expensed,  as  incurred.  Ongoing  programs  are 
designed  to  minimize  the  environmental  impact  of  operations  and  to  manage  the  environmental  risks 
inherent to the Company’s activities. Provisions for contingent losses related to environmental claims are 
recorded when they are considered to be probable and reasonably estimated by Management.  

(q) 

Pension obligation 

The  Company  sponsors  a  private  defined  benefit  pension  plan,  which  is  operated  and  administered  by 
Fundação SABESP de Seguridade Social (“SABESPREV”). CVM resolution 371 of December 13, 2000 
determines the recognition of actuarial liabilities exceeding to the plan assets. As permitted, the Company 
has elected to recognize the transition obligation as of the date of adoption in earnings on a straight-line 
basis over five years beginning January 1, 2002.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Brazilian corporations are permitted to deduct for tax purposes interest on shareholders’ equity, which is a 
distribution  similar  to  a  dividend.  For  financial  reporting  purposes,  interest  on  shareholders’  equity  is 
recorded as a deduction directly from unappropriated retained earnings. This interest has been recorded in 
accordance with Law 9249/95, for tax deductibility purposes, limited to the daily pro-rata variation of the 
Long-Term  Interest  Rate  (“TJLP”).  Withholding  taxes  with  respect  to  the  payment  of  interest  on 
shareholders’ equity is generally withheld and paid by the Company on behalf of shareholders (see note 
16). 

(s) 

Use of estimates 

The  preparation  of  financial  statements  requires  management  to  make  estimates  based  on  certain 
assumptions that affect the reported amounts of assets and liabilities and the reported amounts or revenues 
and expenses for the reporting periods. Actual results could differ from those estimates. 

(t) Earnings per share 

Earnings  per  share  is  calculated  based  on  the  number  of  shares  outstanding  at  the  balance  sheet 
date.

A  number  of  wholesale  customers  have  been  contesting  certain  tariffs  since  mid-1998.  As  a  result, 
some  municipalities  are  currently  not  paying  the  Company’s  invoices  in  full or  on  a  timely  basis.  In 
addition, some governmental entities located in municipalities the Company serves are also not paying 
on  a  regular  basis.  While  the  Company  continues  to  enter  into  negotiations  with  municipalities  to 
reschedule the related accounts receivable and continues to file legal proceedings against municipalities 
to  collect  overdue  amounts,  in  some  cases,  the  Brazilian  courts  have  required  that  the  Company 
continue to provide water on a wholesale basis to municipalities, even if they fail to pay the Company’s 
invoices. 

The Company recorded direct charges for probable losses in accounts receivable incurred in 2006, in the 
amount  of  R$  411,918,  being  R$ 115,739  (net  of  recoveries)  written-off  from  accounts  receivable  (in

2005  -  R$ 94,196),  directly  to  the  income  for  the  year,  recorded  in  “Selling  Expenses”.  These  losses 
amounted to R$ 255,292 and R$ 241,577 in 2005 and in 2004, respectively. 

Management believes that the allowance for doubtful accounts is sufficient to absorb probable losses in 
customer accounts receivable. 

(d) 

Unbilled amounts 

Unbilled amounts represent water and sewage services provided but not yet billed, which are estimated 
from the last measurement date to month-end based on prior month’s billings. 

(e) 

Unidentified collections 

In the process of analyzing and reconciliating the accounting balances related to the account “unidentified 
collections,” which belongs to the accounts receivable group, the Company identified the need to adjust 
the balance of this account in the amount of R$93,758.  This amount results from differences accumulated 
in  the  course  of  the  years.    The  adjustment  was  made  in  the  statement  of  income  for  the  year  ended 
December  31,  2006  due  to  the  impossibility  to  identify  the  period  of  the  amounts  that  caused  the 
accumulated differences.

The  Company  does  not  record  an  allowance  for  doubtful  accounts  for  any  amounts  due  from  the  State 
government  or  entities  controlled  by  the  State  Government,  since  it  does  not  expect  losses  on  such 
receivables. 

(i) 

Water and sewage services 

The Company provides water and sewage services to the State Government and its related agencies under 
terms  and  conditions  that  management  believes  are  equal  to  those  with  third  parties,  except  for  the 
settlement of amounts outstanding, as described further below in items (iii) and (iv). 

(ii) 

Reimbursement for pension and benefits paid. 

Reimbursement for pension and benefits paid represents supplementary pension and leave benefit paid by 
the  Company  to  former  employees  of  State  Government-owned  companies  which  merged  to  form 
SABESP. These amounts should be reimbursed to the Company by the State Government, as the primary 
obligor, in conformity with Law No. 200/74. At December 31, 2006 and 2005, 2,670 and 2,761 retirees, 
respectively, received supplementary pension payments, for which the Company paid R$ 101,740 and R$ 
96,388 at December 31, 2006 and 2005, respectively. There were 163 active employees at December 31, 
2006,  who  will  be  entitled  to  such  benefits  at  the  time  of  their  retirement,  as  compared  to  189  at 
December 31, 2005. 

(iii)   GESP Agreement 

On December 11, 2001, the Company entered into an agreement with the State of São Paulo Government, 
through  the  State  Department  of  Finance  and  the  State  Department  of  Water  and  Energy  -  “DAEE”, 
having the State Department of Water Resources, Sanitation and Works as intervening party, under which 
the State Government, by force of Law no 200/74, acknowledged to be responsible for the benefit arising 
out  of  supplementation  of  retirement  and  pension  payments  and  agreed  to  pay  amounts  it  owed  to  the 
Company in respect of water and sewage services. The value to date of the Agreement was R$ 678,830, 
of  which  R$ 320,623  refer  to  supplemental  retirement  and  pension  benefits  in  the  period  from  March 
1986 until November 2001, and R$ 358,207 refer to water supply and sewage collection services invoiced 
and due from 1985 until December 1, 2001.  The agreement foresees the equalizing of the balance of our 
accounts receivable with the use of dividends, when applicable. 

Considering  the  strategic  importance  of  Taiacupeba,  Jundiaí,  Biritiba,  Paraitinga  and  Ponte  Nova 
reservoirs, for ensuring the volume of water of the Alto Tietê System to be maintained, it was agreed that 
DAEE would transfer these properties to the Company, with the fair value of these transferred assets used 
to reduce the amounts owed to the Company.  

Under the December 2001 agreement, in July and August 2002, a State Government –owned construction 
company (Companhia Paulista de Obras e Serviços—CPOS), on behalf of the State, and an independent 
appraisal  firm  (ENGEVAL—Engenharia  de  Avaliações),  on  the  Company’s  behalf,  presented  their 
valuation  reports  relating  to  the  reservoirs.  Under  the  agreement,  the  arithmetic  average  of  these 
appraisals is deemed the fair value of the reservoirs. The appraisals contained in these reports were in the 
amounts of R$ 335.8 million and R$ 341.2 million, respectively. Because the Company had already made 
investments  in  these  reservoirs  by  then,  the  arithmetic  average  of  the  appraisals  submitted  to  the

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Company’s Board of Directors for approval in August 2002 of R$ 300.9 million was net of a percentage 
corresponding to these investments. Our Board of Directors approved the valuation reports. 

Under the December 2001 agreement, for amounts due in excess  of the fair value of the reservoirs, the 
State Government is to make payments in 114 consecutive monthly installments, with the first payment to 
be made upon the latest of (1) 210 days after the date of the agreement, (2) agreement by the parties on 
the  fair  value  of  the  reservoirs  and  (3) conclusion  of  the  audit by  a  State-appointed  auditor  of  amounts 
owed.  The  nominal  amount  owed  by  the  State  Government  would  not  be  indexed  to  inflation  or  earn 
interest if there was a delay in concluding the appraisal of fair value. The installments will be indexed on 
a monthly basis by the IGP-M, plus 6.0% per year, starting on the date the first installment becomes due. 
The original first payment was to be made in July 2002. 

On October 29, 2003, the Public Attorney of the State (Ministério Público do Estado de São Paulo), on 
behalf of the people of the State, brought a civil public action in a Trial Court of the state of São Paulo 
(12a  Vara  da  Fazenda  Pública  do  Estado  de  São  Paulo)  alleging  that  a  transfer  to  the  Company  of 
ownership  of  the  Alto  Tietê  System  reservoirs  from  DAEE  would  be  illegal.  An  injunction  against  the 
transfer of ownership of such reservoirs was granted but was later reversed. However, in October 2004, 
the court ruled in favor of the Public Attorney of the State, which the Company believes relates only to 
the illegality of the transfer of the reservoirs. In response, the Company filed an appeal which is pending 
final  decision  and  the  State  Government  successfully  filed  an  action  suspending  the  lower  Court’s 
decision until final judgment is reached by the Court of Appeals of the state of São Paulo (Tribunal de 
Justiça do Estado de São Paulo). The Company is unable to predict whether it will succeed in appealing 
such decision. Management currently does not expect that an eventual unfavorable decision would have 
material adverse effect on the Company’s business and financial condition. 

The December 2001 agreement also provided that the legal advisors of the State Government would carry 
out  specific  analyses,  which  have  commenced,  to  ensure  agreement  among  the  parties  as  to  the 
methodology employed in determining the amount of reimbursement for pension benefits owed to us by 
the  State  Government.  Management  does  not  expect  these  analyses  to  differ  significantly  from  the 
amounts recorded in respect of these amounts. The commencement of payments with respect to pension 
amounts  owed  by  the  State  Government  has  been  postponed  until  such  analyses  are  completed,  the 
appraisal report is approved and the credit assignments relating to the transfer of the reservoirs described 
above are formalized. In addition, the transfer of these reservoirs is currently being disputed and we are 
not certain whether such transfer will be legally allowed, as discussed above.  

Based on Official Notice No. 53/2005 of the State Capital Defense Council (CODEC), dated March 21, 
2005,  negotiations  are  still  ongoing  between  the  Company  and  the  State  Government  with  a  view  to 
restatement of the debt for supplemental retirement and pension benefits, under the terms defined in the 
December  2001  agreement,  including  amounts  due  after  November  2001.  These  negotiations  are 
expected to be consolidated in a second amendment to the December 2001 agreement, including criteria 
for recovery of future amounts to be disbursed by the Company. The Company has retained Fundação 
Instituto  de  Pesquisas  Contábeis,  Atuariais  e  Financeiras,  USP  –  “FIPECAFI”  to  validate  the  actual 
values to be reimbursed by the State Government, taking into account the legal advice provided by the 
General Office of the State Attorney provided by the Office of the State Attorney General. 

It  is  not  possible  to  determine  the  net  effects  on  the  balance  sheet  resulting  from  such  negotiation. 
Management  does  not  expect  to  incur  significant  net  losses  relating  to  any  differences  between  the 
amounts recorded as due from the State Government and the amounts expected to be received by Sabesp.

Management  continues  to  believe  that  the  amounts  due  from  the  State  Government  are  collectible  and 
does not expect to incur losses on these accounts receivable. 

The balances for water and sewage services were included in the 1st amendment, as described below (iv). 

(iv)  First Amendment to GESP Agreement 

On  March  22,  2004,  the  Company  and  the  State  Government  amended  the  terms  of  the  original  GESP 
Agreement,  thereby  (1)  consolidating  and  acknowledging  amounts  due  from  the  State  Government  for 
water  and  sewage  services  through  February  2004,  monetarily  adjusted  through  February  2004;  (2) 
formally  providing  for  the  offset  of  amounts  due  from  the  State  Government  against  interest  on 
shareholders’s  equity  declared  by  the  Company  and  any  other  debt  owed  to  the  State  Government  at 
December  31,  2003,  which  were  monetarily  adjusted  through  February  2004;  and  (3)  defining  the 
payment terms of the remaining obligations of the State Government for water and sewage services. 

Under the terms of the Amendment, the State Government acknowledged amounts due to the Company 
for water and sewage services provided through February 2004, in the amount of R$ 581,779, including 
monetary adjustments based on the Reference Rate (“TR”) at the end of each fiscal year through February 
2004.  The  Company  acknowledged  amounts  due  to  the  State  Government  with  respect  to  interest  on 
shareholders’ equity of R$ 518,732, including (1) amounts declared and paid relationg to years prior to 
2003  (R$  126,967),  (2)  monetary  adjustments  on  these  amounts  based  on  the  annual  change  in  the 
Consumer  Prices  Index  (IPC/FIPE)  through  February  2004  (R$  31,098);  and  (3)  amounts  declared  and 
paid relating to 2003 (R$ 360,667). 

The Company and the State Government have agreed to the reciprocal offset of R$ 404,889 (monetarily 
adjusted through February 2004). The remaining obligation of R$ 176,890 at February 29, 2004 will be 
payable  in  monthly  installments  from  May  2005  through  April  2009,  which  will  be  subject  to  monthly 
monetary adjustment at the Expanded Consumer Price Index (IPCA/IBGE), plus 0.5%. 

In 2005 the offset of R$ 105,520 with interest on shareholders’ equity from 2003 occurred, as forecasted. 
In 2006, the Company received the amount of R$ 47,228 corresponding to the installments from January 
through October. On March 2007, the company received the amount of R$ 25,261 corresponding to the 
installments from November 2006 through March 2007. 

The Amendment to the GESP Agreement does not provide for amounts owed by the State Government 
for  supplementary  retirement  and  pension  plan  benefits,  paid  by  the  Company  on  behalf  of  the  State 
Government. Such amounts continue to be subject to the terms of the original GESP Agreement. Part of

such amounts may be netted upon the transfer of the reservoirs that make up the Alto Tietê System. As 
discussed above, the Company and the State Government are negotiating the transfer and netting of the 
additional amounts owed. 

Management  believes  that  the  amounts  owed  by  the  State  Government  shall  be  received  and  it  is  not 
estimated that losses will be incurred with such accounts receivable. Management continues its efforts to 
maintain  in  permanent  basis  the  payments  of  the  State  with  regards  to  the  transactions  between  the 
parties. 

(b) 

Cash and cash equivalents 

The Company’s balance of cash and short-term investments accounts with financial institutions controlled 
by the State Government was R$ 287,999 and R$ 242,021 at December 31, 2006 and 2005, respectively. 
The  financial  income  from  such  investments  was  R$  50,882,  R$  32,293  and  R$  23,114  in  fiscal  years 
ended December 31, 2006, 2005 and 2004, respectively. The Company must, by force of State Decree, 
invest its excess resources together with financial institutions controlled by the State. 

(c) 

Arrangements to use reservoirs 

The Company uses the Guarapiranga and Billings reservoirs and a portion of some of the reservoirs of the 
Alto  Tietê  System,  which  are  owned  by  the  State  Department  of  Water  and  Energy  (DAEE).  The 
Company  does  not  pay  any  fees  with  respect  to  the  use  of  these  reservoirs,  but  is  responsible  for 
maintaining and funding the operating costs of these reservoirs.  The State of São Paulo does not incur 
such  costs  on  behalf  of  the  Company.  In  the  event  these  facilities  had  not  been  made  available  to  the 
Company,  it  would  have  had  to  obtain  water  from  more  distant  sources  which  would  have  been  more 
costly. 

As part of these arrangements, the Company funded approximately R$97,115 of costs for the 1992 and 
1997  projects.  A  portion of  these  project  costs  were  funded  by  the  State  Government,  through   DAEE. 
The agreements included the construction of ducts, tunnels and other facilities to interconnect the Tietê 
River with the Biritiba and Jundiaí reservoirs and other bodies of water in exchange for the Company’s 
use of the reservoirs during a 30-year period.  

The Company has the right to draw water from and release emissions into the reservoirs during a 30-year 
period  which  began  in  1997.  The  Company  capitalizes  expenditures  on  the  facilities  constructed.  The 
assets  relating  to  the  original  reservoir  project  were  placed  in  service  in  1994  and  2002  and  are  being 
depreciated over the remaining term of the original 30 year period. The Company had recorded as part of 
property,  plant  and  equipment  R$  55,660    and  R$  58,397  of  amounts  capitalized  with  respect  to  these 
agreements, net of accumulated depreciation, at December 31, 2006 and 2005, respectively. 

Contracts with reduced Fare for State and Municipal Public Entities that adhere to the Program of 

(d) 
Rational Use of Water 

The Company has entered into contracts with public entities related to the State Government and other 
municipalities  involving  approximately  6,800  properties  that  are  benefited  with  a  25%  tariff  reduction 
for water and sewage services. The contract provides for the implantation of the program of rational use 
of water, which considers the reduction in water consumption.

The State Government and the Brazilian Federal Government, in some cases, provide guarantees of, or 
security  for,  the  Company’s  loans  and  financing.  The  Company  does  not  pay  any  fees  with  respect  to 
these guarantees.

INDEMNITIES RECEIVABLE 

Indemnities Receivable is a non current asset representing amounts receivable from the municipalities of 
Diadema  and  Mauá  as  indemnification  for  the  unilateral  withdraw  of  the  concessions  of  water  and 
sewage services from the Company in 1995. On December 31, 2006 this asset amounted to R$ 148,794. 

Under  these  concession  agreements,  the  Company  invested  in  the  construction  of  water  and  sewage 
systems  in  those  municipalities  in  order  to  meet  its  concession  services  commitments.  Due  to  the 
unilateral  termination  of  the  concessions  of  Diadema  and  Mauá,  the  municipalities  have  assumed  the 
responsibility  to  provide  water  and  sewage  services  in  those  areas.  At  that  moment,  the  Company 
reclassified  the  property,  plant  and  equipment  balances  related  to  the  impounded  assets  used  in  those 
municipalities to non current assets (indemnities receivable) and it has recorded non indemnifiable costs 
in order to reflect the assets by the recoverable amounts contractually estimated as indemnification by 
the Company before the competent authorities. The net book value of the property, plant and equipment 
items  related  to  the  municipality  of  Diadema,  written-off  for  accounting  purposes  in  December  1996, 
was R$ 75,231 and the indemnification balance and other credits receivable from the municipality was 
of  R$ 62,876  on  December  31,  2006.  The  net  book  value  of  the  property,  plant  and  equipment  items 
related to the municipality of Mauá, written-off in the fiscal year 1999, was R$ 103,763, and the balance 
of indemnifications receivable from the municipality was R$ 85,918 on December 31, 2006. 

The Company’s rights to the recovery of these amounts are being disputed by the municipalities and no 
amount has been received up to the date. 

Sabesp  filed  judicial  demands  to  collect  the  amounts  due  by  the  municipalities.  With  regards  to 
Diadema,  the  first  court  level  judge  decided  against  Sabesp,  against  which  there  was  an  appeal  in 
November 2000. On Deceber 1, 2005 a partial acceptance to Sabesp’s appeal was granted to declare the 
validity  of  the  agreement  entered  into  with  the  municipality  of  Diadema.  On  November  11,  2006  the 
City Hall filed special and extraordinary appeals, and on November 21, 2006 the decision allowing the 
Company  to  present  its  responses  to  the  referred  appeals  was  published,  which  has  been  done  on 
December 6, 2006. 

With  regards  to  Mauá,  a  first  court  level  decision  was  given  requiring  that  the  Municipality  pay  an 
amount of R$ 153.2 million as compensation for the loss of profits. This decision was appealed by Mauá 
on April 15, 2005 and it is still pending a decision by the Court of Justice. On July 4, 2006, the sentence 
was  converted  into  a  diligence  comprised  by  an  expert  clarification  about  the  amount  attributed  for 
indemnification purposes, which has not yet been provided by the expert. 

Based on the legal counsel opinion, Management continues to affirm that the Company has legal right to 
receive the amounts corresponding to the indemnification and it continues to monitor the situation of the 
legal proceedings. However, the ultimate amounts to be received, if any, will most likely be subject to a 
final court decision.  As such, actual amounts received could differ from those recorded.

The fixed assets represent the assets involved in the service providing of supply of water and collection 
of  sewage  in  352  municipalities.  In  the  other  municipalities,  which  were  negotiated  by  financial 
economic appraisal, described in the item above, SABESP holds the possession of the assets. 

In  2006,  120  (one  hundred  twenty)  concession  contracts  expired,  being  that  all  of  them  are  under 
negotiation. The net book value of the fixed assets in the Municipalities where the concessions are under 
negotiation (2006) or that will expire in 2007 amounts to R$ 1.94 billion. 

In 2006, the depreciation costs of these municipalities were of R$ 122,785. 

The concession contracts provide that the assets shall turn to the conceding power at the end of the term, 
either  by  means  of  indemnification  by  the  residual  amount  or  market  value  in  accordance  with  the 
established in each agreement. 

 (a) 

Depreciations 

Depreciation  is  calculated  at  the  following  annual  rates:  -  buildings  -  4%,  networks  -  2%,  furniture, 
fixtures  and  equipment  -  10%,  water  meters  -  10%,  vehicles  -  20%,  IT  hardwares  -  20%,  residential 
connections- 5% and office furniture - 10%. 

(b) Disposals of property, plant and equipment 

The Company wrote-off property, plant and equipment in the amount of R$ 54,350, R$ 19,051 and R$ 
34,616 in 2006, 2005 and 2004, respectively. Of these losses, R$ 21,348, R$ 9,879 and 26,034 in 2006, 
2005  and  2004,  respectively,  were  related  to  the  obsolescence,  theft  or  disposal  of  assets  in  use.  The 
remaining  balances  of  losses,  of  R$ 26,459,  R$ 9,172  and  R$ 8,582  were  related  to  the  write-off  of 
construction in progress projects which were determined to be no longer economically feasible. 

Studies supporting the write-offs for obsolescence  and construction-in-progress were concluded by the 
Company  in  the  accounting  period  of  the  write-off,  based  on  undiscounted  cash  flow  projections,  and 
have been approved by Management. The carrying value of property, plant and equipment is monitored 
on an on-going basis and is adjusted, when appropriate, to assure future projected operating revenue is 
sufficient to recover the carrying value of the assets. When applicable, depreciation rates are adjusted to 
take into account changes in estimated remaining economic lives as assets are replaced.

approximately R$ 1,009 million for fiscal years from 2007 to 2012 (unaudited). 

(e)  

Expropriations 

Development of major water and sewage systems frequently requires the expropriation or establishment 
of rights of way through third-party properties. The owners of these properties are generally compensated 
either through negotiated settlements or judicial arbitration. 

Disbursements to be effected as from fiscal year 2007 are estimated to be approximately R$ 467 million 
(unaudited),  which  will  be  paid  out  of  Company  funds.  The  related  assets  acquired  as  a  result  of  these 
negotiations are recorded as property, plant and equipment when the expropriation is complete. In 2006, 
the amount referring to expropriations was R$ 8,385 (2005 - R$ 11,472). 

(f) 

Assets in guarantee 

At  December  31,  2006  and  2005,  the  Company  had  assets  in  the  amount  of  R$  249,034  provided  as 
guarantee under the Special Tax Debt Refinancing Program - PAES (Note 12). 

Additionally,  three  of  the  Company’s  real  estate  properties,  in  the  amount  of  R$ 60,539,  have  been 
pledged  as  guarantee  for  financing  together  with  the  International  Bank  for  Reconstruction  and 
Development - Bird (note 10).

The Company had R$ 26,478 at December 31, 2006 (2005 - R$ 31,832) referring to other non-operating 
assets given as free leases, comprised primarily of lands surrounding reservoirs. 

(h)   Revaluation 

Property,  plant  and  equipment  items  were  revaluated  in  1990  and  1991  and  have  been  depreciated  at 
annual rates which take into consideration the estimated remaining economic useful lives of the assets as 
determined  in  the  respective  valuation  reports  that,  as  a  rule,  fall  within  the  ranges  of  the  above 
presented rates. 

(i) Totally depreciated assets 

On December 31, 2006 the gross accounting value of the totally depreciated assets which are still in use is 
R$ 426,659 (2005 - R$ 336,086).

INTANGIBLE ASSETS 

(a) 

Concessions 

Beginning  in  1999,  negotiations  and  acquisition  of  new  concessions  considers  the  financial  economic 
value of the business, defined in an appraisal report, issued by independent experts. 

The  terms  of  these  concessions  are  generally  for  a  period  of  30  years  and  generally  include  the 
corresponding right to operate the related concession assets for which the Company does not have title. 
The purchase price for these concessions is generally the fair value of the concession, based on appraisal 
reports which take into consideration the projected cash flows and the remaining concession period at the 
date  of  acquisition.  The  cost  of  the  concession  assets  acquired  is  amortized  over  the  concession  period 
using the straight-line method. 
The net disclosed amount refers to the assumption of the following municipalities:

 (i) In current assets 

Mainly calculated on temporary differences in the amount of R$ 20,819 (2005 - R$ 31,557). The tax loss 
carryforwards basis of social contribution accumulated in December 31, 2005 was R$ 142,061 which was 
totally realized in 2006. 

(ii) In long-term assets 

Mainly calculated on temporary differences in the amount of R$ 1,000,985 (2005 - R$ 873,152) related to 
income tax and R$ 1,026,756 (2005 - R$ 894,795) related to social contribution. 

As per a technical feasibility study, the temporary differences mentioned in items (i) and (ii) are likely to 
be realized in 2007. 

(iii) In current liabilities 

Substantially  calculated  on  amounts  invoiced  to  government  agencies,  with  taxes  being  deducted  upon 
receipt of the invoices. 

(iv) In non current liabilities 

-Income tax and social contribution 

Substantially calculated based on temporary differences in the amount of R$ 254,376 (2005 - R$ 248,651) 
relating to income tax and R$ 204,269 (2005 - R$ 198,545) relating to social contribution. 

- Pasep e Cofins 

Substantially calculated on amounts invoiced to government agencies, wich are accrued for when services 
are rendered and wich are paid when the related amounts are effectively received by the Company. 

(c)      Tax effects on the revaluation of assets  

As  permitted  by  CVM  Instruction  197/93,  the  Company  did  not  record  a  provision  for  the  tax  effects 
(deferred taxes) on the surplus of the revaluation of property, plant and equipment carried out in 1990 and 
1991.  Had  the  income  tax  and  social  contribution  on  the  revaluation  reserve  been  accounted  for,  the 
unrealized  amount  at  December  31,  2006  and  2005  would  have  been  R$  430,375  and  R$  461,068, 
respectively.  In  the  years  ended  on  December  31,  2006  and  2005,  the  realized  revaluation  reserve 
amounts were R$ 102,272 and R$ 89,449.

Several  statistical  and  other  factors  that  attempt  to  project  future  events  are  used  in  calculating  the 
expense  and  liability  related  to  the  plans.  These  factors  include  assumptions  about  the  discount  rate, 
expected  return  on  plan  assets  and  the  rate  of  future  salary  increases  as  determined  by  the  Company, 
within certain internal guidelines. In addition, the actuary also uses subjective factors such as termination, 
turnover and mortality rates to estimate these factors. The actuarial assumptions used by the Company are 
reviewed  on  a  regular  basis  and  may  differ  materially  from  actual  results  due  to  changing  market  and 
economic conditions, regulatory events, judicial rulings, higher or lower termination/withdrawal rates or 
longer  or  shorter  life  spans  of  participants.  Such  differences  may  result  in  a  significant  impact  on  the 
amount of pension expense recorded by the Company. 

The assumptions used for the actuarial valuation were as follows:

For 2006 actuarial assessment, the general mortality table has been changed to AT-83 in replacement to 
GAM-1983 table reflects the increase in life expectancy of the population evaluated. 

The number of active participants at December 31, 2006 and 2005 was 16,681 and 16,449 respectively. 
The number of inactive participants at December 31, 2006 and 2005 was 3,692 and 3,326 respectively. 

The  evaluation  of  “SABESPREV”  costing  plan  is  made  by  an  independent  actuarial  expert,  based  on 
different assumptions than those adopted for purposes of ascertaining benefits to employees, as set forth in 
CVM Resolution no. 371. SABESPREV’s technical deficit at December 31, 2006 is R$ 491,391 (2005 - 
R$ 456,861).  Calculation  is  substantially  different  as for  the  actuarial  method  in  calculating  risk  benefits 
before  retirement,  with  sharing  to  “SABESPREV”  and  capitalization  for  the  purpose  of  meeting  CVM 
Resolution  no.  371.  Another  significant  difference  is  the  discount  rate  of  6%  for  “SABESPREV”  and 
12.32% nominal rate for CVM Resolution no. 371, resulting from the combination of a long-term inflation 
rate of 4% per year and actual interest rate of 8%. 

As permitted by CVM Resolution No. 371, the Company has elected to amortize the actuarial liability R$

The Sponsor and the SABESPREV are in process of negotiation so that the technical deficit is resolved, 
by  changing  from  the  Defined  Benefit  Plan  to  Variable  Contribution  Plan.  Management  expects  not  to 
incur in additional costs resulting from the change of the referred plans.

PROFIT SHARING AND BONUS 

As a result of negotiations held by the Company with entities representing the employees, a Profit Sharing 
Program was implemented. For 2005 it was considered the period from July 2005 to June 2006; for 2006, 
the period for goal assessment was changed to January through December, both with the payment of an 
amount corresponding to up to one month’s payroll, in conformity with pre-established goals. 

In  December  2005  the  Company  made  an  advance  payment  of  R$  22,906,  equivalent  to  50%  of  one 
month’s payroll. The payment of the remainder was made in August 2006 in the amount of R$ 25,082. 
The  amount  of  R$ 54,128,  referring  to  the  period  from  January  through  December  2006,  was  paid  in 
February 2007. 

In 2006, the accrued amount corresponds to one and a half month’s payroll, in the amount of R$ 79,489. 
The Company recorded additional salary and payroll charges in the amounts of R$ 44,292 and R$ 40,262, 
for the years ended December 31, 2005 and 2004, respectively 

The Company paid in November, 2006, bonus of R$ 31,035 referring to the performance evaluation for

Approximately 980 customer claims were filed by business customers claiming that their tariffs should be 
equal to those of other categories of consumers and, consequently, claim the refund of amounts imposed 
and charged by the Company. The Company has obtained final decisions, both favorable and adverse, in 
several different court levels, and has recorded provisions for cases with probable risk of loss. In the year 
2006, new customer  claims  were filed in the estimated amount of R$ 46.5  million, as well  as revisions 
and adjustments of already existing suits in the amount approximately of R$ 52.8 million, for the cases 
assessed by the Company’s legal counsels as possible loss.

Lawsuits from municipalities to which the Company provides water in a wholesale basis are not included 
(note 5 (a(iv))). 

(ii) 

Contractor claims 

Certain  construction  service  contractors  have  filed  claims  in  court  alleging  underpayment  of  monetary 
adjustments,  withholding  of  amounts  relating  to  the  effects  of  the  Real  Plan  and  economic-financial 
unbalance of the contract. These lawsuits are in progress in several different court levels, and provisions 
are recorded for cases with probable chance of loss. 

(iii) 

Other civil claims 

The Company is party to several civil claims related to indemnities for moral and material damages and 
loss  of  profits  allegedly  caused  to  third  parties.  In  December  31,  2006  provisions  were  recorded  in  the 
amount of R$ 76,909 (R$ 52,777 in 2005) for claims which risk of loss was assessed as probable.  

(iv) 

Tax Claims  

Provisions for contingencies of tax nature refer mostly to questions related to tax collection, questioned in 
view of divergence in interpretation of the legislation by the Company’s legal counsels. 

In 2006 the Federal Revenue Service, by means of a tax claim, verified the fulfillment, by the Company, 
of tax obligations related to the Income Tax of Legal Entities and Social Contribution on Net Profit for 
the fiscal year 2001, arriving at a tax credit of R$ 277 million. The Company promptly filed its contest 
and shall appeal the tax assessment in all administrative and judicial court levels. According to its legal 
counsels,  approximately  90%  of  this  administrative  lawsuit  is  considered  as  remote  loss  and  10%  as 
possible loss. 

The Company filed a writ of mandamus against the revocation of the exemption from service tax in the 
Municipality  of  São  Paulo,  occurred  by  means  of  municipal  law  enacted  in  2002.  In  April  2003,  the 
request for concession of preliminary injunction was granted determining the suspension of the taxation. 
In  May  2005  the  lower  court  published  a  decision  denying  the  injunction.  In  July  2005,  Sabesp  filed 
appeals  aiming  at  maintaining  the  effectiveness  of  the  injunction  granted.  There  has  not  been  a  final 
decision  about  the  question.  The  amount  involved  is  estimated  in  R$ 70.0  million  and  the  Company, 
based on its legal counsel’s assessment, classifies the risk of loss as possible. 

The  Company  filed  claims  against  the  City  Hall  of  Brangança  Paulista  and  São  Paulo  due  to  the 
imposition of tax on the use of public areas for the installation of water and sewage networks related to 
the  sanitation  services  provided  to  the  municipalities.  In  the  lawsuit  filed  against  the  City  Hall  of 
Bragança Paulista, a preliminary injunction has been granted to the Company suspending the imposition 
of this charge and preventing the City Hall from charging any current or future amounts with respect to 
this charge until there is a final decision of the merits of the cause. In June 2005, the Lower Court ruled in 
favor of the Company and the injunction was maintaned. The City Hall appealed against such decision, 
which is still pending a trial decision. With regards to the claim filed against the City Hall of São Paulo, 
the  First  Level  Court  issued  a  decision  upholding  the  legality  of  this  municipal  tax.  The  Company 
appealed against the court’s decision. An approved law enacted the tax on use of public areas in the city 
of  São  Paulo.  In  April  2004,  the  Company  filed  a  request  for  injunction  seeking  the  suspension  of  the 
assessment  by  the  municipality.  The  preliminary  injunction  was  granted  by  the  First  Level  Court  and 
confirmed at the occasion of the pronounciation of the sentence, recognizing the collection to be undue.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

The City Hall filed an appeal recourse and awaits a decision by the superior court. The Company, based 
on its legal counsel assessment, has not recorded any provision resulting from this municipal tax. 

We  are  a  party  to  a  series  of  lawsuits  initiated  by  the  municipality  of  Ferraz  de  Vasconcelos  in  1997, 
seeking  payment  of  penalties  in  the  aggregate  amount  of  R$71.9  million,  which  we  allegedly  owe  for 
damages  caused  during  construction  in  the  municipality.    Several  of  these  lawsuits  have  already  been 
rejected  by  lower  courts  but  are  still  subject  to  appeal.    We  have  not  made  any  provisions  for  these 
proceedings. 

(v) 

Labor claims 

The  Company  is  party  to  a  number  of  labor  proceedings,  such  as  matters  referring  to  overtime,  health 
hazard, premium claims, prior notice period, job deviation, salary parity and others, with a major portion 
of the amounts claimed under provisional or final execution stage, in several different court levels, and 
thus are classified as probable loss, and duly provisioned for.  

On January 9, 1990, SINTAEMA initiated a lawsuit against us, alleging that we had failed to pay certain 
employee  benefits  and  were  required  to  make  a  penalty  payment  to  SINTAEMA  under  a  then  existing 
collective bargaining agreement.  On July 31, 1992, the labor court issued a ruling against us, but did not 
award damages to SINTAEMA at that time.  We and SINTAEMA are currently engaged in negotiations 
concerning  the  amount  to  be  paid  by  us.    We  also  filed  a  writ  of  mandamus  seeking  a  court  decision 
establishing  that  the  penalty  imposed  against  us,  totaling  approximately  R$6.7  million,  as  of  December 
31, 2006, is excessive since it exceeds the principal amount by a large margin.  Our request was denied by 
the courts and the lawsuit is now awaiting a final decision at the Superior Labor Court (Tribunal Superior 
do Trabalho).  We currently cannot predict the amount that we will be required to pay to SINTAEMA and 
we have not made any provisions for this proceeding.   

On October 6, 1989, SINTAEMA filed a lawsuit against us, asking for the payment of salary differences 
arising  from  additional  payments  due  to  unhealthy  work  conditions  from  September  1987  through 
February 1991.  On December 19, 1997, the Superior Labor Court issued a decision contraryunfavorable 
to  Sabespus.    We  appealed  against  this  decision,  however,  the  decisionit  was  keptmaintained  by  the 
Superior  Labor  Court.    SINTAEMA  started  the  enforcement  of  the  judicial  decision  and  the  valuation 
report of the technical expert of the court was presented on February 21, 2007 in the updated amount of 
R$28.3 million.  Our internal legal counsel considered the risk of loss  as probable and the amount was 
provisioned on December 31, 2006. 

(vi)      Environmental Claims 

Environment  claims  refer  to  several  administrative  proceedings  brought  by  public  agencies,  including 
Companhia de Tecnologia de Saneamento Ambiental - “CETESB” (Environment Sanitation Technology 
Company), seeking to impose fine for environmental damages allegedly caused by the Company. 

Among other matters involving the State of São Paulo Public Attorney’s Office, the following are worthy 
of mention: 

(A) On April 4, 2002, the Company was served process in a public action filed by the District Attorney´s 
Office of the Municipality of São Bernardo do Campo, aiming at repairing damages caused by reason of 
the mud discharge arising from the waste treatment facilities of the Company in current waters, as well as

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

requesting  the  interruption  of  such  discharge.  An  injunction  has  been  granted  determining  that  the 
Company  suspended  the  mud  discharge  and  assessing  a  daily  fine  in  the  amount  of  R$  50  in  case  the 
Company  does  not  comply  with  the  provision  of  such  injunction;  however,  such  injunction  was 
withdrawn. The trial court rendered an affirmative judgment to the Company, against which an appeal has 
been filed. The superior court decided against the Company and ordered it to stop dumping waste within 
one  year  from  the  date  the  decision  is  considered  final,  or  to  pay  a  daily  fine  of  R$ 10,  in  addition  to 
repairing  the  environmental  damage  caused.  The  Company  legal  counsels  assessed  the  risk  of  loss  as 
probable and the provision recorded represents the amount of R$ 141 reflecting the amount attributed to 
the  cause;  (B)  Civil  Public  Action  before  the  Paraguaçu  Paulista  courts  of  law  (1ª  Vara  de  Paraguaçu 
Paulista) seeking compensation and cessation of environmental damages allegedly caused by discharge of 
sewage “in natura” by the Company in Alegre River, located in the Municipality of Paraguaçu Paulista. 
The first instance judge ruled against the Company, requiring that it: (i) ceases the release of raw sewage 
into  the  Alegre  River;  (ii)  invests  in  a  water  and  sewage  treatment  facility  in  the  municipality  of 
Paraguaçu Paulista; and (iii) pays an indemnity for environmental damages arbitrated in the amount of R$ 
116.9 million (the adjusted amount, as of December 31, 2006, was approximately R$ 168.9 million). The 
court decision determined, further, that the non-compliance with items (i) and/or (ii) above would subject 
the Company to the payment of daily fines. The Company filed an appeal against the trial court decision; 
however, the works necessary to meet items (i) and (ii) above have their conclusion estimated to October 
2007. On September 21, 2006, the Court of Justice of the State of São Paulo ruled against the Company’s 
appeal.  Although  the  unfavorable  decision  by  the  Court  of  Justice  of  the  State  of  São  Paulo  is  not 
definitive, the Company is negotiating with the Public Prosecution Office of the State of São Paulo the 
terms and conditions of an agreement that shall result in the extinction of the legal suit. The first deals of 
the agreement resulted in an expectancy of future disbursements in the amount of R$ 20.7 million. In the 
last quarter of 2006, the basis of the agreement was expanded, being included new projects, which total 
the  provision  in  the  amount  of  R$ 33.6  million;  (C)  Civil  Public  Action  against  the  Company  and  the 
Municipality of  Cotia  aiming  at  their  mutual  condemnation:  (a)  to  the  obligation  to  make  consisting  of 
interrupting the disposal of sewage into Cotia River under penalty of daily fines; (b) in the obligation to 
make it consistent and submit to previous treatment all sewages before their discharging into Cotia River, 
under  penalty  of  daily  fine  and  (c)  to  pay  indemnities  for  environmental  damages  caused  to  the  soil, 
hydric resources, superficial and underground bodies of water that cannot be recovered. The First Level 
Court accepted the requests (a) and (c). In the decision settlement, the amount calculated by the judicial 
expert  was  R$ 5.8  million  as  indemnification  for  environmental  damages,  an  amount  that  is  still  under 
discussion and pending to be set up by the First Level Court. The Company’s legal counsels assessed the 
risk of loss as probable; (D) on February 25, 2003, a request for a preliminary injunction was filed for the 
Company  to  immediately  refrain  itself  from  disposing  of  sewage  without  due  treatment,  in  the 
municipality  of  Lutécia,  as  well  as  for  the  purpose  of  determining  that  payments  for  water  and  sewage 
services  by  users  thereof  be  deposited  in  court  until  the  Company  has  fulfilled  the  necessary  plan  of 
investments in the water and sewage system of the municipality, in addition to daily fine in the amount of 
one  thousand  (1,000)  minimum  salaries  (approximately  R$  350)  in  case  of  non-compliance  with  the 
award-making decision. After submission of an expert report, the Public Prosecutor Office requested the 
Company to be sentenced to pay the amount of R$ 82.8 million (the adjustment amount, as of December 
31, 2006, was approximately R$ 119.6 million). The Company, considering the possibility of an eventual 
settlement  with  the  Public  Prosecutor  Office,  condemned  the  area  and  requested  the  respective 
environment licenses, being that its legal counsels assessed the risk of loss as possible; (E) in February 
17,  2003  a  civil  public  action  has  been  filed  before  the  Paraguaçu  Paulista  Courts  referring  to  the 
municipality of Borá, of obligation to do and not do consisting of not discharging and let it be thrown, in 
any way, sewage without due treatment into Borá Brook, or in any other one in the municipality, as well 
as the obligation to do, consisting of investing into the sewage and water treatment system, performing 
immediately  the  necessary  works  for  the  proper  sewage  treatment.  The  anticipated  tutelage  has  been

denied. The judicial expert presented as indemnification for environmental damages the updated amount 
of R$ 48.1 million. The Company’s technical assistant presented impugnation to the expert’s report and 
there is still no decision. The Company carried out the works requested by Cetesb, in order to adequate 
the treatment to the legislation in force. Cetesb, after monitoring, has issued the Operating Permit under 
Provisional Title in August 25, 2006, valid until August 25, 2011. The Company’s legal counsels assessed 
the risk of loss as possible; (F) A civil public action was brought against us by the Coordination Council 
for the Civil Entities of Piracicaba (Conselho Coordenador das Entidades Civis de Piracicaba) concerning 
the  limits  for  water  collection  from  the  Piracicaba  River  and  the  operation  of  the  Cantareira  water 
distribution  system.    The  plaintiff  requests,  among  other  things,  a  prohibitory  injunction  in  order  to 
restrict  the  amount  of  water  we  collect,  the  reduction  of  the  Piracicaba  River’s  collection  limit  and  the 
payment of damages to the riparian cities in order to cover the direct and indirect environmental damages 
caused by the installation and operation of the Cantareira water distribution system.  After our defense, 
the  injunction  was  not  granted,  and  this  action  is  now  awaiting  judgment  by  the  lower  court.    This 
proceeding is still at an initial stage and no amount has been determined so far for the alleged damage.  
We have not made any provisions for this proceeding. 

The Company is involved  in other environmental processes in  municipalities where we operate, arising 
from the discharge of waste without treatment, assessed as probable and possible risk of loss by our legal 
counsels.  The  amounts  provisioned  do  not  always  represent  the  final  amount  to  be  disbursed  as 
indemnification for alleged damages, taking into account the status in which the referred lawsuits are and 
Management’s  impossibility  to  estimate  the  amounts  of  future  disbursements  in  a  reasonable  way.  On 
December 31, 2006 the total provisioned represents the amount of R$ 65,988 already contemplating those 
described on items (A), (B) and (C). 

(vii)  Other proceedings related to the Concession 

In  connection  with  discussions  we  had  with  the  municipality  of  Presidente  Prudente,  we  filed  a  claim 
against the municipality seeking a court decision determining the continuation of the concession contract 
that  we  have  entered  into  with  that  municipality  until  the  indemnification  payment  owed  to  us  in 
connection with the return of water and sewage treatment facility of Presidente Prudente is made.  The 
lower  court  issued  a  decision  in  our  favor  to  the  effect  that  we  still  continue  to  provide  services  in  the 
municipality until the indemnification provided for in the concession contract is paid to us.  

On March 25, 2004, the Public Attorney’s Office filed a civil action against the municipality of Itapira, its 
mayor,  the  Municipal  House  of  Representatives  and  us,  claiming  that  Municipal  Law  No.  3,593/04  is 
unconstitutional and seeking termination of the concession contract we entered into with the municipality 
of Itapira.  Although an injunction was granted, the Court of Justice of the State of São Paulo has stayed 
the injunction.  On March 23, 2005, the House of Representatives of Itapira approved a decree revoking 
the concession contract.  In addition, Municipal Law No. 3,730/05 was enacted revoking an earlier law 
which  authorized  the  municipality  to  enter  into  the  concession  contract  with  us.    The  municipality  of 
Itapira has further filed an action against us seeking to repossess the assets related to its water and sewage 
services  and  has  obtained  an  injunction  which  was  later  confirmed  by  a  court  decision.    We  appealed 
against this ruling but we have not been able to suspend the effects of the decision until final judgment.  
Accordingly, we are currently not rendering water and sewage services at Itapira.  As of the date of this 
annual report, a trial decision on this litigation was pending.  We have not made any provisions for this 
proceeding. 

On  October  10,  2003,  the  municipality  of  Monte  Mor  filed  a  lawsuit  against  us,  seeking  the  additional 
issuance  and  delivery  of  shares  by  us,  as  consideration  for  our  concession  to  render  basic  water  and

sewage services.  The lawsuit was dismissed without judgment on the merits of the case.  We have not 
made any provisions for this proceeding. 

The  municipality  of  Sandovalina  has  brought  a  legal  action  against  us  seeking  to  (1)  obtain  the 
termination of the concession entered into with us and (2) obtain remedies for environmental damage and 
alleged losses caused to the municipality due to our failure to provide sewage treatment, as well as other 
damage caused to public property.  We have responded with a counterclaim against the municipality for 
payment of R$115 related to the supply of water from December 1999 through August 2003.  We are also 
seeking the payment of a contractual indemnification based on the early termination of the contract.  We 
are currently operating the water and sewage treatment facility of Sandovalina, and the lawsuit is still in 
the fact-finding phase.  We have not made any provisions for this proceeding.  

We are also defendants in legal proceedings initiated by municipalities seeking to require us to produce 
documents  and  information  in  connection  with  our  concessions.    These  legal  proceedings  include  the 
following:  (1) a preliminary proceeding (ação cautelar) started by the municipality of Guariba seeking a 
court order requiring us to produce documents in order to inform an account revision proceeding; (2) the 
municipality  of  Ribeirão  Pires  has  proposed  preliminary  proceedings  seeking  the  production  of 
documents  to  inspect  the  services  which  we  provide;  (3)  the  municipalities  of  Itupeva  and  Monte  Mor 
have  proposed  proceedings  seeking  to  obtain  a  court  order  to  require  us  to  produce  documents  and 
information in order to evaluate the possibility of renewal of our concession agreement. 

In December 1997, the municipality of Santos enacted a law expropriating our water and sewage systems 
in  Santos.    In  response,  we  filed  an  action  seeking  an  injunction  against  this  expropriation,  which  was 
denied by the lower court.  This decision was later reversed by the Court of Justice of the State of São 
Paulo,  which  issued  a  preliminary  order  suspending  that  law.    On  August  2,  2002,  a  decision  on  this 
matter was rendered in our favor by a lower court, but that decision remains subject to appeal.  Despite 
the pending lawsuit, we continue to provide water and sewage services to Santos.  

We  are  a  party  to  a  substantial  number  of  other  legal  proceedings,  in  addition  to  the  lawsuits  and 
administrative  proceedings  discussed  above,  in  the  normal  course  of  our  business.    These  legal 
proceedings include personal injury and property damage cases, environmental proceedings, challenges to 
our  ability to cease  rendering water  and sewage  services upon default by our customers and  a  range of 
other matters.  We have not established provisions with respect to these other legal proceedings.

 (c) 

Distribution of earnings 

Shareholders are entitled to a mandatory minimum dividend distribution of 25% of adjusted net income, 
calculated in conformity with Brazilian Corporate Law.  This requirement can be met through payments 
made in the form of dividends and interest on shareholders’ equity (net of withholding tax), to the extent 
amounts  are  available  for  distribution.  Dividend  distributions  are  limited  to  retained  earnings  as 
determined  in  accordance  with  BR  CL.  At  December  31,  2006,  as  required  by  the  CVM,  management 
designated the retained earnings balance to a discretionary investment reserve account (see (e) below). 

For purposes of BR CL, and in accordance with the by-laws of the Company, adjusted annual net income 
is  an  amount  equal  to  the  Company’s  annual  net  income  adjusted  to  reflect  allocations  to  or  from  (i) 
statutory  legal  reserve,  (ii)  an  equity  contingency  reserve  for  anticipated  losses,  if  any,  and  (iii)  an 
unrealized revenue reserve, if any. The calculation of the mandatory minimum dividends for 2006 is as 
follows: 

Net income for the year

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

The Company by-laws also provide for distribution of interest on shareholders’  equity as an alternative 
form  of  distribution to  shareholders.  The  interest  rate  is  limited  to  the  variation  in  the  TJLP  during  the 
applicable period and the deductible distribution cannot exceed the greater of 50% of net income (before 
distribution and deductions for income taxes) for the period or 50% of retained earnings. Distribution of 
interest on  shareholders’  equity is a tax-deductible  expense  for both income  tax and  social contribution 
purposes. The amount paid to shareholders as interest on shareholders’ equity, net of any withholding tax, 
is taken into account in determining the mandatory dividend. 

The  Company  declared  interest  on  shareholders’  equity,  in  lieu  of  dividends,  in  the  amount  of 
R$ 251,238, net of withheld income tax in the amount of R$ 19,603 in 2006. In 2005, the amount was R$ 
324,461  net  of  income  tax  of  R$ 23,755.  Interest  on  shareholders’  equity  was  calculated  in  conformity 
with  with  article  9  of  Law  No.  9.249/95,  at  the  Long-Term  Interest  Rate  (TJLP);  this  interest  was 
originally  recorded  in  “Financial  expenses”  for  income  and  social  contribution  tax  purposes  and 
subsequently, for presentation purposes, was reflected directly in “Shareholders’ equity”. 

The  amounts  due  to  the  major  shareholder  relating  to  the  years  2004  to  2006  have  not  been  paid,  as 
mentioned in note 6. 

(d) 

Capital reserves 

Capital  reserve  comprises  tax  incentives  and  donations  from  government  agencies  and  private  entities, 
which amounted to R$ 27,870 during the year 2006 (R$ 13,529 in 2005). 

The tax incentive reserve results from an option to invest in the capital stock of companies undertaking 
specified  government-approved  projects.  In  lieu  of  paying  part  of  the  income  tax  due,  the  amount  is 
credited to income tax and subsequently appropriated from retained earnings to this reserve. 

The donations reserve reflects the value of assets received from government entities, principally enabling 
the  Company  to  provide  service  access  to  properties.  No  shares  are  issued  in  exchange  nor  other 
remuneration  provided  in  connection  with  assets  received.  These  donations  are  recorded  as  a  direct 
benefit to shareholders’ equity. 

(e) Investment reserve 

Management  proposed  to  transfer  the  balance  of  retained  earnings  not  distributed  to  shareholders  to  a 
discretionary  reserve  (investment  reserve)  in  accordance  with  the  Company’s  capital  expenditure 
program. 

The  following  summarizes  the  allocation  of  net  income  to  the  investment  reserve  for  the  years  ended 
December 31,

Management will propose to transfer the balance of retained earnings in the amount of R$ 571,390 to the 
“Investment Reserve” account in order to meet the needs for investments out of own funds, as provided 
for in the Capital Budget. 

(f)     Legal (statutory) reserve 

Under  Brazilian  Corporate  Law,  the  Company  is  required  to  record  a  legal  reserve  to  which  it  must 
allocate 5% of the adjusted net income each year until the amount of the reserve equals 20% of paid-in 
capital.  Accumulated deficit, if any, may be charged against the legal reserve.

FINANCIAL INSTRUMENTS AND RISK 

(a) Valuation of Financial Instruments 

In accordance with CVM Instruction No. 235/95, the Company has determined the market values of its 
assets  and  liabilities  based  on  available  information  and  appropriate  valuation  methodologies.    Market 
values and book values of the Company’s financial  instruments at December  31, 2006  and  2005  are  as

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

The main financial instruments, assets or liabilities of the Company, on December 31, 2006 are described 
as follows, as well as their valuation criteria: 

(i) Financial Investments: The market value of these assets does not differ from the amounts demonstrated 
in the Company’s balance sheets. 

(ii)  Loans,  Financings  and  debentures  (5th  issue,  2nd  series;  6th  issue,  2nd  and  3rd  series  and  7th  and  8th 
issues, 2nd series), with financial instruments with the same characteristics in the market, had the market 
value determined based on the discounted cash flow, using interest rates projections available. The remain 
loans  and  financings  were  not  marked  to  market  either  for  being  financial  instruments  with  exclusive 
characteristics  (without  corresponding  ones  in  the  market)  or  for  which  no  material  difference  between 
the market value and the book value exist, as they are indexed to the CDI which is a floating rate used in 
the market. 

(b) Exchange rate risks 

Exchange rate risk is the risk that the Company may incur losses due to exchange rate fluctuations, which 
could increase the liability balances and related financial expenses of loans and financing denominated in 
foreign currencies funded in the market and, consequently, the financial expenses. The Company does not 
enter into hedge or swap transactions, however, at times, it enters into forward exchange transaction and 
financial funding transactions to mitigate foreign currency exposure, taking advantage of opportunities in 
order to exchange them for less expensive debts, reducing the cost by means of advancing maturities. 

A significant portion of the Company’s debt is denominated in foreign currency, primarily the US dollar 
and the Yen, totaling R$ 1,472,768 (note 10). The Company’s net exposure to the exchange rate risk at 
December 31, 2006 is summarized as follows:

December 31, 2005 

US$ 

666,890 

€

Loans and financing 

(c) Interest rate risks 

This risk arises out of the possibility for the Company to incur losses due to interest rates fluctuations that 
would increase its financial expenses related to loans and financing. The Company has not entered into 
hedge  agreements  to  mitigate  such  risk.  The  Company  does,  however,  continually  monitors  market 
interest  rates  in  order  to  evaluate  the  possible  need  to  replace  or  refinance  its  debt.  On  December  31, 
2006, the Company had loans and financing in the amount of R$ 1,283,197 (R$ 1,327,694 in 2005), at 
variable interest rates (CDI and TJLP). 

Another risk faced by the company is that the monetary adjustments of its debts are not correlated to the 
accounts receivable. The Company’s related water and sewage tariff rates are not necessarily correlated 
with the increases in the interest rates and price-level restatement indexes associated with the Company’s 
debt.

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

The  Company  manages  credit  risk  principally  by  selling  to  a  geographically  dispersed  customer  base, 
including sales to municipal governments. 

No single customer represented more than 10% of the Company’s sales and services rendered in the years 
ended December 31, 2006, 2005, and 2004. 

(e)     Drought weather risk 

The atypical meteorogical conditions for the past three years, resulted in the need to launch institutional 
campaigns to encourage economical and rational use of water, which has led to a decrease in billed water 
volumes.  At  the  same  time,  higher  investments  were  required  to  mitigate  the  drought  effects  on  the 
Company’s water production systems. This drought period has required a reduction in water supply, with 
a  consequent  reduction  in  water  volumes  billed.  In  view  of  the  present  levels  of  the  reservoirs,  no 
rationing is estimated to occur in 2006.

(i) Comprises the municipalities served in the country side and coastal area of the State of São Paulo 

In  October  2003,  the  Company  launched  a  new  campaign  “Watch  the  Water  Level”,  involving 
advertisements  in  all  media,  together  with  a  program  consisting  of  discounts  to  customers  who  reduce 
their water consumption for the period from March to September 2004, by at least 20%, in relation to the 
average  consumption  determined  by  the  Company.  The  Incentive  Program  for  Water  Consumption 
Reduction was implemented in the Metropolitan Region of São Paulo. 

The program resulted in a reduction of R$ 74.1 million in the revenue from water and sewage services in 
the Metropolitan Region of São Paulo during its effective period.

SUMMARY OF DIFFERENCES BETWEEN BR CL AND US GAAP 

The  Company’s  primary  financial  statements  have  been  prepared  in  accordance  with  BR  CL 
which differs significantly from US GAAP as described below: 

(a)  Inflation accounting methodology and indices 

In  Brazil,  because  of  highly  inflationary  conditions  which  prevailed  in  the  past,  a  form  of 
inflation accounting had been in use for many years to minimize the impact of the distortions in 
financial statements caused by inflation. Two methods of inflation accounting were developed: 
one required under BR CL; and the other known as the Constant Currency Method. The primary 
difference  between  BR  CL  and  the  Constant  Currency  Method  relates  to  accounting  for  the 
effects  of  inflation.  Under  BR  CL,  inflation  accounting  was  discontinued  effective  January  1, 
1996.  Prior  to  that  date,  BR  CL  required  inflationary  indexation  of  property,  plant  and 
equipment, investments, deferred charges and shareholders' equity, the net effect of which was 
reported in the statement of operations as a single line item. The Constant Currency Method is 
similar to U.S. Accounting Principles Board Statement No. 3 ("APS 3"), except that the former 
continues  to  apply  inflationary  accounting  in  periods  of  low  inflation.  Under  US GAAP,  the 
Brazilian economy ceased to be highly inflationary effective July 1, 1997. The other significant 
difference between the two sets of principles relates to the present-value discounting of fixed-
rate  receivables  and  payables,  which  is  required  by  the  Constant  Currency  Method  and  is 
prohibited under BR CL. 

Financial  statements  prepared  in  accordance  with  BR  CL  have  been,  and  continue  to  be, 
required  of  all  Brazilian  corporate  entities  and  are  used  by  the  Brazilian  tax  authorities  in 
determining  taxable  income.  Financial  statements  prepared  in  accordance  with  the  constant 
currency method were required through 1995 for those entities whose securities were registered 
with  the  CVM.  Since  1996,  presentation  of  supplemental  financial  statements  under  the 
Constant Currency Method has been optional. 

(i)  Additional inflation restatement in 1996 and 1997 for US GAAP 

In the reconciliation from BR CL to US GAAP, consistent with the position paper prepared 
by  the  U.S.  AICPA  International  Practice  Task  Force,  an  adjustment  for  inflation 
accounting has been included for the period from January 1, 1996 to December 31, 1997. 
During  this  period,  inflation  accounting  was  prohibited  by  BR  CL  but  was  required  by 
APB statement 3 under US GAAP. Shareholders' equity under US GAAP was increased by 
R$ 1,171,576 and R$ 1,247,117 at December 31, 2006 and 2005, respectively,  due to the 
additional inflation restatement adjustments. 

(ii)  Supplementary inflation restatement replaces revaluation of property, plant and equipment 

for US GAAP

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

The price-level restatement methodology under BR CL relied on an official inflation index 
announced  by  the  Brazilian  Federal  government  which  was  also  used  for  purposes  of 
determining  taxes  payable.  Shortly  after  the  launch  of  an  economic  stabilization  plan  in 
1990,  the  government  announced  an  inflation  rate  for  that  year  which  was  materially 
understated  in  relation  to  the  general  and  consumer  price  indexes  as  measured  by 
independent  economic  institutes.  In  1991,  the  government  acknowledged  this  distortion 
and  companies  were  required  to  re-present  their  statutory  financial  statements  using  a 
revised inflation index and the effects  thereof were  also used to  determine income taxes, 
retroactively.  The  same  law  (Law No.  8,200/91)  also  granted  companies  the  option  (and 
the  CVM  required  adoption  when  the  effects  were  significant)  to  reprocess  the 
accumulated inflation accounting effects since the date of acquisition of assets based on an 
independently  sourced  consumer  or  general  price  index.  This  supplemental  indexation  of 
property, plant and equipment, investments and deferred charges was to be recorded in the 
statutory  BR  CL  accounting  books  but  would  have  no  effect  for  tax  purposes.  The 
Company  anticipated  the  effects  of  this  measure  by  contracting  an  independent  firm  of 
experts  to  perform  an  appraisal  to  market  value  of its  property,  plant  and  equipment  and 
recorded  the  revaluation  increment  in  its  statutory  BR  CL  accounting  records,  without 
affecting its tax position, in much the same way as Law No. 8,200/91 later required. As the 
revaluation  increment  had  eliminated  the  effects  of  the  supplemental  price-level 
restatements, no further action was taken and the Company did not apply the incremental 
indexation. 

Under US GAAP, revaluations of assets to market value are not permitted and the effects 
of the revaluation have been reversed in the reconciliation to US GAAP. However, in order 
to  preserve  the  integrity  of  the  historical  cost  of  its  assets  based  on  the  price-level 
restatement  convention  adopted  by  BR  CL,  the  Company  has  recorded  the  supplemental 
price-level restatement adjustments, in accordance with Article 2 of Law No. 8,200/91, as 
an  adjusting  item  in  the  reconciliation  to  US  GAAP.  The  Company  has  presented  the 
balances of shareholders' equity and net income under BR CL, adjusted for the effects of 
the  revaluation  and  the  replacement  of  the  reversal  by  the  supplemental  price-level 
restatements, and related tax effects, as a subtotal, prior to presenting the reconciling items 
to US GAAP. The subtotal also includes the effects of including an additional two years' 
inflation accounting adjustments through to 1997 for purposes of US GAAP.  

Shareholders' equity under US GAAP was increased by R$ 2,806,638 and R$ 2,924,881 at 
December 31, 2006 and 2005, respectively, due to the supplementary inflation restatement 
adjustments  and  reduced  by  R$  2,427,499  and  R$  2,529,771  at  December  31,  2006  and 
2005, respectively, due to the reversal of the revaluations, before tax effects. 

(iii)  Inflation indexes 

The indexation of the financial statements through 1995, except for the year 1990, under 
BR  CL  was  based  on  an  official  government  index,  the  Unidade  Fiscal  de  Referência  - 
UFIR  and  for  the  year  ended  December  31,  1990  on  a  consumer  price  index  (Índice  de 
Preços  ao  Consumidor,  or  IPC).  For  purposes  of  US  GAAP,  a  general  price  index,  the 
Índice Geral de Preços - Mercado, or IGP-M, was used to record the additional inflation 
restatement in 1996 and 1997 and the supplementary inflation restatement through 1995.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

(b)  Income taxes and social contribution 

Under  BR  CL,  deferred  tax  assets  are  recognized  at  the  estimated  amounts  that  management 
considers  are  probable  to  be  recovered.  In  addition,  deferred  income  taxes  are  shown  gross 
rather than net. 

Under  US  GAAP,  deferred  taxes  are  recorded  on  all  temporary  tax  differences.  Valuation 
allowances are established when it is more likely than not that deferred tax assets, including tax 
loss  carryforwards,  will  not  be  recovered.  Deferred  tax  assets  and  liabilities  are  classified  as 
current or long-term based on the classification of the asset or liability underlying the temporary 
difference, and are presented net. 

For  purposes  of  deferred  tax  accounting,  the  US  GAAP  adjustments  relating  to  inflation 
restatement  of  land  and  the  push-down  expenses  from  the  Plan  G0  pension  fund  (j)(ii)  below 
and sabbatical paid leave benefits are treated as permanent tax differences, as such items are not 
deductible for tax purposes by the Company.  

Taxes on income in Brazil consist of two types of taxes: income tax and social contribution. In 
Brazil,  the  tax  law  and  tax  rates  are  sometimes  significantly  altered  by  provisional  measures 
("medidas provisórias") announced by Presidential decree. The provisional measures can affect 
tax  rates  as  well  as  other  areas  that  could  impact  deferred  taxes.  Until  September  2001,  these 
measures remained in force for one month and expired automatically if they were not extended 
for  an  additional  one-month  period.  In  September  2001  all  provisional  measures  were 
automatically  enacted,  and  the  Presidential  decree  powers  restricted.  Under  BR  CL,  when 
calculating deferred income taxes, the provisional measures are usually taken into account. 

Under US GAAP, only enacted tax rates may be used to calculate deferred taxes. Tax rates for 
future periods which have been established by provisional measures are not considered to have 
been enacted and are ignored. However, the provisional measure, to the extent it has not lapsed, 
is used for determining the amount of current tax payable.  

Shareholders'  equity  under  US  GAAP  was  reduced  by  R$  1,356,545  and  R$  1,304,723  at 
December  31,  2006  and  2005,  respectively,  due  to  deferred  tax  adjustments  on  US  GAAP 
differences, excluding revaluations and permanent differences related to monetary readjustment 
on land of approximately R$ 150.0 million. 

No valuation allowance adjustments were required to be included in the reconciliation between 
BR CL and US GAAP. 

(c)  Financial instruments and concentration of credit risk 

Under BR  CL, there are less detailed requirements regarding the disclosure of information  on 
financial  instruments  not  reflected  on  the  balance  sheet  or  on  concentration  of  financial 
instruments with credit risk. 

Under  US  GAAP,  the  applicable  accounting  practice  for  financial  instruments  depends  on 
management's  intention  for  their  disposition  and  requires  adjustments  to  their  market  or  fair

values.  Additional  information  on  face  or  contract  or  notional  principal  amount;  nature  and 
terms  including  (i)  credit  and  market  risk,  (ii)  cash  requirements  and  (iii)  accounting  policy 
followed; amount of loss, if any party to the financial instrument fails to perform; and policy as 
to requiring collateral is required. Disclosure as to concentration of credit risk arising from all 
financial  instruments  is  required  to  include  information  about  the  activity,  region  or  other 
characteristic that identifies the concentration; amount of loss if parties to the concentrated risk 
fail to completely perform; and policy as to requiring collateral. 

Statement  of  Financial  Accounting  Standards  ("SFAS")  No.  133,  "Accounting  for  Derivative 
Instruments  and  Hedging  Activities"  of  the  U.S.  Financial  Accounting  Standards  Board 
(“FASB”)  establishes  accounting  and  reporting  standards  for  derivative  instruments  and  for 
hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities 
and measure those instruments at fair value. This statement was effective January 1, 2001 and 
did not have a significant impact on the Company’s financial statements. 

No adjustments have been included in the reconciliation from BR CL to US GAAP. 

(d)  Cash and cash equivalents  

Under BR CL, cash equivalents are not defined. 

Under  US  GAAP,  SFAS  No.  95,  "Statement  of  Cash  Flows",  defines  cash  equivalents  as  short-term 
highly liquid investments that are both (i) readily convertible to known amounts of cash and (ii) so near 
their maturity that they present insignificant risk of changes in value because of changes in interest rates. 
Generally, only investments with original maturities of three months or less qualify under that definition 
The Company holds certain highly liquid, low risk financial investments, comprised principally of high 
quality  government  debt,  which  are  classified  as  cash  equivalents  under  BR  GAAP.  Although  the 
investments  have  high  level  of  liquidity  and  present  insignificant  risks  of  changes  in  value,  under  US 
GAAP, since these investments have original maturities of over 90 days, such investments do not qualify 
as cash equivalents. The effect of this difference in classification on the Company’s balance sheets and 
statements of cash flows for the periods presented are as follows:

Under  BR  CL,  marketable  debt  and  equity  securities  are  generally  stated  at  the  lower  of 
inflation-indexed amortized cost or market value less interest or dividends received. Gains and 
losses are reflected in earnings. 

Under US GAAP, in accordance with SFAS No. 115, "Accounting for Certain Investments in 
Debt  and  Equity  Securities",  the  accounting  and  reporting  for  investments  in  equity  securities 
that have readily determinable fair values and for all investments in debt securities is as follows: 

(i)  Debt securities that the enterprise has the positive intent and ability to hold to maturity are 

classified as held-to-maturity securities and are reported at amortized cost. 

(ii)  Debt  and equity securities that are bought and held principally for  the  purpose of selling 
them  in  the  near  term  are  classified  as  trading  securities  and  reported  at  fair  value,  with 
unrealized gains and losses included in earnings. 

(iii)  Debt and equity securities not classified as either held to maturity or trading securities are 
classified as  available for  sale securities and reported  at fair  value,  with unrealized gains 
and losses excluded from earnings and reported in a separate component of shareholders' 
equity. 

For purposes of US GAAP, certain unrealized gains and losses from the Company’s available-
for-sale securities are recorded directly in shareholders' equity, net of tax effects, until realized. 
Shareholders' equity under US GAAP was reduced by R$ 93 and R$ 30 at December 31, 2006 
and 2005, respectively, for unrealized losses from available-for-sale securities. 

(f)  Property, plant and equipment 

(i)  Revaluations of property, plant and equipment 

BR  CL  permits  appraisal  write-ups,  provided  that  certain  formalities  are  complied  with. 
The  revaluation  increment  is  credited  to  a  reserve  account  in  shareholders'  equity. 
Depreciation  of  the  asset  revaluation  increments  is  charged  to  income  and  an  offsetting 
portion  is  relieved  from  the  revaluation  reserve  in  shareholders'  equity  and  transferred  to 
retained earnings as the related assets are depreciated or are disposed

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

For US GAAP reconciliation purposes, net revaluation of property, plant and equipment in 
the  amounts  of  R$  2,427,499  and  R$  2,529,771  at  December  31,  2006  and  2005, 
respectively,  have  been  eliminated  in  order  to  present  property,  plant  and  equipment  at 
historical  cost,  indexed  for  inflation  through  1997  based  on  a  general  price  index,  less 
accumulated  depreciation.  The  depreciation  on  such  revaluation  charged  to  income, 
totaling R$ 102,272, R$ 89,449 and R$ 104,500 for the years ended December 31, 2006, 
2005  and  2004,  respectively,  has  also  been  eliminated  for  US  GAAP  purposes  in  the 
reconciliation of net income. 

Under BR CL, no deferred tax liability was recorded on the revaluation increment. Under 
US GAAP,  although  the  depreciation  from  the  additional  inflation  restatement  ((a)(i) 
above)  and  the  supplementary  inflation  restatement  ((a)(ii)  above)  will  not  be  deductible 
for tax purposes, these depreciation charges are considered to be temporary tax differences 
as  the  expense  will  reverse  through  income  in  the  future,  and,  as  such,  are  recorded  for 
purposes of determining deferred tax liabilities. 

(ii)  Different criteria for capitalizing and depreciating capitalized interest 

Under BR CL, until December 31, 1995, capitalization of interest cost incurred during the 
construction period as part of the cost of the related property, plant and equipment was not 
required. However, as permitted by the Brazilian Water and Sewage Plan (Plano Nacional 
de  Saneamento  Básico  -  PLANASA),  SABESP  capitalized  interest  on  construction-in-
progress  through  1989.  Also,  under  BR  CL  as  applied  to  companies  in  the  utilities 
industry,  during  the  period  from  1979  to  1985,  a  notional  interest  rate  was  applied  to 
construction-in-progress  computed  at  the  rate  of  12%  per  annum  of  the  balance  of 
construction-in-progress;  that  part  which  related  to  interest  on  third-party  loans  was 
credited to interest expense based on actual interest costs with the balance relating to the 
self-financing portion being credited to capital reserves. Beginning in 1999, SABESP has 
capitalized  indexation  charges  on  the  real  -  denominated  loans  and  financing  and  the 
foreign exchange effects on foreign currency loans and financing. 

Under  US  GAAP,  in  accordance  with  SFAS  No.  34,  "Capitalization  of  Interest  Cost", 
interest incurred on borrowings is capitalized to the extent that borrowings do not exceed 
construction-in-progress. Such interest is capitalized as part of the cost of the related assets 
with a corresponding credit to financial expenses. Under US GAAP, the amount of interest 
capitalized excludes the indexation charges associated with the borrowings and the foreign 
exchange gains and losses on foreign currency borrowings.  

The effects of these different criteria for capitalizing and amortizing interest are presented 
below:

(iii)  Valuation of long-lived assets 

Under  BR  CL,  companies  are  required  to  determine  if  operating  income  is  sufficient  to 
absorb  the  depreciation  or  amortization  of  long-lived  assets,  within  the  context  of  the 
balance  sheet  as  a  whole,  in  order  to  assess  potential  asset  impairment.  As  it  pertains  to 
property,  plant  and  equipment,  in  the  event  that  such  operating  income  is  insufficient  to 
recover the depreciation due to their permanent impairment, the assets, or groups of assets, 
are written-down to recoverable values, preferably, based on the projected discounted cash 
flows of future operations. 

Under US  GAAP, SFAS No. 144, "Accounting  for the Impairment or Disposal of Long-
lived Assets", requires companies to periodically evaluate the carrying value of long-lived 
assets  to  be  held  and  used,  and  for  long  lived  assets  to  be  disposed  of,  when  events  and 
circumstances require such a review. The carrying value of long-lived assets is considered 
impaired when the anticipated undiscounted cash flows from identified assets, representing 
the lowest level for which identifiable cash flows largely independent of the cash flows of 
other groups of assets and liabilities, is less than their carrying value. In that event, a loss is 
recognized to the extent that the carrying value exceeds the fair market value of the assets. 

No adjustment has been included in the reconciliation from BR CL to US GAAP to take 
account  of  differences  between  the  measurement  criteria,  as  based  on  analysis  of  cash 
flows measured at the smallest unit of assets groups for which cash flow data is captured 
no  impairment  provisions  were  required.  Losses  recognized  on  the  write-off  of  property, 
plant  and  equipment  arose  primarily  from  adjustments  related  to  the  withdrawal  of 
concession  assets,  construction-in-progress  projects  which  were  deemed  to  be  no  longer 
economically feasible and obsolescence write offs.

Under  BR  CL  deferral  of  feasibility  study  costs  and  pre-operating  expenses  incurred  in  the 
construction  or  expansion  of  a  new  facility  is  permitted  until  such  time  as  the  facility  begins 
commercial operations. Deferred charges are amortized over a period of five to ten years. 

Under  US  GAAP,  such  amounts  do  not  meet  the  conditions  established  for  deferral  and 
accordingly are charged to income as incurred. 

The  balance  of  feasibility  study  costs  outstanding,  amounted  to  R$  10,035  and  R$  20,531  at 
December 31, 2006 and 2005, respectively,  was  written-off for US  GAAP purposes.  The  net 
effects  from  amortization  and  deferrals  in  the  statement  of  operations  at  December  31,  2006,

2005 and 2004 were an increase of R$ 10,496, R$ 18,566 and R$ 9,854 respectively.  

(h)  Dismissal encouragement program 

In December 2003 the Company announced a one-time, special dismissal encouragement / early 
retirement  program.  Under  BR  CL,  the  total  estimated  termination  benefits  for  all  employees 
who would formally accept the offer were accrued for at December 31, 2003. Under US GAAP, 
such  benefits  are  considered  special  termination  benefits,  as  defined  in  SFAS  No.  88, 
“Employers' Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and 
for Termination Benefits” and as such, are only allowed to be accrued as an expense when an 
employee  accepts  the  offer.  At  December  31,  2003,  approximately  330  employees  had 
requested to apply to enter the dismissal encouragement program. In the reconciliation between 
BR  CL  and  US  GAAP,  the  difference  between  the  estimated  benefits  under  BR  CL  and  the 
estimated  benefits  associated  with  those  employees  who  had  accepted  offers  at  December  31, 
2003 has been reversed for US GAAP. Such  benefits were accrued and expensed in  2004. At 
December 31, 2004, 711 employees entered this program and the Company had paid R$ 29,409. 

(i)  Pension benefits 

Under BR CL, prior to 2002, amounts related to the pension plan were recorded on an accrual 
basis as the obligations for contributions fell due. In accordance with a new accounting standard 
issued  by  IBRACON  and  approved  by  the  CVM,  effective  January  1,  2002,  Brazilian  public 
companies  must  account  for  pension  obligations  based  on  actuarial  calculations  and  provide 
certain disclosures related to their pension plans. Under the new standard, the actuarial pension 
obligation determined at the date of adoption could be either recorded directly in shareholders’ 
equity,  or  prospectively,  during  the  five-year  period  ending  December  31,  2006  in  results  of 
operations. As permitted, the Company has elected to recognize this transition obligation on a 
straight-line  basis  through  income  over  five  years  beginning  in  2002.  The  amortization  of  the 
liability  is  being  presented  as  an  “Extraordinary  item”  in  the  statements  of  operations,  net  of 
applicable tax effects.  

Under US GAAP, the Company accounts for its pension plans in accordance with the provisions 
of  SFAS  No.  87,  "Employers'  Accounting  for  Pensions,"  which  among  other  requirements, 
requires  that  the  Company  recognize  the  actuarially-determined  liability  of  its  pension  plan 
obligations. SFAS No. 87 also requires that an additional liability (minimum pension liability) is 
required to be recorded when the accumulated  benefit obligation  exceeds the fair value  of the 
plan  assets,  less  accrued  pension  amounts.  This  additional  minimum  liability  is  recorded  as  a 
charge to accumulated other comprehensive income in equity.  

SFAS  No.  132  (revised  2003),  “Employers'  Disclosures  about  Pensions  and  Other 
Postretirement Benefits” sets forth the requirements for information that must be disclosed with 
respect to the Company’s pension plans. 

After  the  issuance  of  SFAS  158  “Employers’  Accounting  for  Defined  Benefit  Pension  and 
Other Postretirement Plans an amendment of FASB Statements No. 87, 88, 106, and 132(R)”, in 
September 2006, an employer is required to recognize the overfunded or underfunded status of a 
defined benefit postretirement plan (other than a multi-employer plan) as an asset or liability in 
its statement of financial position and to recognize changes in that funded status in the year in 
which  the  changes  occur  through  comprehensive  income  of  a  business  entity  or  changes  in

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

unrestricted net assets of a not-for-profit organization. This Statement also requires an employer 
to  measure  the  funded  status  of  a  plan  as  of  the  date  of  its  year-end  statement  of  financial 
position, with limited exceptions.  

Another requirement of the statement is that the employer must disclose in the notes to financial 
statements additional information about certain effects on net periodic benefit cost for the next 
fiscal  year  that  arise  from  delayed  recognition  of  the  gains  or  losses,  prior  service  costs  or 
credits, and transition asset or obligation. An employer with publicly traded equity securities is 
required to initially recognize the funded status of a defined benefit postretirement plan and to 
provide the required disclosures as of the end of the fiscal year ending after December 15, 2006.  

The  additional  adjustments  required  by  the  SFAS  158  has  been  made  after  the  accounting 
according to the SFAS 87 and SFAS 132. 

Although  the  adopted  accounting  standard  under  BR  CL  requires  the  Company  to  recognize 
pension  obligation  based  on  actuarial  methods  effective  January  1,  2002,  differences  under 
BR CL  related  to  the  prescribed  actuarial  methods,  date  of  first  adoption  and  amortization  of 
transition  obligations,  among  others,  as  compared  with  those  under  US  GAAP,  generate 
reconciling adjustments for US GAAP purposes.  

(i)  Pension plan (Plan G1) 

The  Company  sponsors  a  defined-benefit  plan  for  its  employees  (Plan  G1).  For  the 
purposes of calculating the funded status of Plan G1, the provisions of SFAS No. 87, were 
applied with effect from January 1, 1992, because it was not feasible to apply them from 
the effective date specified in the standard.  

(ii)  Supplementary pension plan (Plan G0) 

Pursuant  to  a  law  enacted  by  the  State  Government,  certain  employees  who  provided 
service  to  the  Company  prior  to  May  1974  and  retired  as  an  employee  of  the  Company 
acquired a legal right to receive supplemental pension payments (which rights are referred 
to as “Plan G0”). The Company pays these supplemental benefits on behalf of the State  

Government and makes claims for reimbursement from the State Government, which are 
recorded as accounts receivable, shareholder under BR CL. No expense is recognized for 
these benefits under BR CL. 

Consistent  with  the guidance  in  SEC  Staff  Accounting  Bulletin  Topic  5-T  ("SAB  No.  5-
T"), under US GAAP, the Company recognizes the costs and obligations associated with 
Plan G0 supplemental pension benefits incurred by the State Government on behalf of the 
Company  with  respect  to  its  employees  on  a  “push-down  basis,”  as  the  Company  is  the 
recipient  of  the  benefits  of  the  employee  service  for  which  the  supplemental  pension 
benefits  are  made.  These  benefits  are  accounted  for  in  accordance  with  SFAS  No.  87. 
Eventual  amounts  received  as  reimbursement  from  the  State  Government,  if  any,  are 
treated as additional paid-in-capital. 

Retained  earnings  was  reduced  in  the  first  year  of  presentation  (1998)  for  the  actuarial 
liability  computed  under  SFAS  No.  87.  and  the  balance  of  amounts  due  from  the  State

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Government for pensions paid was charged to income, as this amount relates to a charge 
for  past  services  rendered  by  the  Company’s  former  employees.  Amounts  reimbursed  to 
the Company by the State Government were accounted for as additional paid-in capital and 
a  reduction  of  the  actuarial  liability  to  reflect  gross  benefits  paid.  The  remaining  unpaid 
reimbursable  balance  due  from  the  State  Government  (effectively  a  subscription 
receivable) was charged off as a deduction to shareholders' equity. 

(iii)  Sabbatical paid leave 

The  Company  also  pays  amounts  equivalent  to  three  months  of  vacation  for  each  five 
years' of service as a form of sabbatical paid leave to certain of the Company’s employees 
for  which  it  also  claims  reimbursement  from  the  State  Government.  Consistent  with  the 
guidance  in  SAB  Topic  5-T,  under  US  GAAP  the  Company  recognizes  the  costs  and 
obligations  associated  with  these  sabbatical  leave  benefits  incurred  by  the  State 
Government  on  behalf  of  the  Company  with  respect  to  its  employees  on  a  “push-down 
basis,” as the Company is the recipient of the benefits of the employee service for which 
the  supplemental  pension  benefits  are  made.  The  Company  has  accounted  for  this 
sabbatical  expense  by  relieving  directly  against  retained  earnings  for  the  first  year 
presented and subsequently the Company recognized as a charge to income the receivable 
due  from  the  State  Government,  for  sabbatical  leave  paid,  as  this  amount  relates  to  a 
charge  for  past  services  rendered  by  the  Company’s  former/current  employees.  Amounts 
reimbursed by the State Government, if any, are accounted for as additional paid-in capital. 

During  the  year  ended  December  31,  2000,  in  the  financial  statements  prepared  in 
accordance with BR CL, sabbatical leave accruals totaling R$ 23,747, which had in prior 
years been charged to income, and were accounted for as a receivable (reimbursement) due 
from the State Government, were reversed, as the Company does not consider this to be an 
expense  under  BR  CL.  Similarly,  during  December  31,  2006,  2005  and  2004,  total 
amounts not accrued were R$ 1,991, R$ 968 and R$ 14,743, respectively. Such amounts, 
consistent  with  the  US  GAAP  difference  mentioned  above,  were  ‘pushed  down’  as 
expenses in the reconciliation to US GAAP.

expenses. Under US GAAP, APB 21 – “Interest on Receivables and Payables” debt issue costs 
are  deferred  and amortized using the effective interest  method  over the remaining  term  of  the 
applicable  debt  obligations.  At  December  31,  2006,  the  balance  of  deferred  debt  issue  costs 
included as an adjustment to shareholders’ equity, related to debt issue costs was R$ 11,331 (in 
2005 was R$ 13,976), net of accumulated amortization.

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

(k)  Donations  

Under  BR  CL  these  amounts,  which  comprise  principally  contributions of  property,  plant and 
equipment that we receive from third parties, were recorded at fair value, generally determined 
based on estimates of the current replacement cost of the assets contributed, as a revenue until 
December 31, 2003 an as a credit to other capital reserves after this date.  

For  U.S.  GAAP  purposes,  the  amounts  recorded  as  revenues  and  capital  reserves  related  to 
donations  received  from  third  parties  would  be  classified  as  a  deferred  credit,  recorded  as  a 
reduction  of  the  related  amount  of  property,  plant  and  equipment  in  the  balance  sheet,  and 
amortized  to reduce depreciation expense over the related estimated useful life of the  donated 
assets.  Prior to 2006, we did not account for any differences between BR CL and US GAAP, as 
the amounts of such donations have not historically been, and were not expected to be material. 
However,  in  light  of  the  cumulative  nature  of  such  donations,  beginning  January  1,  2006,  we 
began accounting for such differences.   

As a result, shareholders equity under U.S. GAAP was lower by R$ 69,535, net of tax effects, as 
compared to BR CL at December 31, 2006. Net income in 2006 was also lower by R$15,871, 
net  of  tax  effects,  as  compared  to  BR  CL,  as  a  result  of  the  cumulative  differences  in  the 
accounting for donations under  BR CL.  The related impacts on prior year results of operations 
were not material. 

(l)  Segment reporting 

Under BR CL, no separate segment reporting is required. 

Under  US  GAAP,  SFAS  No.  131,  "Disclosures  about  Segments  of  an  Enterprise  and  Related 
Information" establishes the standards for the manner in which public enterprises are required to 
report  financial  and  descriptive  information  about  their  operating  segments.  SFAS  No.  131 
defines  operating  segments  as  components  of  an  enterprise  for  which  separate  financial 
information is available and evaluated regularly as a means for assessing segment performance 
and allocating resources to segments. A measure of profit or loss, total assets and other related 
information are required to be disclosed for each operating segment. 

The Company operates in two segments: water services and sewage services. 

(m)  Comprehensive income 

BR CL does not embody the concept of comprehensive income. 

Under  US  GAAP,  the  Company  has  adopted  the  provisions  of  SFAS  No.  130,  "Reporting 
Comprehensive  Income."  A  foreign  (i.e.,  non-U.S.)  registrant  may  present  the  statement  of 
comprehensive income in any format permitted by SFAS No. 130. The information required by 
SFAS No. 130, has been included in the condensed financial statement information as prepared 
in accordance with US GAAP below. 

(n)  Provision for dividends and interest on shareholders' equity

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Under BR CL, at each annual balance sheet date management is required to propose a dividend 
distribution  from  earnings  and  accrue  for  this  in  the  financial  statements.  Under  BR  CL, 
companies  are  permitted  to  distribute  a  notional  amount  of  interest,  subject  to  certain 
limitations,  calculated  based  on  the  government  TJLP  interest  rate,  on  shareholders'  equity. 
Such  amounts  are  deductible  for  tax  purposes  and  are  presented  as  a  deduction  from 
shareholders'  equity.  Although  not  affecting  net  income  except  for  the  tax  benefit,  in  certain 
cases companies include this notional charge in interest expense and reverse the same amount 
before totaling net income. The Company presents the financial expense net of the reversal in its 
financial statements. 

Under  US  GAAP,  since  proposed  dividends  must  be  ratified  or  modified  at  the  annual 
shareholders' meeting, dividends would generally not be considered as declared at the balance 
sheet date and, as such, would not be accrued. However, because the State Government is the 
Company’s  controlling  shareholder, 
the  minimum  dividend  proposal  when  made  by 
management  at  year  end  is  maintained  as  a  provision,  and  therefore,  no  adjustments  has  been 
included  in  the  reconciliation  from  BR  CL  to  US  GAAP.  Interim  dividends  paid  or  interest 
credited  to  shareholders  as  interest  on  shareholders'  equity  under  BR  CL  is  considered  as 
declared  for  US  GAAP  purposes.  Under  US  GAAP,  no  similar  interest  distribution  concept 
exists. 

Distributions per share data (in the form of dividends or interest on shareholders’equity) is not 
required to be disclosed under BR CL. 

Interest on shareholders' equity per thousand common shares for the years ended December 31, 
2006, 2005 and 2004 were as follows:

Interest on shareholders' 
equity per shares 

(o)  Related parties 

Under BR CL, related parties are generally defined in a more limited manner and require fewer 
disclosures than US GAAP. The Company has expanded its disclosure for purposes of BR CL. 

No adjustments have been included in the reconciliation from BR CL to US GAAP. 

(p)  Items posted directly to shareholders' equity accounts 

Under  BR  CL,  various  items  are  posted  directly  to  shareholders'  equity  accounts.  Examples 
include  certain  capitalized  interest,  the  effects  of  adjustments  to  tax  rates  and  tax  incentive 
investment credits received. As noted in (a) above, Brazilian utility companies used to capitalize 
interest attributable to construction-in-progress at the rate of 12% per annum of the balance of 
construction-in-progress and that part which relates to interest on third-party loans is credited to 
interest  expense  based  on  actual  interest  costs  with  the  balance  relating  to  the  self-financed 
portion being credited to capital reserves.

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Under  US  GAAP,  such  items  relating  to  third-party  debt  would  be  posted  to  the  statement  of 
operations.  Since  the  original  posting  to  equity  accounts  would,  under  US  GAAP,  be  made 
directly  to  the  statement  of  operations,  these  adjustments  are  included  in  the  reconciliation  of 
shareholders' equity and net income determined in accordance with US GAAP. 

 (q)  Discounting 

Under BR CL, discounting of trade receivables and payables to present value is not permitted. 
Under  US  GAAP,  APB  No.  21  "Interest  on  Receivables  and  Payables",  such  discounting,  in 
certain cases, is required  to record the effects of implicit interest income or expense or which 
are  different  from  market  rates  on  long-term  assets  and  liabilities,  except  for  transactions  in 
which  interest  rates  are  affected  by  the  tax  attributes  or  legal  restrictions  prescribed  by  a 
government agency. The company does not have original long term agreements. 

No  adjustments  have  been  included  in  the  reconciliation  from  BR  CL  to  US  GAAP  as  the 
Company  had  no  long-term  trade  accounts  payables  or  receivables  potentially  subject  to 
discounting at December 31, 2006, 2005 and 2004. 

(r) Classification of statement of operations line items  

Under  BR  CL,  as  noted  above,  the  classification  of  certain  income  and  expense  items  is 
presented differently from US GAAP. The Company has recast its statement of operations under 
BR CL to present a condensed statement of operations prepared in accordance with US GAAP. 
The reclassifications are summarized as follows:  

(i)    Interest income and interest expense, together with other financial charges, are displayed 
within  operating  income  in  the  statement  of  operations  presented  in  accordance  with  BR 
CL.  Such  amounts  have  been  reclassified  to  non-operating  income  and  expenses  in  the 
condensed statement of operations prepared in accordance with US GAAP.  

(ii)      Under  BR  CL,  gains  and  losses  on  the  disposal  or  impairment  of  permanent  assets  are 
classified  as  non-operating  income  (expense).  Under  US  GAAP,  gains  and  losses  on  the 
disposal or impairment of property, plant and equipment are classified as an adjustment to 
operating income.  

(iii)  Following the issue of a new accounting standard under BR CL, effective January 1, 2002, 
the  Company  is  amortizing  the  related  transition  obligation  related  to  Plan  G1  over  five 
years. The related amortization, as permitted, is being presented as an “Extraordinary item” 
net  of  taxes,  in  the  statement  of  operations.  Under  US  GAAP,  this  amortization  expense 
would be included as part of operating income. 

(s) Earnings per share 

Under  BR  CL,  net  income  per  share  is  calculated  on  the  number  of  shares  outstanding  at  the 
balance sheet date. Information is disclosed per lot of one thousand shares, because this is the 
minimum number of shares of the Company that can be traded on the stock exchanges.

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Under US GAAP, in accordance with SFAS No.128, "Earnings per Share", the presentation of 
earnings  per  share  is  required  for  public  companies,  including  earnings  per  share  from 
continuing operations and net income per share on the face of the statement of operations, and 
the  per  share  effect  of  changes  in  accounting  principles,  discontinued  operations  and 
extraordinary  items  either  on  the  face  of  the  statement  of  operations  or  in  a  note.  A  dual 
presentation is required: basic and diluted. Computations of basic and diluted earnings per share 
data are based on the weighted average number of shares outstanding during the period and all 
potentially dilutive shares outstanding during each period presented, respectively. 

Statement 128 requires the retroactive restatement of earnings-per-share computations for stock 
dividends, stock splits, and reverse splits.  If a stock dividend or split is consummated after the 
close of the period but prior to the issuance of the financial statements, the earnings-per-share 
computation should be based on the new number of shares. 

The Board of Directors, in its meeting on March 30, 2007, approved the proposal for submission 
to the Annual Shareholders’ Meeting, which took place on April 30, 2007, of the Grouping of 
Shares. On June 4, 2007, the shares were grouped in the proportion of 125 (one hundred twenty 
five)  shares  to  1  (one)  share.  The  capital  stock  is  represented  by  227,836,623  common 
nominative  and  scriptural  shares,  without  par  value,  remaining  unchanged  Sabesp’s  capital 
stock. 

Simultaneously to the grouping operation, the American Depositary Receits (ADR’s) started to 
be traded in the proportion of 2 (two) shares to each ADR. 

Considering  the  grouping  of  shares  mentioned  above  the  weighted-average  number  of  shares 
used  in  computing  basic  earnings  per  share  for  December  31,  2006,  2005  and  2004  was 
227,836,623. The Company had no potentially dilutive shares outstanding during 2006, 2005 or 
2004. 

(t) Financial statement note disclosures  

BR  CL  requires,  in  general,  less  information  to  be  disclosed  in  the  notes  to  the  financial 
statements than US GAAP. The additional disclosures required by US GAAP which are relevant 
to these financial statements are included in this Note 23, 24 and 25.  

(u)  Leasing Transactions 

Under  Brazilian  GAAP,  generally,  lessees  account  for  long-term  leases  as  operating  leases, 
whereas  in  accordance  with  U.S.  GAAP  such  leases  could  be  accounted  for  as  operating  or 
capital  leases.  As  a  result,  under  Brazilian  GAAP,  lease  payments  by  lessees  with  respect  to 
leases  are  charged  as  an  expense  as  incurred.  Under  U.S.  GAAP,  the  lease  payments  may  be 
charged as an expense as incurred (operating leases) or the leased asset and the corresponding 
lease liability may be recognized in the balance sheet and the effect of depreciation and interest 
expense in the results of operations (capital leases).

Recently Issued Accounting Pronouncements 

The  Financial  Accounting  Standard  Board  (“FASB”)  has  issued  some  accounting  pronouncements  and 
interpretations,  but  neither  of  the  standards  or  interpretations  had  impacted  materially  the  Financial 
Statements of the company as described below: 

In  February  2006,  the  FASB  issued  Statement  No.  155,  “Accounting  for  Certain  Hybrid  Financial 
Instruments,” an amendment of FASB Statement No. 133 and 140 (“SFAS 155”), which permits fair value 
measurement  for  any  hybrid  financial  instrument  that  contains  an  embedded  derivative  that  otherwise 
would  require  bifurcation,  with  changes  in  fair  value  recognized  in  earnings.  The  fair-value  election  will 
eliminate  the  need  to  separately  recognize  certain  derivatives  embedded  in  hybrid  financial  instruments 
under FASB Statement No. 133,  “Accounting  for Derivative Instruments and Hedging Activities.” SFAS 
155 is effective  for all  financial instruments acquired or issued after the beginning of the  first  fiscal year 
that begins after September 15, 2006. The adoption of the pronouncement is not expected to have a material 
effect to SABESP financial statements. 

In  March  2006,  the  FASB  issued  SFAS  No.  156,  "Accounting  for  Servicing  of  Financial  Assets".  SFAS 
156  amends  SFAS  No.  140,  "Accounting  for  Transfers  and  Servicing  of  Financial  Assets  and 
Extinguishments  of  Liabilities",  which  establishes,  among  other  things,  the  accounting  for  all  separately 
recognized  servicing  assets  and  servicing  liabilities.  SFAS  156  amends  Statement  140  to  require  that  all 
separately  recognized  servicing  assets  and  servicing  liabilities  be  initially  measured  at  fair  value,  if 
practicable. SFAS 156 permits, but does not require, the subsequent measurement of separately recognized 
servicing assets and servicing liabilities at fair value. An entity that uses derivative instruments to mitigate 
the  risks  inherent  in  servicing  assets  and  servicing  liabilities  is  required  to  account  for  those  derivative 
instruments  at  fair  value. Under this  Statement,  an  entity  can  elect  subsequent  fair  value  measurement to 
account  for  its  separately  recognized  servicing  assets  and  servicing  liabilities.  An  entity  shall  adopt  this 
Statement as of the beginning of its first fiscal year that begins after September 15, 2006. Earlier adoption 
is permitted in certain cases. The impact of adopting this new rule is dependent on events that could occur

NOTES TO THE FINANCIAL STATEMENTS   
AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2006, 2005 AND 2004   
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

in  future  periods,  and  as  such,  an  estimate  of  the  impact  cannot  be  determined  until  the  event  occurs  in 
future periods. 

In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” An 
Interpretation  of  SFAS  No.  109,”  (“FIN  48”).  FIN  48  clarifies  the  accounting  for  uncertainty  in  income 
taxes recognized in an enterprise's financial statements in accordance with SFAS No. 109, “Accounting for 
Income Taxes.” FIN 48 requires that realization of an uncertain income tax position must be “more likely 
than  not”  (i.e.,  greater  than  50%  likelihood  of  receiving  a  benefit)  before  it  can  be  recognized  in  the 
financial statements. 

Further, this interpretation prescribes the benefit to be recorded in the financial statements as the amount 
most likely to be realized assuming a review by tax authorities having all relevant information and applying 
current  conventions.  Additionally,  FIN  48  provides  guidance  on  derecognition,  income  statement 
classification  of  interest  and  penalties,  accounting  in  interim  periods,  disclosure,  and  transition.  This 
interpretation  is  effective  for  fiscal  years  beginning  after  December  15,  2006.  SABESP  is  currently 
evaluating the effect the application of FIN 48 will have on its financial statements. 

In September 2006, the FASB issued Statement No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 
No.157  defines  fair  value,  establishes  a  framework  for  measuring  fair  value  in  generally  accepted 
accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 is effective 
for  financial  statements  issued  for  fiscal  years  beginning  after  November  15,  2007,  and  interim  periods 
within  those  fiscal  years.  The  transition  adjustment,  which  is  measured  as  the  difference  between  the 
carrying  amount  and  the  fair  value  of  those  financial  instruments  at  the  date  this  statement  is  initially 
applied, should be recognized as a cumulative effect adjustment to the opening balance of retained earnings 
for the fiscal year in which this statement is initially applied. SABESP is currently evaluating the effect the 
application of SFAS No. 157 will have on its financial statements. 

In  September  2006,  the  Securities  and  Exchange  Commission  ("SEC")  issued  Staff  Accounting  Bulletin 
108,  Considering  the  Effects  on  Prior  Year  Misstatements  when  Quantifying  Misstatements  in  Current 
Year  Financial  Statements  ("SAB  108").  SAB  108  requires  registrants  to  quantify  errors  using  both  the 
income  statement  method  (i.e.  iron  curtain  method)  and  the  rollover  method  and  requires  adjustment  if 
either  method  indicates a  material error. If  a correction in  the  current year  relating to  prior year  errors  is 
material to the current year, then the prior year financial information needs to be corrected. A correction to 
the  prior  year  results  that  are  not  material  to  those  years  would  not  require  a  restatement  process  where 
prior financials would be amended. SAB 108 is effective for fiscal years ending after November 15, 2006. 
The Company has assessed SAB 108 and has concluded that it did not have a material effect on its financial 
position, results of operations or cash flows. 

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension 
and Other Postretirement Plans an amendment of FASB Statements No. 87, 88, 106, and 132(R)”. 

The SFAS 158 requires an employer to recognize the overfunded or underfunded status of a defined benefit 
postretirement plan (other than a multi-employer plan) as an asset or liability in its statement of financial 
position  and  to  recognize  changes  in  that  funded  status  in  the  year  in  which  the  changes  occur  through 
comprehensive  income  of  a  business  entity  or  changes  in  unrestricted  net  assets  of  a  not-for-profit 
organization. This Statement also requires an employer to measure the funded status of a plan as of the date 
of its year-end statement of financial position, with limited exceptions. 

Another requirement of the statement is that the employer must disclose in the notes to financial statements 
additional  information about  certain  effects  on  net periodic  benefit cost  for the next  fiscal year  that  arise 
from  delayed  recognition  of  the  gains  or  losses,  prior  service  costs  or  credits,  and  transition  asset  or 
obligation. An employer with publicly traded equity securities is required to initially recognize the funded 
status of a defined benefit postretirement plan and to provide the required disclosures as of the end of the

fiscal  year  ending  after  December  15,  2006.  The  adoption  of  the  pronouncement  has  impacted  the 
SABESP‘s financial statements as presented on note 23. 

In  February  2007,  the  FASB  issued  SFAS  No.  159  which  provides  reporting  entities  an  option  to  report 
selected  financial  assets,  including  investment  securities  designated  as  available  for  sale,  and  liabilities, 
including  most  insurance  contracts,  at  fair  value.  SFAS  No.  159  establishes  presentation  and  disclosure 
requirements  designed  to  facilitate  comparisons  between  companies  that  choose  different  measurement 
attributes for similar types of assets and liabilities. The standard also requires additional information to aid 
financial statement users’ understanding of a reporting entity’s choice to use fair value on its earnings and 
also requires entities to display on the face of the balance sheet the fair value of those assets and liabilities 
for  which  the  reporting  entity  has  chosen  to  measure  at  fair  value.  SFAS  No.  159  is  effective  as  of  the 
beginning  of  a  reporting  entity’s  first  fiscal  year  beginning  after  November  15,  2007.  Early  adoption  is 
permitted as of the beginning of the previous fiscal year provided the entity makes that choice in the first 
120 days of that fiscal year and also elects to apply the provisions of SFAS No. 157. Because application of 
the standard is optional, any impacts are limited to those financial assets and liabilities to which SFAS No. 
159 would be applied, which has yet to be determined, as is any decision concerning the early adoption of 
the standard.

The date used to determine pension benefits was December 31, 2006. 

The amortization of the unrecognized liability at transition is over 16 years commencing 
on January 1, 1990.  

The expected long-term rate of return on plan assets was determined based on the weighted 
average estimated return of the plan assets, which includes equity securities, real state, 
loans and fixed income, based on information obtained from “SABESPREV”. This 
projected long-term rate includes the projected long-term inflation rate and takes into 
consideration such factors as projected future interest yield curves and economic 
projections available in the market. 

The plan’s investment policies and strategies are aimed to reduce investment risk through 
diversification, considering such factors as the liquidity needs and funded status of plan

(ii)  Law 11.445/07 

On January 5, 2007, Law No. 11,445 was enacted to regulate the basic sanitation industry in Brazil.  This 
law is in its initial stage of implementation and we cannot anticipate the effects that it will have on our 
operations  and  business.    There  are  several  uncertainties  related  to  the  new  legislation,  mainly  with 
respect to the creation of the regulatory authority for the basic sanitation industry and the tariff adjustment 
formula and structure that will be used for new concession contracts that we enter into under the new law, 
which could have a material adverse effect on us.

SEGMENT INFORMATION  

The  Company  has  two  identifiable  reportable  segments:  (i)  water  supply  systems;  and  (ii)  sewage 
collection systems. The chief operating decision maker uses these two segments to analyse the Company 
and uses income from operations before financial expenses, net as a measure of segment profit or loss. 

Total assets by segment is not readily available, and therefore not regularly provided to, nor reviewed by 
the Company’s chief operating decision maker. However, total property, plant and equipment by segment 
is  readily  available  and  reviewed  regularly  by  the  Company’s  chief  operating  decision  maker  to  make 
decisions  about  resource  allocations  and  to  measure  performance.  As  such,  management  believes  that 
total property, plant and equipment is a relevant measure for its operating segments and is disclosed by 
segment in Note 8.

27. SUBSEQUENT EVENT 

Program Contract with the Municipality of Lins. 

Federal Law nr. 11,107 of April 2006 created the “Program Contract” as the legal instrument to the set up of 
obligations related to the transfer of public services between the entities of the Federation. This new juridical 
model  is  called  associated  management.  The  cooperation  agreement  is  the  juridical  instrument  able  to 
discipline  the  associated  management  of  public  services,  according  to  the  provisions  of  article  241  of  the 
Federal Constitution. 

Thus, authorized by the cooperation agreement between the municipality of Lins and the State of São Paulo, 
Sabesp formalized, in January 26, 2007, the program contract with this municipality, which objective is the 
provision of services of water supply and sanitary sewage for 30 years, being extendable for an equal period. 
By the agreement, it is attributable to the State of São Paulo, through the Secretary of Sanitation and Energy, 
to  establish  the  targets  and  define  the  basic  sanitation  policy  in  the  State  of  São  Paulo,  incorporating  the 
specific targets expected for the Municipality. The compensation system of the services will be by means of 
tariff,  to  be  set  up  by  the  Municipality  and  it  shall  be  revised,  when  necessary,  to  insure  the  economic-
financial balance of the contract. 

All  assets  and  rights  pre-existing  to  the  contract  as  well  as  those  acquired  during  its  term  integrate  the 
services of water supply and sanitary sewage. The pre-existing amounts invested by Sabesp referring to the 
assets reversible by force of the concession contract terminated in 2005 remain as its property and they shall 
be  indemnified  by  the  municipality,  in  case  of  extinction  of  the  present  contract,  when  the  assets  will  be 
transferred to the municipality and, then, the amount of indemnification, at the time of extinction, shall be set 
up.  The  new  reversible  assets  shall  be  amortized  within  the  period  of  the  contract  and  they  shall  be 
indemnified by the municipality to Sabesp, in case of the extinction of the contract before it matures. 

Grouping of Shares  

The  Board  of  Directors’,  in  its  meeting  on  March  30,  2007,  approved  the  proposal  for  submission  to  the 
Annual Shareholders’ Meeting, to take place on April 30, 2007, the Grouping of Shares. On June 4, 2007, 
the  shares  were  grouped  in  the  proportion  of  125  (one  hundred  twenty  five)  shares  to  1  (one)  share.  The 
capital  stock  is  represented  by  227,836,623  common  nominative  and  scriptural  shares,  without  par  value, 
remaining unchanged Sabesp’s capital stock. 
Simultaneously to the grouping operation, the American Depositary Receits (ADR’s) started to be traded in 
the proportion of 2 (two) shares to each ADR. 

28. RESTATEMENT OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS  

Cash and cash equivalents 

Subsequent to the issuance of the financial statements for the year ended December 31, 2005, management 
determined that certain investments included in exclusive investment funds that were previously classified as 
cash  equivalents  under  Brazilian  GAAP  should  not  have  been  classified  as  cash  equivalents  under  US

in Note 23 have been restated to correct this classification. These reclassifications had no impact on

EXHIBIT 15.1 

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING 

The  management  of  Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo  –  Sabesp,  is  responsible  for 
establishing  and  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the 
effectiveness  of  internal  control  over  financial  reporting  as  defined  in  Rules  13a-15  (f)  under  the  U.S.  Securities 
Exchange Act of 1934. 

The  Company’s  internal  control  over  financial  reporting  is  a  process  designed  by,  or  under  the  supervision  of,  the 
Company’s  Chief  Executive  Officer  and  Chief  Financial  Officer  and  Investor  Relations  Officer,  and  effected  by  the 
Company’s  board  of  directors,  audit  committee,  management,  and  other  personnel  to  provide  reasonable  assurance 
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in 
accordance  with  generally  accepted  accounting  principles.  The  Company’s  internal  control  over  financial  reporting 
includes  those  policies  and  procedures  that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail, 
accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  Company;  (2)  provide  reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with 
generally accepted  accounting principles, and that  receipts  and  expenditures of  the Company  are being  made only  in 
accordance  with  authorizations  of  management  and  directors  of  the  Company;  and  (3)  provide  reasonable  assurance 
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that 
could have a material effect on the financial statements. 

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  material 
misstatements on a timely basis.  Therefore even those systems determined to be effective can provide only reasonable 
assurance  with  respect  to  financial  statement  preparation  and  presentation.   Also,  projections  of  any  evaluation  of 
effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Management  of  the  Company,  under  the  supervision  and  with  the  participation  of  our  Chief  Executive  Officer  and 
Chief  Financial  Officer  and  Investor  Relations  Officer,  assessed  the  effectiveness  of  the  Company’s  internal  control 
over  financial  reporting  as  of  December  31,  2006,  based  on  the  criteria  established  in  Internal  Control  –  Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission– COSO.   

A material weakness is a control deficiency, or a combination of control deficiencies, that results in more than a remote 
likelihood  that  a  material  misstatement  of  the  financial  statements  will  not  be  prevented  or  detected.    During 
management’s  assessment  of  the  Company’s  internal  control  over  financial  reporting  described  above,  management 
identified the following material weaknesses in internal control over financial reporting as of December 31, 2006: 

1.  Ineffective  controls  related  to  the  reconciliation  and  monitoring  of  the  balance  of  the  Unidentified 
Collections  (Unapplied  Cash  Receipts)  account,  included  as  part  of    Customer  Accounts  Receivable.    As  a 
result of this control deficiency, the Company identified the need to adjust the balance of this account in the 
amount of R$93,758 thousand for the year ended December 31, 2006.   

2. Ineffective controls to ensure the timely and accurate transfer of amounts from the construction-in-progress 
account to the corresponding accounts for property, plant and equipment, as well the timely commencement of 
recorded depreciation expense associated with capital assets placed in service.  This control deficiency resulted 
in audit adjustments to the financial statements for the year ended December 31, 2006.   

Because  of  the  material  weaknesses  described  above,  management  concluded  that  as  of  December  31,  2006,  the 
Company  did  not  maintain  effective  internal  control  over  financial  reporting  based  on  the  criteria  established  in 
“Internal Control – Integrated Framework” issued by COSO.   

 
 
     
  
 
Management’s  assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of 
December  31,  2006  has  been  audited  by  Deloitte  Touche  Tohmatsu  Auditores  Independentes,  the  Company’s 
independent registered public accounting firm, whose report is included herein.
