Accounting Policies [Abstract]
Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Operations: American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”), Bear Valley Electric Service, Inc. ("BVESI"), and American States Utility Services, Inc. (“ASUS”) (and its subsidiaries, Fort Bliss Water Services Company (“FBWS”), Terrapin Utility Services, Inc. (“TUS”), Old Dominion Utility Services, Inc. (“ODUS”), Palmetto State Utility Services, Inc. (“PSUS”), Old North Utility Services, Inc. (“ONUS”), Emerald Coast Utility Services, Inc. ("ECUS"), and Fort Riley Utility Services, Inc. ("FRUS")). The subsidiaries of ASUS are collectively referred to as the “Military Utility Privatization Subsidiaries.” On July 1, 2020, GSWC completed the transfer of the electric utility assets and liabilities from its electric division to BVESI, a separate legal entity and wholly owned subsidiary of AWR (Note 12). This reorganization is not expected to result in any substantive changes to AWR's operations and business segments. AWR, through its wholly owned subsidiaries, serves over one million people in nine states. GSWC and BVESI are both California public utilities, with GSWC engaged in the purchase, production, distribution and sale of water throughout California serving approximately 261,500 customer connections, while BVESI distributes electricity in several San Bernardino County mountain communities in California serving approximately 24,500 customer connections. The California Public Utilities Commission (“CPUC”) regulates GSWC’s and BVESI's businesses in matters including properties, rates, services, facilities, and transactions between GSWC, BVESI, and their affiliates. ASUS, through its wholly owned subsidiaries, operates, maintains and performs construction activities (including renewal and replacement capital work) on water and/or wastewater systems at various U.S. military bases pursuant to initial 50-year firm fixed-price contracts. These contracts are subject to annual economic price adjustments and modifications for changes in circumstances, changes in laws and regulations and additions to the contract value for new construction of facilities at the military bases. There is no direct regulatory oversight by the CPUC over AWR or the operations, rates or services provided by ASUS or any of its wholly owned subsidiaries. Basis of Presentation: The consolidated financial statements and notes thereto are presented in a combined report filed by two separate Registrants: AWR and GSWC. References in this report to “Registrant” are to AWR and GSWC, collectively, unless otherwise specified. Certain prior period amounts have been reclassified on the statements of cash flows to conform to current year presentation. AWR owns all of the outstanding common shares of GSWC, BVESI, and ASUS. ASUS owns all of the outstanding common stock of the Military Utility Privatization Subsidiaries. The consolidated financial statements of AWR include the accounts of AWR and its subsidiaries. These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). Intercompany 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”). The December 31, 2019 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. 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 revenues and expenses during the reporting period. Actual results could differ from these 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, 2019 filed with the SEC. Related Party Transactions and Financing Activities: GSWC, BVESI, and ASUS provide and/or receive various support services to and from their parent, AWR, and among themselves. GSWC has also allocated certain corporate office administrative and general costs to its affiliates, BVESI and ASUS, using allocation factors approved by the CPUC. GSWC allocated corporate office administrative and general costs to BVESI of approximately $643,000 during the three months ended September 30, 2020. GSWC allocated corporate office administrative and general costs to ASUS of approximately $1.2 million during each of the three months ended September 30, 2020 and 2019, and approximately $3.8 million and $3.5 million during the nine months ended September 30, 2020 and 2019 respectively. AWR borrows under a credit facility, which expires in May 2023, and provides funds to GSWC and ASUS in support of their operations. The interest rate charged to GSWC and ASUS is sufficient to cover AWR’s interest expense under the credit facility. In March 2020, AWR amended the credit facility to temporarily increase the borrowing capacity by $35.0 million to $260.0 million until December 31, 2020, at which point the commitment will be reduced to $200.0 million. As of September 30, 2020, there was $89.0 million outstanding under this facility. Effective July 1, 2020, BVESI put in place and has access to a 3-year, $35 million revolving credit facility. Under the terms of the credit agreement, BVESI has the option to request an increase in the facility by an additional $15 million. As of September 30, 2020, there was $3.0 million outstanding under this facility. On July 8, 2020, GSWC completed the issuance of unsecured private placement notes totaling $160.0 million. In connection with this financing, GSWC issued (i) $85.0 million aggregate principal amount of Series A Senior Notes at a coupon rate of 2.17% due July 8, 2030, and (ii) $75.0 million aggregate principal amount of Series B Senior Notes at a coupon rate of 2.90% due July 8, 2040. Interest on the Notes is payable semiannually. The Notes are unsecured and rank equally with GSWC’s unsecured and unsubordinated debt. GSWC may, at its option, redeem all or portions of the Notes at any time upon written notice, subject to payment of a make-whole premium based on 50 basis points above the applicable treasury yield. Under the terms of the Notes, GSWC may not incur any additional indebtedness or pay any distributions to its parent, AWR, if after giving effect thereto, GSWC would have a total indebtedness to capitalization ratio of more than 0.6667:1.00. In addition, GSWC may not incur any additional indebtedness if, after giving effect thereto, it would have a total indebtedness to earnings before interest, taxes, depreciation and amortization ratio greater than 8.00:1.00. GSWC used the proceeds from the new notes to pay down a majority of the intercompany borrowings from AWR parent. AWR used the proceeds received from GSWC to pay down borrowings on its revolving credit facility. Following the issuance of the notes and effective July 15, 2020, AWR reduced the aggregate borrowing capacity of its credit facility to $200.0 million pursuant to the terms of that credit facility agreement. The CPUC requires GSWC to completely pay down all intercompany borrowings from AWR within a 24-month period. The next 24-month period in which GSWC is required to completely pay down its intercompany borrowings ends in November 2020. As a result, GSWC’s intercompany borrowings of $34.1 million as of September 30, 2020 have been classified as a current liability on GSWC’s balance sheet. COVID-19 Impact: GSWC, BVESI, and ASUS have continued their operations given that their water, wastewater, and electric utility services are deemed essential. The Company's responses take into account the guidance provided by federal, state, and local health authorities and other government officials to the COVID-19 pandemic. Some of the actions taken by GSWC and BVESI include: (i) suspending, at least through April 2021, service disconnections for nonpayment pursuant to CPUC orders; (ii) increasing the number of employees telecommuting; and (iii) delaying some capital improvement projects at the water utility services business. Thus far, the COVID-19 pandemic has not had a material impact on ASUS's operations. The pandemic has caused significant volatility on financial markets, resulting in significant fluctuations in the fair value of plan assets in GSWC's pension and other retirement plans. Management believes this volatility may continue throughout the pandemic. Due to expected future credit losses on utility customer bills, Registrant has increased its allowance for doubtful accounts as of September 30, 2020. However, the CPUC has authorized GSWC and BVESI to track incremental costs, including bad debt expense in excess of what is included in their respective revenue requirements, incurred as a result of the COVID-19 pandemic in a Catastrophic Event Memorandum Account ("CEMA") to be filed with the CPUC for future recovery. GSWC and BVESI have recorded a total of approximately $1.4 million in the CEMA accounts as regulatory assets, as the Company believes such amounts are probable of recovery. Recently Issued Accounting Pronouncements: Accounting Pronouncements Adopted in 2020 In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and issued further guidance in November 2018 and May 2019 related to the impairment of financial instruments, effective January 1, 2020. The new guidance provides an impairment model, known as the current expected credit loss model, which is based on expected credit losses rather than incurred losses over the remaining life of most financial assets measured at amortized cost, including trade and other receivables. For the three and nine months ended September 30, 2020, Registrant has increased its allowance for doubtful accounts for utility customer accounts receivable by $871,000 and $1.9 million, respectively, due to Registrant's current estimate of the expected associated economic impact of the COVID pandemic (see Note 10). Accounting Pronouncements to be Adopted in Future Periods In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits—Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU removes disclosures to pension plans and other retirement plans that no longer are considered cost beneficial, clarifies the specific disclosure requirements and adds disclosure requirements deemed relevant. This ASU is effective for fiscal years ending after December 15, 2020 and will be applied by Registrant on a retrospective basis to all periods presented. Registrant does not believe the ASU will have a material impact on the Company's financial statements and disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740)—Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for income taxes by removing certain exceptions and clarifying certain requirements regarding franchise taxes, goodwill, consolidated tax expenses, and annual effective tax rate calculations. The ASU is effective for fiscal years beginning after December 15, 2020. Early adoption is permitted. Registrant does not believe this ASU will have a material impact on its financial statements.

Revenue from Contract with Customer

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

Revenues

Most of Registrant's revenues are derived from contracts with customers, including tariff-based revenues from its regulated utilities. ASUS's initial 50-year firm fixed-price contracts with the U.S. government are considered service concession arrangements under ASC 853, Service Concession Arrangements. Accordingly, the services under these contracts are accounted for under Topic 606—Revenue from Contracts with Customers, and the water and/or wastewater systems are not recorded as Property, Plant and Equipment on Registrant’s balance sheets.

Although GSWC and BVESI have a diversified base of residential, commercial, industrial, and other customers, revenues derived from residential and commercial customers generally account for approximately 90% of total water and electric revenues. The vast majority of ASUS's revenues are from the U.S. government. For the three and nine months ended September 30, 2020 and 2019, disaggregated revenues from contracts with customers by segment were as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
(dollar in thousands)	2020		2019		2020		2019
Water:
Tariff-based revenues	$	97,036	$	89,050	$	243,553	$	225,501
Surcharges (cost-recovery activities)	1,217		1,900		2,913		2,954

Surcharges (cost-recovery activities)	188		51		624		148
Electric revenues from contracts with customers	8,719		9,780		26,572		28,841
BRRAM (over) under-collection (alternative revenue program)	(431)		2,216		363		1,192
Total electric revenues	8,288		11,996		26,935		30,033

Contracted services:
Water	17,143		13,797		45,316		41,772
Wastewater	9,556		13,454		34,593		40,959
Contracted services revenues from contracts with customers	26,699		27,251		79,909		82,731

Total AWR revenues	$	133,688	$	134,496	$	364,043	$	360,876

The opening and closing balances of the receivable from the U.S. government, contract assets, and contract liabilities from contracts with customers, which are related entirely to ASUS, were as follows:


(dollar in thousands)	September 30, 2020		December 31, 2019
Unbilled receivables	$	12,955	$	10,467
Receivable from the U.S. government	$	70,106	$	64,819
Contract assets	$	10,086	$	15,631
Contract liabilities	$	8,670	$	11,167

Contract Assets - Contract assets are those of ASUS and consist of unbilled revenues recognized from work-in-progress construction projects, where the right to payment is conditional on something other than the passage of time. The classification of this asset as current or noncurrent is based on the timing of when ASUS expects to bill these amounts.

Contract Liabilities - Contract liabilities are those of ASUS and consist of billings in excess of revenue recognized. The classification of this liability as current or noncurrent is based on the timing of when ASUS expects to recognize revenue.

Revenues for the three and nine months ended September 30, 2020, which were included in contract liabilities at the beginning of the period were $7.1 million and $10.9 million, respectively. Contracted services revenues recognized during the three and nine months ended September 30, 2020 from performance obligations satisfied in previous periods were not material.

As of September 30, 2020, Registrant's aggregate remaining performance obligations, which are entirely for the contracted services segment, were $3.2 billion. Registrant expects to recognize revenue on these remaining performance obligations over the remaining term of each of the 50-year contracts, which range from 34 to 48 years. Each of the contracts with the U.S. government is subject to termination, in whole or in part, prior to the end of its 50-year term for convenience of the U.S. government.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Regulated Operations [Abstract]

Regulatory Matters

In accordance with accounting principles for rate-regulated enterprises, GSWC and BVESI record regulatory assets, which represent probable future recovery of costs from customers through the ratemaking process, and regulatory liabilities, which represent probable future refunds that are to be credited to customers through the ratemaking process. At September 30, 2020, GSWC and BVESI had approximately $44.9 million of regulatory liabilities, net of regulatory assets, not accruing carrying costs. Of this amount, (i) $78.8 million of regulatory liabilities are excess deferred income taxes arising from the lower federal income tax rate due to the Tax Cuts and Jobs Act ("Tax Act") enacted in December 2017 that are expected to be refunded to customers, (ii) $11.5 million of regulatory liabilities are from flowed-through deferred income taxes, (iii) $41.7 million of net regulatory assets relates to the underfunded position in GSWC's pension and other retirement obligations (not including the two-way pension balancing accounts), and (iv) a $2.5 million regulatory asset relates to a memorandum account authorized by the CPUC to track unrealized gains and losses on BVESI's purchase power contracts over the term of the contracts. The remainder of regulatory assets relates to other items that do not provide for or incur carrying costs.

Regulatory assets represent costs incurred by GSWC and BVESI for which either has received or expects to receive rate recovery in the future. In determining the probability of costs being recognized in other periods, GSWC and BVESI consider regulatory rules and decisions, past practices, and other facts or circumstances that would indicate if recovery is probable. If the CPUC determines that a portion of either GSWC’s or BVESI's assets are not recoverable in customer rates, the applicable entity must determine if it has suffered an asset impairment that requires it to write down the asset's value. Regulatory assets are offset against regulatory liabilities within each ratemaking area. Amounts expected to be collected or refunded in the next twelve months have been classified as current assets and current liabilities by ratemaking area. Regulatory assets, less regulatory liabilities, included in the consolidated balance sheets are as follows:


(dollars in thousands)	September 30, 2020		December 31, 2019
GSWC
Water Revenue Adjustment Mechanism and Modified Cost Balancing Account	$	24,904	$	22,535

Regulatory matters are discussed in the consolidated financial statements and the notes thereto included in the Company's Form 10-K for the year ended December 31, 2019 filed with the SEC. The discussion below focuses on significant matters and developments since December 31, 2019.

Alternative-Revenue Programs:

GSWC records the difference between what it bills its water customers and that which is authorized by the CPUC using the Water Revenue Adjustment Mechanism ("WRAM") and the Modified Cost Balancing Account (“MCBA”) accounts approved by the CPUC. The over- or under-collection of the WRAM is aggregated with the MCBA over- or under-collection for the

corresponding ratemaking area and bears interest at the current 90-day commercial paper rate. On August 27, 2020, the CPUC issued a final decision in the first phase of the CPUC’s Order Instituting Rulemaking evaluating the low income ratepayer assistance and affordability objectives contained in the CPUC’s 2010 Water Action Plan, which also addressed other issues including matters associated with the continued use of the WRAM by California water utilities. The final decision also addressed the continued use of the MCBA, which is a full-cost balancing account used to track the difference between adopted and actual water supply costs (including the effects of changes in both rates and volume). Based on the final decision, any general rate case application filed by GSWC and the other California water utilities after the August 27, 2020 effective date of this decision, may not include a proposal to continue the use of the WRAM or MCBA, but may instead include a proposal to use a limited price adjustment mechanism (the Monterey-Style WRAM) and an incremental supply cost balancing account. On or prior to October 5, 2020, GSWC, other California water utilities, and the California Water Association filed separate applications for rehearing on this matter. At this time, management cannot predict the outcome of this matter.

As required by the accounting guidance for alternative revenue programs, GSWC is required to collect its WRAM balances, net of its MCBA, within 24 months following the year in which an under-collection is recorded in order to recognize such amounts as revenue. The recovery periods for the majority of GSWC's WRAM/MCBA balances are primarily within 12 to 24 months. In February 2020, GSWC filed with the CPUC for recovery of the 2019 WRAM/MCBA balances. Accordingly, GSWC implemented surcharges to recover all of its WRAM/MCBA balances as of December 31, 2019. For the three months ended September 30, 2020 and 2019, surcharges (net of surcredits) of approximately $4.4 million and $5.5 million, respectively, were billed to customers to recover previously incurred under-collections in the WRAM/MCBA accounts. For the nine months ended September 30, 2020 and 2019, surcharges (net of surcredits) of approximately $10.5 million and $9.1 million, respectively, were billed to customers to recover previously incurred under-collections in the WRAM/MCBA accounts. During the nine months ended September 30, 2020, GSWC recorded additional net under-collections in the WRAM/MCBA accounts of approximately $12.8 million due to lower-than-adopted water usage, as well as higher-than-adopted supply costs currently in billed customer rates. As of September 30, 2020, GSWC had an aggregated regulatory asset of $24.9 million, which is comprised of a $10.3 million under-collection in the WRAM accounts and a $14.6 million under-collection in the MCBA accounts.

Catastrophic Event Memorandum Account:

The CPUC has approved GSWC's and BVESI's requests to activate a Catastrophic Event Memorandum Account ("CEMA") for the impact of the COVID-19 pandemic. The Company's response to the pandemic has included suspending service disconnections for nonpayment. Costs incurred by GSWC and BVESI in response to the COVID-19 pandemic, including bad debt expense in excess of what is included in their respective revenue requirements, are being included in the CEMA accounts for future recovery. As of September 30, 2020, $1.4 million in COVID-19 related incremental costs have been recorded as regulatory assets as GSWC and BVESI believe their respective costs are probable of recovery.

Cost of Capital Proceeding:

In March 2018, the CPUC issued a final decision in the cost of capital proceeding for GSWC and three other water utilities serving California for the years 2018 – 2020. Among other things, the final decision adopted for GSWC's water segment a return on equity of 8.90%, with a return on rate base of 7.91%.

Investor-owned water utilities serving California are required to file their cost of capital applications on a triennial basis, with the next scheduled filing required to have taken place on May 1, 2020 and to be effective for the years 2021 – 2023. In January 2020, GSWC, along with the three other water utilities, requested an extension of the date by which each of them must file its 2020 cost of capital application. In March 2020, the CPUC approved the request, postponing the filing date by one year until May 1, 2021, with a corresponding effective date of January 1, 2022. GSWC’s current authorized rate of return on rate base of 7.91%, based on its weighted cost of capital, will continue in effect through December 31, 2021.

Earnings per Share/Capital Stock

Earnings Per Share [Abstract]

Earnings per Share/Capital Stock

In accordance with the accounting guidance for participating securities and earnings per share (“EPS”), Registrant uses the “two-class” method of computing EPS. The “two-class” method is an earnings allocation formula that determines EPS for each class of common stock and participating security. AWR has participating securities related to restricted stock units that earn dividend equivalents on an equal basis with AWR’s Common Shares, and that have been issued under AWR's stock incentive plans for employees and the non-employee directors stock plans. 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 used for calculating basic net income per share:


Basic:	For The Three Months Ended September 30,				For The Nine Months Ended September 30,
(in thousands, except per share amounts)	2020		2019		2020		2019
Net income	$	26,530	$	28,006	$	66,214	$	67,642
Less: (a) Distributed earnings to common shareholders	12,356		11,234		34,848		31,466
Distributed earnings to participating securities	43		50		116		137
Undistributed earnings	14,131		16,722		31,250		36,039

(b) Undistributed earnings allocated to common shareholders	14,083		16,647		31,146		35,882
Undistributed earnings allocated to participating securities	48		75		104		157

Total income available to common shareholders, basic (a)+(b)	$	26,439	$	27,881	$	65,994	$	67,348

Weighted average Common Shares outstanding, basic	36,886		36,835		36,877		36,804

Basic earnings per Common Share	$	0.72	$	0.76	$	1.79	$	1.83

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 AWR’s stock incentive plans for employees and the non-employee directors stock plans, and net income. There were no options outstanding as of September 30, 2020 and there were 8,556 options outstanding as of September 30, 2019 under these plans. At September 30, 2020 and 2019, there were also 127,234 and 165,783 restricted stock units outstanding, respectively, including performance shares awarded to officers of the Registrant.

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 September 30,				For The Nine Months Ended September 30,
(in thousands, except per share amounts)	2020		2019		2020		2019
Common shareholders earnings, basic	$	26,439	$	27,881	$	65,994	$	67,348
Undistributed earnings for dilutive stock-based awards	48		75		104		157
Total common shareholders earnings, diluted	$	26,487	$	27,956	$	66,098	$	67,505

Weighted average common shares outstanding, basic	36,886		36,835		36,877		36,804
Stock-based compensation (1)	116		161		113		156
Weighted average common shares outstanding, diluted	37,002		36,996		36,990		36,960

Diluted earnings per Common Share	$	0.72	$	0.76	$	1.79	$	1.83

(1) In applying the treasury stock method of reflecting the dilutive effect of outstanding stock-based compensation in the calculation of diluted EPS, 8,556 stock options at September 30, 2019, respectively, were deemed to be outstanding in accordance with accounting guidance on earnings per share. All of the 127,234 and 165,783 restricted stock units at September 30, 2020 and 2019, respectively, were included in the calculation of diluted EPS for the three months ended September 30, 2020 and 2019.

There were no stock options outstanding at either September 30, 2020 or September 30, 2019 that were anti-dilutive.

During the nine months ended September 30, 2020 and 2019, AWR issued 42,447 and 81,459 common shares related to stock options and restricted stock units, for approximately $30,000 and $416,000, respectively, under Registrant’s stock incentive plans for employees.

During the nine months ended September 30, 2020 and 2019, AWR paid $1.9 million and $1.6 million, respectively, to taxing authorities on employees' behalf for shares withheld related to net share settlements. During the nine months ended September 30, 2020 and 2019, GSWC paid $1.7 million and $1.3 million, respectively, to taxing authorities on employees' behalf for shares withheld related to net share settlements. These payments are included in the stock-based compensation caption of the statements of equity.

During the three months ended September 30, 2020 and 2019, AWR paid quarterly dividends of approximately $12.4 million, or $0.335 per share, and $11.2 million, or $0.305 per share, respectively. During the nine months ended September 30, 2020 and 2019, AWR paid quarterly dividends of approximately $34.8 million, or $0.945 per share, and $31.5 million, or $0.855 per share, respectively.

During the three months ended September 30, 2020 and 2019, GSWC did not pay a dividend to AWR. Instead, ASUS paid dividends of $12.4 million and $12.3 million, respectively, to AWR during these periods. During the nine months ended September 30, 2020 and 2019, GSWC paid dividends of $22.5 million and $20.2 million, respectively, to AWR.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

BVESI purchases power under long-term contracts at a fixed cost depending on the amount of power and the period during which the power is purchased under such contracts. These contracts provide power at a fixed cost over approximately three- and five-year terms depending on the amount of power and period during which the power is purchased under the contracts.

These purchase power contracts are subject to the accounting guidance for derivatives and require mark-to-market derivative accounting. Among other things, the CPUC authorized the use of a regulatory asset and liability memorandum account to offset the mark-to-market entries required by the accounting guidance. Accordingly, all unrealized gains and losses generated from the purchased power contracts are deferred on a monthly basis into a non-interest bearing regulatory memorandum account that tracks the changes in fair value of the derivative throughout the terms of the contracts. As a result, these unrealized gains and losses did not impact Registrant’s earnings. As of September 30, 2020, there was a $2.5 million unrealized loss recorded as a regulatory asset in the memorandum account for the purchased power contracts. The notional volume of derivatives remaining under these long-term contracts as of September 30, 2020 was 528,442 megawatt hours.

The accounting guidance for fair value measurements applies to all financial assets and financial liabilities that are measured and reported on a fair value basis. Under the accounting guidance, BVESI has made fair value measurements that are classified and disclosed in one of the following three categories:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

To value the contracts, Registrant utilizes various inputs that include quoted market prices for energy over the duration of the contracts. 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 that are not observable in or corroborated by the market. When such inputs have a significant impact on the measurement of fair value, the instruments are categorized as Level 3. Accordingly, the valuation of the derivatives on Registrant’s purchased power contract has been classified as Level 3 for all periods presented.

The following table presents changes in the fair value of the Level 3 derivatives for the three and nine months ended September 30, 2020 and 2019:


	For The Three Months Ended September 30,				For The Nine Months Ended September 30,

Fair Value of Financial Instruments

For cash and cash equivalents, accounts receivable, accounts payable and short-term debt, the carrying amount is assumed to approximate fair value due to the short-term nature of these items.

Investments held in a Rabbi Trust for the supplemental executive retirement plan ("SERP") are measured at fair value and totaled $22.8 million as of September 30, 2020. All equity investments in the Rabbi Trust are Level 1 investments in mutual funds. The investments held in the Rabbi Trust are included in "Other Property and Investments" on Registrant's balance sheets.

The table below estimates the fair value of long-term debt held by GSWC. The fair values as of September 30, 2020 and December 31, 2019 were determined using rates for similar financial instruments of the same duration utilizing Level 2 methods and assumptions. Changes in the assumptions will produce different results.

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes AWR's effective income tax rate (“ETR”) was 25.4% and 25.1% for the three months ended September 30, 2020 and 2019, respectively, and was 24.3% and 23.3% for the nine months ended September 30, 2020 and 2019, respectively. GSWC's ETR was 26.7% and 26.4% for the three months ended September 30, 2020 and 2019, respectively, and was 25.5% and 24.1% for the nine months ended September 30, 2020 and 2019, respectively. The AWR and GSWC effective tax rates differ from the federal statutory tax rate primarily due to (i) state taxes; (ii) permanent differences, including the excess tax benefits from share-based payments, which were reflected in the income statements and resulted in a reduction to income tax expense during the three and nine months ended September 30, 2020 and 2019; (iii) the continuing amortization of the excess deferred income tax liability that commenced upon the lowering of the federal tax rate; and (iv) differences between book and taxable income that are treated as flow-through adjustments in accordance with regulatory requirements (principally from plant, rate-case, and compensation expenses). As a regulated utility, GSWC treats certain temporary differences as flow-through in computing its income tax expense consistent with the income tax method used in its CPUC-jurisdiction ratemaking. Flow-through items either increase or decrease tax expense and thus impact the ETR.

During the nine months ended September 30, 2020, Registrant contributed approximately $3.7 million to its pension plan.

As authorized by the CPUC in the water and electric general rate case decisions, GSWC and BVESI utilize two-way balancing accounts for each of their ratemaking areas, as applicable, to track differences between the forecasted annual pension expenses in rates, or expected to be in rates, and the actual annual expense recorded in accordance with the accounting guidance for pension costs. During the three and nine months ended September 30, 2020, GSWC's actual pension expense was higher than the amounts included in water customer rates by $121,000 and $362,000, respectively. During the three and nine ended September 30, 2019, GSWC's actual pension expense was higher than the amounts included in water customer rates by $160,000 and $502,000, respectively. BVESI's actual expense was lower than the amounts included in electric customer rates for all periods presented. As of September 30, 2020, GSWC and BVESI had net over-collections in the two-way pension balancing accounts of $1.1 million and $166,000, respectively, included as part of the regulatory assets and liabilities (Note 3).

Contingencies	9 Months Ended
Contingencies	Sep. 30, 2020
Loss Contingencies [Line Items]
Contingencies	Contingencies Environmental Clean-Up and Remediation: GSWC has been involved in environmental remediation and cleanup at a plant site ("Chadron Plant") that contained an underground storage tank which was used to store gasoline for its vehicles. This tank was removed from the ground in July 1990 along with the dispenser and ancillary piping. Since then, GSWC has been involved in various remediation activities at this site. Analysis indicates that off-site monitoring wells may be necessary to document effectiveness of remediation. As of September 30, 2020, the total amount spent to clean up and remediate GSWC’s plant facility was approximately $6.3 million, of which $1.5 million has been paid by the State of California Underground Storage Tank Fund. Amounts paid by GSWC have been included in rate base and approved by the CPUC for recovery. As of September 30, 2020, GSWC has a regulatory asset and an accrued liability for the estimated additional cost of $1.3 million to complete the cleanup at the site. The estimate includes costs for two years of continued activities of groundwater cleanup and monitoring, future soil treatment and site-closure-related activities. The ultimate cost may vary as there are many unknowns in remediation of underground gasoline spills and this is an estimate based on currently available information. Management also believes it is probable that the estimated additional costs will be approved in rate base by the CPUC. Other Litigation: Registrant is also subject to other ordinary routine litigation incidental to its business, some of which may include claims for compensatory and punitive damages. Management believes that rate recovery, proper insurance coverage and reserves are in place to insure against, among other things, property, general liability, employment, and workers’ compensation claims incurred in the ordinary course of business. Insurance coverage may not cover certain claims involving punitive damages; however, Registrant does not believe the outcome from any pending suits or administrative proceedings will have a material effect on Registrant's consolidated results of operations, financial position, or cash flows.

Allowance for Doubtful Accounts [Abstract]

Allowance for Doubtful Accounts

Note 10 — Allowance for Doubtful Accounts

Registrant adopted ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, effective January 1, 2020. The guidance requires estimated credit losses on financial instruments, such as Registrant's trade and other receivables, be based on expected credit losses rather than incurred losses.

Registrant's allowance for doubtful accounts as of September 30, 2020 was developed based on the observed effects of the economic impact from the COVID-19 pandemic on GSWC's and BVESI's aging of utility customer accounts receivable, as well as economic data such as unemployment rates and other considerations that may impact customers' ability to pay their bills. Management also took into consideration the impact of the CPUC's order to suspend, through April 2021, service disconnections for nonpayment, which is expected to have the effect of increasing delinquent customer accounts receivable during the COVID-19 pandemic. However, the CPUC has authorized GSWC and BVESI to track incremental costs, including bad debt expense in excess of what is included in their respective revenue requirements, incurred as a result of the COVID-19 pandemic in CEMA accounts to be filed with the CPUC for future recovery. Other accounts receivable consist primarily of amounts due from third parties (non-utility customers) for various reasons, including amounts due from contractors, amounts due under settlement agreements, and amounts due from other third-party prime government contractors pursuant to agreements for construction of water and/or wastewater facilities for such third-party prime contractors. Thus far, the COVID-19 pandemic has not materially impacted the collectability of these other accounts receivable.

The table below presents Registrant’s provision for doubtful accounts charged to expense and accounts written off, net of recoveries.

Segment Reporting [Abstract]

Business Segments

AWR has three reportable segments: water, electric and contracted services. Prior to July 1, 2020, GSWC had two segments, water and electric. On July 1, 2020, GSWC completed the transfer of the electric utility assets and liabilities from its electric division to BVESI, a separate legal entity and now a wholly owned subsidiary of AWR. On a stand-alone basis, AWR has no material assets other than its equity investments in its subsidiaries and note receivables therefrom, and deferred taxes.

All activities of GSWC and BVESI are geographically located within California. Activities of ASUS and its subsidiaries are conducted in California, Florida, Georgia, Kansas, Maryland, New Mexico, North Carolina, South Carolina, Texas and Virginia. Each of ASUS’s wholly owned subsidiaries is regulated, if applicable, by the state in which the subsidiary primarily conducts water and/or wastewater operations. Fees charged for operations and maintenance and renewal and replacement services are based upon the terms of the contracts with the U.S. government, which have been filed, as appropriate, with the commissions in the states in which ASUS’s subsidiaries are incorporated.

The tables below set forth information relating to AWR’s operating segments and AWR Parent. Total assets by segment are not presented below, as certain of Registrant’s assets are not tracked by segment. The utility plant amounts are net of respective accumulated provisions for depreciation. Capital additions reflect capital expenditures paid in cash, excluding U.S. government- and third-party contractor-funded capital expenditures for ASUS and property installed by developers and conveyed to GSWC or BVESI.

Completion of Electric Utility Reorganization Plan

9 Months Ended

Sep. 30, 2020

Restructuring and Related Activities [Abstract]

Completion of Electric Utility Reorganization Plan

On July 1, 2020, GSWC completed the transfer of approximately $71.3 million in net assets and equity (based on their recorded amounts) from its electric utility division to BVESI in exchange for common shares of BVESI of equal value. This was a non-cash transaction, and no gain or loss was recognized. GSWC then immediately distributed all of BVESI's common shares to AWR, whereupon BVESI became wholly owned directly by AWR. The reorganization is not expected to result in any substantive changes to AWR's operations or business segments. In addition, pursuant to federal and state tax law, the exchange and distribution qualify as a tax-free reorganization; consequently, no income tax liability was triggered for the AWR consolidated group or any of its members.

The transfer between GSWC and BVESI, both wholly owned subsidiaries of AWR, is considered a common control transaction. Although the electric utility division was considered a separate business segment and component of GSWC, the transfer did not qualify as a discontinued operation based on management's assessment of the applicable accounting guidance. As a result of this transfer, from July 1, 2020 onward, operating results and cash flows of the electric segment, as well as its assets and liabilities, are no longer included in GSWC's financial statements, but continue to be included in AWR's consolidated financial statements. GSWC's statement of income for the nine months ended September 30, 2020 includes the electric segment's results through June 30, 2020.

The table below sets forth selected information relating to the electric segment's results of operations for the three months ended September 30, 2020 and 2019, and its cash flows for the three months ended September 30, 2020 (in thousands):

(1) Operating income for the three months ended September 30, 2019 included the retroactive impact of the CPUC's August 2019 final decision on the electric general rate case, which totaled approximately $3.7 million for periods prior to the third quarter of 2019.

(2) Effective July 1, 2020, BVESI entered into a 3-year, $35 million revolving credit facility agreement with a bank and began borrowing under this facility. As of September 30, 2020, there was $3.0 million outstanding under the new facility. Under the terms of the credit agreement, BVESI has the option to request an increase in the facility by an additional $15 million.

Summary of Significant Accounting Policies: (Policies)	9 Months Ended
Summary of Significant Accounting Policies: (Policies)	Sep. 30, 2020
Accounting Policies [Abstract]
Basis of Accounting, Policy	Nature of Operations: American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”), Bear Valley Electric Service, Inc. ("BVESI"), and American States Utility Services, Inc. (“ASUS”) (and its subsidiaries, Fort Bliss Water Services Company (“FBWS”), Terrapin Utility Services, Inc. (“TUS”), Old Dominion Utility Services, Inc. (“ODUS”), Palmetto State Utility Services, Inc. (“PSUS”), Old North Utility Services, Inc. (“ONUS”), Emerald Coast Utility Services, Inc. ("ECUS"), and Fort Riley Utility Services, Inc. ("FRUS")). The subsidiaries of ASUS are collectively referred to as the “Military Utility Privatization Subsidiaries.” On July 1, 2020, GSWC completed the transfer of the electric utility assets and liabilities from its electric division to BVESI, a separate legal entity and wholly owned subsidiary of AWR (Note 12). This reorganization is not expected to result in any substantive changes to AWR's operations and business segments. AWR, through its wholly owned subsidiaries, serves over one million people in nine states. GSWC and BVESI are both California public utilities, with GSWC engaged in the purchase, production, distribution and sale of water throughout California serving approximately 261,500 customer connections, while BVESI distributes electricity in several San Bernardino County mountain communities in California serving approximately 24,500 customer connections. The California Public Utilities Commission (“CPUC”) regulates GSWC’s and BVESI's businesses in matters including properties, rates, services, facilities, and transactions between GSWC, BVESI, and their affiliates. ASUS, through its wholly owned subsidiaries, operates, maintains and performs construction activities (including renewal and replacement capital work) on water and/or wastewater systems at various U.S. military bases pursuant to initial 50-year firm fixed-price contracts. These contracts are subject to annual economic price adjustments and modifications for changes in circumstances, changes in laws and regulations and additions to the contract value for new construction of facilities at the military bases. There is no direct regulatory oversight by the CPUC over AWR or the operations, rates or services provided by ASUS or any of its wholly owned subsidiaries. Basis of Presentation: The consolidated financial statements and notes thereto are presented in a combined report filed by two separate Registrants: AWR and GSWC. References in this report to “Registrant” are to AWR and GSWC, collectively, unless otherwise specified. Certain prior period amounts have been reclassified on the statements of cash flows to conform to current year presentation. AWR owns all of the outstanding common shares of GSWC, BVESI, and ASUS. ASUS owns all of the outstanding common stock of the Military Utility Privatization Subsidiaries. The consolidated financial statements of AWR include the accounts of AWR and its subsidiaries. These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). Intercompany 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”). The December 31, 2019 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. 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 revenues and expenses during the reporting period. Actual results could differ from these 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, 2019 filed with the SEC.
GSWC's Related Party Transactions and Financing Activities	Related Party Transactions and Financing Activities: GSWC, BVESI, and ASUS provide and/or receive various support services to and from their parent, AWR, and among themselves. GSWC has also allocated certain corporate office administrative and general costs to its affiliates, BVESI and ASUS, using allocation factors approved by the CPUC. GSWC allocated corporate office administrative and general costs to BVESI of approximately $643,000 during the three months ended September 30, 2020. GSWC allocated corporate office administrative and general costs to ASUS of approximately $1.2 million during each of the three months ended September 30, 2020 and 2019, and approximately $3.8 million and $3.5 million during the nine months ended September 30, 2020 and 2019 respectively. AWR borrows under a credit facility, which expires in May 2023, and provides funds to GSWC and ASUS in support of their operations. The interest rate charged to GSWC and ASUS is sufficient to cover AWR’s interest expense under the credit facility. In March 2020, AWR amended the credit facility to temporarily increase the borrowing capacity by $35.0 million to $260.0 million until December 31, 2020, at which point the commitment will be reduced to $200.0 million. As of September 30, 2020, there was $89.0 million outstanding under this facility. Effective July 1, 2020, BVESI put in place and has access to a 3-year, $35 million revolving credit facility. Under the terms of the credit agreement, BVESI has the option to request an increase in the facility by an additional $15 million. As of September 30, 2020, there was $3.0 million outstanding under this facility. On July 8, 2020, GSWC completed the issuance of unsecured private placement notes totaling $160.0 million. In connection with this financing, GSWC issued (i) $85.0 million aggregate principal amount of Series A Senior Notes at a coupon rate of 2.17% due July 8, 2030, and (ii) $75.0 million aggregate principal amount of Series B Senior Notes at a coupon rate of 2.90% due July 8, 2040. Interest on the Notes is payable semiannually. The Notes are unsecured and rank equally with GSWC’s unsecured and unsubordinated debt. GSWC may, at its option, redeem all or portions of the Notes at any time upon written notice, subject to payment of a make-whole premium based on 50 basis points above the applicable treasury yield. Under the terms of the Notes, GSWC may not incur any additional indebtedness or pay any distributions to its parent, AWR, if after giving effect thereto, GSWC would have a total indebtedness to capitalization ratio of more than 0.6667:1.00. In addition, GSWC may not incur any additional indebtedness if, after giving effect thereto, it would have a total indebtedness to earnings before interest, taxes, depreciation and amortization ratio greater than 8.00:1.00. GSWC used the proceeds from the new notes to pay down a majority of the intercompany borrowings from AWR parent. AWR used the proceeds received from GSWC to pay down borrowings on its revolving credit facility. Following the issuance of the notes and effective July 15, 2020, AWR reduced the aggregate borrowing capacity of its credit facility to $200.0 million pursuant to the terms of that credit facility agreement. The CPUC requires GSWC to completely pay down all intercompany borrowings from AWR within a 24-month period. The next 24-month period in which GSWC is required to completely pay down its intercompany borrowings ends in November 2020. As a result, GSWC’s intercompany borrowings of $34.1 million as of September 30, 2020 have been classified as a current liability on GSWC’s balance sheet.
COVID-19 Impact	COVID-19 Impact: GSWC, BVESI, and ASUS have continued their operations given that their water, wastewater, and electric utility services are deemed essential. The Company's responses take into account the guidance provided by federal, state, and local health authorities and other government officials to the COVID-19 pandemic. Some of the actions taken by GSWC and BVESI include: (i) suspending, at least through April 2021, service disconnections for nonpayment pursuant to CPUC orders; (ii) increasing the number of employees telecommuting; and (iii) delaying some capital improvement projects at the water utility services business. Thus far, the COVID-19 pandemic has not had a material impact on ASUS's operations. The pandemic has caused significant volatility on financial markets, resulting in significant fluctuations in the fair value of plan assets in GSWC's pension and other retirement plans. Management believes this volatility may continue throughout the pandemic. Due to expected future credit losses on utility customer bills, Registrant has increased its allowance for doubtful accounts as of September 30, 2020. However, the CPUC has authorized GSWC and BVESI to track incremental costs, including bad debt expense in excess of what is included in their respective revenue requirements, incurred as a result of the COVID-19 pandemic in a Catastrophic Event Memorandum Account ("CEMA") to be filed with the CPUC for future recovery. GSWC and BVESI have recorded a total of approximately $1.4 million in the CEMA accounts as regulatory assets, as the Company believes such amounts are probable of recovery.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements: Accounting Pronouncements Adopted in 2020 In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and issued further guidance in November 2018 and May 2019 related to the impairment of financial instruments, effective January 1, 2020. The new guidance provides an impairment model, known as the current expected credit loss model, which is based on expected credit losses rather than incurred losses over the remaining life of most financial assets measured at amortized cost, including trade and other receivables. For the three and nine months ended September 30, 2020, Registrant has increased its allowance for doubtful accounts for utility customer accounts receivable by $871,000 and $1.9 million, respectively, due to Registrant's current estimate of the expected associated economic impact of the COVID pandemic (see Note 10). Accounting Pronouncements to be Adopted in Future Periods In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits—Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU removes disclosures to pension plans and other retirement plans that no longer are considered cost beneficial, clarifies the specific disclosure requirements and adds disclosure requirements deemed relevant. This ASU is effective for fiscal years ending after December 15, 2020 and will be applied by Registrant on a retrospective basis to all periods presented. Registrant does not believe the ASU will have a material impact on the Company's financial statements and disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740)—Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for income taxes by removing certain exceptions and clarifying certain requirements regarding franchise taxes, goodwill, consolidated tax expenses, and annual effective tax rate calculations. The ASU is effective for fiscal years beginning after December 15, 2020. Early adoption is permitted. Registrant does not believe this ASU will have a material impact on its financial statements.
