• changes in general economic, political, business and financial market conditions;

• access to sufficient capital on satisfactory terms and when and as needed to support operations and capital expenditures;

• fluctuations in interest rates;

• restrictive covenants in or changes to the credit ratings on our current or future debt that could increase our financing costs or funding requirements or affect our ability to borrow, make payments on debt or pay dividends;

• fluctuations in the value of benefit plan assets and liabilities that could increase our cost and funding requirements;

Except as required by the federal securities laws, we do not have any obligation, and we specifically disclaim any undertaking or intention, to publicly update or revise any forward-looking statements, whether as a result of new information, future events, changed circumstances or otherwise. New factors emerge from time to time, and it is not possible for us to predict all such factors. Furthermore, it may not be possible to assess the impact of any such factor on our businesses, either viewed independently or together, or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. The foregoing factors should not be construed as exhaustive.

American Water Works Company, Inc. and Subsidiary Companies

Notes to Consolidated Financial Statements (Unaudited)

(Unless otherwise noted, in millions, except per share data)

Note 1: Basis of Presentation

The unaudited consolidated financial statements provided in this report include the accounts of American Water Works Company, Inc. and all of its subsidiaries (collectively, “American Water” or the “Company”) in which a controlling interest is maintained after the elimination of intercompany accounts and transactions. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting and with the rules and regulations for reporting on 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 June 30, 2017 and 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 Consolidated Balance Sheet as of December 31, 2016 is derived from the Company's audited consolidated financial statements as of December 31, 2016. 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, 2016 (“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, due primarily to the seasonality of the Company’s operations.

Note 2: New Accounting Standards

The Company adopted the following accounting standard on January 1, 2017:

Standard	Description	Date of Adoption	Application	Estimated Effect on the Consolidated Financial Statements (or Other Significant Matters)
Simplification of Employee Share-Based Payment Accounting	Simplified accounting and disclosure requirements for share-based payment awards. The updated guidance addresses simplification in areas such as: (i) the recognition of excess tax benefits and deficiencies; (ii) the classification of excess tax benefits and taxes paid on the Consolidated Statements of Cash Flows; (iii) election of an accounting policy for forfeitures; and (iv) the amount an employer can withhold to cover income taxes and still qualify for equity classification.	January 1, 2017	Modified retrospective for the recognition of excess tax benefits and deficiencies; full retrospective for the classification of excess tax benefits and taxes paid on the Consolidated Statements of Cash Flows	The adoption of this standard resulted in a cumulative effect to increase retained earnings by $21, with an offsetting decrease to deferred income taxes, net. Also, the adoption resulted in a net increase in cash flows from operating activities and a net decrease in cash flows from financing activities of $14 and $18 for the six months ended June 30, 2017 and 2016, respectively, on the Consolidated Statements of Cash Flows.

The following recently issued accounting standards are not yet required to be adopted by the Company as of June 30, 2017:

Standard	Description	Date of Adoption	Permitted Application	Estimated Effect on the Consolidated Financial Statements (or Other Significant Matters)
Revenue from Contracts with Customers	Changes the criteria for recognizing revenue from a contract with a customer. Replaces existing guidance on revenue recognition, including most industry specific guidance. The objective is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets.  The underlying principle is that an entity will recognize revenue to depict the transfer of goods and services to customers at an amount the entity expects to be entitled to in exchange for those goods or services.  The guidance also requires a number of disclosures regarding the nature, amount, timing and uncertainty of revenue and the related cash flows.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company substantially completed its evaluation of the requirements of the new standard based on current interpretations and does not expect there to be a change in the measurement or timing of revenue recognized. The Company continues to monitor for new authoritative and interpretative guidance, which upon release could impact the Company’s current evaluation. The Company plans to adopt the new standard on January 1, 2018 using the modified retrospective method.
Classification of Certain Cash Receipts and Cash Payments on the Statement of Cash Flows	Provides guidance on the presentation and classification in the statement of cash flows for the following cash receipts and payments: (i) debt prepayment or debt extinguishment costs; (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (iii) contingent consideration payments made after a business combination; (iv) proceeds from the settlement of insurance claims; (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (vi) distributions received from equity method investees; (vii) beneficial interests in securitization transactions and (viii) separately identifiable cash flows and application of the predominance principle.	January 1, 2018; early adoption permitted	Retrospective	The Company does not anticipate significant impacts on its consolidated statements of cash flows.
Presentation of Changes in Restricted Cash on the Statement of Cash Flows	Updates the accounting and disclosure guidance for the classification and presentation of changes in restricted cash on the statements of cash flows. The amended guidance requires that the statements of cash flows explain the change during the period in the total of cash, cash equivalents and amounts described as restricted cash or restricted cash equivalents. Restricted cash and restricted cash equivalents will now be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows.	January 1, 2018; early adoption permitted	Retrospective	The Company does not anticipate significant impacts on its consolidated statements of cash flows.
Clarifying the Definition of a Business	Updates the accounting guidance to clarify the definition of a business with the objective of assisting entities with evaluating whether transactions should be accounted for as acquisitions, or disposals, of assets or businesses.	January 1, 2018; early adoption permitted	Prospective	The update could result in more acquisitions being accounted for as asset acquisitions. The effect on the Company's consolidated financial statements will be dependent on the transactions executed by the Company subsequent to adoption.
Gains and Losses from the Derecognition of Nonfinancial Assets	Updated the guidance to clarify the accounting for gains and losses resulting from the derecognition of nonfinancial assets and partial sale of nonfinancial assets. The guidance also clarifies the definition of an in-substance nonfinancial asset.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company is evaluating the impact on its consolidated financial statements and related disclosures.
Presentation of Net Periodic Pension Cost and Net Periodic  Postretirement Benefit Cost	Updated authoritative guidance requires the service cost component of net periodic benefit cost to be presented in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. The remaining components of net periodic benefit cost are required to be presented separately from the service cost component in an income statement line item outside of operating income. Also, the guidance allows for only the service cost component to be eligible for capitalization. The updated guidance does not impact the accounting for net periodic benefit costs as regulatory assets or liabilities.

Standard	Description	Date of Adoption	Permitted Application	Estimated Effect on the Consolidated Financial Statements (or Other Significant Matters)
Accounting for Leases	Updated the accounting and disclosure guidance for leasing arrangements. Under this guidance, a lessee will be required to recognize the following for all leases, excluding short-term leases, at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the guidance, lessor accounting is largely unchanged.	January 1, 2019; early adoption permitted	Modified retrospective	The Company is evaluating the effect on its consolidated financial statements and related disclosures.
Simplification of Goodwill Impairment Testing	Updated authoritative guidance which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amendments in the update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying value exceeds the reporting unit's fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.	January 1, 2020; early adoption permitted	Prospective	The Company is considering early adopting this guidance for its next annual goodwill impairment test, which will occur during the fourth quarter of 2017. The Company does not expect the adoption to have a material impact on its consolidated financial statements or related disclosures.
Measurement of Credit Losses	Updated the accounting guidance on reporting credit losses for financial assets held at amortized cost basis and available-for-sale debt securities. Under this guidance, expected credit losses are required to be measured based on historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount of financial assets. Also, this guidance requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a direct write-down.	January 1, 2020; early adoption permitted	Modified retrospective	The Company is evaluating the impact on its consolidated financial statements and related disclosures, as well as the timing of adoption.

Note 3: Acquisitions

During the six months ended June 30, 2017, the Company closed on ten acquisitions of various regulated water and wastewater systems for a total aggregate purchase price of $42. Included in this total was the Company’s acquisition of all the outstanding capital stock of the Shorelands Water Company, Inc. on April 3, 2017, for total consideration of $33, in the form of approximately 0.4 shares of the Company’s common stock. Assets acquired for the aforementioned acquisitions, principally utility plant, totaled $37. Liabilities assumed totaled $21, including $7 of contributions in aid of construction and assumed debt of $7. The Company recorded additional goodwill of $28associated with three of its acquisitions, which is reported in the Company’s Regulated Businesses segment.  The Company also recognized a bargain purchase gain of $2 associated with one of these acquisitions. The preliminary purchase price allocations related to these acquisitions will be finalized once the valuation of assets acquired has been completed, no later than one year after their acquisition date.

Also, the Company made a non-escrowed deposit of $2 during the first quarter of 2017 related to the acquisition of the McKeesport, Pennsylvania wastewater system, which the Company expects to close by the first quarter of 2018.

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 capitalized as a regulatory asset. These accumulated other comprehensive income loss components are included in the computation of net periodic pension cost. See Note 8— Pension and Other Postretirement Benefits.

The amortization of the 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.

Anti-dilutive Stock Repurchase Program

During the six months ended June 30, 2017, the Company repurchased 0.7 shares of common stock in the open market at an aggregate cost of $54 under the anti-dilutive stock repurchase program authorized by the Company’s Board of Directors in 2015. As of June 30, 2017, there were 6.1 shares of common stock available for repurchase under the program.

Note 5: Stock Based Compensation

On May 12, 2017, the Company’s stockholders approved the American Water Works Company, Inc. 2017 Omnibus Equity Compensation Plan (the “2017 Omnibus Plan”). A total of 7.2 million shares of common stock may be issued under the 2017 Omnibus Plan. The 2017 Omnibus Plan provides that grants of awards may be in any of the following forms: incentive stock options, nonqualified stock options, stock appreciation rights, stock units, stock awards, other stock-based awards and dividend equivalents, which may be granted only on stock units or other stock-based awards.

Note 6: Long-Term Debt

The following long-term debt was issued during the six months ended June 30, 2017:

Company	Type	Rate		Maturity	Amount
Other American Water subsidiaries	Private activity bonds and government funded debt—fixed rate	0.00%-3.92%		2020-2036	$	16
Other American Water subsidiaries	Term Loan		4.47%	2021		4
Total issuances					$	20

The following long-term debt was retired through sinking fund provisions, optional redemptions or payment at maturity during the six months ended June 30, 2017:

Company	Type	Rate		Maturity	Amount
American Water Capital Corp. (a)	Private activity bonds and government funded debt—fixed rate	1.79%-2.90%		2021-2031	$	1
Other American Water subsidiaries	Private activity bonds and government funded debt—fixed rate	0.00%-5.38%		2017-2041		4
Other American Water subsidiaries	Mandatorily redeemable preferred stock		8.49%	2036		1
Total retirements and redemptions					$	6

(a) American Water Capital Corp., which is a wholly owned subsidiary of the Company, has a support agreement with the Company that, under certain circumstances, is the functional equivalent of a parent company guarantee. This indebtedness is considered “debt” for purposes of this support agreement.

The Company has four forward starting swap agreements with an aggregate notional amount of $300 to reduce interest rate exposure on debt expected to be issued in 2017. These forward starting swap agreements terminate in December 2017 and have an average fixed rate of 2.20%. On February 8, 2017, the Company entered into an additional forward starting swap agreement with a notional amount of $100 to reduce interest rate exposure for a portion of the expected refinancing of the Company’s 5.62% fixed-rate long-term debt maturing in December 2018. This forward starting swap agreement terminates in November 2018 and has an average fixed rate of 2.67%. The Company has designated theseforward starting swap agreements as cash flow hedges and the initial fair value, in addition to any subsequent changes in fair value, are recognized in accumulated other comprehensive gain or loss. Upon termination, the cumulative gain or loss recorded in accumulated other comprehensive gain or loss will be amortized through interest, net over the term of the issued debt.

The Company has an interest rate swap to hedge $100 of its 6.085% fixed-rate debt maturing in 2017. The Company pays variable interest of six-month LIBOR plus 3.422% and the interest rate swap matures with the fixed-rate debt in 2017. The Company has designated this interest rate swap as a fair value hedge accounted for at fair value with gains or losses, as well as the offsetting gains or losses on the hedged item, recognized in interest, net. The net gain and loss recognized by the Company for the three and six months ended June 30, 2017 and 2016 was de minimis.

The Company has employed interest rate swaps to fix the interest cost on a portion of its variable-rate debt with an aggregate notional amount of $6. The Company has designated these interest rate swaps as economic hedges accounted for at fair value with gains or losses deferred as a regulatory asset or regulatory liability. The net gain recognized by the Company for the three and six months ended June 30, 2017 and 2016 was de minimis.

No ineffectiveness was recognized for the three and six months ended June 30, 2017 and 2016, related to hedging instruments.

Note 7: Income Taxes

The Company’s effective income tax rate was41.8%and39.1%for the three months ended June 30, 2017 and 2016, respectively, and 39.5% and 39.4% for thesix months ended June 30, 2017 and 2016, respectively. The effective income tax rate for the three months ended June 30, 2017 increased when compared to the same period in 2016 due to aone-time, non-cash cumulative charge to the provision for income taxes of $4, primarily the result of legislation enacted in the State of New York during the second quarter of 2017, and a tax benefit of $3 that was recorded during the second quarter of 2016.This increase in the effective income tax rate was partially offset for the six months ended June 30, 2017, by a $5 tax benefit from the new accounting standard for employee share-based payment awards which was adopted in the first quarter of 2017. Under this updated guidance, tax benefits or shortfalls related to employee share-based payments awards are recognized in the provision for income taxes, whereas they previously were recorded as additional paid-in capital on the Consolidated Balance Sheet. See Note 2 – New Accounting Standards in the Notes to Consolidated Financial Statements for further discussion on the impacts of the updated guidance.

On April 11, 2017, the State of New York enacted legislation that increased the state income tax rate on the Company’s taxable income attributable to New York. This legislation eliminated the production of water as a qualified manufacturing activity in New York, which effectively increased the state income tax rate in New York. As a result of the legislative change, the Company was required to re-measure its cumulative deferred tax balances using the higher state income tax rate in the second quarter of 2017. This change in legislation was the primary cause of an increase to the Company’s unitary deferred tax liability of $11. The portion of this increase related to the Company’s New York subsidiary calculated on a stand-alone basis was $7, and was offset by a regulatory asset, as the Company believes it is probable of recovery in future rates. The remaining increase in the deferred tax liability was calculated through state tax apportionment rates and recorded at the consolidated level, resulting in a non-cash, cumulative charge to earnings of $4during the second quarter of 2017.

On July 7, 2017, the State of Illinois enacted legislation that would increase the state income tax rate on the Company’s taxable income attributable to Illinois from 7.75% to 9.5%. The effective date of the increase in the state tax rate is July 1, 2017. As a result of the legislative change, the Company will be required to re-measure its cumulative deferred tax balances using the higher state income tax rate in the third quarter of 2017. The portion of this increase related to the Company’s Illinois subsidiary calculated on a stand-alone basis is expected to be offset by a regulatory asset, as the Company believes it is probable of recovery in future rates. The remaining increase in the deferred tax liability will be calculated through state tax apportionment rates and recorded at the consolidated level, as a non-cash, cumulative charge to earnings during the third quarter of 2017.

The Company made contributions for the funding of its defined benefit pension plans of $10 and $8 for the three months ended June 30, 2017 and 2016, respectively, and $20 and $17 for the six months ended June 30, 2017 and 2016, respectively, and expects to contribute $20during the remainder of 2017. In addition, the Company made contributions for the funding of its other postretirement plans of $2 and $6 for the three months ended June 30, 2017 and 2016, respectively, and $3 and $11 for the six months ended June 30, 2017 and 2016, respectively, and expects to contribute $3 during the remainder of 2017.

Note 9: Commitments and Contingencies

Contingencies

The Company is routinely involved in legal actions incident to the normal conduct of its business. As of June 30, 2017, the Company has accrued approximately $139 of probable loss contingencies and has estimated that the maximum amount of losses associated with reasonably possible loss contingencies that can be reasonably estimated is $28. For certain matters, claims and actions, the Company is unable to estimate possible losses. The Company believes that damages or settlements, if any, recovered by plaintiffs in such matters, claims or actions, other than as described in this Note 9, will not have a material adverse effect on the Company.

West Virginia Elk River Freedom Industries Chemical Spill

Background

On January 9, 2014, a chemical storage tank owned by Freedom Industries, Inc. leaked two substances, 4-methylcyclohexane methanol, or MCHM, and PPH/DiPPH, a mix of polyglycol ethers, into the Elk River near the West Virginia-American Water Company (“WVAWC”) treatment plant intake in Charleston, West Virginia. After having been alerted to the leak of MCHM by the West Virginia Department of Environmental Protection (“DEP”), WVAWC took immediate steps to gather more information about MCHM, augment its treatment process as a precaution, and begin consultations with federal, state and local public health officials. As soon as possible after it was determined that the augmented treatment process would not fully remove the MCHM, a joint decision was reached in consultation with the West Virginia Bureau for Public Health to issue a “Do Not Use” order for all of its approximately 93,000 customer accounts in parts of nine West Virginia counties served by the Charleston treatment plant. By January 18, 2014, none of WVAWC’s customers were subject to the Do Not Use order.

15

Following the Freedom Industries chemical spill, numerous lawsuits were filed against WVAWC and certain other Company affiliated entities (collectively, the “American Water Defendants”) with respect to this matter in the U.S. District Court for the Southern District of West Virginia or West Virginia Circuit Courts in Kanawha, Boone and Putnam counties, and to date, 74 cases remain pending. Four of the cases pending before the U.S. district court were consolidated for purposes of discovery, and an amended consolidated class action complaint for those cases (the “Federal action”) was filed in December 2014 by several plaintiffs. On January 28, 2016, all of the then-filed state court cases were referred to West Virginia’s Mass Litigation Panel for further proceedings, which have been stayed pending the negotiation by the parties and approval by the court in the Federal action of a global agreement to settle all of such cases, as described below. On July 7, 2016, the court in the Federal action scheduled trial to begin on October 25, 2016, but the court has granted several continuances of the trial, which is currently postponed indefinitely in light of the binding global agreement in principle described below. The Mass Litigation Panel has also stayed its proceedings until October 23, 2017.

WVAWC Binding Global Agreement in Principle to Settle Claims

On October 31, 2016, the court in the Federal action approved the preliminary principles, terms and conditions of a binding global agreement in principle to settle claims (the “Settlement”) among the American Water Defendants, and all class members, putative class members, claimants and potential claimants (collectively, the “Plaintiffs”), arising out of the Freedom Industries chemical spill. The terms of the Settlement propose a global federal and state resolution of all litigation and potential claims against the American Water Defendants and their insurers. A claimant may elect to opt out of any final settlement agreement, in which case such claimant will not receive any benefit from or be bound by the terms of the Settlement. Under the terms and conditions of the Settlement and any subsequent final settlement agreement, the American Water Defendants have not admitted, and will not admit, any fault or liability for any of the allegations made by the Plaintiffs in any of the actions to be resolved.

The proposed aggregate pre-tax amount of the Settlement is $126, of which $65 would be contributed by WVAWC, and the remainder would be contributed by certain of the Company’s general liability insurance carriers. The Company has general liability insurance under a series of policies underwritten by a number of individual carriers. Two of these insurance carriers, which provide an aggregate of $50 in insurance coverage to the Company under these policies, were requested, but presently have not agreed, to participate in the Settlement. The Company and WVAWC are vigorously pursuing their rights to insurance coverage from these non-participating carriers for any contributions by WVAWC to the Settlement. In this regard, WVAWC filed a lawsuit against one of these carriers alleging that the carrier’s failure to agree to participate in the Settlement constitutes a breach of contract, and the Company is pursuing mandatory arbitration against the other non-participating carrier.

The preliminary terms of the Settlement intend to establish a two-tier settlement fund for the payment of claims, comprised of (i) a simple claim fund, which is also referred to as the “guaranteed fund,” of $76, of which $51 will be contributed by WVAWC, including insurance deductibles, and $25 would be contributed by one of the Company’s general liability insurance carriers, and (ii) an individual review claim fund of up to $50, of which up to $14 would be contributed by WVAWC and $36 would be contributed by a number of the Company’s general liability insurance carriers. Separately, up to $25 would be contributed to the guaranteed fund by another defendant to the Settlement.

As a result of these events, the Company recorded a charge to earnings, net of insurance receivables, of $65 ($39 after-tax) in the third quarter of 2016. The settlement amount of $126 is reflected in Accrued Liabilities and the offsetting insurance receivable is reflected in Other Current Assets in the Consolidated Balance Sheet as of June 30, 2017. The Company intends to fund WVAWC’s contributions to the Settlement through existing sources of liquidity, although no contribution by WVAWC will be required unless and until the terms of the Settlement are finally approved by the court in the Federal action. Furthermore, under the terms of the Settlement, WVAWC has agreed that it will not seek rate recovery from the Public Service Commission of West Virginia for approximately $4 in direct response costs expensed in 2014 by WVAWC relating to the Freedom Industries chemical spill as well as for amounts paid by WVAWC under the Settlement.

The Company’s insurance policies operate under a layered structure where coverage is generally provided in the upper layers after claims have exhausted lower layers of coverage. The $36 to be contributed by a number of the Company’s general liability insurance carriers to the individual review claim fund, as noted above, is from higher layers of the insurance structure than the two insurance carriers that were requested, but presently have not agreed, to participate in the Settlement. Any recovery by WVAWC or the Company from the non-participating carriers would reimburse WVAWC for its contributions to the guaranteed fund.

On April 27, 2017, the parties filed with the court in the Federal action a proposed settlement agreement providing details of the terms of the Settlement consistent with those described above. The parties also requested that the court in the Federal action grant preliminary approval of the Settlement.

16

On July 6, 2017, the court in the Federal action issued an opinion denying without prejudice the joint motion for preliminary approval of the Settlement. The court in the Federal action found the overall amount and structure of the Settlement to be fair, adequate and reasonable, but it declined to preliminarily approve the Settlement on several grounds, including the fairness of the methodology for allocating payments among members of the business class, the nature of the claims appeal process and the timing of the payment of claims that are subject to appeal, and the fairness of setting of fixed payments for the medical claims class. The American Water Defendants intend to work with the Plaintiffs to propose acceptable alternative provisions to the Settlement Agreement to satisfy the concerns of the court in the Federal action. If and when preliminary approval of the Settlement is obtained, notice of the terms of the Settlement would then be provided to members of the settlement class. Following the notice period, the court in the Federal action would hold a fairness hearing to consider final approval of the Settlement.

Other Related Proceedings

Additionally, investigations with respect to the matter have been initiated by the U.S. Chemical Safety and Hazard Investigation Board (the “CSB”), the U.S. Attorney’s Office for the Southern District of West Virginia, the West Virginia Attorney General, and the Public Service Commission of West Virginia (the “PSC”). As a result of the U.S. Attorney’s Office investigation, Freedom Industries and six former Freedom Industries employees (three of whom also were former owners of Freedom Industries), pled guilty to violations of the federal Clean Water Act.

In May 2014, the PSC issued an Order initiating a General Investigation into certain matters relating to WVAWC’s response to the Freedom Industries chemical spill. Three parties intervened in the proceeding, including the Consumer Advocate Division of the PSC and two attorney-sponsored groups, including one sponsored by some of the plaintiffs’ counsel involved in the civil litigation described above. On January 26, 2017, WVAWC and the other parties agreed to resolve the General Investigation and filed a joint stipulation with the PSC containing the terms of the settlement. The parties to the joint stipulation filed a proposed order with the PSC on February 8, 2017. On June 15, 2017, the PSC entered an order accepting the joint stipulation that had been filed by the parties in January 2017 as a reasonable basis for resolving the General Investigation and removing the proceeding from the docket. The PSC’s order did not require WVAWC to take any further action with respect to the matters covered by the General Investigation. The PSC order concludes the General Investigation.

The CSB is an independent investigatory agency with no regulatory mandate or ability to issue fines or citations; rather, the CSB can only issue recommendations for further action. In response to the Freedom Industries chemical spill, the CSB commenced an investigation shortly thereafter. On September 28, 2016, the CSB issued and adopted its investigation report in which it recommended that the Company conduct additional source water protection activities. The Company provided written comments to the CSB’s report suggesting that the recommendation made to the Company would be better directed to the U.S. Environmental Protection Agency in order to promote industry-wide implementation of the CSB’s recommendation. On February 15, 2017, the Company filed a response to the CSB’s recommendation. On April 4, 2017, the CSB indicated that the implementation by the Company of source water protection activities resolved the first two parts of the CSB’s recommendation. The CSB also noted that compliance by the Company with the third part of its recommendation is ongoing and that closure of this part is contingent upon completion of updated contingency planning for the Company’s water utilities outside of West Virginia. In light of public response to its original September 2016 investigation report, on May 11, 2017, the CSB issued a new version of this report. The primary substantive change addressed CSB’s factual evaluation of the duration and volume of contamination from the leaking tank, decreasing its estimate of the leak time but increasing the volume estimate by 10%. No substantive changes were made to the conclusions and recommendations in the original report.

On March 16, 2017, the Lincoln County (West Virginia) Commission (the “LCC”) passed a county ordinance entitled the “Lincoln County, WV Comprehensive Public Nuisance Investigation and Abatement Ordinance.” The ordinance establishes a mechanism that Lincoln County believes will allow it to pursue criminal or civil proceedings for the “public nuisance” it alleges was caused by the Freedom Industries chemical spill. On April 20, 2017, the LCC filed a complaint in Lincoln County state court against WVAWC and certain other defendants not affiliated with the Company, alleging that the Freedom Industries chemical spill caused a public nuisance in Lincoln County. On June 12, 2017, the Mass Litigation Panel entered an order granting a motion to transfer this case to its jurisdiction and stayed the case consistent with the existing stay order. The complaint seeks an injunction against WVAWC that would require the creation of various databases and public repositories of documents related to this chemical spill, as well as further study and risk assessments regarding the alleged exposure by Lincoln County residents to the released chemicals. WVAWC believes that the lawsuit is without merit and intends to vigorously contest the claims and allegations raised in the complaint.

California Public Utilities Commission Residential Rate Design Proceeding

In December 2016, the California Public Utilities Commission (the “CPUC”) issued a final decision in a proceeding involving California-American Water Company, the Company’s wholly owned subsidiary (“Cal Am”), adopting a new residential rate design for Cal Am’s Monterey District. The decision allowed for recovery by Cal Am of $32 in under-collections in the water revenue adjustment mechanism/modified cost balancing account (“WRAM/MCBA”) over a five-year period, plus interest, and modified existing conservation and rationing plans. In its decision, the CPUC noted concern regarding Cal Am’s residential tariff administration, specifically regarding the lack of verification of customer-provided information about the number of residents per household. This information was used for generating billing determinants under the tiered rate system. As a result, the CPUC kept this proceeding open to address several issues, including whether Cal Am’s residential tariff administration violated a statute, rule or CPUC decision, and if so, whether a penalty should be imposed.

On February 24, 2017, Cal Am, the Monterey Peninsula Water Management District, the CPUC’s Office of Ratepayer Advocates, and the Coalition of Peninsula Businesses filed for CPUC approval of a joint settlement agreement (the “Joint Settlement Agreement”), which among other things, proposed to resolve the CPUC’s residential tariff administration concerns by providing for a waiver by Cal Am of $0.5 of cost recovery for residential customers through the WRAM/MCBA in lieu of a penalty. Approval of the Joint Settlement Agreement, which is required for it to take effect, remains pending before the CPUC.

On March 28, 2017, the administrative law judge assigned to the proceeding issued a ruling stating there was sufficient evidence to conclude, on a preliminary basis, that Cal Am’s administration of the residential tariff violated certain provisions of the California Public Utilities Code and a CPUC decision. The ruling ordered Cal Am to show cause why it should not be penalized for these administrative violations and directed the settling parties to address whether the cost recovery waiver in the Joint Settlement Agreement was reasonable compared to a potential penalty range described by the administrative law judge. During hearings held on April 13-14, 2017, the administrative law judge clarified that this potential penalty range is $3 to $179 (calculated as a continuing violation dating back to 2000 and applying penalties of up to $20 thousand per day until January 1, 2012 and penalties of up to $50 thousand per day thereafter, reflecting a 2012 change to the relevant statute). The administrative law judge also noted that a per diem penalty may not be appropriate, as Cal Am’s monthly billing practices did not allow Cal Am to update customer-provided information for billing purposes on a daily basis. The administrative law judge has set further hearings in this proceeding for August 17, 2017, and has permitted certain of the parties, including Cal Am, to submit additional written testimony on the issue of whether Cal Am should be penalized, and if so, the reasonable amount of any such penalty.

As of June 30, 2017, the portions of this loss contingency that are probable and/or reasonable possible have been determined to be immaterial to the Company and have been included in the aggregate maximum amounts described above in the first paragraph of “Contingencies” in this Note 9.

Missouri Infrastructure System Replacement Surcharge Litigation

In March 2016, the Western District of the Missouri Court of Appeals ruled that the Missouri Public Service Commission (“MoPSC”) did not have statutory authority to issue an order in June 2015 approving an infrastructure system replacement surcharge (“ISRS”) for Missouri-American Water Company (“MAWC”), a wholly owned subsidiary of the Company. The court held that the MoPSC’s June 2015 order authorizing the ISRS increase was invalid because St. Louis County did not have a population of at least one million residents, asrequired by the statute. MAWC believes that the MoPSC’s June 2015 order authorizing the collection of ISRS revenues is lawful. In June 2016, the Missouri Supreme Court granted MAWC’s application to transfer the case from the Court of Appeals to the Missouri Supreme Court, and as a result of that order, the March 2016 ruling of the Court of Appeals was vacated.

On March 14, 2017, in a unanimous decision, the Missouri Supreme Court dismissed the case as moot, finding that there were no longer any ISRS funds in dispute because MAWC had completed a rate case during the appellate process and the disputed charges were now incorporated in base rates. On May 30, 2017, the Missouri Supreme Court denied a Motion for Rehearing filed by the Missouri Office of Public Counsel, which action concluded the litigation in this matter.

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 WVAWC’s West Relay pumping station located in the City of Dunbar. The failure of the main caused water outages and low pressure to 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 completed safely on June 30, 2015. Water service was fully restored on July 1, 2015 to all customers affected by this event.

18

On June 2, 2017, a class action complaint was filed in West Virginia Circuit Court in Kanawha County against WVAWC on behalf of a purported 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 plaintiff seeks 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.

The Company and WVAWC believe that WVAWC has valid, meritorious defenses to the claims raised in this class action complaint. WVAWC intends to vigorously defend itself against these allegations. Given the current stage of this proceeding, the Company cannot reasonably estimate the amount of any reasonably possible losses or a range of such losses related to this proceeding.

Note 11: Fair Value of Financial Assets and Liabilities

Fair Value of Financial Instruments

The Company used the following methods and assumptions to estimate its fair value disclosures for financial instruments:

Current assets and current liabilities—The carrying amounts reported in the accompanying 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.

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. The fair values of instruments classified as Level 2 and Level 3 are determined by a valuation model that is based on a conventional discounted cash flow methodology and utilizes assumptions of current market rates. As a portion of the Company’s debts do not trade in active markets, the Company calculated a base yield curve using a risk-free rate (a U.S. Treasury securities yield curve) plus a credit spread that is based on the following two factors: (i) an average of the Company’s own publicly-traded debt securities and (ii) the current market rates for U.S. Utility A debt securities. The Company used these yield curve assumptions to derive a base yield for the Level 2 and Level 3 securities. Additionally, the Company adjusted the base yield for specific features of the debt securities including call features, coupon tax treatment and collateral for the Level 3 instruments.

19

The carrying amounts, including fair value adjustments previously recognized in acquisition purchase accounting and a fair value adjustment related to the Company’s interest rate swap fair value hedge (which is classified as Level 2 in the fair value hierarchy), and fair values of the financial instruments were as follows:

	Carrying		At Fair Value as of June 30, 2017
	Amount		Level 1		Level 2		Level 3		Total
Preferred stock with mandatory redemption requirements	$	11	$	—	$	—	$	14	$	14
Long-term debt (excluding capital lease obligations)		6,333		4,007		1,348		1,847		7,202

Preferred stock with mandatory redemption requirements	$	12	$	—	$	—	$	15	$	15
Long-term debt (excluding capital lease obligations)		6,320		3,876		1,363		1,805		7,044

Recurring Fair Value Measurements

The following table presents assets and liabilities measured and recorded at fair value on a recurring basis and their level in the fair value hierarchy:

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 operations and maintenance projects. The proceeds of these financings are held in escrow until the designated expenditures are incurred. Long-term restricted funds of $1 and $4 were included in other long-term assets as of June 30, 2017 and December 31, 2016, respectively.

20

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.

Deposits—Deposits include escrow funds and certain other deposits held in trust. The Company includes cash deposits in other current assets.

Mark-to-market derivative asset and liability—The Company utilizes fixed-to-floating interest-rate swaps, typically designated as fair-value hedges, to achieve a targeted level of variable-rate debt as a percentage of total debt. The Company also employs derivative financial instruments in the form of variable-to-fixed interest rate swaps and forward starting interest rate swaps, classified as economic hedges and cash flow hedges, respectively, 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—Other investments primarily represent money market funds used for active employee benefits. The Company includes other investments in other current assets.

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. 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.

Note 12: Segment Information

The Company conducts its business primarily through one reportable segment, the Regulated Businesses segment. The Company also operates several businesses that provide a broad range of related and complementary water and wastewater services in four operating segments that individually do not meet the criteria of a reportable segment in accordance with GAAP. These four non-reportable operating segments are collectively presented as the Company’s “Market-Based Businesses”. “Other” includes corporate costs that are not allocated to the Company’s operating segments, eliminations of inter-segment transactions, fair value adjustments and associated income and deductions related to acquisitions that have not been allocated to the operating segments for evaluation of performance and allocation of resource purposes. The following tables include the Company’s summarized segment information:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read together with the unaudited consolidated financial statements and the notes thereto included elsewhere in this Form 10-Q. This discussion contains forward-looking statements that are based on management’s current expectations, estimates and projections about our business, operations and financial performance. The cautionary statements made in this Form 10-Q should be read as applying to all related forward-looking statements whenever they appear in this Form 10-Q. Our actual results may differ materially from those currently anticipated and expressed in such forward-looking statements as result of a number of factors, including those we discuss under “Forward-Looking Statements,” and elsewhere in this Form 10-Q.

General

Through its subsidiaries, American Water Works Company, Inc. (“American Water” or the “Company”) is the largest and most geographically diverse investor-owned publicly-traded water and wastewater utility company in the United States, as measured by both operating revenue and population served. Our primary business involves the ownership of utilities that provide water and wastewater services to residential, commercial, industrial and other customers, including sale for resale and public authority customers. Our utilities are generally subject to economic regulation by certain state utility commissions or other entities engaged in utility regulation. We report the results of our utilities in our Regulated Businesses segment. We also operate several businesses that provide a broad range of related and complementary water and wastewater services that are not subject to economic regulation by state utility commissions or other entities engaged in utility regulation. We present the results of these businesses as our “Market-Based Businesses.” For further description of our businesses, see Part I, Item 1—Business in our Form 10-K.

You should read the following discussion in conjunction with our Consolidated Financial Statements and related Notes included elsewhere in this Form 10-Q and in our Form 10-K.

Financial Results

Income attributable to common stockholders was $131 million, or $0.73 per diluted share, for three months ended June 30, 2017, a decrease of 5.2% over the same period in 2016. Net income from our Regulated Businesses segment increased 3.7% from infrastructure investment growth, acquisitions and organic growth. Offsetting this was lower net income in our Market-Based Businesses primarily due to lower capital upgrades in our Military Services Group compared to the same period in 2016, and lower net income at the Parent largely from a one-time, non-cash, cumulative tax adjustment from a legislative change adopted in New York during the second quarter, exempting water utilities from the manufacturers tax deduction.

Income attributable to common stockholders was$224 million, or $1.26 per diluted share, for the six months ended June 30, 2017, an increase of 2.4% over the same period in 2016. Net income from our Regulated Businesses segment increased 5.4% from infrastructure investment growth, acquisitions and organic growth. Net income from our Market-Based Businesses decreased primarily due to lower capital upgrades in our Military Services Group. Net income at the Parent also decreased primarily from the one-time, non-cash, cumulative tax adjustment discussed above.

See “Comparison of Consolidated Results of Operations” and “Segment Results of Operations” below for further discussion on the consolidated results of operations, as well as our business segments.

Focusing on Central Themes

For 2017, our focus continues to be anchored on our five central themes: 1) Safety, 2) Customers, 3) People, 4) Growth and 5) Technology and Operational Efficiency. We continue our focus on operating our business responsibly and managing our operating and capital costs in a manner that benefits our customers and produces long-term value for our stockholders. Additionally, we continue to execute on our ongoing strategy that ensures a safe workplace for our employees, emphasizes public safety for our customers and communities, and leverages our human resources, processes and technology innovation to make our business more effective and efficient. The progress that we have made during the first six months of 2017 with respect to growth and improvement in our operational efficiency ratio is described below.

23

Growth—Infrastructure improvements, acquisitions and strategic capital investments

During the first six months of 2017, we made capital investments of approximately $618 million, focused in two key areas:

• $576 million of which the majority was in our Regulated Businesses segment for infrastructure improvements; and

• $42 million to fund acquisitions in our Regulated Businesses segment, which added approximately 15,000 water and wastewater customers. This includes the acquisition on April 3, 2017, of all the outstanding capital stock of Shorelands Water Company, Inc. (“Shorelands”), for total consideration of $33 million in the form of 438,211 shares of our common stock.  Shorelands, which is now a part of our New Jersey subsidiary, provides water service to approximately 11,000 customers in Monmouth County, New Jersey.

For the full year of 2017, our capital investment, including regulated acquisitions, is expected to be in the range of $1.5 billion to $1.6 billion.

Included in this range is the asset purchase agreement signed by our Pennsylvania subsidiary to acquire substantially all of the wastewater collection and treatment system assets of the Municipal Authority of the City of McKeesport, Pennsylvania for approximately $162 million, subject to certain adjustments provided in the agreement. In connection with the execution of this agreement, $7 million in non-escrowed deposits have been made to the seller. The closing of this acquisition is subject to the satisfaction of various conditions and covenants, including obtaining the approval of the Pennsylvania Public Utility Commission. The system currently represents approximately 22,000 wastewater customers. We are expecting to close this acquisition by the first quarter of 2018.

Technology & Operational Efficiency—Continuing Improvement in Adjusted Operation and Maintenance (“O&M”) Efficiency Ratio for our Regulated Businesses

We continued to improve on our adjusted O&M efficiency ratio (a non-GAAP measure). Our adjusted O&M efficiency ratio for the twelve months ended June 30, 2017 was 34.5%, compared to 35.2% for the twelve months ended June 30, 2016. The improvement in this ratio for the twelve months ended June 30, 2017, as compared to the same period in 2016, was primarily attributable to an increase in regulated operating revenue.

Our adjusted O&M efficiency ratio is defined as our regulated operation and maintenance expenses divided by regulated operating revenues, where both operation and maintenance expenses and operating revenues were adjusted to eliminate purchased water expense. Additionally, from the operation and maintenance expenses, we excluded the allocable portion of non-operation and maintenance support services cost, mainly depreciation and general taxes that are reflected in our Regulated Businesses segment as operation and maintenance expenses but for consolidated financial reporting purposes are categorized within other line items in the accompanying Consolidated Statements of Operations. In addition to the standard adjustments to our adjusted O&M efficiency ratio for the twelve months ended June 30, 2017, we have also excluded from operation and maintenance expenses, the impact from the binding global agreement in principle related to the Freedom Industries chemical spill in West Virginia. We excluded all the above items from the calculation as we believe such items are not reflective of management’s ability to increase efficiency of our regulated operations.

We evaluate our operating performance using this measure because we believe it is a direct measure of the improvement to the efficiency of our regulated operations. This information is intended to enhance an investor’s overall understanding of our operating performance. Our adjusted O&M efficiency ratio is not a GAAP financial measure and may not be comparable to other companies’ operating measures and should not be used in place of the GAAP information provided elsewhere in this report.

24

The following table provides the calculation and reconciliation that compares operation and maintenance expenses and operating revenues, as determined in accordance with GAAP, to those amounts utilized in the calculation of our adjusted O&M efficiency ratio for the twelve months ended June 30, 2017, as compared to the same period in 2016:

Pending and Filed Rate Cases

On April 3, 2017, our California subsidiary filed a cost of capital application requesting a cost of capital of 8.49%, compared to 8.41% currently authorized. The results of this proceeding will not become effective until January 2018.

On April 28, 2017, our Pennsylvania subsidiary filed a general rate case requesting $108 million in additional annualized water and wastewater revenues.

On May 15, 2017, our Missouri subsidiary filed for additional annualized revenues from an infrastructure surcharge in the amount of $5 million.

On June 15, 2017, our West Virginia subsidiary filed for additional annualized revenues from an infrastructure surcharge in the amount of $3 million.

On June 30, 2017, our Missouri subsidiary filed a general rate case requesting $84 million in additional annualized water and wastewater revenues.  

In addition to the filings discussed above, we are awaiting a final general rate case order in our California subsidiary, requesting additional annualized revenue of $35 million and step rate and attrition rate increases of $8 million in both 2019 and 2020. There is no assurance that all or any portion of these requests will be granted.

Other Tax Matters

On April 11, 2017, the State of New York enacted legislation that increased the state income tax rate on our taxable income attributable to New York. This legislation eliminated the production of water as a qualified manufacturing activity in New York, which effectively increased the state income tax rate in New York. As a result of the legislative change, we were required to re-measure our cumulative deferred tax balances using the higher state income tax rate in the second quarter of 2017. This change in legislation was the primary cause of an increase to our unitary deferred tax liability of $11 million. The portion of this increase related to our New York subsidiary calculated on a stand-alone basis was $7 million, and was offset by a regulatory asset, as we believe it is probable of recovery in future rates. The remaining increase in the deferred tax liability was calculated through state tax apportionment rates and recorded at the consolidated level, resulting in a non-cash, cumulative charge to earnings of $4 million during the second quarter of 2017.

On July 7, 2017, the State of Illinois enacted legislation that increased, effective July 1, 2017, the state income tax rate on our taxable income attributable to Illinois from 7.75% to 9.5%. As a result of the legislative change, we will be required to re-measure our cumulative deferred tax balances using the higher state income tax rate in the third quarter of 2017. This re-measurement is expected to increase our deferred tax liability by $6 million. The portion of this increase related to our Illinois subsidiary calculated on a stand-alone basis and is estimated to be $3 million, and is expected to be offset by a regulatory asset, as we believe it is probable of recovery in future rates. The remaining increase in the deferred tax liability will be calculated through state tax apportionment rates and recorded at the consolidated level. We expect this will result in a non-cash, cumulative charge to earnings of $3 million during the third quarter of 2017.

During the second quarter of 2017, we were notified by the assessor for St. Louis County, Missouri, that it was changing its long standing practice of valuing regulated water and wastewater property located in the County using a seven-year life, and instead intends to use a twenty-year life for a substantial portion of this property. During the second quarter of 2017, we were also notified by the assessor for Platte County, Missouri, that it intended to change its long standing practice of valuing regulated water and wastewater property located in the County using a twenty-seven-year life, and instead intends to use a fifty-year life for a substantial portion of this property. These changes in practice and the resulting valuations as assessed by the respective County, will increase our property tax obligation beginning in 2017. We are currently evaluating if we intend to appeal these assessments once received. We have asked the Missouri regulator for an accounting recovery mechanism that would allow deferral of any increase in tax resulting from these changes in long standing practice, and we believe these increases are recoverable through future customer rates. As a result, during the second quarter of 2017, we recorded the additional estimated increase in property tax obligation of $2 million, with an offset to a regulatory asset.

Comparison of Consolidated Results of Operations

Operating revenues. For the three months ended June 30, 2017, operating revenues increased primarily due to a:

• $30 million increase in our Regulated Businesses segment largely due to authorized rate increases to fund infrastructure investment growth, acquisitions and organic growth, partially offset by lower demand in 2017 and warmer weather in the second quarter of 2016; partially offset by

• $12 million decrease in our Market-Based Businesses principally due to lower capital upgrades in our Military Services Group in 2017 as compared to 2016, largely attributable to reduced military base budgets and the completion of a large project in mid-2016 at Fort Polk. Partially offsetting this decrease were incremental revenues from our Homeowner Services Group from customer additions and price increases for certain existing customers.

For the six months ended June 30, 2017, operating revenues increased primarily due to a:

• $55 million increase in our Regulated Businesses segment largely due to authorized rate increases to fund infrastructure investment growth, acquisitions and organic growth, partially offset by lower demand in 2017 and warmer weather in the second quarter of 2016; partially offset by

• $23 million decrease in our Market-Based Businesses principally due to lower capital upgrades in our Military Services Group in 2017 as compared to 2016, largely attributable to reduced military base budgets and the completion of a large project in mid-2016 at Fort Polk. Partially offsetting this decrease were incremental revenues from our Homeowner Services Group from customer additions and price increases for certain existing customers.

Operation and maintenance. For the three months ended June 30, 2017, operation and maintenance expense decreased primarily due to a:

• $10 million decrease in our Market-Based Businesses principally due to lower capital upgrades in our Military Services Group, as discussed above, partially offset by higher expenses in our Homeowner Services Group from contract growth and incremental claims expense; and

• $7 million increase in our Regulated Businesses segment largely due to higher production costs and an increase in customer uncollectible expense.

27

Operation and maintenance.For the six months ended June 30, 2017, operation and maintenance expense decreased primarily due to a:

• $21 million decrease in our Market-Based Businesses principally due to lower capital upgrades in our Military Services Group, as discussed above; and other cost savings being driven across the business.  Partially offsetting this decrease were higher expenses in our Homeowner Services Group from contract growth and incremental claims expense; and

• $7 million increase in our Regulated Businesses segment largely due to higher production costs, as well as an increase in materials and supplies, largely due to timing.

Depreciation and amortization. For the three and six months ended June 30, 2017, depreciation and amortization expense increased primarily due to additional utility plant placed in service.

Other income (expenses).For the three and six months ended June 30, 2017, other expenses increased primarily due to an increase in long-term interest expense from the issuance of incremental long-term debt in the fourth quarter of 2016, as well as an increase in short-term interest expense resulting from higher levels of short-term borrowings, coupled with an increase in the average short-term borrowing rates. Approximately $3 million and $5 million of the increase in interest is attributed to our Regulated Businesses segment for the three and six months ended June 30, 2017, respectively. Additionally, the prior year’s results included a settlement of a contract dispute in our Market-Based Businesses.

Provision for income taxes. For the three and six months ended June 30, 2017, our provision for income taxes increased primarily due to a one-time, non-cash cumulative adjustment of $4 million, as a result of legislation enacted in the State of New York, eliminating the production of water as a manufacturing activity, effectively increasing the income tax rate in the state.

Segment Results of Operations

Our segments are determined based on how we assess performance and allocate our resources. We evaluate the performance of our segments and allocate resources based on several factors, with the primary measure being income from continuing operations.

We conduct our business primarily through one reportable segment, our Regulated Businesses segment. We also operate several businesses that provide a broad range of related and complementary water and wastewater services in four operating segments that individually do not meet the criteria of a reportable segment in accordance with GAAP. These four non-reportable operating segments are collectively presented as our “Market-Based Businesses”, which is consistent with how management assesses the results of our businesses.

For the three months ended June 30, 2017, operating revenues increased primarily due to a:

• $23 million increase due to authorized rate increases and infrastructure surcharges to fund infrastructure investment growth in various states; and

• $12 million increase due to higher demand relating to our water and wastewater acquisitions, as well as organic growth in existing systems; partially offset by a

• $7 million decrease due to lower demand, excluding the impact of completed acquisitions, when compared to the same period in 2016 and warmer weather in the second quarter of 2016.

For the six months ended June 30, 2017, operating revenues increased primarily due to a:

• $47 million increase due to authorized rate increases and infrastructure surcharges to fund infrastructure investment growth in various states; and

• $19 million increase due to higher demand relating to our water and wastewater acquisitions, as well as organic growth in existing systems; partially offset by a

• $15 million decrease due to lower demand, excluding the impact of completed acquisitions, when compared to the same period in 2016 and warmer weather in the second quarter of 2016.

For the three months ended June 30, 2017, operation and maintenance expense increased primarily due to a:

• $3 million increase in production costs principally due to purchased water price and usage increases in our California subsidiary, as well as increased waste disposal and fuel and power costs, mainly attributable to the acquisition of two wastewater systems in our Pennsylvania subsidiary in the fourth quarter of 2016; and

• $3 million increase in customer uncollectible expense.

For the six months ended June 30, 2017, operation and maintenance expense increased primarily due to a:

• $3 million increase in production costs principally due to purchased water price and usage increases in our California subsidiary, as well as increased waste disposal and fuel and power costs, mainly from the acquisition of two wastewater systems by our Pennsylvania subsidiary in the fourth quarter of 2016; and

• $4 million increase in maintenance materials and supplies largely due to timing of activities.

Operating expenses, net. For the three and six months ended June 30, 2017, operating expenses, net increased primarily due to the increase in operating and maintenance expense as explained above, and higher depreciation and amortization expense of $10 million and $19 million, respectively.  This increase in depreciation and amortization expense was primarily due to additional utility plant placed in service. For the six months ended June 30, 2017, operating expenses, net, also increased by an increase in general taxes of $3 million, primarily due to higher gross receipts taxes in New Jersey and higher property taxes in 2017 driven by investment growth.

Market-Based Businesses

Operating revenues. For the three months ended June 30, 2017, operating revenues decreased primarily due to a:

• $20 million decrease in our Military Services Group principally due to lower capital upgrades in 2017 as compared to 2016, largely attributable to reduced military base budgets and the completion of a large project in mid-2016 at Fort Polk; partially offset by a

• $4 million increase in our Homeowner Services Group from customer additions and price increases for certain existing customers.

For the six months ended June 30, 2017, operating revenues decreased primarily due to a:

• $37 million decrease in our Military Services Group principally due to lower capital upgrades in 2017 as compared to 2016, largely attributable to reduced military base budgets and the completion of a large project in mid-2016 at Fort Polk; partially offset by a

• $10 million increase in our Homeowner Services Group from customer additions and price increases for certain existing customers.

For the three months ended June 30, 2017, operation and maintenance expense decreased primarily due to a:

• $15 million decrease in operating supplies and services principally due to lower capital upgrades in 2017 as compared to 2016, in our Military Services Group, as discussed above; partially offset by

• $4 million increase in maintenance services and supplies primarily due to contract growth and incremental claims activity in our Homeowner Services Group.

For the six months ended June 30, 2017, operation and maintenance expense decreased primarily due to a:

• $30 million decrease in operating supplies and services principally due to lower capital upgrades in 2017 as compared to 2016, in our Military Services Group, as discussed above; partially offset by

• $7 million increase in maintenance services and supplies primarily due to contract growth and incremental claims activity in our Homeowner Services Group.

Liquidity and Capital Resources

For a general overview of our sources and uses of capital resources, see the introductory discussion in Part II, Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources contained in our Form 10-K.

We fund liquidity needs for capital investment, working capital and other financial commitments through cash flows from operations, public and private debt offerings, commercial paper markets and, if and to the extent necessary, borrowing under the American Water Capital Corp. (“AWCC”) revolving credit facility. The revolving credit facility provides $1.75 billion in aggregate total commitments from a diversified group of financial institutions with an expiration date of June 2020 (subject to extension by us for up to two one-year periods).We regularly evaluate the capital markets and closely monitor the financial condition of the financial institutions with contractual commitments in our revolving credit facility.

In order to meet our short-term liquidity needs, we, through AWCC, our wholly owned financing subsidiary, issue commercial paper, which is supported by our revolving credit facility. As of June 30, 2017, AWCC had no outstanding borrowings and $86 million of outstanding letters of credit under the revolving credit facility, with $1.66 billion available to fulfill our short-term liquidity needs and to issue letters of credit. As of June 30, 2017, the revolving credit facility supported $1.1 billion in outstanding commercial paper. We believe that our ability to access the capital markets, our revolving credit facility and our cash flows from operations will generate sufficient cash to fund our short-term requirements. However, we can provide no assurances that the lenders will meet their existing commitments to AWCC under the credit facility or that we will be able to access the commercial paper or loan markets in the future on terms acceptable to us or at all.

31

On February 8, 2017, we entered into a forward swap agreement with a notional amount of $100 million to reduce interest rate exposure for a portion of the expected refinancing of our 5.62% fixed-rate long-term debt maturing in December 2018. This forward starting swap agreement terminates in November 2018 and has an average fixed rate of 2.67%. During the three and six months ended June 30, 2017, the fair value of our five forward starting swaps decreased by $8 million and $3 million, respectively, due to lower net forward interest rates. Changes in the fair value of the forward starting swaps will be recognized in accumulated other comprehensive loss until the agreements terminate. See Note 6—Long-Term Debt in the Notes to Consolidated Financial Statements for further information.

Cash Flows Provided by Operating Activities

Cash flows provided by operating activities primarily result from the sale of water and wastewater services and, due to the seasonality of demand, are generally greater during the third quarter of each fiscal year. The following table provides a summary of the major items affecting cash flows provided by our operating activities:

	For the Six Months Ended June 30,
	2017			2016
(In millions)
Net income	$	224		$	219
Add (less):
Non-cash activities (a)		375			388
Changes in working capital (b)		(52	)		(43	)
Pension and postretirement healthcare contributions		(23	)		(28	)
Net cash flows provided by operations	$	524		$	536

(a) Includes depreciation and amortization, deferred income taxes and amortization of deferred investment tax credits, provision for losses on accounts receivable, gain on asset dispositions and purchases, pension and non-pension postretirement benefits expense and other non-cash, net. Details of each component can be found in the Consolidated Statements of Cash Flows.

(b) Changes in working capital include changes to receivables and unbilled revenues, accounts payable and accrued liabilities, and other current assets and liabilities, net.

For the six months ended June 30, 2017, decrease in cash flows from operating activities, as compared to the same period in 2016, is primarily due to the decrease in working capital primarily driven by the result of the lower capital upgrades in Military Services group and timing. These decreases were partially offset by increased net income after non-cash adjustments. The main factors contributing to the net income increase are described in this section under “Comparison of Consolidated Results of Operations” and included higher operating revenue and lower operation and maintenance expense, mainly driven by the lower capital upgrade work in the Military Services Group.

Cash Flows Used in Investing Activities

The following table provides information regarding cash flows used in our investing activities:

	For the Six Months Ended June 30,
	2017			2016
(In millions)
Net capital expenditures	$	(602	)	$	(597	)
Acquisitions		(9	)		(24	)
Other investing activities, net (a)		(29	)		(44	)
Net cash flows used in investing activities	$	(640	)	$	(665	)

(a) Includes removal costs from property, plant and equipment retirements, net, proceeds from sale of assets and net funds restricted.

For the six months ended June 30, 2017, cash used in investing activities decreased primarily due to the timing of payments for the capital expenditures and acquisitions, and decreased removal costs from property, plant and equipment retirements. We expect investments of approximately $1.5 billion to $1.6 billion in 2017 for capital expenditures and acquisitions. We have also begun the construction of our new corporate headquarters building in Camden, New Jersey. The cost of construction is currently estimated to be up to $165 million, exclusive of any tax incentives, of which $70 million is expected to be incurred in 2017.

32

Cash Flows Provided by Financing Activities

The following table provides information regarding cash flows provided by our financing activities:

	For the Six Months Ended June 30,
	2017			2016
(In millions)
Proceeds from long-term debt	$	20		$	2
Repayments of long-term debt		(6	)		(13	)
Net proceeds from short-term borrowings		268			321
Dividends paid		(141	)		(127	)
Anti-dilutive stock repurchases		(54	)		(65	)
Other financing activities, net (a)		18			18
Net cash flows provided by financing activities	$	105		$	136

(a) Includes proceeds from issuances of common stock under various employee stock plans and our dividend reinvestment plan, advances and contributions for construction, net of refunds, taxes paid related to employee stock plans and debt issuance costs.

For the six months ended June 30, 2017, the decrease in cash flows provided by financing activities, as compared to the same period in 2016, is primarily due to a decrease in proceeds from short-term borrowings in 2017 compared to 2016 related to incremental short-term borrowings in 2016 to fund a portion of the capital expenditures and acquisitions, partially offset by higher proceeds from long-term debt during 2017.

Credit Facilities and Short-Term Debt

The following table summarizes information regarding our aggregate credit facility commitments, letter of credit sub-limits and available funds under those revolving credit facilities, as well as outstanding amounts of commercial paper and outstanding borrowings under the respective facilities as of June 30, 2017:

	Credit Facilities Commitment(a)		AvailableCredit Facility Capacity (a)		Letter of Credit Sublimit		AvailableLetter of Credit Capacity		Commercial Paper Limit		Available Commercial Paper Capacity
(In millions)
June 30, 2017	$	1,762	$	1,672	$	150	$	64	$	1,600	$	483

(a) Includes amounts related to the revolving credit facility of Keystone Clearwater Solutions, LLC (“Keystone”), our water management solutions subsidiary. As of June 30, 2017, the total commitment under the Keystone revolving credit facility was $12 million, of which $8 million was available for borrowing, subject to compliance with a collateral base calculation.

The weighted-average interest rate on AWCC short-term borrowings for three months ended June 30, 2017 and 2016 was approximately 1.24% and 0.76%, respectively. The weighted-average interest rate on AWCC short-term borrowings for the six months ended June 30, 2017 and 2016 was approximately 1.14% and 0.75%, respectively.

Capital Structure

The following table indicates the percentage of our capitalization represented by the components of our capital structure as of the dates set forth below:

	June 30, 2017			December 31, 2016
Total common stockholders' equity		41.9	%		42.1	%
Long-term debt and redeemable preferred stock at redemption value		44.1	%		46.4	%
Short-term debt and current portion of long-term debt		14.0	%		11.5	%
		100	%		100	%

33

Debt Covenants  

Our debt agreements contain financial and non-financial covenants. To the extent that we are not in compliance with these covenants, an event of default may occur under one or more debt agreements and we or our subsidiaries may be restricted in our ability to pay dividends, issue new debt or access our revolving credit facility. Our long-term debt indentures contain a number of covenants that, among other things, prohibit or restrict the Company from issuing debt secured by the Company’s assets, subject to certain exceptions. Our failure to comply with any of these covenants could accelerate repayment obligations.

Covenants in certain long-term notes and the revolving credit facility require us to maintain a ratio of consolidated debt to consolidated capitalization (as defined in the relevant documents) of not more than 0.70 to 1.00. On June 30, 2017, our ratio was 0.58 to 1.00 and therefore we were in compliance with the covenants.

Security Ratings

Our access to the capital markets, including the commercial paper market, and respective financing costs in those markets, may be directly affected by our securities ratings. We primarily access the debt capital markets, including the commercial paper market, through AWCC. However, we have also issued debt through our regulated subsidiaries, primarily in the form of tax exempt securities or borrowings under state revolving funds, to lower our overall cost of debt.

Our long-term and short-term credit ratings as of June 30, 2017:

Securities	Moody's Investors Service	Standard & Poor's Ratings Service
Senior unsecured debt	A3	A
Commercial paper	P-2	A-1

A security rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency, and each rating should be evaluated independently of any other rating. Security ratings are highly dependent upon our ability to generate cash flows in an amount sufficient to service our debt and meet our investment plans. We can provide no assurances that our ability to generate cash flows is sufficient to maintain our existing ratings. None of our borrowings are subject to default or prepayment as a result of a downgrading of these security ratings, although such a downgrading could increase fees and interest charges under our credit facility.

Dividends

On June 1, 2017, we paid a cash dividend of $0.415 per share to our stockholders of record as of May 5, 2017.

On July 28, 2017, our Board of Directors declared a quarterly cash dividend payment of $0.415 per share payable on September 1, 2017 to stockholders of record as of August 9, 2017. Future dividends, when and as declared at the discretion of the Board of Directors, will be dependent upon future earnings and cash flows, compliance with various regulatory, financial and legal requirements, and other factors. See Part II, Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Dividends in our Form 10-K for more information regarding restrictions on the payment of dividends on our common stock.

Application of Critical Accounting Policies and Estimates

Our financial condition, results of operations and cash flows are impacted by the methods, assumptions and estimates used in the application of critical accounting policies. See Part II, Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates in our Form 10-K for a discussion of our critical accounting policies.

Recent Accounting Standards

See Note 2—New Accounting Standards to the Notes to Consolidated Financial Statements included in Part I, Item 1—Consolidated Financial Statements of this Quarterly Report on Form 10-Q for a description of new accounting standards recently adopted or pending adoption.

34

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are subject to market risks in the normal course of business, including changes in interest rates and equity prices. For a discussion of our exposure to market risk, refer to Part II, Item 7A—Quantitative and Qualitative Disclosures about Market Risk contained in our Form 10-K. Except as described below, there have been no significant changes to our exposure to market risk since December 31, 2016.

On February 8, 2017, we entered into a forward starting swap agreement with a notional amount of $100 million to reduce interest rate exposure on debt expected to be issued in 2018. This forward starting swap agreement terminates in November 2018 and has an average fixed rate of 2.67%. A hypothetical one hundred basis point change in the forward starting swap rates would have resulted in a $21 million increase or decrease in fair value for the six months ended June 30, 2017.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

American Water maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Our management, including the Chief Executive Officer and the Chief Financial Officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of June 30, 2017.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2017, our disclosure controls and procedures were effective at a reasonable level of assurance.

Changes in Internal Control over Financial Reporting

We concluded that there have been no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2017, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act).

Alternative Water Supply in Lieu of Carmel River Diversions

On November 29, 2016, the Water Ratepayers Association of the Monterey Peninsula, a citizens’ advocacy group, filed an action in Sacramento County Superior Court against the SWRCB and its board members, and naming Cal Am as the real party in interest, seeking to reverse the extension of the 2009 Order, to reverse the designation by the CPUC of Cal Am as the public utility water provider to the Monterey Peninsula, and to appoint a receiver to oversee Cal Am’s compliance with the 2009 Order, with ultimate transfer to a public entity. In May 2017, Cal Am and the SWRCB filed demurrers to the action, and on June 12, 2017, the court entered an order sustaining those demurrers and dismissing the action with prejudice.

Trial has been set for June 18, 2018 in the consolidated action in San Francisco County Superior Court associated with the failure of the RDP.

Monterey Peninsula Water Supply Project

On January 12, 2017, the CPUC issued a Draft Environmental Impact Report/Environmental Impact Statement. The comment period for this report expired March 29, 2017 and a final report is expected to be issued in the fourth quarter of 2017 or the first quarter of 2018.

Trial has been set for August 30, 2017 for all matters raised in MCWD’s November 2015 challenge to the amendment of Cal Am’s coastal development permits for the test slant well, other than claims that had been denied by the court in September 2016.

On July 13, 2017, the Coastal Commission adopted a consent agreement and cease and desist order requiring sand mining operations on the property on which intake wells will be located to cease by the end of 2020 and the property to be sold to either a non-profit or governmental entity. The consent agreement strictly limits future use of the property but preserves Cal Am’s existing property rights and allows uses consistent with existing easements and other rights of record. If the test slant well is to remain at the site and be used as part of the Water Supply Project, as currently proposed, Cal Am will likely need to seek an amendment and extension of its coastal development permit to allow the test slant well to remain and be maintained in the interim period until the Water Supply Project is operational.

West Virginia Elk River Freedom Industries Chemical Spill

Background

Currently, 74 cases remain pending with respect to this matter in the U.S. District Court for the Southern District of West Virginia or the West Virginia Mass Litigation Panel.

On July 7, 2016, the court in the Federal action scheduled trial to begin on October 25, 2016, but the court has granted several continuances of the trial, which is currently postponed indefinitely in light of the proposed settlement agreement discussed below. The Mass Litigation Panel has also stayed its proceedings until October 23, 2017.

WVAWC Binding Global Agreement in Principle to Settle Claims

On April 27, 2017, the parties filed with the court in the Federal action a proposed settlement agreement providing details of the terms of the Settlement consistent with those described above. The parties also requested that the court in the Federal action grant preliminary approval of the Settlement.

36

On July 6, 2017, the court in the Federal action issued an opinion denying without prejudice the joint motion for preliminary approval of the Settlement. The court in the Federal action found the overall amount and structure of the Settlement to be fair, adequate and reasonable, but it declined to preliminarily approve the Settlement on several grounds, including the fairness of the methodology for allocating payments among members of the business class, the nature of the claims appeal process and the timing of the payment of claims that are subject to appeal, and the fairness of setting of fixed payments for the medical claims class. The American Water Defendants intend to work with the Plaintiffs to propose acceptable alternative provisions to the Settlement Agreement to satisfy the concerns of the court in the Federal action. If and when preliminary approval of the Settlement is obtained, notice of the terms of the Settlement would then be provided to members of the settlement class. Following the notice period, the court in the Federal action would hold a fairness hearing to consider final approval of the Settlement.

Other Related Proceedings

On April 4, 2017, the CSB indicated that the implementation by the Company of source water protection activities resolved the first two parts of the CSB’s recommendation. The CSB also noted that compliance by the Company with the third part of its recommendation is ongoing and that closure of this part is contingent upon completion of updated contingency planning for the Company’s water utilities outside of West Virginia. In light of public response to its original September 2016 investigation report, on May 11, 2017, the CSB issued a new version of this report. The primary substantive change addressed CSB’s factual evaluation of the duration and volume of contamination from the leaking tank, decreasing its estimate of the leak time but increasing the volume estimate by 10%. No substantive changes were made to the conclusions and recommendations in the original report.

On June 15, 2017, the PSC entered an order accepting the joint stipulation that had been filed by the parties in January 2017 as a reasonable basis for resolving the General Investigation and removing the proceeding from the docket. The PSC’s order did not require WVAWC to take any further action with respect to the matters covered by the General Investigation. The PSC order concludes the General Investigation.

On March 16, 2017, the Lincoln County (West Virginia) Commission (the “LCC”) passed a county ordinance entitled the “Lincoln County, WV Comprehensive Public Nuisance Investigation and Abatement Ordinance.” The ordinance establishes a mechanism that Lincoln County believes will allow it to pursue criminal or civil proceedings for the “public nuisance” it alleges was caused by the Freedom Industries chemical spill. On April 20, 2017, the LCC filed a complaint in Lincoln County state court against WVAWC and certain other defendants not affiliated with the Company, alleging that the Freedom Industries chemical spill caused a public nuisance in Lincoln County. The complaint seeks an injunction against WVAWC that would require the creation of various databases and public repositories of documents related to this chemical spill, as well as further study and risk assessments regarding the alleged exposure by Lincoln County residents to the released chemicals. On June 12, 2017, the Mass Litigation Panel entered an order granting a motion to transfer this case to its jurisdiction and stayed the case consistent with the existing stay order. WVAWC believes that this lawsuit is without merit and intends to vigorously contest the claims and allegations raised in the complaint.

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 WVAWC’s West Relay pumping station located in the City of Dunbar. The failure of the main caused water outages and low pressure to 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 completed safely on June 30, 2015. Water service was fully restored on July 1, 2015 to all customers affected by this event.

On June 2, 2017, a class action complaint was filed in West Virginia Circuit Court in Kanawha County against WVAWC on behalf of a purported 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 plaintiff seeks 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.

The Company and WVAWC believe that WVAWC has valid, meritorious defenses to the claims raised in this class action complaint. WVAWC intends to vigorously defend itself against these allegations. While WVAWC and the Company are unable to predict the outcome of this matter, an adverse outcome could have a material adverse effect on the Company’s financial condition, results of operations, cash flows, liquidity and/or reputation.

Contract Operations Group -- East Palo Alto Water System Voluntary Report

On April 10, 2017, American Water Enterprises, Inc. (“AWE”), a wholly owned subsidiary of the Company and the parent entity of the Company’s Contract Operations Group, voluntarily reported to the Division of Drinking Water of the SWRCB potential violations of the California Safe Drinking Water Act (the “CSDWA”) in connection with AWE’s operation of the City of East Palo Alto’s water distribution system. Upon the resignation of the system’s general manager in March 2017, AWE discovered that it may have operated the system without a properly certified operator for two years, the triennial Lead and Copper Rule sampling was not completed, and the 2015 Consumer Confidence Report improperly reported data for lead and copper samples from the system’s upstream water provider. Promptly after discovering these issues, AWE engaged an outside law firm to conduct an internal investigation and has reported the results of that investigation to the SWRCB.

On June 15, 2017, the SWRCB issued to AWE a citation that requires AWE to, among other things:  comply with regulations related to water operator certifications, lead and copper tap sampling requirements and the publishing of a Consumer Confidence Report; provide public notification of the Lead and Copper Rule violation; and prepare a corrective action plan to evaluate the causes leading to these incidents and measures to be taken to prevent reoccurrence of future incidents. The citation does not impose on AWE any monetary penalties, but the SWRCB reserved the right to take additional enforcement action. Proven violations of the CSDWA may result in civil and criminal penalties. On July 21, 2017, AWE submitted its corrective action plan to the SWRCB. AWE is cooperating fully with the SWRCB, the City of East Palo Alto and other authorities to resolve these issues.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In February 2015, the Board of Directors authorized an anti-dilutive stock repurchase program to mitigate the dilutive effect of shares issued through the Company’s dividend reinvestment, employee stock purchase and executive compensation activities. The program allows the Company to purchase up to 10 million shares of its outstanding common stock over an unrestricted period of time in the open market or through privately negotiated transactions. The program is conducted in accordance with Rule 10b-18 of the Exchange Act, and, to facilitate these repurchases, the Company enters into Rule 10b5-1 stock repurchase plans with a third-party broker, which allow the Company to repurchase shares of its common stock at times when it otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. Subject to applicable regulations, the Company may elect to amend or cancel the program or the stock repurchase parameters at its discretion to manage dilution.

The Company did not repurchase shares of common stock during three months ended June 30, 2017. From April 1, 2015, the date repurchases under the anti-dilutive stock repurchase program commenced, through June 30, 2017, the Company repurchased an aggregate of 3,950,000 shares of common stock under the program, leaving an aggregate of 6,050,000 shares available for repurchase under this program.

On April 3, 2017, the Company issued 438,211 shares of its common stock as consideration for the acquisition of all of the issued and outstanding shares of Shorelands in a transaction not involving a public offering of securities. The transaction was exempt from registration under the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof. The shares of Company common stock were issued to or for the benefit of 10 individuals who were the owners of the common stock of Shorelands.

The purpose of the American Water Works Company, Inc. 2017 Omnibus Equity Compensation Plan (the “Plan”) is to provide (i) designated employees of American Water Works Company, Inc. (the “Company”) and its subsidiaries and (ii) non-employee members of the board of directors of the Company (the “Board”) with the opportunity to receive grants of stock options, stock units, stock awards, stock appreciation rights and other stock-based awards. The Company believes that the Plan will encourage Participants (as defined herein) to contribute materially to the financial and operational success, and growth, of the Company, and will align the economic interests of Participants with those of its stockholders and customers.

2. Definitions

(ii) The consummation of (A) a merger or consolidation of the Company with another corporation where the stockholders of the Company, immediately prior to the merger or consolidation, will not beneficially own, immediately after the merger or consolidation,

shares entitling such stockholders to more than 50% of all votes to which all stockholders of the surviving corporation would be entitled in the election of directors, or (B) a sale or other disposition of all or substantially all of the assets of the Company; or

(iii) During any period of 12 consecutive months commencing on or after the Effective Date while the Plan is in effect, directors are elected such that a majority of the members of the Board are individuals who shall not have been members of the Board at the beginning of such 12-month period, except (x) in the case of a director’s death or (y) the election or nomination for election of each new director who was not a director at the beginning of such 12-month period where such election was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of such period.

(i) “Employee” means an employee of the Employer (including an officer or director who is also an employee), but excluding any person who is classified by the Employer as a “contractor” or “consultant,” no matter how characterized by the Internal Revenue Service, other governmental agency or a court. Any change of characterization of an individual by the Internal Revenue Service or any court or government agency shall have no effect upon the classification of an individual as an Employee for purposes of this Plan, unless the Committee determines otherwise.

(j) “Employer” means the Company and its subsidiaries.

(k) “Exchange Act” means the Securities Exchange Act of 1934, as amended.

(l) “Exercise Price” means the per share price at which shares of Company Stock may be purchased under an Option, as designated by the Committee.

The Plan shall be administered and interpreted by a committee consisting of members of the Board, which shall be appointed by the Board (the “Committee”).  The Committee shall consist of two or more persons who are “outside directors” as defined under section 162(m) of the Code, and related Treasury regulations, “non-employee directors” as defined under Rule 16b-3 under the Exchange Act, and “independent directors” as determined in accordance with the independence standards established by the stock exchange on which the Common Stock is at the time primarily traded.  However, except with respect to Grants described in Section 12 hereof, the Board may ratify or approve any Grants as it deems appropriate, and the Board shall approve and administer all Grants made to Non-Employee Directors.  The Committee may delegate authority to one or more subcommittees or the Chief Executive Officer of the Company, as it deems appropriate; provided, however, that any delegation to the Chief Executive Officer (i) shall only apply to Participants who are not subject to Section 16 of the Exchange Act and who are not “covered employees” within the meaning of section 162(m) of the Code; (ii) must include a limitation as to the amount of Grants that may be awarded during the period of the delegation, (iii) may contain guidelines not inconsistent with the Plan as to the determination of the Exercise Price for an Option or the price of other Grants, and any criteria for vesting or exercisability of such Grants; (iv) may be revoked or amended at any time but such action shall not invalidate any prior actions of the Committee’s delegation that were consistent with the terms of the Plan and of such delegation prior to amendment or revocation; and (v) shall be subject to such other terms and conditions as prescribed by the Committee. To the extent the Board, a subcommittee or the Chief Executive Officer performs these administration duties under the Plan, references in the Plan to the “Committee” shall be deemed to refer to the Board, such subcommittee or the Chief Executive Officer.

(b) Committee Authority. The Committee shall have the sole authority to (i) determine the Participants to whom Grants shall be made under the Plan, (ii) determine the type, size and terms and conditions of the Grants to be made to each such Participant, (iii) determine the time when the Grants will be made and the duration of any applicable exercise or restriction period, including the criteria for exercisability or vesting and the acceleration of exercisability or vesting, (iv) amend the terms and conditions of any previously issued Grant, subject to the provisions of Section 18 below, and (v) deal with any other matters arising under the Plan.

(c) Committee Determinations. Subject to Section 3(d), the Committee shall have full power and express discretionary authority to administer and interpret the Plan, to make factual determinations and to adopt or amend such rules, regulations, agreements and instruments for implementing the Plan and for the conduct of its business as it deems necessary or advisable, in its sole discretion. The Committee’s interpretations of the Plan and all determinations made by the Committee pursuant to the powers vested in it hereunder shall be conclusive and binding on all persons having any interest in the Plan or in Grants hereunder. All powers of the Committee shall be executed in its sole discretion, in the best interest of the Company, not as a fiduciary, and in keeping with the objectives of the Plan and need not be uniform as to similarly situated Participants.

(d) Delegation of Administration. The Committee may delegate certain administrative or ministerial matters under the Plan to one or more officer or officers of the Company (or their designees) as determined in the Committee’s discretion, and such persons may have the authority to (i) prepare, distribute and, if required, execute Grant Agreements in accordance with the Committee’s determinations, (ii) maintain or cause to be maintained (including through a third party administrator) records relating to the granting, vesting, exercise, forfeiture or expiration of Grants, (iii) process or oversee the issuance of, or cause to be issued, shares or cash upon the exercise, vesting and/or settlement of a Grant, and (iv) take such other administrative or ministerial actions (other than with respect to the making, modification or termination of, any Grant), or cause such actions to be taken, as the Committee may authorize.  Any delegation by the Committee pursuant to this subsection shall be subject to and limited by applicable law or regulation, including without limitation the rules and regulations of the Exchange Act, the Code and the securities exchange on which the Common Stock is then listed.

4. Grants

(a) Grants under the Plan may consist of Options as described in Section 7, Stock Units as described in Section 8, Stock Awards as described in Section 9, SARs as described in Section 10 and Other Stock-Based Awards as described in Section 11. All Grants shall be subject to such terms and conditions as the Committee deems appropriate and as are specified in writing by the Committee to the Participant in the Grant Agreement.

(b) All Grants shall be made conditional upon the Participant’s acknowledgement, in writing or by acceptance of the Grant, that all decisions and determinations of the Committee shall be final and binding on the Participant, his or her beneficiaries and any other person having or claiming an interest under such Grant. Grants under a particular Section of the Plan need not be uniform as among the Participants.

5. Shares Subject to the Plan

(a) Shares Authorized. Subject to adjustment as described in Section 5(d), the total aggregate number of shares of Company Stock that may be issued or transferred under the Plan is (i) 7,350,000 shares, minus (ii) the number of shares of Company Stock subject to grants of awards made under the Prior Plan after December 30, 2016.

(b) Source of Shares; Share Counting. Shares issued under the Plan may be authorized but unissued shares of Company Stock or reacquired shares of Company Stock, including shares purchased by the Company on the open market for purposes of the Plan. If and to the extent

-5-

Options or SARs granted under the Plan terminate, expire, or are canceled, forfeited, exchanged or surrendered without having been exercised, and if and to the extent that any Stock Awards, Stock Units, or Other Stock-Based Awards are forfeited or terminated, or otherwise are not paid in full, the shares reserved for such Grants shall again be available for purposes of the Plan. Shares of Stock surrendered in payment of the Exercise Price of an Option, and shares withheld or surrendered for payment of taxes, shall not be available for re-issuance under the Plan. If SARs are granted, the full number of shares subject to the SARs shall be considered issued under the Plan, without regard to the number of shares issued upon exercise of the SARs and without regard to any cash settlement of the SARs. To the extent that a Grant of Stock Units is designated in the Grant Agreement to be paid in cash, and not in shares of Company Stock, such Grants shall not count against the share limits in Section5(a).

(c) Individual Limits. All Grants under the Plan shall be expressed in shares of Company Stock. The maximum aggregate number of shares of Company Stock with respect to which all Grants may be made under the Plan during any calendar year to any Employee and Non-Employee Director shall be 300,000 and 150,000 shares, respectively, each subject to adjustment as described in Section 5(d). The maximum aggregate number of shares of Company Stock with respect to which all Grants described in Section 12 of the Plan may be made during any calendar year to any Participant who is a “covered employee” within the meaning of section 162(m) of the Code shall be 300,000 shares, subject to adjustment as described in Section 5(d). The individual limits of this Section 5(c) shall apply without regard to whether the Grants are to be paid in Company Stock or cash. All cash payments (other than with respect to Dividend Equivalents) shall equal the Fair Market Value of the shares of Company Stock to which the cash payments relate. A Participant may not accrue Dividend Equivalents during any calendar year in excess of $1,500,000.

(d) Adjustments. If there is any change in the number or kind of shares of Company Stock outstanding (i) by reason of a stock dividend, spinoff, recapitalization, stock split, or combination or exchange of shares, (ii) by reason of a merger, reorganization or consolidation, (iii) by reason of a reclassification or change in par value, or (iv) by reason of any other extraordinary or unusual event affecting the outstanding Company Stock as a class without the Company’s receipt of consideration, or if the value of outstanding shares of Company Stock is substantially reduced as a result of a spinoff or the Company’s payment of an extraordinary dividend or distribution, the maximum number of shares of Company Stock available for issuance under the Plan, the maximum number of shares of Company Stock for which any Employee, Non-Employee Director or “covered employee” within the meaning of section 162(m) of the Code may receive Grants in any year, the kind and number of shares covered by outstanding Grants, the kind and number of shares issued and to be issued under the Plan, and the price per share or the applicable market value of such Grants shall be equitably adjusted by the Committee, in such manner as the Committee deems appropriate, to reflect any increase or decrease in the number of, or change in the kind or value of, the issued shares of Company Stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits under the Plan and such outstanding Grants; provided, however, that any fractional shares resulting from such adjustment shall be eliminated. In addition, in the event of a Change of Control of the Company, the provisions of section 16 of the Plan shall apply. Any adjustments to outstanding Grants shall be consistent with section 409A or 422 of the Code, to the extent applicable. Any adjustments determined by the Committee shall be final, binding and conclusive.

(a) Eligible Persons. All Employees and Non-Employee Directors shall be eligible to participate in the Plan.

(b) Selection of Participants. The Committee shall select the Employees and Non-Employee Directors to receive Grants and shall determine the number of shares of Company Stock subject to each Grant.

7. Options

(a) General Requirements. The Committee may grant Options to an Employee or a Non-Employee Director upon such terms and conditions as the Committee deems appropriate under this Section 7. The Committee shall determine the number of shares of Company Stock that will be subject to each Grant of Options to Employees and Non-Employee Directors. Dividend Equivalents shall not be granted with respect to an Option.

(b) Type of Option, Price and Term.

(i) The Committee may grant Incentive Stock Options or Nonqualified Stock Options or any combination of the two, all in accordance with the terms and conditions set forth herein. Incentive Stock Options may be granted only to Employees of the Company or its parents or subsidiaries, as defined in section 424 of the Code. Nonqualified Stock Options may be granted to Employees or Non-Employee Directors.

(ii) The Exercise Price of Company Stock subject to an Option shall be determined by the Committee and shall be equal to or greater than the Fair Market Value of a share of Company Stock on the date the Option is granted. However, an Incentive Stock Option may not be granted to an Employee who, at the time of grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary, as defined in section 424 of the Code, unless the Exercise Price per share is not less than 110% of the Fair Market Value of the Company Stock on the date of grant.

(iii) The Committee shall determine the term of each Option, which shall not exceed ten years from the date of grant. However, an Incentive Stock Option that is granted to an Employee who, at the time of grant, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary, as defined in section 424 of the Code, may not have a term that exceeds five years from the date of grant.

(c) Vesting and Exercisability of Options.

(i) Options shall become vested and exercisable in accordance with such terms and conditions as may be determined by the Committee and specified in the Grant Agreement. The Committee may grant Options that are subject to achievement of performance goals or other conditions. The Committee may accelerate the vesting and exercisability of any or all outstanding Options at any time for any reason.

(ii) Options granted to persons who are non-exempt employees under the Fair Labor Standards Act of 1938, as amended, may not be exercisable for at least six months after the date of grant (except that such Options may become exercisable, as determined by the Committee, upon the Participant’s death, disability or retirement, or upon a Change of Control or other circumstances permitted by applicable regulations).

-7-

(d) Termination of Employment or Service. Except as provided in the Grant Agreement, an Option may only be exercised while the Participant is employed as an Employee or providing service as a Non-Employee Director. The Committee shall determine in the Grant Agreement under what circumstances and during what time periods a Participant may exercise an Option after termination of employment or service.

(e) Exercise of Options. A Participant may exercise an Option that has become exercisable, in whole or in part, by delivering a notice of exercise to the Company. The Participant shall pay the Exercise Price for the Option (i) in cash or by check, (ii) if permitted by the Committee, by delivering shares of Company Stock owned by the Participant and having a Fair Market Value on the date of exercise equal to the Exercise Price or by attestation to ownership of shares of Company Stock having an aggregate Fair Market Value on the date of exercise equal to the Exercise Price, (iii) by payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board, (iv)  if permitted by the Grant Agreement, by net share settlement of the Option based on the Fair Market Value on the date of exercise, (v) any combination of clauses (i), (ii), (iii) or (iv) above, or (vi) by such other method as the Committee may approve, to the extent permitted by applicable law. Shares of Company Stock delivered to exercise an Option pursuant to clause (ii) above shall have been held by the Participant for the requisite period of time to avoid adverse accounting consequences to the Company with respect to the Option. Payment for the shares pursuant to the Option, and any required withholding taxes, must be received by the time specified by the Committee depending on the type of payment being made, but in all cases prior to the issuance of the Company Stock.

(f) Limits on Incentive Stock Options. Each Incentive Stock Option shall provide that, if the aggregate Fair Market Value of the stock on the date of grant with respect to which Incentive Stock Options are exercisable for the first time by a Participant during any calendar year, under the Plan or any other stock option plan of the Company or a parent or subsidiary, as defined in section 424 of the Code, exceeds $100,000, then the Option, as to the excess, shall be treated as a Nonqualified Stock Option. An Incentive Stock Option shall not be granted to any person who is not an Employee of the Company or a parent or subsidiary, as defined in section 424 of the Code. The aggregate number of shares of Company Stock that may be issued under the Plan as Incentive Stock Options is 5,000,000 shares, subject to adjustment as described in Section 5(d), and all shares issued under the Plan as Incentive Stock Options shall count against the plan limit under Section 5(a).

8. Stock Units

(a) General Requirements. The Committee may grant Stock Units to an Employee or a Non-Employee Director, upon such terms and conditions as the Committee deems appropriate under this Section 8. Each Stock Unit shall represent the right of the Participant to receive a share of Company Stock or an amount based on the value of a share of Company Stock. All Stock Units shall be credited to bookkeeping accounts on the Company’s records for purposes of the Plan.

(b) Terms of Stock Units. The Committee may grant Stock Units that are payable on terms and conditions determined by the Committee, which may include payment based on achievement of performance goals. Stock Units may be paid at the end of a specified vesting or performance period, or payment may be deferred to a date authorized by the Committee. The Committee shall determine the number of Stock Units to be granted and the requirements applicable to such Stock Units. The Committee may accelerate the vesting of any or all outstanding Stock Units at any time for any reason.

-8-

(c) Payment With Respect to Stock Units. Payment with respect to Stock Units shall be made in cash, in Company Stock, or in a combination of the two, as determined by the Committee. The Grant Agreement shall specify the maximum number of shares that can be issued under the Stock Units.

(d) Requirement of Employment or Service. The Committee shall determine in the Grant Agreement under what circumstances a Participant may retain Stock Units after termination of the Participant’s employment or service, and the circumstances under which Stock Units may be forfeited.

(e) Dividend Equivalents. The Committee may grant Dividend Equivalents in connection with Stock Units, under such terms and conditions consistent with this Section 8(e) as the Committee deems appropriate. Dividend Equivalents may be deferred, but no Dividend Equivalent may be payable to a Participant unless, and only to the extent, a Grant of Stock Units vests, and, with respect to a Grant of Stock Units that vests based on the achievement of performance goals, the performance goals are achieved (at least at the minimum threshold for performance).  All Dividend Equivalents that are not paid currently shall be credited to bookkeeping accounts on the Company’s records for purposes of the Plan. Dividend Equivalents may be accrued as a cash obligation, or may be converted to additional Stock Units for the Participant, and deferred Dividend Equivalents may accrue interest, all as determined by the Committee. The Committee may provide that Dividend Equivalents shall be payable based on the achievement of specific performance goals. Dividend Equivalents may be payable in cash or shares of Company Stock or in a combination of the two, as determined by the Committee. Each Dividend Equivalent with respect to a Grant of Stock Units based on performance goals will be forfeited at such time as, and to the extent that, the Committee has determined that the performance goals with respect to such Grant have not been achieved or exceeded, at least at the minimum level of performance, or, if granted in connection with a Stock Unit that vests solely based on the lapse of time, on the date the Stock Unit (or portion thereof) is forfeited as provided by the Committee.

9. Stock Awards

(a) General Requirements. The Committee may issue shares of Company Stock to an Employee or a Non-Employee Director under a Stock Award, upon such terms and conditions as the Committee deems appropriate under this Section 9. Shares of Company Stock issued pursuant to Stock Awards may be issued for cash consideration or for no cash consideration, and subject to restrictions or no restrictions, as determined by the Committee. The Committee may establish conditions under which restrictions on Stock Awards shall lapse over a period of time or according to such other criteria as the Committee deems appropriate, including restrictions based upon the achievement of specific performance goals. The Committee shall determine the number of shares of Company Stock to be issued pursuant to a Stock Award. The Committee may accelerate the vesting of any or all outstanding Stock Awards at any time for any reason.

(b) Requirement of Employment or Service. The Committee shall determine in the Grant Agreement under what circumstances a Participant may retain Stock Awards after termination of the Participant’s employment or service, and the circumstances under which Stock Awards may be forfeited.

-9-

(c) Restrictions on Transfer. While Stock Awards are subject to restrictions, a Participant may not sell, assign, transfer, pledge or otherwise dispose of the shares of a Stock Award except upon death as described in Section 15(a). If certificates are issued, each certificate for a share of a Stock Award shall contain a legend giving appropriate notice of the restrictions in the Grant. The Participant shall be entitled to have the legend removed when all restrictions on such shares have lapsed. The Company may retain possession of any certificates for Stock Awards until all restrictions on such shares have lapsed.

(d) Right to Vote and to Receive Dividends. The Committee shall determine, consistent with this Section 9(d), to what extent, and under what conditions, the Participant shall have the right to vote shares of Stock Awards and to receive any dividends or other distributions paid on such shares during the restriction period. Dividends may be deferred, but dividends payable to a Participant must be withheld while a Stock Award is subject to restrictions and such dividends may be payable only upon the lapse of the restrictions on the Stock Awards. With respect to a Stock Award that vests based on the achievement of performance goals, no dividends may be payable unless, and only to the extent, the performance goals are achieved (at least at the minimum threshold for performance). Dividends that are not paid currently shall be credited to bookkeeping accounts on the Company’s records for purposes of the Plan. Accumulated dividends may accrue interest, as determined by the Committee, and shall be paid in cash, shares of Company Stock, or in such other form as dividends are paid on Company Stock, as determined by the Committee. Dividends with respect to a Grant of Stock Awards based on performance goals will be forfeited at such time as, and to the extent that, the Committee has determined that the performance goals with respect to such Grant have not been achieved or exceeded, at least at the minimum level of performance, or, if granted in connection with a Stock Award that vests solely based on the lapse of time, on the date the Stock Award (or portion thereof) is forfeited as provided by the Committee.

10. Stock Appreciation Rights

(a) General Requirements. The Committee may grant SARs to an Employee or a Non-Employee Director separately or in tandem with an Option. The Committee shall establish the number of shares, the terms and the base amount of the SAR at the time the SAR is granted. The base amount of each SAR shall be not less than the Fair Market Value of a share of Company Stock as of the date of grant of the SAR. The Committee shall determine the term of each SAR, which shall not exceed ten years from the date of grant. Dividend Equivalents shall not be granted with respect to a SAR.

(b) Tandem SARs. The Committee may grant tandem SARs at the time the Option is granted. In the case of tandem SARs, the number of SARs granted to a Participant that shall be exercisable during a specified period shall not exceed the number of shares of Company Stock that the Participant may purchase upon the exercise of the related Option during such period. Upon the exercise of an Option, the SARs relating to the Company Stock covered by such Option shall terminate. Upon the exercise of SARs, the related Option shall terminate to the extent of an equal number of shares of Company Stock.

-10-

(c) Exercisability. A SAR shall become exercisable in accordance with such terms and conditions as may be specified. The Committee may grant SARs that are subject to achievement of performance goals or other conditions. The Committee may accelerate the exercisability of any or all outstanding SARs at any time for any reason. The Committee shall determine in the Grant Agreement under what circumstances and during what periods a Participant may exercise a SAR after termination of employment or service. A tandem SAR shall be exercisable only while the Option to which it is related is exercisable.

(d) Grants to Non-Exempt Employees. SARs granted to persons who are non-exempt employees under the Fair Labor Standards Act of 1938, as amended, may not be exercisable for at least six months after the date of grant (except that such SARs may become exercisable, as determined by the Committee, upon the Participant’s death, Disability or retirement, or upon a Change of Control or other circumstances permitted by applicable regulations).

(e) Exercise of SARs. When a Participant exercises SARs, the Participant shall receive in settlement of such SARs an amount equal to the value of the stock appreciation for the number of SARs exercised. The stock appreciation for a SAR is the amount by which the Fair Market Value of the underlying Company Stock on the date of exercise of the SAR exceeds the base amount of the SAR as specified in the Grant Agreement.

(f) Form of Payment. The Committee shall determine whether the stock appreciation for a SAR shall be paid in the form of shares of Company Stock, cash or a combination of the two. For purposes of calculating the number of shares of Company Stock to be received, shares of Company Stock shall be valued at their Fair Market Value on the date of exercise of the SAR. If shares of Company Stock are to be received upon exercise of a SAR, cash shall be delivered in lieu of any fractional share.

11. Other Stock-Based Awards

The Committee may make other Grants not specified in Sections 7, 8, 9 or 10 above that are based on or measured by Company Stock to Employees and Non-Employee Directors, on such terms and conditions as the Committee deems appropriate. Other Stock-Based Awards may be granted subject to achievement of performance goals or other conditions and may be payable in Company Stock or cash, or in a combination of the two, as determined by the Committee in the Grant Agreement.

12. Qualified Performance-Based Compensation

(a) Designation as Qualified Performance-Based Compensation. The Committee may determine that Stock Units, Stock Awards, Dividend Equivalents or Other Stock-Based Awards granted to an Employee shall be considered “qualified performance-based compensation” under section 162(m) of the Code, in which case the provisions of this Section 12 shall apply.

(b) Performance Goals. When Grants are made under this Section 12, the Committee shall establish in writing (i) the objective performance goals that must be met, (ii) the period during which performance will be measured, (iii) the maximum amounts that may be paid if the performance goals are met, and (iv) any other conditions that the Committee deems appropriate and consistent with the requirements of section 162(m) of the Code for “qualified performance-based compensation.” The performance goals shall satisfy the requirements for “qualified

-11-

performance-based compensation,” including the requirement that the achievement of the goals be substantially uncertain at the time they are established and that the performance goals be established in such a way that a third party with knowledge of the relevant facts could determine whether and to what extent the performance goals have been met. The Committee shall not have discretion to increase the amount of compensation that is payable, but may reduce the amount of compensation that is payable, pursuant to Grants identified by the Committee as “qualified performance-based compensation.”

(c) Criteria Used for Objective Performance Goals. The Committee shall use objectively determinable performance goals based on one or more of the following criteria: (i) stock price; (ii) net income or earnings per share of Company Stock; (iii) price-earnings multiples; (iv) gross, operating or net earnings before or after income taxes; (v) book value of any asset or security; (vi) revenue; (vii) number of days sales outstanding of accounts receivable; (viii) productivity; (ix) gross income, profitability or gross margin; (x) EBITDA (earnings before interest, taxes, depreciation and amortization); (xi) net capital employed; (xii) return on equity, cash flow, investment or assets; (xiii) internal rate of return; (xiv) cash flow return on investment; (xv) improvements in capital structure; (xvi) stockholder return, including absolute or relative total stockholder return, expressed either on a dollar or percentage basis; (xvii) retention of customers, expressed on a dollar or percentage basis; (xviii) return on capital employed; (xix) increase in the Company’s or a subsidiary’s customer satisfaction or responsiveness ratings (based on the results of surveys conducted by an independent third party) and reputation within one or more service territories; (xx) cash flow per share; (xxi) economic value added (defined to mean net operating profit minus the cost of capital); (xxii) market value added (defined to mean the difference between the market value of debt and equity, and economic book value); (xxiii) growth in assets, unit volume, sales, cash flow or market share; (xxiv) relative performance (as measured by one or more of the performance goals set forth in this Section 12(c)) to a comparison group of companies designated by the Committee; (xxv) level of expenses, including without limitation capital expenditures or operation and maintenance expenses (expressed on a dollar or percentage basis); (xxvi) combined ratio; (xxvii) payback period on investment; (xxviii) net present value of investment; (xxix) metrics regarding execution on business or operating initiatives, such as through the development or implementation of new technologies or other customer benefits; (xxx) safety (including, for example, criteria relating to numbers or ratios of reported injuries, preventable accidents and vehicular accidents); (xxxi) compliance with environmental laws, rules and regulations; (xxxii) compliance with financial and regulatory controls; (xxxiii) bad debt collections, expenses or losses; (xxxiv) budget achievement; (xxxv) risk management; and (xxxvi) strategic business criteria consisting of one or more objectives based on meeting specified revenue goals, market penetration goals, customer growth, geographic business expansion goals, cost targets or goals relating to acquisitions or divestitures. The performance goals may be based on one or more business criteria that relate to, individually or in any combination (a) a specified goal, (b) historical performance of the Company or a product, service or business line or segment, (c) one or more business units or the performance of the Company and its subsidiaries as a whole, (d) the performance of any other corporation or entity or group of corporations or entities or a product, service or business line or segment, unit, division or subsidiary thereof, or (e) an individual or groups of individuals. Performance goals need not be uniform as among Participants.

-12-

(d) Timing of Establishment of Goals. The Committee shall establish the performance goals in writing either before the beginning of the performance period or during a period ending no later than the earlier of (i) 90 days after the beginning of the performance period or (ii) the date on which 25% of the performance period has been completed, or such other date as may be required or permitted under applicable regulations under section 162(m) of the Code.

(e) Certification of Results. The Committee shall certify the performance results for the performance period specified in the Grant Agreement after the performance period ends. The Committee shall determine the amount, if any, to be paid pursuant to each Grant based on the achievement of the performance goals and the satisfaction of all other terms of the Grant Agreement.

(f) Death, Disability or Other Circumstances. The Committee may provide in the Grant Agreement that Grants under this Section 12 shall be payable, in whole or in part, in the event of the Participant’s death or disability, a Change of Control or under other circumstances consistent with the Treasury regulations and rulings under section 162(m) of the Code.

(g) Certain Events.  To the extent permitted by section 162(m) of the Code, if applicable, in setting performance goals within the period prescribed in Section 12(d), the Committee may at such time also provide that the achievement of such performance goals will be determined without regard to the either the negative or positive effect (or both) of certain events, including for one or more of the following items:  (i) asset write-downs; (ii) litigation or claim judgments, or settlements thereof; (iii) changes in accounting principles; (iv) changes in tax law or other laws affecting reported results; (v) changes in commodity or supply prices; (vi) severance, contract termination and other costs related to exiting, modifying or reducing any business activities; (vii) costs of, and gains and losses from, the acquisition, disposition or abandonment of businesses or assets; (viii) gains and losses from the early extinguishment of debt; (ix) gains and losses in connection with the termination of or withdrawal from a pension plan; (x) stock compensation costs and other non-cash expenses; or (xi) any other specified non-operating items as determined by the Committee in setting performance goals.

13. Deferrals

The Committee may permit or require a Participant to defer receipt of the payment of cash or the delivery of shares that would otherwise be due to the Participant in connection with any Grant. The Committee shall establish rules and procedures for any such deferrals, consistent with applicable requirements of section 409A of the Code.

14. Withholding of Taxes

(a) Required Withholding. All Grants under the Plan shall be subject to applicable federal (including FICA), state and local tax withholding requirements. The Company may require that the Participant or other person receiving or exercising Grants pay to the Company the amount of any federal, state or local taxes that the Company is required to withhold with respect to such Grants, or the Company may deduct from other wages paid by the Company the amount of any withholding taxes due with respect to such Grants.

-13-

(b) Election to Withhold Shares. If the Committee so permits, shares of Company Stock may be withheld to satisfy the Company’s tax withholding obligation with respect to Grants paid in Company Stock, at the time such Grants become taxable, up to an amount that does not exceed the minimum applicable withholding tax rate for federal (including FICA), state and local tax liabilities or such greater withholding rate as may be permitted by U.S. generally accepted accounting principles as applied to the Company.

15. Transferability of Grants

(a) Restrictions on Transfer. Except as described in Section 14 or Section 15(b) or as otherwise provided by applicable law, only the Participant may exercise rights under a Grant during the Participant’s lifetime, and no benefit provided under this Plan shall be subject to alienation or assignment by a Participant (or by any Person entitled to such benefit pursuant to the terms of this Plan), nor shall it be subject to attachment or other legal process except by will or by the laws of descent and distribution. When a Participant dies, the personal representative or other person entitled to succeed to the rights of the Participant may exercise such rights. Any such successor must furnish proof satisfactory to the Company of his or her right to receive the Grant under the Participant’s will or under the applicable laws of descent and distribution.

(b) Transfer of Nonqualified Stock Options to or for Family Members. Notwithstanding the foregoing, the Committee may provide, in a Grant Agreement, that a Participant may transfer Nonqualified Stock Options to one or more immediate family members, or one or more trusts or other entities for the benefit of or owned by immediate family members, consistent with applicable securities laws, according to such terms as the Committee may determine; provided, however, that the Participant receives no consideration for the transfer of a Nonqualified Stock Option and the transferred Nonqualified Stock Option shall continue to be subject to the same terms and conditions as were applicable to the Nonqualified Stock Option immediately before the transfer.

16. Consequences of a Change of Control

(a) Assumption of Grants.  Upon a Change of Control where the Company is not the surviving corporation (or survives only as a subsidiary of another corporation or entity (the “surviving corporation”)), all outstanding Options and SARs that are not exercised shall be assumed by, or replaced with comparable options or rights by, the surviving corporation (or a parent or subsidiary of the surviving corporation), and other outstanding Grants shall be converted to similar grants of the surviving corporation (or a parent or subsidiary of the surviving corporation). Notwithstanding the immediately preceding sentence, if, in connection with such Change of Control, any outstanding Options and SARs are not assumed by, or replaced with comparable options or rights by, the surviving corporation (or a parent or subsidiary of the surviving corporation), and any other outstanding Grants are not converted to similar grants of the surviving corporation (or a parent or subsidiary of the surviving corporation), then upon such Change of Control (i) all such outstanding Options and SARs that are not assumed or replaced shall accelerate and become fully exercisable, (ii) the restrictions and conditions on all such outstanding Stock Awards that are not converted to similar grants shall fully lapse and (iii) all such outstanding Stock Units, Other Stock-Based Awards and Dividend Equivalents that are not converted to similar grants shall be fully vested.

(b) Acceleration of Exercisability/Vesting.  If a Participant’s Grant is assumed as provided in the first sentence of Section 16(a) and if, within the twelve (12) month period following the occurrence of such Change of Control, such Participant ceases to be employed by, or providing service to, the surviving corporation (or a parent or subsidiary of the surviving corporation) on account of (x) a termination of such Participant’s employment by the surviving corporation (or a parent or subsidiary of the surviving corporation) for any reason other than on account of Cause, death or Disability, or (y) a termination of employment or service by the Participant for Good Reason, then as of the date of such termination of employment or service, then (i) a Grant that is an Optionor SAR shall automatically accelerate and become fully exercisable, (ii) a Grant that is a Stock Award shall have all restrictions and conditions immediately lapse and (iii) a Grant that is a Stock Unit, Other Stock-Based Award or Dividend Equivalent shall be fully vested.

(c) Other Alternatives.  Notwithstanding the foregoing, in the event of a Change of Control, the Committee may take any of the following actions with respect to any or all outstanding Grants: the Committee may (i) determine that outstanding Options and SARs shall accelerate and become fully exercisable, in whole or part; (ii) determine that the restrictions and conditions on outstanding Stock Awards shall lapse, in whole or part; (iii) determine that outstanding Stock Units, Other Stock-Based Awards and Dividend Equivalents shall be fully vested, in whole or part; (iv) require that Participants surrender their outstanding Options and SARs in exchange for a payment by the Company, in cash or Company Stock as determined by the Committee, in an amount equal to the amount by which the then Fair Market Value of the shares of Company Stock subject to the Participant’s unexercised Options and SARs exceeds the Exercise Price of the Options or the base amount of the SARs, as applicable; (v) after giving Participants an opportunity to exercise their outstanding Options and SARs, terminate any or all unexercised Options and SARs at such time as the Committee deems appropriate; or (vi) determine that Participants shall receive a payment in settlement of outstanding Stock Awards, Stock Units, Dividend Equivalents or Other Stock-Based Awards, if permitted under section 409A of the Code.  Such surrender, termination or payment will take place as of the date of the Change of Control or such other date as the Committee may specify.  Without limiting the foregoing, if the per share Fair Market Value of the Company Stock equals or is less than the per share Exercise Price or base amount, as applicable, the Company shall not be required to make any payment to the Participant upon surrender of the Option or SAR.

17. Requirements for Issuance of Shares

The Company shall be under no obligation to register under the 1933 Act any of the shares of Company Stock issued, delivered or paid in settlement under the Plan. No Company Stock shall be issued in connection with any Grant hereunder unless and until all legal requirements applicable to the issuance of such Company Stock have been complied with to the satisfaction of the Committee. The Committee shall have the right to condition any Grant made to any Participant hereunder on such Participant’s undertaking in writing to comply with such restrictions on his or her subsequent disposition of such shares of Company Stock as the Committee shall deem necessary or advisable, and one or more legends may be placed upon such shares (whether certificated or otherwise) to reflect any such restrictions. Shares of Company Stock issued under the Plan will be subject to such stop-transfer orders and other restrictions as may be required by applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon to reflect the existence of any such orders or restrictions. No Participant shall have any right as a stockholder with respect to Company Stock covered by a Grant until shares have been issued to the Participant in accordance with all of the requirements of this Section.

-15-

18. Amendment and Termination of the Plan

(a) Amendment. The Board may amend or terminate the Plan at any time; provided, however, that the Board shall not amend the Plan without approval of the stockholders of the Company if such approval is required in order to comply with the Code or applicable laws, or to comply with applicable stock exchange requirements. No amendment or termination of this Plan shall, without the consent of the Participant, materially impair any rights or obligations under any Grant previously made to the Participant under the Plan, unless such right has been reserved in the Plan or the Grant Agreement, or except as provided in Section 19(b) below. Notwithstanding anything in the Plan to the contrary, the Board may amend the Plan in such manner as it deems appropriate in the event of a change in applicable law or regulations.

(b) No Repricing Without Stockholder Approval. Except in connection with a corporate transaction described above in Section 5(d) involving the Company, neither the Plan nor the terms of any outstanding Grant may be amended to permit, and no Grant or an amendment to any Grant Agreement may have the effect of causing, Options or SARs to be repriced, replaced or regranted through cancellation or by decreasing the Exercise Price of an outstanding Option or SAR without in each case obtaining stockholder approval. This Section 18(b) does not apply to an exercise of an Option or SAR in accordance with Section 7(e) or 10(c) and the terms thereof set forth in a Grant Agreement.

(c) Stockholder Approval for “Qualified Performance-Based Compensation.” If Grants are made under Section 12 above, the Plan must be reapproved by the Company’s stockholders no later than the first stockholders’ meeting that occurs in the fifth year following the year in which the stockholders previously approved the provisions of Section 12, if additional Grants are to be made under Section 12 and if required by section 162(m) of the Code or the regulations thereunder.

(d) Termination of Plan. The Plan shall terminate on the day immediately preceding the tenth anniversary of its Effective Date, unless the Plan is terminated earlier by the Board or an amendment to the Plan to extend such termination date is recommended and approved by the Board, and approved by the stockholders. The termination of the Plan shall not impair the power and authority of the Committee with respect to an outstanding Grant.

19. Miscellaneous

(a) Effective Date. The Plan shall be effective as of the Effective Date.

(b) Grants in Connection with Corporate Transactions and Otherwise. Nothing contained in this Plan shall be construed to (i) limit the right of the Committee to make Grants under this Plan in connection with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business or assets of any corporation, firm or association, including Grants to employees thereof who become Employees, or for other proper corporate purposes, or (ii) subject to applicable law, rules and regulations, limit the right of the Company to grant stock options or make other stock-based awards outside of this Plan. Without limiting the foregoing, the Committee may make a Grant to an employee of another corporation who becomes an Employee by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation involving the Company in substitution for a grant made by such corporation. The terms and conditions of the Grants may vary from the terms and conditions required by the Plan and from those of the substituted stock incentives, as determined by the Committee.

-16-

(c) Compliance with Laws. The Plan, the exercise of Options and the obligations of the Company to issue or transfer shares of Company Stock under Grants shall be subject to all applicable laws and to approvals by any governmental or regulatory agency as may be required. With respect to persons who are officers or Employees subject to section 16 of the Exchange Act, it is the intent of the Company that the Plan and all transactions under the Plan comply with all applicable provisions of Rule 16b-3 or its successors under the Exchange Act. In addition, it is the intent of the Company that Incentive Stock Options comply with the applicable provisions of section 422 of the Code, that Grants of “qualified performance-based compensation” comply with the applicable provisions of section 162(m) of the Code and that, to the extent applicable, Grants comply with the requirements of section 409A of the Code or an exception from such requirements. To the extent that any legal requirement of section 16 of the Exchange Act or section 422, 162(m) or 409A of the Code as set forth in the Plan ceases to be required under section 16 of the Exchange Act or section 422, 162(m) or 409A of the Code, that Plan provision shall cease to apply. The Committee may revoke any Grant if it is contrary to law or modify a Grant to bring it into compliance with any valid and mandatory government regulation. The Committee may also adopt rules regarding the withholding of taxes on payments to Participants. The Committee may, in its sole discretion, agree to limit its authority under this Section.

(d) Section 409A.  The Plan is intended to comply with the requirements of section 409A of the Code, to the extent applicable. All Grants shall be construed and administered such that the Grant either (i) qualifies for an exemption from the requirements of section 409A of the Code or (ii) satisfies the requirements of section 409A of the Code. If a Grant is subject to section 409A of the Code, (i) distributions shall only be made in a manner and upon an event permitted under section 409A of the Code, (ii) payments to be made upon a termination of employment shall only be made upon a “separation from service” under section 409A of the Code, (iii) payments to be made upon a Change of Control shall only be made upon a “change of control event” under section 409A of the Code, (iv) unless the Grant specifies otherwise, each payment shall be treated as a separate payment for purposes of section 409A of the Code and all installment payments shall be treated as a separate payment, and (v) in no event shall a Participant, directly or indirectly, designate the calendar year in which a distribution is made except in accordance with section 409A of the Code. Any Grant granted under the Plan that is subject to section 409A of the Code and that is to be distributed to a key employee (as defined below) upon separation from service shall be administered so that any distribution with respect to such Grant shall be postponed for six months following the date of the Participant’s separation from service, if required by section 409A of the Code. If a distribution is delayed pursuant to section 409A of the Code, the distribution shall be paid within 30 days after the end of the six-month period. If the Participant dies during such six-month period, any postponed amounts shall be paid within 60 days of the Participant’s death. The determination of key employees, including the number and identity of persons considered key employees and the identification date, shall be made by the Committee or its delegate each year in accordance with section 416(i) of the Code and the “specified employee” requirements of section 409A of the Code.  Notwithstanding the foregoing, although Grants are intended to be exempt from, or comply with, the requirements of section 409A of the Code, and the Plan shall be interpreted accordingly, the Company does not warrant that any Grant will qualify for favorable tax treatment under section 409A of the Code or any other provision of federal, state, local or foreign law. The Company shall not be liable to any Participant for any tax the Participant might owe as a result of the grant, holding, vesting, exercise, or payment of any Grant under the Plan.

-17-

(d) Enforceability; Company Successors. The Plan shall be binding upon and enforceable against the Company and its successors and assigns. In the event the Company becomes a party to a merger, consolidation, sale of substantially all of its assets or any other corporate reorganization in which the Company will not be the surviving corporation or in which the holders of the Company Stock will receive securities of another corporation, then such other corporation shall be assigned the rights and assume the obligations of the Company under this Plan.

(e) Funding of the Plan; Limitation on Rights. This Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Grants under this Plan. Nothing contained in the Plan and no action taken pursuant hereto shall create or be construed to create a fiduciary relationship between the Company and any Participant or any other person. No Participant or any other person shall under any circumstances acquire any property interest in any specific assets of the Company. To the extent that any person acquires a right to receive payment from the Company hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company.

(f) Rights of Participants. Nothing in this Plan shall entitle any Employee, Non-Employee Director or other person to any claim or right to receive a Grant under this Plan. Neither this Plan nor any action taken hereunder shall be construed as giving any individual any rights to be retained by or in the employment or service of the Company or any other Employer. Participation in this Plan shall not constitute a contract of employment between the Company or any Employer and any Participant and shall not be deemed to be consideration for, or a condition of, continued employment or service of any Participant. A Participant’s right, if any, to serve the Employer as an Employee or Non-Employee Director or otherwise shall not be enlarged or otherwise affected by his or her designation as a Participant under the Plan.

(g) No Fractional Shares. No fractional shares of Company Stock shall be issued or delivered pursuant to the Plan or any Grant. The Committee shall determine whether cash, other awards or other property shall be issued or paid in lieu of such fractional shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated.

(h) Employees Subject to Taxation Outside the United States. With respect to Participants who are subject to taxation in countries other than the United States, the Committee may make Grants on such terms and conditions as the Committee deems appropriate to comply with the laws of the applicable countries, and the Committee may create such procedures, addenda and subplans and make such modifications as may be necessary or advisable to comply with such laws.

(i) Clawback Provisions.  If a Participant is subject to the provisions of (i) section 304 of the Sarbanes-Oxley Act of 2002 and/or (ii) any policies adopted by the Company in accordance with rules that may be promulgated by the Securities and Exchange Commission pursuant to section 10D of the Exchange Act (individually or collectively, the “Clawback Rules”), all Grants under the Plan to such Participant shall be subject to all applicable clawback or recoupment policies or practices of the Company.  In addition, all Grants under the Plan shall be subject to  (a) the Company’s insider and share trading, and stock ownership and retention requirements, policies and guidelines, and (b) other requirements, policies, practices or guidelines implemented by the Board or the Committee, as may be in effect from time to time.

-18-

(j) Relationship to Other Benefits. Any Grants under this Plan are not considered compensation for purposes of determining benefits under any pension, profit sharing, or other retirement or welfare plan, or for any other general employee benefit program.

(k) Expenses. The expenses of administering the Plan shall be borne by the Company and its subsidiaries.

(l) Titles and Headings. The titles and headings of the sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

(m) Indemnification. Each person who is or at any time serves as a member of the Board or the Committee (and each person to whom the Board or the Committee has delegated any of its authority or power under this Plan) shall be indemnified and held harmless by the Company against and from (i) any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such person in connection with or resulting from any claim, action, suit, or proceeding to which such person may be a party or in which such person may be involved by reason of any action or failure to act under the Plan; and (ii) any and all amounts paid by such person in satisfaction of judgment in any such action, suit, or proceeding relating to the Plan. Each person covered by this indemnification shall give the Company an opportunity, at its own expense, to handle and defend the same before such person undertakes to handle and defend it on such person’s own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Restated Certificate of Incorporation or Amended and Restated Bylaws of the Company or any of its subsidiaries, as a matter of law, or otherwise, or any power that the Company may have to indemnify such person or hold such person harmless.

(n) Reliance on Reports. Each member of the Board or the Committee (and each person to whom the Board or the Committee has delegated any of its authority or power under this Plan) shall be fully justified in relying or acting in good faith upon any report made by the independent public accountants of the Company and its subsidiaries and upon any other information furnished in connection with the Plan. In no event shall any person who is or shall have been a member of the Board or the Committee (or their delegates) be liable for any determination made or other action taken or any omission to act in reliance upon any such report or information or for any action taken, including the furnishing of information, or failure to act, if in good faith.

(o) Governing Law. The validity, construction, interpretation and effect of the Plan and Grant Agreements issued under the Plan shall be governed and construed by and determined in accordance with the laws of the State of Delaware, without giving effect to the conflict of laws provisions thereof.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Basis of Presentation

Note 1: Basis of Presentation

The unaudited consolidated financial statements provided in this report include the accounts of American Water Works Company, Inc. and all of its subsidiaries (collectively, “American Water” or the “Company”) in which a controlling interest is maintained after the elimination of intercompany accounts and transactions. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting and with the rules and regulations for reporting on 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 June 30, 2017 and 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 Consolidated Balance Sheet as of December 31, 2016 is derived from the Company's audited consolidated financial statements as of December 31, 2016. 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, 2016 (“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, due primarily to the seasonality of the Company’s operations.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]

New Accounting Standards

Note 2: New Accounting Standards

The Company adopted the following accounting standard on January 1, 2017:

Standard	Description	Date of Adoption	Application	Estimated Effect on the Consolidated Financial Statements (or Other Significant Matters)
Simplification of Employee Share-Based Payment Accounting	Simplified accounting and disclosure requirements for share-based payment awards. The updated guidance addresses simplification in areas such as: (i) the recognition of excess tax benefits and deficiencies; (ii) the classification of excess tax benefits and taxes paid on the Consolidated Statements of Cash Flows; (iii) election of an accounting policy for forfeitures; and (iv) the amount an employer can withhold to cover income taxes and still qualify for equity classification.	January 1, 2017	Modified retrospective for the recognition of excess tax benefits and deficiencies; full retrospective for the classification of excess tax benefits and taxes paid on the Consolidated Statements of Cash Flows	The adoption of this standard resulted in a cumulative effect to increase retained earnings by $21, with an offsetting decrease to deferred income taxes, net. Also, the adoption resulted in a net increase in cash flows from operating activities and a net decrease in cash flows from financing activities of $14 and $18 for the six months ended June 30, 2017 and 2016, respectively, on the Consolidated Statements of Cash Flows.

The following recently issued accounting standards are not yet required to be adopted by the Company as of June 30, 2017:

Standard	Description	Date of Adoption	Permitted Application	Estimated Effect on the Consolidated Financial Statements (or Other Significant Matters)
Revenue from Contracts with Customers	Changes the criteria for recognizing revenue from a contract with a customer. Replaces existing guidance on revenue recognition, including most industry specific guidance. The objective is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets.  The underlying principle is that an entity will recognize revenue to depict the transfer of goods and services to customers at an amount the entity expects to be entitled to in exchange for those goods or services.  The guidance also requires a number of disclosures regarding the nature, amount, timing and uncertainty of revenue and the related cash flows.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company substantially completed its evaluation of the requirements of the new standard based on current interpretations and does not expect there to be a change in the measurement or timing of revenue recognized. The Company continues to monitor for new authoritative and interpretative guidance, which upon release could impact the Company’s current evaluation. The Company plans to adopt the new standard on January 1, 2018 using the modified retrospective method.
Classification of Certain Cash Receipts and Cash Payments on the Statement of Cash Flows	Provides guidance on the presentation and classification in the statement of cash flows for the following cash receipts and payments: (i) debt prepayment or debt extinguishment costs; (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (iii) contingent consideration payments made after a business combination; (iv) proceeds from the settlement of insurance claims; (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (vi) distributions received from equity method investees; (vii) beneficial interests in securitization transactions and (viii) separately identifiable cash flows and application of the predominance principle.	January 1, 2018; early adoption permitted	Retrospective	The Company does not anticipate significant impacts on its consolidated statements of cash flows.
Presentation of Changes in Restricted Cash on the Statement of Cash Flows	Updates the accounting and disclosure guidance for the classification and presentation of changes in restricted cash on the statements of cash flows. The amended guidance requires that the statements of cash flows explain the change during the period in the total of cash, cash equivalents and amounts described as restricted cash or restricted cash equivalents. Restricted cash and restricted cash equivalents will now be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows.	January 1, 2018; early adoption permitted	Retrospective	The Company does not anticipate significant impacts on its consolidated statements of cash flows.
Clarifying the Definition of a Business	Updates the accounting guidance to clarify the definition of a business with the objective of assisting entities with evaluating whether transactions should be accounted for as acquisitions, or disposals, of assets or businesses.	January 1, 2018; early adoption permitted	Prospective	The update could result in more acquisitions being accounted for as asset acquisitions. The effect on the Company's consolidated financial statements will be dependent on the transactions executed by the Company subsequent to adoption.
Gains and Losses from the Derecognition of Nonfinancial Assets	Updated the guidance to clarify the accounting for gains and losses resulting from the derecognition of nonfinancial assets and partial sale of nonfinancial assets. The guidance also clarifies the definition of an in-substance nonfinancial asset.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company is evaluating the impact on its consolidated financial statements and related disclosures.
Presentation of Net Periodic Pension Cost and Net Periodic  Postretirement Benefit Cost	Updated authoritative guidance requires the service cost component of net periodic benefit cost to be presented in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. The remaining components of net periodic benefit cost are required to be presented separately from the service cost component in an income statement line item outside of operating income. Also, the guidance allows for only the service cost component to be eligible for capitalization. The updated guidance does not impact the accounting for net periodic benefit costs as regulatory assets or liabilities.	January 1, 2018; early adoption permitted	Retrospective for the presentation of service cost component; prospective for the capitalization of service cost component	The Company is evaluating the impact on its consolidated financial statements and related disclosures.
Accounting for Leases	Updated the accounting and disclosure guidance for leasing arrangements. Under this guidance, a lessee will be required to recognize the following for all leases, excluding short-term leases, at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the guidance, lessor accounting is largely unchanged.	January 1, 2019; early adoption permitted	Modified retrospective	The Company is evaluating the effect on its consolidated financial statements and related disclosures.
Simplification of Goodwill Impairment Testing	Updated authoritative guidance which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amendments in the update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying value exceeds the reporting unit's fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.	January 1, 2020; early adoption permitted	Prospective	The Company is considering early adopting this guidance for its next annual goodwill impairment test, which will occur during the fourth quarter of 2017. The Company does not expect the adoption to have a material impact on its consolidated financial statements or related disclosures.
Measurement of Credit Losses	Updated the accounting guidance on reporting credit losses for financial assets held at amortized cost basis and available-for-sale debt securities. Under this guidance, expected credit losses are required to be measured based on historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount of financial assets. Also, this guidance requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a direct write-down.	January 1, 2020; early adoption permitted	Modified retrospective	The Company is evaluating the impact on its consolidated financial statements and related disclosures, as well as the timing of adoption.

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 capitalized as a regulatory asset. These accumulated other comprehensive income loss components are included in the computation of net periodic pension cost. See Note 8— Pension and Other Postretirement Benefits.

The amortization of the 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.

Anti-dilutive Stock Repurchase Program

During the six months ended June 30, 2017, the Company repurchased 0.7 shares of common stock in the open market at an aggregate cost of $54 under the anti-dilutive stock repurchase program authorized by the Company’s Board of Directors in 2015.

(a) American Water Capital Corp., which is a wholly owned subsidiary of the Company, has a support agreement with the Company that, under certain circumstances, is the functional equivalent of a parent company guarantee. This indebtedness is considered “debt” for purposes of this support agreement.

The Company has four forward starting swap agreements with an aggregate notional amount of $300 to reduce interest rate exposure on debt expected to be issued in 2017. These forward starting swap agreements terminate in December 2017 and have an average fixed rate of 2.20%. On February 8, 2017, the Company entered into an additional forward starting swap agreement with a notional amount of $100 to reduce interest rate exposure for a portion of the expected refinancing of the Company’s 5.62% fixed-rate long-term debt maturing in December 2018. This forward starting swap agreement terminates in November 2018 and has an average fixed rate of 2.67%. The Company has designated theseforward starting swap agreements as cash flow hedges and the initial fair value, in addition to any subsequent changes in fair value, are recognized in accumulated other comprehensive gain or loss. Upon termination, the cumulative gain or loss recorded in accumulated other comprehensive gain or loss will be amortized through interest, net over the term of the issued debt.

The Company has an interest rate swap to hedge $100 of its 6.085% fixed-rate debt maturing in 2017. The Company pays variable interest of six-month LIBOR plus 3.422% and the interest rate swap matures with the fixed-rate debt in 2017. The Company has designated this interest rate swap as a fair value hedge accounted for at fair value with gains or losses, as well as the offsetting gains or losses on the hedged item, recognized in interest, net. The net gain and loss recognized by the Company for the three and six months ended June 30, 2017 and 2016 was de minimis.

The Company has employed interest rate swaps to fix the interest cost on a portion of its variable-rate debt with an aggregate notional amount of $6. The Company has designated these interest rate swaps as economic hedges accounted for at fair value with gains or losses deferred as a regulatory asset or regulatory liability. The net gain recognized by the Company for the three and six months ended June 30, 2017 and 2016 was de minimis.

No ineffectiveness was recognized for the three and six months ended June 30, 2017 and 2016, related to hedging instruments.

The following table provides a summary of the gross fair value for the Company’s derivative asset and liabilities, as well as the location of the asset and liability balances in the Consolidated Balance Sheets:

Income Taxes

Note 7: Income Taxes

The Company’s effective income tax rate was41.8%and39.1%for the three months ended June 30, 2017 and 2016, respectively, and 39.5% and 39.4% for thesix months ended June 30, 2017 and 2016, respectively. The effective income tax rate for the three months ended June 30, 2017 increased when compared to the same period in 2016 due to aone-time, non-cash cumulative charge to the provision for income taxes of $4, primarily the result of legislation enacted in the State of New York during the second quarter of 2017, and a tax benefit of $3 that was recorded during the second quarter of 2016.This increase in the effective income tax rate was partially offset for the six months ended June 30, 2017, by a $5 tax benefit from the new accounting standard for employee share-based payment awards which was adopted in the first quarter of 2017. Under this updated guidance, tax benefits or shortfalls related to employee share-based payments awards are recognized in the provision for income taxes, whereas they previously were recorded as additional paid-in capital on the Consolidated Balance Sheet. See Note 2 – New Accounting Standards in the Notes to Consolidated Financial Statements for further discussion on the impacts of the updated guidance.

On April 11, 2017, the State of New York enacted legislation that increased the state income tax rate on the Company’s taxable income attributable to New York. This legislation eliminated the production of water as a qualified manufacturing activity in New York, which effectively increased the state income tax rate in New York. As a result of the legislative change, the Company was required to re-measure its cumulative deferred tax balances using the higher state income tax rate in the second quarter of 2017. This change in legislation was the primary cause of an increase to the Company’s unitary deferred tax liability of $11. The portion of this increase related to the Company’s New York subsidiary calculated on a stand-alone basis was $7, and was offset by a regulatory asset, as the Company believes it is probable of recovery in future rates. The remaining increase in the deferred tax liability was calculated through state tax apportionment rates and recorded at the consolidated level, resulting in a non-cash, cumulative charge to earnings of $4during the second quarter of 2017.

On July 7, 2017, the State of Illinois enacted legislation that would increase the state income tax rate on the Company’s taxable income attributable to Illinois from 7.75% to 9.5%. The effective date of the increase in the state tax rate is July 1, 2017. As a result of the legislative change, the Company will be required to re-measure its cumulative deferred tax balances using the higher state income tax rate in the third quarter of 2017. The portion of this increase related to the Company’s Illinois subsidiary calculated on a stand-alone basis is expected to be offset by a regulatory asset, as the Company believes it is probable of recovery in future rates. The remaining increase in the deferred tax liability will be calculated through state tax apportionment rates and recorded at the consolidated level, as a non-cash, cumulative charge to earnings during the third quarter of 2017.

Note 9: Commitments and Contingencies

Contingencies

The Company is routinely involved in legal actions incident to the normal conduct of its business. As of June 30, 2017, the Company has accrued approximately $139 of probable loss contingencies and has estimated that the maximum amount of losses associated with reasonably possible loss contingencies that can be reasonably estimated is $28. For certain matters, claims and actions, the Company is unable to estimate possible losses. The Company believes that damages or settlements, if any, recovered by plaintiffs in such matters, claims or actions, other than as described in this Note 9, will not have a material adverse effect on the Company.

West Virginia Elk River Freedom Industries Chemical Spill

Background

On January 9, 2014, a chemical storage tank owned by Freedom Industries, Inc. leaked two substances, 4-methylcyclohexane methanol, or MCHM, and PPH/DiPPH, a mix of polyglycol ethers, into the Elk River near the West Virginia-American Water Company (“WVAWC”) treatment plant intake in Charleston, West Virginia. After having been alerted to the leak of MCHM by the West Virginia Department of Environmental Protection (“DEP”), WVAWC took immediate steps to gather more information about MCHM, augment its treatment process as a precaution, and begin consultations with federal, state and local public health officials. As soon as possible after it was determined that the augmented treatment process would not fully remove the MCHM, a joint decision was reached in consultation with the West Virginia Bureau for Public Health to issue a “Do Not Use” order for all of its approximately 93,000 customer accounts in parts of nine West Virginia counties served by the Charleston treatment plant. By January 18, 2014, none of WVAWC’s customers were subject to the Do Not Use order.

Following the Freedom Industries chemical spill, numerous lawsuits were filed against WVAWC and certain other Company affiliated entities (collectively, the “American Water Defendants”) with respect to this matter in the U.S. District Court for the Southern District of West Virginia or West Virginia Circuit Courts in Kanawha, Boone and Putnam counties, and to date, 74 cases remain pending. Four of the cases pending before the U.S. district court were consolidated for purposes of discovery, and an amended consolidated class action complaint for those cases (the “Federal action”) was filed in December 2014 by several plaintiffs. On January 28, 2016, all of the then-filed state court cases were referred to West Virginia’s Mass Litigation Panel for further proceedings, which have been stayed pending the negotiation by the parties and approval by the court in the Federal action of a global agreement to settle all of such cases, as described below. On July 7, 2016, the court in the Federal action scheduled trial to begin on October 25, 2016, but the court has granted several continuances of the trial, which is currently postponed indefinitely in light of the binding global agreement in principle described below. The Mass Litigation Panel has also stayed its proceedings until October 23, 2017.

WVAWC Binding Global Agreement in Principle to Settle Claims

On October 31, 2016, the court in the Federal action approved the preliminary principles, terms and conditions of a binding global agreement in principle to settle claims (the “Settlement”) among the American Water Defendants, and all class members, putative class members, claimants and potential claimants (collectively, the “Plaintiffs”), arising out of the Freedom Industries chemical spill. The terms of the Settlement propose a global federal and state resolution of all litigation and potential claims against the American Water Defendants and their insurers. A claimant may elect to opt out of any final settlement agreement, in which case such claimant will not receive any benefit from or be bound by the terms of the Settlement. Under the terms and conditions of the Settlement and any subsequent final settlement agreement, the American Water Defendants have not admitted, and will not admit, any fault or liability for any of the allegations made by the Plaintiffs in any of the actions to be resolved.

The proposed aggregate pre-tax amount of the Settlement is $126, of which $65 would be contributed by WVAWC, and the remainder would be contributed by certain of the Company’s general liability insurance carriers. The Company has general liability insurance under a series of policies underwritten by a number of individual carriers. Two of these insurance carriers, which provide an aggregate of $50 in insurance coverage to the Company under these policies, were requested, but presently have not agreed, to participate in the Settlement. The Company and WVAWC are vigorously pursuing their rights to insurance coverage from these non-participating carriers for any contributions by WVAWC to the Settlement. In this regard, WVAWC filed a lawsuit against one of these carriers alleging that the carrier’s failure to agree to participate in the Settlement constitutes a breach of contract, and the Company is pursuing mandatory arbitration against the other non-participating carrier.

The preliminary terms of the Settlement intend to establish a two-tier settlement fund for the payment of claims, comprised of (i) a simple claim fund, which is also referred to as the “guaranteed fund,” of $76, of which $51 will be contributed by WVAWC, including insurance deductibles, and $25 would be contributed by one of the Company’s general liability insurance carriers, and (ii) an individual review claim fund of up to $50, of which up to $14 would be contributed by WVAWC and $36 would be contributed by a number of the Company’s general liability insurance carriers. Separately, up to $25 would be contributed to the guaranteed fund by another defendant to the Settlement.

As a result of these events, the Company recorded a charge to earnings, net of insurance receivables, of $65 ($39 after-tax) in the third quarter of 2016. The settlement amount of $126 is reflected in Accrued Liabilities and the offsetting insurance receivable is reflected in Other Current Assets in the Consolidated Balance Sheet as of June 30, 2017. The Company intends to fund WVAWC’s contributions to the Settlement through existing sources of liquidity, although no contribution by WVAWC will be required unless and until the terms of the Settlement are finally approved by the court in the Federal action. Furthermore, under the terms of the Settlement, WVAWC has agreed that it will not seek rate recovery from the Public Service Commission of West Virginia for approximately $4 in direct response costs expensed in 2014 by WVAWC relating to the Freedom Industries chemical spill as well as for amounts paid by WVAWC under the Settlement.

The Company’s insurance policies operate under a layered structure where coverage is generally provided in the upper layers after claims have exhausted lower layers of coverage. The $36 to be contributed by a number of the Company’s general liability insurance carriers to the individual review claim fund, as noted above, is from higher layers of the insurance structure than the two insurance carriers that were requested, but presently have not agreed, to participate in the Settlement. Any recovery by WVAWC or the Company from the non-participating carriers would reimburse WVAWC for its contributions to the guaranteed fund.

On April 27, 2017, the parties filed with the court in the Federal action a proposed settlement agreement providing details of the terms of the Settlement consistent with those described above. The parties also requested that the court in the Federal action grant preliminary approval of the Settlement.

On July 6, 2017, the court in the Federal action issued an opinion denying without prejudice the joint motion for preliminary approval of the Settlement. The court in the Federal action found the overall amount and structure of the Settlement to be fair, adequate and reasonable, but it declined to preliminarily approve the Settlement on several grounds, including the fairness of the methodology for allocating payments among members of the business class, the nature of the claims appeal process and the timing of the payment of claims that are subject to appeal, and the fairness of setting of fixed payments for the medical claims class. The American Water Defendants intend to work with the Plaintiffs to propose acceptable alternative provisions to the Settlement Agreement to satisfy the concerns of the court in the Federal action. If and when preliminary approval of the Settlement is obtained, notice of the terms of the Settlement would then be provided to members of the settlement class. Following the notice period, the court in the Federal action would hold a fairness hearing to consider final approval of the Settlement.

Other Related Proceedings

Additionally, investigations with respect to the matter have been initiated by the U.S. Chemical Safety and Hazard Investigation Board (the “CSB”), the U.S. Attorney’s Office for the Southern District of West Virginia, the West Virginia Attorney General, and the Public Service Commission of West Virginia (the “PSC”). As a result of the U.S. Attorney’s Office investigation, Freedom Industries and six former Freedom Industries employees (three of whom also were former owners of Freedom Industries), pled guilty to violations of the federal Clean Water Act.

In May 2014, the PSC issued an Order initiating a General Investigation into certain matters relating to WVAWC’s response to the Freedom Industries chemical spill. Three parties intervened in the proceeding, including the Consumer Advocate Division of the PSC and two attorney-sponsored groups, including one sponsored by some of the plaintiffs’ counsel involved in the civil litigation described above. On January 26, 2017, WVAWC and the other parties agreed to resolve the General Investigation and filed a joint stipulation with the PSC containing the terms of the settlement. The parties to the joint stipulation filed a proposed order with the PSC on February 8, 2017. On June 15, 2017, the PSC entered an order accepting the joint stipulation that had been filed by the parties in January 2017 as a reasonable basis for resolving the General Investigation and removing the proceeding from the docket. The PSC’s order did not require WVAWC to take any further action with respect to the matters covered by the General Investigation. The PSC order concludes the General Investigation.

The CSB is an independent investigatory agency with no regulatory mandate or ability to issue fines or citations; rather, the CSB can only issue recommendations for further action. In response to the Freedom Industries chemical spill, the CSB commenced an investigation shortly thereafter. On September 28, 2016, the CSB issued and adopted its investigation report in which it recommended that the Company conduct additional source water protection activities. The Company provided written comments to the CSB’s report suggesting that the recommendation made to the Company would be better directed to the U.S. Environmental Protection Agency in order to promote industry-wide implementation of the CSB’s recommendation. On February 15, 2017, the Company filed a response to the CSB’s recommendation. On April 4, 2017, the CSB indicated that the implementation by the Company of source water protection activities resolved the first two parts of the CSB’s recommendation. The CSB also noted that compliance by the Company with the third part of its recommendation is ongoing and that closure of this part is contingent upon completion of updated contingency planning for the Company’s water utilities outside of West Virginia. In light of public response to its original September 2016 investigation report, on May 11, 2017, the CSB issued a new version of this report. The primary substantive change addressed CSB’s factual evaluation of the duration and volume of contamination from the leaking tank, decreasing its estimate of the leak time but increasing the volume estimate by 10%. No substantive changes were made to the conclusions and recommendations in the original report.

On March 16, 2017, the Lincoln County (West Virginia) Commission (the “LCC”) passed a county ordinance entitled the “Lincoln County, WV Comprehensive Public Nuisance Investigation and Abatement Ordinance.” The ordinance establishes a mechanism that Lincoln County believes will allow it to pursue criminal or civil proceedings for the “public nuisance” it alleges was caused by the Freedom Industries chemical spill. On April 20, 2017, the LCC filed a complaint in Lincoln County state court against WVAWC and certain other defendants not affiliated with the Company, alleging that the Freedom Industries chemical spill caused a public nuisance in Lincoln County. On June 12, 2017, the Mass Litigation Panel entered an order granting a motion to transfer this case to its jurisdiction and stayed the case consistent with the existing stay order. The complaint seeks an injunction against WVAWC that would require the creation of various databases and public repositories of documents related to this chemical spill, as well as further study and risk assessments regarding the alleged exposure by Lincoln County residents to the released chemicals. WVAWC believes that the lawsuit is without merit and intends to vigorously contest the claims and allegations raised in the complaint.

California Public Utilities Commission Residential Rate Design Proceeding

In December 2016, the California Public Utilities Commission (the “CPUC”) issued a final decision in a proceeding involving California-American Water Company, the Company’s wholly owned subsidiary (“Cal Am”), adopting a new residential rate design for Cal Am’s Monterey District. The decision allowed for recovery by Cal Am of $32 in under-collections in the water revenue adjustment mechanism/modified cost balancing account (“WRAM/MCBA”) over a five-year period, plus interest, and modified existing conservation and rationing plans. In its decision, the CPUC noted concern regarding Cal Am’s residential tariff administration, specifically regarding the lack of verification of customer-provided information about the number of residents per household. This information was used for generating billing determinants under the tiered rate system. As a result, the CPUC kept this proceeding open to address several issues, including whether Cal Am’s residential tariff administration violated a statute, rule or CPUC decision, and if so, whether a penalty should be imposed.

On February 24, 2017, Cal Am, the Monterey Peninsula Water Management District, the CPUC’s Office of Ratepayer Advocates, and the Coalition of Peninsula Businesses filed for CPUC approval of a joint settlement agreement (the “Joint Settlement Agreement”), which among other things, proposed to resolve the CPUC’s residential tariff administration concerns by providing for a waiver by Cal Am of $0.5 of cost recovery for residential customers through the WRAM/MCBA in lieu of a penalty. Approval of the Joint Settlement Agreement, which is required for it to take effect, remains pending before the CPUC.

On March 28, 2017, the administrative law judge assigned to the proceeding issued a ruling stating there was sufficient evidence to conclude, on a preliminary basis, that Cal Am’s administration of the residential tariff violated certain provisions of the California Public Utilities Code and a CPUC decision. The ruling ordered Cal Am to show cause why it should not be penalized for these administrative violations and directed the settling parties to address whether the cost recovery waiver in the Joint Settlement Agreement was reasonable compared to a potential penalty range described by the administrative law judge. During hearings held on April 13-14, 2017, the administrative law judge clarified that this potential penalty range is $3 to $179 (calculated as a continuing violation dating back to 2000 and applying penalties of up to $20 thousand per day until January 1, 2012 and penalties of up to $50 thousand per day thereafter, reflecting a 2012 change to the relevant statute). The administrative law judge also noted that a per diem penalty may not be appropriate, as Cal Am’s monthly billing practices did not allow Cal Am to update customer-provided information for billing purposes on a daily basis. The administrative law judge has set further hearings in this proceeding for August 17, 2017, and has permitted certain of the parties, including Cal Am, to submit additional written testimony on the issue of whether Cal Am should be penalized, and if so, the reasonable amount of any such penalty.

As of June 30, 2017, the portions of this loss contingency that are probable and/or reasonable possible have been determined to be immaterial to the Company and have been included in the aggregate maximum amounts described above in the first paragraph of “Contingencies” in this Note 9.

Missouri Infrastructure System Replacement Surcharge Litigation

In March 2016, the Western District of the Missouri Court of Appeals ruled that the Missouri Public Service Commission (“MoPSC”) did not have statutory authority to issue an order in June 2015 approving an infrastructure system replacement surcharge (“ISRS”) for Missouri-American Water Company (“MAWC”), a wholly owned subsidiary of the Company. The court held that the MoPSC’s June 2015 order authorizing the ISRS increase was invalid because St. Louis County did not have a population of at least one million residents, asrequired by the statute. MAWC believes that the MoPSC’s June 2015 order authorizing the collection of ISRS revenues is lawful. In June 2016, the Missouri Supreme Court granted MAWC’s application to transfer the case from the Court of Appeals to the Missouri Supreme Court, and as a result of that order, the March 2016 ruling of the Court of Appeals was vacated.

On March 14, 2017, in a unanimous decision, the Missouri Supreme Court dismissed the case as moot, finding that there were no longer any ISRS funds in dispute because MAWC had completed a rate case during the appellate process and the disputed charges were now incorporated in base rates. On May 30, 2017, the Missouri Supreme Court denied a Motion for Rehearing filed by the Missouri Office of Public Counsel, which action concluded the litigation in this matter.

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 WVAWC’s West Relay pumping station located in the City of Dunbar. The failure of the main caused water outages and low pressure to 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 completed safely on June 30, 2015. Water service was fully restored on July 1, 2015 to all customers affected by this event.

On June 2, 2017, a class action complaint was filed in West Virginia Circuit Court in Kanawha County against WVAWC on behalf of a purported 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 plaintiff seeks 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.

The Company and WVAWC believe that WVAWC has valid, meritorious defenses to the claims raised in this class action complaint. WVAWC intends to vigorously defend itself against these allegations. Given the current stage of this proceeding, the Company cannot reasonably estimate the amount of any reasonably possible losses or a range of such losses related to this proceeding.

Fair Value of Financial Assets and Liabilities

Fair Value Disclosures [Abstract]

Fair Value of Financial Assets and Liabilities

Note 11: Fair Value of Financial Assets and Liabilities

Fair Value of Financial Instruments

The Company used the following methods and assumptions to estimate its fair value disclosures for financial instruments:

Current assets and current liabilities—The carrying amounts reported in the accompanying 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.

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. The fair values of instruments classified as Level 2 and Level 3 are determined by a valuation model that is based on a conventional discounted cash flow methodology and utilizes assumptions of current market rates. As a portion of the Company’s debts do not trade in active markets, the Company calculated a base yield curve using a risk-free rate (a U.S. Treasury securities yield curve) plus a credit spread that is based on the following two factors: (i) an average of the Company’s own publicly-traded debt securities and (ii) the current market rates for U.S. Utility A debt securities. The Company used these yield curve assumptions to derive a base yield for the Level 2 and Level 3 securities. Additionally, the Company adjusted the base yield for specific features of the debt securities including call features, coupon tax treatment and collateral for the Level 3 instruments.

The carrying amounts, including fair value adjustments previously recognized in acquisition purchase accounting and a fair value adjustment related to the Company’s interest rate swap fair value hedge (which is classified as Level 2 in the fair value hierarchy), and fair values of the financial instruments were as follows:

	Carrying		At Fair Value as of June 30, 2017
	Amount		Level 1		Level 2		Level 3		Total
Preferred stock with mandatory redemption requirements	$	11	$	—	$	—	$	14	$	14
Long-term debt (excluding capital lease obligations)		6,333		4,007		1,348		1,847		7,202

Preferred stock with mandatory redemption requirements	$	12	$	—	$	—	$	15	$	15
Long-term debt (excluding capital lease obligations)		6,320		3,876		1,363		1,805		7,044

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 operations and maintenance projects. The proceeds of these financings are held in escrow until the designated expenditures are incurred. Long-term restricted funds of $1 and $4 were included in other long-term assets as of June 30, 2017 and December 31, 2016, respectively.

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.

Deposits—Deposits include escrow funds and certain other deposits held in trust. The Company includes cash deposits in other current assets.

Mark-to-market derivative asset and liability—The Company utilizes fixed-to-floating interest-rate swaps, typically designated as fair-value hedges, to achieve a targeted level of variable-rate debt as a percentage of total debt. The Company also employs derivative financial instruments in the form of variable-to-fixed interest rate swaps and forward starting interest rate swaps, classified as economic hedges and cash flow hedges, respectively, 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—Other investments primarily represent money market funds used for active employee benefits. The Company includes other investments in other current assets.

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. 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.

New Accounting Standards (Policies)

6 Months Ended

Jun. 30, 2017

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]

New Accounting Standards

The Company adopted the following accounting standard on January 1, 2017:

Standard	Description	Date of Adoption	Application	Estimated Effect on the Consolidated Financial Statements (or Other Significant Matters)
Simplification of Employee Share-Based Payment Accounting	Simplified accounting and disclosure requirements for share-based payment awards. The updated guidance addresses simplification in areas such as: (i) the recognition of excess tax benefits and deficiencies; (ii) the classification of excess tax benefits and taxes paid on the Consolidated Statements of Cash Flows; (iii) election of an accounting policy for forfeitures; and (iv) the amount an employer can withhold to cover income taxes and still qualify for equity classification.	January 1, 2017	Modified retrospective for the recognition of excess tax benefits and deficiencies; full retrospective for the classification of excess tax benefits and taxes paid on the Consolidated Statements of Cash Flows	The adoption of this standard resulted in a cumulative effect to increase retained earnings by $21, with an offsetting decrease to deferred income taxes, net. Also, the adoption resulted in a net increase in cash flows from operating activities and a net decrease in cash flows from financing activities of $14 and $18 for the six months ended June 30, 2017 and 2016, respectively, on the Consolidated Statements of Cash Flows.

The following recently issued accounting standards are not yet required to be adopted by the Company as of June 30, 2017:

Standard	Description	Date of Adoption	Permitted Application	Estimated Effect on the Consolidated Financial Statements (or Other Significant Matters)
Revenue from Contracts with Customers	Changes the criteria for recognizing revenue from a contract with a customer. Replaces existing guidance on revenue recognition, including most industry specific guidance. The objective is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries and across capital markets.  The underlying principle is that an entity will recognize revenue to depict the transfer of goods and services to customers at an amount the entity expects to be entitled to in exchange for those goods or services.  The guidance also requires a number of disclosures regarding the nature, amount, timing and uncertainty of revenue and the related cash flows.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company substantially completed its evaluation of the requirements of the new standard based on current interpretations and does not expect there to be a change in the measurement or timing of revenue recognized. The Company continues to monitor for new authoritative and interpretative guidance, which upon release could impact the Company’s current evaluation. The Company plans to adopt the new standard on January 1, 2018 using the modified retrospective method.
Classification of Certain Cash Receipts and Cash Payments on the Statement of Cash Flows	Provides guidance on the presentation and classification in the statement of cash flows for the following cash receipts and payments: (i) debt prepayment or debt extinguishment costs; (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (iii) contingent consideration payments made after a business combination; (iv) proceeds from the settlement of insurance claims; (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (vi) distributions received from equity method investees; (vii) beneficial interests in securitization transactions and (viii) separately identifiable cash flows and application of the predominance principle.	January 1, 2018; early adoption permitted	Retrospective	The Company does not anticipate significant impacts on its consolidated statements of cash flows.
Presentation of Changes in Restricted Cash on the Statement of Cash Flows	Updates the accounting and disclosure guidance for the classification and presentation of changes in restricted cash on the statements of cash flows. The amended guidance requires that the statements of cash flows explain the change during the period in the total of cash, cash equivalents and amounts described as restricted cash or restricted cash equivalents. Restricted cash and restricted cash equivalents will now be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statements of cash flows.	January 1, 2018; early adoption permitted	Retrospective	The Company does not anticipate significant impacts on its consolidated statements of cash flows.
Clarifying the Definition of a Business	Updates the accounting guidance to clarify the definition of a business with the objective of assisting entities with evaluating whether transactions should be accounted for as acquisitions, or disposals, of assets or businesses.	January 1, 2018; early adoption permitted	Prospective	The update could result in more acquisitions being accounted for as asset acquisitions. The effect on the Company's consolidated financial statements will be dependent on the transactions executed by the Company subsequent to adoption.
Gains and Losses from the Derecognition of Nonfinancial Assets	Updated the guidance to clarify the accounting for gains and losses resulting from the derecognition of nonfinancial assets and partial sale of nonfinancial assets. The guidance also clarifies the definition of an in-substance nonfinancial asset.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company is evaluating the impact on its consolidated financial statements and related disclosures.
Presentation of Net Periodic Pension Cost and Net Periodic  Postretirement Benefit Cost	Updated authoritative guidance requires the service cost component of net periodic benefit cost to be presented in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. The remaining components of net periodic benefit cost are required to be presented separately from the service cost component in an income statement line item outside of operating income. Also, the guidance allows for only the service cost component to be eligible for capitalization. The updated guidance does not impact the accounting for net periodic benefit costs as regulatory assets or liabilities.	January 1, 2018; early adoption permitted	Retrospective for the presentation of service cost component; prospective for the capitalization of service cost component	The Company is evaluating the impact on its consolidated financial statements and related disclosures.
Accounting for Leases	Updated the accounting and disclosure guidance for leasing arrangements. Under this guidance, a lessee will be required to recognize the following for all leases, excluding short-term leases, at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the guidance, lessor accounting is largely unchanged.	January 1, 2019; early adoption permitted	Modified retrospective	The Company is evaluating the effect on its consolidated financial statements and related disclosures.
Simplification of Goodwill Impairment Testing	Updated authoritative guidance which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amendments in the update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying value exceeds the reporting unit's fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.	January 1, 2020; early adoption permitted	Prospective	The Company is considering early adopting this guidance for its next annual goodwill impairment test, which will occur during the fourth quarter of 2017. The Company does not expect the adoption to have a material impact on its consolidated financial statements or related disclosures.
Measurement of Credit Losses	Updated the accounting guidance on reporting credit losses for financial assets held at amortized cost basis and available-for-sale debt securities. Under this guidance, expected credit losses are required to be measured based on historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount of financial assets. Also, this guidance requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a direct write-down.	January 1, 2020; early adoption permitted	Modified retrospective	The Company is evaluating the impact on its consolidated financial statements and related disclosures, as well as the timing of adoption.
