U.S. Small Business Administration’s Paycheck Protection Program
During the second quarter of 2020, Northern Trust became a lender under the Paycheck Protection Program, as amended (PPP), which is administered by the U.S. Small Business Administration (SBA), an agency of the U.S. Department of the Treasury, which works with financial institutions in providing loans to small businesses. The PPP, which is meant to aid small businesses during the COVID-19 pandemic, was created under the Coronavirus Aid, Relief, and Economic Security (CARES) Act, which was signed into law on March 27, 2020.
As of March 31, 2021, Northern Trust had outstanding loans totaling $213.9 million under the PPP and 219 PPP loan forgiveness applications, totaling $34.2 million, went through the forgiveness process and were fully forgiven by the SBA as of such date.
The Economic Aid to Hard-Hit Small Businesses, Nonprofits and Venues Act (the Economic Aid Act) amended the PPP by extending the authority of the SBA to guarantee loans and the timingability of recent declines in short-term interest rates. Accordingly, revenue in future periods is expectedPPP lenders to be impacteddisburse PPP loans until March 31, 2021. The PPP Extension Act of 2021, which was enacted on March 30, 2021, extends the PPP application deadline to May 31, 2021 and provides the SBA additional time to process applications through June 30, 2021. For further by recent market events.

Key income statement drivers for the first quarter are highlighted below.
Net income per diluted common share increased in the current quarter to $1.55 from $1.48 in the first quarter of 2019. Net income increased to $360.6 million in the current quarter as compared to $347.1 million in the prior-year quarter.

Net interest income decreased $13.9 million, or 3%, to $408.1 million in the current quarter as compared to $422.0 million in the prior-year quarter, primarily due to a lower net interest margin.

Trust, investmentInvestment and other servicing feesOther 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. Accordingly,Low-interest-rate environments have historically had a negative impact on fees earned on certain products.
Beginning in the impactssecond quarter of lower equity markets were not fully reflected2020, the Corporation began to waive a portion of certain fees associated with money market mutual funds due to the low-interest-rate environment. Northern Trust voluntarily waived $50.2 million of money market mutual fund fees for the three months ended March 31, 2021 related to the low-interest-rate environment. These fee waivers, which are impacted by the level of yields earned and account balances in certain funds, are expected to continue in the current low-interest-rate environment as the yields in these funds remain insufficient to pay the stated fees associated with such funds. This is expected to adversely impact Trust, Investment and Other Servicing Fees within the C&IS and Wealth Management reporting segments.

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

Corporate & Institutional Services
Custody and Fund Administration fees, the largest component of C&IS 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.
Custody and Fund Administration fees increased from the prior-year quarter, primarily due to new business, favorable currency translation and higher transaction volumes. Investment Management fees decreased from the prior-year quarter, primarily due to money market mutual fund fee waivers, partially offset by new business and favorable markets. Securities Lending fees decreased from the prior-year quarter, primarily due to lower spreads.
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, due to favorable markets, partially offset by higher money market mutual fund fee waivers. Global Family Office fee income decreased from the prior-year quarter, primarily due to higher money market mutual fund fee waivers, partially offset by favorable markets.

Net Interest Income

Net interest incomeInterest Income is defined as the total of interest incomeInterest Income and amortized fees on earning assets, less interest expenseInterest Expense on deposits and borrowed funds, adjusted for the impact of interest-related hedging activity. Earning assets — assets—including federal funds sold, securities purchasedFederal Funds Sold, Securities Purchased under agreementsAgreements to resell, interest-bearing due from banks and interest-bearing deposits with banks,Resell, Interest-Bearing Due From Banks, Federal Reserve and other central bank depositsOther Central Bank Deposits and other, securities,Other, Securities, and loansLoans and leases — Leases—are financed by a large base of interest-bearing funds that include client deposits, short-term borrowings, senior notesSenior Notes and long-term debt.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 incomeInterest 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 Income.
Net interest margin is the difference between what we earn on our assets and the interest rateswhat 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 incomeNet Interest Income by average interest-earning assets.
Net interest incomeInterest 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.Net Income. A reconciliation of net interest incomeNet Interest Income on a GAAP basis to net interest incomeNet Interest Income on an FTE basis is provided on page 28.25.

Notes:Net Interest Income (FTE Adjusted), a non-GAAP financial measure, includes adjustments to a fully taxable equivalent basis for loans and securities. Such adjustments are based on a blended federal and state tax rate of 24.9% and 24.9% for the three months ended March 31, 2020 and 2019, respectively. Total taxable equivalent interest adjustments amounted to $8.1 million and $7.8 million for the three months ended March 31, 2020 and 2019, 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 on page 28. Net interest margin is calculated by dividing annualized net interest income by average interest-earning assets.
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 $6.6 million and $8.1 million for the three months ended March 31, 2021 and 2020, 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 on page 25.

Provision for Credit Losses


The Corporation adopted Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments” (ASU 2016-13) on January 1, 2020, which significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of financial instruments. Upon adoption of ASU 2016-13, the Corporation recorded a $13.7 million increase in the allowance for credit losses with a corresponding cumulative effect adjustment to decrease retained earnings $10.1 million, net of income taxes. For more information on the adoption of ASU 2016-13, please refer to Note 2 — Recent Accounting Pronouncements to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).
There was a $61.0$30.0 million provision forrelease of credit lossesreserves in the current quarter, as compared to noa provision of $61.0 million in the prior-year quarter. The provisionrelease of credit reserves in the current quarter 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 improvement in projected economic conditions and portfolio credit quality relative to the prior quarter, with decreases primarily in the commercial and institutional, commercial real estate, and private client portfolios.
The provision in the prior-year quarter was primarily due to an increase in the reserve evaluated on a collective basis driven by the current and projected economic conditions at the time resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with the largest increase in the commercial and institutional and commercial real estate portfolios. To In addition, a $13.7 million increase in the extent that our future forecasts show deterioration greater than that currently expected, our future provisionsallowance for credit losses, could further increase. The provision in the prior-year quarterwith a corresponding cumulative effect adjustment to decrease retained earnings of $10.1 million, net of income taxes, was primarily driven by an increase in the specific reserve related to outstanding loans and standby lettersrecorded on January 1, 2020 upon adoption of credit in the commercial and institutional portfolio, offset by a net recovery in the period.Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments.”
Net charge-offsrecoveries in the current quarter were $0.7$0.9 million, resulting from charge-offs of $1.8$0.4 million and recoveries of $1.1$1.3 million. The prior-year quarter included $1.2$0.7 million of net recoveries,charge-offs, reflecting $1.0$1.8 million of charge-offs and $2.2$1.1 million of recoveries.

REPORTING SEGMENTS
Northern Trust is organized around its two client-focused reporting segments: C&IS and Wealth Management. Asset management and related services are provided to C&IS 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 C&IS and Wealth Management.
Reporting segment financial information, presented on an internal management-reportingmanagement 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.
Revenues, expenses and average assets are allocated to C&IS 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.

Effective January 1, 2021, Northern Trust implemented enhancements to its FTP methodology, including enhancements impacting the allocation of net interest income between C&IS and Wealth Management. These methodology enhancements affect the results of each of these reporting segments. Due to the lack of historical information, segment results for periods ended prior to January 1, 2021 have not been revised to reflect the methodology enhancements.

Custody and fund administration fees,For the largest component of C&IS fees, are driven primarily by values of client AUC/A, transaction volumes and 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 one-month and one-quarter in arrears.
Custody and fund administration fees increased from the prior-year quarter primarily due to favorable lagged markets and new business, partially offset by unfavorable currency translation. Investment management fees increased from the prior-year quarter, primarily due to favorable lagged markets and new business.

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).
Northern Trust participates in the repurchase agreement market as a relatively low cost alternative for short-term funding. 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.

Nonaccrual Loans and Leases and Other Real Estate Owned


During the first quarter of 2020, the Corporation implemented a change in the classification of certain loans and leases to enhance the consistency of its reporting across various regulatory regimes. As a result, the loan and lease balances as of December 31, 2019 below have been adjusted to conform to the presentation for periods ended after such date. The adjustments generally reflected reclassification of loans from the commercial real estate class to commercial and institutional, residential real estate, and private client classes. There was no impact on total loans and leases previously reported.
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 waswere 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, renegotiations and renewals.

Nonaccrual assets of $105.5$125.3 million as of March 31, 2020 increased 2021 decreased primarily related to an increase in the commercial and institutional portfolio due to the addition of three new nonaccrual loans, partially offset by a net decrease in the residential real estate portfolio due to payoffs.net payoffs and charge-offs and a payoff of one nonaccrual loan in the commercial and institutional portfolio, partially offset by one new nonaccrual loan in the residential real estate 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 levelbasis and the quantitative and qualitative factors used in the determination of the allowance evaluated on a collective levelbasis within the allowance for credit losses.
Northern Trust’s underwriting standardscredit 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.

Allowance for Credit Losses

During the first quarter of 2020, the Corporation implemented a change in the classification of certain loans and leases to specific segments to enhance the consistency of its reporting across various regulatory regimes. The allowance for credit losses as of and prior to December 31, 2019 remains unadjusted, as the impact of the reclassification on the allowance was immaterial.
The Corporation adopted Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments” (ASU 2016-13) on January 1, 2020, which significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of financial instruments. Upon adoption of ASU 2016-13, the Corporation recorded a $13.7 million increase in the allowance for credit losses with a corresponding cumulative effect adjustment to decrease retained earnings $10.1 million, net of income taxes. For more information on the adoption of ASU 2016-13, please refer to Note 2 — Recent Accounting Pronouncements to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).
The allowance for credit losses — 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 — 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.

CAPITAL RATIOS
The capital ratios of Northern Trust Corporation and its principal subsidiary, The Northern Trust Company, remained strong at March 31, 2020,2021, exceeding the minimum requirements for classification as “well-capitalized” under applicable U.S. regulatory requirements.
DuringAs a result of the first quarter ofstress test results published by the Federal Reserve on June 25, 2020, Northern Trust Corporation contributed $500 millionTrust’s stress capital buffer requirement for the 2020 Capital Plan cycle was set at 2.5%. The 2020 stress capital buffer became effective October 1, 2020, and results in an effective common equity tier 1 capital ratio minimum requirement of capital to its wholly-owned subsidiary, The Northern Trust Company. Other drivers contributing to the change in capital ratios from the prior period include the redemption7.0% inclusive of all outstanding shares of the Corporation’s Series C Non-Cumulative Perpetual Preferred Stock and the increase in total assets and risk-weighted assets. this buffer.

Further, on March 23, 2020, the Federal Reserve issued a temporary rule that required bank holding companies, including Northern Trust Corporation, to deduct their deposits with the Federal Reserve and investments in U.S. Treasury securities from their total leverage exposure. The U.S. Treasury securities deduction is applied in addition to the central bank deposits relief referred to above. This rule became effective on April 1, 2020 and expired on April 1, 2021.
On May 15, 2020, the U.S. federal banking agencies issued a temporary rule that permitted, but did not require, insured depository institutions of bank holding companies to exclude deposits with the Federal Reserve and investments in U.S. Treasury securities from their total leverage exposure. The Northern Trust Company did not elect to take this deduction.
CRITICAL ACCOUNTING ESTIMATES

For a description of Northern Trust’s significant accounting policies, refer to Note 1 — Summary of Significant Accounting Policies included under Item 8. Financial StatementsThe supplementary leverage ratios at March 31, 2021 and Supplementary Data in the Annual Report on Form 10-K for the year ended December 31, 2019. The use of estimates and assumptions is required in the preparation of financial statements in conformity with GAAP and actual results could differ from those estimates. The SEC has issued guidance relating to the disclosure of critical accounting estimates. Critical accounting estimates are those that require management to make subjective or complex judgments about the effect of matters that are inherently uncertain and may change in subsequent periods. Changes that may be required in the underlying assumptions or estimates in these areas could have a material impact on Northern Trust’s future financial condition and results of operations.

CRITICAL ACCOUNTING ESTIMATES (continued)




For Northern Trust, accounting estimates that are viewed as critical are those relating to the allowance2020 for credit losses and pension plan accounting. Management has discussed the development and selection of each critical accounting estimate with the Audit Committee of the Board of Directors (Audit Committee). For a description of Northern Trust’s estimate related to pension plan accounting, refer to the Critical Accounting Estimates section in the Annual Report on Form 10-K for the year ended December 31, 2019.

Allowance for Credit Losses
The Corporation adopted Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments” (ASU 2016-13) on January 1, 2020, which significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of financial instruments. Upon adoption of ASU 2016-13, the Corporation recorded a $13.7 million increase in the allowance for credit losses with a corresponding cumulative effect adjustment to decrease retained earnings $10.1 million, net of income taxes. For more information on the adoption of ASU 2016-13, please refer to Note 2 — Recent Accounting Pronouncements to the consolidated financial statements provided in Item 1. Consolidated Financial Statements (unaudited).

The allowance for credit losses — which represents management’s 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. Due to the inherent imprecision in accounting estimates, other estimates or assumptions could reasonably have been used in 2020 and changes in estimates are reasonably likely to occur from period to period.

The allowance for credit losses consists of the following components:

Evaluated on an Individual Level: The allowance is determined through an individual evaluation of financial assets considered impaired 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 impaired 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.

Evaluated on a Collective Level: 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 internal loss data specific to the Northern Trust financial asset portfolio from a historical observation period that includes both expansionaryCorporation and recessionary periods. The estimation methodology and the related qualitative adjustment framework segregate the loan and lease portfolio into segments based on loan and obligor-specific factors, including loan type, borrower type, collateral type, loan size, and borrower credit quality. For each segment, the probability of default and loss given default are derived for each remaining quarter of the loan’s contractual life from models developed using historical data on macroeconomic factors and loans with similar factors. For quarters outside of the approved projection period, historical average loss rates for loans by segment are used. The exposure at default for every quarter is based on contractual balances as of each quarter-end, with adjustments made for potential draw-downs of revolving lines.

Northern Trust utilizes a quantitative probabilityCompany reflect the impact 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 defaultand 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.these final rules.

CRITICAL ACCOUNTING ESTIMATES (continued)


Allowance for Credit Losses (continued)

ASU 2016-13 requires the use of projected macroeconomic factors. Northern Trust’s current projection period is eight quarters, with a four-quarter straight-line reversion period to historical average loss rates. The Corporation uses multiple forecasts which are approved by Northern Trust’s Macroeconomic Scenario Design Committee (MSDC). The baseline forecast aligns with the Corporation’s latest thinking on macroeconomic projections for the next eight quarters. The forecasts are weighted at each evaluation period and are management’s best estimate of future economic projections at that time.

The allowance estimate is sensitive to changes in portfolio composition and quality, and macroeconomic forecasts. Increases in the amount of borrowing and material downgrades to the quality of the lending portfolio will increase the reserve, all else equal. Similarly, deteriorating projections for macroeconomic conditions will increase the reserve. Macroeconomic factors that are particularly correlated to Northern Trust’s loan and lease portfolio are equity market values, market volatility, corporate profits, house and commercial real estate price indices, unemployment, and disposable income. The investment security and other financial assets exposure portfolios are less sensitive to macroeconomic factors in terms of overall reserve impact due to factors such as high credit quality, short duration, and low historical losses.
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 MSDC, and also reviews and approves qualitative adjustments to the collective allowance in line with Northern Trust’s qualitative adjustment framework. In determining the appropriate adjustment, management applies judgment by assessing internal risk factors, potential limitations in the quantitative methodology and environmental factors that are not contemplated in the quantitative methodology, including potential changes to the portfolio or economic events from the time of the last model execution to the end of the quarter.

The quarterly analysis of the individual and collective allowance components and the control process maintained by Credit Risk Management and the lending staff are the principal methods relied upon by management for the timely identification of, and adjustment for, changes in estimated credit loss levels. In addition to Northern Trust’s own experience, management also considers regulatory guidance. Control processes and analyses employed to determine an appropriate level of allowance for credit losses are reviewed on at least an annual basis and modified as considered appropriate.

The provision for credit losses, which is charged to income, is the amount necessary to adjust the allowance for credit losses to the level deemed to be appropriate through the above process. Actual losses may vary from current estimates and the amount of the provision for credit losses may be either greater than or less than actual net charge-offs. Management believes that the allowance for credit losses adequately addresses these uncertainties and has been established at an appropriate level.
RECENT ACCOUNTING PRONOUNCEMENTS AND DEVELOPMENTS

In January 2020, the Financial Accounting Standards Board (FASB)There are no accounting pronouncements and developments issued Accounting Standards Update (ASU) No. 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815” (ASU 2020-01). ASU 2020-01 addresses two accounting issues: (1) applicationbut not yet effective as of the measurement alternative under Topic 321 in correlation with the transition into and out of the equity method under Topic 323 and (2) the measurement of certain forward contracts and purchased options to acquire equity securities. ASU 2020-01 clarifiesMarch 31, 2021 that an entity applying the measurement alternative under Topic 321 that must transition to the equity method under Topic 323 because of an observable transaction will remeasure its investment immediately before transition, whereas an entity applying the equity method under Topic 323 that must transition to Topic 321 because of an observable transaction will remeasure its investment immediately after transition. ASU 2020-01 also clarifies that certain forward contracts or purchased call options to acquire equity securities generally will be measured using the fair value principles of Topic 321 before settlement or exercise. ASU 2020-01 is effective for interim and annual periods beginning after December 15, 2020, although early adoption is permitted. ASU 2020-01 is notare expected to have a significant impact on Northern Trust’s consolidated financial conditionbalance sheets or results of operations.

In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04). The global transition toward alternative reference rates and away from referencing the London Interbank Offered Rate (LIBOR) and other interbank offered rates (Reference Rate Reform) is expected to have a significant impact on the volume of contract modifications, hedge accounting, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of Reference Rate Reform. ASU 2020-04 provides temporary

optional expedients and exceptions for applying GAAP to contract modifications, hedging relationships, and other transactions affected by Reference Rate Reform if certain criteria are met. The main provisions of ASU 2020-04 provide the following optional expedients: (1) simplification of the accounting evaluations under current GAAP for contract modifications, including loan, debt, lease and other contracts with potential embedded derivatives, if qualifying criteria are met (2) preservation of hedging relationships without dedesignation upon certain changes to the critical terms of an existing hedging relationship due to Reference Rate Reform and other optional hedge accounting relief provisions and (3) a one-time election to sell or transfer, or both sell and transfer, debt securities classified as held to maturity that reference a rate affected by Reference Rate Reform and are classified as held to maturity before January 1, 2020.

ASU 2020-04 can be adopted beginning as of March 12, 2020 through December 31, 2022 and may be applied as of the beginning of the interim period that includes March 12, 2020 or any date thereafter. The optional expedients in ASU 2020-04 for contract modifications and hedging relationships are applied prospectively, while the one-time election to sell or transfer, or both sell and transfer debt securities classified as held to maturity may be made at any time after March 12, 2020. The optional expedients and exceptions provided by ASU 2020-04 do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. Northern Trust has not adopted ASU 2020-04 as of March 31, 2020.ASU 2020-04 is not expected to have a significant impact on Northern Trust’s consolidated financial condition or results of operations.
MARKET RISK MANAGEMENT
There are two types of market risk, interest rate risk associated with the assets and liabilities on the balance sheet, and trading risk. Interest rate risk associated with the assets and liabilities on the balance sheet 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.
22

MARKET RISK MANAGEMENT (continued)

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, 2019.2020.
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.

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.

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:

MARKET RISK MANAGEMENT (continued)

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.

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 estimates, based on a variety of high confidence levels, of the potential loss in value that might be incurred if an adverse shift in non-U.S. currency exchange 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, 2020,2021, Northern Trust experienced no days withdid not incur an actual GFX trading loss in excess of the daily value-at-riskGFX VaR estimate.
The table below 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, 20202021 and 2019,2020, 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. 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, 2019.2020.
Note 2 – Recent Accounting Pronouncements

On January 1, 2020,2021, Northern Trust adopted Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses2020-01, “Investments—Equity Securities (Topic 326)321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Measurement of Credit Losses on Financial Instruments”Clarifying the Interactions between Topic 321, Topic 323, and Topic 815” (ASU 2016-13)2020-01). ASU 2016-13 significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of financial instruments. The main provisions of ASU 2016-13 include2020-01 addresses two accounting issues: (1) replacing the “incurred loss” approach under current GAAP with an “expected loss” model for instruments measured at amortized cost, (2) requiring entities to record an allowance for available for sale debt securities rather than reduce the carrying amountapplication of the investments, as is required bymeasurement alternative under Topic 321 in correlation with the other-than-temporary-impairment modeltransition into and out of the equity method under legacy GAAP,Topic 323 and (3) a simplified accounting model for(2) the measurement of certain forward contracts and purchased credit-impaired debtoptions to acquire equity securities. ASU 2020-01 clarifies that an entity applying the measurement alternative under Topic 321 that must transition to the equity method under Topic 323 because of an observable transaction will remeasure its investment immediately before transition, whereas an entity applying the equity method under Topic 323 that must transition to Topic 321 because of an observable transaction will remeasure its investment immediately after transition. ASU 2020-01 also clarifies that certain forward contracts or purchased call options to acquire equity securities and loans.

generally will be measured using the fair value principles of Topic 321 before settlement or exercise. Upon adoption of ASU 2016-13, Northern Trust recorded a $13.7 million increase in the allowance for credit losses with a corresponding cumulative effect adjustment to decrease retained earnings $10.1 million, net of income taxes, on January 1, 2020. Northern Trust did not restate comparative periods for the effects of applying ASU 2016-13. There was no significant impact to Northern Trust’s consolidated results of operations. Please refer to Note 7 — Allowance for Credit Losses for further information.

On January 1, 2020, Northern Trust adopted ASU No. 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (ASU 2017-04). ASU 2017-04 amends the subsequent measurement of goodwill whereby Step 2 from the goodwill impairment test is eliminated. As a result, the goodwill impairment test is performed by comparing the fair value of a reporting unit to its carrying value and an impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit.

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, 20202021 or the twelve months ended December 31, 2019.2020.
32

Notes to Consolidated Financial Statements (unaudited) (continued)
Level 1Quoted, active market prices for identical assets or liabilities.
Northern Trust’s Level 1 assets are comprised of available for sale investments in U.S. treasuryTreasury 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 available for sale 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 pre-determined 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, 2020,2021, Northern Trust’s available for sale debt securities portfolio included 1,7712,471 Level 2 debt securities with an aggregate market value of $34.9$40.3 billion. All 1,7712,471 debt securities were valued by external pricing vendors. As of December 31, 2019,2020, Northern Trust’s available for sale debt securities portfolio included 1,7042,260 Level 2 debt securities with an aggregate market value of $34.3$39.2 billion. All 1,7042,260 debt securities were valued by external pricing vendors. Trading account debt securities, which totaled $1.2$0.4 million and $0.3$0.5 million as of March 31, 20202021 and December 31, 2019,2020, 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 2021 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, 20202021 and December 31, 2019,2020, 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.

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, 20202021 and December 31, 2019,2020, 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

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 $12.9$16.7 million and $8.0$24.6 million at March 31, 20202021 and December 31, 2019,2020, respectively.

As of March 31, 2020,2021, Northern Trust did not intend to sell any debt securities available for sale 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.

Debt securities available for sale 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 relatedcredit-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 0 provision for credit losses for corporate debt securities available for sale for the three months ended March 31, 2021, while there was a $0.2 million ofprovision for the three months ended March 31, 2020. There was 0 allowance for credit losses recognized for corporate debt securities available for sale as of March 31, 2020.2021 and December 31, 2020, respectively. The process for identifying credit losses for corporate debt available for sale 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.

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, 20202021 and December 31, 2019,2020, equity credit lines totaled $429.6$285.2 million and $448.5$304.4 million, respectively, and equity credit lines for which first liens were held by Northern Trust represented 96% and 97% of the total equity credit lines as of both March 31, 20202021 and December 31, 2019, respectively.2020.
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 $3.8$1.3 billion at March 31, 20202021 and $1.1 billion at December 31, 2019,2020, respectively. Demand deposit overdrafts reclassified as loan balances totaled $26.7$5.6 million and $90.4$26.4 million at March 31, 20202021 and December 31, 2019,2020, respectively.
As of March 31, 20202021 and December 31, 2019, there were $52.8 million and $53.6 million of leases, respectively, classified as held for sale related to the decision to sell substantially all of the lease portfolio. As of March 31, 2020, and December 31, 2019, there were 0 loans or 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 will have at least 90 days to respond as to the approval or denial of such application. 219 PPP loan forgiveness applications totaling $34.2 million that went through the forgiveness process as of March 31, 2021, were fully forgiven by the SBA as of such date.

Notes to Consolidated Financial Statements (unaudited) (continued)
As of March 31, 2021, Northern Trust had 1,137 outstanding loans totaling $213.9 million under the PPP in its commercial and institutional portfolio with an average loan balance of $0.2 million. For its origination efforts, Northern Trust received approximately $2.6 million in SBA fees, net of service charges as of March 31, 2021.
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, 20202021 and December 31, 20192020 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

Notes to Consolidated Financial Statements (unaudited) (continued)
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.

For credit quality indicator information that was required under the former provisions of Accounting Standards Code (ASC) Topic 310, please refer to Note 6 — Loans and Leases of the Notes to Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2019.

Interest income that would have been recorded for nonaccrual loans and leases in accordance with their original terms was $0.9 million and $1.3 million for the three months ended March 31, 2021 and March 31, 2020, 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, 2021 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 as TDRs starting in the calendar year of their restructuring. In subsequent years, a TDR may cease being

Notes to Consolidated Financial Statements (unaudited) (continued)
reported as a TDR 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 $73.4$78.8 million and $54.9$38.9 million of nonaccrual TDRs, and $22.6$23.3 million and $27.7$29.3 million of accrual TDRs as of March 31, 20202021 and December 31, 2019,2020, respectively.
There were $11.7$8.9 million and $8.2$10.4 million of aggregate undrawn loan commitments and standby letters of credit at March 31, 20202021 and December 31, 2019,2020, respectively, issued to borrowers with TDR modifications of loans.

Northern Trust may obtain physical possession of real estate via foreclosure on an in-substance repossession. As of March 31, 2020,2021, Northern Trust held foreclosed real estate properties with a carrying value of $1.6$1.5 million as a result of obtaining physical possession. In addition, as of March 31, 2020,2021, Northern Trust had loans with a carrying value of $20.8$6.5 million for which formal foreclosure proceedings were in process.
Collateral DependentTDR 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 System, the Federal Deposit Insurance Corporation, the National Credit Union Administration, the Office of the Comptroller of the Currency, and the Consumer Financial Assets.Protection Bureau, issued guidance in the April 7, 2020 AInteragency 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 assetinstitutions can apply ASC 310-40 Receivables – Troubled Debt Restructurings by Creditors. In accordance with the Interagency Guidance, a loan modification is collateral-dependentnot considered a TDR if the modification is related to COVID-19; the borrower had been current (not more than 29 days past due) when the borrower is experiencing financial difficultymodification program was implemented; and repayment is expectedthe 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 provided substantially throughgoverned by existing regulations and accounting policies.

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.
During the three months ended March 31, 2021, 38 loans with an aggregate principal amount of $42.9 million that had been granted payment deferrals were paid off.
Note 7 – Allowance for Credit Losses
During the first quarter of 2020, the Corporation implemented a change in the classification of certain loans and leases to specific segments to enhance the consistency of its reporting across various regulatory regimes. The allowance for credit losses as of and prior to December 31, 2019 remains unadjusted, as the impact of the reclassification on the allowance was immaterial.

An opening balance sheet adjustment related to the adoption of ASU 2016-13 resulted in an increase to the allowance for credit losses of $13.7 million, with a corresponding adjustment to decrease retained earnings by $10.1 million, net of tax.

Allowance and Provision for Credit Losses. The allowance for credit losses — 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,exposures, and specific borrower relationships — 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, 20202021 and 2019.

It represents the amount needed to maintain the allowanceAllowance for credit lossesCredit 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 provisionProvision for credit lossesCredit Losses may be either greater than or less than actual net charge-offs.

There was a $61.0$30.0 million provision forrelease of credit lossesreserves in the current quarter, as compared to noa $61.0 million provision in the prior-year quarter. The provision for credit losses, excluding available for sale securities, was a provision of $60.8 million. There were net charge-offsrecoveries of $0.7$0.9 million during the three months ended March 31, 2020,2021, as compared to net recoveriescharge-offs of $1.2$0.7 million for the three months ended March 31, 2019.2020. The provisionrelease of credit reserves in the current quarter was primarily due to an increasea 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 current andcontinued improvement in projected economic conditions resulting fromand portfolio credit quality relative to the ongoing COVID-19 pandemic and related market and economic impacts,prior quarter, with the largest increasedecreases primarily in the commercial and institutional, and commercial real estate, and private client portfolios.

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, assumes continued economic recovery from the challenges of COVID-19, with strong growth and a falling unemployment rate over the forecast horizon. An alternative scenario is also considered, which contemplates a resurgence of the virus, causing a double-dip recession.

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.

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.

The portion of the allowance attributable to loans and leases increased from $102.3 million at January 1, 2020 to $147.2 million at March 31, 2020. The portion of the allowance attributable to undrawn loan commitments and standby letters of credit increased from $28.8 million at January 1, 2020 to $40.4 million at March 31, 2020. The increasedecrease to the allowance for both loans and leases and the allowance for undrawn loan commitments and standby letters of credit for the three months ended March 31, 2021 was primarily due to an increasea 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 current andcontinued improvement in projected economic conditions resulting fromand portfolio credit quality relative to the ongoing COVID-19 pandemic and related market and economic impacts,prior quarter, with the largest increasedecreases primarily in the commercial and institutional, and commercial real estate, and private client portfolios.

Allowance Related to Credit Exposure Evaluated on a Collective Level.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 of Northern Trust’s loan and lease portfolio and undrawn loan commitments and standby letters of credit is mostlyprimarily based on internally developed loss data specific to the Northern Trust loanfinancial asset portfolio from a historical observation period that includes both expansionary and lease portfolio.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 / 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 Level.Basis. The allowance is determined through an individual evaluation of loans, leases, and lending-related commitments considered impaired 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 impaired 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.

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.

The portion of the allowance assigned to loans and leases is reported as a contra asset, directly following Loans and Leases 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.

Prior to the adoption of ASU 2016-13, Northern Trust recognized $4.4 million of cumulative Other-Than-Temporary-Impairment (OTTI) losses on the debt securities classified as other as of December 31, 2019. For debt securities with previous OTTI losses recorded, Northern Trust applied ASU 2016-13 on a prospective basis whereby the amortized cost basis of the impaired security remains unchanged immediately before and after adopting ASU 2016-13. The allowance recorded at January 1, 2020 for debt securities held to maturity equals the difference between the calculated expected loss and the amount of OTTI loss previously recorded and represents the cumulative effect adjustment required upon the adoption of ASU 2016-13.
The portion of the allowance attributable to debt securities held to maturity was $9.5 million at March 31, 2020 as compared to $6.6 million as of January 1, 2020. The increase to the allowance was primarily due to an increase in the reserve evaluated on a collective basis driven by current and projected economic conditions resulting from the ongoing COVID-19 pandemic and related market and economic impacts.

The allowance for credit losses for Northern Trust’s debt securities held to maturity portfolio is evaluated as follows:

Debt securities held to maturity 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.
55

Notes to Consolidated Financial Statements (unaudited) (continued)
Debt securities held to maturity 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.
Debt securities held to maturity 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 debt securities held to maturity 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 allowance assigned to the debt securities held to maturity portfolio is reported as a contra asset in Allowance for Credit Losses on the consolidated balance sheets.

Allowance for Other Financial Assets. The allowance for Other Financial Assets consists of the allowance for Cash and Due from Banks, Other Central Bank Deposits, Interest Bearing Deposits with Banks, Federal Funds Sold, 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 Debt Securities

Held to Maturity portfolio. It consists of a combination of externally and internally developed loss data, adjusted for the appropriate contractual term. Northern Trust’s portfolio is composed mostly of institutions within the “1 to 3” internal borrower rating category and areis expected to exhibit minimal to modest likelihood of loss. The allowance for credit losses related to Other Financial Assets was $1.1$1.7 million and $0.8 million as of March 31, 2021 and December 31, 2020, 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.

Northern Trust is organized around its two2 client-focused reporting segments: C&ISCorporate & Institutional Services (C&IS) and Wealth Management. Asset management and related services are provided to C&IS 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 C&IS and Wealth Management.
Reporting segment financial information, presented on an internal management-reportingmanagement 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.
Revenues, expenses and average assets are allocated to C&IS 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.

Note 14 – Revenue from Contracts with Clients
Trust, Investment, and Other Servicing Fees. Custody and fund administrationFund 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 C&IS clients. Investment managementManagement and advisoryAdvisory income contains revenue received from providing asset management and related services to Wealth Management and C&IS clients and to Northern Trust sponsored funds. Securities lendingLending income represents revenues generated from securities lending arrangements that Northern Trust enters into as agent, mainly with C&IS clients. Other income largely consists of revenues received from providing employee benefit, investment risk and analytic and other services to C&IS and Wealth Management clients.
Other Noninterest Income. Treasury management income represents revenues received from providing cash and liquidity management services to C&IS and Wealth Management clients. The portion of securities commissionsSecurity Commissions and trading incomeTrading Income that relates to revenue from contracts with clients is primarily comprised of commissions earned from providing securities brokerage services to Wealth Management and C&IS clients. The portion of other operating incomeOther 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 C&IS 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.

Northern Trust changed the plan design of its post-retirement health care plan as of January 1, 2021, which resulted in the recognition of negative prior-service cost at the time these changes were communicated to participants in August 2020. Concurrently, a further shift in population from active to inactive participants required an adjustment to the amortization period from the average remaining service period of active participants to the average life expectancy of the inactive participants. Negative prior service costs are being amortized on a straight-line basis over 13.9 years.

Note 1920 – Variable Interest Entities
Variable Interest Entities (VIEs) are defined within GAAP as entities which either have a total(1) lack sufficient equity investment that is insufficientat risk to permit the entity to finance its activities without additional subordinated financial support, or whose(2) have equity investors that lack attributes typical of an equity investor, such as the characteristicsability 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 a controlling financial interest.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 or other counterparties that provide other forms of support, such as guarantees, subordinated fee arrangements, or certain types of derivative contracts, 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 entityentity’s economic performance and, athrough 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.
Leveraged Leases. In leveraged leasing transactions, Northern Trust acts as lessor of the underlying asset subject to the lease and typically funds 20 - 30% of the asset’s cost via an equity ownership in a trust with the remaining 70 - 80% provided by third-party non-recourse debt holders. In such transactions, the trusts, which are VIEs, are created to provide the lessee use of the property with substantially all of the rights and obligations of ownership. The lessee’s maintenance and operation of the leased property has a direct effect on the fair value of the underlying property, and the lessee also has the ability to increase the benefits it can receive and limit the losses it can suffer by the manner in which it uses the property. As a result, Northern Trust has determined

70

Notes to Consolidated Financial Statements (unaudited) (continued)


that it is not the primary beneficiary of the leveraged lease trust VIEs given it lacks the power to direct the activities that most significantly impact the economic performance of the leveraged lease trust VIEs.
Northern Trust’s maximum exposure to loss as a result of its involvement with leveraged lease trust VIEs is limited to the carrying amounts of its leveraged lease investments. The carrying amounts of these investments, which are included in Loans and Leases on the consolidated balance sheets, were $42.8 million and $42.6 million as of March 31, 2020 and December 31, 2019, respectively. Northern Trust’s funding requirements relative to the leveraged lease trust VIEs are limited to its invested capital. Northern Trust has 0 other liquidity arrangements or obligations to purchase assets of the leveraged lease trust VIEs that would expose Northern Trust to a loss.
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
66

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, 20202021 and December 31, 2019,2020, the carrying amounts of these investments in community development projects that generate tax credits, included in Other Assets on the consolidated balance sheets, totaled $746.2$908.1 million and $749.3$919.6 million, respectively, of which $697.8$863.6 million and $700.3$874.0 million are VIEs as of March 31, 20202021 and December 31, 2019,2020, respectively. As of March 31, 20202021 and December 31, 2019,2020, liabilities related to unfunded commitments on investments in tax credit community development projects, included in Other Liabilities on the consolidated balance sheets, totaled $362.7$313.7 million and $376.2$351.6 million, respectively, of which $342.5$298.3 million and $354.3$335.9 million related to undrawn commitments on VIEs as of March 31, 20202021 and December 31, 2019,2020, respectively. Northern Trust’s funding requirements are limited to its invested capital and undrawn commitments for future equity contributions. Northern Trust has 0 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 $16.3$23.0 million and $16.4$16.3 million for the three months ended March 31, 20202021 and 2019,2020, 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 $50.2 million of money market mutual fund fees for the three months ended March 31, 2021 related to the low-interest-rate environment and certain competitive factors. Northern Trust did 0t waive any money market mutual fund fees for the three months ended March 31, 2020. Northern Trust does 0t 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, 2021, and December 31, 2020, Northern Trust had $100.0 million of investments valued using net asset value per share and included in Other Assets and had $74.6 million in unfunded commitments related tono seed capital investments. As of December 31, 2019, Northern Trust had $112.0 million of investments valued using net asset value per share and included in Other Assets and had 0no unfunded commitments related to seed capital investments.
Note 2021 Commitments and Contingent Liabilities
Commitments, Letters of CreditOff-Balance Sheet Financial Instruments, Guarantees and Indemnifications.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 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.

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. Standby letters of credit outstanding and financial guarantees were $2.4 billion as of both March 31, 2020 and December 31, 2019.
Financial guaranteesGuarantees are issued by Northern Trust to guarantee the performance of a client to a third party under certain arrangements.
As partCommercial Letters of its securities custody activities and at the directionCredit 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 lendslending securities owned by clients to borrowers who are reviewed and approved by the Northern Trust Capital Markets Credit Committee.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, 20202021 and December 31, 20192020 subject to indemnification was $139.1$176.4 billion and $138.1$157.5 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 0 liability was recorded as of March 31, 20202021 or December 31, 2019,2020, related to these indemnifications.
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. NaN 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, 2020,2021, the Corporation has estimated the range of reasonably possible loss for these matters to be from 0 to approximately $20$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.

Notes to Consolidated Financial Statements (unaudited) (continued)

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 2 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. The Public Prosecutor’s Office of France has appealed the appellate court’s decision toIn January 2021, the Cour de Cassation, the highest court in France.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, and September 27, 2019, Visa deposited an additional $600 million and $300 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$123.1 million and $99.9$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 0, as of March 31, 20202021 and December 31, 2019.2020.
Note 2122 – 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 available for sale debt securities and long-term subordinated debt and senior notes. Northern Trust applied the “shortcut”

fair value hedges during the three-month periods ended March 31, 20202021 and 2019.2020. 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 available for sale 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 0 material gains or losses reclassified into earnings during the three-month periods ended March 31, 20202021 and 2019,2020, as a result of the discontinuance of forecasted transactions that were no longer probable of occurring. It is estimated that net losses of $8.0 million and gains of $2.6 million and $16.9$287.9 million will be reclassified into net income within the next twelve months relating to cash flow hedges of foreign-currency-denominated transactions and cash flow hedges of foreign-currency-denominated debt securities, respectively. It is estimated that net gains of $0.4 million will be reclassified into net income upon the receipt of interest payments on earning assets within the next twelve months relating to cash flow hedges of available for sale debt securities. As of March 31, 2020,2021, 23 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.

investment hedge gains of $142.7$82.7 million and $28.6$142.7 million were recognized in AOCI related to foreign exchange contracts for the three months ended March 31, 2021 and 2020, and 2019, 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, 20202021 and 20192020 for derivative instruments not designated as hedges under GAAP.

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, 2020 and December 31, 2019.
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. However, Northern Trust’s repurchase agreements and reverse repurchase agreements 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 $360.7$189.0 million and $415.2$206.1 million, respectively, as of March 31, 2020,2021, and $196.3$111.0 million and $2.0$49.0 million, respectively, as of December 31, 2019,2020, 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 $935.7$401.6 million and $766.2$1,648.2 million at March 31, 20202021 and December 31, 2019,2020, respectively. Cash collateral amounts deposited with derivative counterparties on those dates included $922.7$391.1 million and $327.1$1,044.0 million, respectively, posted against these liabilities, resulting in a net maximum amount of termination payments that could have been required at March 31, 20202021 and December 31, 2019,2020, of $13.0$10.5 million and $439.1$604.2 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, 2020,2021, 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, 2020,2021, 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.

PART II — OTHER INFORMATION
Item 1. Legal Proceedings
The information presented under the caption “Legal Proceedings” in Note 2021 Commitments and Contingent Liabilities included under Part I, Item 1 of this Form 10-Q is incorporated herein by reference.
Item 1A. Risk Factors

Our business, results of operations, and financial condition have been, and will likely continue to be, adversely affected by the ongoing COVID-19 pandemic. 

The ongoing COVID-19 pandemic, and governmental and societal responses thereto, have had a severe impact on recent global economic and market conditions, including significant disruption of, and volatility in, financial markets; global supply chain disruptions; and the institution of social distancing and shelter-in-place requirements that have resulted in temporary closures of many businesses, lost revenues, and increased unemployment.

These conditions have impacted- or are expected in the future to impact-our business, results of operations, and financial condition negatively, including through lower revenue from certain of our fee-based businesses; lower net interest income resulting from lower interest rates; increased provisions for credit losses; impairments on the securities we hold; and decreased demand for certain of our products and services. Additionally, our liquidity and regulatory capital could be adversely impacted by volatility and disruptions in the capital and credit markets; volatility in foreign exchange rates; deposit flows; and continued client draws on lines of credit. Our business operations may also be disrupted if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the pandemic.

While governmental authorities have taken unprecedented measures to provide economic assistance to individual households and businesses, stabilize the markets, and support economic growth, the success of these measures is unknown and they may not be sufficient to mitigate fully the negative impact of the ongoing pandemic. Further, some measures, such as a suspension of mortgage and other loan payments and foreclosures, may have a negative impact on our business, while our participation in other measures could result in reputational harm, litigation, or regulatory and government actions, proceedings, or penalties.

The extent to which the COVID-19 pandemic impacts our business, results of operations and financial condition will depend on future developments, which are highly uncertain and are difficult to predict, including, but not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. The ongoing pandemic may also have the effect of heightening many of the other risks described in the section entitled “Risk Factors” in our most recent Annual Report on Form 10-K and any subsequent filings with the U.S. Securities and Exchange Commission.

On July 17, 2018, the Corporation’s Board of Directors authorized the Corporation to repurchase up to 25.0 million shares of the Corporation’s common stock. The repurchase authorization approved by the Board of Directors has no expiration date, thus the Corporation retains the ability to resume repurchases thereunder when circumstances warrant and applicable regulation permits. On December 18, 2020, the Federal Reserve extended its capital distribution limits into the first quarter of 2021 with certain modifications, which included continuing to limit dividend payments and share repurchases based on recent income. During the first quarter of 2021, the Corporation restarted its share repurchase program in accordance with such limitations. On March 25, 2021, the Federal Reserve announced that the temporary and additional restrictions on bank holding company dividends and share repurchases currently in place may end after June 30, 2021, depending on results from upcoming stress tests.
