We invite you to attend the annual meeting and vote your shares directly.

You do not need to attend the annual meeting to vote your shares. Instead, you may vote your shares by telephone or through the Internet or you may complete, sign, date, and return the enclosed proxy card in the postage-paid envelope provided. Instructions for voting by telephone or through the Internet can be found on the enclosed proxy card.

The Corporation’s board of directors is soliciting your proxy to encourage your participation in the voting at the annual meeting. This proxy statement provides you with information about each proposal and other matters that you may find useful in voting your shares.

On March 14, 2011, we began mailing this proxy statement and the enclosed proxy card to all stockholders entitled to vote at the annual meeting. We have enclosed with this proxy statement our 2010 annual report to stockholders, which contains detailed information about the Corporation’s activities and financial performance in 2010.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE STOCKHOLDER MEETING TO BE HELD ON APRIL 19, 2011

This proxy statement and the 2010 annual report to stockholders are available at https://materials.proxyvote.com/665859.

VOTING

Who May Vote

Record holders of the Corporation’s common stock at the close of business on February 28, 2011 may vote at the annual meeting. On that date, the Corporation had 242,114,991 shares of common stock outstanding. The shares of common stock held in the Corporation’s treasury will not be voted.

You are entitled to one vote for each share of common stock that you owned of record at the close of business on February 28, 2011. The enclosed proxy card indicates the number of shares you are entitled to vote at the annual meeting.

Voting Your Proxy

Whether or not you plan to attend the annual meeting, we urge you to vote your shares promptly.

If you are a “stockholder of record” (that is, you hold your shares of the Corporation’s common stock in your own name), you may vote your shares by proxy using any of the following methods:

The telephone and Internet voting procedures set forth on the proxy card are designed to authenticate stockholders’ identities, to allow stockholders to provide their voting instructions, and to confirm that their instructions have been properly recorded. If you vote by telephone or through the Internet, you should not return your proxy card.

If you are a “beneficial owner,” also known as a “street name” holder (that is, you hold your shares of the Corporation’s common stock through a broker, bank, or other nominee), you will receive from the record holder voting instructions (including instructions, if any, on how to vote by telephone or through the Internet) that you must follow in order to have your shares voted at the annual meeting.Please note that the rules that guide how brokers vote your stock have changed. Brokers may no longer vote your shares on the election of directors or certain executive compensation matters without your specific instructions. Please return your proxy card so your vote can be counted.

If you own shares of common stock as a participant in The Northern Trust Company Thrift-Incentive Plan (“TIP”), or shares in any other employee benefit plan of the Corporation, you will receive a voting instruction card that covers the shares credited to each of your plan accounts.

Whether you vote by mail, telephone or Internet, your shares will be voted in accordance with your instructions. If you sign, date, and return your proxy card without indicating how you want to vote your shares, the proxy holders will vote your shares in accordance with the following recommendations of the board of directors:

The proxy holders are authorized to vote as they shall determine in their sole discretion on any other business that may properly come before the annual meeting.

Revoking Your Proxy

You may revoke your proxy at any timebefore it is voted at the annual meeting by:

Voting in Person

You may come to the annual meeting and vote your shares in person by obtaining and submitting a ballot that will be provided at the meeting. However, if your shares are held by a broker, bank, or other nominee in street name, to be able to vote at the meeting you must obtain a proxy, executed in your favor, from the record holder of your shares, indicating that you were the beneficial owner of the shares on February 28, 2011, the record date for voting. If you need directions to the annual meeting, please call 312-444-7030.

Householding Information

We are delivering only one annual report and proxy statement to record stockholders who share the same address unless they have notified us that they wish to continue receiving multiple copies. This practice, known as “householding,” reduces duplicate mailings, saves printing and postage costs as well as natural resources and will not affect dividend check mailings. If you wish to receive a separate copy of the annual report or proxy statement, or if you wish to receive separate copies of future annual reports or proxy statements, please call 312-444-7030 or mail a request to the Corporation’s Corporate Secretary at the address indicated on the first page of this proxy statement. We will deliver the requested documents promptly upon your request.

If you and other stockholders of record with whom you share an address currently receive multiple copies of annual reports or proxy statements, or if you hold stock in the Corporation in more than one account and, in either case, you wish to receive only a single copy of the annual report or proxy statement, please contact the Corporation’s transfer agent (Wells Fargo Bank, N.A., Attn: Householding, P.O. Box 64854, St. Paul, MN 55164-0854; Telephone: 877-602-7615) with the names in which all accounts are registered and the name of the account for which you wish to receive mailings.

Quorum and Vote Required for Approval

A quorum of stockholders is necessary to hold a valid meeting. A quorum will exist if a majority of the outstanding shares is present in person or by proxy at the annual meeting. Abstentions and broker non-votes, if any, will be counted as present for purposes of establishing a quorum. A “broker non-vote” will occur when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that proposal and has not received instructions from the beneficial owner.Please note that the rules that

guide how brokers vote your stock have changed. Brokers may no longer vote your shares on the election of directors or certain executive compensation matters without your specific instructions. Please return your proxy card or vote by telephone or through the Internet so your vote can be counted.Inspectors of election appointed for the annual meeting will tabulate all votes cast in person or by proxy at the annual meeting. In the event a quorum is not present at the annual meeting, we expect that the annual meeting will be adjourned or postponed to solicit additional proxies.

The following table indicates the vote required for approval of each item to be presented to the stockholders at the annual meeting and the effect of “withhold” votes, abstentions, and broker non-votes.

Solicitation of Proxies

The Corporation will pay all costs of soliciting proxies. The Corporation has retained Georgeson Inc. to assist with the solicitation of proxies for a fee not to exceed $13,500, plus reimbursement of reasonable out-of-pocket expenses. In addition, we may also use our officers and employees, at no additional compensation, to solicit proxies either personally or by telephone, Internet, letter, or facsimile.

ADMITTANCE TO THE ANNUAL MEETING

Stockholders as of the record date, or their duly appointed proxies, may attend our annual meeting on April 19, 2011, and each may be accompanied by one guest. Registration will begin at 9:30 a.m., and seating will begin at 10:00 a.m. If you attend, please note that you will need an admission ticket or proof of ownership of the Corporation’s common stock to enter the meeting. If you arrive at the meeting without an admission ticket, we will admit you only if we are able to verify that you are a stockholder of the Corporation. Also, you may be asked to present valid picture identification, such as a driver’s license or passport. For safety and security reasons, cameras and recording devices will not be permitted in the meeting.

For stockholders of record, an admission ticket is enclosed. Please bring the admission ticket with you to the meeting.

If your shares of common stock are held by a broker, bank, or other nominee in street name, your admission ticket is the left side of your voting instruction form. If you do not bring the left side of your voting instruction card, you will need proof of ownership to be admitted to the meeting. A recent brokerage statement or letter from a bank or broker is an example of proof of ownership.

ITEM 1—ELECTION OF DIRECTORS

Stockholders will be asked to elect 13 directors at this year’s annual meeting. Set forth below is detailed information with respect to the 13 nominees, 12 of whom are currently serving as directors of the Corporation and its principal subsidiary, The Northern Trust Company (the “Bank”). William D. Smithburg, a director of the Corporation since 1981, will not stand for re-election as a director at the annual meeting. Martin P. Slark, a new director nominee, will stand for election to the vacated seat. Mr. Slark was recommended for consideration as a candidate for director by the Corporation’s Chairman and CEO.

Each of the 13 director nominees has consented to serve as a director if elected at this year’s annual meeting. Each nominee elected as a director will serve until the next annual meeting and until his or her successor has been elected and qualified. If any nominee is unable to serve as a director at the time of the annual meeting, your proxy may be voted for the election of another nominee proposed by the board or the board may reduce the number of directors to be elected at the annual meeting.

The enclosed proxy card provides instructions on how to vote for all nominees or to withhold authority to vote for all or one or more nominees. Under the majority voting policy as set forth in the Corporation’s by-laws, a nominee for director in an uncontested election (such as this year’s election where the only nominees are those recommended by the board of directors) must receive the affirmative vote of a majority of the votes present and voting at a meeting of stockholders. In contested elections, the affirmative vote of a plurality of the votes present and voting will be required to elect a director. The Corporate Governance Guidelines require an incumbent director who fails to receive the affirmative vote of a majority of the votes present and voting in an uncontested election at a meeting of stockholders to submit his or her resignation, with such resignation to be considered by the members of the Corporate Governance Committee and the board other than such incumbent director. In such event, the board of directors will act to accept or reject the incumbent director’s resignation no later than 90 days following the date of the stockholders’ meeting.

The board of directors unanimously recommends that you voteFOR the election of each nominee.

Meetings

The Corporation’s board of directors held six meetings during 2010. All persons who were directors during 2010 attended at least 75% of these meetings and meetings of committees on which they served. The Corporation has a Corporate Governance Guideline that states that all directors are expected to attend the annual meeting of the Corporation’s stockholders. All of the directors attended the 2010 annual meeting of stockholders.

CORPORATE GOVERNANCE

Director Independence

The board of directors has determined that, in its opinion, each person who served as a director of the Corporation in 2010 (including Arthur L. Kelly and Harold B. Smith, who retired from the board of directors on April 20, 2010) and each director nominee for 2011 (other than Frederick H. Waddell, the Chairman, President, and Chief Executive Officer of the Corporation and the Bank) is an “independent” director as defined under applicable NASDAQ rules. The board of directors has adopted categorical standards to assist it in making the annual determinations of independence. These categorical standards are attached as Exhibit A to this proxy statement, and a copy of the categorical standards is available on the Corporation’s website at www.northerntrust.com. In making its determinations of independence, the board considered the criteria for independence set forth in stock exchange corporate governance rules, the categorical standards of independence described above, and all relevant facts and circumstances to ascertain whether there was any relationship between a director or director nominee and the Corporation that, in the opinion of the board, would interfere with the exercise of independent judgment in carrying out the responsibilities of the director, or any material relationship with the Corporation (either directly or as a partner, stockholder, or officer of an organization that has a relationship with the Corporation). The board also considered any transactions, relationships, or arrangements between the Corporation and each director of the Corporation in 2010 (including Mr. Kelly and Mr. H. B. Smith) or director nominee for 2011 that constitute related party transactions under the RPT Policy described below under “—Related Person Transaction Policy.” For 2010, the board considered the following categories and types of transactions, relationships, and arrangements:

The board of directors also considered the following types of services provided by the Corporation or its subsidiaries in the ordinary course of business (as identified by the name of the applicable current director, or director nominee):

Board Leadership Structure

The current leadership structure of the board of directors includes the Chairman and CEO and a Lead Director appointed annually by the Corporation’s independent directors.

The board of directors believes that combining the positions of Chairman and CEO is the most appropriate for the Corporation at this time. Having one person as Chairman and CEO provides unified leadership and direction to the Corporation and strengthens the ability of the CEO to develop and implement strategic initiatives and respond efficiently in crisis situations. The board also believes the combination of the Chairman and CEO positions is appropriate in light of the substantial independent oversight provided by the board of directors.

The board of directors believes that leadership of the independent directors is important. Accordingly, the Corporation’s independent directors designate annually a Lead Director. Mr. Rowe currently serves as the Corporation’s Lead Director.

The Lead Director’s duties are described in the Corporation’s Corporate Governance Guidelines and include, among other things, (a) the authority to call at any time a special meeting of the board or a special executive session of the independent directors and (b) presiding at all regular and any special meetings of the board at which the Chairman is not present, including all regular and any special executive sessions of the independent directors. A copy of the Corporate Governance Guidelines is available on the Corporation’s website at www.northerntrust.com and available in print to any stockholder who requests it in writing from the Corporation’s Corporate Secretary at the address indicated on the first page of this proxy statement.

In addition to the Lead Director, the board of directors has a substantial majority of independent directors. Twelve out of thirteen director nominees are “independent” directors as defined under applicable NASDAQ rules. The Audit Committee, Business Risk Committee, Business Strategy Committee, Compensation and Benefits Committee, and Corporate Governance Committee are composed solely of independent directors, and the Executive Committee, with the exception of Mr. Waddell, is composed of independent directors. Consequently, independent directors directly oversee critical matters and appropriately monitor the Chairman and CEO.

Risk Oversight

The board of directors conducts its risk oversight function through the Audit, Business Risk, Business Strategy, and Compensation and Benefits Committees.

The Audit Committee conducts the Corporation’s management of risks relating to financial reporting and legal component of compliance risk. The Business Strategy Committee oversees the Corporation’s management of strategic risk for the Corporation and its subsidiaries.

The Business Risk Committee conducts the Corporation’s management of risks relating to the business of the Corporation and its subsidiaries in the following categories: credit risk, market and liquidity risk, fiduciary risk, operational risk, and the regulatory component of compliance risk. The Business Risk Committee has approved a corporate risk appetite statement articulating the Corporation’s expectation that risk is consciously considered as part of strategic decisions and in day-to-day activities. The Corporation’s business units are expected to manage business activities consistent with the corporate risk appetite statement. The Business Risk Committee also reviews and

approves the framework by which risk based capital requirements are determined, including the capital adequacy assessment process for the Corporation and its subsidiaries. The entire board of directors reviews the level and adequacy of capital of the Corporation and its subsidiaries. For a further description of the risk management policies and practices of the Corporation’s management, see the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Risk Management” in the Corporation’s 2010 Annual Report to Stockholders.

The Compensation and Benefits Committee, at least annually, conducts a review, with appropriate input of risk management personnel, of management’s assessment of the effectiveness of the Corporation’s incentive compensation arrangements and practices to assess the extent to which such arrangements and practices discourage inappropriate risk-taking behavior by participants and are consistent with the Corporation’s safety and soundness.

The charters for the Audit, Business Risk, Business Strategy, and Compensation and Benefits Committees provide that the committees may meet with the individuals who supervise day-to-day risk management responsibilities of the Corporation and other members of management, consultants or advisors, as each committee deems appropriate.

The Audit, Business Risk, Business Strategy, and Compensation and Benefits Committees consist solely of independent directors.

Executive Sessions

The independent directors of the Corporation met in executive sessions separate from management six times during 2010. The Lead Director or, in his or her absence, another independent director designated by the Lead Director presides at executive sessions of the independent directors.

Corporate Governance Guidelines

The Corporation has had Corporate Governance Guidelines in place since May 2000. These guidelines were most recently revised in February 2010. The Corporate Governance Committee is responsible for reviewing and reassessing, at least annually, the adequacy of the Corporate Governance Guidelines and recommending any changes to the board of directors for its approval. The Corporate Governance Guidelines embody many of the Corporation’s long-standing practices and incorporate new policies and procedures that strengthen its commitment to corporate governance best practices. A copy of the Corporate Governance Guidelines is available on the Corporation’s website at www.northerntrust.com and available in print to any stockholder who requests it in writing from the Corporation’s Corporate Secretary at the address indicated on the first page of this proxy statement.

Management Development and Succession Planning

The Compensation and Benefits Committee oversees executive management and succession planning. Pursuant to the Corporate Governance Guidelines and the charter for the Compensation and Benefits Committee, the Compensation and Benefits Committee conducts an annual management development and succession planning review. All of the Corporation’s directors are invited to participate in this review. Following the review, the Compensation and Benefits Committee makes recommendations concerning management development and succession planning.

In connection with setting the compensation of the Corporation’s Chairman and CEO, as more fully described below in “Compensation Discussion and Analysis,” the Compensation and Benefits Committee and the board of directors review the performance of the Chairman and CEO in light of the Chairman and CEO’s responsibilities to the Corporation, including the development of short-term and long-term strategic plans, goals and objectives, the development of an effective senior management team, positioning of the Corporation for current and future success, and effective communications with all of the Corporation’s constituencies. These criteria, among others, would also be considered by the board of directors in evaluating any successor Chairman and CEO candidates. This management review process also includes a review of other senior employees of the Corporation, with a focus on developing internal candidates for advancement within the Corporation.

In the event of the unexpected death, incapacity, or resignation of the Chairman and CEO, the charter for the Corporate Governance Committee provides that the Corporate Governance Committee will discuss and make a recommendation to the board of directors, after consultation with the Chairman of the Compensation and Benefits Committee, for an appropriate successor. The board of directors also has adopted a Business Continuity Plan that, among other things, delineates a process for appointing an interim Chairman and CEO in the event the Chairman and CEO becomes incapacitated.

Director Nominations and Qualifications

The Corporate Governance Committee is responsible for considering, evaluating, and recommending candidates for director. The Committee will consider persons nominated by stockholders in accordance with the nomination procedures specified in the Corporation’s by-laws or otherwise recommended by stockholders. The Corporation’s by-laws provide that stockholders may propose director nominations only if they give timely written notice, directed to the attention of the Corporation’s Corporate Secretary at the address indicated on the first page of this proxy statement, not less than 120 days prior to the anniversary date of the prior year’s annual meeting. The notice must contain the information required by the by-laws. Stockholders may recommend candidates for director by following the procedures for communicating with directors described below under “Communications with the Board and Independent Directors.”

In its evaluation of director candidates, including persons recommended by stockholders, the Committee considers the factors specified in the Corporation’s Corporate Governance Guidelines to ensure the board has a diversity of perspectives and backgrounds, including the nature of the expertise and experience required for the performance of the duties of a director of a corporation engaged in the Corporation’s business and such matters as: relevant business and industry experience, professional background, age, current employment, community service, and other board service. The Committee also considers the racial, ethnic, and gender diversity of the board in assessing candidates. The Committee seeks to identify, as candidates for director, persons with a reputation for and record of integrity and good business judgment who (i) have experience in positions with a high degree of responsibility and are leaders in the organizations with which they are affiliated, (ii) are free from conflicts of interest that could interfere with a director’s duties to the Corporation and its stockholders, and (iii) are willing and able to make the necessary commitment of time and attention required for effective board service. The Committee also takes into account a candidate’s level of financial literacy, and monitors the mix of skills and experience of the directors in order to assess whether the board has the necessary tools to perform its oversight function effectively. A full listing of the characteristics and qualifications of director candidates considered by the Committee is set forth in the Corporate Governance Guidelines on the Corporation’s website at www.northerntrust.com. Following its

evaluation process, the Committee recommends its director nominees to the full board of directors, and the board makes the final determination of director nominees based on its consideration of the Committee’s recommendation and report.

You are entitled to one vote for each share of common stock that you owned of record at the close of business on February 18, 2013. The proxy card or Notice, as applicable, indicates the number of shares you are entitled to vote at the annual meeting.

Voting Your Proxy

Whether or not you plan to attend the annual meeting, we urge you to vote your shares promptly.

If you are a “stockholder of record” (that is, you hold your shares of the Corporation’s common stock in your own name), you may vote your shares by proxy using any of the following methods:

—

Calling the toll-free telephone number listed on the proxy card (Notice recipients should be sentfirst visit the Internet site listed on the Notice before voting by telephone); or

The telephone and Internet voting procedures set forth on the Notice and the proxy card are designed to authenticate stockholders’ identities, to allow stockholders to provide their voting instructions, and to confirm that their instructions have been properly recorded. If you vote by telephone or through the Internet, you should not return your proxy card.

If you are a “beneficial owner,” also known as a “street name” holder (that is, you hold your shares of the Corporation’s common stock through a broker, bank, or other nominee), you will receive from the record holder, in the form of a Notice or otherwise, voting instructions (including instructions, if any, on how to vote by telephone or through the Internet) that you must follow in order to have your shares voted at the annual meeting.Brokers cannot vote your shares on the election of directors or certain executive compensation matters without your specific instructions.Consequently, it is important that you communicate your voting instructions so your vote can be counted by using any of the following methods:

Voting in Person

You may come to the annual meeting and vote your shares in person by obtaining and submitting a ballot that will be provided at the meeting. However, if your shares are held by a broker, bank, or other nominee in street name, to be able to vote at the meeting you must obtain a proxy, executed in your favor, from the record holder of your shares, indicating that you were the beneficial owner of the shares on February 18, 2013, the record date for voting.

If you need directions to the annual meeting, please call (312) 630-6000.

Householding Information

We are delivering only one annual report and proxy statement (or, as applicable, the Notice) to record stockholders who share the same address unless they have notified us that they wish to continue receiving multiple copies. This practice, known as “householding,” reduces duplicate mailings, saves printing and postage costs as well as natural resources and will not affect dividend check mailings. If you wish to receive separate copies of future proxy materials, please contact Broadridge toll free at 1-800-542-1061, or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, NY 11717. Stockholders who wish to receive a separate set of proxy materials now should contact Broadridge at the same phone number or mailing address and the materials will be delivered to you promptly upon your request.

Quorum and Vote Required for Approval

A quorum of stockholders is necessary to hold a valid meeting. A quorum will exist if a majority of the outstanding shares entitled to vote at the meeting is present in person or by proxy at the annual meeting. Abstentions and broker non-votes, if any, will be counted as present for purposes of establishing a quorum. A “broker non-vote” will occur when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that proposal and has not received instructions from the beneficial owner.Brokers cannot vote your shares on the election of directors or certain executive compensation matters without your specific instructions. Please return your proxy card or vote by telephone or through the Internet so your vote can be counted. Inspectors of election appointed for the annual meeting will tabulate all votes cast in person or by proxy at the annual meeting. In the event a quorum is not present at the annual meeting, we expect that the annual meeting will be adjourned or postponed to solicit additional proxies.

The following table indicates the vote required for approval of each item to be presented to the stockholders at the annual meeting and the effect of “withhold” votes, abstentions, and broker non-votes.

Solicitation of Proxies

The Corporation will pay all costs of soliciting proxies. The Corporation has retained Georgeson Inc. to assist with the solicitation of proxies for a fee of $24,500, plus reimbursement of reasonable out-of-pocket expenses. In addition, we may also use our officers and employees, at no additional compensation, to solicit proxies either personally or by telephone, Internet, letter, or facsimile.

ADMITTANCE TO THE ANNUAL MEETING

Stockholders as of the record date, or their duly appointed proxies, may attend our annual meeting on April 16, 2013. Registration will begin at 9:30 a.m., and seating will begin at 10:00 a.m. If you attend, please note that you will need to bring with you an admission ticket (located on the top portion of the rear side of the proxy card) or proof of ownership of the Corporation’s common stock to enter the meeting. If you arrive at the meeting without an admission ticket, we will admit you only if we are able to verify that you are a stockholder of the Corporation. Also, you may be asked to present valid picture identification, such as a driver’s license or passport. For safety and security reasons, cameras and recording devices will not be permitted in the meeting.

If you are receiving a full set paper copy of our proxy materials and your shares of common stock are held by a broker, bank, or other nominee in street name, your admission ticket is the left side of your voting instruction form. If you do not bring the left side of your voting instruction form, you will need proof of ownership to be admitted to the meeting. A recent brokerage statement or letter from a bank or broker is an example of proof of ownership.

ITEM 1—ELECTION OF DIRECTORS

Stockholders will be asked to elect 12 directors at this year’s annual meeting. Set forth below is detailed information with respect to the 12 nominees, all of whom are currently serving as directors of the Corporation and its principal subsidiary, The Northern Trust Company (the “Bank”).

Each of the 12 director nominees has consented to serve as a director if elected at this year’s annual meeting. Each nominee elected as a director will serve until the next annual meeting and until his or her successor has been elected and qualified. If any nominee is unable to serve as a director at the time of the annual meeting, your proxy may be voted for the election of another nominee proposed by the board or the board may reduce the number of directors to be elected at the annual meeting.

Under the majority voting policy as set forth in the Corporation’s by-laws, a nominee for director in an uncontested election (such as this year’s election where the only nominees are those recommended by the board of directors) must receive the affirmative vote of a majority of the votes present and voting at a meeting of stockholders. In contested elections, the affirmative vote of a plurality of the votes present and voting will be required to elect a director. The Corporate Governance Guidelines require an incumbent director who fails to receive the affirmative vote of a majority of the votes present and voting in an uncontested election at a meeting of stockholders to submit his or her resignation, with such resignation to be considered by the members of the Corporate Governance Committee and the board other than such incumbent director. In such event, the board of directors will act to accept or reject the incumbent director’s resignation no later than 90 days following the date of the stockholders’ meeting.

The board of directors unanimously recommends that you voteFOR the election of each nominee.

In making its determinations of independence, the board considered the criteria for independence set forth in stock exchange corporate governance rules, the categorical standards of independence described above, and all relevant facts and circumstances to ascertain whether there was any relationship between a director or director nominee and the Corporation that, in the opinion of the board, would interfere with the exercise of independent judgment in carrying out the responsibilities of the director, or any material relationship with the Corporation (either directly or as a partner, stockholder, or officer of an organization that has a relationship with the Corporation).

The board also considered any transactions, relationships, or arrangements between the Corporation and each director of the Corporation in 2012 (including Messrs. McCormack and Sosa) or director nominee for 2013 that constitutes a related person transaction under the “Northern Trust Corporation Policy and Procedures with Respect to Related Person Transactions” (the “RPT Policy”) described in the “Related Person Transaction Policy” section below. None of the transactions described below were in an amount which exceeded the greater of $200,000 or 5% of the recipient’s revenues or the greater of $1,000,000 or 2% of the other company’s revenues during the most recent completed fiscal year. For 2012, the board considered the following categories and types of transactions, relationships, and arrangements, some of which are covered by the RPT Policy, and, in each case, determined that they were immaterial and did not affect the independence of any director:

Purchases and sales of goods or services in the ordinary course of business:

Any other related person transaction involving amounts in excess of $120,000 must be approved or ratified by the Audit Committee or the Audit Committee Chair. In considering related person transactions, the Audit Committee or the Audit Committee Chair shall consider all relevant facts and circumstances and shall approve only those related person transactions that are in, or otherwise not inconsistent with, the best interests of the Corporation and its subsidiaries. The RPT Policy also provides that (a) the Corporation shall not hire an immediate family member of an executive officer or director unless the employment arrangement is reviewed and approved by the Compensation and Benefits Committee and (b) no child, stepchild, or parent of an executive officer shall be hired by the Corporation.

In 2012, certain related persons were clients of, and engaged in the types of transactions identified in the bullet points above with, the Corporation and one or more of its subsidiaries. These transactions were undertaken in the ordinary course of business and were made on substantially the same terms (including interest rates and collateral for loan transactions) as those prevailing at the time for comparable transactions with persons not related to the Corporation or the Northern Trust entities involved in the transactions. In addition, loan transactions did not involve more than the normal risk of

collectibility or present other unfavorable features. None of the foregoing transactions or any transactions in which the Corporation or any of its subsidiaries sold or purchased products and services were material to the Corporation or the Northern Trust entities involved in the transactions, and none require disclosure of additional information pursuant to Item 404(a) of Regulation S-K of the Securities Exchange Act of 1934. Any extensions of credit to directors and executive officers of the Corporation were permitted under the provisions of the Sarbanes-Oxley Act of 2002.

Board Leadership Structure

The current leadership structure of the board of directors includes the Chairman and CEO and a Lead Director appointed annually by the Corporation’s independent directors.

The board of directors believes that combining the positions of Chairman and CEO is the most appropriate for the Corporation at this time. Having one person as Chairman and CEO provides unified leadership and direction to the Corporation and strengthens the ability of the CEO to develop and implement strategic initiatives and respond efficiently in crisis situations. The board also believes the combination of the Chairman and CEO positions is appropriate in light of the substantial independent oversight provided by the board of directors.

The board of directors believes that leadership of the independent directors is important. Accordingly, the Corporation’s independent directors designate annually a Lead Director. Mr. Rowe currently serves as the Corporation’s Lead Director.

The Lead Director’s duties are described in the Corporation’s Corporate Governance Guidelines and include, among other things, (a) approving meeting agendas for the board and the nature of information sent to the board, (b) approving board meeting schedules to assure that there is sufficient time for discussion of all board agenda items, (c) the authority to call at any time a special meeting of the board or a special executive session of the independent directors, (d) the authority to add items to the agenda of any regular or special meeting of the board, (e) preparing the agenda for all regular and any special executive sessions of the independent directors, (f) presiding at all regular and special meetings of the board at which the Chairman is not present, (g) presiding at all regular and any special executive sessions of the independent directors, (h) serving as a liaison between the independent directors and the Chairman and CEO, (i) conducting, by means of an interview with each independent director, the independent directors’ annual evaluation of the Chairman and CEO’s performance and then communicating the results to the Compensation and Benefits Committee and to the Chairman and CEO, (j) conducting, by means of an interview with each director, including the Chairman and CEO, the board’s annual self-evaluation of its performance and then providing a summary report to the board, and (k) being available for consultation and direct communication with major stockholders, if they so request. A copy of the Corporate Governance Guidelines is available on the Corporation’s website at www.northerntrust.com and available in print to any stockholder who requests it in writing from the Corporation’s Corporate Secretary at the address indicated on the first page of this proxy statement.

Eleven out of twelve director nominees, including the Lead Director, are “independent” directors as defined under applicable NASDAQ rules. The Audit Committee, Business Risk Committee, Business Strategy Committee, Compensation and Benefits Committee, and Corporate Governance Committee are composed solely of independent directors, and the Executive Committee, with the exception of Mr. Waddell, is composed of independent directors. Consequently, independent directors directly oversee critical matters and appropriately oversee the Chairman and CEO.

Risk Oversight

The board of directors conducts its risk oversight function through the Audit, Business Risk, Business Strategy, and Compensation and Benefits Committees, as well as the full board of directors.

The Audit Committee conducts the Corporation’s management of risks relating to financial reporting and the legal component of compliance risk. The Business Strategy Committee oversees the Corporation’s management of strategic risk for the Corporation and its subsidiaries.

The Business Risk Committee conducts the Corporation’s management of risks relating to the business of the Corporation and its subsidiaries in the following categories: credit risk, market and liquidity risk, fiduciary risk, operational risk, and the regulatory component of compliance risk. The Business Risk Committee has approved a corporate risk appetite statement articulating the Corporation’s expectation that risk is consciously considered as part of strategic decisions and in day-to-day activities. The Corporation’s business units are expected to manage business activities consistent with the corporate risk appetite statement. The Business Risk Committee also reviews and approves the framework by which risk based capital requirements are determined, including the capital adequacy assessment process for the Corporation and its subsidiaries. The entire board of directors reviews the level and adequacy of capital of the Corporation and its subsidiaries. For a further description of the risk management policies and practices of the Corporation’s management, see the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Risk Management” in the Corporation’s 2012 annual report to stockholders.

The Compensation and Benefits Committee, at least annually, conducts a review, with appropriate input of risk management personnel, of management’s assessment of the effectiveness of the Corporation’s incentive compensation arrangements and practices to assess the extent to which such arrangements and practices discourage inappropriate risk-taking behavior by participants and are consistent with the Corporation’s safety and soundness.

The charters for the Audit, Business Risk, Business Strategy, and Compensation and Benefits Committees provide that the Committees may meet with the individuals who supervise day-to-day risk management responsibilities of the Corporation and other members of management, consultants or advisors, as each Committee deems appropriate.

The Audit, Business Risk, Business Strategy, and Compensation and Benefits Committees consist solely of independent directors.

Stockholder Outreach

The Corporation recognizes the importance of stockholder communications to help our investors understand our performance and strategies and to allow our stockholders to express their views on issues important to the Corporation. At the 2012 annual meeting, stockholders voted on stockholder proposals regarding the acceleration of vesting of equity awards in a change in control situation and the independence of the chairman of the board of directors. Both before and after our 2012 annual meeting, we reached out to some of our institutional stockholders to discuss these proposals. Although both proposals failed to receive enough votes to pass, the Corporation took specific action to respond to the concerns raised following the 2012 annual meeting.

With regard to the 2012 stockholder proposal regarding the acceleration of vesting of equity awards in a change in control situation, the Corporation changed its practice of providing single-trigger change in control vesting in its equity compensation awards to “double-trigger” vesting in July 2012.

With regard to the 2012 stockholder proposal regarding the independence of the chairman of the board of directors, the Corporation amended its Corporate Governance Guidelines to expand the responsibilities of the Lead Director as discussed in the “Board Leadership Structure” on page 20.

Given our proactive engagement with stockholders, during 2012 we also reached out to some of our institutional stockholders to invite general comments on governance issues, executive compensation, and other matters. Refer to the “Compensation Discussion and Analysis” section included elsewhere in this proxy statement for a further discussion of the 2013 executive compensation updates.

Executive Sessions

The independent directors of the Corporation met in executive sessions separate from management five times during 2012. The Lead Director or, in his or her absence, another independent director designated by the Lead Director presides at executive sessions of the independent directors.

Corporate Governance Guidelines

The Corporation has had Corporate Governance Guidelines in place since May 2000. These guidelines were most recently revised in July 2012. The Corporate Governance Committee is responsible for reviewing and reassessing, at least annually, the adequacy of the Corporate Governance Guidelines and recommending any changes to the board of directors for its approval. The Corporate Governance Guidelines embody many of the Corporation’s long-standing practices and incorporate new policies and procedures that strengthen its commitment to corporate governance best practices. A copy of the Corporate Governance Guidelines is available on the Corporation’s website at www.northerntrust.com and available in print to any stockholder who requests it in writing from the Corporation’s Corporate Secretary at the address indicated on the first page of this proxy statement.

Management Development and Succession Planning

The Compensation and Benefits Committee oversees executive management and succession planning. Pursuant to the Corporate Governance Guidelines and the charter for the Compensation and Benefits Committee, the Compensation and Benefits Committee conducts an annual management development and succession planning review. All of the Corporation’s directors are invited to and typically all participate in this review. Following the review, the Compensation and Benefits Committee makes recommendations concerning management development and succession planning.

In connection with setting the compensation of the Corporation’s Chairman and CEO, as more fully described below in “Compensation Discussion and Analysis,” the Compensation and Benefits Committee and the board of directors review the performance of the Chairman and CEO in light of the Chairman and CEO’s responsibilities to the Corporation, including the development of short-term and long-term strategic plans, goals and objectives, the development of an effective senior management team, positioning of the Corporation for current and future success, and effective communications with all of the Corporation’s constituencies. These criteria, among others, would also be considered by the

board of directors in evaluating any successor Chairman and CEO candidates. This management review process also includes a review of other senior employees of the Corporation, with a focus on developing internal candidates for advancement within the Corporation.

In the event of the unexpected death, incapacity, or resignation of the Chairman and CEO, the charter for the Corporate Governance Committee provides that the Corporate Governance Committee will discuss and make a recommendation to the board of directors, after consultation with the Chairman of the Compensation and Benefits Committee, for an appropriate successor. The board of directors also has adopted a Business Continuity Plan that, among other things, delineates a process for appointing an interim Chairman and CEO in the event the Chairman and CEO becomes incapacitated.

Director Nominations and Qualifications

The Corporate Governance Committee is responsible for considering, evaluating, and recommending candidates for director. The Committee will consider persons nominated by stockholders in accordance with the nomination procedures specified in the Corporation’s by-laws or otherwise recommended by stockholders. The Corporation’s by-laws provide that stockholders may propose director nominations only if they give timely written notice, directed to the attention of the Corporation’s Corporate Secretary at the address indicated on the first page of this proxy statement, not less than 120 days prior to the anniversary date of the prior year’s annual meeting. The notice must contain the information required by the by-laws. Stockholders may recommend candidates for director by following the procedures for communicating with directors described below under “Communications with the Board and Independent Directors.”

In its evaluation of director candidates, including persons recommended by stockholders, the Committee considers the factors specified in the Corporation’s Corporate Governance Guidelines to ensure the board has a diversity of perspectives and backgrounds, including the nature of the expertise and experience required for the performance of the duties of a director of a corporation engaged in the Corporation’s business and such matters as: relevant business and industry experience, professional background, age, current employment, community service, and other board service. The Committee also considers the racial, ethnic, and gender diversity of the board in assessing candidates. The Committee seeks to identify, as candidates for director, persons with a reputation for and record of integrity and good business judgment who (i) have experience in positions with a high degree of responsibility and are leaders in the organizations with which they are affiliated, (ii) are free from conflicts of interest that could interfere with a director’s duties to the Corporation and its stockholders, and (iii) are willing and able to make the necessary commitment of time and attention required for effective board service. The Committee also takes into account a candidate’s level of financial literacy, and monitors the mix of skills and experience of the directors in order to assess whether the board has the necessary tools to perform its oversight function effectively. A full listing of the characteristics and qualifications of director candidates considered by the Committee is set forth in the Corporate Governance Guidelines on the Corporation’s website at www.northerntrust.com. Following its evaluation process, the Committee recommends its director nominees to the full board of directors, and the board makes the final determination of director nominees based on its consideration of the Committee’s recommendation and report.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

In 2012, the performance and achievements of our named executive officers helped Northern Trust deliver sound financial results in a challenging global economic environment. New business, the integration of recent acquisitions, and our measured approach to managing the business contributed to the Corporation’s continued strong financial position.

Appropriately linking the compensation of our named executive officers to the performance of our business is important to the continued growth and success of Northern Trust. The following chart highlights important considerations in the development, review and approval of our named executive officers’ compensation. Details of each of these highlights are included in the following pages of this Compensation Discussion and Analysis.

2012 Program updates		—  Credited service under the Pension Plan’s Traditional Formula frozen as of March 2012 —  Pension Plan benefits earned beginning in April 2012 are calculated under a reduced Pension Equity Plan (“PEP”) formula for all Pension Plan participants —  “Double-Trigger” Equity Vesting adopted for change in control situations beginning in October 2012 —  Management Performance Plan (“MPP”) amended to clarify that each participant’s performance measures include risk management expectations —  MPP clarified to state expressly that the Committee’s authority to exercise negative discretion includes the discretion to reduce a participant’s award as appropriate to meet all applicable regulatory requirements
2013 Program updates   — Client assets under management grew by 3% in 2010 and have grown at a compound annual growth rate of 7% since 2000. See page 53 for details —   The Corporation continues to maintain its strong balance sheet, including a high quality securities portfolio, with 85% of the total portfolio composed of U.S. Treasury and government sponsored agency securities, Federal Home Loan Bank and Federal Reserve Bank stock, and triple-A rated securities at December 31, 2010, and a high quality loan portfolio with only 1.18% of total loans and leases classified as non-performing at December 31, 2010, which reflects the Corporation’s conservative underwriting standards. —  One-half of long-term incentive compensation awarded as PSUs (up from one-third in 2012) — The Corporation continues to maintain its solid capital position. As of December 31, 2010, the Corporation had a tier 1 capital ratio of 13.6%, a total risk-based capital ratio of 15.6%, and a leverage ratio of 8.8%, each exceeding “well capitalized” levels under federal bank regulatory capital requirements of 6%, 10%, and 5%, respectively. —  One-fourth of long-term incentive compensation awarded as stock options (down from one-third in 2012) —  One-fourth of long-term incentive compensation awards as restricted stock units (“RSUs”) —  Expanded risk-based forfeiture and clawback provisions in certain equity awards beginning in February 2013 —  TIP plan amended effective in January 2013 to discontinue a feature that provided an annual supplemental company contribution of up to 1.5% of “eligible pay” based on attainment of earnings goals — The Corporation continues to invest in its businesses, including by investing $518 million in technology in 2010. 2012 Advisory Vote on Executive Compensation and Adoption of “Double-Trigger” Equity Vesting The Corporation’s executive compensation was approved on an advisory basis by its stockholders at the Corporation’s April 17, 2012 annual meeting. In accordance with its recent practice, the Corporation subsequently engaged in discussions with a number of our institutional stockholders about the design of our executive compensation program and related topics. In particular, the Corporation undertook a review of the Corporation’s treatment of equity and equity-based compensation in connection with a “change in control” of the Corporation, a topic about which stockholders had previously expressed particular concern. After undertaking this review, including an examination of the treatment of equity and equity-based compensation in connection with a “change in control” by members of the Corporation’s peer group (described on pages 41-42), the Compensation and Benefits Committee (as used in this section, the Committee) adopted a “double trigger” approach to vesting equity and equity-based compensation in connection with a change in control of the Corporation. Specifically, this approach means that for equity and equity-based awards granted after 2012, accelerated vesting in connection with a change in control of the Corporation would only occur if either (i) there was a change in control and the award holder experienced a qualifying termination of employment following such change in control, or (ii) there was a change in control and the acquirer refused or was unable assume the existing awards. The Corporation believes that this “double trigger” approach accords with current best practices in this area. Change in control benefits are intended to provide sufficient security so the executive is not distracted from job duties, financially threatened by potential job loss or motivated to act contrary to the best interests of the Corporation and its stockholders prior to, during or after a change in control. Other recent updates to the Corporation’s compensation program are described in the chart entitled “Decisions and Actions” above, under the heading “2013 Program Updates.” 2012 Compensation Decisions for Named Executive Officers In determining total compensation for the named executive officers, the Committee reviews the Corporation’s business performance, the individual’s achievement of objectives, and the total compensation packages paid by the Corporation’s peers (see pages 41-42 of this proxy statement for more details on the peer group). Northern Trust posted solid operating results in 2012, maintained a strong and conservative financial position and continued to grow client assets under custody and management. These results were achieved despite a challenging economic environment that included historically low interest rates and weak global economic conditions. We continued to successfully add new clients and to expand relationships with existing clients, both personal and institutional. This enabled the Corporation to grow the business organically and to offset partially the impact of the economic environment on our revenues. — 2012 net income of $687.3 million increased 14% versus 2011 — 2012 diluted earnings per common share of $2.81 increased 14% versus 2011 — Return on equity of 9.3% in 2012 versus 8.6% in 2011 — Pre-tax profit margin of 25.5% in 2012 versus 23.4% in 2011 Other Highlights Additional highlights of — The Committee considered the Corporation’s executive compensation program include: — Recent Stockholder Endorsement of Executive Compensation. At the Corporation’s 2009 annual meeting of stockholders, stockholders overwhelmingly endorsed the Corporation’s executive compensation program, with approximately 94% of the votes cast in an advisory vote on executive compensation voting in favor of the proposal. — Robust Stock Ownership Guidelines. The Corporation has stock ownership guidelines for named executive officers at or above industry practice, with minimum share ownership levels equal to the lesser of the number of shares having a value equal to ten times base salary or 150,000 shares for the Chairman and CEO and a number of shares having a value equal to five times base salary or 45,000 shares for the other named executive officers. — Management Development and Succession Planning. The Committee conducts an annual management development and succession planning review, reviews the performance of the Chairman and CEO and other senior executives, and makes recommendations regarding succession planning and management development. — Risk Oversight. The Committee annually reviews, with appropriate input of risk management personnel, management’s assessment of the effectiveness of the Corporation’s incentive compensation arrangements and practices to assess the extent to which such arrangements and practices discourage inappropriate risk-taking by such participants and are consistent with the Corporation’s safety and soundness. Executive Compensation Philosophy The Corporation’s executive compensation program is designedperformance relative to attract, motivate,our peers across various measures including growth in assets under management, return on equity, short and retain individuals who will contribute tolong-term total shareholder returns, price/earnings ratio and price/book ratios. Weighing these measures of performance, among others, the Committee determined that the Corporation’s success and the creation of stockholder value. The Corporation emphasizes “total compensation” in establishing its executive compensation levels, with each element of total compensation serving a specific purpose. Total compensation consists principally of base salary, annual cash incentive, and equity compensation (stock options, restricted stock units, and/oroverall performance stock units). Base salary provides a fixed annual level of cash compensation reflecting the executive’s position, experience, and tenure. Annual cash incentive rewards short-term performance, typically reflecting the annual financial performance of the Corporation or its business units plus individual non-financial accomplishments. The Corporation uses equity compensationcompared favorably to ensure that a significant portion of the executive’s total compensation is tied to the longer-term performance of the Corporation’s common stock. In the case of cash compensation and equity compensation alike, the Corporation retains the flexibility to recognize and reward superior corporate, business unit, and individual performance by differentiating the awards made to individual executives. In addition to these elements of annual compensation, the retirement program provides post-employment financial security based on length of service by executives and other employees with the Corporation. The Corporation seeks to further the following core values in the design of its executive compensation program: — Executive compensation should be “performance based.” Total compensation is strongly focused on variable, incentive compensation. For the named executive officers, variable compensation provides the most significant portion of total compensation—typically 80% to 90% of the total for the CEO and other named executives. Incentive compensation reflects various financial and non-financial performance criteria determined by the Compensation and Benefits Committee and evaluated in light of the prevailing economic environment generally, and the environment in the financial services industry particularly. Performance based compensation programs are designed to not encourage excessive risks and to ensure that risk factors are appropriately considered and controlled. — Executive compensation should be “stockholder-aligned.” The Corporation’s executive compensation program emphasizes equity incentive compensation in order to align more sharply the executive officers’ interests with those of the Corporation’s stockholders. Long-term equity compensation provides the majority of the total incentive opportunity for the named executive officers. Equity-based compensation is designed to encourage and motivate executive officers to act as owners with an equity stake in the Corporation, including an incentive to avoid excessive risks. — Executive compensation should be “competitive.” The Corporation’s executive compensation program is designed to compensate individuals at levels that are competitive with executives holding similar positions at financial services organizations with operations comparable to those of the Corporation, adjusted as necessary to reflect the relative financial and operating performance of the Corporation. Peer Group The Committee regularly reviews the composition of the Corporation’s peer group and, as appropriate, updates the peer group to reflect changes among peer companies, industry consolidation and its own evolving global presence. During 2008 and 2009, the Corporation engaged the services of Towers Watson, a globally recognized consulting firm specializing in executive compensation, to conduct a review of its peer group, the current competitive status of its compensation program, and the effectiveness of its compensation policies. As a part of that review, the Corporation established the peer group for 2010 as reflected below.performance. — The peer group includes select companiesCommittee also determined that are representative of a wide array of potentially competitive organizations that generally fall into the following two categories: — Tier 1 companies—Trust and custody banks with whom we compete directly for talent in virtually all lines of business on a global basis; U.S. banks with whom we may compete for talent and that are similar in size; and non-bank financial firms that are competitors in specific business lines. — Tier 2 companies—Money center or other large U.S. banks with business units that directly compete againstCorporation’s performance compared favorably to the Corporation for customers and talent as well as global financial companies that are competitors, both in the U.S. and globally. The Corporation’s peer group companies are as follows: Tier 1 Companies Tier 2 Companies U.S. Banking Companies Including Trust and Custody Banks Asset Management and Brokerage Companies Large U.S. Bank Competitors Global Competitors The Bank of New York Mellon Corporation Ameriprise Financial, Inc. Bank of America Corporation Barclays PLC Comerica Incorporated BlackRock, Inc. Citigroup Inc. Credit Suisse Group AG Fifth Third Bancorp Franklin Resources, Inc. JPMorgan Chase & Co.

Profitability and returns were compared based on pre-tax margin and return on equity. — Consistent with the Corporation’s philosophy of aligning pay with performance, the Committee determined that the Chairman and CEO’s total pay should compare favorably with the median compensation among the Corporation’s peer companies relative to size, financial results, and shareholder returns. Chairman and CEO To determine the size of each element in the Chairman and CEO’s total compensation package, in addition to the business results listed above, the Committee considered a variety of performance factors including: Financial Performance 2012 Financial Results —    Net income was $687.3 million in Tier 1 and Tier 2 are included2012, an improvement of 14% from $603.6 million in 2011. —    Our Driving Performance initiative was announced in early 2012, delivering significant pre-tax income benefits in the Keefe, Bruyetteyear and is on track to reach our target of $250 million in pre-tax income improvement in 2013. —    Our pre-tax profit margin improved to 25.5% in 2012 from 23.4% in 2011. Return on Equity —    Northern Trust’s return on equity was 9.3% in 2012, an increase from 8.6% in 2011 and represents progress toward our long-term target of 10-15%. Capital planning —    The Corporation’s capital ratios are well above the ratios that are a requirement for regulatory classification as “well capitalized”. —    In 2012, the Federal Reserve did not object to the Corporation’s capital plan. —    Our capital actions for the year included an increase in the quarterly dividend to $0.30 per share and the repurchase of 3.5 million common shares, returning almost $450 million in capital to our shareholders. Risk Management —    There were no material changes to our risk profile in 2012. The quality of our balance sheet remained strong as was our liquidity position at both the corporate and bank levels. Strategic Development New Business Development —    Assets under management rose 14% while assets under custody rose 13%. Our growth in clients is broad and diversified across our businesses, services and geographies. Corporate Development / Acquisitions —    Completed the integration of Bank of Ireland Securities Services and hedge fund servicer Omnium LLC (from Citadel LLC). Organizational Development Leadership Development —    Recent appointments to our leadership team, including senior roles in Human Resources, Audit, and Corporate & Woods, Inc. Bank Index (“KBW Index”),Institutional Services, demonstrate a market-capitalization-weighted bank stock indexsolid succession plan. We continue to maintain a strong group of leaders in the succession pipeline. Additionally, the Committee considered the Chairman and CEO’s success in achieving his individual non-financial performance objectives related to leadership, compliance, client service, corporate social responsibility, employee relations, communication, ethics and diversity, and development of senior officers. Weighing these performance factors and objectives collectively, the Committee determined that total compensation for the Chairman and CEO should compare favorably with the median compensation among the Corporation’s peer companies, relative to size, financial results, and shareholder returns. Base Salary During its February 2012 meeting, the Committee determined that the Chairman and CEO’s salary should remain unchanged. This decision was guided by competitive market data from peer group companies, as well as the Chairman and CEO’s performance and tenure in the position. At its February 2013 meeting, the Committee determined that the Chairman and CEO’s salary should remain unchanged, although it is modestly lower than the 2012 salary of the Corporation’s peer group, adjusted for size, financial results, and shareholder returns. Short-Term Annual Cash Incentive Under the provisions of the MPP, the reported earnings of $687.3 million in 2012 provided for a maximum funding opportunity for the Chairman and CEO of $4,123,800. Additionally, based on the peer group market data, the Committee determined that the peer group median cash incentive level, adjusted for size, financials, and returns, was slightly below $2,000,000. Taking into consideration the limits set forth in the MPP, the available competitive market data, as well as the performance measures and individual objectives as listed above, the Committee determined the Chairman and CEO’s actual cash incentive award to be $2,000,000 for 2012. Compared to the 2011 cash incentive award of $1,600,000, the year over year increase in the Chairman and CEO’s 2012 award reflected that the Corporation’s earnings for 2012 were up 14% relative to 2011. In addition, ROE improved to 9.3% from 8.6% and growth in new business was strong. Long-Term Incentive In determining the total long-term incentive award for the Chairman and CEO, the Committee took into account the Corporation’s performance measures listed above, as well as the median and total compensation packages paid by the Corporation’s peers, adjusted for size, financial results, and shareholder returns. Based on these factors, as well as our objective to make long-term compensation the most significant component of overall compensation, the Committee set the Chairman and CEO’s long-term incentive compensation award in respect of 2012 performance, granted in 2013, at $6,650,000, which was above the 2012 long-term compensation level reported by our peer companies, and lower than the Chairman and CEO’s long-term incentive award of $7,000,000 made in 2012 for 2011 performance. As illustrated in the following chart, the Chairman and CEO’s compensation increased less than 1% from 2011 to 2012.   Salary and Incentive Compensation1           Name         Annual Compensation                       Incentive Compensation3           Year     Salary2     Cash     PSUs     Stock Options4     RSUs     Long- term Cash     Total   Frederick H. Waddell       2012      $ 975,000      $ 2,000,000      $ 3,325,000      $ 1,662,500      $ 1,662,500      $ 0      $ 9,625,000        2011      $ 956,250      $ 1,600,000      $ 2,333,333      $ 2,333,333      $ 0      $ 2,333,334      $ 9,556,250    1The Salary and Incentive Compensation chart above is an overview of the Committee’s salary, cash incentive, stock options, RSUs, PSUs and deferred cash compensation decisions for the Chairman and CEO with respect to 2012 and 2011. The long-term incentives described for 2012 were in fact made in 2013 in respect of 2012 performance and thus do not appear in the Summary Compensation Table on page 60 of this proxy statement. Further details of the Chairman and CEO’s compensation in 2012 can be found in the Summary Compensation Table on page 60 of this proxy statement. 2 Actual salary paid in that year. 3Incentives earned for performance in that year but paid/granted in the following year (e.g. stock options listed for 2011 were granted in 2012 based on performance in 2011). The value of these awards is listed in the Summary Compensation Table for the year of grant pursuant to SEC rules. 4Northern Trust’s policies and internal valuation methodology treat stock options as equal to one-third of the grant price. A different valuation methodology is required to be used in the Summary Compensation Table pursuant to the SEC rules. The mix of total compensation for our Chairman and CEO, as illustrated in the chart below, demonstrates our emphasis on variable compensation, with significant focus on long-term incentive components. Other named executive officers In determining total compensation for the named executive officers, the Committee reviews the Corporation’s business performance, the individual’s achievement of objectives, and the total compensation packages paid by the Corporation’s peers (see pages 41-42 of this proxy statement for more details on the peer group). The Committee considered a variety of performance factors for each individual, as indicated below: William L. Morrison Mr. Morrison is the Corporation’s President and Chief Operating Officer. To determine the size of each element in Mr. Morrison’s total compensation package, in addition to the business results listed above (see pages 32-33), the Committee considered a variety of performance factors including: — Net income was $687.3 million, an increase of 14% from 2011. — Return on equity improved in 2012 to 9.3% from 8.6% in 2011 and represents progress toward our long-term target of 10-15%. — Our Driving Performance initiative was announced in early 2012, delivering significant pre-tax income benefits in the year and is on track to reach our target of $250 million in pre-tax income improvement in 2013. — Both our C&IS and PFS business units had strong new business in 2012. — We successfully completed the integration of two acquisitions made in 2011. Additionally, the Committee considered Mr. Morrison’s success in achieving his individual non-financial performance objectives related to leadership, compliance and risk management, client service, employee relations, communication, ethics and diversity, and development of senior officers. At its meeting in February 2013, based on performance, his tenure in the role, and updates in the competitive salary market data among the Corporation’s peer group companies, the Committee chose to increase the base salary for Mr. Morrison, by $100,000. Based on the target and limits set forth in the MPP for Mr. Morrison, as well as the Corporation’s performance and achievement of Mr. Morrison’s individual objectives, the Committee set a cash incentive of $1,000,000 for Mr. Morrison. In determining the total long-term incentive award made to Mr. Morrison in 2013 in respect of 2012 performance (which does not appear in the Summary Compensation Table on page 60 of this proxy), the Committee took into account the Corporation’s performance, as well as the total compensation levels among the Corporation’s peers, adjusted for size, financial results, and shareholder returns. Based on these factors, the Committee set a long-term award of $3,350,000 for Mr. Morrison. Michael G. O’Grady Mr. O’Grady is the Corporation’s Executive Vice President and Chief Financial Officer. He heads the Corporate Financial Management Group. To determine the size of each element in Mr. O’Grady’s total compensation package, in addition to the business results listed above (see pages 32-33), the Committee considered a variety of performance factors including: — In 2012, financial strength remained a hallmark of the Corporation, with asset quality in the loan, liquidity and securities portfolios contributing to sound credit ratings. — Our 2012 capital plan was not objected to by the Federal Reserve, which allowed the Corporation to return almost $450 million in capital to shareholders through an increase in the performance graph presentedquarterly dividend and the repurchase of 3.5 million common shares. — The Driving Performance initiative announced in early 2012 delivered significant pre-tax income benefits in 2012 and is on track to reach our target of $250 million in pre-tax income improvement in 2013. — The Corporation maintained an active investor relations program in 2012, which encompassed conference participation in Chicago, New York and London, as well as numerous meetings and conference calls held with analysts and investors. The Committee also considered Mr. O’Grady’s success in achieving his individual non-financial performance objectives related to leadership, compliance and risk management, employee relations, communication, ethics and diversity, and development of senior officers. At its meeting in February 2013, based on updates in the competitive salary market data among the Corporation’s peer group companies, the Committee chose to increase the base salary for Mr. O’Grady by $25,000. Based on the target and limits set forth in the MPP for Mr. O’Grady, as well as the Corporation’s performance and achievement of Mr. O’Grady’s individual objectives, the Committee set a cash incentive of $750,000 for Mr. O’Grady. In determining the total long-term incentive grant made to Mr. O’Grady in 2013 in respect of 2012 performance (which does not appear in the Summary Compensation Table on page 60 of this proxy), the Committee took into account the Corporation’s performance, as well as the total compensation levels among the Corporation’s peers, adjusted for size, financial results, and shareholder returns. Based on these factors, the Committee set a long-term award of $2,000,000 for Mr. O’Grady. Steven L. Fradkin Mr. Fradkin is President of the Corporate & Institutional Services business unit (“C&IS”). To determine the size of each element in Mr. Fradkin’s total compensation package, in addition to the business results listed above (see pages 32-33), the Committee considered a variety of performance factors including: — C&IS net income was $289.2 million in 2012 compared with $294.1 million in 2011. — C&IS assets under custody increased 12% in 2012 and equaled $4.4 trillion at December 31, 2012. — In 2012, C&IS successfully completed the integration of two acquisitions made in 2011 and achieved record new business for the year. The Committee also considered Mr. Fradkin’s success in achieving his individual non-financial performance objectives related to leadership, compliance and risk management, client service, employee relations, communication, ethics and diversity, and development of senior officers. At its meeting in February 2013, based on updates in the competitive salary market data among the Corporation’s peer group companies, the Committee chose to leave the base salary for Mr. Fradkin unchanged, resulting in a salary level for Mr. Fradkin that remained consistent with salaries for similar positions among the Corporation’s peer group. Based on the target and limits set forth in the MPP for Mr. Fradkin, as well as the Corporation’s performance and achievement of Mr. Fradkin’s individual objectives, the Committee set a cash incentive of $800,000 for Mr. Fradkin. In determining the total long-term incentive grant made to Mr. Fradkin in 2013 in respect of 2012 performance (which does not appear in the Summary Compensation Table on page 60 of this proxy), the Committee took into account the Corporation’s performance, as well as the total compensation levels among the Corporation’s peers, adjusted for size, financial results, and shareholder returns. Based on these factors, the Committee set a long-term award of $2,000,000 for Mr. Fradkin. Jana R. Schreuder Ms. Schreuder is President of the Personal Financial Services business unit (“PFS”). To determine the size of each element in Ms. Schreuder’s total compensation package, in addition to the business results listed above (see pages 32-33), the Committee considered a variety of performance factors including: — PFS net income was $371.7 million in 2012 compared with $256.2 million in 2011. — PFS assets under management increased 14% in 2012 and equaled $197.7 billion at December 31, 2012. — New business in PFS was strong in 2012 and Northern Trust was named Best Private Bank in the Corporation’s 2010 Annual ReportU.S. by the Financial Times Group for the fourth consecutive year. The Committee also considered Ms. Schreuder’s success in achieving her individual non-financial performance objectives related to leadership, compliance and risk management, client service, employee relations, communication, ethics and diversity, and development of senior officers. At its meeting in February 2013, based on updates in the competitive salary market data among the Corporation’s peer group companies, the Committee chose to leave the base salary for Ms. Schreuder unchanged, resulting in a salary level for Ms. Schreuder that remained consistent with salaries for similar positions among the Corporation’s peer group. Based on the target and limits set forth in the MPP for Ms. Schreuder, as well as the Corporation’s performance and achievement of Ms. Schreuder’s individual objectives, the Committee set a cash incentive of $825,000 for Ms. Schreuder. In determining the total long-term incentive grant made to Ms. Schreuder in 2013 in respect of 2012 performance (which does not appear in the Summary Compensation Table on page 60 of this proxy), the Committee took into account the Corporation’s performance, as well as the compensation levels among the Corporation’s peers, adjusted for size, financial results, and shareholder returns. Based on these factors, the Committee set a long-term award of $2,000,000 for Ms. Schreuder. Guiding Principles for Executive Compensation Northern Trust’s compensation philosophy is to attract, motivate and retain talent, including executive-level talent who will contribute to our long-term success. With the goals of solid long-term financial performance and creating long-term stockholder value, Northern Trust’s executive compensation program and compensation decisions are framed by four core values. Linked to Long-Term Performance Northern Trust’s executive compensation program is strongly focused on incentive compensation, which is intended to help drive long-term financial performance. Currently, 80% to 90% of each named executive officer’s total pay opportunity consists of variable compensation. Short-term cash and long-term incentive awards, as described in this proxy, are based on each named executive officer’s performance. The Committee determines and approves annual cash incentives for Northern Trust’s named executive officers under the provisions of the stockholder-approved MPP. Aligned with Stockholder Interests Northern Trust’s executive compensation program is designed to align the interests of the named executive officers with those of its stockholders by tying a significant portion of an executive’s total compensation to the longer-term performance of the Corporation’s common stock. Long-term incentive compensation is the most significant component of overall compensation as it generally provides the majority of named executive officers’ total target compensation. The emphasis on long-term multi-year vesting schedules applied to these incentives contributes to continuity and stability within the Corporation’s executive leadership and encourages executives to act as owners with a tangible stake in Northern Trust. The following chart demonstrates how the value of Northern Trust’s equity-based compensation awarded over the past five years, including 2012, has been impacted by changes in our stock price. Supporting the alignment with stockholders’ interests, Northern Trust has a long-standing practice of emphasizing stock ownership and maintaining robust stock ownership guidelines for named executive officers at or above industry practice. Stock Ownership Guidelines Northern Trust maintains formal stock ownership guidelines for named executive officers with minimum ownership levels as shown in the following chart: Stock Ownership Guidelines for Named Executive Officers Chairman and CEO Expected to Stockholders. Usemaintain minimum share ownership levels to a value of Peer Group Dataten times base salary President and Chief Operating Officer or Vice Chairman The Corporation is Expected to maintain minimum share ownership levels to a leading providervalue of asset servicing, fund administration, asset management, fiduciaryseven times base salary Other Named Executive Officers Expected to maintain minimum share ownership levels to a value of five times base salary It is expected that each named executive officer will meet the minimum ownership level not later than five years from the date the named executive officer becomes a member of a particular covered group. Until such time as any named executive officer meets the minimum ownership level requirement, he or she is expected to retain 100% of the net, after-tax shares received from share distributions or stock option exercises. The calculation of shares of common stock includes those that are: — Purchased on the open market — Owned jointly with or separately by spouse and banking solutions for corporations, institutions, families,children — Held through the Thrift Incentive Plan — Obtained through stock option exercises but not including unexercised stock options and individuals worldwide. In addition, the Corporation has a significant global presence with an increasing portionstock award distributions — 50% of its client baseunvested (or vested but not yet distributed) RSUs, PSUs, stock awards and employee population located abroad.deferred stock units — The character and relative size50% of the Corporation’s businesses make it challenging to identify any definitive, single group of companies as peers for compensation purposes. The global scope and prominence of our primary business lines means that few regional banks of our size are direct or consistent business or talent competitors. Instead, most direct competitors are either significantly larger institutions, smaller standalone entities that compete with one or more of our business lines, or global financial firms located outside of the U.S. Nevertheless, the Corporation believes that the companies listeddeferred long-term cash incentives which may be distributable in the aboveform of stock As of December 31, 2012, the Chairman and CEO and each other named executive officer met or exceeded Northern Trust’s stock ownership guidelines. Consistent with those guidelines, Mr. O’Grady, who commenced employment with the Corporation in August 2011, has five years from that date in which to reach the applicable share ownership threshold set forth in the chart above. Positioned Competitively in the Marketplace The Corporation believes a competitive executive compensation program is key to attracting, retaining and motivating the best executive talent. Therefore, the Committee evaluates the competitiveness of Northern Trust’s named executive officer compensation program against a peer group that reflects key trust and custody banks, as well as certain other U.S. banking organizations. This peer group, used for assessing the competitiveness of named executive officer pay, specifically excludes certain other direct competitors whose size or scope are significantly larger and might distort the appropriate pay comparisons. The combination of the character and relative size of the Corporation’s businesses makes it challenging to identify any definitive, single group of companies as peers for compensation purposes. However, Northern Trust established the peer group based in part on data and analysis provided by Towers Watson, an independent compensation consultant. The peer group is identified below. Northern Trust Named Executive Officer 2012 Peer Group These companies are used for market assessment of compensation for the Chairman and CEO and the other named executive officers. This peer group fairly represent its principal competitionreflects: —      Trust and custody banks that Northern Trust directly competes against for executiveglobal talent in virtually all lines of business: The Bank of New York Mellon Corporation and State Street Corporation —      Other U.S. banks that vary in size and are an appropriate group of companies against whichused to gaugeevaluate the competitiveness of the Corporation’sour executive compensation program. The Bank of New York Mellon Corporation Comerica Incorporated Fifth Third Bancorp KeyCorp The PNC Financial Services Group, Inc. State Street Corporation SunTrust Banks, Inc. U.S. Bancorp Wells Fargo & Company The Corporation believes that this group of peer companies fairly represents a wide range of our competitors and certain other U.S. banking organizations and is an appropriate group of companies against which Northern Trust can assess the competitiveness of the Corporation’s executive compensation program for the named executive officers. The Committee regularly reviews the composition of Northern Trust’s peer group and makes updates based on changes within the peer group companies, industry consolidation and the Corporation’s own evolving global presence. For both 2011 and 2012, the Corporation utilized the same targeted group of peer companies, as listed above, in order to focus on key trust and custody banks, as well as certain other U.S. banking organizations. The Committee believes that the peer group allows it to gauge the competitiveness of our named executive officers compensation program against our peers. Northern Trust does not use peer compensation data to set precise pay levels by position. Rather, the peer data and data provided by compensation consultants are used to validate relative competitive pay for our named executive officers. Discourage Inappropriate Risk-Taking As noted above, the Corporation is involved in an ongoing assessment of its incentive compensation program in connection with the Federal Reserve’s review of incentive compensation arrangements at Large Complex Banking Organizations. Northern Trust concluded its compensation arrangements did not inappropriately encourage excessive risk-taking, in part because the Corporation is not involved with many of the lines of business that have often exposed other financial institutions to excessive risk-taking, such as origination or securitization of sub-prime mortgage loans or significant proprietary derivatives trading. Northern Trust actively monitors employees to ensure that they work within established risk frameworks and limits. To reinforce the peer group reflect a wide rangeimportance of absolute pay levels and pay practices. Because of this, it is impractical to establish a single targeted market position or to utilize peer-based financial measures in compensation. Rather, the Corporation targets totalincorporating risk management into our compensation at points in this range that are appropriate based on the Corporation’s size, scope, and business model, and that are consistent with the Corporation’s financial business plan. Using information from this group, the Corporation targets a mix of base salary, cash incentives,framework, we utilized PSUs and long-term equity compensation that balances competitive practices with the Corporation’s overall philosophy and strategy. To accomplish these objectives, the Corporation has established Total Compensation Guidelines (“Committee Guidelines”)cash in 2012. PSUs, which contain performance hurdles for members of its Management Group, including the named executive officers and are payable in shares if these hurdles are attained, incorporate performance and discourage inappropriate risk-taking. Long-term cash, which may be settled in cash or stock, is deferred for otherthree years and is subject to forfeiture upon the occurrence of certain risk-based events. Furthermore, a substantial portion of the compensation of senior level officers. The Committee Guidelines reflectmanagement is in the form of long-term equity, including options, that vests over a multi-year Risk Management Expectations To align with Federal Reserve regulations for the financial industry, Northern Trust provided guidance to its covered employees—including named executive officers—about Northern Trust’s risk management expectations and the incentive adjustments that may be made to awards for those who expose the Corporation to excessive risk. It is our expectation that all executive officers appropriately understand the Northern Trust risk management framework and how the framework reinforces the Corporation’s strategycompensation strategy. period and has an inherent risk adjustment factor based on Northern Trust’s share value. Consistent with the Corporation’s risk-mitigation strategies for the level and relative mix of base salaries, cash incentives, and equity-based compensation. However, the Committee Guidelines also are structured to afford the Committee flexibility in meeting evolving talent requirements in a global marketplace. The Committee Guidelines are considered, along with various other financial and non-financial factors, when determining individual pay actions. In addition to the Committee Guidelines, competitiveits compensation dataprograms, long-term compensation for specific positions or groups of positions may be considered from time to time. For purposes of comparing pay levels of the CEO or other2012 for named executive officers incorporated clawback provisions that deter certain types of conduct, including conduct that could affect the Committee relies on data from the Tier 1 companies only. Use of Discretion and Other Factors in Pay Decisions The exercise of discretion by the Committee in determining the various elements of compensation also is an important featureaccuracy of the Corporation’s compensation philosophy. The Corporation believes it is important that the Committee has sufficient flexibility to respond to (i) the Corporation’s unique circumstances; (ii) prevailingfinancial statements. Clawback provisions were further enhanced for certain forms of 2013 long-term compensation. In order to address the Federal Reserve’s view that stock options can induce more risk-taking than other types of equity based compensation, in 2012 Northern Trust reduced the proportion of its long-term incentive awards composed of stock options and replaced a portion of those awards with PSUs and long-term cash, which are viewed as less likely to induce inappropriate levels of risk-taking. In 2013, Northern Trust made additional changes to the composition of its long-term incentive awards for the named executive officers to further reinforce performance and the link between compensation and increasing shareholder value. Beginning in 2013, PSUs, which carry vesting provisions that incorporate performance and discourage inappropriate risk-taking, will represent one-half of long-term incentive compensation, up from one-third in 2012; stock options will represent one-quarter of the total value of each named executive officer’s long-term incentive compensation, down from one-third in 2012; and RSUs, which include expanded risk-based forfeiture and clawback provisions, will represent one-quarter of long-term incentives. The Committee annually assesses with input from risk management personnel the effectiveness of Northern Trust’s incentive compensation and the extent to which such arrangements and practices discourage inappropriate risk-taking. We expect to continue to monitor and, if necessary, revise our incentive compensation program to ensure that it appropriately balances the desires of stockholders, the needs of the business and risk concerns. Determining Awards Role of the Committee During its February meeting, the Committee determines the appropriate level of executive compensation and each element of cash and equity compensation for all named executive officers. The Committee makes executive compensation decisions after careful review and analysis of appropriate performance information, as well as historical and market compensation data. The Committee considers all elements of Northern Trust’s executive compensation program holistically rather than each compensation element individually. The Committee also considers the impact that compensation decisions may have on the potential values of other pay and benefit programs. While performance in non-financial areas may or may not directly affect the specific financial metrics for a particular year, the Committee has the discretion to reward extraordinary individual performance in non-financial areas that are important to long-range growth and enhancement of stockholder value. This flexibility allows the Committee to best reflect: — Northern Trust’s business model and strategy — Prevailing market trends; (iii) the rapidlytrends — Rapidly evolving financial and regulatory environment in which the Corporation operates; (iv) the Corporation’s use of cross-functioning with respect to — Cross-functioning executive assignments and cross-training as a matter of executive development and succession planning; and (v) risk — Risk management objectives. The Corporation also believes it is in the best interest of the Corporation and its stockholders that the Committee have sufficient discretion to recognize and reward extraordinary individual performance in non-financial areas that may or may not directly affect the Corporation’s achievement of specific financial metrics for a particular year, but are nevertheless important to long-range growth and the enhancement of stockholder value. The Committee determines total compensation and each element of cash and equity compensation for all named executive officers of the Corporation. In determining the compensation of each named executive officer, the Committee relies upon the following types of information: — Committee Guidelines—Based on peer compensation information and guidance of outside expert consultants, the Committee has established a guideline pay range for each element of cash and equity compensation. The Committee reviews and updates the Committee Guidelines periodically, based in part, on its review of comparative compensation information concerning the peer group listed above. The Committee Guidelines specify a guideline base salary for the Corporation’s Chairman and CEO and the other named executive officers, together with guideline ranges of annual cash incentive and equity compensation opportunities expressed as a percentage of base salary. The range of total compensation and range of each pay element set forth in the Committee Guidelinesobjectives generally reflects a balance between competitive pay practices relative to the peer group as well as consideration of internal pay equity among comparable executive officer positions and the Corporation’s philosophy regarding the relative mix of cash and equity compensation desired. The Committee also evaluates the performance of the Chairman and CEO against his objectives for the past year as stated on pages 33-34. Role of the Chairman and CEO As part of the Committee’s compensation review and approval process, the Committee receives recommendations from the Chairman and CEO on the total compensation packages for each of Northern Trust’s named executive officers, other than his own. The Chairman and CEO’s evaluations of the other named executive officers are based on performance against the past year’s performance expectations, initially formulated by the Chairman and CEO at the beginning of the performance period. These performance expectations are comprised of a mix of objective and subjective factors, which are not formulaically weighted or scored. With input from the Corporation’s Chief Risk Officer, the Chairman and CEO also evaluates each named executive officer’s performance with regard to business unit risks and individual adherence to risk and compliance policies and procedures. The Chairman and CEO presents recommendations in a report at the Committee’s February meeting. The Committee gives substantial weight to the recommendations of the Chairman and CEO, but retains the ultimate oversight and responsibility to make modifications to the total compensation package and individual compensation elements. The Committee provides the final approval of the compensation of each named executive officer. The Committee may grant additional long-term incentive awards during other times of the year to newly hired or newly promoted named executive officers based on the recommendation of the Chairman and CEO. In isolated cases, the Committee may grant additional long-term incentive awards for retention purposes. No such retention awards were granted to named executive officers in 2012. Role of Human Resources The Corporation’s Human Resources Department assists the Committee in making executive compensation decisions, including collecting and providing the Committee current and historical compensation data. Additionally, the Head of Human Resources attends and participates in all Committee meetings. The Human Resources Department also assists the Chairman and CEO in formulating the recommendations for compensation of all other named executive officers other than the Chairman and CEO. The Human Resources Department provides historical and current market data for executive pay in the industry, information concerning the historical and current compensation of named executive officers, and the comparison of stock ownership measured against stock ownership guidelines approved by the Committee. Role of Aon Hewitt The Committee has retained Aon Hewitt as its human resources consulting firm for matters pertaining to executive compensation. The Committee confers with Aon Hewitt to ensure that decisions and actions are consistent with stockholders’ long-term interests and compensation-related best practices within the financial services industry. Aon Hewitt also directly provides to the Committee market data, which the Committee references when determining compensation for the named executive officers.   — Corporate performance—The Committee members consider overall corporate performance by considering various measures, including the Corporation’s operating earnings as compared to corporate and business unit objectives. The Committee also takes account of the Corporation’s performance against the Corporation’s long-term strategic targets of earnings growth per share of 10-12%, revenue growth of 8-10%, return on common equity of 16-18%, and positive operating leverage. The Committee reviews all of these measures of performance in light of the prevailing economic environment. Aon Hewitt’s representative generally attends meetings of the Committee throughout the year during which compensation is reviewed and approved. Aon Hewitt’s representative provides general insights into compensation trends and prevailing market practices, presents its views on the compensation proposed by the Committee and participates in Committee meeting discussions. Aon Hewitt also undertakes specific projects when assigned by the Committee. In 2012, the Corporation paid Aon Hewitt and its affiliates $59,031 for executive compensation advisory services to the Committee. Aon Hewitt and its affiliates have also provided services unrelated to executive compensation to the Corporation and the trust for The Northern Trust Company Pension Plan (the Pension Plan) in 2012 and prior years. In 2012, the Corporation paid Aon Hewitt and its affiliates $2,211,709 in fees for other services, which included the administration of the Northern Trust Corporation Deferred Compensation Plan (the “DCP”), TIP, the Northern Trust Corporation Supplemental Thrift-Incentive Plan (the “Supplemental TIP”), the Northern Trust Corporation Supplemental Pension Plan (the “Supplemental Pension Plan”) and certain other retiree benefit plans, as well as valuation, budgeting and other general communication and consulting services relating to retirement plans. In 2012, the trust for the Pension Plan paid Aon Hewitt and its affiliates $1,158,665 in fees for other services, which included administration, actuarial and tax services related to the Pension Plan. Northern Trust management also paid $76,350 to McLagan, a consulting firm owned by Aon Hewitt to provide market data services. The fees paid to Aon Hewitt and its affiliates for other services by the Corporation and the Pension Plan trust were not approved in advance by the board of directors or the Committee; however, the board of directors and the Committee were aware of the other services being provided to the Corporation by Aon Hewitt and its affiliates. The Committee considered the independence of Aon Hewitt in light of new SEC rules and NASDAQ listing standards. The Committee evaluated Aon Hewitt’s independence, including consideration of the following factors: (1) other services provided to the Corporation by the consultant; (2) fees paid by the Corporation as a percentage of the consulting firm’s total revenue; (3) policies or procedures maintained by the consulting firm that are designed to prevent a conflict of interest; (4) any business or personal relationships between the individual consultants involved in the engagement and a member of the Committee; (5) any company stock owned by the individual consultants involved in the engagement; and (6) any business or personal relationships between the Corporation’s executive officers and the consulting firm or the individual consultants involved in the engagement. The Committee discussed these considerations and concluded that the work of the consultant did not raise any conflict of interest. Timing of Equity Compensation Award Procedures The Committee complies with the requirements of the Northern Trust Corporation 2012 Stock Plan, including the requirement that stock options may not be granted at less than 100% of the fair market value of Northern Trust’s common stock on the date of grant. For each grant approved by the Committee, the date of grant is the date on which the Committee acts to approve the award. Northern Trust does not time the grants of its equity compensation awards for the purpose of affecting the value of such executive compensation. Equity awards to named executive officers are generally made in February.   Deductibility of Executive Compensation The Corporation views the tax deductibility of executive compensation under Section 162(m) of the Code as an important factor in determining the forms and amounts of executive compensation. The Corporation, through the Committee, reviews each material element of compensation on a continuing basis and takes steps to assure deductibility if that can be accomplished without sacrificing flexibility and other important elements of the overall executive compensation program. Elements of Northern Trust’s Executive Compensation Program There are seven principal elements of the Northern Trust Executive Compensation Program, each of which is discussed below. In making determinations regarding these elements of compensation, the Committee’s overall goal is to establish total executive compensation that appropriately rewards performance, ensures alignment with stockholders’ interests and remains responsive to competitive factors in the marketplace for executive talent. Thus, while the Committee’s determinations with respect to each of these elements of compensation may reflect unique characteristics of that element (for instance, in the case of annual cash incentives, performance of the Corporation), the Committee’s overall decision making is governed by a collective evaluation of the elements of compensation, with a view toward establishing an appropriate level of total executive compensation. — Recommendations of the Chairman and CEO—The Chairman and CEO makes recommendations with respect to base salary, annual cash incentive and equity compensation for each named executive officer other than the Chairman and CEO. These recommendations are based on the Chairman and CEO’s assessment of the named executive officer’s performance as compared to business unit and individual performance goals established by the Chairman and CEO for each business unit and each named executive officer, other than the Chairman and CEO. In determining recommended compensation levels, the Chairman and CEO, with input from the Corporation’s Head of Corporate Risk Management, specifically evaluates each named executive officer’s performance with regard to business unit risks and individual adherence to risk and compliance policies and procedures. — Business Unit and Individual Performance—In the context of the Chairman and CEO’s recommendations, the Committee considers various measures of business unit performance in light of the objectives for that unit, such as revenue growth, new business generation as compared to lost business, client retention and satisfaction, and risk management. The Committee also reviews measures of individual performance for each named executive officer, such as adherence to and compliance with risk management and compliance policies and demonstrated leadership qualities. Key Elements of Named Executive Officer Total Compensation — Advice of the Committee’s consultant—The Committee periodically seeks advice from Aon Hewitt, its independent executive compensation consultant. Aon Hewitt is typically present at all meetings of the Committee and provides additional information regarding competitive pay practices, offers counsel on the appropriate application of the Committee Guidelines, or provides advice on specific, individual pay actions as requested. Compensation Element Link to Compensation Philosophy Type of Plan Key Features — Current and historical compensation—The Committee reviews the compensation history of each named executive officer including current and historical base salary, annual cash incentive history, historical equity compensation awards, and currently outstanding equity awards. The Committee does not evaluate or set each element of compensation independently of the other elements. Rather, the Committee adopts a holistic approach to establishing the total compensation package of each executive. Applying the Corporation’s core values and drawing upon the sources of information discussed above, the Committee utilizes the various elements of compensation as building blocks to construct a complete compensation package for each executive that appropriately reflects the three core design criteria of rewarding performance, ensuring alignment with stockholders, and remaining responsive to Base Salary Targeted at competitive factors in the marketplace for executive talent. Additionally, the Committee seeks to achieve a desired level of consistency in the character of paylevels among its executive officers. In reviewing measures of corporate financial performance in 2010, the Committee adjusted for the impact of an after-tax benefit totaling $20.9 million ($.09 per share) realized by the Corporation in connection with an indemnification liability related to Visa, Inc. (“Visa”). The fourth quarter of 2007 included an after-tax charge of $94.2 million ($.42 per share) reflecting the previously reported initial $150.0 million pre-tax charge for accruals related to indemnifications of Visa. In 2008, the Corporation realized an after-tax benefit of $153.5 million ($.68 per share) that is reflected in a pre-tax gain of $167.9 million on the partial redemption of the Corporation’s Visa shares in the initial public offering and a $76.1 million offset to previously established Visa indemnification accruals and related charges. The after-tax benefit realized in 2009 reflects a third quarter 2009 pre-tax benefit of $17.8 million from a further offset to previously established Visa indemnification accruals and related charges. Given the nature of the Visa-related adjustments, the Committee chose to focus upon operating earnings, a non-GAAP financial measure which excludes Visa related adjustments, exclusive of the Visa benefit as opposed to reported earnings in its review of the Corporation’s annual financial performance. In particular, the use of operating earnings impacts the Corporation’s earnings growth per share for 2010 (negative 14.8% excluding Visa versus negative 13.3% including Visa) and the Corporation’s return on average common equity for 2010 (9.9% excluding Visa versus 10.1% including Visa). The following table provides the Corporation’s reported earnings prepared in accordance with generally accepted accounting principles in addition to its results reflecting operating earnings, a non-GAAP financial measure, in orderpeer group companies to provide investors and others with a clearer indication of the results and trends in the Corporation’s core businesses, absent Visa adjustments: competitive salary Cash      Year Ended December 31, 2010 ($ In Millions Except Per Share Data)    Amount   Per Share Reported Earnings    $669.5   $2.74 Visa Indemnification Accrual (net of $12.1 tax effect)    (20.9)   (0.09) Operating Earnings    $648.6   $2.65 Principal Elements of the Corporation’s Executive Compensation Program The principal elements of the Corporation’s executive compensation program are designed to reflect the overall philosophy outlined above including a focus on total compensation with appropriate levels of variable pay compared to fixed salary and a strong emphasis on long-term, equity-based compensation for the Corporation’s most senior officers. The Corporation has historically enjoyed a stable, effective leadership team by identifying, retaining, and developing its key executive talent. The named executive officers in this proxy statement have been employed by the Corporation for an average of 25 years. Each of the principal elements of the Corporation’s executive compensation program, as discussed below, contributed to this success. Cash Compensation The Corporation typically pays two types of cash compensation to its named executive officers: base salaries and annual cash incentives. Base Salaries The Corporation believes that base salaries should provide a fixed level of annual income consistent with ana named executive officer’s position and responsibilities, competitive pay practices, and internal equity of pay among the named executive officers. Target base salary Base salaries, as described in this proxy, reflect 2012 compensation-related decisions and payments. Key Elements of Named Executive Officer Total Compensation Compensation Element Link to Compensation Philosophy Type of Plan Key Features Short-Term Annual Cash Incentive Aligns a named executive officer’s annual cash incentive award with stockholders’ interests by linking maximum award to a percentage of net income and actual award to executive’s performance. Provides total compensation opportunities that are targeted at competitive levels foramong the Corporation’s executive officers included in the Committee Guidelines described above broadly reflect median salary levels for similar positions at the Tier 1 peer group companies listed on page 31. However, the Committee does not take a formulaic approach to setting target base salary levels at a market median level. Instead, where appropriate, the Committee also considers internal pay equity for comparable key executive officer positions and establishes base salary targets that balance market pay practice with internal equity. In the case of each named executive officer, the Committee utilizes its discretion in setting the actual base salary and the annual adjustment of the salary relative to the target level set forth in the Committee Guidelines by evaluating each officer with respect to factors such as the following: (i) experience and qualifications of the individual executive, (ii) the executive’s tenure in the position or a position of similar level, (iii) significant changes in assignment or scope of responsibility, (iv) individual performance and contributions over the prior year relative to established goals and expectations for the position, and (v) internal pay equity.companies. Cash With respect to executives new to the Management Group, the Committee seeks to increase actual base salary gradually to the appropriate target pay level as the executive officer gains experience and tenure in the new position. The Committee also monitors the Committee Guidelines to ensure that the target base pay level remains appropriate. Annual base salary adjustments are generally effective April 1. Salary adjustments, if any, for promoted executives typically take effect upon the executives’ promotion date and assumption of new responsibilities. Base Salary Determinations.The base salaries of all named executive officers remained unchanged in 2010. Annual Cash Incentives The Committee determines and approves annual cash incentives for the Corporation’s executive officersare approved under the provisions of the stockholder-approved Management Performance Plan (the “MPP”).MPP. Awards under the MPP are intended to qualify as performance basedperformance-based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”) because, among other things, they are tied to the Corporation’s net income results for the prior year and may not exceed a fixed maximum. Cash awards, as described in this proxy, are linked to each named executive officer’s performance in 2012, although paid in 2013. Long-Term Compensation Aligns compensation with the following maximum funding opportunityinterests of stockholders by motivating them to act as fixed by the MPP: (i) the award for the Chairman, the CEO, or a combined Chairman and CEO position may not exceed 0.6% of consolidated net income (or approximately $4,017,000 for 2010); (ii) the award for the President, any Vice Chairman, the COO, or a combined President and COO position may not exceed 0.4% of consolidated net income (or approximately $2,678,000 for 2010); and (iii) the award for each of the other MPP participants may not exceed 0.3% of consolidated net income (or approximately $2,008,500 for 2010). In its design of the award limitations under the MPP, the Corporation sought to reflect the core values of itsowners. Also provides total compensation philosophy. By establishing the maximum funding opportunity as a percentage of the Corporation’s net income results for the prior year, the Corporation directly ties this element of compensation to a key measure of the Corporation’s performance. It also aligns the executive’s incentives with those of its stockholders. The upper limit of the executive’s potential award opportunity rises in direct proportion to the extent the Corporation (and the executive) produces positive operating results for the Corporation’s stockholders. In establishing these opportunities the Committee also took into account prevailing financial industry practices, as advised by its compensation consultant, in order to ensure that the award opportunities were competitive. But to emphasize the need to avoid excessive awards, the Corporation placed an upper cap on potential MPP awards. In the same vein, the MPP requires achievement of net income in order for any awards to be granted under the MPP. If positive net income is not achieved by the Corporation, the MPP prohibits the granting of incentive awards for that year. Within the general construct of the MPP award limitations, the Corporation also retains its discretion to consider a variety of financial and non-financial measures and individual performance factors as well as the guideline reference ranges set forth in the Committee Guidelines. The guideline reference ranges are not performance targets. Rather, they provide a reference range that generally reflects a balance betweentargeted at competitive pay practices relative tolevels among the peer group as well as consideration of internal pay equity among comparable executive officer positions.companies. Stock As is the case with base salaries, annual cash incentives actually awarded to the named executive officers are not tied to any specific formula. Instead, working within the limits established by the MPP and in consideration of the reference range in the Committee Guidelines, the Committee exercises its discretion in setting the particular award within this range based upon such factors as the Corporation’s performance for the prior year, and the particular executive’s tenure, historical compensation, and individual performance factors. For 2010, because net income was positive for the year, the MPP would have allowed the Chairman and CEO to receive anOptions Cash Long-term incentive cash award of up to $4,017,000 (0.6% of $669.5 million). However, based on the considerations discussed below and in consideration of target incentive level for the Chairman and CEO under the Committee Guidelines, the Committee exercised its discretion to set the actual award to the Chairman and CEO below the maximum funding opportunity prescribed by the MPP. Named executive officers may elect to have all or any portion of an annual cash incentive award deferred under the Northern Trust Corporation Deferred Compensation Plan (“DCP”) for a fixed term of years or until retirement. If the executive’s employment terminates before the scheduled distribution date due to death, disability, or the occurrence of some other distribution event consistent with the requirements of the Code, deferred amounts will be distributed pursuant to the terms of the DCP. Upon election, amounts deferred may be invested in various funds, generally consistent with those available to all employees who participate in TIP, which is a 401(k) plan. Annual Cash Incentive Determinations. Based on reported earnings of $669.5 million for fiscal 2010, the maximum funding opportunity for cash incentives under the MPP was $4,017,000 for the Chairman and CEO and $2,008,500 for each of the other named executive officers. In addition to the maximum individual cash incentive limit under the MPP, the Committee Guidelines set forth a cash incentive target for the Chairman and CEO of approximately 250% of base salary and approximately 150% of base salary for all other named executive officers. Discussion and Analysis. Within the context of the maximum MPP limits and the Committee Guidelines, actual cash incentive awards are determined by the Committee, in its sole discretion, after taking into consideration a variety of performance measures and other factors. These typically include the following: — The Corporation’s net earnings for the year in relation to the established profit plan for the year and in the context of the overall economic environment; — The overall performance of the Corporation in relation to its long-term strategic goals; — The financial and operating results of the applicable business unit including, as appropriate, revenue growth, growth in client assets, international growth, net income, risk management, and expense control; — The named executive officer’s success in achieving individual goals and objectives including, as appropriate, leadership, compliance and risk management, employee relations, client service, communication, ethics, diversity, and the development of senior officers; and — In the case of named executive officers other than himself, the recommendations of the Chairman and CEO. The Chairman and CEO provided recommendations to the Committee with respect to MPP awards for 2010 for named executives other than himself. In making these recommendations, the Chairman and CEO considered, among other factors, the following corporate financial measures: — Actual corporate earnings for 2010 in the context of planned earnings and the financial and macro economic environment during 2010; and — Corporate performance against its long-term strategic goals as noted below: Performance Measure Annual Target Actual 2010 Results Earnings Growth per Share 10% to 12% -14.8%* Revenue Growth 8% to 10% -3.7%* Return on Common Equity 16% to 18% 9.9%* Operating Leverage Positive Negative * Based on Operating Earnings The Corporation did not achieve these long-term, across cycle, strategic objectives in 2010. We recognize these targets as difficult to achieve in the current economic environment, but continue to believe they currently reflect our long-term, across cycle, strategic objectives. Performance in relation to these long-term goals is one of a variety of financial and non-financial factors the Committee considered in determining 2010 compensation and such goals are considered primarily as long-term strategic objectives rather than annual targets. Recommended 2010 MPP awards for named executive officers other than the Chairman and CEO ranged from $700,000 to $725,000, ranging from 85% to 88% of the target level award and from 35% to 36% of the maximum award of $2,008,500 under the MPP. Variances in individual bonus amounts primarily reflect individual results with regard to business unit financial or operating goals. The Committee concurred in these recommendations and approved payment of annual bonuses under the MPP in the amounts set forth in the column entitled “Non-Equity Incentive Plan Compensation” in the Summary Compensation Table found on page 52. In determining the 2010 MPP award for the Chairman and CEO, the Committee considered these overall corporate financial measures as well as performance of the Chairman and CEO against various other financial and non-financial goals including overall leadership, revenue growth, client retention, operational efficiency, succession planning, and overall strategic guidance during a difficult economic cycle. The Committee approved payment of an annual bonus of $2,000,000 under the MPP as set forth in the column entitled “Non-Equity Incentive Plan Compensation” in the Summary Compensation Table found on page 52. The approved MPP award compares to a target award of $2,500,000 under the Committee Guidelines and a maximum individual amount under the MPP of $4,017,000. The Corporation expects that the performance measures, as well as the additional factors noted above, will be the same measures evaluated in setting annual cash incentives awards for 2011, subject to any revisions in the Corporation’s long-term strategic goals. Equity Compensation The Corporation uses equity compensation to provide long-term incentives for its named executive officers. The use of equity compensation serves to align the interests of the named executive officers with those of the Corporation’s stockholders. Long-term, equity-based compensation is the most significant component of overall compensation. Long-term incentive compensation is comprised of PSUs, RSUs, stock options and long-term cash. The Corporation believes that an emphasisnumber of PSUs earned is based on long-term, equity based pay with meaningful time periods for vesting, along with stock ownership guidelines, contributes to continuity and stability within the Corporation’s executive leadership.return on equity, determined in accordance with GAAP, subject to adjustment for pre-established, objectively determinable factors.(1) ForForms2012, long-term incentives were made up of Equity Compensation Utilized.Equity compensation typically takes the form of non-qualifiedone-third PSUs, one-third stock options, restricted stock units, or performance stock units settled only in common stockand one-third long-term cash. For2013, long-term compensation incentives will be made up of the Corporation. The Corporation also grants a limited number of cash-settled restricted stock units in certain non-U.S. locations where legal, regulatory, and administrative issues make impractical the settlement of awards in shares. The Amended and Restated Northern Trust Corporation 2002 Stock Plan also provides for the issuance of other types of equity-based awards, including stock awards, stock appreciation rights, and performance shares. For a further description of significant features ofone-half PSUs, one-quarter stock options restricted stock units, and one-quarter RSUs. 2012 individual performance stock units, see the footnotes to the table entitled “Outstanding Equity Awards at Fiscal Year-End” beginning on page 57 of this proxy statement. Equity Compensation Determinations.For 2010, under the Committee Guidelines referred to above, the guideline dollar value of equity compensation was approximately seven times base salary for the Chairman and CEO and approximately three to four times base salary for the otheris considered when determining named executive officers. For purposesofficers’ long-term incentive awards to be delivered in 2013. Key Elements of the Committee GuidelinesNamed Executive Officer Total Compensation Compensation Element Link to Compensation Philosophy Type of Plan Key Features Retirement and for communicating compensation decisions, the dollar value of equity compensation is defined as 100% of the fair market value at grant for all restricted or performance stock unitsHealth and one-third of the fair market value at grant for all stock options. Equity value using these assumptions will be somewhat different than equity compensation reported under accounting rules as required elsewhere in the proxy statement. The Committee Guidelines provide the Committee with a reference for an appropriate and competitive equity award value. In addition, the Committee considers a variety of individual factors as well as internal equity to determine the actual dollar value of equity compensation for each named executive officer. Stock Options. Stock option grants made in 2010 to the named executive officers are shown in the Grants of Plan-Based Awards table presented elsewhere in this proxy statement. Stock options granted in 2010 vest in equal installments over a four-year vesting period. Restricted Stock Units. Restricted stock unit awards made in 2010 to the named executive officers are shown in the Grants of Plan-Based Awards table presented elsewhere in this proxy statement. Restricted stock units awarded in 2010 vest with respect to 50% of the award on each of the third and fourth anniversaries of grant, subject to the executive’s continued employment with the Corporation. Discussion and Analysis.The Corporation’s equity compensation component of total compensation supports all three of the key criteria established by the Committee in designing the executive compensation program. Stock options and other forms of equity compensation align the interests of executives with the Corporation’s stockholders by encouraging and motivating executive officers to act as owners with an equity stake in the Corporation. Additionally, consistent with the Corporation’s objective of providing total compensation that is competitive for comparable positionsWelfare Benefits Targeted at the Corporation’smedian level of a peer group of companies the Corporation reviews and considers the size, type, and mix of equity awards granted to named executive officers at its peer-group companies. The Corporation’s equity compensation element is performance based in two important respects. First, the level of the equity compensation award takes account, as described below, of an executive’s particular performance, the Corporation’s performance, and the contributions made by the executive to the Corporation’s performance. Second, the Corporation views stock options as inherently performance based inprovide benefits that the award will not provide any financial benefit to an executive unless the stock price increases following the grant of the award. Additionally, the Corporation occasionally makes other types of awards which attain value only to the extent that the associated performance goals are satisfied. The Committee Guidelines provide a reference pointcompetitive against which the Committee determines the annual equity award of each named executive officer. Committee Guidelines generally reflect a balance between competitive pay practices relative to the peer group as well as consideration of internal pay equity among comparable executive officer positions and the Corporation’s philosophy regarding the relative mix of cash and equity compensation desired. The Committee sets the actual amount of total equity compensation for each executive as an adjustment against this reference guideline based on its discretionary assessment of specific objective and subjective factors relating to the following: —companies.   the named executive officer’s experience and tenure in his or her position, prior and expected individual performance, and the executive’s potential long-term impact on the financial success of the Corporation; — the named executive officer’s strategic leadership, teamwork, and individual contributions as a member of the Corporation’s Management Group; — the desire to maintain internal equity in long-term incentive opportunity when compensating the senior leadership team; — the recommendations of the Chairman and CEO with respect to each named executive officer other than himself; — the advice of the Committee’s independent compensation consultant; and — the value of equity compensation awarded to the named executive officer in prior years. The Committee undertakes this exercise of discretion in the context of the Committee’s focus on total compensation and, accordingly, takes into consideration the base salary adjustment, the annual cash incentive, and the other equity awards granted to the named executive officer. There is no formula that assigns specific weight to these factors, and the relative importance of these factors may vary year to year. In most years, as in 2010, the Chairman and CEO’s recommendation is a very significant factor in the setting of equity compensation for named executive officers other than the Chairman and CEO. The following are the specific objective and subjective factors considered by the Committee in the setting of the total equity compensation of each named executive officer for 2010 at its February 15, 2010 meeting: — The Committee considered the recommendations of Aon Hewitt, its independent consultant, and the Committee Guidelines and awarded Mr. Waddell an annual equity award with a dollar value, as defined in the Committee Guidelines, of $7,000,000 to be delivered 50% in the form of non-qualified stock options and 50% in the form of restricted stock units. The Committee’s approval of this award reflects the Committee’s discretionary assessment of Mr. Waddell’s ability to positively impact the long-term financial success of the Corporation and its stockholders. Mr. Waddell’s equity award was at the higher limit of the Committee Guidelines but the Committee deemed it competitive and appropriate. — All other named executive officers received an equity award with a value, as defined in the Committee Guidelines, of $2,000,000 to be delivered 50% in the form of non-qualified stock options and 50% in the form of restricted stock units. The approved award values were within the established Committee Guideline range of three to four times base salary. The award for each individual reflects the Committee Guideline range, the Chairman and CEO’s recommendation, and the Committee’s discretionary assessment of confidence in the strategic direction and leadership demonstrated by each of the named executive officers. The Committee believes that a mix of stock options and either restricted stock units or performance stock is generally consistent with prevailing practices among its peer group and provides the most effective incentive to encourage stock price appreciation and ownership by its named executives. Retirement Benefits Description of Principal Retirement Benefits.The named executive officers participate in The Northern Trust Company Pension Plan (the “Pension Plan”) and TIP on the same terms as all other United States-based eligible employees. The named executive officers also participate in the Northern Trust Corporation Supplemental Pension Plan (“Supplemental Pension Plan”) and the Northern Trust Corporation Supplemental Thrift-Incentive Plan (“Supplemental TIP”), which provide eligible employees, including the named executive officers, with the portion of their retirement benefits that cannot be paid under the Pension Plan and TIP due to applicable Code and Pension Plan limits. Pension Plan and Supplemental Pension Plan.The Pension Plan and the Supplemental Pension Plan together provide named executive officers with an annual benefit paid at age 65 equal to the executive’s average compensation for his or her highest 60 consecutive calendar months prior to retirement, multiplied by 1.8% and then further multiplied by years of credited service up to a maximum of 35 years. This amount is then reduced by an amount based on the executive’s Social Security covered compensation and credited service. The portion of this benefit not in excess of various limits imposed by the Code and the Pension Plan is paid under the Pension Plan, and the portion of the executive’s benefit in excess of these amounts, if any, is paid under the Supplemental Pension Plan. This benefit is reduced if the executive retires and begins receiving benefit payments before age 62 (or age 60 under certain circumstances). All named executive officers have completed three years of vesting service and thus are fully vested in their pension benefits. TIP and Supplemental TIP. Under TIP, named executive officers can defer a portion of their base salary and receive employer matching contributions equal to 50% of the first 6% of deferred salary. If the Corporation meets an annual earnings goal, the Corporation will make a contingent matching contribution of 50% of the first 3% of deferred salary to TIP, for a maximum matching contribution of 4.5% of salary. No contingent matching contribution was made to TIP for 2010, since the Corporation did not reach its earnings goal for that year. Under Supplemental TIP, named executive officers can contribute a portion of their base salary that exceeds the annual Code compensation limit ($245,000 in 2010). The Corporation makes a matching contribution under Supplemental TIP using the formula in TIP, provided, however that Supplemental TIP matching contributions are limited to 50% of the first 6% of deferred salary. The named executive officers are fully vested in their retirement benefits under TIP and Supplemental TIP. 2010 Retirement Benefits.The aggregate change during 2010 in the actuarial present value of each named executive officer’s accumulated retirement benefit under the Pension Plan and Supplemental Pension Plan appears in the column “Change in Pension Value and Nonqualified Deferred Compensation Earnings” in the Summary Compensation Table presented elsewhere in this proxy statement. The actuarial present value of each named executive officer’s accumulated retirement benefit under the Pension Plan and Supplemental Pension Plan and the number of years of his or her credited service appear in the Pension Benefits table presented elsewhere in this proxy statement. The employer’s matching contributions made under TIP and Supplemental TIP on behalf of each named executive officer are included in the “All Other Compensation” column of the Summary Compensation Table presented elsewhere in this proxy statement. Pension 401(k) Discussion and Analysis.The purpose of the Corporation’s retirement program is to provide financial security in retirement in two ways: (i) an employer-provided basic benefit under the Pension Plan and Supplemental Pension Plan and (ii) employee contributions, together with matching contributions from the employer, under TIP and Supplemental TIP. Retirement benefitsHealth / Welfare Benefits are designed with respect to employees as a groupthe entire Northern Trust workforce in mind and thus are not specifically structured for the named executive officers. The design of the Corporation’s retirement program for employees, including the named executive officers, reflects the following considerations:   — Income replacement: The Corporation targets aggregate retirement benefits, including employer-provided contributions, and Social Security benefits, for an employee with 25 years of service equal to approximately 80% of current pension-eligible income. — Individual savings: The retirement program encourages employees to contribute to their individual retirement savings through participation in TIP and Supplemental TIP. — Competitiveness: The Corporation targets aggregate retirement benefits at approximately the median level of the following peer group companies: —     Bank of America Corporation —     The Bank of New York Mellon Corporation —     BB&T Corporation —     Capital One Financial Corporation —     Citigroup Inc. —     Fifth Third Bancorp —     JPMorgan Chase & Co. —     KeyCorp —     Marshall & Ilsley Corporation —     The PNC Financial Services Group, Inc. —     Regions Financial Corporation —     State Street Corporation —     SunTrust Banks, Inc. —     U.S. Bancorp —     Wells Fargo & Company The above peer group utilized in assessing the design and competitive posture of the overall employee benefit program of the Corporation, including retirement benefit practices affecting named executive officers, is a broad sample of companies in the financial industry that operate in the same geographic areas as the Corporation. This information is used to assess the Corporation’s competitive position relative to other broad-based, “all employee” benefit plans and practices affecting all employees, including executives, such as medical insurance, life insurance, qualified pension and profit sharing plans, and vacation policies and practices. The focus of this peer group is competitive labor market practices affecting the total employee population and broadly reflecting the Corporation’s general labor market. In contrast, the peer group referenced on page 31 is a more focused group of financial institutions with which we compete for executive and management talent. Comparative information from this peer group is used to assess the competitiveness of total compensation for individual executive officers including the named executive officers and to develop the Committee Guidelines. ForAdditional Elements of Compensation2013 Perquisites and Other Benefits 2010 Perquisites and Other Benefits. The Corporation provided the following perquisites to its executive officers in 2010: — Financial consulting and tax return preparation services; — Personal use of automobiles under the Corporation’s travel and entertainment policy, which requires reimbursement of personal use of automobiles, except in limited circumstances where there is a related business purpose; and — Relocation assistance, including payments for temporary living, travel to and from the old and new location, movement of household goods, and tax gross-up offsets for certain taxable relocation benefits. The Corporation also reimburses the named executive officers for the payment of personal income taxes in connection with the use of company automobiles for business-related purposes where such use is considered a taxable benefit, refer to the named executive officer. The named executive officers also participate in the employer’s medical, retiree medical, dental, disability, and life insurance programs on the same terms as other employees. Disclosure of the dollar value of each perquisite providedchanges to the named executive officers in 2008, 2009, and 2010 is set forth in the table set forth in footnote 6 to the Summary Compensation Table presented elsewhere in this proxy statement.Pension Plan as described on pages 70-74. Perquisites Discussion and Analysis.Perquisites are not a principal element of the Corporation’s executive compensation, and unlike the Corporation’s cash and equity compensation, perquisites are not analyzed and evaluated under the “performance based,” “stockholder-aligned,” and “competitive” criteria which are centralintended to the Corporation’s executive compensation philosophy. The Corporation’s perquisites arebe limited in number and modest in dollar value in comparisonvalue. Perquisites are minimal and not a significant component of compensation. Annually reviewed to its principal elementsensure types and costs of compensation. Theyperquisites remained aligned with Northern Trust compensation philosophy. Financial Consulting / Tax Return Preparation Personal Auto Use Reimbursement Relocation Assistance Perquisites are intended to assist named executive officers in the performance of their duties on behalf of the Corporation, to help them manage some forms ofNorthern Trust and provide limited compensation to realize their intended value, or otherwise to provide benefitsfor activities that have a combined personal and business purpose.

Cash Retirement and costs of perquisites provided by the Corporation to its executive officers to be sure that the perquisites are in line with this philosophy.Health and Welfare Benefits Change in Control BenefitsService credit The Corporation believes it is in the interests of the Corporation and its stockholders in the event of a change in control to provide employment security arrangements for certain key executive officers of the Corporation. As a part of its executive compensation program, therefore, the Corporation has entered into employment security agreements with each of its named executive officers and certain other executives.Excise tax reimbursement Disclosure of potential change in control benefits payable to each named executive offer, assuming a change in control of the Corporation and termination of employment on December 31, 2010, is set forth below under “Potential Payments Upon Termination of Employment or a Change in Control of the Corporation.” Description of Change in Control Benefits. Payments under the employment security agreements are subject to a “double-trigger”: first, a change in control must occurand second, within two years following the change in control, the executive must terminate employment for “good reason” (e.g., a material reduction in job duties or responsibility, materially reduced or adverse changes in employment compensation or benefit programs, requirements for travel or relocation) or the executive’s employment must be terminated involuntarily without “good cause” (e.g., criminal conviction involving dishonesty, fraud or breach of trust, willful and substantial non-performance). The employment security agreements also protect an executive if the executive’s employment terminates for “good reason” or without “good cause,” as described above, during the period pending a change in control, defined generally as the period after the acquisition of 15% or more of the Corporation’s common stock or entry into an agreement with respect to, or public announcement of the intention to take, an action constituting a change in control event and prior to the effective time of the change in control event. Change in control is generally defined in the employment security agreements to include the acquisition of 20% or more of the Corporation’s common stock, certain mergers, consolidations and asset transfers, or the election, without the consent of two-thirds of the incumbent board of directors, of the lesser of three directors or a majority of the directors then in office. Change in control benefits under the employment security agreements generally include a lump sum cash payment equivalent to three years’ base salary and bonus and a prorated bonus for the year of termination, continuation of medical, dental, life insurance, and other similar benefits for three years, and full vesting of stock options, restricted stock units, and performance stock units. Terminated executives also receive a post-termination exercise period equal to the lesser of five years or the original expiration date for all outstanding non-qualified stock options and incentive stock options granted on or after September 25, 2001, a three-year age and service credit for benefits under the Corporation’s Supplemental Pension Plan, and up to an additional three years of age and/or service credit to determine eligibility and subsidy for participation in the Corporation’s retiree medical program. The employment security agreements also provide that the Corporation will reimburse the executives for any excise tax imposed on payments under the agreements as well as taxes imposed on such reimbursement amounts. Discussion and Analysis. The purpose of these agreements isprovisions are intended to provide an executive with sufficient security so that the executive is not distracted from job duties, financially threatened by potential job loss or motivated to act contrary to the best interests of the Corporation and its stockholders prior to, during or after a change in control. Key Elements of Named Executive Officer Total Compensation Compensation Element Link to Compensation Philosophy Type of Plan Key Features Severance Benefits Critical to Northern Trust’s ability to attract and retain employees and remain competitive against the peer group companies. Cash Consolidated Omnibus Budget Reconciliation Act (“COBRA”) All Northern Trust employees, including named executive officers, are eligible for these severance benefits, which are designed to support the needs of the entire workforce. These benefits are available to the executive officers on the same terms and conditions as all Northern Trust employees. Severance benefits provide reasonable benefits to employees who are involuntarily terminated without cause due to a reduction in force, job elimination or similar reasons specified in the severance plan. (1) When the PSUs were granted in 2013, the Committee identified specific types of objectively determinable factors that could affect the performance measure (return on equity) if the factors occur during the performance period. In doing so, the Committee established that the effects of those factors will be excluded from the calculation of the performance measure if any of them, alone or in combination, would produce a change in net income in excess of $100 million. Factors that result in an adjustment to the calculation of the performance measure include: acquisitions, dispositions, mergers, and similar transactions, and securities issuances and expenses in connection therewith; changes in accounting principles, tax laws or other laws that affect reported results that become effective during the performance period; litigation or regulatory settlements; charges and expenses for restructuring activity, including reductions in force; discontinued operations; asset write-downs; and any other gain, loss, income or expense with respect to the performance period that is nonrecurring in nature. The Committee retains the power to exercise negative discretion, as it deems appropriate under the relevant circumstances, to reduce the actual payouts under the PSUs below the payouts otherwise resulting from the application of adjustments for any of these factors. Base Salary The Committee believes that base salaries should provide a fixed level of annual income consistent with a named executive officer’s position and responsibilities, competitive pay practices and internal equity among the named executive officers. Base salaries, as described in this proxy, reflect 2012 actions and payments. Base Salaries Aligned with Market Base salary levels for executive officers are consistent with competitive salary market data among peer group companies. In 2012, the majority of executives did not receive a base salary increase. The Committee uses discretion in determining base salaries. It does not take a formulaic approach to setting target base salary levels but considers the following factors: — Individual performance and contributions over the prior year relative to established goals and expectations for the position — Internal pay equity for comparable key executive officer positions — Base salary targets that balance market pay practice with internal equity — Experience and qualifications of the individual executive — The named executive officer’s tenure in the position or a position of similar level — Any significant changes in assignment or scope of responsibility For new executives, the Committee’s philosophy is to gradually increase actual base salary to the appropriate target pay level as the named executive officer gains experience and tenure in the new position. The base salaries of all named executive officers remained unchanged in 2012 with the exception of the CFO, whose salary was increased by $25,000 to reflect the competitive salary market for his position. Base salary adjustments generally are effective April 1. Salary adjustments for promoted executives typically take effect upon the executive’s promotion date and assumption of new responsibilities. Short-Term Annual Cash Incentive Our short-term annual cash incentives are designed to reward the named executive officer’s role in attaining annual Corporation goals, which are reflected in attainment of positive consolidated net income, then adjusted based on other relevant performance measures described below. The Committee determines and approves annual cash incentives for the Corporation’s named executive officers under the provisions of the stockholder-approved MPP. Awards under the MPP are intended to qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). Annual cash incentives, as described in this proxy, are linked to each named executive officer’s performance in 2012 as well as being tied to the Corporation’s net income. Awards may not exceed a fixed maximum. In 2012, the MPP was amended to clarify that performance expectations for each participant includes a risk management expectation, and Annual Cash Incentive Aligned with Stockholders’ Interests By establishing the maximum for the MPP as a percentage of Northern Trust’s net income, the Corporation directly aligns executive officers’ short-term annual cash incentive awards with performance that impacts our stockholders. If the Corporation does not achieve positive net income, the MPP prohibits the granting of incentive awards for that year. also to state expressly that the Committee’s authority to exercise negative discretion includes the discretion to reduce a participant’s award as appropriate to meet all applicable regulatory requirements. As determined by the MPP, the annual cash incentive maximums are as follows: — Annual cash incentives for the Chairman and CEO may not exceed 0.6% of consolidated net income — Annual cash incentives for the President, any Vice Chairman, the COO, or a combined President and COO position may not exceed 0.4% of consolidated net income — Annual cash incentives for all other named executive officers may not exceed 0.3% of consolidated net income — No annual incentives can be paid in the absence of positive net income Award limitations under the MPP reflect our executive compensation philosophy. By establishing the maximum funding opportunity as a percentage of net income for the prior year, Northern Trust directly aligns named executive officers’ incentives with the interests of its stockholders. If net income rises, the named executive officers’ potential award values rise as well. Furthermore, if the organization does not achieve positive net income, the MPP prohibits the granting of incentive awards for that year. In February 2013, the Committee reviewed the maximum funding opportunity for each named executive officer based on the limits defined by the MPP. For the Chairman and CEO, the maximum funding opportunity was determined to be $4,123,800. The Committee considered overall performance results, the maximum funding limit defined by the MPP and the cash incentive award data reported by peer firms, adjusted for size, financial results, and shareholder returns, and awarded the Chairman and CEO actual cash incentive award of $2,000,000. A similar rationale was applied by the Committee in determining the cash incentive awards for the other named executive officers. Awards are calculated in light of the Corporation’s net income, but the final determination of annual cash incentives is not tied to any specific formula. Instead, the Committee exercises negative discretion to set the final award. In doing so, the Committee considers multiple financial measures such as return on equity, growth in revenue, earnings per share growth, and pre-tax profit margin. To a lesser degree, the Committee also considers non-financial measures in determining annual awards based on factors such as: — Applicable business unit financial and operating results — Individual performance factors — Risk management — Recommendations of the Chairman and CEO for named executive officers other than the Chairman and CEO — With respect to the Chairman and CEO, the Committee also considered the financial and non-financial goals previously discussed on pages 33-34. Long-Term Compensation Long-term incentive compensation is the most significant component of overall compensation and is designed to reward the performance of the named executive officers over time, as reflected in the Corporation’s long-term stock performance. Long-term incentive compensation typically takes the form of non-qualified stock options, PSUs or RSUs. The Committee emphasizes long-term incentives to align compensation with the interests of the stockholders. The Committee believes that long-term incentive compensation encourages executives to act as owners with an equity stake in Northern Trust, discourages inappropriate risk-taking and contributes to continuity and stability within the Corporation’s executive leadership. At its February 2012 meeting, the Committee considered market data and the recommendations of Aon Hewitt in determining long-term compensation awards for performance in 2011. The Committee decided to deliver the awards to all named executive officers in the form of one-third PSUs, one-third stock options and one-third long-term cash. In 2013, the Corporation delivered long-term incentive awards to named executive officers for performance in 2012 in the form of 50% PSUs, 25% stock options, and 25% RSUs. The Committee considers a variety of individual factors to determine the actual dollar value of long-term compensation for each named executive officer. The dollar value of equity compensation is generally defined as 100% of the fair market value at the time of grant for all RSUs or PSUs and one-third of the fair market value of the shares underlying grants of stock options at the time of grant for all stock options. For grants in 2012 for 2011 performance, consistent with both the prior year’s guideline and with the peer group’s long-term compensation levels, adjusted for size, financial results, and shareholder returns, the guideline dollar value of long-term compensation was approximately seven times 2011 year end base salary for the Chairman and CEO, approximately five times 2011 year end base salary for the President and Chief Operating Officer and approximately three and one-half times 2011 year end base salary for the other named executive officers. Based upon the dollar value definition described above, the named executive officers received the following dollar amounts of long-term compensation in 2012 in respect of 2011: Mr. Waddell, $7,000,000 (103% of guideline); Mr. Morrison, $3,500,000 (100% of guideline); Mr. O’Grady, $2,100,000 (109% of guideline); and each of Mr. Fradkin and Ms. Schreuder, $2,100,000 (100% of guideline). Long-term incentive awards were made at this level in 2012 for 2011 performance due to the Committee’s determination that there should be differentiation between the CEO, COO and the other named executive officers. As to the named executive officers other than the CEO and COO, the Committee desired to maintain internal equity in the long-term incentive opportunity among these individuals. In addition, the Committee referenced experience and tenure, prior and expected individual performance, potential long-term impact on the financial success of Northern Trust, strategic leadership, teamwork and individual contributions as a member of Northern Trust’s Management Group, mix of total compensation relative to each element of compensation, recommendations of the Chairman and CEO with respect to other named executive officers, and advice of the Committee’s independent compensation consultant. When determining long-term incentive compensation, the Committee has discretion to consider the base salary adjustment, the annual cash incentive, prior long-term incentive awards granted to a named executive officer, and individual performance over the prior year. The Committee is allowed flexibility in determining the value of total long-term incentive compensation for each named executive officer based on a review of objectives and subjective factors. There is no formula that assigns specific weights to these factors and the importance of these factors may vary from year to year. In addition to consideration of the long-term incentive compensation reported by peer banks, the following are the specific objective and subjective factors considered by the Committee in setting total long-term incentive compensation for each named executive officer for 2012 at its February, 2013 meeting: — Experience and tenure — Prior and expected individual performance — Potential long-term impact on the financial success of Northern Trust — Strategic leadership, teamwork and individual contributions as a member of Northern Trust’s Management Group — Committee’s desire to maintain internal equity in long-term incentive opportunity — Mix of total compensation relative to each element of compensation — Recommendations of the Chairman and CEO with respect to other named executive officers — Advice of the Committee’s independent compensation consultant Stock option grants made in 2012 to the named executive officers are shown in the Grants of Plan-Based Awards table presented on page 64. Stock options granted in 2012 vest in equal annual installments over a four-year vesting period. RSU awards made in 2012 to the named executive officers are shown in the Grants of Plan-Based Awards table presented on page 64. RSUs awarded in 2012 vest on the third (50%) and the fourth (50%) anniversaries of grant, subject to the executive’s continued employment with Northern Trust. For 2013, the following changes are being made to long-term compensation. These changes apply to the grants made in February 2013 — PSUs will represent one-half of long-term incentive compensation, up from one-third in 2012. PSU are awarded with a specified performance-based vesting target that inherently incorporates performance and risk. Similar to last year, the performance measure for the PSUs will be return on equity (ROE). For 2013, ROE, which shall be determined in accordance with GAAP, is subject to adjustment for pre-established, objectively determinable factors summarized in footnote 1 on page 49. — Stock options will represent one-quarter of the total value of each named executive officer’s long-term incentive compensation, down from one-third in 2012. — RSUs will represent one-quarter of the total value of each named executive officer’s long-term incentive compensation and will include expanded risk-based forfeiture and clawback provisions. These changes to the composition of long-term incentive awards are to further reinforce performance and the link between compensation and increasing stockholder value. Retirement and Health and Welfare Benefits Retirement benefits are generally designed with the entire Northern Trust workforce in mind and are not specifically structured for the named executive officers. The design of the Corporation’s retirement program for employees, including the named executive officers, reflects the following considerations: — Competitiveness: Northern Trust targets total retirement benefits at approximately the median level of a retirement benefits peer group of companies — Individual savings: The retirement program encourages employees to contribute to their individual retirement savings through participation in TIP and the Supplemental TIP The named executive officers are eligible for: — Pension Plan — Supplemental Pension Plan — TIP — Supplemental TIP Prior to April 1, 2012, the Pension Plan and the Supplemental Pension Plan provided all of the named executive officers, except for Mr. O’Grady, with an annual benefit determined under the Pension Plan’s Traditional Formula. The annual benefit under the Traditional Formula is equal to the participant’s average compensation for his or her highest 60 consecutive calendar months prior to retirement (“average compensation”) multiplied by 1.8% and then further multiplied by years of credited service, up to a maximum of 35 years. This amount is reduced by an amount based on the participant’s Social Security covered compensation and credited service. Mr. O’Grady’s employment with the Corporation began on August 15, 2011. Therefore, under the terms of the Pension Plan, his benefits under the Pension Plan and Supplemental Pension Plan for his entire period of credited service are calculated under the Pension Plan’s “Pension Equity Plan (PEP) Formula,” rather than the Traditional Formula. Under the PEP Formula, each year a participant earns a specific pension credit “percentage,” determined in accordance with a schedule in the Pension Plan, which varies directly with his or her total number of years of credited service. A participant’s PEP Formula lump sum amount is equal to the sum of his or her pension credit percentages multiplied by “average compensation.” A participant’s annual benefit under the PEP Formula is equal to a single life annuity commencing at age 65 that is the actuarial equivalent of his or her PEP Formula lump sum amount. The portion of each named executive officer’s benefit, calculated under either the Traditional Formula or the PEP Formula as applicable, not in excess of various limits imposed by the Code and the Pension Plan, is paid under the Pension Plan. The portion of the executive’s benefit in excess of these amounts, if any, is paid under the Supplemental Pension Plan. A participant’s annual benefit under the Traditional Formula is reduced if the participant retires and begins receiving benefit payments before age 62, or age 60 under certain circumstances. A participant’s annual benefit under the PEP Formula is reduced if the participant retires and begins receiving payments before age 65. All named executive officers, except for Mr. O’Grady, have completed three years of vesting service, and thus are fully vested in their pension benefits. Like many companies, Northern Trust has taken steps to reduce both short and longer-term expense volatility of its Pension Plan while continuing to provide a compensation package that is competitive within its peer group. As part of these efforts, the Corporation made the following changes to the Pension Plan effective April 1, 2012. — All participants, including the named executive officers, accrue benefits under the PEP Formula for credited service after March 31, 2012. — Participants retained any accrued benefit earned under the Traditional Formula, which was based on their credited service and average compensation calculated as of March 31, 2012, provided that a participant’s average compensation as of March 31, 2012 will be indexed at a rate of 1.5% per year for any period on and after April 1, 2012, during which the participant earns credited service under the Plan. — The PEP Formula was amended effective April 1, 2012. As a result of these changes, the current named executive officers, other than Mr. O’Grady, are entitled to an annual benefit equal to the sum of their accruals: — Under the Traditional Formula for credited service before April 1, 2012, with average compensation adjusted as described above, and — Under the amended PEP Formula for any credited service, if any, after March 31, 2012. Mr. O’Grady will continue to accrue a benefit based solely on the PEP Formula for his credited service. He will be entitled to an annual benefit equal to the sum of his accruals: — Under the prior PEP Formula for credited service before April 1, 2012, and — Under the amended PEP Formula for any credited service after March 31, 2012. Under TIP, named executive officers can defer a portion of their base salary and receive employer matching contributions equal to 50% of the first 6% of deferred salary. For 2011, if the Corporation met an annual earnings goal, the Corporation made a contingent matching contribution of 50% of the first 3% of deferred salary to TIP, for a maximum matching contribution of 4.5% of salary. The contingent matching contribution was made to TIP for 2011, since the Corporation reached its earnings goal for that year. However, TIP was amended to provide that no contingent matching contribution would be made for 2012, even if the Corporation met its earnings goal for that year. TIP was further amended to discontinue contingent matching contributions for 2013 and subsequent years, but with the Committee retaining the discretion to authorize a discretionary employer contribution to TIP, which may be in the form of a profit sharing contribution, or other form of employer contribution, as determined by the Committee. Under Supplemental TIP, named executive officers can contribute a portion of their base salary that exceeds the annual Code compensation limit ($250,000 in 2012). The Corporation makes a matching contribution under Supplemental TIP using the formula in TIP, provided, however, that Supplemental TIP matching contributions are limited to 50% of the first 6% of deferred salary. All named executive officers, except Mr. O’Grady, are fully vested in their retirement benefits under TIP and Supplemental TIP. Specified values for each named executive officer’s retirement benefits appear on page 70. The named executive officers also participate in Northern Trust’s health and welfare benefits, including medical, retiree medical, dental, disability and life insurance programs, on the same terms as other employees. Perquisites Perquisites are intended to assist named executive officers in the performance of their duties on behalf of Northern Trust and provide compensation for activities that have a combined personal and business purpose. The Corporation’s perquisites are intended to be limited in number and modest in dollar value in comparison to the cash and equity elements of compensation. The Committee annually reviews Perquisites Aligned with the Philosophy of Northern Trust The Committee annually reviews the types and costs of perquisites to ensure they remain aligned with the compensation philosophy of Northern Trust. the types and costs of perquisites to ensure they remain aligned with the compensation philosophy of the Corporation. Northern Trust provided the following types of perquisites to its named executive officers in 2012: — Financial Consulting/Tax Return Preparation — Personal Auto Use Reimbursement The Corporation also reimburses named executive officers for the payment of personal income taxes in connection with the use of company automobiles for business-related purposes. The dollar value of each perquisite provided to the named executive officers in 2010, 2011 and 2012 can be found in the Summary Compensation Table on page 60. Employment Security Arrangements Northern Trust has entered into employment security arrangements for certain key executive officers of the Corporation, including each named executive officer. The purpose of these agreements is to provide an executive with sufficient security so that the executive is not distracted from job duties, financially threatened by potential job loss, or potentially motivated to act contrary to the best interests of Northern Trust and its stockholders prior to, during, or after a change in control. Change in Control and Severance Provisions Help Northern Compete with Peer Group Companies Northern Trust believes the employment security agreements and severance benefits are critical to compete with its abilitypeer group companies to attract and retain key executives fortalent, including at the following reasons:executive level. The Corporation further believes the employment security agreements are critical to its ability to attract and retain key executives for the following reasons: — The Corporation does not have employment agreements with its named executive officers; theofficers — The protection afforded by the employment security agreements provides appropriate motivation for the Corporation’s executives when considering whether any change in control is inincentives that align with the best interests of the Corporation;Corporation and its stockholders — Change in control provisions for executives are standard among peer group companies and are important to a competitive total compensation package — Change in control provisions under Northern Trust’s employment security agreements generally include: — A lump sum cash payment equivalent to three years’ base salary and bonus, and a prorated bonus for the year of termination — Continuation of medical, dental, life insurance and other similar benefits for three years — A three-year age and service credit for benefits under the Supplemental Pension Plan, and up to an additional three years of age and/or service credit to determine eligibility and subsidy for participation in Northern Trust’s retiree medical program — For new agreements in 2011 and subsequent years, no reimbursement for any excise tax imposed on payments under the agreements or for taxes imposed on such reimbursement amounts In order to receive benefits under the employment security agreements, two events must occur (except as noted above with respect to equity awards): — A change in control protection for executives is prevalent inmust occur — The executive must terminate employment “with good reason” or the competitive environment in whichexecutive’s employment must be terminated by the Corporation operates.“without good cause” within two years following the change in control — Severance Benefits The Corporation maintains“With good reason” termination includes a broad-based severance planmaterial reduction in job duties or responsibility, materially reduced or adverse changes in employment compensation or benefit programs, and requirements for substantially all full-time U.S. employees. The named executive officers participate in this plan on the same termstravel or relocation — “Without good cause” termination includes involuntarily termination, such as all other eligible employees. Descriptioncriminal conviction involving dishonesty, fraud or breach of Severance Benefits. The named executive officers, like all other eligible employees participating in the severance plan, receive severance benefits that include a lump sumtrust, and willful and substantial non-performance. A change in control is generally defined in the employment security agreements to include the acquisition of 20% or more of the Corporation’s common stock, certain mergers, consolidations and asset transfers, or the election—without the consent of two-thirds of the incumbent board of directors—of the lesser of three directors or a majority of the directors then in office. The employment security agreements also protect a named executive officer if the executive’s employment terminates during the period pending a change in control, defined generally as the period after the acquisition of 15% or more of the Corporation’s common stock or entry into an agreement with respect to, or public announcement of the intention to take, an action constituting a change in control event and prior to the effective time of the change in control event. Beginning in 2011, Northern Trust discontinued inclusion of excise tax gross-ups in new employment security agreements. In addition, the Terms and Conditions for 2012 equity awards made prior to October 2012 provide for full vesting of unvested stock options, RSUs and PSUs upon an actual change in control, with or without termination of employment, or upon termination during a pending change in control. As noted above, equity awards made in October 2012 and thereafter provide for “double-trigger” vesting in connection with a change in control (which requires that (i) both a change in control and a qualifying termination occur prior to acceleration of vesting or (ii) a change in control occur and the acquirer refuses or is unable to assume the existing awards). Disclosure of potential change in control benefits payable to each named executive officer, assuming a change in control of the Corporation and termination of employment on December 31, 2012, is set forth in the Potential Payments Upon Termination of Employment or a Change in Control of the Corporation section on page 80. Northern Trust has discontinued inclusion of tax gross-ups in new employment security agreements for executive officers. The form of employment security agreement that reflects this change was filed as an exhibit to the Corporation’s second quarter 2011 Quarterly Report on a Form 10-Q. This change is reflected in the employment security agreements for the three executive officers whose agreements were entered into after March 2011. Severance Benefits The purpose of the severance plan is to provide reasonable benefits to employees who are involuntarily terminated without cause due to a reduction in force, job elimination or similar reasons specified in the severance plan. Northern Trust believes that the availability of severance benefits allows the Corporation to compete with its peer group companies in attracting and retaining talent. The named executive officers participate in this plan on the same terms as all other eligible and similarly situated Northern Trust employees. Under such circumstances, named executive officers are eligible to receive severance benefits that include: — A lump sum payment of two weeks of base salary for each year of completed service up to, but less than 25 years, or 52 weeks of base salary for 25 years or more of completed service to the Corporation, provided, that benefitsCorporation. Benefits may not exceed two times the lesser of (i) the named executive officer’s annualized base salary for the year preceding the year in which the named executive officer’s termination, of employment occurs or (ii) the annual Internal Revenue Service Code compensation limit for retirement plans ($245,000 in 2010). Underfor the plan, eligible employees (including the named executive officers) also would be entitled to a Consolidated Omnibus Budget Reconciliation Act (“COBRA”)year of termination. — A COBRA subsidy based on their length of service to help cover the costs of continuation coverage under the employer’s medical and dental plans, full vesting under TIP and Supplemental TIP, one additional year of vesting service under the Pension Plan and the Supplemental Pension Plan, enhanced early retirement eligibility under the Pension Plan for employees who have reached age 54 with 14 years of credited service, and outplacement assistance. — These severance benefits are contingent upon execution of a release, waiver and settlement agreement with the Corporation. Severance payments will be reduced by any severance payments made under employment security agreements or any other benefit plan, program or individual contract. Discussion and Analysis. The purpose of the severance plan is to provide reasonable severance benefits to employees who are involuntarily terminated without cause due to a reduction in force, job elimination, or similar reasons specified in the severance plan. The Corporation believes that the availability of severance benefits allows the Corporation to compete with its peer group companies in attracting and retaining key executives. Other Issues Relevant to Executive Compensation Timing of Equity Compensation Awards The Committee generally meets in February of each year to consider and act with respect to stock option and stock unit awards (including performance stock units) for the Corporation’s executive officers for the then current fiscal year. This is the same meeting at which annual salary adjustment decisions are made, and cash incentive awards under the MPP are determined based on performance during the recently completed year. The Committee’s February meeting follows the Corporation’s public release of its earnings results for the recently completed fiscal year. The Committee, on occasion, may grant additional equity awards at other times during the year to newly hired or newly promoted executive officers or, in isolated cases, for special retention purposes. For each grant approved by the Committee, the date of grant is the date on which the Committee acts to approve the award. The Committee acts in strict compliance with the requirements of the Amended and Restated Northern Trust Corporation 2002 Stock Plan, including the requirement that stock options may not be granted at less than 100% of the fair market value of the Corporation’s common stock on the date of grant. The Corporation does not time the grants of its equity compensation awards for the purpose of affecting the value of such executive compensation, nor does it time grants to precede or follow disclosures of material nonpublic information. The Committee has authorized the Chairman and CEO and the Executive Vice President, Human Resources and Administration to grant non-qualified stock options and restricted stock units to certain employees (but not including any named executive officer or other executive officers subject to Section 16 of the Securities Exchange Act of 1934), subject to certain conditions and limitations. These grants are effective as of the date of the next regularly scheduled meeting of the Committee following such grant, with the exercise price of the stock options equal to 100% of the fair market value on the effective date. This delegated authority is designed for limited use in connection with new hires or newly promoted executive officers, or for special retention purposes. This delegated authority was exercised once during 2010 in order to address a critical turnover and retention situation affecting two employees. Stock Ownership Guidelines Long-term, equity-based compensation is a principal element of the Corporation’s executive pay program and, for its most senior executives, it is the largest component of direct compensation. In addition to emphasizing equity-based compensation, the Corporation has a long-standing practice of emphasizing stock ownership and retention by its senior executives. The Corporation maintains formal Stock Ownership Guidelines which stipulate expected levels of individual ownership and policies regarding long-term retention. The current guidelines establish a minimum expected level of ownership based on the executive’s position and defined as either a specific number of shares or a multiple of base salary (or, in the case of non-employee directors, a multiple of annual cash retainer). The guidelines apply to the Chairman and CEO, all other named executives, all other Executive Vice Presidents of the Corporation and all non-employee directors of the Corporation. Ownership guidelines for the Chairman and CEO and other named executive officers have been established at or above typical industry practices. Under the current guidelines, the Chairman and CEO is expected to maintain minimum share ownership levels equal to the lesser of the number of shares having a value equal to ten times base salary or 150,000 shares. For all other named executive officers, the minimum ownership guideline is the lesser of the number of shares having a value equal to five times base salary or 45,000 shares. The calculation of shares of common stock includes shares purchased on the open market, shares owned jointly with or separately by spouses and children, shares held through TIP, shares obtained through stock option exercises (but not including unexercised stock options) and stock award distributions, and 50% of unvested restricted stock units, stock awards and deferred stock units. For non-employee directors, the minimum ownership guideline is the lesser of the number of shares having a value equal to five times the annual cash retainer or 10,000 shares. In addition, non-employee directors are expected to meet a minimum share ownership level of 1,000 shares within one year from the date they are initially elected to the board, and the remainder is expected to be owned within five years of joining the board. The calculation of shares for non-employee directors is similar to that of executive officers except that non-employee director deferred units are counted at 100% toward both (a) the minimum stock ownership level set forth in the guidelines and (b) the minimum 1,000 shares required for new non-employee directors. The Chairman and CEO and each named executive officer currently meet or exceed established guidelines and all non-employee directors who have served at least five years currently meet or exceed the stock ownership guidelines. Roles of the Committee, Management and Consultants Role of the Committee. At its February meeting each year, the Committee reviews the total compensation of each named executive officer of the Corporation. The Committee has adopted the Committee Guidelines referenced above, which are used to set base salaries, determine annual cash incentives for the year just concluded, and approve equity incentive awards for the current year. The Committee and the Chairman and CEO use the guidelines to align the components of individual compensation with respect to the named executive officer’s individual responsibilities, contributions, and the overall success of the Corporation’s business. Total compensation is determined within the context of providing an appropriate mix of base salary, cash and equity incentives, and retirement benefits. During the course of the year, the Committee also reviews the Corporation’s retirement benefit program and other forms of benefits and compensation, including perquisites, that may be paid to the named executive officers. The Committee makes executive compensation decisions after careful review and analysis of information deemed relevant. In doing so, it considers all components of the Corporation’s executive compensation program in total rather than looking at any one component in isolation. In its review, the Committee recognizes and considers the impact that certain compensation actions may have on the potential values of other pay and benefit programs. In making compensation decisions, the Committee reviews summary sheets showing the dollar value of the following components of compensation and benefits for each named executive officer during their recent history with the Corporation, including: SUMMARY COMPENSATION TABLE The following table sets forth compensation information for the Corporation’s Chairman and CEO, current and former chief financial officer, and the three other most highly compensated executive officers for the year ended December 31, 2012.   — Base salaries; Name and Principal Position (a)   Year (b)     Salary ($)(1) (c)     Bonus ($) (d)     Stock Awards ($)(2) (e)     Option Awards ($)(3) (f)     Non-Equity Incentive Plan Compen- sation ($)(4) (g)     Change in Pension Value and Nonqualified Deferred Compensation Earnings ($)(5) (h)     All Other Compen- sation ($)(6) (i)     Total ($) (j)   Frederick H.

As provided in the Committee charter, the Committee has sole authority to select, retain, and terminate the engagement of any consultant in connection with any compensation and benefits matter, and has authority to obtain advice and assistance from internal or external legal, accounting, or other advisors. As discussed in more detail below under the caption“Role of Aon Hewitt,” the Committee has retained Aon Hewitt as its human resources consulting firm to advise the Committee on matters pertaining to executive compensation. (2)Stock Awards. This column shows the grant date fair value of the restricted stock unit and performance stock unit awards computed in accordance with FASB ASC Topic 718. See footnote 22 to the Consolidated Financial Statements contained in the Corporation’s 2012 annual report to stockholders for a discussion of the assumptions made by the Corporation in the valuation of these stock unit awards, including that dividend equivalents will be paid on these stock unit awards. Included in this table are performance stock unit awards, as follows: 53,456 units awarded to Mr. Waddell; 26,728 units awarded to Mr. Morrison; 16,037 units awarded to Mr. O’Grady; 16,037 units awarded to Mr. Fradkin; and 16,037 units awarded to Ms. Schreuder. Such units are eligible to vest based on the Corporation’s return on equity generally in accordance with the following schedule: Role of the Human Resources Department. The Corporation’s Human Resources Department assists the Committee in its compensation and benefits related determinations by collecting and providing to the Committee current Committee Guidelines, current as well as historical compensation paid to named executive officers, and any data that may be received from Aon Hewitt, the human resources consulting firm retained by the Committee in connection with matters pertaining to executive compensation. Such information is compiled and presented to the Committee in advance of the February meeting. The Head of Human Resources and Administration attends and participates in all Committee meetings. With respect to the compensation of the Chairman and CEO, the Human Resources Department provides current Committee Guidelines and current and historical compensation information for the Chairman and CEO. The Committee utilizes this data in undertaking its responsibility, consistent with its charter, to determine and approve the compensation (including each specific component comprising the total compensation package) to be paid or provided to the Chairman and CEO based on its evaluation of their respective performance against the Corporation’s goals and objectives. In determining any long-term incentive component of such compensation, the Committee’s evaluation takes into specific account the Corporation’s performance and relative stockholder return, the value of similar incentive awards given to the CEOs of peer group and other comparable companies, including companies in the financial services industry, the value of long-term incentive awards granted in recent years, and the retention of those awards. With respect to the compensation of all other executive officers other than the Chairman and CEO, the Human Resources Department assists the Chairman and CEO in his formulation of compensation recommendations by providing historical and current market data and specific information concerning the historical and current compensation of executive officers for which the Chairman and CEO is establishing recommendations. This includes information comparing such executive officers’ stock ownership measured against stock ownership guidelines approved by the Committee. Once the Chairman and CEO has established compensation recommendations for executive officers, those recommendations are presented by the Human Resources Department in a report to the Committee delivered in advance of the February meeting. This report includes the summary sheets referenced on page 47 of this proxy statement and provides the Committee with guidance comparing the recommendations against historical and current data and market trends, on a comprehensive basis, by individual position and by the specific compensation components listed on page 47 of this proxy statement. Role of the Chairman and CEO.The Committee, consistent with its charter, retains ultimate oversight and responsibility for review and approval of the compensation of executive officers. In fulfilling these obligations, the Committee benefits from the review and evaluation of executive officer compensation undertaken by the Chairman and CEO with assistance from the Corporation’s Human Resources Department. The Chairman and CEO provides to the Committee his recommendations for total compensation (including the specific elements and mix of such compensation) to be paid to each of the Corporation’s executive officers other than the Chairman and CEO. In establishing such recommendations, the Chairman and CEO evaluates the performance of executive officers during the prior year against performance expectations established by the Chairman and CEO. These performance expectations are not weighted or scored and are comprised of a mix of objective and subjective factors. As noted previously, some performance expectations may relate to quantitative aspects of the Corporation’s financial results, while others may be more qualitative aspects, such as the achievement of acquisition integration, risk management, client development, or diversity goals. In formulating his recommendations, the Chairman and CEO is assisted by the Human Resources Department which supplies current Committee Guidelines and current as well as historical compensation data for each executive officer. The recommendations of the Chairman and CEO are reviewed by the Committee in advance of its meeting. The recommendations are presented to the Committee by the Corporation’s Human Resources Department in a summary report that provides recommended and historical compensation levels for each named executive. The recommendations and this comparative data are reviewed and evaluated by the Committee in the context of any additional information on broader industry compensation trends and market practices as may be provided by Aon Hewitt. The Committee gives substantial weight to the recommendations of the Chairman and CEO, but retains the ultimate oversight and responsibility to make modifications to the total compensation or the levels of particular compensation elements recommended by the Chairman and CEO. Role of Aon Hewitt. The Committee has retained Aon Hewitt as its human resources consulting firm to advise the Committee on matters pertaining to executive compensation. Aon Hewitt’s engagement encompasses the following consulting services: — Assist the Committee’s decision-making with respect to executive compensation, ensuring that the Committee’s actions are consistent with the Corporation’s business needs, including risk management, pay philosophy, prevailing market practices, and relevant legal and regulatory mandates. — Provide market data as background against which the Committee can consider Chairman and CEO and senior management base salary, bonus, and long-term incentive awards each year. — Consult with the Committee on how best to make compensation decisions with respect to the Corporation’s management while continuing to represent stockholders’ long-term interests. — Apprise the Committee of best practices in association with director compensation. Aon Hewitt’s representative generally attends all meetings of the Committee throughout the year and undertakes such specific projects as assigned by the Committee from time to time. In 2010, Aon Hewitt’s representative attended all meetings of the Committee at which compensation was reviewed and approved, provided Aon Hewitt’s general insights into compensation trends and prevailing market practices, presented its views on the compensation proposed for approval by the Committee (taking into account its market research and insights into prevailing trends), and participated in Committee meeting discussions. In 2010, the Corporation paid Aon Hewitt and its affiliates $48,496 of fees in connection with executive compensation advisory services provided to the Committee. Aon Hewitt and its affiliates have also provided services unrelated to executive compensation to the Corporation and the trust for the Pension Plan in 2010 and prior years. In 2010, the Corporation paid Aon Hewitt and its affiliates $1,991,201 in fees for other services, which included the administration of the DCP, TIP and Supplemental TIP and certain other retiree benefit plans, as well as valuation, budgeting and other general communication and consulting services relating to retirement plans. In 2010, the trust for the Pension Plan paid Aon Hewitt and its affiliates $1,008,840 of fees for other services, which included administration, actuarial and tax services related to the Pension Plan. The fees paid to Aon Hewitt and its affiliates for other services by the Corporation and the Pension Plan trust were not approved in advance by the board of directors or the Committee; however, the board of directors and the Committee were aware of the other services being provided by Aon Hewitt and its affiliates. Deductibility of Executive Compensation The Corporation views the tax deductibility of executive compensation under Section 162(m) of the Code as an important factor to be considered in determining the forms and amounts of executive compensation. The Corporation, through the Committee, reviews each material element of compensation on a continuing basis and takes steps to assure deductibility if that can be accomplished without sacrificing flexibility and other important elements of the overall executive compensation program. Base salary and the amounts set forth in the “All Other Compensation” column of the Summary Compensation Table do not, by their nature, qualify as “performance based compensation” under Section 162(m). The Corporation has taken appropriate steps, including obtaining stockholder approval, to qualify the MPP and the Amended and Restated 2002 Stock Plan as “performance based compensation” so that cash awards under the MPP and awards of stock options and performance stock units under the Amended and Restated 2002 Stock Plan are or will be fully tax deductible. Prior to 2010, the Corporation also provided in its restricted stock unit agreements under the Amended and Restated 2002 Stock Plan that the payment of the stock units is mandatorily deferred until the earlier of (a) the year in which the Committee reasonably anticipates that, if the payment is made during that year, the deduction of the payment will not be barred by Code Section 162(m), or (b) the period beginning with the date of the participant’s separation from service (as defined in the Amended and Restated 2002 Stock Plan) and ending on the later of the last day of the Corporation’s taxable year in which the participant incurs a separation from service or the 15th day of the third month following such separation from service. The mandatory deferral provision was originally expected to apply to the Corporation’s CEO; it has not been included in the restricted stock units granted by the Corporation in 2010 and later due to the fact that the mandatory deferrals were applying to additional executive officers and were causing the incentive compensation of those officers to be paid in a manner that the Committee determined to be inequitable, depending on whether or not the executive was subject to the Section 162(m) deduction limitation. The Corporation’s deductions under Section 162(m) are further restricted with respect to payments attributable to the period that the U.S. Treasury held equity or debt securities of the Corporation under TARP. The impact of these additional restrictions on deductibility is expected to be limited. Relationship of Compensation Practices to Risk Management In determining the compensation of the Corporation’s named executive officers, the Committee is cognizant of the fact that incentive compensation practices can, in certain circumstances, provide incentives for executives (and other employees) to take inappropriate risks. The Committee is mindful that it does not wish to create inappropriate incentives through its compensation arrangements. During the Corporation’s participation in TARP, the Committee and the Corporation’s senior risk officers reviewed the incentive and bonus compensation arrangements with the Corporation’s senior executive officers to ensure that those compensation arrangements did not encourage those executives to take such unnecessary and excessive risks. More recently, the Corporation conducted an assessment of its incentive compensation arrangements in connection with the Federal Reserve’s horizontal review of incentive compensation arrangements at large, complex banking organizations. In each case, the reviews resulted in a conclusion that the Corporation’s compensation arrangements did not inappropriately encourage risk taking by employees. Among the reasons for these conclusions were: — the fact that the Corporation is not in many of the lines of business that have often exposed firms to substantial risks (such as origination or securitization of sub-prime mortgage loans or significant proprietary derivatives trading or strategic investing); — the fact that the Corporation actively monitors employees to ensure that they work within established risk frameworks and limits; — the payment of a substantial portion of the compensation of the Corporation’s senior management in the form of long-term, equity-based pay that vests over a multi-year period and has an inherent risk adjustment factor based on the Corporation’s share value; and — the Committee’s stock ownership guidelines for senior management that are designed to align their stock ownership to the long term profitability of the Corporation. The Committee intends to continue to monitor the Corporation’s incentive compensation arrangements for executives and others with a view towards ensuring that the arrangements do not encourage inappropriate levels of risk taking among participants.

Stock options are granted with an exercise price equal to the closing sale price of the common stock on the date of grant and expire 10 years after the date of the grant. This approach is designed to motivate the executive to contribute to the creation of stockholder value over the long term. The Corporation currently grants only non-qualified stock options because it believes that the tax benefits to the Corporation of non-qualified stock options outweigh the potential tax benefits to the executives of incentive stock options. All stock options held by the named executive officers that were granted prior to 2005 vested on or before February 2008. All stock options granted in 2005 vested 100% on March 31, 2005. All stock options granted in 2006 and thereafter willare scheduled to vest in equal annual installments over a four-year vesting period determined by the Committee. IfPlease see “Equity Compensation Plans and Agreements—Stock Options” on pages 85-86 of this proxy statement for additional information about the executive dies or becomes disabled, thevesting and exercise of stock options (whether vested or unvested) become vested and may be exercised until the earlier of five years following death or disability or the expiration date of the option. If the executive retires, the stock options continue to vest in accordance with their terms and, once vested, may be exercised until the earlier of five years following retirement or the expiration date of the option. If the executive’s employment is terminated under certain circumstances entitling the executive to severance benefits, the executive’s stock options (whether vested or unvested) may be exercised until the earlier of 180 days following termination of employment or the expiration date of the option. If the executive is a member of the Management Group on the date of grant, is age 55 or older with a minimum of 10 years of employment on the date of termination of employment, and is not otherwise retirement-eligible pursuant to the Corporation’s retirement policy, the stock options continue to vest and, once vested, may be exercised until the earlier of five years following termination of employment or the expiration date of the option. In other instances, vested stock options expire on the earlier of three months following termination of employment or the expiration date of the option, and unvested stock options expire on termination of employment. Upon a change in control of the Corporation, all stock options become vested and exercisable.options. (2)Number of Restricted Stock Units. This column shows the number of unvested restricted stock units held by the named executive officers as of December 31, 2010.2012. Restricted stock units granted prior to 2006 vest over a five-year period, and restricted stock units granted in 2006 and thereafter vest 50% on the third anniversary of the date of grant and 50% on the fourth anniversary of the date of grant. Restricted stock unit awards entitle an executive to receive one share of common stock in the year in which the award vests. Restricted stock units vest over a specified vesting period determined by the Committee. Terms and conditions associated withDividend equivalents on the restricted stock units otherwise mirrorare paid on a current basis prior to vesting and distribution. Please see “Equity Compensation Plans and Agreements—Restricted Stock Units” on page 84 of this proxy statement for additional information about the performance stock units in termsvesting and distribution of the payment of dividend equivalents and pro-rata vesting upon death, disability, retirement, or termination of employment as described in footnote 4 below, except that the pro-rata vested restricted stock units will be distributed to the executive or the executive’s beneficiaries immediately upon the occurrence of the triggering event. In the event of a change in control, all restricted stock units become fully vested, but are not distributable until the occurrence of a regular distribution event, including expiration of the original specified vesting period or termination of employment.units. (3)Market Value of Restricted Stock Units.This column shows the market value of the unvested restricted stock units held by the named executive officers, based on a price of $55.41$50.16 per share (the closing market price of the Corporation’s common stock on December 31, 2010,2012, as reported by NASDAQ). (4)Number of Performance Stock UnitsUnits.. This column shows the number of unvested performance stock units held by the named executive officers as of December 31, 2010.2012. Performance stock units entitle an executive to receive shares of common stock, on a one-for-one basis, in the year in which the award vests, subject to satisfaction of pre-determined performance goals. Dividend equivalents on the performance stock units are paid on a current basis prior to vesting and distribution. IfPlease see “Equity Compensation Plans and Agreements—Performance Stock Units” on pages 84-85 of this proxy statement for additional information about the executive dies, becomes disabled, or retires during the performance period, or the executive’s employment is terminated during the performance period under certain circumstances entitling the executive to severance benefits, the executive or the executive’s beneficiaries will be entitled to receive avesting and distribution of a prorated number of performance stock units at the completion of the performanceunits. period upon certification that the applicable performance goals have been met. If the executive is a Management Group member on the date of grant, is age 55 or older on the date of termination of employment, and does not violate certain restrictive covenants concerning confidentiality and non-solicitation during the performance period, a prorated number of performance stock units is eligible for distribution at the completion of the performance period upon certification that the applicable performance goals have been met. In other instances where the executive leaves the Corporation during the performance period, the performance stock units are forfeited. Upon a change in control of the Corporation, all performance stock units become fully vested and are immediately distributable. (5)Market Value of Performance Stock Units.This column shows the market value of the unvested performance stock units held by the named executive officers, based on a price of $55.41$50.16 per share (the closing market price of the Corporation’s common stock on December 31, 2010,2012, as reported by NASDAQ). (6) Cancellation of Performance Stock Units. In January 2011, performance stock units granted in 2008 and included in this table were cancelled as a result of failure to meet minimum performance goals for the three-year period ending December 31, 2010. No unvested performance units remained following cancellation of the 2008 awards.

Pension Plan and Supplemental Pension Plan Defined benefit pension benefits are provided to employees under the Pension Plan and the Supplemental Pension Plan, and are available to all employees of the Bank and affiliates and subsidiaries that have adopted the Plans. The Pension Plan is a tax-qualified retirement plan that provides a retirement benefit as described below, which is subject to various limitations of the Code and the Pension Plan. The Supplemental Pension Plan is a non-qualified retirement plan that provides the portion of an employee’s benefit that cannot be paid under the Pension Plan due to the Code and Pension Plan limits. The material terms and conditions of the Pension Plan and the Supplemental Pension Plan as they relate to the named executive officers include the following: Eligibility:Eligibility: Employees participate in the Pension Plan after completing six months of vesting service. Employees with six months of vesting service who would have a portion of their benefit from the Pension Plan limited due to the Code or Pension Plan restrictions also participate in the Supplemental Pension Plan. All named executive officers participate in both Plans. Mr. O’Grady began participating in these Plans on February 15, 2012. Benefit Formula:Formula—Traditional Formula The: Prior to April 1, 2012, the benefits of the named executive officers, areexcept for Mr. O’Grady, were determined under the Pension Plan’s Traditional Formula. The Traditional Formula’s main components are service, eligible pay, age, and an offset for Social Security. The Traditional Formula first multiplies 1.8% by the average of the participant’s highest 60 consecutive calendar months of eligible pay. This amount is further multiplied by the participant’s years of credited service (up to a maximum of 35 years). The Social Security offset is then determined by multiplying 0.5% by (i) the lesser of the participant’s Social Security Covered Compensation limit or the average of the participant’s eligible pay for the three consecutive years prior to retirement by (ii) the participant’s years of credited service (up to 35 years). This offset is subtracted from the benefit amount previously calculated to determine the annual benefit amount produced by the Traditional Formula. The following definitions are used under the Traditional Formula:     —   Eligible Pay:“Eligible pay” is defined as base salary (including any before-tax payroll deductions), shift differential,differentials, overtime, and certain types of performance-based incentive compensation, including cash, Northern Performance Incentives under the Northern Partners Incentive Plan (“NPIP”), compensation under the MPP, payments from the then-existing Annual Performance Plan, and the cash value of stock options which were specifically paid in lieu of cash incentives from January 1, 2002 through April 30, 2004. Cash incentives deferred under the DCP are not included in eligible pay under the Pension Plan but are included in eligible pay under the Supplemental Pension Plan.     —   Social Security Covered Compensation:“Social Security Covered Compensation” means, for a participant, the average of the Social Security taxable wage base for each of the 35 calendar years ending in the year in which the participant attains Social Security retirement age. In determining Covered Compensation as of a certain year, the taxable wage base for any subsequent year is assumed to be the same as for the determination year. Benefit Formula—PEP Formula: Since Mr. O’Grady commenced employment on August 15, 2011, his benefits under the Pension Plan and Supplemental Pension Plan for his entire period of credited service are calculated under the Pension Plan’s “Pension Equity Plan (PEP) Formula”, rather than the Traditional Formula. Under the PEP Formula, each year a participant earns a specific pension credit “percentage,” determined in accordance with a schedule in the Pension Plan, that varies directly with his or her total number of years of credited service. A participant’s PEP Formula lump sum amount is equal to the sum of his or her pension credit percentages multiplied by the average of the participant’s highest 60 consecutive calendar months of eligible pay. (Prior to April 1, 2012, eligible pay was defined the same for the PEP Formula as for the Traditional Formula, except that eligible pay under the PEP Formula also included cash Sales and Technical Incentives under the NPIP up to 50% of the participant’s prior year’s base pay. Effective April 1, 2012, eligible pay under the amended PEP Formula includes all cash incentives under the NPIP.) A participant’s annual benefit under the PEP Formula is equal to a single life annuity commencing at age 65 that is the actuarial equivalent of his or her PEP Formula lump sum amount. The single life annuity is calculated using interest rate and mortality assumptions specified in the Pension Plan. Below is the schedule that was in effect until April 1, 2012, for determining the applicable pension credit percentage in the PEP Formula for a given year: For each full year of credited service that: The pension credit amount for such year of credited service shall be: Exceeds 0 but does not exceed 5 4.0% Exceeds 5 but does not exceed 10 5.0% Exceeds 10 but does not exceed 15 6.0% Exceeds 15 but does not exceed 20 7.0% Exceeds 20 but does not exceed 25 8.0% Exceeds 25 but does not exceed 30 9.0% Exceeds 30 but does not exceed 35 10.0% Exceeds 35 years 0.0% Benefit Formula—Changes: Effective April 1, 2012, the Pension Plan was amended to provide that for credited service earned after March 31, 2012, all employees, including the named executive officers will accrue benefits pursuant to the PEP Formula, which formula was also modified effective April 1, 2012. Therefore, the current named executive officers, other than Mr. O’Grady, will be entitled to an annual benefit equal to the sum of their accruals (i) under the Traditional Formula for periods of credited service before April 1, 2012, and (ii) under the amended PEP Formula for their periods of credited service, if any, after March 31, 2012. Each such executive’s pre-April 1, 2012 Traditional Formula benefits will be based on credited service and average compensation calculated as of March 31, 2012, provided that the executive’s average compensation as of March 31, 2012, will be indexed at a rate of 1.5% per year for any period on and after April 1, 2012 during which the executive earns credited service under the Pension Plan. In 2012, the Chairman and CEO’s pension value increased by $3,839,003. The changes made to the Pension Plan are anticipated to moderate future pension value increases. For 2012, the primary factors influencing the Chairman and CEO’s pension value increase include an increase of his final average pay calculation, the application of the average pay across his 35 years of credited service under the plan, and a decrease in the discount rate from 4.75% to 4.25% that resulted in an increase to the present value of his pension. Mr. O’Grady will continue to accrue a benefit pursuant to the PEP Formula with respect to all of his credited service. He will be entitled to an annual benefit equal to the sum of his accruals (i) under the prior PEP Formula for periods of credited service before April 1, 2012, and (ii) under the amended PEP Formula for periods of credited service, if any, after March 31, 2012. Below is the schedule that is currently in effect for determining the applicable pension credit percentage in the PEP Formula for a given year: For each full year of credited service that: The pension credit amount for such year of credited service shall be: Exceeds 0 but does not exceed 5 4.0% Exceeds 5 but does not exceed 10 4.0% Exceeds 10 but does not exceed 15 5.0% Exceeds 15 but does not exceed 20 6.0% Exceeds 20 but does not exceed 25 7.0% Exceeds 25 but does not exceed 30 8.0% Exceeds 30 but does not exceed 35 9.0% Exceeds 35 years 0.0% In applying the foregoing schedule, a participant’s credited service prior to April 1, 2012 is taken into account solely for purposes of determining the pension credit percentage applicable to credited service after that date. Benefit Formula—Supplemental Pension Plan: Pension benefits are first calculated under the combined Traditional Formula and PEP Formulas or solely under the PEP Formula, as applicable, without regard to the Code limits and including in eligible pay the amounts deferred under the DCP. They are then recalculated applying the Code limits and excluding DCP deferrals from eligible pay to determine the amount of the benefit that is payable from the Pension Plan. The difference between the total benefit calculation and the Pension Plan calculation is paid from the Supplemental Pension Plan. Benefit Entitlement:Entitlement: A participant is eligible to receive a benefit under the Pension Plan and Supplemental Pension Plan after completing three years of vesting service. Retirement:Retirement: A participant is eligible for a normal retirement benefit based on the combined Traditional and PEP Formulas or based solely on the PEP Formula, as described above, if his or her employment terminates on or after age 65 (or for participants who begin participation in the Pension Plan after age 60, upon the first to occur of reaching the fifth anniversary of commencement of participation or achieving five years of vesting service). A participant is eligible for an early retirement benefit if his or her employment terminates on or after age 55 and he or she has completed 15 years of credited service. TheA participant who terminates employment with three years of vesting service but prior to becoming eligible for a normal or early retirement benefit is eligible for a “vested terminee” benefit commencing any time after termination. Messrs. Waddell and Morrison are each eligible for early retirement benefits. All other named executives, other than Mr. O’Grady, have earned vested terminee benefits. Under the Traditional Formula, the early retirement benefit is equal to the normal retirement benefit described above, reduced by 0.5% for each month payments are received prior to age 62 (or prior to age 60 under certain circumstances). A participant who terminates employment with three years of vesting service but prior to becoming eligible for a normal or early retirement benefit is eligible for a “vested terminee” benefit commencing any time after termination, with payments reduced by 0.5% for each month up to 120 months that payments are received prior to age 65, then actuarially reduced for each month that payments are received prior to age 55. Additionally, Messrs. Waddell Under the PEP Formula, both the early retirement benefit and Morrison and Ms. Barrat“vested terminee” benefit are each eligibleequal to the normal retirement benefit (in the form of a monthly single life annuity as described above), adjusted for early retirement benefits. All other named executives have earned vested terminee benefits.commencement prior to age 65 (or for participants who begin participation in the Pension Plan after age 60, upon the first to occur of reaching the fifth anniversary of commencement of participation or achieving five years of vesting service). The adjustment is made using interest rate and mortality assumptions specified in the Pension Plan. Form of Benefit Payment: The Traditional Formula calculates the amount of benefit payable in the “normal” form. The normal form of benefit payment under the Pension Plan is a single life annuity in the case of an unmarried participant and a 50% joint and survivor annuity in the case of a married participant, although optional forms of payment are available, depending on marital status and age and years of service. A lump sum option is available in all cases. All optional forms are the actuarial equivalent of the normal form of payment. The normal form of benefit under the Supplemental Pension Plan is a five-year certain annuity, payable to the participant in five annual installments; if the participant dies prior to receiving full benefits, payments will continue for the remainder of the five years to a designated beneficiary. The installment payments are credited with interest equal to the greater of the annual yield on the monthly five-year Treasury securities with a constant maturity plus 150 basis points or the month-end Moody’s Long Term Aa Corporate Bond Index yield, determined as of the last month of the same calendar quarter as the interest rate used to calculate any lump sum benefit for the participant under the Pension Plan. If, however, the value of the Supplemental Pension benefit is $125,000 or less, the benefit is paid in a single lump sum. Assumptions.Assumptions. The assumptions used in calculating the present value of the accumulated benefit are set forth in footnote 21 to the Consolidated Financial Statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each contained in the Corporation’s 2010 Annual Report2012 annual report to Stockholders.stockholders.

Deferred Compensation Plan The Corporation maintains the DCP pursuant to which eligible employees, including the named executive officers, may defer all or a portion of their eligible annual incentive cash awards until a later date. The material terms and conditions of the DCP as they relate to the named executive officers include the following: Eligibility: An employee is eligible to participate in the DCP for any calendar year if as of the preceding November 15 he or she (i) was actively employed by the Corporation or a subsidiary and either resided in the U.S. or was a U.S. expatriate on temporary international assignment, (ii) participated in the Northern Partners Incentive Plan (with respect to performance, sales or technical incentives) or the MPP, and (iii) had an annual base salary of $100,000 or more or a combination of base salary and cash awards paid from April 1 of the prior year through March 31 of the current year equal to $150,000 or more. Contributions: Each participant must make an election prior to the beginning of a calendar year, and can elect to defer up to 100% of each eligible cash incentive award that will be paid for the second calendar year following the year of the election, subject to a minimum deferral of $2,500 of each cash incentive award. All deferrals are credited to an account maintained for the participant under the DCP. No employer contributions are made under the DCP. Vesting: A participant is fully vested in his or her entire DCP account balance at all times. Investments: Each participant’s DCP account is credited with earnings or losses based on investment alternatives made available under the DCP and selected by the participant. On a monthly basis, participants can change their DCP investment alternatives among the alternatives offered in the DCP. The 20102012 performance (net of fees) of the investment alternatives is as follows: Investment Alternative    Annual Return   Brandywine Multi-Cap Equity*Aberdeen Emerging Markets Institutional Fund      -1.0526.15 %  Dodge & Cox Stock*MFS Institutional International Equity Fund      0.97 %  MS Institutional Small Company Growth* 0.636.14 %  NIF Bond Portfolio      6.836.92 %  NIF Diversified Assets Portfolio      4.880.01 %  NIF Equity Index Portfolio      14.89 %  NIF Focused Growth Portfolio* -1.5915.92 %  NIF International Equity Portfolio      8.7811.65 %  NF Bond Index**Index      6.214.05 %  NF Mid Cap Index**Index      30.3617.76 %  NF Small Cap Index**Index      31.3916.20 %  NF Stock Index Fund (1.67 )%  Northern Multi-Manager Mid Cap      24.3214.42 %  PIMCO All Asset Fund 15.44 %  Prudential Jennison Small Cap Core Strategy***Strategy      19.57 %  RS Partners Small Company Value* 5.6113.47 %  Vanguard Inflation-Protected Securities Index**Index      4.586.78 %  Vanguard International Stock Index**Index      17.0518.14 %  Vanguard Retirement Income      9.398.23 %  Vanguard Target Retirement 2005      9.712.33 %  Vanguard Target Retirement 2010      11.4310.12 %  Vanguard Target Retirement 2015      12.4711.37 %  Vanguard Target Retirement 2020      13.1212.35 %  Vanguard Target Retirement 2025      13.8413.29 %  Vanguard Target Retirement 2030      14.4314.24 %  Vanguard Target Retirement 2035      15.1415.16 %  Vanguard Target Retirement 2040      15.1715.56 %  Vanguard Target Retirement 2045      15.1915.58 %  Vanguard Target Retirement 2050      15.2015.58 %  Vanguard Target Retirement 2055 15.58 %  Vanguard Target Retirement 2060 8.99 %  Victory Institutional Diversified Stock***Stock      15.3616.74 %  * Wells Fargo Advantage Core Bond Fund Investment alternative was available only through August 2, 2010.

Return shown above is return from August 2, 2010 through December 31, 2010.0.42 %  Distributions: At the time a participant makes a deferral election, he or she must elect a short-term deferral or a retirement deferral. If the participant elects a short-term deferral, distribution of such amount must be deferred until a later specified date, which is at least three years following the end of the year in which the cash incentive award would have otherwise been paid. The short-term deferral, including the attributable earnings or losses, is paid to the participant in a lump sum. If the participant elects a retirement deferral, distribution of such amount will be deferred until the participant retires after reaching eligibility for early or normal retirement under the Pension Plan. At the time the participant makes the retirement deferral election, he or she must also elect whether the deferral, including the attributable earnings or losses, will be paid in a lump sum or in installments payable over five or 10 years. Notwithstanding the foregoing, if the participant’s employment terminates before the scheduled distribution date, the short-term or retirement deferral, and attributable earnings or losses, will be paid in a lump sum within 60 days following the date of such termination. If the participant is deemed to be a “key employee” as defined by the Code, any distribution that was deferred after December 31, 2004 and is payable due to retirement or termination of employment will be delayed for six months following the date of such retirement or termination. Supplemental TIP Supplemental TIP is a non-qualified retirement plan that provides the portion of an employee’s benefit that cannot be paid under TIP due to the Code’s limit on the amount of a participant’s compensation that can be taken into account in determining TIP benefits. Account information provided for Supplemental TIP also includes account balances in the Northern Trust Corporation Supplemental Employee Stock Ownership Plan (“Supplemental ESOP”), which was frozen effective January 1, 2005 when the qualified Northern Trust Employee Stock Ownership Plan was merged into TIP. Contributions to Supplemental ESOP have not been permitted since January 1, 2005. The material terms and conditions of Supplemental TIP as they relate to the named executive officers include the following: Eligibility: An employee is eligible to participate in Supplemental TIP for any calendar year if he or she participates in TIP and as of the prior November 30th his or her base salary exceeded the Code compensation limit ($245,000250,000 in 2010)2012). Employees are eligible to participate in TIP and elect salary deferrals immediately upon their hire, and are eligible for employer matching contributions after six months of service. All named executive officers, other than Mr. O’Grady, participate in both Plans. Mr. O’Grady does not currently participate in Supplemental TIP. Contributions: Each participant must make an election prior to the beginning of a calendar year to contribute to Supplemental TIP a portion of his or her base salary that exceeds the Code compensation limit.compensationlimit. A participant’s election remains in effect for subsequent calendar years until revised or revoked by the participant. Any revision or revocation must be made prior to the calendar year in which the revision or revocation is to become effective. The Corporation makes a matching contribution under Supplemental TIP using the formula in TIP, (for 2010 a matching contribution equal towhich is 50% of the first 6% of deferred salary, for a maximum matching contribution of 3% of salary).salary. In addition, iffor 2011, since the Corporation meets anmet its annual earnings goal, the Corporation will makemade a contingent matching contribution of 50% of the first 3% of deferred salary to TIP. However, no contingent matching contributions willare ever made to Supplemental TIP. Further, TIP was amended to provide that no contingent matching contribution would be made to Supplemental TIP.TIP for 2012, even if the Corporation met its earning goal for that year. TIP has been further amended to discontinue the contingent matching contribution for 2013 and subsequent years, but with the Committee retaining the discretion to authorize a discretionary employer contribution to TIP, which may be in the form of a profit sharing contribution, or other form of employer contribution, as determined by the Committee. Vesting: Each participant generally vests in the employer contributions under TIP and Supplemental TIP on a graduated basis of 20% per year over five years and is fully vested after five years. The named executive officers, except Mr. O’Grady, are fully vested in their TIP and Supplemental TIP accounts. Mr. O’Grady is not yet vested in his TIP account and does not currently participate in Supplemental TIP. Investments: Each participant’s Supplemental TIP account is credited with earnings or losses based on investment alternatives made available under Supplemental TIP and selected by the participant (which are generally the same investment alternatives available to participants under TIP). On a monthly basis, participants can change their Supplemental TIP investment alternatives among the alternatives offered in Supplemental TIP. For 2010,2012, the investment alternatives available to Supplemental TIP participants were the same as those for DCP participants. The 20102012 performance of those investment alternatives is set forth on page 67 above.77. Distributions: No withdrawal or borrowing of Supplemental TIP assets is permitted during a participant’s employment. Distribution of the entire Supplemental TIP account balance generally is made to a participant within 90 days after the participant’s termination of employment. If the participant is deemed to be a “key employee”, as defined by the Code, the portion of his or her Supplemental TIP account accruing after December 31, 2004 is distributed as a single lump sum following the six month anniversary of the termination of employment. Deferred Stock Units As noted above in footnote 3 under the Option Exercises and Stock Vested table, restricted stock units granted prior to 2010 may be required to be deferred until the earlier of (a) the year in which the Committee reasonably anticipates that, if the payment is made during that year, the deduction of the payment will not be barred by the Code Section 162(m), or (b) the period beginning the with the date of the participant’s separation from service (as defined in the Amended and Restated 2002 Stock Plan) and ending on the later of the last day of the Corporation’s taxable year in which the participant incurs a separation from service or the 15th15th day of the third month following such separation from service. “Executive ContributionsContribution in Last FY” in the table above represent the value of the stock units required to be deferred, and “Aggregate Earnings in Last FY” represent the change in the value of the deferred stock units, which is based on the change in the value of the underlying shares of common stock into which the stock units convert. POTENTIAL PAYMENTS UPON TERMINATION OF EMPLOYMENT OR A CHANGE IN CONTROL OF THE CORPORATION The Corporation provides certain benefits to eligible employees upon certain types of termination of employment, including a termination of employment involving a change in control of the Corporation. These benefits are in addition to the benefits to which the employees would be entitled upon a termination of employment generally (i.e., (i) vested retirement benefits accrued as of the date of termination, (ii) stock-based awards that are vested as of the date of termination, (iii) the right to continue medical coverage pursuant to COBRA, and (iv) severance payments to salaried employees upon an involuntary termination of employment due to a reduction in force or job elimination). These incremental benefits as they pertain to the named executive officers are described below. The Corporation’s decision to enter into employment security agreements described below and the determination of the level of benefits under those agreements, as well as under various termination of employment scenarios were exercises in judgment, informed by (i) the recognition that the Corporation does not have employment agreements with its named executive officers, (ii) the Corporation’s desire to provide the named executive officers with sufficient security to assure they are not distracted and remain focused on maximizing stockholder value during and after a change in control, (iii) the Corporation’s goal of providing executive compensation at levels that are competitive with similar positions to those in its peer group companies, (iv) the nature and scope of the job responsibilities undertaken by the named executive officers, and (v) the terms of other types of compensation paid by the Corporation to the named executive officers. In particular, in setting the terms of the benefits payable to the named executive officers under various termination scenarios, the Committee was guided in large part by a desire to be sufficiently responsive to market forces and the environment in which the Corporation seeks to attract, retain, and motivate its named executive officers by providing benefits consistent and competitive with those of the peer group companies with which it competes for top executive talent. In initially establishing the form and level of post-termination benefits, the Committee received and reviewed relevant peer group company information provided by Aon Hewitt. In particular, this competitive peer group data influenced the decision of the Committee to provide for employment security agreements, to set the level of lump sum payments equal to three years of salary and bonus, and to provide for the vesting of equity compensation awards, the continuation of coverage under certain health and welfare plans, and other protections afforded in the event of a termination of employment in connection with a change in control or under other termination of employment scenarios. Employment Security Agreements The Corporation has employment security agreements with the named executive officers and certain other executive officers. The employment security agreements provide benefits upon the occurrence of the following terminations of employment that are in connection with an actual or pending change in control of the Corporation (as defined below):     —   A termination of the executive’s employment by the Corporation or a subsidiary without “good cause” that occurs either within two years after a change ofin control of the Corporation or during the period pending a change in control of the Corporation; or   —   An executive’s voluntary termination of employment with the Corporation or a subsidiary for “good reason” that occurs either within two years after a change in control of the Corporation or during the period pending a change in control of the Corporation. The benefits provided to a named executive officer upon such a termination of employment would consist of the items identified in the following seven bullet points:     —   A lump sum payment equal to three times the sum of (i) the named executive officer’s annual salary in effect on the date of employment termination, or if higher, the date of the change in control and (ii) the average of the named executive officer’s awards under the Corporation’s cash incentive plans for the last three fiscal years of participation in such plans prior to the date of termination, or, if higher, the date of the change in control. The amount of this payment to each named executive officer, assuming the named executive officer became eligible for benefits under the agreement due to a termination of employment on December 31, 20102012 (the last business day of 2010)2012), would be as follows: Mr. Waddell: $6,200,000;$8,525,000; Mr. Morrison: $3,050,000; Ms. Barrat: $3,050,000;$4,250,000; Mr. O’Grady: $3,450,000; Mr. Fradkin: $3,075,000;$3,900,000; and Ms. Schreuder: $3,100,000.$3,900,000.     —   A lump sum payment of a prorated portion of the average amounts paid to the named executive officer under the Corporation’s cash incentive plans for the last three fiscal years of participation in such plans prior to the date of termination, or, if higher, the date of the change in control, less any amounts paid to the named executive officer under those plans with respect to completed performance periods occurring in the year the named executive officer’s employment terminates. The amount of this payment to each named executive officer, assuming the executive became eligible for benefits under the employment security agreement due to a termination of employment on December 31, 2010,30, 2012, would be as follows: Mr. Waddell: $1,666,667;$1,866,667; Mr. Morrison: $466,667; Ms. Barrat: $466,667;$716,667; Mr. O’Grady: $575,000; Mr. Fradkin: $475,000;$700,000; and Ms. Schreuder: $483,333.$700,000.     —   With respect to equity awards: (i) full vesting of all stock options, (ii) all outstanding nonqualified stock options, and incentive stock options granted on or after September 25, 2001, remain exercisable for five years following termination of employment (or until the end of the option term, if earlier), (iii) full vesting of all outstanding restricted stock units, and (iv) full vesting and immediate distribution of all outstanding performance stock units at the maximum level (125%)as provided in the awards. The named executive officers become entitled to full and accelerated vesting upon an actual change in control, even if there is no termination of employment, or upon termination during a pending change in control. Assuming a termination of employment under the employment security agreement on December 31, 2010,2012 (the last business day of 2012), the fully vested equity awards would have the following values for each named executive officer:   Mr. Waddell:    $ 910,180       (stock options)    $ 1,043,989       (stock options)    $ 4,523,214       (restricted stock units)    $ 2,917,198       (performance stock units)    $ 3,121,461       (restricted stock units) Mr. Morrison:    $ 260,055       (stock options)    $ 521,998       (stock options)    $ 1,364,368       (restricted stock units)    $ 1,273,629       (restricted stock units)    $ 972,446       (performance stock units) Ms. Barrat:    $ 260,055       (stock options)    $ 1,364,368       (restricted stock units) Mr. O’Grady:    $ 1,138,531       (stock option)    $ 972,446       (performance stock units)    $ 2,316,857       (restricted stock units) Mr. Fradkin:    $ 260,055       (stock options)    $ 313,196       (stock options)    $ 1,920,344       (restricted stock units)    $ 3,252,191       (restricted stock units)    $ 972,446       (performance stock units) Ms. Schreuder:    $ 260,055       (stock options)    $ 313,196       (stock options)    $ 1,920,344       (restricted stock units)    $ 3,252,191       (restricted stock units)    $ 972,446       (performance stock units) The value of the fully vested stock options is based on the difference between the option exercise price and $55.41,$50.16, which was the closing market price of the Corporation’s common stock on December 31, 2010.2012 (the last business day of 2012). The value of the fully vested restricted stock units and performance stock units is also based on the $55.41$50.16 closing market price. The amounts set forth above with respect to performance stock units assume that these units vested pursuant to a change in control on December 31, 2010. In fact, these performance stock units were forfeited in 2011 due to the applicable performance goals not having been attained. In addition, the deemed vesting of these units accounts for $7,797,205 of the gross-up payments estimated below.     —   Continued coverage under the Corporation’s health, dental, life, accident, disability, and other welfare benefit plans for three years (or if earlier, until the executive becomes covered under similar plans maintained by another entity that provides at least equal benefits). If the named executive officer cannot be covered under any plan of the Corporation due to legal or contractual restrictions, the Corporation would provide the executive with substantially similar benefits and coverage. The value of this continued benefit coverage for three years to each named executive officer would be as follows: Mr. Waddell: $35,404;$32,327; Mr. Morrison: $35,404; Ms. Barrat: $30,488;$38,191; Mr. O’Grady: $31,497; Mr. Fradkin: $35,404;$38,191; and Ms. Schreuder: $35,404.$38,191. These amounts are derived by multiplying the Corporation’s annual cost of providing such coverage in 20102012 by three, to reflect a three-year benefit continuation period.     —   Up to an additional three years of age and/or service credits for purposes of determining eligibility and subsidy for participation in the Corporation’s retiree medical plans and an additional three-year age and service credit for benefits under the Supplemental Pension Plan. Assuming a termination of employment under the employment security agreement on December 31, 2010, the value of these age and service credits to each named executive officer would be: Mr. Waddell: $0; Mr. Morrison: $1,319,618; Ms. Barrat: $612,701; Mr. Fradkin: $262,147; and Ms. Schreuder: $1,133,582. The assumptions used in calculating the present value of the age and service credits are set forth in footnote 21 to the Consolidated Financial Statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each contained in the Corporation’s 2010 Annual Report to Stockholders. Assuming a termination of employment under the employment security agreement on December 31, 2012, the value of these age and service credits to each named executive officer would be: Mr. Waddell: $0; Mr. Morrison: $209,250; Mr. O’Grady: $151,390; Mr. Fradkin: $294,317; and Ms. Schreuder: $1,461,009. The assumptions used in calculating the present value of the age and service credits are set forth in footnote 21 to the Consolidated Financial Statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each contained in the Corporation’s 2012 annual report to stockholders.   —   Full vesting in benefits accrued under the Supplemental Pension Plan and Supplemental TIP. All named executive officers, other than Mr. O’Grady, are already vested in these benefits.     —   A gross-up payment to the executive to cover any excise and related income tax liability arising under Section 280G of the Internal Revenue Code as a result of any payment or benefit arising under the employment security agreement. Assuming a termination of employment under the employment security agreement on December 31, 2010,2012, the named executive officers would be entitled to the following gross-up payments: Mr. Waddell: $4,785,919;$5,108,565; Mr. Morrison: $0; Ms. Barrat: $2,005,672;Mr. O’Grady: $0; Mr. Fradkin: $1,934,604;$2,377,376; and Ms. Schreuder: $2,343,468.$2,924,178. For purposes of the employment security agreements:     —   “Good cause” means (i) the executive’s conviction of a criminal violation involving dishonesty, fraud or breach of trust with respect to the business of the Corporation or any subsidiary; (ii) the executive’s willful engagement in misconduct in the performance of his duties that causes material injury to the Corporation; (iii) the executive’s act that, if known to clients, customers, stockholders or regulators, would materially and adversely impact the business of the Corporation or any subsidiary; (iv) the executive’s act or omission that causes a regulatory body to demand, request, or recommend the suspension or removal of the executive from his position with the Corporation or any subsidiary; or (v) the executive’s willful and substantial nonperformance of his duties that is not cured within 10 days after written notice from the Corporation.     —   “Good reason” exists if (i) there is a material reduction in the executive’s authority, duties or responsibilities; (ii) there is a material reduction in the executive’s base salary; (iii) the Corporation materially changes the principal location in which the executive is required to perform services to outside the current geographical employment area, or the executive is required to spend more than 50 working days per year outside the current geographical employment area; or (iv) the Corporation fails to provide a level of employee benefits not materially less than those provided in the aggregate by such plans prior to the date of the agreement, or the date of the change ofin control, if greater.     —   “Change in control” means (i) a person’s acquisition of 20% or more of the voting power of the Corporation’s outstanding securities; (ii) the election, without the consent of two-thirds of the incumbent board of directors, of the lesser of three directors or a majority of the directors then in office; (iii) a merger or consolidation of the Corporation (subject to certain exceptions); or (iv) a sale of all or substantially all of the Corporation’s assets (subject to certain exceptions) or stockholder approval of a complete liquidation or dissolution of the Corporation.   —   “Period pending change in control” means (i) the period commencing upon the Corporation’s entering into an agreement, or the Corporation or any person’s public announcement of intention to take action, the consummation of which would result in a change in control, and ending upon the occurrence of the change in control or the abandonment or termination of such agreement or actions; (ii) the period commencing upon a person’s acquisition of 15% or more of either the then outstanding shares of the Corporation’s common stock or the voting power of the Corporation’s outstanding securities and ending upon the earlier of the occurrence of the change in control or one year following the person’s acquisition of the outstanding shares or voting power; or (iii) the period commencing upon the board’s adoption of a resolution that a pending change in control has occurred and ending upon the earlier of the change in control or one year following the board’s resolution. Equity Compensation Plans and Agreements As described below, a change in control of the Corporation or a named executive officer’s termination of employment with the Corporation or a subsidiary due to death, disability, or retirement (and which is not a termination as described in his or her employment security agreement) can result in enhanced benefits under the Corporation’s equity compensation plans and agreements. Restricted Stock Units/Performance Stock Units. If the executive dies, becomes disabled, or retires during the vesting/performancevesting period, or the executive’s employment is terminated during the vesting/performance period under certain circumstances entitling the executive to benefits under the Corporation’s severance plan, the executive or the executive’s beneficiaries will be entitled to receive a distribution of a prorated number of restricted stock units and, at the completion of the performance period upon certification that the applicable performance goals have been met, performance stock units. In addition, if an executive is a Management Group member on the date of grant, is age 55 or older on the date of termination of employment, and does not compete with the Corporation during the vesting/performance period, a prorated number of restricted stock units and, aton each remaining vesting date in the completion of the performancevesting period upon certification that the applicable performance goals have been met, performance stock unitsbecome vested and are eligible for distribution. In addition, in the case of restricted stock units granted after December 31, 2012, accelerated pro rata vesting and distribution provisions apply in the case of Management Group employees who satisfy certain conditions and who terminate employment for a government position, or terminate employment and thereafter accept a government position, and must dispose of any interest in the Corporation to satisfy ethics or conflict of interest laws or agreements. In other instances where the executive leaves the Corporation during the vesting/performancevesting period, the restricted stock units and performance stock units are forfeited. Upon a change in control of the Corporation, all restricted stock units granted to named executive officers prior to December 31, 2012, become fully vested immediately, and allare distributable upon the date they would otherwise have been distributed in the absence of a change in control; restricted stock units granted after December 31, 2012, are converted into units of the acquirer and continue to vest in accordance with the regular vesting schedule; provided, however, that they become fully vested in connection with a change in control if the executive experiences a qualifying termination of employment following the change in control (in which case they are distributed within 60 days). A qualifying termination is an involuntary termination of employment without “cause” or termination for “good reason,” as those terms are defined in the award agreements, that occurs after the change in control and prior to the second anniversary thereof. Notwithstanding the foregoing, in the event that both a change in control occurs and the acquirer refuses or is unable to agree to the foregoing conversion and vesting provisions, the award will be vested and will be distributed in accordance with the provisions of Code Section 409A, to the extent applicable. The agreements have been drafted to provide that in such event distribution may be in cash. Performance Stock Units.PSUs were granted in 2012 and 2013 to members of the Management Group. Each PSU constitutes the right to receive a share of the Corporation’s common stock and vests over a three-year performance period, subject to satisfaction of specified performance targets (“performance conditions”) that are a function of return on equity and continued employment until the end of the vesting period. If the executive dies, becomes disabled, or retires during the vesting/performance period, or the executive’s employment terminates during the vesting/performance period under certain circumstances entitling the executive to benefits under the Corporation’s severance plan, the executive or the executive’s beneficiary will be eligible for pro rata vesting and distribution at the end of the performance period, subject to certain conditions, including satisfaction of the performance conditions. In addition if the executive is a Management Group employee on the date of grant and terminates employment on or after attainment of age 55, the executive will be eligible for pro rata vesting and distribution at the end of the performance period, subject to certain conditions, including satisfaction of the performance conditions. In addition, accelerated pro rata vesting and distribution provisions apply in the case of Management Group employees who satisfy certain conditions (including the performance condition applied to modified period) and who terminate employment for a government position, or terminate employment and thereafter accept a government position, and must dispose of any interest in the Corporation to satisfy ethics or conflict of interest laws or agreements. Upon a change in control, performance stock units granted prior to December 31, 2012, become fully100 percent vested and are to be immediately distributabledistributed; with respect to performance stock units granted after December 31, 2012, a pro rata portion of each performance stock unit award (based on the portion of the performance period that has elapsed as of the change in control) are eligible to vest based on the Corporation’s actual performance at the time of the change in control and are to be paid out at the end of the performance period, subject to accelerated distribution upon an assumptiona qualifying termination. The remainder of maximumthe performance and payoutaward converts at the target level (125%) as providedof performance specified in the awards.performance stock unit agreement into an award with respect to the acquirer of an equal economic value and vests subject only to the continued employment of the recipient through the remainder of the applicable performance period and is paid out at the end of the performance period, subject to acceleration of vesting upon a qualifying termination, in which event the units are distributed at that time. Notwithstanding the foregoing, in the event that both a change in control occurs and the acquirer refuses or is unable to agree to the foregoing conversion and vesting provisions, the award will be vested at the time of the change in control, and will be distributed in accordance with the provisions of Code Section 409A, to the extent applicable. The agreements have been drafted to provide that in such event distribution may be in cash. Stock Options.If the executive dies or becomes disabled, the executive’s outstanding stock options become vested and may be exercised until the earlier of five years following death or disability or the expiration date of the option. If the executive retires, or if the executive is a member of the Management Group on the date of grant, is age 55 or older with a minimum of 10 years of employment on the date of termination of employment, and is not otherwise retirement-eligible pursuant to the Corporation’s retirement policy, the stock options continue to vest in accordance with their terms and, once vested, may be exercised until the earlier of five years following retirement or the expiration date of the option. If the executive’s employment is terminated under certain circumstances entitling the executive to severance benefits, the executive’s stock options (whether vested or unvested) may be exercised until the earlier of 180 days following termination of employment or the expiration date of the option, provided that if the executive is retirement eligible upon his or her termination of employment under the severance plan, the executive’s stock options (whether vested or unvested) become vested upon the executive’s termination of employment and may be exercised until the earlier of five years from the executive’s effective date of retirement or the expiration of the option. In addition, subject to certain conditions, Management Group members who hold options granted in 2012 are eligible for accelerated vesting upon termination of employment to commence government service (or upon acceptance of government employment after termination of employment with the Corporation but prior to a vesting date) in instances where divesture of equity interests in the Corporation is required by law or is otherwise reasonably necessary, and may exercise their options for 90 days following their government service termination date or commencement of government employment, as applicable, or until the expiration of the option, if earlier. In other instances, in the absence of a change in control, vested stock options expire on the earlier of three months following termination of employment or the expiration date of the option, and unvested stock options expire on termination of employment. Upon a change in control of the Corporation, all stock options granted prior to December 31, 2012, become vested and exercisable. Stock options granted after December 31, 2012, convert to options on stock of the acquirer and continue to vest in accordance with the regular vesting schedule, provided, however, that they become fully vested in connection with a change in control if the executive experiences a qualifying termination of employment following the change in control (in which case the options on the acquirer stock remain exercisable until the expiration of the option), or if they are not assumed in the transaction (in which case the employee is entitled to a cash payment equal to the “spread” between the transaction consideration and the option exercise price). The Corporation’s equity award agreements contain provisions related to a change in control of the Corporation. In the absence of an employment security agreement, the provisions of the equity award agreements provide for the same accelerated vesting of equity awards as outlined above in the discussion of employment security agreements. Therefore, in the event of a change in control, absent an employment security agreement, the value of all fully vested equity awards would be the same as reported for a termination of the named executive’s employment related to a change in control under the employment security agreement. Assuming, in the absence of a change in control, a termination of the named executive officer’s employment due to death, disability, or retirement (including termination while a member of the Management Group at age 55 with the requisite service) occurred on December 31, 2010,2012, stock options under the equity compensation plans would have accelerated or continued vesting and the value of these fully vested stock options would be the same as reported for a termination related to a change in control under the employment security agreements. Absent a change in control, in the event of a termination of a named executive officer’s employment due to death, disability or retirement (including termination in circumstances in which the executive is entitled to severance or while a member of the Management Group at age 55 with the requisite service) on December 31, 2010,2012, equity award agreements for restricted stock units and performance stock units provide for prorated vesting of units. The value of these prorated units for each named executive officer is:   Mr. Waddell:    $ 1,678,092       (restricted stock units)    $ 5,270,612       (restricted stock units)      —         (performance stock units)    $ 819,313       (performance stock units) Mr. Morrison:    $ 521,629       (restricted stock units)    $ 1,782,034       (restricted stock units)      —         (performance stock units)    $ 409,657       (performance stock units) Ms. Barrat:    $ 521,629       (restricted stock units) Mr. O’Grady:    $ 471,604       (restricted stock units)      —         (performance stock units)    $ 245,784       (performance stock units) Mr. Fradkin:    $ 521,629       (restricted stock units)    $ 1,604,368       (restricted stock units)      —         (performance stock units)    $ 245,784       (performance stock units) Ms. Schreuder:    $ 521,629       (restricted stock units)    $ 1,604,368       (restricted stock units)      —         (performance stock units)    $ 245,784       (performance stock units) The value of the prorated restricted stock units and performance stock units is also based on the $55.41$50.16 closing market price.price on December 31, 2012. Unlike the valuations in the change in control context, these estimated values assume a prorated distribution (rather than full distribution) of restricted stock units and performance stock units and the proration for performance stock units is based on the target number versus a maximum performance assumption. In January 2011, performance stock units granted in 2008 and included in the value of prorated performance stock units above were cancelled as a result of failure to meet minimum performance goals for the three-year period ending December 31, 2010. No unvested performance stock units remained following cancellation of the 2008 awards.units.

See footnote 22 to the Consolidated Financial Statements contained in the Corporation’s 2010 Annual Report2012 annual report to Stockholdersstockholders for a discussion of the assumptions made by the Corporation in the valuation of these restricted stock unit awards. As of December 31, 2010,2012, each non-employee director (other than Messrs. Kelly and H.B. Smith, who retired as members of the Board effective April 20, 2010)Mr. Prado) held 1,625.431,920.20 unvested stock units, which, as described below, represented the stock unit award made by the Corporation in February 2010.2012. As of December 31, 2012, Mr. Prado held an aggregate of 946.77 unvested stock units, which, as described below, represented the stock unit awards made by the Corporation on October 16, 2012 as part of Mr. Prado’s compensation for services as a non-employee director from October 16, 2012 through December 31, 2012. (2)All Other Compensation. Perquisites paid or provided to directors in 20102012 were less than the SEC’s minimum threshold for disclosure ($10,000). (3) Messrs. Kelly and H.B. Smith retired as members of the Board effective April 20, 2010. (4) Mr. D.H.B. Smith, Jr.Prado became a member of the Boardboard effective April 20, 2010.October 16, 2012. General Directors who are employees of the Corporation receive no additional compensation for serving on the board of directors or on any board committee. 20102012 Director Compensation 2012 director compensation was unchanged from 2011. Cash Compensation. In 2010,2012, non-employee directors of the Corporation received the following cash compensation for their service on the board of directors:   Annual Retainer   $ 90,000    Additional Fee for the Chairman of each Board Committee (other than the Executive Committee)   $ 15,000    Additional Fee for Audit Committee Members (including the Chairman)   $ 5,000    Additional Fee for Lead Director   $ 15,000    All non-employee directors also are eligible to receive a per diem fee of $1,000 when required to attend orientation meetings or to perform specific services on behalf of the Corporation. The Corporation paid $12,000$2,000 for such services in 2010.2012. Equity Compensation. In February 2010,2012, each non-employee director then in office received a grant of stock units under the Corporation’s 20022012 Stock Plan equal in value to $90,000, with the actual number of stock units (1,625.43 stock units) based on the closing sale price of the common stock on the date of the 20102012 annual meeting of stockholders. Mr. Prado, who became a non-employee director of the Corporation effective October 16, 2012, received a grant of stock units on October 16, 2012, equal in value to $45,000, an amount equal to the portion of $90,000 prorated from October 16, 2012, with the actual number of stock units (946.77 stock units) based on the closing sale price of the common stock on October 16, 2012. All of the stock units granted to directors in February 20102012 and the award granted to Mr. Prado on October 16, 2012 will vest on the date of the 20112013 annual meeting of stockholders. Stock units do not have voting rights. Dividend equivalents on the non-employee directors’ stock units are subject to the same vesting, forfeiture, and distribution provisions as the underlying stock units. Each stock unit entitles a director to one share of common stock at vesting, unless a director elects to defer receipt of the shares. Stock Ownership Guidelines. As described in the Compensation Discussion and Analysis section, Northern Trust has a long-standing practice of emphasizing stock ownership and maintaining formal stock ownership guidelines for named executive officers. Northern Trust also maintains formal stock ownership guidelines for its non-employee directors with minimum ownership levels as shown in the following chart. Stock Ownership Guidelines for Non-Employee Directors Non-Employee Directors Expected to maintain minimum share ownership levels to a value of five times annual cash retainer It is expected that each non-employee director will meet the minimum ownership level not later than five years from the date the director is initially elected to the board. In addition, non-employee directors are expected to meet a minimum share ownership level of 1,000 shares within one year from the date they are initially elected to the board. Until such time as any non-employee director meets the minimum ownership level requirement, he or she is expected to retain 100% of the net, after-tax shares received from share distributions. The calculation of shares of common stock includes shares that are: — Purchased on the open market — Owned jointly with or separately by spouse and children — 100% of unvested (or vested but not yet distributed) RSUs, stock awards and deferred stock units — 100% of cash compensation deferred as stock equivalent units As of December 31, 2013, all non-employee directors met or exceeded Northern Trust’s stock ownership guidelines. Consistent with those guidelines, Mr. Slark and Mr. Prado, who were first elected to the Corporation’s board of directors on April 19, 2011 and October 16, 2012, respectively, have five years from the date elected to reach the share ownership threshold level set forth in the chart above. 20112013 Director Compensation Effective as of January 1, 2013, the Corporation increased the annual retainer and the value of stock units granted under the Corporation’s 2012 Stock Plan to $100,000 each and the additional annual retainer for the Lead Director to $25,000. All other non-employee director compensation for 2011in 2013 will remain the same as it was in 2012. In approving the foregoing increases, the Compensation and Benefits Committee and the Board considered, among other things, competitive director compensation data, current market practices, and the fact that non-employee director compensation had remained the same since January 1, 2010. Deferral of Compensation Non-employee directors may elect to defer payment of their cash compensation and stock units until termination of their service as directors. Any deferred cash compensation is converted into stock units representing shares of common stock. The value of each such stock unit is based upon the market price of the stock at the end of the calendar quarter for which the cash compensation would have been paid. Dividend equivalents on all deferred stock units are paid quarterly to a cash account and accrue interest at an interest rate determined from time to time by the Committee. Deferred cash compensation and dividend equivalents will be paid out in cash, and deferred stock units will be distributed in stock, in each case in a lump sum or in up to 10 annual installments at the election of the director.

These stock units have been deferred at the election of certain directors and will be distributed on a one-for-one basis in shares of common stock following retirement. ITEM 2—ADVISORY VOTE ON EXECUTIVE COMPENSATION Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC enacted requirements for the Corporation to include in this proxy statement a separate resolution, subject to an advisory vote, to approve the compensation of our named executive officers. This proposal is commonly referred to as a “Say on Pay” proposal. As required by these rules, we are asking you to vote FOR the adoption of the following resolution: “Resolved, that the compensation paid to the Corporation’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K of the Securities Exchange Act of 1934, including the Compensation Discussion and Analysis, compensation tables, and narrative discussion, is hereby APPROVED.” As an advisory vote, this proposal is not binding on the Corporation. Although the vote is non-binding, the board of directors and the Compensation and Benefits Committee value the opinions of our stockholders and will consider the outcome of the vote when making future compensation decisions for our named executive officers. As outlined in the Compensation Discussion and Analysis that begins at page 28,30, the Corporation has a conservative performance-based compensation system in place that provides appropriate levels of compensation. The Corporation’s executive compensation program is designed to attract, motivate, and retain individuals who will contribute to the Corporation’s success and the creation of stockholder value. The Compensation and Benefits Committee believes that executive officers are best motivated when their incentive compensation is tied to the Corporation’s overall performance and the performance of their individual business units and/or individual performance. That is why a significant portion of each executive officer’s short-term and long-term cash and equity compensation is variable and depends on such performance. In addition, our emphasis on equity-based compensation discourages inappropriate risk-taking and encourages named executive officers to appropriately consider and control risk factors, which furthers the Corporation’s risk-mitigation strategy. In February 2013, the Corporation enhanced the risk-related forfeiture and clawback provisions in certain equity awards to further align those provisions with regulatory guidance and shareholder interests. The Corporation also hasreported 2012 net income of $687.3 million, diluted earnings per share of $2.81 and a recordpre-tax profit margin of strong performance.25.5%. The Corporation’s 5-year compound annual growth rates for Net Income2012 return on equity increased to 9.3%, consistent with, although slightly lower than, its peer group median of 9.6% and Diluted Earnings Per Share are 2.8%in line with its trust and 0.7%, respectively. In comparison,custody bank peers. For the average 5-year compound annual growth rates of Net Income and Diluted Earnings Per Share for the 20 largest banks in the U.S. (excluding the Corporation), as sourced from SNL Financial, are -1.8% and -9.2%, respectively. The Corporation’s long-term stock price performance also compares favorably with other banks and financial institutions. It has been the second best performing stock of the 20 largest banks for the 5-year period from December 30, 2005 throughending December 31, 2010, as sourced from NASDAQ. The2012, the Corporation’s 5-year compound annual growth rate for its stock is 1% as compared to -13% foraverage three and five year returns on equity were 9.3% and 11.3%, respectively, higher than the KBW Bank Index (24 major U.S. banks)peer group medians of 8.5% and 0% for the S&P 500.4.5%, respectively. Despite the prolonged weakness in economic conditions that have particularly affected the financial performance of banks and other financial institutions, the Corporation’s conservatively managed executive compensation philosophy, coupled with its sound balance sheet and prudent business model, have contributed to the Corporation’s strong strategic and financial positioning. The board of directors unanimously recommends that you voteFOR this proposal. ITEM 3—ADVISORY VOTE ON FREQUENCY OF SAY ON PAY VOTE The “Say on Pay” rules also require the Corporation to include in this proxy statement a separate resolution subject to an advisory vote as to whether the Corporation should hold an advisory vote on executive compensation every one, two or three years. Please mark your proxy card to indicate your preference on this proposal by indicating whether the Corporation should hold an advisory vote on executive compensation every one, two, or three years or your abstention if you wish to abstain. As an advisory vote, this proposal is not binding on the Corporation. Although the vote is non-binding, the board of directors and the Compensation and Benefits Committee value the opinions of our stockholders and will consider the outcome of the vote when determining the frequency at which to hold an advisory vote on executive compensation. After considering the benefits and consequences of each option for the frequency of submitting the advisory vote on executive compensation to stockholders, the board of directors recommends submitting the advisory vote on the compensation of our named executive officers to our stockholders annually. We believe an annual advisory vote on the compensation of our named executive officers will allow us to obtain information on stockholders’ views of the compensation of our named executive officers on a more consistent basis. In addition, we believe an annual advisory vote on the compensation of our named executive officers aligns more closely with our objective to engage in regular dialogue with our stockholders on corporate governance matters, including our executive compensation philosophy, policies, and programs. The board of directors unanimously recommends that you select1 YEAR for this proposal. AUDIT COMMITTEE REPORT The Audit Committee of the board is responsible for providing oversight of the Corporation’s financial reporting functions and internal controls. The board appoints the Audit Committee and its chairman annually, with the Committee consisting of at least four directors. The Audit Committee operates under a formal charter, which is available on the Corporation’s website at www.northerntrust.com. The Audit Committee charter sets forth in detail the duties and responsibilities of the Audit Committee. The Audit Committee’s duties and responsibilities are ones of oversight. In fulfilling their duties and responsibilities, it is recognized that members of the Committee are not full-time employees of the Corporation, and are not, and do not represent themselves to be, accountants or auditors by profession. Each member of the Committee shall be entitled to rely in good faith on (i) the integrity of those persons and organizations within and outside the Corporation from which he or she receives information, (ii) the accuracy of the financial and other information provided to the Committee absent actual knowledge to the contrary (which shall be promptly reported to the board), and (iii) representations made by management or third parties as to any information technology, internal audit, and other non-audit services provided by the Corporation’s independent registered public accountants to the Corporation. The responsibility for the completeness and accuracy of the Corporation’s consolidated financial statements rests with the Corporation’s management. The responsibility of KPMG LLP, the Corporation’s independent registered public accounting firm, is (i) to perform an audit and to express an opinion as to whether the Corporation��sCorporation’s annual consolidated financial statements are free of material misstatement and presented in accordance with generally accepted accounting principles and (ii) to perform an audit and to express an opinion as to whether the Corporation maintained effective operation of the Corporation’s internal control over financial reporting. The Audit Committee received the written disclosures and the letter from KPMG LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding KPMG LLP’s communications with the Audit Committee concerning independence. The disclosures described the relationships and fee arrangements between the firm and the Corporation. Consistent with the applicable requirements of the Public Company Accounting Oversight Board and the rules and regulations of the SEC, the Audit Committee considered at meetings held on January 17, 2011 and February 14, 201111, 2013 whether the provision of non-audit services by the independent registered public accounting firm to the Corporation for the fiscal year ended December 31, 20102012 maintains KPMG LLP’s independence and has discussed with KPMG LLP the firm’s independence from the Corporation. The Audit Committee reviewed and discussed with the Corporation’s independent registered public accounting firm the matters required to be discussed by the Statement on Auditing Standards No. 114, The Auditor’s Communication With Those Charged With Governance (which replaced Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended by SAS No. 90 Audit Committee Communications).Committees. The Audit Committee reviewed and discussed with management and the Corporation’s independent registered public accounting firm the consolidated financial statements of the Corporation for the year ended December 31, 2010.2012. Based on the above-mentioned reviews and discussions with management and the Corporation’s independent registered public accounting firm, and subject to the limitations on the role and responsibilities of the Audit Committee referred to above, the Audit Committee, exercising its business judgment, recommended to the board that the Corporation’s audited consolidated financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2010,2012, for filing with the SEC. This report is submitted on behalf of the members of the Audit Committee: Edward J. Mooney, Chairman, Linda Walker Bynoe, Nicholas D. Chabraja, Robert W. Lane, Robert C. McCormackand David H. B. Smith, Jr. ITEM 4—3—RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Appointment of Independent Registered Public Accounting Firm The independent registered public accounting firm is appointed annually by the Corporation’s Audit Committee. For the year ending December 31, 2011,2013, the Audit Committee has authorized the engagement of KPMG LLP as the Corporation’s independent registered public accounting firm. KPMG LLP served as the Corporation’s independent registered public accounting firm for the fiscal year ended December 31, 2010.2012. Representatives of KPMG LLP will be present at the annual meeting. They will have an opportunity to make a statement if they wish and will be available to respond to appropriate questions raised by stockholders at the meeting. Stockholder ratification of the selection of KPMG LLP as the Corporation’s independent registered public accounting firm is not required. However, the board of directors is submitting the selection of KPMG LLP as the Corporation’s independent registered public accounting firm to the stockholders for ratification to learn the opinion of stockholders on this selection. If the stockholders fail to ratify KPMG LLP as the independent registered public accounting firm, the Audit Committee will reassess its appointment. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of the Corporation and its stockholders.

(2) Includes fees for services that were reasonably related to performance of the audit of the annual consolidated financial statements for the fiscal year, other than Audit Fees, such as employee benefit plan audits and internal control reviews. (3) Includes fees for tax return preparation and tax planning. (4) Includes fees for all services other than Audit Fees, Audit-Related Fees, and Tax Fees. (5) Additional Fees are fees for services rendered in connection with audits for certain of the proprietary, common and securities lending collateral funds sponsored or managed by the Corporation. These funds are not included in the consolidated financial statements of the Corporation. Pre-Approval Policies and Procedures of the Audit Committee On October 19, 2009, the Audit Committee adopted the revised Northern Trust Corporation Policy Regarding Engagement of Independent Public Accounting Firm to Provide Auditor Services, which superseded the Policy adopted by the Audit Committee on October 20, 2008. The purpose of the Policy is to establish procedures for Audit Committee pre-approval of all auditor services to be provided to the Corporation by its independent registered public accounting firm. Auditor services include audit services, audit-related services, tax services, and non-audit services. The Policy provides that the Audit Committee, the Chairman, or any Audit Committee member delegated the authority (a “Designated Member”) has the authority to grant pre-approvals of auditor services. In addition, the Policy provides that the independent registered public accounting firm may be engaged to provide only those non-audit services (i) that are permitted by the SEC’s final rule entitled “Strengthening the Commission’s Requirements Regarding Auditor Independence” and (ii) that, in the judgment of the Audit Committee, maintain the independent registered public accounting firm’s independence from the Corporation. In evaluating whether a proposed engagement of the Corporation’s independent registered public accounting firm for a specific permitted non-audit service maintains the firm’s independence from the Corporation, the Audit Committee or a Designated Member thereof must consider whether the proposed engagement would cause the independent registered public accounting firm to (1) audit its own work, (2) perform management functions, or (3) act as an advocate for the Corporation. The independent registered public accounting firm shall in no event be engaged to perform any Prohibited Services, as defined in the Policy. The following percentages of the Audit-Related Fees, Tax Fees, and Other Fees were approved in accordance with the exceptions to pre-approval requirements set forth in 17 CFR 210.2-01(c)(7)(i)(C): For the fiscal year ended December 31, 2010,2012, Audit-Related Fees: 0%, Tax Fees: 0%, and Other Fees: 0%. The board of directors unanimously recommends that you voteFOR the ratification of KPMG LLP as the Corporation’s independent registered public accounting firm for the fiscal year ending December 31, 2011.2013. ITEM 4—STOCKHOLDER PROPOSAL REGARDING ADDITIONAL DISCLOSURE OF POLITICAL AND LOBBYING CONTRIBUTIONS Information regarding a stockholder proposal is set forth below. The Corporation disclaims any responsibility for the content of this proposal and statement of support, which is presented as received from the stockholder. The Massachusetts Laborers’ Pension Fund, 14 New England Executive Park, Suite 200, Burlington, Massachusetts 01803-5201, the owner of approximately 13,250 shares of our common stock, has given the Corporation notice that its representative intends to present this proposal at the annual meeting. Stockholder Proposal: RESOLVED, that the shareholders of Northern Trust Corporation (“Northern Trust” or “Company”) hereby request that the Company provide a report, updated semi-annually, disclosing the amounts that the Company has paid or incurred in connection with influencing legislation; participating or intervening in any political campaign on behalf of (or in opposition to) any candidate for public office; and attempting to influence the general public, or segments thereof, with respect to elections, legislative matters or referenda. The report should include (a) contributions to or expenditures on behalf of political candidates, political parties, political committees and other political entities and (b) the portions of any dues or other payments that are made to a tax-exempt organization for an expenditure or contribution that, if made directly by the Company, would not be deductable under section 162(e)(1) of the Internal Revenue Code. The report should identify each recipient, the amount paid to each, and the purpose of any contribution or expenditure. STOCKHOLDER SUPPORTING STATEMENT As long-term shareholders of Northern Trust, we support transparency and accountability in corporate spending on lobbying and political activities. The expenditures upon which we seek a report are those that Congress has said do not warrant a deduction as an ordinary and necessary business expense, namely, lobbying, participation in the political system by supporting or opposing candidates for office, and trying to influence the general public or segment thereof as to elections, legislative matters or referenda. This includes payments to third parties, including trade associations and other tax-exempt groups, which payments are used for expenditures that would not be deductible if made by the company itself. Disclosure is consistent with public policy and we believe, in the best interest of the company and its shareholders. The Supreme Court’s Citizens United decision recognized the importance of political spending disclosure when it said “[D]isclosure permits citizens and shareholders to react to the speech of corporate entities in a proper way. This transparency enables the electorate to make informed decisions and give proper weight to different speakers and messages.” Gaps in transparency and accountability may expose the company to reputational and business risks that could threaten long-term shareholder value. Moreover, publicly available data does not provide a complete picture of the Company’s lobbying or political expenditures. Thus the Company’s payments to trade associations for these purposes are undisclosed and unknown, as are any payments to tax-exempt groups that work to influence legislation and political campaigns, as well as public opinion that could affect legislation or elections. The sums involved can be significant. A 2010 Bloomberg story reported that several health insurers donated $86.2 million to the U.S. Chamber of Commerce in 2009-10 for advertisements, polling and grassroots events to drum up opposition to health care reform legislation. A former Federal Election Commission chairman described this figure as “breathtaking”. We believe that shareholders need improved disclosure in order to fully evaluate the use of corporate assets on these activities. Statement of the Board of Directors in Opposition to the Shareholder Proposal THE BOARD OF DIRECTORS BELIEVES THAT THE PROPONENT’S PROPOSAL IS NOT IN THE BEST INTERESTS OF NORTHERN TRUST AND ITS SHAREHOLDERS AND RECOMMENDS A VOTE “AGAINST” THE PROPOSAL. As a leading provider of asset servicing, fund administration, asset management, fiduciary, and banking solutions for corporations, institutions, families, and individuals worldwide, Northern Trust is extensively regulated. Changes in the legal and regulatory environment for financial institutions may substantially impact the manner in which Northern Trust and its subsidiaries operate, serve their clients, and create value for shareholders. We believe it is in the best interests of Northern Trust’s shareholders for Northern Trust to support positions that enhance the safety of client assets and promote the safety and soundness of the financial system and a strong global economy. The potential impact that public policy changes can have on our business, employees, communities, clients, and shareholders requires us to be an active participant in the political process to advance and protect the long-term interests of Northern Trust. Northern Trust’s philosophy and policies concerning political contributions and legislative lobbying are set forth in our “Statement Regarding Government Relations and Political Contributions,” which can be found on our public web site at http://www.northerntrust.com/about-us/investor-relations/corporate-governance/government-relations-political-contributions. Northern Trust contributes to candidates for public office and related organizations in compliance with applicable law. Northern Trust sponsors a political action committee, known as a PAC, which allows certain U.S. employees to pool their financial resources to support United States federal and state candidates who support legislation important to Northern Trust and its shareholders. All contributions to the PAC are voluntary. The PAC determines all political contributions based on the best interests of Northern Trust. Northern Trust also contributes to certain industry trade organizations relating to its public policy objectives. We believe that the additional disclosure sought by the proposal would be of no appreciable benefit to shareholders. As required by law, all Northern Trust’s PAC contributions are reported on a periodic basis to the Federal Election Commission and appropriate state election authorities. A direct link to Federal Election Commission reports is included in Northern Trust’s publicly available “Statement Regarding Government Relations and Political Contributions” and annual “Corporate Social Responsibility Report.” In addition, Northern Trust is required to comply with United States federal and state laws and regulations regarding the disclosure of certain lobbying activities. All such disclosures of Northern Trust’s lobbying activities are already publicly available. The Board of Directors believes that in light of the fact that Northern Trust already provides all legally required disclosures regarding political contributions and lobbying activities and the fact that much of this information is already publicly available, this proposal is duplicative and unwarranted, and would cause the Corporation to expend unnecessary time and resources without providing any appreciable benefit to shareholders. FOR THE ABOVE REASONS, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “AGAINST” THE PROPOSAL. OTHER BUSINESS The board of directors knows of no business to be presented at the 20112013 annual meeting other than that described above. The Corporation’s by-laws provide that stockholders may bring matters before an annual meeting only if they give timely written notice of the matter to be brought not less than 120 days prior to the anniversary date of the prior year’s annual meeting. The notice must be directed to the attention of the Corporation’s Corporate Secretary and contain the information required by the Corporation’s by-laws. STOCKHOLDER PROPOSALS FOR 20122014 ANNUAL MEETING Any stockholder proposals for the 20122014 annual meeting must be received by the Corporation, directed to the attention of the Corporation’s Corporate Secretary, no later than November 14, 20117, 2013 in order to be eligible for inclusion in the Corporation’s proxy statement and form of proxy for that meeting. The proposal must comply in all respects with the rules and regulations of the SEC and the Corporation’s by-laws. Also, under the Corporation’s by-laws, other proposals that are not included in the proxy statement will be considered timely and may be eligible for presentation at that meeting if they are received by the Corporation in the form of a written notice, directed to the attention of the Corporation’s Corporate Secretary, not later than December 20, 2011.17, 2013. The notice must contain the information required by the Corporation’s by-laws. By Order of the Board of Directors, By Order of the Board of Directors, Rose A.
