GENERAL INFORMATION

This proxy statement contains information related to the annual meeting of shareholders of Martin Marietta Materials, Inc., a North Carolina corporation, to be held on Thursday, May 24, 2012, at 11:30 a.m. at the Corporation’s principal office, 2710 Wycliff Road, Raleigh, North Carolina. The Corporation’s audited financial statements and portions of the Annual Report on Form 10-K for the fiscal year ended December 31, 2011 are being mailed to shareholders with this proxy statement.

This proxy statement, the proxy card, and the notice of meeting are being sent commencing on approximately April 19, 2012 to shareholders of record on March 16, 2012.

What is the purpose of the annual meeting?

At our annual meeting, shareholders will act on the matters outlined in the accompanying notice of annual meeting of shareholders. This statement is furnished in connection with the solicitation by the Board of Directors of the Corporation of proxies to be used at the meeting and at any and all adjournments or postponements of the meeting.

Whether or not you plan to attend the meeting, we encourage you to date, sign, and return your proxy in the enclosed envelope.

Who is entitled to vote at the meeting?

Only shareholders of record at the close of business on March 16, 2012 are entitled to notice of and to participate in the annual meeting. If you were a shareholder of record on that date, you will be entitled to vote all the shares that you held on that date at the meeting, or any adjournments or postponements of the meeting.

What are the voting rights of the holders of Martin Marietta Materials common stock?

Each share of Martin Marietta Materials common stock is entitled to one vote on each matter considered at the meeting.

Who can attend the meeting?

All shareholders as of the record date, or their duly appointed proxies, beneficial owners presenting satisfactory evidence of ownership as of the record date, and invited guests of the Corporation may attend the meeting.

What constitutes a quorum?

The presence at the meeting, in person or by proxy, of the holders of a majority of the common stock outstanding on the record date constitutes a quorum, permitting shareholders to take action at the meeting. On March 16, 2012, there were 45,626,575 shares outstanding of the Corporation’s common stock, $.01 par value per share.

Who will oversee the voting results?

Votes cast by proxy or in person at the annual meeting will be tabulated by an independent inspector of election appointed by the Corporation’s Board of Directors for the annual meeting from American Stock Transfer & Trust Company, the Corporation’s transfer agent. The inspector of election will determine whether a quorum is present. For purposes of determining the presence of a quorum, abstentions and broker non-votes (which are described below) will be counted as shares that are present and entitled to vote.

How do I vote?

If you complete and properly sign the accompanying proxy card and return it to the Corporation, it will be voted as you direct. If you are a registered shareholder and attend the meeting, you may deliver your completed proxy card or vote in person. Shareholders whose shares are held by brokers, banks, or other nominees who wish to vote at the meeting will need to obtain a proxy form from the institution that holds its shares.

Can I change my vote after I return my proxy card?

Yes. Even after you have submitted your vote, you may revoke your proxy at any time prior to its exercise at the annual meeting (i) by filing with the Corporation’s Corporate Secretary an instrument revoking the proxy prior to the meeting, (ii) by the timely delivery to the Corporation’s Corporate Secretary, including at the meeting, of a subsequently dated and executed proxy, or (iii) if you attend the meeting, by voting your shares in person. Attendance at the meeting will not in and of itself constitute a revocation of a proxy.

How do I vote my 401(k) shares?

Each participant in the Corporation’s Performance Sharing Plan and the Savings and Investment Plan may direct the trustee as to the manner in which shares of common stock allocated to the plan participant’s account are to be voted. If the plan participant does not return a signed voting instruction card to the trustee in a timely manner or returns a card without indicating any voting instructions, the trustee will vote the shares in the same proportion as shares for which the trustee receives voting instructions for that plan.

How are brokers required to vote? What are “broker non-votes”?

Brokers holding shares for beneficial owners must vote those shares according to the specific instructions they receive from the beneficial owners. If specific instructions are not received, brokers may generally vote these shares at their discretion. However, the New York Stock Exchange rules preclude brokers from exercising their voting discretion on certain proposals, such as the election of Directors or executive compensation matters. In such cases, absent specific instructions from the beneficial owner, the broker may not vote on those proposals. This results in what is known as a “broker non-vote.” The ratification of the appointment of independent auditors is not such a proposal. Accordingly, if you want your broker to vote your shares on the election of Directors, or the approval on an advisory basis of the compensation of our named executive officers, you must provide specific voting instructions to your broker. Conversely, any broker holding shares for you may vote your shares at their discretion with respect to the ratification of the appointment of independent auditors unless you give them specific instructions on how you wish for them to vote.

Will my broker vote my shares for me on the election of Directors?

Under the New York Stock Exchange rules, the election of Directors and the advisory vote on executive compensation are not considered routine matters and your broker will not be able to vote your shares with respect to those matters if you have not provided directions to your broker. We strongly encourage you to submit your proxy card and exercise your right to vote as a shareholder.

What vote is required to approve each item?

The election of Directors requires a plurality of the votes cast. “Withheld” votes are not counted in determining whether a plurality of votes was received by a Director nominee.

The ratification of the selection of independent auditors, the approval on an advisory basis of the compensation of our named executive officers, and any other proposal presented at the meeting, will be approved if more votes are cast by proxy or in person in favor of the proposal than are cast against it. Abstentions and broker non-votes will not be counted “for” or “against” the proposal.

What are the Board’s recommendations?

Unless you give other instructions on your proxy card, the persons named as proxy holders on the proxy card will vote in accordance with the recommendations of the Board of Directors. The Board’s recommendation, as well as a description of each proposal, is set forth in this proxy statement. The Board recommends a vote:

With respect to any other matter that properly comes before the meeting, the proxy holders will vote as recommended by the Board of Directors or, if no recommendation is given, in their own discretion.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS

FOR THE ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON MAY 24, 2012

This proxy statement, form of proxy card and the accompanying annual report are also available at ir.martinmarietta.com/annuals.cfm.

SECURITY OWNERSHIP OF CERTAIN

BENEFICIAL OWNERS AND MANAGEMENT

Who are the largest owners of the Corporation’s stock?

The following table sets forth information with respect to the shares of common stock which are held by persons known to the Corporation to be the beneficial owners of more than 5% of such stock as of March 16, 2012. To the best of the Corporation’s knowledge, based on filings with the Securities and Exchange Commission as noted below, no person beneficially owned more than 5% of any class of the Corporation’s outstanding voting securities at the close of business on March 16, 2012, except for those shown below.

How much stock do the Corporation’s Directors and executive officers own?

The following table sets forth information as of March 16, 2012 with respect to the shares of common stock that are beneficially owned by the Directors and nominees, the Chief Executive Officer, the Chief Financial Officer, two other executive officers and a former executive officer who resigned during 2011, who are listed in the Summary Compensation Table on page 48 of this proxy statement, individually, and by all Directors and executive officers of the Corporation as a group.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires directors and officers of the Corporation and persons who own more than 10% of the common stock to file with the Securities and Exchange Commission initial reports of ownership and reports in changes in ownership of the common stock. Directors, officers and more than 10% shareholders are required by Securities and Exchange Commission regulations to furnish to the Corporation copies of all Section 16(a) reports filed.

Based solely on its review of the copies of reports furnished to the Corporation and written representations of Directors and officers that no other reports were required for the year ended December 31, 2011, the Corporation believes that no Director, officer, or 10% shareholder failed to timely file in 2011 any report required by Section 16(a).

THE BOARD OF DIRECTORS

The Board of Directors currently consists of ten members, nine of whom are non-employee Directors. The Board is divided into three classes with three-year terms.

The Board of Directors has nominated four persons for election as Directors to serve three-year terms expiring in 2015. Unless otherwise directed, proxies will be voted in favor of these nominees. Each nominee has agreed to serve if elected. Each of the nominees is currently serving as a Director. Should any nominee become unable to serve as a Director, the persons named in the enclosed form of proxy will, unless otherwise directed, vote for the election of such other person for such position as the present Board of Directors may recommend in place of such nominee.

Under our Bylaws, nominations of persons for election to the Board of Directors may be made at an annual meeting of shareholders by the Board of Directors and by any shareholder who complies

with the notice procedures set forth in the Bylaws. As described in the proxy statement for our 2011 annual meeting, for a nomination to be properly made by a shareholder at the 2012 annual meeting, the shareholder’s notice must have been sent to, and received by, our Secretary at our principal executive offices between January 9, 2012 and February 8, 2012. No such notice was received during this period. Should any of the following nominees be unavailable for election by reason of death or other unexpected occurrence, the proxy, to the extent permitted by applicable law, may be voted with discretionary authority in connection with the nomination by the Board of Directors and the election of any substitute nominee.

The following sets forth the age and certain other biographical information for each of the nominees for election and for each of the other members of the Board of Directors as of the date of this proxy statement.

DIRECTOR COMPENSATION

The Corporation uses a combination of cash and stock-based incentive compensation to attract and retain qualified candidates to serve on the Board of Directors. In setting director compensation, the Corporation considers the significant amount of time that Directors expend in fulfilling their duties to the Corporation as well as the skill-level required by the Corporation of members of the Board. The Board determines reasonable compensation for Directors upon recommendation of the Management Development and Compensation Committee of the Board, which retains independent compensation consultants to assist it.

Cash Compensation Paid to Board Members

For the fiscal year ended December 31, 2011, all of the individuals who were then Directors, except Mr. Nye, who was the Chief Executive Officer of the Corporation in 2011 and was not and is not compensated separately for his service as a Director, received an annual retainer of $32,500. Directors received $1,250 for each regular or special meeting of the Board and Board committees attended. Members of the Audit Committee received an additional $5,000 in view of their increased responsibilities. The Chair of the Audit Committee received an additional annual fee of $15,000 in light of his increased responsibilities. Each committee chair (other than the Chairs of the Audit and the Executive Committees) received an annual fee of $8,000. Directors were also reimbursed for travel and other expenses related to attendance at Board and committee meetings. The Corporation’s plane was used to transport some Directors to and from Board and committee meetings, but no Directors received personal use of the Corporation’s plane or other perquisites and personal benefits in 2011. In his role as non-executive Chairman, Mr. Zelnak received $125,000 in addition to the annual retainer in lieu of receiving meeting attendance fees.

Equity Compensation Paid to Board Members

All of the individuals who were Directors in 2011, except Mr. Nye, were granted 1,266 restricted stock units pursuant to the Amended and Restated Stock-Based Award Plan. The restricted stock units granted to the Directors in 2011 were fully vested upon award and will be distributed upon retirement. This component of Director compensation was added in 2009 and replaced annual awards of non-qualified stock options for 3,000 shares that had been made to Directors in previous years. The

Board believes that the use of restricted stock units is more appropriate because of its lower impact on the Corporation’s financial statements and made this determination after input from its independent compensation consultant. The value of the restricted stock unit awards to the Directors is approximately the same as the value of 3,000 shares of stock options at the time of grant.

Deferred Compensation Program for Board Members

Pursuant to the Common Stock Purchase Plan for Directors, non-employee Directors may elect to receive all or a portion of their fees in the form of the Corporation’s common stock, which must be deferred until, at the Director’s election, the date the person ceases to be a Director or the date that is one year and one month following the date that the person ceases to be a Director. Directors may elect to receive payment of the deferred amount in a single lump sum or in equal annual installments for a period up to ten years. Directors may also elect to defer their fees paid in cash on the same basis. The Board of Directors unanimously agreed that a minimum of 50% of each Director’s fees would be paid in common stock and deferred pursuant to the terms of the plan. Amounts deferred under the plan in cash are credited with interest at the prime rate. Amounts deferred under the plan in common stock are credited toward units of common stock at a 20% discount from the fair market value of the common stock (the closing price of the common stock as reported in The Wall Street Journal) on the date the Director fees would otherwise be paid. There are no matching contributions made by the Corporation. The units are converted into common stock of the Corporation pursuant to the terms of the plan. Dividend equivalents are paid on the units at the same rate as dividends are paid to all shareholders. The Directors do not have voting or investment power for their respective units.

CORPORATE GOVERNANCE MATTERS

Corporate Governance Philosophy

The Board of Directors has long believed that good corporate governance is important to ensure the Corporation is managed for the long-term benefit of its shareholders. The Corporation’s business is managed under the direction of the Board of Directors. The Board delegates the conducting of business to the Corporation’s senior management team. The corporate governance standards established by the Board provide a structure within which Directors and management can effectively pursue the Corporation’s objectives for the benefit of its shareholders. Even before the adoption of the Sarbanes-Oxley Act of 2002, one of the most critical components that has governed the way the business affairs of the Corporation are conducted has been the Corporation’s Code of Ethics and Standards of Conduct, which has been in place for more than two decades.

With that backdrop, the Board has endeavored to choose Board and Committee members who are distinguished by a depth of knowledge and experience, to elect a qualified and dedicated management team, and to direct the business affairs of the Corporation to achieve long-term value for shareholders. The Board believes this purpose is particularly important in overseeing the management of a company such as the Corporation that is engaged in a cyclical business where the long-term value for shareholders may not be reflected in current stock prices and which may be temporarily depressed by short-term factors, such as recessionary economies and operating markets.

In furtherance of these goals, in 2002, the Board created a Nominating and Corporate Governance Committee, which consists of three independent Directors. Upon the recommendation of the Nominating and Corporate Governance Committee, the Board of Directors has adopted a set of Corporate Governance Guidelines for the Corporation. The Nominating and Corporate Governance Committee is responsible for overseeing the guidelines and making recommendations to the Board relating to corporate governance matters.

The New York Stock Exchange has adopted rules that require listed companies like the Corporation to adopt governance guidelines and comply with certain standards regarding corporate governance. The Corporation voluntarily implemented these corporate governance rules even prior to their effective date in 2004. The Corporation’s Chief Executive Officer certifies annually to the NYSE that he is not aware of any violation by the Corporation of the NYSE corporate governance listing standards. This certification is in addition to the certification by the Corporation’s Chief Executive Officer and Chief Financial Officer included with the Corporation’s periodic reports filed with the Securities and Exchange Commission. The Corporation also submits written affirmations to the NYSE annually regarding details of the Corporation’s compliance with the corporate governance rules of the NYSE.

The Corporation’s Corporate Governance Guidelines are posted and available for public viewing on the Corporation’s website at www.martinmarietta.com. The guidelines address a wide array of governance issues. Among other matters, the corporate governance principles of Martin Marietta Materials include the following:

Ethics

Board Independence

Independent Board Committees

General

Who are the Corporation’s Independent Directors?

All of the Corporation’s Directors are non-employee Directors except Mr. Nye. Mr. Nye was elected to the Board as of January 1, 2010. Mr. Nye does not sit in the executive sessions of the independent Directors unless invited to attend for a specific discussion nor does he participate in any action of the Board relating to any executive compensation plan in which he may participate.

In assessing the independence of its members, the Board has adopted for the Corporation a set of Guidelines for Director’s Independence. The Guidelines are posted and available for public viewing on the Corporation’s website at www.martinmarietta.com. These Guidelines reflect the rules of the NYSE, applicable requirements of the SEC, and other standards determined by the Board to be important in assessing the independence of Board members. The Board has determined that all members of the Board, except Mr. Zelnak and Mr. Nye, are “independent” under these Guidelines. The Board of Directors has determined that no Director (except Mr. Zelnak and Mr. Nye), or any person or organization with which the Director has any affiliation, has a relationship with the Corporation that may interfere with the Director’s independence from the Corporation and its management.

In making this “independence” determination, the Board considered other entities with which the Directors were affiliated and any business the Corporation had done with such entities. In that regard, Mr. Vinroot is a member of the law firm of Robinson, Bradshaw & Hinson, P.A. located in Charlotte, North Carolina, which provided certain legal services to the Corporation in 2011. Mr. Vinroot did not work on any of the legal matters for the Corporation. The amount of fees paid to Robinson, Bradshaw & Hinson, P.A. for such services in 2011 was approximately $83,000, representing less than 0.2% of the firm’s gross revenues for the last fiscal year. Accordingly, the Board determined that Mr. Vinroot’s relationship with the Corporation, directly and as a partner of Robinson, Bradshaw & Hinson, P.A., was not material for purposes of the independence determination.

Do the independent Directors ever meet without management?

The Corporation’s Corporate Governance Guidelines adopted by the Board provide that at least two Board meetings each year will include an executive session of the non-employee Directors to discuss such topics as they may choose, including a discussion of the performance of the Corporation’s Chairman and its Chief Executive Officer. In 2011, the Corporation’s non-employee Directors met 4 times in executive session without management, in addition to executive sessions held by committees of the Board. The Chair of the Nominating and Corporate Governance Committee, currently Mr. McDonald, a non-employee Director, presides at these executive sessions of non-employee Directors. In the absence of such Chair, the non-employee Directors would elect from among themselves a chair for such an executive session.

What is the Board’s leadership structure?

As of January 1, 2010, the role of Chairman and Chief Executive Officer are separate. The Board believes this structure is best currently for the Corporation as Mr. Zelnak’s continuance as Chairman furthers a seamless transition in connection with the succession of Mr. Nye as Chief Executive Officer. The Corporation also believes that the Board leadership structure wherein the Chairman of the Nominating and Corporate Governance Committee presides at executive sessions of the Board, at which Mr. Nye does not attend unless specifically invited, facilitates communication among the non-employee Directors. We believe our Chief Executive Officer and our Chairman have an excellent working relationship that has allowed Mr. Nye to make a strong transition into his role and will allow him to focus on the challenges the Corporation is facing in the current business environment. We believe Mr. Zelnak’s continuation as Chairman provides strong leadership for our Board, while also positioning our Chief Executive Officer as the leader of the Corporation as recognized by our customers, employees and other constituencies.

What is the Board’s role in risk oversight?

Our Board currently has eight independent members and only two non-independent members, the non-executive Chairman and the Chief Executive Officer. A number of our independent Board members are serving or have served as members of senior management of other public companies, have served as directors of other public companies, and otherwise have experience and/or educational backgrounds that we believe qualify them to effectively assess risk. Each of our Board Committees, including our Audit, Management Development and Compensation, and Nominating and Corporate Governance Committees, are comprised solely of independent Directors, each with a different independent Director serving as Chair of the Committee (other than the Executive Committee, which does not meet on a regular basis).

The Board has overall responsibility for oversight of risk management. The Board believes that an effective risk management system will (1) timely identify the material risks that the Corporation faces, (2) communicate necessary information with respect to material risks to senior executives and, as appropriate, to the Board or relevant Board Committee, (3) determine whether the risk is excessive or appropriate under the circumstances and designed to achieve a legitimate corporate goal, (4) implement risk management responses consistent with the Corporation’s risk profile, and (5) integrate risk management into the Corporation’s decision-making.

The Board delegates certain responsibilities to Board Committees to assist in fulfilling its risk oversight responsibilities. Each of the Committees reports regularly to the full Board of Directors as to actions taken and topics discussed. In addition, the Board reviews with management regularly the most significant risks facing the Corporation, the probabilities of those risks occurring, the steps taken to mitigate any impact of risks, and management’s general risk management strategy. In addition, the Board encourages management to promote a corporate culture that incorporates risk management into the Corporation’s day-to-day operations.

The Board has designated the Audit Committee to take the lead in overseeing risks related to financial reporting, financial statements, internal control environment, internal audit, independent audit, and accounting processes. The Finance Committee evaluates risks associated with the Corporation’s capital structure, including credit and liquidity risks. The Management Development and Compensation Committee oversees aspects of risk related to the annual performance evaluation of our Chief Executive Officer, succession planning and ensuring that executive compensation is appropriate to meet the Corporation’s objectives. The Nominating and Corporate Governance Committee oversees aspects of risk related to the composition of the Board and its Committees, Board performance and best practices in corporate governance. The Ethics, Environment, Safety and Health Committee monitors risks in the areas of the Corporation’s ethics program, health, safety, and the environment.

While the Board oversees the Corporation’s risk management, the executive officers are responsible for the day-to-day risk management processes. We believe this division of responsibilities is the most effective approach for addressing the risks facing our Corporation and is appropriate whether the positions of Chairman and Chief Executive Officer are separate or held by the same individual.

How would interested parties make their concerns known to the independent Directors?

The Board of Directors provides a process for shareholders and other interested parties to send communications to the Board. Shareholders and other interested parties may communicate anonymously and confidentially with the Board through the Corporation’s Ethics Hotline at 1-800-209-4508. The Board has also designated the Corporate Secretary to facilitate communications to the Board. Shareholders and other interested parties may communicate directly with the Board of Directors, or directly with non-management Directors, or an individual Director, including the Chair of the Nominating and Corporate Governance Committee, by writing to Martin Marietta Materials, Inc., Attn: Corporate Secretary, 2710 Wycliff Road, Raleigh, North Carolina 27607-3033.

All communications by shareholders or other interested parties addressed to the Board will be sent directly to Board members. While the Corporation’s Ethics Office and the Corporate Secretary may review, sort, and summarize these communications, all direct communications will be presented to the non-management Directors unless there is instruction from them to filter such communications (and in such event, any communication that has been filtered out will be made available to any non-management Director who wishes to review it).

The Corporation and its Board of Directors will continue to review and evaluate the process by which shareholders or other interested persons communicate with the Corporation and the Board and may adopt other or further processes and procedures in this regard. If so, the Corporation will identify those policies and procedures on its website at www.martinmarietta.com.

How often did the Board meet during 2011?

The Corporation’s Board of Directors held 7 meetings during 2011, five of which were regularly scheduled meetings and two of which were special meetings. There were also a total of 24 committee meetings in 2011. In addition, management confers frequently with its Directors on an informal basis to discuss Corporation affairs.

How many times did Directors attend meetings of the Board and its Committees?

In 2011, all Directors attended all of the meetings of the Board of Directors. All directors attended all of the meetings of the committees of the Board on which they served (during the periods that they served).

Will the Directors attend the Annual Meeting?

The Corporation’s Directors are expected to attend the Corporation’s Annual Meeting of Shareholders. All Directors then serving on the Board attended the 2011 Annual Meeting of Shareholders.

How are Directors compensated?

A table showing the compensation paid by the Corporation to the individuals serving as Directors in 2011, other than Mr. Nye, is included in the section of this proxy statement entitled “DIRECTOR COMPENSATION — Director Compensation Table.” Mr. Nye, who was elected a Director as of January 1, 2010, is not included in the table. Mr. Nye’s compensation as an executive officer of the Corporation is shown in the section entitled “EXECUTIVE COMPENSATION” and he received no additional compensation for service as a Director during that time.

What Committees has the Board established?

The Corporation’s Board of Directors has six standing committees: the Audit Committee, the Ethics, Environment, Safety and Health Committee, the Executive Committee, the Finance Committee, the Management Development and Compensation Committee, and the Nominating and Corporate Governance Committee.

The Audit Committee, which is composed entirely of non-employee, independent Directors, held 8 meetings during 2011. The Audit Committee meets periodically and separately in executive sessions with management, the independent auditors, and the Corporation’s internal auditors to review the activities of each. The Audit Committee possesses and may exercise the powers of the Board of Directors relating to accounting, auditing, and financial reporting matters of the Corporation, except when such powers are by statute or the Articles of Incorporation or Bylaws reserved to the full Board or delegated to another committee of the Board. The Audit Committee reports regularly to the full Board on these matters. The Audit Committee is directly responsible for the appointment, compensation, and oversight of the Corporation’s independent auditors. Among other duties, the Audit Committee:

The Committee’s current members are Directors Maffucci (Chair), Menaker, Perez, and Rediker. The Board of Directors has determined that the Chair of the Audit Committee, Mr. Maffucci, qualifies as an “audit committee financial expert” as defined in rules adopted by the SEC. The Board has also determined that Mr. Maffucci, and the other members of the Audit Committee, are independent of management, as required by the rules of the NYSE, SEC, and the Board’s Guidelines for Director’s Independence.

The Ethics, Environment, Safety and Health Committee held 2 meetings during 2011. It monitors compliance with the Corporation’s Code of Ethics and Standards of Conduct and reviews all matters presented to it by the Corporate Ethics Officer concerning the ethical practices of the Corporation and its Directors, officers, and employees, including conflicts or potential conflicts of interest between the Corporation and any of its Directors, officers, and employees. The Committee also reviews and monitors the adequacy of the Corporation’s policies and procedures and organizational structure for ensuring compliance with environmental laws and regulations, and matters relating to health and safety. The Committee’s current members are Directors Vinroot (Chair), Menaker, Perez, Quillen, and Rediker.

The Executive Committee held no meetings during 2011. It has the authority to act during the intervals between the meetings of the Board of Directors and may exercise the powers of the Board in the management of the business and affairs of the Corporation as may be authorized by the Board of Directors, except to the extent such powers are by statute, the Articles of Incorporation or Bylaws reserved to the full Board. The Committee’s current members are Directors Zelnak (Chair), McDonald, and Menaker.

The Finance Committee held 5 meetings during 2011. It has been delegated general oversight powers related to the management of the financial affairs of the Corporation, including but not limited to, establishing lines of credit or other short-term borrowing arrangements and investing excess working capital funds on a short-term basis. The Committee reviews and makes recommendations to the Board of Directors concerning changes to capital structure, including the incurrence of long-term debt, issuance of equity securities, share repurchases, and the payment of dividends, as well as capital expenditures and the contributions budget. The Committee’s current members are Directors Perez (Chair), Maffucci, Quillen, and Rediker.

The Management Development and Compensation Committee held 6 meetings during 2011. It is composed entirely of non-employee, independent Directors, as required by the rules of the NYSE, who are also “non-employee” and “outside” Directors as those terms are defined by Rule 16b-3 promulgated under the Securities and Exchange Act of 1934 and Section 162(m) of the Internal Revenue Code of 1986. The Committee possesses and may exercise the powers of the Board of Directors relating to management development and compensation matters of the Corporation, except when such powers are by statute, the Articles of Incorporation or Bylaws reserved to the full Board or delegated to another committee of the Board. The Committee reports regularly to the full Board on these matters. The purposes of the Committee are to:

The Committee has the power, in its sole discretion, to determine the compensation and benefits to be paid for all elected officers and employees. The Committee also approves and administers the grants of stock options and any other equity-based awards that may be granted by the Corporation.

The Committee reviews and approves the Corporation’s goals and objectives for Chief Executive Officer’s compensation, evaluates the Chief Executive Officer’s performance in light of those goals and objectives, and determines and approves the Chief Executive Officer’s compensation level based on the Committee’s evaluation, which includes executive sessions with the independent

directors of the Board of Directors. The Committee also reviews management’s assessment of the performance of other elected officers, and reviews and approves the salary, bonus, and other compensation of such elected officers. The Committee has the authority, in its sole discretion, to retain, pay, and terminate any consulting firm, if any, used to assist in evaluating director, chief executive officer, or senior executive compensation. The Committee has authority to delegate any of its duties under its charter, including to the Chair of the Committee, as it deems appropriate. The Committee also reviews with management at least annually plans for the orderly development and succession of executive management of the Corporation. The Committee’s current members are Directors Cole (Chair), McDonald, Menaker and Quillen.

The Nominating and Corporate Governance Committee held 3 meetings in 2011. The Committee is composed entirely of non-employee, independent Directors, as required by the rules of the NYSE. The Committee possesses and may exercise the powers of the Board of Directors relating to the process of governance of the Corporation, except when such powers are by statute, the Articles of Incorporation or Bylaws reserved to the full Board or delegated to another committee of the Board. The Committee reports regularly to the full Board on these matters. The purposes of the Committee are to:

The Committee also oversees the evaluation of the Board and its committees. The Committee has the sole authority to retain, pay, and terminate search firms, if any, used to identify Director candidates. The Committee’s current members are Directors McDonald (Chair), Cole, and Vinroot.

Upon the recommendation of this Committee, the Board of Directors has adopted a set of Corporate Governance Guidelines for the Corporation. The Guidelines are posted and available for public viewing on the Corporation’s website at www.martinmarietta.com. A copy may also be obtained upon request from the Corporation’s Corporate Secretary. Additional information concerning the corporate governance process of the Corporation is contained in the section entitled “CORPORATE GOVERNANCE MATTERS” above.

Will the Nominating and Corporate Governance Committee consider any Director candidates recommended by shareholders?

The Nominating and Corporate Governance Committee will consider nominees recommended by shareholders for election as a Director at an annual meeting of shareholders of the Corporation, if the shareholder making such recommendation complies with the advance notice provisions of the Bylaws of the Corporation. The Bylaws of the Corporation require advance notice for any proposal for the nomination for election as a Director at an annual meeting of shareholders that is not included in the Corporation’s notice of meeting or made by or at the direction of the Board of Directors. In general, nominations must be delivered to the Secretary of the Corporation at its principal executive offices, 2710 Wycliff Road, Raleigh, North Carolina 27607, not less than 60 days nor more than 90 days prior to the first anniversary of the mailing of the proxy statement in connection with the preceding year’s annual meeting of shareholders and must contain specified information concerning the nominee and the shareholder proposing the nomination. Any shareholder desiring a copy of the Bylaws of the

Corporation will be furnished a copy without charge upon written request to the Secretary of the Corporation. Since the 2011 annual meeting, the Corporation has not made any material changes to the procedures by which shareholders may recommend nominees to the Corporation’s Board of Directors. Additional information is contained in the section entitled “SHAREHOLDERS’ PROPOSALS FOR 2013 ANNUAL MEETING” below.

How does the Board select nominees for the Board?

The Nominating and Corporate Governance Committee will consider candidates for Board membership suggested by its members and other Board members, as well as management and shareholders. The Committee has also retained a third-party executive search firm to identify potential candidates for its consideration from time to time. The Committee makes an initial determination as to whether to conduct a full evaluation of the candidate, and reviews all information provided to the Committee, including the recommendations for the prospective candidate and the Committee’s own knowledge of the prospective candidate. If the Committee determines that additional consideration is warranted, interviews are conducted by the members of the Committee, as well as the Chief Executive Officer of the Corporation; appropriate inquiries are conducted into the background and qualifications of potential candidates; the Committee meets to discuss its evaluation and feedback from the Chief Executive Officer; and, if the Committee determines to do so, it makes a recommendation to the full Board as to the persons who should be nominated by the Board. The Board of Directors determines the nominees after considering the recommendation and report of the Committee.

In evaluating any potential candidate, the Nominating and Corporate Governance Committee considers the extent to which the candidate has the personal characteristics and core competencies outlined in the Guidelines for Potential New Board Members adopted by the Committee, and takes into account all other factors it considers appropriate. A copy of these Guidelines is attached to this proxy statement as Appendix A.

The Board of Directors, acting through the Committee, is responsible for presenting for shareholder consideration a group of Board candidates that, taken together, have the experience, qualifications, attributes and skills appropriate for functioning effectively as a Board and providing oversight to the Corporation. The Committee looks for certain characteristics common to all Board members, including integrity, strong professional reputation, mature business judgment, record of achievement, constructive and collegial personal attributes, and the ability and commitment to devote sufficient time and energy to Board service. In addition, the Committee seeks to include on the Board a complementary mix of individuals with diverse backgrounds and skills reflecting the broad set of challenges that the Board confronts. These individual qualities include matters such as experience in the mining or manufacturing industry, technical experience in financial or accounting matters, experience gained in situations comparable to the Corporation’s which has grown through acquisitions, leadership experience, public company Board membership or executive officer experience, and relevant geographical experience.

Although the Committee does not have a formal policy regarding Board diversity, matters of diversity (including diversity in professional experience, geographic background reflecting the Corporation’s geographic base, education, ethnic background and gender) are included in the many characteristics considered by the Committee in evaluating nominees for election as directors as reflected in the Corporation’s Guidelines for Potential New Board Members. The Committee considers

all candidates in the context of the qualifications enumerated above, as well as their complementary experiences, backgrounds and skills, in an effort to maintain a strong and effective Board of Directors. The Nominating and Corporate Governance Committee also assesses, through discussions at Committee and Board of Directors meetings, the effectiveness of its efforts with respect to diversity and consideration of its Guidelines for Potential New Board Members when it periodically reviews the overall composition of the Board and as part of its self-evaluation process. In addition to these qualities, the Committee has considered the special characteristics outlined in the Directors’ biographies on pages 7-13 of this Proxy Statement, which has led the Committee to conclude that the current Board members, including the nominees for election, have the appropriate characteristics to serve as members of the Board of Directors.

Each nominee approved by the Nominating and Corporate Governance Committee and recommended for election at the 2012 Annual Meeting is a current Director standing for re-election. The Committee received no additional recommendations for Director nominees for consideration at the annual meeting.

Do the Board Committees have charters? How can shareholders obtain them?

The Corporation’s Board of Directors has adopted written charters meeting the requirements of the NYSE for the Audit Committee, Management Development and Compensation Committee, and Nominating and Corporate Governance Committee. These charters address the purposes and responsibilities of each committee, as described above, and provide for an annual performance evaluation of each committee. Copies of these charters are posted on the Corporation’s website at www.martinmarietta.com, along with copies of the Corporation’s Corporate Governance Guidelines, Code of Ethics and Standards of Conduct, and Guidelines for Director’s Independence.

How are transactions with persons related to the Corporation reviewed?

The SEC requires the Corporation to disclose in this proxy statement certain transactions in which the Corporation participates and in which certain persons considered “related persons” of the Corporation have a direct or indirect material interest. These “related persons” would include the directors and executive officers of the Corporation, nominees for director, certain control persons, and their immediate family members.

Each director, executive officer, and nominee for director of the Corporation receives and agrees to abide by the Corporation’s Code of Ethics and Standards of Conduct. The Corporation considers that any transaction in which the Corporation participates and in which any related person of the Corporation has a direct or indirect material interest will be subject to the Corporation’s Code of Ethics and Standards of Conduct and subject to review, approval or ratification, as appropriate under the circumstances, by the Corporation under the standards enumerated in the Corporation’s Code of Ethics and Standards of Conduct. If a proposed transaction is one in which a Director of the Corporation has an actual or potential conflict of interest, it will be subject to review by the Chairman of the Board of Directors and the Chairman of the Nominating and Corporate Governance Committee.

Any waivers of the Code of Ethics and Standards of Conduct for Directors and executive officers may be made only by the Corporation’s Board of Directors or any committee to which it delegates that authority. Any waivers for Directors and executive officers and any amendments to the Code of Ethics and Standards of Conduct will be promptly disclosed to the Corporation’s shareholders.

In assessing the independence of its members, the Board considers any interests a director may have in any transactions in which the Corporation participates. The Board also considers other entities with which the Directors are affiliated and any business the Corporation has done with such entities.

PROPOSAL 2

INDEPENDENT AUDITORS

(Item 2 on Proxy Card)

The Board of Directors recommends that the shareholders ratify the appointment of Ernst & Young LLP, an independent registered public accounting firm, to audit the consolidated financial statements of the Corporation and the effectiveness of the Corporation’s internal control over financial reporting for the fiscal year 2012. The ratification of the appointment of Ernst & Young LLP is being submitted to the shareholders because management believes this to be good corporate practice. Should the shareholders fail to ratify this appointment, the Board of Directors and its Audit Committee will review the matter.

Ernst & Young LLP served as the Corporation’s independent auditors for 2011 and audited the consolidated financial statements of the Corporation for the year ended December 31, 2011 and the effectiveness of the Corporation’s internal control over financial reporting as of December 31, 2011. In connection with the audit of the Corporation’s 2011 financial statements, the Corporation entered into an engagement letter with Ernst & Young LLP that sets forth the terms by which Ernst & Young LLP would perform audit services for the Corporation. Ernst & Young LLP required that the audit engagement agreement be subject to alternative dispute resolution procedures and an exclusion of punitive damages.

The Audit Committee is solely responsible for retaining or terminating the Corporation’s independent auditors in 2012. Representatives of Ernst & Young LLP are expected to attend the Annual Meeting of Shareholders of the Corporation, will have the opportunity to make a statement if they so desire, and will be available to respond to questions from shareholders.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” RATIFICATION

OF THE SELECTION OF ERNST & YOUNG LLP AS INDEPENDENT AUDITORS.

Summary of Fees

The following table summarizes the aggregate fees billed for professional services rendered to the Corporation by Ernst & Young LLP in 2011 and 2010. A description of these various fees and services follows the table.

Audit Fees

The aggregate fees billed for professional services rendered by Ernst & Young LLP to the Corporation for each of 2011 and 2010 in connection with the annual financial statement audit, the annual internal controls audit, and reviews of the Corporation’s financial statements included in the quarterly reports on Form 10-Q were $1,483,000 and $1,198,000, respectively. During 2011, Ernst & Young also billed the Corporation $330,000 related to the filing of the S-4 registration statement related to the proposed business combination with Vulcan Materials Company.

Audit-Related Fees

The aggregate fees billed for professional services rendered by Ernst & Young LLP to the Corporation for each of 2011 and 2010 in connection with audit-related services, including subsidiary audits and continuing education, were $102,000 and $99,000, respectively.

Tax Fees

The aggregate fees billed for professional services rendered by Ernst & Young LLP to the Corporation for each of 2011 and 2010 in connection with tax advice, including consultation on transfer pricing issues, and other tax-related activities were $70,000 and $104,000, respectively.

All Other Fees

There were no other fees billed for other professional services rendered or products provided by Ernst & Young LLP to the Corporation for 2011 and 2010.

Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy that requires advance approval of all audit, audit-related, tax services, and other services performed by Ernst & Young LLP. The policy provides for pre-approval by the Audit Committee of specifically defined audit and non-audit services. Unless the specific service has been previously pre-approved with respect to that year, the Audit Committee must approve the permitted service before Ernst & Young LLP is engaged to perform it. The Audit Committee has delegated to the Chair of the Audit Committee authority to approve permitted services, provided that the Chair reports any decision to the Committee at its next scheduled meeting.

Audit Committee Review

In connection with the Audit Committee’s review of services rendered and fees billed by Ernst & Young LLP, the Audit Committee has considered whether the provision of the non-audit related services described above is compatible with maintaining the independent auditors’ independence and has concluded that the provision of these services does not compromise such independence.

AUDIT COMMITTEE REPORT

The Audit Committee operates under a written charter adopted by the Board of Directors, which is reassessed at least annually for adequacy by the Audit Committee. The Directors who serve

on the Audit Committee have no financial or personal ties to the Corporation (other than Director compensation and equity ownership as described in this proxy statement) and are all “independent” for purposes of the Securities and Exchange Commission’s regulations, the New York Stock Exchange listing standards, and the Guidelines for Director’s Independence adopted by the Board of Directors. The Board of Directors has determined that none of the Audit Committee members has a relationship with the Corporation that may interfere with the Director’s independence from the Corporation and its management. Copies of the Audit Committee’s charter and the Corporation’s Guidelines for Director’s Independence can be viewed on the Corporation’s website at www.martinmarietta.com.

The Board of Directors has charged the Audit Committee with a number of responsibilities, including review of the adequacy of the Corporation’s financial reporting, accounting systems, and internal controls. The Corporation’s independent auditors and the vice president of the internal audit function report directly and are ultimately accountable to the Audit Committee.

In the discharge of its responsibilities, the Audit Committee has reviewed and discussed with management and the independent auditors the Corporation’s audited financial statements for fiscal year 2011. In addition, the Committee has discussed with the independent auditors matters such as the quality (in addition to acceptability), clarity, consistency, and completeness of the Corporation’s financial reporting, as required by Statement on Auditing Standards No. 114, as amended (AICPA, Professional Standards, Vol. 1, AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

The Audit Committee has received from the independent auditors written disclosures and a letter concerning the independent auditors’ independence from the Corporation, as required by the Public Company Accounting Oversight Board in Rule 3526, Communications with Audit Committees Concerning Independence, and has discussed with the independent auditors the independent auditors’ independence. The Audit Committee also received from the independent auditors a letter indicating there were no material issues raised by the independent auditors’ most recent internal quality control review, or by any inquiry or investigation by governmental or professional authorities within the preceding five years. These disclosures have been reviewed by the Committee and discussed with the independent auditors.

Based on these reviews and discussions, the Audit Committee has recommended to the Board that the audited financial statements be included in the Corporation’s 2011 Annual Report on Form 10-K for filing with the Securities and Exchange Commission.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

This Executive Summary provides an overview of our performance in 2011, the factors influencing it, and how executive compensation in 2011 was tied to such performance. Our compensation philosophy and programs are set out in more detail below in this Compensation Discussion and Analysis.

At our 2011 annual meeting of shareholders, our shareholders expressed their continued support of our executive compensation programs by approving our non-binding advisory vote on our executive compensation. More than 90% of votes cast supported our executive compensation policies and practices. During our 2011 fiscal year, we reviewed our executive compensation programs in conjunction with our business results and our shareholder support of our executive compensation program. Following such review and consideration, we continue to believe that our executive compensation programs are designed to support our company and our business strategies in concert with our compensation philosophy.

The economic recession that has impacted the construction materials industry for several years continued in 2011. Aggregates shipments in the United States experienced an unprecedented decline of almost 40% from their peak volume in 2006. Federal highway legislation funding, which expired in September 2009, was provided under an eighth continuing resolution (currently extended to June 30, 2012), leading to adoption of a focus on short-term repair and maintenance of highways, roads and bridges and creating uncertainty around long-term highway funding. In addition, states continued to balance funding of construction spending against budget shortfalls caused by decreasing tax revenues and uncertainty related to long-term highway funding.

Against this background, the Corporation continued to execute on its strategic plan while delivering strong performance in 2011:

Management was able to achieve these performance results in 2011 by effectively improving the Corporation’s cost structure without jeopardizing the long-term value of the business, allowing us to become more profitable when volumes begin recovering. The number of employees has remained at a reduced level since 2009 (even considering the additional approximately 600 employees that were added net in 2011 due to acquisitions) and is nearly identical to the number of employees in 1997. However, we managed nearly three times more assets and produced nearly 25% greater gross profit per ton in 2011 than in 1997, which reflects the greater efficiencies we have been able to successfully achieve in the business in addition to reducing costs. These actions have contributed to the following results:

The strong financial results for 2011 are accompanied by other achievements in 2011 that are reflective of the discipline of our executive management team. Mr. Nye and the other executive officers demonstrated solid execution of our business plan and the promotion of our strategic objectives focusing on long-term growth, which was reflected by the following acquisitions and growth initiatives:

Management was able to seize these growth opportunities because of its discipline in managing costs and maintaining a healthy balance sheet, and its experience in successfully concluding acquisitions.

The Management Development and Compensation Committee (the “Committee”) reviewed executive compensation in 2011 in light of these factors. The Committee used data from a variety of sources, including its independent compensation consultant, to achieve its goal of attracting and retaining qualified executives who will make decisions that achieve long-term success for the Corporation without sacrificing integrity, safety and other important principles. The Committee also was mindful of pay-for-performance objectives and sought to avoid practices that would encourage excessive risk-taking. In furtherance of these goals, the main elements of our compensation program are base salary, annual cash bonus, and long-term equity incentive awards. The Committee took into account a number of factors in determining compensation for 2011, including our financial results, individual performance, competitive data, and other factors, as detailed in the Compensation Discussion and Analysis. In light of these considerations, the Committee made the following compensation decisions for 2011:

The pay-for-performance component of compensation in 2011 consisting of annual and long-term compensation, which comprises most of the compensation in 2011 for the named executive officers, are shown below with respect to (1) Mr. Nye and (2) all the named executive officers other than Mr. Nye.

We believe that our executive compensation program is reasonable, competitive, and strongly focused on pay-for-performance. The compensation of our named executive officers varies depending upon the achievement of pre-established performance goals, both corporate and individual. The

majority of the target compensation opportunities for our named executive officers in 2011 were performance-based. Through equity incentives and mandatory investment of a portion of the annual bonus award in common stock units through the Incentive Stock Plan (discussed on pages 41 to 43), we also align the interests of our executives with those of our shareholders and the Corporation’s long-term interests, and also help retain executives over time. Our executive compensation policies have enabled us to attract and retain talented and experienced senior executives. We believe that the compensation of our named executive officers in 2011 was consistent with the Corporation’s performance in 2011 and appropriate to align it with the Corporation’s growth in future years.

Compensation Philosophy and Objectives

We believe that our employees are the Corporation’s most important resource. In developing our executive compensation policies, the Board of Directors, through the Management Development and Compensation Committee, focuses on two primary objectives: compensating our executive officers in a manner that is fair, reasonable and competitive and structuring executive compensation programs to provide incentives consistent with our strategic goals. The executive compensation program is designed to reward high performance in achieving both annual and long-term goals that have the ultimate objective of improving shareholder value. We measure the achievement of goals not only in terms of financial performance, but also by evaluating ethical conduct, safety performance, effectiveness of our internal controls and other factors as determined by the Committee. In 2011, as in prior years, the Committee evaluated financial performance by reference to our operating performance rather than short-term changes in stock price based on its view that our long-term operating performance will be reflected by stock price performance over the long-term. The Board believes this purpose is particularly important in overseeing the management of a company such as the Corporation that is engaged in a cyclical business where the long-term value for shareholders may not be reflected in current stock prices and which may be temporarily depressed by short-term factors, such as recessionary economies and operating markets. The types of compensation and benefits provided to the named executive officers are similar to those provided to other executive officers.

Executive Compensation Policies

The Committee considers the following objectives in setting executive compensation:

The Role of the Management Development and Compensation Committee

The Committee is responsible for carrying out the philosophy and objectives of the Board of Directors related to executive compensation in addition to its responsibilities of overseeing the development and succession of executive management of the Corporation. The Committee has the authority to determine compensation and benefits for the Corporation’s executive officers. The Committee members are each non-employee, independent Board members pursuant to the New York Stock Exchange rules, and the Committee operates pursuant to a written charter, a copy of which can be viewed on the Corporation’s website at www.martinmarietta.com.

The performance of the Chief Executive Officer and each other executive officer is reviewed regularly by the Committee. Based on this review, the Committee sets compensation for all executive officers. Compensation decisions with respect to the executive officers other than the Chief Executive Officer are based in part on recommendations by the Chief Executive Officer, with input from the Senior Vice President — Human Resources, with respect to salary adjustments and annual cash and equity awards. The Committee can accept, reject or modify any recommended adjustments or awards to executive officers. For the Chief Executive Officer, the Committee sets the levels of annual adjustments and awards based on the criteria it deems to be appropriate under the circumstances. There are no employment agreements between the Corporation and any executive officer of the Corporation, including the Chief Executive Officer.

The Committee uses a mix of annual and long-term compensation to provide a total compensation structure that is designed to motivate executives to achieve the business goals set by the Corporation and reward the Corporation’s executives when they achieve those goals. Although the Committee has no specific pre-established policy or target for the allocation between either cash and non-cash or short-term and long-term compensation, the pay mix is largely dictated by competitive market practice combined with a philosophy of calibrating incentive levels to performance results. The Committee determines the percentage mix of compensation that it believes is appropriate for each of the executive officers based on their judgment and experience, compensation information compiled by management, recommendations of the Chief Executive Officer (except for his own compensation) and information provided by independent compensation consultants. In 2011, in light of the Corporation’s positive performance despite the lengthy economic recession, the Committee reevaluated its compensation philosophy to ensure that it appropriately compensated its executive officers based on the Corporation’s performance but also allowed the Corporation to attract and retain excellent managers. In the Committee’s view, this was especially important given the decreased bonus and long-term equity grants being made due to the Corporation’s lower operating performance despite significant efforts being made by executive officers that will better position the Company for growth when the economy improves. In this regard, the Committee reaffirmed its philosophy of looking at total compensation, with long-term equity targets at or about median, although actual pay would be below median.

The Committee in 2011 was advised by Towers Watson & Co. pursuant to an engagement as the Committee’s independent compensation consultant to assist it in reviewing the Corporation’s executive compensation program to ensure that the program is consistent with the Board’s philosophy and to provide valuable information and insight as to market pay practices. Towers Watson conducted an extensive review and benchmarking study of the Corporation’s compensation program in 2007. In addition, it reviews and provides comments on management’s annual competitive analysis of each

component of compensation and total compensation for the Chief Executive Officer and executive officers of the Corporation. Towers Watson provides the Committee with relevant market data and alternatives to consider when making compensation decisions for the Chief Executive Officer. Towers Watson also provides feedback to management on proxy information and published compensation surveys, which are then used by the Chief Executive Officer in making recommendations to the Committee with respect to compensation for executive officers other than the Chief Executive Officer. The Committee and/or the Committee Chairman from time to time in 2011 met with Towers Watson in private sessions without management present.

The Committee assessed and discussed the performance and independence of its executive compensation consultant in 2011. As part of this assessment, the Committee considered the extent of other business that Towers Watson performed for the Corporation and reviewed the safeguards that were in place to ensure the independence of the advice they received. A different office of Towers Watson performed actuarial, retirement plan, welfare plan and benefits consulting services for the Corporation, for which we paid $981,000 in 2011. Management reported to the Committee the amount and nature of such other business provided to the Corporation. Towers Watson’s fees for executive compensation services in 2011 were $124,000. The Committee reviewed various factors regarding Towers Watson’s independence, including the cost of the work Towers Watson performed for the Corporation, and concluded that adequate barriers and safeguards were in place to ensure that Towers Watson’s executive compensation recommendations were not in any way influenced by this other business. The Committee further concluded that Towers Watson was not unduly influenced by management and was providing objective and independent executive compensation advice.

Compensation and Risk-Taking

We believe our executive pay is reasonable and provides appropriate incentives to our executives to achieve our financial and strategic goals without encouraging them to take excessive risks in their business decisions. Compensation program features that mitigate against risks include the following:

The Use of Benchmarking Information

The Committee reviews compensation information drawn from various sources, including proxy statements of a peer group of the following companies that we selected primarily from the Standard and Poor’s 1500 Basic Materials Index with other companies added to the group, that are in the aggregates, cement, natural resources and specialty chemical industries based on similarities in revenue and business characteristics: Albermarle Corporation, Alpha Natural Resources, Inc., Amcol International Corporation, Arch Coal, Inc., FMC Corporation, Georgia Gulf Corporation, Granite Construction Inc., Kansas City Southern, Louisiana- Pacific Corporation, Packaging Corporation of America, Patriot Coal Corporation, Universal Forest Products Inc., The Valspar Corporation and Vulcan Materials Company (the “Compensation Peer Group”). These peer companies changed from previous years to include companies that are more comparable to the Corporation as to size and mix. The Compensation Peer Group was used by the Committee for data related to base and bonus compensation because of the Committee’s view that it competes for executive officers and employees from companies that are represented by this group. However, in 2011 the Committee decided to formulate and use a different peer group for comparisons related to executive performance based on its view that investors consider the performance of these public companies when deciding to make an investment in the construction materials sector. This peer group consists of Cemex, S.A.B. de C.V., CRH PLC, Heidelberger Druckmaschinen AG/Heidelberg USA, Holcim Ltd., Lafarge S.A. and Vulcan Materials Company (the “Performance Peer Group”).

Because the information in the proxy statements or other reports of these companies generally does not provide precise comparisons by position to our executive officers, the Committee also takes into consideration published independent compensation surveys of companies with revenue in the range of $1.5 billion to $2.0 billion as to median levels for each executive officer. As to the Chief Executive Officer’s compensation, the Committee reviews compensation information derived from both the Compensation Peer Group described above and the published surveys described in the preceding sentence, as well as the advice of Towers Watson. The Committee considered this benchmarking information in November 2010 in setting Mr. Nye’s base salary and for the other components of his 2011 compensation.

In general, the Committee compares annual base salaries to the median compensation levels or the 50^th percentile and 75^th percentile of executive officers performing similar job functions at the companies in both the peer group survey and the published surveys described above that were reviewed. The same peer group survey was used to consider compensation for the Chief Executive Officer, the Chief Financial Officer and the executive officers responsible for operations. The published surveys described above are used to consider compensation for the Chief Executive Officer and all the named executive officers. The Committee also reviews a range of market pay for similarly-situated executive officers. It also compares targets for all variable pay, which is compensation other than base salaries, to the median level. The variable pay is based on specific performance measurements as discussed below for each component of compensation and is therefore commensurate with actual performance. In structuring variable pay, the Committee seeks to give each executive officer the opportunity to earn more than the median of the total compensation paid to executive officers performing similar job functions at the peer companies for outstanding performance, which can be difficult to achieve. The Committee uses the median level for benchmarking purposes because it believes that is the appropriate level to attract and retain executive officers. Coupled with the opportunity to earn higher amounts commensurate with performance, the Committee believes high performing executives are given appropriate incentives and rewards for performance that results in improved shareholder value.

Although the Committee uses the benchmark standards as its starting point in setting compensation levels, the compensation packages for executive officers may vary materially from the peer group benchmarks based on several factors. Market data, position, tenure, individual and organization performance, retention needs and internal pay equity have been the primary factors considered in decisions to increase or decrease compensation opportunities. Specifically, the Committee sets compensation levels below the benchmark levels for executive officers with relatively less relevant experience, less responsibility, less tenure with the Corporation and/or lower performance ratings. Conversely, if an officer consistently receives favorable performance ratings, accumulates years of service and expertise in relevant areas, has more responsibility and/or has significant other achievements, his or her compensation will typically be above the peer group median. Long-term compensation to executive officers is based on specific performance measurements as discussed below for each component of compensation.

Compensation Structure and Awards for 2011

The Committee periodically reviews the components of the Corporation’s executive compensation program to ensure that pay levels are competitive and that incentive opportunities are effective in attracting and retaining talented employees. Consistent with the Committee’s approach in prior years, the 2011 executive compensation program was based on the following principles:

When setting total compensation for each of the named executive officers, the Committee reviewed in 2011 tally sheets that showed the executive’s total current compensation, including equity and non-equity based compensation. In establishing specific award levels in 2011, the Committee reviewed award amounts granted in past years but it did not adjust amounts or otherwise take into account other award amounts or prior awards that vested because all of the components are targeted at median levels with the opportunity to exceed such levels for superior performance. When the performance is achieved, we believe that the executive officers should be rewarded and that this approach is consistent with achieving sustained value for the shareholders.

Base Salary

The Corporation provides the named executive officers with base salaries to provide minimum compensation for services rendered during the fiscal year. Salary levels for executive officers are typically considered by the Committee annually as part of each executive officer’s performance review as well as upon a promotion or other change in job responsibility, and may be increased or decreased at that time based on: (1) the Committee’s agreement on the individual’s contribution to the Corporation, and (2) changes in median competitive pay levels. The competitive market rate based on the benchmarking standards referred to above and proposed individual salary for each executive are presented by the Chief Executive Officer to the Committee, along with data supporting the recommendations, other than for himself. In 2011, an increase of 2.76% from 2010 base salaries was awarded to each executive officer, other than Mr. Nye, in furtherance of executive management’s efforts to manage costs. The 2011 increase was lower than previous base salary increases given to the executive officers. Base salary in 2011 for executive officers other than Mr. Nye was at approximately the median range of the compensation peer group in 2011.

In assessing the Chief Executive Officer’s base salary for 2011, the Committee approved a base salary of $825,000 for Mr. Nye. This 3.125% increase was awarded based on his excellent achievements as Chief Executive Officer since 2010 in a challenging economic environment. The Committee reviewed base salary data and total compensation data for chief executive officers in the compensation studies described above. It also considered the advice of Towers Watson. Mr. Nye’s base salary and annual incentive bonus compensation for 2011 were below the median range of peers indicated by the compensation studies.

Annual Bonus Compensation

We award annual cash bonuses based on corporate performance objectives and the achievement of individualized targeted goals. This furthers the Corporation’s compensation philosophy in that it encourages superior performance and rewards the achievement of the Corporation’s annual goals. In 2011, under the Corporation’s Executive Incentive Plan, the amount of bonus that an executive could receive was based upon a percentage of that executive’s base salary. In 2011, all of the executive officers participated in the plan, except for Mr. Nye, for whom bonus compensation was awarded outside of the plan.

In determining awards granted under the plan, the Committee first reviews the achievements of the Corporation for the past year as compared to its targeted goals set at the end of the previous year.

The Committee then conducts a comparative review of the individual contributions of each of the executive officers towards achieving these goals. The Committee also considers qualitative measures of performance for the executive officers such as adherence to and implementation of the Corporation’s Code of Ethics and Standards of Conduct, safety, customer satisfaction, and product quality.

The amount awarded to each executive officer is based upon the Committee’s general review of each individual’s achievement of individualized targeted goals, including standard objective measures of financial performance such as earnings, cash flow, and other key sales and production metrics for the Corporation as a whole and for individual business units, and subjective measures, such as the individual’s overall contribution to the Corporation, personal or organizational development and overall effectiveness of the executive. The target for these goals, which is a percentage of base salary depending upon the executive’s position, is set at or about the median level of the executives with comparable responsibilities at the comparable company group. For 2011, the target bonus level set for each of the named executive officers was a percentage of such officer’s base salary: 80% for Ms. Lloyd, Mr. Vaio and Mr. Shephard (pro-rated, based on his September 30, 2011 resignation) and 70% for Ms. Bar. The maximum is 150% of target commensurate with performance at that “stretch” level. There is no threshold since there is no guaranteed bonus if the performance goals are not met.

The objective goals vary by the position of the executive officer. They are established at the beginning of each plan year and are based upon the Corporation’s Long Range Operating Plan, which is set at the end of the previous year. For executives in corporate staff positions, 50% of the determination is made with respect to the Corporation’s performance and 50% is based on the individual’s performance against established objectives. For executives with operating unit responsibility, 40% of the determination is made with respect to the operating unit’s performance, 25% is based on the Corporation’s performance and 35% is based on the individual’s performance against established objectives.

The individualized target goals are tailored for each executive, his or her specific areas of responsibility and the then-current and longer term goals of the Corporation. In addition, achievement of the goals typically is in part dependent on conditions outside the control of each of the named executive officer. For example, we have a strong focus on safety in our business. Regardless of the achievement of other targets, incentive awards are reduced for all employees in the event of any workplace fatality in the Corporation. Similarly, our business may be adversely affected by hurricanes or other weather-related conditions, which could have the result of impeding the achievement of certain performance-based goals.

Although there is substantial uncertainty with respect to achieving the target levels at the time the goals are set and communicated, our named executive officers have a reasonable expectation of receiving a cash incentive award at a level that is near their target level. However, the “stretch” levels remain extremely difficult to obtain and the maximum cash award level has not been achieved in prior periods.

The bonus level for 2011 for the named executive officers was in the range of 49-61% of target as a result of the Corporation’s lower financial performance in 2011 even though the named executive officers achieved near their target levels on the individualized personal goals. The factors that the Committee took into account in determining the Corporation’s performance in 2011 included a detailed assessment of the Corporation’s overall financial performance and each segment’s financial

performance, the Corporation’s continuing successful cost management and automation initiatives in a challenging economic environment, record safety results with the Corporation’s best safety performance and an improvement of 4% in total case incident rate over the prior year’s record low rate, outstanding environmental and regulatory compliance results, continuing achievement of excellent management of working capital, and the successful organic and inorganic growth of the Corporation.

The Chief Executive Officer does not participate in the Corporation’s Executive Incentive Plan and his bonus, if any, is determined at the discretion of the Committee. Generally, his bonus level is approximately 100% of his base salary although there is no specific target for the Chief Executive Officer’s bonus. The Committee did not attempt to set Mr. Nye’s 2011 bonus in any particular relationship to peer compensation survey data. The Committee awarded him an annual incentive bonus of $500,000 for 2011, which was 61% of his base salary, after considering many diverse factors, including the advice of Towers Watson. Consistent with its compensation philosophy that focuses on long-term performance, the Committee considers whether there are factors in addition to quantitative ones that should be taken into account in establishing the overall level of Mr. Nye’s compensation. In this regard, the Committee considered accomplishments that benefit shareholders in the longer term. In subjectively determining the amount of Mr. Nye’s bonus for 2011, the Committee took into account the same type of objective performance measures and qualitative measures, such as the effectiveness and quality of Mr. Nye’s leadership of the Corporation, as it would typically consider for executive officers who receive awards under the plan.

The following achievements were considered by the Committee in determining Mr. Nye’s 2011 bonus:

The Committee also considered the performance of the Corporation as compared to its peers and bonuses awarded to executives in comparable positions in the compensation studies discussed above, as well as the bonuses awarded to the other named executives in 2011.

Because a subjective analysis of performance criteria was used in determining the bonus compensation paid under the Executive Incentive Plan and the bonus compensation paid to Mr. Nye, the bonus compensation does not qualify for the performance-based exception to the $1,000,000 limit on deductibility of executive officer compensation under Section 162(m) of the Internal Revenue Code of 1986.

Performance-Based Stock Purchase Awards

The Incentive Stock Plan is intended to give the named executive officers who participate in the Executive Incentive Plan the opportunity to invest up to 50% of their annual cash bonus to purchase units that are subsequently converted into shares of common stock pursuant to the terms of the plan at a 20% discount from the market price of the Corporation’s common stock on the date the amount of the bonus is determined. Participation in the plan is elective, except that all senior officers of the Corporation are required to invest a minimum of 20% of their cash bonus towards the crediting of units under the plan, except for the Chief Executive Officer who is required to invest a minimum of 35% of his cash bonus towards the crediting of such units. The units generally vest in three years from the date of the award and are distributed in shares of common stock. If an executive officer voluntarily terminates employment before the units vest in three years, the stock units are forfeited and the executive officer receives a cash payment equal to the lesser of the cash that was invested or the fair value of the share units on the day of termination.

The mandatory contribution requirement directly links a portion of executive officer compensation to shareholder returns. The vesting aspect combined with the yearly stock purchase requirement creates continuous overlapping three-year cycles, which encourage executive officer retention and provide a continuous link of a significant portion of executive officer compensation with shareholder return over the long-term to reward these executive officers in line with our shareholders when our stock price increases.

Long Term Incentive Compensation

The Corporation’s long-term compensation in 2011 was equity awards granted in the form of stock options and restricted stock units. When the Committee grants each component of long-term compensation, it first determines the intended cash value of the award based on specific performance metrics described below. It then converts the cash value into an equity award using the closing price of the common stock on the date of award. The equity award is subject to vesting and forfeiture as described below. The target for the awards is the median of comparable companies in the Performance Peer Group and the Committee has designed the awards to give the participants an opportunity to

exceed the median level with high performance. Accordingly, these components of the executive compensation program encourage participants to focus on the long-term performance of the Corporation and provide an opportunity for executive officers to increase their stake in the Corporation. The long-term incentive compensation program delivers more value to executive officers if the value of the Corporation’s stock increases.

LTIP Awards.    The Corporation’s long-term incentive program (LTIP Awards) consists of (1) granting a mix of options and restricted stock units and (2) basing the amount of the award on the performance of the Corporation. The Committee believes that the mix provides better incentives to executive officers than either options or restricted stock units alone. In addition, a change in the accounting rules beginning in 2006 made stock options less attractive because of their impact on our financial statements. Stock options link the compensation provided to the named executive officers with gains realized by the shareholders and therefore serve to confer on recipients an ownership interest in the Corporation. These awards also assist the Corporation in maintaining competitive levels of total compensation. The vesting periods associated with stock options encourage the continued retention of these individuals. The granting of restricted stock unit awards to executive officers continues to provide a motivating form of equity compensation and provides certain advantages over the use of only stock options because restricted stock units have an intrinsic value when granted and executives holding these awards share an immediate downside risk with our shareholders. In addition, restricted stock units permit us to issue fewer shares to deliver the same value, thereby reducing potential dilution.

For each named executive officer, other than the Chief Executive Officer, the Committee derived a target dollar value for this component of compensation based on a review of equity award data in the compensation studies described above and input from Towers Watson. The target is increased each year by an amount equal to the average percentage increase in base pay for each level of officer and relevant subjective considerations, such as a promotion or expanded responsibilities. The maximum award (200%) is a stretch goal based on the Committee’s subjective determination that such level of shareholder value created by the Corporation is outstanding, and for 2011 would be achieved when the Corporation’s return on invested capital is at least 6% higher than the weighted average cost of capital.

In 2011, the Committee considered the Corporation’s performance in light of the severe nature and duration of the recession. The Committee considered the Corporation’s profitability, financial position, growth, regulatory and compliance results, other financial data and other factors relating to the performance of the Corporation and its competitors, including share price performance, operating performance, margin performance, the continued unreduced payment of dividends to shareholders, outstanding cost management, strong capital structure, excellent cash flow results, achievement of a world class safety record, and other factors. It reaffirmed its compensation philosophy of utilizing long-term awards to incentivize executive officers, recognize superior job performance under the extenuating circumstances of the current recession, and retain talented managers. It also considered the significantly lower level of annual bonuses paid starting in 2009, the freezing of base salaries in 2009, and the elimination of certain performance-based restricted stock unit awards to the executive officers granted in previous years as part of the Corporation’s compensation program. The Committee considered advice from Towers Watson that an award based on these metrics was appropriate to reward performance that the Committee viewed as extraordinary during the harsh economic climate.

In light of these considerations, awards were granted in 2011 at 50% of each officer’s target. One-third of the dollar value was then converted to stock options and two-thirds of the dollar value was converted to restricted stock units using the closing price on the date of grant. The one-third stock options to two-thirds restricted stock units bases was determined on a variety of factors, including lattice modeling values for options, median levels of compensation, and a subjective view regarding the appropriate mix of restricted stock units and stock options in light of compensation, incentive and accounting considerations.

In 2011, the Committee awarded Mr. Nye 12,609 options and 6,307 shares of restricted stock units that are subject to vesting, which the Committee believes will align this portion of Mr. Nye’s compensation directly with the Corporation’s performance over the long term. In exercising its discretion for Mr. Nye, the Committee generally follows the same procedures as are followed in determining the amount of annual bonus compensation discussed above. The Committee determined the dollar value for this component of Mr. Nye’s compensation by starting with the median level of long-term compensation identified in the compensation studies reviewed. The Committee then adjusted the amount as it deemed appropriate based on its subjective determination of the Chief Executive Officer’s performance. The dollar value was converted to a mix of one-third stock options and two-thirds restricted stock units, as are the long-term stock option and restricted stock unit awards for the other named executive officers. The award granted was 50% of the target for Mr. Nye.

The stock options granted in 2011 vest ratably over 4 years and the restricted stock units vest on the fourth anniversary of the grant date, in each case in general if the executive is continuously employed from the date of grant through the vesting date. Prior to the exercise of a stock option, the holder has no rights as a shareholder with respect to the shares subject to such option, including voting rights and the right to receive dividends or dividend equivalents. Executives who receive awards of restricted stock units (including restricted stock units discussed below) receive dividend equivalents paid on the shares awarded at the same rate and at the same time as the other shareholders of the Corporation. The value of the receipt of these dividend equivalents is included in the value of the restricted stock unit awards shown in the Summary Compensation Table. We pay these dividend equivalents to remain competitive on compensation because the majority of other comparable companies in compensation surveys pay dividends or equivalents.

Stock-Based Awards Generally.    All stock purchase awards under our Incentive Stock Plan and restricted stock unit awards described above are granted at the Committee’s regularly scheduled meetings in January following the availability of financial results for the prior year, and all LTIP awards are granted in May to enable us to consider current proxy information and compensation surveys for comparable companies. Newly hired executive officers may, subject to the discretion of the Committee, receive an award of restricted stock units as of the date of their hire. The per-share exercise price for all stock options is equal to, and the number of restricted stock units is based on, the New York Stock Exchange closing price of the Corporation’s common stock on the date of the grant. The Committee has never granted stock options with an exercise price that is less than the closing price of the Corporation’s common stock on the grant date nor has it granted options that are priced on a date other than the date the Committee took action to make such grants. The Committee’s schedule is determined several months in advance and the proximity of any awards to earnings announcements or other market events is coincidental.

All of the Corporation’s equity-based award plans have been approved by shareholders.

Ownership Guidelines

The Corporation does not have formal minimum ownership guidelines for the named executive officers but, as noted above, it does generally require that executive officers, other than the Chief Executive Officer, invest a minimum of 20%, and that the Chief Executive Officer invest a minimum of 35%, of each year’s cash bonus award in common stock units of the Corporation that are purchased at a 20% discount to the price on the date of grant through the Incentive Stock Plan, which awards vest generally after three years of additional employment with the Corporation. In addition, a significant portion of the executive compensation program is in the form of equity awards that vest over various periods. There is no required holding period beyond the vesting period. The Committee believes that the equity components of the compensation program appropriately align the interests of executive officers with the interests of our shareholders, as more fully described above.

Perquisites

The Corporation provides named executive officers with perquisites that the Committee believes are appropriate, reasonable and consistent with its overall compensation program to better enable the Corporation to attract and retain superior employees for key positions. The Committee periodically reviews the types and levels of perquisites provided to the named executive officers. The value of each of the named executive officer’s perquisites is included in the annual compensation set forth in the Summary Compensation Table on page 48.

The perquisites provided in 2011 to the named executive officers included personal use of leased automobiles and, for some executive officers, personal use of the Corporation’s plane. The Corporation also provides to executive officers and other employees certain other fringe benefits such as tuition reimbursement, airline club dues, professional society dues, and food and recreational fees incidental to official company functions. The Corporation did not provide country club or dinner club memberships to its executive officers in 2011.

Retirement and Other Benefits

In order to attract, retain and maintain market competitive levels of compensation, we provide retirement and other benefits to the named executive officers and other employees. The benefits under the defined benefit pension plan are more valuable for employees who remain with the Corporation for longer periods, thereby furthering the Corporation’s objectives of retaining individuals with more expertise in relevant areas and who can participate in management development for purposes of executive succession planning. All of the Corporation’s salaried employees are eligible to participate in the following retirement and other plans. The named executive officers participate in the plans on the same terms as the Corporation’s other salaried employees. Additional information regarding these benefits is under the heading Pension Benefit Table below and the accompanying narrative.

Pension Plan.    We have a defined benefit pension plan under which full-time salaried employees of the Corporation who have completed five continuous years of employment with the Corporation, including the named executive officers, earn the right to receive certain benefits upon retirement on a reduced basis at or after age 55 and on an unreduced basis at or after age 62. Retirement benefits are monthly payments for life based on a multiple of the years of service and the

final average eligible pay for the five highest consecutive years in the last ten years before retirement, less an offset for social security. The amount is equal to the sum of (A) plus (B) plus (C) below:

Supplemental Excess Retirement Plan.    We also have a nonqualified restoration plan that covers any employee in the defined benefit pension plan, including the named executive officers, who are highly compensated and whose qualified plan benefit is reduced by Internal Revenue Code benefit or pay limits in Sections 415(b) and 401(a)(17). The plan is based on the same formula as the qualified Pension Plan described above. Benefits under our nonqualified plan are paid from our general assets.

Performance Sharing Plan.    The Performance Sharing Plan is a tax-qualified defined contribution retirement savings plan pursuant to which all salaried employees, including the named executive officers, are eligible to contribute up to the limit prescribed by the Internal Revenue Service on a before-tax basis and up to an additional 17% on an after-tax basis not to exceed a total of 25%. We match 50% of the first 7% of pay that is contributed by employees to the Performance Sharing Plan up to Internal Revenue Service limitations. All contributions as well as any matching contributions are fully vested upon contribution.

Retiree Medical.    Salaried employees who commenced employment with the Corporation prior to December 1, 1999 and who retire with at least 5 years of service are currently eligible for retiree medical benefits for life. Salaried employees who commenced employment with the Corporation between December 1, 1999 and December 31, 2001 and who retire with at least 15 years of service are currently eligible for retiree medical benefits until age 65. Employees share the cost of retiree medical based on their years of service and a predetermined cap on total payments by the Corporation. Employees who commenced employment with the Corporation on or after January 1, 2002 are not eligible for retiree medical benefits. Mr. Nye is not eligible for retiree medical benefits as he commenced employment with the Corporation in 2006.

Medical Insurance.    The Corporation provides an opportunity to all of its salaried employees and the employees’ immediate family to select health, dental and vision insurance coverage. The Corporation pays a portion of the premiums for this insurance for all employees. All employees, including the named executive officers, pay a portion of the premiums depending on the coverage they choose.

Life and Disability Insurance.    The Corporation provides to all of its salaried employees, including the named executive officers, long-term disability and life insurance that provides up to 1.5 times base salary at no cost to the employee. All employees, including the named executive officers, can choose additional coverage and pay a portion of the premiums depending on the coverage they choose. In addition, the Corporation pays an amount equal to one month base salary in the event of death of any active salaried employee.

Housing Allowance and Relocation Costs.    The Corporation provides relocation benefits, including a housing allowance, to certain employees upon their employment with the Corporation or in conjunction with a job relocation or promotion.

Potential Payments Upon Termination or Change of Control

The Corporation has entered into an Employment Protection Agreement with each of the named executive officers that provides for certain payments and benefits upon a qualifying termination of employment following a change of control. The Corporation’s equity-based award plans and retirement plans also provide for certain post-termination payments and benefits. The Committee believes these payments and benefits are important to align the interests of the executive officers with the interests of the shareholders because the agreements will reduce or eliminate the reluctance to pursue potential change of control transactions that may ultimately lead to termination of their employment but otherwise be in the best interests of our shareholders. There are no employment agreements with any employees of the Corporation, including the named executive officers. The Employment Protection Agreement is described on pages 56-58 of this Proxy Statement.

In addition, the Corporation’s Amended and Restated Stock-Based Award Plan, pursuant to which equity-based awards are made to the executive officers, provides that upon the occurrence of a change of control of the Corporation as provided in the Employment Protection Agreements, all time periods for purposes of vesting in, or realizing gain from, any outstanding award under the plan will automatically accelerate.

Tax and Accounting Implications

Section 162(m) of the Internal Revenue Code of 1986 makes certain compensation to the named executives in excess of $1 million non-deductible to the Corporation unless it is based on objectively determined performance criteria pursuant to a plan approved by shareholders. One of the named executive officers received annual compensation exceeding $1 million in 2011 that is not deductible pursuant to Section 162(m).

As part of its role, the Committee reviews and considers the deductibility of executive compensation under Section 162(m). Although the Committee has structured the current compensation program based on various performance criteria as described above, certain aspects of the program do not comply with the other requirements of Section 162(m). The Committee has determined that it is essential in achieving the compensation objectives discussed above to retain the flexibility to exercise subjective judgment in assessing an executive’s performance. The Committee believes that the achievement of the Corporation’s general compensation policies and objectives that are currently in place best serves shareholder interests.

MANAGEMENT DEVELOPMENT AND COMPENSATION COMMITTEE REPORT

The Management Development and Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis beginning on page 30 of this proxy statement. Based on this review and discussion, the Management Development and Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Corporation’s Annual Report on Form 10-K and this Proxy Statement.
