Overview

     California Water Service Group (Company) provides water utility services to
customers in California, Washington, New Mexico, and Hawaii. The majority of the
business is regulated by the respective state's public utility  commission.  The
Company's  California water utility service operations  comprise the majority of
the business and  contributed 96% of revenues and 95% of net income in 2005. 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, water testing services, and a new Extended
Service  Protection  (ESP) Program  covering  repairs to the customer water line
between the meter and the home. Further information on the Company's  operations
may be found in the Company's  Form 10-K filed with the  Securities and Exchange
Commission  (SEC).  See page 68 of this Annual Report for  information on how to
obtain a copy of Form 10-K.

     The state regulatory entities governing the Company's regulated  operations
are referred to as  "Commission(s)" in this report.  Revenues,  income, and cash
flows are earned  primarily  through  delivering  potable water through pipes to
homes,  businesses,   industries,  and  public  authorities.  Rates  charged  to
customers for the regulated  business are determined by the  Commissions,  which
also set operating  and customer  service  standards.  The rates are intended to
allow  recovery of operating  costs and a reasonable  rate of return on invested
capital.

     Major risk factors affecting the financial  performance of the Company are:
extensive regulation,  decisions by state regulatory commissions, and changes in
laws and regulations; increased costs, such as electricity, not recoverable from
ratepayers;  operating  costs affected by increased  environmental  regulations;
lack of control over water supply;  inability to finance  capital  expenditures;
acquisitions,  divestitures,  or  restructuring;  failure and  circumvention  of
controls and  procedures;  and judgments and estimates  regarding  financial and
accounting matters. For additional information on "Risk Factors," see Item 1A of
the Form  10-K on file  with the SEC.  See  page 68 of this  Annual  Report  for
information on how to obtain Form 10-K.

     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  Commission 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
equity.  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 supplies and operations.

     For 2005,  net income was $27.2 million  compared to $26.0 million in 2004,
an increase of 4.6%.  Diluted earnings per share for 2005 were $1.47 compared to
$1.46 in 2004,  an increase  of 0.7%.  The  increase  in earnings  per share was
primarily  due to  higher  rates  approved  by  the  Commissions,  sales  to new
customers,  and  increased  gains  from  property  sales.  Partially  offsetting
increased earnings were decreased sales to existing customers due to wetter than
normal weather conditions, higher maintenance costs, higher depreciation, higher
income taxes,  and the dilutive  effect of having more weighted  average  shares
outstanding  than  the  prior  year.  The  Company  plans  to  continue  to seek
additional  rate  increases to recover its operating  cost increases and receive
reasonable returns on invested capital. For each of the five years subsequent to
2005, capital expenditures are expected to continue to increase generally at the
same rate as  inflation  and  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
requirements);   therefore,   the  Company  expects  to  fund  anticipated  cash
shortfalls  through a combination of debt and common stock offerings in the next
five years.

     In 2005  and  2004,  the  Company  received  many  different  types of rate
increases,  some of which  were  temporary  in  nature.  As such,  the growth in
earnings  due solely to rate relief in 2005 and 2004 is not expected to recur in
2006. A significant factor in 2006 affecting earnings will be the timing and the
amount of the General  Rate Case (GRC)  filings that are expected to be approved
in the second  quarter of 2006. See the "Rates and  Regulation"  section of this
report for more information on regulatory  activity occurring in 2004, 2005, and
through February 21, 2006.

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  Cal  Water  and  Utility
Services,  which serve 456,674 customers in 75 California communities through 26
separate  districts.  Of these 26 districts,  24 districts  are regulated  water
systems,  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  CPUC's  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 15,311 customers in the
Tacoma and Olympia areas. Washington Water's 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 6,480 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 537 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;  providing 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;  selling non-utility property;  and ESP. These activities are reported
below

Management's Discussion and Analysis of Results of Operations and
Financial Condition


operating net income on the income statement,  gross of income taxes; 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,  excluding  gain on sale of  non-utility
property, comprised 6% of the total net income in 2005.

     Rates  and   operations   for  regulated   customers  are  subject  to  the
jurisdiction of the respective  state's 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 the
opportunity 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 2005 was $27.2  million  compared to
$26.0  million in 2004 and $19.4  million in 2003.  Diluted  earnings per common
share were $1.47 in 2005, $1.46 in 2004, and $1.21 in 2003. The weighted average
number of common  shares  outstanding  used in the  diluted  earnings  per share
calculation was 18,402,000 in 2005,  17,674,000 in 2004, and 15,893,000 in 2003.
As explained  below, the increase in 2005 earnings per share resulted from these
primary  factors:  receiving rate relief on GRC filings and balancing  accounts;
customer  growth;  and  gains  on  sale  of  non-utility  properties.  Partially
offsetting  these  positive  factors  were:  higher  maintenance  costs;  higher
depreciation  costs;  decreased water usage by existing  customers due to wetter
than  normal  weather;   higher  income  taxes;   and  increased  common  shares
outstanding.

     At the January 2006 meeting,  the Board of Directors declared the quarterly
dividend,  increasing it for the 39th consecutive  year. The quarterly  dividend
was raised from $0.2850 to $0.2875 per common share, an annual rate of $1.15 per
common share.  Dividends  have been paid for 61  consecutive  years.  The annual
dividends paid per common share in 2005,  2004, and 2003 were $1.14,  $1.13, and
$1.125, 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.  In its long-term  consideration,  the
Board of  Directors  plan to  achieve a payout  ratio in the  range of 60%.  The
dividend  payout ratio was 78% in 2005, 77% in 2004, and 93% in 2003, an average
of 83% over the three-year period.

     Operating Revenue Operating revenue in 2005 was $320.7 million, an increase
of $5.1  million,  or 1.6%,  over  2004.  Operating  revenue  in 2004 was $315.6
million, an increase of $38.5 million, or 14%, above 2003. The estimated sources
of changes in operating revenue were:

     Overall,  temperatures  in our service  areas for 2005 were  comparable  to
2004; however, rainfall was significantly higher, particularly in the first half
of the year.  Southern  California  had one of its wettest years on record.  For
2004,  rainfall  was lower  than 2003 in our  California  service  areas,  which
positively  impacted the Company's  revenues and earnings.  For Washington Water
service  areas,  rainfall was  significantly  lower in 2005. As a result,  state
officials mandated water conservation,  resulting in decreased revenues compared
to 2004.

     In 2005, rate relief  increased  revenues by $12.2 million.  See the "Rates
and  Regulation"  section of this  report  for more  information  on  regulatory
activity occurring in 2004, 2005, and through February 21, 2006.

     The number of customers  in 2005  increased  by 5,846,  or 1.2%,  from 2004
levels.  This  increase  includes 645  customers in New Mexico,  37 customers in
Hawaii,  296  customers  in  Washington,   and  4,868  additional  customers  in
California.  Approximately 350, 270, and 169 were added through  acquisitions in
New Mexico,  California,  and Washington,  respectively,  with the remaining new
customers  resulting from growth in existing  service areas.  In 2004,  customer
growth was 6,733, which included approximately 1,700 new customers added through
an acquisition in New Mexico.

     Water  Production  Expenses  Water  production  expenses,  which consist of
purchased water,  purchased power, and pump taxes,  comprise the largest segment
of total operating expenses.  Water production costs accounted for 41.2%, 43.5%,
and 44.2% of total operating costs in 2005,  2004, and 2003,  respectively.  The
rates  charged for wholesale  water  supplies,  electricity,  and pump taxes are
established  by various  public  agencies.  As such,  these rates are beyond our
control.  The table below  provides  the amount of  increases  (decreases),  and
percentage changes in water production costs during the past two years:

     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 differences between wholesale suppliers. For 2005, the
$2.2  million  decrease  in  purchased  water  costs is due to a 4%  decrease in
quantities purchased,  partially offset by overall higher wholesale water rates.
On  an  overall  blended  basis,  wholesale  water  rates  increased  1.4%  on a
cost-per-million-gallon  basis. In 2004,  purchased  water expenses  included an
additional  adjustment  of $0.9 million,  which  related to the  settlement of a
meter malfunction issue in the Stockton  district.  Purchased power expenses are
affected  by the  quantity  of water  pumped  from wells and moved  through  the
distribution  system,  rates  charged by electric  utility  companies,  and rate
structures applied to usage during peak and non-peak times of the day or season.
The  purchased  power  expense  decrease of $1.3  million was  primarily  due to
decreased  well  production.  Pump  taxes  were the same in 2005 as in 2004,  as
higher rates offset the decreased pumping.

     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.



Management's Discussion and Analysis of
Results of Operations and Financial Condition


     During 2005, administrative and general expenses increased $1.6 million, or
3.4%,  compared to 2004.  Payroll expense charged to administrative  and general
expense remained constant due to a decrease in the number of employees offset by
higher wages. Employee/retiree health care costs increased $1.6 million, or 19%,
due to increased  medical claims.  The Company is  self-insured  and experienced
several  large-dollar  medical claims (claims over  $200,000),  which  primarily
caused the  increase.  Increases  in other  costs,  including  legal and outside
services,  were substantially  offset by a decrease in workers'  compensation of
$1.1  million,  which was due to fewer  claims and a refund  from the  Company's
stop-loss insurance carrier.

     During 2004, administrative and general expenses increased $6.1 million, or
15%,  compared to 2003.  Payroll expense charged to  administrative  and general
expense 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. The Company also experienced
higher costs for workers' compensation,  general liability claims, and insurance
premiums, which increased $1.3 million, or 40%. Higher expenses were incurred to
comply with  Sarbanes-Oxley  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.

     Other  Operations  Expenses The  components  of other  operations  expenses
include payroll, material and supplies, and contract services costs of operating
the  regulated  water  systems,   including  the  costs  associated  with  water
transmission and distribution,  pumping, water quality, meter reading,  billing,
and operations of district offices.

     For 2005, other operating  expenses  increased $0.1 million,  or 0.2%, from
2004.  Payroll costs charged to other operating expenses increased $0.7 million,
or 2.2%,  due to general wage  increases.  Expenses were offset by a decrease of
$0.5 million,  or 64%, for changing the process for disposing of by-products for
the  Bakersfield  Treatment  Plant.  Other expense  elements  contributed to the
balance of the change, but none were individually significant.

     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 increases in the number of employees.
Other major cost increases were operations of the Bakersfield Treatment Plant of
$0.6 million and additional  lease cost 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.

     Maintenance  Maintenance  expenses increased $2.0 million,  or 15%, in 2005
compared to 2004. For 2004,  maintenance expenses increased $0.5 million, or 4%,
compared to 2003. In 2005, maintenance expense increased due to repairs of water
treatment  equipment,  water  main,  and  wells.  In  2004,  expenses  increased
primarily for service line  repairs,  which are pipes from the main to the meter
box.

     Depreciation and Amortization  Depreciation and amortization  increased due
to the level of Company-funded  capital  expenditures and a higher  depreciation
rate authorized by the CPUC.

     Income Taxes For 2005, income taxes increased $2.9 million. The significant
items include  provision for taxes on gain on sale of non-utility  properties of
$0.9 million,  provision for taxes on increased  income from  operations of $0.5
million,  and $0.7  million  for the  reversal of federal  tax  depreciation  on
pre-1982 assets, which was previously flowed-through to ratepayers.  The Company
anticipates  the  reversal of federal  tax  depreciation  on pre-1982  assets to
continue in future years;  however, its effect on the Company's tax provision is
uncertain due to the offsetting  flow-through of state tax  depreciation,  which
continues to increase with capital additions.

     Property and Other Taxes For 2005, expenses increased $1.1 million, or 10%,
compared to 2004. For 2004,  expenses  increased $1.0 million,  or 9%. 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,  antenna site leases,  water rights
brokering,  and design and construction services. For 2005, non-regulated income
increased $0.5 million,  or 18%, compared to 2004, with increases primarily from
O&M contracts,  antenna site leases,  and reduced  expenses  related to business
development.  For 2004,  non-regulated  income increased  compared to 2003, with
increases  primarily  from O&M and antenna  site leases  offset by  decreases in
water rights brokerage income.  Water rights brokerage income is sporadic and is
affected by market  opportunities and price volatility.  See Note 3 of the Notes
to Consolidated Financial Statements for additional information.

     Gain  on  Sale  of  Non-Utility   Property  For  2005,  pretax  gains  from
non-utility  property sales were $2.2 million compared to insignificant gains in
2004. The 2005 gains were primarily from three  properties sold in the Los Altos
and Chico districts. Earnings and cash flow from these transactions are sporadic



and may or may not continue in future periods, depending upon market conditions.
The Company has other non-utility  properties that may be marketed in the future
based on real estate market conditions.

     In 2005,  interest expenses decreased by $0.1 million, or 1%, as there were
no short-term  borrowings  in 2005. In 2004,  interest  expense  increased  $0.3
million, or 2%, due to a decrease in capitalized interest, which was a result of
lower value of capitalized projects. Capitalized interest in 2005 was comparable
to 2004. See the "Liquidity and Capital Resources" section for more information.

Rates and Regulation

     The state  regulatory  commissions  have plenary  powers  setting rates and
operating standards.  As such, state commission  decisions  significantly impact
revenues,  earnings,  and cash flow of the Company.  The amounts  discussed  are
generally annual amounts,  unless specifically  stated, and the financial impact
to  recorded  revenue  is  expected  to occur over a  12-month  period  from the
effective date of the decision.  In California,  water utilities are required to
make several  different  types of filings.  Most filings  result in rate changes
that remain in place  until the next GRC. As  explained  below,  surcharges  and
surcredits to recover balancing and memorandum  accounts as well as the catch-up
are temporary rate changes, which have specific time frames for recovery.

     General Rate Cases (GRCs)

     GRCs,  step rate  increase  filings,  and offset  filings  change  rates to
amounts  that will remain in effect  until the next GRC. The CPUC follows a rate
case plan,  which  requires Cal Water to file a GRC for each of its 24 regulated
operating  districts every three years.  In a GRC proceeding,  the CPUC not only
considers the utility's  rate-setting  requests,  but may consider  other issues
that affect the utility's rates and  operations.  Effective in 2004, Cal Water's
GRC schedule  was shifted from a calendar  year to a fiscal year with test years
commencing  July 1. The CPUC is  generally  required  to issue its GRC  decision
prior to the first day of the test year or authorize interim rates. As such, Cal
Water's GRC decisions,  which prior to 2005 were generally  issued in the fourth
quarter, are expected to be issued in the second quarter of each year. Cal Water
expects decisions on the eight GRCs filed in August of 2005 to be issued in June
of 2006.

     Step Rate Increases

     Between GRC filings,  utilities may file step rate  increases,  which allow
the utility to recover cost increases,  primarily from inflation and incremental
investment,  during the second and third years of the rate case cycle.  However,
step rate increases are subject to a weather-normalized earnings test. Under the
earnings test, the CPUC may reduce the step rate increase to prevent the utility
from earning in excess of the authorized rate of return for that district.  Step
rate increases, which were previously approved in January, should be approved in
July under the new rate case schedule.

     Offset Filings

     In addition,  utilities are entitled to file offset filings. Offset filings
may be filed to adjust  revenues for  construction  projects  authorized in GRCs
when the plant is placed in service or for rate  changes  charged to the Company
for  purchased   water,   purchased  power,  and  pump  taxes  (referred  to  as
"offsettable expenses").  Such rate changes approved in offset filings remain in
effect until a GRC is approved.

     Surcharges and  Surcredits

     Surcharges  and  surcredits,  which are  usually  effective  for a 12-month
period,  are  authorized  by the CPUC to recover the  memorandum  and  balancing
accounts  under- and  over-collections  usually  due to  changes in  offsettable
expenses. However, significant under-collections may be authorized over multiple
years.  Currently,  filings to recover  offsettable  expenses  are  subject to a
non-weather-adjusted earnings test. Under the earnings test, the CPUC may reduce
recovery of an offsettable expense to prevent the utility from earning in excess
of its authorized rate of return. Typically, an expense difference occurs during
the time  period  from when an  offsettable  expense  changes and the Company is
allowed to adjust its water  rates.  Expense  changes  for this  regulatory  lag
period,  which is about two months,  are booked into  memorandum  and  balancing
accounts for later recovery.  However,  in 2001, the CPUC changed its procedures
and did not  permit  water  companies  to  immediately  adjust  water  rates for
offsettable  expense changes.  As a result, the amount accrued in memorandum and
balancing accounts, due primarily to the major increases in electric power costs
in 2001,  grew to $9.2 million at the end of 2004.  Beginning in November  2002,
the  CPUC  allowed  water  companies  to file for  recovery  of  memorandum  and
balancing account under-collections  subject to a non-weather-adjusted  earnings
test.  However,  the  Company  did  not  receive   authorization  to  collect  a
significant portion of the under-collection from its ratepayers until the fourth
quarter of 2004.

     Timing of Expense  Balancing and  Memorandum  Accounts

     The Company  does not record an asset (or  liability)  for the recovery (or
refund) of expense balancing or memorandum accounts in its financial  statements
as revenue (refunds), nor as a receivable (or payable), until the CPUC and other
regulators have  authorized  recovery and the customer is billed.  Therefore,  a
timing  difference  may occur  between when costs are recorded as an expense and
the associated revenues are received (or refunds are made) and booked.

     During 2005 and 2004, no rate filings were approved for  Washington  Water.
In 2004 and 2003, Cal Water collected a catch-up  surcharge for its 2001 GRC. In
Cal Water's 2001 GRC,  the  CPUC-authorized  effective  date for rates was April
2003;  however,  a final  decision was not approved until  September  2003. As a
result, the Company was authorized to collect  approximately $4.5 million of the
revenue  not billed  between  April and  September  of 2003.  In 2005,  revenues
dropped  compared to the prior year,  due in part to the  discontinuance  of the
catch-up  surcharge.  In 2005 and 2004,  the Company's  revenues were  favorably
impacted by approximately $3.9 million and $0.4 million, respectively,  from the
net recovery of memorandum and balancing accounts.

1. Step rate increases were granted in compliance with D.03-09-021, D.03-10-005,
D.04-04-041, and D.04-09-038.

2. Step rate increases were granted in compliance with D.03-09-021, D.03-10-005,
D.04-04-041, D.04-07-033, and D.04-09-038.

3. Step rate increases were granted in compliance with D.01-08-039, D.03-09-021,
and D.03-10-005.

4. Various advice letters are approved in aggregate.




     The Company  expects that the net effect of surcharges and surcredits  will
reduce revenue by  approximately  $2.3 million in 2006,  assuming similar usage.
The  estimated  impact of rate changes  compared to the prior years is listed in
the following table:

     Remaining Unrecorded Balances from Previously  Authorized Balancing Account
Recoveries/Refunds

     For the balancing accounts  authorized in May 2004, the amount remaining to
be refunded  as of December  2005 was $0.2  million and  December  2004 was $0.6
million. The balance is expected to be refunded by May 2006.

     For the  balancing  accounts  authorized  in  September  2004,  the  amount
remaining  to be  collected  in rates as of December  2005 was $0.2  million and
December 2004 was $0.3 million.  The balance is expected to be recovered by June
2006.

     For the balancing  accounts  authorized in the fourth  quarter of 2004, the
net amount  remaining  to be  collected  in rates as of  December  2005 was $3.1
million and December  2004 was $8.3  million.  The net balance is expected to be
fully recovered by January 2008.

     For the  balancing  accounts  authorized  in  September  2005,  the  amount
remaining  to be collected in rates as of December  2005 was $0.8  million.  The
balance is expected to be recovered by the third quarter of 2006.

     The total amount of  unrecorded,  under-collected  memorandum and balancing
accounts  was $2.6 million and $8.5  million,  as of December 31, 2005 and 2004,
respectively.  Included in this amount, Cal Water has pending memorandum account
filings for 2005 and  previously  authorized  balancing  accounts  approved  for
collection as stated above.

     Pending  Filings as of February 21, 2006

     Cal Water has pending its 2005 GRC filings  covering eight  districts.  Cal
Water  expects  decisions  regarding  its 2005 GRCs to be  issued in the  second
quarter of 2006. The amount  requested in the 2005 GRCs is  approximately  $10.6
million in 2006/2007,  $5.5 million in 2007/2008, and $5.5 million in 2008/2009.
The  amounts  granted  may vary 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  GRCs  also  requested  the  CPUC  to  consider  several
modifications to CPUC rate-setting procedures.  The GRCs request a water revenue
adjustment  mechanism  that would  allow the Company to recover  (refund)  water
revenues  when actual water sales are below  (above)  adopted water sales in the
GRCs.  This proposal  would  decouple the Company's  revenues from  conservation
efforts and inaccurate weather  forecasts,  putting in place a mechanism similar
to that employed by California's  investor-owned  electric  utilities.  The GRCs
also  request a  full-cost  balancing  account  that would  allow the Company to
recover  changes in source of supply mix as well as price  changes under current
procedures.  The Company requested a rate base equalization  account to minimize
the impact on rates of large capital  projects in small water systems.  Finally,
the Company  requested that the Commission  adjust its authorized rate of return
if modifications are not adopted to change certain rate-setting procedures.  The
Company is unable to predict the timing and final outcome of the filings at this
time.

     2006 Regulatory Activity

     In accordance  with the rate case plan, Cal Water will file a GRC for eight
districts in May of 2006.  At this time,  Cal Water does not know the amounts to
be requested.  In January 2006,  the Company was granted step rate increases for
13 districts and was  authorized an increase of $1.9 million.  In February 2006,
Cal Water  received  authorization  to recover  (refund)  various  balancing and
memorandum accounts.  Memorandum account decision AL1734A will be collected over
a 36-month  period.  Cal Water also  intends to file for step rate  increases in
July for eight districts. Cal Water is authorized to request up to $5.5 million;
however, the request may be adjusted downward by the  weather-adjusted  earnings
test.


Management's Discussion and Analysis of
Results of Operations and Financial Condition


     In the first quarter of 2006, Cal Water will file an advice letter to allow
it to track in a  memorandum  account  additional  funding  associated  with its
retiree health care plan.  Currently,  Cal Water funds and  recognizes  expenses
associated  with the plan on a pay-as-you-go  basis.  The excess expense between
pay-as-you-go and accrual during the employees' expected service period has been
recognized as a regulatory  asset. As of December 31, 2005, the regulatory asset
was approximately $9.8 million. Cal Water intends to increase its funding so the
plan is funded during the employee's  service period.  Cal Water has established
two Voluntary Employee  Beneficiary  Associations (VEBAs) to allow for increased
funding and a current-period  income tax deduction.  Cal Water will also file an
application  to recover its regulatory  asset.  Cal Water believes that the CPUC
will recognize in rates the recovery of the regulatory  asset and the additional
funding of the plan. If the CPUC does not permit the Company to recover the full
amount of its regulatory  asset, the regulatory asset, to the extent not allowed
in recovery,  will be written  off. If the CPUC does not approve the  memorandum
account,  the  Company  will  not be able to  recover  the  higher  expenses  of
approximately  $0.6 million per year until such  expenses are  recognized in its
GRC applications.

     Washington  Water is planning to submit a rate filing in the first  quarter
of 2006, but has not filed as of the date of this report.

     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
Water's 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. The
decision also ordered Cal Water to file an  application  for approval to replace
the operations  and customer  centers in its Chico district and for treatment of
the gain on sale proceeds.

     D.03-09-021  also directed the CPUC staff to file a detailed  report on its
review of Cal Water's application.  On January 11, 2005, the Office of Ratepayer
Advocates  (ORA) issued a report  expressing  its opinion that Cal Water had not
proven that  surplus  properties  sold since 1996 were no longer  necessary  and
useful to provide utility service.  ORA also recommended that Cal Water be fined
$160,000 and that gains from property sales should generally benefit ratepayers.
During the period  under  review,  Cal  Water's  cumulative  gains from  surplus
property sales were $19.2 million.

     On December 1, 2005, the CPUC issued its  D.05-12-002.  This decision found
that Cal Water appropriately reclassified all properties as non-utility property
prior to being  sold and the  criteria  Cal Water  followed  to  reclassify  its
properties  were  reasonable and consistent  with the  requirements of the CPUC.
Since the properties were properly reclassified, the CPUC found that approval of
the property sales was not required and no penalty was  warranted.  Furthermore,
the decision  found that Cal Water should be allowed to include in rate base the
full cost of the Chico customer center.

     Although  the  decision  concluded  that all gains for the  property  sales
qualified  for  reinvestment  in  accordance  with the  Infrastructure  Act, the
decision deferred the rate-making issue regarding  treatment of sale proceeds to
its Order  Instituting  Rulemaking  (R.)  04-09-003.  On November  5, 2005,  the
Commission  issued its draft decision  regarding the allocation of proceeds from
the sale of utility assets.  The draft decision states that the CPUC has limited
discretion in how it allocates between  ratepayers and utility  shareholders the
gains on sale of real property that meet the criteria in the Infrastructure Act,
provided that water utilities reinvest the proceeds in new water infrastructure.
If the draft decision is adopted,  the Company will be entitled to earn its full
authorized return on the proceeds  reinvested in utility plant from the gains on
surplus property sales that were under review.

     Based on D.05-12-002 and the draft decision, Cal Water has not recorded any
adjustments in its financial  statements.  Cal Water does not know when the CPUC
will issue its decision in the matter of R.04-09-003. If the CPUC rules that any
portion of the property sales should be allocated to the ratepayers, Cal Water's
rate base could be reduced,  which would lower future revenues,  net income, and
cash flows.

     Elimination of the Earnings Test on Balancing Accounts

     On January 23,  2006,  the CPUC issued a draft  decision to suspend,  until
further  notice,  the   non-weather-adjusted   earnings  test  that  applies  to
memorandum and balancing  account recovery for water utilities.  The elimination
of the earnings test should  significantly  improve Cal Water's  opportunity  to
earn its  authorized  rate of return.  Over the past three years,  Cal Water has
been unable to recover $3.5 million in offsettable expenses.  The draft decision
does not address the weather-adjusted  earnings test, which is required for step
rate increases.


Water Supply

     Our  source  of  supply  varies  among  our  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   Water  service  areas  receive
precipitation in all seasons,  with the heaviest amounts during the winter.  New
Mexico Water's  rainfall is heaviest in the summer monsoon season.  Hawaii Water
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  accumulation  during  the  2005-2006  water  year has been  above
average.  Precipitation in the prior year was also above average.  Water storage
in  California's  reservoirs  at the end of 2005  was at  above-average  levels.
Management  believes that supply pumped from underground  aquifers and purchased
from wholesale  suppliers  will be adequate to meet customer  demand during 2006
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 in compliance with
the new Environmental Protection Agency (EPA) standard related to arsenic, which
became 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 equity.  Short-term bank borrowings were zero at December 31, 2005 and 2004.
Cash and cash  equivalents  were $9.5  million at  December  31,  2005 and $18.8
million at December  31,  2004.  In January  2005,  the Company  received a $7.2
million tax refund due to federal bonus  depreciation  allowed one time in 2004.
The  Company  does not  expect to  receive a similar  refund in 2006.  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 or cash equivalent  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  that  outstanding
balances  be below  $10  million  for a 30-day  consecutive  period  during  any
12-consecutive-month  period.  In addition,  the  agreement  requires  debt as a
percentage of total  capitalization to be less than 67%. The Company has met all
covenant  requirements and is eligible to use the full amount of the commitment.
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, 2005, 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, 2005,  there were no borrowings  against the
credit facility.

     A $10 million credit  facility  exists for the Company,  Utility  Services,
Washington  Water,  New Mexico Water,  and Hawaii Water. 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  that  outstanding
balances  be below  $5  million  for a  30-day  consecutive  period  during  any
12-consecutive-month  period.  In addition,  the  agreement  requires  debt as a
percentage of total  capitalization to be less than 67%. The Company has met all
covenant  requirements and is eligible to use the full amount of the commitment.
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


Management's Discussion and Analysis of Results of Operations
and Financial Condition


credit were outstanding at December 31, 2005.  Interest is charged on a variable
basis and fees are charged for unused  amounts.  As of December 31, 2005,  there
were no borrowings against the credit facility.

     Credit Ratings

     Cal Water's first  mortgage  bonds are rated by Moody's  Investors  Service
(Moody's) and Standard & Poor's (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 2005, management met separately
with the two credit rating  agencies,  and both agencies have  maintained  their
ratings of A2 for Moody's  and A+ for S&P as of the filing date of this  report.
The last time ratings were changed was in February  2004,  when Moody's issued a
report lowering Cal Water's 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,  both agencies 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 equity offerings.  Management
believes the Company would be able to meet financing  needs even if ratings were
downgraded,  but a rating  change could 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. The Company did not issue any
significant long-term debt or additional stock in 2005.

     In June 2004,  the Company issued  1,409,700  shares of its common stock at
$27.25 per share.  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 are  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  had been  applied  against this
authorization as of December 31, 2005.

     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.  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.

     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 Notes 8 and 9 of the Notes to 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  brokerage 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.  Our transfer agent operates the Plan and purchases shares
on the open market to provide shares for the Plan.

     2006 Financing Plan

     The Company's 2006 financing plan includes  raising  approximately  $40-$50
million  of new  capital.  The plan  includes  issuance  of  long-term  debt and
additional  equity,  although this may change depending on a variety of factors.
Beyond  2006,  management  intends to fund  capital  needs  through a relatively
balanced approach between long-term debt and equity.

     Contractual Obligations

     The  Company's  contractual  obligations  are  summarized  in the following
table.  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. System and
Office  leases  include  obligations  associated  with leasing water systems and
rents for office space.

     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 our control. The amount paid annually
to the  wholesale  suppliers  is  charged  to  purchased  water  expense  on our
statement of income.  Most contracts do not require  minimum annual payments and
vary with the volume of water purchased.

     The  Company  has a  contract  with the Santa  Clara  Water  District  that
contains  minimal  purchase  provisions.  The contract  payment  varies with the
volume of water purchased above the minimal level.  Management plans to continue
to purchase and use at least the minimum water  requirement  under this contract
in the future.  The total paid under this contract was $4,763 in 2005, $4,610 in
2004, and $4,452 in 2003.

     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 $4,300 in 2005,  $4,392 in
2004, and $3,779 in 2003. Pricing under the contract varies annually.  Estimated
annual contractual  obligations in the table above are based on the same payment
levels as 2005.  Future  increased  costs by SEWD are expected to be offset by a
decline in the  allocation of costs to the Company,  as other  customers of SEWD
are expected to receive a larger  allocation  based upon growth of their service
areas.

     On September  21,  2005,  the Company  entered into an agreement  with Kern
County  Water  Agency  (Agency)  to  obtain  treated  water  for  the  Company's
operations.  The term of the  agreement  is to  January  1,  2035,  or until the
repayment of the Agency's bonds (described below) occurs. Under the terms of the
agreement,  the Company is  obligated  to purchase  20,500  acre-feet of treated
water per year. The Company is obligated to pay a Capital  Facilities Charge and
a Treated Water Charge,  both of which will be expensed as invoiced,  regardless
of whether it can use the water in its  operation,  and is  obligated  for these
charges  even if the  Agency  cannot  produce an  adequate  amount to supply the
20,500 acre-feet in the year. (This agreement  supersedes a prior agreement with
Kern County Water  Agency for the supply of 11,500  acre-feet of water per year.
The total paid, under the prior agreement,  was $3,288 in 2005,  $3,308 in 2004,
and $2,691 in 2003.)

     Three other parties, including the City of Bakersfield,  are also obligated
to purchase a total of 32,500 acre-feet per year under separate  agreements with
the Agency.  Furthermore,  the Agency has the right to proportionally reduce the
water supply provided to all of the  participants if it cannot produce  adequate
supplies.  The  participation of all parties in the transaction for expansion of
the Agency's facilities, including the Water Purification Plant, purchase of the
water,  and payment of interest  and  principal on the bonds being issued by the
Agency to finance the transaction,  is required as a condition to the obligation
of the Agency to proceed with  expansion of the Agency's  facilities.  If any of
the other  parties does not use its  allocation,  that party is obligated to pay
its contracted amount.

     The Agency is  planning to issue bonds to fund the project and will use the
payments  of the  Capital  Facilities  Charges  by the  Company  and  the  other
contracted  parties to meet the Agency's  obligations  to pay interest and repay
principal on the bonds. If any of the parties were to default on making payments
of the Capital  Facilities  Charge,  then the other parties are obligated to pay
for the  defaulting  party's  share on a pro-rata  basis.  If there is a payment
default by a party and the  remaining  parties have to make  payments,  they are
also entitled to a pro-rata share of the defaulting party's water allocation.

     The  Company  expects  to use all its  contracted  amount  of  water in its
operations  every year. In addition,  if the Company were to pay for and receive
additional amounts of water due to a default of another participating party, the
Company  believes it could use this additional  water in its operations  without


Management's Discussion and Analysis of Results of Operations
and Financial Condition


incurring substantial incremental cost increases. If additional treated water is
available, all parties have an option to purchase this additional treated water,
subject to the Agency's right to allocate the water among the parties.

     The  total   obligation  of  all  parties,   excluding   the  Company,   is
approximately $108 million to the Agency.  Based on the  creditworthiness of the
other participants,  which are government entities,  it is believed to be highly
unlikely  that the  Company  would be  required  to  assume  any  other  party's
obligations under the contract due to its default.  In the event of default by a
party,  the  Company  would  receive  entitlement  to the  additional  water for
assuming the additional obligation.

     Once the project is  complete,  the Company is  obligated  to pay a Capital
Facilities  Charge and a Treated Water Charge that  together  total $4.7 million
annually,  which equates to $231 per acre-foot.  Annual payments of $2.0 million
for the Capital  Facilities  Charge will begin when the Agency  issues  bonds to
fund the project.  Some of the Treated  Water Charge of $2.8 million is expected
to begin July 1, 2007, when a portion of the planned  capacity is expected to be
available. The expanded water treatment plant is expected to be at full capacity
by July 1, 2008,  and at that time,  the full annual  payments  of $4.7  million
would be made and continue through the term of the agreement. Once treated water
is being  delivered,  the Company will also be obligated  for its portion of the
operating  costs;  that portion is currently  estimated to be $69 per acre-foot.
The actual amount will vary due to variations  from  estimates,  inflation,  and
other changes in the cost  structure.  The Company's  overall  estimated cost of
$300 per acre-foot is less than the estimated cost of procuring  untreated water
(assuming water rights could be obtained) and then providing treatment.

     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  $77.6  million,  $50.4
million, and $53.9 million in 2005, 2004, and 2003, respectively.  A majority of
capital expenditures was associated with mains and water treatment equipment.

     For 2006, Company-funded capital expenditures are budgeted at approximately
$85 million. The 2006 capital budget is the same as the 2005 capital budget. For
the years 2006  through  2010,  capital  expenditures  are  estimated at $75-$85
million per year,  and will be primarily for mains,  related water  distribution
equipment, water quality equipment, and pumping.

     Other  capital  expenditures  are funded  through  developer  Advances  and
Contributions  in Aid of  Construction  (non-Company  funded).  The  expenditure
amounts were $16.9 million,  $18.2 million, and $20.4 million in 2005, 2004, and
2003, respectively.  The changes from year to year reflect expansion projects by
developers in our service areas.

     Management expects the Company to incur non-Company funded  expenditures in
2006.  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 our commencing construction work,
or the developers may construct the facilities themselves and deed the completed
facilities to the Company.  Funds are generally 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. 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 2005, common  stockholders'  equity increased by $6.3
million,  due  primarily to an increase in retained  earnings.  In 2004,  common
stockholders'  equity increased $43.1 million, or 18%, due primarily to earnings
and the issuance of new shares of common stock.  The long-term debt decreased by
$0.7  million,  due  primarily  to sinking  fund  payments.  See the  "Long-Term
Financing" section above for additional information.

     Total  capitalization  at  December  31,  2005 was  $571.5  million  and at
December 31, 2004 was $565.9 million.  The Company intends to issue common stock
and long-term debt to maintain the Company's current  capitalization  structure,
taking into account  reinvestment of earnings above  dividends.  At December 31,
capitalization ratios were:

                                         2005     2004
                                         ----     ----
Common equity                           51.4%    50.8%
Preferred stock                          0.6%     0.6%
Long-term debt                          48.0%    48.6%


     The return (from both  regulated and  non-regulated  operations) on average
common equity was 9.3% in 2005 compared to 9.8% in 2004.

     Acquisitions

     Although there were no significant  acquisitions in the periods  presented,
the following acquisitions were completed in 2005 and 2004:

     In April 2005,  the Company  acquired  the water  system  assets of the Los
Trancos  Water  District for $125,000 in cash.  The Los Trancos water system and
its 270 customers were merged into Cal Water's Bear Gulch district. The purchase
price was  approximately  equal to rate base and no goodwill was recorded in the
transaction.

     In June 2005,  the Company  acquired the water system  assets of Gamble Bay
for $370,000.  The Company  assumed net  liabilities of $336,000 and the balance
was paid in cash. The Company merged the water system and its 169 customers into
Washington  Water.  The Company  recorded an acquisition  adjustment of $18,000,
which it believes will be included in rate base. As such,  the purchase price is
approximately equal to rate base and no goodwill was recorded.

     In June 2005,  the Company  acquired the water system assets of the Cypress
Gardens Water Company for $312,000 in cash.  The Company merged the water system
and its 350 customers into New Mexico Water. The purchase price is approximately
equal to rate base and no goodwill was recorded.

     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
NUC's  stock  and  merged  it into New  Mexico  Water.  Revenue  for NUC for the
eight-month  period  in 2004 was $0.4  million  and net  income  was  zero.  The
purchase price is approximately  equal to rate base and an immaterial  amount of
goodwill was recorded in the transaction.

     Real Estate Program

     The  Company  owns a  certain  amount  of real  estate.  From time to time,
certain  parcels are deemed  unnecessary  for and are not used 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  pretax gains of $2.2 million in 2005,  minimal
pretax gains were  recorded in 2004,  and $4.6 million was recorded in 2003.  As
sales are dependent on real estate market conditions,  future sales, if any, may
or may not be at prior year levels.  As discussed in the "Rates and  Regulation"
section,  future  sales may be  impacted  by the CPUC  ruling in its  proceeding
regarding sales of utility assets.

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  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  historic  experience  and an
understanding of current facts and  circumstances.  A summary of our significant
accounting  policies is listed in Note 2 of the Notes to Consolidated  Financial
Statements  and  other  Notes  provide  additional  information.  The  following
sections  describe  the level of  subjectivity,  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  Commission of that state. Under SFAS No.
71, a  utility  may  defer  certain  costs of  providing  services  if the rates
established  by its  regulators  are designed to recover the utility's  specific
costs and the economic  environment gives reasonable  assurance that those rates
can be charged and  collected  throughout  the periods  necessary to recover the
costs.  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 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
was no such asset  impairment  as of December 31, 2005.  Additional  information
relating to regulatory  assets and liabilities are listed in Note 2 of the Notes
to Consolidated Financial Statements.

     Unbilled Revenue

     Unbilled revenue is estimated for metered  customers for water used between
the last reading of the customer's  meter and the end of the accounting  period.
This  estimate is based on the usage from the last bill to the  customer,  which


Management's Discussion and Analysis of Results of Operations
and Financial Condition


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 (offsettable  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 and associated revenues are recognized.  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 "offsettable expenses" because under certain circumstances,  they
are recoverable from customers in future offset rate increases.  During 2004 and
2005,  the  CPUC  gave  approval  to  charge  customers  for a  portion  of  the
offsettable expenses.  Additionally,  the Company may file with the CPUC for its
offsettable  expenses  incurred  in  2005.  The  amounts  requested  may  not be
ultimately  collected  through  rates,  as amounts may be disallowed  during the
review process or subject to a  non-weather-adjusted  earnings  test.  While the
adjustments  would not impact previously  recorded amounts,  the adjustments may
change future  earnings and cash flows. At this time, the Company cannot predict
the actual recovery  (refund)  associated with 2005  offsettable  expenses to be
requested in 2006. (See "Rates and Regulation.")

     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
management's view, a valuation  allowance was not required at December 31, 2005.
Detailed schedules relating to income taxes are provided in Note 11 of the Notes
to Consolidated Financial Statements.

     Employee Benefit Plans The Company incurs costs associated with its pension
and  postretirement  health care benefit 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 plan's
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, 2005,
51.9% of the assets were  invested in domestic  equity  mutual  funds,  11.7% in
foreign equity mutual funds, and 36.4% in bond funds. Based on the market values
of the  investment  funds for the year ended December 31, 2005, the total return
on the pension  plan assets was 6.0%.  For 2004 and 2003,  returns  were 13% and
19%,  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 2005,  management  estimated the discount rate at 5.60%,
which  approximates  the  average  return  on  long-term  corporate  bonds as of
year-end.  Using the interest  rate curve  developed by Citigroup as of December
31, 2004 and 2005,  the  equivalent  level  discount rates were 5.74% and 5.58%,
respectively.  Accordingly,  the  discount  rate was  lowered in 2005 from 6% to
5.60%.  Management  assumed the rate of  compensation to increase 3% in its 2005



calculation. 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 Note 12 of the Notes
to Consolidated Financial Statements.

     Workers' Compensation,  General Liability,  and Other Claims The Company is
self-insured  for a portion  of  workers'  compensation  and  general  liability
claims.  Excess  amounts  are  covered  by  insurance  policies.   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. 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  Note  15 of the  Notes  to  Consolidated  Financial
Statements,  as these did not  qualify for  recording  under SFAS No. 5 or other
accounting standards. If management's assessment is incorrect, these items could
have a material impact on the financial  condition,  results of operations,  and
cash flows of the Company.

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 its 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 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  rates were to  increase,  management  believes  customer  rates  would
increase accordingly,  subject to Commission approval in future GRC filings. 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. For example, prior
to 2004, the Company believes its stock price was adversely  affected by analyst
reports,  which stated the Company's  earnings were  negatively  impacted by the
delays of certain  CPUC  decisions.  An adverse  change in the stock price could
make issuance of common stock less attractive in the future.

     Stock Market  Performance  Risk The Company's stock price could be impacted
by changes in the general 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  period  reported  are  described  in Note 2 of the  Notes to
Consolidated Financial Statements.

     As of the  filing  date,  there  were no  other  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.

Note 1. Organization and Operations

     California Water Service Group (Company) is a holding company that provides
water utility and other related services in California,  Washington, New Mexico,
and Hawaii  through its wholly  owned  subsidiaries.  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  state's  regulatory  commissions  (jointly
referred  to as  the  Commissions).  CWS  Utility  Services  (Utility  Services)
provides non-regulated water utility and utility-related services. At Cal Water,
as of December  31,  2005,  there were 566 union  employees  covered by two-year
agreements  with  the  Utility  Workers  Union  of  America,  AFL-CIO,  and  the
International  Federation of Professional and Technical Engineers,  AFL-CIO. The
agreements  include a 3.5% wage increase for 2006,  with wage increases for 2007
to be  negotiated  in the fall of 2006.  The Company  believes that it maintains
good relationships with the unions.  Employees at Washington Water, Hawaii Water
and New Mexico Water do not belong to Unions.

     The Company operates primarily in one business segment, providing water and
related utility services.

Note 2. 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.

     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,  net of the allowance for doubtful  accounts was $272 and
$287 at December  31, 2005 and 2004,  respectively.  The activity in the reserve
account is as follows:

                                                           2005         2004
                                                           ----         ----

                                                           ----        ------
Ending Balance                                            $ 272        $  287
                                                           ====        ======
     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.

     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
"Offsettable  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.


Notes to Consolidated Financial Statements

     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 $900 in 2005, $824 in 2004, and $1,995 in 2003.

     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  life.  Included  in
intangible  assets is $6,515 paid to the City of  Hawthorne in 1996 to lease the
city's 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:

                                                   2005            2004

                                               ==========      ==========

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

                                                                   Useful
                                                                    Lives
                                                                    -----

Equipment                                                   5 to 50 years
Transmission and distribution plant                        40 to 65 years
Office buildings and other structures                            50 years

     The provision for  depreciation  expressed as a percentage of the aggregate
depreciable asset balances was 2.7% in 2005, 2.6% in 2004, and 2.5% in 2003. 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 original maturities
of three  months or less.  As of December  31, 2005 and 2004,  cash  equivalents
included  investments  in money market funds in the amount of $4,003 and $6,133,
respectively,  and investment in high-quality  commercial paper in the amount of
zero and $4,997, 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.  All restricted cash
is  classified  in other  prepaid  expenses.  At  December  31,  2005 and  2004,
restricted cash was $1,200 and $1,337, 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 federal income tax depreciation on utility plant
that  was  placed  in  service   before  the  regulatory   Commissions   adopted
normalization  for  rate-making  purposes.  Previously,  the tax  benefit of tax
depreciation  was passed onto  customers  (flow-through).  For state  income tax
purposes,  the  Commission  continues to use the  flow-through  method.  As such
timing  differences  reverse,  the Company will be able to include the impact of
such differences in customer rates.  These federal tax differences will continue
to 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.  Asset retirement  obligations are recorded net of depreciation,
which has been  recorded and  recognized  through the  regulatory  process.  The
liabilities  relate to asset  retirement  obligations,  postretirement  benefits
other than pensions,  and accrued benefits for vacation,  self-insured  workers'
compensation, and directors' retirement benefits.



     Regulatory  liabilities  represent  future  benefits to ratepayers  for tax
deductions  that will be  allowed in the  future.  Regulatory  liabilities  also
reflect timing  differences  provided at higher than the current tax rate, which
will flow through to future ratepayers.

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

                                                           2005           2004

     Long-Lived  Assets

     The  Company  regularly  reviews  its  long-lived  assets  for  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 the asset. If assets are considered to be impaired,  the impairment
to be  recognized  is measured as the amount by which the carrying  value of the
asset  exceeds  its fair  value.  There  have  been no asset  impairments  as of
December 31, 2005 and 2004.

     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 the  unamortized  original issue discount and expense
are  amortized  over the life of new debt issued in  conjunction  with the early
redemption.  These  amounts  were  zero in 2005  and 2004  and  $3,154  in 2003.
Amortization  expense  included in interest expense was $661, $660, and $415 for
2005, 2004, and 2003, 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. Advances of $141,168 and
$130,558 at December 31, 2005 and 2004,  respectively,  are  refunded  primarily
over a 40-year period in equal annual amounts.  In addition,  other Advances for
Construction totaling $674 and $734 at December 31, 2005 and 2004, respectively,
are refundable based upon customer  connections.  Estimated  refunds of advances
for each succeeding year (2006 through 2010) are $5,077, $4,921, $4,856, $4,795,
$4,793, and $117,400 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 account.

     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.

     It is anticipated  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.  ITCs 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  subsequent  to 1991 were  subject to  California  income tax. In 1996,  the
federal tax


Notes to Consolidated Financial Statements


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 contributions of fire services from taxable income.

     Workers'  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.

     Stock-Based  Compensation

     The Company has a stockholder-approved Long-Term Incentive Plan under which
non-qualified  stock  options  are  outstanding.  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, 2005, 2004, or 2003.

     In 2005, the Company adopted a  stockholder-approved  Equity Incentive Plan
that allows certain stock-based compensation awards. There were no awards during
2005.  The Company  adopted SFAS No. 123 (revised 2004)  "Share-Based  Payment,"
effective  January  1,  2006,  and will be  recording  compensation  expense  in
accordance with that standard for any awards granted in the future.


     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 to stock-based employee compensation under the Long-Term Incentive Plan.

     Recent  Accounting  Pronouncements

     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 that would begin in
2006. Because the Company is regulated,  FSP No. 106-2 did not have an impact on
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 in 2004. In 2005, the Company elected to apply the entire subsidy to reduce
the cost of the retiree  health  care  expense.  The impact on the net  periodic
postretirement benefit costs for 2005 was to reduce the expense by $1,574.

     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  29 to  eliminate  the  exception  for
nonmonetary  exchanges  of  similar  productive  assets and  replaces  it with a
general  exception  for  exchanges  of  nonmonetary  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 quarter of 2006.  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 based upon the level of options
previously  granted and the level of awards  granted in January 2006. In January
2006,  Restrict  Stock  Awards were granted for 9,142 shares of common stock and
Stock Appreciation Rights Awards were granted for 37,500 shares of common stock.

     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 provides  guidance on the application of SFAS No. 109 to the provision
within the American Jobs Creation Act of 2004 (Act) that provides a


Notes to Consolidated Financial Statements


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  did not have a material  impact on the
Company's financial position, results of operations, or cash flows.

     In March 2005, the FASB issued Interpretation No. 46R-5, "Implicit Variable
Interests  under FASB  Interpretation  No. 46 (revised  December  2003),"  which
amends Interpretation No. 46, "Consolidation of Variable Interest Entities." The
revision  relates  to issues  commonly  arising in  leasing  arrangements  among
related parties and other types of arrangements  involving related and unrelated
parties.  The original guidance under  Interpretation  No. 46 in January 2003 is
still  applicable.  Interpretation  Nos.  46  and  46R-5  provide  guidance  for
determining when a primary  beneficiary  should  consolidate a variable interest
entity or equivalent  structure  that  functions to support the  activities of a
primary  beneficiary.  Interpretation  No.  46R-5  is  effective  for the  first
reporting period  beginning after March 3, 2005. The adoption of  Interpretation
No.  46R-5  did  not  impact  the  Company's  financial  position,   results  of
operations, or cash flows.

     In March  2005,  the FASB issued  Interpretation  No. 47,  "Accounting  for
Conditional  Asset Retirement  Obligations - an Interpretation of FASB Statement
No.  143."  Interpretation  No. 47 provides  guidelines  as to when a company is
required to record a conditional  asset retirement  obligation.  In general,  an
entity is required to recognize a liability  for the fair value of a conditional
asset retirement obligation if the fair value of the liability can be reasonably
estimated.  The fair value of a liability for the conditional  asset  retirement
obligation  should be  recognized  when incurred - generally  upon  acquisition,
construction, or development and (or) through the normal operation of the asset.
The  Interpretation  is  effective  no later than the end of fiscal years ending
after December 15, 2005 (December 31, 2005, for calendar-year enterprises).  The
adoption of this  Interpretation did not have a material impact on the Company's
financial position,  results of operations,  or cash flows. The Company has been
allowed  to  collect   retirement   obligation  costs  from  ratepayers  through
depreciation  expense.  As of  December  31,  2005,  the Company  estimates  its
retirement  obligation  costs to be $4,480,  of which $2,942 has been  collected
from ratepayers. The balance is recorded as a regulatory asset.

     In May 2005,  the FASB issued  Statement No. 154,  "Accounting  Changes and
Error  Corrections - a Replacement  of APB Opinion No. 20 and FASB Statement No.
3."  Statement  No. 154 replaces APB Opinion No. 20,  "Accounting  Changes," and
FASB  Statement  No. 3,  "Reporting  Accounting  Changes  in  Interim  Financial
Statements,"  and changes the  requirements for and the reporting of a change of
an accounting principle.  This Statement requires  retrospective  application to
prior periods' financial statements of changes in accounting  principle,  unless
it is  impracticable  to  determine  either the  period-specific  effects or the
cumulative effect of the change. The Statement is effective for all fiscal years
beginning after December 15, 2005. The adoption of this Statement did not have a
material impact on the Company's financial position,  results of operations,  or
cash flows.

Note 3. Other Income and Expenses

     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. 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 for the design and installation of water mains and
other water  infrastructure  for others outside the Company's  regulated service
areas.

Note 4. Acquisitions

     In 2005, after receiving  regulatory approval,  the Company's  subsidiaries
acquired three water systems for a combined  purchase  price of $807,  including
liabilities assumed of $336, which was the approximate value of the rate base in
aggregate of the assets acquired.

     In 2004, after receiving  regulatory  approval,  the Company's wholly owned
subsidiary,   New  Mexico  Water,  acquired  the  stock  of  National  Utilities
Corporation. The purchase was for $900, which was the approximate amount of rate
base of the  assets  acquired  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,  which was the approximate amount of
the rate base of assets acquired.

     Condensed  balance  sheets and pro forma  results of  operations  for these
acquisitions  have not been presented  since the impact of the purchases was not
material.   Minimal  or  no  goodwill  was  recorded  in  connection   with  the
acquisitions.

Note 6. Preferred Stock

     As of December 31, 2005 and 2004,  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.



Notes to Consolidated Financial Statements

Note 7. Common Stockholders' Equity

     The  Company is  authorized  to issue 25 million  shares of $0.01 par value
common stock. As of December 31, 2005 and 2004, 18,389,996 shares and 18,367,246
shares, respectively, of common stock were issued and outstanding.

     Dividend  Reinvestment and Stock Repurchase Plan

     The Company 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  protect
stockholders  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 person's  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 holder's  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.

Note 8. Short-Term Borrowings

     At  December  31,  2005,  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  $10  million  and $5  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,  2005,  there  were no
borrowings  on the Company or Cal Water line,  and one letter of credit for $0.5
million is outstanding under the 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
substantially  all of Cal Water's  utility  plant.  The senior notes are held 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 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.  Aggregate maturities and sinking fund requirements for
each of the  succeeding  five years  (2006  through  2010) are  $1,133,  $1,115,
$1,095, $1,026, and $965, and $269,941 thereafter.

     Included in Other in the above table is the recognition of the flow-through
accounting for federal  depreciation  expense on assets  acquired prior to 1982.
For assets  acquired prior to 1982, the benefit of excess tax  depreciation  was
previously  passed through to the  ratepayers.  The tax benefit is now reversing
and a higher tax expense is being recognized and is included in customer rates.



     In October  2004,  the American  Jobs Creation Act of 2004 (Act) was signed
into law and provides a new federal  income tax deduction  from  qualified  U.S.
production  activities,  which is being phased in from 2005 through 2010.  Under
the Act,  qualified  production  activities include production of potable water,
but exclude the  transmission and distribution of the potable water. In December
2004,  the FASB issued  FASB Staff  Position  No.  109-1 and  proposed  that the
deduction  should be accounted for as a "special  deduction" in accordance  with
SFAS No.  109.  As such,  the special  deduction  had no effect on deferred  tax
assets and liabilities existing at the enactment date. Rather, the impact of the
deduction is being reported in the year in which the deduction is claimed on the
Company's tax return.  During 2005, the Company  completed its evaluation of the
provisions  of the Act and  included a  deduction  in the  provision  for income
taxes. The impact was to lower the income tax provision by $175 in 2005.

     A valuation allowance was not required at December 31, 2005 and 2004. 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.



Notes to Consolidated Financial Statements

Note 12. Employee Benefit Plans

     Pension   Plans

     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 costs 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 plans will be $7.4 million in 2006.  Plan assets in
the  defined  benefit  pension  plan as of  December  31,  2005  and  2004  (the
measurement dates for the plan) were as follows:


Asset Category                     Target        2005          2004
- --------------                     ------        ----          ----
Bond funds                      35% to 45%       36.4%         39.4%
Equity accounts                 55% to 65%       63.6%         60.6%


     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  payment  obligations  are  generally  funded by the purchase of an
annuity from a life  insurance  company.  In 2005, the Plan  annuitized  pension
benefits that would otherwise be paid to certain retirees in the future. Benefit
payments under the  supplemental  executive  retirement plan are paid currently.
Excluding costs to annuitize future retirement benefits, benefits expected to be
paid in each year from 2006 through 2010 are $2,610, $3,266, $4,412, $5,617, and
$5,683,  respectively.  The  aggregate  benefit  expected to be paid in the five
years 2011 through 2015 is $39,142. The expected benefit payments are based upon
the same  assumptions  used to  measure  the  Company's  benefit  obligation  at
December 31, 2005, and include estimated future employee service.

     The  accumulated  benefit  obligations  of the pension plan are $71,463 and
$65,938  as of  December  31,  2005 and 2004,  respectively.  The fair  value of
pension  plan assets was  $70,225 and $75,064 as of December  31, 2005 and 2004,
respectively.  The unfunded  supplemental  executive retirement plan accumulated
benefit  obligations  were $8,608 and $7,234 as of  December  31, 2005 and 2004,
respectively.

     The data in the  following  tables  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 pre-tax  compensation.  The
Company  matches 50 cents for each dollar  contributed  by the  employee up to a
maximum Company match of 4.0%. Company  contributions  were $1,498,  $1,443, and
$1,433, for the years 2005, 2004, and 2003, respectively.

     Other  Postretirement

     Plan 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 other than pension
during the  employees'  years of active  service.  The  Company  has  recorded a
regulatory  asset in prior years for the difference  between the  Company-funded
amount and the net periodic  benefit cost. The Company  intends to file with the
Commission an Advice Letter to recover the regulatory  asset in future  customer
rates, as customer rates have only included the lower Company-funded amount.


     The  following  table  reconciles  the funded  status of the plans with the
accrued pension  liability and the net  postretirement  benefit  liability as of
December 31, 2005 and 2004:

Notes to Consolidated Financial Statements


     Below  are the  actuarial  assumptions  used  in  determining  the  benefit
obligation for the benefit plans:


                                                                Pension Benefits   Other Benefits

     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
7% and 8.7%, respectively.

     Net periodic benefit costs for the pension and other  postretirement  plans
for the years ending  December 31, 2005,  2004,  and 2003 included the following
components:


                                                           Pension Plan                             Other Benefits

     Postretirement  benefit  expense  recorded  in 2005,  2004,  and 2003,  was
$1,572,  $1,420,  and $1,160,  respectively.  The remaining net periodic benefit
cost as of December  31,  2005,  of $9,791 is expected to be  recovered  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 2005 measurement  purposes,  the Company assumed an 8.5% annual rate of
increase in the per capita cost of covered benefits, with the rate decreasing 1%
per year for the next four  years to a  long-term  annual  rate of 4.5% per year
after four years.  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

Effect on total service and interest costs                     $   422            $   (331)
Effect on accumulated postretirement benefit obligation        $ 3,693            $ (2,949)





Note 13. Stock-Based Compensation Plans

     The Company has two  stockholder-approved  stock-based  compensation plans.
Under the Long-Term  Incentive Plan that allowed granting of non-qualified stock
options, some of which are currently outstanding, there will be no future grants
made.  Options were granted  under the Long-Term  Incentive  Plan at an exercise
price that was not less than the per share common stock market price on the date
of grant.  At December 31, 2005,  86,500 options were  exercisable at a weighted
average  price of $24.93.  The options  vest at a 25% rate on their  anniversary
date over their first four years and are exercisable  over a 10-year period.  No
options were granted in 2005, 2004, or 2003.

     The following  table  summarizes  the activity of the  Long-Term  Incentive
Plan:

     In   2005,    the   Long-Term    Incentive   Plan   was   replaced   by   a
stockholder-approved  Equity  Incentive Plan, which allows granting of incentive
and non-qualified  stock options,  stock appreciation  rights,  restricted stock
awards,  and other stock  awards.  Under the Equity  Incentive  Plan, a total of
1,000,000  common shares have been authorized for future grants.  As of December
31,  2005,  there were no grants  under the Plan.  The Company will be reporting
compensation  expense  related to any grants under this plan in accordance  with
SFAS No. 123 (revised 2004), as discussed in Note 2.

Note 14. 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,  and accounts payables,  the carrying amount
approximates  the  fair  value  because  of  the  short-term   maturity  of  the
instruments. The fair value of the Company's long-term debt is estimated at $289
million and $301 million as of December 31, 2005, and 2004, 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
$274 million and $276  million as of December  31, 2005 and 2004,  respectively.
The fair value of  Advances  for  Construction  contracts  is  estimated  at $57

Note 15. Commitments and Contingencies

     Commitments

     The Company leases office facilities and two water systems from cities, and
has  long-term  commitments  to  purchase  water  from  water  wholesalers.  The
commitments are noted in the table below.


                             Office Leases    System Leases    Water Contracts
                             -------------    -------------    ---------------

2006                                 $ 662            $ 961           $ 12,731

Thereafter                              65            6,427            335,842

     The Company  leases office  facilities in many of its operating  districts.
The total paid and charged to operations for such leases was $682 in 2005,  $632
in 2004, and $577 in 2003.

     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 2005,  2004, and 2003 were $116, $116, and $111,
respectively.  In July 2003, the Company  negotiated a 15-year lease of the City
of Commerce water system. At this time, the lease has not been formally executed
by the parties. The lease includes an annual lease payment of $845 per year plus
a cost-savings sharing arrangement.

     The Company has a long-term  contract with Santa Clara Water  District that
requires the Company to purchase minimum annual water quantities.  Purchases are
priced at the District's then-current wholesale water rate. The Company operates
to purchase sufficient water to equal or exceed the minimum quantities under the
contract.  The total paid under the contract was $4,763 in 2005, $4,610 in 2004,
and $4,452 in 2003.

     The Company  also has a water  supply  contract  with  Stockton  East Water
District  (SEWD) that 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
$4,300 in 2005,  $4,392 in 2004, and $3,779 in 2003.  Pricing under the contract
varies annually. Estimated annual contractual obligations in the table above are
based on the same payment  levels as 2005.  Future  increased  costs by SEWD are
expected to be offset by a decline in the allocation of costs to the Company, as
other customers of SEWD are expected to receive a larger  allocation  based upon
growth of their service areas.

     On September  21,  2005,  the Company  entered into an agreement  with Kern
County  Water  Agency  (Agency)  to  obtain  treated  water  for  the  Company's
operations.  The term of the  agreement  is to  January  1,  2035,  or until the
repayment of the Agency's bonds (described hereafter) occurs. Under the terms of
the agreement,  the Company is obligated to purchase 20,500 acre-feet of treated
water per year.  The Company is obligated to pay the Capital  Facilities  Charge
and the Treated  Water Charge  regardless of whether it can use the water in its
operation,  and is obligated for these charges even if the Agency cannot produce
an adequate amount to supply the 20,500  acre-feet in the year.  (This agreement
supersedes  a prior  agreement  with Kern County  Water Agency for the supply of
11,500 acre-feet of water per year. The total paid under the prior agreement was
$3,288 in 2005, $3,308 in 2004, and $2,691 in 2003.)

     Three other parties, including the City of Bakersfield,  are also obligated
to purchase a total of 32,500 acre-feet per year under separate  agreements with
the Agency.  Furthermore,  the Agency has the right to proportionally reduce the
water supply provided to all of the  participants if it cannot produce  adequate
supplies.  The  participation of all parties in the transaction for expansion of
the Agency's facilities, including the Water Purification Plant, purchase of the
water,  and payment of interest  and  principal on the bonds being issued by the
Agency to finance the transaction,  is required as a condition to the obligation
of the Agency to proceed with  expansion of the Agency's  facilities.  If any of
the other  parties does not use its  allocation,  that party is obligated to pay
its contracted amount.


     The Agency is  planning to issue bonds to fund the project and will use the
payments  of the  Capital  Facilities  Charges  by the  Company  and  the  other
contracted  parties to meet the Agency's  obligations  to pay interest and repay
principal on the bonds. If any of the parties were to default on making payments
of the Capital  Facilities  Charge,  then the other parties are obligated to pay
for the  defaulting  party's  share on a pro-rata  basis.  If there is a payment
default by a party and the  remaining  parties have to make  payments,  they are
also entitled to a pro-rata share of the defaulting party's water allocation.

     The  Company  expects  to use all its  contracted  amount  of  water in its
operations  every year. In addition,  if the Company were to pay for and receive
additional amounts of water due to a default of another participating party; the
Company  believes it could use this additional  water in its operations  without
incurring substantial incremental cost increases. If additional treated water is
available, all parties have an option to purchase this additional treated water,
subject to the Agency's right to allocate the water among the parties.

     The  total   obligation  of  all  parties,   excluding   the  Company,   is
approximately $108 million to the Agency.  Based on the  creditworthiness of the
other participants,  which are government entities,  it is believed to be highly
unlikely  that the  Company  would be  required  to assume  any  other  parties'
obligations under the contract due to their default.  In the event of default by
a party,  the Company  would receive  entitlement  to the  additional  water for
assuming any obligation.

     Once the project is  complete,  the Company is  obligated  to pay a Capital
Facilities  Charge and a Treated Water Charge that  together  total $4.7 million
annually,  which equates to $231 per acre-foot.  Annual payments of $2.0 million
for the Capital  Facilities  Charge will begin when the Agency  issues  bonds to
fund the project.  Some of the Treated  Water Charge of $2.8 million is expected
to begin July 1, 2007, when a portion of the planned  capacity is expected to be
available. The expanded water treatment plant is expected to be at full capacity
by July 1, 2008, and at that time, the full annual payments of $4,739,000  would
be made and continue  through the term of the  agreement.  Once treated water is
being  delivered,  the  Company  will also be  obligated  for its portion of the
operating  costs;  that portion is currently  estimated to be $69 per acre-foot.
The actual amount will vary due to variations from  reimbursable  operating cost
estimates,  inflation,  and other changes in the cost  structure.  The Company's
overall  estimated cost of $300 per acre-foot is less than the estimated cost of
procuring  untreated  water  (assuming  water rights could be obtained) and then
providing treatment.

     Contingencies

     In 1995, the State of California's  Department of Toxic Substances  Control
(DTSC) named Cal Water as a potential  responsible  party for cleanup of a toxic
contamination  plume in the Chico  groundwater.  The toxic spill  occurred  when
cleaning  solvents,  which were discharged into the city's sewer system by local
dry cleaners,  leaked into the underground water supply.  The DTSC contends that
Cal Water's  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.  The parties have  undertaken
settlement  negotiations.  In response to Cal Water's  request for its insurance
carrier  to  participate  in  settlement  negotiations,  the  insurance  carrier
threatened to exercise its reservation of rights letter to seek reimbursement of
past defense  costs.  Past defense costs  approximate  $0.6  million.  Cal Water
believes  that the carrier  clearly has a duty to defend and is not  entitled to
any defense cost reimbursement.  Furthermore,  Cal Water believes that insurance
coverage exists for this claim.  If Cal Water's claim is ultimately  found to be
excludable under its policies, Cal Water believes any damages will be covered by
the ratepayer as pump-and-treat  is the most economical  approach to the cleanup
effort.  Cal Water believes that there will not be a material  adverse effect to
its financial position or results of operations.

     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 California Public Utilities Commission (CPUC)
issued  decision  D.03-09-021  in Cal Water's 2001 General Rate Case 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  Water's
application. On January 11, 2005, the Office of Ratepayer Advocates (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 be used to
benefit ratepayers.


Notes to Consolidated Financial Statements


     During the period under review,  Cal Water's  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.

     On December 1, 2005, the CPUC issued its decision  D.05-12-002  (Decision).
The Decision found that Cal Water  appropriately  reclassified all properties as
non-utility  property  prior to being sold.  The criteria Cal Water  followed to
reclassify its properties was reasonable and consistent with the requirements of
the CPUC. Since the properties were properly reclassified, CPUC approval was not
required  prior  to the sale  and no  penalty  is  warranted.  Furthermore,  the
Decision  found  that Cal Water  should be  allowed  to include in rate base the
remaining $1,182,462 of the Chico customer center costs not yet in rate base and
to earn a return on the additional rate base, an increased  revenue  requirement
of approximately $171,000.

     However,  the  Decision  did not  approve the amount of sale  proceeds  (or
gains) that qualify for reinvestment under the  Infrastructure  Act, although it
concluded  that all property sales should qualify and should be accounted for in
accordance with the Act. The Decision defers the issues  regarding  treatment of
sale  proceeds and  allocation of gains on sale to its  R.04-09-003  proceeding,
where the CPUC intends to set  guidelines  and a specific  rule on allocation of
the gain on utility asset sales between shareholders and ratepayers. On November
5,  2005,  the  Commission  mailed its  proposed  decision  (Proposed  Decision)
regarding  the  allocation  of  proceeds  from the sale of utility  assets.  The
Proposed  Decision  states that the Commission has limited  discretion in how it
allocates gains on sale of real property, provided that water companies reinvest
the proceeds in new water  infrastructure.  As such,  the Company is entitled to
earn a full authorized return on the proceeds reinvested in utility plant.

     Based on the Decision and the Proposed Decision,  Cal Water has not accrued
a liability in its  financial  statements.  Cal Water has no knowledge  when the
CPUC will issue its decision in the matter of R.04-09-003. If the CPUC finds any
portion of the property sales should be allocated to the ratepayers, Cal Water's
rate base could be reduced,  which would lower future revenues,  net income, and
cash flows.

     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.

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
Management's  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, 2005, 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 management's  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 management's  assessment,  testing
and evaluating the design and operating  effectiveness of internal control,  and
performing   such  other   procedures   as  we   considered   necessary  in  the
circumstances.  We believe that our audit  provides a  reasonable  basis for our
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, management's assessment that California Water Service Group
and subsidiaries  maintained effective internal control over financial reporting
as of December 31, 2005, 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, 2005, based on the criteria established in Internal
Control - Integrated Framework issued by 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,
2005 and  2004,  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, 2005,  and our report dated
March 9, 2006, 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, 2005 and 2004, 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, 2005. 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, 2005 and 2004, and the
results  of their  operations  and their cash flows for each of the years in the
three-year  period ended  December 31, 2005, 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,  2005,  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 March 9,
2006,  expressed an unqualified  opinion on management's  assessment of, and the
effective operation of, internal control over financial reporting.

Controls and Procedures


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 principal  executive officer and
principal financial officer, of the effectiveness of the design and operation of
the  Company's  disclosure  controls  and  procedures  as of December  31, 2005,
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 Acting 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  Acting  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,  2005,  that has  materially
affected,  or is reasonably likely to materially  affect, the Company's internal

internal  control over  financial  reporting  (as defined in Rule  13a-15(f) and

has concluded that, as of December 31, 2005, the Company's internal control over
