PRESENTATION OF FINANCIAL AND OTHER INFORMATION 

General 

We maintain our books and records in reais.  We prepared our consolidated financial statements as of 
and for the years ended December 31, 2009, 2010 and 2011 included in this annual report in compliance 
with  International  Financial  Reporting  Standards,  or  IFRS,  as  issued  by  the  International  Accounting 
Standards Board, or IASB. 

Convenience Translations 

We have translated some of the real amounts contained in this annual report into U.S. dollars.  The 
rate  used  to  translate  such  amounts  in  respect  of  the  year  ended  December 31,  2011  was  R$1.876  to 
US$1.00, which was the commercial rate for the purchase of U.S. dollars in effect on December 31, 2011, 
as reported by the Central Bank.  The U.S. dollar equivalent information presented in this annual report is 
provided  solely  for  the  convenience  of  reader  and  should  not  be  construed  as  implying  that  the  real   
amounts  represent,  or  could  have  been  or  could  be  converted  into,  U.S.  dollars  at  the  above  rate.   See 
“Item 3.A.   Selected  Financial  Data—Exchange  Rates”  for  more  detailed  information  regarding  the 
Brazilian foreign exchange system and historical data on the exchange rate of the real   against the U.S. 
dollar. 

Rounding 

Some  percentages  and  numbers  included  in  this  annual  report  have  been  subject  to  rounding 
adjustments.  Accordingly, figures shown as totals in certain tables may not be an arithmetic aggregation 
of the figures that precede them.

We make statements in this annual report about our market share and other information relating to

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

(2)    Measured  in  liters/connection  per  day,  according  to  the  method  of  measuring  our  water  losses,  based  on  worldwide  market 
practice  for  the  sector.   See  “Item 4.B.  Business  Overview—Description  of  Our  Activities—Water  Operations—Water 
Losses.” 

Exchange Rates 

In the past, the Brazilian National Monetary Council (Conselho Monetário Nacional), or the CMN, 
has introduced changes to the Brazilian foreign exchange regime, such as unifying the Commercial and 
Floating Markets and easing the rules governing Brazilian residents’ ability to acquire foreign currency, 
among others.  On March 24, 2010, the CMN and the Central Bank approved Resolution No. 3,844, under 
which a series of measures were adopted to consolidate and simplify acts and proceedings applicable to 
foreign exchange market regulations in Brazil. 

The Brazilian foreign exchange system allows for the purchase and sale of foreign currency and the 
international transfer of reais by any person or legal entity, regardless of the amount, subject to certain 
regulatory procedures. 

The  Brazilian  currency  has,  during  the  last  few  decades,  experienced  frequent  and  substantial 
variations  in  relation  to  the  U.S.  dollar  and  other  foreign  currencies.  Between  2003  and  mid-2008,  the 
real appreciated significantly against the U.S. dollar with the exchange rate reaching R$1.634 in August 
2008.   Primarily,  as  a  result  of  the  global  financial  crisis,  the  real  depreciated  32.0%  against  the  U.S. 
dollar  during  2008  and  closed  the  year  at  R$2.337  per  US$1.00,  but  strengthened  during  2009  and 
2010. In 2011, the real suffered a deprecitation of 12.6% against the U.S. dollar.  On December 31, 2009, 
2010  and  2011,  the  real/U.S. dollar  exchange  rate  was  R$1.741,  R$1.666  and  R$1.876  per  US$1.00, 
respectively.     

The  Central  Bank has  intervened occasionally  to  combat  instability  in  foreign  exchange  rates.  We 
cannot predict  whether  the Central  Bank or  the  Brazilian government  will  continue  to  let  the  real  float 
freely or will intervene in the exchange rate through a currency band system or otherwise.  The real may 
fluctuate  against  the  U.S. dollar  substantially  in  the  future.   For  further  information  on  these  risks,  see 
“Item 3.D. Risk Factors—Risks Relating to Brazil—Exchange rate instability may adversely affect us and 
the market price of our common shares or ADSs.” 

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

Risks Relating to Brazil 

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

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

(cid:131)       the regulatory environment related to our business operations and concession agreements; 

(cid:131)       interest rates;   

(cid:131)       exchange rates and exchange controls and restrictions on remittances abroad;   

(cid:131)       currency fluctuations;   

(cid:131)       inflation;    

(cid:131)       liquidity of the Brazilian capital and lending markets;   

(cid:131)       tax and regulatory policies and laws;   

(cid:131)       economic and social instability; and   

(cid:131)       other political, diplomatic, social and economic developments in or affecting Brazil.

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

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

Brazil  has,  in  the  past,  experienced  extremely  high  rates  of  inflation.   Inflation  and  the  Brazilian 
government’s  measures  to  combat  inflation  have  had  significant  negative  effects  on  the  Brazilian 
economy,  contributing  to  economic  uncertainty  and  heightened  volatility  in  the  Brazilian  securities 
markets.   The  Brazilian  government’s  measures  to  control  inflation  have  often  included  maintaining  a 
tight  monetary  policy  with high  interest  rates,  thereby  restricting  the  availability  of  credit  and  reducing 
economic  growth.   The  Special  Clearing  and  Settlement  System  (Sistema  Especial  de  Liquidação  e 
Custódia), or SELIC, the official overnight interest rate in Brazil, at the end of 2009, 2010 and 2011 was 
8.65%, 10.66% and 10.91% respectively, in line with the target rate set by the Brazilian Committee on 
Monetary Policy (Comitê de Política Monetária), or COPOM.   

The  annual  rate  of  inflation,  as  measured  by  the  General  Market  Price  Index  (Índice  Geral  de 
Preços—Mercado), or IGP-M index, fell from 9.95% in 2000 to 3.83% in 2006, increased to 7.75% in 
2007  and  further  increased  to  9.81%  in  2008.   According  to  the  IGP-M  index,  in  2009,  there  was  a 
deflation  of  1.71%  and  the  rate  of  inflation  for  2010  and  2011  were  11.32%  and  5.1%  respectively.  
Brazilian  governmental  actions,  including  interest  rate  decreases,  intervention  in  the  foreign  exchange 
market and actions to adjust or fix the value of the real, may trigger increases in inflation.  If Brazil again 
experiences high inflation, our costs and expenses may rise, we may be unable to increase our tariffs to 
counter  the  effects  of  inflation,  and  our  overall  financial  performance  may  be  adversely  affected.   In 
addition, a substantial increase in inflation may weaken investors’ confidence in Brazil, causing a decline 
in the market price of our common shares or ADSs. 

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

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

The  Brazilian  currency  experienced  frequent  and  substantial  devaluations  in  relation  to  the  U.S. 
dollar  and  other  foreign  currencies  during  the  last  decades.   Throughout  this  period,  the  Brazilian 
government  has  implemented  various  economic  plans  and  utilized  a  number  of  exchange  rate  policies, 
including  sudden  devaluations,  periodic  mini-devaluations  during  which  the  frequency  of  adjustments 
ranged from daily to monthly, floating exchange rate systems, exchange controls and dual exchange rate 
markets.   From  time  to  time,  there  have  been  significant  fluctuations  in  the  exchange  rate  between  the 
Brazilian real  and the U.S. dollar and other currencies.  For example, the real appreciated 13.8%, 9.5% 
and  20.7%  against  the  U.S.  dollar  in  2005,  2006  and  2007,  respectively.  In  2008,  as  a  result  of  the 
worsening of the international economic crisis, the real depreciated by 32.0% against the U.S. dollar.  In 
2009  and  2010,  the  real  appreciated  25.5%  and  4.3%  against  the  U.S.  dollar,  closing  at  R$1.741  and 
R$1.666 per US$1.00, respectively.  In 2011, the real suffered a depreciation of 12.6% against the U.S. 
dollar, closing at R$1.876 per US$1.00. There can be no assurance that the real will not further depreciate 
against the U.S. dollar.  As of April 23, 2012, the commercial selling rate as reported by the Central Bank 
was R$ 1.886 per US$1.00. 

Depreciation of the real against the U.S. dollar could create inflationary pressures in Brazil and cause 
increases in interest rates, which could negatively affect the growth of the Brazilian economy as a whole 
and harm our financial condition and results of operations, curtail access to financial markets and prompt 
government intervention, including recessionary governmental policies.  Depreciation of the real against 
the  U.S.  dollar  can  also,  as  in  the  context  of  the  current  global  economic  recovery,  lead  to  decreased 
consumer spending, deflationary pressures and reduced growth of the economy as whole. 

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 

10 

 
because  our  tariff  revenue  and  other  sources  of  income  are  denominated  solely  in  reais.   In  addition, 
because we have foreign currency denominated indebtedness, any significant devaluation of the real   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$3,053.4  million  as  of  December 31,  2011,  and  we 
anticipate  that  we  may  incur  substantial  amounts  of  foreign  currency  denominated  indebtedness  in  the 
future.  In 2011, our results of operations were negatively affected by the 12.6% depreciation  of the real   
against  the  U.S.  dollar,  which  amounted  to  R$382.3  million.   We  do  not  currently  have  any  hedging 
instruments in place to protect us against a devaluation of the real in relation to any foreign currency.  A 
devaluation of the real   may adversely affect us and the market price of our common shares or ADSs.  

Developments and the perception of risk in other countries, especially in the United States and in 
emerging market countries, may adversely affect the market price of Brazilian securities, including our 
common shares and ADSs. 

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

The global financial crisis has had significant consequences, including in Brazil, such as stock and 
credit  market  volatility,  unavailability  of  credit,  higher  interest  rates,  a  general  slowdown  of  the  world 
economy, volatile exchange rates, and inflationary pressure, among others, which have and may continue 
to, directly or indirectly, materially and adversely affect us and the price of securities issued by Brazilian 
companies, including our common shares and ADSs.    

Risks Relating to Our Control by the State of São Paulo  

We are controlled by the State of São Paulo, whose interests may differ from our or from minority 

shareholders’ interests, which could have a material adverse effect on us. 

The State of São Paulo, through its ownership of our common shares, has the ability to determine our 
operating  policies  and  strategy,  to  control  the  election  of  a  majority  of  the  members  of  our  board  of 
directors  and  to  appoint  our  senior  management.  As  of  April  23,  2012,  the  State  owned  50.3%  of  our 
outstanding common shares. 

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

Following the 2010 elections for State governor, in 2011 the new governor elected Ms. Dilma Seli 
Pena  as  our  chief  executive  officer  and  Mr.  Edson  de  Oliveira  Giriboni,  the  Secretary  of  State  for  the 
State Secretariat for Sanitation and Water Resources (Secretaria de Saneamento e Recursos Hídricos do 
Estado de São Paulo), was elected as chairman of our board of directors.  

We  have  a  substantial  amount  of  accounts  receivable  owed  to  us  by  the  State  and  some  State 

entities, and we cannot assure you as to when or whether the State will pay us.  

Historically,  the  State  and  some State  entities  have had  substantial  overdue  accounts payable  to  us 
relating to (i) the provision of water and sewage services and (ii) 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, 2011, the amounts owed to us by the State for the provision of water 
and sewage services totaled R$145.4 million.  With respect to payment of pensions on behalf of the State, 
as  of  December  31,  2011,  we  believe  that  the  State  owed  to  us  R$1,290.7  million,  but  due  to  the 
uncertainty  regarding  the  recovery  of  the  amount  our  management  decided  not  to  record  the 

11 

 
reimbursements that we believe are due to us.  In addition, as of December 31, 2011, we had recorded a 
provision  for  actuarial  liability  in  the  amount  of  R$1,512.1  million  in  respect  of  future  supplemental 
pension  payments  the  State  does  not  believe  it  is  responsible  for  paying.   Amounts  owed  to  us  by  the 
State for water and sewage services and reimbursements for pensions paid may increase in the future.  

We have entered into agreements with the State to settle these overdue amounts payable to us.  For a 
detailed  discussion  of  these  agreements,  see  “Item 7.B.  Related  Party  Transactions,”  and  Note  8  to  our 
consolidated financial statements.  Pursuant to these agreements, the amounts due with respect to water 
and  sewage  services  through  December 2007  could  be  settled  through  the  application  of  dividends 
payable by us to the State.  In December 2007, the State agreed to pay us the outstanding balance in the 
amount  of  R$133.7 million  (as  of  November 30,  2007),  in  60  consecutive  monthly  installments, 
beginning on January 2, 2008, and an amount of R$236.1 million relating to part of the accounts overdue 
and unpaid from March 2004 through October 2007 regarding the provision of water supply and sewage 
collection  services.   We  agreed  to  pay  the  State  the  outstanding  balance  of  dividends,  in  the  form  of 
interest  on  shareholders’  equity,  due  from  March 2004  through  December 2006,  in  the  amount  of 
R$400.8 million, in the period from January through March 2008.   

In  March 2008,  we  entered  into  a  commitment  agreement  with  the  State  for  the  settlement  of 
outstanding  debts  related  to  the  reimbursement  of  pension  benefits.   Pursuant  to  the  commitment 
agreement,  the  amounts  due  to  us  with  respect  to  payments  of  pensions  on  behalf  of  the  State  may  be 
partially settled through the transfer to us of certain reservoirs in the Alto Tietê System that we use and 
are  owned  by  the  State.   In  November 2008,  we  entered  into  an  agreement  with  the  State  relating  to 
payments  of  pension  benefits  made  by  us  on  its  behalf.   The  State  acknowledged  that  it  owed  us  the 
outstanding  balance  of  R$915.3  million  as  of  September 30,  2008  relating  to  payments  of  pension 
benefits made by us on its behalf.  We provisionally accepted the reservoirs in the Alto Tietê System as 
partial payment (R$696.3 million) subject to the transfer of the property rights of these reservoirs to us.  
In  November 2008,  the  State  began  paying  the  remaining  balance  in  the  amount  of  R$219.0 million  in 
114 successive monthly installments.  We are unable to predict whether and when these reservoirs will be 
transferred to us because the Public Prosecution Office of the State of São Paulo (Ministério Público do 
Estado  de  São  Paulo)  filed  a  civil  public  action  alleging  that  a  transfer  to  us  of  ownership  of  the  Alto 
Tietê  System  reservoirs  is  illegal.   The  Company  and  the  São  Paulo  State  Government  are  working 
together  to obtain  legislative authorization  to  transfer  the reservoirs  to us, overcoming  the uncertainties 
arising  from  the  public  lawsuit  challenging  the  absence  of  a  specific  legislative  authorization  for  the 
transfer of the property of the reservoirs. 

See “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—
Legal  Proceedings—Other  Legal  Proceedings.”   In  addition  to  the  R$915.3  million  that  the  State 
acknowledges  it  owes  us  pursuant  to  the  November 2008  agreement,  we  are  negotiating  with  the  State 
further amounts that the State does not recognize it owes us.  While we continue to negotiate directly with 
the State, we are not able to assure you that we will be successful in these negotiations.  Accordingly, as 
of December 31, 2011, we have not recorded R$1,290.7 million related to reimbursements that we believe 
are due to us for pension benefits paid on behalf of the State, but we have recorded R$1,512.1 million in 
pension obligations.   

We cannot assure you when or if the State will pay the total overdue amounts owed to us.  Due to the 
State’s history of not making timely payments to us in respect of services and of not reimbursing us in a 
timely manner for the payments of pensions on behalf of the State, we cannot assure you that the amount 
of accounts receivable owed to us by the State and some State entities will not significantly increase in 
the future. 

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

In connection with the provision of water services, we use the Billings and Guarapiranga reservoirs 
which are owned by a State-controlled company, the Water and Energy Metropolitan Company (Empresa 
Metropolitana de Águas e Energia S.A.), or the EMAE.  We are entitled to use these reservoirs based on a 
grant issued by the State Department of Water and Energy (Departamento de Águas e Energia Elétrica 
do Estado de São Paulo), or DAEE.  The State, through its control of our board of directors, could require 
us to acquire the Billings and Guarapiranga reservoirs.  As a result of these acquisitions, our cash position 
and  overall  financial  condition  could  be  adversely  affected.   In  addition,  since  we  are  not  currently 

12 

 
charged for the use of these reservoirs, we are uncertain as to whether we will continue to be able to use 
the reservoirs without paying charges, or what the likely fee scale would be, if imposed.  We may also be 
required to pay additional maintenance and operational costs for our use of the Billings and Guarapiranga 
reservoirs.   If  we  were  required  to  pay  substantial  charges  to  the  owner  or  additional  maintenance  or 
operational costs for our use of these reservoirs, we could be materially and adversely affected.   

Risks Relating to Our Business 

We  cannot  anticipate  the  effects  that  further  developments  of  the  Basic  Sanitation  Law  and  its 

interpretation will have on the basic sanitation industry in Brazil and on us. 

Law No. 11,445, or the Basic Sanitation Law, was enacted on January 5, 2007.  While it has been in 
effect for more than five years, it is still in its early stages of implementation in Brazil, and we continue to 
be unable to anticipate all of the effects that it might have on our operations and business.  There are still 
several  uncertainties  related  to  the  interpretation  of  the  Basic  Sanitation  Law.   On  June 21,  2010,  the 
federal government enacted Federal Decree No. 7,217 regulating the Basic Sanitation Law.  Among other 
things, Law No. 11,445 and Federal Decree No. 7,217 provided that (i) public hearings regarding the bid 
announcements and technical and economic viability studies are requirements for the validity of public-
public  partnership  contracts  (program  contracts) ;  (ii)  the  rights  and  obligations,  including  penalties,  of 
customers and service providers shall be ruled by the owner of the public service, not by the regulatory 
agency; (iii) financial feasibility may be demonstrated by means of the requirement for new investments, 
other  than  the  proceeds  arising  from  the  rendering  of  services;  and  (iv)  when  a  service  is  divided  and 
rendered  by  different  service  providers,  the  services  will  be  considered  as  interdependent  and  will  be 
subject  to  an  agreement  that  will  regulate  the  activities  of  the  different  services  providers.   We  cannot 
currently anticipate all the effects that the law and the decree will have on our business and operations, if 
any.  

Pursuant  to  the  Basic  Sanitation  Law,  tariff  regulation  is  to  be  performed  by  an  independent 
regulatory  entity.   To  exercise  this  assignment,  the  State  of  São  Paulo  created  the  São  Paulo  State 
Sanitation and Energy Regulatory Agency, or the ARSESP. The ARSESP is the State agency responsible 
for  regulating  the  basic  sanitation  industry,  including  tariff  regulation  in  certain  municipalities.   The 
ARSESP acts as tariff regulator both in municipalities where the State provides basic sanitation services 
(municipalities  in  metropolitan  areas),  and  in  those  municipalities  that  have  delegated  their  regulatory 
powers to the State through cooperation agreements.  The ARSESP presently regulates our tariff structure 
and  adjustments  pursuant  to  the  same  tariff  structure  and  adjustment  formula  that  we  otherwise  apply.  
Pursuant  to  a  cooperation  agreement  among  the  State  and  some  municipalities,  the  ARSESP  also 
regulates our tariffs in municipalities that have selected the ARSESP to regulate our tariffs. 

Since  2008,  the  ARSESP  has  been  developing  new  concepts  in  the  tariff  structure  and  adjustment 
formula.  In July 30, 2010, the ARSESP published Resolution No. 156 establishing the methodology and 
general  criteria  for  the  definition  of  our  regulatory  asset  base,  in  order  to  move  forward  with  the  tariff 
review process and to define the initial parameters of the auditing process that the ARSESP will have to 
conduct  pursuant  to  the  terms  of  the  Basic  Sanitation  Law.   Throughout  2011  and  2012,  the  ARSESP 
commenced public consultations regarding the methodology for tariff revisions. The ARSESP estimates 
that  a  final  public  hearing  at  which  our  preliminary  average  tariff,  efficiency  gains  factor  and  tariff 
structure will be subjected to public scrutiny will be scheduled by November 2012. However, although 
the ARSESP has indicated that it will implement the new tariff methodology in 2012, we cannot assure 
you  when  the  new  rules  will  be  enacted,  and  the  aforementioned  schedule  may  suffer  alterations  or  be 
subject to delays. We cannot anticipate the additional changes that the ARSESP will implement on our 
tariff structure and adjustment formula or the effects that these changes will have on us.  If the changes 
are unfavorable to us, they could materially and adversely affect us.  

Furthermore,  since  Law  No.  11,445  permits  municipalities  to  create  their  own  regulatory  agencies 
rather  than  being  subjected  to  overview  by  the  ARSESP,  a  number  of  municipalities  created  their  own 
regulatory  agencies.  The  municipality  of  Lins,  which  had  decided  in  2007  to  create  its  own  regulatory 
authority, revised this decision in 2010 and transferred the regulation of the water activities performed in 
Lins, including the setting of tariffs to the ARSESP. Lins has retained, however, the power to ultimately 
approve the tariff set by the ARSESP.  The municipalities in which the hydrographic basins of the rivers 
Piracicaba, Capivari and Jundiaí are located have created a consortium for regulation and supervision of 
our  activities  in  that  area.  As  this  regulatory  entity  has  recently  been  created, we  cannot  predict  how  it 

13 

 
may  implement  regulation  changes  that  may  affect  our  activities.  If  other  municipalities  create  new 
agencies or retain regulatory powers, we will be subject to their regulation, supervision and limitations to 
our  services.  We  cannot  foresee  any  changes  that  any  such  new  agency  may  implement  regarding  our 
business, and if the changes are unfavorable, they could materially and adversely affect us. 

Pursuant  to  the  Basic  Sanitation  Law,  the ARSESP has enacted,  in  2009,  certain rules  establishing 
(i) the general conditions for the services we render, (ii) the communication process for any failure in our 
services; (iii) penalties for deficiencies in the provision of basic sanitation services; and (iv) procedures 
for  confidential  treatment  of  our  clients’  private  information.   We  are  currently  evaluating  the 
enforceability and legality of some of these rules.  Implementation of these rules started during 2011 and 
is  expected  to  continue  for  the  next  few  years.   The  implementation  of  these  rules  will  impact  our 
commercial and operations processes and may adversely affect us as described below and in other ways 
we cannot currently predict. 

In  particular,  regarding  changes  to  the  general  conditions  for  our  services,  in  2011  the  ARSESP 
altered  the  standard  contract  that  we  are  required  to  use  in  our  relationships  with  retail  costumers.  The 
ARSESP changed the rule regarding the collection of water and sewage tariff, requiring that collection be 
directed to the consumer of our services, rather than to the owner of the served property, as used to be the 
case.  We  estimate  that  this  change  will  affect  ongoing  legal  disputes,  particularly  those  regarding 
collection procedures, as well as business discussions in general. However, we are not currently able to 
predict the impact of this change on our business, as the change is still being implemented.

information,  see  “Information  on 

the  Company—Business  Overview—Tariffs,” 
“Information on the Company—Business Overview—Government Regulation—Tariff Regulation in the 
State of São Paulo” and “Information on the Company—Business Overview—Government Regulation—
Consumer Relations in the State of São Paulo.” 

The  terms  of  our  new  agreement  to  provide  water  and  sewage  services  in  the  city  of  São  Paulo 

could have a material adverse effect on us. 

Our provision of water and sewage services in the city of São Paulo accounted for 55.1% of our gross 
revenues  from  sales  and  services  (excluding  revenues  relating  to  the  construction  of  concession 
infrastructure) in the year ended December 31, 2011. 

On June 23, 2010 the State and the city of São Paulo entered into a convention (convênio) with the 
intermediation and our consent and the consent of the ARSESP pursuant to which they agreed to jointly 
manage  the  planning  of  and  investment  in  the  basic  sanitation  system  of  the  city  of  São  Paulo,  among 
other  things.   This  agreement  established  that  the  State  and  the  city  of  São  Paulo  would  enter  into  an 
agreement with us, granting us exclusive rights with respect to the provision of water and sewage services 
in the city of São Paulo.  In addition, the agreement established the role of the ARSESP in regulating and 
overseeing  our  activities  (including  the  tariffs  we  collect)  and  established  a  management  committee 
(Comitê Gestor) that will be responsible for planning the water and sewage services and for reviewing our 
investment plans.  The management committee will be composed of six members appointed for two year 
terms.  The  State  and  the  city  of  São  Paulo  will  have  the  right  to  appoint  three  members  each.   We  are 
permitted to participate in the meetings of the management committee; however, we are not afforded any 
voting rights  

Also, on June 23, 2010, we entered into a formal agreement with the State and the city of São Paulo 
to  regulate  the  provision  of  these  services.   This  agreement  requires,  among  other  things,  (i)  that  the 
estimated  investments  mentioned  in  the  agreement  comply  with  13%  of  the  gross  revenue  from  the 
municipality of São Paulo, net of the taxes on revenues. The investment plan, upon its execution by us, 
must  be  compatible  with  the  activities  and  programs  included  in  the  sanitation  plan  of  the  State, 
Municipality, and if necessary, of the Metropolitan region. The invest plan is not irrevocable and will be 
reviewed by our management committee every four years, especially the investments  to be executed in 
the subsequent period; and (ii) that we contribute 7.5% of the gross revenues from sales and services we 
obtain from this agreement, net of COFINS and PASEP taxes, to the Municipal Fund for Environmental 
Sanitation  and  Infrastructure  (Fundo  Municipal  de  Saneamento  Ambiental  e  Infraestrutura),  or  the  São 
Paulo  Municipal  Sanitation  Fund,  established  by  Municipal  Law  No.  14,934/2009.   In  addition,  the 
agreement provides that the ARSESP will ensure that the tariffs charged (a) will adequately compensate 
us for the services we provide and (b) can be adjusted to restore the original balance between each party’s 

14 

 
obligation and economic gain (equilíbrio econômico-financeiro).  We currently have an investment plan 
in place that reflects these obligations and addresses their compatibility with the activities and programs 
included in the sanitation plan of the State and of the municipality of São Paulo and, if necessary, the plan 
of  the  metropolitan  region  of  São  Paulo.  This  investment  plan  will  be  reviewed  by  a  management 
committee every four years so as to ensure compliance with government policies and contractual terms.   

Because  we  were  not  previously  required  to  make  the  mandatory  allocations  described  in  items (i) 
and  (ii)  above,  they  were  not  taken  into  account  in  calculating  our  existing  tariff  and  its  adjustment 
formula.   Despite  the  contractual  provisions  and  the  ARSESP’s  role  in  setting  and  adjusting  adequate 
tariffs, which are necessary for our economic and financial balance, we cannot guarantee that the tariffs 
we will be allowed to charge for the provision of water and sewage services in the city of São Paulo will 
continue to adequately compensate us.     

A  decision  of  the  Brazilian  Supreme  Court  regarding  whether  State  or  municipal  governments 
have  the  right  to  execute  concession  and  program  agreements  in  metropolitan  regions  could  have  a 
material adverse effect on us. 

Our  provision  of  water  and  sewage  services  in  the  metropolitan  regions  in  which  we  operate  is 
governed by agreements with the relevant State authorities (other than in the city of São Paulo, where we 
now have an agreement with the municipal authorities as well as the State). In a lawsuit initiated by third 
parties that is currently before the Brazilian Supreme Court, the Court is considering whether the State or 
the  municipal  governments  have  the  proper  authority  to  plan  and  regulate  basic  sanitation  services 
rendered in metropolitan regions, as well as the right to execute concession and program agreements.  If 
the Brazilian Supreme Court grants this authority to municipal governments, under certain circumstances, 
we  may  be  required  to  cease  our  operations  in  certain metropolitan  regions  where we  have  agreements 
with the State only, to the extent that those  municipalities opt to use another water and sewage service 
provider.   To  mitigate  this  risk,  we  have  commenced  a  process  of  executing  agreements  with  both  the 
State  and  the  municipal  governments  of  certain  metropolitan  regions,  and  we  already  have  such 
agreements regarding the city of São Paulo.  We cannot anticipate the effects of the Brazilian Supreme 
Court decision on the provision of our services in other metropolitan regions, which could have a material 
adverse effect on us.  

We have not entered into formal agreements for the provision of water and sewage services with 
certain of the municipalities we serve, including municipalities in metropolitan regions, as required by 
the Basic Sanitation Law, and therefore we may not be able to enforce our rights to continue to provide 
services in these municipalities.  

Under  the  Basic  Sanitation  Law,  we  were  required  to  have  entered  into  formal  agreements  before 
December 31, 2010 with every municipality with which we did not have a formal agreement in place or 
with  which  our  agreements  had  already  expired,  as  is  the  case  of  certain  municipalities  located  in  the 
metropolitan  regions  where  we  are  authorized  to  operate  in  accordance  with  local  legislation.   If  such 
contractual arrangements were not entered into by December 31, 2010, the informal or expired services 
concessions would no longer be valid.  

As of the date of this annual report, of the 363 municipalities we provide water and sewage services 
to,  we  have  informal  or  expired  arrangements  with  99  municipalities.  These  99  concessions  include 
municipalities located in and outside metropolitan regions, including the municipality of Santos, located 
in the coastal region.  Together, these 99 municipalities accounted for 23.8% of our total revenues for the 
year ended December 31, 2011, and 29.7% of our intangible assets as of that same date.   

We  are  currently  negotiating  with  these  municipalities  the  renewal or  the  formalization of  the 
concessions  through  the  execution  of  program  agreements.   In  order  to  renegotiate  or  formalize  the 
agreements, we face the following problems: (i) we are still awaiting the final decision of the Brazilian 
Supreme Court regarding whether the State or the municipalities have the right to enter into contractual 
arrangements  for  the  provision  of  the  basic  sanitation  services  in  the  metropolitan  regions  (until  the 
execution of the agreement with the city and State of São Paulo in June 2010 there was no precedent for a 
joint  management  contractual  arrangement  between  the  State,  the  municipalities  and  us);  (ii)  the 
execution  of  new  agreements  will  depend  on  certain  acts  that  are  beyond  our  control,  such  as  the 
compliance by the municipalities located outside the metropolitan regions with certain legal procedures.  

15 

 
The Basic Sanitation Law did not define any penalty for the non-compliance with the December 31, 
2010 deadline by the municipalities or for the water and sewage service companies in case the deadline is 
not observed.  Consequently, we cannot anticipate if we are going to be subject to any penalty due to the 
lack  of  a  formal  agreement  with  some  municipalities  or  if  any  eventual  penalty  will  have  a  material 
adverse effect on us. 

We  cannot  assure  you  when  or  whether  there  will  be  changes  to  the  conditions  under  which  we 
currently  provide  water  and  sewage  services  to  the  municipalities  with  which  we  do  not  have  formal 
concession agreements or are renegotiating expired agreements, or whether we will be able to continue to 
provide  water  and  sewage  services  in  any  municipalities  where  we  are  unable  to  renew  or  enter  into  a 
formal  concession  agreement.  Because  we  do  not  hold  concessions  or  contractual  rights  to  provide 
services in 99 municipalities, we may not be able to effectively enforce our right to continue to provide 
services therein or may face difficulties in being timely paid for the services that we provide.   

In addition, in the future, our rights in respect of these municipalities could be modified or adversely 
affected by Brazilian federal, state or municipal governmental actions, judicial decisions or other factors.  
For  further  information,  see  “Item  4.B.  Business  Overview—Government  Regulation—The  Basic 
Sanitation  Law”  and  “Item 4.B.  Business  Overview—Government  Regulation—Concessions—Public 
Consortia and Cooperation Agreement Law for Joint Management.”   

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

Our industry is specifically affected by the following risks associated with the provision of water and 

sewage services: 

(cid:131)  we are subject to substantial charges imposed by state and federal government agencies that 

manage water resources related to the abstraction of water from, or dumping of sewage into, water 
bodies, which we may not be able to pass on to our customers.  See “Item 4.B. Business 
Overview—Government Regulation—Water Usage;”   

(cid:131) 

(cid:131) 

(cid:131) 

in some cases, we are required to continue providing services to certain municipalities to which we 
provide water on a wholesale basis that have overdue amounts owed to us and are not paying us on 
a regular basis and we cannot assure you of when or whether these municipalities will pay us in a 
timely manner. See “Item 4.B. Business Overview-Billing Procedures;”    

the degradation of watershed areas may affect the quantity and quality of water available to meet 
our customers’ demand.  See “Item 4.A History and Development of the Company—Capital 
Expenditure Program;”    

 our tariffs may not increase in line with increases in inflation and operating expenses, including 
taxes, or increase in a timely manner, which may hinder us from passing on to our customers 
increases in our cost structure. See “—The terms of our new agreement to provide water and 
sewage services in the city of São Paulo could have a material adverse effect on us”.  These 
constraints may also have an adverse effect on our ability to fund our capital expenditure 
program and financing activities, and to meet our debt service requirements.  See “Item 5.A. 
Operating and Financial Review and Prospects—Factors Affecting Our Results of Operations—
Effects of Tariff Increases;”    

(cid:131)  we are exposed to probable increases in the frequency of extreme weather conditions in the 
future, which may adversely affect both the quality and quantity of waters available for 
abstraction, treatment, and supply. Given that our financial performance is closely linked to 
climate patterns, droughts could adversely affect the water supply systems, resulting in a 
decrease in the volume of water distributed and billed as well as in the revenue derived from 
water supply distribution services.  An increase in heavy rainfalls could impact water quality and 
regular operations of water sources, including abstraction of waters from our dams, due to 
increased soil erosion, silting, pollution and eutrophication of aquatic ecosystems. See “Item 5.A. 
Operating and Financial Review and Prospects—Factors Affecting Our Results of Operations—
Effects of Climate Change (Drought and Intense Rainfalls);” and 

16 

 
  
  
      
  
  
 
   
   
   
(cid:131)  we are dependent upon energy to conduct our operations and eventual shortages or rationing of 
energy may prevent us from providing water and sewage services and may also cause material 
damage to our water and sewage systems when we resume operations. Also, we may not be able 
to pass on to our customers significant increases in energy tariffs. See “Item 4.A. History and 
Development of the Company-Energy Consumption.”

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

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

As of December 31, 2011, we were a provider of water and sewage services to 363 municipalities.  
Between January 1, 2007 and December 31, 2011, we had entered into 30-year agreements with 225 of 
these  municipalities  (including  our  services  agreement  with  the  city  of  São  Paulo),  of  which  25  were 
entered  into  in  2011.   These  225 municipalities  accounted  for  65.2%  of our  total  revenues  for  the  year 
ended December 31, 2011 and 62.6% of our intangible assets as of December 31, 2011.  As of December 
31, 2011, we have been renegotiating 99 concession agreements that expired, including the municipality 
of Santos.  Together, these 99 municipalities accounted for 23.8% of our total revenues for the year ended 
December 31, 2011 and 29.7% of our intangible assets as of that same date. 

From  January  1,  2012  to  2033,  39  concession  agreements  will  expire.   These  39  concession 
agreements accounted for 8.6% of our total revenues for the year ended December 31, 2011 and 6.7% of 
our intangible assets as of that same date.   

We  cannot  assure  you  that  these  municipalities  will  continue  to require our  services  and  enter  into 
new  concession  agreements  or  program  agreements  with  us.   In  the  event  that  we  are  successful  in 
renegotiating  our  concession  agreements  or  entering  into  program  agreements  with  the  municipalities 
whose  concession  agreements  expired  or  will  expire,  we  cannot  assure  you  that  the  new  concession  or 
program  agreements  will  have  the  same  terms  under  which  we  currently  provide  services  to  these 
municipalities.  We cannot make any such assumption because the Basic Sanitation Law prevents us from 
planning,  regulating  and  monitoring  our  services  and  it  requires  more  stringent  control  by  the 
municipalities or by the ARSESP. 

In  addition,  these  municipalities  may  choose  to  assume  the  direct  provision  of  water  and  sewage 
services  or  promote  a  public  bidding  process  to  select  another  water  and  sewage  service  provider.  
Depending  on  the  eligibility  requirements  to  participate  in  the  public  bidding  processes,  we  may  not 
qualify to participate in some or all of these public bidding processes.  If we participate in these public 
bidding processes, we cannot assure you that we will win the bid.  In the event that these municipalities 
assume the direct provision of water and sewage services or promote a public bidding process to select 
another water and sewage service provider, or the new terms or conditions of the concession or program 
agreements  are  less  favorable  to  us,  we  may  be  materially  and  adversely  affected.   See  “Item 4.B. 
Business  Overview—Our  Operations”  and  “Item 4.B.  Business  Overview—Government  Regulation—
Concessions—Public Consortia and Cooperation Agreement Law for Joint Management.”  

Municipalities  may,  under  certain  circumstances,  terminate  our  concessions  before  their 

expiration and the indemnification may be inadequate to recover the full value of our investments. 

The concessions we hold are subject to early termination provisions, which entitle municipalities to 
terminate our concessions prior to their expiration date under certain circumstances.  Municipalities may 
terminate  our  concessions  if  we  fail  to  comply  with  our  obligations  under  the  relevant  concession 
agreement or applicable law, or if the municipality determines, through an expropriation proceeding, that 
terminating  our  concession  prior  to  its  expiration  date  is  in  the  public  interest.   If  any  municipality 
terminates  our  concession  before  the  expiration  date,  we  are  entitled  to  be  indemnified  for  the 
unamortized portion of our investments, but the indemnification may not be sufficient for us to recover 
the full value of our investments.  Further, under the terms of the Constitution of the State of São Paulo, 
municipalities  may  pay  the  indemnification  over  a  term  of  25 years.   However,  the  Brazilian  Supreme 
Court stayed the application of this provision of the Constitution of the State of São Paulo in 1997, and 
the decision remains valid until final judgment. 

17 

 
 
   
In  1997,  the  municipality  of  Santos  enacted  a  law  expropriating  our  water  and  sewage  systems  in 
Santos.   There  are  pending  legal  proceedings  concerning  the  expropriation  carried  out  by  this 
municipality.  We continue to provide water and sewage services to the city of Santos. 

In 1995, the municipality of Diadema terminated the concession agreement that had been entered into 
with us prior  to  the  expiration of  the  concession  agreement.  As  a  result,  we  filed  a  lawsuit  against  the 
municipality  of  Diadema  which  we  eventually  settled  in  1996.   The  municipality  of  Diadema  did  not 
comply with this settlement.  In December 2008, we entered into a memorandum of understanding with 
the  State  of  São  Paulo,  the  municipality  of Diadema  and  the  State  Secretariat  for  Sanitation  and Water 
Resources, formerly known as the State Secretariat for Sanitation and Energy (Secretaria de Saneamento 
e  Energia  do  Estado  de  São  Paulo).   This  memorandum  establishes  our  agreement  to  conclude 
negotiations  and  settle  all  outstanding  amounts  and  stay  the  collection  proceedings we filed  against  the 
municipality  of  Diadema.   In  2011,  the  municipality  of  Diadema  agreed  with  us  to  develop  a  shared 
infrastructure  for  the  provision  of  water  and  sewage  services  through  a  mixed-capital  company  called 
Companhia  de  Agua  e  Esgoto  de  Diadema,  or  CAED,  and  we  cannot  predict  when  this  company  will 
begin operations.  The amount owed to us by the Diadema municipality would be returned to us through 
our  capital  participation  in  CAED.   We  can  give  no  assurance  that  we  will  recover  our  investments  in 
such company.   

For  further  information  on  these  lawsuits,  see  “Item 8.A.  Financial  Information—Consolidated 

Statements and Other Financial Information—Legal Proceedings.” 

We cannot assure you that other municipalities will not seek to terminate their concession agreements 
before the contractual expiration date.  The early termination of concession agreements by municipalities, 
our  inability  to  receive  adequate  indemnification  for  the  investments  we  made,  or  the  payment  of 
indemnification due to us over a long period, may have a material adverse effect on us. 

The  Basic  Sanitation  Law  has  established  provisions  governing  the  indemnification  of  water  and 
sewage  service  providers  in  case  of  early  termination  of  concession  agreements  by  a  municipality  and 
reduced  the  term  over  which  indemnification  must  be  paid  to  four  years.   These  provisions  are  also 
applicable to concession agreements entered into prior to the enactment of the Basic Sanitation Law, as 
long as these concession agreements do not have a contractual indemnification provision in case of early 
termination or we have not otherwise entered into an agreement with the municipality with regard to such 
early  termination.   Nevertheless,  we  cannot  anticipate  the  effects  of  the  Basic  Sanitation  Law  on  the 
amount of, and enforceability of the right to, indemnification and how Brazilian courts will enforce the 
provisions of the Basic Sanitation Law. 

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

expenditure program. 

Our  capital  expenditure  program  will  require  substantial  liquidity  and  capital  resources  of 
approximately R$7.9 billion in the period from 2012 through 2015.  We recorded R$2.4 billion of capital 
expenditure in 2011 in connection with our capital expenditure program. 

We have funded in the past, and we plan to continue to fund these expenditures with funds generated 
by operations and domestic and foreign currency borrowings on acceptable terms.  A significant portion 
of  our  financing  needs  have  been  funded  by  lenders  controlled  by  the  federal  government.   We  also 
benefit from long-term financing from 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 meet our obligations or finance our capital expenditure program, which could 
have a material adverse effect on us.  

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

18 

 
We are also subject to financial covenants limiting our ability to incur additional indebtedness, which 
could  have  a  material  adverse  effect  on  us.   For  further  information  on  these  covenants,  see  “Item 5.B. 
Liquidity  and  Capital  Resources—Capital  Sources—Indebtedness  Financing—Financial  Covenants.”  
Our  failure  to  comply  with  these  covenants  could  impair  our  ability  to  finance  our  capital  expenditure 
program, which could have a material adverse effect on us.  

We  are  subject  to  cost  increases  to  comply  with  environmental  law  requirements  and  potential 

environmental liability that could have a material adverse effect on us. 

Our  facilities  are  subject  to  extensive  Brazilian  federal,  state  and  municipal  laws  and  regulations 
relating  to  the  protection  of  human  health  and  the  environment.   These  laws  and  regulations  establish 
potability  standards  for  consumption  and  limit  or  prohibit  emissions  or  spills  of  effluents,  such  as  raw 
sewage,  produced  in  connection  with  our  operations.   We  could  be  subject  to  civil  public  actions  and 
criminal,  administrative  and  other  civil  proceedings  for  non-compliance  with  environmental  laws  and 
regulations, which could expose us to administrative and civil penalties and criminal sanctions, such as 
fines,  closure  orders  and  significant  indemnification  obligations.   Since  environmental  laws  and  their 
enforcement by Brazilian authorities are becoming more stringent, our capital expenditures and expenses 
for  environmental  compliance  may  increase  substantially.   Expenditures  required  for  compliance  with 
environmental laws and regulations may result in reductions in other strategic investments that we have 
planned,  which  could  negatively  affect  us.   In  addition,  due  to  more  stringent  enforcement  of 
environmental laws by Brazilian courts, we may be required to pay substantial fines and indemnifications 
in amounts that may vary widely from those currently anticipated.  We are presently a party to a number 
of  civil  public  actions and  administrative  proceedings related  to  environmental  matters,  with  regard  to 
which we are unable to calculate our estimated amount of potential liability.  Any unfavorable judgment 
in  relation  to  these  lawsuits  and  proceedings  or  any  material  unforeseen  environmental  liabilities  may 
have a material adverse effect on us.  For further information on these lawsuits, see “Item 8.A. Financial 
Information—Consolidated Statements and Other Financial Information—Legal Proceedings.”   

The  enactment  of  new  laws  and  regulations  relating  to  climate  change  and  changes  in  existing 
regulation,  as  well  as  the  physical  effects  of  climate  change,  may  result  in  increased  liabilities  and 
increased capital expenditures, which could have a material adverse effect on us. 

As  new  laws  and  regulations  relating  to  climate  change,  including  carbon  controls,  become 
applicable  to  us,  and  as  existing  environmental  regulations  relating  to  climate  change  become  more 
stringent, it is possible that our capital expenditure for compliance with these laws and regulations will 
increase  substantially  in  the  future.   If  we  increase  capital  expenditure  to  comply  with  these  laws  and 
regulations, we may be required to reduce expenditure on other strategic investments. 

In addition, if climate change leads to significant physical effects, such as variations in the intensity 
of droughts and rain, our services may be affected and we may be required, among other things, to:  (i) 
make significant investments in seeking new water sources located further from major consumer centers 
and (ii) make significant investments in new technologies. 

We have not adopted any method for calculating the investments that would be necessary in the event 
of a  significant  physical  effect  from  climate  change.  Any  substantial  increase  in  expenditure related  to 
climate change, whether for compliance with environmental regulations or for preventing or remedying 
the physical effects of climate change, may have a material adverse effect on us.  See “Item 4.B. Business 
Overview—Environmental  Matters—Climate  Change  Regulations:   Reduction  of  Greenhouse  Gases 
(GHG).” 

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

effect on us.  

We are a party to a number of legal proceedings involving significant monetary claims.  These legal 
proceedings include, among others, civil, environmental, tax, labor, condemnation and other proceedings.  
As  of  December 31,  2011,  the  total  value  of  all  outstanding  claims  was  R$24,152.0  million  (net  of 
R$133.1 million in court deposits).  A substantial monetary judgment against us in one or more of these 
legal proceedings may have a material adverse effect on us.  Based on advice from our legal counsel, we 
have  provisioned  a  total  aggregate  amount  of  R$1,571.8  million  (net  of  court  deposits)  as  of 
December 31, 2011 to cover probable losses related to legal proceedings.  This provision does not cover 

19 

 
all legal proceedings involving monetary claims filed against us and it may be insufficient to cover our 
liabilities related to these claims.   

Any unfavorable judgment in relation to these proceedings may have a material adverse effect on us.  
For  more  information,  see  “Item 8.A.  Financial  Information—Consolidated  Statements  and  Other 
Financial Information—Legal Proceedings.” 

Risks Relating to Our Common Shares and ADSs 

The  relative  volatility  and  illiquidity  of  the  Brazilian  securities  markets  may  substantially  limit 

your ability to sell our common shares underlying the ADSs at the price and time you desire. 

Investing in securities that trade in emerging markets, such as Brazil, often involves greater risk than 
investing in securities of issuers in major securities markets, and these investments are often considered to 
be more speculative in nature.  The Brazilian securities market is substantially smaller, less liquid, more 
concentrated  and  can  be  more  volatile  than  major  securities  markets.   Accordingly,  although  you  are 
entitled  to  withdraw  the  common  shares  underlying  the  ADSs  from  the  depositary  at  any  time,  your 
ability to sell the common shares underlying the ADSs at a price and time at which you wish to do so may 
be  substantially  limited.   There  is  also  significantly  greater  concentration  in  the  Brazilian  securities 
market  than  in  major  securities  markets.   The  ten  largest  companies  in  terms  of  market  capitalization 
represented  approximately  53.1%  of  the  aggregate  market  capitalization  of  the  BM&FBOVESPA  as  of 
December 31, 2011.  The top ten stocks in terms of trading volume accounted for approximately 50.4%, 
48.8% and 47.0% of all shares traded on the BM&FBOVESPA in 2009, 2010 and 2011, respectively.    

Investors who exchange ADSs for common shares may lose their ability to remit foreign currency 

abroad and to obtain Brazilian tax advantages. 

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

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

A holder of common shares or ADSs may face difficulties in protecting his or her interests as a 

shareholder because we are a Brazilian mixed capital company. 

We are a mixed capital company (sociedade de economia mista) organized under the laws of Brazil, 
and all of our directors and officers and our controlling shareholder reside in Brazil.  All of our 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 

20 

 
to our ability to render public services are subject to seizure or attachment.  Furthermore, the execution of 
a judgment against our controlling shareholder may be delayed as payment of the judgment must be made 
pursuant to the State’s budget in a subsequent fiscal year.  None of the public property of our controlling 
shareholder is subject to seizure or attachment, either prior to or after judgment.  

Mandatory arbitration provisions in our bylaws may limit the ability of a holder of our ADSs to 

enforce liability under U.S. securities laws. 

Under our bylaws, any disputes among us, our shareholders and our management with respect to the 
application  of  Novo  Mercado  rules,  Brazilian  Corporate  Law  and  the  application  of  the  rules  and 
regulations regarding Brazilian capital markets will be resolved by arbitration conducted pursuant to the 
BM&FBOVESPA  Arbitration  Rules  in  the  Market  Arbitration  Chamber.   Any  disputes  among 
shareholders,  including  ADR  holders,  and  disputes  between  us  and  our  shareholders,  including  ADR 
holders, will also be submitted to arbitration.  As a result, a court in the United States might require that a 
claim brought by an ADR holder predicated upon the U.S. securities laws be submitted to arbitration in 
accordance  with  our  bylaws.   In  that  event,  a  purchaser  of  ADSs  would  be  effectively  precluded  from 
pursuing remedies under the U.S. securities laws in the U.S. courts.   

A holder of our common shares and ADSs might be unable to exercise preemptive rights and tag-

along rights with respect to the common shares. 

U.S. holders of common shares and ADSs may not be able to exercise the preemptive rights and tag-
along  rights  relating  to  common  shares  unless  a  registration  statement  under  the  U.S.  Securities  Act  of 
1933, as amended, or the Securities Act, 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,  an  ADR  holder  may  receive  only  the  net  proceeds  from  the  sale  of  his  or  her 
preemptive  rights  and  tag-along  rights  or,  if  these  rights  cannot  be  sold,  they  will  lapse  and  the  ADR 
holder will receive no value for them. 

A holder of our ADSs may find it more difficult than a holder of our common shares to exercise 

his or her voting rights at our shareholders’ meetings. 

Holders may exercise voting rights with respect to the common shares represented by our ADSs only 
in accordance with the deposit agreement relating to our ADSs.  There are no provisions under Brazilian 
law  or  under  our  bylaws  that  limit  the  exercise  by  ADR  holders  of  their  voting  rights  through  the 
depositary with respect to the underlying common shares.  However, there are practical limitations upon 
the ability of ADR holders to exercise their voting rights due to the additional procedural steps involved 
in  communicating  with  these  holders.   For  example,  our  common  shareholders  will  receive  notice  of 
shareholders’ meetings through publication of a notice in an official government publication in Brazil and 
will be able to exercise their voting rights by either attending the meeting in person or voting by proxy.  
ADR  holders, by  comparison,  will  not  receive  notice  directly  from  us.   Instead,  in  accordance  with  the 
deposit agreement, we will provide the notice to the depositary, which will, in turn, as soon as practicable 
thereafter  mail  to  ADR  holders  the  notice  of  the  meeting  and  a  statement  as  to  the  manner  in  which 
instructions may be given by holders, but only if we request the depositary to do so.  To exercise their 
voting rights, ADR holders must then instruct the depositary as to voting the common shares represented 
by their ADSs.  Due to these procedural steps involving the depositary, the process for exercising voting 
rights  may  take  longer  for  ADR  holders  than  for  holders  of  common  shares.   ADSs  for  which  the 
depositary fails to receive timely voting instructions will not be voted at any meeting. 
ITEM 4.        INFORMATION ON THE COMPANY 
A.    History and Development of the Company 

Overview 

Companhia de Saneamento Básico do Estado de São Paulo – SABESP is a mixed capital company 
(sociedade de economia mista) with limited liability.  We were incorporated on September 6, 1973 under 
the laws of the Federative Republic of Brazil.  We are registered at the Commercial Registry of the State 
of São Paulo (Junta Comercial do Estado de São Paulo) under registration number NIRE 35300016831.  
Our principal executive offices are located at Rua Costa Carvalho, 300, 05429-900 São Paulo, SP, Brazil.  

21 

 
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 818 West Seventh Street – Team 1, Los Angeles, CA 90017.  We are 
allowed to operate, in a subsidiary form, in other Brazilian locations and abroad.  See “Item 4.B. Business 
Overview—Government  Regulation—Concessions—Public  Consortia  and  Cooperation  Agreement  Law 
for Joint Management.”  

We believe we are one of the largest water and sewage service providers in the world (based on the 
number  of  customers  in  2011),  according  to  the  13th  edition  of  the  Pinsent  Masons  Water  Yearbook 
(2011-2012).  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 IBGE, the State of São Paulo is Brazil’s  most 
populous  state  and  the  state  with  the  highest  gross  domestic  product,  or  GDP,  in  Brazil.   For  the  year 
ended  December 31,  2011,  from  our  total  revenues  we  had  a  consolidated  net  revenue  of  R$9,941.6 
million  and  a  consolidated  net  income  of  R$1,223.4  million.   Our  total  consolidated  assets  was 
R$25,215.0 million and our total shareholders’ equity was R$10,545.9 million as of December 31, 2011.  

As of December  31, 2011, we  provided  water  and  sewage  services  to  a  broad  range  of  residential, 
commercial, industrial and governmental customers in 363 of the 645 municipalities in the State of São 
Paulo, including the city of São Paulo.  Substantially all of our concessions or program agreements have 
30-year  terms.   99  of  these  concessions  have  expired  and  are  currently  being  renegotiated.   From 
January 1, 2012 through 2033, 39 concessions will expire, which we will seek to replace with program 
agreements.  

We also supply water on a wholesale basis to six municipalities located in the São Paulo metropolitan 
region and to the municipality of Sumaré (with a total estimated urban population of approximately 3.7 
million), in which we do not operate water distribution systems.  Within these municipalities, five of them 
utilize our sewage treatment services.  For the year ended December 31, 2011, the São Paulo metropolitan 
region (including the municipalities to which we provide water on a wholesale basis) and the Regional 
Systems  accounted  for  73.9%  and  26.1%  of  our  gross  revenue  from  sales  and  services  (excluding 
revenues relating to the construction of concession infrastructure), respectively. 

As  of  December 31,  2011,  we  provided  water  services  through  7.5  million  water  connections  to 
approximately  23.9 million  people,  representing  approximately  59.0%  of  the  urban  population  of  the 
State  of  São  Paulo,  and  effectively  had  a water  coverage ratio  of  approximately  100%  in  respect  of  all 
regions.   As  of  that  date,  we  provided  sewage  services  through  5.9  million  sewage  connections  to 
approximately  20.5  million  people  and  effectively  had  a  sewage  coverage  ratio  of  82.0%.   As  of 
December 31, 2011, we operated through 66,389 kilometers of water pipes and mains and through 45,073 
 kilometers of sewer lines.   

We also provide water and/or sewage services to four other municipalities through special purpose 
companies.  In addition, we render consulting services related to the rational use of water and commercial 
and operational management in Panama and Honduras through a partnership with Latin Consult. 

The  State,  our  controlling  shareholder,  is  required  by  law  to  own  at  least  50%  plus  one  of  our 
common shares.  As of April 23, 2011, the State owned 50.3% of our outstanding common shares.  As a 
mixed  capital  company,  we  are  an  integral  part  of  the  State  governmental  structure.   Our  strategy  and 
major policy decisions are formulated in conjunction with the State Secretariat for Sanitation and Water 
Resources  as  part  of  the  overall  strategic  planning  for  the  State.   The  majority  of  the  members  of  our 
board of directors and our board of executive officers are nominated by the State government. 

In  addition,  our  capital  expenditure  budget  is  subject  to  approval  by  the  State  legislature  and  is 
approved in conjunction with the budget of the State Secretariat for Sanitation and Water Resources as a 
whole.  Our consolidated financial statements and accounting records are subject to review by the State 
Accounts Tribunal (Tribunal de Contas), as are all accounts of the State. 

Our Strengths 

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

Well-established business with significant size, scale and know-how to operate in complex urban 
settings.   We  believe  we  are  one  of  the  largest  water  and  sewage  service  providers  in  the  world.   We 
provide  water  services  directly  to  approximately  23.9 million  people  and  supply  water  on  a  wholesale 
basis to an additional urban population of 3.7 million people.  As of December 31, 2011, we effectively 

22 

 
had a water coverage ratio of approximately 100% in respect of all regions in which we operate.  We also 
provide sewage services directly to approximately 20.5 million people, achieving a sewage coverage ratio 
of 82.0% in respect of all regions in which we operate as of December 31, 2011.  During the year ended 
December 31, 2011, our net revenue from sales and services increased by 7.7% as compared to the year 
ended December 31, 2010 (including revenues relating to the construction of concession infrastructure).  
Our  significant  size  and  scale  have  required  us  to  operate  in  complex  urban  settings  such  as  favelas   
(shantytowns)  and  environments  without  urban  planning,  which  has  enabled  us  to  develop  skills  to 
operate in adverse conditions and have well-trained personnel and a specialized structure that we believe 
our competitors lack.  

Operations in Brazil’s most populous and wealthy state.  The State of São Paulo, part of the most 
developed  and  economically  active  region  of  Brazil,  is  the  most  populous  state  in  Brazil,  with  an 
estimated population of 43.0 million as of December 31, 2011.  The city of São Paulo had an estimated 
population  of  11.0  million  as  of  that  date,  with  20.4  million  inhabitants  in  the  São  Paulo  metropolitan 
region.  Based on its GDP, the State of São Paulo is the wealthiest state and largest economy in Brazil.  
The GDP of the State of São Paulo was approximately R$1.1 trillion in 2009, representing approximately 
33%  of  Brazil’s  total  GDP.   The  State  of  São  Paulo  generates  more  revenue  from  water  and  sewage 
services than any other Brazilian state.   

Strong Contract Log.  From the 363 municipalities we serve, in the last five years, we have executed 
30-year agreements with 225 of them, including an agreement with the municipality of São Paulo entered 
into in June 2010.  As of December 31, 2011, the income from those 225 municipalities in which we have 
long-term contracts accounted for 65.2% of our revenues.   

Access  to  low-cost  and  diverse  sources  of  financing.   Our  strong  cash  flow  generation  from 
operations  and  our  role  as  an  essential  public  service  provider  places  us  in  a  privileged  position  in  our 
industry  to  obtain  low  cost,  long-term  financing  from  Brazilian  public  banks,  and  domestic  and 
international  multilateral  agencies  and  development  banks.   In  addition,  we  are  not  dependent  upon  a 
limited  number  of  sources  of  financing.   We  benefit  from  various  funding  alternatives  available  in  the 
Brazilian and international markets for our working capital needs and our capital expenditure programs.   

Strong  corporate  governance  practices.   In  2002,  we  joined  the  Novo  Mercado  segment  of  the 
BM&FBOVESPA,  which  is  the  listing  segment  in  Brazil  with  the  highest  corporate  governance 
requirements.   As  a  result,  we  are  committed  to  maintaining  certain  additional  corporate  governance 
practices that are not required by Brazilian law, ensuring additional protection to our shareholders rights 
and enhancing the quality of information we disclose to the market.  On December 1, 2007, we became 
part of the BM&FBOVESPA Corporate Sustainability Index, or ISE, which reflects our high degree of 
commitment to sustainable environmental and social practices.   

High quality operations.  We believe that we adhere to high standards of service and utilize the best 
available technology in the sanitation business to control the quality of the water captured, produced and 
distributed.  All of our water quality control laboratories operate in accordance with the ABNT NBR ISO 
9001,  which  follows  the  highest  international  water  quality  standards.   In  addition  to  our  central 
laboratory,  11  of  our  regional  laboratories  are  accredited  by  the  National  Institute  of  Metrology, 
Standardization  and Industrial  Quality,  or INMETRO,  thereby  assuring  the  quality  and  accuracy of our 
test results, according to ABNT NBR ISO IEC 17025.  Moreover, our laboratories and field teams use the 
latest equipment to detect substances controlled by regulations and have highly trained teams to handle 
contingencies and customer complaints.  We believe our technology enhances the efficiency and quality 
of our operations.  As of December 31, 2011, 50 of our sewage treatment facilities had obtained the ISO 
14001 certification. 

Our Strategy 

Our mission is to provide water and sewage services, contributing to the improvement of the quality 
of life and of the environment.  To this end, our strategic objectives are based upon the guiding principles 
of  growth,  quality,  universalization  of  sanitation  services  and  social,  economic  and  environmental 
sustainability,  while  focusing  on  reaching  excellence  on  costumer  service.   We  also  base  our  strategic 
objectives on our political and institutional relationships as well as on our commitment to the market to 
increase  shareholder  value.   We  seek  to  implement  these  guiding  principles  through  the  following 
strategies: 

23 

 
Continue  to  seek  growth  while  improving  our  financial  results  by  reducing  operating  costs, 
increasing productivity and profitability and prudently managing our levels of indebtedness.  We aim 
to apply our principles of financial growth and sustainability to each business unit, assigning goals and 
setting clear responsibilities to each unit so as to reach better financial results.  To achieve this goal, we 
intend  to  use  our  best  efforts  to  reduce  operating  costs  and  increase  productivity  and  profitability.   We 
plan  to  improve  the  management  of  our  assets,  as  well  as  to  continue  to  reduce  our  total  operating 
expenses  by  automating  some  of  our  facilities,  streamlining  operational  processes,  implementing 
integrated  planning  and  further  investing  in  internal  technological  research  and  development.   We  also 
plan to continue our efforts to improve our collection of overdue accounts receivable from municipalities 
to which we provide services, from the State and from other governmental entities, including by exploring 
opportunities to offset these outstanding debts against certain possessory or property rights over utilities 
relating  to  water  and  sewage  systems.   We  intend  to  continue  to  fund  our  working  capital  needs  and 
estimated  capital  expenditure  programs  with  diversified  sources  of  financing,  such  as  domestic  and 
international  development  banks  and  multilateral  agencies.   We  will  continue  to  seek  market 
opportunities for low-cost financing and restructuring of our indebtedness if and when advantageous and 
appropriate.   

Improve  operating  efficiency  and  reduce  water  losses.   We  seek  to  reduce  both  physical  water 
losses, which result mainly from leakage, and non-physical water losses, which result primarily from the 
inaccuracy of our water meters installed at our customers’ premises and at our water treatment facilities, 
and  from  clandestine  and  illegal  use.   In  order  to  achieve  more  consistent  long-term  results,  we  have 
developed a comprehensive 11-year program to reduce our water loss rate.  The first three years of the 
program from 2009 to 2011 was funded by the BNDES.  During 2012 to 2016 the program is being also 
funded  by  a  loan  granted  by  the  government  of  Japan  through  the  Japan  International  Cooperation 
Agency, or JICA.  The program’s focus is on the renewal of our water distribution infrastructure and the 
improvement of maintenance and control services as a means of reducing physical water losses.  We are 
also  seeking  to  reduce  physical  water  losses  by  creating  smaller  water  supply  districts  through  the 
construction  of  district  metering  areas,  or  DMAs,  that  reduce  the  system’s  pressure  and  pipe  bursts, 
allowing  leaks  to  be  detected  and  repaired  more  efficiently.   The  program  also  seeks  to  reduce  non-
physical water losses by upgrading and replacing inaccurate water meters and through inspections of non-
authorized water consumption in water service connections. 

Ensure  the  quality  and  availability  of  our  services  in  our  existing  service  area.   Our  goal  is  to 
maintain an effective water coverage ratio of around 100%, coupled with a high standard of quality and 
availability and meet the expected population growth by adding 1.3 million water connections from 2012 
to  2019.   We  also  intend  to  increase  our  sewage  coverage  ratio  to  95%  by  2019  by  adding  1.8  million 
sewage  connections.   In  addition,  we  are  also  developing  short,  medium  and  long-term  marketing 
strategies, such as client segmentation and tailor-made solutions for each type of client, which we believe 
will  help  us  increase  our  customer  base.   We  also  seek  to  improve  our  costumer  support  strategies  by 
modernizing  our  telephone  and  internet-based  costumer  support  and  continuously  measure  the  level  of 
satisfaction of our clients.  

Maintain and continue to expand our existing service areas.  We intend to maintain our operating 
base  through  the  execution  of  new  agreements.   To  this  end,  we  are  actively  seeking  to  develop  closer 
relationships  with  the  municipal  governments  that  we  currently  serve  in  order  to  increase  customer 
loyalty and thereby renew all or substantially all our expiring concession agreements.  In June 2010, we 
entered into an agreement with the State and city of São Paulo with a 30-year term for the provision of 
water  and  sewage  services  in  the  city  of  São  Paulo,  which  in  the  year  ended  December 31,  2011 
accounted  for  55.1%  of  our  gross  revenues from  sales  and  services  (excluding  revenues  relating  to  the 
construction of concession infrastructure).  Between January 1, 2007 and December 31, 2011, we entered 
into 225  agreements  with 30-year  terms  with  municipalities  (including our  services  agreement  with  the 
city of São Paulo), of which 25 were entered into in 2011.  These 25 municipalities accounted for 2.9% of 
our total revenues for the year ended December 31, 2011 and 3.3% of our intangible assets as of that same 
date.  As of December 31, 2011, 99 of our concessions had expired and are currently being renegotiated.  
These 99 municipalities accounted for 23.8% of our total revenues for the year ended December 31, 2011 
and  29.7%  of  our  intangible  assets  as  of  that  same  date.   From  January  1,  2012  through  2033,  39 
concession agreements accounting for 8.6% of our revenues for the year ended December 31, 2011 and 
6.7% of our intangible assets as of December 31, 2011 will expire.   

We have also developed a platform to offer unique services relating to sustainability, environmental 
preservation  and  water  resource  management  to  our  large  industrial,  commercial  and  residential 

24 

 
customers in order to encourage these customers to continue to use our water services.  We also intend to 
continue  to  expand  our  sewage  services.   A  significant  portion  of  our  capital  expenditure  program,  of 
approximately R$7.9 billion between 2012 and 2015, is designed to achieve this goal.  We also regularly 
explore  the  possibility  of  executing  agreements  for  the  provision  of  water  and  sewage  services  in 
municipalities  of  the  State  of  São  Paulo  in  which  we  currently  have  no  operations  or  to  which  we 
currently  supply  water  and  provide  sewage  treatment  solely  on  a  wholesale  basis,  representing  a  total 
population  of  approximately  17  million.   We  evaluate  possible  expansion  opportunities  in  terms  of 
proximity  to  our  existing  service  areas  to  maximize  return  on  investment  and  improve  our  financial 
performance.  We also intend to study, and take advantage of, opportunities in other Brazilian states and 
in other countries to expand our services and increase our market share. 

Expand  our  water  and  sewage  services.   We  had  a  sewage  coverage  ratio  of  82.0%  as  of 
December 31, 2011, and we plan to increase our sewage coverage ratio to 95% by 2019, by adding over 
1.8  million  sewage  connections.   In  addition,  there  are  municipalities  in  the  State  of  São  Paulo 
representing an aggregate population of approximately 17 million to which we currently do not provide 
water or sewage services, or to which we currently supply water solely on a wholesale basis.  Our strong 
presence  in  the  State  and  experience  in  providing  water  and  sewage  services  places  us  in  a  privileged 
position to expand our sewage services to municipalities in which we provide only water services and our 
water and sewage services to municipalities in which we do not yet operate, in both the State of São Paulo 
and also in other states in Brazil and abroad.  Further, we seek to deepen our relationships with strategic 
clients that consume high volumes of water (more than 500 cubic meters per month) by applying special 
tariffs for these clients.  

Seek selective opportunities to expand our business.  In 2007, a change in our bylaws expanded the 
scope  of  our  corporate  purpose  to  include  activities  complementary  to  our  water  and  sewage  services, 
such  as  urban  rainwater  management  and  drainage  services,  urban  cleaning  services  and  solid  waste 
management services.  Since then we have: 

(cid:131)  executed cooperation agreements to exchange technology with six regional basic sanitation 

companies in Brazil, as well as with international businesses such as Mekorot National Water 
Company, an Israeli company, Sociedade General Aguas de Barcelona S/A – Agbar, a Spanish 
company, Instituto Costarricence de Acueductos y Alcantarillados, a Costa Rican company,  
Empresa Pública de Medellin, a Colombian municipal multi-utilities company and Agua y 
Saneamientos Argentinos - AYSA, an Argentine company, which will allow us to exchange know-
how and learn about future opportunities;

(cid:131)  executed memoranda of understanding with three municipalities to study the possibility of 

operating landfills; 

(cid:131)  created four special purpose companies (SESAMM – Serviços de Saneamento de Mogi Mirim S/A; 
Águas de Castilho S.A.; Águas de Andradina S.A.; and Saneaqua Mairinque S.A.) to operate water 
and/or sewage concessions granted by four municipalities in the State of São Paulo; 

(cid:131)  executed an agreement with the Servitec/Tecniplan consortium for the use of small hydroelectric 

power plants in our water treatment stations in Guaraú and Vertedouro Cascata; 

(cid:131)  executed an agreement with the basic sanitation company of the state of Alagoas to transfer 

technology for the reduction of water losses in the city of Maceió;

(cid:131)  executed a service agreement with the basic sanitation company of the state of Espírito Santo to 
license the use of our proprietary software “Aqualog” designed to remotely monitor water 
treatment; 

(cid:131)  won two international public biddings for the provision of:  (i) consulting services relating to a 

program for the rational use of water and for the implementation of a new model for commercial 
and operational management of the Instituto de Acueductos y Alcantarillados Nacionales, the 
company responsible for the provision of the water and sewage services in the central provinces of 
Panama, and (ii) consulting services for the implementation of a new model for commercial and 

25 

 
  
  
  
   
  
   
  
  
  
  
  
  
  
   
operational management in nine municipalities of Honduras; 

(cid:131)  created a special purpose company (Aquapolo Ambiental S.A.), in partnership with a private 

sanitation services operator, to build and operate the largest water recycling facility in the southern 
hemisphere, which will supply up to 1,000 liters per second to industries in the São Paulo 
metropolitan region; 

(cid:131) 

rendered consulting services relating to the Municipal Basic Sanitation Plan to the municipality of 
Barro Alto, located in the State of Goiás; and

(cid:131)  created a special purpose company (ATTEND), in partnership with Estre Ambiental S.A., for the 
implementation of a structure to receive non-domestic water resources in the municipality of São 
Paulo, which will also have a pre-treatment water station.

In addition, in connection with the expansion of our business, we are evaluating and may consider 

creating an investment vehicle, Sabesp Participações, through which we may make equity investments.   

We intend to continue to selectively seek new business opportunities to take advantage of our know-

how, size and scale. 

Establish efficient and competitive ways of attracting, retaining and motivating our personnel.  We 
intend  to  become  a  reference  in  human  resource  management,  providing  our  personnel  with  growth 
opportunities  and  recognition.   We  seek  to  raise  workplace  satisfaction  levels  by  establishing  programs 
for the professional and personal development of employees, particularly of those in managerial positions, 
setting attractive compensation packages and creating a healthy and collaborative work environment.  

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

State of São Paulo 

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

The State of São Paulo occupies 3.0% of Brazil’s land mass and encompasses an area amounting to 
approximately 96,000 square miles.  According to the SEADE, the State of São Paulo had an estimated 
total population of 43.0 million as of December 31, 2011.  The city of São Paulo, the State of São Paulo’s 
capital,  had  an  estimated  population  of  11.0  million,  with  20.4  million  inhabitants  in  the  São  Paulo 
metropolitan region, as of December 31, 2011.  The São Paulo metropolitan region encompasses 39 cities 
and  is  the  largest  metropolitan  region  in  the  Americas  and  the  third  largest  metropolitan  region  in  the 
world,  according  to  the  United Nations’ World  Urbanization Prospects, 2009  Revision.   The  São  Paulo 
metropolitan region accounted for approximately 47% of the population of the State of São Paulo as of 
December 31, 2011.  

According to the IBGE, the GDP of the State of São Paulo was approximately R$1.1 trillion in 2009, 
representing approximately 33% of Brazil’s total GDP, and making it the largest economy of any state in 
Brazil based on GDP.  According to the IBGE, the State of São Paulo is also the leading Brazilian state in 
terms  of  manufacturing  and  industrial  activity,  with  a  strong  position  in  car  manufacturing, 
pharmaceuticals, computer manufacturing, steel making and plastics, among other activities, as well as a 
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  nineteenth  century,  water  and  sewage  services  in  the  State  of  São  Paulo  were 
generally provided by private companies.  In 1875, the Province of São Paulo granted a concession for the 
rendering  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 rendering of water and sewage 
services  from  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 State government.  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 State 
government  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  Water  Company  of  the  São  Paulo  Metropolitan  Region 
(Companhia  Metropolitana  de  Água  de  São  Paulo),  or  the  COMASP,  the  purpose  of  which  was  to 
provide potable water on a wholesale basis for public consumption in the municipalities of 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 Superintendence of Water and Sewers of the city of São Paulo (Superintendência de Água e Esgoto da 
Capital), or the SAEC, was created by the State government to distribute water and collect sewage in the 
city  of  São  Paulo.   All  assets  previously  owned  by  the Department  of  Water  and  Sewers  in  connection 
with  the  water  services  were  transferred  to  the  SAEC.   Also  in  1970,  the  State  created  the  Basic 
Sanitation Company of the São Paulo Metropolitan Region (Companhia Metropolitana de Saneamento de 
São Paulo), or the 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  the  sewage 
services  were  transferred  to  the  SANESP.   The  Department  of  Water  and  Sewers  was  subsequently 
closed. 

On June 29, 1973, pursuant to State Law n. 119, COMASP, the SAEC and the 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).   We  were 
incorporated under the laws of Brazil as a limited company (sociedade anônima), for indefinite duration.  
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 and the State has been our controlling shareholder as required by State Law n. 119.  We thus have 
been  integrated  into  the  State   governmental  structure  and  our  strategies  have  been  formulated  in 
conjunction  with  the  strategies  for  the  State  Department  of  Water  Resources  and  Sanitation.  
Additionally, most members of our Board of Directors and our management are appointed by the State 
Government. 

The budget for our capital expenditures is subject to approval of the State legislative chamber. This 
approval is obtained simultaneously with the approval of the budgets of the Department of Sanitation, of 
the Department of Energy and of the State of São Paulo. The Company is also subject to supervision from 
the Court of Audit of the State of São Paulo (“Tribunal de Contas do Estado de São Paulo”), with regard 
to our accounting, financial, budgetary, operational and assets. 

We provide water and sewage services directly to a large number of residential, commercial and 
industrial private consumers, on top of to a variety of public entities in 363 of the 645 municipalities in 
the State, including in the city of São Paulo, as well as providing treated water on a wholesale basis to six 
municipalities located in the São Paulo metropolitan region and to the municipality of Sumaré, in which 

27 

 
we do not operate the distribution systems to consumers. Among these municipalities, we also provide 
sewage treatment services to five of them. Currently, we are a leading provider of water and sewage 
services in the world in number of clients, according to the 13th edition of the Pinsent Masons Water 
Yearbook (2011-2012). 

In 1994, we were registered with the CVM as a publically-held company subject to rules issued by 

the CVM, including those relating to the periodic disclosure of extraordinary facts or relevant events.  
Our common shares have been listed on the BM&FBOVESPA under the ticker “SBSP3” since June 4, 
1997. 

In 2002, we joined the Novo Mercado segment of the BM&FBOVESPA, which is the listing segment 

in Brazil with the highest corporate governance requirements.  During that same year, we registered our 
securities with the Securities and Exchange Commission, or SEC, and started trading our shares in form 
of American Depositary Receipts – level III (“ADRs”) on the New York Stock Exchange, or NYSE.  

In 2004, a secondary offer of common shares held by the State of São Paulo was made 

simultaneously in the Brazilian and in the international market. On December 1, 2007, we became part of 
the BM&FBOVESPA Corporate Sustainability Index, or ISE, which reflects our high degree of 
commitment to sustainable environmental and social practices. 

In December, 2007, Law No. 1,025 allowed for the creation of regulatory agencies for the 
supervision of water and sewage services. The same law created ARSESP, the regulatory agency that 
regulates and supervises the services we provide. 

In July 2008, we announced that we would expand the area reached by our services, as well as 
including in our scope of services activities related to environmental and energy solutions, as required by 
the State Law No. 1,025. Since then, we have also been forming partnerships with private companies to 
consolidate our operations in the sanitation sector, in particular: (i) through a special purpose entity which 
provides services of water distribution and/or sewage treatment for certain municipalities in the State; (ii) 
we entered into a consortium with the consultancy firm Latin Consult to provide consultancy services in 
certain cities in Panama and Honduras for the rational use of water and the adoption of a new commercial 
and operational management model; (iii) the production, supply and commercialization of reused water 
and (iv) the implementation and operation of a station for the preconditioning of non-domestic 
wastewater, sludge conditioning and other related activities. 

Other partnership led to the creation of the following companies: Sesamm – Serviços de Saneamento 

de Mogi Mirim S.A., Águas de Andradina S.A., Saneáqua Mairinque S.A., Aquapolo Ambiental, S.A. 
Águas de Castilho S.A. e Attend Ambiental S.A. Although we do not necessarily hold a majority capital 
participation in these companies, shareholder agreements provide us with veto powers or qualified votes 
on certain matters those business associates may come across.  

Corporate Organization 

In  2005,  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  our  board  of  directors, 
after an initial proposal made by the Chief Executive Officer, in accordance with our bylaws. The Chief 
Executive  Officer  is  responsible  for  coordinating  all  management  divisions  in  accordance  with  the 
policies and directives established by our board of directors and board of executive officers, including the 
coordination, evaluation and control of all functions related to Chief Executive Officer’s office and staff, 
integrated  planning,  business  management  and  organization,  corporate  communication,  audit, 
ombudsman, and regulatory matters.  The Chief Executive Officer represents our Company before third 
parties and some of its representation powers can be granted to attorneys-in-fact.  The executive officers 
described below report to the Chief Executive Officer:

financial  and  operational  performance  of  its  division.   These  Chief  Operating  Officers 
are  also  responsible  for  sanitation  advisory  services  to  autonomous  municipalities  and 
for the mediation and the negotiation with communities and local governments, aimed at 
aligning our interests with the interests of our clients.    

Capital Expenditure Program 

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

From 2009 through 2011, our capital expenditure program totaled R$ 6.4 billion, primarily to build 
up  our  infrastructure  and  for  our  efforts  to  reduce  water  losses.   We  have  budgeted  investments  in  the 
amount of R$7.9 billion from 2012 through 2015.  We invested R$1.8 billion, R$2.2 billion and R$2.4 
billion in 2009, 2010 and 2011, respectively.   

The following table sets forth our planned capital expenditures for water and sewage infrastructure 

for the years indicated.

Our  capital  expenditure  program  from  2012  through  2015  will  continue  to  focus  on  achieving  our 
targets by making regular investments in and expanding our infrastructure as well as making investments 
in the reduction of water losses throughout the 363 municipalities we served as of December 31, 2011. 

Main Projects of Our Capital Expenditure Program 

The following is a description of the main projects in our capital expenditure program. 

Metropolitan System Investment 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 capacity of our water systems.  As a result, prior to September 1998, 

29 

 
   
   
   
   
   
part of our customers in this region received water only on alternate days of the week.  We refer to this as 
“rotation.”   In  order  to  remedy  this  situation,  we  implemented  the  Metropolitan  Water  Program 
(Programa Metropolitano de Água) to improve regular water supply to the entire São Paulo metropolitan 
region.   This program  terminated  in  2000  and  the rotation  was  eliminated,  but  we  have  maintained  our 
investment  projections  for  the  region.   During  the  second  phase  of  the  Metropolitan  Water  Program 
between  2006  and  2014,  we  plan  to  expand  the  infrastructure  of  water  storage  tanks  by  210,000  cubic 
meters  and  to  construct  44  water  pumping  stations  and  240 kilometers  of  mains.   The  investment  is 
expected to reach R$2.7 billion and the construction is expected to expand the water production capacity 
by 13.2 cubic meters per second until 2014.  We have been working on this project since 2006, and we 
expect to complete it by 2014.  In 2011, we invested approximately R$102.5 million, respectively, in this 
project.     

The  metropolitan  region  suffers  from  a  water  shortage,  which  requires  us  to  obtain  water  from 
increasingly distant sources.  In order to remedy this situation, we are currently developing a new supply 
system called São Lourenço that should be able to benefit a population of almost 1.5 million people.  We 
have  already  concluded  the  project’s  conceptual  studies  and  are  currently  developing  its  infrastructural 
projects.  We may propose a Public Private Partnership to the government of São Paulo. 

In June 2008, we entered into a Public Private Partnership (Parceria Público-Privada), or PPP, with 
Cab  Spat,  a  special  purpose  company  whose  main  shareholders  are  Cab  Ambiental  and  Galvão 
Engenharia  S.A.   Cab  Spat  will  be  responsible  for  (i)  expanding  the  Taiaçupeba  water  treatment  plant 
capacity from ten cubic meters per second to 15 cubic meters per second, (ii) building 17.7 kilometers of 
water connections and mains, (iii) building four water storage tanks with total capacity of 70,000 cubic 
meters, (iv) installing boosters, and (v) building pumping stations.  The total investment in projects to be 
undertaken by Cab Spat during the first two years of the PPP is estimated at R$320.0 million.  Cab Spat 
will also perform maintenance on the dams of the Alto Tietê System, in connection with which Cab Spat 
will  also  provide  civil  engineering,  electromechanical  and  operational  services,  as  well  as  sludge 
treatment and the corresponding services regarding water adduction and water supply.  The total value of 
the  project  is  estimated  at  R$1.0 billion.   We  intend  to  pay  these  investments  over  15  years  upon  the 
completion of the contracted projects and services.  In December 2011, the services were concluded and 
the system’s nominal capacity was increased from 10 to 15 cubic meters per second, directly benefiting 
1.5 million people in the east region of the São Paulo metropolitan region, in addition to improving the 
reliability, flexibility and availability of the integrated water system that services the state’s metropolitan 
region.  The increase in production will improve the east, north and west regions water supply levels since 
it  will  be  possible  to  transfer  water  from  the  east  system  to  other  localities.   In  2011,  we  invested 
approximately R$ 121.4 million in this project.   

Tietê Project 

The Tietê river crosses the São Paulo metropolitan region and receives most of the region’s run-off 
and  wastewater.   The  environmental  status  of  the  river  reached  a  critical  level  in  1992.   In  an  effort  to 
reverse the situation, the State of São Paulo created a recovery program designed to reduce pollution of 
the Tietê river by installing sewage collection lines along the banks of the Tietê river and its tributaries.  
These lines collect raw sewage and deliver it to our sewage treatment facilities.  We completed the first 
phase of the program between 1992 and 1998. 

In connection with the first phase of the Tietê Project (Projeto Tietê), in June 1998, we completed the 
construction  of  three  additional  sewage  treatment  facilities  and  invested  a  total  of  US$1.1  billion,  of 
which  US$450.0  million  was  financed  by  the  Inter-American  Development  Bank,  or  IADB, 
approximately  US$100  million  by  the  Caixa  Econômica  Federal,  or  the  Caixa,  and  approximately 
US$550 million by us.   

The  second  phase  of  the  project  was  carried  out  from  2000  through  2008,  with  investments  of 
approximately US$500 million, of which US$200.0 million were financed by the IADB, R$60.0 million 
by the BNDES, and R$180.0 million by the BNDES through another financial institution.  In this phase, 
290,000  sewage  connections  and  more  than  1,500 kilometers  of  sewage  collections  networks,  branch 
collectors and interceptors were installed and/or built.   

The  main  objective  of  this  second  phase  was  to  continue  expanding  and  optimizing  the  sewage 
systems of the São Paulo metropolitan region, primarily focusing on actions that allow for the delivery of 
a higher volume of raw sewage to the sewage treatment facilities that were built in the first phase of the 

30 

 
Tietê Project.  Upon the conclusion of the second phase of the project in 2008, we were able to collect 
approximately  5,000  liters  of  raw  sewage  per  second  and  send  it  for  treatment  in  the  five  sewage 
treatment  plants  of  our  integrated  system.   As  part  of  the  second  phase  of  the  Tietê  Project,  we 
implemented a 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.  

The first and second phases of the Tietê Project contributed to an increase from 70.0% to 84.0% in 
the sewage collection rate and an increase from 24.0% to 70.0% in the treatment of the sewage collected 
in  the  São  Paulo  metropolitan  region.   As  a  result,  the  sewage  collection  system  benefited  15.8 million 
people (5.1 million more than the number of people served when the Tietê Project was initiated), and the 
sewage treatment benefited 11.1 million people (8.5 million more than the number of people served when 
the Tietê Project was initiated).  

As of December 31, 2011, we owed US$386.9 million to the IADB for the financing it provided.  For 
further  information  on  the  agreement  entered  into  with  the  IADB,  see  “Item 5.B.  Liquidity  and  Capital 
Resources—Capital  Sources.”   We  currently  provide  secondary  treatment  to  approximately 68%  of  the 
sewage collected in the São Paulo metropolitan region.  The five principal sewage treatment facilities in 
the São Paulo metropolitan region have an aggregate installed capacity of 18 cubic meters of sewage per 
second  and  currently  treat  an  aggregate  of  15.6  cubic  meters  of  sewage  per  second.   We  plan  to  build 
additional collection lines to direct more raw sewage to our treatment facilities.    

The third phase of the Tietê Project, designated as “the decontamination of the Tietê river,” aims at 
contributing to the recuperation of the water quality of the Tietê river basin through the expansion of the 
level of collection to 87.0% and treatment of sewage to 84.0% in the São Paulo metropolitan region.  The 
total estimated cost of the third phase is approximately US$1.1 billion, of which US$600.0 million will be 
financed pursuant to the IADB Loan entered into on September 3, 2010.  The program plan of the third 
phase comprises mainly (i) drainage collection (collection networks and home connections), (ii) removal 
and transport of the drainage for treatment (branch collectors and interceptors), and (iii) the construction 
of  sewage  treatment  plants,  not  only  of  the  integrated  drainage  system  of  the  São  Paulo  metropolitan 
region,  but  also  of  various  isolated  systems  in  the  same  region,  during  a  six-year  period  from  2010  to 
2016.  Approximately 43% of the work is already under execution and 25% is undergoing public bidding 
processes.   After  the  third  phase  of  the  Tietê  Project,  the  sewage  collection  system  will  benefit  an 
additional 1.5 million people and the sewage treatment will benefit an additional 3.0 million  people.  

We  are  currently  planning  the  fourth  and  final  phase of  the  Tietê  Project,  which  should  take  place 
between  2013  and  2018.  The  main  objective  of  the  fourth  phase  if  to  completely  end  the  dumping  of 
untreated sewage into the Tietê river in the area in which we are the water services provider.    

Corporate Program for Water Loss Reduction   

The  objective  of  the  Corporate  Program  for  Water  Loss  Reduction  (Programa  Corporativo  de 
Redução  de  Perdas)  is  to  decrease  water  losses  more  efficiently  by  means  of  the  integration  and 
expansion  of  the  existing  initiatives  in  our  business  units.   We  began  structuring  the  program  in  the 
second half of 2007 and finalized it in 2008.  We have invested R$1.0 billion in this project so far and 
anticipate investments of approximately R$4.3 billion throughout the program’s 11-year term, beginning 
in 2009.  Funding will come from our own resources as well as from loan agreements entered with the 
Japan International Cooperation Agency (JICA), with Caixa Econômica Federal and with BNDES. The 
program aims to reduce the incidence of water loss from 436 liters per connection per day in December 
2008  to  211  liters  per  connection  per  day  in  2019,  which  is  equivalent  to  reducing  water  losses  from 
27.8% in December 2008 to 15.0% in 2019. This goal will be revised based on the results reached so far 
and the expected reduction with the implementation of the Corporate Program for Water Loss Reduction 
in the 2012-2019 period. 

In  2011,  we  invested  approximately  R$326.7  million  in  this  program.   As  of  December  31,  2011, 

water losses were reduced to 25.6% from 26% in 2010.

New Life Program 

The  New  Life  Program  (Programa  Vida  Nova)  includes  projects  focused  on  the  improvement  and 
preservation  of  water  reserves  in  the  São  Paulo  metropolitan  region  and  the  urban  development  of  the 
region, especially in the Guarapiranga and Billings mains.  The resources will be mostly invested in the 
creation  of  infrastructure  to  collect  sewage  in  the  region,  and  to  direct  it  to  treatment  plants,  while 
avoiding  its  pouring  directly  into  the  springs.   The  program  also  includes  protection  activities  of  green 
areas and the urbanization of favelas   (shantytowns) and is expected to directly benefit 50,000 families. 

The  State  government,  local  authorities  and  the  federal  government  will  invest  approximately 
R$1.3 billion in the program.  We will fund this program with R$355.0 million.  The State Secretariat for 
Sanitation  and  Water  Resources  coordinates  the  program  with  our  involvement  and  that  of  the  Urban 
Development  Company  of  São  Paulo  (Companhia  de  Desenvolvimento  Habitacional  e  Urbano),  or  the 
CDHU, and local governments in the region. 

As of December 31, 2011, R$45.5 million have been invested in this program by us, of which R$29.4 

million were invested in 2011.  

Clean Stream Program  

The Clean Stream Program (Programa Córrego Limpo) is a partnership between the State, through 
us, and the municipality of São Paulo, and aims to clean and decontaminate urban streams in the city of 
São  Paulo,  by  improving  the  sewage  sanitary  system,  the  elimination  of  sewage  through  streams  and 
rainwater galleries, the cleaning of streams and stream borders, as well as the removal and relocation of 
properties  located  in  riverbanks.   As  of  December 31,  2011,  approximately  R$129.5  million  had  been 
invested in this program and 103 urban streams had been decontaminated, benefiting approximately 1.7 
million people. 

                In 2012, we expect to decontaminate 45 additional urban streams, benefiting over 700 thousand 
people. The estimated capital expenditures for this program in 2012 is R$36 million.   

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 
invested R$1,091.0 million, R$943.7 million and R$1,109.2 millions, in these projects in 2009, 2010 and 
2011,  respectively,  and  we  have  budgeted  for  additional  capital  expenditures  of  approximately  R$  2.2 
billion from 2012 through 2015.   

Clean Wave Program 

The main goals of the Clean Wave Program (Programa Onda Limpa) are to improve and expand the 
sewage systems in the municipalities comprising the Baixada Santista metropolitan region, increasing the 
sewage  collection  rate  to  95.0%,  and  treating  100.0%  of  the  collected  sewage  and  thereby  improving 
bathing water quality at 82 beaches in the region by 2013.  On August 6, 2004, we entered into a credit 
agreement with the JBIC for the financing of this project, which is guaranteed by the Federative Republic 
of  Brazil,  for  a  total  amount  of  R$382.8  million.   On  October 1,  2008,  the  JICA  incorporated  the  loan 
transactions  of  the  JBIC.   For  further  information  on  the  agreement  entered  into  with  the  JICA,  see 
“Item 5.B.  Liquidity  and  Capital  Resources—Capital  Sources.”   As  of  December 31,  2011,  we  had 
invested  approximately  R$1.6  billion in  this  program,  R$  159.8  million of  which  during  the  year 
2011 . With the completion of construction of sewage treatment plants and installation of networks, we 
have prioritized the connection of costumers to the sewage collection system.  Until the end of 2011, we 
had finished 63,000 connections of the total 123,000 expected. 

Northern Coast Clean Wave Program  

The  Northern  Coast  Clean  Wave  Program  (Programa  Onda  Limpa  Litoral  Norte)  will  expand  the 
collection and treatment of sewage in the Northern coast of the State of São Paulo, intending to benefit 
600 thousand people, including the local population  as well as tourists that each year visit the region.  By 
2015, the program will increase the collection and treatment of sewage rate in the region from 36.0% to 
85.0%,  seeking  to  improve  the  health  and  well-being  of  the  population,  in  addition  to  stimulating 
economic development through the increase in tourism in the region. 

32 

 
In 2011, we continued working on two sewage treatment plants in the city of São Sebastião and other 
sewage system projects in the cities of Ubatuba, Ilhabela and São Sebastião, which we expect to complete 
in  2013.   Until  2011,  R$114.6  million  had  already  been  invested  in  this  program,  of  which  R$  24,6 
million were invested in 2011.  

Coastal Water Program 

 The  Coastal  Water  Program  (Programa  Água  no  Litoral)  is  the  main  combination  of  long-term 
activities to expand water production capacity in the Baixada Santista metropolitan region and Southern 
Coast of the State of São Paulo.  Almost three million people, including local population and tourists, are 
expected to benefit from this program.  This program will enable us to increase the level of reliability of 
the  systems,  eliminating  existing  and  potential  deficiencies  and  irregularities  in  the  water  supply.   It  is 
also expected to permit us to expand our services to reach universal coverage in these regions, increase 
the  availability  of  treated  water  and  improve  the  quality  of  water  available  to  the  population.   As  of 
December  31,  2011,  R$472.7  million  has  been  invested  on  this  program  and  we  expect  to  invest 
R$1.1 billion in  the  program  by  2013.   The  Mambu/Branco  Water  Production  System  is  part  of  this 
program.  It will increase water production to supply municipalities in the south of the Baixada Santista, 
increasing  production  from  actual  0.6 cubic  meter  per  second  to  1.6  cubic  meters  per  second.  
Additionally,  the  planned  water  treatment  stations  of  Jurubatuba,  Itú  and  Cubatão  are  also  part  of  this 
program.  

New Policies and Programs 

Nossa Guarapiranga 

In December 2011, we launched the Nossa Guarapiranga project, whose main objective is to recover 

water quality of the Guarapiranga basin, a water source for the São Paulo metropolitan region. We 
installed 11 drains to collect residue from rivers in the Guarapiranga basin.  We plan to collect an average 
of 20 cubic meters of residue per day. 

Pró-Conexão  

In December 2011, the municipality of São Paulo approved a project to offer residences of low-
income families subsidized connections to the sewage system.  The project involves capital expenditure 
amounts of up to R$349.5 million, 80% of which would be sustained by the government of the State of 
São Paulo, while 20% would be paid by us. We believe that this program will increase the efficiency of 
our sewage collection programs and help improve water quality of the region’s rivers and basins, on top 
of improving the quality of life of low-income families.  

We expect that the program will create 192 new thousand connections over the next 8 years and 

affect approximately 800 thousand people. 

Water is Life 

In November 2011, we created the program Water is Life which aims to provide sewage services to 
41  low-income  communities  of  non-urbanized  areas  of  20  municipalities  in  the  regions  of   Alto 
Paranapanema  and  Vale  do  Ribeira.   After  installing  the  required  infrastructure,  an  estimated  capital 
expenditure of R$6 million, we will be responsible for maintaining and operating the sewage systems to 
reach approximately 13 thousand people. 

B.    Business Overview 

Our Operations 

As of December 31, 2011, we provided water and sewage services to 363 municipalities in the State 
of  São  Paulo  either  under  concession  agreements,  program  agreements,  under  another  form  of  legal 
arrangement  or  under  no  formal  agreement.   We  also  supply  treated  water  on  a  wholesale  basis  to  six 
municipalities located in the São Paulo metropolitan region and to the municipality of Sumaré.  Pursuant 
to  article  2  of  our  bylaws,  our  corporate  purpose  includes  the  provision  of  water  supply  and  sewage 
services,  urban  rain  water  management  and  drainage  services,  urban  cleaning  services  and  solid  waste 

33 

 
management services.  In addition, our bylaws authorize us to carry out other related activities, including 
the planning, operation and maintenance of production systems, the storage, preservation and trading of 
energy,  and  the  trading of  services, products,  benefits  and  rights  that,  directly  or  indirectly,  result  from 
our assets, projects and activities, and the right to operate a subsidiary anywhere in Brazil or abroad to 
provide the services mentioned above.   

Because of the enactment of the Basic Sanitation Law, which regulates the basic sanitation industry 
in  Brazil,  we  currently  operate  under  two  different  contractual  environments:   (i)  for  the  concession 
agreements that have already expired, we are currently renegotiating or will negotiate a new agreement 
that follows the terms and conditions of the Basic Sanitation Law, or program agreements; and (ii) for the 
concession agreements that have not expired, we will continue to operate under the terms and conditions 
of  the  previous  concession  agreements,  except  in  circumstances  where  the  Basic  Sanitation  Law  is 
applicable even when the concession agreement is still valid.  For further information on this topic, see 
“Government  Regulation—Concessions—Public  Consortia  and  Cooperation  Agreement  Law  for  Joint 
Management.”  

The  Basic  Sanitation  Law  required  water  and  sewage  service  providers,  such  as  us,  to  execute  a 
formal agreement by December 31, 2010 with every municipality to which they provide services without 
a valid legal and binding instrument.  If we failed to enter into such formal agreements by December 31, 
2010, the concessions would no longer be valid.  As of December 31, 2011, 99 of our concessions were 
still  in  the  process  of  regularization  through  the  execution  of  formal  agreements.   See  “3.D.  Risks 
Factors—Risks Relating to Our Business—We cannot anticipate the effects that further developments of 
the Basic Sanitation Law and its interpretation will have on the basic sanitation industry in Brazil and on 
us”  and  “3.D.  Risks  Factors—Risks  Relating  to  Our  Business—We  have  not  entered  into  formal 
agreements  for  the  provision  of  water  and  sewage  services  with  certain  of  the  municipalities  we  serve, 
including municipalities in metropolitan regions, as required by the Basic Sanitation Law, and therefore 
we may not be able to enforce our rights to continue to provide services in these municipalities.” 

Concessions  

Pursuant to the Brazilian Constitution, the authority to develop public water and sewage systems is 
shared  by  the  states  and  municipalities,  with  the  municipalities  having  primary  responsibility  for 
providing  water  and  sewage  services  to  their  residents.   The  Constitution  of  the  State  of  São  Paulo 
provides that the State shall assure the correct operation, necessary expansion and efficient administration 
of water and sewage services in the State of São Paulo by a company under its control. 

According to the Basic Sanitation Law, existing concessions will remain in effect until payment of 
indemnification is made based on the valuation of investments.  The Basic Sanitation Law provides that 
our new concession agreements be planned, supervised and regulated by the municipalities together with 
the  State  under  a  new  model  of  associated  management  that  will  allow  for  better  control,  supervision, 
transparency and efficiency in the provision of public services.

363 
municipalities. Substantially  all  of  these  concessions  have  30-year  terms.   Due  to  court  orders,  we 
temporarily  suspended  our  services  in  five  other  municipalities  (Araçoiaba  da  Serra,  Cajobi,  Iperó, 
Álvares Florence and Macatuba), that as of December 31, 2011 accounted for less than 0.1% of our gross 
revenues. In January 2011, we resumed the provision of our services to the municipality of Tarumã that 
had  been  previously  suspended  by  a  court  order.   For  more  information,  see  “Item 8.A.  Financial 
Information—Consolidated  Statements  and  Other  Financial 
Information—Legal  Proceedings—
Concession-Related Legal Proceedings.”  Between January 1, 2007 and December 31, 2011, we entered 
into  contracts  with  225  municipalities  (including  our  services  agreement  with  the  city  of  São  Paulo)  in 
accordance  with  the  Basic  Sanitation  Law,  of  which  25,  were  entered  into  in  2011.   In  addition  to  the 
contracts that have 30-year terms, the municipalities entered into cooperation contracts with the State of 
São Paulo, delegating the regulation and monitoring of the provision of services to the ARSESP.  As of 
December  31,  2011,  99  of  our  concessions  had  expired  and  we  have  been  in  negotiation  with  these 
municipalities  to  execute  program  agreements  to  substitute  the  expired  concessions.   From  January  1, 
2012 through 2033, 39 concessions will expire.  Despite these 99 concessions having expired in 2011, we 
are  renegotiating  them  and  we  were  continuing  to  provide  water  and  sewage  services  to  all  99 
municipalities as of December 31, 2011.  We have entered into an agreement with the State and city of 
São  Paulo  for  the  provision  of  water  and  sewage  services  in  the  city  of  São  Paulo  for  a  30-year  term 
expiring  in  June  2040,  which  in  the  year  ended  December 31,  2011  accounted  for  51.4%  of  our  gross 

34 

 
revenues  from  sales  and  services  (including  revenues  relating  to  the  construction  of  concession 
infrastructure).   

In  February 2006,  we  created  a  new  division  to  manage  the  renewal  of  expiring  concessions.   The 
main responsibility of this division, which reported directly to the Chief Executive Officer, was to renew 
and thus maintain the existing base of municipalities  that  we operate and formalize contracts under the 
new  model  of  associated  management.   Following  the  increase  in  the  demand  for  regulatory  work,  this 
division  shifted  its  focus  to  regulatory  matters  and  its  main  roles  currently  involve  centralizing 
communication  with  the  regulatory  agencies,  driving  business  to  the  new  regulatory  regime  and 
proposing matters in which we have an interest to the ARSESP. 

In  April 2011,  we  created  a  specific  area  in  our  Financial  Economic  and  Investor  Relations  Office 
responsible for costs and tariffs, given the subject’s importance to the continuation of our business.  We 
also  created  a  statutory  Regulatory  Affairs  Committee.   The  committee  is  composed  of  our  Chief 
Executive Officer, our Chief Financial and Investor Relations Officer, our Metropolitan Officer and our 
Regional  System  Officer  and  is  responsible  for  defining  the  guidelines,  strategies  and  regulatory 
recommendations for our Company and coordinating the work of the Regulatory Affairs Department.  

The  current  concessions  are  based  on  a  standard  form  of  agreement  between  us  and  the  relevant 
municipality.  Each agreement received the prior approval of the legislative council of each municipality.  
The  assets  comprising  the  existing  municipal  water  and  sewage  systems  are  transferred  from  the 
municipality to us in order for us to provide the contracted services.  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 
12%  certain  discount  factor  to  us,  from  the  concession  being  acquired.   For  reference  purposes,  the 
discount rate adopted in concession contracts was set by the ARSESP in 2011 at 8.6%.  

The main provisions of the existing concession agreements are as follows: 

(cid:131)  we assume all responsibility for providing water and sewage services in the municipality;    

(cid:131)  according to the municipal laws authorizing the concession, we could collect tariffs for our services 

without prior authorization of the municipality.  Tariff readjustments follow the guidelines 
established by the Basic Sanitation Law and the ARSESP;    

(cid:131)  as a general rule, to date, we are exempt from municipal taxes, and no royalty is payable to the 

municipality with respect to the concession;   

(cid:131)  we are granted rights of way on municipal property for the installation of water pipes and mains, 

and sewage lines; and    

(cid:131)  upon termination of the concession, 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 value of the assets, considered intangible since January 2008, relating to 
the concession.  See Note 2.12 to our financial statements.

Under  the  concession  agreements executed prior  to 1998,  the  reimbursement  for  the  assets  may  be 

through payment of either: 

(cid:131)  the book value of the assets; or  

(cid:131)  the market value of the assets as determined by a third-party appraiser in accordance with the terms 

of the specific agreement.

Since  1998,  contracts  that  we  have  entered  into  with  municipalities  for  the  provision  of  sanitation 
services have been regulated by the Federal Concessions Law No. 8,987/1995.  Generally, these contracts 
have  a  30-year  term,  and  the  total  value  of  the  concession  is  set  by  the  discounted  cash  flow 
method. Under  this  method,  when  the  expected  contractual  cash  flow  is  reached,  the  total  value  of  the 
concession and assets is 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 term, thereby interrupting the normal contractual 
cash  flow,  we  are  paid  an  amount  equal  to  the  present  value  of  the  expected  cash  flow  over  the  years 
remaining in the concession, adjusted for inflation. 

Federal  Law  No.  11,107,  or  the  Federal  Public  Consortia  and  Cooperation  Agreement  Law, 
established  the  legal  basis  for  the  administration  of  public  service  contracts,  giving  municipalities 
responsible for sanitation services greater rights and obligations and setting out more clearly the provision 
of services and the responsibilities of the parties.  New agreements entered into following the expiry of 
concession  agreements  under  the  previous  law  will  follow  this  new  model.   See  “—Government 
Regulation—Concessions—Public Consortia and Cooperation Agreement Law for Joint Management.” 

Our new agreement model follows the provisions of the Basic Sanitation Law.  The main contractual 
provisions,  among  others,  are  joint  execution  of  responsibilities  related  to  planning,  supervision  and 
regulation  of  services  and  appointment  of  regulatory  authority  of  services  and  periodic  disclosure  of 
accounts. 

Furthermore,  the  economic  and  financial  formulas  in  new  agreements  must  be  based  on  the 
discounted  cash  flow  methodology  and  on  the  revaluation  of  returnable  assets.   Pursuant  to  the  Basic 
Sanitation  Law,  our  own  preexisting  assets  will  be  returnable  assets,  but  we  will  carry  out  all  new 
investments  and  the  municipalities  will  record  them  as  assets.   The  municipalities  will  then  transfer 
possession  of  these  assets  to  us  for  our  use  and  management  and  will  also  record  a  credit  in  the  same 
amount of the assets recorded in our favor.  According to Article 42 of the Basic Sanitation Law and the 
new agreement model, investments made during the contractual period are the property of the applicable 
municipality, which in turn generates receivables for us that are to be recovered through the operation of 
the services.  These receivables may also be used as guarantees in funding operations.  

Another  important  development  was  that  the  new  agreement  model  includes  exemptions  from 
municipal taxes applicable on our operational areas and the possibility of the revaluation of our assets that 
existed  prior  to  the  execution  of  the  program  agreements  in  cases  involving  the  early  resumption  of 
services by the concession authority. 

Municipalities  have  the  inherent  power  under  Brazilian  law  to  terminate  concessions  prior  to  their 
contractual expiration dates for reasons of public interest.  The municipalities of Diadema and Mauá, two 
municipalities  we  previously  served,  terminated  our concessions  in  February 1995  and  December 1995, 
respectively.  The municipality of Mauá terminated our concession with our consent.  The municipality of 
Diadema  had  terminated  our  concession  without  our  consent  after  asserting  that  we  did  not  provide 
adequate water and sewage services.  In 2011, the municipality of Diadema agreed with us to develop a 
share  infrastructure  for  the  provision  of  water  and  sewage  services  through  a  mixed-capital  company 
called Companhia de Água e Esgoto de Diadema, or CAED.  We are not yet able to predict when CAED 
will begin operations. Despite these developments, we currently serve the municipalities of Diadema and 
Mauá  through  the  supply  of  water  on  a  wholesale  basis.   The  indemnities  receivables  related  to  the 
municipality of Mauá totaled R$ 85.9 million are not being recognized in the financial statements due to 
the  uncertainties  in  the  collection.   For  further  information  on  the  lawsuits  that  arose  out  of  these 
developments,  see  “Item 8.A.  Financial  Information—Consolidated  Statements  and  Other  Financial 
Information—Legal Proceedings.” 

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.   However,  we  cannot  be  certain  that  other  municipalities  will  not  seek  to  terminate  their 
concessions in the future.  See “Item 3.D. Risk Factors—Risks Relating to Our Business—Municipalities 
may,  under  certain  circumstances,  terminate  our  concessions  before  their  expiration  and  the 
indemnification may be inadequate to recover the full value of our investments.” 

In  addition,  there  is  currently  ongoing  litigation  with  respect  to  municipalities  that  intend  to 
expropriate our water and sewage systems, or to terminate concession agreements before paying us any 

36 

 
indemnification.  For a detailed discussion on these proceedings, see “Item 8.A. Financial Information—
Consolidated  Statements  and  Other  Financial  Information—Legal  Proceedings—Concession-Related 
Legal Proceedings.” 

Operations in the City of São Paulo and Certain Metropolitan Regions 

As  of  December  31,  2011,  99  concessions  had  expired  which  jointly  accounted  for  23.8%  of  our 
gross revenues.  We entered into 25 agreements in the year ended December 31, 2011, bringing the total 
number of program agreements entered into between 2007 and 2011 to 225.  These 25 new agreements 
accounted for 2.9% of our total revenues and 3.3% of our intangible assets as of December 31, 2011.   

The  Basic  Sanitation  Law  provides  that,  in  case  of  termination  of  the  relationship  with  the 
aforementioned  municipalities,  the  municipalities  should  pay  us  an  indemnity,  in  an  amount  to  be 
appraised, notwithstanding the non-existence of a concession agreement.  

On  June  23,  2010,  the  State  and  the  city  of  São  Paulo  entered  into  a  convention  with  the 
intermediation and consent of our Company and of the ARSESP pursuant to which they agreed to jointly 
manage  the  planning  of  and  investment  in  the  basic  sanitation  system  of  the  city  of  São  Paulo,  among 
other  things.   This  agreement  established  that  the  State  and  the  city  of  São  Paulo  would  enter  into  an 
agreement with us, granting us exclusive rights in the provision of water and sewage services in the city 
of São Paulo.  In addition, the agreement established the role of the ARSESP in regulating and overseeing 
our activities and established a management committee that will be responsible for planning the water and 
sewage services and for reviewing our investment plans.  The management committee will be composed 
of six members appointed for two year terms.  The State and the city of São Paulo will have the right to 
appoint  three  members  each.   We  are  permitted  to  participate  in  the  meetings  of  the  management 
committee; however, we are not afforded any voting rights.   

On  June  23,  2010,  we  entered  into  a  formal  agreement  with  the State  and  the  city  of São Paulo  to 
regulate the provision of water and sewage services in the city of São Paulo for a 30-year period, which 
may be extended for an additional 30-year period.  The Municipal Law No. 14,934/2009 authorized the 
city of São Paulo to enter into an agreement with us.  The agreement establishes, among other things, how 
specific amounts of gross revenues from the services we render should be allocated (after deduction of 
COFINS and PASEP).  This agreement requires, among other things, (i) to invest at least 13.0% of the 
gross  revenues  from  sales  and  services  we  obtain  from  the  municipality  of  São  Paulo,  net  of  taxes  on 
revenues  in  the  improvement  of  water  and  sewage  infrastructure  in  the  city  of  São  Paulo;  (ii)  that  our 
investment plan must be compatible with the activities and programs included in the sanitation plan of the 
State, the sanitation plan of the city of São Paulo and, if necessary, the sanitation plan of the metropolitan 
region  of  São  Paulo;  and  (iii)  that  we  contribute  7.5%  of  the  gross  revenues  we  obtain  from  this 
agreement to the São Paulo Municipal Sanitation Fund. The investment plan under this agreement is not 
irrevocable and will be reviewed by our management committee every four years, especially with regards 
to  investments  to  be  executed  in  the  subsequent  period.  In  addition,  the  agreement  provides  that  the 
ARSESP  will  ensure  that  the  tariffs  charged  (a)  will  adequately  compensate  us  for  the  services  we 
provide  and  (b) can  be  adjusted  to  restore  the  original  balance  between  each  party’s  obligation  and 
economic gain (equilíbrio econômico-financeiro).  Finally, the agreement envisages the remuneration of 
the  net  assets  in  operation,  calculated  preferably  through  asset  valuation  or  by  the  monetarily  updated 
book  value,  to  be  established  by  the  ARSESP.   The  agreement  also  foresees  the  remuneration  of  the 
investments to be made by us, such that there will be no residual value at the end of the contract period. 
 We  currently  have  an  investment  plan  in  place  that  consider  these  obligations  and  also  addresses  the 
compatibility  with  the  activities  and  programs  included  in  the  sanitation  plan  of  the  State  and  of  the 
municipality of São Paulo and, if necessary, the plan of the metropolitan region of São Paulo.    

Wholesale Operations 

Water Services on a Wholesale Basis  

We  provide  water  services  on  a  wholesale  basis  to  six  municipalities  located  in  the  São  Paulo 
metropolitan region (Diadema, Mauá, Santo André, São Caetano do Sul, Guarulhos and Mogi das Cruzes) 
and to the municipality of Sumaré.  The agreements to provide water services on a wholesale basis must 
comply  with  the  Basic  Sanitation  Law,  which  regulates  the  stages  of  the  provision  of  each  service, 
designating them as interdependent activities whose provision requires the supervision of an independent 
agency, a specific registration for the activities’ cost and assurance of payment among the several service 

37 

 
providers in order to continue the provision of the services, in accordance with the rules to be published 
by the ARSESP.  Our agreements currently comply with the provisions of the Basic Sanitation Law.  In 
2011, the revenues from these services were R$203.5 million. 

We are currently negotiating with the city of Diadema so as to liquidate the outstanding debts owed 
by  Diadema  and  Saned  to  us.   For  further  information  on  this  outstanding  debt,  see  Note  9  to  our 
consolidated financial statements included elsewhere in this annual report.  

Sewage Services on a Wholesale Basis  

We  provide  sewage  services  on  a  wholesale  basis  to  the  municipalities  of  Mogi  das  Cruzes,  Santo 
André, São Caetano, Mauá and Diadema.  The negotiation of the agreement for the provision of sewage 
services  on  a  wholesale  basis  with  the  municipality  of  Santo  André  had  the  intervention  of  the  Public 
Prosecution  Office,  and  in  other  municipalities  the  negotiation  of  the  agreements  was  a  result  of  our 
efforts  concerning  the  environment  and  the  awareness  of  the  municipal  public  authorities  regarding  to 
environmental issues. Through these agreements, in 2011 we treated about 27.2 million cubic meters of 
sewage from these municipalities. This is an example of our social-environmental responsibility actions 
and our commitment to these actions. In 2011, the revenues from sewage services on a wholesale basis 
were R$21.1 million.  

In December 2008, we entered into a five-year agreement for the collection and treatment of 20.0% 
of  the  sewage  generated  by  the  city  of  Guarulhos.   Due  to  the  complexity  of  the  construction  works 
related to the provision of these services, we have not yet started to provide the sewage services to the 
city of Guarulhos.  

Description of Our Activities 

As set forth in Article 2 of our bylaws, our corporate purpose is to render basic sanitation services 
with the goal of providing basic sanitation services to the entire population in the municipalities where we 
conduct  our  activities  without  harming  our  long-term  financial  sustainability.   Our  activities  comprise 
water  supply,  sanitary  sewage  services,  urban  rainwater  management  and  drainage  services,  urban 
cleaning  services,  solid  waste  management  services  and  related  activities,  including  the  planning, 
operation,  maintenance  and  commercialization  of  energy,  and  the  commercialization  of  services, 
products, benefits and rights that directly or indirectly arise from our assets, operations and activities.  We 
are  allowed  to  act  in  a  subsidiary  form  in  other  Brazilian  locations  and  abroad.   See  “—Government 
Regulation—Concessions—Public Consortia and Cooperation Agreement Law for Joint Management.” 

We set forth below a description of our activities. 

Water Operations 

Our supply of water to our customers generally involves abstraction of water from various sources, 
subsequent treatment and distribution to our customers’ premises.  In 2011, we produced approximately 
2,992.0 million cubic meters of water.  The São Paulo metropolitan region (including the municipalities 
to which we supply water on a wholesale basis) currently is, and has historically been, our core market, 
accounting for approximately 71% of water invoiced by volume in 2011. 

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

indicated.

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

(cid:131)       water discharged for periodic maintenance of water mains and water storage tanks;   

(cid:131)       water supplied for municipal uses such as firefighting; 

(cid:131)       water consumed in our own facilities; and   

(cid:131)       estimated water losses associated with water we supply to favelas (shantytowns).    

Seasonality 

Although seasonality does not affect our results in a significant way, in general, higher water demand 
is observed during the summer and lower water demand during the winter.  The summer coincides with 
the  rainy  season,  while  the  winter  corresponds  to  the  dry  season.   The  demand  in  the  coastal  region  is 
increased by tourism, with the greatest demand occurring during the Brazilian summer holiday months.  

Water Resources 

We can abstract water only to the extent permitted by DAEE pursuant to water usage rights granted 
by it.  Depending on the geographic location of the river basin or if the river crosses more than one state 
(federal domain), the approval of the National Water Agency (Agência Nacional de Águas), or ANA, a 
federal agency under the Ministry of the Environment is 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 the flow from nearby 
rivers, or by a combination of both methods. 

In  order  to  supply  water  to  the  São  Paulo  metropolitan  region,  we  rely  on  20   reservoirs  of  non-
treated water and 192  reservoirs of treated water, which are located in the areas under the influence of the 
eight water producing systems comprising the interconnected water system of the São Paulo metropolitan 
region.   The  capacity  of  the  water  sources  available  for  treatment  in  this  area  is  72  cubic  meters  per 
second.  Total current installed capacity is 72.7  cubic meters per second, which can be treated from the 
interconnected  water  system  of  the  São  Paulo  metropolitan  region. Average  verified  production  during 
2011 on the interconnected water system of the São Paulo metropolitan region was 67.9 cubic meters per 
second.  The Cantareira, Guarapiranga and Alto Tietê systems, as a whole, supplied 84.1% of the water 
we produced for the São Paulo metropolitan region in 2011.  

In 2011, the Cantareira system accounted for 46.4% of the water that we supplied to the São Paulo 
metropolitan  region  (including  the  municipalities  to  which  we  supplied  water  on  a  wholesale  basis), 
which represented 73.9% of our gross revenues from sales and services (excluding revenues relating to 
the construction of concession infrastructure) for the year.  The authorization (outorga) for the Cantareira 
system  to  use  the  water  in  the  Piracicaba  water  basin  was  renewed  on  August 6,  2004,  for  a  ten-year 
period.  

Water basin committees are authorized to charge both for water usage and the dumping sewage into 
water bodies.  Since February 2003, we have been incurring expenses in connection with the use of water 
from  the  Paraíba  do  Sul  river  basin  and,  since  January 2006,  from  the  Piracicaba,  Capivari  and  Jundiaí 
river basins.  At the end of 2010, we started to incur expenses in connection with the use of water from 
the Sorocaba and Médio Tietê river basins   In 2012 we may start to incur expenses in connection with the 
use  of  water  from  the  Alto  Tietê  basin,  where  the  São  Paulo  metropolitan  region  is  located   and  from 
Baixada Santista, Baixo Tietê, Tietê/Jacaré and Tietê/Batalha river basins. The ARSESP has adjusted our 
tariffs  according  to  the  formula  that  we  have  used  since  2003.   According  to  the  formula,  “non-
controllable” costs, such as costs related to water use, are passed on to our customers through our tariffs.  
Although we expect to continue to pass on these expenses to our customers through our tariffs, we are 
uncertain as to whether the river basin committees will change the terms of the charges currently applied 
and whether we will be able to pass on these costs to our customers. For more information on water usage 
regulation, see “—Water Usage.”

We  own  all  of  the  reservoirs  in  our  production  systems  other  than  the  Guarapiranga  and  Billings 
reservoirs  and  a  portion  of  some  of  the  reservoirs  of  the  Alto  Tietê  system,  which  is  owned  by  other 
companies controlled by the State.  We currently do not pay any charges with respect to the use of these 
reservoirs.   In  December 2001,  we  entered  into  an  agreement  with  the  State  whereby  the  State,  among 
other things, agreed to transfer the remaining reservoirs in the Alto Tietê system to us.  We accepted, on a 
temporary basis, the reservoirs in the Alto Tietê System as part of the payment until the State transfers the 
property  rights  with  respect  to  the  reservoirs  to  us.   We  are  unable  to  predict  whether  and  when  these 
reservoirs will be transferred to us because the Public Prosecution Office of the State of São Paulo filed a 
civil  public  action  alleging  that  a  transfer  to  us  of  ownership  of  the  Alto  Tietê  System  reservoirs  is 
illegal.  See “Item 3.D. Risk Factors—Risks Relating to Our Control by the State of São Paulo—We may 
be  required  to acquire  reservoirs  that we use  and that  are owned  by  a State-controlled company,  or we 
may be required to pay substantial charges to the owner with respect to our use of these reservoirs.” 

In  January 2009,  we  began  operating,  monitoring  and  maintaining  the  reservoirs  in  the  Alto  Tietê 
system,  formed  by  the  Ponte  Nova,  Paraitinga,  Biritiba,  Jundiaí  and  Taiaçupeba  reservoirs.   See 
“Item 8.A.  Financial  Information—Consolidated  Statements  and  Other  Financial  Information——Legal 
Proceedings—Other Legal Proceedings.” 

In the cities of the countryside region, our principal source of water consists of surface water from 
nearby rivers and from wells.  The coastal region is provided with water principally by surface water from 
rivers and mountain springs. 

Statewide, we estimate that we are able to supply nearly all of the demand for water in all of the areas 
where  we  operate,  subject  to  droughts  and  extraordinary  climate  events.   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 losses, and the installation of new water connections.  We installed 201,000, 
189,400  and 207,900 new water connections in 2009, 2010 and 2011, respectively.  

The interconnected water system of the São Paulo metropolitan region services 30 municipalities, of 
which  24 are  operated  directly  by  us  under  this  system.   Through  this  system,  we  serve  the  other  six 
municipalities  on  a  wholesale  basis,  and  the  distribution  is  made  by  other  companies  or  departments 
related to each municipality.   

In  order  to  reach  the  final  customer,  the  water  is  stored  and  transported  through  a  complex  and 
interconnected  system.   This  water  system  requires  permanent  operational  supervision,  engineering 
inspection, maintenance, and quality monitoring and measurement control.  

To ensure the continued provision of regular water supply in the São Paulo metropolitan region, we 
intend  to  invest  R$1.3  billion  from  2012  to  2015  to  increase  our  water  production  and  distribution 
capacities as well as to improve the water supply systems.  In 2011, our total investment in water supply 
systems amounted to R$633.2 million.

Water Treatment 

We  treat  all  water  at  our  water  treatment  facilities  prior  to  placing  it  into  our  water  distribution 
network.   We  operate  213  treatment  facilities,  of  which  the  eight  largest,  located  in  the  São  Paulo 
metropolitan  region,  accounts  for  approximately  70%  of  all  water  we  produced  in  2011.   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  water  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.   The 
following  table  sets  forth  the  total  number  of  kilometers  of  water  pipes  and  mains  and  the  number  of 
connections in our network as of the dates indicated.

More  than  90.0%  of  the  water  pipes  in  our  water  distribution  network  are  made  of  cast  iron  or 
polyvinylchloride,  or  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 2011, our water distribution pipes and mains included:  (i) 33,997 kilometers in 

the São Paulo metropolitan region; and (ii) 32,392 kilometers in the Regional systems. 

As  of  December 31,  2011,  we  had  384   storage  tanks  in  the  São  Paulo  metropolitan  region  with  a 
total capacity  of 1.8 million cubic meters, and 1,782 storage tanks in the Regional systems.  As of that 
date, we had 124  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  their  lining  is  replaced.   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 to be adequate 
as of the date of this annual report.  Due to age, external factors such as traffic, the dense population, and 
commercial and industrial development, water pipes and mains in the São Paulo metropolitan region are 
somewhat more susceptible to degradation than those in the Regional systems.  To counter these effects, 
we have a maintenance program in place for water pipes and mains that is intended to address anticipated 
fractures and clogs due to brittleness and encrustation, and to help ensure water quality in the region.  The 
new customers are responsible for covering the part of the costs of connecting to our water distribution 
network that are related to the connecting of customers water pipes that are more than 20 meters away 
from the water mains.  Thereafter, the customer must cover the costs of connecting to the network from 
the  customer’s  premises,  including  costs  of  purchasing  and  installing  the  water  meter  and  related  labor 
costs.   We  perform  the  installation  of  the  water  meter  and  conduct  periodical  inspections  and 
measurements.  After completion of installation, the customer is responsible for the water meter.  

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

Water Losses 

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

Since  2005,  we  have  used  a  method  of  measuring  our  water  losses  based  on  worldwide  market 
practice for the industry.  According to this measurement method, average water losses are calculated by 
dividing (i) average annual water loss by (ii) the average number of active water connections multiplied 
by 366.  The result of this calculation is the number of liters of water lost per connection per day. 

Using this calculation method, as of December 31, 2011, we experienced 469 liters/connections per 
day  of  water  losses  in  the  São  Paulo  metropolitan  region  and  280  liters/connections  per  day  in  the 
Regional systems, averaging 394 liters/connections per day.  We plan to reduce total water losses from 
394 liters/connections per day to 211 liters/connection per day between 2011 and 2019.  Over the same 
period, in terms of percentage, we intend to reduce total water losses from 25.6% to 13.0%, however, this 
goal  will  be  revised  based  on  the  results  reached  so  far  and  the  expected  reduction  with  the 
implementation of the corporate program for water loss reduction in the 2012-2019 period. 

Our strategy to reduce water loss has two approaches: 

(cid:131)  reduction in the level of physical losses, which result mainly from leakage, primarily by replacing 

and repairing water mains and pipes, and installing probing and other equipment, including 
strategically located pressure-regulating valves; and 

(cid:131)  reduction of non-physical losses, which result primarily from the inaccuracy of our water meters 

installed at our customers’ premises and at our water treatment facilities, and from clandestine and 
illegal use, by upgrading  and replacing inaccurate water meters and expanding our anti-fraud 
personnel. 

       We are taking measures to decrease physical losses by reducing response time to fix leakages to less 
than  24 hours  and  by  better  monitoring  non-visible  water  mains  fractures.   Among  other  initiatives,  we 
have adopted the following measures to reduce physical water losses: 

(cid:131)  the introduction of technically advanced valves to regulate water pressure throughout the water 
mains in order to maintain the appropriate water pressure to the downstream consumption needs 
each day.  These valves are programmed to respond automatically to variations in demand.  During 
peak usage, the flow of water in the pipes is at its highest point; however, when demand decreases, 
pressure builds up in the water mains and the resulting stress on the network can cause significant 
water loss through cracks and an increase in ruptures of the pipes.  The technically advanced valves 
are equipped with probes programmed to feed data to the valve in order to reduce or increase 
pressure to the water mains as water usage fluctuates.  As of December 31, 2011, we had installed 
1,783 valves at strategic points in the network, with 1,055 valves being installed in the São Paulo 
metropolitan region and 728 in the Regional systems;    

(cid:131)  the reconfiguration of interconnected water distribution to permit the distribution of water at lower 

pressure;    

(cid:131)  the implementation of routine operational leak detection surveys in high water pressure areas to 

reduce overall water losses; 

42 

 
 
  
  
          
  
  
  
   
(cid:131)  the monitoring of and improved accounting with respect to water connections, especially for large 

volume customers;  

(cid:131)  regular checking on inactive customers and monitoring non-residential customers that are 

accounted for as residential customers and, therefore, billed at a lower rate; 

(cid:131)  preventing fraud with the use of new, more sophisticated water meters that are more accurate and 

less prone to tampering;  

(cid:131)   installing water meters where none are present; and  

(cid:131)  conducting preventive maintenance of existing and newly installed water meters. 

Water Quality 

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

In general, the State of São Paulo has excellent water quality from underground or superficial water 
sources.  However, high rates of population growth, increased urbanization and disorganized occupation 
of  some  areas  of  the  São  Paulo  metropolitan  region  has  reduced  the  quantity  and  quality  of  water 
available  to  serve  the  population  in  the  southern  area  of  the  São  Paulo  metropolitan  region  and  in  the 
coastal region.  Currently, we successfully treat this water to make it potable.  We also work to recover 
the quality of water of mains and invest in improvements of our treatment systems to ensure the quality 
and availability of water for the upcoming years. 

Water  quality  is  monitored  at  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, as required 
by  our  standards  and  those  set  by  statute.   Our  laboratories  analyze  an  average  of  50,000  samples  per 
month on distributed water, with samples collected from residences.  Our central laboratory located in the 
city  of  São  Paulo  is  responsible  for  organic  compound  analysis  using  the  chromatographic  and 
spectrometric  methods,  as  well  as  heavy  metals  analysis  by  atomic  absorption  technique.   All  of  our 
laboratories have obtained the ABNT NBR ISO 9001 certification and our central laboratory and 11 of 
our regional laboratories have obtained the ABNT NBR ISO IEC 17025 accreditation (accreditation for 
general requirements for the competence of testing and calibration laboratories) awarded by the National 
Institute  of  Metrology,  Standardization  and  Industrial  Quality  (Instituto  Nacional  de  Metrologia, 
Normalização e Qualidade Industrial), or the INMETRO.  

All chemical products used for water treatment are analyzed and follow strict specifications set out in 
recommendations made by the National Health Foundation (Fundação Nacional de Saúde), or NHF, the 
Brazilian Association of Technical Rules (Associação Brasileira de Normas Técnicas), or the ABNT, and 
the American Water Works Association, or the AWWA, to eliminate toxic substances that are harmful to 
human health.  From time to time, we face problems with the proliferation of algae, which may cause an 
unpleasant taste and odor in the water.  In order to mitigate this problem, we work on:  (i) fighting algae 
growth at the water source and (ii) using advanced treatment processes at the water treatment facilities, 
which  involve  the  use  of  powdered  activated  carbon  and  oxidation  by  potassium  permanganate.   The 
algae  growth  creates  significant  additional  costs  for  water  treatment  because  of  the  higher  volumes  of 
chemicals used to treat the water.  In 2011, we did not detect significant algae growth. 

We  participate  in  the  New  Life  Program  which  includes  a  Water  Source  Program  (Programa 
Mananciais),  together  with  other  organizations  engaged  in  the  promotion  of  urban  development  and 
social inclusion to mitigate the pollution problem in the São Paulo metropolitan region.  In addition, we 
also participate in the Clean Stream Program to clean up important streams in city of São Paulo.  Other 
initiatives  also  aimed  at  improving  the  water  quality  in  our  water  sources  located  in  the  metropolitan 
region  of  São  Paulo  are  Guarapiranga  and  Pró-Conexão.   See  “—Capital  Expenditure  Program—Main

Projects  of  Our  Capital  Expenditure  Program—Metropolitan  System  Investment  Program—New  Life 
Program and Clean Stream Program.”  

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 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 and removal of sewage through our sewage systems and for its 
subsequent  disposal  with  or  without  prior  treatment.   As  of  December 31,  2011,  we  collected 
approximately 86% of all the sewage produced in the municipalities in which we operate in the São Paulo 
metropolitan region.  In addition, during the year ended December 31, 2011, we collected approximately 
71%  of  all  the  sewage  produced  in  the  municipalities  in  which  we  operate  in  the  Regional  systems.  
During  2011  we  accounted  for  approximately  82%  of  all  the  sewage  produced  in  the  municipalities  in 
which we operated in the State of São Paulo.  We installed 184,900, 233,500 and 246,400 new sewage 
connections in 2009, 2010 and 2011, respectively. 

Sewage System 

The  purpose  of  our  sewage  system  is  to  collect  and  treat  sewage  and  to  adequately  dispose  of  the 
treated  sewage.   As  of  December 31,  2011,  we  were  responsible  for  the  operation  and  maintenance  of 
45,073  kilometers  of  sewage  lines,  of  which  approximately  23,645  kilometers  are  located  in  the  São 
Paulo metropolitan region and 21,428 kilometers are located in the Regional systems, respectively. 

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.   Sewage  lines  larger  than  0.5 meters  in  diameter  are 
primarily  made of concrete.  Our sewage system is generally designed to operate by gravitational flow, 
although  pumping  stations  are  required  in  certain  parts  of  the  system  to  ensure  the  continuous  flow  of 
sewage.  Where pumping stations are required, we use sewage lines made of cast iron. 

The  public  sewage  system  operated  by  us  was  structured  in  order  to  receive  industrial  sewage  and 
sewage from non-domestic sources for treatment together with domestic sewage.  Industrial sewage has 
physical,  chemical  and/or  biological  characteristics  that  are  qualitatively  different  from  household 
effluents.   As  a  result,  the  discharge  of  industrial  sewage  into  the  public  sewage  system  is  subject  to 
compliance with specific legal demands with the purpose to protect the sewage collection and treatment 
systems, the health of operators and the environment.  The current environmental legislation establishes 
standards for the discharge of these effluents into the public sewage system.  These standards are defined 
in  Article 19A  of  State  Decree  No.  8,468  dated  September 8,  1976.   To  ensure  compliance  with 
legislation,  periodic  audits  of  the  sewage  produced  by  all  industrial  clients  are  conducted,  and  we  also 
request self-monitoring reports from non-domestic sewage-producing sources. 

The  discharge  of  these  effluents  into  the  public  sewage  system  is  based  on  technical  and 
administrative procedures.  Before the discharge is permitted, we carry out acceptance studies that assess 
the  capacity  of  the  public  sewage  system  to  receive  the  discharge  as  well  as  the  compliance  with 
regulations.  Upon the conclusion of these studies, the technical and commercial conditions for receiving 
the  discharge  are  established,  which  are  then  formalized  in  a  document  signed  by  us  and  the  effluent 

44 

 
   
   
   
   
   
   
   
producer.   Failure  to  comply  with  these  conditions  can  lead  to  the  application  of  penalties  and  the 
obligation  of  the  effluent  producer  to  conduct  the  necessary  adjustments  in  a  given  time  frame.   Non-
compliance  with  these  penalties  and  adjustments  may  ultimately  result  in  the  suspension  of  the 
connection and notification of the environmental protection agency (Companhia Ambiental do Estado de 
São  Paulo),  or  the  CETESB,  in  order  for  the  applicable  measures  to  be  taken.   Effluents  from  our 
treatment facilities must comply with effluent limitation guidelines and observe the water quality of the 
receiving water bodies established by federal and state legislation.  Effluent limitation guidelines consist 
of a set of parameters that must be verified before the effluents are discharged into a water body.  Water 
quality  standards  are  based  on  the  classification  of  water  bodies,  and  take  into  account  the  current  or 
expected use of water.  These standards will become more rigorous according to the importance of the use 
of water.   

We considered the condition of the sewage lines in the São Paulo metropolitan region to be adequate 
as of the date of this annual report.  Due to greater volume of sewage collected, a higher population and 
more extensive commercial and industrial development, the sewage lines in the São Paulo metropolitan 
region are more deteriorated than those of the Regional systems.  To counter the effects of deterioration, 
we  maintain  an  ongoing  program  for  the  maintenance  of  sewage  lines  intended  to  address  anticipated 
fractures arising from obstructions caused by system overloads. 

Unlike  the  São  Paulo  metropolitan  region,  the  countryside  region  does  not  generally  suffer 
obstructions caused by sewage system overload.  The coastal region, however, experiences obstructions 
in its sewage lines primarily due to infiltration of sand, especially during the rainy season in the summer 
months.   In  addition,  the  sewage  coverage  ratio  in  the  coastal  region  is  significantly  lower  than  in  the 
other  regions  served  by  us,  with  approximately  57%  of  all  residences  in  the  coastal  region  currently 
connected to our sewage network as of December 31, 2011.  

New sewage connections are made on substantially the same basis as connections to water lines:  we 
assume  the  cost  of  installation  for  the  first  20  meters  of  sewage  lines  from  the  sewage  network  to  all 
customers’ sewage connections and the customer is responsible for the remaining costs. 

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

Sewage Treatment and Disposal 

In  2011,  approximately  68%  and  92%  of  the  sewage  we  collected  in  the  São  Paulo  metropolitan 
region  and  the  Regional  systems,  respectively,  or  76%  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 limited capacity.  Flows in excess of this capacity are discharged directly, untreated, to 
inland  waters  and  the  Atlantic  Ocean.   We  currently  operate  481  sewage  treatment  facilities  and nine 
ocean outfalls.  

We  operate  490  activated  sewage  treatment  facilities,  of  which  the  five  largest,  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  countryside  region,  treatment  consists  largely  of  stabilization  ponds  where  the  organic  matter  is 
treated  and  discharged  to  receiving  waters.   There  are  392  secondary  treatment  facilities  in  the 
countryside region that have treatment capacity of approximately 13.0 cubic meters of sewage per second. 

The majority of sewage collected in the coastal region receives treatment and disinfection and is then 
discharged  into  rivers  and  into  the  Atlantic  Ocean  through  our  ocean  outfalls.   We  have  75  sewage 
treatment facilities in the coastal region.   

45 

 
   
   
   
   
   
   
Our sewage collection system is 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  discharged 
untreated into receiving waters.  We are a party to a number of legal proceedings related to environmental 
matters.   See  “Item 8.A.  Financial  Information—Consolidated  Statements  and  Other  Financial 
Information—Legal  Proceedings.”   In  addition,  our  capital  expenditure  program  includes  projects  to 
increase the amount of sewage that we treat.  See “Item 4.A. History and Development of the Company—
Capital  Expenditure  Program”  and  “4.B  Business  Overview—Government  Regulation—Environmental 
Regulation—Sewage Requirements.”   

Sludge Disposal 

In the São Paulo metropolitan region, the treatment process used by most treatment facilities is the 
activated  sludge  process,  where  there  is  a  liquid  phase  and  a  solid  phase  which  generates  sludge.   The 
activated  sludge  process  was  developed  in  England  in  1914.   It  is  widely  used  for  the  treatment  of 
household and industrial sewage.  The work consists of a system in which a biological mass grows, forms 
flakes,  is  continually  re-circulated  and  put  in  contact  with  organic  matter,  always  with  the  presence  of 
oxygen  (aerobic).   The  activated  sludge  process  is  strictly  biological  and  aerobic,  in  which  the  raw 
sewage and the activated sludge are mixed, agitated and aerated in units known as secondary decanters 
where the solid part is separated from the treated wastewater.  The settled sludge returns to the aeration 
tank or is removed for specific treatment.  

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 2011, we produced 46,450 tons of sludge-dry base, of which 45,595 tons 
were  discharged  into  landfills.   The  remaining  portion  of  the  sludge-dry  base  was  used  as  fertilizer  in 
forest and agriculture projects, fuel development and concrete manufacturing.  

Sludge disposal must comply with State and Federal law requirements, such as Resolution No. 375 of 
August 29, 2006 of the CONAMA, Federal Law No. 12,305/2010, Federal Decree No. 7,404/2010, State 
Law No. 12,300/2006 and State Decree No. 54,645/2009. 

Principal Markets in Which We Operate 

As of December 31, 2011, we operated water and sewage systems in 363 of the 645 municipalities in 
the State of São Paulo.  In addition, we currently supply water on a wholesale basis to six municipalities 
located in the São Paulo metropolitan region and the municipality of Sumaré with an urban population of 
approximately 3.7 million.

Competition  

We  believe  there  are  at  least  two  reasons  behind  a  possible  increase  in  our  participation  in  the 
domestic  sanitation  market.   In  the  State  of  São  Paulo,  there  are  approximately  274  municipalities  that 
operate their own water and sewage systems and that collectively have a population of approximately 13 
million, or approximately 33% of the population of the State of São Paulo, excluding the population of 
the municipalities to which we provide water services on a wholesale basis.  Given our scale, we are well 
positioned  to  capture  opportunities  in  these  municipalities.   In  comparison  to  the  companies  providing 
water and sewage services outside the State of São Paulo, we believe we have technological advantages 
compared  to  other  water  and  sewage  services  providers,  which  should  result  in  our  competitively 
advantageous position in regions outside the State of São Paulo.  

The competition for municipal concessions arise mainly from the municipalities, as they may resume 
the  water  and sewage  services  that were granted  to us  and  start providing  these  services  directly  to  the 
local  population.   In  this  case,  the  municipal  governments  would  be  required  to  indemnify  us  for  the 
unamortized portion of our investment.  See “—Business Overview—Our Operations—Concessions.”  In 
the past, municipal governments have terminated our concessions agreements before the expiration date.  
Furthermore,  municipal  governments  have  tried  to  expropriate  our  assets  in  an  attempt  to  resume  the 
provision  of  water  and  sewage  services  to  local  populations.   See  “Item 8.A.  Financial  Information—
Consolidated  Statements  and  Other  Financial  Information—Legal  Proceedings.”   We  negotiate  expired 
concession agreements and concession agreements to be expired with the municipalities in an attempt to 
maintain our existing areas of operations.  In the State of São Paulo we face competition from private and 
municipal water and sewage service providers.  

In recent years, we have also experienced an increasing level of competition in the market of water 
supply to large customers.  Several large industrial customers located in municipalities served by us use 
their  own  wells  to  supply  themselves  with  water.   In  addition,  competition  for  the  disposal  of  non-
residential, commercial and industrial sludge in the São Paulo metropolitan region has increased in recent 
years as private companies offer stand-alone solutions inside the facilities of their customers.  We have 
also  established  new  tariff  schedules  for  commercial  and  industrial  customers  in  order  to  assist  us  in 
retaining these customers. For this group of customers, we have a special authorization from ARSESP to 
establish different tariff than the ones that agency establishes for regular consumers.  

Billing Procedures 

The procedure for billing and payment of our water and sewage services is basically the same for all 
customer categories.  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. 

The  most  part  of  the  bills  for  water  and  sewage  services  are  delivered  to  our  customers  in  person, 
mainly  through  one  of  our  employees  or  through  independent  contractors  who  are  also  responsible  for 
reading water meters.  The remainder, by judicial determination, is sent by mail.  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 
after  deducting  average  banking  fees  ranging  from  R$0.29  to  R$1.15 per  transaction  for  collection  and 
remittance of these payments.  

Customers must pay their water and sewage bills by the due date if they wish to avoid paying a fine.  
We  generally  charge  a  penalty  fee  and  interest  on  late  bill  payments.   In  2009,  2010  and  2011,  we 
received payment of 94.7%, 95.5% and 94.8%, respectively, of the amount billed to our retail customers, 
and  93.9%,  95.5%  and  94.7%,  respectively,  of  the  amount  billed  to  those  customers  other  than  State 
entities,  within  30 days  after  the  due  date.   In  2009,  2010  and  2011,  we  received  110.1%,  97.1%  and 
96.0%, respectively, of the amount billed to the State entities.  Amounts in excess of 100.0% reflect our 
recovery of amounts billed in prior years.  With respect to wholesale supply, in 2009, 2010 and 2011, we 
received payment of 68.7%, 58.3% and 54.7%, respectively, of the amount billed within 30 days. 

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.  Part of the water meter monitoring for billing 

47 

 
purposes is carried out by our own personnel, trained and supervised by us and part of it is carried out by 
third-party contractors that employ and train their own personnel whose training we supervise.  

Tariffs 

Tariff adjustments follow the guidelines established by the Basic Sanitation Law and the ARSESP.  
The guidelines also establish procedural steps and the terms for the annual adjustments.  The adjustments 
have to be announced 30 days prior to the effective date of the new tariffs which occur in September, and 
last for a period of at least 12 months.  

Tariffs  have  historically  been  adjusted  once  a  year  and  for  periods  of  at  least  12  months.   We 
increased our tariffs for water and sewage services by 6.8%, 9.0% and 6.7% in August 2004, 2005 and 
2006,  respectively.   On  September 2007,  tariffs  rose  by  4.12%,  except  for  water  supply  and  sewage 
collection tariffs for consumption of more than 20 cubic meters in non-residential categories, which were 
adjusted by the cumulative inflation from August 2006 to July 2007 in the consumer price index (Índice 
Nacional de Preços ao Consumidor Amplo), or IPCA, index published by IBGE, which came to 3.74%. 

See  “—Government  Regulation—Tariff  Regulation  in  the  State  of  São  Paulo”  for  additional 

information regarding our tariffs. 

With  the  publication  of  the  Basic  Sanitation  Law,  the  regulation  of  basic  sanitation  services, 
including  tariff  regulation,  became  the  responsibility  of  an  independent  regulator.  To  exercise  this 
assignment, the State of São Paulo created the ARSESP, which regulates and supervises the services we 
provide  to  the  State  and  also  within  the  municipalities  that  have  agreed  to  its  jurisdiction  through  a 
cooperation agreement entered into by that municipality.   

In regards to municipalities that have not explicitly selected the ARSESP as their regulator, the Basic 
Sanitation Law admits the possibility of that municipality creating other regulatory agencies of their own. 
 In 2007, the municipality of Lins decided to create its own regulatory authority, although having revised 
this  decision  in  2010,  transferring  to  ARSESP  the  regulation  of  the  water  activities  performed  in  Lins, 
including  for  the  setting  of  tariffs.  The  municipality  of  Lins  has  reserved,  however,  the  power  to 
ultimately approve the tariff set by the ARSESP. In 2011, the municipalities in which the hydrographic 
basins of the rivers Piracicaba, Capivari and Jundiaí are located have created a consortium for regulation 
and  supervision  of  our  activities  in  that  area.  See  "   Government  Regulation—Tariff  Regulation  in  the 
State of São Paulo " for additional information.  

As of the date of this annual report, the ARSESP applied the adjustment formula for our tariffs that 
we established on August 29, 2003. This adjustment was developed to better reflect changes in our cost 
structure.  According to this formula, the cost components of the Tariffs Adjustment Index, or IRT, are 
separated into two parts (“Part A” and “Part B”), where “Part A” encompasses all costs related to energy, 
water and sewage treatment  materials; federal, state and local taxes; and financial compensation due to 
use  of  water  resources.   “Part B”  encompasses  all  other  costs  and  expenses.   “Part B”  relates  to  the 
difference  between  the  gross  operating  revenue  and  the  value  of  “Part A”  for  the  same  period.   The 
adjustment  of  “Part A”  is  based  on  the  effective  cost  variation  observed  in  its  components  during  the 
preceding 12-month period.  “Part B” is adjusted by the IPCA index.  The adjustment to the formula used 
by the ARSESP replaced the variable gross operating revenue for the variable cost of reference.   

In  September 2008,  we  adjusted  our  tariffs  by  5.10%  pursuant  to  the  ARSESP’s  authorization.   In 
August 2009,  the  ARSESP  approved  a  4.43%  adjustment  for  our  water  and  sewage  tariffs,  starting  on 
September 11,  2009.   In  August 2010,  the  ARSESP  approved  a  4.05%  adjustment  for  our  water  and 
sewage tariffs, starting on September 11, 2010.  In 2011, we readjusted our prices in 6.83%, starting on 
September  11,  2011.   This  adjustment  was  valid  for  all  municipalities  served  by  us,  except  for  the 
municipalities of São Bernardo do Campo, Lins and Magda, which have different rules and readjustment 
dates.   The  tariffs  in  the  municipality  of  São  Bernardo  do  Campo  are  adjusted  pursuant  a  different 
methodology due to the difference between the tariffs charged in that municipality when we assumed the 
service and the tariffs we were charging in other metropolitan municipalities we serve.  The adjustments 
in São Bernardo do Campo are set so that in September 2012 the tariff charged in this municipality and 
the  tariff  charged  in  the  other  municipalities  of  the  region  will  be  the  same.   With  respect  to  the 
municipality of Lins, our tariff is adjusted in January according to the variation of the IPCA for the last 

48 

 
twelve-month period ended November 30.  In regards to Magda, adjustments are expected to be made by 
2015. 

Until the new tariff structure we propose is approved by the ARSESP, we will continue to use our 
current  tariff  structure.   As  such,  we  currently  divide  tariffs  into  two  categories:   residential  and  non-
residential.   The  residential  category  is  subdivided  into  standard  residential,  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:   (i) commercial,  industrial  and  public  customers;  (ii) “not-for-profit” 
entities that pay 50.0% of the prevailing non-residential tariff;  (iii) government entities that have entered 
into a water loss reduction agreement with us and pay 75.0% of the prevailing non-residential tariff; and 
(iv) public entities that have entered into program agreements, for municipalities with a population of up 
to 30,000 and with half or more classified according to their degree of social vulnerability by the Social 
Vulnerability Index of São Paulo (Índice Paulista de Vulnerabilidade Social), or IPVS, 5 and 6, of the 
SEADE, obtained through the analysis of the 2000 Census figures, and start to receive tariff benefits, in 
accordance with our normative ruling, for the category of public use, at the municipality level.  The tariffs 
are equal to those offered to the commercial/entity of social assistance and that corresponds to 50.0% of 
the public tariffs without contractual provisions referred to in item (iv) above. 

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 fixed demand agreements 
(take-or-pay) with us for at least one-year terms.  In October 2007, the minimum volume for entering into 
these agreements was reduced from 5,000 cubic meters per month to 3,000 cubic meters per month.  We 
believe this tariff schedule will help prevent our commercial and industrial customers from switching to 
the use of private wells.  Since 2008, we have been authorized by the ARSESP to establish tariffs for non-
residential customers, such as industrial and commercial customers, that consume more than 3,000 cubic 
meters per month, with a maximum tariff equal to the tariffs applicable to non-residential customers that 
consume  more  than  50  cubic  meters  per  month.   In  2010,  the  ARSESP  authorized  a  reduction  in  the 
minimum volume of consumption for customers that enter into demand agreements with us to a minimum 
of 500 cubic meters per month.  

We establish separate tariff schedules for our services in each of the São Paulo metropolitan regions 
and  each  of  the  countryside  and  coastal  regions  which  comprise  our  Regional  systems.   Each  tariff 
schedule  incorporates  regional  cross-subsidies,  taking  into  account  the  customers’  type  and  volume  of 
consumption.  Tariffs paid by customers with high monthly water consumption rates exceed our costs of 
providing 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 countryside and coastal regions. 

Sewage charges in each region are fixed and are based on the same volume of water charged.  In the 
São  Paulo  metropolitan  region  and  the  coastal  region,  the  sewage  tariffs  equal  the  water  tariffs.   In  the 
countryside  region,  sewage  tariffs  are  approximately  20.0%  lower  than  water  tariffs.   Wholesale  water 
rates  are  the  same  for  all  municipalities  served.   We  also  make  available  sewage  treatment  services  to 
those  municipalities  in  line  with  the  applicable  contracts  and  tariffs.   In  addition,  various  industrial 
customers pay an additional sewage charge, depending on the characteristics of the sewage they produce.  

Each category and class of customer pays tariffs according to the volume of water consumed.  The 
tariff paid by a certain category and class of customer increases progressively according to the increase in 
the volume of water consumed.  The following table sets forth the water and sewage services tariffs by 
(i) customer category and class and (ii) volume of water consumed charged during the years and period 
stated in the São Paulo metropolitan region.

Both in 2010 and 2011, the average tariff calculated for the Regional systems was approximately 

30% below the average tariff of the São Paulo metropolitan region.  

Regarding  the  new  tariff  structure  that  ARSESP  aims  to  implement,  since  2008  it  has  been 
developing new concepts that might be included in the tariff structure and adjustment formula but it has 
so  far  regulated  our  tariff  structure  and  adjustments  according  to  the  same  structure  and  adjustment 
formula that we ordinarily follow.   

On July 22, 2009, the ARSESP released a Technical Note (Nota Técnica) regarding the methodology 
for the tariff adjustment process and submitted it for public comments.  On August 12, 2009, the ARSESP 
informed  that  the  new  methodology  would  not  be  applied  for  the  2009  adjustment.   The  ARSESP  is 
currently working on the development and improvement of its new methodology and it expects to release 
a revised tariff structure and adjustments formula in 2012. 

 In March 2011, the ARSESP published the tariff review schedule and opened a public hearing for 
the proposed methodology for the calculation of the weighted average cost of capital (WACC).  In May

2011, the ARSESP released a regulatory post-tax weighted average cost of capital of 8.06%. In October 
2011,  we  presented  to  the  ARSESP  a  detailed  business  plan  that  disclosed  requested  information 
regarding  our  income,  expenses  and  capital  expenditures,  so  that  the  ARSESP  could  set  an  adjustment 
formula  for  our  tariffs.  In  January  2012,  the  ARSESP  commenced  a  public  consultation  regarding  our 
methodology for tariff revisions. The public consultation aims to: (i) set the initial framework for periodic 
tariff revisions for all municipalities we serve that are under the supervision of the ARSESP; (ii) discuss 
the  criteria  adopted  to  determine  the  cost  of  services,  the  tariff  framework  and  the  subsidies  policy, 
among  other  issues;  (iii)  create  a  methodology,  standards  and  procedures  for  future  revisions  and 
adjustments;  and  (iv)  ensure  the  broad  involvement  of  municipalities,  concessionaires,  consumers, 
investors and others. 

In 2010, the ARSESP defined the rules to evaluate our asset base (Rule No. 156/2010). By August 
We have hired companies to conduct such an evaluation using this methodology and by August 2012, we 
will present to the ARSESP the evaluation of our asset base according to reposition cost and weighted by 
the  respective  usage  ratio  in  accordance  with  ARSESP  Rule  No.  156/2010,  on  which  our  regulatory 
remuneration will be based.  We will also present ARSESP with a detailed business plan that will serve as 
a  basis  for  the  final  tariff  methodology  process  to  be  released  by  the  ARSESP  in  the  near  future.   In 
September  2012,  we  expect  to  receive  the  ARSESP’s  preliminary  average  tariff  proposal  and  the 
applicable efficiency gains factor that we will be required to include in the tariff structure proposal that 
the  ARSESP  will  then  request  from  us.  By  October  2012,  we  expect  to  be  able  to  propose  such  tariff 
structure,  and  our  preliminary  average  tariff,  efficiency  gains  factor  and  tariff  structure  will  then  be 
submitted for public hearing. The ARSESP estimates that a final public hearing at which our preliminary 
average  tariff,  efficiency  gains  factor  and  tariff  structure  will  be  subjected  to  public  scrutiny  will  be 
scheduled  by  November  2012.  The  aforementioned  schedule  may,  however,  suffer  alterations  or  be 
subject to delays.  

Marketing Channels 

As  of  December 31,  2011,  we  were  the  concessionaire  for  the  provision  of  water  supply  and 
collection, treatment and disposal of sewage services directly to end consumers for 363 municipalities of 
the State of São Paulo.  We also supply water on a wholesale basis to six municipalities located in the São 
Paulo metropolitan region and the municipality of Sumaré.  It is the responsibility of these municipalities 
to  then  distribute  the  water  to  end  consumers.   We  provide  sewage  services  to  five  of  these 
municipalities.   Because  of  our  distribution  infrastructure,  end  consumers  to  whom  we  offer  water 
services  on  a  wholesale  basis  cannot  alternatively  acquire  such  services  directly  from  us.   For  more 
information on service concessions, see “4.B. Business Overview—Wholesale Operations.”   

Energy Consumption   

Energy is essential to our operations, and as a result we are one of the largest users of energy in the 
State  of  São  Paulo.   In  the  year  ended  December 31,  2011,  we  used  1.76%  of  the  total  energy 
consumption in the State of São Paulo.  To date, we have not experienced any major disruptions in energy 
supply.  Any significant disruption of energy to us could have a material adverse effect on our business, 
financial  condition,  results  of  operations  or  prospects.   See  “Item 3.D.  Risk  Factors—Risks  Relating  to 
Our Business—We are exposed to risks associated with the provision of water and sewage services.”  

Energy prices have a significant impact on our results of operations.  An average increase in energy 
prices of 17.6% in 2003 negatively affected our results of operations in 2004.  In 2011, 44% of our total 
energy  consumption  occurred  within  the  “free  market”,  where  we  can  more  efficiently  negotiate  the 
supply of energy.  This energy was provided by Companhia Energética São Paulo, or CESP, pursuant to a 
long-term contract expiring in October 2012. AES Tiête (39%) and Tractebel Energia S.A. (61%) have 
already been hired to provide these services for the remainder of 2012 and until 2015. 

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 by means of public bids involving 
major Brazilian and international insurance companies that operate in Brazil.  As of December 31, 2011, 
we had paid a total aggregate amount of R$9.3 million in premiums, covering R$2.1 million on assets, 
third-party liabilities and D&O insurance.  We do not have insurance coverage for business interruption 

51 

 
risk because we do not believe that the high premiums for such insurance are justified by the low risk of 
major interruption of our activities.  In addition, we do not have insurance coverage for liabilities arising 
from  water  contamination  or  other  problems  involving  our  water  supply  to  customers  and  for 
environmental related liabilities and damages.  We believe that we maintain insurance at levels customary 
in Brazil for our type of business. 

Environmental Matters 

Our  environmental  policy,  which  we  revised 

in  January 2008,  established  environmental 
management directives that allow us to become a contributing force to environmental sustainability and 
excellence.  These directives are based on a systematic approach to the environment, which allow us to 
develop  a  plan  that  integrated  economic,  environmental  and  social  dimensions  of  our  work  with 
sustainable use of natural resources. 

In order to coordinate the environmental demands with the specific needs of the different places we 
operate, we have implemented 20 Environmental Management Centers (Núcleos de Gestão Ambiental), 
or NGAs.  The NGAs are closely involved in operational matters, providing decision-making support at a 
local  level  and  seeking  to  ensure  that  environmental  guidelines  are  respected  throughout  our 
organization.   In  this  manner,  they  help  contribute  to  the  ongoing  improvement  of  our  environmental 
performance. 

We have the following environmental management programs: 

(cid:131)  execution of a Environmental Management System, or EMS, and acquisition of ISO 14001 

certification to our sewage and water treatment facilities.  We received the certifications for 50 
 sewage treatment facilities, including those located in the São Paulo metropolitan, countryside 
and coastal regions.  65 of our water treatment facilities and sewage treatment facilities have 
implemented the EMS, and we expect to extend it progressively to our remaining installations;

(cid:131) participation in the Carbon Disclosure Project (CDP) and adherence to the Carbon Disclosure 

Project CDP Supply Chain; 

(cid:131) conception and formation of the Corporate Management of Greenhouse Gas Program (Programa

stakeholders ; 

(cid:131) our institutional representation in the State and National Systems of Water Resources 

Management, including training of company representatives to participate in councils of the 
National and State Systems for the Management of Water Resources (Sistemas Nacional e 
Estadual de Gerenciamento de Recursos Hídricos), training of the representatives for 
participation in the process of establishing criteria for the charging of water usage, monitoring of 
water basin plans (Planos das Bacias), water bodies classification programs and the 
establishment or review of specific legislation on the matter; 

(cid:131) the structuring of educational activities related to analyzing, managing, and communicating 

environmental risks;  

(cid:131) implementation of the SABESP 3-Rs Program (Programa SABESP 3Rs) for the reduction, re-use 

and recycling of waste of administrative activities, a program involving the two largest 
administrative areas of our Company with plans to include all other administrative areas.

In  addition  to  corporate  environmental  management  initiatives,  since  2008  we  launched  several 
projects to benefit the environment by engaging the community and third parties with non-governmental 
organizations, including: 

(cid:131)       Oil Recycling Program (Programa de Reciclagem de Óleo de Fritura), or PROL;

Climate Change Regulations:  Reduction of Greenhouse Gases (GHG) 

We  are  required  to  comply  with  laws  and  regulations  related  to  climate  change,  including 

international agreements and treaties to which Brazil is a signatory. 

The São Paulo State Climate Change Policy (Law No. 13,798), enacted on November 9, 2009, seeks 
to  reduce  global  emissions  of  carbon  dioxide  by  20.0%  by  2020  compared  with  2005  levels.   Brazil’s 
Climate  Change  Policy  (Law  No.  12,187),  enacted  on  December 29,  2009,  establishes  a  voluntary 
national  commitment  to  reduce  Brazil’s  currently  projected  GHG  emissions  for  2020  by  a  percentage 

53 

 
   
between  36.1%  and  38.9%.   If  legislation  requires  us  to  reduce  our  emissions,  we  may  do  so  by 
transforming biogas from the treatment of sewage into energy, for example, which may lead to potential 
economic gains. 

We have begun significant initiatives, such as the corporate program for water loss reduction and the 
implementation of small hydroelectric power plants, to reduce GHG emissions during the coming years.  
We recently launched the Aquapolo project, the fifth largest project in the world to use reclaimed water 
production  for  industrial  purposes,  which  uses  treated  sewage  as  input.   This  project,  capable  of 
producing 1,000 liters per second (Ps) of reclaimed water, will increase the supply of treated water for the 
São  Paulo  metropolitan  region  and  may  potentially  reduce  GHG  emissions.   Our  investments  in  the 
Aquapolo  project  amounted  to  approximately  R$252 million.   We  created  our  inventory  of  GHG 
emissions for the year 2008 and are verifying our inventories for the years 2009 and 2010. Moreover, we 
are developing a management program for GHG emissions.  The program includes studies of impacts and 
risks related to climate change and the study of potential scenarios based on our emissions of GHG.  

At this point, it is still not possible to predict if climate change policies will provide opportunities or 
generate new costs for us.  Reducing our emissions of carbon dioxide will involve costs and expenses in 
implementing more stringent control mechanisms, adopting pollution prevention measures and actions to 
minimize the generation of GHGs.  We may not receive financial incentives to offset all or part of these 
costs.  In addition, if limitations in GHG emissions affect our supply chain and increase our costs, we may 
not be able to pass on these costs to our end consumers.  See “4.B.  Business Overview—Tariffs.” 

Regulation of GHG emissions could also benefit us in the short term, since we may be able to obtain 
subsidies,  financial  investments  and  tax  incentives  for  projects  to  protect  and  restore  water  sources, 
conserve  water,  treat  sewage,  conserve  energy,  increase  energy  efficiency,  and  promote  self-generated 
energy, among other projects that seek to reduce the impact of climate change. 

Carbon Disclosure Project 

(cid:131)  Carbon Disclosure Project Investors.  We participate in the Carbon Disclosure Project – CDP, a 

global initiative focused on the financial risks related to climate change.  Through this project, main 
international institutional investors ask the world’s largest companies to demonstrate that they are 
managing carbon effectively.  We have received and responded the project’s questionnaires since 
2006.  The companies that opt to have their answers disclosed to the public, such as our case, have 
their answers published in an international website of public interest.  The questionnaire asks 
mainly questions related to the aspects of climate change and corporate governance, the physical, 
financial and regulatory effects of climate change, and opportunities that affect or could positively 
or negatively affect us.  

(cid:131)  Carbon  Disclosure  Project  Supply  Chain.   On  December 2010,  we  adhered  to  the  Carbon
Disclosure  Project  –  CDP  Supply  Chain  2011.   The  project  seeks  to  encourage  the  adoption of  a
standard  methodology  by  our  main  suppliers  of  goods  and  services  to  measure  risks  related  to
climate  change  and  GHG  emissions.  We  have  invited  97  of  our  main  suppliers  of  goods  and
services to join the CDP Supply Chain, from which 20% have joined the project.  

  Physical Effects of Climate Change 

Since our financial performance is closely linked to climate patterns that influence in the availability 
of water (in terms of quantity and quality of water resources), extreme weather conditions may adversely 
affect  our  business  and  operations.   If  long-term  climate  change  causes  significant  alterations  in 
environmental conditions, such as an increase in the frequency of extreme weather conditions, this could 
affect the quality and quantity of water available for abstraction, treatment and supply, affecting the costs 
of services and tariffs.   

An  increase  in  heavy  rainfall  can  impact  water  quality  and  the  regular  operation  of  water  sources, 
including  abstraction  of  water  from  our  dams,  through  increased  soil  erosion,  silting,  pollution  and 
eutrophication of aquatic ecosystems.  In addition, increased flows of rainwater into sewage systems may 
overwhelm the capacity of sewage treatment plants.  We may need to build larger reservoirs, since it is 
not  feasible  to  increase  the  size  of  our  existing  reservoirs,  or  increase  operational  capacity  by  further 
automating  our  existing  equipment.   To  increase  automation,  we  would  need  to  purchase  and  operate 
tools  to  measure  dam  levels  and  volumes,  river  output  and  the  rain  in  hydrographic  basins,  create 

54 

 
  
  
   
  
mathematical  models  for  real  time  operations,  and  train  technicians  to  operate  these  systems.   As  an 
alternative, we may need to implement new production systems. 

In the case of prolonged periods of drought, for example, reduced water levels in dams can cause an 
increase in the concentration of plant matter by increasing eutrophication and, consequently, increasing 
water  treatment  costs  and  operational  complexity.   In  addition,  prolonged  periods  of  drought  in 
watersheds such as the São Paulo metropolitan region, where most of our production is concentrated, may 
result in the growth of vegetation in the reservoir flooding areas, which can impact water quality due to 
the  accumulation  of  organic  matter.   In  such  cases  our  production  costs  may  increase,  affecting  our 
financial margins and the quality of water we produce.  Droughts also lower reservoir levels available for 
hydroelectric plants, which may lead to power shortages, particularly since hydroelectric power accounts 
for most of Brazil’s electric energy supply.  A lack of rainwater could lead to instability in domestic water 
supplies  and  in  sewage  collection  and  treatment  services,  which  could  damage  our  reputation.   In 
addition, because we are one of the largest consumers of electricity in the State of São Paulo, a potential 
increase in electricity tariffs due to a shortage of hydroelectric power could have a significant economic 
impact on us.  

We are also the concessionaire for water and sewage services for all the coastal municipalities of the 
State  of  São  Paulo.   A  rise  in  the  sea  level  would  result  in  increased  salinity  of  inland  water  supplies, 
which may affect water treatment in these areas.  Rising sea levels may also increase infiltration rates and 
alter the runoff regime of the sewage systems, which may affect the sanitary system. 

Extreme  climate  changes  may  also  affect  the  extraction,  production  and  transportation  of  the 
materials necessary for our operations, such as water treatment materials, and may lead to an increase in 
the  cost  of  these  materials.   A  rise  in  air  temperature  could  also  increase  consumer  demand  for  water, 
increasing the need to expand both water supply and sewage treatment. 

See  “Item 3.D.  Risk  Factors—Risks  Relating  to  Our  Business—The  enactment  of  new  laws  and 
regulations relating to climate change and the change in existing regulation, as well as the physical effects 
of climate change, may result in increased liabilities and increased capital expenditures, which could have 
a material adverse effect on us”.  

Government Regulation 

Basic sanitation services in Brazil are subject to an extensive federal, state and local legislation and 

regulation that, among other matters, regulates: 

(cid:131)  the granting of concessions to provide water and sewage services;

(cid:131) the development of public private partnerships; 

(cid:131) the need of a public bidding process for the appointment of private water and sewage services 

providers; 

(cid:131)  the need of setting up an agreement for the appointment of public water and sewage services 

providers; 

(cid:131) the joint management of public services through cooperation, allowing for a program agreement 

without the need for a public bidding process for the service provider, subject to the condition that 
the planning, execution and monitoring activities are not executed by the service provider; 

(cid:131) minimum requirements for water and sewage services; 

(cid:131) water usage; 

(cid:131) water quality and environmental protection; and

General 

Pursuant  to  Article  23  of  the  Brazilian  Constitution,  water  and  sewage  services  are  the  joint 
responsibility of the federal government, the states and the municipalities.  Article 216 of the Constitution 
of  the  State  of  São  Paulo  provides  that,  by  law,  the  State  must  provide  the  conditions  for  efficient 
management  and  adequate  expansion  of  water  and  sewage  services  rendered  by  its  agencies  and  State-
controlled companies or any other concessionaire under its control.  State law authorized our formation to 
plan, provide and operate water and sewage services in the State and also acknowledged the autonomy of 
the municipalities. 

Pursuant to Article 175 of the Brazilian Constitution, the rendering 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 render these services directly or through a concession granted to a third party. 

In Brazil, there are three federal legal regimes for contracting water and sewage services:  (i) public 
concessions,  regulated  by  Law  No.  8,987/1995,  which  require  a  prior  public  bidding  process;  (ii) 
administration  of  public  services  through  cooperation  agreements  between  the  federal  government  and 
local  public  authorities  at  State  and  municipal  level  without  the  need  for  a  public  bidding  process, 
regulated by the Public Consortia and Cooperation Agreement Law; and (iii) public-private partnerships, 
regulated  by  Law  No.  11,079/2004,  used  to  grant  concessions  to  private  companies  to  provide  public 
services  and  used  in  relation  with  construction  works  associated  with  the  provision  of  public  services.  
Until  2005,  we  had  adopted  the  regime  for  public  concessions.   Following  the  entry  into  force  of  the 
Public  Consortia  and  Cooperation  Agreement  Law,  we  adopted  the  administration  of  public  services 
through cooperation agreements, which can be used alongside the other two regimes.  

The  Public  Consortia  and  Cooperation  Agreement  Law  and  the  Basic  Sanitation  Law  have  caused 
significant impacts in the development of the state sanitation policy and the regulatory structuring of the 
industry. 

Because  we  are  the  legal  concessionaire  for  the  State  of  São  Paulo  for  water  and  sewage  services, 
serving  approximately  59%  of  the  State’s  population  and  providing  sanitation  services  through 
concession  agreements,  the  Consortium  Law  affects  us  on  the  expiry  of  our  concession  agreements 
entered  into  in  the  1970s  when  the  Brazilian  Sanitation  Plan  (Plano  Nacional  de  Saneamento),  or 
PLANASA, was created.  The Consortium Law has caused important changes in the relationship among 
municipalities,  states  and  public  sanitation  service  providers,  most  notably  in  mixed  capital  companies, 
such  as  us,  because  of  the  implementation  of  the  program  agreements  as  a  substitute  for  concession 
agreements. 

In  addition,  the  Basic  Sanitation  Law  in  its  role  as  a  general  guideline  for  the  development  of  the 
Brazilian sanitation industry, addresses the conditions for the delegation of water and sewage services, the 
exercise of ownership by the granting authority and the regulatory conditions for the industry.  The Basic 
Sanitation Law also provides for a significant amendment to Article 42 of the Concessions Law, which 
establishes the termination of concessions prior to the expiration date and the reversibility conditions for 
unamortized assets.  The amendment requires that the service provider be compensated for unamortized 
assets, prioritizing an agreement between the parties setting out the criteria for calculation and payments 
of indemnity. 

The Basic Sanitation Law 

On  January 5,  2007,  the  Federal  Law  No.  11,445,  or  the  Basic  Sanitation  Law,  was  enacted, 
establishing nationwide guidelines for basic sanitation and seeking to create appropriate solutions for the 
situation  of  each  state  and  municipality,  facilitating  the  technical  cooperation  between  the  state  and 
municipalities.   In  addition,  the  federal  government  will  enact  its  public  policy  to  facilitate  access  to 
financing  alternatives  that  are  compatible  with  the  costs  and  terms  of  the  sanitation  industry,  in 
substitution of the PLANASA model.  On June 21, 2010, the federal government enacted Federal Decree 
No. 7,217, regulating the Basic Sanitation Law.  See “Risk Factors—Risks Relating to our Business—We

cannot anticipate the effects that further developments of the Basic Sanitation Law and its interpretation 
will have on the basic sanitation industry in Brazil and on us.”   

The  Basic  Sanitation  Law  establishes  the  following  principles  for  basic  sanitation  public  services:  
universalization,  integrality,  efficiency  and  economic  sustainability,  transparency  of  actions,  social 
control and integration of infrastructure and services with the management of water resources.  It does not 
define the ownership of the sanitation services, but establishes the minimum liability for the exercise of 
ownership,  such  as  the  development  of  the  sanitation  plan,  definition  of  the  person  responsible  for 
regulation and control, establishment of the rights and obligations of the users and of the social control 
mechanisms.  It also defines the regionalized performance of the services (i.e., one single provider serves 
two or more owners, for which there may be one plan for the combination of services). 

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

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

The  Basic  Sanitation  Law  also  establishes  the  criteria  for  the  reversal  of  assets  at  the  time  of 
termination of the agreement and with regard to the concessions, such as those that have expired or are 
effective for an indefinite term, or those that were not formalized by an agreement.  In addition, the Basic 
Sanitation  Law  provides  the  basis  for  calculating  the  amount  of  an  indemnity  due,  which  must  be 
calculated by a specialized institution chosen by mutual agreement between the parties. 

Pursuant to the Basic Sanitation Law, the parties of the concession may enter into an agreement with 
respect to the payment of the indemnification due to the concessionaire.  However, in the absence of an 
agreement,  the  Basic  Sanitation  Law  establishes  that  the  indemnification  must  be  paid in  no  more  than 
four equal and successive annual installments, with the first installment payable by the last business day 
of the fiscal year in which the assets are reversed.  

Tariff Regulation in the State of São Paulo 

The tariffs for our services are subject to Federal and State regulation. 

On December 16, 1996, the governor of the State of São Paulo issued a decree which approved the 
existing tariff system and allowed us to continue to set our own tariffs.  We used to set our tariffs based 
on the general objectives of maintaining our financial condition and preserving “social equality” 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: 

(cid:131)       category of use;   

(cid:131)       capacity of the water meter;   

(cid:131)       characteristics of consumption;   

(cid:131)       volume consumed;   

(cid:131)       fixed and floating costs;   

(cid:131)       seasonal variations of consumption; and   

(cid:131)       social and economic conditions of residential customers. 

With  the  enactment  of  the  Basic  Sanitation  Law  and  Federal  Consortium  Law,  we  are  prohibited 
from  planning,  overseeing  and  regulating  services,  which  includes  determining  the  tariff  policy  to  be 
adopted.  Such activities are to be exercised by the owner of the concession.  Other than the responsibility 
for planning, the remaining activities may not be delegated.   

57 

 
The current tariff structure maintains different tariff schedules, depending upon whether a customer 
is located in the São Paulo metropolitan region or the Regional systems.  There are four levels of volume 
consumed  for  each  category  of  customer,  except  for  the  residential  social  and  favelas    (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.  Customers are billed on a 
monthly basis.  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 nonphysical 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  are  also  authorized  to  enter  into  individual  contracts  with  certain  customers, 
such as municipalities, to supply water or sewage services on a wholesale basis. 

Before the enactment of the Basic Sanitation Law in 2007, we were subject to a federal law which 
limited the return on assets for water and sewage services to 12.0% per annum.  Return on our assets was 
calculated  using  operating  income  (before  financial  and  certain  other  expenses)  measured  against  our 
operational  assets  (property,  plant  and  equipment  and  certain  other  assets),  based  on  our  financial 
statements prepared in accordance with the accounting practices adopted in Brazil, or Brazilian GAAP.  
The Basic Sanitation Law revoked this law and extinguished this rule.  Pursuant to the Basic Sanitation 
Law, tariff regulation is to be performed by an independent regulatory entity.  Municipalities can either 
create  their  own  regulatory  agency  or  delegate  tariff  regulation  to  the  ARSESP.   With  respect  to  the 
criteria to calculate the return on assets, on July 30, 2010, the ARSESP adopted a new methodology for 
the calculation of return on assets, which uses the replacement cost of the assets (assuming replacement 
with  new  assets)  as  a  basis  for  the  calculation.   Although  the  ARSESP  has  proceeded  with  public 
consultations  on  tariff  methodology  and  has  indicated  that  it  will  implement  the  new  methodology  by 
2012, we cannot assure you when the new rules will be enacted.  Meanwhile, the ARSESP has not altered 
the tariff formula and has continued to apply the same methodology as in prior years.  

Since  2008,  the  ARSESP  has  been  developing  new  concepts  in  the  tariff  structure  and  adjustment 
formula.  In July 30, 2010, the ARSESP published Resolution No. 156 establishing the methodology and 
general  criteria  for  the  definition  of  our  regulatory  asset  base,  in  order  to  move  forward  with  the  tariff 
review process and to define the initial parameters of the auditing process that the ARSESP will have to 
conduct pursuant to the terms of the Basic Sanitation Law.  The methodology has been defined and, in 
general terms, assets will be evaluated by reposition costs and weighted by the respective usage ratio.  

In March 2011, the ARSESP published the tariff review schedule and opened a public hearing for the 
proposed methodology for the calculation of the weighted average cost of capital (WACC).  In May 2011, 
the ARSESP released a regulatory post-tax weighted average cost of capital of 8.06%. In October 2011, 
we presented to the ARSESP a detailed business plan that disclosed requested information regarding our 
income, expenses and capital expenditures, so that the ARSESP could set an adjustment formula for our 
tariffs.  

In January 2012, the ARSESP commenced a public consultation regarding our methodology for tariff 
revisions. The public consultation aims to: (i) set the initial framework for periodic tariff revisions for all 
municipalities we serve that are under the supervision of the ARSESP; (ii) discuss the criteria adopted to 
determine  the  cost  of  services,  the  tariff  framework  and  the  subsidies  policy,  among  other  issues;  (iii) 
create a methodology, standards and procedures for future revisions and adjustments; and (iv) ensure the 
broad involvement of municipalities, concessionaires, consumers, investors and others. 

In  2010,  the  ARSESP  defined  the  rules  to  evaluate  our  asset  base  (Rule  No.  156/2010).  We  have 
hired  companies  to  conduct  such  an  evaluation  using  this  methodology  and  by  August  2012,  we  will 
present to the ARSESP the evaluation of our asset base according to reposition cost and weighted by the 
respective  usage  ratio  in  accordance  with  ARSESP  Rule  No.  156/2010,  on  which  our  regulatory 
remuneration will be based.  We will also present ARSESP with a detailed business plan that will serve as 
a  basis  for  the  final  tariff  methodology  process  to  be  released  by  the  ARSESP  in  the  near  future.   In 
September  2012,  we  expect  to  receive  the  ARSESP’s  preliminary  average  tariff  proposal  and  the 
applicable efficiency gains factor that we will be required to include in the tariff structure proposal that 
the  ARSESP  will  then  request  from  us.  By  October  2012,  we  expect  to  be  able  to  propose  such  tariff 
structure,  and  our  preliminary  average  tariff,  efficiency  gains  factor  and  tariff  structure  will  then  be 
submitted for public hearing. The ARSESP estimates that a final public hearing at which our preliminary 

58 

 
average  tariff,  efficiency  gains  factor  and  tariff  structure  will  be  subjected  to  public  scrutiny  will  be 
scheduled  by  November  2012.  The  aforementioned  schedule  may,  however,  suffer  alterations  or  be 
subject to delays. We cannot anticipate the additional changes that the ARSESP will implement on our 
tariff structure and adjustment formula or the effects that these changes will have on us.  If the changes 
are unfavorable to us, they could materially and adversely affect us. 

Furthermore,  since  Law  No.  11,445  permits  municipalities  to  create  their  own  regulatory  agencies 
rather  than  being  subjected  to  overview  by  the  ARSESP,  a  number  of  municipalities  created  their  own 
regulatory  agencies.  The  municipality  of  Lins,  which  had  decided  in  2007  to  create  its  own  regulatory 
authority, revised this decision in 2010 and transferred the regulation of the water activities performed in 
Lins, including the setting of tariffs to the ARSESP. Lins has retained, however, the power to ultimately 
approve the tariff set by the ARSESP. The municipalities of São Bernardo do Campo and Magda retained 
the  power  to  readjust  the  tariffs  applied  therein.  Additionally,  the  municipalities  in  which  the 
hydrographic basins of the rivers Piracicaba, Capivari and Jundiaí are located have created a consortium 
for regulation and supervision of our activities in that area. As this entity has recently been created, we 
cannot  predict  how  it  may  implement  regulatory  changes  that  may  affect  our  activities.  If  other 
municipalities create new agencies, we will be subject to their regulation, supervision and limitations to 
our services.  See “Risk Factors—Risks Relating to Our Business—We cannot anticipate the effects that 
further developments of the Basic Sanitation Law and its interpretation will have on the basic sanitation 
industry in Brazil and on us”. 

Consumer Relations in the State of São Paulo 

Pursuant to the Basic Sanitation Law, in 2009, the ARSESP enacted certain rules establishing (i) the 
general  conditions  for  the  services  we  render,  (ii) the  communication  process  for  any  failure  in  our 
services; (iii) penalties for deficiencies in the provision of basic sanitation services; and (iv) procedures 
for  confidential  treatment  of  our  clients’  private  information.   We  are  currently  evaluating  the 
enforceability and legality of some of these rules.  Implementation of these rules started during 2011 and 
is  expected  to  continue  for  the  next  few  years.   The  implementation  of  these  rules  will  impact  our 
commercial and operations processes and may adversely affect us as described below and in other ways 
we cannot currently predict. 

In  particular,  regarding  changes  to  the  general  conditions  for  our  services,  in  2011  the  ARSESP 
altered  the  standard  contract  that  we  are  required  to  use  in  our  relationships  with  retail  costumers.  The 
ARSESP changed the rule regarding the collection of water and sewage tariff, requiring that collection be 
directed to the consumer of our services, rather than to the owner of the served property, as used to be the 
case.  We  estimate  that  this  change  will  affect  ongoing  legal  disputes,  particularly  those  regarding 
collection procedures, as well as business discussions in general. However, we are not currently able to 
predict the impact of this change on our business, as the change is still being implemented.  

Regarding  changes  to  the  communication  process  for  the  reporting  of  failures,  the  ARSESP  has 
modified the rules and standards for supervision and reporting of incidents.  We have implemented these 
requested  changes.  Currently.  part  of  the  reporting  of  incidents  occurs  online,  through  the  Incident 
Reporting System (“Sistema de Comunicação de Incidentes”) established by the ARSESP, implementing 
more transparency and control in our operations. 

We  are  attentive  to  these  regulatory  changes,  have  been  working  toward  meeting  the  ARSESP’s 
requirements  and  recommendations,  and  have  presented  technical,  legal  and  factual  reasons  for  any 
conduct  that the ARSESP may find irregular.  As a result we are subject to few regulatory infractions and 
to  limited  fines.  See  “Risk  Factors—Risks  Relating  to  Our  Business—We  cannot  anticipate  the  effects 
that  further  developments  of  the  Basic  Sanitation  Law  and  its  interpretation  will  have  on  the  basic 
sanitation industry in Brazil and on us”. 

Concessions 

Concessions  for  providing  water  and  sewage  services  are  formalized  by  agreements  executed 
between the state or municipality, as the case may be, and a concessionaire to which the performance of 
these services is granted in a given municipality or region.  Our concessions normally have a contractual 
term  of  up  to  30 years.   However,  our  concessions  in  general  can  be  revoked  at  any  time  if  certain 

59 

 
standards  of  quality  and  safety  are  not  met,  or  in  the  event  of  default  of  the  terms  of  the  concession 
agreement.  

A  municipality  that  chooses  to  assume  the  direct  control  of  its  water  and  sewage  services  must 
terminate  the  current  relationship  by  duly  compensating  the  service  provider.   Subsequently,  the 
municipality will be in charge of rendering services or of conducting a public bidding process to grant the 
concession to potential concessionaires, including agreements with public companies directly.  Although 
the Constitution of the State of São Paulo determines that the relevant municipality would have to pay us 
for  the  unamortized  book  value  of  the  assets  related  to  the  concession  and  assume  any  corresponding 
debt, with the exclusion of any amounts that have been paid to us by the municipality, upon termination 
or non-renewal of the concession, the payment for termination may not be effected immediately, and any 
termination  could  negatively  affect  our  cash  flows,  operating  results  and  financial  situation.   See 
“Item 3.D.  Risk  Factors—Risks  Relating  to  Our  Business—Municipalities  may,  under  certain 
circumstances,  terminate  our  concessions  before  their  expiration  and  the  indemnification  may  be 
inadequate to recover the full value of our investments.” 

The  Federal  Concessions  Law  No.  8,987/1995  and  the  State  Concessions  Law  No.  7,835/1992 
require  that  the  granting  of  a  concession  by  the  government  be  preceded  by  a  public  bidding  process.  
However,  the  Federal  Public  Bidding  Law  No.  8,666/1993,  which  establishes  the  rules  for  the  public 
bidding  process,  provides  that  a  public  bidding  process  can  be  waived  under  certain  circumstances, 
including in the case of services to be provided by a public entity created for such specific purpose on a 
date prior to the effectiveness of this law, provided that the contracted price is compatible with what is 
practiced in the market.  Furthermore, a provision of the Federal Public Bidding Law, as amended by the 
Public Consortia and Cooperation Agreement Law, provides that the program contracted can be executed 
with waiver of a public bidding process.   

In the majority of municipalities where we operate, the new contracts have been formalized pursuant 
to the provisions of the Federal Public Bidding Law that allows the public bidding process to be waived 
under  certain  circumstances.   However,  due  to  the  discussion  over  whether  the  State  or  municipal 
authorities  have  the  right  to  grant  rights  to  provide  basic  sanitation  services  in  municipal  areas, 
negotiations of the terms of our new contract for the provision of water and sewage services in the city of 
São Paulo, were more complicated.  See “Related Party Transactions―Agreement with the State and the 
City of São Paulo”. 

On  June 18,  2009,  Municipal  Law  No.  14,934/2009  was  enacted  and  this  law  revoked  Law  No. 
13,670/2003, which had originally created the discussion on whether the State or the Municipality was the 
one with the powers to grant and monitor formal concessions for water and sewage services in the city of 
São  Paulo.  Although  the  new  law  authorized  the  city  of  São  Paulo  to  enter  into  an  agreement  with  us, 
because the issue of authority between the State or municipal government remain under judicial review, 
on  June 23,  2010, we  entered  into  a formal  agreement  with both  the  State  and  the  city of  São  Paulo  to 
regulate the provision of water and sewage services in the city of São Paulo for a 30-year period, which 
may be extended for an additional 30-year period.  

Public Consortia and Cooperation Agreement Law for Joint Management 

On  April  6,  2005,  the  federal  government  enacted  Federal  Law  No.  11,107,  or  the  Federal  Public 
Consortia  and  Cooperation  Agreement  Law,  which  regulates  Article 241  of  the  Brazilian  Constitution.  
This statute provides general principles to be observed when a public consortia enters 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. 

Federal Decree No. 6,017/2007 details the conditions of establishment of joint management and the 
execution of the program agreement regulating the Public Consortia and Cooperation Agreement Law.  
This federal legislation introduces significant changes in the relationship among municipalities, states and 
companies  providing  public  sanitation  services,  prohibiting  the  latter  from  exercising  activities  of 
planning,  oversight  and  regulation,  including  tariff  regulation,  of  the  services  and  creating  the  program 
agreement for contracting entities whose share control is held by one of the Brazilian political divisions 
and subdivisions upon waiver of the public bidding process and compliance with concession legislation, 
as applicable. 

60 

 
On  January  13,  2006,  the  Governor  of  the  State  of  São  Paulo  enacted  State  Decree  No.  50,470, 
amended by State Decrees No. 52,020, dated July 30, 2007, and No. 53,192, dated July 1, 2008, which 
provide  for  the  rendering  of  water  and  sewage  services  in  the  State  of  São  Paulo.   According  to  these 
decrees, we may enter into agreements with municipalities in connection with the provision of water and 
sewage  services  by  means  of  the  so-called  “program  agreement  without  a  public  bidding  process”.   In 
addition,  these  decrees  establish  that  we  will  continue  to  render  services  in  the  areas  covered  by  the 
concession granted by the State.   

Based  on  these  statutes,  in  January 2007  we  executed  our  first  program  agreement  with  the 
municipality  of  Lins,  located  in  the  State  of  São  Paulo.   Subsequently,  we  formalized  agreements  with 
other municipalities in the State of São Paulo.  These other municipalities transferred the oversight and 
regulation of our services to the State of São Paulo through a cooperation agreement.   

On June 8, 2006, the State of São Paulo enacted Decree No. 50,868 creating the Commission for the 
Regulation  of  Sanitation  Service  of  the  State  of  São  Paulo  (Comissão  de  Regulação  do  Serviço  de 
Saneamento do Estado de São Paulo – CORSANPA) to regulate sanitation services.  The Commission for 
the  Regulation  of  Sanitation  Service  of  the  State  of  São  Paulo  is  directly  subordinated  to  the  State 
Secretariat for Sanitation and Water Resources. 

The main duty of the Commission for the Regulation of Sanitation Service of the State of São Paulo 
was  conducting  studies for  the  creation of a  regulatory  agency for  the basic  sanitation  industry  and  the 
presentation of legal and regulatory measures.  The completion of such duties resulted in the publication 
of  supplementary  Law  No.  1,025  of  December 7,  2007,  which  created  the  ARSESP.  Furthermore, 
Supplementary  Law  No.  1,025/2007  maintained  the  State  Sanitation  Council  (Conselho  Estadual  de 
Saneamento – CONESAN), created by Supplementary Law No. 7,750/92, as an advisory council to define 
and  implement  the  state  basic  sanitation  policy,  and  the  State  Sanitation  Fund  (Fundo  Estadual  de 
Saneamento - FESAN).  The State Sanitation Fund is connected to the State Secretariat for Sanitation and 
Water Resources, and collects and manages resources that support State-approved programs, as well  as 
the development of technology, management and human resources and a sanitation information system, in 
addition to other support programs.   

The ARSESP regulates the basic sanitation services that belong to the State, relating to the federal 

and municipal jurisdictions and prerogatives, and is responsible for:   

 (cid:131)  the compliance with and enforcement of state and federal basic sanitation legislation; 

 (cid:131) the publication of the organizational platform for the services, indicating the types of services 

provided by the State, as well as the equipment and facilities that compose the system; 

 (cid:131) the acceptance, where applicable, of the legal attributions of the jurisdictional authority; 

 (cid:131) the establishment, in accordance with the tariff guidelines defined by Decree No. 41,446/96, of 
tariffs and other methods that provide compensation for our services, adjustment and review of 
such tariffs and methods to  ensure the financial-economic balance of services and low-cost tariffs 
through mechanisms that increase service efficiency and lead to the distribution of productivity 
gains to society; and 

 (cid:131) the approval, oversight and regulation (including tariff issues) of the sewage treatment and 

wholesale water supply agreements entered into between the state supplier and other suppliers, 
pursuant to Article 12 of the Basic Sanitation Law.

With respect to municipal basic sanitation, the ARSESP oversees and regulates services (including 
tariff issues) that have been delegated by municipalities to the State as a result of cooperation agreements, 
that authorize program agreements between the municipalities and us for as long as it is convenient to the 
municipality’s public interest.  

For  its  services,  the  ARSESP  charges  0.50%  of  the  annual  total  invoice  from  sales  and  services 
(excluding  revenues  relating  to  the  construction  of  concession  infrastructure)  of  the  municipality.   This 

61 

 
  
      
      
      
      
      
        
fee is collected from municipalities that have a signed program agreement with us and the municipalities 
located in the metropolitan regions.   

In  connection  with  the  scope  of  our  services,  Supplementary  Law  No.  1,025/2007  expanded  the 
range  of  services  that  we  can  render,  with  the  inclusion  of  urban  rainwater  drainage  and  management, 
urban  cleaning  and  solid  waste  management,  as  well  as  the  operation  of  power  generation,  storage, 
conservation and sales activities, for our own or third-party use. 

In addition, the rules simplified the process for the expansion of our business in Brazil and abroad, 

authorizing us: 

(cid:131)  to participate in the controlling block or the capital of other companies;

(cid:131) to create subsidiaries, which may become majority or minority shareholders in other companies; 

and 

(cid:131) to establish partnerships with national or foreign companies, including other state or municipal 
basic sanitation companies in order to expand our activities, share technology and expand 
investments related to basic sanitation services.

Public-Private Partnerships 

The PPP is a form of agreement with the public administration used for the concession of services to 
private  enterprises,  as  well  as  for  construction  works  coupled  with  the  provision  of  services.   PPPs  are 
regulated by the State of São Paulo through Law No. 11,688, which was enacted on May 19, 2004.  PPPs 
may  be  used  for:   (i)  implantation,  expansion,  improvement,  reform,  maintenance,  or  management  of 
public  infrastructure;  (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) tariffs paid by 
users; (ii) use of resources from budget; (iii) assignment of credits belonging to the State; (iv) transfer of 
rights related to the commercial exploitation of public assets; (v) paper of assets; (vi) paper from public 
debts; and (vii) other revenues. 

In our case, payment is conditional upon performance and is collected through the use of resources 

from the budget. 

Public Financing 

In January 2007, the President of Brazil announced a new Growth Acceleration Plan, known as the 
“PAC”, which includes major investments in infrastructure services, including the provision of water and 
sewage,  housing,  as  well  as  highways,  airports,  ports  and  energy  services,  that  would  benefit  the  poor 
population  of  Brazil.   PAC  calls  for  a  total  investment  of  R$504.0  billion  through  2010,  including  a 
R$40.0 billion investment in the sanitation sector.  The majority of the investment of the PAC would be 
provided by State-owned companies and the private sector, while the rest would come from the federal 
government.  Of the amounts dedicated to the sanitation sector, we have obtained various loans from the 
BNDES  and  Caixa  Econômica  Federal  totaling  R$2.8  billion,  the  proceeds  of  which  are  being  used  to 
fund  various  projects.   See  “Item  5.  Operating  and  Financial  Review  and  Prospects—Liquidity  and 
Capital Resources—Indebtedness Financing.” 

Public Bidding Procedures 

Pursuant to the Federal Public Bidding Law, the public bid process commences with publication by 
the granting authority in a federal, state or municipal official newspaper, as the case may be, and another 
leading  Brazilian  newspaper.   The  publication  announces  that  the  granting  authority  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:  (i) the purpose, duration and goals of the bid; (ii) the participation 
of bidders, either individually or forming a consortium; (iii) a description of the qualifications required 
for adequate performance of the services covered by the bid; (iv) the deadlines for the submission of the 

62 

 
  
      
      
    
   
bids; (v) the criteria used for the selection of the winning bidder; and (vi) 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: 

(cid:131) 

the technical quality of the proposal;  

(cid:131) lowest cost or lowest public service tariff offered;  

(cid:131) a combination of the criteria above; or  

(cid:131) the largest amount offered in consideration for the concession. 

The  provisions  of  State  Law  No.  6,544  of  November 2,  1989,  as  amended,  or  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  our  business 
operations  or  in  connection  with  our  capital  expenditure  program,  in  each  case  subject  to  certain 
exceptions. 

Water Usage  

State  law  establishes  the  basic  principles  governing  the  use  of  water  resources  in  the  State  of  São 

Paulo in accordance with the State constitution.  These principles include: 

(cid:131)  rational utilization of water resources, ensuring that its primary use is to supply water to the 

population;  

(cid:131) optimizing the economic and social benefits resulting from the use of water resources;  

(cid:131) protection of water resources against actions which could compromise current and future use;  

(cid:131) defense against critical hydrological events which could cause risk to the health and safety of the 

population or economic and social losses;  

(cid:131) development of hydro-transportation for economic benefit;  

(cid:131) development of permanent programs of conservation and protection of underground water 

against pollution and excessive exploitation; and  

(cid:131) prevention of soil erosion in urban and rural areas, with a view to protecting against physical 

pollution and silting of water resources.

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.  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  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), 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, DAEE is the public authority responsible 
for granting such authorizations.  DAEE has, as its objectives, establishing (i) a policy for the use of water 

63 

 
 
  
 
  
 
  
  
   
 
  
 
  
  
  
  
  
  
  
  
  
  
  
resources with a view to developing the water business of the State, and (ii) plans, studies and projects 
related to the use of water resources, directly or by means of agreements with third parties.   

Our  main  operating  units  have  been  granted  water  usage  rights;  however,  we  also  have  several 
operating units where water grants are not fully in place.  To help obtain the remaining water grants, we 
have established a corporate program for the legalization and maintenance of grants. 

In  July 2000,  ANA  was  established  to  develop  the  National  System  for  Water  Resources 
Management.   According  to  existing  law,  the  hydrographic  basins  committees  are  authorized  to  charge 
users, such as us, for the abstraction of water from, or dumping of sewage into, water bodies controlled by 
these agencies.  Since 2003 and as of December 31, 2011, we have paid R$93.3 million to ANA and the 
State Secretariat for the Environment (Secretaria do Estado do Meio Ambiente), and these agencies have 
used these amounts to pay for expenses related to the National and the State Systems for the Management 
of Water Resources (Sistema Nacional e Sistema Estadual de Gerenciamento de Recursos Hídricos) and 
principally to sponsor studies, programs, projects and constructions provided for in the Water Basin Plan 
(Plano de Bacia).  Resources for these projects may be loaned or provided to governmental agencies and 
corporations, including us, for use in projects related to the conservation and recovery of water resources.  

State Law No. 12,183, which was enacted on December 29, 2005, established the basis for charging 
for the use of the water resources under the domain of the State of São Paulo.  To apply such charging, 
the  law  provides  for,  among  other  provisions,  the  formulation  of  criteria  by  the  basin  committees,  the 
creation  of  basin  agencies  and  the  organization  of  a  registered  list  of  water  resource  users.   The  basin 
committee’s proposals regarding the criteria to calculate the amounts to be charged at each basin must be 
approved by the State Water Resource Council, and formalized by a decree issued by the State Governor. 

Water Quality 

Administrative  Rule  No.  2,914/2011,  issued  by  the  Ministry  of  Health  of  the  federal  government, 
provides the standards for potable water for human consumption in Brazil.  This rule is similar to the U.S. 
Safe  Drinking  Water  Act  and  the  regulations  enacted  by  the  U.S.  Environmental  Protection  Agency, 
which  establishes  rules  for  sampling  and  limits  related  to  substances  that  are  potentially  hazardous  to 
human health. 

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

Decree No. 5,440/2005 provides that the quality of water must be disclosed to consumers.  We have 
been complying with this regulation by publishing the required information in monthly bills and annual 
reports delivered to all consumers that we serve. 

Environmental Regulation 

The implementation and operation of water and sewage systems are subject to strict federal, state and 
municipal  laws  and  regulations  on  environmental  and  water-resource  protection.   The  National 
Environmental Council (Conselho Nacional de Meio Ambiental), or the CONAMA, is the federal agency 
responsible for the regulation of potentially polluting activities.  In the State of São Paulo, the Companhia 
Ambiental do Estado de São Paulo, or CETESB, is the governmental entity responsible for the control, 
supervision, monitoring and licensing of polluting activities, pursuant to State Law No. 997 of 1976 and 
State Law No. 13,542 of 2009.  The CETESB regulates the control of environmental pollutants. 

The control and environmental planning instruments are defined by several legal instruments, such as 
State Law No. 997/1976, which regulates the environmental pollution control; the CONAMA Resolution 
No.  05/1988,  which  requires  licensing  of  sanitation  projects  that  cause  significant  alterations  to  the 
environment; the CONAMA Resolution No. 237/1997, which regulates (i) environmental licenses, (ii) the 
federal,  state  and  local  jurisdiction  over  environmental  issues,  (iii)  the  list  of  activities  subject  to 
licensing; and (iv) environmental impact studies and reports; State Decree No. 47,400/2002 and related 
articles  from  State  Law  No.  9,509/1997  regarding  environmental  licensing;  and  State  Decree  No. 
8,468/76,  the  CONAMA  Resolution  No.  357/2005,  the  CONAMA  Resolution  No.  397/08  and  the 
CONAMA  Resolution  No.  430/11  and  the  granting  of  rights  for  using  and  interfering  with  water 
resources  (Portaria  Departamento  de  Águas  e  Energia  Elétrica  717/96).   Projects  with  significant 
environmental  impact  are  subject  to  specific  studies  prepared  by  multidisciplinary  teams  that  present  a 

64 

 
series  of  recommendations  focused  on  minimizing  the  environmental  impact.   These  studies  are  then 
submitted for analysis and approval by the government authorities.  The licensing process is composed of 
three stages, including the following licenses:   

(cid:131)   preliminary license – granted in the planning stage, approving the location and concept and 

attesting to the project’s environmental feasibility;

(cid:131) installation license – authorizing the beginning of works for the installation of the project, subject 

to compliance with approved plans, programs and projects, including environmental control 
measures and other necessary technical requirements; and

(cid:131) operation license – authorizing the operation of a unit or activity, subject to compliance with the 

technical requirements contained in the installation license.

We  have  established  a  program  (Programa  Corporativo  de  Manutenção  e  Regularização  de 
Licenciamento  Ambiental)  to  obtain  all  necessary  licenses  in  an  effort  to  bring  us  into  full  compliance 
with  environmental  regulations  within  five  years.   As  of  the  date  of  this  annual  report,  we  were  not  in 
possession of all licenses required in connection with our operations. Our failure to obtain such licenses 
may  result  in  the  imposition  of  fines  and  penalties.   With  respect  to  new  operations,  feasibility  and 
environmental compliance are carried out throughout the project. 

Sewage Requirements 

State  law  sets  forth  regulations  regarding  pollution  control  and  environmental  preservation  in  the 
State of São Paulo.  State law establishes the conditions and limitations for waste discharge that impacts 
water, air and soil.  According to this law, in areas in which there is 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  the 
standards and conditions established by the applicable environmental law, which allows such effluents to 
be treated by our treatment facilities and discharged in an environmentally safe manner.  Effluents that do 
not comply with such criteria are prohibited from being discharged into the public sewage system.  State 
legislation  also  establishes  that  liquid  effluents,  except  those  related  to basic  sanitation,  be subjected  to 
pre-treatment  so  that  they  meet  the  required  mandatory  levels  before  being  discharged  into  the  public 
sewage  system.   National  sanitation  guidelines  are  also  established  in  Article 45  of  Federal  Law  No. 
11,455/2007. 

The CETESB is authorized under State law to monitor discharges of pollutants into the environment 
and  to  enforce  the  requirements  of  State  law.   The  CETESB  is  responsible  for  issuing  preliminary 
installation and operation licenses granted to the pollution sources, including sewage treatment facilities. 

The CETESB also regulates the discharge of effluents into water bodies and must approve all of our 
treatment  facilities  in  accordance  with  federal  and  state  regulations.   State  and  federal  water  resource 
legislation  establish  the  charging  of  fees  for  the  discharge  of  treated  effluents  into  water  bodies.   This 
provision is already in force in relation to some water basins, and is in different stages of implementation 
in remaining basins.  See “—Government Regulation—Water Usage.” 

Governmental Restrictions on Incurrence of Debt 

On June 30, 1998, the CMN issued Resolution No. 2,515/98 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: 

(cid:131)   the proceeds of external credit operations must be exclusively used to refinance outstanding 

financial obligations of the borrower, 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

65 

 
  
      
      
     
     
(cid:131) the total amount of the contractual obligation must be subject to monthly deposits in a pledged 

account, equal to the total debt service obligation, including principal and interest, divided by the 
number of months that the obligation is to be outstanding.

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

Our  foreign  currency-denominated  transactions  are  also  subject  to  the  approval  of  the  National 
Secretariat  of  Treasury  (Secretaria  do  Tesouro  Nacional)  and  the  Central  Bank.   After  reviewing  the 
financial  terms  and  conditions  of  the  transaction,  the  National  Secretariat  of  Treasury  and  the  Central 
Bank 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. 

Lending Limits of Brazilian Financial Institutions 

The  CMN  Resolution  No.  2,827  of  March  30,  2001,  as  amended,  limits  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. 

Scope of Business 

State Law No. 12,292, dated of March 2, 2006, amended State Law No. 119, dated of June 29, 1973, 
which  created our  Company,  authorizes  us to  provide  water  and sewage  services  outside  São Paulo  (in 
other states of Brazil and other countries).  This law also authorizes us to own interests in other public or 
private-public companies and Brazilian or international consortiums.  In addition, this law permitted us to 
incorporate subsidiaries and enter into a partnership with or acquire interests in a private company with a 
corporate purpose related to the sanitation business. 

C.    Organizational structure 

Not applicable. 

D.    Property, Plant and Equipment 

Our  principal  property,  plant  and  equipment  comprise  administrative  facilities  which  are  stated  at 
historical  costs  less  depreciation.   The  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  are  recorded  as 
intangible assets (concession assets).  As of December 31, 2011, we operated through 66,389 kilometers 
of water pipes and mains and 45,073 kilometers of sewer lines.  As of that same date, we operated 212 
water  treatment  facilities  and  490  sewage  treatment  facilities,  as  well  as  16  water  quality  control 
laboratories.  

We  own our  headquarters  building  and  all  other  major  administrative  buildings.  We have  pledged 
some of our properties as collateral to the federal government in connection with a long-term financing 
transaction we have entered into with the IBRD that was guaranteed by the federal government.  We have 
also pledged part of our assets in the amount of R$249.0 million as collateral as of December 31, 2011, 
with respect to our indebtedness under the Special Program for Payment of Federal and Social Security 
Related  Taxes  in  Installments  (Programa  de  Parcelamento  Especial  para  Impostos  Federais  e 
Previdenciários), or PAES program.

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  consolidated  financial  statements  included  elsewhere  in 
this  annual report.   The  consolidated financial  statements  included  elsewhere  in  this  annual report  have 
been  prepared  in  compliance  with  IFRS  as  issued  by  the  IASB.   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.” 

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. 

A.    Operating and Financial Review and Prospects 

Overview 

As  of  December 31,  2011,  we  operated  water  and  sewage  systems  in  the  State  of  São  Paulo, 
including  in  the  city  of  São  Paulo,  Brazil’s  largest  city,  and  in  363  municipalities  in  the  State  of  São 
Paulo, which represented 56.3% of all municipalities in the State.  We also provided water services on a 
wholesale basis to six municipalities located in the São Paulo metropolitan region and to the municipality 
of Sumaré in which we did not operate water systems.  

The  São  Paulo  metropolitan  region,  which  includes  the  city  of  São  Paulo,  is  our  most  important 
service region.  With a total population of approximately 20.4 million, the São Paulo metropolitan region 
accounted for 75.6%, 74.5% and 73.9% of our gross revenue from sales and services in 2009, 2010 and 
2011 (excluding revenues relating to the construction of concession infrastructure), respectively.  60.6% 
of the concession intangible assets reflected on our balance sheet as of December 31, 2011 was 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 
concentrated 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  2008,  our  net  income  was  strongly  affected  by  the  global  financial  and  economic  crisis,  which 
began  in  2008  and  whose  effects  were  still  present  in  2009,  resulted  in  a  depreciation  of  the  Brazilian 
real   against the U.S. dollar, which adversely affected our obligations denominated in foreign currency. 

In  order  to  ensure  its  economic  and  financial  strength,  we  have  been  working  on  increasing  our 
efficiency  and  productivity  gains.   For  this  reason,  we  have  attempted  to  reduce  costs.   In  2009,  we 
decreased  our  staff  by  9.3%  pursuant  to  an  Agreement  for  the  Adjustment  of  Conduct  (Termo  de 
Ajustamento  de  Conduta),  or  TAC,  with  the  State  Public  Attorney’s  Office  (Ministério  Público 
Estadual).  Pursuant to the TAC, we laid off retirees who were still working for us and laid off employees 
representing approximately 2% of our workforce.  Our results of operations for the 2009, 2010 and 2011 
fiscal years were also affected by a provision for severance payments in the amount of R$146.6 million 
for  employees  who  resigned  in  2009,  R$19.0  million  for  employees  who  resigned  in  2010  and  R$47.0 
million for employees who resigned in 2011.  

67 

 
In 2011, our costs and expenses increased 15.7% compared to a decrease of 25% in our net income.  
In 2011, the volume invoiced increased 3.1% compared to 2010. The other increases are mainly related to 
depreciation and amortization, wages, the agreement with São Paulo and credits write-off, which amount 
to R$216.2 million, R$405.5 million, R$166.4 million and R$112.1 million, respectively. 

Effects of Tariff Increases 

Our  results  of  operations  and  financial  condition  are  highly  dependent  upon  our  ability  to  increase 
tariffs for our water and sewage services.  Since the enactment of the Basic Sanitation Law in 2007, as a 
general  rule,  regulatory  agencies  will  be  responsible  for  setting,  adjusting  and  reviewing  tariffs,  taking 
into consideration, among other factors, the following: 

(cid:131)       political considerations arising from our status as a State-controlled company;   

(cid:131)       anti-inflation measures enacted by the federal government from time to time; and   

(cid:131)        when  necessary,  the  readjustment  to  maintain  the  original  balance  between  each  party’s 

obligation and economic gain (equilíbrio econômico-financeiro) under the agreement. 

Readjustment of our tariffs continues to be set annually and depend on the parameters established by 
the Basic Sanitation Law and the ARSESP.  The guidelines also establish procedural steps and the terms 
for annual adjustments.  The annual adjustments must be announced 30 days prior to the effective date of 
the new tariffs, which take effect in September and remain in place for a period of at least 12 months.  See 
“4.B. Business Overview—Tariffs.” 

The  following  table  sets  forth,  for  the  periods  indicated,  the  percentage  increase  of  our  tariffs,  as 

compared to three inflation indexes:

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  exchange  rate  fluctuations,  inflation 
rates and interest rate levels.  For example, the general performance of the Brazilian economy affects our 
cost of capital and inflation affects our costs and margins.  The Brazilian economic environment has been 
characterized by significant variations in economic growth rates. 

General Economic Conditions 

The year 2008 was characterized by the worsening of the global financial and economic crisis.  As a 
result, the real depreciated by 32.0% against the U.S. dollar in 2008.  Nonetheless, at December 31, 2008, 
Brazil  had  R$206.8 billion  in  currency  reserves  and  a  trade  surplus  of  R$24.8  billion.   The  average 
unemployment rate in Brazil’s principal metropolitan regions was 6.8% in 2009.  The crisis’ main effect 
on  the  Brazilian  economy  was  a  decline  in  expectations  for  economic  activity  in  2009  and,  to  a  lesser 
extent, in 2010.  The year of 2011 was marked by the economic crises in the Euro zone.  In Brazil, there 
was a depreciation of 12.6% of the Brazilian real against the US dollar and Brazilian GDP increased by 
2.7%. 

In  2009,  Brazilian  GDP  decreased  0.2%  in  comparison  with  2008.   Nonetheless,  at  that  same  year 
Brazil had US$239.1 billion in currency reserves and its trade surplus was US$25.3 billion.  The average 
unemployment rate in Brazil’s principal metropolitan regions remained stable at 6.8% in 2009.

In  2010,  Brazilian  GDP  increased  7.5%  in  comparison  with  2009.   At  that  same  year,  Brazil  had 
US$288.6 billion  in  currency  reserves  and  its  trade  surplus  was  US$20.3  billion.   The  average 
unemployment rate in Brazil’s principal metropolitan regions was 6.7% in 2010. 

In  2011,  Brazilian  GDP  increased  2.7%  in  comparison  with  2010.   At  that  same  year,  Brazil  had 
US$352 billion  in  currency  reserves  and  its  trade  surplus  was  US$29.8  billion.   The  average 
unemployment rate in Brazil’s principal metropolitan regions was 6% in 2011. 

Interest 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 the domestic capital and lending markets.  As a 
result, we may continue to require substantial amounts of foreign currency-denominated indebtedness in 
order to satisfy our liquidity and funding requirements, which may increase our exposure to exchange rate 
fluctuations, as discussed below. 

The  official  interest  rate  set  by  the  Central  Bank,  the  SELIC  overnight  rate,  was  13.66%  as  of 
December 31,  2008.   In  2009,  in  order  to  boost  the  economy,  the  Central  Bank  reduced  the  official 
interest rate significantly, reaching 8.65% as of December 31, 2009.  In 2010, the Central Bank increased 
interest rates, and the official interest rate, as defined by the SELIC overnight rate target, was 10.66% as 
of December 31, 2010.  As of December 31, 2011, the SELIC overnight rate, was 10.91%. 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  indebtedness,  which  are  determined  by  reference  to  the  daily  government 
reference interest rate (Taxa Referencial), or TR, plus an agreed margin.  We cannot assure you that our 
tariffs will be increased, in future periods, to offset, in full or in part, the effects of inflation.   

Currency Exchange Rates 

We  had  total  foreign  currency-denominated  indebtedness of  R$3,053.4  million  as  of  December 31, 
2011, of which R$189.4 million relates to our short-term foreign currency-denominated obligations.  In 
the event of 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  32.0%  devaluation  of  the  real in  2008  increased  our  financial  expenses 
and negatively affected our overall results of operations for the year.  In contrast, the 25.5% appreciation 
of the real against the U.S. dollar in 2009 led to a foreign exchange gain of R$528.4 million.  In 2010, the 
4.3% appreciation of the real against the U.S. dollar led to a foreign exchange gain of R$66.1 million.  In 
2011, the 12.6% depreciation of the real against the U.S. dollar led to a foreign exchange loss of R$382.3 
million.  

We manage our indebtedness portfolio closely to decrease the cost of servicing our indebtedness as a 
whole and our exposure to exchange rate fluctuations.  We do not speculate in foreign currencies, and we 
do not have any exposure to derivatives tied to foreign currencies. 

The following table shows the fluctuation of the real against the U.S. dollar, the period-end exchange 

rates and average exchange rates as of or for the periods indicated:

From  time  to  time,  we  may  enter  into  forward  exchange  transactions  to  mitigate  foreign  currency 
exposure.   In  addition,  we  have  monitored,  overseen  and  controlled  our  foreign  currency-denominated 
indebtedness,  taking  advantage  of  market  opportunities  to  improve  the  profile  of  our  indebtedness  and 
reduce our costs.  As of December 31, 2011, we had no outstanding forward exchange transactions. 

Effects of Climate Change (Drought and Intense Rainfalls)  

We operate in a region of Brazil that has been prone to droughts, although historically droughts have 
not impacted all of our water supply systems equally.  Brazil experienced a prolonged and severe drought 
during 2000 and 2001. As a result, from mid-June to mid-September of 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,  which  reduced  our  total  water  production  by  approximately 
8%.  From April 2001 through January 2002 and from October to December 2003, we also rationed water 
in certain regions of the São Paulo metropolitan region, but on a much smaller scale.  This rationing on a 
smaller scale caused our total water production volume to be reduced by only 0.8%.  The effects of the 
drought continued to affect our systems through 2004.  Due to the water usage reduction bonus program 
that  we  operated  from  March  to  September 2004,  when  rainfall  was  extremely  low  and  our  reservoirs 
were at correspondingly low levels, and the return to normal rainfall levels that occurred throughout 2004 
and  early  2005,  the  conditions  of  our  reservoirs  improved  in  2005.   In  2006,  rainfall  was  sufficient  to 
enable us to maintain our reservoirs at levels reflecting the historic average.  In 2007 and 2008, rainfall 
exceeded the levels of previous years, increasing the volume of water held in our reservoirs and thereby 
providing a cushion to meet demand.  In 2009, rainfall levels were higher than the historic average and by 
the end of 2009, our reservoirs had a utilization rate of 87.0%, compared to a 50.0% and 41.0% utilization 
as  of  December 31,  2008  and  2007,  respectively.   In  2011,  rainfall  levels  were  slightly  lower  than 
historical averages and occurred during unusual times of year.  As of December 31, 2011, our reservoirs 
had a utilization rate of 62.8%, compared to a 74.4% utilization as of December 31, 2010. 

Critical Accounting Estimates and Assumptions 

We make estimates and assumptions concerning the future.  The resulting accounting estimates will, 
by  definition,  seldom  equal  the  related  actual  results.   The  estimates  and  assumptions  that  have  a 
significant risk of causing material adjustment to the carrying amount of our assets and liabilities within 
the next financial year are addressed below.   

Allowance for Doubtful Accounts 

We record an allowance for doubtful accounts in an amount that our management considers sufficient 
to  cover probable  losses, based  on  an  analysis  of  customer  accounts  receivable,  in  accordance  with  the 
accounting policy stated in Note 2.8 to our consolidated financial statements as of and for the years ended 
December 31, 2009, 2010 and 2011.  Provisions for the allowance for doubtful accounts are included in 
selling  expenses,  net  of  recoveries.   The  net  charge  to  this  allowance  was  R$117.4  million,  R$232.5 
million and R$120.4 million in 2009, 2010 and 2011, respectively. 

The methodology for determining the allowance for doubtful accounts 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 used are reasonable, actual results could differ from those estimates.  

Fair Value of Financial Instruments 

In  accordance  with  Brazilian  GAAP,  management  estimates  the  fair  value  of  financial  instruments 
using information available in the market and appropriate estimating methodologies.  Management uses 
considerable  personal  judgment  to  interpret  the  information  available  in  the  market  when  developing 
estimates  of  fair  value.   Therefore,  the  estimates  presented  may  not  necessarily  indicate  the  value  that 
would be obtained for the financial instruments if they were realized on the market. The use of different 
market  assumptions  and/or  estimating  methodologies  could  have  a  material  effect  on  the  estimated  fair 
values.

Indemnities Receivable 

Indemnities receivable is a long-term asset representing amounts receivable from the municipalities 
of Diadema and Mauá as indemnification for their unilateral termination of our water and sewage service 
concessions  in  1995.   As  of  each  of  December 31,  2009  and  2010,  this  asset  amounted  to  R$146.2 
million. In 2011, the Company decided to record a provision for losses related to the amount receivable 
from Mauá due to the uncertainty and recognized only the amount receivable from Diadema, since there 
is an ongoing negotiation. The amount receivable from Diadema amounted as of December 31, 2011, to 
R$60.3 million. 

Prior  to  their  termination,  pursuant  to  our  concession  contracts,  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  concessions  by  the  municipalities  of  Diadema  and  Mauá,  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 as long-term assets (indemnities receivable) and recorded impairment charges to 
reduce the carrying value of the assets to the estimated recoverable amounts which we had contractually 
agreed as fair compensation with these municipal authorities. 

Our rights to recover 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 those amounts, and we continue to monitor the status of the legal proceedings.  The ultimate 
amounts to be received however, if any, will most likely be subject to a final court decision.  Therefore, 
actual  amounts  received  could  differ  from  those  recorded.   For  more  information,  see  Note  9  to  our 
consolidated financial statements as of and for the years ended December 31, 2011, 2010 and 2009.  

Valuation of Long-Lived Assets 

As  of  December 31,  2011, we  had  property,  plant and  equipment  and  intangible  assets  of  R$356.5 

million and R$20,141.7 million, respectively.  

We  review  long-lived  assets,  primarily  buildings,  water  and  sewage  system  assets  and  concession 
intangible  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.   According  to  IFRS, 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 discounted 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. 

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 other factors.  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. 

Amortization of Intangible Assets 

Amortization is calculated when the intangible assets are available for use in the necessary condition 

established by the Company. 

Amortization  reflects  the  period  over  the  expected  future  economic  benefits  generated  by  the 
intangible asset and can be the period of the contract, depending on the contract.  The utilization of the 
assets  is  related  to  the  useful  life  of  the  assets  constructed  by  the  Company  and  amortization  of  the 
intangible assets is considered in the calculation of the tariff. 

71 

 
Amortization of the intangible assets finishes when the asset is totally consumed or is alienated, not 

being considered in the calculation of the tariff any longer, whichever occurs first. 

Depreciation of Property, Plant and Equipment 

Depreciation of our property, plant and equipment, primarily buildings, water and sewage service and 
other assets acquired, is provided using the straight-line method based on the estimated useful lives of the 
underlying assets.  While we believe that our estimates of current remaining estimated lives is reasonable, 
the  use  of  different  assumptions  and  estimates  and  changes  in  future  circumstances,  could  affect  the 
remaining useful lives of our asset, which could have a significant impact on our results of operations in 
the future. 

Provision for Contingencies 

tax  matters,  amounting 

As of December 31, 2011, we were party to judicial and administrative proceedings, relating to civil, 
environmental  and 
the  amount  of 
R$120.7 million  related  to  court  deposits)  with  respect  to  which  we  considered  the  risk  of  loss  as 
probable.  As of that date, proceedings with respect to which we considered the risk of loss as possible 
amounted to R$2,621.8 million, and those with respect to which we considered the risk of loss as remote 
amounted to R$19,958.3 million. 

to  R$1,571.8  million  (excluding 

We are a party to a number of legal proceedings involving significant monetary claims.  These legal 
proceedings  include,  among  other  types,  disputes  with  customers  and  suppliers  and  tax,  labor,  civil, 
environmental and other proceedings. For a more detailed discussion of these legal proceedings, see Note 
15 to our consolidated financial statements as of and for the years ended December 31, 2009, 2010 and 
2011.  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.  Therefore, 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 provisions for contingencies, actual losses realized in future periods could differ significantly from 
our estimates and could exceed the amounts which we have provisioned. 

Pension Plans 

The present value of the pension obligations depend on a number of factors that are determined on an 
actuarial  basis  using  a  number  of  assumptions.   The  assumptions  used  in  determining  the  net  cost 
(income)  for  pensions  include  the  discount  rate.   Any  changes  in  these  assumptions  will  impact  the 
carrying amount of pension obligations.   

We determine  the  appropriate  discount  rates  at  the  end  of each  year,  which  is the  interest  rate  that 
should be used to determine the present value of estimated future cash outflows expected to be required to 
settle the pension obligations. 

Other  key  assumptions  for  pension  obligations  are  based  in  part  on  current  market  conditions. 

 Additional information on the pension plans under Plan G0 and G1 is disclosed in Note 16. 

Differences  in  actual  experience  or  changes  in  assumptions  could  affect  the  carrying  amount  of 

pension obligations and expenses recognized in our results. 

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 State-owned companies which merged to form 
our Company.  These amounts must be reimbursed to us by the State, as primary obligor. 

In November 2008, we entered into the third amendment to the agreement with the State relating to 
payments  of  pension  benefits  made  by  us  on  its  behalf.   The  State  acknowledged  that  it  owed  us  an 
outstanding  balance  of  R$915.3  million  as  of  September 30,  2008,  relating  to  payments  of  pension 
benefits made by us on its behalf.  We provisionally accepted, but it is not recognized in our books, the 
reservoirs in the Alto Tietê System as partial payment in the amount of R$696.3 million, subject to the 

72 

 
transfer of the property rights of these reservoirs to us.  Since November 2008, the State has been paying 
the  remaining  balance  in  the  amount  of  R$219.0  million  in  114  successive  monthly  installments.   See 
Note 8 to our consolidated financial statements as of and for the years ended December 31, 2009, 2010 
and 2011 and “Item 7. Major Shareholders and Related Party Transactions.”  

Accounts Receivable from the State for Water and Sewage Services Rendered 

Certain  of  these  accounts  receivable  have  been  overdue  for  a  long  period,  and  we  do  not  reserve 
against such accounts receivable as we fully expect to recover these amounts and loss is not considered 
probable.  We have entered into agreements with the State with respect to these accounts receivable.  For 
further information on these agreements, see Note 8 to our consolidated financial statements as of and for 
the years ended December 31, 2009, 2010 and 2011 and “Item 7. Major Shareholders and Related Party 
Transactions.” 

Use of Certain Assets Owned by the State 

We  currently  use  certain  reservoirs  in  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 for use of the Billings and Guarapiranga reservoirs is provided for through a grant 
issued  by  the  DAEE.   We  have  a  right  to  use  these  reservoirs  so  long  as  we  remain  responsible  for 
maintaining and meeting their operating costs.

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010 

Net Revenue from Sales and Services 

Net revenue from sales and services increased by R$710.6 million, or 7.7%, to R$9,941.6 million in 
2011 from R$9,231.0 million in 2010.  This increase was principally due to the increase in tariff rates to 
6.83% in September 2011 from 4.05% in September 2010 and the 3.1% increase in sales volume. 

Cost of Sales and Services 

The cost of sales and services increased by R$836.6 million, or 16.1%, to R$6,031.1 million in 2011 
from R$5,194.5 million in 2010.  As a percentage of net revenue from sales and services, cost of sales and 
services increased to 60.7% in 2011 from 56.3% in 2010. 

73 

 
   
   
   
   
The increase in costs of sales and services was principally due to the following factors:  

(cid:131)   an increase of R$216.2 million, or 41.3%, as a result of our increased amortization expense 

related to our intangible assets for the services contract entered into with the municipality of São 
Paulo as well as to 99 expired or informal agreements, which are in the process of being 
formalized as program agreements. During 2011, we had a full year of the amortization of 
intangible assets related to the services contract entered into with the municipality of São Paulo in 
2010 and relating to those 99 expired or informal agreements. Under the aforementioned 
agreements, the related intangible assets generate greater amortization expense as they are 
amortized to zero (instead of a residual guaranteed amount reimbursed by the granting 
municipality at the end of the previous respective concession contracts). This increase is also due 
to the beginning of operations in 2011 of sites that had previously been under construction; 

(cid:131)   an increase of R$198.9 million, or 20.2%, in salaries and related charges as a result of: (i) the 

R$61.2 million adjustment in 2010 of actuarial calculation due to the migration of employees from 
defined benefit plan to defined contribution plan “SabesprevMais”; (ii) an increase of R$18.1 
million due to the payment of termination fees related to the terminated employees security fund 
(“Fundo de Garantia por Tempo de Serviço” or “FGTS”) incurred as a result of increased layoffs 
in 2011; (iii) 8% salary readjustments since May 2011, which had a total impact of R$81.3 
million; and (iv) the increase of R$21.6 million from the 2011 Cost of Sales and Services figure 
due to the higher expense relating to the profit sharing program as compared to 2010. 

 (cid:131) an increase of R$166.4 million, or 82.1%, in general expenses, mainly due to the R$158.8 million 
provision (corresponding to 7.5% of the gross revenue of capital after deduction of COFINS and 
PASEP) pursuant to the agreement with the municipality of São Paulo;

 (cid:131) an increase of R$65.1 million, or 10.8%, in costs of outsourced services, mainly due to (i) water 
and sewage systems maintenance, which amounted to R$16.9 million; (ii) the R$14.7 million 
increase in the Alto Tietê PPP designated amount for the contract’s second year, and the initiation 
of operations in September 2011; (iii) maintenance, in the amount of R$9.2 million, of water and 
sewer networks and connections in order to minimize losses and meet project deadlines set forth 
by the ARSESP; (iv) the transport of mud in the amount of R$7.1 million as a result of increased 
demand for water treatment, which causes increased quantities of mud to be transported; (v) an 
increase of R$6.3 million resulting from socio-environmental services established together with 
the municipality of São Paulo; (vi) R$4.4 million in costs related to mail and telegrams for the 
delivery of water bills in certain areas via post following judicial decisions; and (vii) vehicle 
rentals in the amount of R$2.8 million as part of the second phase of the renovation of our fleet.  
The increase in costs of outsourced services was partially offset by a decrease in telephone and 
data transmission charges in the amount of R$5.7 million, mainly due to the execution of a 
contract with Telecomunicações de São Paulo S.A. (“TELESP”), which involves landlines and 
long-distance data transfers as well as corporate cellular phones at lower costs to us. 

 (cid:131) an increase of R$53.9 million, or 10.2%, in the cost of electric energy due to the increase in 

consumption and higher energy tariffs.

 (cid:131) an increase of R$18.3 million, or 13.4%, in water-treatment products, mainly due to: (i) an 

increase of approximately 43% in the consumption of polyaluminium chloride, readjusted by 
approximately 11%.  This product was used principally in the Guaraú water treatment station in 
place of aluminum sulfate, guaranteeing maximum outflow without compromising the quality of 
the treated water.  This increase was partially offset on R$2.0 million by the decrease of the use of 
activated charcoal due to climate conditions, as well as due to the decelerated proliferation of 
algae in the reservoirs of the Alto Tietê System and Guarapiranga/Billings.

(cid:131) an increase of R$12.4 million, or 9.1%, in product-related expenses, mainly in connection with the 

maintenance of our water and sewer structure (in the amount of R$7.4 million) and with the 
increased expenses with fuel and lubricants for vehicles (in the amount of R$1.8 million), resulted

from an increase of 22% in the fuel price and from the expansion of our vehicle fleet. 

Gross Profit 

As  a  result  of  the  factors  discussed  above,  gross  profit  decreased  by  R$126.0  million,  or  3.1%,  to 
R$3,910.5 million in 2011 from R$4,036.5 million in 2010.  As a percentage of net revenue from sales 
and services, gross profit decreased to 39.3% in 2011 from 43.7% in 2010. 

Selling Expenses 

Selling expenses decreased by R$93.4 million, or 13.1%, to R$619.5 million in 2011 from R$712.9 
million in 2010.  As a percentage of net revenue from sales and services, selling expenses decreased to 
6.2% in 2011 from 7.7% in 2010. 

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

 (cid:131)   a decrease of R$112.1 million, or 48.2%, in credit write-offs, mainly as a result of additional 
provisions established in 2010 of R$34.2 million related to private clients and R$139.1 million 
related to public municipal entities (R$54.8 million of which related to the municipality of São 
Paulo); 

 (cid:131) a decrease of R$14.1 million, or 6.5%, in expenses with outsourced services mainly related to the 

agreement with municipality of São Paulo and the R$34.4 million decrease in the provision 
established in 2011 for new services to be provided under that agreement, and a R$4.9 million 
increase resulting from services provided to satisfy the schedule for implementing the Rationed 
Water Use Program (“Programa de Uso Racional da Água” or “PURA”) in city schools.  This 
decrease was partially offset by the following increases: (i) R$11.1 million in billing services, 
mainly resulting from new billing technology related to the reading of usage, issuance of bills and 
delivering bills, in addition to an increase in the number of connections and adjustments of  the 
contracts in the metropolitan region of São Paulo; and (ii) expenses in the amount of R$3.3 
million relating to services for the collection of credits.

 (cid:131) an increase of R$19.1 million, or 10.4 %, in the personel salaries and related charges as a result of: 

(i) the R$ 9.3 million adjustment in 2010 of the actuarial calculation  due to the migration of 
employees from defined benefit plan to defined contribution plan "Sabesprev Mais"; (ii) a R$ 1.4 
million increase due to the payment of termination fees related to the terminated employees 
security fund ("Fundo de Garantia por Tempo de Serviço") incurred as a result of increased 
layoffs in 2011; (iii) 8% salary readjustments since may 2011, which had a total impact of R$ 3.9 
million. 

 (cid:131) an increase of R$9.1 million, or 13.0%, in general expenses, mainly due to (i) water bills for 
banking institutions in the amount of R$4.2 million; and (ii) the R$3.3 million increase in tax 
provisions relating to the services rendered in the cities of São José dos Campos, 
Pindamonhangaba and Botucatu, resulting from increased collection during 2011 as compared to 
2010; 

 (cid:131) an increase of R$3.5 million, or 89.6%, in depreciation and amortization expenses, mainly due to 
the adjustment in amortization of intangible assets in connection with the agreement with the 
municipality of São Paulo. 

Administrative Expenses 

Administrative expenses increased by R$193.4 million, or 29.6%, to R$846.6 million in 2011 from 
R$653.2  million  in  2010.   As  a  percentage  of  net  revenue  from  sales  and  services,  administrative 
expenses increased to 8.5% in 2011 from 7.1% in 2010. 

The increase in administrative expenses was primarily due to: 

75 

 
    
  
      
      
     
     
     
   
 (cid:131)   an increase of R$187.4 million, or 79.6%, in salaries and related charges, mainly due to (i) the 
covering of actuarial liability in the amount of R$157.5 million related to the supplementary 
pension plan (plan G0) of the State of São Paulo (based on the non-recurring actuarial calculation 
performed on December 31, 2010); (ii) the cover of actuarial liability in the amount of R$22.2 
million related to the supplementary pension plan (plan G0) of the State of São Paulo for 2011; 
(iii) a R$3.0 million increase due to the payment of termination fees related to the terminated 
employees security fund (“Fundo de Garantia por Tempo de Serviço” or “FGTS”) incurred as a 
result of increased layoffs in 2011; and (iv) 8% salary readjustments since May 2011, which had 
the total impact of R$9.1 million;

 (cid:131) an increase of R$36.7 million, or 21.3%, in general expenses due to (i) the need for larger 
contingency provisions in the amount of R$59.7 million, particularly in connection with 
environmental issues in the municipalities of Guareí and Paraguaçu Paulista.  This increase was 
partially offset by the R$17.9 million provisioning made in 2010 for losses relating to third party 
claims; 

 (cid:131) a decrease of R$24.8 million, or 16.5%, in services provided by third parties in connection with a 
variety of matters, including: (i) a decrease of R$18.4 million in advertisement campaigns due to 
the termination of certain advertisement agreements; (ii) a R$5.5 million decrease due to 
reorganization and management performance related to the work of consultants and specialized 
service providers; 

(cid:131) a decrease of R$3.1 million, or 12.2%, in depreciation expenses due to the decreased immobilized 

assets of the controlling shareholder. 

Other Operating Income (Expenses), Net 

Other  operating  income  (expenses),  net  decreased  by  R$91.9  million  in  2011,  to  R$90.1  million 
expense  in  2011  from  R$1.8  million  income  in  2010.  This  increase  was  primarily  due  to  the  provision 
made  in  the  amount  of  R$85.9  million  related  to  assets  used  for  our  concession  in  the  municipality  of 
Mauá, and to the write-off of assets in the amount of R$35.3 million. 

Finance Cost, Net 

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

Finance cost, net increased by R$254.2 million, or 67.0%, to R$633.6 million in 2011 from R$379.4 
million in 2010.  As a percentage of net revenues from sales and services, finance cost, net increased to 
6.4% in 2011 from 4.1% in 2010.  

The increase was principally due to:  

 (cid:131)   an increase in foreign exchange loss related to loans and financing of R$448.5 million as a result 
of the 12.6% depreciation of the real against the U.S. dollar in 2011, compared to an appreciation 
of 4.3% of the real against the U.S. dollar in 2010;

 (cid:131) a decrease of R$46.0 million in monetary indexation, mainly due to (i) a higher expense in 2010 
amounting to R$20.0 million, due to the alteration of the unit price of our eleventh debentures 
issuance between their issuance date and their effective offering date in 2010; (ii) the depreciation 
of the real against the Japanese Yen upon the disbursement by Japan International Cooperation 
Agency (JICA) of R$14.0 million in 2011; and (iv) a decrease in the volume of refinancing of debt
in 2011 as compared to 2010, amounting to a decrease of R$12.0 million; and 

 (cid:131) other monetary revisions relating to our contracts in the amount of R$41.2 million.

The increase in finance cost, net was partially offset by: 

(cid:131) an  increase  of  R$153.5  million  in  interest  income  and  other  financial  income  due  to  the 

increase in our cash and cash equivalents; 

(cid:131) a decrease of R$95.5 million in financial expenses relating to judicial proceedings as a result 
of  the  lower  interest  income  regarding  the  proceedings  involving  clients  and  service 
providers in 2011; and 

(cid:131) a  decrease  of  R$33.6  million  in  interest  expenses  mainly  due  to  the  amortization  of  our 

eighth and ninth debentures in June and October 2011, respectively. 

Income before Income Taxes 

As  a  result  of  the  factors  discussed  above,  income  before  income  taxes  decreased  by  R$572.1 
million, or 24.9%, to R$1,720.7 million in 2011 from R$2,292.8 million in 2010.  As a percentage of net 
revenue from sales and services, our income before income taxes increased to 17.3% in 2011 from 24.8% 
in 2010. 

Income Taxes 

Income  taxes  decreased  by  R$165.0  million,  or  24.9%,  to  R$497.3  million  in  2011  from  R$662.3 

million in 2010.  The increase was primarily due to a decrease in taxable income in 2011. 

Net Income 

As a result of the factors discussed above, net income decreased to R$1,223.4 million in 2011 from 

R$1,630.5 million in 2010.  Net profit margin decreased to 12.3% in 2011 from 17.7% in 2010. 

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009 

Net Revenue from Sales and Services 

Net revenue from sales and services increased by R$651.5 million, or 7.6%, to R$9,231.0 million in 

2010 from R$8,579.5 million in 2009.   

Net revenue from sales and services relating to water services increased by R$125.4 million, or 3.3%, 

to R$3,942.9 million in 2010 from R$3,817.5 million in 2009.  This increase was principally due to: 

(cid:131) an average 3.8% increase in the volume of water invoiced 2010; and 

(cid:131) the effect of the 4.43% tariff increase in September 2009, and the 4.1% tariff increase in 

September 2010.

Net  revenue  from  sales  and  services  relating  to  sewage  services  increased  by  R$244.5  million,  or 
8.4%, to R$3,157.5 million in 2010 from R$2,913.0 million in 2009.  This increase was principally due 
to: 

(cid:131) an average 4.5% increase in the volume of sewage services invoiced in 2010; and  

(cid:131) the effects of the 4.43% tariff increase in September 2009 and the 4.1% tariff increase in 

September 2010.

Gross  revenue  from  construction  increased  by  R$90.9  million,  or  4.5%,  to  R$2,130.7  million  in 

2010 from R$2,039.8 million in 2009.

Cost of Sales and Services 

The cost of sales and services increased by R$107.2 million, or 2.1%, to R$5,194.5 million in 2010 
from R$5,087.3 million in 2009.  As a percentage of net revenue from sales and services, cost of sales and 
services decreased to 56.3% in 2010 from 59.3% in 2009. 

The increase in costs of sales and services was principally due to the following factors: 

(cid:131)   an increase of R$157.6 million, or 349.3%, in general costs on the provision of water and sewage 
services, of which R$167.2 million relates to a fee to the Fund of Environmental Sanitation and 
Infrastructure of the municipality of São Paulo which had to be paid according to the terms of the 
agreement with the State and the city of São Paulo executed on June 23, 2010.  This fee represents 
7.5% of the gross revenue of the São Paulo municipality as from the date of execution of the 
agreement; 

(cid:131) an increase of R$71.4 million in construction costs in 2010; 

(cid:131) an increase of R$51.2 million, or 9.3%, in outsourced services, mainly due to (i) the maintenance 
of water and sewage structure amounting to R$18.4 million, (ii) pavement and maintenance of 
side-walks amounting to R$14.2 million, and (iii) transportation of water and mud amounting to 
R$8.4 million; and 

(cid:131) an increase of R$45.8 million, or 9.5%, in the electricity expense mainly due to (i) an increase of 

5.2% in the electricity tariff, and (ii) an increase of 1.9% in the electricity consumption. 

The increase in costs of sales and services was partially offset by: 

(cid:131)   a decrease of R$196.8 million, or 16.7%, in salaries and related charges, mainly due to (i) a 

R$113.5 million decrease as a result of the reduction in our staff pursuant to the TAC, with the 
State Public Attorney’s Office (Ministério Público Estadual).  Pursuant to the TAC, we laid off 
retirees who were still working for us and laid off approximately 2% of our workforce; (ii) 
decrease in actuarial liability due to the migration from defined benefit plan to defined 
contribution plan amounting to R$79.3 million and (iii) a decrease of R$13.6 million related to 
adjustment in the profit sharing program for 2010;

(cid:131) a decrease of R$14.7 million, or 2.7%, in depreciation and amortization expenses. 

Gross Profit 

As a result of the factors discussed above, gross profit increased by R$544.3 million, or 15.6%, to 
R$4,036.5 million in 2010 from R$3,492.2 million in 2009.  As a percentage of net revenue from sales 
and services, gross profit increased to 43.7% in 2010 from 40.7% in 2009. 

Selling Expenses 

Selling expenses increased by R$102.5 million, or 16.8%, to R$712.9 million in 2010 from R$610.4 
million  in  2009.   As  a percentage  of net  revenue  from  sales  and  services,  selling  expenses  increased  to 
7.7% in 2010 from 7.1% in 2009. 

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

(cid:131)   an increase of R$115.1 million, or 98.1%, in the allowance for doubtful accounts related to 

municipal public entities; and 

(cid:131) an increase of R$11.8 million, or 5.8%, in outsourced services expenses, principally due to (i) a 
R$9.7 million provision related to future payment to the City Hall of São Paulo (Prefeitura 

78 

 
  
      
    
    
    
   
  
      
    
   
  
      
    
Municipal de São Paulo), or PMSP, pursuant to the agreement we entered into with PMSP on 
June 23, 2010; (ii) R$9.4 million in billing services, mainly related to an increase in network 
connections and the utilization of new technologies, which resulted in an increase in outsourcing 
expenses; and (iii) R$4.7 million related to increase in fraud control expenses. 

The  increase  in  selling  expenses  was  partially  offset  by  a  R$28.2  million,  or  13.3%,  decrease  in 
salaries and related charges in 2010, due mainly to:  (i) the reduction in our staff pursuant to the TAC, 
which resulted in a decrease of R$15.5 million in 2010; (ii) gain from the migration of employees from 
defined benefit plan to defined contribution plan “SabesprevMais” amounting to R$13.3 million; and (iii) 
R$13.8 million decrease resulting from the implementation of the PURA program. 

Administrative Expenses 

Administrative  expenses  decreased  by  R$63.9  million,  or  8.9%,  to  R$653.2  million  in  2010  from 
R$717.1 million  in  2009.   As  a  percentage  of  net  revenue  from  sales  and  services,  administrative 
expenses decreased to 7.1% in 2010 from 8.4% in 2009. 

The decrease in administrative expenses was primarily due to: 

(cid:131) 

(cid:131) 

(cid:131) 

a  decrease  of  R$96.8  million,  or  36.0%,  in  general  expenses  due  to  a  reduction  in 
contingency provisions mainly related to customer claims in 2010;   

a  decrease  of  R$11.5  million  in  termination  expenses  resulting  from  the  2009  staff 
reduction pursuant to the TAC; and   

a decrease of R$13.9 million in actuarial calculation due to the migration of employees 
from defined benefit plan to defined contribution plan “SabesprevMais.”   

The decrease in administrative expenses was partially offset by: 

(cid:131) 

(cid:131) 

an increase in actuarial liability related to the payment by us on behalf of the State of São 
Paulo of pension plan (plan G0) amounting to R$31.7 million due to a decrease in the 
discount rate from 6.6% to 6.0%;   

an  increase  of  R$19.2  million  related  to  the  deficit  in  defined  benefit  plan,  paid  to  the 
employees who migrated to the defined contribution plan “SabesprevMais.”   

Other Operating Income (Expenses), Net 

Other  operating  income  (expenses),  net  increased  to  R$1.8  million  income  in  2010  from  R$44.4 
million  expenses  in  2009.   The  increase  was  due  to  the  reclassification  of  the  expenses  related  to  the 
pension plan paid by us on behalf of the State of São Paulo (plan G0), which had been recorded as other 
operating expenses, net 2009, as administrative expenses in 2010. 

Finance Cost, Net 

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

Finance  cost,  net  increased  by  R$369.4  million,  or  3,694.0%,  to  R$379.4  million  in  2010  from 
R$10.0  million  in  2009.   As  a  percentage  of  net  revenues  from  sales  and  services,  finance  cost,  net 
increased to 4.1% in 2010 from 0.1% in 2009.  

The increase was principally due to: 

 (cid:131)   an increase in foreign exchange loss related to loans and financing of R$470.6 million as a result 
of the 4.3% appreciation of the real against the U.S. dollar in 2010, compared to an appreciation 
of 25.5% of the real against the U.S. dollar in 2009;

79 

 
   
  
      
 (cid:131) an increase in interest expenses of R$91.0 million due to the issuance of (i) our tenth, eleventh and 

twelfth debentures in November 2009, March 2010 and July 2010, respectively; (ii) our fifth 
promissory notes in August 2010; and

 (cid:131) an increase of R$85.9 million in expenses from monetary indexation resulting mainly from the 

increase in the IGP-M rate of 11.3% in 2010 compared to its decrease of 1.7% in 2009. 

The increase in finance cost, net was partially offset by: 

 (cid:131)   a decrease of R$158.7 million in expenses related to the adjustment for inflation of our provision 

for contingency due to a decrease in the inflation rate;

 (cid:131) an increase of R$65.2 million in financial income mainly due to (i) the renegotiation of debts with 
certain municipalities, mainly Taubaté and Ferraz de Vasconcelos, and (ii) the adjustment for 
inflation of court deposits; and 

 (cid:131) an increase of R$59.3 million in interest and other financial income due to the increase in cash and 

cash equivalents.

Income before Income Taxes 

As a result of the factors discussed above, income before income taxes increased by R$182.5 million, 
or 8.6%, to R$2,292.8 million in 2010 from R$2,110.3 million in 2009.  As a percentage of net revenue 
from sales and services, our income before income taxes increased to 24.8% in 2010 from 24.6% in 2009. 

Income Taxes 

Income  taxes  increased  by  R$59.7  million,  or  9.9%,  to  R$662.3  million  in  2010  from  R$602.6 
million  in  2009.   The  increase  was  primarily  due  to  the  increase  in  our  income  before  income  taxes  in 
2010. 

Net Income 

As  a  result  of  the  factors  discussed  above,  net  income  increased  by  R$122.8  million,  or  8.1%,  to 

R$1,630.5 million in 2010 from R$1,507.7 million in 2009. 

B.    Liquidity and Capital Resources 

Capital Sources 

In order to satisfy our liquidity and capital requirements, we have primarily relied on cash provided 
by  operating  activities,  borrowings  from  Brazilian  federal  and  state  governmental  financial  institutions, 
and financing from multilateral organizations and from domestic and international capital markets.  As of 
December 31,  2011,  we  had  R$2,150.0  million  of  cash  and  cash  equivalents.   Outstanding  short-term 
indebtedness  was  R$1,630.0  million  as  of  December 31,  2011,  of  which  R$189.4  million  was 
denominated  in  foreign  currency.   Long-term  indebtedness  was  R$6,966.3  million  as  of  December 31, 
2011,  of  which  R$2,864.0  million  consisted  of  foreign  currency-denominated  obligations.   We  believe 
that we have sufficient sources of liquidity and capital to meet our liquidity and capital requirements for 
the next few years, in light of our current financial position and our expected cash generated by operating 
activities. 

Cash Provided by Operating Activities 

Cash  provided  by  operating  activities  is  the  single  largest  source  of  our  liquidity  and  capital 
resources, and we anticipate that it will continue to be so in the future.  Our cash generated by operating 
activities  was  R$2,072.5 million,  R$2,083.0  million  and  R$2,717.1  million  in  2009,  2010  and  2011, 
respectively.

We  have  overdue  accounts  receivable  from  the  State  and  from  the  municipalities  to  which  we 

provide water on a wholesale basis.  For more information, see “Item 7.B. Related Party Transactions.” 

Indebtedness Financing 

Our total financial indebtedness increased by 4.0%, from R$8,264.6 million as of December 31, 2010 
to  R$8,596.3  million  as  of  December 31,  2011.   In  addition,  during  the  same  period,  our  total  foreign 
denominated indebtedness recorded increased 35.8%, from R$2,248.9 million as of December 31, 2010 to 
R$3,053.4 million as of December 31, 2011, mainly related to investments from the Japan International 
Cooperation Agency, or the JICA, amounting to 19,169.0 million Yens or R$ 375.9 million, which will 
be invested in the Metropolitan Coastal Region.  We also made significant amortization payments relating 
to certain Brazilian and foreign currency-denominated indebtedness.  

As  of  December 31,  2011,  we  had  R$6,966.3  million  in  long-term  indebtedness  outstanding 
(excluding  the  current  portion  of  long-term  indebtedness),  of  which  R$2,864.0  million  consisted  of 
foreign currency-denominated long-term debt.  We had outstanding short-term indebtedness of R$1,630.0 
million as of December 31, 2011, representing the current portion of our long-term indebtedness.  As of 
December 31,  2011,  R$189.4  million  of  this  short-term  indebtedness  was  denominated  in  foreign 
currency.  As of December 1, 2011, our Standard & Poor’s Rating Service domestic rating was braAA+ 
and our S&P international rating was BB+.   

Various  contractual  agreements  we  have  entered  into,  including  certain  financing  agreements  with 
Caixa  Econômica  Federal  and  the  BNDES,  provide  for  liens  over  a  portion  of  our  cash  flows  from 
operations.   In  addition  to  Caixa  Econômica  Federal  and  the  BNDES,  we  have  granted  liens  over  a 
portion  of  our  cash  flows  deriving  from  our  operations  in  connection  with  agreements  relating  to 
securitization  transactions,  the  Alto  Tietê  PPP  and  arrangements  relating  to  the  lease  of  certain  assets.  
Pursuant  to  these  agreements,  cash  received  from  operations  is  required  to  pass  through  designated 
accounts.  In the event of a default under the relevant agreement, such cash and future cash flows that are 
required to be deposited in such accounts become restricted and are subject to security interests in favor 
of the relevant creditor.  As of December 31, 2011, a substantial portion of our monthly cash flows from 
operations  was  subject  to  these  liens.   As  of  that  date,  the  total  amount  of  our  secured  debt,  including 
indebtedness benefiting from these liens, was R$2,546.9 million. 

The following table sets forth information on our indebtedness outstanding as of December 31, 2011:

Our  borrowings  from  multilateral  institutions,  such  as  the  IADB  and  IBRD,  have  in  the  past been, 
and in the future are likely to be, guaranteed by the State or the federal government.  We do not pay fees 
for these guarantees.  Under some of the loan agreements with the IADB, we have granted a guarantee 
(contra  garantia)  to  the  federal  government.  For  further  information  on  the  terms  of  these  loan 
agreements, see “Item 4.A. History and Development of the Company—Capital Expenditure Program—
Main  Projects  of  Our  Capital  Expenditure  Program—Metropolitan  System  Investment  Program—Tietê 
Project”; 

For further information on the terms and guarantees of the financing agreements with the JICA, see

and  Development  of  the  Company—Capital  Expenditure  Program—Main  Projects  of  Our  Capital 
Expenditure Program—Metropolitan System Investment Program—Clean Wave Program”.   

Our  outstanding  domestic  debt  was  R$5,542.9  million  as  of  December 31,  2011  and  consisted 
primarily of real-denominated loans from federal and state-owned banks, in particular, Banco do Brasil 
S.A.,  Caixa  Econômica  Federal  and  the  BNDES,  as  well  as  debentures  issued  in  November 2009, 
March 2010 September 2010, January 2011, February 2011, the first debentures issuance of our investee 
(Aquapolo) in August 2011 and financial leasing. 

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

(cid:131) in March 1994, we entered into a loan agreement with Banco do Brasil S.A., or Banco do Brasil, 

in the amount of R$2.3 billion.  Amortizations of the principal amount are made in 240 successive 

83 

 
    
    
  
      
monthly installments, with final maturity in 2014.  The principal amount accrues interest at the 
daily government interest rate plus 8.50% per annum and monetary adjustment; 

(cid:131) from 1996 to 2009, we have entered into several line of credit agreements with Caixa Econômica 
Federal, pursuant to which amortizations of principal are paid in 180 or 240 months in monthly 
installments commencing 30 days following the applicable grace period, which varies from 14 to 
48 months from the date of signature of the line of credit agreement.  The final maturity is 2032. 
 The principal amount accrues interest from 5.0% to 9.5%.  The lines of credit are collateralized 
by (i) collections of daily billings of water supply and sewage services up to the total amount of 
the debt, or (ii) by a monthly plan of billings corresponding to the minimum of three times the 
monthly charge, depending on the terms of the relevant line of credit agreement; 

(cid:131) in August 2002, we entered into a line of credit agreement with the BNDES.  The final maturity 
date is February 2013.  The principal amount accrues interest at the long-term rate fixed by the 
TJLP but limited to 6.0%, plus 3.0% per annum.  If the TJLP exceeds 6.0%, such excess will be 
added to the principal amount payable at maturity.  The line of credit agreement is collateralized 
by part of the billings from the provision of water and sewage services;

(cid:131)  in November 2007, we entered into a R$129.9 million credit agreement with the BNDES.  

Amortizations of the principal amount will be made in 96 successive monthly installments, with 
final maturity in 2019.  The principal amount accrues interest at the TJLP, but limited to 6.0%, 
plus 2.50% per annum.  If the TJLP exceeds 6.0%, such excess will be added to the principal 
amount.  The credit agreement is collateralized by part of the billings from the provision of water 
and sewage services; 

(cid:131)  in May 2008, we entered into a R$174.0 million financing agreement with the BNDES.  

Amortizations of the principal amount will be made in 150 successive monthly installments, with 
final maturity in 2023.  The principal amount accrues interest at the TJLP, but limited to 6.0%, 
plus 2.15% per annum.  If the TJLP exceeds 6.0% per annum, such excess will be added to the 
principal amount.  The financing agreement is collateralized by part of the billings from the 
provision of water and sewage services;

(cid:131)  in March 2010, we entered into a R$294.3 million financing agreement with the BNDES.  

Amortizations of the principal amount will be made in 156 successive monthly installments 
commencing 30 days after the 24-month grace period, with final maturity in 2025.  The principal 
amount accrues interest at the TJLP, but limited to 6.0%, plus 1.92% per annum.  If the TJLP 
exceeds 6.0%, such excess will be added to the principal amount.  The financing agreement is 
collateralized by part of the billings from the provision of water and sewage services; and 

(cid:131)  in 2011, we entered into financial leases in the total amount of  R$49.6 million with certain 

contractors for the construction of infrastructure on land we own. During the construction phase, 
we recognize an intangible assets and the related liability of the lease at fair value. Upon the 
conclusion of the construction, which is estimated to June 2013, we start to pay the rental of the 
infrastructure (in 192 installments) and the lease is updated accordingly to the contract. On 
December 31, 2011, there were no constructions completed. These contracts are recognized as 
financial leasing. 

Under the BNDES program, in the amount of R$826.1 million, we issued the first of three tranches 
of debentures.  In November 2009, we issued our tenth debentures in the aggregate principal amount of 
R$275.4  million.   The  debentures  are  divided  in  three  series:  the  first  and  second  series  will  mature  in 
November  2020  and  the  third  in  December  2020.   The  debentures  of  the  first  and  third  series,  in  the 
aggregate principal amount of R$77.1 million and R$115.7 million, respectively, bear interest at 1.92% 
per year, plus the TJLP.  If the TJLP exceeds 6.0%, such excess will be capitalized the 15th day of each 
month  that  such  debentures  are  outstanding.   The  debentures  of  the  second  series,  in  the  aggregate 
principal amount of R$82.6 million, bear interest at the rate of the IPCA index plus 9.53% per year.  Our 
tenth issuance was entirely subscribed by the BNDES.  We used the funds raised from this tenth issuance 
for investments primarily in the Corporate Program for Water Loss Reduction and on improvements and 
reforms of the Rio Grande’s water treatment plant, including other projects for water supply and sewage 
collection systems in the São Paulo Northern Coast, Paraíba Valley and Mantiqueira Regions.

In April 2010, we issued in two series our eleventh issuance of debentures in the aggregate principal 
amount  of  R$1,215.0  million.   The  first  and  second  series  will  mature  in  March 2015  and  2013, 
respectively.   The  debentures  of  the  first  series,  in  the  aggregate  principal  amount  of  R$810.0  million, 
bear interest at the CDI plus 1.95% per year, and the second series, in the aggregate principal amount of 
R$405.0  million,  bear  interest  at  the  CDI  plus  1.4%  per  year.   The  net  proceeds  from  our  eleventh 
issuance of debentures were partially used to redeem the promissory notes issued in December 2009.  The 
remaining portion was used for general corporate purposes. 

In  June  2010,  we  issued  500,000  debentures  to  the  Government  Severance  Indemnity  Fund  for 
Employees  (Fundo  de  Garantia  por  Tempo  de  Serviço),  or  FGTS,  based  on  the  FGTS’s  program  to 
finance  companies  in  the  sanitation,  transport  and  real  estate  businesses  (our  twelfth  issuance).   The 
proceeds will be released in three tranches within a six-month period each, totaling R$500.0 million in the 
aggregate, of which R$335 million was already released to us.  The debentures will bear interest based on 
the TR plus 9.5% per year.  The debentures will mature in June 2025.  The debentures have a grace period 
of four years in respect of payments, and we have an option to redeem the debentures as from July 2014. 
We  intend  to  use  the  proceeds  from  the  twelfth  issuance  to  fund  a  portion  of  our  capital  expenditure 
program in the water supply and sewage systems. 

In  January  2011,  we  issued  in  a  single  series  our  thirteenth  debentures  in  the  aggregate  principal 
amount  of  R$600.0  million.   The  debentures  will  mature  in  August 2012  and  bear  interest,  paid  semi-
annually,  at  the  CDI  rate  plus  0.65%  /  0.75%  /  0.85%  /  1.25%  per  year.   The  proceeds  were  used  to 
redeem the promissory notes issued in August 2010.  

On  February  15,  2011,  we  issued  100  debentures  subscribed  exclusively  by  the  National  Bank  for 
Economic and Social Development (BNDES). These debentures were distributed in three nonconvertible 
series, at a nominal value of R$ 2,753.70, totaling R$ 275.4 million. This transaction was settled on April 
15, 2011, for all series. The funds raised in this issuance will be used in expenditures in water supply and 
sewage systems in the following projects: Water Treatment Stations at Rio Grande, Litoral Norte, Vale do 
Paraíba and Mantiqueira, Bacia do Piracicaba-Capivari-Jundiai; and for program of reduction of losses. 
The debentures will mature in March 2022 and bear interest, paid monthly, quarterly and semi-annually, 
depending on the period, at the TJLP rate plus 1.92% per year or 9.19% per year. 

In August 2011, the joint-controlled entity “Aquapolo” issued 326,732 debentures, registered as its 
first issuance of simple debentures, nonconvertible, in a unique series amounting to R$326.7 million. The 
debentures will mature in August 2029 and bear interest, paid monthly, at the TR plus 8.75% per year. 

All  of  our  real-denominated  indebtedness  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 TR plus an agreed margin. 

In March 2011, our securitization fund (Fundo de Investimentos Creditórios) created in 2006 in the 
amount of R$250 million expired.  In addition, on June 1, 2011 the second series of our eighth issuance of 
debentures was paid in the amount of R$465.0 million. 

In  December 2010,  we  issued  US$350.0  million  aggregate  principal  amount  of  6.250%  senior 
unsecured notes due 2020.  Interest on the notes will accrue from December 16, 2010 at a rate of 6.250% 
per  year  and  will  be  payable  semi-annually  in  arrears  on  June 16  and  December 16,  commencing  on 
June 16,  2011.   The  notes  will  mature  on  December 16,  2020.   The  proceeds  from  the  offering  will  be 
used to repay financial commitments throughout 2011.  

In  February  2012,  we  issued  our  fifteenth  issuance  of  debentures  in  two  series  in  the  aggregate 
principal  amount  of  R$771.0.  The  first  and  second  series  will  mature  in  February  2017  and  2019, 
respectively.  The  debentures  of  the  first  series  (in  the  aggregate  principal  amount  of  R$287.3  million) 
bear interest at a rate of CDI plus 0.99% per year. The second series (in the aggregate principal amount 
R$483.7 million) bears interest at a rate of IPCA plus 6.2% per year. The net proceeds from out fifteenth 
issuance of debentures were used to repay financial commitments throughout 2012. 

Financial Covenants 

We are subject to financial covenants under the agreements evidencing or governing our outstanding 

indebtedness. 

85 

 
Foreign currency denominated indebtedness 

With respect to our indebtedness denominated in U.S. dollars or in baskets of foreign currencies, we 
are  subject  to  financial  covenants,  including  but  not  limited  to  those  set  forth  in  the  loan  agreements 
entered into with the IADB.  Each of these agreements contains, among other provisions, limitations on 
our ability to incur debt.  

The indenture relating to our US$140.0 million 7.5% notes due 2016 is the most stringent of these 
debt agreements. The indenture prohibits, subject to some exceptions, the incurrence of additional debt in 
the  event  that:  (i)  the  ratio  of  Adjusted  Total  Debt  to  Adjusted  EBITDA  (as  defined  in  the  related 
indenture) is greater than 3.65x; or (ii) the Debt Service Coverage Ratio (as defined in the indenture) is 
less than 2.35x. 

We do not believe that these covenants will impose constraints on our ability to finance our capital 
expenditure program or, more generally, to develop our business and enhance our financial performance. 

Local currency denominated indebtedness 

With  respect  to  our  outstanding  indebtedness  denominated  in  reais,  we  have  entered  into  several 

credit agreements with the BNDES that requires us to maintain the following ratios: 

Our  credit  agreements  with  the  BNDES  dated  August  2002  and  November  2007  require  us  to 
maintain:  (i)  an  EBITDA/net  operational  income  ratio  equal  to  or  higher  than  38%;  (ii)  an  asset/short-
term liability (excluding the short-term portion of long-term liabilities) ratio higher than 1.0x; (iii) total 
connections (water and sewage)/employees ratio equal to or higher than 520; (iv) EBITDA/debt service 
equal to or higher than 1.5x; and (v) a shareholders’ equity/total debt ratio equal to or higher than 0.8x. 

Our credit agreement with the BNDES dated May 2008 requires us to maintain: (i) an EBITDA/net 
operational  income  ratio  equal  to  or  higher  than  38%;  (ii)  an  EBITDA/financial  costs  ratio  equal  to  or 
higher than 2.35x; and (iii) a net bank debt/EBITDA equal to or higher than 3.2x. 

Our credit agreement with the BNDES dated March 2010 requires us to maintain: (i) an EBITDA/net 
operational  income  ratio  equal  to  or  higher  than  38%;  (ii)  an  EBITDA/financial  costs  ratio  equal  to  or 
higher than 2.35x; and (iii) net bank debt/EBITDA equal to or higher than 3.65%. 

In  addition,  our  BNDES  financings  have  the  following  financial  covenants:  (i)  EBITDA/net 
operational income ratio equal to or higher than 38%; and (ii) shareholders’ equity/total debt ratio equal 
to or higher than 0.8x. 

Pursuant to the terms of our credit agreements with the BNDES, the financial ratios mentioned above 

must be calculated based on our year end audited financial statements. 

Although we have been presenting our financial information in our annual reports on Form 20-F in 
compliance  with  IFRS  since  fiscal  year  ended  December  31,  2008,  our  Brazilian  financial  information 
was  presented  under  Brazilian  GAAP  for  fiscal  years  through  December  31,  2009.   Accordingly, 
compliance with the financial ratios mentioned above was calculated under Brazilian GAAP.  Brazilian 
Corporate  Law  was  recently  amended  to  facilitate  the  convergence  of  Brazilian  GAAP  with  IFRS,  and 
thereafter  the  Accounting  Pronouncement  Committee  (Comitê  de  Pronunciamentos  Contábeis)  issued 
several new accounting standards that progressively adapted Brazilian GAAP to IFRS (the new Brazilian 
GAAP).  Beginning with the fiscal year ended December 31, 2010, all Brazilian publicly held companies, 
such as us, must report under the new Brazilian GAAP.  Due to the impact of this change, we requested a 
temporary waiver from BNDES suspending compliance with these financial covenants in order to allow 
us to analyze the impact of the new Brazilian GAAP on our ability to comply with the financial ratios.  
BNDES granted the waiver on December 26, 2011, suspending compliance for 13 months beginning with 
December 2011. 

In  addition,  all  of  our  financing  agreements  with  the  Caixa  Econômica  Federal  and  most  of  our 
financing agreements with the BNDES are subject to a Performance Improvement Agreement (Acordo de 
Melhoria  de  Desempenho).   The  Performance  Improvement  Agreement,  dated  May  28,  2007,  as 
amended, was entered into between us and the Federal government, and the Caixa Econômica Federal and 
the BNDES as intervening parties.  Pursuant to this agreement, we must comply with eight financial and 
operating  ratios  during  the  next  five  years.   If  we  fail  to  comply  with  any  of  these  ratios,  the  Caixa 

86 

 
Econômica Federal and the BNDES may suspend our credit lines and we will be prevented from entering 
into any other financing agreements with those entities.  We have the ability, however, to renegotiate the 
ratios during the five-year period if needed.   

Our  financing  agreement  with  the  federal  government  and  Banco  do  Brasil  S.A.  and  our  credit 

agreements with Caixa Econômica Federal do not contain material financial covenants. 

With respect to our outstanding debentures, the eighth, ninth, eleventh and twelfth issuances require 
us  to  maintain  a  current  debt  ratio  (current  assets  divided  by  current  liabilities,  excluding  the  current 
portion of long-term indebtedness) higher than 1.0x and an EBITDA/financial expenditures ratio equal to 
or higher than 1.5x. 

The tenth issuance requires us to maintain (i) an EBITDA/net operational revenue ratio equal to or 
higher  than  38  percent;  (ii)  an  EBITDA/financial  expenditures  ratio  equal  to  or  higher  than  2.35x;  and 
(iii) a net bank debt/EBITDA ratio equal to or higher than 3.65x. 

The thirteenth issuance requires us to maintain (i) an EBITDA/financial expenditures ratio equal to or 

higher than 1.5% and (ii) a net debt/EBITDA ratio equal to or higher than 3.65%. 

As  of  the  date  of  this  annual  report  we  were  in  compliance  with  all  the  financial  ratios  that  are 

currently applicable to us.  

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, and dividend payments and other distributions to our shareholders, 
including the State. 

Capital Expenditures 

Historically,  we  have  funded  and  plan  to  continue  funding  our  capital  expenditures  with  funds 
generated  by  operations  and  with  long-term  financing  from  international  and  national  multilateral 
agencies  and  development  banks.   We  generally  include  in  our  capital  expenditure  program  for  the 
following year the amount of investment that was not realized in the previous year.  In 2011, we recorded 
R$2.4  billion  under  our  capital  expenditure  program.   We  have  budgeted  investments  in  the  amount  of 
approximately R$7.9 billion from 2012 through 2015.  

Dividend Distributions 

We are required by our bylaws to make dividend distributions, which can be made as payments of 
interest  on  shareholders’  equity  to  our  shareholders  in  an  amount  equal  to  or  higher  than  25%  of  the 
amounts available for distribution.  We made aggregate distributions of R$394.2 million, R$456.0 million 
and R$578.7 million in 2009, 2010 and 2011, respectively. 

On June 25, 2010, we paid R$198.1 million as dividends to the State.  See “Item 7.B. Related Party 

Transactions—Dividends.” 

Market Risk 

We are exposed to various market risks, in particular, foreign currency risk and interest rate risk.  We 
are  exposed  to  foreign  currency  risk  because  a  substantial  portion  of  our  financial  indebtedness  is 
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.   For  further  information  on  our  market  risks,  see  Note  3.1  to  our 
consolidated  financial  statements  as  of  and  for  the  years  ended  December 31,  2011,  2010  and  2009 
included elsewhere in this annual report.  

Exchange Rate Risk 

As  of  December 31,  2009,  2010  and  2011,  R$1,745.6  million,  R$2,248.9  million  and  R$3,053.4 
million, or 26.6%, 27.2% and 35.5%, respectively, of our debt obligations were denominated in foreign 

87 

 
   
currencies  (including  debt  pegged  to  baskets  of  foreign  currencies).   The  basket  of  foreign  currency-
pegged debt consists primarily of our debt with the IADB.  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. 

Exchange Rate Sensitivity 

We estimate that the potential loss to us in connection with U.S. dollar-denominated debt that would 
have  resulted  as  of  December 31,  2009,  2010  and  2011  from  each  hypothetical  instantaneous  and 
unfavorable  1%  change  in  the  U.S.  dollar  against  the  real    would  have  been  approximately  R$17.5 
million, R$22.5 million and R$30.5 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$174.6  million,  R$224.9 million  and  R$305.3  million  as  of  December 31,  2009,  2010 
and  2011,  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  fluctuation  of  the  real   in  relation  to  the  U.S.  dollar  and  with  the  IADB  and  IBRD  basket  of 

currencies, for the years ended December 31, 2009, 2010 and 2011 were as follows:

As of December 31, 2009, 2010 and 2011, we had no short-term indebtedness outstanding, other than 

the current portion of long-term debt. 

Interest Rate Risk 

As  of  December 31,  2009,  2010  and  2011,  R$2,193.1  million,  or  33.4%,  R$2,529.4  million,  or 
30.6%, and R$2,537.1 million or 29.5%, respectively, of our total debt outstanding balance denominated 
in  reais  was  based  on  variable  rates  of  interest  based  on  the  UPR,  which  is  equivalent  to  the  TR.   In 
addition, as of December 31, 2009, 2010 and 2011, R$1,132.4 million, or 17.3%, R$2,064.7 million, or 
25.0%, and R$1,882.3 million or 21.9%, respectively, of our total debt denominated in reais   was subject 
to interest rates based on the CDI.  As of December 31, 2009, 2010 and 2011, R$659.4 million, R$579.2 
million  and  R$747.3  million,  respectively,  of  our  foreign-currency  denominated  debt  was  based  on  the 
IADB and the IBRD variable rates of interest, which are determined based on the cost of funding of these 
multilateral organizations in each period. 

As  of  December 31,  2009,  2010  and  2011,  we  did  not  have  any  derivative  contracts  outstanding 
which  limited  exposure  to  changes  in  the  UPR  or  the  CDI  or  in  the  IADB  or  IBRD  variable  rates.  
However,  we  are  obliged  by  law  to  invest  our  excess  cash  with  financial  institutions  controlled  by  the 
Brazilian government.  We invest these excess funds, which totaled R$671.1 million, R$1,852.6 million 
and  R$2,027.0  million  as  of  December 31,  2009,  2010  and  2011,  respectively,  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 interest based on the CDI.  
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$65.6  million,  R$82.6  million  and  R$86.0  million  if  a  hypothetical  instantaneous  and  unfavorable 
change of 100 basis points in the interest rates applicable to financial liabilities as of December 31, 2009, 
2010 and 2011, respectively, had occurred.  Consistent with these estimates, a hypothetical instantaneous 
and  unfavorable  100  basis  points  change  in  these  interest  rates  would  have  resulted  in  losses  of 
approximately  R$655.8  million,  R$826.5  million  and  R$859.6  million  as  of  December 31,  2009,  2010 

88 

 
   
   
   
   
  
   
  
   
and 2011, 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 or nine months, as applicable, 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 (i.e., 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, 2011.  For 
the foreign currency denominated obligations, these amounts have been converted at the selling rates as 
of December 31, 2011 and do not represent amounts which may actually be payable with respect to such 
obligations on the dates indicated.

C.    Research and Development, Patents and Licenses, Etc. 

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 activity 
is divided into committees according to strategy and complexity.  In 2009, 2010 and 2011, we invested 
R$3.8 million, R$3.8 million and R$3.2 million, respectively, in research and development.   

In order to further develop our expansion plans, we created a new division for research, technology 
development and innovation in May 2010.  Among other initiatives, the new division is responsible for:  
monitoring  technological  trends,  defining  our  research  projects  portfolio,  obtaining  funding  from 
development agencies, developing an intellectual property protection policy and establishing cooperation 
agreements for the development of researches that are of our interest.  The new division will also enable 
us to increase the quality of our procedural processes and technology portfolio. 

With  respect  to  our  partnership  with  the  State  of  São  Paulo  Research  Foundation  (Fundação  de 
Amparo à Pesquisa do Estado de São Paulo), or the FAPESP, to develop and support research projects 
involving  researchers  from  graduate  schools,  the  State  of  São  Paulo  and  our  employees,  in  2010  we 
approved  12  projects  related  to:   (i)  the  development  of  technology  related  to  the  use  of  filtering 
membranes  in  water  and  sewage  treatment,  (ii)  alternatives  for  the  treatment,  mud  disposal  and  use  in 
water  and  sewage  treatment  stations,  (iii)  new  technologies  for  the  implementation,  operation  and 
maintenance of water distribution and sewage collection systems, (iv) new technologies for improvements 
in unitary operations processes, (v) water quality monitoring, (vi) energetics efficiency and (vii) sanitary 
economy.

a device for the removal of supernatants in the treatment of sewage; and   

a mobile device for the calibration of hydrometers. 

We  are  currently  awaiting  responses  to  our  patent  requests  from  the  INPI.   While  the  requests  are 

under consideration, we are granted the exclusive right to use these devices. 

Software  

We have adopted an internal policy that provides for an active and effective audit and prevention of 

unauthorized software.  We have acquired the software licenses for all our workstations. 

We  have  also  developed  certain  computer  programs  for  management  and  control  of  water  and 
sewage treatment facilities, as well as for third-party services management, called “AQUALOG (Control 
Water  Treatment  Plants),”  “SGL  (Bid  Management  System),  “SCORPION  (software  to  Operacional 
Control)”,  “Electronic  Price  Quotation”  (Cotação  Eletrônica  de  Preços),   “PREGÃO  SABESP 
ONLINE”,  “SISDOC  –  Sistema  de  Controle  de  Documentos”,  “Sistema  de  análise  do  comportamento 
metrológico de hidrômetros”, “Modelo padronizado de Laudo técnico-MPLT,” and "SGH" - hydrometry 
management  system  (Sistema  de  Gestão  de  Hidrometria).   We  have  also  secured  registration  of  these 
programs at the INPI. 

AQUALOG is a Brazilian software designed to monitor water treatment through the employment of 
artificial  intelligence.   In  2001,  we  completed  the  first  rendering  of  services  based  on  the  AQUALOG 
software to a third party with the automatization of a water treatment plant in the city of Jaguará do Sul, 
State of Santa Catarina.  We have entered into an agreement to license the software to Sanesul, in the state 
of Mato Grosso do Sul and to Teuto’s drugs factory, in the city of Anapólis, state of Goiás.  We currently 
have  a  temporary  license  for  the  AQUALOG  software  and  are  awaiting  its  final  registration  with  the 
INPI. 

SGL is an electronic price quotation system that allows us to view and control all bid and acquisition 

proceedings in real time.

We believe that we can meet the maturity schedule through a combination of funds generated by 
operations, the net proceeds of new issuances of debt securities in the Brazilian and international capital 
markets and additional borrowings from domestic and foreign lenders.  Our borrowings are not affected 
by seasonality.  For information concerning the interest rates on our indebtedness outstanding as of 
December 31, 2011, see Note 12 to our consolidated financial statements included elsewhere in this 
annual report.  
ITEM 6.        DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES 
A.    Directors and Senior Management 

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

As  our  controlling  shareholder,  the  State  has  the  ability  to  control  the  election  of  our  board  of 
directors and, therefore, our direction and future operations.  Upon the election of a new State governor 
and any resulting change in the administration of the State, all or some of the members of our board of 
directors,  including  our  chairman,  have  historically  been  replaced  by  designees  of  the  new 
administration.   Our  board  of  directors  may  in  turn  replace  some  or  all  of  the  executive  officers.   See 
“Item 3.D. Risk Factors—Risks Relating to Our Control by the State of São Paulo—We are controlled by 
the State of São Paulo, whose interests may differ from ours or from minority shareholders’ interests, and 
which could have a material adverse effect on us.” 

Board of Directors 

Our  bylaws  provide  for  a  minimum  of  five  and  a  maximum  of  15  directors.   The  members  of  our 
board  of  directors  are  elected  at  a  general  shareholders’  meeting  to  serve  renewable  two-year  terms. 
 Pursuant to our bylaws, our employees have the option to elect one member of our board of directors. 
 Currently, our employees have not elected a director.  In addition, pursuant to Brazilian Corporate Law, 
at least one member of the board of directors of mixed capital companies, such as us, must be appointed 
by the minority shareholders.  Finally, according to the Novo Mercado rules, at least 20.0% of the board 
of directors must be comprised of independent members. 

The current members of our board of directors were elected in the general shareholders’ meeting held 
on  April 23,  2012.   The  tenure  of  the  directors  will  end  upon  the  election  of  the  new  members  at  the 
general  shareholders’  meeting  to  be  held  in  April 2014.   Currently,  we  have  three  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 names, ages, positions, dates of election and brief biographical descriptions of 

the current members of our board of directors:

We  have  established  a  pension  and  benefit  fund  (Fundação  SABESP  de  Seguridade  Social),  or 
SABESPREV,  to  provide  our  employees  with  retirement  and  pension  benefits.   This  pension  plan 
provides  benefit  payments  to  former  employees  and  their  families.   Both  we  and  our  employees  make 
contributions to the pension plan.  We are also required to pay supplemental pension payments relating to 
the  employment  contract  of  certain  employees  prior  to  the  creation  of  SABESPREV.   Our  total 
contributions to the pension plan totaled R$12.9 million, R$13.8 million and R$8.9 million in 2009, 2010 
and 2011, respectively.  Based on independent actuarial reports, as of December 31, 2011, our obligation 
under these plans totaled R$1,638.2 million.  For further information on our pension plans see Note 16 to 
our consolidated financial statements.  

Beginning  in  2008,  payments  under  the  profit-sharing  plan  were  based  both  on  general  goals  that 
evaluate  us  as  a  whole  and  on  other  goals  that  evaluate  the  performance  our  different  business  units.  
Payments are proportionally reduced annually if the goals are not completely achieved. 

We recorded profit-sharing expenses of R$53.4 million, R$52.6 million and R$56.6 million in 2009, 

2010 and 2011, respectively.  We do not have a stock-option plan for our employees. 

C.    Board Practices 

The  members  of  our  board  of  directors  are  elected  at  a  general  shareholders’  meeting  to  serve 
renewable  two-year  terms.   Our  board  of  directors  ordinarily  meets  once  a  month  or  when  called  by  a 
majority of the directors or the chairman.  See “Item 6.A. Directors and Senior Management—Board of 
Directors.”   

Our  board  of  executive  officers  is  composed  of  six  executive  officers  appointed  by  our  board  of

extraordinary  meetings.   See  “Item 6.A.  Directors  and  Senior  Management—Board  of  Executive 
Officers.” 

None of  our  directors  and/or  executive officers  is  a party  to  an  employment  contract  providing for 
benefits upon termination of employment.  Those directors and officers who are also our employees will 
remain  as  our  employees  after  their  tenure  as  directors  and/or  officers,  in  this  case,  maintaining  all 
benefits granted to our employees.

D.    Employees  

As of December 31, 2011, we had 14,896 full-time employees.  In 2011, we had an average of 918 
trainees  and  506  apprentices  (aprendizes),  as  defined  by  federal  Law  No.  10,097,  dated  December  19, 
2000.

The average tenure of our employees is approximately 17 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 five main unions that represent 
our  employees  are  the Sindicato dos  Trabalhadores  em  Água,  Esgoto  e Meio  Ambiente  de  São  Paulo - 
SINTAEMA,  Sindicato  dos  Trabalhadores  da  Região  Urbana  de  Santos,  São  Vicente,  Santos,  Região 
Metropolitana de Santos, Litoral Sul e Vale Ribeira - SINTIUS, the Sindicato dos Engenheiros do Estado 
de São Paulo - SEESP, the Sindicato dos Advogados de São Paulo - SASP and the Sindicato dos Técnicos 
Industriais de Nível Médio(2ºGrau) no Estado de São Paulo - SINTEC. As a result of the 2010 collective 
bargaining  discussions,  wages  were  temporarily  increased  by  5.05%.  The  unions  filed  a  claim  with  the 
Labor  Court  seeking  to,  among  other  requests,  increase  wages  by  1.5%,  increase  the  salary  base  over 
which  the  annual  profit  distribution  is  calculated,  increase  payment  of  overtime  in  100%  and  increase 
additional payment of working night hours from 20% to 50%. The Labor Court decided in favor of the 
unions  and  we  appealed  from  the  decision.  We  are  still  waiting  for  the  decision  on  our  appeal.  Any 
unfavorable decision by the Labor Court will result in an increase in expenses with personnel. Our most 
recent  collective  bargaining  agreement,  entered  into  in  2011:  (i)  increased  wages  by  6.39%  (which 
corresponds to the adjustment for inflation for the period) plus a real gain of 1.51%, (ii) established an 
employment  guarantee  for  98%  of  our  employees,  (iii)  increased  the  number  of  days  permitted  under 
maternity  leave  from  120  to  180  days  and  (iv)  increased  meal  vouchers  by  10.07%,  among  other 
provisions. 

We  have  experienced  the  following  strikes  in  the  last seven  years,  none  of  which  interrupted  the 
essential services that we provide:  a two-day strike in June 2005, a one-day strike in May 2006, a four-
day strike in June 2008, a three-day strike in May 2009, an eight-day strike in May 2010 and a one day 
strike  in  2011.   Under  Brazilian  law,  our  non-administrative  employees  are  considered  “essential 
employees” and, therefore, are limited in their right to strike. 

E.    Share Ownership 

As  of  April  23,  2012,  the  members  of  the  board  of  directors  and  the  executive  officers  owned  an 
aggregate of 2,612 common shares.  The members of our board of directors and our executive officers, on 
an  individual  basis  and  as  a  group,  beneficially  own  less  than  0.1%  of  our  common  shares.   See 
“Item 7.A.  Major  Shareholder”  for  more  information.   As  of  the  same  date,  none  of  our  directors  and 
executive officers owned any stock option plans. 
ITEM 7.        MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS 
A.    Major Shareholder 

Our  outstanding  capital  stock  as  of  December 31,  2011,  consisted  of  227,836,623  common  shares, 
without par value.  Under our bylaws and the State laws, the State is required to own at least one-half plus 
one of our outstanding common shares.  All of our shareholders, including the State, have the same voting 
rights. 

The following  table  sets forth ownership  information  for  each  of our shareholders  that  beneficially

ownership of our ADSs, there were, on March 30, 2012, 38 record holders of ADSs in the United States. 

B.    Related Party Transactions 

Transactions with the State of São Paulo 

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 that 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.   Among  the  practices  that 
could change are those described below concerning the provision of State guarantees, and the terms on 
which we use State-owned reservoirs.  

Rending Services 

We provide water and sewage services to the federal government, 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  R$358.3 million  in  2009,  R$383.5  million  in  2010  and  R$405.0 
million  in  2011.   Our  accounts  receivable  from  the  State  for  water  supply  and  sewage  services  totaled 
R$169.5 million,  R$157.2  million  and  R$145.4  million,  as  of  December 31,  2009,  2010  and  2011, 
respectively.  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 
that provided services to us in the past and later merged to form our Company acquired a legal right to 
receive  supplemental  pension  benefit  payments.   These  rights  are  referred  to  as  “Plan  G0.”   These 
amounts are paid by us, on behalf of the State, and are claimed by us as reimbursements from the State, as 
primary obligor.  In 2009, 2010 and 2011, we made payments to former employees of R$108.0 million, 
R$118.4  million  and  R$124.4  million,  respectively,  in  respect  of  Plan  G0.   The  State  made 
reimbursements  in  2009,  2010  and  2011  in  the  amount  of  R$83.7 million,  R$59.0  million  and  R$60.4 
million, respectively.   

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.   

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

(cid:131)  water  and  sewage  services  we  provided  to  governmental  agencies,  State-owned 
autonomous entities and foundations through December 1, 2001, and that was not offset 

102 

 
   
   
   
in  accordance  with  the  September 1997  memorandum  of  understanding,  in  the  total 
amount  of  R$358.2 million.   This  amount  was  renegotiated  and  included  in  the  second 
amendment to this agreement discussed below; and 

(cid:131) 

to 
supplemental  retirement  and  pension  benefits  we  paid  from  March 1986 
November 2001  on  behalf  of  the  State  to  former  employees  of  the  State-owned 
companies  which  merged  to  form  our  Company;  as  we  did  not  reach  an  agreement 
regarding  these  amounts,  a  joint  inquiry  has  commenced  in  order  to  ensure  agreement 
between  us  and  the  State,  in  the  total  amount  of  R$320.6 million.   This  amount  was 
renegotiated and included in the third amendment to this agreement discussed below. 

The agreement provided that the DAEE would transfer to us ownership of the Taiaçupeba, Jundiaí, 
Biritiba, Paraitinga and Ponte Nova reservoirs (herein  after referred to as “the reservoirs”), which form 
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  2002,  a  State-owned  construction  company  (Companhia 
Paulista  de  Obras  e  Serviços),  or  the  CPOS,  on  behalf  of  the  State,  and  an  independent  appraisal  firm 
(Engenharia de Avaliações), or the ENGEVAL, on our behalf, presented their valuation reports relating 
to the reservoirs.  Under the agreement, the arithmetic average of these appraisals is deemed the fair value 
of the reservoirs.  The appraisals contained in these reports were in the amounts of R$335.8 million and 
R$341.2 million, respectively.  Because we had already made investments in these reservoirs by then, the 
arithmetic average of the appraisals submitted to our board of directors by August 2002, R$300.9 million, 
was  net  of  a  percentage  corresponding  to  these  investments.   Our  board  of  directors  approved  the 
valuation reports. 

Under the December 2001 agreement, for amounts due in excess of the fair value of the reservoirs, 
the State is to make payments in 114 consecutive monthly installments.  The nominal amount owed by 
the State would not be indexed to inflation or earn interest if there was a delay in concluding the appraisal 
of fair value.  The installments will be indexed on a monthly basis by the IGP-M index, plus 6.0% per 
year, starting on the date the first installment becomes due. 

On October 29, 2003, the Public Prosecution Office of the State of São Paulo (Ministério Público do 
Estado de São Paulo), on behalf of the people of the State, brought a civil public action in a Trial Court of 
the State of São Paulo (12a Vara da Fazenda Pública do Estado de São Paulo) alleging that a transfer to 
us  of  ownership  of  the  Alto  Tietê  system  reservoirs  from  the  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 of first instance handed down its judgment on the civil public action and declared 
the agreement between us, DAEE and State of São Paulo null and void.  This decision was suspended by 
us, and the State treasury and DAEE appealed the decision.  On August 23, 2010, the appeal was denied.  
We have petitioned  for  clarification of  the appeal  court’s decision  and will  seek  to  take  the  case  to the 
Supreme  Court.   The  effects of  the  appeal  court’s decision  will  be  suspended until  the  end of  the  legal 
process.  Our legal counsel has assessed the risk of loss as probable, which would prohibit the transfer of 
the reservoirs in payment of the accounts receivable due from the State. 

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.  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  are  formalized.   As  discussed  above,  the  transfer  of  these  reservoirs  is 
currently being disputed and we are not certain whether the transfer will be legally permitted.  Under the 
December 2001 agreement, the first payment was to be made in July 2002.   

On  March 22,  2004,  we  and  the  State  entered  into  a  first  amendment  to  the  December 2001 
agreement.  Under this amendment, the State acknowledged that it owed R$581.8 million to us relating to 
unpaid accounts receivable from the State until February 29, 2004, and we acknowledged that we owed 
an aggregate amount of R$518.7 million to the State as dividends, in the form of interest on shareholders’ 
equity.   Accordingly,  we  and  the  State  agreed  to  offset  each  other’s  credit  up  to  the  limit  of 
R$404.9 million,  which  was  an  amount  adjusted  up  to  February 2004.   The  outstanding  balance  of 
R$176.9 million (as of February 29, 2004) of the State’s consolidated debt would be paid in consecutive 

103 

 
   
monthly installments from May 2005 until April 2009.  These installments would be indexed according to 
the IPCA index, plus an interest rate of 0.5% per month.  Upon the execution of the first amendment, part 
of the debt that the State owed to us for the use of water and sewage services through February 2004 was 
offset by the debt that we owed to the State as dividends, in the form of interest on shareholders’ equity.  
The outstanding balance of R$113.8 million as dividends in the form of interest on shareholders’ equity 
that we owed to the State was netted against accounts overdue after February 2004.  The first amendment 
did not amend the provisions of the December 2001 agreement regarding the 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.  

On  December 28,  2007,  we  and  the  State  entered  into  a  second  amendment  to  the  December 2001 
agreement,  pursuant  to  which  the  State  agreed  to  pay  (i)  the  outstanding  balance  under  the  first 
amendment,  in  the  amount  of  R$133.7 million  (as  of  November 30,  2007),  in  60  consecutive  monthly 
installments, beginning on January 2, 2008, and (ii) the amount of R$236.1 million relating to part of the 
accounts  overdue  and  unpaid  from  March  2004  through October 2007  regarding  the provision of water 
supply and sewage collection services.  As part of this amendment, we agreed to pay during the period 
from  January  through  March  2008  the  outstanding  balance  of  dividends  in  the  amount  of  R$400.8 
million, in the form of interest on shareholders’ equity, due from March 2004 through December 2006.  
We paid these amounts as agreed.  Under the second amendment, dividends payable by us are no longer 
required to be applied to offset accounts receivable from the State, and as a result, we are currently unable 
to determine the amount, if any, of the declared dividends that the State will apply to current and future 
accounts  receivable  owed  to  us  by  the  State  or  its  entities.   In  addition,  pursuant  to  the  second 
amendment,  we  and  the  State  agreed  on  complying  with  certain  mutual  obligations  relating  (i)  to  the 
improvement of payment processes and budget management procedures; (ii) the rationalization of the use 
of water and the amount of water and sewage bills under the responsibility of the State; (iii) the recording 
of  government  entities  with  accounts  overdue  in  a  delinquency  system  or  reference  file;  and  (iv)  the 
possibility  of  interrupting  water  supply  to  these  entities  in  case  of  non-payment  of  water  and  sewage 
bills.   Finally,  this  second  amendment  did  not  amend  the  provisions  of  the  December 2001  agreement 
regarding  the  supplemental  retirement  and  pension  benefits  we  paid  from  March 1986  through 
November 2001 on behalf of the State to former employees of the State-owned companies that merged to 
form our Company. 

In 2007, we received payment installments from the State in the amount of R$326.0 million.  As of 
December 31, 2007, our dividends payable to the State, due from 2004 through 2007, were in the amount 
of R$552.0 million.  We are currently unable to determine the amount, if any, of the declared dividends 
that the State will apply to current and future accounts receivable owed to us by the State or its entities.  
The second amendment no longer requires that dividends be applied to offset accounts receivable from 
the State.  

On March 26, 2008, we entered into a commitment agreement (termo de compromisso) with the State 
with the purpose of finding an alternate solution to the deadlock related to the amount owed by the State 
to us in connection with the 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  this  agreement,  we  and  State  committed  to  hiring  specialized  companies  to 
carry out new valuations of the amounts owed to us by the State and of the reservoirs.  An independent 
consulting  firm,  FIPECAFI,  has  been  retained  to  resolve  the  disagreement  and  validate  the  amount  we 
paid from March 1986 through November 2001 on behalf of the State to former employees of the State-
owned companies that merged to form our Company, which the State has not yet agreed to reimburse us 
hereinafter referred to as the “Disputed Reimbursement Amount”.  In addition, FIPECAFI is performing, 
together  with  another  independent  consulting  firm,  a  new  evaluation  of  the  reservoirs  that  might  be 
transferred to us as amortization of the reimbursement payable by the State to us.   

On  November 17,  2008,  we,  the  State  and  DAEE  entered  into  a  third  amendment  to  the 
December 2001 agreement, pursuant to which the State recognized a debt balance payable to us totaling 
R$915.3 million, hereinafter referred to as the “Undisputed Reimbursement Amount,” as adjusted based 
on the IPCA.  We accepted on a provisional basis the reservoirs as part of the payment of the Undisputed 
Reimbursement  Amount  and  offered  to  the  State  a  provisional  settlement,  recognizing  a  credit  totaling 
R$696.3 million, corresponding to the value of the reservoirs located in the Alto Tietê region.  We and the 
State have agreed that the final offset will only be recorded when the effective transfer of the reservoirs is 
recorded  at  the  Real  Estate  Registry.   The  outstanding  balance  of  Undisputed  Reimbursement  Amount, 
amounting  to  R$219.0  million,  is  being  paid  by  the  State  in  114  consecutive  monthly  installments,  as 

104 

 
adjusted  by  the  annual  IPCA  variation,  plus  interest  accruing  at  the  annual  rate  of  6.0%.   The  first 
installment was paid in November 2008. 

In addition to the Undisputed Reimbursement Amount, there is an outstanding balance relating to the 
Disputed  Reimbursement  Amount.   As  of  December 31,  2011,  the  Disputed  Reimbursement  Amount 
amounted  to  R$1,290.7  million,  but  due  to  the  uncertainty  regarding  the  recovery  of  the  amount  our 
management  decided  not  to  recognize  the  reimbursements.   See  Note  8  to  our  consolidated  financial 
statements  as  of  and  for  the  year  ended  December 31,  2011  regarding  the  Disputed  Reimbursement 
Amount.  We and the State have agreed that the dispute relating to the Disputed Reimbursement Amount 
will not prevent us from carrying out the commitments made in the December 2001 agreement.  We are 
working with the State government to obtain legislative authorization to transfer the reservoirs to us.  

In addition, the third amendment to the December 2001 agreement provides for the regularization of 
the  monthly  flow  of  benefits.   While  we  are  liable  for  the  monthly  flow  of  benefits  to  the  former 
employees of the state-owned companies that merged to form our Company, the State shall reimburse us 
based on criteria identical to  those applied when determining the Undisputed Reimbursement Amount.  
Should  there  be  no  preventive  court  decision,  the  State  will  assume  the  flow  of  monthly  payment  of 
benefits portion deemed as undisputed. 

Finally, the third amendment to the December 2001 agreement established that the Public Attorney’s 
Office of the State of São Paulo, or the Public Attorney’s Office, would issue a revised interpretation of 
the calculation and eligibility criteria applicable to the Disputed Reimbursement Amount.  At that time, 
we  believed  that  the  Public  Attorney’s  Office  would  issue  a  revised  interpretation  which  would  have 
helped us bring the negotiations with the State to a conclusion.  However, contrary to our expectations, 
the  Public  Attorney’s Office  recent  interpretation  of  the calculation  and  eligibility  criteria  applicable  to 
the Disputed Reimbursement Amount refuted the reimbursement of the largest portion of this amount.  As 
of December 31, 2011, we had made a provision of R$1,512.1 million in our pension obligations accounts 
in respect of the Disputed Reimbursement Amount. 

Even though the negotiations with the State are still progressing, we cannot assure you that we will 

recover the receivables related to the Disputed Reimbursement Amount. 

We  will  not  waive  the  receivables  from  the  State  to  which  we  consider  ourselves  to  be  legally 
entitled. Accordingly, we will take all possible actions to resolve the issue at all administrative and court 
levels.  Should  this  conflict  persist,  we  will  take  all  the  necessary  actions  to  protect  our  interests.   On 
March  24,  2010,  we  sent  to  the  controlling  shareholder  the  official  letter  approved  by  our  executive 
committee,  proposing  that  the  matter  be  discussed  at  the  BM&FBOVESPA  Arbitration  Chamber.   In 
June 2010,  we  sent  a  settlement  proposal  to  the  Secretary  of  Treasury,  which  was  denied,  and  (iii)  on 
November 9, 2010, we filed a civil lawsuit against the State of São Paulo seeking full reimbursement of 
the  amounts  paid  as  benefits  granted  by  Law  No.  4,819/58.   Regardless  of  the  civil  lawsuit,  we  will 
continue to actively seek a settlement with the State government.  

Agreement with the State and the city of São Paulo 

On June 23, 2010 the State and the city of São Paulo entered into a convention (convênio) with the 
intermediation and consent of our Company and of the ARSESP pursuant to which they agreed to jointly 
manage  the  planning  of  and  investment  in  the  basic  sanitation  system  of  the  city  of  São  Paulo,  among 
other  things.   This  agreement  established  that  the  State  and  the  city  of  São  Paulo  would  enter  into  an 
agreement with us, granting us exclusive rights in the provision of water and sewage services in the city 
of São Paulo.  In addition, the agreement established the role of the ARSESP in regulating and overseeing 
our  activities,  and  established  a  management  committee  that  will  be  responsible  for  planning  the  water 
and sewage services and for reviewing our investment plans.  The management committee is composed of 
six members appointed for renewable two-year terms.  The State and the city of São Paulo have the right 
to  appoint  three  members  each.   We  are  permitted  to  participate  in  the  meetings  of  the  management 
committee, but we are not afforded any voting rights.  

On  June  23,  2010,  we  entered  into  a  formal  agreement  with  the State  and  the  city  of São Paulo  to 
regulate the provision of water and sewage services in the city of São Paulo for a 30-year period, which 
may be extended for an additional 30-year period.  Municipal Law No. 14,934/2009 authorized the city of 
São  Paulo  to  enter  into  an  agreement  with  us.   The  agreement  establishes,  among  other  things,  how 
specific amounts of gross revenues from the services we render should be allocated (after deduction of 

105 

 
COFINS and PASEP).  This agreement requires, among other things, (i) to invest at least 13.0% of the 
gross  revenues  from  sales  and  services  we  obtain  from  the  municipality  of  São  Paulo,  net  of  taxes  on 
revenues  in  the  improvement  of  water  and  sewage  infrastructure  in  the  city  of  São  Paulo;  (ii)  that  our 
investment plan must be compatible with the activities and programs included in the sanitation plan of the 
State, the sanitation plan of the city of São Paulo and, if necessary, the sanitation plan of the metropolitan 
region  of  São  Paulo;  and  (iii)  that  we  contribute  7.5%  of  the  gross  revenues  we  obtain  from  this 
agreement to the São Paulo Municipal Sanitation Fund. The investment plan under this agreement is not 
irrevocable and will be reviewed by our management committee every four years, especially with regards 
to  investments  to  be  executed  in  the  subsequent  period.  In  addition,  the  agreement  provides  that  the 
ARSESP,  the  State  agency  responsible  for  regulating  the  basic  sanitation  industry,  will  ensure  that  the 
tariffs charged (a) will adequately compensate us for the services we provide and (b) can be adjusted to 
restore  the  original  balance  between  each  party’s  obligation  and  economic  gain  (equilíbrio  econômico-
financeiro).   We  currently  have  an  investment  plan  in  place  that  consider  these  obligations  and  also 
addresses the compatibility  with the activities and programs  included in the sanitation plan of the State 
and  of  the  municipality  of  São  Paulo  and,  if  necessary,  the  plan  of  the  metropolitan  region  of  São 
Paulo. See  “Item  4.B.  Business  Overview—Our  Operation—Operations  in  the  City  of  São  Paulo  and 
Certain Metropolitan Regions.”  

Dividends 

We  regularly  pay  dividends  to  our  shareholders,  including  the  State  of  São  Paulo.   In  the  past,  we 
have withheld part of the dividends to which the State was entitled in order to offset it against our pending 
receivables from the State. 

In  accordance  with  our  agreements  with  the  State,  we  do  not  anticipate  that  we  will  withhold 
dividends  to  which  the  State  was  entitled  in  order  to  offset  it  against our  pending  receivables  from  the 
State in the near future. 

Cash and Cash Equivalents 

Our  cash  and  cash  equivalents  invested  with  State  financial  institutions  in  short-term  securities 
amounted to R$722.2 million, R$1,945.7 million and R$2,070.2 million, as of December 31, 2009, 2010 
and 2011, respectively.  Interest income from these investments totaled R$74.2 million in 2009, R$137.7 
million in 2010 and R$271.8 million in 2011. 

Government Guarantees of Financing 

In  some  situations,  the  federal  government,  the  State  or  government  agencies  guarantee  our 

performance under debt- and project-related agreements.  

Furthermore, the federal government has guaranteed, and the State has provided a counter-guarantee, 
in respect of the financial agreements we entered into with the IADB (i) in 1992 and 2000 for the total 
original aggregate amount of US$650.0 million related to the financing of the first and second phases of 
the Tietê River recovery project to reduce pollution; and (ii) in 2010 for the aggregate amount of US$600 
million related to the financing of the third phase of the Tiête River project. The federal government has 
also guaranteed and the State of São Paulo has provided a counter-guarantee, in respect of the financial 
agreement  we  entered  with  the  International  Bank  for  Reconstruction  and  Development  (IBRD)  in  the 
amount of US$100 million for the Water Source Program (Programa Mananciais).  

We  also  entered  into  credit  agreements  with  the  JICA,  which  were  guaranteed  by  the  federal 
government, with counter-guarantee from the State of São Paulo, for the financing of (i) the Clean Wave 
Program  for  the  Baixada  Santista  metropolitan  region,  in  August  6,  2004,  for  an  aggregate  principal 
amount of ¥21,320 million; (ii) the second phase of the Clean Wave Program, in February 2011, for an 
aggregate principal amount of ¥19,169 million; (iii) the environmental improvement program in the basin 
of  the  Billings  dam,  as  part  of  the  New  Life  Program  (Programa  Vida  Nova),  in  October  2010,  for  an 
aggregate principal amount of ¥6,208 million; and (iv) the Corporate Program for Water Loss Reduction, 
in February 2012, for an aggregate principal amount of ¥33,584 million  

The State has also guaranteed a portion of our repayment obligations under loan agreements that we 
entered into with the federal government in 1994 through its financial agent, Banco do Brasil S.A. which 
totaled R$828.2 million as of December 31, 2011.  

106 

 
In  addition,  we  are  currently  negotiating  with  Caixa  and  BNDES  for  additional  loans  to  finance 

portions of our capital expenditure program.  

For more information on the aforementioned loans, see “Item 5.B. Liquidity and Capital Resources—

Capital Sources—Indebtedness Financing.” 

Use of State-Owned Reservoirs 

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

Agreements with Lower Tariffs 

We  have  entered  into  agreements  with  public  entities,  including  State  entities  and  municipalities, 
which  manage  approximately  5,700  properties.   Under  these  agreements,  these  public  entities  pay  a 
different tariff which is approximately 25.0% lower than the tariff that applies for the public entities that 
have  not  entered  into  these  agreements,  provided  such  entities  implement  our  PURA  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 12-month term 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. 

Personnel Assignment Agreement among Entities Related to the State Government 

We  have  personnel  assignment  agreements  with  entities  related  to  the  State  Government,  under 
which  the  expenses  are  fully  passed  on  and  monetarily  reimbursed.   The  expenses  related  to  personnel 
assigned  by  us  to  other  state  government  entities  in  2009,  2010  and  2011  amounted  to  R$5.4  million, 
R$5.6 million and R$10.9 million, respectively. 

In 2011, none of our personnel had been assigned by other entities. In 2010 and 2009, the expenses 

related to personnel assigned by other entities to us totaled R$0.3 million. 

Services Obtained from State Government Entities 

As of December 31, 2011, 2010 and 2009, we had an outstanding amount payable of R$12.1 million, 
R$11.4  million  and  R$10.4  million,  respectively,  for  services  rendered  by  São  Paulo  State  government 
entities, including the supply of electric power by CESP. 

Non-operating Assets 

We lend land, free of charge, to associations, support entities, non-governmental organizations and to 
DAEE,  among  others.   Such  non-operating  assets  totaled  R$26.5  million,  R$25.4  million  and  R$21.5 
million  as  of  December  31,  2009,  2010  and  2011,  of  which  R$2.3  million  was  lent  to  DAEE,  as  of 
December 31, 2011. 

Banco do Brasil 

We  filed  a  lawsuit  against  the  Department  of  Finance  of  the  State  São  Paulo  seeking  financial 
compensation  related  to  the  transfer  of  our  exclusive  rights  in  bank  services. On  March  27,  2007,  the 
State  of  Sao  Paulo  sold  exclusive  rights  in  the  provision  of  banking  services  administration  entities 
directly  and  indirectly  in  favor  of  Banco  Nossa  Caixa.   On  May  27,  2010,  the  State  of  Sao  Paulo  sold 
them in favor of Banco do Brasil.  In this lawsuit, we were pleading financial compensation for the sale of 
its exclusive rights, requiring a percentage of the values that the State of São Paulo received from each of 
the financial institutions for the services contract entered into. 

On  June  28,  2011, we entered  into an  agreement  with  the State  of  Sao  Paulo  for  the  ,  whereby  we 
received  the  amount  of  R$63.4  million  upon  reduction,  as  compensation  of  credit  held  by  the  State, 
corresponding to interests on shareholders’ equity in the fiscal year 2010.

Transactions with SABESPREV Pension Fund 

SABESPREV is a pension fund we established to provide our employees with retirement and pension 
benefits.  The assets of SABESPREV are independently held, but we nominate 50.0% of SABESPREV’s 
board  of  directors,  including  the  chairman  of  the  board,  who  has  the  deciding  vote  pursuant  to  the 
applicable legislation.  Both we and our employees make contributions to SABESPREV pension plans.  
We contributed R$12.9 million, R$13.8 million and R$8.9 million in 2009, 2010 and 2011, respectively.  
On  May  29,  2001,  a  federal  law  was  enacted  which,  among  other  provisions,  limits  the  amount  mixed 
capital companies, like us, may contribute to their pension plans.  Specifically, the ordinary contributions 
made  by  us  to  our  pension  plans  may  not  exceed  the  contributions  made  by  the  beneficiaries  of  these 
plans.   

Our original pension plan (the Defined Benefit Plan) has an actuarial deficit.  We have commenced 
studies to manage this deficit and have also created a new, defined contribution plan, Sabesprev Mais.  
Our new plan was approved by the Previc in June 2010, after which our old plan stopped accepting new 
members.  Contributions to the new plan are also shared between plan members and Sabesp, and benefits 
are  established  based  on  the  balance  of  the  individual  member’s  account  when  payment  on  his  or  her 
benefit  begins.   This  balance  consists  of  contributions  and  profitability  obtained  when  applying 
resources.   We  intended  to  have  members  of  the  old  plan  migrate  their  reserves  to  the  new  plan.   This 
migration  was  temporarily  interrupted  by  a  judicial  order  as  a  result  of  proceedings  brought  by 
representative  entities  for our  employees  and  ex-employees.   In  October 2010,  the judge  presiding  over 
the case pronounced in an interim decision that people and reserves were not allowed to migrate between 
the  plans  until  a  further  decision  was  made.   This  decision  also  prevents  the  plan  from  charging 
contributions to account for the deficit for those who remained covered by the original plan.  

Compensation of Management 

The compensation paid by us to the members of our board of directors, board of executive officers 
and  fiscal  committee  amounted  to  R$2.6  million  in  2009,  2010,  and  2011,  and  it  refers  to  salaries  and 
other  short-term  benefits  to  employees  and  management.   An  additional  amount  of  R$0.8  million, 
R$0.8 million and R$1.1 million related to the bonus program, was accrued in 2009, 2010 and 2011.

Legal Proceedings 

In  the  ordinary  course  of  our  business,  we  are  a  party  to  judicial  and  administrative  proceedings 
relating to civil, environmental, labor and tax matters.  As of December 31, 2011, we estimated that these 
legal proceedings totaled R$24,152.0 million (excluding the amount of R$133.1 million related to court 
deposits).  This amount was based on probable, possible and remote losses and on the value attributed to 
the lawsuit by the plaintiffs in some cases and on the economic value of the lawsuits in others.  Out of the 
total amount of contingencies as of December 31, 2011, approximately R$2,367.2 million relate to tariff-
related legal proceedings and consumers claims, approximately R$1,147.8 million relate to contractors’ 
claims, approximately R$1,105.7 million relate to tax proceedings, approximately R$349.7 million relate 
to  labor  proceedings,  approximately  R$18,405.1  million  relate  to  civil  public  actions  related  to 
environmental matters and approximately R$776.4 million relate to other civil matters.  As of December 
31,  2011,  the  provision  for  legal  contingencies  totaled  R$1,571.8  million  (excluding  the  amount  of 
R$120.7  million  related  to  court  deposits),  of  which  R$618.5  million  relate  to  tariff-related  legal 
proceedings and consumers claims, R$420.8 million relate to contractors’ claims, R$76.4 million relate to 
tax  proceedings,  R$156.5  million  relate  to  labor  proceedings,  R$121.2  million  relate  to  civil  public 
actions related to environmental matters and R$178.4 million relate to other civil matters.   

108 

 
   
The  table  below  sets  forth,  as  of  December  31,  2011,  our  estimated  contingencies  with  respect  to 

legal proceedings, categorized by potential risk of loss: 

Expected probable loss 
Expected possible loss 
Expected remote loss 
Total 

Total Value 
(in thousands of reais)  

1,571,829
2,621,800
19,958,346
24,151,975

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

We  cannot  give  any  assurances  either  as  to the  sufficiency  of  the provisioned  amount  to  cover  the 
contingencies or as to the total amount of potential liabilities that we may incur or penalties that may be 
imposed.  We may not obtain a favorable outcome in the administrative or court proceedings to which we 
are a party.  In addition, the total amount of the contingencies, based on the value attributed to the lawsuit 
by the plaintiff, may not correspond to the economic value of the lawsuits, which may be substantially 
higher  than  the  total  estimated  amount  of  contingencies.  If  the  economic  outcome  of  these  lawsuits  is 
higher than the amount attributed to the lawsuit by the plaintiff or, in the event the total amount of our 
provisions  are  not  sufficient  to  pay  the  contingencies  due,  we  could  incur  greater  costs  than  those  that 
were originally estimated. If these costs are significant, our results of operations and financial condition 
could  be  negatively  affected.  See  “Item 3.D.  Risk  Factors—Risks  Relating  to  Our  Business—Any 
substantial monetary judgment against us in legal proceedings may have a material adverse effect on us.” 

Civil Public Actions Related to Environmental Matters 

We have been sued by the Public Prosecution Office of the State of São Paulo (Ministério Público do 
Estado de São Paulo), by some municipalities and by some non-governmental organizations in a number 
of environmental civil public actions:  (i) seeking that we cease releasing raw sewage into certain local 
water courses; (ii) in some cases seeking remedies for environmental damages, which have not yet been 
specified  and  evaluated  by  the  court’s  technical  experts;  and  (iii)  seeking  to  require  us  to  install  and 
operate sewage treatment facilities in the locations referred to in the civil public actions. In each case, we 
are  subject  to  daily  fines  for  non-compliance.   In  our  response  to  these  lawsuits  we  emphasize  that  the 
installation  and  operation  of  sewage  treatment  facilities  in  the  locations  referred  to  in  the  civil  public 
actions is included in our investment plan and that the immediate cessation of the release of raw sewage 
into  the  relevant  local  water  courses  would  hinder  us  from  collecting  sewage,  a  primary  necessity,  in 
those  locations,  causing  even  more  damage  to  the  environment  and  public  health.   There  have  already 
been  unfavorable  judicial  decisions  against  us.  The  effects  may  include:   (i)  investment  in  works  or 
services not considered by the long-term investment plan; (ii) early execution of works or services that 
were considered for execution in future years in the long-term investment plan; (iii) payments related to 
environmental  indemnification;  and  (iv)  a  negative  impact  on  our  image  in  national  and  international 
markets and in public bodies. 

Although we are not able to predict the final outcome of these lawsuits, we believe that the outcome, 

if unfavorable to us, may have a material adverse effect on us. 

The  civil  public  lawsuits  related  to  environmental  matters  to  which  we  are  party  include  the 

following: 

(cid:131) The Public Prosecution Office of the State of São Paulo has brought a civil public action 

requesting remedies due to environmental damage caused by the release of sludge from the Rio 

109 

 
   
   
   
  
  
      
Grande water treatment facilities into certain receiving waters and the Billings reservoir and 
seeking the immediate cessation of this activity and the implementation of an environmental 
recovery project.  The Trial Court ruled in our favor, and there was a subsequent appeal against 
this decision.  In May 2006, the appellate court ruled against us and ordered us to cease the release 
of sludge within a year from the final ruling.  The court also determined that the environmental 
recovery must be carried out within two years of the date of the ruling, under the penalty of a daily 
fine of R$10,000 to compensate for environmental damage.  We appealed from this decision and 
the court decided against us in a final decision.  We are currently studying a proposal to be made 
to the Public Prosecution Office of the State of São Paulo on how to implement the environmental 
recovery we have been imposed.  As of December 31, 2011, we had provisioned R$1.2 million for 
the effects of this lawsuit. 

(cid:131) A public civil action filed by the Public Prosecution Office of the State of São Paulo against us 

and the Cotia Mayor’s Office seeking individual and joint adverse judgments against the 
defendants and requesting:  (i) the permanent cessation of the release of untreated water effluents 
into the Cotia River or its tributaries, subject to a daily fine in the case of non-compliance; (ii) the 
treatment of sewage prior to its release into the Cotia River, under the penalty of a daily fine in the 
event of non-compliance; (iii) the full restoration of soil, of surface and underground water bodies 
and of vegetation to their original condition, under the penalty of a daily fine in the event of non-
compliance; (iv) the payment of compensation for environmental damage caused to soil, water 
sources and underground and surface water bodies that cannot be recovered. The appellate court 
rendered decisions favorable to us with respect to items (i), (iii) and (iv) mentioned above.  
According to evaluations by the court’s technical expert, as of October 17, 2006, compensation for 
environmental damages was R$826.8 thousand or R$5.8 million if damage caused to the 
neighboring Cotia River is included.  This amount is under discussion, and its approval is subject 
to a final decision by the court of first instance.  Our legal counsel assessed the risk of loss as 
probable.  In December 2011, the court’s technical expert’s evaluation for the compensation was 
adjusted to R$11.6 million.  The lawsuit is currently being enforced against us. We are in 
negotiation with the Public Prosecution Office of the State of São Paulo to settle this lawsuit. 

 (cid:131)  In 2003, the Piracicaba Civil Entities Coordination Board filed a public civil action against us, the 
ANA and the Government of the State of São Paulo, seeking remedy for damage caused by the 
use of the Piracicaba, Jundiaí and Capivari river basins to supply the São Paulo metropolitan 
region through the Cantareira Water System for nearly 30 years.  The value attributed to the claim 
was R$11.4 billion on December 10, 2003, and later adjusted to R$17.2 billion as of 
December 31, 2011. The lawsuit was dismissed on July 8, 2011, but the Piracicaba Civil Entities 
Coordination Board filed a motion for the clarification of a certain aspect of that decision. Having 
the motion rejected, the plaintiff may file an appeal to the Superior Courts. So far no value has 
been set for the damages alleged.  Our legal counsel assessed the risk of loss as remote.  No 
provision has been made for this lawsuit.

 (cid:131)  The Public Prosecution Office of the State of São Paulo has filed a public civil action against us, 

AES Eletropaulo, DAEE, CETESB and the State Secretariat of Treasury seeking a joint 
condemnation for alleged environmental damage caused by the reversal of the Pinheiros River 
into the Billings Dam.  A Trial Court found the defendants guilty and, based on an expert’s report 
which estimated the amount of damages, ruled that the defendants jointly pay R$284.5 million in 
damages.  As of December 31, 2011, the amount of damages totaled R$618.3 million, after 
monetary adjustment.  We, DAEE, AES Eletropaulo, CETESB and the State Treasury 
Department have filed an appeal against the ruling at the appellate court.  The appellate court 
ruled in our favor, and the plaintiff appealed from this decision.  We are currently awaiting the 
decision on the plaintiff’s appeal.  Our legal counsel assessed the risk of loss as remote.  No 
provision has been made for this lawsuit.

 (cid:131)  The Public Prosecution Office of the State of São Paulo has filed a civil public action against us 
seeking (i) that we cease releasing untreated sewage into receiving waters and into the soil; (ii) 
that we implement a sewage system in the municipality of Vargem Grande Paulista and the 
necessary infrastructure for the sewage treatment; and (iii) indemnification for irreversible 
damages caused to the environment and public health, subject to daily fines.  The trial court ruled 
partially against us, and we appealed unsuccessfully. We have filed appeals for the Superior 

110 

 
      
      
   
   
   
  
Courts. Our legal counsel assessed the risk of loss as probable.  The value attributed to the lawsuit 
was R$3.0 million as of November 20, 2007, and later adjusted to R$3.8 million as of 
December 31, 2011. 

 (cid:131)  The Public Prosecution Office of the State of São Paulo filed a civil public action against us and 
the Piracaia Mayor’s Office seeking that we cease to release untreated residential sewage in the 
Atibaia River or be subject to specific performance or a daily fine.  The value attributed to the 
lawsuit was R$3.5 million as of July 11, 1996, and later adjusted to R$100 thousand, which was 
updated to R$262 thousand as of December 31, 2011. This lawsuit is in its initial stage, pending 
judgment from the trial court.  Our legal counsel assessed the risk of loss as possible. No 
provision has been made for this lawsuit.

 (cid:131)  The Public Prosecution Office of the State of São Paulo filed a civil public action against us 
seeking that we (i) cease to release untreated sewage effluents into the Capivari river in the 
municipality of Campos do Jordão within 540 days from the filing of the lawsuit, subject to a 
daily fine of R$100,000; and (ii) fully restore the environmental damage or indemnify the State 
for such damages if restoration is not viable.  The court of first instance ruled against us, and we 
appealed. The appellate court also ruled against us, but reduced the daily fine to R$10,000. We 
have appealed the appellate court’s ruling and are currently waiting for a ruling on our appeal.  
Our legal counsel assessed the risk of loss as probable. We have entered into a settlement with the 
Public Prosecution Office of the São Paulo on July 11, 2011 agreeing to build a sewage treatment 
station by December 31, 2013.  As compensation for the environmental damage, we have agreed 
to recover 10 (ten) hectares of the damaged area in Campos do Jordão, planting approximately 
16,667 trees, of which 39% should be of exotic species for public exhibition at certain blocks of 
Avenue Emílio Ribas, at Capivari. We also agreed to expand the sewage system of that 
municipality and to create a center for environmental education.

 (cid:131)  On April 12, 2005, the Federal Public Prosecution Office and the Federal Government sued us 

and the Santos Mayor’s Office requesting (i) the full restoration of the area where the outlet pipes 
were built to its original condition, with appropriate technical safeguards, and the conservation of 
the remaining trees; (ii) the maintenance of the area in a condition that is adequate for its use for 
the population; (iii) that an environmental license be obtained before any modification to the 
sewage outlet pipes, with the requirement that the license and an obligatory environmental impact 
study and report (Estudo Prévio de Impacto Ambiental e Relatório de Impacto Ambiental, or EIA-
RIMA, be submitted for approval to the appropriate federal authorities; and (iv) the restoration of 
the area to the condition it was in prior to the construction of the sewage outlet pipe platform, 
provided this is determined to be feasible pursuant to the EIA-RIMA. The trial court ruled in our 
favor, but the Federal Public Prosecution Office and the Federal Government filed an appeal 
against that decision.  We have submitted additional evidence for consideration, and we are 
waiting for the decision of the Regional Federal Court.  Our legal counsel has assessed the risk of 
loss as possible. The value attributed to the lawsuit was R$2.1 million as of December 31, 2011. 
No provision has been made for this lawsuit.

(cid:131) On October 19, 2009, the Public Prosecution Office of the State of São Paulo filed a civil public 
action against us and the municipality of Itatiba seeking that we (i) cease releasing untreated 
sewage in Itatiba or be subject to a daily fine of R$10,000; (ii) fully restore within one year the 
soil, the surface and underground water bodies and vegetation to their original condition, or be 
subject to a daily fine of R$10,000 in the event of non compliance; (iii) indemnify the State for 
damages when restoration is not viable; and (iv) indemnify the State in an amount not less than 
R$2.0 million for moral damages.  This lawsuit is in its initial stage and is pending judgment from 
the trial court.  As of December 31, 2011, the value attributed to this lawsuit was R$31.4 
thousand.  Our legal counsel assessed the risk of loss as possible.  No provision has been made for 
this lawsuit. 

(cid:131) On August 8, 2008, the Public Prosecution Office of the State of São Paulo won a civil public 
action against us requiring us, within a maximum of three years, to treat all domestic sewage in 
Águas de Santa Bárbara before releasing it into any waterway, or be subject to a daily fine of 
R$1,000, as from August 8, 2008 for a maximum period of 18 months.  We appealed and were 
waiting the appeal court’s judgment until we entered entered into a settlement with the 

111 

 
  
  
   
  
   
  
              
       
Prosecution Office of the State of São Paulo on August 05, 2011. Through this settlement, we 
agreed to create a treatment facility for the domestic sewage of Águas de Santa Bárbara until 
October 2012, and also to abstain from releasing any non-treated domestic sewage into a 
waterway in that area.   

(cid:131) A civil public action was brought against us by the Public Prosecution Office of the State of São 
Paulo.  We appealed an unfavorable decision of the trial court, and the appeal court ruled against 
us, requiring us (i) to cease to release any untreated sewage into the river system in the Guareí 
region, or be subject to a fine of R$150,000 for each violation; (ii) to invest as necessary in the 
municipality of Guareí’s water treatment and sewage system so as to complete within 180 days all 
works necessary for sewage treatment, or be subject to a daily fine of R$100,000; (iii) to pay an 
indemnity in respect of all damage caused to the environment and to clean up any such damage in 
settlement of the judgment. The judgment was not clear as to the fines imposed and this led to an 
appeal, which the court refused in May 2010.  After the appeal court ruled against us, we applied 
to have this lawsuit heard by the State of São Paulo Court of Special and Extraordinary Measures 
(Recursos Especial e Extraordinário pelo Tribunal de Justiça do Estado de São Paulo), and that 
court is currently considering whether to hear the case.  Our legal counsel assessed the risk of loss 
as probable.  As of December 31, 2011, the value attributed to this lawsuit was R$38.4  million, 
based on the settlement offered by the State Public Prosecution Office in July 2010, and we have 
recorded provisions in this amount as of that date.

(cid:131) The Public Prosecution Office of the State of São Paulo filed a civil public action against us, 
requiring us (i) to cease to release any untreated sewage from the Araça pre-treatment plant 
(Estação de Pré Condicionamento), or EPC, into the São Sebastião canal without obtaining the 
necessary environmental licenses, or be subject to a daily fine of R$100,000; (ii) to obtain and 
maintain the necessary environmental license to operate the Araça EPC, or be subject to a daily 
fine of R$100,000; (iii) to release into the São Sebastião canal only domestic sewage that complies 
with legal guidelines; (iv) to comply with all of the technical requirements set out in the 
environmental license, as well as the requirements specified following inspections by the 
CETESB; and (v) to pay an indemnity of R$50.0 million for environmental damage. The 
preliminary judgment was deferred, and we were required (i) to present to the court within six 
months the environmental license for the Araça EPC, or be subject to a daily fine of R$100,000, 
and (ii) to present to the court within 30 days a contract with a company to carry out an 
independent technical study with monthly reporting to monitor and collect samples from the areas 
of São Sebastião canal where there are underwater outlets from the Araça EPC, as well as from the 
beaches and mangroves within 8 km to the north of south of the Araça EPC. The sediment 
samples from the mangroves were required to be analyzed for the existence of fecal coliforms as 
well as water quality.  This lawsuit is in its initial stage and is pending judgment from the court of 
first instance. Our legal counsel has assessed the risk of loss as possible.  The value attributed to 
the lawsuit as of December 31, 2011 was R$123.4  million.  No provision has been made for this 
lawsuit. 

 (cid:131)  The municipality of Águas de São Pedro filed a civil public action against us on September 14, 

2004, with a request for summary judgment or the imposition of a daily fine.  This lawsuit aims to 
require us to undertake works and services necessary to remove the direct discharge of sewage 
beside the green areas and the Pantanal source and lake that are located close to Rua dos 
Pinheiros, in the Bairro Jardim Iporangadistrict of the municipality of Águas de São Pedro.  It 
also aims to require us to pay indemnities for alleged damage caused to the environment, to health 
and to citizen’s property.  On June 26, 2006, the court of first instance ruled that the claim was 
without merit.  However, on September 22, 2009, the appeals court ruled that the claim was 
proven and granted an injunction, ordering us to comply with the requirement to clean up the 
environmental damage within 180 days in satisfaction of the judgment, and imposing a daily fine 
of R$5,000.  We appealed from this decision, and the court decided against us.  We filed another 
appeal from this decision and are currently awaiting its decision.  Our legal counsel has assessed 
the risk of loss as probable.  The value attributed to this lawsuit as of December 31, 2011 was R$2 
million, and we have recorded provisions in this amount as of that date.  Currently, we are 
awaiting the response from the State of São Paulo Court of Special and Extraordinary Measures 
(Recursos Especial e Extraordinário pelo Tribunal de Justiça do Estado de São Paulo) in relation 
to this lawsuit.

 (cid:131)  The Public Prosecution Office of the State of São Paulo filed a civil public action against us for 
the indemnification on environmental damages and for us to cease the  discharge of untreated 
sewage into the Alegre river in the area of the municipality of Paraguaçu Paulista. The first 
instance judge has ruled against us so that we (i) cease the  discharge of untreated sewage into 
Alegre river; (ii) to invest as necessary in that municipality’s water treatment and sewage system; 
and (iii) pay indemnities for alleged damage caused to the environment, which the court arbitrated 
at R$168.9 million. The court has also imposed a daily fine in case of disobedience of item (i) and 
(ii) above.  We appealed from this decision, and the court decided against us.  We then entered 
into a settlement with the Public Prosecution Office of the State of São Paulo, having agreed to 
pay R$34 million as indemnity for environmental damages and invest R$8.7 million within 54 
months on the water treatment and sewage system. The deadlines and planning for the 
performance of the agreement have not yet been settled.  Our legal counsel assessed the risk of 
loss as probable.  As of December 31, 2011, we provisioned R$43.7 million for this matter. 

 (cid:131)  The municipality of Atibaia filed a civil public action against us on August 2010, for the 
indemnification on environmental and urban damages related to flood that took place in 
December 2009 and January 2010 and for us to take preventive steps to avoid new damages 
related to similar events. The first instance judge has granted the municipality of Atibaia an 
injunction ordering us to perform emergency repairs around the area of the Atibaia river, or be 
subject to a daily fine of R$50,000. We appealed from that decision, and the injunction was 
suspended by the second instance court. We currently await the decision of the superior courts on 
the injunction.  We still await a final judgment to resolve all matters of the lawsuit. The estimated 
amount for this lawsuit is R$ 1.9 million. Our legal counsel assessed the risk of loss as possible 
and no provision was made for this lawsuit.

We are currently involved in other environmental lawsuits and administrative proceedings against the 
release  of  untreated  sewage  in  the  municipalities,  which  have  been  evaluated  as  probable  and  possible 
losses.  The amounts provisioned may not always represent the final amount to be paid as compensation 
for the alleged damages, in view of the current status of the lawsuits and since our management cannot 
reasonably  estimate  the  amounts  of  future  disbursements.   As  of  December 31,  2011,  the  total  amount 
provisioned was R$121.2 million. 

Labor Proceedings 

We are party to labor proceedings, mainly regarding unpaid overtime, health and safety conditions in 
the  workplace,  among  others.   We  make  provisions  for  part  or  the  entire  amounts  involved  in  the 
proceedings.  For those cases in which the probability of loss is assessed as probable, we provision the 
full amounts being discussed. 

As of December 31, 2011, we were party to approximately 5,432 labor proceedings and one public 
civil action filed by some of our current and former employees.  Some of these lawsuits seek to negotiate 
certain benefits granted by Law No. 4,819 of August 26, 1958.   Our position in these lawsuits is that the 
State government, and not us, should be responsible for the payments due to the plaintiffs.  In the public 
civil action filed against us and the State Treasury, a temporary injunction was granted in the trial court 
requiring us to pay the benefits set forth in Law No. 4,819/58 to all the plaintiffs.  A trial court ruled on 
April 5, 2005, granting the relief sought under this proceeding and confirming the temporary injunction 
requiring us to continue to pay the benefits.  We have appealed this decision.  There are currently other 
pending individual lawsuits discussing the same claims, and up to the date of this report neither we nor 
the  State  government  had  reached  an  agreement  as  to  the  indemnification  amounts  related  to  these 
proceedings.  

In  order  to  continue  to  seek  reimbursement  of  the  amounts  related  to  the  payment  of  retirement 
benefits  and  pensions  paid  by  us  that  our  management  understands  is  in  fact  owed  by  the  State 
government,  we  have  taken  the  following  measures:   (i)  on  March  24,  2010,  we  sent  a  letter  to  our 
controlling  shareholder  in  an  attempt  to  start  an  arbitration  proceeding  before  the  BM&FBOVESPA 
arbitration chamber, (ii) In June 2010, we sent a settlement proposal to the Secretary of Treasury, which 
was denied, and (iii) on November 9, 2010, we filed a civil lawsuit against the State of São Paulo seeking 
full reimbursement of the amounts paid as benefits granted by Law No. 4,819/58 and we are waiting on 

113 

 
  
   
  
  
     
the court’s decision.  Regardless of the civil lawsuit, we will continue to actively seek a settlement with 
the State government. 

Among the mentioned labor proceedings, as of December 31, 2011, we were party to two collective 
lawsuits brought by the syndicate of the workers of the water and sewage systems and environment of the 
State of São Paulo (SINTAEMA). The first relates to the scheduling of the workers and we had a ruling 
against us in the amount of approximately R$62.6 million. This lawsuit in currently under enforcement 
calculations. A second lawsuit filed by that syndicate relates to the increase in 1.5% of our salary base for 
2010/2011, as well as overtime adjustments. The court has ruled against us and we have filed an appeal to 
the superior labor court, where the appeal is currently under review. The approximated amount in dispute 
in this lawsuit is R$11.8 million as of December 31, 2011, with a probable risk of loss. 

As  of  December 31,  2011,  the  total  amount  in  controversy  in  the  labor  proceedings  was  R$301.6 
million for risks considered as probable and possible losses.  We have established a provision of R$156.5 
million  as  of  December 31,  2011  for  these  contingencies,  including  the  lawsuits  described  in  the 
preceding paragraphs, based on calculations made by our legal and human resources departments.   

Tax Proceedings 

Our tax proceedings and our contingency reserves for tax proceedings refer mainly to tax collection 
suits resulting from different interpretations by us and the competent government authority with respect to 
the applicable law.  The tax proceedings to which we are party include the following: 

(cid:131) We are challenging the city of São Paulo’s taxation of the use of public areas for the installation of 
water and sewage mains for the provision of public sanitation services.  The tax was originally 
established by municipal decree No. 38,139/99 and later replaced by municipal decree No. 
40,532/2001 and finally by the municipal Law No. 13,614/2003.  On February 22, 2000, we filed 
a writ of mandamus requesting an injunction to challenge this tax.  This first lawsuit covers the 
taxation before the enactment of municipal Law No. 13,614/2003.  The trial court ruled partially 
in our favor, by prohibiting the requirement to pay the tax provided for in this law, and the 
appellate court confirmed that the tax was not due.  The city of São Paulo appealed this decision, 
and a final decision is pending.  On April 20, 2004, we filed a writ of mandamus requesting 
temporary injunction against the collection of this tax based on challenges to Law No. 
13,614/2003.  The court granted this injunction.  The São Paulo city government appealed this 
decision, and an appellate court decision is still pending.  We cannot estimate the potential 
increase in our expenses should we have to pay this tax for the use of public areas for the 
installation of water and sewage mains for the provision of public sanitation services should we be 
required to pay such tax since 1999.  We have not provisioned for any type of potential expense 
deriving from this municipal tax.

(cid:131) The municipality of São Paulo has notified us of alleged infractions on the payment of Brazilian 
Service Tax (Imposto Sobre Serviço), or ISS. This charge is related to the enactment of municipal 
Law No. 13,476/2002, before which we were exempted from such charge. The municipality is 
charging the amount of approximately R$223.9 million in charges and penalties. We filed a writ 
of mandamus against the administrative decision that imposed those charges. The trial court 
originally granted a preliminary injunction in our favor in the writ of mandamus, suspending the 
levy of the tax, but later ruled against us.  In July 2005, we filed an appeal to maintain the 
injunction previously granted, which was denied in January 2012. We filed a motion to clarify 
items in this decision, which is under the review of the court.  On the same matter, we filed a 
lawsuit confronting the basis for the charge, challenging Law No. 13,476/2002. We have been 
granted an injunction within this lawsuit that suspended the levy of the tax until the final judgment 
from the court. We are currently waiting for a final decision on this matter. The risk of loss has 
been considered as possible and we have not provisioned for any type of potential expense 
deriving from this municipal tax.

105 

114 

 
  
      
      
   
 (cid:131) We proposed to carry-over losses from previous years to offset an income tax liability of 

approximately R$56.1 million and a social contribution tax liability of approximately R$8.7 
million.  These amounts refer to the period between January and April 2003.  In 2005, the Federal 
Revenue Service denied the set-off of approximately R$11.2 million related to income tax liability 
and R$0.7 million related to social contribution tax liability, totaling R$11.9 million, and allowed 
us to compensate the remaining portion.  We appealed this decision, and our request was partially 
granted.  As of December 31, 2011, we recorded a provision of R$1.1 million as a probable loss.

 (cid:131) In 2006, the Federal Revenue Service concluded that, for the year 2001, we had an income tax 

liability and social contribution tax liability totaling R$277.0 million (R$379.3 million, as adjusted 
as of December 31, 2011) and initiated administrative collection proceedings against us.  We filed 
an administrative objection to this collection proceeding.  Based on the opinion of our legal 
counsel, the risk of loss is remote with respect to approximately 90.0% of this amount and a 
possible risk of loss with respect to the remaining 10.0%.  

 (cid:131) In 2008, the Federal Revenue Service denied six requests for compensation to offset income tax 
and social contribution tax liabilities.  We proposed to offset income tax and social contribution 
tax paid in excess against our tax liability.  The amount involved in these proceedings was R$44.7 
million as of December 31, 2011.  Based on the opinion of our internal legal counsel, the risk of 
loss is possible and no amount was provisioned for this proceeding.

 (cid:131) In November 2004, we filed a writ of mandamus against the municipality of Bragança Paulista 
regarding the imposition of a new tax for the use of public areas for the installation of water and 
sewage mains for the provision of public sanitation services.  On February 16, 2005, we were 
granted a temporary injunction suspending the imposition of this tax and preventing the 
municipality from collecting any current or future amounts due in respect of this tax until a ruling 
is rendered by the trial court.  In June 2005, the trial court ruled in our favor by confirming the 
injunction.  In July 2005, the municipality of Bragança Paulista filed an appeal to the São Paulo 
appellate court, which was denied.  Although the municipality may take additional judicial steps, 
it is probable that their attempts will be unsuccessful.

 (cid:131) We proposed to carry-over losses from the years 1997 and 1998 to offset an income tax liability of 
approximately R$41 million.  This amount refers to the period between July and September 2002. 
The Federal Revenue Service denied the set-off and we appealed this decision.  Based on the 
opinion of our internal legal counsel, the risk of loss is possible and no amount was provisioned 
for this proceeding.  

 (cid:131) On June 23, 2010, we have entered into an agreement with the municipality of São Paulo for 
public water supply and sewage services. As part of this settlement, certain tax collections 
between the parties were settled amicably. As of December 31, 2011, the total amount related to 
tax collection proceedings that remained outstanding from the municipality of São Paulo was 
R$58.2 million, of which we provisioned R$27.7 million as  a probable loss. 

We cannot predict the outcome of any of these lawsuits, nor can we assure you that, in the event of 
an  adverse  decision,  we  will  be  able  to  pass  on  to  our  customers  any  increase  in  our  deductions  from 
gross revenue, operating expenses or other expenses.  See Item 3.D. Risk Factors - Risks Relating to Our 
Business  -  Any  substantial  monetary  judgment  against  us  in  legal  proceedings  may  have  a  material 
adverse effect on us.” 

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 

115 

 
   
  
   
  
      
      
      
     
     
     
   
construction, development or improvement of water and sewage systems operated by us.  However, we 
are  required  to  provide  compensation  to  affected  property  owners  based  upon  appraised  fair  market 
values.  Although  we  generally  provide  compensation  to  property  owners  on  the  basis  of  negotiated 
settlements, we are a party to many lawsuits related to compensation awards.  

As  of  December 31,  2011,  the  future  disbursement  was  estimated  at  R$448.6  million,  as  to  all 
proceedings regarding expropriation and easements.  These payments are made over the years, according 
to each court order or settlement.  After making each payment, we will obtain the title to the respective 
real property which will be recorded as an asset belonging to us after being expropriated.  We have not 
provisioned any amounts with regard to these proceedings.  

Concession-Related Legal Proceedings 

In December 1997, the municipality of Santos enacted a statute expropriating our water and sewage 
systems  located  in  Santos.  We  filed  a  writ  of  mandamus  requesting  a  temporary  injunction  against  the 
expropriation,  which  was  denied  by  the  trial  court.  This  decision  was  subsequently  reversed  by  the 
appellate court, which then issued a temporary injunction suspending the effectiveness of the statute. By 
August 2, 2002, both the trial and appellate courts had ruled in our favor, but we are currently waiting for 
a final decision.  

On  December 20, 2000, we brought  an  action  against  the  municipality  of Santos for payments  due 
under  the  concession  agreement.   Both  parties  appealed  the  decision  of  the  courts  of  first  and  second 
instance,  and  we  are  currently  awaiting  the  decision  of  the  higher  appeal  court.  We  continue  to  render 
water and sewage collection services in the municipality of Santos.  

On March 25, 2005, the municipality of Itapira approved a decree revoking our concession contract. 
In addition, a municipal law was enacted revoking an earlier law authorizing the municipality to enter into 
the  contract  with  us.  The  municipality  of  Itapira  has  further  filed  a  repossession  lawsuit  seeking  to 
repossess all of the reversible assets, rights, and privileges transferred to us in connection with water and 
sewage  collection  services,  and  has  obtained  an  injunction  which  was  later  confirmed  by  an  appellate 
court  decision.   We  appealed  this  decision  but  we  later  decided  to  waive  this  appeal  and  filed  a 
compensation lawsuit against the municipality of Itapira.  

The municipality of Tuiuti has filed a lawsuit seeking to recognize the inexistence of any judicial or 
legal grounds for us to provide water and sewage collection services in the municipality of Tuiuti, and to 
confirm the legality of the expropriation of these services by the municipality.  We filed an answer to the 
lawsuit requesting that the trial court (i) confirm the existence of a legal relationship between us and the 
municipality of Tuiuti; and (ii) award damages for the expropriation of our assets.  The trial court ruled 
against  us  but  awarded  us  an  indemnity  of  R$541.0  thousand, to  be  updated  since  March 2006.   Both 
parties appealed this decision, and the court decided partially in our favor increasing the amount related to 
damages to R$1.1 million.  We are not currently operating in the municipality of Tuiuti.  

The municipality of Cajobi has filed a repossession lawsuit. This lawsuit requests the repossession of 
water  and  sewage  collection  services  due  to  the  termination  of  the  concession  agreement  on 
November 13, 2006, and an indemnity for all amounts paid to us for water and sewage collection services 
after  November 2006,  as  well  as  payments  for  the  use  of  all  the  reversible  assets,  rights  and  privileges 
transferred to us in the concession agreement.  The municipality has been rendering the water and sewage 
collection services since May 29, 2007, based on a judgment by the court of first instance. The amounts 
involved in this lawsuit are still being evaluated in the judicial proceedings. 

The municipality of Araçoiaba da Serra has filed a repossession lawsuit requesting the repossession 
of water and sewage collection services due to the termination of the concession agreement entered into 
with  us  and  an  indemnity  for  all  amounts  paid  to  us  for  water  and  sewage  collection  services  after  the 
termination on September 23, 2006, as well as payment for the use of all the reversible assets, rights and 
privileges  transferred  to  us  in  the  concession  agreement.   A  temporary  injunction  was  granted  by  the 
appellate court in favor of the municipality of Araçoiaba da Serra and confirmed by the superior courts. 
The  first  instance  court  has  ruled  in  favor  of  the  municipality  in  their  requests,  to  which  we  filed  an 
appeal currently under the review of the trial court.  

We  have  filed  a  lawsuit  to  collect  indemnities  from  the  municipalities  of  Diadema  e  Mauá. 
These indemnities  result  from  the  unilateral  termination  by  these  municipalities  of  the  concession 

116 

 
contracts entered with us in 1995. We have invested in the construction of water and sewage collection 
systems in these municipalities to render the contracted services. As a result of the termination of these 
concession agreements, the municipalities started to directly render water and sewage collection services 

With  respect  to  the  collection  suit  against  the  municipality  of  Diadema,  in  October  2009,  the  trial 
court  ruled  in  our  favor.  The  municipality  appealed  from  the  decision  to  the  appellate  court,  and  the 
appellate  court  decision  is  still  pending.   In  December 2008,  we  entered  into  a  memorandum  of 
understanding  with  the  State  of  São  Paulo,  the  municipality  of  Diadema  and  the  State  Secretariat  for 
Sanitation  and  Water  Resources,  formerly  known  as  the  State  Secretariat  for  Sanitation  and  Energy 
(Secretaria  de  Saneamento  e  Energia  do  Estado  de  São  Paulo).   This  memorandum  establishes  our 
agreement  to  conclude  negotiations  and  settle  all  outstanding  amounts  and  stayed  the  collection 
proceedings  we  had  filed  against  the  municipality  of  Diadema.   In  2011,  the  municipality  of  Diadema 
agreed with us to develop a share infrastructure for the provision of water and sewage services through a 
mixed-capital company called Companhia de Água e Esgoto de Diadema, or CAED. The amount owned 
to  us  by  that  municipality  would  be  returned  to  us  through  capital  participation  in  CAED,  through  the 
assignment of 49.9% shares of the new company to us.  

With respect to the collection suit against the municipality of Mauá, the trial court ruled in our favor, 
ordering  the  municipality  to  pay  us  R$153.2  million  as  compensation  for  our  losses.   The  municipality 
appealed this decision to the appellate court, which upheld the trial court’s decision in August 2008.  The 
municipality  appealed  to  the  Superior  Court,  which  have  denied  the  appeal  making  the  decision  in  our 
favor final.  We are currently pursuing to collect the amount owed.   

We have recorded the indemnities to be received from the municipality of Diadema as non-current 
assets representing long-term receivables.  As of December 31, 2011, this amount totaled R$60.3 million. 

Following the expiry of our concession contract with the municipality of Iperó, the municipality filed 
a  repossession  lawsuit  requesting  the  repossession  of  assets  relating  to  water  and  sewage  services.  In 
response, we filed a lawsuit on December 30, 2009 to maintain possession or to collect indemnities.  A 
temporary injunction was granted in our favor on January 5, 2010, but it was thereafter annulled by the 
court  of  first  instance  on  January 6,  2010.   We  filed  an  interlocutory  appeal,  but  it  was  not  accepted. 
Currently,  this  lawsuit  is  at  the  appeals  stage  with  respect  to  the  submissions  by  both  parties.  We  also 
filed a precautionary early evidence order in the jurisdiction of the Secretariat of Treasury, which resulted 
in a summary judgment requiring the early presentation of evidence to establish what assets are related to 
the provision of the services rendered by us in the municipality of Iperó. 

The municipality of Tarumã filed a lawsuit against us in July 2010 requesting an interim injunction 
requiring  (i) the  repossession  of  existing  assets  necessary  for  providing  water  and  sewage  collection, 
distribution  and  treatment  services,  and  (ii)  the  presentation  of  documentation  demonstrating  current 
income and expenses in the municipality and invoices for services and goods purchased by us to provide 
services, in order to calculate the indemnity due under article 35, paragraph 4, of the Federal Concessions 
Law 8,987/95. The lawsuit requested (i) a search warrant if we did not provide the income and expenses 
information and invoices, (ii) the imposition of a daily fine against us and (iii) that the interim injunction 
be  converted  into  a  permanent  order,  with  the  declared  assets  remaining  under  the  control  of  the 
municipality until the payment of the indemnity provided for under article 36 of the Federal Concessions 
Law. The court denied the municipality’s requested and we restarted the water distribution and sewage 
collection services in that area. We await a final decision from the court on the matter.    

We  filed  an  ordinary  action  against  the  municipality  of  President  Prudente  on  January 12,  2001, 
seeking  (i) a  declaration  in  respect  of  its  contractual  right  to  continue  to  render  the  services  under  its 
concession  agreement  in  the  municipality  until  the  formal  legal  rescission  of  the  concession  agreement 
and (ii) the payment of indemnities. The action also sought a declaration that the acts and threats of the 
municipality in connection with its planned expropriation were illegal and abusive.  A judgment has been 
handed down confirming our right to continue to render the services. The decision was appealed, and the 
decision  of  the  appeal  court  is  still  pending.  Under  an  injunction  currently  in  force  until  an 
indemnification is paid, we continue to render services in the municipality of Presidente Prudente.  

In March 2011, we filed a repossession lawsuit against the municipality of Álvares Florence, which 
terminated  our  concession  contract  and  took  possession  of  our  installations.  We  requested  an  interim 
injunction  requiring  (i) the  repossession  of  existing  assets  necessary  for  providing  water  and  sewage 
collection, distribution and treatment services, and (ii) the observation of our contractual right to continue 

117 

 
to render the services under its concession agreement in the municipality until the formal legal rescission 
of the concession agreement.  The lawsuit also requested that the interim injunction be converted into a 
permanent  order.   The  first  instance  court  has  denied  our  injunction  claim,  keeping  the  municipality  in 
charge  of  the  water  and  sewage  collection  services.   The  court  also  denied  our  claim  for  a  permanent 
order to which we filed an appeal which is currently under the review of the trial court.  

In  August 2011,  we  filed  a  repossession  lawsuit  against  the  municipality  of  Macatuba,  which 
terminated our concession contract and took possession of our sewage collection and water installations.  
We  requested  an  interim  injunction  requiring  (i) the  repossession  of  existing  assets  necessary  for 
providing water and sewage collection, distribution and treatment services, and (ii) the observation of our 
contractual  right  to  continue  to  render  the  services  under  its  concession  agreement  in  the  municipality 
until the formal legal rescission of the concession agreement.  The lawsuit also requested that the interim 
injunction be converted into a permanent order.  The first instance court has denied our injunction claim, 
keeping the municipality in charge of the water and sewage collection services.  We await the decision of 
the first instance court on the merits of the claim.   

Tariff-Related Legal Proceedings and Consumer Claims 

As  of  December 31,  2011,  approximately  1,500  lawsuits  had  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  collected  and  those 
tariffs. We have obtained final decisions both in favor and against us in many of these lawsuits, and have 
provisioned R$618.5 million as of December 31, 2011 for those lawsuits for which we have determined 
that the risk of loss is probable. 

The  Association  of  Distinguished  Bars  and  Restaurants  (Associação  de  Bares  e  Restaurantes 
Diferenciados) has initiated several lawsuits to challenge the 10.0% penalty fee we charge on late water 
and  sewage  payments.  In  several  of  these  cases,  trial  courts  have  dismissed  the  lawsuits  based  on  the 
plaintiffs’ lack of standing 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 in the civil courts of the State 
of  São  Paulo.  In  this  civil  public  action,  the  civil  courts  ruled  against  us,  and  we  have  appealed  the 
decision and a decision from the appellate court is still pending. Notwithstanding these legal proceedings, 
we have reduced to 2.0% the penalty fee we charge all of our customers on late bill payments. 

Contractors’ Claims 

Certain  contractors  have  filed  claims  against  us  alleging  damages  and  underpayment  of  inflation 
indexation  adjustments,  monetary  losses  incurred  in  connection  with  introduction  of  the  real  and 
economic  instability  of  the  contract,  among  other  claims.  These  suits  are  being  handled  by  different 
courts, and we have established provisions for them when the expectation of loss is considered probable.  
As of December 31, 2011, we had recorded a provision of R$420.8 million for claims whose likelihood of 
loss is considered probable.  

Other Legal Proceedings 

We  are  a  party  to  several  civil  lawsuits  related  to  indemnities  for  property  damage,  pain  and 
suffering,  and  loss  of  profits  allegedly  caused  to  third  parties.   In  the  year  ended  December 31,  2011, 
there was an increase both in the number of lawsuits with probable and possible risk of loss, arising from 
the  increase  in  lawsuits  and  the  review  of  the  expected  outcomes,  comprising  monetary  adjustment, 
interest and fees.  As of December 31, 2011, we had recorded a provision of R$178.4 million, for claims 
whose likelihood of loss is considered probable. 

The São Paulo State Public Attorney’s Office has filed a public civil action against us seeking (i) to 
ensure  water  supply  in  the  municipality  of  Guarujá  is  within  accepted  levels  of  potability  and  in 
accordance  with  current  legislation;  (ii)  to  require  us  to  start  building  a  water  treatment  station;  (iii)  to 
require us to reimburse fees charged to consumers; and (iv) to require us to pay compensation for physical 
harm and pain and suffering caused by allegedly improper water consumption.  A temporary injunction 
was granted to the São Paulo State Public Attorney’s Office, and we appealed the decision.  Our appeal 
was  rejected  by  the  appellate  court.  We  have  presented  an  answer  to  the  complaint,  and  the  lawsuit  is 
currently  in  the  discovery  phase.   We  have  not  yet  estimated  our  potential  liability  with  respect  to  this 
lawsuit because we currently do not have sufficient information to accurately do so.  We evaluated this 
proceeding as a possible loss.  

118 

 
On  October 29,  2003,  the  São  Paulo  State Public  Attorney’s  Office, on behalf of  the people  of  the 
State  of  São  Paulo,  filed  a  civil  public  action  in  a  trial  court  of  the  State  of  São  Paulo  alleging  that  a 
transfer  to  us  of  ownership  of  the  Alto  Tietê  System  reservoirs  from  the  DAEE  would  be  illegal.   In 
October 2004, the court of first instance handed down its judgment on the civil public action and declared 
the agreement between us, DAEE and the State of São Paulo null and void.  This decision was suspended 
and we, the State Treasury and DAEE appealed the decision. On August 23, 2010, the appeal was denied.  
We have petitioned  for  clarification of  the appeal  court’s decision  and will  seek  to  take  the  case  to the 
Supreme  Court.   The  effects of  the  appeal  court’s decision  will  be  suspended until  the  end of  the  legal 
process.  Our legal counsel has assessed the risk of loss as probable, which would prohibit the transfer of 
the reservoirs in payment of the accounts receivable due from the State.   

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

Dividends and Dividend Policy 

Amounts Available for Distribution 

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

(cid:131)       the legal reserve; and 

(cid:131)       retained earnings for investment reserve. 

We are required to maintain a legal reserve, to which we must allocate 5.0% of net profits for each 
fiscal year until the amount for such reserve equals 20.0% 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 30.0% of our capital.  Net 
losses,  if  any,  may  be  offset  against  the  legal  reserve.   As  of  December  31,  2011,  2010  and  2009  the 
balance  of  our  legal  reserve  was  R$521.2  million,  R$460.0  million  and  R$378.5  million,  respectively, 
which was equal to 8.4%, 7.4% and 6.1%, respectively, of our capital. 

Brazilian Corporate Law also provides for two discretionary allocations of net profits that are subject 
to approval by the shareholders at each annual shareholders’ 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 mandatory distributable amount exceeds the sum of realized net profits in any given year, 
such excess may be allocated to an unrealized revenue reserve.  Under Brazilian Corporate Law, realized 
net profits is defined as the amount of net profits that exceeds the net positive result of equity adjustments 
and profits or revenues from operations with financial results after the end of the next succeeding fiscal 
year. 

Under  Brazilian  Corporate  Law,  any  company  may  authorize  in  its  bylaws  the  creation  of  a 
discretionary reserve.  Bylaws 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  allocations  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  our  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  allocation  until  the 

119 

 
   
shareholders  vote  to  transfer  all  or  a  portion  of  the  reserve  to  capital  or  retained  earnings.   As  of 
December  31,  2011,  2010  and  2009  we  had  an  investment  reserve  of  R$3,408.6  million,  R$2,825.0 
million and R$1,732.1 million, respectively. 

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  Brazilian 
GAAP, which does not differ from IFRS. 

The legal reserve is subject to approval by the shareholder vote at our annual shareholders’ 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 Brazilian GAAP.    

Mandatory Distribution 

Brazilian Corporate Law generally requires that the bylaws of each Brazilian corporation specify a 
minimum  percentage  of  the  amounts  available  for  distribution  by  such  corporation  for  each  fiscal  year 
that must be distributed to shareholders as dividends, also known as the mandatory distributable amount.  
Under our bylaws, the mandatory distributable amount has been fixed at an amount equal to not less than 
25.0% of the amounts available for distribution, to the extent amounts are available for distribution at the 
end of each given fiscal year.  

The mandatory distribution is based on a percentage of adjusted net income, not lower than 25.0%, 
rather  than  a  fixed  monetary  amount  per  share.   Brazilian  Corporate  Law,  however,  permits  a  publicly 
held company, such as us, to suspend the mandatory distribution if the board of directors and the fiscal 
committee report to the shareholders’ meeting that the distribution would be inadvisable in view of the 
company’s financial condition.  The suspension is subject to the approval of holders of common shares.  
In this case, the board of directors must file a justification for such suspension with the CVM.  Profits not 
distributed by virtue of the suspension mentioned above shall be attributed to a special reserve and, if not 
absorbed  by  subsequent  losses,  must  be  paid  as  dividends  as  soon  as  the  financial  condition  of  such 
company permits such payments. 

Payment of Dividends 

We  are  required  by  Brazilian  Corporate  Law  and  by  our  bylaws  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  when  profits  were  accrued.   The 
decision to distribute annual dividends is based on the financial statements prepared for the relevant fiscal 
year.   Under  Brazilian  Corporate  Law,  dividends  generally  are  required  to  be  paid  within  60  days 
following the date the dividend was declared, unless a shareholders’ resolution sets forth another date for 
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  on  shareholders’  equity  as  described  under  “—Record  of  Dividend  Payments  and 
Interest  on  Shareholders’  Equity”)  distributed  on  his  or  her  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 us. 

Our bylaws allow us to pay interim dividends from preexisting and accumulated profits related to the 

current or preceding fiscal year. 

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 Unibanco S.A., as the 
custodian and agent for the depositary, which is the registered owner of the common shares underlying 
the ADSs.  Our current registrar is Banco Itaú Unibanco S.A.  The depositary electronically registers the 
common  shares  underlying  the  ADSs  with  the  Central  Bank  and,  therefore,  is  able  to  have  dividends, 
sales  proceeds  or  other  amounts  with  respect  to  these  shares  eligible  to  be  remitted  outside  Brazil. See 
“Item 10.D. Exchange Controls.” 

Payments of cash dividends and distributions, if any, will be made in Brazilian reais to the custodian 
on behalf of the depositary, which will then convert such proceeds into U.S. dollars and will cause such 

120 

 
U.S.  dollars  to  be  delivered  to  the  depositary  for  distribution  to  holders  of  ADSs.   See  “Item 10.D. 
Additional Information—Exchange Controls.”  Under current Brazilian law, dividends generally paid to 
shareholders who are not Brazilian residents, including holders of ADSs, will not be subject to Brazilian 
withholding income tax, except for dividends declared based on profits generated prior to December 31, 
1995.  See “Item 10.E. 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  of  December 26,  1995,  as 
amended.  The rate at which tax-deductible interest may be paid is limited to the product of the average 
TJLP and shareholders’ equity during the relevant period and cannot exceed the greater of:   

(cid:131) 50.0% 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; or

(cid:131) 50.0% of earnings reserves and 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  15.0%  or 
25.0%  if  the  beneficiary  is  resident  in  a  tax  haven.   See  “Item 10.E.  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.   

Dividends and interest on shareholders’ equity over the minimum established in a company’s bylaws 
are  recognized  when  approved  by  the  shareholders  in  the  general  meeting.   Consequently,  the  amounts 
recognized as of December 31, 2011, correspond to the minimum established by law of 25.0% of the net 
profit and the difference was recorded on April 23, 2012 totaling R$ 578.7 million. 

Distributions of dividends 

The  following  table  sets  forth  the  distributions  of  dividends  that  we  made  to  our  shareholders  in 
respect of our 2009, 2010 and 2011 earnings.  All these amounts distributed or to be distributed were or 
will be in the form of interest on shareholders’ equity.

Dividend Policy 

We  intend  to  declare  and  pay  dividends  and/or  interest  on  shareholders’  equity,  as  required  by 
Brazilian Corporate Law and our bylaws.  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.

ITEM 9.        THE OFFER AND LISTING 
A.    Offer and Listing Details 

Market Price of Common Shares  

Our  common  shares  have  been  listed  on  the  BM&FBOVESPA  under  the  symbol  “SBSP3”  since 
June 4, 1997 and, starting on April 24, 2002, have been included in the  Novo Mercado segment of that 
exchange.  As of December 31, 2011, we had 2,767 registered holders of common shares. 

On April 30, 2007, our shareholders approved a reverse stock split of 125 common shares into one 
common  share.   IFRS  requires  the  retroactive  restatement  of  earnings-per-share  computations  for  stock 
dividends, stock splits, and reverse splits. 

The table below sets forth, for the periods indicated, the reported high and low closing sale prices in 
reais  for  common  shares on  the  BM&FBOVESPA.  The  table  also  sets  forth prices per ADS  assuming 
that  ADSs  had  been  outstanding  on  all  such  dates  and  translated  into  U.S.  dollars  at  the  commercial 
market rate for the sale of U.S. dollars for each of the respective dates of such quotations.  In addition, the

C.    Markets 

Trading on the Brazilian Stock Exchanges  

The BM&FBOVESPA stock and futures exchange is a corporation where all stock and futures trades 
in Brazil are carried out, with the exception of public-debt bonds, which are traded electronically, and the 
privatization auctions, which are run by the Rio de Janeiro Stock Exchange. 

Trading on the BM&FBOVESPA is limited to brokerage firms and is conducted between 10:00 a.m. 
and  5:00 p.m.,  or  between  11:00 a.m.  and  6:00 p.m.  during  daylight  savings  time  in  Brazil.   The 
BM&FBOVESPA  also  permits  trading  from  5:45 p.m.  to  7:00 p.m.,  or  between  6:45 p.m.  to  7:30 p.m. 
during daylight savings time in Brazil, during a different trading period of time, called the “after market.”  
Trading on the after market is subject to regulatory limits on price volatility and on the volume of shares 
transacted through Internet brokers. 

In  order  to  maintain  better  quality  control  over  the  fluctuation  of  its  index,  BM&FBOVESPA  has 
adopted a “circuit breaker” system pursuant to which trading sessions are suspended for a period of 30 
minutes  or  an  hour  whenever  the  BM&FBOVESPA  index  falls  below  the  limits  of  10.0%  or  15.0%, 
respectively, in relation to the index at the closing of the previous trading session. 

BM&FBOVESPA settles the sale of shares three business days after they have taken place, without 
monetary adjustment of the purchase price.  The shares are paid for and delivered through a settlement 
agent affiliated with the BM&FBOVESPA.  The BM&FBOVESPA performs multilateral compensation 
for  both  the  financial  obligations  and  the  delivery  of  shares.   According  to  the  BM&FBOVESPA’s 
regulations,  financial  settlement  is  carried  out  by  the  Central  Bank’s  reserve  transfer  system.   The 
securities are transferred by the BM&FBOVESPA’s custody system.  Both delivery and payment are final 
and irrevocable. 

123 

 
   
   
  
   
  
   
  
   
  
Trading on the BM&FBOVESPA is significantly less liquid than trading on the NYSE or other major 
exchanges  in  the  world.   Although  any  of  the  outstanding  shares  of  a  listed  company  may  trade  on the 
BM&FBOVESPA, in most cases fewer than half of the listed shares are actually available for trading by 
the public, the remainder being held by a controlling group or by government entities.  As of the end of 
2011,  the  BM&FBOVESPA  had  a  total  market  capitalization  of  approximately  US$1.2  billion  (R$2.3 
billion)  and  an  average  daily  trading  volume  of  US$3.9  billion  (R$6.2  billion).   The  top  ten  stocks  in 
terms  of  2011  trading  volume  accounted  for  approximately  47.2%  of  all  shares  traded  on  the 
BM&FBOVESPA as of December 31, 2011.  As of December 31, 2011, we accounted for approximately 
0.5% of the market capitalization of all listed companies on BM&FBOVESPA. 

Trading on the BM&FBOVESPA by a holder not deemed to be domiciled in Brazil for Brazilian tax 
and  regulatory  purposes,  or  a  “non-Brazilian  holder,”  is  subject  to  certain  limitations  under  Brazilian 
foreign  investment  regulations.   With  limited  exceptions,  non-Brazilian  holders  may  trade  on  Brazilian 
stock exchanges in accordance with the requirements of CMN Resolution No. 2,689, which requires that 
securities held by non-Brazilian holders be maintained in the custody of financial institutions authorized 
by  the  Central  Bank  and  by  the  CVM  or  in  deposit  accounts  with  financial  institutions.   In  addition, 
Resolution No. 2,689 requires non-Brazilian holders to restrict their securities trading to transactions on 
the  BM&FBOVESPA  or  qualified  over-the-counter  markets.   With  limited  exceptions,  non-Brazilian 
holders  may  not  transfer  the  ownership  of  investments  made  under  Resolution  No. 2,689  to  other 
non-Brazilian  holders  through  a  private  transaction.   See  “Item 10.E.  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. 

The Novo Mercado Segment 

Since  April 24,  2002,  our  common  shares  have  been  listed  on  the  Novo  Mercado  segment  of  the 
BM&FBOVESPA.  The Novo Mercado is a listing segment 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  required  under  Brazilian  law.   A  company  in  the 
Novo  Mercado  must  follow  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  bylaws  to  comply  with  the  Novo 
Mercado requirements.  In addition, the Novo Mercado provides for the creation of a Market Arbitration 
Chamber for conflict 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: 

(cid:131)  maintain only voting shares; 

 (cid:131)  hold public offerings of shares in a manner favoring diversification of the company’s shareholder 

base and broader access to retail investors;

 (cid:131)  maintain a minimum free float of at least 25.0% of the outstanding capital stock of the company;

 (cid:131)  grant tag along rights for all shareholders in connection with a transfer of control of the company;

 (cid:131) limit the term of all members of the board of directors to two years; 

 (cid:131) 

ensure that at least 20.0% of the members of the board of directors are independent, as defined 
under the Novo Mercado regulation;

 (cid:131)  prepare annual, including cash flow statements, in compliance with U.S. GAAP or IFRS or 

reconciled from Brazilian GAAP to U.S. GAAP or IFRS;

 (cid:131)  disclose information on a quarterly basis, including share ownership of certain of our employees 

and directors and amount of free float of shares;

124 

 
  
  
   
  
   
  
  
  
  
  
  
  
  
  
  
  
  
 (cid:131)  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) if it elects to delist from the Novo 
Mercado; and 

(cid:131)  make greater disclosure of related party transactions.  

On  May 10,  2011,  the  Novo  Mercado  rules  were  revised  and  currently  establish  the  following 
additional obligations: 

(cid:131) the chairman of the board of directors is prohibited from simultaneously holding the position of 

chief executive officer; 

(cid:131) the board of directors must disclose its opinion on take over proposals within 15 days from the 

presentation of the proposal; and

(cid:131) the company must have a securities purchase policy and a code of ethics. 

Regulation of Brazilian Securities Markets 

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

Under Brazilian Corporate Law, a company is either public (companhia aberta), such as we are, or 
closely held (companhia fechada).  All public companies, including us, are registered with the CVM and 
are subject to reporting requirements.  A company registered with the CVM 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 BM&FBOVESPA 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 CVM 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  BM&FBOVESPA  be  suspended  in 
anticipation  of  a  material  announcement.   Trading  may  also  be  suspended  on  the  initiative  of  the 
BM&FBOVESPA  or  the  CVM,  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 CVM 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 CVM serves as intermediary.  No special application, other than 
registration with the CVM, is necessary for securities of a public company to be traded in this market.  
The CVM 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 BM&FBOVESPA by non-residents of Brazil is subject to limitations under Brazilian 
foreign  investment  and  tax  legislation.   The  Brazilian  custodian  for  our  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 

125 

 
  
  
  
  
        
   
  
      
    
     
   
shares, the holder will be entitled to continue to rely on the custodian’s registration for five business days 
after the exchange.  Thereafter, the holder may not be able to obtain and remit U.S. dollars abroad upon 
the disposition of our common shares, or distributions relating to our common shares, unless the holder 
obtains a new registration.  See “Item 10.D. Exchange Controls.”

B.    Memorandum and Articles of Association 

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

Corporate Purposes 

We are a mixed capital company (sociedade de economia mista) of unlimited duration, incorporated 
on  September 6,  1973,  with  limited  liability,  duly  organized  and  operating  under  Brazilian  Corporate 
Law.  As set forth in Article 2 of our bylaws, our corporate purpose is to render basic sanitation services, 
aimed at the universalization of basic sanitation in the State of São Paulo without harming our long-term 
financial sustainability.  Our activities comprise water supply, sanitary sewage services, urban rainwater 
management and drainage services, urban cleaning services solid waste management services and related 
activities,  including  the  planning,  operation,  maintenance  and  commercialization  of  energy,  and  the 
commercialization of services, products, benefits and rights that directly or indirectly arise from its assets, 
operations  and  activities.   We  are  allowed  to  act,  in  a  subsidiary  form,  in  other  Brazilian  locations  and 
abroad.  

Directors’ Powers 

Although our bylaws contain no specific provisions regarding a director or executive officer’s power 
to  vote  on  a  proposal,  arrangement  or  contract  in  which  that  director  has  a  material  interest,  under 
Brazilian Corporate Law, a director or an executive officer is prohibited from voting in any meeting or 
with respect to any transaction in which that director or executive officer has a conflict of interest with the 
company and must disclose the nature and extent of the conflicting interest to be recorded 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 bylaws, our shareholders are responsible for establishing the compensation we pay to the 

members of our board of directors, members of the fiscal committee and the executive officers. 

Pursuant  to  Brazilian  Corporate  Law,  each member  of  our  board of  directors  must  be a  resident of 

Brazil.  Our bylaws do not establish any mandatory retirement age limit. 

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

Description of Common Shares 

126 

 
General   

Each  common  share  entitles  the  holder  thereof  to  one  vote  at  our  annual  or  special  shareholders’ 
meetings.  Brazilian Corporate Law requires that all our shareholders’ meetings be called by publication 
of a notice in the Diário Oficial do Estado de São Paulo, the official government publication of the State 
of São Paulo, and in a newspaper of general circulation in our principal place of business, currently the 
city of São Paulo, at least fifteen days prior to the meeting.  In addition, the CVM 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 requires the attendance of shareholders, either in person or by 
proxy, representing at least 25.0% of the shares entitled to vote and, on second call, the meetings can be 
held with the attendance of shareholders, also either in person or by proxy, representing any number of 
shares entitled to vote. 

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

In  principle,  a  change  in  shareholder  rights,  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  shareholder  rights,  such  as  the 
creation  of  preferred  shares,  Brazilian  Corporate  Law  requires  the  approval  of  a  majority  of  the 
shareholders who would be adversely affected by the change attending a special meeting called for such 
reason. It should be emphasized, however, that our by-laws expressly prevents us from issuing preferred 
shares. Brazilian  Corporate  Law  specifies  other  circumstances  where  a  dissenting  shareholder  may  also 
have appraisal rights. 

According  to  Brazilian  Corporate  Law,  neither  a  company’s  bylaws  nor  actions  taken  at  a  general 

meeting of shareholders may deprive a shareholder of certain rights, such as: 

 (cid:131) 

 (cid:131) 

 (cid:131) 

 (cid:131) 

 the right to participate in the distribution of profits;

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

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

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

(cid:131) the right to withdraw from the company in the cases specified in Brazilian Corporate Law. 

Pursuant to Brazilian Corporate Law and our bylaws, each of our common shares carries the right to 
one vote at our shareholders’ meetings.  We may not restrain or deny that right without the consent of the 
holders of a majority of the shares affected. 

Neither Brazilian Corporate Law nor our bylaws expressly addresses: 

(cid:131) staggered terms for directors; 

(cid:131) cumulative voting, except as described below; or  

127 

 
  
  
   
  
   
  
  
  
  
  
  
   
  
      
     
     
(cid:131) measures that could prevent a takeover attempt. 

However, under the laws of the State of São Paulo, the State is required to own at least a majority of 

our outstanding common shares. 

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

In  addition,  shareholders  owning  at  least  15.0%  of  the  capital  may  request  the  right  to  elect, 

separately a member of the Board of Directors. 

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 his or her ownership interest in us, except 
in the event of the grant and exercise of any option to acquire shares of our capital stock.  The preemptive 
rights  are  valid  for  a  30-day  period  from  the  publication  of  the  announcement  of  the  capital  increase.  
Shareholders  are  also  entitled  to  sell  this  preemptive  right  to  third  parties.   Under  Brazilian  Corporate 
Law,  we  may  amend  our  bylaws  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 bylaws 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.D. Risk Factors - Risks Relating 
to  Our  Common  Shares  and  ADSs  -  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.” 

Redemption and Rights of Withdrawal 

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

(cid:131) 

(cid:131) 

(cid:131) 

to reduce the mandatory distribution of dividends; 

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

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

(cid:131) to change our corporate purpose; 

(cid:131) 

(cid:131) 

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

 to transform into another type of company; 

128 

 
   
  
  
   
  
  
  
  
  
  
  
  
  
  
  
  
(cid:131) 

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

(cid:131) to acquire control of another company at a price which exceeds the limits set forth in Brazilian 

Corporate Law. 

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

In addition, the rights of withdrawal in the third, fourth and eighth bullet points above  may not be 
exercised by holders of shares if such shares (i) are liquid, defined as being part of the BM&FBOVESPA 
index  or  other  stock  exchange  index  (as  defined  by  the  CVM),  and  (ii) are  widely  held,  such  that  the 
controlling shareholder or companies it controls have less than 50.0% of our shares.  Our common shares 
are included on the BM&FBOVESPA 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 transaction was approved. 

We may cancel the right of withdrawal if the payment amount has a material adverse effect on our 

finances. 

Conversion Right 

Not applicable because our capital stock is only comprised of common shares. 

Especial and General Meetings 

Unlike  the  laws  governing  corporations  incorporated  under  the  laws  of  the  State  of  Delaware,  the 
Brazilian corporation law does not allow shareholders to approve matters by written consent obtained as a 
response to a consent solicitation procedure.  All matters subject to approval by the shareholders must be 
approved in a general meeting, duly convened pursuant to the provisions of Brazilian corporation law.  
Shareholders may be represented at a shareholders’ meeting by attorneys-in-fact who are (i) shareholders 
of the corporation, (ii) a Brazilian attorney, (iii) a member of management or (iv) a financial institution. 

General shareholders’  meetings  may  be  called  by  publication  of  a  notice  in  the  Diário  Oficial  do 
Estado de São Paulo and in a newspaper of general circulation in our principal place of business at least 
15 days prior to the meeting.  Special meetings are convened in the same manner as general shareholders’ 
meetings and may occur immediately before or after a general meeting. 

At duly called and convened meetings, our shareholders are empowered to take any action regarding 
our business.  Shareholders have the exclusive right, during our annual shareholders’ meetings required to 
be hold within 120 days of the end of our fiscal year, to approve our financial statements and to determine 
the allocation of our net income and the distribution of dividends related to the fiscal year immediately 
preceding  the  meeting.   The  members  of  our  board  of  directors  are  generally  elected  at  annual 
shareholders’  meetings.   However,  according  to  Brazilian  corporation  law,  they  can  also  be  elected  at 
extraordinary  shareholders’  meetings.   At  the  request  of  shareholders  holding  a  sufficient  number  of 
shares, a fiscal committee can be established and its members elected at any shareholders’ meeting. 

129 

 
 
     
A special shareholders’ meeting may be held concurrently with the annual shareholders’ meeting and 
at  other  times  during  the  year.   Our  shareholders  may  take  the  following  actions,  among  others, 
exclusively at shareholders’ meetings: 

(cid:131) election and dismissal of the members of our board of directors and our fiscal committee, if the 

shareholders have requested the set up of the latter; 

 (cid:131) 

 approval of the aggregate compensation of the members of our board of directors and board of 
executive officers, as well as the compensation of the members of the fiscal committee, if one 
has been established; 

 (cid:131) 

amendment of our bylaws; 

 (cid:131) 

approval of our merger, consolidation or spin-off; 

 (cid:131) 

 approval of our dissolution or liquidation, as well as the election and dismissal of liquidators and 
the approval of their accounts; 

 (cid:131)   granting stock awards and approval of stock splits or reverse stock splits; 

 (cid:131) 

 (cid:131) 

 (cid:131) 

 (cid:131) 

 (cid:131) 

approval of stock option plans for our management and employees, as well as for the 
management and employees of other companies directly or indirectly controlled by us; 

approval, in accordance with the proposal submitted by our board of directors, of the distribution 
of our net income and payment of dividends;

authorization to delist from the Level 2 of Differentiated Corporate Governance Practices and to 
become a private company, except if the cancellation is due to a breach of the Level 2 regulations 
by management, and to retain a specialized firm to prepare a valuation report with respect to the 
value of our shares, in any such events;

approval of our management accounts and our financial statements;  

approval of any primary public offering of our shares or securities convertible into our shares; 
and 

 (cid:131)  deliberate upon any matter submitted by the board of directors. 

Limitations on Rights to Own Securities 

There are no limitations under Brazilian law and our bylaws on the rights of non-residents or foreign 
shareholders to own securities, including the rights of such non-resident or foreign shareholders to hold or 
exercise voting rights. 

Anti-Takeover Provisions 

Pursuant to article 40 of our bylaws and the Novo Mercado regulations, any party that acquires our 
control  must  extend  a  tender  offer  for the  shares  held  by  non-controlling  shareholders  at  the  same 
conditions  and  purchase  price  paid  to  the  controlling  shareholder.   In  addition,  State  Law  No.  119/73, 
which created our Company, requires the State to hold the majority of our shares at all times.

The  Brazilian  Corporate  Law  provides  that  all  discretionary  allocations  of  “adjusted  income”  are 
subject  to  shareholder  approval  and  may  be  added  to  capital  or  distributed  as  dividends  in  subsequent 
years.   In  the  case  of  our  capital  reserve  and  the  legal  reserve,  they  are  also  subject  to  shareholder 
approval; however, the use of their respective balances is restricted to being added to capital or absorbed 
by losses.  They cannot be used as a source for income distribution to shareholders.  

Capital Reserve   

Our  capital  reserve  is  comprised  of  tax  incentives  and  donations  from  government  agencies  and 
private entities received through December 31, 2007.  As of December 31, 2011, we had a capital reserve 
of R$124.3 million.  

Investment Reserve  

Our  investment  reserve  is  comprised  specifically  of  internal  funds  for  expansion  of  water  and  sewage 
service systems.  As of December 31, 2011, we had an investment reserve of R$3,408.6 million. 

Legal Reserve  

Under Brazilian Corporate Law, we are required to record a legal reserve to which we must allocate 
5% of the adjusted net income each year until the amount of the reserve equals 20.0% of paid-in capital.  
Any accumulated deficit may be charged against the legal reserve.  As of December 31, 2011, the balance 
of our legal reserve was R$521.2 million. 

Arbitration 

In  connection  with  our  listing  with  the  Novo  Mercado  segment  of  the  BM&FBOVESPA,  we,  our 
shareholders,  directors  and  officers  have  undertaken  to  refer  to  arbitration  any  and  all  disputes  or 
controversies  arising  out  of  the  Novo  Mercado  rules  or  any  other  corporate  matters.   See  “Item 9.C. 
Markets.”  Under our bylaws, any dispute among us, our shareholders and our management with respect 
to  the  application  of  Novo  Mercado  rules,  Brazilian  Corporate  Law,  the  application  of  the  rules  and 
regulations regarding Brazilian capital markets, will be resolved by arbitration conducted pursuant to the 
BM&FBOVESPA  Arbitration  Rules  in  the  Market  Arbitration  Chamber.   Any  dispute  among 
shareholders, including holders of ADSs, and any dispute 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. 

C.    Material Contracts 

For  a description of  the  material  contracts  entered  into by  the  State  and us,  see  “Item 7.B.  Related 

Party Transactions—Transactions with the State of São Paulo—Agreements with the State.”  

D.    Exchange Controls  

The right to convert dividend or interest payments and proceeds from the sale of 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,  that  the  relevant  investments  have  been 
registered  with  the  Central  Bank  and  the  CVM.   Such  restrictions  on  the  remittance  of  foreign  capital 
abroad  may  hinder  or  prevent  the  custodian  for  our  common  shares  represented  by  our  ADSs  or  the 
holders of our common shares from converting dividends, distributions or the proceeds from any sale of 
these shares  into  U.S.  dollars  and  remitting  the  U.S.  dollars  abroad.   Holders  of  our  ADSs  could  be 
adversely affected by delays in, or refusal to grant any, required government approval to convert Brazilian 
currency payments on the common shares underlying our ADS and to remit the proceeds abroad. 

Resolution No. 1,927 of the CMN provides for the issuance of depositary receipts in foreign markets 
in  respect  of  shares  of  Brazilian  issuers.   The  ADS  program  was  approved  under  the  Annex  V 
Regulations  by  the  Central  Bank  and  the  CVM  prior  to  the  issuance  of  the  ADSs.   Accordingly,  the 
proceeds  from  the  sale  of  ADSs  by  ADR  holders  outside  Brazil  are  not  subject  to  Brazilian  foreign 
investment  controls,  and  holders  of  the  ADSs  are  entitled  to  favorable  tax  treatment  under  certain 

131 

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

E.    Taxation   

This summary contains a description of certain Brazilian and U.S. federal income tax consequences 

of the purchase, ownership and disposition of common shares or ADSs by a holder. 

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

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 laws and regulations 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 CMN (“2,689 holder”). 

Taxation of Dividends 

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

Taxation of Gains 

Gains  realized  outside  Brazil  by  a  non-Brazilian  holder  on  the  disposition  of  ADSs  to  another 
non-Brazilian  holder  are  not  currently  subject  to  Brazilian  tax.   However,  according  to  certain 
interpretations of 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 definitive judicial court ruling to act as the leading case 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 

132 

 
   
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, 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.   

For Brazilian purposes, as of January 2009, a tax haven is considered a regime: (i) which does not 
impose income tax or does so at a rate of 20% or lower, or (ii) where applicable local legislation imposes 
restrictions on the disclosure of the shareholding composition or the ownership of investments, or on the 
ultimate  beneficiary  of  the  income  derived  from  transactions  carried  out  and  attributable  to  a  non-
Brazilian holder. 

On June 24, 2008, Law No. 11,727 was enacted defining the concept of a “privileged tax regime” in 
connection with transactions subject to transfer pricing and thin capitalization rules.  In this conception, 
privileged tax regimes are more comprehensive than tax havens.  A “privileged tax regime” is considered 
to be a jurisdiction that meets any of the following requirements: (i) which does not tax income or taxes 
income  at  a  maximum  rate  lower  than  20.0%;  (ii)  grants  tax  advantages  to  a  non-resident  entity  or 
individual  (a)  without  requiring  substantial  economic  activity  in  the  jurisdiction  of  such  non-resident 
entity or individual or (b) to the extent such non-resident entity or individual does not conduct substantial 
economic activity in the jurisdiction of such non-resident entity or individual; (iii) does not tax income 
generated abroad, or imposes tax on income generated abroad at a maximum rate lower than 20.0%, or 
(iv)  restricts  the  ownership  disclosure  of  assets  and  ownership  rights  or  restricts  disclosure  about 
economic transactions. 

Notwithstanding  the  fact  that  the  “privileged  tax  regime”  concept  was  enacted  in  connection  with 
Brazilian transfer pricing and thin capitalization rules, there is no assurance that Brazilian tax authorities 
will  not  attempt  to  apply  the  concept  of  privileged  tax  regimes  to  other  types  of  transactions,  such  as 
investments  in  the  Brazilian  financial  and  capital  markets.  We  recommend  that  prospective  investors 
consult  their  own  tax  advisors  from  time  to  time  to  verify  any  possible  tax  consequences  of  Law  No. 
11,727.   

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): 

(cid:131)  are exempt from income tax when assessed by a 2,689 holder and is not a tax haven based holder; 

and 

(cid:131)  are subject to income tax at a rate of 15% in any other case, including gains assessed by a non-
Brazilian holder that (1) is not a 2,689 holder, or (2) is a 2,689 holder but is a tax haven based 
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. 

133 

 
  
      
     
   
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 

According to Brazilian laws and our bylaws, we may opt to distribute income as interest attributed to 

shareholders’ equity as an alternative to the payment of dividends.  

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 based 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 is no Brazilian 
stamp, issue, registration, or similar taxes or duties payable by a non-Brazilian holder of common shares 
or ADSs. 

Tax on Financial Transactions (Imposto sobre Operações Financeiras, or IOF) 

The IOF is a tax on foreign exchange, securities, credit and insurance transactions.  The IOF rate may 
be changed by an Presidential Decree (rather than a law).  In addition, the IOF rate is not subject to the 
ex-post-facto  principle,  which  provides  that  laws  increasing  the  rate  of  or  creating  new  taxes  will  only 
come into effect as of the latter of (i) the first day of the year following their publication, or (ii) ninety 
days after their publication, and therefore, any increase in the IOF rate has an immediate effect.  A statute 
increasing the IOF rate will as a result only take effect from its publication date. 

Although the maximum rate of IOF is 25% for foreign exchange transactions, the inflow and outflow 
of  funds  are  generally  subject  to  IOF  at  a  rate  of  0.38%;  however,  effective  as  of  December  1,  2011, 
exchange  transactions  for  the  inflow  of  funds  in  Brazil  for  investments  made  by  foreign  investors  are 
subject to IOF at a rate of 0% for variable income transactions carried out on the Brazilian stock, futures 
and  commodities  exchanges,  as  well  as  for  acquisitions  of  common  shares  of  Brazilian  publicly-held 
companies in public offerings or subscription of common shares related to capital contributions, provided 
that the company has registered its common shares for trading on the stock exchange. The IOF rate will 
also be 0% for the outflow of funds from Brazil related to these type of investments, including payments 
of  dividends  and  interest  on  shareholders'  equity.   Lastly,  the  0%  rate  also  applies  to  settlements  of 
simultaneous  foreign  exchange  transactions  for  the  cancellation  of  depositary  receipts  transferred  into 
shares traded on the stock exchange.  

The  IOF  may  also  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 assignment of shares 
traded on Brazilian stock exchanges to issue depositary receipts traded abroad is subject to IOF at the rate 

134 

 
of 1.5%. The executive branch, also by a Presidential Decree, may increase the IOF rate by up to 1.5% 
per day, but only with respect to future transactions.  

United States Federal Income Tax Considerations 

The  following  discussion  is  a  summary  of  certain  U.S.  federal  income  tax  consequences  of  the 
acquisition, ownership and disposition of common shares or ADSs as of the date hereof.  This discussion 
applies only to a beneficial owner of common shares or ADSs that is a “U.S. holder”.  As used herein, the 
term “U.S. holder” means a beneficial owner of a common share or ADS that, for U.S. federal income tax 
purposes, is: 

(cid:131) an individual who is a citizen or resident of the United States;

(cid:131) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) 

created or organized in or under the laws of the United States any state thereof or the District of 
Columbia; 

(cid:131) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

(cid:131) a trust if it (1) is subject to the primary supervision of a court within the United States and one or 
more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a 
valid election in effect under applicable U.S. Treasury Department regulations to be treated as a 
U.S. person. 

If a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) 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.   A  U.S.  holder  that  is  a  partner  of  a  partnership  holding 
common shares or ADSs should consult its tax advisors. 

Except where noted, this discussion deals only with common shares or ADSs held as capital assets 
within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the Code, and 
does  not  deal  with  U.S.  holders  that  may  be  subject  to  special  U.S.  federal  income  tax  rules,  such 
as dealers  in  securities  or  currencies,  traders  in  securities  that  elect  to  use  a  mark-to-market  method  of 
accounting  for  their  securities  holdings,  banks  or  other  financial  institutions,  tax-exempt  organizations, 
insurance  companies,  real  estate  investment  trusts,  regulated  investment  companies,  persons  holding 
common shares or ADSs as part of a hedging, integrated, conversion or constructive sale transaction or a 
straddle, persons liable for alternative minimum tax, pass-through entities and investors in a pass-through 
entity, persons owning 10% or more of our voting stock, or persons whose “functional currency” is not 
the U.S. dollar.   

This discussion is based upon the provisions of the Code, and existing and proposed U.S. Treasury 
Department regulations, administrative pronouncements of the Internal Revenue Service, or the IRS, and 
judicial decisions as of the date hereof.  Such authorities may be repealed, revoked or modified so as to 
result  in  U.S.  federal  income  tax  consequences  different  from  those  discussed  below,  possibly  with 
retroactive  effect.   In  addition,  this  discussion  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.  

Except  as  specifically  described  below,  this  discussion  assumes  that  we  are  not  a  passive  foreign 
investment company, or PFIC, for U.S. federal income tax purposes.  Please see the discussion under “—
Passive Foreign Investment Company Rules” below.  Further, this discussion does not address the U.S. 
federal estate and gift, alternative minimum tax, state, local or non-U.S. tax consequences of acquiring, 
holding or disposing of common shares or ADSs. 

ADSs 

In general, for U.S. 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 U.S. federal income tax.  However, the 

135 

 
 
    
 
 
     
 
 
    
 
   
U.S. Treasury Department 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  income  taxes 
described herein could be affected by future actions that may be taken by the U.S. Treasury Department. 

Taxation of Dividends 

The gross amount of distributions paid to a U.S. holder (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  U.S.  federal  income  tax  principles.   Such 
income generally will be includable in a U.S. holder's gross income as ordinary income when actually or 
constructively  received  by  the  U.S.  holder,  in  the  case  of  common  shares,  or  when  actually  or 
constructively received by the Depositary, in the case of ADSs.  Such dividends will not be eligible for 
the dividends received deduction allowed to corporations under the Code.  To the extent that the amount 
of  any  distribution  exceeds  our  current  and  accumulated  earnings  and  profits  for  a  taxable  year,  the 
distribution will first be treated as a tax-free return of capital to the extent of the U.S. holder’s adjusted 
tax  basis  in  the  common  shares  or  ADS,  causing  a  reduction  in  such  adjusted  tax  basis  (and  thereby 
increasing  the  amount  of  gain,  or  decreasing  the  amount  of  loss,  to  be  recognized  on  a  subsequent 
disposition  of  our  common  shares  or  ADSs),  and  thereafter  as  capital  gain  recognized  on  a  sale  or 
exchange.  Because we do not expect to maintain calculations of earnings and profits in accordance with 
U.S. federal income tax principles, U.S. holders should expect that a distribution will generally be treated 
as a dividend for U.S. federal income tax purposes.  Distributions of additional common shares or ADSs 
to  U.S.  holders  that  are  part  of  a  pro  rata  distribution  to  all  of  our  shareholders  generally  will  not  be 
subject to U.S. federal income tax. 

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  the  U.S. 
holder, 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, the U.S. holder will have a tax 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 foreign currency gain or loss that is treated as U.S. source ordinary income or loss.  If 
dividends paid in reais are converted into U.S. dollars on the day they are received by the U.S. holder or 
the  Depositary,  as  the  case  may  be,  U.S.  holders  generally  should  not  be  required  to  recognize  foreign 
currency  gain  or  loss  in  respect  of  the  dividend  income.   U.S.  holders  should  consult  their  own  tax 
advisors  regarding  the  treatment  of  any  foreign  currency  gain  or  loss  if  any  reais  received  by  the  U.S. 
holder or the Depositary or its agent are not converted into U.S. dollars on the date of receipt.   

Certain dividends received by certain non-corporate U.S. holders may be eligible for preferential tax 
rates  so  long  as  (1) specified  holding  period  requirements  are  met,  (2) the  U.S.  holder  is  not  under  an 
obligation  (whether  pursuant  to  a  short  sale  or  otherwise)  to  make  related  payments  with  respect  to 
positions in substantially similar or related property, (3) the company paying the dividend is a “qualified 
foreign corporation” and (4) the company is not a PFIC for U.S. federal income tax purposes, 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 for the current taxable year.  We generally will be treated 
as  a  qualified  foreign  corporation  with  respect  to  our  ADSs  so  long  as  the  ADS  remain  listed  on  the 
NYSE.   Based  on  existing  guidance,  however,  it  is  not  entirely  clear  whether  dividends  received  with 
respect to the common shares (to the extent not represented by ADSs) will be eligible for this treatment, 
because  the  common  shares  are  not  themselves  listed  on  a  U.S.  exchange. U.S.  holders should 
consult their own tax advisors about the application of this preferential tax rate to dividends paid directly 
on common shares.  

Subject  to  certain  complex  limitations  and  conditions  (including  a  minimum  holding  period 
requirement),  Brazilian  income  taxes  withheld  on  dividends,  if  any,  may  be  treated  as  foreign  income 
taxes eligible for credit against a U.S. holder’s U.S. federal income tax liability.  Alternatively, at a U.S. 
holder’s election if it does not elect to claim a foreign income tax credit for any foreign taxes paid during 
the taxable year, all foreign income taxes paid may instead be deducted in computing such U.S. holder’s 
taxable income.  For purposes of calculating the foreign tax credit, dividends paid on our common shares 
will be treated as income from sources outside the United States.  For the purposes of the U.S. foreign tax 
credit  limitations,  the  dividends  paid  by  us  should  generally  constitute  “passive  category  income”  for 

136 

 
most  U.S. holders. The  rules  governing  the  foreign  tax  credit  are  complex. U.S.  holders should 
consult their  tax  advisors  regarding  the  availability  of  the  foreign  tax  credit  under their  particular 
circumstances. 

Taxation of Capital Gains 

For U.S. federal income tax purposes, a U.S. holder generally will recognize taxable gain or loss on 
any  sale,  exchange  or  other  taxable  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 the 
U.S. holder's adjusted tax basis in the common share or ADS, determined in U.S. dollars.  Such gain or 
loss will generally 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 taxable disposition the U.S. holder has held our common shares or 
ADSs for more than one year.  Capital gains of individuals derived with respect to capital assets held for 
more than one year are eligible for reduced rates of taxation.  The deductibility of capital losses is subject 
to limitations.  Any gain or loss recognized by a U.S. holder will generally be treated as U.S. source gain 
or loss.  Consequently, a U.S. holder may not be able to use the foreign tax credit arising from Brazilian 
income  tax  imposed,  if  any,  on  the  disposition  of  a  common  share  or  ADS  unless  such  credit  can  be 
applied (subject to applicable limitations) against U.S. federal income tax due on other income treated as 
derived from foreign sources.  Although we do not believe that U.S. holders will be entitled to a credit or 
deduction with respect to any IOF tax paid on our common shares (as discussed above in “—Brazilian 
Tax  Considerations—Tax  on  Financial  Transactions  (Imposto  sobre  Operações  Financeiras,  or  IOF)”, 
U.S. holders should, however, be entitled to include the amount of the IOF tax paid as part of their initial 
tax basis in such common shares. 

Passive Foreign Investment Company Rules 

Based upon our current and projected income, assets, activities and business plans, we do not expect 
the common shares or ADSs to be considered shares of a PFIC for our current fiscal year (although the 
determination cannot be made until the end of such fiscal year), and we intend to continue our operations 
in  such  a  manner  that we do  not  expect  to be  classified  as  a  PFIC  in  the  foreseeable future.   However, 
because  the  determination  of  whether  the  common  shares  or  ADSs  constitute  shares  of  a  PFIC  will  be 
based upon the composition of our income, assets and the nature of our business, as well as the income, 
assets and business of entities in which we hold at least a 25% interest, from time to time, and because 
there are uncertainties in the application of the relevant rules, there can be no assurance that the common 
shares  or  ADSs  will  not  be  considered  shares  of  a  PFIC  for  any  fiscal  year.   If  the  common  shares  or 
ADSs  were  shares  of  a  PFIC  for  any  fiscal  year,  U.S.  holders  (including  certain  indirect  U.S.  holders) 
may  be  subject  to  adverse  tax  consequences,  including  the  possible  imposition  of  an  interest  charge on 
gains or “excess distributions” allocable to prior years in the U.S. holder’s holding period during which 
we were determined to be a PFIC.  If we are deemed to be a PFIC for a taxable year, dividends on our 
ADSs  would  not  be  qualified  dividend  income eligible  for preferential  rates  of  U.S.  federal  income 
taxation.  In addition, a U.S. holder that owns common shares or ADSs during any taxable year that we 
are  treated  as  a  PFIC  would  generally  be  required  to  file  IRS  form  8621,  as  well  as  comply  with 
additional  annual  filing  requirements  imposed  under  recently  enacted  legislation.   U.S.  holders  should 
consult  their  own  tax  advisors  regarding  the  application  of  the  PFIC  rules  (including  any  information 
reporting requirements in connection therewith) to the common shares or ADSs.   

Information Reporting and Backup Withholding 

In  general,  information  reporting  requirements  will  apply  to  dividends  in  respect  of  our  common 
shares or ADSs or the proceeds received on the sale, exchange, or redemption of our ADSs, in each case 
to  the  extent  treated  as  being  paid  within  the  United  States  (and  in  certain  cases,  outside  of  the  United 
States)  to a  U.S.  holder unless a  U.S.  holder  establishes  its  status  as  an  exempt  recipient,  and  backup 
withholding  may  apply  to  such  amounts  if the  U.S.  holder  does not  establish its  status  as an  exempt 
recipient or fails to provide a correct taxpayer identification number and certify that such U.S. holder is 
not  subject  to  backup  withholding.  The  amount  of  any  backup  withholding  from  a  payment  to a  U.S. 
holder will  be  allowed  as  a  refund  or  credit  against such  U.S.  holder's U.S.  federal  income  tax  liability 
provided the U.S. holder timely furnishes the required information to the IRS.  

In  addition,  U.S.  holders  should  be  aware  that  recently  enacted  legislation  imposes  new  reporting 
requirements  with  respect  to  the  holding  of  certain  foreign  financial  assets,  including  stock  of  foreign 
issuers which is not held in an account maintained by a financial institution, if the aggregate value of all 

137 

 
of  such  assets  exceeds  US$50,000.   U.S.  holders  should  consult  their  own  tax  advisors  regarding  the 
application of the information reporting rules to our common shares and ADSs and the application of the 
recently enacted legislation to their particular situation.

ITEM 11.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

We are exposed to various market risks—in particular, foreign currency risk and interest rate risk.  
We  are  exposed  to  foreign  currency  risk  because  a  substantial  portion  of  our  financial  indebtedness  is 
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.  For further information on our market risks, see Note 3.1 to our 
consolidated financial statements.

In  the  United  States,  our  common  shares  trade  in  the  form  of  ADS.   Each  ADS  represents  two 
common  shares,  issued  by  The  Bank  of  New  York  Mellon,  as  Depositary  pursuant  to  a  Deposit 
Agreement.  The ADSs commenced trading on the NYSE on May 10, 2002. 

Fees and Expenses 

The following table summarizes the fees and expenses payable by holders of ADRs: 

Persons depositing common shares or ADR holders must
pay: 
US$5.00 (or less) per 100 ADSs (or portion of 100 ADSs)

   For:

Issuance of ADSs, including issuances resulting from 
a distribution of common shares or rights or other 
property 
Cancellation of ADSs for the purpose of withdrawal, 
including if the deposit agreement terminates 

US$0.02 (or less) per ADS (to the extent not prohibited by 
the rules of any stock exchange on which the ADSs are listed 
for trading) 

Any cash distribution to you

A fee equivalent to the fee that would be payable if securities 
distributed to you had been common shares and the shares 
had been deposited for issuance of ADSs 

Distribution of securities distributed to holders of 
deposited securities which are distributed by the 
depositary to ADR holders

US$0.02 (or less) per ADS per calendar year (to the extent 
the depositary has not collected a cash distribution fee of

common share register to or from the name of the 
depositary or its agent when you deposit or withdraw 
common shares

Expenses of the depositary in converting foreign currency to 
U.S. dollars 

Cable, telex and facsimile transmissions (when 
expressly provided in the deposit agreement) 

Expenses of the depositary

Taxes and other governmental charges the depositary or the 
custodian have to pay on any ADR or common share 
underlying an ADR, for example, stock transfer taxes, stamp 
duty or withholding taxes

As necessary

Any charges incurred by the depositary or its agents for 
servicing the deposited securities 

No charges of this type are currently made in the 
Brazilian market

Payment of Taxes  

The depositary may deduct the amount of any taxes owed from any payments to you.  It may also sell 
deposited  securities,  by  public  or  private  sale,  to  pay  any  taxes  owed.   You  will  remain  liable  if  the 
proceeds of the sale are not sufficient to pay the taxes.  If the depositary sells deposited securities, it will, 
if appropriate, reduce the number of ADSs to reflect the sale and pay to you any proceeds, or send to you 
any property, remaining after it has paid the taxes.  

Reimbursement of Fees 

The Bank of New York Mellon, as depositary, has agreed to reimburse us for expenses we incur that 
are related to establishment and maintenance expenses of the ADS program.  The depositary has agreed to 

139 

 
   
  
   
      
  
   
      
  
   
      
  
   
  
   
      
  
   
      
      
   
      
  
   
  
 
  
   
reimburse us for our continuing annual stock exchange listing fees.  The depositary has also agreed to pay 
the standard out-of-pocket maintenance costs for the ADRs, which consist of the expenses of postage and 
envelopes  for  mailing  annual  and  interim  financial  reports,  printing  and  distributing  dividend  checks, 
electronic filing of United States federal tax information, mailing required tax forms, stationery, postage, 
facsimile, and telephone calls.  It has also agreed to reimburse us annually for certain investor relationship 
programs  or  special  investor  relations  promotional  activities.   In  certain  instances,  the  depositary  has 
agreed to provide additional payments to us based on any applicable performance indicators relating to 
the ADR facility.  There are limits on the amount of expenses for which the depositary will reimburse us, 
but the amount of reimbursement available to the Company is not necessarily tied to the amount of fees 
the depositary collects from investors.  

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing 
shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them.  The 
depositary  collects  fees for making  distributions  to  investors by deducting  those fees from  the  amounts 
distributed or by selling a portion of distributable property to pay the fees.  The depositary may collect its 
annual fee for depositary services by deduction from cash distributions or by directly billing investors or 
by  charging  the  book-entry  system  accounts  of  participants  acting  for  them.   The  depositary  may 
generally refuse to provide fee-attracting services until its fees for those services are paid. 

Reimbursement of Fees Incurred in 2011 

From  January 1,  2011  until  December  31,  2011,  the  Company  received  from  the  depositary 
US$484,895.87 for standard out-of-pocket maintenance costs for the ADRs (consisting of the expenses of 
postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend 
checks, electronic filing of U.S. Federal tax information, mailing required tax forms, stationery, postage, 
facsimile,  and  telephone  calls),  any  applicable  performance  indicators  relating  to  the  ADR  facility, 
underwriting fees and legal fees.

a) Disclosure Controls and Procedures. 

We carried out an evaluation under the supervision of and with the participation of our management, 
including our Chief Executive Officer and Chief Financial Officer and Investor Relations Officer, of the 
effectiveness  of  the  design  and  operation  of  our  disclosure  controls  and  procedures,  including  those

As a result of this evaluation, our principal executive officer and principal financial officer concluded 
that our disclosure controls and procedures were both designed and effective at the reasonable assurance 
level  as  of  December 31,  2011,  that  the  information  required  to  be  disclosed  in  our  filings  and 
submissions  under  the  Exchange  Act  is  recorded,  processed,  summarized,  and  reported  within  the  time 
periods  specified  by  the  SEC’s  rules  and  forms,  and  that  this  information  is  accumulated  and 
communicated  to  our  management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer 
and Investor Relations Officer, as appropriate to allow timely decisions regarding required disclosure.

ITEM 16        
A.    Audit Committee Financial Expert 

At  our  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  Jerônimo  Antunes 
qualifies as an “audit committee financial expert” as defined for the purposes of this Item 16A in Item 16 
of Form 20-F.  Jerônimo Antunes is an “independent director” within the meaning of the SEC rules.  

B.    Code of Ethics  

We have adopted a code of business conduct and ethics, as defined in Item 16B of Form 20-F under 
the Exchange Act.  Our code of business conduct and ethics, called Code of Ethics and Conduct, applies 
to all of our employees, including our directors, chief executive officer, chief financial officer and chief 
accounting officer, as well as our suppliers and third-party contractors.  Our Code of Ethics and Conduct 
is available on our web site at http://www.sabesp.com.br at the following location:  Investors Relations – 
Corporate Governance.  If we amend the provisions of our Code of Ethics and Conduct, or if we grant any 
waiver  of  such  provisions,  we  will  disclose  the  amendment  or  waiver  on  our  web  site  at  the  same 
address.   You  can  obtain  copies  of  our  Code  of  Ethics  and  Conduct,  without  charge,  upon  request  to

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 our independent registered public accounting firm.  Our management 
is  required  to  obtain  the  board  of  directors’  approval  before  engaging  an  independent  registered  public 
accounting  firm  to  provide  any  audit  or  permitted  non-audit  services  to  us.   The  Brazilian  Federal  and 

141 

 
   
   
   
   
   
   
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 registered public accounting firm.  As part 
of the bidding process, the independent registered public accounting firm is required to submit proposals, 
and are then selected by us based on certain criteria including technical expertise and cost. 

During 2010 and 2011, PricewaterhouseCoopers Auditores Independentes did not provide non-audit 

services to us.

G.    Corporate Governance 

Significant  Differences  between  our  Corporate  Governance  Practices  and  NYSE  Corporate 
Governance Standards 

We are subject to the NYSE corporate governance listing standards.  As a foreign private issuer, the 
standards applicable to us are considerably different than the standards applied to U.S. listed companies.  
Under the NYSE rules, we are required only to:  (a) have an audit committee or audit board, pursuant to 
an applicable exemption available to foreign private issuers, that meets certain requirements, as discussed 
below,  (b) provide  prompt  certification  by  our  chief  executive  officer  of  any  material  non-compliance 
with  any  corporate  governance  rules,  and  (c) provide  a  brief  description  of  the  significant  differences 
between our corporate governance practices and the NYSE corporate governance practice required to be 
followed by U.S. listed companies.  The discussion of the significant differences between our corporate 
governance practices and those required of U.S. listed companies follows below. 

Majority of Independent Directors 

The  NYSE  rules  require  that  a  majority  of  the  board  must  consist  of  independent  directors.  
Independence is defined by various criteria, including the absence of a material relationship between the 
director and the listed company.  Brazilian law does not have a similar requirement.  Under Brazilian law, 
neither our board of directors nor our management is required to test the independence of directors before 
their election to the board.  However, both the Brazilian Corporate Law and the CVM have established 
rules that require directors to meet certain qualification requirements and that address the compensation 
and duties and responsibilities of, as well as the restrictions applicable to, a company’s executive officers 
and directors.  Our board of directors must have a minimum of five members and 20% of the board (even 
if the board consists of greater than five members) must be independent as defined under Novo Mercado 
Regulations.  Currently, three of our ten directors are independent, pursuant to the Novo Mercado Listing 
Regulations.   We  believe  these  rules  provide  adequate  assurances  that  our  directors  are  independent; 
however,  they  do  not  require  that  we  have  a  majority  of  independent  directors,  as  required  under  the 
NYSE rules. 

Executive Sessions 

NYSE rules require that the non-management directors must meet at regularly scheduled executive 
sessions without management present.  The Brazilian Corporate Law does not have a similar provision.  
According to the Brazilian Corporate Law, up to one-third of the members of the board of directors can 
be  elected  from  management.   There  is  no  requirement  that  non-management  directors  meet  regularly 
without  management.   Our  chairperson  and  Chief  Executive  Officer  is  a  member  of  our  board  of 
directors.   All  other  members  of  our  Board  of  Directors  meet  the  NYSE’s  definition  of  “non-
management” directors.  The non-management directors on our board do not typically meet in executive 
session.  Our board of directors consists of ten non-management directors.

Fiscal Committee 

Under  the  Brazilian  Corporate  Law,  the  Conselho  Fiscal,  or  fiscal  committee,  is  a  corporate  body 
independent  of  management  and  a  company’s  external  auditors.   The  fiscal  committee  may  be  either 
permanent  or non-permanent,  in  which  case  it  is  appointed  by  the  shareholders  to  act  during  a  specific 
fiscal  year.   A  fiscal  committee  is  not  equivalent  to,  or  comparable  with,  a  U.S. audit  committee.   The 
primary  responsibility  of  the  fiscal  committee  is  to  review  management’s  activities  and  a  company’s 
financial statements, and to report its findings to a company’s shareholders.  The Brazilian Corporate Law 
requires fiscal committee members to receive as remuneration at least 10% of the average annual amount 
paid to a company’s executive officers.  The Brazilian Corporate Law requires a fiscal committee to be 
composed of a minimum of three and a maximum of five members and their respective alternates. 

Under the Brazilian Corporate Law, the fiscal committee may not contain members that (i) are on our 
board  of  directors,  (ii) are  on  the  board  of  executive  officers,  (iii) are  employed  by  us  or  a  controlled 
company, or (iv) are spouses or relatives of any member of our management, up to the third degree. 

Our  fiscal  committee  consists  of  five  members  and  five  alternates  and  the  members  meet  once  a 

month. 

Audit Committee 

NYSE rules require that listed companies have an audit committee that (i) is composed of a minimum 
of  three  independent  directors  who  are  all  financially  literate,  (ii) meets  the  SEC  rules  regarding  audit 
committees  for  listed  companies,  (iii) has  at  least  one  member  who  has  accounting  or  financial 
management  expertise  and  (iv) is  governed  by  a  written  charter  addressing  the  committee’s  required 
purpose and detailing its required responsibilities.  However, as a foreign private issuer, we need only to 
comply with the requirement that the audit committee meet the SEC rules regarding audit committees for 
listed companies to the extent compatible with Brazilian Corporate Law.  Our audit committee, which is 
not  equivalent  to,  or  comparable  with,  a  U.S. audit  committee,  provides  assistance  to  our  board  of 
directors  on  matters  involving  accounting,  internal  controls,  financial  reporting  and  compliance.   The 
audit committee recommends the appointment of our independent auditors to our board of directors and 
reviews  the  compensation  of  our  independent  auditors  and  helps  coordinate  their  activities.   It  also 
evaluates the effectiveness of our internal financial and legal compliance controls.  The audit committee 
comprises  three  members  elected  by  the  board  of  directors  for  a  one-year  term  with  the  right  to  re-
election, all three of which are independent.  The current members of our audit committee are Jerônimo 
Antunes,  Reinaldo  Guerreiro  and  Heraldo  Gilberto  de  Oliveira.   All  members  meet  the  independent 
membership requirements of the SEC and NYSE as well as other NYSE requirements.  Jerônimo Antunes 
is  the  committee’s  “financial  expert”  within  the  scope  of  the  SEC  rules  covering  the  disclosure  of 
financial experts on audit committees in periodic filings pursuant to the U.S. Securities Exchange Act of 
1934.   

Nomination/Corporate Governance and Compensation Committees 

NYSE rules require that listed companies have a nominating/corporate governance committee and a 
compensation committee composed entirely of independent directors and governed by a written charter 
addressing  the  committee’s  required  purpose  and  detailing  its  required  responsibilities.   Required 
responsibilities  for  the  nominating/corporate  governance  committee  include,  among  other  things, 
identifying and selecting qualified board member nominees and developing a set of corporate governance 
principles applicable to the company.  Required responsibilities for the compensation committee include, 
among  other  things,  reviewing  corporate  goals  relevant  to  the  chief  executive  officer’s  compensation, 
evaluating 
the  chief  executive  officer’s 
compensation levels and recommending to the board non-chief executive officer compensation, incentive-
compensation and equity-based plans. 

the  chief  executive  officer’s  performance,  approving 

We  are  not  required  under  applicable  Brazilian  law  to  have  a  nomination/corporate  governance 
committee or compensation committee.  Under the Brazilian Corporate Law, the total amount available 
for compensation of our directors and executive officers and for profit-sharing payments to our executive 
officers is established by our shareholders at the annual general meeting.  The board of directors is then 
responsible for determining the individual compensation and profit-sharing of each executive officer, as 
well  as  the  compensation  of  our  board  and  committee  members.   In  making  such  determinations,  the 

143 

 
board reviews the performance of the executive officers, including the performance of our chief executive 
officer, who typically excuses himself from discussions regarding his performance and compensation. 

Shareholder Approval of Equity Compensation Plans 

NYSE  rules  require  that  shareholders  be  given  the  opportunity  to  vote  on  all  equity  compensation 
plans  and  material  revisions  thereto,  with  limited  exceptions.  We  do  not  currently  have  any  equity 
compensation  plan.   If  such  a  plan  were  to  be  implemented,  there  is  no  requirement  under  Brazilian 
Corporate Law for the plan to be approved by our shareholders.  However, if the issuance of new shares 
in connection with any equity compensation plan exceeded the authorized capital under our bylaws, the 
increase in capital would require shareholder approval. 

Corporate Governance Guidelines 

NYSE  rules  require  that  listed  companies  adopt  and  disclose  corporate  governance  guidelines.  We 
are in compliance with the adoption of corporate governance provisions and guidelines required under the 
Novo  Mercado  Regulations.   Additionally,  under  the  CVM’s  guidelines,  we  have  established  (i)  the 
Policy of Publicizing Acts or Relevant Facts and the Preservation of Confidentiality which requires us to 
publicly  disclose  all  relevant  information  and  (ii)  the  Securities  Negotiation  Policy  which  requires 
management to inform the CVM and the BM&FBOVESPA of any purchases or sales of our securities.  
We believe the corporate governance guidelines applicable to us under the Novo Mercado Regulations, as 
well as the CVM, do not conflict with the guidelines established by the NYSE. Our corporate governance 
guidelines  and  practices  are  available  in  our  website  at  www.sabesp.com.br  and  in  our  annual 
management report. 

Code of Business Conduct and Ethics 

NYSE rules require that listed companies adopt and disclose a code of business conduct and ethics 
for  directors,  officers  and  employees,  and  promptly  disclose  any  waivers  of  the  code  for  directors  or 
executive  officers.  Applicable  Brazilian  law  does  not  have  a  similar  requirement.  We  have  decided  to 
adopt and disclose a code of ethics and conduct applicable to all our officers, directors and employees.  
The  adoption  and  disclosure  of  a  formal  code  is  not  required  under  the  Brazilian  Corporate  Law.   We 
believe our formal code addresses the matters required to be addressed by the applicable NYSE and SEC 
rules.    

Internal Audit Function 

NYSE rules require that listed companies maintain an internal audit function to provide management 
and  the  audit  committee  with  ongoing  assessments  of  the  company’s  risk  management  processes  and 
system of internal control.  Our internal audit department is under the supervision of our Chief Executive 
Officer and our audit committee and is responsible for our compliance with the requirements of Section 
404  of  the  U.S. Sarbanes  Oxley  Act  of  2002  regarding  internal  control  over  financial  reporting.   Our 
internal audit department reports to our chief executive officer and the audit committee.

Management Report on Internal Control over Financial Reporting 

The management of Companhia de Saneamento Básico do Estado de São Paulo - SABESP ("Company” or 
“SABESP") is responsible for establishing and maintaining effective internal control over financial 
reporting and for its assessment of the effectiveness of internal control over financial reporting as defined 
in Rules 13a-15(f) under the U.S. Exchange Act Rule. 

The Company's internal control over financial reporting is a process designed by, or under the supervision 
of, the Company's Chief Executive Officer and Chief Financial Officer and effected by the Company's Board 
of Directors, Audit Committee, management, and other personnel to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external 
purposes in accordance with generally accepted accounting principles. The Company's internal control 
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of 
records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the 
assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to 
permit preparation of financial statements in accordance with generally accepted accounting principles, 
and that receipts and expenditures of the Company are being made only in accordance with authorizations 
of management and directors of the Company; and (3) provide reasonable assurance regarding prevention 
or timely detection of unauthorized acquisition, use, or disposition of the Company's assets that could have 
a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
material misstatements on a timely basis. Therefore even those systems determined to be effective can 
provide only reasonable assurance with respect to financial statement preparation and presentation. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may 
become inadequate because of changes in conditions, or that the degree of compliance with the policies or 
procedures may deteriorate. 

Management assessed the effectiveness of the Company's internal control over financial reporting as of  
December 31, 2011, based on the criteria established in Internal Control - Integrated Framework issued by 
the Committee of Sponsoring Organizations of the Treadway Commission - COSO. Based on that 
assessment, management has concluded that as of December 31, 2011, the Company's internal control over 
financial reporting is effective. As a result of this evaluation, the principal executive officer and principal 
financial officer of the Company concluded that its disclosure controls and procedures were both designed 
and effective at the reasonable assurance level as of December 31, 2011. 

The effectiveness of the Company's internal control over financial reporting as of December 31, 2011 has 
been audited by PricewaterhouseCoopers Auditores Independentes, an independent registered public 
accounting firm, as stated in their report which appears herein.

Report of Independent Registered Public Accounting Firm  

To the Board of Directors and Shareholders of  
Companhia de Saneamento Básico do Estado de São Paulo - SABESP 

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of 
income, of changes in equity and of cash flows present fairly, in all material respects, the financial position 
of Companhia de Saneamento Básico do Estado de São Paulo - SABESP at December 31, 2011 and 
December 31, 2010, and the results of its operations and its cash flows for each of the three years in the 
period ended December 31, 2011 in conformity with International Financial Reporting Standards as issued 
by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2011, based on 
criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). The Company's management is responsible for these 
financial statements, for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying 
Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express 
opinions on these financial statements and on the Company's internal control over financial reporting 
based on our integrated audits. We conducted our audits in accordance with the standards of the Public 
Company Accounting Oversight Board (United States) and International Standards of Auditing. Those 
standards require that we plan and perform the audits to obtain reasonable assurance about whether the 
financial statements are free of material misstatement and whether effective internal control over financial 
reporting was maintained in all material respects. Our audits of the financial statements included 
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, and evaluating 
the overall financial statement presentation. Our audit of internal control over financial reporting included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based 
on the assessed risk. Our audits also included performing such other procedures as we considered 
necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external 
purposes in accordance with generally accepted accounting principles. A company’s internal control over 
financial reporting includes those policies and procedures that (i) pertain to the maintenance of records 
that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the 
company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that 
receipts and expenditures of the company are being made only in accordance with authorizations of 
management and directors of the company; and (iii) provide reasonable assurance regarding prevention or 
timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a 
material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk 
that controls may become inadequate because of changes in conditions, or that the degree of compliance 
with the policies or procedures may deteriorate.

1                     Operations  

Companhia de Saneamento Básico do Estado de São Paulo ("SABESP" or the "Company") is a 
mixed-capital company headquartered in São Paulo, controlled by the São Paulo State 
Government. The Company is engaged in the provision of basic and environmental sanitation 
services in the State of São Paulo, and supplies treated water on a wholesale basis. 

In  addition  to  providing  basic  sanitation  services  in  the  State  of  São  Paulo,  SABESP  may 
perform  these  activities  in  other  states  and  countries,  and  can  operate  in  drainage,  urban 
cleaning,  solid  waste  handling  and  energy  markets.  The  objective  set  in  the  new  vision  of 
SABESP is to be recognized as the company that ensured universal access to water and sewage 
services  in  its  marketplace,  focused  on  the  customer,  and  in  a  sustainable  and  competitive 
manner, with excellence in environmental solutions. 

On December 31, 2011, the company operates water and sewage services in 363 of municipalities 
of the State of São Paulo, having temporarily discontinued operations in the municipalities of 
Araçoiaba da Serra, Iperó, Cajobi, Alvaro Florense and Macatuba, due to judicial orders under 
ongoing lawsuits. Most of these municipalities operations are based on 30-year concession 
agreements. As of December 31, 2011, 99 concessions had expired and are being negotiated. 
From 2012 to 2033, 39 concessions will expire, and the remaining concessions operate on 
rollover basis. These concessions with indefinite terms and expired concessions under 
negotiation are amortized over the useful lives of the underlying assets. By December 31, 2011, 
the concession program contracts signed totaled 225 (2010 - 201 concession program 
contracts).  

Management believes that all concessions expired and not yet renewed will result in new 
contracts or contract extensions. Therefore, the risk of discontinuity in the provision of 
municipal water supply and sewage services was considered remote by Management. As of 
December 31, 2011, the carrying amount of the underlying assets used in the 99 concessions of 
the municipalities under negotiation totaled R$ 6,588 million which represents 32.44% of the 
total intangible assets and the related gross revenue for the year then ended totaled R$ 2,513 
million which represents 23.87% of the total gross revenue. 

The Company's operations are concentrated in the municipality of São Paulo, which represents 
55.1% of the gross revenues in 2011 (54.7% in 2010).  

On June 23, 2010, the State of São Paulo, the Municipality of São Paulo and the Company 
signed an agreement to share the responsibility for water supply and sewage services to the 
Municipality of São Paulo based on a 30-year concession agreement. This agreement is 
extendable for another  30 years. This agreement sets forth SABESP as the exclusive service 
provider and designates Agência Reguladora de Saneamento e Energia  (“ARSESP”) as 
regulator, establishing prices, controlling and monitoring services.  

Also, on June 23, 2010, the State of São Paulo, the city of São Paulo and SABESP signed the 
“Public service provision agreement of water supply and sewage services”, a 30-year concession 
agreement which is extendable for another 30 years. This agreement involves the following 
activities: 

(i)  protection of the sources of water in collaboration with other agencies of the State and 

the City; 

(ii)  capture, transport and treat of water; 
(iii) collect, transport, treatment and final dispose of  sanitary sewage; and 
(iv) adoption of other actions of basic and environmental sanitation.

Amounts in thousands of reais, unless otherwise indicated 

In the municipality of Santos, in the Baixada Santista region, which has a significant population, 
the Company operates under an authorization by public deed, a situation similar to other 
municipalities in that region and in the Ribeira valley, where the Company started to operate 
after the merger of the companies that formed it.  

On January 5, 2007, Law 11,445 was enacted, establishing the basic sanitation regulatory 
framework, providing for the nationwide guidelines and basic principles for the provision of 
such services, such as social control, transparency, the integration authority of sanitation 
infrastructure, water resources management, and the articulation between industry policies and 
public policies for urban and regional development, housing, suppression of poverty, promotion 
of health and environmental protection, and other related issues.  

The Company's shares have been listed in the Novo Mercado (New Market) segment of 
BM&FBOVESPA (the São Paulo Stock Exchange) since April 2002 and on the New York Stock 
Exchange (NYSE) as American Depositary Receipts (“ADRs”) since May 2002. 

Since 2008, the Company has been entering in joint venture with other companies, resulting in 
the following companies: Sesamm, Águas de Andradina, Saneaqua Mairinque, Aquapolo 
Ambiental, Águas de Castilho e Attend Ambiental. However, SABESP is not the majority 
stockholder of those companies and the agreement of stockholder consider a power of veto and 
a quality vote to SABESP, in some subjects, with others stockholders, indicating join control in 
strategic decisions over those companies. Those companies are considered “joint controlled 
entities” according to IAS 31. 

These financial statements were approved by the Board of Directors on March 22, 2012. 

2                    Summary of Significant Accounting Practices  

2.1               Basis of preparation 

The consolidated financial statements of the Company have been prepared in compliance with 
International Financial Reporting Standards ("IFRS"), issued by the International Accounting 
Standards Board ("IASB"). These policies have been consistently applied to all the years 
presented. 

The financial statements have been prepared under the historical cost except for certain 
financial instruments which were measured at fair value according to IFRS. 

The preparation of financial statements in conformity with IFRS requires the use of certain 
critical accounting estimates. It also requires management to exercise its judgment in the 
process of applying the Company's accounting policies. The areas involving a higher degree to 
judgment or complexity, or areas where assumptions and estimates are significant to the 
consolidated financial statements are described in Note 4. 

2.2              Proportional consolidation 

The consolidated financial statements include the financial statements of the Company and its 
investees: Sesamm – Serviços de Saneamento de Mogi Mirim S/A, Águas de Andradina S.A., 
Saneaqua Mairinque S.A., Aquapolo Ambiental S.A., Attend Ambiental e Águas de Castilho, 
which were proportionally consolidated according to the equity interest in these investees.  

The Company has no majority shares of its investees, but according to investees’  By-Laws 
approvals of any subject by shareholders in general meeting, except for the approval of any 
subject mentioned in the investees’  By-Laws, which relates to decisions that affect financial and

operational policies, for example, approval of the business plan, will be made by a majority vote, 
and SABESP has power of veto. 

For the purposes of calculating the Company's proportional share of revenues, expenses, assets 
and liabilities of its investees, unrealized gains or transactions between the Company and its 
investees were eliminated in proportion to the Company's interest; unrealized losses are also 
eliminated, unless the transaction presents evidence of impairment of the transferred asset. The 
accounting policies applied by the investees are consistent with the accounting policies adopted 
by the Company.

2.4              Translation into foreign currency 

(a)         Functional and reporting currency 

Items included in the financial statements are measured using the currency of the primary 
economic environment in which the company operates ("the functional currency"). The financial 
statements are presented in Brazilian reais  (R$ or reais), which is also the Company's 
functional and presentation currency. All financial information presented has been presented in 
reais, except where indicated. 

(b)         Foreign currency translation 

Foreign currency-denominated transactions are translated into Brazilian reais  using the 
exchange rates prevailing at the transaction dates. Balance sheet accounts are translated at the 
exchange rate  prevailing at balance sheet date. Exchange gains and losses arising on the 
settlement of these transactions and the translation of foreign currency-denominated cash 
assets and liabilities are recognized in Foreign exchange result in the statement of income.  

2.5              Financial Instruments

fair value through profit or loss, loans and receivables, held-to-maturity and available for sale. 
The classification depends on the purpose for which the financial assets were recognized at fair 
value and subsequently acquired. Management determines the classification of the financial 
assets at inception. As of December 31, 2011 and 2010, the Company had no financial assets 
classified in the category held-to-maturity and available for sale.

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

(a)          Financial assets calculated at fair value through profit or loss 

These are financial assets held for active and frequent trading. Financial asset is classified in this 
category if it was acquired to be negotiated in short-term. These assets are classified as current 
assets. Gains or losses arising from changes in the fair value of financial assets measured at fair 
value through profit or loss are presented in the statement of income in 'Financial income' or 
'Financial expenses' in the period they occur, unless the instrument has been contracted in 
connection to another transaction. In this case, changes are recognized in the same line item of 
income affected by this transaction.  

(b)          Loans and receivables 

These comprise receivables which are non-derivative financial assets with fixed or determinable 
payments, not quoted in an active market. Loans and receivables are presented in current assets 
or liabilities, except for those with maturity of more than 12 months after the balance sheet date 
(these are classified as noncurrent assets or liabilities). The Company's loans and receivables 
include cash and cash equivalent trade accounts receivable, other accounts receivable and loans. 
Loans and receivables are recognized at fair value e subsequently recorded at amortized cost, 
under the effective interest rate method. 

2.6              Cash and cash equivalents 

Cash and cash equivalents includes cash in hand, deposits held at call with banks, other short-
term highly liquid investments with original maturities of three month or less.  

2.7              Revenue from sales and services 

a)       Revenue from sales and services 

Revenue from water supply and sewage collection are recognized as the water is consumed and 
services are provided. Revenues, including the revenues unbilled, are recognized at the fair value 
of the consideration received or receivable for the sale of those services in the ordinary course of 
the Company’s activities. Revenue is shown net of value-added tax, rebates and discounts. 
Revenues from unbilled represent incurred revenues in which the services were provided, but 
not yet billed until the end of the each period. Water supply and sewage services are recorded as 
trade accounts receivable based on monthly estimates of the completed services. 

The Company recognizes revenue when: i) products are delivered or services are rendered; ii) 
the amount of revenue can be reliably measured, iii) it is probable that future economic benefits 
will flow to the Company and iv) it is probable that the amounts will be collected. The amount of 
revenue is not considered to be reliably measurable until all conditions relating to the sale have 
been satisfied. Amounts in dispute are recognized as revenue when collected. 

b)       Construction revenue 

Revenue from concession construction contracts is recognized in accordance with IAS 11 
Construction Contracts using the percentage-of-completion method, provided that the 
applicable conditions for application are fulfilled. The percentage of completion is calculated 
from the ratio of the actual costs incurred on the balance sheet date to the planned total costs 
(cost-to-cost method). Revenue is recognized by reference to the construction costs incurred 
during the period plus a fee earned. The fee represents the additional margin related to the work 
performed by the Company in relation to such construction contracts and it is added to the 
construction costs incurred and the total is recognized as construction revenue.

2.8             Customer accounts receivable and allowance for doubtful accounts 

Customer accounts receivable are amounts due from customers for services performed in the 
ordinary course of business. If collection is expected in one year or less, they are classified as 
current assets. If not, they are presented as noncurrent assets.  

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 the analysis of the history of receipts and existing warranties, and it does not expect to 
incur in additional significant losses, mainly in relation to the municipalities.  

2.9              Inventories  

Inventories of supplies for consumption and maintenance of the water and sewage systems are 
stated at the lower of average cost of acquisition or realizable value, and are classified in current 
assets.  

2.10          Investment property 

The investment property is recognized by the cost of acquisition or the construction cost, less 
the related accumulated depreciation. The depreciation is calculated by straight line basis 
considering the useful life of the assets. The maintenance expense is recognized in the profit and 
loss when occurred. 

The Company held some assets for a currently undetermined future use. The Company is 
analyzing whether the assets will be used in the operation or will be sold in short-therm.  

2.11            Property, plant and equipment 

Property, plant and equipment comprise mainly administrative facilities which are not related 
to the concession contracts. Those assets are stated at historical cost of acquisition or 
construction less depreciation, net of impairment charge, when necessary, and include interest 
capitalized incurred during the construction period where applicable, for the qualifying assets.  

Subsequent costs included in the asset's carrying amount or recognized as a separate asset, as 
appropriate, only when it is probable that the future economic benefit associated with the item 
will flow to the Company and the cost of the item can be measured reliably. All other repairs and 
maintenance are charged to the income statement during the financial period in which they 
were incurred. 

Land is not depreciated. Depreciation is calculated using the straight-line method to allocate 
their cost and is described in Note 11(a). 

The residual amount and the useful life of the underlying assets are reviewed and adjusted, if 
necessary, in the end of the year. 

Gain and losses on disposals are determined by comparing the proceeds with the carrying 
amount and are recognized within other operating income (expenses) in the income statements. 

2.12           Intangible assets 

Intangibles are stated at acquisition cost and/or construction of the underlying assets, including 
the construction margin, interest and other financial charges capitalized during the construction 
period, in this case, for the qualifying assets when applicable. Qualifying assets are assets that, 
necessarily, take a substantial period to get ready for its intended use or sale. The Company

considers that substantial period means a period greater than 12 months. This period was 
established by considering the completion period of the majority of its constructions which is 
greater than 12 months. 

The amortization is calculated when the intangible assets are available for use in the necessary 
condition established by the Company. 

The amortization reflects the period over the expected future economic benefits generated by 
the intangible asset and can be the period of the contract or the useful life of the underlying 
assets constructed, what occurs first. 

The amortization of the intangible assets finish when the underlying asset is totally consumed or 
its is alienated, what occurs first. 

Infrastructure to which the operator is given access by the grantor of the concession or donation 
received from third parties is not recognized in the consolidated balance sheet, since such 
donations are controlled by the concession grantor. 

The amount received to construct infrastructures is recognized in the profit and loss as “Other 
operating income (expenses), net”. 

(a)         Concession arrangements 

The Company operates concession contracts covering the provision of basic and environmental 
sanitation services, water supply and sewage services agreed with the concession grantor. The 
infrastructure used by SABESP subject to service concession arrangements is considered to be 
controlled by the concession grantor when: 

(i) 

(ii) 

The grantor controls or regulates what services the operator must provide with 
the infrastructure, to whom it most provide them, and at what price; and 

The grantor controls the infrastructure, i.e., retains the right to take back the 
infrastructure at the end of the concession. 

SABESP's rights over infrastructure operated under concession arrangements is accounted for 
as an intangible asset as SABESP has the right to charge for use of the infrastructure assets, and 
users (consumers) have the primary responsibility to pay SABESP for the services. 

The fair value of construction and other work on the infrastructure represents the cost of the 
intangible asset and is recognized as revenue when the infrastructure is built, provided that this 
work is expected to generate future economic benefits. The account policy for revenue 
recognition for construction services is detailed on note 2.7 “Revenue from sales and services”. 

Intangible assets under Concession contracts and Program contracts, when there is no right to 
receive the residual value of the assets at the end of the contract, are amortized on a straight-line 
basis over the period of the contract, or the useful life of the underlying asset, what occurs first. 

The investments not recovered in the services provided, during the contract, will be indemnity 
by the concession grantor, (1) in cash or cash equivalent or (2) extend the contract period. These 
investments are amortized over the useful life of the assets. 

(1)   Financial assets are recognized when the Company has the inconditioning right to 

receive cash or cash equivalent in the end of the contract period, as an indemnity for the 
investments not recovered in the services provided, during the contract period. The 
Company did not recognized any financial assets due to the fact that there is no

expectation that the Company will receive cash (historically the contracts period are 
extended); 

(2)  Continuing the operation, the assets will be maintained in the intangible assets. 

(b)         Software licenses 

Software licensing of computer programs and business management systems acquired are 
capitalized and amortized over the period of the license and the expenses associated with 
maintaining these are recognized as expenses when incurred. 

2.13           Impairment  

Property and equipment, intangibles and other noncurrent assets, with defined useful life, are 
reviewed for impairment whenever events or changes in circumstances indicate that the 
carrying amount may not be recoverable.  

The recoverable amount is the higher of value in use and fair value less cost to sell. An 
impairment loss is recognized for the amount by which the asset's carrying amount exceeds its 
recoverable amount. For assets with undefined useful life, so not subject to amortization, it is 
tested annually, not considering the expectation of loss (impairment). The recoverable amount 
is the higher between the amount in use and the fair value less the cost to sell. Impairment is 
recognized in the profit and loss for the amount where the amount of the asset is higher than the 
recoverable amount. For the purposes of measuring impairment, assets are grouped in the 
lowest level for which there are separately identifiable cash flows (CGU - Cash Generating 
Units). The assets adjusted by impairment are reviewed subsequently to analyze the possible 
reversion of the impairment in the date covered by the financial statements, except for goodwill.  

The CGU’s analyzed by the Company to evaluate the recoverable value of the assets were defined 
according to the business decision-maker. Analyzes are performed by business unit, which 
consist in a group of  municipalities which has cost sharing or are supported by the same 
hydrological basin. 

The methodology applied was the discounted cash flow mainly related to the assets related to 
the concessions, considering a five-year period operating cash flow. From 2017 until the 
maturity date of each contract, the operating cash flow is adjusted, annually, by a 4.5% inflation 
rate and discounted by the weighted average cost of capital (WACC). 

The process to estimate the value in use involves premises, judgments and estimates about the 
future cash flows and represents the best estimates of the Company, approved by the board. 

As of December 31, 2011 the Management evaluated that there is no indication that the amounts 
of property and equipment, intangibles and other noncurrent assets will not be recovered by 
future operations. 

2.14           Accounts payable to suppliers and contractors 

Accounts payable to contractors and suppliers are obligations to pay for goods or services 
purchased from suppliers in the ordinary course of business and are classified as current 
liabilities if the payment is due in the period up to one year. Otherwise, the accounts payable are 
presented as non-current liabilities and are initially measured at fair value which generally 
correspond to the amount billed and subsequently to the amortized cost. 

2.15           Loans and financing

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

Borrowings are initially recognized at fair value, upon receipt of funds, net of transaction costs. 
Subsequently, borrowings are stated at amortized cost, and interest is accrued based on the 
effective interest method, as presented in Note 12. Loans and financing are classified as current 
liabilities unless the Company has an unconditional right to defer settlement of the liability for 
at least 12 months after the balance sheet date. 

Nonconvertible debentures are recognized in a similar manner to borrowings. 

2.16           Borrowing costs 

Borrowing costs related to acquisition, construction or production of an asset which, necessarily, 
takes long time to be ready for use or sell are capitalized as cost of the asset. Other costs of the 
loan are recognized as expenses in the period that it occurs. Borrowing costs are interest and 
other financial charges over the loan, including exchange rate variation, in the terms described 
below.  

The capitalization occurs during the period of the construction, considering the weighted 
average rate of the loans in place in the date of the capitalization. 

The loans and financing acquired in foreign currency, are analyzed as they were acquired in 
local currency, and the capitalization of the interest and/or exchange rate variation is limited by 
the amount which would be capitalized if the loans and financing were acquired in local 
currency. 

2.17           Payroll and related charges 

Salaries include an accrual for vacations and the 13th salary and additional payments negotiated 
in collective labor agreements plus related charges and are recorded on the accruals basis. 

2.18          Profit sharing 

The Company's profit sharing plan for its employees is based on general targets of the Company 
as a whole, and based on the performance of each business units. The Company recognizes a 
provision when has a contract or when there is a prior practice which gave rise to a non formal 
obligation (constructive obligation). The expense for profit sharing is recorded on the accruals 
basis as an operating expense and cost of sales and services. 

2.19           Provisions, legal obligation, escrow deposits and contingent assets 

Provisions for legal claims are recognized when: i) the Company has a present legal or 
constructive obligation as a result of past events; ii) it is probable that an outflow of resources 
will be required to settle the obligation; and iii) the amount can be reliably estimated. Where 
there are a number of similar obligations, the likelihood that an outflow will be required in 
settlement is determined by considering the class of obligations as a whole.  

Provisions are measured at the present value of the expenditures expected to be required to 
settle the obligation using a pre-tax rate that reflects current market assessments of the time 
value of money and the risks specific to the obligation. The increase in the provision due to 
passage of time is recognized as interest expense. 

For financial statement presentation purposes, the provisions are stated net of the related 
escrow deposits based on the legal right to offset. The bases and the nature of the provision for 
civil, tax, labor and environmental risks are described in Note 15.

Amounts in thousands of reais, unless otherwise indicated 

Escrow deposits not linked to related liabilities are recorded in noncurrent assets. The escrow 
deposits are restated according to fiscal authorities. 

Legal obligations occur from tax obligation which objective is to claim the legality. The 
obligations are recognized in the financial statements. 

Contingent assets are not recognized, except when the gain is virtually certain or when there are 
real warrants or final judicial decision favorable to the Company. 

2.20         Environmental costs 

Costs related to ongoing environmental programs are expensed as incurred. Ongoing programs 
are designed to minimize the environmental impact of the operations and to manage the 
environmental risks inherent to the Company's activities.  

2.21           Income taxes and social contribution – current and deferred 

The Company adopted a transitory tax regime (RTT) to calculate income tax and social 
contribution, as enacted by law 11,941/09, considering the account effects by law 6,404/76, 
before the changes considered in law 11,638/07. 

This regime will be in place until a new law be enacted. This regime was optional in 2008 and 
2009 and was obliged from 2010 on. 

The Company opted for this regime in 2008. Consequently, the Company adopted the rules 
established in the RTT to December 31, 2011, 2010 and 2009. 

The tax expense for the period comprises current and deferred tax. 

(a)         Current tax 

The current income tax and social contribution expense are calculated on the basis of the laws 
enacted or substantively enacted at the balance sheet date, pursuant to Brazilian tax regulations. 
Income taxes in Brazil comprise Federal income tax (15%), increased by 10% what exceeded 
R$240, and social contribution (9%). Taxable income differs from net income (profit presented 
in the statement of income), because it excludes income and expenses taxable or deductible in 
other years, and excludes items not permanently taxable or not deductible. Management 
periodically evaluates and measures the positions taken in the income tax return with respect to 
situations in which applicable tax regulations are subject to interpretation. It establishes 
provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. 

(b)         Deferred tax 

Deferred income and social contribution taxes are recognized, using the liability method, on 
temporary differences arising between the tax basis of assets and liabilities and their carrying 
amounts in the consolidated financial statements, according to IAS 12. However, the deferred 
income tax is not accounted for if it arises from initial recognition of an asset or liability in a 
transaction other than a business combination that at the time of the transaction affects neither 
accounting nor taxable profit nor loss. Deferred income and social contribution taxes are 
determined using tax rates (and laws) that have been enacted or substantially enacted by the 
balance sheet date and are expected to apply when the related deferred income tax asset is 
realized or the deferred income tax liability is settled.

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

Deferred income and social contribution taxes assets are recognized only to the extent that it is 
probable that future taxable profit will be available against which the temporary differences can 
be utilized.  

Deferred income and social contribution taxes assets and liabilities are offset when there is a 
legally enforceable right to offset current tax assets against current tax liabilities and when the 
deferred income taxes assets and liabilities relate to income taxes levied by the same taxation 
authority on either the taxable entity or different taxable entities where there is an intention to 
settle the balances on a net basis. 

2.22          Accrued taxes on revenues 

Accrued taxes on revenues are recognized on accrual basis for PASEP (Public Servant Fund) and 
Cofins (Social Security Financing Contribution). These taxes are calculated on differences from 
tax basis of billing to government entities, which are taxable when the invoices are settled. As 
these taxes are non-cumulative, they are presented net of tax credits, as deductions from gross 
revenues. Debts and credits arising from other operating income and expenses, respectively, are 
presented as deductions from the respective operating income or expense. 

2.23          Pension obligations 

(a)         Defined benefit 

Liabilities from defined benefit pension plan obligations correspond to the present value of the 
defined benefit obligation at balance sheet date, less the fair value of the plan's assets, and 
adjusted by unrecognized actuarial gains or losses. The defined benefit obligation is calculated 
on an annual basis by independent actuaries, using the projected unit credit method. The 
estimated future cash outflows is discounted to its present value, using the interest rates of 
Government bonds with maturities that approximate the maturity of the related liability. 

The Company adopted the corridor approach to recognize the actuarial gains and losses. 
Actuarial gains and losses arising from experience adjustments and changes in actuarial 
assumptions are in excess of the greater of 10% of the fair value of plan assets or 10% of the 
present value of the defined benefit obligation are charged or credited to income over the 
employees' expected average remaining working lives. The expenses related to pension plan are 
recognized in profit and loss of the year as cost of sales and services, selling expenses or 
administrative expenses, according to employee’s allocation. 

In a event where a curtailment relates to only some of the employees covered by a plan, or where 
only part of an obligation is settled, the gain or loss includes a proportionate share of the 
previously unrecognized past service cost and actuarial gains and losses. The proportionate 
share is determined on the basis of the present value of the obligations before and after the 
curtailment or settlement.  

The Company pays contributions to an unlisted private pension entity, Fundação Sabesp de 
Seguridade Social – Sabesprev, in a compulsory basis, contracted or not. The regular 
contributions consist of the net costs of the plan and are recognized in the profit and loss of the 
period. 

(b)         Defined contribution 

The Company participates in a defined contribution plan (Sabesprev Mais), controlled by a 
closed private pension entity – Fundação SABESP de Seguridade Social (Sabesprev) that 
provide postretirement benefits to the Company´s employees.

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

A defined contribution plan is a pension plan under which the Company makes fixed 
contribution to a closed private pension entity. The Company has no further legal or contractual 
obligation to provide further contributions in case the pension fund is not sufficient to pay the 
benefits to all employees related to the service cost of current or prior period. 

With respect to the defined contribution plan, the Company contributes to Sabesprev on 
mandatory, contractual or voluntary basis. The regular contributions are recognized in the 
income statement of the period. 

2.24          Financial income and expenses 

Financial income is primarily comprised of interest, inflation adjustments and exchange 
variations on short term investments and client negotiation. Financial expenses are primarily 
comprised of interest, inflation adjustments and exchange variations on loans and financing and 
provisions. These financial income and expenses are calculated using the effective interest rate 
method.  

2.25          Leases  

According to IAS 17, leases are classified as financial leases when there is transfer substantially 
all the risks and rewards incidental to ownership of an asset. Other leases are classified as 
operational lease. Operational leases are recognized as expenses in the profit and loss on a linear 
basis during the contract. 

Financial leases are recognized based at lower of the present value of the minimum payment of 
the contract or the fair value of the related asset in the beginning of the contract. The payments 
are recognized as expenses or reducing the leasing in order to obtain a linear interest rate. The 
corresponding obligation is recognized as short or long term debt.  

2.26          Other current and noncurrent assets and liabilities  

Other assets are stated at cost of acquisition, net of any impairment loss, when applicable. The 
amounts recognized as other liabilities are stated at known or estimated amounts, including, 
where applicable, related charges and monetary variations. 

2.27          Dividends and Interest on Shareholders' Equity 

The Company uses the tax benefits of distributing dividends as interest on shareholders' equity, 
as permitted by Brazilian Law. This distribution of dividend is accounted for in accordance with 
Brazilian Law 9,249/95 for tax deductibility purposes, limited to the daily pro rata fluctuation of 
the Long-term Interest Rate (TJLP). The benefit attributed to the shareholders is recognized in 
the current liability against Equity, based on the articles of association. Dividends and interest 
on shareholders´ equity over the minimum established in the articles of association are 
recognized when approved by the shareholders in the general meeting. The tax effects of the 
interest on shareholders’ equity are recognized in the income statement of the year. 

2.28         Present value adjustment 

Current and noncurrent financial assets and liabilities are adjusted to present value based on 
discount rate at current market rate as of the transaction date, when the effects are relevant. 

2.29          New and amended standards adopted by the Company 

                In 2009, the Company has early adopted IAS 24 - Related Party Disclosures (as amended in 

November 2009). The disclosure requirements for entities that are controlled, jointly-controlled

or significantly influenced by a government (referred to as government-related entities) are 
simplified and so detailed disclosures of all transactions with entities controlled by the São 
Paulo State Government are not presented in these financial statements. 

2.30         Standards, amendments and interpretations to existing standards that are not yet 

effective 

Standards, amendments and interpretations to existing standards that are not yet 
effective and have not been early adopted by the Company 

The following new standards, amendments and interpretations to existing standards were 
issued by IASB but are not effective for 2011. The early adoption of these standards, even though 
encouraged by IASB, has not been implemented in Brazil by the Brazilian Accounting 
Pronouncements Committee (CPC). 

.    IAS 19, "Employee benefits" was amended in June 2011. The impact on the Group will be as 
follows: (i) to eliminate the corridor approach; (ii) to recognize all actuarial gains and losses 
in other comprehensive income as they occur; (iii) to immediately recognize all past service 
costs; and (iv) to replace interest cost and expected return on plan assets with a net interest 
amount that is calculated by applying the discount rate to the net defined benefit liability 
(asset). Management is evaluating the total impact of these changes for the Company. The 
standard is applicable as from January 1, 2013.  

.    IFRS 9, "Financial instruments" addresses the classification, measurement and recognition 

of financial assets and financial liabilities. IFRS 9 was issued in November 2009 and October 
2010. It replaces the parts of IAS 39 that relate to the classification and measurement of 
financial instruments. IFRS 9 requires financial assets to be classified into two measurement 
categories: those measured at fair value and those measured at amortized cost. The 
determination is made at initial recognition. The basis of classification depends on the 
entity’s business model and the contractual cash flow characteristics of the financial 
instruments. For financial liabilities, the standard retains most of the IAS 39 requirements. 
The main change is that, in cases where the fair value option is taken for financial liabilities, 
the part of a fair value change due to an entity’s own credit risk is recorded in other 
comprehensive income rather than the statement of income, unless this creates an 
accounting mismatch. Management is evaluating the impact of this standard for the 
Company. The standard is applicable as from January 1, 2013.  

.    IFRS 10, "Consolidated financial statements" builds on existing principles by identifying the 
concept of control as the determining factor in whether an entity should be included within 
the consolidated financial statements of the parent company. The standard provides 
additional guidance to assist in the determination of control. Management is evaluating the 
impact of this standard for the Company. The standard is applicable as from January 1, 2013.  

.    IFRS 11,"Joint arrangements" was issued in May 2011. The standard provides for a more 
realistic reflection of joint arrangements by focusing on the rights and obligations of the 
arrangement, rather than its legal form. There are two types of joint arrangements: (i) joint 
operations - arise where a joint operator has rights to the assets and obligations relating to 
the arrangement and hence accounts for its interest in assets, liabilities, revenue and 
expenses; and (ii) joint ventures - arise where the joint operator has rights to the net assets of 
the arrangement and hence equity accounts for its interest. The proportional consolidation 
method will no longer be permitted in joint ventures. Management is evaluating the impact 
of this standard for the Company. The standard is applicable as from January 1, 2013. 

.    IFRS 12, "Disclosures of interests in other entities" includes the disclosure requirements for 
all forms of interests in other entities, including joint arrangements, associates, special

purpose vehicles and other off balance sheet vehicles. Management is evaluating the impact 
of this standard for the Company. The standard is applicable as from January 1, 2013.  

.    IFRS 13, “Fair value measurement” was issued in May 2011. IFRS 13 aims to improve 

consistency and reduce complexity by providing a precise definition of fair value and a single 
source of fair value measurement and disclosure requirements for use across IFRSs. The 
requirements, which are largely aligned between IFRSs and US GAAP, do not extend the use 
of fair value accounting but provide guidance on how it should be applied where its use is 
already required or permitted by other standards within IFRSs or US GAAP. The Company is 
yet to assess IFRS 13’s full impact. The standard is applicable as from January 1, 2013.  

There are no other IFRSs or IFRIC interpretations that are not yet effective that would be 
expected to have a material impact on the Company. 

3                    Financial Risk Management 

3.1               Financial risk factors 

The Company's activities expose it to a variety of financial risks: market risk (including foreign 
currency risk and interest rate risk), credit risk and liquidity risk. The Company analyzes the 
global risk considering the unpredictability of the financial market and tries to minimize the 
potential adverse financial impacts.  

The Company has not utilized derivative instruments, although it may enter in forward 
exchange transactions and financing funding transactions in Brazilian reais  to mitigate the 
foreign currency exposure.  

(a)         Market risk 

Foreign currency risk 

The Company is exposed to exchange rate fluctuations from Brazilian reais to US dollars and 
Yens. Liabilities in foreign currency include loans in US dollars and Yens. 

Depreciation of Brazilian reais comparing to loans in foreign currency will incur in losses related 
to such liability. 

Foreign currency risks to SABESP are related to the exposure of short and long term loans in 
foreign currency. 

SABESP’s foreign currency risk are monitored considering several actual and projected 
economic factors, beside the market condition. The Company does not have hedge or swap 
contracts to hedge against this risk. The Company monitors the financial debts to reduce the 
exposure to exchange rate variation taking advantage of opportunities to exchange expensive 
debts to cheaper debts by reducing financing costs through early payment of its debts. The 
priority is to acquire new debts with multilateral banks and official agencies from foreign 
governments, which are characterized by low cost and long term maturity.  

On December 31, 2011 and 2010, R$ 3,053.4 million and R$2,248.9 million, which correspond 
to 36.4% and 27.2%, respectively, of the debt of SABESP was denominated in foreign currency. 
The debts of SABESP denominated in foreign currency were acquired, mainly, with Inter-
American Development Bank (IADB). Considering those facts, the Company is exposed to 
foreign exchange fluctuations which can result in material adverse effects to the business. 

The Company's exposure to currency risks are summarized as follows:

As of December 31, 2011, if the Brazilian real had weakened or strengthened by 10% against the 
US dollar and Yen with all other variables held constant, post-tax profit for the year and in the 
shareholders’ equity would have been R$ 201,129 (2010 - R$ 148,146) lower or higher, mainly 
as a result of foreign exchange losses or gains on the translation of foreign currency 
denominated loans.

This risk arises from the possibility that the Company could incur losses due to fluctuations in 
interest rates, increasing the financial expenses related to loans and financing. 

On December 31, 2011 and 2010, R$ 2,537.1 million or 29.5% and R$2.529,4 million or 30.6%, 
respectively, of the debt of SABESP were denominated in Brazilian reais and indexed to UPR 
(“Unidade Padrão de Referência”, a Reference Standard Unit, which is equal to the TR “Taxa 
Referencial”, a Reference Rate). On December 31, 2011 and 2010, R$1,882.3 million or 21.9% 
and R$2,064.7 million or 25.0%, respectively, of the debt of SABESP were denominated in 
Brazilian reais and indexed to the fluctuation of DI (Interbank Deposit) rate. 

On December 31, 2011 and 2010, R$ 1,152.1 million and R$996.1 million, respectively, of the 
debt of SABESP were denominated in US dollars and indexed to the fluctuation of rates of Inter-
American Development Bank (IADB). 

On December 31, 2011 and 2010, the Company has not entered into any derivative contracts to 
hedge againstthe UPR (Reference Standard Unit), DI (Interbank Deposit) or for IADB (Inter-
American Development Bank) rates; however, it continually monitors market interest rates, in 
order to evaluate the possible need to replace its debt. The Company is obliged to invest the 
excess of cash in financial institutions controlled by the Federal Government. 

The Company invest the excess of cash, which corresponded to R$ 2,031.1 million and 
R$1,853.2 million, on December 31, 2011 and 2010, respectively, mainly in short term 
investments. As a result, the exposure of SABESP to interest rate risk is partially limited to the

financial gain of such investments, which normally are indexed to the fluctuation of DI 
(Interbank Deposit) rate. 

The Company maintained approximately 28% of its loans and financing in local and foreign 
currency indexed to fixes rates. During 2011 and 2010, the loans and financing indexed to 
variable rates were in local and foreign currency.

(iv) TJLP (Taxa de Juros a Longo Prazo),a long-term interest rate index. 
(v) IPCA (Índice Nacional de Preços ao Consumidor Amplo), a consumer price index. 

Another risk to which the Company is exposed, is the mismatch of the monetary restatement 
indices of its loans and financing with those of its receivables. Water supply and sewage services 
tariffs do not necessarily follow the increases in the interest rates affecting the Company's 
indebtedness. 

As of December 31, 2011, if interest rates on loans and financing denominated in Brazilian reais  
had been 100 basis points higher or lower with all other variables held constant, post-tax profit 
would have been R$ 35,114 (2010 - R$ 39,338) lower or higher, mainly as a result of a lower or 
higher interest expense on floating rate loans and financing. 

(b)         Credit risk 

Credit risk arises from cash and cash equivalents, deposits in banks and financial institutions, as 
well as credit exposures to wholesale and retail customers, including outstanding accounts 
receivable. The Company is required by law to invest its surplus cash with financial institutions 
controlled by the State Government. Credit risk exposure to retail customers is mitigated by 
sales to a geographically dispersed customer base.  The maximum exposure to credit risk at the 
reporting date are the amounts of  cash equivalents, deposits in banks and financial institutions, 
wholesale and retail customers  in the balance sheet. (See notes 5, 6 and 7). 

The credit quality of financial assets that are neither past due nor impaired can be assessed by 
reference to external credit ratings (if available) or to historical information about counterparty 
default rates. The credit quality of counterparties which are banks, such as cash and cash 
equivalents, the Company considers the lower rating of the counterparty published by three 
mainly international agency of rating (Moody's, Fitch e S&P), according to internal policy of 
management of market risk:

(c)         Liquidity risk 

The Company's liquidity is primarily reliant upon cash provided by operating activities, 
borrowings from Brazilian Federal and State governmental financial institutions, and financing 
in the domestic and international capital markets. The liquidity risk management considers the 
assessment of its liquidity requirements to ensure it has sufficient cash to meet operational and 
capital expenditures needs.  

The excess of cash is invested in short-term investment indexed by interest, deposits held at call 
with banks, other short-term highly liquid investments considering appropriate maturity date 
and liquidity.

liabilities into relevant maturities based on the balance sheet as of December 31, 2011 and 2010.

3.2              Capital management 

The Company's objectives when managing capital are ensure its ability to continue as a going 
concern in order to provide returns for shareholders and benefits for other stakeholders, and to 
maintain an optimal capital structure to reduce the cost of capital. 

The Company monitors capital based on the leverage ratio. This ratio corresponds to net debt 
divided by total capital. Net debt corresponds to total loans and financing (including short and 
long term loan and financing, as presented in the financial statements) less cash and cash 
equivalents. Total capital is calculated as total equity as shown in the balance sheet plus net 
debt. 

The financial leverage rate on December 31, 2011 and 2010 as summarized below:

In 2010, the Company's leverage ratio decreased to 37.9% as of December 31, 2011, compared to 
39.3% as of December 31, 2010, due to increase in short term investments. 

The capital is not managed at consolidated level, but only at parent company level, whereas the 
subsidiaries are not relevant. 

3.3              Fair value estimates 

The Company adopted the amendment to IFRS 7 for financial instruments that are measured in 
balance sheet at fair value, which requires the disclosure of fair value measurements by level of 
the following fair value measurement hierarchy: 

.     Quoted prices (unadjusted) in active markets for identical assets and liabilities (level 1). 

.     Inputs other than quoted prices included within level 1 that are observable for the asset or 

liability, either directly (that is, as prices) or indirectly (that is, derived from prices) (level 2). 

.     Inputs for the asset or liability that are not based on observable market data (that is, 

unobservable inputs) (level 3). 

The fair value of financial instruments traded in active markets is based on quoted market prices 
at the balance sheet date. A market is regarded as active if quoted prices are readily and 
regularly available from an exchange, dealer, broker, industry group, pricing or service, or

regulatory agency, and those prices represent actual and regularly occurring market 
transactions on an arm's length basis. The quoted market price used for financial assets is the 
current bid price. These instruments are included in level 1. 

The fair value of financial instruments that are not traded in an active market (for example, time 
deposits  and  certificates  of  bank  deposit)  is  determined  by  using  valuation  techniques.  These 
valuation techniques maximize the use of observable market data where it is available and rely 
as little as possible on entity specific estimates. If all significant inputs required to fair value an 
instrument are observable, the instrument is included in level 2. 

If one or more of the significant inputs is not based on observable market data, the instrument is 
included in level 3. 

Specific valuation techniques used to value financial instruments include: 

.     Quoted market prices or dealer quotes for similar instruments. 

.     Other techniques, such as analysis of discounted cash flows, are used to determine the fair 

value of the remaining financial instruments. 

The only financial instrument measured at fair value are represented by the short-term 
investment on Certified of Bank Deposits (CDB), classified as cash equivalent, amounting to R$ 
2,031,122 and R$ 1,853,177 in December 31, 2011 and 2010, respectively. These investments are 
measured at fair value through profit and loss at level 2. 

3.4              Financial Instruments 

The Company operates with many financial instruments, particularly cash and cash equivalents, 
including financial investments, and loans and financing as described below.

4                    Critical accounting estimates and judgments 

Estimates and judgments are continually evaluated and are based on historical experience and 
on other factors, including expectations of future events that are believed to be reasonable under 
the circumstances.  

The Company makes estimates and assumptions concerning the future. The resulting 
accounting estimates will, by definition, seldom equal the related actual results. The estimates 
and assumptions that have a significant risk of causing material adjustment to the carrying 
amounts of assets and liabilities within the next financial year are addressed below: 

(a)          Allowance for doubtful accounts 

The Company records allowance for doubtful accounts in an amount that management 
considers sufficient to cover probable losses, based on an analysis of customer accounts 
receivable, in accordance with the accounting policy stated in Note 2.8. 

The 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 the Company believes that the estimates used are reasonable, 
actual results could differ from those estimates.  

(b)          Intangible assets arising from concession contracts 

The Company recognizes intangible assets arising from concession contracts under IFRIC 12. 
The Company estimates the fair value of construction and other work on the infrastructure to 
recognize the cost of the intangible asset, which is recognized when the infrastructure is built 
and provided that it will generate future economic benefits. The great majority of the Company's 
contracts for service concession arrangements entered with each grantor is under service 
concession agreements in which the Company has the right to receive, at the end of the contract, 
a payment equivalent to the unamortized asset balance of the concession intangible asset, which 
in this case, are amortized over the useful life of the underlying physical assets, thus at the end 
of the contract, the remaining value of the intangible would be equal to the residual value of the 
related physical asset.  

Concession intangible assets under Concession contracts and Program contracts, in which, at 
the end of the contract, the Company has no right to receive a payment equivalent to the 
unamortized asset balance of the concession intangible, are amortized on a straight-line basis 
over the useful life of the asset or the contract, what incur first. Additional information on the 
accounting for intangible assets arising from concession contracts is disclosed in Note 2.12(a). 

The recognition of fair value for the intangible assets arising on concession contracts is subject 
to assumptions and estimates, and the use of different assumptions could affect the balances 
recorded. The estimated useful lives of the underlying assets also requires significant 
assumptions and estimates, which different assumptions and estimates and changes in future 
circumstances, could affect the remaining useful lives of the intangible assets and can have a 
significant impact on the results of operations. 

(c)          Impairment of long-lived assets 

The Company reviews annually long-lived assets for indicators of impairment, primarily 
intangible assets arising from concession contracts, which include water and sewage system

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

physical assets to be held and used in the business, for the purpose of determining and 
measuring impairment when events or changes in circumstances indicate that the carrying value 
of an asset or group of assets may not be recoverable. The assets include the intangible asset of 
the concession contracts related to water and sewage systems. 

In evaluating impairment of long-lived assets, the evaluation requires 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 and/or the period of the contract, among other factors. 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 the Company believes that the estimates used are 
reasonable, the use of different assumptions could materially affect the recoverable amount. 

(d)          Provisions 

The Company is party to a number of legal proceedings involving significant claims. These legal 
proceedings include, among other types, tax, labor, civil, environmental, dispute with customers 
and suppliers and other proceedings. Additional information of these legal proceedings is 
disclosed in Note 15. The Company accrues for probable losses resulting from these claims and 
proceedings when the Company determines that the likelihood that a loss has occurred is 
probable and the amount of such loss can be reasonably estimated. Therefore, the Company is 
required to make judgments regarding future events. As a result of the significant judgment 
required in assessing and estimating these provisions for contingencies, actual losses realized in 
future periods could differ significantly from actual estimates and could exceed the amounts 
provisioned.  

Provisions are measured at the present value of the expenditures expected to be required to 
settle the obligation using a pre-tax rate that reflects current market assessments of the time 
value of money and the risks specific to the obligation. The increase in the provision due to 
passage of time is recognized as interest expense. 

(e)          Pension benefits 

The present value of the pension obligations depends on a number of factors that are 
determined on an actuarial basis using a number of assumptions, which can differ materially 
from the real, due to the changes in economic and market conditions. The assumptions used in 
determining the net cost (income) for pensions include the discount rate. Any changes in these 
assumptions will impact the carrying amount of pension obligations. 

The Company determines the appropriate discount rates at the end of each year, which is the 
interest rate that should be used to determine the present value of estimated future cash 
outflows expected to be required to settle the pension obligations. The Company utilizes the 
interest rate of high quality private papers to determine the appropriate discount rate, which are 
in the same currency of the payments of the benefits and which has the maturity date close to 
the respective obligation. 

Other key assumptions for pension obligations are based in part on current market conditions. 
Additional information on the pension plans under Plan G0 and G1 is disclosed in Note 16.

Cash and cash equivalents are denominated in Reais. Cash equivalents are mainly represented 
by Bank Deposit Certificates - CDB's, deposited in financial institutions controlled by the São 
Paulo State Government, which has maturity date less than three months and are ready to be 
converted in cash and has an insignificant risk to change the total amount. 

In December 2011, the average rate of such Cash equivalents was 100.19% of CDI (Interbank 
Deposit Certificates). In December 2010, the average rate was 99.2% of CDI.

In December 31, 2011, the restricted cash totaled R$ 99,729 (R$ 302,570 in 2010) and was 
recognized in the current asset. Approximately R$8,280 was related to BNDES guarantees and 
R$ 90,984 referred to proceeds from services provided to entities related to the Municipal 
Government of São Paulo, net of taxes, which include: day-care centres, schools, management

Amounts in thousands of reais, unless otherwise indicated 

(i)     Water and sewage services 

The Company provides water supply and sewage collection services to the São Paulo State 
Government and other companies related to it in accordance, considered by management,  
as usual market terms and conditions, except for the settlement of receivables which may 
occur as mentioned in items (iii), (iv) and (v). 

(ii)   Reimbursement for pension benefits paid  

Refers to amounts of supplementary retirement and pension benefits provided for in State 
Law 4,819/58 ("Benefits") paid by the Company to former employees and pensioners. 

Under the Agreement with the São Paulo State Government ("GESP" or the "State"), dated 
December 11, 2001, GESP recognizes its liability from charges arising from the Benefits, 
provided that the payment criteria set forth by the State Department of Personnel (DDPE), 
based on legal guidance of the Legal Consultancy of the Department of Finance and of the 
State Attorney General's Office (PGE). 

As discussed on item (vii), during the assessment of the debt due from GESP to the 
Company there were certain divergences in the calculation and eligibility criteria of the 
benefits paid by the Company on behalf of GESP. 

For the years ended December 31, 2011, 2010 and 2009, 2,492, 2,554 and 2,597 retired 
employees, respectively, received additional retirement benefits, and for the years ended 
December 31, 2011, 2010 and 2009, the Company paid R$ 124,421, R$ 118,408 and 
R$ 116,082 respectively. There were 14 active employees as of December 31, 2011 who will 
be entitled to these benefits as a result to their retirement as compared to 32 as of 
December 31, 2010 and 91 as of December 31, 2009. 

In January 2004, the payments of supplement retirement and pension benefits were 
transferred to the Department of Finance and would be made in accordance with the 
calculation criteria determined by the PGE. As a result of a court decision, the 
responsibility for making the payments returned to SABESP, as originally established. 

(iii) GESP Agreement 

On December 11, 2001, the Company, the São Paulo State Government (through the State 
Department of Finance Affairs, currently Department of Finance) and the Water and 
Electricity Department (DAEE), with the intermediation of the State Department of 
Sanitation and Energy (former Department of Water Resources, Sanitation and 
Construction Works), entered into the Obligations, Payment Commitment and Other 
Covenants Acknowledgement and Consolidation Agreement ("GESP Agreement") for the 
settlement of outstanding debts between GESP and the Company related to the provision of 
water supply and sewage services and to the Benefits. 

In view of the strategic importance of the Taiaçupeba, Jundiaí, Biritiba, Paraitinga and 
Ponte Nova reservoirs for ensuring and maintaining the Upper Tietê water volume, the 
Company agreed to receive them as partial repayment of the reimbursement related to the 
Benefits. The DAEE would transfer the reservoirs to the Company, replacing the amount 
owed by GESP. However, the São Paulo State Public Prosecution Office challenged the legal 
validity of this agreement, and its main argument is the absence of a specific legislative 
authorization for disposal of DAEE's assets. The Company's legal advisors assess the risk of 
loss in this lawsuit as probable, in case the legislative authorization is not obtained, which 
would hinder the transfer of the related reservoirs as a partial settlement of the balance 
receivable.

(iv) First Amendment to the GESP Agreement 

On March 22, 2004, the Company and the São Paulo State Government amended the terms 
of the original GESP Agreement, (1) consolidating and recognizing the amounts due by the 
São Paulo State Government for water supply and sewage collection services provided, 
monetarily adjusted through February 2004; (2) formally authorizing the offset of amounts 
due by the São Paulo State Government with interest on shareholders' equity declared by 
the Company and any other debt owed to the São Paulo State Government as of December 
31, 2003, monetarily adjusted through February 2004; and (3) defining the payment 
conditions of the remaining liabilities of the São Paulo State Government for the receipt of 
the water supply and sewage services. 

(v)    Second Amendment to the GESP Agreement 

On December 28, 2007, the Company and the São Paulo State Government, represented by 
the Department of Finance, signed the second amendment to the terms of the original 
GESP Agreement, agreeing upon the payment in installments of the remaining balance of 
the First Amendment, amounting to R$ 133,709 at November 30, 2007, to be paid in 60 
monthly and consecutive installments of the same amount, beginning on January 2, 2008. 
The amount of the installments will be monetarily restated according to the fluctuation of 
the IPCA-IBGE, plus interest of 0.5% per month.  

The State and SABESP agreed on immediately resuming their compliance with their mutual 
obligations under new assumptions: (a) implementation of an electronic bill management 
system to facilitate and speed up the monitoring of payment processes and budget 
management procedures; (b) structuring of the Rational Water Use Program (PURA) to 
rationalize the consumption of water and the amount of the water and sewage bills under 
the responsibility of the State;  (c) establishment, by the State, of criteria for budgeting so 
as to avoid the reallocation of amounts to a specific water and sewage accounts as from 
2008; (d) possibility of registering state bodies and entities in a delinquency system or 
reference file; (e) possibility of interrupting water supply to state bodies and entities in the 
case of nonpayment of water and sewage bills. 

 (vi) Third Amendment to the GESP Agreement 

On November 17, 2008, GESP, SABESP and DAEE signed the third amendment to the 
GESP Agreement, through which GESP recognized a debt balance payable to SABESP 
totaling R$ 915,251, monetarily adjusted up to September 2008 in accordance with the 
fluctuation of the IPCA-IBGE, corresponding to the Undisputed Reimbursement (see item 
(iii) above), determined by FIPECAFI. SABESP accepted on a provisional basis the 
reservoirs as part of the payment of the Undisputed Reimbursement and offered to GESP a 
provisional settlement, recognizing a credit totaling R$ 696,283, corresponding to the 
value of the reservoirs in the Upper Tietê system. The Company did not recognize the 
reimbursement receivable of R$696,283 related to the reservoirs, as it is not virtually 
certain that will be transferred by the State. The final settlement will only be effected with 
the actual transfer of the property with the proper Registry of Deeds Office. The remaining 
balance totaling R$ 218,967 is being paid in 114 monthly, consecutive installments,  
totaling R$ 1,920 each, including the annual IPCA/FIPE fluctuation, plus interest of 0.5% 
p.m., the first of which fell due on November 25, 2008.  

The Company and the São Paulo State Government are working together to obtain 
legislative authorization to transfer the reservoirs to SABESP, overcoming the uncertainties 
arising from the public lawsuit challenging the absence of a specific legislative 
authorization for the transfer of the property of the reservoirs.

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

In addition, the third amendment provides for the regularization of the monthly flow of 
benefits. While SABESP is liable for the flow of monthly payment of benefits, the State shall 
reimburse SABESP based on the criteria identical to those applied when determining the 
Undisputed Reimbursement. Should there be no preventive court decision, the State will 
assume the flow of monthly payment of benefits portion deemed as undisputed. 

(vii) Controversial Amount of Benefits 

As mentioned before, on November 17, 2008 the Company and the State signed the third 
amendment to the GESP Agreement, when the reimbursements called disputed and 
undisputed were quantified. The amendment established the efforts to calculate the so-
called Disputed Reimbursement of the Benefits. Under the fourth clause of the amendment, 
the Disputed Reimbursement represents the difference between the Undisputable 
Reimbursement and the amount actually paid by the Company as pension benefits and 
pensioners set out in Law 4,819/58, for which, the Company understands, the State of São 
Paulo is originally liable, but paid by SABESP by May 2008, under a court order. 

By entering into the third amendment, the State's Legal Representative (PGE) agreed to 
reassess the differences that gave rise to the disposed reimbursement of benefits set out in 
Law 4,819/58. At the time, the expectation was based on the willingness of the PGE to 
reanalyze the issue and the implied right of the Company to the reimbursement, including 
based on opinions from outside legal advisors. 

However, new opinions issued by the PGE and received on September 4 and 22, 2009 and 
January 4, 2010, refute the reimbursement of the largest portion of the controversial 
amount.  

Even though the negotiations with the State are still in progress, it is not possible to assure 
that the Company will recover the receivables related to the Disputed Reimbursement 
without dispute. 

As part of the actions intended to recover the receivables that management considers due 
by the State, related to discrepancies in the reimbursement of the pension benefits paid by 
the Company, the Company: (i) on March 24, 2010, reported to the controlling shareholder 
the official letter approved by the executive committee, proposing that the matter be 
discussed at the São Paulo Stock Exchange (BM&FBovespa) Arbitration Chamber; (ii) in 
June 2010, presented to Department of Finance a proposal to solve the outstanding items, 
such proposal was not accepted; (iii) on November 9, 2010, filed a judicial action against 
the State of São Paulo pleading the entire reimbursement related to employee benefits set 
out in Law 4,819/58 to finalize the discussion between the Company and GESP. The 
Company will persist to obtain an agreement with GESP since the management believes 
that it is the better to the Company and to its shareholders than wait until the end of the 
judicial action.  

The Company's management decided to not recognize the reimbursements which were not 
considered virtually certain that will be reimbursed by the State. As of December 31, 2011 
and 2010, the amounts not recorded by the Company, related to the pension benefits paid 
on behalf of the State by the Company, totaled R$ 1,290,663 and R$ 1,230,064, 
respectively, including the amount of R$ 696,283 related to the transfer of the reservoirs in 
the Upper Tietê system. As a result, the Company also recognized the obligation related to 
the pension benefit obligations maintained with the beneficiaries and pensioners of Plan 
G0, whose right it is to be paid by SABESP and is not considered virtually certain that 
SABESP will be reimbursed by the State. As of December 31, 2011 and 2010, the pension 
benefit obligations of Plan G0 totaled R$ 1,512,078 and R$ 1,316,706, respectively. For 
detailed information on the pension benefit obligations refer to Note 16.

(b)          Agreements for the use of reservoirs 

In its operations, the Company uses the Guarapiranga and Billings reservoirs, which are owned 
by another entity controlled by the São Paulo State Government; should these reservoirs not be 
available for use to the Company, there could be the need to collect water in more distant places. 
The Company does not pay any fee for the use of these reservoirs but it is responsible for their 
maintenance and operating costs. 

(c)          Agreements with reduced tariffs with State and Municipal Government Entities that joined the 

Rational Water Use Program (PURA).  

The Company has signed agreements with government entities related to the State Government 
and municipalities where it operates that benefit from a reduction of 25% in the tariff of water 
supply and sewage services when they are not in default. These agreements provide for the 
implementation of the rational water use program, which takes into consideration the reduction 
in the consumption of water. 

 (d)         Guarantees 

The State Government provides guarantees for some loans and financing of the Company and 
does not charge any fee with respect to such guarantees.  

(e)          Personnel assignment agreement among entities related to the State Government 

The Company has personnel assignment agreements with entities related to the State 
Government, under which the expenses are fully passed on and monetarily reimbursed. In 2011, 
the expenses related to personnel assigned by SABESP to other state government entities 
amounted to R$ 10,888 (2010 - R$ 5,640 and 2009 - R$ 5,359). 

In 2011 there was no personnel assigned by other entities to SABESP. In 2010, the expenses 
related to personnel assigned by other entities to SABESP totaled R$264 and in 2009 totaled R$ 
335.  

(f)           Services obtained from entities related to the State Government 

As of December 31, 2011 and 2010, SABESP had an outstanding amount payable of R$ 12,062 
and R$ 11,395, respectively, for services rendered by São Paulo State Government entities, 
including the supply of electric power by Companhia Energética de São Paulo – CESP, which 
represents 86% in 2011.  

(g)          Nonoperating assets 

As of December 31, 2011 the Company had an amount of R$ 21,531 (December 31, 2010 - R$ 
25,371) mainly related to free land lend to the associations, support entities, non-governmental 
organizations and to DAEE (Water and Electricity Department), among others. The free land 
lend to DAEE amounts to R$ 2,289. 

(h)          Banco do Brasil 

The State of Sao Paulo sold exclusive rights in the provision of banking services administration 
entities directly and indirectly in favor of Banco Nossa Caixa, on March 27, 2007, and in favor of 
Banco do Brasil, May 27, 2010. Through the lawsuit in question, SABESP pleads financial 
compensation for the sale of its exclusive rights, requiring a percentage of the values that the 
State of São Paulo received from each of the financial institutions.

On June 28, 2011 it was executed the Term of Settlement between the Company and the State of 
Sao Paulo, whereby the Company received the amount of R$ 63,366 upon reduction, as 
compensation of credit held by the State, corresponding to interests on shareholders’ equity in 
fiscal 2010. 

(i)           SABESPREV 

The Company sponsors a private defined benefit pension plan, which is operated and 
administered by Fundação SABESP de Seguridade Social - SABESPREV. The net actuarial

Directors' compensation is equivalent to 30 percent of the executive committee' overall

form of interest on shareholders' equity. Annual bonuses cannot exceed the lower of six times 
the monthly compensation of the officers/directors nor 10 percent of the interest on 
shareholders' equity paid by the company.  

Annual award:  

Equivalent to a monthly fee, calculated on a prorated basis in December of each year. 

The purpose of this award is to correspond to the thirteenth salary paid to Company employees, 
as officers and directors' relationship with the Company is governed by its bylaws and not the 
labor code. 

Benefits: paid only to officers - meal ticket, basket of food staples, medical care, weekly paid rest 
typified as a paid leave of 30 calendar days, and payment of a premium equivalent to one third

2009 – R$ 856). 

9                    Indemnities Receivable 

Indemnities receivable are a noncurrent asset that represents amounts receivable from the 
Municipality of Diadema as an indemnity for their unilateral termination of the concession for 
water supply and sewage services of the Company in 1995. As of December 31, 2011, this balance 
totaled R$ 60,295. As of December 31, 2010, the indemnities receivable was R$146,213 related 
to the municipalities of Diadema R$ 60,295 and Mauá R$85,918. 

The Company invested in the construction of water and sewage systems in the municipalities of 
Diadema and Mauá in order to meet the concession service commitments. For the unilateral 
termination of the Diadema and Mauá concessions, the municipalities assumed the 
responsibility of supplying water and sewage services in those regions. At that time, the 
Company reclassified the balances of property, plant and equipment related to the assets used in 
those municipalities to noncurrent assets (indemnities receivable). 

As of December 31, 2011, the net book value of property, plant, and equipment relating to the 
municipality of Diadema, reclassified in December 1996, amounted to R$ 75,231 and the 
indemnity balance from the municipality amounted to R$ 60,295, on December 31, 2011. 

SABESP filed lawsuits to collect the amounts due by the municipalities. With respect to 
Diadema, the decision of the lower court judge was unfavorable to SABESP. The Company filed 
an appeal and in December 2005, SABESP's appeal to have the agreement entered into with the 
municipality of Diadema declared valid was partially accepted. In December 2007, the decision 
that accepted the execution of the Companhia de Saneamento the Diadema - Saned was 
rendered, ordering this company to be summoned to pay the full amount of the debt within 15 
days under the penalty of fine. The judge approved the seizure of cash from Saned's bank 
accounts and short-term investments (online seizure) of up to 10% of the adjusted debt. An 
appeal was filed against this decision, but the Appellate Court upheld the final and unappealable 
decision. R$ 2,919 were seized and withdrawn on March 3, 2009. Subsequently, the Court of 
Justice issued an injunction determining the seizure through weekly deposits by Saned in the 
amount corresponding to 20% of everything received in its bank accounts and short-term 
investments.  

In October 2009, a judicial decision recognized the debt and the execution against the 
municipality which will pay using precatory. In September 2011, the Company received a 
favorable decision from the Court of Justice, considering constitutional the municipal law which 
permitted the retention of the ICMS.   

On December 29, 2008, Saned and the Municipality of Diadema entered into a Letter of Intent 
with the São Paulo State and SABESP for the purpose of preparing studies and conducting 
negotiations to guide Diadema's and SABESP's decisions, aiming to establish SABESP as the 
exclusive provider of water supply and sewage services for the City of Diadema. 

The parties agree that the settlement of the existing conflicts between the companies is 
indispensable for the proper development of the public utility services of water supply and 
sewage services in the municipality of Diadema. 

In January 2009, the parties filed a joint petition requesting the suspension of new seizures, for 
a three-month period, trying to enable an agreement. The suspension was confirmed by the Tax 
Court. As the settlement on which a possible agreement will be based was maintained, the 
suspension request was last renewed in November 2011.

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

As of December 31, 2011, the net book value of property, plant, and equipment relating to the 
municipality of Mauá, reclassified in December 1999, totaled R$ 103,763 and the indemnities 
receivables the municipality totaled R$ 85,918. The decisions are being favorable to the 
Company and the collection will be made by precatory, which will be recognized in the financial 
statements when realized, due to the uncertainties in the collection. Due to this fact, in 
December 2011, the Company recognized a provision for losses in the total amount and the 
judicial demand is still in progress. 

With respect to Mauá, a lower court decision demanded this Municipality pay the amount of 
R$ 153.2 million to SABESP as a compensation for the investments made by SABESP in the city 
and for the loss of profits. In August 2008, the Court of Justice decided for the integral 
maintenance of the lower court decision. The Municipality of Mauá filed special and 
extraordinary appeals against the decision. Both appeals were denied by the Court of Justice, 
which led to the filing of a bill of review with the Superior Court of Justice and Federal Supreme 
Court. The Federal Supreme Court partially accepted the appeal to reduce the fees.  

Based on legal opinion, management believes that the Company has legal rights to receive the 
indemnities and is monitoring the judicial lawsuit.

Intangible rights arising from concession contracts 

The Company operates concession contracts as defined by IFRIC 12 covering the provision of basic 
and environmental sanitation services, water supply and sewage services. These concession 
arrangements set out rights and obligations relative to the infrastructure and to the public service 
(See Note 2.12(a)). A general obligation also exists to return the concession infrastructure to the 
grantor in good working condition at the end of the concession. 

As of December 31, 2011 and 2010, the Company operates in 363 municipalities in the State of São 
Paulo. In most of these municipalities operations are based on 30-year concession period. The 
agreement with the municipality of São Paulo is accounted for as a service concession arrangement. 

The services provided by the Company are billed at a price established by the "Agência Reguladora 
de Saneamento e Energia do Estado de São Paulo" ("ARSESP").Intangible rights arising on 
concession contracts are comprised of: 

(i) Service concession agreements 

The concession contracts state that the property will revert to the grantor at the end of the 
period, through compensation for the residual value or market value of the underlying 
physical assets in accordance with the stipulations in each contract and amortization are 
calculated using the straight-line method, which consider the physical assets economic useful 
lives. 

(ii)          Concession contracts 

From 1999 through 2006, the negotiations for new concessions were conducted on the basis 
of the economic and financial profit or loss of the transaction, determined in a valuation 
report issued by independent appraisers.

2.           The State and the Municipality sets forth ARSESP as the  agency responsible for 

regulating the tariff, controlling and monitoring the services; 

3.           The evaluation model of the  contract was the discounted cash flow which 
considered the financial and economic sustainability of the operation; 

4.           All operational costs, taxes, investments and the opportunity cost of the investees 

and the creditors of SABESP were considered in the cash flow analysis; 

5.           The estimated investments mentioned in the agreement comply with 13% of the 

gross revenue from the municipality of São Paulo, net of the taxes on revenues. 
The investment plan, considering the execution of SABESP, must be compatible 
to the activities and programs included in the sanitation plan of the State, 
Municipality, and if necessary, in the plan of the Metropolitan region. The invest 
plan is not irrevocable and will be reviewed by management committee each four 
years, specially the investments to be executed in the subsequent period; 

6.           The payment related to the Municipal Fund of Environmental Sanitation and 

Infrastructure to be applied in the sanitation service within the municipality must 
be recovered through the tariffs charges. Such payment represents 7.5% of the 
total revenue from the municipality of São Paulo, net of the taxes on revenue; 

7.           The opportunity cost of the investees and the creditors was established by the 

Weighted Average Cost of Capital (WACC) methodology. The WACC was the 
interest rate used to discount the cash flow of the operation; 

8.           The agreement considers the recovery of the assets in operation, evaluated by 

external specialists or by historical costs plus monetary indexation, to be defined 
by ARSESP. There should be no residual amount of the assets at the end of the 
contract. 

The agreement represents approximately 55.1% of the total revenue of the Company. 

The Company and the municipality of São Paulo did not achieve an agreement to solve the 
financial pending accounts in place in the date of the contract signature, related to the water 
and sewage services provided to the property of the municipality. Due to this fact, the 
Company filed a lawsuit to collect the amounts due by the municipality.

60 month-period agreement to provide specialized technical services to implement a

The Company opted to adopt the Transition Tax Regime (RTT), established by Provisional 
Measure 449/08, converted into Law No. 11,941/2009. Accordingly, the effects from the 
changes in Law 11,638/07 and from articles 36 and 37 of the said Provisional Measure had no 
effects for tax purposes. 

Due  to  the  adoption  of  this  regime,  the  Company  maintained  the  tax  incentives  arising  from 
donations and government´s investment subsidy and the tax deductibility for debt issuance cost 
on loans and financing.

Approximately 1,500 lawsuits were filed by commercial customers, which claim that their tariffs 
should be equal to the tariffs of another consumer category, and therefore claim the refund of 
the  amounts  collected  by  SABESP.  The  Company  was  granted  both  favorable  and  unfavorable 
final  decisions  at  several  courts,  and  recognized  a  provision  when  the  likelihood  of  loss  is 
considered  probable.  The  change  of  R$  40.6  million  (net  of  escrow  deposit)  in  the  lawsuits 
classified  as  probable  loss  (see  item  “a”  above)  arose  from  the  change  in  the  likelihood  of 
ongoing lawsuits, interest, fees and adjustments. 

(ii)        Supplier claims 

include  claims 

Suppliers'  claims 
filed  by  some  construction  companies  alleging  an 
underpayment of monetary adjustments, withholding of amounts related to the understatement 
of official inflation rates after the Real economic plan, and the economic and financial imbalance 
of  the  agreements.  These  lawsuits  are  in  progress  at  different  courts  and  a  provision  is 
recognized when the likelihood of loss is

considered probable. In 2011, the increase of R$ 48.7 million and R$ 92.7 million (net of escrow 
deposit) in lawsuits whose likelihood of loss is considered probable and possible, respectively, is 
related to interest, fees and inclusion of monetary restatement of the lawsuits in course. 

(iii)       Other civil claims 

The Company is a party to several civil lawsuits related to indemnities for property damage, pain 
and suffering, and loss of profits allegedly caused to third parties. As of December 31, 2011, total 
accrued  amount  of  R$ 178.4  million  (December  31,  2010  -  R$ 167.7  million)  refers  to  claims 
with a likelihood of loss is considered probable. There was an increase in lawsuits with probable 
and  possible  risk  of  loss,  arising  from  the  increase  in  lawsuits  and  comprising  monetary 
adjustment, interest and fees. 

(iv)        Tax claims 

The provision for tax contingencies refers mainly to issues related to tax collections challenged 
due to differences in the interpretation of legislation by the Company's legal advisors. The 
increase of R$71.5 million in the lawsuit considered as possible loss is mainly related to 
monetary adjustments of the lawsuit claimed by the municipality of São Paulo, as described in 
item (b) below. 

(a)          In 2006, the Federal Revenue Service, by means of a tax execution, audited the Company's 

compliance with the tax obligations related to income tax and social contribution for calendar 
year 2001, and recognized taxes payable in the amount of R$ 379.3 million, adjusted through 
December 31, 2011 (R$ 357.7 million in 2010). The Company filed a timely objection and will 
appeal against the tax assessment at administrative level and in courts. According to legal 
advisors, the likelihood of loss of this administrative proceeding is considered remote to 
approximately 90% and 10% is considered possible. 

(b)          The company filed for a preliminary injunction to challenge the revocation of the tax on service 
revenue exemption granted by the Municipality of São Paulo, under a City Law enacted in 2002. 
In April 2003, the exemption was granted and the tax payment was suspended by an injunction. 
In May 2005, the courts issued a decision overruling the injunction. In July 2005, SABESP filed 
an appeal to ensure the preliminary injunction granted remained in effect. In January 2012, the 
appeal was denied, and due to omission existing in the decision the Company filed an 
amendment of judgment including the requesting for modification of the decision, which is 
awaiting judgment. The assessment note filed by the municipality of São Paulo, requesting the 
tax credit related to ISS (municipal tax) and penalties due to non accomplishment of the duties, 
are in place the injunction conceded in the precautionary action, still awaiting judgment to 
annul the administrative decision.  As of December 31, 2011, the estimated amount of the claim 
is R$ 223.9 million (R$ 178.7 million in 2010). The Company's legal advisors assessed the 
likelihood of loss as possible.  

(c)          The Federal Revenue Service rejected some offset requests made by the Company for the 

extinction of IRPJ/CSLL payable, using favorable amounts, arising from undue payments of 
IRPJ/CSLL, which were paid based on monthly estimates. The amount involved is estimated at 
R$ 44.7 million adjusted through December 31, 2011 (R$ 40.9 million in 2010). The legal 
advisors assessed it has a possible loss. 

(d)          The Company requested an authorization to offset the Corporate Income Tax (IRPJ) and Social 

Contribution on Net Income (CSLL) of the period of July, August and September 2002 against 
the amount of IRPJ paid in excess in 1997 and 1998, due to reallocation of monetary 
adjustments in the financial statements (Law 8,200/91) which were anticipated in 1996 due to a 
injunction, after excluded due to the give up of the process and acceptance of the Provisional 
Measure 38/02, which was rejected. After the judgment by the Administrative Council of tax 
resources, the credit related to 1997 was not accepted. The estimated amount is R$ 41.0 million

Notes to the Consolidated Financial Statements  
Amounts in thousands of reais, unless otherwise indicated 

as of December 31, 2011 (R$ 39.1 million in 2010). The Company´s legal advisors assessed this 
claim as a possible loss. 

(e)          On June 23, 2010, the Company and the municipality of São Paulo signed an agreement to 

provide water supply and sewage services. The negotiation of this agreement led to the 
extinction of some judicial lawsuits.  However, others did not take place in the adjustment and 
are continuing regularly. The remaining judicial lawsuits considered as probable and possible 
loss are mainly related to taxes and fines. As of December 31, 2011 the amounts of such judicial 
lawsuits were R$ 27.7 million and R$ 30.6 million, respectively (R$ 22.3 million and R$27.2 
million, respectively, in 2010). 

(f)           In 2005, the Federal Revenue Service partially rejected the Company´s request of offsetting tax 
credits related to the Corporate Income Tax (IRPJ) and the Social Contribution on Net Income 
(CSLL) in the amount of approximately R$ 56.1 million, and R$ 8.7 million, respectively, which 
relate to the period from January to April 2003, for which the Company offset prior year IRPJ 
and CSLL negative balances. The amounts not ratified by the authority of IRPJ and CSLL are 
R$ 11.2 million and R$ 0.7 million, respectively, totaling R$11.9 million. As the Company 
obtained a partial favorable decision on this matter, the Company´s legal advisors believe 
likelihood of loss amounts to R$ 6.5 million and R$ 1.1 million are possible and probable, 
respectively (R$6.2 million and R$ 1.1 million, respectively, in 2010). 

(g)          The Company filed lawsuits against the Municipalities of Bragança Paulista and São Paulo due 

to the collection by these municipalities of a charge on the use of public areas to install the 
structures used for the water supply and sewage services. In the lawsuit filed against the 
Municipality of Bragança Paulista, the Company granted a preliminary injunction related to this 
charge which prevents the municipality from any current or future of charge collection until is 
the Company reaches a final court decision on this matter. In June 2005, the Company got a 
favorable decision of the lower court and the initial remedy was maintained. The municipality 
appealed against the decision, which has not been decided by the Court of Appeals yet. With 
respect to the Municipality of São Paulo, the Company got an unfavorable decision in the lower 
court which issued a decision confirming the legality of the municipal charge. The Company 
filed an appeal and awaits the judgment. Subsequently, a new law was approved regarding the 
implementation of the collection of a charge on the use of public areas in the Municipality of São 
Paulo. In April 2004, the Company filed an injunction to suspend the collection of the municipal 
charge. The Company had a favorable decision of the lower court, as the injunction was granted 
which recognizes the municipal charge as undue. The municipality filed an appeal, which was 
denied by the Court of Justice. The Company's legal advisors assessed the likelihood of gain on 
this matter as a possible. 

(v)         Labor claims 

The Company is a party to labor lawsuits, involving issues such as overtime, health hazard 
premium and hazardous duty premium, prior notice, change of function, salary equalization, 
and other. Part of the amount involved is in provisional or final execution, assessed the 
likelihood of loss as probable and, consequently, recorded in the financial statements.   

(a)     On January 27, 2005, the São Paulo Water, Sewage and Environmental Workers' Union 

("Sintaema") filed a lawsuit against the Company, claiming compensation for work shifts, which 
was dismissed by the lower court under Company arguments that Sintaema did not have 
legitimacy to file such lawsuit. However, the Labor Regional Court overruled this decision 
favorably to Sintaema and required that the lawsuit returned to the original court for judgment. 
The Company appealed to the Superior Labor Court but did not succeeded. The lawsuit returned 
to the original court and was accepted. The Company appealed but the Labor Regional Court 
maintained the decision and after filed an appeal in the Superior Court, which was not admitted 
and the lawsuit had a final decision and initiate the execution. As of December 31, 2011, the

Amounts in thousands of reais, unless otherwise indicated 

Company's legal advisors assess the likelihood of loss, totaling R$ 62.6 million (R$ 55.9 million 
in 2010), as probable. 

(b)     The São Paulo Water, Sewage and Environmental Workers' Union ("Sintaema") and other 

unions, filed a lawsuit against the Company claiming for, among other matters, over time rate at 
100% and a 1.5% salary increase over inflation for the years of 2010 and 2011. The Labor 
Regional Court decided partially favorably to Sintaema and conceded to the employees over 
time rate at 100%, 1.5% salary increase, and other items. The Company appealed to the Superior 
Labor Court to suspend such decision, which was accepted. Currently, the Company awaits the 
judgment. The Company's legal advisors assess the likelihood of loss, totaling R$ 11.8 million 
(R$ 10.5 million in 2010), as probable. 

(vi)        Environmental claims 

The public civil actions to which the Company is party include the following: 

(a)          Public civil action filed by Paraguaçu Paulista city against SABESP requesting the court to 

sentence the Company to environmental damages caused by the disposal of sewage “in natura”

SABESP in the lower court and the court ordered to: (a) cease the disposal of sewage “in natura” 
in the Alegre River; (b) invest in the water and sewage service system of Paraguaçu Paulista city; 
and (c) indemnity the city for the environmental damages, amounting to R$ 168.9 million. The

penalties. The Company filed an appeal against this decision. On September 21, 2006, the court 
of justice of the state of São Paulo sustained the decision. The Company signed an agreement 
with the Public Prosecutor amounting to R$ 42.7 million lasting 54 months to the execution of 
the investments, R$34.0 million of this amount refers to the compensation of the environmental 
damages. There are some issues related to the accomplishment of the agreement. The 
Company's legal advisors' assessed the likelihood of loss as probable. The amount on December 
31, 2011 corresponds to R$ 43.7 million (R$ 15 in 2010).  

(b)          A public civil action filed by the Public Prosecution Office against SABESP which result was

of the action. SABESP filed an appeal and awaits the decision. As of December 31, 2011, the 
amount provisioned for this claim was R$ 38.4 million (R$ 4.4 million in 2010). The Company's 
legal advisors' assessed the likelihood of loss as probable. 

(c)          Public civil action filed by the Public Prosecution Office against SABESP and the City of Cotia 
seeking individual and joint sentencing of the defendants to: (i) the termination of untreated 
water effluents discharges into the Cotia River or its tributaries, subject to a daily fine in the case

October 17 2006, compensation for environmental damages was R$ 827 or, alternatively, R$ 5.8 
million, if the Company includes the damages caused to the river banks (Cotia river). This

from R$ 3.5 million to R$ 100. As of December 31, 2011, the restated amount of this lawsuit is 
R$ 262 (R$ 9.6 million in 2010). The Company's legal advisors assessed it as a possible loss. 

The Company is a party to other environmental lawsuits in municipalities where it operates, 
arising from the discharge of untreated waste, assessed as probable and possible risks of loss by 
legal advisors. The amounts recognized as provisions do not always represent the final amount 
to be disbursed as indemnity of alleged damages, in view of the current stage in which the such 
lawsuits are and management's ability to reasonably estimate the amounts of future 
disbursements. As of December 31, 2011, total accrued amount represents the R$ 121.2 million 
(R$ 65.1 million in December 31, 2010), already including the amounts referred to in items (a), 
(b), (c) and (d). 

(vii)      Settlements reached in 2011 

In 2011 the Company assigned several settlements related to environmental issues which were 
booked as follows:

(viii)    Other concession-related legal proceedings 

(a)          On March 25, 2005, the municipality of Itapira revoked the concession contract and filed an 

Assets Repossession Action against SABESP. The outcome of this claim was unfavorable to the 
Company. Besides that, was enacted a municipal law which revoke the prior law which 
authorized the municipality to celebrate agreements with SABESP. The Company appealed the 
decision, but in view of the compensation lawsuit filed against the aforementioned municipality, 
the Company has waived the appeal. Company's legal advisors assessed it as a possible gain. 

(b)          The municipality of Cajobi has filed a Repossession Action that seeks the takeover the water 
supply and sewage services, and sentencing the Company to pay for losses and damages for 
amounts received as water and sewage tariffs not received in view of utilities explored since the 
enactment of the Municipal Decree, and for the use of assets related to the concession. The court 
decision confirmed the Municipality's takeover of the water and sewage services. On August 25, 
2008, SABESP filed an appeal which was denied. The Municipality provides water supply and 
sewage collection services since May 29, 2007 under injunction granted in the interlocutory 
appeal. The Company's legal advisors assessed it as a possible gain. 

(c)          The City of Araçoiaba da Serra filed a Repossession Action seeking an authorization to enter 

concession-related facilities, including all properties and chattels linked to the water supply and 
sewage treatment services. The Municipality is now managing and operating these services in 
view of the termination of the concession agreement on September 23, 2006. The Municipality 
also claims the definitive takeover of the services, including due handover of all assets, rights 
and privileges previously transferred to SABESP. The initially granted injunction and confirmed 
by the appellate court maintain the Municipality as the service provider. The decision was 
considered unfavorable for the Company and the Company filed an appeal against this decision. 
The Company's legal advisors assessed it as a possible loss. 

(d)          On July 2, 2010, the City of Tarumã filed a writ of prevention related to all assets related to the 
collection, treatment and water supply and sewage services systems. Initially, the Court 
conceded an injunction, which was reviewed and on January 19, 2011 the Company restarted its 
operation in this municipality. By other injunction decision, the Tarumã municipality requested

the enrollment of assets existing and utilized in the water and sewage services in the 
municipality, determining that the assets will be under SABESP´s custody due to eventual 
liquidation of the indemnity to SABESP. By judicial injunction there was the enrollment of 
assets and SABESP will be the depositary. Both actions are in the phase of knowing and there is 
no definite decision. The Company's legal advisors assessed it as possible and remote loss, 
respectively. 

(e)          In December 2, 1997, the municipality of Santos enacted a law expropriating the Company's 

water and sewerage mains in Santos. The Company requested an injunction against the 
expropriation which was denied by the lower court. This decision was subsequently reversed by 
the State of São Paulo appellate court, which then issued an injunction suspending the law. The 
Company was granted a favorable decision at the lower court, and the municipality of Santos 
appealed against the decision. Although the decision was maintained by the Court of Justice, it 
is not final. Despite the pending action, the Company is operating the water supply and sewage 
collection systems in the municipality of Santos.    The Company's legal advisors assessed it as a 
probable gain. 

(f)           The municipality of Tuiuti has brought a declaratory action seeking to recognize the inexistence 
of  any  judicial  or  legal  grounds  to  justify  our  permanence as the provider  of  water  supply  and 
sewage services in the municipality of Tuiuti, and the subsequent taking over of these services by 
the municipality. The Company responded with a counterclaim against the municipality seeking 
a  statement  corroborating  the  existence  of  a  legal  relationship  between  the  two  parties  for 
subsequent  compensation  for  investments  made.  The  lower  court  decision  was  partially 
unfavorable  to  SABESP  as  it  declared  that  there  was  no  legal  relationship  between  the 
Municipality  and  SABESP  relate  to  the  service  concession  and  confirmed  the  injunction 
authorizing  the  takeover  of  the  services.  However,  the  court's  decision  was  favorable  to  the 
counterclaim  filed  by  SABESP  and  sentenced  the  Municipality  to  pay  R$ 541,  restated  from 
March  1996.  The  Company  filed  an  appeal  on  July  22,  2009.  On  the  other  hand,  the 
Municipality  also  filed  an  appeal.  The  State  Appellate  Court  partially  agreed  with  SABESP  to 
increase  the  indemnity  to  R$  1.1  million  (December/1995).  SABESP  is  not  operating  in  this 
municipality  as  required  by  injunction  granted  to  the  Municipality.  The  Company's  legal 
advisors assessed it as a probable gain. 

(g)          On January 12, 2001, the Company filed an ordinary action against the municipality of 

Presidente Prudente for the purpose of recognizing the contractual right to maintain SABESP as 
the sanitation service until the legal and formal cancellation of the contract, including the 
respective indemnity, which recognizes the abusive and illegal the acts of the municipality. The 
Company still provides sanitation service in Presidente Prudente by judicial decision, which 
extended the concession contract of Presidente Prudente up to the payment of the indemnity. 
The Company's legal advisors assessed it as a remote loss. 

(h)          On March 15, 2011, the Company filed an asset repossession action against the municipality of 

Álvares Florence related to the assets of the concession used in the water and sewage services 
system, including the entire assets related to the water and sanitation services, managing, 
operating and exploring again the services, as prior to the repossession forced by the 
municipality after the period of the contract. In the end request the definitive repossession 
assuring the maintenance of the sanitation services. The decision of the lower court was against 
the Company and the Company appealed against this decision, which is pending. The 
Company’s legal advisors assessed it as possible gain. 

(i)                 On August 19, 2011, the Company filed an asset repossession action against the municipality of 

Macatuba related to the assets of the concession used in the water and sewage services system, 
including the entire assets related to the water and sanitation services, managing, operating and 
exploring again the services, as prior to the end of the contract. The decision of the injunction 
was unfavorable to SABESP and the Company is not operating in this municipality. The action is 
awaiting the decision of the lower court. The Company is also requiring indemnities related to

the investments realized in the municipality which was not amortized. The Company’s legal 
advisors assessed it as possible gain.  

(j)                After the end of the concession contract the municipality of Iperó requested the resumption of 

the services.  On December 30, 2009, the Company filed an asset repossession action against the 
municipality of Iperó requiring the repossession until the payment of the indemnity. Initially, 
the injunction was obtained conceding the Company the maintenance of the operation. After the 
decision in the lower court was unfavorable to SABESP. The Company appealed but there was 
no change in the result. The municipality is operating the services. The action of repossession 
was unfavorable to SABESP and is awaiting the result of the appealed action. The Company is 
also promoting a precautionary action to anticipate proves, in which the injunction was 
conceded to list the assets which belonged to the services. The experts are analyzing the list. The 
Company’s legal advisors assessed it as remote gain.

In 2011, 2010 and 2009, the expense related to the defined benefit obligation under Plan G1 was 
recorded as follows: R$56,613, R$ (24,314) and R$ 51,585 in cost of sales and services, R$ 
8,928, R$ (3,547) and R$ 9,714 in Selling expenses and R$ 8,090, R$ (2,139) and R$ 11,787 in 
Administrative expenses, respectively. 

Curtailment and partial settlement 

As of July, 2010, aiming at resolving the deficit related to the Defined Benefit Plan (G1), SABESP 
and SABESPREV have structured a process through which the participants may elect to move 
from the Defined Benefit Plan to a Defined Contribution Plan, the SABESPREV Mais. 

The migration from plan G1 to SABESPREV Mais resulted in actuarial gain, related to the 
proportional part of the employees who migrated, determined by the present value of the assets 
and liabilities of the pension plan. The Company recognized gain related to curtailment and 
partial settlement of the present value of the defined benefit pension plan and the fair value of 
the plan assets, amounting to R$ 61,377. The Company also recognized prior actuarial gains 
amounting to R$ 15,266. 

The period for the plan migration (from July to November 2010) was suspended through an 
injunctive relief granted by the Court of Justice of the State of São Paulo, on October 20, 2010 
until the claims from the parties involved are taken into consideration. As of October 20, 2010, 
4,023 participants corresponding to 26.0% of the G1 plan migrated to defined contribution plan 
(Sabesprev Mais).

Assumptions regarding future mortality experience are set based on mortality table AT-2000 
(90% of mortality table AT83 in 2010). The change did not cause a relevant impact and this 
table is more adherent to the plan population. 

The discount rate of 5.75% (6.0% in 2010) is similar to the federal public papers rate (NTN-B). 

The number of active participants of G1 as of December 31, 2011 was 9,833 (December 31, 2010

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 law. The plan's asset 
allocation and external asset management strategies are determined with the support of reports

iv) leverage will not be permitted, i.e., operations with derivatives representing leverage of asset 
or selling short are prohibited, such operations cannot result in losses higher than invested 
amounts. 

SABESPREV does not invest in stock or bonds issued by the Company. The investments in loans 
and equity securities are held mainly in investment funds managed by government controlled 
banks. The real estate held in the portfolio is not used by the Company. 

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 fixed rate securities, equity 
securities, real estate, and loans, 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 assets had a return of 14.9% in 2011 and 13.4% in 2010. 

Expected contributions by the Company to Plan G1 for the year ending December 31, 2012 is R$ 
11,018. 

SABESPREV's technical deficit as of December 31, 2011 was R$ 506,431 (December 31, 2010 - 
R$ 437,652). The Company and the SABESPREV are in process of negotiation to resolve the 
technical deficit, by changing the pension plan from a Defined Benefit Plan to Defined 
Contribution Plan. Management expects not to incur in additional costs resulting from the 
change of the referred plans.  

(ii)  Defined Contribution pension plan (SABESPREV MAIS) 

On December 31, 2011, after the migration of the participants, the Defined Contribution Plan 
remained with 4,452 participants (4,023 in 2010). 

With respect to the defined contribution pension plan, the contributions from the sponsor 
represent 100% over the total basic contribution from the participants. 

Regarding the Defined Contribution Plan, the commitment to all participants who migrated up 
to December 31, 2011, as per the actuarial report, amounted to R$ 14,688 relates to all 
participants which migrated. The Company has already made payments in the amount of 
R$ 10,241 in 2011 (R$13,256 in 2010). 

(iii)                      Plan G0 

The Company is also co-obligor to a supplemental defined benefit pension plan. 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 as "Plan G0". The Company pays 
these supplemental benefits on behalf of the State Government and makes claims for 
reimbursements from the State Government, which are recorded as accounts receivable from 
shareholder, limited to the amounts considered virtually certain that will be reimbursed by the 
State Government. As of December 31, 2011, the Company recorded a defined benefit obligation

(e)              Legal reserve 

This reserve is formed by allocating 5% of annual statutory profits until the aggregate amount of 
the reserve equals 20% of our capital stock. However, the Company is not required to make any 
allocations to our legal reserve in a year in which the legal reserve, when added to our other 
established capital and earnings reserves, exceeds 30% of our capital stock. The amounts 
allocated to such reserve may only be used to increase our capital stock or to offset losses. 
Therefore, they are not available for the payment of dividends. 

(f)               Investments reserve 

This is created by allocation of statutory profits in order to fund the expansion of the water 
supply and sewage treatment systems. 

According to Brazilian Law 6404/76, a portion of the net profit of the year can be reserved for 
investment, which amount is based on a budget presented by the management and previously 
approved by shareholders’ meeting. The article of association does not mention about the 
necessity of approval of the budget in the shareholders’ meeting, however the Company adopts 
the rules regarding the Law 6404/76. After concluding the investments, the investment reserve 
will be transferred to capital stock or to retained earnings, in part on in a whole, only after the 
approval of the shareholders. According to Law 6404/76, if a project, which was reserved for 
investment, takes more than one year to be finished, the budget related to such project must be 
approved annually in the shareholders’ meeting, until the conclusion of the project. 

According to article 29 paragraph fourth of the article of association, the Board of Directors can 
propose in a general meeting that the residual profit of the year, after deducting the legal reserve 
and the minimum dividend, can be reserved for investments which will have the following rules:  
I – the amount, add-up by the others earning reserves, may not be higher than the capital stock;  
II – the reserve is used to guarantee the investment plan to be used;  

a)      to absorb losses, when necessary;  
b)      to distribute dividends at any time; 
c)       to rescue, reimburse or acquire stocks, authorized by law; 
d)      to increase capital stock. 

The  investments  reserve  is  specifically  formed  by  the  portion  corresponding  to  own  funds 
assigned  to  the  expansion  of  the  water  supply  and  sewage  treatment  systems,  based  on  the 
budget  approved  by  the  fiscal  counsel.  As  of  December  31,  2011  and  2010,  this  reserve  was 
recognized,  pursuant  to  article  196  of  Law  6404/76,  in  the  total  amount  of  R$ 3,408,591  and 
R$ 2,825,048, respectively.
