PRESENTATION OF FINANCIAL AND OTHER INFORMATION 

General 

We maintain our books and records in reais.  We prepare our financial statements in accordance with 
International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards 
Board, or the IASB.  Our financial statements as of December 31, 2013 and 2012 and for the three years 
ended December 31, 2013 have been audited, as stated in the report appearing herein, and are included in 
this annual report on Form 20-F. 

We restated our financial statements as of and for the years ended December 31, 2012 and 2011 as a 
result  of  the  adoption,  as  of  January  1,  2013,  of  two  new  standards  issued  by  the  IASB:  IAS  19 
(Employee Benefits – as revised in 2011) and IFRS 11 (Joint Arrangements).  These new standards were 
applied retrospectively to 2012 and 2011 pursuant to IAS 8 (Accounting Policies, Changes in Accounting 
Estimates  and Errors) for  comparison purposes.   The adoption  of  these new  standards  impacted  several 
line items of our financial statements.  One of these impacts relates to the method of accounting for the 
results of joint-ventures, which are now recognized using the equity method of accounting instead of the 
proportional  consolidation  method  we  used  prior  to  the  adoption  of  the  IFRS  11.   See  note  4.1  to  our 
financial statements for a description of these standards and their impact on our financial statements.  

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,  2013  was  R$2.3426  to 
US$1.00, which was the commercial rate for the purchase of U.S. dollars in effect on December 31, 2013, 
as reported by the Central Bank.  The U.S. dollar equivalent information presented in this annual report is 
provided solely for the convenience of the 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. 

Other Information 

In  this  annual  report,  unless  the  context  otherwise  requires,  references  to  “we,”  “us,”  “our,” 
“Company,”  or  “SABESP”  refer  to  Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo  – 
SABESP. 

In addition, references to: 

•                     “real,” “reais” or “R$” are to the Brazilian real, the official currency of Brazil; 

•                      “U.S. dollars”  or  “US$”  are  to  the  United  States  dollar,  the  official  currency  of  the  United 

States; 

•                     “Brazil” are to the Federative Republic of Brazil; 

•                     “State” are to the State of São Paulo, which is also our controlling shareholder; 

•                      “federal  government”  and  “Brazilian  government”  are  to  the  federal  government  of  the 
Federative Republic of Brazil and “state government” are to the state government of the State of 
São Paulo; 

  
   
  
•                      “São  Paulo  metropolitan  region,”  with  respect  to  our  operations,  are  to  the  area  where  the 
Metropolitan executive office operates, comprising 37 municipalities, including the city of São 
Paulo; 

 2 

 
•                      “Regional  systems”  are  to  the  area  where  the  Regional  systems  executive  office  operates, 

comprising 326 municipalities in the interior and coastline regions of the State of São Paulo; 

•                     “water coverage ratio” are to the ratio between the number of residences connected to the water 

supply network, divided by the number of urban residences in a certain area; and 

•                      “sewage  coverage  ratio”  are  to  the  ratio  between  the  number  of  residences  connected  to  the 
sewage collection network, divided by the number of urban residences in a certain area. 

Information in this annual report related to liters, water and sewage volumes, number of employees, 
kilometers,  water  and  sewage  connections,  population  served,  operating  productivity,  water  production 
rate,  sewage  lines  (in  kilometers),  savings  achieved  and  investment  in  improvement  programs  has  not 
been audited. 

Market Information 

We make statements in this annual report about our market share and other information relating to 
Brazil and the industry in which we operate.  We have made these statements on the basis of information 
from  third-party  sources  and  publicly  available  information  that  we  believe  is  reliable,  such  as 
information and reports from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de 
Geografia  e  Estatística),  or  IBGE,  and  the  State  Data  Analysis  System  Foundation  (Fundação  Sistema 
Estadual  de  Análise  de  Dados);  or  SEADE,  among  others.   We  have  no  reason  to  believe  any  of  this 
information is inaccurate in any material respect. 

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

Our contracts and the Municipalities We Serve  

Throughout  this  document,  we  refer  to  the  363  municipalities  we  serve  and  to  our  365  water 
contracts.   This  difference  results  from  the  fact  that  we  have  two  partial  water  contracts  with  the 
municipality of Mogi das Cruzes.  These contracts are partial because pursuant to them we serve only two 
neighborhoods  of  this  municipality  and,  as  a  result,  do  not  include  Mogi  das  Cruzes  in  the  total  of 
municipalities we serve.

CAUTIONARY STATEMENTS ABOUT FORWARD-LOOKING STATEMENTS

•                      the  lack  of  formal  agreements  between  our  company  and  certain  municipalities  to  which  we 
provide  water  and  sewage  services,  including  cities  comprising  metropolitan  regions,  and  the 
fact that the State and municipal governments share competency regarding these services; 

•                      the  municipalities’  ability  to  terminate  our  existing  concession  agreements  prior  to  their 

expiration date and our ability to renew such agreements;

the right to provide the services for which we currently have contracts; 

•                     the size and growth of our customer base;

in our agreements with municipalities; 

•                     our level of debt and limitations on our ability to incur additional debt;

•                     the outcome of our pending or future legal proceedings; 

•                     our management’s expectations and estimates relating to our future financial performance; 

  
   
  
 4

ARSESP,  regarding  several  aspects  of  our  business,  including  limitations  on  our  ability  to  set 
and adjust our tariffs;  

•                     the impacts on our business of the water consumption reduction incentive program and of any 
other  measures we may need to take until the level of our reservoirs is normalized and sufficient 
to supply the customers in the São Paulo metropolitan region; 

•                     decisions by the São Paulo State Department of Water and Energy (DAEE) and the National

System,  the  main  water  system  we  use  to  serve  the  São  Paulo  Metropolitan  Region,  and  the 
measures that we may be required to take to ensure the provision of water to our customers; and 

•                     other risk factors as set forth under “Item 3.D. Risk Factors.” 

The  words  “believe,”  “may,”  “estimate,”  “continue,”  “anticipate,”  “plan,”  “intend,”  “expect”  and 
similar  words  are  intended  to  identify  forward-looking  statements.   In  light  of  these  risks  and 
uncertainties,  the  forward-looking  events  and  circumstances  discussed  in  this  annual  report  might  not 
occur.   Our  actual  results  could  differ  substantially  from  those  anticipated  in  our  forward-looking 
statements.   Forward-looking  statements  speak  only  as  of  the  date  they  were  made  and  we  do  not 
undertake any obligation to update or revise any forward-looking statements, whether as a result of new 
information, future events or otherwise, unless required by law.  Any such forward-looking statements are 
not an indication of future performance and involve risks.

ITEM 3.            KEY INFORMATION 
A.         Selected Financial Data 

The  following  selected  financial  data  should  be  read  in  conjunction  with  our  financial  statements 
(including the notes thereto), “Item 5.  Operating and Financial Review and Prospects” and “Presentation 
of Financial and Other Information.” 

The selected financial data as of December 31, 2013 and 2012 and for the years ended December 31, 
2013, 2012 and 2011 have been derived from our financial statements, prepared in accordance with IFRS, 
and  included  in  this  annual  report.   As  described  above  and  in  further  detail  in  note  4.1  to  our  audited 
financial statements, our financial data as of and for the years ended December 31, 2012 and 2011 was 
restated  as  a  result  of  the  retrospective  adoption  of  certain  new  accounting  standards.   The  selected 
financial  data  as  of  and  for  the  years  ended December 31,  2010  and  2009  have  been  derived  from  our 
financial  statements,  prepared  in  accordance  with  IFRS,  which  is  not  included  in  this  annual  report.  
Because these financial statements, and the financial data derived therefrom, were not restated to reflect 
the adoption of the new standards described above, they are not comparable to our financial statements, 
and  the  financial  data  derived  therefrom,  as  of  and  for  the  years  ended  December  31,  2013,  2012  and 
2011 (see note 4.1 to our audited financial statements).  

We  have  included  information  with  respect  to  the  dividends  and/or  interest  attributable  to 
shareholders’  equity  paid  to  holders  of  our  common  shares  since  January 1,  2009  in  reais  and  in  U.S. 
dollars translated from reais at the commercial market selling rate in effect as of the payment date under

(2)    On  April  22,  2013,  our  shareholders  approved  a  stock  split,  following  which  each  common  share  represented  three  new

Mogi Mirim S/A, Águas de Andradina, Águas de Castilho, Saneaqua Mairinque, Aquapolo Ambiental and Attend Ambiental 
are recognized using the equity method of accounting in 2013, 2012 and 2011 rather than through proportional consolidation 
as previously. 

(4)   Data for 2010 and 2009 have not been restated in application of IAS 19 – Employee Benefits (as revised in 2011) and IFRS 11 
– Joint Arrangements, described in note 4.1 to our financial statements. In particular, data for 2010 and 2009 reflect the results 
of  the  joint-ventures  Sesamm  –  Serviços  de  Saneamento  de  Mogi  Mirim  S/A,  Águas  de  Andradina,  Águas  de  Castilho, 
Saneaqua  Mairinque,  Aquapolo  Ambiental  and  Attend  Ambiental  through  proportional  consolidation  in  2010  and  2009,  as 
opposed to the equity method of accounting applicable in 2013, 2012 and 2011.  

(*)   On January 10, 2013, the ratio of American Depositary Receipts (“ADRs”) to common shares changed from 1:2 to 1:1.  We 
have adjusted the earnings per ADS and dividends and interest on shareholders’ equity per ADS for prior years for comparison 
purposes on the table above.

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  the  ability  of  Brazilian  residents  to  acquire  foreign 
currency,  among  others.   On  March 24,  2010,  the  CMN  and  the  Central  Bank  approved  Resolution 
No. 3,844,  which  led  to  a  series  of  measures  to  consolidate  and  simplify  Brazilian  foreign  exchange 
market regulations. 

The Brazilian foreign exchange system allows any person or legal entity to purchase or sell foreign 
currency and make international transfers of reais, regardless of the amount, subject to certain regulatory 
procedures. 

The  Brazilian  currency  has  experienced  frequent  and  substantial  variations  in  relation  to  the 
U.S. dollar  and  other  foreign  currencies  in  recent  decades.   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.   The  real   strengthened  again  by 
25.5%  in  2009  and  4.3%  in  2010,  but  depreciated  against  the  U.S. dollar  by  12.6% in  2011,  8.94%  in 
2012 and 14.63% in 2013. On December 31, 2013, 2012 and 2011, the real/U.S. dollar exchange rate was 
R$2.3426, R$2.0435 and R$1.8758 per US$1.00, respectively. 

The  Central  Bank  sometimes  intervenes  in  the  market  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  other 
procedure.   The  real  may  fluctuate  against  the  U.S. dollar  substantially  in  the  future.   For  further 
information on this risk, 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.”

Exchange  rate  fluctuations  will  affect  the  U.S. dollar  equivalent  of  the  real  price  of  our  common 
shares  on  the  São  Paulo  Stock  Exchange  (BM&FBOVESPA  S.A.  -  Bolsa  de  Valores,  Mercadorias  e

reais with respect to our common shares.

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, changes in interest rates, tax 
policies,  price  and  tariff  controls,  currency  devaluation  or  appreciation,  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: 

•                     the regulatory environment related to our business operations and concession agreements; 

•                     interest rates; 

•                     exchange rates and exchange controls and restrictions on remittances abroad; 

•                     currency fluctuations; 

•                     inflation;  

•                     liquidity of the Brazilian capital and lending markets; 

•                     tax and regulatory policies and laws; 

•                     economic and social instability; and 

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

For  example,  the  Brazilian  government  may  change  its  tax  policy,  such  as  changing  tax  rates  or 
imposing temporary taxes.  If overall taxes are increased, we may be unable to immediately recover the 
difference from our consumers, which may have an adverse effect on our financial condition and results 
of operations.  

Uncertainty over whether the Brazilian government will implement changes in policies or regulations 
affecting  these  factors  or  others  may  contribute  to  economic  uncertainty  in  Brazil  and  to  heightened 
volatility  in  the  Brazilian  securities  market  and  in  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  experienced  extremely  high  rates  of  inflation  in  the  past.   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 

  
   
  
market.  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, equaled 9.90%, 7.14% and 10.91% at 
the end of 2013, 2012 and 2011, respectively, in line with the target rate set by the Brazilian Committee 
on Monetary Policy (Comitê de Política Monetária).    

 10 

 
The Brazilian annual inflation rates, as measured by the General Market Price Index (Índice Geral de 
Preços—Mercado),  or  IGP-M  index,  were  5.51%,  7.81%  and  5.1%  during  2013,  2012  and  2011, 
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 experiences high inflation again, 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 decrease 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 decades leading up to the mid-1990s.  Throughout this 
period,  the  Brazilian  government  implemented  various  economic  plans  and  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 since that period, there have continued to be 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, primarily as a result of the global financial crisis, the real depreciated 32.0% against the U.S. dollar 
and closed the year at R$2.337 per US$1.00.  The real  strengthened again by 25.5% in 2009 and 4.3% in 
2010, but depreciated against the U.S. dollar by 12.6% in 2011, 8.94% in 2012 and 14.63% in 2013. On 
December 31,  2013,  2012  and  2011,  the  real/U.S. dollar  exchange  rate  was  R$2.343,  R$2.043  and 
R$1.876 per US$1.00, respectively.  There can be no assurance that the real will not depreciate further 
against the U.S. dollar.  As of April 16, 2014, the commercial selling rate as reported by the Central Bank 
was R$2.2342 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  our  access  to  financial  markets  and 
prompt government intervention, including recessionary governmental policies.  Depreciation of the real 
against  the  U.S. dollar  could  also  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 because our 
tariff revenue and other sources of income are denominated solely in reais.  In addition, because we have 
debt denominated in foreign currencies, any significant devaluation of the real will increase our financial 
expenses  as  a  result  of  foreign  exchange  losses  that  we  must  record.   We  had  a  total  foreign  currency 
denominated  debt  of  R$3,698.6  million  as  of  December 31,  2013  and  we  anticipate  that  we  may  incur 
additional amounts of foreign currency denominated debt in the future.  In 2013, our results of operations 
were  negatively  affected  by  the  14.64%  depreciation  of  the  real  against  the  U.S. dollar,  and  an 
appreciation of the real against the yen by 5.91% which led to a R$267.8 million negative impact on our 
foreign exchange result, net.  We do not currently have any derivative 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.  

11 

  
   
  
 
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.   Crises  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 caused 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 the interests of non-

controlling, including holders of ADSs.  

As  it  owns  the  majority  of  our  common  shares,  the  State  of  São  Paulo  is  able  to  determine  our 
operating policies and strategy, control the election of a majority of the members of our board of directors 
and  appoint  our  senior  management.   As  of  April  16,  2014,  the  State  owned  50.3%  of  our  outstanding 
common shares.  Both through its control of our board of directors as well as by enacting State decrees, 
the State has in the past directed our company to engage in business activities and make expenditures that 
promoted political, economic or social goals but that did not necessarily enhance our business and results 
of  operations.   The  State  may  direct  our  company  to  act  in  this  manner  again  in  the  future.   These 
decisions by the State may not be in the interests of our non-controlling, including holders of ADSs.  See 
“Item 5.A.  Operating  and  Financial  Review  and  Prospects—Certain  Transactions  with  Controlling 
Shareholder.” 

Following the elections for State governor in 2010, the new governor appointed Ms. Dilma Seli Pena 
as our chief executive officer in 2011 at the meeting of the board of directors held on January 27, 2011.  
In late March 2014, Mr. Alberto Goldman temporarily assumed the position of chairman of the board of 
directors.   The  new  chairman  of  the  board  of  directors  will  be  elected  for  a  term  of  two  years  at  the 
shareholders’ meeting to be held on April 30, 2014.  Future changes in policy by State government may 
cause  changes  in  all  or  some  of  the  members  of  our  management,  which  may  have  a  material  adverse 
effect on our business and results of operations. 

The  State  and  some  State  entities  owe  us  substantial  unpaid  debts.   We  cannot  assure  you  as  to 

when or whether the State will pay us. 

Historically, the State and some State entities have delayed payment of substantial amounts owed to 
us related to water and sewage services. Additionally, the State also owes us substantial amounts related 
to reimbursements of 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,  2013,  the 
State  owed  us  R$63.9  million  for  water  and  sewage  services.   With  respect  to  payment  of  pensions  on 
behalf of the State, we had a non-contested reimbursement credit in the amount of R$179.1 million as of 
December 31, 2013 for actuarial liability, and a contested credit amount of R$1,412.5 million as of the 
same date.  We do not record this contested amount as a reimbursement credit for actuarial liability due to 
the uncertainty of payment by the State.  In addition, as of December 31, 2013, we had a provision for an 
actuarial liability in the amount of R$1,780.3 million in respect of future supplemental pension payments 

  
   
  
the State does not accept responsibility for paying.  The amounts owed to us by the State for water and 
sewage services and reimbursements for pensions paid may increase in the future. 

12 

 
We have entered into agreements with the State to settle the overdue amounts that relate to water and 
sewage  services.   For  a  detailed  discussion  of  these  agreements,  see  “Item 7.B.  Related  Party 
Transactions, Agreements with the State of São Paulo” and Note 9 of our financial statements.   

We cannot assure you when or if the State will pay the remaining overdue amounts it owes us.  Due 
to  the  State’s  history  of  not  paying  us  in  a  timely  manner  for  water  and  sewage  services,  and  not 
reimbursing us in a timely manner for the pension benefits we paid on its behalf, we cannot assure you 
that  the  amount  of  account  receivables  owed  to  us  by  the  State  and  some  State  entities  will  not 
significantly increase in the future. 

In  addition,  certain  municipalities  and  other  government  entities  also  owe  us  money.   See  “Risks 
Relating  to  Our  Business—We  may  face  difficulties  in  collecting  overdue  amounts  owed  to  us  by 
municipalities to which we provide water on a wholesale basis and municipal government entities.”   

A  state  controlled  company  that  has  a  concession  to  produce  energy  in  the  Guarapiranga  and 

Billings reservoirs may require us to pay damages for the use of water from these reservoirs.  

Empresa  Metropolitana  de  Águas  e  Energia  S.A.,  or  EMAE,  may  require  us  to  financially 
compensate them for our use of water from the Guarapiranga and Billings reservoirs, which they view as 
a  loss  of  electricity  that  could  otherwise  be  generated  and  sold.  As  such,  EMAE  has  requested 
compensation from us. In the event water from these reservoirs were no longer made available to us, we 
would have to bring water in from locations farther away, which would increase the risk of not being able 
to provide adequate service in the region and increase the costs of water transportation. 

The  majority  shareholder  of  both  EMAE  and  us,  the  State  of  São  Paulo,  may  force  a  resolution 
regarding  the  dispute  of  water  use  from  the  Guarapiranga  and  Billings  reservoirs,  which  may  have  an 
adverse  effect  on  our  business.  Currently,  this  matter  is  under  judicial  review  due  to  various  actions 
brought by EMAE.  On April 10, 2014, we issued and Announcement to the Market to communicate that 
we are negotiating with EMAE regarding a potential future agreement.  However, no adjustment has been 
confirmed and no agreement has been executed by either party as of yet.   

Additionally,  in  the  event  we  are  required  to  make  payments  and  compensation,  our  cash  position 

and overall liquidity may be adversely affected. 

We may be required to pay substantial charges for the use of reservoirs that are not our property. 

We use the Billings and Guarapiranga reservoirs in order to provide water services.  We are entitled 
to withdraw water from these reservoirs under a grant from  the State Department of Water and Energy 
(Departamento  de  Águas  e  Energia  Elétrica do Estado  de  São  Paulo), or DAEE. We  are not  currently 
charged for the use of these reservoirs and 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 one were imposed.   

We  may  also  be  required  to  pay  additional  maintenance  and  operational  costs  for  our  use  of 
reservoirs.  If we were required to pay substantial charges or additional maintenance or operational costs 
for our use of these reservoirs, we could be materially and adversely affected.  

Risks Relating to Our Business  

Current regulatory uncertainty, especially with regard to implementation and interpretation of 

the Brazilian Basic Sanitation Law, may have an adverse effect on our business. 

The  Basic  Sanitation  Law  No.  11,445  went  into  effect  in  early  2007,  and  although  in  2010 
Federal  Decree  No.  7,217  (as  modified  by  Federal  Decree  No.  8,211/14)  implemented  a  first  series  of 
new  principles  under  the  Basic  Sanitation  Law,  the  full  implementation  of  a  number  of  its  provisions 
remains subject to regulations that the federal government has not yet published.  As a result, we cannot 
currently anticipate all the effects that the Basic Sanitation Law and the decree will have on our business 
and operations, if any.  

  
   
  
   
The  Basic  Sanitation  Law  requires  states  to  establish  independent  regulators  with  the 
responsibility  of  monitoring  basic  sanitation  services  and  regulating  tariffs,  and  in  response  São  Paulo 
State  established  in  2007  the  São  Paulo  State  Sanitation  and  Energy  Regulatory  Agency  (ARSESP), 
which regulates  and  supervises  the basic sanitation  services  that we provide  in  municipalities  that  have 
agreed to come under ARSESP’s jurisdiction.   

13 

 
In  2009,  ARSESP  enacted  rules  regarding  the  following:  (i)  general  terms  and  conditions  for 
water and sewage services; (ii) procedures for communication regarding any failure in our services; (iii) 
penalties for deficiencies in the provision of basic sanitation services; and (iv) procedures for confidential 
treatment of our customers’ private information. The implementation of these and other more recent rules 
will particularly impact our commercial and operations processes, and may adversely affect us in ways 
we cannot currently predict.  Implementation of these rules started in 2011 and is expected to continue for 
the next few years. For more information, see “Item 4.B. Business Overview—Government Regulation—
ARSESP Rule Enactments”. 

In 2011, ARSESP altered the standard contract that we are required to use in our relationships 
with retail customers.  This alteration requires that invoices be sent to the consumer of the service rather 
than  the  owner  of  the  property.   We  estimate  that  this  change  will  affect  ongoing  legal  disputes, 
particularly those regarding collection procedures, as well as business discussions in general.  However, 
since  this  change  is  still  being  implemented,  we  are  not  currently  able  to  predict  its  impact  on  our 
business.  

The  Basic  Sanitation  Law  also  allows  municipalities  to  create  their  own  regulatory  agencies 
rather than being regulated by ARSESP.  As a result, a number of municipalities have created their own 
regulatory agencies.  If other municipalities create new agencies or retain regulatory powers, we will be 
subject  to  their  regulation  and  to  any  limitations  on  our  services  that  such  agencies  may  set.   We  are 
involved in legal proceedings that dispute the authority of these new agencies to regulate us.  We cannot 
foresee  any  changes  that  any  such  new  agencies  may  implement  regarding  our  business.   If  any  such 
changes are unfavorable, they could materially and adversely affect us. 

For  more  information  on  ARSESP  regulations,  see  “Item  4.B.  Business  Overview—Tariff 
Government Regulation—Tariff Regulation in the State of São Paulo” and “ARSESP Rule Enactments—
Consumer Relations in the State of São Paulo.” 

New  joint  entities  have  been,  and  may  continue  to  be,  set  up  to  oversee  basic  sanitation 
services in metropolitan regions, including the São Paulo metropolitan region.  We cannot predict how 
the shared management of these operations will be carried out in the São Paulo metropolitan region 
and  other  metropolitan  regions  we  operate  or  what  effect  this  may  have  on  our  business,  financial 
condition or results of operations. 

There  are  some  pending  cases  before  the  Brazilian  Supreme  Court  regarding  whether  the  right  to 
execute concession and program agreements in metropolitan regions belongs to the State or the municipal 
government.  On February 28, 2013, the Brazilian Supreme Court decided a pending case on this matter 
related to the State of Rio de Janeiro.  A majority of the court held that the State of Rio de Janeiro and its 
municipal governments must set up new joint entities to oversee the planning, regulation and auditing of 
basic  sanitation  services  in  metropolitan  regions.   On  March 6,  2013,  the  court  ruled  that  this  decision 
would come into effect after a 24-month period over the State of Rio de Janeiro.  Such decision may be 
considered  a  relevant  precedent  on  this  matter  and  therefore  similar  decisions  may  be  taken  on  other 
pending  cases  as  well  as  on  new  cases  that  can  be  initiated.   The  Supreme  Court  has  yet  to  clarify  the 
effects and extension of its decision. The São Paulo metropolitan region (including the municipalities to 
which we provide water on a wholesale basis), one of which new decisions on such pending or new cases 
may apply, accounted for 73.2% of our gross revenue from services in 2013 (excluding revenues relating 
to the construction of concession infrastructure).  We cannot predict how the shared management of these 
operations could be carried out in the São Paulo metropolitan region and other municipalities we operate 
or what effect it may have on our business, financial condition or results of operation. 

The terms of our agreement to provide water and sewage services in the City of São Paulo could 

have a material adverse effect on us. 

The  provision  of  water  and  sewage  services  in  the  City  of  São  Paulo  accounted  for  53.6%  of  our 
gross operating revenues (excluding revenues relating to the construction of concession infrastructure) in 
the year ended December 31, 2013. 

 14 

  
   
  
 
On  June 23,  2010,  the  State  and  the  City  of  São  Paulo  executed  an  agreement  in  the  form  of  a 
convênio,  to  which  we  and  ARSESP  consented,  under  which  they  agreed  to  manage  the  planning  and 
investment for the basic sanitation system of the City of São Paulo on a joint basis.  The principal terms 
of this convênio  were as follows: 

•                     The State and the City of São Paulo would execute a separate agreement with us, granting us 

exclusive rights to provide water and sewage services in the City of São Paulo. 

•                     ARSESP would regulate and oversee our activities regarding water and sewage services in the 

City of São Paulo, including tariffs. 

•                      A  management  committee  (Comitê  Gestor)  would  be  responsible  for  planning  water  and 
sewage  services  for  the  City  and  for  reviewing  our  investment  plans.   The  management 
committee consists of six members appointed for two-year terms.  The State and the City of São 
Paulo  have  the  right  to  appoint  three  members  each.   We  may  participate  in  management 
committee meetings but may not vote. 

In  application  of  the  convênio,  we  executed  a  separate  contract  with  the  State  and  the  City  of  São 
Paulo,  also  dated  June 23,  2010,  to  regulate  the provision of  these  services  for  the  following  30  years.  
The principal terms of this contract are as follows: 

•                      The  total  investment  stated  in  the  contract  must  be  equal  to 13%  of  gross  revenues from  the 
provision  of  services  to  the  City  of  São  Paulo,  net  of  the  taxes  on  revenues,  which  total 
approximately R$600 million per year. 

•                      We  must  transfer  7.5%  of  the  gross  revenues  we  derive  under  the  convênio,  and  subtract 
(i) COFINS  and  PASEP  taxes,  and  (ii) unpaid  bills  of  publicly  owned properties  in  the  city  of 
São  Paulo,  to  the  Municipal  Fund  for  Environmental  Sanitation  and  Infrastructure  (Fundo 
Municipal  de  Saneamento  Ambiental  e  Infraestrutura),  established  by  Municipal  Law 
No. 14,934/2009.   

•                     Our investment plan must be compatible with the sanitation plans of the State, the City of São 

Paulo and, if necessary, the Metropolitan region. 

•                     ARSESP will ensure that the tariffs will adequately compensate us for the services we provide 
and  that  tariffs  may  be  adjusted  in  order  to  restore  the  original  balance  between  each  party’s 
obligations and economic gain (equilíbrio econômico-financeiro).   

We  currently  have  an  investment  plan  in  place  that  reflects  these  obligations  and  addresses  their 
compatibility with the sanitation plans for municipalities in which we operate, including the City of São 
Paulo and the Metropolitan region.  The investment plan is not irrevocable and will be reviewed by our 
management committee every four years, particularly with respect to the investments  to be executed in 
the subsequent period. 

Because we were not previously required to transfer 7.5% to the São Paulo Municipal Sanitation and 
Infrastructure Fund as described above, our existing tariff and adjustment formulas do not account for this 
requirement.  Nonetheless,  ARSESP  is  required  to  ensure  that  the  tariffs  will  adequately  compensate  us 
for the services we provide, which includes the pass-through to tariffs. 

•                     In April 2013, ARSESP issued Resolution No. 407 authorizing us to pass through to the service 
bill the 7.5% transfer to the São Paulo Municipal Sanitation and Infrastructure Fund as a legal 
charge, as defined by municipal legislation.  Pursuant to the Program Contracts and the Sewage 
and Water Supply Service Contracts, this charge must be considered in the tariff revision. 

•                      In  April 2013,  ARSESP  issued  Resolution  No. 413,  which  effectively  suspended  Resolution 
No. 407  until  the  tariff  revision  process  is  concluded,  thereby  postponing  our  authorization  to 
pass the charge through to consumers on the service bill. The postponement of Resolution No. 
407 was due to a request from the São Paulo State Government to analyze, among other things, 

  
   
  
methods  of  reducing  the  impact  on  consumers.   Although  Resolution  No.  407  establishes  the 
conclusion of the tariff review as the date for the implementation of the pass-through, we cannot 
be certain when Resolution No. 407 will be implemented.  

15 

 
•                      In  April  2014,  ARSESP  issued  Resolution  No. 484,  which  establishes  the  conclusion  of  the 
tariff revision.  No decision was made in relation to the 7.5% charge to our consumers, and we 
do not know when a final decision will be reached.  We cannot know when we will be able to 
pass the 7.5% charge to consumers on the service bill. 

Since 2010, we have transferred approximately R$ 1.1 billion to the São Paulo Municipal Sanitation 
and Infrastructure Fund, as of December 2013.  We cannot assure you when and how we will recover this 
amount. 

We  cannot  assure  you  that  this  charge  will  eventually  be  passed  through  to  customers  or  that  the 
continued delay in passing on the charge to customers will not affect our financial condition.  For further 
information  on  ARSESP  regulations,  see  “Item  4.B.  Business  Overview—Government  Regulation—
Tariff  Regulation  in  the  State  of  São  Paulo”  and  “Government  Regulation—Public  Consortia  and 
Cooperation Agreement Law for Joint Management.”  

We  currently  lack  formal  agreements  or  concessions  with  61  of  the  municipalities  to  which  we 
provide service, and 38 of our existing concession agreements will expire between 2014 and 2034.  We 
may face difficulties in continuing to provide water and sewage services in return for payment in these 
and other municipalities, and we cannot assure you that they will continue to purchase services from 
us on the same terms or at all. 

As of December 31, 2013, we held formal 30-year agreements with 265 municipalities (including the 
City of São Paulo) of the 363 municipalities we serve.  We executed 7 of these agreements during 2013.  
The  265  municipalities  with  which  we  had  formal  agreements  at  year-end  accounted  for  72.9%  of  our 
total  revenues  for  the  year  ended  December 31,  2013,  and  64.6%  of  our  intangible  assets  as  of 
December 31, 2013.  Of the 61 served municipalities for which we lacked formal agreements at year-end, 
we  were  in  the  process  of  actively  renegotiating  with  all  municipalities,  including  the  municipality  of 
Santos.  Together, these 61 municipalities accounted for 16.1% of our total revenues for the year ended 
December 31, 2013 and 25.1% of our intangible assets as of that same date.  Between 2014 and 2034, 38 
of our existing concession agreements will expire.  These 38 concession agreements accounted for 9.0% 
of our total revenues for the year ended December 31, 2013 and 8.0% of our intangible assets as of that 
same date. 

We may not be able to continue providing service on current terms, or at all, in the municipalities for 
which  we  do  not  have  formal  agreements,  including  the  61  for  which  we  are  renegotiating  expired 
agreements.   In  particular,  the  lack  of  formal  concessions  or  contractual  rights  in  these  municipalities 
means  that  we  may  not  be  able  to  enforce  our  right  to  continue  to  provide  services  and  we  may  face 
difficulties in being paid on a timely basis, or at all, for the services that we provide.  If we are successful 
in  renegotiating  the  expired  agreements,  or  executing  formal  agreements  with  the  municipalities  for 
which we have never had agreements, those agreements may not contain terms that are as favorable as 
those  under  which  we  currently  operate.   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  ARSESP.   The  municipalities  for  which  we  do  not  have 
formal agreements may choose to start providing water and sewage services directly themselves, or may 
run public tenders to select another provider.  They may set eligibility requirements for which we do not 
qualify and, if we do qualify and participate in these tenders, we may not win.  In addition, our ability to 
continue  operating  without  formal  agreements  may  be  modified  or  cancelled  by  federal,  state  or 
municipal governments, court decisions or other factors. 

Any of these events could have a material adverse effect on our business, results of operations and 
financial  condition.   See  “Item 4.B.  Business  Overview—Our  Operations”  and  “Government 
Regulation—Public Consortia and Cooperation Agreement Law for Joint Management.” 

In  the  municipalities  with  which  we  did  not  have  formal  agreements  by  December 31,  2013,  we 

continued operating with municipal approval or with judicial support.  

  
   
  
  
The  municipalities  may  terminate  our  concessions  before  they  expire  in  certain  circumstances.  
The indemnification payments we receive in such cases may be less than the value of the investments 
we made.  

The  municipalities  have  the  right  to  terminate  our  concessions  if  we  fail  to  comply  with  our 
contractual or legal obligations, or if the municipality determines in expropriation proceedings that early 
termination of the concession is in the public interest.  If a municipality terminates our concession, we are 
entitled to be indemnified for the unamortized portion of our investments.   

 16 

 
The Basic Sanitation Law provides that on early termination of a concession, the entity that provides 
sanitation services should carry out a valuation of the assets that relate to the services we provide, in order 
to  calculate  the  unamortized  portion  of  our  investments.   This  valuation  uses  the  criteria  defined  in  the 
service  contract  or,  in  the  absence  of  a  contract,  is  based  on  customary  practice  with  respect  to  the 
services  for  the  preceding  20  years.   The  resulting  indemnification  payment  may  be  less  than  the 
remaining value of the investments we made.   

In addition, the São Paulo State constitution permits the municipalities to pay us this compensation in 
installments  over  25  years.   Receiving  compensation  over  this  extended  period  after  termination  of  a 
significant  concession  would  have  a  material  adverse  effect  on  our  financial  condition.   The  Brazilian 
Supreme Court suspended this deferred payment mechanism in a 1997 decision, but we cannot assure you 
that the mechanism will not be reinstated.  This case is still awaiting a final decision, but on March 15, 
2004  the  Attorney  General  issued  an  opinion  that  this  payment  method  is  unconstitutional.   The  Basic 
Sanitation Law reduced the maximum time period for payment of indemnification in such cases to four 
years.  This provision applies to concession agreements entered into prior to the enactment of the Basic 
Sanitation  Law  only  to  the  extent  that  the  concession  agreement  does  not  contain  a  contractual 
indemnification provision, or we have not otherwise entered into an agreement with the municipality with 
regard  to  such  early  termination.   These  provisions  have  not  yet  been  tested  by  the  courts  and  we  are 
therefore unable to predict the effect of the Basic Sanitation Law on our rights to indemnification for the 
early termination of any particular concession. 

In 1997, the municipality of Santos enacted a law in order to repossess our water and sewage systems 
in Santos.  We have adopted the necessary judicial measures to contest this and continue to operate our 
services in Santos as of December 31, 2013. We filed an ordinary suit against the municipality of Santos, 
and  our  operation  is still  in  place.  The appellate  court  issued  a decision  that  is  favorable  to us,  and we 
consider the risk of loss as remote.  

In 1995, the municipality of Diadema terminated its concession agreement with us.  We commenced 
legal  proceedings  against  the  municipality,  which  were  settled  in  1996,  but  the  municipality  did  not 
comply  with  the  terms  of  the  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,  previously  known  as  the  State  Secretariat  for  Sanitation  and  Energy 
(Secretaria  de  Saneamento  e  Energia  do  Estado  de  São  Paulo).   Under  this  memorandum  of 
understanding  the  parties  agreed  to  conclude  negotiations  and  settle  all  outstanding  amounts,  and  we 
agreed  to  stay  the  collection  proceedings  we  had  filed  against  the  municipality.   In  2011,  we  and  the 
municipality of Diadema agreed to develop shared infrastructure for water and sewage services through a 
mixed  capital  company  to  be  called  Companhia  de  Água  e  Esgoto  de  Diadema,  or  CAED.   Studies 
regarding  the  establishment  of  CAED  have  been  discontinued,  and  on  March  18,  2014,  we  executed  a 
contract  to  resume  direct  supply  of  water  and  sewage  services  to  the  municipality  of  Diadema.  
Concurrently,  we  entered  an  agreement  with  Diadema  to  resolve  water  supply-related  debt  and 
indemnities.  Guarantees are in place if the municipality of Diadema breaches its agreement with us. 

Other  municipalities  may  seek  to  terminate  their  concession  agreements  before  the  contractual 
expiration date.  If this occurs and we do not receive adequate indemnification for our investments, or the 
indemnification is paid over an extended period, we may suffer material harm to our financial position. 

We may face difficulties in collecting overdue amounts owed to us by municipalities to which we 

provide water on a wholesale basis and municipal government entities. 

As  of  December 31,  2013,  our  total  accounts  receivable  was  R$4,372.2  million.   Of  this  amount, 
certain municipalities to which we provide water on a wholesale basis owed us R$1,917.9 million, and 
certain  municipal  government  entities  owed  us  R$679.6  million.   Of  the  total  amount  owed  by 
municipalities,  R$205.2  million  was  overdue  by  between  30  and  360 days  and  R$1,645.3  million  was 
overdue by over 360 days. 

The  Brazilian courts  are  entitled  to  obligate  us  to  continue  to  supply  water  to  these municipalities, 
even when we have not received payments due to us.  We have no way of ensuring that negotiations with 
these municipalities or legal action taken against the municipalities will result in payments being made.  

  
   
  
Some  entities  associated  with  municipal  governments  for  which  we  provide  services  also  do  not  make 
regular payments.  We cannot guarantee if or when these entities will make payments on a regular basis 
or pay the amounts owed to us.  If the municipalities and related entities do not pay the amounts owed to 
us, we may suffer material harm to our financial position.   

17 

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

expenditure program. 

Our capital expenditure program will require resources of approximately R$12.8 billion in the period 

from 2014 through 2018.  In 2013 we recorded R$2.7 billion in capital expenditures. 

We  have  funded  these  capital  expenditures  with  cash  generated  by  our  operations  as  well  as 
borrowings  in  Brazilian  reais   and  foreign  currencies,  and  we  intend  to  continue  to  fund  our  capital 
expenditures from these sources.  A significant portion of our financing needs has been provided by the 
Brazilian federal public government banks.  We have obtained long-term financing at attractive interest 
rates from multilateral agencies and domestic and international governmental development banks.  If the 
Brazilian government changes its policies regarding the financing of water and sewage services, or if we 
fail to obtain long-term financing at attractive interest rates from domestic and international multilateral 
agencies and development banks in the future, we may not be able to meet our obligations or finance our 
capital  expenditure  program,  which  could  have  a  material  adverse  effect  on  our  business  and  financial 
condition. 

Governmental agencies, institutional lenders and multilateral agencies constitute our main sources of 
financing in addition to cash generated by our operations and issuances of debt securities in the domestic 
and  international  capital  markets.   Brazilian  financial  institutions  are  legally  limited  up  to  a  certain 
percentage  of  their  shareholder’s  equity  to  provide  loans  to  public  sector  entities,  such  as  us.   These 
limitations could adversely affect our ability to continue our capital expenditure program. 

Our  debt  includes  financial  covenants  that  impose  indebtedness  limits  on  us,  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  seriously  impair  our  ability  to  finance  our  capital  expenditure 
program, which could have a material adverse effect on us. 

Compliance with environmental laws and environmental liability payments could have a material 

adverse effect on us. 

We 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 set potable water standards 
and  limit  or  prohibit  the  discharge  or  spillage  of  effluent  produced  in  our  operations,  particularly  raw 
sewage.  We occasionally suffer accidents such as leakages or breaks in pipes that could lead to liability 
for damages under environmental law.  We could be subject to various types of criminal, administrative 
and civil proceedings for non-compliance with environmental laws and regulations, which could expose 
us  to  penalties  and  criminal  sanctions,  such  as  fines,  closure  orders  and  significant  indemnification 
obligations.   The  scope  and  enforcement  of  environmental  laws  in  Brazil  are  becoming  more  stringent, 
and our capital expenditures and environmental compliance costs may increase substantially as a result.  
These  expenses  may  lead  us  to  reduce  expenditure  on  strategic  investments,  which  could  harm  our 
business.  In addition, Brazilian courts are enforcing environmental laws more stringently than in the past, 
which  may  result  in  fines  or  liability  for  damages  that  are  significantly  higher  than  those  we  currently 
anticipate.  We are party to various environmental proceedings that could have a material adverse impact 
on  us,  including  civil  processes  and  investigations  relating  to  the  release  of  untreated  sewage  into 
waterways  and  the  disposal  of  sludge  generated  by  treatment  plants.   Any  unfavorable  judgment  in 
relation to these proceedings, or any  material unforeseen environmental  liabilities,  may have a material 
adverse effect on us.  For further information on these proceedings, see “Item 8.A. Financial Information 
– Financial Statements and Other Financial Information – Legal Proceedings.” For further information on 
investments  in  environmental  programs,  see  “Item  4.A  -  Main  Projects  of  our  Capital  Expenditure 
Program,”  “Item  4.B  –  Business  Overview  –  Sewage  Treatment  and  Disposal  ,”  “Item  4.B  –  Business 
Overview - Environmental Matters” and “Item 4.B – Business Overview - Environmental Regulation.” 

  
   
  
New laws and regulations relating to climate change and changes in existing regulation, as well as 
the  physical  Effects  of  Extreme  Weather  Events,  may  result  in  increased  liabilities  and  increased 
capital expenditures, which could have a material adverse effect on us. 

Current federal, state and municipal laws and regulations on climate change establish global goals, 
which we intend to meet, concerning greenhouse gas emissions and this may require us to increase our 
investments  in  order  to  comply  with  these  laws.  Currently,  however,  if  we  increase  our  capital 
expenditures for this purpose, we may be required to reduce expenditures on other strategic investments. 

18 

 
In  addition,  climate  change  may  lead  to  increases  in  extreme  weather  events  such  as  droughts  or 

torrential rain, which may affect our ability to deliver our services and require us to take action such as: 

•                     investing in seeking new water sources located further from major consumer centers; 

•                     investing in new technologies; 

•                      improvement  of  water  conservation  practices  and  demand  management  alternatives  such  as 

economic mechanisms or educational programs; and  

•                     increasing our reserve capacity. 

An increase in sea levels could cause additional intrusion of salt water in the river estuaries where we 
abstract  water  for  treatment,  which  could  generate  problems  in  our  water  treatment  in  coastal  areas  by 
damaging  our  collection  networks.   Additionally,  increases  in  air  temperature  could  affect  demand  for 
water.  Climate change may also reduce water levels in the reservoirs that power hydroelectric plants in 
Brazil, which may cause energy shortages and increase electricity prices, which may adversely affect our 
costs and operations. 

We cannot predict all of the Effects of Extreme Weather Events, which makes it difficult to predict 
necessary  investments.   We  have  not  provisioned  any  funds  for  climate  change  events  as  current 
technology and scientific understandings of climate change make it difficult to predict potential expenses 
and liabilities.   

We  may  be  required  to  adopt  new  norms  to  improve  our  energy  use  efficiency  and  minimize  the 
release  of  greenhouse  gases  when  we  renew  the  environmental  licenses  for  the  systems  already  in 
operation or when we obtain environmental licenses for new enterprises.  

We  may  need  to  make  substantial  new  expenditures,  either  to  comply  with  new  environmental 
regulations  linked  to  climate  change  or  to  prevent  or  correct  the  physical  Effects  of  Extreme  Weather 
Events, any of which could have a material adverse effect on our results of operations. 

For more information, see “Item 4.B. Business Overview—Environmental Matters—Climate Change 

Regulations: Reduction of Greenhouse Gases (GHG).” 

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

Our  industry  is  affected  by  the  following  additional  risks  relating  to  the  provision  of  water  and 

sewage services: 

•                      The  state  and  federal  government  agencies  that  manage  water  resources  impose  substantial 
charges for the abstraction of water from bodies of water and the discharge of sewage.  We may 
not  be  able  to  pass  these  charges  on  to  our  customers.   See  “Item 4.B.  Business  Overview—
Government Regulation—Water Usage.” 

•                      The  increasing  degradation  of  watershed  areas  may  affect  the  quantity  and  quality  of  water 
available to meet demand from our customers.  See “Item 4.A. History and Development of the 
Company—Capital  Expenditure  Program”  and  “—Main  Projects  of  Our  Capital  Expenditure 
Program.” 

•                     In addition to the risks discussed under “—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,”  we 
may not be able to increase our tariffs on a timely basis, or at all, in order to pass on increases in 
inflation or operating expenses, including taxes, to our customers.  These constraints may 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.” 

  
   
  
 19 

 
•                      In  addition  to  the  risks  discussed  under  “—  New  laws  and  regulations  relating  to  climate 
change and changes in existing regulation, as well as the physical Effects of Extreme Weather 
Events, may result in increased liabilities and increased capital expenditures, which could have a 
material  adverse  effect  on  us,”  we  are  exposed  to  various  weather-related  risks,  since  our 
financial  performance  is  closely  linked  to  climate  patterns.   The  expected  increase  in  the 
frequency of extreme weather conditions in the future may adversely affect both the quality and 
quantity  of  waters  available  for  abstraction,  treatment,  and  supply.   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  services.   An  increase  in  heavy 
rainfall  could  impact  water  quality  and  the  regular  operation  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 Extreme Weather Events – 
Drought.”  

•                     We are dependent upon energy supplies to conduct our business.  Any 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 any significant increases in energy tariffs to our customers.  See “Item 4.B. Business 
Overview—Energy Consumption.” 

•                      We  depend  on  a  usage  rights  grant  from  ANA  and  DAEE  to  extract  water  in  the  Cantareira 
System.  In 2013, the Cantareira system accounted for 47.1% 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 73.2% of our gross operating revenues (excluding revenues 
relating  to  the  construction  of  concession  infrastructure)  for  the  year.   The  Cantareira  System 
usage  rights  grant  was  renewed  in  2004  and  will  expire  in  August  2014.   We  are  working  to 
renew this grant for a period of 30 years and to maintain the same withdrawal supply rights of 33 
m³/s  granted  in  2004.   Due  to  current  climate  conditions,  particularly  the  severe  drought,  the 
renewal process is temporarily suspended.  In addition, the current drought may provide a new 
context for definition of the rules related to the grants for the right to use water and we cannot 
guarantee that we will be able to renew the grant in accordance with the conditions we requested.  

Any of the above may have a material adverse effect on us.   

Droughts, the water consumption reduction program or other measures may result in a significant 

decrease in the volume of water billed and the revenues from services we provide, which may have a 
material adverse effect on our company. 

We  experience  decreases  in  our  water  supply  from  time  to  time  due  to  droughts.   Part  of  the 
southeastern region of Brazil, particularly the southern region of Minas Gerais State and the Piracicaba 
river basin (from which we extract the water used in the Cantareira System), and the northern area of the 
São Paulo metropolitan region experienced below average rainfall in 2012.  The drought worsened in late 
2013  and  early  2014,  with  rainfall  being  significantly  below  average, which resulted  in  lower reservoir 
water levels in the Cantareira System during the rainy season, from October 2013 to March 2014.  This 
was particularly the case for the Cantareira System, the largest system of the Metropolitan Region of São 
Paulo.  

In order to minimize the effects of this drought, in February 2014 we approved a water consumption 
reduction  incentive  program  based  on  a  bonus  system,  pursuant  to  which  customers  served  by  the 
Cantareira System who achieve a 20% reduction in water consumption are entitled to a 30% discount on 
their service bill.  Initially, this incentive program was scheduled to last seven months from February 1, 
2014 or until the water level in the reservoirs is normalized and sufficient to supply the customers in the 
São  Paulo  metropolitan  region  served by  the  Cantareira System.   However,  in April  2014  the  incentive 
program  was  extended  for  the  entire  São  Paulo  metropolitan  region  until  the  end  of  2014  or  until  the 
water  level  in  the  reservoirs  is  normalized.   As  a  result  of  the  drought  and  low  water  volume  in  the 
Cantareira System, the São Paulo State Department of Water and Energy (DAEE) and the National Water 

  
   
  
  
  
Agency  (ANA)  determined  that,  as  of  March  10,  2014,  we  must  temporarily  restrict  the  flow  of  water 
from the Cantareira System from 33 m³/s to 27.9 m³/s.  In order to continue to meet consumer demand 
with  a  restricted  water  supply,  we  are  increasing  our  use  of  other  water  systems.   This  may  lead  to  an 
increase  in  our  costs  to  serve  customers  in  the  São  Paulo  metropolitan  region.   If  the  situation  in  the 
reservoirs affected by the drought does not improve, we may be obligated to take more drastic measures.   

 20 

  
 
As a result of this drought and of the measure imposed by the DAEE and ANA, our volume of water 
and  sewage  billed  may  decrease  throughout  2014.   In  addition,  our  operating  costs  may  increase  as  a 
result  of  additional  capital  expenditures  required  to  mitigate  the  effects  of  this  drought  on  our  water 
production systems.  We cannot assure you that the consumption reduction incentive program will be the 
only mitigating measure we take to address the severe drought.  Although we expect our billing amount to 
decrease, due to volume decrease and bonus payments, we cannot estimate the impact of this program on 
our revenues.  In addition, we cannot assure you that any continuous drought in the future will not have 
any impact on our covenant clauses or any material and adverse effects on our water supply and thus our 
business and results of operations. 

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

effect on us. 

We are party to a number of legal proceedings involving significant monetary claims.  These legal 
proceedings  include,  among  others,  civil,  tax,  labor,  corporate  and  environmental  issues.   As  of 
December 31, 2013, the total value of all outstanding claims against us was R$38,604.6 million (net of 
R$323.4 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 our financial condition.  We have provisioned a 
total  aggregate  amount  of  R$1,180.4  million  (net  of  court  deposits)  as  of  December 31,  2013  to  cover 
probable  losses  related  to  legal  proceedings.   This  provision  does  not  cover  all  legal  proceedings 
involving  monetary  claims  filed  against  us  and  it  may  be  insufficient  to  cover  our  liabilities  related  to 
these  claims.   Any  unfavorable  judgment  in  relation  to  these  proceedings  may  have  a  material  adverse 
effect  on  us.   For  more  information,  see  “Item 8.A.  Financial  Information—Financial  Statements  and 
Other Financial Information—Legal Proceedings.” 

Risks Relating to Our Common Shares and ADSs 

We may not always be in a position to pay dividends or interest on shareholders’ equity and ADSs. 

Depending  on  our  future  results,  our  shareholders  may  not  receive  dividends  or  interest  on  own 
capital  if  we  do  not  generate  a  profit.   Despite  the  requirement  to  distribute  a  minimum  of  25%  of  our 
annual net income to shareholders, our future financial position may not permit us to distribute dividends 
or pay interest on own capital. 

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 from emerging markets such as Brazil 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  51.2%  of  the  aggregate  market  capitalization  of  the  BM&FBOVESPA  as  of 
December 31, 2013.  The top ten stocks in terms of trading volume accounted for approximately 41.3%, 
43.0% and 47.2% of all shares traded on the BM&FBOVESPA in 2013, 2012 and 2011, respectively.  

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

abroad and obtain Brazilian tax advantages. 

The  Brazilian  custodian  for  the  common  shares  underlying  our  ADSs  must  obtain  a  certificate  of 
registration  from  the  Central  Bank  in  order  to  be  entitled  to  remit  U.S. dollars  abroad  for  payments  of 
dividends and other distributions relating to our common shares or upon sales of our common shares.  If 
an ADR holder decides to exchange ADSs for the underlying common shares, the 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 sale 
of our common shares, or distributions relating to our common shares, unless he or she obtains his or her 
own  certificate  of  registration  or  registers  under  Resolution  No. 2,689,  dated  January 26,  2000,  of  the 
CMN,  which  entitles  registered  foreign  investors  to  buy  and  sell  on  a  Brazilian  stock  exchange.   If  the 
holder does not obtain a certificate of registration or register under Resolution No. 2,689, the holder will 
generally be subject to less favorable tax treatment on gains with respect to our common shares. 

21 

 
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.  The 
custodian’s  certificate  of  registration  or  any  foreign  capital  registration  obtained  by  a  holder  may  be 
affected by future legislative changes, and additional restrictions applicable to the holder, the disposition 
of the underlying common shares or the repatriation of the proceeds of disposition may 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 more difficulty in protecting his or her interests in the case of actions by our directors, officers or our 
controlling  shareholder  than  would  shareholders  of  a  corporation  incorporated  in  a  state  or  other 
jurisdiction of the United States.  In addition, under Brazilian law, none of our assets which are essential 
to our ability to render public services are subject to seizure or attachment.  Furthermore, the execution of 
a judgment against our controlling shareholder may be delayed, since the State may only be able to pay a 
judgment if it is provided for in its budget in a subsequent fiscal year.  None of the public property of our 
controlling shareholder is available for 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 
Novo Mercado rules, Law No. 6,404 of December 15, 1976, as amended (“Brazilian Corporate Law”) and 
Brazilian  capital  markets  regulations  will  be  resolved  by  arbitration  conducted  pursuant  to  the 
BM&FBOVESPA  Arbitration  Rules  in  the  Market  Arbitration  Chamber.   Any  disputes  among 
shareholders and ADR holders, and any disputes between us and our shareholders and 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.   

Holders of our ADSs do not have the same voting rights as our shareholders.  

Holders  of  our  ADSs  do  not  have  the  same  voting  rights  as  holders  of  our  shares.  Holders  of  our 
ADSs are entitled to the contractual rights set forth for their benefit under the deposit agreements. ADS 
holders  exercise  voting  rights  by  providing  instructions  to  the  depositary,  as  opposed  to  attending 
shareholders  meetings  or  voting  by  other  means  available  to  shareholders.  In  practice,  the  ability  of  a 

  
   
  
holder  of  ADSs  to  instruct  the  depositary  as  to  voting  will  depend  on  the  timing  and  procedures  for 
providing  instructions  to  the  depositary,  either  directly  or  through  the  holder’s  custodian  and  clearing 
system. The deposit agreement also provides that if the depositary does not receive any instructions from 
a  holder  of  ADRs,  the  ADR  holder  may  be  deemed  to  have  given  a  discretionary  proxy  to  a  person 
designated by our company and the underlying shares may be voted by such person.  However, we chose 
not  to  designate  any  person  to  exercise  these  deemed  proxy  rights  with  respect  to  the  annual  general 
meeting  held  to  approve  our  financial  statements  for  2013,  and  ADSs  for  which  no  specific  voting 
instructions were received by the Depositary were therefore not voted at that 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  with  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.  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—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 2012, according to the 14th edition of the Pinsent Masons Water Yearbook 2012-
2013).  We operate water and sewage systems in the State of São Paulo, which includes the city of São 
Paulo,  Brazil’s  largest  city.   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,  2013,  we  generated  net  revenue  of  R$11,315.6  million  and  net  income  of  R$1,923.6 
million.  Our total assets amounted to R$28,274.3 million and our total shareholders’ equity amounted to 
R$12,930.8 million as of December 31, 2013. 

As  of  December 31,  2013,  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.  At year-end 2013 we lacked formal agreements for 61 of the municipalities we serve, each 
of which we are in the process of actively renegotiating, including in the municipality of Santos.  From 
January 1, 2014 through 2034, 38 further concessions will expire, and we will seek to replace them with 
program agreements. In addition to the 363 municipalities we served, we also provided water service to 
the municipality of Mogi das Cruzes, pursuant to two partial water contracts under which we service only 
certain neighborhoods of that municipality. See “Presentation of Financial and Other Information—Other 
Information—Our Contracts and the Municipalities We Serve.” 

We also supply water on a wholesale basis to 6 municipalities in the São Paulo metropolitan region 
in  which  we  do  not  operate  water  distribution  systems  (together  covering  a  total  estimated  urban 
population of approximately 3.5 million).  Five of these municipalities also utilize our sewage treatment 
services.   For  the  year  ended  December 31,  2013,  the  São  Paulo  metropolitan  region  (including  the 
municipalities  to  which  we  provide  water  on  a  wholesale  basis)  accounted  for  73.2%  of  our  gross 
operating revenue (excluding revenues relating to the construction of concession infrastructure), while the 
Regional Systems accounted for 26.8%. 

As  of  December 31,  2013,  we  provided  water  services  through  7.9  million  water  connections  to 
approximately 24.6 million people, representing approximately 59% of the urban population of the State 
of São Paulo, and had a water coverage ratio of approximately 99% in respect of all regions.  As of that 
date, we provided sewage services through 6.3 million sewage connections to approximately 21.5 million 
people and had an effective sewage coverage ratio of 84%.  As of December 31, 2013, we operated using 
69,619 kilometers of water pipes and water transmission lines and 47,103 kilometers of sewer lines.

We  also  provide  water  and/or  sewage  services  to  4  other  municipalities  through  special  purpose 
companies.   In  addition,  we  provide  consulting  services  regarding  the  rational  use  of  water  and 
commercial  and  operational  management  in  Panama  and  Honduras  through  a  partnership  with  Latin 
Consult.  In  addition  we  set  up  two  new  activities  in  partnership  with  other  companies:   Aquapolo 
Ambiental S.A., a joint venture with a private sanitation services operator, which commenced operations 
in  the  second half of 2012  and  operates  the  largest  water  recycling  facility  in  the  southern hemisphere, 
with capacity to supply up to 1,000 liters per second to industries in the Capuava petrochemical cluster in 
the  São  Paulo  metropolitan  region;  and  Attend  Ambiental,  a  joint  venture  with  Estre  Ambiental  S.A., 
which  is  constructing  a  pre-treatment  plant  for  non-domestic  effluent  in  the  São  Paulo  metropolitan 
region that is expected to commence operations in the first half of 2014. 

The State of São Paulo, our controlling shareholder, is required by law to own at least 50% plus one 
of our common shares.  As of April 16, 2014, 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  State’s  overall  strategic  planning.   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  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  derive  from  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  24.6  million  people  and  supply  water  on  a  wholesale 
basis to an additional urban population of approximately 3.5 million people.  As of December 31, 2013, 
we  had  an  effective  water  coverage  ratio  of  approximately  99%  in  respect  of  all  regions  in  which  we 
operate.   We  also  provide  sewage  services  directly  to  approximately  21.5 million  people,  achieving  an 
effective sewage coverage ratio of 84% in respect of all regions in which we operate as of December 31, 
2013.  During the year ended December 31, 2013, our net operating revenues (including revenues relating 
to the construction of concession infrastructure) increased by 5.4% as compared to 2012.  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  skill  in  operating  in  adverse 
conditions, 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, which is located in 
the most developed and economically active region of Brazil, is the most populous state in Brazil, with an 
estimated total population of 44 million as of December 31, 2013.  The city of São Paulo had an estimated 
total  population of  11  million  as  of  the  same  date,  while  the  São Paulo  metropolitan region  had  a  total 
population  of  21  million.   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$1.3 trillion  in  2011, 
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  Base  of  Contracted  Business.   Between  January 1,  2007  and  December 31,  2013,  we 
executed 30-year agreements with 266 of the 363 municipalities we serve, including an agreement with 
the City of São Paulo in June 2010.  For the year ended December 31, 2013, income from these 30-year 
agreements  accounted  for  72.9%  of  our  gross  operating  revenues  (including  revenues  relating  to  the 
construction of concession infrastructure). 

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.   We  do  not  depend  on  a  limited  number  of 
sources  of  financing,  but  instead  have  access  to  various  funding  alternatives  in  the  Brazilian  and 
international markets to fund our working capital needs and our capital expenditure programs. 

 24 

 
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  certain  corporate  governance  standards  that  are  not 
otherwise  required  by  Brazilian  law,  which  provides  heightened  protection  to  our  shareholders  and 
enhances 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 employ the best 
available technology in the sanitation business to control the quality of the water we abstract, process and 
distribute.  All of our water quality control laboratories operate in accordance with the ABNT NBR ISO 
9001 standard, the highest international water quality standard.  In addition to our central laboratory, 12 
of  our  regional  laboratories  are  accredited  by  the  National  Institute  of  Metrology,  Standardization  and 
Industrial  Quality,  or  INMETRO,  and  comply  with  the  ABNT  NBR  ISO  IEC  17025  standard,  thereby 
assuring the quality and accuracy of our test results.  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. 

Our Strategy  

Our mission is to provide water and sewage services, contributing to improvements in quality of life 
and  the  environment.   To  this  end,  our  strategic  objectives  are  based  upon  the  guiding  principles  of 
growth, quality, universalization of sanitation services, social, economic and environmental sustainability, 
human  capital  as  a  competitive  strength  and  innovation,  while  focusing  on  reaching  excellence  in 
customer  service.   Our  strategic  objectives  also  focus  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: 

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 strengthen our 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  loss.  We seek  to reduce  both physical  water  loss, 
which  results  mainly  from  leakage;  non-physical  water  loss,  which  results  primarily  from  inaccurate 
water  meters  installed  at  customers’  premises  and  at  our water  treatment  facilities;  and  clandestine  and 
illegal  water  use.   In  order  to  achieve  more  consistent  long-term  results,  we  have  developed  a 
comprehensive 12 year program to reduce our water loss rate.  The first four years of the program from 
2009 to 2012 were funded by BNDES.  From 2013 to 2017 the program will be funded by a loan granted 
by the government of Japan through the Japan International Cooperation Agency, or JICA.  The program 
focuses  on  renewing  our  water  distribution  infrastructure  and  improving  the  pressure  control  and  the 
maintenance  and  control  services  as  a  means  of  reducing  physical  water  loss.   We  are  also  seeking  to 
reduce physical water loss by creating smaller water supply districts through the construction of district 
metering areas, which reduce system pressure and pipe bursts, and allow leaks to be detected and repaired 

  
   
  
more efficiently.  The program also seeks to reduce non-physical water loss by upgrading and replacing 
inaccurate  water  meters  and  through  inspections  of  non-authorized  water  consumption  in  water  service 
connections. 

 25 

 
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 1.17 million water connections between 
2014 and 2020.  We also intend to increase our sewage coverage ratio to 95% by 2020 by adding 1.65 
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 different types of clients, which we 
believe will help us increase our customer base.  We also seek to improve our customer support strategies 
by modernizing our telephone and internet-based customer support and to continuously measure the level 
of satisfaction of our clients. 

Maintain and continue to expand our existing service areas.  We intend to maintain and expand our 
operating  base  by  executing  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 concession agreements as they expire.  In June 2010, 
we entered into a 30-year agreement with the State and city of São Paulo for the provision of water and 
sewage  services  in  the  city  of  São  Paulo,  which  in  the  year  ended  December 31,  2013  accounted  for 
51.8%  of  our  gross  operating  revenues  (excluding  revenues  relating  to  the  construction  of  concession 
infrastructure).  Between January 1, 2007 and December 31, 2013, we entered into agreements with 265 
municipalities (including our services agreement with the city of São Paulo), of which seven were entered 
into  in  2013.   These  265  municipalities  accounted  for  72.9%  of  our  total  revenues  for  the  year  ended 
December 31, 2013 and 64.6% of our intangible assets as of the same date.  As of December 31, 2013, 61 
of our concessions had expired and are currently being renegotiated.  These 61 municipalities accounted 
for 16.1% of our total revenues for the year ended December 31, 2013 and 25.1% of our intangible assets 
as of the same date.  From January 1, 2014 through 2034, 38 concession agreements, accounting for 9.0% 
of our revenues for the year ended December 31, 2013 and 8.0% of our intangible assets as of the same 
date, will expire. 

Our investment plan will include the investment of R$12.8 billion between 2014 and 2018, 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, in order to 
encourage  these  customers  to  continue  using  our  services.  We  also  regularly  explore  the  possibility  of 
executing agreements for the provision of water and sewage services in municipalities in 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,  which  together  represent  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  an  effective  sewage coverage  ratio  of 84%  as  of 
December 31, 2013 and plan to increase this ratio to 95% by 2020 by adding over 1.65 million sewage 
connections.  In addition, there are municipalities in the State of São Paulo representing a total 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 
these additional municipalities in the State of São Paulo, as well as to other Brazilian states 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 to these clients. 

Seek selective opportunities to expand our business.  Our activities comprise water supply, sanitary 
sewage services, urban rainwater management and drainage services, urban cleaning services, solid waste 
management  services.   We  are  looking  into  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.  Since  2008,  we  have  expanded  into 
activities  that  complement  water  and  sewage  services  in  which  we  may  leverage  our  know-how,  size, 
scale and profitability. For example: 

  
   
  
•                      We  are  planning  to  install  small  hydroelectric  power  plants  in  our  water  treatment  plants  in 
Guaraú and Cascata in conjunction with the Servitec/Tecniplan consortium.  We expect to start 
construction of the first two plants, with capacities of 4 and 2 MW, in the second half of 2014. 

26 

 
•                     We worked with the basic sanitation company of the state of Alagoas to transfer technology for 
the reduction of water loss in the city of Maceió. Under this type of contract, we are remunerated 
based on our success rate, or more specifically, we profit based on the reduction of water loss 
achieved in city of Maceió.  

•                     In partnership with the consultancy firm Latin Consult, we are providing consulting services to 
the Instituto de Acueductos y Alcantarillados Nacionales, the company responsible for water and 
sewage services in the central provinces of Panama, in the field of sustainable water use and to 
implement a new model for commercial, financial and operational planning and management. 

•                      Also  in  partnership  with  Latin  Consult,  we  are  providing  consulting  services  to  seven 
municipalities in Honduras to implement a new commercial and operational management model. 

•                      We  have  set  up  Attend  Ambiental,  a  joint  venture  with  Estre  Ambiental  S.A.,  which  is 
constructing  a  pre-treatment  and  processing  plant  for  non-domestic  effluent  in  the  São  Paulo 
metropolitan region that is expected to commence operations in the first half of 2014.  

•                     We are looking into the production and distribution of bio methane from gas generated in our 

sewage treatment processes. 

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 our employees, setting competitive benefit packages and 
creating a healthy and collaborative work environment. 

Streamline internal processes.  We are implementing plans to increase our speed and productivity in 
responding to regulatory changes; strengthen and streamline our financial, commercial and administrative 
structure; and increase the efficiency of our operations; while also reducing costs.  To this end, in 2012 
we began implementing an enterprise resourcing planning (ERP) system to replace our commercial and 
management  information  systems.  We  contracted  through  a  bidding  process  the  Águas  Claras 
Consortium,  which  consists  of  companies  Accenture  and  Engineering  and  which  will  provide  us  with 
SAP’s ERP system and the Net@suite system. We estimate that the ERP will be implemented in 2014, 
and the Net@suite in 2015.  

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 and is bordered by 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 44 million as of December 31, 2013.  The city of São Paulo, capital of the State of São 
Paulo, had an estimated total population of 11 million, with a total population of 21 million inhabitants in 
the  São  Paulo  metropolitan  region,  as  of  December 31,  2013.   The  São  Paulo  metropolitan  region 
encompasses 39 municipalities and is the largest metropolitan region in the Americas and the sixth largest 
metropolitan  region  in  the  world,  according  to  the  United  Nations’  World  Urbanization  Prospects, 
2011 Revision,  with  approximately  47%  of  the  total  population  of  the  State  of  São  Paulo  as  of 
December 31, 2013. 

  
   
  
According to the IBGE, the GDP of the State of São Paulo was approximately R$1.3 trillion in 2011, 
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 leading 
export  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 
provision  of  water  and  sewage  services  to  Companhia  Cantareira  de  Água  e  Esgotos.   In  1893,  the 
government of the Province of São Paulo assumed responsibility for the provision of water and sewage 
services  from  Companhia  Cantareira  de  Água  e  Esgotos  and  formed  the  Office  of  Water  and  Sewers 
(Repartição de Água e Esgotos), a government 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  directly  by  the 
municipalities, 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 carry out the administration of public services where the government deems 
that a decentralized administrative and financial structure would be advantageous. 

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  various  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 State government created the Superintendence of Water and Sewers of the city of 
São Paulo (Superintendência de Água e Esgoto da Capital), or the SAEC, to distribute water and collect 
sewage in the city of São Paulo.  All assets relating to water services previously owned by the Department 
of Water and Sewers 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  relating  to  sewage  services  previously  owned  by  the  Department  of  Water  and  Sewers  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  our  company.   The  State  has  always  been  our  controlling  shareholder,  as  required  by  State  Law 
No. 119.  We have therefore been integrated into the State governmental structure and our strategies have 
been  formulated  in  conjunction  with  the  strategies  of  the  State  Department  of  Water  Resources  and 
Sanitation.  Additionally, a majority of the members of our board of directors and our  management  are 
appointed by the State Government. 

Our capital expenditure budget is subject to approval by 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.  We are 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 and budgetary activities and our operating assets. 

28 

  
   
  
 
We  provide  water  and  sewage  services  directly  to  a  large  number  of  residential,  commercial  and 
industrial private consumers, as well as to a variety of public entities, in 363 of the 645 municipalities in 
the  State,  including  in  the  city  of  São  Paulo.   We  also  supply  water  on  a  wholesale  basis  to  6 
municipalities  in  the  São  Paulo  metropolitan  region  in  which  we  do  not  operate  water  distribution 
systems, and five of these municipalities also utilize our sewage treatment services.  Currently, we are the 
fifth largest water and sewage service company in the world in terms of number of clients, according to 
the 14th edition of the Pinsent Masons Water Yearbook (2012-2013).  

In 1994, we were registered with the CVM as a publicly-held company and are therefore subject to 
the  CVM’s  rules,  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.   In  the  same  year,  we  registered  our 
common shares with the Securities and Exchange Commission, or SEC, and started trading our shares in 
the  form  of  American  Depositary  Receipts  –  level  III  (“ADRs”)  on  the  New  York  Stock  Exchange,  or 
NYSE. 

In 2004, the State of São Paulo carried out a secondary offer of common shares of our company in 
the Brazilian and international markets.  On December 1, 2007, we became part of the BM&FBOVESPA 
ISE, which reflects our high degree of commitment to sustainable environmental and social practices. 

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

Corporate Organization 

We currently have six management divisions, each of which is supervised by one of our executive 

officers.

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 with respect to 
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 loss.  

Our  capital  expenditures  from  2011  through  2013  totaled  R$7.7  billion.  We  have  budgeted 
investments in the total amount of R$12.8 billion from 2014 through 2018.  We invested R$2.7 billion, 
R$2.5 billion and R$2.4 billion in 2013, 2012 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  2014  through  2018  will  continue  to  focus  on  achieving  our 
targets by making regular investments to maintain and expand our infrastructure and to reduce water loss 
in the 363 municipalities we served as of December 31, 2013.  

Main Projects of Our Capital Expenditure Program 

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

Metropolitan Water Program 

Demand  for  our  water  services  has  grown  steadily  over  the  years  in  the  São  Paulo  metropolitan 
region and has at times exceeded the capacity of our water systems.  As a result, prior to September 1998, 
a portion of our customers in this region received water only on alternate days of the week.  We refer to 
this as “water rotation.”  In order to remedy this situation, we implemented the (Programa Metropolitano 
de  Água)  to  improve  regular  water  supply  to  the  entire  São  Paulo  metropolitan  region.   This  program 
terminated  in  2000  and  the  water  rotation  measure  was  eliminated,  but  we  have  maintained  our 
investment plans for the region.

The second phase of the Metropolitan Water Program, projected to result in an increase of 13.2 m³/s 
in  water  production  capacity,  started  in  2006  and  is  expected  to  run  through  2014.   Within  this  phase, 
there has been an increase of 5.5 m³/s in water production capacity (of which 5 m³/s through the Alto do 
Tietê Public Private Partnership (PPP) concluded in 2011), and there is a plan to increase another 1 m³/s 
in 2014.  Total investments made from 2006 to December 31, 2013, amounted to R$1.6 billion, including 
our own funds and financing from Caixa Econômica Federal and Banco Nacional de Desenvolvimento 
Econômico  e  Social  (“BNDES”),  as  well  as  the  investments  from  the  Alto  Tietê  Public  Private 
Partnership.  In 2013, we invested approximately R$128 million in this program. 

In 2013, the goals of the Program were revised, and we initiated the Program’s third phase.  We plan 
to  increase  water  production  capacity  by  9.5  m³/s  in  the  São  Paulo  Metropolitan  Region  by  2018, 
including the new São Lourenço System.  This new system alone will increase water production capacity 
by 4.7 m³/s.  The projected investments in the Program’s third phase may reach R$4.4 billion, including 
the  investments  in  the  São  Lourenço  PPP.   For  information  on  Public  Private  Partnerships,  see  “—
Business Overview—Public Private Partnerships.” 

Alto Tietê Public Private Partnership 

In  June 2008  we  formed  the  Alto  Tietê  PPP  with  a  special  purpose  company  known  as  Cab  Spat, 
whose main shareholders are Cab Ambiental and Galvão Engenharia S.A.  The Alto Tietê PPP is part of 
the second phase of the Metropolitan Water Program and aims to improve the reliability, flexibility and 
availability  of the  integrated water  system  that  serves  the São Paulo  metropolitan  region.   Through  this 
PPP,  Cab  Spat  carried  out  certain  infrastructure  works,  which  were  completed  in  December 2011,  and 
expanded the Alto Tietê System nominal capacity from 10 cubic meters per second to 15 cubic meters per 
second.   

Cab  Spat  has  also  undertaken  to  perform  maintenance  on  the  Alto  Tietê  System’s  dams  on  an 
ongoing  basis.   This  maintenance  work  consists  of  civil  engineering,  electromechanical  and operational 
services, as well as sludge treatment, water adduction and water supply. 

The total estimated cost for this project, including the investments and the System’s maintenance, is 
R$1.0 billion.   We  intend  to  complete  payment  for  these  by  2024.  For  information  on  Public  Private 
Partnerships, see “—Business Overview—Public Private Partnerships.” 

São Lourenço 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, which will expand our production capacity by 4.7 m3/s and should be able to 
benefit a population of almost 1.5 million people.  The PPP contract was executed in August 2013 and the 
works will begin in the first semester of 2014. Sistema Produtor São Lourenço S.A. is a Special Purpose 
Company (SPC) consisting of the construction companies Camargo Correa and Andrade Gutierrez. The 
new system is expected to begin operating in 2018. For information on Public Private Partnerships, see 
“Business Overview—Public Private Partnerships.” 

The  contract  is  in  the  amount  of  approximately  R$6  billion  (including  the  investment  in  the 
construction of R$2.2 billion and the system’s operation and maintenance) and it has a 25-year term, four 
years of which will be dedicated to the construction, while the other 21 years will be dedicated to service 
delivery.  These  services  include  the  operation  and  maintenance  of  the  sludge  treatment  system  of  the 
water treatment station and disposal of the waste thus generated; electromechanic and civil maintenance 
of the untreated water pumping stations, of the water treatment station and the untreated water pipeline; 
preservation and cleaning, surveillance and property security.      

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 carried out the first 
phase of the program between 1992 and 1998. 

 31 

 
In  the  first  phase  of  the  Tietê  Project,  we  completed  the  construction  of  three  additional  sewage 
treatment  facilities  in  June 1998.   This  involved  total  investment  of  US$1.1 billion,  of  which  US$450 
million was financed by the Inter-American Development Bank, or IADB, approximately US$100 million 
by Caixa Econômica Federal, and approximately US$550 million by us. 

The second phase of the project, which was carried out from 2000 through 2008, involved installing 
290,000 sewage  connections  and  more  than  1,500  kilometers  of  sewage  collection  networks,  branch 
collectors and interceptors.  Total investments in this phase amounted to approximately US$500 million, 
of  which  US$200  million  was  financed  by  the  IADB,  R$60  million  by  BNDES  directly,  and  R$180 
million by BNDES through another financial institution. 

The  main  objective  of  the  second  phase  was  to  continue  expanding  and  optimizing  the  sewage 
system in the São Paulo metropolitan region, focusing primarily on improvements to expand the delivery 
of raw sewage to the sewage treatment facilities that were built in the first phase.  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 to the five sewage treatment plants in our integrated system for treatment.  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 sewage collected in 
the  São  Paulo  metropolitan  region.   As  a  result,  the  sewage  collection  system  covered  a  total  of 
15.8 million  people  (5.1 million  more  than  the  number  of  people  served  when  the  Tietê  Project  was 
initiated),  and  the  sewage  treatment  system  covered  11.1 million  people  (8.5 million  more  than  the 
number  of  people  served  when  the  Tietê  Project  was  initiated).   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 16 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, initiated in 2010, aims to remediate the water quality in the Tietê 
river  basin  by  expanding  collection  levels  to  87.0% and  sewage  treatment  levels  to  84.0%  in  the  São 
Paulo metropolitan region.  The total estimated cost of the third phase is approximately US$2 billion, of 
which  US$600  million  will  be  financed  by  a  loan  from  the  IADB  entered  into  in  September  2010  and 
approximately  R$  1.35  billion  by  a  loan  from  BNDES  entered  into  in  February  2013.   The  third  phase 
consists principally of the following items: 

•                      improvements  to  the  effluent  collection  system  through  collection  networks  and  home 

connections; 

•                     removal and transport of effluent for treatment through branch collectors and interceptors; and 

•                     the construction of new sewage treatment plants in the São Paulo metropolitan region.   

Approximately 76% of the work for the third phase is under construction, and a further 7% is in the 
process  of  public  tender.   Following  completion  of  the  third  phase  of  the  Tietê  Project,  the  sewage 
collection system will serve an additional 1.5 million people and the sewage treatment system will serve 
an  additional  3  million  people.   We  have  invested  R$1.1  billion  in  the  third  phase,  R$358  million  of 
which during 2013. 

Continuing our efforts to eliminate the disposal of in natura sewage, in the bodies of water of the São 
Paulo  Metropolitan  Region,  by  the  areas  we  serve,  we  are  currently  structuring  the  fourth  phase  of  the 
Tietê Project, which is expected to begin in 2014 with investments estimated at US$2 billion. We have 
been seeking financing sources from the Federal Government and international institutions, similarly to 
what happened in the earlier phases of the program.

Corporate Program for Reduction of Water Loss 

The  objective  of  the  Corporate  Program  for  Reduction  of  Water  Loss  (Programa  Corporativo  de 
Redução  de  Perdas  de  Água)  is  to  reduce  water  loss  efficiently  by  integrating  and  expanding  existing 
initiatives in our business units.  This program has a 12-year term that began in 2009.  We have invested 
R$1.5  billion  in  this  project  so  far,  including  R$424  million  invested  in  2013,  and  anticipate  total 
investments of approximately R$5.9 billion throughout the term of the program.  Funding for the program 
will come from our own resources as well as from credit facilities provided by JICA, Caixa Econômica 
Federal  and  BNDES.   The  program  aims  to  reduce  the  incidence  of  water  loss  from  436 liters  per 
connection per day in December 2008 to 280 liters per connection per day in 2020, which is equivalent to 
reducing  the  Non-Revenue  Water  Index  from  27.6% in  December 2008  to  18%  in  2020.   This  is 
equivalent  to  reducing  the  water  loss  index  (based  on  metered  consumption)  from  34.1%  in 
December 2008  to  25.7%  in  2020.   Since  the  beginning  of  the  program,  we  reduced  the  Non-Revenue 
Water Index by 3.2%, reaching 24.4% in December 2013.  Regarding the utilization of water sources, the 
drop in real water loss (water physically lost, which corresponds to about 65% of the Water Loss Index) 
dropped from 22.2% in December 2008 to 20.3% in December 2013.   

Mananciais/New Life Program  

The Mananciais/New Life Program (Programa Vida Nova) consists of various projects that focus on 
the preservation and improvement of water reserves in the São Paulo metropolitan region, especially in 
the  Guarapiranga  and  Billings  reservoirs.   The  resources  will  be  mostly  invested  in  the  creation  of 
infrastructure  to  collect  sewage  and  transport  it  to  treatment  plants  in  order  to  reduce  the  discharge  of 
effluent  into  water  sources.   The  program  also  includes  the  protection  of  green  spaces  and  the 
urbanization of favelas (shantytowns) and is expected to directly benefit 58,000 families by 2015.  

The  State  government,  local  authorities  and  the  federal  government  are  expected  to  invest 
approximately R$1.6 billion in this program by the end of 2015.  To implement this program, we estimate 
we will invest R$335 million.  As of December 31, 2013, the total amount of cumulative investments in 
this program reached R$117 million, R$48.4 million of which was invested in 2013.     

Clean Stream Program  

The  Clean  Stream  Program  (Programa  Córrego  Limpo),  a  partnership  between  the  State,  acting 
through our company, and the municipality of São Paulo, aims to decontaminate urban streams in the city 
of São Paulo by eliminating the discharge of sewage into streams and rainwater runoff routes, cleaning 
streams and banks, and removing and relocating of properties located on the banks of streams.  

Total investments made in this program amounted to R$730.3 million as of December 31, 2013, of 
which  we  had  invested  R$130  million.   146  urban  streams  have  been  decontaminated  since  2007, 
benefiting approximately 2 million people. In 2013, 30 urban streams have been decontaminated and we 
had invested R$20 million in this Program. Part of the investment related to the Tietê Program benefit the 
Clean Stream Program.  

In 2013, we began the fourth phase of the Clean Stream Program, and we expect to completely or 
partially  decontaminate  more  than  20  large  streams  by  the  end  of  2014,  with  investments  of 
approximately R$100 million.  

Regional Systems Investment Programs 

We currently have a number of projects in progress and planned for our Regional Systems.  These 
relate  to  the  abstraction  of  water  as  well  as  to  the  collection,  removal  and  disposal  of  sewage.   We 
invested  approximately  R$1.1  billion  per  year  in  these  projects  in  2013,  2012  and  2011,  and  we  have 
budgeted for additional capital expenditures of approximately R$3.7 billion from 2014 through 2018. 

  
   
  
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%,  and  treating  100%  of  the  collected  sewage,  thereby  improving  bathing 
water quality at 82 beaches in the region by the end of the decade.  This project is being carried out in two 
phases, the first of which has started and the second of which is in the planning phase.  The first phase is 
expected  to  be  completed  by  2016,  aiming  at  increasing  the  sewage  collection  rate  to  88%.   The  funds 
will  come  from  our  own  resources  as  well  as  from  loan  agreements  entered  with  JICA  and  from  the 
Government  Severance  Indemnity  Fund for  Employees (Fundo  de Garantia por  Tempo de  Serviço),  or 
FGTS. 

33 

 
As  of  December 31,  2013,  we  had  invested  approximately  R$1.9  billion  in  this  program,  of  which 
R$75.5  million was invested during 2013.  As a result, sewage collection increased from 53% to 72%, 
and the treatment of collected sewage rose from 96% to 100%. 

After  completing  the  construction  of  sewage  treatment  plants  and  installation  of  networks,  we  are 
prioritizing the connection of customers to the sewage collection system. As of December 31, 2013, we 
had completed 84 thousand connections.  

Additionally,  complimentary  works  of  the  first  phase  shall  be  executed  between  2013  and  2016, 
including  an  addition  of  33  thousand  sewage  connections,  which  refer  to  connections  that  were  not 
executed in the first phase.  We expect to evaluate the service of sewage collection rate by 88% by the 
end of this phase. These works have an approximated investment value of R$400 million. 

Still in the first stage, we will work until 2017 on the system of oceanic sewage disposal in the city of 
Praia Grande, which is an important city in the Baixada Santista region, on the coast of São Paulo state. 
This will involve investments of approximately R$300 million. 

The second phase is in planning for the period between 2015 and 2020. We estimate investments in 
the  amount  of R$1 billion,  in  order  to  enlarge  and  implement  sewage  collection  and  treatment  systems 
and  complete  50  thousand  new  connections.  This  phase  of  the  Clean  Wave  Program  aims  at 
universalizing sewage services in the Metropolitan Region of Baixada Santista.  

Northern Coast Clean Wave Program  

The Northern Coast Clean Wave Program (Programa Onda Limpa Litoral Norte) aims at expanding 
the  collection  and  treatment  of  sewage  on  the  northern  coast  of  the  State  of  São  Paulo,  intending  to 
benefit 600 thousand people, including the local population as well as tourists that visit the region each 
year.  The program aims to increase the sewage collection rate in the region from 36.0% in 2008 to 85.0% 
in  2016,  thereby  improving  the  health  and  well-being  of  the  population  and  stimulating  economic 
development through an increase in tourism.  As of 2013, the sewage collection rate was 56%. 

Within this program, in 2013, we implemented collection networks, sewage connections and disposal 

systems, and built two Sewage Treatment Stations on beaches on the northern coast of São Paulo state.  

The funds in the amount of RS510 million that are necessary to conclude this program until 2016 will 
come  from  our  own  resources,  as  well  as  from  loan  agreements  entered  with  BNDES  and  Caixa 
Econômica Federal.  As of December 31, 2013, we had invested R$144 million in this program, of which 
R$18 million was invested during 2013.   

Coastal Water Program  

The  Coastal  Water  Program  (Programa  Água  no  Litoral)  combines  various  long-term  activities  to 
expand water production capacity in the Baixada Santista metropolitan region and the southern coast of 
the State of São Paulo.  The program aims to benefit approximately three million people, including both 
the  local  population  and  tourists.   It  aims  to  increase  the  level  of  reliability  of  the  local  systems, 
eliminating  existing  and  potential  deficiencies  and  irregularities  in  the  water  supply.  Through  this 
program we aim to increase the availability of treated water and improve the quality of water available to 
the population.  The fund will come from our own funds and financing from Caixa Econômica Federal. 

During  the  first  phase  of  this  program,  we  have  focused  mainly  on  increasing  water  production  in 
order to satisfy demand and improve water quality in the Baixada Santista metropolitan region.  In order 
to  reach  this  goal,  we  built  two  water  treatment  stations,  which  started  operations  in  2013: 
Mambu/Branco, with water treatment capacity of 1.6 m³/s, and Jurubatuba, with water treatment capacity 
of 2 m³/s.  

34 

  
   
  
 
As of December 31, 2013, we had invested R$858 million in this program, of which R$100 million 

was invested during 2013. The total investment estimated in this phase is R$1.1 billion. 

The  second  phase  of  the  program  is  in  planning,  with  the  goal  of  increasing  even  further  the 
availability of treated water for the local population and tourists and improving the quality of the water 
available to the population in the Baixada Santista metropolitan region in the coming years.

In December 2011, we launched the Nossa Guarapiranga project, the main objective of which is to 
remediate  the  water  quality  in  the  Guarapiranga  basin,  which  is  a  water  source  for  the  São  Paulo 
metropolitan  region.   The  basin  serves  one million  people  directly  in  the  areas  near  Guarapiranga,  and 
indirectly  serves  a  further  two million  people  who  consume  the  water  from  the  basin.   We  installed 
11 drains  to  collect  residue  from  rivers  in  the  Guarapiranga  basin,  and  since  July  2012,  we  have 
developed diagnosis and control services for the withdrawal of water plants that obstruct water extraction 
and deposit garbage at the bottom of the basin’s dam. The total amount invested from our own funds was 
R$12.2 million as of March 2014.  These actions will continue through 2014-2015 during which another 
R$4.3 million will be invested.   

Pró-Conexão  

In December 2011, Municipal Legislative Assembly of the city of São Paulo approved a project to 
subsidize connections to the sewage system for low-income families. Initially intended to last 8 years, the 
project involves capital expenditures of up to R$349.5 million of which 80% will be provided by the State 
government  and  20%  by  us.   In  this  period  we  expect  that  this  program  will  create  192  thousand  new 
connections benefiting approximately 800 thousand people.   

By  December  2013  we  completed  approximately  15  thousand  connections.  We  believe  that  this 
program will increase the efficiency of our sewage collection programs and help improve water quality in 
the region’s rivers and basins, as well as improving quality of life for low-income families.  

Water is Life  

The  Water  is  Life  program,  established  in  November 2011,  aims  to  provide  water  and  sewage 
services  to low-income  and  isolated  communities  in  the  regions  of  Alto  Paranapanema  and  Vale  do 
Ribeira.  In  the  first  phase  of  the  program,  we  expect  to  cover  81  communities  of  30  municipalities, 
benefiting approximately 15 thousand people. In this project we are responsible for supplying water, and 
the  municipalities,  with  financing  from  the  state  government,  are  responsible  for  installing  Individual 
Sanitary  Units  (Unidades  Sanitárias  Individuais),  which  is  a  technology  designed  for  low-income  and 
isolated communities.  Regarding the supply of water, we invested approximately R$6.5 million in well 
drilling and infrastructure projects (reservoirs, equipment, networks and pipelines).  We expect to invest 
approximately R$15 million by 2015.  

In 2013, we executed almost 64 kilometers of networks and pipelines to serve the program. A large 
part  of  these  works  were  executed  by  our  own  personnel,  which  considerably  reduced  the  need  for 
investment.  We  also  started  operating  20  new  wells  and  have  studies  and  projects  for  18  others.  We 
estimate  that  by  the  end  of  the  program  we  will  reach 220 kilometers  of network  and  pipelines  and  45 
wells.  

An amount of approximately R$6 million was estimated for sewage infrastructure construction, to be 
financed  by  the  State  Government.  This  amount  is  negotiated  between  the  municipalities  and  the  State 
Government, and we only indicate the technical solution that is most adequate for each region.

B.      Business Overview 

Our Operations 

As of December 31, 2013, we provided water and sewage services to 363 municipalities in the State 
of  São  Paulo  under  concession  agreements,  program  agreements,  other  forms  of  legal  arrangements  or 
without  formal  agreements.   We  also  supply  treated  water  on  a  wholesale  basis  to  six  municipalities 
located  in  the  São  Paulo  metropolitan  region.   Article 2  of  our  bylaws  permits  us  to  carry  out  the 
following activities:  provision of water supply and sewage services, urban rain water  management  and 
drainage services, urban cleaning services and solid waste 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. 

Following 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 concession agreements 
that have expired, we are currently renegotiating or will negotiate new agreements that follow the terms 
and  conditions  of  the  Basic  Sanitation  Law,  known  as  “program  agreements”;  and  (ii) for  concession 
agreements  that  have  not  expired,  we  will  continue  to  operate  under  the  terms  and  conditions  of  the 
existing  concession  agreements,  except  in  circumstances  where  the  Basic  Sanitation  Law  applies  even 
though the concession agreement is still in force.  For further information on this topic, see “Government 
Regulation—Public Consortia and Cooperation Agreement Law for Joint Management.” 

As  of  December 31,  2013,  61  of  our  agreements  or  concessions  were  still  in  the  process  of  being 
regularized  through  formal  agreements.   See  “3.D.  Risk  Factors—Risks Relating  to  Our  Business—We 
currently  lack  formal  agreements  or  concessions  with  61  of  the  municipalities  to  which  we  provide 
service, and 38 of our existing concession agreements will expire between 2014 and 2034.  We may face 
difficulties in continuing to provide water and sewage services in return for payment in these and other 
municipalities, and we cannot assure you that they will continue to purchase services from us on the same 
terms or at all.”  

Regulation of 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. 

As  of  December 31,  2013,  we  provided  water  and  sewage  services  to  363  municipalities.   The 
majority  of  these  concessions  have  30-year  terms.   Due  to  court  orders,  we  temporarily  suspended  our 
services  in  five  other  municipalities  (Cajobi,  Iperó,  Álvares  Florence,  Macatuba  and  Embaúba)  that 
accounted for less than 0.1% of our gross operating revenues and our intangible assets as of December 31, 
2013.   For  more  information,  see  “Item 8.A.  Financial  Information—Financial  Statements  and  Other 
Financial 
Information—Legal  Proceedings—Concession-Related  Legal  Proceedings.”   Between 
January 1, 2007 and December 31, 2013, we entered into agreements with 265 municipalities (including 
our services agreement with the city of São Paulo) in accordance with the Basic Sanitation Law, of which 
seven  were  entered  into  in  2013.   As  of  December 31,  2013,  these  265  municipalities  accounted  for 
72.9%  of  our  gross  operating  revenues  (including  revenues  relating  to  the  construction  of  concession 
infrastructure).   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 ARSESP.  As of December 31, 2013, 61 of our agreements or concessions had 
expired  but  we  continued  to  provide  water  and  sewage  services  to  these  61  municipalities  and  were  in 
negotiations  with  these  municipalities  to  execute  program  agreements  to  substitute  the  expired 
concessions.  From January 1, 2014 through 2034, 38 concessions will expire.  

36 

 
Following  the  increase  in  the  demand  for  regulatory  work,  we  created  a  regulatory  affairs 
department, which focuses on regulatory matters and has centralized communication with the regulatory 
agencies,  driving  business  to  the  new  regulatory  regime  and  proposing  matters  in  which  we  have  an 
interest to 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 Officer and  Investor Relations Officer, our Metropolitan Officer 
and our Regional Systems 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 from the date of 
acquisition of the concession, assuming a discount of at least 12%.  For reference purposes, ARSESP has 
set the discount rate for concession contracts at 8.06% since 2011. 

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

•                  we assume all responsibility for providing water and sewage services in the municipality; 

•                  according to the municipal laws authorizing the concession, we are permitted to collect tariffs for 
our  services  and  tariff  readjustments  follow  the  guidelines  established  by  the  Basic  Sanitation 
Law and ARSESP; 

•                  as a general rule, to date, we are exempt from municipal taxes, and no royalties are payable to 

the municipality with respect to the concession; 

•                  we are granted rights of way on municipal property for the installation of water pipes and water 

transmission lines, and sewage lines; and 

•                  upon  termination  of  the  concession,  for  any  reason,  we  are  required  to  return  the  assets  that 
comprise 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 relating to the concession. 

        These assets have been considered to be intangible assets since January 2008.  See Note 3.8 to our 
financial  statements.   Under  concession  agreements  executed  prior  to  1998,  the  reimbursement  for  the 
assets may be through payment of either: 

o    the book value of the assets; or 

o    the market value of the assets as determined by a third-party appraiser in accordance with 

the terms of the specific agreement. 

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 to 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. 

37 

 
Since 1998, our contracts with municipalities 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  greater  rights  and 
obligations to municipalities who are responsible for sanitation services 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—Public Consortia and Cooperation Agreement Law for Joint Management.” 

Our new agreement model follows the provisions of the Basic Sanitation Law.  Its main contractual 
provisions include the joint execution of planning, supervision and regulation of services, the appointment 
of a regulatory authority for the services, and periodic disclosure of financial statements. 

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, the preexisting assets will be returned to the grantor of the concession. 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 terminated our concession without our consent after asserting that we did not provide adequate 
water  and  sewage  services.   In  2011, we  and  the  municipality  of  Diadema  agreed  to  develop  shared 
infrastructure for water and sewage services through a mixed capital company to be called Companhia de 
Agua e Esgoto de Diadema, or CAED.  According to the agreement, the amount owed to us by Diadema 
would be repaid through the issuance of shares in CAED.  Studies regarding the establishment of CAED 
have been discontinued, and on March 18, 2014, we executed a contract to resume direct supply of water 
and  sewage  services  to  the  municipality  of  Diadema.   Concurrently,  we  entered  an  agreement  with 
Diadema  to  resolve  water  supply-related  debt  and  indemnities.   Guarantees  are  in  place  if  the 
municipality of Diadema breaches its agreement with us.   

The receivables owed to us by Mauá and Diadema total R$85.9 million and R$60.3 million, and have 
not been recognized in our financial statements due to the uncertainty of our ability to collect them, as of 
December 31,  2013.   For  further  information  on  these  matters,  see  Note 8  to  our  financial  statements 
included  elsewhere  in  this  annual  report.   Despite  these  developments,  we  currently  supply  water  on  a 
wholesale basis to both Diadema and Mauá. 

38 

  
   
  
 
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.  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—The  municipalities  may  terminate  our 
concessions  before  they  expire  in  certain  circumstances.   The  indemnification  payments  we  receive  in 
such cases may be less than the value of the investments we made.”   

In  addition,  we  are  currently  involved  in  litigation  with  respect  to  municipalities  that  intend  to 
expropriate our water and sewage systems, or to terminate concession agreements before paying us any 
indemnification.  For a detailed discussion on these proceedings, see “Item 8.A. Financial Information—
Financial Statements and Other Financial Information—Legal Proceedings.” 

Operations in the City of São Paulo and Certain Metropolitan Regions 

As  of  December 31,  2013,  61  concessions  had  expired  which  jointly  accounted  for  16.1%  of  our 
gross  revenues.   We  entered  into  seven  agreements  in  the  year  ended  December 31,  2013,  bringing  the 
total  number  of  agreements  entered  into  between  2007  and  2013  to  266.   These  seven  new  agreements 
accounted for 1.2% of our total revenues and 1.6% of our intangible assets as of December 31, 2013. 

On  June 23,  2010  the  State  and  the  City  of  São  Paulo  executed  an  agreement  in  the  form  of  a 
convênio,  to  which  we  and  ARSESP  consented,  under  which  they  agreed  to  manage  the  planning  and 
investment for the basic sanitation system of the city of São Paulo on a joint basis.  The principal terms of 
this convênio  were as follows: 

•                     The State and the City of São Paulo would execute a separate agreement with us, granting us 

exclusive rights to provide water and sewage services in the city of São Paulo. 

•                     ARSESP would regulate and oversee our activities regarding water and sewage services in the 

city of São Paulo, including tariffs. 

•                      A  management  committee  (Comitê  Gestor)  would  be  responsible  for  planning  water  and 
sewage  services  for  the  city  and  for  reviewing  our  investment  plans.   The  management 
committee consists of six members appointed for two-year terms.  The State and the City of São 
Paulo  have  the  right  to  appoint  three  members  each.   We  may  participate  in  management 
committee meetings but may not vote. 

In  application  of  the  convênio,  we  executed  a  separate  contract  with  the  State  and  the  city  of  São 
Paulo,  also  dated  June 23,  2010,  to  regulate  the provision of  these  services  for  the  following  30  years.  
The principal terms of this contract are as follows: 

•                      The  total  investment  stated  in  the  contract  must  be  equal  to 13%  of  gross  revenues from  the 
provision  of  services  to  the  city  of  São  Paulo,  net  of  the  taxes  on  revenues,  which  total 
approximately R$600 million per year.   

•                      We  must  transfer  7.5%  of  the  gross  revenues  we  derive  under  the  convênio,  and  subtract 
(i) COFINS  and  PASEP  taxes,  and  (ii) unpaid  bills  of  publicly  owned properties  in  the  city  of 
São  Paulo,  to  the  Municipal  Fund  for  Environmental  Sanitation  and  Infrastructure  (Fundo 
Municipal  de  Saneamento  Ambiental  e  Infraestrutura),   established  by  Municipal  Law 
No. 14,934/2009.  In April 2013, ARSESP postponed the application of such municipal charges 
until the conclusion of the tariff revision process, based on a request from the São Paulo State 
Government to analyze, among other things, methods to reduce the impact on consumers. 

•                     Our investment plan must be compatible with the sanitation plans of the State, the City of São 

Paulo and, if necessary, the Metropolitan region. 

  
   
  
•                     ARSESP will ensure that the tariffs will adequately compensate us for the services we provide 
and  that  tariffs  may  be  adjusted  in  order  to  restore  the  original  balance  between  each  party’s 
obligations and economic gain (equilíbrio econômico-financeiro).  

39 

 
We  currently  have  an  investment  plan  in  place  that  reflects  these  obligations  and  addresses  their 
compatibility with the sanitation plans for the 363 municipalities in which we operate, that include, the 
City of São Paulo and, if necessary, the Metropolitan region.  The investment plan is not irrevocable and 
will  be  reviewed  by  our  management  committee  every  four  years,  particularly  with  respect  to  the 
investments to be executed in the subsequent period. 

Wholesale Operations 

Wholesale Water Services 

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).   Agreements  to  provide  water  services  on  a  wholesale  basis  must  comply  with  the  Basic 
Sanitation Law, which designates these services as “interdependent activities” and regulates each stage of 
the  service.   The  law  requires  that  the  service  be  supervised  by  an  independent  agency,  stipulates 
registration  of  the  cost  of  the  service,  and  requires  assurance  of  payment  among  the  several  service 
providers in order to continue the provision of the services, in accordance with the rules to be published 
by ARSESP.  Our agreements currently comply with the provisions of the Basic Sanitation Law.  In 2013, 
the  revenues  from  wholesale  water  services  were  R$208.7  million.   For  further  information,  see 
“Regulation of Concessions” above. 

Wholesale Sewage Services 

We  provide  sewage  services  on  a  wholesale  basis  to  the  municipalities  of  Mogi  das  Cruzes,  Santo 
André,  São  Caetano,  Mauá  and  Diadema.   Our  agreement  with  Santo  André  for  these  services  was 
executed  with  the  intervention  of  the  Public  Prosecution  Office.   Our  agreements  with  the  other 
municipalities  resulted  from  our  environmental  efforts  and  municipal  authorities’  awareness  of 
environmental  issues.   Through  these  agreements,  in  2013  we  treated  approximately  38  million  cubic 
meters  of  sewage  from  these  municipalities.   We  believe  this  illustrates  our  commitment  to  social  and 
environmental  responsibility.   In  2013,  our  revenues  from  wholesale  sewage  services  were  R$26.1 
million. 

In December 2008, we entered into a five-year agreement for the collection and treatment of 20% of 
the  sewage generated  by  the  city  of  Guarulhos.  We  have  not  yet  started  to provide  these  services, and 
such  services  will  only  commence  when  the  works  on  linking  the  Guarulhos  sewage  to  our  sewage 
system are finalized.  These works are the responsibility the Guarulhos sanitation company. 

Description of Our Activities 

As set forth in Article 2 of our bylaws, we are permitted 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—Public 
Consortia and Cooperation Agreement Law for Joint Management.”  For a description of our operating 
segments please see Note 23 to our financial statements as of and for the year ended December 31, 2013. 

Operating  segments  are  presented  in  our  annual  report  in  a  manner  consistent  with  the  internal 
reporting  provided  to  management,  comprised  of  the  board  of  directors  and  the  board  of  executive 
officers,  pursuant  to  IFRS  8.   Under  Brazilian  GAAP,  prior  to  our  conversion  to  IFRS,  the  financial 
information  for  construction  services  was  not  separately  presented  and  construction  costs  related  to 
concessions were capitalized within property, plant and equipment. As a result, our management did not 
review  the  results  of  this  business.  Following  our  conversion  to  IFRS,  our  management  decided  to 
continue  to  exclude  the  construction  results  from  the  management  reporting  of  our  revenues  and 
expenses,  thus  not  basing  his  decisions  on  discrete  financial  information  for  that  business.   The 

  
   
  
characteristics described in paragraph 5(b) of IFRS 8 for separate operating segments are thus not fulfilled 
for this particular business. Nonetheless, after our conversion to IFRS and for IFRS financial statement 
purposes only, we started to record such results separately as construction revenue and costs under IFRIC 
12.  Although such information is available discretely, however, it is not analyzed by our management as 
such and is not the basis for operational decisions. 

40 

 
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 2013, we produced approximately 
3,053 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

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

•                     water discharged for periodic maintenance of water transmission lines and water storage tanks; 

•                     water supplied for municipal uses such as firefighting; 

•                     water consumed in our own facilities; and 

•                     estimated water loss 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.  For  more  information  on  water  usage  regulation,  see  “—
Water Usage” below.

In order to supply water to the São Paulo metropolitan region, we rely on 20 reservoirs of non-treated 
water and 405 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 73.2 cubic meters per second, which can be treated from the 
interconnected water system  of the São Paulo  metropolitan region.  Average verified production during 
2013 on the interconnected water system of the São Paulo metropolitan region was 69.1 cubic meters per 
second.  The Cantareira, Guarapiranga and Alto Tietê systems, as a whole, supplied 84.3% of the water 
we produced for the São Paulo metropolitan region in 2013. 

In 2013, the Cantareira system accounted for 47.1% 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 73.2% of our gross operating revenues (excluding revenues relating to the construction 
of concession infrastructure) for the year.  The Cantareira System usage rights grant was renewed in 2004 
and  will  expire  in  August  2014.   We  are  working  to  renew  this  grant  for  a  period  of  30  years  and  to 
maintain the current withdrawal basin condition which is of 33 m³/s.  Due to current climate conditions, 
particularly the strong drought, next steps in the renewal process are temporarily suspended.  For further 
information  on  droughts  see  “Item  3.D  Risk  Factors—Risks  Relating  to  Our  Business—Droughts,  the 
water  consumption  reduction  program  or other  measures  may  result  in  a  significant  decrease  in  the 
volume of water billed and the revenues from services we provide, which may have a material adverse 
effect on our company.” 

Water basin committees are authorized to charge both for water usage and the dumping of sewage 
into  water  bodies.   We  participate  in  the  decentralized  and  integrated  management  of  water  resources 
established by the National Policy on Water Resources. We are represented by 150 employees on the 21 
Committees on State Water Basins, on the four Federal Committees that act in the State of São Paulo and 
in  the  National  and  State  Councils  on  Water  Resources.  In  2013,  the  State  Committees  and  part  of  the 
Federal Committees renewed their management for the next two years, and we kept our representation.

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 assure you 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.  

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.  In the cities 
of the interior region of São Paulo, 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 loss, and the installation of new water connections.  We installed 226,421, 
212,775 and 207,840 new water connections in 2013, 2012 and 2011, respectively. 

The interconnected water system of the São Paulo metropolitan region serves 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$4.5 billion (including the investment in the São Lourenço PPP) from 2014 to 2018 to 
increase our water production and distribution capacities as well as to improve the water supply systems.  
In 2013, our total investment in water supply systems amounted to R$1.1 billion. 

Water Treatment 

We  treat  all  water  at  our  water  treatment  facilities  prior  to  placing  it  into  our  water  distribution 
network.   We  operate  232  treatment  facilities,  of  which  the  eight  largest,  located  in  the  São  Paulo 
metropolitan  region,  account  for  approximately  73%  of  all  water  we  produced  in  2013.   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 water transmission lines, ranging 
in  size  from  2.5 meters  to  75 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  water 
transmission lines and the number of connections in our network as of the dates indicated.

More  than  90%  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  transmission  lines  are  mostly  made  of  steel,  cast  iron  or 
concrete. 

As  of  December 31,  2013,  our  water  distribution  pipes  and  water  transmission  lines  included:   (i) 
36,334  kilometers  in  the  São  Paulo  metropolitan  region;  and  (ii) 33,285  kilometers  in  the  Regional 
systems. 

As of December 31, 2013, we had 405 storage tanks in the São Paulo metropolitan region with a total 
capacity of 2 million cubic meters, and 1,879 storage tanks in the Regional systems.  As of that date, we 
had 126 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 transmission lines 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  water  transmission  lines  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  water 
transmission  lines  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 water transmission lines 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 part of the costs of connecting to our water distribution network that is related to 
the connection of customers water pipes that are more than 20 meters away from the water transmission 
lines.   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.

Water Loss 

The difference between the amount of water produced and the amount of water invoiced generally 
represents  both  physical  and  non-physical  water  loss.   The  Non-Revenue  Water  Index  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 loss, divided by (ii) the total amount of water produced by us.   

We  exclude  the  following  from  our  calculation  of  water  loss:   (i) water  discharged  for  periodic 
maintenance of water transmission lines and water storage tanks; (ii) water supplied for municipal uses 
such as firefighting; (iii) water we consume in our facilities; and (iv) estimated water loss associated with 
water we supply to favelas (shantytowns).  

Among the principal indicators utilized to measure rates of water loss are the following: 

•                     Non-Revenue Water (NRW),  in %; 

  
   
  
  
  
  
•                     Water Loss Index (based on metered consumption) (WLI); and 

•                     Index of total loss per connection, (TLDC) in liters/connection per day. 

44 

 
These indicators are calculated by applying the following formulas: 

Vproduced – (Vbilled + Vused) 

NRW  = ______________________________________ 
                                Vproduced 

Vproduced – (Vmicromeasured + Vused) 

WLI  = _____________________________________________________ 
                                             Vproduced 

Vproduced – (Vmicromeasured + Vused) 

TLDC  = _____________________________________________________ 
                                Nconnection x  No. of days of a given period  

Where: 

Vproduced:  corresponds to the volume of water produced at a given period; 

Vbilled:  corresponds to the volume of water billed at a given period; 

Vmicromeasured:  corresponds to the volume of water micromeasured at a given 
period; 

Vused:  corresponds to the volume of water used for operational, public, private 
and social needs (supply shantytown areas) at a given period; and 

Nconnections:  corresponds to the average number of active water connections. 

Since 2005, we have used a method of measuring our water loss based on worldwide market practice 
for  the  industry.   According  to  this  measurement  method,  average  water  loss  is  calculated  by  dividing 
(i) average  annual  water  loss  by  (ii) the  average  number  of  active  water  connections  multiplied  by  the 
number  of  days  of  the  year.   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,  2013,  we  experienced  446  liter/connection  per 
day of water loss in the São Paulo metropolitan region and 261 liter/connection per day in the Regional 
systems,  averaging  372  liter/connection  per  day.   We  plan  to  reduce  total  water  loss  to  around  280 
liters/connection, Non-Revenue Water to 18% by 2020 and the Water Loss Index to 25.7% by 2020. 

Our strategy to reduce water loss has two approaches: 

•                     reduction in the level of physical loss, which results mainly from leakage. To this end we are 
primarily replacing and repairing water transmission lines and pipes, and installing probing and 
other equipment, including strategically located pressure-regulating valves; and  

•                     reduction of non-physical loss, which results 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.  To  this  end  we  are  upgrading  and  replacing  inaccurate  water  meters  and 
expanding our anti-fraud personnel. 

We are taking measures to decrease physical loss by reducing response time to fix leakages and by 
better  monitoring  non-visible  water  transmission  lines  fractures.   Among  other  initiatives,  we  have 
adopted the following measures to reduce physical water loss: 

•                     the introduction of technically advanced valves to regulate water pressure throughout our water 
 transmission  lines  in  order  to  maintain  appropriate  water  pressure  downstream.   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 transmission lines 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 transmission lines as water usage fluctuates.  As of December 31, 2013, we 
had installed 1,912 valves at strategic points in the network, with 1,141 valves being installed in 
the São Paulo metropolitan region and 771 in the Regional systems;  

45 

 
•                      the  reconfiguration  of  interconnected  water  distribution  to  permit  the  distribution  of  water  at 

lower pressure; 

•                     the implementation of routine operational leak detection surveys in high water pressure areas to 

reduce overall water loss; 

•                      the  monitoring  of  and  improved  accounting  with  respect  to  water  connections,  especially  for 

large volume customers;  

•                      regular  checking  on  inactive  customers  and  monitoring  non-residential  customers  that  are 

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

•                     preventing fraud with the use of new, more sophisticated water meters that are more accurate 

and less prone to tampering;  

•                     installing water meters where none are present; and  

•                     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  surface  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 water transmission lines 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 12 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 
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, 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 2013, we did not detect significant algae growth.  We participate in Mananciais/New 
Life,  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  the  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  Nossa  Guarapiranga  and  Pró-Conexão.   See  “—Main  Projects  of  Our  Capital 
Expenditure Program—Metropolitan Water Program—Mananciais/New Life Program,” “—Clean Stream 
Program,” and “—New Policies and Programs—Nossa Guarapiranga.”

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,  removal,  treatment  and  final  disposal  of  sewage.   As  of 
December 31,  2013,  we  collected  approximately  87%  and  77%  of  all  the  sewage  produced  in  the 
municipalities  in  which  we  operate  in  the  São  Paulo  metropolitan  region  and  in the  Regional  systems, 
respectively.   During  2013,  we  collected  approximately  84% of  all  the  sewage  produced  in  the 
municipalities  in  which  we  operated  in  the  State  of  São  Paulo.   We  installed  236,647, 240,687  and 
246,441 new sewage connections in 2013, 2012 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,  2013,  we  were  responsible  for  the  operation  and  maintenance  of 
47,103  kilometers  of  sewage  lines,  of  which  approximately  25,085  kilometers  are  located  in  the  São 
Paulo metropolitan region and 22,018 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, in addition to household 
effluents,  a  portion  of  non-domestic  effluents  (such  as  industrial  sewage  and  sewage  from  other 
non-domestic  sources)  for  treatment  together  with  household  effluents.   Non-domestic  effluents  have 
characteristics that are qualitatively and quantitatively different from household effluents.  As a result, the 
discharge of non-domestic effluents into the public sewage system is subject to compliance with specific 
legal demands with the purpose of protecting the sewage collection and treatment systems, the health and 
safety of operators and the environment.  The current environmental legislation establishes standards for 
the discharge of these effluents into the public sewage system and stipulates that such effluents be subject 
to  pre-treatment.   These  standards  are  defined  in  State  Decree  No. 8,468  dated  September 8,  1976,  as 
amended.   

47 

  
   
  
  
  
  
 
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 producer.  Failure to 
comply  with  these  conditions  can  lead  to  the  application  of  penalties  by  us.   In  extreme  cases,  the 
environmental  protection  agency  (Companhia  Ambiental  do  Estado  de  São  Paulo),  or  CETESB,  is 
notified  in  order  for  the  applicable  measures  to  be  taken.   Effluents  from  our  treatment  facilities  must 
comply with limitation guidelines for release of effluents into receiving water bodies.  Additionally, the 
quality of the water in the receiving water body must not be impaired by the release of such effluents, as 
established by State Decree No. 8,468/76 and Conama Resolutions 357/2005 and 430/2011.  

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 a 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 interior region of São Paulo State 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 lower than in the other 
regions served by us, with approximately 60% of all residences in the coastal region currently connected 
to our sewage network as of December 31, 2013.  

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  2013,  approximately  68%  and  95%  of  the  sewage  we  collected  in  the  São  Paulo  metropolitan 
region  and  the  Regional  systems,  respectively,  or  78%  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  rivers  and  the  Atlantic  Ocean,  in  accordance  with  applicable  legislation.   Though  we  have  not  yet 
reached universalization of sewage collection and treatment services in the regions were we operate, we 
are making efforts to reach this goal. 

We currently operate 500 sewage treatment facilities and 9 ocean outfalls, of which the five largest, 
located in the São Paulo metropolitan region, have treatment capacity of approximately 18 cubic meters 
of sewage per second.  

In the São Paulo metropolitan region, the treatment process used by most treatment facilities is the 

activated sludge process.   

Sewage treatment in the Regional systems will vary according to the particularities of each area. In 
the  interior  region  of  São  Paulo  State,  treatment  consists  largely  of  stabilization  ponds.  There  are  407 

  
   
  
  
  
  
secondary  treatment  facilities  in  the  interior  region  of  São  Paulo  State  that  have  treatment  capacity  of 
approximately  14 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  also  into  the  Atlantic 
Ocean  through  our  ocean  outfalls,  in  accordance  with  applicable  legislation.   We  have  74 sewage 
treatment facilities in the coastal region. 

48 

 
 We are a party to a number of legal proceedings related to environmental matters.  See “Item 8.A. 
Financial Information—Financial 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

Sludge Disposal 

The  creation  of  sludge  is  inherent  to  the  sanitation  cycle.   The  treatment  of  water  and  sewage 
produces residue which needs to be disposed of appropriately to prevent harm to the environment.  Sludge 
removed from the treatment process typically contains water and a very small proportion of solids.  We 
use  filter  presses,  belt  presses,  drying  beds  and  centrifugation  machines,  among  other  processes,  to 
abstract the water from the sludge. 

Currently,  the  sludge  generated  through  our  activity  goes  mainly  to  landfills.  In  turn,  we  treat  the 

slurry generated in these landfills.  

Current  legislation  and  the  population  at  large  demand  advances  in  the  search  for  alternative 
technologies  that  minimize  the  generation  of  and  find  beneficial  uses  for  sludge.   In  light  of  these 
demands, we work on several fronts, seeking innovative approaches to the destination and final disposal 
of sludge.   

Part of the R$6.4 million invested in research and development in 2013 was used for approached to 
the  disposal  and  beneficial  use  of  sludge,  in  order  to  meet  the  Principles  for  Cleaner  Production.   Our 
partnerships  with  the  Brazilian  Innovation  Agency  (FINEP)  and  the  São  Paulo  State  Foundation  for 
Research  Support  (Fapesp)  cover  projects  to  use  of  sludge  to  help  recover  of  degraded  areas,  cover 
landfills and yield sand for construction works.   

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, 2013, 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 with an urban population of approximately 3.5 million.

Competition 

In  the  State  of  São  Paulo,  there  are  approximately  276  municipalities  that  operate  their  own  water 
and  sewage  systems  and  that  collectively  have  a  total  population  of  approximately  13.7  million,  or 
approximately  31%  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. 

The  competition  for  municipal  concessions  arises  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  “—Our  Operations—Regulation  of  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—
Financial  Statements  and  Other  Financial  Information—Legal  Proceedings.”  We  negotiate  expired 
concession  agreements  and  concession  agreements  close  to  expiration  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 tariffs than the ones that agency establishes for regular consumers. 

Billing Procedures 

The procedure for billing and payment of our water and sewage services is largely 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 
loss resulting from faulty water meters.  Sewage billing is included as part of the water bill and is based 
on the water meter reading. 

The  majority  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$1.21  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  2013,  2012  and  2011,  we 
received payment of 95.2%, 94.7% and 94.8%, respectively, of the amount billed to our retail customers, 
and  95.0%,  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  2013,  2012  and  2011,  we  received  100.5%,  100.7%  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 2013, 2012 and 2011, we 
received payment of 45.8%, 50.1% 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 

  
   
  
  
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 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  used  to  take  effect  in 
September.  Pursuant to the most recent tariff revision, both the base date and future adjustments will now 
take place in April. 

Tariffs  have  historically  been  adjusted  once  a  year  and  for  periods  of  at  least  12 months.   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  ARSESP,  which  regulates  and  supervises  the  services  we 
provide  to  the  State  and  also  to  the  municipalities  that  have  agreed  to  its  jurisdiction  through  a 
cooperation agreement. 

In  regards  to  municipalities  that  have  not  explicitly  selected  ARSESP  as  their  regulator,  the  Basic 
Sanitation  Law  allows  the  municipality  to  create  other  regulatory  agencies  of  their  own.   In  2007,  the 
municipality  of  Lins  decided  to  create  its  own  regulatory  authority,  although  it  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 ARSESP.    

In addition, in 2011 municipalities in which the hydrographic basins of the Piracicaba, Capivari and 
Jundiaí  rivers  are  located  created  a  consortium  (ARES/PCJ)  for  the  regulation  and  supervision  of  our 
activities in those areas. As a result of the creation of the ARES/PCJ, we are currently involved in legal 
proceedings in which ARES/PCJ is claiming that it has jurisdiction over the regulation and supervision of 
our activities in two municipalities (Piracicaba and Mombuca). In the municipality of Piracaia, ARSESP 
is the entity responsible for applying the state tariff policy (Decree 41,446/96) which is in force due to an 
existing concession agreement. In the municipality of Mombuca, the regulation and supervision of basic 
sanitation  services  was delegated  to  the State  of  São  Paulo,  so  that ARSESP  could  exclusively  execute 
these services. We cannot predict the outcome of this case or how it may impact our business.  See” Risk 
Factor  –  Risk  Relating  to  Our  Business  -  Current  regulatory  uncertainty,  especially  with  regard  to 
implementation and interpretation of the Brazilian Basic Sanitation Law, may have an adverse effect on 
our business.”   

In 2012 and 2011, we readjusted our prices by 5.15% and 6.83% starting on September 11, 2012 and 
on September 11, 2011, respectively. On April 22, 2013, ARSESP approved a preliminary tariff rate of 
2.3509% to be applied equally on all customer tariffs. These adjustments were valid for all municipalities 
served  by  us,  except  for  the  municipalities  of  Lins  and  Magda,  which  have  different  rules  and 
readjustment dates.  We adjusted the tariffs in the municipality of São Bernardo do Campo pursuant to 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  were  set  so  that  in  September 2012  the  tariff  charged  in  this 
municipality and the tariff charged in the other municipalities of the region became the same. Since then, 
the tariff adjustments in this municipality follow the adjustment calendar of the São Paulo metropolitan 
region. With respect to the municipality of Lins, we adjust our tariff in January according to the variation 
of the IPCA for the last twelve-month period ended November 30.  In Magda, the tariffs will equal the 
tariffs in the region by July 2014.  In the municipalities of Glicério and Torrinha, the tariffs will equal the 
tariffs in the region in 2017.  

On November 1, 2013, ARSESP issued Resolution No. 435 which authorizes us to implement a tariff 
adjustment. Initially, this adjustment considered an inflation rate of 6.2707% as measured by the IPCA 
for the period of August 2012 to July 2013.  From this number, ARSESP deducted the Efficiency Factor 
(X  Factor)  of  0.4297%  for  the  period,  and  this  resulted  in  an  adjustment  of  5.8410%.   Additionally, 
ARSESP estimated the gain that we had with a tariff revision of 2.3509% beginning in April 2013, and 

  
   
  
this  resulted  in  a  further  discount  of  0.9249%  in  the  indicator.   Moreover,  ARSESP  also  estimated  our 
loss of 0.6538% resulting from the delay in the reposition of the IPCA and added that estimated amount. 
The  product  of  these  movements  and  considerations  resulted  in  a  linear  increase  of  3.1451%  in  tariffs 
beginning December 11, 2013.  

51 

 
Regarding the tariff structure, ARSESP Resolution No. 463, published in January 2014, established 
April  10,  2014,  as  a  deadline  for  publication  of  the  timetable  for  implementation  of  our  new  tariff 
structure.  However, in April 17, 2014, ARSESP issued Resolution No. 484, which maintains the current 
Tariff Structure and does not set a date for implementation of the new tariff structure. Until the new tariff 
structure  is  approved  by  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) 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  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, 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  interior  region  of  São  Paulo  State  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 interior region of São Paulo State 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 
interior  São  Paulo  State  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  in  cubic meters  during the 
years and period stated in the São Paulo metropolitan region.

In  2013,  2012  and  2011,  the  average  tariff  calculated  for  the  Regional  systems  was  approximately 

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

The Basic Sanitation Law requires states to establish independent regulators with the responsibility 
of monitoring basic sanitation services and regulating tariffs.  Federal law No. 11,445/07 and São Paulo 
State  Law  No. 1,025/07  established  the  ARSESP,  which  regulates  and  supervises  the  basic  sanitation 
services that we provide in municipalities that have agreed to come under ARSESP’s jurisdiction.  For the 
municipalities  that  have  not  yet  agreed  to  come  under  ARSESP’s  jurisdiction  for  which  we  currently 
provide  basic  sanitation  services,  we  determine  tariffs  based  on  State  Decree  41,446/96.  ARSESP  has 
proposed or enacted a number of regulatory changes, including the following: 

•                      In  2009,  ARSESP  opened  the  methodology  for  tariff  revisions  for  public  discussion  and 
hearings.  In  2010,  ARSESP  issued  Resolution  No. 156.   This  resolution  established  the 
methodology  and  general  criteria  for  the  valuation  of  our  regulatory  asset  base  to  be  used  for 
purposes of  tariff  review  processes  and  auditing.  During 2011  and 2012  ARSESP  held further 
public consultations regarding the methodology for tariff revisions, which was finally specified 
and  disclosed  in  April 2012.   In  November 2012,  ARSESP  published  a  preliminary  technical 
note  for  public  consultation,  proposing  a  preliminary  initial  maximum  average  tariff  (P0)  and 
efficiency  gains  factor  (X  Factor),  based  on  a  preliminary  evaluation  of  assets  held  by  us.  
Following  further  public  consultations,  in  March 2013  ARSESP  published  two  resolutions, 
Resolution No. 406 and Resolution No. 407.  

•                      Resolution  No. 406  sets  out  the  following:   (i) an  initial  maximum  average  tariff  (P0)  and  a 
preliminary asset base value to apply until the conclusion of an external audit of our asset base, 
resulting  in  a  tariff  revision  of  2.3509%;  (ii) authorizes  the  pass-through  to  consumers  of  the 
regulation and  supervision  rate  of  0.5%  immediately  after  the  conclusion  of  the  operational 
adjustments necessary for the inclusion of this rate in the bills in the municipalities where it will 
be  charged;  (iii) ARSESP  also  establishes  an  annual  tariff  adjustment  formula,  to  be 
implemented during the second tariff cycle, consisting of the IPCA variation (a consumer price 
index)  for  the  period,  adjusted  by  an  efficiency  factor  designed  to  transfer  a  portion  of  our 
productivity  gains  to  consumers,  which  was  implemented  on  November  1,  2013  and  further 
adjusted to reflect changes in service quality to be defined and applied as of the third year of the 
tariff cycle.  According to ARSESP’s timetable the final maximum average tariff (P0) would be 
announced in August 2013 after an audit of the asset base value presented by us.  However, it 
was postponed to April 2014.  

•                     A tariff revision of to a rate of 2.3509% was implemented in April 2013 pursuant to Resolution 
No. 406. Additionally,  we  will  pass  an  inspection  fee  of  0.5%  to  consumers  immediately  after 
the conclusion of the operational adjustments necessary for the inclusion of this rate in the bills 
to municipalities where it will be charged. The adaptation of internal processes to accommodate 
this charge has not been finalized yet, and it should be finalized in 2014. 

•                     In April 2013 ARSESP issued Resolution No. 407 authorizing us to pass through to the service 
bill the 7.5% transfer to the São Paulo Municipal Sanitation and Infrastructure Fund as a legal 
charge, as defined by municipal legislation.  Pursuant to the Program Contracts and the Sewage 
and Water Supply Service Contracts, this charge must be considered in the tariff revision. 

•                       In  April 2013,  ARSESP  issued  Resolution  No. 413,  which  effectively  suspended  Resolution 
No. 407  until  the  tariff  revision  process  is  concluded,  thereby  postponing  our  authorization  to 
pass  the  charge  through  to  consumers  on  the  service  bill.  The  postponement  of  Resolution 
No.407 was due to a request from the Government of the State of São Paulo to analyze, among 
other  matters,  methods  of  reducing  the  impact  on  consumers.   Although  Resolution  No.407 
establishes  the  conclusion  of  the  tariff  review  as  the  date  for  the  implementation  of  the  pass-
implemented.   
through,  we  cannot  be  certain  when  Resolution  No. 407  will  be 
In April 2014, ARSESP issued Resolution No. 484, which establishes the conclusion of the tariff 
revision.  No decision was made in relation to the 7.5% charge to our consumers, and we do not 
know when a final decision will be reached.  We cannot know when we will be able to pass the 
7.5% charge to consumers on the service bill. 

  
   
  
•                      In  July  2013,  ARSESP  announced  that  due  to  a  lack  of  quorum  by  its  board  of  directors  to 
deliberate on the tariff revision process, the process would be postponed until a quorum could be 
formed.  Three directors are necessary so that ARSESP may deliberate on any matter and, at that 
time, it only had two directors. 

•                     Resolution No. 427, published by ARSESP on August 1, 2013, maintained suspension of our 
tariff  revision  and  required  that  we  reevaluate  19  points  of  our  Regulatory  Asset  Base.   We 
requested 90 days to assess, clarify and make the adjustments necessary to the Regulatory Asset 
Base.  A  revised  Regulatory  Asset  Base  was  filed  in  December  2013,  in  compliance  with  the 
schedule.  

54 

   
 
•                     In October 2013, ARSESP’s officers fulfilled the minimum requirement quorum necessary to 
deliberate  on  subjects  related  to  the  tariff  adjustment  and/or  revision  that  had  been  paralyzed 
since August 2013.  On November 1, 2013, ARSESP issued Resolution No. 435, authorizing us 
to  implement  a  tariff  adjustment.   Initially,  this  adjustment  considered  an  inflation  rate  of 
6.2707%  as  measured  by  the  IPCA  for  the  period  of  August  2012  to  July  2013.   From  this 
number, ARSESP deducted the Efficiency Factor (X Factor) of 0.4297% for the period, and this 
resulted  in  an  adjustment  of  5.8410%.   Additionally,  ARSESP  estimated  the  gain  that  we  had 
with a tariff revision of 2.3509% beginning in April 2013, and this resulted in a further discount 
of 0.9249% in the indicator.  Moreover, ARSESP also estimated our loss of 0.6538% resulting 
from the delay in the reposition of the IPCA and added that estimated amount. The product of 
these movements and considerations resulted in a linear tariff adjustment of 3.1451% beginning 
December 11, 2013.  

•                      ARSESP  Resolution  No.  463  published  in  January  2014  established  a  new  timetable  for  the 
development of our tariff revision phases and established April 10, 2014, as the date for release 
of the definitive Initial Maximum Price (P0) and the Efficiency Factor (X Factor) for the tariff 
cycle initiated on August 10, 2012. The phases of our tariff revision were determined as follows: 
•          February 11, 2014 – ARSESP released Technical Note RTS 001/2014, which presents 
its  proposals  for  the  definitive  Initial  Maximum  Price  (P0)  and  Efficiency  Factor  (X 
Factor) and start of the public consultation and call for a public hearing. With Technical 
Note RTS 001/2014, ARSESP determined the Final Tariff Level, which consists of: (i) 
the definition of the Final P0, which refers to December 2012, with the definitive initial 
Net  Regulatory  Asset  Base,  or  RAB,  (ii)  the  quantification  of  the  compensatory 
adjustments for retroactive application to the beginning of the cycle, and (iii) the tariff 
amounts to be applied on services rendered as from April 11, 2014. 
•          March 12, 2014 – public hearing and the end of the public consultation;  
•          April 10, 2014 – release and publication of the results related to the definitive Initial 
Maximum Price (P0) and Efficiency Factor (X Factor) and the consolidated reports on 
contributions  from  the  public  consultation;  and  publication  of  the  timetable  for 
implementation  of  our  new  tariff  structure.   However,  on  April  10,  2014,  ARSESP 
suspended the publication of this timetable. 

•          April 17, 2014 – ARSESP issued Resolution No. 484, which, among other things: (i) 
establishes that, as of May 11, 2014, a tariff repositioning index of 5.4408% in relation 
to our current tariffs and an annual Efficiency Factor (X Factor) of 0.9386%, which will 
be  deducted  in  the  upcoming  annual  tariff  adjustments,  shall  be  applied  to  water 
services  bills,  (ii)  allows  us  to  apply  the  repositioning  index  arising  from  the  tariff 
revision  at  a  more  opportune  future  date,  when  we  shall  proceed with  a  recalculation 
and  monetary  adjustment  of  the  applicable  amounts,  in  order  to  ensure  our  economic 
and financial balance, taking into account the atypical situation in our market due to the 
lack of rainfall and our measures to encourage water savings in order to ensure supply, 
(iii) establishes that the next annual tariff adjustments will occur on April 11, 2015 and 
April  11,  2016,  with  the  next  tariff  revision  on  April  11,  2017,  and  (iv)  ratifies  the 
readjustment rules set forth on Resolution No. 406 (described above) and updated the X 
Factor for the tarif cycle from 0.836% to 0.9386%.  The current tariff structure will be 
kept with respect  to  our  services  until  the new  structure is  approved by  ARSESP  and 
implemented.   Considering  what  has  been  established  by  Resolution  No.  484,  we 
decided to postpone the application of the repositioning index to an opportune date no 
later than the end of December 2014. 

In  August 2012,  ARSESP  issued  Resolution  No. 346,  which  established  the  principle  that  users 
should be compensated for any interruptions in water supply.  Implementation of this regulation has been 
suspended  pending  further  technical  discussions.   In  2013,  ARSESP  held  public  consultations  that 
resumed technical discussions on the subject, but the new resolution that will replace Resolution No. 346 
has not yet been published. 

  
   
  
  
  
Marketing Channels 

As  of  December 31,  2013,  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.  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 “—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,  2013,  we  used  1.78%  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.” 

55 

 
Energy  prices  have  a  significant  impact  on  our  results  of  operations.   In  2013,  42.6%  of  our  total 
energy  consumption  occurred  within  the  “free  market,”  where  we  can  more  efficiently  negotiate  the 
supply  of  energy.  In  October 2012,  we  entered  into  long-term  contracts  with  AES  Tiête  (39%)  and 
Tractebel Energia S.A. (61%) to provide these services until 2015.  

Insurance 

We maintain insurance covering, among other things, fire or other damage to our property and 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, 2013, 
we had paid a total aggregate amount of R$5.6 million in premiums.  In addition, we paid R$1.4 million 
for a D&O insurance policy, covering R$4.1 billion in assets, third-party liabilities and D&O insurance.  
We do not have insurance coverage for business interruption risk because we do not believe that the high 
premiums  for  such  insurance  are  justified  by  the  low  risk  of  major  interruption  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.

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  “CSI–  Sistema 
Comercial,  Serviços  e  Informações,”  “AQUALOG  (Control  Water  Treatment  Plants),”  “SGL  (Bid 
Management  System),”  “SCORPION  (Software  to  Operational  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),  “SIA  –  Sistema  de  Informações  de  Auditoria,”  “SAN  –  Sistema  de  Apoio  à 
Navegação,” online software for managing specific articles published in the DAE magazine, Dashboard 
and Online Control of Water Losses.  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 automation 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.

Environmental Matters 

Our environmental policy establishes 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  allows  us  to  develop  a  plan  that  integrates  economic, 
environmental and social dimensions of our work with sustainable use of natural resources. 

  
   
  
  57 

 
We have the following ongoing environmental management programs: 

•         implementation of an Environmental Management System, or EMS, in our water and sewage 

treatment stations (“WTS” and “STS”).  The EMS is present in 95 stations and we have a plan of 
progressive extension until 2020. Additionally, we pursue the ISO 14001 certification for our 
strategic plants.  As of December 31, 2013, we have ISO 14001 certification for 50 STSs; 

•         participation in the Carbon Disclosure Project since 2006; 

•         development of the Corporate Greenhouse Gas Management Program (Programa Corporativo 
de Gestão de Emissões de Gases de Efeito Estufa), in line with the guidelines from the São Paulo 
State Climate Change Policy (PEMC), including the creation of inventories of greenhouse gases, 
totaling six inventories concluded since 2007;  

•          continuation  of  the  actions  set  forth  in  the  corporate  programs  for  obtaining  and  maintaining 

environmental licenses and grants for the right to use water;  

•          the  implementation  of  the  Environmental  Education  Program  (PEA  SABESP),  including  over 
one  hundred  environmental  education  actions  and  projects  involving  the  community  and  other 
stakeholders; 

•          management  of  our  institutional  representation  in  the  State  and  National  Systems  of  Water 
Resources,  including  training  of  company  representatives  to  participate  in:  (i)  the  creation  of 
criteria for water usage charges, (ii) the monitoring of water basin plans (Planos de Bacias), (iii) 
review of water bodies’ classifications,  and (iv) analysis of legislation regarding the protection 
of water sources;  and 

•          implementation  of  the  SABESP  3-Rs  Program  (Programa  SABESP  3Rs)  for  the  reduction, 
re-use  and  recycling  of  waste  of  administrative  activities,  in  partnership  with  the  Catadores 
Cooperatives (Cooperativas de Catadores) and which includes employee training enabling them 
to act as multipliers in the roll-out of the program.   

In  addition  to  corporate  environmental  management  initiatives,  we  have  several  projects  and 
initiatives underway to benefit the environment by engaging the population at large.  In 2013, we invested 
R$32.5 million in environmental programs and projects. 

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, aims 
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 
between 36.1% and 38.9%.  Such targets have not been established for the sanitation sector yet.  We are 
currently developing a Corporate Greenhouse Gas Management Program, aimed at reducing the amount 
of  greenhouse  gases  released  into  the  atmosphere,  including  the  creation  of  an  inventory  to  record 
releases of greenhouse gases.  

In 2013, we concluded the corporate inventories of greenhouse gases for 2011 and 2012, thus totaling 
six  inventories  since  2007.   We  noted  that  the  trend  observed  in  the  previous  inventories  persists, 
specifically  that  activities  regarding  sewage  collection  and  treatment  remain  our  largest  sources  of 
greenhouse  gas  release,  representing  approximately  91%  of  CO2  release.  Electric  energy  represents 
approximately 8% and administrative activities represent approximately 1% of greenhouse gas release.   

  
   
  
  
  
  
  
We participate in initiatives that may potentially reduce the amount of greenhouse gases we release 
into the atmosphere, such as installing a small hydroelectric power plant. The use of biogas generated in 
the treatment of sewage, recycling sewage sludge and covering lagoons, among other actions, are other 
initiatives related to this matter. 

58 

 
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 
related to 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 “—Tariffs.” 

Carbon Disclosure Project 

•                     Carbon Disclosure Project Investors.  We participate in the Carbon Disclosure Project, 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  to  the  project’s 
questionnaires since 2006.   

Physical Effects of Extreme Weather Events 

Since our financial performance is closely linked to climate patterns that influence 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, which could affect 
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 implement new production systems, 
build larger reservoirs, or increase operational capacity by further automating our existing equipment.  To 
increase automation, we would need to purchase and operate new equipment to measure dam levels and 
volumes,  river  output  and  the  rain  in  hydrographic  basins,  create  mathematical  models  for  real  time 
operations, and train technicians to operate these 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  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  power  supply.   Lack  of  electric  energy  could  lead  to 
instability  in  water  supply  and  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 could result in increased salinity in the river estuaries where we 
abstract  water,  which  could  affect  water  treatment  in  these  areas.   Rising  sea  levels  could  also  cause 
damage in our sewage collection network.  

Extreme climate events 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. 

In  this  context,  our  strategy  calls  for  identifying  mitigating  actions,  enlarging  their  coverage  and 
managing  possible  operational  risks  related  to  climate  change,  as  well  as  identifying  opportunities  to 
increase  our  effectiveness  and  to  implement  new  technologies.  The  use  of  biogas  generated  in  the 
treatment  of  sewage  is  an  example  of some  of our  initiatives  related  to  this  matter. With regards  to  the 

  
   
  
risk  of  reduced  water  availability,  we  are  working  to  adapt  to  a  new  scenario  of  water  scarcity  due  to 
climate change through initiatives such as the Corporate Programs for Loss Reduction, the Program for 
Rational Water Usage and the expansion of the planned reutilization of effluents for urban and industrial 
purposes.

Government Regulation 

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

regulation that, among other matters, regulates: 

•                     the granting of concessions to provide water and sewage services; 

•                     the development of public private partnerships; 

•                     the need of a public bidding process for the appointment of private water and sewage services 

providers; 

•                     the need of setting up an agreement for the appointment of public water and sewage services 

providers; 

•                      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; 

•                     minimum requirements for water and sewage services; 

•                     water usage; 

•                     water quality and environmental protection; and 

•                      governmental  restrictions  on  the  incurrence  of  indebtedness  applicable  to  state-controlled 

companies. 

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 to 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. 

60 

 
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,  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 (as amended by Federal Decree No. 8,211/14), regulating the Basic Sanitation Law.  See “Item 
3.D.  Risk  Factors—Risks  Relating  to  our  Business—Current  regulatory  uncertainty,  especially  with 
regard to implementation and interpretation of the Brazilian Basic Sanitation Law, may have an adverse 
effect on our business.”   

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  and,  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).  

Federal  Decree  No. 7,217,  which  was  enacted  on  June 21,  2010,  (as  modified  by  Federal  Decree 
No. 8,211  of  March  21,  2014)  and  Law  11,445  implemented  a  first  series  of  new  principles  under  the 
Basic Sanitation Law, including the following: 

•                      for  public-public  partnership  contracts  (or  program  contracts),  public  hearings  must  be  held 
with respect to bid announcements, and technical and economic viability studies must be carried 
out; 

•                       the  rights  and  obligations  of  customers  and  service  providers,  including  penalties,  are 
determined by the owner of the public service, not by the regulatory agency (since its function is 
to ensure full compliance of legislative and contractual conditions); 

•                     the regulatory agency’s function is to ensure compliance with the law and with the contractual 

conditions; 

  
   
  
 61 

 
•                      the  technical  and  financial  viability  of  the  provision  of  water  and  sewage  services  should  be 
determined  based  on  (i)  capital  contributions  necessary  to  offer  the  services  and  (ii)  expected 
revenues from the provision of the service; and 

•                     when a regulated service is to be provided by different service providers, those providers must 

execute an agreement regulating their respective activities. 

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: 

•                     category of use; 

•                     capacity of the water meter; 

•                     characteristics of consumption; 

•                     volume consumed; 

•                     fixed and floating costs; 

•                     seasonal variations of consumption; and 

•                     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. 

  
   
  
62 

 
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 loss 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. 

Furthermore,  since  Law  No. 11,445  permits  municipalities  to  create  their  own  regulatory  agencies 
rather  than  being  subjected  to  overview  by  ARSESP,  a  number  of  municipalities  created  their  own 
regulatory  agencies.   The  municipality  of  Lins,  which  decided  in  2007  to  create  its  own  regulatory 
authority, revisited this decision in 2010 and transferred the regulation of water activities, including the 
setting of tariffs, to ARSESP.  The municipality of Lins has retained, however, the power to ultimately 
approve the tariff set by ARSESP. 

In addition, in 2011 municipalities in which the hydrographic basins of the Piracicaba, Capivari and 
Jundiaí  rivers  are  located  created  a  consortium  (ARES/PCJ)  for  the  regulation  and  supervision  of  our 
activities in those areas. As a result of the creation of the ARES/PCJ, we are currently involved in legal 
proceedings in which ARES/PCJ is claiming that it has jurisdiction over the regulation and supervision of 
our activities in two municipalities (Piracicaba and Mombuca). In the municipality of Piracaia, ARSESP 
is the entity in charge of applying the state tariff policy (Decree 41,446/96) which is in force due to an 
existing concession agreement. In the municipality of Mombuca, the regulation and supervision of basic 
sanitation  services  was delegated  to  the State  of  São  Paulo,  so  that ARSESP  could  exclusively  execute 
these services. We cannot predict the outcome of this case or how it may impact our business.  See” Risk 
Factor  –  Risk  Relating  to  Our  Business  -  Current  regulatory  uncertainty,  especially  with  regard  to 
implementation and interpretation of the Brazilian Basic Sanitation Law, may have an adverse effect on 
our business” 

ARSESP Rule Enactments  

In 2009 ARSESP enacted rules regarding the following: 

•                     general terms and conditions for water and sewage services; 

•                     procedures for communication regarding any failure in our services; 

•                     penalties for deficiencies in the provision of basic sanitation services; and  

•                     procedures for confidential treatment of our customers’ private information. 

Consumer Relations in the State of São Paulo 

In 2011 ARSESP altered the standard contract that we are required to use in our relationships with 
retail customers, requiring that invoices be sent to the consumer of the service rather than the owner of the 
property.   We  estimate  that  this  change  will  affect  ongoing  legal  disputes,  particularly  those  regarding 
collection  procedures,  as  well  as  business  discussions  in  general.   Since  this  change  is  still  being 
implemented, we are not currently able to predict its impact on our business.  

Regarding changes to the communication process for the reporting of failures, 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  ARSESP,  which  introduces  greater 
transparency and control to our operations.  

  
   
  
63 

 
In  2013,  we  established  procedures  for  communicating  scheduled  interruptions  in  the  provision  of 
water  services  by  developing  the  Communication  of  Scheduled  Interruptions  of  Basic  Sanitation  – 
SISCIP-S.    

We are currently evaluating the enforceability and legality of some of these rules.  Implementation of 
these rules started during 2011, is currently ongoing, 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 in ways we cannot currently predict.  

We  are  attentive  to  these  regulatory  changes,  have  been  working  toward  meeting  ARSESP’s 
requirements  and  recommendations,  and  have  presented  technical,  legal  and  factual  reasons  for  any 
conduct that 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—“Current  regulatory  uncertainty, 
especially with regard to implementation and interpretation of the Brazilian Basic Sanitation Law, may 
have an adverse effect on our business.” 

Regulation of 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 
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  any  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.   The  Basic 
Sanitation Law reduced the maximum time period for payment of indemnification in such cases to four 
years.  See “Item 3.D. Risk Factors—Risks Relating to Our Business—The municipalities may terminate 
our concessions before they expire in certain circumstances.  The indemnification payments we receive in 
such cases may be less than the value of the investments we made.” 

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.   In  addition,  there  are  pending  cases  before  the  Brazilian  Supreme  Court 
regarding  whether  the  right  to  execute  concession  and  program  agreements  in  the  metropolitan  regions 
belongs  to  the  State  or  the  municipal  government.  On  February 28,  2013  the  Brazilian  Supreme  Court 
decided a pending case on this matter related to the State of Rio de Janeiro.  A majority of the court held 
that  the  State  and  municipal  governments  must  set  up  new  joint  entities  to  oversee  the  planning, 
regulation and auditing of basic sanitation services in metropolitan regions.  On March 6, 2013, the court 
ruled that this decision would come into effect after a 24-month period with respect to the State of Rio de 

  
   
  
Janeiro. The São Paulo metropolitan region accounted for 73.2% of our gross operating revenue in 2013 
(excluding revenues relating to the construction of concession infrastructure).  We cannot predict how the 
shared management of these operations will be carried out in the São Paulo metropolitan region and other 
metropolitan  regions  we  operate  in  or  what  effect  it  may  have  on  our  business,  financial  condition  or 
results of operation.  See “Item 3.D. Risk Factors—Risks Relating to Our Business—Current regulatory 
uncertainty, especially with regard to implementation and interpretation of the Brazilian Basic Sanitation 
Law, may have an adverse effect on our business.” 

64 

 
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 power to grant and monitor formal concessions for water and sewage services in the 
city of São Paulo.  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.  See  “Item 3.D.  Risk  Factors—Risks 
Relating to Our Business—The terms of our agreement to provide water and sewage services in the City 
of São Paulo could have a material adverse effect on us.”   

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. 

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.  On  August  5,  2009,  the  State  of  São  Paulo  enacted 
Decree No. 54,644, which revoked Decree No. 50,868 and regulated the composition, organization and 
operation  of  the  State  Sanitation  Council  (Conselho  Estadual  de  Saneamento  –  CONESAN)  created  by 
Supplementary Law No. 7,750/92. 

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  ARSESP  and  partially  revoked 
Supplementary  Law  No.  7,750/92.   Furthermore,  Supplementary  Law  No. 1,025/2007  maintained  the 
State Sanitation Council, 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. 

  
   
  
65 

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

municipal jurisdictions and prerogatives, and is responsible for:   

•                     the compliance with and enforcement of state and federal basic sanitation legislation; 

•                     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; 

•                     the acceptance, where applicable, of the legal attributions of the jurisdictional authority; 

•                     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 

•                      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, 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,  ARSESP  charges  0.50%  of  the  annual  total  invoice  from  gross  operating  revenue 
(excluding  revenues  relating  to  the  construction  of  concession  infrastructure)  of  the  municipality.   This 
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 to: 

•                     participate in the controlling block or the capital of other companies; 

•                     create subsidiaries, which may become majority or minority shareholders in other companies; 

and 

•                      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 Public-Private Partnership (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 conditioned upon performance.  The payment may be collected through:  (i) tariffs paid 
by  users;  (ii) use  of  resources  from  the  budget;  (iii) assignment  of  credits  belonging  to  the  State; 

  
   
  
(iv) transfer of rights related to the commercial exploitation of public assets; (v) transfer of real property 
and other property of assets; (vi)  public debts securities; and (vii) other revenues. 

  66 

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

from the budget. 

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 
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: 

•                     the technical quality of the proposal;  

•                     lowest cost or lowest public service tariff offered;  

•                     a combination of the criteria above; or  

•                     the largest amount offered in consideration for the concession. 

The  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: 

•                     rational utilization of water resources, ensuring that their primary use is to supply water to the 

population;  

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

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

•                     defense against critical hydrological events which could cause risk to the health and safety of 

the population or economic and social losses;  

•                     development of hydro-transportation for economic benefit;  

•                      development  of  permanent  programs  of  conservation  and  protection  of  underground  water 

against pollution and excessive exploitation; and  

•                     prevention of soil erosion in urban and rural areas, with a view to protecting against physical 

pollution and silting of water resources. 

  
   
  
Among  other  instruments  established  by  this  Policy,  the  competent  public  authority  grants  for  the 
right  to  use  water  for  the  implementation  of  any  enterprise  that  demands  the  use  of  surface  or 
underground  water  resources  (for  the  collection  or  release  of  effluents),  as  well  as  for  the  execution  of 
services that alter the regime or quality of such water resources.  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.   

67 

 
In  conducting  our  principal  activities,  we  have  grants  for  the  rights  to  use  water,  and  there  is  a 
corporate program in place to obtain and maintain the rights to use water for the remaining activities.  As 
of  the  date  of  this  annual  report,  we  do  not  own  all  the  required  grants  for  the  right  to  use  water  in 
connection with our operations.  However, all of our water-usage activities have filed requests for grants 
for  the  right  to  use  water  with  the  competent  authority;  many  of  these  requests  have  been  granted  and 
others are under analysis by DAEE and ANA.   

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  participation  of  the  Water  Basins  Committees,  the 
formulation  of  criteria  by  such  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. 

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. 

Charging for the use of water is under gradual implementation by the State of São Paulo, where the 
largest individual contributors are located, and it is a management tool of the Policy on Water Resources 
to promote the rational use of water and finance programs and actions established by the basin plans.  In 
2013, we paid about R$27.0 million for the use of water resources. 

Charging  for  the  use  of  water  from  rivers  of  federal  domain  began  in  2003  in  the  Paraíba  do  Sul 
basin, and charging for the use of water from rivers of state domain began in 2007 in the Paraíba do Sul, 
Piracicaba,  Capivari  and  Jundiaí  basins.   Subsequently,  charges  were  implemented  for  the  use  of  water 
from the Sorocaba, Middle Tietê and Santos Region basins.  In 2013, charges were implemented for the 
use  of  water  from  the  Baixo  Tietê  basin  and,  in  April  2014,  for  the  use  of  water  from  the  Alto  Tietê 
Basin.  It is probable that the same will occur in 2014 in the following basins: Tietê/Batalha, Tietê/Jacaré, 
Baixo  Pardo  e  Grande,  Litoral  Norte,  Mogi-Guacu,  Pardo,  Pontal  do  Paranapanema,  Sapucaí 
Mirim/Grande, Serra da Mantiqueira, Ribeira do Iguape/Litoral Sul and Turvo/Grande.  In 2015, charges 
for the use of water are expected to be implemented for the basins of Alto Paranapanema, Aguapeí/Peixe, 
Médio Paranapanema and São José dos Dourados. 

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.   

68 

 
The control and environmental planning instruments are defined by several legal instruments, such as 
State  Law  No. 997/1976,  which  regulates  environmental  pollution  control;  CONAMA  Resolution 
No. 05/1988,  which  requires  licensing  of  sanitation  projects  that  cause  significant  alterations  to  the 
environment;  CONAMA  Resolution  No. 237/1997,  which  regulates  (i) environmental 
licenses, 
(ii) 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;  State  Decree  No. 8,468/76, 
CONAMA  Resolution  No. 357/2005,  and  CONAMA  Resolution  No. 397/08,  which  establish  standards 
of  quality  for  receiving  bodies  of  water;  Decreto  Estadual  8,468/76  and  CONAMA  Resolution 
No. 430/11 which establish the standards for discharge of effluents; and Portaria Departamento de Águas 
e Energia Elétrica 717/96, which regulates the concession of grants for the right to use water and rights to 
interfere in water resources.   

Projects  with  significant  environmental  impact  are  subject  to  specific  studies  prepared  by 
multidisciplinary  teams  that  present  a  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:    

•                      preliminary  license  –  granted  in  the  planning  stage,  approving  the  location  and  concept  and 

attesting to the project’s environmental feasibility; 

•                      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 

•                     operation license – authorizing the operation of a unit or activity, subject to compliance with 

the technical requirements contained in the installation license. 

We  have  been  implementing  a  program  (Programa  Corporativo  de  Manutenção  e  Obtenção  do 
Licenciamento Ambiental) since 2010, in order to comply with environmental regulation by 2016.  As of 
the date of this annual report, we were not in possession of all licenses required in connection with our 
operations.    

Sewage Requirements 

State  law  sets  forth  regulations  regarding  pollution  control  and  environmental  preservation  in  the 
State of São Paulo.  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, as is the case for industrial enterpresises.  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.   Effluents  from  our  treatment  facilities 
must  comply  with  effluent  limitation  guidelines  and  meet  the  water  quality  standards  of  the  receiving 
water bodies established by federal and state legislation.  See “—Sewage Operations—Sewage System”.  

The CETESB is authorized under State law to monitor discharges of effluents into the water bodies, 
among  other  things.   The  CETESB  also  issues  the  environmental  licenses  to  the  polluting  sources, 
including  sewage  treatment  stations.   For  more  information,  see  “Item  4.B.  Business  Overview—
Environmental Matters.” 

State  and  federal  water  resource  legislation  establishes  the  charging  of  fees  for  the  discharge  of 
treated  effluents  into  water  bodies.   This  charge  is  already  in  force  for  some  water  basins,  and  it  is  in 
different  implementation  stages  for  the  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  external  credit  operations  (i.e.,  foreign  currency  borrowings)  of  states,  the 
Federal  District  of  Brasilia,  municipalities  and  their  respective  autarquias  (agencies),  foundations  and 
non-financial  companies,  including  us.   This  resolution  provides,  among  other  things,  that,  with  certain 
exceptions applicable to the importation of goods and services: 

•                      the  proceeds  of  external  credit  operations  must  be  exclusively  used  to  refinance  outstanding 
financial  obligations  of  the  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 

•                     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  dated  as  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  as  of  March 2,  2006,  and  amended  State  Law  No. 119,  dated  as  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  consortia.   In  addition,  this  law 
permits  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.

D.      Property, Plant, Equipment and Intangible Assets 

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 transmission lines, 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,  2013,  we  operated  through  69,619 
kilometers of water pipes and water transmission lines and 47,103 kilometers of sewer lines.  As of that 
same date, we operated 232 water treatment facilities and 509 sewage treatment facilities (including nine 
ocean outfalls), 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.  As of 
December 31, 2013, we held assets in the amount of R$249.0 million pledged as collateral to 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.  The debt owed to 
the PAES Program was entirely paid in 120 months, and the last installment was paid on June 28, 2013.  

As  of  December 31,  2013,  the  total  net  book  value  of  our  property,  plant  and  equipment  and 

intangible assets (including concession assets) was R$24,045.7 million. 

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

ITEM 5.            OPERATING AND FINANCIAL REVIEW AND PROSPECTS 

The following management’s discussion and analysis of financial condition and results of operations 
should  be  read  in  conjunction  with  our  audited  financial  statements  included  elsewhere  in  this  annual 
report.   The  financial  statements  included  elsewhere  in  this  annual  report  have  been  prepared  in 
accordance  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,  2013,  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  362  municipalities  in  the  State  of  São 
Paulo,  which represented 56%  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  in which we did not 
operate water distribution 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 21 million, the São Paulo metropolitan region 
accounted  for  73.2%,  74.2%  and  74.0%  of  our  gross  operating  revenue  in  2013,  2012  and  2011 
(excluding  revenues  relating  to  the  construction  of  concession  infrastructure),  respectively.   As  of 
December 31, 2013, 56.9% of the concession intangible assets reflected on our balance sheet were 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 operating revenue, 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, 
control costs and improve productivity, general economic conditions in Brazil and abroad and, in some 
periods, meteorological conditions. 

Our results of operations for the 2013, 2012 and 2011 fiscal years were affected by a provision for 
severance  payments  in  the  amount  of  R$21.3  million  for  employees  who  resigned  in  2013, 
R$49.9 million in 2012 and R$47.0 million in 2011. 

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 are responsible for setting, adjusting and reviewing tariffs, taking into 
consideration, among other factors, the following: 

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

•                     anti-inflation measures enacted by the federal government from time to time; and 

•                      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 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. 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 the economic activity and the inflation 
rate.  For example, the general performance of the Brazilian economy may affect our cost of capital and 
inflation may affect our costs and margins.  The Brazilian economic environment has been characterized 
by significant variations in economic growth rates.  However, as our product is viewed as essential, our 
sales revenue has demonstrated high stability over the past three years. 

General Economic Conditions 

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. 

  
   
  
  
  
  
72 

 
In  2012,  Brazilian  GDP  increased  0.9%  in  comparison  with  2011.   At  that  same  year,  Brazil  had 
US$378 billion  in  currency  reserves  and  its  trade  surplus  was  US$19.4 billion.   The  average 
unemployment rate in Brazil’s principal metropolitan regions was 5.5% in 2012, the lowest it has been 
since March 2002. 

In 2013, Brazilian GDP increased 2.3% in comparison with 2012.  Also in 2013, Brazil had US$375 
billion in currency reserves and its trade surplus was US$2.6 billion, the worst in 13 years, and its trade 
balance  fell  86%  in  comparison  with  2012.   The  average  unemployment  rate  in  Brazil’s  principal 
metropolitan  regions  was  5.4%,  the  lowest  rate  in  history  according  to  the  Brazilian  Institute  of 
Geography and Statistics (Instituto Brasileiro de Geografia e Estatística), or IBGE. 

Interest Rates 

In 2011, until the month of August, the Central Bank continued increasing the SELIC rate, reaching 
12.50% in July.  In the month of August, the Central Bank started decreasing the SELIC, closing 2011 at 
11.00%.  This downward trend was maintained in 2012, with the SELIC rate closing the year of 2012 at 
7.25%.  In 2013, the SELIC rate was kept at 7.25% until April, after which the Central Bank started to 
gradually raise it. The SELIC rate at December 31, 2013 was 9.9%.  

With respect to our foreign currency-denominated debt, in 2013 we experienced stability in the cost 
of debt linked to floating interest rates as compared to 2012, but with an upward trend beginning in the 
second half of 2013. With regards to our fixed-rate foreign currency denominated capital market debt, the 
reduction in secondary market earnings in 2012 continued during the first half of 2013.  By the beginning 
of the third quarter, this yield rose, returning to 2010-2011 levels similar to those existing at the time of 
our 2010 Eurobond issuance. 

We  have  not  utilized  any  derivative  financial  instruments  or  any  hedging  instruments  to  mitigate 
interest rate fluctuations. However, we prioritize long term debt in foreign currency alongside multilateral 
organizations  and  official  foreign  government  agencies  and  take  advantage  of  market  opportunities  to 
preform “liability management” to reduce cost and anticipate refinancing situations. 

Inflation 

Inflation affects our financial performance by increasing our costs of services rendered and operating 
expenses.   Part  of  our  real-denominated  debt  is  directly  indexed  to  take  into  account  the  effects  of 
inflation. Additionally, we are exposed to the mismatch between the inflation adjustment indices of our 
loans  and  financing  and  those  of  our  receivables.  Water  supply  and  sewage  service  tariffs  do  not 
necessarily follow the increases in inflation adjustment and interest rates affecting our debt.  We cannot 
assure you that our tariffs will be increased, in future periods, to offset, in full or in part, the effects of 
inflation.   

Inflation  adjustments  derive  from  collections  from  or  payment  to  third  parties,  as  contractually 
required by law or court decision, and are recognized on an accrual basis. Inflation adjustments included 
in  these  agreements  and  decisions  are  not  considered  embedded  derivatives,  since  they  are  deemed  as 
inflation adjustments for us. See Notes 3.20, 4.3.1 and 26 of the Financial Statements for the impacts of 
inflation adjustments on our financial performance and debt. 

Currency Exchange Rates 

to  our  current  portion  of  our 

We  had  total  foreign  currency-denominated  indebtedness of  R$3,698.6 million  as  of December 31, 
long-term  foreign 
2013,  of  which  R$216.0  million  relates 
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  is  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.  In 2011, the 12.6% depreciation of the real against the U.S. dollar 
and  the  18.6%  depreciation  of  the  real  against  the  yen,  respectively,  led  to  a  foreign  exchange  loss  of 
R$382.3 million.  In 2012, the 8.94% depreciation of the real against the U.S. dollar offset by the 2.4% 

  
   
  
appreciation of the real against the yen, respectively, led to a foreign exchange loss of R$50.5 million.  In 
2013, the 14.64% depreciation of the real  against the U.S. dollar offset by the 5.91% appreciation of the 
real   against  the  yen,  respectively,  led  to  a  foreign  exchange  loss  of  R$267.8  million.   However,  since 
most of our debt denominated in foreign currencies is long-term debt with a long amortization schedule, a 
devaluation of the real would principally impact cash flows regarding the current portion of our long-term 
debt.  

 73 

 
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.

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.   During  the  years  ended  December 31,  2013,  2012  and  2011  we  had  no  forward 
exchange transactions. 

Effects of Extreme Weather Events – Drought 

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%.   In  March 2004  when  our  reservoirs  were  at  extremely  low  levels,  we  implemented  a  water  usage 
reduction  bonus  program.   After  returning  to  normal  rainfall  levels,  which  occurred  between  2004  and 
early 2005, the condition of our reservoirs improved.  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.     

Part of the Brazil’s Southeastern region, in particular the southern region of Minas Gerais State and 
the  Piracicaba  river  basin,  from  which  we  extract  the  water  used  in  the  Cantareira  System,  and  the 
northern area of the São Paulo metropolitan region have been experiencing below average rainfall since 
2012,  which  worsened  at  the  end  of  2013  and  beginning  of  2014.   With  rainfall  significantly  below 

  
   
  
  
  
  
  
  
  
average, there has been a reduction in the level of water stored during the rainy season, from October to 
March,  in  the  reservoirs  of  the  Cantareira  System,  which  is  the  largest  system  of  the  São  Paulo 
metropolitan region.  In order to minimize the effects of this drought, in February 2014, we approved a 
program  that  incentivizes  water  consumption  reduction,  based  on  a  bonus  system,  pursuant  to  which 
customers  who  achieve  their  consumption  reduction  goal  (20%  water  consumption  reduction)  will  be 
entitled  to  a  30%  discount  on  their  service  bill.   Initially,  this  incentive  program  was  scheduled  to  last 
seven months from February 1, 2014 or until the water level in the reservoirs is normalized.  However, in 
April 2014 the incentive program was extended for the entire São Paulo metropolitan region until the end 
of 2014 or until the water level in the reservoirs is normalized.  For more information on droughts, see 
“Item  3.D  Risk  Factors—Risks  Relating  to  Our  Business—Droughts,  the  water  consumption  reduction 
program  or other  measures  may  result  in  a  significant  decrease  in  the  volume  of  water  billed  and  the 
revenues from services we provide, which may have a material adverse effect on our company.” 

74 

 
As  of  December 31,  2013,  the  reservoirs  in  the  São  Paulo  metropolitan  region,  where  our  largest 
market is located, had a utilization rate of 41%, compared to a 50.6% utilization rate as of December 31, 
2012. 

Critical Accounting Estimates and Judgments 

We make estimates and judgments concerning the future.  The resulting accounting estimates will, by 
definition, seldom  equal  the  related  actual  results.   The  estimates  and judgments  that  have  a  significant 
risk  of  causing  material  adjustment  to  the  carrying  amount  of  our  assets  and  liabilities  within  the  next 
financial year are mentioned 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 3.4 to our financial statements as of December 31, 2013 and 2012 and 
for  the  years  ended  December 31,  2013,  2012  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$103.9 million, R$192.3 million and R$120.3 million in 2013, 2012 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. 

Valuation of Long-Lived Assets 

As  of  December 31,  2013, we  had property,  plant and  equipment  and  intangible  assets  of  R$199.5 

million and R$23,846.2 million, respectively. 

Property, plant and equipment, intangibles and other noncurrent assets with definite useful lives, are 
reviewed  annually  for  impairments  or  whenever  events  or  changes  in  circumstances  indicate  that  the 
carrying amount may not be recoverable.  The Company does not have assets with indefinite useful lives 
and concluded that there are no indications of impairment losses. 

We recognize intangible assets arising from concession contracts under IFRIC 12.  We estimate 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, is 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.  

75 

  
   
  
  
 
The fair value of construction and other work on the infrastructure is recognized as revenue, at its fair 
value,  when  the  infrastructure  is  built,  provided  that  this  work  is  expected  to  generate  future  economic 
benefits.   The  accounting  policy  for  the  recognition  of  construction  revenue  is  described  in  Note  3.3 
“Operating Revenue.” 

Intangible assets related to concession agreements 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, whichever is shorter. 

Investments  made  and  not  recovered  through  rendering  of  services,  within  the  terms  of  our 
agreement, must be indemnified by the concession grantor; (1) with cash or cash equivalents or also, in 
general, (2) with a contract extension.  These investments are amortized over the useful life of the asset. 

Law  11445/07  prescribes  that,  whenever  possible,  basic  sanitation  public  utilities  shall  have  their 
economic and financial sustainability ensured through the consideration received from service collection, 
preferably  as  tariffs  and  other  public  charges,  which  may  be  established  for  each  service  or  both.  
Therefore,  investments  made  and  not  recovered  through  these  services,  within  the  original  term  of  the 
contract,  are  recorded  as  intangible  assets  and  amortized  over  the  useful  life  of  the  asset,  taking  into 
consideration a solid track record of concession renewal and, therefore, the continuity of services. 

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 
amortization  of  intangible  assets  and  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 amortization of intangible assets and remaining useful lives of the underlying 
assets and can have a significant impact on the results of operations. 

Provision 

As of December 31, 2013, we were party to judicial and administrative proceedings, relating to civil, 
environmental  and  tax  matters,  amounting  to  R$1,180.4  million  (deducting  the  amount  of  R$309.5 
million related to escrow 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$3,244.5 million, and those with respect to which we considered the risk of loss as remote amounted to 
R$34,179.7 million. 

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 
18 to our financial statements as of December 31, 2013 and 2012 and for the years ended December 31, 
2013, 2012 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 risks, actual losses realized in future periods could differ significantly 
from our estimates and could exceed the amounts which we have provisioned. 

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.   The  assumptions  used  in  determining  the  net  cost 
(income) for pensions include a discount rate and a  mortality table.  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.   The  discount  rate  was  increased  from  4.0%  in  2012  to  6.46%  in  2013 
under Plan G0 and from 4.1% in 2012 to 6.36% in 2013 under Plan G1 in order to follow the decrease in 

  
   
  
the rates applicable to the Brazilian Government NTN – B, long term notes, which term is similar to the 
duration of the pension benefits, as described in Notes 3.19 (a) and 19 (b) to our financial statements as of 
December 31, 2013 and 2012 and for the years ended December 31, 2013, 2012 and 2011. 

76 

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

Additional information on the pension plans under Plan G0 and G1is disclosed in Note 19. 

Deferred income tax and social contribution 

The  Company  recognizes  and  settles  taxes  on  income  based  on  the  results  of  operations  verified 
according  to  the  Brazilian  Corporate  Law,  taking  into  consideration  the  provisions  of  the  tax  laws.  
Pursuant to IAS 12, the Company recognizes deferred tax assets and liabilities based on the differences 
between the accounting balances and the tax bases of assets and liabilities.   

The Company regularly reviews the recoverability of deferred tax assets and recognizes a provision 
for impairment if it is probable that these assets will not be realized, based on historic taxable income, the 
projection  of  future  taxable  income  and  the  estimated  period  to  reverse  temporary  differences.   These 
calculations require the use of estimates and assumptions.  The use of different estimates and assumptions 
could result in provision for impairment of all or a significant amount of deferred tax assets. 

As  of  December 31,  2013  and  2012,  we  have  recognized  R$114.0  million  and  R$145.3 million, 
respectively, as deferred income tax assets, net of the deferred tax liabilities, as disclosed in Note 17 to 
our financial statements as of December 31, 2013 and 2012 and for the years ended December 31, 2013, 
2012 and 2011. 

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 
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 9  to  our  financial  statements  as  of  December 31,  2013  and  2012  and  for  the  years  ended 
December 31, 2013, 2012 and 2011 and “Item 7.  Major Shareholders and Related Party Transactions.”

As  of  December  31,  2013  and  2012,  the  amounts  not  recorded  related  to  pension  benefits  paid  on 
behalf  of  the  State  by  the  Company,  totaled  R$1,412.5  million  and  R$1,351.2  million  respectively, 
including the amount of R$696.3 million related to the transfer of the reservoirs in the Alto Tietê system. 
As a result, the Company also recognized the obligation related to pension benefits, maintained with the 
beneficiaries  and  pensioners  of  Plan  G0.  As  of  December  31,  2013  and  2012,  the  pension  benefit 
obligations  of  Plan  G0  totaled  R$1,780.3  million  and  R$1,987.7  million,  respectively.  For  detailed 
information on the pension benefit obligations refer to Note 19 of our Financial Statements. 

Accounts Receivable from the State for Water and Sewage Services Rendered 

Certain  of  these  accounts  receivable  have  been  overdue  for  a  long  period.   We  have  entered  into 
agreements  with  the  State  with  respect  to  these  accounts  receivable.   For  further  information  on  these 
agreements, see Note 9 to our financial statements as of December 31, 2013 and 2012 and for the years 
ended  December 31,  2013,  2012  and  2011  and  “Item 7.  Major  Shareholders  and  Related  Party 
Transactions.” 

Use of Certain Assets  

Empresa  Metropolitana  de  Águas  e  Energia  S.A.  –  EMAE  plans  to  receive  credit  and  to  obtain 
financial compensation for the use of water from the Guarapiranga and Billings reservoirs, which we use 
in our operations, as well as reimbursement of damages related to non-payment in due course.  

We understand that no amounts are due for the use of these reservoirs given the grants already made.  
Should these reservoirs not be available for our use, there could be a need to collect water in more distant 
locations and a risk of not being able to properly render services in the region and an increase in water 
supply cost.  

Several lawsuits were filed by EMAE, among them a lawsuit to enforce an arbitration clause related 
to  the  Guarapiranga  reservoir,  a  proceeding  which  has  already  begun  and  another  lawsuit,  pleading  for 
financial compensation due to our water abstraction from the Billings reservoir for public supply.  These 
two  lawsuits  allege  that  this  conduct  has  caused  permanent  and  increasing  loss  in  the  capacity  of  the 
Henry Borden hydroelectric power plant to generate electricity as well as financial losses.  

We understand that the expectation for all cases is of possible losses, and for the time being, it is not 

feasible to estimate the amounts involved, since they were not determined.  

On  April  10,  2014,  we  issued  an  Announcement  to  the  Market  to  communicate  that  we  are 
negotiating  with  EMAE  regarding  a  potential  future  agreement.   However,  no  adjustment  has  been 
confirmed, and no agreement has been executed by either party as of yet.

Year Ended December 31, 2013 Compared to Year Ended December 31, 2012 

        We restated our financial statements as of and for the years ended December 31, 2012 and 2011 
as  a  result  of  the  adoption,  as  of  January  1,  2013,  of  two  new  standards  issued  by  the  IASB:  IAS  19 
(Employee Benefits – as revised in 2011) and IFRS 11 (Joint Arrangements).  These new standards were 
applied retrospectively to 2012 and 2011 pursuant to IAS 8 (Accounting Policies, Changes in Accounting 
Estimates  and Errors) for  comparison purposes.   The adoption  of  these new  standards  impacted  several 
line items of our financial statements.  One of these impacts relates to the method of accounting for the 
results of joint-ventures, which are now recognized using the equity method of accounting instead of the 
proportional  consolidation  method  we  used  prior  to  the  adoption  of  the  IFRS  11.   See  note  4.1  to  our 
financial statements for a description of these standards and their impact on our financial statements.  

Net operating revenues 

Net operating revenues increased by R$578.0 million, or 5.4%, to R$11,315.6 million in 2013 from 

R$10,737.6 million in 2012. 

Net  operating  revenues  relating  to  water  services  increased  by  R$323.7  million,  or  7.1%,  to 

R$4,906.0 million in 2013 from R$4,582.3 million in 2012.  This increase was principally due to: 

•                     an average 2.6% increase in the volume of water invoiced in 2013; and 

•                     the effect of the 5.15% tariff increase in September 2012, 2.35% tariff adjustment in April 2013 

and 3.1% tariff adjustment in December 2013. 

Net  operating  revenues  relating  to  sewage  services  increased  by  R$274.0  million,  or  7.4%,  to 

R$3,964.9 million in 2013 from R$3,690.9 million in 2012.  This increase was principally due to: 

•                     an average 2.9% increase in the volume of sewage services invoiced in 2013; and 

•                     the effect of the 5.15% tariff increase in September 2012, 2.35% tariff adjustment in April 2013 

and 3.1% tariff adjustment in December 2013. 

Gross revenue from construction decreased by R$19.7 million, or 0,8%, to R$2,444.8 million in 2013 
from  R$2,464.5 million  in  2012.   See  Note  3.3(b) to  our  financial  statements  as  of  December 31,  2013 
and 2012 and for the years ended December 31, 2013, 2012 and 2011 for a description of the accounting 
policies applicable to our construction services business.  

Cost of Sales and Services 

The cost of sales and services increased by R$366.4 million, or 5.7%, to R$6,816.3 million in 2013 
from  R$6,449.9 million  in  2012.   As  a  percentage  of  net  operating  revenues,  cost  of  sales  and  services 
increased to 60.2% in 2013 from 60.1% in 2012. 

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

•                     an increase of R$147.3 million or 11.7%, in salaries and related charges due to the following 
factors:  (i)  an  increase  of  6.17%  in  salaries  since  May  2012  and  8.0%   since  May  2013 
associated  to  the  implementation  of  the  Company’s  new  job  and  salary  plan,  which  had  an 
impact of approximately R$109.3 million; and (ii) the increase in the provision for pension plan 
expenses, amounting to R$22.1 million, due to changes in actuarial assumptions; 

79 

  
   
  
  
 
•                     an increase of R$95.2 million in depreciation and amortization, due to the increase in operating 

intangible assets in 2013, arising mainly from input of the works in operation; 

•                      an  increase  of  R$63.2  million  or  35.6%  in  expenses  related  to  water-treatment  materials, 
mainly due to increased consumption and the substitution of water-treatment products in order to 
meet increased demand while maintaining the same efficiency levels in water treatment; 

•                     an increase of R$62.0 million in costs of outsourced services, mainly due to: (i) preventive and 
corrective  sewage  system  maintenance  in  the  amount  of  R$17.7  million;  (ii)  environmental 
compensation  with  the  beach  recovery  service  in  the  amount  of  R$9.4  million;  (iii)  expenses 
related to consulting, advisory, and specialized services, which amounted to R$9.3 million; (iv) 
preventive and corrective maintenance in the water sewage operating systems in the amount of 
R$9.2 million; and (v) services provided for conservation of property and operating facilities in 
the amount of R$5.9 million , due to increase in areas being monitored; and 

•                      an  increase  of  R$21.2  million  payable  incurred  on  expropriations,  mainly  to  honor  the 

commitments assumed with the municipality of Paraguaçu Paulista. 

These  increases  were  partially  offset  by  a  decrease  of  R$36.5  million,  in  the  cost  of  electricity, 
mainly due to the decrease in the Tariff for the Use of Distribution System (TUSD), as a consequence of 
Provisional Presidential Decree 579/12 and Law 12,783/13.  

Gross Profit 

As  a  result  of  the  factors  discussed  above,  gross  profit  for  the  year  ended  December 31,  2013 
increased  by  R$211.6  million,  or  4.9%,  from  R$4,287.7 million  in  2012  to  R$4,499.3  in  2013.   As  a 
percentage of net operating revenues, gross profit decreased to 39.8% in 2013 from 39.9% in 2012. 

Selling Expenses  

Selling  expenses  decreased  by  R$60.2  million,  or  8.6%,  to  R$637.1  million  in  2013  from 
R$697.3 million in 2012.  As a percentage of net operating revenues, selling expenses decreased to 5.6% 
in 2013 from 6.49% in 2012. 

The decrease in selling expenses was principally due to the account receivables allowance for losses, 

due to the higher recovery of amounts in 2013, under installment agreements. 

This decrease was partially offset by an increase of R$18.7 million in salaries and related charges, 
due to the 6.17% in salaries since May 2012 and 8.0%  since May 2013 associated to the implementation 
of the Company’s new job and salary plan, which had an impact of approximately R$12.5 million. 

Administrative Expenses 

Administrative  expenses  increased  by  R$11.7  million,  or  1.6%,  to  R$729.1  in  2013  from 
R$717.4 million in 2012.  As a percentage of net operating revenues, administrative expenses decreased 
to 6.4% in 2013 from 6.7% in 2012. 

The increase in administrative expenses was principally due to the following factors: 

•                     an increase of R$34.6 million in amortization costs of software in 2013; 

•                     an increase of R$22.2 million in salaries and related charges due to the following factors: (i) an 
increase  of  6.17%  in  salaries  since  May  2012  and  8.0%   since  May  2013  associated  with  the 
implementation  of  the  Company’s  new  job  and  salary  plan,  which  had  an  impact  of 
approximately  R$7.8  million;  and  (ii)  the  increase  in  the  provision  for  pension  plan  expenses, 
amounting to R$13.5 million, due to changes in actuarial assumptions; 

80 

  
   
  
 
•                     an increase  in tax expenses of R$7.3 million, or 12.0% due to: (i) regulatory tax to ARSESP in 
the  amount  of  R$4.3  million;  and  (ii)  R$1.0  million  in  income  tax  on  remittances  abroad  as  a 
result of the local currency depreciation in 2013. 

The increase was partially offset by the following: 

•                     a decrease of R$28.9 million, or 19.9% mainly on services provided by third parties relating to 

advertising campaigns,  in the amount of R$29.4 million; 

•                      a  decrease  of  R$25.3  million  in  general  expenses,  mainly  due  to  the  expenses  on  judicial 

proceedings in the amount of R$14.2 million.  

Other Operating Income (Expenses), Net  

Other operating income (expenses), net, decreased by R$35.4 million, or 119.2%, to R$5.7 million 
income in 2013 from R$29.7 million expense in 2012.  Other operating expenses showed a decrease of 
R$37.5, or 40.9%, mainly due to the provision for losses for the indemnification of assets related to the 
concession for the municipality of Diadema, in the amount of R$60.3 million in 2012.  The decrease was 
partially offset by the asset write-offs related to asset obsolescence, in the amount of R$17.8 million in 
2013. 

Financial income (expenses), net 

Financial  income  (expenses),  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. 

Financial  income  (expenses),  net  increased  by  R$187.5  million,  or  63.4%,  to  a  R$483.2  million 
expense  in  2013  from  a  R$295.7 million  expense  in  2012.   As  a  percentage  of  net  operating  revenues, 
financial income (expenses), net increased to 4.3% in 2013 from 2.80% in 2012. 

The increase in financial income (expenses), net was principally due to:  

•                     an increase in foreign exchange losses related to loans and financing of R$217.3 million as a 
result  of  the  14.6%  depreciation  of  the  real  against  the  U.S.  dollar  in  2013,  compared  to  a 
depreciation of 8.9% of the real against the U.S. dollar in 2012; 

•                      an  increase  of  R$38.1  million  in  expenses  with  inflation  adjustment  on  loans  and  internal 
financings, mainly relating to the seventeenth and eighteenth debentures issued in February and 
December 2013, respectively. 

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

•                      an  increase  of  R$34.3  million  in  finance  income,  mainly  due  to  the  investment  of  interest 
earned  on  installment  payment  plans,  and  to  the  interest  on  the  seventeenth  and  eighteenth 
debentures issued; and 

•                     a decrease of R$10.0 million interest expenses on local loans and financing, mainly due to the 
repayment of the debt to Banco do Brasil in 2013, in the of R$380.7 million, associated to the 
change  in  debt  (issue  of  the  seventeenth  debenture  in  February  2013  and  anticipation  of  the 
amortization of the 11th debenture balance). 

Profit before income tax and social contribution 

As a result of the factors discussed above, profit before income tax and social contribution increased 
by 4.2%, to R$2,655.6 million in 2013 from R$2,547.6 million in 2012.  As a percentage of net operating 

  
   
  
revenues, our profit before income tax and social contribution decreased to 23.5% in 2013 from 23.7% in 
2012. 

81 

 
Income Tax and Social Contribution 

Income  tax  and  social  contribution  increased  by  R$96.3  million,  or  15.1%,  to  R$732.0  million  in 
2013  from  R$635.7 million  in  2012.   This  increase  was  principally  due  to  a  higher  taxable  income  in 
2013. 

Net Income for the year 

As a result of the factors discussed above, net income increased to R$1,923.6 million in 2013 from 
R$1,911.9 million  in  2012.   As  a  percentage  of  net  operating  revenues,  our  net  income  decreased  to 
17.0% in 2013 from 17.8% in 2012. 

Year Ended December 31, 2012 Compared to Year Ended December 31, 2011 

Net operating revenues 

Net operating revenues increased by R$810.2 million, or 8.2%, to R$10,737.6 million in 2012 from 

R$9,927.4 million in 2011. 

Net  operating  revenues  relating  to  water  services  increased  by  R$309.2 million,  or  7.2%,  to 

R$4,582.3 million in 2012 from R$4,273.1 million in 2011.  This increase was principally due to: 

•                     an average 2.4% increase in the volume of water invoiced in 2012; and  

•                      the  effect  of  the  6.83%  tariff  increase  in  September 2011,  and  the  5.15%  tariff  increase  in 

September 2012. 

Net  operating  revenues  relating  to  sewage  services  increased  by  R$261.2,  or  7.6%,  to 

R$3,690.9 million in 2012 from R$3,429.7 million in 2011.  This increase was principally due to: 

•                     an average 3.2% increase in the volume of sewage services invoiced in 2012; and  

•                      the  effect  of  the  6.83%  tariff  increase  in  September 2011,  and  the  5.15%  tariff  increase  in 

September 2012. 

Gross  revenue  from  construction  increased  by  R$239.9 million,  or  10.8%,  to  R$2,464.5 million  in 
2012 from R$2,224.6 million in 2011.  See Note 3.3 (b) to our financial statements as of December 31, 
2012  and  2011  and  for  the  years  ended  December 31,  2012,  2011  and  2010  for  a  description  of  the 
accounting policies applicable to our construction services business.  

Cost of Sales and Services 

The cost of sales and services increased by R$431.2 million, or 7.2%, to R$6,449.9 million in 2012 
from  R$6,018.7 million  in  2011.   As  a  percentage  of  net  operating  revenues,  cost  of  sales  and  services 
decreased to 60.1% in 2012 from 60.6% in 2011. 

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

•                      an  increase  in  construction  costs  of  R$237.5 million,  or  10.9%,  compared  with  the  previous 

year.  Such change was mainly due to higher investment in 2012; 

•                      an  increase  of  R$92.6 million,  or  8.2%,  in  salaries  and  related  charges  due  to  the  following 
factors:   (i) an  increase  of  6.17%  in  salaries  since  May 2012,  resulting  in  an  increase  of 
approximately  R$88.7 million;  and  (ii) an  increase  in  the  provision  we  made  for  termination 
benefits,  in  the  amount  of  R$17.2 million,  due  to  a  higher  number  of  employees  requesting 
retirement  and  the  adoption  of  a  new  law,  which  increased  the  required  notice  from  30  to 
90 days in cases of dismissal without cause.  These increases were partially offset by a decrease 

  
   
  
  
in  the  actual  cost  with  respect  to  the  actuarial  calculation  in  2012  related  to  our  defined 
contribution plan in the amount of R$12.5 million;  

82 

 
•                      an  increase  of  R$56.3 million,  or  8.4%,  in  costs  of  outsourced  services,  mainly  due  to:  
(i) vehicle rentals in the amount of R$22.9 million;  (ii) the R$17.0 million increase in the Alto 
Tietê PPP due to the initiation of operations in September 2011; (iii) services of maintenance and 
repositioning  of  pavement  in  the  amount  of  R$13.7 million,  as  part  of  intensified  efforts  to 
prevent  water  losses;  (iv) expenses  related  to  the  security  of  our  assets  in  the  amount  of 
$14.9 million, due to increases in equipment purchases and areas being monitored; and (v) water 
and  sewage  systems  maintenance,  which  amounted  to  R$5.9 million.   The  increase  in  costs  of 
outsourced  services  was  partially  offset  by  a  decrease  of  R$19.7 million  related  to 
socio-environmental programs established pursuant to an agreement with the municipality of São 
Paulo; 

•                      an  increase  of  R$31.5 million,  or  8.5%,  in  general  expenses,  mainly  due  to:   (i) the 
R$22.1 million provision pursuant to our service agreement with the municipality of São Paulo 
and (ii) beginning in February 2012, charges for water usage in the Baixada Santista reservoir, 
amounting to R$6.9 million; 

•                     an increase of R$22.7 million, or 14.7%, in water-treatment expenses, mainly due to increased 
consumption and the substitution of water-treatment products in order to meet increased demand 
while maintaining the same efficiency levels in water treatment; 

•                      an  increase  of  R$21.9 million,  or  14.9%,  in  maintenance  expenses,  mainly  due  to:  
(i) preventive  and  corrective  maintenance  of  the  water  and  sewage  operation  systems  in  the 
amount of R$8.7 million and (ii) maintenance of water and sewage network connections in the 
amount of R$7.2 million; and 

•                     an increase of R$5.8 million, or 1%, in the cost of electricity due to increased consumption and 
higher energy tariffs.  This increased consumption and increase in tariffs was partially offset by a 
discount of 15%, on the fees for usage of distribution systems related to basic sanitation applied 
since September 2011. 

These increases were partially offset by a decrease of R$24.0 million, or 3.2%, in depreciation and 
amortization  expenses,  which  decreased  from  R$739.0 million  to  R$715.1 million,  mainly  due  to  the 
revision in the amortization criteria occurred in 2011 of intangible assets in connection with our service 
agreement with the municipality of São Paulo. 

Gross Profit 

As  a  result  of  the  factors  discussed  above,  gross  profit  for  the  year  ended  December 31,  2012 
increased by R$379.0 million, or 9.7%, from R$3,908.7 million in 2011 to R$4,287.7 million in 2012.  As 
a percentage of net operating revenues, gross profit increased to 39.9% in 2012 from 39.4% in 2011. 

Selling Expenses  

Selling  expenses  increased  by  R$78.0 million,  or  12.6%,  to  R$697.3 million  in  2012  from 
R$619.3 million in 2011.  As a percentage of net operating revenues, selling expenses increased to 6.49% 
in 2012 from 6.2% in 2011. 

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

•                     an increase of R$72.0 million, or 59.9%, from R$120.3 million in 2011 to R$192.2 million in 
2012, mainly due to account receivables allowance for losses.  This increase was due mainly to 
additional  provisions  of  R$14.4 million  related  to  private  clients,  R$8.8 million  related  to 
municipal entities and R$35.1 million related to state entities; 

•                     an increase of R$3.5 million or 1.7%, in expenses related to outsourced services mainly due to 
new  billing  technology  related  to  the  reading  of  usage,  issuance  of  bills  and  delivering  bills, 
which  cost  approximately  R$11.3 million,  in  addition  to  an  increase  in  the  number  of 
connections and inflation adjustments of the contracts in the metropolitan region of São Paulo.  

  
   
  
This  increase  was  partially  offset  by:   a  decrease  of  R$4.5 million  resulting  from  reduced 
services provided related to the implementation of the Rationed Water Use Program (“Programa 
de Uso Racional da Água” or “PURA”) in city schools; and 

•                     an increase of R$4.0 million, or 2.1%, in personnel salaries and related charges as a result of:  a 
6.17%  salary  readjustments  as  of  May 2011,  which  had  an  impact  of  approximately 
R$2.7 million. 

83 

 
Administrative Expenses 

Administrative  expenses  increased  by  R$33.8 million,  or  4.9%,  to  R$717.4 million  in  2012  from 
R$683.6 million in 2011.  As a percentage of net operating revenues, administrative expenses decreased 
to 6.7% in 2012 from 6.9% in 2011. 

The increase in administrative expenses was principally due to the following factors: 

•                     an increase in outsorced service expenses in the amount of R$22.2 million, or 18.0%, mainly 
on  services  provided  by  third  parties  relating  to:   (i) advertising  campaigns  focused  on  socio-
environmental  programs,  in  the  amount  of  R$16.7 million  and  (ii) engagement  of  consultants 
and specialized service providers, in the amount of R$5.6 million; 

•                     an increase in tax expenses in the amount of R$6.8 million, or 11.1%, due to:  (i) R$3.7 million 

in property taxes and (ii) regulatory tax to ARSESP in the amount of R$3.2 million. 

The decrease was partially offset by the following: 

•                     a decrease of R$6.7 million, or 30.3%, in amortization costs of software in 2012. 

Other Operating Income (Expenses), Net  

Other  operating  income  (expenses),  net,  decreased  by  R$64.1 million,  or  68.3%,  to  R$29.7 million 
expense in 2012 from R$93.8 million expense in 2011.  Other operating expenses showed a decrease of 
R$67.1 million, or 74.3%, mainly due to:  (i) provision for losses related to an indemnificatory liability 
related to the concession for the municipality of Mauá in the amount of R$85.9 million in 2011, (ii) asset 
write-offs in 2011 related to asset obsolescence, in the amount of R$35.3 million, and (iii) write-offs in 
2011 relating to studies and projects that were not economically viable in the amount of R$6.1 million.  
These decreases were partly offset by the provision for losses for the indemnification of assets related to 
the concession for the municipality of Diadema, in the amount of R$60.3 million in 2012. 

Financial income (expenses), net 

Financial  income  (expenses),  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. 

Financial  income  (expenses),  net  decreased  by  R$337.3 million,  or  53.3%,  to  a  R$295.7 million 
expense in 2012 from a R$633.0 million expense in 2011.  As a percentage of net revenues from sales and 
services, financial income (expenses), net decreased to 2.8% in 2012 from 6.4% in 2011. 

The decrease in financial income (expenses), net was principally due to:  

•                     a decrease in foreign exchange loss related to loans and financing of R$331.8 million as a result 
of the 8.9% depreciation of the real against the U.S. dollar in 2012, compared to a depreciation 
of 12.6% of the real against the U.S. dollar in 2011, and the 2.4% appreciation of the real against 
the Japanese Yen in 2012, compared to a depreciation of 18.6% of the real against the Japanese 
Yen in 2011;  

•                     a decrease of R$48.7 million in interest expenses mainly due to the amortization of our eighth, 

ninth and thirteenth debentures in June and October 2011, and February 2012, respectively;  

•                      a  decrease  of  R$46.4 million  in  expenses  relating  to  judicial  proceedings  mostly  involving 

clients; and 

•                      a  decrease  of  R$34.8 million  in  inflation  adjustments,  mainly  relating  to  our  contracts  with 

municipalities. 

  
   
  
The decrease in financial income (expenses), net was partially offset by: 

84 

 
•                     a decrease in interest rates related to our cash positions, in the amount of R$108.9 million, or 

40.1%; and 

•                     a decrease of R$22.8 million in the inflation adjustments, mainly due to amounts received as a 
result  of  the  concession  of  the  exclusive  rights  concerning  the  deposit  of  salaries  of  our 
employees in 2011. 

Profit before income tax and social contribution 

As a result of the factors discussed above, profit before income tax and social contribution increased 
by  35.6%,  to  R$2,547.6 million  in  2012  from  R$1,879.0 million  in  2011.   As  a  percentage  of  net 
operating revenues, our profit before income tax and social contribution increased to 23.7% in 2012 from 
18.9% in 2011. 

Income Tax and Social Contribution 

Income  taxes  increased  by  R$137.6 million,  or  27.6%,  to  R$635.7 million  in  2012  from 

R$498.1 million in 2011.  This increase was principally due to a higher taxable income in 2012. 

Net Income for the year 

As a result of the factors discussed above, net income increased to R$1,911.9 million in 2012 from 
R$1,380.9 million in 2011.  As a percentage of net operating revenues, our net income increased to 17.8% 
in 2012 from 13.9% in 2011. 

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, long-term borrowings from Brazilian federal governmental financial institutions, 
and long-term financing from multilateral organizations and from domestic and international development 
banks, and also from capital markets.  As of December 31, 2013, we had R$1,782.0 million of cash and 
cash equivalents.  The outstanding current portion of our long-term indebtedness was R$641.0 million as 
of  December 31,  2013,  of  which  R$216.0  million  was  denominated  in  foreign  currency.   Long-term 
indebtedness was R$8,809.1 million as of December 31, 2013, of which R$3,482.6 million consisted of 
foreign  currency-denominated  obligations.   We  believe  that  we  have  sufficient  sources  of  liquidity  and 
capital  to  meet  our  liquidity  and  capital  requirements  for  the  next  few  years,  in  light  of  our  current 
financial position and our expected cash generated by operating activities. 

Cash Flow 

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$2,777.2  million,  R$2,343.2 million  and  R$2,698.6 million  in  2013,  2012  and  2011, 
respectively.   The  main  driver  of  our  cash  flow  from  operating  activities  relates  to  our  strong  revenue 
stream, which is due to the nature of our business and to the fact that we are expanding our infrastructure. 

Cash Used in Investing Activities 

Our  cash  used  in  investing  activities  was  R$2,281.5  million,  R$1,996.7  million  and  R$1,883.2 
million in 2013, 2012 and 2011, respectively. The main driver of our cash flow from investing activities 
relates  to  the  purchases  of  intangibles  assets,  as  required  under  our  concession  and  program  contracts, 
which is due to the fact that we are expanding our infrastructure and service coverage. 

Cash Used in Financing Activities 

  
   
  
Our cash used in financing activities was R$629.7 million, R$572.7 million and R$661.3 million in 
2013, 2012 and 2011, respectively. The main driver of our cash flow from financing activities relates to 
the  proceeds  and  repayments  of  loans  used  to  finance  purchases  of  intangible  assets  related  to  our 
concession and program contracts, in order to support the expansion of our services and our payment of 
interest on shareholders’ equity.

Indebtedness Financing 

Our total financial indebtedness increased by 6.5%, from R$ R$8,875.3 million as of December 31, 
2012  to  R$9,450.1  million  as  of  December 31,  2013.   In  addition,  during  the  same  period,  our  total 
foreign  denominated  indebtedness  recorded  increased  by  15.0%,  from  R$3,215.8  million  as  of 
December 31, 2012 to R$3,698.6 million as of December 31, 2013.   

As  of  December 31,  2013,  we  had  R$8,809.1  million  in  long-term  indebtedness  outstanding 
(excluding  the  current  portion  of  long-term  indebtedness),  of  which  R$3,482.6  million  consisted  of 
foreign  currency-denominated  long-term  debt.   We  had  an  outstanding  current  portion  of  long-term 
indebtedness of R$640.9 million as of December 31, 2013.  As of December 31, 2013, R$216.0 million 
of  this  current  portion  of  long-term  indebtedness  was  denominated  in  foreign  currency.   As  of 
December 1,  2013,  our  Standard  &  Poor’s  Rating  Service  domestic  rating  was  brAA+  and  our  S&P 
international rating was BB+. Since July 2013 we also started to be covered by Moody’s America Latina 
Ltda, by whom our national rating was Aa1.br and our global rating was Baa3.   

Various  contractual  agreements  we  have  entered  into,  including  certain  financing  agreements  with 
Caixa  Econômica  Federal  and  BNDES,  provide  for  liens  over  a  portion  of  our  cash  flows  from 
operations.  In addition to Caixa Econômica Federal and 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, 2013, 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$2,234.5 million.

Refering to our foreign currency-denominated indebtedness, the amount of R$2,766.1 million, net of 
transaction costs, as of December 31, 2013 was denominated in U.S. dollars.  This indebtedness consisted 
principally of: 

•                      R$1,108.1 million  (US$475.7  million)  in  U.S.  dollar  denominated  loans  contracted  with  the 
Inter-American Development Bank, or the IADB, composed of the following:  (i) two loans to 
finance the first phase of the Tietê Project in 1992 and one loan to finance the second phase in 
2000,  under  which  payments  of  principal  are  made  in  semiannual  installments  with  final 
maturity in December 2016, December 2017 and July 2025.  The principal amount of this loan is 
adjusted semiannually for the variation of the U.S. dollar, and accrues interest at a rate varying 
from  1.14%  to  3.00%  plus  LIBOR;  (ii) credit  agreement  executed  in  September 2010  with  the 
IADB  for  the  financing  of  the  third  phase  of  the  Tietê  Project.   This  loan  matures  on 
September 3, 2035.  Amortizations will be made in semiannual installments after a grace period 
of  six  years.   The  principal  amount  accrues  interest  at  USD  LIBOR.   We  have  pledged  as 
collateral part of our receivables from our sales and services up to the amount due; 

•                      R$87.1 million  (US$37.3  million)  in  U.S. dollar  denominated  loans  contracted  with  the 
International  Bank  for  Reconstruction  Development  -  IBRD  which  was  entered  into  on 
October 28,  2009,  amounting  to  US$100.0 million,  for  the  financing  of  the  Water  Source 
Program  (Programa  Mananciais).   The  loan  matures  in  March 2034.   Amortizations  will  be  in 

  
   
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
semi-annual  installments  starting  in  September 2019.   The  principal  amount  accrues  interest  at 
the USD LIBOR plus a variable spread; 

 87 

 
•                      R$415.1 million  (US$178.2  million)  in  U.S.  dollar  denominated  loans  from  the  AB  Loan 
financing  contracted  with  the  IADB  in  May 2008.   Under  this  loan,  payments  of  principal  are 
made in annual installments with final maturity in May 2023.  The principal amount is adjusted 
semiannually  for  the  LIBOR  plus  spread  and  accrued  interest  at  a  rate  varying  from  2.49%  to 
2.99%.  This loan was used to repay an outstanding series of debt securities in connection with 
the implementation of our investment plan;  

•                      R$1,141.3 million  (US$490.0  million)  in  U.S.  dollar  denominated  Eurobonds  issued  in 
November 2006  (US$140.0 million  with  an  interest  rate  of  7.5%)  and  in  December 2010

Our  borrowings  from  multilateral  institutions  and  with  Government  Agency,  such  as  the  IADB, 
IBRD and JICA, 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, IBRD and JICA; we have granted a guarantee (contra garantia) to the federal government.  
For further information on the terms of these loan agreements, see “Item 7.B. Related Party Transactions 
– Government Guarantees of Financing.” 

Our  outstanding  domestic  debt  was  R$5,751.5  million  as  of  December 31,  2013  and  consisted

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 2014 and 2015, we start to pay the rental of 
the infrastructure (in 240 installments) and the lease is updated accordingly to the contract.  On 
August 31,  2013,  SES  Campo  Limpo  Paulista  and  Várzea  Paulista  started  operations,  and  the 
corresponding amount as of December 31, 2013 was of R$144,384 million.   

Under BNDES program, in the amount of R$826.1 million, we issued 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 third series will mature in November 2020 and 
the  second  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%  per  year,  such  excess  will  be  added  to  the  principal  amount.   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.   This  issuance  was  entirely  subscribed  by  BNDES.   In 
February 2011,  we  issued  our  fourteenth  debentures,  the  second  tranche  out  of  those  three,  also 
subscribed exclusively by BNDES.  These debentures are divided in three series:  the first and third series 
will mature in February 2022 and the second, in March 2022.  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%  per  year,  such  excess  will  be  added  to  the 
principal  amount.   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  9.20%  per  year.   In  October  2013,  we

in October 2024 and the second, in November 2024.  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%

interest at the rate of the IPCA index plus 8.26% per year.  In December 2013, BNDES subscribed to the 
debentures of the first and second series.  BNDES will subscribe to the debentures of the third series in 
2015.  We have used the funds raised from the three issuances 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.

Additionally,  in  June 2010,  we  issued  500,000  debentures  to  the  FGTS,  based  on  the  FGTS’s 
program  to  finance  companies  in  the  sanitation,  transport  and  real  estate  businesses  (our  twelfth 
issuance).   The  debentures  bear  interest  based  on  the  TR  plus  9.5%  per  year  and  will  mature  in 
June 2025.  The debentures bear a grace period of four years in respect of payments, and we may redeem 
the debentures starting in July 2014.  We used the proceeds from the twelfth issuance to fund a portion of 
our capital expenditure program in the water supply and sewage system.  

In August 2011,  the joint-controlled  entity  “Aquapolo”  issued  326,732 debentures, registered  as  its 
first issuance of simple debentures, nonconvertible, in a single 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.  
The proceeds from the first issuance were used to build the Aquapolo plant and infrastructure designed to 
treat industrial water from this petrochemical industrial center in Mauá municipality.  

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  were  used  to 
repay  financial  commitments  throughout  2012,  including  the  early  redemption  of  our  thirteenth 
debentures issuance.  

In  November 2012,  we  carried  out  our  sixteenth  debentures  issuance  of  R$500 million,  with  a 
maturity date of November 2015 and bearing interest, each quarter with an interest rate of between 0.30% 
and 0.7% per year plus the CDI rate.  These proceeds of this issuance were used to pay the Company’s 
financial commitments for 2012 and 2013.  

In January 2013, we carried out our seventeenth debentures issuance of R$1.0 billion in three series, 
the  first for  R$424.7 million  with  maturity  date of  January 2018  and with  an  interest rate  of 0.75% per 
year  plus  the  CDI  rate,  the  second  for  R$395.2 million  with  a  maturity  of  January 2020  and  with  the 
interest rate of 4.50% per year plus IPCA variation and the third for R$180.1 million with a maturity date 
of January 2023 and with an interest rate of 4.75% per year plus IPCA variation.  The proceeds of these 
issuances were used to pay our financial commitments for 2013  

In March 2013 we made the first and second series amortization payments and the early redemption 
of the remaining balance of the 1st series of the eleventh debenture issuance.  This issuance was due to 
mature in March 2015.

Part  of  our  real-denominated  indebtedness  is  indexed  to  take  into  account  the  effects  of  inflation.  
This debt provides for inflation-based increases to the principal amount, determined by reference to the 
IPCA. 

Financial Covenants 

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

indebtedness. 

Foreign currency denominated indebtedness 

With respect to our indebtedness denominated in U.S. dollars, 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 financial 
covenants  related  to  loan  agreements  713,  896  and  1212  consider  -  Tariffs  must:   (a) produce  revenues 
sufficient to cover the system’s operating expenses, including administrative, operating, maintenance, and 
depreciation expenses; (b) provide a return on the balance sheet value of property, plant, and equipment 
not less than 7%; and (c) during project execution, the balances of short-term loans must not exceed 8.5% 
of total equity.  These agreements have a cross default clause with IADB.  The financial covenants related 
to AB Loan agreements (1983AB) consider the Company’s ratio of debt service coverage, which must be 
higher than or equal to 2.35:1.00; and the total adjusted debt over EBITDA, determined on a consolidated 
basis,  which  must  be  lower  than  or  equal  to  3.65:1.00.   This  agreement  has  a  cross  default  clause.  See 
Note 15 of our Financial Statements. 

The indentures relating to our US$ 140.0 million 7.5% notes due 2016 and US$ 350.0 million 6.25% 
notes due 2020 prohibit, 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 indentures) is greater 
than 3.65:1.00:  or (ii) the Debt Service Coverage Ratio (as defined in the related indentures) is less than 
2.35:1.00.   This  agreement  has  a  cross  default  clause,  i.e.  the  early  maturity  of  any  debt  in  connection 
with our loans or the loans of any of our subsidiaries in a total principal amount of US$25.0 million or 
more (or the corresponding amount in other currencies) shall imply this agreement’s early maturity.  See 
Note 15 of our Financial Statements. 

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  require  us  to  maintain  (i) adjusted  EBITDA/Adjusted  net 
operating revenues equal to or higher than 38%, (ii) adjusted EBITDA/adjusted financial expenses equal 
to or higher than 2.35:1.00; and (iii) adjusted net debt/adjusted EBITDA equal to or lower than 3.65:1.00. 

In  addition,  all  of  our  financing  agreements  with  the  Caixa  Econômica  Federal  and  most  of  our 
financing  agreements  with  BNDES  are  subject  to  a  Performance  Improvement  Agreement  (Acordo  de 
Melhoria de Desempenho).  The Performance Improvement Agreement, dated May 28, 2007, as amended 
in  August 2012,  was  entered  into  between  us  and  the  federal  government,  and  the  Caixa  Econômica 
Federal and BNDES as intervening parties.  Pursuant to this agreement, we were required to comply with 
at least four of eight financial and operating ratios stipulated for the period 2012 to 2016.  If we fail to 
comply with any of the ratios required by the Caixa Econômica Federal and BNDES, either 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  if  needed.   On  March  14,  2013,  the 
Ministry  of  Cities  revoked  Normative  Instruction  05  of  2008,  which  regulated  the  Agreement  on 
Performance Improvement (Acordo de Melhoria de Desempenho), or API.  According to the Instruction, 
the APIs executed by March 14, 2013 will remain valid until their respective expiration dates, and it is not 
necessary to execute or reschedule APIs for new contracts.  

  
   
  
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.  The agreement 
with Caixa Econômica Federal has a cross default clause.  See Note 15 of our Financial Statements. 

91 

 
With respect to our outstanding debentures, the twelfth issuance requires us to maintain an adjusted 
current  ratio  (current  assets  divided  by  current  liabilities,  excluding  from  current  liabilities  the  current 
portion of noncurrent debts incurred by the Company that are recorded in current liabilities) higher than 
1.0:1.0 and an EBITDA/financial expenses ratio equal to or higher than 1.5:1.0.  This issuance has a cross 
default clause.  See Note 15 of our Financial Statements. 

The tenth, fourteenth and eighteenth issuances require us to maintain (i) Adjusted EBITDA/Adjusted 
net operating revenues equal to or higher than 38%, (ii) Adjusted EBITDA/Adjusted financial expenses 
equal  to  or  higher  than  2.35:1.0,  and  (iii)  Adjusted  net  debt/Adjusted  EBITDA  equal  to  or  lower  than 
3.65:1.0.  These issuances have a cross default clause.  See Note 15 of our Financial Statements.  

The  fifteenth,  sixteenth  and  seventeenth  issuances  require  us  to  maintain  (i) an  EBITDA/paid 
financial expenses ratio equal to or higher than 1.5:1.0, and (ii) an adjusted total debt/EBITDA ratio equal 
to  or  lower  than  3.65:1.0.   These  issuances  have  a  cross  default  clause.   See  Note  15  of  our  Financial 
Statements.

As  of  December 31,  2013  and  2012,  we  had  met  all  the  requirements  set  forth  by  its  loan  and 

financing agreements. 

Capital Requirements 

We  have,  and  expect  to  continue  having,  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 2013, we recorded 
R$2.7  billion  to  improve  and  expand  our  water  and  sewage  system  and  to  protect  our  water  source  in 
order  to  meet  the  growing  demand  for  water  and  sewage  services  in  the  State  of  São  Paulo.  We  have 
budgeted investments in the amount of approximately R$12.8 billion from 2014 through 2018.  See “Item 
4.A. History and Development of the Company –Capital Expenditure Program.”

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  declared  dividends  of  R$537.5  million,  R$534.3 million  and 
R$578.7 million  in  2013,  2012  and  2011,  respectively.   See  “Item 7.B.  Related  Party  Transactions—
Dividends.” 

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 2013, 2012 and 2011, we invested 
R$6.4 million, R$6.3 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 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)  to  develop  and  support  research  projects  involving 
researchers from graduate schools, the State of São Paulo and our employees.  This partnership provides 
R$50 million in incentives, to be paid equally by each of the two institutions.  Under this partnership, 12 
projects  have  been  approved  and  nine  of  them  are  currently  underway.   They  are  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.   

In  May  2013,  we  launched  a  second  phase  of  our  agreement  with  the  São  Paulo  Research 
Foundation.  In this second phase, the seven lines of research were defined in greater detail in order to 
precisely contemplate our needs.  In this phase, 37 proposals were submitted, and the São Paulo Research 
Foundation is currently analyzing these proposals with respect to their scientific and technical merits. 

We  have  been  seeking  financing  for  the  project  “Sabesp  –  Technological  Innovations  for  the 
Sanitation Sector” from the Brazilian Agency for Innovation – FINEP. The program “FINEP Innovates 
Brazil” aims at supporting Brazilian companies’ plans for strategic investment in innovation. These plans 
must  detail  a  company’s  targets  and  goals  for  the  period  during  which  they  will  receive  financing, 
pursuant  to  the  Federal  Government’s  “Greater  Brazil  Plan  –  PBM.”   Our  project  is  valued  at 
approximately R$ 90 million. This project consists of five parts as follows: (i) vacuum collection system 
and  sewage  removal;  (ii)  production  system  for  reused  water  in  urban  and  industrial  uses;  (iii) 
biofiltration units for odor control; (iv) sludge dryer based on solar radiation for sewage treatment stations 
–  Franca  Sewage  Treatment  Station;  and  (v)  plasma  gasification  system  for  solid  waste  from  sewage 
treatment plants.  

We  also  started  a  partnership  with  Fraunhofer  Institute  in  Germany  em  2011,  in  order  to  obtain 
biomethane  from  the  sewage  treatment  process  to  be  used  as  fuel  for  cars.   In  the  second  semester  of 
2014,  it  will  start  to  fill  up  a  fleet  of  49  cars,  instead  of  gasoline,  as  a  3-year  test.   This  project  will 
contribute  to  reduce  pollutant  emission  into  the  atmosphere.   We  are  investing  R$900  thousand  in  this 
system while our German partner is investing R$5.1 million.

Seeking  energy  efficiency  in  our  operations,  we  projected  an  equipment  to  calculate  the  correct 
oxygen dosage to be used in air diffusors, which are used in the sewage treatment process.  The project 
aims also to find the best cleaning period and when these devices have to be replaced. 

Additionally,  we  have  developed  custom  made  biofilters  to  reduce  the  odor  from  sewage  pumping 

stations and sewage treatment plants. 

D.      Trend Information  

Several factors may affect our future results of operations, liquidity and capital resources, including: 

•                     the interests of our controlling shareholder; 

•                     regulations  issued by  ARSESP regarding  several  aspects  of our business, with  respect  to our 
ability  to  adjust  our  tariffs  and  the  competency  of  state  and  municipalities  to  manage  their 
sanitation affairs; 

•                     Brazilian economic conditions; 

•                     meteorological conditions; 

•                      the  effects  of  any  continued  international  financial  turmoil  that  may  affect  liquidity  in  the 

Brazilian capital and lending markets; 

•                     the effects that further changes in the Basic Sanitation Law and its interpretation may have on 

the basic sanitation industry in Brazil and on us; 

•                     the effects of inflation in our results of operations; 

•                      the  effects  of  fluctuations  in  the  value  of  the  Brazilian  real   and  in  interest  rates  on  our  net 

interest income; 

•                     the effects of the tariff revision conducted by ARSESP;  

•                     the renewal of our concession agreements;  

•                     the impacts on our business of the water consumption reduction incentive program and of any 
other  measures we may need to take until the level of our reservoirs is normalized and sufficient 
to supply the customers in the São Paulo metropolitan region; 

•                     decisions by the São Paulo State Department of Water and Energy (DAEE) and the National 
Water  Agency  (ANA)  limiting  the  volume  of  water  that  may  be  drawn  from  the  Cantareira 
System, the water system we use to serve the São Paulo Metropolitan Region, and the measures 
that we may be required to take to ensure the provision of water to our customers; and 

•                     the formalization of agreements with certain of the municipalities we serve. 

Each  of  these  factors  is  described  in  more  detail  under  “5.A.  Operating  and  Financial  Review  and 

Prospects.” 

In addition, you should read “3.D. Risk Factors” for a discussion of the risks we face in our business 

operations, which could affect our business, results of operations or financial condition.

______________ 

(1)   Estimated interest payments on loans and financing were determined considering the interest rates as of December 31, 2013.  
However,  our  loans  and  financing  are  subject  to  variable  interest  indexation  and  foreign  exchange  fluctuations,  and  these 
estimated  interest  payments  may  differ  significantly  from  payments  actually  made.  The  debt  agreements  have  cross  default 
clauses. 

(2)    Includes  capital  lease  obligations  which  are  collateralized  by  part  of  the  billings  from  the  provision  of  water  and  sewage 

services. 

(3)     The  purchase  obligations  are  the  contractual  obligations  of  investments  and  expenses  and  consider  the  estimated  inflation 

adjustments for each year. 

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, 2013, see Note 15 to our financial statements as of December 31, 2013 and 2012 and for 
the years ended December 31 2013, 2012, 2011 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  eight  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 elect the majority 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, including holders of 
ADSs.” 

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  a  renewable  two-year  term.  
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  Law  No.  6,404  of 
December  15,  1976,  as  amended  (“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. 

95 

 
Six  of  the  current  members  of  our  board  of  directors,  Dilma  Seli  Pena,  Walter  Tesch,  Alberto 
Goldman,  Jerônimo  Antunes,  Reinaldo  Guerreiro  and  Alexander  Bialer  were  elected  at  the  general 
shareholders’ meeting held on April 23, 2012.  The directors Claudia Polto da Cunha and Francisco Vidal 
Luna  were  elected  at  the  general  shareholders’  meeting  held  on  April 22,  2013.  The  tenure  of  all  the 
directors will end upon the election of members for the new term at the general shareholders’ meeting to 
be  held  on  April 30,  2014.   Currently,  we  have  four  directors  considered  independent  under  the  Novo 
Mercado rules. 

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

Profit Sharing and Pension Plans 

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$18.4 million, R$7.4 million and R$8.9 million in 2013, 2012 
and 2011, respectively.  Based on independent actuarial reports, as of December 31, 2013, our obligation 
under these plans totaled R$2,327.0 million.  For further information on our pension plans see Note 19 to 
our financial statements as of December 31, 2013 and 2012 and for the years ended December 31, 2013, 
2012 and 2011 included elsewhere in this annual report. 

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$68.5 million, R$60.5 million and R$56.6 million in 2013, 

2012, 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  a 
renewable two-year term.  Our next general shareholders’ meeting will be held on April 30, 2014.  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 
directors for a renewable two-year term.  Meetings of our board of executive officers are held weekly in 
the  case  of  ordinary  meetings  or  when  called  by  the  chief  executive  officer  in  the  case  of  special  or 
extraordinary  meetings.   See  “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. 

Fiscal Committee (Conselho Fiscal) 

Our fiscal committee, which is established on a permanent basis, consists of a minimum of three and 
a maximum of five members and generally meets once a month.  Our fiscal committee currently consists 
of four members and four alternates.  Furthermore, each member has its respective alternate.  The current 
members of our fiscal committee were elected in the shareholders’ meeting held on April 22, 2013.  Their 
tenure  will  end  on  April  30,  2014.   The  primary  responsibility  of  the  fiscal  committee,  which  is 
independent from management and from the external auditors appointed by our board of directors, is to 
review our financial statements and report on them to our shareholders.

Audit Committee

The members are appointed by the board of directors. 

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

The  minimum  availability  required  from  each  member  of  the  audit  committee  is  thirty  hours  per 
month.   Under  our  bylaws,  the  members  shall  exercise  their  roles  for  the  same  period  as  their 
corresponding  term  of  office,  or  until  otherwise  resolved  by  the  general  shareholders’  meeting  or  by 
resolution of the board of directors. All of our Audit Committee members are independent.

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 (i) the Union of Workers in Water, Sewage and Environment of São Paulo - 
SINTAEMA,  (ii) workers  union  of  Santos  Urban  Industries,  Baixada  Santista  region,  South  Coast  and 
Vale Ribeira - SINTIUS, (iii) the Union of Engineers of the State of São Paulo - SEESP, (iv) the Union of 
Attorneys of the State of São Paulo - SASP and (v) the Union of Industrial Technicians of the State of 
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,  among  other  requests,  to 
increase (i) wages by 1.5%, (ii) the salary base over which the annual profit distribution is calculated, (iii) 
the payment of overtime from 50% to 100% ; and (iv) additional payment of working night hours from 
20% to 50%.  The Labor Court decided in favor of the unions, and we appealed the decision. Our appeal 
resulted  in  a  definitive  decision on  the  matter,  issued  by  the  court  on  August  17,  2012,  suspending  the 
unions’ requests, except for the increase in the additional payment of overtime from 20% to 50%.   

  
   
  
  
  
  
  
  
  
  
  
 
  
 103 

 
In 2011, we entered into an additional collective bargaining agreement, which:  (i) increased wages 
by  8.00%  (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  meal  vouchers  by 
10.07%, and (iv) increased all other benefits by 8.00%, among other provisions.   

The collective agreement entered into in 2012 resulted in the following: (i) an increase in salaries by 
6.17% (which corresponds to the inflation adjustment for the period plus further addition 1.93%), (ii) the 
establishment of an employment guarantee for 98% of our employees, (iii) an increase in meal vouchers 
of 10% and a further increase of 8% in all other benefits, and (iv) an end to extra payments to employees 
who drive company vehicles.  

Our last collective bargaining agreement, executed in 2013, resulted in: (i) a salary increase of 8% 
(which  corresponds  to  the  inflation  adjustment  for  the  period  plus  a  real  gain  of  2.5%),  (ii)  the 
establishment of an employment guarantee for 98% of our employees, (iii) an increase of 13.6% in meal 
vouchers (vale refeição), and (iv) an increase of 21.5% in food allowance and an additional of 15% for 
employees who work on flexible work shifts, among other things. 

We  have  experienced  the  following  strikes  in  the  last  seven  years,  none  of  which  interrupted  the 
essential  services  that  we  provide:  a  four-day  strike  in  June 2008,  a  three-day  strike  in  May 2009,  an 
eight-day strike in 2010, a one-day strike in 2011 and a two-day strike in 2013.  In 2007 and 2012 there 
were  no  strikes.   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  16,  2014,  the  members  of  the  board  of  directors  and  the  executive  officers  owned  an 
aggregate of 1,515 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

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 
owned  5.0% or  more  of  our  common  shares  and  for  our  officers  and  directors,  individually  and  as  a

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. 

Rendering 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.   Gross  revenue  from  sales  to  the  State, 
including State entities, totaled R$449.1 million in 2013, R$431.0 million in 2012 and R$405.0 million in 
2011.   Our  accounts  receivable  from  the  State  for  water  supply  and  sewage  services  totaled  R$63.9 
million and R$65.5 million, as of December 31, 2013 and 2012, respectively.  In addition, as required by 
law, we invest our cash and cash equivalents with government financial institutions. 

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 2013, 2012 and 2011, we made payments to former employees of R$140.1 million, 
R$132.7 million  and  R$124.4 million,  respectively, 
in  respect  of  Plan  G0.   The  State  made 
reimbursements  in  2013,  2012  and  2011  in  the  amount  of  R$111.0  million,  R$104.4 million  and 
R$89.5 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: 

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

•                     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;  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. 

105 

 
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. This amount was updated until September 2008 according to ICPA index and amounted 
to R$696.3 million. 

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.  We have 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 
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. 

  
   
  
the  outstanding  balance  of  dividends 

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  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 

106 

 
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 
performed,  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 
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,  2013,  the  Disputed  Reimbursement  Amount, 
plus the reservoirs mentioned above, amounted to R$1,412.5 million, but due to the uncertainty regarding 
the recovery of the amount our management decided not to recognize the reimbursements.  See Note 9 to 
our financial statements as of December 31, 2013 and 2012 and for the year ended December 31, 2013, 
2012 and 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.   

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. 

 107 

  
   
  
 
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  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, 2013, we had made a provision of R$1,780.3 million in our pension obligations accounts in 
respect of the pension benefit obligation of Plan G0. 

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  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 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  the  State  and  the  City  of  São  Paulo  executed  an  agreement  in  the  form  of  a 
convênio,  to  which  we  and  ARSESP  consented,  under  which  they  agreed  to  manage  the  planning  and 
investment for the basic sanitation system of the city of São Paulo on a joint basis.  The principal terms of 
this convênio  were as follows: 

•       The  State  and  the  City  of São  Paulo would  execute  a  separate  agreement  with us,  granting  us 

exclusive rights to provide water and sewage services in the city of São Paulo. 

•      ARSESP would regulate and oversee our activities regarding water and sewage services in the 

city of São Paulo, including tariffs. 

•      A management committee (Comitê Gestor) would be responsible for planning water and sewage 
services for the city and for reviewing our investment plans.  The management committee consists of six 
members  appointed  for  two-year  terms.   The  State  and  the  City  of  São  Paulo  have  the  right  to  appoint 
three members each.  We may participate in management committee meetings but may not vote. 

In  application  of  the  convênio,  we  executed  a  separate  contract  with  the  State  and  the  city  of  São 
Paulo,  also  dated  June 23,  2010,  to  regulate  the provision of  these  services  for  the  following  30  years.  
The principal terms of this contract are as follows: 

  
   
  
•       The  total  investment  stated  in  the  contract  must  be  equal  to  13%  of  gross  revenues  from  the 
provision  of  services  to  the  city  of  São  Paulo,  net  of  the  taxes  on  revenues,  which  total  approximately 
R$600 million per year. 

108 

 
•       We  must  transfer  7.5%  of  the  gross  revenues  we  derive  under  the  convênio,  and  subtract 
(i) COFINS and PASEP taxes, and (ii) unpaid bills of publicly owned properties in the city of São Paulo, 
to the Municipal Fund for Environmental Sanitation and Infrastructure (Fundo Municipal de Saneamento 
Ambiental  e  Infraestrutura),   established  by  Municipal  Law  No. 14,934/2009.   In  April  2013,  ARSESP 
postponed  the  application  of  such  municipal  charges  until  the  conclusion  of  the  tariff  revision  process, 
based  on  a  request  from  the  São  Paulo  State  Government  to  analyze,  among  other  things,  methods  to 
reduce the impact on consumers. 

•      Our investment plan must be compatible with the sanitation plans of the State, the City of São 

Paulo and, if necessary, the Metropolitan region. 

•      ARSESP will ensure that the tariffs will adequately compensate us for the services we provide 
and that tariffs may be adjusted in order to restore the original balance between each party’s obligations 
and economic gain (equilíbrio econômico financeiro). 

We  currently  have  an  investment  plan  in  place  that  reflects  these  obligations  and  addresses  their 
compatibility  with  the  sanitation  plans  of  the  State,  the  City  of  São  Paulo  and,  if  necessary,  the 
Metropolitan  region.   The  investment  plan  is  not  irrevocable  and  will  be  reviewed  by  our  management 
committee every four years, particularly with respect to the investments to be executed in the subsequent 
period. 

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. 

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,  on  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$100.5 million as of December 31, 2013.

Capital Sources—Indebtedness Financing.”

Use of Reservoirs 

We currently use the Guarapiranga and Billings reservoirs, which are also used by another company 
controlled by the São Paulo State Government, 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  8,000  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  has  a  fixed  target  for  reduction  or  maintenance  of  water  consumption, 
according to technical evaluations carried out by us. 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 2013, 2012 and 2011 amounted to R$12.9 million, 
R$12.3 million and R$10.9 million, respectively. 

The expenses related to personnel assigned by other entities to us totaled R$1.0 million in both 2013 

and 2012; in 2011, none of our personnel had been assigned by other offices.  

Services Obtained from State Government Entities 

As of December 31, 2013, 2012 and 2011, we had an outstanding amount payable of R$2.0 million, 
R$1.0 million  and  R$12.1 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  DAEE.   Such  non-operating  assets  totaled  R$1.0  million, 

R$1.0 million and R$2.3 million as of December 31, 2013, 2012 and 2011, respectively. 

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  São  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  São  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 São Paulo 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$8.4  million,  R$7.4 million  and  R$8.9 million  in  2013,  2012  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. 

110 

 
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 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. In September 2012, the judge presiding over 
the  case  ordered  a  financial  expert  inspection.   An  expert  was  appointed  in  early  2013  but  has  not  yet 
begun an inspection.  

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$3.6  million,  R$3.4 million  and  R$2.8 million  in  2013,  2012  and 
2011,  respectively,  and  it  refers  to  salaries  and  other  short-term  benefits  management.   An  additional 
R$0.6 million, R$0.7 million and R$1.1 million related to the bonus program was accrued in 2013, 2012 
and 2011. 

For further information on management compensation, see “Item 6.B. Compensation.” 

Loan agreement through credit facility 

We hold interests in some companies.  Although we do not hold the majority of shares in any of the 
companies  in  which  we  hold  interests,  we  are  party  to  shareholders’  agreements  which  provide  for  the 
power of veto with regard to certain management proposals and decisions.  Due our significant influence 
on  these  companies  by way of  shareholders’  agreements,  for  accounting purposes,  these  companies  are 
accounted for by applying the equity method of accounting.  

We entered into a loan agreement through credit facility with the Águas de Andradina S.A., Águas de 
Castilho S.A., and Aquapolo Ambiental S.A. to finance the operations of these companies, until the loans 
and financing required to banks are cleared.  

          The  contracts  signed on  January  19, 2012  with Águas  de Andradina  and  Águas  de  Castilho were 
settled  in  July  2012,  according  to  the  agreement’s  provisions.  On  July  18,  2012,  new  agreements  were 
signed  with  both  companies,  pursuant  to  the  terms  and  conditions  in  the  table  below.  The  agreement 
signed  with  Aquapolo  Ambiental  on  March  30,  2012  remains  with  the  same  features,  according  to  the 
table below:

A.      Financial Statements and Other Financial Information 

See “Item 3.A. Selected Financial Data” and “Item 18.  Financial Statements.” 

Legal Proceedings 

We  are  currently  subject  to  numerous  legal  proceedings  relating  to  civil,  tax,  labor,  corporate  and 
environmental issues arising in the normal course of our business. Several individual disputes account for 
a significant part of the total amount of claims against us. Our audited financial statements only include 
provisions for probable and reasonably estimable losses and expenses we may incur in connection with 
pending  proceedings.  Our  material  legal  proceedings  are  described  in  Note  18  to  our  audited  financial 
statements  included  in  this  annual  report,  and  that  description  is  incorporated  by  reference  under  this 
Item. 

Civil Public Actions Related to Environmental Matters  

We  are  subject  to  administrative  and  judicial  proceedings,  including  proceedings  initiated  by  the 
company  of  Environmental  Sanitation  Technology  (Companhia  de  Technologia  de  Saneamento 
Ambiental  –  Cetesb),  Public  Prosecutor  of  the  State  of  São  Paulo  and  non-governmental  organizations 
among  others.   These  result  from  proceedings  alleged  environmental  damage  including  proceedings: 
 (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  certain  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.   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. We classify certain of these proceedings as 
probable loss and possible loss. As of December 31, 2013 we have provisioned R$182.7 million for such 
matters. 

Other Legal Proceedings 

The  Civil  Entity  Coordination  Committee  of  Piracicaba  filed  a  civil  public  action  against  us,  the 
National Water Agency and the State of São Paulo Treasury Department seeking, among other claims for 
relief:  (i)  the  termination  of  use  of  31  m3/s  of  water  from  one  of  the  municipality’s  reservoirs;  (ii)  the 
creation  of  a  schedule  to  regulate  water  use  and  withdrawal  from  the  Piracicaba  water  basin  by the 
Cantareira system to eliminate possible damage to populations downstream and (iii) the development of 
an  environmental  impact  study  on  the  Cantareira  system  evaluating  the  impact  of  water  use  and 

  
   
  
  
  
withdrawal  on  the  various  basins  that  constitute  the  system.  This  civil  public  action  was  decided 
favorably  for  us  in  two  lower  courts,  and  the  plaintiff’s  appeal  to  a  higher  court  seeking  special  and 
extraordinary recourse was denied based on inadmissibility. We are currently awaiting a court decision on 
the  appeal  brought  by  the  plaintiff  against  this  decision.  The  amount  involved  in  this  proceeding  as  of 
December 31, 2013 is R$19.2 billion. We have assessed the risk of loss as remote, and accordingly have 
not taken any provisions.  

 112 

 
The Public Prosecutor’s Office of the State of São Paulo filed a civil public action against us seeking: 
(i)  the  nullification  of  the  contract  we  entered  with  the  Municipality  of  São  Paulo  on  June  23,  2010 
regarding  the  service  of  water  supply  and  sewage  services;  (ii)  our  exclusion  from  BM&F  Bovespa’s 
Corporate  Sustainability  Index;  and  (iii)  sewage  treatment  coverage  of  the  entire  Municipality  of  São 
Paulo  by  2018.   The  plaintiff’s  request  for  an  injunction  was  denied,  and  the  courts  maintained  this 
decision  after  we  presented  our  defense.   Separately,  we  have  challenged  the  amount  claimed  by  the 
Public Prosecutor’s Office of the State of São Paulo in these proceedings. The amount involved in these 
proceedings is R$12.3 billion as of December 31, 2013. We have assessed the risk of loss as remote, and 
accordingly have not taken any provisions. 

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 half of the net profit as increased or reduced by: 

a)    the amount intended to form the legal reserve; and 

b)    the amount intended to form the reserves for contingencies and any written-off amounts of the 

same reserves formed in previous fiscal years. 

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,  2013,  2012  and  2011  the 
balance  of  our  legal  reserve  was  R$713.0  million,  R$616.8 million  and  R$521.2 million,  respectively, 
which was equal to 11.5%, 9.9% and 8.4%, 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. 10,303  of 
October 31,  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 
shareholders  vote  to  transfer  all  or  a  portion  of  the  reserve  to  capital  or  retained  earnings.   As  of 
investment  reserve  of  R$5,980.5  million, 
December 31,  2013,  2012  and  2011  we  had  an 
R$4,690.6 million and R$3,408.6 million, respectively. 

113 

  
   
  
 
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 our financial statements prepared in accordance with Brazilian 
GAAP. 

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. 

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 
U.S. dollars  to  be  delivered  to  the  depositary  for  distribution  to  holders  of  ADSs.   See  “Item 10.D. 
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.” 

114 

 
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 amount of tax-deductible interest that may be paid is calculated by applying the daily pro 
rata variation of the government’s long-term interest rate (TJLP) on the shareholders’ equity during the 
relevant period and cannot exceed the greater of:   

•                      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 

•                     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 low tax jurisdiction (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  the  mandatory  dividends  distributable  amount  as  prescribed  in  Brazilian  Corporate 
Law. 

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, 2013 correspond to the minimum established by law of 25.0% of the net 
income  and  the  difference  of  R$537.5  million  will  be  recorded  in  2014  after  the  general  shareholders’ 
meeting. 

Distributions of dividends 

The  following  table  sets  forth  the  distributions  of  dividends  that  we  made  to  our  shareholders  in 
respect of our 2013, 2012 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.  
Within the context of our tax planning, we may in the future continue to determine that it is in our best 
interest to distribute interest on shareholders’ equity.

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, 2013, we had 5,645 registered holders of common shares. 

On April 30, 2007, our shareholders approved a reverse stock split of 125 common shares into one 
common share.  Following a ratio change effected on January 24, 2013, each American Depositary Share 
currently  represents  one  of  our  common  shares.   On  April 22,  2013  our  shareholders  approved  a  stock 
split,  following  which  each  common  share  represented  three  new  common  shares.   IFRS  requires  the 
retrospective application 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

Market Price of ADSs 

Our ADSs, each of which represents one of our common shares, as of the date of this annual report, 
are listed on the NYSE under the symbol “SBS.”  Prior to June 8, 2007, each ADS represented 250 of our 
common  shares.   From  that  date  through  January 23,  2013,  each  ADS  represented  two  of  our  common 
shares.   Following  a  ratio  change  effected  on  January 24,  2013,  each  American  Depositary  Share 
currently  represents  one  of  our  common  shares.   On  April 22,  2013  our  shareholders  approved  a  stock 
split,  following  which  each  common  share  represented  three  new  common  shares.  Our  ADSs  began 
trading on the NYSE on May 10, 2002 in connection with the initial offering of our equity securities in 
the United States.

C.      Markets  

Trading on the Brazilian Stock Exchange 

The preferred shares and common shares are traded on the BM&FBovespa, the only Brazilian stock 
exchange  that trades shares. Trading  on  the  BM&FBovespa  is  limited  to brokerage firms  and  a  limited 
number  of  authorized  entities.  The  CVM  and  BM&FBovespa  have  discretionary  authority  to  suspend 
trading in shares of a particular issuer under certain circumstances. 

Trading on the BM&FBOVESPA is conducted between 10:00 a.m. and 5:00 p.m. or from 11:00 a.m. 
to 6:00 p.m. (during daylight savings time in Brazil).  The BM&FBOVESPA also permits trading from 
5:30 p.m. to 6:00 p.m. or from 6:30 p.m. to 7:00 p.m. (during daylight savings time in Brazil) during a 
different  trading  period  called  the  “after  market.”   Trading  during  aftermarket  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 (i) for a period of 30 
minutes whenever the index of this stock exchange falls more than 10% from the index registered for the 
previous  day;  (ii) for  one  hour  if  the  index  of  this  stock  exchange  falls  15%  or  more  from  the  index 
registered for the previous day, after the reopening of trading; and (iii) for a certain period of time to be 
defined  by  the  BM&FBovespa,  if  the  index  of  this  stock  exchange  falls  20%  or  more  from  the  index 
registered  for  the  previous  day,  after  the  reopening  of  trading.   The  minimum  and  maximum  price  is 
based  on  a  reference  price  for  each  asset,  which  will  be  the  previous  session’s  closing  quote,  when 
considering the asset at the beginning of the day before the first trade, or the price of the day’s first trade. 
The asset’s reference price will be altered during the session if there is an auction sparked by the intraday 
limit being breached. In this case the reference price will become whatever results from the auction.  

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. 

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 
2013,  the  BM&FBOVESPA  had  a  total  market  capitalization  of  approximately  US$1,030.57  billion 
(R$2,414.22 billion) and an average daily trading volume of US$3,459.5 million (R$7,417,745 million).  
The  top  ten  stocks  in  terms  of  2013  trading  volume  accounted  for  approximately  41.31%  of  all  shares 
traded on the BM&FBOVESPA as of December 31, 2013.  As of December 31, 2013, we accounted for 
approximately 0.75% 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, 
June 19, 2006, and April 23, 2012, 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: 

•                     maintain only voting shares; 

•                      hold  public  offerings  of  shares  in  a  manner  favoring  diversification  of  the  company’s 

shareholder base and broader access to retail investors; 

•                      maintain  a  minimum  free  float  of  at  least  25.0%  of  the  outstanding  capital  stock  of  the 

company; 

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

company; 

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

•                     ensure that at least 20.0% of the members of the board of directors are independent, as defined 

under the Novo Mercado regulation; 

•                      prepare  annual  financial  statements,  including  cash  flow  statements,  in  compliance  with 

U.S. GAAP or IFRS or reconciled from Brazilian GAAP to U.S. GAAP or IFRS; 

•                      disclose  information  on  a  quarterly  basis,  including  share  ownership  of  certain  of  our 

employees and directors and amount of free float of shares; 

•                     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 

•                     make greater disclosure of related party transactions. 

On  May 10,  2011,  the  Novo  Mercado  rules  were  revised  and  currently  establish  the  following 

additional obligations:  

•                     the chairman of the board of directors is prohibited from simultaneously holding the position of 

chief executive officer; 

•                     the board of directors must disclose its opinion on takeover proposals within 15 days from the 

presentation of the proposal; and 

•                     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. 

120 

 
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 
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. 

121 

  
   
  
  
 
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  our 
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  executive  officers  must  be  a 

resident in Brazil.  Our bylaws do not establish any mandatory retirement age limit. 

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

Description of Common Shares 

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.  Financial  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. 

122 

 
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: 

•                     the right to participate in the distribution of profits; 

•                      the  right  to  participate  equally  and  ratably  in  any  remaining  residual  assets  in  the  event  of 

liquidation of the company; 

•                      the  right  to  supervise  the  management  of  the  corporate  business  as  specified  in  Brazilian 

Corporate Law; 

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

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

Pursuant to Brazilian Corporate Law and our 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: 

•                     staggered terms for directors; 

•                     cumulative voting, except as described below; or  

•                     measures that could prevent a takeover attempt. 

However, under the laws of the State of São Paulo, 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.   

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: 

•                     to reduce the mandatory distribution of dividends; 

•                      to  merge  into  another  company  or  to  consolidate  with  another  company,  subject  to  the 

conditions set forth in Brazilian Corporate Law; 

•                     to participate in a centralized group of companies, as defined under Brazilian Corporate Law 

and subject to the conditions set forth therein; 

•                     to change our corporate purpose; 

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

•                     creating preferred shares or increasing an existing class of preferred shares without maintaining 
the existing ratio with the remaining class of preferred shares, unless when already set forth in or 
authorized by the bylaws; 

•                     to transform into another type of company; 

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

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

Corporate Law. 

The right of withdrawal lapses 30 days after publication of the minutes of the shareholders’ meeting 
that approved 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  stock 
merger 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. 

124 

  
   
  
 
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. 

Special and General Meetings 

Unlike  the  laws  governing  corporations  incorporated  under  the  laws  of  the  State  of  Delaware,  the 
Brazilian corporate 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  corporate  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  shall  be  called,  convened  and  deliberated  under  Brazilian 
Corporate Law to address all matters of interest to the Company. 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, and the first call should be made at least 15 days 
prior to the meeting. In our case, the first call is made 30 days in advance due the issuance of ADRs, as 
recommended by the CVM. The second call should be made at least 8 days in advance, if quorum is not 
reached, pursuant to the Brazilian Corporate Law.” 

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  corporate  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. 

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: 

•                     election and dismissal of the members of our board of directors and our fiscal committee, if the 

shareholders have requested the setup of the latter; 

•                     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; 

•                     amendment of our bylaws; 

•                     approval of our merger, consolidation or spin-off; 

•                     approval of our dissolution or liquidation, as well as the election and dismissal of liquidators 

and the approval of their accounts; 

•                     granting stock awards and approval of stock splits or reverse stock splits; 

•                      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; 

  
   
  
  
125 

 
•                     authorization to delist from the Novo Mercado and to become a private company, except if the 
cancellation is due to a breach of the Novo Mercado 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 

•                     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. 

Equal Treatment 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. 

Reserves 

General 

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, 2013, 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, 2013, we had an investment reserve of R$5,980.5 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, 2013, the balance 
of our legal reserve was R$713.0 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. 

    126 

 
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. 

CMN  Resolution  No. 1,927  of  May  18,  1992,  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 of CMN Resolution No. 1,289 of March 20, 1987 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  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. 

127 

  
   
  
 
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. 

For the purposes of calculating the income tax and the social contribution related to 2010 and 2009, 
we  opted  to  adopt  the  Transition  Tax  Regime,  or  RTT,  which  allows  us  to  eliminate  the  accounting 
effects of Law No. 11,638/07 and Provisional Measure No. 449/08, converted into Law No. 11,941/09, by 
the  records  in  the  fiscal  books  –  LALUR  and  auxiliary  controls,  without  any  modification  to 
bookkeeping.  

We have followed the same tax practices since 2008, as RTT became mandatory and will remain in 
effect  until  legislation  ruling  on  the  tax  effect  of  new  accounting  methods  and  seeking  tax  neutrality 
comes into effect. 

On November 11, 2013, Provisional Measure No. 627 as enacted, altering the federal tax laws on the 
Corporate Income Tax (IRPJ), Social Contribution on Net Income (CSLL), PIS/PASEP Contribution and 
Contribution of Social Security Financing (Cofins).  This Provisional Measure revokes RTT, which had 
been enacted by Law No. 11,941/09, and provides for the taxation of legal entities domiciled in Brazil, 
referring  to  the  equity  addition  deriving  from  the  profit  sharing  earned  abroad  by  subsidiaries  and 
associated companies and profit earned by individuals residing in Brazil by means of foreign subsidiary.  
This Provisional Measure allows for the possibility of adopting its effects in the 2014 calendar year. 

We  prepared  a  study  of  potential  effects  of  applying  Provisional  Measure  No.  627/2013  and 
Normative Ruling 1,397/2013 and concluded that they do not result in relevant effects on our operations 
and financial statements for the fiscal year ended December 31, 2013, based on the best interpretation of 
current  wording  of  the  Provisional  Measure.   The  eventual  conversion  of  Provisional  Measure  No. 
627/2013 into law may alter our conclusions if the final text encompasses changes not envisioned by and 
alters current taxation to which we are subject.  We await the conversion of this Provisional Measure into 
law, so that we may decide on its early adoption or not, as per final wording to be enacted.  

Taxation of Gains 

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 a non-Brazilian holder to a resident or person domiciled in 
Brazil.   This  is  due  to  the  fact  that  the  common  shares  can  be  considered  assets  located  in  Brazil  for 
purposes of Law No. 10,833. 

Thus,  gains,  for  purposes  of  taxation  of  gains  earned  in  a  sale  or  disposition  of  common  shares 
carried  out  on  a  Brazilian  stock  exchange  (which  includes  transactions  carried  out  on  the  organized 
over-the-counter market): 

•                     are exempt from income tax when assessed on a non-Brazilian holder that (1) has registered its 
investment in Brazil with the Central Bank under the rules of CMN Resolution No. 2,689/00, or 
2,689 Holder, and (2) is not a resident of or domiciled in a Nil or Low Taxation Jurisdiction; or  

•                     in all other cases, including gains realized by a Non-Resident Holder that is not a 2,689 Holder 
and/or is a resident of or domiciled in a Nil or Low Taxation Jurisdiction, subject to income tax 
at a 15.0% rate. In these cases, a withholding income tax at a rate of 0.005% will be applied and 
can later 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  at  a  rate  of  15%,  except  for  Nil  or  Low  Taxation 
Jurisdiction, which, in this case, would be 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. 

 128 

 
For  Brazilian  purposes,  as  of  January 2009,  a  Nil  or  Low  Taxation  Jurisdiction  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. See “—Discussion on Low or Nil Taxation Jurisdictions.” 

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. 

Sale of ADSs by non-Brazilian holder to another non-Brazilian holder 

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. 

In  case  the  argument  above  does  not  prevail  the  gain  on  disposition  of  ADSs  by  a  non-Brazilian 
holder to a resident in Brazil or even to a non-Brazilian resident 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. 

Exchange of ADSs for common shares 

Although  there  is  no  clear  regulatory  guidance,  the  withdrawal  of  ADSs  in  exchange  for  common 
shares is not subject to Brazilian income tax provided that the regulatory rules are appropriately observed 
in respect to the registration of the investment before the Central Bank of Brazil.   

Upon receipt of the underlying common shares in exchange for ADSs, non-Brazilian holders may also 
elect to register with the Central Bank the U.S. dollar amount of such preferred shares or common shares 
as a foreign portfolio investment under Resolution No. 2689/00 or as a foreign direct investment under 
Law 4,131/62. 
Exchange of common shares for ADSs 

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  Nil  or  Low  Taxation 
Jurisdiction, 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.

Discussion on Low or Nil Taxation Jurisdictions 

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 which: (i) 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. 

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 with respect to 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  Nil  or  Low   Taxation  Jurisdiction  holder.   Such  payments,  subject  to  certain  limitations  and 
requirements, are deductible for Brazilian income tax purposes. This interest is limited to the daily pro 
rata  variation  of  the  Federal  Government’s  long-term  interest  rate,  as  determined  by  the  Central  Bank 
from time to time, and cannot exceed the greater of: 

(a)     50% of net income (after the social contribution on net profits and before the provision for 
corporate income tax, and the amounts attributable to shareholders as interest on net equity) 
for the period with respect to which the payment is made; or 

(b)     50% of the sum of retained earnings and earnings reserves as of the date of the beginning of 

the period with respect to which the payment is made. 

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 foreign exchange transactions (“IOF/Exchange”) 

Pursuant to Decree No. 6,306, dated December 14, 2007, as amended, or Decree No. 6,306/07, the 
conversion  of  Brazilian  currency  into  foreign  currency  (e.g.,  for  purposes  of  paying  dividends  and 
interest)  and  the  conversion  of  foreign  currency  into  Brazilian  currency  may  be  subject  to  the  Tax  on 
Foreign Exchange Transactions or IOF/Exchange. Currently, for most exchange transactions, the rate of 
IOF/Exchange  is  0.38%.  Effective  as  of  December  1,  2011,  currency  exchange  transactions  carried  out 
for the inflow of funds in Brazil for investments made by a foreign investor (including a Non-Resident 
Holder, as applicable) are subject to IOF/Exchange at a 0% rate in case of variable income transactions 

  
   
  
  
carried out on the Brazilian stock, futures and commodities exchanges, as well as in the acquisitions of 
shares of Brazilian publicly held companies in public offerings or subscription of shares related to capital 
contributions, provided that the company has registered its shares for trading on the stock exchange. The 
IOF/Exchange  rate  will  also  be  0%  for  the  outflow  of  funds  from  Brazil  related  to  these  types  of 
investments, including payments of dividends and interest on shareholders’ equity and the repatriation of 
funds invested in the Brazilian market. 

 130 

 
The Brazilian government may increase the rate of the IOF/Exchange to a maximum of 25.0% of the 
amount  of  the  foreign  exchange  transaction  at  any  time,  but  such  an  increase  would  not  apply 
retroactively. 

Tax on transactions involving bonds and securities (“IOF/Bonds Tax”) 

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.   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.  

U.S.  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: 

•                     an individual who is a citizen or resident of the United States; 

•                      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; 

•                     an estate the income of which is subject to U.S. federal income taxation regardless of its source; 

or 

•                     a trust if it (1) is subject to the primary supervision of a court within the United States and one 
or more 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, Medicare tax on net investment income, state, local 
or non-U.S. tax consequences of acquiring, holding or disposing of common shares or ADSs. 

131 

 
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 
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 Brazilian taxes that are withheld, 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  ADSs  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. 

132 

  
   
  
 
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,  if  a 
U.S. holder  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 
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.  

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,  including  in  order  to  comply 
with  additional  annual  filing  requirements  imposed  under  legislation  enacted  in  2010.   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  (currently  at  a  rate  of  28  percent)  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. 

133 

 
In addition, U.S. holders should be aware that additional reporting requirements apply 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  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  these  additional 
reporting requirements for foreign financial assets to their particular situation.

ITEM 11.         QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 
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 4.3 to our 
financial statements as of December 31, 2013 and 2012 and for the years ended December 31, 2013, 2012 
and 2011 included elsewhere in this annual report. 

Exchange Rate Risk 

As  of  December 31,  2013,  2012  and  2011,  R$3,698.6  million,  R$3,215.8 million  and 
R$3,053.4 million, or 39.1%, 36.2% and 36.2%, respectively, of our debt obligations were denominated 

  
   
  
  
  
in foreign currencies.  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. 

134 

 
Exchange Rate Sensitivity 

We  estimate  that  the  potential  loss  to  us  in  connection  with  U.S.  dollar  and  yen-denominated  debt 
that would have resulted as of December 31, 2013, 2012 and 2011 from each hypothetical instantaneous 
and unfavorable 1% change in the U.S. dollar and yen against the real  would have been approximately 
R$37.0  million,  R$32.3 million  and  R$30.7  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$369.9 million, R$323.1 million and R$306.7 million as of December 31, 2013, 
2012 and 2011, respectively. 

The fluctuation of the real in relation to the U.S. dollar and yen for the years ended December 31, 

2013, 2012 and 2011 were as follows:

We  have  not  utilized  derivative  financial  instruments  in  the  years  ended  December 31,  2013,  2012 

and 2011. 

As of December 31, 2013, 2012 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,  2013,  2012  and  2011,  R$1,653.9  million,  or  17.5%,  R$2,2029.7 million,  or 
22.9%, and R$2,364.1 million, or 28.1%, 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, 2013, 2012 and 2011, R$1,245.9 million, or 13.2%, R$1,835.9 million, or 
20.2%, 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,  2013,  2012  and  2011,  R$1,617.7  million, 
R$1,319.5 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,  2013,  2012  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$1,529.2 million, R$1,796.6 million 
and  R$2,027.0 million  as  of  December 31,  2013,  2012  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$94.5  million,  R$88.8 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, 2013, 
2012 and 2011, respectively, had occurred.  Consistent with these estimates, a hypothetical instantaneous 
and  unfavorable  1000  basis  points  change  in  these  interest  rates  would  have  resulted  in  losses  of 
approximately  R$945.0  million,  R$887.5 million  and  R$859.6 million  as  of  December 31,  2013,  2012 
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, as applicable, and that such movement may or may not affect interest 
rates applicable to any other homogenous category of financial liabilities. 

 135 

 
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, 2013.  For 
the foreign currency denominated obligations, these amounts have been converted at the selling rates as 
of December 31, 2013 and do not represent amounts which may actually be payable with respect to such 
obligations on the dates indicated.

D.      American Depositary Shares 

In the United States, our common shares trade in the form of ADS.  Following a ratio change effected 
on January 24, 2013, each ADS represents one common share of our company.  Following a stock split 
which  took  place  on  April 22,  2013,  we  issued  two  new  ADSs  for  each  ADS  currently  trading  and 
distributed  them  to  our  holders  on  April  29,  2013.  The  ADSs  are  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)

Cancellation of ADSs for the purpose of withdrawal, including 
if the deposit agreement terminates 

US$0.05 (or less) per ADS or portion thereof (to the extent not 
prohibited by the rules of any stock exchange on which the 
ADSs are listed for trading) 

For:

Issuance of ADSs, including issuances resulting from a 
distribution of common shares or rights or other property 

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 common 
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$0.05 (or less) per ADS or portion thereof per calendar year 
(in addition to the cash distribution fee of $0.02 per ADS that 
the depositary has collected during the year) 
Registration or transfer fees 

Cable, telex and facsimile transmissions expenses (when 
expressly provided in the deposit agreement) 

Expenses of the depositary in converting foreign currency to 
U.S. dollars 
Expenses of the depositary 

Depositary services

Transfer and registration of common shares on our common 
share register to or from the name of the depositary or its agent 
when you deposit or withdraw common shares 

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 

    137 

  
   
  
  
  
  
 
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 
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 2013 

From  January 1,  2013  to  December 31,  2013,  we  received  reimbursements  in  the  amount  of 
US$811,400  for  standard  out-of-pocket  maintenance  costs  for  the  ADRs,  any  applicable  performance 
indicators relating to the ADR facility, marketing 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 
defined in the United States Exchange Act Rule 13a-15(e), as of the year ended December 31, 2013. 

138 

  
   
  
  
 
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,  2013,  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. 

b) Management’s Report on Internal Control over Financial Reporting 

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  controls  over 

financial reporting.    

Our  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  applicable  generally  accepted  accounting  principles.   Our  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  our 
assets, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation 
of financial statements in accordance with applicable generally accepted accounting principles, and that 
our receipts and expenditures are being made only in accordance with authorizations of our management 
and  directors,  and  (3) provide  reasonable  assurance  regarding  prevention  or  timely  detection  of 
unauthorized acquisition, use, or disposition of our 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. 

Under the supervision and with the participation of our CEO and CFO, our management conducted 
an  assessment  of  our  internal  control  over  financial  reporting  as  of  December 31,  2013  based  on  the 
criteria established in “Internal Control —Integrated Framework” issued by COSO in 1992. 

As a result of the assessment described above, our management concluded that as of December 31, 
2013, we did maintain effective internal control over financial reporting based on the criteria established 
in “Internal Control — Integrated Framework” issued by COSO in 1992.  

Our 

independent  registered  public  accounting  firm,  Deloitte  Touche  Tohmatsu  Auditores 
Independentes,  has  issued  an  audit  report  on  the  effectiveness  of  our  internal  control  over  financial 
reporting.  That report is included below. 

c) Attestation Report of the Registered Public Accounting Firm 

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUTING FIRM ON INTERNAL  
CONTROL OVER FINANCIAL REPORTING  

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

We  have  audited  the  internal  control  over  financial  reporting  of  Companhia  de  Saneamento  Básico  do 
Estado de São Paulo - SABESP (the “Company”) as of December 31, 2013, based on criteria established 
in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations 
of  the  Treadway  Commission.   The  Company’s  management  is  responsible  for  maintaining  effective 
internal control over financial reporting and for its assessment of the effectiveness of internal control over 
financial  reporting,  included  in  the  accompanying  Management’s  Report  on  internal  control  over 

  
   
  
Financial Reporting.  Our responsibility is to express an opinion on the Company’s internal control over 
financial reporting based on our audit.  

 139 

  
  
 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight 
Board (United  States). Those  standards require  that  we plan  and perform  the  audit  to  obtain reasonable 
assurance about whether effective internal control over financial reporting was maintained in all material 
respects.  Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting, 
assessing  the  risk  that  a  material  weakness  exists,  testing  and  evaluating  the  design  and  operating 
effectiveness of internal control based on the assessed risk, and performing such other procedures as we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our 
opinion. 

A company’s internal control over financial reporting is a process designed by, or under the supervision 
of,  the  company’s  principal  executive  and  principal  financial  officers,  or  persons  performing  similar 
functions, and effected by the company’s board of directors, management, and other personnel to provide 
reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial 
statements for external purposes in accordance with International Financial Reporting Standards (IFRS), 
as issued by the International Accounting Standards Board   (IASB). A company’s internal control over 
financial reporting includes those policies and procedures that (1) pertain to the maintenance of records 
that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the 
company;  (2) provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit 
preparation of financial statements in accordance with International Financial Reporting Standards (IFRS) 
as issued by the International Accounting Standards Board (IASB), and that receipts and expenditures of 
the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements. 

Because of the inherent limitations of internal control over financial reporting, including the possibility of 
collusion or improper management override of controls, material misstatements due to error or fraud may 
not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of 
the internal control over financial reporting to future periods are subject to the risk that the controls may 
become inadequate because of changes in conditions, or that the degree of compliance with the policies or 
procedures may deteriorate. 

In our opinion, the Company maintained, in all material respects, effective internal control over financial 
reporting  as  of  December 31,  2013,  based  on  the  criteria  established  in  Internal  Control  -  Integrated 
Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight 
Board  (United  States),  the  financial  statements  as  of  and  for  the  year  ended  December 31,  2013  of  the 
Company  and  our  report  dated  April 25,  2014,  expressed  an  unqualified  opinion  on  those  financial 
statements and included explanatory paragraph related to the accompanying financial statements that have 
been retrospectively adjusted as a result of changes in accounting practices related to employee benefits 
and accounting for joint arrangements.

d) Changes in internal control over financial reporting 

There have been no changes in our internal control over financial reporting that occurred during the 
fiscal year ended December 31, 2013 that have materially affected, or are reasonably likely to materially 
affect, our internal control over financial reporting. 
ITEM 16.         [RESERVED]  

  
   
  
ITEM 16A.           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. 

140 

 
ITEM 16B.           CODE OF ETHICS  

We have adopted a code of business conduct and ethics, as defined in Item 16B of Form 20-F under 
the 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 head of 
accounting, as well as our suppliers and third-party contractors.  To ensure compliance with the Code of 
Ethics and Conduct, we have an Ethics Committee and an internal Whistle-blowing Channel, as well as a 
Corporate  Accountability  Procedure  and  an  Ombudsman  Office  as  well  as  a  Customer  Service  that 
receive external complaints.  The internal channel can receive anonymous whistle blowing.  The results of 
the investigations are forwarded to the Audit Committee.  Cases of recurrence are reported to the Ethics 
Committee,  which  urges  the  related  departments  to  develop  preventive  actions.   In  2013,  105  whistle 
blowings were recorded, 62% of which were verified and 38% are under investigation.  Out of the total, 
25%  refer  to  misconduct,  such  as  moral  harassment,  discrimination,  persecution  and  unfair  treatment. 
 During  2013,  25  of  our  employees  or  outsourced  employees  received  penalties  (5  warnings,  2 
suspensions  and  18  dismissals).   Our  Ethics  Committee  is  also  responsible  for  addressing  relevant 
inquiries and interpreting the norms of the Code of Ethics for all of our employees.  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

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 
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.

ITEM 16G.          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,  four  of  our  eight  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 seven 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. 

143 

  
   
  
 
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  four  members  and  four  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  Francisco  Vidal  Luna.   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.  

Risks Committee 

In  2009,  our  board  of  executive  officers  created  the  Risks  Committee  with  responsibilities  to:  i) 
evaluate the maximum amounts of risk that Management should incur in its operations in order to obtain 
planned results; ii) evaluate the identification, measurement, treatment and processing of risks in action 
plans;  iii)  forward  its  statements,  proposals  and  evaluations  to  the  audit  committee  and  to  the  board  of 
executive officers for review, as well as submit such statements, proposals and evaluations to the board of 
directors for approval.  The Risks Committee is coordinated by a chairman and consists of representatives 
from  the  following  management  divisions:  Corporate  Management;  Technology,  Enterprises  and 
Environment; Metropolitan; Economics and Finance and Investor Relations; and Regional Systems. 

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, 
the  chief  executive  officer’s 
evaluating 
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 
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. 

 144 

 
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. 

Citizens’ Access to Information at Sabesp   

The  federal  law  No.  12,527/11  (LAI),  regulated  by  State  Decree  No.  58.052/12,  determines  that 
bodies and entities of the Public Administration must create an unit to make available Citizen Information 
Services – SIC in order to serve and guide citizens, receive and manage information requests, as well as 
make available to the citizen information of his/her interest and the requirement to present the motives or 
reasons of request is forbidden.  

In order to comply with LAI, we implemented the Citizen Information Service - SIC, structuring the 
internal  flow  of  information  to  serve  citizen  within  the  terms  provided  for  by  laws  and  is  drafting  the 
Table of documents, data and information, defining restrictive information, protecting business strategic 
information  and  pursuing  the  transparent  management.  We  also  made  available  at  our  website  basic 
information required by laws and the software to citizen request information, according to the standards 
of the São Paulo State Government.  

These  duties  are  linked  to  the  Risk  Management  area  whose  main  assumption  is  the  transparency, 

quality of information and compliance with strategic rules of a listed company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON  
FINANCIAL STATEMENTS  

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

We  have  audited  the  accompanying  statement  of  financial  position  of  Companhia  de 
Saneamento  Básico  do  Estado  de  São  Paulo  -  SABESP  (the  “Company”)  as  of 
December  31,  2013  and  2012,  and  the  related  statements  of  income,  comprehensive 
income, changes in equity and cash flows for each of the two years in the period ended 
December 31, 2013. These financial statements are the responsibility of the Company’s 
management. Our responsibility is to express an opinion on  these financial statements 
based on our audits. 

We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company 
Accounting Oversight Board (United States) - PCAOB. Those standards require that we 
plan and perform  the  audit  to  obtain reasonable assurance about  whether  the  financial 
statements  are  free  of  material  misstatement.  An  audit  includes  examining,  on  a  test 
basis, evidence supporting the amounts and disclosures in the financial statements. An 
audit  also  includes  assessing  the  accounting  principles  used  and  significant  estimates 
made by management, as well as evaluating the overall financial statement presentation. 
We believe that our audits provide a reasonable basis for our opinion. 

In  our  opinion,  such  financial  statements  present  fairly,  in  all  material  respects,  the 
financial  position  of  Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo  - 
SABESP  as  of  December  31,  2013  and  2012,  and  the  results  of  its  operations  and  its 
cash  flows  for  each  of  the  two  years  in  the  period  ended  December  31,  2013,  in 
conformity  with  International  Financial  Reporting  Standards  (IFRS),  as  issued  by  the 
International Accounting Standards Board (IASB).

19(R)  –  Employee  Benefits,  and  the  change  in  the  accounting  policy  relating  to  the 
in  accordance  with  IFRS  11  -  Joint 
recording  of 
Arrangements,  the  corresponding  amounts  recorded  in  the  statement  of  financial

comprehensive income, changes in equity and cash flows for the years ended December

Accounting  Policies,  Changes  in  Estimates  and  Correction  of  Error  and  IAS  1  - 
Presentation of Financial Statements.  

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company 
Accounting Oversight Board (United States) - PCAOB, the Company’s internal control 
over  financial  reporting  as  of  December  31,  2013,  based  on  the  criteria  established  in

Report of independent registered

To the Board of Directors and Shareholders of 
Companhia de Saneamento Básico do  
Estado de São Paulo - SABESP 

In our opinion, the statements of income, of comprehensive income, of shareholders’ 
equity and of cash flows for the year ended December 31, 2011 present fairly, in all 
material respects, the results of operations and cash flows of Companhia de Saneamento 
Básico do Estado de São Paulo - SABESP (the “Company”) for the year ended 
December 31, 2011 in conformity with International Financial Reporting Standards as 
issued by the International Accounting Standards Board. These financial statements are 
the responsibility of the Company's management.  Our responsibility is to express an 
opinion on these financial statements based on our audit.  We conducted our audit of 
these statements 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 audit to obtain reasonable assurance 
about whether the financial statements are free of material misstatement.  An audit 
includes examining, on a test basis, evidence supporting the amounts and disclosures in 
the financial statements, assessing the accounting principles used and significant 
estimates made by management, and evaluating the overall financial statement 
presentation. We believe that our audit provides a reasonable basis for our opinion.   

As discussed in Note 4.1 to the financial statements, the Company changed the manner 
in which it accounted for (i) joint arrangements under IFRS 11 - Joint Arrangements 
and (ii) employee benefits under IAS 19 - Employee Benefits.

1              Operational context 

Companhia de Saneamento Básico do Estado de São Paulo ("SABESP" or the "Company") is a 
mixed-capital  company  headquartered  in  São  Paulo,  at  Rua  Costa  Carvalho,  300,  CEP  05429-
900, 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,  as  well  as  it  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,   in  a  sustainable  and  competitive  manner,  with  excellence  in 
customer service. 

On December 31, 2013, the Company operated water and sewage services in 363 municipalities 
of  the  State  of  São  Paulo.  Most  of  these  municipalities  operations  are  based  on  30-year 
concession,  program  and  services  contracts.  The  Company  has  two  partial  contracts  with  the 
municipality of Mogi das Cruzes; however, since most of municipality is serviced by wholesale, it 
was  not  included  in  the  363  municipalities.  On  December  31,  2013,  the  Company  had  365 
contracts. 

SABESP is not temporarily operating in some municipalities due to judicial orders. The lawsuits 
in  progress  refer  to  Iperó,  Cajobi,  Álvares  Florense, Macatuba  and  Embaúba, and the carrying 
amount  of  these  municipalities'  intangible  assets  was  R$11,351  as  of  December  31,  2013 
(R$16,516 as of December 31, 2012). 

As  of  December  31,  2013,  61  concession  agreements  had  expired  and  are  being  negotiated. 
From   2014  to  2034,  38  concession  agreements  will  expire.  Management  believes  that 
concession  agreements  expired  and  not  yet  renewed  will  result  in  new  contracts,  disregarding 
the  risk  of  discontinuity  in  the  provision  of  municipal  water  supply  and  sewage  services.  By 
December  31,  2013,  266  program  and  services  contracts  were  signed  (258  contracts  on 
December 31, 2012). 

As  of  December  31,  2013,  the  carrying  amount  of  the  underlying  assets  used  in  the  61 
concessions of the municipalities under negotiation totaled R$5,972,414, accounting for 25.05% 
of total, and the related revenue for the year then ended totaled R$1,930,348 on December 31, 
2013, accounting for 16.11% of total. 

The Company's operations are concentrated in the municipality of São Paulo, which represents 
51.75% of the gross revenues on  December 31, 2013 (51.21% in December 2012 and 51,43% in 
December 2011) and 42.46% of intangible assets (43.51% in December 2012).   

On June 23, 2010, the State of São Paulo, the Municipality of São Paulo, the Company and the 
regulatory agency “Sanitation and Energy Regulatory Agency – ARSESP” 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, 
pursuant  to  the  law.  This  agreement  sets  forth  SABESP  as  the  exclusive  service  provider  and 
designates 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.  

In the municipality of Santos, in the Santos coast 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. As of December 31,   2013 the carrying amount 
of the municipality of Santos’ intangible assets was R$340,530 (R$328,693 in December 2012) 
and  gross  revenue  in  the  year  ended  December  31,  2013  was  R$249,393  (R$202,103  in 
December 2012 and R$196,831 in December 2011). 

Article 58 of Law 11,445/07 determines that precarious and expired concessions, as well as those 
effective  for  an  undetermined  period  of  time,  including  those  that  do  not  have  an  instrument 
formalizing  them,  will  be  valid  until  December  31,  2010.  However,  Article  2  of  Law  12,693  of 
July 24, 2012 allows program agreements to be executed until December 31, 2016. 

The Company’s Management understands that the concession agreements not yet renewed are 
valid and are governed by Laws 8,987/95 and 11,445/07, including those municipalities served 
without an agreement. 

Public deeds are valid and governed by the Brazilian Civil Code.  

The  Company's  shares  have  been  listed  in  the  Novo  Mercado  (New  Market)  segment  of 
BM&FBovespa  under  the  ticker  symbol  SBSP3  since  April  2002  and  on  the  New  York  Stock 
Exchange  (NYSE)  as  American  Depositary  Receipts  (“ADRs”)  Level  III,  under  the  SBS  code, 
since  May  2002.  In  2007,  SABESP  adhered  to  the  Corporate  Sustainability  Index,  or  ISE  of 
BM&FBovespa, which reflects the high level of commitment with sustainable development and 
social practices. 

Since  2008,  the  Company  has  been  setting  up  partnerships  with  other  companies,  which 
resulted  in  the  following  companies:  Sesamm,  Águas  de  Andradina,  Saneaqua  Mairinque, 
Aquapolo  Ambiental,  Águas  de  Castilho  and  Attend  Ambiental.  Although  SABESP  has  no 
majority interest in the capital stock of these companies, the shareholders’ agreements provide 
for  the  power  of  veto  and  casting  vote  in  certain  issues  jointly  with  associates,  indicating  the 
shared control in the management of investees. 

The financial statements were approved by the Management on April 25, 2014.

2             Basis of preparation and presentation of the financial statements 

The  financial  statements  of  the  Company  have  been  prepared  in  accordance  with  the 
International  Financial  Reporting  Standards  ("IFRS"),  issued  by  the  International  Accounting 
Standards Board (“IASB”). These policies have been consistently applied to all 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 
financial statements are described in Note 5.  

3             Summary of Significant Accounting Practices 

Main  accounting  policies  applied  in  the  preparation  of  these  financial  statements  are  defined 
below. These policies have been applied consistently in all years presented.  

3.1  Cash and cash equivalents 

Cash  and  cash  equivalents  include  cash  in  hand,  bank  deposits,  other  short-term  highly liquid 
investments with original maturities less than three months as of the investment date, with an 
insignificant risk of changing value, as well as current account overdrafts.  

3.2  Financial instruments 

Classification 

The  Company  classifies  its  financial  assets  according  to  the  following  categories:  measured  at 
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  acquired. 
Management determines the classification of the financial assets at inception. On December 31, 
2013 and 2012, the Company did not have financial assets classified under the fair value through 
profit or loss, held-to-maturity and available-for-sale financial instruments category.  

Financial assets calculated at fair value through profit or loss 

These are financial assets held for trading. A financial asset is classified into this category when 
mainly acquired for sale purposes in the 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.

Amounts in thousands of reais, unless otherwise indicated  

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  statement  of 
financial  position  date  (these  are  classified  as  noncurrent  assets  or  liabilities).  The  Company's 
loans and receivables include cash and cash equivalents, balances of trade accounts receivable, 
accounts receivable from related parties, other accounts receivables, receivables from the Water 
National  Agency  –  ANA,  contractors  and  suppliers,  loans  and  financing,  services  payable, 
balances  payable  from  public-private  partnership  (PPP),  and  program  contract  commitments. 
Loans and receivables are recorded at fair value and subsequently at amortized cost, under the 
effective interest rate method.  

3.3  Operating income 

(a)              Revenue from water and sewage 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. 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. Concerning revenues of wholesale municipal governments 
which do not pay the full invoice, the Company records an allowance for doubtful accounts upon 
invoicing in revenue reduction account. 

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.

Amounts in thousands of reais, unless otherwise indicated  

(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  from  cost  plus  contracts  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. 

3.4  Trade accounts receivable and allowance for doubtful accounts 

Trade  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 current guarantees and it does not expect to 
incur in additional significant losses.  

3.5  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.   

3.6 Investment Properties 

The investment properties are recorded at the acquisition or construction cost, less accumulated 
depreciation, calculated by the straight-line method at rates that consider the estimated useful 
life of assets. Expenditures related to repairs and maintenance are recorded in the statement of 
income when incurred.  

The Company also maintains few assets for indeterminate use in the future, i.e., it is not defined 
if  the  Company  will  use  the  property  in  the  operation  or  sell  the  property  in  the  short  term 
during the ordinary course of business.  

3.7  Property, plant and equipment 

Property,  plant  and  equipment  comprise  mainly  administrative  facilities  not  composing  the 
assets,  subject-matter  of  the  concession  agreements.  Those  assets  are  stated  at  historical 
acquisition  or  construction  cost  less  depreciation,  net  of  impairment  charge,  when  necessary. 
Interest,  other  financial  charges  and  inflationary  effects  deriving  from  financing  effectively 
applied  to  construction  in  progress  are  recorded  as  cost  of  respective  property,  plant  and 
equipment.

Amounts in thousands of reais, unless otherwise indicated  

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 statement of income during the financial period in which they 
were incurred.  

Depreciation is calculated using the straight-line method to allocate their cost and is described 
in Note 14(c). Lands are not depreciated. 

Residual  values  and  the  useful  life  of  assets  are  revised  and  adjusted,  where  applicable,  at  the 
end of each year.  

Gain  and  losses  on  disposals  are  determined  by  the  difference  between  the  proceeds  with  the 
carrying amount and are recognized within other operating income (expenses) in the statement 
of income.  

3.8  Intangible assets 

Intangibles are stated at acquisition cost and/or construction of the underlying assets, including 
construction  margin,  interest  and  other  financial  charges  capitalized  during  the  construction 
period, in this case, for the qualifying assets. 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, which corresponds to one fiscal year of SABESP.   

The intangible has its amortization initiated when the intangible assets are available for use in 
location and the necessary condition established by the Company.   

The  amortization  of  intangible  assets  reflects  the  period  over  the  expected  future  economic 
benefits generated by the intangible asset are consumed by the Company and can be the period 
of the contract or the useful life of the asset.  

The amortization of the intangible assets is discontinued when the asset is totally consumed or it 
is disposed of, whatever occurs first.    

Donations  in  assets  to  the  concession  grantor  received  from  third  parties  and  governmental 
entities  to  allow  the  Company  to  render  water  and  sewage  supply  services  are not  recorded in 
the Company’s financial statements, since these assets are controlled by the concession grantor.

(a)              Concession arrangements/programs 

The  Company  operates  concession  agreements  including  the  rendering  of  basic  sanitation, 
environmental, water supply and sewage collection services signed 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)         The  grantor  controls  or  regulates  what  services  the  operator  must  provide  with  the 

infrastructure, to whom it must provide them, and at what price; and 

(ii)        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 is recognized as revenue, as 
its  fair  value,  when  the  infrastructure  is  built,  provided  that  this  work  is  expected  to  generate 
future economic benefits. The accounting policy to recognize construction revenue is described 
in Note 3.3 “Operating income”. 

Intangible  assets  related  to  Concession  agreements  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, 
whichever occurs first.  

Investments made and not recovered through rendering of services, within the agreement term, 
must  be  indemnified  by  the  concession  grantor,  (1)  with  cash  or  cash  equivalents  or  also,  in 
general  (2)  with  the  contract  extension.  These  investments  are  amortized  by  the  useful  life  of 
asset. 

Law  11,445/07  indicates,  whenever  possible,  that  basic  sanitation  public  utilities  will  have  the 
economic  and  financial  sustainability  ensured  through  the  remuneration  due  to  service 
collection, preferably as tariffs and other public prices, which may be established for each service 
or  both  jointly.  Therefore,  investments  made  and  not  recovered  through  services  rendered, 
within  original  term  of  the  contract,  are  recorded  as  intangible  assets  and  amortized  by  the 
useful life of the asset, taking into consideration a solid track record of concession renewal and, 
therefore, the continuity of services. 

(b)                Software licenses 

Software licensing is capitalized based on the acquisition costs and other implementation costs. 
Amortizations  are  recorded  according  to  the  useful  lives  and  the  expenses  associated  with 
maintaining these are recognized as expenses when incurred.

3.9  Impairment of non-financial assets 

Property,  plant  and  equipment,  intangibles  and  other  noncurrent  assets  with  definite  useful 
lives, are yearly reviewed for impairment whenever events or changes in circumstances indicate 
that the carrying amount may not be recoverable.   

The  Company  does  not  record  assets  with  indefinite  useful  life  and  assessed  that  there  are  no 
indications of impairment losses. 

3.10  Trade accounts payable 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  noncurrent  liabilities  and  are  initially  measured  at  fair  value,  which  generally 
correspond to the bill and subsequently at amortized cost. 

3.11  Loans and financing 

Borrowings are initially recognized at fair value, upon receipt of funds, net of transaction costs. 
Subsequently,  borrowings  are  stated  at  amortized  cost,  as  presented  in  Note  15.  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  issued  by  the  Company  are  recognized  in  a  similar  manner  to 
borrowings.  

3.12  Borrowing costs 

Borrowing  costs  attributable  to  acquisition,  construction  or  production  of  an  asset,  which, 
necessarily, requires a substantial time period to be ready for use or sale are capitalized as part 
of the cost of these assets. Other borrowing costs are recognized as expenses in the period they 
are  incurred.  Borrowing  costs  are  interest  rates  and  other  charges  incurred  by  the  Company 
related to loans, including exchange variation, as described below.  

The  capitalization  occurs  during  the  period  in  which  the  asset  has  been  built,  considering  the 
weighted average rate of loans effective on the capitalization date.  

For  foreign  currency-denominated  loans  or  financing,  the  Company  analyzes  them  as  if  they 
were  contracted  in  local  currency,  restricting  the  capitalization  of  interest  and/or  exchange 
variation  by  the  amount  that  would  be  capitalized  if  these  were  contracted  in  the  domestic 
market.

3.13  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.  

3.14  Profit sharing 

The  Company's  profit  sharing  plan  for  its  employees  is  based  on  targets  of  the  Company  as  a 
whole,  and  based  on  the  performance  of  each  business  unit.  The  Company  recognizes  a 
provision when it is contractually required or when there is a practice in the past that created a 
constructive obligation. The accrual for profit sharing is recorded on the accrual basis period as 
operating expenses and operating cost.   

3.15   Provisions,  legal  liabilities,  escrow  deposits,  securities  deposits  and 
contingent assets 

Provisions  related  to  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  disbursements  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 provision is stated net of the related escrow 
deposits based on the legal right to offset. The bases and the nature of the provisions for civil, 
tax, labor and environmental risks are described in Note 18. 

Escrow  deposits  not  linked  to  related  liabilities  are  recorded  in  noncurrent  assets.  Escrow 
deposits are restated for inflation. 

Contingent assets are not recognized in the books.  

3.16  Environmental costs 

Costs related to ongoing environmental programs are expensed in the income statement, when 
there  is  any  indication  of  an  event.  Ongoing  programs  are  designed  to  minimize  the 
environmental impact of the operations and to manage the environmental risks inherent to the 
Company's activities.   

3.17  Income taxes – current and deferred 

Income taxes expenses comprise current and deferred income tax and social contribution.

For information about the Transition Tax Regime (RTT) and Provisional Measure 627/2013, see 
Note 17 (e) and (f), respectively. 

Current tax 

The provision for income tax and social contribution is based on the taxable income for the year. 
The income tax was accrued at rate 15%, plus 10% surtax on taxable income exceeding R$ 240. 
The social contribution was accrued at rate 9% over adjusted net income. 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. Income tax and social contribution are accrued based on legislation in place in 
the end of the year. 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.  

Deferred tax 

Deferred income tax is recognized, using the liability method, on temporary differences arising 
between  the  tax  basis  of  assets  and  liabilities  and  their  carrying  amounts  in  the  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  that  at  the  time  of  the 
transaction  affects  neither  accounting  nor  taxable  profit  nor  loss,  except  for  business 
combinations.  Deferred  income  tax  is  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.  

Deferred  income  tax  and  social  contribution  assets  are  recognized  only  to  the  extent  that  it  is 
probable  that  future  taxable  profit  will  be  available  for  which  temporary  differences  can  be 
utilized and tax losses can be carryforward.  

Deferred  taxes  assets  and  liabilities  are  offset  when  there  is  a  legally  enforceable  right  of 
offsetting current tax assets against current tax liabilities and when deferred income tax assets 
and liabilities are related to income taxes levied by same tax authority over the tax entity.   

3.18              Taxes on revenues 

Revenues from water and sewage services are recognized on accrual basis for PASEP and Cofins, 
calculated at the rates of 1.65% and 7.60%, respectively. Taxes levied on billed amounts to public 
entities are due when bills are received. 

As these taxes are calculated by the non-cumulativeness regime and presented net of tax credits, 
as deductions from gross revenues. Debts measured on “other operating income” are presented 
as deductions from the respective operating income or expense.

3.19  Pension obligations 

(a)         Defined benefit 

The  Company  makes  contributions  to  defined  benefit  plans  on  a  contractual  basis  and 
sponsored  thereby,  managed  by  Fundação  Sabesp  de  Seguridade  Social  –  SABESPREV,  a 
supplementary private pension closely-held entity. The regular contributions are recognized in 
the statement of income for the period.  

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 assets. The defined 
benefit  obligation  (G1)  and  (G0)  are  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.  

Referring to actuarial gains and losses deriving from adjustments based on the experience and 
changes  in  actuarial  assumptions  are  directly  recorded  under  equity,  as  other  comprehensive 
income  (OCI),  so  that  the  plan's  net  assets  or  liabilities  are  recognized  in  the  statement  of 
financial position in order to reflect the full amount of plan’s deficit or surplus. 

The expenses related to pension plan are recognized in profit and loss of the year as operating 
cost, selling expenses or administrative expenses, according to employee’s allocation.   

In  an  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 
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.  

(b)         Defined contribution 

The  Company  makes  contributions  to  defined  contribution  plans  (Sabesprev  Mais)  on  a 
contractual basis and sponsored thereby, managed by Fundação Sabesp de Seguridade Social – 
SABESPREV,  a  supplementary  private  pension  closely-held  entity  that  provides  post-
employment benefits to its employees. 

A  defined  contribution  plan  is  a  pension  plan  according  to  which  the  Company  makes  fixed 
contributions to a separate entity. The Company has no obligation of making contributions if the 
fund has no sufficient funds to pay to all employees the benefits related to employee’s services in 
current and previous period.

3.20  Financial income and expenses 

Financial  income  is  primarily  comprised  of  interest,  inflation  adjustments  and  exchange 
variations on escrow deposits and negotiations with customer to pay by installments, using the 
effective interest rate method. 

Financial  expenses  are  primarily  comprised  of  interest,  inflation  adjustments  and  exchange 
variations on loans and financing, refinancing, provisions, public-private partnership, program 
contract  commitments  and  provisions.  These  financial  income  and  expenses  are  calculated 
using the effective interest rate method.   

Inflation  adjustments  and  foreign  exchange  gains  and  losses  derive  from  the  collection  or 
payment to third parties, as contractually required by law or court decision, and recognized on 
an accrual basis pro rata temporis.  

Inflation  adjustments  included  in  the  agreements  are  not  considered  embedded  derivatives, 
since they are deemed as inflation adjustment rates for the Company’s economic scenario. 

3.21  Leases  

Lease agreements are classified as financial lease when property, risks and rewards inherent to 
the  ownership  of  asset  to  the  lessee  are  transferred.  Other  leases  are  classified  as  operational 
lease, recognized as expenses in the statement of income on a straight-line basis during the lease 
term.  

Financial lease agreements are measured based on the lower amount between the present value 
of minimum mandatory payments of the agreement or fair value of asset on the start date the 
lease  agreement.  The  amounts  payable  deriving  from  considerations  of  financial  lease 
agreements  are  recognized  and  allocated  between  financial  expenses  and  amortization  of 
financial  lease  payables  so  that  to  obtain  a  constant  interest  rate.  The  corresponding  lessor’s 
liability is recorded as current and noncurrent debt.  

3.22  Other current and noncurrent assets and liabilities 

Other assets are stated at cost of acquisition, net of any impairment loss, where applicable. The 
amounts  recognized  as  other  liabilities  are  stated  at  known  or  estimated  amounts,  including, 
where applicable, related charges and monetary variations.  

3.23  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 9249/95 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  its  by-laws.  Dividends  and  interest  on 
shareholders´  equity  over  the  minimum  established  in  the  by-laws  are  recognized  when 
approved  by  the  shareholders  in  the  general  meeting.  The  tax  effects  of  the  interest  on

3.24  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.  

3.25 Segment reporting 

Operating  segments  are  reported  in  a  manner  consistent  with  the  Management  internal 
reporting  to  make  strategic  decisions,  allocate  resources  and  evaluate  the  operating  segment 
performance.  

Based on how the Company treats its business and how decision-making of resources allocation 
is  made,  two  operating  segments  (water  and  sewage)  were  stated  for  financial  reporting 
purposes. The segment reporting is detailed in Note 23. 

3.26  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$),  which  is  also  the  Company's  functional  and 
presentation  currency.  All  financial  information  presented  has  been  presented  in  reais,  except

amendments  aim  at  providing  greater 
transparency  to  risk  exposures  when  a

also require the disclosure of transfer of 
financial  assets  when  not  equally

Pursuant  to  IFRS  10,  there  is  only  one 
basis of consolidation for all entities, i.e., 
the  control.  This  change  removes  the 
the  previous

(a)          Adoption of IFRS 11 

The  joint  investees  (Note  11)  started  to  be  classified  as  joint  venture  and  are  subject  to  the 
accounting recognition by the equity method under IAS 28. This amendment implied to change 
the proportional consolidation to account for investment by the equity method. 

The  adoption  of  IFRS  11  resulted  in  changes  in  the  consolidation  for  investments  held  by  the 
Company in Sesamm – Serviços de Saneamento de Mogi Mirim S/A, Águas de Andradina S.A., 
Águas  de  Castilho,  Saneaqua  Mairinque  S.A.,  Aquapolo  Ambiental  S.A.  and  Attend  Ambiental

SABESP 

Notes to the Financial Statements 
Years Ended December 31, 2013 and 2012 
Amounts in thousands of reais, unless otherwise indicated  

The Company’s accounting practice until December 31, 2012 was to account for actuarial gains 
and losses by the “corridor” approach, where gains and losses deriving from changes in actuarial 
assumptions were only recognized in profit or loss to the extent they exceed the “corridor” value 
and amortized over the remaining estimated average life of population which holds the benefits; 
therefore, the actuarial gains and losses measured in a period were not recognized immediately. 
As  a  result  of  this  method,  the  value  recognized  in  liabilities  differed  from  estimated  present 
value of liabilities by the amount of actuarial gains and losses not yet recognized. 

With the adoption of the new accounting standard, SABESP started to record in the statement of 
financial  position  the total  effect  of  actuarial  losses, net  of  income  tax  and  social  contribution, 
against  other  comprehensive  income;  i.e.,  without  carrying  through  the  statement  of  income. 
This  accounting  has  been  applied  during  2013  interim  accounting  information,  with 
retrospective  effect  on  the  Company’s  financial  statements  for  the  fiscal  year  ended  December 
31, 2012 and the opening balance as at January 1, 2012. 

Deferred income tax and social contribution were accounted for only for G1 plan, since the G0 
plan’s expenses are not tax deductible. 

Below, the reconciliation of new balance sheet balances of actuarial liabilities for the fiscal year 
ended December 31, 2012 and the opening balance, on January 1, 2012, affected by amendment 
to the standard:

The Company's activities are exposed to Brazilian economic scenario, expositing to market risk, 
such as exchange rate, interest rate, credit risk and liquidity risk. The Company’s financial risk 
management  is  focused  on  the  unpredictability  of  financial  markets  and  seeks  to  minimize 
potential adverse effects on the Company’s financial performance.  

The Company has not utilized derivative instruments in any of the periods reported. 

(a)        Market risk 

Foreign currency risk 

SABESP’s  foreign  exchange  exposure  implies  market  risks  associated  with  Brazilian  real  
currency  fluctuations  against  the  US  dollar  and  yen.  SABESP’s  foreign  currency-denominated 
liabilities mainly include US dollar and yen-denominated loans.   

In  case  of  Brazilian  real   depreciation  in  relation  to  foreign  currency  in  which  the  debt  is 
denominated, SABESP will incur in monetary loss in relation to such debt.

SABESP’s  specific  foreign  currency  risks  are  related  to  exposures  caused  by  its  current  and 
noncurrent debts denominated in foreign currency.   

The  management  of  SABESP’s  foreign  currency  exposure  considers  several  current  and 
projected economic factors, besides market conditions.  

This  risk  arises  from  the  possibility  that  the  Company  may  incur  losses  due  to  exchange  rate 
fluctuations  that  would  impact  liability  balances  of  foreign  currency-denominated  loans  and 
financing raised in the market and related financial expenses. The Company does not maintain 
hedge or swap contracts or any financial instrument to hedge against this risk, but conducts an 
active  management  of  debt,  taking  advantage  of  opportunities  to  swap  expensive  debts  with 
“cheaper” debts, reducing the cost through early maturity. 

A significant amount of the Company’s financial debt is indexed to the U.S. dollar and Yen, in 
the total amount of R$3,715,645 on December 31, 2013 (R$3,231,183 in December 2012). Below,

As of December 31, 2013, if the Brazilian real had appreciated or depreciated by 10% against the 
US dollar and Yen with all other variables remaining constant, effects on results before taxes for 
the year would have been R$371,564 (R$323,118 in December 2012), lower or higher, mainly as 
a result of foreign exchange losses or gains on the translation of foreign currency-denominated 
loans. 

Scenario  I  below  presents  the  effect  in  net  income  for  the  next  12  months,  considering  the 
projected  rates  of  the  U.S.  dollar  and  the  Yen.  Considering  the  other  variables  as  remaining 
constant,  the  impacts  for  the  next  12  months  are  shown  in  scenarios  II  and  III  with  possible 
depreciations of 25% and 50%, respectively, in the Brazilian Real.

Interest rate risk 

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. 

The  Company  has  not  entered  into  any  derivative  contract  to  hedge  against  this  risk;  however 
continually monitors market interest rates, in order to evaluate the possible need to replace its 
debt.   

The table below provides the Company's loans and financing subject to variable interest rate:

(iv) IPCA (Índice Nacional de Preços ao Consumidor Amplo), a consumer price index 
(v) LIBOR - London Interbank Offered Rate 

Another  risk  to  which  the  Company  is  exposed,  is  the  mismatch  between  the  inflation 
adjustment  indices  of  its  loans  and  financing  with  those  of  its  service  revenues.  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, 2013, if interest rates on loans and financing denominated in Brazilian reais  
had been 1% higher or lower with all other variables held constant, the effects on profit for the 
year  before  taxes  would  have  been  R$69,831  (R$67,015  in  December  2012)  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 basis and retail customers, including outstanding accounts 
receivable,  restricted  cash,  accounts  receivable  from  related  parties  and  indemnities.  The 
Company is required by law to invest its funds  with Banco do  Brasil  (rating  AA+(bra)).  Credit 
risk exposure is mitigated by sales to a dispersed customer base. 

The  maximum  exposure  to  credit  risk  at  the  reporting  date  are  the  carrying  amounts  of  
instruments  classified  as  cash  equivalents,  deposits  in  banks  and  financial  institutions, 
restricted  cash,  trade  accounts  receivable  and  accounts  receivable  from  related  parties  in  the 
balance sheet date. (See notes 6, 7, 8 and 9).  

Regarding the financial assets held with financial institutions, the credit quality that is not past 
due  or  subject  to  provision  for  impairment  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  deposits  and  financial  investments,  the 
Company considers the lower rating of the counterparty published by three main international 
rating  agencies  (Moody's,  Fitch  and  S&P),  according  to  internal  policy  of  market  risk 
management:

The  Company's  liquidity  is  primarily  reliant  upon  cash  provided  by  operating  activities,  loans 
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, as well as the payment of debts. 

The funds held by the Company are invested in interest-bearing current accounts, time deposits, 
short-term deposits and securities, selecting instruments with appropriate maturity or liquidity 
sufficient to provide margin as determined by projections mentioned above.

Future  interest  was  calculated  based  on  the  contractual  clauses  for  all  agreements.  For 
agreements  with  floating  interest  rate,  the  interest  rates  used  correspond  to  the  base  dates 
above. 

Cross default 

The Company has loan agreements including cross default clauses, i.e., the early maturity of any 
Company’s  debt  will  imply  the  early  maturity  of  these  agreements.  The  indicators  are 
continuously monitored in order to avoid the execution of this clause. 

4.4 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  less  cash  and  cash 
equivalents.  Total  capital  is  calculated  as  total  equity  as  shown  in  the  statement  of  financial 
position plus net debt.

Amounts in thousands of reais, unless otherwise indicated  

On December 31, 2013 the leverage ratio fell to 37% versus the 38% recorded on December 31, 
2012,  due  to  an  increase  in  equity  deriving  from  profit  for  the  year  and  other  comprehensive 
income. 

4.5 Fair value estimates 

It  is  assumed  that  balances  from  trade  accounts  receivable  (current)  and  trade  payables  to 
suppliers by carrying amount, less impairment approximate fair values, considering their short 
maturity.  Noncurrent trade  accounts  receivable  also approximate their  fair values,  as they will 
be adjusted by inflation and/or will bear contractual interest rates over time.

Amounts in thousands of reais, unless otherwise indicated  

To obtain fair value of loans and financing, the following criteria have been adopted: 

(i)       Agreements with Banco do Brasil and CEF (Federal Savings Bank) were projected until 
final  maturity,  at  contractual  rates  (projected  TR  +  spread)  and  discounted  at  present 
value by TR x DI, both rates were obtained from BM&FBovespa.   

(ii)      Debentures  were  projected  up  to  the  final  maturity  date  according  to  contractual  rates 
(IPCA, DI, TJLP or TR), and discounted to present value considering the future interest 
rate published by ANBIMA in the secondary market, or by market equivalent rates, or the 
Company’s share traded in the Brazilian market.   

(iii)    BNDES  loans  are  financial  instruments  valued  at  carrying  amount  plus  contractual 

interest rate till mature date, and are indexed by long term interest rate – TJLP.   

These loans have specific characteristics and the terms and conditions defined in the loan 
agreements  with  BNDES  between  independent  parties,  and  reflect  the  conditions  for 
those  types  of  loan.  In  Brazil,  a  consolidated  market  of  long-term  debts  does  not  exist 
with  the  same  characteristics  of  BNDES  loans,  the  offering  of  credit  to  the  entities  in 
general, with this long-term characteristic, usually is restricted to BNDES. 

(iv)    Other  financing  in  local  currency  are  valued  at  its  nominal  amount  plus  contractual 
interest  incurred  through  maturity,  discounted  to  present  value  considering  a  future 
interest rate published by BM&FBovespa. 

(v)      Agreements  with  IDB,  IBRD,  were  projected  until  final  maturity  in  origin  currency, 
applying  interest  rates  contracted,  discounted  at  present  value  at  Libor  futures  rate, 
obtained  from  Bloomberg.  Eurobonds  were  priced  at  market  value  through  quotes 
published by Bloomberg. All the amounts obtained were translated into Brazilian reais  at 
the exchange rate as of December 31, 2013.  

(vi)    Agreements  with  JICA,  were  projected  until  final  maturity  in  origin  currency,  using 
interest  rates  contracted  and discounted  at  present value,  at  Tibor  futures  rate  obtained 
from  Bloomberg.  The  amounts  obtained  were  translated  into  Brazilian  reais  at  the 
exchange rate as of December 31, 2013.  

(vii)    Leases  are  financial  instruments  valued  at  their  nominal  amount  plus  contractual 
interests  incurred  through  maturity  date,  and  are  indexed  to  fixed  contractual  interest 
rate,  which  is  a  specific  rate  and  cannot  be  compared  to  any  other  rate  available  in  the 
market.  The  Company  considers  the  fair  value  the  same  amount  recognized  in  the 
financial statements as of December 31, 2013. 

Considering the nature of other financial instruments, assets and liabilities of the Company, the 
balances  recognized  in  the  statement  of  financial  position  approximate  the  fair  values,  taking 
into account the maturities close to the end of the reporting period, comparison of contractual 
interest rates with market rates in similar operations at the end of the reporting periods, their 
nature and maturity terms.

5    Main 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 trade accounts receivable, 
in accordance with the accounting policy stated in Note 3.4. 

The  methodology  for  determining  the  allowance  for  doubtful  accounts  receivable  requires 
significant  estimates,  considering  a  number  of  factors  including  historical  receipt  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 and program contracts 

The Company recognizes as intangible assets arising from concession agreements. 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 fixed asset.  

Concession intangible assets under Concession agreements 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 asset or contract period, which occurs first. Additional information on the 
accounting for intangible assets arising from concession agreements is described in Note 3.8. 

The  recognition  of  fair  value  for  the  intangible  assets  arising  on  concession  agreements  is 
subject  to  assumptions  and  estimates,  and  the  use  of  different  assumptions  could  affect  the 
balances  recorded.  Different  assumptions  and  estimates  and  changes  in  future  circumstances, 
could affect the remaining useful lives of the intangible assets and have a significant impact on 
the results of operations.

(c)              Provisions  

The Company is party to a number of legal proceedings involving significant claims. These legal 
proceedings  include,  but  are  not  limited  to,  tax,  labor,  civil,  environmental,  disputes  with 
customers and suppliers and other proceedings. The Company accrues for lawsuits to which it is 
probable that an outflow will be necessary to settle the liability and the amount of such loss can 
be  reasonably  estimated.   Judgments  regarding  future  events,  the  results  of  which  may  differ 
significantly  from  actual  estimates  and  could  exceed  the  amounts  provisioned.  Provisions  are 
revised  and  adjusted  to  take  into  consideration  changes  in  circumstances  involved.  Additional 
information of these legal proceedings is disclosed in Note 18. 

(d)             Pension benefits 

The Company sponsors the defined benefit plan and the defined contribution plan, as described in 
Note 19. 

The liability recognized in the balance sheet in relation to defined benefit pension plans is the 
present value of defined benefit obligation on the balance sheet date, less the fair value of plan 
assets. The defined benefit obligation is calculated yearly by independent actuaries, applying the 
projected credit unit method. The present value of defined benefit obligation is determined by 
discounting the estimated future cash outflows, using interest rates compatible with the market, 
which are denominated in currency in which benefits will be paid and with maturity terms close 
to those of corresponding pension plan obligation.  

(e)              Deferred income tax and social contribution 

The Company recognizes and settles taxes on income based on the results of operations verified 
according  to  the  Brazilian  Corporation  Law,  taking  into  consideration  the  provisions  of  the  tax 
laws. Pursuant to IAS 12, the Company recognizes deferred tax assets and liabilities based on the 
differences between the accounting balances and the tax bases of assets and liabilities.  

The Company regularly reviews the recoverability of deferred tax assets and recognizes a provision 
for impairment if  it is probable that  these assets will not be realized, based on the historic taxable 
income,  in  the  projection  of  future  taxable  income  and  the  estimated  period  of  reversing 
temporary differences. These calculations require the use of estimates and assumptions. The use 
of  different  estimates  and  assumptions  could  result  in  provision  for  impairment  of  all  or  a 
significant amount of deferred tax assets.

deposited at Banco do Brasil, whose original maturities are lower than three months, which are 
convertible into a cash amount and subject to an insignificant risk of change in value.  

The  average  yield  of  financial  investments  corresponds  to  100.00%  of  CDI  in  December  2013 
(100.01% in December 2012).  

7             Restricted cash 

On December 31, 2013, the Company’s restricted cash, under current assets, totaled R$10,333, 
mainly  referring  to  the  agreement  in  the  municipality  of  São  Paulo,  where  the  Company 
transfers  7.5%  of  the  municipality’s  revenue  to  the  Municipal  Fund  (December  2012  – 
R$64,977). 

The  variation  occurred  in  the  period  between  January  and  December  2013  when  compared  to 
the Financial Statements as at December 31, 2012, mainly refers to the release of restriction of 
use of funds by the Municipal Government of São Paulo.

(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  with  usual  market  terms  and 
conditions,  as  considered  by  management,  except  for  the  settlement  of  credits  which  can  be 
made according to items (iii), (iv) and (v).   

An allowance for losses of amounts past due for more than 360 days has been recorded due to 
the uncertainty involving these receipts (R$46,674 in 2013 and R$47,531 in 2012). 

(ii) Reimbursement for pension benefits paid   

Refers to amounts of supplementary retirement and pension benefits provided for in State Law 
4819/58 ("Benefits") paid by the Company to former employees and pensioners, referred to as 
Go.  

Under the Agreement referred on item (iii) with the São Paulo State Government ("GESP" or the 
"State"), 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  (vi),  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.  

See additional information about the Go plan in Note 19 (b) (iii). 

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

(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  retirement 
benefits.  

In  view  of  the  strategic  importance  of  the  Taiaçupeba,  Jundiaí,  Biritiba,  Paraitinga  and  Ponte 
Nova reservoirs for ensuring and maintaining the Alto 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 challenges the legal validity of this agreement, and 
its main argument is the lack of bidding and the absence of a specific legislative authorization 
for disposal of DAEE's assets. There is an unfavorable decision to SABESP not yet unappealable. 
The Company's legal advisors assess the risk of loss in this lawsuit as probable. See additional 
information in item (vi) below.   

(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. In December 2012 
the last installment was paid.  

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$915,251, monetarily adjusted up to September 2008 in accordance with the fluctuation of the 
IPCA-IBGE,  corresponding  to  the  Undisputed  Reimbursement,  determined  by  FIPECAFI. 
SABESP  accepted  on  a  provisional  basis  the  reservoirs  (see  item  (iii)  above)  as  part  of  the 
payment  of  the  Undisputed  Reimbursement  and  offered  to  GESP  a  provisional  settlement, 
recognizing a credit totaling R$ 696,283, corresponding to the value of the reservoirs in the Alto 
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-IBGE 
fluctuation, plus interest of 0.5% p.m., the first of which fell due on November 25, 2008.  

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 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 previously defined as 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 controversial receivables without dispute.

Amounts in thousands of reais, unless otherwise indicated  

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. Despite the legal action 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, 2013 and 
2012, the amounts not recorded by the Company, related to the pension benefits paid on behalf 
of  the  State  by  the  Company,  totaled  R$1,412,479  and  R$1,351,210,  respectively,  including the 
amount  of  R$696,283  related  to  the  transfer  of  the  reservoirs  in  the  Alto  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.  As  of  December  31,  2013  and 
2012,  the  pension  benefit  obligations  of  Plan  G0  totaled  R$1,780,268  and  R$1,987,718, 
respectively.  For  detailed  information  on  the  pension  benefit  obligations  refer  to  Note  19  (b)

(b)          Contingent assets - GESP (not recorded) 

As  mentioned  above,  on  December  31,  2013  and  December  31,  2012,  SABESP  had  contingent 
assets with GESP, not recorded in assets referring to the additional retirement and pension paid 
(Law 4,819/58), as follows:

(c)          Use of reservoirs - EMAE 

Empresa Metropolitana de Águas e Energia S.A. -  EMAE plans to receive for the credit and to 
obtain  financial  compensation  for  the  use  of  water  from  the  Guarapiranga  and  Billings 
reservoirs,  which  SABESP  uses  in  its  operations,  as  well  as  the  reimbursement  of  damages 
related to the failure to pay appropriately.  

The  Company  understands  that  no  amounts  are  due  for  the  use  of  these  reservoirs  given  the 
grants  already  made.  Should  these  reservoirs  not  be  available  for  use  to  the  Company,  there 
could  be  the  need  to  collect  water  in  more  distant  places.  There  is  a  risk  of  not  properly 
rendering services in the region, besides increasing water supply cost.  

Several  lawsuits  were  filed  by  EMAE,  among  them  a  lawsuit  to  create  an  arbitration  clause 
related to the Guarapiranga reservoir, a proceeding which had already started and another one, 
equally  pleading  for  financial  compensation  due  to  SABESP’s  water  collect  from  Billings 
reservoir  for  public  supply,  these  two  lawsuits  alleging  that  this  conduct  has  been  causing 
permanent  and  growing  loss  in  the  capacity  of  generating  electricity  of  Henry  Borden 
hydroelectric power plant with financial losses. 

SABESP  understands  that  the  expectation  for  all  cases  is  of  possible  losses,  and  for  the  time 
being, it is not feasible to estimate the amounts involved, since they were not determined. 
(d)           Agreements  with  reduced  tariffs  with  State  and  Municipal  Government  Entities  that 
joined the Water Rational 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.  

(e)          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.  

(f)           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 2013, 
the  expenses  related  to  personnel  assigned  by  SABESP  to  other  state  government  entities 
amounted to R$12,879 (R$12,298 in December 2012 and R$10,888 in December 2011).  

As  of  December  31,  2013,  expenses  related  to  personnel  assigned  by  other  entities  to  SABESP 
totaled R$695 (R$689 in December 2012 and no expenses were recorded at December 2011).

(k)          Loan agreement through credit facility 

The Company holds interest in certain Special Purpose Entities (SPE), not holding the majority 
interest  but  with  power  of  veto  in  some  issues.  Therefore,  these  SPEs  are  considered  for 
accounting purposes as jointly-owned subsidiaries.

Andradina  S.A.,  Águas  de  Castilho  S.A.  Aquapolo  Ambiental  S.A.  to  finance  the  operations  of

(d)      Intangible arising from concession agreements 

The  Company  operates  concession  agreements  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 exploration of assets related to the public service (See Note 3.8 (a)). A 
general  obligation  also  exists  to  return  the  concession  infrastructure  to  the  concession  grantor  in 
good working condition at the end of the concession. 

As of December 31, 2013 and 2012, the Company operates in 363 municipalities in the State of São 
Paulo. In most of these contracts operations are based on 30-year concession period.

Notes to the Financial Statements 
Years Ended December 31, 2013 and 2012 
Amounts in thousands of reais, unless otherwise indicated  

The services provided by the Company are billed at a price regulated and controlled by the Sanitation 
and Energy Regulatory Agency of the State of São Paulo (ARSESP). 

Intangible rights arising on concession agreements include:  

(i)     Service concession agreements – equity value 

These  refer  to  municipalities  assumed  until  2006,  except  for  the  municipalities  assumed  by 
economic  value  through  assets  valuation  report  prepared  by  independent  experts.  The 
amortization of  assets  is  calculated  according  to  the  straight-line  method,  which  considers  the 
assets useful life. 

(ii)                  Concession agreements – economic value 

From 1999 through 2006, the negotiations for new concessions were conducted on the basis of 
the economic and financial result of the transaction, determined in a valuation report issued by 
independent appraisers.  

The  amount  determined  in  the  related  contract,  after  the  transaction  is  closed  with  the 
municipal authorities, realized through the subscription of the Company's shares or in cash, is 
recorded  as  "concession  agreements"  and  amortized  over  the  period  of  the  related  concession 
(usually 30 years). As of December 31, 2013 and 2012 there were no amounts pending related to 
these payments to the municipalities.  

Intangible  assets  are  amortized  on  a  straight  line  basis  over  the  period  of  the  concession 
agreements or for the useful lives of the underlying assets, whichever is shorter.   

(iii)     Program contracts 

These refer to the renewal of contracts previously referred to as concession agreements whose 
purpose is to provide sanitation services. The amortization of the assets acquired until the dates 
of signatures of the program contracts is calculated according to the straight-line method, which 
considers  the  assets’  useful  lives.  Assets  acquired  or  built  after  the  signature  dates  of  program 
contracts  are  amortized  during  the  contracted  period  (30  years)  or  during  the  useful  lives  of 
underlying assets, whichever is shorter.  

(iv)     Program contracts - Commitments 

After the enactment of the regulatory framework in 2007, renewals of concessions started to be 
made  through  of  program  contracts.  In  some  of  these  program  contracts,  the  Company 
undertook  the  commitment  to  financially  participate  in  social  and  environmental  actions.  The 
assets built and financial commitments assumed within the program contracts are recorded as 
intangible assets and are amortized by the straight-line method in accordance with the duration

On June 23, 2010, the Company entered into an agreement with the State of São Paulo and the 
Municipality of  São  Paulo to  regulate the  provision of  water  and  sewage  services  in  the  city  of 
São Paulo for a 30-year period, which is extendable for an another 30-year period.   

Also on June 23, 2010, an agreement was signed between the state and municipal government, 
and  SABESP  and  the  Sanitation  and  Energy  Regulatory  Agency  of  the  State  of  São  Paulo 
(“ARSESP”) are the consenting and intervening parties, whose main aspects are the following:  

1. The State and the Municipality of São Paulo grant to Sabesp the right to explore the sanitation 
service in the capital of the State of São Paulo, which consists of the obligation to such provide 
service and charge the respective tariff for this service;  

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 SABESP’s operations in the metropolitan region of São 
Paulo;  

4.  All  operational  costs,  taxes,  investments  and  the  opportunity  cost  of  the  investees  and  the 
creditors of Sabesp’s were considered in the cash flow analysis;  

5.  The  agreement  provides  for  investments  established  in  the  agreement  comply  with  the 
minimum  of  13%  of  the  gross  revenue  from  the  municipality  of  São  Paulo,  net  of  the  taxes  on 
revenues.  Investment  plans  referring  to  Sabesp’s  execution  shall  be  compatible  with  the 
activities and programs foreseen in the state, municipal sanitation plans, and where applicable, 
the  metropolitan  plan.  The  investment  plan  is  not  definite  and  will  be  revised  by  Managing 
Committee every four years, especially as to investments to be made in the following 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 and delinquency in the period;  

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; and

8. The agreement considers the recovery of net assets in operation, preferably evaluated through 
equity valuation or carrying amount monetarily restated, as defined by ARSESP. In addition, the 
agreement provides for the remuneration of investments to be made by SABESP, so that there is 
no residual value at the end of the agreement.  

Referring to the recovery through tariff, mentioned in item 6 above, of transfer to the Municipal 
Fund  of  Environmental  Sanitation  and  Infrastructure,  ARSESP  issued  in  April  2013,  the 
Resolution no. 413, postponing the application of Resolution no. 407 until the conclusion of the 
tariff revision process, the transfer to the bill of services of amounts referring to the municipal 
charges which were stipulated in Resolution no. 407. The postponement to apply Resolution no. 
407  was  due  to  a  request  by  the  São  Paulo  State  Government  to  analyze,  among  other  things, 
methods to reduce the impact on consumers. 

The  agreement  represents  51.75%  of  the  total revenue  of  the  Company  on  December  31,  2013, 
and  ensures  the  judicial  and  assets  security,  adequate  return  to  shareholders  and  quality 
services to its customers.

financial  pending  issues  existing  until  the  signature  date  of  the  Agreement  related  to  the 
rendering  of  water  supply  and  sewage  collection  services  to  the  real  properties  of  the

for losses.

eventual administration costs, and the responsibility of the primary risk. In 2013 and 2012 the 
margin was 2.3%.

following projects: ETA Rio Grande, Litoral Norte, Vale do Paraíba and Mantiqueira and Bacia 
do  Piracicaba  -  Capivari  -  Jundiaí  (PCJ),  in  addition  to  supporting  part  of  SABESP’s  losses 
reduction program.   

The  early  amortization,  fully  or  partially,  of  the  subscribed  debentures,  when  authorized  by 
BNDES  and/or  BNDESPAR,  shall  always  occur  jointly,  observing  the  proportionality  between 
the outstanding balances of Series 1, 2 and 3 Debentures of all issues. The agreement does not 
include a premium due to early amortization. 

(ii)             Payments  

Debentures (11th issue) 

On March 1, 2013, the Company fully redeemed the 11th issue of debentures, in the amount of 
R$1,060,428,  R$1,012,500  referring  to  the  principal  and  R$47,928  referring  to  interest  rates 
and premium. 

(iii)           Covenants  

For the outstanding contracts, the Company has the following restrictive clauses “covenants”: 

Applicable to the 10th issue, 14th issue and 18th issue: 

Calculated every quarter, upon the disclosure of interim or annual financial statements: 

- Adjusted Ebitda / Adjusted net operating income: equal or higher than 38%. 
- Adjusted Ebitda / Adjusted financial expenses: equal to or higher than 2.35. 
- Adjusted net debt / Adjusted Ebitda: equal to or lower than 3.65.  

For  these  issues,  in  the  assumption  of  non-compliance  with  the  levels  established  in  the 
Financial  Commitments,  the  Company  shall  within  ninety  (90)  days,  as  of  the  debenture 
holders’ written notice, create additional guarantees, accepted by debenture holders, under the 
penalty of declaring the early maturity of the agreement.  

  
  
  
  
  
  
 
  
   
   
   
   
   
 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
The agreements also have a cross default clause, i.e., the early maturity of any of the Company’s 
debts, the amount of which may anyhow compromise the settlement of its obligations provided 
for in the indenture deed shall imply the early maturity of this agreement.

Notes to the Financial Statements 
Years Ended December 31, 2013 and 2012 
Amounts in thousands of reais, unless otherwise indicated 

Applicable to the 12th issue: 

Calculated every quarter upon the disclosure of interim or annual financial statements: 

-  Adjusted  current  ratio  (current  assets  divided  by  current  liabilities,  excluding  from  current 
liabilities the current portion of noncurrent debts incurred by the Company that are recorded 
in current liabilities) higher than 1.0.  

- EBITDA to paid financial expenses ratio equal to or higher than 1.5.  

Noncompliance  with  these  obligations  only  will  be  characterized  when  verified  in  its  interim 
financial  statements,  during  at  least,  two  consecutive  quarters,  or  also  two  nonconsecutive 
quarters within a twelve-month period.  

In case of noncompliance with the covenants, the trustee should call an extraordinary debenture 
holders'  meeting  within  48  hours  from  the  acknowledgement  of  the  noncompliance  to  resolve 
on the declaration of early maturity of the debentures. 

The  agreements  have  a  cross  default  clause,  i.e.  the  early  maturity  of  any  of  the  Company’s 
debts, equal to or exceeding R$50 million, adjusted by IPCA variation as of the issue date, due to 
contractual  default,  the  amount  of  which  may  anyhow  compromise  the  settlement  of  the 
Company’s  monetary  obligations  arising  from  the  Issue,  shall  imply  the  early  maturity  of  this 
agreement. 

Applicable to the 15th issue, 16th issue and 17th issue: 

Calculated every quarter upon the disclosure of interim or annual financial statements: 

- Adjusted total Debt/Ebitda: lower than or equal to 3.65; and 
- Ebitda/Paid financial expenses: equal to or higher than 1.5. 

Non-compliance  with  the  covenant  clauses,  during,  at  least,  two  consecutive  quarters,  or  also 
two nonconsecutive quarters within a twelve-month period shall result in the early maturity of 
the agreement. 

The  agreements  have  a  cross  default  clause,  i.e.,  the  early  maturity  of  any  of  the  Company’s 
debts, equal to or exceeding R$90 million adjusted by IPCA variation as of the issue date, due to 
contractual  default,  the  amount  of  which  may  compromise  the  settlement  of  the  Company’s 
monetary obligations arising from the Issue.

The reduction of balance under item “Recoverable Taxes” is mainly due to the lower balance of 
income  tax  and  social  contribution  recoverable  in  2013  and  decrease  of  IRRF  provision  on 
financial investments, due to the concentration of investment funds, where half-yearly (May and

The reduction of taxes payable from current liabilities mainly derives from the recovery of 2012 
Cofins and Pasep credit and payment of Paes in the year. 

The  Company  applied  for  enrollment  in  PAES  on  July  15,  2003,  in  accordance  with  Law 
No 10,684  of  May  30,  2003,  and  included  in  its  application  the  debts  related  to  COFINS  and 
PASEP  which  were  involved  in  a  legal  action  challenging  application  of  Law  9718/98,  and  the 
outstanding balance under the Tax Recovery Program (REFIS). The original amount included in 
PAES was R$316,953:  

The tax debt related to PAES (Special Installment Payment) was fully paid in 120 months, the 
last installment of which was paid on June 28, 2013. The amounts paid in 2013, 2012 and 2011 
were R$19,164, R$37,421 and R$36,091, respectively, and financial expenses of R$153, R$1,353 
and 2,761, respectively. There is no outstanding balance as of December 31, 2013. There are no 
restrictions to the assets offered as guarantee in previous REFIS, totaling R$249,034, which still 
guaranteed  the  amounts  in  the  PAES  program,  pursuant  to  the  Law  nº  9532  of  December  10, 
1997, since tax credits included in referred program were extinguished with the payment of final 
installment.

(i)           Permanent difference related to the provision for actuarial liability (Note 9 (vii)). 

(e)      Transition Tax Regime(RTT) 

For the purposes of calculating the income tax and the social contribution related to 2010 and 
2009, the Company opted to adopt the Transition Tax Regime (RTT), which allow eliminate the 
accounting  effects  of  the  Law  11,638/07  and  the  Provisional  Measure  449/08,  converted  into 
Law  No.  11,941/2009,  by  the  registers  in  the  fiscal  books  –  LALUR  and  auxiliary  controls, 
without any modification in the bookkeeping.  

The  Company  has  been  adopting  the  same  tax  practices  since  2008,  as  RTT  started  to  be 
mandatory  and  will  be  effective  until  the  effectiveness  of  law  ruling  the  tax  effects  of  new 
accounting methods, seeking the tax neutrality. 

(f)      Provisional Measure 627/2013 

On November 11, 2013, the Provisional Measure 627 was issued, altering the federal tax laws on 
the  Corporate  Income  Tax  (IRPJ),  Social  Contribution  on  Net  Income  (CSLL),  PIS/PASEP 
Contribution and Contribution of Social Security Financing (Cofins). This Provisional Measure 
revokes  the  Transitory  Tax  Regime  (RTT),  enacted  by  Law  11941/09  and  also  provides  for  the 
taxation  of  legal  entity  domiciled  in  Brazil,  referring  to  the  equity  addition  deriving  from  the 
profit  sharing  earned  abroad  by  subsidiaries  and  associated  companies  and  profit  earned  by 
individual residing in Brazil by means of foreign subsidiary. This provisional measure allows the 
possibility of adopting its effects in the 2014 calendar year. 

The Company prepared a study of potential effects of applying the Provisional Measure 
627/2013 and the Normative Ruling 1,397/2013 and concluded that they do not result in 
relevant effects on its operations and its financial statements for the fiscal year ended December 
31, 2013, based on the best interpretation of current wording of the Provisional Measure. The 
eventual conversion of Provisional Measure 627/2013 into Law may result in altering the 
Company’s conclusion, if the final text results in changes not envisaged in the Provisional 
Measure and altering current taxation to which the Company is subject. The Company is 
awaiting the conversion of referred Provisional Measure into Law, so that it may decide on its 
early adoption or not, as per final wording to be enacted.

 (c)      Explanation on the nature of main classes of lawsuits 

(i)                Customer claims 

Approximately 1,380 lawsuits were filed by commercial customers, which claim that their tariffs 
should  correspond  to  other  consumer  categories,  and  720  lawsuits  which  claim  a  reduction  in 
the  sewage  tariff  due  to  losses  in  the  system,  consequently  requesting  the  refund  of  amounts 
charged  by  the  Company.  The  Company  was  granted  both  favorable  and  unfavorable  final 
decisions  at  several  court  levels  and  recognized  provisions  when  the  chances  of  losses  are 
probable.  The  R$9,640  decrease  in  the  lawsuits  classified  as  probable  loss  (net  of  escrow 
deposits) is mainly related to the payments and lawsuits filed during the year and revisions of 
expectations caused by favorable decisions to the Company in 2013, offset by interest rates, fees 
and  updates  of  lawsuits  in  progress.  These  same  revisions  of  expectations  favorable  to  the 
Company resulted in a decrease of R$124,300 in the lawsuits with expectation of possible losses.  

(ii)             Supplier claims 

Suppliers’  claims  include  lawsuits  filed  by  some  suppliers  alleging  underpayment  of  monetary 
restatements,  withholding  of  amounts  related  to  the  understated  inflation  rates  deriving  from 
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  chances  of 
losses  are  probable.  The  R$41,338  increase  in  lawsuits  whose  likelihood  of  loss  is  considered 
probable  (net  of  escrow  deposits)  is  mainly  related  to  interest,  fees  and  update  of  lawsuits  in 
progress. The R$295,800 increase in lawsuits whose likelihood of loss is considered possible is 
related to an increase in the number of lawsuits filed in 2013, as well as interest rates, fees and 
update of lawsuits in progress. 

(iii)           Other civil claims 

These  mainly  refer  to  indemnities  for  property  damage,  pain  and suffering,  and  loss  of  profits 
allegedly caused to third parties, filed at different court levels, dully accrued when classified as 
probable  losses.  The  R$47,100  decrease,  for  lawsuits  with  probable  chances  of  loss  (net  of 
escrow deposits), was due to payments and lawsuits filed occurred in the year and revisions of 
expectations  caused  by  favorable  decisions  to  the  Company  during  2013.   The  R$60,400 
increase in the lawsuits with expectation of possible losses is related to interest rates, fees and 
update of lawsuits in progress, and an increase in the number of lawsuits filed in 2013. 

(iv)            Tax claims 

Tax claims refer mainly to issues related to tax collections challenged due to differences in the 
interpretation of legislation by the Company's management, accrued when classified as probable 
loss.  The  decrease  of  R$10,382  in  lawsuits  with  expectation  of  probable  losses  (net  of  escrow 
deposits) was due to payments and lawsuits filed during the year and revisions of expectations 
due to favorable decisions to the Company during 2013. The R$79,800 increase in lawsuits with 
chances of possible losses is related to an increase in the number of lawsuits filed in 2013, and 
mainly to the remeasurement deriving from lawsuits filed by the municipality of São Paulo, as 
outlined in item “b” below.

Notes to the Financial Statements 
Years Ended December 31, 2013 and 2012 
Amounts in thousands of reais, unless otherwise indicated 

Main lawsuits are the following: 

(a) In 2006, the Federal Revenue Service, by means of a tax execution, assessed the Company 
referring  to  the  tax  obligations  related  to  income  tax  and  social contribution  for  calendar year 
2001,  and  recognized  taxes  payable  adjusted  through  December  31,  2013  in  the  amount  of 
R$411,890  (R$389,505  in  December  2012).  The  Company  filed  a  timely  objection  and  will 
appeal against the tax assessment at administrative level and in courts. Managements considers 
that  the  likelihood  of  loss  of  this  administrative  proceeding  is  approximately  90%  considered 
remote and 10% possible. 

(b) The municipality of São Paulo through law revoked the services tax exemption which until 
them  the  company  withheld  and  thereafter  issued  tax  deficiency  notices  related  to  the  sewage 
service  and  ancillary  activities,  in  the  updated  amount  of  R$307,817 (R$264,627  in  December 
2012), which currently are subject-matter of Tax Foreclosures, classified by the Management as 
possible  losses.  SABESP  filed  a  writ  of mandamus  against  this  revocation,  which  was  rejected, 
and currently is under phase of appealability of Special and Extraordinary Appeals filed. Writs 
of prevention and actions for annulment were also filed, aiming the suspension of enforceability 
of  credits  and  the  annulment  of tax  deficiency  notices,  as  it  understands  that  notwithstanding 
the  exemption  revocation,  the  sewage  activities  and  ancillary  activities  are  not  included  in  the 
list  of  activities  subject  to  taxation  by  municipality.  The  Company’s  Management  assessed  the 
risk as possible losses. 

(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  was  adjusted 
through  December  31,  2013  and  is  estimated  at  R$50,065  (R$47,498  in  December  2012). 
Management assessed it as 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 monetary restatement over 
the  financial  statements  (Law  8.200/91),  which  was  anticipated  in  1996  due  to  an  injunction, 
after  excluded  by  giving  up  the  process  and  adopted  the  Provisional  Measure  38/02.  The 
Administrative Counsel of Fiscal Resources rejected the credit from 1997. The estimated amount 
is R$43,689 (R$42,403 in December 2012). The Company’s Management 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,  but  others  were  not  part  of  the  referred  agreement,  and 
lawsuit proceeds as usual.  The remaining judicial lawsuits considered as possible and probable 
loss are mainly related to taxes and fines. As of December 31, 2013 the amounts of such judicial 
lawsuits  were  R$13,696   and  R$62,979  (R$23,882  and  R$39,063  in  December  2012, 
respectively.)  

(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$56,118,  and  R$8,659,  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$11,164  and  R$698,  totaling  R$11,862  million.  As  the  Company  obtained  a  partial  favorable 
decision  on  this  matter,  the  Company´s  legal  advisors  believe  likelihood  of  loss  amounts  to 
R$6,999  (R$6,782  in  December  2012)  and  R$1,194  (R$1,157  in  December  2012)  are  possible 
and probable, respectively.

(g) SABESP filed two writs of mandamus pleading the declaration of unconstitutional municipal 
law  that  levies  the  collection  of  taxes  deriving  from  the  use  of  public  areas  in  the  water  and 
sewage network installation for the rendering of basic sanitation public utilities. The first writ of 
mandamus was partially granted relief, but will not have any effect because municipal laws were 
revoked and the second writ of mandamus awaits judgment on the municipality’s appeal, as this 
writ  of  mandamus  was  granted  relief  suspending  the  collection  for  the  use  of  urban  soil  and 
tendering  of  collateral.  The  Management  assessed  the  risk  as  possible  loss,  but  it  was  not 
possible  to  estimate  the  amount  involved,  as  it  would  be  necessary  to  know  the  extension  of 
water  and  sewage  networks  and  other  equipment  installed  in  the  municipality’s  urban  soil 
(public areas), as well as define the amount of related property based on the length applied. 

(v)                Labor claims 

The  Company  is  a  party  to  labor  lawsuits,  involving  issues  such  as  overtime,  shift  schedule, 
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  at 
various court levels, and thus is classified as of probable. The Company recognized a provision 
for  claims  which  likelihood  of  loss  is  considered  probable.  The  R$17,252  decrease  in  lawsuits 
with probable chances of losses (net of escrow deposits) is chiefly due to payment and lawsuits 
filed occurred in 2013. The R$88,700 increase in the lawsuits with possible chances of losses is 
due to the increased number of suits filed in 2013.  

(vi)             Environmental claims 

Environmental  claims  refer  to  several  administrative  proceedings  and  lawsuits  filed  by 
government  entities,  including  Companhia  de  Tecnologia  de  Saneamento  Ambiental  –  Cetesb, 
Public Prosecution Office of the State of São Paulo and others, that aim affirmative and negative 
covenants  and  penalty  is  estimated  due  to  failure  to  comply  in  addition  to  the  imposition  of 
indemnity  due  to  environmental  damages  allegedly  caused  by  the  Company.  The  amounts 
accrued represent the best estimate of the Company at this moment, however, may differ from 
the  amount  to  be  disbursed  as  indemnity  to  alleged  damages,  in  view  of  the  current  stage  of 
referred  proceedings.  The  R$34,264  increase  in  lawsuits  with  expectation  of  probable  losses 
(net  of  escrow  deposits)  is  mainly  related  to  the  complementary  estimates  of  lawsuits  in 
progress. The R$47,600 increase in the lawsuits with possible losses is due to the increase in the 
number of lawsuits filed in 2013 and the complementary estimates of lawsuits in progress. 

Among  the  main  lawsuits  the  Company  is  involved,  there  are  four  public  civil  actions  the 
subject-matters of which are: a) sentence SABESP to restrain itself from discharging or releasing 
sewage  without  due  treatment;  b)  invest  in  the  water  and  sewage  treatment  system  of  the 
municipality, under the penalty of paying a fine; c) payment of indemnity due to environmental 
damages,  amongst  others.  On  December  31,  2013,  Management  classified  part  of  lawsuits  as 
probable  chances  of  losses,  in  the  amount  of  R$158,135  (R$127,514  in  December  2012)  and 
another part as possible losses in the amount of R$124,880 (R$85,081 in December 2012).

During  2013,  the  Company  settled  several  legal  and  administrative  proceedings,  and  most  of 
them  totaled  R$29,460.  Out  of  this  amount,  R$28,692  refer  to  works  and  R$768  refer  to

The Company is party in concessions-related proceedings, cases in which it can lose the right of 
operating  water  supply  and  sewage  collection  services  in  few  municipalities,  among  which  we 
point out: a) the municipality of Cajobi filed action to recover possession against SABESP, which 
was granted relief and maintained the municipality in the possession of water and sewage assets 
and  services,  with  expected  probable  losses;  b)  the  municipality  of  Tarumã  filed  an  ordinary 
action  against  SABESP,  and  the  operation  is  maintained  but  final  decision  is  pending,  with 
expected  possible  losses;  c)  The  Company  filed  an  ordinary  action  against  the  municipality  of 
Santos, the operation is maintained and there is a final decision at the appellate court favorable 
to SABESP, with expected remote losses; d) The Company filed a lawsuit to recover possession 
against  the  municipality  of  Álvares  Florence,  and  appellate  court  decision  was  unfavorable  to 
SABESP; the operation is not maintained with expected probable losses; e) The Company filed 
an  action  to  recover  possession  against  the  municipality  of  Macatuba  aiming  with  injunction 
return  to  the  possession  of  facilities  under  concession,  the  injunction  was  rejected  and  the 
operation is not maintained in the municipality up to this present date, with expected possible 
losses; f) The Company filed an action to recover possession against the municipality of Iperó, 
which was deemed groundless at trial  and appellate courts. Currently, the Company awaits the 
acceptance of appeals, with expectation of probable loss; g) The municipality of Embaúba filed a 
repossession  action  against  SABESP,  pleading  for  injunction  to  keep  it  in  the  possession;  the 
motion was granted relief and complied with on May 20, 2013. The decision was questioned and 
Sabesp  filed  an  interlocutory  appeal  against  the  injunction  decision.  Both  the  repossession 
lawsuit and the injunction decision are pending judgment, with expectation of possible losses.

Notes to the Financial Statements 
Years Ended December 31, 2013 and 2012 
Amounts in thousands of reais, unless otherwise indicated 

The  Company  proposed  dividends  as  interest  on  shareholders'  equity  in  the  amount  of 
R$456,845, corresponding to R$0.6684 per common share,  net of income tax of R$37,758, to 
be resolved on the Shareholders’ Meeting to be held on April 30, 2014. 

The Company declared dividends payable as interest on shareholders’ equity in the amount of 
R$456,845,  which  considers  the  minimum  dividend  amount  set  forth  in  the  Bylaws.  The 
amount  exceeding  the  minimum  mandatory  dividend  due  in  the  year  of  R$80,620  was 
reclassified in equity to the “Additional proposed dividends” account, this amount includes the 
withholding income tax of R$37,758.  

Pursuant  to  CVM  Resolution  nº  207/1996,  the  Company  imputed  interest  on  shareholders’ 
equity  to  the  minimum  dividend  by  its  net  value  of  withholding  income  tax.  The  amount  of 
R$37,758 referring to the withholding income tax was recognized in current liabilities, in order 
to comply with tax liabilities related to the credit of interest on shareholders’ equity. 

The balance payable as of December 31, 2013 was R$456,845, net of withholding income tax. 

(d)         Capital reserve 

The capital reserve includes tax incentives and donations received by the company and may only 
be used for future capital increases.  

(e)          Legal reserve 

Earnings  reserve  -  legal  reserve  is  a  requirement  for  all  Brazilian  corporations  and  represents 
accrual  of  5%  of  annual  net  income  determined  based  on  Brazilian  law,  up  to  20%  of  capital. 
However, we are 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 

Earnings  reserve  -  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 capital budget approved by the Management. 

As of December 31, 2013, 2012 and 2011, the balance of investment reserve totaled R$5,980,535 
, R$4,690,619 and R$3,408,591 , respectively. 

Pursuant to Paragraph four of Article 28 of the by-laws, the Board of Directors may propose to 
the Shareholders’ Meeting that the remaining balance of net income for the year, after deducting 
the legal reserve and minimum mandatory dividends, be allocated to an investment reserve that 
will comply with the following criteria:   

I-                    its  balance,  jointly  with  the  balance  of  the  other  earnings  reserves,  except  for 
reserves for contingencies and realizable profits, may not exceed the capital stock;

The Management will send for approval at the shareholders’ meeting, a proposal to transfer the 
retained earnings balance, in the amount of R$1,289,916 to the Investment Reserve account, in 
order  to  meet  the  investment  needs  foreseen  in  the  Capital  Budget.  In  addition,  it  will  send  a 
proposal to increase capital stock with part of earnings reserves, in the amount of R$ 3,672,057, 
as  this  reserve  exceeds  the  capital  stock  amount  on  December  31,  2013.  In  addition,  it  will 
propose  to  fully  capitalize  the  capital  reserve  by  increasing  capital  stock,  in  the  amount  of 
R$124,255. 

After  capitalizing  part  of  the  earnings  reserve  and  total  capital  reserve  by  increasing  capital 
stock, yet to be approved at the Shareholders’ Meeting, the capital stock will be R$10,000,000. 

(h)      Retained earnings (accumulated losses) 

Retained  earnings  (accumulated  losses):  the  statutory  balance  of  this  account  is  zero  as  all 
retained earnings must be distributed or allocated to an earnings reserve at year end.  

(i)             Other comprehensive income 

Gains and losses arising from changes in the actuarial assumptions are accounted for as other 
comprehensive  income,  net  of  income  tax  and  social  contribution  effects.  See  Note  19  (b),  the 
breakdown of amounts recorded in 2013 and 2012.

Notes to the Financial Statements 
Years Ended December 31, 2013 and 2012 
Amounts in thousands of reais, unless otherwise indicated 

(i)             This  variation  is  mainly  due  to  interest  rates  of  the  Public-Private  Partnership 
agreement  of  Alto  Tietê  Production  System  –  CAB  –  Sistema  Produtor  Alto  Tietê 
S/A, in the amount of R$32,198 in 2013.  

(ii)          The account variation mainly derives from an increase in debt inventory indexed 
to  IPCA  in  view  of  the  17th  Issue  of  Debentures.  This  inflation  adjustment  derives 
from changes in the indexes defined in loan agreements, such as, UPR, IPCA, CDI 
and  TJLP,  corresponding  to  0.2%,  5.9%,  9.8%  and  5.0%,  respectively,  in  2013. 
(0.3%, 5.8%, 6.9% and 5.5%, respectively, in 2012 and 1.2%, 6.5%, 10.9% and 6.0%, 
respectively , in 2011). The exposures to these rates are shown in Note 4.3.1. 

(iii)        This inflation adjustment derives from the change in the National Consumer Price 
Index (INPC) rate of 5.6% in 2013 (6.2% in 2012 and 6.1% in 2011), which is used 
to  adjust  the  balance  of  SABESP’s  commitment  in  relation  to  the  deficit  of  the 
Sabesprev mais pension plan. 

(iv)         Other expenses related to inflation adjustment mainly arises from the adjustment 
of  liabilities  referring  to  investment  commitments  required  by  the  public-private 
partnerships and mainly from program contracts indexed by the IPC and IPCA of 
3.9%  and  5.9%  in  2013  and  5.1%  and  5.8%  in  2012  and  6.4%  and  6.5%  in  2011, 
respectively. 

(v)            These  inflation  adjustments   arise  from  accounts/bills  of  overdue  accounts 
receivable,   which  are  restated  depending  on  the  payment  date,  by  IPCA  (5.9%  in 
2013, 5.8% in 2012 and 6.5% in 2011) or IPC-FIPE (Consumer Price Index, 3.9% in 
2013, 5.1% in 2012 and 5.8% in 2011), and escrow deposits, which are adjusted by 
the  index  defined  by  the  Judiciary  Branch,  which  varied  between  5.6%  in  2013, 
6.0% in 2012 and 6,2% in 2011. 

(vi)          The  variation  is  mainly  due  to  interest  rates  on  agreements  and  installment 

payments. 

(vii)        The  increase  in  foreign  exchange  variation  on  loans  and  financing  mainly  arises 
from  the  14.6%  U.S.  dollar  appreciation  against  the  Brazilian  Real  in  2013,  when 
compared  to  the  8.9%  appreciation  in  2012  (depreciation  of  12.6%  of  the  real 
against the U.S. dollar in 2011).

30          Events after the reporting period 

(a)              Sabesp’s  Incentive Program to Reduce Water Consumption 

After being approved by ARSESP on an emergency basis through Resolution 469/2014, SABESP 
adopted an economic incentive to stimulate households of the Greater São Paulo to reduce water 
consumption. This measure was adopted due to the record heat and the inedited rainless in the 
Cantareira System, which is in a critical level and which supplies almost 10 million people. 

The  clients  who  reduced  by,  at  least,  20%  the  average  consumption  of  a  12-month  period: 
February 2013 to January 2014, will have a 30% discount in their bill. This deduction shall apply 
over  a  lower  amount,  since  decrease  in  consumption  will  result  in  cheaper  bill  to  apply  the 
benefit. 

This  measure  applies  to  households,  commerce  and  industries  supplied  by  Cantareira  System: 
the  entire  north  area  and  São  Paulo  downtown,  part  of  east  and  west  areas  of  the  capital  city, 
Barueri, Caieiras, Carapicuíba, Francisco Morato, Franco da Rocha, Itapevi, Jandira, Osasco and 
Santana de Parnaíba. In Guarulhos and São Caetano do Sul, also served by Cantareira System, 
the distribution is under the local governments’ responsibilities, which buy water from SABESP. 
The municipal services shall decide about the decision of granting this incentive. 

This  benefit  will  be  valid  for  the  bills  in  the  reference  months  from  February  to  August  and 
consumers will receive the bill from March to September. In Santana de Parnaíba, this measure 
shall  apply  in  the  reference  months  from  March  to  August  and  bill  is  delivered  between  April 
and September. 

However,  in  April  2014  the  incentive  program  was  extended  for  the  entire  São  Paulo 
metropolitan  region  until  the  end  of  2014  or  until  the  water  level  in  the  reservoirs  is 
normalized.  As a result of the drought and low water volume in the Cantareira System, the São 
Paulo  State  Department  of  Water  and  Energy  (DAEE)  and  the  National  Water  Agency  (ANA) 
determined that, as of March 10, 2014, we must temporarily restrict the flow of water from the 
Cantareira System from 33 m³/s to 27.9 m³/s.  In order to continue to meet consumer demand 
with a restricted water supply, we are increasing our use of other water systems.  This may lead 
to  an  increase  in  our  costs  to  serve  customers  in  the  São  Paulo  metropolitan  region.   If  the 
situation in the reservoirs affected by the drought does not improve, we may be obligated to take 
more drastic measures.  

(b)              ARSESP Tariff Revision 

ARSESP – Sanitation and Energy Regulatory Agency of the State of São Paulo, by means of its 
Resolution nº 463 of January 9, 2014, altered the schedule for development of phases D2, D3, 
D4  and  D5  of  ARSESP  Resolution  nº  434  of  10/31/2013,  referring  to  SABESP’s  first  Tariff 
Revision  and  defined  as  April  10,  2014  as  the  date  to  publish  the  Initial  Maximum  Price  (P0) 
and  the  definitive  Efficiency  Factor  (X  Factor)  for  the  tariff  cycle  initiated  on  August  11,  2012, 
establishing the following dates for remaining phases: 

i.              Phase  D2  -  ARSESP  releases  the  proposals  for  Initial  Maximum  Price  (P0)  and 
definitive Efficiency Factor (X Factor) and the opening of a public consultation, summoning for 
public hearing on 2/11/2014; 

  
  
  
  
  
  
  
  
  
  
  
  
ii.             Phase  D3  –  Public  hearing  was  held  on  3/12/2014  and closure  of Public Consultation 
postponed for 3/19/2014, as notified at its website; 

iii.           Phase  D4  –  Publication  of  results  related  to  the  Initial  Maximum  Price  (P0)  and 
definitive Efficiency Factor (X Factor) and a substantiated report on contributions to the public 
consultation on 4/10/2014; and 

iv.           Phase D5 – Publication of schedule to define and implement the new Tariff Structure of 
SABESP on 4/10/2014.  

On  April  17,  2014  –  ARSESP  issued  Resolution  No.  484,  which,  among  other  things:  (i) 
establishes  that,  as  of  May  11,  2014,  a  tariff  repositioning  index  of  5.4408%  in  relation  to  our 
current tariffs and an annual Efficiency Factor (X Factor) of 0.9386%, which will be deducted in 
the upcoming annual tariff adjustments, shall be applied to water services bills, (ii) allows us to 
apply  the  repositioning  index  arising  from  the  tariff  revision  at  a  more  opportune  future  date, 
when we shall proceed to recalculate and restate the applicable amounts, in order to ensure our 
economic and financial balance, taking into account the atypical situation in our market due to 
the lack of rainfall and our measures to encourage water savings in order to ensure supply, (iii) 
establishes  that  the  next  annual  tariff  adjustments  will  occur  on  April  11,  2015  and  April  11, 
2016, with the next tariff revision on April 11, 2017, and (iv) ratifies the readjustment rules set 
forth on Resolution No. 406 (described above) and updated the X Factor for the tarif cycle from 
0.836% to  0.9386%.  The current  tariff  structure  will  be  kept  with  respect to our  services until 
the  new  structure  is  approved  by  ARSESP  and  implemented.  Considering  what  has  been 
established by Resolution No. 484, we decided to postpone the application of the repositioning 
index to an opportune date at the end of December 2014, at the latest.

SABESP 

Notes to the Financial Statements 
Years Ended December 31, 2013 and 2012 
Amounts in thousands of reais, unless otherwise indicated 

(c)                 Signature of services agreement with the municipality of Diadema. 

On  March  18,  2014  were  signed  (i)  judicial  settlements  in  lawsuits  filed  by  Sabesp  against  the 
municipality  of  Diadema  and  Saned  –  a  municipal  company,  and  (ii)  a  services  agreement  for 
water  supply  and  sewage  public  utility  services  in  the  municipality  of  Diadema,  30-year 
effectiveness  period  as  of  the  agreement’s  signature  date.  This  agreement  can  be  extended  for 
another 30 years, upon execution of appropriate amendments, under the terms of law. 

ARSESP will authorize the tariffs and will ratify the price table proposed by SABESP, as well as 
it will define the tariff structure, pursuant to the guidelines of Law 11.445/07 and State Decree 
41.446/96  of  the  standards  to  replace  them  and  related  legislation.  As  of  the  date  of  the 
assumption of services by SABESP scheduled to March 31, 2014, the municipality’s tariffs will be 
levelled  to  those  practiced  by  SABESP  in  the  Metropolitan  region  of  São  Paulo,  through  five 
annual real and consecutive adjustments, starting in a period not less than 12 months as of the 
agreement's signature. 

Sabesp shall pay the amount of R$95,000 to the municipality of Diadema to implement actions 
related  to  the  environmental  sanitation  in  the  municipality,  necessary  to  comply  with  the 
universalization targets. These amounts will be paid in two installments of R$47,500, the first 
one  30  days  after  the  agreement’s  signature  and  the  final  installment,  12  months  after  the 
payment  of  the  1st  installment,  and  this  installment  shall  be  adjusted  by  IPC-IBGE.  These 
amounts will be deposited in a specific account, indicated by municipality, which shall be liable 
for the execution of these actions, as well as for the regular accountability, and on a half-yearly 
basis, shall provide a list of actions and related amounts. The amounts, while not used, shall be 
kept  in  financial  investments  and  related  proceeds  only  may  be  used  in  the  execution  of  the 
aforementioned  actions.  These  amounts  shall  be  computed  by  ARSESP  for  the  purposes  of 
determining the agreement’s financial and economic breakeven. 

The  agreement  is  subject  to  ARSESP’s  regulations,  including  referring  to  the  economic  and 
financial breakeven. 

(d)              Program Contracts 

In 2014, the Company renewed its Program Contract of Water Supply and Sewage Services with 
the municipalities of Itapevi, Piedade, Rosana, Lucélia, Parapuã, Jaborandi and Registro. These 
agreements have a 30-year term. 

(e)   Use of reservoirs – EMAE 

In  connection  with  our  lawsuit  regards  to  the  compensation  for  the  use  of  water  from  the 
Guarapiranga and Billings reservoirs requested by Empresa Metropolitana de Águas e Energia 
S.A. (“EMAE”), on April 10, 2014, we issued an Announcement to the Market to communicate 
that  we  are  negotiating  with  EMAE  regarding  a  potential  future  agreement.   However,  no 
adjustment has been confirmed, and no agreement has been executed by either party as of yet.
