PROXY STATEMENT

INTRODUCTION

Our 2008 annual meeting of stockholders will be held on Tuesday, April 15, 2008 at 10:30 a.m., Chicago time, at the office of Northern Trust Corporation (the “Corporation”) located on the northwest corner of LaSalle Street and Monroe Street in Chicago, Illinois. 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 10, 2008, 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 2007 annual report to stockholders, which consists of the 2007 summary annual report and the 2007 financial annual report. These reports contain detailed information about the Corporation’s activities and financial performance in 2007.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE STOCKHOLDER MEETING TO BE HELD ON APRIL 15, 2008

This proxy statement and the 2007 annual report to stockholders, which consists of the 2007 summary annual report and the 2007 financial annual report, are available at http://ww3.ics.adp.com/streetlink/NTRS1.

VOTING

Who May Vote

Record holders of the Corporation’s common stock at the close of business on February 25, 2008 may vote at the annual meeting. On that date, the Corporation had 220,576,531 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 25, 2008. 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 proxy 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;

—

Using the Internet site listed on the proxy card; or

—

Completing, signing, dating, and returning the proxy card in the postage-paid envelope provided.

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.

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:


Item 1	—	FOR the election of each nominee for director; and

Item 2	—	FOR the ratification of the appointment of KPMG LLP as the Corporation’s independent registered public accounting firm for the fiscal year ending December 31, 2008.

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 time before it is voted at the annual meeting by:

—

Sending a written notice of revocation to the Corporate Secretary at the address indicated on the first page of this proxy statement;

—

Submitting another signed proxy card with a later date;

—

Voting by telephone or through the Internet at a later date; or

—

Attending the annual meeting and voting in person.

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 25, 2008, 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. 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.


Item	Required Vote	Effect of “Withhold” Votes, Abstentions, Broker Non-Votes

Item 1—Election of Directors	Affirmative vote of a majority of the shares of common stock present in person or by proxy and entitled to vote.	—“Withhold” votes will have the effect of a vote AGAINST the election of directors. —Broker non-votes will have no effect on the voting for the election of directors.

Item 2—Ratification of the appointment of KPMG LLP as the Corporation’s independent registered public accounting firm for fiscal year 2008	Affirmative vote of a majority of the shares of common stock present in person or by proxy and entitled to vote.	—Abstentions will have the effect of a vote AGAINST ratification. —Broker non-votes will have no effect on the vote for ratification.

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 $12,500, 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 15, 2008, 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 your admission ticket, 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 14 directors at this year’s annual meeting. Set forth below is detailed information with respect to the 14 nominees, all of whom are currently serving as directors of the Corporation and of its principal subsidiary, The Northern Trust Company (the “Bank”). The board of directors approved the slate of 14 nominees based on consideration of the factors specified in the Corporate Governance Guidelines and the recommendation of the Corporate Governance Committee.

Each of the 14 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 Restated Certificate of Incorporation, 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 vote FOR the election of each nominee.

Meetings

The Corporation’s board of directors held six meetings during 2007. All persons who were directors during 2007 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 2007 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 2007 (including Duane L. Burnham, who retired from the board of directors on April 17, 2007) and each director nominee for 2008 (other than William A. Osborn, the Chairman of the Corporation and the Bank, and Frederick H. Waddell, the Chief Executive Officer and President of the Corporation and the Bank) are “independent” directors as defined under applicable Nasdaq rules. In making its determinations of independence, the board considered certain categorical standards of independence as set forth in stock exchange corporate governance rules 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 2007 (including Mr. Burnham) or director nominee for 2008 either (i) directly or (ii) indirectly through an immediate family member of the director or director nominee, or an entity in which the director or director nominee is employed or is a general partner or principal or in a similar position or in which the director or director nominee and all other “related persons” (as defined below under “—Related Person Transaction Policy”) has a 10% or greater beneficial ownership interest (all relationships under (i) and (ii), collectively, the “Relationships”). In 2007, these Relationships included:

—

The Corporation’s payment for electric utility services provided directly or indirectly to the Corporation by a subsidiary of Exelon Corporation, at which Director Rowe serves as Chairman, President and Chief Executive Officer;

—

The Corporation’s payment of underwriting discounts and receipt of referral fees under agreements with Loop Capital Markets, LLC, at which Director Bynoe’s husband became a Managing Director in January 2008;

—

The Corporation’s contribution of conference sponsorship fees to Kellogg School of Management, Northwestern University, at which Director Jain serves as Dean; and

—

The following types of services provided by the Corporation or its subsidiaries in the ordinary course of business in connection with the Relationships (as identified by the name of the applicable former director, current director, or director nominee):


Trust and related services		Burnham, Bynoe, Kelly, McCormack, Mooney, Rowe, Smith
Credit services and other banking services (e.g., deposits, checking, treasury management)		Burnham, Bynoe, Chabraja, Crown, Jain, Kelly, McCormack, Mooney, Rowe, Smith, Smithburg
Investment management and related services		Kelly, McCormack, Mooney, Rowe, Smith
Asset servicing and related services		Chabraja, McCormack, Rowe, Smith
Qualified retirement plan services		Chabraja, Smith
Brokerage services		Bynoe, Chabraja, Jain, McCormack, Rowe, Smith, Smithburg
Securities lending, foreign exchange, and related services		Chabraja, Rowe, Smith

In each case, the Corporation’s directors and director nominees, other than Mr. Osborn and Mr. Waddell, could be determined to be independent under the categorical standards considered by the board, which are attached as Exhibit A to this proxy statement. A copy of the categorical standards is also available on the Corporation’s website at www.northerntrust.com.

Executive Sessions

The independent directors of the Corporation meet in executive sessions separate from management at least twice a year. The independent directors met in such executive sessions six times during 2007. The chairman of the Corporate Governance Committee or, in his or her absence, the chairman of the Audit, Compensation and Benefits, Business Risk, or Business Strategy Committee presides at the 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 November 2007. 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.

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 90 days and not more 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.” The Committee uses the same process for considering, evaluating, and recommending director candidates, regardless of whether a candidate is recommended by a stockholder, director, officer, third-party search firm, or any other person or group.

In its evaluation of director candidates, including persons recommended by stockholders, the Committee considers the factors specified in the Corporation’s Corporate Governance Guidelines, 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 individual 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.

Related Person Transaction Policy

The board of directors of the Corporation, through its Audit Committee, has adopted the “Northern Trust Corporation Policy and Procedures with Respect to Related Person Transactions” (the “RPT Policy”), which was most recently revised in February 2008. The RPT Policy governs the review, approval, or ratification of transactions between the Corporation or its subsidiaries and any related persons. “Related persons” means the Corporation’s directors, nominees for director, executive officers, greater than five percent beneficial owners, members of their immediate family, and any firm, corporation, or other entity in which any of the foregoing persons is employed or is a general partner or principal or in a similar position or in which such person and all other related persons has a 10% or greater beneficial interest.

The RPT Policy provides that the Corporation may undertake certain pre-approved related person transactions in the ordinary course of business without specific review, approval or ratification, including the following pre-approved transactions:

—

An extension of credit to a related person that is made in the ordinary course of business on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the lender and does not involve more than the normal risk of collectibility or present other unfavorable features;

—

Certain other ordinary course transactions in which the Corporation or its subsidiaries provide products or services to related persons on terms no less favorable to the Corporation and its subsidiaries as those prevailing at the time for comparable services to non-related persons;

—

A transaction involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services;

—

A transaction where the rates or charges involved in the transaction are determined by competitive bids, or the transaction involves the rendering of services as a common or contract carrier, or public utility, at rates or charges fixed in conformity with law or governmental authority;

—

A transaction with another company at which a related person’s only relationship is as an employee, a limited partner or a beneficial owner of less than 10% of the company’s

outstanding common equity, provided the aggregate amount of the transaction does not exceed the greater of $1 million or 2% of the other company’s annual revenues;

—

Certain charitable contributions, grants or pledges of grants or contributions to organizations for which a related person serves as an executive officer where the aggregate amount of the transaction does not exceed the lesser of $1 million or 2% of the organization’s total annual receipts;

—

Transactions where the related person’s interest arises solely from the ownership of the Corporation’s common stock and all stockholders receive the same benefit on a pro rata basis; and

—

Compensation paid to executive officers and directors of the Corporation that is reported in the Corporation’s proxy statement or otherwise approved or recommended by the Compensation and Benefits Committee.

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. In addition, the RPT Policy provides that (i) no immediate family member of an executive officer (other than a child, stepchild or parent of an executive officer, none of whom may be hired under the Corporation’s human resources policies) shall be hired by the Corporation and (ii) no immediate family member of a director shall be hired by the Corporation, in each case, unless the employment arrangement is reviewed and approved by the Compensation and Benefits Committee.

In 2007, directors, director nominees, and executive officers of the Corporation, as well as their immediate family members, and any firm, corporation, or other entity in which the director, director nominee, or executive officer is employed or is a general partner or principal or in a similar position or in which the director, director nominee, or executive officer and all other related persons has a 10% or greater beneficial ownership interest, were clients of, and engaged in the types of transactions identified in the bullet points above with, the Corporation and its subsidiaries. These transactions were undertaken in the ordinary course of business and on terms no less favorable to the Corporation and its subsidiaries as those prevailing at the time for comparable transactions with non-related persons. None of these transactions or any transactions in which the Corporation or its subsidiaries sold or purchased products and services were material to the Corporation or the other entity involved. Any extensions of credit to directors and executive officers of the Corporation were permitted under the provisions of the Sarbanes-Oxley Act of 2002.

Compensation and Benefits Committee Interlocks and Insider Participation

The Compensation and Benefits Committee of the board of directors consists of Directors Crown (Chair), McCormack, Mooney, Smithburg, and Tribbett. None of the members of the Compensation and Benefits Committee is or ever was an officer or employee of the Corporation or any of its subsidiaries.

COMPENSATION DISCUSSION AND ANALYSIS

EXECUTIVE COMPENSATION PHILOSOPHY

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 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 cash compensation (base salaries and annual cash incentives), equity compensation (stock options, restricted stock units, and performance stock units), and retirement benefits. In establishing total compensation, the Corporation focuses primarily upon annual cash incentives and equity compensation, with base salary constituting a smaller relative portion of the overall compensation opportunity of the named executive officers.

Cash compensation rewards short-term performance, typically the achievement of annual financial and non-financial goals of the Corporation. The Corporation uses equity compensation to help 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 company, business unit, and individual performance by differentiating the awards made to individual executives. The retirement program provides post-employment financial security based on length of service by executives and other employees with the Corporation.

The Corporation has adopted the following criteria in the design of its executive compensation program:

—

Executive compensation should be “performance based.” Significant short-term and longer-term financial rewards are linked to the Corporation’s success as defined by certain financial goals. A significant portion of the executive officers’ cash and equity compensation is variable and depends on company, business unit, and/or individual performance. This component of executive compensation increases if performance goals are achieved or exceeded and, correspondingly, decreases if performance goals are not achieved.

—

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. The use of restricted stock units, performance stock units, and stock options is designed to encourage and motivate executive officers to act as owners with an equity stake in the Corporation.

—

Executive compensation should be “competitive.” The Corporation’s executive compensation program is designed to compensate individuals at levels that are competitive with similar positions to those in a peer group of financial services organizations, adjusted as necessary to reflect the relative financial and operating performance of the Corporation and these peer organizations. For 2007, the 12 companies comprising the Corporation’s peer group were:

— The Bank of New York Company, Inc.*

— Fifth Third Bancorp

— Comerica Incorporated

— Key Corp

— Mellon Financial Corporation*

— The PNC Financial Services Group Inc.

— SunTrust Banks, Inc.

— Wachovia Corporation

— National City Corporation

— State Street Corporation

— U.S. Bancorp

— Wells Fargo & Company

* Effective July 1, 2007, these two companies merged to form The Bank of New York Mellon Corporation.

All of these companies are included in the Keefe, Bruyette & Woods Bank Index, a market-capitalization-weighted bank stock index used by the Corporation in the performance graph presented in the Corporation’s 2007 Financial Annual Report to Stockholders. The nature of the Corporation’s business presents challenges in identifying similar organizations for comparison purposes; however, the Corporation believes that the companies listed in the above peer group fairly represent its principal competition for executive talent and are an appropriate benchmark for comparing corporate performance.

The Compensation and Benefits Committee (as used in this section, the “Committee”) determines total compensation and each element of cash and equity compensation for all named executive officers. In determining individual compensation, the Committee relies upon the following information:

—

“Total Compensation Strategy—Committee Guidelines”—The Committee has established target pay levels for each element of cash and equity compensation (the “Committee Guidelines”). The Committee reviews and updates the Committee Guidelines periodically based on comparative competitive information. The Committee Guidelines provide base salary ranges for the Corporation’s CEO and the other named executive officers, together with annual cash incentives and equity compensation ranges expressed as a percentage of base salary. The level of total compensation and of each element of compensation reflects competitive pay levels, which approximate the median of peer group companies, as well as internal pay equity among comparable executive officer positions within the Management Group.

—

Recommendations of the Committee’s consultant—The Committee reviews peer group company information provided by Hewitt Associates, LLC (“Hewitt”), the Committee’s executive compensation consultant, including the median range for each compensation element and “total compensation” for executives at all such companies. Hewitt reviews this data with the Committee and makes recommendations regarding appropriate pay levels for the CEO and other named executives.

—

The CEO’s recommendations—The CEO makes recommendations with respect to base salary, annual cash incentive, equity compensation, and total compensation for each named executive officer other than the CEO, based on the CEO’s assessment of the named executive officer’s performance.

—

Corporate, business unit, and individual performance—The Committee reviews and evaluates overall corporate financial performance as measured against corporate-level goals for the year, as well as measures of business unit and individual performance in the context of business unit and individual performance goals established by the CEO for each business unit and each named executive officer, other than the CEO.

—

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 and 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 key factors and drawing upon the sources of information discussed above, the Committee utilizes the various elements of compensation in conjunction with each other 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 competitive factors in the marketplace for executive talent. Additionally, the Committee seeks to achieve the desired proper relative alignment of pay among its executive officers while remaining mindful of its core criteria and objectives.

The exercise of discretion by the Committee in the setting of the various elements of compensation also is an important feature of the Corporation’s compensation philosophy. The Corporation utilizes the peer group of companies listed above as an important factor in setting compensation. Specifically, the Committee’s use of peer group median compensation data in establishing guidelines and making decisions for each element of compensation ensures that the Corporation adheres to one of its core principles—competitive compensation. However, the Corporation does not rely solely on peer group comparisons because it values flexibility and discretion in adjusting around peer group levels for several reasons. The Corporation’s profile and business model are sufficiently unique that a strict adherence to peer-based financial measures and compensation practices may not sufficiently capture the particularities of the Corporation’s business or the unique challenges faced by its executive officers. The Corporation believes it is important that the Committee have sufficient flexibility to respond to (i) the Corporation’s unique circumstances; (ii) prevailing market trends; (iii) the rapidly evolving financial and regulatory environment in which the Corporation operates; and (iv) the cross-functioning of executive assignments and cross-training as a matter of executive development and succession planning. The Corporation also believes it is in the best interest of the Corporation and its stockholders that the Committee have sufficient discretion to establish performance goals and objectives recognizing and rewarding extraordinary individual performance. These may or may not immediately affect the Corporation’s achievement of specific financial metrics for a particular year relative to its peer companies, but are nevertheless important to long range growth and the enhancement of stockholder value.

The key design features of the Corporation’s executive compensation program described above have enabled the Corporation, over time, to achieve strong performance and to maintain executive leadership through identification, development, and promotion of talent from within its officer population, as evidenced by the fact that the named executive officers in this proxy statement have been employed by the Corporation for an average of 23 years. In turn, the Corporation’s historical success in retaining its executive leadership has influenced the nature and scope of the Corporation’s executive compensation program with respect to its use of stock options and performance stock units.

PRINCIPAL ELEMENTS OF THE CORPORATION’S EXECUTIVE COMPENSATION PROGRAM

Cash Compensation

The Corporation 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 an executive officer’s position and responsibilities, competitive pay practices, and internal equity of pay among the executive officers. Target base salary levels of the Corporation’s executive officers included in the Committee Guidelines described above are set at approximately the median of salaries for similar positions in the peer group companies used for comparison purposes, adjusted in the judgment of the Committee to reflect proper positioning of the salary targets for comparable roles within the Management Group. Determination of an executive’s actual base salary and the amount of annual increase is based upon the experience and qualifications of the individual executive, the executive’s tenure in the position or a position of similar level, and individual performance. 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. In 2007, the base salary for Mr. Osborn, who served as Chairman and Chief Executive Officer (“CEO”) of the Corporation until January 1, 2008 and continues to serve as Chairman, was increased by $50,000. The base salary for Mr. Waddell was increased by $75,000. The base salaries of Messrs. Fradkin, Morrison and Theriault were each increased by $25,000, the base salary of Ms. Barrat was increased by $50,000, and the base salary of Ms. Schreuder was increased by $75,000.

At its February 2008 meeting, the Committee approved the following new base salaries, effective April 1, 2008, for the following named executive officers: Mr. Waddell, who became CEO on January 1, 2008: $900,000; Mr. Fradkin: $550,000; and Ms. Schreuder: $550,000. The base salaries of the remaining named executive officers effective as of April 1, 2007 remained unchanged.

Discussion and Analysis. Annual base salary reflects the level of base cash compensation appropriate for the position based upon the Committee Guidelines. Adjustments to base salary take into account the current salary level compared to the target base salary for the position, significant changes in assignment or scope of responsibility, individual performance and contributions over the prior year relative to established goals and expectations for the position, and internal pay equity.

The Committee does not use performance targets or performance formulas to set the base salaries of the Corporation’s named executive officers. Instead, it exercises its discretion, taking into account the median of salaries for similar positions in its peer group companies and the objective and subjective factors that it believes are relevant to a particular position and to the particular individual. For example, the base salary of the CEO in a given year may be influenced by the Committee’s

assessment of the CEO’s performance in the areas of executive leadership, the development of senior officers, and progress made by the Corporation on diversity and ethics initiatives. The adjustment to a business unit leader’s base salary is likely to be affected by the performance of that business unit in the most recent fiscal year as well as the executive’s achievement of objective goals (e.g., decrease in staff turnover or revenue growth) and subjective goals (e.g., improvements in the effectiveness of communications with employees or customer satisfaction measures) established by the CEO for that executive.

The increases in base salaries of the named executive officers for 2007 were consistent with the Corporation’s compensation philosophy and the particular objectives the base salary element is intended to recognize. They also were consistent with the Corporation’s overarching criteria that each element of compensation should be both competitive and performance based. Specifically:

—

Mr. Osborn’s 2007 base salary adjustment reflects the Committee’s evaluation of Mr. Osborn’s performance in 2007 as well as his long tenure in the position of Chairman, CEO, and as a member of the Management Group of the Corporation. Mr. Osborn’s base salary is positioned slightly above the target base salary level in the Committee Guidelines, based on the additional factors described below under “CEO Compensation.”

—

Mr. Waddell’s 2007 base salary adjustment reflects his promotion to President and Chief Operating Officer in February 2006 and subsequent movement toward the target base salary level set forth in the Committee Guidelines. This increased salary is slightly below the current target pay level, primarily reflecting Mr. Waddell’s short tenure in the position.

—

Ms. Schreuder’s 2007 base salary adjustment reflects her promotion to President – Worldwide Operations and Technology in October 2006 and subsequent movement toward the target base salary level set forth in the Committee Guidelines. This increased salary is slightly below the current target pay level, primarily reflecting Ms. Schreuder’s short tenure in the position.

—

The 2007 increases for the other named executive officers were in accordance with the Corporation’s salary policy to enhance internal pay equity, reflect their individual performance and align their base salaries at approximately the median level of their counterparts at the Corporation’s peer group companies. Base salaries for the remaining named executive officers are at or slightly below the target base salary level set forth in the Committee Guidelines.

Annual Cash Incentives

The Corporation provides annual cash incentives as performance based compensation to reward successful achievement of financial and operating objectives for the most recent fiscal year.

The Committee determines and approves annual cash incentives for the Corporation’s executive officers under the provisions of the stockholder-approved Management Performance Plan (the “MPP”). Awards under the MPP qualify as performance based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”) because they are tied to the Corporation’s net income results for the prior year and may not exceed the following maximum award limitations 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 $4.4 million for 2007); (ii) the award for the President, any Vice Chairman, the Chief Operating Officer (“COO”), or a combined President and COO position may not exceed 0.4% of consolidated net income (or approximately $2.9 million for 2007); and (iii) the award for each of the other MPP participants may not exceed 0.3% of consolidated net income (or approximately $2.2 million for 2007). Each year, the Committee sets a guideline reference range of opportunity with respect to annual cash incentives for each named executive officer as a percentage of base salary ranging from 0% to 300%. The guideline reference range is established to approximate the median of annual cash incentives of the Corporation’s peers, based upon review of cash bonus information of the peer group companies referenced above, as further adjusted for additional factors such as the officer’s position, responsibilities and performance and subject to the MPP award limitations described above.

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. For 2007, the annual cash incentive guideline reference ranges set forth in the Committee Guidelines referred to above were 0 to 3 times base salary for the Chairman and CEO, 0 to 2.5 times base salary for the President and COO, and 0 to 2 times base salary for the other named executive officers. Actual awards made to the named executive officers for 2007, which are shown in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table presented elsewhere in this proxy statement, were within the peer-based guideline reference range and below the maximum levels permitted.

Discussion and Analysis. Annual cash incentive awards are designed principally to recognize an executive officer’s performance over the prior year, while remaining competitive with the Corporation’s peers. The guideline reference ranges upon which the actual MPP awards are based are not performance targets. Rather, they reflect the Committee’s consideration of the nature and scope of the named executive officers’ job responsibilities, relevant peer group company information with respect to cash bonuses, and the award limitations under the MPP set forth above. As is the case with base salaries, annual cash incentives actually awarded to the named executive officers are not tied to any specific formula. Rather, the Committee exercises its discretion to grant annual cash incentives based on an overall assessment of how individual executive officers and the Corporation itself performed in the prior fiscal year.

In determining annual cash incentive awards for the CEO and other named executive officers, the Committee considers several key corporate performance measures compared to the established performance goals for the year.

The reported results for 2007 were significantly impacted by $150 million of pre-tax charges related to certain indemnifications that the Bank, as a member bank of Visa U.S.A., Inc. and in conjunction with other member banks, provides to Visa, Inc. (“Visa”), which reduced net income by $94.2 million, or $.42 per diluted common share. Although the ultimate resolution of the Visa litigation matters is highly uncertain, the Corporation expects that its proportionate share of the proceeds of

Visa’s planned initial public offering will more than offset any indemnification liabilities related to the litigation. As such, the Committee has concluded that operating earnings, a financial measure not in accordance with generally accepted accounting principles in that it excludes the impacts of the Visa indemnification charges, provides a clearer indication of the results and trends in the Corporation’s core businesses and are a more appropriate measure upon which to base its compensation decisions.

The 2007 annual cash incentives for the CEO and other named executive officers reflected the following results (exclusive of the aforementioned Visa indemnification charges) compared to the Corporation’s long-term financial targets, as most recently revised in May 2006:


Performance Measure	Annual Target	Actual 2007 Results
Earnings Growth per Share	10% to 12%	22%*
Revenue Growth	8% to 10%	17%
Return on Common Equity	16% to 18%	19.7%*
Operating Leverage	Positive	Positive

* Based on Operating Earnings

Actual MPP awards for 2007 reflected the Committee’s review and consideration of the following factors:

—

The Corporation’s performance for 2007 as noted above;

—

The financial and operating results of the applicable business unit including, as appropriate, revenue growth, growth in client assets, international growth, net income, and expense management;

—

The named executive officer’s success in achieving individual goals and objectives including, as appropriate, leadership, client service, communication, ethics, diversity, and the development of senior officers; and

—

The recommendations of the CEO with respect to each named executive officer other than himself.

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 2008, subject to any revisions in the Corporation’s long-term financial targets.

The above factors are the types of factors generally considered by the Committee in determining annual incentive awards, but performance in different years may be assessed by different criteria as determined by the Committee. For example, for 2007, the Committee granted (i) an annual cash incentive to the CEO equal to approximately 3.9 times his base salary, and annual cash incentives of approximately 1.3 times base salary for the other named executive officers, based on the performance measures and other factors referenced above. By contrast, the Committee has the discretion, which it has exercised in the past, not to make any annual cash incentive awards to the named executive officers on the basis that the Corporation’s performance in a particular year did not merit such awards, notwithstanding the positive individual accomplishments of the named executive officers.

Equity Compensation

The Corporation uses equity compensation to provide longer-term incentives for its named executive officers and other executives. The use of equity compensation serves to align the interests of the named executive officers and other executives with those of the Corporation’s stockholders. Long-term, equity-based compensation is the most significant component of overall compensation. The Corporation believes that using meaningful time periods for vesting, along with stock ownership and retention guidelines, contributes to continuity and stability within the Corporation’s executive leadership.

Forms of Equity Compensation Utilized. Equity compensation typically takes the form of stock options and performance stock units (which convert into shares of common stock on a one-for-one basis, subject to the achievement of designated performance goals). In the past, the Corporation also has granted, and on occasion may grant in the future, restricted stock units (which also convert into shares of common stock on a one-for-one basis, subject to satisfaction of a vesting period). The Amended and Restated Northern Trust Corporation 2002 Stock Plan, which was approved by stockholders at the 2007 annual meeting, also provides for the issuance of other types of equity-based awards, including stock awards, stock appreciation rights, and performance shares.

Stock Options. Stock options are granted with an exercise price equal to the market 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.

Stock options vest over a specified vesting period determined by the Committee. If the executive dies or becomes disabled, the 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.

Performance Stock Units. 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. If 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 a distribution of a prorated number of performance stock units at the completion of the performance 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.

Restricted Stock Units. Restricted stock unit awards were made to executive officers in 2006, but none were made to executive officers in 2007 or 2008. Each restricted stock unit entitles an executive to receive one share of stock in the year in which the award vests. Restricted stock units vest over a specified vesting period determined by the Committee. The restricted stock units granted in 2006 vest at a rate equal to 50% on the third anniversary of the date of grant and 50% on the fourth anniversary of the date of grant. The 2006 restricted stock units otherwise mirror the performance stock units in terms of the payment of dividend equivalents and pro-rata vesting upon death, disability, retirement or termination of employment as described in the preceding paragraph, 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.

Equity Compensation Determinations. For 2007, under the Committee Guidelines referred to above, the guideline range for the total dollar amount of equity compensation was approximately seven-to-eight times base salary for the Chairman and CEO, approximately four-to-five times base salary for the President and COO, and approximately three-to-four times base salary for the other named executive officers. Based on the Committee Guidelines, the Corporation fixed the actual total dollar amount of equity compensation for each named executive officer in 2007 in connection with a corporate-wide review and evaluation of the Corporation’s executive talent.

Stock Options. The 2007 stock options vest in equal installments over a four-year vesting period ending in 2011. Stock option grants made in 2007 to the named executive officers are shown in the Grants of Plan-Based Awards table presented elsewhere in this proxy statement.

At its February 2008 meeting, the Committee granted the following number of stock options, with a four-year vesting period ending in 2011, to the named executive officers: Mr. Osborn: 126,532; Mr. Fradkin: 42,118; Mr. Waddell: 126,352; Mr. Morrison: 42,118; Mr. Theriault: 42,118; Ms. Barrat: 42,118; and Ms. Schreuder: 42,118.

Performance Stock Units. Performance stock unit awards made in 2007 to the named executive officers are shown in the Grants of Plan-Based Awards table presented elsewhere in this proxy statement. The 2007 performance stock units vest subject to the satisfaction of a performance goal based on the Corporation’s average annual earnings per share growth over the three-year period ending December 31, 2009, as more specifically described in the footnote to the “Stock Awards” column of the Summary Compensation Table presented elsewhere in this proxy statement.

At its February 2008 meeting, the Committee granted the following number of performance stock units, with vesting subject to satisfaction of a performance goal based on the Corporation’s average annual earnings per share growth over the three-year period ending December 31, 2010, to the named executive officers: Mr. Fradkin: 14,040; Mr. Waddell: 42,118; Mr. Morrison: 14,040; Mr. Theriault: 14,040; Ms. Barrat: 14,040; and Ms. Schreuder: 14,040.

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 positions at the Corporation’s peer group 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 specific forms of equity compensation utilized by the Corporation are performance based. The Corporation views stock options as inherently performance based in that the award will not provide any financial benefit to an executive unless the stock price increases following the grant of the award. Additionally, performance stock units attain value only to the extent that the associated performance goals are satisfied.

The Committee first determines the total dollar amount of equity compensation that it seeks to provide in a given year to each named executive officer. The Committee develops a guideline range for the total dollar amount of equity compensation for each executive officer that approximates the median level of equity compensation for similar positions at peer group companies. The Committee sets the actual amount of total equity compensation for each executive as an adjustment against this peer-group based guideline. Those adjustments are based on its discretionary assessment of the named executive officer’s performance, the CEO’s recommendation, and equity awards granted in the prior two 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.

Once the total equity compensation amount for each executive officer is established as an adjustment against the peer-based guideline, the Committee then allocates that dollar amount among stock options and performance stock units based on the fair market value of the awards at the date of grant. The fair market value of the stock options is determined using a methodology substantially similar to the Black-Scholes methodology. The values of performance stock unit awards are discounted from their values as calculated under the Statement of Financial Accounting Standard No. 123(R) (“SFAS No. 123(R)”) to reflect risks of forfeiture (non-vesting) of these awards due to the potential of not satisfying the required service or performance requirements under these awards. The valuation of the Corporation’s equity compensation is consistent with the valuation of the equity awards of the Corporation’s peer group companies considered by the Corporation in determining the total dollar amount of equity compensation to be provided to the named executive officers.

Based on the 2007 equity compensation guidelines, the Committee fixed the actual total dollar amount of equity compensation for each named executive officer in 2007 in connection with a corporate-wide review and evaluation of the Corporation’s executive talent that considered the following factors:

—

An assessment of the named executive officer’s individual performance, level of contribution to the overall long-term success of the Corporation, impact of individual performance on the financial results of the Corporation, and demonstrated leadership;

—

The recommendations of the CEO with respect to each named executive officer other than himself; and

—

The value of equity compensation awarded to the named executive officer in the prior two years.

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 was the case in 2007, the CEO’s recommendation is a very significant factor in the setting of equity compensation for named executive officers other than the CEO.

In 2007, the Corporation allocated the equity compensation of its named executive officers in the following manner:

—

Stock options—approximately 50% of the total value of equity compensation; and

—

Performance stock units—approximately 50% of the total value of equity compensation.

This allocation reflects a greater use in 2007, as compared to prior years, of performance based awards, particularly performance stock units, in lieu of restricted stock units where vesting is tied exclusively to continued employment. Historically, the Corporation utilized an equity compensation mix of 60% allocated to stock options, 20% allocated to performance stock units, and 20% allocated to restricted stock units. However, in recent years, the Corporation has increased its use of performance based awards by providing only performance stock units and non-qualified stock options for the following reasons: (i) performance stock units provide a means of rewarding objective financial goals over time while delivering payment in the form of equity, thus linking the reward to stockholder interests; (ii) SFAS No. 123(R) eliminated undesirable accounting treatment for performance stock units; (iii) stock options provide an additional performance based reward linked to the Corporation’s long-term stock price performance; (iv) the use of performance stock units and allocation of performance stock units and stock options reflects current trends and the practices of the Corporation’s peer group companies; and (v) exclusive use of stock options and performance stock units allows the Corporation to distinguish between incentives based on continued employment and those based on performance.

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 100% of the first 3% of deferred salary and 50% of the next 3% of deferred salary, for a maximum matching contribution of 4.5% of salary. In addition, for each year in which the Corporation attains an annual earnings goal, the executives receive a profit sharing contribution equal to 1% of base salary, up to the annual Code compensation limit.

Under Supplemental TIP, named executive officers can contribute a portion of their base salary that exceeds the annual Code compensation limit ($225,000 in 2007). The Corporation makes a matching contribution under Supplemental TIP using the formula in TIP. The Corporation makes no profit sharing contribution to Supplemental TIP unless other applicable Code limits would prevent the full profit sharing contribution from being made to TIP. The named executive officers are fully vested in their retirement benefits under TIP and Supplemental TIP.

2007 Retirement Benefits. The aggregate change during 2007 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 and profit sharing 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.

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 and profit sharing contributions from the employer, under TIP and Supplemental TIP. The design of the Corporation’s retirement program for employees, including the named executive officers, reflects the following considerations:

—

Competitiveness: The Corporation targets aggregate retirement benefits at approximately the median level of certain peer group companies, including those identified above.

Retirement benefits are designed with respect to employees as a group and thus are not specifically structured for the named executive officers.

—

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.

ADDITIONAL ELEMENTS OF COMPENSATION

Perquisites and Other Benefits

2007 Perquisites and Other Benefits. The Corporation provided the following perquisites to its executive officers in 2007:

—

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

—

Housing assistance in limited cases where an executive officer relocates for business reasons.

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 that is considered a taxable benefit to the named executive officer. The named executive officers also participate in the employer’s medical, retiree medical, dental and life insurance programs on the same terms as other employees.

Disclosure of the dollar value of each perquisite provided to the named executive officers in 2006 and 2007 is set forth in the table set forth in footnote 6 to the Summary Compensation Table presented elsewhere in this proxy statement.

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 central to the Corporation’s executive compensation philosophy. The Corporation’s perquisites are limited in number and modest in dollar value in comparison to its principal elements of compensation. They are intended to assist executive officers in the performance of their duties on behalf of the Corporation, to help them manage some forms of compensation to realize their intended value, or otherwise to provide benefits that have a combined personal and business purpose. The Committee annually reviews the types and costs of perquisites provided by the Corporation to its executive officers to be sure that the perquisites are in line with this philosophy.

Change in Control Benefits

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. On February 20, 2007, the Corporation and Mr. Osborn, Chairman and former CEO of the Corporation, terminated, at his request, his employment security agreement. Accordingly, the following description applies to the employment security agreements in place with each named executive officer other than Mr. Osborn.

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, 2007, 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 occur and second, within two years following the change in control, the executive must voluntarily 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 defined in the employment security agreements to include the acquisition of 20% or more of the Corporation’s common stock, certain mergers, consolidation 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 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 motivated to act contrary to the best interests of the Corporation and its stockholders prior to, during, or after a change in control. The Corporation 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;

—

The protection afforded by the employment security agreements provides appropriate motivation for the Corporation’s executives when considering whether any change in control is in the best interests of the Corporation; and

—

Change in control protection for executives is prevalent in the competitive environment in which the Corporation operates.

Severance Benefits

The Corporation maintains a severance plan for eligible employees, including the named executive officers.

Description of Severance Benefits. The named executive officers 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 benefits may not exceed two times the annual Code compensation limit for retirement plans ($225,000 in 2007). The named executive officers also would be entitled to 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 FACTORS RELEVANT TO THE DETERMINATION OF EXECUTIVE COMPENSATION

Timing of Equity Compensation Awards

The Committee currently 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 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. The delegated authority was not exercised in 2007.

Stock Ownership Target Guidelines

Stock ownership and stock retention levels are among the factors in the setting of executive compensation for the named executive officers and other executives. Effective January 1, 2006, the Corporation implemented stock ownership target guidelines for the Corporation’s executive officers and directors. The guidelines identify a target number of shares of common stock that the executive officers and directors are expected to accumulate and hold within five years. The specific stock ownership target guidelines are based on the lesser of (i) a multiple of base salary ranging from two-to-five times and (ii) a fixed number of shares, depending upon the executive officer’s position and responsibilities.

The target guideline applicable to the CEO is the lesser of the number of shares having a value equal to five times base salary or 125,000 shares. For the other named executive officers, the target guideline ranges from the lesser of the number of shares having a value equal to three-to-four times base salary or 37,500 to 75,000 shares. For directors, the target guideline is the lesser of the number of shares having a value equal to five times the annual cash retainer or 10,000 shares, of which 1,000 shares are expected to be owned within the first year of joining the board and the remainder are expected to be owned within five years of joining the board. In all cases, 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, vested stock units and 50% of unvested restricted stock units and stock awards. In addition, there is an expectation that the executive officers and directors will retain 75% of the net shares received from stock awards and stock options, after deductions for taxes and option exercise costs, regardless of whether the stock ownership target guideline has been met.

Each named executive officer and director currently meets or exceeds the stock ownership target guidelines.

CEO Compensation

The Committee considered various additional factors in determining the appropriateness of the relative level of compensation paid to Mr. Osborn as CEO in 2007 in comparison to the compensation paid to the other named executive officers, including the following:

As CEO in 2007, Mr. Osborn was ultimately responsible for the performance of the Corporation. He answered to the directors, stockholders, clients, and employees of the Corporation, and to the regulatory authorities. Mr. Osborn’s responsibilities were wide-ranging and included his stewardship of the Corporation, the development of short-term and long-term strategic plans, goals and objectives, the development of an effective senior management team, the positioning of the Corporation for current and future success, and effective communications with all of the Corporation’s constituencies. Accordingly, in 2007, the Committee structured a compensation package for Mr. Osborn in line with the nature and scope of his job responsibilities and his accountability to the Corporation’s various constituencies.

—

A hallmark of the Corporation’s executive compensation program, as described above, is that executive compensation should be competitive. As applied to Mr. Osborn in 2007, this meant that the Committee sought to compensate him at a level competitive with CEOs of the financial services companies in its peer group, based in part on competitive data received annually from Hewitt and adjusted as necessary in the Committee’s view to reflect, among other things, the relative financial and operating performance of the Corporation and its peer group companies.

—

Under Mr. Osborn’s leadership, the Corporation has grown into a global provider of investment management, asset and fund administration, and fiduciary and banking services, with revenues for the year ended December 31, 2007 on a taxable-equivalent basis of over $3 billion.

—

Mr. Osborn is a senior banking executive who has spent his entire 37-year career at the Corporation, serving as Chairman (12 years), CEO (12 years), a Director (13 years), and a member of the Management Group (17 years).

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 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:

—

Base salaries;

—

Annual cash incentives;

—

Deferred annual cash incentives, together with the interest paid thereon;

—

Equity awards, including awards of stock options, restricted stock units, restricted stock and performance shares;

—

Retirement benefits;

—

Employment security benefits under certain situations associated with a change in control of the Corporation;

—

Health and welfare benefits (medical, dental, disability, and life insurance programs); and

—

Perquisites and other benefits.

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 Hewitt,” the Committee has retained Hewitt as its human resources consulting firm to advise the Committee on matters pertaining to executive compensation.

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 relevant historical and current market data, including data received from Hewitt, the human resources consulting firm retained by the Committee in connection with matters pertaining to executive compensation, regarding peer group compensation practices and industry trends. 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, including in particular the meeting of the Committee at which the information collected by the Human Resources Department and the Hewitt information are presented.

With respect to the compensation of the Chairman (if the Chairman is an employee of the Corporation), the Human Resources Department provides historical and current data concerning the compensation of the Chairman. Such information is presented to the Committee in the context of historical and current market data provided by Hewitt concerning the compensation of chairmen of the peer group companies listed on pages 20 and 21 of this proxy statement. 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 based on its evaluation of their respective performance against the Corporation’s goals and objectives. The Head of Human Resources and Administration participates in the discussions of the Committee concerning the setting of the compensation of the Chairman and provides such guidance in those discussions as requested by the Committee.

With respect to the compensation of the CEO, the Human Resources Department provides historical and current data concerning the compensation of the CEO. Such information is presented to the Committee in the context of historical and current market data provided by Hewitt concerning the compensation of CEOs of the peer group companies listed on pages 20 and 21 of this proxy statement. 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 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. The Head of Human Resources and Administration participates in the discussions of the Committee concerning the setting of the compensation of the CEO and provides such guidance in those discussions as requested by the Committee.

With respect to the compensation of all other executive officers other than the CEO, the Human Resources Department assists the 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 CEO is establishing recommendations. This includes information comparing such executive officers’ stock ownership measured against stock ownership guidelines approved by the Committee. Once the 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 37 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 37 of this proxy statement.

Role of the 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 CEO with assistance from the Corporation’s Human Resources Department.

The 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. In establishing such recommendations, the CEO evaluates the performance of executive officers during the prior year against performance expectations established by the 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, client development or diversity goals. In formulating his

recommendations, the CEO is assisted by the Human Resources Department which supplies data regarding historical and current compensation, as well as comparative data supplied by Hewitt, for each executive officer.

The recommendations of the 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 direct comparison of the recommendations against the historical and current comparative data supplied by the Human Resources Department and Hewitt. The recommendations and this comparative data are reviewed and evaluated by the Committee in the context of additional information on broader industry compensation trends and market practices as reported by Hewitt. The Committee gives substantial weight to the recommendations of the 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 CEO.

Role of Hewitt. The Committee has retained Hewitt as its human resources consulting firm to advise the Committee on matters pertaining to executive compensation. 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, pay philosophy, prevailing market practices, and relevant legal and regulatory mandates.

—

Provide market data as background against which the Committee can consider 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.

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 connection with the Committee’s review and approval of the compensation of the Corporation’s CEO and other executive officers, Hewitt was asked to provide comparative data and other information on current compensation practices and trends for chief executive officers and other senior executive officers in the financial services industry. At the request of the Committee, Hewitt provided information to the Committee on compensation paid by the peer group companies identified on pages 20 and 21 of this proxy statement to chief executive officers and other executive officer positions comparable to the Corporation’s executive officer positions. The purpose of this information was to provide the Committee with comparative information against which to evaluate the competitiveness of the proposed CEO compensation being reviewed and evaluated by the Committee as well as the competitiveness of executive officer compensation recommended to the Committee by the CEO. The report reviewed the total compensation paid to executives at companies in the peer group during the previous year and how the compensation of similar positions at the Corporation compared to the median of those comparative compensation figures. This comparative data was also utilized by the Human Resources Department in the production of materials distributed to the Committee in advance of its meeting (including the summary sheets referenced on page 37 of this proxy statement).

Representatives of Hewitt attended all meetings of the Committee at which compensation was reviewed and approved, presented Hewitt’s comparative compensation data (as well as 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 responded to specific questions of Committee members.

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. The Corporation also provides in its restricted stock unit agreements under the Amended and Restated 2002 Stock Plan that the payment of the stock units is mandatorily deferred to the first year in which it would result in tax deductible compensation. As a result, in 2007, substantially all compensation paid to the CEO, and all compensation paid to the other named executive officers, was fully tax deductible.

SUMMARY COMPENSATION TABLE

The following table sets forth compensation information for the Corporation’s CEO, chief financial officer, and the five other most highly compensated executive officers for the year ended December 31, 2006 and the year ended December 31, 2007. William A. Osborn served as Chairman and CEO of the Corporation through December 31, 2007. Effective January 1, 2008, Mr. Osborn resigned from the position of CEO, but continues to serve as Chairman of the Corporation, with responsibilities that include representation of the Corporation with clients and consultation on significant strategic matters, in addition to his continuing role with the Corporation’s board of directors. Frederick H. Waddell, who served as President and Chief Operating Officer through December 31, 2007, assumed the position of CEO on January 1, 2008 and now serves as President and CEO of the Corporation.

(1) Salary. Salary adjustments for each named executive officer during 2006 were effective April 1, 2006, except that Ms. Barrat’s salary adjustment became effective on January 1, 2006. Salary adjustments for each named executive officer during 2007 were effective April 1, 2007.

(2) Stock Awards. This column shows the dollar amount recognized by the Corporation for financial statement reporting purposes in 2006 and 2007 in accordance with SFAS No. 123(R) for all outstanding restricted stock units and performance stock units granted to each named executive officer. See footnote 23 to the Consolidated Financial Statements contained in the Corporation’s 2007 Financial 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.

The total value of the restricted stock units and performance stock units reported in the “Stock Awards” column is different from the total grant date fair value of the restricted stock unit and performance stock unit awards granted in the applicable year because the “Stock Awards” column includes, as required by SFAS No. 123 (R), the expense of awards granted in prior years where the vesting period for those awards extends into the year presented. The grant date fair value for restricted stock units and performance stock units granted in 2006 and 2007 to the named executive officers was as follows:



	Grant Date Fair Value

Name	2006 Restricted Stock Units	2006 Performance Stock Units	2006 Total Stock Units	2007 Performance Stock Units
William A. Osborn	$1,611,142	$1,611,142	$3,222,284	$5,500,028
Steven L. Fradkin	$ 333,356	$ 333,356	$ 666,712	$1,133,384
Frederick H. Waddell	$1,802,225	$ 444,475	$2,246,700	$1,833,385
William L. Morrison	$ 366,697	$ 366,697	$ 733,394	$1,133,384
Timothy J. Theriault	$ 366,697	$ 366,697	$ 733,394	$1,133,384
Sherry S. Barrat	$ 333,356	$ 333,356	$ 666,712	$1,133,384
Jana R. Schreuder	$ 244,482	$ 244,482	$ 488,964	$1,000,011

The “Compensation Discussion and Analysis—Principal Elements of the Corporation’s Executive Compensation Program—Equity Compensation—Forms of Equity Compensation Utilized—Restricted Stock Units;—Performance Stock Units” sections of this proxy statement contain vesting and other additional information about the restricted stock unit awards made in 2006 and the performance stock unit awards made in 2006 and 2007.

Dividend equivalents on restricted stock units and performance stock units held or deferred by a named executive officer are paid on a current basis. Dividend equivalents paid on restricted stock units and performance stock units for each named executive officer for 2006 were: Mr. Osborn: $364,598; Mr. Fradkin: $42,411; Mr. Waddell: $60,764; Mr. Morrison: $56,634; Mr. Theriault: $54,794; Ms. Barrat: $33,671; and Ms. Schreuder: $29,476. Dividend equivalents paid on performance stock units for each named executive officer for 2007 were: Mr. Osborn: $476,209; Mr. Fradkin: $56,714; Mr. Waddell: $105,520; Mr. Morrison: $71,500; Mr. Theriault: $69,500; Ms. Barrat: $47,968; and Ms. Schreuder: $41,223.

(3) Option Awards. This column shows the dollar amount recognized by the Corporation for financial reporting purposes in 2006 and 2007 in accordance with SFAS No. 123(R) for all outstanding stock options granted to each named executive officer. See footnote 23 to the Consolidated Financial Statements contained in the Corporation’s 2007 Financial Annual Report to Stockholders for a discussion of the assumptions made by the Corporation in the valuation of these option awards, including that dividend equivalent payments are factored into the option valuation.

Under SFAS No. 123(R), the fair value of option awards is recognized as expense over the vesting period of the award except where it is accelerated for employees who, under the award agreements, are retirement-eligible or will become retirement-eligible during the vesting period. The value of the stock options reported in the “Option Awards” column is different from the grant date fair value of the stock options granted in the applicable year for the following reasons: (i) the “Option Awards” column

includes, as required by SFAS No. 123(R), the expense of awards granted in prior years where the vesting period for those awards extends into the year presented to the extent the expense was not previously accelerated due to retirement-eligibility of the employees and (ii) the “Option Awards” column for 2006 and 2007 option awards includes the full or accelerated expense for those employees that were retirement-eligible prior to the year presented (Mr. Osborn and Ms. Barrat), were deemed retirement-eligible as of the applicable year (Mr. Morrison), or will become retirement-eligible during the vesting period of the applicable option awards (Mr. Waddell). In contrast, the expense of the option awards for non-retirement-eligible employees (Mr. Fradkin, Mr. Theriault, and Ms. Schreuder) is spread equally over the full vesting period. The grant date fair value for stock options granted in 2006 and 2007 to the named executive officers was as follows:



Name	Grant Date Fair Value of Stock Options
	2006	2007
William A. Osborn	$4,266,274	$3,392,057
Steven L. Fradkin	$ 882,683	$ 698,981
Frederick H. Waddell	$1,176,906	$1,130,697
William L. Morrison	$ 970,950	$ 698,981
Timothy J. Theriault	$ 970,950	$ 698,981
Sherry S. Barrat	$ 882,683	$ 698,981
Jana R. Schreuder	$ 647,305	$ 616,747

The “Compensation Discussion and Analysis—Principal Elements of the Corporation’s Executive Compensation Program—Equity Compensation—Forms of Equity Compensation Utilized—Stock Options” section of this proxy statement contains vesting and other additional information about the stock option awards made in 2006 and 2007.

(4) Non-Equity Incentive Plan Compensation. This column shows the annual cash incentives earned by the named executive officers in 2006 and 2007 under the MPP. As described in the “Compensation Discussion and Analysis—Principal Elements of the Corporation’s Executive Compensation Program—Cash Compensation—Annual Cash Incentives” section of this proxy statement, these annual cash incentives are fully deductible as performance based compensation under Section 162(m) of the Code.

(5) Change in Pension Value and Nonqualified Deferred Compensation Earnings. This column shows the increase from September 30, 2005 to September 30, 2006 (the measurement date used for reporting purposes in the Corporation’s 2006 Financial Annual Report to Stockholders) and the increase from September 30, 2006 to September 30, 2007 (the measurement date used for reporting purposes in the Corporation’s 2007 Financial Annual Report to Stockholders) in the actuarial present value of accumulated benefits for each named executive officer under the Pension Plan and the Supplemental Pension Plan. It does not include any above-market or preferential earnings on deferred compensation as the Corporation does not pay above-market or preferential interest on the deferred compensation of its named executive officers. Amounts shown for the period September 30, 2005 to September 30, 2006 have been restated to reflect a correction in the applicable early retirement ages used in these calculations.

(6) All Other Compensation. The table below provides a breakdown of the amounts shown in the “All Other Compensation” column for each named executive officer in 2006 and 2007.

(d) TIP/Supplemental TIP Contributions. This column reflects matching and profit sharing contributions made on behalf of the named executive officers to TIP and Supplemental TIP, both of which are defined contribution plans, as described above under “Compensation Discussion and Analysis—Principal Elements of the Corporation’s Executive Compensation Program—Retirement Benefits—Description of Principal Retirement Benefits—TIP and Supplemental TIP.”

(e) From time to time since 1998, the Corporation has made charitable contributions in support of the Noble Network of Charter Schools. In furtherance of this long-standing history of charitable support for the Noble Network and in recognition of Mr. Osborn’s years of service as CEO of the Corporation, on December 28, 2007, the Corporation made a charitable contribution to the Noble Network in the amount of $1 million in honor of Mr. Osborn. This amount is not included in the table above. The Noble Network has informed the Corporation that it intends to name one of its new schools to be opened in 2009 in honor of Mr. Osborn and his wife, Cathleen.

(1) Grant Date. In each case, the “Grant Date” reflects the date on which the Compensation and Benefits Committee acted to approve the grant of the award.

(2) Estimated Possible Payouts Under Non-Equity Incentive Plan Awards. These columns show the range of potential payouts under the MPP based on the Corporation’s performance in 2007. “Threshold” and “Target” awards under the MPP were not determinable as the MPP authorizes the Committee to award annual cash incentives ranging from $0 to the following maximum award limitations (“Maximum” awards): Chairman, the CEO or a combined Chairman and CEO position—0.6% of consolidated net income; President, any Vice Chairman, COO, or a combined President and COO—0.4% of consolidated net income; and the other named executive officers—0.3% of consolidated net income. Where “Target” awards are not determinable, the SEC rules require the disclosure of representative amounts based on the previous fiscal year’s performance. Accordingly, the Corporation

has disclosed in the “Target” column the MPP awards paid to the named executive officers for 2006. The amounts paid under the MPP for 2007 appear in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table.

(3) Estimated Future Payouts Under Equity Incentive Awards. These columns show the range of potential performance stock units that could be earned by the named executive officers based on grants made under the 2002 Stock Plan in 2007. These performance stock units vest subject to the satisfaction of a performance goal based on the Corporation’s average earnings per share growth over the three-year period ending December 31, 2009, as follows:



Average Three-Year Earnings Per Share Growth		Percentage of Stock Units Vested
12% and above		125%
11.5%		117.5%
11%		110%
10.5%		105%
10.0%		100%
9.5%		95%
9%		90%
8.5%		82.5%
8%		75%
Less than 8%		0%

As shown, average three-year earnings per share growth below 8% will result in no vesting of any stock units; average three-year earnings per share growth of 8% will result in the vesting of 75% of the stock units (“Threshold”); average three-year earnings per share growth of 10% will result in the vesting of all stock units (“Target”); and average three-year earnings per share growth of 12% or more will result in the vesting of 125% of the stock units awarded (“Maximum”).

(4) All Other Stock Awards: Number of Shares of Stock or Units. This column reflects that no restricted stock units were granted to the named executive officers in 2007.

(5) All Other Option Awards: Number of Securities Underlying Options. This column shows the number of shares that may be issued to the named executive officers upon exercise of stock options granted in 2007.

(6) Exercise Price. In 2007, the exercise price for all stock options was the closing sale price of the Corporation’s common stock on the date of grant. In each case, the exercise price was equal to or greater than the closing market price of the Corporation’s common stock on the date of grant.

(7) Grant Date Fair Value. The grant date fair value of the stock and option awards was computed in accordance with SFAS No. 123(R).

OUTSTANDING EQUITY AWARDS AT FISCAL YEAR-END

The following table sets forth information for each named executive officer with respect to:

—

Each stock option to purchase common stock that had not been exercised and remained outstanding at December 31, 2007; and

—

Each award of restricted stock units and performance stock units that had not vested and remained outstanding at December 31, 2007.

The information presented in the Pension Benefits table is as of the measurement date of September 30, 2007, which is the measurement date used for reporting purposes in the Corporation’s 2007 Financial Annual Report to Stockholders.

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: 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 Code or Pension Plan restrictions also participate in the Supplemental Pension Plan. All named executive officers participate in both Plans.

Benefit Formula: The benefits of the named executive officers are 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, overtime and certain types of performance-based incentive compensation, including Northern Performance Incentives under the Northern Partners Incentive Plan, 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 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.

Pension benefits are first calculated without regard to 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: A participant is eligible to receive a benefit under the Pension Plan and Supplemental Pension Plan after completing three years of vesting service.

Retirement: A participant is eligible for a normal retirement benefit based on the Traditional Formula 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 5^th 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. 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. Mr. Osborn

and Ms. Barrat are eligible for early retirement benefits. All other named executives have earned vested terminee benefits.

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. The assumptions used in calculating the present value of the accumulated benefit are set forth in footnote 22 to the Consolidated Financial Statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each contained in the Corporation’s 2007 Financial Annual Report to Stockholders. The Corporation does not grant extra years of credited service under the Pension Plan, other than as noted above under “Compensation Discussion and Analysis—Additional Elements of Compensation—Severance Benefits.”

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 2007 performance (net of fees) of the investment alternatives is as follows:

* Investment Alternative was available only through March 31, 2007. Return shown above is return from January 1, 2007 through March 31, 2007.

** Investment Alternative was available only after March 31, 2007. Return shown above is return from April 1, 2007 through December 31, 2007.

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 the Thrift-Incentive Plan. 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 30^th his or her base salary exceeded the Code compensation limit ($225,000 in 2007). Employees are eligible to participate in TIP and elect salary deferrals immediately upon their hire, and are eligible for employer matching contributions and profit sharing contributions after six months of service. All named executive officers participate in both Plans.

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. The Corporation makes a matching contribution under Supplemental TIP using the formula in TIP (i.e., a matching contribution equal to 100% of the first 3% of deferred salary and 50% of the next 3% of deferred salary, for a maximum matching contribution of 4.5% of salary). For each year in which the Corporation attains an annual earnings goal, it makes a profit sharing contribution to TIP equal to 1% of base salary (up to the annual Code compensation limit) to all eligible employees. However, the Corporation makes no profit sharing contribution to Supplemental TIP unless other applicable Code limits would prevent the full profit sharing contribution from being made to TIP.

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 are fully vested in their TIP and Supplemental TIP accounts.

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. The 2007 performance of the investment alternatives is as follows:

** Investment Alternative was available only after March 31, 2007. Return shown above is return from April 1, 2007 through December 31, 2007.

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 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 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 15^th day of the third month following such separation from service. “Executive Contributions 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 appreciation in the value of the deferred stock units, which is based on the appreciation 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 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 other than Mr. Osborn, the Corporation’s Chairman and former CEO. On February 20, 2007, the Corporation and Mr. Osborn terminated, at his request, his employment security agreement. Accordingly, the following description applies to the employment security agreements in place with each named executive officer other than Mr. Osborn. 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 of 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, 2007 (the last business day of 2007), would be as follows: Mr. Fradkin: $3,100,000; Mr. Waddell: $4,275,000; Mr. Morrison: $3,300,000; Mr. Theriault: $3,450,000; Ms. Barrat: $2,675,000; and Ms. Schreuder: $2,400,000.

—

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, 2007, would be as follows: Mr. Fradkin: $533,333; Mr. Waddell: $700,000; Mr. Morrison: $550,000; Mr. Theriault: $600,000; Ms. Barrat: $341,667; and Ms. Schreuder: $300,000.

—

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%) provided in the awards. The named executive officers become entitled to 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, 2007, the fully vested equity awards would have the following values for each named executive officer:


Mr. Fradkin:	$	1,932,314	(stock options)
	$	2,366,245	(restricted stock units)
	$	2,324,873	(performance stock units)

Mr. Waddell:	$	2,887,878	(stock options)
	$	5,248,180	(restricted stock units)
	$	3,586,625	(performance stock units)

Mr. Morrison:	$	2,312,617	(stock options)
	$	3,372,507	(restricted stock units)
	$	2,386,137	(performance stock units)

Mr. Theriault:	$	2,243,967	(stock options)
	$	3,142,767	(restricted stock units)
	$	2,386,137	(performance stock units)

Ms. Barrat:	$	1,829,339	(stock options)
	$	1,638,735	(restricted stock units)
	$	2,324,873	(performance stock units)

Ms. Schreuder:	$	1,416,227	(stock options)
	$	1,354,930	(restricted stock units)
		$1,960,065	(performance stock units)

—

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. Fradkin: $41,745; Mr. Waddell: $35,100; Mr. Morrison: $42,150; Mr. Theriault: $42,555; Ms. Barrat: $41,037; and Ms. Schreuder: $40,227. These amounts are derived by multiplying the Corporation’s annual cost of providing such coverage in 2007 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, 2007, the value of these age and service credits to each named executive

officer would be: Mr. Fradkin: $139,425; Mr. Waddell: $1,271,641; Mr. Morrison: $305,813; Mr. Theriault: $167,954; Ms. Barrat: $319,485; and Ms. Schreuder: $122,831. The assumptions used in calculating the present value of the age and service credits are set forth in footnote 22 to the Consolidated Financial Statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each contained in the Corporation’s 2007 Financial Annual Report to Stockholders.

—

Full vesting in benefits accrued under the Supplemental Pension Plan and Supplemental TIP. All named executive officers 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, 2007, the named executive officers would be entitled to the following gross-up payments: Mr. Fradkin: $2,942,779; Mr. Waddell: $4,700,055; Mr. Morrison: $2,004,636; Mr. Theriault: $2,977,236; Ms. Barrat: $2,059,505; and Ms. Schreuder: $2,089,514.

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 of 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/performance 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, at the completion of the performance period upon certification that the applicable performance goals have been met, performance stock units are eligible for distribution. In other instances where the executive leaves the Corporation during the vesting/performance period, the restricted stock units and performance stock units are forfeited. Upon a change in control of the Corporation, all restricted stock units become fully vested and all performance stock units become fully vested and immediately distributable based upon an assumption of maximum performance and payout level (125%) as provided in the awards.

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. 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.

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. In the case of Mr. Osborn, who does not have an employment security agreement, the value of his fully vested equity awards assuming a change in control of the Corporation occurred on December 31, 2007 would be: $9,407,092 (stock options), $10,409,290 (restricted stock units), and $11,269,991 (performance stock units). These values are based on the same closing market price of the Corporation’s common stock on December 31, 2007 of $76.58 and the other assumptions applied to valuation of equity awards under the employment security agreements.

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, 2007, 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. In the case of Mr. Osborn, the value of the fully vested stock options is the same as reported above in the context of a change in control absent an employment security agreement. 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 while a member of the Management Group at age 55 with the requisite service) on December 31, 2007, 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. Osborn:	$	7,537,487	(restricted stock units)
	$	3,794,794	(performance stock units)

Mr. Fradkin:	$	1,752,370	(restricted stock units)
	$	783,311	(performance stock units)

Mr. Waddell:	$	3,241,071	(restricted stock units)
	$	1,174,227	(performance stock units)

Mr. Morrison:	$	2,536,933	(restricted stock units)
	$	815,985	(performance stock units)

Mr. Theriault:	$	2,360,799	(restricted stock units)
	$	815,985	(performance stock units)

Ms. Barrat:	$	1,209,021	(restricted stock units)
	$	783,311	(performance stock units)

Ms. Schreuder:	$	1,006,423	(restricted stock units)
	$	642,481	(performance stock units)

The value of the fully vested stock options is based on the difference between the option exercise price and $76.58, which was the closing market price of the Corporation’s common stock on December 31, 2007. The value of the prorated restricted stock units and performance stock units is also based on the $76.58 closing market price and performance stock units are prorated based on the target number of units vesting (unlike the valuation in the change in control context, this estimated value does not assume vesting of performance stock units at the maximum performance level).

Charles A. Tribbett III	$82,500	$	75,000	—	—	—		—	$	157,500

(1) Terms of Office. Mr. Sosa was elected a director of the Corporation effective April 17, 2007, and Mr. Burnham retired as a director on that same date.

(2) Stock Awards. This column shows the dollar amount recognized by the Corporation for financial statement reporting purposes in 2007 in accordance with SFAS No. 123(R) for all restricted stock units granted to each non-employee director. See footnote 23 to the Consolidated Financial Statements contained in the Corporation’s 2007 Financial Annual Report to Stockholders for a discussion of the assumptions made by the Corporation in the valuation of these restricted stock unit awards. The grant date fair value of the stock awards for all non-employee directors (other than Mr. Chabraja) in 2007, computed in accordance with SFAS No. 123(R), was $80,000. The grant date fair value of the stock awards granted to Mr. Chabraja in 2007, computed in accordance with SFAS No. 123(R), was $97,589. As of December 31, 2007, each non-employee director held an aggregate of 1,245 unvested stock units, which, as described below, represented the stock unit awards made by the Corporation in February 2007 (in the case of all non-employee directors other than Mr. Sosa) and in April 2007 (in the case of Mr. Sosa).

(3) All Other Compensation. Perquisites paid or provided to directors in 2007 were less than the SEC’s minimum threshold for disclosure ($10,000). The Corporation made a charitable donation of $5,000 in Mr. Burnham’s name in connection with his retirement from the board on April 17, 2007.

General

Directors who are employees of the Corporation receive no additional compensation for serving on the board of directors or on any board committee.

2007 Director Compensation

Cash Compensation. In 2007, non-employee directors of the Corporation received the following cash compensation for their service on the board of directors:


Annual Retainer		$80,000
Additional Fee for the Chairman of each Board Committee (other than the Executive Committee)		$10,000
Additional Fee for Audit Committee Members (including the Chairman)		$ 5,000

All non-employee directors are also 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 $4,000 for such services in 2007.

Equity Compensation. In February 2007, each non-employee director then in office received a grant of stock units under the Corporation’s 2002 Stock Plan equal in value to $80,000, with the actual number of stock units (1,245 stock units) based on the closing sale price of the common stock on the date of the 2007 annual meeting of stockholders. Mr. Chabraja, who became a director of the Corporation effective January 1, 2007, also received a prorated grant of stock units on January 16, 2007 equal in value to $17,589, with the actual number of stock units (282 stock units) based on the closing sale price of the common stock on the date of the 2007 annual meeting of stockholders. Mr. Sosa, who became a director of the Corporation effective April 17, 2007, received a grant of stock units on April 17, 2007 equal in value to $80,000, with the actual number of stock units (1,245 stock units) based on the closing sale price of the common stock on the date of the 2007 annual meeting of stockholders. The award granted to Mr. Chabraja in January 2007 vested on the date of the 2007 annual meeting of stockholders. All of the stock units granted to directors in February 2007 and the award granted to Mr. Sosa in April 2007 will vest on the date of the 2008 annual meeting of stockholders. Stock units do not have voting rights. Dividend equivalents on the stock units are paid on a current basis prior to vesting and distribution. Each stock unit entitles a director to one share of common stock at vesting, unless a director elects to defer receipt of the shares.

2008 Director Compensation

All non-employee director compensation for 2008 will remain the same as it was in 2007.

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.

EQUITY COMPENSATION PLAN INFORMATION

The following table provides information as of December 31, 2007 with respect to the Corporation’s compensation plans (including individual compensation arrangements) under which equity securities of the Corporation are authorized for issuance:

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 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’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 the 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 the Independence Standards Board Standard No. 1 (Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees), as adopted by the Public Company Accounting Oversight Board in Rule 3600T. The disclosures described the relationships and fee arrangements between the firm and the Corporation. Consistent with Independence Standards Board Standard No. 1 and the rules and regulations of the SEC, the Audit Committee considered at a meeting held on January 14, 2008 whether the provision of non-audit services by the independent registered public accounting firm to the Corporation for the fiscal year ended December 31, 2007 is compatible with maintaining 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 (AICPA, Professional Standards, Vol. 1 AU Section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

The Audit Committee reviewed and discussed with management and the Corporation’s independent registered public accounting firm the audited financial statements of the Corporation for the year ended December 31, 2007.

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 financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2007, for filing with the SEC.

This report is submitted on behalf of the members of the Audit Committee:

Edward J. Mooney, Chairman

Linda W. Bynoe

Nicholas D. Chabraja

ITEM 2—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, 2008, 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, 2007. 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.

Fees of Independent Registered Public Accounting Firm



Description of Fees	Amount of Fees Payable to KPMG LLP for Fiscal Year 2007	Amount of Fees Payable to KPMG LLP for Fiscal Year 2006
Audit Fees(1)	$3,573,000	$3,793,900
Audit-Related Fees(2)	$1,144,841	$ 931,100
Tax Fees(3)	$ 232,058	$ 354,300
All Other Fees(4)	$ —	$ —
Additional Fees(5)	$ 242,750	$ 217,500

(1) Includes fees for professional services rendered for the audit of the Corporation’s annual financial statements for the fiscal year (including services relating to the audit of internal control over financial reporting under the Sarbanes-Oxley Act of 2002) and for reviews of the financial statements included in the Corporation’s Quarterly Reports on Form 10-Q and for other services that only an independent registered public accountant can reasonably provide.

(2) Includes fees for services that were reasonably related to performance of the audit of the annual 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 the aggregate fees for products and services other than those reported above, including other fees for compliance and employee benefits consulting.

(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 February 17, 2004, 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 April 14, 2003. 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, are compatible with maintaining 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 is compatible with maintaining 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, 2007, Audit-Related Fees: 0%, Tax Fees: 0%, and Other Fees: 0%.

The Board of Directors unanimously recommends that you vote FOR the ratification of KPMG LLP as the Corporation’s independent registered public accounting firm for the fiscal year ending December 31, 2008.

OTHER BUSINESS

The board of directors knows of no business to be presented at the 2008 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 90 days and not more than 120 days before the month and day that the Corporation held 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 by-laws.

STOCKHOLDER PROPOSALS FOR 2009 ANNUAL MEETING

Any stockholder proposals for the 2009 annual meeting must be received by the Corporation, directed to the attention of the Corporation’s Corporate Secretary, no later than November 10, 2008 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 by-laws of the Corporation.

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 earlier than December 16, 2008 and not later than January 15, 2009. The notice must contain the information required by the by-laws.
