OVERVIEW

     California Water Service Group provides water utility services to customers
in California,  Washington, New Mexico, and Hawaii. The majority of the business
is regulated by the respective states public utility  commission.  The Company's
California  water  utility  service  operations  comprise  the  majority  of the
business  and  contributed  96% of revenues  and 83% of net income in 2004.  The
Company also has a regulated  wastewater  business in New Mexico.  Non-regulated
activities relate primarily to the water utility business and include operating,
maintenance, billing, meter reading, and water testing services.

     The regulatory  entities governing the Company's  regulated  operations are
referred to as the Commissions in this report. Revenues,  income, and cash flows
are earned primarily  through  delivering  drinking water through pipes to homes
and  businesses.  Rates  charged to  customers  for the  regulated  business are
determined  by the  Commissions.  These rates are intended to allow  recovery of
operating costs and a reasonable rate of return on capital.

     Major factors  affecting the financial  performance of the Company are: the
process and timing of setting rates charged to customers; weather; water quality
standards;  other regulatory standards;  water supply; quality of water sources;
and level of capital expenditures.



     The most  significant  risk and  challenge to the business  during the past
several years has been obtaining timely rate relief to cover increased costs and
investments.  The  Company  addresses  this risk by having an  experienced  team
dedicated solely to pursuing rate increases and managing Commissions issues. The
business can also be impacted by weather. Weather risk is partially mitigated by
having operations in both northern and southern California,  as well as in three
other  states.  Another  risk  in  the  water  industry  is  obtaining  adequate
financing,  as the capital  expenditures needed for infrastructure  replacements
and improvements may significantly exceed the cash flow generated by operations.
Management  believes that the Company has a strong  balance sheet and is capable
of supporting the financing needs of the business through use of debt and common
stock.  Finally,  the water industry is highly  regulated and must comply with a
multitude of  standards  related to water  quality and  service.  To address the
compliance  issues,  the Company has a highly  trained,  focused  team that uses
state-of-the-art  technology  and works  closely  with  government  agencies  to
monitor water supplies and operations.

     For 2004,  net income was $26.0 million  compared to $19.4 million in 2003,
an increase of 34%.  Diluted  earnings per share for 2004 were $1.46 compared to
$1.21 in 2003,  an increase  of 21%.  The  increase  in  earnings  per share was
primarily  due to  increased  rates,  which were  approved  by the  Commissions.
Partially  offsetting the increased  rates were higher  operating  costs,  lower
gains  from  property  sales,  and the  dilutive  effect of having  more  shares
outstanding.  The Company plans to continue to seek additional rate increases in
future years to recover its  operating  cost  increases  and receive  reasonable
returns on invested  capital.  Due to more stringent water quality standards and
investments   in   infrastructure,   the  Company  plans  to  increase   capital
expenditures  in 2005.  For each of the five years  subsequent to 2005,  capital
expenditures  are expected to be lower compared to 2005, but will remain at much
higher levels than depreciation expense. Cash from operations is not expected to
be  sufficient  to fund the cash  needs of the  Company  (capital  expenditures,
dividends,  and other  cash  needs);  therefore,  the  Company  expects  to fund
anticipated  cash  shortfalls  through a  combination  of debt and common  stock
offerings in the next five years.  In 2004, the Company  received many different
types of rate  increases,  some of which were temporary in nature.  As such, the
high  growth in earnings  in 2004 is not  expected  to be  repeated  in 2005.  A
significant  factor in 2005  earnings  will be the  timing and the amount of the
approved  General Rate Case (GRC) filings  expected to be received in the fourth
quarter of 2005.

BUSINESS

     California  Water  Service  Group  is a  holding  company  incorporated  in
Delaware with five operating subsidiaries: California Water Service Company (Cal
Water),  CWS Utility  Services  (Utility  Services),  New Mexico  Water  Service
Company (New Mexico Water), Washington Water Service Company (Washington Water),
and Hawaii Water Service  Company,  Inc.  (Hawaii Water).  Cal Water, New Mexico
Water,  Washington Water, and Hawaii Water are regulated public  utilities.  The
regulated  utility entities also provide some  non-regulated  services.  Utility
Services provides non-regulated water operations and related services to private
companies and  municipalities.

     California  water  operations  are  conducted  by the Cal Water and Utility
Services  entities and provide  service to 451,785  customers  in 75  California
communities through 26 separate districts.  Of these 26 districts,  24 districts
are regulated  water systems,  which are subject to regulation by the California
Public  Utilities  Commission  (CPUC).  The  other  two  districts,  the City of
Hawthorne and the City of Commerce,  are governed  through their respective city
councils and are considered  non-regulated because they are outside of the CPUCs
jurisdiction.  Their activities are reflected in operating revenue and operating
costs, as the risks and rewards of these  operations are similar to those of the
regulated  activities.  California water operations account for 95% of the total
customers and 96% of the total operating revenue.




     Washington Water provides domestic water service to 15,015 customers in the
Tacoma and Olympia areas.  Washington Waters utility operations are regulated by
the  Washington  Utilities  and  Transportation  Commission.   Washington  Water
accounts for 3% of the total customers and 2% of the total operating revenue.

     New Mexico Water provides  service to 5,835 water and wastewater  customers
in the Belen, Los Lunas,  and Elephant Butte areas in New Mexico.  Its regulated
operations are subject to the  jurisdiction of the New Mexico Public  Regulation
Commission.  New Mexico Water  accounts for 1% of the total  customers and 1% of
the total operating revenue.

     Hawaii Water provides water service to 520 customers on the island of Maui,
including  several  large  resorts  and  condominium  complexes.  Its  regulated
operations  are  subject  to the  jurisdiction  of the Hawaii  Public  Utilities
Commission. Hawaii Water accounts for less than 1% of the total customers and 1%
of the total operating revenue.

     Other non-regulated activities consist primarily of operating water systems
owned by other entities; pro- viding meter reading and billing services; leasing
communication  antenna sites on the  Company's  properties;  operating  recycled
water  systems;  providing  brokerage  services for water rights;  providing lab
services;  and selling  surplus  property.  These  activities are reported below
operating profit on the income statement; therefore, the revenue is not included
in operating revenue.  Due to the variety of services provided and the fact that
the  activities  are  outside  of the  Company's  core  business,  the number of
customers  is not  tracked  for these  non-regulated  activities.  Non-regulated
activities comprised 5% of the total net income in 2004.

     Rates  and   operations   for  regulated   customers  are  subject  to  the
jurisdiction of the respective  states  regulatory  commission.  The Commissions
require  that  water  and  wastewater  rates  for  each  regulated  district  be
independently  determined.  The  Commissions  are  expected to  authorize  rates
sufficient to recover normal operating  expenses and allow the utility to earn a
fair and reasonable return on invested capital.  Rates for the City of Hawthorne
and City of Commerce water systems are  established in accordance with operating
agreements and are subject to ratification by the respective city councils. Fees
for other non-regulated activities are based on contracts negotiated between the
parties.

RESULTS OF OPERATIONS

     Earnings and  Dividends.  Net income in 2004 was $26.0 million  compared to
$19.4  million in 2003 and $19.1  million in 2002.  Diluted  earnings per common
share were $1.46 in 2004, $1.21 in 2003, and $1.25 in 2002. The weighted average
number of common  shares  outstanding  used in the  diluted  earnings  per share
calculation was 17,674,000 in 2004,  15,893,000 in 2003, and 15,185,000 in 2002.
As explained  below, the increase in 2004 earnings per share resulted from these
primary  factors:  receiving rate relief on GRC filings and balancing  accounts;
customer  growth;  and  increased  usage  due to  improved  weather  conditions.
Partially  offsetting these positive factors were: higher purchased water costs;
higher  operating  costs;  decreased  gains from property  sales;  and increased
common shares outstanding.

     At the January 2005 meeting,  the Board of Directors declared the quarterly
dividend,  increasing it for the 38th consecutive year. Dividends have been paid
for 60  consecutive  years.  The annual  dividend paid per common share in 2004,
2003,  and 2002 was $1.130,  $1.125,  and  $1.120,  respectively.  The  dividend
increases were based on projections  that the higher dividend could be sustained
while still providing adequate financial resources and flexibility. Earnings not
paid  as  dividends   are   reinvested  in  the  business  for  the  benefit  of
stockholders. The dividend payout ratio was 77% in 2004, 93% in 2003, and 90% in
2002, an average of 87% over the three-year period.

     Operating  Revenue.  Operating  revenue was $315.6 million,  an increase of
$38.5 million, or 14%, above 2003. Operating revenue in 2003 was $277.1 million,
an increase  of $14.0  million,  or 5%,  above 2002.  The  estimated  sources of
changes in operating revenue were:

     Overall,   temperatures  in  the  Company's service  areas  for  2004  were
comparable to 2003.  Rainfall in the California  service areas in 2004 was lower
in the spring and higher in the fall. For the entire year,  2004 rainfall in the
California  service areas was lower,  which  impacted the Company's revenues and
earnings  positively.  For 2003,  rainfall  was higher  than  2002,  which had a
negative  impact on revenues and earnings.  For Washington  Water service areas,
rainfall was higher in 2004 than in 2003, and 2003 rainfall was lower than 2002.
In addition to the overall  favorable  weather,  2004 revenues  were  positively
impacted compared to 2003 by increases in rates and customer growth.

     The estimated  impact of rate changes  compared to the prior year is listed
in the following table:


Dollars in millions                                             2004     2003

Total rate increases                                           $29.8    $12.6


     The step rates,  Bakersfield Treatment Plant, GRCs, and offset rate changes
are permanent until the next rate filing for the applicable districts. Most step
rates approved in 2004 were effective in January 2004; therefore,  they will not
increase revenues in 2005, assuming similar customer usage. Some step rates were
approved  during  2004 and are  estimated  to  increase  2005  revenues  by $0.4
million,  assuming  similar  usage.  Rate  changes  previously  approved for the
Bakersfield Treatment Plant will have no incremental impact on 2005 revenues due
to the effective dates being January 2004 or prior.  The GRCs that were approved
during 2004 are estimated to increase revenues in 2005 by $2.1 million, assuming
similar usage. The offset filings approved during 2004 are estimated to increase
2005 revenues by $0.5 million, assuming similar usage.




     The balancing account rate surcharges and catch-up  surcharge have specific
termination  dates. The balancing  accounts  termination dates range from one to
three years from the  effective  date.  For 2005,  management  estimates the net
impact to  revenues  from  balancing  accounts  compared  to 2004 will be a $3.2
million increase, assuming similar usage. This estimate incorporates the effects
of balancing  account  surcharges  that will  terminate and  balancing  accounts
approved in 2004. The catch-up surcharge ended in September 2004; therefore, the
impact to 2005  revenue  compared  to 2004 will be a $3.5  million  decrease  to
revenue.

     Effective  January 2005, step rate increases were approved for $4.1 million
on an annual basis.

     See the RATES AND REGULATION section of this report for more information on
regulatory activity occurring in 2003, 2004, and through March 1, 2005.

     The number of customers in 2004 increased by  approximately  6,700,  or 1%,
from  2003  levels.  This  increase  includes  1,700  customers  related  to  an
acquisition  in New  Mexico  completed  in 2004.  In 2003,  customer  growth was
approximately  7,400,  or  2%,  which  included  520  customers  related  to the
acquisition of Kaanapali Water Corporation in Hawaii and 1,100 customers related
to the arrangement with the City of Commerce.

     Water  Production  Expenses.  Water production  expenses,  which consist of
purchased water,  purchased power, and pump taxes,  comprise the largest segment
of total operating costs. Water production costs accounted for 43.5%, 44.2%, and
45.6% of total operating costs in 2004, 2003, and 2002, respectively.  The rates
charged  for  wholesale  water  supplies,   electricity,   and  pump  taxes  are
established  by various  public  agencies.  As such,  these rates are beyond the
Company's control. The table below provides the amount of increases  (decreases)
and percent changes in water production expense during the past two years:


Dollars in millions                2004                            2003

                       ------    ------    ------      ------   ------    ------


     Two of the principal  factors  affecting water production  expenses are the
amount of water  produced  and the  source of the water.  Generally,  water from
wells costs less than water purchased from wholesale suppliers.  The table below
provides  the  amounts,  percentage  change,  and source mix for the  respective
years:

     Purchased  water expenses are affected by changes in quantities  purchased,
supplier prices, and cost differentials  between wholesale suppliers.  For 2004,
the $8.9 million  increase in purchased  water costs was driven by a combination
of increased  wholesale rates charged by wholesale suppliers in the Stockton and
San Francisco Bay-Area districts,  and increases in quantities purchased.  On an
overall   blended   basis,   wholesale   water   rates   increased   5%   on   a
cost-per-million-gallon  basis.  Included in  purchased  water  expenses  was an
additional  adjustment  of $0.9 million,  which  related to the  settlement of a
meter malfunction matter in the Stockton district.  Purchased power expenses are
affected  by water  pumped  from wells,  water  moved  through the  distribution
system, rates charged by electric utility companies, and rate structures applied
for usage  during peak and  non-peak  times of the day or season.  The change in
purchased  power expenses was primarily due to lower rates charged by suppliers,
which were  partially  offset by higher  volume and no credits  received in 2004
compared  to $0.9  million  credits  received  in 2003.  Pump taxes were  higher
primarily  due to  additional  pumping in one district  that has a high pump tax
rate.

     For 2003, the $4.1 million  increase in purchased water costs was primarily
driven by  increased  wholesale  rates  charged by  wholesale  suppliers  in the
Stockton and San Francisco Bay-Area  districts.  Overall,  wholesale water rates
increased 5% on a cost-per-million-gallon basis. Included in purchased water was
an estimate of $0.7 million,  which related to a meter malfunction matter in the
Stockton  district.  The majority of the change in purchased  power  expenses in
2003 was attributable to credits  received from the electric  utility  companies
($0.9 million) and lower quantities of water pumped from wells.  Pump taxes were
lower due to the decrease in well water production.

     Administrative  and General Expenses.  Administrative  and general expenses
include payroll related to  administrative  and general  functions,  all company
benefits  charged to expense  accounts,  insurance  expenses,  legal fees, audit
fees,  regulatory  utility  commissions  expenses,  board of directors fees, and
general corporate expenses.

     During 2004, administrative and general expenses increased $6.1 million, or
15%, compared to 2003. Payroll expenses  increased $1.0 million,  or 13%, due to
the addition of new employees and wage increases.  Employee  benefits  increased
$1.4  million,  due  primarily  to  increases  in  employee/retiree  health-care
expenses of $1.7 million, or 25%. The Company is primarily self-insured but does
have  stop-loss  coverage for very large claims.  The Company  experienced  more
large-dollar claims (claims above $50,000), which was the primary reason for the
increase.  The Company also experienced  higher costs for workers  compensation,
general liability  claims,  and insurance  premiums.  These costs increased $1.3
million, or 40%. Higher expenses were incurred to comply with the Sarbanes-Oxley
Act, section 404 on internal controls,  which increased expenses by $0.9 million
for consultants and auditors. Fees to the CPUC increased $0.5 million due to the
increased  revenue,  as these fees are  calculated  as a percentage  of revenue.
Other expense elements  contributed to the balance of the change,  but none were
individually significant.

     During 2003, administrative and general expenses increased $3.8 million, or
10%, compared to 2002.  Payroll expenses  increased $0.6 million,  or 9%, due to
the addition of new employees and wage increases.  Employee  benefits  increased
$3.0 million,  due  primarily to increases in  retirement  plan expenses of $2.3
million, or 51%, and  employee/retiree  health-care expenses of $0.4 million, or
7%.  The  retirement  plan cost  increase  was due  primarily  to changes in the
pension plan effective January 1, 2003, which improved benefits to employees. As
part of the  negotiations  with the unions,  lower pay increases  were offset by
increased pension benefits. Other expense elements contributed to the balance of
the change, but none were individually significant.



     Other  Operations  Expenses.  The components of other  operations  expenses
include  payroll,  material  and  supplies,  and  contractor  costs  related  to
operating  water  systems.   This  includes  the  costs  associated  with  water
transmission and distribution,  pumping, water quality, meter reading,  billing,
and operations of district offices.

     For 2004,  other  operating  expenses  increased $2.5 million,  or 7%, from
2003.  Payroll costs charged to other operating expenses increased $1.3 million,
or 6%, due to general wage increases and an increase in the number of employees.
Labor  increases  were in water  quality,  transmission  and  distribution,  and
customer service  categories.  Other major cost increases were operations of the
Bakersfield  Treatment Plant of $0.6 million and additional rent of $0.4 million
for the City of Commerce  operation.  Other expense elements  contributed to the
balance of the change, but none were individually significant.

     For 2003,  other operating  expenses  increased $3.4 million,  or 10%, from
2002.  Payroll costs charged to other operating expenses increased $1.1 million,
or 6%, due to general wage increases, labor related to the Bakersfield Treatment
Plant,  and labor related to customer service in district  offices.  Other major
cost increases were related to lab expenses of $0.5 million,  or 56%;  chemicals
and filters of $0.5  million,  or 42%;  uncollectible  account  expenses of $0.4
million,  or 73%;  and rent  expenses of $0.4  million,  or 45%.  Other  expense
elements  contributed to the balance of the change,  but none were  individually
significant.

     Maintenance.  Maintenance  expenses increased $0.5 million,  or 4%, in 2004
compared to 2003. For 2003, maintenance expenses increased $1.1 million, or 10%,
compared to 2002.  The  variance  was caused by a variety of  factors.  In 2004,
expenses  increased  primarily for service lines, which are pipes from the mains
to the meter  boxes.  In 2003,  more  repairs  were needed  related to leaks and
breaks in both mains and service  lines.  Also, the Company  incurred  increased
maintenance  expenses  for pumps,  and $0.2  million was  expended on a well and
treatment plant in Hawthorne.

     Depreciation and Amortization.  Depreciation and amortization increased due
to the level of  Company-funded  capital  expenditures.  See the  LIQUIDITY  AND
CAPITAL RESOURCES section for more information.

     Property and Other Taxes. For 2004, expenses increased $1.0 million, or 9%,
compared to 2003. For 2003,  expenses increased $0.7 million,  or 7 %. Increased
property  taxes  were  the  primary  cause  for  the  increase  in  both  years.

     Non-Regulated Income, Net. The major components of non-regulated income are
revenue and operating  expenses related to the following  activities:  operating
and maintenance  services (O&M), meter reading and billing services,  leases for
cellular phone antennas,  water rights  brokering,  and design and  construction
services.  For 2004,  non-regulated  income  increased $0.3 million  compared to
2003,  with  increases  primarily from meter reading and billing  services,  and
reduced expenses related to business development. For 2003, non-regulated income
was  relatively  flat compared to 2002,  with  increases  primarily from O&M and
cellular phone antennas  offset by decreases in water rights  brokerage  income.
Water   rights   brokerage   income  is  sporadic  and  is  affected  by  market
opportunities and price volatility. See Footnote 3 of the Consolidated Financial
Statements  for  additional  information.

     Gain on Sale of Surplus  Property.  For 2004, there were minimal gains from
surplus  property sales.  For 2003 and 2002,  pretax gains from surplus property
sales were $4.6  million  and $3.0  million,  respectively.  The 2003 gains were
primarily from three properties sold in the San Francisco Bay Area. Earnings and
cash flow from these  transactions  are  sporadic and may or may not continue in
future periods depending upon market  conditions and other factors.  The Company
has other  surplus  properties  that may be marketed in the future based on real
estate market conditions.



     Interest  Expenses.  Interest  expenses  increased in 2004 and 2003 by $0.3
million,  or 2%, and $0.7 million, or 4%,  respectively.  For 2004, the interest
expense increase was primarily due to lower capitalized interest,  which reduces
net interest expenses.  Partially  offsetting this increase was reduced interest
expense from lesser  amounts of short-term  borrowings.  For 2003, the increased
expense was due  primarily to higher  borrowing of long-term  debt.  Refinancing
activities and lower  short-term  interest rates partially  offset the increase.
See the LIQUIDITY AND CAPITAL RESOURCES section for more information.

RATES AND REGULATIONS

     Following are  summaries of approved and pending rate filings.  The amounts
reported  are annual  amounts;  therefore,  the impact to recorded  revenue will
normally be recognized  over a 12-month  period from the  effective  date of the
decision.  Most increases are permanent  until the next rate filing,  except for
the  increases  related  to the 2001 GRC  catch-up  and the  balancing  accounts
(offsetable expenses), which have specific time frames for recovery.

     2004  Regulatory  Activity  Approved  Filings.In  2004,  Cal Water received
approval  from the CPUC for step rate  increases  of $4.4  million  on an annual
basis,  of which $3.9 million was effective in January 2004 and $0.5 million was
effective  in April 2004.  Step  increases  allow  recovery  of cost  increases,
primarily  from  inflation,  between GRC filings.  GRC filings are normally made
every three years for each Cal Water district.

     In February 2004, the CPUC authorized an advice letter for $0.7 million for
the Stockton  district  related to  increased  purchased  water rates.  The rate
change was effective in February 2004.

     In April 2004, Cal Water received  authorization  from the CPUC on its 2002
GRC. The GRC included  four  districts  and  increased  rates $3.6 million on an
annual basis, effective April 2004.

     In May  2004,  Cal Water  received  approval  from the CPUC to refund  $1.5
million in rates, effective May 2004, which relates primarily to over-collection
of specific expenses incurred over multiple years in the King City and Dominguez
districts. The refunds will primarily occur over a 12-month period, with a minor
amount occurring over a 36-month period.

     In June 2004, Cal Water received approval from the CPUC to recover in rates
$0.4 million in balancing  accounts,  effective  June 2004.  This amount relates
primarily to  recoverable  expenses  incurred in 2001 for the Salinas  district.
This amount will be recovered over a two-year period.

     In July 2004, Cal Water received authorization from the CPUC on its Salinas
district  2001 filing,  which  increased  rates $1.1 million on an annual basis,
effective July 2004.

     In August 2004,  Cal Water  received  authorization  from the CPUC for step
rate  increases for four  districts,  which  increased  rates $0.5 million on an
annual basis, effective August 2004.

     In September  2004, Cal Water received  authorization  from the CPUC on its
2003 GRC filing for the South San Francisco  and  Bakersfield  districts,  which
increased rates a net $0.4 million on an annual basis, effective October 2004.

     In September  2004, Cal Water received  authorization  from the CPUC on its
Los Altos advice letter filing related to purchased water and pump taxes,  which
increased rates $0.5 million on an annual basis, effective October 2004.

     In the October-December  2004 period, Cal Water received  authorization for
recovery of $9.2 million in balancing accounts, which will be collected over one
to  three  years  varying  by  district.   These  amounts  relate  primarily  to
recoverable  expenses  incurred  in 2002  and 2003 for  several  districts.  The
effective dates range from October 2004 to January 2005.

     No filings  were  approved  during 2004 for  Washington  Water,  New Mexico
Water, or Hawaii Water.



     2003  Regulatory  Activity  Approved  Filings.In  January  2003,  Cal Water
received approval for step rate increases totaling $2.2 million.

     In April 2003, the CPUC authorized a second advice letter filing related to
the new Bakersfield  Treatment Plant.  This advice letter allowed an increase in
rates of $1.8 million on an annual basis for the plant, which became operational
in the second quarter of 2003 and had a total project cost of approximately  $50
million.

     In May 2003, the CPUC  authorized the recovery of $5.4 million in balancing
accounts,  of which  approximately  $3.6  million  was  collected  from May 2003
through May 2004,  and  approximately  $1.8 million is being  collected from May
2004 through May 2005.  Partially  offsetting  this  increase was a $0.8 million
decrease for one district that was effective from June 2003 through June 2004.

     In September  2003,  the CPUC  approved  Cal Waters 2001 GRC  applications.
These  filings were  submitted  in July 2001 for 14 of Cal Waters 24  California
regulated  districts.  This GRC decision  authorized an 8.9% return on rate base
and added an estimated $12.8 million to annual revenues. In addition,  Cal Water
received  approval to collect an  additional  $4.5  million in revenues  over 12
months  to  reflect  an  effective  date of  April  3,  2003.  The 2001 GRC also
authorized the filing of step rate increases for $2.7 million  annually for 2004
and 2005 that are  effective  in January of each year  pending  approval  by the
CPUC.

     In the  September-December  2003  period,  the CPUC  approved  increases to
recover  higher  purchased  water  costs  for Cal  Waters  districts  in the San
Francisco Bay Area. The total annual amount of these filings is $4.8 million.

     In October 2003,  the CPUC  authorized a third advice letter filing related
to the Bakersfield  Treatment  Plant.  This allowed an increase in rates of $4.2
million on an annual basis. Due to depreciation  expense for the plant beginning
in January  2004,  only $0.4  million  was billed in the  October-December  2003
period.  The full $4.2 million  annual  amount was effective in January 2004.

     No filings  were  approved  during 2003 for  Washington  Water,  New Mexico
Water, or Hawaii Water.

     Balancing  Accounts,   Offsetable  Expenses,  and  Memorandum  Accounts.The
following  discussion  relates  to changes in the  Company's  expense  balancing
memorandum  accounts (see Expense  Balancing and Memorandum  Accounts section in
CRITICAL ACCOUNTING POLICIES).

     Remaining   Balances   from   Previously   Authorized   Balancing   Account
Recoveries/Refunds.For  the balancing  accounts  authorized in May 2003, the net
amount  remaining to be collected in rates was $0.6 million as of December  2004
and $2.8 million as of December 2003. The balance is expected to be recovered by
May 2005.

     For the balancing accounts  authorized in May 2004, the amount remaining to
be refunded as of December 2004 was $0.6 million.  The balance is expected to be
primarily refunded by May 2005 and the remainder refunded by May 2007.

     For the balancing accounts authorized in June 2004, the amount remaining to
be  collected  in rates as of  December  2004 was $0.3  million.  The balance is
expected to be recovered by June 2006.

     For the balancing accounts authorized in the October-December  2004 period,
the net amount  remaining to be collected in rates as of December  2004 was $8.3
million. The net balance is expected to be fully recovered by January 2008.

     2005 Regulatory  Activity Approved Filings through March 1, 2005.In January
2005, Cal Water received  approval from the CPUC for step rate increases of $4.1
million on an annual  basis,  which were  effective  in  January  2005.

     Pending  Filings as of March 1, 2005.  Cal Water has  pending  its 2004 GRC
filings covering eight districts.  The amount requested is $26.5 million,  which
may  change  due to a variety of  factors.  Over the past few years,  the amount
approved by the CPUC has been  substantially less than the requested amount. The
Company is unable to predict  the  timing and final  amount of these  filings at
this time.



     New Mexico Water has submitted a rate filing for its wastewater operations,
and Hawaii  Water has  submitted  a rate filing for its water  operations.  When
approved,  these filings are not expected to materially affect the total Company
results.  The Company is unable to predict the timing and final  amount of these
filings at this time.  Washington  Water is  planning to submit a rate filing in
2005, but has not filed as of the date of this report.

     Failure to Report  Acquisitions.  In  February  2003,  the CPUCs  Office of
Ratepayer  Advocates  (ORA), a division of the CPUC responsible for representing
ratepayers,  recommended  that Cal Water be fined up to $9.6  million and refund
$0.5 million in revenue for failing to report three  acquisitions as required by
the CPUC.  One  acquisition  was  completed  prior to adoption of the  reporting
requirement  by the CPUC;  the others  were  inadvertently  not  reported by Cal
Water. In July 2004, the CPUC issued  decision D. 04-07-033,  in which Cal Water
was assessed a fine of $75,000 and a reduction of 50 basis points  (0.5%) in the
allowed  return on equity for its Salinas  district,  the district that included
two of the three  acquisitions.  The  reduction in the allowed  return on equity
will be  terminated  upon CPUC  approval  of the next GRC filing for the Salinas
district, which is expected in the fourth quarter of 2005. Cal Water declined to
appeal the decision.

     Review of  Property  Sales by  CPUC.In  1995,  the  California  Legislature
enacted the Water Utility Infrastructure Improvement Act of 1995 (Infrastructure
Act) to encourage  water  utilities to sell surplus  properties  and reinvest in
needed water utility  facilities.  In September  2003, the CPUC issued  decision
D.03-09-021 in Cal Waters 2001 GRC filing.  In this  decision,  the CPUC ordered
Cal Water to file an  application  setting up an  Infrastructure  Act memorandum
account with an up-to-date  accounting of all real property that was at any time
in rate  base and that  Cal  Water  had sold  since  the  effective  date of the
Infrastructure Act. Additionally, the decision directed the CPUC staff to file a
detailed  report on its review of Cal Waters  application.  On January 11, 2005,
the ORA issued a report  expressing  its  opinion  that Cal Water had not proven
that  surplus  properties  sold since 1996 were no longer used and  useful.  ORA
recommended  that Cal Water be fined $160,000 and that gains from property sales
should generally benefit  ratepayers.  Management  strongly  disagrees with ORAs
conclusions  and  recommendations.

     During the period under review,  Cal Waters  cumulative  gains from surplus
property sales were $19.2 million,  which included an inter-company gain related
to a  transaction  with Utility  Services and a like-kind  exchange with a third
party.  If the CPUC finds any surplus  property  sale or transfer  was  recorded
inappropriately, Cal Waters rate base could be reduced, which would lower future
revenues, net income, and cash flows.  Management believes it has fully complied
with the  Infrastructure Act and that ORAs conclusions and  recommendations  are
without   merit.   Cal  Water  intends  to  vigorously   oppose  ORAs  findings.
Accordingly,  Cal Water has not accrued a liability in the financial  statements
for ORAs recommendations.  At this time, Cal Water does not know when or how the
CPUC will rule in this matter.

WATER SUPPLY

     The  Company's  source of supply  varies  among  its  operating  districts.
Certain districts obtain all of their supply from wells; some districts purchase
all of their supply from wholesale suppliers;  and other districts obtain supply
from a combination of wells and wholesale  suppliers.  A small portion of supply
comes  from  surface  sources  and  is  processed  through  Company-owned  water
treatment plants. The Company is meeting water quality, environmental, and other
regulatory standards.



     California's  normal weather  pattern yields little  precipitation  between
mid-spring and mid-fall.  The Washington service areas receive  precipitation in
all seasons,  with the heaviest amounts during the winter.  New Mexicos rainfall
is  heaviest  in  the  summer  monsoon  season.  Hawaii  receives  precipitation
throughout the year, with the largest amounts in the winter months.  Water usage
in all service areas is highest  during the warm and dry summers and declines in
the cool  winter  months.  Rain and snow  during  the  winter  months  replenish
underground  water aquifers and fill reservoirs,  providing the water supply for
subsequent  delivery  to  customers.  To date,  snow  and  rainfall  during  the
2004-2005  water year have been above average.  Precipitation  in the prior five
years was near normal levels. Water storage in Californias reservoirs at the end
of 2004 was at average levels.  Management  believes that the supply pumped from
underground  aquifers and purchased from wholesale suppliers will be adequate to
meet customer  demand during 2005 and beyond.  Long-term  water supply plans are
developed  for each of the Company's districts to help assure an adequate  water
supply under various operating and supply conditions. Some districts have unique
challenges in meeting  water quality  standards,  but  management  believes that
supplies will meet current  standards  using current  treatment  processes.  The
Company is executing a plan to meet a more  stringent  EPA standard for arsenic,
which will become effective in January 2006.


LIQUIDITY AND CAPITAL RESOURCES

     Short-Term  Financing.  Short-term  liquidity  is provided by bank lines of
credit and  internally  generated  funds.  Long-term  financing is  accomplished
through use of both debt and common stock.  Short-term bank borrowings were zero
at  December  31,  2004 and $6.5  million at December  31,  2003.  Cash and cash
equivalents were $18.8 million at December 31, 2004 and $2.9 million at December
31,  2003.  In  addition,  the Company  expects to receive  $7.2  million in tax
refunds in 2005, which will not impact net income.  Given the Company's  ability
to access its lines of credit on a daily  basis,  cash  balances  are managed to
levels  required for daily cash needs and excess cash is invested in  short-term
instruments.  Minimal  operating  levels of cash are  maintained  for Washington
Water, New Mexico Water, and Hawaii Water.

     The water  business is seasonal.  Revenue is lower in the cool,  wet winter
months  when less water is used  compared  to the warm,  dry summer  months when
water  use is  higher.  During  the  winter  period,  the  need  for  short-term
borrowings under the bank lines of credit  increases.  The increase in cash flow
during the summer  allows  short-term  borrowings to be paid down. In years when
more  than  normal  precipitation  falls  in  the  Company's  service  areas  or
temperatures  are lower than normal,  especially in the summer months,  customer
water usage can be lower than normal.  The reduction in water usage reduces cash
flow from operations and increases the need for short-term bank  borrowings.  In
addition,  short-term  borrowings are used to finance capital expenditures until
long-term financing is arranged.

     Cal  Water  has a $45  million  credit  facility.  The term of the  current
agreement  expires in April 2007.  The agreement  requires a 30-day  out-of-debt
consecutive  period  during  any 24  consecutive  months and a  requirement  for
outstanding  balances to be below $10 million  for a 30-day  consecutive  period
during any 12-consecutive-month period. In addition, the agreement requires debt
as a percent of total  capitalization  to be less than 67%.  The Company has met
all covenant requirements. In addition to borrowings, the credit facility allows
for letters of credit up to $10 million. One letter of credit was outstanding at
December 31, 2004 for $0.5 million related to an insurance policy, which reduces
the amount available to borrow. Interest is charged on a variable basis and fees
are  charged  for  unused  amounts.  As of  December  31,  2004,  there  were no
borrowings against the credit facility.



     A $10 million credit  facility  exists for California  Water Service Group,
CWS Utility Services, Washington Water Service Company, New Mexico Water Service
Company,  and  Hawaii  Water  Service  Company,  Inc.  The  term of the  current
agreement  expires in April 2007.  The agreement  requires a 30-day  out-of-debt
consecutive  period  during  any 24  consecutive  months and a  requirement  for
outstanding  balances  to be below $5 million  for a 30-day  consecutive  period
during any 12-consecutive-month period. In addition, the agreement requires debt
as a percent of total  capitalization  to be less than 67%.  The Company has met
all covenant requirements. In addition to borrowings, the credit facility allows
for letters of credit up to $5 million,  which would reduce the amount available
to borrow. No letters of credit were outstanding at December 31, 2004.  Interest
is charged on a variable  basis and fees are charged for unused  amounts.  As of
December 31, 2004, there were no borrowings against the credit facility.

     Generally,  short-term  borrowings used for capital  expenditures  are paid
down through the issuance of long-term debt or issuance of common stock.

     Credit  Ratings.  Cal  Waters  first  mortgage  bonds  are  rated by Moodys
Investors Service (Moodys) and Standard & Poors (S&P). Previously, the two major
credit facility  agreements  contained  covenants related to these debt ratings.
The current  agreements do not contain such covenants.  During 2004,  management
met separately  with the two credit rating  agencies  during their annual rating
reviews. Both agencies maintain their ratings of A2 for Moodys and A+ for S&P as
of the filing date of this  report.  The last time  ratings  were changed was in
February  2004,  when Moodys issued a report  lowering Cal Waters senior secured
debt from A1 to A2 and  characterizing  the rating as stable.  In November 2003,
S&P did not change its rating of A+, but  changed  its  outlook  from  stable to
negative.  Although  the  Company's  financial  performance  and  capitalization
structure  improved  in 2004  compared  to 2003,  which was  recognized  by both
agencies,  they noted concerns related to the rate-setting process and decisions
by the CPUC.  Also,  concerns were raised about the  Company's  level of capital
expenditures,  which  will  need  to be  partially  financed  through  long-term
borrowings or common stock offerings.  Management  believes the Company would be
able to meet  financing  needs even if  ratings  were  downgraded,  but a rating
change may result in a higher interest rate on new debt.

     Long-Term  Financing.  Long-term  financing,  which includes  senior notes,
other debt  securities,  and common stock,  has been used to replace  short-term
borrowings and fund capital  expenditures.  Internally  generated  funds,  after
making  dividend  payments,  provide  positive cash flow, but have not been at a
level to meet all of the Company's capital expenditure needs. Management expects
this trend to continue  given the Company's  capital  expenditures  plan for the
next five years.  In  addition  to  Company-funded  capital  expenditures,  some
capital   expenditures  are  funded  by  developers   contributions  in  aid  of
construction, which are not refundable, and advances for construction, which are
refundable.  Management  believes  long-term  financing is available to meet the
Company's cash flow needs through issuances in both debt and equity markets.

     On June 24, 2004,  the Company  announced  the sale of 1,250,000  shares of
common stock. A prospectus  supplement  and  prospectus  were filed with the SEC
under rule 424 (b) (2) on that date.  The shares  were sold at $27.25 per share.
After the underwriters  exercised their over-allotment  option, the total number
of shares issued was 1,409,700  shares.  The net proceeds were $36.8 million and
the  transaction  was closed on June 29,  2004.  The funds were used to pay down
short-term  borrowings and invest in short-term money market instruments pending
their use for general corporate purposes.  After issuance of these shares, $35.6
million remains in securities under the Company's shelf  registration,  which is
available for future issuance.



     In September 2004, the CPUC issued a decision  granting Cal Water authority
to  complete  up to $250  million of equity  and debt  financing  through  2010,
subject to certain  restrictions.  No financing  has been  applied  against this
authorization as of December 31, 2004. The prior authorization  expired with the
approval of the September  2004  decision.

     In  November   2004,  New  Mexico  Water  entered  into  a  long-term  debt
arrangement for $3.4 million. The interest rate is 5.65%, the loan terminates in
May 2014, and principal  payments are required  during the term of the loan. The
funds  were used to  retire  debt of $2.3  million,  fund an  acquisition,  fund
capital expenditures, and for general corporate purposes.

     Washington  Water has long-term  debt  primarily from two banks to meet its
operating  and  capital  equipment  purchase   requirements  at  interest  rates
negotiated with the banks.  Washington Water did not incur additional  long-term
debt in 2004. Both  Washington  Water and Hawaii Water have  inter-company  debt
with the holding  company,  which is eliminated at  consolidation.  Hawaii Water
does not have any debt with third parties.

     During 2003,  additional long-term debt was issued as part of a refinancing
program that began in 2002.  In May 2003,  Cal Water issued $10 million,  5.54%,
20-year  Series I Senior Notes and $10 million,  5.44%,  15-year Series J Senior
Notes.  Both notes were unsecured.  The proceeds from these borrowings were used
to prepay First  Mortgage Bonds Series EE that had an interest rate of 7.9%. The
principal,  call premiums, and transaction costs were approximately $20 million.
In October 2003, Cal Water issued a $20 million, 5.55% Series N Senior Note. The
note is unsecured  and matures on December 1, 2013.  Payment of principal is due
at maturity.  Funds received were used to prepay First Mortgage Bonds Series FF,
which accrued  interest at a rate of 6.95% and had a principal  balance of $19.1
million. In addition to the prepayment of the principal balance, funds were used
to pay a call premium related to Series FF and transaction costs and for general
corporate  purposes.  In November  2003,  Cal Water issued a $20 million,  5.52%
Series M Senior  Note.  The note is  unsecured  and matures on November 1, 2013.
Payment of  principal  is due at maturity.  Funds  received  were used to prepay
First  Mortgage  Bonds Series GG, which accrued  interest at a rate of 6.98% and
had a principal  balance of $19.1 million.  In addition to the prepayment of the
principal  balance,  funds were used to pay a call premium  related to Series GG
and transaction costs and for general corporate purposes.

     In 2003, incremental long-term financing was provided by issuance of senior
notes by Cal Water  and  common  equity by  California  Water  Service  Group as
detailed below.

     In February 2003, Cal Water  completed the issuance of $10 million,  4.58%,
7-year  Series K Senior Notes and $10 million,  5.48%,  15-year  Series L Senior
Notes. Both notes were unsecured.  The proceeds were used to pay down short-term
borrowings and to fund capital expenditures.

     On July 11, 2003, a shelf registration became effective, which provides for
the issuance from time to time of up to $120 million in common stock,  preferred
stock,  and/or  debt  securities.  The  Company  may issue any of these types of
securities  until  the  amount  registered  is  exhausted,  and will add the net
proceeds  from the sale of the  securities  to its general  funds to be used for
general  corporate  purposes,  which may  include  investment  in  subsidiaries,
working  capital,  capital  expenditures,  repayment of  short-term  borrowings,
refinancing  of  existing  long-term  debt,  acquisitions,  and  other  business
opportunities.

     On August 4, 2003, the Company issued 1,750,000 shares of common stock from
the shelf registration  statement.  A prospectus  supplement and prospectus were
filed  with the SEC under Rule 424 (b) (2) on August 5,  2003.  The shares  were
sold  at  $26.25  per  share.  The  net  proceeds  were  $43.8  million  and the
transaction  was  closed  on  August 7,  2003.  The funds  were used to pay down
short-term  borrowings  and to invest in  short-term  money  market  instruments
pending their use for general corporate purposes.

     The Company does not utilize off-balance-sheet financing or utilize special
purpose  entity  arrangements  for  financing.  The Company does not have equity
ownership through joint ventures or partnership arrangements.


     Additional  information regarding the bank borrowings and long-term debt is
presented in Footnotes 8 and 9 in the Consolidated Financial Statements.

     Dividend Reinvestment and Stock Purchase Plan. The Company's transfer agent
offers  stockholders  a Dividend  Reinvestment  and Stock  Purchase Plan (Plan).
Under the Plan,  stockholders  may  reinvest  dividends  to purchase  additional
Company  common stock without  commission  fees.  The Plan also allows  existing
stockholders  and other  interested  investors to purchase  Company common stock
without  brokerage  fees through the transfer  agent up to certain  limits.  The
transfer  agent  operates  the Plan and  purchases  shares on the open market to
provide shares for the Plan.

     2005 Financing  Plan.  The Company's  2005 financing plan includes  raising
approximately  $20-$40  million of new capital.  The plan  includes  issuance of
long-term  debt to meet funding needs.  Currently,  the Company does not plan to
issue additional  common stock in 2005,  although this may change depending on a
variety of  factors.  Beyond  2005,  management  intends to fund  capital  needs
through a relatively balanced approach between long-term debt and common stock.

     Contractual   Obligations.   The  Company's  contractual   obligations  are
summarized in the table below.  Long-term  debt payments  include annual sinking
fund payments on first mortgage bonds,  maturities of long-term debt, and annual
payments on other long-term  obligations.  Advances for  construction  represent
annual contract  refunds to developers for the cost of water systems paid for by
the  developers.  The  contracts  are  non-interest  bearing,  and  refunds  are
generally on a straight-line  basis over a 40-year period.  Operating leases are
generally  rents for office  space.  The total amount  presented  for  operating
leases is for a 20-year period.

     Cal Water has water supply contracts with wholesale  suppliers in 16 of its
operating districts.  For each contract, the cost of water is established by the
wholesale  supplier and is generally  beyond the Company's  control.  The amount
paid annually to the wholesale  suppliers is charged to purchased  water expense
on the  statement  of income.  Most  contracts  do not  require  minimum  annual
payments and vary with the volume of water purchased.

     The  Company  has  two  material  contracts,  one in Los  Altos  and one in
Bakersfield,  which contain minimal  purchase  provisions  (take or pay).  These
contract  payments  vary with the volume of water  purchased  above the  minimal
levels.  Management  plans to continue to purchase  and use at least the minimum
water  requirement  under these  contracts in the future.  Both contracts  renew
annually. Obligations were estimated assuming a five-year horizon beyond 2004.

     The wholesale  water contract with Stockton East Water District (SEWD) is a
fixed-fee  contract.  The SEWD payments,  excluding  payments related to a prior
year meter issue,  will total $3.7 million  covering  SEWDs fiscal year of April
2004 to March 2005. Payments are made monthly.  Management  estimates the annual
price to increase $0.9 million for the SEWD contract  effective  April 2005, and
management  intends to apply for rate relief for this  increase.  Management  is
unable to estimate price changes beyond a one-year period. SEWD payments are not
included in the above table.

     Capital  Requirements.   Capital  requirements  consist  primarily  of  new
construction  expenditures for expanding and replacing  utility plant facilities
and the acquisition of water systems.  They also include refunds of advances for
construction.



     Company-funded   utility  plant  expenditures  were  $50.4  million,  $53.9
million,  and $71.6  million  in 2004,  2003,  and 2002,  respectively.  A major
project  during this time frame was the $50 million  water  treatment  plant and
related  water   transmission   and   distribution   pipelines  in  Bakersfield,
California.  Expenditures  to construct the plant were incurred over a five-year
period,  with the largest  portion,  $27.1 million,  incurred in 2002. The plant
became operational in 2003. Other major components of capital  expenditures were
mains and water treatment equipment.

     For 2005, Company-funded capital expenditures are budgeted at approximately
$85 million.  The increase in 2005 is primarily  related to compliance  with the
new arsenic standard  effective in January 2006. For years beyond 2005,  capital
expenditures  are estimated at $70-$80  million per year for the next five years
and will be primarily for mains, related water distribution equipment,  pumping,
and water quality  equipment.

     Other  capital  expenditures  are funded  through  developer  advances  and
contributions  in  aid of  construction  (non-company-funded).  The  expenditure
amounts were $18.2 million,  $20.4 million, and $16.8 million in 2004, 2003, and
2002, respectively.  The changes from year to year reflect expansion projects by
developers  in the  Company's  service  areas.  Funds are received in advance of
incurring  costs for these  projects.  Advances  are  normally  refunded  over a
40-year  period  without  interest.  Future  payments for advances  received are
listed under contractual obligations above.

     Management expects the Company to incur non-company-funded  expenditures in
2005.  These  expenditures  will be financed by  developers  through  refundable
advances  for   construction   and   non-refundable   contributions  in  aid  of
construction.   Developers   are  required  to  deposit  the  cost  of  a  water
construction project with the Company prior to commencing  construction work, or
the developers  may construct the  facilities  themselves and deed the completed
facilities to the Company. Because  non-company-funded  construction activity is
solely at the discretion of developers,  management  cannot predict the level of
future  activity.  The cash  flow  impact  is  expected  to be minor  due to the
structure of the arrangements.

     Capital  Structure.  In 2004,  common  stockholders  equity increased $43.1
million,  or 18%,  primarily due to the issuance of common stock in August 2004.
The long-term  debt portion of the capital  structure  increased in 2004 by $2.6
million,  primarily  due to  additional  debt issued for New Mexico  Water.  See
Long-Term Financing section above for additional information.

     Total  capitalization  at December  31, 2004 was $565.9  million and $520.2
million at December  31,  2003.  The Company  expects  that its plan for using a
balanced approach of common stock and long-term debt for financing, coupled with
increased  earnings above dividend  growth,  will increase the equity portion of
capitalization in future years. At December 31, capitalization ratios were:

                                          2004             2003
                                          ----             ----
Common equity                             50.8%            47.0%
Preferred stock                            0.6%             0.7%
Long-term debt                            48.6%            52.3%

     The return (from both  regulated and  non-regulated  operations) on average
common equity was 9.8% in 2004 compared to 9.1% in 2003.



     Acquisitions.  Although  there  were  no  significant  acquisitions  in the
periods presented, the following acquisitions were completed in 2004 and 2003:

     In April 2004, the Company  acquired the stock of National  Utility Company
(NUC) and land from owners of NUC for $0.9 million in cash. The Company  retired
NUCs stock and merged it into New Mexico Water Service Company.  Revenue for NUC
for the 8-month  period in 2004 was $0.4 million and net income was  break-even.
The  purchase  price was  approximately  equal to rate base,  and an  immaterial
amount of goodwill was recorded for the transaction.

     In April 2003, the Company  acquired the Kaanapali  Water  Corporation  for
$6.1  million  in  cash  after  certain   adjustments.   After   completing  the
acquisition,  the entitys name was changed to Hawaii Water Service Company, Inc.
Hawaii Water provides water utility  services to 520 customers in Maui,  Hawaii.
The final purchase  price is expected to be lowered by $0.1 million,  which will
be  collected  from the seller after  certain  matters are  resolved.  For 2004,
revenue was $3.3 million and net income was $0.2 million.

     Real Estate Program. The Company owns a certain amount of real estate. From
time to time,  certain  parcels are deemed  unnecessary  or no longer  useful in
water  utility  operations.  Most surplus  properties  have a low cost basis.  A
program was developed to realize the value of certain surplus properties through
sale or lease of those  properties.  The program will be ongoing for a period of
several years. Property sales produced no pretax gains in 2004, and $4.6 million
and $3.0 million in 2003 and 2002, respectively.  As sales are dependent on real
estate market  conditions,  future sales may or may not be at prior year levels.
Due to the issues  reported in the RATES and REGULATIONS  section,  future sales
may be  impacted  if the CPUC rules  against  the  Company's  position  on these
transactions.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     The Company maintains its accounting  records in accordance with accounting
principles generally accepted in the United States of America and as directed by
the regulatory  commissions to which its operations are subject.  The process of
preparing  financial  statements  requires  the use of  estimates on the part of
management.  The estimates used by management are based on historical experience
and  an  understanding  of  current  facts  and  circumstances.   A  summary  of
significant  accounting  policies  are listed in Footnote 2 of the  Consolidated
Financial Statements,  and other footnotes provide additional  information.  The
following  sections  describe  the  level  of  subjec-  tivity,   judgment,  and
variability  of  estimates  that could have a material  impact on the  financial
condition, operating performance, and cash flows of the business.

     Regulated Utility Accounting. Because the Company operates extensively in a
regulated  business,  it is subject to the  provisions of Statement of Financial
Accounting  Standards (SFAS) No. 71, Accounting for the Effects of Certain Types
of  Regulation.  Application  of SFAS No. 71  requires  accounting  for  certain
transactions in accordance with regulations defined by the respective regulatory
commission  of  that  state.  In the  event  that  a  portion  of the  Company's
operations  were no longer subject to the provisions of SFAS No. 71, the Company
would be required to write off related  regulatory  assets and liabilities  that
are not  specifically  recoverable  and  determine  if  other  assets  might  be
impaired.  If a regulatory commission determined that a portion of the Company's
assets were not recoverable in customer rates,  the Company would be required to
determine if it had suffered an asset impairment that would require a write-down
in the assets valuation.  There had been no such asset impairment as of December
31, 2004.  Additional  information relating to regulatory assets and liabilities
are listed in Footnote 2 of the Consolidated Financial Statements.



     Revenue  Recognition.  Revenue is estimated for metered customers for water
used  between  the  last  reading  of the  customers  meter  and  the end of the
accounting period. This estimate is based on the usage from the last bill to the
customer,  which normally covers a 30-day period,  and is prorated from the last
meter read date to the end of the accounting  period.  The amount of variability
is low at December 31, as this is one of the lowest usage months of the year and
usage for the previous 30-day period is relatively  consistent  during this time
of the year. Actual usage may vary from this estimate.

     Flat-rate  customers  are billed in advance at the beginning of the service
period.  Since  these  are  constant  amounts,  appropriate  adjustments  can be
calculated to determine the revenue related to the applicable period.

     Estimated Expenses.  Some expenses are recorded using estimates,  as actual
payments are not known or processed by the  accounting  deadline.  Estimates are
made for unbilled  purchased  water,  unbilled  purchased  power,  unbilled pump
taxes,  payroll, and other types of similar expenses.  While management believes
its estimates are  reasonable,  actual results could vary.  Differences  between
actual results and estimates are recorded in the period when the  information is
known.

     Expense-Balancing and Memorandum Accounts.  Expense-balancing  accounts and
memorandum accounts (offsetable  expenses) represent  recoverable costs incurred
but not billed to customers.  The amounts  included in these accounts  relate to
rate changes charged to the Company for purchased  water,  purchased  power, and
pump taxes that are different from amounts  incorporated into the rates approved
by the  CPUC.  The  Company  does not  record  expense-balancing  or  memorandum
accounts in its financial statements as revenue, nor as a receivable,  until the
CPUC and other  regulators  have  authorized  recovery  of the higher  costs and
customers  have been billed.  Therefore,  a timing  difference may occur between
when costs are  recognized  and the  recognition  of  associated  revenues.  The
balancing  and  memorandum  accounts are only used to track the  specific  costs
outside of the  financial  statements.  The cost  changes,  which are beyond the
Company's control,  are referred to as offsetable expenses because under certain
circumstances,  they are  recoverable  from  customers  in  future  offset  rate
increases.  During 2003 and 2004, the CPUC gave approval to charge customers for
a portion of the offsetable expenses (see Rates and Regulations).  Additionally,
the Company may file with the CPUC for its offsetable expenses incurred in 2004.
The amounts requested may not be ultimately  collected through rates, as amounts
may be  disallowed  during the review  process or subject to an  earnings  test.
While  the  adjustments  would  not  impact  previously  recorded  amounts,  the
adjustments  may change  future  earnings  and cash  flows.  The Company has not
compiled its offsetable  expenses  related to 2004 and therefore  cannot provide
estimates of what the ultimate collection will be from these accounts.

     Washington  Water, New Mexico Water, and Hawaii Water did not have material
amounts in expense-balancing or memorandum accounts.

     Income Taxes. Significant judgment is required in determining the provision
for income  taxes.  The process  involves  estimating  current tax  exposure and
assessing temporary  differences resulting from treatment of certain items, such
as depreciation,  for tax and financial statement  reporting.  These differences
result in  deferred  tax  assets  and  liabilities,  which are  reported  in the
consolidated  balance sheet.  Management  must also assess the  likelihood  that
deferred tax assets will be recovered in future  taxable  income.  To the extent
recovery is unlikely,  a valuation  allowance would be required.  If a valuation
allowance was required,  it could significantly  increase income tax expense. In
managements  view, a valuation  allowance was not required at December 31, 2004.
Detailed  schedules  relating to income taxes are provided in Footnote 11 of the
Consolidated Financial Statements.

     Employee  Benefit  Plans.  The Company  incurs  costs  associated  with its
pension and postretirement health care benefits plans. To measure the expense of
these  benefits,  management  must estimate  compensation  increases,  mortality
rates,  future health cost  increases,  and discount rates used to value related
liabilities  and  to  determine  appropriate  funding.   Management  works  with
independent  actuaries to measure these  benefits.  Different  estimates  and/or
actual  amounts  could  result  in  significant   variances  in  the  costs  and
liabilities  recognized for these benefit plans. The estimates used are based on
historical experience,  current facts, future expectations,  and recommendations
from independent advisors and actuaries.

     The  Company  uses an  investment  advisor  to  provide  expert  advice for
managing  investments in these plans.  To diversify  investment  risk, the plans
goal is to invest 40%-60% of the assets in domestic equity mutual funds,  5%-15%
in foreign equity mutual funds, and 35%-45% in bond funds. At December 31, 2004,
50% of the assets were invested in domestic equity mutual funds,  10% in foreign
equity  mutual funds,  and 40% in bond funds.  Based on the market values of the
investment  funds for the year ended  December 31, 2004, the total return on the
pension plan assets was 13%. For 2003 and 2002,  returns were 19% and a negative
3.3%, respectively.  Future returns on investments could vary significantly from
estimates  and could  impact  earnings  and cash flows.  Management  expects any
changes to these costs to be recovered in future rate  filings,  mitigating  the
financial  impact.

     For  measurement in 2004,  management  estimated the discount rate at 6.0%,
which  approximates  the rate of Moodys  AA-rated  bonds at December  2004.  The
discount  rate used for 2003 was 6.25%  using the same  methodology.  Management
assumed the rate of compensation  to increase 3.0% in 2005 and 3.0%  thereafter.
Any  change in these  assumptions  would  have an effect on the  service  costs,
interest costs,  and accumulated  benefit  obligations.  Additional  information
related to employee  benefit plans is listed in Footnote 12 of the  Consolidated
Financial  Statements.

     Workers  Compensation,  General  Liability,  and Other  Claims. For workers
compensation,  the Company  utilizes an actuary firm to estimate the  discounted
liability associated with claims submitted and claims not yet submitted based on
historical  data.  These estimates could vary  significantly  from actual claims
paid, which could impact earnings and cash flows.  For general  liability claims
and other claims,  management estimates the cost incurred but not yet paid using
historical  information.  Although  the Company has  insurance  policies,  it is
primarily self-insured due to the high deductibles. Actual costs could vary from
these estimates.  Management  believes actual costs incurred would be allowed in
future rates, mitigating the financial impact.

     Contingencies.  The Company did not record any  provisions  relating to the
contingencies  reported in Footnote 15 of the Consolidated Financial Statements,
as these  did not  qualify  for  recording  under  SFAS No.  5,  Accounting  for
Contingencies,  or other  accounting  standards.  If  managements  assessment is
incorrect,  these items could have a material impact on the financial condition,
results of operations, and cash flows of the business.


FINANCIAL RISK MANAGEMENT

     The Company does not  participate  in hedge  arrangements,  such as forward
contracts, swap agreements, options, or other contractual agreements relative to
the  impact  of  market  fluctuations  on  the  Company's  assets,  liabilities,
production, or contractual commitments.  The Company operates only in the United
States and, therefore, is not subject to foreign currency exchange rate risks.

     Terrorism Risk. Due to terrorist risks, the Company has heightened security
at its  facilities  over the past few years and has taken added  precautions  to
protect its  employees  and the water  delivered to  customers.  The Company has
complied  with  the  United  States   Environmental   Protection   Agency  (EPA)
regulations concerning vulnerability assessments and has made filings to the EPA
as required. In addition, communication plans have been developed as a component
of the  Company's  procedures  related to this risk.  While the Company does not
make public comments on its security  programs,  the Company has been in contact
with  federal,  state,  and local law  enforcement  agencies to  coordinate  and
improve water delivery systems security.

     Interest Rate Risk. The Company is subject to interest rate risk,  although
this risk is lessened because the Company operates in a regulated  industry.  If
interest  costs were to  increase,  management  believes  rates  would  increase
accordingly. The majority of debt is long-term,  fixed-rate.  Interest rate risk
does exist on short-term  borrowings within the Company's credit facilities,  as
these  interest  rates are variable.  The Company also has interest rate risk on
new financing,  as higher  interest cost may occur on new debt if interest rates
increase.

     Stock Price Risk.  Because the Company  operates  primarily  in a regulated
industry,  its  stock  price  risk  is  somewhat  lessened;  however,  regulated
parameters  also can be recognized as limitations to operations,  earnings,  and
the ability to respond to certain business condition changes. Prior to 2004, the
Company experienced stock price risk because of the impact on earnings caused by
the delay of certain CPUC decisions.  An adverse change in the stock price could
make use of common stock more expensive in the future.

     Stock Market  Performance Risk. The Company's stock price could be impacted
by changes in the general stock market. This could impact the costs of obtaining
funds through the equity markets. Stock market performance could also impact the
Company  through the  investments  by the  Company's  defined  benefit  plan and
postretirement  medical  benefit plan.  The Company is  responsible  for funding
these plans.  Plan  investments  are made in stock market  equities using mutual
funds and in corporate  bonds.  Poor  performance of the equity and bond markets
could result in increased costs and additional funding requirements due to lower
investment  returns.  Management  believes the Company  would be able to recover
these higher costs in customer rates.

     Equity Risk. The Company does not have equity  investments and,  therefore,
does not have equity risks.

RECENT ACCOUNTING PRONOUNCEMENTS AND LAW CHANGES

     The description  and impact of recent  accounting  pronouncements  that are
effective  for  the  periods  reported  are  described  in  Footnote  2  of  the
Consolidated Financial Statements.

     As of the filing date,  there were no accounting  pronouncements  affecting
future  periods  that are  expected to have a material  impact on the  Company's
financial condition, results of operations, or cash flows.

Amounts in thousands, except per share data and share data


1
ORGANIZATION AND OPERATIONS

     California  Water  Service Group  (Company),  a holding  company  operating
through its wholly owned subsidiaries,  provides water utility and other related
services in California,  Washington,  New Mexico,  and Hawaii.  California Water
Service  Company (Cal  Water),  Washington  Water  Service  Company  (Washington
Water),New  Mexico Water Service  Company (New Mexico  Water),  and Hawaii Water
Service Company,  Inc. (Hawaii Water) provide  regulated  utility services under
the rules and  regulations of their  respective  states  regulatory  commissions
(jointly  referred  to  as  the  Commissions).  CWS  Utility  Services  provides
non-regulated water utility and utility-related  services.  The Company operates
primarily in one business segment, providing water and related utility services.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles  of  Consolidation  and  Accounting   Records.The   consolidated
financial  statements  include the  accounts of the Company and its wholly owned
subsidiaries.  Inter-company transactions and balances have been eliminated. The
accounting  records of the Company are maintained in accordance with the uniform
system of accounts prescribed by the Commissions.

     Reclassifications.  Certain  prior years  amounts  have been  reclassified,
where necessary, to conform to the current year presentation. Use of

     Estimates.   The  preparation  of  consolidated   financial  statements  in
conformity with accounting principles generally accepted in the United States of
America  requires  management to make estimates and assumptions  that affect the
reported  amounts of assets and liabilities and disclosure of contingent  assets
and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses  during the  reporting  period.  Actual  results  could
differ from those estimates.

     Revenue.  Revenue consists of monthly cycle customer billings for regulated
water  and  wastewater  services  at rates  authorized  by the  Commissions  and
billings to certain  non-regulated  customers.  Revenue  from  metered  accounts
includes  unbilled  amounts based on the  estimated  usage from the latest meter
reading  to the end of the  accounting  period.  Flat-rate  accounts,  which are
billed at the beginning of the service period,  are included in revenue on a pro
rata basis for the portion applicable to the current accounting period.

     The Company  provides an allowance  for doubtful  accounts.  The balance of
customer  receivables is net of the allowance for doubtful  accounts at December
31, 2004 and 2003 of $287 and $289,  respectively.  The  activity in the reserve
account is as follows:


                                                    2004               2003
Beginning  balance                                 $  289             $ 181
Provision for uncollectible accounts                1,073               833
Net write-off of uncollectible accounts            (1,075)             (725)
                                                   ------             ------
Ending balance                                     $  287             $ 289
                                                   ------             ------



     Non-Regulated    Revenue.Revenues   from   non-regulated   operations   and
maintenance  agreements  are  recognized  when  services  have been  rendered to
companies or municipalities  under such agreements.  Expenses are netted against
the  revenue  billed  and are  reported  in Other  income  and  expenses  on the
Consolidated  Statements of Income.  Other  non-regulated  revenue is recognized
when title has  transferred to the buyer, or ratably over the term of the lease.
For  construction and design  services,  revenue is generally  recognized on the
completed  contract  method,  as most  projects are completed in less than three
months.  One construction and design project spanned multiple years, and revenue
was recognized using the percentage-of-completion  method based on a zero profit
margin  until  project  completion  in 2002.  See  Footnote 3, Other  Income and
Expenses.

     Expense-Balancing and Memorandum Accounts. Expense-balancing and memorandum
accounts are used to track suppliers rate changes for purchased water, purchased
power,  and pump taxes that are not included in customer  water rates.  The cost
changes  are  referred  to  as  offsetable   expenses,   because  under  certain
circumstances, they are recoverable from customers (or refunded to customers) in
future rates designed to offset the cost changes from the suppliers. The Company
does not record the balancing and  memorandum  accounts until the Commission has
authorized a change in customer rates and the customer has been billed.

     Utility  Plant.  Utility  plant is  carried  at  original  cost when  first
constructed or purchased, except for certain minor units of property recorded at
estimated  fair values at the date of  acquisition.  When  depreciable  plant is
retired,  the cost is eliminated  from utility plant accounts and such costs are
charged  against  accumulated  depreciation.  Maintenance  of  utility  plant is
charged to operating expenses as incurred.  Maintenance projects are not accrued
for in  advance.  Interest  is  capitalized  on plant  expenditures  during  the
construction  period and amounted to $824 in 2004, $1,995 in 2003, and $1,473 in
2002.

     Intangible assets acquired as part of water systems purchased are stated at
amounts  as  prescribed  by the  Commissions.  All other  intangibles  have been
recorded  at cost  and are  amortized  over  their  useful  lives.  Included  in
intangible  assets is $6,515 paid to the City of  Hawthorne in 1996 to lease the
citys water system and associated water rights.  The asset is being amortized on
a straight-line basis over the 15-year life of the lease.

     The  following  table  represents  depreciable  plant and  equipment  as of
December 31:

                                                        2004            2003
Equipment                                          $  214,202       $  199,157
Transmission and distribution plant                   819,793          772,641
Office buildings and other structures                  68,937           66,260
                                                   ----------       ----------
        Total                                      $1,102,932       $1,038,058
                                                   ----------       ----------

     Depreciation of utility plant for financial  statement purposes is computed
on a straight-line basis over the assets estimated useful lives as follows:

                                                        Useful Lives
Equipment                                                5-50 years
Transmission and distribution plant                     40-65 years
Office buildings and other structures                      50 years

     The provision for  depreciation  expressed as a percentage of the aggregate
depreciable asset balances was 2.6% in 2004, 2.5% in 2003, and 2.4% in 2002. For
income tax purposes, as applicable,  the Company computes depreciation using the
accelerated  methods  allowed  by  the  respective  taxing  authorities.   Plant
additions  since  June 1996 are  depreciated  on a  straight-line  basis for tax
purposes in accordance with tax regulations.



     Cash Equivalents.  Cash equivalents  include highly liquid investments with
maturities  of  three  months  or  less.  As of  December  31,  2004  and  2003,
investments  in  money  market  funds  were  $6,133  and $0,  respectively,  and
investments in high-quality commercial paper were $4,997 and $0, respectively.

     Restricted Cash.  Restricted cash primarily  represents  proceeds collected
through a  surcharge  on certain  customers  bills plus  interest  earned on the
proceeds and is used to service California Safe Drinking Water Bond obligations.
In addition, there are compensating balances at a bank in support of borrowings.
All  restricted  cash is classified in other prepaid  expenses.  At December 31,
2004  and  2003,  the  amounts  of  restricted  cash  were  $1,337  and  $1,154,
respectively.

     Regulatory  Assets and Liabilities.  The Company records  regulatory assets
for future  revenues  expected to be realized in  customers  rates when  certain
items are  recognized  as  expenses  for  rate-making  purposes.  The income tax
temporary differences relate primarily to the difference between book and income
tax  depreciation  on  utility  plant  that was  placed in  service  before  the
regulatory   Commissions   adopted   normalization  for  rate-making   purposes.
Previously,  the tax effect was passed onto customers.  In the future, when such
timing  differences  reverse,  the Company will be able to include the impact in
customer rates. The regulatory assets associated with income tax differences are
net of  deferred  income  taxes that were  provided  at current  tax rates.  The
differences will reverse over the remaining book lives of the related assets.

     In  addition,  regulatory  assets  include  items  that are  recognized  as
liabilities for financial statement purposes,  which will be recovered in future
customer rates. The liabilities  relate to  postretirement  benefits,  vacation,
self-insured workers compensation, and asset retirement obligations.

     Regulatory  liabilities  represent  future  benefits to ratepayers  for tax
deductions that will be allowed in the future for funds received as Advances for
Construction and  Contributions in Aid of Construction.  Regulatory  liabilities
also reflect  timing  differences  provided at higher than the current tax rate,
and which will flow through to future ratepayers.

     Regulatory  assets and  liabilities  are  comprised of the  following as of
December 31:

                                                        2004            2003

impairment  annually,  or when events or changes in business  circumstances have
occurred  that  indicate  the  carrying  amount of such  assets may not be fully
realizable.  Potential  impairment  of  assets  held  for use is  determined  by
comparing the carrying amount of an asset to the future  undiscounted cash flows
expected to be generated by that asset. If assets are considered to be impaired,
the  impairment to be recognized is measured by the amount by which the carrying
value of the assets  exceeds  the fair value of the  assets.  There have been no
such impairments as of December 31, 2004 and 2003.



     Long-Term  Debt  Premium,  Discount and Expense.  The discount and issuance
expense on long-term  debt is amortized  over the original  lives of the related
debt issues.  Premiums  paid on the early  redemption of certain debt issues and
unamortized  original  issue  discount and expense of such issues are  amortized
over the life of new debt issued in conjunction with the early redemption. These
amounts  were $0,  $3,154,  and $2,449 in 2004,  2003,  and 2002,  respectively.
Amortization  expense  included in interest expense was $660, $415, and $183 for
2004, 2003, and 2002, respectively.

     Accumulated  Other   Comprehensive   Loss.  The  Company  has  an  unfunded
Supplemental   Executive  Retirement  Plan.  The  unfunded  accumulated  benefit
obligation of the plan, less the accrued benefit, exceeds the unrecognized prior
service cost resulting in an accumulated other  comprehensive loss that has been
recorded net of tax as a separate component of Stockholders Equity.

     Advances for  Construction.  Advances for Construction  consist of payments
received from developers for  installation of water  production and distribution
facilities to serve new  developments.  Advances are excluded from rate base for
rate-setting  purposes.  Annual refunds are made to developers  without interest
over a 20-year or 40-year period. Refund amounts under the 20-year contracts are
based on annual revenues from the extensions.  Unrefunded balances at the end of
the contract period are credited to  Contributions  in Aid of Construction  when
they   are  no   longer   refundable   in   accordance   with   the   contracts.
Reclassifications  were $0 in 2004 and  $1,813  in 2003.  Refunds  on  contracts
entered  into  since 1982 are made in equal  annual  amounts  over 40 years.  At
December 31, 2004 and 2003, the amounts  refundable under the 20-year  contracts
were $828 and $1,350,  respectively,  and under 40-year  contracts were $129,730
and  $119,699,  respectively.  In  addition,  other  Advances  for  Construction
totaling  $734  and  $903 at  December  31,  2004 and  2003,  respectively,  are
refundable based upon customer  connections.  Estimated  refunds of advances for
each succeeding year (2005 through 2009) are $5,036, $4,556, $4,403, $4,364, and
$4,344, and $108,589 thereafter.

     Contributions in Aid of Construction.  Contributions in Aid of Construction
represent  payments  received from  developers,  primarily  for fire  protection
purposes,  which are not subject to refunds.  Facilities funded by contributions
are included in utility plant, but excluded from rate base. Depreciation related
to assets  acquired from  contributions  is charged to  Contributions  in Aid of
Construction.

     Income  Taxes.  The Company  accounts  for income taxes using the asset and
liability  method.  Deferred tax assets and  liabilities  are recognized for the
future tax  consequences  attributable  to  differences  between  the  financial
statement  carrying  amounts  of  existing  assets  and  liabilities  and  their
respective tax bases.  Measurement of the deferred tax assets and liabilities is
at enacted tax rates  expected to apply to taxable  income in the years in which
those temporary  differences are expected to be recovered or settled. The effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
the period that includes the enactment date.

     The Company  anticipates  that future rate action by the  Commissions  will
reflect  revenue  requirements  for the tax  effects  of  temporary  differences
recognized,  which  have  previously  been  flowed  through  to  customers.  The
Commissions have granted the Company rate increases to reflect the normalization
of the tax benefits of the federal accelerated methods and available  Investment
Tax Credits (ITC) for all assets placed in service after 1980.  ITC are deferred
and amortized over the lives of the related properties for book purposes.

     Advances for Construction and Contributions in Aid of Construction received
from developers subsequent to 1986 were taxable for federal income tax purposes,
and those received  subsequent to 1991 were subject to California income tax. In
1996, the federal tax law, and in 1997, the California tax law, changed and only
deposits for new services were taxable.  In late 2000, federal  regulations were
further modified to exclude fire services from tax.



     Worker's  Compensation,  General  Liability and Other  Claims.  For workers
compensation,  the Company  utilized an actuary firm to estimate the  discounted
liability associated with claims submitted and claims not yet submitted based on
historical  data.  For general  liability  claims and other claims,  the Company
estimates the cost incurred but not yet paid using historical information.

     Earnings  Per  Share.  Basic  earnings  per share  (EPS) is  calculated  by
dividing  income  available to common  stockholders  (net income less  preferred
stock dividends of $153) by the weighted average shares  outstanding  during the
year.  Diluted  EPS  is  calculated  by  dividing  income  available  to  common
stockholders by the weighted average shares outstanding,  including  potentially
dilutive  shares as determined by application of the treasury stock method.  The
difference  between basic and diluted  weighted  average  number of common stock
outstanding is the effect of dilutive common stock options outstanding.

     Stock-Based Compensation.  The Company has a stockholder-approved Long-Term
Incentive Plan that allows granting of non-qualified stock options.  The Company
has adopted the  disclosure  requirements  of Statement of Financial  Accounting
Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation,  "as amended
by SFAS No.148, "Accounting for Stock-Based Compensation - Transition Disclosure
- - An Amendment to SFAS No.  123," and as  permitted  by the  statement,  applies
Accounting  Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to
Employees,"  for its plan.  All of the  Company's  outstanding  options  have an
exercise  price  equal to the  market  price on the date they were  granted.  No
compensation  expense was recorded for the years ended December 31, 2004,  2003,
or 2002.

     The table below illustrates the effect on net income and earnings per share
as if the Company had applied the fair value recognition  provisions of SFAS No.
123,   "Accounting  for  Stock-Based   Compensation,"  to  stock-based  employee
compensation.

     Recent   Accounting   Pronouncements.   In  December  2003,  the  Financial
Accounting Standards Board (FASB) issued Interpretation No. 46R,  "Consolidation
of  Variable   Interest   Entities,"  which  amended   Interpretation   No.  46,
"Consolidation  of Variable  Interest  Entities." The revision  exempted certain
entities and modified the effective dates of Interpretation No. 46. The original
guidance issued under Interpretation No. 46 in January 2003 is still applicable.
Interpretation   No.  46  and   Interpretation  No.  46R  provide  guidance  for
determining when a primary  beneficiary  should  consolidate a variable interest
entity or equivalent  structure  that functions to support the activities of the
primary  beneficiary.  Interpretation  No. 46R was effective March 31, 2004. The
adoption  of  Interpretation  No.  46R did not impact  the  Company's  financial
position, results of operations, or cash flows.

     In  December  2003,  the FASB issued  Statements  of  Financial  Accounting
Standards (SFAS) No. 132 (revised),  "Employers'  Disclosures about Pensions and
Other Postretirement  Benefits - An Amendment of FASB Statements No. 87, 88, and
106," which changed  certain  disclosures.  SFAS No. 132 (revised) was effective
for  fiscal  years  ending  after  December  15,  2003,  and was  effective  for
interim-period  disclosures  beginning  after December 15, 2003. As the revision
relates to disclosure  requirements,  the adoption of SFAS No. 132 (revised) did
not impact the Company's  financial  position,  results of  operations,  or cash
flows.

     In May  2004,  the  FASB  issued  FASB  Staff  Position  (FSP)  No.  106-2,
"Accounting  and Disclosure  Requirements  Related to the Medicare  Prescription
Drug,  Improvement,  and Modernization Act of 2003." FSP No. 106-2 was effective
for the first quarter after June 15, 2004,  and replaces FSP No. 106-1.  FSP No.
106-1 was effective for the Company's  consolidated financial statements for the
year ended December 31, 2003. The Company has determined its retiree health plan
is actuarially equivalent and would qualify for the subsidy. Because the Company
is  regulated,  FSP No. 106-2 did not have an impact to the income  statement or
cash flows in 2004.  The adjustment for FSP No. 106-2 impacted the balance sheet
only, decreasing liabilities and regulatory assets by $663. The Company believes
it will be eligible for the subsidy  starting in 2006. The Company has estimated
the impact of the subsidy on premiums  charged to  retirees,  but has not made a
final decision at this time;  therefore,  adjustments  may occur once a decision
has been made.

     In November  2004,  the FASB issued  SFAS No.  151,  "Inventory  Costs - an
Amendment to ARB No. 43, Chapter 4." The statement  clarifies the accounting for
abnormal amounts of idle facility expense,  freight,  handling costs, and wasted
material.  The statement is effective for fiscal years  beginning after June 15,
2005.  The adoption of this  statement  is not expected to impact the  Company's
financial position, results of operations, or cash flows.

     In December  2004,  the FASB issued SFAS No. 153,  "Exchange of Nonmonetary
Assets." The  statement  amends  Opinion No. 29 to eliminate  the  exception for
non-monetary  exchanges  of similar  productive  assets and  replaces  it with a
general  exception  for  exchanges  of  non-monetary  assets  that  do not  have
commercial  substance.  The  statement is effective  for fiscal years  beginning
after June 15, 2005.  The  adoption of this  statement is not expected to impact
the Company's financial position, results of operations, or cash flows.

     In December 2004, the FASB issued SFAS No. 123 (revised 2004),  Share-Based
Payment,  which revises SFAS No. 123,  Accounting for Stock-Based  Compensation.
The statement  requires a public entity to measure the cost of employee services
received in exchange for an award of equity  instruments based on the grant-date
fair value of the award (with  limited  exceptions).  The statement is effective
for the Company in the first interim period that begins after June 15, 2005. The
adoption of this  statement is not expected to  materially  impact the Company's
financial position,  results of operations, or cash flows for equity instruments
previously granted. The Company intends to request stockholder approval of a new
long-term   incentive  plan  in  2005,   which  includes   issuances  of  equity
instruments.  At this time, the Company  cannot  estimate the impact of this new
long-term  incentive  plan  on the  Company's  financial  position,  results  of
operations, or cash flows.

     In December  2004,  the FASB  issued FSP No.  109-1,  "Application  of FASB
Statement No. 109,  Accounting for Income Tax, to the Tax Deduction on Qualified
Production  Activities Provided by the American Jobs Creations Act of 2004." FSP
No. 109-1 gives  guidance on the  application  of SFAS No. 109 to the provisions
within the  American  Jobs  Creation  Act of 2004 that allow a tax  deduction on
qualified production  activities.  The guidance states that the deduction should
be accounted  for as a special  deduction in  accordance  with SFAS No. 109. The
adoption of this  guidance is not expected to  materially  impact the  Company's
financial position, results of operations, or cash flows.

     Operating and maintenance  services and meter reading and billing  services
are provided for water and  wastewater  systems  owned by private  companies and
municipalities.  The agreements call for a fee-per-service or a flat-rate amount
per month due from companies and  municipalities.  Leases have been entered into
with  telecommunications  companies for cellular  phone  antennas  placed on the
Company's  property.  Water rights brokering activity involves  purchasing water
rights from third  parties and  reselling  those rights to other third  parties.
Design and construction  services are the design and installation of water mains
and other  water  infrastructure  for others  outside  the  Company's  regulated
service areas.

ACQUISITIONS

     In 2004, after receiving  regulatory  approval,  the Company's wholly owned
subsidiary,  New Mexico Water,  acquired the stock of National  Utility Company.
The purchase was for $900 in cash for the approximate amount of rate base of the
water system and for certain real estate used by the water system.

     In 2003,  after receiving  regulatory  approval,  the Company  acquired the
Kaanapali Water  Corporation  and renamed the  corporation  Hawaii Water Service
Company,  Inc. The purchase was for $6,094 in cash for the approximate amount of
rate  base.  If the rate base is  adjusted  by the  Commission  in the next rate
proceeding, the purchase price will be adjusted accordingly.



     During 2002, after receiving regulatory approval,  the Company acquired the
assets of Rio Grande Utility  Corporation  (Rio Grande) through its wholly owned
subsidiary,  New Mexico Water.  The purchase  includes the water and  wastewater
assets  of  Rio  Grande,   which  serves  water  and  wastewater   customers  in
unincorporated  areas of Valencia  County,  New Mexico.  The purchase  price was
$2,300 in cash, plus assumption of $3,100 in outstanding debt. Rate base for the
system is $5,400, including intangible water rights valued at $732.

     Condensed  balance  sheets and pro forma  results of  operations  for these
acquisitions  have not been presented because the effects of these purchases are
not material.  Acquisitions  that involved purchase of assets were accounted for
under the purchase method of accounting. Minimal or no goodwill was recorded for
these acquisitions.

PREFERRED STOCK

     As of December 31, 2004 and 2003,  380,000  shares of preferred  stock were
authorized.  Dividends on  outstanding  shares are payable  quarterly at a fixed
rate before any dividends can be paid on common stock.

     The outstanding  139,000 shares of $25 par value cumulative,  4.4% Series C
preferred shares are not convertible to common stock. A premium of $243 would be
due to preferred  stock  shareholders  upon  voluntary  liquidation of Series C.
There is no premium in the event of an  involuntary  liquidation.  Each Series C
preferred share is entitled to 16 votes,  with the right to cumulative  votes at
any election of directors.

     The  Company is  authorized  to issue 25 million  shares of $0.01 par value
common stock. As of December 31, 2004 and 2003, 18,367,246 shares and 16,932,046
shares, respectively, of common stock were issued and outstanding.

     Dividend Reinvestment and Stock Purchase Plan. The Company's transfer agent
has a Dividend  Reinvestment  and Stock  Purchase  Plan (Plan).  Under the Plan,
stockholders may reinvest dividends to purchase  additional Company common stock
without  commission  fees. The Plan also allows existing  stockholders and other
interested investors to purchase Company common stock through the transfer agent
up to  certain  limits.  The  Company's  transfer  agent  operates  the Plan and
purchases shares on the open market to provide shares for the Plan.

     Stockholder  Rights Plan. The Company's  Stockholder  Rights Plan (Plan) is
designed to provide stockholders protection and to maximize stockholder value by
encouraging a  prospective  acquirer to negotiate  with the Board.  The Plan was
adopted in 1998 and authorized a dividend  distribution  of one right (Right) to
purchase 1/100th share of Series D Preferred Stock for each outstanding share of
Common Stock in certain circumstances.  The Rights are for a 10-year period that
expires in February 2008.

     Each  Right  represents  a right to  purchase  1/100th  share  of  Series D
Preferred Stock at the price of $120,  subject to adjustment  (Purchase  Price).
Each share of Series D Preferred  Stock is entitled to receive a dividend  equal
to 100 times any  dividend  paid on common  stock and 100 votes per share in any
stockholder  election.  The  Rights  become  exercisable  upon  occurrence  of a
Distribution   Date.  A  Distribution  Date  event  occurs  if  (a)  any  person
accumulates 15% of the then outstanding  Common Stock, (b) any person presents a
tender offer which would cause the persons ownership level to exceed 15% and the
Board determines the tender offer not to be fair to the Company's  stockholders,
or (c) the Board determines that a stockholder maintaining a 10% interest in the
Common  Stock could have an adverse  impact on the  Company or could  attempt to
pressure the Company to repurchase the holders shares at a premium.



     Until the  occurrence of a  Distribution  Date,  each Right trades with the
Common  Stock  and is not  separately  transferable.  When a  Distribution  Date
occurs: (a) the Company would distribute  separate Rights Certificates to Common
Stockholders  and the Rights would  subsequently  trade separate from the Common
Stock;  and (b) each holder of a Right,  other than the acquiring  person (whose
Rights would thereafter be void),  would have the right to receive upon exercise
at its then current  Purchase Price that number of shares of Common Stock having
a market  value of two times the  Purchase  Price of the Right.  If the  Company
merges into the acquiring  person or enters into any  transaction  that unfairly
favors the acquiring person or disfavors the Company's other  stockholders,  the
Right becomes a right to purchase Common Stock of the acquiring  person having a
market value of two times the Purchase Price.

     The Board may determine that in certain circumstances a proposal that would
cause  a  Distribution  Date  is in  the  Company  stockholders  best  interest.
Therefore, the Board may, at its option, redeem the Rights at a redemption price
of $0.001 per Right.

SHORT-TERM BORROWINGS

     At  December  31,  2004,  the  Company  maintained  a bank  line of  credit
providing unsecured borrowings of up to $10 million at the prime lending rate or
lower rates as quoted by the bank. Cal Water  maintained a separate bank line of
credit for an additional  $45 million on the same terms as the Company's line of
credit.  Both  agreements  required a 30-day  out-of-debt  period  during any 24
consecutive  months.  The $10 million and $45 million  lines have a  requirement
where  the  outstanding  balance  must be  below  $5  million  and $10  million,
respectively,  for a 30-day consecutive period during any 12-month period.  Both
agreements   have  a  covenant   requiring   debt  as  a  percentage   of  total
capitalization  to be less  than  67%.  At  December  31,  2004,  there  were no
borrowings on the Company or Cal Water line.

     The following table represents borrowings under the bank lines of credit:

     The first mortgage bonds and unsecured  senior notes are obligations of Cal
Water.   All  bonds  are  held  by   institutional   investors  and  secured  by

institutional  investors  and require  interest-only  payments  until  maturity,
except  series G and H, which have an annual  sinking fund  requirement  of $1.8
million  starting in 2012.  The Department of Water  Resources  (DWR) loans were
financed  under the  California  Safe  Drinking  Water  Bond Act.  Repayment  of
principal  and interest on the DWR loans is done through a surcharge on customer
bills.  Other long-term debt includes a term loan of $3.4 million for New Mexico
Water and other equipment and system  acquisition  financing  arrangements  with
financial  institutions.  Compensating  balances of $228 as of December 31, 2004
are  required by these  institutions.  Aggregate  maturities  and  sinking  fund
requirements  for each of the  succeeding  five years  (2005  through  2009) are

     A valuation allowance was not required at December 31, 2004 and 2003. Based
on historical  taxable  income and future taxable  income  projections  over the
period in which the deferred  assets are deductible,  management  believes it is
more  likely  than  not  that the  Company  will  realize  the  benefits  of the
deductible differences.

EMPLOYEE BENEFIT PLANS

     Pension  Plan.  The  Company   provides  a  qualified,   defined   benefit,
non-contributory  pension plan for substantially all employees. The Company also
maintains an unfunded,  non-qualified,  supplemental  executive retirement plan.
The cost of plans are charged to expense and utility  plant.  The Company  makes
annual  contributions  to fund the amounts accrued for pension cost. The Company
estimates  that the annual  contribution  to the pension  plan will be $5,400 in
2005.  Plan  assets in the pension  plan as of  December  31, 2004 and 2003 (the
measurement dates for the plan) were as follows:

Asset Category                  Target                  2004            2003
Bond funds                     35%-45%                 39.4%           42.9%
Equity accounts                55%-65%                 60.6%           57.1%

     The  investment  objective of the fund is to maximize the return on assets,
commensurate  with the risk the Company  Trustees deem  appropriate  to meet the
obligations  of the Plan,  minimize the volatility of the pension  expense,  and
account for  contingencies.  The  Trustees  utilize  the  services of an outside
investment  advisor and periodically  measure fund performance  against specific
indexes in an effort to generate a rate of return for the total  portfolio  that
equals or exceeds the actuarial investment rate assumptions.

     Pension  benefit  payments are generally  done in the form of purchasing an
annuity from a life insurance  company.  Benefit payments under the supplemental
executive  retirement plan are paid currently.  Benefits  expected to be paid in
each year from 2005 to 2009 are  $3,207,  $3,509,  $4,879,  $6,494,  and $7,148,
respectively.  The aggregate  benefit expected to be paid in the five years from
2010 to 2014 is $45,837.  The expected  benefit payments are based upon the same
assumption used to measure the Company's benefit obligation at December 31, 2004
and include estimated future employee service.

     The  accumulated  benefit  obligations  of the pension plan are $65,938 and
$62,368  as of  December  31,  2004 and 2003,  respectively.  The fair  value of
pension  plan assets was  $75,064 and $63,216 as of December  31, 2004 and 2003,
respectively.  The unfunded  supplemental  executive retirement plan accumulated
benefit  obligations  were $7,234 and $6,480 as of  December  31, 2004 and 2003,
respectively.

     The  data  in  the  tables  below  includes  the  unfunded,  non-qualified,
supplemental executive retirement plan.

     Savings Plan. The Company sponsors a 401(k) qualified, defined contribution
savings  plan  that  allows  participants  to  contribute  up to 20%  of  pretax
compensation. The Company matches fifty cents for each dollar contributed by the
employee  up to a maximum  Company  match of 4.0%.  Company  contributions  were
$1,443, $1,433, and $1,422, for the years 2004, 2003, and 2002, respectively.

     Other Postretirement Plans. The Company provides  substantially all active,
permanent  employees  with  medical,  dental,  and  vision  benefits  through  a
self-insured  plan.  Employees  retiring  at or after age 58,  along  with their
spouses  and  dependents,  continue  participation  in the plan by  payment of a
premium.  Plan assets are  invested in mutual  funds,  short-term  money  market
instruments,  and commercial  paper.  Retired employees are also provided with a
$5,000 life insurance benefit.

     The  Company  records  the  costs of  postretirement  benefits  during  the
employees years of active service.  The Commissions  have issued  decisions that
authorize rate recovery of tax-deductible funding of postretirement benefits and
permit  recording  of a  regulatory  asset for the portion of costs that will be
recoverable in future rates.

accrued pension  liability and the net  postretirement  benefit  liability as of
December 31, 2004 and 2003:

Weighted average assumptions as of December 31:
        Discount rate                           6.00%        6.25%      6.00%       6.25%

        Rate of compensation increases          3.00%   1.5%-4.25%        --          --


     The long-term rate of return assumption is the expected rate of return on a
balanced  portfolio  invested  roughly 60% in equities  and 40% in fixed  income
securities.  The average  return for the plan for the last five and 10 years was
6.4% and 10.1%, respectively.

     Net periodic benefit costs for the pension and other  postretirement  plans
for the years ending  December 31, 2004,  2003,  and 2002 included the following
components:

     Postretirement benefit expense recorded in 2004, 2003, and 2002 was $1,420,
$1,160, and $1,157, respectively.  The remaining net periodic benefit cost as of
December 31, 2004 of $9,019 is recoverable  through future customer rates and is
recorded as a regulatory asset. The Company intends to make annual contributions
to the plan up to the amount deductible for tax purposes.

     For 2004  measurement  purposes,  the Company assumed a 9.5% annual rate of
increase in the per capita cost of covered  benefits with the rate decreasing 1%
per year for the next five years to a  long-term  annual  rate of 4.5% per year.
The health  care cost  trend rate  assumption  has a  significant  effect on the
amounts  reported.  A  one-percentage  point change in assumed  health care cost
trends is estimated to have the following effect:

                                                1-Percentage    1-Percentage
                                                Point Increase  Point Decrease

Effect on total service and interest costs       $  552            $  (618)
Effect on accumulated postretirement
  benefit obligation                             $6,044            $(4,756)

STOCK-BASED COMPENSATION PLANS

     The Company has a stockholder-approved Long-Term Incentive Plan that allows
granting of non-qualified stock options, performance shares, and dividend units.
Under the plan, a total of 1,500,000  common  shares are  authorized  for option
grants.  Options are granted at an exercise  price that is not less than the per
share common stock market price on the date of grant.  The options vest at a 25%
rate on their  anniversary  date over their first four years and are exercisable
over a 10-year period.  At December 31, 2004, 85,500 options were exercisable at
a weighted average price of $24.82. No options were granted in 2004 or 2003.



     The fair value of stock  options  used to compute  pro forma net income and
earnings per share  disclosures  is the estimated fair value at grant date using
the Black-Scholes option-pricing model with the following assumptions:

                                                       2004    2003    2002

FAIR VALUE OF FINANCIAL INSTRUMENTS

     For those  financial  instruments for which it is practicable to estimate a
fair  value,  the  following   methods  and  assumptions  were  used.  For  cash
equivalents, accounts receivables, accounts payables, and short-term borrowings,
the carrying amount  approximates fair value because of the short-term  maturity
of the instruments.  The fair value of the Company's long-term debt is estimated
at $301 million and $289 million as of December 31, 2004 and 2003, respectively,
using a discounted  cash flow analysis,  based on the current rates available to
the Company for debt of similar maturities. The book value of the long-term debt
is $276 million and $273 million as of December 31, 2004 and 2003, respectively.
The fair value of  advances  for  construction  contracts  is  estimated  at $51
million as of December 31, 2004 and $48 million as of December  31, 2003,  based
on data provided by brokers who purchase and sell these contracts.

COMMITMENTS AND CONTINGENCIES

     Commitments.  The Company leases office facilities in many of its operating
districts.  The total paid and charged to operations for such leases was $632 in
2004, $577 in 2003, and $700 in 2002.

     The Company has long-term contracts with two wholesale water suppliers that
require the Company to purchase minimum annual water  quantities.  Purchases are
priced at the suppliers then current  wholesale water rate. The Company operates
to purchase  sufficient  water to equal or exceed the minimum  quantities  under
both contracts. The total paid under the contracts was $7,918 in 2004, $8,557 in
2003, and $6,816 in 2002.

     The Company leases the City of Hawthorne water system, which in addition to
the upfront lease payment, includes an annual payment. The 15-year lease expires
in 2011. The annual payments in 2004,  2003, and 2002 were $116, $111, and $100,
respectively. In July 2003, the Company entered into a 15-year lease of the City
of Commerce water system. The lease includes an annual lease payment of $845 per
year plus a cost savings sharing arrangement.

     Lease  payments  and  payments  called  for  in  the  above  contracts  are
summarized below.

     The water supply contract with Stockton East Water District (SEWD) requires
a fixed,  annual  payment and does not vary during the year with the quantity of
water  delivered by the district.  Because of the fixed-price  arrangement,  the
Company  operates  to receive as much  water as  possible  from SEWD in order to
minimize  the cost of  operating  Company-owned  wells used to  supplement  SEWD
deliveries.  The total paid  under the  contract  was $4,392 in 2004,  $3,779 in
2003, and $2,967 in 2002. Pricing under the contract varies annually.

     Contingencies.  In 1995,  the  State  of  Californias  Department  of Toxic
Substances  Control (DTSC) named Cal Water as a potential  responsible party for
cleanup of a toxic  contamination  plume in the Chico ground-  water.  The toxic
spill  occurred when cleaning  solvents,  which were  discharged  into the citys
sewer system by local dry cleaners,  leaked into the  underground  water supply.
The DTSC  contends  that Cal Waters  responsibility  stems from its operation of
wells in the surrounding vicinity that caused the contamination plume to spread.
While Cal Water is  cooperating  with the cleanup  effort,  Cal Water denies any
responsibility  for the  contamination  or the resulting  cleanup and intends to
vigorously  resist any action that may be brought against Cal Water. In December
2002,  Cal Water was named along with other  defendants in two lawsuits filed by
DTSC for the  cleanup of the plume.  The suits  assert that the  defendants  are
jointly  and  severally  liable for the  estimated  cleanup of $8.7  million.  A
mediation  process  has begun and no  settlement  demands by any party have been
made at this time.  Management  believes that insurance coverage exists for this
claim,  and if Cal Water were ultimately  held  responsible for a portion of the
cleanup  costs,  there would not be a material  adverse  effect to its financial
position or results of  operations.  Cal Waters  insurance  carrier is currently
paying the cost of legal representation in this matter.

     In  1995,   the   California   Legislature   enacted   the  Water   Utility
Infrastructure  Improvement Act of 1995  (Infrastructure Act) to encourage water
utilities  to sell  surplus  properties  and  reinvest in needed  water  utility
facilities.  In September  2003,  the CPUC issued  decision  D.03-09-021  in Cal
Waters 2001 GRC filing. In this decision,  the CPUC ordered Cal Water to file an
application  setting  up  an  Infrastructure  Act  memorandum  account  with  an
up-to-date accounting of all real property that was at any time in rate base and
that Cal Water had sold  since the  effective  date of the  Infrastructure  Act.
Additionally,  the decision directed the CPUC staff to file a detailed report on
its  review of Cal  Waters  application.  On  January  11,  2005,  the Office of
Ratepayer  Advocates  (ORA), a division of the CPUC responsible for representing
ratepayers, issued a report expressing its opinion that Cal Water had not proven
that  surplus  properties  sold since 1996 were no longer used and  useful.  ORA
recommended  that Cal Water be fined  $160 and that gains  from  property  sales
should generally benefit  ratepayers.  Management  strongly  disagrees with ORAs
conclusions and recommendations.



     During the period under review,  Cal Waters  cumulative  gains from surplus
property sales were $19.2 million,  which included an inter-company gain related
to a transaction with CWS Utility Services and a like-kind exchange with a third
party.  If the CPUC finds any surplus  property  sale or transfer  was  recorded
inappropriately, Cal Waters rate base could be reduced, which would lower future
revenues, net income, and cash flows.  Management believes it has fully complied
with the  Infrastructure Act and that ORAs conclusions and  recommendations  are
without   merit.   Cal  Water  intends  to  vigorously   oppose  ORAs  findings.
Accordingly,  Cal Water has not accrued a liability in the financial  statements
for ORAs recommendations.  At this time, Cal Water does not know when or how the
CPUC will rule in this matter.

     The Company is involved in other  proceedings or litigation  arising in the
ordinary course of operations.  The Company believes the ultimate  resolution of
such matters  will not  materially  affect its  financial  position,  results of
operations, or cash flows.

CONTROLS AND PROCEDURES

California Water Service Group

MANAGEMENT'S EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

     The Company  carried out an evaluation,  under the  supervision of and with
the participation of management, including the Chief Executive Officer and Chief
Financial  Officer,  of the  effectiveness  of the design and  operation  of the
Company's  disclosure  controls and procedures as of December 31, 2004, pursuant
to Rule  13a-15(e)  under the  Securities  Exchange Act of 1934.  Based on their
review of the disclosure  controls and procedures,  the Chief Executive  Officer
and  Chief  Financial  Officer  have  concluded  that the  Company's  disclosure
controls and procedures are effective in timely alerting  management to material
information that is required to be included in periodic SEC filings.

     Management,  including  the Chief  Executive  Officer  and Chief  Financial
Officer,  does not expect that the Company's  disclosure controls and procedures
or its internal  control  over  financial  reporting  will prevent or detect all
errors  and all  fraud.  A control  system,  no matter  how well  conceived  and
operated,  can  provide  only  reasonable,  not  absolute,  assurance  that  the
objectives  of the  control  system  are met.  Further,  the design of a control
system  must  reflect  the fact that  there are  resource  constraints,  and the
benefits of each control must be  considered  relative to its costs.  Because of
the inherent  limitations  in all control  systems,  no  evaluation of a control
system can provide  absolute  assurance that all control issues and instances of
fraud, if any, within the Company have been prevented or detected.

     There  was no change  in the  Company's  internal  control  over  financial
reporting  during  the  quarter  ended  December  31,  2004 that has  materially
affected,  or is reasonably likely to materially  affect, the Company's internal
control over financial reporting.


MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

     Management  is  responsible  for  establishing  and  maintaining   adequate
internal  control over  financial  reporting  (as defined in Rule  13a-15(f) and
15d-15(f)  under the  Securities  Exchange Act of 1934, as amended).  Management
assessed the  effectiveness  of the Company's  internal  control over  financial
reporting as of December 31, 2004. In making this  assessment,  management  used
the  criteria  set forth by the  Committee of  Sponsoring  Organizations  of the
Treadway Commission (COSO) in Internal Control-Integrated Framework.  Management
has concluded that, as of December 31, 2004, the Company's internal control over
financial  reporting  is  effective  based  on  these  criteria.  The  Company's
independent  registered  public accounting firm, KPMG LLP, which has audited the
financial  statements included in this Annual Report, has issued an audit report
on  managements  assessment of the  Company's  internal  control over  financial
reporting, which is included herein.



REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD OF DIRECTORS AND STOCKHOLDERS
CALIFORNIA WATER SERVICE GROUP

     We have  audited  management's  assessment,  included  in the  accompanying
Managements Report on Internal Control over Financial Reporting, that California
Water Service Group and subsidiaries  maintained effective internal control over
financial  reporting as of December 31, 2004, based on the criteria  established
in Internal  Control-Integrated  Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO).  Management of California Water
Service Group is responsible for  maintaining  effective  internal  control over
financial  reporting  and for its  assessment of the  effectiveness  of internal
control over financial reporting. Our responsibility is to express an opinion on
managements  assessment  and an opinion  on the  effectiveness  of the  internal
control  over  financial   reporting  of  California  Water  Service  Group  and
subsidiaries based on our audit.

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

     A company's internal control over financial reporting is a process designed
to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial  statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial  reporting  includes those policies and procedures that (1) pertain to
the  maintenance  of records that, in reasonable  detail,  accurately and fairly
reflect the  transactions  and  dispositions  of the assets of the company;  (2)
provide  reasonable  assurance  that  transactions  are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting  principles,  and that receipts and  expenditures  of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of  unauthorized  acquisition,  use, or  disposition  of the company's
assets that could have a material effect on the financial statements.

     Because  of its  inherent  limitations,  internal  control  over  financial
reporting  may not prevent or detect  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.

     In our opinion,  managements assessment that California Water Service Group
and subsidiaries  maintained effective internal control over financial reporting
as of December 31, 2004, is fairly stated,  in all material  respects,  based on
criteria  established  in Internal  Control-Integrated  Framework  issued by the
COSO.  Also, in our opinion,  California  Water  Service Group and  subsidiaries
maintained, in all material respects,  effective internal control over financial
reporting as of December 31, 2004, based on the criteria established in Internal
Control-Integrated Framework issued by the COSO.

     We also have  audited,  in  accordance  with the  standards  of the  Public
Company  Accounting  Oversight Board (United States),  the consolidated  balance
sheets of California  Water Service  Group and  subsidiaries  as of December 31,
2004 and  2003,  and the  related  consolidated  statements  of  income,  common
stockholders  equity and  comprehensive  income,  and cash flows for each of the
years in the  three-year  period ended  December 31, 2004,  and our report dated
February  22,  2005  expressed  an  unqualified  opinion  on those  consolidated
financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD OF DIRECTORS AND STOCKHOLDERS
CALIFORNIA WATER SERVICE GROUP

     We have audited the accompanying  consolidated balance sheets of California
Water Service Group and  subsidiaries  as of December 31, 2004 and 2003, and the
related  consolidated  statements  of  income,  common  stockholders  equity and
comprehensive  income,  and cash  flows for each of the years in the  three-year
period ended December 31, 2004. These consolidated  financial statements are the
responsibility  of  the  management  of  California  Water  Service  Group.  Our
responsibility  is  to  express  an  opinion  on  these  consolidated  financial
statements based on our audits.

     We  conducted  our audits in  accordance  with the  standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain  reasonable  assurance about whether the
financial  statements  are free of  material  misstatement.  An  audit  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,  the consolidated  financial  statements  referred to above
present fairly, in all material  respects,  the financial position of California
Water Service Group and  subsidiaries  as of December 31, 2004 and 2003, and the
results  of their  operations  and their cash flows for each of the years in the
three-year  period ended  December 31, 2004, in conformity  with U.S.  generally
accepted accounting principles.

     We also have  audited,  in  accordance  with the  standards  of the  Public
Company  Accounting  Oversight Board (United States),  the  effectiveness of the
internal control over financial  reporting of California Water Service Group and
subsidiaries  as of December 31,  2004,  based on the  criteria  established  in
Internal  Control-Integrated  Framework  issued by the  Committee of  Sponsoring
Organizations of the Treadway  Commission  (COSO), and our report dated February
22, 2005 expressed an unqualified opinion on managements  assessment of, and the
effective operation of, internal control over financial reporting.
