PART I

Item 1. Financial Statements

General

The basic financial statements included herein have been prepared by Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission.

Certain information and footnote disclosures normally included in financial statements, prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments consisting of normal recurring items and estimates necessary for a fair statement of results for the interim period have been made.

It is suggested that these financial statements be read in conjunction with the financial statements and notes thereto in the latest Annual Report on Form 10-K of American States Water Company and its wholly-owned subsidiary, Golden State Water Company.

Filing Format

This quarterly report on Form 10-Q is a combined report being filed by two separate Registrants: American States Water Company (hereinafter “AWR”) and Golden State Water Company (hereinafter “GSWC”). For more information, please see Note 1 to the Notes to Consolidated Financial Statements and the heading entitled General in Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations. References in this report to “Registrant” are to AWR and GSWC collectively, unless otherwise specified. GSWC makes no representations as to the information contained in this report relating to AWR and its subsidiaries, other than GSWC.

Forward-Looking Information

Certain matters discussed in this report (including the documents incorporated herein by reference) are forward-looking statements intended to qualify for the “safe harbor” from liability established by the Private Securities Litigation Reform Act of 1995. These forward-looking statements can generally be identified as such because the context of the statement will include words such as Registrant “believes,” “anticipates,” “expects” or words of similar import. Similarly, statements that describe Registrant’s future plans, objectives, estimates or goals are also forward-looking statements. Such statements address future events and conditions concerning capital expenditures, earnings, litigation, rates, water quality and other regulatory matters, adequacy of water supplies, the ability to recover supply costs from ratepayers, contract operations, liquidity and capital resources, and accounting matters. Actual results in each case could differ materially from those currently anticipated in such statements, by reason of factors such as changes in utility regulation, including ongoing local, state and federal activities; recovery of regulatory assets not yet included in rates; future economic conditions, including changes in customer demand and changes in water and energy supply costs; future climatic conditions; and legislative, legal proceedings, regulatory and other circumstances affecting anticipated revenues and costs.

AMERICAN STATES WATER COMPANY
AND
GOLDEN STATE WATER COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

Note 1 — Summary of Significant Accounting Policies:

General / Nature of Operations: American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”), Chaparral City Water Company (“CCWC”), and American States Utility Services, Inc. (“ASUS”) and its subsidiaries. More than 90% of AWR’s assets consist of the common stock of GSWC and its revenues and operations are primarily those of GSWC. GSWC is a public utility engaged principally in the purchase, production, distribution and sale of water in California serving over 254,000 water customers. GSWC also distributes electricity in several California mountain communities serving over 23,000 electric customers. The California Public Utilities Commission (“CPUC”) regulates GSWC’s water and electric business, including properties, rates, services, facilities and other matters. CCWC is a public utility regulated by the Arizona Corporation Commission (“ACC”) serving over 13,000 customers in the town of Fountain Hills, Arizona and a portion of the City of Scottsdale, Arizona. ASUS performs water related services and operations on a contract basis. There is no direct regulatory oversight by either the CPUC or the ACC of the operation or rates of the contracted services provided by ASUS and its wholly-owned subsidiaries or by AWR.

Basis of Presentation: The consolidated financial statements of AWR include the accounts of AWR and its subsidiaries, all of which are wholly owned. These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America. Inter-company transactions and balances have been eliminated in the AWR consolidated financial statements. The consolidated financial statements included herein have been prepared by Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America for annual financial statements have been condensed or omitted pursuant to such rules and regulations. The preparation of the consolidated financial statements 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 revenue and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments, consisting of normal, recurring items and estimates necessary for a fair statement of the results for the interim periods, have been made. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Form 10-K for the year ended December 31, 2006 filed with the SEC. Certain prior-period amounts were reclassified to conform to the March 31, 2007 financial statement presentation.

GSWC’s Related Party Transactions: GSWC and other subsidiaries provide and receive various services to and from their parent, AWR, and among themselves. In addition, AWR has an $85 million syndicated credit facility. AWR borrows under this facility and provides funds to its subsidiaries, including GSWC, in support of their operations. Amounts owed to AWR for borrowings under this facility represent the majority of GSWC’s inter-company payables on GSWC’s balance sheets as of March 31, 2007 and December 31, 2006. The interest rate charged to GSWC is sufficient to cover AWR’s interest cost under the credit facility. GSWC also allocates certain corporate office administrative and general costs to its affiliates using agreed upon allocation factors.

New Accounting Pronouncements: In March 2006, the Financial Accounting Standards Board (“FASB”) Emerging Issues Task Force (“EITF”) issued EITF No. 06-03, “How Sales Taxes Collected From Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement.” A consensus was reached that entities may adopt a policy of presenting sales taxes in the income statement on either a gross or net basis, based on their accounting policy, which should be disclosed. If such taxes are significant, and are presented on a gross basis, an entity should also disclose the amounts of those taxes. Effective January 1, 2007, Registrant adopted the guidance of EITF No. 06-03. GSWC bills certain sales and use taxes levied by state or local governments to its customers. Included in these sales and use taxes are franchise fees, which GSWC pays to various municipalities (based on contracts with these municipalities) in order to operate within the limits of the municipality. GSWC bills these franchise fees to its customers based on a CPUC-authorized rate. These franchise fees, which are required to be paid regardless of GSWC’s ability to collect from the customer, are accounted for on a gross basis. GSWC’s franchise fees billed to customers and recorded as operating revenue were approximately $733,000 and $578,000 for the three months ended March 31, 2007 and 2006, respectively. When GSWC acts as an agent, and the tax is not required to be remitted if it is not collected from the customer, the taxes are accounted for on a net basis.

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109” (“FIN 48”). Effective January 1, 2007, Registrant adopted the provisions of FIN 48. See Note 5 for further details and impact on the adoption of FIN 48.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements”, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. This statement is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Early adoption is encouraged, provided that Registrant has not yet issued financial statements for that fiscal year, including any financial statements for an interim period within that fiscal year. Registrant will implement the new standard effective January 1, 2008. Registrant is currently evaluating the impact SFAS No. 157 may have on its financial statements and disclosures.

Note 2 — Regulatory Matters:

In accordance with accounting principles for rate-regulated enterprises, Registrant records regulatory assets, which represent probable future revenue associated with certain costs that will be recovered from customers through the ratemaking process, and regulatory liabilities, which represent probable future reductions in revenue associated with amounts that are to be credited to customers through the ratemaking process. At March 31, 2007, Registrant had $7.4 million of regulatory assets not accruing carrying costs. Of this amount, $6.7 million relates to deferred income tax representing accelerated tax benefits flowed-through to ratepayers, which will be included in rates concurrently with recognition of the associated future tax expense. In addition, there are other expenses that Registrant recovers in rates over a short period that do not provide for recovery of carrying costs. At March 31, 2007, $673,000 was recorded as other regulatory assets for such expenses to be recovered. Regulatory assets, less regulatory liabilities, included in the consolidated balance sheets are as follows:

(In thousands)	March 31, 2007			December 31, 2006
GSWC
Supply cost balancing accounts	$	18,741		$	17,321
Supply cost memorandum accounts net under/(over)-collections	6,752			7,429

CCWC
Asset retirement obligations	$	49		$	48
Other regulatory liabilities, net	(583		)	(565		)
Total AWR	$	84,934		$	84,457

Regulatory matters are discussed in detail in the consolidated financial statements and the notes thereto included in the Form 10-K for the year ended December 31, 2006 filed with the SEC. Discussion below focuses on significant matters and changes since December 31, 2006.

Supply Cost Balancing and Memorandum Accounts:

Electric Supply Cost Balancing Account — Electric power costs incurred by GSWC’s Bear Valley Electric division continue to be charged to its electric supply cost balancing account. The under-collection in the electric supply cost balancing account is $19.1 million at March 31, 2007. The balance in the electric supply balancing account is primarily impacted by: (i) a surcharge to decrease previously under-collected energy costs, (ii) changes in purchased energy costs, and (iii) changes in power system delivery costs.

The CPUC has authorized GSWC to collect a surcharge from its customers of 2.2¢ per kilowatt hour through August 2011, to enable GSWC to recover an under-collection of approximately $23.1 million at the end of 2001 which had been incurred during the energy crisis in late 2000 and 2001. GSWC sold 42,683,779 and 42,294,078 kilowatt hours of electricity to its Bear Valley Electric division customers for the three months ended March 31, 2007 and 2006, respectively. As a result, the supply cost balancing account was reduced by approximately $918,000 and $880,000 for the three months ended March 31, 2007 and 2006, respectively. Approximately $15.0 million of the under-collection incurred during the energy crisis in late 2000 and 2001 has been recovered through this surcharge. GSWC anticipates the surcharge, based on electricity sales, to be sufficient for it to recover the amount of the under-collected balance incurred during the energy crisis by August 2011. However, in 2011, if GSWC has not fully recovered the amount of this under collection, GSWC will seek recovery of any amounts not recovered through this surcharge.

The purchased energy costs that are recorded in the supply cost balancing account are subject to a price cap by terms of the 2001 settlement with the CPUC. The Bear Valley Electric division of GSWC is allowed to include up to a weighted average annual energy purchase cost of $77 per megawatt-hour (“MWh”) through August 2011 in its electric supply cost balancing account for purchased energy costs. To the extent that the actual weighted average annual cost for power purchased exceeds the $77 per MWh amount, GSWC will not be able to include these amounts in its balancing account and such amounts will be expensed. During the three months ended March 31, 2007 and 2006, the amounts expensed were $29,000 and $40,000, respectively, over the $77 per MWh cap.

Charges to GSWC by Southern California Edison (“Edison”), a subsidiary of Edison International, associated with the transportation of energy over Edison’s power system and the abandonment of a transmission line upgrade have increased under Edison’s tariff to levels that exceed the amounts authorized by the CPUC in Bear Valley Electric’s retail power rates to its customers. The incremental cost increase to GSWC from the tariff for the abandonment of a transmission line upgrade, which is not included in rates, is $38,137 per month. These increases have been included in the balancing account for subsequent recovery from customers. The incoming power system delivery costs are not subject to the $77 per MWh price cap referenced above. Other components, such as interest accrued on cumulative under-collected balance and power loss during transmission, also affect the balance of the electric supply cost balancing account.

In summary, for the three months ended March 31, 2007 and 2006, the under-collection decreased by approximately $783,000 and $219,000, respectively.

Water Supply Cost Memorandum/Balancing Accounts — All water utilities regulated by the CPUC were required to seek review of supply cost under- and over- collections by filing an advice letter annually and to reduce the utility’s recovery of such expenses by the amount exceeding the authorized rate of return. Upon approval by the CPUC, the memorandum accounts are transferred to water supply cost balancing accounts. On April 13, 2006, the CPUC approved a decision eliminating the earnings test that limited recovery of expenses recorded in these accounts. The decision also eliminated the need to make an annual filing. Pursuant to this order, GSWC recognized a cumulative under-collection of approximately $636,000 to the supply cost memorandum account provisions in the second quarter of 2006 for the under-collected balances not recognized at March 31, 2006 and began recording under- and over- collections on a monthly basis thereafter commencing with the second quarter of 2006. For the three months ended March 31, 2007 and 2006, approximately, $1.5 million of under-collections and $237,000 of over-collections, respectively, were recorded in the water supply cost memorandum/balancing accounts, including amortization of approximately $320,000 under-collection and $237,000 over-collection, respectively.

GSWC filed advice letters with the CPUC in October 2006 for review of $2.0 million net under-collections of Region I’s 2005 and 2006 water supply cost memorandum account balance as of August 31, 2006 and its net balance after amortization of the 2001-2003 balancing account. On January 3, 2007, the CPUC approved the advice letters as filed. As a result, the total $2.0 million net under-collection was transferred to the water supply cost balancing account in January 2007. There was no impact to earnings in 2007 as this net under-collection was recorded as a regulatory asset in 2006.

Costs Deferred for Future Recovery:

In 1999, GSWC sued Aerojet-General Corporation (“Aerojet”) for contaminating the Sacramento County Groundwater Basin, which affected certain GSWC wells. On a related matter, GSWC also filed a lawsuit against the State of California (the “State”). The CPUC authorized memorandum accounts to allow for recovery, from customers, of costs incurred by GSWC in prosecuting the cases against Aerojet and the State, less any recovery from the defendants or others. On July 21, 2005, the CPUC authorized GSWC to collect approximately $21.3 million of the Aerojet litigation memorandum account, through a rate surcharge, which will continue for no longer than 20 years. Beginning in October 2005, new rates went into effect to begin amortizing the memorandum account over a 20-year period.

A rate surcharge generating approximately $220,000 and $210,000 was billed to customers during the three months ended March 31, 2007 and 2006, respectively. GSWC will keep the Aerojet memorandum account open until the earlier of full amortization of the balance or 20 years. However, no costs will be added to the memorandum account, other than on-going interest charges approved by the decision. Pursuant to the decision, additional interest of approximately $276,000 was added to the Aerojet litigation memorandum account during the three months ended March 31, 2007. It is management’s intention to offset any settlement proceeds from Aerojet that may occur pursuant to the settlement agreement against the balance in the memorandum account, with the exception of an $8.0 million payment guaranteed by Aerojet (for capital investments), with interest due GSWC, to be paid in full over 5 years, beginning in 2009. Pursuant to such settlement agreement, Aerojet has agreed to reimburse GSWC an additional $17.5 million, plus interest accruing from January 1, 2004, for GSWC’s past legal and expert costs. The recovery of the $17.5 million is contingent upon the issuance of land use approvals for development in a defined area within Aerojet property in Eastern Sacramento County and the receipt of certain fees in connection with such development.

On April 7, 2006, GSWC filed an advice letter with the CPUC to incorporate the Westborough development, which represents a portion of the defined property, into the Arden Cordova service area and to provide water service to that new development. The City of Folsom filed a protest of GSWC’s advice letter on April 27, 2006. GSWC and the City of Folsom continue to negotiate a settlement of issues presented in their protest. On January 30, 2007, the CPUC rejected the advice letter without prejudice, and invited GSWC to re-file the advice letter once the City of Folsom protest is resolved, or file an application for CPUC approval of the service territory expansion. GSWC cannot predict the outcome of the City’s protest nor the future development within Aerojet’s property.

Other Regulatory Matters:

On February 15, 2007, the CPUC issued a subpoena to GSWC in connection with an investigation of certain work orders and charges paid to a specific contractor used by GSWC for numerous construction projects. The CPUC’s investigation focuses on whether these charges were approved in customer rates and whether they were just and reasonable. Management cannot predict the outcome of the investigation at this time.

On April 16, 2007, GSWC filed an industry-wide compliance report regarding its historical purchases of energy from renewable generation sources at its Bear Valley Electric operations. The filing indicates that GSWC has not achieved interim target purchase levels established by the CPUC and could be subject to possible fines. Based on the calculation of possible fines included in the filing, the fines can range as high as approximately $592,000. GSWC has contested the possible fines and management does not believe it is probable that GSWC will ultimately be assessed these fines, and accordingly, no provision for loss has been recorded in the financial statements.

Note 3 — Earnings per Share/Capital Stock:

Registrant computes earnings per share (“EPS”) in accordance with EITF No. 03-06, “Participating Securities and the Two-Class Method under FASB Statement No. 128”. EITF No. 03-06 provides the accounting guidance for the effect of participating securities on EPS calculations and the use of the “two-class” method. The guidance requires the use of the “two-class” method of computing EPS for companies with participating securities. The “two-class” method is an earnings allocations formula that determines EPS for each class of common stock and participating security. AWR has participating securities related to stock option and restricted stock units that earn dividend equivalents on an equal basis with Common Shares that have been issued under AWR’s 2000 Stock Incentive Plan and 2003 Non-Employee Directors Stock Plan. In applying the “two-class” method, undistributed earnings are allocated to both Common Shares and participating securities. The following is a reconciliation of Registrant’s net income and weighted average Common Shares outstanding for calculating basic net income per share:

Basic	For The Three Months Ended March 31,
(in thousands, except per share amounts)	2007		2006
Net income	$	6,984	$	5,899
Less: (a) Distributed earnings to common shareholders	4,008		3,781
Distributed earnings to participating securities	86		—
Undistributed earnings	2,890		2,118

(b) Undistributed earnings allocated to common shareholders	2,830		2,075
Undistributed earnings allocated to participating securities	60		43

Total income available to common shareholders, basic (a)+(b)	$	6,838	$	5,856

Weighted average Common Shares outstanding, basic	17,055		16,806
Basic earnings per Common Share	$	0.40	$	0.35

Diluted EPS is based upon the weighted average number of Common Shares including both outstanding shares and shares potentially issuable in connection with stock options and restricted stock units granted under Registrant’s 2000 Stock Incentive Plan and 2003 Non-Employee Directors Stock Plan, and net income. At March 31, 2007 and 2006 there were 704,591 and 770,977 options outstanding, respectively, under these Plans. At March 31, 2007 and 2006, there were also approximately 60,352 and 46,279 restricted stock units outstanding, respectively.

The following is a reconciliation of Registrant’s net income and weighted average Common Shares outstanding for calculating diluted net income per share:

Diluted	For The Three Months Ended March 31,
(in thousands, except per share amounts)	2007		2006
Common shareholders earnings, basic	$	6,838	$	5,856
Undistributed earnings for dilutive stock options (1)	—		—
Total common shareholders earnings, diluted	$	6,838	$	5,856

Weighted average common shares outstanding, basic	17,055		16,806
Stock-based compensation (2)	59		103
Weighted average common shares outstanding, diluted	17,114		16,909
Diluted earnings per Common Share	$	0.40	$	0.35

(1) Undistributed earnings allocated to participating securities were not included due to their antidilutive effect on diluted earnings per share.

(2) In applying the treasury stock method of reflecting the dilutive effect of outstanding stock-based compensation in the calculation of diluted EPS, 297,991 and 366,610 stock options at March 31, 2007 and 2006, respectively, were deemed to be outstanding in accordance with SFAS No. 128, “Earnings Per Share”.

Stock options of 101,090 and 94,917 were outstanding at March 31, 2007 and 2006, respectively, but not included in the computation of diluted EPS because the related option exercise price was greater than the average market price of AWR’s Common Shares for the three months ended March 31, 2007 and 2006. Stock options of 305,510 and 309,450, and restricted stock units of 60,352 and 46,279 were outstanding at March 31, 2007 and 2006, respectively, but not included in the computation of diluted EPS because they were antidilutive.

Registrant has a Shareholder Rights Plan designed to protect the Company’s shareholders in the event of an unsolicited unfair offer to acquire the Company. The rights for Junior Participating Preferred Shares (the “Rights”) are exercisable based solely on “a non-market-based contingency”, and are not contingent upon the market price of the AWR’s stock. Therefore, the shares that would be issued if the Rights are exercised are not included in the calculation of diluted earnings per share.

During the three months ended March 31, 2007 and 2006, Registrant issued 10,532 and 24,101 Common Shares, for approximately $284,000 and $719,000, respectively, under the Registrant’s Common Share Purchase and Dividend Reinvestment Plan, the 401(k) Plan, and the stock incentive plans. In addition, during the three months ended March 31, 2007 and 2006, Registrant purchased 282 and 14,084, respectively, Common Shares on the open market under the Registrant’s Common Share Purchase and Dividend Reinvestment Plan and 401(k) Plan, which were used to satisfy the requirements of these plans.

During the three months ended March 31, 2007 and 2006, AWR paid quarterly dividends to the shareholders of approximately $4.0 million, or $0.235 per share, and $3.8 million, or $0.225 per share, respectively.

Note 4 — Derivative Instruments:

Registrant has certain block-forward purchase power contracts that are subject to SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities”, as amended by SFAS Nos. 138 and 149. A derivative financial instrument or other contract derives its value from another investment or designated benchmark. SFAS No. 133 requires companies to record derivatives on the balance sheet as assets and liabilities, and to measure those instruments at their fair value. Certain of these contracts qualify as an exception provided under SFAS No. 133 for activities that are considered normal purchases and normal sales. These contracts are reflected in the statements of income at the time of contract settlement.

During 2002, GSWC became a party to block-forward purchase power contracts that qualified as derivative instruments under SFAS No. 133. Contracts with Pinnacle West Capital Corporation which became effective in November 2002 have not been designated as normal purchases and normal sales. As a result, on a monthly basis, the related asset or liability is adjusted to reflect the fair market value at the end of the month. For the three months ended March 31, 2007 and 2006, GSWC recognized a pretax unrealized gain of $2.7 million and a pretax unrealized loss of $2.2 million, respectively. As this contract is settled, the realized gains or losses are recorded in power purchased for resale, and the previously recorded unrealized gains or losses are reversed. These contracts have been recognized at fair market value on the balance sheets resulting in a cumulative unrealized loss of $944,000 as of March 31, 2007.

The market prices used to determine the fair value for this derivative instrument were estimated based on independent sources such as broker quotes and publications. Settlement of this contract occurred on a cash or net basis through 2006 and by physical delivery thereafter through 2008. Registrant has no other derivative financial instruments.

Note 5 — Income Taxes:

As a regulated utility, GSWC treats certain temporary differences as flow-through adjustments in computing its income tax provision consistent with the income tax approach approved by the CPUC for ratemaking purposes. Flow-through adjustments increase or decrease tax expense in one period, with an offsetting increase or decrease occurring in another period. Giving effect to these temporary differences as flow-through adjustments typically results in a greater variance between the effective tax rate (“ETR”) and the statutory federal income tax rate in any given period than would otherwise exist if GSWC were not required to account for its income taxes as a regulated enterprise.

In July 2006, the FASB issued FIN 48. FIN 48 clarifies the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. Effective January 1, 2007, Registrant adopted FIN 48. As a result of adoption, Registrant increased retained earnings by $181,000. As of the adoption date and at March 31, 2007, Registrant’s total amount of unrecognized tax benefits was $4.8 million, of which $118,000, if recognized, would affect the effective tax rate.

With the adoption of FIN 48, Registrant continued its policy of classifying interest on income tax over/underpayments in interest income/expense and penalties in “other operating expenses.” At March 31, 2007, Registrant included $362,000 of net interest receivables from taxing authorities in other assets ($92,000 as current), of which $41,000 was included in interest income for the three months ended March 31, 2007. For the three months ended March 31, 2006, Registrant did not recognize any income-tax-related interest income or expense. At March 31, 2007, Registrant had no accruals for income-tax-related penalties and did not recognize any such penalty expense during the three months ended March 31, 2007 and 2006.

Registrant files income tax returns in the U.S. federal and various state jurisdictions. The U.S. federal filings for the years 1997 through 1999 and 2002 came under examination during the three months ended March 31, 2007 as a result of Registrant having filed an amended 2002 return during the third quarter of 2006 for which Internal Revenue Service (“IRS”) and Congressional Joint Committee of Taxation (“JCT”) reviews are required. The 2002 return was amended primarily as a result of the IRS consenting to Registrant’s request for approval to change a tax accounting method. In relation to this consent, Registrant’s total amount of unrecognized tax benefits could significantly increase or decrease within twelve months of March 31, 2007. An estimate of the range of the reasonably possible change cannot be made at March 31, 2007. Registrant is unable to anticipate when the IRS and JCT reviews will be concluded.

The California filing for 2001 also came under examination during the three months ended March 31, 2007 as a result of Registrant having filed an amended 2001 return in the first quarter of 2006. Registrant anticipates that the California review will be completed by December 31, 2007.

Other than the years currently under examination, as discussed above, Registrant’s 2003 through 2005 tax years remain subject to examination by the IRS and its 2002 through 2005 tax years remain subject to examination by state taxing authorities.

There was no material difference between AWR and GSWC in regards to the adoption of FIN 48.

Note 6 — Employee Benefit Plans:

The components of net periodic benefit costs, before allocation to the overhead pool, for Registrant’s pension plan, postretirement plan, and Supplemental Executive Retirement Plan (“SERP”) for the three months ended March 31, 2007 and 2006 are as follows:

	Pension Benefits						Other Postretirement Benefits						SERP
(dollars in thousands)	2007			2006			2007			2006			2007			2006
Components of Net Periodic Benefits Cost:
Service cost	$	980		$	991		$	105		$	107		$	106		$	32
Interest cost	1,261			1,175			168			155			41			35
Expected return on plan assets	(1,122		)	(984		)	(57		)	(50		)	—			—
Amortization of transition	—			—			105			105			—			—
Amortization of prior service cost	41			41			(50		)	(50		)	40			37
Amortization of actuarial (gain) loss	171			292			25			37			(6		)	(3		)
Net periodic pension cost	$	1,331		$	1,515		$	296		$	304		$	181		$	101

Registrant expects to contribute a minimum of approximately $4,215,000 and $800,000 to pension and postretirement medical plans in 2007, respectively. No contributions were made during the three months ended March 31, 2007.

Note 7 — Contingencies:

Water Quality-Related Litigation:

In 1997, GSWC was named as a defendant in nineteen lawsuits that alleged that GSWC and other water utilities delivered unsafe water to their customers in the San Gabriel Valley and Pomona Valley areas of Los Angeles County. Plaintiffs in these actions sought damages, including general, special, and punitive damages, as well as attorney’s fees on certain causes of action, costs of suit, and other unspecified relief. On August 4, 2004, GSWC was dismissed from all nineteen Los Angeles County cases. The Court found GSWC did not violate established water quality standards and dismissed the cases after allowing reasonable time and opportunity for the plaintiffs to prove otherwise. GSWC has long asserted that it provides water within the standards established by the health authorities. On September 21, 2004, GSWC received notice that several plaintiffs filed an appeal to the trial court’s order to dismiss GSWC. Briefs and reply briefs on the appeal have been filed. On February 7, 2006, the Second Appellate District in which the briefs were filed moved the California Supreme Court to transfer the appeal to the First Appellate District, the District in which prior appeals regarding these cases had been heard. The Supreme Court granted the transfer and the appeal is currently pending before the First Appellate District. GSWC is unable to predict the outcome of this appeal.

GSWC is subject to self-insured retention (deductible) provisions in its applicable insurance policies and has either expensed the self-insured amounts or has reserved against payment of these amounts as appropriate. GSWC’s various insurance carriers have, to date, provided reimbursement for much of the costs incurred above the self-insured amounts for defense against these lawsuits, subject to a reservation of rights. In addition, the CPUC has issued certain decisions, which authorize GSWC to establish a memorandum account to accumulate costs for future recovery.

Perchlorate and/or Volatile Organic Compounds (“VOC”) have been detected in five wells servicing GSWC’s San Gabriel System. GSWC filed suit in federal court, along with two other affected water purveyors and the San Gabriel Basin Water Quality Authority (“WQA”), against some of those allegedly responsible for the contamination of two of these wells. Some of the other potential defendants settled with GSWC, other water purveyors and the WQA (the “Water Entities”) on VOC related issues prior to the filing of the lawsuit. In response to the filing of the Federal lawsuit, the Potentially Responsible Party (“PRP”) defendants filed motions to dismiss the suit or strike certain portions of the suit. The judge issued a ruling on April 1, 2003 granting in part and denying in part the potentially responsible party’s motions. A key ruling of the court was that the water purveyors, including GSWC, by virtue of their ownership of wells contaminated with hazardous chemicals are themselves PRPs under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”).

Registrant has, pursuant to permission of the court, amended its suit to claim certain affirmative defenses as an “innocent” party under CERCLA. Registrant is presently unable to predict the outcome of this ruling on its ability to fully recover from the PRPs future costs associated with the treatment of these wells. In this same suit, the PRPs have filed cross-complaints against the Water Entities, the Metropolitan Water District, the Main San Gabriel Basin Watermaster and others on the theory that they arranged for and did transport contaminated water into the Main San Gabriel Basin for use by Registrant and the other two affected water purveyors and for other related claims.

On August 29, 2003, the US Environmental Protection Agency (“EPA”) issued Unilateral Administrative Orders (“UAO”) against 41 parties deemed responsible for polluting the groundwater in that portion of the San Gabriel Valley from which two of GSWC’s impacted wells draw water. GSWC was not named as a party to the UAO. The UAO requires that these parties remediate the contamination. The judge in the Federal lawsuit has appointed a special master to oversee mandatory settlement discussions between the PRPs and the Water Entities. EPA is also conducting settlement discussions with several PRPs regarding the UAO. The Water Entities and EPA are working to coordinate their settlement discussions under the special master in order to arrive at a complete resolution of all issues affecting the Federal lawsuits and the UAO. Settlements with a number of the PRPs are being finalized; however, Registrant is presently unable to predict the ultimate outcome of these settlement discussions.

Registrant is unable to predict an estimate of the loss, if any, resulting from any of these suits or administrative proceedings.

Condemnation of Properties:

The laws of the State of California and the State of Arizona provide for the acquisition of public utility property by governmental agencies through their power of eminent domain, also known as condemnation, where doing so is necessary and in the public interest. In addition, however, the laws of the State of California also provide: (i) that the owner of utility property may contest whether the condemnation is actually necessary and in the public interest, and (ii) that the owner is entitled to receive the fair market value of its property if the property is ultimately taken.

Although the City of Claremont, California located in GSWC’s Region III, has not initiated the formal condemnation process pursuant to California law, the City has expressed various concerns to GSWC about the rates charged by GSWC and the effectiveness of the CPUC’s rate setting procedures. The City hired a consultant to perform an appraisal of the value of Registrant’s water system serving the City. The value was estimated in 2004 by the consultant at $40 - $45 million. GSWC disagrees with the City’s valuation assessment. As of March 31, 2007, management believes that the fair market value of the system exceeds the $38.5 million recorded net book value and also exceeds the consultant’s estimates of the Claremont water system.

The Town of Apple Valley is located in GSWC’s Region III and was evaluating the potential takeover of GSWC’s Apple Valley water systems as well as the water systems of another utility serving the Town. On March 13, 2007, the Town Council voted to formally abandon its review of the potential acquisition. GSWC was notified of the Town Council’s action by a letter from the Town Manager dated April 3, 2007.

Except for the City of Claremont and the Town of Apple Valley, Registrant has not been, within the last three years, involved in activities related to the potential condemnation of any of its 38 other water customer service areas or in its Bear Valley Electric customer service area. No formal condemnation proceedings have been filed against any of the Registrant’s properties during the past three years.

Santa Maria Groundwater Basin Adjudication:

In 1997, the Santa Maria Valley Water Conservation District (“plaintiff”) filed a lawsuit against multiple defendants, including GSWC, the City of Santa Maria, and several other public water purveyors. The plaintiff’s lawsuit seeks an adjudication of the Santa Maria Groundwater Basin. A settlement of the lawsuit has been reached, subject to CPUC approval. The settlement, among other things, if approved, would preserve GSWC’s historical pumping rights and secure supplemental water rights for use in case of drought or other reductions in the natural yield of the Basin. There are also a few nonsettling parties, and the case is going forward as to these parties. The stipulation, if approved, would preserve GSWC’s position with the settling parties independent of the outcome of the case as it moves forward with the nonsettling parties.

From 1997 through March 31, 2007, GSWC has incurred costs of approximately $6.4 million in defending its rights in the Santa Maria Basin, including legal and expert witness fees, which have been recorded in Utility Plant for rate recovery. In February 2006, GSWC filed an application with the CPUC for recovery of $5.5 million of these costs, representing the amount of the costs that had been incurred as of December 31, 2005. In February 2007, GSWC reached a settlement with the Division of Ratepayer Advocates authorizing recovery of the $5.5 million requested in GSWC’s application. The settlement

deferred review of the remaining legal costs pending final resolution of the lawsuit. On April 16, 2007 the assigned Administrative Law Judge issued a proposed decision that approved the settlement with the Division of Ratepayer Advocates and the Orcutt Advisory Group. Management believes the proposed decision will be approved and the recovery of these costs through rates is probable.

Air Quality Management District:

In 1998, the South Coast Air Quality Management District (“AQMD”) issued a permit to GSWC for the installation and use of air stripping equipment at one of GSWC’s groundwater treatment systems in its Region II service area. In 2005, the AQMD conducted an inspection of this facility and issued a Notice of Violation (“NOV”) for exceeding the amount of groundwater permitted to be treated by the treatment system during calendar year 2004. Since receiving the NOV, changes in GSWC procedures have prevented additional violations at the facility. The AQMD could assess penalties associated with an NOV that can range from $10,000 up to $75,000 per day of violation. GSWC estimates that it was in violation approximately 180 days in 2004. GSWC has met with AQMD to ensure future compliance and resolve the NOV. As part of this process, GSWC also submitted an application to amend the permit, because an amendment may have been necessary for continued operation of the subject air stripping equipment.

The AQMD has recently recommended that GSWC be allowed to pursue a Supplemental Environmental Program (“SEP”) as part of the settlement of the NOV. A SEP typically involves capital expenditures resulting in a change of process, equipment, material, or indirect source reduction for the purposes of eliminating or reducing air contaminant emissions. As part of pursuing its permit amendment application, GSWC would include further controls to the facility to reduce emissions. The anticipated penalties for the 2004 violations might be reduced or avoided through the settlement of this matter based on the funding of a SEP. In October 2006, GSWC submitted initial capital cost estimates to the AQMD for the installation and operation of granular activated carbon filters at the facility as a proposed SEP. Installation of the filters would eliminate the use of the air stripping equipment at the facilities involved with the NOV and thus improve air quality. Initial and follow-up discussions indicated that AQMD staff has favorably received GSWC’s proposal and if approved, it could result in the imposition of only a nominal monetary penalty for the 2004 violations. In April 2007, GSWC submitted the final SEP and is waiting for AQMD approval. However, until further notice from the AQMD on the SEP, GSWC cannot reasonably estimate the outcome of the NOV and any amount of penalties which might be assessed.

Other Litigation:

An officer of the Company has asserted a potential claim against the Company for retaliation against the officer and others in connection with alleged discriminatory conduct by the Company and its Board of Directors. Although management believes that the allegations are without merit and intends to vigorously defend against them, the Company retained an independent investigator to review the allegations and investigate the facts. Based upon the results of such investigation, the Company does not believe that the ultimate resolution of this matter will have a material adverse effect on its financial position, results of operations, or cash flows.

Registrant is also subject to other ordinary routine litigation incidental to its business. Management believes that rate recovery, proper insurance coverage and reserves are in place to insure against property, general liability and workers’ compensation claims incurred in the ordinary course of business.

Note 8 — Business Segments:

AWR has three reportable segments, water, electric and contract operations, whereas GSWC has two segments, water and electric. Within the segments, AWR has three principal business units: water and electric service utility operations conducted through GSWC, a water-service utility operation conducted through CCWC, and a contracted services unit conducted through ASUS and its subsidiaries. All activities of GSWC are geographically located within California. All activities of CCWC are located in the state of Arizona. Activities of ASUS and its subsidiaries are conducted in California, Maryland, Texas and Virginia. Both GSWC and CCWC are regulated utilities. On a stand-alone basis, AWR has no material assets other than its investments in its subsidiaries. The tables below set forth information relating to GSWC’s operating segments, CCWC, ASUS and its subsidiaries, and other matters. Certain assets, revenues and expenses have been allocated in the amounts set forth. The identifiable assets are net of respective accumulated provisions for depreciation.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”), American States Utility Services, Inc. (“ASUS”) and its subsidiaries, and Chaparral City Water Company (“CCWC”). AWR was incorporated as a California corporation in 1998 as a holding company.

GSWC is a California public utility company engaged principally in the purchase, production and distribution of water. GSWC also distributes electricity in one customer service area. GSWC is regulated by the California Public Utilities Commission (“CPUC”) and was incorporated as a California corporation on December 31, 1929. GSWC is organized into one electric customer service area and three water service regions consisting of 21 customer service areas operating within 75 communities in 10 counties in the State of California. Region I consists of 7 customer service areas in northern and central California; Region II consists of 4 customer service areas located in Los Angeles County; and Region III consists of 10 customer service areas in eastern Los Angeles County, and in Orange, San Bernardino and Imperial counties. GSWC also provides electric service to the City of Big Bear Lake and surrounding areas in San Bernardino County through its Bear Valley Electric service division. GSWC served 254,097 water customers and 23,206 electric customers at March 31, 2007, or a total of 277,303 customers, compared with 276,362 total customers at March 31, 2006. GSWC’s utility operations exhibit seasonal trends. Although GSWC’s water utility operations have a diversified customer base, residential and commercial customers account for the majority of GSWC’s water sales and revenues. Revenues derived from commercial and residential water customers accounted for approximately 90% of total water revenues for the three months ended March 31, 2007 and 2006.

CCWC is an Arizona public utility company serving 13,395 customers as of March 31, 2007, compared with 13,117 customers at March 31, 2006. Located in the town of Fountain Hills, Arizona and a portion of the City of Scottsdale, Arizona, the majority of CCWC’s customers are residential. The Arizona Corporation Commission (“ACC”) regulates CCWC.

ASUS contracts, either directly or through wholly-owned subsidiaries, with the U.S. government and various municipalities and private entities to provide water and wastewater services, including the operation and maintenance of water and wastewater systems, billing and meter reading and water marketing. ASUS commenced operation and maintenance of water and wastewater systems through a wholly-owned subsidiary at its first military base in Texas in October 2004. Since that date, ASUS commenced operation and maintenance of water and wastewater systems at military bases through wholly-owned subsidiaries in Maryland and Virginia in February 2006 and April 2006, respectively. All of these contracts have a 50-year term, subject to termination for convenience by the U.S. government. The contract price for each of these contracts is subject to redetermination two years after commencement of operations and every three years thereafter to the extent provided in each of the contracts. Prices are also subject to equitable adjustment based upon changes in circumstances and changes in wages and fringe benefits to the extent provided in each of the contracts. In addition, a subsidiary of ASUS has executed a contract for the construction of infrastructure improvements on a military base in Texas. This contract is a fixed-price contract. Prices may be increased by the execution of change orders if significant unforeseen issues are encountered during construction that would increase overall costs. Revenues are recognized on the percentage-of-completion method for this contract.

ASUS and GSWC have been pursuing an opportunity to provide contract services for wastewater treatment and retail water services respectively, within the service area of the Natomas Central Mutual Water Company (“Natomas”). Natomas is a California mutual water company which currently provides water service to its shareholders, primarily for agricultural irrigation in portions of Sacramento and Sutter counties in northern California. In August 2004, Natomas and ASUS entered into a contract under which ASUS acts as the exclusive agent for marketing water that has become “temporarily surplus” to the internal needs of Natomas, and that arises under water rights permits and contracts owned or controlled by Natomas, to third parties outside the Natomas service area. On January 31, 2006, ASUS and Natomas entered into a water purchase and sale agreement under which ASUS will acquire 5,000 acre-feet of permanent Sacramento River water diversion rights from Natomas. Pursuant to the terms of this agreement, Natomas will sell, transfer and convey to ASUS, in perpetuity, water rights and entitlements to divert from the Sacramento River up to 5,000 acre-feet of water per year, subject to certain regulatory approvals. Terms of the acquisition, among other things, include a base price of $2,500 per acre-foot of water, with payments contingent on achievement of specific milestones and events over a 10-year period. Pursuant to the marketing services agreement described above, Natomas will pay to ASUS a commission of 16% of the sale price over the same 10-year period for any “temporary surplus” water marketed by ASUS. At the same time that the water purchase agreement was completed, Natomas and ASUS also entered into a settlement agreement that released Natomas from previously established reimbursement obligations under prior agreements. ASUS may use the water rights acquired from Natomas to serve existing customers, to re-sell to other beneficial users, or to pursue and serve expanded service territories.

GSWC and Natomas have also entered into a water transfer agreement under which GSWC agreed to purchase and Natomas agreed to sell up to 30,000 acre-feet of water to be used exclusively by GSWC to serve customers in Sutter County, California. Additionally, GSWC filed for a Certificate of Public Convenience and Necessity with the CPUC on May 31, 2006 to provide retail water service in a portion of Sutter County, California. CPUC review of the application has been deferred pending completion of an environmental assessment for the proposed new water service. All of the agreements with Natomas are subject to receipt of various regulatory approvals required for their full implementation.

Overview

Our revenues, operating income, and cash flows are earned primarily through delivering drinking water to homes and businesses via over 2,900 miles of water distribution pipelines. Rates charged to customers of GSWC and CCWC are determined by either the CPUC or ACC. These rates are intended to allow recovery of operating costs and a reasonable rate of return on capital. Factors recently affecting our financial performance include the process and timing of setting rates charged to customers; our ability to recover, and the process for recovering in rates, the costs of distributing water and electricity; weather; the impact of increased water quality standards on the cost of operations and capital expenditures; pressures on water supply caused by population growth, more stringent water quality standards, deterioration in water quality and water supply from a variety of causes; capital expenditures needed to upgrade water systems and increased costs and risks associated with litigation relating to water quality and water supply, including suits initiated by the Company to protect its water supply.

We plan to continue to seek additional rate increases in future years to recover our operating and supply costs and receive reasonable returns on invested capital. Capital expenditures in future years are expected to remain at much higher levels than depreciation expense. Cash solely from operations is not expected to be sufficient to fund our needs for capital expenditures, dividends, investments in our contract business and other cash requirements. We expect to fund these needs through a combination of debt and common stock offerings in the ensuing years. AWR expects to issue equity in late 2007.

Operating revenues and income from our contracted services are earned primarily from the operation and maintenance of water and wastewater systems for the U.S. government at various military bases. All of the operations and maintenance contracts with the U.S. government are 50-year fixed-price redetermination-prospective contracts. We also may generate revenues from the construction of infrastructure improvements at these bases pursuant to the terms of these 50-year contracts or pursuant to supplemental contracts. Revenues generated by our contract operations are primarily dependent on these new business activities, including military base operations and the construction of new and/or replacement infrastructures at these military bases. As a result, we are subject to risks that are different than those of our regulated water and electric activities. We plan to continue seeking opportunities to bid on other contracts for the privatization of water and wastewater services at military bases.

Summary Results by Segment

AWR has three reportable segments: water, electric and contracts operation. Within the segments, AWR has three principal business units: water and electric service utility operations conducted through GSWC, a water-service utility operation conducted through CCWC, and a contracted services unit through ASUS and its subsidiaries. The tables below set forth summaries of the results by segment (in thousands):

Water - For the three months ended March 31, 2007, operating income for water decreased by $3.1 million, or 22%, primarily due to a decision issued by the CPUC on April 13, 2006 regarding GSWC’s water rights lease revenues received from the City of Folsom. This decision added about $2.3 million of additional revenues in the first quarter of 2006 for amounts that had been received from the City of Folsom in 2004 and 2005. Prior to the decision, this amount had been recorded as a regulatory liability. This decision allowed GSWC to recognize revenue in the first quarter of 2006 without a corresponding amount in 2007, except for the on-going annual Folsom lease revenues of approximately $1.3 million. Higher

operating expenses as described below also contributed to the decrease in water’s operating income, offset by increased water rates approved by the CPUC that were effective January 1, 2007 and an increase in water consumption over that in the prior period.

Electric - For the three months ended March 31, 2007, operating income for electric increased by $4.7 million. There was an unrealized gain on Bear Valley Electric’s purchased power contracts in the first quarter of 2007 due to increasing energy prices versus an unrealized loss on purchased power contracts in the same quarter of 2006. The unrealized gain on purchased power contracts increased operating income by approximately $2.7 million for the three months ended March 31, 2007, as compared to an unrealized loss on purchased power contracts that decreased operating income by $2.2 million for the same period in 2006.

Contracted Services - For the three months ended March 31, 2007, operating income for contracted services increased by $1.2 million. This was primarily due to a new contract with the U.S. government. In December 2006, a subsidiary of ASUS finalized an agreement with the U.S. government for the construction of certain improvements to the existing wastewater infrastructure located at Fort Bliss in El Paso, Texas. The $19.8 million project is a firm-fixed price contract, subject to change orders if significant issues are encountered during construction that would increase the overall cost of the project. This construction project is an amendment and supplemental to the 50-year contract with the U.S. government to manage the entire water and wastewater systems at Fort Bliss. In March 2007, ASUS executed a formal change order to this contract amendment. The change order contained a value of approximately $765,000 thus increasing total revenues to be recognized on this contract amendment to $20.6 million. Revenues from this agreement are being recognized on the percentage-of-completion method. As a result of this new project, operating income increased by $2.2 million during the first quarter of 2007. The project is scheduled to be completed by August 15, 2007. Partially offsetting this increase was the recovery and reimbursement in 2006 of transition period operating expenses of about $672,000 as a result of operating and maintaining the water and wastewater systems under new contracts at military bases in Virginia and Maryland pursuant to the contracts with the U.S. government. We took over the operation and maintenance of the water and wastewater systems at Andrews Air Force Base in Maryland on February 1, 2006 and commenced operation of these systems on that date. In addition, we assumed the operation and maintenance of the wastewater systems at Fort Lee in Virginia on February 23, 2006 and the water and wastewater systems at Fort Eustis, Fort Monroe and Fort Story in Virginia on April 3, 2006 and commenced operation and maintenance of these systems on those dates. Therefore, we operated these bases partially during the first quarter of 2006 and entirely during same period of 2007.

The following discussion and analysis provides information on AWR’s consolidated operations and assets. For the three months ended March 31, 2007 and 2006, there is generally no material difference between the consolidated operations and assets of AWR and the water and electric operations and assets of GSWC. However, where necessary, the following discussion and analysis includes references specifically to AWR’s individual segments and/or other subsidiaries — CCWC and ASUS and its subsidiaries.

Net income for the first quarter ended March 31, 2007 increased by 18.4% to $7.0 million, equivalent to $0.40 per common share on both a basic and fully diluted basis, compared to $5.9 million or $0.35 per share for the three months ended March 31, 2006. Impacting the comparability in the results of the two periods are the following significant items:

· There was an unrealized gain on purchased power contracts in 2007 due to increasing energy prices versus an unrealized loss on purchased power contracts in 2006. The cumulative unrealized gain on purchased power contracts increased pretax income by approximately $2.7 million, or $0.09 per share, for the three months ended March 31, 2007, as compared to a cumulative unrealized loss on purchased power contracts that decreased pretax income by $2.2 million, or $0.08 per share, for the same period in 2006.

· A decision issued by the CPUC on April 13, 2006 regarding the treatment of GSWC’s water rights lease revenues increased pre-tax income by about $2.3 million in March 2006, or approximately $0.08 per share, over the same period in 2007. Pursuant to a March 2004 CPUC order, the apportionment of any Folsom lease revenues that GSWC may collect commencing in January 2004 was to be determined by a later decision. Pending that later decision and beginning in the first quarter of 2004, all amounts billed to the City of Folsom had been included in a regulatory liability account and no amounts were recognized as revenue until uncertainties about this matter were resolved with the CPUC. On April 13, 2006, the CPUC authorized GSWC to reinvest all lease revenues since January 2004, inclusive of the balances in the regulatory liability accounts established by GSWC for this matter, in water system infrastructure. These investments will be included in the rate base upon which GSWC earns a rate of return. In accordance with California law, GSWC has 8 years in which to reinvest the proceeds, after which any amount remaining would inure to the customer’s benefit. As a result, GSWC transferred about $2.3 million of water rights lease revenues received from the City of Folsom in 2004 and 2005 from the regulatory liability account into revenues.

· An increase in ASUS’s pretax operating income of $1.2 million, or $0.04 per share, as compared to the same period of 2006 for operating, maintaining and improving the water and wastewater systems at military bases for the U.S. government. The increases include revenue recognized for certain special projects under the percentage-of-completion method of accounting.

· Higher operating expenses, changes in the effective tax rate, as well as other items described below, contributed to an overall decrease of $0.08 per share to the results of operations.

Operating Revenues

For the three months ended March 31, 2007, revenues from water operations decreased slightly by 0.8% to $50.3 million, compared to $50.8 million for the three months ended March 31, 2006. Contributing to this decrease was a CPUC decision issued on April 13, 2006 enabling GSWC to record $2.3 million in the first quarter of 2006 of water rights lease revenues from the City of Folsom for the period from January 2004 to December 2005. Prior to this decision, the apportionment of any lease revenues that GSWC collected in 2004 and 2005 had been included in a regulatory liability account and no amounts were recognized as revenues until regulatory uncertainties about this matter were resolved. There was no such adjustment in the first quarter of 2007. For the first quarter of 2007 and 2006, GSWC also recorded water lease revenues from the City of Folsom totaling $311,000 and $299,000, respectively. This decrease was partially offset by rate increases approved by the CPUC and effective January 1, 2007, which contributed approximately $1.7 million in increased water revenues. In addition, an increase of about 1.0% in billed water consumption resulting from changes in weather conditions increased revenues by approximately $190,000. Differences in temperature and rainfall in Registrant’s service areas impact sales of water to customers, causing fluctuations in Registrant’s revenues and earnings between comparable periods.

For the three months ended March 31, 2007, revenues from electric operations increased by 6.3% to $8.9 million compared to $8.3 million for the three months ended March 31, 2006. The increase reflects higher kilowatt-hour usage by residential customers due to cooler weather conditions. However, this increase was partially offset by a decrease from our industrial customers resulting from less usage of snow-making machines. Last year, warm weather until late January allowed industrial customers to continue making snow. Therefore, more energy was used during February and March of 2006 compared to the same period this year.

Registrant relies upon rate approvals by state regulatory agencies in California and Arizona in order to recover operating expenses and provide for a return on invested and borrowed capital used to fund utility plant. Without such adequate rate relief granted in a timely manner, revenues and earnings can be negatively impacted.

For the three months ended March 31, 2007, revenues from contracted services increased by $7.9 million, or 150.5%, to $13.1 million compared to $5.2 million for the three months ended March 31, 2006 due primarily to an increase of approximately $7.3 million related to construction revenues earned from the U.S. government recognized on the percentage-of completion method. The revenues earned were for the construction of certain improvements, renewals and replacements to the existing water and wastewater infrastructures at Fort Bliss and at other military bases located in Virginia and Maryland pursuant to new operation and maintenance contracts entered into in early 2006. Certain of the construction projects are firm, fixed-price contracts and are supplemental to ASUS’s 50-year contracts with the U.S. government. There were also additional revenues totaling $709,000 in the first quarter of 2007 generated from operating and maintaining the water and wastewater systems under the new contracts in Virginia and Maryland.

Operating Expenses:

Supply Costs

Water supply costs consist of purchased water, purchased power for pumping, groundwater production assessment and water supply cost balancing accounts. Electric supply costs consist of purchased power for resale and electric supply cost balancing account. Water and electric margins are computed by taking total revenues, less total supply costs. We use margins and related percentages as an important measure in evaluating our operating results. We believe this non-GAAP measure to be key in evaluating our utility business performance within our water and electric segments. We review these measurements regularly and compare them to historical periods and to our operating budget as approved. However, this non-GAAP measure may not be comparable to similarly titled measures used by other entities and should not be considered as an alternative to operating income, which is determined in accordance with GAAP, as an indicator of operating performance.

Total supply costs comprise the largest segment of total operating expenses. Supply costs accounted for approximately 30% and 34% of total operating expenses for the three months ended March 31, 2007 and 2006, respectively. The table below provides the amount of increases (decreases), percent changes in supply costs, and margins during the three months ended March 31, 2007 and 2006 (amounts in thousands):

(1) As reported on AWR’s Consolidated Statements of Income, except for supply cost balancing accounts. The sum of water and electric supply cost balancing accounts in the table above are shown on AWR’s Consolidated Statements of Income and totaled ($720,000) and $487,000 for the three months ended March 31, 2007 and 2006, respectively.

(2) Water and electric margins do not include any depreciation and amortization, maintenance expense, or other operating expenses.

Two of the principal factors affecting water supply costs and gross margin are the amount of water produced and the source of the water. Generally, water from wells costs less than water purchased from wholesale suppliers. In addition, GSWC is authorized to establish water and electric supply cost balancing/memorandum accounts for increases and/or decreases in costs due to changes in rates charged by its suppliers providing our purchased water and purchased power, and by agencies assessing groundwater related pump taxes for our water service areas in California. Higher or lower rates in actual costs as compared to rates authorized by the CPUC will either be recovered from or refunded to customers in the future. However, changes in the water resource mix between water supplied from purchased sources and that supplied from Registrant’s own wells can increase/decrease actual supply-related costs relative to that approved for recovery through rates, thereby impacting

earnings either negatively or positively. GSWC has the opportunity to change the supply-related costs recovered through rates by application to the appropriate regulatory body. GSWC believes that its applications for recovery of supply-related costs accurately reflect the water supply situation as it is known at the time. Without a “full-cost” balancing account authorized by the CPUC, it is impossible to adequately protect earnings from adverse changes in supply costs related to unforeseen contamination or other loss of water supply.

For the three months ended March 31, 2007, 38.9% of the Company’s water supply mix was purchased as compared to 43.2% purchased for the three months ended March 31, 2006. This change in mix resulted in improved margins in 2007 compared to same period in 2006. Water gross margin for the first quarter of 2006 included the $2.3 million water rights lease revenues from the City of Folsom.

Purchased water costs increased by 6.3% to $8.9 million compared to $8.3 million for the three months ended March 31, 2006. The increase is due primarily to an increase in water supply demand resulting from higher customer consumption and increased water rates charged by purchased water suppliers. In general, the supply cost memorandum account as discussed above allows GSWC to track incremental rate changes from suppliers, for future recovery in water rates. In addition, GSWC entered into a one-time lease of pumped water rights with the City of Pomona in order to allow GSWC to pump more water. The price of this lease paid by GSWC totaled $226,000 and was for 1,000 acre-feet of stored water in eastern Los Angeles County. There were no water rights leased by GSWC from others in the same period of 2006. These increases were offset by a favorable change in the supply mix discussed above, caused by less purchased water needed to replace groundwater supply not pumped in the prior year. Certain wells had been removed from service in 2006 as a result of water quality issues and mechanical problems.

For the three months ended March 31, 2007, the increases in power purchased for pumping and groundwater production assessments were due to higher water supply demand and an increase in pumping volume resulting from the favorable supply mix change as discussed. There were also increases in assessment rates levied against groundwater production, effective July 2006. Average pump tax rates increased in Regions II and III by approximately 2% and 4%, respectively. Again, the supply cost memorandum account tracks the increases in pump tax rates for future recovery in water rates.

A decrease of $1.8 million during the three months ended March 31, 2007 in the water supply cost balancing account provision as compared to the three months ended March 31, 2006 was primarily due to the recording of $1.2 million in net under-collections to the 2007 memorandum account, caused by increased rates in purchased water and purchased power for pumping charged by GSWC’s suppliers and increased pump tax rates. Under-collections in the memorandum account were not recorded in the first quarter of 2006 due to the CPUC’s earning test requirement, which was eliminated in April 2006 by a CPUC decision. Under-collections are now recorded on a monthly basis. There was also a $558,000 decrease in the amortization of the water supply cost balancing accounts due to the expiration in October 2006 of the amortization of Region III’s under-collection.

For the three months ended March 31, 2007, the cost of power purchased for resale to customers in GSWC’s Bear Valley Electric division decreased by 6.2% to $4.3 million compared to $4.6 million for the three months ended March 31, 2006, reflecting an increase in sales to the spot market at higher energy prices. GSWC has a 15MW purchased power agreement with Pinnacle West Capital Corporation (“PWCC”). Purchased power in excess of demand is sold into the spot market at the market price. There was an energy price increase of about $13/MWh, resulting in higher income from sales in the spot market. Income from the spot market sales for the three months ended March 31, 2007 decreased the cost of power purchased for resale and increased the electric supply cost balancing account provision, respectively, as compared to the same period of 2006. This decrease of the cost of power purchased for resale was offset partially by higher customer demand during the first quarter of 2007.

Unrealized (Gain) Loss on Purchased Power Contracts

Unrealized gain and loss on purchased power contracts represent gains and losses recorded for GSWC’s purchased power agreements with PWCC, which qualify as derivative instruments under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities”. The $2.7 million pretax unrealized gain on purchased power contracts for the three months ended March 31, 2007 is due to an increase in the current forward market prices since December 31, 2006. There was a $2.2 million pretax unrealized loss on purchased power contracts for the three months ended March 31, 2006. Unrealized gains and losses at Bear Valley Electric will continue to impact earnings during the life of the contract with PWCC, which terminates at the end of 2008.

Other Operating Expenses

The components of other operating expenses include primarily payroll, material and supplies, chemicals and water treatment, and contract service 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 the three months ended March 31, 2007 and 2006, other operating expenses by segment consisted of the following:

	3 Mos. Ended 3/31/2007		3 Mos. Ended 3/31/2006		$ CHANGE			% CHANGE
Water Services	$	5,451	$	4,260	$	1,191		28.0	%
Electric Services	390		429		(39		)	(9.1	)%
Contracted Services	756		11		745			6772.7	%
Total other operating expenses	$	6,597	$	4,700	$	1,897		40.4	%

For the three months ended March 31, 2007, other operating expenses for water services increased by $1.2 million due primarily to higher chemicals and water treatment costs, including supplies and materials, of $714,000 in particular at GSWC’s Region II and III services area. Region II incurred an additional $4
