Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1: Basis of Presentation The unaudited Consolidated Financial Statements included in this report include the accounts of American Water Works Company, Inc. and all of its subsidiaries (the “Company” or “American Water”), in which a controlling interest is maintained after the elimination of intercompany balances and transactions. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting, and the rules and regulations for reporting on Quarterly Reports on Form 10-Q (“Form 10-Q”). Accordingly, they do not contain certain information and disclosures required by GAAP for comprehensive financial statements. In the opinion of management, all adjustments necessary for a fair statement of the financial position as of September 30, 2023, and the results of operations and cash flows for all periods presented, have been made. All adjustments are of a normal, recurring nature, except as otherwise disclosed. The unaudited Consolidated Financial Statements and Notes included in this report should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (“Form 10-K”), which provides a more complete discussion of the Company’s accounting policies, financial position, operating results and other matters. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year, primarily due to the seasonality of the Company’s operations.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Significant Accounting Policies	Note 2: Significant Accounting Policies New Accounting Standards Presented in the table below are new accounting standards that were adopted by the Company in 2023: Standard Description Date of Adoption Application Effect on the Consolidated Financial Statements Accounting for Contract Assets and Contract Liabilities from Contracts with Customers The guidance requires an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification Topic 606, as if it had originated the contracts. The amendments in this update also provide certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. January 1, 2023 Prospective This standard did not have a material impact on the Consolidated Financial Statements Troubled Debt Restructurings and Vintage Disclosures The main provisions of this standard eliminate the receivables accounting guidance for troubled debt restructurings (“TDRs”) by creditors while enhancing disclosure requirements when a borrower is experiencing financial difficulty. Entities must apply the loan refinancing and restructuring guidance for receivables to determine whether a modification results in a new loan or a continuation of an existing loan. Additionally, the amendments in this update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases. January 1, 2023 Prospective, with a modified retrospective option for amendments related to the recognition and measurement of TDRs. This standard did not have a material impact on the Consolidated Financial Statements Presentation and Disclosure Requirements The guidance amends GAAP disclosure and presentation requirements for various subtopics in the Financial Accounting Standards Board Codification and was issued in response to the U.S. Securities and Exchange Commission’s (“SEC”) final rule published in August 2018 that updated and simplified disclosure requirements that it believed were outdated, superseded, overlapping, duplicative and redundant. The new guidance is intended to align GAAP requirements with those of the SEC for all entities. The date on which the SEC’s removal of the related disclosure requirement became effective Prospective This standard did not have a material impact on the Consolidated Financial Statements Property, Plant and Equipment The New Jersey Economic Development Authority (“NJEDA”) determined that the Company was qualified to receive $161 million in tax credits in connection with its capital investment in its corporate headquarters in Camden, New Jersey. The Company was qualified to receive the tax credits over a 10-year period commencing in 2019. In March 2023, the NJEDA issued the utilization certificate for the 2020 tax credits to the Company in the amount of $16 million. The Company sold these tax credits to external parties in March 2023 for $15 million. As of September 30, 2023 and December 31, 2022, the Company had $32 million and $48 million, respectively, in Other current assets and $97 million in Other long-term assets on the Consolidated Balance Sheets as a result of these tax credits. The Company has made the necessary annual filing for the years ended December 31, 2021 and 2022. Allowance for Uncollectible Accounts Allowances for uncollectible accounts are maintained for estimated probable losses resulting from the Company’s inability to collect receivables from customers. Accounts that are outstanding longer than the payment terms are considered past due. A number of factors are considered in determining the allowance for uncollectible accounts, including the length of time receivables are past due, previous loss history, current economic and societal conditions and reasonable and supportable forecasts that affect the collectability of receivables from customers. The Company generally writes off accounts when they become uncollectible or are over a certain number of days outstanding. Presented in the table below are the changes in the allowance for uncollectible accounts for the nine months ended September 30: 2023 2022 Balance as of January 1 $ (60) $ (75) Amounts charged to expense (17) (17) Amounts written off 20 19 Other, net (a) 4 9 Balance as of September 30 $ (53) $ (64) (a) This portion of the allowance for uncollectible accounts is primarily related to COVID-19 related regulatory asset activity. Reclassifications Certain reclassifications have been made to prior periods in the Consolidated Financial Statements and Notes to conform to the current presentation.

The Virginia State Corporation Commission issued its final Order on April 24, 2023. On June 29, 2023, the California Public Utilities Commission (“CPUC”) issued a decision on the cost of capital application for the Company’s California subsidiary, which authorizes a return on equity of 8.98% and a capital structure with an equity component of 57.04% for the three-year period from 2022 to 2024. The CPUC’s decision is not retroactive and was effective from the date of the order through the end of 2024. The decision includes a Water Cost of Capital Mechanism (the “WCCM”) that would allow the California subsidiary to increase its return on equity for the remainder of 2023 and 2024 based on capital market rates. As authorized by the WCCM, on June 30, 2023, the California subsidiary filed with the CPUC staff an advice letter to seek a 52 basis point increase to the return on equity for 2023, which was approved on July 25, 2023, increasing the return on equity to 9.50%, effective July 31, 2023. On October 16, 2023, the California subsidiary filed with the CPUC staff an advice letter to implement a 70 basis point increase to the return on equity, effective January 1, 2024, based on the triggering of the WCCM. After approval, the authorized return on equity will increase to 10.20%. On May 3, 2023, the Missouri Public Service Commission issued an order approving the March 3, 2023, joint settlement agreement in the general rate case filed on July 1, 2022, by the Company’s Missouri subsidiary. The general rate case order approved a $44 million annualized increase in water and wastewater revenues, excluding $51 million in previously approved infrastructure surcharges, and authorized implementation of the new water and wastewater rates effective May 28, 2023. The annualized revenue increase is driven primarily by significant incremental capital investments since the Missouri subsidiary’s 2021 rate case order. The Missouri subsidiary’s view of its rate base is $2.3 billion, and its view as to its return on equity and long-term debt ratio (each of which is based on the general rate case order but was not disclosed therein) is 9.75% and 50.0%, respectively. On April 24, 2023, the Virginia State Corporation Commission issued an order approving the settlement of the rate case filed on September 26, 2022, by the Company’s Virginia subsidiary. The general rate case order approved an $11 million annualized increase in water and wastewater revenues. Interim rates in this proceeding were effective on May 1, 2022, and the order required that the difference between interim and the final approved rates were subject to refund within 90 days of the order issuance. The order approves the settlement terms with a return on equity of 9.7% and a common equity ratio of 40.7%. The annualized revenue increase is driven primarily by significant incremental capital investments since the Virginia subsidiary’s 2020 rate case order that have been completed or were planned through April 30, 2023, increases in pension and other postretirement benefits expense and increases in production costs, including chemicals, fuel and power costs. The general rate case order includes recovery of the Virginia subsidiary’s COVID-19 deferral balance. It also includes approval of the accounting deferral of deviations in pension and other postretirement benefits expense from those established in base rates, until the Virginia subsidiary’s next base rate case. On December 8, 2022, the Pennsylvania Public Utility Commission issued an order approving the joint settlement agreement in the rate case filed on April 29, 2022, by the Company’s Pennsylvania subsidiary. The general rate case order approved a $138 million annualized increase in water and wastewater revenues, excluding $24 million for previously approved infrastructure filings, and authorizes implementation of the new water and wastewater rates effective January 28, 2023. The annualized revenue increase is driven primarily by significant incremental capital investments since the Pennsylvania subsidiary’s 2021 rate case order that will be completed through December 31, 2023, increases in pension and other postretirement benefits expense and increases in production costs, including chemicals, fuel and power costs. The general rate case order also includes recovery of the Pennsylvania subsidiary’s COVID-19 deferral balance. The Pennsylvania subsidiary’s view of its rate base is $5.1 billion, and its view as to its return on equity and long-term debt ratio (each of which is based on the general rate case order but was not disclosed therein) is 10.0% and 44.8%, respectively. On December 15, 2022, the Illinois Commerce Commission issued an order approving the adjustment of base rates requested in a rate case filed on February 10, 2022, by the Company’s Illinois subsidiary. As updated in the Illinois subsidiary’s June 29, 2022 rebuttal filing, the request sought $83 million in additional annualized revenues, excluding previously recovered infrastructure surcharges. The general rate case order approved a $67 million annualized increase in water and wastewater system revenues, excluding previously recovered infrastructure surcharges of $18 million, effective January 1, 2023, based on an authorized return on equity of 9.78%, authorized rate base of $1.64 billion, a common equity ratio of 49.0% and a debt ratio of 51.0%. The annualized revenue increase is being driven primarily by significant water and wastewater system capital investments since the Illinois subsidiary’s 2017 rate case order that have been completed or are planned through December 31, 2023, expected higher pension and other postretirement benefit costs, and increases in production costs, including chemicals, fuel and power costs. Pending General Rate Case Filings On November 1, 2023, the Company’s Virginia subsidiary filed a general rate case requesting $20 million in additional annualized revenues. Interim rates will be effective May 1, 2024, with the difference between interim and final approved rates subject to refund. On June 30, 2023, the Company’s Kentucky subsidiary filed a general rate case requesting $26 million in additional annualized revenues, excluding infrastructure surcharges of $10 million. An order is expected in the general rate case by the end of the first quarter of 2024. On May 1, 2023, the Company’s West Virginia subsidiary filed a general rate case requesting $45 million in additional annualized revenues, excluding previously approved infrastructure surcharges of $7 million. The general rate case includes a future test year capturing planned investment through 2025 and an order is expected to be issued by February 25, 2024. On June 30, 2023, the West Virginia subsidiary filed its annual infrastructure surcharge requesting $8 million in additional annualized revenues for planned investment through 2024. The infrastructure surcharge will be aligned with the investments recognized in the general rate case if the future test year is approved. On March 31, 2023, the Company’s Indiana subsidiary filed a general rate case requesting $87 million in additional annualized revenues, excluding $41 million of revenue from infrastructure filings already approved, which includes three step increases, with $43 million of the increase to be included in rates in January 2024, $18 million in May 2024, and $26 million in May 2025. Hearings were completed in September and an order is expected in the general rate case by the end of January 2024. On July 1, 2022, the Company’s California subsidiary filed a general rate case requesting an increase in 2024 revenue of $56 million and a total increase in revenue over the 2024 to 2026 period of $95 million, all as compared to 2022 revenues. The Company updated its filing in January 2023 to capture the authorized step increase effective January 1, 2023. The filing was also updated to incorporate a decoupling proposal and a revision to the Company’s sales and associated variable expense forecast. The revised filing requested additional annualized revenues for the test year 2024 of $37 million, compared to 2023 revenues. This excludes the proposed step rate and attrition rate increase for 2025 and 2026 of $20 million and $19 million, respectively. The total revenue requirement request for the three-year rate case cycle, incorporating updates to present rate revenues and forecasted demand, is $76 million. In October 2023, evidentiary hearings were held, and an order is expected in the general rate case in 2024 with rates retroactive to January 1, 2024. Infrastructure Surcharges A number of states have authorized the use of regulatory mechanisms that permit rates to be adjusted outside of a general rate case for certain costs and investments, such as infrastructure surcharge mechanisms that permit recovery of capital investments to replace aging infrastructure. Presented in the table below are annualized incremental revenues, assuming a constant water sales volume and customer count, resulting from infrastructure surcharge authorizations that became effective during 2023: (In millions) Effective Date Amount Infrastructure surcharges by state: New Jersey (a) $ 32 Kentucky October 1, 2023 4 Indiana (b) 26 Missouri January 16, 2023 14 Pennsylvania January 1, 2023 3 West Virginia January 1, 2023 7 Total infrastructure surcharge authorizations $ 86 (a) In 2023, $15 million was effective October 30, $1 million was effective June 29 and $16 million was effective April 29. (b) In 2023, $20 million was effective March 23 and $6 million was effective March 8. Pending Infrastructure Surcharge Filings On September 1, 2023, the Company’s Missouri subsidiary filed an infrastructure surcharge proceeding requesting $23 million in additional annualized revenues. Other Regulatory Matters In September 2020, the CPUC released a decision under its Low-Income Rate Payer Assistance program rulemaking that required the Company’s California subsidiary to file a proposal to alter its water revenue adjustment mechanism in its next general rate case filing in 2022, which would have become effective upon receiving an order in the current pending rate case. On October 5, 2020, the Company’s California subsidiary filed an application for rehearing of the decision and following the CPUC’s denial of its rehearing application in September 2021, the Company’s California subsidiary filed a petition for writ of review with the California Supreme Court on October 27, 2021. On May 18, 2022, the California Supreme Court issued a writ of review for the California subsidiary’s petition and the petitions filed by other entities challenging the decision. Independent of the judicial challenge, California passed Senate Bill 1469, which allows the CPUC to consider and authorize the implementation of a mechanism that separates the water corporation’s revenue and its water sales. Legislation was signed by the Governor on September 30, 2022, and became effective on January 1, 2023. In response to the legislation, on January 27, 2023, the Company’s California subsidiary filed an updated application requesting the CPUC to consider a Water Resources Sustainability Plan decoupling mechanism in its pending 2022 general rate case, which will become effective upon receiving an order in the current pending rate case.

Contract Balances Contract assets and contract liabilities are the result of timing differences between revenue recognition, billings, and cash collections. In the Company’s Military Services Group (“MSG”), certain contracts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Contract assets are recorded when billing occurs subsequent to revenue recognition and are reclassified to accounts receivable when billed and the right to consideration becomes unconditional. Contract liabilities are recorded when the Company receives advances from customers prior to satisfying contractual performance obligations, particularly for construction contracts, and are recognized as revenue when the associated performance obligations are satisfied. Contract assets of $112 million and $86 million are included in unbilled revenues on the Consolidated Balance Sheets as of September 30, 2023 and December 31, 2022, respectively. Contract liabilities of $65 million and $91 million are included in other current liabilities on the Consolidated Balance Sheets as of September 30, 2023 and December 31, 2022, respectively. Revenues recognized for the nine months ended September 30, 2023 and 2022, from amounts included in contract liabilities were $92 million and $94 million, respectively. Remaining Performance Obligations Remaining performance obligations (“RPOs”) represent revenues the Company expects to recognize in the future from contracts that are in progress. The Company enters into agreements for the provision of services to water and wastewater facilities for the U.S. military, municipalities and other customers. As of September 30, 2023, the Company’s operation and maintenance (“O&M”) and capital improvement contracts in the MSG and the Contract Services Group have RPOs. Contracts with the U.S. government for work on various military installations expire between 2051 and 2073 and have RPOs of $7.0 billion as of September 30, 2023, as measured by estimated remaining contract revenue. Such contracts are subject to customary termination provisions held by the U.S. government, prior to the agreed-upon contract expiration. Contracts with municipalities and commercial customers expire between 2026 and 2038 and have RPOs of $554 million as of September 30, 2023, as measured by estimated remaining contract revenue. Some of the Company’s long-term contracts to operate and maintain the federal government’s, a municipality’s or other party’s water or wastewater treatment and delivery facilities include responsibility for certain maintenance for some of those facilities, in exchange for an annual fee. Unless specifically required to perform certain maintenance activities, the maintenance costs are recognized when the maintenance is performed.

Equity [Abstract]
Shareholders' Equity	Note 6: Shareholders’ Equity Common Stock Offering On March 3, 2023, the Company completed an underwritten public offering of an aggregate of 12,650,000 shares of parent company common stock. Upon closing of this offering, the Company received, after deduction of the underwriting discount and before deduction of offering expenses, net proceeds of approximately $1,688 million. The Company used the net proceeds of the offering to repay short-term commercial paper obligations of American Water Capital Corp.

Accumulated Other Comprehensive Loss Presented in the table below are the changes in accumulated other comprehensive loss by component, net of tax, for the nine months ended September 30, 2023 and 2022, respectively: Defined Benefit Pension Plans Loss on Cash Flow Hedges Accumulated Other Comprehensive Loss Employee Benefit Plan Funded Status Amortization of Prior Service Cost Amortization of Actuarial Loss Balance as of December 31, 2022 $ (93) $ 1 $ 70 $ (1) $ (23) Other comprehensive income before reclassifications — — — — — Amounts reclassified from accumulated other comprehensive loss — — 1 — 1 Net other comprehensive income — — 1 — 1 Balance as of September 30, 2023 $ (93) $ 1 $ 71 $ (1) $ (22) Balance as of December 31, 2021 $ (107) $ 1 $ 67 $ (6) $ (45) Other comprehensive income before reclassifications — — — 4 4 Amounts reclassified from accumulated other comprehensive income — — 2 — 2 Net other comprehensive income — — 2 4 6 Balance as of September 30, 2022 $ (107) $ 1 $ 69 $ (2) $ (39) The Company does not reclassify the amortization of defined benefit pension cost components from accumulated other comprehensive loss directly to net income in its entirety, as a portion of these costs have been deferred as a regulatory asset. These accumulated other comprehensive loss components are included in the computation of net periodic pension cost. The amortization of the gain (loss) on cash flow hedges is reclassified to net income during the period incurred and is included in interest, net in the accompanying Consolidated Statements of Operations. An unrealized gain (loss) on available-for-sale fixed-income securities is reclassified to net income upon sale of the securities as a realized gain or loss and is included in Other, net in the accompanying Consolidated Statements of Operations.

Long-Term Debt	Sep. 30, 2023
Debt Disclosure [Abstract]
Long-Term Debt	Note 7: Long-Term Debt On June 29, 2023, AWCC issued $1,035 million aggregate principal amount of 3.625% Exchangeable Senior Notes due 2026 (the “Notes”). AWCC received net proceeds of approximately $1,022 million, after deduction of underwriting discounts and commissions but before deduction of offering expenses payable by AWCC. A portion of the net proceeds was used to repay AWCC’s commercial paper obligations and the remainder is being used for general corporate purposes. The Notes are senior unsecured obligations of AWCC and have the benefit of a support agreement from parent company, which serves as the functional equivalent of a guarantee by parent company of the obligations of AWCC under the Notes. The Notes will mature on June 15, 2026 (the “Maturity Date”), unless earlier exchanged or repurchased. The Notes are exchangeable at an initial exchange rate of 5.8213 shares of parent company's common stock per $1,000 principal amount of Notes (equivalent to an initial exchange price of approximately $171.78 per share of common stock). The initial exchange rate of the Notes is subject to adjustment as provided in the indenture pursuant to which the Notes were issued (the “Note Indenture”). Prior to the close of business on the business day immediately preceding March 15, 2026, the Notes are exchangeable at the option of the noteholders only upon the satisfaction of specified conditions and during certain periods described in the Note Indenture. On or after March 15, 2026, until the close of business on the business day immediately preceding the Maturity Date, the Notes will be exchangeable at the option of the noteholders at any time regardless of these conditions or periods. Upon any exchange of the Notes, AWCC will (1) pay cash up to the aggregate principal amount of the Notes and (2) pay or deliver (or cause to be delivered), as the case may be, cash, shares of parent company's common stock, or a combination of cash and shares of such common stock, at AWCC's election, in respect of the remainder, if any, of AWCC’s exchange obligation in excess of the aggregate principal amount of the Notes being exchanged. AWCC may not redeem the Notes prior to the Maturity Date, and no sinking fund is provided for the Notes. Subject to certain conditions, holders of the Notes will have the right to require AWCC to repurchase all or a portion of their Notes upon the occurrence of a fundamental change, as defined in the Note Indenture, at a repurchase price of 100% of their principal amount plus any accrued and unpaid interest. In addition to the Notes issued by AWCC as described above, during the nine months ended September 30, 2023, AWCC and the Company’s regulated subsidiaries issued in the aggregate $211 million of private activity bonds and government funded debt in multiple transactions, with annual interest rates ranging from 0.00% to 3.88%, a weighted average interest rate of 3.50%, and maturity dates ranging from 2025 to 2041. During the nine months ended September 30, 2023, $125 million of the $211 million of private activity bonds and government funded debt issued by AWCC and the Company's regulated subsidiaries were collateralized. During the nine months ended September 30, 2023, AWCC and the Company’s regulated subsidiaries made sinking fund payments for, or repaid at maturity, $263 million in aggregate principal amount of outstanding long-term debt, with annual interest rates ranging from 0.00% to 6.55%, a weighted average interest rate of 1.64%, and maturity dates ranging from 2023 to 2051. During 2022 and the first half of 2023, the Company had entered into 11 treasury lock agreements, each with a term of 10 years, with notional amounts totaling $300 million. The Company designated these treasury lock agreements as cash flow hedges, with their fair value recorded in accumulated other comprehensive gain or loss. In June 2023, the Company terminated the treasury lock agreements realizing a net gain of $3 million included in Other, net in the accompanying Consolidated Statements of Operations. No ineffectiveness was recognized on hedging instruments for the three and nine months ended September 30, 2023 or 2022.

Short-Term Debt	Note 8: Short-Term Debt Liquidity needs for capital investment, working capital and other financial commitments are generally funded through cash flows from operations, public and private debt offerings, commercial paper markets and, if and to the extent necessary, borrowings under the AWCC revolving credit facility, and issuances of equity. The revolving credit facility provides $2.75 billion in aggregate total commitments from a diversified group of financial institutions. On October 26, 2023, the termination date of the credit agreement with respect to AWCC’s revolving credit facility was extended, as permitted by the terms of the credit agreement, from October 2027 to October 2028. The revolving credit facility is used principally to support AWCC’s commercial paper program, to provide additional liquidity support and to provide a sub-limit of up to $150 million for letters of credit. As of September 30, 2023 and December 31, 2022, there were no borrowings under the revolving credit facility. As of September 30, 2023 and December 31, 2022, there were $75 million and $78 million, respectively, of outstanding letters of credit under the revolving credit facility. At September 30, 2023, there was no outstanding short-term debt. In the second quarter of 2023, the net proceeds of the Notes were used to repay the short-term commercial paper obligations. See Note 7—Long-Term Debt for additional information relating to the Notes. At December 31, 2022, short-term debt consisting of commercial paper borrowings totaled $1,177 million, or net of discount $1,175 million. The weighted-average interest rate on AWCC’s outstanding short-term borrowings was approximately 4.41% and there were no commercial paper borrowings outstanding with maturities greater than three months. Presented in the tables below is the aggregate credit facility commitments, commercial paper limit and letter of credit availability under the revolving credit facility, as well as the available capacity for each: As of September 30, 2023 Commercial Paper Limit Letters of Credit Total (a) (In millions) Total availability $ 2,600 $ 150 $ 2,750 Outstanding debt — (75) (75) Remaining availability as of September 30, 2023 $ 2,600 $ 75 $ 2,675 (a) Total remaining availability of $2.68 billion as of September 30, 2023, may be accessed through revolver draws.

Income Tax Disclosure [Abstract]
Income Taxes	Note 9: Income Taxes The Company’s effective income tax rate was 20.6% and 19.1% for the three months ended September 30, 2023 and 2022, respectively, and 21.0% and 18.9% for the nine months ended September 30, 2023 and 2022, respectively. The increase in the Company’s effective income tax rate for the three and nine months ended September 30, 2023, was primarily due to the decrease in the amortization of EADIT pursuant to regulatory orders. The amortization of EADIT is generally offset with a reduction in revenue. On August 16, 2022, the Inflation Reduction Act of 2022 (the “IRA”) was signed into law. The IRA contains a Corporate Alternative Minimum Tax (“CAMT”) provision, effective January 1, 2023. To determine if a company is considered an applicable corporation subject to CAMT, the company’s average adjusted financial statement income (“AFSI”) for the three consecutive years preceding the tax year must exceed $1 billion. An applicable corporation must make several adjustments to net income when determining AFSI. The Company evaluated the potential impacts of the CAMT provision within the IRA and believes it does not exceed the $1 billion AFSI threshold, and therefore, is not currently subject to CAMT in 2023. The Company is continuing to assess the impact of the initial guidance regarding the application of the CAMT and will continue to monitor as additional guidance is released.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11: Commitments and Contingencies Contingencies The Company is routinely involved in legal actions incident to the normal conduct of its business. As of September 30, 2023, the Company has accrued approximately $4 million of probable loss contingencies associated with such actions and has estimated that the maximum amount of loss associated with reasonably possible loss contingencies associated with such actions, which can be reasonably estimated, is $3 million. For certain legal actions, the Company is unable to estimate possible losses. The Company believes that damages or settlements, if any, recovered by plaintiffs in such actions, other than as described in this Note 11—Commitments and Contingencies, will not have a material adverse effect on the Company. Dunbar, West Virginia Water Main Break Class Action Litigation On the evening of June 23, 2015, a 36-inch pre-stressed concrete transmission water main, installed in the early 1970s, failed. The water main is part of the West Relay pumping station located in the City of Dunbar, West Virginia and owned by the Company’s West Virginia subsidiary (“WVAWC”). The failure of the main caused water outages and low pressure for up to approximately 25,000 WVAWC customers. In the early morning hours of June 25, 2015, crews completed a repair, but that same day, the repair developed a leak. On June 26, 2015, a second repair was completed, and service was restored that day to approximately 80% of the impacted customers, and to the remaining approximately 20% by the next morning. The second repair showed signs of leaking, but the water main was usable until June 29, 2015, to allow tanks to refill. The system was reconfigured to maintain service to all but approximately 3,000 customers while a final repair was being completed safely on June 30, 2015. Water service was fully restored by July 1, 2015, to all customers affected by this event. On June 2, 2017, a complaint captioned Jeffries, et al. v. West Virginia-American Water Company was filed in West Virginia Circuit Court in Kanawha County on behalf of an alleged class of residents and business owners who lost water service or pressure as a result of the Dunbar main break. The complaint alleges breach of contract by WVAWC for failure to supply water, violation of West Virginia law regarding the sufficiency of WVAWC’s facilities and negligence by WVAWC in the design, maintenance and operation of the water system. The Jeffries plaintiffs seek unspecified alleged damages on behalf of the class for lost profits, annoyance and inconvenience, and loss of use, as well as punitive damages for willful, reckless and wanton behavior in not addressing the risk of pipe failure and a large outage. In February 2020, the Jeffries plaintiffs filed a motion seeking class certification on the issues of breach of contract and negligence, and to determine the applicability of punitive damages and a multiplier for those damages if imposed. In July 2020, the Circuit Court entered an order granting the Jeffries plaintiffs’ motion for certification of a class regarding certain liability issues but denying certification of a class to determine a punitive damages multiplier. In August 2020, WVAWC filed a Petition for Writ of Prohibition in the Supreme Court of Appeals of West Virginia seeking to vacate or remand the Circuit Court’s order certifying the issues class. In January 2021, the Supreme Court of Appeals remanded the case back to the Circuit Court for further consideration in light of a decision issued in another case relating to the class certification issues raised on appeal. On July 5, 2022, the Circuit Court entered an order again certifying a class to address at trial certain liability issues but not to consider damages. On August 26, 2022, WVAWC filed another Petition for Writ of Prohibition in the Supreme Court of Appeals of West Virginia challenging the West Virginia Circuit Court’s July 5, 2022 order, which petition was denied on June 8, 2023. On August 21, 2023, the Circuit Court set a date of September 9, 2024 for a class trial on issues relating to duty and breach of that duty. The trial will not find class-wide or punitive damages. The Company and WVAWC believe that WVAWC has valid, meritorious defenses to the claims raised in this class action complaint. WVAWC is vigorously defending itself against these allegations. Given the current stage of this proceeding, the Company cannot reasonably estimate the amount of any reasonably possible loss or a range of loss related to this proceeding. Chattanooga, Tennessee Water Main Break Class Action Litigation On September 12, 2019, the Company’s Tennessee subsidiary (“TAWC”), experienced a leak in a 36-inch water transmission main, which caused service fluctuations or interruptions to TAWC customers and the issuance of a boil water notice. TAWC repaired the main by early morning on September 14, 2019, and restored full water service by the afternoon of September 15, 2019, with the boil water notice lifted for all customers on September 16, 2019. On September 17, 2019, a complaint captioned Bruce, et al. v. American Water Works Company, Inc., et al. was filed in the Circuit Court of Hamilton County, Tennessee against TAWC, the Company and American Water Works Service Company, Inc. (“Service Company” and, together with TAWC and the Company, collectively, the “Tennessee-American Water Defendants”), on behalf of a proposed class of individuals or entities who lost water service or suffered monetary losses as a result of the Chattanooga incident (the “Tennessee Plaintiffs”). The complaint alleged breach of contract and negligence against the Tennessee-American Water Defendants, as well as an equitable remedy of piercing the corporate veil. In the complaint as originally filed, the Tennessee Plaintiffs were seeking an award of unspecified alleged damages for wage losses, business and economic losses, out-of-pocket expenses, loss of use and enjoyment of property and annoyance and inconvenience, as well as punitive damages, attorneys’ fees and pre- and post-judgment interest. In September 2020, the court dismissed all of the Tennessee Plaintiffs’ claims in their complaint, except for the breach of contract claims against TAWC, which remain pending. In October 2020, TAWC answered the complaint, and the parties have been engaging in discovery. On January 12, 2023, after hearing oral argument, the court issued an oral ruling denying the Tennessee Plaintiffs’ motion for class certification. On February 9, 2023, the Tennessee Plaintiffs sought reconsideration of the ruling by the court, and any final ruling is appealable to the Tennessee Court of Appeals, as allowed under Tennessee law. On September 21, 2023, the court upheld its prior ruling but gave the Tennessee Plaintiffs the option to file an amended class definition. On October 12, 2023, the Tennessee Plaintiffs filed an amended class definition seeking certification of a business customer-only class. An order denying the original proposed class and addressing the proposed amended class has not been entered by the court and remains pending. TAWC and the Company believe that TAWC has meritorious defenses to the claims raised in this class action complaint, and TAWC is vigorously defending itself against these allegations. The Company cannot currently determine the likelihood of a loss, if any, or estimate the amount of any loss or a range of such losses related to this proceeding. Alternative Water Supply in Lieu of Carmel River Diversions Compliance with Orders to Reduce Carmel River Diversions—Monterey Peninsula Water Supply Project Under a 2009 order (the “2009 Order”) of the State Water Resources Control Board (the “SWRCB”), the Company’s California subsidiary (“Cal Am”) is required to decrease significantly its yearly diversions of water from the Carmel River according to a set reduction schedule. In 2016, the SWRCB issued an order (the “2016 Order,” and, together with the 2009 Order, the “Orders”) approving a deadline of December 31, 2021, for Cal Am’s compliance with these prior orders. Cal Am is currently involved in developing the Monterey Peninsula Water Supply Project (the “Water Supply Project”), which includes the construction of a desalination plant, to be owned by Cal Am, and the construction of wells that would supply water to the desalination plant. In addition, the Water Supply Project also includes Cal Am’s purchase of water from a groundwater replenishment project (the “GWR Project”) between Monterey One Water and the Monterey Peninsula Water Management District (the “MPWMD”). The Water Supply Project is intended, among other things, to fulfill Cal Am’s obligations under the Orders. Cal Am’s ability to move forward on the Water Supply Project is subject to administrative review by the CPUC and other government agencies, obtaining necessary permits, and intervention from other parties. In September 2016, the CPUC unanimously approved a final decision to authorize Cal Am to enter into a water purchase agreement for the GWR Project and to construct a pipeline and pump station facilities and recover up to $50 million in associated incurred costs, plus an allowance for funds used during construction (“AFUDC”), subject to meeting certain criteria. In September 2018, the CPUC unanimously approved another final decision finding that the Water Supply Project meets the CPUC’s requirements for a certificate of public convenience and necessity and an additional procedural phase was not necessary to consider alternative projects. The CPUC’s 2018 decision concludes that the Water Supply Project is the best project to address estimated future water demands in Monterey, and, in addition to the cost recovery approved in its 2016 decision, adopts Cal Am’s cost estimates for the Water Supply Project, which amounted to an aggregate of $279 million plus AFUDC at a rate representative of Cal Am’s actual financing costs. The 2018 final decision specifies the procedures for recovery of all of Cal Am’s prudently incurred costs associated with the Water Supply Project upon its completion, subject to the frameworks included in the final decision related to cost caps, operation and maintenance costs, financing, ratemaking and contingency matters. The reasonableness of the Water Supply Project costs will be reviewed by the CPUC when Cal Am seeks cost recovery for the Water Supply Project. Cal Am is also required to implement mitigation measures to avoid, minimize or offset significant environmental impacts from the construction and operation of the Water Supply Project and comply with a mitigation monitoring and reporting program, a reimbursement agreement for CPUC costs associated with that program, and reporting requirements on plant operations following placement of the Water Supply Project in service. Cal Am has incurred $233 million in aggregate costs as of September 30, 2023 related to the Water Supply Project, which includes $69 million in AFUDC. In September 2021, Cal Am, Monterey One Water and the MPWMD reached an agreement on Cal Am’s purchase of additional water from an expansion to the GWR Project, which is not expected to produce additional water until 2024 at the earliest. On December 5, 2022, the CPUC issued a final decision that authorized Cal Am to enter into the amended water purchase agreement, and specifically to increase pumping capacity and reliability of groundwater extraction from the Seaside Groundwater Basin. The final decision sets the cost cap for the proposed facilities at approximately $62 million. Cal Am may seek recovery of amounts above the cost cap in a subsequent rate filing or general rate case. Additionally, the final decision authorizes AFUDC at Cal Am’s actual weighted average cost of debt for most of the facilities. On December 30, 2022, Cal Am filed with the CPUC an application for rehearing of the CPUC’s December 5, 2022, final decision, and on March 30, 2023, the CPUC issued a decision denying Cal Am’s application for rehearing, but adopting its proposed AFUDC for already incurred and future costs. This decision also provided Cal Am the opportunity to serve supplemental testimony to increase its cost cap for certain of the Water Supply Project’s extraction wells. The amended water purchase agreement and a memorandum of understanding to negotiate certain milestones related to the expansion of the GWR Project have been signed by the relevant parties. Further hearings to be scheduled in a Phase 2 to this CPUC proceeding will focus on updated supply and demand estimates for the Water Supply Project. While Cal Am believes that its expenditures to date have been prudent and necessary to comply with the Orders, as well as relevant final decisions of the CPUC related thereto, Cal Am cannot currently predict its ability to recover all of its costs and expenses associated with the Water Supply Project and there can be no assurance that Cal Am will be able to recover all of such costs and expenses in excess of the $112 million in aggregate construction costs, plus applicable AFUDC, previously approved by the CPUC in its 2016 final decision and its December 2022 final decision, as amended by its March 30, 2023 rehearing decision. Coastal Development Permit Application In 2018, Cal Am submitted a coastal development permit application (the “Marina Application”) to the City of Marina (the “City”) for those project components of the Water Supply Project located within the City’s coastal zone. Members of the City’s Planning Commission, as well as City councilpersons, have publicly expressed opposition to the Water Supply Project. In May 2019, the City issued a notice of final local action based upon the denial by the Planning Commission of the Marina Application. Thereafter, Cal Am appealed this decision to the Coastal Commission, as permitted under the City’s code and the California Coastal Act. At the same time, Cal Am submitted an application (the “Original Jurisdiction Application”) to the Coastal Commission for a coastal development permit for those project components located within the Coastal Commission’s original jurisdiction. After Coastal Commission staff issued reports recommending denial of the Original Jurisdiction Application, noting potential impacts on environmentally sensitive habitat areas and wetlands and possible disproportionate impacts to communities of concern, in September 2020, Cal Am withdrew the Original Jurisdiction Application in order to address the staff’s environmental justice concerns. The withdrawal of the Original Jurisdiction Application did not impact Cal Am’s appeal of the City’s denial of the Marina Application, which remains pending before the Coastal Commission. In November 2020, Cal Am refiled the Original Jurisdiction Application. On October 5, 2022, Cal Am announced a phasing plan for the proposed desalination plant component of the Water Supply Project. The desalination plant and slant wells originally approved by the CPUC would produce up to 6.4 million gallons of desalinated water per day. Under the phased approach, the facilities would initially be constructed to produce up to 4.8 million gallons per day of desalinated water, enough to meet anticipated demand through about 2030, and would limit the number of slant wells initially constructed. As demand increases in the future, desalination facilities would be expanded to meet the additional demand. The phased approach seeks to meet near-term demand by allowing for additional supply as it becomes needed, while also providing an opportunity for regional future public participation and was developed by Cal Am based on feedback received from the community. On November 17, 2022, the Coastal Commission approved the Marina Application and the Original Jurisdiction Application with respect to the phased development of the proposed desalination plant, subject to compliance with a number of conditions, all of which Cal Am expects to satisfy. On December 29, 2022, the City, Marina Coast Water District (“MCWD”), MCWD’s groundwater sustainability agency, and the MPWMD jointly filed a petition for writ of mandate in Monterey County Superior Court against the Coastal Commission, alleging that the Coastal Commission violated the California Coastal Act and the California Environmental Quality Act in issuing a coastal development permit to Cal Am for construction of the slant wells. Cal Am is named as a real party in interest. This matter remains pending. Following the issuance of the coastal development permit, Cal Am continues to work constructively with all appropriate agencies to provide necessary information in connection with obtaining the remaining required permits for the Water Supply Project. However, there can be no assurance that the Water Supply Project in its current configuration will be completed on a timely basis, if ever. For the year ended December 31, 2022, Cal Am has complied with the diversion limitations contained in the 2016 Order. Continued compliance with the diversion limitations in 2023 and future years may be impacted by a number of factors, including, without limitation, continued drought conditions in California and the exhaustion of water supply reserves, and will require successful development of alternate water supply sources sufficient to meet customer demand. The Orders remain in effect until Cal Am certifies to the SWRCB, and the SWRCB concurs, that Cal Am has obtained a permanent supply of water to substitute for past unauthorized Carmel River diversions. While the Company cannot currently predict the likelihood or result of any adverse outcome associated with these matters, further attempts to comply with the Orders may result in material additional costs and obligations to Cal Am, including fines and penalties against Cal Am in the event of noncompliance with the Orders. Potential Condemnation of Monterey System Assets The water system assets of Cal Am located in Monterey, California (the “Monterey system assets”) are the subject of a potential condemnation action by the MPWMD stemming from a November 2018 public ballot initiative. In 2019, the MPWMD issued a preliminary valuation and cost of service analysis report, finding in part that (1) an estimate of the Monterey system assets’ total value plus adjustments would be approximately $513 million, (2) the cost of service modeling results indicate significant annual reductions in revenue requirements and projected monthly water bills, and (3) the acquisition of the Monterey system assets by the MPWMD would be economically feasible. In 2020, the MPWMD certified a final environmental impact report, analyzing the environmental impacts of the MPWMD’s project to (1) acquire the Monterey system assets through the power of eminent domain, if necessary, and (2) expand its geographic boundaries to include all parts of this system. In February 2021, the MPWMD filed an application with the Local Agency Formation Commission of Monterey County (“LAFCO”) seeking approval to become a retail water provider and annex approximately 58 parcels of land into the MPWMD’s boundaries. In June 2021, LAFCO’s commissioners voted to require a third-party independent financial study as to the feasibility of an acquisition by the MPWMD of the Monterey system assets. In December 2021, LAFCO’s commissioners denied the MPWMD’s application to become a retail water provider, determining that the MPWMD does not have the authority to proceed with a condemnation of the Monterey system assets. On April 1, 2022, the MPWMD filed a lawsuit against LAFCO challenging its decision to deny the MPWMD’s application seeking approval to become a retail water provider. By letter dated October 3, 2022, the MPWMD notified Cal Am of a decision to appraise the Monterey system assets and requesting access to a number of Cal Am’s properties and documents to assist the MPWMD with such an appraisal. Cal Am responded by letter on October 24, 2022, denying the request for access, stating that the MPWMD does not have the right to appraise Cal Am’s system without LAFCO approval to become a retail water provider. On April 28, 2023, Cal Am rejected an offer by the MPWMD to purchase the Monterey system assets for $448.8 million. Over the written and oral objections of Cal Am, at a hearing held on October 10, 2023, the MPWMD adopted a resolution of necessity to authorize it to file an eminent domain lawsuit with respect to the Monterey system assets. While the Company cannot currently predict the outcome of any such lawsuit, the Company believes that, given existing legal precedent related to similar attempts by public agencies in California to take over water systems, Cal Am should be able to defend itself successfully against an eminent domain lawsuit by the MPWMD. On October 25, 2023, the Monterey County Superior Court issued an Intended Statement of Decision to issue a writ of mandate directing LAFCO to vacate and set aside its original denial of the MPWMD’s application to serve as a retail water provider (in conjunction with its effort to acquire the Monterey water system assets) and to reconsider the application in compliance with all applicable law. The court held that LAFCO incorrectly applied two statutory standards and noted a lack of sufficient evidence to support certain of LAFCO’s factual findings. Once the writ of mandate is issued, the LAFCO denial will be nullified and LAFCO will be required to hold another hearing on the MPWMD’s application. Cal Am is evaluating potential actions relative to the writ of mandate, including filing an appeal or other challenge and/or making suitable presentations at a subsequent LAFCO rehearing. West Virginia Elk River Freedom Industries Chemical Spill On June 8, 2018, the U.S. District Court for the Southern District of West Virginia granted final approval of a settlement class and global class action settlement (the “Settlement”) for all claims and potential claims by all class members (collectively, the “West Virginia Plaintiffs”) arising out of the January 2014 Freedom Industries, Inc. chemical spill in West Virginia. The effective date of the Settlement was July 16, 2018. Under the terms and conditions of the Settlement, WVAWC and certain other Company affiliated entities did not admit, and will not admit, any fault or liability for any of the allegations made by the West Virginia Plaintiffs in any of the actions that were resolved. As of September 30, 2023, $0.5 million of the aggregate Settlement amount of $126 million remains reflected in accrued liabilities, and $0.5 million in an offsetting insurance receivable remains reflected in other current assets on the Consolidated Balance Sheets pending resolution of all asserted actual or potential claims associated with this matter. The amount reflected in accrued liabilities reflects the status of the liability and the offsetting insurance receivable reflected in other current assets, each as of September 30, 2023.

Earnings Per Common Share	Note 12: Earnings per Common Share Presented in the table below is a reconciliation of the numerator and denominator for the basic and diluted earnings per share (“EPS”) calculations: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2023 2022 2023 2022 Numerator: Net income attributable to common shareholders $ 323 $ 297 $ 773 $ 673 Denominator: Weighted-average common shares outstanding—Basic 195 182 192 182 Effect of dilutive common stock equivalents — — — — Weighted-average common shares outstanding—Diluted 195 182 192 182 The effect of dilutive common stock equivalents is related to outstanding restricted stock units (“RSUs”) and performance stock units (“PSUs”) granted under the Company’s 2007 Omnibus Equity Compensation Plan and outstanding RSUs and PSUs granted under the Company’s 2017 Omnibus Equity Compensation Plan, as well as estimated shares to be purchased under the Company’s 2017 Nonqualified Employee Stock Purchase Plan. Less than one million share-based awards were excluded from the computation of diluted EPS for the three and nine months ended September 30, 2023 and 2022, because their effect would have been anti-dilutive under the treasury stock method.

Fair Value of Financial Informa

Fair Value of Financial Information	9 Months Ended
Fair Value of Financial Information	Sep. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value of Financial Information	Note 13: Fair Value of Financial Information Fair Value of Financial Instruments The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments: Current assets and current liabilities—The carrying amounts reported on the Consolidated Balance Sheets for current assets and current liabilities, including revolving credit debt, due to the short-term maturities and variable interest rates, approximate their fair values. Seller promissory note from the sale of the Homeowner Services Group (“HOS”) — The carrying amount reported on the Consolidated Balance Sheets for the seller promissory note, included as part of the consideration from the sale of HOS, is $720 million as of September 30, 2023 and December 31, 2022. This amount represents the principal amount owed under the seller note, for which the Company expects to receive full payment. The accounting fair value measurement of the seller note approximated $693 million and $686 million as of September 30, 2023 and December 31, 2022, respectively. The accounting fair value measurement is an estimate that is reflective of changes in benchmark interest rates. The seller note is classified as Level 3 within the fair value hierarchy. Preferred stock with mandatory redemption requirements and long-term debt—The fair values of preferred stock with mandatory redemption requirements and long-term debt are categorized within the fair value hierarchy based on the inputs that are used to value each instrument. The fair value of long-term debt classified as Level 1 is calculated using quoted prices in active markets. Level 2 instruments are valued using observable inputs and Level 3 instruments are valued using observable and unobservable inputs. Presented in the tables below are the carrying amounts, including fair value adjustments previously recognized in acquisition purchase accounting, and the fair values of the Company’s financial instruments: As of September 30, 2023 Carrying Amount At Fair Value Level 1 Level 2 Level 3 Total Preferred stock with mandatory redemption requirements $ 3 $ — $ — $ 3 $ 3 Long-term debt 12,190 8,897 1,014 686 10,597 As of December 31, 2022 Carrying Amount At Fair Value Level 1 Level 2 Level 3 Total Preferred stock with mandatory redemption requirements $ 3 $ — $ — $ 3 $ 3 Long-term debt (excluding finance lease obligations) 11,207 8,599 49 1,427 10,075 Recurring Fair Value Measurements Presented in the tables below are assets and liabilities measured and recorded at fair value on a recurring basis and their level within the fair value hierarchy: As of September 30, 2023 Level 1 Level 2 Level 3 Total Assets: Restricted funds $ 33 $ — $ — $ 33 Rabbi trust investments 22 — — 22 Deposits 6 — — 6 Other investments Money market and other 36 — — 36 Fixed-Income Securities 148 6 — 154 Contingent cash payment from the sale of HOS — — 72 72 Total assets 245 6 72 323 Liabilities: Deferred compensation obligations 26 — — 26 Total liabilities 26 — — 26 Total assets $ 219 $ 6 $ 72 $ 297 As of December 31, 2022 Level 1 Level 2 Level 3 Total Assets: Restricted funds $ 32 $ — $ — $ 32 Rabbi trust investments 21 — — 21 Deposits 7 — — 7 Other investments Money market and other 61 — — 61 Fixed-Income Securities 147 6 — 153 Contingent cash payment from the sale of HOS — — 72 72 Mark-to-market derivative asset — 1 — 1 Total assets 268 7 72 347 Liabilities: Deferred compensation obligations 24 — — 24 Total liabilities 24 — — 24 Total assets $ 244 $ 7 $ 72 $ 323 Restricted funds—The Company’s restricted funds primarily represent proceeds received from financings for the construction and capital improvement of facilities and from customers for future services under operation, maintenance and repair projects. Rabbi trust investments—The Company’s rabbi trust investments consist of equity and index funds from which supplemental executive retirement plan benefits and deferred compensation obligations can be paid. The Company includes these assets in other long-term assets on the Consolidated Balance Sheets. Deposits—Deposits include escrow funds and certain other deposits held in trust. The Company includes cash deposits in other current assets on the Consolidated Balance Sheets. Deferred compensation obligations—The Company’s deferred compensation plans allow participants to defer certain cash compensation into notional investment accounts. The Company includes such plans in other long-term liabilities on the Consolidated Balance Sheets. The value of the Company’s deferred compensation obligations is based on the market value of the participants’ notional investment accounts. The notional investments are comprised primarily of mutual funds, which are based on observable market prices. Mark-to-market derivative assets and liabilities—The Company employs derivative financial instruments in the form of treasury lock agreements, classified as cash flow hedges, in order to fix the interest cost on existing or forecasted debt. The Company uses a calculation of future cash inflows and estimated future outflows, which are discounted, to determine the current fair value. Additional inputs to the present value calculation include the contract terms, counterparty credit risk, interest rates and market volatility. Other investments—The Company maintains a Voluntary Employees’ Beneficiary Association trust for purposes of paying active union employee medical benefits (“Active VEBA”). The investments in the Active VEBA trust primarily consist of money market funds and available-for-sale fixed income securities. The money market and other investments have original maturities of three months or less when purchased. The fair value measurement of the money market and other investments is based on observable market prices and therefore included in the recurring fair value measurements hierarchy as Level 1. The available-for-sale fixed income securities are primarily investments in U.S. Treasury securities and government bonds. The majority of U.S. Treasury securities and government bonds have been categorized as Level 1 because they trade in highly-liquid and transparent markets. Certain U.S. Treasury securities are based on prices that reflect observable market information, such as actual trade information of similar securities, and are therefore categorized as Level 2, because the valuations are calculated using models which utilize actively traded market data that the Company can corroborate. The Company includes other investments measured and recorded at fair value on the Consolidated Balance Sheets of $72 million and $67 million in Other current assets, as of September 30, 2023 and December 31, 2022, respectively, and $119 million and $147 million in Other long-term assets, as of September 30, 2023 and December 31, 2022, respectively. Unrealized holding gains and losses on available-for-sale securities are excluded from earnings and reported in other comprehensive income until realized. The following tables summarize the unrealized positions for available-for-sale fixed income securities as of September 30, 2023 and December 31, 2022: As of September 30, 2023 Amortized Cost Basis Gross unrealized gains Gross unrealized losses Fair Value Available-for-sale fixed-income securities $ 154 $ 6 $ 6 $ 154 As of December 31, 2022 Amortized Cost Basis Gross unrealized gains Gross unrealized losses Fair Value Available-for-sale fixed-income securities $ 153 $ — $ — $ 153 The fair value of the Company’s available-for-sale fixed income securities, summarized by contractual maturities, as of September 30, 2023, is as follows: Amount Other investments - Available-for-sale fixed-income securities Less than one year $ 100 1 year - 5 years 42 5 years - 10 years 3 Greater than 10 years 9 Total $ 154

Leases

Leases	9 Months Ended
Leases	Sep. 30, 2023
Leases [Abstract]
Leases	Note 14: Leases The Company has operating and finance leases involving real property, including facilities, utility assets, vehicles, and equipment. Certain operating leases have renewal options ranging from one year to 60 years. The exercise of lease renewal options is at the Company’s sole discretion. Renewal options that the Company was reasonably certain to exercise are included in the Company’s right-of-use (“ROU”) assets. Certain operating leases contain the option to purchase the leased property. The operating leases for real property, vehicles and equipment will expire over the next 36 years, six years, and five years, respectively. The Company participates in a number of arrangements with various public entities (“Partners”) in West Virginia. Under these arrangements, the Company transferred a portion of its utility plant to the Partners in exchange for an equal principal amount of Industrial Development Bonds (“IDBs”) issued by the Partners under the Industrial Development and Commercial Development Bond Act.

Segment Reporting [Abstract]
Segment Information	Note 15: Segment Information The Company’s operating segments are comprised of its businesses which generate revenue, incur expense and have separate financial information which is regularly used by management to make operating decisions, assess performance and allocate resources. The Company operates primarily through one reportable segment, the Regulated Businesses segment. The Regulated Businesses segment also includes inter-segment revenues, costs and interest which are eliminated to reconcile to the Consolidated Statements of Operations. The Company also operates other businesses, primarily MSG, that do not meet the criteria of a reportable segment in accordance with GAAP and are collectively presented throughout this Form 10-Q within “Other,” which is consistent with how management assesses the results of these businesses. Other also includes corporate costs that are not allocated to the Company’s Regulated Businesses, interest income related to the seller promissory note and income from the revenue share agreement from the sale of HOS, eliminations of inter-segment transactions and fair value adjustments related to acquisitions that have not been allocated to the Regulated Businesses segment. The adjustments related to the acquisitions are reported in Other as they are excluded from segment performance measures evaluated by management. On December 9, 2021, the Company sold all of the equity interests of the HOS subsidiaries, for a total consideration of approximately $1.275 billion. The consideration was comprised of $480 million in cash, a seller promissory note in the principal amount of $720 million, and a contingent cash payment of $75 million payable upon satisfaction of certain conditions on or before December 31, 2023. See Note 13—Fair Value of Financial Information for additional information relating to the seller promissory note and contingent cash payment. The seller promissory note from the sale of HOS, has a five-year term, is payable in cash, and bears interest at a rate of 7.00% per year during the term. The Company recognized $13 million of interest income from the seller note for each of the three months ended September 30, 2023 and 2022, and $38 million of interest income from the seller note for each of the nine months ended September 30, 2023 and 2022. The Company recognized $3 million and $2 million of income during the three months ended September 30, 2023 and 2022, respectively, and $9 million and $6 million of income during the nine months ended September 30, 2023 and 2022, respectively, from the revenue share agreements from the sale of HOS, which is included in Other, net on the Consolidated Statements of Operations.

Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Standards	New Accounting Standards Presented in the table below are new accounting standards that were adopted by the Company in 2023: Standard Description Date of Adoption Application Effect on the Consolidated Financial Statements Accounting for Contract Assets and Contract Liabilities from Contracts with Customers The guidance requires an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification Topic 606, as if it had originated the contracts. The amendments in this update also provide certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. January 1, 2023 Prospective This standard did not have a material impact on the Consolidated Financial Statements Troubled Debt Restructurings and Vintage Disclosures The main provisions of this standard eliminate the receivables accounting guidance for troubled debt restructurings (“TDRs”) by creditors while enhancing disclosure requirements when a borrower is experiencing financial difficulty. Entities must apply the loan refinancing and restructuring guidance for receivables to determine whether a modification results in a new loan or a continuation of an existing loan. Additionally, the amendments in this update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases. January 1, 2023 Prospective, with a modified retrospective option for amendments related to the recognition and measurement of TDRs. This standard did not have a material impact on the Consolidated Financial Statements Presentation and Disclosure Requirements The guidance amends GAAP disclosure and presentation requirements for various subtopics in the Financial Accounting Standards Board Codification and was issued in response to the U.S. Securities and Exchange Commission’s (“SEC”) final rule published in August 2018 that updated and simplified disclosure requirements that it believed were outdated, superseded, overlapping, duplicative and redundant. The new guidance is intended to align GAAP requirements with those of the SEC for all entities. The date on which the SEC’s removal of the related disclosure requirement became effective Prospective This standard did not have a material impact on the Consolidated Financial Statements
Property, Plant and Equipment	Property, Plant and Equipment The New Jersey Economic Development Authority (“NJEDA”) determined that the Company was qualified to receive $161 million in tax credits in connection with its capital investment in its corporate headquarters in Camden, New Jersey. The Company was qualified to receive the tax credits over a 10-year period commencing in 2019.
Allowance for Uncollectible Accounts	Allowance for Uncollectible Accounts Allowances for uncollectible accounts are maintained for estimated probable losses resulting from the Company’s inability to collect receivables from customers. Accounts that are outstanding longer than the payment terms are considered past due. A number of factors are considered in determining the allowance for uncollectible accounts, including the length of time receivables are past due, previous loss history, current economic and societal conditions and reasonable and supportable forecasts that affect the collectability of receivables from customers. The Company generally writes off accounts when they become uncollectible or are over a certain number of days outstanding.
Reclassifications	Reclassifications Certain reclassifications have been made to prior periods in the Consolidated Financial Statements and Notes to conform to the current presentation.
