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$2.3407 to US$1.00, the commercial selling rate on December 31, 2005 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. Key Information—Exchange Rates” 
for information regarding exchange rates allocable to the Brazilian currency since January 1, 2001. 

Our audited  financial  statements  as of  December 31, 2004 and 2005 and  for the years  ended December 31,  2003, 
2004 and 2005 are included in this annual report.  The financial statements as of and for the years ended December 
31,  2003,  2004  and  2005  have  been  audited  by  Deloitte  Touche  Tohmatsu  Auditores  Independentes,  São  Paulo, 
Brazil.  The selected financial data as of December 31, 2001 and 2002 and the two years ending on December 31, 
2002 is derived from our financial statements audited by PricewaterhouseCoopers Auditores Independentes included 
in previously filed annual reports.  

Our audited financial statements are presented in reais and are prepared in accordance with Corporate Law Method, 
which are based on the Brazilian corporation law (Law No. 6,404/76, as amended), the rules and regulations issued 
by  the  Comissão  de  Valores  Mobiliários  (CVM),  or  the  Brazilian  securities  commission,  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 “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 Corporate Law Method with a reconciliation to generally 
accepted  accounting  principles  in  the  United  States  of  America  (“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 
Corporate Law Method. 

The  Corporate  Law  Method  differs  in  significant  respects  from  U.S.  GAAP.    Note  22  to  our  audited  financial 
statements  provides  a  description  of  the  differences  between  the  Corporate  Law  Method  and  U.S.  GAAP  as  they 
relate to our financial statements and a reconciliation from the 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  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. 

We do not have any subsidiaries. 

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

(1) 
(2)  The extraordinary item charged to income in the years ended December 31, 2003, 2004 and 2005 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  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 audited financial statements. 

(4)  Based upon the audited statements of cash flows for the years ended December 31, 2004, 2003 and 2002 included in note 24 to our audited 
financial statements and the audited statement of cash flows for the years ended December 31, 2000 and 2001 which are not included in this 
annual report. 

(5)  Adjusted EBITDA means net income (loss) before financial expenses, net, income tax and social contribution tax (a federal tax on income), 
depreciation and amortization, non-operating income (expenses), net and extraordinary item, net of income tax and social contribution tax.  
Adjusted  EBITDA  is  a  non-accounting  measurement  which  is  parallel  to  the  conventional  measurements  contained  in  the  Financial 
Statements  prepared  according  to  the  Corporate  Law  Method,  does  not  represent  cash  flow  for  the  periods  presented  and  should  not  be 
considered  as  an  alternative  to  net  income  (loss),  as  an  indicator  of  our  operating  performance  or  as  an  alternative  to  cash  flows  as  an 
indicator of liquidity.  Our definition of Adjusted EBITDA may not be comparable with EBITDA as defined by other companies.  Although 
Adjusted  EBITDA,  as  defined  above,  does  not  provide  a  measurement  of  operating  performance  as  accepted  under  the  Corporate  Law 
Method,  our  management  uses  it  to  measure  our  operating  performance  and  it  is  commonly  used  by  financial  analysts  in  evaluating  our 
business.  Adjusted EBITDA is calculated as follows:

by us to customers divided by (b) the total amount of water produced (after excluding certain non-physical water losses set out below) by 
us.  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

Exchange Rates 

Before  March  14,  2005,  there  were  two  principal  legal  foreign  exchange  markets  in  Brazil,  in  which  rates  were 
freely negotiated but could be strongly influenced by Central Bank intervention: 

• 

• 

the  commercial  rate  exchange  market,  dedicated  principally  to  trade  and  financial  foreign 
exchange transactions such as the buying and selling of registered investments by foreign entities, 
the purchase or sale of shares or the payment of dividends or interest with respect to shares; and 

the  floating exchange  market that was generally used for transactions not conducted through the 
commercial foreign exchange market. 

On March 4, 2005, the National Monetary Council enacted Resolution No. 3,265, pursuant to which the commercial 
rate exchange market and the floating rate exchange market were unified in a sole exchange market, effective as of 
March 14, 2005.   The new  regulation  allows,  subject to certain procedures and specific regulatory provisions, the 
purchase  and  sale  of  foreign  currency  and  the  international  transfer  of  reais  by  a  person  or  legal  entity,  without 
limitation with respect to the amount involved, provided, however, the transaction is legal.  However, the underlying 
transaction  must  have  been  valid.    Foreign  currencies  may  only  be  purchased  through  financial  institutions 
domiciled in Brazil authorized to operate in the exchange market. 

Following  the  introduction  of  the  real  in  1994  and  through  1998,  the  Central  Bank  maintained  a  band  system 
exchange  rate,  under  which  the  exchange  rate  between  the  real  and  the  U.S.  dollar  would  fluctuate  within  a  pre-
established  moving  band.   In  January 1999, due to  market pressures,  the Central Bank  abolished the  band system 
and allowed the real/U.S. dollar exchange rate to float freely.  Since then, the exchange rate has been established by 
the market and has fluctuated considerably, reporting a maximum quotation of R$3.955 per U.S.$1.00 on October 
22,  2002.    Since  the  liberalization  of  the  exchange  rate,  the  Central  Bank  has  intervened  occasionally  to  control 
unstable  movements  in  the  foreign  exchange  rate.    It  is  not  possible  to  predict  whether  the  Central  Bank  will 
continue to let the real float freely or whether the real will remain at its present level.  Accordingly, it is not possible 
to predict what impact the Brazilian government’s exchange rate policies may have on us. 

The  following  table  shows  the  commercial  selling  rate  for  U.S.  dollars  for  the  periods  and  dates  indicated.    The 
information in the “Average” column represents the average of the exchange rates for the period indicated.

Risk Factors 

Risks Relating to our Control by the State of São Paulo 

We are controlled by the State, whose interests may be contrary to the interests of holders of our shares or ADSs. 

The State of São Paulo, which we refer to as the State, through its ownership of our common shares, has the ability 
to control the election of a majority of the  members of our Conselho de Administração (“Board of Directors”), to 
appoint  our  senior  management  and  to  determine  our  operations  and  strategy.    The  State  owned  50.3%  of  our 
outstanding  common  shares  as  of  March  31,  2006  and  50.3%  of  our  outstanding  common  shares  as  of 
December 31, 2005. 

The State has from time to time in the past used, and may in the future use, its controlling interest in our company to 
direct that we engage in certain business activities and  make certain expenditures which are designed primarily to 
promote the political, economic or social goals of the State and not necessarily to enhance our business and results 
of operations.  As a result, actions taken by the State in relation to Sabesp could be contrary to the interests of the 
holders of our shares or ADSs. 

Most of our Board of Directors and senior management are political appointees of the Governor of the State, who 
are subject to periodic change unrelated to our business needs. 

Newly-elected  Governors  of  the  State  typically  make  significant  changes  in  our  Board  of  Directors  and  senior 
management and, historically, the Chairman of our Boargd of Directors has been the Secretary of the Energy, Water 
Resources  and  Sanitation  Secretariat  of  the  State.    In  2002,  new  senior  officials  were  appointed  for  the  state 
government administration, including Mr. Mauro Guilherme Jardim Arce as the new Secretary of the Energy, Water 
Resources and Sanitation Secretariat of the State.  Mr. Arce was also elected as Chairman of our Board of Directors.  
On October 2006, there will be elections for the State government.  Changes in government or government policy 
could lead to changes in our senior management which in turn could have a material adverse effect on our business 
strategy, cash flows, results of operations, financial condition or prospects. 

We  have  accounts  receivable  owed  by  the  State  and  some  State  entities,  as  well  as  a  substantial  amount  of 
negotiated long-term receivables owed by the State, and we cannot assure you as to when or whether the State 
will pay amounts owed to 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, 2005, 
the amounts owed to us by the State for the provision of water and sewage services included R$182.7 million, which 
was  considered  overdue  as  of  February  29,  2004.    As  of  December  31,  2005,  the  State  owed  us  an  additional 
R$111.5 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$672.7 million  as  of  December  31,  2005  (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, as discussed below).  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.   

In September 1997, December 2001 and March 2004, we entered into agreements with the State to settle overdue 
amounts payable to us.  Under the terms of these agreements, the amounts may be settled through the application of 
dividends payable by us to the State and by the transfer to us of certain reservoirs in the Alto Tietê System which we 
use,  but  which  are  owned  by  the  State.    However,  the  agreements  do  not  require  the  State  to  apply  all  dividends 
payable by us to them to the repayment of amounts owed to us.  Since the State entered into these agreements it has 
applied the dividend received from us to the repayment of amounts it owes to us.   

Under the December 2001 agreement, we converted a substantial amount of overdue accounts receivable due from 
the  State  and  some  State  entities  into  long-term  accounts  receivable.    According  to  the  March  2004  agreement, 

8 

 
which  amended  the  December  2001  agreement,  the  State  recognized  a  debt  with  us  in  the  amount  of 
R$581.8 million regarding unpaid receivables up to February 29, 2004 and we recognized an amount owed to the 
State as dividends declared in the form of interest on shareholders’ equity totaling R$518.7 million. 

We  cannot  assure  you  as  to  when  or  if  the  State  will  pay  overdue  amounts  due  to  us  by  it  and  by  some  State-
controlled  entities.    Furthermore,  due  to  the  State’s  history  of  not  making  timely  payments  to  us  in  respect  of 
services provided by us and of not reimbursing us in a timely manner for the State-mandated special retirement and 
pension payments, 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.  If the State does not pay the amounts it owes us, our cash 
flows, results of operations and financial condition will be adversely affected. 

We expect that a portion of long-term accounts payable by the State to us will be settled by the transfer to us of 
State-owned  reservoirs  in  the  Alto  Tietê  System,  but  we  cannot  assure  you  of  the  value  to  be  given  to  these 
reservoirs or of the timing or legality of these transfers. 

Under the terms of the December 2001 agreement referred to above, the State agreed to transfer the reservoirs in the 
Alto Tietê System to us in exchange for the cancellation of a portion of the accounts receivable due from the State 
and of reimbursements due from the State for State-mandated special pension payments we have made.  Under the 
terms  of  the  agreement,  the  value  of  these  reservoirs  should  be  determined  by  an  appraisal  process  prior  to  their 
transfer and amounts owed to us from the State are subject to an audit by a State-appointed auditor. 

In July and August 2002, a State-owned construction company, on behalf of the State, and an independent appraisal 
firm,  on  our  behalf,  presented  their  valuation  reports  relating  to  the  reservoirs.    The  appraisals  contained  in  these 
reports  were  in  the  amounts  of  R$335.8 million  and  R$341.2 million,  respectively.    Under  the  terms  of  the 
December  2001  agreement,  the  arithmetic  average  of  these  appraisals  will  be  deemed  to  be  the  fair  value  of  the 
reservoirs.    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.  However, a final determination as to the fair value of these reservoirs is still 
pending and we cannot assure you as to when the reimbursement of the pension payments will take place. 

In addition, 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  us  of  ownership  of  the  Alto  Tietê  System 
reservoirs from the State Department of Water and Energy of the State would be illegal.  In October 2004, the court 
ruled in favor of the Public Attorney of the State.  In response, we filed an appeal, which is pending final decision 
and the State successfully filed an action suspending the lower court’s decisions until final judgment is reached by 
the  Court  of  Appeals  of  the  state  of  São  Paulo  (Tribunal  de  Justiça  do  Estado  de  São  Paulo).    We  are  unable  to 
predict whether we will succeed in appealing such decision and cannot assure you as to whether the transfer of these 
reservoirs will occur.   

The State has agreed to reimburse us for pension benefits owed to us; however, if agreement is not reached with 
respect to the amounts of these reimbursements or if the State delays in making these payments, our cash flows, 
results of operations and financial condition could be adversely affected. 

The December 2001 agreement also provided that the State’s legal advisors 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.    The  commencement  of  reimbursement 
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 in the 
Alto Tietê System 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.  Under the December 2001 agreement, 
the original first payment was to be made in July 2002. Negotiations are still ongoing between the Company 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 have retained Fundação 

9 

 
Instituto de Pesquisas Contábeis, Atuarías e financeras (“FIPECAFI”) to validate the actual values to be reimbursed 
by  the  State,  in  accordance  with  the  opinions  provided  by  the  Office  of  the  State  Attorney  General.    We  cannot 
assure  you  as  to  when  agreement  among  the  parties  will  be  reached  or  when  the  State  will  commence  making 
payments in respect of these amounts.  If an agreement among the parties is not reached or if the State delays or fails 
to make such payments, our cash flows, results of operations and financial condition could be adversely affected. 

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  fees  to  the  owner  in  the  form  of  rent  and  additional  operational  and 
maintenance expenses with respect to our use of such reservoirs. 

In connection with the provision of water services, we use the Billings and Guarapiranga reservoirs that are owned 
by a State-controlled company.  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 in the future we will continue to be able to use the reservoirs without paying a fee, 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 fees 
to the owner or additional maintenance or operational costs for these properties, our cash flows, results of operations 
and financial condition could be adversely affected. 

Risks Relating to Our Business 

The basic sanitation sector is not specifically regulated in Brazil and the approval of any proposed regulations for 
the water and sewage industry may negatively affect our operations. 

There  is  not,  at  the  present  time,  any  specific  regulation  in  connection  with  sanitation  services  in  Brazil. 
Accordingly, the Brazilian Federal Congress has, from time to time, discussed proposals for regulation, which would 
establish directives for basic sanitation services.   

Currently, several bills are under debate at the Brazilian Federal Congress and at the Brazilian Senate.  Both Houses 
of Representatives have agreed upon the creation of a joint committee (comissão mista) that will be responsible for 
the  organization  and  systemization  of  the  proposed  regulation  for  water  and  sewage  services  in  Brazil.    Any 
proposed  regulation,  when  and  if  approved,  could  establish  a  new  municipal  regulatory  authority  for  our  industry 
that  may,  in  part,  preempt  the  existing  State  regulatory  authorities  under  which  we  operate  in  the  Metropolitan 
Region.  In this respect, there are currently two legal proceedings being reviewed by the Brazilian Supreme Court 
(Supremo  Tribunal  Federal)  challenging  the  constitutionality  of  two  state  laws  that  provide  for  the  creation  of 
metropolitan  regions  and  seeking  the  declaration  of  the  state  as  the  regulatory  authority  for  water  and  sewage 
services within such regions.  Although the results of these proceedings may not directly impact the bills currently in 
debate at the House of Representatives, they will set relevant precedents in connection with the establishment of the 
regulatory authority for metropolitan regions.  In addition, a new regulation could modify the way we charge for our 
water and sewage services businesses, as well as our capital expenditure program.  Any of these changes could have 
an adverse effect on our revenue, by causing us to lose concessions we currently hold, or on our operating margins, 
by limiting our ability to pass our cost on to our customers. 

As of the date of this annual report, no proposed federal regulation for the water and sewage industry has been voted 
on  by  the  Brazilian  Federal  Congress.    We  cannot  anticipate  if,  when  or  in  which  terms  any  proposed  federal 
regulation  will  become  effective.    Any  of  the  proposed  new  regulations,  if  approved  by  the  Brazilian  Federal 
Congress, could have a negative effect on our operations in the São Paulo Metropolitan Region, as well as in other 
areas that we serve.   

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. 

Governmental water agencies of the State and the Federal Government are authorized to collect fees from entities, 
including  us,  that  either  abstract  water  from,  or  dump  sewage  into,  water  resources  controlled  by  these  agencies.  

10 

 
The fees collected by these agencies are to 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 fees 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 Jundiai River 
Basin.    Given  that  the  tariff  readjustment  formula  currently  approved  by  our  Board  of  Directors  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 fees that may be assessed in connection with the abstraction of water or 
the dumping of sewage to other water resources that we use, or whether we will be able to continue to pass on the 
cost of all of these fees to our customers. 

We  have  accounts  receivable  due  from  municipalities  and  we  cannot  assure  you  as  to  when  or  whether  these 
municipalities will pay us. 

As  of  December  31,  2005,  we  had  accounts  receivable  totaling  R$727.9 million  from  municipalities  to  which  we 
provide  water  on  a  wholesale  basis.    Of  this  amount,  R$78.9 million  was  91  to  360  days  overdue  and 
R$588.7 million  was  more  than  360  days  overdue.    In  some  cases,  the  Brazilian  courts  have  required  that  we 
continue to provide water on a wholesale basis to municipalities, even if they fail to pay our invoices.  Additionally, 
as  of  December  31,  2005,  we  had  accounts  receivable  in  the  amount  of  R$377.4 million,  owed  to  us  by 
municipalities to which we render water and sewage services, including R$300.6 million owed by the Municipality 
of the City of São Paulo. 

Although  we  have  entered  into  negotiations  with  municipalities  to  reschedule  such  accounts  receivable  and  have 
also filed legal proceedings against municipalities to collect the overdue amounts, some municipalities are currently 
not  paying  our  invoices  in  full  or  on  a  timely  basis.    In  addition,  some  governmental  entities  located  in 
municipalities we serve are also not paying us on a regular basis.  We cannot assure you as to whether or when these 
municipalities will resume making regular payments or pay overdue amounts owing to us.  If these municipalities 
and  government  agencies  do  not  pay  amounts  they  owe  us,  our  cash  flows,  results  of  operations  and  financial 
condition will be adversely affected. 

We do not hold formal concessions for 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. 

We do not hold formal concessions in the City of São Paulo, which on December 31, 2005 accounted for 56.8% of 
our  sales  and  services  rendered,  or  in  40  other  municipalities  in  the  state  of  São  Paulo.    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 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.  
The  City  of  São  Paulo  legislature  approved  Law  13,670  of  November  25,  2003  through  which  it  intended  to 
establish  the  authority  to  regulate  its  public  water  supply  and  sewage  services.    Following  the  enactment  of  Law 
No. 13,670,  the  Governor  of  the  State  filed  a  legal  action  alleging  that  the  law  is  unconstitutional,  as  a  result  of 
which the enforcement of Law No. 13,670 has been suspended.  On April 20, 2005, the court ruled in favour of the 
Governor of the State, by a majority of votes.  The City of São Paulo appealed the decision and a trial judgement 
was still pending as of the date of this annual report.  We cannot assure you when or if the suspension of Law 13,670 

11 

 
will end, and we cannot anticipate the effect of its renewed application which could result in the creation of different 
conditions as compared to those under which our services are currently provided in the City of São Paulo. 

Municipalities for which we hold concessions may choose not to renew their concessions to us. 

We provide water and sewage services in 325 municipalities pursuant to concessions granted by the municipalities.  
Substantially all of these concessions have 30-year terms. As of December 2005, 17 of our concessions had expired; 
256 are due to expire between 2006 and 2010, of which 127 are scheduled to expire during 2006 and 30 in 2007. All 
other concessions will expire between 2011 and 2034. 

Some of the expired concession agreements have been extended for a short term while we negotiate the terms and 
conditions of a final agreement with each relevant municipality.  The new agreements may be executed under a new 
regime provided for by a newly enacted law which establishes principles to be observed when public consortiums 
contract  with  the  municipalities,  with  the  objective  of  allowing  the  provision  of  public  services  to  be  jointly 
managed.    Despite  the  expiration  of  the  agreements,  we  continue  to  provide  water  and  sewage  services  to  all  17 
municipalities. If certain municipalities choose not to renew their concessions, it could adversely affect our results of 
operations and financial condition. Even if they choose to renew these concessions, we cannot assure you that we 
will obtain the same terms that we currently have. 

Municipalities  may  terminate  our  concessions  for  any  “good  public  reason”  or  if  we  fail  to  meet  our 
contractual obligations. 

Municipalities  may  terminate  our  concessions  under  some  circumstances,  including  if  we  fail  to  comply  with  our 
obligations  under  the  relevant  concession  contracts  and  applicable  law.    In  addition  to  contractual  termination 
provisions  in  concession  contracts,  municipalities  have  the  inherent  power  under  Brazilian  law  to  terminate 
concessions prior to their contractual expiration dates for any “good public reason”.  The meaning of “good public 
reason” has not been defined by Brazilian law or conclusively determined by Brazilian courts.  In the event of the 
termination  of  a concession,  we  may receive inadequate  compensation  from the concessionaire  municipality.   We 
may also incur material litigation costs related to termination of concessions and compensation.  The Constitution of 
the State establishes that the municipalities in which we operate as water and sewage service providers may, in the 
course of granting authority over these services, create their own autonomous entities to render such services in their 
territories instead of continuing to use our services, with  the obligation to indemnify us for the termination of the 
concession  with  us  over  a  term  of  up  to  25  years  rather  than  at  the  time  the  concession  is  terminated.    The  State 
obtained an injunction in a legal action alleging the 25-year term to be unconstitutional.  As a result, the maximum 
term for payment of the indemnification has been suspended.  In the event that this injunction is stayed and/or the 
outcome of the legal action is not favorable to us, the indemnification over a term of 25 years may adversely affect 
our operational results and financial condition.  In 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 Appeals of the State, which 
ordered the action to be carried forward and 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.    The  municipality  and  the  house  of 
representatives  of  Santos  have  filed  an  appeal,  and  we  cannot  assure  you  that  the  ultimate  determination  will  be 
favorable to us.  Despite the pending lawsuit, we continue to provide water and sewage services to Santos. 

We cannot assure you that other municipalities will not seek to terminate their concessions.  Exercise of concession 
termination rights by substantial numbers of municipalities could have a material adverse effect on our cash flows, 
results of operations and financial condition. 

We  may  be  required  to  compete  through  a  public  bidding  process  in  order  to  obtain  new  or  renew 
existing concessions. 

Substantially all of our concessions were granted without a public bidding process.  Under current Brazilian Federal 
and State law, however, for any new concession we may be required to participate in a bidding process.  In addition, 
if a public entity from which we hold a concession granted prior to the enactment of the concession laws determines 
that in order to comply with such laws it must engage in a public bidding process, we could be required to compete 

12 

 
in order to renew our existing concession.  While we may be able to obtain concessions without participating in a 
bidding  process,  we  cannot  assure  you  that  the  Brazilian  courts  will  continue  to  interpret  the  concessions  laws  to 
permit municipalities to grant concessions without a public bidding process or that we will be able to secure all new 
water and sewage concessions that we may wish to obtain. 

In the event we are obligated to participate in public bidding processes in order to renew our existing concessions or 
to obtain new ones, our failure to outbid our competitors for our existing concessions may adversely impact our cash 
flows, results of operations and financial condition. 

We  may  be  unable  to  increase  customer  tariffs  in  line  with  increases  in  inflation  and  operating  expenses, 
including taxes. 

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, this power 
is, in practice, subject to political and legal constraints.  From mid-1999 until mid-2001 we did not raise our tariffs, 
due to a State policy of not increasing tariffs for 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%.  A new readjustment formula was approved by our Board 
of Directors and has been applied to the  tariff adjustment since August 2003.  Using this new formula, 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%.    Because  that  increase  was  much  higher  than  the  accumulated  inflation  levels  for  the 
corresponding period, we decided to adjust the tariff by 9.0%, effective August 31, 2005.  The remaining percentage 
(1.94%)  was  deferred  to  the  2006  tariff  adjustment.    Tariffs  with  respect  to  the  residential  social  (which  includes 
residences of low-income families that live in sub-standard conditions, residences of persons unemployed for up to 
12 months and collective living residences) and favela (shantytown) categories, are not always increased at the same 
rate as other tariffs.  For example, in August 2003, these tariffs were increased by only 9.0% and were not set using 
the  new  formula.    However,  in  August  2004  and  August  2005,  the  tariffs  with  respect  to  the  residential  social 
categories  were  increased  by  the  same  percentage  as  the  other  catogories,  6.8%  and  9.0%  respectively.      We  will 
continue to rely upon tariff revenue to provide funds for our capital expenditure program in addition to our financing 
activities  and  to  meet  our  debt  service  requirements.    We  are  currently  conducting  studies  with  a  view  to 
implementation of a new tariff policy.  Such studies have been delivered to our executive committee and board of 
directors and the recommendations resulting thereof are currently being detailed for implementation.  However, we 
cannot  assure  you  when  and  if  a  new  tariff  policy  will  be  implemented  or  if  such  implementation  will  meet  our 
expectations.  Any failure to establish or maintain tariffs commensurate with these and our other needs could have 
an adverse effect on our cash flows, results of operations and financial condition. 

Our  capital  expenditure  program  requires  substantial  liquidity  and  capital  resource,  and  any  failure  to  obtain 
new financing may have a material adverse effect on the operation and development of our business. 

Our  capital  expenditure  program  calls  for  expenditures  of  approximately  R$4.8  billion  in  the  period  from  2006 
through 2010, including approximately R$960.0 million in 2006 and R$960.0 million in 2007.  We spent R$678.2 
million on our capital expenditure program in 2005.  

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.  In this way, a significant portion of 
our financing needs has been funded by financing provided by lenders controlled by the Federal Government.  For 
example, we are currently negotiating with the Brazilian Economic and Social Development Bank (Banco Nacional 
de  Desenvolvimento  Econômico  e  Social,  or  “BNDES”),  and  Caixa  Econômica  Federal  (a  bank  owned  by  the 
Brazilian government) for additional loans to finance portions of our capital expenditure program.  We also benefit 
from long-term financing from domestic and 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 finance our capital expenditure 
program. 

13 

 
We cannot assure you that we will be able to obtain sufficient funds to complete our capital expenditure program .  
Failure to obtain the requisite funds could delay or prevent completion of our capital expenditure program and other 
projects, which may have a material adverse effect on the operation and development of our business. 

Brazilian regulations as well as contractual provisions may limit our ability to incur indebtedness in the future. 

Because we are controlled by the State we are subject to special credit rules for the public sector published by the 
Brazilian monetary authorities.  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 
such  entities’  net  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 bonds in both the domestic 
and international capital markets and other publicly traded obligations.  These limitations on obtaining credit could 
adversely  affect  the  development  of  our  business,  our  ability  to  meet  our  obligations  or  continue  our  capital 
expenditure program, and our cash flows, results of operations and financial condition. 

Under  our  existing  debt  instruments,  we  are  subject  to  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$1,650.5 million as of December 31, 2005.  If, however, these and other limitations 
prevent us from completing our capital expenditure program or executing our business plans generally, we may be 
unable to satisfy all of our liquidity and capital resources requirements, which could have a material adverse effect 
on our cash flows, results of operations and financial condition. 

Droughts may result in a decrease in the volume of water billed and the revenue from water supplies, which may 
have a material adverse effect on our company. 

We experience decreases in our water supply from time to time due to droughts.  In the event of prolonged drought, 
the volume of water provided by us may be reduced, although the impact that droughts have  may vary across our 
different water supply systems.  Throughout 2003, rain levels were below average resulting in a weak replenishment 
of  our  reservoirs,  particularly  in  the  Cantareira  System,  the  largest  system  in  the  São  Paulo  Metropolitan  Region.  
The effects of this drought continued to impact our systems through 2004.  In order to minimize the effects of this 
drought, in March 2004 we approved a water consumption reduction incentive program based on a bonus system, 
pursuant to which customers that achieved their consumption reduction goal would be entitled to a 20.0% discount 
on their water bill.  This incentive program ended on September 15, 2004 and encompassed most of the customers in 
the São Paulo Metropolitan Region, resulting in a reduction of our revenue from water and sewage services provided 
to the São Paulo Metropolitan Region by R$74.1 million.  We cannot assure you that any drought in the future will 
not materially adversely affect our water supply and, accordingly, our cash flows, results of operations and financial 
condition. 

Potential  costs  of  environmental  compliance  as  well  as  potential  environmental  liability  may  have  a  material 
adverse effect on our company. 

Our facilities are subject to many Brazilian federal, state and local laws and regulations relating to the protection of 
health  and  the  environment.    We  have  made,  and  will  continue  to  make,  substantial  expenditures  to  comply  with 
these provisions.  In addition, because environmental laws and their enforcement are becoming more stringent, our 
capital  expenditures  and  expenses  for  environmental  compliance  may  increase  substantially  in  the  future.    The 
amount of investments that we make in any given year is subject to limitations imposed by the State.  Expenditures 
required for compliance with environmental regulation  may result in reductions in other strategic investments that 
we  have  planned,  which  could  negatively  affect  our  profitability.    We  could  also  be  exposed  to  criminal  and 
administrative  penalties,  in  addition  to  indemnification  obligations,  for  possible  damage  for  non-compliance  with 
environmental  laws  and  regulations.    Currently,  we  are  party  to  a  number  of  environmental  lawsuits  and 
administrative  proceedings,  including  civil  public  actions  and  criminal  proceedings.    Any  material  unforeseen 
environmental costs and liabilities may have a material adverse effect on our future financial performance. 

14 

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

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 our business or financial condition.  
Based on advice we received from our lawyers, we have provisioned a total aggregate amount of R$612.4 million as 
of  December  31,  2005  to  cover  probable  losses  related  to  legal  proceedings.    This  provision  does  not  cover, 
however, all legal proceedings involving monetary claims filed against us.  Any unfavorable judgment in relation to 
these proceedings may have an adverse effect on our cash flows, results of operations and financial condition. 

Because we are not insured for all business-related and environmental-related contingencies, the occurrence of 
any such event may have a material adverse effect on our future financial performance. 

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 our 
future financial performance. 

Risks Relating to Brazil 

Brazilian economic, political and other conditions may have a material adverse effect on our business. 

The Brazilian economy has been characterized by significant involvement on the part of the Brazilian government, 
which often changes monetary, credit and other policies to influence Brazil’s economy.  The Brazilian government’s 
actions  to  control  inflation  and  affect  other  policies  have  often  involved  wage  and  price  controls,  currency 
devaluations, increases  in  the Central Bank’s  base interest rates,  capital  controls and limits on imports, as  well as 
other measures, such as the freezing of bank accounts. 

Actions  taken  by  the  Brazilian  government  concerning  the  economy  may  have  important  effects  on  Brazilian 
corporations and other entities, including us, and on market conditions and prices of Brazilian securities, including 
our equity and debt securities.  Our financial condition and results of operations may be adversely affected by the 
following factors or the Brazilian government’s response to them: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

currency devaluation and other exchange rate movements; 

inflation; 

currency exchange control policies; 

social instability; 

price instability; 

energy shortages; 

interest rates; 

liquidity of domestic capital and lending markets; 

tax policy; and 

other political, diplomatic, social and economic developments in or affecting Brazil. 

15 

 
The Brazilian Congress is currently conducting investigations, among other issues, in relation to allegations related 
to  political  campaign  contributions  which  were  not  accounted  for  or  disclosed,  including  contributions  made  to 
several  important  members  of  the  present  administration.    Such  allgations  have  resulted  in  the  replacement  of 
important  government  ministers  and  are  occupying  a  significant  portion  of  the  agenda  of  the  Brazilian  Congress.  
These investigations could adversely affect public confidence, and any resulting reduction of economic activity in 
Brazil and could adversely affect our results of operations and the price of our shares and ADSs.  

A presidential election will be held in Brazil in October 2006.  The run-up to the presidential election may result in 
changes in existing policies, and the post-election administration may seek to implement new policies.  In the years 
from  2001  to  2005  the  Brazilian  economy  grew  at  an  average  annual  rate  of  2.2%,  and  the  post-election 
administration may face domestic pressure to revise current economic policies to achieve higher growth rates.  We 
cannot predict what policies will be adopted by the Brazilian government and whether these policies will negatively 
affect the economy or our business or financial condition or results of operations. 

Devaluation of the real could adversely affect our ability to service our foreign currency-denominated debt, and 
could lead to a decline in the market price of our shares or ADSs. 

The  Brazilian  currency  has  been  devalued  frequently  during  the  last  four  decades.    Throughout  this  period,  the 
Brazilian  government  has  implemented  various  economic  plans  and  utilized  various  exchange  rate  policies, 
including sudden devaluations, periodic  mini-devaluations (during which the frequency of adjustments has ranged 
from  daily  to  monthly),  exchange  controls,  multiple  exchange  rate  markets  and  a  floating  exchange  rate  system.  
From time to time, there have been significant fluctuations in the exchange rates between the Brazilian currency and 
the  U.S. dollar  and  other  currencies.    For  example,  in  2001  and  2002,  the  real  devalued  15.7%  and  34.3% 
respectively, while appreciating 22.3% in 2003, 8.8% in 2004 and 13.4% in 2005 against the U.S. dollar. 

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  substantial  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$1,576.0 million  as  of  December  31,  2005,  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 13.4% appreciation of the real against the U.S. dollar in 2005, which amounted to 
R$312.1 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  would  reduce  the  U.S. dollar  value  of 
distributions and dividends on our ADSs and could reduce the market price of our shares or ADSs.  

The Brazilian government’s actions to combat inflation and public speculation about possible future action may 
contribute significantly to economic uncertainty in Brazil. 

Historically, Brazil has experienced high rates of inflation.  Inflation itself as well as governmental efforts to combat 
inflation have had significant negative effects on the Brazilian economy in general.  Inflation, action taken to combat 
inflation and public speculation about possible future action has also materially contributed to economic uncertainty 
in Brazil and to heightened volatility in the Brazilian securities markets. 

Inflation, as measured by the General Price Index-Market, or the IGP-M (Índice Geral de Preços de Mercado), was 
8.7% in 2003, 12.4% in 2004 and 1.2% in 2005.  There can be no assurance that levels of inflation in Brazil will not 
increase  in  future  years  and  have  a  material  adverse  effect  on  our  cash  flows,  results  of  operations  or  financial 
condition.    If  Brazil  experiences  significant  inflation  in  the  future,  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 confidence in Brazil, so that the market price of 
our equity and debt securities declines. 

16 

 
Brazilian law might permit claims against our shareholders for harm to the environment. 

Brazilian  Law  No. 9,605  of  February  12,  1998  provides  that  the  corporate  structure  of  a  company  may  be 
disregarded if  it impedes recovery for undue harm to the environment.   We cannot assure you that, in the case of 
claim  for  environmental  damage  under  this  law,  liabilities  would  be  limited  to  shareholders  capable  of  exercising 
control  over  the  company  at  the  time  of  such  environmental  damage.    Accordingly,  if  we  were  unable  to  redress 
claims  against us for environmental damages, which  might happen, for  example, if we were to become  insolvent, 
our shareholders and the members of our management might become liable for those claims.  We are not aware of 
any successful assertion of claims against any shareholders of any Brazilian corporation under this law and cannot 
predict the circumstances in which this might happen. 

Because electrical power is essential to our operations, power shortages, rationing or instability of the electricity 
supply or significant increases in electricity tariffs may adversely affect our business. 

We are one of the major power consumers in the state of São Paulo and the use of electrical power is essential to our 
operations.    In  May  2001,  the  Federal  Government  announced  measures  to  reduce  power  consumption  in  several 
regions  of  Brazil,  including  areas  where  we  operate.    We  were  not  subject  to  such  measures  because  we  render 
essential  services.    However,  instability  of  the  power  supply  has  caused  and  may  cause  in  the  future  material 
damages to our water and sewage systems which could adversely affect our business.  In addition, material shortages 
or reduction in the power supply (including those due  to rationing  programs)  may adversely impact our results of 
operations and financial condition.  Electricity tariffs increased by an average of 7.86% during the course of 2005, 
which  in  turn  led  to  a  R$37.9 million  increase  in  our  electric  power  costs  in  2005  compared  to  2004.    Further 
significant  increases  in  electricity  tariffs  may  have  an  adverse  impact  on  our  results  of  operations  and 
financial condition. 

Risks Relating to our Common Shares and ADSs 

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  for  approximately  six  months  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. 

Holders of our common shares and ADSs may not receive any dividends or interest on shareholders' equity. 

According  to  our  by-laws,  we  must  generally  pay  our  shareholders  at  least  25.0%  of  our  annual  net  income  as 
dividends  or  interest  on  shareholders'  equity,  as  determined  and  adjusted  under  the  Corporate  Law  Method.  This 
adjusted income may be capitalized, used to absorb losses or otherwise appropriated as allowed under the Corporate 
Law Method and may not be avai1able to be paid as dividends or interest on shareholders' equity. We may not pay 
dividends  or  interest  on  shareholders'  equity  to  our  shareholders  in  any  particular  fiscal  year  if  our  Board  of 
Directors determines that such distributions would be inadvisable in view of our financial condition.

If  a  holder  exchanges  ADSs  for  common  shares,  he  or  she  risks  losing  the  ability  to  remit  foreign  currency 
abroad and 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 a holder decides to exchange his or 
her ADSs for the underlying common shares, he or she 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 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, he or she 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, he or she 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. 

The relative volatility and illiquidity of the Brazilian securities market may substantially limit a holder’s ability to 
sell the common shares underlying our ADSs at the prices and time he or she desires. 

The  Brazilian  securities  markets  are  substantially  smaller,  less  liquid,  more  concentrated  and  more  volatile  than 
major securities markets in the United States and other jurisdictions.  The relatively small market capitalization and 
illiquidity  of  the  Brazilian  equity  markets  may  substantially  limit  a  holder’s  ability  to  sell  the  common  shares 
underlying our ADSs at the price and time he or she desires. 

A  holder  of  common  shares  or  ADSs  may  face  difficulties  in  protecting  his  or  her  interests  as  a  shareholder 
because we are a Brazilian 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  such  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 
execution 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 

18 

 
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, 2005, we had 28,479,577,827 common shares 
outstanding,  including  14,313,511,871  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 US securities laws. 

Under our by-laws, any disputes among us, our shareholders and our management with respect to the application of 
Novo  Mercado  rules,  the  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 holders of ADSs, and disputes between us and our shareholders, including holders of ADSs, 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 a holder of ADSs predicated upon the US 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 US securities laws in the US 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 
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,  a  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 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 ADS holders of their voting rights through the depositary with respect to the underlying 
common shares.  However, there are practical limitations upon the ability of ADS 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.    ADS  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 holders of ADSs 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, 
ADS 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  ADS 

19 

 
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. 

Developments in other emerging market countries may adversely affect the Brazilian economy and, therefore, the 
market prices of our common shares and ADSs, as well as of our debt securities. 

The market for securities issued by Brazilian companies is influenced by economic and market conditions in Brazil 
and,  to  varying  degrees,  market  conditions  in  other  Latin  American  and  emerging  market  countries.  Although 
economic  conditions  are  different  in  each  country,  the  reaction  of  investors  to  developments  in  one  country  may 
have a material adverse effect on the market value of securities of Brazilian companies. If there is a crisis in another 
emerging market country, investor demand for Brazilian securities, including our common shares and ADSs, as well 
as our debt securities may decline. This may adversely affect the trading value of our common shares or ADSs as 
well  as  our  debt  securities  and  any  such  decline  in  trading  value  would  create  obstacles  or  otherwise  impede  our 
access to capital markets and financing for our future operations. 

Changes in Brazilian tax laws may have an adverse impact on the taxes applicable to a disposition of the ADSs. 

According to Law No. 10,833, enacted on December 29, 2003, the disposition of assets located in Brazil by a non-
resident  to  either  a  Brazilian  resident  or  a  non-resident  is  subject  to  taxation  in  Brazil,  regardless  of  whether  the 
disposition  occurs  outside  or  within  Brazil.  In  the  event  that  the  disposition  of  assets  is  interpreted  to  include  a 
disposition of the ADSs, this tax law could result in the imposition of withholding taxes on a disposition of ADSs by 
a  non-resident  of  Brazil  to  another  non-resident  of  Brazil.  Due  to  the  fact  that  no  judicial  guidance  as  to  Law 
10,833’s  application  yet  exists,  we  are  unable  to  predict  whether  an  interpretation  applying  such  tax  laws  to 
dispositions of ADSs between non-residents could ultimately prevail in the courts of Brazil.

INFORMATION ON THE COMPANY 

General 

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 
corporation law.  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, operate and market basic sanitation services throughout the 
territory of the state of São Paulo, including the capture, collection, processing and distribution of water, as well as 
the  collection,  removal  and  final  disposal  of  sewage  and  sludge.    Since  March 2006,  we  are  also  authorized  to 
provide these services in all national 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,  or  IBGE,  the  state  of  São  Paulo  is 
Brazil’s  most  populous  state  and  the  state  with  the  highest  GDP  in  Brazil.    We  had  net  revenue  from  sales  and 
services  of  R$4,953.4 million  (U.S.$2,116.2 million)  and  net  income  of  R$865.6 million  (U.S.$369.8 million)  for 
total  assets  of  R$17,435.2 million  (U.S.$7,448.7 million)  and  shareholders’  equity  of 
2005. 
R$8,482.5 million (U.S.$3,623.9 million) as of December 31, 2005. 

  We  had 

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.  Until December 2002 we divided our service territories into three regions:  the São Paulo 
Metropolitan  Region,  the  Interior  Region  and  the  Coastal  Region.    During  2003  we  reorganized  our  corporate 
management structure by consolidating the municipalities which we serve in the interior and coastal regions into a 
single management unit we call “Regional Systems”.  Under this new structure, the São Paulo Metropolitan Region 
and  the  Regional  Systems  accounted  for  75.5%  and  24.5%  of  our  gross  revenue  from  sales  and  services  in 
2005, respectively. 

As  of  December  31,  2005,  we  distributed  water  to  approximately  22.6 million  people,  which  we  believe  includes 
approximately 60% of the urban population of the state of São Paulo, through approximately 58,000 kilometers of 
water  pipes  and  mains  to  approximately  6.5 million  water  connections.    As  of  December 31,  2005,  we  provided 
sewage  services  to  approximately  18.3 million  people  through  37,181  kilometers  of  sewer  lines  to  approximately 
4.9 million  sewage  connections.    In  addition,  we  currently  sell  water  on  a  wholesale  basis  to  six  municipalities 
having an estimated urban population of approximately 3.1 million inhabitants. 

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 Energy, Water Resources and Sanitation Secretariat of the State as 
part of the overall strategic planning for the State.  The majority of the members of our Board of Directors and our 
Executive Committee are nominated by the State Council for Protection of Capital of the State (Conselho de Defesa 
de Capitais do Estado de São Paulo—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 Energy, Water Resources and Sanitation Secretariat and of the state of 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.

State of São Paulo 

The state of São Paulo is one of 26 states that, together with the Federal District of Brasilia, 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, 2005 of 40.2 million. 

As of December 31, 2005, the City of São Paulo, the state of São Paulo’s capital, had an estimated population of 
10.8 million,  with  19.2 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, 
1999 Revision.  The São Paulo Metropolitan Region accounted for approximately 48% of the population of the state 
of São Paulo as of December 31, 2005. 

According to IBGE, in 2003, the most recent year for which this data is available, the GDP of the state of São Paulo 
was  approximately  R$494.8 billion,  representing  approximately  32%  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. 

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,  whose  purpose  was  to 
provide potable water wholesale 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 

22 

 
with  such  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  such  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. 

Recovery Program 

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  enterprise  whose  financial  performance  was 
then only a secondary consideration of the State. 

We also had significant and increasing levels of unpaid accounts 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. 

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. 

Our overall strategy is based upon five guiding principles: 

• 

• 

• 

• 

Growth:  to provide quality services to a larger customer base through an increase in  number of 
consumers, the expansion of our base of operation, the improvement of our financial results and 
the optimization of our intangible assets and know-how; 

Quality:  to  provide  basic  sanitation  services  meeting  the  demands  of  our  consumers  and  of  the 
community  we  serve  at  appropriate  cost,  compliance  with  technical,  legal  and  transparency 
requirements;  

Universalization of Water Services: to provide water to our customers at all times, meeting their 
demands  for  quality  and  availability.  We  intend  to  achieve  that  by  using  water  sources  with 
adequate water levels, water treatment facilities with suitable capacity and a distribution network 
that can fulfil the demand; 

Social, Economic and Environmental Sustainability:  to ensure the sustainability of our business 
and growth in a balanced manner. We intend to achieve such sustainability by developing social 
inclusion mechanisms (such as social tariffs), the implementation of balanced and profitable tariffs 
and the protection of water sources and the adequate final disposal of sewage and sludge; 

23 

 
• 

Political/Institutional:    to  develop  closer  relationships  with  municipal  governments  and  with 
customers by means of decentralized business units, increased participation in decisions affecting 
municipalities and anticipation of the demands of all stakeholders. 

Using the "Balanced Scorecard" methodology, a methodology that enables the company to monitor and follow the 
implementation  of established strategies, these five  guiding principles were  broken down  into strategic  initiatives, 
among which we highlight the following: 

• 

• 

• 

• 

Ensure  the  Quality  and  Availability  of  Our  Water  and  Sewage  Services  in  Our  Existing  Service 
Area.  Our goal is to maintain universal coverage of water services and to increase penetration of 
sewage  collection  and  treatment  services  with  a  high  standard  of  quality  and  availability.    A 
significant  portion  of  our  capital  expenditure  program,  which  will  require  total  expenditures  of 
approximately R$4.8 billion between 2006 and 2010, is designed to achieve this goal.  We aim to 
continue providing universal water coverage and meet population growth by adding 845,000 water 
connections  by  2010.    We  also  intend  to  increase  our  sewage  coverage  ratio  to  86%  by  adding 
1,080,000 sewage connections by 2010.  

Maintain  our  Existing  Concession  Base  and  Obtain  Additional  Concessions  and  Operations 
Outside our Existing  Concession Areas.   Our goal  is to renew all of  our  existing  concessions as 
they expire.  We have assembled a special task force to address concession expiration in a timely 
and  effective  manner,  including  the  introduction  of  new  processes  to  increase  efficiency  in 
connection with the implementation of new and/or renewed contracts.  In addition to this ongoing 
effort, we regularly explore the possibility of obtaining additional water and sewage concessions 
in municipalities in the state of São Paulo in which we currently have no operations or to which 
we  currently  supply  water  solely  on  a  wholesale  basis.    This  represents  a  total  population  of 
approximately 15.4 million.  We evaluate possible expansion opportunities in terms of proximity 
to  our  existing  service  areas  and  projected  positive  contributions  to  our  financial  performance.  
From March 2006, we have been authorized to provide services outside the State of São Paulo, in 
other  national  and  international  regions.  Therefore,  we  intend  to  study,  and  take  advantage  of, 
opportunities presented in other Brazilian states and in other countries to expand our services and 
increase our market share. In order to implement this strategy, we have created a New Businesses 
area that reports directly to our President, to analyse opportunities derived from this change in our 
area of operations. 

Set Our Tariffs to Cover Our Costs of Operations and to Provide a Return on Investment.  Current 
tariff regulations allow us to set tariffs more aggressively and to tailor them to the peculiarities of 
each service, the diversity of the  regions  covered  and the social and  economic conditions  of the 
end  user.    We  periodically  adjust  our  tariffs  for  water  and  sewage  services  using  a  transparent 
formula which accounts for inflation, covers our operating costs and other expenses and provides 
for return  on investment.   We generally adjust  our tariffs  once a  year for a  period of at least 12 
months.  In 2005, we increased our tariffs by 9.0%, effective as of August 31, 2005. During 2005, 
we continued with studies initiated in 2004 regarding the restructuring of our tariffs. These studies 
include  a  study  of  our  costs,  taking  into  account  economic  efficiency,  future  costs  of  operations 
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  account  specific  characteristics  and 
commercial  potential,  as  well  as  proposals  for  improvement  of  our  commercial  policies.  These 
studies were finalized in January 2006, and have been delivered to our executive committee and 
Board  of  Directors  and  the  resulting  recommendations  are  currently  being  detailed  for 
implementation.  

Continue  to  Reduce  Operating  Costs  and  to  Increase  Productivity  and  Profitability.    We  are 
continuing our efforts to lower operating costs and to increase productivity.  In order to achieve 
this, we plan to continue reducing our total salary and payroll expenses by decreasing the number 
of  our  employees,  automating  some  of  our  operations,  improving  operational  processes,

implementing integrated planning and intensifying and further investing in internal technological 
research and development.   

Improve Operating Efficiency and Reduce Water Losses.  We seek to reduce both physical water 
losses  (due  primarily  to  leakage  from  our  water  system)  and  non-physical  water  losses  (due  to 
meter  errors  that  prevent  proper  accounting  of  water  use,  improper  classification  of  customers, 
fraud  and  illegal  connections).    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  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 aim to reduce water losses in the São Paulo Metropolitan Region and in the Regional 
Systems,  from  626  litres/connections  per  day  and  361  litres/connections  per  day  respectively,  in 
2005, totalling 520 litres/connections per day in 2005 to 450 litres/connections per day in the São 
Paulo Metropolitan Region and 280 litres/connections per day in the Regional Systems, totalling 
382 litres/connections  per  day  in  2010.    We  are  aiming  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, to minimize losses. 

Continue  to  Diversify  Sources  of  Financing  and  Reduce  Levels  of  Indebtedness.    Our  goal  is  to 
continue to identify and secure diverse sources of  funds, both public and private, in the national 
and international markets, and to restructure and refinance our indebtedness in order to reduce and 
balance our overall exposure to different sources of financing.  During 2005, we reduced our total 
indebtedness by 5.48%, from R$7,050.7 million to R$6,664.2 million. There was also a significant 
reduction  in  our  foreign  currency  indebtedness  in  a  total  percentage  of  41.2%,  from  R$2,680.9 
million  to  R$1,576.0  million  in  2005  where  32.3%  was  reduced  by  amortization  of  debt.  These 
reduction on our indebtedness levels during 2005 was achieved mainly by the refinancing of part 
of  our  U.S.$  denominated  debt,  exchanging  it  for  longer-term  domestic  issuance  of  debentures.  
We  are  also  exploring  and  pursuing  structured  finance  alternatives.    In  2006,  we  established  a 
mutual fund (Fundo de Investimento em Direitos Creditórios) through which we were able to raise 
R$250 million through the securitization of receivables. 

Improve  Collection  of  Overdue  Accounts  Receivable.    We  are  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 amounts overdue and in some cases exploring  opportunities to swap the amounts overdue in 
exchange  for  the  rights  and  infrastructure  to  operate  the  water  and  sewage  systems  of  certain 
municipalities.   

Maintain  Close  Relationships  with  Municipal  Governments  and  with  Customers  in  Order  to 
Increase  Customer  Loyalty.    We  are  seeking  to  develop  closer  relationships  with  the  municipal 
governments and with customers that we serve in order to increase customer loyalty and thereby 
increase  revenues.    We  are  also  working  to  improve  customer  relations  by  shortening  response 
times for customer installations as well as through a focused public relations program to enhance 
our  image.  We  are  also  working  on  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 and maintain customer loyalty. 

Continue  our  Commitment  to  Our  Employees  and  to  the  Community.  We  are  focused  on  our 
human  resources  policies,  which  are  vital  to  our  competitiveness  and  growth.  We  intend  to 
continue investing in training for our employees to provide the best service to our consumers as 
well  as  prepare  them  to  act  in  new  markets  and  businesses  which  we  aim  to  tap  and  in  an 

25 

 
increasingly competitive environment. During 2005, our staff (including managers and employees 
of  technical  and  operational  areas)  attended  several  courses  on  Social  and  Corporate 
Responsibility and Private Social Investment.  We are also committed to the community we serve 
and intend to be prepared to achieve excellence in environmental and social responsibility.  

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 and abroad and, at the same time, bolster our results of operations and our financial condition 
and enhance shareholder value. 

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. 

• 

• 

• 

• 

• 

• 

Chief  Executive  Office  —  responsible  for  coordinating  all  management  divisions  in  accordance 
with the policies and directives established by our Board of Directors and Executive Committee, 
performing the coordination, evaluation and control of all functions related to the Chief Executive 
Officer’s  Office,  strategic  planning,  corporate  organization,  corporate  communication, 
audit, ombudsman , new businesses and concession negotiation. 

Corporate Management Office — responsible for marketing, human resources and quality control 
programs,  legal  affairs,  information  technology,  asset  management,  legal  and  procurement, 
and contracts. 

Financial  and  Investor  Relations  Office  —  responsible  for  financial  planning,  raising  and 
allocating  financial  resources  to  all  divisions  within  the  company,  conduct  capital  markets  and 
other  debt  transactions  and  manage  debt  levels,  accounting,  corporate  governance  and  investor 
relations.  This division also monitors and acts as controller for our other divisions. 

Planning  and  Technology Office — responsible  for  integrated technical  planning, environmental 
planning and management, technological development, management and control of water quality, 
strategic  maintenance,  integrated  project  management  and  coordination  and  execution  of 
special projects. 

São Paulo Metropolitan Region Office — responsible for the distribution of water and collection 
of sewage for the São Paulo Metropolitan Region.  The main function of this division is planning, 
operating  and  maintaining  the  water  and  sewage  systems  and  customer  relation  services  in  the 
Metropolitan  Regions,  the  provision  of  wholesale  water  supply  and  sewage  treatment,  and  the 
control  of  the  financial  and  operational  performance  of  its  business  units.    This  office  is  also 
responsible for providing technical support to the autonomous municipalities, and intermediating 
and directly negotiating with local communities and municipalities in order to accommodate both 
the interests of the communities and our commercial interests. 

Regional Systems Office — responsible for the production of water and operation and maintenance 
of water and sewage systems in municipalities in the Regional Systems.  It is also responsible for 
performing the same tasks as the Metropolitan Region Office for the Regional Systems. 

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 State Constitution provides that the State shall assure the correct operation, necessary expansion 

26 

 
and efficient administration of water and sewage services in the state of São Paulo by a company under its control.  
Under applicable  law, we are responsible  for  planning basic water and  sewage  services in  the state  of  São Paulo, 
whilst respecting the autonomy of its municipalities.  The municipalities are empowered to, and commonly do, grant 
long-term concessions to water and sewage companies to provide such services. 

We do not hold a formal concession to provide water and sewage services in the City of São Paulo, which accounts 
for  56.8%  of  our  revenue,  and  in  40  other  municipalities  in  the  state  of  São  Paulo.    None  of  these  other 
municipalities  has  a  significant  population,  other  than  Santos,  which  has  a  population  exceeding  400,000.    We 
believe  that  we  have  a  vested  right  to  provide  water  and  sewage  services  based  upon,  among  other  things,  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  which  formed  us.    In  general,  we  do  not  face  any  competition  in  the 
municipalities in which we provide water and sewage services, and we believe that in those municipalities we have 
an exclusive right to provide such services.  Private water companies currently provide water and sewage services to 
a very small number of municipalities in the state of São Paulo. 

We  also  provide  water  and  sewage  services  in  325  additional  municipalities  in  the  State  pursuant  to  concessions 
granted by the municipalities.  Substantially all of these concessions have 30-year terms. As of December 31, 2005, 
17 of our concessions have expired. Some of the expired concession agreements have been extended for a short term 
while  we  negotiate  the  terms  and  conditions  of  a  final  agreement  with  each  relevant  municipality.    The  new 
agreements may be executed under a new regime provided for by a newly enacted law which establishes principles 
to  be  observed  when  public  consortiums  contract  with  the  municipalities,  with  the  objective  of  allowing  the 
provision of public services to be jointly managed.  Despite the expiration of the agreements, we continue to provide 
water and sewage services to all 17  municipalities.  256 of our concessions are scheduled to expire between 2006 
and 2010, 127 of which are due to expire in 2006 and 30 in 2007. The rest of our concessions will expire between 
2011  and  2034.    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  Office,  is  to 
maintain the existing concessions and/or to acquire new ones. 

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 the relevant 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.  

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 sewage 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 
such concession. 

27 

 
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. 

Following the enactment of the Concessions Law (Law 8,987/95) and of the Consortium Law (Law 11,107/05), all 
concession contracts had to be adapted to 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 concessions 
acquired by Sabesp and the new contracts to be executed after the expiration of the concessions will follow this new 
contract model. 

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 as were used to determine the value of the concession at its 
inception (adjusted for inflation). 

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

There is currently ongoing litigation with respect to municipalities that intend to expropriate our water and sewage 
systems or to terminate concession agreements prior to paying us any indemnification.  For example, 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  Appeals  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,  and  we  can  give  no  assurance  that  the  ultimate  determination  will  be 
favorable  to  us.    Despite  the  pending  lawsuit,  we  continue  to  provide  water  and  sewage  services  to  Santos.    In 
addition, in connection with discussions we had with the municipality of Presidente Prudente, we filed a suit against 
the  municipality  seeking  a  court  decision  determining  the  continuation  of  the  concession  agreement  that  we  have 
with  that  municipality  until  the  indemnification  payment  owed  to  us  in  connection  with  the  return  of  water  and 
sewage system of the Presidente Prudente is made.  The lower court issued a decision in our favour to the effect that 
we  still  continue  to  provide  services  in  the  municipality  until  the  indemnification  provided  for  in  the  concession 
agreeement is paid to us.  The Municipality of Sandovalina has brought a legal action against us aiming to (i) obtain 
the termination of the concession executed with us and (ii) seeking remedies for environmental damages and alleged 
losses caused to the municipality due to our failure to provide sewage treatment, and other damages caused to public 
property.  We have responded with a counterclaim requiring the municipality to pay R$115,400 related to the supply 
of water from December 1999 to 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  systems  of 
Sandovalina, and the lawsuit is still in the fact-finding phase. 

In addition, on March 25, 2004, the Public Attorney’s Office filed a civil action against the Municipality of the City 
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 agreement we entered into with the Municipality of the 

28 

 
City of Itapira.  Although an injunction was granted, the São Paulo state Court of Appeals has stayed the injunction.  
On March 23, 2005, the House of Representatives of Itapira approved a decree revoking the concession agreement.  
In addition, Municipal Law No. 3,730/05 was enacted to revoke an earlier law which authorized the municipality to 
enter  into  the  concession  agreement  with  us.    The  municipality  of  Itapira  has  further  filed  an  action  against  us 
aiming  to  repossess  the  assets  related  to  the  water  and  sewage  services  of  that  municipality  and  obtained  an 
injunction  which  was  later  confirmed  by  a  court  decision.  We  appealed  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 final the decision on this litigation was pending. 

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  include  the  following:  (A)  a 
preliminary proceeding (ação cautelar) started by the Municipality of Guariba seeking a court order requiring us to 
exhibit  documents  and  to  instruct  an  account  revision  proceeding;  (B)  the  Municipality  of  Ribeirão  Pires  has 
proposed preliminary proceedings seeking the exhibition of documents to inspect the services which we provide; (C) 
the Municipalities of Itupeva and Monte Mor have proposed proceedings aimed at obtaining a court order to require 
us to exhibit documents and information in order to evaluate the possibility of renewal of our concession agreement. 

In addition to our concessions, in December 2003, we acquired water and sewage service assets in the Municipality 
of  São  Bernardo  do  Campo  through  the  transfer  of  all  related  assets  from  the  municipality  to  us.    Previously,  we 
provided water to São Bernardo do Campo on a wholesale basis.  The amount paid for the purchase of assets was 
estimated by an economic-financial valuation report, which included the liquidation of the water wholesale supply 
accumulated debt.  See “Item 5.  Operating and Financial Review and Prospects—Liquidity and Capital Resources” 
for information with respect to the São Bernardo do Campo transaction. 

Description of Our Activities 

We provide basic sanitation services, which include the abstraction, treatment, processing and distribution of water, 
as  well  as  the  collection,  removal  and  final  disposal  of  sewage.    We  believe  we  are  one  of  the  largest  water  and 
sewage service providers in the world based on customers in 2005.  We render our services in the state of São Paulo, 
where the City of São Paulo, the largest city in Brazil, is located.  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. 

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  2005,  we  produced  approximately  2,830.1 million  cubic 
meters  of  water.    The  São  Paulo  Metropolitan  Region  currently  is,  and  has  historically  been,  our  core  market, 
accounting for approximately 71.0% of water invoiced by volume.

Includes water invoiced to wholesale customers of 346.2 in 2003, 251.4 in 2004 and 258.7 in 2005, each in millions of cubic meters. 

The difference between the amount of water produced and the amount of water invoiced generally represents both 
physical and non-physical water loss.  See “—Water Distribution” below.  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; 

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.

We can abstract water only to the extent permitted by the Department of Water and Energy of the State and pursuant 
to authorization contracts executed with it.  Under some circumstances, depending on the geographic location of the 
relevant river basin or reservoir, the approval of the National Water Agency 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 17 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 integrated water system of the São Paulo Metropolitan Region.  Resource availability, 

30 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
or amount of water available at the source for public distribution in such areas, is 68.6 cubic meters per second and 
should  increase  to  72.0  cubic  meters  per  second  in  2006,  when  the  planned  extension  and  improvement  in  water 
sources will be concluded.  Total current capacity, or amount of water that can be treated from the integrated water 
system of the São Paulo Metropolitan Region, is 67.7 cubic meters per second and has been designed to reach 70.2 
cubic  meters  per  second  in  2008.    Average  verified  production  or  amount  treated  during  2005  on  the  integrated 
water  system  of  the  São  Paulo  Metropolitan  Region  was  64.8  cubic  meters  per  second.    The  Cantareira, 
Guarapiranga and Alto Tietê systems, as a whole, supply approximately 83.9% of the water we produced for the São 
Paulo Metropolitan Region. 

The Cantareira system accounts for approximately 49.3% of the water that we provide to the São Paulo Metropolitan 
Region, which represented 75.5% of our operating revenue for 2005.  The authorization (outorga) for the Cantareira 
system to use the water in the Piracicaba water basin was renewed by Portaria DAEE n° 1213 on August 6, 2004 for 
a period of ten years.

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 fees 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  such  transfer will be legally allowed.   See “Item  8.   Financial  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 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 2003, 2004 and 2005, 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 905,600 new water connections from 2000 through December 2004 
and 158,300 new water connections in 2005 statewide. 

The  integrated  water  system  of  the  São  Paulo  Metropolitan  Region  services  30  municipalities,  24  of  which  are 
operated directly by us. The other 6 municipalities we service 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  consumer the water is stored  and  transported through a  complex and integrated system 
comprised  of  1,400  km  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, Sabesp aims to 
invest R$964.1 million from the years 2006 until 2010 to increase the company's 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  201  treatment  facilities,  of  which  the  eight  largest,  located  in  the  São  Paulo  Metropolitan 
Region, typically account for approximately 72% of all water we supply.  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 
through the networks  to  maintain  adequate pressure and continuous water supply.   As of  December 31,  2005,  our 
water  network  contained  58,000 kilometers  of  water  pipes  and  mains  and  6.5 million  water  connections.    The 
following table sets forth the total number of kilometers of water pipes in our network for the periods indicated.

Approximately  95.0%  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, 2005, our water distribution pipes and mains included: 

• 

• 

27,217 kilometers in the São Paulo Metropolitan Region; and 

30,783 kilometers in the Regional Systems. 

We have 314 storage tanks in the São Paulo Metropolitan Region with a total capacity of 1.8 million cubic meters, 
and  1,664  storage  tanks  in  the  Regional  Systems.    We  have  139  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  high  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 

32 

 
 
 
measurements.    After  completion  of  installation,  the  customer  has  a  fiduciary  duty  to  the  network  and  the  water 
meter.

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  (a) the 
difference between (i) the total amount of water produced by us (after excluding certain non-physical water losses 
set  out  below)  less  (ii) the  total  amount  of  water  invoiced  by  us  to  customers  divided  by  (b) the  total  amount  of 
water  produced  (after  excluding  certain  non-physical  water  losses  set  out  below)  by  us.    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). 

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  (A) 
average annual water loss per (B) the average number of active water connections multiplied by 365.  This result of 
this calculation is the liters of water lost per connection per day. 

Using this calculation method, in 2005 we experienced 626 litres/connections per day water losses in the São Paulo 
Metropolitan Region and 361 litres/connections per day in the Regional Systems, averaging 520 litres/connections 
per  day.    We  plan  to  reduce  water  losses  in  both  regions  for  450  litres/connections  per  day  for  the  São  Paulo 
Metropolitan Region and 280 litres/connections per day for the Regional Systems, resulting in a total reduction to 
382 litres/connections per day by 2010.  

According to the old method, we experienced 32.4% water losses during 2005. 

Our strategy to reduce water loss has two main objectives: 

• 

• 

first,  a  reduction  in  the  level  of  physical  losses,  which  result  primarily  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 

second,  the  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 
inaccurate 
clandestine  and 
water meters. 

through  upgrading  and  replacing 

illegal  use  by  customers, 

We are taking measures to decrease physical losses by reducing response times to broken pipes and mains to less 
than  24  hours  and  by  better  monitoring  of  non-visible  water  mains  fractures.    We  currently  repair  approximately 
4,000  broken  pipes  and  mains  per  month.    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  during  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 

33 

 
 
 
programmed to feed data to the valve to reduce or increase pressure to the water mains as water 
usage fluctuates.  As of December 31, 2005, we had installed 1,318 valves at strategic points in the 
network, with 841 valves installed in the São Paulo Metropolitan Region and 477 in the Regional 
Systems.  We plan to install additional 132 valves through 2006;  

the  reconfiguration  of  integrated  water  distribution  to  permit  the  distribution  of  water  at  lower 
pressure; and 

routine  operational  leak  detection  surveys  in  high  water  pressure  areas  in  each  case  helping  to 
reduce overall water losses. 

• 

• 

Measures adopted to decrease non-physical water losses include: 

• 

• 

• 

• 

monitoring  and  better  accounting  for  water  connections,  especially  for  large  volume  customers, 
regular  checking  on  customers  which  are  accounted  for  by  us  as  inactive  and  monitoring  those 
non-residential  customers  that  are  accounted  for  as  residential  and  therefore  are  billed  at  a 
lower rate; 

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

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 Federal Law, which requirements are similar to the standards set in the United States and Europe.  Under a 
Health Ministry regulation in Brazil, we have significant statutory obligations regarding the quality of treated water.  
These laws set certain standards that govern water quality. 

Some of our water sources in the southern area of the São Paulo Metropolitan Region contain low quality water due 
to the effects of pollution and algae growth.  Currently, we successfully treat this water to make it potable; however, 
during dry periods of the year, this water retains an unpleasant taste and odor in spite of the treatment.  If restrictions 
on  the  use  of  water  are  imposed  in  the  future  and  if  advanced  treatment  standards  are  not  implemented,  water 
originating from this area may decrease in quality and our customers may use only limited amounts of, or refuse to 
pay for, this lower quality water. 

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 in the São Paulo Metropolitan Region have obtained ISO 9001/2000 certification 
and  four  have  obtained  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. 

All  chemical  products  used  for  water  treatment  are  analyzed  and  follow  strict  specifications  set  out  in 
recommendations made by the National Sanitation Foundation - NSF and ABNT - Associação Brasileira de Normas 
Técnicas (Brazilian Association of Technical Rules). 

Water Source Program.  From time to time, we face significant problems with algae growth, as it causes water to 
have an unpleasant taste and odor.  In order to minimize this problem, we have implemented additional treatment 
processes such as absorption by powdered activated carbon and oxidation by potassium permanganate.  We believe 

34 

 
that all the chemicals used are safe for human consumption, but the algae growth creates significant additional costs 
because of the higher volumes of chemicals used to treat the raw water. 

Algae growth tends to occur mainly in the Guarapiranga Reservoir, but it has also been frequently detected in the 
reservoirs that compose the Rio Grande and Alto Tietê systems.  Algae growth in the Guarapiranga and Rio Grande 
reservoirs  is  basically  due  to  the  discharge  of  untreated  sewage  from  squatters  living  adjacent  to  the  reservoirs  in 
violation of laws intended to protect the watershed.  In the Alto Tietê system the algae growth is mainly caused by 
effluents from the agricultural use of the drained areas. 

We  are  planning  to  participate  in  the  Water  Source  Program  (Programa  Mananciais)  together  with  other 
organizations engaged on the promotion of urban development and social inclusion to mitigate the pollution problem 
in the Guarapiranga and Rio Grande reservoirs.  In this program, we will be responsible for the expansion of sewage 
systems, pre-treatment of streams and development more sophisticated treatment facilities. 

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 
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 removal and final disposal of sewage through our sewage systems and for its 
subsequent disposal  with  or  without  prior treatment.   As  of  December 31, 2005, we collected approximately 82% 
and 72% 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 operate in the state of São Paulo.   

Sewage System.  The function of our sewage system is to collect, remove and dispose sewage.  As of December 31, 
2005,  we  were  responsible  for  the  operation  and  maintenance  of  37,181  kilometers  of  sewer  lines  of  which 
approximately  17,903  kilometers  are  located  in  the  São  Paulo  Metropolitan  Region,  and  19,278  kilometers  are 
located in the Regional Systems. 

The  following  table  sets  forth  the  total  number  of  kilometers  of  sewage  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.  Sewer lines larger than 0.5 meters in diameter are primarily made of concrete.  Our 
sewer  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  by  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  occurring  at  sewage 

35 

 
 
 
 
 
 
 
 
treatment facilities and, therefore, such 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  such 
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  sludge  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 
sewage lines intended to deal with anticipated fractures arising from obstructions caused by system overloads. 

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 serviced by us, with approximately 
50% 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.    For  2005  approximately  57%  and  71%  of  the  sewage  we  collected  in  the  São 
Paulo Metropolitan Region and the Regional Systems respectively, or 61% 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 such capacity are discharged directly, untreated, to inland waters and the 
Atlantic Ocean.  Currently we operate 431 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  CONAMA  Resolution  No.  357/05  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 98.0% 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. 

36 

 
 
 
 
 
The primary treatment process is the principal separation process for suspended solid material present in untreated 
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  which  are 
continuously  replenished  with  recirculated  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 43 activated sludge treatment facilities, each of which also contains a primary treatment facility.  The 
five  largest  activated  sludge  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 aeration ponds where the organic matter is aerobically digested and the treated 
sewage is discharged to receiving waters.  There are 349 secondary treatment facilities in the interior region which 
have treatment capacity of approximately 9.0 cubic meters of sewage per second. 

The  majority  of  sewage  collected  in  the  coastal  region  receives  secondary  treatment  and  disinfection  and  is  then 
discharged into rivers and into the Atlantic Ocean.  We have 65 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  such  bodies  of  water.    Our  capital  expenditure  plan  includes  projects  to  increase  the 
amount of sewage that we treat.  See “—Government Regulation—Sewage Requirements” below. 

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 2005, we produced approximately 44,045 tons of sludge-dry base, of which 43,514 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  for  367  of  the  645  municipalities  in  the state of São Paulo.   The

In addition to serving residential, commercial, industrial and governmental customers in municipalities in which we 
hold  concessions,  we  currently  make  wholesale  sales  of  water  to  six  municipalities  having  a  total  estimated 
population of 3.1 million.  The State is our largest customer. 

Tariffs 

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. 

Although  we  have  the  power  to  set  our  tariffs  for  water  and  sewage  services,  we  traditionally  have  consulted  the 
Governor of the State prior to setting new tariff rates.  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. 

The most recently implemented tariff regulations allow us to more aggressively set tariffs and to more realistically 
cover the operational costs of water and sewage systems.  In addition, the new tariff regulations allow us to calculate 
the water and sewage service tariffs in order to better adequate the tariff value to the peculiarities of each service, the 
diversity of the regions covered and the social and economic conditions of the end user. 

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 (IRT) are separated into two parts (“A” and “B”), where Part “A” encompasses all costs related to electricity; 
water and sewage treatment materials; federal, State and local taxes; and 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 
Extended Consumer Price Index (Indice de Preços ao Consumidor Ampliado—IPCA).   

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.  Customers with high monthly water 
consumption rates pay higher tariffs than our costs of providing such 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 sub-divided 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 consumers; 

“not-for-profit” entities that pay 50.0% of the prevailing non-residential tariff; and 

38 

 
 
• 

government entities that have entered into a water loss reduction agreement with us and pay 75.0% 
of the prevailing non-residential tariff. 

Sewage charges in each region are fixed due to the volume 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. 

The following table sets forth the water and sewage services tariffs by customer category and class charged during 
the years and period stated in the São Paulo Metropolitan Region, which accounted for approximately 75.5% of our 
gross revenue from sales and services in 2005.

In  2005,  the  average  tariff  calculated  for  the  Regional  Systems  Office  was  22%  below  the  average  tariff  of  the 
Metropolitan Office. 

During mid-1999 until mid-2001 we did not raise our tariffs, due to a State policy of not increasing tariffs for 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 new readjustment formula approved by our Board of Directors, in August 2003 we raised our tariffs 

39 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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%.  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.  Part of 
the 11.12% increase is attributable to, among others, the increase in the federal taxes. 

During 2005,  we continued with certain studies initiated in 2004  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 commercial policies. 

These  studies  were  finalized  in  January  2006  and  have  been  delivered  to  our  executive  committee  and  Board  of 
Directors.  The resulting recommendations are currently being detailed for implementation. 

See  “—Government  Regulation—Tariff  Regulation  of  São  Paulo”  below  for  additional  information  regarding 
our tariffs. 

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 and R$1.19 per transaction are charged for collection and 
remittance of these payments. 

Customers must pay their water and sewage bills by the due date for payment if they wish to avoid paying a fine.  
We  generally  charge  a  penalty  fee  and  interest  on  late  bill  payments.    In  2003,  2004  and  2005,  we  received, 
respectively, payment of 90.9%, 94.1% and 90.8% of the amount billed to our retail customers, and 93.8%, 94.4% 
and  91.1%  of  the  amount  billed  to  those  customers  other  than  State  entities,  within  30  days  after  the  due  date.  
Almost all of the amount not paid within 30 days is owed by State customers.  With respect to wholesale sales, in 
2005 we received payment of 60.6% 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. 

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 

40 

 
committees  according  to  strategy  and  complexity.    We  have  historically  spent  up  to  R$4.1 million  per  year  on 
research and development.  We have also partnered with several research institutions. 

Electricity Consumption 

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

Electricity  prices  have  a  significant  impact  on  our  results  of  operations.  An  average  increase  of  17.5%  in  2004 
negatively  impacted  our  results  of  operations.    See  “Item  5.    Operating  and  Financial  Review  and  Prospects—
Results of Operations” above.  

Capital Expenditure Program 

Currently, 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 targets in the municipalities we serve: 

• 

• 

• 

• 

to continue to meet the maximum demand for treated water; 

to expand the percentage of households connected to our sewer system; 

to increase the treatment of sewage collected; and 

to increase operating efficiency and reduce water losses. 

From 1998 through 2004, our capital expenditure program included capital expenditures totaling R$4.8 billion in the 
aggregate, primarily to build up our infrastructure and for our program to reduce water losses.  We have budgeted 
capital expenditures totaling approximately R$4.8 billion in the aggregate during the period between 2006 and 2010.  
We spent R$600.9 million in 2004 and R$678.2 million in 2005. 

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

Our capital expenditure program from 2006 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 which we serve.  The following is a brief description of 
three 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 

41 

 
 
 
 
 
projections for the  São Paulo Metropolitan Region.  In 2005, we have invested R$63.7 million in this region and 
have budgeted for capital expenditures of R$964.1 million from 2006 through 2010. 

Tietê Project 

The  River  Tietê  crosses  the  São  Paulo  Metropolitan  Region  and  receives  most  of  the  Region’s  run-off  and 
wastewater.    The  environmental  state  of  the  river  reached  a  critical  level  and  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 River Tietê by installing sewage collection lines along the banks of the River Tietê and its 
tributaries.  These lines collect raw sewage and deliver it to our sewage treatment facilities.  The first stage of the 
program  was  completed  by  Sabesp  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 plants and invested a 
total  of  U.S.$900.0 million,  of  which  U.S.$450.0 million  was  financed  by  the  Inter-American  Development  Bank 
and U.S.$450.0 million was funded by us. 

We  made  capital  expenditures  with  respect  to  the  first  phase  of  the  Tietê  Project  of  U.S.$900.0 million.    As  of 
December  31,  2005,  we  owed  U.S.$284.3 million  to  the  Inter-American  Development  Bank  for  the  financing  it 
provided.    We  now  provide  secondary  treatment  to  approximately  60%  of  the  sewage  collected  in  the  São  Paulo 
Metropolitan  Region.    The  five  principal  sewage  treatment  plants  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 11 cubic 
meters  of  sewage  per  second.    Currently,  raw  sewage  is  delivered  to  our  secondary  treatment  facilities  along  the 
River  Tietê  and  the  River  Tamanduatei  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 U.S.$400.0 million from 2000 through 2007, U.S.$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 
BNDES for R$60.0 million and R$180.0 million, respectively, to finance this second phase.  Through December 31, 
2005, we have spent U.S.$259.6 million on this 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.  

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$195.0 million, 
R$212.0 million and R$222.0 million on such projects in 2003, 2004 and 2005, respectively, and we have budgeted 
for additional capital expenditures of approximately R$1.7 billion in the period from 2006 to 2010.  

Environmental Recovery Program for the Baixanda Santista Metropolitan Region 

On August 6, 2004, we entered into a credit agreement with the Japan Bank for International Cooperation for the 
financing  of  the  Environmental  Recovery  Program  for  the  Baixada  Santista  Metropolitan  Region,  which  was 
guaranteed by the Republic of Brazil, for a total amount of R$422.8 million.  The total investment to be made with 
respect to this project is R$777.9 million and the balance will be our responsibility.  The first disbursements under 
this agreement began in January 2006.  The  main goals of this program are to improve and expand the water and 
sewage systems in the municipalities making up the Baixanda Santista Metropolitan Region. 

42 

 
Competition 

We can foresee at least two possibilities for the increase of Sabesp’s participation in the domestic sanitation market.  
There  are  272  municipalities  in  the  state  of  São  Paulo  that  operate  their  own  water  and  sewage  systems  and  that 
collectively have a population of approximately 12.2 million, or approximately 30% of the population of the state of 
São  Paulo.    In  addition,  there  are  private  water  companies  which  provide  water  and  sewage  services  to  a  small 
number of municipalities, which may indicate a potential opportunity for the increase of Sabesp’s market share. 

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 commercial 
and industrial customers in order to help retain such customers.  Additionally, we already face competition for the 
disposal of non-residential, commercial and industrial sludge in the São Paulo Metropolitan Region. 

Government Regulation 

In Brazil, water and sewage services, although not specifically regulated, are subject to extensive Brazilian federal, 
state and, in certain respects, local laws and regulations governing, among other things: 

• 

• 

• 

• 

• 

• 

• 

General 

the granting of concessions to provide water and sewage services; 

the implementation of public-private partnerships; 

public bidding requirements for appointment of water and sewage service provider; 

water usage; 

water quality and environmental protection; 

tariffs for water and sewage services; and 

governmental  restrictions  on  the  incurrence  of  indebtedness  (which  are  applicable  to  state-
controlled companies). 

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

Article 216 of the State of São Paulo Constitution 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. 

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. 

Pending Legislation 

On  May  23,  2005,  a  new  proposed  law  (“Proposed  Law  No.  5,296”)  was  submitted  to  the  Brazilian  House  of 
Representatives.  The proposed law does not define whether the entity responsible for sanitation services will be the 
state or the municipality, but divides sanitation services into two categories: “local interest” sanitation services and 

43 

 
“integrated’ sanitation services.  Services in connection with the distribution of water and sewage collection will be 
attributed  to  the  local  interest,  and  thus  the  municipality  will  always  be  the  entity  responsible  for  those  services.  
Other services, such as water treatment, may also considered to be of local interest, if they are rendered to a single 
municipality,  otherwise  they  will  be  considered  to  be  of  integrated  interest.    A  state,  however,  might  also  be 
responsible for those services if it enacts a State Complementary Law which establishes metropolitan areas, urban 
agglomerations and micro-regions and includes those services in the category of common interest sanitation services 
to be planned, regulated, and controlled by that state. 

According  to  Proposed  Law  No.  5,296,  any  entity  responsible  for  sanitation  services  will  be  required  to  abide  by 
guidelines relating to planning, regulating, and controlling those services.  If the entity responsible does not follow 
those guidelines, it will not be eligible for voluntary funds from the Federal Government.  The provision of sanitary 
services, either in the local interest or the integrated interest, may be made by the responsible entity itself, by state 
companies  created  to  provide  that  service,  or  indirectly  by  concession  or  an  agreement  between  the  responsible 
entity and any other state or private company.  In any case, the entity responsible for the provision of the services 
will not be able to plan, regulate or fix tariffs. 

Proposed Law No. 5,296 is being analyzed by the House of Representatives and has recently been attached to other 
proposed federal laws, in connection with the regulation of sanitation services. 

Additionally, Proposed Law No. 155/2005 has also recently been submitted to the Brazilian Federal Congress.  This 
proposed  law,  which  has  been  under  consideration  by  the  Brazilian  Senate  since  May  11,  2005,  does  not  define 
whether  the  entity  responsible  for  the  sanitation  services  will  be  the  state  or  the  municipality,  but  it  also  divides 
sanitation services into two categories: “local interest” sanitation services and “common interest” sanitation services.  
According  to  the  proposed  law,  the  holder  of  the  sanitation  services  will  define  the  entity  responsible  for  the 
regulation  of  those  services,  and  will  establish,  among  other  things  investment  plans  and  tariff  policies.    This 
proposed law also provides that the provision of sanitation services may be interrupted if the user of those services 
does not make timely payments. 

Both  Houses of Representatives have agreed upon  the  creation of  a joint committee (comissão mista) that  will  be 
responsible for the organization and implementation of the proposed regulation for the water and sewage services in 
Brazil. 

We cannot assure you when or if any of the legislation described above will be adopted, the final form of these laws 
if they are approved, or how this legislation would affect our business. 

Concessions 

Concessions for water and sewage services are evidenced by contracts between the state or municipal government, 
as the case may be, and a concession under which the concessionaire is granted the right to supply these services in a 
particular  municipality  or  region.    Our  concessions  usually  have  a  contractual  term  of  not  longer  than  30  years, 
although  a  number  of  our  concessions  are  of  unlimited  duration.    However,  our  concessions  generally  may  be 
terminated at any time if certain quality and safety standards are not met or if there is a default under the concession 
contract.    A  majority  of  our  concessions  are  automatically  renewable,  though  we  often  renegotiate  terms  and 
conditions  unless  notice  of  rescission  is  received  by  the  non-rescinding  party  at  least  six  months  prior  to  the 
expiration date of the concession.  A municipality that elects to take control of its water and sewage services must 
either provide such services itself, auction the concession to potential concessionaires through a competitive public 
bidding process, or enter into agreements with a public entity directly.  Although the State Constitution provides that 
the  relevant  municipality  would  have  to  pay  us  the  non-amortized  book  value  of  our  assets  relating  to  that 
concession and assume any related indebtedness, exclusive of any amounts paid to us by the relevant municipality 
upon  any  termination  or  non-renewal  of  a  concession,  such  a  termination  payment  may  not  be  paid  and  any 
termination  could  adversely  affect  our  cash  flows,  results  of  operations  and  financial  condition.    In  addition, 
municipalities hold elections for the office of Mayor every four years.  If certain municipalities choose not to renew 
their concessions, it could adversely affect our cash flows, results of operations and financial condition. 

44 

 
Federal legislation enacted in 1995, and subsequently amended, governs the granting of concessions in Brazil.  The 
Federal  Concessions  Law  regulates  the  granting  of  concessions  by  federal,  state  and  municipal  governments.    In 
addition, the Federal Public  Bidding Law sets forth  the bidding procedures related to the granting of  concessions.  
At the São Paulo State level, the State Concessions Law corresponds to the Federal Concessions Law, and the State 
Public Bidding Law corresponds to the Federal Public Bidding Law.  In the event of any conflict between federal 
and state law, federal law prevails. 

Concessions Laws 

The Federal Concessions Law and the State Concessions Law require that a concession granted by a public entity be 
based  on  a  public  bidding  process.    The  Federal  Public  Bidding  Law  provides,  however,  that  the  public  bidding 
process can be waived in certain circumstances, including in the case of services to be rendered by a public entity 
created for such specific purposes prior to the enactment of that law, provided that the prices for such services are 
compatible with those prevailing in the market.  In addition, a provision of the Brazilian Constitution provides for 
waivers  of  the  public  bidding  requirement  in  similar  situations.    Based  on  this  provision,  we  were  granted 
concessions  by  municipalities  after  enactment  of  the  Brazilian  Constitution  without  a  public  bidding  process, 
although  under  current  law  we  may  be  required  to  bid  to  acquire  new  concessions.    We  did  not  have  any  of  our 
concessions cancelled or revoked following promulgation of the Federal Concessions Law.  The requirements of the 
Federal  and  State  Concessions  Laws  will,  however,  govern  the  grant  of  new  concessions  to  us  in  the  future.    In 
February 1998, the Attorney General of the State, in response to a request we made, delivered an opinion that any 
municipality in the state of São Paulo may grant to us a concession to operate the municipality’s water and sewage 
services  without  having  to  resort  to  a  public  bidding  process.    In  April  1998,  a  State  court  issued  a  judgment 
substantially  to  the  same  effect.    However,  in  2005  the  Superior  Court  of  Justice  declared  void  a  concession 
agreement executed after the enactment of the Federal Concession Law, which was not preceded by a public bidding 
process.  There can be no assurance that future decisions by the Brazilian courts will interpret the concessions laws 
to allow municipalities to grant concessions without a public bidding process. 

The legislature of the City of São Paulo approved Law No. 13,670 of November 25, 2003, which regulates article 
148  and  the  sole  paragraph  of  article  149  of  the  Organic  Law  of  the  Municipality  of  the  City  of  São  Paulo, 
concerning water supply and sewage public services, establishes the Municipal Regulation System of Water Supply 
and  Sewage  Public  Services,  creates  the  Regulatory  Authority  for  Water  and  Sewage  Services  of  São  Paulo, 
addresses  its  organization  and  operation  and  establishes  the  Municipal  Sanitation  Plan.    Pursuant  to  this  Law,  the 
Mayor of the City of São Paulo has authority to grant and monitor formal concessions for water and sewage services 
in the Municipality of the City of São Paulo.  Following the enactment of Law No. 13,670, the Governor of the State 
has  filed  a  legal  action  alleging  that  the  Law  is  unconstitutional,  as  a  result  of  which,  the  enforcement  of  Law 
No. 13,670  had  been  suspended.    On  April  20,  2005,  the  court  ruled  in  favor  of  the  governor  of  the  State,  by  a 
majority of votes.  The City of São Paulo appealed the decision and a final judgement was still pending as of the 
date of this annual report. 

Public Consortiums Law 

On  April  6,  2005,  the  Brazilian  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  consortiums 
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.  
Considering  the  nature  of  the  services  rendered  by  us,  it  is  possible  that,  in  the  future,  the  Company  may  have 
interest and/or opportunity to contract in a manner provided for in this newly enacted law in order to regulate the 
relationship with some municipalities to which it renders basic sanitation services. 

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. 

45 

 
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  (“CORSANPA”)  to  provide  the  State  of  São  Paulo  with  a  more 
independent  regulatory  ability  in  relation  to  sanitation  services.  CORSANPA  will  be  directly  subordinated  to  the 
Secretary of Energy, Hydric Resources and Sanitation of the State of São Paulo. 

CORSANPA´s  responsibilities will  include, among  others, (i) the regulation and control of the  sanitation services 
for which the State is responsible, including monitoring the progress of our performance and the progress of dispute 
resolution  between  Sabesp  and  Sabesp’s  customers  (ii)  the  approval  of  agreements  entered  into  between  us  and 
municipalities (iii) carrying out studies for the creation of a regulatory agency for the sanitation sector and proposing 
legal  and  regulatory  measures,  as  applicable.  CORSANPA  will  also  propose  the  terms  of  cooperation  agreements 
between the State and municipalities to better regulate our relationship with the communities to which we currently 
provide services (or may intend to provide services in the future), but where the State has no granting authority.  

Public-Private Partnerships 

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

Payment  is  conditional  upon  performance.    The  payment  may  be  collected  through:  (i)  fares  paid  by  users;  (ii) 
assignment of credits belonging to the Public Administration, except taxes; and (iii) 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. 

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: 

• 

• 

• 

• 

• 

the purpose, duration and goals of the bid; 

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; 

46 

 
• 

• 

a combination of the criteria above; or 

the largest amount offered in consideration for the concession. 

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 
in order to develop the National System for Water Resources Management.  Under proposed legislation, the 
National Water Agency would be responsible for the coordination of the regulatory aspects involved in the 
rendering of water and sewage services.  See “—Pending Legislation” above. 

According to existing law, federal and state agencies are authorized to collect fees related to water usage from other 
governmental agencies under their jurisdictions.  In most cases, the fees have yet to be established by implementing 
regulations.    However,  for  two  specific  water  basins  (the  Rio  Paraíba  do  Sul  water  basin  and  the  Piracicaba, 
Capivari  and  Jundiaí  Rivers  water  basin),  water  usage  legislation  was  enacted  requiring  us  to  pay  the  Federal 
Government or an agency in respect of the use of water.  We started making payments in respect of the Rio Paraíba 
do Sul on March 2003. 

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: 

• 

• 

• 

• 

• 

• 

• 

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 (Agência Nacional de 
Águas—ANA) 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 
Department of Water and Energy of the State (Departamento de Águas e Energia Elétrica do Estado de São Paulo) 
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. 

47 

 
 
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 Department of Water and Energy (Departamento de Águas e Energia Elétrica) of the State 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  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 
Department of Water and Energy of the State.  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 

An  ordinance  issued  by  the  Ministry  of  Health  (Ministério  da  Saúde)  of  the  Brazilian  government  sets  forth  the 
standards of potability of all water for human consumption in Brazil.  This ordinance is modeled on the U.S. Safe 
Drinking  Water  Act  and  regulations  promulgated  by  the  U.S. Environmental  Protection  Agency  thereunder.    The 
Secretariat of Health (Secretaria de Estado da Saúde) of the State has also set minimum standards for the potability 
of water for human consumption which are more restrictive than the national rules and must be observed by us. 

We analyze test samples at our laboratories to determine compliance  with Ordinance No. 518, of March 25, 2004 
and  state  law  using  “Standard  Methods”  (181st.  Edition)  procedures  established  by  the  American  Water  Works 
Association.  A Presidential Decree enacted in 2005 determined that the disclosure of the water quality to consumers 
is compulsory. 

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,  or  CETESB  (Companhia  de  Tecnologia  de  Saneamento 
Ambiental), a State-controlled company controlled by 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 sludge treatment facilities 
and  other  pollution  sources.    Although  we  have  not  received  formal  authorization  from  CETESB  to  discharge 
untreated 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 untreated sewage into the River Tietê, a major river in the 
São  Paulo  Metropolitan  Region.    CETESB  participates  in  the  development  of  this  project.    There  can  be  no 

48 

 
assurance that we will  not be required in the future to obtain specific consents or authorizations for discharges of 
untreated 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 prejudice of us 
also having to comply with standards established by Federal legislation. 

State law also provides 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 such discharges, we cannot assure 
you that such 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 acknowledged the enforcement of any such 
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; 

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  water  resources, 
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  “Item  4. 
Information on the Company—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.  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). 

49 

 
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  upon  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 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  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 

the total amount of the contractual obligation 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  InterAmerican 
Development Bank or the Japan Bank for International Cooperation.  The Central Bank circular 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  circular  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. 

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,  2005,  we  owned  201  water 
treatment  facilities  and  58,000  kilometers  of  water  pipes  and  mains,  439  sewage  treatment  facilities  and  37,181 
kilometers of sewer lines, as well as 15 water quality 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 the Federal Government has guaranteed. 

As of December 31, 2005 the total net book value of our property, plant and equipment was R$14,116.1 million. 

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

Environmental Matters 

Our  water  and  sewage  operations  are  subject  to  stringent  Brazilian  federal,  state  and  local  laws  and  regulations 
relating to the protection of the environment as described under “Government Regulation” below. 

In  the  state  of  São  Paulo,  the  Environmental  Sanitation  Technology  Company  (Companhia  de  Tecnologia  de 
Saneamento  Ambiental—CETESB)  is  responsible  for  pollution  control  pursuant  to  State  Law  No. 997  of  May  31, 
1976.  In particular, the construction and operation of water and sewage treatment facilities, as well as the release of 
effluents  and  final  disposal  of  the  sludge  generated  as  a  result  of  the  water  and  sewage  treatment  process,  must 
comply  with environmental  standards established by  State environmental laws,  such  as State  Decree No. 8,468 of 
September 8, 1976, as amended. 

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 Brazilian 
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, studies 
are prepared by outside experts who make recommendations on measures designed to minimize the environmental 
consequences  of  a  project.    The  environmental  impact  report  is  then  submitted  to  governmental  authorities  for 
analysis  and  approval.    Once  the  environmental  impact  assessment  is  approved,  the  project  goes  through  a  three-
stage licensing process, which includes licenses: 

• 

• 

• 

Previous license—to define the exact location and scope of work; 

Installation license—to begin construction; and 

Operation license—to operate the facility. 

In order to obtain the environmental licensing of those undertakings that have a significant environmental impact, 
environmental agencies may impose on us an obligation to establish a nature conservation area.  In order to fulfill 
such 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  also  have  a  policy  of  implementing  programs  to  encourage  water 
conservation in order to minimize the environmental impact of our ongoing operations. 

In  order  to  improve  our  compliance  with  environmental  regulations,  since  1995,  we  have  maintained  a  division 
responsible  for  developing  environmental  impact  studies  and  programs.    It  is  also  our  policy  to  implement  water 
conservation programs in order to minimize the impact of our operations on our water supply.  We believe that we 
are in material compliance with all relevant environmental laws and regulations. 

Although our environmental compliance costs have not been substantial to date, we believe these costs will increase 
as water and sewage treatment capacity increases.  The amount and timing of future expenditures required to comply 
therewith could substantially increase from current levels. 

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,  2005,  we  had  paid  a  total  aggregate  amount  of  R$6.09 million  in 
premiums, covering approximately R$983.3 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.

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 22 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. 

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 19.0 million, the São Paulo Metropolitan Region accounted for approximately 
75.9%,  74.5%  and  75.5%  of  our  gross  revenue  from  sales  and  services  in  2003,  2004  and  2005,  respectively.  
Approximately 73.1% of the property, plant and equipment reflected on our balance sheet as of December 31, 2005 
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. 

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 

53 

 
• 

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%.    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.  We are currently 
evaluating and considering a potential revision to our tariff structure in order to improve our return on investment.  
Tariffs have historically been adjusted once a year and for periods of at least 12 months.  A study on this topic was 
finished in January 2006 and has been delivered to our executive committee and Board of Directors and the resulting 
recommendations  are  currently  being  detailed  for  implementation.    The  following  table  sets  forth,  for  the  periods 
indicated, the percentage increase of our tariffs, as compared to three inflation indices:

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.    Other  negative  economic  factors  in  2002 
included  the  continued  economic  and  political  uncertainties  in  Argentina  and  in  Venezuela,  concerns  over  the 
impact  of  the  conflict  in  the  Persian  Gulf  and  its  effects  on  the  price  of  oil  products  and  the  global 
economic slowdown. 

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  U.S.$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. 

54 

 
 
 
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. However, with the slow down of the economy and the consequent reduction of inflation rates, starting from 
November, the Central Bank has begun a process of reducing the base interest rate in order to encourage economy 
growth. On December 31, 2005, the base interest rate was 18%. 

In 2005, the real appreciated 13.4% as compared to the U.S. dollar and real gross domestic product grew by 2.4%. 
Despite  such  appreciation,  Brazil  had  a  commercial  surplus  of  U.S.$44.8  billion,  its  highest  commercial  surplus 
ever.  The  average  unemployment  rate  has  dropped  from  11.5%  to  9.8%  in  the  main  metropolitan  regions  of  the 
country, in accordance with unemployment estimates published by the IBGE. The inflation rate, as measured by the 
IGP-M, was 1.2% in 2005. 

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 increases our exposure to exchange rate movements as discussed below. 

The Central Bank increased the base interest rate to 26.5% on February 19, 2003 and decreased it to 16.0% on April 
14, 2004.  The Central Bank increased the base interest rate to 17.75% on December 15, 2004.  During the first four 
months of 2005, the Central Bank continued to raise the base interest rate, which reached 19.5% on April 20, 2005.  
However,  starting  from  November,  the  Central  Bank  has  begun  a  process  of  reducing  the  base  interest  rate.  On 
December 31, 2005, the base interest rate was 18%. 

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$1,576.0  million  as  of 
December 31, 2005.  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.

Effects of Drought 

Much of 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  impact  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. 

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 

56 

 
 
 
 
 
• 

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 
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.  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. 

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.  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. 

57 

 
As  of  December  31,  2005,  the  amounts  owed  to  us  by  the  State  for  the  provision  of  water  and  sewage  services 
included R$182.7  million which was considered overdue as of February 29, 2004.   As of  December 31, 2005 the 
State  owed  us  an  additional  R$111.5  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$672.7 million as of December 31, 2005 (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 
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, 2005, 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.  This decision was appealed by Mauá and is pending Appeal 
Court decision.  For more information, see “Item 8.  Financial 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, 

58 

 
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. 

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,  which  generally  do  not  exceed  the  contractual  terms  of  our 
concession agreements. 

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.    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. 

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  (“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 

59 

 
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$35.1 million (net of tax effects totaling R$18.1 million) was presented as “extraordinary 
item  net  of  income  tax  and  social  contribution”.    The  remaining  R$30.6 million  was  charged  to  cost  of  services 
rendered, general and administrative expenses and selling expenses.  Based on independent actuarial reports, as of 
December 31, 2005, our obligation under Plan G1 was R$329.8 million.  See note 12 to our financial statements. 

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.  See note 22 to our financial statements. 

We  are  currently  evaluating  the  possible  introduction  of  a  defined  contribution  plan  for  new  employees  and 
providing exiting 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 22 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 2003, 2004 and 2005.  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 2005, we used an expected rate of 
return  on  assets  assumption  of  12.06%,  which  is  expected  to  remain  the  same  for  2006.    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 

60 

 
merged to form a company.  These amounts are reimbursed to us by the State, as primary obligor.  However, these 
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. 

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.

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 for 2005 from 
R$4,397.1 million for 2004. 

Net revenue from sales and services relating to water services for 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% increased in volume of water distributed and invoiced in 2005; 

the  continuing  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%. 

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  revenues  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$137.0 million, or 6.1%, to R$2,390.4 million in 2005 from R$2,253.4 
million in 2004.  As a percentage of  net revenues  from sales and services, cost of sales and services decreased to 
48.3% in 2005 from 51.2% in 2004. 

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

• 

• 

an increased of R$48.2 million, or 6.0%, in payroll expenses and related charges, primarily due to 
annual  salary  adjustments  of  7.9%  that  came  into  effect  in  May  2005,  offset  in  part  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 to 651 connections per employee in 2005 from 626 in 2004; 

an increase  of  R$37.1  million, or  14.2% in outside services,  principally  due to a R$17.0 million 
increased  in  payments  for  maintenance  of  domestic  connections,  a  R$10.0 million  increase  in 

62 

 
 
 
 
network  maintenance,  a  R$3.6  million  increase  in  payments  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  security  service  costs.    The  network,  connection  and 
system  maintenance  costs  principally  related  to  our  “Global  Sourcing”  maintenance  and 
materials project  (Program  for  the  maintenance  of  the  water  distribution  and  sewage  collection 
systems in the São Paulo Metropolitan Region); 

an  increase  of  R$24.4  million,  or  6.1%,  in  power  costs,  principally  as  a  function  of  a  14.1% 
increase in average tariffs for captive consumers 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  electricity,  by  the  implementation  of  plans  to  improve  energy  efficiency,  and  by  the 
ending  of  the  additional  ECE  charge  for  emergency  electricity  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  network  maintenance,  a  R$4.4  increase  in  materials  for  domestic 
connection maintenance, an increase of R$2.8 million in vehicle fuel and lubricant expenses and a 
R$1.1 million increase in materials for network maintenance; 

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 
materials for treatment 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 of R$2.7 million in costs for coal to treat algae.

Gross Profit 

As  a  result  of  the  factors  discussed  above,  gross  profit  for  2005  increased  R$419.3  million,  or  19.6%,  to 
R$2,563.0 million  for  2005  from  R$2,143.7  million  for  2004.    As  a  percentage  of  net  revenues  from  sales  and 
services, gross profit increased to 51.7% in 2005 from 48.8% in 2004. 

Selling Expenses 

Selling expenses for 2005 increased R$35.4 million, or 7.0%, to R$537.9 million in 2005 from R$502.5 million in 
2004.  As a percentage of net revenues 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 outside 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 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  improved 
recoveries; 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%  discussed  above,  the  effect  of  which  was  mitigated  in  part  by  a 
reduction in the number of our employees. 

63 

 
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 electricity consumption to the Free Market 
where we are able to pay less for electricity than we were able to pay as “captive customers”; and 
more efficient use of water treatment materials. 

Administrative Expenses 

Administrative  expenses  for  2005  increased  by  R$21.9  million,  or  7.0%,  to  R$335.5  million  in  2005  from 
R$313.6 million  in  2004.    As  a  percentage  of  net  revenues  from  sales  and  services,  administrative  expenses 
decreased to 6.7% in 2005 from 7.1% in 2004. 

The increase in administrative expenses primarily reflected: 

• 

• 

• 

• 

an increase of R$12.4 million, or 20.4%, in provisions for judicial proceedings, resulting from new 
claims as to which losses are probable;  

an  increase  of  R$3.6,  or  14.2%,  in  tax  expenses,  principally  for  CPMF  Provision  Financial 
Transaction Tax, 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. 

Financial Expenses, Net 

Net  financial  expenses  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. 

Net  financial  expenses  for  2005  decreased  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 revenues form sales and services, net financial expenses 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 
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 U.S.$670 million in 2005 from U.S.$990 million in 2004; and 

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

Offset by: 

• 

• 

• 

an increase of $77.6 million in interest and other charges related to our real-denominated debt due 
to our 6th, 7th, and 8th issues of debentures in September of 2004 and March and June of 2005, 
respectively.  As of December 31, 2005 and 2004, the total amount of outstanding debentures was 
R$ 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 R$23.2 million, or 16.8%, to R$114.7 million in 2005 from R$137.9 million in 2004. 

The decrease in financial income was due 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. 

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

Income (Loss) from Operations 

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

Non-Operating Income (Expenses) 

Non-operating  expenses  for  2005  decreased  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. 

Income Tax and Social Contribution Tax 

Income tax and social contribution tax (including deferred taxes) for 2005 increased 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  benefits  pension  plan  (Plan  G1)  on  a  straight-line  basis  against  earnings  over  the  five  years  ending 
December 31, 2006. 

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

65 

 
Net Income (Loss) 

As a result of the factors discussed above, net income increased 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. 

2004 Compared to 2003 

Net Revenue from Sales and Services 

Net  revenue  from  sales  and  services  for  2004  increased  by  R$266.3 million,  or  6.5%,  to  R$4,397.1 million  from 
R$4,130.8 million for 2003. 

Net revenue from sales and services relating to water services for 2004 increased by R$122.8 million, or 5.1%, to 
R$2,541.0 million  from  R$2,418.2 million  for  2003.    This  increase  was  mainly  due  to  the  August  2003  tariff 
increase of 18.9% (and, to a lesser extent, the August 2004 tariff increase of 6.8%) and the increase in revenue due 
to  our  shift  from  wholesale  to  direct  distribution  and  improvements  in  billing  and  collection  for  water  services  in 
São Bernardo do Campo.  This increase was offset by a 4.1% decrease in volume of water distributed and invoiced 
in  2004,  resulting  from  our  campaign  to  reduce  water  consumption  throughout  the  period,  together  with,  from 
March 15,  2004,  the  effects  of  the  usage  reduction  discount  plan  which,  as  discussed  above,  lowered  usage, 
discounted the bill of consumers who lowered their usage, and shifted some households into lower tariff categories.  
Total discounts given to consumers under this plan amounted to R$74.1 million, which would otherwise have been 
recognized as revenue.  Although the usage reduction discount plan ended in September 2004, the impact of the plan 
on our results of operations, including lowered usage of water by consumers, continued throughout the year.  By the 
end of the year, however, the impact of the plan had begun to abate, and usage levels started to increase. 

Net revenue from sales and services relating to sewage services for 2004 increased by R$143.6 million, or 8.4%, to 
R$1,856.1 million  from  R$1,712.5 million  for  2003.    Volumes  of  sewage  increased  by  2.8%,  rising  in  the  fourth 
quarter  as  the  impact  of  our  water  usage  reduction  discount  plan  abated,  while  tariffs  increased  by  6.8%.  
Additionally, revenue received for the first time for sewage services provided in São Bernardo do Campo after the 
acquisition of that municipality’s water and sewage assets contributed to the increase in net revenue. 

Cost of Sales and Services 

Cost  of  sales  and  services  for  2004  increased  by  R$186.2 million,  or  9.0%,  to  R$2,253.4 million  from 
R$2,067.1 million  for  2003.    As  a  percentage  of  net  revenue  from  sales  and  services,  costs  of  sales  and  services 
increased to 51.2% for 2004 from 50.0% for 2003.  The increase was primarily due to the following factors: 

• 

• 

• 

an increase of R$75.6 million, or 23.5%, in  electric power costs; R$53.5 million of this increase 
was due to an approximately 17.5% increase in electricity tariffs and R$22.1 million was due to 
increased  provisions  for  electricity  costs  incurred  but  not  yet  measured  or  billed  by  the 
electricity company; 

an  increase  of  R$53.2 million,  or  25.7%  in  outside  services,  primarily  due  to  the  costs  of 
R$47.0 million  relating  to  the  implementation  of  our  “Global  Sourcing”  maintenance  and 
materials project, works resulting from the acquisition of the São Bernardo do Campo water and 
sewage  systems  in  the  amount  of  R$9.8 million,  and  maintenance  of  operational  systems  and 
security services; and 

an increase of R$31.0 million, or 5.7%, in depreciation and amortization expenses, principally due 
to recognition of sites under construction as permanent assets. 

66 

 
Gross Profit 

As a result of  the above factors, gross profit  for 2004 increased by R$80.1 million, or 3.9%, to R$2,143.7 million 
from R$2,063.6 million for 2003.  As a percentage of net revenue from sales and services, gross profit decreased to 
48.8% for 2004 from 50.0% for 2003. 

Selling Expenses 

Selling  expenses  for  2004  increased  by  R$205.0 million,  or  68.9%,  to  R$502.5 million  from  R$297.5 million  for 
2003.  As a percentage of net revenue from sales and services, selling expenses increased to 11.4% for 2004 from 
7.2% for 2003. 

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

• 

• 

• 

an increase of R$204.0 million in bad debts expenses, net of recoveries.  This increase in bad debt 
expenses was caused by a more rigorous collection of bad debts through increased legal actions.  
Because accounts receivable in amounts more than R$30,000 overdue for more than 360 days old 
are  not  generally  recognized  as  bad  debts  until  legal  action  is  taken,  our  decision  to  bring  more 
legal  actions  and  the  deterioration  in  the  condition  of  the  municipalities  that  buy  water  on  a 
wholesale basis significantly increased the amount of bad debts recognized in 2004.  Recoveries, 
which  offset  bad  debt  expenses,  decreased  from  R$195.5 million  in  2003  to  R$62.9 million  in 
2004.  A reversal of bad debt expenses in the amount of R$129.0 million, which was recorded in 
2003  upon  the  acquisition  of  the  São  Bernardo  do  Campo  sewage  and  water  systems,  had  no 
equivalent in 2004; 

an  increase  of  R$8.1 million,  or  21.4%  in  general  expenses,  due  to  an  increase  in  fees  for  bank 
collection services, and 

an increase  of  R$7.2 million,  or 5.5%, in payroll and related charges, primarily  resulting  from  a 
4.2% increase in salaries which took effect in May 2004 and a R$1.4 million bonus paid to certain 
employees in connection with financial performance. 

These increases were offset by the following: 

• 

a decrease of R$15.6 million, or 18.9%, in outside services, primarily for debt collection services.  
These services have been  temporarily suspended while we re-bid the contract for these services, 
and  consider  our  strategy  for  using  outside  contractors  for  collection  services.    This  decrease 
should therefore not be regarded as a trend.   

Administrative Expenses 

Administrative expenses for 2004 increased by R$59.5 million, or 23.4%, to R$313.6 million from R$254.1 million 
for  2003.    As  a  percentage  of  net  revenue  from  sales  and  services,  administrative  expenses  increased  to  7.1%  for 
2004 from 6.2% for 2003.  The increase in administrative expenses primarily reflected: 

• 

• 

an  increase  of  R$27.4 million,  or  696.5%,  in  payments  to  outside  contractors,  primarily 
advertising  agencies  in  connection  with  publicizing  the  water  usage  reduction  campaign,  and 
professional services in connection with the issuance of debentures in September 2004; and 

an  increase  of  R$25.5 million,  or  171.6%,  in  costs  for  the  implementation  of  our  geographic 
the  entire 
information 
municipality infrastructure.

Financial Expenses, Net 

Net  financial  expenses  consist  principally  of  interest  on  our  indebtedness,  foreign  exchange  losses  in  respect  of 
indebtedness and inflation-based indexation charges relating to 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. 

Net financial expenses for 2004 increased by R$157.2 million, or 45.4%, to R$503.7 million from R$346.5 million 
for 2003.  As a percentage of net revenue from sales and services, net financial expenses were 11.4% for 2004 and 
8.4%  for  2003.    Financial  expenses  decreased  by  R$15.3  million  while  financial  income  decreased  by 
R$170.4 million. 

Financial expenses decreased R$15.3 million, or 2.3%.   

The decrease in financial expenses was primarily due to: 

• 

• 

• 

• 

• 

• 

a decrease in provisions for judicial proceedings related to interest expenses of R$99.9 million due 
to  a  reduction  in  the  amounts  provisioned  with  respect  to  pending  litigation  with  suppliers  and 
construction companies; 

a decrease of R$74.5 million in interest and other charges relating to real-denominated debt due to 
lower interest rates; 

an indexation-based decrease of R$68.6 million in real-denominated debt; 

a decrease in  income  tax  on  remittances  abroad  in  the amount  of R$61.1 million, relating  to  the 
recovery of amounts previously paid; 

a  decrease  of  R$36.9 million  in  interest  and  other  charges  relating  to  foreign  currency-
denominated  debt  due  to  the  appreciation  of  the  real  against  the  foreign  currency  in  which  our 
non-real debt is denominated; and 

a  decrease  of  R$17.5 million  in  penalties  that  we  had  provided  for  with  respect  to  payment  of 
COFINS  and  PASEP,  resulting  from  our  participation  in  the  “Paes”  program,  whereby  such 
penalties were settled. 

The  decrease  in  financial  expenses  was  partially  offset  by  a  R$360.9  decrease  in  foreign  exchange  gain  in  2004 
compared to 2003, reflecting the effects on our foreign currency-denominated debt of  the appreciation of the real 
against the foreign currency in which our non-real debt is denominated during those periods.  In 2004, we recorded 
a foreign exchange gain of R$179.7 million, resulting from an 8.8% appreciation of the real against the U.S. dollar.  
In 2003, we recorded a foreign exchange gain of R$540.6 million resulting from a 22.3% appreciation of the real 
against the U.S. dollar. 

Financial income decreased R$170.3 million, or 54.7%, to R$141.0 million for 2004 from R$311.3 million for 2003, 
primarily due to: 

• 

• 

a  R$46.9  million  decrease  in  interest  income  from  R$70.0  million  in  2003  to  R$23.1  million  in 
2004.   This  decrease was  primarily due  to  a R$130.5  million decrease  in income  from  cash and 
cash equivalents as we reduced our cash balances by repaying outstanding debt; and 

a decrease in income from monetary variations of R$143.6 million, primarily reflecting acquisition 
of São Bernardo do Campo and the settlement of claims against the State in 2003; there were no 
significant events in 2004. 

68 

 
As of December 31, 2004, 62.0% of our debt was real-denominated, and 77.5% of such real-denominated debt was 
floating rate debt and indexed to take into account the effects of inflation. 

Income (Loss) From Operations 

As a result of the above factors (including, in particular, foreign exchange gains), income from operations for 2004 
decreased by R$341.6 million, or 29.3%, to R$823.9 million from R$1,165.5 million for 2003. 

Non-Operating Income (Expenses) 

Net  non-operating  expenses  for  2004  decreased  by  R$20.6 million,  or  37.8%,  to  R$33.9 million,  from 
R$54.5 million  for  2003.    In  both  periods,  most  of  such  expenses  consisted  of  losses  on  disposal  of  property  and 
write-offs  of  obsolete  and  other  non-productive  fixed  assets,  amounting  to  R$34.4 million  for  2004  and 
R$61.7 million for 2003. 

Income Tax and Social Contribution Tax 

Income tax and social contribution tax (including deferred taxes) for 2004 decreased by R$0.7 million, or 0.3%, to 
R$241.9 million  from  R$242.6 million  for  2003,  due  to  the  reduction  in  profit  before  income  tax  and  social 
contribution  tax,  that  amounted  to  R$790.0 million  for  2004,  compared  to  a  profit  of  R$1,111.1 million  for  2003.  
This reduction in profits was partially offset by the fact that we took advantage of the income tax benefit for interest 
on  shareholders  equity.    This  benefit  totaled  R$52.0 million  for  2004,  compared  to  R$171.4 million  for  2003, 
relating  to  interest  on  shareholders’  equity  declared  of  R$152.9  million  and  R$504.9  million  for  2004  and 
2003, respectively. 

For 2004 and 2003, the statutory composite tax rate was 34.0%. 

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  benefits  pension  plan  (Plan  G1)  on  a  straight-line  basis  against  earnings  over  the  five  years  ending 
December 31, 2006. 

As  permitted,  the  expense  is  presented  as  an  extraordinary  item  of  R$35.1 million  (net  of  tax  effects  of 
R$18.1 million) for 2003 and 2004. 

Net Income (Loss) 

As a result of the above factors, net income for 2004 decreased by R$320.3 million, or 38.4%, to R$513.0 million, 
compared to net income of R$833.3 million for 2003. 

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, 2005, we had 
R$280.2  million  of  cash  and  cash  equivalents.    Outstanding  short-term  debt  was  R$759.0  million  as  of 
December 31,  2005,  of  which  R$126.2  million  was  denominated  in  foreign  currency.    Long-term  debt  was 
R$5,905.2 million, of which R$1,449.8 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. 

69 

 
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$1,655.3  million  in  2003,  R$1,436.1  million  in  2004  and 
R$1,754.8 million in 2005. 

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

Debt Financing.  As of December 31, 2005, we had R$5,905.2 million in long-term debt outstanding (excluding the 
current portion of long-term debt), of which R$1,449.8 million consisted of foreign currency-denominated long-term 
debt.  We had outstanding short-term debt of approximately R$759.0 million as of December 31, 2005, representing 
the current portion of our long-term debt.   

As  of  December  31,  2005,  approximately  R$126.2  million  of  this  short-term  debt  was  denominated  in  foreign 
currencies.    Substantially  all  of  our  foreign  currency-denominated  debt  of  R$1,576.0  million  as  of  December 31, 
2005 was denominated in U.S. dollars or in baskets of foreign currencies. 

This debt consisted principally of: 

• 

• 

• 

U.S.$435.5 million (R$1,019.3 million) in loans from the Inter-American Development Bank; 

U.S.$6.4 million (R$15.1 million) in loans from the World Bank; and 

U.S.$225.0 million (R$526.7 million) in aggregate principal amount of 12% Notes due 2008 sold 
in the international capital markets. 

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. 

Our  outstanding  domestic  debt  was  approximately  R$5,088.3  million  as  of  December  31,  2005  and  consisted 
primarily of real-denominated loans from Federal and State-owned banks (in particular, Banco do Brasil S.A. and 
Caixa  Econômica  Federal)  and  debentures  issued  in  April  2001,  April  2002,  September  2004  and  March  and 
June 2005. 

In addition, we entered into a credit agreement on August 6, 2004 with the Japan Bank for International Cooperation 
(“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$422.8).  The first 
disbursements  under  this  loan  were  made  in  January  2006  and  at  May  2006,  the  amount  outstanding  under  this 
facility was R$5.4 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.  In addition, we are currently negotiating with BNDES and Caixa Econômica 
Federal for additional loans to finance portions of our capital expenditure program.   

On September 17, 2004, we filed with the CVM a securities shelf program through which we will be able to offer 
certain  debt  securities,  including  non-convertible  debentures  and  commercial  paper  up  to  an  aggregate  amount  of 
R$1.5  billion  over  the  following  two  years.    As  part  of  this  program,  we  issued  R$600.0  million  in  aggregate 
principal amount of debentures in September 2004 (our sixth issue), 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 will pay interest at the CDI rate plus 1.75% per year, 
and the debentures of the second in the amount of R$188.3 million and third series in the amount of R$179.9 million 
will  pay  interest  at  rates  of  IGP-M  plus  11.0%  per  year.    Under  this  securities  shelf  program  we  also  issued 
R$300.0 million  in  aggregate  principal  amount  of  debentures  in  March  2005  (our  seventh  issue),  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, will pay interest at the CDI rate 

70 

 
plus 1.5% per year, and the debentures of the second series, in the total amount of R$100.0 million, will pay interest 
at the rate of IGP-M plus 10.8% per year.  We also issued, under this securities shelf program, R$700.0 million in 
aggregate principal amount of debentures in June 2005 (our eighth issue), 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,  will  pay  interest  at  the  CDI  rate  plus  1.5%  per  year,  and  the 
debentures of the second series, in the total amount of R$350.0 million, will pay interest at the rate of IGP-M 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—TR) plus an agreed margin. 

The  following  table  sets  forth  information  on  our  outstanding  debt  as  of  December  31,  2005.    See  note  9  to  our

(1)  UPR  stands  for  Standard  Reference  Unit  (Unidade  Padrão  Referência)  and  is  equal  to  the  Daily  Government  Interest  Rate  (Taxa

(2)  Agreements  to  provide  up  to  aggregate  of  approximately  R$487.2  million  in  financing  for  our  capital  expenditure  program.    We  have 

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

We are subject to covenants under agreements evidencing or governing our outstanding indebtedness, including but 
not limited to those set forth in a loan agreement with the Inter-American Development Bank, the indenture relating 
to the 12.0% Notes due 2008.  Each of these agreements contains, among other provisions, limitations on our ability 
to incur debt.  The indenture relating to the 12.0% Notes due 2008 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  Indebtedness  to  Adjusted  Capitalization  (as  defined  therein)  is  greater  than  0.42x  or  (2) the  Debt  Service 
Coverage  Ratio  (as  defined  in  the  indentures)  is  less  than  2.50x.    These  ratios  are  calculated  using  financial 
statements prepared under the constant currency method (which is an accounting methodology that differs from the 
Brazilian  Corporate  Law  Method  and  that  incorporates  inflation  accounting  no  longer  commonly  used  in  Brazil).  
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.  As of December 31, 
2005,  our  ratio  of  Indebtedness  to  Adjusted  Capitalization  was  0.25x  and  our  Debt  Service  Coverage  Ratio  was 
3.14x, in each case as calculated in accordance with the above-mentioned indenture. 

Brazilian regulations provide that a state-owned company, such as ours, must, subject to some exceptions, use the 
proceeds  of  “external  credit  operations”  (i.e.,  foreign  currency  borrowings)  to  refinance  outstanding  financial 
obligations.    Until  so  used,  these  proceeds  must  be  deposited  as  directed  by  the  Central  Bank.    The  deposit 
requirement  does  not  apply  in  the  case  of  import  financing  and  financing  transactions  involving  multilateral  and 
official organizations, such as the Japan Bank for International Cooperation, 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, 2005 were as follows:

Based on actuarial estimates. Amounts payable in any specific year depend on unknown factors including life expectancy.  

We believe that we can service 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 9 to our financial statements. 

Capital  Expenditures.    Our  cash  disbursements  for  purchases  of  property,  plant  and  equipment  under  our  capital 
expenditure  program  totaled  approximately  R$660.4  million  in  2005  and  R$670.3  million  in  2004.    Our  capital 
expenditure program will require total expenditures of approximately R$4.8 billion in the period from 2006 through 
2010, including approximately R$960.0 million in 2006 and R$960.0 million in 2007. 

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.  

72 

 
 
 
 
 
These special payments totaled R$96.4 million in 2005, R$85.3 million in 2004 and R$87.1 million in 2003.  The 
State  is  required  to  reimburse  us  for  such  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$672.7  million  as  of  December  31,  2005.  As  of  December  31,  2004  and  2003  these  receivables  had  reached 
R$576.3 million and R$491.0 million respectively, and they were reclassified to 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.  

The December 2001 agreement discussed above provided that the legal advisors of the State Finance Secretariat of 
São Paulo 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.    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.  Under the December 2001 agreement, the original first 
payment was to be made in July 2002.   

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 another program called PAES, 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 11 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 2005, 2004 and 2003 were 
R$348.2 million, R$152.9 million and R$504.1 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.   

On  April  20,  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,  to  be  paid  within  60  days  after  our  2007  shareholders 
meeting to shareholders of record as of May 3 2006.  We are currently unable to determine the amount, if any, of the 
portion of these declared dividends that the State will apply to the curent 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 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. 

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 
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 in shareholders’ equity are recognized when the payments are declared, not 
when  they  are  paid,  within  60  days  of  the  following  annual  shareholders’  meeting.  In  April,  May  and  November 
2003 and January 2004, we declared interest on shareholders’ equity to be paid after our 2004 annual 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  annual  shareholders’  meeting.    In  April,  June,  October  and  December  of  2005,  we 
declared interest on shareholders’ equity to be paid within 60 days after our 2006 annual shareholders’ meeting.  In 
April 2006, we declared interest on shareholders’ equity in the amount of R$129.6 million, to be paid within 60 days 
after our 2007 annual shareholders’ meeting. 

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 (loss) in our statement of operations. 

Off-Balance Sheet Obligations 

We had no off-balance sheet obligations as of December 31, 2005, 2004 and 2003. 

U.S. GAAP Reconciliation  

Our  net  income  (loss)  in  accordance  with  the  Brazilian  Corporate  Law  Method  was  R$833.3 million  in  2003, 
R$513.0 million  in  2004  and  R$865.6  in  2005.    Under  U.S. GAAP,  we  would  have  reported  net  income  (loss)  of  
R$642.6 million in 2003, R$417.5 million in 2004 and R$791.2 in 2005. 

Our  shareholders’  equity  in  accordance  with  the  Brazilian  Corporate  Law  Method  totaled  R$7,576.9 million  at 
December 31, 2003, R$7,951.6 million at December 31, 2004 and R$8,482.5 million at December 31, 2005.  Under 
U.S. GAAP,  we  would  have  reported  shareholders’  equity  of  R$6,085.6 million  at  December  31,  2003, 
R$6,364.8 million at December 31, 2004 and R$6,821.4 million at December 2005. 

74 

 
The principal differences between the Brazilian Corporate Law Method and U.S. GAAP that affect our net income 
(loss) in 2003, 2004 and 2005, as well as shareholders’ equity at December 31, 2003, 2004 and 2005, 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; 

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

ITEM 6. 

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES 

Management 

Under our by-laws and the Brazilian Corporate Law, we are  managed by our Board of Directors, which currently 
consists of ten directors, and a Diretoria, or Executive Committee, which currently consists of six executive officers. 

As our majority 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 meeting of shareholders to serve renewable one-year terms.  Each member of our 
Board of  Directors  must  be  one  of our shareholders,  under  the 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  the  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 must be comprised of independent members. 

The  current  members  of  our  Board  of  Directors  were  elected  in  the  annual  shareholders’  meeting  held  on 
April 27, 2006,  except  for  Mr. Pallin,  who  was  elected  during  an  extraordinary  shareholders  meeting  held  on 
June 19,  2006.    The  tenure  of  the  directors  will  end  upon  the  election  of  the  new  members  at  the  annual 
shareholders’ meeting to be held on April, 2007.  Currently, we have four directors considered independent under 
the Novo Mercado rules. 

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 current members of our Board of Directors and their respective positions:

Executive Committee 

Our Executive Committee is composed of six executive officers appointed by our Board of Directors for renewable 
two-year  terms.    Our  executive  officers  are  responsible  for  all  matters  concerning  our  day-to-day  management 
and operations. 

Executive  Committee  meetings  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.    Members  of  our  Executive  Committee  have 
individual responsibilities established by our Board of Directors and our by-laws.  The terms of all current members 
of our Executive Committee will expire in May 2007. 

Audit Committee 

Our  by-laws  provides  for  an  Audit  Committee  to  be  comprised  of  three  Board  members,  who  shall  cumulatively 
comply with the requirements of (i) independence, (ii) technical expertise, and (iii) 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 members are responsible for all matters concerning accounting, internal accounting and audit. 

The  minimum  participation  required  from  each  member  of  the  Audit  Committee  is  thirty  hours  per  month.  The 
members shall exercise their roles for the same period as the corresponding term of office of the respective Board 
member,  or  until  otherwise  resolved  by  the  Shareholders'  General  Meeting  or  by  resolution  of  the  Board 
of Directors. 

At a board meeting held on June 26, 2006, the following members of the Board of Directors were elected to serve on 
our Audit Committee:

Corporate Governance Practices 

The  significant  differences  between  our  corporate  governance  practices  and  the  New  York  Stock  Exchange 
standards  can  be  found  on  our  website,  www.sabesp.com.br.    The  information  found  at  this  website  is  not 
incorporated by reference into this document. 

Compensation 

Pursuant to the 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, 2005, 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$2.1 million.  In addition, in 2005, the executive officers accrued pension benefits of approximately R$0.3 million, 
and we have set aside R$0.3 million with respect to such pension benefits.  The members of our Board of Directors 
did not receive any such benefits. 

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.  We do not have stock-option plans for our directors and executive officers. 

Employees 

At December 31, 2005, we had 17,448 full-time employees.  During 2005, we had an average of 474 trainees.

The  average  tenure  of  our  employees  is  approximately  14  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,  Baixada  Santista,  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.  Every year we negotiate collective bargaining agreements, which establish the 
level of compensation and other benefits of our employees. 

Our most recent collective bargaining agreements, which became effective on May 1, 2006 and will expire on April 
30,  2007,  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, 2007. 

We have experienced the following strikes in the last five years, none of which interrupted essential services:  a two-
day strike in December 1999, a five-day strike in January 2000, a two-day strike in June 2000, a one-day strike in 
September 2001, a one-day strike in November 2001, a two-day strike in June 2002, a two-day strike in May 2003,  
a two-day strike in May 2004, a three-day strike in June 2005 and a one-day strike in May 2006.  Under Brazilian 
law, our non-administrative employees are considered “essential employees” and therefore are limited in their right 
to strike. 

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$11.6 million  in  2003  and  R$10.3 million  in  2004  and  R$11.3 million  in  2005.    See  note 12  to  our  financial 
statements.  Based  on independent actuarial reports, as of  December 31, 2005, our  obligation under this plan  was 
R$329.8 million. 

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 we make to our 
pension plans may not exceed the contributions made by the beneficiaries of these plans. 

In  August  1996,  we  established  a  profit-sharing  plan  for  all  employees  who  have  been  employed  for  at  least  six 
months.    In  1999,  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, 

82 

 
 
 
 
 
 
 
 
 
 
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  such  authorization  every  year  since  2000  and 
therefore paid profit-sharing amounts to our employees during this period.  On October 2, 2000, we entered into a 
collective  bargaining  agreement  with  the  unions  that  represent  our  employees,  which  established  a  new  profit-
sharing plan  for all employees who have  been employed for at least three months.  Under the profit-sharing plan, 
we,  after  negotiations  with  the  employee  labor  unions,  set  annual  company-wide  and  business  unit-specific 
operational  and  financial  targets.    Payments  can  be  in  an  aggregate  amount  of  up  to  the  equivalent  of  our  total 
payroll  for  one  month  and  are  made  to  the  extent  of  achievement  of  such  targets.    In  the  past,  one-quarter  of  the 
profit-sharing  payments  was  made  to  the  extent  that  company-wide  targets  were  satisfied,  while  the  other  three-
quarters were made to the extent the business unit-specific targets were reached.  The profit-sharing payments were 
reduced,  on  a  pro  rata  basis,  if  the  targets  were  not  fully  satisfied  and  payments  were  made  semi-annually.    We 
recorded  profit-sharing  expenses  of  R$40.0 million  in  respect  of  2003,  R$40.3 million  in  respect  of  2004  and 
R$44.3 million in respect of 2005.  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.

Related Party Transactions 

Transactions with the State 

We have entered into extensive transactions with the State, which is our controlling shareholder, and we expect to 
continue to do so.  The State 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 reflect policies of the State that depend on decisions of elected officials or 
public servants and are accordingly subject to change.  They may be particularly open to reconsideration following 
State elections, which are next scheduled to be held in October 2006.  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$296.1 million  during  the  year  ended  December  31,  2005.    Our 
accounts receivable  from  the State  totaled  R$294.2 million  as of December  31, 2005.    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 our company, who provided service to us between our inception and 1974, when such 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.    During  2005,  we  made  payments  to  former  employees  of  R$96.4 million  in  respect  of 

84 

 
 
 
 
 
 
 
 
 
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$672.7  million as of  December 31,  2005.  
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  such  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,  in  an  aggregate  amount  equal  to 
R$1,215.6 million  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 us in respect of: 

• 

• 

water  and  sewage  services  we  provided  to  governmental  agencies,  State-owned  autonomous  entities  and 
foundations through December 1, 2001 in the amount of R$358.2 million; 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  our  company  in  the 
amount of R$320.6 million; as we did not reach an agreement regarding such amounts, a joint inquiry has 
commenced in order to ensure agreement between us and the State. 

As  a  result,  R$649.1 million  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—CPOS),  on  behalf  of  the  State,  and  an  independent  appraisal  firm  (ENGEVAL—
Engenharia  de  Avaliações),  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,  plus  6.0%  per  year,  starting  on  the  date  the  first 
installment becomes due. 

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 us of ownership of the Alto Tietê System reservoirs from 
the  State  Department  of  Water  and  Energy  of  the  State  would  be  illegal.    An  injunction  against  the  transfer  of 

85 

 
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  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 Appeals of the state of São 
Paulo (Tribunal de Justiça do Estado de 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  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, as discussed above.  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  the  Company  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.    The  Company  retained 
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 such 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  annual 
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 

86 

 
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,  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, to be paid 
within 60 days after our 2007 shareholders meeting to shareholders of record as of May 3 2006. 

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, 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 over shareholders' equity. The remaining amount of interest over shareholders' equity owed by us to 
the State, of R$113.8 was netted against accounts overdue after February 2004. 

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,  2005,  the  amounts  owed  to  us  by  the  State  for  the  provision  of  water  and  sewage  services 
included R$182.7 million, which was considered overdue as of February 29, 2004.  As of December 31, 2005 the 
State  owed  us  an  additional  R$111.5 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$672.7 million as of December 31, 2005 (R$320.6 million of which was acknowledged by the State 
in the December 2001 agreement with us 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 loss is 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.  

Investment of Liquid Assets 

Our  cash  and  cash  equivalents  invested  with  State  financial  institutions  in  short-term  securities  amounted  to 
R$242.0 million as of December 31, 2005. 

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 International Bank for Reconstruction and 
Development  in  the amount  of  U.S.$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 

87 

 
 
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  U.S.$37.0 million  of  this  loan,  which  loan 
amount  was  increased  to  U.S.$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 in the amount of R$60.5 million as collateral for this 
financing.  As of December 31, 2005 our outstanding debt relating to this loan was approximately U.S.$6.4 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 which totaled R$2,222.7 million 
as of December 31, 2005.  The Federal Government has guaranteed, and the State has provided a counter-guarantee, 
in  repsect  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 Japan Bank for International Cooperation 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$422.8 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.    In  addition,  we  are  currently  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  currently  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 such agreement by R$5.9 million. 

We have the right to draw water 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 during 2004 and R$11.3 million during 2005. 

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  such  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 

Labor Proceedings 

In  October  1989,  the  São  Paulo  Water,  Sewage  and  Environment  Service  Workers  Union  (Sindicato  dos 
Trabalhadores em Água Esgoto e Meio Ambiente de São Paulo—SINTAEMA) commenced a lawsuit, on behalf of 
our employees, against us in  the Labor Court (Justiça do  Trabalho), alleging that we  had violated Brazilian labor 
laws and collective bargaining contracts when we ceased making certain payments to 21,337 of our employees in 
1989.  Those payments related to previously mandated inflation-related index adjustments to such employees’ wages 
and salaries, which, due to a change in applicable law, we had ceased making.  In November 1995, the Labor Court 
issued a decision in favor of SINTAEMA, although it never ruled with respect to the amount of damages payable by 
us.  We appealed the decision of the Labor Court and in April 1997 lost the appeal.  We appealed this decision to the 
Superior Labor Court (Tribunal Superior do Trabalho) and the Superior Court ruled against us.  However, we filed a 
motion  to  vacate  (ação  rescisória),  seeking  the  annulment  of  the  Superior  Court  ruling  and  obtained  a  favorable 
decision.  SINTAEMA appealed this decision and the Supreme Court maintained the decision in our favour.  The 
proceeding was dismissed in January, 2006. 

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, which 
amounts to approximately R$5.6 million, 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 Superior Labor Court (Tribunal 
Superior do Trabalho).  We currently cannot predict the amount that we will be required to pay to SINTAEMA, but 
we do not believe that the final outcome of this matter will have a material adverse effect on our business, results of 
operations, financial condition or prospects. 

We are defendants in 1,841 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,  of  August  26,  1958.  
Approximately 40 of these plaintiffs are also seeking the same benefits in the civil courts.  In all cases, we claim that 
the State, and not us, is responsible for the payments due to the plaintiffs.  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 at the first instance 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 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. 

We  are  party  to  other  lawsuits  and  administrative  proceedings  involving  SINTAEMA  and  current  and  former 
employees.  We do not believe that any liabilities relating to these other lawsuits or administrative proceedings will 
have a material adverse effect on our business, results of operations, financial condition or prospects. 

As of December 31, 2005, we had established a provision totaling R$28.6 million with respect to potential damages 
in lawsuits and administrative proceedings involving present and former employees, including the lawsuit described 
in the preceding paragraphs, based on calculations made by our legal and human resources departments.

Tax Proceedings 

On  May  28,  1999,  we  filed  a  lawsuit  challenging  a  law  enacted  in  1998  that  expanded  the  definition  of  revenue 
subject to public service taxes (Programa de Formação de Patrimônio do Servidor Público—PASEP) and increased 
the  social  security  contribution  tax  (Contribuição  para  Financiamento  da  Seguridade  Social—COFINS)  rate.  
However,  in  July  2003,  we  withdrew  our  lawsuit  and  included  the  amounts  owing  under  this  lawsuit  and  the 
amounts  due  under  the  REFIS  program  (a  tax  recovery  program),  in  another  program  called  PAES,  which  is  an 
alternative  payment  plan  for  taxes  owed.    In  accordance  with  the  PAES  tax  recovery  program,  we  are  paying 
amounts  subject  to  the  settlement  agreement  in  120  monthly  installments,  which  began  in  July  2003.    As  of 
December 31, 2005, the amount due under the PAES program was R$295.5 million. 

We initiated legal action in July 1999 to challenge the creation by the Municipality of 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 Appeals of the state of São Paulo (Tribunal de Justiça do Estado de 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 injunction seeking the suspension of the tax assessment by the municipality.  The injunction was granted 
on first instance and maintained in the decision of the lower courts.  The municipality has appealed this decision to 
the  court  of appeals 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 will be 
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 water and sewage services.  Our 
request for an injunction against the municipality was granted by the trial court of the state of São Paulo (11a. Vara 
da Fazenda Pública do Estado de São Paulo), and such injunction was maintained after the filing of an appeal by 
the municipality.  However, on May 5 2005, the lower court issued a decision against us and revoked the injunction 
granted in our favour.  We appealed such decision and are trying to maintain the effects of the injunction until a trial 
decision in this legal proceeding is issued.  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$108.1  million,  was 
assessed  by  our  tax  advisors  as  being  a  possible  loss,  accordingly,  no  provision  has  been  recorded,  in  case  the 
decision of the lower court is upheld.   

In November 2004, we took legal action against the Municipality of Bragança Paulista against the imposition of a 
new charge over 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 collection of any current or future amounts due in respect of this change until 
there is  a final decision  on the  merits.   On  June  2005, the  lower  court  ruled  in  our  favour and the  injunction  was 
maintained.  The municipality appealed such decision and as of the date of this annual report, a trial decision was 
still pending. 

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 through to our customers by increasing tariffs 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 

91 

 
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  party  to  many  lawsuits  related  to 
compensation awards.  As of December 31, 2005, we estimated that we will be required to make payments totaling 
R$279.6 million  with  respect  to  all  condemnation  matters.    We  do  not  believe  that  the  pending  condemnation 
proceedings  will,  individually  or  in  the  aggregate,  have  a  material  adverse  effect  on  our  business,  results  of 
operations, financial condition or prospects. 

Other Legal Proceedings 

We are 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$70.1 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.  Although we are not able to predict the final outcome of the lawsuits, we believe that they will 
not have a material adverse effect on our business, results of operations, financial condition or prospects. 

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 Appeals 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,  and  we  can  give  no  assurance  that  the  ultimate  determination  will  be 
favorable to us.  Despite the pending lawsuit, we continue to provide water and sewage services to Santos. 

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

In addition, we are party to a number of proceedings with the Public Prosecution Office 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  Supreme 
Court has confirmed the understanding that we have the right to charge a tariff for the sewage services we provide.  
We do not believe that the final outcome of these proceedings will have a material adverse effect on our business, 
results of operations, financial condition or prospects. 

We are 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 such municipalities and that we failed to make certain 
investments  in  sewage  treatment  systems  as  provided  in  the  relevant  concession  agreements.    In  addition,  we  are 
being  sued  by  the  Public  Prosecution  Office  of  the  state  of  São  Paulo  as  well  as  some  non-governmental 
organizations  through  a  number  of  environmental  civil  public  actions  (i) aiming  to  enjoin  us  from  releasing 
untreated  sewage  into  certain  local  water  courses,  and,  in  some  of  them,  (ii) seeking  remedies  for  environmental 
damages,  which  have  not  yet  been  specified  and  evaluated  by  technical  experts  of  the  courts;  and  (iii) 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 thereto.  In our response to these lawsuits we emphasize that the installation and operation 
of sewage treatment facilities in those locations is included in our business plan and that the immediate cessation of 
the  release  of  untreated  sewage  into  the  relevant  local  water  courses  would  hinder  us  from  collecting  sewage  –  a 
primary necessity – in those locations, causing much more damages against the environment and public health.  In 
most of these lawsuits, no final judicial decision has been reached by local judges, yet.  Although we are not able to 
predict the final outcome of these lawsuits, we believe that such outcome, if unfavorable to us, may have a material 
adverse effect on our business, results of operations, financial condition or prospects. 

Among those aforementioned civil public lawsuits are the following:  (A) The Public Prosecution Office of the State 
has  brought  a  civil  public  action  before  the  São  Bernardo  do  Campo  Court  (5a.  Vara  Cível  de  São Bernardo  do 

92 

 
Campo) which seeks 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 
enviromental  recovery  project.    A  judge  issued  a  preliminary  order  that  we  immediately  cease  such  dumping  and 
established a daily R$50,000 fine for not complying with such order; however, this order has been suspended at our 
request.  Although the lower court has issued a decision in our favor, the Public Prosecution Office of the State of 
São  Paulo  has  appealed  such  ruling.  As  a  result,  the  upper  courts  decided  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 caused. This decision is not yet  final.   We currently are unable to 
evaluate the extent or cost of any remedy that we may be held responsible for in connection with this matter; (B) the 
Public Prosecution Office of the State of São Paulo has brought a civil public action before the Paraguaçu Paulista 
Courts of Law (1a. Vara de Paraguaçu Paulista) which seeks reparation for and cessation of environmental damage 
allegedly  caused  by  our  release  of  raw  sewage  into  the  Alegre  River,  situated  in  the  Municipality  of  Paraguaçu 
Paulista.  The lower court has issued a decision against us, requiring that we (i) cease the release of raw sewage into 
the Alegre River, (ii) invest in a water and sewage treatment facility in the Municipality of Paraguaçu Paulista; and 
(iii) pay an administrative penalty in the amount of R$116.9 million for environmental damage.  The decision also 
imposes a daily penalty if we fail to comply with numbers (i) and (ii) above.  We have appealed this decision and 
such decision will not be effective until a final ruling is issued on this appeal; (C) 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.  We presented our defense in January 2004, 
alleging that the plaintiff has no standing to bring this action and that some of the requests are inconsistent and/or 
impossible.    We  also  explained  that  the  water  collection  limit  was  duly  authorized  by  law  and  by  the  competent 
governmental agency, and that the plaintiff did not prove or specify the damages.  The injunction was not granted, 
and  this  action  is  now  awaiting  judgment  on  the  first  instance;  and  (D)  on  February 25,  2003,  a  request  for  a 
preliminary  injunction  was  filed  against  us,  restricting  us  from  disposing  of  sewage  without  due  treatment,  in  the 
municipality of Lutécia.  The injunction also determined 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  system  of  the 
municipality, in addition to paying a daily fine in the amount of R$300,000 (1000 minimum salaries) in the event the 
case is decided against us.  After submission of an expert report, the Public Prosecutor Office requested that we be 
sentenced to pay the amount of R$82.8 million. In anticipation of a settlement with the Public Prosecutor Office, we 
condemned the area and requested the respective environmental licenses for it. 

We are also party to several administrative proceedings with CETESB – Companhia de Tecnologia de Saneamento 
Ambiental (Environmental Sanitation Technology Company) seeking the imposition of penalties for environmental 
damages  allegedly  caused  by  us  and  other  regulatory  matters.    However,  we  do  not  believe  that  the  final 
determination  in  these  proceedings  will,  individually  or  in  the  aggregate,  have  a  material  adverse  effect  on  our 
business, results of operations, financial condition or prospects. 

Certain  construction  service  contractors  have  filed  claims  in  court  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,  2005,  we  established  a  provision  for  these  claims  in  the  amount  of 
R$194.4 million to meet probable losses arising from unfavorable decisions in these actions. 

Approximately 930 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,  2005,  we  have  established  a  provision  in  the  amount  of 
R$279.5 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.  However, we do not believe that the final determinations in these 
matters will, individually or in the aggregate, have a material adverse effect on our business, results of operations, 
financial condition or prospects.

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 such decision.  Notwithstanding these legal proceedings, 
we have reduced to 2.0% the penalty fee we charge on late bill payments by all of our customers.  Although we are 
not able to predict the final outcome of these lawsuits, we believe that they will not have a material adverse effect on 
our business, results of operations, financial condition or prospects. 

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 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 of the State 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, with respect 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 Appeals of the state of São Paulo (Tribunal de 
Justiça  do  Estado  de  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. 

In  December  1996,  we  commenced  legal  action  to  collect  payment  due  from  Diadema.    The  lower  courts  have 
issued  a  decision  against  us  and  in  November  2000  we  appealed  this  decision.    In  December  2005  the  Court  of 
Appeals  ruled  in  our  favour  and  declared  our  agreeement  valid.    This  legal  action  was  followed  by  several  other 
related legal proceedings, some of which are currently pending.  A class action suit and an annulment action have 
been  decided  with  favourable  results  for  us.    We  entered  into  a  settlement  agreement  with  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  systems.    However,  to  date  Mauá  has  not  yet  made  any  payments  to  us  under  the  settlement 
agreement.    We  commenced  legal  action  in  December  1996  against  Mauá  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 
SAINA–Saneamento  Básico  do  Município  de  Mauá  appealed  this  decision.    Diadema  and  Mauá  are  currently 
operating their own water and sewage systems, and we are supplying them with water on a wholesale basis.  As of 
December 31, 2005, both Diadema and Mauá were in arrears with respect to amounts owed to us for water sold on a 
wholesale basis prior to 1997, as well as for a portion of water sold since 1997. 

On March 25, 2004, the Public Attorney’s Office filed a civil action against the Municipality of the City 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 agreement we entered into with the Municipality of the 
City of Itapira.  Although an injunction was granted, the São Paulo state Court of Appeals has stayed the injunction.  
On March 23, 2005, the House of Representatives of Itapira approved a decree revoking the concession agreement.  
In addition, Municipal Law No. 3,730/05 was enacted revoking an earlier law which authorized the municipality to 
enter  into  the  concession  agreement  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. 

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, but it is still subject to appeal. 

The Municipality of Sandovalina has brought a legal action against  us seeking to (i) obtain the termination of the 
concession entered into with us and (ii) 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 

94 

 
have  responded  with  a  counterclaim  against  the  municipality  for  payment  of  R$115,400  related  to  the  supply  of 
water  from  December  1999  to  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  systems  of 
Sandovalina, and the lawsuit is still in the fact-finding phase. 

On  April 11,  2003,  we  entered  into  an  agreement  with  the  Labor  Public  Attorney’s  office  called  the  Termo  de 
Ajustamento de Conduta, or TAC.  Under this special agreement, we agreed to ensure that no construction work is 
performed on our behalf by third parties using unregistered employees or without complying with safety regulations.  
The  agreement  provides  for  a  daily  R$1,000  fine  for  non-compliance  with  these  obligations.    The  fine  applies  to 
each worker laboring under irregular conditions or each clause under default, as the case may be.  The agreement is 
enforceable by the Brazilian labor courts and is valid indefinitely. 

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  include  the  following:  (A) a 
preliminary proceeding (ação cautelar) started by the Municipality of Guariba seeking a court order requiring us to 
exhibit  documents  in  order  to  instruct  an  account  revision  proceeding;  (B) the  Municipality  of  Ribeirão  Pires  has 
proposed  preliminary  proceedings  seeking  the  exhibition  of  documents  to  inspect  the  services  which  we  provide; 
(C) the  Municipalities  of  Itupeva  and  Monte  Mor  have  proposed  proceedings  seeking  to  obtain  a  court  order  to 
require  us  to  exhibit  documents  and  information  in  order  to  evaluate  the  possibility  of  renewal  of  our 
concession agreement. 

We  are  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 and do  not believe  that such proceedings  will,  individually  or in the 
aggregate, have a material adverse effect on our business, results of operations, financial condition or prospects. 

Industrial and Intellectual Property 

Trademarks 

We have secured registration of the Sabesp design and composite trademark at the Brazilian Institute of Industrial 
Property (Instituto Nacional da Propriedade Industrial—INPI).  We have also filed applications with the INPI for 
registration  of 
trademarks  “ÁGUA—VIDA—CONFORTO—SAÚDE,”  “SABESFÉRTIL,”  “PURA—
PROGRAMA  DE  USO  RACIONAL  DA  ÁGUA”  and  “HORA  H—SABESP,”  which  are  still  under  examination 
and are pending a final decision. 

the 

Patents 

We have a patent granted by INPI covering a differential pressure gauge with digital reading.  We have also filed a 
patent  application  to  cover  an  engine-powered  starting  system  to  automatically  correct  product  dosage  in 
conventional dispensers by gravity and have other pending applications at the INPI. 

Software 

We use software systems to manage our activities which we have acquired from vendors.  We have also developed 
certain computer programs for management and control of water and sewage treatment plants, as well as for third-
party services management, called “AQUALOG,” “SGL” and “Electronic Price Quotation” (Cotação Eletrônica de 
Preços), and have secured registration of these programs at the INPI and the agency of trademarks.  AQUALOG is 
the only Brazilian software designed to monitor water treatment.  SGL (Bid Management System) is an electronic

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 the Brazilian corporation 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 the Brazilian corporation 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 

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,  2005,  the  balance  of  our  legal  reserve  was  R$215.3 million,  which  was  equal  to  6.3%  of  our 
paid-in capital. 

The  Brazilian  corporation  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 the Brazilian corporation 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  the  Brazilian  corporation  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, 2005, we had an investment reserve of R$2,255.0 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 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 Corporate Law Method. 

Mandatory Distribution 

The Brazilian corporation 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 

96 

 
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.    The  Brazilian  corporation  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 the Brazilian corporation 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 the Brazilian corporation 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,  are  able  to  have  dividends,  sales  proceeds  or  other  amounts  with  respect  to  these  shares  eligible  to  be 
remitted outside Brazil.  See “Item 10.  Additional Information—Regulation of Foreign Investment”. 

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. Additional Information—Regulation 
of  Foreign  Investment”.    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. 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: 

97 

 
• 

• 

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. 
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. 

The following table sets forth the distributions out of net income that we made or will make to our shareholders in 
respect of our 2003, 2004 and 2005 net income.  All these amounts distributed or to be distributed were or will be in 
the form of interest on shareholders’ equity.

On April 28, June 23, October 20 and December 15, 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, 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, to be paid within 60 days after our 2007 shareholders’ meeting. 

Dividend Policy 

We  intend  to  declare  and  pay  dividends  and/or  interest  on  shareholders’  equity,  as  required  by  the  Brazilian 
corporation 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.

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 an online system connected to 
traditional  and  internet  brokers  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. 

In order to better control  volatility, the São Paulo Stock  Exchange adopted a “circuit breaker” system pursuant to 
which trading sessions may be suspended for a period of 30 minutes or one hour whenever the 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, 2005, the aggregate market capitalization of the 381 companies listed on the São Paulo 
Stock Exchange was equivalent to approximately US$482.1 billion and the 10 largest companies listed on the São 
Paulo Stock Exchange represented approximately 51.5% 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, 2005, 
we  accounted  for  approximately  0.40%  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.  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; 

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 the Brazilian 
corporation  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 the Brazilian corporation 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. Additional Information—Regulation of 
Foreign Investment”.

ITEM 10.  ADDITIONAL INFORMATION 

The following is a summary of the material terms of our common shares, including related provisions of our by-laws 
and the Brazilian corporation 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 the 
Brazilian corporation law.  As set forth in Article 2 of our by-laws, our corporate purpose is to plan, provide, and 
operate and market basic sanitation services throughout the territory of the state of São Paulo, including the capture, 
collection, processing and distribution of water, as well as the collection, removal and final disposal of sewage and 
sludge.  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.  The 
Brazilian  corporation  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  the  Brazilian  corporation  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. 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 
some circumstances that may result in a change in the rights of shareholders, such as the creation of preferred shares, 
the 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.    The  Brazilian  corporate  law  specifies  other 
circumstances where the dissenting shareholder may also have appraisal rights. 

According to the Brazilian corporation 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  the  Brazilian 
corporation 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 

103 

 
• 

the right to withdraw from the company in the cases specified in the Brazilian corporation law. 

Pursuant to the Brazilian corporation 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 the Brazilian corporation 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  the  Brazilian  corporation  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  the  Brazilian corporation 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 
the Brazilian corporation 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 
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. Key 
Information—Risk  Factors—Risks  Relating  to  Our  Common  Shares  and  ADSs—A  holder  might  be  unable  to 
exercise preemptive rights with respect to the common shares underlying our ADSs”. 

Redemption and Rights of Withdrawal 

The Brazilian corporation 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 the Brazilian corporation law; 

104 

 
• 

• 

• 

• 

• 

• 

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

to change our corporate purpose; 

to split up, subject to the conditions set forth in the Brazilian corporation 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 the Brazilian 
corporation 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.  The Brazilian corporation 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 the Brazilian corporation 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. 

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  “—Market  Information”  above.    Under  our  by-laws,  any  disputes  among  us,  our 
shareholders and our  management with  respect to the  application  of Novo Mercado rules, the 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. 

105 

 
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 the Brazilian corporation 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 the Brazilian corporation 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. Directors, Senior Management and Employees”. 

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”. 

Regulation of Foreign Investment 

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 
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. 

106 

 
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.  Key  Information—Risk  Factors—Risks  Relating  to  Our  Common  Shares  and  ADSs—If  a  holder 
exchanges  ADSs  for  common  shares,  he  or  she  risks  losing  the  ability  to  remit  foreign  currency  abroad  and 
Brazilian tax advantages” and “—Taxation—Brazilian Tax Considerations” below. 

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 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 foreign, 
state or local tax laws. 

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”). 

107 

 
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. 

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 (i) is not a 2,689 holder, or (ii) 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. 

108 

 
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 Transactions (“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 
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 (i) the public offering is registered with the CVM and (ii) 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 (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. 

109 

 
Tax on Bonds and Securities Transactions (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 Taxation 

The 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 is: 

• 

• 

• 

• 

a citizen or resident of the United States; 

a corporation or partnership 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,  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 (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 different from those discussed 
below.  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. 

110 

 
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,  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 the balance in excess of adjusted basis will be taxed 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  (i)  specified  holding  period 
requirements are met, (ii) 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,  (iii)  the  company 
paying the  dividend  is a  “qualified  foreign  corporation” and (iv) 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.  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.  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 (i) has held common shares or 
ADSs for less than a specific minimum period during which it is not protected from risk of loss or (ii) 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  depending  upon  the  holding  period  of  such  capital  assets.  

111 

 
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. 

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. 

Documents on display 

We are subject to the periodic reporting and other informational requirements of the U.S. Securities Exchange Act of 
1934, as amended.  Accordingly, we are required to file reports and other information with the U.S. Securities and 
Exchange Commission.  You may inspect and copy reports and other information filed by us at the public reference 
facilities maintained by the Commission at 450 Fifth Street, N.W, Washington D.C. 20549.  You may obtain copies 
of  these  materials upon written  request  from  the Public Reference Section  of the Commission at 450  Fifth Street, 
N.W, Washington D.C. 20549 at prescribed rates.  You may also inspect this material at the offices of the New York 
Stock Exchange, Inc., 20 Broad Street, New York, New York 10005.  In addition to the public reference facilities 
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, 
New York, New York 10286. 

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 

At  December  31,  2005  and  2004,  approximately  R$1,576.0  million  and  R$2,680.9  million,  or  23.7%  and  38.0%, 
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, 2005 and 2004 from each hypothetical instantaneous and unfavorable 
1% change in the U.S. dollar against the real would have been approximately R$15.8 million and R$26.8 million, 
respectively.    Consistent  with  these  estimates,  a  hypothetical  instantaneous  and  unfavorable  10%  change  in  this 
exchange rate would have resulted in losses of approximately R$157.6 million and R$268.1 million as of December 
31,  2005  and  2004,  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, 2005 were as follows: 

Devaluation (appreciation) of real in relation to: 
     U.S. dollar ...........................................................................................................................  
     World Bank basket of currencies ........................................................................................  
     Inter-American Development Bank basket of currencies...................................................

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. 

At  December  31,  2005  and  2004,  we  had  no  short-term  debt  outstanding,  other  than  the  current  portion  of  long-
term debt. 

Interest Rate Risk 

At  December  31,  2005  and  2004,  approximately  R$2,726.7  million,  or  53.6%,  and  R$2,853.1  million,  or  65.3%, 
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,  2005  and  2004,  approximately 
R$1,116.4  million, or 21.9%, and R$802.4 million, or 18.4%, 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).  At December 31, 2005 and 2004, R$901.8 million and 
R$1,055.8 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. 

At December 31, 2005 and 2004, 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 

113 

 
 
 
 
government.    We  invest  these  excess  funds,  which  totaled  R$155.7  million  on  December  31,  2005  and 
R$55.9 million  on  December  31,  2004,  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$11.2 million and 
R$8.0  million  if  a  hypothetical  instantaneous  and  unfavorable  change  of  100  basis  points  in  the  interest  rates 
applicable to financial liabilities on December 31,2005 and 2004, 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$111.6 million and R$80.2 million as of December 31, 2005 and 
2004, 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,  2005.    For  the  foreign  currency 
denominated obligations these amounts have been converted at the selling rates at December 31, 2005, and do not 
represent amounts which may actually be payable with respect to such obligations on the dates indicated.

(a) 

(b) 

Based  on  their  evaluation  as  of  the  end  of  the  period  covered  by  this  annual  report,  the  chief  executive 
officer  and  the  chief  financial  officer  of  Sabesp  have  concluded  that  as  of  such  date  Sabesp’s  disclosure 
controls and procedures (as defined in Rules 13a-15(c) and 15d-15(c) under the U.S. Securities Exchange 
Act of 1934, or “Exchange Act”) are effective to ensure that information required to be disclosed by Sabesp 
in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported 
within the time periods specified in Securities and Exchange Commission rules and forms. 

During the year ended December 31, 2005, Sabesp has been implementing changes to its internal controls 
and accounting procedures in preparation for certain internal control reporting requirements as set forth in 
Section 404 of the Sarbanes-Oxley Act. 

ITEM 16A.  AUDIT COMMITTEE FINANCIAL EXPERT 

At a board meeting held on June 26, 2006, we established an audit committee, as defined under section 3(a)(58) of 
the Exchange Act.  Our Board of Directors has determined that Farrer Jonathan Paul Lascelles Pallin qualifies as an 
“audit committee financial expert” as defined for the purposes of this Item 16A in Item 16A of Form 20-F.  Farrer 
Jonathan Paul Lascelles Pallin is an “independent director” within the meaning of the SEC rules.  

ITEM 16B.  CODE OF ETHICS 

We have adopted a code of business conduct and ethics, as defined in Item 16B of Form 20-F under the Securities 
Exchange Act of 1934, as amended. Our code of business conduct and ethics, called Code of Ethics and Conduct, 
applies  to  all  employees  of  the  company,  including  the  company’s  directors,  principal  executive  officer,  principal 
financial officer and principal accounting officer. Our Code of Ethics and Conduct is available on  our web site at

(1)  Audit Fees are the fees billed by Deloitte Touche Tohmatsu Auditores Independentes for the fiscal year 2003, for the audit of our annual 
financial  statements,  reviews  of  interim  financial  statements  and  attestation  services  that  are  provided  in  connection  with  statutory  and 
regulatory filings or engagements. 

(2)  Audit-related  Fees  consist of  fees  billed  for  assurance  and  related  services  that  are  reasonably related  to  the  performance of  the audit  or 
review  of  the  Company’s  financial  statements  or  that  are  traditionally  performed  by  the  external  auditor,  and  include  consultations 
concerning  financial  and  tax  accounting,  and  reporting  standards;  internal  control  reviews;  review  of  security  controls  and  operational 
effectiveness of systems; and employee benefit plan audits. 

Pre-approval policies and procedures 

Pursuant to Brazilian law, our Board of Directors is responsible, among  other  matters, for the selection, dismissal 
and oversight of the external auditor.  Our management is required to obtain the Board of Directors’ approval before 
engaging independent auditors to provide any audit or permitted non-audit services to us.  The Brazilian Federal and 
State  Public  Bidding  Laws  also  apply  to  us  with  respect  to  obtaining  services  from  third  parties  for  our  business, 
including  the  services  provided  by  our  independent  external  auditor.    As  part  of  the  bidding  process,  the  external 
independent  auditing  firms  are  required  to  submit  proposals,  and  are  then  selected  by  us  based  on  certain  criteria 
including technical expertise and cost. 

During 2005, 2004 and 2003, Deloitte Touche Tohmatsu did not provide non-audit services to us.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Shareholders and Management of 
Companhia de Saneamento Básico do Estado de São Paulo - SABESP 
São Paulo - SP 

1.  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,  2005  and  2004,  and  the  related  statements  of  income,  changes  in  shareholders’ 
equity  and  changes  in  financial  position  for  each  of  the  three  years  in  the  year  ended  December 
31,  2005.  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. 

2.  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. The Company is not required to have, nor were we engaged to perform, an audit of 
its  internal  control  over  financial  reporting.  Our  audits  included  consideration  of  internal  control 
over  financial  reporting  as  a  basis  for  designing  audit  procedures  that  are  appropriate  in  the 
circumstances  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the 
Company’s  internal  control  over  financial  reporting.  Accordingly,  we  express  no  such  opinion.  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. 

3. 

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, 2005 and 2004, and the results of its operations, changes in shareholders’ equity and changes 
in  financial  position  for  each  of  the  three  years  in  the  year  ended  December  31,  2005,  in 
conformity with accounting practices adopted in Brazil. 

4.  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. 

5.  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  year  ended  December  31,  2005  and  the 
determination  of  shareholders’  equity  as  of  December  31,  2005  and  2004,  to  the  extent 
summarized in Note 22 to the financial statements.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

1. 

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  368  municipalities  in  the  State  of  São 
Paulo, nearly all of which  are through concessions granted by the municipalities and most of 
them with 30-year term. Out of the 17 (seventeen) concession contracts that expired in 2005, 
8 (eight) have been extended for a period from 3 (three) months to 1 (one) year and 9 (nine) 
are under negotiation with the respective Municipalities. In 2006, 135 contracts will expire and 
the  rest  between  2007  and  2034.  Management  expects  that  the  referred  concessions  will  be 
renewed  or  extended,  thus  there  will  not be  an  interruption of  the  water  supply  and  sewage 
collection.  The  net  book  value  of  property,  plant  and  equipment  items  relating  to  the 
municipalities where the concessions which were under negotiation at December 31, 2005 or 
that will expire in 2006, totals R$ 1.57 billion and net revenue totals R$ 700,0 million related 
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 a substantial portion of the sales and services rendered. 
In  Santos,  a  municipality  located  in  the  Santos  Coastal  Area,  which  also  has  a  large 
population,  the  Company  operates  under  a  public  authorization,  like  in  some  other 
municipalities in the Santos Coastal Area and the Ribeira Valley, where the Company started 
operating after the merger of the companies that formed SABESP.  Management believes that 
the Company has a vested right to provide water and sewage services in these municipalities 
based  upon,  among  other  things,  its  ownership  of  the  related  water  and  sewage  systems 
serving  the  City  of  São  Paulo  and  these  other  municipalities  and  certain  succession  rights 
resulting from the merger which formed the Company. 

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  regarding  concession  areas,  number  of  municipalities,  volumes  of  water  and 
sewage  and  other  related  data  disclosed  in  this  report that  do not  arise  from  the  accounting 
and/or financial statements are unaudited.

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

2. 

PRESENTATION OF 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 operations. 

(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. 

3. 

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 22 for further discussion of 
the differences between BR CL and US GAAP and the reconciliation of shareholders’ equity and 
net income (loss) 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) 

Revenue from sales and services 

Revenue for water and sewer services is recognized as water is consumed or as services are 
provided.  Revenue  from  water  and  sewer  services  rendered  but  not  billed  is  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 18). 

(b) 

Marketing costs 

Marketing costs are generally expensed as incurred and reported in administrative expenses. 
Marketing costs were R$ 17,861, R$ 31,615 and R$ 4,206 for the years ended December 31,

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

2005, 2004 and 2003, respectively. No marketing costs were deferred at December 31, 2005 
and 2004.  

(c) 

Financial income and expenses 

Financial  income  and  expenses  are  primarily  comprised  of  interest  and  monetary  and 
exchange variations on loans and financing and financial investments, and are calculated and 
reported on the accrual basis of accounting. 

(d) 

Income and social contribution taxes 

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 tax is 
calculated at the rate of 9%. These taxes are reported on an accrual basis. 

Deferred taxes related to tax loss carryforwards and temporary differences are calculated and 
recorded based on future taxable or deductible amounts 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 tax liability (non-
cash) 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 are comprised primarily of 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  an  original  maturity  of  90  days  or  less.  These  comprise 
mainly Financial Investment Funds (FIF’s). Foreign currency deposits, if any, are translated at 
balance  sheet  date  exchange  rates.  The  Company  is  required  by  law  to  invest  excess  cash 
with financial institutions controlled by the State Government (see Note 5). 

(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. 

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. 

(h) 

Inventories 

Inventories  of  materials  used  in  operations  and  in  the  maintenance  of  the  Company’s  water 
and sewage systems are stated at the lower of average acquisition cost or realizable value and

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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 and 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  &  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. 

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  utilities, 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

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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. 

Concession assets acquired 

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.  

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.  

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) 

Deferred charges 

Deferred  charges  are  comprised  primarily  of  deferred  project  costs  and  technical  studies, 
which  are  being  amortized  using  the  straight-line  method  over  5  years  from  the  date  when

(l) 

Loans and financing 

Loans and financing are  adjusted by indexation charges and foreign exchange variations and 
include  accruals  for  related  interest  expense.  Loans  and  financing  denominated  in  foreign 
currencies are translated to reais using the exchange rate in effect at the balance sheet date.

(m) 

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. 

(n) 

Provisions for contingencies 

Provisions  for  contingencies  are  recorded  at  the  estimated  amounts to  cover  potential  losses 
related  on  labor,  tax,  civil,  commercial,  environmental  and  other  claims  and  lawsuits,  at 
administrative  and  court  levels,  when  such  losses  are  considered  probable  and  are 
estimateable by management. 

(o) 

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 estimatable by Management. 

(p) 

Pension and postretirement benefits 

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.  

(q) 

Interest on shareholders’ equity 

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 15). 

(r) 

Use of estimates 

The  preparation  of  financial  statements  requires  management  to  make  estimates  and 
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  the  reported 
amounts of revenues and expenses for the reporting periods. Actual results could differ from 
those estimates. 

(s) 

Earnings (loss) per share 

Earnings  per  share  is  calculated  based  on  the  number  of  shares  outstanding  at  the  balance 
sheet date.

(iii)    Agreements  –  renegotiation  of  past-due  balances  [from  non-government  controlled 
companies] into installments. Contractual indexation and interest on renegotiated installments 
recognized  financial  income  were  R$ 61,353,  R$ 53,531,  and  R$ 31,687  in  2005,  2004  and 
2003, respectively. The amounts under agreements are generally due in approximately 6 – 12

balances  of  wholesale  customers-municipal  authorities  for  which  management  believes 
collection  is  not  likely  within  the  next  year.  A  number  of  wholesale  customers  have  been 
contesting certain tariffs since mid-1998 and are not paying the amounts disputed. While such 
amounts  are  currently  due  and  payable,  management  believes  that  based  on  the  historical 
settlement  and  payment  history,  that  such  amounts  are  better  classified  as  long-term.  The 
long-term  portion  is  recorded  net  of  an  allowance  for  doubtful  accounts  of  R$ 519,632  and 
R$ 394,569 at December 31, 2005 and 2004, respectively.

Campo,  which  were  reversed  in  connection  with  the  concession  agreement  reached  in 
December 2003. 

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. 

Management believes that the allowance for doubtful accounts is sufficient to absorb probable 
losses in customer accounts receivable 

(e) 

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.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

(ii) 

Reimbursement for pension and benefits paid. 

Reimbursement  for  pension  and  benefits  paid  represents  supplementary  pension  and  leave 
benefit paid by the Company on behalf of the State Government 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,  2005  and  2004,  2,761  and  2,770  retirees, 
respectively,  received  supplementary  pension  payments,  for  which  the  Company  paid 
R$ 96,388  and  R$ 85,340  in  2005  and  2004,  respectively.  There  were  189 active  employees 
at December 31, 2005, who will be entitled to these benefits once they retire, as compared to 
211 at December 31, 2004. 

(iii) GESP Agreement 

On December 11, 2001, the Company entered into an agreement with the State of São Paulo 
Government (the GESP Agreement), 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.  Pursuant  to  the  GESP  Agreement,  the  State 
Government,  by  force  of  Law  No.  200/74,  acknowledged  to  be  responsible  for  the 
supplemental  retirement  and  pension  benefits  and  agreed  to  pay  amounts  it  owed  to  the 
Company  in  respect  of  water  and  sewage  services.  The  value  at  the  date  of  the  Agreement 
was  R$ 678,830,  of  which  R$ 320,623  refered  to  supplemental  retirement  and  pension 
benefits  in  the  period  from  March  1986  until  November  2001,  and  R$ 358,207  refered  to 
water  supply  and  sewage  collection  services  invoiced  and  due  from  1985  until  December  1, 
2001. 

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 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.

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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.   

As these negotiations are still in the early stages, 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. 

The  following  summarizes  activity  with  respect  to  amounts  due  from  the  State  Government 
related to the reimbursement of pension and retirement benefits:

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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’ 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,  of  R$ 581,779, 
including monetary adjustments based on the  Referential Rate (TR) at the end of each  fiscal 
year  through  February  2004.  In  addition,  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 payable relating 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  payable 
relating to 2003 (R$ 360,667). 

The  Company  and  the  State  Government  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  is  being  paid  in  monthly  installments  from  May  2005  through  May  2009, 
which  is  subject  to  monthly  monetary  adjustment  at  the  Expanded  Consumer  Price  Index 
(IPCA/IBGE), plus 0.5%. 

As  the  right  of  offset  was  contemplated  in  the  original  terms  of  the  GESP  Agreement,  the 
Company recorded the applicable effects of such Amendment as of and through December 31, 
2003,  including  the  monetary  adjustments  of  both  amounts  payable  to  and  receivable  from 
the State Government. In addition, the amounts payable to the State Government for interest 
on  shareholders’  equity  specifically  identified  in  the  agreement  for  reciprocal  offset  through 
2004 have been reclassified as a reduction of amounts receivable at December 31, 2004. 

The balance of Interests on Own Capital, in the amount of R$ 113,842, adjusted pursuant to 
the IPCA-IBGE, was netted against accounts overdue after February 2004. 

During  2005,  the  Company  received  the  amount  of  R$ 35,797  relating  to  the  payment 
installments from May to December 2005 and has offset the remaining balance of interest on 
shareholders’  equity  due  the  State  Government  of  R$ 105,520  against  the  balance  due  for 
water and sewage services as contemplated in the Amendment. 

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.

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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$ 58,397  and  R$ 61,135  of  amounts  capitalized  with  respect  to  these  agreements,  net  of 
accumulated depreciation, at December 31, 2005 and 2004, respectively. 

(d) 
Program of Rational Use of Water 

Contracts with reduced Fare for State and Municipal Public Entities that adhere to the 

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. 

(e) 

Guarantees 

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. 

7. 

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 the Company’s water and sewage service concessions in 1995. As of December 
31, 2005, this asset amounted to R$ 148,794. 

Under  these  concession  agreements,  the  Company  invested  in  the  construction  of  water  and 
sewage  systems  in  these  municipalities  to  meet  its  concession  service  commitments.    Upon 
the  unilateral  termination  of  the  Diadema  and  Mauá  concessions,  these  assets  were 
impounded  by  the  municipal  authorities,  which  took  on  the  responsibility  of  providing  water 
and  sewage  services  in  these  areas.  At  that  time,  the  Company  reclassified  from  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 the Company had contractually agreed 
as fair compensation with the relevant authorities.   The net book value of items of property, 
plant  and  equipment  items  relating  to  the  municipality  of  Diadema,  which  was  written-off  in 
December 1996, was R$ 75,231, and the balance of indemnity and other receivables from the

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

local government was R$ 62,876 at December 31, 2005. The net book value of property, plant 
and equipment items relating to the municipality of Mauá, which was written-off in fiscal year 
1999, was R$ 103,763, and the balance of the indemnity receivable from the municipality was 
R$ 85,918 at December 31,2005. 

The  Company’s  rights  to  the  recovery  of  these  amounts  are  being  disputed  by  the 
municipalities and no amounts have been received to date.   

In December 1996, the Company filed a claim seeking compensation for the amounts due by 
the  municipality  of  Diadema.  In  the  first  instance,  the  judge  pronounced  a  sentence  against 
the  Company.  The  Company  filed  an  appeal  in  November  2000 and on  December  1st,  2005, 
partial acceptance to the appeal was given in order to declare the validation of the agreement 
with the Municipality of Diadema. 

With respect to Mauá, a decision has been issued by the lower court requiring Mauá to pay an 
amount  of  R$ 153.2  million  as  compensation  for  the  loss  of  profits.    This  decision  was 
appealed by Mauá and is pending Appeal Court decision. 

Based on the advice of legal counsel, management continues to believe that the Company has 
the  legal  right  to  receive  such  amounts  and  it  continues  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.

Disposals of property, plant and equipment 

The  Company  wrote  off  property,  plant  and  equipment  items  in  the  amount  R$ 19,051, 
R$ 34,616  and  R$ 61,654  in  2005,  2004  and  2003,  respectively.  Of  these  losses,  R$ 9,879, 
R$ 26,034 and R$ 49,379 in 2005, 2004 and 2003, respectively, related to the disposal, theft 
and obsolescence of assets in use. The remaining balance of losses, of R$ 9,172, R$ 8,582 and 
R$ 12,275  in  2005,  2004  and  2003,  repectively,  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.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

(d)  

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  in 
conformity with applicable legislation. 

Disbursements  to  be  effected  as  from  fiscal  year  2006  are  estimated  to  be  approximately 
R$ 279,621 (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. The total amount paid relating to expropriations of property, plant 
and equipment in 2005 and 2004 was R$ 11,472 and R$ 5,423, respectively. 

(e) 

Assets in guarantee 

At  December  31,  2005  and  2004,  the  Company  had  assets  in  the  amount  of  R$ 249,034 
provided as guarantee under the Special Tax Debt Refinancing Program - PAES (Note 11). 

Three of the Company’s properties in the amount of R$ 60,539 were pledged as collateral for 
the financing with the International Bank for Reconstruction and Development. 

(f) 

Non-operating assets 

The  Company  had  R$  31,832  at  December  31,  2005  (2004  -  R$  31,903)    referring  to  other 
non-operating assets, comprised primarily of land surrounding reservoirs. 

(g) 

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. 

(h) 

Totally depreciated assets 

On December 31, 2005 and 2004 the gross accounting value of the totally depreciated assets 
which are still in use is R$ 336,086 and R$ 307,078, respectively. 

(i) 

(i) 

Concessions 

Intangible Assets 

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

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, 2005 and 2004 would have 
been  R$ 461,068  and R$ 491,475, respectively. In  the years  ended  on  December 31, 2005 and 
2004, the realized revaluation reserve amounts were R$ 89,449 and R$ 104,500.

(b) Pension benefits 

Managed by Fundação Sabesp de Seguridade Social – “SABESPREV”, the defined benefit pension 
plan is supported by monthly contributions as follows: 2.10% from the Company and 2.19% from 
the  participating  employees.  In  order  to  meet  the  provisions  of  CVM  Resolution  No.  371,  of 
December  13,  2000,  below  is  a  description  of  the  amounts  of  pension  and  retirement  benefits 
paid granted and payable, to which the employees will be entitled after their service time. 

Based on independent actuarial reports at December 31, 2005, calculated in conformity with the 
Projected  Unit  Credit  Method,  the  Company  had  a  net  actuarial  liability  of  R$  329,772  (R$ 
328,605  in  2004),  representing  the  difference  between  the  present  value  of  the  Company’s 
benefit obligations to the participating employees, retired employees, and pensioners, and the fair 
value of the related assets, as shown below:

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.

For  the  2005  actuarial  assessment,  the  general  mortality  table  has  been  changed  to  GAM-83  in 
replacement  to  the  adjusted  IBGE  table,  as  the  GAM-83  table  reflects  the  increase  in  life 
expectancy of the population evaluated. 

The  number  of  active  participants  at  December  31,  2005  and  2004  was  16,449  and  16,673, 
respectively. The number of inactive participants at December 31, 2005 and 2004 was  4,881 and 
4,908, 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,  2005  is  R$ 
456,861 (2004 – R$ 357,378). The 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$ 266,074 at December 31, 2001 over five years using the straight-line method beginning

The Sponsor and the “SABESPREV” are in process of negotiation so that the technical deficit may

Contribution Plan. The Management estimates not incurring in additional costs resulting from any 
potential change of the referred plans.

PROFIT SHARING 

The  Company  recorded  additional  salary  and  payroll  charges  in  the  amounts  of  R$ 44,292, 
R$ 40,262, and R$ 39,978 for the years ended December 31, 2005, 2004 and 2003, respectively, 
relating to employees profit sharing, in accordance with the labor legislation and agreements with 
trade  unions.  Such  agreements  define  certain  targets  to  be  met  and  also  define  limits  for 
distribution per employee based on monthly salaries.  These charges represent an estimate made 
by  management,  as  the  final  determination  of  the  amounts  payable  is  not  yet  available  at  the 
date of the preparation of the financial statements.   

As  a  result  of  negotiations  held  by  the  Company  with  entities  representing  the  employees,  a 
Profit  Sharing  Program  was  implemented  for  the  period  from  July  2005  to  June  2006,  with  the 
payment of an amount corresponding to up to one month’s payroll, depending on achievement of 
defined  targets.  In  December  2005  the  Company  made  an  advance  payment  of  R$ 22,906, 
equivalent  to  50%  of  one  month’s  payroll.  The  remainder  of  the  2005  accrual,  if  applicable,  is 
estimated to be paid at the end of August 2006.

Provisions for contingencies 

The Company is party to a number of claims and legal proceedings arising in the normal course 
of  business,  including  civil,  labor,  environmental,  tax  and  other  matters.  The  Company  has 
recorded provisions for those claims and assessments whose risk of loss has been determined by 
management, based on the advice of the Company’s legal and tax advisors, as probable and for 
which  amounts  are  estimable.  These  recorded  provisions,  by  nature  of  the  related  cases,  are 
summarized below as of December 31:

held by the court, pending final resolution of the matters. 

(d) Summary of claims and assessments 

(i) 

Customer claims 

Approximatly  930  customer  claims  have  been  filed  against  the  Company  by  commercial 
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 whose risk of loss has been assessed as probable. 

Out of the R$ 728,900 for which the Company has assessed the likelihood of loss as possible, an 
estimated  amount  of  R$ 103,000  (including  claims  for  refunds,  monetary  adjustment,  interest 
and  attorney’s  fees)  relates  to  new  lawsuits,  and  approximately  R$ 186,200  refers  to  thirteen 
lawsuits.  At  December  31,  2005,  the  lower  court’s  decisions  on  four  of  these  lawsuits  were  still 
pending. While the lower courts have ruled in favor of the Company in connection with other nine 
lawsuits, a final decision is still pending in all nine cases.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

(ii) 

Contractor claims 

Certain  construction  service  contractors  have  filled  claims  in  court  alleging  underpayment  of 
monetary  adjustments,  withholding  of  amounts  relating  to  the  effects  of  the  Real  Plan  and 
monetary  losses  from  economic-financial  imbalance  in  the  applicable  contracts.  These  lawsuits 
are  in  progress  in  several  different  court  levels,  and  provisions  are  recorded  for  cases  with 
probable chance of loss. 

Out of the amount of R$ 178,700 for which  we have assessed the likelihood of loss as possible, 
approximately R$ 140,600 refers to four lawsuits. At December, 31, 2005, three of these lawsuits 
were in their respective initial stages and one had been ruled in favor of the Company, but was 
still pending final judgment by the appellate court. 

(iii) 

 Civil and Tax claims 

The  Company  is  party  to  a  number  of  civil  claims  related  to  indemnifications  for  material 
damages, pain and suffering and loss of profits allegedly caused to third parties and which have 
been brought before different court levels. In addition, the Company is party to a number of tax 
proceedings.  At December 31, 2005, provisions have been recorded in the amount of R$74,510 
for civil and tax claims for which the risk of loss has been assessed as probable. 

The  Company  is  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$70.1  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.    The 
Company  has  assessed  the  risk  of  loss  related  to  these  cases  as  remote,  and  as  such,  no 
amounts have been provisioned at December 31, 2005. 

In November 2004, the Company took legal action against the Municipality of Bragança Paulista 
against the imposition of a new charge over the use of public areas  for the installation of water 
and  sewage  mains  related  to  the  public  sanitation  services  provided  to  the  municipality.    In 
February 2005, the Company was granted an injunction suspending the imposition of this charge 
and preventing the municipality from collection of any current or future  amounts due in respect 
of this change until there is a final decision on the merits of the case.  In June 2005, the lower 
court  ruled  in  Company’s  favor  and  the  injunction  was  maintained.    The  municipality  appealed 
such decision and a trial decision was still pending. 

The  Company  initiated  legal  action  in  July  1999  to  challenge  the  creation  by  the  Municipality  of 
City  of  São  Paulo  of  a  tax  on  the  use  of  public  areas.    The  tax  would  apply  to  the  Company’s 
water  and  sewage  mains  and  other  installations  located  in  public  areas.  Based  on  the  advice  of 
internal  legal  counsel,  the  Company  believes  that  this  municipal  tax  is  unlawful  because  it  was 
established  by  a  municipal  decree  instead  of  a  municipal  statute.  The  Company  is  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.  The Company has appealed the trial court decision to the 
Court  of  Appeals  of  the  state  of  São  Paulo  (Tribunal  de  Justiça  do  Estado  de  São  Paulo).    A 
recently approved law enacted the tax on the 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 tax  assessment 
by the municipality.  The injunction was granted on first instance and maintained in the decision 
of  the  lower  courts.    The  municipality  has  appealed  this  decision  to  the  court  of  appeals  of  the 
state of São Paulo and the decision is still pending.  The Company has assessed the risk of loss as 
possible and currently cannot estimate the potential increase in its expenses if it were required to

pay  this  tax  or  if  any  future  assessment of  this  tax  would  be  retroactive  to  1999.    To  date,  the 
Company  has  not  established  a  provision  for  any  potential  expense  arising  from  this  municipal 
tax. 

The Company has also taken legal action to challenge a City of São Paulo municipal law enacted 
in 2002 that revoked the Company’s blanket exemption from municipal taxes. As a result of the 
loss  of  the  exemption  from  municipal  taxes,  the  Company  may  be  subject  to  a  tax  on  services 
charged  at  a  rate  of  5.0%  on  gross  revenue  from  water  and  sewage  services.  The  Company 
requested an injunction against the municipality, which was granted by the trial court of the state 
of  São  Paulo  (11a.  Vara  da  Fazenda  Pública  do  Estado  de  São  Paulo),  and  such  injunction  was 
maintained after the filing of an appeal by the municipality. However, on May 5, 2005, the lower 
court  issued  a  decision  against  the  Company.  The  Company  intends  to  appeal  such  decision  to 
the  fullest  extent  permissible  by  law.    This  action,  for  which  potential  expense  amounts  to 
approximately R$ 108,095, is assessed as of possible loss by the Company’s tax advisors. 

In  2005,  new  actions,  whose  risk  of  loss  has  been  assessed  as  possible,  were  filed  in  the 
approximate  amount  of  R$ 117,000,  with  monetary  adjustment  to  the  lawsuits  in  course  of 
approximately R$ 59,000. 

(iv) 

Labor claims 

The Company is party to a number of labor claims and proceedings, at various legal stages and in 
a  number  of  courts,  brought  by  São  Paulo  Water,  Sewage  and  Environment  Service  Workers 
Union (Sindicato dos Trabalhadores em Água Esgoto e Meio Ambiente de São Paulo—SINTAEMA) 
and  the  Company’s  current  and  former  employees  related  to  overtime  pay,  health  hazard, 
premium  claims,  prior  notice  period,  job  deviation,  salary  parity,  and  other  benefits  among 
others.  At  December  31,  2005,  the  Company  had  recorded  provisions  totaling  R$28,576  with 
respect  to  potential  damages  in  lawsuits  and  administrative  proceedings  whose  risk  of  loss  has 
been determined as probable. 

On  January  9,  1990,  SINTAEMA  initiated  a  lawsuit  against  the  Company,  alleging  that  it  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  the  Company,  but  did  not  award  damages  to  SINTAEMA  at  that 
time. The Company and SINTAEMA are currently engaged in negotiations concerning the amount 
to be paid by it. The Company also filed a writ of mandamus seeking a court decision establishing 
that the penalty imposed against us, amounting to approximately R$ 5,558, is excessive since it 
exceeds  the  principal  amount  by  a  large  margin.  The  Company’s  request  was  denied  by  the 
courts and the lawsuit is now awaiting a final decision at Superior Labor Court (Tribunal Superior 
do Trabalho). 

The Company is also a defendant in approximately 1,841 labor proceedings and in one civil public 
action  initiated  by  and  on  behalf  of  some  of  the  Company’s  current  and  former  employees 
relating to certain benefits awarded by Law No. 4,819, of August 26, 1958. Approximately 40 of 
these plaintiffs are also seeking the same benefits in the civil courts.  In all cases, the Company 
claims  that  the  State  Government  is  responsible  for  the  payments  due  to  the  plaintiffs.    Some 
labor  and  civil  proceedings  have  been  ruled  upon  by  the  lower  courts,  but  no  final  decision  has 
been  issued  to  date  in  any  of  these  legal  proceedings.    An  injunction  was  granted  at  the  first 
instance in the civil public action to compel the Company to pay the benefits awarded by Law No. 
4,819 to all plaintiffs in that lawsuit. To date, the Company and the State Government have not 
agreed on any amounts to be reimbursed.  The civil public action is now awaiting decision on the 
merits of the case.

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

In  October  1989,  the  São  Paulo  Water,  Sewage  and  Environment  Service  Workers  Union 
(Sindicato  dos  Trabalhadores  em  Água  Esgoto  e  Meio  Ambiente  de  São  Paulo—SINTAEMA) 
commenced  a  lawsuit  against  the  Company  on  behalf  of  employees,  alleging  that  the  Company 
had  violated  Brazilian  labor  laws  and  collective  bargaining  contracts  when  it  ceased  making 
certain payments to 21,337 employees in 1989.  Those payments related to previously mandated 
inflation-related  index  adjustments  to  such  employees’  wages  and  salaries,  which,  due  to  a 
change in applicable law, the Company had ceased making.  In November 1995, the Labor Court 
issued  a  decision  in  favor  of  SINTAEMA,  although  it  never  ruled  with  respect  to  the  amount  of 
damages payable by the Company.  The Company appealed the decision of the Labor Court and 
in  April  1997  lost  the  appeal.    The  Company  later  appealed  this  decision  to  the  Superior  Labor 
Court  (Tribunal  Superior  do  Trabalho)  and  the  Superior  Court  ruled  against  it.  However,  the 
Company filed a motion to vacate (ação rescisória), seeking the annulment of the Superior Court 
ruling  and  obtained  a  favorable  decision.    SINTAEMA  appealed  this  decision  and  the  Supreme 
Court maintained the decision in the Company’s favor.  The proceeding was dismissed in January 
2006. 

(v)      Environment claims 

Environmental  claims  refer  to  several  administrative  proceedings  brought  by  municipalities  and 
other public agencies, including Companhia de Tecnologia de Saneamento Ambiental – “CETESB” 
(Environment  Sanitation  Technology  Company),  seeking  to  impose  fines  and  penalties    for 
alleged environmental damages. 

The Company is being sued by the Public Prosecution Office of the State of São Paulo as well as 
some non-governmental organizations through a number of environmental civil public actions (i) 
aiming to enjoin the Company from releasing untreated sewage into certain local water courses, 
and, in some of them, (ii) seeking remedies for environmental damages, which have not yet been 
specified  and  evaluated  by  technical  experts  of  the  courts;  and  (iii)  aiming  to  require  the 
Company to install and operate sewage treatment facilities in those locations.  In each case, the 
Company is or may be subject to daily fines for noncompliance thereto.  In its response to these 
lawsuits,  the  Company  emphasizes  that  the  installation  and  operation  of  sewage  treatment 
facilities in those locations is included in its business plan and that the immediate cessation of the 
release of untreated sewage into the relevant local water courses would hinder it from collecting 
sewage  in  those  locations,  causing  much  more  damages  against  the  environment  and  public 
health. In most of these lawsuits, no final judicial decision has been reached by local judges. 

Among those aforementioned civil public lawsuits are the following:   

The  Public  Prosecution  Office  of  the  State  has  brought  a  civil  public  action  before  the  São 
Bernardo do Campo Court (5a. Vara Cível de São Bernardo do Campo) which seeks reparation for 
environmental  damage  caused  by  the  Company  dumping  sludge  from  its  water  treatment 
facilities  into  certain  receiving  waters,  the  immediate  cessation  of  this  practice  and  the 
implementation  of  an  environmental  recovery  project.    A  judge  issued  a  preliminary  order  that 
the  Company  immediately  cease  such  dumping  and  established  a  daily  R$50  fine  for  not 
complying with such order; however, this order has been suspended at the Company’s request.  
Although  the  lower  court  has  issued  a  decision  in  the  Company’s  favor,  the  Public  Prosecution 
Office  of  the  State  of  São  Paulo  has  appealed  such  ruling.    As  a  result,  the  upper  courts  have 
decided against the Company and have ordered it to stop dumping sludge within a year from the 
date the decision is considered final, or to pay a daily penalty of R$10, in addition to repairing the 
environmental damage caused.  This decision is not yet final.  The Company is currently unable 
to  evaluate  the  extent  or  cost  of  any  remedy  that  it  may  be  held  responsible  for  in  connection 
with this matter, whose risk of loss has been assessed as possible.

The Public Prosecution Office of the State of São Paulo has brought a civil public action before the 
Paraguaçu  Paulista  Courts  of  Law  (1a.  Vara  de  Paraguaçu  Paulista)  which  seeks  reparation  for 
and  cessation  of  environmental  damage  allegedly  caused  by  the  Company’s  release  of  raw 
sewage into the Alegre River, situated in the Municipality of Paraguaçu Paulista.  The lower court 
has issued a decision against the Company, requiring that it (i) cease the release of raw sewage 
into  the  Alegre  River,  (ii)  invest  in  a  water  and  sewage  treatment  facility  in  the  Municipality  of 
Paraguaçu  Paulista;  and  (iii)  pay  an  administrative  penalty  in  the  amount  of  R$116,900  for 
environmental damage.  The decision also imposes a daily penalty if the Company fails to comply 
with numbers (i) and (ii) above.  The Company has appealed this decision and such decision will 
not be effective until a final ruling is issued on this appeal. The Company has assessed the risk of 
loss in this case as possible.   

A  civil  public  action  was  brought  against  the  Company  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 that the Company collects, 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  allegedly  caused  by  the  installation  and  operation  of  the 
Cantareira  water  distribution  system.    The  Company  presented  its  defense  in  January  2004, 
alleging that the plaintiff has no standing to bring this action and that some of the requests are 
inconsistent  and/or  impossible.    The  Company  has  explained  that  the  water  collection  limit  was 
duly authorized by law and by the competent governmental agency, and that the plaintiff did not 
prove or  specify  the  damages.    The  injunction  was  not  granted,  and this  action  is  now  awaiting 
judgment on the first instance. 

On  February  25,  2003,  a  request  for  a  preliminary  injunction  was  filed  against  the  Company, 
restricting it from disposing of sewage without due treatment in the municipality of Lutécia.  The 
injunction  also  determined  that  payments  for  water  and  sewage  services  by  users  be  deposited 
with  the  court  until  the  Company  has  made  the  necessary  investment  in  the  water  and  sewage 
system  of  the  municipality,  in  addition  to  paying  a  daily  fine  in  the  amount  of  R$300,000  (one 
thousand minimum salaries) in the event the case is decided against it.  After submission of an 
expert  report,  the  Public  Prosecutor  Office  requested that the Company  be  sentenced to pay  an 
amount  of  R$82,800.  In  anticipation  of  a  settlement  with  the  Public  Prosecutor  Office,  the 
Company condemned the area and requested the respective environmental licenses for it. 

The Company is also party to a number of other civil public actions brought by municipalities that 
seek  cessation  of  the  collection  of  fees  relating  to  sewage  services,  alleging  that  the  Company 
does  not  treat  the  sewage  in  such  municipalities  and  that  it  has  failed  to  make  certain 
investments in sewage treatment systems as provided in the relevant concession agreements.   

The  Company  is  also  party  to  several  administrative  proceedings  with  CETESB  –  Companhia  de 
Tecnologia  de  Saneamento  Ambiental  (Environmental  Sanitation  Technology  Company)  seeking 
the  imposition  of  penalties  for  environmental  damages  allegedly  caused  by  the  Company  and 
other regulatory matters.  However, the Company does not believe that the final determination in 
these  proceedings  will,  individually  or  in  the  aggregate,  have  a  material  adverse  effect  on  its 
business, results of operations, financial condition or prospects. 

At December 31, 2005, the Company had provisioned R$24,198 for environmental claims. 

(vi) Other proceedings relating to concessions 

The Company is also party to a number of proceedings related to its concessions.

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

In December 1997, the municipality of Santos enacted a law expropriating the Company’s water 
and sewage systems in Santos.  In response, the Company 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 Appeals  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 the Company’s favor by 
a  lower  court,  but  that  decision  remains  subject  to  appeal.  Despite  the  pending  lawsuit,  the 
Company continues to provide water and sewage services to Santos. 

In  connection  with  discussions  held  with  the  municipality  of  Presidente  Prudente,  the  Company 
filed a suit against the municipality seeking a court decision determining the continuation of the 
concession  agreement  with  that  municipality  until  the  indemnification  payment  owed  to  the 
Company  in  connection  with  the  return  of  water  and  sewage  system  of    Presidente  Prudente  is 
made.  The lower court issued a decision in the Company’s favor to the effect that it still continue 
to  provide  services  in  the  municipality  until  the  indemnification  provided  for  in  the  concession 
agreement is paid. 

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  the  Company,  claiming  that 
Municipal  Law  No.  3,593/04  is  unconstitutional  and  seeking  termination  of  the  Company’s 
concession agreement with the municipality.  Although an injunction was granted, the São Paulo 
State  Court  of  Appeals  has  stayed  the  injunction.    On  March  23,  2005,  the  House  of 
Representatives  of  Itapira  approved  a  decree  revoking  the  concession  agreement.    In  addition, 
Municipal  Law  No.  3,730/05  was  enacted  revoking  an  earlier  law  which  authorized  the 
municipality to enter into the concession agreement. The Municipality of Itapira has further filed 
an action against the Company 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.  The 
Company  has  appealed  this  ruling  but  has  not  been  able  to  suspend  the  effects  of  the  decision 
until  final  judgment.  Accordingly,  the  Company  is  currently  not  rendering  water  and  sewage 
services at Itapira. A trial decision on this litigation is still pending. 

The  Municipality  of  Sandovalina  has  brought  a  legal  action  against  the  Company  seeking  to  (i) 
obtain  the  termination  of  the  Company’s  concession  and  (ii)  obtain  remedies  for  environmental 
damage  and  alleged  losses  caused  to  the  municipality  due  to  its  failure  to  provide  sewage 
treatment,  as  well  as  other  damage  caused  to  public  property.  The  Company  responded  with  a 
counterclaim against the municipality for payment of R$ 115 related to the supply of water from 
December  1999  to  August  2003.  The  Company  is  also  seeking  the  payment  of  a  contractual 
indemnification based on the early termination of the contract.  The Company currently continues 
to  operate  the  water  and  sewage  systems  of  Sandovalina,  and  the  lawsuit  is  still  in  the  fact-
finding phase. 

The  Municipality  of  Salto  de  Pirapora  has  obtained  an  injunction  to  regain  control  of  the  basic 
sanitation.  The  Company  has  filed  a  lawsuit,  aiming  at  suspending  the  effects  of  the  injunction 
granted, which has been accepted. 

In addition, the Company is party to a number of proceedings with the Public Prosecution Office 
and  several  municipalities  which  have  contested  its  right  to  charge  a  tariff  for  sewage  services 
provided as opposed to charging a fixed fee for these services.  In most of these proceedings, the 
Company has received decisions in its favor.  In addition, the Supreme Court has confirmed the 
understanding  that  the  Company  has  the  right  to  charge  a  tariff  for  the  sewage  services  it 
provides.  The Company does not believe that the final outcome of these proceedings will have a 
material adverse effect on its business, results of operations, financial condition or prospects.

The  Company  is  authorized  to  increase  its  capital  up  to  a  maximum  of  R$ 4,100,000  registered 
common shares without par value, upon resolution of the board of directors. 

The Company has from time to time issued shares to purchase assets from third parties, usually

In October 2004, the State of São Paulo Government sold 5.27 billion of its common shares, of 
which  1.43  billion  were  sold  in  Brazil  and  3.84  billion  were  sold  as  15.36  million  American 
Depositary Shares (“ADSs”) on the New York Stock Exchange - NYSE. 

(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, 2005, 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 2005 is as follows:

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$ 
324,461,  net  of  withheld  income  tax  in  the  amount  of  R$  23,755,  in  2005.  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,  has 
been reflected directly in “Shareholders’ equity” in conformity with CVM Deliberation No. 207/96. 

(d) 

Capital reserve 

Capital reserve comprises of tax incentives and donations from government agencies and private 
entities. 

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.

Management  will  propose  to  transfer  the  balance  of  retained  earnings  in  the  amount  of 
R$ 563,598 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 

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, 2005 and 2004 are as follows:

The  market  values  determined  by  the  Company  were  based  on  available  information  and 
appropriate  valuation  methodologies,  both  of  which  require  considerable  judgment  and 
estimates.    Consequently,  the  estimates  of  fair  values  presented  above  do  not  necessarily 
indicate the amounts that might be realized or settled in a current market transaction. The use of 
different  market  approaches  and/or  methodologies  could  have  a  significant  effect  on  the 
estimated market values. 

(a)    Exchange rate risk 

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.  The  Company  does  not  enter  into  hedge  or 
swap  transactions  to  mitigate  foreign  currency  risk,  given  the  amounts  and  related  costs 
involved.  However,  at  times,  it  may  enter  into  forward  exchange  transactions  and  financial 
funding transactions in Brazilian reais to mitigate foreign currency exposure. 

A significant portion of the Company’s debt is denominated in foreign currency, primarily the US 
dollar  and  the  Euro,  totaling  R$  1,575,948  (see  Note  9).  The  Company’s  net  exposure  to  the 
exchange rate risk at December 31, 2005 and 2004 is summarized as follows:

€

December 31, 2004

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,  2005  and  2004,  the  Company  had  loans  and 
financing in the amount of R$ 1,327,694 and R$ 981,928, respectively, at variable interest rates

(primarily indexed to CDI and TJLP). 

Another  risk  faced  by  the  Company  is  that  adjustments  to  the  Company’s  related  water  and 
sewage  tariff  rates  are  not  necessarily  correlated  with  the  increases  in  the  interest  rates  and 
price-level restatement indices associated with the Company’s debt.  

(c)    Credit risk  

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, 2005, 2004, and 2003. 

(d)     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.  

(e)     Valuation of financial instruments 

The  Company’s  main  financial  instruments  of  the  Company  as  of  December  31,  2005  and  the 
criteria adopted for their valuation are as follows: 

(i)  Cash  and  cash  equivalents  –  These  comprise  cash  on  hand,  bank  accounts,  short-term 
investments and forward exchange transactions. The market value of these assets is not different 
from the amounts stated in the Company’s balance sheet. 

(ii)  Loans  and  financing  and  debentures  had  their  market  value  determined  based  on  the 
discounted cash flow, using the interest rate projections available.

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

22.  

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$ 1,247,117 and 
R$ 1,309,072  at  December  31,  2005  and  2004,  respectively,    due  to  the  additional 
inflation restatement adjustments. 

(ii)  Supplementary inflation restatement replaces revaluation of property, plant and equipment 

for US GAAP 

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  (loss)  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$ 2,924,881 and R$ 3,028,301 at 
December  31,  2005  and  2004,  respectively,  due  to  the  supplementary  inflation 
restatement  adjustments  and  reduced  by  R$  2,529,771  and  R$  2,619,220  at  December 
31,  2005  and  2004,  respectively,  due  to  the  reversal  of  the  revaluations,  before  tax 
effects. 

(iii)  Inflation indices 

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 (see above).

(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  monetary 
variation 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$  1,304,723  and  R$  1,325,935  at 
December  31,  2005  and  2004,  respectively,  due  to  deferred  tax  adjustments  on  US  GAAP 
differences,  excluding 
to  monetary 
revaluations  and  permanent  differences 
readjustment on land of approximately R$ 150,0 million. 

related 

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.  No  adjustments  have  been  included  in  the  reconciliation 
from  BR  CL  to  US  GAAP,  as  the  reported  amounts  of  cash  and  cash  equivalents  under  BR  CL 
qualify under US GAAP. 

(e)  Investments in debt and equity securities 

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$ 30  andR$ 92  at  December  31,  2005

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

and 2004, 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 

For US GAAP reconciliation  purposes, net revaluation of property, plant and equipment in 
the  amounts  of  R$  2,529,771  and  R$  2,619,220  at  December  31,  2005  and  2004, 
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$ 89,449, R$ 104,500 and R$ 134,245 for the years ended December 31, 2005, 
2004  and  2003,  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 related 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  interest,  including  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  real-denominated 
borrowings  and  the  foreign  exchange  gains  and  losses  on  foreign  currency  denominated 
borrowings.

(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.

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

(g)  Deferred charges 

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 under BR CL was R$ 20,531 and R$ 39,097 at 
December  31,  2005  and  2004,  respectively,  and  was  written-off  for  US  GAAP  purposes.    The 
net  effects  from  amortization  and  deferrals  in  the  statement  of  operations  at  December  31, 
2005  and  2004  were  an  increase  of  R$ 18,566  and  R$ 9,854  respectively,  at  December  31, 
2003 was reduction of R$ 3,894. 

(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.

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

Although  the  recently  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.  

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. 

(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 
Government for pensions paid was charged to income, as this amount related 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) is 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

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,  2005,  2004  and  2003,  total 
amounts  not  accrued  were  R$  (968),  R$  (14,743)  and  R$  140,  respectively.  Such 
amounts, consistent with the US GAAP difference mentioned above, were ‘pushed down’ as 
expenses in the reconciliation to US GAAP.  

(iv) Summary of pension benefits adjustments 

The  effects  included  in  the  shareholders'  equity  reconciliation  arising  from  these  different 
criteria for pension and benefit accounting are presented below:

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

(j)  Costs associated with issuance of debentures 

Under  BR  CL  the  costs  associated  with  issuance  of  debenture  are  recognized  as  a  operational 
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,  2005,    the  balance  of  deferred  debt  issue  costs 
included as an adjustment to shareholders’ equity, primarily related to debt issue costs incurred 
in 2005 was R$ 13,976, net of accumulated  amortization. 

(k)  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. 

(l)  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. 

(m) Provision for dividends and interest on shareholders' equity 

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

(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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, 2005, 2004 and 2003 were as follows:

No other dividend distributions, other than interest on shareholders’ equity was declared by the 
Company for the years ended December 31, 2005, 2004 and 2003. 

(n)  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. 

(o)  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. 

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. 

(p)  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.

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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, 2005 and 2004.. 

(q)  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. 

(r)  Earnings per share 

Under BR CL, net income (loss) 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.  

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. 

The  weighted-average  number  of  shares  used  in  computing  basic  earnings  per  share  for 
December  31,  2005,  2004  and  2003  was  28,479,577,827.  The  Company  had  no  potentially 
dilutive shares outstanding during 2005, 2004 or 2003.

NOTES TO THE FINANCIAL STATEMENTS 

AS OF AND FOR THE YEARS ENDED DECEMBER 31, 2005, 2004 AND 2003 
(Amounts in thousands of Brazilian reais-R$, unless otherwise stated) 

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 22, 23 and 24. 

(t)  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).

(t)  New and recently issued US GAAP accounting pronouncements 

In  June  2005,  the  FASB  issued  SFAS  No.  154,  “Accounting  Changes  and  Error  Corrections,  a 
replacement  of  APB  Opinion  No.  20  and  FASB  Statement  No.  3”.  SFAS  154  requires 
retrospective  application  to  financial  statements  of  prior  periods  for  changes  in  accounting 
principles  as  if  such  principles  had  always  been  used.  The  cumulative  effect  of  the  change  is 
reflected  in  the  carrying  value  of  assets  and  liabilities  as  of  the  first  period  presented  and  the 
offsetting  adjustments  are  recorded  to  opening  retained  earnings.  This  statement  is  effective 
January 1, 2006. The Company will apply this statement as of January 1, 2006 as such changes 
in accounting principles occur.  

In March 2005, the FASB issued FASB Interpretation No. 47, “Accounting for Conditional Asset 
Retirement  Obligations”.  This  statement  requires companies  to  recognize  a  liability  for  the  fair 
value  of  a  legal  obligation  to  perform  asset  retirement  obligations  that  are  conditional  on  a 
future  event  if  the  amount  can  be  reasonably  estimated.  This  statement  becomes  effective  on 
December 31, 2005. Management has previously evaluated the application of FASB Statement 
No. 143 to its operations and concluded that no material effects would be expected.

The date used to determine pension benefits was  December 31, 2005. 

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 
liabilities,  types  and  availability  of  financial  instruments  in  the  local  market,  general 
economic  conditions  and  forecasts  as  well  as  requirements  under  local  pension  plan  law. 
The plan’s asset allocation and external asset management strategies are determined with 
the  support  of  reports  and  analyses  prepared  by  “SABESPREV”  and  independent  financial 
consultants.  Under  its  current  investment  strategy,  pension  assets  of  the  Company  are 
allocated with a goal to achieve the following distribution:

(b)  Other information 

(i)   Concentration of labor in unions –  

Approximately  70%  of  all  the  Company’s  employees  are  members  of  unions.    The  four 
main unions that represent the Company’s 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,  Baixada  Santista,  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.    Every  year  the  Company  negotiates  collective 
bargaining agreements, which establish the level of compensation and other benefits of the 
employees. 

(ii)  Proposed regulations/pending legislation for the basic sanitation sector  

There  is  not,  at  the  present  time,  any  specific  regulation  in  connection  with  sanitation 
services  in  Brazil.  Accordingly,  the  Brazilian  Federal  Congress  has,  from  time  to  time, 
discussed  proposals  for  regulation,  which  would  establish  directives  for  basic  sanitation 
services. 

Currently,  several  bills  are  under  debate  at  the  Brazilian  Federal  Congress  and  at  the 
Brazilian Senate.  Both Houses of Representatives have agreed upon the creation of a joint 
committee (comissão mista) that will be responsible for the organization and systemization 
of  the  proposed  regulation  for  water  and  sewage  services  in  Brazil.    Any  proposed 
regulation, when and if approved, could establish a new municipal regulatory authority for 
the sanitation industry that may, in part, preempt the existing State regulatory authorities 
under which we operate in the Metropolitan Region. 

(iii)  State elections in 2006  

Many of the Company’s transactions with the State reflect policies of the State that depend 
on  decisions  of  elected  officials  or  public  servants  and  are  accordingly  subject  to  change.  
They may be particularly open to reconsideration following State elections, which are next 
scheduled  to  be  held  in  October  2006.    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  the  Company  uses 
state-owned reservoir facilities.

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.
