We were pleased with the stockholder response for the 2012 Annual Meeting at which 89.72 percent of the common stock was represented in person or by proxy. We hope for an even greater representation at the 2013 meeting.

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.

Brokers may not vote your shares on two of the three matters to be presented 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.

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 February 25, 2013, to the annual meeting, and (3) present their admission ticket(s) and photo identification, such as a driver’s license.

Proxy Statement




Proxy Statement

P ROXY STATEMENT

The board of directors of MDU Resources Group, Inc. is furnishing this proxy statement beginning March 13, 2013, to solicit your proxy for use at our annual meeting of stockholders on April 23, 2013, 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 $7,000 plus out-of-pocket expenses. We will pay the cost of soliciting your proxy and reimburse brokers and others for forwarding proxy material 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 2013, 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.

V OTING INFORMATION

Who may vote? You may vote if you owned shares of our common stock at the close of business on February 25, 2013. 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 February 25, 2013, we had 188,830,529 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 auditors for 2013

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 that matter 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.

MDU Resources Group, Inc. Proxy Statement

Proxy Statement


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.

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 Auditors for 2013
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-votes are not counted as voting power present 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? There are three ways to vote by proxy:

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

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

by returning the enclosed proxy card in the envelope provided.

You may be able to vote by telephone or the Internet if your shares are held in the name of a bank or broker. 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 the holder of record of the shares, usually 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 revoke my proxy? Yes.

If you are a stockholder of record, you can revoke your proxy by:

filing written revocation with the corporate secretary before the meeting

filing a proxy bearing a later date with the corporate secretary before the meeting or

revoking your proxy at the meeting and voting in person.

Nominating and Governance Committee

Ms. Moss served as the president and chief executive officer of Cascade Bancorp, a financial holding company in Bend, Oregon, from 1998 to January 3, 2012. She served as the chief executive officer of Cascade Bancorp’s principal subsidiary, Bank of the Cascades, from 1993 to January 3, 2012, serving also as president from 1993 to 2003. From 1987 to 1998, Ms. Moss served as chief operating officer, chief financial officer, and corporate secretary of Cascade Bancorp. Ms. Moss has been a director of Cascade Bancorp since 1993 and a director of Bank of the Cascades since 1998 and was elected vice chairman of both boards effective January 3, 2012. Ms. Moss also serves as a director of the Oregon Investment Fund Advisory Council, a state-sponsored program to encourage the growth of small businesses within Oregon, co-chairs the Oregon Growth Board, a state agency created to provide recommendations to connect businesses to sources of capital, and serves on the City of Bend’s Juniper Ridge management advisory board.

Ms. Moss graduated magna cum laude with a bachelor of science degree in business administration from Linfield College in Oregon and did master’s studies at Portland State University. She received commercial banking school certification at the ABA Commercial Banking School at the University of Oklahoma. She served as a director of the Oregon Business Council, whose mission is to mobilize business leaders to contribute to Oregon’s quality of life and economic prosperity; the Cascades Campus Advisory Board of the Oregon State University; the North Pacific Group, Inc., a wholesale distributor of building materials, industrial and hardwood products, and other specialty products; the Aquila Tax Free Trust of Oregon, a mutual fund created especially for the benefit of Oregon residents; Clear Choice Health Plans Inc., a multi-state insurance company; and as a director and chair of the St. Charles Medical Center.

In August 2009, the Federal Deposit Insurance Corporation and the Oregon Division of Finance and Corporate Securities entered into a consent agreement with Bank of the Cascades that requires the bank to develop and adopt a plan to maintain the capital necessary for it to be “well-capitalized,” to improve its lending policies and its allowance for loan losses, to increase its liquidity, to retain qualified management, and to increase the participation of its board of directors in the affairs of the bank. In October 2009, the bank’s parent, Cascade Bancorp, entered into a written agreement with the Federal Reserve Bank of San Francisco and the Oregon Division relating largely to improving the financial condition of Cascade Bancorp and the Bank of the Cascades. Cascade Bancorp reported in its third quarter 2012 Form 10-Q that at December 31, 2011, Cascade Bancorp and the Bank did not meet the written agreement’s leverage ratio requirement and as a result they had filed a required update to their capital plan, which was accepted by their regulators. On September 30, 2012, Bancorp and the Bank had met this requirement. The order remains in place until lifted by the regulators.

The board concluded that Ms. Moss 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. A significant portion of MDU Resources Group, Inc.’s utility, construction services, and contracting operations are located in the Pacific Northwest. Ms. Moss has first-hand business experience and knowledge of the Pacific Northwest economy and local, state, and regional issues through her executive positions at Cascade Bancorp and Bank of the Cascades, where she gained over 30 years of experience. Ms. Moss provides to our board her experience in finance and banking, as well as her experience in business development through her work at Cascade Bancorp and on the Oregon Investment Advisory Council, the Oregon Business Council, and the Oregon Growth Board. This business experience demonstrates her leadership abilities and success in the finance and banking industry. Ms. Moss is also certified as a Senior Professional in Human Resources, which makes her well-suited for our compensation committee. In deciding that Ms. Moss should be renominated as a director, the board was mindful of the consent agreement with Bank of the Cascades, but concluded that Ms. Moss brought the many skills and experiences discussed above to our board and had proved herself to be a dedicated and hard-working director.

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 electric and natural gas utility business was our core business when our company was founded in 1924. That business now operates through four utilities: Montana-Dakota Utilities Co., Great Plains Natural Gas Co., Cascade Natural Gas Corporation, and Intermountain Gas Company. Mr. Wilson is our only non-employee director with direct experience in this area through his prior positions at Great Plains Natural Gas Co. and Great Plains Energy Corp. In addition, Mr. Wilson’s extensive finance and accounting experience make him well-suited for our audit committee.

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.

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

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

acceptance of such resignation by the board of directors.

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

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

I TEM 2. RATIFICATION OF INDEPENDENT AUDITORS

The audit committee at its February 2013 meeting appointed Deloitte & Touche LLP as our independent auditors for fiscal year 2013. The board of directors concurred with the audit committee’s decision. Deloitte & Touche LLP has served as our independent auditors since fiscal year 2002.

Although your ratification vote will not affect the appointment or retention of Deloitte & Touche LLP for 2013, the audit committee will consider your vote in determining its appointment of our independent auditors for the next fiscal year. The audit committee, in appointing our independent auditors, 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 auditors for 2013.

Ratification of the appointment of Deloitte & Touche LLP as our independent auditors for 2013 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.

Pre-Approval Policy
The audit committee pre-approved all services Deloitte & Touche LLP performed in 2012 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 as an exhibit thereto or may be delivered in a separate written statement.

I TEM 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:

Proxy Statement

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-votes are not counted as voting power present and, therefore, are not counted in the vote.

Use of Non-GAAP Financial Measures
As noted above, the company, in addition to presenting its earnings information in conformity with Generally Accepted Accounting Principles (GAAP), has provided non-GAAP earnings data that reflects an adjustment to exclude a fourth quarter 2012 $145.9 million after-tax noncash ceiling test write-down, a third quarter 2012 $100.9 million after-tax noncash ceiling test write-down, as well as an adjustment to exclude a second quarter 2012 reversal of an arbitration charge of $15.0 million after-tax. The company believes that these non-GAAP financial measures are useful to investors because the items excluded are not indicative of the company’s continuing operating results. Also, the company’s management uses these non-GAAP financial measures as indicators for planning and forecasting future periods. The presentation of this additional information is not meant to be considered a substitute for financial measures prepared in accordance with GAAP.

Total Realized Pay in 2012 and 2011
The compensation committee believes considering total realized pay is equally as important as considering 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. Also, the summary compensation table shows an increase in change in pension value and above-market earnings on nonqualified deferred compensation. The pension plan was frozen as of December 31, 2009, and none of the named executives’ benefit levels in the Supplemental Income Security Plan, our non-qualified retirement program, increased for 2012. The primary reason for increases in the change in pension value is due to a lower discount rate used to calculate the values.

Total realized pay, on the other hand, reflects the compensation actually earned, including the value of incentive awards if the goals are met and excluding the value of incentive awards if the goals are not met. Because we have not met certain performance measures in the last several years, our named executive officers’ total realized pay excludes the value of incentive awards that were not earned. We define total realized pay as the sum of base salary, annual incentive award paid, the value realized upon the vesting of long-term incentive awards of performance shares, and all other compensation as reported in the summary compensation table.

Mr. Wells was hired as president and chief executive officer of Fidelity Exploration & Production Company effective May 2, 2011. Includes a cash recruitment payment of $550,000, annual incentive payment of $448,981, and additional annual incentive payment of $925,010.

Our named executive officers forfeited all performance shares and dividend equivalents for the 2009-2011 performance period because our total stockholder return in comparison to our peer group was at the 25th percentile. With respect to the annual incentive awards, our 2012 results in the construction services segment, construction materials and contracting segment, and the pipeline and energy services segment were above their performance targets, and, conversely, 2012 results for the exploration and production segment and the electric and gas distribution segments were below their threshold performance goals, with 2012 consolidated earnings per share results also below threshold. Since the corporate named executives’ annual incentives depend on achievement of the foregoing performance goals, Messrs. Hildestad’s, Schwartz’s, and Schneider’s 2012 annual incentives were paid below the target amount.

With respect to our chief executive officer, the following table further demonstrates our pay for performance approach by comparing:

Overview of 2012 Compensation for our Named Executive Officers
In 2012, we continued our approach of referencing market data to establish competitive pay levels for base salary, total annual cash, which is base salary plus target annual incentive, and total direct compensation, which is the sum of total annual cash plus the expected value of target long-term incentives. We discuss this competitive assessment in the Role of Management section below. To ensure compensation awarded to named executive officers was commensurate with competitive performance levels, we continued to compare:

total stockholder return results to the results of our performance graph peer group to determine payouts under our performance share program and

on a historical basis, our targeted and actual results on return on invested capital to the results of our performance graph peer group when the compensation committee established performance targets for annual incentives of our business segment leaders.

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

we pay for performance, with 55.6% to 76.5% of our named executive officers’ 2012 total target direct compensation in the form of incentives

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

we determine long-term performance incentives based on total stockholder return relative 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 and

through our PEER Analysis, we compare our pay-for-performance results on key financial metrics – revenue, profit, return on invested capital, and stockholder return – in comparison to our performance graph peer group.

The compensation committee took the following actions with respect to 2012 compensation for our named executive officers:

granted a salary increase to Mr. Hildestad to recognize his effective leadership during an extended period of economic softness. Mr. Hildestad subsequently rejected the salary increase because he felt accepting the increase would be out of place since five of the thirteen Section 16 officers did not receive an increase for 2012

granted a salary increase to Mr. Schwartz to bring his salary closer to his salary grade midpoint


MDU Resources Group, Inc. Proxy Statement

Proxy Statement


tied 25% of our business segment leaders’ 2012 annual incentive targets to the company’s 2012 earnings per share results in order to more closely align amounts paid to these executives with total company results

increased Mr. Wells’ annual incentive target from 100% to 125% of base salary to mitigate the impact of the added company earnings per share goal and to reflect his impact on overall company results

continued to link our corporate executives’ – i.e., Messrs. Hildestad, Schwartz, and Schneider – 2012 annual incentive awards to the achievement of our business segments’ performance goals

did not approve payment of any performance shares or dividend equivalents granted in 2009 for the 2009-2011 performance period due to our total stockholder return for the 2009-2011 performance period placing us in the 25th percentile compared to our performance graph peer group and

granted no increases under our Supplemental Income Security Plan, which is a nonqualified retirement plan that provides benefits to our key managers and four of our named executive officers.

In addition, our Section 16 officers who had change of control employment agreements agreed to the early termination of their agreements, effective November 1, 2012.

Objectives of our Compensation Program

We structure our compensation program to help retain and reward the executive officers who we believe are critical to our long-term success. 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

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.

Elements of our Compensation Program

We pay/grant:

base salaries in order to provide executive officers with sufficient, regularly-paid income and attract, recruit, and retain executives with the knowledge, skills, and abilities necessary to successfully execute their job duties and responsibilities

opportunities to earn annual incentive compensation in order to be competitive from a total remuneration standpoint and ensure focus on annual financial and operating results and

opportunities to earn long-term incentive compensation in order to be competitive from a total remuneration standpoint and ensure focus on stockholder return.

If earned, incentive compensation, which consists of annual cash incentive awards and three-year performance share awards under our Long-Term Performance-Based Incentive Plan, makes up the greatest portion of our named executive officers’ total compensation. The compensation committee believes incentive compensation that comprised approximately 55.6% to 76.5% of total target compensation for the named executive officers is appropriate 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 majority of the named executive officers’ target compensation contingent upon results that are beneficial to stockholders.

The following table shows the allocation of total target compensation for 2012 among the individual components of base salary, annual incentive, and long-term incentive:

J. Kent Wells 23.5 29.4 47.1 76.5
William E. Schneider 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. 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, 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 consistently deliver financial results that build wealth for all stockholders over the long-term.

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 2010 for use by the compensation committee to determine 2011 compensation levels. In 2011, the compensation committee requested the competitive assessment be completed internally. They directed the vice president-human resources and the human resources department to prepare the competitive assessment in August 2011 on Section 16 officers for their use in establishing 2012 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 target 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% annualized to estimate the 2012 competitive targets.

The compensation surveys are listed on the following table:

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 68 additional chief executive officers from public companies in the energy, construction, and utility 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 55 additional chief financial officers from public companies in the energy, construction, and utility industries with revenues ranging from $1 billion to $8 billion.

For the president and chief executive officer of our exploration and production segment, the Equilar companies included the exploration and production companies in our performance graph peer group and data on 27 additional chief executive officers from public companies in the oil and gas exploration and production industries with revenues ranging from $250 million to $850 million.

For the president and chief executive officer of the pipeline and energy services segment, the Equilar companies included the pipeline and energy services companies in our performance graph peer group and data on 13 chief executive officers from public companies in the pipeline and energy services industry with revenues of $1 billion or less.

The chief executive officer played an important role in recommending 2012 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 2012 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.

Timing of Compensation Decisions for 2012

The compensation committee, in conjunction with the board of directors, determined all compensation for each named executive officer for 2012 and set overall and individual compensation targets for the three components of compensation – base salary, annual incentive, and long-term incentive. 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 and established 2012 salary grades at its August 2011 meeting. At the November 2011 meeting, it established individual base salaries, target annual incentive award levels, and target long-term incentive award levels for 2012. At their February and March 2012 meetings, the compensation committee and the board of directors increased the target annual incentive award level for Mr. Wells and determined annual and long-term incentive awards, along with the payouts based on performance from the recently completed performance period for prior annual and long-term awards. The February and March 2012 meetings occurred after the release of earnings for the prior year.

Stockholder Advisory Vote (“Say on Pay”)

Our stockholders had their second advisory vote on our named executive officers’ compensation at the 2012 Annual Meeting of Stockholders. Approximately 92% of the shares present in person or represented by proxy and entitled to vote on the matter approved the named executive officers’ compensation. The 92% approval is consistent with the results of our say on pay vote at the 2011 Annual Meeting. The compensation committee and the board of directors considered the results of the votes at their November 2011 and November 2012 meetings and did not change our executive compensation program as a result of the votes.

Salary Grades for 2012

The compensation committee determines the named executive officers’ base salaries and annual and long-term incentive targets 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 annual and long-term incentive target 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

Proxy Statement

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. Mr. Wells’ 2011 compensation was determined pursuant to his letter agreement in connection with his hiring effective May 2, 2011, and served as a basis for his 2012 compensation, rather than the business segment leaders’ salary grade.

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.

No changes were made in the salary grade classifications of the named executive officers for 2012, and after reviewing the competitive analysis, the compensation committee made no changes in the base salary ranges associated with each named executive officer’s salary grade classification.

Our named executive officers’ salary grade classifications for 2012 are listed below, along with the base salary ranges associated with each classification:

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:


visionary leadership

leadership

strategic thinking

mentoring

leading with integrity

relationship building

managing customer focus

conflict resolution

financial responsibility

organizational savvy

achievement focus

safety

judgment

risk management

planning and organization

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.

The chief executive officer assessed each other named executive officer’s performance under the performance assessment program, and the compensation committee, as well as the full board of directors, assessed the chief executive officer’s performance.

Base Salaries of the Named Executive Officers for 2012

Terry D. Hildestad

The compensation committee recommended a 6.67% salary increase for Mr. Hildestad for 2012, which would have raised his salary from $750,000 to $800,000 ($775,000 being the market median). The compensation committee’s rationale for the increase was


his high performance evaluation

his high integrity, excellent business know how, and ability to work effectively with the management team and the board

his effectiveness in navigating the company through a difficult economic environment and

his salary had been frozen since January 1, 2009.

Mr. Hildestad, however, did not accept his base salary increase for 2012 in order to be treated the same as other Section 16 officers who did not receive a salary increase for 2012.

Doran N. Schwartz

Mr. Schwartz was elected vice president and chief financial officer effective February 17, 2010. For 2012, the compensation committee awarded Mr. Schwartz a 9.9% increase, raising his 2012 salary from $273,000 to $300,000, or 92% of the midpoint of salary grade I for 2012. The compensation committee’s rationale for the increase was in recognition of:


his assistance in the company achieving a return on invested capital of 6.9% for the twelve months ending June 2011 as compared to the median return on invested capital of 6.0% for companies in our performance graph peer group over the same time period

his success at building good working relationships with shareholders, rating agencies, and the financial community and

moving his salary closer to the midpoint of salary grade I.


Steven L. Bietz

Mr. Bietz received no salary increase for 2012 because the compensation committee wanted to limit salary cost increases.

J. Kent Wells

Mr. Wells received no salary increase for 2012 because he had just started his employment with the company in May 2011 with a salary above the maximum for his salary grade.

William E. Schneider

Mr. Schneider received no salary increase for 2012 because his salary was 115% of the market value for his position and the compensation committee wanted to limit salary cost increases.

2012 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. For all business segment chief executive officers, including Messrs. Wel l s and Bietz, the performance measures for annual incentive awards are

their respective business segment’s annual return on invested capital results compared to target

their respective business segment’s allocated earnings per share results compared to target and

the company’s consolidated earnings per share compared to a target of $1.19.

The compensation committee added the third performance measure, consolidated earnings per share, for the first time in 2012. The compensation committee weighted the 2012 performance measures for Messrs. Wells and Bietz at 75% for their business segment performance measures (weighted evenly) and 25% for the company’s earnings per share measure to more closely tie their annual incentive amounts to total company results.

For the named executive officers working at MDU Resources Group, Inc. in 2012, who were Messrs. Hildestad, Schwartz, and Schneider, the compensation committee based 2012 annual incentives on the achievement of performance goals at the business segments: (i) the construction materials and contracting and construction services segments, (ii) the pipeline and energy services segment, (iii) the exploration and production segment, and (iv) 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.

The compensation committee believes 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. Earnings per share is a generally accepted accounting principle measurement and is a key driver of stockholder return over the long-term. Return on invested capital measure show efficiently and effectively management deploys capital. Sustained returns on invested capital in excess of a business segment’s cost of capital create value for our stockholders.

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.

We establish our incentive plan performance 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. In determining where to set the return on invested capital target, the compensation committee 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 2012, the compensation committee chose to use the return on invested capital target for each business segment as approved by the board in the 2012 business plan, except for the construction services segment, which had a target higher than the 2012 business plan to incentivize efforts for that segment to achieve its weighted average cost of capital within five years. The compensation committee imposed an additional requirement for the 2012 return on invested capital portion of the annual incentives for the construction materials and contracting segment, the construction services segment, and the exploration and production segment. The additional requirement was the business segment needed to achieve its weighted average cost of capital in order to achieve 200% of the annual incentive target attributable to the return on invested capital portion of the annual incentive. However, payments with respect to 2012 return on invested capital results above the 2012 target but below the weighted average cost of capital would be interpolated, in order to motivate these executives to achieve performance levels between the return on invested capital performance targets and the weighted average cost of capital for their respective business segments.

Named Executive Officers’ 2012 Incentive Targets and Why We Chose Them

Targets
The compensation committee established the named executive officers’ annual incentive targets as a percentage of each officer’s actual 2012 base salary.

Messrs. Hildestad’s, Schwartz‘s, and Schneider’s 2012 target annual incentives were 100%, 50%, and 65% of base salary, respectively. The compensation committee determined the 2012 annual incentive targets would remain unchanged from 2011 for these named executives based on the following reasons:

For Mr. Hildestad, the annual incentive target of 100% of base salary was slightly above the 86% of base salary paid to chief executive officer positions based on salary survey data from the competitive assessment. The committee believed this difference was too small to warrant a change in Mr. Hildestad’s 2012 incentive target.

For Mr. Schwartz, the annual incentive target of 50% of base salary was slightly below 57% of base salary paid to chief financial officers based on salary survey data from the competitive assessment. The committee believed this difference was too small to warrant a change in Mr. Schwartz’s 2012 incentive target.

For Mr. Schneider, the compensation committee determined his 2012 incentive target should remain the same from 2011 because of the importance the company placed on his new role of leveraging opportunities in the Bakken that would cut across all of the company’s business segments. There was no competitive data compiled on his position.

Mr. Bietz’s 2012 target annual incentive was 65% of base salary. The compensation committee determined the 2012 annual incentive target would remain unchanged from 2011 for Mr. Bietz because the annual incentive based on salary survey data from the competitive assessment was 62% of base salary. The committee believed this difference was too small to warrant a change in Mr. Bietz’s 2012 target annual incentive.

Mr. Wells’ 2012 incentive target was 125% of bases salary, which was increased from 100% of base salary. The committee raised Mr. Wells’ annual incentive target to mitigate the impact of the added company earnings per share goal and to reflect his business segment’s impact on overall company results. The committee recognized the significant investment that his business segment will make and the desire to incentivize and motivate Mr. Wells to generate earnings that can greatly impact overall company earnings.

Named Executive Officers’ 2012 Incentive Payments

Terry D. Hildestad, Doran N. Schwartz, and William E. Schneider
As discussed above, Messrs. Hildestad, Schwartz, and Schneider were awarded 2012 incentives based on achievement of performance goals at the business segments. The award opportunities and results for the business segments are discussed below.

As a result of the performance goals achieved at the business segments, Messrs. Hildestad, Schwartz, and Schneider earned 69.1% of their target awards, resulting in a payment of $518,250 for Mr. Hildestad, $103,650 for Mr. Schwartz, and $200,950 for Mr. Schneider.

Pipeline and Energy Services Segment
For the pipeline and energy services segment, the 2012 award opportunity was comprised of three components:

The pipeline and energy services segment component represented 75% of the target award, and payout could range from no payment if the results were below the 85% level to a 200% payout if:

o

the 2012 allocated earnings per share for the segment were at or above the 115% level and

o

the 2012 return on invested capital was at or above the 115% level.

The MDU Resources Group, Inc. earnings per share component represented 25% of the award and payout could range from no payment if the results were below the $1.19 to a 200% payout if the results were $1.37 or higher.

The pipeline and energy services segment 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:

o

each established local safety committee will conduct eight meetings per year

o

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

o

report vehicle accidents and personal injuries by the end of the next business day

o

achieve the targeted vehicle accident incident rate of 2.25 or less and

o

achieve the targeted personal injury incident rate of 2.0 or less.

MDU Resources Group, Inc. Proxy Statement



Proxy Statement

The committee set the pipeline and energy services segment’s 2012 allocated earnings per share and return on invested capital below the 2011 target levels and below the 2011 actual results. The 2012 target levels were based on lower natural gas prices and, as a result, lower storage and gas transmission activity.

The committee set the MDU Resources Group, Inc. earnings per share target at $1.19 because it was equal to the 2011 result, and the committee believed tying 25% of the incentive award to delivering at least $1.19 in 2012 was appropriate.

The pipeline and energy services segment’s 2012 earnings per share and return on invested capital were 179.8% and 143.1% of their respective 2012 targets, equating to 200% of the target amount attributable to that component. Also, MDU Resources Group, Inc.’s 2012 earnings per share results were $(.01), equating to 0% of the target amount attributable to that component.

Results at the pipeline and energy services segment (before adjustment for the five safety goals) were 150% of the 2012 target annual incentive. One of the five safety goals was not met because WBI Energy’s personal injury incident rate was 2.67. Therefore, the incentive results were reduced from 150% to 148.5% of the 2012 target annual incentive.

Exploration and Production Segment
For the exploration and production segment, the 2012 award opportunity was comprised of two components:

The exploration and production business segment component represented 75% of the target award, and payout could range from no payment if the results were below the 85% level to a 200% payout if:

o

the 2012 allocated earnings per share for the segment were at or above the 115% level and

o

the 2012 return on invested capital was at least equal to the segment’s 2012 weighted average cost of capital.

The MDU Resources Group, Inc. earnings per share component represented 25% of the award and payout could range from no payment if the results were below the $1.19 target to a 200% payout if the results were $1.37 or higher.

The committee set the exploration and production segment’s 2012 allocated earnings per share and return on invested capital target levels below the 2011 actual results. The 2012 al l ocated earnings per share target level was above the 2011 target level, and the 2012 return on invested capital target level was below the 2011 target level. The 2012 target levels were based on lower natural gas prices and higher depletion, depreciation, and amortization amounts. The committee set the MDU Resources Group, Inc. earnings per share target at $1.19 because it was equal to the 2011 result, and the committee believed tying 25% of the incentive award to delivering at least $1.19 in 2012 was appropriate.

This segment’s 2012 earnings per share and return on invested capital were negative equating to no payment on either component. Also, MDU Resources Group, Inc.’s 2012 earnings per share results were $(.01), equating to 0% of the target amount attributable to that component.

Overall results for 2012 were 0%.

Construction Services and Construction Materials and Contracting Segments
For purposes of determining the annual incentive awards of the MDU Resources Group, Inc. executives and the chief executive officer of these segments, these segments were combined. The 2012 award opportunity was comprised of three components:

The construction services segment component represented 37.5% of the target award, and payout could range from no payment if the results were below the 85% level to a 200% payout if:

o

the 2012 allocated earnings per share for the segment were at or above the 115% level and

o

the 2012 return on invested capital was at least equal to the segment’s 2012 weighted average cost of capital.

The construction materials and contracting segment component represented 37.5% of the award, and payment could range from no payment if the results were below the 85% level to a 200% payout if:

o

the 2012 allocated earnings per share for the segment were at or above the 115% level and

o

the 2012 return on invested capital was at least equal to the segment’s 2012 weighted average cost of capital.

The MDU Resources Group, Inc. earnings per share component represented 25% of the award and payout could range from no payment if the results were below the $1.19 target to a 200% payout if the results were $1.37 or higher.

Proxy Statement

The committee set the construction services business segment’s 2012 allocated earnings per share and return on invested capital target levels above the 2011 target levels and below the 2011 actual results. The construction materials and contracting business segment’s 2012 allocated earnings per share target level was set below the 2011 target level and 2011 actual results, and the 2012 return on invested capital target level was set above the 2011 target level and equal to the 2011 actual results. The 2012 target levels reflected significant uncertainty in the overall construction market, including an absence of a federal highway bill and continued low margins due to competitive bids on construction projects. The committee set the MDU Resources Group, Inc. earnings per share target at $1.19 because it was equal to the 2011 result, and the committee believed tying 25% of the incentive award to delivering at least $1.19 in 2012 was appropriate.

The construction services segment’s 2012 earnings per share and return on invested capital were 226.6% and 205.4% of their respective 2012 targets, equating to 200% of the target amount attributable to that component. The construction materials and contracting segment’s 2012 earnings per share and return on invested capital were 158.1% and 117.1% of their respective 2012 targets, equating to 155.9% of the target amount attributable to that component. MDU Resources Group, Inc.’s 2012 earnings per share results were $(.01), equating to 0% of the target amount attributable to that component.

Overall results for 2012 were 133.5% of the 2012 target annual incentive award.

Electric and Natural Gas Distribution Segments
For the electric and natural gas distribution segments, the 2012 award opportunity was comprised of two components:

the electric and natural gas distribution business segments component represented 75% of the target award, and payout could range from no payment if the allocated earnings per share and return on invested capital results were below the 85% level to a 200% payout if:

o

the 2012 allocated earnings per share for the segment were at or above the 115% level and

o

the 2012 return on invested capital was at or above the 115% level.

The MDU Resources Group, Inc. earnings per share component represented 25% of the award and payout could range from no payment if the results were below the $1.19 target to a 200% payout if the results were $1.37 or higher.

The committee set the 2012 target for allocated earnings per share higher than the 2011 targets but lower than 2011 actual results to reflect a one-time income tax benefit in 2011. The committee set the 2012 return on invested capital target at the 2011 target level, which was below 2011 actual results to reflect a one-time income tax benefit in 2011. For 2012, the electric and natural gas distribution segments’ 2012 earnings per share and return on invested capital were 93.1% and 93.6% of their respective targets, equating to 66.7% of the target amount attributable to that component. MDU Resources Group, Inc.’s 2012 earnings per share results were $(.01), equating to 0% of the target amount attributable to that component.

Overall results for these segments were 50% of the 2012 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 2012, 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 “BBB” 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 5.46%. 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.

2012 Long-Term Incentives

Awards Granted in 2012 under the Long-Term Performance-Based Incentive Plan for Named Executives
We use the Long-Term Performance-Based Incentive Plan, which has been approved by our stockholders, for long-term incentive compensation. We use 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 used the performance graph peer group as the comparator group to determine relative stockholder return and potential payments for the 2012 performance share awards. The performance graph peer group consisted of the following companies when the committee granted performance shares in February 2012:

Alliant Energy Corporation

Martin Marietta Materials, Inc.

Southwest Gas Corporation

Atmos Energy

National Fuel Gas Company

Sterling Construction Company

Berry Petroleum Company

MDU Resources Group, Inc. Proxy Statement

Proxy Statement

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.

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 annual incentive target, we determined the long-term incentive target 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. From an internal equity standpoint, the committee believed positions in the same salary grade should have the same long-term incentive target level. From an internal equity standpoint, the committee believed in keeping the chief executive officer’s long-term incentive target below a level indicated from the competitive assessment. Mr. Hildestad’s target was 150% of base salary, below the salary survey median of 231% of base salary for chief executive officers. The compensation committee has historically set Mr. Hildestad’s target long-term incentive compensation below the level indicated by the competitive assessment to offset his benefit under the Supplemental Income Security Plan, our nonqualified defined benefit plan, which prior assessments have shown to be higher than competitive levels. The 2012 long-term incentive targets as a percentage of base salary for Messrs. Schwartz, Bietz, and Schneider were unchanged from 2011 because the targets were in line with the competitive assessment’s targets. Mr. Wells’ long-term incentive target is 200% of base salary, which is higher than the 90% long-term incentive target for other executives in salary grade J. The higher target for Mr. Wells was pursuant to his letter agreement and reflects the committee’s judgment of offsetting Mr. Wells’ non-participation in our Supplemental Income Security Plan.

On February 16, 2012, 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 2012 base salary by his or her long-term incentive target and then dividing this product by the average of the closing prices of our stock from January 1, 2012 through January 22, 2012, as shown in the following table:

Assuming our three-year (2012 to 2014) total stockholder return is positive, from 0% to 200% of the target grant will be paid out in February 2015 depending on our total stockholder return compared to the total three-year stockholder returns of companies in our performance graph peer group.

No Payment in February 2012 for 2009 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 12, 2009 for the 2009 through 2011 performance period. Our total stockholder return for the 2009 through 2011 performance period was 9.25%, which corresponded to a percentile rank of 25% against our performance graph peer group and resulted in no shares or dividend equivalents being paid to the named executive officers.

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 2007 through 2011 by our average annual total stockholder return for the same five-year period to yield our pay ratio. 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.

For the five-year period of 2007 through 2011, our average annual stockholder return was minus .88%. Therefore, our pay ratio is not a meaningful statistic and a comparison to the pay ratio of the companies in the performance graph peer group could not be made. The compensation committee believes that the analysis continues to serve a useful purpose in its annual review of compensation despite the effect of the negative stockholder return for the 2007 through 2011 period.

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 each of the named executive officers, except Mr. Schwartz who is eligible for 10.5% and Mr. Wells who is eligible for 5%.

Supplemental Income Security Plan
Benefits Offered
We offer certain key managers and executives, including all of our named executive officers, except Mr. Wells, 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 critical 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.

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 officer did not recommend a 2012 SISP benefit level increase for any of the named executive officers, and the committee chose not to grant a 2012 SISP benefit level increase to the chief executive officer. The following table reflects our named executive officers’ SISP levels as of December 31, 2012:

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.

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 2012 satisfied the requirements for deductibility, except for $48,129 paid to Mr. Wells.

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 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.

MDU Resources Group, Inc. Proxy Statement




Proxy Statement

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, 2012:

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 2012 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.

C ompensation 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.

Incentive Awards

Annual Incentive
On March 1, 2012, the compensation committee recommended the 2012 annual incentive award opportunities for our named executive officers and the board approved these opportunities at its meeting on March 1, 2012. These award opportunities are reflected in the Grants of Plan-Based Awards table at grant on March 1, 2012, in columns (c), (d), and (e) and in the Summary Compensation Table as earned with respect to 2012 in column (g).

MDU Resources Group, Inc. Proxy Statement

Proxy Statement

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. Actual payment may range from 0% to 200% of the target based upon achievement of goals.

In order to be eligible to receive a payment of an annual incentive award under the Long-Term Performance-Based Incentive Plan, Messrs. Hildestad, Bietz, Wells, and Schneider must have remained employed by the company through December 31, 2012, unless the compensation 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, including but not limited to the 20% limitation described in the following sentence. The 20% limitation means that no more than 20% of after-tax earnings that are in excess of planned earnings at the business segment level for operating company executives and at the MDU Resources Group level for corporate executives will be paid in annual incentives to executives. The application of this limitation or any other 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 Mr. Schwartz, participants who retire at age 65 during the year 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 award payments for Messrs. Hildestad, Schwartz, and Schneider were determined based on achievement of performance goals at the following business segments – (i) construction services and construction materials and contracting, (ii) exploration and production, (iii) pipeline and energy services, and (iv) electric and natural gas distribution - and were calculated as follows:

On February 14, 2012, the compensation committee recommended long-term incentive grants to the named executive officers in the form of performance shares, and the board approved these grants at its meeting on February 16, 2012. 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 2012-2014 total shareholder return is positive, from 0% to 200% of the target grant will be paid out in February 2015, depending on our 2012-2014 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

February 16, 2012 Grant

%

70th

150

%

50th

100

%

40th

10

%

Less than 40th

%

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 2015 at the same time as the performance awards are paid.

If the common stock of a company in the peer group ceases to be traded at any time during the 2012-2014 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.

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, 2012, 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)

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 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 pension plans absent Internal Revenue Code limitations.

(5)

Mr. Wells is not eligible to participate in our pension plan and does 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, 2012, calculated using a 3.45%, 3.59%, 3.76%, and 3.58% discount rate for the SISP excess, MDU pension plan, WBI pension plan, and KR pension plan, respectively, the 2013 IRS Static Mortality Table for post-retirement mortality, and no recognition of future salary increases or pre-retirement mortality. The assumed retirement ages for these benefits was age 60 for Messrs. Schwartz and Bietz. This is the earliest age at which the executives could begin receiving unreduced benefits. Retirement on December 31, 2012, was assumed for Messrs. Hildestad and Schneider, who were age 63 and 64, respectively, on that date. The amounts shown for the SISP I and SISP II were determined using a 3.45% discount rate and assume benefits commenced at age 65.

MDU Resources Group, Inc. Proxy Statement

Proxy Statement


Pension Plans

Messrs. Hildestad 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. Mr. Schneider participates in the Knife River Corporation Salaried Employees’ Pension Plan, which we refer to as the KR 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 KR pension plan uses the same formula except that 1.2% and 1.6% are used instead of 1.1% and 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.

Each of the pension plans was 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. Under the KR pension plan, participants must remain employed until age 62 or elect to defer commencement of benefits until age 62 to receive unreduced benefits. Mr. Hildestad was eligible for unreduced retirement benefits under the MDU pension plan, and Mr. Schneider was eligible for unreduced retirement benefits under the KR pension plan on December 31, 2012. 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 in the MDU pension plan and the WBI pension plan. 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. Bietz would have been eligible for a lump sum if he had retired on December 31, 2012.

The Internal Revenue Code limits the amounts that may be paid under the pension plans and the amount of compensation that may be 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 that could be recognized when determining benefits was $245,000.

Supplemental Income Security Plan

We also offer key managers and executives, including our named executive officers, except Mr. Wells, benefits under our nonqualified retirement plan, which we refer to as the Supplemental Income Security Plan or 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. None of the named executive officers have received a benefit level increase since the amended schedule became effective.

36

MDU Resources Group, Inc. Proxy Statement




Proxy Statement

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, 2012, 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.”

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.

MDU Resources Group, Inc. Proxy Statement

Proxy Statement

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. Schwartz are fully vested in their SISP benefits, this would not result in any incremental benefit for the named executive officers other than Mr. Schwartz. The present value of these two additional years of service for Mr. Schwartz is reflected in the table in “Potential Payments upon Termination or Change of Control” below.

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. Messrs. Hildestad, Bietz, and Schneider would be entitled to the SISP excess benefit if they were to terminate employment prior to age 65. Messrs. Schwartz and Wells 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.

Includes $392,000 which was reported in the Summary Compensation Table for 2006 in column (g) and $37,805 which is reported for 2010 in column (g) of the Summary Compensation Table in this proxy statement.

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 2012 was 5.46% 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 “BBB” 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.

38

MDU Resources Group, Inc. Proxy Statement




Proxy Statement

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.


P otential 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, 2012. 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 also do not include the named executive officers’ benefits under our nonqualified deferred compensation plans, which are reported in the Nonqualified Deferred Compensation for 2012 table. See the Pension Benefits for 2012 table and the Nonqualified Deferred Compensation for 2012 table, and accompanying narratives, for a description of the named executive officers’ accumulated benefits under our qualified defined benefit pension plans and our nonqualified deferred compensation plans.

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 2012 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, 2012 for Messrs. Hildestad, Bietz, and Schneider.

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. Hildestad, Schwartz, Bietz, Wells, and Schneider and the annual incentives for Messrs. Hildestad, Bietz, Wells, and Schneider, 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.

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 prorated 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 prorated 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, 2012, Messrs. Schwartz, Bietz, and Wells had not satisfied this requirement. Accordingly, if a December 31, 2012 termination other than for cause without a change of control is assumed, the named executive officers’ 2012-2014 performance share awards would be forfeited, any amounts earned under the 2011-2013 performance share awards for Messrs. Hildestad and Schneider would be reduced by one-third and such award for Messrs. Schwartz and Bietz would be forfeited, and any amounts earned under the 2010-2012 performance share awards for Messrs. Hildestad and Schneider would not be reduced and the award for Messrs. Schwartz and Bietz would be forfeited. Mr. Wells had no 2011-2013 or 2010-2012 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 2010-2012 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 2011-2013 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 2012-2014 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, 2012, 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, 2012.

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.

The annual stock grant is a grant of shares equal in value to $110,000.

There are no meeting fees.

In addition to liability insurance, we maintain group life insurance in the amount of $100,000 on each non-employee director for the benefit of each director’s beneficiaries during the time each director serves on the board. The annual cost per director is $174.

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

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 2012.

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.

MDU Resources Group, Inc. Proxy Statement




Proxy Statement

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 to 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 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.

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

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

use of caps on annual incentive awards and long-term incentive stock grant awards (200% of target for awards granted in 2012)

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, rather than an absolute, 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


MDU Resources Group, Inc. Proxy Statement

Proxy Statement


substantive incentive goals measured primarily by return on invested capital 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

R ELATED 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 www.mdu.com.

The audit committee reviews related person transactions in which we are or will be a participant to determine if they are in the best interests of our stockholders and the company. Financial transactions, arrangements, relationships, or any series of similar transactions, arrangements, or relationships in which a related person had or will have a material interest and that exceed $120,000 are subject to the committee’s review.

Related persons are directors, director nominees, executive officers, holders of 5% or more of our voting stock, and their immediate family members. Immediate family members are spouses, parents, stepparents, mothers-in-law, fathers-in-law, siblings, brothers-in-law, sisters-in-law, children, stepchildren, daughters-in-law, sons-in-law, and any person, other than a tenant or domestic employee, who shares the household of a director, director nominee, executive officer, or holder of 5% or more of our voting stock.

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.

The audit committee and the board of directors reviewed two leases between an indirect subsidiary of the company and a Nevada limited liability company, MOJO Montana, LLC (MOJO). John G. Harp, who is chief executive officer of MDU Construction Services Group, Inc. and Knife River Corporation, and his brother, Michael D. Harp, are managing members of MOJO. The properties described in these two leases are located in Kalispell and Billings, Montana, and have been leased since 1998. In May 2010, the audit committee determined that renewing these leases was in the company’s best interests after it reviewed 2010 third party appraisals for the properties and considered the consumer price index and our operating companies’ knowledge of local property markets. The audit committee recommended and the board approved three-year leases for these properties that provide for our indirect subsidiary to pay a combined monthly rent of $9,508 to MOJO. The leases expire June 30, 2013.

C ORPORATE 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/Documents/Governance/CorporateGovernance.pdf. The board of directors has determined that Thomas Everist, Karen B. Fagg, A. Bart Holaday, Dennis W. Johnson, Thomas C. Knudson, Richard H. Lewis, 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.

In determining director independence for 2012, the board of directors considered the following transactions or relationships:

Mr. Everist’s ownership of approximately 1.87 million shares in 2011 and approximately 1.89 million shares in 2012 of our common stock. In December 2011, we entered into a two-year contract with WebFilings, LLC, which offers a cloud-based solution for meeting SEC reporting requirements. The contract provides for a quarterly subscription fee of approximately $13,000 to use WebFilings’ software and for additional fees to be determined based on the number of users and additional services requested. The additional fees for 2011 were $4,500, for 2012 were $5,000, and we expect them to be approximately $3,100 for 2013. Mr. Everist is a limited partner and owns less than 1% of WebFilings, LLC. The MDU Resources Foundation (Foundation) made charitable contributions to Medcenter One Foundation, which is now known as Sanford Health following a merger effective July 2, 2012, in the amount of $500 in 2011 and $1,250 in 2012. Mr. Everist is a member of the board of directors of the Sanford Health Foundation and his wife, Barbara Everist, is vice chairman of the board of trustees of Sanford Health.

charitable contributions from the Foundation in the amount of $2,700 in 2011 and $2,625 in 2012 to the University of North Dakota Foundation – Mr. Holaday serves as the chairman of the board and as a trustee for the University of North Dakota Center for Innovation Foundation and also serves as a director for the University of North Dakota Foundation; charitable contributions from the Foundation in the amount of $3,750 in 2011 and $27,250 in 2012 to Jamestown College or its foundation – Mr. Holaday serves as a trustee for Jamestown College.

charitable contributions from the Foundation to the City of Dickinson in the amount of $20,000 in 2011 and 2012 – Mr. Johnson is president of the City of Dickinson board of commissioners.

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 2012, 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/Documents/Governance/IntegrityGuide.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 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. In August 2012, we amended our bylaws and corporate governance guidelines to 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, and cyber attacks or acts of terrorism. 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.

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 assessment and 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. This opens the opportunity for discussions about areas where the company may have material risk exposure, steps taken to manage those exposures, 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 2012, 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 2012. Director attendance at our annual meeting of stockholders is left to the discretion of each director. Three directors attended our 2012 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/Governance/Pages/BoardChartersandCommittees.aspx. Our corporate governance guidelines are available at http://www.mdu.com/Documents/Governance/CorporateGovernance.pdf, and our Leading With Integrity Guide is also on our website at http://www.mdu.com/Documents/Governance/IntegrityGuide.pdf.

Nominating and Governance Committee
The nominating and governance committee met four times during 2012. The committee members were Karen B. Fagg, chairman, Richard H. Lewis, A. Bart Holaday, 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.

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.

MDU Resources Group, Inc. Proxy Statement




Proxy Statement

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/Governance/Pages/CorporateGovernanceGuidelines.aspx. See also the section entitled “2014 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.

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 2012. The audit committee members are Dennis W. Johnson, chairman, A. Bart Holaday, Richard H. Lewis, and John K. Wilson. The board of directors has determined that Messrs. Johnson, Holaday, Lewis, and Wilson are “audit committee financial experts” as defined by Securities and Exchange Commission regulations and Messrs. Johnson, Holaday, Lewis, and Wilson meet the independence standard for audit committee members under our director independence guidelines and the New York Stock Exchange listing standards, including the Securities and Exchange Commission’s audit committee member independence requirements.

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 auditors, 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 auditors’ qualifications and independence

the performance of our internal audit function and independent auditors 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, 2012, the audit committee has (1) reviewed and discussed the audited financial statements with management; (2) discussed with the independent auditors the matters required to be discussed by the statement on Auditing Standards No. 61, as amended, (AICPA, Professional Standards , Vol. 1, AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T; (3) received the written disclosures and the letter from the independent accountant required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence, and has discussed with the independent accountant the independent accountant’s 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, 2012, for filing with the Securities and Exchange Commission.

Compensation Committee
The compensation committee met five times during 2012. The compensation committee members are Thomas Everist, chairman, Karen B. Fagg, Thomas C. Knudson, and Patricia L. Moss.

The compensation committee’s responsibilities, as set fort h 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 and

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

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 approves 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. Th e chie f 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 committee retained a compensation consultant in 2012 to prepare a competitive assessment for 2013 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 2012, the compensation committee retained Towers Watson to prepare the 2013 competitive assessment covering our Section 16 officers. In an engagement letter dated March 23, 2012, the compensation committee asked Towers Watson to prepare separate executive compensation reviews for the Section 16 officers and for 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 2013 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 2013 salary grade structure

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


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 the competitive data and

address general trends in chief executive officer compensation.

The compensation committee has sole authority to retain, discharge, and approve fees and other terms and conditions for retention of compensation consultants to assist in consideration of the compensation of the chief executive officer, the other Section 16 officers, and the board of directors. 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 2012.

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 2012.

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 2012 compensation review for the board of directors. At its May 2012 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 2011/2012 Director Compensation Report. The committee compared the data to our directors’ compensation and each of its components. After review and discussion of the market data, which indicated that our median director compensation of $165,000 was below the median total direct compensation of $179,596 for large companies in the National Association of Corporate Directors 2011/2012 Director Compensation Report and consistent with the median total direct compensation of $162,002 of the peer companies, the compensation committee recommended, and the board approved, that no changes be made to director compensation for 2012. With respect to non-executive chairman of the board compensation comparison to other directors, the multiple of the median non-executive director total pay for the company was 1.45X as compared to 1.64X under the National Association of Corporate Directors 2011/2012 Director Compensation Report companies and 1.84X for the peer companies. The compensation committee recommended, and the board approved, that no changes be made to the non-executive chairman of the board compensation for 2012.

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.

S ECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 1 6 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 2012 or written representations that no Forms 5 were required, we believe that all such reports were timely filed, except that one Form 4 for Mr. Lewis reporting one transaction was filed one week late.

C ONDUCT 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.

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. Eligible stockholders of record who receive multiple copies of our annual report to stockholders and proxy statement can request householding by contacting us in the same manner. 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.
