Proxy Statement

Governance Highlights
We are committed to strong corporate governance aligned with stockholder interests. The board, through its nominating and governance committee, regularly monitors leading practices in governance and adopts measures that it determines are in the best interests of the company and its stockholders.
■	Three new independent directors were added to the board during 2018 and 2019 with the retirement of three former directors, including the independent chair of the board.
■	Dennis W. Johnson, who previously served as chair of our audit committee, was elected as the new independent board chair in 2019.
■	The environmental and sustainability committee was established in 2019 as a standing committee of the board of directors to oversee environmental, workplace health, safety, and other social sustainability matters that fundamentally affect the company’s business and long-term viability.
■	In conjunction with the election of new directors, the appointment of Mr. Johnson as board chair, and the establishment of the environmental and sustainability committee, membership on the board’s standing committees was refreshed with new chairs appointed for each of the committees.
■	Membership of all committees consists entirely of independent directors.
■	The company was recognized, for the third consecutive year, by the 2020 Women on Boards campaign for diversity on the corporation’s board of directors.
■	The company was recognized by the Women’s Forum of New York as a 2019 Corporate Champion with at least 30% of board seats held by women.
■	On January 1, 2019, we completed a holding company reorganization to provide additional financing flexibility and further separation between the company’s utility and other business segments. As a result of the reorganization, all of the company’s utility operations are conducted through wholly-owned subsidiaries.

Business Performance Highlights
Our overall performance in 2019 was consistent with our long-term strategy as we focused on growing our regulated energy delivery and construction materials and services business segments. In addition to our 2019 financial performance highlighted on the next page:
■	The electric segment completed construction of the 345-kilovolt transmission line project from Ellendale, North Dakota, to Big Stone City, South Dakota, in February 2019.
■	The electric segment announced plans to retire three aging coal-fired electric generation units at two locations within the next two to three years and construct a new simple-cycle natural gas combustion turbine. The retirement of the 44-megawatt Lewis & Clark Station in Sidney, Montana is expected in early 2021 and the Heskett units 1 and 2, which combine for 100 megawatts, would be retired in early 2022. Subject to regulatory approval, a new 88-megawatt simple-cycle peaking unit at the Heskett Station would be constructed in 2023.
■	The construction materials and contracting segment had record revenues in 2019.
■	The construction materials and contracting segment completed the acquisition of Viesko Redi-Mix, Inc. in Wheatland, Oregon in 2019.
■	The construction materials and contracting segment also acquired aggregate reserves near Marble Falls, Texas in February 2019. In November 2019, the Texas Commission on Environmental Quality issued an Air Quality Standard Permit to construct a rock-crushing plant at the quarry. The quarry, which is expected to begin production in late 2020, contains an estimated 40-year supply of high quality aggregates enabling the construction materials and contracting segment to supply a significant portion of the base materials used for its local construction and production of ready-mixed concrete and asphalt along with third-party sales in our Texas market.
■	The pipeline and midstream segment in 2019 had record transportation volumes for the third consecutive year. The segment completed construction of its Demicks Lake Project in McKenzie County, North Dakota, and Phase I of the Line Section 22 Project near Billings, Montana came online. The projects are designed to increase capacity by 175 MMcf and 14.3 MMcf per day, respectively. Construction on Phase II of the Line Section 22 Project, which includes additional design capacity of 8.2 MMcf per day, is expected to be completed the first half of 2020. In February 2020, the segment also completed construction and placed into service the Demicks Lake Expansion Project which is designed to increase capacity by 175 MMcf per day.
■	The pipeline and midstream segment announced plans to construct approximately 62 miles of pipeline, compression, and ancillary facilities to transport natural gas from core Bakken production areas in western North Dakota to an interconnection point with another interstate transmission pipeline. This North Bakken Expansion Project, as designed, would provide 350 million cubic feet per day of natural gas transportation capacity with estimated completion in 2021.
■	The construction services segment had record revenues in 2019.
■	The construction services segment completed the acquisition of the assets of Pride Electric, Inc. in Redmond, Washington in 2019.

Proxy Statement

Key Features of Our Executive Compensation Program

What We Do
þ	Pay for Performance - Annual and long-term award incentives tied to performance measures set by the compensation committee comprise the largest portion of executive compensation.
þ	Independent Compensation Committee - All members of the compensation committee meet the independence standards under the New York Stock Exchange listing standards and the Securities and Exchange Commission rules.
þ	Independent Compensation Consultant - The compensation committee retains an independent compensation consultant to evaluate executive compensation plans and practices.
þ	Competitive Compensation - Executive compensation reflects executive performance, experience, relative value compared to other positions within the company, relationship to competitive market value compensation, business segment economic environment, and the actual performance of the overall company and the business segments.
þ	Annual Cash Incentive - Payment of annual cash incentive awards are based on business segment and overall company performance against pre-established annual financial measures.
þ	Long-Term Equity Incentive - Long-term incentive awards may be earned at the end of a three-year period based on achieving pre-established performance measures and are paid through performance shares which encourages stock ownership and helps retain management talent.
þ	Balanced Mix of Pay Components - The target compensation mix is not overly weighted toward annual incentive awards but rather represents a balance of annual cash and long-term equity-based compensation.
þ	Mix of Financial Goals - Use of a mixture of financial goals to measure performance prevents overemphasis on a single metric.
þ	Annual Compensation Risk Analysis - Risks related to our compensation programs are regularly analyzed through an annual compensation risk assessment.
þ	Stock Ownership and Retention Requirements - Executive officers are required to own, within five years of appointment or promotion, company common stock equal to a multiple of their base salary. Our president and chief executive officer is required to own stock equal to four times his base salary, and the other named executive officers are required to own stock equal to three times their base salary. The executive officers also must retain at least 50% of the net after-tax shares of stock vested through the long-term incentive plan for the earlier of two years or until termination of employment. Net performance shares must also be held until share ownership requirements have been met.
þ	Clawback Policy - If the company’s audited financial statements are restated due to any material noncompliance with the financial reporting requirements under the securities laws, the compensation committee may, or shall if required, demand repayment of some or all incentives paid to our executive officers within the last three years.
What We Do Not Do
ý	Stock Options - The company does not use stock options as a form of incentive compensation.
ý	Employment Agreements - Executives do not have employment agreements entitling them to specific payments upon termination or a change of control of the company.
ý	Perquisites - Executives do not receive perquisites that materially differ from those available to employees in general.
ý	Hedge Stock - Executives are not allowed to hedge company securities.
ý	Pledge Stock-Executives are not allowed to pledge company securities in margin accounts or as collateral for loans.
ý	No Dividends or Dividend Equivalents on Unvested Shares - We do not provide for payment of dividends or dividend equivalents on unvested share awards.
ý	Tax Gross-Ups - Executives do not receive tax gross-ups on their compensation except for circumstances regarding relocation.

Corporate Responsibility, Environmental, and Sustainability Highlights
MDU Resources Group, Inc. is Building a Strong America® by providing essential products and services to our customers with a long-term view toward sustainable operations. To ensure we can continue to provide these products and services in the communities where we do business, we recognize that we must preserve the trust our communities place in us to be a good corporate citizen. We remain committed to pursuing responsible corporate environmental and sustainability practices and to maintaining the health and safety of the public and our employees. In 2019 the board of directors established the environmental and sustainability committee as a standing committee of the board. The committee meets quarterly in conjunction with the regular meetings of the board. The committee oversees and provides recommendations to management and the board regarding environmental, workplace health, safety, and other social sustainability matters that fundamentally affect the company’s business interests and long-term liability. To better serve our investors and other stakeholders, in 2019 we began reporting environmental, social, governance, and sustainability (ESG/sustainability) metrics relevant and important to our operations in frameworks that provide our stakeholders more uniform and transparent data and information, allowing for comparison with our peers and other companies operating in our industries. For our electric and natural gas distribution segments, as well as our pipeline and midstream segment, we report ESG/sustainability metrics using the reporting templates developed by the Edison Electric Institute and the American Gas Association. For our other business segments, we report ESG/sustainability information under the framework developed by the Sustainability Accounting Standards Board (SASB) for our applicable industries. The use of the metrics developed by these organizations provides for ESG/sustainability reporting tailored to our industries. The reports can be found at www.mdu.com/sustainability. These are some highlights of our recent efforts regarding sustainability:
■	As our renewable generation resource capacity has increased, the carbon dioxide (CO2) emission intensity of our electric generation resource fleet has been reduced by approximately 31% since 2003. We expect it to continue to decline with the planned retirements of the Lewis & Clark and Heskett 1 and 2 coal generation facilities.
■	Renewable resources comprised approximately 27% of our current electric generation resource nameplate capacity.

■ Approximately 26.5% of the electricity delivered to our customers from company-owned generation in 2019 was from renewable resources.

■ We invested approximately $137 million in environmental emission control equipment and other environmental improvements at our coal-fired electric generation plants since 2013. The investments have resulted in substantial reductions in mercury, sulfur dioxide, nitrogen oxide, and filterable particulate emissions from our coal-fired electric generation resources.

■ Montana-Dakota Utilities Co. produces renewable natural gas (RNG) from the Billings Regional Landfill in Montana. The project came online at the end of 2010 and has produced approximately 1.23 million dekatherm of RNG through year-end 2019. The RNG is supplied to the vehicle fuel market generating renewable identification numbers (RINS) and low carbon fuel standard (LCFS) credits in California and Oregon. In calendar year 2019, the Billings Landfill Plant produced approximately 1.63 million RINs and 4,303 LCFS credits.

■ Our utility companies received high scores in customer satisfaction. Cascade Natural Gas Corporation ranked first nationwide for all gas utilities in the 2019 J.D. Power Gas Utility Residential Customer Satisfaction Study.^SM In addition, Cascade Natural Gas Corporation ranked first, Intermountain Gas Company second, and Montana-Dakota Utilities Co. third among West Region mid-sized natural gas utilities in the 2019 J.D. Power Gas Utility Residential Customer Satisfaction Study.^SM

■ Knife River Corporation produces and places warm-mix asphalt in applications where warm-mix asphalt is allowed. Warm-mix asphalt is produced at cooler temperatures than traditional hot-mix asphalt methods, which reduces the amount of fuel needed in the production process and thereby reduces emissions and fumes.

■ Knife River Corporation continued its practice of recycling and reusing building materials. This conserves natural resources, uses less energy, alleviates waste disposal problems in local landfills, and ultimately costs less for the consumer.

■ The MDU Resources Foundation awarded grants of $1.57 million to educational and nonprofit institutions in 2019. Since its incorporation in 1983, the foundation has contributed more than $35.5 million to worthwhile causes in categories of education, civic and community activities, culture and arts, environmental stewardship, and health and human services.

■ We encourage and support community volunteerism by our employees. The MDU Resources Foundation contributes a $500 grant to an eligible nonprofit organization after an employee volunteers a minimum of 25 hours to the organization during non-company hours during a calendar year. Eligible organizations are local 501(c) nonprofit organizations providing services in categories of civic and community activities, culture and arts, education, environment, and health and human services. In 2019, the foundation granted $60,000 under this program, matching over 7,900 employee volunteer hours.

■ We encourage support of educational institutions by all employees. The MDU Resources Foundation matches contributions to educational institutions by employees up to $750.

MDU Resources Group, Inc. Proxy Statement 13

Additional Information - Majority Voting

A majority of votes cast is required to elect a director in an uncontested election. A majority of votes cast means the number of votes cast “for” a director’s election must exceed the number of votes cast “against” the director’s election. “Abstentions” and “broker non-votes” do not count as votes cast “for” or “against” the director’s election. In a contested election, which is an election in which the number of nominees for director exceeds the number of directors to be elected and which we do not anticipate, directors will be elected by a plurality of the votes cast.

Unless you specify otherwise when you submit your proxy, the proxies will vote your shares of common stock “for” all directors nominated by the board of directors. If a nominee becomes unavailable for any reason or if a vacancy should occur before the election, which we do not anticipate, the proxies will vote your shares in their discretion for another person nominated by the board.

Our policy on majority voting for directors contained in our corporate governance guidelines requires any proposed nominee for re-election as a director to tender to the board, prior to nomination, his or her irrevocable resignation from the board that will be effective, in an uncontested election of directors only, upon:

• receipt of a greater number of votes “against” than votes “for” election at our annual meeting of stockholders; and

• acceptance of such resignation by the board of directors.

Following certification of the stockholder vote, the nominating and governance committee will promptly recommend to the board whether or not to accept the tendered resignation. The board will act on the nominating and governance committee’s recommendation no later than 90 days following the date of the annual meeting.

Brokers may not vote your shares on the election of directors if you have not given your broker specific instructions on how to vote. Please be sure to give specific voting instructions to your broker so your vote can be counted.

Board Evaluations and Process for Selecting Directors

In the annual board evaluation process, the nominating and governance committee evaluates our directors considering the current needs of the board and the company. In addition, during the year, the committee discusses board succession and reviews potential candidates. Although the committee may also retain a third party to assist in identifying potential nominees, none were retained in 2019.

Our annual board evaluation process involves assessments at the board and board committee levels. These annual evaluations are conducted by the chair of the nominating and governance committee and periodically by an independent third party.

Our governance guidelines provide that directors are not eligible to be nominated or appointed to the board if they are 76 years or older at the time of the election or appointment. Term limits on directors’ service have not been instituted.

Director Qualifications, Skills, and Experience

Director nominees are chosen to serve on the board based on their qualifications, skills, and experience, as discussed in their biographies, and how those characteristics supplement the resources and talent on the board and serve the current needs of the board and the company.

In making its nominations, the nominating and governance committee also assesses each director nominee by a number of key characteristics, including character, success in a chosen field of endeavor, background in publicly traded companies, independence, and willingness to commit the time needed to satisfy the requirements of board and committee membership. Although the committee has no formal policy regarding diversity, in recommending director nominees the committee considers diversity in gender, ethnic background, geographic area of residence, skills, and professional experience.

Board Composition and Refreshment

The nominating and governance committee is focused on ensuring that the board reflects a diversity of experience, skills, and backgrounds. Each of the current directors has been nominated for election to the board of directors upon recommendation by the nominating and governance committee and each has decided to stand for election.

With the retirement of former board members Harry J. Pearce and William E. McCracken at the 2019 annual meeting, the committee identified qualified director candidates with commensurate experience and background as replacement board members. In evaluating the board retirements and current needs of the board and the company, the nominating and governance committee focused on identifying board candidates that would add gender diversity to the board as well as background and core competencies in the fields of technology, cybersecurity, and public company governance. Potential director nominees were brought to the attention of the nominating and governance committee by board members, management, organizations, and database searches.

The nominating and governance committee continues to identify individuals as potential board of director candidates, particularly individuals with industry experience to support the company’s strategy to grow its two business platforms of regulated energy delivery and construction materials and services.

By tenure, if the nominees are elected, the board will be comprised of three directors who have served from 0-4 years, two directors who have served from 5-10 years, and five directors who have served over 11 years. This mix provides a balance of experience and institutional knowledge with fresh perspectives.

CORPORATE GOVERNANCE AND THE BOARD OF DIRECTORS

Director Independence

The board of directors has adopted guidelines on director independence that are included in our corporate governance guidelines. Our guidelines require that a substantial majority of the board consists of independent directors. In general, the guidelines require that an independent director must have no material relationship with the company directly or indirectly, except as a director. The board determines independence on the basis of the standards specified by the NYSE, the additional standards referenced in our corporate governance guidelines, and other facts and circumstances the board considers relevant. Based on its review, the board has determined that all directors, except for our chief executive officer Mr. Goodin, have no material relationship with us and are independent.

In determining director independence, the board of directors reviewed and considered information about any transactions, relationships, and arrangements between the non-employee directors and their immediate family members and affiliated entities on the one hand, and the company and its affiliates on the other, and in particular the following transactions, relationships, and arrangements:

• Charitable contributions by the MDU Resources Foundation (Foundation) to nonprofit organizations where a director or their spouse serves or served as a director, chair, or vice chair of the board of trustees, trustee, or member of the organization or related entity: The Foundation made charitable contributions to three such nonprofit organizations that collectively amounted to $8,650 in 2019. None of the contributions made to any of the nonprofit entities exceeded 2% of the relevant entity’s consolidated gross revenues.

• Business relationships with entities with which a director or director nominee is affiliated: Mr. Wilson is a member of the board of directors of HDR, Inc., an architectural, engineering, environmental, and consulting firm. The company paid HDR, Inc. or its affiliates approximately $900,000 in 2019 directly or through a third party for services which were provided in the ordinary course of business and on substantially the same terms prevailing for comparable services from other consulting firms. Mr. Wilson had no role in securing or promoting HDR, Inc. services and the relationship did not affect his independence under our corporate governance guidelines or the NYSE listing standards.

The board has also determined that all members of the audit, compensation, and nominating and governance committees of the board are independent in accordance with our guidelines and applicable NYSE and Securities Exchange Act of 1934 rules.

Sustainability and Social Responsibility

We view corporate responsibility as critical to our sustainability. While we are always focused on delivering strong financial performance, we are committed to doing so in a responsible manner that recognizes and respects the interests of all our stakeholders.

In recognition of its social responsibility and sustainability commitments, the board of directors in May 2019 formed the environmental and sustainability committee as a standing committee of the board with particular focus on our environmental, workplace health, safety, human capital, and other social sustainability programs and performance. Our environmental and sustainability committee is discussed further on page 22.

Also in 2019, the company issued an updated and expanded sustainability report based upon standards outlined by the Sustainability Accounting Standards Board or other industry organizations for each of our segment industries to provide investors and other interested stakeholders with information regarding our sustainability efforts. The sustainability report can be found on our website at

http://www.mdu.com/sustainability.

In August 2019, the Business Roundtable issued a statement on corporate social responsibility stating that its members share a fundamental commitment to all their stakeholders: customers, employees, suppliers, communities, and stockholders. With the company’s origin and rich history in providing electric and natural gas utility service to rural communities in the Dakotas and Montana, our utility companies have long operated under the motto, “In the Community to Serve^®.” With the addition of our construction businesses to our legacy of regulated energy delivery businesses, we define our purpose as “Building a Strong America^®” in recognition of our mission to deliver value to our stakeholders. In 2007, the company adopted its Leading with Integrity Guide, which sets out our commitments to stakeholders:

MDU Resources Group, Inc. Proxy Statement 17

• Commitment to Shareholders. We will always act in the best interests of the corporation and protect its assets.

• Commitment to Employees. We will work together to provide a safe and positive workplace.

• Commitment to Customers, Suppliers, and Competitors. We will compete in business only by lawful and ethical means.

• Commitment to Communities. We will be a responsible and valued corporate citizen.

Further detail on our commitments to our stakeholders can be found at http://www.mdu.com/commitmenttointegrity.

Stockholder Engagement

The company has an active stockholder outreach program. We believe in providing transparent and timely information to our investors. Each year we routinely engage directly or indirectly with our stockholders, including our top institutional stockholders. Management regularly attends and presents at investor and financial conferences and holds one-on-one meetings with investors and also interacts directly with investors and analysts during our quarterly earnings conference calls. During 2019, the company held meetings, conference calls, and webcasts with a diverse mix of stockholders including meetings or telephone conferences with eleven of the institutional investors included in our year-end top 30 stockholders. In our meetings or conferences, we discussed a variety of topics, including company strategy and our capital expenditure forecast; operational and financial updates; environmental, social, and corporate governance issues; sustainability; and, previously announced strategic initiatives. Feedback from engagements is shared by management with the board and its committees, and the discussions with some of our investors included the chair of our board of directors giving those stockholders the opportunity to provide feedback directly to a member of our board. The company also held telephone conferences with a proxy advisory firm to discuss corporate governance, executive compensation practices, and other topics.

Board Leadership Structure

The board separated the positions of chair of the board and chief executive officer in 2006, and our bylaws and corporate governance guidelines currently require that our chair be independent. The board believes this structure provides balance and is currently in the best interest of the company and its stockholders. Separating these positions allows the chief executive officer to focus on the full-time job of running our business, while allowing the chair to lead the board in its fundamental role of providing advice to and independent oversight of management. The chair meets regularly between board meetings with the chief executive officer and consults with the chief executive officer regarding the board meeting agendas, the quality and flow of information provided to the board, and the effectiveness of the board meeting process. The board believes this split structure recognizes the time, effort, and energy the chief executive officer is required to devote to the position in the current business environment, as well as the commitment required to serve as the chair, particularly as the board’s oversight responsibilities continue to grow and demand more time and attention. The fundamental role of the board of directors is to provide oversight of the management of the company in good faith and in the best interests of the company and its stockholders. Having an independent chair is a means to ensure the chief executive officer is accountable for managing the company in close alignment with the interests of stockholders including with respect to risk management as discussed below. An independent chair is in a position to encourage frank and lively discussions including during regularly scheduled executive sessions consisting of only independent directors and to assure that the company has adequately assessed all appropriate business risks before adopting its final business plans and strategies. The board believes that having separate positions and having an independent outside director serve as chair is the appropriate leadership structure for the company at this time and demonstrates our commitment to good corporate governance. With the retirement of Mr. Pearce at the 2019 annual meeting, the board elected Mr. Johnson as its independent chair at its May 2019 board meeting.

Board’s Role in Risk Oversight

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including economic risks, strategic risks, operational risks, environmental and regulatory risks, the impact of competition, climate and weather conditions, limitations on our ability to pay dividends, pension plan obligations, cyberattacks or acts of terrorism, and third party liabilities. Management is responsible for identifying material risks, implementing appropriate risk management and mitigation strategies, and providing information regarding material risks and risk management and mitigation to the board. The board, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate for identifying, assessing, and managing risk.

18 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

The board believes establishing the right “tone at the top” and full and open communication between management and the board of directors are essential for effective risk management and oversight. Our chair meets regularly with our chief executive officer to discuss strategy and risks facing the company. Senior management attends the quarterly board meetings and is available to address any questions or concerns raised by the board on risk management-related and any other matters. Each quarter, the board of directors receives presentations from senior management on strategic matters involving our operations. Senior management annually presents an assessment to the board of critical enterprise risks that threaten the company’s strategy and business model including risks inherent in the key assumptions underlying the company’s business strategy for value creation. Periodically, the board receives presentations from external experts on matters of strategic importance to the board. At least annually, the board holds strategic planning sessions with senior management to discuss strategies, key challenges, and risks and opportunities for the company.

The company has also developed a robust compliance program to promote a culture of compliance, consistent with the right tone at the top, to mitigate risk. The program includes training and adherence to our code of conduct and legal compliance guide. We further mitigate risk through our internal audit and legal departments.

While the board is ultimately responsible for risk oversight at our company, our standing board committees assist the board in fulfilling its oversight responsibilities in certain areas of risk.

• The audit committee assists the board in fulfilling its oversight responsibilities with respect to risk management in a general manner and specifically in the areas of financial reporting, internal controls, cybersecurity, and compliance with legal and regulatory requirements, and, in accordance with NYSE requirements, discusses with the board policies with respect to risk assessment and risk management and their adequacy and effectiveness. The audit committee receives regular reports on the company’s compliance program, including reports received through our anonymous reporting hot line. It also receives reports and regularly meets with the company’s external and internal auditors. During its quarterly meetings in 2019, the audit committee received presentations or reports from management on cybersecurity and the company’s mitigation of cybersecurity risks. The entire board was present for the presentations and had access to the reports. Risk assessment and mitigation reports are regularly provided by management to the audit committee or the full board. This opens the opportunity for discussions about areas where the company may have material risk exposure, steps taken to manage such exposure, and the company’s risk tolerance in relation to company strategy. The audit committee reports regularly to the board of directors on the company’s management of risks in the audit committee’s areas of responsibility.

• The compensation committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs.

• The nominating and governance committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks associated with board organization, board membership and structure, succession planning for our directors and executive officers, and corporate governance.

• The environmental and sustainability committee was established in May 2019 and assists the board in fulfilling its oversight responsibilities with respect to the management of risks related to environmental matters, physical and other workplace hazards, employee and public safety, and other social sustainability matters.

Board Meetings and Committees

During 2019, the board of directors held four regular meetings and one special meeting. Each director attended at least 75% of the combined total meetings of the board and the committees on which the director served during 2019 (held during the period he or she was a director). Directors are encouraged to attend our annual meeting of stockholders. All but one director attended our 2019 Annual Meeting of Stockholders.

The board has standing audit, compensation, nominating and governance, and environmental and sustainability committees which meet at least quarterly. Following the 2019 annual meeting and the establishment of the environmental and sustainability committee, new chairs were elected to the standing committees, and membership changes were made to each committee. The table below provides current committee membership.

Below is a description of each standing committee of the board. The board has affirmatively determined that each of these standing committees consists entirely of independent directors pursuant to rules established by the NYSE, rules promulgated under the Securities and Exchange Commission (SEC), and the director independence standards established by the board. The board has also determined that each member of the audit committee and the compensation committee is independent under the criteria established by the NYSE and the SEC for audit committee and compensation committee members, as applicable.

Nominating and Governance Committee Met Four Times in 2019

The nominating and governance committee met four times during 2019. The current committee members are Edward A. Ryan, chair, Thomas Everist, David M. Sparby, and John K. Wilson.

The nominating and governance committee is governed by a written charter and provides recommendations to the board with respect to:

• board organization, membership, and function;

• committee structure and membership;

• succession planning for our executive management and directors; and

• our corporate governance guidelines.

The nominating and governance committee assists the board in overseeing the management of risks in the committee’s areas of responsibility.

The committee identifies individuals qualified to become directors and recommends to the board the director nominees for the next annual meeting of stockholders. The committee also identifies and recommends to the board individuals qualified to become our principal officers and the nominees for membership on each board committee. The committee oversees the evaluation of the board and management.

In identifying nominees for director, the committee consults with board members, management, consultants, organizational representatives, and other individuals likely to possess an understanding of our business and knowledge concerning suitable director candidates.

In evaluating director candidates, the committee, in accordance with our corporate governance guidelines, considers an individual’s:

• background, character, and experience, including experience relative to our company’s lines of business;

• skills and experience which complement the skills and experience of current board members;

• success in the individual’s chosen field of endeavor;

• skill in the areas of accounting and financial management, banking, business management, human resources, marketing, operations, public affairs, law, technology, risk management, governance, and operations abroad;

• background in publicly traded companies including service on other public company boards of directors;

20 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

• geographic area of residence;

• diversity of business and professional experience, skills, gender, and ethnic background, as appropriate in light of the current composition and needs of the board;

• independence, including any affiliation or relationship with other groups, organizations, or entities; and

• compliance with applicable law and applicable corporate governance, code of conduct and ethics, conflict of interest, corporate opportunities, confidentiality, stock ownership and trading policies, and other policies and guidelines of the company.

In addition, our bylaws contain requirements that a person must meet to qualify for service as a director.

The nominating and governance committee assesses these considerations annually in connection with the nomination of directors for election at the annual meeting of stockholders. The committee seeks a collective background of board members to provide a portfolio of experience and knowledge that serves the company’s governance and strategic needs and best perpetrates our long-term success. Directors should have demonstrated experience and knowledge that is relevant to the board’s oversight role of the company’s business. The nominating and governance committee also considers the board’s diversity in recommending nominees, including diversity of experience, expertise, ethnicity, gender, and geography. The composition of the current board and the board nominees reflects diversity in business and professional experience, skills, ethnicity, gender, and geography.

Audit Committee Met Eight Times in 2019

The audit committee is a separately-designated committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 and is governed by a written charter.

The audit committee met eight times during 2019. The current audit committee members are David M. Sparby, chair, Mark A. Hellerstein, Edward A. Ryan, and Chenxi Wang. The board of directors has determined that Messrs. Sparby and Hellerstein are “audit committee financial experts” as defined by SEC rules, and all audit committee members are financially literate within the meaning of the listing standards of the NYSE. All members also meet the independence standard for audit committee members under our director independence guidelines, the NYSE listing standards, and SEC rules.

The audit committee assists the board of directors in fulfilling its oversight responsibilities to the stockholders and serves as a communication link among the board, management, the independent registered public accounting firm, and the internal auditors. The committee reviews and discusses with management and the independent auditors, before filing with the SEC, the annual audited financial statements and quarterly financial statements. The audit committee also:

• assists the board’s oversight of

◦ the integrity of our financial statements and system of internal controls;

◦ the company’s compliance with legal and regulatory requirements and the code of conduct;

◦ discussions with management regarding the company’s earnings releases and guidance;

◦ the independent registered public accounting firm’s qualifications and independence;

◦ the appointment, compensation, retention, and oversight of the work of the independent registered public accounting firm;

◦ the performance of our internal audit function and independent registered public accounting firm;

◦ management of risk in the audit committee’s areas of responsibility, including cybersecurity, financial reporting, legal and regulatory compliance, and internal controls; and

• arranges for the preparation of and approves the report that SEC rules require we include in our annual proxy statement. See the section entitled “Audit Committee Report” for further information.

Compensation Committee Met Four Times in 2019

During 2019, the compensation committee met four times. The compensation committee consists entirely of independent directors within the meaning of the company’s corporate governance guidelines and the NYSE listing standards and who meet the definitions of non-employee directors for purposes of Rule 16-b under the Exchange Act. Current members of the compensation committee are John K. Wilson, chair, Thomas Everist, Karen B. Fagg, and Patricia L. Moss.

The compensation committee is governed by a written charter and assists the board of directors in fulfilling its responsibilities relating to the company’s compensation policies and programs. It has direct responsibility for determining compensation for our Section 16 officers and for overseeing the company’s management of compensation risk in its areas of responsibility. The compensation committee also reviews and recommends any changes to director compensation policies to the board of directors. The authority and responsibility of the compensation committee is outlined in the compensation committee’s charter.

The compensation committee uses analysis and recommendations from outside consultants, the chief executive officer, and the human resources department in making its compensation decisions. The chief executive officer, the vice president-human resources, and the general counsel regularly attend compensation committee meetings. The committee meets in executive session as needed. The processes and procedures for consideration and determination of compensation of the Section 16 officers as well as the role of our executive officers are discussed in the “Compensation Discussion and Analysis.”

The compensation committee has sole authority to retain compensation consultants, legal counsel, or other advisers to assist in consideration of the compensation of the chief executive officer, the other Section 16 officers, and the board of directors. The committee is directly responsible for the appointment, compensation, and oversight of the work of such advisers. The compensation committee’s practice has been to retain a compensation consultant every other year to conduct a competitive analysis on executive compensation. The competitive analysis is conducted internally by the human resources department in the other years. In 2018, the compensation committee retained a compensation consultant, Meridian Compensation Partners, LLC (“Meridian”), to conduct a competitive analysis on executive compensation for 2019. In 2019, the human resources department conducted the executive officer market analysis of the Section 16 officers with a review of the analysis by the compensation consultant, Meridian. Prior to retaining an adviser, the compensation committee considers all factors relevant to ensure the adviser’s independence from management. Annually the compensation committee conducts a potential conflicts of interest assessment raised by the work of any compensation consultant and how such conflicts, if any, should be addressed. The compensation committee requested and received information from Meridian to assist in its potential conflicts of interest assessment. Based on its review and analysis, the compensation committee determined in 2019 that Meridian was independent from management.

The board of directors determines compensation for our non-employee directors based upon recommendations from the compensation committee. The compensation committee’s practice has been to retain a compensation consultant every other year to conduct a competitive analysis on director compensation. In 2019, the analysis of non-employee director compensation was performed by the compensation consultant, Meridian.

Environmental and Sustainability Committee Met Two Times in 2019

The environmental and sustainability committee was formed by the board of directors in May 2019 and met twice during the balance of 2019. The committee is governed by a written charter and consists entirely of independent directors within the meaning of the company’s corporate governance guidelines and the listing standards of the NYSE. The current members of the committee are Karen B. Fagg, chair, Mark A. Hellerstein, Patricia L. Moss, and Chenxi Wang.

The environmental and sustainability committee oversees and provides recommendations to the board with respect to the company’s policies, strategies, public policy positions, programs, and performance related to environmental, workplace health, safety, and other social sustainability matters. The environmental and sustainability committee:

• reviews significant risks regarding environmental and social sustainability matters that fundamentally affect the company’s business interests and long-term viability;

• reviews the company’s environmental and social sustainability strategies, policies, processes, programs, and performance;

• reviews recent and emerging environmental and social sustainability matters;

22 MDU Resources Group, Inc. Proxy Statement

• reviews labor and human relations issues related to the company’s operations;

• reviews any fatality, serious injury, or illness involving an employee, customer, contractor, or third-party occurring in connection with the company’s operations;

• reviews any material noncompliance by the company with environmental, health, and safety laws and regulations;

• reviews the company’s efforts to advance progress on sustainable development;

• reviews methods to communicate the company’s environmental and social sustainability values and performance;

• considers and advises the compensation committee on the company’s performance with respect to incentive compensation metrics relating to environmental and social sustainability matters;

• reports to, advises, and makes recommendations to the board on environmental and social sustainability matters affecting the company;

• reviews the company’s environmental and social sustainability disclosures;

• reviews stockholder proposals related to environmental and social sustainability matters; and

• reviews significant legislative, regulatory, political, and social issues and trends that may affect the company’s environmental, sustainability, health, and safety management processes and systems.

Stockholder Communications with the Board

Stockholders and other interested parties who wish to contact the board of directors or any individual director, including our non-employee chair or non-employee directors as a group, should address a communication in care of the secretary at MDU Resources Group, Inc., P.O. Box 5650, Bismarck, ND 58506-5650. The secretary will forward all communications.

Additional Governance Features

Board and Committee Evaluations

Our corporate governance guidelines provide that the board of directors, in coordination with the nominating and governance committee, will annually review and evaluate the performance and functioning of the board and its committees. The self-evaluations are intended to facilitate a candid assessment and discussion by the board and each committee of its effectiveness as a group in fulfilling its responsibilities, its performance as measured against the corporate governance guidelines, and areas for improvement. The board and committee members are provided with a questionnaire to facilitate discussion. The results of the evaluations are reviewed and discussed in executive sessions of the committees and the board of directors.

Executive Sessions of the Independent Directors

The non-employee directors meet in executive session at each regularly scheduled quarterly board of directors meeting. The chair of the board presides at the executive session of the non-employee directors.

Director Resignation Upon Change of Job Responsibility

Our corporate governance guidelines require a director to tender his or her resignation after a material change in job responsibility. In 2019, no directors or director nominees submitted resignations under this requirement.

Majority Voting in Uncontested Director Elections

Our corporate governance guidelines require that in uncontested elections (those where the number of nominees does not exceed the number of directors to be elected), director nominees must receive the affirmative vote of a majority of the votes cast to be elected to our board of directors. Contested director elections (those where the number of director nominees exceeds the number of directors to be elected) are governed by a plurality of the vote of shares present in person or represented by proxy at the meeting.

The board has adopted a director resignation policy for incumbent directors in uncontested elections. Any proposed nominee for re-election as a director shall, before he or she is nominated to serve on the board, tender to the board his or her irrevocable resignation that will be effective, in an uncontested election of directors only, upon (i) such nominee’s receipt of a greater number of votes “against” election than votes “for” election at our annual meeting of stockholders; and (ii) acceptance of such resignation by the board of directors.

MDU Resources Group, Inc. Proxy Statement 23

Director Overboarding Policy

Our bylaws and corporate governance guidelines state that a director may not serve on more than two other public company boards. Currently, all of our directors are in compliance of this policy.

Board Refreshment

The company regularly evaluates the need for board refreshment. The nominating and governance committee and the board focus on identifying individuals whose skills and experiences will enable them to make meaningful contributions to shaping the company’s business strategy. As part of its consideration of director succession, the nominating and governance committee from time to time reviews, including when considering potential candidates, the appropriate skills and characteristics required of board members. The board believes it is important to consider diversity of skills, expertise, race, ethnicity, gender, age, education, geography, cultural background, and professional experiences in evaluating board candidates for expected contributions to an effective board. Independent directors may not serve on the board beyond the next annual meeting of stockholders after attaining the age of 76. We believe the mandatory retirement age allows us to benefit from experienced directors, with industry expertise, company institutional knowledge and historical perspective, stability, and comfort with challenging company management, while maintaining our ability to refresh the board through the addition of new members. In connection with our mandatory retirement for directors, Harry J. Pearce and William E. McCracken retired as directors at the completion of their term following the 2019 annual meeting. Two replacement members were added to the board of directors. Edward A. Ryan was appointed to the board of directors in November 2018, and subsequently elected to the board in May 2019, and Chenxi Wang was elected to the board of directors in May 2019.

Our corporate governance guidelines include our policy on consideration of director candidates recommended to us. We will consider candidates that our stockholders recommend in the same manner we consider other nominees. Stockholders who wish to recommend a director candidate may submit recommendations, along with the information set forth in the guidelines, to the nominating and governance committee chair in care of the secretary at MDU Resources Group, Inc., P.O. Box 5650, Bismarck, ND 58506-5650.

Stockholders who wish to nominate persons for election to our board at an annual meeting of stockholders must follow the applicable procedures set forth in Section 2.08 or 2.10 of our bylaws. Our bylaws are available on our website. See “Stockholder Proposals, Director Nominations, and Other Items of Business for 2021 Annual Meeting” in the section entitled “Information about the Annual Meeting” for further details.

Prohibitions on Hedging/Pledging Company Stock

The director compensation policy prohibits directors from hedging their ownership of common stock, pledging company stock as collateral for a loan, or holding company stock in an account that is subject to a margin call.

Code of Conduct

We have a code of conduct and ethics, which we refer to as the Leading With Integrity Guide. It applies to all directors, officers, and employees.

We intend to satisfy our disclosure obligations regarding amendments to, or waivers of, any provision of the code of conduct that applies to our principal executive officer, principal financial officer, and principal accounting officer, and that relates to any element of the code of ethics definition in Regulation S-K, Item 406(b), and waivers of the code of conduct for our directors or executive officers, as required by NYSE listing standards, by posting such information on our website.

Proxy Access

Our bylaws allow stockholders to nominate directors for inclusion in our proxy statement subject to the following parameters:

Ownership Threshold:	3% of outstanding shares of our common stock
Nominating Group Size:	Up to 20 stockholders may combine to reach the 3% ownership threshold
Holding Period:	Continuously for three years
Number of Nominees:	The greater of two nominees or 20% of our board

We believe these proxy access parameters reflect a well designed and balanced approach to proxy access that mitigates the risk of abuse and protects the interests of all of our stockholders. Stockholders who wish to nominate directors for inclusion in our Proxy Statement in accordance with proxy access must follow the procedures in Section 2.10 of our bylaws. See “Stockholder Proposals, Director Nominations, and Other Items of Business for 2021 Annual Meeting.”

Related Person Transaction Disclosure

The board of directors’ policy for the review of related person transactions is contained in our corporate governance guidelines. The policy requires the audit committee to review any transaction, arrangement or relationship, or series thereof:

• in which the company was or will be a participant;

• the amount involved exceeds $120,000; and

• a related person had or will have a direct or indirect material interest.

The purpose of this review is to determine whether this transaction is in the best interests of the company.

Related persons are directors, director nominees, executive officers, holders of 5% or more of our voting stock, and their immediate family members. Related persons are required promptly to report to our general counsel all proposed or existing related person transactions in which they are involved.

If our general counsel determines that the transaction is required to be disclosed under the SEC rules, the general counsel furnishes the information to the chair of the audit committee. After its review, the committee makes a determination or a recommendation to the board and officers of the company with respect to the related person transaction. Upon receipt of the committee’s recommendation, the board of directors or officers, as the case may be, take such action as they deem appropriate in light of their responsibilities under applicable laws and regulations.

We had no related person transactions in 2019.

Director Compensation for 2019

MDU Resources’ non-employee directors are compensated for their service according to the MDU Resources Group Inc. Director Compensation Policy. Only one company employee, David L.

¹  Directors receive an annual payment of $125,000 in company common stock, except the non-executive chair who receives $150,000 in company common stock, under the MDU Resources Group, Inc. Non-Employee Director Long-Term Incentive Compensation Plan. Directors serving less than a full year receive a prorated stock payment based on the number of months served. All stock payments are measured in accordance with Financial Accounting Standards Board (FASB) generally accepted accounting principles for stock-based compensation in FASB Accounting Standards Codification Topic 718. The grant date fair value is based on the purchase price of our common stock on the grant date of November 19, 2019, which was $29.16 per share. The amount paid in cash for fractional shares is included in the amount reported in the stock awards column to this table. As of December 31, 2019, there are no outstanding stock awards or options associated with the Non-Employee Director Long-Term Incentive Compensation Plan. 

² Includes group life insurance premiums and charitable donations made on behalf of the director as applicable. Amounts for life insurance premiums reflect prorated amounts for directors serving less than a full year based on the number of months served.

³  Messrs. McCracken and Pearce retired from the board on May 7, 2019.

⁴  Mr. Sparby elected to receive shares of our common stock in lieu of his $90,417 of fees earned in cash. He received a total of 3,295 shares of company common stock which was purchased during 2019 on March 29, June 28, September 30, and December 31 at market prices of $25.66, $25.47, $28.39, and $29.54, respectively.

Other Compensation

In addition to liability insurance, we maintain group life insurance in the amount of $100,000 on each non-employee director for the benefit of their beneficiaries during the time they serve on the board. The annual cost per director is $82.80. Directors who contribute to the company’s Good Government Fund may designate up to two charities to receive a matching donation from the MDU Resources Foundation based on their contributions to the fund. Directors are reimbursed for all reasonable travel expenses, including spousal expenses in connection with attendance at meetings of the board and its committees. Perquisites, if any, were below the disclosure threshold in 2019.

Deferral of Compensation

Directors may defer all or any portion of the annual cash retainer and any other cash compensation paid for service as a director pursuant to the Deferred Compensation Plan for Directors. Deferred amounts are held as phantom stock with dividend accruals and are paid out in cash over a five-year period after the director leaves the board.

Post-Retirement

Our post-retirement income plan for directors was terminated in May 2001 for current and future directors. The net present value of each director’s benefit was calculated and converted into phantom stock. Payment is deferred pursuant to the Deferred Compensation Plan for Directors and will be made in cash over a five-year period after the director’s retirement from the board.

Stock Ownership Policy

Our director stock ownership policy contained in our corporate governance guidelines requires each director to beneficially own our common stock equal in value to five times the director’s annual cash base retainer. Shares acquired through purchases on the open market and received through our Non-Employee Director Long-Term Incentive Compensation Plan are considered in ownership calculations as well as other beneficial ownership of our common stock by a spouse or other immediate family member residing in the director’s household. A director is allowed five years commencing January 1 of the year following the year of the director’s initial election to the board to meet the requirements. The level of common stock ownership is monitored with an annual report made to the compensation committee of the board. All directors are in compliance with the stock ownership policy or are within the first five years of their election to the board.

Hedging Policy

The company’s Director Compensation Policy and its Executive Compensation Policy prohibit our directors and executives from hedging their ownership of company stock. The Director Compensation Policy applies to all directors who are not full-time employees of the company. The Executive Compensation Policy applies to the executives of the company designated as an officer for purposes of Section 16 of the Securities Exchange Act of 1934 as well as all other executives of the company and its subsidiaries who participate in its Long-Term Performance-Based Incentive Plan and its Executive Incentive Compensation Plan. Under the policies, directors and executives are prohibited from engaging in transactions that allow them to own stock technically but without the full benefits and risks of such ownership, including, but not limited to, zero-cost collars, equity swaps, straddles, prepaid variable forward contracts, security futures contracts, exchange funds, forward sale contracts, and other financial transactions that allow the director or executive to benefit from the devaluation of the company’s stock.

The company policies also prohibit directors, executives, and related persons from holding company stock in a margin account, with certain exceptions, or pledging company securities as collateral for a loan. Company common stock may be held in a margin brokerage account only

EXECUTIVE COMPENSATION

ITEM 2. ADVISORY VOTE TO APPROVE THE COMPENSATION PAID TO THE COMPANY’S NAMED EXECUTIVE OFFICERS

In accordance with Section 14A of the Securities Exchange Act of 1934 and Rule 14a-21(a), we are asking our stockholders to approve, in an advisory vote, the compensation of our named executive officers as disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K. As discussed in the Compensation Discussion and Analysis, the compensation committee and board of directors believe the current executive compensation program directly links compensation of the named executive officers to our financial performance and aligns the interests of the named executive officers with those of our stockholders. The compensation committee and board of directors also believe the executive compensation program provides the named executive officers with a balanced compensation package that includes an appropriate base salary along with competitive annual and long-term incentive compensation targets. These incentive programs are designed to reward the named executive officers on both an annual and long-term basis if they attain specified goals.

Our overall compensation program and philosophy for 2019 was built on a foundation of these guiding principles:

• we pay for performance, with over 65% of our 2019 total target direct compensation for the named executive officers in the form of performance-based incentive compensation;

• we review competitive compensation data for the named executive officers, to the extent available, and incorporate internal equity in the final determination of target compensation levels;

• we align executive compensation and performance by using annual performance incentives based on criteria that are important to stockholder value, including earnings, earnings per share, and earnings before interest, taxes, depreciation, and amortization (EBITDA); and

• we align executive compensation and performance by using long-term performance incentives based on total stockholder return relative to our peer group and financial measures important to company growth.

We are asking our stockholders to indicate their approval of our named executive officer compensation as disclosed in this Proxy Statement, including the Compensation Discussion and Analysis, the executive compensation tables, and narrative discussion. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers for 2019. Accordingly, the following resolution is submitted for stockholder vote at the 2020 annual meeting:

“RESOLVED, that the compensation paid to the company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables, and narrative discussion of this Proxy Statement, is hereby approved.”

As this is an advisory vote, the results will not be binding on the company, the board of directors, or the compensation committee and will not require us to take any action. The final decision on the compensation of the named executive officers remains with the compensation committee and the board of directors, although the board and compensation committee will consider the outcome of this vote when making future compensation decisions. We intend to hold this advisory vote every year until at least the next stockholder advisory vote on the frequency of this vote.

The board of directors recommends a vote “for” the approval, on a non-binding

advisory basis, of the compensation of the company’s named executive officers,

as disclosed in this Proxy Statement.

Approval of the compensation of the named executive officers requires the affirmative vote of a majority of the common stock present in person or represented by proxy at the meeting and entitled to vote on the proposal. Abstentions will count as votes against this proposal. Broker non-vote shares are not entitled to vote on this proposal and, therefore, are not counted in the vote.

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation Discussion and Analysis describes how our named executive officers were compensated for 2019 and how their 2019 compensation aligns with our pay-for-performance philosophy. It also describes the oversight of the compensation committee and the rationale and processes used to determine the 2019 compensation of our named executive officers including the objectives and specific elements of our compensation program.

The Compensation Discussion and Analysis may contain statements regarding corporate performance targets and goals. The targets and goals are disclosed in the limited context of our compensation programs and should not be understood to be statements of management’s expectations or estimates of results or other guidance. We specifically caution investors not to apply these statements to other contexts.

Jason L. Vollmer	Vice President, Chief Financial Officer (CFO) and Treasurer

Nicole A. Kivisto	President and Chief Executive Officer - Electric and Natural Gas Distribution Segments

Executive Summary

Pay for Performance

The compensation committee is responsible for designing and approving our executive compensation program and setting compensation opportunities for named executive officers. Our compensation program is directly linked to our business strategy to ensure officers are focused on elements that drive our business strategy and create stockholder value. To ensure management’s interests are aligned with those of our stockholders and the performance of the company, the significant majority of the CEO’s and the other named executive officers’ target compensation is dependent on the achievement of company performance targets. The charts below show the target pay mix for the CEO and average target pay mix of the other named executive officers, including base salary and the annual and long-term incentives.

Annual Base Salary

We provide our executive officers with base salary at a sufficient level to attract, recruit, and retain executives with the knowledge, skills, and abilities necessary to successfully execute their job responsibilities. Consistent with our compensation philosophy of linking pay to performance, our executives receive a relatively smaller percentage of their overall target compensation in the form of base salary. In establishing base salaries, the compensation committee considers each executive’s individual performance, the scope and complexities of their responsibilities, internal equity, and whether the base salary is competitive as measured against the base salaries of similarly situated executives in our peer group and market compensation data.

MDU Resources Group, Inc. Proxy Statement 33

Proxy Statement

Annual Cash Incentive Awards

Annual cash incentive awards for our executive officers are linked to performance by rewarding achievement of financial goals and ensuring our executive officers are focused and accountable for our growth and profitability. The design of the annual cash incentive award opportunities for 2019 was the same as the design used in 2018. Each executive is assigned a target annual incentive award based on a percentage of the executive’s base salary. The actual annual cash incentive realized is determined by multiplying the target award by the payout percentage associated with the achievement of the executive’s performance measures.

The compensation committee selected specific business segment financial performance measures for the business segment executives which represented 80% of their annual incentive award opportunity. The other 20% of the business segment executives’ annual incentive award opportunity was based on the achievement of overall company earnings per share (EPS). These measures incentivize our business segment executives to focus on the success and performance of their business segment while keeping the overall success of the company in mind.

The annual cash incentive award for corporate executives (including our CEO and CFO) is based on the achievement of the performance measures for each business segment executive and weighted by each business segment’s invested capital relative to the company’s total invested capital. Each corporate executive’s target award is multiplied by the sum of the weighted achievement percentage for each business segment executive to derive the corporate executive’s realized annual award. This incentivizes the corporate executives to assist the business segments in their success while still emphasizing overall company performance. See the “Annual Incentives” section within this Compensation Discussion and Analysis for further details on our company’s annual cash incentive program.

The following chart shows the percentage payout of the annual incentive target realized by our CEO compared to earnings per share from continuing operations for the last five years. The chart demonstrates the alignment between our financial performance and realized annual cash incentive compensation.

*MDU Resources Group, Inc. reported 2017 earnings from continuing operations of $1.45 per share which included a non-recurring benefit of 20 cents per share attributable to the federal Tax Cuts and Jobs Act that was signed into law on December 22, 2017.

34 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

Long-Term Equity-Based Incentive Awards

Our compensation committee and the board approve grants of long-term incentives to our executives in the form of performance shares which vest into company stock plus dividend equivalents at the end of a three-year performance cycle upon achievement of established performance measures. The following chart depicts the actual vesting percentage for the last five performance cycles and demonstrates the alignment between total stockholder return (TSR) and realized long-term incentive compensation by our executives.

See the “Long-Term Incentives” section within this Compensation Discussion and Analysis for further details on the company’s long-term incentive program.

With the majority of our executive officer’s compensation dependent on the achievement of robust performance measures set by the compensation committee, we believe there is substantial alignment between executive pay and the company’s performance.

Stockholder Advisory Vote (“Say on Pay”)

At our 2019 Annual Meeting of Stockholders, 96.8% of the votes cast on the “Say on Pay” proposal approved the compensation of our named executive officers. The compensation committee viewed the 2019 vote as an expression of the stockholders general satisfaction with the company’s executive compensation programs. The compensation committee reviewed and considered the 2019 vote on “Say on Pay” in setting compensation for 2020 by continuing to link performance-based annual and long-term incentives to company financial performance and stockholder value.

Compensation Practices

Our practices and policies ensure alignment between the interests of our stockholders and our executives as well as effective compensation governance.

What We Do
þ	Pay for Performance - Annual and long-term award incentives tied to performance measures set by the compensation committee comprise the largest portion of executive compensation.
þ	Independent Compensation Committee - All members of the compensation committee meet the independence standards under the New York Stock Exchange listing standards and the Securities and Exchange Commission rules.
þ	Independent Compensation Consultant - The compensation committee retains an independent compensation consultant to evaluate executive compensation plans and practices.
þ	Competitive Compensation - Executive compensation reflects executive performance, experience, relative value compared to other positions within the company, relationship to competitive market value compensation, business segment economic environment, and the actual performance of the overall company and the business segments.
þ	Annual Cash Incentive - Payment of annual cash incentive awards are based on business segment and overall company performance against pre-established annual financial measures.
þ	Long-Term Equity Incentive - Long-term incentive awards may be earned at the end of a three-year period based on achieving pre-established performance measures and are paid through performance shares which encourages stock ownership and helps retain management talent.
þ	Balanced Mix of Pay Components - The target compensation mix is not overly weighted toward annual incentive awards but rather represents a balance of annual cash and long-term equity-based compensation.
þ	Mix of Financial Goals - Use of a mixture of financial goals to measure performance prevents overemphasis on a single metric.
þ	Annual Compensation Risk Analysis - Risks related to our compensation programs are regularly analyzed through an annual compensation risk assessment.
þ	Stock Ownership and Retention Requirements - Executive officers are required to own, within five years of appointment or promotion, company common stock equal to a multiple of their base salary. Our president and chief executive officer is required to own stock equal to four times his base salary, and the other named executive officers are required to own stock equal to three times their base salary. The executive officers also must retain at least 50% of the net after-tax shares of stock vested through the long-term incentive plan for the earlier of two years or until termination of employment. Net performance shares must also be held until share ownership requirements have been met.
þ	Clawback Policy - If the company’s audited financial statements are restated due to any material noncompliance with the financial reporting requirements under the securities laws, the compensation committee may, or shall if required, demand repayment of some or all incentives paid to our executive officers within the last three years.
What We Do Not Do
ý	Stock Options - The company does not use stock options as a form of incentive compensation.
ý	Employment Agreements - Executives do not have employment agreements entitling them to specific payments upon termination or a change of control of the company.
ý	Perquisites - Executives do not receive perquisites that materially differ from those available to employees in general.
ý	Hedge Stock - Executives are not allowed to hedge company securities.
ý	Pledge Stock-Executives are not allowed to pledge company securities in margin accounts or as collateral for loans.
ý	No Dividends or Dividend Equivalents on Unvested Shares - We do not provide for payment of dividends or dividend equivalents on unvested share awards.
ý	Tax Gross-Ups - Executives do not receive tax gross-ups on their compensation except for circumstances regarding relocation.

2019 Compensation Framework

Objectives of our Compensation Program

We have a written executive compensation policy for our executive officers, including all the named executive officers. Our policy’s stated objectives are to:

• recruit, motivate, reward, and retain high performing executive talent required to create superior shareholder value;

• reward executives for short-term performance as well as for growth in enterprise value over the long-term;

• ensure effective utilization and development of talent by working in concert with other management processes - for example, performance appraisal, succession planning, and management development;

• help ensure that compensation programs do not encourage or reward excessive or imprudent risk taking; and

• provide a competitive package relative to industry-specific and general industry comparisons and internal equity, as appropriate.

Compensation Decision Process for 2019

For 2019, the compensation committee made recommendations to the board of directors regarding compensation of all executive officers, and the board of directors then approved the recommendations. The CEO’s role in the process includes the assessment of executive officer performance and recommending base salaries for the executive officers other than himself. The CEO attended all compensation committee meetings but was not present during discussions of his compensation. At its meetings in November 2018 and February 2019, the compensation committee established and approved base salaries and performance measures for the annual and long-term incentive compensation for 2019. It also certified the achievement of performance measures for 2018 associated with annual and long-term incentive compensation that was paid or vested in 2019.

At least every two years, the compensation committee hires an independent consulting firm to assess and recommend competitive pay levels, including base salaries and incentive compensation, associated with executive officer positions. Typically the consulting firm conducts its analysis in even numbered years. In odd numbered years, the assessment has been performed by the company’s human resources department using a variety of industry specific sources. In August 2018, the compensation committee’s consultant, Meridian Compensation Partners LLC, prepared the analysis of and provided recommendations for the 2019 executive compensation structure.

Compensation Policies and Practices as They Relate to Risk Management

The human resources department conducts an annual risk assessment of our compensation programs. Senior management and our management policy committee reviewed the risk assessment for 2019 and concluded our compensation policies and practices do not create risks which could have a material adverse effect on the company. After review and discussion of the assessment with senior management, the compensation committee concurred with management’s assessment.

In assessing the risks arising from our compensation policies and practices, the human resources department identified the following practices designed to prevent excessive risk taking:

• Business management and governance practices:

◦ risk management is a specific performance competency included in the annual performance assessment of Section 16 officers;

◦ board oversight on capital expenditure and operating plans promotes careful consideration of financial assumptions;

◦ limitation on business acquisitions without board approval;

◦ employee integrity training programs and anonymous reporting systems;

◦ quarterly risk assessment reports at audit committee meetings; and

◦ prohibitions on holding company stock in an account that is subject to a margin call, pledging company stock as collateral for a loan, and hedging of company stock by Section 16 officers and directors.

• Executive compensation practices:

◦ active compensation committee review of executive compensation, including portions of executive compensation based upon the company’s total stockholder return in relation to that of the company’s peer group;

◦ the initial determination of a position’s salary grade to be at or near the 50th percentile of base salaries paid to similar positions at peer group companies and/or relevant industry companies;

◦ consideration of peer group and/or relevant industry practices to establish appropriate compensation target amounts;

◦ a balanced compensation mix of fixed salary and annual and long-term incentives tied primarily to the company’s financial and stock performance;

MDU Resources Group, Inc. Proxy Statement 37

Proxy Statement

◦ use of interpolation for annual and long-term incentive awards to avoid payout cliffs;

◦ negative discretion to adjust any annual incentive award payment downward;

◦ use of caps on annual incentive awards (maximum of 200% of target for regulated segments and 240% of target for construction materials and services segments) and long-term incentive stock grant awards (maximum of 200% of target);

◦ ability to clawback incentive payments in the event of a financial restatement;

◦ use of performance shares and restricted stock units, rather than stock options or stock appreciation rights, as an equity component of incentive compensation;

◦ use of performance shares for long-term incentive awards with relative total stockholder return, earnings before interest, taxes, depreciation, and amortization (EBITDA) growth, and earnings growth performance measures;

◦ use of three-year performance periods for performance shares and restricted stock units to discourage short-term risk-taking;

◦ substantive annual incentive goals measured primarily by earnings, EBITDA, earnings per share criteria, and compound earnings and EBITDA growth, which encourage balanced performance and are important to stockholders;

◦ use of financial performance metrics that are readily monitored and reviewed;

◦ regular review of companies in the peer group to ensure appropriateness and industry match;

◦ stock ownership requirements for the board and for executives participating in the MDU Resources Long-Term Performance-Based Incentive Plan;

◦ Mandatory holding periods of all company stock awards to executives until stock ownership requirements are achieved and mandatory holding period for 50% of any net after-tax shares of stock earned under long-term incentive awards until the earlier of: (1) the end of the two-year period commencing on the date any stock earned under such award is issued, and (2) the executive’s termination of employment; and

◦ use of independent consultants to assist in establishing pay targets and compensation structure at least biennially.

Components of Compensation

Our executive compensation program is designed to promote sustained long-term profitability and create stockholder value. The components of our executive officer’s compensation are selected to drive financial and operational results as well as align the executive officer’s interests with those of our stockholders. Pay components and performance measures are considered by the compensation committee as fundamental financial measures of successful company performance and long-term value creation. The components of our 2019 executive compensation included:

Proxy Statement

Component	Payments	Purpose	How Determined	How it Links to Performance
Base Salary	Assured	Provides sufficient, regularly paid income to attract and retain executives with the knowledge, skills, and abilities necessary to successfully execute their job responsibilities and reflects the individual role, responsibilities, performance, and experience of each named executive officer and the importance of the role to the company.	Based on recommendation from the CEO for executives other than himself and analysis of peer company and industry compensation information. Base salary for the CEO is determined based on input from the independent compensation consultant.	Base salary is a means to attract and retain talented executives capable of driving success and performance.
Annual Cash Incentive	Performance Based At Risk	Provides an opportunity to earn annual incentive compensation to ensure focus on annual financial and operating results and to be competitive from a total renumeration standpoint.	Annual cash incentives are calculated as a percentage of base salary with payout based on the achievement of performance measures established in advance by the compensation committee.	Annual incentive performance measures are tied to the achievement of financial goals aimed to drive the success of the company and the individual business segments.
Performance Shares	Performance Based At Risk	Provides an opportunity to earn long-term compensation to ensure focus on long-term value creation and the company’s strategic objectives and to be competitive from a total renumeration standpoint.	Performance share award opportunities are recommended by the CEO for executives other than himself and approved by the compensation committee. Performance share opportunities for the CEO are determined by the compensation committee with input from the independent compensation consultant. Vesting of the awards is based on the company’s achievement of financial measures established by the compensation committee as well as total stockholder return in comparison to the company’s peer group over a three-year performance cycle.	Fosters ownership in company stock and aligns the executive’s interests with those of stockholders in increasing long-term stockholder value.

Allocation of Total Target Compensation for 2019

Total target compensation consists of base salary plus target annual and long-term incentive compensation. Performance-based incentive compensation, which consists of annual cash incentive and three-year performance share award opportunities, comprises the largest portion of our named executive officers’ total target compensation because:

• performance shares align the interests of the named executive officers with those of stockholders by making a significant portion of their target compensation contingent upon results beneficial to stockholders;

• our named executive officers are in positions of authority to drive, and therefore bear high levels of responsibility for, our corporate performance;

• variable compensation helps ensure focus on the goals that are aligned with overall company strategy; and

• incentive compensation is more variable than base salary and dependent upon company performance and the satisfaction of performance objectives.

The compensation committee generally allocates a higher percentage of total target compensation to the target long-term incentive than to the target annual incentive for our higher level executives because they are in a better position to influence long-term performance. The long-term incentive awards, if earned by achieving established measures, are paid in company common stock. These awards, combined with our stock retention requirements and our stock ownership policy, promote ownership of our stock by the executive officers. As a result, the compensation committee believes the executive officers, as stockholders, will be motivated to deliver long-term value to all stockholders.

MDU Resources Group, Inc. Proxy Statement 39

Peer Group

The compensation committee evaluates the company’s compensation plan and its performance relative to a group of peer companies in determining overall compensation and the vesting of long-term incentive compensation. The peer group is reviewed annually to assess ongoing relevance and credibility. The companies included in our 2019 peer group were evaluated and recommended by the independent compensation consultant, Meridian Compensation Partners, LLC. In evaluating potential peer companies, the compensation consultant considered companies in the construction and engineering, construction materials, and utility industries. They also sought a group of companies where MDU Resources would rank close to the 50th percentile in terms of revenues and market capitalization. In addition, the consultant considered companies currently listed as peer companies for MDU Resources by proxy advisory firms. The 2019 peer group recommended by the consultant includes eleven companies in regulated energy delivery businesses and ten companies in the construction materials or construction services businesses. At the time of analysis, MDU Resources ranked at the 54th percentile in terms of revenue and at the 41st percentile in terms of market capitalization in comparison to the selected peer group companies. The 2019 peer group reflects MDU Resources’ size, mix of current businesses, and complexity and consequently provides an appropriate group for comparative purposes.

The companies included in the 2019 peer group are shown below:

2019 Peer Companies
Regulated Energy Delivery	Construction Materials and Services
Alliant Energy Corporation	Dycom Industries, Inc.*
Ameren Corporation*	EMCOR Group, Inc.

2019 Compensation for Our Named Executive Officers

2019 Base Salary and Incentive Targets

At its November 2018 meeting, the compensation committee approved 2019 base salaries for the named executive officers. Mr. Goodin was not present during the portion of the meeting where the compensation committee discussed and approved the president and CEO base salary for 2019. At its February 2019 meeting, the compensation committee approved the target annual and long-term incentive opportunities for our named executive officers. In determining base salaries, target cash annual incentives, target long-term incentives, and total direct compensation for our named executive officers, the compensation committee received and considered company and individual performance, market and peer data, responsibilities, experience, tenure in position, internal equity, and input and recommendations from the CEO, human resources department, and the independent compensation consultant. The following information relates to each named executive officer’s 2019 base salary, target cash annual incentive, target long-term incentive, and target total direct compensation:

Mr. Goodin’s 2019 annual incentive target remained at 100% of his base salary. The compensation committee, based on recommendations from its compensation consultant, Meridian Compensation Partners, LLC, set Mr. Goodin’s long-term incentive target at $2,400,000 which is 279% of his base salary for 2019 compared to 250% in 2018.

Annual Incentives

Annual incentive awards are determined for business segment executives by the achievement of financial performance measures specific to each business segment plus a performance measure tied to overall company earnings per share. For corporate executives, annual incentive awards are determined as the sum of the weighted percentage award payouts for each business segment with the weighting based upon the business segment’s invested capital relative to the company’s total invested capital. Through this, our business segment executives are incentivized to primarily focus on the success and performance of their business segment while keeping the overall financial success of the company in mind, whereas our corporate executives are incentivized to assist in the success and performance of all lines of business.

The compensation committee selected objective financial performance measures to ensure that compensation to the executives reflects the success of their respective business segments and the company. The annual incentive performance measures for each business segment president include a corporate earnings per share performance measure representing 20% of the target award opportunity and a business segment financial performance measure representing 80% of the target award opportunity. In February 2019, the compensation committee set performance targets that it believed were rigorous based on the company’s capital and business plans, prior year results, and anticipated future market conditions. To incentivize executives to make decisions that have long-term positive impact, even at the expense of short-term results, and to prevent one-time gains and losses from having an undue impact on incentive payments, the compensation committee designed its annual incentive measures to allow for adjustments for certain unplanned events that impact our performance targets but are not indicative of underlying business performance. The following annual incentive performance measures for 2019 were adopted by the compensation committee for the business segment presidents (exclusive of the MDU Resources Group, Inc. corporate executive officers) at its February 2019 meeting:

Measure	Applies to	Purpose	Measurement	Target	Weight	How Target was Selected
MDU Resources Diluted Adjusted Earnings per Share (EPS)	All Business Segment Presidents	EPS is a generally accepted accounting principle (GAAP) measurement and is a key driver of stockholder return. This is the basis on which we provide annual performance expectations and consistent with how we report results to the financial community. This goal applies to the presidents of all business segments to engage them as members of the company’s management policy committee in the overall success of the company.	GAAP EPS (diluted) before discontinued operations plus earnings/losses from any operations discontinued after December 31, 2018, and adjustments approved by the compensation committee to remove: - the effect on earnings at the company level of intersegment earnings eliminations; - the negative effect on earnings from asset sales/dispositions/retirements; - the effect on earnings from withdrawal liabilities relating to multiemployer pension plans; - the effect on earnings from costs incurred for acquisitions and mergers; and - the effect on earnings from unanticipated changes and interpretations of tax law.	$1.45	20%	Target reflects 2019 financial goal to achieve an estimated return on invested capital of 7.4%. The 2019 target is 10 cents more than the 2018 target and 7 cents more than 2018 actual EPS before discontinued operations (diluted).
Business Segment Earnings	Electric and Natural Gas Distribution Segments President	Provides a measure of financial performance and an incentive to drive business results. Regulated entities are valued based on earnings potential and rate base.	GAAP business segment earnings before discontinued operations plus earnings/losses from any operations discontinued after December 31, 2018, and adjustments approved by the compensation committee to remove: - the negative effect on earnings from asset sales/dispositions/retirements; - the effect on earnings from transaction costs incurred for acquisitions or mergers; and - the effect on earnings from unanticipated changes and interpretations of tax law.	$91.9 million	80%	Target reflects the 2019 financial goal for the business segment. The 2019 target is 8.5% above 2018 actual results reflecting continued investment in infrastructure and revenue recovery from completed and pending rate cases.
	Pipeline and Midstream Segment President			$27.4 million	80%	Target reflects the 2019 financial goal of the business segment. The 2019 target is 14.2% above the 2018 actual results adjusted for the effects of the Tax Cuts and Jobs Act. The increase reflects anticipated revenue recovery from rate case and investment in completed projects.
Business Segment Earnings Before Interest, Tax, Depreciation, and Amortization (EBITDA)	Construction Materials and Contracting Segment President	Provides a measure of financial performance common to the industries in which these segments operate. Focusing on EBITDA encourages growth by excluding the impact of decisions regarding interest, taxes, and depreciation amortization made during the acquisition process.	EBITDA from continuing operations adjusted plus EBITDA from any operations discontinued after December 31, 2018, and adjustments approved by the compensation committee to remove: - the negative effect on earnings from asset sales/dispositions/retirements; - the effect on earnings from withdrawal liabilities relating to multiemployer plans, and - the effect on earnings from costs incurred for acquisitions or mergers.	$224.9 million	80%	Target reflects the 2019 financial goal of the business segment and is 12.7% above the actual 2018 EBITDA results. The increase reflects acquisitions completed in 2018 and backlog at 2018 year-end.
	Construction Services Segment President			$105.5 million	80%	Target reflects the 2019 financial goal of the business segment and is 1.8% above the actual 2018 EBITDA results reflecting backlog at 2018 year-end and anticipated organic and acquisition growth but offset by a return to more normal equipment sales and rental results.

Actual performance results are compared to target performance measures to arrive at a percent of target achieved. The percent of target achieved is translated into a payout percentage of the target award opportunity. Achievement of 100% of the target performance measure results in a payout of 100% of the target award opportunity. Achievement of an established threshold is required to receive partial payment of the target award opportunity. Results achieved below the established threshold result in no payout. The threshold and maximum performance as well as the associated payout opportunity are depicted in the following chart:

Measure	Weighting		Threshold				Maximum
			% of Target		Payout %		% of Target		Payout %
MDU Resources Diluted Adjusted EPS	20	%	85	%	25	%	115	%	200	%
Electric and Natural Gas Distribution Earnings	80	%	90	%	50	%	110	%	200	%

Construction Services EBITDA	80	%	65	%	25	%	115	%	250	%

Results achieved between payout levels are calculated using linear interpolation.

2019 Annual Incentive Results

The 2019 performance measure results, percent of target achieved based on those results, and the associated payout percentages reflect the company’s excellent 2019 financial performance and are presented below:

Business Segment	Performance Measure	Result	Percent of  Performance  Measure  Achieved		Percent of Award Opportunity Payout		Weight		Weighted Award  Opportunity  Payout %
All Business Segments	Earnings per Share	$1.69	116.6	%	200.0	%	20	%	40.0	%

Construction Services	EBITDA	$145.3 million	137.8	%	250.0	%	80	%	200.0	%

For our corporate named executive officers, namely Messrs. Goodin and Vollmer, the payout of the annual cash incentives is based on the achievement of performance measures at the business segments weighted by each business segment’s average invested capital relative to the company’s total invested capital. The compensation committee believes this approach provides alignment between our corporate executives and business segment performance. Messrs. Goodin’s and Vollmer’s 2019 annual cash incentives were earned at 163.2% of the target award opportunity based on the following proportional weighted sum of the annual business segment payouts:

Business Segment	Column A Business Segment Award Payout		Column B Percentage of  Average Invested Capital		Column A x Column B
Electric and Natural Gas Distribution	140.7	%	56.9	%	80.1	%
Pipeline and Midstream	163.8	%	8.7	%	14.3	%
Construction Materials and Contracting1	200.0	%	25.3	%	50.6	%
Construction Services1	200.0	%	9.1	%	18.2	%
Total Payout Percentage					163.2	%
1 For purposes of calculating the incentive awards for Messrs. Goodin and Vollmer, the award payouts associated with the construction materials and contracting and construction services segments were limited to 200%, which resulted in a weighted award payout of 200% versus 240% for the construction materials and contracting and construction services business segment presidents.

Nicole A. Kivisto	341,250	140.7	480,139

Long-Term Incentives

All our named executive officers participated in the 2019 long-term incentive plan which aligns long-term compensation with the achievement of pre-determined financial goals. Long-term incentive compensation comprised 58.2% of the CEO’s 2019 total target direct compensation and 41.6% of the average of the other named executive officer’s target total direct compensation. Stock earned under long-term incentive compensation is subject to our stock retention requirements. If the executive’s employment is terminated during the performance period for cause at any time, or for any reason other than cause before the executive has reached age 55 and completed ten years of service, all performance shares and related dividend equivalents are forfeited.

Grant of 2019-2021 Long-Term Performance Share Awards

For 2019, the compensation committee approved performance share awards which may vest at the end of a three-year period between 0% and 200% based on the achievement of three performance measures:

• Total stockholder return relative to that of the peer group companies was selected as the measure for 50% of the award vesting to align the award with the company's performance relative to our peers;

• Compound annual growth rate in EBITDA from continuing operations was selected as the measure for 25% of the award vesting to encourage strategic growth and focuses on controllable costs; and

• Compound annual growth rate in earnings from continuing operations was selected as the measure for 25% of the award vesting to encourage quality earnings and continued growth of the company.

For the awards made in 2019, earnings used to calculate EBITDA growth may be adjusted, as such adjustments are approved by the compensation committee, to remove:

• the effect on earnings from leases/impairments on asset sales/dispositions/retirements;

• the effect on earnings from withdrawal liabilities relating to multiemployer pension plans; and

• the effect on earnings from costs incurred for acquisitions or mergers.

Earnings used to calculate earnings growth from continuing operations for the 2019 awards may be adjusted, as approved by the compensation committee, to remove the effects on earnings as noted above for the calculation of EBITDA growth plus any effect on earnings from unanticipated tax law changes.

Vesting of shares and associated dividend equivalents is predicated on achievement of an established threshold associated with each performance measure. To safeguard the confidentiality of our long-term outlook on projected performance outcomes, we do not disclose actual performance targets until the performance period is completed. Achievement of the threshold of the performance measure results in vesting of 20% of the associated portion of the performance share award. Actual results of the performance measure achieved below the threshold lead to zero vesting of the associated portion of the performance share award. Maximum performance measure levels have also been established for each performance measure and result in vesting of 200% of the associated portion of the performance share award. Thresholds and maximum payouts as a percentage of target performance for the 2019 measures are:

On February 14, 2019, for the 2019-2021 performance period, the compensation committee determined the target number of performance shares for each named executive officer by dividing a selected target long-term award amount by the average of the closing prices of our stock from January 1 through January 22, 2019, which was $24.29 per share. Based on this price, the compensation committee awarded the following target performance share opportunities to the named executive officers:

Name	Base Salary ($)	Target Long-Term Performance Share Incentive % of Base Salary (%)	Long-Term Performance Share Incentive Target ($)	Performance Share Opportunities (#)
David L. Goodin	860,000	279	2,400,000	98,806

Nicole A. Kivisto	455,000	129	585,000	24,083

Vesting of 2017-2019 Performance Share Awards

For the 2017-2019 performance period, the long-term incentive program consisted solely of performance shares. The performance criteria used for the 2017-2019 performance period was total stockholder return as a percentile of the total stockholder return for our peer companies over the three-year performance period.

Our total stockholder return ranking over the performance period was at the 26th percentile which resulted in vesting at 23% of the target performance shares and dividend equivalents. The named executive officers received the following long-term compensation for the 2017-2019 performance period:

Name	Target Performance Shares (#)	Performance Shares Vested (#)	Dividend Equivalents ($)
David L. Goodin	61,890	14,234	33,948
Jason L. Vollmer	3,912	899	2,144
David C. Barney	13,338	3,067	7,315
Jeffrey S. Thiede	13,670	3,144	7,498
Nicole A. Kivisto	11,804	2,714	6,473

Stock Retention Requirement

The named executive officers must retain 50% of the net after-tax shares vested pursuant to the long-term incentive awards for the earlier of two years from the date the vested shares are issued or the executive’s termination of employment. The executive officer is also required to retain share awards net of taxes if the executive has not met the stock ownership requirements under the company’s stock ownership policy for executives.

Other Benefits

The company provides post-employment benefit plans and programs in which our named executive officers may be participants. We believe it is important to provide post-employment benefits which approximate retirement benefits paid by other employers to executives in similar positions. The compensation committee periodically reviews the benefits provided to maintain a market-based benefits package. Our named executive officers participated in the following plans during 2019 which are described below:

Plans	David L. Goodin	Jason L. Vollmer	David C. Barney	Jeffrey S. Thiede	Nicole A. Kivisto
401(k) Retirement Plan	Yes	Yes	Yes	Yes	Yes
Pension Plans	Yes	Yes	No	No	Yes
Supplemental Income Security Plan	Yes	No	Yes	No	Yes
Nonqualified Defined Contribution Plan	No	Yes	Yes	Yes	No

401(k) Retirement Plan

The named executive officers as well as all employees working a minimum of 1,000 hours per year are eligible to participate in the 401(k) plan and defer annual income up to the IRS limit. The company provides a match up to 3% depending on the employee’s elected deferral rate. Contributions and the company match are invested in various funds based on the employee’s election including company common stock.

In 2010, the company began offering increased company contributions to our 401(k) plan in lieu of pension plan contributions. For non-bargaining unit employees hired after 2006 or employees who were not previously participants in the pension plan, the added retirement contribution is 5% of plan eligible compensation. For non-bargaining unit employees hired prior to 2006 who were participants in the pension plan, the added retirement contributions are based on the employee’s age as of December 31, 2009. The retirement contribution is 11.5% for Mr. Goodin,9.0% for Ms. Kivisto, 7.0% for Mr. Vollmer, and 5.0% for Messrs. Barney and Thiede. These amounts may be reduced in accordance with the provisions of the 401(k) plan to ensure compliance with IRS limits.

Pension Plans

Effective in 2006, the defined benefit pension plans were closed to new non-bargaining unit employees and as of December 31, 2009, the defined benefit plans were frozen. For further details regarding the company’s pension plans, please refer to the section entitled “Pension Benefits for 2019.”

Supplemental Income Security Plan

We offered certain key managers and executives benefits under a nonqualified retirement plan referred to as the Supplemental Income Security Plan (SISP). The SISP provides participants with additional retirement income and death benefits. Effective February 11, 2016, the SISP was amended to exclude new participants to the plan and freeze current benefit levels for existing participants. For further details regarding the company’s SISP, please refer to the section entitled “Pension Benefits for 2019.” Named executive officers participating in the SISP are Messrs. Goodin and Barney and Ms. Kivisto.

The following table reflects our named executive officers’ SISP benefits as of December 31, 2019:

Nonqualified Defined Contribution Plan

The company adopted the Nonqualified Defined Contribution Plan (NQDCP) effective January 1, 2012, to provide retirement and deferred compensation for a select group of management and other highly compensated employees. The compensation committee, upon recommendation from the CEO, annually determines which employees will participate in the NQDCP and the amount of contributions for each participant. After satisfying a vesting requirement for each contribution, distributions will be made in accordance with the terms of the plan. For further details regarding the company’s NQDCP, please refer to the section entitled “Nonqualified Deferred Compensation for 2019.”

For 2019, the compensation committee selected and approved contributions of $40,000 to Mr. Vollmer, $150,000 to Mr. Barney, and $100,000 to Mr. Thiede. The contributions awarded to Messrs. Vollmer, Barney, and Thiede represent 10.00%, 32.02%, and 21.34% of their base salaries, respectively.

Employment and Severance Agreements

We currently do not have employment or severance agreements with our executives entitling them to specific payments upon termination of employment or a change of control of the company. The compensation committee generally considers providing severance benefits on a case-by-case basis. Any post-employment or change of control benefits available to our executives are addressed within our incentive and retirement plans. Please refer to the section entitled “Potential Payments upon Termination or Change of Control.”

Compensation Governance

Impact of Tax and Accounting Treatment

The compensation committee may consider the impact of tax and/or accounting treatment in determining compensation.

Section 162(m) of the Internal Revenue Code limits the deductibility of certain compensation to $1 million paid to certain officers as a business expense in any tax year. The federal Tax Cuts and Jobs Act (Tax Reform), signed into law in December 2017, expanded the number of individuals covered by the Section 162(m) deductibility limit and repealed the exception for performance-based compensation, effective for taxable years beginning after December 31, 2017. Incentive compensation approved by the compensation committee prior to Tax Reform for our CEO and those executive officers whose overall compensation was likely to exceed $1 million was generally structured to meet the requirements for the performance-based exception for deductibility for purposes of Section 162(m). As a result of Tax Reform, compensation paid to our covered executive officers in excess of $1 million will not be deductible, unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017. The compensation committee believes the tax deduction limitation should not compromise its responsibility to design and maintain a compensation program that will attract and retain the executive talent necessary to successfully execute the company’s strategy.

The compensation committee also considers the accounting and cash flow implications of various forms of executive compensation. We expense salaries and annual incentive compensation as earned. For our equity awards, we record the accounting expense in accordance with Financial Accounting Standards Board 718, which is generally expensed over the vesting period.

Stock Ownership Requirements

Executives participating in our Long-Term Performance-Based Incentive Plan are required within five years of appointment or promotion into an executive level to beneficially own our common stock equal to a multiple of their base salary as outlined in the stock ownership policy. Stock owned through our 401(k) plan or by a spouse is considered in ownership calculations. The level of stock ownership compared to the ownership requirement is determined based on the closing sale price of our stock on the last trading day of the year and base salary at December 31 of the same year. The table shows the named executive officers’ holdings as a multiple of their base salary.

Name	Ownership Policy Multiple of Base Salary Within 5 Years	Actual Holdings as a Multiple of Base Salary1	Ownership Requirement Must Be Met By:

Deferral of Annual Incentive Compensation

We provide executives the opportunity to defer receipt of earned annual incentives. If an executive chooses to defer all or part of an annual incentive, we credit the deferral with interest at a rate determined by the compensation committee. For 2019, the interest rate for deferrals was 4.4% based on an average of the Moody’s U.S. Long-Term Corporate Bond Yield Average for “A” and “Baa” rated companies. The compensation committee’s reasons for using this interest rate recognized incentive deferrals are a low-cost source of capital for the company and are unsecured obligations and, therefore, carry an associated level of risk to the executives.

Clawback

In February 2016, we amended our Long-Term Performance-Based Incentive Plan and Executive Incentive Compensation Plan sections regarding the repayment of incentive compensation due to accounting restatements, commonly referred to as a clawback policy. The compensation committee may, or shall if required, take action to recover incentive-based compensation from specific executives in the event the company is required to restate its financial statements due to material noncompliance with any financial reporting requirements under the securities laws.

Policy Regarding Hedging Stock Ownership

Our executive compensation policy prohibits executive officers, which includes our named executive officers, from hedging their ownership of company common stock. Executives may not enter into transactions that allow the executive to benefit from devaluation of our stock or otherwise own stock technically but without the full benefits and risks of such ownership. See the section entitled “Security Ownership” for our policy on margin accounts and pledging of our stock.

COMPENSATION COMMITTEE REPORT

The compensation committee is primarily responsible for reviewing, approving, and overseeing the company’s compensation plans and practices and works with management and the committee’s independent compensation consultant to develop the company executive compensation programs. The compensation committee has reviewed and discussed the Compensation Discussion and Analysis required by Regulation S-K, Item 402(b), with management. Based on the review and discussions referred to in the preceding sentence, the compensation committee recommended to the board of directors that the Compensation Discussion and Analysis be included in our Proxy Statement on Schedule 14A.

Narrative Discussion Relating to the Summary Compensation Table
and Grants of Plan-Based Awards Table

Annual Incentive

The compensation committee recommended the 2019 annual incentive award opportunities for our named executive officers and the board approved these opportunities at its meeting on February 14, 2019. The award opportunities at threshold, target, and maximum are reflected in columns (c), (d), and (e), respectively, of the Grants of Plan-Based Awards Table. The actual amount paid with respect to 2019 performance is reflected in column (g) of the Summary Compensation Table.

As described in the “Annual Incentives” section of the “Compensation Discussion and Analysis,” payment of annual award opportunities is dependent upon achievement of performance measures; actual payout may range from 0% to 200% of the target except for the construction materials and contracting and construction services segments which may range from 0% to 240%.

All our named executive officers were awarded their annual incentive opportunities pursuant to the MDU Resources Group, Inc. Executive Incentive Compensation Plan. Under the Executive Incentive Compensation Plan, executives who retire during the year at or after age 65 remain eligible to receive an award, but executives who terminate employment for other reasons are not eligible for an award. The compensation committee generally does not modify the performance measures; however, if in years of unusually adverse or favorable external conditions or other unforeseen significant factors beyond the control of management, the compensation committee may modify the performance measures. The compensation committee has full discretion to determine the extent to which goals have been achieved, the payment level, and whether to adjust payment of awards downward based upon individual performance. For further discussion of the specific 2019 incentive plan performance measures and results, see the “Annual Incentives” section in the “Compensation Discussion and Analysis.”

Long-Term Incentive

The compensation committee recommended long-term incentive award opportunities for the named executive officers in the form of performance shares, and the board approved the award opportunities at its meeting on February 14, 2019. The long-term incentive opportunities are presented as the number of performance shares at threshold, target, and maximum in columns (f), (g), and (h) of the Grants of Plan-Based Awards Table. The value of the long-term performance-based incentive opportunities is based on the aggregate grant date fair value and is reflected in column (e) of the Summary Compensation Table and column (l) of the Grant of Plan-Based Awards Table.

Depending on the achievement of the performance measures associated with our 2019-2021 performance period, executives will receive from 0% to 200% of the target awards in February 2022. We also will pay dividend equivalents in cash on the number of shares actually vested for the performance period. The dividend equivalents will be paid in 2022 at the same time as the performance share awards are settled.

Nonqualified Defined Contribution Plan

The CEO recommends participants and contribution amounts to the Nonqualified Defined Contribution Plan which are approved by the compensation committee of the board of directors. The purpose of the plan is to recognize outstanding performance coupled with enhanced retention as the Nonqualified Defined Contribution Plan requires a vesting period. The amount shown in column (i) - All Other Compensation of the Summary Compensation Table includes contributions of $40,000 to Mr. Vollmer, $150,000 to Mr. Barney, and $100,000 to Mr. Thiede. For further information, see the section entitled “Nonqualified Deferred Compensation for 2019.”

54 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

The amounts shown for the pension plan, Basic SISP, and Excess SISP represent the actuarial present values of the executives’ accumulated benefits accrued as of December 31, 2019, calculated using:

• a 2.71% discount rate for the Basic SISP and Excess SISP;

• a 2.93% discount rate for the pension plan;

• the Society of Actuaries PRi-2012 Total Dataset Mortality with Scale MP-2019 (post commencement only); and

• no recognition of future salary increases or pre-retirement mortality.

The actuary assumed a retirement age of 60 for the pension, Basic SISP, and Excess SISP benefits and assumed retirement benefits commence at age 60 for the pension and Excess SISP and age 65 for Basic SISP benefits.

Pension Plan

The MDU Resources Group, Inc. Pension Plan for Non-Bargaining Unit Employees (pension plan) applies to employees hired before 2006 and was amended to cease benefit accruals as of December 31, 2009. The benefits under the pension plan are based on a participant’s average annual salary over the 60 consecutive month period where the participant received the highest annual salary between 1999 and 2009. Benefits are paid as straight life annuities for single participants and as actuarially reduced annuities with a survivor benefit for married participants unless they choose otherwise.

Supplemental Income Security Plan

The Supplemental Income Security Plan (SISP), a nonqualified defined benefit retirement plan, is offered to select key managers and executives. SISP benefits are determined by reference to levels defined within the plan. Our compensation committee, after receiving recommendations from our CEO, determined each participant’s level within the plan. On February 11, 2016, the SISP was amended to exclude new participants to the plan and freeze current benefit levels for existing participants.

Basic SISP Benefits

Basic SISP is a supplemental retirement benefit intended to augment the retirement income provided under the pension plans. The Basic SISP benefits are subject to the following ten-year vesting schedule:

• 0% vesting for less than three years of participation;

• 20% vesting for three years of participation;

• 40% vesting for four years of participation; and

• an additional 10% vesting for each additional year of participation up to 100% vesting for ten years of participation.

Participants can elect to receive the Basic SISP as:

• monthly retirement benefits only;

• monthly death benefits paid to a beneficiary only; or

• a combination of retirement and death benefits, where each benefit is reduced proportionately.

Regardless of the election, if the participant dies before the SISP retirement benefit commences, only the SISP death benefit is provided.

Excess SISP Benefits

Excess SISP is an additional retirement benefit relating to Internal Revenue Code limitations on retirement benefits provided under the pension plans. Excess SISP benefits are equal to the difference between the monthly retirement benefits that would have been payable to the participant under the pension plans absent the limitations under the Internal Revenue Code and the actual benefits payable to the participant under the pension plans. Participants are only eligible for the Excess SISP benefits if the participant is fully vested under the pension plan, their employment terminates prior to age 65, and benefits under the pension plan are reduced due to limitations under the Internal Revenue Code on plan compensation.

In 2009, the SISP was amended to limit eligibility for the Excess SISP benefit. Mr. Goodin is the only named executive officer eligible for the Excess SISP benefit and must remain employed with the company until age 60 in order to receive the benefit. Benefits generally commence six months after the participant’s employment terminates and continue to age 65 or until the death of the participant, if prior to age 65.

Both Basic and Excess SISP benefits are forfeited if the participant’s employment is terminated for cause.

MDU Resources Group, Inc. Proxy Statement 55

Nonqualified Deferred Compensation for 2019

Deferred Annual Incentive Compensation

Executives participating in the annual incentive compensation plans may elect to defer up to 100% of their annual incentive awards. Deferred amounts accrue interest at a rate determined by the compensation committee. The interest rate in effect for 2019 was 4.4% based on an average of the Moody’s U.S. Long-Term Corporate Bond Yield Average for “A” and “Baa” rated companies. The deferred amount will be paid in accordance with the participant’s election, following termination of employment or beginning in the fifth year following the year the award was earned. The amounts are paid in accordance with the participant’s election in either a lump sum or in monthly installments not to exceed 120 months. In the event of a change of control, all amounts deferred would immediately become payable. For purposes of deferred annual incentive compensation, a change of control is defined as:

• an acquisition during a 12-month period of 30% or more of the total voting power of our stock;

• an acquisition of our stock that, together with stock already held by the acquirer, constitutes more than 50% of the total fair market value or total voting power of our stock;

• replacement of a majority of the members of our board of directors during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of our board of directors; or

• acquisition of our assets having a gross fair market value at least equal to 40% of the gross fair market value of all of our assets.

Nonqualified Defined Contribution Plan

The company adopted the Nonqualified Defined Contribution Plan, effective January 1, 2012, to provide deferred compensation for a select group of employees. The compensation committee approves the amount of employer contributions under the Nonqualified Defined Contribution Plan and the obligations under the plan constitute an unsecured promise of the company to make such payments. The company credits contributions to plan accounts which capture the hypothetical investment experience based on the participant’s elections. Contributions made prior to 2017 vest four years after each contribution in accordance with the terms of the plan. Contributions made in and after 2017 vest rateably over a three-year period with one-third vesting after the first year, an additional one-third after the second year, and the final one-third after the third year. Amounts shown as aggregate earnings in the table below for Messrs. Vollmer, Barney, and Thiede reflect the change in investment value at market rates for the hypothetical investments selected by the participants. Participants may elect to receive their vested contributions and investment earnings either in a lump sum upon separation from service with the company or in annual installments over a period of years upon the later of (i) separation from service and (ii) age 65. Plan benefits become fully vested if the participant dies while actively employed. Benefits are forfeited if the participant’s employment is terminated for cause.

The table below includes individual contributions from deferrals of annual incentive compensation and company contributions under the Nonqualified Defined Contribution Plan:

Potential Payments upon Termination or Change of Control

The Potential Payments upon Termination or Change of Control Table shows the payments and benefits our named executive officers would receive in connection with a variety of employment termination scenarios or upon a change of control. The scenarios include:

• Voluntary Termination;

• Not for Cause Termination;

• Death;

• Disability;

• Change of Control with Termination; and

• Change of Control without Termination.

For the named executive officers, the information assumes the terminations or the change of control occurred on December 31, 2019.

The table excludes compensation and benefits our named executive officers would earn during their employment with us whether or not a termination or change of control event had occurred. The tables also do not include benefits under plans or arrangements generally available to all salaried employees and that do not discriminate in favor of the named executive officers, such as benefits under our qualified defined benefit pension plan (for employees hired before 2006), accrued vacation pay, continuation of health care benefits, and life insurance benefits. The tables also do not include Nonqualified Defined Contribution Plan or deferred annual compensation amounts which are shown and explained in the Nonqualified Deferred Compensation for 2019 Table.

Compensation

None of our named executive officers have employment or severance agreements entitling them to their base salary, some multiple of base salary or severance upon termination or change of control. Our compensation committee generally considers providing severance benefits on a case-by-case basis. Because severance payments are discretionary, no amounts are presented in the tables.

All our named executive officers were granted their 2019 annual incentive award under the Executive Incentive Compensation Plan (EICP) which has no change of control provision in regards to annual incentive compensation other than for deferred compensation. The EICP requires participants to remain employed with the company through the service year to be eligible for a payout unless otherwise determined by the compensation committee for named executive officers or employment termination after age 65. As all our scenarios assume a termination or change in control event on December 31st, the named executives officers would be considered employed for the entire performance period; therefore, no amounts are shown for annual incentives in the tables for our named executive officers, as they would be eligible to receive their annual incentive award based on the level that performance measures were achieved for the performance period regardless of termination or change of control occurring on December 31, 2019.

All named executive officers received their performance share awards under the Long-Term Performance-Based Incentive Plan (LTIP). Upon a change of control (with or without termination), performance share awards would be deemed fully earned and vest at their target levels for the named executive officers. For this purpose, the term “change of control” is defined in the LTIP as:

• the acquisition by an individual, entity, or group of 20% or more of our outstanding common stock;

• a majority of our board of directors whose election or nomination was not approved by a majority of the incumbent board members;

• consummation of a merger or similar transaction or sale of all or substantially all of our assets, unless our stockholders immediately prior to the transaction beneficially own more than 60% of the outstanding common stock and voting power of the resulting corporation in substantially the same proportions as before the merger, no person owns 20% or more of the resulting corporation’s outstanding common stock or voting power except for any such ownership that existed before the merger and at least a majority of the board of the resulting corporation is comprised of our directors; or

• stockholder approval of our liquidation or dissolution.

MDU Resources Group, Inc. Proxy Statement 57

Proxy Statement

For termination scenarios other than a change of control, our award agreements provide that performance share awards are forfeited if the participant’s employment terminates before the participant has reached age 55 and completed 10 years of service. If a participant’s employment is terminated other than for cause after reaching age 55 and completing 10 years of service, performance shares are prorated as follows:

• termination of employment during the first year of the performance period = shares are forfeited;

• termination of employment during the second year of the performance period = performance shares earned are prorated based on the number of months employed during the performance period; and

• termination of employment during the third year of the performance period = full amount of any performance shares earned are received.

Under the termination scenarios, Messrs. Goodin, Barney, and Thiede would receive performance shares as they have each reached age 55 and have 10 or more years of service. The number of performance shares received would be based on the following:

• 2017-2019 performance shares would vest based on the achievement of the performance measure for the period ended December 31, 2019, which was 23%;

• 2018-2020 performance shares would be prorated at 24 out of 36 months (2/3) of the performance period and vest based on the actual achievement of the performance measure for the period ended December 31, 2020. For purposes of the Potential Payments upon Termination or Change of Control Table, the vesting is shown at 100%; and

• 2019-2021 performance shares would be forfeited.

For purposes of calculating the performance share value shown in the Potential Payments upon Termination or Change of Control Table, the number of vesting shares was multiplied by the average of the high and low stock price for the last market day of the year, which was December 31, 2019. Dividend equivalents based on the number of vesting shares are also included in the amounts presented.

Neither Ms. Kivisto nor Mr. Vollmer have reached age 55; therefore, they are not eligible for vesting of performance shares in the event of their termination.

Messrs. Barney and Thiede were granted 11,419 restricted stock units in February 2018. The restricted stock units will vest on December 31, 2020, provided that Messrs. Barney and Thiede remain continuously employed by the company through December 31, 2020, except for termination due to death or disability or a change in control as defined in the LTIP. In the case of a voluntary or not for cause termination on December 31, 2019, Messrs Barney and Thiede would forfeit the restricted stock units. In the case of death or disability, the restricted stock units would vest based on the number of full months of employment completed during the grant period to the date of death or disability divided by the total number of months in the grant period. In the case of death or disability occurring on December 31, 2019, two-thirds of Messrs. Barney and Thiede’s restricted stock units plus dividend equivalents would vest. In the case of a change of control (with or without termination) occurring on December 31, 2019, the restricted stock units plus dividend equivalents would fully vest.

Benefits and Perquisites

Supplemental Income Security Plan

As described in the “Pension Benefits for 2019” section, the Basic SISP provides a benefit of payments commencing at the latter of retirement or age 65 and payable for 15 years. Of the named executive officers, only Messrs. Goodin, Barney, and Ms. Kivisto participate in the Basic SISP benefits. While Messrs. Goodin and Barney are 100% vested in their SISP benefit, Ms. Kivisto entered the plan in 2011 and is only 90% vested in her SISP benefit at December 31, 2019. Ms. Kivisto received a benefit level upgrade in 2014, which cliff vests on January 1, 2021. This means that if her employment terminates for any reason other than death before January 1, 2021, her benefit upgrade is forfeited.

Under all scenarios except death and change of control without termination, the payment represents the present value of the vested Basic SISP benefit as of December 31, 2019, using the monthly retirement benefit shown in the table below and a discount rate of 2.71%. In the event of death, Messrs. Goodin, Barney, and Ms. Kivisto’s beneficiaries would receive monthly death benefit payments for 15 years. The Potential Payments upon Termination or Change of Control Table shows the present value calculations of the monthly death benefit using the 2.71% discount rate.

*	Ms. Kivisto’s calculations are based on 90% of the value shown above for voluntary, not for cause and change of control with termination scenarios. The disability scenario allows for two additional years of vesting and is calculated using 100% of the value shown above. Ms. Kivisto’s death benefit scenario is calculated using her 2014 benefit upgrade level with a monthly death benefit of $13,144.

Because the plan requires a participant to be no longer actively employed by the company in order to be eligible for payments, we do not show benefits for the change of control without termination scenario.

Disability

We provide disability benefits to some of our salaried employees equal to 60% of their base salary, subject to a salary limit of $200,000 for officers and $100,000 for other salaried employees when calculating benefits. For all eligible employees, disability payments continue until age 65 if disability occurs at or before age 60 and for five years if disability occurs between the ages of 60 and 65. Disability benefits are reduced for amounts paid as retirement benefits. The disability payments in the Potential Payments upon Termination or Change of Control Table reflect the present value of the disability benefits attributable to the additional $100,000 of base salary recognized for executives under our disability program, subject to the 60% limitation, after reduction for amounts that would be paid as retirement benefits. For Messrs. Goodin and Vollmer and Ms. Kivisto, who participate in the pension plan, the amount represents the present value of the disability benefit after reduction for retirement benefits using a discount rate of 2.93%. Because Mr. Goodin’s retirement benefit is greater than the disability benefit, the amount shown is zero. For Messrs. Barney and Thiede, who do not participate in the pension plan, the amount represents the present value of the disability benefit without reduction for retirement benefits using the discount rate of 2.71%, which is considered a reasonable rate for purposes of the calculation.

CEO Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing information regarding the relationship of the annual total compensation of David L. Goodin, our president and chief executive officer, to the annual total compensation of our median employee.

Our employee workforce fluctuates during the year largely depending on the seasonality, number, and size of construction project activity conducted by our businesses. Approximately 51% of our employee workforce is employed under union bargained labor contracts which define compensation and benefits for participants which may include payments made by the company associated with employee participation in union benefit and pension plans.

We identified the median employee by examining the 2019 taxable wage information for all individuals on the company’s payroll records as of December 31, 2019, excluding Mr. Goodin. All of the company’s employees are located in the United States. We made no adjustments to annualize compensation for individuals employed for only part of the year. We selected taxable wages as reported to the Internal Revenue Service on Form W-2 for 2019 to identify the median employee as it includes substantially all of the compensation for our median employee and provided a reasonably efficient and cost-effective manner for the identification of the median employee. Our median employee is a member of a union and works for a subsidiary of our construction services segment; he does not participate in our pension or 401(k) plan.

Once identified, we categorized the median employee’s compensation to correspond to the compensation components as reported in the Summary Compensation Table. For 2019, the total annual compensation of Mr. Goodin as reported in the Summary Compensation Table included in this Proxy Statement was $6,144,355, and the total annual compensation of our median employee was $63,768. Based on this information, the 2019 ratio of annual total compensation of Mr. Goodin to the median employee was 96 to 1.

AUDIT MATTERS

ITEM 3: RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2020

The audit committee at its February 2020 meeting appointed Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2020. The board of directors concurred with the audit committee’s decision. Deloitte & Touche LLP has served as our independent registered public accounting firm since fiscal year 2002.

Although your ratification vote will not affect the appointment or retention of Deloitte & Touche LLP for 2020, the audit committee will consider your vote in determining its appointment of our independent registered public accounting firm for the next fiscal year. The audit committee, in appointing our independent registered public accounting firm, reserves the right, in its sole discretion, to change an appointment at any time during a fiscal year if it determines that such a change would be in our best interests.

A representative of Deloitte & Touche LLP will be present at the annual meeting and will be available to respond to appropriate questions. We do not anticipate that the representative will make a prepared statement at the annual meeting; however, he or she will be free to do so if he or she chooses.

The board of directors recommends a vote “for” the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2020.

Ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2020 requires the affirmative vote of a majority of our common stock present in person or represented by proxy at the annual meeting and entitled to vote on the proposal. Abstentions will count as votes against this proposal.

Annual Evaluation and Selection of Deloitte & Touche LLP

The audit committee annually evaluates the performance of its independent registered public accounting firm, including the senior audit engagement team, and determines whether to re-engage the current independent accounting firm or consider other firms. Factors considered by the audit committee in deciding whether to retain the current independent accounting firm include:

• Deloitte & Touche LLP’s capabilities considering the complexity of our business and the resulting demands placed on Deloitte & Touche LLP in terms of technical expertise and knowledge of our industry and business;

• the quality and candor of Deloitte & Touche LLP’s communications with the audit committee and management;

• Deloitte & Touche LLP’s independence;

• the quality and efficiency of the services provided by Deloitte & Touche LLP, including input from management on Deloitte & Touche LLP’s performance and how effectively Deloitte & Touche LLP demonstrated its independent judgment, objectivity, and professional skepticism;

• external data on audit quality and performance, including recent Public Company Accounting Oversight Board reports on Deloitte & Touche LLP and its peer firms; and

• the appropriateness of Deloitte & Touche LLP’s fees, tenure as our independent auditor, including the benefits of a longer tenure, and the controls and processes in place that help ensure Deloitte & Touche LLP’s continued independence.

Based on this evaluation, the audit committee and the board believe that retaining Deloitte & Touche LLP to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2020, is in the best interests of our company and its stockholders.

In accordance with rules applicable to mandatory partner rotation, Deloitte & Touche LLP’s lead engagement partner for our audit was changed in 2017. The audit committee oversees the process for, and ultimately approves, the selection of the lead engagement partner.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of the Independent Registered Public Accounting Firm

The audit committee pre-approved all services Deloitte & Touche LLP performed in 2019 in accordance with the pre-approval policy and procedures the audit committee adopted in 2003. This policy is designed to achieve the continued independence of Deloitte & Touche LLP and to assist in our compliance with Sections 201 and 202 of the Sarbanes-Oxley Act of 2002 and related rules of the SEC.

The policy defines the permitted services in each of the audit, audit-related, tax, and all other services categories, as well as prohibited services. The pre-approval policy requires management to submit annually for approval to the audit committee a service plan describing the scope of work and anticipated cost associated with each category of service. At each regular audit committee meeting, management reports on services performed by Deloitte & Touche LLP and the fees paid or accrued through the end of the quarter preceding the meeting. Management may submit requests for additional permitted services before the next scheduled audit committee meeting to the designated member of the audit committee, currently David M. Sparby, for approval. The designated member updates the audit committee at the next regularly scheduled meeting regarding any services approved during the interim period. At each regular audit committee meeting, management may submit to the audit committee for approval a supplement to the service plan containing any request for additional permitted services.

In addition, prior to approving any request for audit-related, tax, or all other services of more than $50,000, Deloitte & Touche LLP will provide a statement setting forth the reasons why rendering of the proposed services does not compromise Deloitte & Touche LLP’s independence. This description and statement by Deloitte & Touche LLP may be incorporated into the service plan or included as an exhibit thereto or may be delivered in a separate written statement.

AUDIT COMMITTEE REPORT

The audit committee assists the board in fulfilling its oversight responsibilities and serves as a communication link among the board, management, the independent auditors, and the internal auditors. The audit committee (a) assists the board’s oversight of (i) the integrity of the company’s financial reporting process and system of internal controls, (ii) the company’s compliance with legal and regulatory requirements and the code of conduct, (iii) the independent auditors’ qualifications and independence, (iv) the performance of the company’s internal audit function and independent auditors, and (v) the company’s management of risks in the audit committee’s areas of responsibility; (b) arranges for the preparation of and approves the report that SEC rules require be included in the company’s annual proxy statement; (c) is also responsible for the appointment, compensation, retention, and oversight of the independent auditors including pre-approval of all audit and non-audit services by the independent auditors. The audit committee acts under a written charter which it reviews at least annually and a copy of which is available on our website.

Management has primary responsibility for the company’s financial statements and the reporting process, including the systems of internal control over financial reporting. The independent auditors are responsible for performing an independent audit of the company’s consolidated financial statements, issuing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, and assessing the effectiveness of the company’s internal controls over financial reporting. The audit committee oversees the company’s financial reporting process and internal controls on behalf of the board.

In performing its oversight responsibilities in connection with our financial statements for the year ended December 31, 2019, the audit committee:

• reviewed and discussed the audited financial statements with management;

• discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC;

• received the written disclosures and the letter from the independent auditors required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent auditors’ communications with the audit committee concerning independence, and discussed with the independent auditors their independence; and

• reviewed and pre-approved the services provided by the independent auditors other than their audit services and considered whether the provision of such other services by our independent auditors is compatible with maintaining their independence.

Based on the review and discussions referred to above, the audit committee recommended to the board of directors, and the board of directors has approved, that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2019, for filing with the SEC. The audit committee has appointed Deloitte & Touche LLP as the company’s independent auditors for 2020. Stockholder ratifications of this appointment is included as Item 3 in these proxy materials.
