Notes to Consolidated Financial Statements

1. Basis of Presentation - The consolidated financial statements include the accounts of Northern Trust Corporation (Corporation) and its subsidiaries (collectively, Northern Trust), all of which are wholly-owned. Significant intercompany balances and transactions have been eliminated. The consolidated financial statements, as of March 31, 2007 and 2006, have not been audited by the Corporation’s independent registered public accounting firm. In the opinion of management, all accounting entries and adjustments, including normal recurring accruals, necessary for a fair presentation of the financial position and the results of operations for the interim periods have been made. Expenses associated with outside services purchased, previously included as a component of other operating expenses within the consolidated statement of income, are now included as a separate component of noninterest expenses due to the increased significance of this expense category. The amortization of capitalized software, also previously included as a component of other operating expenses, is now included as a component of equipment and software expense in order to better align the nature of this expense with its income statement classification. All prior period amounts have been reclassified consistent with the current period’s presentations. For a description of Northern Trust’s significant accounting policies, refer to Note 1 of the Notes to Consolidated Financial Statements in the 2006 Financial Annual Report to Shareholders.

2. Recent Accounting Pronouncements - On July 13, 2006, the Financial Accounting Standards Board (FASB) issued its Interpretation No. 48, “Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement 109” (FIN 48), which provides guidance on the measurement, recognition, and disclosure of tax positions taken or expected to be taken in a tax return. The Interpretation also provides guidance on derecognition, classification, interest and penalties, and disclosure. FIN 48 prescribes that a tax position should only be recognized if it is more likely than not that the position will be sustained upon examination by the appropriate taxing authority. A tax position that meets this threshold is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. The cumulative effect of applying the provisions of FIN 48 is to be reported as an adjustment to the beginning balance of retained earnings in the period of adoption. Adoption of FIN 48 as of January 1, 2007 did not impact Northern Trust’s consolidated financial position or results of operations.

On July 13, 2006, the FASB issued Staff Position No. FAS 13-2, “Accounting for a Change or Projected Change in the Timing of Cash Flows Relating to Income Taxes Generated by a Leveraged Lease Transaction” (FSP 13-2), which amends FASB Statement No. 13, “Accounting for Leases.” This Staff Position addresses how a change or projected change in the timing of cash flows relating to income taxes generated by a leveraged lease affects the accounting by a lessor for that lease. FSP 13-2 requires a recalculation of the rate of return and allocation of income from the inception of a leveraged lease if, during the lease term, the expected timing of the income tax cash flows generated by a leveraged lease is revised. The recalculation includes actual cash flows that occurred up to the date of the recalculation and projected cash flows thereafter. The change in the leveraged lease net investment balances as a result of the recalculation is recognized as a gain or loss in the year that the estimated cash flows change. Additionally, a lessor must apply the provisions of FIN 48 to its tax

Notes to Consolidated Financial Statements (continued)

positions when initially calculating or subsequently recalculating leveraged lease cash flows and determining the related income allocation. The cumulative effect of applying the provisions of this Staff Position is reported as an adjustment to the beginning balance of retained earnings in the period of adoption. Based on current estimates relating to the outcome of future events, adoption as of January 1, 2007 reduced Northern Trust’s stockholders’ equity by $72.3 million and is expected to reduce 2007 net income by approximately $8 million. These amounts will be recognized into income over the remaining term of the affected leveraged leases.

In September 2006, the FASB issued FASB Statement No. 157 (SFAS No. 157), “Fair Value Measurements.” SFAS No. 157 defines fair value, establishes a framework for measuring fair value, and enhances disclosures about fair value measurements required under other accounting pronouncements, but does not change existing guidance as to whether or not an instrument is carried at fair value. Disclosures required to be provided include information on the inputs used to develop fair value measurements and the effect of the measurements on earnings. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. Adoption of SFAS No. 157 as of January 1, 2008 is currently not expected to have a material impact on Northern Trust’s consolidated financial position or results of operations.

In February 2007, the FASB issued FASB Statement No. 159 (SFAS No. 159), “The Fair Value Option for Financial Assets and Financial Liabilities.” SFAS No. 159 gives entities the option, at specified election dates, to measure certain financial assets and liabilities at fair value. The election may be applied to financial assets and liabilities on an instrument by instrument basis, is irrevocable, and may only be applied to entire instruments. Unrealized gains and losses on instruments for which the fair value option has been elected will be reported in earnings at each subsequent reporting date. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. Adoption of SFAS No. 159 as of January 1, 2008 is currently not expected to have a material impact on Northern Trust’s consolidated financial position or results of operations.

3. Stock-Based Compensation Plans - The Northern Trust Corporation 2002 Stock Plan (2002 Plan), administered by the Compensation Committee of the Corporation’s Board of Directors, provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, stock awards, stock units, and performance shares. On April 17, 2007, the 2002 Plan was amended and restated, increasing the number of shares available for future grant by 18,000,000 to 22,540,618 shares.

In the first quarter of 2007, Northern Trust granted 1,368,429 stock options with a total grant-date fair value of $23.8 million, 173,928 stock unit awards with a total grant-date fair value of $11.0 million, and 393,518 performance stock units with a total grant-date fair value of $24.9 million. Included in the compensation expense recorded in the first quarter of 2007 related to stock options was $6.3 million attributable to options granted in the first quarter of 2007 to retirement-eligible employees, which were expensed in their entirety on the grant date. Compensation expense recorded in the first quarter of 2006 included $7.5 million attributable to options granted to retirement-eligible employees.

Notes to Consolidated Financial Statements (continued)

At March 31, 2007, residential real estate loans totaling $1.2 million were held for sale and carried at the lower of cost or market. Loan commitments for residential real estate loans that will be held for sale when funded are carried at fair value and had a total notional amount of $7.3 million at March 31, 2007. All other loan commitments are carried at the amount of unamortized fees with a reserve for credit loss liability recognized for any probable losses. At March 31, 2007, legally binding commitments to extend credit totaled $20.6 billion compared with $20.0 billion at December 31, 2006 and $18.4 billion at March 31, 2006.

Total Reserve for Credit Losses	$	148.8		$	139.9

The reserve for credit losses represents management’s estimate of probable inherent losses that have occurred as of the date of the financial statements. The loan and lease portfolio and other credit exposures are regularly reviewed to evaluate the adequacy of the reserve for credit losses. In determining the level of the reserve, Northern Trust evaluates the reserve necessary for specific nonperforming loans and also estimates losses inherent in other credit exposures.

The result is a reserve with the following components:

Specific Reserve. The amount of specific reserves is determined through a loan-by-loan analysis of nonperforming loans that considers expected future cash flows, the value of collateral, and other factors that may impact the borrower’s ability to pay.

Allocated Inherent Reserve. The amount of the allocated portion of the inherent loss reserve is based on loss factors assigned to Northern Trust’s credit exposures based on internal credit ratings. These loss factors are primarily based on management’s judgment of estimated credit losses inherent in the loan portfolio as well as historical charge-off experience.

Notes to Consolidated Financial Statements (continued)

Unallocated Inherent Reserve. Management determines the unallocated portion of the inherent loss reserve based on factors that cannot be associated with a specific credit or loan category. These factors include management’s subjective evaluation of local, national, and international economic and business conditions, portfolio concentration, and changes in the character and size of the loan portfolio. The unallocated portion of the inherent loss reserve reflects management’s recognition of the imprecision inherent in the process of estimating probable credit losses.

7. Goodwill and Other Intangibles - Goodwill and other intangible assets are included in other assets in the consolidated balance sheet. The following table shows the changes in the carrying amount of goodwill by business unit for the three months ended March 31, 2007.

Note: For the quarters ended March 31, 2007 and 2006, options to purchase 6,148,087 and 6,060,018 shares of the Corporation’s common stock, respectively, were not included in the computation of diluted earnings per share because the exercise prices were greater than the average market price of Northern Trust’s common stock during these periods.

10. Net Interest Income - The components of net interest income were as follows:


	Three Months Ended March 31

Notes to Consolidated Financial Statements (continued)

11. Income Taxes - Total income tax expense for the quarter was $95.6 million, an effective tax rate of 33.9%, compared with $87.4 million in the prior year, an effective rate of 34.9%. The lower effective rate in the current quarter reflects management’s decision to indefinitely reinvest the earnings of certain non-U.S. subsidiaries.

The Corporation files income tax returns in the U.S. federal, various state, and foreign jurisdictions. The Corporation is no longer subject to income tax examinations by U.S. federal, state, or local, or by non-U.S tax authorities for years before 1997. As of the date of adoption of FIN 48, discussed in Note 2, “Recent Accounting Pronouncements,” $24.4 million of unrecognized tax benefits were included in other liabilities within the consolidated balance sheet. If recognized, all of the tax benefits would increase net income, resulting in a decrease of the effective income tax rate. Management does not anticipate significant adjustments to the total amount of unrecognized tax benefits within the next twelve months. Additionally, included in other liabilities within the consolidated balance sheet were $167 million of tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of accelerated deductions would not affect the annual effective tax rate but would accelerate the payment of cash to tax authorities to an earlier period.

Northern Trust recognizes any interest and penalties related to unrecognized tax benefits in the provision for income taxes. As of the date of adoption of FIN 48, approximately $59.6 million, $39.4 million net of tax, was accrued for the potential payment of interest and penalties.

12. Pension and Other Postretirement Plans - The following tables set forth the net periodic pension cost of the U.S. and non-U.S. pension plans, the supplemental pension plan, and the other postretirement plan for the three months ended March 31, 2007 and 2006.

13. Contingent Liabilities - Standby letters of credit obligate Northern Trust to meet certain financial obligations of its clients, if, under the contractual terms of the agreement, the clients are unable to do so. These instruments are primarily issued to support public and private financial commitments, including commercial paper, bond financing, initial margin requirements on futures exchanges and similar transactions. Certain standby letters of credit have been secured with cash deposits or participated to others. Northern Trust is obligated to meet the entire financial obligation of these agreements and in certain cases is able to recover the amounts paid through recourse against cash deposits or other participants. Standby letters of credit outstanding were $2.8 billion on March 31, 2007, $2.7 billion on December 31, 2006 and $2.7 billion on March 31, 2006. Northern Trust’s liability included within the consolidated balance sheet for standby letters of credit, measured as the amount of unamortized fees on these instruments, was $13.9 million at March 31, 2007, $7.9 million at December 31, 2006, and $7.6 million at March 31, 2006.

As part of securities custody activities and at the direction of its clients, Northern Trust lends securities owned by clients to borrowers who are reviewed by the Credit Policy Credit Approval Committee. In connection with these activities, Northern Trust has issued certain indemnifications against loss resulting from the bankruptcy of the borrower of the securities. The borrowing party is required to fully collateralize securities received with cash, marketable securities, or irrevocable standby letters of credit. As securities are loaned, collateral is maintained at a minimum of 100 percent of the fair value of the securities plus accrued

Notes to Consolidated Financial Statements (continued)

interest. The collateral is revalued on a daily basis. The amount of securities loaned subject to indemnification was $193.5 billion at March 31, 2007, $156.7 billion at December 31, 2006, and $152.0 billion at March 31, 2006. Because of the requirement to fully collateralize securities borrowed, management believes that the exposure to credit loss from this activity is remote and there are no liabilities reflected within the consolidated balance sheet at March 31, 2007, December 31, 2006, or March 31, 2006 related to these indemnifications.

In the normal course of business, the Corporation and its subsidiaries are routinely defendants in or parties to a number of pending and threatened legal actions, including actions brought on behalf of various classes of claimants, regulatory matters, and challenges from tax authorities regarding the amount of taxes due. In certain of these actions and proceedings, claims for substantial monetary damages or adjustments to recorded tax liabilities are asserted. In view of the inherent difficulty of predicting the outcome of such matters, particularly actions that seek very large damages based on novel and complex damage and liability legal theories or that involve a large number of parties, the Corporation cannot state with confidence the eventual outcome of these matters or the timing of their ultimate resolution, or estimate the possible loss or range of loss associated with them; however, based on current knowledge and after consultation with legal counsel, management does not believe that judgments or settlements, if any, arising from pending or threatened legal actions, regulatory matters or challenges from tax authorities, either individually or in the aggregate, would have a material adverse effect on the consolidated financial position or liquidity of the Corporation, although they could have a material adverse effect on operating results for a particular period.

In November and December 2003, Enron Corp. as debtor-in-possession filed two lawsuits in the bankruptcy court in New York seeking to recover for its bankruptcy estate more than $1 billion paid by Enron in the fall of 2001 to buy back its commercial paper. Enron claims that the money it paid to buy back its commercial paper approximately six weeks prior to its bankruptcy filing represented “preference” payments and “constructive fraudulent transfers” that can be reversed with the money going back to Enron. Since The Northern Trust Company (Bank), a wholly-owned subsidiary of the Corporation, sold approximately $197 million of this Enron commercial paper that it held for some of its clients to a third party broker, the Bank and those clients are among scores of defendants named in these complaints. In June 2005, the bankruptcy judge denied the defendants’ motions to dismiss the complaints. Defendants filed petitions with the Federal District Court for the Southern District of New York seeking review of the bankruptcy court ruling. The Securities and Exchange Commission, the Federal Reserve Board, and the United States Treasury Department also filed briefs supporting defendants’ position urging the District Court to review the ruling. During the first quarter of 2007, the Bank reached a tentative agreement with Enron to settle the matter. The settlement has not been documented and will require bankruptcy court approval. Based on the terms of the tentative agreement, appropriate reserves have been accrued for the matter.

Notes to Consolidated Financial Statements (continued)

As part of its audit of federal tax returns filed from 1997 – 2000, the IRS challenged the Corporation’s tax position with respect to thirteen investments made in structured leasing transactions and proposed to disallow certain tax deductions and assess related interest and penalties. During the second quarter of 2005, the IRS issued a revised examination report that continued to disallow certain tax deductions and included additional proposed adjustments to income and penalty assessments. The Corporation anticipates that the IRS will continue to disallow deductions relating to these leases and possibly include other lease transactions with similar characteristics as part of its audit of tax returns filed after 2000. In October 2005, the IRS Tax Appeals Division informed the Corporation that the Criminal Investigation Division of the IRS had initiated an investigation relating to structured leasing transactions in which the Corporation had participated. The Corporation was informed in February 2007 that the IRS, without a recommendation for prosecution, referred this matter to the United States Attorney’s Office for the Northern District of Illinois for further investigation through the grand jury process. The Corporation has been advised by the government that it is not a target of the investigation. The Corporation is cooperating fully in the investigation. The Corporation does not know the full scope of the investigation and cannot predict at this time the impact of the investigation or when or on what basis the investigation will be resolved. The Corporation believes that these transactions are valid leases for U.S. tax purposes and that its tax treatment of these transactions is appropriate based on its interpretation of the tax regulations and legal precedents; a court or other judicial authority, however, could disagree. The Corporation believes it has appropriate reserves to cover its tax liabilities, including liabilities related to structured leasing transactions, and related interest and penalties. The Corporation will continue to defend its position on the tax treatment of the leases vigorously.

14. Pledged Assets - Securities and loans pledged to secure public and trust deposits, repurchase agreements, and for other purposes as required or permitted by law were $14.3 billion on March 31, 2007, $15.8 billion on December 31, 2006 and $10.7 billion on March 31, 2006. Included in the March 2007 pledged assets were securities available for sale of $1.2 billion that were pledged as collateral for agreements to repurchase securities sold transactions. The secured parties to these transactions have the right to repledge or sell these securities.

Northern Trust is permitted to repledge or sell collateral from agreements to resell securities purchased transactions. The total fair value of accepted collateral as of March 31, 2007, December 31, 2006, and March 31, 2006 was $538.8 million, $415.2 million, and $372.9 million, respectively. There was no repledged collateral at March 31, 2007, December 31, 2006, or March 31, 2006.

15. Business Units - The table on page 23, reflecting the earnings contribution of Northern Trust’s business units for the three-month periods ended March 31, 2007, is incorporated by reference.

Item 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FIRST QUARTER CONSOLIDATED RESULTS OF OPERATIONS

Overview

Net income per common share on a diluted basis for the first quarter was $.84, an increase of 14% from $.74 per share earned in last year’s first quarter. Net income increased 15% to $186.7 million, up from $163.0 million earned in the first quarter of last year. This performance produced an annualized return on average common equity (ROE) of 19.21% versus 18.22% reported for the comparable quarter last year and an annualized return on average assets (ROA) of 1.33%, unchanged from last year.

Revenues stated on a fully taxable equivalent (FTE) basis of $823.8 million were up 11% from $743.0 million in last year’s first quarter, reflecting trust, investment and other servicing fees of $488.9 million, up 10% from the first quarter of last year. Net interest income was up 10% from a year ago to $210.3 million on a FTE basis and foreign exchange trading income was up 20% to $67.2 million. Noninterest expenses totaled $525.9 million for the quarter, up 11% from $473.3 million in the year-ago quarter.

Noninterest Income

Noninterest income totaled $613.5 million for the quarter, up 11% from $552.4 million reported last year, and accounted for 74% of total taxable equivalent revenue. Trust, investment and other servicing fees were $488.9 million in the quarter, up 10% from $442.5 million in the first quarter of last year, and represented 59% of total taxable equivalent revenue. The increase resulted primarily from higher equity markets and new business. The components of noninterest income for the first quarter of 2007 and 2006 are listed in the following table:

Noninterest Income

Noninterest Income (continued)

Assets under custody totaled $3.75 trillion at March 31, 2007. This represents an increase in assets under custody of 6% from December 31, 2006 and 20% from March 31, 2006. Assets under management totaled $755.8 billion compared with $697.2 billion at December 31, 2006 and $652.8 billion at March 31, 2006. As of the current quarter-end, managed assets were invested 35% in equities, 16% in fixed-income securities, and 49% in cash and other assets.

Trust, investment and other servicing fees are generally based on the market value of assets managed, custodied, and administered, the volume of transactions, securities lending volume and spreads, and fees for other services rendered. Certain investment management fee arrangements also may provide for performance fees, which are based on client portfolio returns exceeding predetermined levels. In addition, Corporate & Institutional Services (C&IS) client relationships are generally priced to reflect earnings from activities such as foreign exchange trading and custody-related deposits that are not included in trust, investment and other servicing fees. Based on analysis of historical trends and current asset and product mix, management estimates that a 10% rise or fall in overall equity markets would cause a corresponding increase or decrease in trust, investment and other servicing fees of approximately 4% and total revenues of approximately 2%.

Trust, investment and other servicing fees from C&IS in the quarter increased 8% to a record $274.2 million from the year-ago quarter, reflecting strong new business and higher equity markets. Growth in our international business resulted in a 12% increase in custody and fund administration fees to $140.7 million. Custody and fund administration fees in the prior year quarter included a nonrecurring revenue accrual of approximately $4.5 million. Securities lending fees totaled $45.6 million, down 6% compared with the exceptionally strong performance last year. Results were impacted by lower spreads on the investment of cash collateral, offset in part by higher volumes. Fees from asset management in the quarter grew 12% from the prior year to $71.5 million.

C&IS assets under custody totaled $3.5 trillion at March 31, 2007, up 20% from a year ago, and included $1.8 trillion of global custody assets, a 30% increase compared with a year ago. C&IS assets under management totaled $616.5 billion, a 16% increase from the prior year. As of the current quarter-end, C&IS managed assets were invested 32% in equities, 12% in fixed-income securities, and 56% in cash and other assets.

Noninterest Income (continued)

Trust, investment and other servicing fees from PFS in the quarter increased 14% and totaled a record $214.7 million compared with $188.9 million a year ago. The increase in PFS fees resulted primarily from strong new business results and higher equity markets. Revenue growth continued to be broad-based, with all regions and the Wealth Management Group reporting year-over-year increases in fees. PFS assets under custody totaled $291.8 billion at March 31, 2007, a 24% increase from $235.6 billion in the prior year. PFS assets under management totaled $139.3 billion, a 15% increase from $121.5 billion last year. As of the current quarter-end, PFS managed assets were invested 48% in equities, 33% in fixed-income securities, and 19% in cash and other assets.

Foreign exchange trading income of $67.2 million increased 20% from the prior year quarter, primarily driven by strong client volumes. Revenues from security commissions and trading income equaled $14.0 million, down 10% from the prior year. Other operating income, the components of which are listed below, was $27.1 million for the first quarter compared with $21.4 million in the same period last year. Approximately half of the increase in the other income category reflects the foreign exchange rate impact of translating non-U.S. assets and liabilities.

Net Interest Income

Net interest income for the quarter totaled $194.7 million, 11% higher than the $175.3 million reported in the first quarter of 2006. Net interest income is defined as the total of interest income and amortized fees on earning assets, less interest expense on deposits and borrowed funds, adjusted for the impact of hedging activities. When net interest income is adjusted to a FTE basis, yields on taxable, nontaxable and partially taxable assets are comparable, although the adjustment to a FTE basis has no impact on net income. Net interest income for the quarter, stated on a FTE basis, totaled $210.3 million, up 10% from $190.6 million reported in the prior year quarter. The increase reflects higher levels of average earning assets, partially offset by a decline in the net interest margin. The securities portfolio averaged $12.5 billion, up 13% from last year, with the increase concentrated primarily in variable rate government sponsored agency securities. Average loans and leases increased 9% to $21.4 billion, while money market assets increased 36% from the prior year and averaged $17.0 billion for the quarter. The net interest margin equaled 1.68%, down from 1.79% in the prior year quarter. The decline in the net interest margin reflects the significant growth in global custody-related deposits which have been invested primarily in short-term money market assets and securities.

Average U.S. loans outstanding during the quarter totaled $20.2 billion, 10% higher than the $18.3 billion in last year’s first quarter. Non-U.S. loans decreased $111 million on average from the prior year quarter to $1.2 billion. Residential mortgages averaged $8.7 billion in the quarter, up 4% from the prior year’s first quarter, and represented 41% of the total average loan and lease portfolio. Commercial loans averaged $4.7 billion, up 29% from $3.7 billion last year, while personal loans averaged $3.1 billion, up 6% from last year’s first quarter.

Northern Trust utilizes a diverse mix of funding sources. Total interest-related deposits averaged $36.7 billion, up 29% from the first quarter of 2006. Non-U.S. office time deposits increased $8.0 billion or 41% from last year’s first quarter, resulting primarily from growth in our international business. Retail deposit levels increased $197 million due primarily to higher levels of savings certificates, offset in part by lower balances in savings and now accounts. Other interest-related funds averaged $7.2 billion in the quarter compared with $8.8 billion in last year’s first quarter, and included the proceeds of $250 million of 5.30% fixed-rate, noncallable unsecured notes issued by the Corporation in August of 2006. The balances within these classifications vary based on funding requirements and strategies, interest rate levels, changes in the volume of lower-cost deposit sources, and the availability of collateral to secure these borrowings. Noninterest-related funds utilized to fund earning assets averaged $7.0 billion compared with $6.0 billion in last year’s first quarter.

Provision for Credit Losses

There was no provision for credit losses in the first quarter compared with $4.0 million in the prior year quarter. The reserve for credit losses at March 31, 2007 was $148.8 million compared with $151.0 million at December 31, 2006 and $139.9 million at March 31, 2006. For a discussion of the provision and reserve for credit losses, refer to the “Asset Quality” section beginning on page 27.

Noninterest Expense

Noninterest expenses totaled $525.9 million for the quarter, up 11% from $473.3 million in the year-ago quarter.

Total Noninterest Expenses	$	525.9	$	473.3

Compensation and employee benefit expenses totaled $301.3 million, up $29.3 million or 11% compared with last year. The current quarter increase was driven by increased staff levels, annual salary increases, higher performance-based compensation, and higher health care costs. Staff on a full-time equivalent basis at March 31, 2007 totaled 9,940, up 9% from a year ago.

Other expense categories totaled $224.6 million, up $23.3 million or 12% from $201.3 million last year. The current quarter increase reflects volume driven growth in global subcustody expense, higher expenses for technical and consulting services, a litigation reserve accrual, higher computer software amortization, and increased advertising costs.

Provision for Income Taxes

The provision for income taxes was $95.6 million for the first quarter resulting in an effective tax rate of 33.9%. In the prior year quarter, the provision for income taxes was $87.4 million and the effective tax rate was 34.9%. The lower effective rate reflects management’s decision to reinvest indefinitely the earnings of certain non-U.S. subsidiaries.

Corporate and Institutional Services

C&IS net income for the quarter totaled $117.7 million compared with $99.8 million reported in the first quarter of 2006. Noninterest income was $369.8 million, up 10% from $335.3 million in last year’s first quarter. Trust, investment and other servicing fees increased 8% from the year-ago quarter to a record $274.2 million, reflecting strong new business and higher equity markets. Growth in our international business resulted in a 12% increase in custody and fund administration fees to $140.7 million. Custody and fund administration fees in the prior year quarter included a nonrecurring revenue accrual of approximately $4.5 million. Securities lending fees totaled $45.6 million, down 6% compared with the exceptionally strong performance last year. Results were impacted by lower spreads on the investment of cash collateral, offset in part by higher volumes. Fees from asset management in the quarter grew 12% from the prior year to $71.5 million. Other noninterest income was $95.6 million compared with $81.7 million in last year’s first quarter. The increase is primarily attributable to foreign exchange trading income, which was $65.8 million for the quarter compared with $54.6 million in the first quarter of last year. Treasury management fees were 6% lower in the quarter, offset by higher levels of custody-related deposit revenues.

Net interest income stated on a FTE basis was $87.9 million, up 24% from $70.8 million in last year’s first quarter. The increase reflects higher levels of earning assets. Average earning assets increased $8.0 billion, or 31%, with the increase concentrated in short-term money market assets and loans, and funded primarily with non-U.S. office time deposits. The net interest margin equaled 1.06%, down from 1.12% in the prior year quarter.

The $.4 million provision for credit losses in the current quarter compares with a provision of $4.3 million in the first quarter of last year. The prior year provision was due primarily to growth in the commercial portfolio and the migration of certain loans to higher risk credit ratings. Total noninterest expenses of C&IS, which includes the direct expenses of the business unit, indirect expense allocations from Northern Trust Global Investments (NTGI) and Worldwide Operations and Technology (WWOT) for product and operating support, and indirect expense allocations for certain corporate support services, increased 12% and totaled $267.9 million for the first quarter. The current quarter increase was driven by higher expenses for technical and consulting services, increased performance-based compensation, higher staff levels, annual salary increases, and higher allocations for product and operating support.

Personal Financial Services

PFS net income for the quarter was $85.2 million, up 9% from $78.1 million reported a year ago. Noninterest income was $239.1 million, up 12% from $213.2 million in last year’s first quarter. Trust, investment and other servicing fees in the quarter increased 14% and totaled a record $214.7 million compared with $188.9 million a year ago. The increase in PFS fees resulted primarily from strong new business and higher equity markets. Revenue growth continued to be broad-based, with all regions and the Wealth Management Group reporting year-over-year increases in fees. Other operating income totaled $24.4 million compared with $24.3 million in the prior year quarter.

Net interest income stated on a FTE basis was $125.2 million in the current quarter compared with $123.7 million in the prior year’s first quarter. The increase reflects an 8% increase in average earning assets, concentrated in the loan portfolio, offset by a reduction in the net interest margin from 3.01% last year to 2.82% in the current quarter. The decline in the net interest margin is primarily a result of rising interest rates on deposits and a greater level of funding from short-term borrowings.

A negative provision for credit losses of $.4 million was recorded in the current quarter compared with a negative provision of $.3 million recorded last year. Total noninterest expenses of PFS, which includes the direct expenses of the business unit, indirect expense allocations from NTGI and WWOT for product and operating support, and indirect expense allocations for certain corporate support services, increased 8% to $225.6 million from $209.7 million in last year’s first quarter. The current quarter increase reflects higher performance-based compensation, annual salary increases, and allocations for product and operating support.

Treasury and Other

Treasury and Other includes income and expense associated with the wholesale funding activities and the investment portfolios of the Corporation and the Bank. Treasury and Other also includes certain corporate-based expenses and nonrecurring items not allocated to the business units and certain executive level compensation. Net interest income for the first quarter was a negative $2.8 million compared with a negative $3.9 million in the year-ago quarter. Noninterest expenses totaled $32.4 million for the quarter, compared with $25.1 million in the year-ago period, and includes a litigation reserve accrual.

BALANCE SHEET

Total assets at March 31, 2007 were $59.5 billion and averaged $57.0 billion for the first quarter, compared with last year’s average of $49.7 billion. Loans and leases totaled $21.7 billion at March 31, 2007 and averaged $21.4 billion for the first quarter, compared with $20.0 billion at March 31, 2006 and the $19.6 billion average for the first quarter last year. Securities totaled $12.6 billion at March 31, 2007 and averaged $12.5 billion for the quarter, compared with $11.1 billion at March 31, 2006 and $11.1 billion on average last year. Money market assets totaled $19.5 billion at March 31, 2007. Money market assets averaged $17.0 billion in the first quarter, up 36% from the year-ago quarter. The growth in total assets was funded primarily through an increase in non-U.S. office time deposits, which averaged $27.4 billion in the quarter, up 41% from the year-ago quarter, offset in part by a reduction in short-term borrowings, which averaged $3.9 billion, down 28% from the year-ago quarter.

Common stockholders’ equity increased to $4.0 billion at March 31, 2007 and averaged $3.9 billion for the quarter, up 9% from last year’s first quarter. The increase primarily reflects the retention of earnings offset in part by the impact of adopting new accounting standards and the repurchase of common stock pursuant to the Corporation’s share buyback program.

The December 31, 2006 adoption of a new accounting standard relating to defined benefit pension and other postretirement plans reduced stockholders’ equity by $160.8 million due to the requirement that employers recognize any previously unrecognized actuarial gains/losses and prior service costs, net of tax, in accumulated other comprehensive income. On January 1, 2007, Northern Trust adopted FSP 13-2 related to the accounting for projected changes in leveraged lease cash flows which reduced retained earnings by $72.3 million. In response to the capital impact of adopting these new accounting standards, the Corporation reduced repurchases under the share buyback program in the first quarter of 2007, repurchasing 43,364 shares at a cost of $2.7 million ($61.23 average price per share). An additional 11.9 million shares are authorized for repurchase after March 31, 2007 under the previously announced share buyback program.

Northern Trust’s risk-based capital ratios remained strong at March 31, 2007 and were well above the minimum regulatory requirements of 4% for tier 1 and 8% for total risk-based capital ratios. Northern Trust’s leverage ratio (tier 1 capital to first quarter average assets) at March 31, 2007 also exceeded the minimum regulatory requirement of 3%. Shown below are the March 31, 2007 and March 31, 2006 capital ratios of Northern Trust and of the Bank.


	March 31, 2007				March 31, 2006
Capital Ratios	Northern Trust		The Northern Trust Company		Northern Trust		The Northern Trust Company
Tier 1 Capital	10.2	%	9.3	%	10.2	%	8.4	%
Total Capital	12.4	%	11.7	%	12.7	%	11.4	%
Leverage Ratio	7.0	%	6.0	%	7.0	%	5.6	%

Each of Northern Trust’s other subsidiary banks had March 31, 2007 ratios of 10.4% or higher for tier 1 capital, 11.0% or higher for total risk-based capital, and 8.4% or higher for the leverage ratio.

ASSET QUALITY

Nonperforming assets consist of nonaccrual loans and Other Real Estate Owned (OREO). Nonperforming assets at March 31, 2007 totaled $37.0 million compared with $37.1 million at December 31, 2006 and $31.2 million at March 31, 2006. Nonaccrual loans and leases totaled $35.1 million or .16% of total loans and leases at March 31, 2007. At December 31, 2006 and March 31, 2006, nonaccrual loans and leases totaled $35.7 million and $31.1 million, respectively. The $.6 million decrease in nonperforming loans during the quarter is primarily the result of the full repayment received on one nonperforming loan and the partial charge-off of another, partially offset by the reclassification of three loans to nonperforming.

The following table presents the outstanding amounts of nonaccrual loans and OREO. Also shown are loans that have interest or principal payments that are delinquent 90 days or more and are still accruing interest. The balance of loans delinquent 90 days or more and still accruing interest can fluctuate widely based on the timing of cash collections, renegotiations and renewals.

Provision and Reserve for Credit Losses

The provision for credit losses is the charge to current earnings that is determined by management, through a disciplined credit review process, to be the amount needed to maintain a reserve that is sufficient to absorb probable credit losses that have been identified with specific borrower relationships (specific loss component) and for probable losses that are believed to be inherent in the loan and lease portfolios, unfunded commitments, and standby letters of credit (inherent loss component).

Note 6 to the consolidated financial statements includes a table that details the changes in the reserve for credit losses during the three month periods ended March 31, 2007 and March 31, 2006 due to charge-offs, recoveries, and the provision for credit losses during the respective periods. The following table shows (i) the specific portion of the reserve, (ii) the allocated portion of the inherent reserve and its components by loan category, and (iii) the unallocated portion of the inherent reserve at March 31, 2007, December 31, 2006 and March 31, 2006.

Unfunded Commitments and Standby Letters of Credit		10.5				10.6				10.6

Total Reserve	$	148.8			$	151.0			$	139.9

Specific Component of Reserve. At March 31, 2007, the specific component of the reserve stood at $16.4 million compared with $19.6 million at December 31, 2006. The $3.2 million decrease in specific reserves from December 31, 2006 is primarily due to the partial charge-off of one nonperforming loan and the full repayment received on another.

Allocated Inherent Component of Reserve. The allocated inherent portion of the reserve totaled $106.9 million at March 31, 2007 compared with $106.1 million at December 31, 2006. This component of the reserve increased by $.8 million primarily due to the growth in the commercial loan portfolio offset in part by principal repayments received on lower rated loans.

Unallocated Inherent Component of Reserve. The unallocated portion of the inherent loss reserve is based on management’s review of other factors affecting the determination of probable inherent losses, primarily in the commercial portfolio, which are not necessarily captured by the application of historical loss ratios. This portion of the reserve analysis involves the exercise of judgment and reflects considerations such as management’s view that the reserve should have a margin that recognizes the imprecision inherent in the process of estimating probable credit losses. The unallocated inherent portion of the reserve was $25.5 million at March 31, 2007.

Other Factors. At March 31, 2007, the total amount of the two highest risk loan groupings, those rated “7” and “8” (based on Northern Trust’s internal rating scale, which closely parallels that of the banking regulators) was $79 million of which $31.8 million was classified as impaired, down from $82 million at December 31, 2006 when $31.9 million was classified as impaired, and up from $73 million at March 31, 2006 when $27.8 million was classified as impaired.

Provision and Reserve for Credit Losses (continued)

Overall Reserve. Management’s evaluation of the factors above resulted in a reserve for credit losses of $148.8 million at March 31, 2007. The reserve of $138.3 million assigned to loans and leases, as a percentage of total loans and leases was .64% at March 31, 2007, compared with .62% at December 31, 2006.

Reserves assigned to unfunded loan commitments and standby letters of credit, recorded as a liability on the consolidated balance sheet totaled $10.5 million at March 31, 2007, down slightly from $10.6 million at December 31, 2006.

Provision. There was no provision for credit losses in the first quarter of 2007 compared with a provision of $4.0 million in the prior year quarter.

MARKET RISK MANAGEMENT

As described in the 2006 Financial Annual Report to Shareholders, Northern Trust manages its interest rate risk through measurement techniques which include simulation of earnings, simulation of the economic value of equity, and gap analysis. Also, as part of its risk management activities, it regularly measures the risk of loss associated with foreign currency positions using a value at risk model.

Based on this continuing evaluation process, Northern Trust’s interest rate risk position and the value at risk associated with the foreign exchange trading portfolio have not changed significantly since December 31, 2006.
