You may vote your shares by telephone, by the Internet, or by returning the enclosed proxy card. Representation of your shares at the meeting is very important. We urge you to submit your proxy promptly.

All stockholders who find it convenient to do so are cordially invited and urged to attend the meeting in person. Registered stockholders will receive a request for admission ticket(s) with their proxy card that can be completed and returned to us postage-free. Stockholders whose shares are held in the name of a bank or broker will not receive a request for admission ticket(s). They should, instead, (1) call (701) 530-1000 to request an admission ticket(s), (2) bring a statement from their bank or broker showing proof of stock ownership as of March 2, 2015, to the annual meeting, and (3) present their admission ticket(s) and photo identification, such as a driver’s license.

Proxy Statement

PROXY STATEMENT

The board of directors of MDU Resources Group, Inc. is furnishing this proxy statement beginning March 18, 2015, to solicit your proxy for use at our annual meeting of stockholders on April 28, 2015, and any adjournment(s) thereof. We are soliciting proxies principally by mail, but directors, officers, and employees of MDU Resources Group, Inc. or its subsidiaries may solicit proxies personally, by telephone, or by electronic media, without compensation other than their regular compensation. Okapi Partners LLC additionally will solicit proxies for approximately $8,000 plus out-of-pocket expenses. We will pay the cost of soliciting your proxy and reimburse brokers and others for forwarding proxy materials to you.

The Securities and Exchange Commission’s e-proxy rules allow companies to post their proxy materials on the Internet and provide only a Notice of Internet Availability of Proxy Materials to stockholders as an alternative to mailing full sets of proxy materials except upon request. For 2015, we have elected to use the Securities and Exchange Commission’s full set delivery option, which means that while we are posting our proxy materials online, we are also mailing a full set of our proxy materials to our stockholders. We believe that mailing a full set of proxy materials will help ensure that a majority of outstanding shares of our common stock are present in person or represented by proxy at our meeting. We also hope to help maximize stockholder participation. Therefore, even if you previously consented to receiving your proxy materials electronically, you will receive a full set of proxy materials in the mail for this year’s annual meeting. However, we will continue to evaluate the option of providing only a Notice of Internet Availability of Proxy Materials to some or all of our stockholders in the future.

VOTING INFORMATION

Who may vote? You may vote if you owned shares of our common stock at the close of business on March 2, 2015. You may vote each share that you owned on that date on each matter presented at the meeting and any adjournment(s) thereof. As of March 2, 2015, we had 194,597,172 shares of common stock outstanding entitled to one vote per share.

What am I voting on? You are voting on:

•election of ten directors nominated by the board of directors for one-year terms

•ratification of the appointment of Deloitte & Touche LLP as the company’s independent registered public accounting firm for 2015

•approval, on a non-binding advisory basis, of the compensation of the company’s named executive officers and

•any other business that is properly brought before the meeting or any adjournment(s) thereof.

What vote is required to pass an item of business? A majority of our outstanding shares of common stock entitled to vote must be present in person or represented by proxy to hold the meeting.

If you hold shares through an account with a bank or broker, the bank or broker may vote your shares on some matters even if you do not provide voting instructions. Brokerage firms have the authority under the New York Stock Exchange rules to vote shares on certain matters when their customers do not provide voting instructions. However, on other matters, when the brokerage firm has not received voting instructions from its customers, the brokerage firm cannot vote the shares on those matters and a “broker non-vote” occurs. This means that brokers may not vote your shares on items 1 and 3 if you have not given your broker specific instructions as to how to vote. Please be sure to give specific voting instructions to your broker so that your vote can be counted.

Item 1 – Election of Directors

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, directors will be elected by a plurality of the votes cast. 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.

MDU Resources Group, Inc. Proxy Statement 1

Proxy Statement

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.

Item 2 – Ratification of the Appointment of Deloitte & Touche LLP as the Company’s Independent Registered Public Accounting Firm for 2015

Approval of Item 2 requires the affirmative vote of a majority of our 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” the proposal.

Item 3 – Approval, on a Non-Binding Advisory Basis, of the Compensation of the Company’s Named Executive Officers

Approval of Item 3 requires the affirmative vote of a majority of our common stock present in person or represented by proxy at the meeting and entitled to vote on the item. Abstentions will count as votes “against” the item. Broker non-vote shares are not entitled to vote on the item and, therefore, are not counted in the vote.

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 and “for” items 2 and 3.

How do I vote? If you are a stockholder of record, you may vote by:


•	calling the toll free telephone number on the enclosed proxy card


•	using the Internet as described on the enclosed proxy card or


•	returning the enclosed proxy card in the envelope provided.

If you are a beneficial owner, you must provide voting instructions to your bank, broker, or other nominee to ensure your shares are voted as you would like. You should follow their instructions.

You may also vote in person at the meeting. However, if you are the beneficial owner of the shares, you must obtain a legal proxy from your bank or broker and present it at the meeting. A legal proxy identifies you, states the number of shares you own, and gives you the right to vote those shares. Without a legal proxy we cannot identify you as the beneficial owner of the shares or know how many shares you have to vote.

Can I change my vote? Yes.

If you are a stockholder of record, you may revoke your proxy and change your vote by:


•	submitting a written revocation to the corporate secretary before the meeting


•	submitting a proxy bearing a later date to the corporate secretary before the meeting or


•	voting in person at the meeting.

If you are a beneficial owner, you may change your vote by providing later dated voting instructions to your bank, broker, or other nominee in accordance with their procedures or by obtaining a legal proxy and voting in person at the meeting, as set forth above.

He currently serves as executive director of the Robert B. Daugherty Foundation, Omaha, Nebraska, and formerly served on the advisory board of U.S. Bank NA Omaha.

Mr. Wilson is a certified public accountant, on inactive status. He received his bachelor’s degree in business administration, cum laude, from the University of Nebraska – Omaha. During his career, he was an audit manager at Peat, Marwick, Mitchell (now known as KPMG), controller for Great Plains Natural Gas Co., and chief financial officer and treasurer for all Durham Resources entities.

The board concluded that Mr. Wilson should serve as a director of MDU Resources Group, Inc., in light of our business and structure, at the time we file our proxy statement for the following reasons. Mr. Wilson has an extensive background in finance and accounting, as well as extensive experience with mergers and acquisitions, through his education and work experience at a major accounting firm and his later positions as controller and vice president of Great Plains Natural Gas Co., president of Great Plains Energy Corp., and president, chief financial officer, and treasurer for Durham Resources, LLC and all Durham Resources entities.

The board of directors recommends a vote “for” each nominee.

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.


•	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.

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

Although your ratification vote will not affect the appointment or retention of Deloitte & Touche LLP for 2015, 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 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
Deloitte & Touche LLP as our independent registered public accounting firm for 2015.

Pre-Approval Policy

The audit committee pre-approved all services Deloitte & Touche LLP performed in 2014 in accordance with the pre-approval policy and procedures the audit committee adopted at its August 12, 2003 meeting. 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 Securities and Exchange Commission.

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, Dennis W. Johnson, for approval. The designated member updates the audit committee at the next regularly scheduled meeting regarding any services that he 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.

ITEM 3. APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF 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 a separate 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, our compensation committee and board of directors believe that our current executive compensation program directly links compensation of our named executive officers to our financial performance and aligns the interests of our named executive officers with those of our stockholders. Our compensation committee and board of directors also believe that our executive compensation program provides our 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 our named executive officers on both an annual and long-term basis if they attain specified goals.

Our overall compensation program and philosophy is built on a foundation of these guiding principles:


•	we pay for performance, with over 50% of our 2014 total target direct compensation for our named executive officers in the form of incentive compensation


•	we assess the relationship between our named executive officers’ pay and performance on key financial metrics - revenue, profit, return on invested capital, and stockholder return - in comparison to our performance graph peer group


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


•	we determine annual performance incentives based on financial criteria that are important to stockholder value, including earnings, earnings per share, and return on invested capital and


•	we determine long-term performance incentives based on total stockholder return relative to our performance graph peer group.

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 2014. Accordingly, the following resolution is submitted for stockholder vote at the 2015 annual meeting:

12 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

“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, 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 our named executive officers remains with our compensation committee and our board of directors, although our board and compensation committee will consider the outcome of this vote when making future compensation decisions. As the board of directors determined at its meeting in May 2011, we will provide our stockholders with the opportunity to vote on our named executive officer compensation at every annual meeting until the next required vote on the frequency of stockholder votes on named executive officer compensation. The next required vote on frequency will occur at the 2017 annual meeting of stockholders.

The board of directors recommends a vote “for” the approval, on a non-binding advisory basis, of
the compensation of our named executive officers, as disclosed in this proxy statement.

Approval of the compensation of our named executive officers requires the affirmative vote of a majority of our 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 following Compensation Discussion and Analysis may contain statements regarding corporate performance targets and goals. These 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.

Key Financial Results for 2014

Consolidated GAAP earnings in 2014 were $297.5 million, or $1.55 per share, compared to earnings of $278.2 million, or $1.47 per share, in 2013.

Our total stockholder return for 2014 was (21.2%), as compared to 47.5% for 2013. Our average annual total stockholder return for the five-year period ended December 31, 2014 was 2.8%, compared to 10.5% for the five-year period ended December 31, 2013.

In 2014 the company generated a 7.0% return on invested capital compared to a 6.5% weighted average cost of capital.

Total Realized Pay Compared to Total Compensation from the Summary Compensation Table

The compensation committee believes considering total realized pay, the actual remuneration received by the named executive, is equally as important as considering total compensation as presented in the Summary Compensation Table. Total realized pay reflects the compensation actually earned, which can differ substantially from total compensation as presented in the Summary Compensation Table.

Total compensation as presented in the Summary Compensation Table contains estimated values of grants of performance shares based on multiple assumptions that may or may not come to fruition. In total realized pay, we do not include their value at grant but rather include their value upon vesting at the level they are actually earned. The Summary Compensation Table also shows any increase in pension value, which may result in large part from changes in the valuation assumptions and discount rates used for calculation. We exclude the increase in pension value and above-market earnings on nonqualified deferred compensation from total realized pay because:


•	the increase in pension value can have a large impact on total compensation as reported in the Summary Compensation Table


•	when pension value decreases, the negative value does not reduce total compensation as reported in the Summary Compensation Table


•	even though benefit accruals under our qualified defined benefit pension plan were discontinued effective December 31, 2009, the pension value for 2014 increased due partially to the company’s adoption of updated mortality tables and the use of a lower discount rate and


•	Supplemental Income Security Plan benefits depend partially on continued employment in the case of Messrs. Goodin and Schwartz.

We define total realized pay as the sum of:


•	base salary


•	annual incentive award paid with respect to the year


•	the value realized upon the vesting of long-term incentive awards of performance shares during the year and


•	all other compensation as reported in the Summary Compensation Table.

The following table compares total realized pay for our named executives in 2014 to the total compensation as presented in the Summary Compensation Table. This table is not intended to be a substitute for the Summary Compensation Table.



Named Executive Officer		Base Salary ($)	Annual Incentive Awards Paid ($)	Value Realized upon Vesting of Performance Shares ($)¹	All Other Compensation ($)	Total Realized Pay ($)	Total Compensation from the Summary Compensation Table ($)

Except for 2014, the yearly changes in our chief executive officers’ total realized pay align very closely with yearly changes in total stockholder return. The increase in total realized pay in 2014 is due predominantly to $1,047,202 that vested in 2014 related to the performance shares and dividend equivalents for the 2011 through 2013 performance cycle due to our stockholder performance relative to our performance graph peer group. Additionally, the yearly changes in our chief executive officers’ total compensation from the Summary Compensation Table correspond to the yearly changes in total stockholder return.

Process for Determination of 2014 Compensation

Objectives of our Compensation Program

We have a written executive compensation policy for our Section 16 officers, including all our named executive officers. Our policy’s stated objectives are to:


•	recruit, motivate, reward, and retain high performing executive talent required to create superior long-term total stockholder return in comparison to our peer group

MDU Resources Group, Inc. Proxy Statement 15

Proxy Statement


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


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


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


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

Role of Management

Our executive compensation policy calls for an assessment of the competitive pay levels for base salary and incentive compensation for each Section 16 officer position to be conducted at least every two years by an independent consulting firm. Towers Watson conducted the study in 2012 for use by the compensation committee to determine 2013 compensation levels. In 2013, the compensation committee requested the competitive assessment to be completed internally. They directed the vice president-human resources and the human resources department to prepare the competitive assessment in August 2013 on Section 16 officers for their use in establishing 2014 compensation.

The assessment included identifying any material changes to the positions analyzed, updating competitive compensation information, gathering and analyzing relevant general and industry-specific survey data, and updating the base salary structure. The human resources department assessed competitive pay levels for base salary, total annual cash, which is base salary plus target annual incentives, and total direct compensation, which is the sum of total annual cash and the expected value of long-term incentives. The competitive assessment compared our positions to like positions contained in general industry compensation surveys and industry specific compensation surveys. The human resources department aged the survey data from the date of the survey by 2.5% annually to estimate the 2014 competitive targets.

The compensation surveys used in the competitive assessment are listed on the following table:



Survey*		Number of Companies Participating (#)	Median Number of Employees (#) ¹	Number of Publicly Traded Companies (#)	Median Revenue (000s) ($)

¹	For the Effective Compensation, Inc. 2012 Oil and Gas Compensation Survey, the number reported as the Median Number of Employees is the average number of employees.

In billions of dollars, our revenues for 2012, 2013, and 2014 were approximately $4.1, $4.5, and $4.7, respectively.

The human resources department also augmented the competitive analysis by using Equilar to provide information on what was reported by companies in our performance graph peer group and by other public companies in relevant industries, as selected by the human resources department and as determined by SIC codes and as disclosed in their SEC filings. The companies referenced via Equilar and the positions for which they were used are found in Exhibit B.

For our president and chief executive officer, the Equilar companies included all companies in our performance graph peer group and data on 95 additional chief executive officers from public companies in the energy, construction, utility, and oil and gas exploration industries with revenues ranging from $1 billion to $8 billion.

For our vice president and chief financial officer, the Equilar companies included all companies in our performance graph peer group and data on 77 additional chief financial officers from public companies in the energy, construction, utility, and oil and gas exploration industries with revenues ranging from $1 billion to $8 billion.

16 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

For the chief executive officer of our exploration and production segment, the Equilar data consisted of compensation information on 25 chief operating officers from public companies in the oil and gas exploration and production industries with revenues ranging from $250 million to $1.5 billion, and 33 division heads from public companies in the oil and gas exploration and production industries without regard to revenues.

For the president and chief executive officer of our construction services segment, the Equilar data consisted of compensation information on four chief operating officers and four division heads from public companies in the construction services industry, without regard to revenues.

For the president and chief executive officer of our pipeline and energy services segment, the Equilar data consisted of compensation information on seven chief operating officers from public companies in the energy services industry with revenues ranging up to $1.25 billion and, separately, 27 division heads from public companies in the energy services industry without regard to revenues.

The chief executive officer played an important role in recommending 2014 compensation to the committee for the other named executive officers. The chief executive officer assessed the performance of the named executive officers and considered the relative value of the named executive officers’ positions and their salary grade classifications. He then reviewed the competitive assessment prepared by the human resources department to formulate 2014 compensation recommendations for the compensation committee, other than for himself. The chief executive officer attended compensation committee meetings; however, he was not present during discussions regarding his compensation.

Performance Assessment Program

Our performance assessment program rates performance of our executive officers, except for our chief executive officer, in the following areas, which help determine actual salaries within the range of salaries associated with the executive’s salary grade:



•	leadership	•	mentoring
•	leading with integrity	•	financial responsibility
•	achievement focus	•	safety
•	risk management

An executive’s overall performance in our performance assessment program is rated on a scale of one to five, with five as the highest rating denoting distinguished performance. An overall performance above 3.75 is considered commendable performance.

Salary Grades for 2014

The compensation committee determines the named executive officers’ base salaries and target annual and long-term incentives by reference to salary grades. Each salary grade has a minimum, midpoint, and maximum annual salary level with the midpoint targeted at approximately the 50th percentile of the competitive assessment data for positions in the salary grade. The compensation committee may adjust the salary grades away from the 50th percentile in order to balance the external market data with internal equity. The salary grades also have target annual and long-term incentive levels, which are expressed as a percentage of the individual’s actual base salary. We generally place named executive officers into a salary grade based on historical classification of their positions; however, the compensation committee reviews each classification and may place a position into a different salary grade if it determines that the targeted competitive compensation for the position changes significantly or the executive’s responsibilities and/or performance warrants a different salary grade. Individual executives may be paid below, equal to, or above the salary grade midpoint.

The salary grades give the compensation committee flexibility to assign different salaries to individual executives within a salary grade to reflect one or more of the following:


•	executive’s performance on financial goals and on non-financial goals, including the results of the performance assessment program


•	executive’s experience, tenure, and future potential


•	position’s relative value compared to other positions within the company


•	relationship of the salary to the competitive salary market value


•	internal equity with other executives and


•	economic environment of the corporation or executive’s business segment.

MDU Resources Group, Inc. Proxy Statement 17

Proxy Statement

The committee did not change the named executives’ salary grades, but increased the base salary midpoints for 2014 for salary grades A through L by an average of 1.52% to more closely align with the 50th percentile of the competitive assessment data. The midpoint of salary grade L, which is Mr. Goodin’s salary grade, was increased by 2.3% from $762.5 thousand to $780 thousand; the midpoint of salary grade K, which is Mr. Wells’ salary grade, was increased by 3.0% from $500 thousand to $515 thousand; the midpoint of salary grade J, which is Messrs. Thiede and Bietz’s salary grade, remained at $390 thousand; and the midpoint of salary grade I, which is Mr. Schwartz’s salary grade, was increased by 1.5% from $335 thousand to $340 thousand.

The committee did not change the target incentive compensation guidelines for the salary grades for 2014, except that 2014 target annual and long-term incentives were set at 85% and 60% of base salary, respectively, for the salary grade J president and chief executive officer of the construction services segment (Mr. Thiede) and president and chief executive officer of the construction materials segment, rather than the target annual and long-term incentive guidelines associated with salary grade J of 65% and 90%, respectively, of base salary. In establishing these targets, the committee continued its approach on transitioning these two executive officers’ incentive compensation from what it had been prior to their promotions in 2013 to having their targets equal to those of other salary grade J participants by 2017.

Our named executive officers’ 2014 salary grade classifications and their respective midpoints are:



				2014 Salary Grade Base Salary Midpoint ($000s)
Position		Grade	Name	2014 Salary Grade Base Salary Midpoint ($000s)
President and CEO	L		David L. Goodin		780

President and CEO, WBI Holdings, Inc.	J		Steven L. Bietz		390

Timing of Compensation Decisions for 2014

The compensation committee, in conjunction with the board of directors, determined all compensation for each named executive officer for 2014. The compensation committee made recommendations to the board of directors regarding compensation of all Section 16 officers, and the board of directors then approved the recommendations.

The compensation committee reviewed the competitive assessment at its August 2013 and November 2013 meetings. At the November 2013 meeting, it established individual base salaries, target annual incentive award levels, and target long-term incentive award levels for 2014. At the February 2014 meeting, the compensation committee and the board of directors determined 2014 annual and long-term incentive awards, along with payments based on performance for the 2013 annual incentive awards and the 2011-2013 performance share awards. The February meeting occurred after the release of earnings for the prior year.

Stockholder Advisory Vote (“Say on Pay”)

Our stockholders had an advisory vote on our named executive officers’ compensation at the 2014 Annual Meeting of Stockholders. Approximately 97% of the shares present in person or represented by proxy and entitled to vote on the matter approved the named executive officers’ compensation. The 97% approval is slightly higher than the results of our say on pay vote at the 2013 Annual Meeting, which was 96%. The compensation committee and the board of directors considered the results of the votes at their May 2014 and November 2014 meetings and did not change our executive compensation program as a result of the votes.

Allocation of Total Target Compensation for 2014

Incentive compensation, which consists of annual cash incentive awards and three-year performance share awards under our Long-Term Performance-Based Incentive Plan, comprises a significant portion of our named executive officers’ total target compensation because:


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


•	incentive compensation is more variable than base salary and dependent upon our performance


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


•	the interests of our named executive officers will be aligned with those of our stockholders by making a significant portion of their target compensation contingent upon results that are beneficial to stockholders.

18 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

The following table shows the allocation of total target compensation for 2014 among the individual components of base salary, annual incentive, and long-term incentive:



Name	% of Total Target Compensation Allocated to Base Salary (%)	% of Total Target Compensation Allocated to Incentives
Name	% of Total Target Compensation Allocated to Base Salary (%)	Annual (%)	Long-Term (%)	Annual + Long-Term (%)
David L. Goodin	25.0	37.5	37.5	75.0
Doran N. Schwartz	44.4	22.2	33.4	55.6
J. Kent Wells	23.5	29.4	47.1	76.5
Jeffrey S. Thiede	40.8	34.7	24.5	59.2
Steven L. Bietz	39.2	25.5	35.3	60.8

In order to reward long-term growth, the compensation committee generally allocates a higher percentage of total target compensation to the long-term incentive than to the short-term incentive for our higher level executives, since they are in a better position to influence our long-term performance. As discussed later, Mr. Goodin’s long-term incentive percentage was kept at a lower level to balance his higher Supplemental Income Security Plan benefit. Also, Mr. Thiede’s long-term incentive percentage was lower than the guideline, as he transitions from all short-term incentive to a combination of short-term and long-term incentive in connection with his promotion in 2013. Additionally, the long-term incentive, if earned, is paid in company common stock. These awards, combined with our stock retention requirements and stock ownership policy, discussed later, promote ownership of our stock by the named executive officers. The compensation committee believes that, as stockholders, the named executive officers will be motivated to deliver financial results that build wealth for all stockholders over the long-term.

PEER Analysis: Comparison of Pay for Performance Ratios

Each year we compare our named executive officers’ pay for performance ratios to the pay for performance ratios of the named executive officers in the performance graph peer group. This analysis compares the relationship between our compensation levels and our average annual total stockholder return to the peer group over a five-year period. All data used in the analysis, including the valuation of long-term incentives and calculation of stockholder return, were compiled by Equilar, Inc., an independent service provider, which is based on each company’s annual filings for its data collection.

This analysis consisted of dividing what we paid our named executive officers for the years 2009 through 2013 by our average annual total stockholder return for the same five-year period to yield our pay ratio. For the 2009-2013 comparison, we used the 2014 performance graph peer group companies. Our pay ratio was then compared to the pay ratio of the companies in the performance graph peer group, which was calculated by dividing total direct compensation for all the proxy group executives by the sum of each company’s average annual total stockholder return for the same five-year period. The average annual stockholder return is the geometric mean for the five-year period.

For the five-year period of 2009 through 2013, we paid our named executives approximately $4.9 million per point of shareholder return, while the peer group companies paid their named executives approximately $6.4 million per point of shareholder return. The compensation committee believes that the analysis continues to serve a useful purpose in its annual review of compensation for the named executives.

2014 Compensation for Our Named Executive Officers

Base Salaries, Total Annual Compensation, and Total Direct Compensation

David L. Goodin

For 2014, the compensation committee awarded Mr. Goodin, our president and chief executive officer, a 9.6% increase, raising his salary from $625,000 to $685,000, or 87.8% of the midpoint of salary grade L. The committee noted that the $685,000 was below the median salary of $750,000 for the chief executive officers from the performance graph peer companies and below the median salary of $801,500 for the chief executive officers from the salary survey data, both as noted in the competitive assessment. The committee believed the 9.6% increase was appropriate in light of Mr. Goodin’s job maturity, knowledge of the company’s business segments, skill sets, and management style, in addition to 2013 performance, which included earnings per share and return on invested capital results at 103.9% of plan and 103.1% of plan, respectively, as measured on a nine month actual plus three month plan basis. The committee also believed it was appropriate for Mr. Goodin’s 2014 base salary to be less than market and less than the 2014 midpoint due to his newness in the position. The committee established Mr. Goodin’s 2014 target total annual cash compensation at $1,712,500, which was above the median total cash compensation of $1,664,600 paid to chief executive officers from the performance graph peer companies and above the median total cash compensation of $1,532,700 paid to chief executive officers from the salary survey data, both as noted in the competitive assessment.

MDU Resources Group, Inc. Proxy Statement 19

Proxy Statement

From a total direct compensation perspective, the committee established a target of $2,740,000, which was above the competitive reference point of $2,565,600 for the performance graph peer group and below the competitive reference point of $3,192,800 for the salary survey companies.

Doran N. Schwartz

For 2014, the compensation committee awarded Mr. Schwartz, our vice president and chief financial officer, a 4.3% increase, raising his salary from $345,000 to $360,000, or to 105.9% of the midpoint of salary grade I. Combined with his target annual and long-term incentive, this would result in target total annual compensation of 73% and target total direct compensation of 54% of the 2014 competitive salary survey data at the 50th percentile. The compensation committee’s rationale for the increase was in recognition of his:


•	assistance in the company delivering earnings per share and return on invested capital results at 103.9% of plan and 103.1% of plan, respectively, as measured on a nine month actual plus three month plan basis


•	leadership in maintaining excellent relationships with the investment community and


•	relatively low salary compared to the chief financial officers of performance graph peer companies.

J. Kent Wells

For 2014, the compensation committee awarded Mr. Wells, vice chairman of the corporation and chief executive officer of Fidelity Exploration & Production Company, a 5.3% increase, raising his salary from $570,000 to $600,000 or 116.5% of the midpoint of salary grade K. Combined with his target annual and long-term incentives, this would result in target total annual compensation of 123% and target total direct compensation of 136% of the 2014 competitive salary survey data at the 50th percentile. The compensation committee’s rationale for the increase was in recognition of:


•	Fidelity Exploration & Production’s continued growth in production and continuing the shift in production mix from natural gas to oil and liquids and


•	continuing to promote a safety culture at Fidelity Exploration & Production Company.

Jeffrey S. Thiede

For 2014, the compensation committee awarded Mr. Thiede, president and chief executive officer of MDU Construction Services Group, Inc., a 3.9% increase, raising his annual salary from $385,000 to $400,000, or 102.6% of the midpoint of salary grade J. Due to the limited salary survey data on comparable positions, the 2014 competitive assessment was based solely on the Equilar data discussed above under “Role of Management.” Combined with his target annual and long-term incentives, Mr. Thiede’s target total annual compensation and target total direct compensation was 81% and 87%, respectively, of the median proxy pay data on chief operating officers, and 93% and 123%, respectively, of the median proxy pay data on division heads. The committee believed the 3.9% salary increase was appropriate in light of his grasp of financial targets and budget goals and 2013 performance, which included earnings per share and return on invested capital results at 130.1% of plan and 121.9% of plan, respectively, as measured on a nine-month actual plus three-month plan basis for MDU Construction Services Group, Inc.

Steven L. Bietz

For 2014, the compensation committee awarded Mr. Bietz, president and chief executive officer of WBI Holdings, Inc., a 3.3% increase, raising his salary from $367,700 to $380,000, or 97.4% of the midpoint of salary grade J. Combined with his target annual and long-term incentives, this would result in target total annual compensation of 94% and target total direct compensation of 89% of the 2014 competitive salary survey data at the 50th percentile. The compensation committee’s rationale for the increase was in recognition of his leadership in WBI Holdings, Inc.’s expansion in the gas processing and refining areas.

Annual Incentives

What the Performance Measures Are and Why We Chose Them

The compensation committee develops and reviews financial and other corporate performance measures to help ensure that compensation to the executives reflects the success of their respective business segment and/or the corporation, as well as the value provided to our stockholders.

The compensation committee believes earnings, earnings per share, and return on invested capital are very good measurements in assessing a business segment’s performance and the company’s performance from a financial perspective, because:

20 MDU Resources Group, Inc. Proxy Statement

Proxy Statement


•	earnings and earnings per share are generally accepted accounting principle measurements and are key drivers of stockholder return over the long-term and


•	return on invested capital measures how efficiently and effectively management deploys capital, where sustained returns on invested capital in excess of a business segment’s cost of capital create value for our stockholders.

The compensation committee chose earnings as the performance measure for two business segments. For the construction services segment, selected earnings levels were used in order to balance the difficulty in forecasting as well as earnings volatility for that segment, instead of tying performance to allocated earnings per share and budgeted return on invested capital resulting from the annual planning process. For the exploration and production segment, earnings, as adjusted, were used to motivate the chief executive officer to increase and maintain production at a high level and develop the appropriate mix of production and replacement reserves, without regard to the effect on earnings of non-cash impairments and hedge accounting, the pricing components over which he had no control.

As in prior years, the compensation committee selected allocated earnings per share and return on invested capital for the pipeline and energy services segment, the electric and natural gas distribution segments, and the construction materials and contracting segment to ensure those chief executive officers’ annual incentive payments are closely aligned to criteria promoting long-term growth in stockholder return. We establish these targets in connection with our annual financial planning process, where we assess the economic environment, competitive outlook, industry trends, and company specific conditions to set projections of results. The compensation committee evaluates the projected results and uses this evaluation to establish the incentive plan performance targets based upon recommendation of the chief executive officer. Allocated earnings per share for a business segment is calculated by dividing that business segment’s earnings by the business segment’s portion of the total company weighted average shares outstanding. Return on invested capital for a business segment is calculated by dividing the business segment’s earnings, without regard to after tax interest expense and preferred stock dividends, by the business segment’s average capitalization for the calendar year. If the compensation committee utilizes a return on invested capital target for a business segment, it considers the business segment’s weighted average cost of capital. The weighted average cost of capital is a composite cost of the individual sources of funds including equity and debt used to finance a company’s assets. It is calculated by averaging the cost of debt plus the cost of equity by the proportion each represents in our, or the business segment’s, capital structure.

For the named executive officers working at MDU Resources Group, Inc., who were Messrs. Goodin and Schwartz, the compensation committee continued to base annual incentives on the achievement of performance goals at the business segments: (i) the construction materials and contracting segment, (ii) the construction services segment, (iii) the pipeline and energy services segment, (iv) the exploration and production segment, and (v) the electric and natural gas distribution segments. The compensation committee’s rationale for this approach was to provide greater alignment between the MDU Resources Group, Inc. executives and business segment performance.

As established by the compensation committee in February 2014, the annual performance measures and goal weightings for the business segment leaders were:



Position		Business Segment	Business Segment Goal Weighting				Company Goal Weighting
Position		Business Segment	Allocated EPS (%)	ROIC (%)	Earnings (%)		EPS (%)¹
President and Chief Executive Officer		Exploration and Production	—	—	75.0	²	25.0
President and Chief Executive Officer		Construction Services	—	—	75.0	³	25.0
President and Chief Executive Officer		Pipeline and Energy Services	37.5	37.5	—		25.0
President and Chief Executive Officer		Construction Materials and Contracting	37.5	37.5	—		25.0
President and Chief Executive Officer		Electric and Natural Gas Distribution	37.5	37.5	—		25.0
¹	Earnings per share for purposes of the annual incentive calculation (i) reflect the adjustments referred to in footnote 2 and (ii) exclude the effects on earnings at the MDU Resources level of intersegment eliminations.
²	Earnings were defined as GAAP earnings reported for the exploration and production segment, adjusted to exclude the (i) effect on earnings of any noncash write-downs of oil and natural gas properties due to ceiling test impairment charges and any associated earnings benefit resulting from lower depletion, depreciation and amortization expenses and (ii) the effect on earnings of any noncash gains and losses that result from (x) ineffectiveness in hedge accounting or (y) derivatives that no longer qualify for hedge accounting treatment.
³	Earnings were defined as GAAP earnings.

Our Named Executive Officers’ Target Annual Incentive Compensation

The compensation committee established the named executive officers’ target annual incentive as a percentage of each officer’s actual 2014 base salary.

Messrs. Goodin’s and Schwartz’s 2014 target annual incentives were based on the following:

•

Mr. Goodin’s 2014 target annual incentive was unchanged at 150% of base salary, which was above the 91% and 122% of base salary paid to chief executive officer positions based on salary survey data and performance graph peer group data, respectively, from the competitive assessment. The committee’s rationale for assigning an above-market target annual incentive percentage was to offset a below-market target long-term incentive and to ensure, from an internal equity standpoint, that Mr. Goodin’s target incentive was above the target incentives of his direct reports.

•

Mr. Schwartz’s 2014 target annual incentive was unchanged at 50% of base salary, which was below the 67% and 77% of base salary paid to chief financial officers based on salary survey data and performance graph peer group data, respectively, from the competitive assessment. Notwithstanding this difference, the committee did not increase Mr. Schwartz’s annual incentive target in favor of waiting some additional time before increasing the annual incentive target.

Mr. Wells’ 2014 target incentive was unchanged at 125% of base salary, which was above the 96% of base salary paid to comparable positions in the survey data and above the 82% and 80% of base salary based on proxy pay data from SEC filings as of July 2013, and as compiled by Equilar, on chief operating officers and division heads from companies in relevant industries. The compensation committee determined, as it had in prior years, that the target incentive of 125% of base salary was appropriate given the significant investment in the exploration and production segment and the desire to incentivize and motivate Mr. Wells to generate earnings that can greatly impact overall company earnings.

Mr. Thiede’s 2014 target incentive was set at 85% of base salary, a decrease from 90% of base salary in 2013. The decrease was part of the committee’s plan to decrease his short-term target incentive to 65% of base salary by 2017 while, at the same time, increasing his long-term incentive target to 90% of base salary over the same time period.

Mr. Bietz’s 2014 target incentive was unchanged from 2013 and set at 65% of base salary, which was below the 74% of base salary paid to comparable positions in the survey data. Notwithstanding the difference, the committee did not increase Mr. Bietz’s incentive target for 2014 because the historical trend has shown smaller differences between the incentive target awarded to Mr. Bietz and the competitive data, and the committee determined not to change the target based on a one-year result.

MDU Resources Group, Inc. EPS Goal

The MDU Resources Group, Inc. earnings per share component represented 25% of the award opportunity for all business segment leaders. Payout could range from no payment if the results were below 85% of the $1.48 target to a 200% payout if the results were $1.70 or higher. The committee set the target at $1.48, as adjusted, which was above the 2013 target of $1.27 and below the adjusted 2013 results of $1.49. The 2014 target was established based on adjusted earnings at the exploration and production segment as described in footnote 2 to the table under What the Performance Measures Are and Why We Chose Them above and excluded the effect on earnings at the company level of intersegment eliminations. The 2014 adjusted earnings per share target level reflected:


•	continued solid execution in all business segments


•	significant investments in our exploration and production, electric and natural gas distribution, and pipeline and energy services segments and


•	anticipated lower oil and natural gas commodity prices.

Earnings per share for 2014 were, on a GAAP basis, $1.55 and, on an adjusted basis as described in footnotes 1 and 2 to the table above under What the Performance Measures Are and Why We Chose them, were $1.50. The payment on this component was 109% of target.

Exploration and Production Segment Earnings Goal

For Mr. Wells, 75% of the 2014 award opportunity was based on earnings adjusted as described in footnote 2 to the table above under What the Performance Measures Are and Why We Chose Them. Payout could range from no payment if 2014 earnings were below the 85% level of $81.2 million to a 200% payout if the segment’s 2014 earnings were at or above the 115% level of $109.8 million. For 2014 the 85% to 115% range was wider than the 90% to 110% range for 2013 to accommodate an expected increase in commodity price volatility for 2014.

22 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

The committee set the exploration and production segment’s 2014 adjusted earnings target level at $95.5 million, which was above the 2013 target level of $84.0 million and below the 2013 adjusted results of $98.4 million. The 2014 earnings target as compared to 2013 adjusted results and target was due primarily to higher depletion, depreciation and amortization expense, and lower expected commodity prices, as well as expected increased oil production.

The segment’s 2014 earnings were $82.0 million equating to a 29.3% payment on the segment’s earnings component, which coupled with MDU Resources Group, Inc.’s earnings per share being 109% of target, resulted in a 2014 annual incentive payment for Mr. Wells of $369,750 or 49.3% of target.

Construction Services Segment Earnings Goal

For Mr. Thiede, 75% of the 2014 incentive award opportunity was based on the construction services segment’s 2014 earnings, where the payout could range from no payment if the results were below the 70% level of $14.5 million to 250% of the target amount if the results were at or above $35.8 million.

Predetermined earnings levels were selected in order to balance the difficulty in forecasting as well as earnings volatility for that segment. Specifically, earnings of $20.9 million, the result necessary to trigger payment of the target award, equated to a return on invested capital of approximately 7.2%, and earnings of $35.8 million, the result necessary to trigger payment of the maximum award, equated to a return on invested capital of approximately 12.2%. The committee felt these earnings levels were appropriate given the business segment’s 2014 projected weighted average cost of capital was 9%.

The construction services segment’s 2014 earnings were $54.4 million, equating to a 250% payment on the segment’s earnings component, which coupled with MDU Resources Group, Inc.’s earnings per share being 109% of target, resulted in a 2014 annual incentive payment for Mr. Thiede of $730,150 or 214.8% of target.

Pipeline and Energy Services Segment EPS, ROIC, and Safety Goals

For Mr. Bietz, 75% of the 2014 award opportunity was based on the pipeline and energy service segment’s allocated earnings per share and budgeted return on invested capital, equally weighted. Payout could range from no payment if the results were below the 85% level of $0.83 EPS and 3.3% ROIC to a 200% payout if:


•	the 2014 allocated earnings per share for the segment were at or above the 115% level of $1.13 and


•	the 2014 return on invested capital was at or above the 115% level of 4.5%.

For 2014, the committee set the pipeline and energy service segment’s allocated earnings per share target at $0.98 and return on invested capital target at 3.9%. The 2014 earnings per share target was below the 2013 target of $1.16, reflecting lower anticipated natural gas storage levels and start-up costs associated with Dakota Prairie Refining, LLC. The 2014 earnings per share target was also above the 2013 earnings per share results of $0.51 due to anticipated improved results from the business segment’s Pronghorn facility, anticipated higher transportation volumes, and the absence of the $9.0 million negative earnings impact associated with the impairment of natural gas gathering assets that occurred in 2013. The 2014 ROIC target of 3.9% was below the 2013 target of 5.4% and above the 2013 actual results of 3.1%, due primarily to the capital investments in Dakota Prairie Refining.

Mr. Bietz also had five individual goals relating to safety results with each goal that was not met reducing the annual incentive award by 1%. The five individual goals were:


•	each established local safety committee will conduct eight meetings per year


•	each established local safety committee must conduct four site assessments per year


•	report motor vehicle accidents and personal injuries by the end of the next business day, which will be achieved only if 85% or more of the reports are submitted by the end of the next business day


•	achieve the targeted vehicle accident incident rate of 1.85 or less and


•	achieve the targeted personal injury incident rate of 2.1 or less.

MDU Resources Group, Inc. Proxy Statement 23

Proxy Statement

Results at the pipeline and energy services segment (before adjustment for the five safety goals) were 138.8% and 130.8%, respectively, of the 2014 allocated earnings per share and return on invested capital measures, equating to 200% of target each. These results, coupled with MDU Resources Group, Inc.’s earnings per share being 109% of target and four of the five safety goals being met, resulted in 175.5% of the target being met, or an award of $433,552. However, the committee used its negative discretion and reduced Mr. Bietz’s award to $333,552 due to the cost overruns and delay in the start date at Dakota Prairie Refining.

Electric and Natural Gas Distribution Segments EPS and ROIC Goals

For the electric and natural gas distribution segments, 75% of the 2014 award opportunity was based on allocated earnings per share and budgeted return on invested capital, equally weighted. Payout could range from no payment if the allocated earnings per share and return on invested capital results were below the 85% level of $1.11 EPS and 4.8% ROIC to a 200% payout if:


•	the 2014 allocated earnings per share for the segment were at or above the 115% level of $1.50 and


•	the 2014 return on invested capital was at or above the 115% level of 6.6%.

The committee set the 2014 target for allocated earnings per share at $1.30, which was higher than the 2013 target and equal to the 2013 actual results to reflect anticipated increased operating efficiencies, offset by higher investments. The committee set the 2014 return on invested capital target at 5.7%, which was lower than the 2013 target level and the 2013 actual results to reflect higher invested capital associated with its growth projects. The 2014 return on invested capital target was above the segment’s projected 2014 weighted average cost of capital.

For 2014, the electric and natural gas distribution segments’ earnings per share and return on invested capital were 89.2% and 93.0% of their respective targets, equating to 46.2% and 64.9%, respectively, of the target amount attributable to those components, which coupled with MDU Resources Group, Inc.’s earnings per share being 109% of target, led to overall results for these segments of 68.9% of the 2014 target annual incentive award.

Construction Materials and Contracting Segment EPS and ROIC Goals

For the construction materials and contracting segment, 75% of the 2014 award opportunity was based on allocated earnings per share and budgeted return on invested capital, equally weighted. Payout could range from no payment if the results were below the 70% level of $0.58 EPS and 4.4% ROIC to a 200% payout if:


•	the 2014 allocated earnings per share for the segment were at or above the 115% level of $0.95 and


•	the 2014 return on invested capital was at or above the 138% level of 8.7%.

For the construction materials and contracting segment, the committee set the 2014 allocated earnings per share target at $0.83, which was higher than the 2013 target of $0.52 and actual results of $0.77, to reflect anticipated increases in construction materials volumes and construction activity in western North Dakota and Texas. The committee set the 2014 return on invested capital target at 6.3%, higher than the 2013 target of 4.3% and the 2013 actual results of 6.1%, due to higher anticipated earnings.

The construction materials and contracting segment’s 2014 earnings per share and return on invested capital were 95.2% and 98.4% of their respective 2014 targets, equating to 88.0% and 96.0%, respectively, of the target amount attributable to those components, which coupled with MDU Resources Group, Inc.’s earnings per share being 109% of target, led to overall results for this segment of 96.3% of the 2014 target annual incentive award.

Deferral of Annual Incentive Compensation

We provide executives the opportunity to defer receipt of earned annual incentives. If an executive chooses to defer his or her annual incentive, we will credit the deferral with interest at a rate determined by the compensation committee. For 2014, the committee chose to use the average of (i) the number that results from adding the daily Moody’s U.S. Long-Term Corporate Bond Yield Average for “A” rated companies as of the last day of each month for the 12-month period ending October 31 and dividing by 12, and (ii) the number that results from adding the daily Moody’s U.S. Long-Term Corporate Bond Yield Average for “Baa” rated companies as of the last day of each month for the 12-month period ending October 31 and dividing by 12. This resulted in an interest rate of 4.67%. The compensation committee’s reasons for using this approach recognized:


•	incentive deferrals are a low-cost source of capital for the company and


•	incentive deferrals are unsecured obligations and, therefore, carry a higher risk to the executives.

2014 Long-Term Incentives

Performance Share Awards

We use the Long-Term Performance-Based Incentive Plan, which has been approved by our stockholders, for long-term incentive compensation, with performance shares as the primary form of long-term incentive compensation. We have not granted stock options since 2001, and in 2011 we amended the plan to no longer permit the grant of stock options or stock appreciation rights; no stock options, stock appreciation rights, or restricted shares are outstanding.

The compensation committee has used relative stockholder return in comparison to the performance graph peer group as the performance measure for a number of years, including the 2014 performance share awards. The performance graph peer group consisted of the following companies when the committee granted performance shares in February 2014.



•	ALLETE, Inc.	•	EQT Corporation	•	SM Energy Company
•	Alliant Energy Corporation	•	Granite Construction Incorporated	•	Sterling Construction Company, Inc.
•	Atmos Energy Corporation	•	Martin Marietta Materials, Inc.	•	Swift Energy Company
•	Avista Corporation	•	National Fuel Gas Company	•	Texas Industries
•	Bill Barrett Corporation	•	Northwest Natural Gas Company	•	Vectren Corporation
•	Black Hills Corporation	•	Pike Corporation	•	Vulcan Materials Company
•	Comstock Resources, Inc.	•	Quanta Services, Inc.	•	Whiting Petroleum Corporation
•	EMCOR Group, Inc.	•	Questar Corporation

The performance measure is our total stockholder return over a three-year measurement period as compared to the total stockholder returns of the companies in our performance graph peer group over the same three-year period. The compensation committee selected the relative stockholder return performance measure because it believes executive pay under a long-term, capital accumulation program such as this should mirror our long-term performance in stockholder return as compared to other public companies in our industries. Payments are made in company stock; dividend equivalents are paid in cash. No dividend equivalents are paid on unvested performance shares.

26 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

Total stockholder return is the percentage change in the value of an investment in the common stock of a company, from the closing price on the last trading day in the calendar year preceding the beginning of the performance period, through the last trading day in the final year of the performance period. It is assumed that dividends are reinvested in additional shares of common stock at the frequency paid.

As with the target annual incentive, we determined the target long-term incentive for a given position in part from the competitive assessment and in part by the compensation committee’s judgment on the impact each position has on our total stockholder return. The committee kept the chief executive officer’s target long-term incentive below a level indicated from the competitive assessment. Mr. Goodin’s target was 150% of base salary, below the salary survey median of 207% of base salary and above the performance graph peer group median of 120% of base salary for chief executive officers. The compensation committee has historically set the president and chief executive officer’s target long-term incentive compensation below the level indicated by the salary survey data in the competitive assessment to offset his benefit under the Supplemental Income Security Plan, our nonqualified defined benefit plan, which prior assessments had shown to be higher than competitive levels.

Messrs. Schwartz’s and Wells’ target long-term incentives were unchanged from 2013. Mr. Schwartz’s target long-term incentive of 75% of base salary was below the salary survey median of 175% of base salary and below the performance graph peer group median of 79% of base salary for chief financial officers. Mr. Wells’ target long-term incentive was 200% of base salary, which was above the salary survey median of 138% and above the proxy pay data from SEC filings as of July, 2013, and as compiled by Equilar, of 146% of base salary on chief operating officers and 68% of base salary on division heads from companies in relevant industries. We believed that Mr. Wells’ long-term incentive target was appropriate due to his lack of participation in our supplemental income security plan and our nonqualified defined contribution plan.

Mr. Thiede’s long-term incentive target was set at 60% of base salary for 2014, his first year of participation in the long-term incentive plan. The establishment of his long-term incentive target at 60% of salary was part of the committee’s plan to increase his long-term target incentive to 90% of base salary by 2017 while, at the same time, decreasing his short-term incentive target to 65% of base salary over the same period. Mr. Bietz’s 2014 target long-term incentive was 90% of base salary and was unchanged from 2013. The 90% of target was below the salary survey median of 110% of base salary and above the proxy pay data from SEC filings as of July 2013, and as compiled by Equilar, of 71% of base salary on chief operating officers and 59% of base salary on division heads from companies in relevant industries.

On February 13, 2014, the board of directors, upon recommendation of the compensation committee, made performance share grants to the named executive officers. The compensation committee determined the target number of performance shares granted to each named executive officer by multiplying the named executive officer’s 2014 base salary by his target long-term incentive and then dividing this product by the average of the closing prices of our stock from January 1, 2014 through January 22, 2014, as shown in the following table:



Name	2014 Base Salary to Determine Target ($)	2014 Target Long-Term Incentive at Time of Grant (%)	2014 Target Long-Term Incentive at Time of Grant ($)	Average Closing Price of Our Stock From January 1 Through January 22 ($)	Resulting Number of Performance Shares Granted on February 13 (#)
David L. Goodin	685,000	150	1,027,500	30.51	33,677
Doran N. Schwartz	360,000	75	270,000	30.51	8,849
J. Kent Wells	600,000	200	1,200,000	30.51	39,331
Jeffrey S. Thiede	400,000	60	240,000	30.51	7,866
Steven L. Bietz	380,000	90	342,000	30.51	11,209

Assuming our three-year (2014 through 2016) total stockholder return is positive, from 0% to 200% of the target grant will be paid out in February 2017 depending on our total stockholder return compared to the total three-year stockholder returns of companies in our performance graph peer group. The payout percentage will be a function of our rank against our performance graph peer group as delineated in the following table:

Long-Term Incentive Payout Percentages



The Company’s Percentile Rank	Payout Percentage of February 13, 2014 Grant
75th or higher	200%
50th	100%
25th	20%
Less than 25th	0%

MDU Resources Group, Inc. Proxy Statement 27

Proxy Statement

Payouts for percentile ranks falling between the intervals will be interpolated. We also will pay dividend equivalents in cash on the number of shares actually earned for the performance period. The dividend equivalents will be paid in 2017 at the same time as the performance share awards are paid.

As had been established for awards granted beginning in 2011, if our total stockholder return is negative, the shares and dividend equivalents otherwise earned, if any, will be reduced in accordance with the following table:



Total Stockholder Return	Reduction in Award
0% through -5%	50%
-5.01% through -10%	60%
-10.01% through -15%	70%
-15.01% through -20%	80%
-20.01% through -25%	90%
-25.01% or below	100%

The named executive officers must retain 50% of the net after-tax shares that are earned pursuant to this long-term incentive award until the earlier of (i) the end of the two-year period commencing on the date any shares earned under the award are issued and (ii) the executive’s termination of employment.

Payment in February 2014 for 2011 Grants under the Long-Term Performance-Based Incentive Plan

We granted performance shares to our named executive officers under the Long-Term Performance-Based Incentive Plan on February 17, 2011 for the 2011 through 2013 performance period. Our total stockholder return for the 2011 through 2013 performance period was 64.37%, which corresponded to a percentile rank of 87% against our performance graph peer group and resulted in 193% of the shares granted in 2011, plus dividend equivalents, being paid to the named executive officers except for Messrs. Wells and Thiede, who did not participate in the program in 2011.

Clawback

In November 2005, we implemented a guideline for repayment of incentives due to accounting restatements, commonly referred to as a clawback policy, whereby the compensation committee may seek repayment of annual and long-term incentives paid to executives if accounting restatements occur within three years after the payment of incentives under the annual and long-term plans. Under our clawback policy, the compensation committee may require executives to forfeit awards and may rescind vesting, or the acceleration of vesting, of an award.

Post-Termination Compensation and Benefits

Pension Plans

Effective in 2006, we no longer offer defined benefit pension plans to new non-bargaining unit employees. The defined benefit plans available to employees hired before 2006 were amended to cease benefit accruals as of December 31, 2009. The frozen benefit provided through our qualified defined benefit pension plans is determined by years of service and base salary. Effective 2010, for those employees who were participants in defined benefit pension plans and for executives and other non-bargaining unit employees hired after 2006, the company offers increased company contributions to our 401(k) plan. For non-bargaining unit employees hired after 2006, the retirement contribution is 5% of plan eligible compensation. For participants hired prior to 2006, retirement contributions are based on the participant’s age as of December 31, 2009. The retirement contribution is 11.5% for Messrs. Goodin and Bietz, 10.5% for Mr. Schwartz, and 5% for Mr. Wells and Mr. Thiede, which amounts may be reduced in accordance with the provisions of the 401(k) plan.

Supplemental Income Security Plan

Benefits Offered

We offer certain key managers and executives, including all of our named executive officers, except Mr. Wells and Mr. Thiede, benefits under our nonqualified retirement plan, which we refer to as the Supplemental Income Security Plan or SISP. The SISP has a ten-year vesting schedule and was amended to add an additional vesting requirement for benefit level increases occurring on or after January 1, 2010. The SISP provides participants with additional retirement income and death benefits.

We believe the SISP is effective in retaining the talent necessary to drive long-term stockholder value. In addition, we believe that the ten-year vesting provision of the SISP, augmented by an additional three years of vesting for benefit level increases occurring on or after January 1, 2010, helps promote retention of key executive officers.

28 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

Benefit Levels

The chief executive officer recommends benefit level increases to the compensation committee for participants except himself. The chief executive officer considers, among other things, the participant’s salary in relation to the salary ranges that correspond with the SISP benefit levels, the participant’s performance, the performance of the applicable business segment or the company, and the cost associated with the benefit level increase.

The chief executive recommended, and the compensation committee approved, a 2014 SISP benefit level increase for Mr. Schwartz. The benefit level increase corresponded to one level below which Mr. Schwartz’s 2014 salary would otherwise qualify. The recommendation was to recognize Mr. Schwartz’s continued growth in assuming the top financial role at the company.

The following table reflects our named executive officers’ SISP levels as of December 31, 2014:



	December 31, 2014
	Annual SISP Benefits
Name	Survivor ($)	Retirement ($)
Name	Survivor ($)	Retirement ($)
David L. Goodin	552,960	276,480
Doran N. Schwartz	262,464	131,232
J. Kent Wells	N/A	N/A
Jeffrey S. Thiede	N/A	N/A
Steven L. Bietz	386,640	193,320

Nonqualified Defined Contribution Plan

The company adopted the Nonqualified Defined Contribution Plan, or NQDCP, effective January 1, 2012, to provide deferred compensation for a select group of management or highly compensated employees who do not participate in the SISP. The compensation committee, upon recommendation from the chief executive officer, determines which employees will participate in the NQDCP for any year. The compensation committee determines the amount of employer contributions under the plan, which are credited to plan accounts and not funded. After satisfying a four-year vesting requirement for each contribution, the contributions and investment earnings will be distributed to the executive in a lump sum upon separation from service with the company or in annual installments commencing upon the later of (i) separation from service and (ii) age 65. The four-year vesting requirement is waived if the participant dies while employed by the company.

The committee, upon recommendation of the chief executive officer, selected Mr. Thiede as a participant for 2014 with an employer contribution of $75,000 or 18.75% of his base salary as of January 1, 2014. The contribution was awarded to recognize his leadership in the construction services segment’s achievement of a twelve-month return on invested capital, measured at June 30, 2013, of 16.1% as compared to a median return on invested capital of 9.5% at the relevant companies in our performance graph peer group. We believe that Mr. Thiede’s participation in this plan and the four-year vesting requirement enhances retention since he cannot participate in any of our defined benefit retirement plans.

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 places a limit of $1 million on the amount of compensation paid to certain officers that we may deduct as a business expense in any tax year unless, among other things, the compensation qualifies as performance-based compensation, as that term is used in Section 162(m). Generally, long-term incentive compensation and annual incentive awards for our chief executive officer and those executive officers whose overall compensation is likely to exceed $1 million are structured to be deductible for purposes of Section 162(m) of the Internal Revenue Code, but we may pay compensation to an executive officer that is not deductible. All annual or long-term incentive compensation paid to our named executive officers in 2014 satisfied the requirements for deductibility, except for $195,645 paid to Mr. Thiede in 2014 attributable to his 2013 annual incentive compensation. This incentive award was granted to Mr. Thiede prior to his promotion in May 2013 under a plan that was not approved by stockholders for purposes of Section 162(m) of the Code.

Section 409A of the Internal Revenue Code imposes additional income taxes on executive officers for certain types of deferred compensation if the deferral does not comply with Section 409A. We have amended our compensation plans and arrangements affected by Section 409A with the objective of not triggering any additional income taxes under Section 409A.

Section 4999 of the Internal Revenue Code imposes an excise tax on payments to executives and others of amounts that are considered to be related to a change of control if they exceed levels specified in Section 280G of the Internal Revenue Code. To the extent a change in

MDU Resources Group, Inc. Proxy Statement 29

Proxy Statement

control triggers liability for an excise tax, payment of the excise tax will be made by the individual. The company will not pay the excise tax. We do not consider the potential impact of Section 4999 or 280G when designing our compensation programs.

The compensation committee also considers the accounting and cash flow implications of various forms of executive compensation. In our financial statements, we record salaries and annual incentive compensation as expenses in the amount paid, or to be paid, to the named executive officers. For our equity awards, accounting rules also require that we record an expense in our financial statements. We calculate the accounting expense of equity awards to employees in accordance with Financial Accounting Standards Board generally accepted accounting principles for stock-based compensation.

Stock Ownership Requirements

We instituted stock ownership guidelines on May 5, 1993, which we revised in November 2010 to provide that executives who participate in our Long-Term Performance-Based Incentive Plan are required within five years to own our common stock equal to a multiple of their base salaries. Stock owned through our 401(k) plan or by a spouse is considered in ownership calculations. Unvested performance shares and other unvested equity awards are not considered in ownership calculations. The level of stock ownership compared to the requirements is determined based on the closing sale price of the stock on the last trading day of the year and base salary at December 31 of each year. Each February the compensation committee receives a report on the status of stock holdings by executives. The committee may, in its sole discretion, grant an extension of time to meet the ownership requirements or take such other action as it deems appropriate to enable the executive to achieve compliance with the policy. The table shows the named executive officers’ holdings as of December 31, 2014:



Name	Assigned Guideline Multiple of Base Salary		Actual Holdings as a Multiple of Base Salary	Number of Years at Guideline Multiple (#)
David L. Goodin		4X	2.25	2.00	¹
Doran N. Schwartz		3X	2.79	4.87	²
J. Kent Wells		3X	1.09	3.67	³
Jeffrey S. Thiede		3X	0.13	1.00	⁴

¹Participant must meet ownership requirement by January 1, 2018.
²Participant must meet ownership requirement by February 17, 2015.
³ Participant must meet ownership requirement by May 1, 2016.
⁴ Participant must meet ownership requirement by January 1, 2019.

The compensation committee may consider the policy and the executive’s stock ownership in determining compensation. The committee, however, did not do so with respect to 2014 compensation.

Policy Regarding Hedging Stock Ownership

Our executive compensation policy prohibits Section 16 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 Security Ownership section of the proxy statement for our policy on margin accounts and pledging of our stock.

Compensation Committee Report

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

Incentive Awards

Annual Incentive

On February 12, 2014, the compensation committee recommended the 2014 annual incentive award opportunities for our named executive officers and the board approved these opportunities at its meeting on February 13, 2014. These award opportunities are reflected in the Grants of Plan-Based Awards table at grant on February 13, 2014, in columns (c), (d), and (e) and in the Summary Compensation Table as earned with respect to 2014 in column (g).

Executive officers may receive a payment of annual cash incentive awards based upon achievement of annual performance measures with a threshold, target, and maximum level. A target incentive award is established based on a percent of the executive’s base salary. Based upon achievement of goals, actual payment may range from 0% to approximately 207% of the target for Messrs. Goodin and Schwartz, from 0% to 200% of the target for Messrs. Wells and Bietz, and from 0% to 237.5% of the target for Mr. Thiede.

In order to be eligible to receive a payment of an annual incentive award under the Long-Term Performance-Based Incentive Plan, Messrs. Goodin, Wells, and Thiede must have remained employed by the company through December 31, 2014, unless the compensation

32 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

committee determines otherwise. The committee has full discretion to determine the extent to which goals have been achieved, the payment level, whether any final payment will be made, and whether to adjust awards downward based upon individual performance. Unless otherwise determined and established in writing by the compensation committee within 90 days of the beginning of the performance period, the performance goals may not be adjusted if the adjustment would increase the annual incentive award payment. The compensation committee may use negative discretion and adjust any annual incentive award payment downward, using any subjective or objective measures as it shall determine. The application of any reduction, and the methodology used in determining any such reduction, is in the sole discretion of the compensation committee.

With respect to annual incentive awards granted pursuant to the MDU Resources Group, Inc. Executive Incentive Compensation Plan, which includes Messrs. Schwartz and Bietz, participants who retire during the year at age 65 pursuant to their employer’s bylaws remain eligible to receive an award. Subject to the compensation committee’s discretion, executives who terminate employment for other reasons are not eligible for an award. The compensation committee has full discretion to determine the extent to which goals have been achieved, the payment level, and whether any final payment will be made. Once performance goals are approved by the committee for executive incentive compensation plan awards, the committee generally does not modify the goals. However, if major unforeseen changes in economic and environmental conditions or other significant factors beyond the control of management substantially affected management’s ability to achieve the specified performance goals, the committee, in consultation with the chief executive officer, may modify the performance goals. Such goal modifications will only be considered in years of unusually adverse or favorable external conditions.

Annual incentive awards earned for Messrs. Goodin and Schwartz were determined based on achievement of performance goals at the following business segments - (i) pipeline and energy services, (ii) exploration and production, (iii) construction services, (iv) construction materials and contracting, and (v) electric and natural gas distribution - and were calculated as follows:



	Column A Percentage of Annual Incentive Target Achieved		Column B Percentage of Average Invested Capital		Column A x Column B



Pipeline and Energy Services	175.5	%	11.1	%	19.5	%
Exploration and Production	49.3	%	26.7	%	13.2	%
Construction Services	214.8	%	6.6	%	14.2	%
Construction Materials and Contracting	96.3	%	19.6	%	18.9	%
Electric and Natural Gas Distribution	68.9	%	36.0	%	24.8	%
Total (Payout Percentage)					90.6	%

Messrs. Wells, Thiede, and Bietz had 2014 award opportunities based 75% on performance goals at their respective segments and 25% on MDU Resources Group, Inc.’s earnings per share.

The 2014 target for the MDU Resources Group 25% award opportunity was established based on consolidated earnings per share, adjusted as described in the footnote to the table below describing Mr. Wells’ 75% award opportunity and also adjusted to exclude the effect on earnings at the company level of intersegment eliminations.

The MDU Resources Group 25% award opportunity was as follows:



MDU Resources Group, Inc.’s adjusted consolidated 2014 earnings per share results as a % of target		Corresponding payment of annual incentive target based on adjusted consolidated earnings per share results
Less than 85%		0%

Long-Term Incentive

On February 12, 2014, the compensation committee recommended long-term incentive grants for the named executive officers in the form of performance shares, and the board approved these grants at its meeting on February 13, 2014. These grants are reflected in columns (f), (g), (h), and (l) of the Grants of Plan-Based Awards table and in column (e) of the Summary Compensation Table.

If the company’s 2014-2016 total stockholder return is positive, from 0% to 200% of the target grant will be paid out in February 2017, depending on our 2014-2016 total stockholder return compared to the total three-year stockholder returns of companies in our performance graph peer group. The payout percentage is determined as follows:



The Company’s Percentile Rank		Payout Percentage of February 13, 2014 Grant
75th or higher		200%
50th		100%
25th		20%
Less than 25th		0%

If the common stock of a company in the peer group ceases to be traded at any time during the 2014-2016 performance period, the company will be deleted from the peer group. Percentile rank will be calculated without regard to the return of the deleted company. If MDU Resources Group, Inc. or a company in the peer group spins off a segment of its business, the shares of the spun-off entity will be treated as a cash dividend that is reinvested in MDU Resources Group, Inc. or the company in the peer group.

If the company’s 2014-2016 total stockholder return is negative, the number of shares otherwise earned, if any, for the performance period will be reduced in accordance with the following table:



Total Stockholder Return		Reduction in Award
0% through -5%		50%
-5.01% through -10%		60%
-10.01% through -15%		70%
-15.01% through -20%		80%
-20.01% through -25%		90%
-25.01% or below		100%

¹	Grandfathered under Section 409A.

²	Not grandfathered under Section 409A.

³	Years of credited service only affects vesting under SISP I and SISP II. The number of years of credited service in the table reflects the years of vesting service completed in SISP I and SISP II as of December 31, 2014, rather than total years of service with the company. Ten years of vesting service is required to obtain the full benefit under these plans. The present value of accumulated benefits was calculated by assuming the named executive officer would have ten years of vesting service on the assumed benefit commencement date; therefore, no reduction was made to reflect actual vesting levels.

⁴	Benefit level increases granted under SISP II on or after January 1, 2010 require an additional three years of vesting service for the increase. Mr. Goodin received a benefit increase effective January 1, 2012, Messrs. Goodin and Schwartz received benefit level increases effective January 1, 2013, and Mr. Schwartz received a benefit level increase effective January 1, 2014; the present value of their accumulated benefits was calculated assuming that the additional vesting requirements would be met.

⁵	The number of years of credited service under the SISP excess reflects the years of credited benefit service in the appropriate pension plan as of December 31, 2009, when the MDU and WBI pension plans were frozen, rather than the years of participation in the SISP excess. We reflect years of credited benefit service in the appropriate pension plan because the SISP excess provides a benefit that is based on benefits that would have been payable under the MDU and WBI pension plans absent Internal Revenue Code limitations.

⁶	Messrs. Wells and Thiede are not eligible to participate in the pension plans and do not participate in the SISP.

The amounts shown for the pension plan and SISP excess represent the actuarial present values of the executives’ accumulated benefits accrued as of December 31, 2014, calculated using a 3.50%, 3.67%, and 3.76% discount rate for the SISP excess, MDU pension plan, and WBI pension plan, respectively, the 2014 IRS Static Mortality Table for post-retirement mortality, and no recognition of future salary increases or pre-retirement mortality. The assumed retirement age for these benefits was age 60 for Messrs. Goodin, Schwartz, and Bietz. This is the earliest age at which the executives could begin receiving unreduced benefits. The amounts shown for the SISP I and SISP II were determined using a 3.50% discount rate and assume benefits commenced at age 65.

Pension Plan

Messrs. Goodin and Schwartz participate in the MDU Resources Group, Inc. Pension Plan for Non-Bargaining Unit Employees, which we refer to as the MDU pension plan. Mr. Bietz participates in the Williston Basin Interstate Pipeline Company Pension Plan, which we refer to as the WBI pension plan. Pension benefits under the pension plans are based on the participant’s average annual salary over the 60 consecutive month period in which the participant received the highest annual salary during the participant’s final 10 years of service. For this purpose, only a participant’s salary is considered; incentives and other forms of compensation are not included. Benefits are determined by multiplying (1) the participant’s years of credited service by (2) the sum of (a) the average annual salary up to the social security

integration level times 1.1% and (b) the average annual salary over the social security integration level times 1.45%. The maximum years of service recognized when determining benefits under the pension plans is 35. Pension plan benefits are not reduced for social security benefits.

Both of the pension plans were amended to cease benefit accruals as of December 31, 2009, meaning the normal retirement benefit will not change. The years of credited service in the table reflect the named executive officers’ years of credited service as of December 31, 2009.

To receive unreduced retirement benefits under the MDU pension plan and the WBI pension plan, participants must either remain employed until age 60 or elect to defer commencement of benefits until age 60. Participants whose employment terminates between the ages of 55 and 60, with 5 years of service under the MDU pension plan and the WBI pension plan, are eligible for early retirement benefits. Early retirement benefits are determined by reducing the normal retirement benefit by 0.25% per month for each month before age 60. If a participant’s employment terminates before age 55, the same reduction applies for each month the termination occurs before age 62, with the reduction capped at 21%.

Benefits for single participants under the pension plans are paid as straight life annuities, and benefits for married participants are paid as actuarially reduced annuities with a survivor benefit for spouses, unless participants choose otherwise. Participants hired before January 1, 2004, who terminate employment before age 55, may elect to receive their benefits in a lump sum. Mr. Goodin would have been eligible for a lump sum if he had retired on December 31, 2014.

The Internal Revenue Code limits the amounts paid under the pension plans and the amount of compensation recognized when determining benefits. In 2009, when the pension plans were frozen, the maximum annual benefit payable under the pension plans was $195,000 and the maximum amount of compensation recognized when determining benefits was $245,000.

Supplemental Income Security Plan

We also offer select key managers and executives benefits under our defined benefit nonqualified retirement plan, which we refer to as the Supplemental Income Security Plan or SISP. Messrs. Goodin, Schwartz, and Bietz participate in the SISP. Benefits under the SISP consist of:


•	a supplemental retirement benefit intended to augment the retirement income provided under the pension plans – we refer to this benefit as the regular SISP benefit


•	an excess retirement benefit relating to Internal Revenue Code limitations on retirement benefits provided under the pension plans – we refer to this benefit as the SISP excess benefit and


•	death benefits – we refer to these benefits as the SISP death benefit.

SISP benefits are forfeited if the participant’s employment is terminated for cause.

Regular SISP Benefits and Death Benefits

Regular SISP benefits and death benefits are determined by reference to one of two schedules attached to the SISP – the original schedule or the amended schedule. Our compensation committee, after receiving recommendations from our chief executive officer, determines the level at which participants are placed in the schedules. A participant’s placement is generally, but not always, determined by reference to the participant’s annual base salary. Benefit levels in the amended schedule, which became effective on January 1, 2010, are 20% lower than the benefit levels in the original schedule. The amended schedule applies to new participants and participants who receive a benefit level increase on or after January 1, 2010. One of the named executive officers, Mr. Schwartz, received a benefit level increase effective January 1, 2014, which requires three years of vesting.

Participants can elect to receive (1) the regular SISP benefit only, (2) the SISP death benefit only, or (3) a combination of both. Regardless of the participant’s election, if the participant dies before the regular SISP benefit would commence, only the SISP death benefit is provided. If the participant elects to receive both a regular SISP benefit and a SISP death benefit, each of the benefits is reduced proportionately.

The regular SISP benefits reflected in the table above are based on the assumption that the participant elects to receive only the regular SISP benefit. The present values of the SISP death benefits that would be provided if the named executive officers had died on December 31, 2014, prior to the commencement of regular SISP benefits, are reflected in the table that appears in the section entitled “Potential Payments upon Termination or Change of Control.”

38 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

Regular SISP benefits that were vested as of December 31, 2004, and were grandfathered under Section 409A of the Internal Revenue Code remain subject to SISP provisions then in effect, which we refer to as SISP I benefits. Regular SISP benefits that are subject to Section 409A of the Internal Revenue Code, which we refer to as SISP II benefits, are governed by amended provisions intended to comply with Section 409A. Participants generally have more discretion with respect to the distributions of their SISP I benefits.

The time and manner in which the regular SISP benefits are paid depend on a variety of factors, including the time and form of benefit elected by the participant and whether the benefits are SISP I or SISP II benefits. Unless the participant elects otherwise, the SISP I benefits are paid over 180 months, with benefits commencing when the participant attains age 65 or, if later, when the participant retires. The SISP II benefits commence when the participant attains age 65 or, if later, when the participant retires, subject to a six-month delay if the participant is subject to the provisions of Section 409A of the Internal Revenue Code that require delayed commencement of these types of retirement benefits. The SISP II benefits are paid over 180 months or, if commencement of payments is delayed for six months, 173 months. If the commencement of benefits is delayed for six months, the first payment includes the payments that would have been paid during the six-month period plus interest equal to one-half of the annual prime interest rate on the participant’s last date of employment. If the participant dies after the regular SISP benefits have begun but before receipt of all of the regular SISP benefits, the remaining payments are made to the participant’s designated beneficiary.

Rather than receiving their regular SISP I benefits in equal monthly installments over 15 years commencing at age 65, participants can elect a different form and time of commencement of their SISP I benefits. Participants can elect to defer commencement of the regular SISP I benefits. If this is elected, the participant retains the right to receive a monthly SISP death benefit if death occurs prior to the commencement of the regular SISP I benefit.

Participants also can elect to receive their SISP I benefits in one of three actuarially equivalent forms – a life annuity, 100% joint and survivor annuity, or a joint and two-thirds joint and survivor annuity, provided that the cost of providing these actuarial equivalent forms of benefits does not exceed the cost of providing the normal form of benefit. Neither the election to receive an actuarially equivalent benefit nor the administrator’s right to pay the regular SISP benefit in the form of an actuarially equivalent lump sum are available with respect to SISP II benefits.

To promote retention, the regular SISP benefits are subject to the following 10-year vesting schedule:


•	0% vesting for less than 3 years of participation


•	20% vesting for 3 years of participation


•	40% vesting for 4 years of participation and


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

There is an additional vesting requirement on benefit level increases for the regular SISP benefit granted on or after January 1, 2010. The requirement applies only to the increased benefit level. The increased benefit vests after the later of three additional years of participation in the SISP or the end of the regular vesting schedule described above. The additional three-year vesting requirement for benefit level increases is pro-rated for participants who are officers, attain age 65, and, pursuant to the company’s bylaws, are required to retire prior to the end of the additional vesting period as follows:


•	33% of the increase vests for participants required to retire at least one year but less than two years after the increase is granted and


•	66% of the increase vests for participants required to retire at least two years but less than three years after the increase is granted.

The benefit level increases of participants who attain age 65 and are required to retire pursuant to the company’s bylaws will be further reduced to the extent the participants are not fully vested in their regular SISP benefit under the 10-year vesting schedule described above. The additional vesting period associated with a benefit level increase may be waived by the compensation committee.

SISP death benefits become fully vested if the participant dies while actively employed. Otherwise, the SISP death benefits are subject to the same vesting schedules as the regular SISP benefits.

The SISP also provides that if a participant becomes totally disabled, the participant will continue to receive credit for up to two additional years under the SISP as long as the participant is totally disabled during such time. Since the named executive officers other than Mr. Goodin, in his upgrades, and Mr. Schwartz are fully vested in their SISP benefits, this would not result in any incremental benefit for the named executive officers other than Messrs. Goodin and Schwartz. The present value of these two additional years of service for Messrs. Goodin and Schwartz is reflected in the table in “Potential Payments upon Termination or Change of Control” below.

MDU Resources Group, Inc. Proxy Statement 39

SISP Excess Benefits

SISP excess benefits are equal to the difference between (1) 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 (2) the actual benefits payable to the participant under the pension plans. Participants are only eligible for the SISP excess benefits if (1) the participant is fully vested under the pension plan, (2) the participant’s employment terminates prior to age 65, and (3) benefits under the pension plan are reduced due to limitations under the Internal Revenue Code on plan compensation. Effective January 1, 2005, participants who were not then vested in the SISP excess benefits were also required to remain actively employed by the company until age 60. In 2009, the plan was amended to limit eligibility for the SISP excess benefit to current SISP participants (1) who were already vested in the SISP excess benefit or (2) who would become vested in the SISP excess benefits if they remain employed with the company until age 60. The plan was further amended to freeze the SISP excess benefits to a maximum of the benefit level payable based on the participant’s years of service and compensation level as of December 31, 2009. Mr. Goodin must remain employed until age 60 to become entitled to his SISP excess benefit. Mr. Bietz would be entitled to the SISP excess benefit if he were to terminate employment prior to age 65. Messrs. Schwartz, Wells, and Thiede are not eligible for this 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. If a participant who dies prior to age 65 elected a joint and survivor benefit, the survivor’s SISP excess benefit is paid until the date the participant would have attained age 65.

Deferral of Annual Incentive Compensation

Participants in the executive incentive compensation plans may elect to defer up to 100% of their annual incentive awards. Deferred amounts accrue interest at a rate determined annually by the compensation committee. The interest rate in effect for 2014 was 4.67% or the “Moody’s Rate,” which is the average of (i) the number that results from adding the daily Moody’s U.S. Long-Term Corporate Bond Yield Average for “A” rated companies as of the last day of each month for the 12-month period ending October 31 and dividing by 12 and (ii) the number that results from adding the daily Moody’s U.S. Long-Term Corporate Bond Yield Average for “Baa” rated companies as of the last day of each month for the 12-month period ending October 31 and dividing by 12. 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 granted. The amounts will be paid in accordance with the participant’s election in a lump sum or in monthly installments not to exceed 120 months. In the event of a change of control, all amounts become immediately payable.

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 total 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 management or highly compensated employees who do not participate in the SISP. The compensation committee determines the amount of employer contributions under the Nonqualified Defined Contribution Plan, which are credited to plan accounts and not funded. After satisfying a four-year vesting requirement for each contribution, the contributions and investment earnings will be distributed to the executive in a lump sum upon separation from service with the company or in annual installments commencing 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.

Potential Payments upon Termination or Change of Control

The following tables show the payments and benefits our named executive officers would receive in connection with a variety of employment termination scenarios and upon a change of control. For the named executive officers, the information assumes the terminations and the change of control occurred on December 31, 2014. All of the payments and benefits described below would be provided by the company or its subsidiaries.

The tables exclude compensation and benefits provided under plans or arrangements that do not discriminate in favor of the named executive officers and that are generally available to all salaried employees, 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 include amounts under the Nonqualified Defined Contribution Plan, but do not include the named executive officers’ deferred annual incentive compensation. See the Pension Benefits for 2014 table and the Nonqualified Deferred Compensation for 2014 table, and accompanying narratives, for a description of the named executive officers’ accumulated benefits under our qualified defined benefit pension plans, the Nonqualified Defined Contribution Plan, and their deferred annual incentive compensation.

The calculation of the present value of excess SISP benefits our named executive officers would be entitled to upon termination of employment under the SISP was computed based on calculations assuming an age rounded to the nearest whole year of age. Actual payments may differ. The terms of the excess SISP benefit are described following the Pension Benefits for 2014 table.

We provide disability benefits to some of our salaried employees equal to 60% of their base salary, subject to a cap on the amount of base salary taken into account when calculating benefits. For officers, the limit on base salary is $200,000. For other salaried employees, the limit is $100,000. For all salaried employees, disability payments continue until age 65 if disability occurs at or before age 60 and for 5 years if disability occurs between the ages of 60 and 65. Disability benefits are reduced for amounts paid as retirement benefits. The amounts in the tables 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. As the tables reflect, the reduction for amounts paid as retirement benefits would eliminate disability benefits assuming a termination of employment on December 31, 2014 for Mr. Bietz.

Upon a change of control, share-based awards granted under our Long-Term Performance-Based Incentive Plan vest and non-share-based awards are paid in cash. All performance share awards for Messrs. Goodin, Schwartz, Wells, Thiede, and Bietz and the annual incentives for Messrs. Goodin, Wells, and Thiede, which were awarded under the Long-Term Performance-Based Incentive Plan, would vest at their target levels. For this purpose, the term “change of control” is defined as:


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


•	a change in a majority of our board of directors since April 22, 1997, without the approval of a majority of the board members as of April 22, 1997, or whose election was approved by such 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 41

Proxy Statement

Performance share awards will be forfeited if the participant’s employment terminates for any reason before the participant has reached age 55 and completed 10 years of service. Performance shares and related dividend equivalents for those participants whose employment is terminated other than for cause after the participant has reached age 55 and completed 10 years of service will be pro-rated as follows:


•	if the termination of employment occurs during the first year of the performance period, the shares are forfeited


•	if the termination of employment occurs during the second year of the performance period, the executive receives a pro-rated portion of any performance shares earned based on the number of months employed during the performance period and


•	if the termination of employment occurs during the third year of the performance period, the executive receives the full amount of any performance shares earned.

As of December 31, 2014, Messrs. Goodin, Schwartz, Wells, and Thiede had not satisfied this requirement. Accordingly, if a December 31, 2014 termination other than for cause without a change of control is assumed, the named executive officers’ 2014-2016 performance share awards would be forfeited; any amounts earned under the 2013-2015 performance share award for Mr. Bietz would be reduced by one-third and such awards for Messrs. Goodin, Schwartz, and Wells would be forfeited; any amounts earned under the 2012-2014 performance share awards for Mr. Bietz would not be reduced and the award for Messrs. Goodin, Schwartz, and Wells would be forfeited. Mr. Thiede had no 2013-2015 or 2012-2014 performance share awards. The number of performance shares earned following a termination depends on actual performance through the full performance period. As actual performance for the 2012-2014 performance share awards has been determined, the amounts for these awards in the event of a termination without a change of control were based on actual performance, which resulted in vesting of 0% of the target award. For the 2013-2015 performance share awards, because we do not know what actual performance through the entire performance period will be, we have assumed target performance will be achieved and, therefore, show two-thirds of the target award. No amounts are shown for the 2014-2016 performance share awards because such awards would be forfeited. Although vesting would only occur after completion of the performance period, the amounts shown in the tables were not reduced to reflect the present value of the performance shares that could vest. Dividend equivalents attributable to earned performance shares would also be paid. Dividend equivalents accrued through December 31, 2014, are included in the amounts shown.

The value of the vesting of performance shares shown in the tables was determined by multiplying the number of performance shares that would vest due to termination or a change of control by the closing price of our stock on December 31, 2014.

The compensation committee may consider providing severance benefits on a case-by-case basis for employment terminations. The compensation committee adopted a checklist of factors in February 2005 to consider when determining whether any such severance benefits should be paid. The tables do not reflect any such severance benefits, as these benefits are made in the discretion of the committee on a case-by-case basis and it is not possible to estimate the severance benefits, if any, that would be paid.

Proxy Statement

Directors are reimbursed for all reasonable travel expenses including spousal expenses in connection with attendance at meetings of the board and its committees. All amounts together with any other perquisites were below the disclosure threshold for 2014.

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.

Our director stock ownership policy contained in our corporate governance guidelines requires each director to 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 participation in our director stock plans will be considered in ownership calculations as will ownership of our common stock by a spouse. A director is allowed five years commencing January 1 of the year following the year of that 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. For stock ownership, please see “Security Ownership.”

Narrative Disclosure of our Compensation Policies and Practices
as They Relate to Risk Management

The human resources department has conducted an assessment of the risks arising from our compensation policies and practices for all employees and concluded that none of these risks is reasonably likely to have a material adverse effect on the company. Based on the human resources department’s assessment and taking into account information received from the risk identification process, senior management and our management policy committee concluded that risks arising from our compensation policies and practices for all employees are not reasonably likely to have a material adverse effect on the company. After review and discussion with senior management, the compensation committee concurred with this assessment.

As part of its assessment of the risks arising from our compensation policies and practices for all employees, the human resources department identified the principal areas of risk faced by the company that may be affected by our compensation policies and practices for all employees, including any risks resulting from our operating businesses’ compensation policies and practices. 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 that promotes careful consideration of financial assumptions


•	limitation on business acquisitions without board approval


•	employee integrity training programs and anonymous reporting systems


•	quarterly risk assessment and internal control 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 comparison of executive compensation to total stockholder return ratio to the ratio for the performance graph peer group (PEER Analysis)


•	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 or long-term incentives tied to the company’s financial performance


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

MDU Resources Group, Inc. Proxy Statement 47

Proxy Statement


•	negative discretion to adjust any annual or long-term incentive award payment downward


•	use of caps on annual incentive awards (maximum of 250% of target) and long-term incentive stock grant awards (200% target)


•	discretionary clawbacks on incentive payments in the event of a financial restatement


•	use of performance shares, rather than stock options or stock appreciation rights, as equity component of incentive compensation


•	use of performance shares with a relative total stockholder return performance goal and mandatory reduction in award if total stockholder return is negative


•	use of three-year performance periods to discourage short-term risk-taking


•	substantive incentive goals measured primarily by return on invested capital, earnings, and earnings per share criteria, which encourage balanced performance and are important to stockholders


•	use of financial performance metrics that are readily monitored and reviewed


•	regular review of the appropriateness of the companies in the performance graph peer group


•	stock ownership requirements for executives participating in the MDU Resources Group, Inc. Long-Term Performance-Based Incentive Plan and the board


•	mandatory holding periods for 50% of any net after-tax shares earned under long-term incentive awards granted in 2011 and thereafter and

RELATED PERSON TRANSACTION DISCLOSURE

The board of directors has adopted a policy for the review of related person transactions. This policy is contained in our corporate governance guidelines, which are posted on our website at http://www.mdu.com/docs/default-source/Governance/corporategovernanceguidelines.pdf. The audit committee reviews any transaction, arrangement or relationship, or series thereof:


•	in which we are or will be a participant


•	the amount involved exceeds $120,000 and


•	a related person has or will have a 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 may be required to be disclosed under the Securities and Exchange Commission’s rules, the general counsel furnishes the information to the chairman 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.

CORPORATE GOVERNANCE

Director Independence

The board of directors has adopted guidelines on director independence that are included in our corporate governance guidelines, which are available for review on our corporate website at http://www.mdu.com/docs/default-source/Governance/corporategovernanceguidelines.pdf. The board of directors has determined that current directors Thomas Everist, Karen B. Fagg, Mark A. Hellerstein, A. Bart Holaday, Dennis W. Johnson, William E. McCracken, Patricia L. Moss, Harry J. Pearce, and John K. Wilson:


•	have no material relationship with us and


•	are independent in accordance with our director independence guidelines and the New York Stock Exchange listing standards.

The board of directors previously determined that Thomas C. Knudson, who did not stand for re-election at the 2014 annual meeting, had no material relationship with us and was independent in accordance with our director independence guidelines and the New York Stock Exchange listing standards during the time he was a director.

In determining director independence, the board of directors reviewed and considered information about any transactions, relationships, and arrangements between the independent 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:

•

Business relationships with entities with which a director is affiliated: Purchase by the company in the ordinary course of business of cloud-based services for meeting SEC filing requirements from Workiva Inc. (formerly known as WebFilings, LLC), a company in which Mr. Everist owns less than 1% of the outstanding shares of Class A Common Stock. Payments by the company to Workiva in any of the last three fiscal years did not exceed the greater of $1 million or 2% of Workiva’s consolidated gross revenues. The transaction was entered into on substantially the same terms as those prevailing at the time for comparable transactions with non-affiliated entities. Dakota Prairie Refining, LLC (DPR), a limited liability company jointly owned by WBI Energy, Inc., an indirect wholly-owned subsidiary of the company, and Calumet Specialty Products Partners, L.P., entered into agreements in September 2013 with the City of Dickinson, North Dakota (City) under which DPR will pay the City for supplying treated industrial water to DPR and for treating DPR’s waste water. The agreements also require the City to reimburse DPR for certain construction costs related to pipelines and related facilities constructed by DPR that benefit the City. Mr. Johnson is president of the City board of commissioners. Mr. Johnson abstained from discussion and voting on the agreements. The payments from DPR to the City and from the City to DPR in either of the last two fiscal years did not exceed the greater of $1 million or 2% of the City’s consolidated gross revenues.

•

Charitable contributions by the MDU Resources Foundation (Foundation) to nonprofit organizations, where a director, or a director’s spouse, serves or has served as a director, chair, or vice chair of the board of trustees, trustee or member of the organization or related entity: Charitable contributions by the Foundation to Sanford Health Foundation, Billings Catholic Schools Foundation, the Denver Children’s Advocacy Center, Community Resources Inc., the University of North Dakota Foundation, the University of Jamestown and its foundation, the City of Dickinson, and the St. Charles Foundation. None of the contributions made to any of these nonprofit entities during the last three fiscal years exceeded in any single year the greater of $1 million or 2% of the relevant entity’s consolidated gross revenues.

•

Ownership by directors of company stock: Ownership by Mr. Everist, directly or indirectly, of 1,143,533 shares of company stock, which represented less than 1% of our outstanding common stock, at December 31, 2014, approximately 1.14 million shares, which represented less than 1% of our outstanding common stock, at December 31, 2013, and approximately 1.89 million shares, which represented approximately 1% of our outstanding common stock, at December 31, 2012.

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 2014, no directors submitted resignations under this requirement.

Code of Conduct

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

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 New York Stock Exchange listing standards

by posting such information on our website at http://www.mdu.com/docs/default-source/Governance/leadingintegrity_2014.pdf.

Board Leadership Structure and Board’s Role in Risk Oversight

The board separated the positions of chairman of the board and chief executive officer in 2006 and elected Harry J. Pearce, a non-employee independent director, as our chairman. Separating these positions allows our chief executive officer to focus on the full-time job of running our business, while allowing the chairman of the board to lead the board in its fundamental role of providing advice to and independent oversight of management. The board believes this structure recognizes the time, effort, and energy that the chief executive officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chairman, 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 chairman is a means to ensure the chief executive officer is accountable for managing the company in close alignment with the interests of stockholders. An independent chairman avoids the conflicts of interest that arise when the chairman and chief executive officer positions are combined and more effectively manages relationships between the board and the chief executive officer. An independent chairman is in a better position to encourage frank and lively discussions and to assure that the company has adequately assessed all appropriate business risks before adopting its final business plans and strategies. Our bylaws and corporate governance guidelines require that our chairman be independent. The board believes that having separate positions and having an independent outside director serve as chairman is the appropriate leadership structure for the company and demonstrates our commitment to good corporate governance.

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, environmental and regulatory risks, and others, such as the impact of competition, weather conditions, limitations on our ability to pay dividends, increased pension plan obligations, cyber attacks or acts of terrorism, and our ability to sell our exploration and production business. Management is responsible for the day-to-day management of risks the company faces, while 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 and functioning as designed.

54 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

The board believes that establishing the right “tone at the top” and that full and open communication between management and the board of directors are essential for effective risk management and oversight. Our chairman meets regularly with our president and chief executive officer and other senior officers 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. The board holds strategic planning sessions with senior management to discuss strategies, key challenges, and risks and opportunities for the company.

While the board is ultimately responsible for risk oversight at our company, our three 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 and compliance with legal and regulatory requirements, and, in accordance with New York Stock Exchange requirements, discusses policies with respect to risk assessment and risk management and their adequacy and effectiveness. Risk assessment 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, membership and structure, succession planning for our directors and executive officers, and corporate governance.

Board Meetings and Committees

During 2014, the board of directors held seven meetings. Each director attended at least 75% of the combined total meetings of the board and the committees on which the director served during 2014. Director attendance at our annual meeting of stockholders is left to the discretion of each director. Three directors attended our 2014 annual meeting of stockholders.

Harry J. Pearce was elected non-employee chairman of the board on August 17, 2006. Mr. Pearce served as lead director from February 15, 2001 to August 17, 2006. He presides at the executive session of the non-employee directors held in connection with each regularly scheduled quarterly board of directors meeting. The non-employee directors also meet in executive session with the chief executive officer at each regularly scheduled quarterly board of directors meeting. All of our non-employee directors are independent directors.

The board has a standing audit committee, compensation committee, and nominating and governance committee. These committees are composed entirely of independent directors.

The audit, compensation, and nominating and governance committees have charters, which are available for review on our website at

http://www.mdu.com/integrity/governance/board-charters-and-committees. Our corporate governance guidelines are available at

http://www.mdu.com/docs/default-source/Governance/corporategovernanceguidelines.pdf, and our Leading With Integrity Guide is also on our website at http://www.mdu.com/docs/default-source/Governance/leadingintegrity_2014.pdf.

Nominating and Governance Committee

The nominating and governance committee met four times during 2014. The committee members are Karen B. Fagg, chairman, A. Bart Holaday, William E. McCracken, and Patricia L. Moss.

The nominating and governance committee 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


•	corporate governance guidelines applicable to us.

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

MDU Resources Group, Inc. Proxy Statement 55

Proxy Statement

The committee identifies individuals qualified to become directors and recommends to the board the nominees for director 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, our management, consultants, and other individuals likely to possess an understanding of our business and knowledge concerning suitable director candidates.

Our corporate governance guidelines include our policy on consideration of director candidates recommended to us. We will consider candidates that our stockholders recommend. Stockholders may submit director candidate recommendations to the nominating and governance committee chairman in care of the secretary at MDU Resources Group, Inc., P.O. Box 5650, Bismarck, ND 58506-5650. Please include the following information:


•	the candidate’s name, age, business address, residence address, and telephone number


•	the candidate’s principal occupation


•	the class and number of shares of our stock owned by the candidate


•	a description of the candidate’s qualifications to be a director


•	whether the candidate would be an independent director and


•	any other information you believe is relevant with respect to the recommendation.

These guidelines provide information to stockholders who wish to recommend candidates for director for consideration by the nominating and governance committee. Stockholders who wish to actually nominate persons for election to our board at an annual meeting of stockholders must follow the procedures set forth in section 2.08 of our bylaws. You may obtain a copy of the bylaws by writing to the secretary of MDU Resources Group, Inc. at the address above. Our bylaws are also available on our website at http://www.mdu.com/integrity/governance/guidelines-and-bylaws. See also the section entitled “2016 Annual Meeting of Stockholders” later in the proxy statement.

There are no differences in the manner by which the committee evaluates director candidates recommended by stockholders and those recommended by other sources.

In evaluating director candidates, the committee 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, general management, human resources, marketing, operations, public affairs, law, technology, and operations abroad


•	background in publicly traded companies


•	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


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

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

As indicated above, when identifying nominees to serve as director, the nominating and governance committee will consider candidates with diverse business and professional experience, skills, gender, and ethnic background, as appropriate, in light of the current composition and

needs of the board. The nominating and governance committee assesses the effectiveness of this policy annually in connection with the nomination of directors for election at the annual meeting of stockholders. The composition of the current board reflects diversity in business and professional experience, skills, and gender.

The committee generally will hire an outside firm to perform a background check on potential nominees.

Audit Committee

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

The audit committee met eight times during 2014. The audit committee members are Dennis W. Johnson, chairman, Mark A. Hellerstein, A. Bart Holaday, and John K. Wilson. The board of directors has determined that Messrs. Johnson, Hellerstein, Holaday, and Wilson are “audit committee financial experts” as defined by Securities and Exchange Commission regulations and meet the independence standard for audit committee members under our director independence guidelines, the New York Stock Exchange listing standards, and Securities and Exchange Commission 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 audit committee:


•	assists the board’s oversight of


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


◦	our compliance with legal and regulatory requirements


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


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


◦	risk management in the audit committee’s areas of responsibility and


•	arranges for the preparation of and approves the report that Securities and Exchange Commission rules require we include in our annual proxy statement.

Audit Committee Report

In connection with our financial statements for the year ended December 31, 2014, the audit committee has (1) reviewed and discussed the audited financial statements with management; (2) discussed with the independent registered public accounting firm (the “Auditors”) the matters required to be discussed by Public Company Accounting Oversight Board Auditing Standard No. 16, Communications with Audit Committees; and (3) received the written disclosures and the letter from the Auditors required by applicable requirements of the Public Company Accounting Oversight Board regarding the Auditors’ communications with the audit committee concerning independence, and has discussed with the Auditors their independence.

Based on the review and discussions referred to in items (1) through (3) of the above paragraph, the audit committee recommended to the board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2014, for filing with the Securities and Exchange Commission.

Proxy Statement

Compensation Committee

The compensation committee met four times during 2014. The compensation committee members are Thomas Everist, chairman, Karen B. Fagg, William E. McCracken, and Patricia L. Moss. Thomas C. Knudson served on the committee until the 2014 annual meeting, when he did not stand for re-election. William E. McCracken joined the committee effective May 15, 2014.

The compensation committee’s responsibilities, as set forth in its charter, include:


•	review and recommend changes to the board regarding our executive compensation policies for directors and executives


•	evaluate the chief executive officer’s performance and, either as a committee or together with other independent directors as directed by the board, determine his or her compensation


•	recommend to the board the compensation of our other Section 16 officers and directors


•	establish goals, make awards, review performance and determine, or recommend to the board, awards earned under our annual and long-term incentive compensation plans


•	review and discuss with management the Compensation Discussion and Analysis and based upon such review and discussion, determine whether to recommend to the board that the Compensation Discussion and Analysis be included in our proxy statement and/or our Annual Report on Form 10-K


•	arrange for the preparation of and approve the compensation committee report to be included in our proxy statement and/or Annual Report on Form 10-K


•	assist the board in overseeing the management of risk in the committee’s areas of responsibility and


•	appoint, compensate, and oversee the work of any compensation consultant, legal counsel or other adviser retained by the compensation committee.

The compensation committee and the board of directors have sole and direct responsibility for determining compensation for our Section 16 officers and directors. The compensation committee makes recommendations to the board regarding compensation of all Section 16 officers, and the board then acts on the recommendations. The compensation committee and the board may not delegate their authority. They may, however, use recommendations from outside consultants, the chief executive officer, and the human resources department. The chief executive officer, the vice president-human resources, and general counsel regularly attend compensation committee meetings. The committee meets in executive session as needed. The 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 in the other years. The committee retained a compensation consultant in 2014 to prepare a competitive assessment for 2015 compensation for our Section 16 officers.

We discuss our processes and procedures for consideration and determination of compensation of our Section 16 officers in the Compensation Discussion and Analysis. We also discuss in the Compensation Discussion and Analysis the role of our executive officers in determining or recommending compensation for our Section 16 officers.

During 2014, the compensation committee retained Towers Watson to prepare the 2015 competitive assessment covering our Section 16 officers. In an engagement letter dated April 7, 2014, the compensation committee asked Towers Watson to prepare separate executive compensation reviews for the Section 16 officers and the chief executive officer. In its review for the Section 16 officers, excluding the chief executive officer, Towers Watson was asked to:


•	match the Section 16 officer positions to survey data to generate 2015 market estimates for base salaries and short-term and long-term incentives


•	address general trends in executive compensation


•	compare base salaries and target short-term and long-term incentives, by position, to market estimates and recommend salary grade changes as appropriate


•	construct a recommended 2015 salary grade structure and


•	verify the competitiveness of short-term and long-term incentive targets associated with salary grades and recommended modifications as appropriate.

58 MDU Resources Group, Inc. Proxy Statement

Proxy Statement

In the chief executive officer review, Towers Watson was asked to use survey data and data from the company’s performance graph peer group to:


•	develop competitive estimates for base salary and target short-term and long-term incentives


•	recommend changes in base salary and incentive targets based on competitive data and


•	address general trends in chief executive officer compensation.

The compensation committee has sole authority to retain or obtain the advice of 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 any adviser retained by the committee. Prior to retaining an adviser and annually, the committee will consider all factors relevant to the adviser’s independence from management. The compensation committee charter requires the committee’s pre-approval of the engagement of the committee’s compensation consultants by the company for any other purpose. The compensation committee authorized the company to participate in compensation and employee benefits surveys sponsored by Towers Watson in 2014.

Annually the compensation committee conducts an assessment of any potential conflicts of interest raised by the work of any compensation consultant to determine if any conflict exists and how such conflict should be addressed. The compensation committee requested and received information from its compensation consultant, Towers Watson, to assist the committee in determining whether Towers Watson’s work raised any conflict of interest. The compensation committee has reviewed Towers Watson’s responses to its request and determined that the work of Towers Watson did not raise any conflict of interest in 2014.

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. The compensation committee did not retain an outside consultant for the 2014 compensation review for the board of directors. At its May 2014 meeting, the committee reviewed the analysis of competitive data and recent trends in director compensation, including independent chairman of the board compensation, prepared by the human resources department and the vice president-human resources. The company’s analysis was based on proxy data from our performance graph peer group companies compiled by Equilar and on data from the National Association of Corporate Directors 2013/2014 Director Compensation Report (NACD Report). The committee compared the data to our directors’ compensation and each of its components. The market data indicated that our median director compensation of $165,000 was below the median total direct compensation of $196,026 for large companies with revenues between $2.5 billion and $10 billion in the NACD Report and below the median total direct compensation of $170,000 of the peer companies. With respect to non-executive chairman of the board compensation, the company’s total compensation of $255,000 was below the NACD Report large company median of $288,000 and below the median of $305,000 for nine peer group companies that had a non-executive chairman.

In light of the competitive analysis, after review and discussion, the compensation committee recommended, and the board approved, increasing the annual base retainer from $55,000 to $65,000 effective June 1, 2014 for all non-employee directors, including the non-executive chairman of the board.

Stockholder Communications

Stockholders and other interested parties who wish to contact the board of directors or an individual director, including our non-employee chairman 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.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16 of the Securities Exchange Act of 1934, as amended, requires that officers, directors, and holders of more than 10% of our common stock file reports of their trading in our equity securities with the Securities and Exchange Commission. Based solely on a review of Forms 3, 4, and 5 and any amendments to these forms furnished to us during and with respect to 2014 or written representations that no Forms 5 were required, we believe that all such reports were timely filed.

CONDUCT OF MEETING; ADJOURNMENT

The chairman of the board has broad responsibility and authority to conduct the annual meeting in an orderly and timely manner. In addition, our bylaws provide that the meeting may be adjourned from time to time by the chairman of the meeting regardless of whether a quorum is present.

OTHER BUSINESS

Neither the board of directors nor management intends to bring before the meeting any business other than the matters referred to in the notice of annual meeting and this proxy statement. We have not been informed that any other matter will be presented at the meeting by others. However, if any other matters are properly brought before the annual meeting, or any adjournment(s) thereof, your proxies include discretionary authority for the persons named in the enclosed proxy to vote or act on such matters in their discretion.

SHARED ADDRESS STOCKHOLDERS

In accordance with a notice sent to eligible stockholders who share a single address, we are sending only one annual report to stockholders and one proxy statement to that address unless we received instructions to the contrary from any stockholder at that address. This practice, known as “householding,” is designed to reduce our printing and postage costs. However, if a stockholder of record wishes to receive a separate annual report to stockholders and proxy statement in the future, he or she may contact the office of the treasurer at MDU Resources Group, Inc., P.O. Box 5650, Bismarck, ND 58506-5650, Telephone Number: (701) 530-1000.

Stockholders who own shares through a bank, broker, or other nominee can request householding by contacting the nominee.

We hereby undertake to deliver promptly, upon written or oral request, a separate copy of the annual report to stockholders and proxy statement to a stockholder at a shared address to which a single copy of the document was delivered.
