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 March 31, 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 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	Effecton 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 $13 for the three months ended March 31, 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 March 31, 2017:

Standard	Description	Date of Adoption	Application	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 related cash flows.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company is evaluating the impact on the consolidated financial statements and related disclosures, as well as the transition method to be used to adopt the guidance. The Company is also considering the impacts of the new standard on its accounting for contributions in aid of construction. The Company does not expect to early adopt.
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 Company is evaluating the impact on the consolidated financial statements and related disclosures.
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 the 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 the 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 the consolidated financial statements, related disclosures, as well as the timing of adoption.

10

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 evaluating the impact on the consolidated financial statements and related disclosures, as well as the timing of adoption.
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 the consolidated financial statements and related disclosures, as well as the timing of adoption.

Note 3: Acquisitions

During the three months ended March 31, 2017, the Company closed on two water system acquisitions for a total aggregate purchase price under $1. Also, our Regulated Business made a non-escrowed deposit of $2 related to the acquisition of the McKeesport, Pennsylvania wastewater system which is expected to close in the fourth quarter of 2017.

On April 3, 2017, the Company acquired all of the outstanding capital stock of Shorelands Water Company, Inc. for total consideration of $33, in the form of approximately 0.4 shares of the Company’s common stock. Assets acquired, principally utility plant, totaled $26. Liabilities assumed totaled $19, including $5 of contributions in aid of construction, and assumed debt of $6. This acquisition will be recorded during the second quarter of 2017 and includes $27of goodwill, which will be reported in the Company’s Regulated Businesses segment. The preliminary price allocation related to this acquisition will be finalized once the valuation of assets acquired has been completed, no later than one year after the acquisition date.

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 7— 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 three months ended March 31, 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 March 31, 2017, there were 6.1 shares of common stock available for repurchase under the program.

Note 5: Long-Term Debt

The following long-term debt was retired through sinking fund provisions, optional redemptions or payment at maturity during the three months ended March 31, 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		2
Other American Water subsidiaries	Mandatorily redeemable preferred stock		8.49%	2036		1
Total retirements and redemptions					$	4

(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 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 a 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 these forward 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 the 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 recognized by the Company was de minimis for the three months ended March 31, 2017 and 2016.

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 instruments as economic hedges accounted for at fair value with gains or losses recognized in interest, net. The net gain recognized by the Company was de minimis for the three months ended March 31, 2017 and 2016.

No ineffectiveness was recognized for the three months ended March 31, 2017 and 2016 related to hedging instruments.

Note 6: Income Taxes

The Company’s effective income tax rate was35.9%and39.7%for thethree months ended March 31, 2017 and 2016, respectively. The effective income tax rate for the three months ended March 31, 2017 was impacted by a $5 tax benefitfrom the new accounting standard for employee share-based payment awards which was adopted in 2017. Under this updated guidance, tax benefits or shortfalls related to employee share-based payment awards are recognized in the provision for income taxes, whereas they previously were recorded as additional paid-in capital on the Consolidated Balance Sheets. 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 would increase the state income tax rate on the Company’s taxable income attributable to New York. Manufacturers in New York are taxed at a lower income tax rate, and this legislation eliminated the production of water as a qualified manufacturing activity. The effective date of the legislation is January 1, 2018 and this future increase in the New York tax rate will cause the Company to book a one-time adjustment during the second quarter of 2017, increasing its state accumulated deferred income tax liability.  An offsetting adjustment will be recorded to regulatory assets for the amount recoverable in future customer rates, with the remaining balance recorded to income tax expense.

Note 7: Pension and Other Postretirement Benefits

The following table provides the components of net periodic benefit costs:

Note 8: Commitments and Contingencies

Contingencies

The Company is routinely involved in legal actions incident to the normal conduct of its business. As of March 31, 2017, the Company has accrued approximately $138 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 8, 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 until June 6, 2017 and remains subject to further delay in light of the binding global agreement in principle described below. The Mass Litigation Panel has also stayed its proceedings until July 26, 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

14

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 March 31, 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. 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.

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.

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. 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 March 31, 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 this Note 8.

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 March 29, 2017, the Missouri Office of Public Counsel filed a Motion for Rehearing with the Missouri Supreme Court, which remains pending.

As a result of the Missouri Supreme Court’s decision, the Company has determined that, as of March 31, 2017, a loss associated with this matter is remote.

Note 10: 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 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 March 31, 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)		6,316		3,972		1,363		1,822		7,157
	Carrying		At Fair Value as of December 31, 2016
	Amount		Level 1		Level 2		Level 3		Total
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 $4 were included in other long-term assets as of March 31, 2017 and December 31, 2016.

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.

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.

18

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.

Note 11: Segment Information

The Company operates its businesses primarily through one reportable segment, the Regulated Businesses segment. The Company also operates businesses that provide a broad range of related and complementary water and wastewater services in non-regulated markets, which includes four operating segments that individually do not meet the criteria of a reportable segment. These four non-reportable operating segments are collectively presented as our “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 $93 million, or $0.52 per diluted share for the first quarter of 2017, an increase of 13% over the same period in 2016. This increase was primarily due to continued growth in our Regulated Businesses segment, largely attributable to additional authorized revenue driven by investment growth, acquisitions and organic growth, and a tax benefit associated with the new accounting standard requirements for stock-based compensation.

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 in the first three months of 2017 with respect to growth and improvement in our operational efficiency ratio is described below.

Growth—Infrastructure improvements, acquisitions and strategic capital investments

During the first three months of 2017, we made capital investments of approximately $242 million, the majority of which was in our Regulated Businesses, primarily to improve infrastructure. For the full year of 2017, our total capital investment, including acquisitions, is expected to be approximately $1.5 billion, most of which is allocated to improving infrastructure in our Regulated Businesses.  

20

Regulated acquisition growth included:

• Closed acquisitions of $38 million, adding approximately 13,000 customers through May 3, 2017. This includes the acquisition on April 3, 2017, of all of 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 provides water service to approximately 11,000 customers in Monmouth County, New Jersey. The assets acquired are owned by New Jersey-American Water Company, Inc.

• Pending acquisitions representing the addition of approximately 33,000 customers, including the September 9, 2016, asset purchase agreement signed by Pennsylvania-American Water Company to acquire substantially all of the wastewater collection and treatment system assets of the Municipal Authority of the City of McKeesport, Pennsylvania for approximately $156 million, subject to certain adjustments provided in the agreement. In connection with the execution of this agreement, a $7 million non-escrowed deposit has 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 in the fourth quarter of 2017.

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 March 31, 2017 was 34.6%, compared to 35.6% for the twelve months ended March 31, 2016. The improvement in the 2017 O&M efficiency ratio over this period was attributable to an increase in revenue.

Our adjusted O&M efficiency ratio is defined as our regulated O&M expenses divided by regulated operating revenues, where both O&M expenses and operating revenues were adjusted to eliminate purchased water expense. Additionally, from the O&M expenses, we excluded the allocable portion of non-O&M support services cost, mainly depreciation and general taxes that are reflected in the Regulated Businesses segment as O&M 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 the O&M efficiency ratio for the twelve months ended March 31, 2017, we have also excluded from O&M 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 the Company’s 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. The 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.

21

The following table provides the calculation and reconciliation that compares O&M 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 March 31, 2017, as compared to the same period in 2016:

Regulatory Matters

The table below provides rate authorizations which became effective during the three months ended March 31, 2017. The table depicts annualized incremental revenues, assuming a constant water sales volume, resulting from general rate cases and, infrastructure surcharge mechanisms that became effective during the period:

Pending and Filed Rate Cases

On April 3, 2017, our California subsidiary filed a cost of capital application requesting a return on equity of 10.8%. The results of this proceeding will not become effective until January 2018.  

On April 13, 2017, our New Jersey subsidiary filed for an infrastructure surcharge requesting additional revenues of $10 million.

22

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

In addition to the filings discussed above, we are awaiting final general rate case orders in three states requesting additional annualized revenue of $52 million. One of these states authorized interim rates under bond, subject to refund, which were put into effect in 2016. We are also awaiting approval in one state for a step rate and attrition rate increase of $8 million in both 2019 and 2020. There is no assurance that all or any portion of these requests will be granted.

Other Regulatory Matters

On April 5, 2017, Senate Bill 1492 impacting our Virginia subsidiary was approved and will become law later in 2017. The new law directs the Virginia State Corporation Commission to require water and wastewater utilities in any proceeding after July 1, 2017, to consolidate tariffs for each service statewide.

Other Tax Matters

On April 11, 2017, the State of New York enacted legislation that would increase the state income tax rate on our taxable income attributable to New York. Manufacturers in New York are taxed at a lower income tax rate, and this legislation eliminated the production of water as a qualified manufacturing activity. The effective date of the legislation is January 1, 2018 and this future increase in the New York tax rate will cause us to book a one-time adjustment during the second quarter of 2017, increasing our state accumulated deferred income tax liability.  An offsetting adjustment will be recorded to regulatory assets for the amount recoverable in future customer rates, with the remaining balance, preliminarily estimated to be between $5 million and $7 million, recorded to income tax expense.

Comparison of Consolidated Results of Operations

Operating revenues.For the three months ended March 31, 2017, operating revenues increased primarily due to a:

• $25 million increase in our Regulated Businesses segment principally due to authorized rate increases to fund infrastructure investment growth, acquisitions and organic growth, partially offset by lower demand and consumption when compared to the same period in 2016; and

• $11 million decrease in our Market-Based Businesses primarily due to lower revenue from capital upgrades in our Military Services Group as a result of the completion of a large project in mid-2016 at Fort Polk and reduced military base budgets. Partially offsetting this decrease were incremental revenues from our Homeowner Services Group from customer additions and price increases.

Operation and maintenance. For the three months ended March 31, 2017, operation and maintenance expense decreased principally due to a:

• $11 million decrease in our Market-Based Businesses attributable to lower capital upgrades in our Military Services Group corresponding with the decrease in operating revenues discussed above, partially offset by higher expenses in our Homeowner Services Group due to higher claims expense.

Depreciation and amortization. For the three months ended March 31, 2017, depreciation and amortization expense increased largely due to additional utility plant placed in service.

Other income (expenses).For the three months ended March 31, 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.  

Provision for income taxes. For the three months ended March 31, 2017, our provision for income taxes decreased principally due to the tax benefit recorded as a result of the new accounting standard for stock-based compensation.

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.

24

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

Regulated Businesses Segment

The following table summarizes certain financial information for our Regulated Businesses segment:

Billed water services volumes		73,419		73,433		(14	)		(0.0	)

For the three months ended March 31, 2017, operating revenues increased primarily due to a:

• $25 million increase from authorized rate increases, including infrastructure surcharges, to fund infrastructure investment growth in various states;

• $8 million increase resulting from water and wastewater acquisitions as well as organic growth in existing systems; and

• $7 million decrease in demand and consumption when compared to the same period in 2016.

25

Operation and maintenance. The following table summarizes information regarding the components of operation and maintenance expense:

	For the Three Months Ended March 31,
	2017		2016		Increase (Decrease)
(In millions)								%
Production costs	$	63	$	63	$	—			—

Other		12		11		1			9.1
Total	$	262	$	262	$	—			—

For the three months ended March 31, 2017, operation and maintenance expense was flat when compared to the same period in 2016. Variances related to individual components of operation and maintenance expense include a:

• $4 million decrease in customer billing and accounting due to a reduction in uncollectible expense primarily attributable to focused collection efforts; and

• $3 million increase in maintenance materials and supplies primarily due to increased tank painting costs, as well as the timing of specific maintenance activity in 2017 as compared to the same period in 2016;

Operating expenses, net. For the three months ended March 31, 2017, operating expenses, net increased primarily due to higher depreciation and amortization expense and general taxes expense of $9 million and $3 million, respectively. The increase in depreciation and amortization expense was driven by additional utility plant placed in service. The increase in general taxes is primarily due to higher gross receipts tax in New Jersey and higher property taxes in 2017 driven by investment growth.

For the three months ended March 31, 2017, operation and maintenance expense decreased primarily due to a:

• $16 million decrease in operating supplies and services resulting from lower capital upgrades in our Military Services Group, as discussed above, and focused cost management in Keystone; partially offset by a

• $5 million increase in maintenance services and supplies due principally 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 March 31, 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 March 31, 2017, the revolving credit facility supported $980 million 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.

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 a fixed rate of 2.67%.During the three months ended March 31, 2017, the fair value of our five forward starting swaps increased by $5 million due to higher 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 5—Long-Term Debt for further information.

27

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 Three Months Ended March 31,
	2017			2016
(In millions)
Net income	$	93		$	82
Add (less):
Non-cash activities (a)		189			177
Changes in working capital (b)		6			15
Pension and postretirement healthcare contributions		(11	)		(14	)
Net cash flows provided by operations	$	277		$	260

(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 three months ended March 31, 2017, the increase in cash flows from operating activities, as compared to the same period in 2016, is primarily due to an increase in net income after non-cash adjustments. The main factors contributing to 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. The increase in non-cash activities was mainly the result of an increase in depreciation and amortization attributable to infrastructure investment projects placed into service. The change in working capital was primarily the result of the following: (1) timing of accounts payable and accrued liabilities; and (2) change in other current assets and liabilities.

Cash Flows Used in Investing Activities

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

	For the Three Months Ended March 31,

Net cash flows used in investing activities	$	(288	)	$	(323	)

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

For the three months ended March 31, 2017, cash used in investing activities decreased primarily due to the timing of payments for the capital expenditures and acquisitions. We continue to expect investments of approximately $1.5 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, with $77 million expected to be incurred in 2017.

Net cash flows provided by financing activities	$	14		$	84

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

For the three months ended March 31, 2017, the decrease in cash flows provided by financing activities, as compared to the same period in 2016, is primarily due to incremental short-term borrowings in 2016 to fund a portion of the capital expenditures and acquisitions.

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 March 31, 2017:

(a) Includes amounts related to the revolving credit facility of Keystone Clearwater Solutions, LLC (“Keystone”), our water management solutions subsidiary. As of March 31, 2017, the total commitment under the Keystone revolving credit facility was $16 million, of which $9 million was available for borrowing, subject to compliance with a collateral base calculation.

The weighted-average interest rate on AWCC short-term borrowings for the three months ended March 31, 2017 and 2016 was approximately 1.02% and 0.74%, respectively.

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.

29

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 March 31, 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 March 31, 2017 are as follows:

Securities	Moody's Investors Service	Standard & Poor's Ratings Service
Senior unsecured debt	A3	A
Commercial paper	P2	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 March 1, 2017, we paid a cash dividend of $0.375 per share to our stockholders of record as of February 7, 2017.

On April 21, 2017, our Board of Directors declared a quarterly cash dividend payment of $0.415 per share payable on June 1, 2017 to stockholders of record as of May 5, 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.

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

30

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 $19 million increase or decrease in fair value for the three months ended March 31, 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 March 31, 2017.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 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 March 31, 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).

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The following information updates and amends the information provided in our Form 10-K in Part I, Item 3—Legal Proceedings. Capitalized terms used but not otherwise defined herein have the meanings set forth in our Form 10-K.

Alternative Water Supply in Lieu of Carmel River Diversions

Regional Desalination Project Litigation

On January 5, 2017, the parties to the consolidated action in San Francisco County Superior Court associated with the failure of the RDP participated in a CPUC-sponsored mediation that was unsuccessful in resolving the claims among them. On February 10, 2017, the Superior Court heard oral argument on the parties’ demurrers to certain of the claims raised in this litigation. On February 14, 2017, the court issued an order sustaining in part and overruling in part the demurrers. On March 1, 2017, the parties to this litigation, other than RMC, filed amended pleadings and a schedule for filing additional motions has been set.

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 million in under-collections in the water revenue adjustment mechanism/modified cost balancing account (the “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 million 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 $3.1 million to $178.9 million (calculated as a continuing violation dating back to 2000 and applying penalties of up to $20,000 per day until January 1, 2012 and penalties of up to $50,000 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.

Cal Am believes that the terms of the Joint Settlement Agreement are fair and reasonable, that its residential tariff administration is compliant with California Public Utilities Code and it is able to assert credible defenses against the CPUC’s allegations of wrongdoing and the associated penalties. Cal Am intends to vigorously defend itself in this proceeding against these allegations and the imposition of penalties; however, the ultimate outcome of this matter cannot be determined at this time.

West Virginia Elk River Freedom Industries Chemical Spill

Background

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 until June 6, 2017 and remains subject to further delay in light of the proposed settlement agreement discussed below. The Mass Litigation Panel has also stayed its proceedings until July 26, 2017.

32

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. 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.

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. WVAWC believes that the lawsuit is without merit and intends to vigorously contest the claims and allegations raised in the complaint.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A—Risk Factors in our Form 10-K, and in our other public filings, which could materially affect our business, financial condition or future results. There have been no material changes from risk factors previously disclosed in Part I, Item 1A—Risk Factors in our Form 10-K.

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 following table provides a summary of information about the shares of common stock purchased by the Company during the three months ended March 31, 2017:

	Total Number of Shares Purchased		Average Price Paid per Share (a)		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs(b)		Maximum Number of Shares Available to be Purchased Under the Plan or Program
January 1 - January 31, 2017		—		—		—		6,750,000
February 1 - February 28, 2017		—		—		—		6,750,000
March 1 - March 31, 2017		700,000	$	77.44		700,000		6,050,000
Total		700,000	$	77.44		700,000

(a) Average price paid per share includes brokerage fees and commissions incurred by the Company in connection with these repurchases.

(b) From April 1, 2015, the date repurchases under the anti-dilutive stock repurchase program commenced, through March 31, 2017, the Company repurchased an aggregate of 3,950,000 shares of common stock under the program.

EX-10.1.1

Exhibit 10.1.1

AMERICAN WATER WORKS COMPANY, INC.
2007 OMNIBUS EQUITY COMPENSATION PLAN
RESTRICTED STOCK UNIT GRANT

This RESTRICTED STOCK UNIT GRANT, dated as of February 14, 2017 (the “Date of Grant”), is delivered by American Water Works Company, Inc. (the “Company”) to _____________________ (the “Participant”).

RECITALS

WHEREAS, the Committee (as defined in the American Water Works Company, Inc. 2007 Omnibus Equity Compensation Plan (the “Plan”)) has adopted a 2017 Long Term Performance Plan (“2017 LTPP”) pursuant to which designated employees will be granted equity awards (collectively, the “Equity Award”) for shares of Common Stock of the Company, par value $0.01 per share, (the “Company Stock”);

WHEREAS, the Equity Award is comprised of three separate grants: a restricted stock unit and two performance stock unit grants;

WHEREAS, the Committee has determined that the Participant is eligible to participate in the 2017 LTPP and to grant the Participant an Equity Award under the 2017 LTPP; and

WHEREAS, the Committee has determined that the restricted stock unit portion of the Equity Award granted pursuant to the 2017 LTPP to the Participant shall be issued under the Plan and the terms and conditions of such restricted stock unit shall be memorialized in this grant (the “Grant”).

NOW, THEREFORE, the parties to this Grant, intending to be legally bound hereby, agree as follows:

1.Grant of Restricted Stock Units. Subject to the terms and conditions set forth in this Grant and the Plan, the Company hereby grants to the Participant _______ units (the “Restricted Stock Units”). Each unit (a “Unit”) shall be a phantom right and shall be equivalent to one share of Company Stock on the applicable Redemption Date (as defined below).

2.Restricted Stock Unit Account. The Company shall establish and maintain a Restricted Stock Unit account as a bookkeeping account on its records (the “Restricted Stock Unit Account”) for the Participant and shall record in such Restricted Stock Unit Account the number of Restricted Stock Units granted to the Participant. The Participant shall not have any interest in any fund or specific assets of the Company by reason of this grant or the Restricted Stock Unit Account established for the Participant.

3.Vesting.

(a)Except as provided in subparagraph (c) below, the Restricted Stock Units shall vest on the following dates (each a “Service Date”), provided the Participant continues to be employed by, or providing service to, the Employer (as defined in the Plan) from the Date of Grant through the applicable Service Date:

Service Date	Units Vesting
January 1, 2018	1/3
January 1, 2019	1/3
January 1, 2020	1/3

The vesting of the Restricted Stock Units is cumulative, but shall not exceed 100% of the Units subject to the Restricted Stock Units.  If the foregoing schedule would produce fractional Units, the number of Units for which the Restricted Stock Units becomes vested on a Service Date  shall be rounded down to the nearest whole Unit.  The Restricted Stock Units shall become vested with respect to 100% of the Units subject to the Restricted Stock Units on January 1, 2020, if the Participant is employed by, or providing service to, the Employer on such date.

(b)Subject to subparagraph (c) below, if at any time prior to January 1, 2020, the Participant’s employment or service with the Employer terminates for any reason, including death or disability, then all of the unvested Restricted Stock Units shall be immediately forfeited and the Participant shall not have any rights with respect to the vesting or the redemption of any portion of the Restricted Stock Unit.

(c)If at any time prior to January 1, 2020, but while the Participant is employed by or providing service to the Employer, a Change of Control (as defined below) occurs, then the portion of the Restricted Stock Units that have not yet vested as provided in subparagraph 3(a) above shall become fully vested on the date of the Change of Control (the “Change of Control Date”). For purposes of this Agreement, the term “Change of Control” shall mean as such term is defined in the Plan, except that a Change of Control shall not be deemed to have occurred for purposes of this Agreement unless the event constituting the Change of Control constitutes a change in the ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, within the meaning of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and its corresponding regulations.  For the avoidance of doubt, if the Change of Control does not constitute a permitted change in control event under section 409A of the Code, then the Restricted Stock Unit shall not vest on the occurrence of the Change of Control.

4.Redemption. Unless an election is made pursuant to Paragraph 5 below, the Restricted Stock Units that have become vested pursuant to Paragraph 3 shall be redeemed by the Company on the earlier of the (i) applicable Service Date or (ii) the Change of Control Date, (the date of redemption is hereinafter referred to as the “Redemption Date”).  As soon as administratively practicable following the applicable Redemption Date, but not later than forty-five (45) days

2

following the Redemption Date, (or, if applicable, the Deferred Date, as defined in Paragraph 5 below), all Restricted Stock Units that become vested pursuant to Paragraph 3 above shall be redeemed and converted to an equivalent number of shares of Company Stock, and the Participant shall receive a single sum distribution of such shares of Company Stock, which shall be issued under the Plan.  

5.Deferrals. The Participant may make an irrevocable election to defer the Redemption Date (or further defer the Deferred Date (as defined below), if applicable) of any of the Restricted Stock Units that vest, plus dividend equivalents earned on such Restricted Stock Units as described in Paragraph 6 below, to a later date, provided that (i) the election shall not take effect until at least twelve (12) months after the date on which the election is made, (ii) the new Redemption Date cannot be earlier than five (5) years from the original Redemption Date under Paragraph 4 above (or five (5) years from the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made), and (iii) the election must be made no less than twelve (12) months prior to the date of the Redemption Date (twelve (12) months prior to the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made). To defer the Redemption Date, the Participant must complete the deferral election form provided to the Participant by the Committee.  If the Participant desires to make a further deferral, the Participant must make such election on a separate form provided by the Committee for such purpose.  Any such election shall be made in accordance with section 409A of the Code and any corresponding guidance and regulations issued under section 409A of the Code.  Notwithstanding a Participant’s election pursuant to this Paragraph, if the Change of Control Date occurs prior to the Deferred Date, the redemption of the Participant’s Restricted Stock Units, plus corresponding dividend equivalents, will be the Change of Control Date.  If a Redemption Date is delayed one or more times pursuant to this Paragraph 5, the new Redemption Date shall be referred to as the “Deferred Date.”

6.Dividend Equivalents. Until the Redemption Date (or the Deferred Date, if elected), if any dividends are paid with respect to the shares of Company Stock, the Company shall credit to a dividend equivalent account (the “Dividend Equivalent Account”) the value of the dividends that would have been distributed if the Restricted Stock Units credited to the Participant’s Restricted Stock Unit Account as of the date of payment of any such dividend were shares of Company Stock. On the Redemption Date (or the Deferred Date, if applicable), the Company shall pay to the Participant a lump sum cash payment equal to the value of the dividends credited to the Participant’s Dividend Equivalent Account; provided, however, that any dividends that were credited to the Participant’s Dividend Equivalent Account that are attributable to Units that have been forfeited as provided in Paragraph 3 above shall be forfeited and not payable to the Participant. No interest shall accrue on any dividend equivalents credited to the Participant’s Dividend Equivalent Account.  

7.Change of Control.  Except as set forth in Paragraph 3(c) of this Grant, the provisions set forth in the Plan applicable to a Change of Control (as defined in the Plan) shall apply to the Restricted Stock Units, and, in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan and is consistent with the requirements of section 409A of the Code.

8.Acknowledgment by Participant. By accepting this Grant, the Participant acknowledges that with respect to any right to redemption or distribution pursuant to this Grant, the Participant

3

is and shall be an unsecured general creditor of the Company without any preference as against other unsecured general creditors of the Company, and the Participant hereby covenants for himself or herself, and anyone at any time claiming through or under the Participant not to claim any such preference, and hereby disclaims and waives any such preference which may at any time be at issue, to the fullest extent permitted by applicable law.

9.Restrictions on Issuance or Transfer of Shares of Company Stock.

(a)To the extent permitted by Code section 409A, the obligation of the Company to deliver shares of Company Stock upon the redemption of the Restricted Stock Units shall be subject to the condition that if at any time the Committee shall determine in its discretion that the listing, registration or qualification of the shares of Company Stock upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance of shares of Company Stock, the shares of Company Stock may not be issued in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Committee.  

(b)The issuance of shares of Company Stock and the payment of cash to the Participant pursuant to this Grant is subject to any applicable taxes and other laws or regulations of the United States or of any state having jurisdiction thereof.

(c)As a condition to receive any shares of Company Stock on the Redemption Date (or the Deferred Date, if applicable), the Participant agrees:

(i) to be bound by, and to comply with, the Company’s policies and practices (as they may be in effect from time to time) regarding the restrictions or limitations on the transfer of such shares, and understands that the Participant may be restricted or prohibited at any time and from time to time from selling, transferring, pledging, donating, assigning, margining, mortgaging, hypothecating or otherwise encumbering the shares in accordance with such policies and practices, including without limitation the Company’s Personal Securities and Insider Trading Policy; and

(ii)that the shares of Company Stock obtained by the Participant upon the redemption of the Restricted Stock Units shall be subject to the guidelines and restrictions set forth in the Company’s Executive Stock Ownership Guidelines and Executive Stock Retention Requirements, effective as of March 4, 2015 (and as they may be amended, restated, supplemented and interpreted) and any applicable clawback or recoupment policies and other policies that may be implemented by the Company’s Board of Directors or a duly authorized committee thereof, from time to time.

10.Participant Undertaking.  The Participant agrees to take whatever additional actions and execute whatever additional documents the Company may in its reasonable judgment deem necessary or advisable in order to carry out or  one or more of the obligations or restrictions imposed on the Participant pursuant to the provisions of this Grant.

11.Grant Subject to Plan Provisions. This Grant is made pursuant to the Plan, the terms of which are incorporated herein by reference, and in all respects shall be interpreted in accordance with the Plan. In the event of any contradiction, distinction or difference between this Grant and the terms of the Plan, the terms of the Plan will control. Except as otherwise defined in this Grant, capitalized terms used in this Grant shall have the meanings set forth in the Plan. This Grant is subject to the interpretations, regulations and determinations concerning the Plan established from time to time by the Committee in accordance with the provisions of the Plan, including, but not limited to, provisions pertaining to (a) rights and obligations with respect to withholding taxes, (b) the registration, qualification or listing of the shares of Company Stock, (c) changes in capitalization of the Company, and (d) other requirements of applicable law. The Committee shall have the authority to interpret and construe this Grant pursuant to the terms of the Plan, its decisions shall be conclusive as to any questions arising hereunder.   By accepting this Grant, the Participant agrees (i) to be bound by the terms of the Plan and this Grant,  (ii) to be bound by the determinations and decisions of the Committee with respect to this Grant, the Plan and the Participant’s rights to benefits under this Grant and the Plan, and (iii) that all such determinations and decisions of the Committee shall be binding on the Participant, his or her beneficiaries and any other person having or claiming an interest under this Grant and the Plan on behalf of the Participant.

12.No Rights as Stockholder. The Participant shall not have any rights as a stockholder of the Company, including the right to any cash dividends (except as provided in Paragraph 6), or the right to vote, with respect to any Restricted Stock Units.

13.No Rights to Continued Employment or Service. This Grant shall not confer upon the Participant any right to be retained in the employment or service of the Employer and shall not interfere in any way with the right of the Employer to terminate the Participant’s employment or service at any time. The right of the Employer to terminate at will the Participant’s employment or service at any time for any reason is specifically reserved.

14.Assignment and Transfers. No Restricted Stock Units or dividend equivalents awarded to the Participant under this Grant may be transferred, assigned, pledged, or encumbered by the Participant and a Restricted Stock Unit shall be redeemed and a dividend equivalent distributed during the lifetime of the Participant only for the benefit of the Participant. Any attempt to transfer, assign, pledge, or encumber the Restricted Stock Unit or dividend equivalent by the Participant shall be null, void and without effect. The rights and protections of the Company hereunder shall extend to any successors or assigns of the Company.  This Grant may be assigned by the Company without the Participant’s consent.  

15.Withholding. The Participant shall be required to pay to the Employer, or make other arrangements satisfactory to the Employer to provide for the payment of, any federal, state, local or other taxes that the Employer is required to withhold with respect to the grant, vesting and redemption of the Restricted Stock Units and payment of dividend equivalents. Any tax withholding obligation of the Employer with respect to the redemption of the Restricted Stock Units may, at the Committee’s discretion, be satisfied by having shares of Company Stock withheld, up to an amount that does not exceed the minimum applicable withholding tax rate for federal (including FICA), state, local and other tax liabilities.

16.Effect on Other Benefits. The value of shares of Company Stock and dividend equivalents distributed with respect to the Restricted Stock Units shall not be considered eligible earnings for purposes of any other plans maintained by the Company or the Employer. Neither shall such value be considered part of the Participant’s compensation for purposes of determining or calculating other benefits that are based on compensation, such as life insurance.

17.Applicable Law. The validity, construction, interpretation and effect of this Grant shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the conflicts of laws provisions thereof.

19.Taxation; Code Section 409A. As applicable, this Grant is intended to comply with the requirements of section 409A of the Code and shall be interpreted and administered in accordance with Code section 409A.  Notwithstanding any provision to the contrary herein, if the Restricted Stock Units constitute “deferred compensation” under section 409A of the Code, distributions made with respect to this Grant may only be made in a manner and upon an event permitted by Code section 409A.  To the extent that any provision of the Grant would cause a conflict with the requirements of Code section 409A, or would cause the administration of the Grant to fail to satisfy the requirements of Code section 409A, such provision shall, to the extent practicable if permitted by applicable law, be deemed null and void.  In the event that it is determined not feasible to void a provision of this Grant, such provision shall be construed in a manner as to comply with the Code section 409A requirements.

Exhibit 10.1.2

AMERICAN WATER WORKS COMPANY, INC.
2007 OMNIBUS EQUITY COMPENSATION PLAN
RESTRICTED STOCK UNIT GRANT

This RESTRICTED STOCK UNIT GRANT, dated as of February 14, 2017 (the “Date of Grant”), is delivered by American Water Works Company, Inc. (the “Company”) to ________________ (the “Participant”).

RECITALS

WHEREAS, the Committee (as defined in the American Water Works Company, Inc. 2007 Omnibus Equity Compensation Plan (the “Plan”)) has adopted a 2017 Long Term Performance Plan (“2017 LTPP”) pursuant to which designated employees will be granted equity awards (collectively, the “Equity Award”) for shares of Common Stock of the Company, par value $0.01 per share, (the “Company Stock”);

WHEREAS, the Equity Award is comprised of three separate grants:  a restricted stock unit and two performance stock unit grants;

WHEREAS, the Committee has determined that the Participant is eligible to participate in the 2017 LTPP and to grant the Participant an Equity Award under the 2017 LTPP; and

WHEREAS, the Committee has determined that the restricted stock unit portion of the Equity Award granted pursuant to the 2017 LTPP to the Participant shall be issued under the Plan and the terms and conditions of such restricted stock unit shall be memorialized in this grant (the “Grant”).

NOW, THEREFORE, the parties to this Grant, intending to be legally bound hereby, agree as follows:

1.Grant of Restricted Stock Units. Subject to the terms and conditions set forth in this Grant and the Plan, the Company hereby grants to the Participant ________ units (the “Restricted Stock Units”). Each unit (a “Unit”) shall be a phantom right and shall be equivalent to one share of Company Stock on the applicable Redemption Date (as defined below).

2.Restricted Stock Unit Account. The Company shall establish and maintain a Restricted Stock Unit account as a bookkeeping account on its records (the “Restricted Stock Unit Account”) for the Participant and shall record in such Restricted Stock Unit Account the number of Restricted Stock Units granted to the Participant. The Participant shall not have any interest in any fund or specific assets of the Company by reason of this grant or the Restricted Stock Unit Account established for the Participant.

3. Vesting.

(a)Except as provided in subparagraph (c) below, the Restricted Stock Units shall vest on the following dates (each a “Service Date”), provided the Participant continues to be employed by, or providing service to, the Employer (as defined in the Plan) from the Date of Grant through the applicable Service Date:

Service Date	Units Vesting
January 1, 2018	1/3
January 1, 2019	1/3
January 1, 2020	1/3

(b)The vesting of the Restricted Stock Units is cumulative, but shall not exceed 100% of the Units subject to the Restricted Stock Units.  If the foregoing schedule would produce fractional Units, the number of Units for which the Restricted Stock Units becomes vested on a Service Date shall be rounded down to the nearest whole Unit.  The Restricted Stock Units shall become vested with respect to 100% of the Units subject to the Restricted Stock Units on January 1, 2020, if the Participant is employed by, or providing service to, the Employer on such date.

(c)Subject to subparagraph (d) below, if at any time prior to January 1, 2020, the Participant’s employment or service with the Employer terminates for any reason, including death or disability, then all of the unvested Restricted Stock Units shall be immediately forfeited and the Participant shall not have any rights with respect to the vesting or the redemption of any portion of the Restricted Stock Unit.

(d)If, on or after January 1, 2018, but prior to January 1, 2020, the Participant’s employment or service with the Employer terminates on account of Normal Retirement (as defined below), the portion of the Restricted Stock Units that have not yet vested as provided in subparagraph 3(a) above shall become fully vested on the date of the Participant’s termination of employment or service on account of Normal Retirement.  For purposes of this Grant, the term (i) “Normal Retirement” shall mean termination of employment or service with the Employer (other than for Cause (as defined below)) after the Participant has attained age sixty-two (62) and five (5) total years of employment or service with the Employer and (ii) “Cause” shall mean a finding by the Committee that the Participant (i) has breached his or her employment or service contract with the Employer, if any; (ii) has engaged in disloyalty to the Employer including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty; (iii) has disclosed trade secrets or confidential information of the Employer to persons not entitled to receive such information; (iv) has breached any written noncompetition or nonsolicitation agreement between the Participant and the Employer; or (v) has engaged in such other behavior detrimental to the interests of the Employer as the Committee determines.

(e)If at any time prior to January 1, 2020, but while the Participant is employed by or providing service to the Employer, a Change of Control (as defined below) occurs, then the portion

2

of the Restricted Stock Units that have not yet vested as provided in subparagraph 3(a) above shall become fully vested on the date of the Change of Control (the “Change of Control Date”). For purposes of this Agreement, the term “Change of Control” shall mean as such term is defined in the Plan, except that a Change of Control shall not be deemed to have occurred for purposes of this Agreement unless the event constituting the Change of Control constitutes a change in the ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, within the meaning of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and its corresponding regulations.  For the avoidance of doubt, if the Change of Control does not constitute a permitted change in control event under section 409A of the Code, then the Restricted Stock Unit shall not vest on the occurrence of the Change of Control.

4.Redemption. Unless an election is made pursuant to Paragraph 5 below, the Restricted Stock Units that have become vested pursuant to Paragraph 3 shall be redeemed by the Company on the earlier of the (i) applicable Service Date or (ii) the Change of Control Date, (the date of redemption is hereinafter referred to as the “Redemption Date”).  As soon as administratively practicable following the applicable Redemption Date, but not later than forty-five (45) days following the Redemption Date, (or, if applicable, the Deferred Date, as defined in Paragraph 5 below), all Restricted Stock Units that become vested pursuant to Paragraph 3 above shall be redeemed and converted to an equivalent number of shares of Company Stock, and the Participant shall receive a single sum distribution of such shares of Company Stock, which shall be issued under the Plan.  For purposes of clarity, if any Restricted Stock Units become vested pursuant to subparagraph 3(d) above as a result of termination of employment or service with the Employer on account of Normal Retirement, the Redemption Date for such vested Restricted Stock Units shall be the applicable Service Date or Change of Control Date to which such Restricted Stock Units would have been redeemed if the Participant had remained in the employment or service of the Employer (i.e., the Redemption Date continues to be the originally scheduled Service Date as provided in subparagraph 3(a) above or the Change of Control Date, if earlier, and is not accelerated to an earlier Service Date or to the date on which the termination of employment or service occurs).  

5.Deferrals. The Participant may make an irrevocable election to defer the Redemption Date (or further defer the Deferred Date (as defined below), if applicable) of any of the Restricted Stock Units that vest, plus dividend equivalents earned on such Restricted Stock Units as described in Paragraph 6 below, to a later date, provided that (i) the election shall not take effect until at least twelve (12) months after the date on which the election is made, (ii) the new Redemption Date cannot be earlier than five (5) years from the original Redemption Date under Paragraph 4 above (or five (5) years from the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made), and (iii) the election must be made no less than twelve (12) months prior to the date of the Redemption Date (twelve (12) months prior to the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made). To defer the Redemption Date, the Participant must complete the deferral election form provided to the Participant by the Committee.  If the Participant desires to make a further deferral, the Participant must make such election on a separate form provided by the Committee for such purpose.  Any such election shall be made in accordance with section 409A of the Code and any corresponding guidance and regulations issued under section 409A of the Code.  Notwithstanding a Participant’s election pursuant to this Paragraph, if the Change of Control Date occurs prior to the Deferred Date, the redemption of the Participant’s Restricted Stock Units, plus corresponding dividend equivalents,

3

will be the Change of Control Date.  If a Redemption Date is delayed one or more times pursuant to this Paragraph 5, the new Redemption Date shall be referred to as the “Deferred Date.”

6.Dividend Equivalents. Until the Redemption Date (or the Deferred Date, if elected), if any dividends are paid with respect to the shares of Company Stock, the Company shall credit to a dividend equivalent account (the “Dividend Equivalent Account”) the value of the dividends that would have been distributed if the Restricted Stock Units credited to the Participant’s Restricted Stock Unit Account as of the date of payment of any such dividend were shares of Company Stock. On the Redemption Date (or the Deferred Date, if applicable), the Company shall pay to the Participant a lump sum cash payment equal to the value of the dividends credited to the Participant’s Dividend Equivalent Account; provided, however, that any dividends that were credited to the Participant’s Dividend Equivalent Account that are attributable to Units that have been forfeited as provided in Paragraph 3 above shall be forfeited and not payable to the Participant. No interest shall accrue on any dividend equivalents credited to the Participant’s Dividend Equivalent Account.  

7.Change of Control. Except as set forth in Paragraph 3(d) of this Grant, the provisions set forth in the Plan applicable to a Change of Control (as defined in the Plan) shall apply to the Restricted Stock Units, and, in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan and is consistent with the requirements of section 409A of the Code.

8.Acknowledgment by Participant. By accepting this Grant, the Participant acknowledges that with respect to any right to redemption or distribution pursuant to this Grant, the Participant is and shall be an unsecured general creditor of the Company without any preference as against other unsecured general creditors of the Company, and the Participant hereby covenants for himself or herself, and anyone at any time claiming through or under the Participant not to claim any such preference, and hereby disclaims and waives any such preference which may at any time be at issue, to the fullest extent permitted by applicable law.

9. Restrictions on Issuance or Transfer of Shares of Company Stock.

(a)To the extent permitted by Code section 409A, the obligation of the Company to deliver shares of Company Stock upon the redemption of the Restricted Stock Units shall be subject to the condition that if at any time the Committee shall determine in its discretion that the listing, registration or qualification of the shares of Company Stock upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance of shares of Company Stock, the shares of Company Stock may not be issued in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Committee.  

(b)The issuance of shares of Company Stock and the payment of cash to the Participant pursuant to this Grant is subject to any applicable taxes and other laws or regulations of the United States or of any state having jurisdiction thereof.

4

(c)As a condition to receive any shares of Company Stock on the Redemption Date (or the Deferred Date, if applicable), the Participant agrees:

(i)to be bound by, and to comply with, the Company’s policies and practices (as they may be in effect from time to time) regarding the restrictions or limitations on the transfer of such shares, and understands that the Participant may be restricted or prohibited at any time and from time to time from selling, transferring, pledging, donating, assigning, margining, mortgaging, hypothecating or otherwise encumbering the shares in accordance with such policies and practices, including without limitation the Company’s Personal Securities and Insider Trading Policy; and

(ii)that the shares of Company Stock obtained by the Participant upon the redemption of the Restricted Stock Units shall be subject to the guidelines and restrictions set forth in the Company’s Executive Stock Ownership Guidelines and Executive Stock Retention Requirements, effective as of March 4, 2015 (and as they may be amended, restated, supplemented and interpreted) and any applicable clawback or recoupment policies and other policies that may be implemented by the Company’s Board of Directors or a duly authorized committee thereof, from time to time.

10.Participant Undertaking.  The Participant agrees to take whatever additional actions and execute whatever additional documents the Company may in its reasonable judgment deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on the Participant pursuant to the provisions of this Grant.  

11.Grant Subject to Plan Provisions. This Grant is made pursuant to the Plan, the terms of which are incorporated herein by reference, and in all respects shall be interpreted in accordance with the Plan. In the event of any contradiction, distinction or difference between this Grant and the terms of the Plan, the terms of the Plan will control. Except as otherwise defined in this Grant, capitalized terms used in this Grant shall have the meanings set forth in the Plan. This Grant is subject to the interpretations, regulations and determinations concerning the Plan established from time to time by the Committee in accordance with the provisions of the Plan, including, but not limited to, provisions pertaining to (a) rights and obligations with respect to withholding taxes, (b) the registration, qualification or listing of the shares of Company Stock, (c) changes in capitalization of the Company, and (d) other requirements of applicable law. The Committee shall have the authority to interpret and construe this Grant pursuant to the terms of the Plan, its decisions shall be conclusive as to any questions arising hereunder.   By accepting this Grant, the Participant agrees (i) to be bound by the terms of the Plan and this Grant,  (ii) to be bound by the determinations and decisions of the Committee with respect to this Grant, the Plan and the Participant’s rights to benefits under this Grant and the Plan, and (iii) that all such determinations and decisions of the Committee shall be binding on the Participant, his or her beneficiaries and any other person having or claiming an interest under this Grant and the Plan on behalf of the Participant.

12.No Rights as Stockholder. The Participant shall not have any rights as a stockholder of the Company, including the right to any cash dividends (except as provided in Paragraph 6), or the right to vote, with respect to any Restricted Stock Units.

5

13.No Rights to Continued Employment or Service.

14.Assignment and Transfers. No Restricted Stock Units or dividend equivalents awarded to the Participant under this Grant may be transferred, assigned, pledged, or encumbered by the Participant and a Restricted Stock Unit shall be redeemed and a dividend equivalent distributed during the lifetime of the Participant only for the benefit of the Participant.

EX-10.2.1

Exhibit 10.2.1 A

(No Special Retirement Vesting)

AMERICAN WATER WORKS COMPANY, INC.
2007 OMNIBUS EQUITY COMPENSATION PLAN
PERFORMANCE STOCK UNIT GRANT

This PERFORMANCE STOCK UNIT GRANT, dated as of February 14, 2017, (the “Date of Grant”), is delivered by American Water Works Company, Inc. (the “Company”) to ______________ (the “Participant”).

RECITALS

WHEREAS, the Committee (as defined in the American Water Works Company, Inc. 2007 Omnibus Equity Compensation Plan (the “Plan”)) has adopted a 2017 Long Term Performance Plan (“2017 LTPP”) pursuant to which designated employees will be granted equity awards (collectively, the “Equity Award”) for shares of Common Stock of the Company, par value $0.01 per share, (the “Company Stock”);

WHEREAS, the Equity Award is comprised of three separate grants: a restricted stock unit and two performance stock unit grants;

WHEREAS, the Committee has determined that the Participant is eligible to participate in the 2017 LTPP and to grant the Participant an Equity Award under the 2017 LTPP; and

WHEREAS, the Committee has determined that the performance stock unit portion of the Equity Award granted to the Participant pursuant to the 2017 LTPP shall be issued under the Plan, and the terms and conditions of the performance stock unit grant that may be earned based on the performance goal relating to the Company’s Total Stockholder Return shall be memorialized in this grant (the “Grant”).

NOW, THEREFORE, the parties to this Grant, intending to be legally bound hereby, agree as follows:

1.Grant of Performance Stock Units. Subject to the terms and conditions set forth in this Grant and the Plan, the Company hereby grants to the Participant _____________ performance stock units (the “Performance Units”). The Performance Units are contingently awarded and will be earned and distributable if and only to the extent that the performance goal and other conditions set forth in this Grant are met. Each Performance Unit shall be a phantom right and shall be equivalent to one share of Company Stock on the applicable payment date, as described in Paragraph 5 below. The number of Performance Units set forth above is equal to the target number of shares of Company Stock that the Participant will earn for 100% achievement of the performance goal described in Paragraph 3 below (the “Target Award”).

2.Performance Unit Account. The Company shall establish and maintain a Performance Unit account as a bookkeeping account on its records (the “Performance Unit Account”) for the Participant and shall record in such Performance Unit Account the number of Performance Units granted to the Participant.  The Participant shall not have any interest in any fund or specific assets of the Company by reason of this grant or the Performance Unit Account established for the Participant.

3.Performance Goal.

(a)Unless a Change of Control (as defined below) occurs prior to the end of Performance Period (as defined below), the distribution of the shares of Company Stock attributable to the Performance Units is contingent upon achievement of the performance goal described in subparagraph (b) below for the Performance Period and the Participant satisfying the continuation of employment and service with the Employer (as defined in the Plan) requirement described in Paragraph 4 below.  

(b)The Company’s Total Stockholder Return (“TSR”) (as described in subparagraph (c) below) will be compared to the TSR of the Peer Group companies set forth in Exhibit A attached hereto over the Performance Period (as defined below). The actual number of Performance Units the Participant earns may be greater or less than the Target Award, or even zero, based on the Company’s TSR percentile ranking relative to the TSR performance of the companies in the Peer Group, as follows:

Level of Achievement	Percentile Ranking Relative to Peer Group	Percentage of Target Award Earned
Maximum	90%	200%
Target	50%	100%
Threshold	25%	25%

If the Company’s actual TSR performance is between measuring points, the number of Performance Units the Participant earns will be interpolated. If the Company’s actual TSR performance is below the threshold, no Performance Units will be earned and all of Performance Units will be forfeited. If the Company’s actual TSR performance is greater than the maximum, only the maximum number of Performance Units will be earned.

(c)TSR represents stock price performance and dividend accumulation over the Performance Period for the Company and Peer Group. For purposes of this calculation, the initial stock price and the ending stock price are determined using the twenty (20) day average stock price for December 31, 2016, and December 31, 2019, as applicable. The twenty (20) day average stock price is the average of the daily closing stock prices for the twenty (20) trading days that end on the applicable December 31. If December 31 is not a trading day, the closing stock price on the first trading day prior to December 31 shall be used. To determine stock price performance, each closing stock price shall be adjusted by a dividend adjustment factor. The dividend adjustment factor takes into account each per share dividend paid for the Performance Period as well as the effect of any appreciation in stock price by reason of deeming the dividend to be reinvested in the stock.  Dividend adjusted stock prices shall be obtained from Bloomberg. The dividend adjusted price obtained from Bloomberg provides the closing price for the requested day, week, or month, adjusted for all applicable splits and dividend distributions.  At the end of the Performance Period, the TSR for the Company, and for each company in the Peer Group, shall be determined pursuant to the following formula:

TSR = (Dividend Adjusted Ending Stock Price – Dividend Adjusted Initial Stock Price)

Dividend Adjusted Initial Stock Price

2

The result shall be rounded to the nearest hundredth of one percent (.01%).

(d)As soon as administratively practicable following the end of the Performance Period (as defined in Section 3(f) below), the Committee will determine whether and to what extent the performance goal has been met and certify the number of Performance Units the Participant has earned, if any.  Except as described in Paragraph 4 below, the Participant must be employed by, or providing service to, the Employer on the last day of the Performance Period in order to earn the Performance Units.

(e)If a Change of Control occurs prior to the end of the Performance Period, then the Performance Period will end on the date of the Change of Control and the Performance Units will be deemed earned at the Target Award level as of the date of the Change of Control (the “Change of Control Date”). For purposes of this Grant, the term “Change of Control” shall mean as such term is defined in the Plan, except that a Change of Control shall not be deemed to have occurred for purposes of this Grant unless the event constituting the Change of Control constitutes a change in ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, within the meaning of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and its corresponding regulations.

(f)For purposes of this Grant, the term “Performance Period” shall mean the three (3)-year period beginning on January 1, 2017 and ending December 31, 2019, and the term “Peer Group” shall mean those companies included in Exhibit A as of January 1, 2017.  If at any time during the Performance Period a company in the Peer Group is no longer a publicly traded entity, such company shall be removed from the Peer Group as of January 1 of the year in which the company is no longer publicly traded.

4.Termination of Employment or Service.

(a)If, at least one year after the beginning of the Performance Period, but prior to the end of the Performance Period, the Participant ceases to be employed by, or provide service to, the Employer on account of any reason other than a termination for Cause (as defined below), the Participant will earn a pro-rata portion of the Performance Units, if the performance goal and the requirements of this Grant are met as of the last day of the Performance Period. The pro-rata portion earned will be equal to the number of Performance Units that would have been earned if the Participant had remained employed through the last day of the Performance Period, multiplied by a fraction, which fraction shall be equal to (i) 1/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2018, but prior to January 1, 2019; (ii) 2/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2019, but prior to January 1, 2020; and (iii) 3/3, if the Participant’s employment or service terminates with the Employer on or after January 1, 2020. If the Participant ceases to be employed by, or provide service to, the Employer for any reason other than on account of Cause, the prorated number of Performance Units will be distributed in accordance with Paragraph 5.

(b)If at any time prior to the earlier of January 1, 2018 or a Change of Control, the Participant’s employment or service with the Employer is terminated by the Employer on account of any reason or no reason or by the Participant for any reason or no reason, all of the Performance Units subject to this Grant shall be immediately forfeited as of the date of the Participant’s termination of employment or service with the Employer and the Participant shall not have any rights with respect to the distribution of any portion of the Performance Units.

(c)If at any time prior to the date the Performance Units are distributed in accordance with Paragraph 5 the Participant’s employment or service with the Employer is terminated on account of Cause, all of the Performance Units subject to this Grant shall be immediately forfeited and the Participant will not have any rights with respect to the distribution of any portion of the Performance Units, irrespective of the level of achievement of the performance goal. For purposes of this Grant, the term “Cause” shall mean a finding by the Committee that the Participant (i) has breached his or her employment or service contract with the Employer, if any; (ii) has engaged in disloyalty to the Employer, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty; (iii) has disclosed trade secrets or confidential information of the Employer to persons not entitled to receive such information; (iv) has breached any written noncompetition or non-solicitation agreement between the Participant and the Employer; or (v) has engaged in such other behavior detrimental to the interests of the Employer as the Committee determines.

Unless an election is made pursuant to Paragraph 6 below, the Participant will receive a distribution with respect to the Performance Units earned as described in Paragraphs 3 and 4 above within seventy (70) days following the earlier of (a) January 1, 2020 (the “Distribution Date”), or (b) the Change of Control Date.  The Performance Units will be distributed in shares of Company Stock, with each Performance Unit earned equivalent to one share of Company Stock.  Any Performance Units not earned because of the failure to attain the performance goal and service condition will be forfeited.

6.Deferrals. The Participant may make an irrevocable election to defer the Distribution Date (or further defer the Deferred Date (as defined below), if applicable) of all of the Performance Units that are earned, plus dividend equivalents earned on such Performance Units as described in Paragraph 7 below, to a later date, provided that (a) the election shall not take effect until at least twelve (12) months after the date on which the election is made, (b) the deferred Distribution Date cannot be earlier than five (5) years from the original Distribution Date under Paragraph 5 above (or five (5) years from the applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made), and (c) the election must be made no less than twelve (12) months prior to the date of the Distribution Date (twelve (12) months prior to the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made). To defer the Distribution Date, the Participant must elect to defer 100% of the Performance Units, including corresponding dividend equivalents, earned by the Participant under this Grant, as well as 100% of the other performance stock units, including corresponding dividend equivalents, earned by the Participant under the 2017 LTPP, and complete the deferral election form provided to the Participant by the Committee. If the Participant desires to make a further deferral, the Participant must make such election on a separate form provided by the Committee for such purpose. Any such election shall be made in accordance with section 409A of the Code and any corresponding guidance and regulations issued under section 409A of the Code.

4

Paragraph, if the Change of Control Date occurs prior to the Deferred Date, the distribution of the Participant’s earned Performance Units, plus corresponding dividend equivalents, will be the Change of Control Date.

No interest shall accrue on any dividend equivalents credited to the Participant’s Dividend Equivalent Account.

8.Change of Control. Except as set forth above, the provisions set forth in the Plan applicable to a Change of Control (as defined in the Plan) shall apply to the Performance Units, and, in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan and is consistent with the requirements of section 409A of the Code.

10.Restrictions on Issuance or Transfer of Shares of Company Stock.

(a)To the extent permitted by Code section 409A, the obligation of the Company to deliver shares of Company Stock upon the Participant earning the Performance Units shall be subject to the condition that if at any time the Committee shall determine in its discretion that the listing, registration or qualification of the shares of Company Stock upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance of shares of Company Stock, the shares of Company Stock may not be issued in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Committee.

AMERICAN WATER WORKS COMPANY, INC.

2007 OMNIBUS EQUITY COMPENSATION PLAN

PERFORMANCE STOCK UNIT GRANT

This PERFORMANCE STOCK UNIT GRANT, dated as of February 14, 2017, (the “Date of Grant”), is delivered by American Water Works Company, Inc. (the “Company”) to ______________ (the “Participant”).

RECITALS

WHEREAS, the Committee (as defined in the American Water Works Company, Inc. 2007 Omnibus Equity Compensation Plan (the “Plan”)) has adopted a 2017 Long Term Performance Plan (“2017 LTPP”) pursuant to which designated employees will be granted equity awards (collectively, the “Equity Award”) for shares of Common Stock of the Company, par value $0.01 per share, (the “Company Stock”);

WHEREAS, the Equity Award is comprised of three separate grants: a restricted stock unit, and two performance stock unit grants;

WHEREAS, the Committee has determined that the Participant is eligible to participate in the 2017 LTPP and to grant the Participant an Equity Award under the 2017 LTPP; and

WHEREAS, the Committee has determined that the performance stock unit portion of the Equity Award granted to the Participant pursuant to the 2017 LTPP shall be issued under the Plan, and the terms and conditions of the performance stock unit grant that may be earned based on the performance goal relating to the Company’s Total Stockholder Return shall be memorialized in this grant (the “Grant”).

NOW, THEREFORE, the parties to this Grant, intending to be legally bound hereby, agree as follows:

1.Grant of Performance Stock Units. Subject to the terms and conditions set forth in this Grant and the Plan, the Company hereby grants to the Participant _________ performance stock units (the “Performance Units”). The Performance Units are contingently awarded and will be earned and distributable if and only to the extent that the performance goal and other conditions set forth in this Grant are met. Each Performance Unit shall be a phantom right and shall be equivalent to one share of Company Stock on the applicable payment date, as described in Paragraph 5 below. The number of Performance Units set forth above is equal to the target number of shares of Company Stock that the Participant will earn for 100% achievement of the performance goal described in Paragraph 3 below (the “Target Award”).

2.Performance Unit Account. The Company shall establish and maintain a Performance Unit account as a bookkeeping account on its records (the “Performance Unit Account”) for the Participant and shall record in such Performance Unit Account the number of Performance Units granted to the Participant.  The Participant shall not have any interest in any fund or specific assets of the Company by reason of this grant or the Performance Unit Account established for the Participant.

3.Performance Goal.

(a)Unless a Change of Control (as defined below) occurs prior to the end of Performance Period (as defined below), the distribution of the shares of Company Stock attributable to the Performance Units is contingent upon achievement of the performance goal described in subparagraph (b) below for the Performance Period and the Participant satisfying the continuation of employment and service with the Employer (as defined in the Plan) requirement described in Paragraph 4 below.  

(b)The Company’s Total Stockholder Return (“TSR”) (as described in subparagraph (c) below) will be compared to the TSR of the Peer Group companies set forth in Exhibit A attached hereto over the Performance Period (as defined below). The actual number of Performance Units the Participant earns may be greater or less than the Target Award, or even zero, based on the Company’s TSR percentile ranking relative to the TSR performance of the companies in the Peer Group, as follows:

Level of Achievement	Percentile Ranking Relative to Peer Group	Percentage of Target Award Earned
Maximum	90%	200%
Target	50%	100%
Threshold	25%	25%

If the Company’s actual TSR performance is between measuring points, the number of Performance Units the Participant earns will be interpolated. If the Company’s actual TSR performance is below the threshold, no Performance Units will be earned and all of Performance Units will be forfeited. If the Company’s actual TSR performance is greater than the maximum, only the maximum number of Performance Units will be earned.

(c)TSR represents stock price performance and dividend accumulation over the Performance Period for the Company and Peer Group. For purposes of this calculation, the initial stock price and the ending stock price are determined using the twenty (20) day average stock price for December 31, 2016, and December 31, 2019, as applicable. The twenty (20) day average stock price is the average of the daily closing stock prices for the twenty (20) trading days that end on the applicable December 31. If December 31 is not a trading day, the closing stock price on the first trading day prior to December 31 shall be used. To determine stock price performance, each closing stock price shall be adjusted by a dividend adjustment factor. The dividend adjustment factor takes into account each per share dividend paid for the Performance Period as well as the effect of any appreciation in stock price by reason of deeming the dividend to be reinvested in the stock.  Dividend adjusted stock prices shall be obtained from Bloomberg. The dividend adjusted price obtained from Bloomberg provides the closing price for the requested day, week, or month, adjusted for all applicable splits and dividend distributions.  At the end of the Performance Period, the TSR for the Company, and for each company in the Peer Group, shall be determined pursuant to the following formula:

TSR = (Dividend Adjusted Ending Stock Price – Dividend Adjusted Initial Stock Price)

Dividend Adjusted Initial Stock Price

2

The result shall be rounded to the nearest hundredth of one percent (.01%).

(d)As soon as administratively practicable following the end of the Performance Period (as defined in Section 3(f) below), the Committee will determine whether and to what extent the performance goal has been met and certify the number of Performance Units the Participant has earned, if any.  Except as described in Paragraph 4 below, the Participant must be employed by, or providing service to, the Employer on the last day of the Performance Period in order to earn the Performance Units.

(e)If a Change of Control occurs prior to the end of the Performance Period, then the Performance Period will end on the date of the Change of Control and the Performance Units will be deemed earned at the Target Award level as of the date of the Change of Control (the “Change of Control Date”). For purposes of this Grant, the term “Change of Control” shall mean as such term is defined in the Plan, except that a Change of Control shall not be deemed to have occurred for purposes of this Grant unless the event constituting the Change of Control constitutes a change in ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, within the meaning of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and its corresponding regulations.

(f)For purposes of this Grant, the term “Performance Period” shall mean the three (3)-year period beginning on January 1, 2017 and ending December 31, 2019, and the term “Peer Group” shall mean those companies included in Exhibit A as of January 1, 2017.  If at any time during the Performance Period a company in the Peer Group is no longer a publicly traded entity, such company shall be removed from the Peer Group as of January 1 of the year in which the company is no longer publicly traded.

4.Termination of Employment or Service.

(a)If, at least one year after the beginning of the Performance Period, but prior to the end of the Performance Period, the Participant ceases to be employed by, or provide service to, the Employer on account of any reason other than a termination for Cause (as defined below), the Participant will earn a pro-rata portion of the Performance Units, if the performance goal and the requirements of this Grant are met as of the last day of the Performance Period. The pro-rata portion earned will be equal to the number of Performance Units that would have been earned if the Participant had remained employed through the last day of the Performance Period, multiplied by a fraction, which fraction shall be equal to (i) 1/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2018, but prior to January 1, 2019; (ii) 2/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2019, but prior to January 1, 2020; and (iii) 3/3, if the Participant’s employment or service terminates with the Employer on or after January 1, 2020. If the Participant ceases to be employed by, or provide service to, the Employer for any reason other than on account of Cause, the prorated number of Performance Units will be distributed in accordance with Paragraph 5.

(b)Notwithstanding any provision of this Agreement to the contrary, if, at least one year after the beginning of the Performance Period, but prior to the end of the Performance Period, the Participant ceases to be employed by, or provide service to, the Employer on account of Normal Retirement, the Participant will earn the number of Performance Units that would have been earned

3

if the Participant had remained employed through the last day of the Performance Period, if the performance goal and the requirements of this Grant are met as of the last day of the Performance Period.  If the Participant ceases to be employed by, or provide service to, the Employer on account of Normal Retirement pursuant to this subparagraph (b), the number of Performance Units that are earned based on the performance goal and other requirements of this Grant will be distributed in accordance with Paragraph 5.  For purposes of this Grant, “Normal Retirement” shall mean termination of employment or service with the Employer (other than for Cause) after the Participant has attained age sixty-two (62) and five (5) total years of employment or service with the Employer.

(c)If at any time prior to the earlier of January 1, 2018 or a Change of Control, the Participant’s employment or service with the Employer is terminated by the Employer on account of any reason or no reason or by the Participant for any reason or no reason, all of the Performance Units subject to this Grant shall be immediately forfeited as of the date of the Participant’s termination of employment or service with the Employer and the Participant shall not have any rights with respect to the distribution of any portion of the Performance Units.

(d)If at any time prior to the date the Performance Units are distributed in accordance with Paragraph 5 the Participant’s employment or service with the Employer is terminated on account of Cause, all of the Performance Units subject to this Grant shall be immediately forfeited and the Participant will not have any rights with respect to the distribution of any portion of the Performance Units, irrespective of the level of achievement of the performance goal. For purposes of this Grant, the term “Cause” shall mean a finding by the Committee that the Participant (i) has breached his or her employment or service contract with the Employer, if any; (ii) has engaged in disloyalty to the Employer, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty; (iii) has disclosed trade secrets or confidential information of the Employer to persons not entitled to receive such information; (iv) has breached any written noncompetition or non-solicitation agreement between the Participant and the Employer; or (v) has engaged in such other behavior detrimental to the interests of the Employer as the Committee determines.

5.Time and Form of Payment with Respect to Performance Units. Unless an election is made pursuant to Paragraph 6 below, the Participant will receive a distribution with respect to the Performance Units earned as described in Paragraphs 3 and 4 above within seventy (70) days following the earlier of (a) January 1, 2020 (the “Distribution Date”), or (b) the Change of Control Date.  The Performance Units will be distributed in shares of Company Stock, with each Performance Unit earned equivalent to one share of Company Stock.  Any Performance Units not earned because of the failure to attain the performance goal and service condition will be forfeited.

6.Deferrals. The Participant may make an irrevocable election to defer the Distribution Date (or further defer the Deferred Date (as defined below), if applicable) of all of the Performance Units that are earned, plus dividend equivalents earned on such Performance Units as described in Paragraph 7 below, to a later date, provided that (a) the election shall not take effect until at least twelve (12) months after the date on which the election is made, (b) the deferred Distribution Date cannot be earlier than five (5) years from the original Distribution Date under Paragraph 5 above (or five (5) years from the applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made), and (c) the election must be made no less than twelve (12) months prior to the date

4

of the Distribution Date (twelve (12) months prior to the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made). To defer the Distribution Date, the Participant must elect to defer 100% of the Performance Units, including corresponding dividend equivalents, earned by the Participant under this Grant, as well as 100% of the other performance stock units, including corresponding dividend equivalents, earned by the Participant under the 2017 LTPP, and complete the deferral election form provided to the Participant by the Committee. If the Participant desires to make a further deferral, the Participant must make such election on a separate form provided by the Committee for such purpose. Any such election shall be made in accordance with section 409A of the Code and any corresponding guidance and regulations issued under section 409A of the Code. Notwithstanding a Participant’s election pursuant to this Paragraph, if the Change of Control Date occurs prior to the Deferred Date, the distribution of the Participant’s earned Performance Units, plus corresponding dividend equivalents, will be the Change of Control Date. If a Distribution Date is delayed one or more times pursuant to this Paragraph 6, the new Distribution Date shall be referred to as the “Deferred Date.”

7.Dividend Equivalents. Until the earlier of the Distribution Date (or the Deferred Date, if elected) or the Change of Control Date, if any dividends are paid with respect to the shares of Company Stock, the Company shall credit to a dividend equivalent account (the “Dividend Equivalent Account”) the value of the dividends that would have been distributed if the Performance Units credited to the Participant’s Performance Unit Account as of the date of payment of any such dividend were shares of Company Stock.  At the same time that the Performance Units are converted to shares of Company Stock and distributed to the Participant, the Company shall pay to the Participant a lump sum cash payment equal to the value of the dividends credited to the Participant’s Dividend Equivalent Account; provided, however, that any dividends that were credited to the Participant’s Dividend Equivalent Account that are attributable to Performance Units that have been forfeited as provided in Paragraph 3 and 4 above shall be forfeited and not payable to the Participant. No interest shall accrue on any dividend equivalents credited to the Participant’s Dividend Equivalent Account.

8.Change of Control. Except as set forth above, the provisions set forth in the Plan applicable to a Change of Control (as defined in the Plan) shall apply to the Performance Units, and, in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan and is consistent with the requirements of section 409A of the Code.

9.Acknowledgment by Participant. By accepting this Grant, the Participant acknowledges that, with respect to any right to distribution pursuant to the Plan or this Grant, the Participant is and shall be an unsecured general creditor of the Company without any preference as against other unsecured general creditors of the Company, and the Participant hereby covenants for himself or herself, and anyone at any time claiming through or under the Participant, not to claim any such preference, and hereby disclaims and waives any such preference which may at any time be at issue, to the fullest extent permitted by applicable law.

(b)The issuance of shares of Company Stock and the payment of cash to the Participant pursuant to this Grant is subject to any applicable taxes and other laws or regulations of the United States or of any state having jurisdiction thereof.

AMERICAN WATER WORKS COMPANY, INC.

2007 OMNIBUS EQUITY COMPENSATION PLAN

PERFORMANCE STOCK UNIT GRANT

This PERFORMANCE STOCK UNIT GRANT, dated as of February 14, 2017 (the “Date of Grant”), is delivered by American Water Works Company, Inc. (the “Company”) to _____________ (the “Participant”).

RECITALS

WHEREAS, the Committee (as defined in the American Water Works Company, Inc. 2007 Omnibus Equity Compensation Plan (the “Plan”)) has adopted a 2017 Long Term Performance Plan (“2017 LTPP”) pursuant to which designated employees will be granted equity awards (collectively, the “Equity Award”) for shares of Common Stock of the Company, par value $0.01 per share (the “Company Stock”);

WHEREAS, the Equity Award is comprised of three separate grants: a restricted stock unit and two performance stock unit grants;

WHEREAS, the Committee has determined that the Participant is eligible to participate in the 2017 LTPP and to grant the Participant an Equity Award under the 2017 LTPP; and

WHEREAS, the Committee has determined that the performance stock unit portion of the Equity Award granted to the Participant pursuant to the 2017 LTPP shall be issued under the Plan, and the terms and conditions of the performance stock unit grant that may be earned based on performance goals relating to compounded earnings per share, as set forth in Exhibit A attached hereto, shall be memorialized in this grant (the “Grant”).

NOW, THEREFORE, the parties to this Grant, intending to be legally bound hereby, agree as follows:

1. Grant of Performance Stock Units. Subject to the terms and conditions set forth in this Grant and the Plan, the Company hereby grants to the Participant _________ performance stock units (the “Performance Units”). The Performance Units are contingently awarded and will be earned and distributable if and only to the extent that the Performance Goals (as defined below) and other conditions set forth in this Grant are met. Each Performance Unit shall be a phantom right and shall be equivalent to one share of Company Stock on the applicable payment date, as described in Paragraph 5 below. The number of Performance Units set forth above is equal to the target number of shares of Company Stock that the Participant will earn for 100% achievement of the Performance Goals described in this Grant (the “Target Award”).

2. Performance Unit Account. The Company shall establish and maintain a Performance Unit account as a bookkeeping account on its records (the “Performance Unit Account”) for the Participant and shall record in such Performance Unit Account the number of Performance Units granted to the Participant. The Participant shall not have any interest in any fund or specific assets of the Company by reason of this grant or the Performance Unit Account established for the Participant.

3. Performance Goals.

(a)Unless a Change of Control (as defined below) occurs prior to the end of the Performance Period (as defined below), the distribution of the shares of Company Stock attributable to the Performance Units is contingent upon achievement of the performance goals set forth in Exhibit A attached hereto (the “Performance Goals”) and the Participant satisfying the continuation of employment and service with the Employer (as defined in the Plan) requirement described in Paragraph 4 below.

(b)As soon as administratively practicable following the end of the Performance Period (as defined in Section 3(d) below), the Committee will determine whether and to what extent the Performance Goals have been met and certify the number of Performance Units the Participant has earned, if any. Except as described in Paragraph 4 below, the Participant must be employed by, or providing service to, the Employer on the last day of the Performance Period in order to earn the Performance Units.

(c)If a Change of Control occurs prior to the end of the Performance Period, then the Performance Period will end on the date of the Change of Control and the Performance Units will be deemed earned at the Target Award level as of the date of the Change of Control (the “Change of Control Date”). For purposes of this Grant, the term “Change of Control” shall mean as such term is defined in the Plan, except that a Change of Control shall not be deemed to have occurred for purposes of this Grant unless the event constituting the Change of Control constitutes a change in ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, within the meaning of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and its corresponding regulations.

(d)For purposes of this Grant, the term “Performance Period” shall mean the three (3)-year period beginning on January 1, 2017 and ending December 31, 2019.

4. Termination of Employment or Service.

(a)If, at least one year after the beginning of the Performance Period, but prior to the end of the Performance Period, the Participant ceases to be employed by, or provide service to, the Employer on account of any reason other than a termination for Cause (as defined below), the Participant will earn a pro-rata portion of the Performance Units, if the Performance Goals and the requirements of this Grant are met as of the last day of the Performance Period. The pro-rata portion earned will be equal to the number of Performance Units that would have been earned if the Participant had remained employed through the last day of the Performance Period, multiplied by a fraction, which fraction shall be equal to (i) 1/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2018, but prior to January 1, 2019; (ii) 2/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2019, but prior to January 1, 2020; and (iii) 3/3, if the Participant’s employment or service terminates with the Employer on or after January 1, 2020. If the Participant ceases to be employed by, or provide service to, the Employer for any reason other than on account of Cause, the prorated number of Performance Units will be distributed in accordance with Paragraph 5.  

(b)If at any time prior to the earlier of January 1, 2018 or a Change of Control, the

2

Participant’s employment or service with the Employer is terminated by the Employer on account of any reason or no reason or by the Participant for any reason or no reason, all of the Performance Units subject to this Grant shall be immediately forfeited as of the date of the Participant’s termination of employment or service with the Employer and the Participant shall not have any rights with respect to the distribution of any portion of the Performance Units.

(c)If at any time prior to the date the Performance Units are distributed in accordance with Paragraph 5 the Participant’s employment or service with the Employer is terminated on account of Cause, all of the Performance Units subject to this Grant shall be immediately forfeited and the Participant will not have any rights with respect to the distribution of any portion of the Performance Units, irrespective of the level of achievement of the Performance Goals. For purposes of this Grant, the term “Cause” shall mean a finding by the Committee that the Participant (i) has breached his or her employment or service contract with the Employer, if any; (ii) has engaged in disloyalty to the Employer, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty; (iii) has disclosed trade secrets or confidential information of the Employer to persons not entitled to receive such information; (iv) has breached any written noncompetition or non-solicitation agreement between the Participant and the Employer; or (v) has engaged in such other behavior detrimental to the interests of the Employer as the Committee determines.

5. Time and Form of Payment with Respect to Performance Units. Unless an election is made pursuant to Paragraph 6 below, the Participant will receive a distribution with respect to the Performance Units earned as described in Paragraphs 3 and 4 above within seventy (70) days following the earlier of (a) January 1, 2020 (the “Distribution Date”), or (b) the Change of Control Date. The Performance Units will be distributed in shares of Company Stock, with each Performance Unit earned equivalent to one share of Company Stock. Any Performance Units not earned because of the failure to attain the Performance Goals and service condition will be forfeited.

6. Deferrals. The Participant may make an irrevocable election to defer the Distribution Date (or further defer the Deferred Date (as defined below), if applicable) of all of the Performance Units that are earned, plus dividend equivalents earned on such Performance Units as described in Paragraph 7 below, to a later date, provided that (a) the election shall not take effect until at least twelve (12) months after the date on which the election is made, (b) the deferred Distribution Date cannot be earlier than five (5) years from the original Distribution Date under Paragraph 5 above (or five (5) years from the applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made), and (c) the election must be made no less than twelve (12) months prior to the date of the Distribution Date (twelve (12) months prior to the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made). To defer the Distribution Date, the Participant must elect to defer 100% of the Performance Units, including corresponding dividend equivalents, earned by the Participant under this Grant, as well as 100% of the other performance stock units, including corresponding dividend equivalents, earned by the Participant under the 2017 LTPP, and complete the deferral election form provided to the Participant by the Committee. If the Participant desires to make a further deferral, the Participant must make such election on a separate form provided by the Committee for such purpose. Any such election shall be made in accordance with section 409A of the Code and any corresponding guidance and regulations issued under section 409A of the Code. Notwithstanding a Participant’s election pursuant to this

3

Paragraph, if the Change of Control Date occurs prior to the Deferred Date, the distribution of the Participant’s earned Performance Units, plus corresponding dividend,equivalents will be the Change of Control Date. If a Distribution Date is delayed one or more times pursuant to this Paragraph 6, the new Distribution Date shall be referred to as the “Deferred Date.”

7. Dividend Equivalents. Until the earlier of the Distribution Date (or the Deferred Date, if elected) or the Change of Control Date, if any dividends are paid with respect to the shares of Company Stock, the Company shall credit to a dividend equivalent account (the “Dividend Equivalent Account”) the value of the dividends that would have been distributed if the Performance Units credited to the Participant’s Performance Unit Account as of the date of payment of any such dividend were shares of Company Stock. At the same time that the Performance Units are converted to shares of Company Stock and distributed to the Participant, the Company shall pay to the Participant a lump sum cash payment equal to the value of the dividends credited to the Participant’s Dividend Equivalent Account; provided, however, that any dividends that were credited to the Participant’s Dividend Equivalent Account that are attributable to Performance Units that have been forfeited as provided in Paragraph 3 and 4 above shall be forfeited and not payable to the Participant. No interest shall accrue on any dividend equivalents credited to the Participant’s Dividend Equivalent Account.

8. Change of Control. Except as set forth above, the provisions set forth in the Plan applicable to a Change of Control (as defined in the Plan) shall apply to the Performance Units, and, in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan and is consistent with the requirements of section 409A of the Code.

10. Restrictions on Issuance or Transfer of Shares of Company Stock.

(a)To the extent permitted by Code section 409A, the obligation of the Company to deliver shares of Company Stock upon the Participant earning the Performance Units shall be subject to the condition that if at any time the Committee shall determine in its discretion that the listing, registration or qualification of the shares of Company Stock upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance of shares of Company Stock, the shares of Company Stock may not be issued in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Committee.

(b)The issuance of shares of Company Stock and the payment of cash to the Participant pursuant to this Grant is subject to any applicable taxes and other laws or regulations of the United States or of any state having jurisdiction thereof.

“PSU GRANT B – EPS”

EXHIBIT A

PERFORMANCE GOAL

To satisfy the provisions under 162m, a “plan within a plan” approach, using a threshold goal of positive net income, on a GAAP basis over the period 1/1/2017 to 12/31/2019, to fund the payout pool.  

Once threshold performance has been achieved, the LTPP pool funds up to the 200% maximum allowed per participant under the “inside” plan, as outlined below.  Negative discretion may be applied by the Committee based on the performance of the “inside” plan criteria

The number of Performance Units that may be earned shall be determined based on the  achievement of Compounded Earnings Per Share Growth (as described below) over the Performance Period.

Compounded Earnings Per Share (“EPS”) Growth – will be calculated based on fully diluted EPS calculated in accordance with US GAAP as reported in the Company’s audited consolidated financial statements adjusted to exclude all items of gain, loss or expense for the fiscal year determined to be extraordinary or unusual in nature or infrequent in occurrence or related to the disposal of a segment of a business or related to a change in accounting principle. The starting point for the calculation will be adjusted EPS of $2.84 for the year ended December 31, 2016. The ending point for the calculation will be EPS for the year ended December 31, 2019, adjusted to exclude all items of gain, loss or expense for the fiscal year determined to be extraordinary or unusual in nature or infrequent in occurrence or related to the disposal of a segment of a business or related to a change in accounting principle.

As soon as administratively practicable following the end of the Performance Period, the Committee will certify the level of achievement of the Compounded EPS Growth.

9

The award scale for Compounded EPS Growth is as follows:

Compounded EPS Growth
Actual Compounded Growth	Target Award
12.0% or more		200%
10.0%		175%
7.8%		100%
6.0%		25%
<= 5.99%		0%

If actual achievement of the Performance Goal do not meet threshold performance (i.e., less than 6.0% for Compounded EPS Growth, then that Performance Goal will be reflected in the final result for determining the number of earned Performance Units at its assigned weighting with a 0%. The maximum award that may be earned for each Performance Goal is capped at 200%, and the maximum award that may be earned by the Participant is capped at 200% of the Target Award.

Example:

The following is an example calculation for a Participant with a Target Award of 1,000 Performance Units:

Earnings Per Share

	12/31/2016		12/31/2019
	Adjusted		Illustration
Adjusted diluted earnings per share from continuing operations	$	2.84	$	3.06
Compounded annual growth rate				8.06%

10

Earned Performance Units

	Achievement		Award		Weighting		Weighted Payout
Compounded Earnings Per Share Growth		8.06%		109.4%		100%		109.4%

In this example, the individual who was awarded a Target Grant of 1,000 Performance Units would earn 1,094 Performance Units (1,000 x 1.094), which is convertible into an equivalent number of shares of Company Stock assuming all other terms and conditions of the Grant have been satisfied.

NOW, THEREFORE, the parties to this Grant, intending to be legally bound hereby, agree as follows:

1.Grant of Performance Stock Units. Subject to the terms and conditions set forth in this Grant and the Plan, the Company hereby grants to the Participant ____________ performance stock units (the “Performance Units”). The Performance Units are contingently awarded and will be earned and distributable if and only to the extent that the Performance Goals (as defined below) and other conditions set forth in this Grant are met. Each Performance Unit shall be a phantom right and shall be equivalent to one share of Company Stock on the applicable payment date, as described in Paragraph 5 below. The number of Performance Units set forth above is equal to the target number of shares of Company Stock that the Participant will earn for 100% achievement of the Performance Goals described in this Grant (the “Target Award”).

2.Performance Unit Account. The Company shall establish and maintain a Performance Unit account as a bookkeeping account on its records (the “Performance Unit Account”) for the Participant and shall record in such Performance Unit Account the number of Performance Units granted to the Participant. The Participant shall not have any interest in any fund or specific assets of the Company by reason of this grant or the Performance Unit Account established for the Participant.

3.Performance Goals.

(a)Unless a Change of Control (as defined below) occurs prior to the end of the Performance Period (as defined below), the distribution of the shares of Company Stock attributable to the Performance Units is contingent upon achievement of the performance goals set forth in Exhibit A attached hereto (the “Performance Goals”) and the Participant satisfying the continuation of employment and service with the Employer (as defined in the Plan) requirement described in Paragraph 4 below.

(b)As soon as administratively practicable following the end of the Performance Period (as defined in Section 3(d) below), the Committee will determine whether and to what extent the Performance Goals have been met and certify the number of Performance Units the Participant has earned, if any. Except as described in Paragraph 4 below, the Participant must be employed by, or providing service to, the Employer on the last day of the Performance Period in order to earn the Performance Units.

(c)If a Change of Control occurs prior to the end of the Performance Period, then the Performance Period will end on the date of the Change of Control and the Performance Units will be deemed earned at the Target Award level as of the date of the Change of Control (the “Change of Control Date”). For purposes of this Grant, the term “Change of Control” shall mean as such term is defined in the Plan, except that a Change of Control shall not be deemed to have occurred for purposes of this Grant unless the event constituting the Change of Control constitutes a change in ownership or effective control of the Company, or in the ownership of a substantial portion of the assets of the Company, within the meaning of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and its corresponding regulations.

(d)For purposes of this Grant, the term “Performance Period” shall mean the three (3)-year period beginning on January 1, 2017 and ending December 31, 2019.

4.Termination of Employment or Service.

(a)If, at least one year after the beginning of the Performance Period, but prior to the end of the Performance Period, the Participant ceases to be employed by, or provide service to, the Employer on account of any reason other than a termination for Cause (as defined below), the Participant will earn a pro-rata portion of the Performance Units, if the Performance Goals and the requirements of this Grant are met as of the last day of the Performance Period. The pro-rata portion earned will be equal to the number of Performance Units that would have been earned if the Participant had remained employed through the last day of the Performance Period, multiplied by a fraction, which fraction shall be equal to (i) 1/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2018, but prior to January 1, 2019; (ii) 2/3, if the Participant’s employment or service with the Employer terminates on or after January 1, 2019, but prior to January 1, 2020; and (iii) 3/3, if the Participant’s employment or service terminates with the Employer on or after January 1, 2020. If the Participant ceases to be employed by, or provide service to, the Employer for any reason other than on account of Cause, the prorated number of Performance Units will be distributed in accordance with Paragraph 5.  

2

(b)Notwithstanding any provision of this Agreement to the contrary, if, at least one year after the beginning of the Performance Period, but prior to the end of the Performance Period, the Participant ceases to be employed by, or provide service to, the Employer on account of Normal Retirement, the Participant will earn the number of Performance Units that would have been earned if the Participant had remained employed through the last day of the Performance Period, if the Performance Goals and the requirements of this Grant are met as of the last day of the Performance Period.  If the Participant ceases to be employed by, or provide service to, the Employer on account of Normal Retirement pursuant to this subparagraph (b), the number of Performance Units that are earned based on the Performance Goals and other requirements of this Grant will be distributed in accordance with Paragraph 5.  For purposes of this Grant, “Normal Retirement” shall mean termination of employment or service with the Employer (other than for Cause) after the Participant has attained age sixty-two (62) and five (5) total years of employment or service with the Employer.

(c)If at any time prior to the earlier of January 1, 2018 or a Change of Control, the Participant’s employment or service with the Employer is terminated by the Employer on account of any reason or no reason or by the Participant for any reason or no reason, all of the Performance Units subject to this Grant shall be immediately forfeited as of the date of the Participant’s termination of employment or service with the Employer and the Participant shall not have any rights with respect to the distribution of any portion of the Performance Units.

(d)If at any time prior to the date the Performance Units are distributed in accordance with Paragraph 5 the Participant’s employment or service with the Employer is terminated on account of Cause, all of the Performance Units subject to this Grant shall be immediately forfeited and the Participant will not have any rights with respect to the distribution of any portion of the Performance Units, irrespective of the level of achievement of the Performance Goals. For purposes of this Grant, the term “Cause” shall mean a finding by the Committee that the Participant (i) has breached his or her employment or service contract with the Employer, if any; (ii) has engaged in disloyalty to the Employer, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty; (iii) has disclosed trade secrets or confidential information of the Employer to persons not entitled to receive such information; (iv) has breached any written noncompetition or non-solicitation agreement between the Participant and the Employer; or (v) has engaged in such other behavior detrimental to the interests of the Employer as the Committee determines.

5.Time and Form of Payment with Respect to Performance Units. Unless an election is made pursuant to Paragraph 6 below, the Participant will receive a distribution with respect to the Performance Units earned as described in Paragraphs 3 and 4 above within seventy (70) days following the earlier of (a) January 1, 2020 (the “Distribution Date”), or (b) the Change of Control Date. The Performance Units will be distributed in shares of Company Stock, with each Performance Unit earned equivalent to one share of Company Stock. Any Performance Units not earned because of the failure to attain the Performance Goals and service condition will be forfeited.

6.Deferrals. The Participant may make an irrevocable election to defer the Distribution Date (or further defer the Deferred Date (as defined below), if applicable) of all of the Performance Units that are earned, plus dividend equivalents earned on such Performance Units as described in

3

Paragraph 7 below, to a later date, provided that (a) the election shall not take effect until at least twelve (12) months after the date on which the election is made, (b) the deferred Distribution Date cannot be earlier than five (5) years from the original Distribution Date under Paragraph 5 above (or five (5) years from the applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made), and (c) the election must be made no less than twelve (12) months prior to the date of the Distribution Date (twelve (12) months prior to the previously applicable Deferred Date, if a subsequent deferral of a Deferred Date is being made). To defer the Distribution Date, the Participant must elect to defer 100% of the Performance Units, including corresponding dividend equivalents, earned by the Participant under this Grant, as well as 100% of the other performance stock units, including corresponding dividend equivalents, earned by the Participant under the 2017LTPP, and complete the deferral election form provided to the Participant by the Committee. If the Participant desires to make a further deferral, the Participant must make such election on a separate form provided by the Committee for such purpose. Any such election shall be made in accordance with section 409A of the Code and any corresponding guidance and regulations issued under section 409A of the Code. Notwithstanding a Participant’s election pursuant to this Paragraph, if the Change of Control Date occurs prior to the Deferred Date, the distribution of the Participant’s earned Performance Units, plus corresponding dividend equivalents, will be the Change of Control Date. If a Distribution Date is delayed one or more times pursuant to this Paragraph 6, the new Distribution Date shall be referred to as the “Deferred Date.”

7.Dividend Equivalents. Until the earlier of the Distribution Date (or the Deferred Date, if elected) or the Change of Control Date, if any dividends are paid with respect to the shares of Company Stock, the Company shall credit to a dividend equivalent account (the “Dividend Equivalent Account”) the value of the dividends that would have been distributed if the Performance Units credited to the Participant’s Performance Unit Account as of the date of payment of any such dividend were shares of Company Stock. At the same time that the Performance Units are converted to shares of Company Stock and distributed to the Participant, the Company shall pay to the Participant a lump sum cash payment equal to the value of the dividends credited to the Participant’s Dividend Equivalent Account; provided, however, that any dividends that were credited to the Participant’s Dividend Equivalent Account that are attributable to Performance Units that have been forfeited as provided in Paragraph 3 and 4 above shall be forfeited and not payable to the Participant. No interest shall accrue on any dividend equivalents credited to the Participant’s Dividend Equivalent Account.

8.Change of Control. Except as set forth above, the provisions set forth in the Plan applicable to a Change of Control (as defined in the Plan) shall apply to the Performance Units, and, in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan and is consistent with the requirements of section 409A of the Code.

9.Acknowledgment by Participant. By accepting this Grant, the Participant acknowledges that, with respect to any right to distribution pursuant to the Plan or this Grant, the Participant is and shall be an unsecured general creditor of the Company without any preference as against other unsecured general creditors of the Company, and the Participant hereby covenants for himself or herself, and anyone at any time claiming through or under the Participant, not to claim any such preference, and hereby disclaims and waives any such preference which may at any time be at issue, to the fullest extent permitted by applicable law.

4

10.Restrictions on Issuance or Transfer of Shares of Company Stock.

(a)To the extent permitted by Code section 409A, the obligation of the Company to deliver shares of Company Stock upon the Participant earning the Performance Units shall be subject to the condition that if at any time the Committee shall determine in its discretion that the listing, registration or qualification of the shares of Company Stock upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance of shares of Company Stock, the shares of Company Stock may not be issued in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Committee.

(b)The issuance of shares of Company Stock and the payment of cash to the Participant pursuant to this Grant is subject to any applicable taxes and other laws or regulations of the United States or of any state having jurisdiction thereof.

(c)As a condition to receive any shares of Company Stock upon conversion of the earned Performance Units, the Participant agrees:

(i)to be bound by, and to comply with, the Company’s policies and practices (as they may be in effect from time to time) regarding the restrictions or limitations on the transfer of such shares, and understands that the Participant may be restricted or prohibited at any time and/or from time to time from selling, transferring, pledging, donating, assigning, margining, mortgaging, hypothecating or otherwise encumbering the shares in accordance with such policies and practices, including without limitation the Company’s Personal Securities and Insider Trading Policy; and

(ii)that any shares of Company Stock received by the Participant upon the distribution of the earned Performance Units pursuant to this Grant shall be subject to the restrictions set forth in the Company’s Executive Stock Ownership Guidelines and Executive Stock Retention Requirements, effective as of March 4, 2015 (and as they may be amended, restated, supplemented and interpreted) and any applicable clawback or recoupment policies and other policies that may be implemented by the Company’s Board of Directors or a duly authorized committee thereof, from time to time.

11.Participant Undertaking.  The Participant agrees to take whatever additional actions and execute whatever additional documents the Company may in its reasonable judgment deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on the Participant pursuant to the provisions of this Grant.

12.Grant Subject to Plan Provisions.

13.No Rights as Stockholder. The Participant shall not have any rights as a stockholder of the Company, including the right to any cash dividends (except as provided in Paragraph 7), or the right to vote, with respect to any Performance Units.

14.No Rights to Continued Employment or Service. This Grant shall not confer upon the Participant any right to be retained in the employment or service of the Employer and shall not interfere in any way with the right of the Employer to terminate the Participant’s employment or service at any time. The right of the Employer to terminate at will the Participant’s employment or service at any time for any reason is specifically reserved.

15.Assignment and Transfers. No Performance Units or dividend equivalents awarded to the Participant under this Grant may be transferred, assigned, pledged, or encumbered by the Participant and the Performance Units and dividend equivalents shall be distributed during the lifetime of the Participant only for the benefit of the Participant.

17.Effect on Other Benefits. The value of shares of Company Stock and dividend equivalents distributed with respect to the Performance Units shall not be considered eligible earnings for purposes of any other plans maintained by the Company or the Employer. Neither shall such value be considered part of the Participant’s compensation for purposes of determining or calculating other benefits that are based on compensation, such as life insurance.

6

18.Applicable Law. The validity, construction, interpretation and effect of this Grant shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the conflicts of laws provisions thereof.

20.Taxation; Code Section 409A. As applicable, this Grant is intended to comply with the requirements of section 409A of the Code and shall be interpreted and administered in accordance with Code section 409A.  Notwithstanding any provision to the contrary herein, if the Performance Units constitute “deferred compensation” under section 409A of the Code, distributions made with respect to this Grant may only be made in a manner and upon an event permitted by Code section 409A.  To the extent that any provision of the Grant would cause a conflict with the requirements of Code section 409A, or would cause the administration of the Grant to fail to satisfy the requirements of Code section 409A, such provision shall, to the extent practicable if permitted by applicable law, be deemed null and void.  In the event that it is determined not feasible to void a provision of this Grant, such provision shall be construed in a manner as to comply with the Code section 409A requirements.

21.Severability.  In the event one or more of the provisions of this Grant should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability will not affect any other provisions of this Grant, and this Grant will be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

“PSU GRANT B – EPS”

EXHIBIT A

PERFORMANCE GOAL

To satisfy the provisions under 162m, a “plan within a plan” approach, using a threshold goal of positive net income, on a GAAP basis over the period 1/1/2017 to 12/31/2019, to fund the payout pool.  

Once threshold performance has been achieved, the LTPP pool funds up to the 200% maximum allowed per participant under the “inside” plan, as outlined below.  Negative discretion may be applied by the Committee based on the performance of the “inside” plan criteria

The number of Performance Units that may be earned shall be determined based on the  achievement of Compounded Earnings Per Share Growth (as described below) over the Performance Period.

Compounded Earnings Per Share (“EPS”) Growth – will be calculated based on fully diluted EPS calculated in accordance with US GAAP as reported in the Company’s audited consolidated financial statements adjusted to exclude all items of gain, loss or expense for the fiscal year determined to be extraordinary or unusual in nature or infrequent in occurrence or related to the disposal of a segment of a business or related to a change in accounting principle. The starting point for the calculation will be adjusted EPS of $2.84 for the year ended December 31, 2016. The ending point for the calculation will be EPS for the year ended December 31, 2019, adjusted to exclude all items of gain, loss or expense for the fiscal year determined to be extraordinary or unusual in nature or infrequent in occurrence or related to the disposal of a segment of a business or related to a change in accounting principle.

As soon as administratively practicable following the end of the Performance Period, the Committee will certify the level of achievement of the Compounded EPS Growth.

The award scale for Compounded EPS Growth is as follows:

Compounded EPS Growth
Actual Compounded Growth	Target Award
12.0% or more		200%
10.0%		175%
7.8%		100%
6.0%		25%
<= 5.99%		0%

9

If actual achievement of the Performance Goal do not meet threshold performance (i.e., less than 6.0% for Compounded EPS Growth, then that Performance Goal will be reflected in the final result for determining the number of earned Performance Units at its assigned weighting with a 0%. The maximum award that may be earned for each Performance Goal is capped at 200%, and the maximum award that may be earned by the Participant is capped at 200% of the Target Award.

Example:

The following is an example calculation for a Participant with a Target Award of 1,000 Performance Units:

Earnings Per Share

	12/31/2016		12/31/2019
	Adjusted		Illustration
Adjusted diluted earnings per share from continuing operations	$	2.84	$	3.06
Compounded annual growth rate				8.06%

Earned Performance Units

	Achievement		Award		Weighting		Weighted Payout
Compounded Earnings Per Share Growth		8.06%		109.4%		100%		109.4%

In this example, the individual who was awarded a Target Grant of 1,000 Performance Units would earn 1,094 Performance Units (1,000 x 1.094), which is convertible into an equivalent number of shares of Company Stock assuming all other terms and conditions of the Grant have been satisfied.

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 March 31, 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 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	Effecton 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 $13 for the three months ended March 31, 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 March 31, 2017:

Standard	Description	Date of Adoption	Application	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 related cash flows.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company is evaluating the impact on the consolidated financial statements and related disclosures, as well as the transition method to be used to adopt the guidance. The Company is also considering the impacts of the new standard on its accounting for contributions in aid of construction. The Company does not expect to early adopt.
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 Company is evaluating the impact on the consolidated financial statements and related disclosures.
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 the 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 the 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 the consolidated financial statements, related disclosures, as well as the timing of adoption.
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 evaluating the impact on the consolidated financial statements and related disclosures, as well as the timing of adoption.
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 the 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 7— 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 three months ended March 31, 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.

Long-Term Debt

Note 5: Long-Term Debt

The following long-term debt was retired through sinking fund provisions, optional redemptions or payment at maturity during the three months ended March 31, 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		2
Other American Water subsidiaries	Mandatorily redeemable preferred stock		8.49%	2036		1
Total retirements and redemptions					$	4

(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 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 a 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 these forward 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 the 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 recognized by the Company was de minimis for the three months ended March 31, 2017 and 2016.

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 instruments as economic hedges accounted for at fair value with gains or losses recognized in interest, net. The net gain recognized by the Company was de minimis for the three months ended March 31, 2017 and 2016.

No ineffectiveness was recognized for the three months ended March 31, 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 6: Income Taxes

The Company’s effective income tax rate was35.9%and39.7%for thethree months ended March 31, 2017 and 2016, respectively. The effective income tax rate for the three months ended March 31, 2017 was impacted by a $5 tax benefitfrom the new accounting standard for employee share-based payment awards which was adopted in 2017. Under this updated guidance, tax benefits or shortfalls related to employee share-based payment awards are recognized in the provision for income taxes, whereas they previously were recorded as additional paid-in capital on the Consolidated Balance Sheets. 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 would increase the state income tax rate on the Company’s taxable income attributable to New York. Manufacturers in New York are taxed at a lower income tax rate, and this legislation eliminated the production of water as a qualified manufacturing activity. The effective date of the legislation is January 1, 2018 and this future increase in the New York tax rate will cause the Company to book a one-time adjustment during the second quarter of 2017, increasing its state accumulated deferred income tax liability.  An offsetting adjustment will be recorded to regulatory assets for the amount recoverable in future customer rates, with the remaining balance recorded to income tax expense.

The Company is routinely involved in legal actions incident to the normal conduct of its business. As of March 31, 2017, the Company has accrued approximately $138 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 8, 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 until June 6, 2017 and remains subject to further delay in light of the binding global agreement in principle described below. The Mass Litigation Panel has also stayed its proceedings until July 26, 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 March 31, 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. 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.

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.

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. 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 March 31, 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 this Note 8.

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 March 29, 2017, the Missouri Office of Public Counsel filed a Motion for Rehearing with the Missouri Supreme Court, which remains pending.

As a result of the Missouri Supreme Court’s decision, the Company has determined that, as of March 31, 2017, a loss associated with this matter is remote.

Fair Value Disclosures [Abstract]

Fair Value of Financial Assets and Liabilities

Note 10: 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 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 March 31, 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)		6,316		3,972		1,363		1,822		7,157
	Carrying		At Fair Value as of December 31, 2016
	Amount		Level 1		Level 2		Level 3		Total

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 $4 were included in other long-term assets as of March 31, 2017 and December 31, 2016.

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.

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.

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.

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	Effecton 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 $13 for the three months ended March 31, 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 March 31, 2017:

Standard	Description	Date of Adoption	Application	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 related cash flows.	January 1, 2018; early adoption permitted	Full or modified retrospective	The Company is evaluating the impact on the consolidated financial statements and related disclosures, as well as the transition method to be used to adopt the guidance. The Company is also considering the impacts of the new standard on its accounting for contributions in aid of construction. The Company does not expect to early adopt.
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 Company is evaluating the impact on the consolidated financial statements and related disclosures.
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 the 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 the 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 the consolidated financial statements, related disclosures, as well as the timing of adoption.
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 evaluating the impact on the consolidated financial statements and related disclosures, as well as the timing of adoption.
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 the consolidated financial statements and related disclosures, as well as the timing of adoption.
