The company does not have any other outstanding class of voting stock.

Voting Procedures and General Information


Broker Non-Votes
Under the rules of the New York Stock Exchange (NYSE), certain stockholder nominees (such as brokers) have the discretion to vote on routine matters, such as the ratification of the appointment of our independent registered public accounting firm, unless instructed otherwise by the beneficial owner. They do not have authority to vote on non-routine matters – such as the election of directors and the advisory vote to approve named executive officer compensation – unless they receive instruction from the beneficial owner.
A “broker non-vote” occurs when your broker submits a proxy for your shares but does not indicate a vote for a particular proposal because the broker does not have authority to vote on that proposal and has not received voting instructions from you. Broker non-votes are not counted as votes for or against the proposal in question or as abstentions, and are not counted to determine the number of votes present for the particular proposal.
Under the rules of the NYSE, if your broker holds shares in your name and delivers this proxy statement to you, the broker is entitled to vote your shares on Proposal 2 — Ratification of Independent Registered Public Accounting Firm even if the broker does not receive voting instructions from you. Without your instructions, the broker is not entitled to vote your shares on Proposal 1 — Election of Directors or Proposal 3 — Advisory Vote to Approve Named Executive Officer Compensation. We encourage you to provide instructions to your broker, bank, or other nominee. This ensures your shares will be voted at the annual meeting.
Required Vote and Method of Counting
The required vote and method of counting votes for the various business matters to be considered at the annual meeting are described in the table below. If you sign and return your proxy card without indicating your vote, your shares will be voted “FOR” each of the nominees for director, “FOR” ratification of Deloitte & Touche LLP as our independent registered public accounting firm, “FOR” the advisory vote to approve named executive officer compensation, and in accordance with the recommendations of our Board on any other matters properly brought before the annual meeting for a vote.

Voting Procedures and General Information


Householding; Receipt of Multiple Notices
Under the rules of the Securities and Exchange Commission (SEC), a single Notice of Internet Availability of Proxy Materials or set of annual reports and proxy statements may be sent to any household at which two or more stockholders reside if they appear to be members of the same family. Each stockholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information stockholders receive and reduces mailing and printing expenses. In accordance with a notice sent to certain stockholders who shared a single address, only one annual report and proxy statement were sent to that address unless any stockholder at that address requested that multiple sets of documents be sent. However, if any stockholder who agreed to householding wishes to receive a separate annual report or proxy statement for 2015 or in the future, he or she may telephone toll-free (800) 542-1061 or write to Broadridge Householding Department, 51 Mercedes Way, Edgewood, NY 11717, and the company will deliver promptly upon such written or oral request a separate Notice of Internet Availability of Proxy Materials or annual report or proxy statement. Stockholders sharing an address who wish to receive a single set of reports may do so by contacting their banks, brokers, or other nominees, if they are beneficial holders, or by contacting Broadridge at the address set forth above, if they are record holders.
Available Information
We file annual, quarterly, and current reports, proxy statements and other information with the SEC. These filings are available through a website maintained by a third-party and accessible through our company website at www.northwesternenergy.com under Our Company / Investor Relations / SEC Filings.
Our public filings also are available to the public from document retrieval services and the website maintained by the SEC at www.sec.gov. You also may read and copy any reports, proxy statements or other information that we file with the SEC at the following location of the SEC: Public Reference Room, 100 F Street NE, Room 1580, Washington, DC 20549.
Please call the SEC at (800) 732-0330 for further information on the public reference room. You also may obtain copies of this information by mail from the Public Reference Section of the SEC, 100 F Street NE, Room 1580, Washington, DC 20549, at prescribed rates.
Future Stockholder Proposals
Stockholder Proposals for Inclusion in Next Year’s Proxy Statement
To be considered for inclusion in the proxy statement for our annual meeting to be held in 2016, stockholder proposals must be received by the corporate secretary of NorthWestern Corporation not later than November 7, 2015. This notice requirement is separate from and in addition to the SEC’s requirements that a stockholder must meet in order to have a stockholder proposal included in the company’s proxy statement.
Other Stockholder Proposals for Presentation at the 2016 Annual Stockholders’ Meeting
For nominations of persons for election as a director or for any proposal that is not submitted for inclusion in next year’s proxy statement, but is instead sought to be presented directly from the floor of the 2016 Annual Stockholders’ Meeting, the company’s bylaws require that timely notice must be given to the corporate secretary. To be timely, the notice must be received by the corporate secretary of NorthWestern Corporation between December 25, 2015, and January 24, 2016.
Stockholder proposals should be delivered or mailed to and received by us in accordance with the dates set forth above and addressed to:

2016 Executive Pay Overview
Alignment of Pay with Shareholder and Customer Interests
Our executive pay program is designed to align the long-term interests of our executives, shareholders, and customers. About 77 percent of the compensation of our chief executive officer, or CEO, and about 58 percent of the compensation of our other named executive officers is at risk in the form of performance-based incentive awards that use Board-established metrics and targets, based upon advice from the Board’s independent compensation consultant. The performance metrics did not change from the prior year. We also require our executives to retain meaningful ownership of our stock. This structure encourages our executives to focus on short- and long-term performance and provides a reward to our executives, shareholders, and customers when we achieve our financial and operating objectives. Our CEO to median employee pay ratio for 2016 was 22:1.

Shareholder Feedback on Executive Pay
At our 2016 annual meeting, our 2015 named executive officer pay program was approved by 99.2 percent of the votes cast. In light of the overwhelming approval from our shareholders, we have not changed the overall structure of our named executive officer pay program for 2016. We continue to use the same executive pay components and operate within the parameters previously approved by our shareholders.
2016 Corporate Governance Overview
Our Board has nominated nine individuals for election – seven current members and two new candidates, Ms. Britt E. Ide (director and interim CEO of Big Sky Chamber of Commerce) and Ms. Linda G. Sullivan (chief financial officer for American Water). We list all nominees on the following page in Proposal No. 1—Election of Directors.
Last year, shareholders elected six of our current director nominees by at least 99.7 percent of the votes cast. Another current director nominee, Mr. Anthony T. Clark (former FERC commissioner), joined our Board in December 2016, following the April 2016 retirement of director Denton Louis Peoples. Our eighth current Board member, Ms. Dorothy M. Bradley announced in February 2017 that she would not be seeking re-election.
Each of our Board members and nominees is independent, with the sole exception of our CEO. Our Board is led by an independent chair, and our three Board committees – Audit; Compensation; and Governance – are chaired by and composed entirely of independent directors. In addition, diversity is important to our Board, as reflected in the graphs below regarding our slate of nominees.
In 2016, our Board doubled the amount of stock that they are required to hold under our stock ownership guidelines, increasing the guidelines to ten times (from five times) the annual cash Board and committee chair retainers. Other than that change, we made no material changes to our corporate governance practices in 2016.

Business
We are committed to strong corporate governance. As governance standards have evolved, we have enhanced our governance standards as appropriate to best serve the interests of our stockholders. Our commitment to corporate governance best practices has been recognized. Forbes has recognized us three times on its list of America’s Most Trustworthy Companies, a distinction awarded, according to Forbes, for transparent accounting and solid corporate governance practices. Our proxy disclosures also have been recognized by Corporate Secretary magazine. Our proxy statement last year (2014) received Corporate Secretary’s award for Best Proxy Statement (small to mid cap), and we were a finalist for Best Proxy Statement in 2012 and 2013. Glass Lewis and C-Suite magazine also have recognized our say-on-pay disclosures.
We believe that the corporate governance practices we have adopted benefit our stockholders by maintaining appropriate accountability for our company.
What We Do
Annual election of all directors.
Majority vote plus resignation standard in uncontested elections. If a director receives more “WITHHOLD AUTHORITY” votes than “FOR” votes, the director must submit a resignation for the Board to consider.
Allow stockholders owning 25 percent of our shares to call a special meeting.
Independent board. Our Board is comprised entirely of independent directors, except our CEO.
Independent Chairman.
Independent Board committees. Each of our Board committees (audit, human resources, and nominating and corporate governance) is made up solely of independent directors.
Committee authority to retain independent advisors. Each of our Board committees has the authority to retain independent advisors, which will be paid for by the company.
Code of Conduct and Ethics. We are committed to operating with honesty and integrity and maintaining the highest level of ethical conduct. Our Code of Conduct and Ethics applies to all employees, as well as the Board. We also have a separateCode of Ethics for the Chief Executive Officer and Senior Financial Officersconcerning financial reporting and other related matters.
Robust stock ownership guidelines for executive officers and directors.

Corporate Governance


What We Don’t Do
Poison pill. We do not have a stockholders rights plan or poison pill.
Hedging or pledging of company securities. We do not allow our directors, executives, or employees to hedge or pledge company securities.
Corporate political contributions. We do not make contributions to candidates for political office, political parties, or committees, or political committees organized to advance political candidates.
Supermajority voting. We do not have supermajority voting provisions in our certificate of incorporation or bylaws, except to approve (or amend provisions concerning) business combinations or mergers.
Board of Directors
Currently, we have seven members on our Board. In November 2014, we mourned the passing of our friend, colleague and Board member Philip L. Maslowe. Our Board has not filled the vacancy created by Mr. Maslowe’s passing, but instead conducted a search for an appropriately qualified individual. As a result of that search, our Board identified an individual with the expertise, experience, and skills that our Board believes will augment its collective skill set. Accordingly, our Board has nominated Jan R. Horsfall for election by our stockholders at the annual meeting.
We believe a limited number of directors helps maintain personal and group accountability. Our Board is independent in composition and outlook, led by an independent Chairman and composed of independent directors, other than our Chief Executive Officer (CEO). If elected, Mr. Horsfall also will be independent.
Unless you specifically withhold your authority to vote for the election of directors, the persons named in the accompanying proxy intend to vote “FOR” the election of each of the director nominees.
All nominees have advised the Board that they are able and willing to serve as directors. If any nominee becomes unavailable for any reason (which is not anticipated), the shares represented by the proxies may be voted for such other person or persons as may be determined by the holders of the proxies (unless a proxy contains instructions to the contrary). In no event will the proxy be voted for more than nine nominees.
Our individual Board members havevalues the diversity of its members. When selecting this slate of nominees, our Board concluded these nominees will provide insight from a number of perspectives, based on their diversity with respect to gender, age, ethnicity, skills and background, as well as location of residence. We believe these varied expertise andperspectives expand the Board’s ability to provide relevant guidance to our business.
Our Board also concluded that these individuals bring extensive professional experience from both within and outside our industry. This diversity of experience provides our Board with a vastbroad collective skill set which is
advantageous to the Board’s oversight of our company. While the industry-specific expertise possessed by certain of our Board membersthe nominees is essential, we also will benefit from the viewpoints of our directors with expertise outside our industry. These varied perspectives expand the Board’s ability to provide relevant guidance toThus, our business.

Our Board acts as a coherent team and fosters an environment that allows individual insights to contribute to the group consensus. Our Board members are focused on long-term company success and maintain an effective dialogue with management through constructive relationships which provide timely and appropriate deliberation.
Each of our current Board members has exceeded the stock ownership requirements established by our Corporate Governance Guidelines, has not sold any company stock, and continues to hold stock in excess of the ownership requirements. Each current director has been recognized as a Governance Fellow by the National Association of Corporate Directors (NACD) since 2011.
Our Board is actively engaged both inside and outside the boardroom. Each Board member has knowledge and insight that provide guidance concerning our business, with particular focus on succession planning,

Corporate Governance


corporate strategy, executive compensation, risk management, and operating performance. Our Board members spend time in our service territory interacting with our employees, customers, and community leaders. They seek and participate in learning opportunities to stay abreast of the latest industry and corporate governance developments affecting their role as directors.
Most of our Board meetings, including the annual meeting, are held in various locations throughout our service territory. This practice offers several educational opportunities for our Board members, including attending receptions of community leaders and meetings with employees. These opportunities are intended to inform our Board about the communities we serve and the issues, concerns, and successes of our employees. We believe holding Board meetings in our service territory also allows our Board to gain a broader understanding of various areas of our company by inviting non-management employees to make presentations to the Board that highlight their work. Our Board meeting agendas regularly include in-depth discussions concerning enterprise risks and different areas of our financial statements.
Our Board considers attendance at meetings and participation by directors in determining continued service on the Board. Attendance and participation is reviewed as partrecommends a vote “FOR” election of each of the Board’s annual self-evaluation process. The Board held six meetings in 2014. Eachnominees.

 Remembering our colleague and friend
In 2014, we mourned the passing of our esteemed colleague, fellow director and friend, Philip L. Maslowe. With an extensive background in leveraged buyout and turnaround situations, Phil provided valuable guidance to our company when he joined our Board in 2004 as we emerged from bankruptcy. Throughout his ten years of service to our company, we learned from his wisdom and insights and enjoyed his wit and humor. Phil was an active and important voice on our Board and a highly engaged chairman of our Human Resources Committee. His ideas for improving our proxy statement directly contributed to the Best Proxy Statement (small to mid cap) award we received in 2014 from Corporate Secretary magazine. We will miss his judgment and friendship.

Pre-approval Policies and Procedures
Rules adopted by the SEC in order to implement requirements of the Sarbanes-Oxley Act of 2002 require public company audit committees to pre-approve audit and non-audit services. Our Audit Committee follows procedures pursuant to which audit, audit-related, and tax services and all permissible non-audit services, are pre-approved by category of service. The fees are budgeted, and actual fees versus the budget are monitored throughout the year. During the year, circumstances may arise when it may become necessary to engage the independent public accountants for additional services not contemplated in the original pre-approval. In those instances, we will obtain the specific pre-approval of the Audit Committee before engaging the independent public accountants. The procedures require the Audit Committee to be informed of each service, and the procedures do not include any delegation of the Audit Committee’s responsibilities to management. The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated will report any pre-approval decisions to the Audit Committee at its next scheduled meeting.
Pursuant to the provisions of the Audit Committee Charter, before Deloitte is engaged to render audit or non-audit services, the Audit Committee must pre-approve such engagement. For 2016, the Audit Committee (or the Chair of the Audit Committee pursuant to delegated authority) pre-approved 100 percent of the tax fees
 
 
Leased Employees
In connection with their audit of our 2016 annual financial statements, more than 50 percent of Deloitte’s work was performed by full-time, permanent employees of Deloitte.
Vote Required
The affirmative vote of the holders of a majority in voting power of the shares of our common stock which are present in person or represented by proxy and entitled to vote thereon is required to ratify the appointment of Deloitte. Brokers may vote a client’s proxy in their own discretion on this proposal. Abstentions will have the same effect as a vote against the proposal. Unless instructed to the contrary in the proxy, the shares represented by the proxies will be voted “FOR” the proposal to ratify the selection of Deloitte to serve as the independent registered public accounting firm for NorthWestern Corporation for the fiscal year ending December 31, 2017.

Proposal No. 3
Advisory Vote to Approve Named Executive Officer Compensation
The Board of Directors recommends youvote “FOR” the resolution approving named executive officer pay.
We would like your input as to how we pay our named executive officers, as required by Section 14A of the Exchange Act, through an advisory vote to approve named executive officer compensation (or a say-on-pay vote). Your vote will provide insight and guidance to us and our Board regarding your sentiment about our executive pay philosophy, policies and practices, as described in this proxy statement. Our Board will consider the guidance received by the say-on-pay vote when determining executive pay for the remainder of 2017 and beyond. We ask you to support our executive pay and vote in favor of the say-on-pay resolution.
Last year, through the say-on-pay vote, over 99 percent of the votes cast approved how we pay our named executive officers. In fact, since our first say-on-pay vote in 2011, at least 94 percent of the votes cast have approved our executive pay each year.
We view your voting guidance over the years as strong support for the way we pay our executives. Thus, in 2016, we left intact the executive pay program you previously approved and continued to use four components - base salary, annual cash incentive awards, long-term incentive awards, and retention/retirement awards. We did not change the design of these components. In fact, the only changes for 2016 from the 2015 program you approved, were (1) three percent base salary increases (the same increase available to all employees) and (2) for our CEO and two of our named executive officers, an increase to the long-term incentive target opportunity to align with the market median.
Our Human Resources Committee, or Compensation Committee, and our Board believe the company’s overall executive pay program is structured to reflect a strong pay-for-performance philosophy and aligns the long-term interests of our executives and our shareholders. If you would like additional information about what we do with our executive pay program, we have provided a more detailed discussion in the Compensation Discussion and Analysis section, or CD&A, starting on page 11 of this proxy statement, and the 2016 Executive Pay section, starting on page 33.
We believe we have designed our executive pay program appropriately to align the long-term interests of management and shareholders, and the Board recommends that shareholders approve our executive pay program by voting “FOR” the following advisory resolution:
RESOLVED, that the compensation paid to the company’s 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 material disclosed in the company’s 2017 proxy statement) is hereby APPROVED.
Items of Business

This advisory vote to approve named executive officer pay is not binding on the company. However, we and our Board will take into account the result of the vote when determining future executive pay arrangements.
Vote Required
The affirmative vote of the holders of a majority in voting power of the shares of our common stock which are present in person or represented by proxy and entitled to vote thereon is required to approve the say-on-pay resolution set forth above. If your shares are held through a broker, bank, or other nominee and you do not vote your shares, your bank, broker, or other nominee may not vote your shares in this proposal. Assuming a quorum is present, broker non-votes or the failure to vote – either by not returning a properly executed proxy card or not voting in person at the annual meeting – will have no effect on the outcome of the voting on this proposal. Abstentions will have the same effect as a residentvote against the proposal. Unless instructed to the contrary in the proxy, the shares represented by the proxies will be voted “FOR” the proposal to approve, on an advisory basis, the pay of and respected civic leaderthe company’s named executive officers, as set forth in Montana, including non-public companythe company’s 2017 proxy statement.

Proposal No. 4
Advisory Vote on Frequency of Advisory Votes on Executive Compensation
The Board of Directors recommends you vote to hold a Say-on-Pay vote to approve executive pay every “1 YEAR”
In 2011, over 80 percent of our voting shareholders voted for a say-on-pay vote every year, and we have been conducting an annual say-on-pay vote ever since. Now, we would like your input again as to how often we should hold a say-on-pay vote – every one, two or three years.
Our Board believes that continuing our say-on-pay vote every year is the appropriate frequency for our company. We are committed to maintaining high standards of corporate governance. We believe that conducting the say-on-pay vote every year will provide a high level of transparency to our shareholders and a frequent, direct opportunity for our shareholders to offer feedback concerning our executive pay programs. For these reasons, our Board is asking you to vote for a say-on-pay vote every “1 YEAR.”
You have three choices for how frequently we should conduct our say-on-pay vote – every one, two or three years. You also may abstain from voting. Your vote on this proposal is an advisory vote. It is not binding on our Board. However, like in 2011, the Board will take into account the result of this year’s vote when determining the frequency of future say-on-pay votes.
The Board recommends that you vote to conduct the say-on-pay vote every “1 YEAR.” Unless instructed to the contrary in your proxy, the proxy holder(s) will vote the shares represented by your proxy to conduct the say-on-pay vote every “1 YEAR.” Please note that you are voting for how often you feel the company should conduct a say-on-pay vote. You are not voting to approve or disapprove the Board of Directors’ recommendation.
Vote Required
If your shares are held through a broker, bank, or other nominee and you do not vote your shares, your bank, broker, or other nominee may not vote your shares in this proposal. Assuming a quorum is present, broker non-votes or the failure to vote – either by not returning a properly executed proxy card or not voting in person at the annual meeting - will have no effect on the outcome of the voting on this proposal. Abstentions also will have no effect on the outcome of this proposal. Unless instructed to the contrary in the proxy, the shares represented by the proxies will be voted “FOR” the proposal to approve, on an advisory basis, the pay of the company’s named executive officers, as set forth in the company’s 2017 proxy statement.

Nomination of New Director
Over approximately the past two years, our Nominating and Corporate Governance Committee (NCG Committee) has been leading our Board through a Board succession planning process. In addition to the typical annual review of individual Board members and our Board skills matrix, the NCG Committee led a continued analysis throughout this period of the future membership of our Board as our directors approach the end of their 15-year term limits and began to assemble a list of potential candidates based on internal recommendations.
As a result, the NCG Committee possessed the foundation for conducting a search to fill the Board vacancy created by the 2014 passing of our Board member, Phil Maslowe. After gathering recommendations for potential candidates, the NCG Committee retained a search firm to assist its efforts in accordance with the powers provided by its charter. The search firm developed position specifications as directed by the NCG Committee’s (including a preference for qualified financial experts), identified additional candidates, investigated candidate interest, provided the NCG Committee with an assessment of candidate fitness for the position, coordinated in-person interviews of finalists, and conducted background/reference checks.
Throughout the search process, the NCG Committee and other members of our Board participated in reviewing the backgrounds of potential candidates, developing a short list of candidates to interview, and conducting in-person interviews with the candidates. The search process focused on identifying an individual to fill the vacancy on the Board created by Mr. Maslowe’s passing, and, as a result of a robust search process, the Board identified an individual with the skills and qualities that the Board felt would augment the Board’s collective skill set today and into the future.
Accordingly, the search process resulted in our Board extending an invitation to Jan R. Horsfall to join our Board, subject to stockholder approval at the annual meeting. Our Board determined to fill this vacancy by conducting a stockholder vote at the annual meeting, rather than exercising the Board’s rights under our bylaws to immediately fill the Board vacancy without stockholder approval. If our stockholders do not support the nomination of Mr. Horsfall, our Board may act to reduce the size of our Board rather than fill the vacancy.
We are delighted that Mr. Horsfall accepted our Board’s invitation and recommend that you vote “For” his election at the annual meeting. A summary follows of the biography and qualifications considered by our Board in connection with its nomination of Mr. Horsfall. In short, our Board nominated Mr. Horsfall because his broad executive, entrepreneurial, marketing, financial, integration, and change management experience outside of the utility industry will provide a unique, supplemental perspective to our Board discussions and decisions.

Board credentials as a current and former board member of several privately held and non-profit entities.
We believe Mr. Horsfall is Qualified to Serve on our Board because of his
● Executive experience as a chief executive officer, chief marketing officer and other positions
● Financial proficiency – financially literate (NYSE)
● Marketing background
● Experience with mergers, acquisitions and the growth and development of companies
Independent Board Chair
Our Board has placed the responsibilities of Chair with an independent member of the Board, which we believe provides optimum accountability between the Board and our management team. We believe it is beneficial to have an independent Chair whose sole responsibility is leading our Board members as they provide leadership to our executive team. Our Chair is responsible for providing leadership to the Board
and facilitating communication among the directors; setting the Board meeting agendas in consultation with the President and CEO; presiding at Board meetings, executive sessions and stockholder meetings; and serving as an ex-officio member of each Board committee. This delineation of duties allows the CEO to focus his attention on managing the day-to-day business of the company. We believe this structure provides strong leadership for our Board, while positioning our CEO as the leader of the company in the eyes of our customers, employees, and other stakeholders.
Each regularly scheduled Board and committee meeting provides the opportunity for executive sessions of the non-employee directors without management in attendance. These executive sessions are chaired, as applicable, by our Chairman or the independent chairperson of the respective committee.
Determination of Independence and Family Relationships
All of our directors are independent, with the sole exception of our CEO. A director will be considered independent if he or she qualifies as “independent” under (1) NYSE standards and any applicable laws and (2) he or she (a) has never been an employee of the company or any of its subsidiaries, (b) is not a close relative of any management employee of the company, (c) provides no services to the company, or is not employed by any firm providing major services to the company, other than as a director, and (d) receives no compensation from the company other than director fees and benefits. The Board’s determination of independence is based upon a review of the questionnaires submitted on an annual basis by each director, the company’s relevant business records, publicly available information and the applicable SEC and NYSE requirements.
Based on its review, the Board determined that all of the non-employee directors (Messrs. Adik, Draper, Dykhouse, Peoples and Mses. Bradley and Johnson) are independent as defined in the listing standards noted above. The Board also has determined that Mr. Horsfall, if elected by stockholders at the annual meeting, will be independent. Our final director, Mr. Rowe, is an executive officer of the company and, therefore, is not independent.

14

Corporate Governance


In addition to the independence assessment of our current directors and newly-nominated director, our Board reviewed the family relationships of our current directors, executive officers and newly-nominated director to determine the existence of any family relationships not more remote than first cousins. Based on this review, our Board determined that no such family relationships exist, except that current director Dana J. Dykhouse and newly-nominated director Jan R. Horsfall are first cousins.
Committees of the Board
We have three Board committees composed solely of independent directors, each with a different independent director serving as chairperson of the committee. Our Board committees are:
Audit Committee;
Human Resources Committee; and
Nominating and Corporate Governance Committee.
We hold our Board committee meetings sequentially (i.e., committee meetings do not overlap with one another). As a result of holding sequential meetings, each of our Board members attends each committee meeting. We believe this practice is highly beneficial to our Board as a whole and the company in general because each of our Board members is aware of the detailed work conducted by each Board committee. This practice also affords each of our Board members the opportunity to provide input to the committee members before a committee reaches any conclusions.
The general functions of the committees are set forth in the following paragraphs. Each of these committees has a written charter that can be found on our website at www.northwesternenergy.com under Our Company / Investor Relations / Corporate Governance.
Our Audit Committee assists the Board in fulfilling its responsibilities for oversight of (1) the company’s accounting and financial reporting processes, (2) the audits and integrity of the company’s financial statements, (3) the company’s compliance with legal and regulatory requirements, (4) the independent auditor’s qualifications and independence, (5) the performance of the company’s internal audit function and independent auditors, (6) preparation of the Audit Committee reports that the rules of the SEC require to be included in the company’s annual proxy statement, (7) significant financings and dividend policy and dividend payment recommendations, and (8) such other duties as directed by the Board.
The Board determined that each member of the Audit Committee qualifies as an audit committee financial expert under the applicable SEC regulations and that each member of the Audit Committee is independent, as defined in the listing standards of the NYSE and the SEC regulations, and financially literate within the meaning of the listing standards of the NYSE.
Our Human Resources Committee (HR Committee) acts on behalf of and with the concurrence of the Board with respect to compensation, benefits and other employment matters for executives; stock-based compensation plans for employees; the election and appointment of executive officers and other officers;

15

Corporate Governance


the assessment of the performance of the CEO; and the compensation of non-employee members of the Board. Our HR Committee has delegated the administration of our executive compensation and benefits plans to our Compensation and Benefits Department.
Each member of our HR Committee is an “outside director” within the meaning of Section 162(m) of the Internal Revenue Code, a “non-employee” director within the meaning of Rule 16b-3 under the Exchange Act, and independent under the standards of the NYSE.
The HR Committee has directly retained Towers Watson as its independent, external compensation consultant for the last several years. Towers Watson is an independent consulting firm that provides services in the areas of executive compensation and benefits and has specific expertise in evaluating compensation in the utility industry. Towers Watson reports directly to the HR Committee and, at the HR Committee’s request, provides an annual evaluation and analysis of trends in both executive compensation and director compensation. Towers Watson also evaluates other compensation issues at the direct request of the HR Committee.
In accordance with NYSE requirements approved by the SEC in 2013, the HR Committee evaluated the following six factors to assess independence and conflicts of interest before it engaged Towers Watson to do work in 2014 and 2015:
1.The provision of other services to the company by Towers Watson.
2.The amount of fees received from the company by Towers Watson, as a percentage of the firm's total revenues.
3.The policies or procedures of Towers Watson that are designed to prevent conflicts of interest.
4.Any business or personal relationship of a member of the HR Committee with the regular members of the Towers Watson executive compensation team serving the company.
5.Any stock of the company owned by the regular members of the Towers Watson executive compensation team serving the company.
6.Any business or personal relationships between the executive officers of the company and the regular members of the Towers Watson executive compensation team serving the company.
The HR Committee also obtained a representation letter from Towers Watson addressing these six factors and certain other matters related to its independence. Based on the HR Committee’s evaluation of these factors and the representations from Towers Watson, the HR Committee concluded that Towers Watson is an independent adviser and has no conflicts of interest with us.
As discussed in the “Compensation Discussion and Analysis” section of this proxy statement, the HR Committee also considers input on executive compensation from our CEO and Chief Financial Officer (CFO).
Our Nominating and Corporate Governance Committee (NCG Committee) is comprised of independent directors and assists the Board in identifying qualified individuals to become Board members, in determining the composition of the Board and its committees, in monitoring a process to assess Board effectiveness and in developing and implementing our corporate governance principles. Further, the NCG Committee reviews and oversees our position on (1) corporate social responsibilities, and (2) public policy issues that significantly affect us, our stockholders, our customers and our other key stakeholders.

16

Corporate Governance


Our NCG Committee evaluates each director candidate to determine whether such candidate should be recommended to the Board as a director nominee. In considering new individuals for nomination as directors, the NCG Committee typically solicits recommendations from its current directors and is authorized to engage third-party advisers, including search firms, to assist in the identification and evaluation of candidates. The process used by the NCG Committee with respect to our proposed new director nominee is described above in the “Nomination of New Director” discussion.
Our NCG Committee also has the responsibility for considering nominees for directors properly recommended by stockholders. A stockholder who wishes to submit a candidate for consideration at the annual meeting of stockholders must notify our Corporate Secretary in writing not less than 90 days and no more than 120 days prior to the first anniversary date of the preceding year’s annual meeting. The stockholder’s written notice must include information about each proposed nominee, including name, age, business address, principal occupation and other information required in proxy solicitations. The nomination notice also must include the nominating stockholder’s name and address, the number of shares of our common stock beneficially owned by the stockholder and any arrangements or understandings between the nominee and the stockholder. The stockholder also must furnish a statement from the nominee indicating that the nominee wishes and is able to serve as a director. The manner in which the NCG Committee evaluates candidates recommended by stockholders is generally the same as candidates from other sources. However, the NCG Committee also will seek and consider information concerning the relationship between the recommending stockholder and the candidate to determine if the candidate can represent the interests of all of the stockholders. The NCG Committee will not evaluate a candidate recommended by a stockholder unless the stockholder notice states that the potential candidate has indicated a willingness to serve as a director, to comply with the expectations and requirements for Board service publicly disclosed by NorthWestern and to provide all of the information required to conduct an evaluation.
Code of Conduct
Our Board adopted a Code of Conduct and Ethics (Code of Conduct) and reviews it annually. Our Code of Conduct embodies the standards that form our culture and sets forth expectations of conduct for all of our officers, directors, and employees and those of our subsidiary companies, including all full- and part-time employees and certain persons that provide services on our behalf. Our Code of Conduct focuses on our corporate vision, mission and values through its Compliance through SERVICE theme. You may review our Code of Conduct on our website at www.northwesternenergy.com under Our Company / Investor Relations / Corporate Governance. We intend to post on our website any amendments to, or waivers from, our Code of Conduct. In addition, our Board adopted a separate Code of Ethics for the Chief Executive Officer and Senior Financial Officers that applies to our principal executive officer, principal financial officer, and principal accounting officer or controller (or persons performing similar functions), which includes complaint procedures that specifically apply to this separate code. Our Board also annually reviews this separate code of ethics, which is available on our website at the location noted above. We intend to post on our website any amendments to, or waivers from, this special code of ethics.
Risk Oversight of the Company
Our Audit Committee is primarily responsible for overseeing the company’s risk management processes on behalf of the full Board by monitoring company processes for management’s identification and control of key strategic, operational, financial, regulatory and compliance risks. The Audit Committee receives reports from management at least quarterly regarding the company’s assessment of risks. The HR Committee oversees risks in compensation plans, and the NCG Committee oversees risks in corporate governance and social responsibilities including environmental, health and safety matters. In addition, the Audit Committee reports regularly to the full Board, which also considers the company’s risk profile. The Audit Committee and the full Board focus on the most significant risks facing the company and review the corporate risk appetite in evaluating strategic alternatives. While the Board oversees the company’s risk management, our CEO and executive Enterprise Risk Management Committee act to ensure that our enterprise risk management and business continuity programs (ERM) achieve their objectives. While management is responsible for the day-to-day risk management processes, we have structured our ERM reporting relationship through our Chief Audit and Compliance Officer who reports functionally to the Audit Committee. We believe this division of

17

Corporate Governance


responsibilities is the most effective approach for addressing the risks facing our company and that our Board leadership structure supports this approach.
Transactions with Related Persons
Our Audit Committee has adopted a written Related Persons Transaction Policy. The policy requires that any related person transaction be reviewed and approved by the Audit Committee based on its consideration of all available relevant facts and circumstances. The Audit Committee should approve a related person transaction only if it determines in good faith that such transaction is in, or is consistent with, the best interests of the company and its stockholders. No material related person transactions were identified during 2014.
Under the policy, a “related person” is an officer, director, director nominee, or five percent or more stockholder of the company, as well as any immediate family member of such individuals or any entity which is owned or controlled by any of such individuals; and a “related person transaction” is a transaction involving (1) the company, (2) a related person and (3) an aggregate annual amount in excess of $120,000.
The policy also provides ratification procedures for approval of transactions that have been commenced or consummated prior to any knowledge of the involvement of a related person and for the annual review of ongoing related person transactions to ensure that such transactions continue to remain in the best interests of the company and its stockholders. The policy is available on our website at www.northwesternenergy.com under Our Company / Investor Relations / Corporate Governance.
Hedging and Pledging Our Securities
Our Insider Trading Policy prohibits our directors and employees from engaging in transactions involving our securities and hedging, monetization, or publicly traded options. The Insider Trading Policy also prohibits our directors and employees from pledging any of our securities as collateral for a loan, unless pre-cleared by the insider trading compliance officer. None of our directors or executive officers have pledged any of our securities as collateral for a loan. The policy is available on our website at www.northwesternenergy.com under Our Company / Investor Relations / Corporate Governance.
Political Contributions Policy
As a public utility, we are subject to various laws and regulations at the federal, state, and local levels; and changes to these laws can affect our business, employees, communities and stockholders. Accordingly, we are committed to being an active and responsible corporate citizen.
We use our resources, through legally permissible participation in the political process, to advance matters of public policy that are consistent with our values, our legal obligations and our Code of Conduct. We also encourage our employees to be active in civic and community activities, including by participating in the political and democratic process.
We have a formal political contributions policy. We do not make and our policy prohibits corporate contributions to candidates for political office, political parties, or committees, or political committees organized for the advancement of political candidates, whether federal, state, or local.
On the other hand, state and local ballot initiatives and referenda on important policy issues have the potential to impact our business and our stakeholders. Accordingly, the policy permits corporate contributions in connection with such matters, as well as lobbying efforts and contributions to trade and local associations. Finally, the policy allows individual employees to make personal contributions to political action committees. The policy is available on our website at www.northwesternenergy.com under Our Company / Investor Relations / Corporate Governance.

Audit Committee Report
The Audit Committee operates pursuant to a charter that is reviewed annually and was last amended in October 2010. A summary of the Audit Committee’s oversight responsibilities can be found on page 15 of this proxy statement. A copy of the charter is available on NorthWestern’s website at www.northwesternenergy.com under Our Company / Investor Relations / Corporate Governance.
In the performance of the Audit Committee’s oversight function, and in connection with the December 31, 2014, financial statements, the Audit Committee reviewed and discussed the audited financial statements with management. The Audit Committee has discussed the matters required to be discussed by Statement on Auditing Standards No. 61, as amended, as adopted by the Public Company Accounting Oversight Board (PCAOB) in Rule 3200T. The Audit Committee received the written disclosures and the letter from Deloitte & Touche LLP (Deloitte) our independent registered public accounting firm, required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence; and the Audit Committee has discussed with Deloitte the firm’s independence. The compatibility of non-audit services was considered with the auditor’s independence.
Based on its review of the consolidated financial statements and discussions with and representations from management and Deloitte referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC.

Compensation Discussion and Analysis




Our overarching philosophy concerning executive compensation is that itwe should be structuredstructure executive pay to be market competitiveconsistent with our peers and to align the long-term interests of our executives, our stockholdersshareholders, and our customers so that the compensationpay appropriately reflects performance in achieving financial and non-financial operating objectives. In order toTo live up to ourthis philosophy, we believe that a significant portion of an executive’s compensationpay should be “at-risk”at risk in the form of performance-based incentive awards that are only paid if earned, as a result ofthe individual and company performance.performance targets are met.
Our executive compensationpay program is designed to:
Attract and retain a high-quality executive team by providing competitive compensationpay and benefits that reflect our financial and operational size;
Reward executives for both individual and company performance (based on financial, reliability, customer care, and safety metrics) through performance-based, at-risk compensation;pay; and
Maximize long-term stockholdershareholder value by putting a significant emphasis on:
on financial performance, reliability, safety, and customer satisfaction; andsatisfaction.

 What We Do
 Place a significant portion of executive compensationpay at risk in the form ofby granting incentive awards that are paid, if earned, based on continuing annual and long-term individual and company performance.
 Utilize multiple performance metrics for long-term incentive awards that align executive and stockholdershareholder interests.
 Target executive compensationpay around the median of our peers, while also considering trade area economics, turn-over, tenure, experience, and other factors.
   
 What We Don’t Do
 Use employment or golden parachute agreements.
 Provide change in control payments exceeding three times base salary and target bonus. Our only change in control provision appears in the NorthWestern Corporation Amended and Restatedour Equity Compensation Plan (Equity Compensation Plan) and provides for the immediate vesting or cash payment of any unvested equity awards upon a change in control.
 Grant stock options. No stock options are currently outstanding, and none have been issued under our Equity Compensation Plan.
 Allow option repricing or liberal share recycling. Each of these compensationThese practices are expressly prohibited under our Equity Compensation Plan.
 Promise multi-year guarantees for salary increases.
 Provide perquisites for executives that differ materially from those available to employees generally.
 Maintain a non-performance-based top hat plan or separate retirement plan available only to our executive officers. We do maintain a performance-based executive retirement / retention program, with five-year cliff vesting and a five-year payout period after the recipient’s separation from service.
 Pay tax gross-ups to our named executive officers.executives.
 Pay dividends or dividend equivalents on unvested performance shares or units.
 Allow our executives or directors to hedge or pledge company securities.
   
Pay Package
For 2016, our executive pay package included the same components as in 2015 — base salary, annual cash incentive award, and two long-term stock incentive awards. All incentive awards (cash and stock; annual and long-term) were performance-based. Unlike many of our peers, we do not offer a non-performance-based supplemental executive retirement plan.
The table on the following page provides a high level summary of our 2016 executive pay package. Please see the Pay Components section later in this CD&A for a more detailed summary of how we pay our executives.

Compensation Components
For 2014, our executive compensation package included the same components as in 2013 — base salary, annual cash incentive awards, and long-term equity incentive stock awards. All of the incentive awards (annual and long-term) were performance-based. The annual incentive award utilized financial and operational measures and were issued under our annual incentive plan. The long-term incentive stock awards were issued under our Equity Compensation Plan, targeted multi-year financial performance goals, and consisted of two components. The first component, our long-term incentive program (LTIP), was an award of performance units that cliff vest after a three-year performance period tied 50 percent to TSR (relative to our peer group) and 50 percent to earnings per share (EPS) growth and ROAE. The second component, executive retirement / retention program (ERRP), was an award of restricted share units that cliff vest after a five-year performance period that is tied to improved net income and, if earned, will be paid out over a five-year period after the executive separates from service with the company. Unlike many other companies, we do not offer a non-performance-based supplemental executive retirement plan.

Pay for Performance
Our HRCompensation Committee has designed our compensationpay program to align pay with performance. Our executives are rewarded for providing value to stockholdersshareholders and for performing relative to our peer group, which is summarizedidentified on page 2617 of this proxy statement.
Value Provided to StockholdersShareholders
Over the past three years, we have provided value to our shareholders, with total shareholder return (including reinvestment of dividends) of 45.7 percent, average EPS growth of 11.6 percent, and return on average equity of 10.3 percent.
These results we achieved for our shareholders are consistent with the results obtained under our incentive plans. With respect to our annual cash incentive plan for 2016, our net income achieved 111.6 percent of target and our safety and customer satisfaction results were at all-time highs. These operational successes resulted in a funding of our annual cash incentive plan at 113 percent of target for 2016.
The grants of long-term performance units that were made in 2014 pursuant to the LTIP vested on December 31, 2016. The performance measures associated with those grants were measured over a three-year vesting period and were tied to EPS growth, ROAE, and TSR. The company had solid results over the three-year vesting period with respect to the LTIP metrics, attaining 11.6 percent average EPS growth, 10.3 percent ROAE, and 44.5 percent TSR (eighth highest of our 14-member peer group when calculated as required by the LTIP). Based on these results, the LTIP awards paid out at 108.3 percent of target.

As highlighted above in the Executive Summary of this CD&A, the value we have provided to our stockholders over the past one-, two-, three-Compensation Discussion and five-year periods has been among the industry leaders and, for the past five years, has surpassed the S&P 500 index and the S&P utility index. An investment
in our stock of $100 at the beginning of 2014 would have turned into $135 by the end of 2014.
These results we achieved for our stockholders are consistent with the results obtained under our incentive plans. With respect to our annual cash incentive plan for 2014, our financial results combined with the results of our reliability, safety, and customer satisfaction goals resulted in a 125 percent funding of our annual incentive target for 2014.
The grants of long-term performance units that were made in 2012 vested on December 31, 2014. The performance measures associated with those grants were measured over a three-year

The company had solid results over the three-year vesting period, attaining 10.1 percent average net income growth, 10.4 percent ROAE, and 70.8 percent TSR. Our TSR ranked second highest when compared with our 14 other peer companies. Based on these results, the awards paid out at 168.4 percent of target.Analysis

TSR illustrates the growth of $100 invested in our common stock on December 31, 2009,2011, assuming reinvestment of dividends. CEO Compensation is total compensation (excluding change in pension value) as published in the proxy statement Summary Compensation Table. In 2011, 2012, and 2013, the CEO received the same adjustment to base pay for which other non-represented employees were eligible. The CEO first received a long-term stock-based incentive in 2012 (for the 2009-2011 plan), and has participated in the plan since then.

As of the record date, three of our 14 peers also haveFebruary 7, 2017, nine executives, eight of our peers have larger executive teams of ten or more members, and threemembers; while, four of our peers have fewer than nine executive officers.

Say-on-Pay Results
At our annual meeting in 2014, we asked our stockholders to approve, on an advisory basis, a say-on-pay resolution regarding the compensation of our named executive officers as disclosed in the proxy statement for that meeting. Our say-on-pay resolution and the 2013 compensation of our named executive officers was approved by 94.7 percent of the shares present and entitled to vote on the matter.
The HR Committee and the full Board reviewed the voting results received at the 2014 annual meeting concerning our say-on-pay resolution and have taken the results into account when establishing compensation for the named executive officers for 2015. The HR Committee believes the results from our 2014 annual meeting affirm our stockholders’ support of the company’s approach to executive compensation. Thus, we believe our executive compensation programs appropriately align the long-term interests of management and our stockholders.
Governance of Our Executive Compensation Program
Human Resources Committee
The HR Committee, composed solely of independent directors, acts on behalf of and with the concurrence of the Board with respect to compensation, benefits, and other employment matters for executives; stock-based compensation plans for employees; the election and appointment of executive officers and other officers; the assessment of the performance of the CEO; and the compensation of non-employee members of the Board. The HR Committee considers several factors including but not limited to (1) the desire to align management (and employee) interests with those of stockholders and customers, (2) the desire to link management pay to both annual and long-term performance, (3) the need to attract talent from both within and outside the utility industry, (4) economic circumstances including turnover and retention considerations, (5) pay for performance (financial and operational) in all areas of compensation, and (6) executives participate in same base plans available to all non-union employees, with no additional perquisites — all of which ultimately influence our executive compensation program.

Our 2016 Peer Group
Our Compensation Committee selects the members of our peer group and periodically examines whether peers continue to meet the criteria for inclusion described below. As part of this process, the Compensation Committee receives advice from its independent compensation consultant and selects a peer group that includes companies that: (1) maintain a regulated utility industry perspective, emphasizing operational excellence and customer satisfaction as a means to create shareholder value; (2) are referenced as relevant comparisons by other companies, the analyst community, and their advisors; and (3) have similar revenue, market capitalization and return-based measures of performance.

For 2016, based on these criteria and the advice of its independent compensation consultant, our Compensation Committee added OGE Energy Corp. and Otter Tail Corporation to our peer group and removed three companies that were in our 2015 peer group because of merger or acquisition activity.

Compensation ConsultantSay-on-Pay Results
In its governanceAt our annual meeting in 2016, our shareholders continued to show strong support of our executive compensationpay program, with 99.2 percent of the HRvotes approving the say-on-pay resolution.
Those 2016 voting results occurred after the Compensation Committee workstook action to approve 2016 pay. Nevertheless, the Compensation Committee and the Board reviewed that feedback from shareholders when establishing executive pay for 2017. The Compensation Committee believes the results from our 2016 annual meeting affirm our shareholders’ continuing support of the company’s approach to executive pay. Thus, the Compensation Committee made no substantive changes to executive pay for 2017.
How we set pay
Compensation Committee
The Compensation Committee, composed entirely of independent directors, is responsible for the oversight of:
Pay, benefits, and other employment matters for executives;
Stock-based pay plans for employees;
The election and appointment of executive officers and other corporate officers;
CEO performance; and
Director pay.
The Compensation Committee considers several factors when it sets executive pay — all of which ultimately influence our executive pay program.
Align Interests.
Provide pay that aligns management (and employee) interests with those of shareholders and customers.
Peer Comparison.
Establish overall pay approximating the median of our peer group and applicable position comparisons.
Attract Talent.
Set pay that will attract talent from both within and outside the utility industry.
Economic Circumstances.
Set pay based on economic circumstances, including turnover and retention considerations.
Pay for Performance.
Tie all components of incentive pay to the company’s short-and long-term financial and operational performance.
No Executive Perks.
Executives participate in same benefits plans available to all non‑union employees, with no additional perquisites, other than executive physicals.
Independent Compensation Consultant
To help determine executive pay, the Compensation Committee retains an independent compensationpay consultant, Willis Towers Watson, and, to a lesser extent, our CEO and CFO. Towers Watson, who reports directly to and is retained directly by the HR Committee, advises the HR Committee on an ongoing basis with regard tofor advice regarding the general competitive landscape and trends in compensation and executive and director compensationpay. While the Compensation Committee meets with the consultant from time to time, the chair of the Compensation Committee also communicates directly with the consultant in between Committee meetings. The consultant advises the Committee on several matters including (1) competitive analysis (including in relation to our peer group), (2) incentive plan design, (3) updates on trends in executive and director compensation, (4) peer group composition, and (5) handling other compensation-related matters as requested by the HR Committee. A Towers Watson representative attends meetings of the HR Committee as necessary and communicates directly with the chairman of the HR Committee.
Decision-Making Process and Role of Executive Officers
The HRCompensation Committee works with Willis Towers Watson to analyze competitive market data to determine appropriate base salary levels, annual incentive target levels, and long-term incentive target levels for all of our executives, paying particular attention to applicable comparisons with our peer group. When making comparisons to the peer group, the Compensation Committee seeks to establish compensation levels that approximate the median of our peer group. After determining appropriate levels, the Compensation Committee

With respect to our CEO’s compensation,pay, the HRCompensation Committee conducts an annual performance assessment of the CEO and determines appropriate adjustments to all elements of his total compensationpay based on his individual performance and company performance, taking into considerationthe company’s performance. The Compensation Committee then considers our CEO’s preference to havepreference: having a larger percentage of his pay be at-riskat risk in the form of performance-based compensation and his overall compensationpay to be below the median of his peers.
For the other executive officers, the CEO and CFO make recommendations to the HRCompensation Committee for all elements of compensationpay based on individual performance, market data from our peer group and published survey data. The HRCompensation Committee reviews, discusses, modifies, and approves, as appropriate, these compensation recommendations.

Targeted Overall CompensationPay and Competitive Analysis
CompensationPay Philosophy
We target base salary, annual cash incentive awards, and long-term equity grants, as well as total compensation,pay, to be market competitive for our executive officers. Our Compensation Committee believes that the best proxy to determine market competitiveness of pay is the median of our peer group, including individual pay components, as well as total pay. However, because comparative data is one of several tools that are used in determining executive officer compensation, competitiveness of compensation may fluctuate based on:
The levelon a number of achievement of our pre-established performance goals;factors, including:
Our TSR compared against our peer group;
Individual performance and scope of job responsibilities;
Internal equity considerations;
Market competitiveness and internal executive turnover; and
The level of achievement of our pre-established performance goals;
Our TSR compared against our peer group;
Individual performance and scope of job responsibilities;
Internal equity considerations;
Market competitiveness and internal executive turnover; and
The executive’s industry and position experience and tenure.
To align the long-term interests of our executives, shareholders, and customers, our Compensation Committee uses performance-based incentive awards to place a significant component of each executive’s pay at risk. According to

Compensation Discussion and Analysis


our Compensation Committee’s independent compensation consultant, our relative TSR performance metric that is part of our long term incentive program is set at a higher level, and is more difficult to achieve, than our peers. This structure encourages our executives to focus on both short- and long-term performance and provides a reward to our executives, shareholders, and customers when we achieve our financial and operating objectives.
In order to appropriately align the long-term interests of our executives, stockholders, and customers, we structure our executive compensation so that a significant component of an executive’s compensation is at risk in the form of performance-based incentive awards. Our HR Committee and Board establish metrics for our performance based incentive awards that, in general, are more difficult to achieve than our peers, based
on an analysis our independent compensation consultant conducted. This structure influences our executives to focus on both short- and long-term performance and provides a reward to our executives, stockholders, and customers when we achieve both our financial and operating objectives.
The target compensationpay mix for our named executive officers changed slightly in 20142016 from 2013.2015. As part of the overall compensation2016 pay package for our named executive officers in 2014, our HRCompensation Committee increased the targeted long-term incentive opportunity for threeour CEO and two of our named executive officers as described below in the 2014

Independent Compensation Consultant Data and Analysis
As a component of the HRCompensation Committee’s review of executive compensation matters,pay, Willis Towers Watson provides an analysis of the pay levels of aour peer group, as well as published survey data that focuses on the energy and utility industry, which is size-adjusted based on our revenues for appropriate market comparison. For 2014,In 2016, the published survey data included the Willis Towers Watson Compensation DataBank, William M. Mercer’s Executive Benchmark Database and Willis Towers Watson Survey Report on Top Management Compensation. The peer group data is a primary basis for setting compensationpay for our CEO and CFO because these positions are common among our peers. Both the peer group and survey data are analyzed and considered in setting compensationpay levels for the remaining named executive officers because these positions or division of responsibilities may not be common among each of our peers.
For long-term incentive purposes, Willis Towers Watson performs its analysis using the published survey data and focuses on companies in the energy services industry, specifically with annual revenues less than $3 billion. The Compensation Committee considers the responsibilities of the job performed by each of our executive officers and his or her performance, and adjusts each executive’s targeted pay amounts accordingly. As further detailed below, internal comparison with other officer positions also is considered.
In addition to these efforts, Willis Towers Watson prepares an analysis of market data compiled from the Willis Towers Watson Compensation DataBank for energy services executives. The analysis examines the target direct compensation opportunity for energy services executives, including base salary, target annual incentives, and the expected value of long-term incentives. Using regression analysis, Willis Towers Watson size-adjusts the data to reflect our revenue scope.

In addition to these efforts, Towers Watson prepares an analysis of market data compiled from the Towers Watson Compensation DataBank for energy services executives. The analysis examines the target direct compensation opportunity for energy services executives, including base salary, target annual incentives, and the expected value of long-term incentives. Using regression analysis, Towers Watson size-adjusts the data to reflect our revenue scope.
Based on Towers Watson’sthis analysis and as illustrated in the chart to the right, the direct compensationpay opportunity for our highest-paid employees is below the market median of the direct compensationpay opportunity for the highest-paid employees for energy services companies. For the top five highest-paid employees, our employees’ pay opportunity is 91 percent of the median; while our top 10, 15, and 20 highest-paid employees have a pay opportunity that is 92 percent, 87 percent and 85 percent, respectively, of the median.

We also conducted a separate analysis of the 2015 executive pay of the 13 other companies in our peer group. This internal analysis, which was based on proxy data, examined base salary, bonus, other annual compensation, equity awards, and non-equity incentive plan compensation (and excluded change in pension value). Using this analysis, our named executive officers had average pay of $1.03 million in 2015, which was less than all but three of the companies in our peer group; while the peer group median had average pay per named executive officer of approximately $1.33 million. For 2015, our CEO’s total pay was approximately 80 percent of the median

We also conducted a separate analysis of the 2013 executive compensation of the 14 other companies in our peer group. This internal analysis, which was based on proxy data, examined base salary, bonus, other annual compensation, equity awards, and non-equity incentive plan compensation (and excluded change in pension value). Using this analysis, our named executive officers had an average compensation that was less than all but four of the companies in our peer group, with an average compensation per named executive officer of approximately $856,000 versus the average compensation per named executive officer of the median of our peer group of approximately $1.3 million. For 2013, our CEO’s total compensation was approximately 63 percent of the median total compensationtotal pay of CEOs in our peer group.
These analyses demonstrate that, on average, we currentlyour highest paid employees are paid at a level that is below the middlemedian of the competitive range.our peer group and industry. We also are cognizant of prevailing economic conditions, internal pay equity, and executive turnover, which our HRCompensation Committee takes into account when determining executive compensation.
InternalCEO Pay EquityRatio and Wealth Accumulation
We believe our executive compensation programpay must be internally consistent and equitable to motivate our employees to create stockholdershareholder value. We are committed to internal pay equity, and the HRCompensation Committee monitors the relationship between the compensation ofpay our executive officers receive and the compensation ofpay our non-managerial employees. In 2014, the HRemployees receive. The Compensation Committee reviewed a comparison of CEO pay (base salary and incentive compensation)pay) to the pay of all our employees.employees in 2016. The compensation for our CEO in 20142016 was approximately 2422 times the median pay of our full-time employees.
22:1
CEO Pay Ratio
Since 2010, we have voluntarily disclosed our CEO to median employee pay ratio in our proxy statement. Beginning with our 2018 proxy statement, such disclosure will be required under the Dodd-Frank Act.
Our CEO to median employee pay ratio calculation includes all componentsis calculated in accordance with what the SEC will require in our 2018 proxy statement pursuant to Item 402(u) of compensation available to our CEO andRegulation S-K. We identified the median employee by examining the 2016 total cash compensation for all individuals, excluding our CEO, who were employed by us on December 16, 2016, the last day of our payroll year. We included all employees, whether employed on a full-time, part-time, or seasonal basis. We did not make any assumptions, adjustments, or estimates with respect to total cash compensation, and we did not annualize the compensation for any full-time employees that were not employed by us for all of 2016. We believe the use of total cash compensation for all employees is a consistently applied compensation measure because we do not widely distribute annual equity awards to employees. Approximately seven percent of our employees receive annual equity awards.
After identifying the median employee based on total cash compensation, we calculated annual total compensation for such employee using the same methodology we use for our named executive officers as summarizedset forth in the 2016 Summary Compensation Table later in this proxy statement.

The HRCompensation Committee reviews annually the wealth accumulation of our executives, considering all of the elements of total compensation paid topay each executive officer receives during the prior five-year period, including base salaries, annual cash incentive bonuses,payouts, the value of long­-termlong-term incentive awards and any special payments made to an individual executive. The HRCompensation Committee also reviews the projected value of each executive officer’s accumulated equity grants over the subsequent five-year period based upon various stock appreciation and “stay to normal retirement” scenarios. This is done to analyze not only the amount of compensationpay each executive officer has accumulated to date, but also to better understand how current equity grants may affect the amount of wealth the executive officers accumulate in the future.

Compensation Discussion & Analysis


Pay Components of Executive Compensation for 2014
   
 The primary pay components of total compensation for our executive officers for 2014in 2016 were:
 Base SalarySalary;
 Annual performance-based cash incentive awards; and
 Long-term performance-based equity incentive awards in the form of performance units and ERRP restricted share units.
   
The HRCompensation Committee believes these compensationpay components align the interests of our executives and our stockholdersshareholders by basing a significant portion of total compensationpay on performance and achievement of our short- and long-term goals. The specific mix among the individual components reflects market compensation arrangementscomparisons (primarily with respect to the median of our peer group) and individual position and performance. Base salary represents 2823 percent of our CEO’s targeted total compensationpay and, on average, 4542 percent of our other named executive officers’ targeted total compensation.pay. Performance-based awards (annual and long-term incentive) represent the remaining portion of targeted total compensation.pay.
The HRCompensation Committee also believes that our executive compensationpay program appropriately mitigates the risk associated with incentive-based pay. The HRCompensation Committee has designed the entire program and the metrics under our annual and long-term performance-based incentive componentsawards to curb inappropriate risk taking. For example, we do not offer guaranteed bonuses. In addition, our annual and long-term performance-based incentive awards utilize multiple performance metrics which vary from plan to plan, and rewards under those plans are aligned with the interests of our stockholders.shareholders. If our stockholdersshareholders benefit from our performance, our executive officers are rewarded. Our ERRP restricted share units also benefit our long-term succession and strategic plan by providing for payment only after the recipient leaves employment with us, and then over a five-year period. Furthermore, we have limited severance packages, we do not maintain a non-performance-based supplemental executive retirement plan,

and our retirement, healthcare, and welfare benefit programs for executives are generally the same as for all employees and are discussed in the “Compensation of2016 Executive Officers and Directors” Paysection of this proxy statement. Finally, we maintain robust stock ownership guidelines.guidelines for our executives. In light of these pay practices, the HRCompensation Committee believes that our executive compensationpay program appropriately address the risks associated with performance-based incentives.
Base Salary
The general guideline for determining salary levels for our executive officers, including the CEO, is to be around the middlemedian of the competitive range,our peer group, adjusted for other factors such as trade area economics, turn-over, tenure, and experience. Adjustments from marketpeer group levels are made based on experience in the position, industry experience, and individual performance and responsibilities. While we are cognizant of the competitive range, our primary goal is to compensate our executives at a level that best achieves our compensationpay philosophy, whether or not this results in actual pay for some positions that may be higher or lower than the market median. We find that survey results for particular positions can vary from year to year. Thus, we consider market trends for certain positions over a period of several years rather than a one-year period in setting compensationpay for such positions.
The HR Committee considers adjustments to base salaries for the executive officers on an annual basis. For 2014, the HR Committee felt that an increase to the base salaries of our executive officers in line with the industry average and the increases provided to our employees generally was reasonable in light of the
company’s strong operating results and increased stockholder returns in 2013. The HR Committee also considered that our executive officer base salaries remained below the median compensation of our peers even with the increase. The table to the right sets forth the base salaries for our named executive officers. The base salary adjustments for 2014 were effective April 1, 2014.

Annual Cash Incentive Awards
The overall design of our 20142016 annual cash incentive plan was the same as our previous year’s2015’s plan. However, as described in detail in the annual incentiveThe plan uses financial (net income) and operational (safety, reliability, and customer care) performance metrics discussion below, the HR Committee included additional performance metrics in 2014, with the addition of two reliability metrics related to our natural gas business and two new customer satisfaction metrics.
Annual cash incentive awards are used to motivate employees to meet and exceed annual company objectives that are a part of our strategic plan. All regular, non-representednon-union employees, including executive officers, participate in the same plan described in this section, and regular, representedannual incentive plan; while our union employees participate in a separate, but similar, management-designed program.
Each participating employee has a targeted annual cash incentive award, expressed as a percentage of base salary. Actual payouts for annual cash incentive awards reflect both (1) companythe company’s performance based on financial and operational measures and (2)against the metrics, as well as the employee’s individual performance.
There are four factors that determine the amount No portion of the final payout under the annual incentive plan:

(1) Base Salary
Base salary is the first component in the calculation of the annual cash incentive award. Base salary is described in the Base Salary section immediately preceding this Annual Cash Incentive Awards discussion.
(2) Individual Target Incentive
Each year, the HRCompensation Committee approves aan annual incentive target, incentiveexpressed as a percentage of base salary, for each executive. The target opportunity for our executive basedofficers is derived in part from peer group and competitive survey analysis data and in part by the Compensation Committee’s judgment on the internal equity of the positions, scope of job responsibilities, and external factors previously noted. Management also annuallyeach executive’s industry experience and tenure. Potential adjustments to the annual incentive target for the executive officers are considered by the Compensation Committee on an annual basis.
The Compensation Committee did not adjust the target incentive opportunity for any of our named executive officers (or any of our other executive officers) in 2016 because the Compensation Committee believed the targets were appropriate and commensurate with the responsibilities of those executives. The table to the right sets forth the 2016 annual incentive target opportunity for our named executive officers.   2016

(3) Plan Funding Percentage
Before each annual incentive plan year begins, management proposes specific performance targets for the company’splan’s financial and operational measures, which are reviewed,measures. The Compensation Committee considers the proposed targets, and after considerable discussionthe Compensation Committee and usually some modification, approved by the HR Committee as well as the Board. AtBoard approve final targets. Following the end of the fiscalplan year, the HRCompensation Committee reviews data submitted by management onregarding company performance against each of the specific performance targets and determines the degree to which each financial and operationalperformance measure was met during the year, subject to Board approval. The aggregate percentage of financial and operational measures met during the year represents the plan funding percentage for the annual incentive plan.
The funding (as a percentage of target) under the annual incentive plan has ranged from 94 percent to 108 percent for the four previous years, as set forth in the table to the right. Historical Funding (as a percentage of target)

The HRCompensation Committee may use discretion in increasing or decreasing the plan funding percentage from actual performance due to specific facts and circumstances, such as current economic conditions as well as unusual one-time events that significantly impact financial or non-financial results. The HRCompensation Committee exercises this discretion only for unusual, non-operational items. As described further below, each executive’s annual individual performance is then evaluated in order to determine a performance multiple, which is factored into the incentive payout calculation.
The target annual incentive opportunities for our executive officers are derived in part from peer group and competitive survey analysis data and in part by the HR Committee’s judgment on the internal equity of the positions, scope of job responsibilities, and the executives’ industry experience and tenure.

As reflected in the table to the right, our HR Committee adjusted the 2014 target annual incentive opportunity for one named executive officer by increasing the target opportunity to 45 percent from 40 percent. This adjustment was based upon a variety of factors including market competitiveness.
The HR Committee did not adjust the 2014 target annual incentive opportunity for any of our other named executive officers (or any of our other executive officers) because the HR Committee believed the annual incentive targets were appropriate and commensurate with the responsibilities of those executives.

As more fully described below, the actual amount of money available for awards (the award pool) is based on overall plan funding. Each year, the HR Committee determines funding of the award pool based on its assessment of overall company performance during the year, measured against pre-established financial and operational metrics.
The HR Committee determined that the metrics and relative weightings focus the organization on desired performance for the following reasons:
Net income, 55 percent of the funding opportunity – Net income was chosen as the financial metric because it is a financial measure that investors consider significant to evaluate company performance, and net income can be directly affected by individual employee and team performance.
Operational targets related to safety, reliability, and customer satisfaction, 45 percent of the funding opportunity – We believe that employee safety and providing reliable service to our customers’ satisfaction over the long term are critical to our customer commitment and regulatory obligations, which ultimately supports our financial goals and enhances stockholder value.
In order for any awards under the 20142016 annual incentive plan to be earned and paid out, a minimum ofthe company must attain at least 90 percent of the company’s budgeted net income target, must have been attained, which coincides with the threshold net income target for the plan. This metric for determining performance against our financial goal is derived from our audited financial statements. However, the HRCompensation Committee, in its discretion, may consider certain items or events as unusual when determining performance against the metric and make what it deems to be appropriate adjustments. There were no adjustments in 2016. In addition, the 20142016 annual incentive plan provided that the 2014lost-time incident rate portion of the safety portionmetric would be forfeited in the event of a work-related fatality, unless the HRCompensation Committee determined that no actions on the part of the employee or the Company contributed to the incident. Annual Incentive Plan Metrics
 
pieanninc2017.jpg
For 2014, based on company performanceIn two incredibly important ways, 2016 was a record year for all of the metrics, the annual incentive plan was funded at 125 percent of target. The narrative which follows highlights some of the results we achieved under the individual performance metrics, followed by a table with the specific results for each metric.
Net Income. In calculating performance under the net income metric, the HR Committee exercised its discretion to exclude two non-budgeted items from such calculation because the net income target is set at our budgeted net income.
First, the HR Committee excluded the revenue and expenses we incurred in connection with our acquisition of hydroelectric facilities and related assets located in Montana, which closed on November 18, 2014. The effect of excluding these transaction-related items (approximately $4.1 million after tax) increased our net income for purposes of the annual incentive plan calculation.

Compensation Discussion and Analysis




Second, the HR Committee excluded the tax benefit from the 2014 release of previously unrecognized tax benefits. The effect of excluding these tax benefits (approximately $12.6 million) decreased our net income for purpose of the annual incentive plan calculation.
If the HR Committee had not exercised its discretion to exclude these two non-budgeted items from net income, our annual incentive plan would have been funded at 131 percent, or six percent higher than the actual annual incentive plan funding of 125 percent. Thus, the HR Committee’s exercise of discretion resulted in a lower plan funding amount.
Safety.us. We achieved our best performance in company history from a safety perspective. Our two performance metrics – lost time incident rate and operation safety and health administration (OSHA) recordable rate – reflected our best historicalever annual safety performance which is a tribute to the dedication and diligence of our employees to recognize the importance of working safely every day.
Reliability. Our ability to provide reliable utility service to our customers improved over prior years. Both of our electric reliability metrics exceeded target, while one of our gas reliability metrics exceeded target and the other fell short of target.
Customer Satisfaction. In 2014, we achievedattained our highest ever JD PowersJ.D. Power overall customer satisfaction score. This independent verification of our efforts to serveOur employees completed their work more safely and our customers toappreciated their satisfaction is important. However, we failed to meet threshold on two separate, customer satisfaction measures.efforts more than ever.
The table that follows shows the associated performance metrics (including threshold, target, and maximum levels), weighting and plan payout percentage for each of the 20142016 performance measures, which resulted in the plan funding at 125113 percent of target.target for our named executive officers.

Long-Term Performance-Based Equity Incentive Awards Under the Equity Compensation Plan
We have used our Equity Compensation Plan to provide for the award of long-term, performance-based equity incentive awards to our executive officers. These performance-based awards help us achieve our compensation

philosophy of being market competitive while simultaneously aligning the interests of our executives and stockholders.shareholders.
The Equity Compensation Plan authorizes several types of stock-based awards, including restricted stock and a variety of performance-based awards. In 2014,2016, the HRCompensation Committee granted two types of long-term, equity incentive awards to our executives under the Equity Compensation Plan: (1) LTIP performance units with cliff vesting after a three-year performance period; and (2) a smaller award of ERRP restricted share units with cliff vesting after a five-year performance period and a payout over five years following the executive’s separation from service with the company. All of these 20142016 awards are performance-based and payable, if and when earned, in shares of our common stock.
LTIP Performance UnitsUnits. . The HRCompensation Committee determines the terms and restrictions applicable to grants of LTIP performance units. After the company’s financial results are available for the prior year, the HRCompensation Committee approves the annual grant of LTIP performance units to our executive officers (and approximately 100115 other participants) and selects a date (usually the date of the HR Committee’s action) when the awards will be granted, typicallyparticipants in February of each year.2016 ). The awards of LTIP performance units are intended to provide a link between executive officer compensation and long-term stockholdershareholder interests as reflected in changes in our stock price, and to motivate and reward achievement of pre-established corporate financial goals and relative TSR. The HRCompensation Committee believes that making an annual grant of LTIP performance units motivates our executive officers (and the other participants) to focus on long-term, sustainable improvement in stockholdershareholder value because (1) the award payout is tied to financial performance and continued service over a three-year period with cliff vesting at the end of such period, and (2) the ultimate value delivered is dependent upon the value of our stock.
During the performance periods summarized in the table below, the performance measures for the LTIP awards included (1) a combined financial metric comprised of ROAE and either average EPS or net income growth, contributing 50 percent of the payout, and (2) TSR relative to our peer group, also contributing 50 percent of the payout. The table below shows, for the past five completed performance periods, the contribution of these two performance measures (and our relative TSR ranking within our peer group when calculated as required by the LTIP) to the overall payout (expressed as a percentage of target).

ERRP Restricted Share UnitsUnits. . In 2011, the HRCompensation Committee made the first annual grants of ERRP restricted share units. The HRCompensation Committee instituted the practice of granting ERRP restricted share units to bring the long-term incentive component of our executives’ compensation in line with the median of our peers, while simultaneously encouraging retention with the five-year cliff vesting component and providing retirement benefits, along withbenefits. The ERRP share units also encourage succession planning and continuity of our strategic plan through the five-year payout of vested awards following the executive officer’s separation from service with the company. The key distinction between these awards and the non-performance-based supplemental executive retirement plans that certain of our peers and many other companies provide is that our ERRP restricted share units are earned based upon company performance.
The number of ERRP restricted share units that the HRCompensation Committee has granted annually has been considerably fewer than the grants of performance units. Like the performance units described above, these restricted share units are intended to provide a link between executive officer compensation and retirement planning and long-term stockholdershareholder interests and to motivate and reward achievement of pre-established corporate financial goals. The HRCompensation Committee believes that an annual grant of restricted share units motivates our executive officers to focus on long-term, sustainable improvement in our business because (1) vesting of the award is tied to financial performance and continued service over a five-year period and (2) payout of the vested award occurs over a five-year period following the executive officer’s separation from service with the company. The ERRP also encourages retention due to its five-year cliff vesting. The first opportunity for grants to vest under the ERRP is onOn December 31, 2016.2016, the first ERRP grants vested.

2016 Long-Term Incentive Program Performance Unit Grants
In February 2014,2016, the HRCompensation Committee approved grants of LTIP performance units subject to a three-year performance period with cliff vesting at the end of such period. The target long-term equity opportunities for each executive officer are derived from peer group and competitive survey data and from the HRCompensation Committee’s judgment on the internal equity of the positions and scope of job responsibilities. To determine the target value of each executive officer’s LTIP performance unit awards, the HRCompensation Committee considered the range for comparable roles within our peer group, with consideration given to the strategic value of each position. Based on these considerations, in 2014,2016, the HRCompensation Committee increased the targeted opportunity (expressed as a percentage of base salary) associated with the LTIP awards for threeour CEO and two of our named executive officers to better align with the market median.
Each executive officer’s targeted opportunity is converted into specific LTIP performance unit grants by dividing the total targeted value (the targeted percentage of base salary) by the weighted average fair market value of a share of our stock on the grant date.date, less the present value of expected dividends. The resulting calculation represents the number of LTIP performance units that were granted and will vest on December 31, 2016,2018, if all performance goals are met at the target performance level.
The target equity opportunities (value at target and number of shares) for the 2016 grants of LTIP performance units are shown in the table to the right.

After the performance period, the HRCompensation Committee calculates the actual company performance relative to the performance goals and determines the number of LTIP performance units that vest based on such performance. Depending on the calculated company performance, the exact number of LTIP performance units that vest will vary from zero to 200 percent of the target award. In addition, if earned, the value of the award on the vesting date, basedpayout will depend on the fair market valueprice of our stock on that future date, likely will differ from the value at target as reflected in the following table, which is based on the fair market value of a share of ourcommon stock on the grant date.date of payout.

In general, based on a market analysis conducted by Willis Towers Watson, our metricsperformance levels for relative TSR are established at levels higher than our peers and the market. For example, according to this market analysis, we use a ranking of 1st for maximum, while the market uses 3rd; we use a ranking of 6th for target, while the market uses 8th; and our threshold of 13th pays at ten percent, and 9th pays at 50 percent, while the market threshold of 12th pays at 50 percent.
The ROAE and simple average EPS growth levels are tied to management performance as this goal relatesthese goals relate to revenue enhancement and cost containment. The EPS performance measure is a new measure for our performance unit awards in 2014. In prior years, the awards utilized a performance measure tied to net income. With the then-pending hydro acquisition, which would significantly increase the size of our company and our net income, the HR Committee determined to include a different measure that it believed would more closely reflect the earnings growth experienced by our stockholders. A switch to EPS as a measure also captures the dilutive impact of additional equity to finance the hydro or any future transactions. TSR is determined by our common stock price change and

20142016 Executive Retention / Retirement Program Restricted Share Unit Grants
In December 2014,2016, the HRCompensation Committee approved performance-based ERRP restricted share unit grants. These restricted share unit awards are subject to a five-year performance and five-year cliff vesting period and, once vested, will be paid out in shares of the company’s common stock over a five-year period after a recipient has separated from service with the company.
Our overall compensation program does not provide any non-performance-based supplemental executive retirement benefit. The HRCompensation Committee designed and implemented the ERRP in lieu of a traditional supplemental executive retirement plan which is not performance-based but is offered by many of our peers and other companies to increase overall competitiveness. The ERRP restricted share units help to achieve our compensation philosophy of being market competitive while aligning the interests of our executives and stockholders.shareholders. It also promotes retention through the five-year cliff vesting component and benefits succession planning and continuity of our strategic plan through its fiver-yearfive-year payout following separation from service.
The long-term equity opportunity for the ERRP is derived from peer group and competitive survey data and from the HRCompensation Committee’s judgment on the internal equity of the positions and scope of job responsibilities. To determine the value of each executive officer’s ERRP restricted share unit award, the HRCompensation Committee considered the range for comparable roles within our peer group, with consideration given to each position’s strategic value, and the overall long-term equity opportunity offered to that group. For 2014,2016, the HRCompensation Committee increasedreviewed the equity incentive opportunities provided to our peer group to analyze whether the targeted ERRP restricted share unit award for each ofawards to our executive officers.

In February 2012,2014, the HRCompensation Committee approved grants of LTIP performance units, subject to a three-year performance period. The 20122014 LTIP performance unit grants vested on December 31, 2014.2016.
The 2012 LTIP performance unit grants contained both market- and performance-based components. The performance goals were independent of each other and equally weighted. The table on the following tablepage summarizes the performance measures which governed these 20122014 grants.

Depending upon actual company performance relative to these performance goals, the exact number of shares that could have vested variedranged from zero to 200 percent of the target award. As summarized above in the 2014 LTIP2016 Long-Term Incentive Program Performance Unit Grantssection, our relative TSR metrics are established at levels higher than our peers according to a market analysis conducted by the HRCompensation Committee’s independent compensation consultant. At the conclusion of the performance period, the HRCompensation Committee calculated the company’s performance relative to these goals during the three-year performance period to determine the vesting percentage for the 20122014 LTIP performance unit grants.
During the performance period, forFor the financial goals related to the 2014 LTIP performance unit grants, ROAE was 10.410.3 percent and average net incomeEPS growth was 10.111.6 percent. This financial performance resulted in a 78.478.3 percent vesting percentage for that half of the program. For our market goal, TSR was 70.844.5 percent, resulting in a ranking of 2ndeighth with respect to our peers, and contributing 90.030.0 percent with respect to that half of the program.
For purposes of our LTIP, we calculate TSR by comparing the average closing price for a share of common stock of us and our peers during the period beginning 10 days prior to the end of the performance period and ending 10 days after the performance period plus the cumulative dividends earned during the performance period, to the average closing price of a share of common stock of us and our peers during the period beginning 10 days prior to the start of the performance period and ending 10 days after the start of the performance period. Our Compensation Committee believes that calculating relative TSR using the 20-day average share price around the beginning and end of the performance period results in a more accurate reflection of return for the period that is less impacted by stock market activity on the first and last days of the performance period.
Based on the HRCompensation Committee’s calculation of these performance measures, the 20122014 LTIP performance unit grants vested at 168.4108.3 percent.
The following table summarizes the performance results with respect to each of the performance measures applicable to the 20122014 LTIP performance unit grants and the corresponding contributions to the vesting percentage.

Our Corporate Governance Guidelines require our executive officersVesting of 2011 Executive Retention / Retirement Program Grants in 2016
In December 2011, the Compensation Committee approved the first grants of ERRP restricted share units, subject to meet and maintain a specified stock ownership level. Stock ownership guidelines rangefive-year performance period from 2012 to 2016.
The 2011 ERRP restricted share unit grants contained a multiple of six times base salary for the CEO, four times base salary for the CFO, three times base salary for our Vice President and General Counsel and our Vice President - Distribution, and two times base salary for our Vice President and Controller. Each executive is restricted, absent a hardship and prior Board approval, from selling stock until his or her guideline amount is achieved and must continue to maintain thefinancial performance metric that required ownership level once it is obtained. More specific details of our officer stock ownership guidelines are available in our Corporate Governance Guidelines located on our website at www.northwesternenergy.com under Our Company / Investor Relations / CorporateGovernance.
Our Board instituted these guidelines to require our executives to hold a meaningful financial stake in the company to align our executive’s interests with thoseachieve net income during any three of our stockholders.the five years during the performance period that exceeded the company’s net income for 2011.

Retirement and Other Benefits
Retirement benefits are offered to employees hired prior to January 1, 2009, through tax-qualified company-funded pension plans and to all eligible employees through a 401(k) defined contribution plan. Both pension plans and 401(k) plans are common benefits provided in the utility and energy industry. Our executive officers, including the CEO, participate in some or all of these plans, and the terms governing the retirement benefits under these plans are the same as those available to substantially all employees. We do not offer any supplemental retirement benefits to our executive officers other than the performance-based ERRP restricted share units described above. Our healthcare, insurance, and other welfare and employee-benefit programs are generally the same for substantially all employees, including the CEO and executive officers. We share the cost of health and welfare benefits with our employees, which is dependent on the benefit

coverage option that each employee elects. Our executive officers do not receive any material perquisites or special benefits that differ materially from those available to employees generally.
Severance and Post-Termination Benefits
We provide severance and post-termination benefits to our executive officers under our severance plan. Severance and post-termination benefits are explained in detail under the “Compensation of2016 Executive Officers and Directors—PostPay—Pay After Employment Compensation”Ends section, starting on page 4737 of this proxy statement.
Non-qualified Deferred Compensation
The company provides a non-qualified deferred compensation plan, which is intended to be an unfunded plan. The 2009 Officer Deferred Compensation Plan (officer deferred plan) allows eligible officers to defer up to 100 percent of certain compensation, including base salary (subject to compliance with Section 409A of the Internal Revenue Code compensation limit), short-term incentive awards and awards earned under our Equity Compensation Plan. There are no company contributions to the officer deferred plan. Participants in the officer deferred plan may elect to have

Compensation Discussion and Analysis


deferrals credited to their account in company stock (in the form of deferred share units issued under the Equity Compensation Plan) or cash investment options that substantially mirror the qualified employee 401(k) plan investment options. The value of each deferred compensation account is adjusted periodically to reflect the gains, losses, and dividends associated with the designated investments. Officer deferred plan participants do not pay income taxes on amounts deferred or earnings thereon until those amounts are distributed from the officer deferred plan. A participant’s benefits under the officer deferred plan are fully vested and are payable after terminating employment. Benefits are paid in a lump sum unless a participant elects annual installments.
No Employment Agreements
We currently do not have employment agreements with any of our executives. We generally believe that ongoing employment agreements are not necessary to retain talented executives; however, agreements may be appropriate on a case-by-case basis, such as when an executive begins employment with us. Due to the changing marketplace in which we compete for talent, the HRCompensation Committee regularly reviews this practice to help ensure that we remain competitive in our industry.
Tax Treatment of Certain Compensation
Section 162(m) of the Internal Revenue Code limits the company deductibility of executive compensation paid to certain named executive officers to $1 million per year, but contains an exception for certain performance-based compensation. Compensation that qualifies as “performance-based compensation” is not subject to the $1 million deduction limit if, at least every five years, stockholdersshareholders approve the material terms of such performance-based compensation. The Equity Compensation Plan is structured to enable grants of equity-based incentive awards to be deductible under Section 162(m), and the material terms of the Equity Compensation Plan were approved by stockholdersshareholders at last year’s annual meeting. The HRCompensation Committee generally seeks ways to limit the impact of Section 162(m). However, the HRCompensation Committee believes that the tax deduction limitation should not compromise our ability to establish and implement incentive programs that support the compensation objectives discussed above. Accordingly, achieving these objectives and maintaining required flexibility in this regard may result in payments of compensation or grants of awards that are not deductible for federal income tax purposes. In 2014, we incurred compensation for our Named Executive Officers of approximately $118,000 that may not be deductible for tax purposes.

Compensation Committee Report
The Compensation Committee reviewed and discussed the Compensation Discussion and Analysis with management. Based on this review and discussion, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in the proxy statement and incorporated by reference into the Annual Report on Form 10-K for the year ended December 31, 2016.

These values reflect the grant date fair value of these awards as calculated utilizing the provisions of Accounting Standards Codification 718, Stock Compensation, and do not represent earned or paid compensation as the shares are subject to performance and vesting conditions. The values in the table above assume 100 percent payout based on grant date fair value. The exact number of shares issued will vary from zero to 200 percent of the target award, depending on actual company performance relative to the performance goals. See Note 1716 to the consolidated financial statements in our 20142016 Annual Report on Form 10-K for further information regarding assumptions underlying the valuation of equity awards. The value of awards for each named executive officer assuming a maximum payout based on grant date fair value would be $1,915,775$2,610,478 for Mr. Rowe; $753,590$902,812 for Mr. Bird; $490,052$632,457 for Ms. Grahame; $360,174$382,030 for Mr. Pohl; and $225,564$289,299 for Mr. Kliewer.

Pension values are dependent on many variables including years of service, earnings and actuarial assumptions. Our pension plans were closed prior to Ms. Grahame joining the company; therefore, she is not eligible to participate in a pension plan.

Non-equity Incentive Plan Awards
Non-equity incentive plan compensation includes amounts earned under the NorthWestern Energy 20142016 Annual Incentive Plan for 20142016 performance, which were paid in 2015.2017. The HRCompensation Committee reviewed 20142016 performance against plan targets and the plan achieved a payout percentage of 125113 percent, as discussed in the “CompensationCompensation Discussion and Analysis—Pay Components of Executive Compensation for 2014—Annual—Annual Cash Incentive Awards”Awards section, starting on page 3323 of this proxy statement.

Equity Incentive Plan Awards
As previously discussed in the “CompensationCompensation Discussion and Analysis—Pay Components—Long-Term Performance-Based Equity Incentive Awards2014 Compensation—Long-Term Incentive Plan Equity Awards” section in this proxy statement, the Board approved granting performance awards in 20142016 under the Equity Compensation Plan. The values of stock awards included in the table aboveon the previous page reflect the grant date fair value of these awards as calculated utilizing the provisions of Accounting Standards Codification 718, Stock Compensation, and doesdo not represent earned or paid compensation as the shares are subject to performance and vesting conditions. For the 20142016 performance unit awards, the exact number of shares issued upon vesting will vary from zero to 200 percent of the target award, depending on actual company performance relative to the performance goals. In addition, if earned, the value of a performance unit award and a restricted share unit award on the vesting date, based on the fair market value of our stock on that future date, likely will differ from the value on the grant date, which is based on the fair market value of a share of our stock and, with respect to a performance unit award, is based on the target amount for such award. See Note 1716 to the consolidated financial statements in our 20142016 Annual Report on Form 10-K for further information regarding assumptions underlying the valuation of equity awards.
Percentage of Salary Compared to Total Compensation
For 2014,2016, “Salary” for the named executive officers accounted for approximately 2826 percent to 5553 percent of total direct compensation (i.e.(i.e., salary plus targeted annual and long-term incentive compensation), while incentive compensation accounted for approximately 4547 percent to 7274 percent of total direct compensation, assuming achievement of a target level of performance for each named executive officer.

Under the NorthWestern Energy Pension Plan, a participant’s account grows based upon (1) contributions by the company made once per year, and (2) interest credits at the rate of six percent per year. Contribution ratesContributions by the company range from (a) three percent to 12 percent for eligible compensation, below the taxable wage base and fromplus (b) 1.5 percent to six percent for eligible compensation above one-half of the taxable social security wage base. Upon termination of employment, an employee who is at least 50 years of age with five years of service may begin receiving a monthly annuity or defer receiving benefits until he or she is required to take a minimum distribution.

Compensation of Executive Officers and Directors


Under the cash balance formula of the NorthWestern Corporation Pension Plan, a participant’s account grows based upon (1) annual pay credits, and (2) annual interest credits based on the average federal 30-year Treasury Bill rate for November of the preceding year. Pay credits range from three percent to 7.5 percent for compensation below the taxable wage base, and such amounts are doubled for compensation above the taxable wage base. Upon termination of employment, an employee or(or if deceased, his or her beneficiary,beneficiary) may elect to receive a lump sum equal to the cash balance in the account, a monthly annuity if age 55 or greater, or defer receiving benefits until he or she is required to take a minimum distribution.
The plans were closed to new entrants on January 1, 2009. For both pension plans, credited years of service are based on actual hire date, and pensionable earnings include base pay only. Mercer Human Resources Consulting, the actuary for our pension plans, calculated the present value of accumulated benefits using participant data provided by us.

Termination or Change in Control Arrangements
2008 Key Employee Severance Plan
Our named executive officers are participantsparticipate in the 2008our Key Employee Severance Plan (2008 Severance Plan).Plan. The 2008 Severance Plan was reviewed by the HR Committee with recommendations from professional advisers and approved by the Board. The HRCompensation Committee believes that it is appropriate for us to have a severance plan to provide a consistent means of addressing severance situations. During 2016, the Compensation Committee reviewed the terms of the plan with assistance from the Compensation Committee’s independent compensation consultant. Based on this review and the advice of its independent compensation consultant, the Compensation Committee concluded that the severance benefits provided by the plan were below market in general and with respect to our peers. Accordingly, the Compensation Committee recommended, and the Board approved, amendments to the plan to align the severance benefits with market.
The 2008Key Employee Severance Plan does not provide for change in control payments, but it does provide for the payment of severance benefits in the event an officer is terminated involuntarily without cause. Cause generally is defined in the 2008Key Employee Severance Plan as (1) fraud, misappropriation of corporate property or funds, or embezzlement; (2) malfeasance in office, misfeasance in office which is willful or grossly negligent, or nonfeasance in office which is willful or grossly negligent; (3) failure to comply with our Code of Conduct; (4) illegal conduct, gross misconduct, or dishonesty, in each case which is willful and results (or is reasonably likely to result) in substantial damage to the company; or (5) willful and continued failure by the employee to perform substantially his/her duties. For this purpose, involuntaryInvoluntary termination does not include a termination resulting from a participant’s death or disability.

$12,000

Equity Compensation Plan Change in Control Provision
All outstanding equity awards were granted under our Equity Compensation Plan. The Equity Compensation Plan, in a change in control situation, provides that either the vesting of awards shall accelerate so that awards shall vest as to the shares that otherwise would have been unvested, or the HR Committee shall arrange or otherwise provide for the payment of cash or other consideration to participants in exchange for the satisfaction and cancellation of outstanding awards. The following table shows the amount of potential stock value that would have been received, based on an assumed change in control date of December 31, 2014, outstanding equity awards at target payout, and a closing stock price on December 31, 2014, of $56.58.

Awards under our ERRP, as discussed in the “CompensationCompensation Discussion and Analysis—Other Compensation Policies—Pay Components—Long-Term Performance-Based Equity Awards under the Equity Compensation Plan” section in this proxy statement, if earned, will be paid out in shares of common stock of the company over a five-year period following the participant’s separation of service with the company.service.
Death and Disability Benefits
Our executives are covered by the standard death and disability benefits that are available to substantially all employees. In addition, upon the death or disability of a recipient of a performance unit award, such recipient

(or (or his or her executor or administrator) is entitled to receive a pro ratapro-rata portion of the award based on the number of full months such recipient was employed by the company, and the remaining portion of the award is forfeited. An award under the ERRP vests in full upon the death or disability of the recipient.
2014Assuming that our named executive officers terminated their employment as a result of death, disability or retirement on December 31, 2016, each named executive officer would have received the same payout of the earned annual cash incentive award for 2016 that is set forth in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table on page 33. Similarly, each named executive officer would have received the same payout of long-term incentive compensation for the LTIP performance units whose three-year performance period ended December 31, 2016 as reflected in the “Stock Awards - Value Realized” on LTIP Vesting column in the 2016 Stock Vested Table on page 35. The reason for the same payouts is that the individual would have been employed throughout the entire performance period for the awards.
For the remaining outstanding grants of LTIP performance units and for the outstanding grants of ERRP restricted share units, the table on the following page shows the original grants, the percentage of the original grants that would vest, and the vesting value of those grants, assuming (1) the applicable named executive officer terminated his or her

Director Pay

2016 Director CompensationPay
Compensation to our non-employee directors consists of an annual cash retainer, an annual unrestricted stock award, an annual cash retainer for the chairperson of each committee of the Board and meeting attendance fees. Non-employee directors are not eligible to participate in our retirement plans. The company also reimburses non-employee directors for the cost of participation in certain continuing education programs and the expense of traveling to Board and committee meetings. Employee directors are not compensated for service on the Board.
Non-employee directors may elect to defer up to 100 percent of any qualified cash or equity-based compensation that would be otherwise payable to them, subject to compliance with NorthWestern’s 2005 Deferred Compensation Plan for Non-employee Directors (director deferred plan) and Section 409A of the Internal Revenue Code. For those directors who defer their compensation under the director deferred plan, the meeting fee or retainer, as applicable, is the value utilized to determine the amount of deferred compensation. The deferred compensation may be invested in deferred stock units of the company’s
common stock or in designated investment options that substantially
mirror the qualified employee 401(k) plan options. Our directors defer a significant portion of their total compensation each year into the company's common stock. For 2014, our directors, deferred 73 percent of the aggregate compensation paid to all directors into the company's common stock.
In 2015, the Compensation Committee asked Willis Towers Watson to update its review of the competitive market data concerning Board compensation from peer company comparisons so that the Compensation Committee could determine 2016 compensation levels for non-employee directors. Based upon this review, the Compensation Committee made no changes to the compensation provided to our non-employee directors. The rate schedule for non-employee director compensation for 2016 is presented in the table to the right. Director Compensation Cash ($) Shares (#)

Our directors defer a significant portion of their total compensation each year into the company's common stock. For 2016, our directors deferred 51 percent of the aggregate compensation paid to all directors into the company's common stock.
Based on the election of the non-employee director, other than on account of death, he or she shall receive a distribution either in a lump sum or in approximately equal installments over a designated number of years (not to exceed ten years). Distributions of deferred share units will be equal to one share of the company’s common stock for each unit. The value of each deferred compensation account is adjusted periodically to reflect the gains, losses, and dividends associated with the designated investments.
In 2013,The following table sets forth the HR Committee asked Towers Watson to update its review of the competitive market data concerning Board2016 compensation from peer company comparisons so that the HR Committee could determine 2014 compensation levels for non-employee directors. Based upon this review, the HR Committee increased the annual stock retainers paid to the chairman of our Board (to 3,750 shares from 3,500) and individual Board members (to 2,750 shares from 2,500). The HR Committee made no other changes to the compensation provided toreceived by our non-employee directors. Following is the rate schedule for non-employee director compensation for 2014.

Our proxy disclosures also have been recognized by the NYSE Governance Services and Corporate Secretary magazine. In June of 2015, our 2014 proxy statement received NYSE's Exemplary CD&A award. That proxy statement also received Corporate Secretary’s Best Proxy Statement (small to mid-cap) award, and we were a finalist for Corporate Secretary’s Best Proxy Statement in 2012, 2013 and 2016. Glass Lewis and C-Suite magazine also have recognized our say-on-pay disclosures.

Corporate Governance


What We Don’t Do
Poison pill. We do not have a shareholders rights plan or poison pill.
Hedging of company securities. We do not allow our directors, executives, or employees to hedge company securities.
Corporate political contributions. We do not make contributions to candidates for political office, political parties, or committees, or political committees organized to advance political candidates.
Supermajority voting. We do not have supermajority voting provisions in our certificate of incorporation or bylaws, except to approve (or amend provisions concerning) certain business combinations or mergers.
Board of Directors
Our bylaws authorize a Board consisting of five to 11 directors, as determined by our Board from time to time. Our Board currently has eight members. Our Board has nominated nine directors for election at our 2017 annual meeting and has approved increasing the number of directors on our Board to nine, effective at the time of annual meeting.
Each Board member is elected at each annual meeting to serve for approximately one year, until the next annual meeting of our directors has satisfiedshareholders (or until a successor is able to serve). If any director is not elected or is unable to complete his or her term, the Board may choose a substitute to fill the vacant position or reduce the number of directors on the Board. We believe a limited number of directors helps maintain personal and group accountability.
Our Board acts as a coherent team within an environment that allows individual insights to contribute to group consensus. Our Board focuses on long-term company success and maintains an effective dialogue with management through constructive relationships which provide timely and appropriate deliberation.
Each director with more than one year of service on our Board (seven of eight) has exceeded the stock ownership guideline requirements established by our Corporate Governance Guidelines and has continuedcontinues to increase his or her ownership levelhold stock in excess of the ownership requirements. Each director with more than one year of service on our Board also has been recognized as a Governance Fellow by the National Association of Corporate Directors (NACD).
Our Board is actively engaged both inside and outside of the boardroom. Our Board members have knowledge and insight that enables them to provide guidance concerning our business, with particular focus on succession planning, corporate strategy, executive compensation, risk management, and operating performance. Our Board members spend time in our service territory interacting with our employees, customers, and community leaders. They seek and participate in learning opportunities to stay abreast of the latest industry and corporate governance developments affecting their role as directors.
Most of our Board meetings, including the annual meeting, are held throughout our service territory at approximately twelve rotating locations. This practice of rotating meeting locations offers several educational opportunities for our Board members, including attending receptions of community leaders and meetings with employees. These opportunities are intended to inform our Board about the communities we serve and the issues, concerns, and successes of our employees. Holding Board meetings in our service territory allows our Board to gain a broader understanding of various areas of our company and permits non-management employees to make presentations to the Board that highlight their work.
Our Board considers attendance at Board and shareholder meetings and participation by directors in determining continued service on the Board. Attendance and participation is reviewed as part of an annual self-evaluation process. The Board held eight meetings in 2016. Each of our current directors attended 100 percent of the meetings of the Board and of each committee on which he or she served in 2016. At our last annual meeting of shareholders in April 2016, all of our directors who were on the Board at that time were in attendance.

Board Diversity
Our Board values the diversity of its members. When considering director nominees, our Board strives to identify nominees that will provide insight to our Board from a number of perspectives, with equal importance placed on gender, age, ethnicity, skills and background, as well as location of residence. Our Board believes diversity is important because varied perspectives expand the Board’s ability to provide relevant guidance to our business. As��depicted below, our slate of director nominees demonstrate diversity.
diversitymapa01.jpg
Our individual Board members also have varied expertise and bring extensive professional experience from both within and outside our industry. This diversity of experience provides our Board with a vast collective skill set which is advantageous to the Board’s oversight of our company. While the industry-specific expertise possessed by certain of our Board members is essential, we also benefit from the viewpoints of our directors with expertise outside our industry. A high level overview of the skills and backgrounds of our director nominees follows.

Director Succession Planning
Over the past several years, our Governance Committee has led our Board through a director succession planning process. The Governance Committee initiated the process to allow for a smooth and gradual transition from our directors who were in the final third of their 15-year term limit to new directors with the right skills for our company’s future, while preserving the culture of the Board.
The process began with a review of the individual skill sets of current members and consideration of additional skills that could be beneficial for the Board in the future, with a particular focus on the company’s strategy and emerging risks. The Governance Committee also reviewed tenure limits regarding each existing Board member and discussed potential timing for inviting new members to join the Board. With that background analysis, the Governance Committee began developing a general transition timeline and assembling a list of potential candidates who were identified through a combination of personal relationships, industry knowledge, and research.

Corporate Governance


This foundational work regarding director succession planning proved beneficial when one of our directors, Mr. Denton Louis Peoples, retired in April 2016 after serving approximately eight years on our Board, and then again, in February 2017, when another director, Ms. Dorothy M. Bradley, announced her retirement, effective April 27, 2017.
With three current Board members in the final years of their 15-year term limit, our Board’s succession planning work will continue. Our Board believes maintaining a relatively small Board of approximately eight members provides several benefits. However, to preserve the Board’s culture, the size of our Board may increase temporarily so that new members can serve alongside Board members nearing the end of their terms. As important as it wasthe transition to achievenew membership concludes, we anticipate that the required stock ownership levels, wesize of our Board will return to approximately eight members.
Nomination of New Directors
At the beginning of 2016, our Board had eight members. When Mr. Peoples retired at the conclusion of his annual term in April 2016, our Board acted to reduce the size of the Board to seven members. Several months later, a non-management director and our CEO recommended that the Board consider Anthony T. Clark, former FERC commissioner, as a candidate. After meeting with Mr. Clark, the Board concluded that he has the expertise, experience, and skills to augment our Board’s collective skill set. Accordingly, in December 2016, our Board increased its size to eight members and elected Mr. Clark to serve as a director until the 2017 annual meeting. The Board has re-nominated Mr. Clark for election by our shareholders at the annual meeting, and his biography appears above with our other current directors.
During 2016 and as a result of the ongoing director succession planning process described above, our Board also began considering additional candidates for service on our Board. The Governance Committee identified a pool of candidates with solid backgrounds in finance and utility executive experience. After considering several potential candidates, the Board met with Ms. Linda G. Sullivan, who was initially recommended by a non-management director. The Board found Ms. Sullivan to possess the skills and qualities, including with respect to finance and the utility industry, that would enhance the Board’s collective skill set today and into the future. Thus, the Board nominated Ms. Sullivan to serve on our Board, subject to election by shareholders at the 2017 annual meeting.
In February 2017, Ms. Bradley announced that she would not be seeking re-election at the conclusion of her annual term in April 2017. As a resident of Montana, Ms. Bradley provided our Board with a valuable local perspective. Thus, our Board reviewed a pool of candidates who were residents of Montana. After considering and meeting with several candidates, the Board concluded that Ms. Britt E. Ide, initially recommended by a non-management director, possessed utility, engineering, legal, and other skills that would be beneficial to our Board, in addition to her local Montana knowledge. Thus, the Board also nominated Ms. Ide to serve on our Board, subject to election by shareholders at the 2017 annual meeting.
Our Board has chosen to nominate Ms. Ide and Ms. Sullivan for election by shareholders at the annual meeting, rather than exercising its right under our bylaws to increase the size of the Board by immediately fill the vacancy without shareholder approval. The Board has approved increasing the size of our Board to nine directors (from eight), effective at the time of annual meeting. If our shareholders do not support all of our director nominees, our Board may act to reduce the size of our Board rather than fill any resulting vacancy.
We are delighted that Ms. Ide and Ms. Sullivan accepted our Board’s invitation and recommend that you vote “For” their election at the annual meeting. Ms. Ide’s and Ms. Sullivan’s summary biographies are provided on the following page.

an independent Chair whose sole responsibility is leading our Board members as they provide leadership to our executive team.
Our Chair is responsible for providing leadership to the Board and facilitating communication among the directors; setting the Board meeting agendas in consultation with the CEO; presiding at Board meetings, executive sessions and shareholder meetings; and serving as an ex-officio member of each Board committee. This delineation of duties allows the CEO to focus his attention on managing the day-to-day business of the company. We believe this structure provides strong leadership for our Board, while positioning our CEO as the leader of the company in the eyes of our customers, employees, and other stakeholders.
Each regularly scheduled Board and committee meeting provides the opportunity for executive sessions of the non-employee directors have continued to retainwithout management in attendance. These executive sessions are chaired by our Board Chair or the independent Chair of the respective committee.
Determination of Independence and increase their stock ownership after meeting their stock ownership guidelines. NoneFamily Relationships
All of our directors are independent, with the sole exception of our CEO. A director is considered independent if he or she qualifies as “independent” under (1) NYSE standards and any applicable laws and (2) he or she (a) has never been an employee of the company or any of its subsidiaries, (b) is not a close relative of any management employee of the company, (c) provides no services to the company, and is not employed by any firm providing major services to the company, other than as a director, and (d) receives no compensation from the company other than director fees and benefits. The Board’s determination of independence is based upon a review of the questionnaires submitted on an annual basis by each director, the company’s relevant business records, publicly available information and the applicable SEC and NYSE requirements.
Based on its review, the Board determined that all of the non-employee directors have sold or otherwise transferred any(Messrs. Adik, Clark, Draper, Dykhouse, and Horsfall and Ms. Johnson, as well as new director nominees Mses. Ide and Sullivan) are independent as defined in the listing standards noted above. Our final director, Mr. Rowe, is an executive officer of their sharesthe company and, therefore, is not independent.
In addition to the independence assessment of our common stock. In addition, as described above, for 2014,current directors, our Board reviewed the family relationships of our current directors deferred 73 percentand executive officers to determine the existence of their aggregate compensation into the company’s common stock, even though they previously had satisfied their stock ownership guideline requirements.any family relationships not more remote than first cousins.

Our Board holds its committee meetings sequentially (i.e., committee meetings do not overlap with one another). As a result of holding sequential meetings, each of our Board members is able to attend each committee meeting. We believe this practice is highly beneficial to our Board as a whole and the company in general because each of our Board members is aware of the detailed work conducted by each Board committee. This practice also affords each of our Board members the opportunity to provide input to the committee members before a committee reaches any conclusions.

The Compensation Committee has directly retained Willis Towers Watson as its independent, external compensation consultant for the last several years.

Willis Towers Watson reports directly to the Compensation Committee and, at the Compensation Committee’s request, provides an annual evaluation and analysis of trends in both executive compensation and director compensation. Willis Towers Watson also evaluates other compensation issues at the direct request of the Compensation Committee.
In accordance with NYSE requirements approved by the SEC in 2013, the Compensation Committee evaluated the following six factors to assess independence and conflicts of interest before it engaged Willis Towers Watson to do work in 2016 and 2017:
(1)1.The provision of other services to the company by Willis Towers Watson.
2.The amount of fees received from the company by Willis Towers Watson, as a percentage of the firm's total revenues.

Director Candidate Evaluation
Our Governance Committee evaluates each director candidate to determine whether the Board should recommend such candidate as a director nominee. In considering new individuals for nomination as directors, the Governance Committee typically solicits recommendations from its current directors and is authorized to engage third-party advisers, including search firms, to assist in the identification and evaluation of candidates, if necessary.
Our goal is to maintain a diverse Board that operates cohesively and challenges management in a constructive way. The Governance Committee has not established specific minimum qualifications for director nominees or set forth specific qualities or skills that the committee believes are necessary for one or more directors to possess. Instead, in considering director candidates, the Governance Committee considers the diversity of our Board and takes into account whether the Board as a whole has the skills, experience, and background that add to and complement the


52

Corporate Governance


range of skills, experience, and background of each director, based on the following: integrity, accomplishments, business judgment, experience and education, commitment, representation of shareholders, industry knowledge, independence, and financial literacy. With the exception of the company’s CEO, all of our directors are independent, as required by our Corporate Governance Guidelines.
When nominating persons to serve on our Board, the Governance Committee considers individuals who can add value to the strategic policymaking and oversight responsibilities of the Board. A director’s ability and available time to contribute to the Board and his or her participation on other boards also are considered because we believe these are important factors that enhance the quality of the Board’s decision-making, its oversight of management, and our business overall. The Governance Committee believes that the nominees for election at this year’s annual meeting collectively possess the experience, skills, and attributes necessary to lead the company to a long and successful future.
Our Governance Committee also has the responsibility for considering nominees for directors properly recommended by shareholders. A shareholder who wishes to submit a candidate for consideration at the annual meeting of shareholders must notify our Corporate Secretary in writing not less than 90 days and no more than 120 days prior to the first anniversary date of the preceding year’s annual meeting. The shareholder’s written notice must include information about each proposed nominee, including name, age, business address, principal occupation and other information required in proxy solicitations. The nomination notice also must include the nominating shareholder’s name and address, the number of shares of our common stock beneficially owned by the shareholder and any arrangements or understandings between the nominee and the shareholder. The shareholder also must furnish a statement from the nominee indicating that the nominee wishes and is able to serve as a director.
The manner in which the Governance Committee evaluates candidates recommended by shareholders is generally the same as candidates from other sources. However, the Governance Committee also will seek and consider information concerning the relationship between the recommending shareholder and the candidate to determine if the candidate can represent the interests of all of the shareholders. The Governance Committee will not evaluate a candidate recommended by a shareholder unless the shareholder notice states that the potential candidate has indicated a willingness to serve as a director, to comply with the expectations and requirements for Board service publicly disclosed by NorthWestern and to provide all of the information required to conduct an evaluation.
Director Resignation Vote Policy
The Board has in place a Majority Plus Resignation Vote Policy for the election of directors. The policy provides that, in an uncontested election, any nominee for director who receives a greater number of “WITHHOLD AUTHORITY” votes from his or her election than votes “FOR” such election (or a Majority Withheld Vote) shall promptly offer his or her resignation following certification of the shareholder vote.
Under this policy, the Governance Committee shall promptly make a recommendation to the Board regarding the resignation offer and possible responses based on the circumstances that led to the Majority Withheld Vote, if known. The Board must act on the Governance Committee’s recommendation within 90 days following certification of the shareholder vote. Thereafter, the Board will promptly disclose its decision-making process and decision regarding whether to accept the director’s resignation offer (or the reason(s) for rejecting the resignation offer, if applicable) in a Current Report on Form 8-K.
Any director who tenders his or her resignation pursuant to this policy shall not participate in the Governance Committee’s recommendation or Board action regarding whether to accept the resignation offer. However, if each member of the Governance Committee receives a Majority Withheld Vote at the same election, then the independent directors who did not receive a Majority Withheld Vote shall appoint a committee among themselves to consider the resignation offers and recommend to the Board whether to accept them. If the only directors who did not receive a Majority Withheld Vote in the same election constitute three or fewer directors, all directors may participate in the action regarding whether to accept the resignation offers, with each director recusing himself or herself from consideration of his or her resignation offer.

Corporate Governance


Other Governance Practices
Code of Conduct
Our Board adopted a Code of Conduct and Ethics (Code of Conduct) which it reviews annually. Our Code of Conduct embodies the standards that form our culture and sets forth expectations of conduct for all of our officers, directors, and employees, including all full- and part-time employees and certain persons that provide services on our behalf. Our Code of Conduct focuses on our corporate vision, mission and values. You may review our Code of Conduct on our website at NorthWesternEnergy.com under Our Company / Investor Relations / Corporate Governance. We intend to post on our website any amendments to, or waivers from, our Code of Conduct. In addition, our Board adopted a separate Code of Ethics for the Chief Executive Officer and Senior Financial Officers that applies to our principal executive officer, principal financial officer, and principal accounting officer or controller (or persons performing similar functions), which includes complaint procedures that specifically apply to this separate code. Our Board also annually reviews this separate code of ethics, which is available on our website at the location noted above. We intend to post on our website any amendments to, or waivers from, this special code of ethics.
Risk Oversight of the Company
Our Audit Committee is primarily responsible for overseeing the company’s risk management processes on behalf of the full Board by monitoring company processes for management’s identification and control of key strategic, operational, financial, regulatory, compliance, and security risks. The Audit Committee receives reports from management at least quarterly regarding the company’s assessment of risks. The Compensation Committee oversees risks in compensation plans, and the Governance Committee oversees risks in corporate governance and social responsibilities including environmental, health and safety matters. In addition, the Audit Committee reports regularly to the full Board, which also considers the company’s risk profile. The Audit Committee and the full Board focus on the most significant risks facing the company and review the corporate risk appetite in evaluating strategic alternatives and business development opportunities. The Board oversees the company’s risk management, our CEO and executive Enterprise Risk Management Committee act to ensure that our enterprise risk management and business continuity programs (ERM) achieve their objectives. While management is responsible for the day-to-day risk management processes, we have structured our ERM reporting relationship through our Chief Audit and Compliance Officer who has a reporting relationship to the Audit Committee. We believe this division of responsibilities is the most effective approach for addressing the risks facing our company and that our Board leadership structure supports this approach.
Transactions with Related Persons
Our Audit Committee has adopted a written Related Persons Transaction Policy. The policy requires that any related person transaction be reviewed and approved by the Audit Committee based on its consideration of all available relevant facts and circumstances. The Audit Committee approves a related person transaction only if it determines in good faith that such transaction is in, or is consistent with, the best interests of the company and its shareholders. No material related person transactions were identified during 2016.
Under the policy, a “related person” is an officer, director, director nominee, or five percent or more shareholder of the company, as well as any immediate family member of such individuals or any entity which is owned or controlled by any of such individuals; and a “related person transaction” is a transaction involving (1) the company, (2) a related person and (3) an aggregate annual amount in excess of $120,000.
The policy also provides ratification procedures for approval of transactions that have been commenced or consummated prior to any knowledge of the involvement of a related person and for the annual review of ongoing related person transactions to ensure that such transactions continue to remain in the best interests of the company and its shareholders. The policy is available on our website at NorthWesternEnergy.com under Our Company / Investor Relations / Corporate Governance.

Corporate Governance


Hedging and Pledging Our Securities
Our Insider Trading Policy prohibits our directors and employees from engaging in certain transactions involving our securities, including hedging or other monetization transactions and publicly traded options. The Insider Trading Policy also prohibits our directors and employees from pledging any of our securities as collateral for a loan, unless pre-cleared by our general counsel. None of our directors or executive officers have pledged any of our securities as collateral for a loan. The policy is available on our website at NorthWesternEnergy.com under Our Company / Investor Relations / Corporate Governance.
Political Contributions Policy
As a public utility, we are subject to various laws and regulations at the federal, state, and local levels; and changes to these laws can affect our business, employees, communities and shareholders. Accordingly, we are committed to being an active and responsible corporate citizen.
We use our resources, through legally permissible participation in the political process, to advance matters of public policy that are consistent with our values, our legal obligations and our Code of Conduct. We also encourage our employees to be active in civic and community activities, including by participating in the political and democratic process.
We have a formal political contributions policy. We do not make (and our policy prohibits) corporate contributions to candidates for political office, political parties, or committees, or political committees organized for the advancement of political candidates, whether federal, state, or local.
State and local ballot initiatives and referenda on important policy issues do have the potential to impact our business and our stakeholders. Accordingly, the policy permits corporate contributions in connection with such matters, as well as lobbying efforts and contributions to trade and local associations. In addition, the policy allows individual employees to make personal contributions to political action committees. The policy is available on our website at NorthWesternEnergy.com under Our Company / Investor Relations / Corporate Governance.

Stock Ownership Guidelines
We believe it is important that our interests are aligned with the interests of our shareholders. Accordingly, our Board has established robust stock ownership guidelines for our non-employee directors and executive officers. Our stock ownership guidelines are set forth in our Corporate Governance Guidelines on our website at NorthWesternEnergy.com under Our Company / Investor Relations / Corporate Governance.
In 2016, our Board doubled the amount of stock ownership required for non-employee directors. Under the increased stock ownership guidelines, each non-employee director must retain at least ten times the value of his or her annual cash Board and committee chair retainer(s) in common stock or deferred stock units within five years of commencing service on our Board. The previous guideline was five times.
For executives, the stock ownership guidelines are six times base salary for the CEO, four times base salary for the CFO, three times base salary for our Vice President and General Counsel and our Vice President - Distribution, and two times base salary for our Vice President - Customer Care, Communications and Human Resources.


56

Stock Ownership Information

Each executive is restricted, absent a hardship and prior Board approval, from selling stock until his or her guideline amount is achieved and must continue to maintain the required ownership level once it is obtained.
Our Board instituted stock ownership guidelines to require its members and our executives to hold a meaningful financial stake in the company to align our interests with those of our shareholders. As summarized below, all of our directors and our named executive officers who have been serving more than one year have satisfied his or her applicable stock ownership guideline.
As important as it was to achieve the required stock ownership levels, we believe it is equally significant that our non-employee directors have continued to retain and increase their stock ownership after meeting their stock ownership guidelines. For 2016, our directors deferred 51 percent of their aggregate compensation into the company’s common stock, even though they previously had satisfied their stock ownership guideline requirements.

In accordanceAudit Committee reviewed and discussed the audited financial statements with our certificate of incorporation and our bylaws, all members of our Board are elected annually, to serve until the next annual meeting of stockholders and until their successors are duly elected and qualify.

Proposal 1 — Election of Directors


Our goal is to maintain a diverse Board that operates cohesively and challenges management in a constructive way. The NCG Committee has not established specific minimum qualifications for director nominees or set forth specific qualities or skills that the committee believes are necessary for one or more directors to possess. Instead, in considering director candidates, the NCG Committee considers the diversity of our Board and takes into account whether the Board as a whole has the skills, experience, and background that add to and complement the range of skills, experience, and background of each director, based on the following: integrity, accomplishments, business judgment, experience and education, commitment, representation of stockholders, industry knowledge, independence, financial literacy, race, and gender. With the exception of the company’s CEO, all of our directors are independent, as required by our Corporate Governance Guidelines. Our Board also determined that no family relationships exist with any current directors, executive officers or newly-nominated directors, except that current director Dana Dykhouse and newly-nominated director Jan Horsfall are first cousins.
When nominating persons to serve on our Board, the NCG Committee considers individuals who can add value to the strategic policymaking and oversight responsibilities of the Board and provide skills and personal experiences that add to and complement the skills, experience, and background of the Board as a whole and are needed to achieve the company’s corporate objectives. A director’s ability to contribute to the Board, the time he or she has available and his or her participation on other boards also are considered because we believe these are important factors that enhance the quality of the Board’s decision-making, its oversight of management, and our business overall. The NCG Committee believes that our incumbent Board members, along with the new nominee, collectively possess the experience, skills, and attributes necessary to lead the company to a long and successful future. Biographical information and the individual qualifications of each nominee are described beginning on page 10 of this proxy statement.
Unless authority to vote for the election of directors has been specifically withheld, the persons named in the accompanying proxy intend to vote “FOR” the election of director nominees Adik, Bradley, Draper, Dykhouse, Horsfall, Johnson, Peoples, and Rowe to hold office as directors until the next annual meeting of stockholders in 2016 and until their successors are duly elected and qualified. All nominees have advised the Board that they are able and willing to serve as directors.
If any nominee becomes unavailable for any reason (which is not anticipated), the shares represented by the proxies may be voted for such other person or persons as may be determined by the holders of the proxies (unless a proxy contains instructions to the contrary). In no event will the proxy be voted for more than eight nominees.
Directors will be elected by a favorable vote of a plurality of the shares of voting stock present and entitled to vote, in person or by proxy, at the annual meeting. You may vote “FOR” all of the nominees or you may “WITHHOLD AUTHORITY” for one or more of the nominees. Withheld votes will not count as votes cast for the nominee, but will count for purposes of determining whether a quorum is present. Stockholders do not have the right to cumulate their vote for directors. Abstentions or broker non-votes as to the election of directors will not affect the election of the candidates receiving a plurality of votes; however, under our Majority Plus Resignation Vote Policy described below, if a nominee for director receives more “WITHHOLD AUTHORITY” votes than “FOR” votes, such nominee shall immediately tender his or her resignation under the procedures in the policy.
Director Majority Plus Resignation Vote Policy
The Board has in place a Majority Plus Resignation Vote Policy for the election of directors. The policy provides that, in an uncontested election, any nominee for director who receives a greater number of “WITHHOLD AUTHORITY” votes from his or her election than votes “FOR” such election (or a Majority Withheld Vote) shall promptly tender his or her resignation following certification of the stockholder vote.
Under this policy, the NCG Committee shall promptly consider the resignation offer and a range of possible responses based on the circumstances that led to the Majority Withheld Vote, if known, and make a recommendation to the Board. The Board will act on the NCG Committee’s recommendation within 90 days following certification of the stockholder vote. Thereafter, the Board will promptly disclose its decision-making

Proposal 1 — Election of Directors




process and decision regarding whether to accept the director’s resignation offer (or the reason(s) for rejecting the resignation offer, if applicable) in a Current Report on Form 8-K furnished to the SEC.
Any director who tenders his or her resignation pursuant to this provision shall not participate in the NCG Committee’s recommendation or Board action regarding whether to accept the resignation offer. However, if each member of the NCG Committee receives a Majority Withheld Vote at the same election, then the independent directors who did not receive a Majority Withheld Vote shall appoint a committee among themselves to consider the resignation offers and recommend to the Board whether to accept them. If the only directors who did not receive a Majority Withheld Vote in the same election constitute three or fewer directors, all directors may participate in the action regarding whether to accept the resignation offers, with each director recusing himself or herself from consideration of his or her resignation offer.
Proposal 2
Ratification of Independent Registered Public Accounting Firm
Our Audit Committee has selecteddiscussed the matters required to be discussed by Statement on Auditing Standards No. 61, as amended, as adopted by the Public Company Accounting Oversight Board (PCAOB) in Rule 3200T. The Audit Committee received the written disclosures and the letter from Deloitte & Touche LLP as(Deloitte), our independent registered public accounting firm, to audit ourrequired by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence; and the Audit Committee has discussed with Deloitte the firm’s independence. The compatibility of non-audit services was considered with the auditor’s independence.
Based on its review of the consolidated financial statements and discussions with and representations from management and Deloitte referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the year endingended December 31, 2015, and recommends that stockholders vote for ratification of such appointment. Although action by2016, filed with the stockholders is not required by law, the Audit Committee and the Board have determined that it is desirable to request approval of this selection by the stockholders. Notwithstanding the selection, the Audit Committee, in its discretion, may direct the appointment of a new independent registered public accounting firm at any time during the year if the Audit Committee feels that such a change would be in the best interests of the company and its stockholders. In the event of a negative vote on ratification, the Audit Committee will reconsider its selection.SEC.
Representatives of Deloitte will be present at the annual meeting and will be given the opportunity to make a statement if they so desire and to respond to appropriate questions. The following table is a summary of the fees billed to us by Deloitte for professional services for the fiscal years ended December 31, 2014 and 2013:

Audit Fees
Audit fees consist of fees billed for professional services rendered for the audit of our financial statements, internal control over financial reporting, review of the interim financial statements included in quarterly reports, services in connection with debt and equity securities offerings, and services that are normally provided by Deloitte in connection with statutory and regulatory filings or engagements. For 2014, this amount includes estimated billings for the completion of the 2014 audit, which Deloitte rendered after year-end.

Audit-related Fees
Audit-related fees consist of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under “Audit Fees.” There were no audit-related fees in fiscal 2014 and 2013.
Tax Fees
Tax fees consist of fees billed for tax compliance, tax advice and tax planning.
All Other Fees
All other fees consist of fees for products and services other than the services reported above. In fiscal years 2014 and 2013, there were no other fees.
Pre-approval Policies and Procedures
Rules adopted by the SEC in order to implement requirements of the Sarbanes-Oxley Act of 2002 require public company audit committees to pre-approve audit and non-audit services. Our Audit Committee follows procedures pursuant to which audit, audit-related, and tax services and all permissible non-audit services, are pre-approved by category of service. The fees are budgeted, and actual fees versus the budget are monitored throughout the year. During the year, circumstances may arise when it may become necessary to engage the independent public accountants for additional services not contemplated in the original pre-approval. In those instances, we will obtain the specific pre-approval of the Audit Committee before engaging the independent public accountants. The procedures require the Audit Committee to be informed of each service, and the procedures do not include any delegation of the Audit Committee’s responsibilities to management. The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated will report any pre-approval decisions to the Audit Committee at its next scheduled meeting.
Pursuant to the provisions of the Audit Committee Charter, before Deloitte is engaged to render audit or non-audit services, the Audit Committee must pre-approve such engagement. For 2014, the Audit Committee (or the Chairman of the Audit Committee pursuant to delegated authority) pre-approved 100 percent of the tax fees.
Leased Employees
In connection with their audit of our 2014 annual financial statements, more than 50 percent of Deloitte’s work was performed by full-time, permanent employees of Deloitte.
The affirmative vote of the holders of a majority in voting power of the shares of our common stock which are present in person or represented by proxy and entitled to vote thereon is required to ratify the selection of Deloitte. Brokers may vote a client’s proxy in their own discretion on this proposal, and accordingly, “broker non-votes” will not affect the outcome of the vote on the proposal. Abstentions will have the same effect as a vote against the proposal. Unless instructed to the contrary in the proxy, the shares represented by the proxies will be voted “FOR” the proposal to ratify the selection of Deloitte to serve as the independent registered public accounting firm for NorthWestern Corporation for the fiscal year ending December 31, 2015.

Proposal 3 — Advisory Vote to Approve Named Executive Officer Compensation


Proposal 3
Advisory Vote to Approve Named Executive Officer Compensation
The company is providing stockholders an opportunity to provide an advisory vote to approve named executive officer compensation (or a say-on-pay vote), as required by Section 14A of the Exchange Act. Through the say-on-pay vote, we are asking you to support the compensation of our named executive officers as we have described it in this proxy statement. The say-on-pay vote is seeking advisory approval of the compensation of our named executive officers. We hold advisory votes on executive compensation every year. Our Board decided on annual votes after most of our stockholders voted for that preference in 2011. We will continue to hold annual advisory votes on executive compensation until our next vote on the frequency of stockholder votes on executive compensation, which will occur at our 2017 annual meeting.
At our annual meeting in 2014, we asked our stockholders to approve, on an advisory basis, a say-on-pay resolution regarding the compensation of our named executive officers, as disclosed in the proxy statement for that meeting. Our say-on-pay resolution and the 2013 compensation of our named executive officers was approved by 94.7 percent of the shares present and entitled to vote on the matter.
Your say-on-pay vote will provide insight and guidance to us and our Board regarding your sentiment about our executive compensation philosophy, policies and practices. While the say-on-pay vote is advisory and not binding on our company, we and our Board will consider the guidance received by the vote when determining executive compensation for the remainder of 2015 and beyond. For the reasons summarized below, we ask that you support our executive compensation and vote in favor of the say-on-pay proposal outlined below.
We consider our executive compensation programs to be instrumental in helping us achieve strong financial performance and other key non-financial objectives, such as safety, reliability, and customer satisfaction. Our programs are designed to attract, motivate, and retain a highly qualified executive team that is able to achieve corporate objectives and create long-term stockholder value. Our HR Committee and our Board believe the company’s overall executive compensation program is structured to reflect a strong pay-for-performance philosophy and aligns the long-term interests of our executives and our stockholders. The “Compensation Discussion and Analysis,” or CD&A, section, starting on page 20 of this proxy statement, and the “Compensation of Executive Officers and Directors” section, starting on page 43, provide more detailed discussions of our specific executive compensation programs.
Our compensation programs are substantially tied to our key business objectives and the success of our stockholders. As described in the “Compensation Discussion and Analysis” section, one component of our compensation philosophy is that a significant portion of our executives’ compensation should be at-risk in the form of incentive awards that are paid, if earned, based on individual and company performance. Our short-term and long-term incentive programs demonstrate this philosophy. More than half (55 percent) of the weighting of the potential annual incentive payment an executive may earn is tied to the company’s success in achieving a net income target established by our HR Committee and approved by our Board. The remainder of the potential annual incentive payment is focused on achieving excellence in operations. With respect to our long-term incentive program, the number of shares actually earned pursuant to long-term incentive awards is based on ROAE, earnings per share growth (prior to 2014 our long-term incentive programs used net income growth instead of earnings per share growth) and TSR relative to our peer group. If the value we deliver to our stockholders declines, so, too, does the compensation we deliver to our executives.
In addition, we have designed the framework of our short-term and long-term incentive programs for the long haul. Our Board established the framework for our short-term incentive program in 2005. Since establishment, the primary revisions to the program have been with respect to annual targets, generally, to require improvement on a year-over-year basis. Our Board established a long-term incentive plan in 2005, our Equity Compensation Plan. In 2009, our Board granted performance-based awards to the company’s senior

59

Proposal 3 — Advisory Vote to Approve Named Executive Officer Compensation


employees whose work directly affects our financial results and incorporated performance-based metrics over a three-year period with cliff vesting at the end of that period. The first payouts under such awards occurred in early 2012. In addition, payout of our executive retention / retirement program restricted share units are conditioned on the company’s financial performance over a five-year period with cliff vesting at the end of such period and, if earned, are paid out over a five-year period after the executive’s separation from service with the company.
We believe this framework has contributed greatly to aligning the interests of our stockholders and executives. As illustrated by the following graphics, relative to our peers, we are providing strong financial results, with our TSR over the past one- and three-year periods in the top quartile. Meanwhile, our CEO pay has been among the lowest in our peer group, ranking third lowest over the same periods. The CD&A contains additional details concerning our performance and compensation relative to our peers as depicted in the graphics below.
3-YEAR
3rd Lowest CEO Pay2nd Highest TSR

1-YEAR
3rd Lowest CEO Pay3rd Highest TSR
                                    of 15 Peers                         of 15 Peers
Another component of our compensation philosophy is to target compensation around the middle of the competitive total compensation range, while also considering various factors, including trade area economics, turn-over, tenure, experience and other factors. Our HR Committee closely monitors the compensation programs and pay levels of executives from similar companies as to size and complexity with the assistance of an independent compensation consultant, Towers Watson.

Proposal 3 — Advisory Vote to Approve Named Executive Officer Compensation


Our compensation philosophy also is reflected in what we don’t do:
We do not make multi-year guarantees for salary increases to our named executive officers.
We do not have perquisites for current, former, and/or retired executives that differ materially from those available to employees generally.
We do not have any change in control payments exceeding three times base salary and target bonus. Our only change in control provision appears in the Equity Compensation Plan and provides for the immediate vesting or cash payment of any unvested equity awards upon a change in control.
We do not have employment or golden parachute agreements with any of our executive officers.
We do not have a non-performance-based top hat plan or separate retirement plan available only to our executive officers. We do maintain a performance-based executive retention / retirement program.
We do not provide tax gross-ups to our named executive officers.
We do not pay dividends or dividend equivalents on unvested performance shares or units.
We do not allow our executives to hedge or pledge company securities.
Finally, we believe our compensation philosophy is reflected in the high level of corporate governance we maintain over our executive compensation programs. Our HR Committee consists entirely of independent members. Moreover, our HR Committee, our CEO, and our executive in charge of human resources engage in an annual talent review process to address succession and executive development for our CEO and other key executives. Our HR Committee also conducts an annual performance assessment of our CEO and determines appropriate adjustments to all elements of his total compensation based on individual and company performance.
We believe that the summary information we have provided with this proposal and the more detailed descriptions provided elsewhere in this proxy statement demonstrate that we and our HR Committee have designed our executive compensation programs appropriately to align the long-term interests of management and stockholders.
For all of these reasons, including what we do and don’t do, your vote in support of the compensation of our named executive officers is requested. Accordingly, the Board recommends that stockholders approve our executive compensation program by voting “FOR” the following advisory resolution:
RESOLVED, that the compensation paid to the company’s 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 material disclosed in this proxy statement) is hereby APPROVED.
This advisory vote to approve named executive officer compensation is not binding on the company. However, we and our Board will take into account the result of the vote when determining future executive compensation arrangements.
The affirmative vote of the holders of a majority in voting power of the shares of our common stock which are present in person or represented by proxy and entitled to vote thereon is required to approve the say-on-pay resolution set forth above. If your shares are held through a broker, bank, or other nominee and you do not vote your shares, your bank, broker, or other nominee may not vote your shares in this proposal. Assuming a quorum is present, broker non-votes or the failure to vote – either by not returning a properly executed proxy card or not voting in person at the annual meeting – will have no effect on the outcome of the voting on this proposal. Abstentions will have the same effect as a vote against the proposal. Unless instructed to the contrary in the proxy, the shares represented by the proxies will be voted “FOR” the proposal to approve, on an advisory basis, the compensation of the company’s named executive officers, as set forth in the company’s 2015 proxy statement.

Annual Meeting Information


vote.jpg
Voting in Person at the Annual Meeting. If you attend the annual meeting and wish to vote in person, you will be given a ballot at the annual meeting. Please note, however, that if your shares are held in street name by a broker, bank, or other nominee and you wish to vote at the annual meeting, you must bring to the annual meeting a proxy from the record holder of the shares authorizing you to vote at the annual meeting. Submitting your vote by proxy will not affect your right to attend the annual meeting and to vote in person.
revoke.jpg
Revoking Your Proxy or Your Voting Instructions to Your Proxy Holders. If you are a record holder of our common stock, you can change your vote at any time before your proxy is voted at the annual meeting by again voting by one of the methods described above or by attending the annual meeting and voting in person. You also may revoke your proxy by delivering a notice of revocation to our corporate secretary at NorthWestern Corporation, 3010 West 69th Street, Sioux Falls, South Dakota 57108, prior to the vote at the annual meeting. If your shares are held in street name, you must contact your broker, bank, or other nominee to revoke your proxy.
Quorum
At the close of business on the record date, there were 48,335,246 shares of NorthWestern Corporation common stock outstanding and entitled to vote at the annual meeting. Each outstanding share is entitled to one vote.
A quorum, which is a majority of the outstanding shares as of the record date, is necessary to hold a valid annual meeting. A quorum will be present at the annual meeting if the holders of a majority of the shares of our common stock outstanding and entitled to vote on the record date are present in person or represented by proxy. If a quorum is not present at the annual meeting, we expect that the annual meeting will be adjourned to solicit additional proxies.
Broker Non-Votes
Under the rules of the New York Stock Exchange (NYSE), certain shareholder nominees (such as brokers) have the discretion to vote shares on routine matters, such as the ratification of the appointment of our independent registered public accounting firm, when they do not receive voting instructions from the beneficial owner. They do not have authority to vote on non-routine matters (such as the election of directors, the advisory vote to approve named executive officer compensation, and the advisory vote on the frequency of advisory votes on executive compensation) unless they receive instruction from the beneficial owner.
A “broker non-vote” occurs when your broker submits a proxy for your shares but does not indicate a vote for a particular proposal because the broker does not have authority to vote on that proposal and has not received voting instructions from you. Broker non-votes are not counted as votes for or against the proposal in question or as abstentions, and are not counted to determine the number of votes present for the particular proposal.
Under the rules of the NYSE, if your broker holds shares in your name and delivers this proxy statement to you, the broker is entitled to vote your shares on Proposal 2 — Ratification of Independent Registered Public Accounting Firm even if the broker does not receive voting instructions from you. Without your instructions, the broker is not entitled to vote your shares on Proposal 1 — Election of Directors, Proposal 3 — Advisory Vote to Approve Named Executive Officer Compensation, or Proposal 4 — Advisory Vote to Approve Frequency of Advisory Votes on Executive Compensation. We encourage you to provide instructions to your broker, bank, or other nominee. This ensures your shares will be voted at the annual meeting.
Required Vote and Method of Counting
The required vote and method of counting votes for the various business matters to be considered at the annual meeting are described in the table on the following page. If you sign and return your proxy card without indicating your vote, your shares will be voted “FOR” each of the nominees for director, “FOR” ratification of Deloitte & Touche LLP as our independent registered public accounting firm, “FOR” the advisory vote to approve named executive officer compensation, for every “1 YEAR” on the advisory vote on the frequency of advisory votes on executive compensation and in accordance with the recommendations of our Board on any other matters properly brought before the annual meeting for a vote.

Householding; Receipt of Multiple Notices
Under the rules of the SEC, a single Notice of Internet Availability of Proxy Materials or set of annual reports and proxy statements may be sent to any household at which two or more shareholders reside if they appear to be members of the same family. Each shareholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information shareholders receive and reduces mailing and printing expenses. In accordance with a notice sent to certain shareholders who shared a single address, only one annual report and proxy statement were sent to that address unless any shareholder at that address requested that multiple sets of documents be sent. However, if any shareholder who agreed to householding wishes to receive a separate annual report or proxy statement for 2017 or in the future, he or she may telephone toll-free (800) 542-1061 or write to Broadridge Householding Department, 51 Mercedes Way, Edgewood, NY 11717, and the company will deliver promptly upon such written or oral request a separate Notice of Internet Availability of Proxy Materials or annual report or proxy statement. Shareholders sharing an address who wish to receive a single set of reports may do so by contacting their banks, brokers, or other nominees, if they are beneficial holders, or by contacting Broadridge at the address set forth above, if they are record holders.
Available Information
We file annual, quarterly, and current reports, proxy statements and other information with the SEC. These filings are available through a website maintained by a third-party and accessible through our company website at NorthWesternEnergy.comunder Our Company / Investor Relations / SEC Filings.
Our public filings also are available to the public from document retrieval services and the website maintained by the SEC at www.sec.gov.
