Attending the Annual Meeting will not in and of itself revoke a proxy.

A majority of the outstanding shares of common stock, present in person or represented by proxy, will constitute a quorum at the Annual Meeting. The inspectors of election appointed for the Annual Meeting will determine whether or not a quorum is present. Abstentions are counted for purposes of determining whether a quorum is present.

The following chart givesprovides information aboutregarding all nominees (each of whom has consented to being named in the Proxy Statement and to serving, if elected).

Vote Required

In order to be elected, a nominee must receive more votes cast in favor of his or her election than against election. Abstentions by those present or represented by proxy will not be counted as a vote cast either “for” or “against” with respect to the election of directors and, therefore, will have no effect on the outcome. Brokers will not have discretionary authority to vote on the election of directors. Accordingly, there could be brokernon-votes which will have no effect on the vote.

Under our Corporate Governance Guidelines, each nominee will tender a conditional resignation prior to the Annual Meeting, effective only if both (a) the votes “against” a nominee’s election exceed the votes “for” election (a “failedre-election”) and (b) such resignation is subsequently accepted by the Board. Any failedre-election will be referred to the Nominating and Governance Committee, which will make a recommendation to the Board as to whether to accept or reject the resignation. The Board will make a determination and publicly disclose its decision, the rationale for the decision and the directors who participated in the process within 90 days after the election. The Board expects the director who has had a failedre-election to abstain from participating in the Nominating and Governance Committee or Board discussion or vote regarding whether to accept his or her resignation offer. A director who has had a failedre-election may participate in discussions or votes with respect to other directors who have had a failedre-election.

Under our Corporate Governance Guidelines, a majority of the Board must be comprised of “independent directors.” In order to assist the Board in making its determination of director independence, the Board has adopted categorical standards of independence consistent with the standards contained in Section 303A.02 of the NYSE Listed Company Manual. The Board also has adopted an additional independence standard providing that a director who is an executive officer or director of a company that receives payments from the Company in an amount which exceeds 1% of such other company’s consolidated gross revenues is not “independent” until three years after falling below such threshold. A copy of our Corporate Governance Guidelines is posted on our website athttps://www.nisource.com/investors/governance.

The Board has affirmatively determined that, with the exception of Mr. Hamrock, all of the members of the Board and all nominees are “independent directors” as defined in Section 303A.02 of the NYSE Listed Company Manual and meet the additional standard for independence set by the Board.

Policies and Procedures with Respect to Transactions with Related Persons

Under the Company’s Code of Business Conduct, the following situations may present a conflict of interest and must be reviewed by the Nominating and Governance Committee to determine if they involve a direct or indirect interest of any director, executive officer or employee (including immediate family members) or otherwise present a conflict of interest:

Related person transactions are annually reviewed and, if appropriate, ratified by the Nominating and Governance Committee. Directors, individuals subject to Section 16 (“Section 16 Officer(s)”) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and senior executive officers are expected to raise any potential transactions involving a conflict of interest that relate to them with the Nominating and Governance Committee so that they may be reviewed in a prompt manner.

In addition, Jim L. Stanley doesdid not have direct responsibility for directing or reviewing his son’s work and doesdid not have influence over his employment at the Company. The Nominating and Governance Committee reviewed and approved this employment relationship.

Senior management regularly provides reports on our risks to the Board, the Audit Committee and the Board committees that oversee the applicable risks. Additionally, the Audit Committee discusses with management and the independent auditor the effect of regulatory and accounting initiatives on the Company’s financial statements and is responsible for review and evaluation of the Company’s major risk exposures, including cyber security and supplier risks, and the steps management has taken to monitor and control such exposures. The Audit Committee reviews and assesses the adequacy of the Company’s Risk Management Committee Charter annually, amending it as appropriate.

Director Selection Process.The Nominating and Governance Committee identifies and screens candidates for director and makes its recommendations for director to the Board. At times the Board may establish an ad hoc search committee to assist the Nominating and Governance Committee in this process. Additionally, the Nominating and Governance Committee has the authority to retain a search firm to help it identify director candidates to the extent it deems necessary or appropriate. In 2015, the Board established a search committee to assist the Nominating and Governance Committee and the Board in identifying qualified director candidates. In 2016,2017, the Nominating and Governance Committee also engaged the firm of Heidrick & Struggles International, Inc., which firm recommended Mr. AltabefButler for director. In considering candidates for director, the Nominating and Governance Committee considers the skills, expertise, experience and qualifications that will best complement the overall mix of skills and expertise of the Board in view of the strategy of, and the risks and opportunities faced by the Company, as well as each candidate’s relevant business, academic and industry experience, professional background, age, current employment, community service, other board service and other factors. In addition, the Nominating and Governance Committee takes into account the racial, ethnic and gender diversity of the Board.Board and actively seeks minority and female candidates.

For information on how to nominate a person for election as a director at the 20182019 Annual Meeting, please see the discussion under the heading “Stockholder Proposals and Nominations for 20182019 Annual Meeting.”

Board Evaluation Process.    The Nominating and Governance Committee oversees the self-evaluation process, which is used by the Board and by each committee of the Board to determine effectiveness and identify opportunities for improvement. Annually at its meeting in March, the Nominating and Governance Committee initiates the self-evaluation process and approves the form of written evaluation questionnaires that are distributed to each director for completion. The written evaluation questionnaires are updated each year as necessary to reflect changes identified in the prior year, any committee charter changes and any suggestions from the directors. The questionnaires solicit feedback on Board composition, Board meeting mechanics including information received, core responsibilities, relationship with management, committee functioning and other relevant matters. The Chief Legal Officer compiles and summarizes the responses for discussion at the subsequent Board and committee meetings. In addition, on an ongoing basis, the Chairman meets with each director individually to solicit feedback with respect to both the full Board and any committee on which the director serves, in addition to director performance and Board dynamics. Our Board utilizes the results of these evaluations in making decisions on Board agendas, Board structure, committee responsibilities and agendas, information presented to the Board, and continued service of individual directors on the Board. This information is then shared with the Board, and appropriate actions or changes are then identified.

No Mandatory Retirement Age or Term Limits.    Our Corporate Governance Guidelines set forth that we do not believe that mandatory retirement ages or term limits serve the needs of the Company. The Board periodically evaluates the performance and qualifications of individual directors in connection with the nomination process. In addition, although the Nominating and Governance Committee will consider length of service in recommending candidates forre-election, the Board does not believe that adopting a set term limit for directors serves the interests of the Company. Such limits may result in the loss of contributions from directors who have been able to develop, over a period of time, increasing insight into the Company, its operations and its strategic direction. The Nominating and Governance Committee reviews these policies as part of its annual governance review and will consider modifications to these policies as deemed necessary and in the best interests of the Company.

DIRECTOR COMPENSATION

Director Compensation.This section describes compensation for ournon-employee directors. To attract and retain highly qualified candidates to serve on the Board, we provide a combination of cash and equity awards. Ournon-employee director compensation is reviewed annually by our Nominating and Governance Committee with the assistance of the independent executive compensation consultant. The Nominating and Governance Committee with the assistance of Exequity LLP.LLP reviewed the amount and composition of director

compensation for 2017 and recommended an increase of $10,000 in the value of the equity portion of the annual retainer we provide to ournon-employee directors, which was implemented. A full-time employee who serves as director does not receive any additional compensation for service on the Board. Consequently, because Mr. Hamrock is also our President and CEO, he does not receive additional compensation for his service as a Board member.

Eachnon-employee director receives an annual retainer of $210,000,$220,000, consisting of $90,000 in cash and an award of restricted stock units valued at $120,000$130,000 at the time of the award. The cash retainer is paid in arrears in four equal installments at the end of each calendar quarter.

The restricted stock units are awarded annually, and the number of restricted stock units is determined by dividing the value of the grant by the closing price of our common stock on the grant date. Restricted stock units are granted tonon-employee directors under the NiSource Inc. 2010 Omnibus Incentive Plan (“Omnibus Plan”), which was approved by the stockholders on May 11, 2010, andre-approved for Code Section 162(m) purposes on May 12, 2015.

Additionally, eachnon-employee director who serves as chair of a Board committee receives compensation for this responsibility. The annual committee chair fees are $20,000 for each of the standing committees. The

Chairman of the Board receives additional annual compensation of $160,000 for his role and the Vice Chairman of the Board receives additional annual compensation of $75,000 for his role. These fees are paid in cash in arrears in four equal installments and are prorated in the case of partial year service.

All Other Compensation.The other compensation included under the column “All Other Compensation” in the Director Compensation Table below consists of matching contributions made by the NiSource Charitable Foundation.

Omnibus Plan.    The Omnibus Plan permits equity awards to be made tonon-employee directors in the form of incentive and non-qualified stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares, performance units, cash-based awards and other stock-based awards. Except as provided below, terms and conditions of awards tonon-employee directors are determined by the Board prior to grant. Since May 11, 2010, awards to directors have been made under the Omnibus Plan. Awards of restricted stock units associated with periods prior to June 1, 2011, vested immediately, but are not distributed in shares of common stock until after the director separates from the Board. Awards of restricted stock units made after June 1, 2011, vest and are payable in shares of our common stock on the earlier to occur of: (a) the last day of the director’s annual term for which the restricted stock units are awardedawarded; or (b) the date that the director separates from service due to a “Change-in-Control”“Change-in-Control” (as defined in the Omnibus Plan); provided, however, that effective in 2015, any director that commences services after the start of an annual term vests on the first anniversary of the initial grant; and, provided further, that in the event that the director separates from service prior to such time as a result of “Retirement” (defined as the cessation of services after providing a minimum of five continuous years of service as a member of the Board), death or “Disability” (as defined in the Omnibus Plan), the director’s restricted stock unit awards shall pro rata vest in an amount determined by using a fraction, where the numerator is the number of full or partial calendar months elapsed between the grant date and the date of the director’s Retirement, death or Disability, and the denominator of which is the number of full or partial calendar months elapsed between the grant date and the last day of the director’s annual term for which the director is elected that corresponds to the year in which the restricted stock units are awarded. All equity awards under our Omnibus Plan, including awards tonon-employee directors have a minimum vesting term of one year unless the director separates from service prior to such time as the result of Retirement, death or Disability. The vested restricted stock units awarded on or after June 1, 2011, are payable as soon as practicable following vesting, unless otherwise provided pursuant to any prior election thenon-employee director may have made to defer distribution. All equity awards under our Omnibus Plan, including awards to non-employee directors have a minimum vesting term of one year. With respect to restricted stock units that have not been distributed, additional restricted stock units are credited to eachnon-employee director to reflect dividends paid to stockholders on common stock. The restricted stock units have no voting or other stock ownership rights and are payable in shares of our common stock upon distribution.

Director Stock Ownership.    The Board maintains stock ownership requirements for its directors that are included in the Corporate Governance Guidelines. Within five years of becoming anon-employee director, eachnon-employee director is required to hold an amount of Company stock with a value equal to five times the annual cash retainer paid to directors by the Company. Company stock that counts towards satisfaction of this

requirement includes shares purchased on the open market, awards of restricted stock or restricted stock units through the priorNon-Employee Director Stock Incentive Plan or Omnibus Plan, and shares beneficially owned in a trust or by a spouse or other immediate family member residing in the same household. All of thenon-employee director nominees are in compliance with the stock ownership requirements that are included in the Corporate Governance Guidelines.

Each director has a significant portion of his or her compensation directly aligned with long-term stockholder value. Fifty-sevenFifty-nine percent (57%(59%) of anon-employee director’s 20162017 annual retainer (valued as of the time of award) consisted of restricted stock units, which are converted into common stock when vested and distributed to the director.

Our Executive Compensation Philosophy

The key design priorities of the Company’s 2017 executive compensation program arewere to:

– Attract and retain executives with competitive compensation opportunities;

– Motivate and reward executives for achieving and exceeding our business objectives;

– Ensure that substantialsignificant portions of pay remain at risk for failure to achieve our business objectives;

The Compensation Committee believes that the Company’s executive compensation program is thoughtfully and effectively constructed to fulfill our compensation objectives and rewards decision makingreward effective leadership decisions that createscreate value for our stockholders, customers and other key stakeholders.

Principal ElementsOverview of Our 20162017 Executive Compensation Program

We have designeddesign our executive compensation program to meetattract, retain and motivate highly-qualified executive talent. We believe highly-qualified executive talent is an essential driver of the Company’s success in achieving its business objectives.

The principal elements of compensation that we provide to our business objectives using various compensation elements intended to drive bothexecutives including the Named Executive Officers are: base salary, annual short-term performance-based cash incentives and long-term performance.performance-based equity incentive awards. We use short- and long-term performance-based compensation to motivate our executives to meet and exceed the Company’s short- and long-term business objectives.

Our long-term performance-based compensation is denominated entirely in common shares to align the interests of executives with those of our stockholders. The principal elements of our 2017 total compensation program, time horizon and design objectives of each element are shown below.

We generally target total compensation (base salary, annual short-term performance-based cash incentives and long-term equity incentive awards) to be competitive with the compensation paid to similarly positioned executives at companies within our peer group of companies (the “Comparative Group”) as described in the section entitled “Our Executive Compensation Process — Competitive Market Review.” We do not, however, manage pay to a stipulated percentile of the Comparative Group practices.

When making decisions about our executive compensation program, the Compensation Committee takes into account the stockholders’ view of such matters. In 2017, over 96% of the votes cast by our investors were voted in favor of ourSay-on-Pay Proposal at our 2017 annual meeting of stockholders. No changes were made to the design of our executive compensation program in response to the 2017 stockholder vote.

Our Executive Compensation Mix

We believe that a significant percentage of total compensation for ourthe Named Executive Officers should consist ofat-risk, performance-based compensation. The Compensation Committee believes the appropriate mix of compensation elements should take into account the Company’s financial and strategic objectives, the competitive environment, retentive elements, Company performance, individual performance and responsibilities, and evolving governance practices.

The following charts illustrate the extent to which 20162017 target total compensation for our CEO and our other Named Executive Officers was payable in fixed (base salary) and performance-contingent (annual performance-based cash incentive payable at the target level and the grant date fair value of the annual long-term performance-based equity incentive award payable at the target level) formats.

We believe that the principal elements of our total compensation for 2016, as more fully described below, help us achieve the objectives of our compensation program as follows:

Base Salary

Base salary is designed to provide our employees with a level of fixed pay that is commensurate with the employee’s role and responsibility. We believe that by delivering base salaries that are reflective of market norms, the Company is well-positioned to attract, retain and motivate top caliber executives in an increasingly competitive labor environment. The Compensation Committee annually reviews the base salaries of the Company’s senior executives, including the Named Executive Officers, to evaluate whether they are competitive within our industry. In reviewing the base salaries, the Compensation Committee considers the base salaries paid to similarly situated executives by the companies in the Comparative Group. See the section entitled “Our Executive Compensation Process — Competitive Market Review.”

The Compensation Committee determines any base salary changes for the Company’s senior executives, including the Named Executive Officers, based on a combination of factors that includes competitive pay standards, level of responsibility, experience, internal equity considerations, historical compensation, and individual performance and contribution to business objectives, as well as recommendations from Mr. Hamrock, our CEO. Mr. Hamrock’s pay is evaluated separately by the Compensation Committee, taking into account those factors reviewed for all other senior executives.executives other than the recommendation from Mr. Hamrock. The Compensation Committee then provides their recommendation regarding CEO compensation to the independent members of the Board for approval. See the section below entitled “Compensation Committee Actions Related to 2016 Compensation”2017 Compensation – 2017 Base Salaries” for more information.

Annual Performance-Based Cash Incentive Plan (“Cash Incentive Plan”)

This component of total compensationThe Cash Incentive Plan provides our employees, including the Named Executive Officers, with the opportunity to earn a cash award tied to both the Company’s performance and their individual contributions to the organization’sCompany’s success. Annual cash incentives are authorized byAwards to our senior executives, including the Omnibus Plan which was originally approved by stockholders in May 2010 and re-approved by stockholders for Code Section 162(m) purposes in May 2015. AwardsNamed Executive Officers, under the Cash Incentive Plan are subject to one corporate financial performance goal with additional(weighted at 75%) and several operational goals related to customer care and safety.safety (weighted at 25%). The financial performance goal is based on the Company’s financial plan, which is approved by the Board at the beginning of the year, and is designed to achieve the Company’s aimgoal of creating sustainable stockholder value by growing earnings and providing a strong dividend. The customer care and safety goals are designed to incent achievement of our business imperatives.

Eligibility for participation in the Cash Incentive Plan extends to nearly all Company employees. Every eligible employee has an incentive opportunity at trigger, target and stretch levels of performance, and the Compensation Committee identifies expectations for all senior executives, including the Named Executive Officers and the CEO, for whom the Compensation Committee makes recommendations for consideration by the independent members of the Board. See the section below entitled “Compensation Committee Actions Related to 2016 Compensation—Annual Performance-Based2017 Compensation — 2017 Cash Incentives”Incentive Plan” for more information regarding the 20162017 Cash Incentive Plan, including incentive opportunities, performance measures and weightings, goals and payouts for each of the Named Executive Officers.

Long-Term Equity Incentive Plan (“LTIP”)

Our compensation program also includesThe LTIP provides our executives, including the Named Executive Officers, with the opportunity to earn shares of Company stock tied to Company performance. The 2017 LTIP awards consist solely of performance shares that vest based on the achievement of two goals over a long-term equity incentive component.three year performance period: cumulative net operating earnings per share (weighted at 50%) and relative total shareholder return (weighted at 50%). The Compensation Committee believes it is important that each executive in particular each of our senior executives, has personal financial exposure to the performance of the Company’s stock and, therefore, is aligned with the financial interests of stockholders. The Compensation Committee also believes that long-term equity incentives promote decision making that is consistent with the Company’s long-term business objectives.

Since 2011, the Compensation Committee has delivered annual long-term equity incentive awards solely in a performance-contingent format to further align our executives’ interests with those of our stockholders and the Company’s long-term business objectives. The sole exception to this practice was in 2015 when service-based awards were granted in connection with the Separation. In January 2016, the Compensation Committee reverted to its historical practice of delivering annual long-term equity incentive awards solely in performance shares that vest based on the achievement of multi-year performance goals and the executive’s continued employment through the vesting date, subject to special vesting rules that apply in the event of death, “Retirement,” “Disability” or a “Change-in-Control” (each as defined in the Omnibus Plan). Termination for any other reason prior to the vesting date will result in forfeiture of all related performance shares. Additionally, the Omnibus Plan prescribes a minimum vesting period of one year for all equity awards.

When establishing equity award opportunity levels for eachsenior executives, including the Named Executive Officer,Officers, the Compensation Committee considers, among other things, the executive’s base salary, the appropriate mix of cash and equity award opportunities, prior awards under the LTIP and the compensation practices for similarly situated executives at other companies in our Comparative Group. The actual value of each performancethe 2017 LTIP award, if any, dependswill depend upon Company performance againstpre-established performance measures as well as the Company’s stock price at the time the award isawards are settled.

The Compensation Committee may also approve special equity awards that are not performance-based to attract and retain executive talent or to recognize significant contributions.table below summarizes key features of the 2017 LTIP awards. See the section below entitled “Compensation Committee Actions Related to 20162017 Compensation” for more information regarding the 20162017 LTIP awards for each of the Named Executive Officers, including a special sign-on equity grant to Mr. Vegas and the performance measures and goals for the 2016 performance share awards.Officers.

Other Compensation and Benefits

We also provide other forms of compensation and benefits to our senior executives, including the Named Executive Officers, consisting of severance andchange-in-control arrangements, an executive deferred compensation plan, a limited number of perquisites severance and change-in-control arrangements and a number of other employee benefits that generally are extended to our entire employee population. These other forms of compensation and benefits are generally comparable to those that are provided to similarly situated executives at other companies of our size.size and thereby serve the objectives of our compensation program to attract and retain our executives.

We maintain an executive severance policy andChange-in-Control Agreements with each of the Named Executive Officers.Change-in-Control Agreements are intended to ensure that thoroughly objective judgments are made in relation to any potential change in corporate ownership so that stockholder value is appropriately safeguarded and returns to investors are maximized. TheChange-in-Control Agreements provide for cash severance benefits upon a double-trigger (meaning there must be both a qualifyingchange-in-control and termination of employment) and do not provide for any“gross-up” payments to executives for excise taxes incurred with respect to benefits received under aChange-in-Control Agreement. Additionally, the Omnibus Plan provides for double-trigger vesting for equity awards that are assumed or replaced by an acquiring company upon achange-in-control; meaning that there must be both achange-in-control and a qualifying termination of employment in order for the equity awards to vest in connection with or following suchchange-in-control. In the event equity awards are not assumed or replaced in achange-in-control, then the outstanding equity awards will vest upon the occurrence of achange-in-control alone. For further information regarding the benefits to be received upon termination of employment orchange-in-control, see the table in the section entitled “Potential Payments upon Termination of Employment or aChange-in-Control of the Company” and the accompanying narrative.

In connection with Mr. Stanley’s announced retirement, the Company eliminated the position of COO and realigned Mr. Stanley’s prior responsibilities among other executive officers. As consideration for Mr. Stanley’s agreement to remain employed with the Company to assist with the transition of his roles through his June 1, 2017 separation date and in exchange for a release of claims in favor of the Company, Mr. Stanley was provided separation benefits generally consistent with a position elimination under the Company’s Executive Severance Policy. Mr. Stanley received: (i) a lump sum payment of $550,000; (ii) a payout under the 2017 cash incentive plan as detailed under “2017 Cash Incentive Plan,” based on actual performance during the year; (iii) a payout equivalent to the cost of 130% of twelve months of COBRA premiums; and (iv) a payout of accrued and unused vacation time. All payments provided to Mr. Stanley are shown in the Summary Compensation Table and are detailed in the table under the section entitled “Potential Payments upon Termination of Employment or aChange-in-Control of the Company.”

Perquisites

Perquisites are not a principal element of our executive compensation program. They are intended to assist executive officersexecutives in the performance of their duties on the Company’s behalf or to otherwise provide benefits that have a combined personal and business purpose. Generally, the Company does not reimburse the Named Executive Officers for the payment of personal income taxes incurred by the executivesthey incur in connection with their receipt of these benefits, except for relocation expenses, consistent with Company practice for all employees who receive Company-paid relocation expenses. For information regarding 20162017 perquisites, see the 20162017 Summary Compensation Table and footnote (6) to that table.

Deferred Compensation Plan

We also maintain the Executive Deferred Compensation Plan (the “Deferred Compensation Plan”) through which eligible Company executives, including the Named Executive Officers, may elect to defer between 5% and

80% of their base salary and annual cash incentive payout. The Company makes the Deferred Compensation Plan available to eligible executives so they have the opportunity to defer their cash compensation without regard to the limits imposed by the IRS for amounts that may be deferred under the 401(k) Plan. The material terms of the Deferred Compensation Plan are described in the narrative to the 2016 2017Non-qualified Deferred Compensation Table.

Pension Programs

During 2017, we maintained atax-qualified defined benefit pension plan for essentially all salaried exempt employees hired before January 1, 2010, allnon-exempt employees (bothnon-union and certain union employees) hired before January 1, 2013, as well as for other union employees, regardless of hire date, and anon-qualified defined benefit pension plan (the “Pension Restoration Plan”) for all eligible employees with annual compensation or pension benefits in excess of the limits imposed by the Internal Revenue Service (“IRS”), including any eligible Named Executive Officer. The Pension Restoration Plan provides for a pension benefit under the same formula provided under thetax-qualified plan but without regard to the IRS limits and reduced by amounts paid under thetax-qualified plan. The material terms of the pension programs are described in the narrative to the 2017 Pension Benefits Table.

Savings Programs

The Named Executive Officers are eligible to participate in the sametax-qualified 401(k) Plan as most employees and in anon-qualified defined contribution plan (the “Savings Restoration Plan”) maintained for eligible executive employees. The 401(k) Plan includes a Company match that varies depending on the pension plan in which the employee participates and a Company profit sharing contribution for most employees of between 0.5% and 1.5% of the employee’s eligible earnings based on achievement of the overall corporate net operating earnings per share measure. In addition, for salaried employees hired after January 1, 2010, andnon-unionnon-exempt employees hired after January 1, 2013, the 401(k) Plan includes a 3% Company contribution to the employee accounts. The Savings Restoration Plan provides for Company contributions in excess of IRS limits under the 401(k) Plan for eligible employees, including the Named Executive Officers. The material terms of the Savings Restoration Plan are described in the narrative to the 2017Non-qualified Deferred Compensation Table.

Health and Welfare Benefits

We also provide other broad-based benefits such as medical, dental, life insurance and long-term disability coverage on the same terms and conditions to all employees, including the Named Executive Officers. We believe that these broad-based benefits enhance the Company’s reputation as an employer of choice and thereby serve the objectives of our compensation program to attract, retain and motivate our employees.choice.

Our Executive Compensation Process

The Compensation Committee is responsible for determining salaries, performance-based incentives and other matters related to the compensation of our executives and for overseeing the administration of our equity plans, including equity award grants to our executive officers. In doing so, the Compensation Committee apprises the Board with respect to the evaluation, compensation and benefits of our executives. The Compensation Committee takes into account various factors when making compensation decisions, including:

The Compensation Committee reviews the compensation of our CEO and his executive direct reports each year. For our CEO, the Compensation Committee evaluates CEO performance in light of the Company’s goals and objectives and considers recommendations from the Compensation Committee’s independent executive

compensation consultant Exequity LLP, that are reflective of the Compensation Committee’s assessment of our CEO’s performance and compensation competitiveness. Following this evaluation, the Compensation Committee submits its recommendations to the independent members of the Board for review and approval.

Competitive Market Review

In connection with its compensation decision making, the Compensation Committee reviews the executive compensation practices in effect at other companies in the Comparative Group. These companies comprised leading gas, electric, and combination utilities that were selected by the Compensation Committee for their operational comparability to the Company and because we generally compete with these companies for the same executive talent. For 2016,2017, the Compensation Committee, with input from its independent compensation consultant, Exequity LLP, removed EQT Corporation, Pepco Holdings, Inc., Spectra Energy Corp., and The Williams Companies, Inc. frommade no change to the Comparative Group and added Alliant Energy Corporation, Atmos Energy Corporation,compensation peer group, except to reflect The Laclede Group, Inc., OGE Energy Corp., One Gas,’s name change to Spire, Inc., Piedmont NaturalDominion Resources, Inc.’s name change to Dominion Energy, Inc. and the mergers of AGL Resources Inc. into Southern Company Gas Company,and Questar Corporation into Dominion Energy, Inc., PNM Resources, Inc., Vectren Corporation and WEC Energy Group, Inc. These changes were made to further align the Company with its peer companies with respect to revenue size, market capitalization and operational similarity. For purposes of evaluating 20162017 compensation practices, the Comparative Group included the following companies:

⁽¹⁾The Compensation Committee selected the 2017 Compensation Peer Group in October 2016 based on fiscalyear-end 2015 revenue and market capitalization data. Fiscalyear-end revenue and market capitalization data was compiled by the Committee’s independent compensation consultant.

Compensation Committee Actions Related to 2017 Executive Compensation

During 2017, the Compensation Committee reviewed and, as appropriate, took action with respect to each element of total compensation for each Named Executive Officer following the principles, practices and processes described above. The Compensation Committee’s compensation determinations and recommendations were based primarily upon recognition of the roles, responsibilities and performance of each Named Executive Officer, a review of the Comparative Group and an assessment that the total compensation provided to each Named Executive Officer offered well-balanced incentives to focus on serving the interests of the Company and its stockholders.

2017 Base Salaries

The Compensation Committee annually reviews the base salaries of senior executives, including the Named Executive Officers, to evaluate whether they are competitive and appropriately reflect performance. In January 2017, the Compensation Committee considered the base salaries earned by similarly situated executives of companies in the Comparative Group, responsibilities, experience, internal pay equity, historical compensation practices, individual performance and contributions to achievement of business objectives. The Compensation Committee approved salary increases for Mr. Brown and Ms. Sistovaris to maintain salary level market competitiveness for each executive that is reflective of strong performance and their significant achievements in their roles as CFO and Executive Vice President and President of NIPSCO, respectively. With respect to Mr. Hamrock, the Compensation Committee recommended to the independent members of the Board an increase in base salary level to maintain market competitiveness that is reflective of his strong performance and significant achievements in his role as President and CEO of the Company. The independent members of the Board considered and approved the recommendation of the Compensation Committee.

Subsequently, the Compensation Committee approved an increase for Mr. Vegas effective on May 1, 2017, due to his assumption of additional responsibilities and promotion to Executive Vice President, Gas Business Segment and Chief Customer Officer.

The 2017 base salary adjustments for Messrs. Hamrock and Brown and Ms. Sistovaris were effective on June 1, 2017 and Mr. Vegas’ salary increase became effective on May 1, 2017. All 2017 increases in Named Executive Officer salaries are shown in the table below. No other Named Executive Officer received an increase in 2017.

2017 Cash Incentive Plan

In January 2017, the Compensation Committee established performance measures and goals to be used to determine the 2017 Cash Incentive Plan payouts for all of our employees, including the Named Executive Officers. In determining Cash Incentive Plan opportunities for the Named Executive Officers, the Compensation Committee considered competitive information from the Comparative Group, input from the independent compensation consultant, historical payouts and individual performance in its review of the trigger, target and stretch opportunities for Named Executive Officers and made no changes to the trigger, target and stretch opportunities for Named Executive Officers, except for Mr. Hamrock. With respect to Mr. Hamrock, the Compensation Committee recommended to the independent members of the Board an increase in his target and stretch incentive opportunity. The Compensation Committee recommended this increase along with an increase to his base salary, as noted above, and long-term incentive, as noted below, in order to further align his compensation with other chief executive officers within the Comparative Group, reward his strong performance and maintain market competitiveness. The independent members of the Board considered and approved the recommendation of the Compensation Committee.

Subsequently, the Compensation Committee increased each of the trigger, target and stretch incentive opportunities for Mr. Vegas, effective on May 1, 2017, due to his assumption of increased responsibilities and promotion to Executive Vice President, Gas Business Segment and Chief Customer Officer. The Compensation Committee determined Mr. Vegas’ Cash Incentive Plan opportunities should be adjusted in addition to his base salary, as noted above, and long-term incentive as noted below, to reflect the increased responsibilities and to maintain competitiveness with other similarly positioned executives within the Comparative Group for his new role as Executive Vice President, Gas Business Segment and Chief Customer Officer.

All 2017 increases to Named Executive Officer Cash Incentive Plan opportunities are shown in the table below. No other Named Executive Officer received an increase in 2017.

The 2017 Cash Incentive Plan awards for senior executives, including all of the Named Executive Officers, were subject to achievement with respect to one corporate financial goal, net operating earnings per share, as well as additional operational goals related to customer care and safety, as detailed in the table below. The Compensation Committee approved these measures for the performance period because they were deemed to be important to the Company’s success in increasing stockholder value. The incentive opportunities for the Named Executive Officers were contingent on achievement of goals relating to these measures, subject to final discretionary adjustments by the Compensation Committee.

The applicable performance measures and their associated weightings and results as a percentage of the target incentive opportunity for 2017 for each of the Named Executive Officers are shown in the table below.
