Dear American Water Stockholder:

I am pleased to invite you to attend American Water’s 2013 Annual Meeting of Stockholders on Monday, May 13, 2013. The meeting will be held at 10:00 a.m., Eastern Daylight Time, at The Mansion, 3000 Main Street, Voorhees, New Jersey 08043. For your convenience, we are providing a live webcast (audio only) of the meeting at www.amwater.com. Instructions on accessing the webcast are explained in detail on page 2.

The materials accompanying this letter include a formal notice of the meeting and the proxy statement. The proxy statement provides information on, among other things, American Water’s corporate governance, the Company’s executive compensation program, and the matters to be voted on at the meeting. We believe that matters addressed in the proxy statement reflect American Water’s commitment to strong governance processes, including independent and active board oversight, accountability to stockholders, transparent disclosure and compliance with regulatory responsibilities.

The American Water board of directors’ commitment to sound corporate governance is illustrated by a number of practices adopted in recent years:

• Our Chairman of the Board is an independent director;

• We have instituted a majority vote standard for election of directors;

• We have a policy mandating independence for the Compensation Committee’s compensation consultant;

• We have an annual advisory vote to approve our executive compensation; and

• Stockholders have direct and confidential access to the board of directors through our email address: contacttheboard@amwater.com.

We believe that these steps, and other effective governance practices described in this proxy statement, as well as American Water’s largely performance-based executive compensation program, exhibit our proactive approach to governance. We encourage you to learn more about our governance practices by reading the proxy statement and visiting the Investor Relations page on our website at www.amwater.com.

It is important that your shares be represented and voted at the Annual Meeting regardless of the size of your holdings. Whether or not you plan to attend the Annual Meeting, we encourage you to vote your shares in advance of the Annual Meeting by using one of the methods described in the accompanying proxy materials.

We will set aside time at the meeting for discussion of each item of business, and American Water’s management will report on the Company’s performance during the last fiscal year and respond to questions from stockholders. If you will need special assistance at the meeting because of a disability, please contact Kellye L. Walker, Chief Administrative Officer, General Counsel and Secretary, American Water Works Company, Inc., 1025 Laurel Oak Road, Voorhees, New Jersey 08043, or Investor Relations via email at aw.investorrelations@amwater.com or by telephone at 877-310-7174.

Sincerely,

George MacKenzie

PROXY STATEMENT

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

Our board of directors is soliciting your proxy to vote at our 2013 Annual Meeting of Stockholders (or any adjournment or postponement of the Annual Meeting). This proxy statement contains important information for you to consider when deciding how to vote on the matters brought before the Annual Meeting. Please read it carefully.

In accordance with rules of the Securities and Exchange Commission, which we refer to as the SEC, we are providing to most of our stockholders a Notice of Internet Availability of Proxy Materials, which we refer to as the “Notice,” rather than mailing a printed copy of our proxy materials. Our proxy materials consist of this proxy statement, a proxy card and our annual report to stockholders, which includes our Form 10-K for the year ended December 31, 2012, and a letter from our President and CEO. We are making these materials available to our stockholders beginning on or about March 28, 2013. More information is provided in the following set of questions and answers, including information on how to receive by mail, free of charge, paper copies of the proxy materials.

When and where will the Annual Meeting be held?

The date, time and place of our 2013 Annual Meeting of Stockholders are set forth below:

DATE:	Monday, May 13, 2013
TIME:	10:00 a.m. (Eastern Daylight Time)
PLACE:	The Mansion 3000 Main Street Voorhees, New Jersey 08043

What is the purpose of the Annual Meeting?

At the Annual Meeting, stockholders will consider and take action upon the matters outlined in the Notice of Meeting:

• election to the board of directors of the nine nominees named in this proxy statement to serve until the next annual meeting of stockholders or until their successors are elected and qualified;

• ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2013;

• an advisory vote to approve our executive compensation; and

• such other business, if any, as may properly come before the meeting and any adjournment or postponement of the meeting.

American Water’s management will also report on the Company’s performance during the last fiscal year and respond to questions from stockholders.

1

Who is entitled to vote at the Annual Meeting?

Stockholders of record who owned American Water common stock at the close of business on March 18, 2013, the record date, are entitled to vote. As of the record date, there were 177,616,279 shares of American Water common stock outstanding.

What is required to attend the Annual Meeting?

You will need an admission card and picture identification to enter the Annual Meeting. To obtain an admission card, which will be mailed to you prior to the meeting, please follow the advance registration instructions on the back inside cover of this proxy statement. If your shares are not registered in your own name, you must provide, at the entrance to the Annual Meeting, evidence of your stock ownership as of March 18, 2013. You can obtain this evidence from your bank or brokerage firm, typically in the form of your most recent monthly statement.

To attend the Annual Meeting on the Internet, visit www.virtualshareholdermeeting.com/awk2013. To enter the meeting and vote, you must use your 12-digit Control Number printed on your proxy voting card. Stockholders of record will be able to vote their shares electronically and submit questions during the meeting. Questions submitted online, but not answered during the meeting, will be addressed within the next business day following the meeting.

If you have a disability, we can provide reasonable assistance to help you participate in the meeting. If you plan to attend the meeting and require assistance, please contact Kellye L. Walker, Chief Administrative Officer, General Counsel and Secretary, American Water Works Company, Inc., 1025 Laurel Oak Road, Voorhees, New Jersey, 08043, or Investor Relations by email at aw.investorrelations@amwater.com or by telephone at 877-310-7174, at least one week prior to our meeting.

Will there be a public webcast of the Annual Meeting?

Yes. The Annual Meeting will be webcast live to the public via the Internet on Monday, May 13, 2013, beginning at 10:00 a.m., Eastern Daylight Time. Accessing the webcast will enable you to hear the speakers on a live basis.

The webcast may be accessed on our website at www.amwater.com. Click on “Investors Relations” at the top of the page, and follow the Annual Meeting webcast link under Upcoming Events. Minimum requirements to listen to this broadcast online are: Windows Media Player software, downloadable at www.microsoft.com/windows/windowsmedia/download/default.asp, and at least a 28K connection to the Internet.

To listen to the live webcast, please go to the website at least 30 minutes early to download and install any necessary software. If you plan to listen online, we suggest that you test your computer’s access to Windows Media Player by visiting the above URL one week prior to the meeting date.

What are the board of directors’ recommendations regarding the matters to be acted on at the Annual Meeting?

The board of directors recommends a vote:

• FOR the election of all director nominees named in this proxy statement;

• FOR the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2013; and

• FOR the approval, on an advisory basis, of our executive compensation.

2

What is e-proxy, and why is American Water using it?

E-proxy is the informal name for a process permitted by SEC rules. Under this process, a company can make its proxy materials available to some or all of its stockholders over the Internet, instead of mailing paper copies of the proxy materials to every stockholder. We are using e-proxy to distribute proxy materials to some of our stockholders because it will reduce our printing and mailing costs and reduce the consumption of paper and other resources.

How do I access the proxy materials on the Internet?

We have mailed to some of our stockholders a Notice. If you hold your shares through a bank or broker, that bank or broker will arrange to have a Notice provided to you. The Notice has instructions on how to access our proxy materials on the Internet.

I received the Notice, but I prefer to read my proxy materials on paper—can I get paper copies?

Yes. The Notice has instructions on how to request paper copies by telephone, e-mail or on the Internet. We will send, free of charge, printed materials by first class mail within three business days of receiving your request, either directly or through your bank or broker. If you so indicate in your request, you also will receive the materials in paper form with respect to future stockholder meetings.

I previously consented to the electronic delivery of proxy materials—will I continue to receive them via e-mail?

Yes. If you have already elected to receive proxy materials electronically, you will continue to receive them that way.

How many votes do I have?

Each outstanding share of American Water common stock is entitled to one vote. The number of shares you own is reflected on your proxy card.

Is there a difference between holding shares “of record” and holding shares in “street name”?

Yes. If your shares are registered directly in your name, you are considered to be the stockholder “of record” with respect to those shares, and either the Notice or paper copies of the proxy materials are being sent directly to you by American Water. If your shares are held in the name of a bank or broker, then you are considered to hold those shares in “street name.” In that case, the Notice is being sent to you or paper copies of the proxy materials are being forwarded to you by or on behalf of your bank or broker.

How many votes must be present to hold the Annual Meeting?

A quorum of shares outstanding is necessary to hold a valid meeting. The presence at the meeting, in person or by proxy, of the holders of record of a majority of the shares entitled to vote constitutes a quorum.

How can I vote my shares?

If you are a holder of record, you may vote in person at the Annual Meeting or you may designate another person—your proxy—to vote your stock. The written document used to designate someone as your proxy also is called a proxy or proxy card. We urge you to vote your shares by proxy even if you plan to attend the Annual Meeting. You can change your vote at the meeting. If you are a stockholder of record, you can vote by proxy over the Internet or by telephone by following the instructions in the Notice, or, if you received printed copies of the proxy materials by mail, you can also vote by submitting your proxy by mail or telephone.

3

If your shares are held in “street name,” then you may give voting instructions in the manner provided by your bank or broker. Please note that New York Stock Exchange rules prohibit your broker from voting on the election of directors and the advisory vote on executive compensation. Without your voting instructions to your bank or broker, your shares will not be represented.

If I want to vote my shares in person at the Annual Meeting, what must I do?

If you attend the Annual Meeting, hold your shares directly in your own name, and wish to vote in person rather than by proxy, we will give you a ballot when you arrive. However, if you hold your shares in street name, you must obtain a proxy from your broker or bank assigning to you the right to vote your shares. You must submit your proxy with your ballot to vote your shares in person.

If I want to vote my shares electronically during the Annual Meeting, what must I do?

If you attend the Annual Meeting online, you will need to provide your 12-Digit Control Number, located on your proxy voting card, which identifies you as a stockholder of record. Stockholders voting via the Internet will need to follow the instructions at www.proxyvote.com or www.virtualshareholdermeeting.com/awk2013 in order to vote or submit questions at the Meeting. Voting in person or via the Internet by a stockholder will replace any previous votes submitted by proxy.

We encourage you to take advantage of the option to vote your shares electronically through the Internet or telephone. By furnishing proxy materials to stockholders via the Internet, we are able to provide our stockholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of the Annual Meeting.

What are my choices when voting?

You may specify whether your shares should be voted for or against, or whether you abstain from voting with respect to each of the director nominees specified in this proxy statement for election as directors. You also may specify whether your shares should be voted for or against, or whether you abstain from voting with respect to each of the other proposals. If you sign and return a proxy card, one of the individuals named on the proxy card will vote your shares as you have directed.

What if I do not specify how I want my shares voted?

If you are a stockholder of record and return a signed proxy card, or if you give your proxy by telephone or over the Internet, but do not provide voting instructions, one of the individuals named on your proxy card will vote your shares in accordance with the board’s recommendations described above. Please see the discussion below under “What vote is required to elect directors?” and “What vote is required to approve the other proposals?” for further information on the voting of shares.

How can I revoke my proxy or substitute a new proxy or change my vote?

If you are a record holder, you can revoke your proxy as follows:

For a proxy submitted by internet or telephone

• Submitting in a timely manner a later-dated proxy in person at the meeting or through the Internet or by telephone; or

• Voting in person at the Annual Meeting.

4

For a proxy submitted by mail

• Subsequently executing and mailing another proxy card bearing a later date; or

• Giving written notice of revocation to American Water’s Secretary at 1025 Laurel Oak Road, Voorhees, NJ 08043 that is received by the Secretary prior to the Annual Meeting;

• Voting in person at the Annual Meeting; or

• Casting your vote at the Virtual Stockholder Meeting during the live meeting before the polls are closed. See “What is required to attend the Annual Meeting” for information on voting at the Virtual Stockholder Meeting.

If your shares are held in street name, contact your bank or broker.

What vote is required to elect directors?

Directors will be elected by the vote of the majority of votes cast. For this purpose, a majority of the votes cast means that the number of shares voted for a director must exceed the number of shares voted against the director.

What vote is required to approve other proposals?

Approval of other proposals requires the affirmative vote of a majority of the votes cast at the meeting. Abstentions are counted as votes “against” a proposal, and broker non-votes are not counted as votes for or against the proposals. A “broker non-vote” occurs when a broker holding shares for the account of a beneficial owner is not permitted to vote on a matter because the broker has not received voting instructions from the beneficial owner. Under New York Stock Exchange rules, brokers are not permitted to vote on the election of directors and the advisory vote on executive compensation; brokers may vote on these matters only if you provide voting instructions.

Who counts the votes?

A representative from Broadridge Financial Solutions, Inc., an investor communications service, will serve as our inspector of election. In that capacity, Broadridge will tabulate the votes and certify the results.

How do I obtain the voting results?

Preliminary voting results will be announced at the Annual Meeting, and a webcast of our meeting will be archived on the Events and Presentation page which can be accessed through our Investor Relations page at www.ir.amwater.com through June 11, 2013. Preliminary or, if then available, final voting results will be published in a Current Report on Form 8-K that we will file with the SEC within four business days after the meeting ends. If only preliminary voting results are available within four business days following the meeting date, we will file an amendment to the Form 8-K to provide final voting results within four business days following the receipt of those results. A copy of the Form 8-K and any amendment that we file will be available on the SEC Filings page of our web site after it is filed with the SEC, or can be obtained by calling Investor Relations at 877-310-7174 and requesting a copy. To access the SEC Filings page, click on the Financial Reports link on our Investor Relations page and then click on the link that says “SEC filings.”

Can American Water deliver only one set of Annual Meeting materials to multiple stockholders who share the same address?

Yes. The SEC’s rules regarding the delivery to stockholders of Notices and annual reports permit us to deliver a single copy of these documents to an address shared by two or more of our stockholders. This method

5

of delivery is called “householding,” and can significantly reduce our printing and mailing costs. It also reduces the volume of mail you receive. This year, we may deliver only one Notice, or if applicable, one proxy statement and Annual Report to Stockholders to multiple stockholders sharing a single address, unless we receive instructions to the contrary from one or more of the stockholders. If you would like to receive more than one copy of the Notice, or if applicable, the proxy statement and our Annual Report to Stockholders, we will promptly send you additional copies upon written or oral request to Kellye L. Walker, Chief Administrative Officer, General Counsel and Secretary, American Water Works Company, Inc., 1025 Laurel Oak Road, Voorhees, New Jersey, 08043, telephone: 856-346-8200. The same phone number and address may be used to notify us that you wish to receive a separate Notice, or if applicable, annual report or proxy statement in the future, or to request delivery of a single copy of the Notice, or if applicable, annual report or proxy statement if you are receiving multiple copies.

Who will pay the costs for proxy solicitation?

We will pay the costs of the solicitation of proxies. We will also pay the fees of brokerage firms and other nominees of beneficial owners associated with their provision of the Notice, forwarding of proxy materials to beneficial owners and obtaining beneficial owners’ voting instructions.

In addition to soliciting by e-proxy and by mail, our directors, officers and employees also may solicit by telephone, telecopy or in person. We will pay for the cost of these solicitations, but these individuals will receive no additional compensation for their solicitations.

(Proposal 1)

ELECTION OF DIRECTORS

Our board currently consists of nine directors. All of our current directors have been nominated for election this year to hold office until the 2014 Annual Meeting of Stockholders or until their successors are elected and qualified. The board of directors believes that these nominees will be able to serve as directors if elected. If a nominee is not able to serve, proxies will be voted for another person nominated by the board of directors, unless the board of directors reduces the number of directors.

Our bylaws require that in order to be elected, a director nominee must receive a majority of the votes cast with respect to the nominee in uncontested elections (for this purpose, a majority of the votes cast means that the number of shares voted “for” a director nominee must exceed the number of votes cast “against” that nominee). Each of our director nominees is currently serving on the board of directors. If a nominee who is currently serving as a director is not re-elected, Delaware law provides that the director would continue to serve on the board of directors as a “holdover director.” Under our bylaws and corporate governance guidelines, each incumbent director nominee submits, prior to an annual meeting of stockholders, a contingent resignation that the board of directors may accept if stockholders do not re-elect the director. In that situation, our nominating/corporate governance committee would make a recommendation to the board of directors on whether to accept or reject the resignation, or whether to take other action. The board of directors would act on the resignation, taking into account the nominating/corporate governance committee’s recommendation, and publicly disclose its decision and the rationale behind it within 90 days from the date that the election results were certified.

Nominees for Election as Directors

Stephen P. Adik, 69, Director since 2009 Mr. Adik has been a member of our board of directors since June 2009. Mr. Adik most recently served as the Vice Chairman, Executive Vice President and Chief Financial Officer of NiSource, Inc., an electric, natural gas and pipeline company operating in 16 states, until his retirement in December 2003. Mr. Adik previously held leadership positions with the American Natural Resources Company, Lehigh Valley Railroad, Amtrak, Chicago & North Western Railroad and Chesapeake & Ohio Railroad. Mr. Adik is a member of the board of directors and Chair of the audit committee of Northwestern Energy.

In addition, Mr. Adik served on the board of directors of Beacon Power Corporation, where he served on the audit committee, until resigning in November 2010. Mr. Adik received a Bachelor of Science degree in Mechanical Engineering from the Stevens Institute of Technology, and an MBA degree in Finance from Northwestern University. Key Attributes, Experience and Skills: Mr. Adik’s long executive experience with an energy-related company and additional extensive experience in leadership positions with regulated entities enable him to assist the full board in assessing government regulatory considerations. In addition, his experience as a financial executive enables him to provide knowledgeable perspectives on financial matters.

Determination of Independence of Directors

The board of directors is, among other things, responsible for determining whether each of the directors is “independent” within the meaning of New York Stock Exchange, which we refer to as the “NYSE,” listing standards. In addition, the board of directors has adopted the following categorical standards to assist it in making independence determinations. Under these standards a director is not independent if:

• the director is, or has been within the last three years, an employee of American Water, or an immediate family member of the director is, or has been within the last three years, an executive officer of American Water. (Employment as an interim CEO or other officer will not disqualify a director from being considered independent following that employment.);

• the director or an immediate family member of the director is a current partner of a firm that is our internal or external auditor; the director is a current employee of the firm; an immediate family member of the director is a current employee of the firm and personally works on our audit; or the director or an immediate family member of the director is a former partner or employee of such a firm and personally worked on our audit within the last three years;

• the director or an immediate family member of the director is, or has been within the last three years, employed as an executive officer of another company where any of our present executive officers at the same time serves or served on that company’s compensation committee;

• the director or an immediate family member of the director received, during any 12 month period within the last three years, more than $120,000 in direct compensation from us, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service). (Compensation received by a director for former service as an interim CEO or other executive officer need not be considered in determining independence under this test. Compensation received by an immediate family member for service as an employee of us (other than an executive officer) need not be considered in determining independence under this standard.);

• the director is a current employee or holder of more than 10 percent of the equity of another company, or an immediate family member of the director is a current executive officer or holder of more than 10 percent of the equity of another company, that has made payments to, or received payments from, us in any of the last three fiscal years of the other company, that exceeds the greater of $1 million or two percent of such other company’s consolidated gross revenues; or

• the director is a current executive officer of a charitable organization to which we have made charitable contributions in any of the charitable organization’s last three fiscal years that exceed the greater of $1 million or two percent of that charitable organization’s consolidated gross revenues.

For purposes of the categorical standards set forth above, (a) a person’s immediate family includes a person’s spouse, parents, children, siblings, mother- and father-in-law, sons- and daughters-in-law, and brothers- and sisters-in-law and anyone (other than domestic employees) who shares such person’s home, and (b) the term “executive officer” has the same meaning as specified for the term “officer” in regulations under Section 16 of the Securities Exchange Act of 1934.

The Company’s board of directors has affirmatively determined that each of Stephen P. Adik, Martha Clark Goss, Julie A. Dobson, Paul J. Evanson, Richard R. Grigg, Julia L. Johnson, George MacKenzie and William J. Marrazzo is independent.

Executive Sessions of Independent Directors

The board meets at regularly scheduled executive sessions without members of management present. Mr. MacKenzie, our board chairman, presides over these sessions.

14

Board Leadership Structure

Our corporate governance guidelines currently provide that the chairman of the board is to be an independent director. We believe that the oversight function of the board of directors is enhanced when an independent director, serving as chairman, is in a position to set the agenda for, and preside over, meetings of our board. We also believe that our leadership structure enhances the active participation of our independent directors.

Board Role in Risk Oversight

The board administers its risk oversight function principally through our finance committee and also through our audit committee and compensation committee. The finance committee oversees our enterprise risk management process. To gain an understanding of the magnitude of risks and to consider approval of risk management policies, the finance committee receives quarterly reports from management regarding our major financial and operational risk exposures and management’s activities to monitor and mitigate these exposures. In addition, our audit committee routinely discusses our policies with respect to risk assessment and risk management. To assist the audit committee in addressing these matters, the finance committee reports to the audit committee at least annually regarding finance committee activities relating to enterprise risk management. In this regard, the chairman of the finance committee meets annually with management and the audit committee. The compensation committee also considers risk in the context of our incentive compensation programs and practices.

The board regularly receives reports with regard to the board committee risk assessments described above.

Code of Ethics

We have a Code of Ethics applicable to our directors, officers and employees. Among other things, the Code of Ethics is designed to deter wrongdoing and to promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships; to promote full, fair, accurate, timely and understandable disclosures in periodic reports we are required to file; and to promote compliance with applicable governmental laws, rules and regulations. The Code of Ethics provides for the prompt internal reporting of violations of the Code to an appropriate person identified in the Code and contains provisions regarding accountability for adherence to the Code. The Code of Ethics is available at the website address listed above, or can be requested, free of charge, by writing to the Office of the Secretary, American Water Works Company, Inc., 1025 Laurel Oak Road, Voorhees, New Jersey 08043. We intend to satisfy the disclosure requirements regarding any amendment to, or waiver from, a provision of the Code of Ethics by making disclosures concerning such matters available on the Investor Relations page of our website.

Assessment of Board and Committee Performance

The board conducts annual assessments regarding the performance of the board of directors and board committees.

Stockholder Communications to the Board

Stockholders may communicate directly with the board of directors or individual members of the board of directors by submitting written correspondence to American Water Board of Directors, 1025 Laurel Oak Road, Voorhees, New Jersey 08043 or via email: contacttheboard@amwater.com.

Our “whistleblower” policy prohibits American Water or any of its employees from retaliating or taking any adverse action against anyone for raising a concern in good faith. If an interested party nonetheless prefers to raise his or her concern to the board in a confidential or anonymous manner, the concern may be directed to our confidential ethics hotline at 877-207-4888. Such matters raised on the hotline are investigated by the Ethics and Compliance Department and reviewed by the chair of the audit committee.

15

Board and Board Committee Meetings

During 2012, our board of directors held nine meetings. In addition, there were six audit committee meetings, eight compensation committee meetings, six nominating/corporate governance committee meetings and four finance committee meetings. Some of these meetings were conducted by telephone conference. All of the incumbent directors attended at least 75 percent of the total number of meetings of the board and board committees of which the director was a member during 2012. Although we do not have a formal policy regarding board member attendance at the annual meeting, we do encourage their attendance, and all of the directors attended last year’s annual meeting.

Committees of the Board of Directors

Our board of directors conducts its business through four standing committees: the audit committee, the compensation committee, the finance committee and the nominating/corporate governance committee. In addition, from time to time, special committees may be established under the direction of our board of directors. All of the current committees of the board are comprised of directors who have been determined by our board of directors to be independent under currently applicable listing standards of the NYSE, and in the case of members of the audit committee, to have satisfied additional independence requirements applicable to audit committee members. Each of the board’s four standing committees operates in accordance with the terms of a written charter, and each committee has the authority to retain outside advisors, including legal counsel or other experts, as it deems appropriate in its sole discretion and to approve the fees and expenses associated with such advisors.

The table below provides membership information for each board committee:

Director	Audit	Compensation	Nominating/ Corporate Governance	Finance
Stephen P. Adik	ü			ü
Martha Clark Goss	Chair			ü
Julie A. Dobson		ü	ü
Paul J. Evanson		ü		ü
Richard R. Grigg			ü	Chair
Julia L. Johnson		ü	Chair
William J. Marrazzo	ü	Chair

Audit Committee

Our audit committee consists of Ms. Clark Goss (Chair) and Messrs. Adik and Marrazzo. Our board of directors has determined that each member of the audit committee is an “audit committee financial expert,” within the meaning of SEC regulations. The audit committee operates under a written charter, which is available at the website address provided above. The audit committee has responsibility for, among other things:

• appointing the independent registered public accounting firm to audit the consolidated financial statements of American Water and its subsidiaries;

• reviewing and discussing with management and the independent auditors the results of the audit of the consolidated financial statements;

• reviewing any significant deficiency or material weakness in the design or operation of internal accounting controls identified by the independent auditors;

• reviewing all alternative accounting treatments of financial information within generally accepted accounting principles that have been discussed with management;

16

• reviewing and discussing SEC filings with management and, to the extent that such filings contain financial information, with the independent auditors;

• discussing earnings press releases, as well as financial information and earnings guidance, if any, provided to analysts and ratings agencies;

• at least annually, discussing with the chair of the finance committee and management, our policies with respect to risk assessment and risk management, our major financial risk exposures and the steps management has taken to monitor and control these exposures;

• overseeing management’s ethics and compliance program and reviewing reports from our chief ethics and compliance officer;

• overseeing the internal audit function and reviewing the reports of any internal auditor with respect to any financial safeguard problem that has not resulted in corrective action or otherwise been resolved to the internal auditors’ satisfaction; and

• reviewing with the General Counsel any legal matter that could have a significant impact on our financial statements.

Compensation Committee

Our compensation committee consists of Messrs. Marrazzo (Chair) and Evanson and Mses. Dobson and Johnson. The compensation committee operates under a written charter, which is available at the website address provided above. The compensation committee has responsibility for, among other things:

• establishing and reviewing our overall compensation philosophy;

• reviewing and recommending to the board of directors the corporate goals and objectives relevant to the CEO’s compensation, the CEO’s performance in light of the goals and objectives approved by the board of directors and the compensation for our CEO, including annual base salary and annual and long-term performance-based compensation opportunities;

• approving, after receiving the CEO’s recommendations and consulting with the CEO, the annual base salary and annual and long-term performance-based opportunities for our other executive officers, and the actual awards of performance-based compensation for our other executive officers;

• annually reviewing other benefit plans and perquisites;

• annually reviewing and recommending to the board of directors the form and amount of director and chairman compensation;

• reviewing and making recommendations to our board of directors, or approving, all awards of stock or stock options pursuant to our equity-based plans; and

• at least annually, reviewing and making recommendations to the board of directors regarding the compensation related risk assessment of our compensation policies and practices.

In addition, the compensation committee annually reviews our short- and long-term incentive plans to ensure that they have the appropriate mix of fixed and at-risk components.

The compensation committee adopted a policy under which it will use only compensation consultants that are independent of American Water. A compensation consultant is deemed independent under the policy if the compensation consultant:

• is retained by the compensation committee, and reports solely to the compensation committee in connection with the compensation committee’s discharge of its duties and responsibilities; and

• does not provide any other services or products to American Water or its management.

17

The compensation committee also will perform an annual assessment of its compensation consultants’ independence.

In February 2011, the compensation committee retained the Hay Group as its independent compensation consultant, referred to below as “Hay Group”, to assist the compensation committee with respect to executive and director compensation and, to a lesser extent, enterprise compensation matters in general. The Hay Group did not provide any other services to us or our management.

Nominating/Corporate Governance Committee

Our nominating/corporate governance committee consists of Mses. Johnson (Chair) and Dobson and Mr. Grigg. The nominating/corporate governance committee operates under a written charter, which is available at the website address provided above. The nominating/corporate governance committee has responsibility for, among other things:

• establishing criteria for the selection of new directors to serve on our board of directors;

• identifying qualified candidates to serve on our board of directors and recommending their election to our board of directors;

• making recommendations to our board of directors as to whether members of our board of directors should stand for re-election;

• developing and recommending to our board of directors our corporate governance guidelines, assessing those guidelines annually and making recommendations to our board of directors in light of such assessments as may be appropriate; and

• reviewing the composition of each committee of the board of directors and recommending appropriate changes to the committees.

We believe that the backgrounds and qualifications of our directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will enable the board of directors to fulfill its responsibilities. Therefore, the nominating/corporate governance committee considers diversity in identifying nominees for directors. In this regard, the nominating committee views diversity in a broad sense, including on the basis of business experience, public service experience, gender and ethnicity. In addition, our corporate governance guidelines provide that members of the board must be persons of good character and thus must possess all of the following personal characteristics:

• Integrity: Directors must demonstrate high ethical standards and integrity in their personal and professional dealings.

• Accountability: Directors must be willing to be accountable for their decisions as directors.

• Judgment: Directors must possess the ability to provide wise and thoughtful counsel on a broad range of issues.

• Responsibility: Directors must interact with each other in a manner which encourages responsible, open, challenging and informed discussion.

• High Performance Standards: Directors must have a history of achievement which reflects high standards for themselves and others.

• Commitment and Enthusiasm: Directors must be committed to, and enthusiastic about, their performance for American Water as directors, both in absolute terms and relative to their peers.

• Courage: Directors must possess the courage to express views openly, even in the face of opposition.

18

Our corporate governance guidelines also state that the board of directors should strive to have members with knowledge, experience and skills in the following core competencies: accounting and finance, business judgment, management, crisis response, industry knowledge, utility regulation, leadership and strategy/vision. In this regard, in evaluating a candidate’s experience and skills, the nominating/corporate governance committee will consider qualities such as an understanding of the water industry, utilities, marketing, finance, utility and environmental regulation and public policy issues. The nominating/corporate governance committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees.

In addition, the board is committed to being comprised of directors that add tangible value to the Company with a diversity of ideas, approaches and experiences and the interpersonal capacity to foster effective communication within, and operation of, the board and with management. Annually, the nominating/corporate governance committee reviews the profile, engagement and performance of each director to determine whether they should be renominated for board service. They also consider whether, in light of the Company’s strategy or trends in our market environment, new skill sets or experience would benefit the Company and our stockholders. The board believes in balancing the value that longevity of director service can bring to the Company with the value of new ideas and insights that can come through new members.

The process followed by the nominating/corporate governance committee to identify and evaluate candidates includes requests to members of the board of directors and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by members of the nominating/corporate governance committee and other members of the board of directors. The nominating/corporate governance committee may engage a third party to assist in the search for director candidates or to assist in gathering information regarding a director candidate’s background and experience. If the nominating/corporate governance committee engages a third party, the nominating/corporate governance committee approves the fee that American Water pays for these services.

The nominating/corporate governance committee also will consider qualified director candidate recommendations by stockholders. A stockholder’s recommendation should be sent to: Office of the Secretary, American Water Works Company, Inc., 1025 Laurel Oak Road, Voorhees, NJ 08043. The recommendation must include the following information:

• the name, age, business address and residence address of the candidate;

• a resume describing the candidate’s qualifications;

• other information about the candidate that would be required to be included in a proxy statement under the rules of the SEC;

• a description of all arrangements or understandings relating to the nomination between or among the stockholder, the candidate and any other person or persons;

• the signed consent of the candidate to serve as a director if elected;

• the name and address of the stockholder who is submitting the recommendation; and

• evidence of the number of shares of American Water’s common stock that the recommending stockholder owns and the length of time the shares have been owned.

The nominating/corporate governance committee may seek additional information regarding the candidate. The committee will consider all potential candidates in the same manner regardless of the source of the recommendation.

19

Finance Committee

Our finance committee consists of Messrs. Grigg (Chair), Evanson and Adik and Ms. Clark Goss. The finance committee operates under a written charter, which is available at the website address provided above. The finance committee is responsible for, among other things, monitoring, reviewing and evaluating:

• our financial forecasts, financial condition and our anticipated financing requirements;

• our capital structure and proposed short-and long-term changes in our capital structure, including changes resulting from new issuances, purchases or redemptions of debt and equity securities;

• our capital expenditure plan and strategies;

• our dividend payment policy and any proposed changes;

• the investment performance of the assets held under our employee benefits plans, and the investment guidelines of the Retirement/Benefits Plan Committee;

• our plans and strategies relating to the divestiture or disposition of assets;

• our cash management plans and strategies; and

• our growth opportunities, including acquisitions and business development proposals.

In addition, the finance committee oversees our enterprise risk management process and our insurance risk management policies and programs and approves our debt issuances within limits authorized by the board in our business plan.

DIRECTOR COMPENSATION

In 2012, our non-employee directors received compensation for their services as described below:

Annual Retainer Fees (payable in quarterly installments):
•    Chairman of the Board	$	115,000
•    Chairs of the Audit Committee and the Compensation Committee	$	80,000
•    Chairs of the Nominating/Corporate Governance Committee and the Finance Committee	$	70,000
•    Other non-employee directors	$	60,000

Meeting Fees:

• No separate fee for attendance at board of directors’ meetings

• $1,500 for each board committee meeting attended

The non-employee directors are reimbursed for expenses incurred in attending board and committee meetings.

In addition, each non-employee director and the Chairman of the Board receives annual equity compensation of $60,000 and $115,000, respectively in stock units. The actual number of stock units granted is based on the closing price of our common stock on the date of grant, as reported on the NYSE Composite Tape. The stock units vest on the date of grant and the shares underlying the stock units typically are distributed to the directors 15 months after the date of grant.

20

We have a stock retention policy for directors under which each director is required to hold shares equaling four times the director’s annual cash retainer by the later of February 2015 or the fifth anniversary of the commencement of service as a director.

The Company established the Nonqualified Deferred Compensation Plan for Non-Employee Directors under which directors may defer up to 100 percent of their annual retainer and meeting fees on a tax-deferred basis. Directors may elect to receive their deferrals upon (i) separation from service, (ii) a specified date, (iii) the earlier of separation from service or a specified date or (iv) the later of separation from service or a specified date or, if earlier, a change in control, and may elect to receive their deferrals in the form of a lump sum or annual installments paid over a period of between two and 10 years. Amounts will be paid earlier upon the death of a director. Directors are immediately vested in their contributions to the plan. Accounts of directors are credited with returns in accordance with the deemed investment options elected by the director.

The following table provides information regarding compensation for our non-employee directors. The table does not include amounts paid for reimbursement of travel expenses related to attending board and board committee meetings, and does not include compensation paid to Jeffry E. Sterba, our President and Chief Executive Officer. See “Executive Compensation” for information relating to Mr. Sterba’s compensation.

COMPENSATION DISCUSSION AND ANALYSIS

In this Compensation Discussion and Analysis, we address the compensation paid or awarded to the five executive officers listed in the 2012 Summary Compensation Table that follows this discussion, whom we refer to as our named executive officers or “NEOs.”

EXECUTIVE SUMMARY

Our executive compensation program is designed to reward our named executive officers for delivering results and building long term sustainable value for our shareholders. We believe our program’s performance measures align the interests of our stockholders and the NEOs by correlating pay to our short-term and long-term performance. Despite the continuing challenging economic environment, we were able to deliver strong performance results in 2012, which was reflected in our share price and in our compensation outcomes.

Compensation Objectives

Our compensation objectives remain largely unchanged in 2012, subject to one important modification. The significance of our business transformation project has caused us to increase our focus on that project in connection with compensatory determinations. Accordingly, we focused on the following objectives in making compensation decisions in 2012:

• Promote our success in achieving both superior financial performance and outstanding non-financial performance relating to the business transformation project, environmental compliance, customer service and satisfaction and workplace safety.

• Compensate our executive officers at competitive levels that reflect their responsibilities and contributions, with a focus on pay for performance and the compensation environment in our peer group and the utilities industry generally.

• Condition a significant portion of a named executive officer’s total compensation on a combination of short and long-term performance, with a proportionately greater emphasis on long-term performance-based compensation than on annual incentive compensation.

• Align executive officer and stockholder interests as an incentive to increase stockholder value by requiring the maintenance of meaningful equity ownership.

Components of Compensation

For 2012, there were three key elements of compensation we used to carry out our compensation objectives: Base Salaries, Annual Incentive Plan (AIP) and Long-Term Incentive Plan (LTIP). The following graphic represents the percentage of total compensation for each of these elements (assuming annual and long-term incentive awards are paid at target levels) for our President and CEO and the average percentage of total compensation for each of these elements for the other NEOs as a group in 2012:

24

In addition, we provide employee retirement and health and welfare benefit plans, as well as an executive severance policy. We designed the plans and policy to provide competitive levels of medical, retirement and income protection, such as deferred compensation programs, life and disability insurance coverage, and severance benefits if an executive officer’s employment is terminated under various circumstances other than for cause.

Base Salaries

For 2012, salaries for some of our NEOs were increased as follows:

• Mr. Sterba received a $75,000 increase under his new employment agreement, from $675,000 to $750,000

• Ms. Walker and Messrs. Lynch and Bigelow received merit increases, ranging from 1.0% to 2%

Annual Incentive Plan

The AIP is designed to motivate eligible participants to help us achieve our annual business objectives by providing an opportunity to earn cash award payouts that are tied to corporate and individual performance. During the last four years, each of our NEOs annual incentive compensation has been based upon his or her target award times a percentage amount we call the “Corporate Multiplier.” The Corporate Multiplier represents the sum of six percentage amounts, each determined based upon our level of achievement against company-wide performance measures. Of the six performance measures, a financial measure, earnings per share, constitutes 55 percent of the target Corporate Multiplier and non-financial measures constituted the remaining 45 percent. At target performance, the Corporate Multiplier equals 100 percent.

We believe that the measures used in computing the amount of the Corporate Multiplier collectively are strong indicators of our overall performance and, therefore, effectively tie pay to performance. The 2012 Corporate Multiplier was determined as follows:

Performance Measure	Percentage Amount at Target for Inclusion in the Corporate Multiplier			Target	Actual Performance	Percentage Amount Included in Calculation of Corporate Multiplier Based on Actual Performance
EPS(1)		55.0	%	$1.92	$2.09		82.5	%
Business Transformation Performance		15.0	%	Discretionary Award	N/A		16.5	%
Environmental Compliance		7.5	%	17 NOVs	7 NOVs		11.3	%
Safety Performance(2)		7.5	%	3.35 ORIR	2.95 ORIR		0.0	%
Service Quality		7.5	%	85% of Surveyed Customers	89% of Surveyed Customers		10.5	%
Customer Satisfaction		7.5	%	90% of Surveyed Customers	93% of Surveyed Customers		9.8	%
					TOTAL		130.6	%(3)

(1) As adjusted to eliminate the impact of (a) the sale of certain subsidiaries and (b) costs associated with organizational streamlining.

(2) In light of two employee fatalities on the job, the Safety Performance percentage amount was reduced to zero at the recommendation of Mr. Sterba.

(3) The corporate multiplier of 130.6% was adjusted, for purposes of awards to NEOs, to 129.4% due to the allocation of $200,000 to creation of a special award pool for non-executive officers.

Long-Term Incentives

The LTIP is designed to motivate eligible participants to help us achieve our long-term business objectives by providing an opportunity to earn equity awards that are tied to our long-term goals and continued employment with the Company. Our LTIP for 2012 included stock option grants and performance stock units, or “PSUs.” As described in more detail below, the extent to which shares of our common stock are issued with respect to the PSUs is based on our achievement, over a three-year period, relative to three performance measures. The three performance measures for 2012 were total shareholder return, operational efficiency improvement and compounded EPS growth.

As in the past, we based the target value of LTIP awards on a percentage of the NEOs salary. The compensation committee applied 40 percent of a NEO’s LTIP target award to stock options and 60 percent to PSUs. We bifurcated long-term compensation in this manner because we believe it provides an appropriate balance between two related but discrete goals. Stock options are designed to align the executive officer’s interests with stockholder interests, since the intrinsic value of stock options is a function of the appreciation of our stock price. As explained in more detail below, the PSUs are designed to encourage long-term performance both from the standpoint of favorable stock performance in relation to the other 69 companies in the Dow Jones U.S. Utilities Index (which we refer to as the “Comparator Group”), and from the standpoint of specific company-wide performance measures. We chose to provide the larger percentage weighting for PSUs because we believe the greater emphasis should be on out-performing similarly situated companies and on the satisfaction of long-term operational goals.

In 2010, we granted PSUs to our executives and other employees for which the performance period ended in 2012. The number of shares ultimately issued with respect to the PSUs was based on our performance relative to four separate measures: Total Stockholder Return, Operational Efficiency Improvement, Compounded EPS Growth and Increase in Population Served. A number of shares equal to 175% of the PSUs granted with respect to all measures other than Increase in Population Served were performance vested. There was no payout for the Increase in Population Served measure.

For further information, see “2012 Compensation—Long-Term Incentive Plan,” below.

Stockholder Advisory Vote

At our 2012 annual meeting our stockholders approved, on an advisory basis, the compensation of our NEOs. The stockholder vote in favor of NEO compensation totaled approximately 98.7 percent of the votes cast (including abstentions). As a result, we determined that no specific action need be taken in response to the vote.

Recent Enhancements

During 2012, the compensation committee, and its independent consultant, with the support of management reevaluated our compensation plans, and made some modest adjustments to the weighting of certain targets in our incentive plans to ensure the proper focus is placed on the business transformation project we are undertaking.

COMPENSATION DETERMINATIONS AND PAY COMPETITIVENESS IN 2012

For 2012, the compensation committee reviewed all compensation paid to our executive officers other than cash compensation for Mr. Sterba, our President and Chief Executive Officer, which was approved by the independent members of the board of directors, after consideration of the recommendation of the compensation committee. Mr. Sterba did not participate in the compensation committee’s decision-making regarding his own compensation and was excused from those portions of the meetings during which his compensation was determined.

26

The compensation committee considered Mr. Sterba’s assessment of the performance of the other executive officers and his compensation recommendations regarding each executive officer’s AIP award. The compensation committee, with Mr. Sterba’s participation, discussed the performance of each executive officer, and then approved Mr. Sterba’s recommendations.

In making executive compensation determinations for 2012, we referenced data provided by Hay Group to gauge the comparability of our compensation to the compensation of executives of other companies with generally corresponding responsibilities. Hay Group has served as an independent consultant to the compensation committee since early 2011, and assists the compensation committee in its review of compensation for executive officers. Hay Group does not perform any other services for us.

The compensation consultant provided data to the compensation committee focused on compensation paid by a peer group of 16 companies that had revenues in the range of approximately 53 to 168 percent of our revenues. We believe there is a strong likelihood that an executive officer’s skills will be transferable among these companies, so we would expect to compete with these companies for executive officer talent. The comparator companies were the following:

•       AGL Resources, Inc.	•       NV Energy, Inc.	•       Vectren Corp.
•       Alliant Energy Corp.	•       Piedmont Natural Gas Company, Inc.	•       Weststar Energy, Inc.
•       Atmos Energy Corp.	•       Pinnacle West Capital Corp.	•       WGL Holdings, Inc.
•       DPL Inc.	•       PNM Resources, Inc.	•       Wisconsin Energy Corp.
•       Great Plains Energy, Inc.	•       SCANA Corp.
•       Northeast Utilities	•       TECO Energy, Inc.

While the compensation committee reviewed and discussed the data with Hay Group for purposes of benchmarking, it was only a part of the information considered by the compensation committee in its determinations regarding our NEOs compensation. For instance, the compensation committee also considered other information provided by Hay Group, such as survey data and data compiled from other U.S. publicly traded water utilities. The compensation committee referenced all this data to obtain an understanding of general industry, utility industry and peer group compensation practices.

2012 COMPENSATION

The NEOs listed in the 2012 Summary Compensation Table are:

• Jeffry E. Sterba, President and Chief Executive Officer

• Ellen C. Wolf, Senior Vice President and Chief Financial Officer

• Walter J. Lynch, President and Chief Operating Officer, Regulated Operations

• Kellye L. Walker, Chief Administrative Officer, General Counsel and Secretary

• John R. Bigelow, Senior Vice President of Business Services

Base Salaries

For 2012, salaries for some of our NEOs were increased as follows:

• Mr. Sterba received a $75,000 increase under his new employment agreement, from $675,000 to $750,000

• Ms. Walker and Messrs. Lynch and Bigelow received merit increases, ranging from 1.0% to 2%

Annual Incentive Plan

The AIP is designed to motivate eligible participants to help us achieve our annual business objectives by providing an opportunity to earn cash award payouts that are tied to corporate and individual performance. The metrics chosen for 2012 reflected our primary objectives for financial performance, business transformation implementation, environmental stewardship, safety, customer satisfaction and service quality. We maintained earnings per share as our financial performance measure because we continue to believe this measure has a meaningful effect on stockholder value. The 2012 target award opportunities for participants are expressed as a percentage of each participant’s base salary, based on the individual’s position with American Water. The actual payout may be lower or higher than the target award opportunity depending, in the case of the NEOs, on corporate and individual performance against specific goals. Cash awards under the AIP are distributed to participants in March following the performance year.

As in past years, awards under the AIP were determined in the following manner:

• We established a target pool for all payouts under the AIP. Specifically, the compensation committee approved AIP target awards for all participants, based on a percentage of the participating employees’ respective salaries. Participating employees in higher pay grades generally have a higher percentage of their salary designated as the target award than participating employees in lower pay grades. The target pool was equal to the sum of all participants’ target award opportunities.

• The total pool actually available for payouts under the AIP was determined by multiplying the target pool by a percentage we call the Corporate Multiplier. For 2012, the Corporate Multiplier represented the sum of six percentage amounts, each determined based upon our level of achievement against, company-wide performance measures that, with one exception, are objective. Of the six performance measures, one was a financial measure (55 percent of the target Corporate Multiplier) and five were non-financial measures (45 percent of the target Corporate Multiplier). The Corporate Multiplier could have ranged from 0 percent to 150 percent of the target Corporate Multiplier, depending on how well we performed against the financial and non-financial measures. For 2012, the Corporate Multiplier was 130.6 percent. The actual percentage included in the Corporate Multiplier with respect to each performance measure is set forth in the Corporate Multiplier Table below under the caption, “Determination of the Corporate Multiplier.”

• Once the board determined the actual award pool, the pool was allocated among various organizational groups, including a pool for the executive group (which consisted of all NEOs; however, part of

28

Mr. Lynch’s award was funded through the pool for regulated operations, as described under the caption “Determination of Individual AIP Awards for NEOs”). The executive group pool was equal to the product of the Corporate Multiplier times the sum of all individual AIP target awards in the executive group, which are described immediately below.

• Each individual participant is assigned an AIP award, based on the individual’s position with American Water and individual performance. The AIP target award is expressed as a percentage of the individual’s base salary. The individual’s award may range from 0 percent to 200 percent of the AIP target award.

Determination of the Corporate Multiplier

We discuss in this section the performance measures used to determine the Corporate Multiplier. Following the discussion of each performance measure is a table that indicates (i) the minimum performance threshold requirement for the measure, (ii) the performance required for achievement of the target, and (iii) the performance required to achieve the maximum contribution to the Corporate Multiplier for that measure. The table also shows the percentage that would be included in the Corporate Multiplier for such threshold, target and maximum performance. If the minimum performance threshold requirement for a performance measure was not met, no additional percentage was added to the Corporate Multiplier with respect to that measure. No funding of the AIP would have occurred if EPS had been below $1.73, which is 90 percent of the target EPS ($1.92).

Financial Performance Measure (55 percent of target Corporate Multiplier)

EPS (55 percent of target Corporate Multiplier)

EPS means diluted earnings per share. For a large, well established public utility such as American Water, EPS is a key metric affecting our stock price. In addition, increasing EPS enhances our capacity to raise the financing necessary to make prudent capital improvements in our water and wastewater systems. Therefore, we view EPS as a very important measure for creating value for our stockholders and for enabling us to enhance our services to our customers. For 2012, EPS was adjusted as described below in footnote 1 to the Corporate Multiplier Table. We increased the weighting of EPS from 50 percent to 55 percent of the target Corporate Multiplier in 2012, as a result of our determination to eliminate the operating cash flow metric previously used (which formerly represented 20 percent of the target Corporate Multiplier) and allocate 15 percent of the target Corporate Multiplier to a new non-financial measure, Business Transformation Performance, which is discussed below. Since our earnings are predominately cash earnings, EPS is also a good indicator of our cash from operations. Thus, we determined to eliminate operating cash flow as a performance measure.

Threshold (13.75% to be Included in Corporate Multiplier)	Target (55.0% to be Included in Corporate Multiplier)	Maximum (82.5% to be Included in Corporate Multiplier)
$1.81	$1.92	$1.98

Non-Financial Performance Measures (45 percent of target Corporate Multiplier)

Business Transformation Performance (15 percent of target Corporate Multiplier)

We have undertaken a business transformation project, which is intended to improve our business processes and upgrade our antiquated core information technology systems. This multi-year, enterprise-wide initiative supports our broader strategic initiatives. The project is intended to optimize workflow throughout our field operations, improve our back-office operations and enhance our customer service capabilities. Although business

29

transformation performance was not a specific performance measure in 2010 or 2011, performance with regard to the business transformation project was included among the individual performance goals for Mr. Sterba and other NEOs. In light of the anticipated start up of enterprise resource planning (ERP) systems associated with Phase I of the project, encompassing such fundamental areas as human resources, finance and supply chain/procurement management activities, we determined that the inclusion of a business transformation performance measure is appropriate. The measure was weighted at 15 percent of the target Corporate Multiplier in order to provide a meaningful incentive for management to focus on efforts to successfully implement a key component of the project. The new business systems associated with Phase I of our business transformation project became operational on August 1, 2012.

Performance with regard to this measure was based on the judgment of the compensation committee as to how successful we were in completing our financial statements using a new ERP in the third quarter of 2012 and other measures of performance in ERP implementation. The percentage allocated to the Corporate Multiplier was determined at the discretion of the compensation committee after a review and discussion of an analysis compiled by an independent third-party quality assurance consultant and a discussion with Mr. Sterba and other senior executives.

Threshold (7.5% to be Included in Corporate Multiplier)	Target (15.0% to be Included in Corporate Multiplier)	Maximum (22.5% to be Included in Corporate Multiplier)
50%	100%	150%

Environmental Compliance (7.5 percent of target Corporate Multiplier)

This measure was based on the number of NOVs that we received or for which we are responsible. An NOV is a formal notification from a governmental agency, local health department or other regulatory agency that a water or wastewater system exceeded an acceptable limit (for example, a drinking water standard or air permit limit), failed to perform required monitoring, failed to record the required documentation or failed to meet another Federal, state, or local requirement. The NOVs for our market-based operations, where we operate but do not own the water or wastewater systems, are considered our responsibility unless it can be shown that (1) the NOV was outside the scope of the contract and (2) we formally notified the owner of the system in writing of the need for changes or improvements in order to maintain compliance, but the owner did not approve the changes or improvements. For 2012, the NOV target was 17, which was established based upon our goal to outperform the U.S. EPA published industry averages and our goal of leading the water industry in environmental compliance. We use this measure because we are committed to protecting the environment and to maintaining our consistent history of materially complying with, and in many cases surpassing, minimum standards required by applicable laws and regulations. We use aggressive NOV targets as part of a comprehensive plan to improve performance in this area.

21 NOVs	17 NOVs	11 NOVs

Safety Performance (7.5 percent of target Corporate Multiplier)

Safety performance was determined by reference to the total Occupational Safety and Health Administration Recordable Incident Rate or “ORIR” for American Water. ORIR is a measure of injuries and illnesses requiring treatment beyond first aid for every 200,000 hours worked. For 2012, the threshold and target ORIR were meaningfully reduced from last year’s threshold and target of 4.4 and 3.75, respectively, because we want to continue the momentum toward becoming an industry leader with respect to the safety and well-being of our

30

workforce. The benefits of improved safety are tangible, from the standpoint of the welfare of our employees as well as increased efficiency due to fewer lost workdays. However, at the recommendation of Mr. Sterba, the compensation committee exercised negative discretion to eliminate any award with respect to this measure due to two on-the-job employee fatalities.

3.75 ORIR	3.35 ORIR	3.15 ORIR

Service Quality (7.5 percent of target Corporate Multiplier)

This measure was designed to address overall service quality provided to our customers through our Service Quality Survey, which is conducted throughout the year for customers whose request for service resulted in completion of a service order by our field service representatives, and contains the following question: “Overall, how satisfied were you with the outcome of your service contact?” The question contains a five-point response scale based on the following categories: Extremely Satisfied, Very Satisfied, Somewhat Satisfied, Somewhat Dissatisfied, and Very Dissatisfied. The target for 2012 continued to be 85 percent of survey responses in the top two categories. Comparable industry averages are not available for this service level measure; however, advice from our professional market survey firm indicates that responses in the top two categories (Extremely Satisfied and Very Satisfied) are indicative of satisfaction levels associated with brand/product/service loyalty and advocacy, and an 85 percent or higher target would be considered “aggressive.”

Customer Satisfaction (7.5 percent of target Corporate Multiplier)

This measure was designed to address overall customer satisfaction through an annual survey, which is conducted throughout the year for customers having had recent contact with one of our customer service or field service representatives, and that contains the following question (modified to identify the applicable American Water subsidiary): “Overall, how satisfied have you been with American Water in general during the past twelve months?” The question has a five-point response scale based on the following categories: Extremely Satisfied, Very Satisfied, Somewhat Satisfied, Somewhat Dissatisfied, and Very Dissatisfied. Responses in the top three categories are indicative of overall customer satisfaction levels, and the target for 2012 continued to be 90 percent of survey responses in the top three categories. In addition, the quality of our service and issues raised by customers is a principal focus of state public utility commissions in evaluating a rate case.

Corporate Multiplier Table

Based upon our performance with regard to the financial and non-financial performance measures, the board approved the Corporate Multiplier of 130.6 percent. The Corporate Multiplier was determined as follows:

Performance Measure	Percentage Amount at Target for Inclusion in the Corporate Multiplier			Target	Actual Performance	Percentage Amount Included in Calculation of Corporate Multiplier Based on Actual Performance
EPS(1)		55.0	%	$1.92	$2.09		82.5	%
Business Transformation Performance		15.0	%	Discretionary Award	N/A		16.5	%
Environmental Compliance		7.5	%	17 NOVs	7 NOVs		11.3	%
Safety Performance(2)		7.5	%	3.35 ORIR	2.95 ORIR		0.0	%
Service Quality		7.5	%	85% of Surveyed Customers	89% of Surveyed Customers		10.5	%
Customer Satisfaction		7.5	%	90% of Surveyed Customers	93% of Surveyed Customers		9.8	%
					TOTAL		130.6	%(3)

(1) As adjusted to eliminate the impact of (a) the sale of certain subsidiaries and (b) costs associated with organizational streamlining.

(2) In light of two employee fatalities on the job, the Safety Performance percentage amount was reduced to zero at the recommendation of Mr. Sterba.

(3) The Corporate Multiplier of 130.6% was adjusted, for purposes of awards to NEOs, to 129.4% due to the allocation of $200,000 to creation of a special awards pool for non-executive officers.

Determination of Individual AIP Awards for NEOs

The target amount of individual awards was computed based on a percentage of base salary. Mr. Bigelow’s target award as a percentage of salary increased by five percent as a result of his promotion to Senior Vice President of Business Services. All other NEO target awards as a percentage of salary were unchanged from 2011.

The following table indicates the percentage of salary used to determine the target AIP award for each NEO:

Name	Percentage of Salary
Jeffry E. Sterba		100	%
Ellen C. Wolf		60	%
Walter J. Lynch		70	%
Kellye L. Walker		55	%
John R. Bigelow		50	%

The actual awards paid to each NEO, other than Mr. Sterba, were recommended by Mr. Sterba and, after review, approved by the compensation committee, based on the application of the Corporate Multiplier and on each NEO’s achievement against individual performance goals that we established at the beginning of 2012. The compensation committee recommended to the board the actual award to be paid to Mr. Sterba, based on its assessment of his performance with respect to each of his individual performance goals and application of the Corporate Multiplier.

32

The individual performance goals for each NEO were grouped into several performance categories that aligned to corporate performance expectations. In addition, within each category were a number of individual goals reflective of each NEO’s unique areas of responsibility.

Mr. Sterba:

The board evaluated Mr. Sterba’s 2012 performance based generally upon corporate performance and achievements compared to the targets contained in the Corporate Multiplier. These expectations focused on advancements in the Company’s strategic goals, including customer focus, operational excellence, employer of choice, environmental sustainability and targeted regulatory and public policies.

The board, without assigning a specific score for each or all of the strategic goals, assessed Mr. Sterba’s performance as “exceeding expectations” and awarded him an AIP payment of $970,500.

Other NEOs:

The other named executive officers also were subject to individual performance goals grouped into several categories. However, in making his recommendations to the board, Mr. Sterba expressed the view that, absent a marked departure from expected performance, the awards to the other NEOs should, generally, reflect the target award times the Corporate Multiplier. Mr. Sterba’s recommendation was based on his belief that the NEOs should assume principal responsibility for, and their awards generally should be based on, corporate performance, except with respect to executives who lead a profit center, such as Mr. Lynch (described below). Mr. Sterba advised the compensation committee that there were no factors of a magnitude that would cause him to recommend an adjustment for any of the other NEOs based on his or her individual performance. Therefore, Mr. Sterba recommended that each of the other NEOs receive an award equal to the Corporate Multiplier times the executive’s target award. The compensation committee accepted Mr. Sterba’s recommendation.

Mr. Lynch’s award was structured so that 50% was based on achievement of the executive team and 50% was based on performance of the regulated operations profit center. The performance of regulated operations was funded based upon net income, safety, NOVs, customer satisfaction and service quality. The performance of regulated operations resulted in achievement equal to 130.6% of target performance. After applying the same adjustment as was applied to the Corporate Multiplier, as described in footnote 3 to the Corporate Multiplier Table above, the percentage of target performance was reduced to 129.4%.

We have set forth the awards paid to our NEOs under the Non-Equity Incentive Plan Compensation column of the 2012 Summary Compensation Table.

Long-Term Incentive Plan

Our LTIP for 2012 included stock option grants and PSUs. As described in more detail below, the PSUs are awarded contingently, and the extent to which they are earned and the underlying shares of our common stock are distributed will be based on our achievement, over a three-year period, against three performance measures.

We based the target value of LTIP awards on a percentage of the NEOs salary. The percentage of salary on which the LTIP targets are based, and the total dollar values of the target LTIP award for NEOs were as follows:

Name	LTIP Target Award as Percentage of Salary			Value of LTIP Target Award
Jeffry E. Sterba		250	%	$	1,875,000
Ellen C. Wolf		130	%	$	624,000
Walter J. Lynch		145	%	$	710,500
Kellye L. Walker		110	%	$	412,500
John R. Bigelow		75	%	$	223,125

33

The compensation committee applied 40 percent of a NEOs LTIP target award to stock options and 60 percent to PSUs. We bifurcated long-term compensation in this manner because we believe it provides an appropriate balance between two related but discrete goals. Stock options are designed to align the executive officer’s interests with stockholder interests, since the intrinsic value of stock options is a function of the appreciation of our stock price. As explained in more detail below, the PSUs are designed to encourage long-term performance both from the standpoint of favorable stock performance in relation to the other 69 companies in the Comparator Group, and from the standpoint of specific company-wide performance measures. We chose to provide the larger percentage weighting for PSUs because we believe the greater emphasis should be on out-performing similarly situated companies and on the satisfaction of long-term operational goals.

In determining the number of shares underlying stock option grants, we used the $6.11 and $6.14 grant date fair value of the options, calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, which we refer to below as ASC 718. Based on the applicable grant date fair value, the number of shares underlying stock options was calculated as follows:

Name	LTIP Target Award Allocated to Stock Options		Number of Shares Underlying Stock Options
Jeffry E. Sterba	$	750,000		122,582
Ellen C. Wolf	$	249,600		40,851
Walter J. Lynch	$	284,200		46,514
Kellye L. Walker	$	165,000		27,005
John R. Bigelow	$	89,250		14,607

We based the number of shares underlying the PSUs granted to each of our NEOs on the LTIP Target Award allocated to PSUs, which, for each NEO, is shown in the table below:

Name	LTIP Target Award Allocated to PSUs
Jeffry E. Sterba	$	1,125,000
Ellen C. Wolf	$	374,400
Walter J. Lynch	$	426,300
Kellye L. Walker	$	247,500
John R. Bigelow	$	133,875

We allocated the LTIP target award among the three separate measures shown on the following table, which are discussed below:

Performance Measure	Weighting at Target
Total Stockholder Return		50	%
Operational Efficiency Improvement		25	%
Compounded EPS growth		25	%
Total		100%

34

The actual percentages of total PSUs granted to the NEOs with respect to the three performance measures differed from the percentage allocation of the target award. The grant date fair value of a PSU related to the total stockholder return performance measure was somewhat higher ($41.96 and $42.96) than the grant date fair value of a PSU related to the other two performance measures ($34.12 and $34.35). Therefore, the percentage of PSUs granted with respect to each performance measure was as follows:

Performance Measure	Percentage of PSUs Granted
Total Stockholder Return		44.8	%
Operational Efficiency Improvement		27.6	%
Compounded EPS Growth		27.6	%
Total		100.0	%

The total number of PSUs granted to each of the NEOs is shown in the following table:

Name	Number of PSUs Granted
Jeffry E. Sterba		29,773
Ellen C. Wolf		9,948
Walter J. Lynch		11,327
Kellye L. Walker		6,576
John R. Bigelow		3,557

The following is a description of the three performance measures related to the PSUs.

Total Stockholder Return

This measure is based on the comparative American Water total stockholder return, which we refer to as “TSR,” relative to the total stockholder return performance of the companies in the Comparator Group, in each case subject to a dividend adjustment factor, during the three-year performance period from January 1, 2012 through December 31, 2014. Specifically, we will compare (i) the percentage increase in the average daily closing stock price for our common stock for the 20 trading days before the end of the performance period, assuming reinvestment of dividends during the performance period, over the average daily closing stock of our common stock for the 20 days before the beginning of the performance period to (ii) the percentage increase over the same periods in the average closing price of each of the companies in the Comparator Group, in each case assuming reinvestment of dividends during the performance period.

We selected TSR as the principal performance measure to encourage performance that not only increases stockholder value but increases it to an extent that compares favorably relative to the Comparator Group.

The following table shows the actual number of PSUs to be earned, as a percentage of the target PSU award (equivalent to the number of PSUs granted) based upon American Water’s TSR relative to the 69 companies in the Comparator Group:

American Water TSR Ranking*	Percent of Target Award PSUs Earned*
75% or more (maximum)		78.4	%
50% (target)		44.8	%
25% (threshold)		11.2	%
Less than 25%		0	%

* If the TSR ranking is between 25% and 50%, or between 50% and 75%, the percent of target award PSUs earned will be adjusted proportionately.

35

Operational Efficiency Improvement

This measure is calculated based on the ratio of total operation and maintenance expense to total operating revenues for our regulated operations; the ratio is reduced as operational efficiency improves. The calculation of this measure will be based on the average of the ratio for each of 2012, 2013 and 2014. We used this measure because we want to focus management on improving our overall cost structure and improving our return on equity.

The following table shows the actual number of PSUs to be earned, as a percentage of the target award, based on American Water’s operational efficiency improvement.

	Percent of Target Award PSUs Earned
39.2% or less (maximum)		48.3	%
41.2% (target)		27.6	%
43.2% (threshold)		6.9	%
More than 43.2%		0	%

* If the operational efficiency improvement is between 43.2% and 41.2% or 41.2% and 39.2%, percent of the target award PSUs earned will be proportionately adjusted.

Compounded EPS Growth

This measure is based on the growth of our EPS, as reported in our audited 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, all as determined in accordance with financial accounting standards, compounded annually over the three year period from January 1, 2012 through December 31, 2014, over the adjusted EPS of $1.78 for the year ended December 31, 2011. We selected this measure for the same reasons as set forth with respect to EPS under the annual incentive plan description above, although we are using the measure in connection with the LTIP to encourage a long-term focus on earnings growth.

The following table shows the actual number of PSUs to be earned, as a percentage of the target award, based on our compounded EPS growth:

Compounded EPS Growth*	Percent of Target Award PSUs Earned
10.0% (maximum)		48.3	%
7.0% (target)		27.6	%
5.0% (threshold)		6.9	%
Less than 5.0%		0	%

* If the increase in compounded EPS growth is between 5.0% and 7.0% or 7.0% and 10.0%, the percent of target award PSUs earned will be proportionately adjusted.

Vesting of Options and PSUs

The options granted to our NEOs terminate on December 31, 2018 (if not previously exercised or forfeited), and vest in equal increments on January 1, 2013, 2014 and 2015. Similarly, a NEO’s right to PSUs earned at the end of the performance period vests in equal increments on January 1, 2013, 2014 and 2015. We believe that the vesting terms provide our executive officers a meaningful incentive for continued employment.

36

Performance Vesting of PSUs Granted in 2010

In 2010, we granted PSUs to our executives and other employees for which the performance period ended in 2012. The number of PSUs earned was based on our performance with respect to four separate measures shown on the following table and discussed below:

Performance Measure	Weighting at Target
Total Stockholder Return		63.84	%
Operational Efficiency Improvement		18.08	%
Compounded EPS growth		9.04	%
Increase in Population Served		9.04	%
Total		100.00	%

Total Stockholder Return. This measure is based on the comparative American Water TSR, relative to the total stockholder return performance of the 74 companies in the Comparator Group during the applicable performance period. The comparative TSR was computed in the same manner as the Comparative TSR is computed with respect to the PSUs granted in 2010, except that the performance period for the PSUs granted in 2012 extended from January 1, 2010 through December 31, 2012.

Our TSR during the performance period was greater than 97% of the other companies in the Dow Jones U.S. Utilities Index. As a result, 175% of the PSUs granted with respect to this measure were performance vested, as indicated in the following table:

Name	Number of PSUs Granted		Number of PSUs Performance Vested
Jeffry E. Sterba*		8,081		14,140
Ellen C. Wolf		9,846		17,229
Walter J. Lynch		11,000		19,249
Kellye L. Walker		5,901		10,326
John R. Bigelow		3,432		6,006

* Mr. Sterba joined us in August 2010 and received a prorated portion of the 2010 grants

Operational Efficiency Improvement. This measure was calculated in the same manner as described above for PSUs granted in 2012, but was calculated with respect to each of 2010, 2011 and 2012.

The average of the ratio of total operation and maintenance expense to total operating revenues for our regulated operations in 2010, 2011 and 2012 was 48.1%. As a result, a number of shares equal to 175% of the PSUs granted with respect to this measure were issuable based upon performance vesting, as indicated in the following table:

Name	Number of PSUs Granted		Number of PSUs Performance Vested		Percentage of  PSUs Performance Vested
Jeffry E. Sterba*		2,262		3,958		175	%
Ellen C. Wolf		2,797		4,894		175	%
Walter J. Lynch		3,127		5,472		175	%
Kellye L. Walker		1,677		2,933		175	%
John R. Bigelow		975		1,706		175	%

* Mr. Sterba joined us in August 2010 and received a prorated portion of the 2010 grants

Compounded EPS Growth. This measure was based on the growth of our EPS, as reported in our audited financial statements, compounded annually over the three year period from January 1, 2010 through December 31, 2012, over the adjusted EPS of $1.25 for the year ended December 31, 2009.

37

Our Compounded EPS Growth during the performance period was 17.1%. As a result, a number of shares equal to 175% of the PSUs granted with respect to this measure were issuable based upon performance vesting, as indicated in the following table:

Name	Number of PSUs Granted		Number of PSUs Performance Vested
Jeffry E. Sterba*		1,131		1,979
Ellen C. Wolf		1,399		2,448
Walter J. Lynch		1,563		2,735
Kellye L. Walker		838		1,467
John R. Bigelow		488		854

* Mr. Sterba joined us in August 2010 and received a prorated portion of the 2010 grants

Increase in Population Served. This measure was based upon the growth in population served by our regulated and market-based operations during the period from January 1, 2010 through December 31, 2012. We initially selected this measure because we believed it to be an important indicator (along with rate increases) of revenues from our regulated and market-based businesses. However, we discontinued the use of this performance measure in 2010 because we subsequently concluded that an increase in population served is not a reliable indicator of revenue increases. There was no payout related to this measure.

The performance vested PSUs were paid out in shares of our stock upon certification by the compensation committee on January 23, 2013.

Perquisites

We provide limited perquisites to our executive officers, principally consisting of executive physicals. Because the efforts of our leadership team are important to our success, we believe it is important to provide an executive physical benefit. In keeping with our wellness culture, we believe providing periodic physicals for executives can help them to detect medical conditions before they become serious.

NEW EMPLOYMENT LETTER AGREEMENT WITH JEFFRY E. STERBA

On March 26, 2012, we entered into a new employment letter agreement with Mr. Sterba, which we refer to below as the “2012 Employment Agreement”. See “Executive Compensation – Employment Agreements – Jeffry Sterba” and “Severance Terms in Jeffry E. Sterba’s Employment Agreement” for further information.

STOCKHOLDER ADVISORY VOTE ON EXECUTIVE COMPENSATION

At our 2012 annual meeting, the stockholders approved, on a non-binding, advisory basis, the compensation paid to our NEOs, as disclosed under the compensation disclosure rules of the Securities and Exchange Commission, including the compensation discussion and analysis, the compensation tables and any related materials disclosed in the proxy statement for the 2012 annual meeting. The stockholder vote in favor of NEO compensation totaled approximately 98.7 percent of all votes cast, including abstentions. We considered the results of the advisory vote and determined that, in light of the strong favorable vote of our stockholders, no specific action need be taken in response to the vote.

STOCK OPTION GRANT PRACTICES

Our compensation committee makes annual stock option grants to employees, including executive officers, in February of each year. The exercise price per share for options is at least equal to the last reported sale price of our common stock on the date of grant. Moreover, we will not reprice any options without seeking stockholder approval. We believe that our stock option grant practices are appropriate and effectively address any concerns regarding “timing” of grants in anticipation of material events.

38

EXECUTIVE STOCK RETENTION REQUIREMENTS

In order to closely align the interests of our executives with those of our stockholders, our board of directors has adopted the Stock Retention Program for Executives, which we refer to below as the “Program.” Under the Program, our executive officers are required to retain 50 percent of the after-tax value realized on each equity grant until termination of employment or a change in control, whichever occurs earlier. For this purpose, the after-tax value realized is determined at the time the executive recognizes taxable income with respect to the equity grant.

For purposes of determining the after-tax value realized on an equity grant, we assume that all executives will be subject to taxes (federal, state, and local) at a total effective tax rate of 40 percent, irrespective of the executive’s actual total effective tax rate and regardless of how any applicable tax liability is satisfied. As a result, our executive officers are required to retain 30% of the gross value realized on each equity grant. Examples of the application of Program requirements to stock options and PSUs are described below.

Stock Options

Assume an executive was granted a stock option to purchase 2,000 shares at $30.00 per share on February 15, 2012, and on February 15, 2013, the date all shares underlying the option vested, the market price per share of our common stock is $40.00 per share. If the executive exercises all of the options on that date, the value realized by the executive will be $20,000 (computed by subtracting the $30.00 per share exercise price from the $40.00 per share market price, and multiplying the $10.00 per share remainder by 2,000, the number of shares underlying the option). After assuming the 40 percent tax rate, the executive’s after-tax value realized would be $12,000. Accordingly, the executive would be required to retain shares having a value of $6,000 (50 percent of $12,000), or 150 shares.

PSUs

Assume an executive was awarded 600 PSUs on February 15, 2011, and on December 31, 2013, the date as of which the number of PSUs is adjusted to reflect the applicable three-year performance, the number of shares underlying the executive’s PSUs was increased to 700. If the stock price is $40.00 per share on December 31, 2013, the value realized by the executive would be $28,000. After assuming the 40 percent tax rate, the executive’s after-tax value realized would be $16,800. Accordingly, the executive would be required to retain shares having a value of $8,400 (50 percent of $16,800), or 420 shares.

ONGOING AND POST-EMPLOYMENT ARRANGEMENTS AND PLAN PROVISIONS

We have several plans and arrangements that enable our NEOs to accrue retirement benefits as they continue to work for us, provide severance benefits upon certain types of termination of employment, or provide other forms of deferred compensation. Most of these plans and agreements have been adopted within the past few years, although some plans, particularly our defined benefit plans that are no longer available to new employees, were adopted some time ago. Not all plans apply to each NEO, as indicated in the discussion below.

Savings Plan for Employees of American Water Works, Inc. and Designated Subsidiaries—the “Savings Plan”

This is a tax qualified defined contribution plan available to employees of American Water, including our NEOs, and certain subsidiaries. Each of our currently employed NEOs participates in the Savings Plan. Under the Savings Plan, an employee may contribute, subject to Internal Revenue Code limitations, 50 percent of his or her base salary up to a maximum contribution of $17,000, plus, for eligible participants, $5,500 for catch-up contributions. For any NEO participant hired before January 1, 2006, who continues to be employed by us (Messrs. Lynch and Bigelow), the matching contribution formula is: 50 percent of a participant’s base salary

39

contributions for the year, up to a maximum of 5 percent of the participant’s base salary. For NEO participants hired after January 1, 2006, the matching contribution formula is: (a) 100 percent for every dollar contributed up to the first 3 percent of the participant’s base salary, and (b) 50 percent on the next 2 percent of the participant’s base salary. In addition, for NEO participants hired after January 1, 2006, we make additional annual contributions equal to the sum of 5.25 percent of the participant’s base salary, subject to Internal Revenue Code limitations. We provide more generous contributions to participants hired after January 1, 2006, because they are ineligible to participate in the defined benefit pension plans described below.

Amounts credited to an employee’s account may be invested among a number of funds, and the value of a participant’s account will be increased or decreased to reflect the performance of selected investments.

American Water Works Company, Inc. Pension Plan—the “AWWPP”; American Water Works Company, Inc. Executive Retirement Plan—the “ERP”

The AWWPP is a tax-qualified defined benefit pension plan available to eligible employees who commenced employment with us prior to January 1, 2006. The AWWPP provides an annual retirement benefit based on an employee’s earnings and years of service. For executives hired prior to July 1, 2001, a grandfathered benefit is provided. Messrs. Lynch and Bigelow participate in the AWWPP. Ms. Wolf, who we employed from 1999 to 2003 and re-employed beginning in 2006, has an accrued benefit under the AWWPP based on her earlier term of service, but will not accrue additional benefits under the AWWPP.

The ERP is a nonqualified defined benefit pension plan that provides pension benefits under the same formula as the AWWPP, but without the pay and benefit limitations that are applicable to the AWWPP under the Internal Revenue Code. Messrs. Lynch and Bigelow participate in the ERP. We closed the AWWPP and the ERP to new employees on December 31, 2005 and replaced those plans with defined contribution plans. This action was taken for a number of reasons, including to enable us to predict fixed costs for retirement benefits on an ongoing basis. In contrast, we are subject to variable costs in connection with our defined benefit plans based on the performance of the plans’ investment portfolios.

See “Executive Compensation—2012 Pension Benefits” for further information regarding the AWWPP and the ERP.

Nonqualified Savings and Deferred Compensation Plan for Employees of American Water Works Company, Inc. and its Designated Subsidiaries—the “Deferred Compensation Plan”

This plan is a nonqualified deferred compensation plan that enables participants to defer salary and annual incentive plan awards and provides benefits to executive officers and other highly paid employees in excess of the maximum benefits that may be provided under the Savings Plan as a result of limits imposed by the Internal Revenue Code. We refer to compensation in excess of those limits as “excess compensation.” All of the currently employed NEOs participate in the Deferred Compensation Plan.

Generally, under the Deferred Compensation Plan, an executive may elect to defer up to 20 percent of salary and up to 100 percent of the award paid under the AIP. We provide matching contributions that differ depending on whether the executive was hired or rehired by us on or after January 1, 2006. For NEOs hired or rehired after January 1, 2006 (Mr. Sterba, Ms. Wolf and Ms. Walker), we provide the matching contribution we would have made for the executive under the Savings Plan with respect to the executive’s excess compensation if the excess compensation had been taken into account under the Savings Plan. In addition, we make a defined contribution for the account of each of these executives generally equal to 5.25 percent of the sum of base salary that constitutes excess compensation and the award payable under the AIP for the relevant plan year. For executives hired prior to January 1, 2006, and continuously employed by us (Messrs. Lynch and Bigelow), our matching contribution is equal to 50 percent of salary deferrals up to a maximum of five percent of salary; the matching contributions are more limited for these executives due to their eligibility under our defined benefit pension plan.

40

Each participant may allocate amounts credited to his or her account among several notional investments, and the value of the account will be increased or decreased to reflect deemed returns under the selected notional investments. The participant may elect to receive payment of deferred amounts in a lump sum or in annual installments, on or beginning at separation from service or a specified distribution date. See “Executive Compensation—2012 Nonqualified Deferred Compensation” for additional information.

Executive Severance Policy

Under our executive severance policy, adopted in 2008, we provide severance benefits to our NEOs. Our policy is designed to provide a clear statement of the rights of our executive officers if they are involuntarily terminated without cause. Among other things, the policy calls for 12 months of salary continuation for the NEOs, and a pro rata AIP award for the year in which the termination date occurs to the extent such payment is provided for under the terms of the applicable AIP. Mr. Sterba’s 2012 Employment Agreement provides that he will be entitled to 18 months of salary continuation. See “Executive Compensation—Potential Payments on Termination or Change in Control” for further information.

American Water Works Company, Inc. Nonqualified Employee Stock Purchase Plan—the “ESPP”

Under the ESPP, eligible employees, including our NEOs, are provided an opportunity to purchase our common stock at a discount of ten percent from the lower of the prevailing market price on the first day and last day of each three-month purchase period. Purchases generally are limited to $25,000 per year. We believe that, in addition to the benefit employees realize from the discount, our stockholders will benefit because the ESPP helps to more closely align the interests of our employees and our stockholders.

Change in Control Provisions in Equity Plans

Most of our compensation plans and policies do not contain change in control provisions affecting compensation of our NEOs. However, our equity awards generally vest upon a change in control of American Water. In addition, certain of our contributions to the Deferred Compensation Plan will vest upon a change in control. See “Executive Compensation—Potential Payments on Termination or Change in Control” for further information.

Recovery of Incentive Compensation

In 2010, we instituted a policy governing the recovery of incentive compensation in the event of a material restatement of our financial results under specified circumstances. As a result of the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which imposes an executive compensation “clawback” requirement on public companies, and the related NYSE listing standards expected to be adopted in 2013, we expect to amend the policy to comply with these executive compensation recovery requirements.

TAX CONSIDERATIONS

Section 162(m) of the Internal Revenue Code limits to $1 million the deductibility for federal income tax purposes of annual compensation paid by a publicly held corporation to its chief executive officer and other NEOs, unless certain conditions are met. Because we wish to maintain flexibility in structuring our compensation to address our corporate goals, the board of directors has not adopted a policy regarding the deductibility of compensation. However, the board will review from time to time the advisability of structuring our compensation programs to satisfy the deductibility requirements of Section 162(m).

COMPENSATION COMMITTEE REPORT

The compensation committee has reviewed and discussed the foregoing Compensation Discussion and Analysis with management. Based on this review and discussion, the compensation committee has recommended to the full board of directors that the Compensation Discussion and Analysis be included in this proxy statement.

Risk Considerations Related to Compensation Policies and Practices

The board and compensation committee have each assessed potential risks related to our compensation policies and practices and have concluded that they are not reasonably likely to have a material adverse effect on American Water. In considering risks related to our compensation policies and practices, the board and compensation committee noted that less than 30 percent of our employees participate in any form of variable compensation and 82 percent of the participating employees have a target award that is not greater than 15 percent of base pay. Therefore, the analysis focused on our executive compensation, because a significant portion of compensation for our senior managers is performance-based. The board and compensation committee considered the following mitigating factors with respect to executive compensation:

• Factors mitigating risks relating to short-term incentives—Short-term incentives, available through the AIP, comprised only a limited portion of total compensation (in the case of Mr. Sterba, his 2012 AIP target award was approximately 22 percent of direct compensation); company-wide and individual targets were dispersed among a variety of financial and non-financial goals; maximum awards are capped at 200 percent of target; and the compensation committee has broad discretion in determining the amount of AIP awards.

• Factors mitigating risks related to long-term incentives—The three year vesting and performance periods applicable to our long-term incentive compensation require a long-term executive focus; annual grants of long-term awards result in overlapping vesting and performance periods, which reduces risks that executives will focus only on one performance or vesting period; executives are discouraged from seeking short-term increases in stock prices in connection with stock option exercises because stock options comprise only a portion of our equity compensation and the rest of our equity compensation is based on long-term performance; and our equity compensation is subject to our Stock Retention Program, described above under “Executive Stock Retention Requirements.”

Employment Agreements

We have employment agreements with Mr. Sterba and Mses. Walker and Wolf, which are summarized below. Portions of the employment agreements, if any, addressing terms upon retirement or other termination of employment are described below under “Potential Payments on Termination or Change in Control.”

Jeffry E. Sterba. Prior to March 26, 2012, some terms of Mr. Sterba’s employment were subject to an employment agreement with us dated August 15, 2010. The agreement provided for a target payout under the AIP of 100 percent of his base salary and granted him options to purchase 25,000 shares of our common stock at an exercise price of $22.66 per share, which were fully vested August 15, 2012 and expire on August 15, 2017. The agreement also provided for Mr. Sterba’s pro-rated participation in our long-term incentive plan with a target payment equal to 200 percent of his base salary. In addition, Mr. Sterba participated in our deferred compensation, retirement and benefit plans.

On March 26, 2012, we entered into a new employment agreement ( the “2012 Employment Agreement”) with Mr. Sterba, which supersedes the employment agreement described above.

Under the 2012 Employment Agreement, Mr. Sterba will continue to serve as the Company’s President and Chief Executive Officer, and as a member of our board of directors (assuming he continues to be elected by the stockholders). The Agreement contains the following compensatory provisions:

• Mr. Sterba’s annual base salary was increased to $750,000, effective on March 19, 2012.

• Mr. Sterba’s target award under the Company’s annual incentive plan will continue to be 100% of his annual base salary.

• For the years 2012, 2013 and 2014, Mr. Sterba’a target payout under the Company’s Long-Term Incentive Plan (“LTIP”) will be increased to 250% of his annual base salary. Mr. Sterba’s 2012 LTIP grants will be increased to reflect the increased target payout.

• Mr. Sterba’s performance stock unit (“PSU”) grants and option grants under the LTIP in 2012, 2013 and 2014 are or will be subject to the following terms:

• Grants made in 2012 will time-vest in three equal installments on January 1, 2013, 2014 and 2015.

• Grants made in 2013 will time-vest in two equal installments on January 1, 2014 and 2015.

• Grants made in 2014 will fully time-vest on January 1, 2015.

• The time-vesting of Mr. Sterba’a options and PSUs generally are subject to his continued employment by the Company, subject to severance provisions described below under “Potential Payments on Termination or Change in Control—Severance Terms in Jeffry E. Sterba’s Employment Agreement.”

• Each PSU grant also would be subject to performance-vesting criteria based upon our performance during the applicable three year performance period, and payouts, if any, to Mr. Sterba under the PSUs would be made between January 1 and March 10 of the year following the last year of the performance period.

• If vesting terms of the LTIP and related grants are more favorable than those described above, the terms of the LTIP and related grants will prevail.

45

The Agreement also provides for Mr. Sterba’a participation in our health, life, disability and liability insurance, 401(k) and deferred compensation plans.

Ellen C. Wolf. Ms. Wolf entered into an employment letter agreement with American Water dated December 29, 2005, and restated as of February 15, 2008. Under the agreement, Ms. Wolf serves as our Senior Vice President and Chief Financial Officer. The agreement provided for Ms. Wolf’s annual base salary of $463,500 (which we subsequently increased to $480,000) and her participation in the annual incentive plan with a target payout equal to 50 percent of her base salary (which we subsequently increased to 60 percent of her base salary). The agreement also provided for Ms. Wolf’s participation in American Water’s 2007 Omnibus Equity Compensation Plan with an equity target award of 115 percent of her base salary (which we subsequently increased to 130 percent of her base salary). In addition, Ms. Wolf is eligible to participate in our deferred compensation, retirement and benefit plans.

Ms. Wolf entered into an Agreement and General Release with the Company, dated March 25, 2013, and amended on March 27, 2013, under which she has agreed to facilitate a transition during the period from April 2, 2013 until May 1, 2013 (the “Transition Period”). At the conclusion of the Transition Period, Ms. Wolf will retire. During the Transition Period, she will be considered a general executive employee of the Company and continue to receive the same compensation and benefits as she received while serving as the Company’s Senior Vice President and Chief Financial Officer. In addition, from the date of her retirement through August 30, 2013 (the “Consult Period”), Ms. Wolf will provide up to 100 hours of service, without compensation, to answer questions and provide assistance on matters for which she has knowledge or relevant information. Ms. Wolf is not required to be physically present in the Company’s office during the Consult Period without her consent. If the Company requests that she perform any work during this period or be physically present in the office during the Consult Period in excess of the 100 hours of service described above, she will be compensated at the rate of approximately $370 per hour.

In return for the performance of her obligations under the Agreement and General Release, options to purchase 43,423 shares of Company common stock granted to Ms. Wolf in 2011 and 2012 that otherwise would not have vested will fully vest and may be exercised within one year from her date of retirement. Ms. Wolf’s 12,476 performance stock units granted to her in 2011 and 9,948 performance stock units granted to her in 2012 also will become fully vested, and the number of shares underlying performance stock units ultimately to be delivered to Ms. Wolf with respect to such performance stock units otherwise will be determined in accordance with the terms of the relevant performance stock unit agreements. In addition, Ms. Wolf will be eligible to receive an Annual Incentive Plan award, prorated for the period from January 1, 2013 to April 30, 2013, if such an award is paid out to eligible participants. Ms. Wolf’s benefits under the Company’s pension plan, Nonqualified Savings and Deferred Compensation Plan, and, except as otherwise noted above, Omnibus Equity Compensation Plan, are not affected by the Agreement and General Release.

In connection with her execution of the Agreement and General Release, Ms. Wolf agreed to specified confidentiality, two-year non-competition and non-solicitation provisions and provided a general release to the Company.

Kellye L. Walker. Ms. Walker entered into an employment letter agreement with us, dated December 21, 2009. Under the agreement, Ms. Walker initially served as our Senior Vice President, General Counsel and Secretary. The agreement provided for Ms. Walker’s annual base salary of $340,000 (which we subsequently increased to $375,000 in light of additional responsibilities she assumed upon her appointment as our Chief Administrative Officer, Senior Vice President, General Counsel and Secretary in September 2010), and her participation in the annual incentive plan with a target payout equal to 55 percent of her base salary. The agreement also provided for Ms. Walker’s participation in our long-term incentive plan with a target payout equal to 110 percent of her base salary. In addition, Ms. Walker is eligible to participate in our deferred compensation, retirement and benefit plans.

2012 Pension Benefits

American Water Works Company, Inc. Pension Plan

The American Water Works Company, Inc. Pension Plan, which we refer to as the “AWWPP,” is a qualified pension plan that provides for a pension benefit equal to 1.6% of final average pay multiplied by years of service. Final average pay is defined for purposes of the plan as the average sum of base pay plus annual incentive payout for the highest 60 months out of the final 120 months of employment. For executives hired prior to July 1, 2001, a grandfathered benefit is provided. Normal retirement is defined as age 65, and early retirement eligibility is satisfied when an employee’s age is at least 55 and the employee has attained a service requirement that varies based on whether the employee is in a grandfathered group and, if so, the location of such group. Benefits vest in the AWWPP upon completion of five years of service. All the named executive officers who participate in the plan are vested in their pension benefits. The normal form of payment is a single life annuity for single participants and a 50% joint and survivor annuity for married participants. The 50% joint and survivor annuity benefit amount is determined to be actuarially equivalent to the single life annuity amount. There is a reduction in benefits for early retirement for participants other than those who retire at age 62 or older with specified service levels, such as 20 years of service for someone who is age 62.

American Water Works Company, Inc. Executive Retirement Plan

The American Water Works Company, Inc. Executive Retirement Plan, which we refer to as the ERP, is a nonqualified defined benefit pension plan that provides benefits under the same formula as the AWWPP, but without the pay and benefit payment limitations that are applicable to the AWWPP under the Internal Revenue Code and including deferred compensation in calculating the final average pay. The ERP also provides a minimum benefit in accordance with provisions of former executive retirement plans that American Water sponsored, the American Water Works Company, Inc. Supplemental Executive Retirement Plan and Supplemental Retirement Plan, which we refer to as the SERP and SRP, respectively. Executives who were participants in this nonqualified pension plan are entitled to the greater of the benefits determined pursuant to the restoration formula under the ERP and the benefits determined pursuant to their respective prior nonqualified plan formulas. Mr. Bigelow participated in the former SRP. Mr. Lynch participates in the restoration provisions of the ERP. All the named executive officers who participate in a nonqualified plan are vested in their nonqualified pension benefits. Upon retirement, nonqualified plan benefits are payable as lump sums unless the participant has elected an alternate form of payment pursuant to the Internal Revenue Code regulations under Section 409A. Mr. Bigelow will receive his benefit as an annuity and Mr. Lynch will receive his benefits as a lump sum. Upon voluntary termination of employment prior to eligibility for early or normal retirement, nonqualified benefits are payable as deferred (to age 65) annuities or lump sum equivalents of such deferred annuities. All nonqualified plan lump sums are calculated as the present value of deferred or immediate single life annuities.

(1) Since Mr. Sterba and Ms. Walker were hired after 2005, they do not participate in our defined benefit plan.

(2) Ms. Wolf is entitled to receive a benefit from the AWWPP, attributable to her prior period of employment from May 24, 1999 through December 1, 2003. The benefit is payable in its normal form of a life annuity or

50

actuarially equivalent Joint and Survivor form beginning at age 65. Ms. Wolf may elect to retire early and commence reduced payments immediately provided her age plus credited service at retirement exceed 70. At the time that Ms. Wolf’s and Mr. Lynch’s age plus credited service exceed 70, they also become eligible for a subsidized early retirement benefit payable as an annuity in form elected under the provision of the plan of retirement benefit. Presently Ms. Wolf, Mr. Bigelow and Mr. Lynch are all eligible to receive a disability retirement benefit under this plan.

(3) Amounts shown reflect the present value of the accumulated benefit of each named executive officer as of December 31, 2012. All amounts for the pension plans were determined using the same interest and mortality assumptions as those used for financial reporting purposes. The following assumptions were used to calculate pension values at the following measurement dates: 2011 (for purposes of the column titled “Change in Pension Value and Nonqualified Deferred Compensation Earnings” in the “2012 Summary Compensation Table”)—discount rate of 5.02% and an assumed interest basis (assumed to be 5.02%), for calculating lump sums that reflects the change to Section 417 of the Internal Revenue Code made by the Pension Protection Act of 2006, including the phase-in for any lump-sum payments assumed to commence during 2011, and mortality based on the Society of Actuaries’ RP2000 sex distinct tables projected to 2018 with phase out and no collar adjustment for discounting annuity payments, and the Society of Actuaries’ RP 2000 unisex static table for calculating lump sums as prescribed by Section 417 of the Internal Revenue Code for 2011, and for 2012 (for purposes of the column titled “Change in Pension Value and Nonqualified Deferred Compensation Earnings” in the “2012 Summary Compensation Table” and for this table)—discount rate of 4.17% and an assumed interest basis for calculating lump sums (assumed to be 4.17%) that reflects the change to Section 417 of the Internal Revenue Code made by the Pension Protection Act of 2006, and mortality based on the Society of Actuaries’ RP2000 sex distinct tables projected to 2019 with phase out and no collar adjustment for discounting annuity payments, and the Society of Actuaries’ RP 2000 unisex static table for calculating lump sums as prescribed by Section 417 of the Internal Revenue Code for years after 2009.

For further information on American Water’s defined benefit pension plans, see “Potential Payments on Termination or Change in Control,” below.

2012 Nonqualified Deferred Compensation

All the named executive officers participate in the Nonqualified Savings and Deferred Compensation Plan for Employees of American Water Works Company, Inc. and its Designated Subsidiaries. For the named executive officers, the deferred compensation plan permits the deferral of up to 20% of base salary and up to 100% of bonus each year on a tax-favored basis. It also provides for annual matching contributions determined by the following formula for named executive officers hired on or after January 1, 2006 (Mr. Sterba and Mses. Walker and Wolf): (a) the sum of (i) 100% of a participant’s voluntary deferrals for the year, up to a maximum of 3% of the sum of the participant’s base salary and bonus and (ii) 50% of a participant’s voluntary deferrals for the year, up to a maximum of the next 2% of the sum of the participant’s base salary and bonus, less (b) the maximum amount of matching contributions that the participant is eligible to receive under the 401(k) plan for the year. For named executive officers hired before January 1, 2006 (Messrs. Lynch and Bigelow), the matching contribution formula is: (a) 50% of a participant’s base salary deferrals for the year, up to a maximum of 5% of the participant’s base salary, less (b) the maximum amount of matching contributions that the participant is eligible to receive under the 401(k) plan for the year. In addition, we make additional annual contributions for named executive officers hired on or after January 1, 2006, equal to the sum of (a) 5.25% of the participant’s base salary in excess of the dollar limitation in effect under Section 401(a)(17) of the Internal Revenue Code with respect to the year and (b) 5.25% of the participant’s bonus. Participants’ deferred compensation accounts are credited with returns in accordance with the deemed investment options elected by the participant. Participants are immediately vested in all contributions to the plan, except for the 5.25% annual contributions, excluding those made for Ms. Wolf, which vest at the earliest of (i) completion of five years of service, (ii) attainment of age 65, (iii) death, or (iv) a change in control. Participants may elect to receive their

51

account balances at any of the following times: (i) separation from service, (ii) a specified distribution date, (iii) the earlier of separation from service or a specified distribution date or (iv) the later of separation from service or a specified distribution date, and may elect any of the following forms for distribution of their accounts: (i) lump sum or (ii) annual installments paid over a period of between two and 10 years. None of the named executive officers had any withdrawals or distributions from the plan in 2012.

Potential Payments on Termination or Change in Control

This section describes the potential payments that would have been made to the named executive officers upon various types of terminations of employment or a change in control of American Water on December 31, 2012.

Executive Severance Policy. Our executive severance policy provides severance benefits to executives whose employment is involuntarily terminated by American Water for reasons other than cause. The determination of whether an executive’s employment is terminated for cause will be made at the sole discretion of the board of directors of American Water. Under the policy, eligible executives will receive 12 or, in the case of Mr. Sterba, 18, months of their base salary, in the form of base salary continuation. As noted below under “Severance Terms in Jeffry E. Sterba’s Employment Agreement,” at December 31, 2011, Mr. Sterba would be entitled to 18 months of base salary if he is terminated after August 15, 2013. Eligible executives are entitled to continued health, dental and vision coverage based on their years of service, in the amount of eight weeks of coverage for less than five years of service, 12 weeks of coverage for at least five years but less than 10 years of service and 16 weeks of coverage for 10 or more years of service. They are also entitled to life insurance coverage and continued participation in the employee assistance plan for the number of months of their severance benefits, as well as 12 months of outplacement services. In order to receive severance benefits under the executive severance policy, an executive must sign a release and waiver of any claims against American Water and agree to certain restrictive covenants. Severance benefits payable under the severance policy will be offset and reduced by any other severance benefits payable under any employment agreement or otherwise.

52

Severance Terms in Jeffry E. Sterba’s Employment Agreement. Under the 2012 Employment Agreement, in the event we terminate Mr. Sterba’s employment without “cause” (as defined in the 2012 Employment Agreement) he terminates employment with us for “good reason” (as defined in the 2012 Employment Agreement),

• Mr. Sterba will be entitled to receive 18 months base salary, payable in installments, and will continue to receive health, dental and vision coverage in accordance with our executive severance policy.

• Mr. Sterba will receive a prorated award under the AIP for the year during which he is terminated. He also will be entitled to the prorated AIP award in the event his employment terminates due to his death or disability.

• The options to purchase 25,000 shares previously granted to Mr. Sterba in August 2010 will become fully vested (and the option term will be extended to the earlier of two years from his termination or the end of the seven year term of the options).

• All PSUs and options granted to him in 2012, 2013 and 2014 will fully time-vest (and the term of the options will be extended to the earlier of two years from his termination or the end of the stated term of such options). Time-vesting also will be accelerated in the event of his death or disability. (Each PSU grant will remain subject to performance-vesting criteria based upon our performance during the applicable three year performance period).

To the extent the terms of the LTIP and related grants provide more favorable vesting provisions than those set forth above, the terms of the LTIP and related grants will control.

“Good reason” is defined as meaning any of the following events occurring without Mr. Sterba’s consent: Mr. Sterba ceases to be our Chief Executive Officer other than in connection with the appointment by the board of directors during 2014 or thereafter of a new Chief Executive Officer; Mr. Sterba ceases to be a member of the board of directors; any material breach by us of any of the terms and conditions of the 2012 Employment Agreement; Mr. Sterba is required to relocate his office to a location more than 50 miles from its current location in Voorhees, New Jersey; Mr. Sterba’s duties as Chief Executive Officer are diminished or altered in any way to his material detriment other than in connection with the appointment during 2014 or thereafter of a new Chief Executive Officer; or Mr. Sterba’s compensation or benefits are diminished or altered in any way to his material detriment.

Severance Terms in Ellen C. Wolf’s Employment Agreement. Ms. Wolf’s employment letter agreement provides that if we terminate Ms. Wolf’s employment other than for cause (as determined in our sole discretion), or if Ms. Wolf terminates her employment for “good reason” (as described below), she will be deemed to have fully vested in all her benefits under the 2007 Omnibus Equity Compensation Plan and the deferred compensation plan so long as such vesting is permitted by applicable law. “Good reason” is defined as (i) a diminishment in Ms. Wolf’s authority that is substantially and materially inconsistent with her position as Senior Vice President and Chief Financial Officer of a public company or (ii) the assignment to Ms. Wolf of duties that are substantially and materially inconsistent with her position as Senior Vice President and Chief Financial Officer of a public company.

Deferred Compensation Plans. Our deferred compensation plan for employees is described above under “2012 Nonqualified Deferred Compensation.” This Section describes the payments that would be made under that plan upon various types of termination. Since employees are immediately vested in all contributions to the plan other than our annual 5.25 percent contributions, they would receive their full account balances, less the portion of their balances attributable to such 5.25 percent contributions, upon any termination of employment other than for cause. Because participants do not vest in our 5.25 percent contributions until completion of five years of service, attainment of age 65, change in control or death, participants whose employment terminates before any such events would not receive amounts attributable to such contributions, and participants whose employment terminates after any such events would receive such amounts. However, Ms. Wolf’s employment

53

agreement provides that she will vest in her deferred compensation benefits upon a termination of employment by us without cause or by her for “good reason,” as described above under “Severance Terms in Ellen C. Wolf’s Employment Agreement.” Upon a termination for cause, all employer contributions to the deferred compensation plan would be forfeited by the participants but participants would still be entitled to their elective deferrals. Payments of vested amounts will be made at the time and in the form elected by the participant, except that a lump-sum distribution of vested amounts will be paid upon death. Amounts shown in the table are the values each named executive officer would have been entitled to given a termination on December 31, 2012.

Defined Benefit Plans. Our retirement plans are described above under “2012 Pension Benefits.” This section describes the payments that would be made under the retirement plans upon various types of termination of employment.

Voluntary termination—Despite being ineligible for retirement, Mr. Lynch and Ms. Wolf would have been entitled to benefits from the AWWPP and (for Mr. Lynch only) the ERP, upon voluntary termination at December 31, 2012. Mr. Lynch’s annual AWWPP benefit, payable as a 50 percent joint and survivor annuity beginning at age 65, is $28,336. Mr. Lynch will receive his ERP benefit as a lump sum. Ms. Wolf’s AWWPP benefit is payable as a single life annuity beginning at age 65. The life annuity annual benefit amount is $17,748. This benefit is not available as a lump sum. Upon voluntary termination, Mr. Bigelow would be eligible for an early retirement benefit described in the next section.

Retirement—At December 31, 2012, Mr. Bigelow was eligible for early retirement benefits from AWWPP and ERP. Mr. Bigelow’s estimated annual AWWPP benefit, payable immediately upon his separation from service as a 50 percent joint and survivor annuity, is $52,441 as of January 1, 2013; his annual ERP benefit is $67,647 as of January 1, 2013.

Involuntary termination without cause—Under the AWWPP and the nonqualified plan (in the case of Mr. Lynch), benefits payable upon a termination of employment without cause are in the same amount, have the same timing and are in the same form as those payable upon a voluntary termination for Ms. Wolf and Mr. Lynch.

Involuntary termination without cause following a change in control—Upon an involuntary termination of employment without cause resulting from a change in control, AWWPP and nonqualified plan benefits are in the same amount, have the same timing and are in the same form as those payable upon a voluntary termination for Ms. Wolf (with respect to the AWWPP only) and Mr. Lynch, and upon early retirement for Mr. Bigelow.

Termination for cause—In the case of termination for cause, benefits payable from the AWWPP and from the nonqualified plan are in the same amount, have the same timing and are in the same form as those payable upon a voluntary termination for Ms. Wolf and Mr. Lynch and upon early retirement for Mr. Bigelow.

Disability—Benefits payable upon a termination of employment as a result of a disability are determined under the AWWPP and the nonqualified plan in the same manner as benefits payable upon early retirement, except that disability benefits are payable immediately and without reduction for early commencement. AWWPP benefits are payable as annuities; nonqualified plan disability benefits are payable as lump sums unless the participant has elected an alternate form of payment. Messrs. Lynch and Bigelow and Ms. Wolf, who have completed the required 10 years of service, qualify for disability benefits.

Death—If Mr. Lynch had died on December 31, 2012, his surviving spouse or named beneficiary would have received benefits under the AWWPP and the ERP calculated as if he had survived to age 55 and elected a 100 percent joint and survivor annuity. The benefit under the AWWPP would have been payable to him as an annuity beginning at his 55th birthday based on the age 55 early retirement factor, the age 55 100 percent joint and survivor factor (where the survivor’s age is what it would be on his 55th birthday) and using service as of the date of death. The benefit under the ERP would have been paid to Mr. Lynch as the immediate lump-sum equivalent of an annuity determined in the same manner as under the AWWPP.

54

If Ms. Wolf or Mr. Bigelow had died on December 31, 2012, their surviving spouses or named beneficiaries would have received benefits under the AWWPP and (for Mr. Bigelow only) the ERP calculated as if they had immediately elected a 100 percent joint and survivor annuity. The benefit under the AWWPP would have been equivalent to that payable to them as an immediate annuity based on their current age early retirement factor, a 100 percent joint and survivor factor based on theirs and their survivors’ current age, and using service as of the 2003 termination date for Ms. Wolf and as of the date of death for Mr. Bigelow. The benefit under the ERP would have been paid to Mr. Bigelow as the immediate lump-sum equivalent of an annuity determined in the same manner as under the AWWPP.

For purposes of reporting these benefits in the termination tables, we assumed that Mr. Lynch and Ms. Wolf were married with spouses the same ages as the participant; we assumed Mr. Bigelow was married and used his spouse’s actual age.

Omnibus Equity Incentive Plan Awards. All stock options vest in full upon an option holders’ death or disability, or upon a change in control. In addition, performance share units will vest as follows:

• Upon a change in control, the performance share units will vest with respect to the tranches of performance share unit awards that have time-vested, based upon the assumption that target performance is achieved.

• Upon death or disability, the performance share units will performance-vest with respect to the tranches of performance share unit awards that already have time-vested, based upon actual performance as determined at the end of the performance period.

In addition, as noted above, Mr. Sterba’s 2012 Employment Agreement provides that options we granted to him in August 2010, and options and PSUs we grant to him in 2012, 2013 and 2014 will fully time-vest upon our termination of his employment without cause or termination by Mr. Sterba for good reason, as described above under “Severance Terms in Jeffrey E. Sterba’s Employment Agreement.” As also noted above, Ms. Wolf’s employment agreement provides that her awards will fully time-vest upon a termination of employment by us without cause or by Ms. Wolf for “good reason,” as described above under “Severance Terms in Ellen C. Wolf’s Employment Agreement.” All the named executive officers’ options time-vest upon death or disability, and time-vest on a prorated basis upon retirement (based on the portion of the vesting period completed prior to retirement).

Quantifications of Potential Payments on Termination or Change in Control

The following table quantifies the potential payments and benefits to which the named executive officers would have been entitled if one of several different termination of employment or change in control events occurred on December 31, 2012. The amounts shown in the table do not include certain payments and benefits to the extent they are provided on a non-discriminatory basis to non-union employees generally upon a termination of employment, including accrued salary and vacation pay, 401(k) plan benefits, continued health and welfare coverage following an involuntary termination of employment and coverage under the Consolidated Omnibus Budget Reconciliation Act (COBRA). Mr. Bigelow would also be entitled to continued coverage under American Water’s retiree welfare benefit plans. All employees are also entitled to life insurance benefits of up to 1.5 times base salary, up to a maximum amount of $200,000, if death occurs while actively employed.

With regard to all options subject to time-based vesting at December 31, 2012, the assumed values of the awards are shown in the table in the applicable columns. With regard to performance stock units that remain subject to performance-based vesting, which, upon a change of control, will vest at the target award level, the assumed value for the target amount of these performance stock units is shown in the table in the applicable columns. The value of each stock option as to which vesting is accelerated is assumed to be equal to the product of the number of shares underlying the option multiplied by the difference between the exercise price per share and $37.13 the closing price of our common stock as reported on the NYSE Composite Tape on December 31,

55

2012. For performance stock units, the value shown in the table is based on the number of performance stock units multiplied by $37.13 closing price on December 31, 2012. In addition, the value of accumulated dividends (and, for awards that remain subject to performance conditions through the end of the performance period, expected dividends for the remainder of the performance period) was included.

RELATED PERSON TRANSACTION PROCEDURES

We have adopted a written procedure for approving and ratifying related person transactions. The procedure covers transactions or series of transactions between directors, nominees, employees and stockholders who own more than 5 percent of any class of voting securities, or immediate family members of any such persons, and American Water where any of the classes of persons described above has a direct or indirect material interest.

Permission for a related person transaction may only be granted in writing in advance by the following:

• the audit committee of the board of directors in the case of transactions involving officers, directors or other employees in specified senior grade levels;

• the ethics committee (comprised of members of management) in the case of all other employees; or

• in any case, the board of directors, acting through its disinterested members only.

Transactions involving compensation of executive officers are reviewed and, if appropriate, approved by the compensation committee of the board of directors (or a group of our independent directors performing a similar function) as specified in the charter of the compensation committee.

Before any related person transaction is permitted, the following factors are to be considered:

• the related person’s interest in the transaction;

• the dollar value of the amount involved in the transaction;

• the dollar value of the related person’s interest in the transaction without regard to the amount of any profit or loss;

• whether the transaction is to be undertaken in the ordinary course of business of American Water;

• whether the transaction with the related person is proposed to be entered into on terms more favorable to American Water than terms that could have been reached with an unrelated third party;

• the purpose of, and the potential benefits to American Water of, the transaction; and

• any other information regarding the transaction or the related person that are material in light of the circumstances of the particular transaction.

Approval of a related person transaction will be granted only if it is determined that, under all of the circumstances, the transaction is in the best interests of American Water and only so long as those interests outweigh any negative effects that may arise from permitting it to occur.

AUDIT COMMITTEE REPORT

The Audit Committee assists the board in its oversight of the integrity of American Water’s financial statements, compliance with legal and regulatory requirements and the performance of the internal audit function. Management is responsible for American Water’s internal controls and financial reporting process. PricewaterhouseCoopers LLP, American Water’s independent registered public accounting firm, is responsible for performing an independent audit of American Water’s consolidated financial statements and for issuing a report on these financial statements and on the effectiveness of American Water’s internal control over financial reporting.

In this context, the Audit Committee hereby reports as follows:

1. The Audit Committee has reviewed and discussed with management and PricewaterhouseCoopers LLP the audited financial statements for the fiscal year ended December 31, 2012.

58

2. The Audit Committee has discussed with PricewaterhouseCoopers LLP the matters required to be discussed by Public Company Accounting Oversight Board Standards, AU Section 380, “Communications with Audit Committees.”

3. The Audit Committee has received the written disclosures and the letter from PricewaterhouseCoopers LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding PricewaterhouseCoopers LLP’s conversations with the Audit Committee concerning independence, and has discussed with PricewaterhouseCoopers LLP that firm’s independence.

Based on the review and discussion referred to above, the Audit Committee recommended to the board of directors that the audited financial statements be included in American Water’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, for filing with the Securities and Exchange Commission.

Respectfully submitted,

Martha Clark Goss (Chair)

Stephen P. Adik

William J. Marrazzo

(Proposal 2)

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee has appointed the firm of PricewaterhouseCoopers LLP to serve as the independent registered public accounting firm for American Water during the fiscal year ending December 31, 2013, and is recommending that the stockholders ratify this appointment. PricewaterhouseCoopers LLP has served as our auditors since 1948. Although stockholder ratification is not required by our organizational documents, or applicable law, the board of directors is submitting the selection of PricewaterhouseCoopers LLP for ratification by stockholders as a matter of good corporate practice.

In the event the stockholders fail to ratify the appointment, the audit committee will reconsider its selection. Even if the selection is ratified, the audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the audit committee believes that such a change would be in the best interests of our company and our stockholders.

A representative of PricewaterhouseCoopers LLP is expected to be present at the Annual Meeting and will have the opportunity to make a statement if he or she desires to do so. The representative also will be available to respond to appropriate questions at the Annual Meeting.

Recommendation of the Board of Directors

The board of directors unanimously recommends a vote FOR the ratification of PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm for 2013.

(Proposal 3)

ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the “Dodd-Frank Act,” enables our stockholders to vote to approve, on an advisory (non-binding) basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC’s rules. Specifically, these rules address the information we must provide in the compensation discussion and analysis, compensation tables and related disclosures included in this proxy statement. In accordance with the advisory vote of our stockholders at our 2011 Annual Meeting of Stockholders, we are providing to our stockholders the opportunity to vote annually to approve, on an advisory basis, the compensation of our named executive officers.

As described more fully under “Compensation Discussion and Analysis,” our executive compensation philosophy and programs are designed to create a positive correlation of pay to performance, consistent with sound governance principles. As explained in detail in that section, we believe that our compensation philosophy and programs contribute to our overall objective of being a trusted steward of the environment, meeting or exceeding our customers’ expectations regarding water and wastewater service and value, and promoting the safety and well-being of our workforce, while simultaneously being the trusted stewards of our investors’ capital by creating stockholder value.

Accordingly, the board recommends that our stockholders vote in favor of the following resolution:

RESOLVED, that the stockholders of American Water Works Company, Inc. approve, on an advisory basis, the compensation paid to our named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation discussion and analysis, the compensation tables and any related materials disclosed in the proxy statement for the 2013 annual meeting of stockholders.

60

While the vote is not binding on us, our compensation committee values the opinions expressed by our stockholders and will carefully consider the outcome of the vote when making future compensation decisions for our named executive officers.

Recommendation of the Board of Directors

The board of directors unanimously recommends a vote FOR the approval of the compensation of our named executive officers.

STOCKHOLDER PROPOSALS

Any stockholder who, in accordance with SEC rules, wishes to present a proposal for inclusion in the proxy materials to be distributed in connection with next year’s annual meeting must submit the proposal to the Office of the Secretary, American Water Works Company, Inc., 1025 Laurel Oak Road, Voorhees, NJ 08043. Stockholder proposals for inclusion in our proxy statement for the 2014 Annual Meeting must be received on or before November 29, 2013 and must comply in all other respects with applicable SEC rules.

Any stockholder who wishes to propose any business to be considered by the stockholders at the 2014 Annual Meeting of Stockholders other than a proposal for inclusion in the proxy statement pursuant to the SEC’s rules, or who wants to nominate a person for election to the board of directors at that meeting, must notify the Office of the Secretary of American Water in writing and provide the specified information described in our Bylaws concerning the proposed business or nominee. The notice must be delivered to or mailed to the address set forth in the preceding paragraph and received at American Water’s principal executive offices no later than February 13, 2014. The requirements for such notice are set forth in our Bylaws, a copy of which can be obtained upon request directed to the Office of the Secretary at the address set forth above.

OTHER MATTERS

At the time this proxy statement went to press, we knew of no other matters that had been properly presented to be acted upon at the Annual Meeting. If any other matter is presented at the Annual Meeting, then your proxy will vote in accordance with his or her discretion.
