                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Plan Administrator of the
  Southern California Water Company
  Investment Incentive Program:


We have audited the accompanying statements of net assets available for plan
benefits of the SOUTHERN CALIFORNIA WATER COMPANY INVESTMENT INCENTIVE PROGRAM
(the "Plan") as of December 31, 1998 and 1997, and the related statement of
changes in net assets available for plan benefits for the year ended December
31, 1998. These financial statements and the schedules referred to below are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements and schedules based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. 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 financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits of the Plan as
of December 31, 1998 and 1997, and the changes in net assets available for plan
benefits for the year ended December 31, 1998, in conformity with generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. Schedules I, II and III listed in the
accompanying index are presented for the purpose of additional analysis and are
not a required part of the basic financial statements but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The fund information in the statements of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits
is presented for purposes of additional analysis rather than to present the net
assets available for plan benefits and changes in net assets available for plan
benefits of each fund. The supplemental schedules and fund information have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

                        SOUTHERN CALIFORNIA WATER COMPANY

                          INVESTMENT INCENTIVE PROGRAM

                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1998 AND 1997



1.       Plan Description

         The following description of the Southern California Water Company
         Investment Incentive Program (the "Plan") provides only general
         information. Participants should refer to the Plan document for a more
         complete description of the Plan's provisions.

         General

         The Plan is a defined contribution plan established by the Southern
         California Water Company (the "Company") under the provisions of
         Section 401(a) of the Internal Revenue Code (the "IRC"), which includes
         a qualified cash or deferred arrangement as described in Section 401(k)
         of the IRC, for the benefit of eligible employees of the Company. The
         Plan is subject to the provisions of the Employee Retirement Income
         Security Act of 1974 ("ERISA"), as amended.

         Prior to inception of the Plan, the Company maintained the
         Payroll-Based Tax Credit Employee Stock Ownership Plan (the "PAYSOP")
         for the benefit of participating employees and their beneficiaries.
         Under the PAYSOP, the Company contributed amounts equal to a tax credit
         claimed by the Company on its federal income tax return. This credit
         was calculated as a percentage of qualifying payroll. The Tax Reform
         Act of 1986 eliminated this credit for tax years after 1986. As a
         result, the Company terminated the PAYSOP and transferred the net
         assets into the Plan effective January 1, 1988. The trustee maintains a
         separate account for the net assets which were transferred from the
         PAYSOP (See Note 2).

         Plan Administration

         Under a trust agreement dated May 4, 1988, Wells Fargo Bank, N.A.
         (formerly First Interstate Bank) was appointed trustee for the Plan
         (the "Trustee"). The Plan is administered by the Investment Incentive
         Program Committee (the "Plan Administrator"), which is appointed by the
         Company's Board of Directors.

         Eligibility

         Effective  January 1, 1996 any employee  who has  completed a period of
         service of 30 consecutive days is eligible to participate in the Plan.

         Contributions

         Effective January, 1, 1996, eligible employees can contribute an amount
         between one percent and fifteen percent of compensation, as defined in
         the Plan document. In addition, the Company provides matching
         contributions of 100 percent of the first three percent and 50 percent
         of the next three percent contributed by a participant. Under the terms
         of the Plan, employer matching contributions are invested in the
         American States Water Company Stock Fund, formerly known as the
         Southern California Water Company Stock Fund.





                                       7

         Vesting

         Participants are fully vested in all employer matching contributions
         made to their account and the earnings thereon. Accordingly, there are
         no forfeited non-vesting accounts as of December 31, 1998 and 1997.

         Distribution of Benefits

         Participants' benefits under the Plan become distributable upon
         severance from service, as defined in the Plan document. Participants
         electing to have their distribution deferred will receive benefits
         equal to the amounts credited to their accounts as of the end of the
         next calendar quarter. The value of benefits distributable to
         participants not electing deferral is based upon amounts credited to
         the participants' accounts under the Plan as of the end of the next
         preceding calendar quarter, except as described below.

         A participant shall be entitled to request an in-service withdrawal of
         the lesser of the balance of his/her deferral account or total
         unwithdrawn deferral contributions after the participant has attained
         age 59-1/2. Such a distribution shall be permitted only once every two
         years while the participant remains as an employee. In addition,
         subject to the approval of the Plan's Administrator, withdrawals from
         the participant's deferral account may be permitted before age 59-1/2
         to meet a financial hardship.

         Participant Accounts

         Individual accounts are maintained for each of the Plan's participants
         to reflect the participants' contributions and related employer
         matching contributions, as well as the participants' share of the
         Plan's income and any related administrative expenses. Allocations are
         based on the proportion that each participant's account balance has to
         the total of all participants' account balances.

2.       Investment Options

         Participants may direct their contributions and any related earnings
         into various investment options. Participants may change their
         investment elections on a daily basis, in full percent increments.
         Participants may not direct the investment of employer matching
         contributions. Employer contributions and the net assets of the former
         PAYSOP, and the respective earnings thereon are both in the form of
         Company stock and have been combined for financial statement purposes
         under the heading "Non-Participant Directed".

         A description of each investment option is provided below:

                  American States Water Company Stock Fund (Formerly known as
                  Southern California Water Company Stock Fund)

                  The objective of this fund is to invest in American States
                  Water Company Water Company common stock. From time to time,
                  the Plan may maintain a portion of the fund's assets in cash
                  or forms of short-term investments, provided that such
                  accounts remain primarily invested in American States Water
                  Company common stock.

                  income without significant principal volatility. The fund
                  primarily invests in a variety of high quality fixed-income
                  securities.

                  Wells Fargo S&P 500 Stock Fund

                  The objective of this fund is to provide returns comparable to
                  the returns of the S&P 500 Stock Index by investing in the
                  same stocks and in substantially the same percentages as the

                  instruments.

                  Westcore Intermediate Term Bond Fund

                  The objective of this fund is to provide current income with
                  little volatility of principal by investing in high quality
                  corporate and government bonds with maturities between three
                  and six years.

         Participant Loans

         Effective June 5, 1996, a participant may borrow, subject to certain
         restrictions and tax law requirements, the lesser of $50,000 or 50
         percent of his or her account balance, with a minimum loan amount of
         $1,000. Loan transactions are treated as a transfer to (from) the
         investment fund from (to) Participant Loans. Principal and interest are
         repayable ratably through payroll deductions over 36 months for loans
         less than $5,000 and within 59 months for all other loans. The loans
         bear interest at the Prime Rate plus one percent. The interest rates
         for the 1998 Plan year range from 8.75 to 9.50 percent. A loan is
         considered to be in default if any scheduled payment is more than 30
         days late. Defaulted loans are treated as a taxable distribution from
         the Plan and loans in default at December 31, 1998, which were
         uncollectable, were treated as a taxable distribution in 1999. Prior to
         June 5, 1996, participants were not allowed to borrow from the Plan.

3.       Summary of Significant Accounting Policies

         Basis of Accounting

         The accompanying financial statements are prepared on the accrual basis
         of accounting. The preparation of the financial statements in
         conformity with generally accepted accounting principles requires the
         Plan's management to use estimates and assumptions that affect the





                                       9
   10

         reported amounts of assets, liabilities and changes therein, and
         disclosure of contingent assets and liabilities. Actual results could
         differ from those estimates.

         Income Recognition

         Purchases and sales of securities are recorded on a settlement-date
         basis. Interest income is recorded as earned on the accrual basis.
         Dividend income is recorded on the ex-dividend date.

         Investment Valuation

         Investments are stated at fair value. Investments in collective funds,
         registered investment companies, and Company stock are valued at quoted
         market prices, which represent the net asset value of shares held by
         the Plan at year end. Participant loans are valued at cost, which
         approximate fair value.

         Net Appreciation in Fair Value of Investments

         Net realized and unrealized appreciation (depreciation) is recorded in
         the accompanying Statement of Changes in Net Assets available for Plan
         Benefits, as net appreciation (depreciation) in fair value of
         investments.

         Distributions to Participants

         Distributions to participants are recorded when paid.

         Administrative Expenses

         Administrative fees for accountants, legal counsel and other
         specialists and any other costs of administering the Plan, unless paid
         directly by the Company, will be paid by the Plan and will be charged
         against participants' accounts. Certain administrative expenses
         directly relating to participant accounts are specifically allocated
         and deducted from the participants' accounts. During 1998 and 1997,
         administrative expenses borne by the Plan and by the Company were
         insignificant.

         Administrative expenses incurred related to the net assets of the
         former PAYSOP account, that are paid out of the Plan, are limited to
         the lesser of (i) the sum of 10 percent of the first $100,000 and 5
         percent of any amount in excess of $100,000 of the income from
         dividends paid to the Plan with respect to Company stock allocated to
         the PAYSOP account during the plan year, or (ii) $100,000.

4.       Related Party Transactions

         The Wells Fargo Stable Asset Fund and the Wells Fargo S&P 500 Stock
         Fund (collectively the "Wells Funds") are managed by Wells Fargo Bank,
         N.A. As such, transactions in the Wells Funds qualify as exempt
         party-in-interest transactions.

5.       Tax Status

         The Internal Revenue Service issued a determination letter dated
         November 6, 1996 stating that the Plan and related trust are designed
         in accordance with applicable IRC requirements as of that date. The
         Plan Administrator and the Plan's tax counsel believe that the Plan was
         qualified and was tax-exempt for the years ended December 31, 1998 and
         1997.





                                       10
   11

         Plan Termination

         Although it has not expressed any intent to do so, the Company has the
         right under the Plan to discontinue its contributions at any time and
         to amend or terminate the Plan subject to the provisions of ERISA.

6.       Reconciliation  of Financial Statements to Form 5500

         The Plan financial statements are prepared on the accrual basis of
         accounting, however, the Form 5500 is prepared on the cash basis. The
         following is a reconciliation of net assets available for plan benefits
         per the financial statements to the Form 5500:
