FIRST QUARTER CONSOLIDATED RESULTS OF OPERATIONS

General

The Corporation is a leading provider of wealth management, asset servicing, asset management and banking solutions to corporations, institutions, families and individuals. The Corporation focuses on managing and servicing client assets through its two client-focused reporting segments: Asset Servicing and Wealth Management. During the first quarter of 2022, the Corporation changed the name of its Corporate & Institutional Services (C&IS) segment to “Asset Servicing.” Accordingly, the disclosures herein and all future disclosures regarding the Corporation’s reporting segments filed with, or furnished to, the SEC will refer to this segment as Asset Servicing. Asset management and related services are provided to Asset Servicing and Wealth Management clients primarily by the Asset Management business. Except where the context requires otherwise, the terms “Northern Trust,” “we,” “us,” “our,” “its,” or similar terms mean the Corporation and its subsidiaries on a consolidated basis.

COVID-19 Pandemic and Recent Events

Since the start of the COVID-19 pandemic, Northern Trust has remained focused on the health and well-being of our workforce, meeting our clients’ needs and supporting our communities. With the overall improvement in COVID-19 virus trends, and guided by public health and safety recommendations and government regulations, we have begun to safely return to our offices in most locations, across all of our regions—consistent with our established protocols. We continue to provide our workforce with resources to facilitate this return to the office. We remain committed to closely monitoring the situation in all our locations and responding appropriately.

During the pandemic, Northern Trust offered credit assistance to impacted clients under a government lending program and provided payment deferrals. The number of loans under the government lending program, as well as the number of pandemic-related payment deferrals, have declined since the start of the pandemic. For further information, please refer to Note 6 — Loans and Leases to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).

Overview of Financial Results

Net Income per diluted common share increased in the current quarter to $1.77 from $1.70 in the first quarter of 2021. Net Income increased $14.2 million, or 4%, to $389.3 million in the current quarter from $375.1 million in the prior-year quarter. Annualized return on average common equity was 14.2% in the current quarter and 13.7% in the prior-year quarter. The annualized return on average assets was 0.97% in the current quarter as compared to 0.99% in the prior-year quarter.

Revenue increased $135.3 million, or 9%, to $1.72 billion in the current quarter from $1.58 billion in the prior-year quarter.

Beginning in 2022, Trust, Investment and Other Servicing fees were impacted by the change in classification of certain fees that were previously recorded in Other Operating Income or as a reduction of Other Operating Expense. This change resulted in no impact to Net Income. The accounting reclassification increased Trust, Investment and Other Servicing fees in the current quarter by $18.5 million, with a $6.9 million decrease in Other Operating Income and a $11.6 million increase in Other Operating Expense. The classification changes are considered by the Corporation’s management to be a better representation of the underlying nature of the business as they are directly tied to client asset levels and the related services are more akin to our core service offerings. Prior-period amounts have not been reclassified.

Trust, Investment and Other Servicing Fees increased $104.7 million, or 10%, from $1.06 billion in the prior-year quarter to $1.17 billion in the current quarter, primarily due to favorable markets, new business and the accounting reclassification previously discussed.

Other Noninterest Income decreased $10.3 million, or 6%, from $179.6 million in the prior-year quarter to $169.3 million in the current quarter, primarily reflecting lower Other Operating Income, partially offset by higher Foreign Exchange Trading Income.

FIRST QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)

Overview of Financial Results (continued)

Net Interest Income increased $40.9 million, or 12%, to $381.0 million in the current quarter as compared to $340.1 million in the prior-year quarter, primarily due to higher average earning assets and a higher net interest margin.

There was a $2.0 million provision in the current quarter, as compared to a $30.0 million release of credit reserves in the prior-year quarter. The current quarter provision was primarily due to an increase in the reserve evaluated on an individual basis for two commercial borrowers, partially offset by a slight decrease in the reserve evaluated on a collective basis. The reserve evaluated on a collective basis relates to pooled financial assets sharing similar risk characteristics. The decrease in the collective basis reserve was primarily due to continued improvements in credit quality mainly within the commercial real estate portfolio, partially offset by increases in the reserve driven by projected economic conditions.

Noninterest Expense increased $88.4 million, or 8%, from $1.12 billion in the prior-year quarter to $1.21 billion in the current quarter, primarily attributable to higher Compensation, Outside Services, Equipment and Software expense, and Other Operating Expense.

The Provision for Income Taxes in the current quarter totaled $121.5 million, representing an effective tax rate of 23.8%. The Provision for Income Taxes in the prior-year quarter totaled $120.8 million, representing an effective tax rate of 24.4%. The effective tax rate decreased compared to the prior-year quarter primarily due to a lower net tax impact from international operations.

Trust, Investment and Other Servicing Fees

Trust, Investment and Other Servicing Fees are based primarily on the market value of assets held in custody, managed or serviced; the volume of transactions; securities lending volume and spreads; and fees for other services rendered. Certain market value calculations on which fees are based are performed on a monthly or quarterly basis in arrears. Low-interest-rate environments have historically had a negative impact on fees earned on certain products. Certain fees associated with money market mutual funds were waived by the Corporation due to the low-interest-rate environment. Northern Trust voluntarily waived $50.7 million and $50.2 million of money market mutual fund fees for the three months ended March 31, 2022 and 2021, respectively. These fee waivers are impacted by the level of yields earned and account balances in certain funds, as the yields in these funds remained insufficient to pay the stated fees associated with such funds. Fee waivers are expected to decline to the extent the increase in short-term interest rates experienced during the first quarter of 2022 continues.

Beginning in 2022, Trust, Investment and Other Servicing Fees were impacted by the change in classification of certain fees that were previously recorded in Other Operating Income or as a reduction of Other Operating Expense. The impact to Trust, Investment and Other Servicing Fees in the current quarter was $18.5 million, with $6.9 million relating to amounts previously recorded in Other Operating Income and $11.6 million relating to amounts previously reported as a reduction of Other Operating Expense. Prior-period amounts have not been reclassified.

The components of Trust, Investment and Other Servicing Fees are provided below.

FIRST QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)

Trust, Investment and Other Servicing Fees (continued)

Asset Servicing

Custody and Fund Administration fees, the largest component of Asset Servicing fees, are driven primarily by values of client assets under custody/administration (AUC/A), transaction volumes and the number of accounts. The asset values used to calculate these fees vary depending on the individual fee arrangements negotiated with each client. Custody fees related to asset values are client-specific and are priced based on month-end market values, quarter-end market values, or the average of month-end market values for the quarter. The fund administration fees that are asset-value-related are priced using month-end, quarter-end, or average daily balances. Investment Management fees are based generally on market values of client assets under management throughout the period. Typically, the asset values used to calculate fee revenue are based on a one-month or one-quarter lag. Securities Lending revenue is affected by market values; the demand for securities to be lent, which drives volumes; and the interest rate spread earned on the investment of cash deposited by investment firms as collateral for securities they have borrowed. The Other fee category in Asset Servicing includes such products as investment risk and analytical services, benefit payments, and other services. Revenue from these products is based generally on the volume of services provided or a fixed fee.

Custody and Fund Administration fees increased from the prior-year quarter, primarily due to favorable markets and new business, partially offset by unfavorable currency translation and lower transaction volumes.

Investment Management fees increased from the prior-year quarter, primarily due to new business, the accounting reclassification previously discussed, and favorable markets.

Other fees increased from the prior-year quarter primarily due to the accounting reclassification previously discussed.

Wealth Management

Wealth Management fee income is calculated primarily based on market values and is impacted by both one-month and one-quarter lagged asset values. Fee income in the regions (Central, East and West) increased from the prior-year quarter, primarily due to favorable markets, new business and the accounting reclassification previously discussed. Global Family Office fee income increased from the prior-year quarter, primarily due to new business, favorable markets, and the accounting reclassification previously discussed.

Beginning in 2022, Other Operating Income was impacted by the change in classification of certain fees to Trust, Investment and Other Servicing Fees. The impact to Other Operating Income in the current quarter was $6.9 million relating to amounts now recorded in Trust, Investment and Other Servicing Fees. Prior-period amounts have not been reclassified.

Foreign Exchange Trading Income increased compared to the prior-year quarter primarily due to higher client volumes and market volatility.

Other Operating Income decreased compared to the prior-year quarter, primarily driven by the accounting reclassification previously discussed and lower miscellaneous income. The lower miscellaneous income was primarily associated with a market

Please refer to Note 16 — Other Operating Income to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited) for further detail.

Net Interest Income

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 interest-related hedging activity. Earning assets—including Federal Funds Sold, Securities Purchased under Agreements to Resell, Interest-Bearing Due From Banks, Federal Reserve and Other Central Bank Deposits and Other, Securities, and Loans and Leases—are financed by a large base of interest-bearing funds that include client deposits, short-term borrowings, Senior Notes and Long-Term Debt. Short-term borrowings include Federal Funds Purchased, Securities Sold Under Agreements to Repurchase, and Other Borrowings. Earning assets are also funded by noninterest-related funds, which include demand deposits and stockholders’ equity. Net Interest Income is subject to variations in the level and mix of earning assets and interest-bearing funds and their relative sensitivity to interest rates. In addition, the levels of nonaccruing assets and client compensating deposit balances used to pay for services impact Net Interest Income.

Net interest margin is the difference between what we earn on our assets and what we pay for deposits and other sources of funding. The direction and level of interest rates are important factors in our earnings. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.

Net Interest Income stated on a fully taxable equivalent (FTE) basis is a non-generally accepted accounting principle (GAAP) financial measure that facilitates the analysis of asset yields. Management believes an FTE presentation provides a clearer indication of net interest margins for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on Net Income. A reconciliation of Net Interest Income on a GAAP basis to Net Interest Income on an FTE basis is provided in “Reconciliation to Fully Taxable Equivalent” within this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section.

(1)Changes not due solely to average balance changes or rate changes are allocated proportionately to average balance and rate based on their relative absolute magnitudes.

Notes:    Net Interest Income (FTE Adjusted), a non-GAAP financial measure, includes adjustments to a fully taxable equivalent basis for loans and securities. The adjustments are based on a federal income tax rate of 21.0%, where the rate is adjusted for applicable state income taxes, net of related federal tax benefit. Total taxable equivalent interest adjustments amounted to $6.7 million and $6.6 million for the three months ended March 31, 2022 and 2021, respectively. A reconciliation of Net Interest Income and net interest margin on a GAAP basis to Net Interest Income and net interest margin on an FTE basis (each of which is a non-GAAP financial measure) is provided in “Reconciliation to Fully Taxable Equivalent” within this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section. Net interest margin is calculated by dividing annualized Net Interest Income by average interest-earning assets.

Interest revenue on cash collateral positions is reported above in Interest-Bearing Due from and Deposits with Banks and in Loans and Leases. Interest Expense on cash collateral positions is reported above in Non-U.S. Offices Interest-Bearing Deposits. Related cash collateral received from and deposited with derivative counterparties is recorded net of the associated derivative contract in Other Assets and Other Liabilities, respectively.

Net Interest Income, stated on a FTE basis, increased from the prior-year quarter, primarily due to higher average earning assets and a higher net interest margin. Average earning assets increased from the prior-year quarter, primarily due to higher levels of net short-term interest-bearing deposits with central banks and banks, as well as loans, partially offset by lower levels of securities.

The net interest margin on an FTE basis increased from the prior-year quarter, primarily driven by a favorable balance sheet volume and mix shift. Net interest margin is expected to benefit in the future from the recent and anticipated increases in short-term interest rates.

Federal Reserve and Other Central Bank Deposits and Other averaged $45.2 billion and increased $8.1 billion, or 22%, from $37.1 billion in the prior-year quarter, resulting from increased deposit inflows. The higher level of client deposits were primarily placed with the Federal Reserve and other central banks and in loans. Average Securities were $59.9 billion and decreased $1.3 billion, or 2%, from $61.2 billion, in the prior-year quarter and include certain community development investments, Federal Home Loan Bank stock, and Federal Reserve stock of $962.8 million, $70.1 million and $70.0 million, respectively, which are recorded in Other Assets on the consolidated balance sheets. Average taxable Securities were $57.4 billion in the current quarter and $57.5 billion in the prior-year quarter. Average nontaxable Securities, which represent securities that are primarily exempt from U.S. federal and state income taxes, were $2.5 billion in the current quarter and

10

FIRST QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)

Net Interest Income (continued)

$3.7 billion in the prior-year quarter. Interest-Bearing Due from and Deposits with Banks averaged $4.4 billion in the current quarter and $6.5 billion in the prior-year quarter.

Loans and Leases averaged $39.5 billion and increased $5.3 billion, or 16%, from $34.2 billion in the prior-year quarter, primarily reflecting higher levels of private client, commercial and institutional, commercial real estate, non-U.S., and residential real estate loans. Private client loans averaged $14.1 billion and increased $2.3 billion, or 19%, from $11.8 billion for the prior-year quarter. Commercial and institutional loans averaged $11.7 billion and increased $1.8 billion, or 19%, from $9.9 billion for the prior-year quarter. Commercial real estate loans averaged $4.3 billion and increased $643.8 million, or 18%, from $3.7 billion for the prior-year quarter. Non-U.S. loans averaged $2.9 billion and increased $540.6 million or 23%, from $2.3 billion for the prior-year quarter. Residential real estate loans averaged $6.2 billion and increased $66.2 million, or 1%, from $6.1 billion for the prior-year quarter.

Northern Trust utilizes a diverse mix of funding sources. Average Interest-Bearing Deposits increased $5.4 billion, or 6%, to an average of $101.4 billion in the current quarter from $96.0 billion in the prior-year quarter. Other Average Interest-Related Funds decreased $2.2 billion, or 22%, to an average of $7.5 billion in the current quarter from $9.7 billion in the prior-year quarter. The balances within short-term borrowing 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. Average net noninterest-related funds increased $6.0 billion, or 17%, to $40.9 billion in the current quarter from $34.9 billion in the prior-year quarter, primarily resulting from higher levels of Demand and Other Noninterest-Bearing Deposits.

Interest expense for Interest-Bearing Deposits in the current quarter was driven by low and negative interest rates for Non-U.S. Offices Interest-Bearing Deposits and low interest rates on domestic Interest-Bearing Deposits. Average Non-U.S. Offices Interest-Bearing Deposits comprised 67% of total average Interest-Bearing Deposits for the three months ended March 31, 2022.

Provision for Credit Losses

There was a $2.0 million provision in the current quarter, as compared to a $30.0 million release of credit reserves in the prior-year quarter. The provision in the current quarter was primarily due to an increase in the reserve evaluated on an individual basis for two commercial borrowers, partially offset by a slight decrease in the reserve evaluated on a collective basis. The reserve evaluated on a collective basis relates to pooled financial assets sharing similar risk characteristics. The decrease in the collective basis reserve was primarily due to continued improvements in credit quality mainly within the commercial real estate portfolio, partially offset by increases in the reserve driven by projected economic conditions.

The release of credit reserves in the prior-year quarter was primarily due to a decrease in the reserve evaluated on a collective basis driven by continued improvement in projected economic conditions at the time and portfolio credit quality. Decreases in the collective basis reserve were primarily in the commercial and institutional, commercial real estate and private client portfolios.

Net recoveries in the current quarter were $3.2 million, reflecting $3.3 million of recoveries and $0.1 million of charge-offs. The prior-year quarter included $0.9 million of net recoveries, reflecting $1.3 million of recoveries and $0.4 million of charge-offs. Nonaccrual assets of $101.0 million decreased $24.3 million, or 19%, from $125.3 million at the end of the prior-year quarter.

Commercial real estate, residential real estate, commercial and institutional, and lease financing accounted for 46%, 25%, 18%, and 11%, respectively, of total nonaccrual loans and leases at March 31, 2022. Residential real estate, commercial real estate, commercial and institutional, and private client loans accounted for 48%, 33%, 17%, and 2%, respectively, of total nonaccrual loans and leases at March 31, 2021. For additional discussion of the allowance for credit losses, refer to the “Asset Quality” section in this MD&A.

FIRST QUARTER CONSOLIDATED RESULTS OF OPERATIONS (continued)

Noninterest Expense

Beginning in 2022, Other Operating Expense was impacted by the change in classification of certain amounts previously reported as a reduction of Other Operating Expense to Trust, Investment and Other Servicing Fees. The impact to Other Operating Expense in the current quarter was $11.6 million relating to amounts now recorded in Trust, Investment and Other Servicing Fees rather than as a reduction of Other Operating Expenses. Prior-period amounts have not been reclassified.

The components of Noninterest Expense are provided in the following table.

TABLE 15: NONINTEREST EXPENSE

Other Operating Expense	79.7		71.7		8.0		11
Total Noninterest Expense	$	1,205.9	$	1,117.5	$	88.4	8	%

Compensation expense, the largest component of Noninterest Expense, increased compared to the prior-year quarter, primarily due to higher incentives and salary expense.

Outside Services expense increased compared to the prior-year quarter, primarily due to higher technical services costs and consulting services.

Equipment and Software expense increased compared to the prior-year quarter, primarily due to higher software support and rental costs and higher amortization.

Other Operating Expense increased compared to the prior-year quarter, primarily due to the accounting reclassification previously discussed, partially offset by lower supplemental compensation plan expense. The lower supplemental compensation plan expense in the prior-year quarter comparison resulted in a related decrease in miscellaneous income reported in noninterest income. Please refer to Note 17 — Other Operating Expense to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited) for further detail.

Provision for Income Taxes

Income tax expense for the three months ended March 31, 2022 was $121.5 million, representing an effective tax rate of 23.8%, compared to $120.8 million in the prior-year quarter, representing an effective tax rate of 24.4%.

The effective tax rate decreased compared to the prior-year quarter primarily due to a lower net tax impact from international operations.

REPORTING SEGMENTS

During the first quarter of 2022, the Corporation changed the name of its C&IS segment to “Asset Servicing.” Accordingly, the disclosures herein and all future disclosures regarding the Corporation’s reporting segments filed with, or furnished to, the SEC will refer to this segment as Asset Servicing. This change has not had, and is not expected in the future to have, any impact upon the methodology by which the Corporation allocates revenue and expense to each of its reporting segments.

Northern Trust is organized around its two client-focused reporting segments: Asset Servicing and Wealth Management. Asset management and related services are provided to Asset Servicing and Wealth Management clients primarily by the Asset Management business. The revenue and expenses of Asset Management and certain other support functions are allocated fully to Asset Servicing and Wealth Management.

Reporting segment financial information, presented on an internal management reporting basis, is determined by accounting systems used to allocate revenue and expense to each segment, and incorporates processes for allocating assets, liabilities, equity and the applicable interest income and expense utilizing a funds transfer pricing (FTP) methodology. Under the methodology, assets and liabilities receive a funding charge or credit that considers interest rate risk, liquidity risk, and other product characteristics on an instrument level. Additionally, segment information is presented on an FTE basis as management believes an FTE presentation provides a clearer indication of net interest income. The adjustment to an FTE basis has no impact on Net Income.

12

REPORTING SEGMENTS (continued)

Revenues, expenses and average assets are allocated to Asset Servicing and Wealth Management, with the exception of non-recurring activities such as certain costs associated with acquisitions, divestitures, litigation, restructuring, and tax adjustments not directly attributable to a specific reporting segment.

Reporting segment results are subject to reclassification when organizational changes are made. The results are also subject to refinements in revenue and expense allocation methodologies, which are typically reflected on a prospective basis.

The following table presents the earnings contributions and average assets of Northern Trust’s reporting segments for the three months ended March 31, 2022 and 2021.

Asset Servicing

Asset Servicing Net Income

For the quarter ended March 31, 2022, Net Income increased $14.7 million, or 9%, from the prior-year quarter, primarily reflecting higher Trust, Investment and Other Servicing Fees and Net Interest Income, partially offset by higher Noninterest Expense and a Provision for Credit Losses in the current quarter as compared to a release in the prior-year quarter.

Asset Servicing Trust, Investment and Other Servicing Fees

For an explanation of Asset Servicing Trust, Investment, and Other Servicing Fees, please see the “Trust, Investment and Other Servicing Fees” section within the Consolidated Results of Operations section of the MD&A.

Asset Servicing Foreign Exchange Trading Income

For the quarter ended March 31, 2022, Foreign Exchange Trading Income increased $2.9 million, or 4%, from the prior-year quarter, primarily due to higher client volumes and market volatility.

Asset Servicing Other Noninterest Income

For the quarter ended March 31, 2022, Other Noninterest Income increased $0.8 million, or 1.3%, from the prior-year quarter, primarily due to higher Security Commissions and Trading Income, partially offset by lower Other Operating Income. The lower Other Operating Income was driven by the change in classification of certain fees to Trust, Investment and Other Servicing Fees for which prior-period amounts have not been reclassified.

Asset Servicing (continued)

Asset Servicing Net Interest Income

For the quarter ended March 31, 2022, Net Interest Income stated on an FTE basis increased $29.4 million, or 18%, from the prior-year quarter. The increase for the three months ended March 31, 2022 primarily reflected a higher net interest margin and higher average earning asset levels funded by higher deposit balances. Average earning assets increased $5.4 billion to $114.4 billion in the current quarter from $109.0 billion in the prior-year quarter. The earning assets and funding sources in Asset Servicing for the quarter ended March 31, 2022 consisted primarily of intercompany assets and of loans and non-U.S. custody-related interest-bearing deposits, respectively.

Asset Servicing Provision for Credit Losses

For the quarter ended March 31, 2022, there was an $8.4 million Provision for Credit Losses compared to a $5.4 million release of credit reserves in the prior-year quarter. The provision for credit losses in the current quarter was primarily due to an increase in the reserve evaluated on an individual basis and increases in the collective basis reserve driven by projected economic conditions. The reserve evaluated on a collective basis relates to pooled financial assets sharing similar risk characteristics.

Asset Servicing Noninterest Expense

For the quarter ended March 31, 2022, Noninterest Expense, which includes the direct expense of the reporting segment, indirect expense allocations for product and operating support and indirect expense allocations for certain corporate support services, increased $44.8 million, or 6%, from the prior-year quarter, primarily due to higher expense allocations, Other Operating Expense, and Compensation expense. The higher Other Operating Expense was due to the change in classification of certain amounts, previously reported as a reduction of Other Operating Expense, to Trust, Investment and Other Servicing Fees for which prior-periods amounts have not been reclassified.

Wealth Management

Wealth Management Net Income

For the quarter ended March 31, 2022, Net Income increased $1.3 million, or 1%, from the prior-year quarter primarily due to higher Trust, Investment and Other Servicing Fees and Net Interest Income, partially offset by higher Noninterest Expense, a lower release of credit reserves, and lower Other Noninterest Income.

Wealth Management Trust, Investment and Other Servicing Fees

For an explanation of Wealth Management Trust, Investment and Other Servicing Fees, please see the “Trust, Investment and Other Servicing Fees” section within the Consolidated Results of Operations section of the MD&A.

Wealth Management Other Noninterest Income

For the quarter ended March 31, 2022, Other Noninterest Income decreased $12.4 million, or 28%, from the prior-year quarter primarily due to lower Other Operating Income driven by lower income allocations and the change in classification of certain fees to Trust, Investment and Other Servicing Fees for which prior-period amounts have not been reclassified.

Wealth Management Net Interest Income

For the quarter ended March 31, 2022, Net Interest Income stated on an FTE basis increased $11.6 million, or 6%, from the prior-year quarter. The increase for the three months ended March 31, 2022 was primarily due to higher average loans and deposits balances, partially offset by lower average interest rates. Average earning assets increased $3.8 billion to $35.4 billion in the current quarter from $31.6 billion in the prior-year quarter. Earning assets and funding sources for the quarter ended March 31, 2022 were primarily comprised of loans and domestic interest-bearing deposits, respectively.

Wealth Management Provision for Credit Losses

For the quarter ended March 31, 2022, there was a $6.4 million release of credit reserves compared to a $24.6 million release of credit reserves in the prior-year quarter. The release of credit reserves for the quarter ended March 31, 2022, was primarily due to a decrease in the reserve evaluated on a collective basis, which relates to pooled financial assets sharing similar risk characteristics. The decrease in the collective basis reserve was driven by continued improvements in portfolio credit quality mainly within the commercial real estate portfolio, partially offset by increases in the reserve driven by projected economic conditions.

Wealth Management Noninterest Expense

For the quarter ended March 31, 2022, Noninterest Expense, which includes the direct expenses of the reporting segment, indirect expense allocations for product and operating support and indirect expense allocations for certain corporate support services, increased $42.0 million or 10% from the prior-year quarter, primarily reflecting higher expense allocations and Compensation expense.

Average balances are considered to be a better measure of balance sheet trends, as period-end balances can be impacted by the timing of deposit and withdrawal activity involving large client balances. The current-quarter growth in the average consolidated balance sheets was primarily driven by higher customer deposit balances.

Short-Term Borrowings. Short-term borrowings includes Federal Funds Purchased, Securities Sold under Agreements to Repurchase, and Other Borrowings. Securities Sold under Agreements to Repurchase are accounted for as collateralized financings and recorded at the amounts at which the securities were sold plus accrued interest. To minimize any potential credit risk associated with these transactions, the fair value of the securities sold is monitored, limits are set on exposure with

As of March 31, 2022 and December 31, 2021, the 6% and 5%, respectively, of HTM debt securities not rated by Moody’s, S&P Global or Fitch Ratings consisted of certificates of deposit with a remaining life of less than six months, as well as investments purchased by Northern Trust to fulfill its obligations under the Community Reinvestment Act (CRA). Northern Trust fulfills its obligations under the CRA by making qualified investments for purposes of supporting institutions and programs that benefit low-to-moderate income communities within Northern Trust’s market area.

Net unrealized losses within the investment securities portfolio totaled $1.9 billion at March 31, 2022, compared to net unrealized losses of $187.1 million as of December 31, 2021. Net unrealized losses as of March 31, 2022 were comprised of $62.4 million and $1,999.6 million of gross unrealized gains and losses, respectively. Net unrealized losses as of December 31, 2021 were comprised of $345.1 million and $532.2 million of gross unrealized gains and losses, respectively.

As of March 31, 2022, the $36.9 billion AFS debt securities portfolio had unrealized losses of $475.9 million and $256.6 million related to government-sponsored agency securities and obligations of states and political subdivisions, respectively, which are primarily attributable to changes in market interest rates and credit spreads since their purchase. As of December 31, 2021, the $38.0 billion AFS debt securities portfolio had unrealized losses of $110.2 million related to government-sponsored agency securities, which are primarily attributable to changes in market interest rates and credit spreads since their purchase. As of March 31, 2022 and December 31, 2021, 12% and 14%, respectively, of the AFS corporate debt securities portfolio was backed by guarantees provided by U.S. and non-U.S. government entities.

As of March 31, 2022, the $21.2 billion HTM debt securities portfolio had unrealized losses of $400.9 million and $208.2 million related to government-sponsored agency securities and sub-sovereign, supranational and non-U.S. agency bonds, respectively, which are primarily attributable to changes in overall market interest rates and credit spreads since their purchase. As of December 31, 2021, the $23.6 billion HTM debt securities portfolio had an unrealized loss of $106.1 million, $80.0 million and $71.6 million related to government-sponsored agency, sub-sovereign, supranational and non-U.S. agency bonds, and other residential mortgage-backed securities, respectively, which are primarily attributable to changes in overall market interest rates and credit spreads since their purchase.

ASSET QUALITY (continued)

Securities Portfolio (continued)

HTM debt securities consist of securities that management intends to, and Northern Trust has the ability to, hold until maturity. During the three months ended March 31, 2022 and 2021, no securities were transferred from AFS to HTM. Upon transfer of a debt security from the AFS to HTM classification, the amortized cost is reset to fair value. Any net unrealized gain or loss at the date of transfer will remain in AOCI and be amortized into Net Interest Income over the remaining life of the securities using the effective interest method. The amortization of amounts retained in AOCI will offset the effect on interest income of the amortization of the premium or discount resulting from transferring the securities at fair value.

For additional information relating to the securities portfolio, refer to Note 4 — Securities to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).

Securities purchased under agreements to resell and securities sold under agreements to repurchase are accounted for as collateralized financings and recorded at the amounts at which the securities were acquired or sold plus accrued interest. To minimize potential credit risk associated with these transactions, the fair value of the securities purchased or sold is monitored, limits are set on exposure with counterparties, and the financial condition of counterparties is regularly assessed. It is Northern Trust’s policy to take possession, either directly or via third-party custodians, of securities purchased under agreements to resell. Securities sold under agreements to repurchase are held by the counterparty until their repurchase.

For additional information relating to the securities sold under agreements to repurchase, refer to Note 5 — Securities Sold Under Agreements to Repurchase to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).

Nonaccrual Loans and Leases and Other Real Estate Owned

Nonaccrual assets consist of nonaccrual loans and leases and other real estate owned (OREO). OREO is comprised of commercial and residential properties acquired in partial or total satisfaction of loans.

The following table provides the amounts of nonaccrual loans and leases, by loan and lease segment and class, and of OREO that were outstanding at the dates shown, as well as the balance of loans that were delinquent 90 days or more and still accruing interest. Loans that are delinquent 90 days or more and still accruing interest can fluctuate widely based on the timing of cash collections, renegotiation and renewals.

Nonaccrual assets of $101.0 million as of March 31, 2022 decreased from December 31, 2021 primarily due to the payoff of one nonaccrual loan in the commercial real estate portfolio and payoffs in the residential real estate portfolio, partially offset by the addition of one nonaccrual lease in the lease financing portfolio. In addition to the negative impact on Net Interest Income and the risk of credit losses, nonaccrual assets also increase operating costs due to the expense associated with collection efforts. Changes in the level of nonaccrual assets may be indicative of changes in the credit quality of one or more loan classes. Changes in credit quality impact the allowance for credit losses through the resultant adjustment of the allowance evaluated on an individual basis and the quantitative and qualitative factors used in the determination of the allowance evaluated on a collective basis within the allowance for credit losses.

ASSET QUALITY (continued)

Nonaccrual Loans and Leases and Other Real Estate Owned (continued)

Northern Trust’s credit policies do not allow for the origination of loan types generally considered to be high risk in nature, such as option adjustable rate mortgage loans, subprime loans, loans with initial “teaser” rates and loans with excessively high loan-to-value ratios. Residential real estate loans consist of first lien mortgages and equity credit lines, which generally require a loan-to-collateral value of no more than 65% to 80% at inception. Appraisals of supporting collateral for residential real estate loans are obtained at loan origination and upon refinancing or default or when otherwise considered warranted. Residential real estate collateral appraisals are performed and reviewed by independent third parties.

The commercial real estate portfolio consists of commercial mortgages and construction, acquisition and development loans extended primarily to experienced investors well known to Northern Trust. Underwriting standards generally reflect conservative loan-to-value ratios and debt service coverage requirements. Recourse to owners through guarantees also is commonly required.

For additional information relating to the loans and leases portfolio, refer to Note 6 — Loans and Leases to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).

Allowance for Credit Losses

The allowance for credit losses—which represents management’s best estimate of lifetime expected credit losses related to various portfolios subject to credit risk, off-balance-sheet credit exposure, and specific borrower relationships—is determined by management through a disciplined credit review process. Northern Trust measures expected credit losses of financial assets with similar risk characteristics on a collective basis. A financial asset is measured individually if it does not share similar risk characteristics with other financial assets and the related allowance is determined through an individual evaluation.

Management’s estimates utilized in establishing an appropriate level of allowance for credit losses are not dependent on any single assumption. In determining an appropriate allowance level, management evaluates numerous variables, many of which are interrelated or dependent on other assumptions and estimates, and takes into consideration past events, current conditions and reasonable and supportable forecasts.

The results of the credit reserve estimation methodology are reviewed quarterly by Northern Trust’s Credit Loss Reserve Committee, which receives input from Credit Risk Management, Treasury, Corporate Finance, the Economic Research group, and each of Northern Trust’s business units.

As of March 31, 2022, the allowance for credit losses related to loans and leases, undrawn loan commitments and standby letters of credit, HTM debt securities, AFS debt securities, and other financial assets, was $136.3 million, $37.5 million, $14.6 million, $0.4 million and $1.1 million, respectively. As of December 31, 2021, the allowance for credit losses related to loans and leases, undrawn loan commitments and standby letters of credit, HTM debt securities, and other financial assets, was $138.4 million, $34.1 million, $11.2 million, and $1.0 million, respectively. There was no allowance for credit losses related to AFS debt securities as of December 31, 2021. For additional information relating to the allowance for credit losses and the changes in the allowance for credit losses during the three months ended March 31, 2022 and 2021 due to charge-offs, recoveries and provisions for credit losses, refer to Note 7 — Allowance for Credit Losses to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited). The following table shows the allowance evaluated on an individual and collective basis for the loans and leases portfolio by segment and class.

Operating Activities

Net cash provided by operating activities of $746.9 million for the three months ended March 31, 2022 was primarily attributable to net changes in other operating activities, period earnings, decrease in receivables and the impact of lower non-cash charges such as depreciation and amortization, partially offset by higher net collateral deposited with derivative counterparties.

Net cash provided by operating activities of $68.3 million for the three months ended March 31, 2021 was primarily attributable to period earnings, the impact of lower non-cash charges such as amortization and net changes in other operating activities, partially offset by higher net collateral deposited with derivative counterparties.

Net cash provided by investing activities of $10.3 billion for the three months ended March 31, 2022 was primarily attributable to decreased levels of Federal Reserve and other central bank deposits, net proceeds associated with HTM debt securities and lower levels of loans and leases, partially offset by higher levels of interest-bearing deposits with banks and securities purchased under agreements to resell.

Net cash provided by investing activities of $5.1 billion for the three months ended March 31, 2021 was primarily attributable to decreased levels of Federal Reserve and other central bank deposits, partially offset by net purchases of debt securities available for sale, client security settlement receivables, and interest-bearing deposits with banks.

STATEMENTS OF CASH FLOWS (continued)

Financing Activities

Net cash used in financing activities of $10.3 billion for the three months ended March 31, 2022 was primarily attributable to the decreased levels of total deposits and securities sold under agreements to repurchase. The decrease in total deposits was primarily attributable to lower levels of interest-bearing non-U.S office client deposits, savings, money market and other interest-bearing deposits, and non-U.S. office noninterest-bearing deposits, partially offset by increased domestic noninterest-bearing deposits.

Net cash used in financing activities of $4.9 billion for the three months ended March 31, 2021 was primarily attributable to the decreased levels of total deposits, partially offset by increased levels of short-term borrowings. The decrease in total deposits was primarily attributable to lower levels of interest-bearing non-U.S. office client deposits, and savings, money market and other interest-bearing deposits, partially offset by increased non-U.S. and domestic noninterest-bearing deposits.

CAPITAL RATIOS

The capital ratios of Northern Trust Corporation and its principal subsidiary, The Northern Trust Company, remained strong at March 31, 2022, exceeding the requirements for classification as “well-capitalized” under applicable U.S. regulatory requirements.

The results of the 2021 Dodd-Frank Act Stress Test, published by the Federal Reserve on June 24, 2021, resulted in Northern Trust’s stress capital buffer and effective Common Equity Tier 1 capital ratio minimum requirement remaining at 2.5% for the annual Capital Plan cycle beginning on October 1, 2021.

An increase in accumulated other comprehensive loss, which was primarily due to an increase in net unrealized losses on the available for sale debt securities portfolio largely from rising interest rates, contributed to the current quarter’s change in capital ratios from the prior period.

The table below provides capital ratios, as well as the required minimum capital ratios, for Northern Trust Corporation and The Northern Trust Company determined by Basel III phased-in requirements.

(1) In November 2019, the Federal Reserve and other U.S. federal banking agencies adopted a final rule that established a deduction for central bank deposits from the total leverage exposures of custodial banking organizations, including the Corporation and the Bank, equal to the lesser of (i) the total amount of funds the custodial banking organization and its consolidated subsidiaries have on deposit at qualifying central banks and (ii) the total amount of client funds on deposit at the custodial banking organization that are linked to fiduciary or custodial and safekeeping accounts. The rule became effective on April 1, 2020. The supplementary leverage ratios at March 31, 2022, December 31, 2021 and March 31, 2021 for the Northern Trust Corporation and The Northern Trust Company reflect the impact of this final rule.

RECENT ACCOUNTING PRONOUNCEMENTS AND DEVELOPMENTS

In March 2022, the Financial Accounting Standards Board (FASB) issued ASU No. 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method” (ASU 2022-01). The amendments in ASU 2022-01 expand the current last-of-layer hedging model from a single-layer method to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. In addition, ASU 2022-01 (1) expands the scope of the portfolio layer method to include non-prepayable assets, (2) specifies eligible hedging instruments in a single-layer hedge, (3) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method and (4) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. ASU 2022-01 is effective for interim and annual periods beginning after December 15, 2022, although early adoption is permitted. Upon adoption, ASU 2022-01 is not expected to have a significant impact on Northern Trust’s consolidated financial condition or results of operations.

In March 2022, the Financial Accounting Standards Board (FASB) issued ASU No. 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (ASU 2022-02). The amendments in ASU 2022-02 eliminate the accounting guidance for troubled debt restructurings (“TDRs”) for creditors that have adopted CECL while enhancing disclosure requirements for certain loan refinancings and restructurings made to borrowers experiencing financial difficulty. In addition, ASU 2022-02 requires that a public business entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases. ASU 2022-02 is effective for interim and annual periods beginning after December 15, 2022, although early adoption is permitted. Northern Trust is currently assessing the impact of adoption of ASU 2022-02.

MARKET RISK MANAGEMENT

There are two types of market risk, interest rate risk associated with the banking book and trading risk. Interest rate risk associated with the banking book is the potential for movements in interest rates to cause changes in net interest income and the market value of equity. Trading risk is the potential for movements in market variables such as foreign exchange and interest rates to cause changes in the value of trading positions.

Northern Trust uses two primary measurement techniques to manage interest rate risk: Net Interest Income (NII) sensitivity and Market Value of Equity (MVE) sensitivity. NII sensitivity provides management with a short-term view of the impact of interest rate changes on NII. MVE sensitivity provides management with a long-term view of interest rate changes on MVE based on the period-end balance sheet.

As part of its risk management activities, Northern Trust also measures daily the risk of loss associated with all non-U.S. currency positions using a Value-at-Risk (VaR) model and applying the historical simulation methodology. The following information about Northern Trust’s management of market risk should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2021.

NII Sensitivity — The modeling of NII sensitivity incorporates on-balance-sheet positions, as well as derivative financial instruments (principally interest rate swaps) that are used to manage interest rate risk. Northern Trust uses market implied forward interest rates as the base case and measures the sensitivity (i.e., change) of a static balance sheet to changes in interest rates. Stress testing of interest rates is performed to include such scenarios as immediate parallel shocks to rates, nonparallel (i.e., twist) changes to yield curves that result in their becoming steeper or flatter, and changes to the relationship among the yield curves (i.e., basis risk).

The NII sensitivity analysis incorporates certain critical assumptions such as interest rates and client behaviors under changing rate environments. These assumptions are based on a combination of historical analysis and future expected pricing behavior. The simulation cannot precisely estimate NII sensitivity given uncertainty in the assumptions. The following key assumptions are incorporated into the simulation:

▪the balance sheet size and mix remains constant over the simulation horizon with maturing assets and liabilities replaced with instruments with similar terms as those that are maturing, with the exception of certain nonmaturity deposits that are considered short-term in nature and therefore receive a more conservative interest-bearing treatment;

▪prepayments on mortgage loans and securities collateralized by mortgages are projected under each rate scenario using a third-party mortgage analytics system that incorporates market prepayment assumptions;

▪cash flows for structured securities are estimated using a third-party vendor in conjunction with the prepayments provided by the third-party mortgage analytics vendor;

▪nonmaturity deposit pricing is projected based on Northern Trust’s actual historical patterns and management judgment, depending upon the availability of historical data and current pricing strategies/or judgment; and

▪new business rates are based on current spreads to market indices.

22

MARKET RISK MANAGEMENT (continued)

The following table shows the estimated NII impact over the next twelve months of 100 and 200 basis point ramps upward and 100 basis point ramp downward movements in interest rates relative to forward rates. Each rate movement is assumed to occur gradually over a one-year period.

TABLE 25: NET INTEREST INCOME SENSITIVITY AS OF MARCH 31, 2022

($ In Millions)	INCREASE (DECREASE) ESTIMATED IMPACT ON NEXT TWELVE MONTHS OF NET INTEREST INCOME
Increase in Interest Rates Above Market Implied Forward Rates
100 Basis Points	$	107
200 Basis Points	234
Decrease in Interest Rates Below Market Implied Forward Rates
100 Basis Points	$	(154)

The NII sensitivity analysis does not incorporate certain management actions that may be used to mitigate adverse effects of actual interest rate movement. For that reason and others, the estimated impacts do not reflect the likely actual results but serve as estimates of interest rate risk. NII sensitivity is not comparable to actual results disclosed elsewhere or directly predictive of future values of other measures provided.

MVE Sensitivity — MVE is defined as the present value of assets minus the present value of liabilities, net of the value of financial derivatives that are used to manage the interest rate risk of balance sheet items. The potential effect of interest rate changes on MVE is derived from the impact of such changes on projected future cash flows and the present value of these cash flows and is then compared to the established limit. Northern Trust uses current market rates (and the future rates implied by these market rates) as the base case and measures MVE sensitivity under various rate scenarios. Stress testing of interest rates is performed to include such scenarios as immediate parallel shocks to rates, nonparallel (i.e., twist) changes to yield curves that result in their becoming steeper or flatter, and changes to the relationship among the yield curves (i.e., basis risk).

The MVE sensitivity analysis incorporates certain critical assumptions such as interest rates and client behaviors under changing rate environments. These assumptions are based on a combination of historical analysis and future expected pricing behavior. The simulation cannot precisely estimate MVE sensitivity given uncertainty in the assumptions. Many of the assumptions that apply to NII sensitivity also apply to MVE sensitivity simulations, with the following separate key assumptions incorporated into the MVE simulation:

▪the present value of nonmaturity deposits are estimated using dynamic decay methodologies or estimated remaining lives, which are based on a combination of Northern Trust’s actual historical runoff patterns and management judgment—some balances are assumed to be core and have longer lives while other balances are assumed to be temporary and have comparatively shorter lives;

▪the present values of most noninterest-related balances (such as receivables, equipment, and payables) are the same as their book values; and

▪Monte Carlo simulation is used to generate forward interest rate paths.

The following table shows the estimated impact on MVE of 100 and 200 basis point shocks up and a 100 basis point shock down from current market implied forward rates.

TABLE 26: MARKET VALUE OF EQUITY SENSITIVITY AS OF MARCH 31, 2022

($ In Millions)	INCREASE (DECREASE) ESTIMATED IMPACT ON MARKET VALUE OF EQUITY
Increase in Interest Rates Above Market Implied Forward Rates
100 Basis Points	$	(329)
200 Basis Points	(859)
Decrease in Interest Rates Below Market Implied Forward Rates
100 Basis Points	$	(40)

The MVE simulations do not incorporate certain management actions that may be used to mitigate adverse effects of actual interest rate movements. For that reason and others, the estimated impacts do not reflect the likely actual results but serve as estimates of interest rate risk. MVE sensitivity is not comparable to actual results disclosed elsewhere or directly predictive of future values of other measures provided.

Foreign Currency Value-At-Risk (VaR) — Northern Trust measures daily the risk of loss associated with all non-U.S. currency positions using a VaR model and applying the historical simulation methodology. This statistical model provides

23

MARKET RISK MANAGEMENT (continued)

estimates, based on high confidence levels, of the potential loss in value that might be incurred if an adverse shift in non-U.S. currency exchange rates and interest rates were to occur over a small number of days. The model incorporates foreign currency and interest rate volatilities and correlations in price movements among the currencies. VaR is computed for each trading desk and for the global portfolio.

Northern Trust monitors several variations of the global foreign exchange (GFX) VaR measures to meet specific regulatory and internal management needs. Variations include different methodologies (historical simulation, Monte Carlo simulation and Taylor approximation), horizons of one day and ten days, confidence levels of 95% and 99%, subcomponent VaRs using only foreign exchange (FX) drivers and only interest rate (IR) drivers, and look-back periods of one year, two years, and four years. Those alternative measures provide management an array of corroborating metrics and alternative perspectives on Northern Trust’s market risks.

During the three months ended March 31, 2022 and December 31, 2021, Northern Trust did not incur an actual GFX trading loss in excess of the daily GFX VaR estimate.

The following table presents the levels of total regulatory VaR and its subcomponents for GFX in the periods indicated below, based on the historical simulation methodology, a 99% confidence level, a one-day horizon and equally-weighted volatility. The total VaR for GFX is typically less than the sum of its two subcomponents due to diversification benefits derived from the two subcomponents.

RECONCILIATION TO FULLY TAXABLE EQUIVALENT

The following table presents a reconciliation of interest income, net interest income, net interest margin, and total revenue prepared in accordance with GAAP to such measures on an FTE basis, which are non-GAAP financial measures. Net interest margin is calculated by dividing annualized net interest income by average interest-earning assets. Management believes this presentation provides a clearer indication of these financial measures for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on net income.

Notes to Consolidated Financial Statements (unaudited)

Note 1 – Basis of Presentation

The consolidated financial statements include the accounts of Northern Trust Corporation (Corporation) and its wholly-owned subsidiary, The Northern Trust Company (Bank), and various other wholly-owned subsidiaries of the Corporation and Bank. Throughout the notes to the consolidated financial statements, the term “Northern Trust” refers to the Corporation and its subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements, as of and for the periods ended March 31, 2022 and 2021, 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. The accounting and financial reporting policies of Northern Trust conform to U.S. generally accepted accounting principles (GAAP) and reporting practices prescribed for the banking industry. The consolidated statements of income include results of acquired subsidiaries from the dates of acquisition. Certain prior-period balances have been reclassified to conform with the current year’s presentation. During the first quarter of 2022, the Corporation changed the name of the Corporate & Institutional Services (C&IS) segment to “Asset Servicing.” Accordingly, the disclosures herein and all future disclosures regarding the Corporation’s reporting segments filed with, or furnished to, the SEC will refer to this segment as Asset Servicing. For a description of Northern Trust’s significant accounting policies, refer to Note 1 — Summary of Significant Accounting Policies included under Item 8. Financial Statements and Supplementary Data in the Annual Report on Form 10-K for the year ended December 31, 2021.

Note 2 – Recent Accounting Pronouncements

On January 1, 2022, Northern Trust adopted Accounting Standards Update (ASU) No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contract in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06). ASU 2020-06 simplifies the convertible instrument accounting framework through the elimination of the beneficial conversion and cash conversion accounting models used to account for convertible debt and convertible preferred stock. ASU 2020-06 also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions in Accounting Standards Codification 815—Derivatives and Hedging. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. Upon adoption of ASU 2020-06, there was no significant impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.

On January 1, 2022, Northern Trust adopted ASU No. 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” (ASU 2021-10). ASU 2021-10 requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy to other accounting guidance within Topic 958, Not-for-Profit Entities, or International Accounting Standards 20, Accounting for Government Grants and Disclosure of Government Assistance. Upon adoption of ASU 2021-10, there was no significant impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.

Note 3 – Fair Value Measurements

Fair Value Hierarchy. The following describes the hierarchy of valuation inputs (Levels 1, 2, and 3) used to measure fair value and the primary valuation methodologies used by Northern Trust for financial instruments measured at fair value on a recurring basis. Observable inputs reflect market data obtained from sources independent of the reporting entity; unobservable inputs reflect the entity’s own assumptions about how market participants would value an asset or liability based on the best information available. GAAP requires an entity measuring fair value to maximize the use of observable inputs and minimize the use of unobservable inputs and establishes a fair value hierarchy of inputs. Financial instruments are categorized within the hierarchy based on the lowest level input that is significant to their valuation. No transfers into or out of Level 3 occurred during the three months ended March 31, 2022 or the year ended December 31, 2021.

Level 1 — Quoted, active market prices for identical assets or liabilities.

Northern Trust’s Level 1 assets are comprised of available for sale (AFS) investments in U.S. Treasury securities.

Level 2 — Observable inputs other than Level 1 prices, such as quoted active market prices for similar assets or liabilities, quoted prices for identical or similar assets in inactive markets, and model-derived valuations in which all significant inputs are observable in active markets.

Northern Trust’s Level 2 assets include AFS and trading account debt securities, the fair values of which are determined predominantly by external pricing vendors. Prices received from vendors are compared to other vendor and third-party prices. If a security price obtained from a pricing vendor is determined to exceed predetermined tolerance levels that are assigned based on an asset type’s characteristics, the exception is researched and, if the price is not able to be validated, an alternate pricing

32

Notes to Consolidated Financial Statements (unaudited) (continued)

vendor is utilized, consistent with Northern Trust’s pricing source hierarchy. As of March 31, 2022, Northern Trust’s AFS debt securities portfolio included 2,576 Level 2 debt securities with an aggregate market value of $34.3 billion. All 2,576 debt securities were valued by external pricing vendors. As of December 31, 2021, Northern Trust’s AFS debt securities portfolio included 2,547 Level 2 debt securities with an aggregate market value of $35.6 billion. All 2,547 debt securities were valued by external pricing vendors. Trading account debt securities, which totaled $0.4 million and $0.3 million as of March 31, 2022 and December 31, 2021, respectively, were all valued using external pricing vendors.

Level 2 assets and liabilities also include derivative contracts which are valued internally using widely accepted income-based models that incorporate inputs readily observable in actively quoted markets and reflect the contractual terms of the contracts. Observable inputs include foreign exchange rates and interest rates for foreign exchange contracts; credit spreads, default probabilities, and recovery rates for credit default swap contracts; interest rates for interest rate swap contracts and forward contracts; and interest rates and volatility inputs for interest rate option contracts. Northern Trust evaluates the impact of counterparty credit risk and its own credit risk on the valuation of its derivative instruments. Factors considered include the likelihood of default by Northern Trust and its counterparties, the remaining maturities of the instruments, net exposures after giving effect to master netting arrangements or similar agreements, available collateral, and other credit enhancements in determining the appropriate fair value of derivative instruments. The resulting valuation adjustments have not been considered material.

Level 3 — Valuation techniques in which one or more significant inputs are unobservable in the marketplace.

Northern Trust’s Level 3 liabilities consist of swaps that Northern Trust entered into with the purchaser of 1.1 million and 1.0 million shares of Visa Inc. Class B common stock (Visa Class B common shares) previously held by Northern Trust and sold in June 2016 and 2015, respectively. Pursuant to the swaps, Northern Trust retains the risks associated with the ultimate conversion of the Visa Class B common shares into shares of Visa Inc. Class A common stock (Visa Class A common shares), such that the counterparty will be compensated for any dilutive adjustments to the conversion ratio and Northern Trust will be compensated for any anti-dilutive adjustments to the ratio. The swaps also require periodic payments from Northern Trust to the counterparty calculated by reference to the market price of Visa Class A common shares and a fixed rate of interest. The fair value of the swaps is determined using a discounted cash flow methodology. The significant unobservable inputs used in the fair value measurement are Northern Trust’s own assumptions about estimated changes in the conversion rate of the Visa Class B common shares into Visa Class A common shares, the date on which such conversion is expected to occur and the estimated growth rate of the Visa Class A common share price. See “Visa Class B Common Shares” under Note 21 — Commitments and Contingent Liabilities for further information.

Northern Trust believes its valuation methods for its assets and liabilities carried at fair value are appropriate; however, the use of different methodologies or assumptions, particularly as applied to Level 3 assets and liabilities, could have a material effect on the computation of their estimated fair values.

The following table presents the fair values of Northern Trust’s Level 3 liabilities as of March 31, 2022 and December 31, 2021, as well as the valuation techniques, significant unobservable inputs, and quantitative information used to develop significant unobservable inputs for such liabilities as of such dates.

(1) (Gains) losses are recorded in Other Operating Income on the consolidated statements of income.

Carrying values of assets and liabilities that are not measured at fair value on a recurring basis may be adjusted to fair value in periods subsequent to their initial recognition, for example, to record an impairment of an asset. GAAP requires entities to separately disclose these subsequent fair value measurements and to classify them under the fair value hierarchy.

Assets measured at fair value on a nonrecurring basis at March 31, 2022 and December 31, 2021, all of which were categorized as Level 3 under the fair value hierarchy, were comprised of nonaccrual loans whose values were based on real estate and other available collateral, and of other real estate owned (OREO) properties.

Fair values of real estate loan collateral were estimated using a market approach typically supported by third-party valuations and property-specific fees and taxes. The fair values of real estate loan collateral were subject to adjustments to reflect management’s judgment as to realizable value and consisted of discount factors ranging from 15.0% to 20.0% with a weighted average based on fair values of 16.3% and 15.4% as of March 31, 2022 and December 31, 2021, respectively. Other loan

35

Notes to Consolidated Financial Statements (unaudited) (continued)

collateral, which typically consists of accounts receivable, inventory and equipment, is valued using a market approach adjusted for asset-specific characteristics and in limited instances third-party valuations are used. OREO assets are carried at the lower of cost or fair value less estimated costs to sell, with fair value typically based on third-party appraisals.

Collateral-based nonaccrual loans that have been adjusted to fair value totaled $13.3 million and $15.0 million at March 31, 2022 and December 31, 2021, respectively.

The following table presents the fair values of Northern Trust’s Level 3 assets that were measured at fair value on a nonrecurring basis as of March 31, 2022 and December 31, 2021, as well as the valuation technique, significant unobservable inputs and quantitative information used to develop the significant unobservable inputs for such assets as of such dates.

As of March 31, 2022, 2,196 AFS debt securities with a combined fair value of $26.0 billion were in an unrealized loss position, with their unrealized losses totaling $1,157.7 million. As of March 31, 2022, unrealized losses related to AFS debt securities of $475.9 million and $256.6 million related to government-sponsored agency securities and obligations of states and political subdivisions, respectively, are primarily attributable to changes in market interest rates and credit spreads since their purchase.

As of December 31, 2021, 1,233 AFS debt securities with a combined fair value of $18.7 billion were in an unrealized loss position, with their unrealized losses totaling $248.6 million. As of December 31, 2021, unrealized losses related to AFS debt securities of $110.2 million related to government-sponsored agency securities, which are primarily attributable to changes in market interest rates and credit spreads since their purchase.

12% and 14% of the AFS corporate debt securities portfolio were backed by guarantees provided by U.S. and non-U.S. governmental entities as of March 31, 2022 and December 31, 2021, respectively. The remaining unrealized losses on Northern Trust’s AFS debt securities portfolio as of March 31, 2022 and December 31, 2021 are attributable to changes in overall market interest rates or credit spreads.

As of March 31, 2022, Northern Trust did not intend to sell any AFS debt securities in an unrealized loss position and it was more likely than not that Northern Trust would not be required to sell any such investment before the recovery of its amortized cost basis, which may be maturity.

AFS debt securities impairment reviews are conducted quarterly to identify and evaluate securities that have indications of possible credit losses. A determination as to whether a security’s decline in market value is related to credit impairment takes into consideration numerous factors and the relative significance of any single factor can vary by security. Factors Northern Trust considers in determining whether impairment is credit-related include, but are not limited to, the severity of the impairment; the cause of the impairment and the financial condition and near-term prospects of the issuer; activity in the market of the issuer, which may indicate adverse credit conditions; Northern Trust’s intent regarding the sale of the security as of the balance sheet date; and the likelihood that Northern Trust will not be required to sell the security for a period of time sufficient to allow for the recovery of the security’s amortized cost basis. For each security meeting the requirements of Northern Trust’s internal screening process, an extensive review is conducted to determine if a credit loss has occurred.

There was a $0.4 million provision for credit losses for corporate debt AFS securities for the three months ended March 31, 2022, while there was no provision for credit losses for corporate debt AFS securities for the three months ended March 31, 2021. There was a $0.4 million allowance for credit losses for corporate debt AFS securities as of March 31, 2022 and no allowance for credit losses for corporate debt AFS securities as of December 31, 2021. The process for identifying credit losses for corporate debt AFS securities is based on the best estimate of cash flows to be collected from the security, discounted using the security’s effective interest rate. If the present value of the expected cash flows is found to be less than the current amortized cost of the security, an allowance for credit losses is generally recorded equal to the difference between the two amounts, limited to the amount the amortized cost basis exceeds the fair value of the security. For additional information, please refer to Note 7 — Allowance for Credit Losses.

Notes to Consolidated Financial Statements (unaudited) (continued)

HTM debt securities consist of securities that management intends to, and Northern Trust has the ability to, hold until maturity. During the three months ended March 31, 2022 and 2021, no securities were transferred from AFS to HTM. Upon transfer of a debt security from the AFS to HTM classification, the amortized cost is reset to fair value. Any net unrealized gain or loss at the date of transfer will remain in Accumulated Other Comprehensive Income (Loss) (AOCI) and be amortized into net interest income over the remaining life of the securities using the effective interest method. The amortization of amounts retained in AOCI will offset the effect on interest income of the amortization of the premium or discount resulting from transferring the securities at fair value.

Credit Quality Indicators. The following table provides the amortized cost of HTM debt securities by credit rating.

Credit quality indicators are metrics that provide information regarding the relative credit risk of debt securities. Northern Trust maintains a high quality debt securities portfolio, with 92% and 94% of the HTM portfolio at both March 31, 2022 and December 31, 2021, respectively, comprised of securities rated A or higher. The remaining HTM debt securities portfolio was comprised of 2% and 1% rated BBB at March 31, 2022 and December 31, 2021, respectively, and 6% and 5% not rated by Moody’s, S&P Global, or Fitch Ratings at March 31, 2022 and December 31, 2021, respectively. Securities not explicitly rated were grouped where possible under the credit rating of the issuer of the security.

Investment Security Gains and Losses. There were no sales of debt securities during the three months ended March 31, 2022 and 2021. There were no net investment security (losses) gains for the three months ended March 31, 2022 and 2021.

Note 5 – Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase are accounted for as collateralized financings and recorded at the amounts at which the securities were sold plus accrued interest. To minimize any potential credit risk associated with these transactions, the fair value of the securities sold is monitored, limits are set on exposure with counterparties, and the financial condition of counterparties is regularly assessed. Securities sold under agreements to repurchase are either directly held by, or pledged to the counterparty until the repurchase.

Residential real estate loans consist of traditional first lien mortgages and equity credit lines that generally require a loan-to-collateral value of no more than 65% to 80% at inception. Northern Trust’s equity credit line products generally have draw periods of up to 10 years and a balloon payment of any outstanding balance is due at maturity. Payments are interest-only with variable interest rates. Northern Trust does not offer equity credit lines that include an option to convert the outstanding balance to an amortizing payment loan. As of March 31, 2022 and December 31, 2021, equity credit lines totaled $233.5 million and $258.2 million, respectively, and equity credit lines for which first liens were held by Northern Trust represented 97% of the total equity credit lines as of both March 31, 2022 and December 31, 2021.

Included within the non-U.S., commercial-other and personal-other classes are short-duration advances primarily related to the processing of custodied client investments, totaling $1.9 billion at March 31, 2022 and $1.6 billion at December 31, 2021, respectively. Demand deposit overdrafts reclassified as loan balances totaled $9.7 million and $8.0 million at March 31, 2022 and December 31, 2021, respectively. Loans classified as held for sale, which totaled $10.8 million and $12.3 million at March 31, 2022 and December 31, 2021, respectively, related to the decision to exit a non-strategic loan portfolio. Loans classified as held for sale are recorded at the lower of cost or fair value.

As of March 31, 2022 and December 31, 2021, there were no leases classified as held for sale.

Paycheck Protection Program. In response to the COVID-19 pandemic, Northern Trust became a lender under the Paycheck Protection Program, as amended (PPP), which was created by the Coronavirus Aid, Relief, and Economic Security (CARES) Act and is administered by the U.S. Small Business Administration (SBA). Loans issued under the PPP are funded by Northern Trust directly to participating borrowers. The PPP loans are guaranteed by the SBA and borrowers are eligible to apply for PPP loan forgiveness for up to the full principal amount and accrued interest of the PPP loan.

42

Notes to Consolidated Financial Statements (unaudited) (continued)

To the extent a borrower uses PPP loan proceeds to cover eligible costs and has met all other SBA loan forgiveness requirements, the SBA will determine loan forgiveness under the CARES Act and will pay to Northern Trust the eligible PPP loan forgiven amount, which will be credited to the borrower’s loan to repay or pay down the PPP loan. The SBA forgiveness portal opened on August 10, 2020 and Northern Trust’s vendor portal opened on September 11, 2020 to begin processing the PPP loan forgiveness applications. When Northern Trust submits forgiveness applications to the SBA, the SBA has at least 90 days to respond as to the approval or denial of such application. 143 and 1,301 loans were forgiven through the PPP loan forgiveness process which resulted in $39.2 million and $231.5 million of loan principal and interest being forgiven during the three months ended March 31, 2022 and the year ended December 31, 2021, respectively.

As of March 31, 2022, Northern Trust had 73 outstanding loans totaling $16.3 million under the PPP in its commercial and institutional portfolio with an average loan balance of $0.2 million.

Northern Trust accounts for loans originated under the PPP as loan receivables in accordance with Accounting Standards Codification (ASC) 310 and recognizes such loans at the principal amount less the net amount of loan origination fees. PPP loans are reported in Total Loans and Leases on the consolidated balance sheets.

The SBA provides a 100% guarantee on PPP loans covering principal and interest. Northern Trust considers the risk mitigating effects of these guarantees, and accounts for them as a credit enhancement embedded in the contract. As a result, no allowance for credit losses is measured for Northern Trust’s exposure under the PPP.

Credit Quality Indicators. Credit quality indicators are statistics, measurements or other metrics that provide information regarding the relative credit risk of loans and leases. Northern Trust utilizes a variety of credit quality indicators to assess the credit risk of loans and leases at the segment, class, and individual credit exposure levels.

As part of its credit process, Northern Trust utilizes an internal borrower risk rating system to support identification, approval, and monitoring of credit risk. Borrower risk ratings are used in credit underwriting and management reporting. Risk ratings are used for ranking the credit risk of borrowers and the probability of their default. Each borrower is rated using one of a number of ratings models, which consider both quantitative and qualitative factors. The ratings models vary among classes of loans and leases in order to capture the unique risk characteristics inherent within each particular type of credit exposure. Provided below are the more significant performance indicator attributes considered within Northern Trust’s borrower rating models, by loan and lease class.

•Commercial and Institutional: leverage, profit margin, liquidity, asset size and capital levels;

•Commercial Real Estate: debt service coverage, loan-to-value ratio, leasing status and guarantor support;

•Lease Financing and Commercial-Other: leverage, profit margin, liquidity, asset size and capital levels;

•Non-U.S.: leverage, profit margin, liquidity, return on assets and capital levels;

•Residential Real Estate: payment history, credit bureau scores and loan-to-value ratio;

•Private Client: cash-flow-to-debt and net worth ratios, leverage and liquidity; and

•Personal-Other: cash-flow-to-debt and net worth ratios.

While the criteria vary by model, the objective is for the borrower ratings to be consistent in both the measurement and ranking of risk. Each model is calibrated to a master rating scale to support this consistency. Ratings for borrowers not in default range from “1” for the strongest credits to “7” for the weakest non-defaulted credits. Ratings of “8” or “9” are used for defaulted borrowers. Borrower risk ratings are monitored and are revised when events or circumstances indicate a change is required. Risk ratings are generally validated at least annually.

Loan and lease segment and class balances as of March 31, 2022 and December 31, 2021 are provided in the following table, segregated by borrower ratings into “1 to 3,” “4 to 5” and “6 to 9” (watch list and nonaccrual status) categories by year of origination at amortized cost basis. Loans that are held for investment are reported at the principal amount outstanding, net of unearned income.

Notes to Consolidated Financial Statements (unaudited) (continued)

Loans and leases in the “1 to 3” category are expected to exhibit minimal to modest probabilities of default and are characterized by borrowers having the strongest financial qualities, including above average financial flexibility, cash flows and capital levels. Borrowers assigned these ratings are anticipated to experience very little to moderate financial pressure in adverse down-cycle scenarios. As a result of these characteristics, borrowers within this category exhibit a minimal to modest likelihood of loss.

Loans and leases in the “4 to 5” category are expected to exhibit moderate to acceptable probabilities of default and are characterized by borrowers with less financial flexibility than those in the “1 to 3” category. Cash flows and capital levels are generally sufficient to allow for borrowers to meet current requirements, but have fewer financial resources to manage through economic downturns. As a result of these characteristics, borrowers within this category exhibit a moderate likelihood of loss.

Loans and leases in the watch list category have elevated credit risk profiles that are monitored through internal watch lists, and consist of credits with borrower ratings of “6 to 9.” These credits, which include all nonaccrual credits, are expected to exhibit minimally acceptable probabilities of default, elevated risk of default, or are currently in default. Borrowers associated with these risk profiles that are not currently in default have limited financial flexibility. Cash flows and capital levels range from acceptable to potentially insufficient to meet current requirements, particularly in adverse down cycle scenarios. As a result of these characteristics, borrowers in this category exhibit an elevated to probable likelihood of loss.

Past Due Status. Past due status is based on the length of time from the contractual due date a principal or interest payment has been past due. For disclosure purposes, loans and leases that are 29 days past due or less are reported as current.

The following table provides balances and delinquency status of accrual and nonaccrual loans and leases by segment and class, as well as the other real estate owned and nonaccrual asset balances, as of March 31, 2022 and December 31, 2021.

Interest income that would have been recorded for nonaccrual loans and leases in accordance with their original terms was $1.1 million and $0.9 million for the three months ended March 31, 2022 and 2021, respectively.

Collateral Dependent Financial Assets. A financial asset is collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. Most of Northern Trust’s collateral dependent credit exposure relates to its residential real estate portfolio for which the collateral is usually the underlying real estate property. For collateral dependent financial assets, it is Northern Trust’s policy to reserve or charge-off the difference between the amortized cost basis of the loan and the value of the collateral. The collateral dependent financial asset balance as of March 31, 2022 was immaterial to Northern Trust’s financial statements.

Recognition of Income. Interest income on loans and leases is recorded on an accrual basis unless, in the opinion of management, there is a question as to the ability of the debtor to meet the terms of the loan agreement, or interest or principal is more than 90 days contractually past due and the loan is not well-secured and in the process of collection. Loans meeting such criteria are classified as nonaccrual and interest income is recorded on a cash basis. At the time a loan is determined to be nonaccrual, interest accrued but not collected is reversed against interest income in the current period. Interest collected on nonaccrual loans is applied to principal unless, in the opinion of management, collectability of principal is not in doubt. Management’s assessment of the indicators of loan and lease collectability, and its policies relative to the recognition of interest income, including the suspension and subsequent resumption of income recognition, do not meaningfully vary between loan and lease classes. Nonaccrual loans are returned to accrual status when factors indicating doubtful collectability no longer exist. Factors considered in returning a loan to accrual status are consistent across all classes of loans and leases and, in accordance with regulatory guidance, relate primarily to expected payment performance. Loans are eligible to be returned to accrual status when: (i) no principal or interest that is due is unpaid and repayment of the remaining contractual principal and interest is expected or (ii) the loan has otherwise become well-secured (possessing realizable value sufficient to discharge the debt, including accrued interest, in full) and is in the process of collection (through action reasonably expected to result in debt repayment or restoration to a current status in the near future). A loan that has not been brought fully current may be restored to accrual status provided there has been a sustained period of repayment performance (generally a minimum of six payment periods) by the borrower in accordance with the contractual terms, and Northern Trust is reasonably assured of repayment within a reasonable period of time. Additionally, a loan that has been formally restructured so as to be reasonably assured of repayment and performance according to its modified terms may be returned to accrual status, provided there was a well-documented credit evaluation of the borrower’s financial condition and prospects of repayment under the revised terms and there has been a sustained period of repayment performance (generally a minimum of six payment periods) under the revised terms.

Nonaccrual Loans and Troubled Debt Restructurings (TDRs). A loan that has been modified as a concession by Northern Trust or a bankruptcy court resulting from the debtor’s financial difficulties is referred to as a troubled debt restructuring (TDR). All TDRs are reported starting in the calendar year of their restructuring. In subsequent years, a TDR may cease being reported if the loan was modified at a market rate and has performed according to the modified terms for at least six payment

47

Notes to Consolidated Financial Statements (unaudited) (continued)

periods. A loan that has been modified at a below market rate will return to accrual status if it satisfies the six-payment-period performance requirement.

The expected credit loss is measured based upon the present value of expected future cash flows, discounted at the effective interest rate based on the original contractual rate. If a loan’s contractual interest rate varies based on subsequent changes in an independent factor, such as an index or rate, the loan’s effective interest rate is calculated based on the factor as it changes over the life of the loan. Northern Trust elected not to project changes in the factor for purposes of estimating expected future cash flows. Further, Northern Trust elected not to adjust the effective interest rate for prepayments. If the loan is collateral dependent, the expected loss is measured based on the fair value of the collateral at the reporting date.

If the loan valuation is less than the recorded value of the loan, either an allowance is established or a charge-off is recorded for the difference. Smaller balance (individually less than $1 million) homogeneous loans are collectively evaluated. Northern Trust’s accounting policies for material nonaccrual loans is consistent across all classes of loans and leases.

All loans and leases with TDR modifications are evaluated for additional expected credit losses. The nature and extent of further deterioration in credit quality, including a subsequent default, is considered in the determination of an appropriate level of allowance for credit losses.

Included within nonaccrual loans were $46.1 million and $76.7 million of nonaccrual TDRs, and $18.3 million and $16.5 million of accrual TDRs as of March 31, 2022 and December 31, 2021, respectively.

There were $0.2 million of aggregate undrawn loan commitments and standby letters of credit at both March 31, 2022 and December 31, 2021 issued to borrowers with TDR modifications of loans.

The following table provides, by segment and class, the number of TDR modifications of loans and leases during the three months ended March 31, 2022 and 2021, and the recorded investments and unpaid principal balances as of March 31, 2022 and 2021.

TDR modifications involve extensions of term, deferrals of principal, interest rate concessions, and other modifications. Other modifications typically reflect other nonstandard terms which Northern Trust would not offer in non-troubled situations.

During the three months ended March 31, 2022, the TDR loan modifications within residential real estate were deferred principal, interest rate concession, and an extension of term. During the three months ended March 31, 2022, the TDR modification of loans within commercial and institutional was an other modification.

48

Notes to Consolidated Financial Statements (unaudited) (continued)

During the three months ended March 31, 2021, the TDR modification of loans within commercial and institutional, residential real estate and commercial real estate was deferred principal.

There were no residential real estate loan TDR modifications during the twelve months ended December 31, 2021, which subsequently had a payment default during the three months ended March 31, 2022.

There was one residential real estate loan TDR modification during the twelve months ended December 31, 2020, which subsequently had a payment default during the three months ended March 31, 2021. The total recorded investment for this loan was approximately $5.5 million and the unpaid principal balance for this loan was approximately $5.5 million.

Northern Trust may obtain physical possession of real estate via foreclosure on an in-substance repossession. As of March 31, 2022, Northern Trust held foreclosed real estate properties with a carrying value of $0.2 million as a result of obtaining physical possession. In addition, as of March 31, 2022, Northern Trust had loans with a carrying value of $1.7 million for which formal foreclosure proceedings were in process.

TDR Relief — COVID-19. Due to the economic environment arising from the COVID-19 pandemic, there have been two forms of relief provided for classifying loans as TDRs: the Interagency Guidance (as defined below) and the CARES Act.

Various banking regulators, including the Board of Governors of the Federal Reserve (Federal Reserve Board), the Federal Deposit Insurance Corporation (FDIC), the National Credit Union Administration, the Office of the Comptroller of the Currency, and the Consumer Financial Protection Bureau, issued guidance in the April 7, 2020 Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (revised) on loan modification treatment (Interagency Guidance) pursuant to which financial institutions can apply ASC 310-40 Receivables – Troubled Debt Restructurings by Creditors. In accordance with the Interagency Guidance, a loan modification is not considered a TDR if: (a) the modification is related to COVID-19; (b) the borrower had been current (not more than 29 days past due) when the modification program was implemented; (c) and the modification includes payment deferrals for not more than 6 months.

Under section 4013 of the CARES Act, relief provided to lenders exempting certain loan modifications which would otherwise be classified as TDRs from such classification applies for loans that were not more than 30 days past due as of December 31, 2019. The TDR relief under the CARES Act applies to COVID-19-related modifications that were made from March 1, 2020 until the earlier of (a) January 1, 2022 or (b) 60 days from the date the COVID-19 national emergency officially ends.

Financial institutions may account for eligible loan modifications under the Interagency Guidance and/or the CARES Act. Northern Trust elected to apply both the CARES Act and the Interagency Guidance, as applicable, in providing borrowers with loan modification relief in response to the COVID-19 pandemic. All other types of modifications which do not meet the CARES Act or Interagency Guidance requirements continue to be governed by existing regulations and accounting policies.

The following provides the number of total COVID-19-related loan modifications including the loan volume and deferred principal and interest balances as of March 31, 2022 and December 31, 2021, for which Northern Trust applied an exemption from TDR classification that are in active deferral (loans currently in the deferral period) or completed deferral (loans that returned to their regular payment schedule). As of March 31, 2022, there were no COVID-19-related loan modifications in active deferral status. As of December 31, 2021, there were three residential real estate COVID-19-related loan modifications in active deferral status which totaled $2.0 million, with immaterial deferred principal and interest.

Northern Trust continues to accrue and recognize interest income during the loan deferral period, and hence has not moved these loans to nonaccrual or reported them as past due. Further, these loan balances continue to be assessed on a collective basis for purposes of measuring an allowance for expected credit losses. While these loans are under the COVID-19 loan modification program, this may delay the recognition of nonaccruals and charge-offs. Loans which have exited the COVID-19 loan modification program may be placed on nonaccrual status or charged-off if borrowers were unable to resume their regular payment schedule.

During the period ended March 31, 2022, 38 loans with an aggregate principal amount of $112.9 million that had been granted payment deferrals were paid off. As of March 31, 2022, less than 3% of loans that had been granted payment deferrals were either past due or in nonaccrual status.

Note 7 – Allowance for Credit Losses

Allowance and Provision for Credit Losses. The allowance for credit losses—which represents management’s best estimate of lifetime expected credit losses related to various portfolios subject to credit risk, off-balance-sheet credit exposures, and specific borrower relationships—is determined by management through a disciplined credit review process. Northern Trust measures expected credit losses of financial assets with similar risk characteristics on a collective basis. A financial asset is measured individually if it does not share similar risk characteristics with other financial assets and the related allowance is determined through an individual evaluation.

Management’s estimates utilized in establishing an appropriate level of allowance for credit losses are not dependent on any single assumption. In determining an appropriate allowance level, management evaluates numerous variables, many of which are interrelated or dependent on other assumptions and estimates, and takes into consideration past events, current conditions and reasonable and supportable forecasts.

The results of the credit reserve estimation methodology are reviewed quarterly by Northern Trust’s Credit Loss Reserve Committee, which receives input from Credit Risk Management, Treasury, Corporate Finance, the Economic Research group, and each of Northern Trust’s business units. The Credit Loss Reserve Committee determines the probability weights applied to each forecast approved by Northern Trust’s Macroeconomic Scenario Development Committee, and also reviews and approves qualitative adjustments to the collective allowance in line with Northern Trust’s qualitative adjustment framework.

The portion of the allowance assigned to loans and leases, HTM debt securities, and other financial assets is presented as a contra asset in Allowance for Credit Losses on the consolidated balance sheets. The portion of the allowance assigned to undrawn loan commitments and standby letters of credit is reported in Other Liabilities on the consolidated balance sheets. For credit exposure and the associated allowance related to fee receivables, please refer to Note 14 — Revenue from Contracts with Clients. For information related to the allowance for AFS debt securities, please refer to Note 4 — Securities. For all other financial assets recognized at amortized cost, which include Cash and Due from Banks, Other Central Bank Deposits, Interest Bearing Deposits with Banks, and Other Assets, please refer to the Allowance for Other Financial Assets section within this footnote.

The Provision for Credit Losses on the consolidated statements of income represents the change in the Allowance for Credit Losses on the consolidated balance sheets and is the charge to current period earnings. It represents the amount needed to maintain the Allowance for Credit Losses on the consolidated balance sheets at an appropriate level to absorb lifetime expected credit losses related to financial assets in scope. Actual losses may vary from current estimates and the amount of the Provision for Credit Losses may be either greater or less than actual net charge-offs.

There was a $2.0 million provision in the current quarter, as compared to a $30.0 million release of credit reserves in the prior-year quarter. The provision for credit losses, excluding available for sale debt securities, was a provision of $1.6 million in the current quarter. There were net recoveries of $3.2 million during the three months ended March 31, 2022, as compared to net recoveries of $0.9 million for the three months ended March 31, 2021. For further detail, please see the Allowance for the Loan and Lease Portfolio and the Allowance for Held to Maturity Debt Securities Portfolio sections below.

Notes to Consolidated Financial Statements (unaudited) (continued)

Forecasting and Reversion. Estimating expected lifetime credit losses requires the consideration of the effect of future economic conditions. Northern Trust employs multiple scenarios over a reasonable and supportable period (currently two years) to project future conditions. Management determines the probability weights assigned to each scenario at each quarter-end. Key variables determined to be relevant for projecting credit losses on the portfolios in scope include macroeconomic factors, such as corporate profits, unemployment, and real estate price indices, as well as financial market factors such as equity prices, volatility, and credit spreads. For periods beyond the reasonable and supportable period, Northern Trust reverts to its own historical loss experiences on a straight-line basis over four quarters. For the current quarter, the primary forecast, consistent with Northern Trust’s economic outlook publications, continues to reflect an economy recovering from the challenges of COVID-19 and returning to normal. The positive effects of steady growth and falling unemployment rates are partially diminished by the impact of higher inflation, volatility, interest rates and geopolitical events. An alternative scenario is also considered, which reflects a recession that incorporates the experiences of a wider set of historical economic cycles.

Contractual Term. Northern Trust estimates expected credit losses over the contractual term of the financial assets adjusted for prepayments, unless prepayments are not relevant to specific portfolios or sub-portfolios. Extension and renewal options are typically not considered since it is not Northern Trust’s practice to enter into arrangements where the borrower has the unconditional option to renew, or a conditional extension option whereby the conditions are beyond Northern Trust’s control.

Allowance for the Loan and Lease Portfolio. The following table provides information regarding changes in the total allowance for credit losses, including undrawn loan commitments and standby letters of credit, by segment during the three months ended March 31, 2022 and 2021.

The decrease to the allowance for loans and leases of $2.1 million for the three months ended March 31, 2022 was primarily due to a decrease in the reserve evaluated on a collective basis, driven by continued improvements in credit quality, mainly within the commercial real estate portfolio, and partially offset by the impact of worsening projected economic conditions. The decrease in the collective basis reserve was diminished by an increase to the reserve evaluated on an individual basis for two individual commercial borrowers. The increase to the allowance for undrawn loan commitments and standby letters of credit of $3.4 million for the three months ended March 31, 2022 was primarily due to worsening projected economic conditions and an increase in potential exposure.

Allowance Related to Credit Exposure Evaluated on a Collective Basis. Expected credit losses are measured on a collective basis as long as the financial assets included in the respective pool share similar risk characteristics. If financial assets are deemed to not share similar risk characteristics, an individual assessment is warranted.

The allowance estimation methodology for the collective assessment is primarily based on internally developed loss data specific to the Northern Trust financial asset portfolio from a historical observation period that includes both expansionary and

52

Notes to Consolidated Financial Statements (unaudited) (continued)

recessionary periods. The estimation methodology and the related qualitative adjustment framework segregate the loan and lease portfolio into homogenous segments based on similar risk characteristics or risk monitoring methods.

Northern Trust utilizes a quantitative probability of default/loss given default approach for the calculation of its credit allowance on a collective basis. For each of the different parameters, specific credit models for the individual loan segments were developed. For each segment, the probability of default and the loss given default are applied to the exposure at default for each projected quarter to determine the quantitative component of the allowance. The quantitative allowance is then reviewed within the qualitative adjustment framework, through which management applies judgment by assessing internal risk factors, potential limitations in the quantitative methodology, and environmental factors that are not fully contemplated in the forecast to compute an adjustment to the quantitative allowance for each segment of the loan portfolio.

Allowance Related to Credit Exposure Evaluated on an Individual Basis. The allowance is determined through an individual evaluation of loans, leases, and lending-related commitments that have defaulted, generally those with Borrower Ratings of 8 and 9, that is based on expected future cash flows, the value of collateral, and other factors that may impact the borrower’s ability to pay. For defaulted loans for which the amount of allowance, if any, is determined based on the value of the underlying real estate collateral, third-party appraisals are typically obtained and utilized by management. These appraisals are generally less than twelve months old and are subject to adjustments to reflect management’s judgment as to the realizable value of the collateral.

The following table provides information regarding the recorded investments in loans and leases and the allowance for credit losses for loans and leases and undrawn loan commitments and standby letters of credit by segment as of March 31, 2022 and December 31, 2021.

Northern Trust analyzes its exposure to credit losses from both on-balance-sheet and off-balance-sheet activity using a consistent methodology for the quantitative framework as well as the qualitative framework. For purposes of estimating the allowance for credit losses for undrawn loan commitments and standby letters of credit, the exposure at default includes an estimated drawdown of unused credit based on credit utilization factors, resulting in a proportionate amount of expected credit losses.

HTM debt securities classified as U.S. government, government sponsored agency, and certain securities classified as obligations of states and political subdivisions are considered to be guarantees of the U.S. government or an agency of the U.S. government and therefore an allowance for credit losses is not estimated for such investments as the expected probability of non-payment of the amortized cost basis is zero.

HTM debt securities classified as other asset-backed represent pools of underlying receivables from which the cash flows are used to pay the bonds that vary in seniority. Utilizing a qualitative estimation approach, the allowance for other asset-backed securities is assessed by evaluating underlying pool performance based on delinquency rates and available credit support.

HTM debt securities classified as other relates to investments purchased by Northern Trust to fulfill its obligations under the Community Reinvestment Act (CRA). Northern Trust fulfills its obligations under the CRA by making qualified investments for purposes of supporting institutions and programs that benefit low-to-moderate income communities within Northern Trust’s market area. The allowance for CRA investments is assessed using a qualitative estimation approach primarily based on internal historical performance experience and default history of the underlying CRA portfolios to determine a quantitative component of the allowance.

The allowance estimation methodology for all other HTM debt securities is developed using a combination of external and internal data. The estimation methodology groups securities with shared characteristics for which the probability of default and the loss given default are applied to the total exposure at default to determine a quantitative component of the allowance.

The increase in the allowance attributable to HTM debt securities was due to an increase in the reserve evaluated on a collective basis driven by model enhancements and related macroeconomic factors.

Allowance for Other Financial Assets. The allowance for Other Financial Assets consists of the allowance for Due from Banks, Other Central Bank Deposits, Interest Bearing Deposits with Banks, and Other Assets. The Other Assets category includes other miscellaneous credit exposures reported in Other Assets on the consolidated balance sheets. The allowance estimation methodology for Other Financial Assets primarily utilizes a similar approach as used for the HTM debt securities portfolio. It consists of a combination of externally and internally developed loss data, adjusted for the appropriate contractual term. Northern Trust’s portfolio of Other Financial Assets is composed mostly of institutions within the “1 to 3” internal borrower rating category and is expected to exhibit minimal to modest likelihood of loss. The allowance for credit losses related to Other Financial Assets was $1.1 million and $1.0 million as of March 31, 2022 and December 31, 2021, respectively.

Accrued Interest. Accrued interest balances are reported within Other Assets on the consolidated balance sheets. Northern Trust elected not to measure an allowance for credit losses for accrued interest receivables related to its loan and securities portfolio as its policy is to write-off uncollectible accrued interest receivable balances in a timely manner. Accrued interest is written off by reversing interest income during the quarter the financial asset is moved from an accrual to a nonaccrual status.

The following table provides the amount of accrued interest excluded from the amortized cost basis of the following portfolios.

Note 10 – Reporting Segments

During the first quarter of 2022, the Corporation changed the name of its C&IS segment to “Asset Servicing.” Accordingly, the disclosures herein and all future disclosures regarding the Corporation’s reporting segments filed with, or furnished to, the SEC will refer to this segment as Asset Servicing. This change has not had, and is not expected in the future to have, any impact upon the methodology by which the Corporation allocates revenue and expense to each of its reporting segments.

Northern Trust is organized around its two client-focused reporting segments: Asset Servicing and Wealth Management. Asset management and related services are provided to Asset Servicing and Wealth Management clients primarily by the Asset Management business. The revenue and expenses of Asset Management and certain other support functions are allocated fully to Asset Servicing and Wealth Management.

Reporting segment financial information, presented on an internal management reporting basis, is determined by accounting systems used to allocate revenue and expense to each segment, and incorporates processes for allocating assets, liabilities, equity and the applicable interest income and expense utilizing a funds transfer pricing (FTP) methodology. Under the methodology, assets and liabilities receive a funding charge or credit that considers interest rate risk, liquidity risk, and other product characteristics on an instrument level. Additionally, segment information is presented on an FTE basis as management

56

Notes to Consolidated Financial Statements (unaudited) (continued)

believes an FTE presentation provides a clearer indication of net interest income. The adjustment to an FTE basis has no impact on Net Income.

Revenues, expenses and average assets are allocated to Asset Servicing and Wealth Management, with the exception of non-recurring activities such as certain costs associated with acquisitions, divestitures, litigation, restructuring, and tax adjustments not directly attributable to a specific reporting segment.

Reporting segment results are subject to reclassification when organizational changes are made. The results are also subject to refinements in revenue and expense allocation methodologies, which are typically reflected on a prospective basis.

The following table presents the earnings contributions and average assets of Northern Trust’s reporting segments for the three month periods ended March 31, 2022 and 2021.

Note 14 – Revenue from Contracts with Clients

Trust, Investment, and Other Servicing Fees. Custody and Fund Administration income is comprised of revenues received from our core asset servicing business for providing custody, fund administration, and middle-office-related services, primarily to Asset Servicing clients. Investment Management and Advisory income contains revenue received from providing asset management and related services to Wealth Management and Asset Servicing clients and to Northern Trust sponsored funds. Securities Lending income represents revenues generated from securities lending arrangements that Northern Trust enters into as agent, mainly with Asset Servicing clients. Other income largely consists of revenues received from providing employee benefit, investment risk and analytic and other services to Asset Servicing and Wealth Management clients.

Other Noninterest Income. Treasury management income represents revenues received from providing cash and liquidity management services to Asset Servicing and Wealth Management clients. The portion of Security Commissions and Trading Income that relates to revenue from contracts with clients is primarily comprised of commissions earned from providing securities brokerage services to Wealth Management and Asset Servicing clients. The portion of Other Operating Income that relates to revenue from contracts with clients is mainly comprised of service fees for banking-related services provided to Wealth Management and Asset Servicing clients.

Performance Obligations. Clients are typically charged monthly or quarterly in arrears based on the fee arrangement agreed to with each client; payment terms will vary depending on the client and services offered.

Substantially all revenues generated from contracts with clients for asset servicing, asset management, securities lending, treasury management and banking-related services are recognized on an accrual basis, over the period in which services are provided. The nature of Northern Trust’s performance obligations is to provide a series of distinct services in which the customer simultaneously receives and consumes the benefits of the promised services as they are performed. Fee arrangements are mainly comprised of variable amounts based on market value of client assets managed and serviced, transaction volumes, number of accounts, and securities lending volume and spreads. Revenue is recognized using the output method in an amount that reflects the consideration to which Northern Trust expects to be entitled in exchange for providing each month or quarter of service. For contracts with multiple performance obligations, revenue is allocated to each performance obligation based on the price agreed to with the client, representing its relative standalone selling price.

Security brokerage revenue is primarily represented by securities commissions received in exchange of providing trade execution related services. Control is transferred at a point in time, on the trade date of the transaction, and fees are typically variable based on transaction volumes and security types.

Northern Trust’s contracts with its clients are typically open-ended arrangements and are therefore considered to have an original duration of less than one year. Northern Trust has elected the practical expedient to not disclose the value of remaining performance obligations for contracts with an original expected duration of one year or less.

The following table presents revenues disaggregated by major revenue source.

Note 16 – Other Operating Income

The components of Other Operating Income were as follows:

Loan Service Fees	$	16.7	$	15.4
Banking Service Fees	12.7		12.7
Other Income	11.7		26.8
Total Other Operating Income	$	41.1	$	54.9

Other Operating Income decreased compared to the prior-year quarter, primarily driven by the accounting reclassification and lower miscellaneous income. The lower miscellaneous income was primarily associated with a market value decrease in the supplemental compensation plans, which also resulted in a related decrease in supplemental compensation plan expense reported in Other Operating Expense.

Note 17 – Other Operating Expense

The components of Other Operating Expense were as follows:

Other Operating Expense increased compared to the prior-year quarter, primarily due to the accounting reclassification, partially offset by lower supplemental compensation plan expense. The lower supplemental compensation plan expense resulted in a related decrease in miscellaneous income reported in Other Operating Income.

Note 19 – Share-Based Compensation Plans

The Northern Trust Corporation 2017 Long-Term Incentive Plan provides for the grant of non-qualified and incentive stock options; tandem and free-standing stock appreciation rights; stock awards in the form of restricted stock, restricted stock units and other stock awards; and performance awards.

Beginning with the grants made on February 21, 2017 under the Corporation’s prior equity incentive plan, restricted stock unit and performance stock unit grants continue to vest in accordance with the original terms of the award if the applicable employee retires after satisfying applicable age and service requirements.

The Corporation granted 936,837 stock units awards with a total grant-date fair value of $106.0 million during the three months ended March 31, 2022, compared to 729,013 stock units awards with a total grant-date fair value of $70.4 million during the three months ended March 31, 2021. Compensation expense for the three months ended March 31, 2022 included $32.6 million attributable to restricted stock units granted to retirement-eligible employees that were expensed in their entirety on the date of grant, compared to $21.8 million in the prior-year quarter.

There were no non-qualified stock option grants in the three months ended March 31, 2022 and 2021.

The Corporation granted 211,906 performance stock units with a total grant-date fair value of $24.1 million during the three months ended March 31, 2022, compared to 200,066 performance stock units with a total grant-date fair value of $19.5 million during the three months ended March 31, 2021. Compensation expense for the three months ended March 31, 2022 included $16.2 million attributable to performance stock units granted to retirement-eligible employees that were expensed in their entirety on the date of grant, compared to $9.9 million in the prior-year quarter.

Restricted stock unit award compensation expense for the three months ended March 31, 2022 and 2021 included $5.7 million and $4.2 million, respectively, attributable to restricted stock units vested in full and expensed in their entirety upon date of grant.

Total compensation expense for share-based payment arrangements and the associated tax impacts were as follows for the three months ended March 31, 2022 and 2021.

Note 20 – Variable Interest Entities

Variable Interest Entities (VIEs) are defined within GAAP as entities which either (1) lack sufficient equity at risk to permit the entity to finance its activities without additional subordinated financial support, (2) have equity investors that lack attributes typical of an equity investor, such as the ability to make significant decisions through voting rights affecting the entity’s operations, or the obligation to absorb expected losses or the right to receive residual returns of the entity, or (3) are structured with voting rights that are disproportionate to the equity investor’s obligation to absorb losses or right to receive returns, and substantially all of the activities are conducted on behalf of the holder of the equity investment at risk with disproportionately few voting rights. Investors that finance a VIE through debt or equity interests are variable interest holders in the entity and the variable interest holder, if any, that has both the power to direct the activities that most significantly impact the entity’s economic performance and, through its variable interest, the obligation to absorb losses or the right to receive returns that could potentially be significant to the entity is deemed to be the VIE’s primary beneficiary and is required to consolidate the VIE.

Tax Credit Structures. Northern Trust invests in qualified affordable housing projects and community development entities (collectively, community development projects) that are designed to generate a return primarily through the realization of tax credits. The community development projects are formed as limited partnerships and limited liability companies in which Northern Trust invests as a limited partner/investor member through equity contributions. The economic performance of the community development projects, some of which are VIEs, is subject to the performance of their underlying investment and their ability to operate in compliance with the rules and regulations necessary for the qualification of tax credits generated by equity investments. Northern Trust has determined that it is not the primary beneficiary of any community development project VIEs as it lacks the power to direct the activities that most significantly impact the economic performance of the underlying investments or to affect their ability to operate in compliance with the rules and regulations necessary for the qualification of

64

Notes to Consolidated Financial Statements (unaudited) (continued)

tax credits generated by equity investments. This power is held by the general partners and managing members who exercise full and exclusive control of the operations of the community development project VIEs.

Northern Trust’s maximum exposure to loss as a result of its involvement with community development projects is limited to the carrying amounts of its investments, including any undrawn commitments. As of March 31, 2022 and December 31, 2021, the carrying amounts of these investments in community development projects that generate tax credits, included in Other Assets on the consolidated balance sheets, totaled $916.5 million and $916.8 million, respectively, of which $876.4 million and $880.0 million are VIEs as of March 31, 2022 and December 31, 2021, respectively. As of March 31, 2022 and December 31, 2021, liabilities related to unfunded commitments on investments in tax credit community development projects, included in Other Liabilities on the consolidated balance sheets, totaled $297.4 million and $289.3 million, respectively, of which $281.8 million and $280.5 million related to undrawn commitments on VIEs as of March 31, 2022 and December 31, 2021, respectively. Northern Trust’s funding requirements are limited to its invested capital and undrawn commitments for future equity contributions. Northern Trust has no exposure to loss from liquidity arrangements and no obligation to purchase assets of the community development projects.

Tax credits and other tax benefits attributable to community development projects totaled $22.7 million and $23.0 million for the three months ended March 31, 2022 and 2021, respectively.

Investment Funds. Northern Trust acts as asset manager for various funds in which clients of Northern Trust are investors. As an asset manager of funds, Northern Trust earns a competitively priced fee that is based on assets managed and varies with each fund’s investment objective. Based on its analysis, Northern Trust has determined that it is not the primary beneficiary of these VIEs under GAAP.

Some of the funds for which Northern Trust acts as asset manager comply or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds and therefore the funds are exempt from the consolidation requirements in ASC 810-10. Northern Trust voluntarily waived $50.7 million and $50.2 million of money market mutual fund fees for the three months ended March 31, 2022 and 2021, respectively, related to the low-interest-rate environment and certain competitive factors. Northern Trust does not have any contractual obligations to provide financial support to the funds. Any potential future support of the funds will be at the discretion of Northern Trust after an evaluation of the specific facts and circumstances.

Periodically, Northern Trust makes seed capital investments to certain funds. As of March 31, 2022, and December 31, 2021, Northern Trust had no seed capital investments and no unfunded commitments related to seed capital investments.

Note 21 – Commitments and Contingent Liabilities

Off-Balance Sheet Financial Instruments, Guarantees and Other Commitments. Northern Trust, in the normal course of business, enters into various types of commitments and issues letters of credit to meet the liquidity and credit enhancement needs of its clients. The contractual amounts of these instruments represent the maximum potential credit exposure should the instrument be fully drawn upon and the client default. To control the credit risk associated with entering into commitments and issuing letters of credit, Northern Trust subjects such activities to the same credit quality and monitoring controls as its lending activities. Northern Trust does not believe the total contractual amount of these instruments to be representative of its future credit exposure or funding requirements.

The following table provides details of Northern Trust's off-balance sheet financial instruments as of March 31, 2022 and December 31, 2021.

(2) These amounts include $35.7 million and $30.5 million of standby letters of credit secured by cash deposits or participated to others as of March 31, 2022 and December 31, 2021, respectively.

(3) These amounts include a $2,674.8 million and $2,309.6 million guarantee to the Fixed Income Clearing Corporation (FICC) under the sponsored member program, without taking into consideration the related collateral, as of March 31, 2022 and December 31, 2021, respectively.

65

Notes to Consolidated Financial Statements (unaudited) (continued)

Undrawn Commitments generally have fixed expiration dates or other termination clauses. Since a significant portion of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future loans or liquidity requirements.

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. 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 collateral received or other participants.

Financial Guarantees are issued by Northern Trust to guarantee the performance of a client to a third party under certain arrangements.

Commercial Letters of Credit are instruments issued by Northern Trust on behalf of its clients that authorize a third party (the beneficiary) to draw drafts up to a stipulated amount under the specified terms and conditions of the agreement and other similar instruments. Commercial letters of credit are issued primarily to facilitate international trade.

Custody Securities Lent with Indemnification involves Northern Trust lending securities owned by clients to borrowers who are reviewed and approved by the Northern Trust Capital Markets Credit Committee, as part of its securities custody activities and at the direction of its clients. In connection with these activities, Northern Trust has issued indemnifications to certain clients against certain losses that are a direct result of a borrower’s failure to return securities when due, should the value of such securities exceed the value of the collateral required to be posted. Borrowers are required to collateralize fully securities received with cash or marketable securities. As securities are loaned, collateral is maintained at a minimum of 100% of the fair value of the securities plus accrued interest. The collateral is revalued on a daily basis. The amount of securities loaned as of March 31, 2022 and December 31, 2021 subject to indemnification was $155.7 billion and $170.4 billion, respectively. Because of the credit quality of the borrowers and the requirement to fully collateralize securities borrowed, management believes that the exposure to credit loss from this activity is not significant and no liability was recorded as of March 31, 2022 or December 31, 2021, related to these indemnifications.

Unsettled Repurchase and Reverse Repurchase Agreements. Northern Trust enters into repurchase agreements and reverse repurchase agreements which may settle at a future date. In repurchase agreements, Northern Trust receives cash from and provides securities as collateral to a counterparty. In reverse repurchase agreements, Northern Trust advances cash to and receives securities as collateral from a counterparty. These transactions are recorded on the consolidated balance sheets on the settlement date. As of March 31, 2022 and December 31, 2021, there were no unsettled repurchase or reverse repurchase agreements.

Sponsored Member Program. Northern Trust is an approved Government Securities Division (GSD) netting and sponsoring member in the FICC sponsored member program, through which Northern Trust submits eligible repurchase and reverse repurchase transactions in U.S. Government securities between Northern Trust and its sponsored member clients for novation and clearing. Northern Trust may sponsor clients to clear their eligible repurchase transactions with the FICC. As a sponsoring member, Northern Trust guarantees to the FICC the prompt and full payment and performance of its sponsored member clients’ respective obligations under the FICC GSD’s rules. To mitigate Northern Trust’s credit exposure under this guarantee, Northern Trust obtains a security interest in its sponsored member clients’ collateral. See Note 23 — Offsetting of Assets and Liabilities for additional information on Northern Trust’s repurchase and reverse repurchase agreements.

Clearing and Settlement Organizations. The Bank is a participating member of various cash, securities and foreign exchange clearing and settlement organizations. It participates in these organizations on behalf of its clients and on its own behalf as a result of its own activities. A wide variety of cash and securities transactions are settled through these organizations, including those involving U.S. Treasuries, obligations of states and political subdivisions, asset-backed securities, commercial paper, dollar placements, and securities issued by the Government National Mortgage Association.

Certain of these industry clearing and settlement exchanges require their members to guarantee their obligations and liabilities and/or to provide liquidity support in the event other members do not honor their obligations as stipulated in each clearing organization’s membership agreement. Exposure related to these agreements varies, primarily as a result of fluctuations in the volume of transactions cleared through the organizations. At March 31, 2022 and December 31, 2021, Northern Trust has not recorded any material liabilities under these arrangements as Northern Trust believes the likelihood that a clearing or settlement exchange (of which Northern Trust is a member) would become insolvent is remote. Controls related to these clearing transactions are closely monitored by management to protect the assets of Northern Trust and its clients.

Legal Proceedings. In the normal course of business, the Corporation and its subsidiaries are routinely defendants in or parties to pending and threatened legal actions, and are subject to regulatory examinations, information-gathering requests, investigations, and proceedings, both formal and informal. In certain legal actions, claims for substantial monetary damages are

66

Notes to Consolidated Financial Statements (unaudited) (continued)

asserted. In regulatory matters, claims for disgorgement, restitution, penalties and/or other remedial actions or sanctions may be sought.

Based on current knowledge, after consultation with legal counsel and after taking into account current accruals, management does not believe that losses, fines or penalties, if any, arising from pending litigation or threatened legal actions or regulatory matters either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage will have a material adverse effect on the consolidated financial position or liquidity of the Corporation, although such matters could have a material adverse effect on the Corporation’s operating results for a particular period.

Under GAAP, (i) an event is “probable” if the “future event or events are likely to occur”; (ii) an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely”; and (iii) an event is “remote” if “the chance of the future event or events occurring is slight.”

The outcome of litigation and regulatory matters is inherently difficult to predict and/or the range of loss often cannot be reasonably estimated, particularly for matters that (i) will be decided by a jury, (ii) are in early stages, (iii) involve uncertainty as to the likelihood of a class being certified or the ultimate size of the class, (iv) are subject to appeals or motions, (v) involve significant factual issues to be resolved, including with respect to the amount of damages, (vi) do not specify the amount of damages sought or (vii) seek very large damages based on novel and complex damage and liability legal theories. Accordingly, the Corporation cannot reasonably estimate the eventual outcome of these pending matters, the timing of their ultimate resolution or what the eventual loss, fines or penalties, if any, related to each pending matter will be.

In accordance with applicable accounting guidance, the Corporation records accruals for litigation and regulatory matters when those matters present loss contingencies that are both probable and reasonably estimable. When loss contingencies are not both probable and reasonably estimable, the Corporation does not record accruals. No material accruals have been recorded for pending litigation or threatened legal actions or regulatory matters.

For a limited number of matters for which a loss is reasonably possible in future periods, whether in excess of an accrued liability or where there is no accrued liability, the Corporation is able to estimate a range of possible loss. As of March 31, 2022, the Corporation has estimated the range of reasonably possible loss for these matters to be from zero to approximately $25 million in the aggregate. The Corporation’s estimate with respect to the aggregate range of reasonably possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate.

In certain other pending matters, there may be a range of reasonably possible loss (including reasonably possible loss in excess of amounts accrued) that cannot be reasonably estimated for the reasons described above. Such matters are not included in the estimated range of reasonably possible loss discussed above.

In 2015, Northern Trust Fiduciary Services (Guernsey) Limited (NTFS), an indirect subsidiary of the Corporation, was charged by a French investigating magistrate judge with complicity in estate tax fraud in connection with the administration of two trusts for which it serves as trustee. Charges also were brought against a number of other persons and entities related to this matter. In 2017, a French court found no estate tax fraud had occurred and NTFS and all other persons and entities charged were acquitted. The Public Prosecutor’s Office of France appealed the court decision and in June 2018 a French appellate court issued its opinion on the matter, acquitting all persons and entities charged, including NTFS. In January 2021, the Cour de Cassation, the highest court in France, reversed the June 2018 appellate court ruling, requiring a re-trial at the appellate court level. The re-trial proceedings in the appellate court have not yet been scheduled. As trustee, NTFS provided no tax advice and had no involvement in the preparation or filing of the challenged estate tax filings.

Visa Class B Common Shares. Northern Trust, as a member of Visa U.S.A. Inc. (Visa U.S.A.) and in connection with the 2007 restructuring of Visa U.S.A. and its affiliates and the 2008 initial public offering of Visa Inc. (Visa), received certain Visa Class B common shares. The Visa Class B common shares are subject to certain selling restrictions until the final resolution of certain litigation related to interchange fees involving Visa (the covered litigation), at which time the shares are convertible into Visa Class A common shares based on a conversion rate dependent upon the ultimate cost of resolving the covered litigation. On June 28, 2018, September 27, 2019 and December 29, 2021, Visa deposited an additional $600 million, $300 million, and $250 million, respectively, into an escrow account previously established with respect to the covered litigation. As a result of the additional contributions to the escrow account, the rate at which Visa Class B common shares will convert into Visa Class A common shares was reduced.

In September 2018, Visa reached a proposed class settlement agreement covering damage claims but not injunctive relief claims regarding the covered litigation. In December 2019, the district court granted final approval for the proposed class settlement agreement. Certain merchants have opted out of the class settlement and are pursuing claims separately, while other merchants have appealed the approval order granted by the district court. The ultimate resolution of the covered litigation, the

67

Notes to Consolidated Financial Statements (unaudited) (continued)

timing for removal of the selling restrictions on the Visa Class B common shares and the rate at which such shares will ultimately convert into Visa Class A common shares are uncertain.

In June 2016 and 2015, Northern Trust recorded a $123.1 million and $99.9 million net gain on the sale of 1.1 million and 1.0 million of its Visa Class B common shares, respectively. These sales do not affect Northern Trust’s risk related to the impact of the covered litigation on the rate at which such shares will ultimately convert into Visa Class A common shares. Northern Trust continued to hold approximately 4.1 million Visa Class B common shares, which are recorded at their original cost basis of zero, as of March 31, 2022 and December 31, 2021.

Note 22 – Derivative Financial Instruments

Northern Trust is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients, as part of its trading activity for its own account and as part of its risk management activities. These instruments may include foreign exchange contracts, interest rate contracts, total return swap contracts, and swaps related to the sale of certain Visa Class B common shares.

Foreign exchange contracts are agreements to exchange specific amounts of currencies at a future date, at a specified rate of exchange. Foreign exchange contracts are entered into primarily to meet the foreign exchange needs of clients. Foreign exchange contracts are also used for trading and risk management purposes. For risk management purposes, Northern Trust uses foreign exchange contracts to reduce its exposure to changes in foreign exchange rates relating to certain forecasted non-functional-currency-denominated revenue and expenditure transactions, foreign-currency-denominated assets and liabilities, including debt securities, and net investments in non-U.S. affiliates.

Interest rate contracts include swap and option contracts. Interest rate swap contracts involve the exchange of fixed and floating rate interest payment obligations without the exchange of the underlying principal amounts. Northern Trust enters into interest rate swap contracts with its clients and also may utilize such contracts to reduce or eliminate the exposure to changes in the cash flows or fair value of hedged assets or liabilities due to changes in interest rates. Interest rate option contracts may include caps, floors, collars and swaptions, and provide for the transfer or reduction of interest rate risk, typically in exchange for a fee. Northern Trust enters into option contracts primarily as a seller of interest rate protection to clients. Northern Trust receives a fee at the outset of the agreement for the assumption of the risk of an unfavorable change in interest rates. This assumed interest rate risk is then mitigated by entering into an offsetting position with an outside counterparty. Northern Trust may also purchase or enter into option contracts for risk management purposes including to reduce the exposure to changes in the cash flows of hedged assets due to changes in interest rates.

Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheets. They are used merely to express the volume of this activity. Northern Trust’s credit-related risk of loss is limited to the positive fair value of the derivative instrument, net of any collateral received, which is significantly less than the notional amount.

All derivative financial instruments, whether designated as hedges or not, are recorded on the consolidated balance sheets at fair value within Other Assets or Other Liabilities. Northern Trust has elected to net derivative assets and liabilities when legally enforceable master netting arrangements or similar agreements exist between Northern Trust and the counterparty.

Hedging Derivative Instruments Designated under GAAP. Northern Trust uses derivative instruments to hedge its exposure to foreign currency, interest rate, and equity price. Certain hedging relationships are formally designated and qualify for hedge accounting under GAAP as fair value, cash flow or net investment hedges. Other derivatives that are entered into for risk management purposes as economic hedges are not formally designated as hedges and changes in fair value are recognized currently in Other Operating Income within the consolidated statements of income (see below section “Derivative Instruments Not Designated as Hedging under GAAP”).

In order to qualify for hedge accounting, a formal assessment is performed on a calendar-quarter basis to verify that derivatives used in designated hedging transactions continue to be highly effective in offsetting the changes in fair value or cash flows of the hedged item. If a derivative ceases to be highly effective, matures, is sold or is terminated, or if a hedged forecasted transaction is no longer probable of occurring, hedge accounting is terminated and the derivative is treated as if it were a trading instrument.

Fair Value Hedges. Derivatives are designated as fair value hedges to limit Northern Trust’s exposure to changes in the fair value of assets and liabilities due to movements in interest rates. Northern Trust enters into interest rate swaps to hedge changes in fair value of AFS debt securities and long-term subordinated debt and senior notes. Northern Trust applied the “shortcut” method of accounting, available under GAAP, which assumes there is perfect effectiveness in a hedge, for all of its fair value hedges during the three month periods ended March 31, 2022 and 2021. Changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability attributable to the hedged risk are recognized currently in earnings within the same income statement line item.

69

Notes to Consolidated Financial Statements (unaudited) (continued)

Cash Flow Hedges. Derivatives are also designated as cash flow hedges in order to minimize the variability in cash flows of earning assets or forecasted transactions caused by movements in interest or foreign exchange rates. Northern Trust enters into foreign exchange contracts to hedge changes in cash flows due to movements in foreign exchange rates of forecasted foreign- currency-denominated transactions and foreign-currency-denominated debt securities. Northern Trust also enters into interest rate contracts to hedge changes in cash flows due to movements in interest rates of AFS debt securities. The change in fair value of cash flow hedging derivative instruments are recorded in AOCI and reclassified to earnings when the hedged forecasted transaction impacts earnings within the same income statement line item.

There were no material gains or losses reclassified into earnings during the three month periods ended March 31, 2022 and 2021, as a result of the discontinuance of forecasted transactions that were no longer probable of occurring. It is estimated that net losses of $4.9 million will be reclassified into net income within the next twelve months relating to cash flow hedges of foreign-currency-denominated transactions. As of March 31, 2022, 17 months was the maximum length of time over which the exposure to variability in future cash flows of forecasted foreign-currency-denominated transactions was being hedged.

The following tables provide fair value and cash flow hedge derivative gains and losses recognized in income during the three-month periods ended March 31, 2022 and 2021.

Net Investment Hedges. Certain foreign exchange contracts are designated as net investment hedges to minimize Northern Trust’s exposure to variability in the foreign currency translation of net investments in non-U.S. branches and subsidiaries. Net investment hedge gains of $59.4 million and $82.7 million were recognized in AOCI related to foreign exchange contracts for the three months ended March 31, 2022 and 2021, respectively.

Derivative Instruments Not Designated as Hedging under GAAP. Northern Trust’s derivative instruments that are not designated as hedging under GAAP include derivatives for purposes of client-related and trading activities, as well as other risk management purposes. These activities consist principally of providing foreign exchange services to clients in connection with

70

Notes to Consolidated Financial Statements (unaudited) (continued)

Northern Trust’s global custody business. However, in the normal course of business, Northern Trust also engages in trading of currencies for its own account.

Non-designated risk management derivatives include foreign exchange contracts entered into to manage the foreign currency risk of non-U.S.-dollar-denominated assets and liabilities, the net investment in certain non-U.S. affiliates, commercial loans and forecasted foreign-currency-denominated transactions. Swaps related to sales of certain Visa Class B common shares were entered into pursuant to which Northern Trust retains the risks associated with the ultimate conversion of the Visa Class B common shares into Visa Class A common shares. Total return swaps are entered into to manage the equity price risk associated with certain investments.

Changes in the fair value of derivative instruments not designated as hedges under GAAP are recognized currently in income. The following table provides the location and amount of gains and losses recorded in the consolidated statements of income for the three months ended March 31, 2022 and 2021 for derivative instruments not designated as hedges under GAAP.

(1)Derivative liabilities are reported in Other Liabilities on the consolidated balance sheets. Other Liabilities (excluding derivative liabilities) totaled $3.3 billion at both March 31, 2022 and December 31, 2021.

(2)Offsetting of Securities Sold under Agreements to Repurchase primarily relates to our involvement in FICC.

(3)Including cash collateral deposited with counterparties.

(4)Including financial assets accepted as collateral which are deposited with counterparties.

(5)Northern Trust did not place any cash collateral with counterparties that was not offset in the consolidated balance sheets that could have been used to offset the net amounts presented in the consolidated balance sheets as of March 31, 2022 and December 31, 2021.

All of Northern Trust’s securities sold under agreements to repurchase (repurchase agreements) and securities purchased under agreements to resell (reverse repurchase agreements) involve the transfer of financial assets in exchange for cash subject to a right and obligation to repurchase those assets for an agreed upon amount. In the event of a repurchase failure, the cash or financial assets are available for offset. All of Northern Trust’s repurchase agreements and reverse repurchase agreements are subject to a master netting arrangement, which sets forth the rights and obligations for repurchase and offset. Under the master netting arrangement, Northern Trust is entitled to offset receivables from and collateral placed with a single counterparty against obligations owed to that counterparty. In addition, collateral held by Northern Trust can be offset against receivables from that counterparty. Northern Trust’s repurchase agreements and reverse repurchase agreements, other than those in which the counterparty is FICC, do not meet the requirements to net under GAAP.

Derivative asset and liability positions with a single counterparty can be offset against each other in cases where legally enforceable master netting arrangements or similar agreements exist. Derivative assets and liabilities can be further offset by cash collateral received from, and deposited with, the transacting counterparty. The basis for this view is that, upon termination of transactions subject to a master netting arrangement or similar agreement, the individual derivative receivables do not represent resources to which general creditors have rights and individual derivative payables do not represent claims that are equivalent to the claims of general creditors.

Credit risk associated with derivative instruments relates to the failure of the counterparty and the failure of Northern Trust to pay based on the contractual terms of the agreement, and is generally limited to the unrealized fair value gains and losses on these instruments, net of any collateral received or deposited. The amount of credit risk will increase or decrease during the

73

Notes to Consolidated Financial Statements (unaudited) (continued)

lives of the instruments as interest rates, foreign exchange rates, or equity prices fluctuate. Northern Trust’s risk is controlled by limiting such activity to an approved list of counterparties and by subjecting such activity to the same credit and quality controls as are followed in lending and investment activities. Credit Support Annexes and other similar agreements are currently in place with a number of Northern Trust’s counterparties which mitigate the aforementioned credit risk associated with derivative activity conducted with those counterparties by requiring that significant net unrealized fair value gains be supported by collateral placed with Northern Trust.

Additional cash collateral received from and deposited with derivative counterparties totaling $257.5 million and $150.5 million, respectively, as of March 31, 2022, and $93.5 million and $43.4 million, respectively, as of December 31, 2021, was not offset against derivative assets and liabilities in the consolidated balance sheets as the amounts exceeded the net derivative positions with those counterparties.

Certain master netting arrangements Northern Trust enters into with derivative counterparties contain credit-risk-related contingent features in which the counterparty has the option to declare Northern Trust in default and accelerate cash settlement of net derivative liabilities with the counterparty in the event Northern Trust’s credit rating falls below specified levels. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position was $1,163.8 million and $111.5 million at March 31, 2022 and December 31, 2021, respectively. Cash collateral amounts deposited with derivative counterparties on those dates included $1,068.3 million and $84.2 million, respectively, posted against these liabilities, resulting in a net maximum amount of termination payments that could have been required at March 31, 2022 and December 31, 2021, of $95.5 million and $27.3 million, respectively. Accelerated settlement of these liabilities would not have a material effect on the consolidated financial position or liquidity of Northern Trust.

Item 4. Controls and Procedures

As of March 31, 2022, the Corporation’s management, with the participation of the Corporation’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Corporation’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), that are designed to ensure that information required to be disclosed by the Corporation in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms. Based on such evaluation, such officers have concluded that, as of March 31, 2022, the Corporation’s disclosure controls and procedures are effective.

There have been no changes in the Corporation’s internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15 and 15d-15 under the Exchange Act during the last fiscal quarter that have materially affected, or that are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

Average Annual Rate of Return on Equity	≤ 6.0%	9.0%	12.0%	≥ 15.0%
PSU Multiplier	0%	50%	100%	150%

Any PSUs that do not become vested in accordance with the foregoing table shall be forfeited.

(b) The Corporation will issue you one (1) share of Common Stock in settlement of each vested PSU.

(c) For purposes of these Terms and Conditions:

(i) The average annual rate of return on equity for the Performance Period attained by the Corporation is the return on average common equity, based on the Corporation’s net income, and shall be determined by the Committee in its sole and absolute discretion in accordance with generally accepted accounting principles (subject to the adjustments set forth below). For purposes of the foregoing, the average annual rate of return on equity shall be calculated as the simple average annual rate of return on equity for the three-year Performance Period measured across the Corporation as a whole.

(ii) Notwithstanding anything herein to the contrary, for purposes of determining the average annual rate of return on equity for any individual fiscal year of the Corporation within the Performance Period, if any of the following items, individually or aggregated with other items as reflected herein, would produce a change to net income in excess of $50 million, net income shall be determined for such fiscal year by excluding such item(s) as aggregated:

(A) the gains or losses resulting from, and the expenses incurred in connection with, the acquisition or disposition of a business, a merger, or a similar transaction, and integration in connection therewith;

(B) the impact of securities issuances in connection with events described in item (A), above, and expenses incurred in connection therewith;

(C) any gain, loss, income or expense resulting from changes in accounting principles, tax laws, or other laws or provisions affecting reported results, that become effective during the Performance Period;

(D) any gain or loss resulting from, and expenses incurred in connection with, any litigation or regulatory investigations;

(E) any charges and expenses incurred in connection with restructuring activity, including but not limited to, reductions in force;

(F) the impact of discontinued operations;

(G) asset write-downs;

(H) the impact of goodwill impairment; or

- 2 -

(I) any other gain, loss, income or expense with respect to the Performance Period that is extraordinary, unusual and/or infrequent and not related to normal operations.

All amounts referenced in the foregoing list shall be determined in accordance with GAAP and shall be consistent with the Corporation’s financial disclosures. Further, the Committee’s determination of the average annual rate of return on equity for a Performance Period shall be final.

4. Average Annual Rate of Return on Equity Relative to Performance Peer Group.

(a) If you remain in the continuous and uninterrupted employment with your Employer through the Vesting Date (except as otherwise provided in Section 6), you shall become vested in the percentage of the applicable PSUs determined based on the Corporation’s average annual rate of return on equity relative to the Performance Peer Group for the Performance Period using the following table (applying straight line interpolation rounded to the nearest whole number of PSUs for the Corporation's achievement falling between the applicable thresholds):

Ranking	< 25th percentile	25th percentile	50th percentile	Highest ROE
PSU Multiplier	0%	50%	100%	150%

Any PSUs that do not become vested in accordance with the foregoing table shall be forfeited.

(b) The Corporation will issue you one (1) share of Common Stock in settlement of each vested PSU.

(c) For purposes of these Terms and Conditions, the average annual rate of return on equity for the Performance Period attained by the Corporation shall be determined by the Committee in its sole and absolute discretion by reference to the Corporation's reported annual rate of return as reflected on its audited consolidated financial statements for each year in the Performance Period.. For purposes of the foregoing, the average annual rate of return on equity shall be calculated as the sum of the annual rate of return on equity for the three-year Performance Period measured across the Corporation as a whole, divided by three (3).

(d) The average annual rate of return on equity for each member of the Performance Peer Group shall be determined by the Committee in its sole and absolute discretion by reference to the member's reported annual rate of return as reflected on its audited consolidated financial statements for each year in the Performance Period.

5. Dividend Equivalents. Upon the payment of any dividends on the shares of Common Stock occurring during the period preceding the settlement of your PSUs pursuant to these Terms and Conditions, the Corporation shall credit to you an amount in cash equal in value to the dividends that you would have received had you been the actual owner of the number of

- 3 -

shares of Common Stock represented by the number of PSUs earned as of the end of the Performance Period. The payment of any dividend equivalents as provided herein shall be made as soon as administratively practicable following the Vesting Date (but in no event later than 60 days following the Vesting Date).

6. Termination of Employment. Upon the termination of your employment with your Employer, your right to receive the shares of Common Stock issuable pursuant to the PSUs shall be only as follows:

(a) Cause. Notwithstanding anything to the contrary contained in these Terms and Conditions, if your Employer terminates your employment for Cause, your PSUs, whether vested but unsettled or unvested, immediately shall terminate and be forfeited.

(b) Disability and Death. If you cease to be an Employee by reason of Disability or death prior to the Vesting Date, you or your estate will become vested in the Actual PSUs as of the Vesting Date and you, your legal representative or your estate will receive the underlying shares of Common Stock pursuant to the vested PSUs.

(c) Retirement. If (i) you cease to be an Employee by reason of Retirement, and (ii) you provide Retirement Notice, you will become vested in the Actual PSUs as of the Vesting Date and you will receive the underlying shares of Common Stock pursuant to the vested PSUs. However, if you cease to be Retired from the Industry (as determined by the Committee in its sole discretion), any PSUs immediately shall terminate and be forfeited. Notwithstanding the foregoing, you will continue to vest in your PSUs pursuant to this Section 3(c) regardless of whether you cease to be Retired from the Industry if (i) your termination qualifies as a Mutual Agreement Termination, (ii) you cease to be an employee by reason of Disability, or (iii) a forfeiture upon your ceasing to be Retired from the Industry would violate applicable law.

(d) Mutual Agreement Termination. If you cease to be an Employee and your termination qualifies as a Mutual Agreement Termination, you will become vested in the Actual PSUs as of the Vesting Date and you will receive the underlying shares of Common Stock pursuant to the vested PSUs.

(e) Other Termination Events. If you cease to be an Employee prior to the date that your PSUs become vested for any reason other than those provided above, your PSUs shall terminate and be forfeited as of your Termination Date.

(f) Form and Timing of Settlement. Notwithstanding the foregoing, the Corporation may, in its sole discretion, settle your PSUs in the form of: (i) a cash payment to the extent settlement in shares of Common Stock (1) is prohibited under local law, (2) would require you or the Corporation to obtain the approval of any governmental and/or regulatory body in your country of residence (and/or country of employment, if different) or (3) is administratively burdensome or (ii) shares of Common Stock, but require you to immediately sell such shares of Common Stock (in which case, the Corporation shall have the authority to issue sales instructions in relation to such shares of Common Stock on your behalf). Also, the PSUs shall be

- 4 -

settled as soon as administratively practicable following the Vesting Date (but in no event later than March 15 of the calendar year following the calendar year in which the Performance Period ends).

7. Treatment Upon Change in Control.

(a) General. Except as may be otherwise provided in an agreement executed by the Corporation (and, where applicable, approved by the Corporation’s shareholders) addressing a Change in Control and which does not materially impair your rights under the PSUs, your PSUs shall be treated in accordance with the following provisions in the event of a Change in Control.

(b) Conversion of PSUs by Acquirer. In the event of a Change in Control, the PSUs shall be converted to unvested restricted stock units settled in shares of the acquirer’s common stock (an “Acquirer Stock Unit”) as follows:

(i) Acquirer Unvested Stock Units Based Upon Corporation Performance: A pro-rata number of the PSUs shall be converted into time-based, unvested restricted stock units over shares of the acquirer’s common stock (with an equivalent intrinsic value) based upon the Corporation’s average annual rate of return on equity and the Corporation's average annual rate of return on equity relative to the Performance Peer Group as computed for the Abbreviated Performance Period (an “Acquirer Unvested Performance-Related Stock Unit”) where: (1) the Corporation’s average annual rate of return on equity and the Corporation's average annual rate of return on equity relative to the Performance Peer Group shall be computed on the basis of the Abbreviated Performance Period; (2) the PSU Multiplier shall be determined based upon the Corporation’s average annual rate of return on equity and the Corporation's average annual rate of return on equity relative to the Performance Peer Group for the Abbreviated Performance Period; (3) the pro-ration shall be done on the basis of the Pre-Change in Control Pro-Ration Factor; and (4) the terms and conditions of each Acquirer Unvested Performance-Related Stock Unit shall be the same in all material respects as the terms and conditions of the original PSUs, with the exception that you shall vest in each Acquirer Unvested Performance-Related Stock Unit on the basis of your continuous employment from the date of the Change in Control through the end of the original Performance Period plus one (1) day (the “Post-Change Vesting Date”). Upon vesting, each vested Acquirer Unvested Performance-Related Stock Unit will be settled in one (1) share of the acquirer’s common stock as soon as administratively practicable following the Post-Change Vesting Date (but in no event later than 60 days following the Post-Change Vesting Date). Upon a Qualifying Termination prior to the Post-Change Vesting Date, you shall become fully vested in each Acquirer Unvested Performance-Related Stock Unit and each vested Acquirer Unvested Performance-Related Stock Unit shall be settled (in one share (1) of the acquirer’s common stock) as soon as administratively practicable following such Qualifying Termination (but in no event later than 60 days following the Qualifying Termination).

(ii) Acquirer Unvested Stock Units: A pro-rata number of the PSUs shall be converted into time-based, unvested restricted stock units over shares of the acquirer’s common stock (with an equivalent intrinsic value; an “Acquirer Unvested Stock Unit”) where:

- 5 -

(1) the number of PSUs subject to conversion to Acquirer Unvested Stock Units shall be computed on the basis of a PSU Multiplier equal to 100%, (2) the pro-ration shall be done on the basis of the Post-Change in Control Pro-Ration Factor, and (3) the terms and conditions of each Acquirer Unvested Stock Unit shall be the same in all material respects as the terms and conditions of the original PSU, with the exception that you shall vest in each Acquirer Unvested Stock Unit on the basis of your continuous employment from the date of the Change in Control through the Post-Change Vesting Date. Upon vesting, each vested Acquirer Unvested Stock Unit will be settled in one (1) share of the acquirer’s common stock as soon as administratively practicable following the Post-Change Vesting Date (but in no event later than 60 days following the Post-Change Vesting Date). Upon a Qualifying Termination prior to the Post-Change Vesting Date, you shall become fully vested in each Acquirer Unvested Stock Unit and each vested Acquirer Unvested Stock Unit shall be settled (in one share (1) of the acquirer’s common stock) as soon as administratively practicable following such Qualifying Termination (but in no event later than 60 days following the Qualifying Termination). For purposes of the foregoing and to the extent possible, the conversion of PSUs into Acquirer Unvested Stock Units shall be effectuated in accordance with the applicable provisions of the Code (and the related Treasury Regulations) and the applicable provisions of the laws of your country of residence and/or country of employment such that the conversion is tax neutral and itself does not trigger a taxable event to you, the Corporation, your Employer or the acquirer.

(c) Cashout of PSUs. In the event of a Change in Control where the acquirer does not convert the PSUs in accordance with the provisions of Section 6(b), you shall become vested in the PSUs as follows:

(i) Cashout of Vested PSUs Based Upon Corporation Performance: A pro-rata number of the PSUs shall become vested based upon the Corporation’s average annual rate of return on equity and the Corporation's average annual rate of return on equity relative to the Performance Peer Group as computed for the Abbreviated Performance Period where: (1) the Corporation’s average annual rate of return on equity and the Corporation's average annual rate of return on equity relative to the Performance Peer Group shall be computed on the basis of the Abbreviated Performance Period, (2) the PSU Multiplier shall be determined based upon the Corporation’s average annual rate of return on equity and the Corporation's average annual rate of return on equity relative to the Performance Peer Group for the Abbreviated Performance Period, and (3) the pro-ration shall be done on the basis of the Pre-Change in Control Pro-Ration Factor. Upon vesting, each vested PSU shall be cancelled by the Corporation in exchange for a cash payment equal to the aggregate consideration paid to each shareholder of one (1) share of Common Stock upon the Change in Control. Such cash payment shall be made as soon as administratively practicable following the Change in Control (but in no event later than 60 days following the Change in Control) in such manner and in accordance with such procedures as the Committee may determine in its sole discretion.

(ii) Cashout of Vested PSUs Based on Target: Another pro-rata number of the PSUs shall become vested where: (1) the number of PSUs subject to vesting shall be computed on the basis of a PSU Multiplier equal to 100%, and (2) the PSUs will be subject to the Post-Change Pro-Ration Factor. Upon vesting, each vested PSU shall be cancelled by the Corporation in exchange for a cash payment equal to the aggregate consideration paid to each

- 6 -

shareholder of one (1) share of Common Stock upon the Change in Control. Such cash payment shall be made as soon as administratively practicable following the Change in Control (but in no event later than 60 days following the Change in Control) in such manner and in accordance with such procedures as the Committee may determine in its sole discretion.

8. Legal and Tax Compliance; Cooperation. If you are resident and/or are employed outside of the United States, you agree, as a condition of the grant of the PSUs, to repatriate all payments attributable to the shares of Common Stock and/or cash acquired under the 2017 Plan (including, but not limited to, dividends, dividend equivalents and any proceeds derived from the sale of the shares of Common Stock acquired pursuant to the PSUs) if required by and in accordance with local foreign exchange rules and regulations in your country of residence (and/or country of employment, if different). In addition, you also agree to take any and all actions, and consent to any and all actions taken by the Corporation and its Subsidiaries, as may be required to allow the Corporation and its Subsidiaries to comply with local laws, rules and regulations in your country of residence (and/or country of employment, if different). Finally, you agree to take any and all actions as may be required to comply with your personal legal and tax obligations under local laws, rules and regulations in your country of residence (and/or country of employment, if different).

9. Age Discrimination Rules. If you are resident and/or employed in a country that is a member of the European Union, the grant of the PSUs and these Terms and Conditions are intended to comply with the Age Discrimination Rules. To the extent that a court or tribunal of competent jurisdiction determines that any provision of the Terms and Conditions are invalid or unenforceable, in whole or in part, under the Age Discrimination Rules, the Corporation, in its sole discretion, shall have the power and authority to revise or strike such provision to the minimum extent necessary to make it valid and enforceable to the full extent permitted under local law.

10. Withholding of Tax-Related Items.

(a) Regardless of any action the Corporation and/or your Employer take with respect to any or all Tax-Related Items, you acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that the Corporation and your Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PSUs, including the grant of the PSUs, the vesting of the PSUs, the subsequent sale of any shares of Common Stock acquired pursuant to the PSUs and the receipt of any dividends or dividend equivalents and (ii) do not commit to structure the terms of the grant or any aspect of the PSUs to reduce or eliminate your liability for Tax-Related Items.

(b) Prior to the delivery of shares of Common Stock upon the vesting of your PSUs, if your country of residence (and/or country of employment, if different) requires withholding of Tax-Related Items, the Corporation shall withhold a sufficient number of whole shares of Common Stock otherwise issuable upon the vesting of the PSUs that have an aggregate Fair Market Value sufficient to pay the Tax-Related Items required to be withheld with respect to

- 7 -

the shares of Common Stock. The cash equivalent of the shares of Common Stock withheld will be used to settle the obligation to withhold the Tax-Related Items. In the event that withholding in shares of Common Stock is prohibited or problematic under applicable law or otherwise may trigger adverse consequences to the Corporation or your Employer, your Employer may withhold the Tax-Related Items required to be withheld with respect to the shares of Common Stock in cash from your regular salary and/or wages or any other amounts payable to you. In the event the withholding requirements are not satisfied through the withholding of shares of Common Stock by the Corporation or through your regular salary and/or wages or other amounts payable to you by your Employer, no shares of Common Stock will be issued to you (or your estate) upon vesting of the PSUs unless and until satisfactory arrangements (as determined by the Corporation) have been made by you with respect to the payment of any Tax-Related Items that the Corporation or your Employer determines, in its sole discretion, must be withheld or collected with respect to such PSUs.

(c) By accepting these PSUs, you expressly consent to the foregoing methods of withholding as provided for hereunder. All other Tax-Related Items related to the PSUs and any shares of Common Stock delivered in settlement thereof are your sole responsibility.

11. Code Section 409A.

(a) The PSUs are intended to comply with or be exempt from the requirements of Code Section 409A. The 2017 Plan and these Terms and Conditions shall be administered and interpreted in a manner consistent with this intent. If the Corporation determines that these Terms and Conditions are subject to Code Section 409A and that they do not comply with or are inconsistent with the applicable requirements, the Corporation may, in its sole discretion, and without your consent, amend these Terms and Conditions to cause them to comply with Code Section 409A or be exempt from Code Section 409A.

(b) Notwithstanding any provision of these Terms and Conditions to the contrary, in the event that any settlement or payment of the PSUs occurs as a result of your termination of employment and the Corporation determines that you are a “specified employee” (within the meaning of Code Section 409A) subject to Code Section 409A at the time of your termination of employment, and provided further that such payment or settlement does not otherwise qualify for an applicable exemption from Code Section 409A, then no such settlement or payment shall be paid to you until the date that is the earlier to occur of: (i) your death, or (ii) six (6) months and one (1) day following your termination of employment.Any portion of the PSUs where settlement is delayed as a result of the foregoing, which is (i) in whole or in part, settled in cash and (ii) based on the value of a share of Common Stock, shall be based on the value of a share of Common Stock at the time the PSUs otherwise would have been settled or paid without application of the delay described in the foregoing sentence.If the PSUs do not otherwise qualify for an applicable exemption from Code Section 409A, the terms “Retirement,” “terminate,” “termination,” “termination of employment,” and variations thereof as used in these Terms and Conditions are intended to mean a “separation from service” as such term is defined under Code Section 409A.

- 8 -

(c) Although these Terms and Conditions and the payments provided hereunder are intended to be exempt from or to otherwise comply with the requirements of Code Section 409A, the Corporation does not represent or warrant that these Terms and Conditions or the payments provided hereunder will comply with Code Section 409A or any other provisions of federal, state, local, or non-U.S. law. Neither the Corporation, its Subsidiaries, your Employer or their respective directors, officers, employees or advisers shall be liable to you (or any other individual claiming a benefit through you) for any tax, interest, or penalties you may owe as a result of compensation paid under these Terms and Conditions, and the Corporation, its Subsidiaries and your Employer shall have no obligation to indemnify or otherwise protect you from the obligation to pay any taxes pursuant to Code Section 409A.

12. Forfeitures and Recoupment

(a) Recoupment Policy. In addition to these Terms and Conditions, your PSUs and any shares of Common Stock issued to you pursuant to the PSUs shall be subject to the provisions of the Northern Trust Corporation Policy on Recoupment, as may be subsequently amended from time to time (the “Policy”).

(b) Delegation of Authority to Corporation. For purposes of the foregoing, you expressly and explicitly authorize the Corporation to issue instructions, on your behalf, to any brokerage firm and/or third party administrator engaged by the Corporation to hold your shares of Common Stock and other amounts acquired pursuant to your PSUs to re-convey, transfer or otherwise return such shares of Common Stock and/or other amounts to the Corporation upon the Corporation's enforcement of the Policy. To the extent that these Terms and Conditions and the Policy conflict, the terms of the Policy shall prevail.

13. Nontransferability. The PSUs shall be transferable only by will or the laws of descent and distribution. If you purport to make any transfer of the PSUs, except as aforesaid, the PSUs and all rights thereunder shall terminate immediately.

14. Securities Laws. The PSUs shall not be vested in whole or in part, and the Corporation shall not be obligated to issue any shares of Common Stock subject to the PSUs, if such issuance would, in the opinion of counsel for the Corporation, violate the Securities Act of 1933 or any other U.S. federal, state or non-U.S. laws having similar requirements as it may be in effect at the time. The PSUs are subject to the further requirement that, if at any time the Board of Directors of the Corporation shall determine in its discretion that the listing or qualification of the shares of Common Stock subject to the PSUs under any securities exchange requirements or under any applicable law, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of or in connection with the issuance of shares of Common Stock pursuant to the PSUs, the PSUs may not be vested in whole or in part unless such listing, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Corporation.

15. No Right of Continued Employment. The grant of the PSUs shall not confer upon you any right to continue in the employ of your Employer nor limit in any way the right of your

- 9 -

Employer to terminate your employment at any time. You shall have no rights as a shareholder of the Corporation with respect to any shares of Common Stock issuable upon the vesting of the PSUs until the date of issuance of such shares of Common Stock.

16. Discretionary Nature; No Vested Rights. You acknowledge and agree that the 2017 Plan is discretionary in nature and may be amended, cancelled, or terminated by the Corporation, in its sole discretion, at any time. The grant of the PSUs under the 2017 Plan is a one-time benefit and does not create any contractual or other right to receive a grant of PSUs or any other award under the 2017 Plan or other benefits in lieu thereof in the future. Future grants, if any, will be at the sole discretion of the Corporation, including, but not limited to, the form and timing of any grant, the number of shares of Common Stock subject to the grant and the vesting provisions. Any amendment, modification or termination of the 2017 Plan shall not constitute a change or impairment of the terms and conditions of your employment with your Employer.

17. Extraordinary Benefit. Your participation in the 2017 Plan is voluntary. The value of the PSUs and any other awards granted under the 2017 Plan is an extraordinary item of compensation outside the scope of your employment (and your employment contract, if any). Any grant under the 2017 Plan, including the grant of the PSUs, is not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension, or retirement benefits or similar payments.

18. Heirs. These Terms and Conditions shall bind and inure to the benefit of the Corporation, its successors and assigns, and you and your estate in the event of your death.

19. Data Privacy. The Corporation is located at 50 S. LaSalle Street, Chicago, Illinois 60603, United States of America, and grants PSUs under the 2017 Plan to employees of the Corporation and its Subsidiaries in its sole discretion. In conjunction with the Corporation’s grant of the PSUs under the 2017 Plan and its ongoing administration of such awards, the Corporation is providing the following information about its data collection, processing and transfer practices. In accepting the grant of the PSUs, you expressly and explicitly consent to the personal data activities as described herein.

(a)Data Collection, Processing and Usage. The Corporation collects, processes and uses your personal data, including your name, home address, email address, telephone number, date of birth, social insurance number or other identification number, salary, citizenship, job title, any shares of Common Stock or directorships held in the Corporation, and details of all PSUs or any other equity compensation awards granted, canceled, exercised, vested, or outstanding in your favor, which the Corporation receives from you or your Employer. In granting the PSUs under the 2017 Plan, the Corporation will collect your personal data for purposes of allocating shares of Common Stock and implementing, administering and managing the 2017 Plan. The Corporation’s legal basis for the collection, processing and usage of your personal data is your consent.

(b)Stock Plan Administration Service Provider. The Corporation transfers your personal data to Fidelity Stock Plan Services, LLC, an independent service provider based in the United States of America, which assists the Corporation with the implementation, administration

- 10 -

and management of the 2017 Plan (the “Stock Plan Administrator”). In the future, the Corporation may select a different Stock Plan Administrator and share your personal data with another company that serves in a similar manner. The Stock Plan Administrator will open an account for you to receive and trade shares of Common Stock acquired under the 2017 Plan. You will be asked to agree on separate terms and data processing practices with the Stock Plan Administrator, which is a condition to your ability to participate in the 2017 Plan.

(c)International Data Transfers. The Corporation and the Stock Plan Administrator are based in the United States of America. You should note that your country of residence may have enacted data privacy laws that are different from the United States of America. The Corporation’s legal basis for the transfer of your personal data to the United States of America is your consent.

(d)Voluntariness and Consequences of Consent Denial or Withdrawal. Your participation in the 2017 Plan and your grant of consent is purely voluntary. You may deny or withdraw your consent at any time. If you do not consent, or if you later withdraw your consent, you may be unable to participate in the 2017 Plan. This would not affect your existing employment or salary; instead, you merely may forfeit the opportunities associated with the 2017 Plan.

(e)Data Subjects Rights. You may have a number of rights under the data privacy laws in your country of residence. For example, your rights may include the right to (i) request access or copies of personal data the Corporation processes, (ii) request rectification of incorrect data, (iii) request deletion of data, (iv) place restrictions on processing, (v) lodge complaints with competent authorities in your country of residence, and/or (vi) request a list with the names and addresses of any potential recipients of your personal data. To receive clarification regarding your rights or to exercise your rights, you should contact privacy_compliance@ntrs.com.

20. Private Placement. If you are a resident and/or employed outside of the United States, you acknowledge that the grant of the PSUs is not intended to be a public offering of securities in your country of residence (and/or country of employment, if different). You further acknowledge that the Corporation has not submitted any registration statement, prospectus or other filing with any securities authority other than the U.S. Securities and Exchange Commission with respect to the grant of the PSUs, unless otherwise required under local law. No employee of the Corporation is permitted to advise you on whether you should acquire shares of Common Stock under the 2017 Plan or provide you with any legal, tax or financial advice with respect to the grant of the PSUs. The acquisition of shares of Common Stock involves certain risks, and you should carefully consider all risk factors and tax considerations relevant to the acquisition of shares of Common Stock under the 2017 Plan and the disposition of them. Further, you should carefully review all of the materials related to the PSUs and the 2017 Plan, and you should consult with your personal legal, tax and financial advisors for professional advice in relation to your personal circumstances.

21. Governing Law. All questions concerning the construction, validity and interpretation of the PSUs and the 2017 Plan shall be governed and construed according to the laws of the state of Delaware, without regard to the application of the conflicts of laws provisions

- 11 -

thereof. Any disputes regarding the PSUs or the 2017 Plan shall be brought only in the state or federal courts of the state of Delaware.

22. Electronic Delivery. The Corporation may, in its sole discretion, decide to deliver any documents related to the PSUs or other awards granted to you under the 2017 Plan by electronic means. You hereby consent to receive such documents by electronic delivery and agree to participate in the 2017 Plan through an on-line or electronic system established and maintained by the Corporation or a third party designated by the Corporation.

23. Severability. The invalidity or unenforceability of any provision of the 2017 Plan or these Terms and Conditions shall not affect the validity or enforceability of any other provision of the 2017 Plan or these Terms and Conditions.

24. English Language. If you are resident and/or employed outside of the United States, you acknowledge and agree that it is your express intent that these Terms and Conditions, the 2017 Plan and all other documents, notices and legal proceedings entered into, given or instituted pursuant to the PSUs be drawn up in English. If you have received these Terms and Conditions, the 2017 Plan or any other documents related to the PSUs translated into a language other than English and the meaning of the translated version is different than the English version, the English version will control.

25. Addendum. Notwithstanding any provisions of these Terms and Conditions to the contrary, the PSUs shall be subject to any special terms and conditions for your country of residence (and/or country of employment, if different) set forth in an addendum to these Terms and Conditions (an “Addendum”). Further, if you transfer your residence and/or employment to another country reflected in an Addendum to these Terms and Conditions at the time of transfer, the special terms and conditions for such country will apply to you to the extent the Corporation determines, in its sole discretion, that the application of such special terms and conditions is necessary or advisable in order to comply with local law, rules and regulations, or to facilitate the operation and administration of the PSUs and the 2017 Plan (or the Corporation may establish alternative terms and conditions as may be necessary or advisable to accommodate your transfer). In all circumstances, any applicable Addendum shall constitute part of these Terms and Conditions.

26. Insider Trading. By participating in the 2017 Plan, you expressly agree to comply with the Corporation’s Securities Transactions Policy and Procedures and any other of its policies regarding insider trading or personal account dealing applicable to you. Further, you expressly acknowledge and agree that, depending on the country of residence of you or your broker, or where the shares of Common Stock are listed, you may be subject to insider trading restrictions and/or market abuse laws which may affect your ability to accept, acquire, sell or otherwise dispose of shares of Common Stock, rights to shares of Common Stock (e.g., PSUs) or rights linked to the value of the shares of Common Stock, during such times you are considered to have material non-public information, “inside information” or similar types of information regarding the Corporation as defined by laws or regulations in the applicable country. Local insider trading laws and regulations may prohibit the cancellation or amendment of orders you

- 12 -

place before you possessed such information. Furthermore, you may be prohibited from (a) disclosing such information to any third party (other than on a “need to know” basis) and (b) “tipping” third parties or causing them otherwise to buy or sell securities (including other employees of the Corporation and its Subsidiaries). Any restriction under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Corporation policies. You expressly acknowledge and agree that it is your responsibility to comply with any applicable restrictions, and you should consult your personal advisor for additional information on any trading restrictions that may apply to you.

27. Additional Requirements; Amendments. The Corporation reserves the right to impose other requirements on the PSUs, any shares of Common Stock acquired pursuant to the PSUs and your participation in the 2017 Plan to the extent the Corporation determines, in its sole discretion, that such other requirements are necessary or advisable in order to comply with local law, rules and regulations, or to facilitate the operation and administration of the PSUs and the 2017 Plan. Such requirements may include (but are not limited to) requiring you to sign any agreements or undertakings that may be necessary to accomplish the foregoing.

You acknowledge and agree that you will have no entitlement to compensation or damages in consequence of the termination of your employment with the Corporation and your Employer for any reason whatsoever and whether or not in breach of contract, insofar as any purported claim to such entitlement arises or may arise from your ceasing to have rights under or to be entitled to vest in the PSUs as a result of such termination of employment (whether the termination is in breach of contract or otherwise), or from the loss or diminution in value of the PSUs. Upon the grant of the PSUs, you shall be deemed irrevocably to have waived any such entitlement.

(a)Review Period. You have a minimum of 14 calendar days to consider these Terms and Conditions (measured from the date on which the Corporation provides these Terms and Conditions to you) before accepting the grant of PSUs (the “Review Period”).

In the case of a conflict between these Terms and Conditions, the Award Notice and the terms of the 2017 Plan, the provisions of the 2017 Plan will govern. Capitalized terms used but not defined herein have the meaning provided therefor in the 2017 Plan.

2. Vesting and Settlement; Dividend Equivalents. Your right to receive the shares of Common Stock issuable pursuant to the Stock Units shall be only as follows:

(a) Normal Vesting. If you continue to be an Employee, you will receive the shares of Common Stock underlying the Stock Units that have become vested pursuant to the following vesting schedule (unless otherwise specified in Exhibit I):

Second anniversary of the Measurement Date	25%
Third anniversary of the Measurement Date	25%

(b) Cause. Notwithstanding anything to the contrary contained in these Terms and Conditions, if your Employer terminates your employment for Cause, your Stock Units, whether vested but unsettled or unvested, immediately shall terminate and be forfeited.

(c) Disability and Death. If you cease to be an Employee by reason of Disability or death prior to the date that your Stock Units become fully vested, you or your estate will become fully vested in your Stock Units, and you, your legal representative or your estate will receive all of the underlying shares of Common Stock.

(d) Retirement. If you cease to be an Employee by reason of Retirement prior to the date that your Stock Units become fully vested, you will continue to vest in your unvested Stock Units pursuant to Section 2(a) above and once vested, you will receive the underlying shares of Common Stock pursuant to the Stock Units that become vested hereunder following the originally contemplated Vesting Date(s). However, if you cease to be Retired from the Industry (as determined by the Committee in its sole discretion), any Stock Units (whether vested but

unsettled or unvested) immediately shall terminate and be forfeited. Notwithstanding the foregoing, you will continue to vest in your unvested Stock Units pursuant to this Section 2(d) regardless of whether you cease to be Retired from the Industry if (i) your termination qualifies as a Mutual Agreement Termination, or (ii) a forfeiture upon your ceasing to be Retired from the Industry would violate applicable law.

(e) Mutual Agreement Termination. If you cease to be an Employee prior to the date that your Stock Units become fully vested and your termination qualifies as a Mutual Agreement Termination, you will continue to vest in your unvested Stock Units pursuant to Section 2(a) above and once vested, you will receive the underlying shares of Common Stock pursuant to the Stock Units that become vested hereunder following the originally contemplated Vesting Date(s).

(f) Other Termination Events. If you cease to be an Employee prior to the date that your Stock Units become fully vested for any reason other than those provided above, you shall cease vesting in your Stock Units effective as of your Termination Dateand any unvested Stock Units immediately shall terminate and be forfeited.

(g) Form and Timing of Settlement. Notwithstanding the foregoing, the Corporation may, in its sole discretion, settle your Stock Units in the form of: (i) a cash payment to the extent settlement in shares of Common Stock (1) is prohibited under local law, (2) would require you or the Corporation to obtain the approval of any governmental and/or regulatory body in your country of residence (and/or country of employment, if different) or (3) is administratively burdensome or (ii) shares of Common Stock, but require you to immediately sell such shares of Common Stock (in which case, the Corporation shall have the authority to issue sales instructions in relation to such shares of Common Stock on your behalf). Also, the Stock Units shall be settled as soon as administratively practicable following the applicable Vesting Date (but in no event later than 60 days following the applicable Vesting Date).

(h) Dividend Equivalents. Upon the payment of any dividend on the shares of Common Stock occurring during the period preceding the settlement of your Stock Units pursuant to these Terms and Conditions, the Corporation shall credit to you an amount in cash equal in value to the dividends that you would have received had you been the actual owner of the number of shares of Common Stock represented by the Stock Units. The payment of any dividend equivalents as provided herein shall be made as soon as administratively practicable following the originally contemplated Vesting Date(s) (but in no event later than 60 days following the applicable Vesting Date).

3. Treatment Upon Change in Control.

(a) General. Except as may be otherwise provided in an agreement executed by the Corporation (and, where applicable, approved by the Corporation’s shareholders) addressing a Change in Control and which does not materially impair your rights under the Stock Units, your Stock Units shall be treated in accordance with the following provisions in the event of a Change in Control.

(b) Conversion of Stock Units. In the event of a Change in Control, the outstanding Stock Units (“Northern Trust Stock Units”) shall be converted into a Replacement Award. Upon a Qualifying Termination, the Replacement Award shall become fully vested and

- 2 -

the acquirer shall issue you shares of acquirer’s common stock in settlement of such Replacement Award as soon as administratively practicable following such Qualifying Termination (but in no event later than 60 days following the Qualifying Termination). For purposes of the foregoing and to the extent possible, the conversion of Northern Trust Stock Units into a Replacement Award shall be effectuated in accordance with the applicable provisions of the Code (and the related Treasury Regulations) and the applicable provisions of the laws of your country of residence and/or country of employment such that the conversion is tax neutral and itself does not trigger a taxable event to you, the Corporation, your Employer or the acquirer.

(c) Cashout of Stock Units. In the event of a Change in Control where the acquirer does not convert Northern Trust Stock Units into a Replacement Award, the Corporation shall fully vest each Northern Trust Stock Unit immediately prior to the Change in Control, and then shall cancel each such vested Northern Trust Stock Unit in exchange for a cash payment equal to the aggregate consideration paid to each shareholder of one (1) share of Common Stock upon the Change in Control. Such cash payment shall be made as soon as administratively practicable following the Change in Control (but in no event later than 60 days following the Change in Control) in such manner and in accordance with such procedures as the Committee may determine in its sole discretion.

4. Legal and Tax Compliance; Cooperation. If you are resident and/or employed outside of the United States, you agree, as a condition of the grant of the Stock Units, to repatriate all payments attributable to the shares of Common Stock and/or cash acquired under the 2017 Plan (including, but not limited to, dividends, dividend equivalents and any proceeds derived from the sale of the shares of Common Stock acquired pursuant to the Stock Units) if required by and in accordance with local foreign exchange rules and regulations in your country of residence (and/or country of employment, if different). In addition, you also agree to take any and all actions, and consent to any and all actions taken by the Corporation and its Subsidiaries, as may be required to allow the Corporation and its Subsidiaries to comply with local laws, rules and regulations in your country of residence (and/or country of employment, if different). Finally, you agree to take any and all actions as may be required to comply with your personal legal and tax obligations under local laws, rules and regulations in your country of residence (and/or country of employment, if different).

5. Age Discrimination Rules. If you are resident and/or employed in a country that is a member of the European Union, the grant of the Stock Units and these Terms and Conditions are intended to comply with the Age Discrimination Rules. To the extent that a court or tribunal of competent jurisdiction determines that any provision of the Terms and Conditions are invalid or unenforceable, in whole or in part, under the Age Discrimination Rules, the Corporation, in its sole discretion, shall have the power and authority to revise or strike such provision to the minimum extent necessary to make it valid and enforceable to the full extent permitted under local law.

6. Withholding of Tax-Related Items.

(a) Regardless of any action the Corporation and/or your Employer take with respect to any or all Tax-Related Items, you acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that the Corporation and your Employer (i) make no representations or undertakings regarding the treatment of any Tax-

- 3 -

Related Items in connection with any aspect of the Stock Units, including the grant of the Stock Units, the vesting of the Stock Units, the subsequent sale of any shares of Common Stock acquired pursuant to the Stock Units and the receipt of any dividends or dividend equivalents and (ii) do not commit to structure the terms of the grant or any aspect of the Stock Units to reduce or eliminate your liability for Tax-Related Items.

(b) Prior to the delivery of shares of Common Stock upon the vesting of your Stock Units, if your country of residence (and/or country of employment, if different) requires withholding of Tax-Related Items, the Corporation shall withhold a sufficient number of whole shares of Common Stock otherwise issuable upon the vesting of the Stock Units that have an aggregate Fair Market Value sufficient to pay the Tax-Related Items required to be withheld with respect to the shares of Common Stock. The cash equivalent of the shares of Common Stock withheld will be used to settle the obligation to withhold the Tax-Related Items. In the event that withholding in shares of Common Stock is prohibited or problematic under applicable law or otherwise may trigger adverse consequences to the Corporation or your Employer, your Employer may withhold the Tax-Related Items required to be withheld with respect to the shares of Common Stock in cash from your regular salary and/or wages or any other amounts payable to you. In the event the withholding requirements are not satisfied through the withholding of shares of Common Stock by the Corporation or through your regular salary and/or wages or other amounts payable to you by your Employer, no shares of Common Stock will be issued to you (or your estate) upon vesting of the Stock Units unless and until satisfactory arrangements (as determined by the Corporation) have been made by you with respect to the payment of any Tax-Related Items that the Corporation or your Employer determines, in its sole discretion, must be withheld or collected with respect to such Stock Units.

(c) By accepting these Stock Units, you expressly consent to the foregoing methods of withholding as provided for hereunder. All other Tax-Related Items related to the Stock Units and any shares of Common Stock delivered in settlement thereof are your sole responsibility.

7. Code Section 409A.

(a) The Stock Units are intended to comply with or be exempt from the requirements of Code Section 409A. The 2017 Plan and these Terms and Conditions shall be administered and interpreted in a manner consistent with this intent. If the Corporation determines that these Terms and Conditions are subject to Code Section 409A and that they do not comply with or are inconsistent with the applicable requirements, the Corporation may, in its sole discretion, and without your consent, amend these Terms and Conditions to cause them to comply with Code Section 409A or be exempt from Code Section 409A.

(b) Notwithstanding any provision of these Terms and Conditions to the contrary, in the event that any settlement or payment of the Stock Units occurs as a result of your termination of employment and the Corporation determines that you are a “specified employee” (within the meaning of Code Section 409A) subject to Code Section 409A at the time of your termination of employment, and provided further that such payment or settlement does not otherwise qualify for an applicable exemption from Code Section 409A, then no such settlement or payment shall be paid to you until the date that is the earlier to occur of: (i) your death, or (ii) six (6) months and one (1) day following your termination of employment.Any portion of the Stock Units where settlement is delayed as a result of the foregoing, which is (i) in whole or in part, settled in cash and (ii) based on

- 4 -

the value of a share of Common Stock, shall be based on the value of a share of Common Stock at the time the Stock Units otherwise would have been settled or paid without application of the delay described in the foregoing sentence.If the Stock Units do not otherwise qualify for an applicable exemption from Code Section 409A, the terms “Retirement,” “terminate,” “termination,” “termination of employment,” and variations thereof as used in these Terms and Conditions are intended to mean a “separation from service” as such term is defined under Code Section 409A.

(c) Although these Terms and Conditions and the payments provided hereunder are intended to be exempt from or to otherwise comply with the requirements of Code Section 409A, the Corporation does not represent or warrant that these Terms and Conditions or the payments provided hereunder will comply with Code Section 409A or any other provisions of federal, state, local, or non-U.S. law. Neither the Corporation, its Subsidiaries, your Employer or their respective directors, officers, employees or advisers shall be liable to you (or any other individual claiming a benefit through you) for any tax, interest, or penalties you may owe as a result of compensation paid under these Terms and Conditions, and the Corporation, its Subsidiaries and your Employer shall have no obligation to indemnify or otherwise protect you from the obligation to pay any taxes pursuant to Code Section 409A.

8. Forfeitures and Recoupment

(a) Recoupment Policy. In addition to these Terms and Conditions, your Stock Units and any shares of Common Stock issued to you pursuant to the Stock Units shall be subject to the provisions of the Northern Trust Corporation Policy on Recoupment, as may be subsequently amended from time to time (the “Policy”).

(b) Delegation of Authority to Corporation. For purposes of the foregoing, you expressly and explicitly authorize the Corporation to issue instructions, on your behalf, to any brokerage firm and/or third party administrator engaged by the Corporation to hold your shares of Common Stock and other amounts acquired pursuant to your Stock Units to re-convey, transfer or otherwise return such shares of Common Stock and/or other amounts to the Corporation upon the Corporation's enforcement of the Policy. To the extent that these Terms and Conditions and the Policy conflict, the terms of the Policy shall prevail.

9. Nontransferability. The Stock Units shall be transferable only by will or the laws of descent and distribution. If you purport to make any transfer of the Stock Units, except as aforesaid, the Stock Units and all rights thereunder shall terminate immediately.

10. Securities Laws. The Stock Units shall not be vested in whole or in part, and the Corporation shall not be obligated to issue any shares of Common Stock subject to the Stock Units, if such issuance would, in the opinion of counsel for the Corporation, violate the Securities Act of 1933 or any other U.S. federal, state or non-U.S. laws having similar requirements as may be in effect at the time. The Stock Units are subject to the further requirement that, if at any time the Board of Directors of the Corporation shall determine in its discretion that the listing or qualification of the shares of Common Stock subject to the Stock Units under any securities exchange requirements or under any applicable law, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of or in connection with the issuance of shares of Common Stock pursuant to the Stock Units, the Stock

- 5 -

Units may not be vested in whole or in part unless such listing, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Corporation.

11. No Right of Continued Employment. The grant of the Stock Units shall not confer upon you any right to continue in the employ of your Employer nor limit in any way the right of your Employer to terminate your employment at any time. You shall have no rights as a shareholder of the Corporation with respect to any shares of Common Stock issuable upon the vesting of the Stock Units until the date of issuance of such shares of Common Stock.

12. Discretionary Nature; No Vested Rights. You acknowledge and agree that the 2017 Plan is discretionary in nature and may be amended, cancelled, or terminated by the Corporation, in its sole discretion, at any time. The grant of the Stock Units under the 2017 Plan is a one-time benefit and does not create any contractual or other right to receive a grant of Stock Units or any other award under the 2017 Plan or other benefits in lieu thereof in the future. Future grants, if any, will be at the sole discretion of the Corporation, including, but not limited to, the form and timing of any grant, the number of shares of Common Stock subject to the grant, and the vesting provisions. Any amendment, modification or termination of the 2017 Plan shall not constitute a change or impairment of the terms and conditions of your employment with your Employer.

13. Extraordinary Benefit. Your participation in the 2017 Plan is voluntary. The value of the Stock Units and any other awards granted under the 2017 Plan is an extraordinary item of compensation outside the scope of your employment (and your employment contract, if any).

Further, if you transfer your residence and/or employment to another country reflected in an Addendum to these Terms and Conditions at the time of transfer, the special terms and conditions for such country will apply to you to the extent the Corporation determines, in its sole discretion, that the application of such special terms and conditions is necessary or advisable in order to comply with local law, rules and regulations or to facilitate the operation and administration of the Stock Units and the 2017 Plan (or the Corporation may establish alternative terms and conditions as may be necessary or advisable to accommodate your transfer). In all circumstances, any applicable Addendum shall constitute part of these Terms and Conditions.

22. Insider Trading. By participating in the 2017 Plan, you expressly agree to comply with the Corporation’s Securities Transactions Policy and Procedures and any other of its policies regarding insider trading or personal account dealing applicable to you. Further, you expressly acknowledge and agree that, depending on the country of residence of you or your broker, or where the shares of Common Stock are listed, you may be subject to insider trading restrictions and/or market abuse laws which may affect your ability to accept, acquire, sell or otherwise dispose of shares of Common Stock, rights to shares of Common Stock (e.g., Stock Units) or rights linked to the value of the shares of Common Stock, during such times you are

considered to have material non-public information, “inside information” or similar types of information regarding the Corporation as defined by laws or regulations in the applicable country. Local insider trading laws and regulations may prohibit the cancellation or amendment of orders you place before you possessed such information. Furthermore, you may be prohibited from (a) disclosing such information to any third party (other than on a “need to know” basis) and (b) “tipping” third parties or causing them otherwise to buy or sell securities (including other employees of the Corporation and its Subsidiaries). Any restriction under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Corporation policies. You expressly acknowledge and agree that it is your responsibility to comply with any applicable restrictions, and you should consult your personal advisor for additional information on any trading restrictions that may apply to you.

Such requirements may include (but are not limited to) requiring you to sign any agreements or undertakings that may be necessary to accomplish the foregoing.

Upon the grant of the Stock Units, you shall be deemed irrevocably to have waived any such entitlement.

26. Important Notices.

(a)    Review Period. You have a minimum of 14 calendar days to consider these Terms and Conditions (measured from the date on which the Corporation provides these Terms and Conditions to you) before accepting the grant of Stock Units (the “Review Period”).

- 11 -

For the sake of clarity, you may accept the grant of the Stock Units and these Terms and Conditions prior to the expiration of the Review Period.

(b)    Attorney Consultation. The Corporation hereby advises you to consult with an attorney before accepting the grant of the Stock Units and these Terms and Conditions.

(c)    Illinois Residents and Illinois-Based Employees Only: Illinois Freedom to Work Act. Notwithstanding anything in these Terms and Conditions to the contrary, if (i) you are a resident of the State of Illinois or if your primary place of work for your Employer is in the State of Illinois, and (ii) your actual or expected annualized rate of earnings exceeds $75,000 per year (as subject to adjustment pursuant to the Illinois Freedom to Work Act), the provisions addressing the treatment of the Stock Units upon your Retirement so long as you remain Retired from the Industry may fall within the meaning of a “Covenant not to compete” as defined in the Illinois Freedom to Work Act. You should be mindful of this potential characterization when considering these Terms and Conditions during the Review Period and consulting with an attorney before accepting the grant of the Stock Units and these Terms and Conditions.

27. Acceptance. By accepting the grant of the Stock Units, you affirmatively and expressly acknowledge that you have read these Terms and Conditions, the Award Notice, the Addendum to these Terms and Conditions (as applicable) and the 2017 Plan, and specifically accept and agree to the provisions therein. You also affirmatively and expressly acknowledge that the Corporation, in its sole discretion, may amend these Terms and Conditions without your consent, either prospectively or retroactively, to the extent that such amendment does not materially impair your rights under the Stock Units, and you agree to be bound by such amendment regardless of whether notice is given to you of such change.

Throughout the notes to the consolidated financial statements, the term “Northern Trust” refers to the Corporation and its subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements, as of and for the periods ended March 31, 2022 and 2021, 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. The accounting and financial reporting policies of Northern Trust conform to U.S. generally accepted accounting principles (GAAP) and reporting practices prescribed for the banking industry. The consolidated statements of income include results of acquired subsidiaries from the dates of acquisition. Certain prior-period balances have been reclassified to conform with the current year’s presentation. During the first quarter of 2022, the Corporation changed the name of the Corporate & Institutional Services (C&IS) segment to “Asset Servicing.” Accordingly, the disclosures herein and all future disclosures regarding the Corporation’s reporting segments filed with, or furnished to, the SEC will refer to this segment as Asset Servicing.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

On January 1, 2022, Northern Trust adopted Accounting Standards Update (ASU) No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contract in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06). ASU 2020-06 simplifies the convertible instrument accounting framework through the elimination of the beneficial conversion and cash conversion accounting models used to account for convertible debt and convertible preferred stock. ASU 2020-06 also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions in Accounting Standards Codification 815—Derivatives and Hedging. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. Upon adoption of ASU 2020-06, there was no significant impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.

On January 1, 2022, Northern Trust adopted ASU No. 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” (ASU 2021-10). ASU 2021-10 requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy to other accounting guidance within Topic 958, Not-for-Profit Entities, or International Accounting Standards 20, Accounting for Government Grants and Disclosure of Government Assistance. Upon adoption of ASU 2021-10, there was no significant impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair Value Hierarchy. The following describes the hierarchy of valuation inputs (Levels 1, 2, and 3) used to measure fair value and the primary valuation methodologies used by Northern Trust for financial instruments measured at fair value on a recurring basis. Observable inputs reflect market data obtained from sources independent of the reporting entity; unobservable inputs reflect the entity’s own assumptions about how market participants would value an asset or liability based on the best information available. GAAP requires an entity measuring fair value to maximize the use of observable inputs and minimize the use of unobservable inputs and establishes a fair value hierarchy of inputs. Financial instruments are categorized within the hierarchy based on the lowest level input that is significant to their valuation. No transfers into or out of Level 3 occurred during the three months ended March 31, 2022 or the year ended December 31, 2021.

Level 1 — Quoted, active market prices for identical assets or liabilities.

Northern Trust’s Level 1 assets are comprised of available for sale (AFS) investments in U.S. Treasury securities.

Level 2 — Observable inputs other than Level 1 prices, such as quoted active market prices for similar assets or liabilities, quoted prices for identical or similar assets in inactive markets, and model-derived valuations in which all significant inputs are observable in active markets.

Northern Trust’s Level 2 assets include AFS and trading account debt securities, the fair values of which are determined predominantly by external pricing vendors. Prices received from vendors are compared to other vendor and third-party prices. If a security price obtained from a pricing vendor is determined to exceed predetermined tolerance levels that are assigned based on an asset type’s characteristics, the exception is researched and, if the price is not able to be validated, an alternate pricing

vendor is utilized, consistent with Northern Trust’s pricing source hierarchy. As of March 31, 2022, Northern Trust’s AFS debt securities portfolio included 2,576 Level 2 debt securities with an aggregate market value of $34.3 billion. All 2,576 debt securities were valued by external pricing vendors. As of December 31, 2021, Northern Trust’s AFS debt securities portfolio included 2,547 Level 2 debt securities with an aggregate market value of $35.6 billion. All 2,547 debt securities were valued by external pricing vendors. Trading account debt securities, which totaled $0.4 million and $0.3 million as of March 31, 2022 and December 31, 2021, respectively, were all valued using external pricing vendors.

Level 2 assets and liabilities also include derivative contracts which are valued internally using widely accepted income-based models that incorporate inputs readily observable in actively quoted markets and reflect the contractual terms of the contracts. Observable inputs include foreign exchange rates and interest rates for foreign exchange contracts; credit spreads, default probabilities, and recovery rates for credit default swap contracts; interest rates for interest rate swap contracts and forward contracts; and interest rates and volatility inputs for interest rate option contracts. Northern Trust evaluates the impact of counterparty credit risk and its own credit risk on the valuation of its derivative instruments. Factors considered include the likelihood of default by Northern Trust and its counterparties, the remaining maturities of the instruments, net exposures after giving effect to master netting arrangements or similar agreements, available collateral, and other credit enhancements in determining the appropriate fair value of derivative instruments. The resulting valuation adjustments have not been considered material.

Level 3 — Valuation techniques in which one or more significant inputs are unobservable in the marketplace.

Northern Trust’s Level 3 liabilities consist of swaps that Northern Trust entered into with the purchaser of 1.1 million and 1.0 million shares of Visa Inc. Class B common stock (Visa Class B common shares) previously held by Northern Trust and sold in June 2016 and 2015, respectively. Pursuant to the swaps, Northern Trust retains the risks associated with the ultimate conversion of the Visa Class B common shares into shares of Visa Inc. Class A common stock (Visa Class A common shares), such that the counterparty will be compensated for any dilutive adjustments to the conversion ratio and Northern Trust will be compensated for any anti-dilutive adjustments to the ratio. The swaps also require periodic payments from Northern Trust to the counterparty calculated by reference to the market price of Visa Class A common shares and a fixed rate of interest. The fair value of the swaps is determined using a discounted cash flow methodology. The significant unobservable inputs used in the fair value measurement are Northern Trust’s own assumptions about estimated changes in the conversion rate of the Visa Class B common shares into Visa Class A common shares, the date on which such conversion is expected to occur and the estimated growth rate of the Visa Class A common share price. See “Visa Class B Common Shares” under Note 21 — Commitments and Contingent Liabilities for further information.

Northern Trust believes its valuation methods for its assets and liabilities carried at fair value are appropriate; however, the use of different methodologies or assumptions, particularly as applied to Level 3 assets and liabilities, could have a material effect on the computation of their estimated fair values.

The following table presents the fair values of Northern Trust’s Level 3 liabilities as of March 31, 2022 and December 31, 2021, as well as the valuation techniques, significant unobservable inputs, and quantitative information used to develop significant unobservable inputs for such liabilities as of such dates.

The following table presents the changes in Level 3 liabilities for the three months ended March 31, 2022 and 2021.

Carrying values of assets and liabilities that are not measured at fair value on a recurring basis may be adjusted to fair value in periods subsequent to their initial recognition, for example, to record an impairment of an asset. GAAP requires entities to separately disclose these subsequent fair value measurements and to classify them under the fair value hierarchy.

Assets measured at fair value on a nonrecurring basis at March 31, 2022 and December 31, 2021, all of which were categorized as Level 3 under the fair value hierarchy, were comprised of nonaccrual loans whose values were based on real estate and other available collateral, and of other real estate owned (OREO) properties.

Fair values of real estate loan collateral were estimated using a market approach typically supported by third-party valuations and property-specific fees and taxes. The fair values of real estate loan collateral were subject to adjustments to reflect management’s judgment as to realizable value and consisted of discount factors ranging from 15.0% to 20.0% with a weighted average based on fair values of 16.3% and 15.4% as of March 31, 2022 and December 31, 2021, respectively. Other loan

collateral, which typically consists of accounts receivable, inventory and equipment, is valued using a market approach adjusted for asset-specific characteristics and in limited instances third-party valuations are used. OREO assets are carried at the lower of cost or fair value less estimated costs to sell, with fair value typically based on third-party appraisals.

Collateral-based nonaccrual loans that have been adjusted to fair value totaled $13.3 million and $15.0 million at March 31, 2022 and December 31, 2021, respectively.

The following table presents the fair values of Northern Trust’s Level 3 assets that were measured at fair value on a nonrecurring basis as of March 31, 2022 and December 31, 2021, as well as the valuation technique, significant unobservable inputs and quantitative information used to develop the significant unobservable inputs for such assets as of such dates.

As of March 31, 2022, 2,196 AFS debt securities with a combined fair value of $26.0 billion were in an unrealized loss position, with their unrealized losses totaling $1,157.7 million. As of March 31, 2022, unrealized losses related to AFS debt securities of $475.9 million and $256.6 million related to government-sponsored agency securities and obligations of states and political subdivisions, respectively, are primarily attributable to changes in market interest rates and credit spreads since their purchase.

As of December 31, 2021, 1,233 AFS debt securities with a combined fair value of $18.7 billion were in an unrealized loss position, with their unrealized losses totaling $248.6 million. As of December 31, 2021, unrealized losses related to AFS debt securities of $110.2 million related to government-sponsored agency securities, which are primarily attributable to changes in market interest rates and credit spreads since their purchase.

12% and 14% of the AFS corporate debt securities portfolio were backed by guarantees provided by U.S. and non-U.S. governmental entities as of March 31, 2022 and December 31, 2021, respectively. The remaining unrealized losses on Northern Trust’s AFS debt securities portfolio as of March 31, 2022 and December 31, 2021 are attributable to changes in overall market interest rates or credit spreads.

As of March 31, 2022, Northern Trust did not intend to sell any AFS debt securities in an unrealized loss position and it was more likely than not that Northern Trust would not be required to sell any such investment before the recovery of its amortized cost basis, which may be maturity.

AFS debt securities impairment reviews are conducted quarterly to identify and evaluate securities that have indications of possible credit losses. A determination as to whether a security’s decline in market value is related to credit impairment takes into consideration numerous factors and the relative significance of any single factor can vary by security. Factors Northern Trust considers in determining whether impairment is credit-related include, but are not limited to, the severity of the impairment; the cause of the impairment and the financial condition and near-term prospects of the issuer; activity in the market of the issuer, which may indicate adverse credit conditions; Northern Trust’s intent regarding the sale of the security as of the balance sheet date; and the likelihood that Northern Trust will not be required to sell the security for a period of time sufficient to allow for the recovery of the security’s amortized cost basis. For each security meeting the requirements of Northern Trust’s internal screening process, an extensive review is conducted to determine if a credit loss has occurred.

There was a $0.4 million provision for credit losses for corporate debt AFS securities for the three months ended March 31, 2022, while there was no provision for credit losses for corporate debt AFS securities for the three months ended March 31, 2021. There was a $0.4 million allowance for credit losses for corporate debt AFS securities as of March 31, 2022 and no allowance for credit losses for corporate debt AFS securities as of December 31, 2021. The process for identifying credit losses for corporate debt AFS securities is based on the best estimate of cash flows to be collected from the security, discounted using the security’s effective interest rate. If the present value of the expected cash flows is found to be less than the current amortized cost of the security, an allowance for credit losses is generally recorded equal to the difference between the two amounts, limited to the amount the amortized cost basis exceeds the fair value of the security. For additional information, please refer to Note 7 — Allowance for Credit Losses.

Held to Maturity Debt Securities. The following tables provide the amortized cost and fair values at March 31, 2022 and December 31, 2021, and remaining maturities of held to maturity (HTM) debt securities at March 31, 2022.

HTM debt securities consist of securities that management intends to, and Northern Trust has the ability to, hold until maturity. During the three months ended March 31, 2022 and 2021, no securities were transferred from AFS to HTM. Upon transfer of a debt security from the AFS to HTM classification, the amortized cost is reset to fair value. Any net unrealized gain or loss at the date of transfer will remain in Accumulated Other Comprehensive Income (Loss) (AOCI) and be amortized into net interest income over the remaining life of the securities using the effective interest method. The amortization of amounts retained in AOCI will offset the effect on interest income of the amortization of the premium or discount resulting from transferring the securities at fair value.

Credit Quality Indicators. The following table provides the amortized cost of HTM debt securities by credit rating.

Banking and Thrift, Other Disclosures [Abstract]

Securities Sold Under Agreements to Repurchase

Securities Sold Under Agreements to RepurchaseSecurities sold under agreements to repurchase are accounted for as collateralized financings and recorded at the amounts at which the securities were sold plus accrued interest. To minimize any potential credit risk associated with these transactions, the fair value of the securities sold is monitored, limits are set on exposure with counterparties, and the financial condition of counterparties is regularly assessed. Securities sold under agreements to repurchase are either directly held by, or pledged to the counterparty until the repurchase. Northern Trust nets securities sold under repurchase agreements against those purchased under resale agreements when the Fixed Income Clearing Corporation (FICC) is the counterparty.

The following table provides information regarding repurchase agreements that are accounted for as secured borrowings as of March 31, 2022 and December 31, 2021.

Residential real estate loans consist of traditional first lien mortgages and equity credit lines that generally require a loan-to-collateral value of no more than 65% to 80% at inception. Northern Trust’s equity credit line products generally have draw periods of up to 10 years and a balloon payment of any outstanding balance is due at maturity. Payments are interest-only with variable interest rates. Northern Trust does not offer equity credit lines that include an option to convert the outstanding balance to an amortizing payment loan. As of March 31, 2022 and December 31, 2021, equity credit lines totaled $233.5 million and $258.2 million, respectively, and equity credit lines for which first liens were held by Northern Trust represented 97% of the total equity credit lines as of both March 31, 2022 and December 31, 2021.

Included within the non-U.S., commercial-other and personal-other classes are short-duration advances primarily related to the processing of custodied client investments, totaling $1.9 billion at March 31, 2022 and $1.6 billion at December 31, 2021, respectively. Demand deposit overdrafts reclassified as loan balances totaled $9.7 million and $8.0 million at March 31, 2022 and December 31, 2021, respectively. Loans classified as held for sale, which totaled $10.8 million and $12.3 million at March 31, 2022 and December 31, 2021, respectively, related to the decision to exit a non-strategic loan portfolio. Loans classified as held for sale are recorded at the lower of cost or fair value.

As of March 31, 2022 and December 31, 2021, there were no leases classified as held for sale.

Paycheck Protection Program. In response to the COVID-19 pandemic, Northern Trust became a lender under the Paycheck Protection Program, as amended (PPP), which was created by the Coronavirus Aid, Relief, and Economic Security (CARES) Act and is administered by the U.S. Small Business Administration (SBA). Loans issued under the PPP are funded by Northern Trust directly to participating borrowers. The PPP loans are guaranteed by the SBA and borrowers are eligible to apply for PPP loan forgiveness for up to the full principal amount and accrued interest of the PPP loan.

To the extent a borrower uses PPP loan proceeds to cover eligible costs and has met all other SBA loan forgiveness requirements, the SBA will determine loan forgiveness under the CARES Act and will pay to Northern Trust the eligible PPP loan forgiven amount, which will be credited to the borrower’s loan to repay or pay down the PPP loan. The SBA forgiveness portal opened on August 10, 2020 and Northern Trust’s vendor portal opened on September 11, 2020 to begin processing the PPP loan forgiveness applications. When Northern Trust submits forgiveness applications to the SBA, the SBA has at least 90 days to respond as to the approval or denial of such application. 143 and 1,301 loans were forgiven through the PPP loan forgiveness process which resulted in $39.2 million and $231.5 million of loan principal and interest being forgiven during the three months ended March 31, 2022 and the year ended December 31, 2021, respectively.

As of March 31, 2022, Northern Trust had 73 outstanding loans totaling $16.3 million under the PPP in its commercial and institutional portfolio with an average loan balance of $0.2 million.

Northern Trust accounts for loans originated under the PPP as loan receivables in accordance with Accounting Standards Codification (ASC) 310 and recognizes such loans at the principal amount less the net amount of loan origination fees. PPP loans are reported in Total Loans and Leases on the consolidated balance sheets.

The SBA provides a 100% guarantee on PPP loans covering principal and interest. Northern Trust considers the risk mitigating effects of these guarantees, and accounts for them as a credit enhancement embedded in the contract. As a result, no allowance for credit losses is measured for Northern Trust’s exposure under the PPP.

Credit Quality Indicators. Credit quality indicators are statistics, measurements or other metrics that provide information regarding the relative credit risk of loans and leases. Northern Trust utilizes a variety of credit quality indicators to assess the credit risk of loans and leases at the segment, class, and individual credit exposure levels.

As part of its credit process, Northern Trust utilizes an internal borrower risk rating system to support identification, approval, and monitoring of credit risk. Borrower risk ratings are used in credit underwriting and management reporting. Risk ratings are used for ranking the credit risk of borrowers and the probability of their default. Each borrower is rated using one of a number of ratings models, which consider both quantitative and qualitative factors. The ratings models vary among classes of loans and leases in order to capture the unique risk characteristics inherent within each particular type of credit exposure. Provided below are the more significant performance indicator attributes considered within Northern Trust’s borrower rating models, by loan and lease class.

•Commercial and Institutional: leverage, profit margin, liquidity, asset size and capital levels;

•Commercial Real Estate: debt service coverage, loan-to-value ratio, leasing status and guarantor support;

•Lease Financing and Commercial-Other: leverage, profit margin, liquidity, asset size and capital levels;

•Non-U.S.: leverage, profit margin, liquidity, return on assets and capital levels;

•Residential Real Estate: payment history, credit bureau scores and loan-to-value ratio;

•Private Client: cash-flow-to-debt and net worth ratios, leverage and liquidity; and

•Personal-Other: cash-flow-to-debt and net worth ratios.

While the criteria vary by model, the objective is for the borrower ratings to be consistent in both the measurement and ranking of risk. Each model is calibrated to a master rating scale to support this consistency. Ratings for borrowers not in default range from “1” for the strongest credits to “7” for the weakest non-defaulted credits. Ratings of “8” or “9” are used for defaulted borrowers. Borrower risk ratings are monitored and are revised when events or circumstances indicate a change is required. Risk ratings are generally validated at least annually.

Loan and lease segment and class balances as of March 31, 2022 and December 31, 2021 are provided in the following table, segregated by borrower ratings into “1 to 3,” “4 to 5” and “6 to 9” (watch list and nonaccrual status) categories by year of origination at amortized cost basis. Loans that are held for investment are reported at the principal amount outstanding, net of unearned income.

Loans and leases in the “1 to 3” category are expected to exhibit minimal to modest probabilities of default and are characterized by borrowers having the strongest financial qualities, including above average financial flexibility, cash flows and capital levels. Borrowers assigned these ratings are anticipated to experience very little to moderate financial pressure in adverse down-cycle scenarios. As a result of these characteristics, borrowers within this category exhibit a minimal to modest likelihood of loss.

Loans and leases in the “4 to 5” category are expected to exhibit moderate to acceptable probabilities of default and are characterized by borrowers with less financial flexibility than those in the “1 to 3” category. Cash flows and capital levels are generally sufficient to allow for borrowers to meet current requirements, but have fewer financial resources to manage through economic downturns. As a result of these characteristics, borrowers within this category exhibit a moderate likelihood of loss.

Loans and leases in the watch list category have elevated credit risk profiles that are monitored through internal watch lists, and consist of credits with borrower ratings of “6 to 9.” These credits, which include all nonaccrual credits, are expected to exhibit minimally acceptable probabilities of default, elevated risk of default, or are currently in default. Borrowers associated with these risk profiles that are not currently in default have limited financial flexibility. Cash flows and capital levels range from acceptable to potentially insufficient to meet current requirements, particularly in adverse down cycle scenarios. As a result of these characteristics, borrowers in this category exhibit an elevated to probable likelihood of loss.

Past Due Status. Past due status is based on the length of time from the contractual due date a principal or interest payment has been past due. For disclosure purposes, loans and leases that are 29 days past due or less are reported as current.

The following table provides balances and delinquency status of accrual and nonaccrual loans and leases by segment and class, as well as the other real estate owned and nonaccrual asset balances, as of March 31, 2022 and December 31, 2021.

Interest income that would have been recorded for nonaccrual loans and leases in accordance with their original terms was $1.1 million and $0.9 million for the three months ended March 31, 2022 and 2021, respectively.

Collateral Dependent Financial Assets. A financial asset is collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. Most of Northern Trust’s collateral dependent credit exposure relates to its residential real estate portfolio for which the collateral is usually the underlying real estate property. For collateral dependent financial assets, it is Northern Trust’s policy to reserve or charge-off the difference between the amortized cost basis of the loan and the value of the collateral. The collateral dependent financial asset balance as of March 31, 2022 was immaterial to Northern Trust’s financial statements.

Recognition of Income. Interest income on loans and leases is recorded on an accrual basis unless, in the opinion of management, there is a question as to the ability of the debtor to meet the terms of the loan agreement, or interest or principal is more than 90 days contractually past due and the loan is not well-secured and in the process of collection. Loans meeting such criteria are classified as nonaccrual and interest income is recorded on a cash basis. At the time a loan is determined to be nonaccrual, interest accrued but not collected is reversed against interest income in the current period. Interest collected on nonaccrual loans is applied to principal unless, in the opinion of management, collectability of principal is not in doubt. Management’s assessment of the indicators of loan and lease collectability, and its policies relative to the recognition of interest income, including the suspension and subsequent resumption of income recognition, do not meaningfully vary between loan and lease classes. Nonaccrual loans are returned to accrual status when factors indicating doubtful collectability no longer exist. Factors considered in returning a loan to accrual status are consistent across all classes of loans and leases and, in accordance with regulatory guidance, relate primarily to expected payment performance. Loans are eligible to be returned to accrual status when: (i) no principal or interest that is due is unpaid and repayment of the remaining contractual principal and interest is expected or (ii) the loan has otherwise become well-secured (possessing realizable value sufficient to discharge the debt, including accrued interest, in full) and is in the process of collection (through action reasonably expected to result in debt repayment or restoration to a current status in the near future). A loan that has not been brought fully current may be restored to accrual status provided there has been a sustained period of repayment performance (generally a minimum of six payment periods) by the borrower in accordance with the contractual terms, and Northern Trust is reasonably assured of repayment within a reasonable period of time. Additionally, a loan that has been formally restructured so as to be reasonably assured of repayment and performance according to its modified terms may be returned to accrual status, provided there was a well-documented credit evaluation of the borrower’s financial condition and prospects of repayment under the revised terms and there has been a sustained period of repayment performance (generally a minimum of six payment periods) under the revised terms.

Nonaccrual Loans and Troubled Debt Restructurings (TDRs). A loan that has been modified as a concession by Northern Trust or a bankruptcy court resulting from the debtor’s financial difficulties is referred to as a troubled debt restructuring (TDR). All TDRs are reported starting in the calendar year of their restructuring. In subsequent years, a TDR may cease being reported if the loan was modified at a market rate and has performed according to the modified terms for at least six payment

periods. A loan that has been modified at a below market rate will return to accrual status if it satisfies the six-payment-period performance requirement.

The expected credit loss is measured based upon the present value of expected future cash flows, discounted at the effective interest rate based on the original contractual rate. If a loan’s contractual interest rate varies based on subsequent changes in an independent factor, such as an index or rate, the loan’s effective interest rate is calculated based on the factor as it changes over the life of the loan. Northern Trust elected not to project changes in the factor for purposes of estimating expected future cash flows. Further, Northern Trust elected not to adjust the effective interest rate for prepayments. If the loan is collateral dependent, the expected loss is measured based on the fair value of the collateral at the reporting date.

If the loan valuation is less than the recorded value of the loan, either an allowance is established or a charge-off is recorded for the difference. Smaller balance (individually less than $1 million) homogeneous loans are collectively evaluated. Northern Trust’s accounting policies for material nonaccrual loans is consistent across all classes of loans and leases.

All loans and leases with TDR modifications are evaluated for additional expected credit losses. The nature and extent of further deterioration in credit quality, including a subsequent default, is considered in the determination of an appropriate level of allowance for credit losses.

Included within nonaccrual loans were $46.1 million and $76.7 million of nonaccrual TDRs, and $18.3 million and $16.5 million of accrual TDRs as of March 31, 2022 and December 31, 2021, respectively.

There were $0.2 million of aggregate undrawn loan commitments and standby letters of credit at both March 31, 2022 and December 31, 2021 issued to borrowers with TDR modifications of loans.

The following table provides, by segment and class, the number of TDR modifications of loans and leases during the three months ended March 31, 2022 and 2021, and the recorded investments and unpaid principal balances as of March 31, 2022 and 2021.

TDR modifications involve extensions of term, deferrals of principal, interest rate concessions, and other modifications. Other modifications typically reflect other nonstandard terms which Northern Trust would not offer in non-troubled situations.

During the three months ended March 31, 2022, the TDR loan modifications within residential real estate were deferred principal, interest rate concession, and an extension of term. During the three months ended March 31, 2022, the TDR modification of loans within commercial and institutional was an other modification.

During the three months ended March 31, 2021, the TDR modification of loans within commercial and institutional, residential real estate and commercial real estate was deferred principal.

There were no residential real estate loan TDR modifications during the twelve months ended December 31, 2021, which subsequently had a payment default during the three months ended March 31, 2022.

There was one residential real estate loan TDR modification during the twelve months ended December 31, 2020, which subsequently had a payment default during the three months ended March 31, 2021. The total recorded investment for this loan was approximately $5.5 million and the unpaid principal balance for this loan was approximately $5.5 million.

Northern Trust may obtain physical possession of real estate via foreclosure on an in-substance repossession. As of March 31, 2022, Northern Trust held foreclosed real estate properties with a carrying value of $0.2 million as a result of obtaining physical possession. In addition, as of March 31, 2022, Northern Trust had loans with a carrying value of $1.7 million for which formal foreclosure proceedings were in process.

TDR Relief — COVID-19. Due to the economic environment arising from the COVID-19 pandemic, there have been two forms of relief provided for classifying loans as TDRs: the Interagency Guidance (as defined below) and the CARES Act.

Various banking regulators, including the Board of Governors of the Federal Reserve (Federal Reserve Board), the Federal Deposit Insurance Corporation (FDIC), the National Credit Union Administration, the Office of the Comptroller of the Currency, and the Consumer Financial Protection Bureau, issued guidance in the April 7, 2020 Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (revised) on loan modification treatment (Interagency Guidance) pursuant to which financial institutions can apply ASC 310-40 Receivables – Troubled Debt Restructurings by Creditors. In accordance with the Interagency Guidance, a loan modification is not considered a TDR if: (a) the modification is related to COVID-19; (b) the borrower had been current (not more than 29 days past due) when the modification program was implemented; (c) and the modification includes payment deferrals for not more than 6 months.

Under section 4013 of the CARES Act, relief provided to lenders exempting certain loan modifications which would otherwise be classified as TDRs from such classification applies for loans that were not more than 30 days past due as of December 31, 2019. The TDR relief under the CARES Act applies to COVID-19-related modifications that were made from March 1, 2020 until the earlier of (a) January 1, 2022 or (b) 60 days from the date the COVID-19 national emergency officially ends.

Financial institutions may account for eligible loan modifications under the Interagency Guidance and/or the CARES Act. Northern Trust elected to apply both the CARES Act and the Interagency Guidance, as applicable, in providing borrowers with loan modification relief in response to the COVID-19 pandemic. All other types of modifications which do not meet the CARES Act or Interagency Guidance requirements continue to be governed by existing regulations and accounting policies.

The following provides the number of total COVID-19-related loan modifications including the loan volume and deferred principal and interest balances as of March 31, 2022 and December 31, 2021, for which Northern Trust applied an exemption from TDR classification that are in active deferral (loans currently in the deferral period) or completed deferral (loans that returned to their regular payment schedule). As of March 31, 2022, there were no COVID-19-related loan modifications in active deferral status. As of December 31, 2021, there were three residential real estate COVID-19-related loan modifications in active deferral status which totaled $2.0 million, with immaterial deferred principal and interest.

Northern Trust continues to accrue and recognize interest income during the loan deferral period, and hence has not moved these loans to nonaccrual or reported them as past due. Further, these loan balances continue to be assessed on a collective basis for purposes of measuring an allowance for expected credit losses. While these loans are under the COVID-19 loan modification program, this may delay the recognition of nonaccruals and charge-offs. Loans which have exited the COVID-19 loan modification program may be placed on nonaccrual status or charged-off if borrowers were unable to resume their regular payment schedule.

During the period ended March 31, 2022, 38 loans with an aggregate principal amount of $112.9 million that had been granted payment deferrals were paid off. As of March 31, 2022, less than 3% of loans that had been granted payment deferrals were either past due or in nonaccrual status.

Allowance for Credit Losses

Allowance for Credit Losses

Allowance and Provision for Credit Losses. The allowance for credit losses—which represents management’s best estimate of lifetime expected credit losses related to various portfolios subject to credit risk, off-balance-sheet credit exposures, and specific borrower relationships—is determined by management through a disciplined credit review process. Northern Trust measures expected credit losses of financial assets with similar risk characteristics on a collective basis. A financial asset is measured individually if it does not share similar risk characteristics with other financial assets and the related allowance is determined through an individual evaluation.

Management’s estimates utilized in establishing an appropriate level of allowance for credit losses are not dependent on any single assumption. In determining an appropriate allowance level, management evaluates numerous variables, many of which are interrelated or dependent on other assumptions and estimates, and takes into consideration past events, current conditions and reasonable and supportable forecasts.

The results of the credit reserve estimation methodology are reviewed quarterly by Northern Trust’s Credit Loss Reserve Committee, which receives input from Credit Risk Management, Treasury, Corporate Finance, the Economic Research group, and each of Northern Trust’s business units. The Credit Loss Reserve Committee determines the probability weights applied to each forecast approved by Northern Trust’s Macroeconomic Scenario Development Committee, and also reviews and approves qualitative adjustments to the collective allowance in line with Northern Trust’s qualitative adjustment framework.

The following table provides information regarding changes in the total allowance for credit losses during the three months ended March 31, 2022 and 2021.

The portion of the allowance assigned to loans and leases, HTM debt securities, and other financial assets is presented as a contra asset in Allowance for Credit Losses on the consolidated balance sheets. The portion of the allowance assigned to undrawn loan commitments and standby letters of credit is reported in Other Liabilities on the consolidated balance sheets. For credit exposure and the associated allowance related to fee receivables, please refer to Note 14 — Revenue from Contracts with Clients. For information related to the allowance for AFS debt securities, please refer to Note 4 — Securities. For all other financial assets recognized at amortized cost, which include Cash and Due from Banks, Other Central Bank Deposits, Interest Bearing Deposits with Banks, and Other Assets, please refer to the Allowance for Other Financial Assets section within this footnote.

The Provision for Credit Losses on the consolidated statements of income represents the change in the Allowance for Credit Losses on the consolidated balance sheets and is the charge to current period earnings. It represents the amount needed to maintain the Allowance for Credit Losses on the consolidated balance sheets at an appropriate level to absorb lifetime expected credit losses related to financial assets in scope. Actual losses may vary from current estimates and the amount of the Provision for Credit Losses may be either greater or less than actual net charge-offs.

There was a $2.0 million provision in the current quarter, as compared to a $30.0 million release of credit reserves in the prior-year quarter. The provision for credit losses, excluding available for sale debt securities, was a provision of $1.6 million in the current quarter. There were net recoveries of $3.2 million during the three months ended March 31, 2022, as compared to net recoveries of $0.9 million for the three months ended March 31, 2021. For further detail, please see the Allowance for the Loan and Lease Portfolio and the Allowance for Held to Maturity Debt Securities Portfolio sections below.

Forecasting and Reversion. Estimating expected lifetime credit losses requires the consideration of the effect of future economic conditions. Northern Trust employs multiple scenarios over a reasonable and supportable period (currently two years) to project future conditions. Management determines the probability weights assigned to each scenario at each quarter-end. Key variables determined to be relevant for projecting credit losses on the portfolios in scope include macroeconomic factors, such as corporate profits, unemployment, and real estate price indices, as well as financial market factors such as equity prices, volatility, and credit spreads. For periods beyond the reasonable and supportable period, Northern Trust reverts to its own historical loss experiences on a straight-line basis over four quarters. For the current quarter, the primary forecast, consistent with Northern Trust’s economic outlook publications, continues to reflect an economy recovering from the challenges of COVID-19 and returning to normal. The positive effects of steady growth and falling unemployment rates are partially diminished by the impact of higher inflation, volatility, interest rates and geopolitical events. An alternative scenario is also considered, which reflects a recession that incorporates the experiences of a wider set of historical economic cycles.

Contractual Term. Northern Trust estimates expected credit losses over the contractual term of the financial assets adjusted for prepayments, unless prepayments are not relevant to specific portfolios or sub-portfolios. Extension and renewal options are typically not considered since it is not Northern Trust’s practice to enter into arrangements where the borrower has the unconditional option to renew, or a conditional extension option whereby the conditions are beyond Northern Trust’s control.

The decrease to the allowance for loans and leases of $2.1 million for the three months ended March 31, 2022 was primarily due to a decrease in the reserve evaluated on a collective basis, driven by continued improvements in credit quality, mainly within the commercial real estate portfolio, and partially offset by the impact of worsening projected economic conditions. The decrease in the collective basis reserve was diminished by an increase to the reserve evaluated on an individual basis for two individual commercial borrowers. The increase to the allowance for undrawn loan commitments and standby letters of credit of $3.4 million for the three months ended March 31, 2022 was primarily due to worsening projected economic conditions and an increase in potential exposure.

Allowance Related to Credit Exposure Evaluated on a Collective Basis. Expected credit losses are measured on a collective basis as long as the financial assets included in the respective pool share similar risk characteristics. If financial assets are deemed to not share similar risk characteristics, an individual assessment is warranted.

The allowance estimation methodology for the collective assessment is primarily based on internally developed loss data specific to the Northern Trust financial asset portfolio from a historical observation period that includes both expansionary and

recessionary periods. The estimation methodology and the related qualitative adjustment framework segregate the loan and lease portfolio into homogenous segments based on similar risk characteristics or risk monitoring methods.

Northern Trust utilizes a quantitative probability of default/loss given default approach for the calculation of its credit allowance on a collective basis. For each of the different parameters, specific credit models for the individual loan segments were developed. For each segment, the probability of default and the loss given default are applied to the exposure at default for each projected quarter to determine the quantitative component of the allowance. The quantitative allowance is then reviewed within the qualitative adjustment framework, through which management applies judgment by assessing internal risk factors, potential limitations in the quantitative methodology, and environmental factors that are not fully contemplated in the forecast to compute an adjustment to the quantitative allowance for each segment of the loan portfolio.

Allowance Related to Credit Exposure Evaluated on an Individual Basis. The allowance is determined through an individual evaluation of loans, leases, and lending-related commitments that have defaulted, generally those with Borrower Ratings of 8 and 9, that is based on expected future cash flows, the value of collateral, and other factors that may impact the borrower’s ability to pay. For defaulted loans for which the amount of allowance, if any, is determined based on the value of the underlying real estate collateral, third-party appraisals are typically obtained and utilized by management. These appraisals are generally less than twelve months old and are subject to adjustments to reflect management’s judgment as to the realizable value of the collateral.

The following table provides information regarding the recorded investments in loans and leases and the allowance for credit losses for loans and leases and undrawn loan commitments and standby letters of credit by segment as of March 31, 2022 and December 31, 2021.

Northern Trust analyzes its exposure to credit losses from both on-balance-sheet and off-balance-sheet activity using a consistent methodology for the quantitative framework as well as the qualitative framework. For purposes of estimating the allowance for credit losses for undrawn loan commitments and standby letters of credit, the exposure at default includes an estimated drawdown of unused credit based on credit utilization factors, resulting in a proportionate amount of expected credit losses.

Allowance for Held to Maturity Debt Securities Portfolio. The following table provides information regarding changes in the total allowance for credit losses for HTM debt securities during the three months ended March 31, 2022 and 2021.

HTM debt securities classified as U.S. government, government sponsored agency, and certain securities classified as obligations of states and political subdivisions are considered to be guarantees of the U.S. government or an agency of the U.S. government and therefore an allowance for credit losses is not estimated for such investments as the expected probability of non-payment of the amortized cost basis is zero.

HTM debt securities classified as other asset-backed represent pools of underlying receivables from which the cash flows are used to pay the bonds that vary in seniority. Utilizing a qualitative estimation approach, the allowance for other asset-backed securities is assessed by evaluating underlying pool performance based on delinquency rates and available credit support.

HTM debt securities classified as other relates to investments purchased by Northern Trust to fulfill its obligations under the Community Reinvestment Act (CRA). Northern Trust fulfills its obligations under the CRA by making qualified investments for purposes of supporting institutions and programs that benefit low-to-moderate income communities within Northern Trust’s market area. The allowance for CRA investments is assessed using a qualitative estimation approach primarily based on internal historical performance experience and default history of the underlying CRA portfolios to determine a quantitative component of the allowance.

The allowance estimation methodology for all other HTM debt securities is developed using a combination of external and internal data. The estimation methodology groups securities with shared characteristics for which the probability of default and the loss given default are applied to the total exposure at default to determine a quantitative component of the allowance.

The increase in the allowance attributable to HTM debt securities was due to an increase in the reserve evaluated on a collective basis driven by model enhancements and related macroeconomic factors.

Allowance for Other Financial Assets. The allowance for Other Financial Assets consists of the allowance for Due from Banks, Other Central Bank Deposits, Interest Bearing Deposits with Banks, and Other Assets. The Other Assets category includes other miscellaneous credit exposures reported in Other Assets on the consolidated balance sheets. The allowance estimation methodology for Other Financial Assets primarily utilizes a similar approach as used for the HTM debt securities portfolio. It consists of a combination of externally and internally developed loss data, adjusted for the appropriate contractual term. Northern Trust’s portfolio of Other Financial Assets is composed mostly of institutions within the “1 to 3” internal borrower rating category and is expected to exhibit minimal to modest likelihood of loss. The allowance for credit losses related to Other Financial Assets was $1.1 million and $1.0 million as of March 31, 2022 and December 31, 2021, respectively.

Accrued Interest. Accrued interest balances are reported within Other Assets on the consolidated balance sheets. Northern Trust elected not to measure an allowance for credit losses for accrued interest receivables related to its loan and securities portfolio as its policy is to write-off uncollectible accrued interest receivable balances in a timely manner. Accrued interest is written off by reversing interest income during the quarter the financial asset is moved from an accrual to a nonaccrual status.

The following table provides the amount of accrued interest excluded from the amortized cost basis of the following portfolios.

Segment Reporting [Abstract]

Reporting Segments

Reporting Segments

During the first quarter of 2022, the Corporation changed the name of its C&IS segment to “Asset Servicing.” Accordingly, the disclosures herein and all future disclosures regarding the Corporation’s reporting segments filed with, or furnished to, the SEC will refer to this segment as Asset Servicing. This change has not had, and is not expected in the future to have, any impact upon the methodology by which the Corporation allocates revenue and expense to each of its reporting segments.

Northern Trust is organized around its two client-focused reporting segments: Asset Servicing and Wealth Management. Asset management and related services are provided to Asset Servicing and Wealth Management clients primarily by the Asset Management business. The revenue and expenses of Asset Management and certain other support functions are allocated fully to Asset Servicing and Wealth Management.

Reporting segment financial information, presented on an internal management reporting basis, is determined by accounting systems used to allocate revenue and expense to each segment, and incorporates processes for allocating assets, liabilities, equity and the applicable interest income and expense utilizing a funds transfer pricing (FTP) methodology. Under the methodology, assets and liabilities receive a funding charge or credit that considers interest rate risk, liquidity risk, and other product characteristics on an instrument level. Additionally, segment information is presented on an FTE basis as management

believes an FTE presentation provides a clearer indication of net interest income. The adjustment to an FTE basis has no impact on Net Income.

Revenues, expenses and average assets are allocated to Asset Servicing and Wealth Management, with the exception of non-recurring activities such as certain costs associated with acquisitions, divestitures, litigation, restructuring, and tax adjustments not directly attributable to a specific reporting segment.

Reporting segment results are subject to reclassification when organizational changes are made. The results are also subject to refinements in revenue and expense allocation methodologies, which are typically reflected on a prospective basis.

The following table presents the earnings contributions and average assets of Northern Trust’s reporting segments for the three month periods ended March 31, 2022 and 2021.

Revenue from Contracts with Clients

3 Months Ended

Mar. 31, 2022

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Clients

Revenue from Contracts with Clients

Trust, Investment, and Other Servicing Fees. Custody and Fund Administration income is comprised of revenues received from our core asset servicing business for providing custody, fund administration, and middle-office-related services, primarily to Asset Servicing clients. Investment Management and Advisory income contains revenue received from providing asset management and related services to Wealth Management and Asset Servicing clients and to Northern Trust sponsored funds. Securities Lending income represents revenues generated from securities lending arrangements that Northern Trust enters into as agent, mainly with Asset Servicing clients. Other income largely consists of revenues received from providing employee benefit, investment risk and analytic and other services to Asset Servicing and Wealth Management clients.

Other Noninterest Income. Treasury management income represents revenues received from providing cash and liquidity management services to Asset Servicing and Wealth Management clients. The portion of Security Commissions and Trading Income that relates to revenue from contracts with clients is primarily comprised of commissions earned from providing securities brokerage services to Wealth Management and Asset Servicing clients. The portion of Other Operating Income that relates to revenue from contracts with clients is mainly comprised of service fees for banking-related services provided to Wealth Management and Asset Servicing clients.

Performance Obligations. Clients are typically charged monthly or quarterly in arrears based on the fee arrangement agreed to with each client; payment terms will vary depending on the client and services offered.

Substantially all revenues generated from contracts with clients for asset servicing, asset management, securities lending, treasury management and banking-related services are recognized on an accrual basis, over the period in which services are provided. The nature of Northern Trust’s performance obligations is to provide a series of distinct services in which the customer simultaneously receives and consumes the benefits of the promised services as they are performed. Fee arrangements are mainly comprised of variable amounts based on market value of client assets managed and serviced, transaction volumes, number of accounts, and securities lending volume and spreads. Revenue is recognized using the output method in an amount that reflects the consideration to which Northern Trust expects to be entitled in exchange for providing each month or quarter of service. For contracts with multiple performance obligations, revenue is allocated to each performance obligation based on the price agreed to with the client, representing its relative standalone selling price.

Security brokerage revenue is primarily represented by securities commissions received in exchange of providing trade execution related services. Control is transferred at a point in time, on the trade date of the transaction, and fees are typically variable based on transaction volumes and security types.

Northern Trust’s contracts with its clients are typically open-ended arrangements and are therefore considered to have an original duration of less than one year. Northern Trust has elected the practical expedient to not disclose the value of remaining performance obligations for contracts with an original expected duration of one year or less.

The following table presents revenues disaggregated by major revenue source.

Other Operating Income decreased compared to the prior-year quarter, primarily driven by the accounting reclassification and lower miscellaneous income. The lower miscellaneous income was primarily associated with a market value decrease in the supplemental compensation plans, which also resulted in a related decrease in supplemental compensation plan expense reported in Other Operating Expense.

Share-Based Compensation Plans

The Northern Trust Corporation 2017 Long-Term Incentive Plan provides for the grant of non-qualified and incentive stock options; tandem and free-standing stock appreciation rights; stock awards in the form of restricted stock, restricted stock units and other stock awards; and performance awards.

Beginning with the grants made on February 21, 2017 under the Corporation’s prior equity incentive plan, restricted stock unit and performance stock unit grants continue to vest in accordance with the original terms of the award if the applicable employee retires after satisfying applicable age and service requirements.

Compensation expense for the three months ended March 31, 2022 included $32.6 million attributable to restricted stock units granted to retirement-eligible employees that were expensed in their entirety on the date of grant, compared to $21.8 million in the prior-year quarter.

There were no non-qualified stock option grants in the three months ended March 31, 2022 and 2021.

The Corporation granted 211,906 performance stock units with a total grant-date fair value of $24.1 million during the three months ended March 31, 2022, compared to 200,066 performance stock units with a total grant-date fair value of $19.5 million during the three months ended March 31, 2021.

Variable Interest Entities

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Variable Interest Entities

Variable Interest Entities

Variable Interest Entities (VIEs) are defined within GAAP as entities which either (1) lack sufficient equity at risk to permit the entity to finance its activities without additional subordinated financial support, (2) have equity investors that lack attributes typical of an equity investor, such as the ability to make significant decisions through voting rights affecting the entity’s operations, or the obligation to absorb expected losses or the right to receive residual returns of the entity, or (3) are structured with voting rights that are disproportionate to the equity investor’s obligation to absorb losses or right to receive returns, and substantially all of the activities are conducted on behalf of the holder of the equity investment at risk with disproportionately few voting rights. Investors that finance a VIE through debt or equity interests are variable interest holders in the entity and the variable interest holder, if any, that has both the power to direct the activities that most significantly impact the entity’s economic performance and, through its variable interest, the obligation to absorb losses or the right to receive returns that could potentially be significant to the entity is deemed to be the VIE’s primary beneficiary and is required to consolidate the VIE.

Tax Credit Structures. Northern Trust invests in qualified affordable housing projects and community development entities (collectively, community development projects) that are designed to generate a return primarily through the realization of tax credits. The community development projects are formed as limited partnerships and limited liability companies in which Northern Trust invests as a limited partner/investor member through equity contributions. The economic performance of the community development projects, some of which are VIEs, is subject to the performance of their underlying investment and their ability to operate in compliance with the rules and regulations necessary for the qualification of tax credits generated by equity investments. Northern Trust has determined that it is not the primary beneficiary of any community development project VIEs as it lacks the power to direct the activities that most significantly impact the economic performance of the underlying investments or to affect their ability to operate in compliance with the rules and regulations necessary for the qualification of

tax credits generated by equity investments. This power is held by the general partners and managing members who exercise full and exclusive control of the operations of the community development project VIEs.

Northern Trust’s maximum exposure to loss as a result of its involvement with community development projects is limited to the carrying amounts of its investments, including any undrawn commitments. As of March 31, 2022 and December 31, 2021, the carrying amounts of these investments in community development projects that generate tax credits, included in Other Assets on the consolidated balance sheets, totaled $916.5 million and $916.8 million, respectively, of which $876.4 million and $880.0 million are VIEs as of March 31, 2022 and December 31, 2021, respectively. As of March 31, 2022 and December 31, 2021, liabilities related to unfunded commitments on investments in tax credit community development projects, included in Other Liabilities on the consolidated balance sheets, totaled $297.4 million and $289.3 million, respectively, of which $281.8 million and $280.5 million related to undrawn commitments on VIEs as of March 31, 2022 and December 31, 2021, respectively. Northern Trust’s funding requirements are limited to its invested capital and undrawn commitments for future equity contributions. Northern Trust has no exposure to loss from liquidity arrangements and no obligation to purchase assets of the community development projects.

Tax credits and other tax benefits attributable to community development projects totaled $22.7 million and $23.0 million for the three months ended March 31, 2022 and 2021, respectively.

Investment Funds. Northern Trust acts as asset manager for various funds in which clients of Northern Trust are investors. As an asset manager of funds, Northern Trust earns a competitively priced fee that is based on assets managed and varies with each fund’s investment objective. Based on its analysis, Northern Trust has determined that it is not the primary beneficiary of these VIEs under GAAP.

Some of the funds for which Northern Trust acts as asset manager comply or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds and therefore the funds are exempt from the consolidation requirements in ASC 810-10. Northern Trust voluntarily waived $50.7 million and $50.2 million of money market mutual fund fees for the three months ended March 31, 2022 and 2021, respectively, related to the low-interest-rate environment and certain competitive factors. Northern Trust does not have any contractual obligations to provide financial support to the funds. Any potential future support of the funds will be at the discretion of Northern Trust after an evaluation of the specific facts and circumstances.

Periodically, Northern Trust makes seed capital investments to certain funds. As of March 31, 2022, and December 31, 2021, Northern Trust had no seed capital investments and no unfunded commitments related to seed capital investments.

Commitments and Contingent Liabilities

Commitments and Contingent Liabilities

Off-Balance Sheet Financial Instruments, Guarantees and Other Commitments. Northern Trust, in the normal course of business, enters into various types of commitments and issues letters of credit to meet the liquidity and credit enhancement needs of its clients. The contractual amounts of these instruments represent the maximum potential credit exposure should the instrument be fully drawn upon and the client default. To control the credit risk associated with entering into commitments and issuing letters of credit, Northern Trust subjects such activities to the same credit quality and monitoring controls as its lending activities. Northern Trust does not believe the total contractual amount of these instruments to be representative of its future credit exposure or funding requirements.

The following table provides details of Northern Trust's off-balance sheet financial instruments as of March 31, 2022 and December 31, 2021.

TABLE 68: SUMMARY OF OFF-BALANCE SHEET FINANCIAL INSTRUMENTS

	MARCH 31, 2022						DECEMBER 31, 2021
($ In Millions)	ONE YEAR AND LESS		OVER ONE YEAR		TOTAL		ONE YEAR AND LESS		OVER ONE YEAR		TOTAL

Total Off-Balance Sheet Financial Instruments	$	170,070.7	$	18,923.7	$	188,994.4	$	183,566.4	$	18,410.2	$	201,976.6

(1) These amounts exclude $402.0 million and $366.6 million of commitments participated to others at March 31, 2022 and December 31, 2021, respectively.

(2) These amounts include $35.7 million and $30.5 million of standby letters of credit secured by cash deposits or participated to others as of March 31, 2022 and December 31, 2021, respectively.

(3) These amounts include a $2,674.8 million and $2,309.6 million guarantee to the Fixed Income Clearing Corporation (FICC) under the sponsored member program, without taking into consideration the related collateral, as of March 31, 2022 and December 31, 2021, respectively.

Undrawn Commitments generally have fixed expiration dates or other termination clauses. Since a significant portion of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future loans or liquidity requirements.

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. 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 collateral received or other participants.

Financial Guarantees are issued by Northern Trust to guarantee the performance of a client to a third party under certain arrangements.

Commercial Letters of Credit are instruments issued by Northern Trust on behalf of its clients that authorize a third party (the beneficiary) to draw drafts up to a stipulated amount under the specified terms and conditions of the agreement and other similar instruments. Commercial letters of credit are issued primarily to facilitate international trade.

Custody Securities Lent with Indemnification involves Northern Trust lending securities owned by clients to borrowers who are reviewed and approved by the Northern Trust Capital Markets Credit Committee, as part of its securities custody activities and at the direction of its clients. In connection with these activities, Northern Trust has issued indemnifications to certain clients against certain losses that are a direct result of a borrower’s failure to return securities when due, should the value of such securities exceed the value of the collateral required to be posted. Borrowers are required to collateralize fully securities received with cash or marketable securities. As securities are loaned, collateral is maintained at a minimum of 100% of the fair value of the securities plus accrued interest. The collateral is revalued on a daily basis. The amount of securities loaned as of March 31, 2022 and December 31, 2021 subject to indemnification was $155.7 billion and $170.4 billion, respectively. Because of the credit quality of the borrowers and the requirement to fully collateralize securities borrowed, management believes that the exposure to credit loss from this activity is not significant and no liability was recorded as of March 31, 2022 or December 31, 2021, related to these indemnifications.

Unsettled Repurchase and Reverse Repurchase Agreements. Northern Trust enters into repurchase agreements and reverse repurchase agreements which may settle at a future date. In repurchase agreements, Northern Trust receives cash from and provides securities as collateral to a counterparty. In reverse repurchase agreements, Northern Trust advances cash to and receives securities as collateral from a counterparty. These transactions are recorded on the consolidated balance sheets on the settlement date. As of March 31, 2022 and December 31, 2021, there were no unsettled repurchase or reverse repurchase agreements.

Sponsored Member Program. Northern Trust is an approved Government Securities Division (GSD) netting and sponsoring member in the FICC sponsored member program, through which Northern Trust submits eligible repurchase and reverse repurchase transactions in U.S. Government securities between Northern Trust and its sponsored member clients for novation and clearing. Northern Trust may sponsor clients to clear their eligible repurchase transactions with the FICC. As a sponsoring member, Northern Trust guarantees to the FICC the prompt and full payment and performance of its sponsored member clients’ respective obligations under the FICC GSD’s rules. To mitigate Northern Trust’s credit exposure under this guarantee, Northern Trust obtains a security interest in its sponsored member clients’ collateral. See Note 23 — Offsetting of Assets and Liabilities for additional information on Northern Trust’s repurchase and reverse repurchase agreements.

Clearing and Settlement Organizations. The Bank is a participating member of various cash, securities and foreign exchange clearing and settlement organizations. It participates in these organizations on behalf of its clients and on its own behalf as a result of its own activities. A wide variety of cash and securities transactions are settled through these organizations, including those involving U.S. Treasuries, obligations of states and political subdivisions, asset-backed securities, commercial paper, dollar placements, and securities issued by the Government National Mortgage Association.

Certain of these industry clearing and settlement exchanges require their members to guarantee their obligations and liabilities and/or to provide liquidity support in the event other members do not honor their obligations as stipulated in each clearing organization’s membership agreement. Exposure related to these agreements varies, primarily as a result of fluctuations in the volume of transactions cleared through the organizations. At March 31, 2022 and December 31, 2021, Northern Trust has not recorded any material liabilities under these arrangements as Northern Trust believes the likelihood that a clearing or settlement exchange (of which Northern Trust is a member) would become insolvent is remote. Controls related to these clearing transactions are closely monitored by management to protect the assets of Northern Trust and its clients.

Legal Proceedings. In the normal course of business, the Corporation and its subsidiaries are routinely defendants in or parties to pending and threatened legal actions, and are subject to regulatory examinations, information-gathering requests, investigations, and proceedings, both formal and informal. In certain legal actions, claims for substantial monetary damages are

asserted. In regulatory matters, claims for disgorgement, restitution, penalties and/or other remedial actions or sanctions may be sought.

Based on current knowledge, after consultation with legal counsel and after taking into account current accruals, management does not believe that losses, fines or penalties, if any, arising from pending litigation or threatened legal actions or regulatory matters either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage will have a material adverse effect on the consolidated financial position or liquidity of the Corporation, although such matters could have a material adverse effect on the Corporation’s operating results for a particular period.

Under GAAP, (i) an event is “probable” if the “future event or events are likely to occur”; (ii) an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely”; and (iii) an event is “remote” if “the chance of the future event or events occurring is slight.”

The outcome of litigation and regulatory matters is inherently difficult to predict and/or the range of loss often cannot be reasonably estimated, particularly for matters that (i) will be decided by a jury, (ii) are in early stages, (iii) involve uncertainty as to the likelihood of a class being certified or the ultimate size of the class, (iv) are subject to appeals or motions, (v) involve significant factual issues to be resolved, including with respect to the amount of damages, (vi) do not specify the amount of damages sought or (vii) seek very large damages based on novel and complex damage and liability legal theories. Accordingly, the Corporation cannot reasonably estimate the eventual outcome of these pending matters, the timing of their ultimate resolution or what the eventual loss, fines or penalties, if any, related to each pending matter will be.

In accordance with applicable accounting guidance, the Corporation records accruals for litigation and regulatory matters when those matters present loss contingencies that are both probable and reasonably estimable. When loss contingencies are not both probable and reasonably estimable, the Corporation does not record accruals. No material accruals have been recorded for pending litigation or threatened legal actions or regulatory matters.

For a limited number of matters for which a loss is reasonably possible in future periods, whether in excess of an accrued liability or where there is no accrued liability, the Corporation is able to estimate a range of possible loss. As of March 31, 2022, the Corporation has estimated the range of reasonably possible loss for these matters to be from zero to approximately $25 million in the aggregate. The Corporation’s estimate with respect to the aggregate range of reasonably possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate.

In certain other pending matters, there may be a range of reasonably possible loss (including reasonably possible loss in excess of amounts accrued) that cannot be reasonably estimated for the reasons described above. Such matters are not included in the estimated range of reasonably possible loss discussed above.

In 2015, Northern Trust Fiduciary Services (Guernsey) Limited (NTFS), an indirect subsidiary of the Corporation, was charged by a French investigating magistrate judge with complicity in estate tax fraud in connection with the administration of two trusts for which it serves as trustee. Charges also were brought against a number of other persons and entities related to this matter. In 2017, a French court found no estate tax fraud had occurred and NTFS and all other persons and entities charged were acquitted. The Public Prosecutor’s Office of France appealed the court decision and in June 2018 a French appellate court issued its opinion on the matter, acquitting all persons and entities charged, including NTFS. In January 2021, the Cour de Cassation, the highest court in France, reversed the June 2018 appellate court ruling, requiring a re-trial at the appellate court level. The re-trial proceedings in the appellate court have not yet been scheduled. As trustee, NTFS provided no tax advice and had no involvement in the preparation or filing of the challenged estate tax filings.

Visa Class B Common Shares. Northern Trust, as a member of Visa U.S.A. Inc. (Visa U.S.A.) and in connection with the 2007 restructuring of Visa U.S.A. and its affiliates and the 2008 initial public offering of Visa Inc. (Visa), received certain Visa Class B common shares. The Visa Class B common shares are subject to certain selling restrictions until the final resolution of certain litigation related to interchange fees involving Visa (the covered litigation), at which time the shares are convertible into Visa Class A common shares based on a conversion rate dependent upon the ultimate cost of resolving the covered litigation. On June 28, 2018, September 27, 2019 and December 29, 2021, Visa deposited an additional $600 million, $300 million, and $250 million, respectively, into an escrow account previously established with respect to the covered litigation. As a result of the additional contributions to the escrow account, the rate at which Visa Class B common shares will convert into Visa Class A common shares was reduced.

In September 2018, Visa reached a proposed class settlement agreement covering damage claims but not injunctive relief claims regarding the covered litigation. In December 2019, the district court granted final approval for the proposed class settlement agreement. Certain merchants have opted out of the class settlement and are pursuing claims separately, while other merchants have appealed the approval order granted by the district court. The ultimate resolution of the covered litigation, the

timing for removal of the selling restrictions on the Visa Class B common shares and the rate at which such shares will ultimately convert into Visa Class A common shares are uncertain.

In June 2016 and 2015, Northern Trust recorded a $123.1 million and $99.9 million net gain on the sale of 1.1 million and 1.0 million of its Visa Class B common shares, respectively. These sales do not affect Northern Trust’s risk related to the impact of the covered litigation on the rate at which such shares will ultimately convert into Visa Class A common shares. Northern Trust continued to hold approximately 4.1 million Visa Class B common shares, which are recorded at their original cost basis of zero, as of March 31, 2022 and December 31, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

Northern Trust is a party to various derivative financial instruments that are used in the normal course of business to meet the needs of its clients, as part of its trading activity for its own account and as part of its risk management activities. These instruments may include foreign exchange contracts, interest rate contracts, total return swap contracts, and swaps related to the sale of certain Visa Class B common shares.

Foreign exchange contracts are agreements to exchange specific amounts of currencies at a future date, at a specified rate of exchange. Foreign exchange contracts are entered into primarily to meet the foreign exchange needs of clients. Foreign exchange contracts are also used for trading and risk management purposes. For risk management purposes, Northern Trust uses foreign exchange contracts to reduce its exposure to changes in foreign exchange rates relating to certain forecasted non-functional-currency-denominated revenue and expenditure transactions, foreign-currency-denominated assets and liabilities, including debt securities, and net investments in non-U.S. affiliates.

Interest rate contracts include swap and option contracts. Interest rate swap contracts involve the exchange of fixed and floating rate interest payment obligations without the exchange of the underlying principal amounts. Northern Trust enters into interest rate swap contracts with its clients and also may utilize such contracts to reduce or eliminate the exposure to changes in the cash flows or fair value of hedged assets or liabilities due to changes in interest rates. Interest rate option contracts may include caps, floors, collars and swaptions, and provide for the transfer or reduction of interest rate risk, typically in exchange for a fee. Northern Trust enters into option contracts primarily as a seller of interest rate protection to clients. Northern Trust receives a fee at the outset of the agreement for the assumption of the risk of an unfavorable change in interest rates. This assumed interest rate risk is then mitigated by entering into an offsetting position with an outside counterparty. Northern Trust may also purchase or enter into option contracts for risk management purposes including to reduce the exposure to changes in the cash flows of hedged assets due to changes in interest rates.

The following table shows the notional and fair values of all derivative financial instruments as of March 31, 2022 and December 31, 2021.

Notional amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance sheets. They are used merely to express the volume of this activity. Northern Trust’s credit-related risk of loss is limited to the positive fair value of the derivative instrument, net of any collateral received, which is significantly less than the notional amount.

All derivative financial instruments, whether designated as hedges or not, are recorded on the consolidated balance sheets at fair value within Other Assets or Other Liabilities. Northern Trust has elected to net derivative assets and liabilities when legally enforceable master netting arrangements or similar agreements exist between Northern Trust and the counterparty.

Hedging Derivative Instruments Designated under GAAP. Northern Trust uses derivative instruments to hedge its exposure to foreign currency, interest rate, and equity price. Certain hedging relationships are formally designated and qualify for hedge accounting under GAAP as fair value, cash flow or net investment hedges. Other derivatives that are entered into for risk management purposes as economic hedges are not formally designated as hedges and changes in fair value are recognized currently in Other Operating Income within the consolidated statements of income (see below section “Derivative Instruments Not Designated as Hedging under GAAP”).

In order to qualify for hedge accounting, a formal assessment is performed on a calendar-quarter basis to verify that derivatives used in designated hedging transactions continue to be highly effective in offsetting the changes in fair value or cash flows of the hedged item. If a derivative ceases to be highly effective, matures, is sold or is terminated, or if a hedged forecasted transaction is no longer probable of occurring, hedge accounting is terminated and the derivative is treated as if it were a trading instrument.

Fair Value Hedges. Derivatives are designated as fair value hedges to limit Northern Trust’s exposure to changes in the fair value of assets and liabilities due to movements in interest rates. Northern Trust enters into interest rate swaps to hedge changes in fair value of AFS debt securities and long-term subordinated debt and senior notes. Northern Trust applied the “shortcut” method of accounting, available under GAAP, which assumes there is perfect effectiveness in a hedge, for all of its fair value hedges during the three month periods ended March 31, 2022 and 2021. Changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability attributable to the hedged risk are recognized currently in earnings within the same income statement line item.

Cash Flow Hedges. Derivatives are also designated as cash flow hedges in order to minimize the variability in cash flows of earning assets or forecasted transactions caused by movements in interest or foreign exchange rates. Northern Trust enters into foreign exchange contracts to hedge changes in cash flows due to movements in foreign exchange rates of forecasted foreign- currency-denominated transactions and foreign-currency-denominated debt securities. Northern Trust also enters into interest rate contracts to hedge changes in cash flows due to movements in interest rates of AFS debt securities. The change in fair value of cash flow hedging derivative instruments are recorded in AOCI and reclassified to earnings when the hedged forecasted transaction impacts earnings within the same income statement line item.

There were no material gains or losses reclassified into earnings during the three month periods ended March 31, 2022 and 2021, as a result of the discontinuance of forecasted transactions that were no longer probable of occurring. It is estimated that net losses of $4.9 million will be reclassified into net income within the next twelve months relating to cash flow hedges of foreign-currency-denominated transactions. As of March 31, 2022, 17 months was the maximum length of time over which the exposure to variability in future cash flows of forecasted foreign-currency-denominated transactions was being hedged.

The following tables provide fair value and cash flow hedge derivative gains and losses recognized in income during the three-month periods ended March 31, 2022 and 2021.

(3)    Carrying value represents amortized cost.

Net Investment Hedges. Certain foreign exchange contracts are designated as net investment hedges to minimize Northern Trust’s exposure to variability in the foreign currency translation of net investments in non-U.S. branches and subsidiaries. Net investment hedge gains of $59.4 million and $82.7 million were recognized in AOCI related to foreign exchange contracts for the three months ended March 31, 2022 and 2021, respectively.

Derivative Instruments Not Designated as Hedging under GAAP. Northern Trust’s derivative instruments that are not designated as hedging under GAAP include derivatives for purposes of client-related and trading activities, as well as other risk management purposes. These activities consist principally of providing foreign exchange services to clients in connection with

Northern Trust’s global custody business. However, in the normal course of business, Northern Trust also engages in trading of currencies for its own account.

Non-designated risk management derivatives include foreign exchange contracts entered into to manage the foreign currency risk of non-U.S.-dollar-denominated assets and liabilities, the net investment in certain non-U.S. affiliates, commercial loans and forecasted foreign-currency-denominated transactions. Swaps related to sales of certain Visa Class B common shares were entered into pursuant to which Northern Trust retains the risks associated with the ultimate conversion of the Visa Class B common shares into Visa Class A common shares. Total return swaps are entered into to manage the equity price risk associated with certain investments.

Changes in the fair value of derivative instruments not designated as hedges under GAAP are recognized currently in income. The following table provides the location and amount of gains and losses recorded in the consolidated statements of income for the three months ended March 31, 2022 and 2021 for derivative instruments not designated as hedges under GAAP.

(1)Derivative liabilities are reported in Other Liabilities on the consolidated balance sheets. Other Liabilities (excluding derivative liabilities) totaled $3.3 billion at both March 31, 2022 and December 31, 2021.

(2)Offsetting of Securities Sold under Agreements to Repurchase primarily relates to our involvement in FICC.

(3)Including cash collateral deposited with counterparties.

(4)Including financial assets accepted as collateral which are deposited with counterparties.

(5)Northern Trust did not place any cash collateral with counterparties that was not offset in the consolidated balance sheets that could have been used to offset the net amounts presented in the consolidated balance sheets as of March 31, 2022 and December 31, 2021.

All of Northern Trust’s securities sold under agreements to repurchase (repurchase agreements) and securities purchased under agreements to resell (reverse repurchase agreements) involve the transfer of financial assets in exchange for cash subject to a right and obligation to repurchase those assets for an agreed upon amount. In the event of a repurchase failure, the cash or financial assets are available for offset. All of Northern Trust’s repurchase agreements and reverse repurchase agreements are subject to a master netting arrangement, which sets forth the rights and obligations for repurchase and offset. Under the master netting arrangement, Northern Trust is entitled to offset receivables from and collateral placed with a single counterparty against obligations owed to that counterparty. In addition, collateral held by Northern Trust can be offset against receivables from that counterparty. Northern Trust’s repurchase agreements and reverse repurchase agreements, other than those in which the counterparty is FICC, do not meet the requirements to net under GAAP.

Derivative asset and liability positions with a single counterparty can be offset against each other in cases where legally enforceable master netting arrangements or similar agreements exist. Derivative assets and liabilities can be further offset by cash collateral received from, and deposited with, the transacting counterparty. The basis for this view is that, upon termination of transactions subject to a master netting arrangement or similar agreement, the individual derivative receivables do not represent resources to which general creditors have rights and individual derivative payables do not represent claims that are equivalent to the claims of general creditors.

Credit risk associated with derivative instruments relates to the failure of the counterparty and the failure of Northern Trust to pay based on the contractual terms of the agreement, and is generally limited to the unrealized fair value gains and losses on these instruments, net of any collateral received or deposited. The amount of credit risk will increase or decrease during the

lives of the instruments as interest rates, foreign exchange rates, or equity prices fluctuate. Northern Trust’s risk is controlled by limiting such activity to an approved list of counterparties and by subjecting such activity to the same credit and quality controls as are followed in lending and investment activities. Credit Support Annexes and other similar agreements are currently in place with a number of Northern Trust’s counterparties which mitigate the aforementioned credit risk associated with derivative activity conducted with those counterparties by requiring that significant net unrealized fair value gains be supported by collateral placed with Northern Trust.

Additional cash collateral received from and deposited with derivative counterparties totaling $257.5 million and $150.5 million, respectively, as of March 31, 2022, and $93.5 million and $43.4 million, respectively, as of December 31, 2021, was not offset against derivative assets and liabilities in the consolidated balance sheets as the amounts exceeded the net derivative positions with those counterparties.

Certain master netting arrangements Northern Trust enters into with derivative counterparties contain credit-risk-related contingent features in which the counterparty has the option to declare Northern Trust in default and accelerate cash settlement of net derivative liabilities with the counterparty in the event Northern Trust’s credit rating falls below specified levels. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position was $1,163.8 million and $111.5 million at March 31, 2022 and December 31, 2021, respectively. Cash collateral amounts deposited with derivative counterparties on those dates included $1,068.3 million and $84.2 million, respectively, posted against these liabilities, resulting in a net maximum amount of termination payments that could have been required at March 31, 2022 and December 31, 2021, of $95.5 million and $27.3 million, respectively. Accelerated settlement of these liabilities would not have a material effect on the consolidated financial position or liquidity of Northern Trust.

Accounting Changes and Error Corrections [Abstract]

Basis of Presentation

The consolidated financial statements include the accounts of Northern Trust Corporation (Corporation) and its wholly-owned subsidiary, The Northern Trust Company (Bank), and various other wholly-owned subsidiaries of the Corporation and Bank. Throughout the notes to the consolidated financial statements, the term “Northern Trust” refers to the Corporation and its subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements, as of and for the periods ended March 31, 2022 and 2021, 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. The accounting and financial reporting policies of Northern Trust conform to U.S. generally accepted accounting principles (GAAP) and reporting practices prescribed for the banking industry. The consolidated statements of income include results of acquired subsidiaries from the dates of acquisition. Certain prior-period balances have been reclassified to conform with the current year’s presentation.

Recent Accounting Pronouncements

On January 1, 2022, Northern Trust adopted Accounting Standards Update (ASU) No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contract in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06). ASU 2020-06 simplifies the convertible instrument accounting framework through the elimination of the beneficial conversion and cash conversion accounting models used to account for convertible debt and convertible preferred stock. ASU 2020-06 also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions in Accounting Standards Codification 815—Derivatives and Hedging. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. Upon adoption of ASU 2020-06, there was no significant impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.

On January 1, 2022, Northern Trust adopted ASU No. 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” (ASU 2021-10). ASU 2021-10 requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy to other accounting guidance within Topic 958, Not-for-Profit Entities, or International Accounting Standards 20, Accounting for Government Grants and Disclosure of Government Assistance. Upon adoption of ASU 2021-10, there was no significant impact to Northern Trust’s consolidated balance sheets or consolidated statements of income.
